Description

  TECHNICAL FIELD The present invention relates to a baby carrier (childcare band) that assists and carries an infant when it is carried or carried, and in particular, a baby having improved comfort and hygiene characteristics during holding. It is about career.

When holding an infant using a baby carrier when holding or carrying a baby, a part of the baby carrier will be applied to a part of the infant's body. Since the body temperature is high due to the immature adjustment function and the same holding posture is maintained for a long time, the user who is in close contact with the baby and the infant during use of the baby carrier has a high body temperature and is likely to sweat. Moisture such as stuffiness is also likely to occur.
In particular, in the hug that holds the infant vertically on the chest abdomen side of the user's body and the piggyback that holds the infant vertically on the user's back side, the holding form that the infant is in close contact with the user Therefore, heat and stuffiness are likely to occur due to the mutual transmission of heat between the user and the infant, and the user and the infant are uncomfortable, and the rash and diaper rash may occur when the user and the infant are used for a long time. In addition, when a so-called head hood that covers and supports the infant's rear head is used, the entire body of the infant is wrapped when the head hood is used, so that the infant is more likely to sweat. Especially for younger infants with sensitive skin and unstable posture, it is necessary to maintain a high degree of adhesion with the user in order to maintain stable and less burdensome, with less glare on the body, The effects of heat and stuffiness are significant.

  In addition, due to the increase in humidity and temperature due to stuffiness when the baby is held by the baby carrier in this way, sweat sweated from the user or infant's body due to an increase in the body temperature of the user or infant adheres to the baby carrier. By doing so, it becomes a hotbed of bacteria, and there is a risk of causing the growth of bacteria and generation of unpleasant odor in the baby carrier. In particular, the frequency of use of baby carriers has been increasing in the present age when the nuclear family is becoming more advanced, and furthermore, the development of baby carriers that can be used from the neonatal period has made it possible to use them for a long time. With regard to baby carriers that touch sensitive skin, an increasing number of users are concerned about cleanliness and hygiene.

  On the other hand, if the baby carrier pursues comfort, such as ease of pressure, shaking, shock, and stability of the infant's posture and holding, it is necessary to improve cushioning at the part applied to the infant's back and abdomen. Therefore, conventionally, as described in Patent Document 1, for example, a soft urethane foam, a polyolefin-based foam, or the like having a low resilience is used for a portion applied to the infant's back side. Also, rigid foamed urethane foam, polyolefin foam, etc. may be used as the core material to prevent the sinking of the upper body from the lower back and keep the infant's body in a stable support state. is there. Furthermore, in order to reduce the load on the user, urethane foam, polyolefin foam, or the like may be used for a shoulder belt or a waist belt worn on the user.

JP 2006-130016 A

  However, such urethane materials and polyolefin foams are basically inferior in breathability and moisture permeability, and heat and moisture that have entered the inside are difficult to escape to the outside. End up. In particular, the closed-cell foaming type has a heat storage property, which further promotes thickness and stuffiness. In addition, urethane materials and polyolefin foams may be damaged, deformed, or sag by washing, and it takes time to dry. I am worried.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a baby carrier that has cushioning properties but is resistant to stuffiness and can be held comfortably and has improved hygiene characteristics.

  The baby carrier of the invention of claim 1 is applied to the infant's body and the continuous linear body made of a synthetic resin is irregularly meandered and intertwined as a cushioning material in the holding part for holding the infant, and In the meandering state, it is fused everywhere, and the space between the continuous filaments communicates to have a three-dimensional network structure having air permeability.

  Here, the holding unit is a member that is applied to the infant's body and protects the infant, and may be used depending on the purpose of the baby carrier (holding mode such as a cuddle or piggyback, age of the target infant), type, and the like. Some members are applied only to the other members, while other members may be provided to the infants and other users (parents) who hold the infants and support them. In other words, some members are applied only to the infant's non-user side, while others include both a member applied to the infant's anti-user side and a member applied to the infant's user side. In addition, the use of the three-dimensional network structure may be used only for a member applied to the infant's non-user side, or may be used only for a member applied to the infant's user side. It may be used for both a member applied to the side opposite to the user and a member applied to the user side of the infant.

  The cushioning material is not limited to its purpose as long as it has a buffering function. For example, the cushioning material (elasticity) is enhanced, the contact with the body is improved, and the supporting force is enhanced. And those arranged for the purpose of improving fit and the like.

The three-dimensional network structure has a cushioning property in which a continuous linear body made of a synthetic resin meanders irregularly and is fused in the meandering state. That is, even if the space between the continuous filaments is deformed by an external force, the space is restored when the external force is released. And the space between continuous filaments is connecting, and it has air permeability by the high porosity of 70 to 98% normally. The three-dimensional network structure is wrapped in an exterior fabric to constitute the holding unit.
The manufacturing technique of this three-dimensional network structure is well-known in the patent gazette etc. which are mentioned later. This three-dimensional network structure is arranged so that the elastic change in the thickness direction in the vertical direction is large with respect to the front and back surfaces of the holding portion facing each other, and the expansion and contraction in the direction parallel to the front and back surfaces is small. The distinction between the front surface and the back surface is not particularly limited. As described above, the elasticity of the three-dimensional network structure can be arbitrarily selected, so that the number of types of synthetic resins to be selected for the regeneration process is small. The elasticity of the three-dimensional network structure changes when the infant is held, depending on the holding force or the movement of the infant and breathes.

The holding part of the baby carrier of the invention of claim 2 is such that the portion applied to the anti-user side of the infant's body is wrapped in the outer fabric made of a front fabric and a back fabric facing the front fabric It is composed of a three-dimensional network structure.
The part of the infant that is placed on the opposite side of the user that holds or rides the infant is applied to the infant's back when the infant is held face-to-face or carried forward.

The holding part of the baby carrier of the invention of claim 3 is a three-dimensional structure in which a portion applied to a user side of the infant's body is wrapped in the outer fabric made of a front fabric and a back fabric facing the front fabric It consists of a net-like structure.
The part of the user who holds or rides the infant on the side of the infant is disposed between the infant and the user who supports the infant, and when carrying the infant facing or facing forward, It applies to the crotch side and the abdomen side opposite to the dorsal side of the infant's body.

A part or the whole of the outer fabric in which the three-dimensional network structure of the baby carrier of the invention of claim 4 is placed is formed of mesh-like fibers that allow air to enter and exit.
Here, the mesh-like fiber may be any one that allows air to flow, and may use a fabric with a slightly coarse texture and a low density, or the fabric may have a stitch shape (net shape). However, the present invention is not limited thereto. For example, air may be allowed to flow by forming a plurality of through holes (openings) having a predetermined shape in the cloth.
Preferably, at least a part or all of the surface applied to the infant's body is formed of mesh fibers.

According to the baby carrier of the first aspect of the present invention, the buffer material disposed on the holding portion that holds the infant by being applied to the infant's body, the continuous linear body made of synthetic resin meanders irregularly. In addition, they are intertwined, and are fused in various places in the meandering state, and the space between the continuous filaments communicates to form a three-dimensional network structure having air permeability. According to this three-dimensional network structure, when an external force is applied, the curvature of the curved continuous filaments constituting the same changes, the space between the continuous filaments is deformed, and the external force is released, The striatum returns to its original curvature, and can express the cushioning properties (elasticity) that recover the space.
Moreover, the space between the continuous filaments constituting the three-dimensional network structure is communicated, and the air permeability is excellent.In particular, the space is also deformed by the movement of infants and users, and the flow of air is generated. Heat hardly stays and can prevent the occurrence of stuffiness.
Therefore, comfortable holding for the infant is obtained, and the burden on the infant is reduced even when used for a long time.

And, since moisture and heat hardly stay in the three-dimensional network structure in this way, it is difficult for bacteria and fungi to propagate, and further, the space between the continuous striatal bodies communicates with each other to make air permeability and moisture permeability. It is excellent in that it dries quickly, and the continuous filaments that make up the three-dimensional network structure are made of synthetic resin. They are irregularly meandered and intertwined, and are fused in a meandering state everywhere. Therefore, it has the strength to withstand repeated washing, and characteristics such as cushioning properties are unlikely to deteriorate even after repeated washing. Therefore, hygiene and cleanliness can be maintained.
In this way, a baby carrier that has cushioning properties but is resistant to stuffiness and can be held comfortably and has improved hygiene characteristics.
Further, for example, a shoulder belt portion that is attached to a shoulder of a user holding the infant, a waist belt portion that is attached to a waist of a user holding the infant, and a side opposite to the user of the infant as the holding portion The elasticity made of the three-dimensional network structure can be arbitrarily selected depending on the part applied to the user and the part applied to the user side of the infant as the holding portion, so that the elasticity can be selected at an appropriate place.

  According to the baby carrier of the second aspect of the present invention, since the three-dimensional network structure is disposed in a portion of the holding portion that is applied to the infant's body on the non-user side. In addition to the effects of the above, the three-dimensional network structure is arranged in a part that supports a large area with respect to the infant's body, so that the three-dimensional network structure reduces pressure, shaking, and impact, and when used for a long time However, the posture of the infant is not overwhelmed and the burden can be reduced, but moisture and heat such as sweat from the infant are difficult to accumulate in the three-dimensional network structure, effectively preventing the infant's heat and stuffiness, and comfortable for the infant The higher the nature.

According to the baby carrier of the invention of claim 3, since the three-dimensional network structure is disposed in a portion of the holding portion that is applied to the infant's body on the user side. In addition to the effects described in 2, when the three-dimensional network structure is covered with a breathable exterior fabric, air passages are secured to release moisture and heat such as sweat from the user and infants. be able to. Moreover, even if the exterior fabric covering the three-dimensional network structure does not have air permeability, the space between the continuous filaments accommodates air, and the heat insulation effect by the three-dimensional network structure is obtained. Therefore, accumulation of heat and moisture due to close contact between the user and the infant can be prevented, and partial rise in body temperature and stuffiness can be prevented.
Therefore, it is possible to improve the holding comfort for the user and the infant.

  According to the baby carrier according to the invention of claim 4, since a part or all of the exterior fabric in which the cushioning material made of the three-dimensional network structure is placed is formed in mesh-like fibers that allow air to enter and exit, The fresh air is supplied to the space between the continuous filaments constituting the three-dimensional network structure, and the air held in the space between the continuous filaments is discharged, so that claims 1 to 3 are performed. In addition to the effect described in any one of the above, moisture and heat from infants and users can easily escape, and hygiene characteristics are further improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Note that, in the embodiments, the same symbols and the same reference numerals are functional portions common to those embodiments, and thus detailed description thereof is omitted here.

  First, the three-dimensional network structure 100 as a cushioning material used for the baby carrier 1 of the present embodiment will be described with reference to FIGS. 1, 2, 7 and 8.

  As shown in FIG. 1, the three-dimensional network structure 100 as a buffer material is composed of a continuous linear body 101 made of a synthetic resin that is irregularly meandering and intertwined, and is adhered to everywhere in a meandering state. Is.

  Such a three-dimensional network structure 100 is disclosed in Japanese Patent Application Laid-Open Nos. 7-173753, 7-6801, 2001-328153, 2006-97223, and International Publication No. 20111035736. JP-A-2016-528, JP-A-2013-40437, JP-A-2007-130059, etc., the production method of which is described, and the product thereof is, for example, Toyobo Co., Ltd. As "Breath Air (registered trademark)", C-CORE from C-Engine Co., Ltd., "Air Weave (registered trademark)" from Airweve, "Hytrel (registered trademark)" from Toray DuPont It is possible to use such a commercial product that is sold and publicly known.

As a precaution, an example of a method for manufacturing the three-dimensional network structure 100 will be briefly described. As shown in FIG. 2, a nozzle provided with a plurality of perforations in which a molten thermoplastic resin is formed on the bottom surface of the extruder 200. From the (die), the continuous linear body 101 is extruded vertically downward to be supplied between the endless conveyors 211 and 212 arranged in parallel in the cooling water 210 at the lower position.
At this time, the interval between the endless conveyors 211 and 212 is formed so that the gap is smaller than the outer shape of the extruded continuous resin strip 101 so that the continuous strip 101 does not leak from the endless conveyors 211 and 212. I have to. Further, the water temperature and depth of the cooling water 210 in the water tank, the extrusion temperature of the continuous filament 101, and the like are set relative to the speed and position of the endless conveyors 211 and 212.

  Thereby, when the continuous filament 101 is extruded from a plurality of nozzles formed on the bottom surface of the extrusion molding machine 200, the extrusion speed is set faster than the conveyance speed between the endless conveyors 211 and 212. When extruded from a plurality of nozzles, the shape is linear, but as the temperature drops, the pushing force becomes a force in the left-right direction to form a three-dimensional network, and the three-dimensional network changes depending on the descending speed of the endless conveyors 211 and 212. At this time, the descending speed of the endless conveyors 211 and 212 is set to be slower than the extrusion descending speed of the continuous filament 101, and the continuous filament 101 is curved and partially joined. That is, the endless conveyors 211 and 212 in which the continuous filament 101 in a molten state extruded from the extrusion molding machine 200 is rotated slower than the descent speed of the continuous filament 101 due to the buoyancy and resistance of the cooling water 210. Is curved in a three-dimensional direction due to contact with the wire, and the continuous filaments 101 are partially welded, the welded portion is cooled by the cooling water 210, and the contact portions of the continuous filaments 101 are firmly bonded. At the same time, the continuous filament 101 is fixed. In this way, the continuous filament 101 is curled (curled) and intertwined randomly, and is partially welded to form a three-dimensional network structure 100 having a specific thickness.

  In the three-dimensional network structure 100 manufactured in this way, when a synthetic resin material to be melted is extruded as a continuous filament 101, a large number of them are curved and intertwined irregularly at a high temperature, It is welded, has a three-dimensional network structure, is formed with a predetermined thickness and width, and a space is formed between the continuous filaments 101, and the space communicates with the porosity of 70% to 98%. Have And the curved continuous linear body 101 has the elasticity which returns to the original curvature, when the curvature of curvature changes with external forces and an external force is cancelled | released. For this reason, in the three-dimensional network structure 100, the curvature of the curvature of the continuous filaments 101 is changed by an external force, and the space between the continuous filaments 101 is deformed, but when the external force is released, The curvature of the strip 101 returns to the original curvature, and the elasticity is such that the space is restored. That is, even when an external force is applied, the entire three-dimensional network structure 100 is deformed, and the stress is absorbed and dispersed by the rubber elasticity of the synthetic resin, and when the stress is released, the original form is restored. It is recovered and has moderate elasticity (cushioning) and resilience. In particular, since the continuous filaments 101 are fused to each other, when an external force is applied, substantially the entire three-dimensional network structure 100 disposed on the baby carrier 1 is integrally deformed, so that pressure dispersibility is obtained. In addition, it is difficult to cause partial settling and has excellent durability. It is excellent in elasticity (cushioning property), resilience and the like due to energy conversion in which the entire three-dimensional network structure 100 is deformed integrally.

Moreover, since it is formed with the continuous linear body 101 which consists of synthetic resins, and the porosity is also 70%-98%, it is lightweight. Since it consists only of synthetic resin, it is excellent in recyclability.
Furthermore, the space between the continuous filaments 101 is larger than that of the urethane material and the polyolefin-based foam, and the space is also in communication. The porosity is 70% to 98%, more preferably 85% to 98%. By having a porosity, it is excellent in air permeability and water permeability. For this reason, it is difficult for water to accumulate, it has a quick drying property, and in particular, since the material is a synthetic resin, the elastic restoring force is also good, and it is difficult to cause breakage, deformation, and settling due to folding and washing during storage. It is excellent in durability without being damaged or deformed by sterilization such as sodium chlorite. That is, since the continuous filaments 101 are fixed to each other, the continuous filaments 101 are not moved or the entire shape is not collapsed by compression or washing, and the bulkiness or elasticity is reduced. There is little setback.
And by being excellent in air permeability and quick-drying in this way, heat and moisture are easily dissipated and the rise in temperature and humidity is prevented, so that the growth of microorganisms can be suppressed. Even if washing such as washing with water is performed, there is no fear of causing growth of microorganisms until drying, and it is hygienic because it can be kept clean by washing.

Here, as the continuous filaments 101 constituting the three-dimensional network structure 100, a thermoplastic resin is used. For example, polyethylene, polyester, EVA (ethylene vinyl acetate copolymer), polyolefin such as polypropylene, polyester such as polyethylene terephthalate, etc. And polyamides such as nylon 66, polyvinyl chloride, polystyrene, EMMA (ethylene methyl methacrylate copolymer), and PET. A mixture of a copolymer or an elastomer copolymerized on the basis of these synthetic resins may be used.
In particular, EVA resin is rich in elasticity and can have high pressure dispersibility that disperses stress concentration. In addition, since polyethylene has a high melting point, it does not change its physical properties even when sterilized with hot water, steam sterilization, etc., and is suitable for more sanitary use.
Thus, when the continuous filament 101 which comprises the solid network structure 100 is a thermoplastic resin, it is excellent also in recyclability. Further, plastic deformation due to temperature rise when using the baby carrier 1 is small, and characteristics such as cushioning properties are stably maintained.

  The fineness of the continuous filaments 101 forming the three-dimensional network structure 100 is preferably in the range of 100 to 100,000 dtex, more preferably in the range of 300 to 50000 dtex, and still more preferably in the range of 500 to 30000 dtex. . Within this range, repulsive force, tensile stress (anticompressive force), etc. are good, and sag due to stress concentration hardly occurs, and high elasticity (cushioning property) is maintained over a long period of time. For this reason, the posture of the infant B held when used as a cushioning material is also stable, and a comfortable holding feeling can be obtained.

  Moreover, the continuous linear body 101 which comprises the solid network structure 100 may be a continuous linear body which consists of not only the continuous linear body which consists of a filament of a single fineness but a filament with which the fineness differs. In addition to a single type, a plurality of types of synthetic resins may be used.

Furthermore, the continuous filament 101 may be a hollow tube (tubular shape), a solid tube, or its cross-sectional shape is not particularly limited, and may be a circular cross-section. It may be an irregular cross-section different from a circular cross-section such as a polygonal cross-sectional shape such as a triangle or a quadrangle, a Y-shaped cross-sectional shape, or a star-shaped cross-sectional shape.
Since the hollow tube (tube shape) is lighter, the solid line structure 100 having the same weight as that of the solid tube has a high density of the continuous filaments 101 and is hard. It is also possible to select the shape of the continuous striatal body 101 according to the part applied to the infant or the user's body. For example, in a region applied to an infant's buttocks, the use of the low-density three-dimensional network structure 100 made of solid continuous filaments 101 allows the infant's buttocks to be softly received with a soft touch, and the lowering of the buttocks is more enhanced. Can be stabilized. In addition, the use of the low-density three-dimensional network structure 100 at the site applied to the infant's ventral side and the user's side improves the adhesion between the infant and the user with a soft feel and improves the comfort of holding. . On the other hand, in the part applied to the infant's head and back, the infant has sufficient strength to support the infant's weight by using the high-density and hard three-dimensional network structure 100 formed of the hollow continuous filaments 101. The posture can be stabilized and the weight can be highly dispersed. Further, the waist belt portion and the shoulder belt attached to the user's waist and shoulders can be received and highly dispersed by the strength that firmly supports the weight of the infant by using the high-density three-dimensional network structure 100.

  In the present embodiment, when the three-dimensional network structure 100 is disposed on the baby carrier 1, the front and back end surfaces that have surfaces with the largest areas are located on the front side and the back side that are opposed to each other in the thickness direction. Most of the contact portions between the continuous filaments 101 are welded and flattened without exposing the continuous lengthwise ends of the stripes 101. That is, they are connected two-dimensionally. Thereby, there is no fear that the surface that hits an infant or a user gives a feeling of bumpiness or incongruity, and the exposed end portion in the length direction of the continuous filament 101 is caught by an exterior fabric 150 described later that covers the three-dimensional network structure 100. There is no damage. In addition, due to the two-dimensional connection, even when a local external force is applied to the surface, settling due to stress concentration does not easily occur and the external force is received by the surface. High pressure dispersibility to absorb and disperse water. Therefore, the burden on the body can be eased, the holding posture can be stabilized, the holding comfort and the contact with the body can be improved.

Note that such two-dimensional welding in which the end portions in the length direction of the continuous filament 101 are not exposed on the front and back end surfaces is formed by contact with the endless conveyors 211 and 212 facing each other. Of course, most of the contact portions between the continuous filaments 101 are welded and aligned in a flat shape without the continuous lengthwise ends of the continuous filaments 101 appearing on three or more outer peripheral surfaces. It may be.
In the case of carrying out the present invention, if the pair of opposed front and back end faces are such that the continuous lengthwise ends of the continuous linear body 101 do not appear, the surface layer is corrugated, continuous irregularities , Convex or concave shape, saw shape, corners may be formed in a curved surface (R) or chamfered shape.

Further, the three-dimensional network structure 100 may have a uniform overall density or may be dense.
In particular, if the front and back sides in the thickness direction are higher than the density of the inner layer, it is difficult to get loose, and a comfortable holding feeling with high pressure dispersibility can be obtained. On the other hand, for example, by increasing the density of the continuous filaments 101 on the other surface side rather than the one surface side that is applied to the infant's body, that is, the closer to the infant, the lower the density and elasticity. Softer, the farther away from the infant, the higher the density and the elasticity on the opposite side of the infant. can get.
Moreover, the characteristic and density may be changed in the thickness direction (in the form of a layer) by a combination of synthetic resins (continuous filaments 101) having different compositions and characteristics.

The density of the three-dimensional network structure 100 is adjusted by adjusting the distribution density of the continuous filaments 101 by adjusting a plurality of drilling positions and intervals of nozzles (dies) that extrude the continuous filaments 101 shown in FIG. Or by adjusting the thickness of the continuous filament 101 by adjusting the size of the plurality of perforations in the nozzle, or by adjusting the supply speed of the synthetic resin from the nozzle. . It can also be adjusted by changing the interval between the endless conveyors 211 and 212 and the rotational speed of the endless conveyors 211 and 212. Increasing the rotational speed of the endless conveyors 211 and 212 can reduce the rotational speed. It can be formed with high density by slowing down.
That is, in the three-dimensional network structure 100, even if it is the same thickness, the density is changed depending on the extrusion speed of the continuous filament 101 and the transport speed of the endless conveyors 211 and 212, thereby providing cushioning from soft to hard. it can. Further, it can be changed by the extrusion thickness of the continuous filament 101.

  Thereby, for example, as shown in FIG. 7, the density between the continuous filaments 101 is increased compared to the three-dimensional network structure 100 shown in FIG. 1, and the dense three-dimensional network structure 100 is used. Alternatively, as shown in FIG. 8, a low-density three-dimensional network structure 100 in which the density between the continuous filaments 101 is reduced as compared with the three-dimensional network structure 100 shown in FIG. 1 may be used.

  Incidentally, as shown in FIG. 2, the continuous line body 101 is placed on the upper part of the water tank containing the cooling water 210 in the lower part of the extrusion molding machine 200 before and after the continuous line body 101 reaches the cooling water 210. By installing a four-sided funnel-shaped guide plate (chute) 220 that is narrowed in order to receive and guide it to the endless conveyors 211 and 212, the continuous linear body 101 extruded from the hole of the nozzle (die). A part of the guide strip 220 slides on the slope of the guide plate 220 and is guided to the endless conveyors 211 and 212. At that time, the continuous filaments 101 are entangled and welded on the surface of the guide 220 plate, toward the inner layer. The surface layer having a high density can be formed by narrowing down. At the same time, the end surface of the surface layer is formed flat by sliding on the flat guide plate 220.

In the baby carrier 1 of the present embodiment, the three-dimensional network structure 100 used as a cushioning material is, for example, 25% compressive hardness (based on JIS K 6400-2, the three-dimensional network structure 100 has a diameter of 200 mm. The stress when compressed to 75% with a circular compression plate and then compressed again by 25%) is in the range of 10 N / φ200 or more and 200 N / φ200 or less, more preferably 15 N / φ200 or more and 180 N / φ200 or less. Is done. The average apparent density is in the range of 0.005 to 0.90 g / cm, more preferably 0.02 or more and 0.20 g / cm ³ or less, still more preferably 0.05 or more and 0.15 g / cm ³ or less. It is assumed to be inside. If it is within the above range, cushioning, shock absorption, and pressure dispersibility are good with moderate hardness, good contact with the body of the infant B or the user M, and the baby carrier 1 is worn for a long time. There is little stiffness and less burden. Further, the thickness of the three-dimensional network structure 100 can be selected depending on the arrangement location and the like, and is not particularly limited. However, if the thickness is within a range of 3 mm to 30 mm, more preferably 3 mm to 20 mm, a buffer function is easily exhibited. It has flexibility and flexibility so that it can be bent corresponding to the body shape of the infant B or the user M.

  Such a three-dimensional network structure 100 can be formed not only by extrusion molding but also by mold fitting, and the continuous filaments 101 are not limited to fusion bonding but are bonded by an adhesive. It may be a thing. In any case, the continuous wire body 101 made of synthetic resin is irregularly meandering and intertwined, and the three-dimensional network structure 100 formed by bonding in a meandering state is easy to manufacture and process. In addition, there are almost no pollution problems of chemicals used during production, dioxins are not generated during incineration, and recyclability is also high.

  As described above, the three-dimensional network structure 100 as a cushioning material used in the baby carrier 1 according to the present embodiment has the continuous linear body 101 made of synthetic resin irregularly meandering and intertwined, It melts everywhere in a meandering state, has a specific thickness, and communicates with the space between the continuous filaments 101 and has air permeability. Note that the directionality of ventilation and water permeability is not specified.

Next, an example of the baby carrier 1 using the three-dimensional network structure 1 having such a configuration as a cushioning material will be described mainly with reference to FIGS. 1 and 3 to 6.
The baby carrier 1 according to the present embodiment is a holding unit for holding the infant M applied to the body of the infant M by holding or riding the infant M, on the side opposite to the user M side such as a parent holding or holding the infant B. A main body 10 applied to the body of the infant B and supporting the weight of the infant B; an auxiliary holding section 20 connected to the lower part of the main body 10 and applied to the body of the infant B on the opposite side of the main body 10; It has a positioning seat portion 30 disposed between the main body portion 10 and the auxiliary holding portion 20. Furthermore, it is connected to the auxiliary holding part 20 and is connected to the pair of left and right shoulder belt parts 40 that are hung on the shoulder of the user M, and the lower end part of the main body part 10 and the auxiliary holding part 20 to be connected to the main body part 10 and the auxiliary holding part. The waist belt portion 50 is disposed in a direction perpendicular to the length direction of 20 and is worn around the waist of the user M.

The main body 10 applied to the body of the infant B on the opposite side of the user M holding the infant B is a face-to-face hug in which the face of the infant B and the user M face each other or the face of the infant B and the user M Like the forward facing piggyback facing in the same direction, when the infant B is held so that the abdomen of the body of the infant B faces the user M such as a parent holding the infant B, it is applied to the back side of the body of the infant B It is.
The main body portion 10 of the present embodiment is a substantially semi-elliptical head support portion 11 that is mainly applied to the head of the baby B and receives the head mainly when the baby B is held with a face-to-face hug or a forward-facing piggyback. And a back support part 12 that is applied from the head side of the infant B to the back and waist and receives mainly the back part, and a support part 13 that is applied from the back side of the infant B to the buttocks part and mainly receives the hip part. Are integrally formed.

In the present embodiment, a three-dimensional network structure 100 as a cushioning material is disposed on the main body portion 10 including the head support portion 11, the back support portion 12, and the heel support portion 13.
Specifically, as shown in FIG. 1B, the three-dimensional network structure 100 as a cushioning material is covered with an exterior fabric 150 including a front fabric 110 and a back fabric 120 and is disposed in the main body 10. The That is, the three-dimensional network structure 100 as a cushioning material is put in an exterior fabric 150 made up of a front fabric 110 and a back fabric 120 closed in a bag shape, and the main body 10 is configured.

  Thus, in the main body 10, the exterior fabric 150 made of two cloths, the front fabric 110 and the back fabric 120, wraps around the three-dimensional network structure 100 as shown in FIG. The front fabric 110 and the back fabric 120 may be formed by folding a single fabric, or may be formed by three or four. In particular, in the present embodiment, the front fabric 110 and the back fabric 120 may be folded and overlapped and sewn with two sewing threads, or a pie pin may be sewn with one of them. Alternatively, a bag shape may be formed by the front fabric 110 and the back fabric 120, and the three-dimensional network structure 100 may be inserted therein.

In the baby carrier 1 of the present embodiment, the outer fabric 150 of the front fabric 110 and the back fabric 120 constituting the main body 10 is at least the entire inner surface (infant B side) applied to the body of the infant B, or one The cloth which has air permeability is used in the position corresponding to the surface of the part, for example, the body of the infant B.
Examples of the breathable fabric include a net fabric having a mesh / mesh structure with a predetermined opening, a coarse fabric with a slightly rough texture, and an air layer having a specific thickness between the front and back net fabrics. A three-dimensional knitted fabric (double raschel) having a specific thickness formed by weaving the connecting yarn to be formed is used. By forming the exterior fabric 150 into a mesh-like fiber by using such a breathable fabric, the breathability is ensured, and the moisture absorption from the surface in contact with the infant B is increased, and moisture and heat are dissipated. can do. Hygroscopicity is also improved by using a material such as a cotton material with high water absorption.

  In particular, according to the three-dimensional knitted fabric (double raschel), against the generation of moisture and heat such as sweat of infant B and user M by the air layer formed by the connecting yarn woven between the mesh fabrics of the front and back, It has a volume that can accommodate the moisture and heat, and further, the movement of the user M and the movement of the infant B become the volume change of the air layer, and the air in the air layer is discharged and supplied. The sweat sweated from the body of M or the infant B can be quickly absorbed, and the heat of the body of the user M or the infant B can be released. Of course, because the mesh fabric and air layer on the front and back sides are excellent in air permeability and water permeability, moisture can be dried quickly. Furthermore, the air layer formed by the connecting yarn has some elasticity (cushioning), etc., and even if the infant B moves, the following change in the air layer does not cause a sense of incongruity, and the infant B's body shape fits in Good.

  Such a three-dimensional knitted fabric (double raschel) is manufactured by a woven fabric manufacturing machine such as a double raschel machine or tricot machine. The product is “Fusion (trade name)” from Asahi Kasei Co., Ltd. Since it is sold as “Aqueen (trade name)”, detailed explanation is omitted here.

When carrying out the present invention, the above-described fabric having air permeability may be used on the inner surface side of the main body 10, that is, the entire surface on the infant B side, or may be used partially. . In particular, it may be used only for the head support part 11 and the back support part 12 applied to the head and the back part where the infant B is likely to perspire. Also good. Only one of the head support part 11, the back support part 12, and the heel support part 13 may be used, only the head support part 11 and the back support part 12, only the head support part 11 and the heel support part 13, Only the abutment part 12 and the abutment part 13 may be used, or the head abutment part 11, the back abutment part 12 and the abutment part 13 may all be used. Of course, each part of the head support part 11, the back support part 12, and the padding part 13 may be sufficient.
Moreover, you may use not only the inner surface side of the main-body part 10 but the exterior cloth | dough 150 of the outer surface side of the main-body part 10, and you may use the cloth which has air permeability, the inner surface side (infant B side) and outer surface ( A structure that allows air to flow in the thickness direction on both the front and back surfaces of the baby B) is desirable. If the front and back surfaces of the main body 10 are formed of a predetermined mesh-like fiber, air passages in the thickness direction of the front and back surfaces are secured, so that the amount of ventilation increases and moisture and heat can be released more effectively. it can. Moreover, you may form in the two-layer structure which can coat | cover the non-breathable cloth with respect to the cloth which has air permeability in a specific part. In any case, in the exterior fabric 150, all or a part of the exterior fabric 150 forms an opening through which air is discharged and supplied by using a fabric having air permeability, so that a three-dimensional mesh shape inserted between the front fabric 110 and the back fabric 120 is formed. Any structure may be used as long as the air permeability of the structure 100 is utilized to maintain the air permeability.

  In addition, the fluid resistance which determines the inflow / outflow of air can be arbitrarily set by the size and number of mesh holes, that is, by selecting the mesh density. Furthermore, the mesh density may be changed according to the part of the infant B to be matched. For example, in the face of baby B and easy-to-touch parts, the fine mesh of the eyes improves the touch, and in the head support part 11 and the back support part 12 corresponding to the head and back part where the infant B tends to sweat, A rough mesh can ensure high air permeability. Further, the shape of the mesh may be determined in terms of design. The mesh structure is not necessarily required, and air circulation may be ensured by a plurality of openings.

  The exterior fabric 150 including the front fabric 110 and the back fabric 120 of the main body 10 can be formed of any fabric except for a fabric having air permeability. Further, the kind of the fabric may be changed according to the part of the infant B to be matched. For example, a soft fabric, a soft fabric with soft feeling, or a non-irritating fabric is used near the head of the infant B. A fabric with high hygroscopicity is used near the head and back of the infant B. The material of the fabric may be selected in terms of design and mechanical strength.

  And in the baby carrier 1 of this Embodiment, it consists of a synthetic resin as a buffering material inside the bag-shaped exterior fabric 150 which consists of the front fabric 110 and the back fabric 120 with which air permeability is ensured in this way. A continuous wire body 101 is irregularly meandering and entangled, and a three-dimensional network structure 100 having a specific thickness formed by welding in a meandering state is disposed.

The three-dimensional network structure 100 may be disposed throughout the main body 10 in accordance with the purpose of the baby carrier 1 (the age of the object to be retained, the retention form, etc.), the characteristics and characteristics of the commercial value, and the like. However, only a specific part may be provided. In other words, only the head support 11, the back support 12, or the heel support 13 may be disposed, or only the head support 11 and the back proof 12, the head support 11 and the heel support 13. Only the back support part 12 and the abutment part 13 may be provided, or the head support part 11, the back support part 12 and the abutment part 13 may be provided as a whole. Preferably, it is filled with an area equivalent to each part in order to prevent displacement, but may be a part of each of the head support part 11, the back support part 12, and the heel support part 13, in which case the part For example, a misalignment prevention means such as sewing on the exterior fabric 150 or forming a housing portion in the exterior fabric 150 is provided.
In addition, as described above, the three-dimensional network structure 100 can be adjusted in characteristics such as hardness, softness, elasticity, etc. according to its density, size, thickness, material of raw material, shape of the continuous filament 101, and the like. Therefore, for example, it is possible to select the three-dimensional network structure 100 having different characteristics (density, thickness, etc.) depending on the arrangement position and site, such as using a soft material for the back support portion 12 and a soft material for the support portion 13. It is.
The three-dimensional network structure 100 disposed in the main body portion 10 has a thickness of 3 mm or more and 30 mm or less, more preferably 3 mm or more and 20 mm or less. It is easily expressed and has flexibility and softness to the extent that it can be bent corresponding to the body shape of the infant B or the user M, and further, it is less bulky when being carried.

For example, by disposing the three-dimensional network structure 100 on the head support 11, the head of the infant B is supported to prevent glare, to prevent backward tilting, and to shock the head. Can be tempered. In addition, the surrounding sound can be attenuated to form a comfortable sleep environment.
In particular, the hardness at the time of 25% compression of the three-dimensional network structure 100 arranged in the head support 11 (the three-dimensional network structure 100 was compressed to 75% with a 200 mm-diameter circular compression plate and then compressed again by 25%. Stress) is preferably in the range of 10 N / φ200 or more and 180 N / φ200 or less, more preferably in the range of 10 N / φ200 or more and 130 N / φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 15 kg / φ150, more preferably 4 kg / φ150 to 10 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 10 kg / φ150 to 30 kg / φ150.
If it is within the above range, the head holder 11 that is applied to the head of the infant B firmly supports the head of the infant B without having to put a hard core material in the exterior fabric 150 separately. Since the head can be prevented from tilting and warping backward, the head of the infant B is firmly supported even when the infant B is held or when the infant B is asleep, and the head is prevented from being blurred. It is possible. Furthermore, the vibration and shock absorption by the user M walking and the like are high, and the burden on the head and neck of the infant B can be reduced.

Further, by arranging the three-dimensional network structure 100 on the backrest 12, the comfort for the infant B is improved, and the posture of the infant B and the stability of the holding are also improved.
In particular, the 25% compression hardness of the three-dimensional network structure 100 disposed in the backrest 12 is preferably in the range of 10 N / φ200 or more and 180 N / φ200 or less, more preferably 10 N / φ200 or more. , 150 N / φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 20 kg / φ150, more preferably 3 kg / φ150 to 15 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 15 kg / φ150 to 30 kg / φ150.
If it is within the above range, the back portion 12 applied to the back from the waist of the infant B without a hard core is supported firmly from the waist of the infant B to prevent falling. Thus, a stable posture of the infant B can be maintained, and even when the user M cannot reach the eyes, the infant B can be prevented from warping.

Further, by disposing the three-dimensional network structure 100 in the abutment portion 13, the buttocks of the infant B are likely to fall, the center of gravity of the infant B is stabilized, and the holding stability is improved. Moreover, the pressure applied to the buttocks of the infant B is easily dispersed, the sitting comfort is improved, and the burden on the infant B is reduced.
In particular, it is preferable that the hardness at 25% compression of the three-dimensional network structure 100 disposed in the holding portion 13 is within a range of 10 N / φ200 or more and 150 N / φ200 or less in the center portion 13A described later. Is in the range of 10 N / φ200 or more and 130 N / φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 20 kg / φ150, more preferably 3 kg / φ150 to 10 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 5 kg / φ150 to 25 kg / φ150.
If it is within the above range, the lower part of the buttocks of the infant B can be easily lowered, the center of gravity of the buttocks can be stabilized to prevent the position shift, thereby obtaining a stable sinking of the infant B and improving the holding stability. It is possible to hold in a comfortable posture with less burden on M and infant B. Moreover, even if it touches the leg of the infant B, it follows it, and the movement of the leg of the infant B is difficult to be restricted. In particular, even when holding an infant B of a young age before the neck is set, the knee of the infant B is easily bent down, so that the knee is bent at a position higher than the position of the buttocks of the infant B, and an M-shaped spread leg is formed. In a natural open leg posture, the center of gravity of the infant B is not on the leg side but on the buttocks, and the body shape of the infant B can be held with a low burden.

  Here, in the abutment portion 13 of the present embodiment, a center portion 13A that receives the center side of the buttocks of the infant B and a pair of left and right end portions 13B that are located on the left and right sides of the center portion 13A and that are near the thighs of the infant B It consists of and.

  In the baby carrier 1 according to the present embodiment, the center portion 13A and the left and right end portions 13B of the holding portion 13 are formed by draping, and the center portion 13A and the end portion 13B are located inside (center side). Is joined by a sewing line 13a that is curved in an arc shape toward the upper side, and further, the lower end portion of the abutment portion 13 is joined to the upper end portion of the main body belt portion 51 with respect to the main body belt portion 51 of the waist belt portion 50 described later. A three-dimensional accommodation space is formed by integrally connecting a straight sewing line and a sewing line (not shown) curved in an arc shape below the sewing line. This makes it difficult for the movement of the leg of the infant B to be restrained when held at a high position, which will be described later, and the position of the center of gravity of the buttocks of the infant B is easily stabilized.

  At this time, the connection between the central portion 13A and the end portion 13B in the holding portion 13 is performed by not making the three-dimensional network structure 100 inserted between the front fabric 110 and the back fabric 120 continuous, or by making the three-dimensional network structure 100 continuous. Even if the front fabric 110 and the back fabric 120 are stitched, or the three-dimensional network structure 100 itself is formed to be foldable, the central portion 13A and the end portion 13B are distinguished from each other, and the central portion An end portion 13B is formed so as to be bent toward the infant B side with respect to the surface of 13A.

  In particular, since the outer shape of the center portion 13A joined to the end portion 13B by the sewing line 13a is a shape curved toward the center side, that is, a shape narrower on the center side than the upper and lower end portions, When the three-dimensional network structure 100 is provided, the buttocks of the infant B are likely to fall, and the misalignment of the buttocks hardly occurs. Therefore, the infant B can be held in a comfortable posture with less burden, and the holding stability can be increased.

  In the case of carrying out the present invention, the thickness of the three-dimensional network structure 100 put in the outer fabric 150 of the front fabric 110 and the back fabric 120 is changed. Cushioning and flexibility of the three-dimensional network structure 100 put into the exterior fabric 150 of the front fabric 110 and the back fabric 120 by forming a recess so that the heel portion can freely fall by adding a change Also by adopting a structure that changes the sex, the drop of the buttocks of the infant B can be stabilized and the holding stability can be improved.

  Furthermore, since the outer edge of the end portion 13B of the abutment portion 13 comes into contact with the thigh of the infant B, it is easy to apply a large load to the thigh of the infant B. In 13B, the arrangement of the three-dimensional network structure 100 having a cushioning property (elasticity) higher than that of the central portion A can reduce the pressure of the infant B on the thighs. For example, the three-dimensional network structure 100 disposed in the end portion 13B preferably has a 25% compression hardness within a range of 10 N / φ200 or more and 180 N / φ200 or less, more preferably 10 N / φ200 or more. , 130 N / φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 15 kg / φ150, more preferably 4 kg / φ150 to 10 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 10 kg / φ150 to 30 kg / φ150.

Moreover, in the baby carrier 1 of the present embodiment, the horizontal width in the horizontal direction is narrow at the boundary between the backrest portion 12 and the abutment portion 13 and the design is such that the abutment portion 13 widens downward from there. In particular, the butting part 13 makes it easy for the baby B to drop the buttocks, but the three-dimensional network structure 100 disposed in the back rest part 12 and the three-dimensional network structure 100 disposed in the butting part 13 are cushions. By changing characteristics such as property and hardness, for example, the hardness of the three-dimensional network structure 100 disposed in the abutment portion 13 is made softer than that of the three-dimensional network structure 100 disposed in the back support portion 12. However, by reducing the cushioning property, the posture of the infant B can be firmly supported by the back support unit 12, but the buttocks of the infant B can be easily lowered by the support unit 13.
In particular, since the three-dimensional network structure 100 has high air permeability, even if the thickness of the three-dimensional network structure 100 is increased to increase cushioning properties and hardness, it is possible to prevent stuffiness.

  As described above, the hardness, repulsive force, and cushioning properties of the three-dimensional network structure 100 are determined by its density, size, thickness, material material, shape of the continuous filament 101, and the like. Therefore, the density of the three-dimensional network structure 100, the material of the raw material, and the shape of the continuous filaments 101 may be unified, and a desired hardness may be obtained by changing only the thickness, or the three-dimensional network structure 100. May be obtained to obtain a desired hardness, repulsive force, cushioning characteristics, etc. by changing the material to a uniform thickness, and changing the material of the constituent material, the shape of the continuous filament 101, the density, and the like. .

  As described above, according to the baby carrier 1 of the present embodiment, a bag-shaped exterior fabric 150 including the front fabric 110 and the back fabric 120 that are partially or entirely formed of a fabric having air permeability to ensure air permeability. In particular, a continuous filament 101 made of a synthetic resin is irregularly meandering and entangled as a buffer material in a specific part or in the whole, and it is fused in a meandering state everywhere. A three-dimensional network structure 100 having a specific thickness formed by communicating a space between the bodies 101 is inserted to form the main body 10.

  Therefore, a buffering action and cushioning properties (elasticity) can be obtained at the portion where the three-dimensional network structure 100 is disposed. In this three-dimensional network structure 100, the space between the continuous filaments 101 constituting the three-dimensional network structure 100 is continuous. Therefore, it has air permeability, preferably with a porosity of 70% to 98%. For this reason, even if the three-dimensional network structure 100 is provided as a cushioning material, air passages are formed by the gaps between the continuous filaments 101, and the three-dimensional structure is caused by the movement of the infant B or the user M. Since the flow of air is generated by the volume change of the space of the net-like structure 100, heat and moisture are less likely to stay, and it is difficult for the infant B to be hot or stuffy.

  Since the three-dimensional network structure 100 is excellent in air permeability and hardly retains moisture and heat as described above, the continuous filament 101 is formed by irregularly meandering of the continuous filament 101 made of synthetic resin. Because most of them are loop-shaped and it is difficult for synthetic resin waste to come out, bacteria, molds, etc. are difficult to propagate compared to urethane and polyolefin foams used as conventional cushioning materials. Odor due to permeation of sweat from M and propagation of bacteria, mold, etc. hardly occurs. Furthermore, the continuous space between the continuous filaments 101 is excellent in air permeability and moisture permeability, so that it has a quick drying property, and even if it is washed, the moisture will dry quickly, and there is a risk that bacteria will grow before drying. Without washing, hygiene and cleanliness can be maintained. It can dry quickly and prevent the growth of bacteria, mold, etc., even when the baby B is drooling or adhering to water such as spitting back. Therefore, hygiene characteristics are improved. Further, the continuous filaments 101 constituting the three-dimensional network structure 100 are made of synthetic resin, and they are irregularly meandering and entangled, and are fused in a meandering state everywhere. It has the strength to withstand, and even if it is repeatedly washed, characteristics such as cushioning and cushioning properties are unlikely to deteriorate. That is, since the continuous filaments 101 are fixed to each other, the continuous filaments 101 are not moved or the entire shape is not collapsed by compression or washing, and the bulkiness or elasticity is reduced. There is little setback.

  In particular, in the present embodiment, the three-dimensional network structure 100 is covered with an exterior fabric 150 that is partially or entirely made of a fabric having air permeability, and an air flow path is formed by the air permeability of the exterior fabric 150, The heat and moisture of the infant B's body can be released. Furthermore, since fresh air is supplied to the three-dimensional network structure 100 put in the outer fabric 150 due to the air permeability of the outer fabric 150, the exhaust of moisture and high-temperature air entering the three-dimensional network structure 100 is promoted. Is done. That is, the three-dimensional network structure 100 has a volume that can store moisture and heat against the generation of moisture and heat such as sweat of the infant B due to its high porosity, but the exterior fabric 150 that covers the moisture and heat is breathable. By having fresh air, fresh air is taken in and it becomes easy to escape moisture and heat. In particular, the movement of the user M and the movement of the infant B result in a change in the volume of the space (space) between the continuous filaments 101 constituting the three-dimensional network structure 100, thereby promoting the supply and discharge of air in the space. Is done. Therefore, sweat sweated from the body of the infant B through the exterior fabric 150 can be quickly absorbed, and the heat of the user M and the body of the infant B can be released. Therefore, it is difficult for moisture and heat to accumulate in the three-dimensional network structure 100, and the heat and stuffiness of the infant B can be reduced. In addition, the body temperature of the infant B is partially and abnormally prevented even when held for a long time, and there is little tingling and stickiness, and it is a countermeasure against sweating, heat and stuffiness, and sweating.

  More preferably, both the front fabric 110 and the back fabric 120 of the exterior fabric 150, that is, the both surfaces (front and back) of the main body 10 with the surface applied to the body of the infant B and the side surface opposite thereto are breathable. When the fabric is used, the air permeability in the thickness direction of the main body 10 is increased by the air permeability of the three-dimensional network structure 100 and the fabric of the front and back surfaces, so that moisture and heat can be released more effectively. It can be refreshed and refreshed. In addition, if both the front and back surfaces (opposite surfaces) of the main body 10 are mesh-like, the fluid resistance that determines the entry and exit of air according to the body shape and operation of the user M and the infant B can be arbitrarily set.

In this way, the continuous linear body 101 made of a synthetic resin is irregularly meandering and intertwined, and the three-dimensional network structure 100 having a specific thickness formed by welding in a meandering state everywhere. For example, although the void ratio is high, the continuous filaments 101 constituting the same are made of synthetic resin, and are subjected to external force over the entire surface because they are entangled and fused in a three-dimensional manner. Compared to urethane and polyolefin-based foams, the weight is reduced as equivalent cushioning properties. Therefore, the weight and carrying burden for the user M who wears can be reduced.
In addition, the three-dimensional network structure 100 has faster recovery characteristics than conventional urethane and polyolefin-based foams that have been used as cushioning materials for the baby carrier 1, and has a fitting property and embrace that follows the body movement of the infant B. Holding property can be obtained, and holding comfort and holding stability can be improved. Therefore, even if the thickness is reduced, an appropriate cushioning property can be obtained and the bulkiness can be reduced.

  In addition, according to the three-dimensional network structure 100 in which the continuous filaments 101 are entangled three-dimensionally and have a continuous space, the concentration of weight stress can be reduced by uniformly supporting the area of the infant B. That is, the pressure receiving area is widened by the provision of the three-dimensional network structure 100, and the pressure applied to the infant B is easily dispersed. Therefore, the burden concerning the body shape of the infant B can be reduced. In particular, in the abutment portion 13 where the center of gravity of the infant B comes, the three-dimensional network structure 100 is disposed so that the pressure applied to the buttocks of the infant B is dispersed even when the infant B is held for a long time. It becomes comfortable and the burden on the buttocks of the infant B is reduced.

  In the present embodiment, even if the three-dimensional network structure 100 is disposed in the head support part 11 and the back support part 12, the front fabric 110 and the back fabric 120 at the boundary between the head support part 11 and the back support part 12. The three-dimensional network structure 100 placed between the outer fabrics 150 is not continuous, or even if the three-dimensional network structure 100 is continuous, the three-dimensional network structure 100 itself can be bent, so 11 and the backrest portion 12 are distinguished, and the headrest portion 11 can be bent with respect to the surface of the backrest portion 12. Thereby, although the back part 12 supports the back part of the infant B from the waist stably, the head part 11 is easily inclined with respect to the surface of the back part 12 according to the weight of the head of the infant B. (It is easy to bend) and the head and neck of the infant B can be protected so as not to overload the head and neck of the infant B. Further, the field of view of the infant B can be expanded by using the head support part 11 by bending the head support part 11 on the side opposite to the infant B side with respect to the surface of the back support part 12 according to the growth of the infant B.

  Furthermore, in the baby carrier 1 of the present embodiment, on the side where the infant B of the main body 10 is arranged, the surfaces of the head support 11 and the back support 12 at the boundary between the head support 11 and the back support 12. A connection portion 14 having a substantially triangular shape is provided so as to protrude from the right side, and this connection portion 14 supports the tilt of the head of the infant B in the left-right direction, prevents glare and prevents a burden on the head and neck of the infant B. Can be reduced. In particular, by forming the connecting portion 14 with a material having cushioning properties, the impact and the head and neck of the infant B can be protected. And it is also possible to arrange | position the three-dimensional network-like structure 100 as a buffer material in this connection part 14. FIG. In other words, the three-dimensional network structure 100 may be inserted between the front fabric 110 and the back fabric 120 of the exterior fabric 150 constituting the connection portion 14.

The head support 11 is provided with a pocket-shaped storage portion having a predetermined storage volume (not shown), and is a surface on the opposite side of the main body 10 shown in FIG. A slide fastener 15 (a hook, a button, an adhesive cloth, etc.) for opening and closing a storage portion (not shown) on the design surface side when the user M is wearing the baby carrier 1 may be used. ), And can accommodate a head hood (not shown) having a predetermined area covering the head of the infant M, items such as a cooling agent and a towel. For example, the head hood (not shown) has one end fixed to the storage portion by sewing or the like, and the other end connected to the shoulder belt portion 40 (for example, a buckle, hook, eggplant, carabiner, D lock, quick catch, The head of the infant B is covered and supported from the back of the head, and the head of the infant B falls backwards even when the infant B is sleeping. It functions as a cover that hides breastfeeding when the baby B is fed while being held while the baby carrier 1 is worn, or the like is prevented.
In addition, it is desirable for this head hood to have air permeability, and by using the three-dimensional network structure 100 as a cushioning material, air permeability can be ensured.

  And in the baby carrier 1 of this Embodiment, the main body part 10 in which the head support part 11, the back support part 12, and the support part 13 are integrally formed in this way is the lower end part on the side of the support part 13. The waist belt portion 50 is sewn with a linear sewing line and an arc-shaped sewing line (not shown). The main body portion 10 and the waist belt portion 50 are disposed in a substantially inverted T shape as a whole, and are sewn integrally with the waist belt portion 50 by sewing the lower end of the main body portion 10 and the vicinity thereof, thereby providing a waist belt. The main body 10 can be bent in a direction perpendicular to the surface direction of the portion 50.

  The waist belt portion 50 is disposed in a direction substantially orthogonal to the length direction (vertical direction) of the main body portion 10 and the auxiliary holding portion 20 below the main body portion 10 and the auxiliary holding portion 20 described later. As a form in which the weight (the weight of the infant B) is distributed so that it can withstand the strength because it receives a lot of body weight, and it does not overload the body shape of the user M even if it is attached to the waist of the user M And a main body belt portion 51 that is integrated with the main body portion 10 and an auxiliary holding portion 20 that will be described later, and a fabric belt that has a wide belt and has a buckle with an adjuster disposed at both ends in the longitudinal direction of the main body belt portion 51. It comprises a pair of left and right length adjusters 52. The waist belt portion 50 can be fixed around the waist of the user M by the coupling engagement of the coupling insert 53 of the buckle with adjuster provided in the length adjusting unit 52 and the coupling receiver 54, and the coupling insertion By making the tool 53 and the connection receiver 54 connectable, the user 53 can freely attach and detach the waist of the user M.

  As described above, in the waist belt portion 50, the pair of left and right length adjusting portions 52 provided at both ends of the main body belt portion 51 are predetermined so that the belt length necessary for attaching the user M around the waist is determined. The connection insertion tool 53 and the connection receiver 54, each of which is made of a pair of male and female buckles with an adjuster, have an adjuster function, so that the length of the waist of the user M can be adjusted. . The adjuster may be an independent adjuster as long as the belt length can be adjusted, or may be an integrated adjuster.

  The main body belt portion 51 having a wide vertical width is formed of, for example, a material having a predetermined flexibility, flexibility, elasticity, hardness, and the like in which a cushioning material is inserted between the outer fabric 150 of the front fabric 110 and the back fabric 120. It improves the familiarity of the user M around the waist, enhances the fit so as not to bite in, makes it easier to distribute the load on the waist of the user M, and reduces the burden on the user M ing. Preferably, in the main body belt portion 51 as well, it is possible to prevent stuffiness and reduce discomfort by using the breathable fabric as described above for all or part of the exterior fabric 150 constituting the body belt portion 51. . In addition, the hygroscopicity can be improved by forming at least the inner surface that touches the waist of the user M with a water absorbent cotton fabric or the like.

  When practicing the present invention, the outer fabric 150 of the front fabric 110 and the back fabric 120 is composed of a core material made of hard urethane or polyolefin foam as a cushioning material and a soft urethane or polyolefin foam. The main body belt portion 51 can be formed using a cushion material, or the main body belt portion 51 can be formed by inserting a three-dimensional network structure 100 as a cushioning material between the outer fabric 150 of the front fabric 110 and the back fabric 120. It is also possible to configure.

In particular, in the main body belt portion 51, by providing the three-dimensional network structure 100 as a cushioning material, it is lighter and has higher air permeability than urethane and polyolefin-based foams, and can reduce moisture and the like. It becomes possible to keep it.
That is, since the three-dimensional network structure 100 is excellent in air permeability, air passages are formed, and the volume of the space in the three-dimensional network structure 100 is also changed by the movement of the user M, so that the air flow. Is promoted, moisture and heat are less likely to stay, and stuffiness can be reduced.

  In particular, if the whole or part of the three-dimensional network structure 100 is covered with a breathable fabric, fresh air is taken in and moisture and heat are likely to escape. In addition, due to the high porosity of the three-dimensional network structure 100, the movement of the user M has a volume that can accommodate the moisture generated by the user M such as sweat, but the movement of the user M is three-dimensional network structure. Since the air in the air layer changes in volume in 100 and the air in the air layer is discharged and supplied, the sweat sweated from the body of the user M or the infant B can be quickly absorbed through the breathable fabric, Further, the moisture and heat of the body of the user M and the infant B can be released. Therefore, moisture and heat are not accumulated in the three-dimensional network structure 100, and heat and stuffiness can be reduced, and even when used for a long time, the body temperature is partially prevented from rising abnormally. It also becomes a countermeasure and can reduce discomfort due to the feeling of stuffiness around the waist of the user M.

  Of course, the front and back surfaces of the front and rear fabrics 110 and 120 constituting the main body belt portion 51, that is, the front and back surfaces of the main body belt portion 51, which is the surface applied to the body of the user M and the opposite surface, are air permeable. In the case where the cloth having the fabric is used, stuffiness is further reduced by increasing the air flow rate in the thickness direction due to the air permeability of the three-dimensional network structure 100 and the air permeability of the front and back fabrics.

  When the three-dimensional network structure 100 is used as a cushioning material for the main body belt portion 51 in this way, the main body belt portion 51 is excellent in air permeability and hardly retains moisture and heat. In comparison with the above, bacteria and molds are also difficult to propagate, and permeation of sweat from the user M and odors caused by the propagation of bacteria and molds can be prevented. Furthermore, according to the three-dimensional network structure 100, the continuous space is excellent in air permeability and water permeability and moisture permeability, so that it has a quick drying property. Hygiene and cleanliness can be maintained by washing without fear of breeding. Therefore, hygiene characteristics are improved. In addition, the continuous filaments 101 constituting the three-dimensional network structure 100 are made of synthetic resin, they are irregularly meandering and entangled, and are fused in a meandering state everywhere. Has the strength to withstand washing, and the cushioning properties are unlikely to deteriorate even after repeated washing.

Furthermore, the continuous linear body 101 is entangled three-dimensionally, and the pressure receiving area around the waist of the user M is widened by the arrangement of the three-dimensional network structure 100 having a continuous space, and the pressure applied to the user M is dispersed. It is easy to reduce the weight that the user M feels.
In particular, the three-dimensional network structure 100 disposed in the main body belt portion 51 preferably has a thickness in the range of 3 mm to 30 mm, more preferably in the range of 3 mm to 10 mm. And, if the hardness at 25% compression is in the range of 10 N / φ200 to 200 N / φ200 or less, it has appropriate elasticity, and around the waist of the user M without using a hard core material separately. Concentration of applied stress is avoided, and furthermore, due to the moderate softness, the waist belt portion 50 is prevented from floating, and the waist belt portion 50 fits along the curve around the waist according to the body shape of the user M Can be made. As a result, the load applied to the waist of the user M is well-distributed and the load on the waist of the user M is easily dispersed. The weight is not concentrated in a specific part, so the burden on the user M is reduced. It becomes difficult to feel. And even if it is easy to fit along the body shape of the waist of the user M by the solid network structure 100 of a predetermined hardness, the solid network structure 100 is hard to be stuffy because it has air permeability. In particular, it is possible to fit the back of a flat waist that does not bulge compared to the back and abdomen around the waist of the user M, so that the burden on the back of the waist can be reduced even when a piggyback is put on. .
In addition, according to the three-dimensional network structure 100, compared to a conventional cushioning material made of urethane or polyolefin foam, it is light in weight as an equivalent cushioning action, and the weight and carrying burden for the user M who wears it. Can be reduced.

In the case of carrying out the present invention, a core material made of hard urethane or polyolefin-based foam is disposed on the main body belt portion 51, and in order to improve contact with the body, a three-dimensional net-like shape is formed on the user M side. The structure 100 may be provided. Also by this, since the three-dimensional network structure 100 is excellent in air permeability, dampness or the like can be reduced because moisture and heat hardly stay. Further, the body pressure is dispersed by the three-dimensional network structure 100, and the burden on the user M can be reduced.
In addition, the connection of the waist belt portion 50 to the main body portion 10 and the auxiliary support portion 20 may be sewing, or may be a structure that can be attached and detached by an engaging means or the like.

Furthermore, in the baby carrier 1 of the present embodiment, the auxiliary holding portion 20 is sewn to the waist belt portion 50 together with the main body portion 10.
The auxiliary holding portion 20 is disposed on the infant B side of the main body portion 10, and the lower end portion thereof is integrally attached to the waist belt portion 50 together with the main body portion 10. Otherwise, the auxiliary holding portion 20 is separable from the main body portion 10. It is applied to the body of the infant B on the opposite side to the main body 10. When the infant B is held with a face-to-face hug or a forward-facing piggyback, the infant B is applied to the opposite back side, that is, the crotch side or the abdomen side.

  In the figure, the auxiliary holding part 20 is sewn to the waist belt part 50 together with the body part 10 inwardly of the connecting lateral width of the body part 10 and the waist belt part 50, and the other end side of the free end extending upward. It has a substantially trapezoidal shape that is gradually widened toward. The relationship between the auxiliary holding part 20 and the waist belt part 50 is also arranged in a substantially inverted T shape as a whole, and is integrally connected to the waist belt part 50 by sewing only the lower end of the auxiliary holding part 20. The auxiliary holding part 20 is also bendable in a direction perpendicular to the surface direction.

In the present embodiment, the three-dimensional network structure 100 as a cushioning material is also disposed in the auxiliary holding portion 20 applied to the body of the infant B on the side opposite to the main body portion 10.
Also here, the three-dimensional network structure 100 as a cushioning material is covered with an exterior fabric 150 composed of a front fabric 110 and a back fabric 120 to constitute the auxiliary support portion 20. That is, the auxiliary support portion 20 is configured by placing the three-dimensional network structure 100 as a cushioning material in an exterior fabric 150 composed of a front fabric 110 and a back fabric 120 closed in a bag shape. Thereby, the auxiliary support part 20 has predetermined softness | flexibility, flexibility, elasticity, etc., and prevents the infant B's body shape from being forced.
Further, in the auxiliary holding unit 20, a part or all of the outer fabric 150 on the infant B side or the user M side, or both of the outer fabrics 150 on the front and back sides, is used.

  As described above, in the baby carrier 1 of the present embodiment, the auxiliary holding part 20 applied to the body of the infant B on the opposite side to the main body part 10 is provided, and air permeability is provided between the infant B and the user M to be held. By disposing the three-dimensional network structure 100 covered with the cloth having the air, an air passage is formed between the infant B and the user M, and moisture and heat are easily escaped, so that an abnormal heat retention state is not reached. Also, the movement of the infant B or the user M causes a change in volume of the space (air layer) of the three-dimensional network structure 100, so that an air flow is generated, and fresh air is supplied and air with high humidity or heat is generated. Emissions are promoted. Furthermore, even when moisture such as sweat is generated, the three-dimensional network structure 100 has a volume capable of accommodating the moisture, and sweat sweated from the body of the user M or the body of the infant B is quickly absorbed. Since the space of the three-dimensional network structure 100 is continuous, the absorbed moisture is easily dissipated to the outside, and moisture and heat are not easily stored. Therefore, the heat and stuffiness due to the close contact of the user M and the infant B are remarkably reduced, and it is also a countermeasure against sweating and a sweat rash. When the infant B is held, a sticky feeling and a jerky feeling do not occur. Furthermore, even if the body shapes and movements of the infant B and the user M change, there is no sense of incongruity due to the follow-up change of the auxiliary holding unit 20. In addition, since the auxiliary holding part 20 is interposed between the user M and the infant B, it is possible to prevent wrinkles caused by the body temperature of the infant B from entering the clothing of the user M. Moreover, even if the exterior fabric 150 covering the three-dimensional network structure 100 does not have air permeability, if the density of the continuous filaments 101 is increased, air is retained and a heat insulating effect is obtained.

Since the three-dimensional network structure 100 has air permeability and is difficult to retain moisture and heat in this way, the continuous filaments 101 are formed by irregularly meandering entanglements of the continuous filaments 101 made of synthetic resin. Since most of them are loop-like and it is difficult to produce synthetic resin waste, bacteria and molds are difficult to propagate, and permeation of sweat from infant B and user M and odors caused by the propagation of bacteria and molds can be prevented. Furthermore, because it has excellent air permeability and moisture permeability due to continuous space, it has quick-drying properties, so even if you wash it, it dries quickly and there is no risk of bacteria growing before drying. Well, you can keep it clean. In addition, the continuous filaments 101 constituting the three-dimensional network structure 100 are made of synthetic resin, they are irregularly meandering and entangled, and are fused in a meandering state everywhere. Has the strength to withstand washing, and the cushioning properties are unlikely to deteriorate even after repeated washing.
In addition, a comfortable holding feeling can be obtained by appropriate cushioning properties of the three-dimensional network structure 100.

The three-dimensional network structure 100 disposed in the auxiliary holding unit 20 has a thickness of 3 mm or more and 20 mm or less, more preferably 3 mm or more and 10 mm or less. And is flexible and soft enough to be bent in accordance with the body shape of the infant B or the user M, and is less bulky when being carried.
The 25% compression hardness of the three-dimensional network structure 100 disposed in the auxiliary holding part 20 is preferably in the range of 10 N / φ200 or more and 150 N / φ200 or less, more preferably 10 N / φ200 or more, 130 N. / Φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 20 kg / φ150, more preferably 3 kg / φ150 to 10 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 5 kg / φ150 to 25 kg / φ150.
If it is in the above-mentioned range, the solid network structure 100 follows the movements of the infant B and the user M, is familiar with the body shape, and does not feel uncomfortable between the infant B and the user M, such as a sense of incongruity. A feeling can be secured.

  In addition, in the baby carrier 1 of the present embodiment, a predetermined length of cloth having a connecting plug 23 of a buckle with an adjuster at the front end via a connecting cloth 25 at both left and right ends of the auxiliary holding part 20 on the free end side. A pair of left and right connection adjusting portions 22 made of belts are attached, and the connection insertion tool 23 is located near the boundary between the backrest portion 12 and the abutment portion 13 on the left and right sides of the main body portion 10 on the infant B side (outer surface side). A buckle connection receiver 24 corresponding to the engagement is attached, and the left and right side portions on the free end side of the auxiliary holding portion 20 and the main body portion 10 by the connection engagement of the connection insertion tool 23 and the connection receiver 24. A connecting portion 21 having a predetermined length is formed to connect the left and right sides near the boundary between the backrest portion 12 and the abutment portion 13 (see FIG. 6).

  Therefore, in the baby carrier 1 of the present embodiment, the auxiliary holding portion 20 sewn to the waist belt portion 50 together with the main body portion 10 on the infant B side (inner surface side) of the main body portion 10 is connected and adjusted on both right and left sides. The distance between the main body part 10 and the auxiliary holding part 20 by being connected to the main body part 10 by the connection part 21 having a predetermined length formed by the connection engagement of the part 22 and the connection plug 23 and the connection receiver 24 ( Distance) is fixed, and the infant B is positioned in a space formed between the main body 10, the auxiliary holding part 20 and the connection part 21. Thus, the infant B is accommodated between the main body part 10, the auxiliary holding part 20, and the connection part 21, and the main body part 10 is applied to the back side of the infant B in the face-to-face hug and the forward facing piggyback. The auxiliary holding part 20 is assigned to the abdominal side, and the infant B is held by the connecting part 21 so as not to fall sideways. In particular, the leg of the infant B is passed through the annular opening formed between the left and right side edges of the main body 10 and the left and right side edges of the auxiliary holding part 20 below the connection part 21. The situation where the infant B falls from the side of the head rest 11 of the main body 10 due to the bowing of the infant B due to the restriction of the accommodation space of the infant B or the user M's forward bending posture, etc. Can be prevented. Further, even when the position of the baby B is moved with respect to the user M by switching the holding and the piggyback, the infant B can be prevented from falling and the user M can easily switch the holding and the piggyback even if not skilled. And

Furthermore, in the baby carrier 1 of the present embodiment, a pair of left and right shoulder belt portions 40 are sewn to the free end side of the auxiliary holding portion 20.
The one pair of left and right shoulder belt portions 40 are firmly attached to the left and right of the upper end portion on the free end side of the auxiliary holding portion 20 by sewing, and the other end portions are upper portions on the free end side of the auxiliary holding portion 20. It is firmly attached to the left and right side parts of the sewing machine via a connecting fabric 25 by sewing. That is, the shoulder belt portion 40 of the present embodiment is passed in the vertical direction of the auxiliary holding portion 20.

  The pair of left and right shoulder belt portions 40 are directly or indirectly connected to the auxiliary holding portion 20 and the main body portion 10 to receive much of the weight of the infant B, so that the shoulder belt portion 40 can withstand the strength of the user M. As a form in which force (the weight of the infant B) is distributed so as not to overwhelm the user M's body shape even if it is mounted around, it is integrally connected to the upper end on the free end side of the auxiliary holding part 20 and wide in width. A shoulder portion 41 and an adjustment belt portion 42 attached to the other end of the shoulder portion 41 and connected to the left and right side portions of the upper portion of the auxiliary holding portion 20 on the free end side.

  Since the shoulder portion 41 is hung on the left shoulder or the right shoulder of the user M, the shoulder portion 41 is formed of a material having predetermined flexibility, flexibility, etc. This increases the burden on the user M. For example, a cushioning material may be inserted between the outer fabric 110 and the outer fabric 150 of the back fabric 120 so that a part of the back of the user's M shoulder or neck does not cause the infant B to concentrate on the weight. . Also, the shoulder portion 41 can be used as a whole or a part of the exterior fabric 150 with a breathable fabric to prevent moisture such as stuffiness and to reduce discomfort. Furthermore, the hygroscopicity is improved also by forming at least the inner surface side of the user M that touches the shoulder of the user M with a cotton fabric having water absorption.

When practicing the present invention, the outer fabric 150 of the front fabric 110 and the back fabric 120 is composed of a core material made of hard urethane or polyolefin foam as a cushioning material and a soft urethane or polyolefin foam. The shoulder portion 41 can be formed using a cushion material, and the three-dimensional network structure 100 can be used as a cushioning material.
By disposing the three-dimensional network structure 100 as a cushioning material in the shoulder portion 41, it is lighter and more breathable than urethane and polyolefin foams, and can reduce stuffiness and maintain hygiene. It becomes possible.

  That is, since the three-dimensional network structure 100 is excellent in air permeability, air passages are formed, and the volume of the space in the three-dimensional network structure 100 is also changed by the movement of the user M, so that the air flow. Is promoted, moisture and heat are less likely to stay, and stuffiness can be reduced.

  In particular, if the whole or part of the three-dimensional network structure 100 is covered with a breathable fabric, fresh air is taken in and moisture and heat are likely to escape. In addition, due to the high porosity of the three-dimensional network structure 100, the movement of the user M has a volume that can accommodate the moisture generated by the user M such as sweat, but the movement of the user M is three-dimensional network structure. Since the air in the air layer changes in volume in 100 and the air in the air layer is discharged and supplied, the sweat sweated from the body of the user M or the infant B can be quickly absorbed through the breathable fabric, Further, the moisture and heat of the body of the user M and the infant B can be released. Therefore, moisture and heat are not accumulated in the three-dimensional network structure 100, and heat and stuffiness can be reduced, and even when used for a long time, the body temperature is partially prevented from rising abnormally. As a countermeasure, it is possible to reduce discomfort due to the feeling of stuffiness around the shoulder of the user M.

  Needless to say, the fabric having air permeability on both sides of the front fabric 110 and the back fabric 120 constituting the shoulder portion 41, that is, on the front and back surfaces of the shoulder portion 41 with the surface applied to the body of the user M and the opposite surface. Is used, the amount of air flow increases in the thickness direction due to the air permeability of the three-dimensional network structure 100 and the air permeability of the front and back fabrics, thereby further reducing moisture.

  When the three-dimensional network structure 100 is used as a cushioning material for the shoulder portion 41 in this way, the shoulder portion 41 is excellent in air permeability and hardly retains moisture and heat. Thus, bacteria and molds are also difficult to propagate, and the permeation of sweat from the user M and the odor caused by the propagation of bacteria and molds can be prevented. Furthermore, according to the three-dimensional network structure 100, the continuous space is excellent in air permeability and water permeability and moisture permeability, so that it has a quick drying property. Hygiene and cleanliness can be maintained by washing without fear of breeding. Therefore, hygiene characteristics are improved. In addition, the continuous filaments 101 constituting the three-dimensional network structure 100 are made of synthetic resin, they are irregularly meandering and entangled, and are fused in a meandering state everywhere. Has the strength to withstand washing, and the cushioning properties are unlikely to deteriorate even after repeated washing. In addition, even when the baby B is drooling or adhering to the vomit, the moisture dries quickly and can prevent the growth of bacteria and mold.

Furthermore, the continuous linear body 101 is entangled three-dimensionally, and the pressure receiving area around the shoulder and back of the user M is widened by the arrangement of the three-dimensional network structure 100 having a continuous space. It is easy to be dispersed, and the weight felt by the user M can be reduced.
In particular, the three-dimensional network structure 100 disposed in the shoulder portion 41 preferably has a thickness in the range of 3 mm to 30 mm, more preferably in the range of 3 mm to 10 mm. And if the hardness at 25% compression is in the range of 10 N / φ200 to 200 N / φ200 or less, it has appropriate elasticity and around the shoulder of the user M without using a hard core material separately. Concentration of applied stress is avoided, there is little bite, and because there is moderate softness, familiarity is easy and the load applied around the shoulder of the user M is easily dispersed, and the weight does not concentrate in a specific place The burden on the user M is reduced and it becomes difficult to feel discomfort such as pain and stiff shoulders even when worn for a long time. And even if it is easy to fit along the body shape around the shoulder of the user M by the three-dimensional network structure 100 having a predetermined hardness, the three-dimensional network structure 100 is less stuffy because it has air permeability.

In addition, according to the three-dimensional network structure 100, compared to a conventional cushioning material made of urethane or polyolefin foam, it is light in weight as an equivalent cushioning action, and the weight and carrying burden for the user M who wears it. Can be reduced.
When carrying out the present invention, a core material made of hard urethane or polyolefin-based foam is disposed on the shoulder portion 41, and a three-dimensional network structure is formed on the user M side in order to improve contact with the body. It is good also as a structure which arrange | positions the body 100. FIG. Also by this, since the three-dimensional network structure 100 is excellent in air permeability, dampness or the like can be reduced because moisture and heat hardly stay. Further, the body pressure is dispersed by the three-dimensional network structure 100, and the burden on the user M can be reduced.

In the figure, the adjustment belt portion 42 connected to one end portion of the shoulder portion 41 is a belt made of a cloth belt having a predetermined length so that a belt length necessary for mounting around the shoulder of the user M is determined. It is comprised from the part 42a, the adjuster 42b arrange | positioned by the side connected to the shoulder part 41, and the adjuster 42c arrange | positioned by the connection side to the right-and-left side part of the auxiliary | assistant holding | maintenance part 20.
Thus, the adjuster 42b is attached to one end side in the length direction of the belt portion 42a having a predetermined length, and the adjuster 42c is attached to the other end side, so that the belt length can be adjusted, and the shoulder belt portion. The length of 40 can be hung on the shoulder of the user M and adjusted to the length around the shoulder that is turned backward.

  Further, a rotation type buckle connection plug 43 for connecting to the main body 10 is attached to the shoulder portions 41 of the pair of left and right shoulder belt portions 40. The connecting plug 43 is attached to the distal end of the connecting portion 14 projecting from the left and right sides near the boundary between the head support portion 11 and the back support portion 12 on the infant B side (inner surface side) of the main body portion 10. The shoulder belt portion 40 and the main body portion 10 are connected to each other by the coupling insertion tool 43 and the coupling receptacle 44 of the rotary buckle and the connection portion 14 by the coupling engagement with the coupling receptacle 44 of the rotary buckle. Unless the buckle is disengaged, the connection state of the shoulder belt portion 40 and the main body portion 10 is fixed, and the infant B accommodated between the main body portion 10 and the auxiliary support portion 20 can be held.

  Furthermore, the shoulder belt portion 41 of the present embodiment is provided with a shoulder belt adjustment portion 46 that adjusts and holds the distance between the left and right shoulder belt portions 40. The shoulder belt adjusting portion 46 has a buckle connecting plug 46c attached to the tip of an adjustment belt portion 46a of a predetermined length attached to a shoulder hanging portion 41 that is hung on the left shoulder via a belt moving adjuster 48, and a right shoulder. A buckle connecting receiver 46d is attached to the shoulder hanging portion 41 through a belt movable adjuster 48 and a belt cloth 46b so that the connecting plug 46c and the connecting receiver 46d can be engaged with each other. Then, by adjusting the belt length by the adjustment belt portion 46a attached to the adjuster of the buckle connection plug 46c, the connection length of the shoulder belt adjustment portion 46 connecting the left and right shoulder belt portions 40 is adjusted, and the right and left The distance (distance) between the shoulder belt portions 40 can be adjusted. In the case of carrying out the present invention, the adjuster function may be provided for both the connection plug 46c and the connection receiver 46d, or only one of them may be provided, or the adjuster function may be made independent.

  As a result, in the state where the left and right shoulder belt portions 40 are hung on the shoulders, the connection insertion tool 46c of the shoulder belt adjustment portion 46 and the connection receiver 46d are connected and engaged, so that the distance between the left and right shoulder belt portions 40 is increased. It is fixed and can maintain a predetermined distance, and the left and right shoulder belt portions 40 will not come off the shoulder. In addition, by adjusting the belt length by the belt length by the adjustment belt portion 46a attached to the adjuster, a fulcrum that supports the weight of the infant B is used according to the body shape, usability, preference, how to hold the infant B, etc. It can be adjusted to a position with less burden on the person M. Therefore, even a person with a stiff shoulder can reduce the burden on the shoulder.

In addition, the shoulder belt adjustment portion 46 of the present embodiment is slid through a belt movable adjuster 48 having belt passing portions in four directions with respect to a slide belt 47 disposed along the surface of the shoulder portion 41. The shoulder belt adjusting portion 46 is movable on the surface of the shoulder portion 41.
Therefore, even when the pair of left and right shoulder belt portions 40 are hung on the shoulder of the user M, the position of the shoulder belt adjustment portion 46 is moved to connect the connection insertion tool 46c and the connection receptacle 46d of the shoulder belt adjustment portion 46. The position of engagement can be adjusted to an optimum position that is easy for the user M to operate the coupling engagement. Further, the fulcrum supporting the weight of the infant B can be adjusted to a position with less burden on the user M according to the body shape, convenience, preference, how to hold the infant B, and the like. This also reduces the burden on the shoulder for those who are stiff.
Incidentally, when the present invention is carried out, the means for adjusting or fixing the distance (distance) between the left and right shoulder belt portions 40 is limited to that by connection of the buckle or sliding of the buckle. There is nothing. Moreover, these functions may be performed by one member or may be performed by separate members.

  In the figure, the baby B is accidentally engaged with the buckle by covering the connecting plug 43 attached to the shoulder 41 of the shoulder belt 40 with the covering cover 45 attached to the shoulder 41. It prevents it from being released. Further, the buckle formed of plastic is prevented from being deteriorated by ultraviolet rays or the like. Furthermore, even if the lip of the infant B hits the shoulder portion 41 and thereby the lips of the infant B are stimulated and the shoulder belt portion 40 may be licked, by covering with the covering cover 45 attached to the shoulder portion 41, The buckle will not injure infant B's lips and tongue.

  In the baby carrier 1 of the present embodiment, the baby carrier 1 is further provided between the main body 10 and the auxiliary holding part 20 and is arranged between the main body 10 and the auxiliary holding part 20 by adjusting the length to be folded in the length direction. It has a positioning seat 30 that allows the depth of the child 10 to be freely adjusted and positions the sinking depth of the buttocks of the infant 10. Since the positioning seat portion 30 is also directly applied to the body of the infant B, it is formed of a material having predetermined flexibility and flexibility.

  In the figure, the positioning seat portion 30 is integrally extended from the vicinity of the boundary between the backrest portion 12 and the abutment portion 13 of the main body portion 10 and gradually narrowed toward the center side, and then the other end on the opposite side. The second abutment part 31 applied to the buttocks of the infant 10 when holding the infant B with a face-to-face holding or a front-facing piggyback, and a constant from the second buttocks abutment part 31 The length adjustment part 32 is formed by extending integrally with the width and allowing the length dimension to be adjusted.

  The length adjusting portion 32 integrally formed from the second abutment portion 31 is formed with a constant lateral width, and its length dimension is on the back side opposite to the opposing side of the main body portion 10 and the auxiliary holding portion 20. A pair of female sides 33a and a male side 33b of a slide-type fastener 33 as an adjustment tool for making adjustment possible, and the pair of female sides 33a and the male side 33b of the slide-type fastener 33 have a predetermined distance. Installed, apart.

  Therefore, the length between the female side 33a and the male side 33b is closed by closing the pair of the female side 33a and the male side 33b of the slide-type fastener 33 that are separated by a predetermined distance in the length adjusting unit 32. The length of the positioning pedestal 30 that is fixed in the folded state and connects between the main body 10 and the auxiliary holder 20 is shortened. On the other hand, when the engagement of the pair of female side 33a and male side 33b of the sliding fastener 33 is released, the folding is unfolded, and the positioning pedestal portion 30 has the original length and the main body portion 10 and the auxiliary holding portion 20. Connect between.

  Thus, when the infant B is disposed between the main body 10 and the auxiliary holding portion 20, a pair of female sides 33a of the sliding fastener 33 of the positioning base portion 30 that passes between the main body 10 and the auxiliary holding portion 20 is provided. In the state where the male side 33b is not engaged, the length of the positioning pedestal 30 disposed between the main body 10 and the auxiliary holding portion 20 is long. The infant B, which is housed between the main body 10 and the auxiliary holding part 20 and has the buttocks received by the positioning pedestal 30, has a deepened sinking depth. That is, the buttocks of the infant B are positioned at a low position.

  On the other hand, in the engagement state in which the pair of female sides 33a and the male side 33b of the sliding fastener 33 of the positioning base 30 passing between the main body 10 and the auxiliary holding unit 20 are closed together, a pair of female sides Since the length between 33a and the male side 33b is folded and the connection length of the positioning pedestal portion 30 connecting the main body portion 10 and the auxiliary holding portion 20 is shortened, the positioning pedestal portion 30 causes the main body portion to be shortened. 10 and the auxiliary holding part 20 is raised in depth, and the infant B, which is accommodated between the main body part 10 and the auxiliary holding part 20 and is received by the positioning pedestal 30, has a shallow sinking depth. Become. In other words, the buttocks of the infant B are positioned at a high position.

  Therefore, according to the baby carrier 1 of the present embodiment, when the infant B to be held is low in height, the slide of the positioning pedestal 30 disposed between the main body 10 and the auxiliary holder 20 is arranged. By engaging the pair of female side 33a and male side 33b of the type fastener 33 and shortening the connection length between the main body part 10 and the auxiliary holding part 20 in the positioning pedestal part 30, Since the sink is positioned at a high position, even if the infant B to be held is short, the head of the infant B does not become a low position in the positional relationship between the main body 10 and the infant B, and the head of the infant B is the head. The baby B is stably placed in a comfortable posture with less burden, without being placed in the body 11 and the body 20 and the auxiliary holder 20 so that the body of the baby B sinks.

  When the infant B to be held is tall, that is, when the infant B becomes large due to growth, the pair of female side 33a and male side 33b of the sliding fastener 33 is disengaged, By developing the connection length between the main body part 10 and the auxiliary holding part 20 to the original length in the positioning pedestal part 30, the sinking of the buttocks of the infant B is positioned at a low position. On the other hand, the head support part 11, the back support part 12, and the buttocks support part 13 of the main body part 10 are applied at appropriate positions, and the infant B is stably held in a comfortable posture with less burden.

Further, in the case where the infant B is mounted on the back side of the user M facing forward in the same direction as the user M, the length of the positioning pedestal 30 that connects between the main body 10 and the auxiliary holding unit 20 is shortened. Since the position of the buttocks of the infant B can be increased, the position of the infant B can be held at a position farther from the position of the waist of the user M, so that the spine of the user M and the spine of the infant B are repelled. As a result, the shape of the curved spine line of the infant B tends to follow the shape of the curved spine line of the user M, and the infant B easily adheres to the user M. Therefore, it is possible for the user M and the infant B to hold comfortably with a comfortable posture. In particular, the user M carrying the infant B is less likely to feel the weight of the infant B than the baby and can easily hold it. In addition, since the infant B easily comes into close contact with the user M, the infant B is unlikely to be warped backward.
Even when the buttocks of the infant B are landed on the positioning pedestal portion 30 whose original length is between the main body portion 10 and the auxiliary holding portion 20 and is placed at a low position, the auxiliary holding portion 20 and the main body portion 10 are also disposed. Are connected by the connection part 21 and the leg of the infant B is passed through the ring formed by the auxiliary holding part 20, the main body part 10 and the connection part 21, so that the infant B can be prevented from falling due to warping.

  Since the positioning seat portion 30 is also applied to the body of the infant B, it is formed of a material having predetermined flexibility, flexibility, and the like. For example, the exterior fabric 150 of the front fabric 110 and the back fabric 120 is used. By forming a cushioning material between the two, the baby B can comfortably hold and sit comfortably. For example, in the second abutment portion 31 applied to the buttocks of the infant 10, the three-dimensional network structure 100 is disposed between the front fabric 110 and the back fabric 120 constituting the infant 10, so that the infant B The buttocks can be received softly, the depression of the buttocks can be facilitated, the center of gravity position of the infant B can be stabilized and the holding stability can be enhanced. And even when hold | maintaining for a long time, the fitting property to the buttocks of the infant B is high, and it becomes comfortable seating by the pressure applied to the buttocks being dispersed, and the burden on the buttocks of the infant B is reduced.

The 25% compression hardness of the three-dimensional network structure 100 disposed in the positioning seat 30 is preferably in the range of 10 N / φ200 or more and 150 N / φ200 or less, more preferably 10 N / φ200 or more, 130 N. / Φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 20 kg / φ150, more preferably 3 kg / φ150 to 10 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 5 kg / φ150 to 25 kg / φ150.
If it is within the above range, the lower part of the buttocks of the infant B can be easily lowered, the center of gravity of the buttocks can be stabilized to prevent the position shift, thereby obtaining a stable sinking of the infant B and improving the holding stability. It is possible to hold in a comfortable posture with less burden on M and infant B. Moreover, even if it touches the leg of the infant B, it follows it, and the movement of the leg of the infant B is difficult to be restricted. In particular, even when holding an infant B of a young age before the neck is set, the knee of the infant B is easily bent down, so that the knee is bent at a position higher than the position of the buttocks of the infant B, and an M-shaped spread leg is formed. In a natural open leg posture, the center of gravity of the infant B is not on the leg side but on the buttocks, and the body shape of the infant B can be held with a low burden.

  In the baby carrier 1 according to the present embodiment, the portion applied to the buttocks of the body of the infant B on the side opposite to the infant B as the holding section applied to the body of the infant B is the abutment portion 13 of the main body 10 and the positioning seat portion. 30 second latching portions 31, but either the latching portion 13 or the second latching portion 31, or both the latching portion 13 and the second latching portion 31 have a three-dimensional network structure. By disposing 100, the buttocks of the infant B easily fall down, the center of gravity of the infant B is stabilized, and the holding stability is improved. Moreover, the pressure applied to the buttocks of the infant B is easily dispersed, the sitting comfort is improved, and the burden on the infant B is reduced. Of course, the sitting comfort of the infant B is improved by providing the three-dimensional network structure 100 also in the length adjusting unit 32. However, in the baby carrier 1 of the present embodiment, in the state where the length adjustment unit 32 is lengthened, it overlaps with the auxiliary holding unit 20 and is applied to the crotch side of the infant B's body. In the case where the three-dimensional network structure 100 is disposed on the positioning seat portion 30, only a portion that is applied to the buttocks of the infant B may be provided in consideration of the bulkiness of the crotch side of the infant B, the unevenness, and the like. Of course, when the three-dimensional network structure 100 is disposed on the positioning seat 30 according to the purpose of the baby carrier 1 or the like, it is possible to provide a partial arrangement of only the portion applied to the crotch side of the infant B. .

In particular, since the three-dimensional network structure 100 has high air permeability, even if it is in close contact with the buttocks of the infant B, it is difficult to get stuffy, and diaper rashes are hardly caused. In addition, as described above, hygienic characteristics are also improved.
And in this positioning seat part 30, since it will be applied directly to the infant B, the moisture, such as stuffiness, is prevented by using the cloth which has air permeability for the exterior cloth for the whole or a part. And discomfort can be reduced. Also, the hygroscopicity is improved by forming at least the upper surface side (surface side) in contact with the infant B with a cotton fabric having water absorption.

Note that the length adjustment unit 32 that can be folded is also flexible and flexible enough to be folded, and elastic and buffered so that the infant B does not feel uncomfortable or uncomfortable. Alternatively, the three-dimensional network structure 100 may be disposed with a small thickness.
The positioning seat 30 is formed of a material having a low elasticity that does not stretch or elastically deform due to an elastic force acting in the direction of gravity when an external force receiving the weight of the infant 10 is applied.

  As described above, the baby carrier 1 according to the present embodiment includes the main body 10, the auxiliary holding unit 20, and the positioning as a holding unit that holds the baby B by holding or holding the baby B by the body of the baby B. In the baby carrier 1 having the portion 30, the main body portion 10, the auxiliary holding portion 20, and the positioning portion 30 as a holding portion for holding the infant B are configured by an exterior fabric 150 and a cushioning material wrapped in the exterior fabric 150. The material is a continuous three-dimensional network 101 made of synthetic resin that is irregularly meandered and entangled, and is fused in a meandering state, and the space between the continuous filaments 101 communicates with each other. The structure 100 is formed.

  That is, the baby carrier 1 according to the present embodiment is disposed on the main body 10, the auxiliary holding part 20, and the positioning part 30 as a holding part that is applied to the body of the infant B and holds the infant B. The cushioning material placed in the exterior fabric 150 made up of one front fabric 110 and the other back fabric 120 opposite the front fabric constituting the main body portion 10, the auxiliary holding portion 20, and the positioning portion 30 is made of a synthetic resin. The continuous filaments 101 are irregularly meandering and intertwined, and are fused in a meandering state, and the space between the continuous filaments 101 communicates with each other so as to have a breathable three-dimensional network structure. 100.

Therefore, according to the baby carrier 1 according to the present embodiment, when an external force is applied due to the arrangement of the three-dimensional network structure 100, the curvature of curvature of the curved continuous filament 101 constituting the same changes, When the space between the continuous filaments 101 is deformed and the external force is released, the continuous filaments 101 return to the original curvature, and the cushioning property (elasticity) for restoring the space is excellent. In particular, since the continuous filaments 101 are fused together, the pressure receiving area is wide, and when an external force is applied, the entire three-dimensional network structure 100 is deformed, and the user M and infants with a small sinking depth. Supports the body of B, disperses the pressure applied to the body evenly, and has a cushioning property with little bottom feeling even if the thickness is thin.
Moreover, the space between the continuous filaments 101 constituting the three-dimensional network structure 100 communicates with each other, and the air permeability is excellent. Therefore, moisture and heat hardly stay, heat can be reduced, and the occurrence of stuffiness can be prevented.
Therefore, a comfortable holding feeling for the infant B is obtained, and the burden on the infant B is reduced even when used for a long time.

  And since moisture and heat do not easily stay in the three-dimensional network structure 100 in this way, it is difficult for bacteria, fungi, etc. to propagate, and furthermore, the space between the continuous striatal bodies 101 communicates with each other so that air permeability and water permeability can be obtained. And the moisture content dries quickly, and the continuous filaments 101 constituting the three-dimensional network structure 100 are made of a synthetic resin. They are irregularly meandered and intertwined, and in a meandering state everywhere. Since it is fused to each other, it has strength to withstand repeated washing, and characteristics such as cushioning properties are unlikely to deteriorate even after repeated washing. Therefore, hygiene and cleanliness can be maintained.

  In particular, when a part or all of the exterior fabric 150 including the cushioning material made of the three-dimensional network structure 100 is formed into mesh-like fibers that allow air to enter and exit, the continuous filaments constituting the three-dimensional network structure 100 are formed. By supplying fresh air to the space between the bodies 101 and discharging the air held in the space between the continuous filaments 101, moisture and heat from the infant B and the user M can easily escape. A partial increase in body temperature can be prevented, and stuffiness can be further prevented. In addition, hygiene characteristics are improved. Furthermore, by making the fabric into a mesh structure having a mesh structure or a plurality of ventilation holes, flexibility and stretchability are also increased, and the fit and familiarity with the body shape and movement of the infant B and the user M are improved. In addition, since the weight is reduced, the burden on the user M is also reduced.

In this way, according to the baby carrier 1 according to the present embodiment, it is cushioned, but it is difficult to stuffy and can be held comfortably, and even if the baby B is held for a long time, the baby B can be less tired. In addition, hygienic characteristics are improved.
Further, even if the head hood is used, moisture and heat are difficult to be stored, which is advantageous for laying on the bed, and the infant B who is sleeping is prevented from sweating excessively, and a comfortable sleeping environment can be created.
In addition, since the three-dimensional network structure 100 has high air permeability and moisture and heat are not easily trapped in the cushioning material, the heat is reduced and the stuffiness is reduced. Thus, affected areas such as sweat rash and atopic dermatitis can be kept hygienically, deterioration can be prevented, and their onset can be prevented.
In addition, because the three-dimensional network structure 100 communicates with the gap, moisture can not be accumulated even when sprayed with deodorizing alcohol or a disinfecting spray, so that cleanliness and hygiene can be maintained.

  And in the holding | maintenance part which is applied to the infant's B body and hold | maintains the infant B, the three-dimensional network structure 10 is arrange | positioned in the main-body part 10 applied to the infant's B body on the opposite side to the user M side. Thus, compression, shaking and impact are alleviated by the three-dimensional network structure 100 which is supported on a large area with respect to the body of the infant B, and the posture of the infant B is not burdened even when used for a long time. However, it is difficult for moisture and heat such as sweat from the infant B to accumulate in the three-dimensional network structure 100, so that the heat and stuffiness of the infant B can be effectively prevented, and the comfort for the infant B becomes higher. .

Here, in the main body 10 as a holding unit that holds the infant B by being applied to the body of the infant B, the body B is applied to the head of the body of the infant B when holding the infant B with a face-to-face holding or a forward facing piggyback. If the hardness and repulsive force of the three-dimensional network structure 100 disposed on the head support 11 as a part is too small, the neck and head of the infant B may sway, or the head may hang backwards during sleep, etc. Therefore, a separate core material is required. On the other hand, if it is too large, the hit on the body becomes stronger.
According to the experimental study by the present inventors, the hardness at the time of 25% compression (stress when the three-dimensional network structure 100 is compressed to 75% with a 200 mm diameter circular compression plate and then compressed again by 25%). 10 N / φ200 or more and 180 N / φ200 or less, more preferably 10 N / φ200 or more and 130 N / φ200 or less, and a three-dimensional network structure 100 having a thickness of 20 mm is formed into a circular compression plate having a diameter of 150 mm. The load is applied to 5 mm (compression rate 25%), and the applied force (repulsive force) when submerged 10 mm (compression rate 50%).

The head and neck of the infant B can be supported and the impact can be reduced.

That is, the three-dimensional network structure 100 disposed at the portion applied to the head of the infant B in the holding portion that holds the infant B by being applied to the body of the infant B is 10N / φ200 or more and 180N / φ200 or less. The hardness at 25% compression within the range is preferable, and the hardness at 25% compression within the range of 10 N / φ200 to 130 N / φ200 is more preferable.
25% of the three-dimensional network structure 100 disposed at the portion of the holding portion that is applied to the head of the body of the infant B when facing the user M with the ventral side of the infant B facing the user M or facing forward. If the hardness at the time of compression is in the range of 10 N / φ200 or more and 180 N / φ200 or less, the head and neck of the infant B can be supported and impact can be reduced without providing a separate hard core.

In addition, the three-dimensional network structure 100 disposed at a portion applied to the head of the infant B in the holding portion that holds the infant B by being applied to the body of the infant B is 150 mm in thickness of the three-dimensional network structure 100 having a thickness of 20 mm. When the load is applied to a circular compression plate with a diameter of 5 mm (compression rate 25%) and the applied force (repulsive force) is submerged, the repulsive force during compression is 25% (push-in amount 5 mm). Is preferably in the range of 3 kg / φ150 or more and 15 kg / φ150 or less, and more preferably in the range of 4 kg / φ150 or more and 10 kg / φ150 or less.
25% of the three-dimensional network structure 100 disposed at the portion of the holding portion that is applied to the head of the body of the infant B when facing the user M with the ventral side of the infant B facing the user M or facing forward. (Pushing amount 5 mm) If the repulsive force during compression is in the range of 3 kg / φ150 or more and 15 kg / φ150 or less, the head and neck of the infant B can be supported and impacted without providing a separate hard core. Can be relaxed.

Then, the three-dimensional network structure 100 disposed in the portion applied to the infant B's body and disposed at the portion applied to the head of the infant B in the holding portion that holds the infant B is 50. %) When the force (repulsive force) applied when submerged is measured, the repulsive force at the time of compression is preferably 5 kg / φ150 or more and 30 kg / φ150 or less, preferably 10 kg / φ150. As described above, the range of 30 kg / φ150 or less is more preferable.
25% of the three-dimensional network structure 100 disposed at the portion of the holding portion that is applied to the head of the body of the infant B when facing the user M with the ventral side of the infant B facing the user M or facing forward. (Pushing amount 5 mm) If the repulsive force at the time of compression is in the range of 5 kg / φ150 or more and 30 kg / φ150 or less, the head and neck of the infant B can be supported and shocked without providing a separate hard core. Can be relaxed.

Moreover, in the main body 10 as a holding portion that holds the infant B by being applied to the body of the infant B, when the infant B is held with a face-to-face hug or a forward-facing piggyback, it is applied to the back from the waist of the body of the infant B. If the hardness and the repulsive force of the three-dimensional network structure 100 disposed on the backrest portion 12 as a part to be bent are too small, the effect of preventing warping during a piggyback is small. Become.
According to the experimental study by the present inventors, the hardness at the time of 25% compression (the stress when the solid network structure 100 is compressed by 75% with a 200 mm diameter circular compression plate and then compressed again by 25%) 10N / φ200 or more and 180N / φ200 or less, more preferably 10N / φ200 or more and 150N / φ200 or less, and the solid network structure 100 having a thickness of 20 mm is formed into a circular compression plate having a diameter of 150 mm. When the load is applied and 5mm (compression rate 25%) or 10mm (compression rate 50%), the applied force (repulsive force) when submerged is measured. When the compression rate is 25% (push-in amount 5mm) In the range of 3 kg / φ150 or more and 20 kg / φ150 or less, more preferably in the range of 3 kg / φ150 or more and 15 kg / φ150 or less, and a compression rate of 50% (push amount 10 m) m), the repulsive force is preferably in the range of 5 kg / φ150 or more and 30 kg / φ150 or less, more preferably in the range of 15 kg / φ150 or more and 30 kg / φ150 or less. The back of the infant B can be supported from the waist, and can be prevented from turning over when riding, and the holding posture can be maintained with less depression and less burden.

However, when carrying out the present invention, the auxiliary holding part 20 is not necessarily required and can be omitted.

That is, when carrying out the present invention, the holding part for holding the infant M may be only the main body part 10 applied to the body of the infant B on the side opposite to the user M holding the infant B, or the infant B The body 10 applied to the body of the infant B on the side opposite to the user M side holding the child and the auxiliary holding part 20 applied to the body of the infant B on the side opposite to the body 10 side, that is, the user M side. May have.
When the holding part that holds the infant M is configured only by the main body part 10, the three-dimensional network structure 100 as a cushioning material is disposed in the main body part 10, but the holding part that holds the infant M. When the part is constituted by the main body part 10 and the auxiliary holding part 20, the three-dimensional network structure 100 may be arranged on both the main body part 10 and the auxiliary holding part 20, or the arrangement of the three-dimensional network structure 100 Only one of the main body part 10 and the auxiliary holding part 20 may be provided.

  Further, when the present invention is implemented, the waist belt portion 50 is not necessarily required and can be omitted, and an opening through which the leg of the infant B is put out in a holding form in which the infant B does not fall is formed. However, it is also possible to support the weight of the infant B with only the left and right shoulder belt portions 40 and hold or carry the infant B.

  In the figure, the shoulder belt portion 40 is connected to the auxiliary holding portion 20. However, when the present invention is carried out, the shoulder belt portion 40 is provided only on the main body portion 10 as long as the infant B can be held. May be connected, or the shoulder belt portion 40 may be connected to the main body portion 10 and the auxiliary holding portion 20. In any case, it may be configured to be connected to a position that does not interfere with the body of the infant B and to form a ring through which the shoulder of the user M is passed.

Moreover, in the said embodiment, although it was description about the baby carrier 1 of the form which hold | maintains the infant B in the vertical holding, when implementing this invention, it has the holding form of the side holding the baby B laid down. Berry carrier 1 may be used. It should be noted that the shoulder belt portion 40 is usually worn by sashing on the side. Moreover, the structure which enables the holding form of both vertical holding and horizontal holding may be sufficient.
In particular, when the three-dimensional network structure 100 is disposed in the holding portion that applies the back side of the infant B when holding it sideways, the back side of the body of the infant B laid sideways is supported from multiple directions, The pressure dispersion effect is high, vibrations and the like can be absorbed, and the burden on the infant B can be reduced even when held for a long time.

Furthermore, when the present invention is implemented, the three-dimensional network structure 100 is covered with the exterior fabric 150, but the three-dimensional network structure 100 may be configured to be removable from the exterior fabric 150. If the three-dimensional network structure 100 can be freely attached and detached according to the holding form and growth size of the infant B, a comfortable holding posture for the infant B can be pursued. In addition, only the three-dimensional network structure 100 can be washed or dried quickly, so that hygiene can be easily maintained and convenience is enhanced. In particular, when holding an infant B of a young age whose posture is unstable, the arrangement of the three-dimensional network structure 100 having the above-described hardness and repulsive force provides high protection and buffering effects for the infant B, and the body of the infant B Although the burden on the child can be reduced, a good holding posture can be easily maintained even when the three-dimensional network structure 100 is removed when the baby B that has grown and enlarged is held, and an appropriate movement of the baby B can be released. .
In addition, for example, by enclosing the three-dimensional network structure 100 with a breathable fabric made of mesh fibers in summer, air can be easily taken in and out by taking in fresh air, while in winter, breathable Thermal insulation can be obtained by coating the three-dimensional network structure 100 with a fabric without any other material.

On the other hand, the three-dimensional network structure 100 may be fixed to the exterior fabric 150 by sewing or the like. As a result, it is possible to prevent bias due to the movement of the three-dimensional network structure 100 in the exterior fabric 150, and the three-dimensional network structure 100 is maintained at an appropriate position even with a small front and back area, and effectively exhibits a buffering effect and the like. Therefore, the amount of the three-dimensional network structure 100 used can be suppressed, and the cost can be reduced.
In the case of carrying out the present invention, the main body 10 also has a structure in which the core material is appropriately disposed and the three-dimensional network structure 100 is disposed on the infant B side in order to improve the contact with the body. Also good. Also by this, since the three-dimensional network structure 100 is excellent in air permeability, dampness or the like can be reduced because moisture and heat hardly stay. Further, the body pressure is dispersed by the three-dimensional network structure 100, and the burden on the infant B can be reduced.

  TECHNICAL FIELD The present invention relates to a baby carrier (childcare band) that assists and carries an infant when it is carried or carried, and in particular, a baby having improved comfort and hygiene characteristics during holding. It is about career.

When holding an infant using a baby carrier when holding or carrying a baby, a part of the baby carrier will be applied to a part of the infant's body. Since the body temperature is high due to the immature adjustment function and the same holding posture is maintained for a long time, the user who is in close contact with the baby and the infant during use of the baby carrier has a high body temperature and is likely to sweat. Moisture such as stuffiness is also likely to occur.
In particular, in the hug that holds the infant vertically on the chest abdomen side of the user's body and the piggyback that holds the infant vertically on the user's back side, the holding form that the infant is in close contact with the user Therefore, heat and stuffiness are likely to occur due to the mutual transmission of heat between the user and the infant, and the user and the infant are uncomfortable, and the rash and diaper rash may occur when the user and the infant are used for a long time. In addition, when a so-called head hood that covers and supports the infant's rear head is used, the entire body of the infant is wrapped when the head hood is used, so that the infant is more likely to sweat. Especially for younger infants with sensitive skin and unstable posture, it is necessary to maintain a high degree of adhesion with the user in order to maintain stable and less burdensome, with less glare on the body, The effects of heat and stuffiness are significant.

  In addition, due to the increase in humidity and temperature due to stuffiness when the baby is held by the baby carrier in this way, sweat sweated from the user or infant's body due to an increase in the body temperature of the user or infant adheres to the baby carrier. By doing so, it becomes a hotbed of bacteria, and there is a risk of causing the growth of bacteria and generation of unpleasant odor in the baby carrier. In particular, the frequency of use of baby carriers has been increasing in the present age when the nuclear family is becoming more advanced, and furthermore, the development of baby carriers that can be used from the neonatal period has made it possible to use them for a long time. With regard to baby carriers that touch sensitive skin, an increasing number of users are concerned about cleanliness and hygiene.

  On the other hand, if the baby carrier pursues comfort, such as ease of pressure, shaking, shock, and stability of the infant's posture and holding, it is necessary to improve cushioning at the part applied to the infant's back and abdomen. Therefore, conventionally, as described in Patent Document 1, for example, a soft urethane foam, a polyolefin-based foam, or the like having a low resilience is used for a portion applied to the infant's back side. Also, rigid foamed urethane foam, polyolefin foam, etc. may be used as the core material to prevent the sinking of the upper body from the lower back and keep the infant's body in a stable support state. is there. Furthermore, in order to reduce the load on the user, urethane foam, polyolefin foam, or the like may be used for a shoulder belt or a waist belt worn on the user.

JP 2006-130016 A

  However, such urethane materials and polyolefin foams are basically inferior in breathability and moisture permeability, and heat and moisture that have entered the inside are difficult to escape to the outside. End up. In particular, the closed-cell foaming type has a heat storage property, which further promotes thickness and stuffiness. In addition, urethane materials and polyolefin foams may be damaged, deformed, or sag by washing, and it takes time to dry. I am worried.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a baby carrier that has cushioning properties but is resistant to stuffiness and can be held comfortably and has improved hygiene characteristics.

  The baby carrier of the invention of claim 1 is applied to the infant's body and the continuous linear body made of a synthetic resin is irregularly meandered and intertwined as a cushioning material in the holding part for holding the infant, and In the meandering state, it is fused everywhere, and the space between the continuous filaments communicates to have a three-dimensional network structure having air permeability.

  Here, the holding unit is a member that is applied to the infant's body and protects the infant, and may be used depending on the purpose of the baby carrier (holding mode such as a cuddle or piggyback, age of the target infant), type, and the like. Some members are applied only to the other members, while other members may be provided to the infants and other users (parents) who hold the infants and support them. In other words, some members are applied only to the infant's non-user side, while others include both a member applied to the infant's anti-user side and a member applied to the infant's user side. In addition, the use of the three-dimensional network structure may be used only for a member applied to the infant's non-user side, or may be used only for a member applied to the infant's user side. It may be used for both a member applied to the side opposite to the user and a member applied to the user side of the infant.

The cushioning material is not limited to its purpose as long as it has a buffering function. For example, the cushioning material (elasticity) is enhanced, the contact with the body is improved, and the supporting force is enhanced. And those arranged for the purpose of improving fit and the like.
The three-dimensional network structure has a cushioning property in which a continuous linear body made of a synthetic resin meanders irregularly and is fused in the meandering state. That is, even if the space between the continuous filaments is deformed by an external force, the space is restored when the external force is released. And the space between continuous filaments is connecting, and it has air permeability by the high porosity of 70 to 98% normally. The three-dimensional network structure is wrapped in an exterior fabric to constitute the holding unit.
The manufacturing technique of this three-dimensional network structure is well-known in the patent gazette etc. which are mentioned later. This three-dimensional network structure is arranged so that the elastic change in the thickness direction in the vertical direction is large with respect to the front and back surfaces of the holding portion facing each other, and the expansion and contraction in the direction parallel to the front and back surfaces is small. The distinction between the front surface and the back surface is not particularly limited. As described above, the elasticity of the three-dimensional network structure can be arbitrarily selected, so that the number of types of synthetic resins to be selected for the regeneration process is small. The elasticity of the three-dimensional network structure changes when the infant is held, depending on the holding force or the movement of the infant and breathes.
The holding portion is configured by the three-dimensional network structure in which a portion applied to the anti-user side of the infant's body is wrapped in the outer fabric made of a front fabric and a back fabric facing the front fabric. It is what.
The part of the infant that is placed on the opposite side of the user that holds or rides the infant is applied to the infant's back when the infant is held face-to-face or carried forward.
The mesh-like fiber in which part or all of the exterior fabric in which the three-dimensional network structure is placed allows air to enter and exit may be used as long as it allows air to flow. It is not limited to using a low fabric or the fabric being knitted (net-like). For example, air can be circulated by forming multiple through holes (openings) of a predetermined shape in the fabric. It may be.
Preferably, at least a part or all of the surface applied to the infant's body is formed of mesh fibers.

The baby carrier of the invention of claim 2 is applied to an infant's body and has a continuous linear body made of a synthetic resin irregularly meandering and entangled as a cushioning material in a holding part for holding the infant. In the meandering state, it is fused everywhere, and the space between the continuous filaments communicates to have a three-dimensional network structure having air permeability.

Here, the holding unit is a member that is applied to the infant's body and protects the infant, and may be used depending on the purpose of the baby carrier (holding mode such as a cuddle or piggyback, age of the target infant), type, and the like. Some members are applied only to the other members, while other members may be provided to the infants and other users (parents) who hold the infants and support them. In other words, some members are applied only to the infant's non-user side, while others include both a member applied to the infant's anti-user side and a member applied to the infant's user side. In addition, the use of the three-dimensional network structure may be used only for a member applied to the infant's non-user side, or may be used only for a member applied to the infant's user side. It may be used for both a member applied to the side opposite to the user and a member applied to the user side of the infant.

The cushioning material is not limited to its purpose as long as it has a buffering function. For example, the cushioning material (elasticity) is enhanced, the contact with the body is improved, and the supporting force is enhanced. And those arranged for the purpose of improving fit and the like.
The three-dimensional network structure has a cushioning property in which a continuous linear body made of a synthetic resin meanders irregularly and is fused in the meandering state. That is, even if the space between the continuous filaments is deformed by an external force, the space is restored when the external force is released. And the space between continuous filaments is connecting, and it has air permeability by the high porosity of 70 to 98% normally. The three-dimensional network structure is wrapped in an exterior fabric to constitute the holding unit.
The manufacturing technique of this three-dimensional network structure is well-known in the patent gazette mentioned later. This three-dimensional network structure is arranged so that the elastic change in the thickness direction in the vertical direction is large with respect to the front and back surfaces of the holding portion facing each other, and the expansion and contraction in the direction parallel to the front and back surfaces is small. The distinction between the front surface and the back surface is not particularly limited. As described above, the elasticity of the three-dimensional network structure can be arbitrarily selected, so that the number of types of synthetic resins to be selected for the regeneration process is small. The elasticity of the three-dimensional network structure changes when the infant is held, depending on the holding force or the movement of the infant and breathes.

The holding portion is configured by the three-dimensional network structure in which a part applied to the user side of the infant's body is wrapped in the outer fabric made of a front fabric and a back fabric facing the front fabric. Is.
The part of the user who holds or rides the infant on the side of the infant is disposed between the infant and the user who supports the infant, and when carrying the infant facing or facing forward, It applies to the crotch side and the abdomen side opposite to the dorsal side of the infant's body.
The mesh-like fiber in which part or all of the exterior fabric in which the three-dimensional network structure is placed allows air to enter and exit may be used as long as it allows air to flow. It is not limited to using a low fabric or the fabric being knitted (net-like). For example, air can be circulated by forming multiple through holes (openings) of a predetermined shape in the fabric. It may be.
Preferably, at least a part or all of the surface applied to the infant's body is formed of mesh fibers.

According to the baby carrier of the first aspect of the present invention, the buffer material disposed on the holding portion that holds the infant by being applied to the infant's body, the continuous linear body made of synthetic resin meanders irregularly. In addition, they are intertwined, and are fused in various places in the meandering state, and the space between the continuous filaments communicates to form a three-dimensional network structure having air permeability. According to this three-dimensional network structure, when an external force is applied, the curvature of the curved continuous filaments constituting the same changes, the space between the continuous filaments is deformed, and the external force is released, The striatum returns to its original curvature, and can express the cushioning properties (elasticity) that recover the space.
Moreover, the space between the continuous filaments constituting the three-dimensional network structure is communicated, and the air permeability is excellent.In particular, the space is also deformed by the movement of infants and users, and the flow of air is generated. Heat hardly stays and can prevent the occurrence of stuffiness.
Therefore, comfortable holding for the infant is obtained, and the burden on the infant is reduced even when used for a long time.

And, since moisture and heat hardly stay in the three-dimensional network structure in this way, it is difficult for bacteria and fungi to propagate, and further, the space between the continuous striatal bodies communicates with each other to make air permeability and moisture permeability. It is excellent in that it dries quickly, and the continuous filaments that make up the three-dimensional network structure are made of synthetic resin. They are irregularly meandered and intertwined, and are fused in a meandering state everywhere. Therefore, it has the strength to withstand repeated washing, and characteristics such as cushioning properties are unlikely to deteriorate even after repeated washing. Therefore, hygiene and cleanliness can be maintained.
In this way, a baby carrier that has cushioning properties but is resistant to stuffiness and can be held comfortably and has improved hygiene characteristics.
Further, for example, a shoulder belt portion that is attached to a shoulder of a user holding the infant, a waist belt portion that is attached to a waist of a user holding the infant, and a side opposite to the user of the infant as the holding portion The elasticity made of the three-dimensional network structure can be arbitrarily selected depending on the part applied to the user and the part applied to the user side of the infant as the holding portion, so that the elasticity can be selected at an appropriate place.
In the holding part, since the three-dimensional network structure is disposed at a portion applied to the infant's body on the side opposite to the user, the three-dimensional network structure is provided at a portion that supports the infant's body over a wide area. The three-dimensional network structure relieves pressure, shaking, and shock, and does not force the infant's posture even when used for a long time. Since heat and heat are unlikely to accumulate in the three-dimensional network structure, it is possible to effectively prevent the heat and stuffiness of the infant, and the comfort for the infant becomes higher.
And since a part or all of the exterior fabric in which the cushioning material made of the three-dimensional network structure is placed is formed into mesh-like fibers that allow air to enter and exit, the continuous filaments constituting the three-dimensional network structure The supply of fresh air to the space between them and the discharge of air held in the space between the continuous striatum make it easier for infants and users to escape moisture and heat. The characteristics are further improved.

According to the baby carrier of the second aspect of the present invention, the buffer material disposed on the holding portion that holds the infant by being applied to the infant's body, the continuous linear body made of synthetic resin meanders irregularly. In addition, they are intertwined, and are fused in various places in the meandering state, and the space between the continuous filaments communicates to form a three-dimensional network structure having air permeability. According to this three-dimensional network structure, when an external force is applied, the curvature of the curved continuous filaments constituting the same changes, the space between the continuous filaments is deformed, and the external force is released, The striatum returns to its original curvature, and can express the cushioning properties (elasticity) that recover the space.
Moreover, the space between the continuous filaments constituting the three-dimensional network structure is communicated, and the air permeability is excellent.In particular, the space is also deformed by the movement of infants and users, and the flow of air is generated. Heat hardly stays and can prevent the occurrence of stuffiness.
Therefore, comfortable holding for the infant is obtained, and the burden on the infant is reduced even when used for a long time.

And, since moisture and heat hardly stay in the three-dimensional network structure in this way, it is difficult for bacteria and fungi to propagate, and further, the space between the continuous striatal bodies communicates with each other to make air permeability and moisture permeability. It is excellent in that it dries quickly, and the continuous filaments that make up the three-dimensional network structure are made of synthetic resin. They are irregularly meandered and intertwined, and are fused in a meandering state everywhere. Therefore, it has the strength to withstand repeated washing, and characteristics such as cushioning properties are unlikely to deteriorate even after repeated washing. Therefore, hygiene and cleanliness can be maintained.
In this way, a baby carrier that has cushioning properties but is resistant to stuffiness and can be held comfortably and has improved hygiene characteristics.
In addition, for example, a shoulder belt portion that is attached to a shoulder of a user holding the infant, a waist belt portion that is attached to a waist of a user holding the infant, and a side opposite to the user of the infant as the holding portion The elasticity made of the three-dimensional network structure can be arbitrarily selected depending on the part applied to the user and the part applied to the user side of the infant as the holding portion, so that the elasticity can be selected at an appropriate place.

In the holding part, since the three-dimensional network structure is disposed on the user's side where it is applied to the infant's body, when the three-dimensional network structure is covered with a breathable exterior fabric, Air passages are secured, and moisture and heat such as sweat from users and infants can be released. Moreover, even if the exterior fabric covering the three-dimensional network structure does not have air permeability, the space between the continuous filaments accommodates air, and the heat insulation effect by the three-dimensional network structure is obtained. Therefore, accumulation of heat and moisture due to close contact between the user and the infant can be prevented, and partial rise in body temperature and stuffiness can be prevented.
Since part or all of the exterior fabric in which the cushioning material made of the above-mentioned three-dimensional network structure is put is formed into a mesh-like fiber that allows air to enter and exit, between the continuous filaments constituting the three-dimensional network structure The supply of fresh air to the space and the discharge of air held in the space between the continuous striatum make it easier for moisture and heat from infants and users to escape, and hygienic characteristics Will improve further.
Therefore, it is possible to improve the holding comfort for the user and the infant.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Note that, in the embodiments, the same symbols and the same reference numerals are functional portions common to those embodiments, and thus detailed description thereof is omitted here.

  First, the three-dimensional network structure 100 as a cushioning material used for the baby carrier 1 of the present embodiment will be described with reference to FIGS. 1, 2, 7 and 8.

  As shown in FIG. 1, the three-dimensional network structure 100 as a buffer material is composed of a continuous linear body 101 made of a synthetic resin that is irregularly meandering and intertwined, and is adhered to everywhere in a meandering state. Is.

  Such a three-dimensional network structure 100 is disclosed in Japanese Patent Application Laid-Open Nos. 7-173753, 7-6801, 2001-328153, 2006-97223, and International Publication No. 20111035736. JP-A-2016-528, JP-A-2013-40437, JP-A-2007-130059, etc., the production method of which is described, and the product thereof is, for example, Toyobo Co., Ltd. As "Breath Air (registered trademark)", C-CORE from C-Engine Co., Ltd., "Air Weave (registered trademark)" from Airweve, "Hytrel (registered trademark)" from Toray DuPont It is possible to use such a commercial product that is sold and publicly known.

As a precaution, an example of a method for manufacturing the three-dimensional network structure 100 will be briefly described. As shown in FIG. 2, a nozzle provided with a plurality of perforations in which a molten thermoplastic resin is formed on the bottom surface of the extruder 200. From the (die), the continuous linear body 101 is extruded vertically downward to be supplied between the endless conveyors 211 and 212 arranged in parallel in the cooling water 210 at the lower position.
At this time, the interval between the endless conveyors 211 and 212 is formed so that the gap is smaller than the outer shape of the extruded continuous resin strip 101 so that the continuous strip 101 does not leak from the endless conveyors 211 and 212. I have to. Further, the water temperature and depth of the cooling water 210 in the water tank, the extrusion temperature of the continuous filament 101, and the like are set relative to the speed and position of the endless conveyors 211 and 212.

  Thereby, when the continuous filament 101 is extruded from a plurality of nozzles formed on the bottom surface of the extrusion molding machine 200, the extrusion speed is set faster than the conveyance speed between the endless conveyors 211 and 212. When extruded from a plurality of nozzles, the shape is linear, but as the temperature drops, the pushing force becomes a force in the left-right direction to form a three-dimensional network, and the three-dimensional network changes depending on the descending speed of the endless conveyors 211 and 212. At this time, the descending speed of the endless conveyors 211 and 212 is set to be slower than the extrusion descending speed of the continuous filament 101, and the continuous filament 101 is curved and partially joined. That is, the endless conveyors 211 and 212 in which the continuous filament 101 in a molten state extruded from the extrusion molding machine 200 is rotated slower than the descent speed of the continuous filament 101 due to the buoyancy and resistance of the cooling water 210. Is curved in a three-dimensional direction due to contact with the wire, and the continuous filaments 101 are partially welded, the welded portion is cooled by the cooling water 210, and the contact portions of the continuous filaments 101 are firmly bonded. At the same time, the continuous filament 101 is fixed. In this way, the continuous filament 101 is curled (curled) and intertwined randomly, and is partially welded to form a three-dimensional network structure 100 having a specific thickness.

  In the three-dimensional network structure 100 manufactured in this way, when a synthetic resin material to be melted is extruded as a continuous filament 101, a large number of them are curved and intertwined irregularly at a high temperature, It is welded, has a three-dimensional network structure, is formed with a predetermined thickness and width, and a space is formed between the continuous filaments 101, and the space communicates with the porosity of 70% to 98%. Have And the curved continuous linear body 101 has the elasticity which returns to the original curvature, when the curvature of curvature changes with external forces and an external force is cancelled | released. For this reason, in the three-dimensional network structure 100, the curvature of the curvature of the continuous filaments 101 is changed by an external force, and the space between the continuous filaments 101 is deformed, but when the external force is released, The curvature of the strip 101 returns to the original curvature, and the elasticity is such that the space is restored. That is, even when an external force is applied, the entire three-dimensional network structure 100 is deformed, and the stress is absorbed and dispersed by the rubber elasticity of the synthetic resin, and when the stress is released, the original form is restored. It is recovered and has moderate elasticity (cushioning) and resilience. In particular, since the continuous filaments 101 are fused to each other, when an external force is applied, substantially the entire three-dimensional network structure 100 disposed on the baby carrier 1 is integrally deformed, so that pressure dispersibility is obtained. In addition, it is difficult to cause partial settling and has excellent durability. It is excellent in elasticity (cushioning property), resilience and the like due to energy conversion in which the entire three-dimensional network structure 100 is deformed integrally.

Moreover, since it is formed with the continuous linear body 101 which consists of synthetic resins, and the porosity is also 70%-98%, it is lightweight. Since it consists only of synthetic resin, it is excellent in recyclability.
Furthermore, the space between the continuous filaments 101 is larger than that of the urethane material and the polyolefin-based foam, and the space is also in communication. The porosity is 70% to 98%, more preferably 85% to 98%. By having a porosity, it is excellent in air permeability and water permeability. For this reason, it is difficult for water to accumulate, it has a quick drying property, and in particular, since the material is a synthetic resin, the elastic restoring force is also good, and it is difficult to cause breakage, deformation, and settling due to folding and washing during storage. It is excellent in durability without being damaged or deformed by sterilization such as sodium chlorite. That is, since the continuous filaments 101 are fixed to each other, the continuous filaments 101 are not moved or the entire shape is not collapsed by compression or washing, and the bulkiness or elasticity is reduced. There is little setback.
And by being excellent in air permeability and quick-drying in this way, heat and moisture are easily dissipated and the rise in temperature and humidity is prevented, so that the growth of microorganisms can be suppressed. Even if washing such as washing with water is performed, there is no fear of causing growth of microorganisms until drying, and it is hygienic because it can be kept clean by washing.

Here, as the continuous filaments 101 constituting the three-dimensional network structure 100, a thermoplastic resin is used. For example, polyethylene, polyester, EVA (ethylene vinyl acetate copolymer), polyolefin such as polypropylene, polyester such as polyethylene terephthalate, etc. And polyamides such as nylon 66, polyvinyl chloride, polystyrene, EMMA (ethylene methyl methacrylate copolymer), and PET. A mixture of a copolymer or an elastomer copolymerized on the basis of these synthetic resins may be used.
In particular, EVA resin is rich in elasticity and can have high pressure dispersibility that disperses stress concentration. In addition, since polyethylene has a high melting point, it does not change its physical properties even when sterilized with hot water, steam sterilization, etc., and is suitable for more sanitary use.
Thus, when the continuous filament 101 which comprises the solid network structure 100 is a thermoplastic resin, it is excellent also in recyclability. Further, plastic deformation due to temperature rise when using the baby carrier 1 is small, and characteristics such as cushioning properties are stably maintained.

  The fineness of the continuous filaments 101 forming the three-dimensional network structure 100 is preferably in the range of 100 to 100,000 dtex, more preferably in the range of 300 to 50000 dtex, and still more preferably in the range of 500 to 30000 dtex. . Within this range, repulsive force, tensile stress (anticompressive force), etc. are good, and sag due to stress concentration hardly occurs, and high elasticity (cushioning property) is maintained over a long period of time. For this reason, the posture of the infant B held when used as a cushioning material is also stable, and a comfortable holding feeling can be obtained.

  Moreover, the continuous linear body 101 which comprises the solid network structure 100 may be a continuous linear body which consists of not only the continuous linear body which consists of a filament of a single fineness but a filament with which the fineness differs. In addition to a single type, a plurality of types of synthetic resins may be used.

Furthermore, the continuous filament 101 may be a hollow tube (tubular shape), a solid tube, or its cross-sectional shape is not particularly limited, and may be a circular cross-section. It may be an irregular cross-section different from a circular cross-section such as a polygonal cross-sectional shape such as a triangle or a quadrangle, a Y-shaped cross-sectional shape, or a star-shaped cross-sectional shape.
Since the hollow tube (tube shape) is lighter, the solid line structure 100 having the same weight as that of the solid tube has a high density of the continuous filaments 101 and is hard. It is also possible to select the shape of the continuous striatal body 101 according to the part applied to the infant or the user's body. For example, in a region applied to an infant's buttocks, the use of the low-density three-dimensional network structure 100 made of solid continuous filaments 101 allows the infant's buttocks to be softly received with a soft touch, and the lowering of the buttocks is more enhanced. Can be stabilized. In addition, the use of the low-density three-dimensional network structure 100 at the site applied to the infant's ventral side and the user's side improves the adhesion between the infant and the user with a soft feel and improves the comfort of holding. . On the other hand, in the part applied to the infant's head and back, the infant has sufficient strength to support the infant's weight by using the high-density and hard three-dimensional network structure 100 formed of the hollow continuous filaments 101. The posture can be stabilized and the weight can be highly dispersed. Further, the waist belt portion and the shoulder belt attached to the user's waist and shoulders can be received and highly dispersed by the strength that firmly supports the weight of the infant by using the high-density three-dimensional network structure 100.

  In the present embodiment, when the three-dimensional network structure 100 is disposed on the baby carrier 1, the front and back end surfaces that have surfaces with the largest areas are located on the front side and the back side that are opposed to each other in the thickness direction. Most of the contact portions between the continuous filaments 101 are welded and flattened without exposing the continuous lengthwise ends of the stripes 101. That is, they are connected two-dimensionally. Thereby, there is no fear that the surface that hits an infant or a user gives a feeling of bumpiness or incongruity, and the exposed end portion in the length direction of the continuous filament 101 is caught by an exterior fabric 150 described later that covers the three-dimensional network structure 100. There is no damage. In addition, due to the two-dimensional connection, even when a local external force is applied to the surface, settling due to stress concentration does not easily occur and the external force is received by the surface. High pressure dispersibility to absorb and disperse water. Therefore, the burden on the body can be eased, the holding posture can be stabilized, the holding comfort and the contact with the body can be improved.

Note that such two-dimensional welding in which the end portions in the length direction of the continuous filament 101 are not exposed on the front and back end surfaces is formed by contact with the endless conveyors 211 and 212 facing each other. Of course, most of the contact portions between the continuous filaments 101 are welded and aligned in a flat shape without the continuous lengthwise ends of the continuous filaments 101 appearing on three or more outer peripheral surfaces. It may be.
In the case of carrying out the present invention, if the pair of opposed front and back end faces are such that the continuous lengthwise ends of the continuous linear body 101 do not appear, the surface layer is corrugated, continuous irregularities , Convex or concave shape, saw shape, corners may be formed in a curved surface (R) or chamfered shape.

Further, the three-dimensional network structure 100 may have a uniform overall density or may be dense.
In particular, if the front and back sides in the thickness direction are higher than the density of the inner layer, it is difficult to get loose, and a comfortable holding feeling with high pressure dispersibility can be obtained. On the other hand, for example, by increasing the density of the continuous filaments 101 on the other surface side rather than the one surface side that is applied to the infant's body, that is, the closer to the infant, the lower the density and elasticity. Softer, the farther away from the infant, the higher the density and the elasticity on the opposite side of the infant. can get.
Moreover, the characteristic and density may be changed in the thickness direction (in the form of a layer) by a combination of synthetic resins (continuous filaments 101) having different compositions and characteristics.

The density of the three-dimensional network structure 100 is adjusted by adjusting the distribution density of the continuous filaments 101 by adjusting a plurality of drilling positions and intervals of nozzles (dies) that extrude the continuous filaments 101 shown in FIG. Or by adjusting the thickness of the continuous filament 101 by adjusting the size of the plurality of perforations in the nozzle, or by adjusting the supply speed of the synthetic resin from the nozzle. . It can also be adjusted by changing the interval between the endless conveyors 211 and 212 and the rotational speed of the endless conveyors 211 and 212. Increasing the rotational speed of the endless conveyors 211 and 212 can reduce the rotational speed. It can be formed with high density by slowing down.
That is, in the three-dimensional network structure 100, even if it is the same thickness, the density is changed depending on the extrusion speed of the continuous filament 101 and the transport speed of the endless conveyors 211 and 212, thereby providing cushioning from soft to hard. it can. Further, it can be changed by the extrusion thickness of the continuous filament 101.

  Thereby, for example, as shown in FIG. 7, the density between the continuous filaments 101 is increased compared to the three-dimensional network structure 100 shown in FIG. 1, and the dense three-dimensional network structure 100 is used. Alternatively, as shown in FIG. 8, a low-density three-dimensional network structure 100 in which the density between the continuous filaments 101 is reduced as compared with the three-dimensional network structure 100 shown in FIG. 1 may be used.

  Incidentally, as shown in FIG. 2, the continuous line body 101 is placed on the upper part of the water tank containing the cooling water 210 in the lower part of the extrusion molding machine 200 before and after the continuous line body 101 reaches the cooling water 210. By installing a four-sided funnel-shaped guide plate (chute) 220 that is narrowed in order to receive and guide it to the endless conveyors 211 and 212, the continuous linear body 101 extruded from the hole of the nozzle (die). A part of the guide strip 220 slides on the slope of the guide plate 220 and is guided to the endless conveyors 211 and 212. At that time, the continuous filaments 101 are entangled and welded on the surface of the guide 220 plate, toward the inner layer. The surface layer having a high density can be formed by narrowing down. At the same time, the end surface of the surface layer is formed flat by sliding on the flat guide plate 220.

In the baby carrier 1 of the present embodiment, the three-dimensional network structure 100 used as a cushioning material is, for example, 25% compressive hardness (based on JIS K 6400-2, the three-dimensional network structure 100 has a diameter of 200 mm. The stress when compressed to 75% with a circular compression plate and then compressed again by 25%) is in the range of 10 N / φ200 or more and 200 N / φ200 or less, more preferably 15 N / φ200 or more and 180 N / φ200 or less. Is done. The average apparent density is in the range of 0.005 to 0.90 g / cm, more preferably 0.02 or more and 0.20 g / cm ³ or less, still more preferably 0.05 or more and 0.15 g / cm ³ or less. It is assumed to be inside. If it is within the above range, cushioning, shock absorption, and pressure dispersibility are good with moderate hardness, good contact with the body of the infant B or the user M, and the baby carrier 1 is worn for a long time. There is little stiffness and less burden. Further, the thickness of the three-dimensional network structure 100 can be selected depending on the arrangement location and the like, and is not particularly limited. However, if the thickness is within a range of 3 mm to 30 mm, more preferably 3 mm to 20 mm, a buffer function is easily exhibited. It has flexibility and flexibility so that it can be bent corresponding to the body shape of the infant B or the user M.

  Such a three-dimensional network structure 100 can be formed not only by extrusion molding but also by mold fitting, and the continuous filaments 101 are not limited to fusion bonding but are bonded by an adhesive. It may be a thing. In any case, the continuous wire body 101 made of synthetic resin is irregularly meandering and intertwined, and the three-dimensional network structure 100 formed by bonding in a meandering state is easy to manufacture and process. In addition, there are almost no pollution problems of chemicals used during production, dioxins are not generated during incineration, and recyclability is also high.

  As described above, the three-dimensional network structure 100 as a cushioning material used in the baby carrier 1 according to the present embodiment has the continuous linear body 101 made of synthetic resin irregularly meandering and intertwined, It melts everywhere in a meandering state, has a specific thickness, and communicates with the space between the continuous filaments 101 and has air permeability. Note that the directionality of ventilation and water permeability is not specified.

Next, an example of the baby carrier 1 using the three-dimensional network structure 1 having such a configuration as a cushioning material will be described mainly with reference to FIGS. 1 and 3 to 6.
The baby carrier 1 according to the present embodiment is a holding unit for holding the infant M applied to the body of the infant M by holding or riding the infant M, on the side opposite to the user M side such as a parent holding or holding the infant B. A main body 10 applied to the body of the infant B and supporting the weight of the infant B; an auxiliary holding section 20 connected to the lower part of the main body 10 and applied to the body of the infant B on the opposite side of the main body 10; It has a positioning seat portion 30 disposed between the main body portion 10 and the auxiliary holding portion 20. Furthermore, it is connected to the auxiliary holding part 20 and is connected to the pair of left and right shoulder belt parts 40 that are hung on the shoulder of the user M, and the lower end part of the main body part 10 and the auxiliary holding part 20 to be connected to the main body part 10 and the auxiliary holding part. The waist belt portion 50 is disposed in a direction perpendicular to the length direction of 20 and is worn around the waist of the user M.

The main body 10 applied to the body of the infant B on the opposite side of the user M holding the infant B is a face-to-face hug in which the face of the infant B and the user M face each other or the face of the infant B and the user M Like the forward facing piggyback facing in the same direction, when the infant B is held so that the abdomen of the body of the infant B faces the user M such as a parent holding the infant B, it is applied to the back side of the body of the infant B It is.
The main body portion 10 of the present embodiment is a substantially semi-elliptical head support portion 11 that is mainly applied to the head of the baby B and receives the head mainly when the baby B is held with a face-to-face hug or a forward-facing piggyback. And a back support part 12 that is applied from the head side of the infant B to the back and waist and receives mainly the back part, and a support part 13 that is applied from the back side of the infant B to the buttocks part and mainly receives the hip part. Are integrally formed.

In the present embodiment, a three-dimensional network structure 100 as a cushioning material is disposed on the main body portion 10 including the head support portion 11, the back support portion 12, and the heel support portion 13.
Specifically, as shown in FIG. 1B, the three-dimensional network structure 100 as a cushioning material is covered with an exterior fabric 150 including a front fabric 110 and a back fabric 120 and is disposed in the main body 10. The That is, the three-dimensional network structure 100 as a cushioning material is put in an exterior fabric 150 made up of a front fabric 110 and a back fabric 120 closed in a bag shape, and the main body 10 is configured.

  Thus, in the main body 10, the exterior fabric 150 made of two cloths, the front fabric 110 and the back fabric 120, wraps around the three-dimensional network structure 100 as shown in FIG. The front fabric 110 and the back fabric 120 may be formed by folding a single fabric, or may be formed by three or four. In particular, in the present embodiment, the front fabric 110 and the back fabric 120 may be folded and overlapped and sewn with two sewing threads, or a pie pin may be sewn with one of them. Alternatively, a bag shape may be formed by the front fabric 110 and the back fabric 120, and the three-dimensional network structure 100 may be inserted therein.

In the baby carrier 1 of the present embodiment, the outer fabric 150 of the front fabric 110 and the back fabric 120 constituting the main body 10 is at least the entire inner surface (infant B side) applied to the body of the infant B, or one The cloth which has air permeability is used in the position corresponding to the surface of the part, for example, the body of the infant B.
Examples of the breathable fabric include a net fabric having a mesh / mesh structure with a predetermined opening, a coarse fabric with a slightly rough texture, and an air layer having a specific thickness between the front and back net fabrics. A three-dimensional knitted fabric (double raschel) having a specific thickness formed by weaving the connecting yarn to be formed is used. By forming the exterior fabric 150 into a mesh-like fiber by using such a breathable fabric, the breathability is ensured, and the moisture absorption from the surface in contact with the infant B is increased, and moisture and heat are dissipated. can do. Hygroscopicity is also improved by using a material such as a cotton material with high water absorption.

  In particular, according to the three-dimensional knitted fabric (double raschel), against the generation of moisture and heat such as sweat of infant B and user M by the air layer formed by the connecting yarn woven between the mesh fabrics of the front and back, It has a volume that can accommodate the moisture and heat, and further, the movement of the user M and the movement of the infant B become the volume change of the air layer, and the air in the air layer is discharged and supplied. The sweat sweated from the body of M or the infant B can be quickly absorbed, and the heat of the body of the user M or the infant B can be released. Of course, because the mesh fabric and air layer on the front and back sides are excellent in air permeability and water permeability, moisture can be dried quickly. Furthermore, the air layer formed by the connecting yarn has some elasticity (cushioning), etc., and even if the infant B moves, the following change in the air layer does not cause a sense of incongruity, and the infant B's body shape fits in Good.

  Such a three-dimensional knitted fabric (double raschel) is manufactured by a woven fabric manufacturing machine such as a double raschel machine or tricot machine. The product is “Fusion (trade name)” from Asahi Kasei Co., Ltd. Since it is sold as “Aqueen (trade name)”, detailed explanation is omitted here.

When carrying out the present invention, the above-described fabric having air permeability may be used on the inner surface side of the main body 10, that is, the entire surface on the infant B side, or may be used partially. . In particular, it may be used only for the head support part 11 and the back support part 12 applied to the head and the back part where the infant B is likely to perspire. Also good. Only one of the head support part 11, the back support part 12, and the heel support part 13 may be used, only the head support part 11 and the back support part 12, only the head support part 11 and the heel support part 13, Only the abutment part 12 and the abutment part 13 may be used, or the head abutment part 11, the back abutment part 12 and the abutment part 13 may all be used. Of course, each part of the head support part 11, the back support part 12, and the padding part 13 may be sufficient.
Moreover, you may use not only the inner surface side of the main-body part 10 but the exterior cloth | dough 150 of the outer surface side of the main-body part 10, and you may use the cloth which has air permeability, the inner surface side (infant B side) and outer surface ( A structure that allows air to flow in the thickness direction on both the front and back surfaces of the baby B) is desirable. If the front and back surfaces of the main body 10 are formed of a predetermined mesh-like fiber, air passages in the thickness direction of the front and back surfaces are secured, so that the amount of ventilation increases and moisture and heat can be released more effectively. it can. Moreover, you may form in the two-layer structure which can coat | cover the non-breathable cloth with respect to the cloth which has air permeability in a specific part. In any case, in the exterior fabric 150, all or a part of the exterior fabric 150 forms an opening through which air is discharged and supplied by using a fabric having air permeability, so that a three-dimensional mesh shape inserted between the front fabric 110 and the back fabric 120 is formed. Any structure may be used as long as the air permeability of the structure 100 is utilized to maintain the air permeability.

  In addition, the fluid resistance which determines the inflow / outflow of air can be arbitrarily set by the size and number of mesh holes, that is, by selecting the mesh density. Furthermore, the mesh density may be changed according to the part of the infant B to be matched. For example, in the face of baby B and easy-to-touch parts, the fine mesh of the eyes improves the touch, and in the head support part 11 and the back support part 12 corresponding to the head and back part where the infant B tends to sweat, A rough mesh can ensure high air permeability. Further, the shape of the mesh may be determined in terms of design. The mesh structure is not necessarily required, and air circulation may be ensured by a plurality of openings.

  The exterior fabric 150 including the front fabric 110 and the back fabric 120 of the main body 10 can be formed of any fabric except for a fabric having air permeability. Further, the kind of the fabric may be changed according to the part of the infant B to be matched. For example, a soft fabric, a soft fabric with soft feeling, or a non-irritating fabric is used near the head of the infant B. A fabric with high hygroscopicity is used near the head and back of the infant B. The material of the fabric may be selected in terms of design and mechanical strength.

  And in the baby carrier 1 of this Embodiment, it consists of a synthetic resin as a buffering material inside the bag-shaped exterior fabric 150 which consists of the front fabric 110 and the back fabric 120 with which air permeability is ensured in this way. A continuous wire body 101 is irregularly meandering and entangled, and a three-dimensional network structure 100 having a specific thickness formed by welding in a meandering state is disposed.

The three-dimensional network structure 100 may be disposed throughout the main body 10 in accordance with the purpose of the baby carrier 1 (the age of the object to be retained, the retention form, etc.), the characteristics and characteristics of the commercial value, and the like. However, only a specific part may be provided. In other words, only the head support 11, the back support 12, or the heel support 13 may be disposed, or only the head support 11 and the back proof 12, the head support 11 and the heel support 13. Only the back support part 12 and the abutment part 13 may be provided, or the head support part 11, the back support part 12 and the abutment part 13 may be provided as a whole. Preferably, it is filled with an area equivalent to each part in order to prevent displacement, but may be a part of each of the head support part 11, the back support part 12, and the heel support part 13, in which case the part For example, a misalignment prevention means such as sewing on the exterior fabric 150 or forming a housing portion in the exterior fabric 150 is provided.
In addition, as described above, the three-dimensional network structure 100 can be adjusted in characteristics such as hardness, softness, elasticity, etc. according to its density, size, thickness, material of raw material, shape of the continuous filament 101, and the like. Therefore, for example, it is possible to select the three-dimensional network structure 100 having different characteristics (density, thickness, etc.) depending on the arrangement position and site, such as using a soft material for the back support portion 12 and a soft material for the support portion 13. It is.
The three-dimensional network structure 100 disposed in the main body portion 10 has a thickness of 3 mm or more and 30 mm or less, more preferably 3 mm or more and 20 mm or less. It is easily expressed and has flexibility and softness to the extent that it can be bent corresponding to the body shape of the infant B or the user M, and further, it is less bulky when being carried.

For example, by disposing the three-dimensional network structure 100 on the head support 11, the head of the infant B is supported to prevent glare, to prevent backward tilting, and to shock the head. Can be tempered. In addition, the surrounding sound can be attenuated to form a comfortable sleep environment.
In particular, the hardness at the time of 25% compression of the three-dimensional network structure 100 arranged in the head support 11 (the three-dimensional network structure 100 was compressed to 75% with a 200 mm-diameter circular compression plate and then compressed again by 25%. Stress) is preferably in the range of 10 N / φ200 or more and 180 N / φ200 or less, more preferably in the range of 10 N / φ200 or more and 130 N / φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 15 kg / φ150, more preferably 4 kg / φ150 to 10 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 10 kg / φ150 to 30 kg / φ150.
If it is within the above range, the head holder 11 that is applied to the head of the infant B firmly supports the head of the infant B without having to put a hard core material in the exterior fabric 150 separately. Since the head can be prevented from tilting and warping backward, the head of the infant B is firmly supported even when the infant B is held or when the infant B is asleep, and the head is prevented from being blurred. It is possible. Furthermore, the vibration and shock absorption by the user M walking and the like are high, and the burden on the head and neck of the infant B can be reduced.

Further, by arranging the three-dimensional network structure 100 on the backrest 12, the comfort for the infant B is improved, and the posture of the infant B and the stability of the holding are also improved.
In particular, the 25% compression hardness of the three-dimensional network structure 100 disposed in the backrest 12 is preferably in the range of 10 N / φ200 or more and 180 N / φ200 or less, more preferably 10 N / φ200 or more. , 150 N / φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 20 kg / φ150, more preferably 3 kg / φ150 to 15 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 15 kg / φ150 to 30 kg / φ150.
If it is within the above range, the back portion 12 applied to the back from the waist of the infant B without a hard core is supported firmly from the waist of the infant B to prevent falling. Thus, a stable posture of the infant B can be maintained, and even when the user M cannot reach the eyes, the infant B can be prevented from warping.

Further, by disposing the three-dimensional network structure 100 in the abutment portion 13, the buttocks of the infant B are likely to fall, the center of gravity of the infant B is stabilized, and the holding stability is improved. Moreover, the pressure applied to the buttocks of the infant B is easily dispersed, the sitting comfort is improved, and the burden on the infant B is reduced.
In particular, it is preferable that the hardness at 25% compression of the three-dimensional network structure 100 disposed in the holding portion 13 is within a range of 10 N / φ200 or more and 150 N / φ200 or less in the center portion 13A described later. Is in the range of 10 N / φ200 or more and 130 N / φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 20 kg / φ150, more preferably 3 kg / φ150 to 10 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 5 kg / φ150 to 25 kg / φ150.
If it is within the above range, the lower part of the buttocks of the infant B can be easily lowered, the center of gravity of the buttocks can be stabilized to prevent the position shift, thereby obtaining a stable sinking of the infant B and improving the holding stability. It is possible to hold in a comfortable posture with less burden on M and infant B. Moreover, even if it touches the leg of the infant B, it follows it, and the movement of the leg of the infant B is difficult to be restricted. In particular, even when holding an infant B of a young age before the neck is set, the knee of the infant B is easily bent down, so that the knee is bent at a position higher than the position of the buttocks of the infant B, and an M-shaped spread leg is formed. In a natural open leg posture, the center of gravity of the infant B is not on the leg side but on the buttocks, and the body shape of the infant B can be held with a low burden.

  Here, in the abutment portion 13 of the present embodiment, a center portion 13A that receives the center side of the buttocks of the infant B and a pair of left and right end portions 13B that are located on the left and right sides of the center portion 13A and that are near the thighs of the infant B It consists of and.

  In the baby carrier 1 according to the present embodiment, the center portion 13A and the left and right end portions 13B of the holding portion 13 are formed by draping, and the center portion 13A and the end portion 13B are located inside (center side). Is joined by a sewing line 13a that is curved in an arc shape toward the upper side, and further, the lower end portion of the abutment portion 13 is joined to the upper end portion of the main body belt portion 51 with respect to the main body belt portion 51 of the waist belt portion 50 described later. A three-dimensional accommodation space is formed by integrally connecting a straight sewing line and a sewing line (not shown) curved in an arc shape below the sewing line. This makes it difficult for the movement of the leg of the infant B to be restrained when held at a high position, which will be described later, and the position of the center of gravity of the buttocks of the infant B is easily stabilized.

  At this time, the connection between the central portion 13A and the end portion 13B in the holding portion 13 is performed by not making the three-dimensional network structure 100 inserted between the front fabric 110 and the back fabric 120 continuous, or by making the three-dimensional network structure 100 continuous. Even if the front fabric 110 and the back fabric 120 are stitched, or the three-dimensional network structure 100 itself is formed to be foldable, the central portion 13A and the end portion 13B are distinguished from each other, and the central portion An end portion 13B is formed so as to be bent toward the infant B side with respect to the surface of 13A.

  In particular, since the outer shape of the center portion 13A joined to the end portion 13B by the sewing line 13a is a shape curved toward the center side, that is, a shape narrower on the center side than the upper and lower end portions, When the three-dimensional network structure 100 is provided, the buttocks of the infant B are likely to fall, and the misalignment of the buttocks hardly occurs. Therefore, the infant B can be held in a comfortable posture with less burden, and the holding stability can be increased.

  In the case of carrying out the present invention, the thickness of the three-dimensional network structure 100 put in the outer fabric 150 of the front fabric 110 and the back fabric 120 is changed. Cushioning and flexibility of the three-dimensional network structure 100 put into the exterior fabric 150 of the front fabric 110 and the back fabric 120 by forming a recess so that the heel portion can freely fall by adding a change Also by adopting a structure that changes the sex, the drop of the buttocks of the infant B can be stabilized and the holding stability can be improved.

  Furthermore, since the outer edge of the end portion 13B of the abutment portion 13 comes into contact with the thigh of the infant B, it is easy to apply a large load to the thigh of the infant B. In 13B, the arrangement of the three-dimensional network structure 100 having a cushioning property (elasticity) higher than that of the central portion A can reduce the pressure of the infant B on the thighs. For example, the three-dimensional network structure 100 disposed in the end portion 13B preferably has a 25% compression hardness within a range of 10 N / φ200 or more and 180 N / φ200 or less, more preferably 10 N / φ200 or more. , 130 N / φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 15 kg / φ150, more preferably 4 kg / φ150 to 10 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 10 kg / φ150 to 30 kg / φ150.

Moreover, in the baby carrier 1 of the present embodiment, the horizontal width in the horizontal direction is narrow at the boundary between the backrest portion 12 and the abutment portion 13 and the design is such that the abutment portion 13 widens downward from there. In particular, the butting part 13 makes it easy for the baby B to drop the buttocks, but the three-dimensional network structure 100 disposed in the back rest part 12 and the three-dimensional network structure 100 disposed in the butting part 13 are cushions. By changing characteristics such as property and hardness, for example, the hardness of the three-dimensional network structure 100 disposed in the abutment portion 13 is made softer than that of the three-dimensional network structure 100 disposed in the back support portion 12. However, by reducing the cushioning property, the posture of the infant B can be firmly supported by the back support unit 12, but the buttocks of the infant B can be easily lowered by the support unit 13.
In particular, since the three-dimensional network structure 100 has high air permeability, even if the thickness of the three-dimensional network structure 100 is increased to increase cushioning properties and hardness, it is possible to prevent stuffiness.

  As described above, the hardness, repulsive force, and cushioning properties of the three-dimensional network structure 100 are determined by its density, size, thickness, material material, shape of the continuous filament 101, and the like. Therefore, the density of the three-dimensional network structure 100, the material of the raw material, and the shape of the continuous filaments 101 may be unified, and a desired hardness may be obtained by changing only the thickness, or the three-dimensional network structure 100. May be obtained to obtain a desired hardness, repulsive force, cushioning characteristics, etc. by changing the material to a uniform thickness, and changing the material of the constituent material, the shape of the continuous filament 101, the density, and the like. .

  As described above, according to the baby carrier 1 of the present embodiment, a bag-shaped exterior fabric 150 including the front fabric 110 and the back fabric 120 that are partially or entirely formed of a fabric having air permeability to ensure air permeability. In particular, a continuous filament 101 made of a synthetic resin is irregularly meandering and entangled as a buffer material in a specific part or in the whole, and it is fused in a meandering state everywhere. A three-dimensional network structure 100 having a specific thickness formed by communicating a space between the bodies 101 is inserted to form the main body 10.

  Therefore, a buffering action and cushioning properties (elasticity) can be obtained at the portion where the three-dimensional network structure 100 is disposed. In this three-dimensional network structure 100, the space between the continuous filaments 101 constituting the three-dimensional network structure 100 is continuous. Therefore, it has air permeability, preferably with a porosity of 70% to 98%. For this reason, even if the three-dimensional network structure 100 is provided as a cushioning material, air passages are formed by the gaps between the continuous filaments 101, and the three-dimensional structure is caused by the movement of the infant B or the user M. Since the flow of air is generated by the volume change of the space of the net-like structure 100, heat and moisture are less likely to stay, and it is difficult for the infant B to be hot or stuffy.

  Since the three-dimensional network structure 100 is excellent in air permeability and hardly retains moisture and heat as described above, the continuous filament 101 is formed by irregularly meandering of the continuous filament 101 made of synthetic resin. Because most of them are loop-shaped and it is difficult for synthetic resin waste to come out, bacteria, molds, etc. are difficult to propagate compared to urethane and polyolefin foams used as conventional cushioning materials. Odor due to permeation of sweat from M and propagation of bacteria, mold, etc. hardly occurs. Furthermore, the continuous space between the continuous filaments 101 is excellent in air permeability and moisture permeability, so that it has a quick drying property, and even if it is washed, the moisture will dry quickly, and there is a risk that bacteria will grow before drying. Without washing, hygiene and cleanliness can be maintained. It can dry quickly and prevent the growth of bacteria, mold, etc., even when the baby B is drooling or adhering to water such as spitting back. Therefore, hygiene characteristics are improved. Further, the continuous filaments 101 constituting the three-dimensional network structure 100 are made of synthetic resin, and they are irregularly meandering and entangled, and are fused in a meandering state everywhere. It has the strength to withstand, and even if it is repeatedly washed, characteristics such as cushioning and cushioning properties are unlikely to deteriorate. That is, since the continuous filaments 101 are fixed to each other, the continuous filaments 101 are not moved or the entire shape is not collapsed by compression or washing, and the bulkiness or elasticity is reduced. There is little setback.

  In particular, in the present embodiment, the three-dimensional network structure 100 is covered with an exterior fabric 150 that is partially or entirely made of a fabric having air permeability, and an air flow path is formed by the air permeability of the exterior fabric 150, The heat and moisture of the infant B's body can be released. Furthermore, since fresh air is supplied to the three-dimensional network structure 100 put in the outer fabric 150 due to the air permeability of the outer fabric 150, the exhaust of moisture and high-temperature air entering the three-dimensional network structure 100 is promoted. Is done. That is, the three-dimensional network structure 100 has a volume that can store moisture and heat against the generation of moisture and heat such as sweat of the infant B due to its high porosity, but the exterior fabric 150 that covers the moisture and heat is breathable. By having fresh air, fresh air is taken in and it becomes easy to escape moisture and heat. In particular, the movement of the user M and the movement of the infant B result in a change in the volume of the space (space) between the continuous filaments 101 constituting the three-dimensional network structure 100, thereby promoting the supply and discharge of air in the space. Is done. Therefore, sweat sweated from the body of the infant B through the exterior fabric 150 can be quickly absorbed, and the heat of the user M and the body of the infant B can be released. Therefore, it is difficult for moisture and heat to accumulate in the three-dimensional network structure 100, and the heat and stuffiness of the infant B can be reduced. In addition, the body temperature of the infant B is partially and abnormally prevented even when held for a long time, and there is little tingling and stickiness, and it is a countermeasure against sweating, heat and stuffiness, and sweating.

  More preferably, both the front fabric 110 and the back fabric 120 of the exterior fabric 150, that is, the both surfaces (front and back) of the main body 10 with the surface applied to the body of the infant B and the side surface opposite thereto are breathable. When the fabric is used, the air permeability in the thickness direction of the main body 10 is increased by the air permeability of the three-dimensional network structure 100 and the fabric of the front and back surfaces, so that moisture and heat can be released more effectively. It can be refreshed and refreshed. In addition, if both the front and back surfaces (opposite surfaces) of the main body 10 are mesh-like, the fluid resistance that determines the entry and exit of air according to the body shape and operation of the user M and the infant B can be arbitrarily set.

In this way, the continuous linear body 101 made of a synthetic resin is irregularly meandering and intertwined, and the three-dimensional network structure 100 having a specific thickness formed by welding in a meandering state everywhere. For example, although the void ratio is high, the continuous filaments 101 constituting the same are made of synthetic resin, and are subjected to external force over the entire surface because they are entangled and fused in a three-dimensional manner. Compared to urethane and polyolefin-based foams, the weight is reduced as equivalent cushioning properties. Therefore, the weight and carrying burden for the user M who wears can be reduced.
In addition, the three-dimensional network structure 100 has faster recovery characteristics than conventional urethane and polyolefin-based foams that have been used as cushioning materials for the baby carrier 1, and has a fitting property and embrace that follows the body movement of the infant B. Holding property can be obtained, and holding comfort and holding stability can be improved. Therefore, even if the thickness is reduced, an appropriate cushioning property can be obtained and the bulkiness can be reduced.

  In addition, according to the three-dimensional network structure 100 in which the continuous filaments 101 are entangled three-dimensionally and have a continuous space, the concentration of weight stress can be reduced by uniformly supporting the area of the infant B. That is, the pressure receiving area is widened by the provision of the three-dimensional network structure 100, and the pressure applied to the infant B is easily dispersed. Therefore, the burden concerning the body shape of the infant B can be reduced. In particular, in the abutment portion 13 where the center of gravity of the infant B comes, the three-dimensional network structure 100 is disposed so that the pressure applied to the buttocks of the infant B is dispersed even when the infant B is held for a long time. It becomes comfortable and the burden on the buttocks of the infant B is reduced.

  In the present embodiment, even if the three-dimensional network structure 100 is disposed in the head support part 11 and the back support part 12, the front fabric 110 and the back fabric 120 at the boundary between the head support part 11 and the back support part 12. The three-dimensional network structure 100 placed between the outer fabrics 150 is not continuous, or even if the three-dimensional network structure 100 is continuous, the three-dimensional network structure 100 itself can be bent, so 11 and the backrest portion 12 are distinguished, and the headrest portion 11 can be bent with respect to the surface of the backrest portion 12. Thereby, although the back part 12 supports the back part of the infant B from the waist stably, the head part 11 is easily inclined with respect to the surface of the back part 12 according to the weight of the head of the infant B. (It is easy to bend) and the head and neck of the infant B can be protected so as not to overload the head and neck of the infant B. Further, the field of view of the infant B can be expanded by using the head support part 11 by bending the head support part 11 on the side opposite to the infant B side with respect to the surface of the back support part 12 according to the growth of the infant B.

  Furthermore, in the baby carrier 1 of the present embodiment, on the side where the infant B of the main body 10 is arranged, the surfaces of the head support 11 and the back support 12 at the boundary between the head support 11 and the back support 12. A connection portion 14 having a substantially triangular shape is provided so as to protrude from the right side, and this connection portion 14 supports the tilt of the head of the infant B in the left-right direction, prevents glare and prevents a burden on the head and neck of the infant B. Can be reduced. In particular, by forming the connecting portion 14 with a material having cushioning properties, the impact and the head and neck of the infant B can be protected. And it is also possible to arrange | position the three-dimensional network-like structure 100 as a buffer material in this connection part 14. FIG. In other words, the three-dimensional network structure 100 may be inserted between the front fabric 110 and the back fabric 120 of the exterior fabric 150 constituting the connection portion 14.

The head support 11 is provided with a pocket-shaped storage portion having a predetermined storage volume (not shown), and is a surface on the opposite side of the main body 10 shown in FIG. A slide fastener 15 (a hook, a button, an adhesive cloth, etc.) for opening and closing a storage portion (not shown) on the design surface side when the user M is wearing the baby carrier 1 may be used. ), And can accommodate a head hood (not shown) having a predetermined area covering the head of the infant M, items such as a cooling agent and a towel. For example, the head hood (not shown) has one end fixed to the storage portion by sewing or the like, and the other end connected to the shoulder belt portion 40 (for example, a buckle, hook, eggplant, carabiner, D lock, quick catch, The head of the infant B is covered and supported from the back of the head, and the head of the infant B falls backwards even when the infant B is sleeping. It functions as a cover that hides breastfeeding when the baby B is fed while being held while the baby carrier 1 is worn, or the like is prevented.
In addition, it is desirable for this head hood to have air permeability, and by using the three-dimensional network structure 100 as a cushioning material, air permeability can be ensured.

  And in the baby carrier 1 of this Embodiment, the main body part 10 in which the head support part 11, the back support part 12, and the support part 13 are integrally formed in this way is the lower end part on the side of the support part 13. The waist belt portion 50 is sewn with a linear sewing line and an arc-shaped sewing line (not shown). The main body portion 10 and the waist belt portion 50 are disposed in a substantially inverted T shape as a whole, and are sewn integrally with the waist belt portion 50 by sewing the lower end of the main body portion 10 and the vicinity thereof, thereby providing a waist belt. The main body 10 can be bent in a direction perpendicular to the surface direction of the portion 50.

  The waist belt portion 50 is disposed in a direction substantially orthogonal to the length direction (vertical direction) of the main body portion 10 and the auxiliary holding portion 20 below the main body portion 10 and the auxiliary holding portion 20 described later. As a form in which the weight (the weight of the infant B) is distributed so that it can withstand the strength because it receives a lot of body weight, and it does not overload the body shape of the user M even if it is attached to the waist of the user M And a main body belt portion 51 that is integrated with the main body portion 10 and an auxiliary holding portion 20 that will be described later, and a fabric belt that has a wide belt and has a buckle with an adjuster disposed at both ends in the longitudinal direction of the main body belt portion 51. It comprises a pair of left and right length adjusters 52. The waist belt portion 50 can be fixed around the waist of the user M by the coupling engagement of the coupling insert 53 of the buckle with adjuster provided in the length adjusting unit 52 and the coupling receiver 54, and the coupling insertion By making the tool 53 and the connection receiver 54 connectable, the user 53 can freely attach and detach the waist of the user M.

  As described above, in the waist belt portion 50, the pair of left and right length adjusting portions 52 provided at both ends of the main body belt portion 51 are predetermined so that the belt length necessary for attaching the user M around the waist is determined. The connection insertion tool 53 and the connection receiver 54, each of which is made of a pair of male and female buckles with an adjuster, have an adjuster function, so that the length of the waist of the user M can be adjusted. . The adjuster may be an independent adjuster as long as the belt length can be adjusted, or may be an integrated adjuster.

  The main body belt portion 51 having a wide vertical width is formed of, for example, a material having a predetermined flexibility, flexibility, elasticity, hardness, and the like in which a cushioning material is inserted between the outer fabric 150 of the front fabric 110 and the back fabric 120. It improves the familiarity of the user M around the waist, enhances the fit so as not to bite in, makes it easier to distribute the load on the waist of the user M, and reduces the burden on the user M ing. Preferably, in the main body belt portion 51 as well, it is possible to prevent stuffiness and reduce discomfort by using the breathable fabric as described above for all or part of the exterior fabric 150 constituting the body belt portion 51. . In addition, the hygroscopicity can be improved by forming at least the inner surface that touches the waist of the user M with a water absorbent cotton fabric or the like.

  When practicing the present invention, the outer fabric 150 of the front fabric 110 and the back fabric 120 is composed of a core material made of hard urethane or polyolefin foam as a cushioning material and a soft urethane or polyolefin foam. The main body belt portion 51 can be formed using a cushion material, or the main body belt portion 51 can be formed by inserting a three-dimensional network structure 100 as a cushioning material between the outer fabric 150 of the front fabric 110 and the back fabric 120. It is also possible to configure.

In particular, in the main body belt portion 51, by providing the three-dimensional network structure 100 as a cushioning material, it is lighter and has higher air permeability than urethane and polyolefin-based foams, and can reduce moisture and the like. It becomes possible to keep it.
That is, since the three-dimensional network structure 100 is excellent in air permeability, air passages are formed, and the volume of the space in the three-dimensional network structure 100 is also changed by the movement of the user M, so that the air flow. Is promoted, moisture and heat are less likely to stay, and stuffiness can be reduced.

  In particular, if the whole or part of the three-dimensional network structure 100 is covered with a breathable fabric, fresh air is taken in and moisture and heat are likely to escape. In addition, due to the high porosity of the three-dimensional network structure 100, the movement of the user M has a volume that can accommodate the moisture generated by the user M such as sweat, but the movement of the user M is three-dimensional network structure. Since the air in the air layer changes in volume in 100 and the air in the air layer is discharged and supplied, the sweat sweated from the body of the user M or the infant B can be quickly absorbed through the breathable fabric, Further, the moisture and heat of the body of the user M and the infant B can be released. Therefore, moisture and heat are not accumulated in the three-dimensional network structure 100, and heat and stuffiness can be reduced, and even when used for a long time, the body temperature is partially prevented from rising abnormally. It also becomes a countermeasure and can reduce discomfort due to the feeling of stuffiness around the waist of the user M.

  Of course, the front and back surfaces of the front and rear fabrics 110 and 120 constituting the main body belt portion 51, that is, the front and back surfaces of the main body belt portion 51, which is the surface applied to the body of the user M and the opposite surface, are air permeable. In the case where the cloth having the fabric is used, stuffiness is further reduced by increasing the air flow rate in the thickness direction due to the air permeability of the three-dimensional network structure 100 and the air permeability of the front and back fabrics.

  When the three-dimensional network structure 100 is used as a cushioning material for the main body belt portion 51 in this way, the main body belt portion 51 is excellent in air permeability and hardly retains moisture and heat. In comparison with the above, bacteria and molds are also difficult to propagate, and permeation of sweat from the user M and odors caused by the propagation of bacteria and molds can be prevented. Furthermore, according to the three-dimensional network structure 100, the continuous space is excellent in air permeability and water permeability and moisture permeability, so that it has a quick drying property. Hygiene and cleanliness can be maintained by washing without fear of breeding. Therefore, hygiene characteristics are improved. In addition, the continuous filaments 101 constituting the three-dimensional network structure 100 are made of synthetic resin, they are irregularly meandering and entangled, and are fused in a meandering state everywhere. Has the strength to withstand washing, and the cushioning properties are unlikely to deteriorate even after repeated washing.

Furthermore, the continuous linear body 101 is entangled three-dimensionally, and the pressure receiving area around the waist of the user M is widened by the arrangement of the three-dimensional network structure 100 having a continuous space, and the pressure applied to the user M is dispersed. It is easy to reduce the weight that the user M feels.
In particular, the three-dimensional network structure 100 disposed in the main body belt portion 51 preferably has a thickness in the range of 3 mm to 30 mm, more preferably in the range of 3 mm to 10 mm. And, if the hardness at 25% compression is in the range of 10 N / φ200 to 200 N / φ200 or less, it has appropriate elasticity, and around the waist of the user M without using a hard core material separately. Concentration of applied stress is avoided, and furthermore, due to the moderate softness, the waist belt portion 50 is prevented from floating, and the waist belt portion 50 fits along the curve around the waist according to the body shape of the user M Can be made. As a result, the load applied to the waist of the user M is well-distributed and the load on the waist of the user M is easily dispersed. The weight is not concentrated in a specific part, so the burden on the user M is reduced. It becomes difficult to feel. And even if it is easy to fit along the body shape of the waist of the user M by the solid network structure 100 of a predetermined hardness, the solid network structure 100 is hard to be stuffy because it has air permeability. In particular, it is possible to fit the back of a flat waist that does not bulge compared to the back and abdomen around the waist of the user M, so that the burden on the back of the waist can be reduced even when a piggyback is put on. .
In addition, according to the three-dimensional network structure 100, compared to a conventional cushioning material made of urethane or polyolefin foam, it is light in weight as an equivalent cushioning action, and the weight and carrying burden for the user M who wears it. Can be reduced.

In the case of carrying out the present invention, a core material made of hard urethane or polyolefin-based foam is disposed on the main body belt portion 51, and in order to improve contact with the body, a three-dimensional net-like shape is formed on the user M side. The structure 100 may be provided. Also by this, since the three-dimensional network structure 100 is excellent in air permeability, dampness or the like can be reduced because moisture and heat hardly stay. Further, the body pressure is dispersed by the three-dimensional network structure 100, and the burden on the user M can be reduced.
In addition, the connection of the waist belt portion 50 to the main body portion 10 and the auxiliary support portion 20 may be sewing, or may be a structure that can be attached and detached by an engaging means or the like.

Furthermore, in the baby carrier 1 of the present embodiment, the auxiliary holding portion 20 is sewn to the waist belt portion 50 together with the main body portion 10.
The auxiliary holding portion 20 is disposed on the infant B side of the main body portion 10, and the lower end portion thereof is integrally attached to the waist belt portion 50 together with the main body portion 10. Otherwise, the auxiliary holding portion 20 is separable from the main body portion 10. It is applied to the body of the infant B on the opposite side to the main body 10. When the infant B is held with a face-to-face hug or a forward-facing piggyback, the infant B is applied to the opposite back side, that is, the crotch side or the abdomen side.

  In the figure, the auxiliary holding part 20 is sewn to the waist belt part 50 together with the body part 10 inwardly of the connecting lateral width of the body part 10 and the waist belt part 50, and the other end side of the free end extending upward. It has a substantially trapezoidal shape that is gradually widened toward. The relationship between the auxiliary holding part 20 and the waist belt part 50 is also arranged in a substantially inverted T shape as a whole, and is integrally connected to the waist belt part 50 by sewing only the lower end of the auxiliary holding part 20. The auxiliary holding part 20 is also bendable in a direction perpendicular to the surface direction.

In the present embodiment, the three-dimensional network structure 100 as a cushioning material is also disposed in the auxiliary holding portion 20 applied to the body of the infant B on the side opposite to the main body portion 10.
Also here, the three-dimensional network structure 100 as a cushioning material is covered with an exterior fabric 150 composed of a front fabric 110 and a back fabric 120 to constitute the auxiliary support portion 20. That is, the auxiliary support portion 20 is configured by placing the three-dimensional network structure 100 as a cushioning material in an exterior fabric 150 composed of a front fabric 110 and a back fabric 120 closed in a bag shape. Thereby, the auxiliary support part 20 has predetermined softness | flexibility, flexibility, elasticity, etc., and prevents the infant B's body shape from being forced.
Further, in the auxiliary holding unit 20, a part or all of the outer fabric 150 on the infant B side or the user M side, or both of the outer fabrics 150 on the front and back sides, is used.

  As described above, in the baby carrier 1 of the present embodiment, the auxiliary holding part 20 applied to the body of the infant B on the opposite side to the main body part 10 is provided, and air permeability is provided between the infant B and the user M to be held. By disposing the three-dimensional network structure 100 covered with the cloth having the air, an air passage is formed between the infant B and the user M, and moisture and heat are easily escaped, so that an abnormal heat retention state is not reached. Also, the movement of the infant B or the user M causes a change in volume of the space (air layer) of the three-dimensional network structure 100, so that an air flow is generated, and fresh air is supplied and air with high humidity or heat is generated. Emissions are promoted. Furthermore, even when moisture such as sweat is generated, the three-dimensional network structure 100 has a volume capable of accommodating the moisture, and sweat sweated from the body of the user M or the body of the infant B is quickly absorbed. Since the space of the three-dimensional network structure 100 is continuous, the absorbed moisture is easily dissipated to the outside, and moisture and heat are not easily stored. Therefore, the heat and stuffiness due to the close contact of the user M and the infant B are remarkably reduced, and it is also a countermeasure against sweating and a sweat rash. When the infant B is held, a sticky feeling and a jerky feeling do not occur. Furthermore, even if the body shapes and movements of the infant B and the user M change, there is no sense of incongruity due to the follow-up change of the auxiliary holding unit 20. In addition, since the auxiliary holding part 20 is interposed between the user M and the infant B, it is possible to prevent wrinkles caused by the body temperature of the infant B from entering the clothing of the user M. Moreover, even if the exterior fabric 150 covering the three-dimensional network structure 100 does not have air permeability, if the density of the continuous filaments 101 is increased, air is retained and a heat insulating effect is obtained.

Since the three-dimensional network structure 100 has air permeability and is difficult to retain moisture and heat in this way, the continuous filaments 101 are formed by irregularly meandering entanglements of the continuous filaments 101 made of synthetic resin. Since most of them are loop-like and it is difficult to produce synthetic resin waste, bacteria and molds are difficult to propagate, and permeation of sweat from infant B and user M and odors caused by the propagation of bacteria and molds can be prevented. Furthermore, because it has excellent air permeability and moisture permeability due to continuous space, it has quick-drying properties, so even if you wash it, it dries quickly and there is no risk of bacteria growing before drying. Well, you can keep it clean. In addition, the continuous filaments 101 constituting the three-dimensional network structure 100 are made of synthetic resin, they are irregularly meandering and entangled, and are fused in a meandering state everywhere. Has the strength to withstand washing, and the cushioning properties are unlikely to deteriorate even after repeated washing.
In addition, a comfortable holding feeling can be obtained by appropriate cushioning properties of the three-dimensional network structure 100.

The three-dimensional network structure 100 disposed in the auxiliary holding unit 20 has a thickness of 3 mm or more and 20 mm or less, more preferably 3 mm or more and 10 mm or less. And is flexible and soft enough to be bent in accordance with the body shape of the infant B or the user M, and is less bulky when being carried.
The 25% compression hardness of the three-dimensional network structure 100 disposed in the auxiliary holding part 20 is preferably in the range of 10 N / φ200 or more and 150 N / φ200 or less, more preferably 10 N / φ200 or more, 130 N. / Φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 20 kg / φ150, more preferably 3 kg / φ150 to 10 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 5 kg / φ150 to 25 kg / φ150.
If it is in the above-mentioned range, the solid network structure 100 follows the movements of the infant B and the user M, is familiar with the body shape, and does not feel uncomfortable between the infant B and the user M, such as a sense of incongruity. A feeling can be secured.

  In addition, in the baby carrier 1 of the present embodiment, a predetermined length of cloth having a connecting plug 23 of a buckle with an adjuster at the front end via a connecting cloth 25 at both left and right ends of the auxiliary holding part 20 on the free end side. A pair of left and right connection adjusting portions 22 made of belts are attached, and the connection insertion tool 23 is located near the boundary between the backrest portion 12 and the abutment portion 13 on the left and right sides of the main body portion 10 on the infant B side (outer surface side). A buckle connection receiver 24 corresponding to the engagement is attached, and the left and right side portions on the free end side of the auxiliary holding portion 20 and the main body portion 10 by the connection engagement of the connection insertion tool 23 and the connection receiver 24. A connecting portion 21 having a predetermined length is formed to connect the left and right sides near the boundary between the backrest portion 12 and the abutment portion 13 (see FIG. 6).

  Therefore, in the baby carrier 1 of the present embodiment, the auxiliary holding portion 20 sewn to the waist belt portion 50 together with the main body portion 10 on the infant B side (inner surface side) of the main body portion 10 is connected and adjusted on both right and left sides. The distance between the main body part 10 and the auxiliary holding part 20 by being connected to the main body part 10 by the connection part 21 having a predetermined length formed by the connection engagement of the part 22 and the connection plug 23 and the connection receiver 24 ( Distance) is fixed, and the infant B is positioned in a space formed between the main body 10, the auxiliary holding part 20 and the connection part 21. Thus, the infant B is accommodated between the main body part 10, the auxiliary holding part 20, and the connection part 21, and the main body part 10 is applied to the back side of the infant B in the face-to-face hug and the forward facing piggyback. The auxiliary holding part 20 is assigned to the abdominal side, and the infant B is held by the connecting part 21 so as not to fall sideways. In particular, the leg of the infant B is passed through the annular opening formed between the left and right side edges of the main body 10 and the left and right side edges of the auxiliary holding part 20 below the connection part 21. The situation where the infant B falls from the side of the head rest 11 of the main body 10 due to the bowing of the infant B due to the restriction of the accommodation space of the infant B or the user M's forward bending posture, etc. Can be prevented. Further, even when the position of the baby B is moved with respect to the user M by switching the holding and the piggyback, the infant B can be prevented from falling and the user M can easily switch the holding and the piggyback even if not skilled. And

Furthermore, in the baby carrier 1 of the present embodiment, a pair of left and right shoulder belt portions 40 are sewn to the free end side of the auxiliary holding portion 20.
The one pair of left and right shoulder belt portions 40 are firmly attached to the left and right of the upper end portion on the free end side of the auxiliary holding portion 20 by sewing, and the other end portions are upper portions on the free end side of the auxiliary holding portion 20. It is firmly attached to the left and right side parts of the sewing machine via a connecting fabric 25 by sewing. That is, the shoulder belt portion 40 of the present embodiment is passed in the vertical direction of the auxiliary holding portion 20.

  The pair of left and right shoulder belt portions 40 are directly or indirectly connected to the auxiliary holding portion 20 and the main body portion 10 to receive much of the weight of the infant B, so that the shoulder belt portion 40 can withstand the strength of the user M. As a form in which force (the weight of the infant B) is distributed so as not to overwhelm the user M's body shape even if it is mounted around, it is integrally connected to the upper end on the free end side of the auxiliary holding part 20 and wide in width. A shoulder portion 41 and an adjustment belt portion 42 attached to the other end of the shoulder portion 41 and connected to the left and right side portions of the upper portion of the auxiliary holding portion 20 on the free end side.

  Since the shoulder portion 41 is hung on the left shoulder or the right shoulder of the user M, the shoulder portion 41 is formed of a material having predetermined flexibility, flexibility, etc. This increases the burden on the user M. For example, a cushioning material may be inserted between the outer fabric 110 and the outer fabric 150 of the back fabric 120 so that a part of the back of the user's M shoulder or neck does not cause the infant B to concentrate on the weight. . Also, the shoulder portion 41 can be used as a whole or a part of the exterior fabric 150 with a breathable fabric to prevent moisture such as stuffiness and to reduce discomfort. Furthermore, the hygroscopicity is improved also by forming at least the inner surface side of the user M that touches the shoulder of the user M with a cotton fabric having water absorption.

When practicing the present invention, the outer fabric 150 of the front fabric 110 and the back fabric 120 is composed of a core material made of hard urethane or polyolefin foam as a cushioning material and a soft urethane or polyolefin foam. The shoulder portion 41 can be formed using a cushion material, and the three-dimensional network structure 100 can be used as a cushioning material.
By disposing the three-dimensional network structure 100 as a cushioning material in the shoulder portion 41, it is lighter and more breathable than urethane and polyolefin foams, and can reduce stuffiness and maintain hygiene. It becomes possible.

  That is, since the three-dimensional network structure 100 is excellent in air permeability, air passages are formed, and the volume of the space in the three-dimensional network structure 100 is also changed by the movement of the user M, so that the air flow. Is promoted, moisture and heat are less likely to stay, and stuffiness can be reduced.

  In particular, if the whole or part of the three-dimensional network structure 100 is covered with a breathable fabric, fresh air is taken in and moisture and heat are likely to escape. In addition, due to the high porosity of the three-dimensional network structure 100, the movement of the user M has a volume that can accommodate the moisture generated by the user M such as sweat, but the movement of the user M is three-dimensional network structure. Since the air in the air layer changes in volume in 100 and the air in the air layer is discharged and supplied, the sweat sweated from the body of the user M or the infant B can be quickly absorbed through the breathable fabric, Further, the moisture and heat of the body of the user M and the infant B can be released. Therefore, moisture and heat are not accumulated in the three-dimensional network structure 100, and heat and stuffiness can be reduced, and even when used for a long time, the body temperature is partially prevented from rising abnormally. As a countermeasure, it is possible to reduce discomfort due to the feeling of stuffiness around the shoulder of the user M.

  Needless to say, the fabric having air permeability on both sides of the front fabric 110 and the back fabric 120 constituting the shoulder portion 41, that is, on the front and back surfaces of the shoulder portion 41 with the surface applied to the body of the user M and the opposite surface. Is used, the amount of air flow increases in the thickness direction due to the air permeability of the three-dimensional network structure 100 and the air permeability of the front and back fabrics, thereby further reducing moisture.

  When the three-dimensional network structure 100 is used as a cushioning material for the shoulder portion 41 in this way, the shoulder portion 41 is excellent in air permeability and hardly retains moisture and heat. Thus, bacteria and molds are also difficult to propagate, and the permeation of sweat from the user M and the odor caused by the propagation of bacteria and molds can be prevented. Furthermore, according to the three-dimensional network structure 100, the continuous space is excellent in air permeability and water permeability and moisture permeability, so that it has a quick drying property. Hygiene and cleanliness can be maintained by washing without fear of breeding. Therefore, hygiene characteristics are improved. In addition, the continuous filaments 101 constituting the three-dimensional network structure 100 are made of synthetic resin, they are irregularly meandering and entangled, and are fused in a meandering state everywhere. Has the strength to withstand washing, and the cushioning properties are unlikely to deteriorate even after repeated washing. In addition, even when the baby B is drooling or adhering to the vomit, the moisture dries quickly and can prevent the growth of bacteria and mold.

Furthermore, the continuous linear body 101 is entangled three-dimensionally, and the pressure receiving area around the shoulder and back of the user M is widened by the arrangement of the three-dimensional network structure 100 having a continuous space. It is easy to be dispersed, and the weight felt by the user M can be reduced.
In particular, the three-dimensional network structure 100 disposed in the shoulder portion 41 preferably has a thickness in the range of 3 mm to 30 mm, more preferably in the range of 3 mm to 10 mm. And if the hardness at 25% compression is in the range of 10 N / φ200 to 200 N / φ200 or less, it has appropriate elasticity and around the shoulder of the user M without using a hard core material separately. Concentration of applied stress is avoided, there is little bite, and because there is moderate softness, familiarity is easy and the load applied around the shoulder of the user M is easily dispersed, and the weight does not concentrate in a specific place The burden on the user M is reduced and it becomes difficult to feel discomfort such as pain and stiff shoulders even when worn for a long time. And even if it is easy to fit along the body shape around the shoulder of the user M by the three-dimensional network structure 100 having a predetermined hardness, the three-dimensional network structure 100 is less stuffy because it has air permeability.

In addition, according to the three-dimensional network structure 100, compared to a conventional cushioning material made of urethane or polyolefin foam, it is light in weight as an equivalent cushioning action, and the weight and carrying burden for the user M who wears it. Can be reduced.
When carrying out the present invention, a core material made of hard urethane or polyolefin-based foam is disposed on the shoulder portion 41, and a three-dimensional network structure is formed on the user M side in order to improve contact with the body. It is good also as a structure which arrange | positions the body 100. FIG. Also by this, since the three-dimensional network structure 100 is excellent in air permeability, dampness or the like can be reduced because moisture and heat hardly stay. Further, the body pressure is dispersed by the three-dimensional network structure 100, and the burden on the user M can be reduced.

In the figure, the adjustment belt portion 42 connected to one end portion of the shoulder portion 41 is a belt made of a cloth belt having a predetermined length so that a belt length necessary for mounting around the shoulder of the user M is determined. It is comprised from the part 42a, the adjuster 42b arrange | positioned by the side connected to the shoulder part 41, and the adjuster 42c arrange | positioned by the connection side to the right-and-left side part of the auxiliary | assistant holding | maintenance part 20.
Thus, the adjuster 42b is attached to one end side in the length direction of the belt portion 42a having a predetermined length, and the adjuster 42c is attached to the other end side, so that the belt length can be adjusted, and the shoulder belt portion. The length of 40 can be hung on the shoulder of the user M and adjusted to the length around the shoulder that is turned backward.

  Further, a rotation type buckle connection plug 43 for connecting to the main body 10 is attached to the shoulder portions 41 of the pair of left and right shoulder belt portions 40. The connecting plug 43 is attached to the distal end of the connecting portion 14 projecting from the left and right sides near the boundary between the head support portion 11 and the back support portion 12 on the infant B side (inner surface side) of the main body portion 10. The shoulder belt portion 40 and the main body portion 10 are connected to each other by the coupling insertion tool 43 and the coupling receptacle 44 of the rotary buckle and the connection portion 14 by the coupling engagement with the coupling receptacle 44 of the rotary buckle. Unless the buckle is disengaged, the connection state of the shoulder belt portion 40 and the main body portion 10 is fixed, and the infant B accommodated between the main body portion 10 and the auxiliary support portion 20 can be held.

  Furthermore, the shoulder belt portion 41 of the present embodiment is provided with a shoulder belt adjustment portion 46 that adjusts and holds the distance between the left and right shoulder belt portions 40. The shoulder belt adjusting portion 46 has a buckle connecting plug 46c attached to the tip of an adjustment belt portion 46a of a predetermined length attached to a shoulder hanging portion 41 that is hung on the left shoulder via a belt moving adjuster 48, and a right shoulder. A buckle connecting receiver 46d is attached to the shoulder hanging portion 41 through a belt movable adjuster 48 and a belt cloth 46b so that the connecting plug 46c and the connecting receiver 46d can be engaged with each other. Then, by adjusting the belt length by the adjustment belt portion 46a attached to the adjuster of the buckle connection plug 46c, the connection length of the shoulder belt adjustment portion 46 connecting the left and right shoulder belt portions 40 is adjusted, and the right and left The distance (distance) between the shoulder belt portions 40 can be adjusted. In the case of carrying out the present invention, the adjuster function may be provided for both the connection plug 46c and the connection receiver 46d, or only one of them may be provided, or the adjuster function may be made independent.

  As a result, in the state where the left and right shoulder belt portions 40 are hung on the shoulders, the connection insertion tool 46c of the shoulder belt adjustment portion 46 and the connection receiver 46d are connected and engaged, so that the distance between the left and right shoulder belt portions 40 is increased. It is fixed and can maintain a predetermined distance, and the left and right shoulder belt portions 40 will not come off the shoulder. In addition, by adjusting the belt length by the belt length by the adjustment belt portion 46a attached to the adjuster, a fulcrum that supports the weight of the infant B is used according to the body shape, usability, preference, how to hold the infant B, etc. It can be adjusted to a position with less burden on the person M. Therefore, even a person with a stiff shoulder can reduce the burden on the shoulder.

In addition, the shoulder belt adjustment portion 46 of the present embodiment is slid through a belt movable adjuster 48 having belt passing portions in four directions with respect to a slide belt 47 disposed along the surface of the shoulder portion 41. The shoulder belt adjusting portion 46 is movable on the surface of the shoulder portion 41.
Therefore, even when the pair of left and right shoulder belt portions 40 are hung on the shoulder of the user M, the position of the shoulder belt adjustment portion 46 is moved to connect the connection insertion tool 46c and the connection receptacle 46d of the shoulder belt adjustment portion 46. The position of engagement can be adjusted to an optimum position that is easy for the user M to operate the coupling engagement. Further, the fulcrum supporting the weight of the infant B can be adjusted to a position with less burden on the user M according to the body shape, convenience, preference, how to hold the infant B, and the like. This also reduces the burden on the shoulder for those who are stiff.
Incidentally, when the present invention is carried out, the means for adjusting or fixing the distance (distance) between the left and right shoulder belt portions 40 is limited to that by connection of the buckle or sliding of the buckle. There is nothing. Moreover, these functions may be performed by one member or may be performed by separate members.

  In the figure, the baby B is accidentally engaged with the buckle by covering the connecting plug 43 attached to the shoulder 41 of the shoulder belt 40 with the covering cover 45 attached to the shoulder 41. It prevents it from being released. Further, the buckle formed of plastic is prevented from being deteriorated by ultraviolet rays or the like. Furthermore, even if the lip of the infant B hits the shoulder portion 41 and thereby the lips of the infant B are stimulated and the shoulder belt portion 40 may be licked, by covering with the covering cover 45 attached to the shoulder portion 41, The buckle will not injure infant B's lips and tongue.

  In the baby carrier 1 of the present embodiment, the baby carrier 1 is further provided between the main body 10 and the auxiliary holding part 20 and is arranged between the main body 10 and the auxiliary holding part 20 by adjusting the length to be folded in the length direction. It has a positioning seat 30 that allows the depth of the child 10 to be freely adjusted and positions the sinking depth of the buttocks of the infant 10. Since the positioning seat portion 30 is also directly applied to the body of the infant B, it is formed of a material having predetermined flexibility and flexibility.

  In the figure, the positioning seat portion 30 is integrally extended from the vicinity of the boundary between the backrest portion 12 and the abutment portion 13 of the main body portion 10 and gradually narrowed toward the center side, and then the other end on the opposite side. The second abutment part 31 applied to the buttocks of the infant 10 when holding the infant B with a face-to-face holding or a front-facing piggyback, and a constant from the second buttocks abutment part 31 The length adjustment part 32 is formed by extending integrally with the width and allowing the length dimension to be adjusted.

  The length adjusting portion 32 integrally formed from the second abutment portion 31 is formed with a constant lateral width, and its length dimension is on the back side opposite to the opposing side of the main body portion 10 and the auxiliary holding portion 20. A pair of female sides 33a and a male side 33b of a slide-type fastener 33 as an adjustment tool for making adjustment possible, and the pair of female sides 33a and the male side 33b of the slide-type fastener 33 have a predetermined distance. Installed, apart.

  Therefore, the length between the female side 33a and the male side 33b is closed by closing the pair of the female side 33a and the male side 33b of the slide-type fastener 33 that are separated by a predetermined distance in the length adjusting unit 32. The length of the positioning pedestal 30 that is fixed in the folded state and connects between the main body 10 and the auxiliary holder 20 is shortened. On the other hand, when the engagement of the pair of female side 33a and male side 33b of the sliding fastener 33 is released, the folding is unfolded, and the positioning pedestal portion 30 has the original length and the main body portion 10 and the auxiliary holding portion 20. Connect between.

  Thus, when the infant B is disposed between the main body 10 and the auxiliary holding portion 20, a pair of female sides 33a of the sliding fastener 33 of the positioning base portion 30 that passes between the main body 10 and the auxiliary holding portion 20 is provided. In the state where the male side 33b is not engaged, the length of the positioning pedestal 30 disposed between the main body 10 and the auxiliary holding portion 20 is long. The infant B, which is housed between the main body 10 and the auxiliary holding part 20 and has the buttocks received by the positioning pedestal 30, has a deepened sinking depth. That is, the buttocks of the infant B are positioned at a low position.

  On the other hand, in the engagement state in which the pair of female sides 33a and the male side 33b of the sliding fastener 33 of the positioning base 30 passing between the main body 10 and the auxiliary holding unit 20 are closed together, a pair of female sides Since the length between 33a and the male side 33b is folded and the connection length of the positioning pedestal portion 30 connecting the main body portion 10 and the auxiliary holding portion 20 is shortened, the positioning pedestal portion 30 causes the main body portion to be shortened. 10 and the auxiliary holding part 20 is raised in depth, and the infant B, which is accommodated between the main body part 10 and the auxiliary holding part 20 and is received by the positioning pedestal 30, has a shallow sinking depth. Become. In other words, the buttocks of the infant B are positioned at a high position.

  Therefore, according to the baby carrier 1 of the present embodiment, when the infant B to be held is low in height, the slide of the positioning pedestal 30 disposed between the main body 10 and the auxiliary holder 20 is arranged. By engaging the pair of female side 33a and male side 33b of the type fastener 33 and shortening the connection length between the main body part 10 and the auxiliary holding part 20 in the positioning pedestal part 30, Since the sink is positioned at a high position, even if the infant B to be held is short, the head of the infant B does not become a low position in the positional relationship between the main body 10 and the infant B, and the head of the infant B is the head. The baby B is stably placed in a comfortable posture with less burden, without being placed in the body 11 and the body 20 and the auxiliary holder 20 so that the body of the baby B sinks.

  When the infant B to be held is tall, that is, when the infant B becomes large due to growth, the pair of female side 33a and male side 33b of the sliding fastener 33 is disengaged, By developing the connection length between the main body part 10 and the auxiliary holding part 20 to the original length in the positioning pedestal part 30, the sinking of the buttocks of the infant B is positioned at a low position. On the other hand, the head support part 11, the back support part 12, and the buttocks support part 13 of the main body part 10 are applied at appropriate positions, and the infant B is stably held in a comfortable posture with less burden.

Further, in the case where the infant B is mounted on the back side of the user M facing forward in the same direction as the user M, the length of the positioning pedestal 30 that connects between the main body 10 and the auxiliary holding unit 20 is shortened. Since the position of the buttocks of the infant B can be increased, the position of the infant B can be held at a position farther from the position of the waist of the user M, so that the spine of the user M and the spine of the infant B are repelled. As a result, the shape of the curved spine line of the infant B tends to follow the shape of the curved spine line of the user M, and the infant B easily adheres to the user M. Therefore, it is possible for the user M and the infant B to hold comfortably with a comfortable posture. In particular, the user M carrying the infant B is less likely to feel the weight of the infant B than the baby and can easily hold it. In addition, since the infant B easily comes into close contact with the user M, the infant B is unlikely to be warped backward.
Even when the buttocks of the infant B are landed on the positioning pedestal portion 30 whose original length is between the main body portion 10 and the auxiliary holding portion 20 and is placed at a low position, the auxiliary holding portion 20 and the main body portion 10 are also disposed. Are connected by the connection part 21 and the leg of the infant B is passed through the ring formed by the auxiliary holding part 20, the main body part 10 and the connection part 21, so that the infant B can be prevented from falling due to warping.

  Since the positioning seat portion 30 is also applied to the body of the infant B, it is formed of a material having predetermined flexibility, flexibility, and the like. For example, the exterior fabric 150 of the front fabric 110 and the back fabric 120 is used. By forming a cushioning material between the two, the baby B can comfortably hold and sit comfortably. For example, in the second abutment portion 31 applied to the buttocks of the infant 10, the three-dimensional network structure 100 is disposed between the front fabric 110 and the back fabric 120 constituting the infant 10, so that the infant B The buttocks can be received softly, the depression of the buttocks can be facilitated, the center of gravity position of the infant B can be stabilized and the holding stability can be enhanced. And even when hold | maintaining for a long time, the fitting property to the buttocks of the infant B is high, and it becomes comfortable seating by the pressure applied to the buttocks being dispersed, and the burden on the buttocks of the infant B is reduced.

The 25% compression hardness of the three-dimensional network structure 100 disposed in the positioning seat 30 is preferably in the range of 10 N / φ200 or more and 150 N / φ200 or less, more preferably 10 N / φ200 or more, 130 N. / Φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 20 kg / φ150, more preferably 3 kg / φ150 to 10 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 5 kg / φ150 to 25 kg / φ150.
If it is within the above range, the lower part of the buttocks of the infant B can be easily lowered, the center of gravity of the buttocks can be stabilized to prevent the position shift, thereby obtaining a stable sinking of the infant B and improving the holding stability. It is possible to hold in a comfortable posture with less burden on M and infant B. Moreover, even if it touches the leg of the infant B, it follows it, and the movement of the leg of the infant B is difficult to be restricted. In particular, even when holding an infant B of a young age before the neck is set, the knee of the infant B is easily bent down, so that the knee is bent at a position higher than the position of the buttocks of the infant B, and an M-shaped spread leg is formed. In a natural open leg posture, the center of gravity of the infant B is not on the leg side but on the buttocks, and the body shape of the infant B can be held with a low burden.

  In the baby carrier 1 according to the present embodiment, the portion applied to the buttocks of the body of the infant B on the side opposite to the infant B as the holding section applied to the body of the infant B is the abutment portion 13 of the main body 10 and the positioning seat portion. 30 second latching portions 31, but either the latching portion 13 or the second latching portion 31, or both the latching portion 13 and the second latching portion 31 have a three-dimensional network structure. By disposing 100, the buttocks of the infant B easily fall down, the center of gravity of the infant B is stabilized, and the holding stability is improved. Moreover, the pressure applied to the buttocks of the infant B is easily dispersed, the sitting comfort is improved, and the burden on the infant B is reduced. Of course, the sitting comfort of the infant B is improved by providing the three-dimensional network structure 100 also in the length adjusting unit 32. However, in the baby carrier 1 of the present embodiment, in the state where the length adjustment unit 32 is lengthened, it overlaps with the auxiliary holding unit 20 and is applied to the crotch side of the infant B's body. In the case where the three-dimensional network structure 100 is disposed on the positioning seat portion 30, only a portion that is applied to the buttocks of the infant B may be provided in consideration of the bulkiness of the crotch side of the infant B, the unevenness, and the like. Of course, when the three-dimensional network structure 100 is disposed on the positioning seat 30 according to the purpose of the baby carrier 1 or the like, it is possible to provide a partial arrangement of only the portion applied to the crotch side of the infant B. .

In particular, since the three-dimensional network structure 100 has high air permeability, even if it is in close contact with the buttocks of the infant B, it is difficult to get stuffy, and diaper rashes are hardly caused. In addition, as described above, hygienic characteristics are also improved.
And in this positioning seat part 30, since it will be applied directly to the infant B, the moisture, such as stuffiness, is prevented by using the cloth which has air permeability for the exterior cloth for the whole or a part. And discomfort can be reduced. Also, the hygroscopicity is improved by forming at least the upper surface side (surface side) in contact with the infant B with a cotton fabric having water absorption.

Note that the length adjustment unit 32 that can be folded is also flexible and flexible enough to be folded, and elastic and buffered so that the infant B does not feel uncomfortable or uncomfortable. Alternatively, the three-dimensional network structure 100 may be disposed with a small thickness.
The positioning seat 30 is formed of a material having a low elasticity that does not stretch or elastically deform due to an elastic force acting in the direction of gravity when an external force receiving the weight of the infant 10 is applied.

  As described above, the baby carrier 1 according to the present embodiment includes the main body 10, the auxiliary holding unit 20, and the positioning as a holding unit that holds the baby B by holding or holding the baby B by the body of the baby B. In the baby carrier 1 having the portion 30, the main body portion 10, the auxiliary holding portion 20, and the positioning portion 30 as a holding portion for holding the infant B are configured by an exterior fabric 150 and a cushioning material wrapped in the exterior fabric 150. The material is a continuous three-dimensional network 101 made of synthetic resin that is irregularly meandered and entangled, and is fused in a meandering state, and the space between the continuous filaments 101 communicates with each other. The structure 100 is formed.

  That is, the baby carrier 1 according to the present embodiment is disposed on the main body 10, the auxiliary holding part 20, and the positioning part 30 as a holding part that is applied to the body of the infant B and holds the infant B. The cushioning material placed in the exterior fabric 150 made up of one front fabric 110 and the other back fabric 120 opposite the front fabric constituting the main body portion 10, the auxiliary holding portion 20, and the positioning portion 30 is made of a synthetic resin. The continuous filaments 101 are irregularly meandering and intertwined, and are fused in a meandering state, and the space between the continuous filaments 101 communicates with each other so as to have a breathable three-dimensional network structure. 100.

Therefore, according to the baby carrier 1 according to the present embodiment, when an external force is applied due to the arrangement of the three-dimensional network structure 100, the curvature of curvature of the curved continuous filament 101 constituting the same changes, When the space between the continuous filaments 101 is deformed and the external force is released, the continuous filaments 101 return to the original curvature, and the cushioning property (elasticity) for restoring the space is excellent. In particular, since the continuous filaments 101 are fused together, the pressure receiving area is wide, and when an external force is applied, the entire three-dimensional network structure 100 is deformed, and the user M and infants with a small sinking depth. Supports the body of B, disperses the pressure applied to the body evenly, and has a cushioning property with little bottom feeling even if the thickness is thin.
Moreover, the space between the continuous filaments 101 constituting the three-dimensional network structure 100 communicates with each other, and the air permeability is excellent. Therefore, moisture and heat hardly stay, heat can be reduced, and the occurrence of stuffiness can be prevented.
Therefore, a comfortable holding feeling for the infant B is obtained, and the burden on the infant B is reduced even when used for a long time.

  And since moisture and heat do not easily stay in the three-dimensional network structure 100 in this way, it is difficult for bacteria, fungi, etc. to propagate, and furthermore, the space between the continuous striatal bodies 101 communicates with each other so that air permeability and water permeability can be obtained. And the moisture content dries quickly, and the continuous filaments 101 constituting the three-dimensional network structure 100 are made of a synthetic resin. They are irregularly meandered and intertwined, and in a meandering state everywhere. Since it is fused to each other, it has strength to withstand repeated washing, and characteristics such as cushioning properties are unlikely to deteriorate even after repeated washing. Therefore, hygiene and cleanliness can be maintained.

  In particular, when a part or all of the exterior fabric 150 including the cushioning material made of the three-dimensional network structure 100 is formed into mesh-like fibers that allow air to enter and exit, the continuous filaments constituting the three-dimensional network structure 100 are formed. By supplying fresh air to the space between the bodies 101 and discharging the air held in the space between the continuous filaments 101, moisture and heat from the infant B and the user M can easily escape. A partial increase in body temperature can be prevented, and stuffiness can be further prevented. In addition, hygiene characteristics are improved. Furthermore, by making the fabric into a mesh structure having a mesh structure or a plurality of ventilation holes, flexibility and stretchability are also increased, and the fit and familiarity with the body shape and movement of the infant B and the user M are improved. In addition, since the weight is reduced, the burden on the user M is also reduced.

In this way, according to the baby carrier 1 according to the present embodiment, it is cushioned, but it is difficult to stuffy and can be held comfortably, and even if the baby B is held for a long time, the baby B can be less tired. In addition, hygienic characteristics are improved.
Further, even if the head hood is used, moisture and heat are difficult to be stored, which is advantageous for laying on the bed, and the infant B who is sleeping is prevented from sweating excessively, and a comfortable sleeping environment can be created.
In addition, since the three-dimensional network structure 100 has high air permeability and moisture and heat are not easily trapped in the cushioning material, the heat is reduced and the stuffiness is reduced. Thus, affected areas such as sweat rash and atopic dermatitis can be kept hygienically, deterioration can be prevented, and their onset can be prevented.
In addition, because the three-dimensional network structure 100 communicates with the gap, moisture can not be accumulated even when sprayed with deodorizing alcohol or a disinfecting spray, so that cleanliness and hygiene can be maintained.

  And in the holding | maintenance part which is applied to the infant's B body and hold | maintains the infant B, the three-dimensional network structure 10 is arrange | positioned in the main-body part 10 applied to the infant's B body on the opposite side to the user M side. Thus, compression, shaking and impact are alleviated by the three-dimensional network structure 100 which is supported on a large area with respect to the body of the infant B, and the posture of the infant B is not burdened even when used for a long time. However, it is difficult for moisture and heat such as sweat from the infant B to accumulate in the three-dimensional network structure 100, so that the heat and stuffiness of the infant B can be effectively prevented, and the comfort for the infant B becomes higher. .

Here, in the main body 10 as a holding unit that holds the infant B by being applied to the body of the infant B, the body B is applied to the head of the body of the infant B when holding the infant B with a face-to-face holding or a forward facing piggyback. If the hardness and repulsive force of the three-dimensional network structure 100 disposed on the head support 11 as a part is too small, the neck and head of the infant B may sway, or the head may hang backwards during sleep, etc. Therefore, a separate core material is required. On the other hand, if it is too large, the hit on the body becomes stronger.
According to the experimental study by the present inventors, the hardness at the time of 25% compression (stress when the three-dimensional network structure 100 is compressed to 75% with a 200 mm diameter circular compression plate and then compressed again by 25%). 10 N / φ200 or more and 180 N / φ200 or less, more preferably 10 N / φ200 or more and 130 N / φ200 or less, and a three-dimensional network structure 100 having a thickness of 20 mm is formed into a circular compression plate having a diameter of 150 mm. The load is applied to 5 mm (compression rate 25%), and the applied force (repulsive force) when submerged 10 mm (compression rate 50%). The compression rate 25% (push-in amount 5 mm) The repulsive force at the time is in the range of 3 kg / φ150 or more and 15 kg / φ150 or less, more preferably in the range of 4 kg / φ150 or more and 10 kg / φ150 or less, and the compression rate is 50% (indentation amount 1 0 mm), the repulsive force is preferably in the range of 5 kg / φ150 or more and 30 kg / φ150 or less, and more preferably in the range of 10 kg / φ150 or more and 30 kg / φ150 or less. The head and neck of the infant B can be supported and the impact can be reduced.

That is, the three-dimensional network structure 100 disposed at the portion applied to the head of the infant B in the holding portion that holds the infant B by being applied to the body of the infant B is 10N / φ200 or more and 180N / φ200 or less.

Therefore, accumulation of heat and moisture due to the close contact between the user M and the infant B can be prevented, and a partial increase in body temperature and stuffiness can be prevented. Accordingly, the holding comfort for the user M and the infant B can be improved.

In particular, in the baby carrier 1 of the present embodiment, the auxiliary holding part 20 and the connection part 21 can increase the effect of preventing the baby B from falling, and even if the baby is not an expert when handling a baby or a piggyback, The arrangement position of B becomes easy to understand.
However, when carrying out the present invention, the auxiliary holding part 20 is not necessarily required and can be omitted.

That is, when carrying out the present invention, the holding part for holding the infant M may be only the main body part 10 applied to the body of the infant B on the side opposite to the user M holding the infant B, or the infant B The body 10 applied to the body of the infant B on the side opposite to the user M side holding the child and the auxiliary holding part 20 applied to the body of the infant B on the side opposite to the body 10 side, that is, the user M side. May have.
When the holding part that holds the infant M is configured only by the main body part 10, the three-dimensional network structure 100 as a cushioning material is disposed in the main body part 10, but the holding part that holds the infant M. When the part is constituted by the main body part 10 and the auxiliary holding part 20, the three-dimensional network structure 100 may be arranged on both the main body part 10 and the auxiliary holding part 20, or the arrangement of the three-dimensional network structure 100 Only one of the main body part 10 and the auxiliary holding part 20 may be provided.

  Further, when the present invention is implemented, the waist belt portion 50 is not necessarily required and can be omitted, and an opening through which the leg of the infant B is put out in a holding form in which the infant B does not fall is formed. However, it is also possible to support the weight of the infant B with only the left and right shoulder belt portions 40 and hold or carry the infant B.

  In the figure, the shoulder belt portion 40 is connected to the auxiliary holding portion 20. However, when the present invention is carried out, the shoulder belt portion 40 is provided only on the main body portion 10 as long as the infant B can be held. May be connected, or the shoulder belt portion 40 may be connected to the main body portion 10 and the auxiliary holding portion 20. In any case, it may be configured to be connected to a position that does not interfere with the body of the infant B and to form a ring through which the shoulder of the user M is passed.

Moreover, in the said embodiment, although it was description about the baby carrier 1 of the form which hold | maintains the infant B in the vertical holding, when implementing this invention, it has the holding form of the side holding the baby B laid down. Berry carrier 1 may be used. It should be noted that the shoulder belt portion 40 is usually worn by sashing on the side. Moreover, the structure which enables the holding form of both vertical holding and horizontal holding may be sufficient.
In particular, when the three-dimensional network structure 100 is disposed in the holding portion that applies the back side of the infant B when holding it sideways, the back side of the body of the infant B laid sideways is supported from multiple directions, The pressure dispersion effect is high, vibrations and the like can be absorbed, and the burden on the infant B can be reduced even when held for a long time.

Furthermore, when the present invention is implemented, the three-dimensional network structure 100 is covered with the exterior fabric 150, but the three-dimensional network structure 100 may be configured to be removable from the exterior fabric 150. If the three-dimensional network structure 100 can be freely attached and detached according to the holding form and growth size of the infant B, a comfortable holding posture for the infant B can be pursued. In addition, only the three-dimensional network structure 100 can be washed or dried quickly, so that hygiene can be easily maintained and convenience is enhanced. In particular, when holding an infant B of a young age whose posture is unstable, the arrangement of the three-dimensional network structure 100 having the above-described hardness and repulsive force provides high protection and buffering effects for the infant B, and the body of the infant B Although the burden on the child can be reduced, a good holding posture can be easily maintained even when the three-dimensional network structure 100 is removed when the baby B that has grown and enlarged is held, and an appropriate movement of the baby B can be released. .
In addition, for example, by enclosing the three-dimensional network structure 100 with a breathable fabric made of mesh fibers in summer, air can be easily taken in and out by taking in fresh air, while in winter, breathable Thermal insulation can be obtained by coating the three-dimensional network structure 100 with a fabric without any other material.

On the other hand, the three-dimensional network structure 100 may be fixed to the exterior fabric 150 by sewing or the like. As a result, it is possible to prevent bias due to the movement of the three-dimensional network structure 100 in the exterior fabric 150, and the three-dimensional network structure 100 is maintained at an appropriate position even with a small front and back area, and effectively exhibits a buffering effect and the like. Therefore, the amount of the three-dimensional network structure 100 used can be suppressed, and the cost can be reduced.
In the case of carrying out the present invention, the main body 10 also has a structure in which the core material is appropriately disposed and the three-dimensional network structure 100 is disposed on the infant B side in order to improve the contact with the body. Also good. Also by this, since the three-dimensional network structure 100 is excellent in air permeability, dampness or the like can be reduced because moisture and heat hardly stay. Further, the body pressure is dispersed by the three-dimensional network structure 100, and the burden on the infant B can be reduced.

  TECHNICAL FIELD The present invention relates to a baby carrier (childcare band) that assists and carries an infant when it is carried or carried, and in particular, a baby having improved comfort and hygiene characteristics during holding. It is about career.

When holding an infant using a baby carrier when holding or carrying a baby, a part of the baby carrier will be applied to a part of the infant's body. Since the body temperature is high due to the immature adjustment function and the same holding posture is maintained for a long time, the user who is in close contact with the baby and the infant during use of the baby carrier has a high body temperature and is likely to sweat. Moisture such as stuffiness is also likely to occur.
In particular, in the hug that holds the infant vertically on the chest abdomen side of the user's body and the piggyback that holds the infant vertically on the user's back side, the holding form that the infant is in close contact with the user Therefore, heat and stuffiness are likely to occur due to the mutual transmission of heat between the user and the infant, and the user and the infant are uncomfortable, and the rash and diaper rash may occur when the user and the infant are used for a long time. In addition, when a so-called head hood that covers and supports the infant's rear head is used, the entire body of the infant is wrapped when the head hood is used, so that the infant is more likely to sweat. Especially for younger infants with sensitive skin and unstable posture, it is necessary to maintain a high degree of adhesion with the user in order to maintain stable and less burdensome, with less glare on the body, The effects of heat and stuffiness are significant.

  In addition, due to the increase in humidity and temperature due to stuffiness when the baby is held by the baby carrier in this way, sweat sweated from the user or infant's body due to an increase in the body temperature of the user or infant adheres to the baby carrier. By doing so, it becomes a hotbed of bacteria, and there is a risk of causing the growth of bacteria and generation of unpleasant odor in the baby carrier. In particular, the frequency of use of baby carriers has been increasing in the present age when the nuclear family is becoming more advanced, and furthermore, the development of baby carriers that can be used from the neonatal period has made it possible to use them for a long time. With regard to baby carriers that touch sensitive skin, an increasing number of users are concerned about cleanliness and hygiene.

  On the other hand, if the baby carrier pursues comfort, such as ease of pressure, shaking, shock, and stability of the infant's posture and holding, it is necessary to improve cushioning at the part applied to the infant's back and abdomen. Therefore, conventionally, as described in Patent Document 1, for example, a soft urethane foam, a polyolefin-based foam, or the like having a low resilience is used for a portion applied to the infant's back side. Also, rigid foamed urethane foam, polyolefin foam, etc. may be used as the core material to prevent the sinking of the upper body from the lower back and keep the infant's body in a stable support state. is there. Furthermore, in order to reduce the load on the user, urethane foam, polyolefin foam, or the like may be used for a shoulder belt or a waist belt worn on the user.

JP 2006-130016 A

  However, such urethane materials and polyolefin foams are basically inferior in breathability and moisture permeability, and heat and moisture that have entered the inside are difficult to escape to the outside. End up. In particular, the closed-cell foaming type has a heat storage property, which further promotes thickness and stuffiness. In addition, urethane materials and polyolefin foams may be damaged, deformed, or sag by washing, and it takes time to dry. I am worried.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a baby carrier that has cushioning properties but is resistant to stuffiness and can be held comfortably and has improved hygiene characteristics.

The baby carrier according to the first aspect of the present invention has a front fabric and a front fabric that are applied to the body of the infant on the side opposite to the user side that is applied to the infant's body and holds the infant. And a thickness of 3 mm or more and 30 mm or less, which is wrapped in an exterior fabric made of mesh-like fibers that allow air to enter and exit by movement of the infant and the user. It has a three-dimensional network structure within the range .

  Here, the holding unit is a member that is applied to the infant's body and protects the infant, and may be used depending on the purpose of the baby carrier (holding mode such as a cuddle or piggyback, age of the target infant), type, and the like. Some members are applied only to the other members, while other members may be provided to the infants and other users (parents) who hold the infants and support them. In other words, some members are applied only to the infant's non-user side, while others include both a member applied to the infant's anti-user side and a member applied to the infant's user side. In addition, the use of the three-dimensional network structure may be used only for a member applied to the infant's non-user side, or may be used only for a member applied to the infant's user side. It may be used for both a member applied to the side opposite to the user and a member applied to the user side of the infant.

The cushioning material is not limited to its purpose as long as it has a buffering function. For example, the cushioning material (elasticity) is enhanced, the contact with the body is improved, and the supporting force is enhanced. And those arranged for the purpose of improving fit and the like.
The three-dimensional network structure has a cushioning property in which a continuous linear body made of a synthetic resin meanders irregularly and is fused in the meandering state. That is, even if the space between the continuous filaments is deformed by an external force, the space is restored when the external force is released. And the space between continuous filaments is connecting, and it has air permeability by the high porosity of 70 to 98% normally. The three-dimensional network structure is wrapped in an exterior fabric to constitute the holding unit.

  The manufacturing technique of this three-dimensional network structure is well-known in the patent gazette mentioned later. This three-dimensional network structure is arranged so that the elastic change in the thickness direction in the vertical direction is large with respect to the front and back surfaces of the holding portion facing each other, and the expansion and contraction in the direction parallel to the front and back surfaces is small. The distinction between the front surface and the back surface is not particularly limited. As described above, the elasticity of the three-dimensional network structure can be arbitrarily selected, so that the number of types of synthetic resins to be selected for the regeneration process is small. The elasticity of the three-dimensional network structure changes when the infant is held, depending on the holding force or the movement of the infant and breathes.

The holding portion is configured by the three-dimensional network structure in which a portion applied to the anti-user side of the infant's body is wrapped in the outer fabric made of a front fabric and a back fabric facing the front fabric. It is what.
The part of the infant that is placed on the opposite side of the user that holds or rides the infant is applied to the infant's back when the infant is held face-to-face or carried forward.

The mesh-like fiber in which part or all of the exterior fabric in which the three-dimensional network structure is placed allows air to enter and exit may be used as long as it allows air to flow. It is not limited to using a low fabric or the fabric being knitted (net-like). For example, air can be circulated by forming multiple through holes (openings) of a predetermined shape in the fabric. It may be.
Preferably, at least a part or all of the surface applied to the infant's body is formed of mesh fibers.

  According to the baby carrier of the first aspect of the present invention, the buffer material disposed on the holding portion that holds the infant by being applied to the infant's body, the continuous linear body made of synthetic resin meanders irregularly. In addition, they are intertwined, and are fused in various places in the meandering state, and the space between the continuous filaments communicates to form a three-dimensional network structure having air permeability. According to this three-dimensional network structure, when an external force is applied, the curvature of the curved continuous filaments constituting the same changes, the space between the continuous filaments is deformed, and the external force is released, The striatum returns to its original curvature, and can express the cushioning properties (elasticity) that recover the space.

Moreover, the space between the continuous filaments constituting the three-dimensional network structure is communicated, and the air permeability is excellent.In particular, the space is also deformed by the movement of infants and users, and the flow of air is generated. Heat hardly stays and can prevent the occurrence of stuffiness.
Therefore, comfortable holding for the infant is obtained, and the burden on the infant is reduced even when used for a long time.

And, since moisture and heat hardly stay in the three-dimensional network structure in this way, it is difficult for bacteria and fungi to propagate, and further, the space between the continuous striatal bodies communicates with each other to make air permeability and moisture permeability. It is excellent in that it dries quickly, and the continuous filaments that make up the three-dimensional network structure are made of synthetic resin. They are irregularly meandered and intertwined, and are fused in a meandering state everywhere. Therefore, it has the strength to withstand repeated washing, and characteristics such as cushioning properties are unlikely to deteriorate even after repeated washing. Therefore, hygiene and cleanliness can be maintained.
In this way, a baby carrier that has cushioning properties but is resistant to stuffiness and can be held comfortably and has improved hygiene characteristics.

  In addition, for example, a shoulder belt portion that is attached to a shoulder of a user holding the infant, a waist belt portion that is attached to a waist of a user holding the infant, and a side opposite to the user of the infant as the holding portion The elasticity made of the three-dimensional network structure can be arbitrarily selected depending on the part applied to the user and the part applied to the user side of the infant as the holding portion, so that the elasticity can be selected at an appropriate place.

  In the holding part, since the three-dimensional network structure is disposed at a portion applied to the infant's body on the side opposite to the user, the three-dimensional network structure is provided at a portion that supports the infant's body over a wide area. The three-dimensional network structure relieves pressure, shaking, and shock, and does not overload the infant's posture even when used for a long time. Since heat and heat are unlikely to accumulate in the three-dimensional network structure, it is possible to effectively prevent the heat and stuffiness of the infant, and the comfort for the infant becomes higher.

  And since a part or all of the exterior fabric in which the cushioning material made of the three-dimensional network structure is placed is formed into mesh-like fibers that allow air to enter and exit, the continuous filaments constituting the three-dimensional network structure The supply of fresh air to the space between them and the discharge of air held in the space between the continuous striatum make it easier for infants and users to escape moisture and heat. The characteristics are further improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Note that, in the embodiments, the same symbols and the same reference numerals are functional portions common to those embodiments, and thus detailed description thereof is omitted here.

  First, the three-dimensional network structure 100 as a cushioning material used for the baby carrier 1 of the present embodiment will be described with reference to FIGS. 1, 2, 7 and 8.

  As shown in FIG. 1, the three-dimensional network structure 100 as a buffer material is composed of a continuous linear body 101 made of a synthetic resin that is irregularly meandering and intertwined, and is adhered to everywhere in a meandering state. Is.

  Such a three-dimensional network structure 100 is disclosed in Japanese Patent Application Laid-Open Nos. 7-173753, 7-6801, 2001-328153, 2006-97223, and International Publication No. 20111035736. JP-A-2016-528, JP-A-2013-40437, JP-A-2007-130059, etc., the production method of which is described, and the product thereof is, for example, Toyobo Co., Ltd. As "Breath Air (registered trademark)", C-CORE from C-Engine Co., Ltd., "Air Weave (registered trademark)" from Airweve, "Hytrel (registered trademark)" from Toray DuPont It is possible to use such a commercial product that is sold and publicly known.

As a precaution, an example of a method for manufacturing the three-dimensional network structure 100 will be briefly described. As shown in FIG. 2, a nozzle provided with a plurality of perforations in which a molten thermoplastic resin is formed on the bottom surface of the extruder 200. From the (die), the continuous linear body 101 is extruded vertically downward to be supplied between the endless conveyors 211 and 212 arranged in parallel in the cooling water 210 at the lower position.
At this time, the interval between the endless conveyors 211 and 212 is formed so that the gap is smaller than the outer shape of the extruded continuous resin strip 101 so that the continuous strip 101 does not leak from the endless conveyors 211 and 212. I have to. Further, the water temperature and depth of the cooling water 210 in the water tank, the extrusion temperature of the continuous filament 101, and the like are set relative to the speed and position of the endless conveyors 211 and 212.

  Thereby, when the continuous filament 101 is extruded from a plurality of nozzles formed on the bottom surface of the extrusion molding machine 200, the extrusion speed is set faster than the conveyance speed between the endless conveyors 211 and 212. When extruded from a plurality of nozzles, the shape is linear, but as the temperature drops, the pushing force becomes a force in the left-right direction to form a three-dimensional network, and the three-dimensional network changes depending on the descending speed of the endless conveyors 211 and 212. At this time, the descending speed of the endless conveyors 211 and 212 is set to be slower than the extrusion descending speed of the continuous filament 101, and the continuous filament 101 is curved and partially joined. That is, the endless conveyors 211 and 212 in which the continuous filament 101 in a molten state extruded from the extrusion molding machine 200 is rotated slower than the descent speed of the continuous filament 101 due to the buoyancy and resistance of the cooling water 210. Is curved in a three-dimensional direction due to contact with the wire, and the continuous filaments 101 are partially welded, the welded portion is cooled by the cooling water 210, and the contact portions of the continuous filaments 101 are firmly bonded. At the same time, the continuous filament 101 is fixed. In this way, the continuous filament 101 is curled (curled) and intertwined randomly, and is partially welded to form a three-dimensional network structure 100 having a specific thickness.

  In the three-dimensional network structure 100 manufactured in this way, when a synthetic resin material to be melted is extruded as a continuous filament 101, a large number of them are curved and intertwined irregularly at a high temperature, It is welded, has a three-dimensional network structure, is formed with a predetermined thickness and width, and a space is formed between the continuous filaments 101, and the space communicates with the porosity of 70% to 98%. Have And the curved continuous linear body 101 has the elasticity which returns to the original curvature, when the curvature of curvature changes with external forces and an external force is cancelled | released. For this reason, in the three-dimensional network structure 100, the curvature of the curvature of the continuous filaments 101 is changed by an external force, and the space between the continuous filaments 101 is deformed, but when the external force is released, The curvature of the strip 101 returns to the original curvature, and the elasticity is such that the space is restored. That is, even when an external force is applied, the entire three-dimensional network structure 100 is deformed, and the stress is absorbed and dispersed by the rubber elasticity of the synthetic resin, and when the stress is released, the original form is restored. It is recovered and has moderate elasticity (cushioning) and resilience. In particular, since the continuous filaments 101 are fused to each other, when an external force is applied, substantially the entire three-dimensional network structure 100 disposed on the baby carrier 1 is integrally deformed, so that pressure dispersibility is obtained. In addition, it is difficult to cause partial settling and has excellent durability. It is excellent in elasticity (cushioning property), resilience and the like due to energy conversion in which the entire three-dimensional network structure 100 is deformed integrally.

Moreover, since it is formed with the continuous linear body 101 which consists of synthetic resins, and the porosity is also 70%-98%, it is lightweight. Since it consists only of synthetic resin, it is excellent in recyclability.
Furthermore, the space between the continuous filaments 101 is larger than that of the urethane material and the polyolefin-based foam, and the space is also in communication. The porosity is 70% to 98%, more preferably 85% to 98%. By having a porosity, it is excellent in air permeability and water permeability. For this reason, it is difficult for water to accumulate, it has a quick drying property, and in particular, since the material is a synthetic resin, the elastic restoring force is also good, and it is difficult to cause breakage, deformation, and settling due to folding and washing during storage. It is excellent in durability without being damaged or deformed by sterilization such as sodium chlorite. That is, since the continuous filaments 101 are fixed to each other, the continuous filaments 101 are not moved or the entire shape is not collapsed by compression or washing, and the bulkiness or elasticity is reduced. There is little setback.
And by being excellent in air permeability and quick-drying in this way, heat and moisture are easily dissipated and the rise in temperature and humidity is prevented, so that the growth of microorganisms can be suppressed. Even if washing such as washing with water is performed, there is no fear of causing growth of microorganisms until drying, and it is hygienic because it can be kept clean by washing.

Here, as the continuous filaments 101 constituting the three-dimensional network structure 100, a thermoplastic resin is used. For example, polyethylene, polyester, EVA (ethylene vinyl acetate copolymer), polyolefin such as polypropylene, polyester such as polyethylene terephthalate, etc. And polyamides such as nylon 66, polyvinyl chloride, polystyrene, EMMA (ethylene methyl methacrylate copolymer), and PET. A mixture of a copolymer or an elastomer copolymerized on the basis of these synthetic resins may be used.
In particular, EVA resin is rich in elasticity and can have high pressure dispersibility that disperses stress concentration. In addition, since polyethylene has a high melting point, it does not change its physical properties even when sterilized with hot water, steam sterilization, etc., and is suitable for more sanitary use.
Thus, when the continuous filament 101 which comprises the solid network structure 100 is a thermoplastic resin, it is excellent also in recyclability. Further, plastic deformation due to temperature rise when using the baby carrier 1 is small, and characteristics such as cushioning properties are stably maintained.

  The fineness of the continuous filaments 101 forming the three-dimensional network structure 100 is preferably in the range of 100 to 100,000 dtex, more preferably in the range of 300 to 50000 dtex, and still more preferably in the range of 500 to 30000 dtex. . Within this range, repulsive force, tensile stress (anticompressive force), etc. are good, and sag due to stress concentration hardly occurs, and high elasticity (cushioning property) is maintained over a long period of time. For this reason, the posture of the infant B held when used as a cushioning material is also stable, and a comfortable holding feeling can be obtained.

  Moreover, the continuous linear body 101 which comprises the solid network structure 100 may be a continuous linear body which consists of not only the continuous linear body which consists of a filament of a single fineness but a filament with which the fineness differs. In addition to a single type, a plurality of types of synthetic resins may be used.

Furthermore, the continuous filament 101 may be a hollow tube (tubular shape), a solid tube, or its cross-sectional shape is not particularly limited, and may be a circular cross-section. It may be an irregular cross-section different from a circular cross-section such as a polygonal cross-sectional shape such as a triangle or a quadrangle, a Y-shaped cross-sectional shape, or a star-shaped cross-sectional shape.
Since the hollow tube (tube shape) is lighter, the solid line structure 100 having the same weight as that of the solid tube has a high density of the continuous filaments 101 and is hard. It is also possible to select the shape of the continuous striatal body 101 according to the part applied to the infant or the user's body. For example, in a region applied to an infant's buttocks, the use of the low-density three-dimensional network structure 100 made of solid continuous filaments 101 allows the infant's buttocks to be softly received with a soft touch, and the lowering of the buttocks is more enhanced. Can be stabilized. In addition, the use of the low-density three-dimensional network structure 100 at the site applied to the infant's ventral side and the user's side improves the adhesion between the infant and the user with a soft feel and improves the comfort of holding. . On the other hand, in the part applied to the infant's head and back, the infant has sufficient strength to support the infant's weight by using the high-density and hard three-dimensional network structure 100 formed of the hollow continuous filaments 101. The posture can be stabilized and the weight can be highly dispersed. Further, the waist belt portion and the shoulder belt attached to the user's waist and shoulders can be received and highly dispersed by the strength that firmly supports the weight of the infant by using the high-density three-dimensional network structure 100.

  In the present embodiment, when the three-dimensional network structure 100 is disposed on the baby carrier 1, the front and back end surfaces that have surfaces with the largest areas are located on the front side and the back side that are opposed to each other in the thickness direction. Most of the contact portions between the continuous filaments 101 are welded and flattened without exposing the continuous lengthwise ends of the stripes 101. That is, they are connected two-dimensionally. Thereby, there is no fear that the surface that hits an infant or a user gives a feeling of bumpiness or incongruity, and the exposed end portion in the length direction of the continuous filament 101 is caught by an exterior fabric 150 described later that covers the three-dimensional network structure 100. There is no damage. In addition, due to the two-dimensional connection, even when a local external force is applied to the surface, settling due to stress concentration does not easily occur and the external force is received by the surface. High pressure dispersibility to absorb and disperse water. Therefore, the burden on the body can be eased, the holding posture can be stabilized, the holding comfort and the contact with the body can be improved.

Note that such two-dimensional welding in which the end portions in the length direction of the continuous filament 101 are not exposed on the front and back end surfaces is formed by contact with the endless conveyors 211 and 212 facing each other. Of course, most of the contact portions between the continuous filaments 101 are welded and aligned in a flat shape without the continuous lengthwise ends of the continuous filaments 101 appearing on three or more outer peripheral surfaces. It may be.
In the case of carrying out the present invention, if the pair of opposed front and back end faces are such that the continuous lengthwise ends of the continuous linear body 101 do not appear, the surface layer is corrugated, continuous irregularities , Convex or concave shape, saw shape, corners may be formed in a curved surface (R) or chamfered shape.

Further, the three-dimensional network structure 100 may have a uniform overall density or may be dense.
In particular, if the front and back sides in the thickness direction are higher than the density of the inner layer, it is difficult to get loose, and a comfortable holding feeling with high pressure dispersibility can be obtained. On the other hand, for example, by increasing the density of the continuous filaments 101 on the other surface side rather than the one surface side that is applied to the infant's body, that is, the closer to the infant, the lower the density and elasticity. Softer, the farther away from the infant, the higher the density and the elasticity on the opposite side of the infant. can get.
Moreover, the characteristic and density may be changed in the thickness direction (in the form of a layer) by a combination of synthetic resins (continuous filaments 101) having different compositions and characteristics.

The density of the three-dimensional network structure 100 is adjusted by adjusting the distribution density of the continuous filaments 101 by adjusting a plurality of drilling positions and intervals of nozzles (dies) that extrude the continuous filaments 101 shown in FIG. Or by adjusting the thickness of the continuous filament 101 by adjusting the size of the plurality of perforations in the nozzle, or by adjusting the supply speed of the synthetic resin from the nozzle. . It can also be adjusted by changing the interval between the endless conveyors 211 and 212 and the rotational speed of the endless conveyors 211 and 212. Increasing the rotational speed of the endless conveyors 211 and 212 can reduce the rotational speed. It can be formed with high density by slowing down.
That is, in the three-dimensional network structure 100, even if it is the same thickness, the density is changed depending on the extrusion speed of the continuous filament 101 and the transport speed of the endless conveyors 211 and 212, thereby providing cushioning from soft to hard. it can. Further, it can be changed by the extrusion thickness of the continuous filament 101.

  Thereby, for example, as shown in FIG. 7, the density between the continuous filaments 101 is increased compared to the three-dimensional network structure 100 shown in FIG. 1, and the dense three-dimensional network structure 100 is used. Alternatively, as shown in FIG. 8, a low-density three-dimensional network structure 100 in which the density between the continuous filaments 101 is reduced as compared with the three-dimensional network structure 100 shown in FIG. 1 may be used.

Incidentally, as shown in FIG. 2, the continuous line body 101 is placed on the upper part of the water tank containing the cooling water 210 in the lower part of the extrusion molding machine 200 before and after the continuous line body 101 reaches the cooling water 210. By installing a four-sided funnel-shaped guide plate (chute) 220 that is narrowed in order to receive and guide it to the endless conveyors 211 and 212, the continuous linear body 101 extruded from the hole of the nozzle (die). A part of the guide wire 220 slides on the slope of the guide plate 220 and is guided to the endless conveyors 211 and 212. At that time, the continuous strips 101 are entangled and welded on the surface of the guide plate 220 , toward the inner layer. The surface layer having a high density can be formed by narrowing down. At the same time, the end surface of the surface layer is formed flat by sliding on the flat guide plate 220.

In the baby carrier 1 of the present embodiment, the three-dimensional network structure 100 used as a cushioning material is, for example, 25% compressive hardness (based on JIS K 6400-2, the three-dimensional network structure 100 has a diameter of 200 mm. The stress when compressed to 75% with a circular compression plate and then compressed again by 25%) is in the range of 10 N / φ200 or more and 200 N / φ200 or less, more preferably 15 N / φ200 or more and 180 N / φ200 or less. Is done. The average apparent density is in the range of 0.005 to 0.90 g / cm, more preferably 0.02 or more and 0.20 g / cm ³ or less, still more preferably 0.05 or more and 0.15 g / cm ³ or less. It is assumed to be inside. If it is within the above range, cushioning, shock absorption, and pressure dispersibility are good with moderate hardness, good contact with the body of the infant B or the user M, and the baby carrier 1 is worn for a long time. There is little stiffness and less burden. Further, the thickness of the three-dimensional network structure 100 can be selected depending on the arrangement location and the like, and is not particularly limited. However, if the thickness is within a range of 3 mm to 30 mm, more preferably 3 mm to 20 mm, a buffer function is easily exhibited. It has flexibility and flexibility so that it can be bent corresponding to the body shape of the infant B or the user M.

  Such a three-dimensional network structure 100 can be formed not only by extrusion molding but also by mold fitting, and the continuous filaments 101 are not limited to fusion bonding but are bonded by an adhesive. It may be a thing. In any case, the continuous wire body 101 made of synthetic resin is irregularly meandering and intertwined, and the three-dimensional network structure 100 formed by bonding in a meandering state is easy to manufacture and process. In addition, there are almost no pollution problems of chemicals used during production, dioxins are not generated during incineration, and recyclability is also high.

  As described above, the three-dimensional network structure 100 as a cushioning material used in the baby carrier 1 according to the present embodiment has the continuous linear body 101 made of synthetic resin irregularly meandering and intertwined, It melts everywhere in a meandering state, has a specific thickness, and communicates with the space between the continuous filaments 101 and has air permeability. Note that the directionality of ventilation and water permeability is not specified.

Next, an example of the baby carrier 1 using the three-dimensional network structure 1 having such a configuration as a cushioning material will be described mainly with reference to FIGS. 1 and 3 to 6.
Baby carrier 1 of this embodiment, by hug or piggyback infants B as a holding portion for holding the baby B Ategai the body of the baby B, the user M side of consanguinity to hug or piggyback infants B on the opposite side A main body part 10 applied to the body of the infant B and supporting the weight of the infant B; an auxiliary holding part 20 connected to the lower part of the main body part 10 and applied to the body of the infant B on the opposite side of the main body part 10; The positioning pedestal 30 is disposed between the main body 10 and the auxiliary holding unit 20. Furthermore, it is connected to the auxiliary holding part 20 and is connected to the pair of left and right shoulder belt parts 40 that are hung on the shoulder of the user M, and the lower end part of the main body part 10 and the auxiliary holding part 20 to be connected to the main body part 10 and the auxiliary holding part. The waist belt portion 50 is disposed in a direction perpendicular to the length direction of 20 and is worn around the waist of the user M.

The main body 10 applied to the body of the infant B on the opposite side of the user M holding the infant B is a face-to-face hug in which the face of the infant B and the user M face each other or the face of the infant B and the user M Like the forward facing piggyback facing in the same direction, when the infant B is held so that the abdomen of the body of the infant B faces the user M such as a parent holding the infant B, it is applied to the back side of the body of the infant B It is.
The main body portion 10 of the present embodiment is a substantially semi-elliptical head support portion 11 that is mainly applied to the head of the baby B and receives the head mainly when the baby B is held with a face-to-face hug or a forward-facing piggyback. And a back support part 12 that is applied from the head side of the infant B to the back and waist and receives mainly the back part, and a support part 13 that is applied from the back side of the infant B to the buttocks part and mainly receives the hip part. Are integrally formed.

In the present embodiment, a three-dimensional network structure 100 as a cushioning material is disposed on the main body portion 10 including the head support portion 11, the back support portion 12, and the heel support portion 13.
Specifically, as shown in FIG. 1B, the three-dimensional network structure 100 as a cushioning material is covered with an exterior fabric 150 including a front fabric 110 and a back fabric 120 and is disposed in the main body 10. The That is, the three-dimensional network structure 100 as a cushioning material is put in an exterior fabric 150 made up of a front fabric 110 and a back fabric 120 closed in a bag shape, and the main body 10 is configured.

  Thus, in the main body 10, the exterior fabric 150 made of two cloths, the front fabric 110 and the back fabric 120, wraps around the three-dimensional network structure 100 as shown in FIG. The front fabric 110 and the back fabric 120 may be formed by folding a single fabric, or may be formed by three or four. In particular, in the present embodiment, the front fabric 110 and the back fabric 120 may be folded and overlapped and sewn with two sewing threads, or a pie pin may be sewn with one of them. Alternatively, a bag shape may be formed by the front fabric 110 and the back fabric 120, and the three-dimensional network structure 100 may be inserted therein.

In the baby carrier 1 of the present embodiment, the outer fabric 150 of the front fabric 110 and the back fabric 120 constituting the main body 10 is at least the entire inner surface (infant B side) applied to the body of the infant B, or one The cloth which has air permeability is used in the position corresponding to the surface of the part, for example, the body of the infant B.
Examples of the breathable fabric include a net fabric having a mesh / mesh structure with a predetermined opening, a coarse fabric with a slightly rough texture, and an air layer having a specific thickness between the front and back net fabrics. A three-dimensional knitted fabric (double raschel) having a specific thickness formed by weaving the connecting yarn to be formed is used. By forming the exterior fabric 150 into a mesh-like fiber by using such a breathable fabric, the breathability is ensured, and the moisture absorption from the surface in contact with the infant B is increased, and moisture and heat are dissipated. can do. Hygroscopicity is also improved by using a material such as a cotton material with high water absorption.

  In particular, according to the three-dimensional knitted fabric (double raschel), against the generation of moisture and heat such as sweat of infant B and user M by the air layer formed by the connecting yarn woven between the mesh fabrics of the front and back, It has a volume that can accommodate the moisture and heat, and further, the movement of the user M and the movement of the infant B become the volume change of the air layer, and the air in the air layer is discharged and supplied. The sweat sweated from the body of M or the infant B can be quickly absorbed, and the heat of the body of the user M or the infant B can be released. Of course, because the mesh fabric and air layer on the front and back sides are excellent in air permeability and water permeability, moisture can be dried quickly. Furthermore, the air layer formed by the connecting yarn has some elasticity (cushioning), etc., and even if the infant B moves, the following change in the air layer does not cause a sense of incongruity, and the infant B's body shape fits in Good.

  Such a three-dimensional knitted fabric (double raschel) is manufactured by a woven fabric manufacturing machine such as a double raschel machine or tricot machine. The product is “Fusion (trade name)” from Asahi Kasei Co., Ltd. Since it is sold as “Aqueen (trade name)”, detailed explanation is omitted here.

When carrying out the present invention, the above-described fabric having air permeability may be used on the inner surface side of the main body 10, that is, the entire surface on the infant B side, or may be used partially. . In particular, it may be used only for the head support part 11 and the back support part 12 applied to the head and the back part where the infant B is likely to perspire. Also good. Only one of the head support part 11, the back support part 12, and the heel support part 13 may be used, only the head support part 11 and the back support part 12, only the head support part 11 and the heel support part 13, Only the abutment part 12 and the abutment part 13 may be used, or the head abutment part 11, the back abutment part 12 and the abutment part 13 may all be used. Of course, each part of the head support part 11, the back support part 12, and the padding part 13 may be sufficient.
Moreover, you may use not only the inner surface side of the main-body part 10 but the exterior cloth | dough 150 of the outer surface side of the main-body part 10, and you may use the cloth which has air permeability, the inner surface side (infant B side) and outer surface ( A structure that allows air to flow in the thickness direction on both the front and back surfaces of the baby B) is desirable. If the front and back surfaces of the main body 10 are formed of a predetermined mesh-like fiber, air passages in the thickness direction of the front and back surfaces are secured, so that the amount of ventilation increases and moisture and heat can be released more effectively. it can. Moreover, you may form in the two-layer structure which can coat | cover the non-breathable cloth with respect to the cloth which has air permeability in a specific part. In any case, in the exterior fabric 150, all or a part of the exterior fabric 150 forms an opening through which air is discharged and supplied by using a fabric having air permeability, so that a three-dimensional mesh shape inserted between the front fabric 110 and the back fabric 120 is formed. Any structure may be used as long as the air permeability of the structure 100 is utilized to maintain the air permeability.

  In addition, the fluid resistance which determines the inflow / outflow of air can be arbitrarily set by the size and number of mesh holes, that is, by selecting the mesh density. Furthermore, the mesh density may be changed according to the part of the infant B to be matched. For example, in the face of baby B and easy-to-touch parts, the fine mesh of the eyes improves the touch, and in the head support part 11 and the back support part 12 corresponding to the head and back part where the infant B tends to sweat, A rough mesh can ensure high air permeability. Further, the shape of the mesh may be determined in terms of design. The mesh structure is not necessarily required, and air circulation may be ensured by a plurality of openings.

  The exterior fabric 150 including the front fabric 110 and the back fabric 120 of the main body 10 can be formed of any fabric except for a fabric having air permeability. Further, the kind of the fabric may be changed according to the part of the infant B to be matched. For example, a soft fabric, a soft fabric with soft feeling, or a non-irritating fabric is used near the head of the infant B. A fabric with high hygroscopicity is used near the head and back of the infant B. The material of the fabric may be selected in terms of design and mechanical strength.

  And in the baby carrier 1 of this Embodiment, it consists of a synthetic resin as a buffering material inside the bag-shaped exterior fabric 150 which consists of the front fabric 110 and the back fabric 120 with which air permeability is ensured in this way. A continuous wire body 101 is irregularly meandering and entangled, and a three-dimensional network structure 100 having a specific thickness formed by welding in a meandering state is disposed.

The three-dimensional network structure 100 may be disposed throughout the main body 10 in accordance with the purpose of the baby carrier 1 (the age of the object to be retained, the retention form, etc.), the characteristics and characteristics of the commercial value, and the like. However, only a specific part may be provided. In other words, only the head support 11, the back support 12, or the heel support 13 may be disposed, or only the head support 11 and the back proof 12, the head support 11 and the heel support 13. Only the back support part 12 and the abutment part 13 may be provided, or the head support part 11, the back support part 12 and the abutment part 13 may be provided as a whole. Preferably, it is filled with an area equivalent to each part in order to prevent displacement, but may be a part of each of the head support part 11, the back support part 12, and the heel support part 13, in which case the part For example, a misalignment prevention means such as sewing on the exterior fabric 150 or forming a housing portion in the exterior fabric 150 is provided.
In addition, as described above, the three-dimensional network structure 100 can be adjusted in characteristics such as hardness, softness, elasticity, etc. according to its density, size, thickness, material of raw material, shape of the continuous filament 101, and the like. Therefore, for example, it is possible to select the three-dimensional network structure 100 having different characteristics (density, thickness, etc.) depending on the arrangement position and site, such as using a soft material for the back support portion 12 and a soft material for the support portion 13. It is.
The three-dimensional network structure 100 disposed in the main body portion 10 has a thickness of 3 mm or more and 30 mm or less, more preferably 3 mm or more and 20 mm or less. It is easily expressed and has flexibility and softness to the extent that it can be bent corresponding to the body shape of the infant B or the user M, and further, it is less bulky when being carried.

For example, by disposing the three-dimensional network structure 100 on the head support 11, the head of the infant B is supported to prevent glare, to prevent backward tilting, and to shock the head. Can be tempered. In addition, the surrounding sound can be attenuated to form a comfortable sleep environment.
In particular, the hardness at the time of 25% compression of the three-dimensional network structure 100 arranged in the head support 11 (the three-dimensional network structure 100 was compressed to 75% with a 200 mm-diameter circular compression plate and then compressed again by 25%. Stress) is preferably in the range of 10 N / φ200 or more and 180 N / φ200 or less, more preferably in the range of 10 N / φ200 or more and 130 N / φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 15 kg / φ150, more preferably 4 kg / φ150 to 10 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 10 kg / φ150 to 30 kg / φ150.
If it is within the above range, the head holder 11 that is applied to the head of the infant B firmly supports the head of the infant B without having to put a hard core material in the exterior fabric 150 separately. Since the head can be prevented from tilting and warping backward, the head of the infant B is firmly supported even when the infant B is held or when the infant B is asleep, and the head is prevented from being blurred. It is possible. Furthermore, the vibration and shock absorption by the user M walking and the like are high, and the burden on the head and neck of the infant B can be reduced.

Further, by arranging the three-dimensional network structure 100 on the backrest 12, the comfort for the infant B is improved, and the posture of the infant B and the stability of the holding are also improved.
In particular, the 25% compression hardness of the three-dimensional network structure 100 disposed in the backrest 12 is preferably in the range of 10 N / φ200 or more and 180 N / φ200 or less, more preferably 10 N / φ200 or more. , 150 N / φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 20 kg / φ150, more preferably 3 kg / φ150 to 15 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 15 kg / φ150 to 30 kg / φ150.
If it is within the above range, the back portion 12 applied to the back from the waist of the infant B without a hard core is supported firmly from the waist of the infant B to prevent falling. Thus, a stable posture of the infant B can be maintained, and even when the user M cannot reach the eyes, the infant B can be prevented from warping.

Further, by disposing the three-dimensional network structure 100 in the abutment portion 13, the buttocks of the infant B are likely to fall, the center of gravity of the infant B is stabilized, and the holding stability is improved. Moreover, the pressure applied to the buttocks of the infant B is easily dispersed, the sitting comfort is improved, and the burden on the infant B is reduced.
In particular, it is preferable that the hardness at 25% compression of the three-dimensional network structure 100 disposed in the holding portion 13 is within a range of 10 N / φ200 or more and 150 N / φ200 or less in the center portion 13A described later. Is in the range of 10 N / φ200 or more and 130 N / φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 20 kg / φ150, more preferably 3 kg / φ150 to 10 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 5 kg / φ150 to 25 kg / φ150.
If it is within the above range, the lower part of the buttocks of the infant B can be easily lowered, the center of gravity of the buttocks can be stabilized to prevent the position shift, thereby obtaining a stable sinking of the infant B and improving the holding stability. It is possible to hold in a comfortable posture with less burden on M and infant B. Moreover, even if it touches the leg of the infant B, it follows it, and the movement of the leg of the infant B is difficult to be restricted. In particular, even when holding an infant B of a young age before the neck is set, the knee of the infant B is easily bent down, so that the knee is bent at a position higher than the position of the buttocks of the infant B, and an M-shaped spread leg is formed. In a natural open leg posture, the center of gravity of the infant B is not on the leg side but on the buttocks, and the body shape of the infant B can be held with a low burden.

  Here, in the abutment portion 13 of the present embodiment, a center portion 13A that receives the center side of the buttocks of the infant B and a pair of left and right end portions 13B that are located on the left and right sides of the center portion 13A and that are near the thighs of the infant B It consists of and.

  In the baby carrier 1 according to the present embodiment, the center portion 13A and the left and right end portions 13B of the holding portion 13 are formed by draping, and the center portion 13A and the end portion 13B are located inside (center side). Is joined by a sewing line 13a that is curved in an arc shape toward the upper side, and further, the lower end portion of the abutment portion 13 is joined to the upper end portion of the main body belt portion 51 with respect to the main body belt portion 51 of the waist belt portion 50 described later. A three-dimensional accommodation space is formed by integrally connecting a straight sewing line and a sewing line (not shown) curved in an arc shape below the sewing line. This makes it difficult for the movement of the leg of the infant B to be restrained when held at a high position, which will be described later, and the position of the center of gravity of the buttocks of the infant B is easily stabilized.

  At this time, the connection between the central portion 13A and the end portion 13B in the holding portion 13 is performed by not making the three-dimensional network structure 100 inserted between the front fabric 110 and the back fabric 120 continuous, or by making the three-dimensional network structure 100 continuous. Even if the front fabric 110 and the back fabric 120 are stitched, or the three-dimensional network structure 100 itself is formed to be foldable, the central portion 13A and the end portion 13B are distinguished from each other, and the central portion An end portion 13B is formed so as to be bent toward the infant B side with respect to the surface of 13A.

  In particular, since the outer shape of the center portion 13A joined to the end portion 13B by the sewing line 13a is a shape curved toward the center side, that is, a shape narrower on the center side than the upper and lower end portions, When the three-dimensional network structure 100 is provided, the buttocks of the infant B are likely to fall, and the misalignment of the buttocks hardly occurs. Therefore, the infant B can be held in a comfortable posture with less burden, and the holding stability can be increased.

  In the case of carrying out the present invention, the thickness of the three-dimensional network structure 100 put in the outer fabric 150 of the front fabric 110 and the back fabric 120 is changed. Cushioning and flexibility of the three-dimensional network structure 100 put into the exterior fabric 150 of the front fabric 110 and the back fabric 120 by forming a recess so that the heel portion can freely fall by adding a change Also by adopting a structure that changes the sex, the drop of the buttocks of the infant B can be stabilized and the holding stability can be improved.

Furthermore, since the outer edge of the end portion 13B of the abutment portion 13 comes into contact with the thigh of the infant B, it is easy to apply a large load to the thigh of the infant B. In 13B, the arrangement of the three-dimensional network structure 100 having higher cushioning properties (elasticity) than the central portion 13A can reduce the pressure of the infant B on the thighs. For example, the three-dimensional network structure 100 disposed in the end portion 13B preferably has a 25% compression hardness within a range of 10 N / φ200 or more and 180 N / φ200 or less, more preferably 10 N / φ200 or more. , 130 N / φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 15 kg / φ150, more preferably 4 kg / φ150 to 10 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 10 kg / φ150 to 30 kg / φ150.

Moreover, in the baby carrier 1 of the present embodiment, the horizontal width in the horizontal direction is narrow at the boundary between the backrest portion 12 and the abutment portion 13 and the design is such that the abutment portion 13 widens downward from there. In particular, the butting part 13 makes it easy for the baby B to drop the buttocks, but the three-dimensional network structure 100 disposed in the back rest part 12 and the three-dimensional network structure 100 disposed in the butting part 13 are cushions. By changing characteristics such as property and hardness, for example, the hardness of the three-dimensional network structure 100 disposed in the abutment portion 13 is made softer than that of the three-dimensional network structure 100 disposed in the back support portion 12. However, by reducing the cushioning property, the posture of the infant B can be firmly supported by the back support unit 12, but the buttocks of the infant B can be easily lowered by the support unit 13.
In particular, since the three-dimensional network structure 100 has high air permeability, even if the thickness of the three-dimensional network structure 100 is increased to increase cushioning properties and hardness, it is possible to prevent stuffiness.

  As described above, the hardness, repulsive force, and cushioning properties of the three-dimensional network structure 100 are determined by its density, size, thickness, material material, shape of the continuous filament 101, and the like. Therefore, the density of the three-dimensional network structure 100, the material of the raw material, and the shape of the continuous filaments 101 may be unified, and a desired hardness may be obtained by changing only the thickness, or the three-dimensional network structure 100. May be obtained to obtain a desired hardness, repulsive force, cushioning characteristics, etc. by changing the material to a uniform thickness, and changing the material of the constituent material, the shape of the continuous filament 101, the density, and the like. .

  As described above, according to the baby carrier 1 of the present embodiment, a bag-shaped exterior fabric 150 including the front fabric 110 and the back fabric 120 that are partially or entirely formed of a fabric having air permeability to ensure air permeability. In particular, a continuous filament 101 made of a synthetic resin is irregularly meandering and entangled as a buffer material in a specific part or in the whole, and it is fused in a meandering state everywhere. A three-dimensional network structure 100 having a specific thickness formed by communicating a space between the bodies 101 is inserted to form the main body 10.

  Therefore, a buffering action and cushioning properties (elasticity) can be obtained at the portion where the three-dimensional network structure 100 is disposed. In this three-dimensional network structure 100, the space between the continuous filaments 101 constituting the three-dimensional network structure 100 is continuous. Therefore, it has air permeability, preferably with a porosity of 70% to 98%. For this reason, even if the three-dimensional network structure 100 is provided as a cushioning material, air passages are formed by the gaps between the continuous filaments 101, and the three-dimensional structure is caused by the movement of the infant B or the user M. Since the flow of air is generated by the volume change of the space of the net-like structure 100, heat and moisture are less likely to stay, and it is difficult for the infant B to be hot or stuffy.

  Since the three-dimensional network structure 100 is excellent in air permeability and hardly retains moisture and heat as described above, the continuous filament 101 is formed by irregularly meandering of the continuous filament 101 made of synthetic resin. Because most of them are loop-shaped and it is difficult for synthetic resin waste to come out, bacteria, molds, etc. are difficult to propagate compared to urethane and polyolefin foams used as conventional cushioning materials. Odor due to permeation of sweat from M and propagation of bacteria, mold, etc. hardly occurs. Furthermore, the continuous space between the continuous filaments 101 is excellent in air permeability and moisture permeability, so that it has a quick drying property, and even if it is washed, the moisture will dry quickly, and there is a risk that bacteria will grow before drying. Without washing, hygiene and cleanliness can be maintained. It can dry quickly and prevent the growth of bacteria, mold, etc., even when the baby B is drooling or adhering to water such as spitting back. Therefore, hygiene characteristics are improved. Further, the continuous filaments 101 constituting the three-dimensional network structure 100 are made of synthetic resin, and they are irregularly meandering and entangled, and are fused in a meandering state everywhere. It has the strength to withstand, and even if it is repeatedly washed, characteristics such as cushioning and cushioning properties are unlikely to deteriorate. That is, since the continuous filaments 101 are fixed to each other, the continuous filaments 101 are not moved or the entire shape is not collapsed by compression or washing, and the bulkiness or elasticity is reduced. There is little setback.

  In particular, in the present embodiment, the three-dimensional network structure 100 is covered with an exterior fabric 150 that is partially or entirely made of a fabric having air permeability, and an air flow path is formed by the air permeability of the exterior fabric 150, The heat and moisture of the infant B's body can be released. Furthermore, since fresh air is supplied to the three-dimensional network structure 100 put in the outer fabric 150 due to the air permeability of the outer fabric 150, the exhaust of moisture and high-temperature air entering the three-dimensional network structure 100 is promoted. Is done. That is, the three-dimensional network structure 100 has a volume that can store moisture and heat against the generation of moisture and heat such as sweat of the infant B due to its high porosity, but the exterior fabric 150 that covers the moisture and heat is breathable. By having fresh air, fresh air is taken in and it becomes easy to escape moisture and heat. In particular, the movement of the user M and the movement of the infant B result in a change in the volume of the space (space) between the continuous filaments 101 constituting the three-dimensional network structure 100, thereby promoting the supply and discharge of air in the space. Is done. Therefore, sweat sweated from the body of the infant B through the exterior fabric 150 can be quickly absorbed, and the heat of the user M and the body of the infant B can be released. Therefore, it is difficult for moisture and heat to accumulate in the three-dimensional network structure 100, and the heat and stuffiness of the infant B can be reduced. In addition, the body temperature of the infant B is partially and abnormally prevented even when held for a long time, and there is little tingling and stickiness, and it is a countermeasure against sweating, heat and stuffiness, and sweating.

  More preferably, both the front fabric 110 and the back fabric 120 of the exterior fabric 150, that is, the both surfaces (front and back) of the main body 10 with the surface applied to the body of the infant B and the side surface opposite thereto are breathable. When the fabric is used, the air permeability in the thickness direction of the main body 10 is increased by the air permeability of the three-dimensional network structure 100 and the fabric of the front and back surfaces, so that moisture and heat can be released more effectively. It can be refreshed and refreshed. In addition, if both the front and back surfaces (opposite surfaces) of the main body 10 are mesh-like, the fluid resistance that determines the entry and exit of air according to the body shape and operation of the user M and the infant B can be arbitrarily set.

In this way, the continuous linear body 101 made of a synthetic resin is irregularly meandering and intertwined, and the three-dimensional network structure 100 having a specific thickness formed by welding in a meandering state everywhere. For example, although the void ratio is high, the continuous filaments 101 constituting the same are made of synthetic resin, and are subjected to external force over the entire surface because they are entangled and fused in a three-dimensional manner. Compared to urethane and polyolefin-based foams, the weight is reduced as equivalent cushioning properties. Therefore, the weight and carrying burden for the user M who wears can be reduced.
In addition, the three-dimensional network structure 100 has faster recovery characteristics than conventional urethane and polyolefin-based foams that have been used as cushioning materials for the baby carrier 1, and has a fitting property and embrace that follows the body movement of the infant B. Holding property can be obtained, and holding comfort and holding stability can be improved. Therefore, even if the thickness is reduced, an appropriate cushioning property can be obtained and the bulkiness can be reduced.

  In addition, according to the three-dimensional network structure 100 in which the continuous filaments 101 are entangled three-dimensionally and have a continuous space, the concentration of weight stress can be reduced by uniformly supporting the area of the infant B. That is, the pressure receiving area is widened by the provision of the three-dimensional network structure 100, and the pressure applied to the infant B is easily dispersed. Therefore, the burden concerning the body shape of the infant B can be reduced. In particular, in the abutment portion 13 where the center of gravity of the infant B comes, the three-dimensional network structure 100 is disposed so that the pressure applied to the buttocks of the infant B is dispersed even when the infant B is held for a long time. It becomes comfortable and the burden on the buttocks of the infant B is reduced.

  In the present embodiment, even if the three-dimensional network structure 100 is disposed in the head support part 11 and the back support part 12, the front fabric 110 and the back fabric 120 at the boundary between the head support part 11 and the back support part 12. The three-dimensional network structure 100 placed between the outer fabrics 150 is not continuous, or even if the three-dimensional network structure 100 is continuous, the three-dimensional network structure 100 itself can be bent, so 11 and the backrest portion 12 are distinguished, and the headrest portion 11 can be bent with respect to the surface of the backrest portion 12. Thereby, although the back part 12 supports the back part of the infant B from the waist stably, the head part 11 is easily inclined with respect to the surface of the back part 12 according to the weight of the head of the infant B. (It is easy to bend) and the head and neck of the infant B can be protected so as not to overload the head and neck of the infant B. Further, the field of view of the infant B can be expanded by using the head support part 11 by bending the head support part 11 on the side opposite to the infant B side with respect to the surface of the back support part 12 according to the growth of the infant B.

  Furthermore, in the baby carrier 1 of the present embodiment, on the side where the infant B of the main body 10 is arranged, the surfaces of the head support 11 and the back support 12 at the boundary between the head support 11 and the back support 12. A connection portion 14 having a substantially triangular shape is provided so as to protrude from the right side, and this connection portion 14 supports the tilt of the head of the infant B in the left-right direction, prevents glare and prevents a burden on the head and neck of the infant B. Can be reduced. In particular, by forming the connecting portion 14 with a material having cushioning properties, the impact and the head and neck of the infant B can be protected. And it is also possible to arrange | position the three-dimensional network-like structure 100 as a buffer material in this connection part 14. FIG. In other words, the three-dimensional network structure 100 may be inserted between the front fabric 110 and the back fabric 120 of the exterior fabric 150 constituting the connection portion 14.

Note that the head support part 11 is provided with a pocket-like storage part having a predetermined storage capacity (not shown), and is a surface opposite to the side of the main body part 10 shown in FIG. A slide fastener 15 (a hook, a button, an adhesive cloth, etc.) for opening and closing a storage portion (not shown) on the design surface side when the user M is wearing the baby carrier 1 may be used. ), And can accommodate a head hood (not shown) having a predetermined area covering the head of the infant B , personal belongings such as a cooling agent and a towel. For example, the head hood (not shown) has one end fixed to the storage portion by sewing or the like, and the other end connected to the shoulder belt portion 40 (for example, a buckle, hook, eggplant, carabiner, D lock, quick catch, The head of the infant B is covered and supported from the back of the head, and the head of the infant B falls backwards even when the infant B is sleeping. It functions as a cover that hides breastfeeding when the baby B is fed while being held while the baby carrier 1 is worn, or the like is prevented.
In addition, it is desirable for this head hood to have air permeability, and by using the three-dimensional network structure 100 as a cushioning material, air permeability can be ensured.

  And in the baby carrier 1 of this Embodiment, the main body part 10 in which the head support part 11, the back support part 12, and the support part 13 are integrally formed in this way is the lower end part on the side of the support part 13. The waist belt portion 50 is sewn with a linear sewing line and an arc-shaped sewing line (not shown). The main body portion 10 and the waist belt portion 50 are disposed in a substantially inverted T shape as a whole, and are sewn integrally with the waist belt portion 50 by sewing the lower end of the main body portion 10 and the vicinity thereof, thereby providing a waist belt. The main body 10 can be bent in a direction perpendicular to the surface direction of the portion 50.

  The waist belt portion 50 is disposed in a direction substantially orthogonal to the length direction (vertical direction) of the main body portion 10 and the auxiliary holding portion 20 below the main body portion 10 and the auxiliary holding portion 20 described later. As a form in which the weight (the weight of the infant B) is distributed so that it can withstand the strength because it receives a lot of body weight, and it does not overload the body shape of the user M even if it is attached to the waist of the user M And a main body belt portion 51 that is integrated with the main body portion 10 and an auxiliary holding portion 20 that will be described later, and a fabric belt that has a wide belt and has a buckle with an adjuster disposed at both ends in the longitudinal direction of the main body belt portion 51. It comprises a pair of left and right length adjusters 52. The waist belt portion 50 can be fixed around the waist of the user M by the coupling engagement of the coupling insert 53 of the buckle with adjuster provided in the length adjusting unit 52 and the coupling receiver 54, and the coupling insertion By making the tool 53 and the connection receiver 54 connectable, the user 53 can freely attach and detach the waist of the user M.

  As described above, in the waist belt portion 50, the pair of left and right length adjusting portions 52 provided at both ends of the main body belt portion 51 are predetermined so that the belt length necessary for attaching the user M around the waist is determined. The connection insertion tool 53 and the connection receiver 54, each of which is made of a pair of male and female buckles with an adjuster, have an adjuster function, so that the length of the waist of the user M can be adjusted. . The adjuster may be an independent adjuster as long as the belt length can be adjusted, or may be an integrated adjuster.

  The main body belt portion 51 having a wide vertical width is formed of, for example, a material having a predetermined flexibility, flexibility, elasticity, hardness, and the like in which a cushioning material is inserted between the outer fabric 150 of the front fabric 110 and the back fabric 120. It improves the familiarity of the user M around the waist, enhances the fit so as not to bite in, makes it easier to distribute the load on the waist of the user M, and reduces the burden on the user M ing. Preferably, in the main body belt portion 51 as well, it is possible to prevent stuffiness and reduce discomfort by using the breathable fabric as described above for all or part of the exterior fabric 150 constituting the body belt portion 51. . In addition, the hygroscopicity can be improved by forming at least the inner surface that touches the waist of the user M with a water absorbent cotton fabric or the like.

  When practicing the present invention, the outer fabric 150 of the front fabric 110 and the back fabric 120 is composed of a core material made of hard urethane or polyolefin foam as a cushioning material and a soft urethane or polyolefin foam. The main body belt portion 51 can be formed using a cushion material, or the main body belt portion 51 can be formed by inserting a three-dimensional network structure 100 as a cushioning material between the outer fabric 150 of the front fabric 110 and the back fabric 120. It is also possible to configure.

In particular, in the main body belt portion 51, by providing the three-dimensional network structure 100 as a cushioning material, it is lighter and has higher air permeability than urethane and polyolefin-based foams, and can reduce moisture and the like. It becomes possible to keep it.
That is, since the three-dimensional network structure 100 is excellent in air permeability, air passages are formed, and the volume of the space in the three-dimensional network structure 100 is also changed by the movement of the user M, so that the air flow. Is promoted, moisture and heat are less likely to stay, and stuffiness can be reduced.

In particular, if the whole or part of the three-dimensional network structure 100 is covered with a breathable fabric, fresh air is taken in and moisture and heat are likely to escape. In addition, due to the high porosity of the three-dimensional network structure 100, the user M has a volume that can accommodate the moisture, such as sweat of the user M, but the movement of the user M is within the three-dimensional network structure 100. As the air layer volume changes, air in the air layer is discharged and supplied, so that sweat sweated from the body of the user M or infant B can be quickly absorbed through the breathable fabric, The moisture and heat of the body of the user M and the infant B can be released. Therefore, moisture and heat are not accumulated in the three-dimensional network structure 100, and heat and stuffiness can be reduced, and even when used for a long time, the body temperature is partially prevented from rising abnormally. It also becomes a countermeasure and can reduce discomfort due to the feeling of stuffiness around the waist of the user M.

  Of course, the front and back surfaces of the front and rear fabrics 110 and 120 constituting the main body belt portion 51, that is, the front and back surfaces of the main body belt portion 51, which is the surface applied to the body of the user M and the opposite surface, are air permeable. In the case where the cloth having the fabric is used, stuffiness is further reduced by increasing the air flow rate in the thickness direction due to the air permeability of the three-dimensional network structure 100 and the air permeability of the front and back fabrics.

  When the three-dimensional network structure 100 is used as a cushioning material for the main body belt portion 51 in this way, the main body belt portion 51 is excellent in air permeability and hardly retains moisture and heat. In comparison with the above, bacteria and molds are also difficult to propagate, and permeation of sweat from the user M and odors caused by the propagation of bacteria and molds can be prevented. Furthermore, according to the three-dimensional network structure 100, the continuous space is excellent in air permeability and water permeability and moisture permeability, so that it has a quick drying property. Hygiene and cleanliness can be maintained by washing without fear of breeding. Therefore, hygiene characteristics are improved. In addition, the continuous filaments 101 constituting the three-dimensional network structure 100 are made of synthetic resin, they are irregularly meandering and entangled, and are fused in a meandering state everywhere. Has the strength to withstand washing, and the cushioning properties are unlikely to deteriorate even after repeated washing.

Furthermore, the continuous linear body 101 is entangled three-dimensionally, and the pressure receiving area around the waist of the user M is widened by the arrangement of the three-dimensional network structure 100 having a continuous space, and the pressure applied to the user M is dispersed. It is easy to reduce the weight that the user M feels.
In particular, the three-dimensional network structure 100 disposed in the main body belt portion 51 preferably has a thickness in the range of 3 mm to 30 mm, more preferably in the range of 3 mm to 10 mm. And, if the hardness at 25% compression is in the range of 10 N / φ200 to 200 N / φ200 or less, it has appropriate elasticity, and around the waist of the user M without using a hard core material separately. Concentration of applied stress is avoided, and furthermore, due to the moderate softness, the waist belt portion 50 is prevented from floating, and the waist belt portion 50 fits along the curve around the waist according to the body shape of the user M Can be made. As a result, the load applied to the waist of the user M is well-distributed and the load on the waist of the user M is easily dispersed. The weight is not concentrated in a specific part, so the burden on the user M is reduced. It becomes difficult to feel. And even if it is easy to fit along the body shape of the waist of the user M by the solid network structure 100 of a predetermined hardness, the solid network structure 100 is hard to be stuffy because it has air permeability. In particular, it is possible to fit the back of a flat waist that does not bulge compared to the back and abdomen around the waist of the user M, so that the burden on the back of the waist can be reduced even when a piggyback is put on. .
In addition, according to the three-dimensional network structure 100, compared to a conventional cushioning material made of urethane or polyolefin foam, it is light in weight as an equivalent cushioning action, and the weight and carrying burden for the user M who wears it. Can be reduced.

In the case of carrying out the present invention, a core material made of hard urethane or polyolefin-based foam is disposed on the main body belt portion 51, and in order to improve contact with the body, a three-dimensional net-like shape is formed on the user M side. The structure 100 may be provided. Also by this, since the three-dimensional network structure 100 is excellent in air permeability, dampness or the like can be reduced because moisture and heat hardly stay. Further, the body pressure is dispersed by the three-dimensional network structure 100, and the burden on the user M can be reduced.
In addition, the connection of the waist belt portion 50 to the main body portion 10 and the auxiliary support portion 20 may be sewing, or may be a structure that can be attached and detached by an engaging means or the like.

Furthermore, in the baby carrier 1 of the present embodiment, the auxiliary holding portion 20 is sewn to the waist belt portion 50 together with the main body portion 10.
The auxiliary holding portion 20 is disposed on the infant B side of the main body portion 10, and the lower end portion thereof is integrally attached to the waist belt portion 50 together with the main body portion 10. Otherwise, the auxiliary holding portion 20 is separable from the main body portion 10. It is applied to the body of the infant B on the opposite side to the main body 10. When the infant B is held with a face-to-face hug or a forward-facing piggyback, the infant B is applied to the opposite back side, that is, the crotch side or the abdomen side.

  In the figure, the auxiliary holding part 20 is sewn to the waist belt part 50 together with the body part 10 inwardly of the connecting lateral width of the body part 10 and the waist belt part 50, and the other end side of the free end extending upward. It has a substantially trapezoidal shape that is gradually widened toward. The relationship between the auxiliary holding part 20 and the waist belt part 50 is also arranged in a substantially inverted T shape as a whole, and is integrally connected to the waist belt part 50 by sewing only the lower end of the auxiliary holding part 20. The auxiliary holding part 20 is also bendable in a direction perpendicular to the surface direction.

In the present embodiment, the three-dimensional network structure 100 as a cushioning material is also disposed in the auxiliary holding portion 20 applied to the body of the infant B on the side opposite to the main body portion 10.
Also here, the three-dimensional network structure 100 as a cushioning material is covered with an exterior fabric 150 composed of a front fabric 110 and a back fabric 120 to constitute the auxiliary support portion 20. That is, the auxiliary support portion 20 is configured by placing the three-dimensional network structure 100 as a cushioning material in an exterior fabric 150 composed of a front fabric 110 and a back fabric 120 closed in a bag shape. Thereby, the auxiliary support part 20 has predetermined softness | flexibility, flexibility, elasticity, etc., and prevents the infant B's body shape from being forced.
Further, in the auxiliary holding unit 20, a part or all of the outer fabric 150 on the infant B side or the user M side, or both of the outer fabrics 150 on the front and back sides, is used.

  As described above, in the baby carrier 1 of the present embodiment, the auxiliary holding part 20 applied to the body of the infant B on the opposite side to the main body part 10 is provided, and air permeability is provided between the infant B and the user M to be held. By disposing the three-dimensional network structure 100 covered with the cloth having the air, an air passage is formed between the infant B and the user M, and moisture and heat are easily escaped, so that an abnormal heat retention state is not reached. Also, the movement of the infant B or the user M causes a change in volume of the space (air layer) of the three-dimensional network structure 100, so that an air flow is generated, and fresh air is supplied and air with high humidity or heat is generated. Emissions are promoted. Furthermore, even when moisture such as sweat is generated, the three-dimensional network structure 100 has a volume capable of accommodating the moisture, and sweat sweated from the body of the user M or the body of the infant B is quickly absorbed. Since the space of the three-dimensional network structure 100 is continuous, the absorbed moisture is easily dissipated to the outside, and moisture and heat are not easily stored. Therefore, the heat and stuffiness due to the close contact of the user M and the infant B are remarkably reduced, and it is also a countermeasure against sweating and a sweat rash. When the infant B is held, a sticky feeling and a jerky feeling do not occur. Furthermore, even if the body shapes and movements of the infant B and the user M change, there is no sense of incongruity due to the follow-up change of the auxiliary holding unit 20. In addition, since the auxiliary holding part 20 is interposed between the user M and the infant B, it is possible to prevent wrinkles caused by the body temperature of the infant B from entering the clothing of the user M. Moreover, even if the exterior fabric 150 covering the three-dimensional network structure 100 does not have air permeability, if the density of the continuous filaments 101 is increased, air is retained and a heat insulating effect is obtained.

Since the three-dimensional network structure 100 has air permeability and is difficult to retain moisture and heat in this way, the continuous filaments 101 are formed by irregularly meandering entanglements of the continuous filaments 101 made of synthetic resin. Since most of them are loop-like and it is difficult to produce synthetic resin waste, bacteria and molds are difficult to propagate, and permeation of sweat from infant B and user M and odors caused by the propagation of bacteria and molds can be prevented. Furthermore, because it has excellent air permeability and moisture permeability due to continuous space, it has quick-drying properties, so even if you wash it, it dries quickly and there is no risk of bacteria growing before drying. Well, you can keep it clean. In addition, the continuous filaments 101 constituting the three-dimensional network structure 100 are made of synthetic resin, they are irregularly meandering and entangled, and are fused in a meandering state everywhere. Has the strength to withstand washing, and the cushioning properties are unlikely to deteriorate even after repeated washing.
In addition, a comfortable holding feeling can be obtained by appropriate cushioning properties of the three-dimensional network structure 100.

The three-dimensional network structure 100 disposed in the auxiliary holding unit 20 has a thickness of 3 mm or more and 20 mm or less, more preferably 3 mm or more and 10 mm or less. And is flexible and soft enough to be bent in accordance with the body shape of the infant B or the user M, and is less bulky when being carried.
The 25% compression hardness of the three-dimensional network structure 100 disposed in the auxiliary holding part 20 is preferably in the range of 10 N / φ200 or more and 150 N / φ200 or less, more preferably 10 N / φ200 or more, 130 N. / Φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 20 kg / φ150, more preferably 3 kg / φ150 to 10 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 5 kg / φ150 to 25 kg / φ150.
If it is in the above-mentioned range, the solid network structure 100 follows the movements of the infant B and the user M, is familiar with the body shape, and does not feel uncomfortable between the infant B and the user M, such as a sense of incongruity. A feeling can be secured.

  In addition, in the baby carrier 1 of the present embodiment, a predetermined length of cloth having a connecting plug 23 of a buckle with an adjuster at the front end via a connecting cloth 25 at both left and right ends of the auxiliary holding part 20 on the free end side. A pair of left and right connection adjusting portions 22 made of belts are attached, and the connection insertion tool 23 is located near the boundary between the backrest portion 12 and the abutment portion 13 on the left and right sides of the main body portion 10 on the infant B side (outer surface side). A buckle connection receiver 24 corresponding to the engagement is attached, and the left and right side portions on the free end side of the auxiliary holding portion 20 and the main body portion 10 by the connection engagement of the connection insertion tool 23 and the connection receiver 24. A connecting portion 21 having a predetermined length is formed to connect the left and right sides near the boundary between the backrest portion 12 and the abutment portion 13 (see FIG. 6).

  Therefore, in the baby carrier 1 of the present embodiment, the auxiliary holding portion 20 sewn to the waist belt portion 50 together with the main body portion 10 on the infant B side (inner surface side) of the main body portion 10 is connected and adjusted on both right and left sides. The distance between the main body part 10 and the auxiliary holding part 20 by being connected to the main body part 10 by the connection part 21 having a predetermined length formed by the connection engagement of the part 22 and the connection plug 23 and the connection receiver 24 ( Distance) is fixed, and the infant B is positioned in a space formed between the main body 10, the auxiliary holding part 20 and the connection part 21. Thus, the infant B is accommodated between the main body part 10, the auxiliary holding part 20, and the connection part 21, and the main body part 10 is applied to the back side of the infant B in the face-to-face hug and the forward facing piggyback. The auxiliary holding part 20 is assigned to the abdominal side, and the infant B is held by the connecting part 21 so as not to fall sideways. In particular, the leg of the infant B is passed through the annular opening formed between the left and right side edges of the main body 10 and the left and right side edges of the auxiliary holding part 20 below the connection part 21. The situation where the infant B falls from the side of the head rest 11 of the main body 10 due to the bowing of the infant B due to the restriction of the accommodation space of the infant B or the user M's forward bending posture, etc. Can be prevented. Further, even when the position of the baby B is moved with respect to the user M by switching the holding and the piggyback, the infant B can be prevented from falling and the user M can easily switch the holding and the piggyback even if not skilled. And

Furthermore, in the baby carrier 1 of the present embodiment, a pair of left and right shoulder belt portions 40 are sewn to the free end side of the auxiliary holding portion 20.
The one pair of left and right shoulder belt portions 40 are firmly attached to the left and right of the upper end portion on the free end side of the auxiliary holding portion 20 by sewing, and the other end portions are upper portions on the free end side of the auxiliary holding portion 20. It is firmly attached to the left and right side parts of the sewing machine via a connecting fabric 25 by sewing. That is, the shoulder belt portion 40 of the present embodiment is passed in the vertical direction of the auxiliary holding portion 20.

  The pair of left and right shoulder belt portions 40 are directly or indirectly connected to the auxiliary holding portion 20 and the main body portion 10 to receive much of the weight of the infant B, so that the shoulder belt portion 40 can withstand the strength of the user M. As a form in which force (the weight of the infant B) is distributed so as not to overwhelm the user M's body shape even if it is mounted around, it is integrally connected to the upper end on the free end side of the auxiliary holding part 20 and wide in width. A shoulder portion 41 and an adjustment belt portion 42 attached to the other end of the shoulder portion 41 and connected to the left and right side portions of the upper portion of the auxiliary holding portion 20 on the free end side.

  Since the shoulder portion 41 is hung on the left shoulder or the right shoulder of the user M, the shoulder portion 41 is formed of a material having predetermined flexibility, flexibility, etc. This increases the burden on the user M. For example, a cushioning material may be inserted between the outer fabric 110 and the outer fabric 150 of the back fabric 120 so that a part of the back of the user's M shoulder or neck does not cause the infant B to concentrate on the weight. . Also, the shoulder portion 41 can be used as a whole or a part of the exterior fabric 150 with a breathable fabric to prevent moisture such as stuffiness and to reduce discomfort. Furthermore, the hygroscopicity is improved also by forming at least the inner surface side of the user M that touches the shoulder of the user M with a cotton fabric having water absorption.

When practicing the present invention, the outer fabric 150 of the front fabric 110 and the back fabric 120 is composed of a core material made of hard urethane or polyolefin foam as a cushioning material and a soft urethane or polyolefin foam. The shoulder portion 41 can be formed using a cushion material, and the three-dimensional network structure 100 can be used as a cushioning material.
By disposing the three-dimensional network structure 100 as a cushioning material in the shoulder portion 41, it is lighter and more breathable than urethane and polyolefin foams, and can reduce stuffiness and maintain hygiene. It becomes possible.

  That is, since the three-dimensional network structure 100 is excellent in air permeability, air passages are formed, and the volume of the space in the three-dimensional network structure 100 is also changed by the movement of the user M, so that the air flow. Is promoted, moisture and heat are less likely to stay, and stuffiness can be reduced.

  In particular, if the whole or part of the three-dimensional network structure 100 is covered with a breathable fabric, fresh air is taken in and moisture and heat are likely to escape. In addition, due to the high porosity of the three-dimensional network structure 100, the movement of the user M has a volume that can accommodate the moisture generated by the user M such as sweat, but the movement of the user M is three-dimensional network structure. Since the air in the air layer changes in volume in 100 and the air in the air layer is discharged and supplied, the sweat sweated from the body of the user M or the infant B can be quickly absorbed through the breathable fabric, Further, the moisture and heat of the body of the user M and the infant B can be released. Therefore, moisture and heat are not accumulated in the three-dimensional network structure 100, and heat and stuffiness can be reduced, and even when used for a long time, the body temperature is partially prevented from rising abnormally. As a countermeasure, it is possible to reduce discomfort due to the feeling of stuffiness around the shoulder of the user M.

  Needless to say, the fabric having air permeability on both sides of the front fabric 110 and the back fabric 120 constituting the shoulder portion 41, that is, on the front and back surfaces of the shoulder portion 41 with the surface applied to the body of the user M and the opposite surface. Is used, the amount of air flow increases in the thickness direction due to the air permeability of the three-dimensional network structure 100 and the air permeability of the front and back fabrics, thereby further reducing moisture.

  When the three-dimensional network structure 100 is used as a cushioning material for the shoulder portion 41 in this way, the shoulder portion 41 is excellent in air permeability and hardly retains moisture and heat. Thus, bacteria and molds are also difficult to propagate, and the permeation of sweat from the user M and the odor caused by the propagation of bacteria and molds can be prevented. Furthermore, according to the three-dimensional network structure 100, the continuous space is excellent in air permeability and water permeability and moisture permeability, so that it has a quick drying property. Hygiene and cleanliness can be maintained by washing without fear of breeding. Therefore, hygiene characteristics are improved. In addition, the continuous filaments 101 constituting the three-dimensional network structure 100 are made of synthetic resin, they are irregularly meandering and entangled, and are fused in a meandering state everywhere. Has the strength to withstand washing, and the cushioning properties are unlikely to deteriorate even after repeated washing. In addition, even when the baby B is drooling or adhering to the vomit, the moisture dries quickly and can prevent the growth of bacteria and mold.

Furthermore, the continuous linear body 101 is entangled three-dimensionally, and the pressure receiving area around the shoulder and back of the user M is widened by the arrangement of the three-dimensional network structure 100 having a continuous space. It is easy to be dispersed, and the weight felt by the user M can be reduced.
In particular, the three-dimensional network structure 100 disposed in the shoulder portion 41 preferably has a thickness in the range of 3 mm to 30 mm, more preferably in the range of 3 mm to 10 mm. And if the hardness at 25% compression is in the range of 10 N / φ200 to 200 N / φ200 or less, it has appropriate elasticity and around the shoulder of the user M without using a hard core material separately. Concentration of applied stress is avoided, there is little bite, and because there is moderate softness, familiarity is easy and the load applied around the shoulder of the user M is easily dispersed, and the weight does not concentrate in a specific place The burden on the user M is reduced and it becomes difficult to feel discomfort such as pain and stiff shoulders even when worn for a long time. And even if it is easy to fit along the body shape around the shoulder of the user M by the three-dimensional network structure 100 having a predetermined hardness, the three-dimensional network structure 100 is less stuffy because it has air permeability.

In addition, according to the three-dimensional network structure 100, compared to a conventional cushioning material made of urethane or polyolefin foam, it is light in weight as an equivalent cushioning action, and the weight and carrying burden for the user M who wears it. Can be reduced.
When carrying out the present invention, a core material made of hard urethane or polyolefin-based foam is disposed on the shoulder portion 41, and a three-dimensional network structure is formed on the user M side in order to improve contact with the body. It is good also as a structure which arrange | positions the body 100. FIG. Also by this, since the three-dimensional network structure 100 is excellent in air permeability, dampness or the like can be reduced because moisture and heat hardly stay. Further, the body pressure is dispersed by the three-dimensional network structure 100, and the burden on the user M can be reduced.

In the figure, the adjustment belt portion 42 connected to one end portion of the shoulder portion 41 is a belt made of a cloth belt having a predetermined length so that a belt length necessary for mounting around the shoulder of the user M is determined. It is comprised from the part 42a, the adjuster 42b arrange | positioned by the side connected to the shoulder part 41, and the adjuster 42c arrange | positioned by the connection side to the right-and-left side part of the auxiliary | assistant holding | maintenance part 20.
Thus, the adjuster 42b is attached to one end side in the length direction of the belt portion 42a having a predetermined length, and the adjuster 42c is attached to the other end side, so that the belt length can be adjusted, and the shoulder belt portion. The length of 40 can be hung on the shoulder of the user M and adjusted to the length around the shoulder that is turned backward.

Further, a rotation type buckle connection plug 43 for connecting to the main body 10 is attached to the shoulder portions 41 of the pair of left and right shoulder belt portions 40. The connecting plug 43 is attached to the distal end of the connecting portion 14 projecting from the left and right sides near the boundary between the head support portion 11 and the back support portion 12 on the infant B side (inner surface side) of the main body portion 10. The shoulder belt portion 40 and the main body portion 10 are connected to each other by the coupling insertion tool 43 and the coupling receptacle 44 of the rotary buckle and the connection portion 14 by the coupling engagement with the coupling receptacle 44 of the rotary buckle. Unless the buckle is disengaged, the connection state of the shoulder belt portion 40 and the main body portion 10 is fixed, and the infant B accommodated between the main body portion 10 and the auxiliary holding portion 20 can be held.

  Furthermore, the shoulder belt portion 41 of the present embodiment is provided with a shoulder belt adjustment portion 46 that adjusts and holds the distance between the left and right shoulder belt portions 40. The shoulder belt adjusting portion 46 has a buckle connecting plug 46c attached to the tip of an adjustment belt portion 46a of a predetermined length attached to a shoulder hanging portion 41 that is hung on the left shoulder via a belt moving adjuster 48, and a right shoulder. A buckle connecting receiver 46d is attached to the shoulder hanging portion 41 through a belt movable adjuster 48 and a belt cloth 46b so that the connecting plug 46c and the connecting receiver 46d can be engaged with each other. Then, by adjusting the belt length by the adjustment belt portion 46a attached to the adjuster of the buckle connection plug 46c, the connection length of the shoulder belt adjustment portion 46 connecting the left and right shoulder belt portions 40 is adjusted, and the right and left The distance (distance) between the shoulder belt portions 40 can be adjusted. In the case of carrying out the present invention, the adjuster function may be provided for both the connection plug 46c and the connection receiver 46d, or only one of them may be provided, or the adjuster function may be made independent.

  As a result, in the state where the left and right shoulder belt portions 40 are hung on the shoulders, the connection insertion tool 46c of the shoulder belt adjustment portion 46 and the connection receiver 46d are connected and engaged, so that the distance between the left and right shoulder belt portions 40 is increased. It is fixed and can maintain a predetermined distance, and the left and right shoulder belt portions 40 will not come off the shoulder. In addition, by adjusting the belt length by the belt length by the adjustment belt portion 46a attached to the adjuster, a fulcrum that supports the weight of the infant B is used according to the body shape, usability, preference, how to hold the infant B, etc. It can be adjusted to a position with less burden on the person M. Therefore, even a person with a stiff shoulder can reduce the burden on the shoulder.

In addition, the shoulder belt adjustment portion 46 of the present embodiment is slid through a belt movable adjuster 48 having belt passing portions in four directions with respect to a slide belt 47 disposed along the surface of the shoulder portion 41. The shoulder belt adjusting portion 46 is movable on the surface of the shoulder portion 41.
Therefore, even when the pair of left and right shoulder belt portions 40 are hung on the shoulder of the user M, the position of the shoulder belt adjustment portion 46 is moved to connect the connection insertion tool 46c and the connection receptacle 46d of the shoulder belt adjustment portion 46. The position of engagement can be adjusted to an optimum position that is easy for the user M to operate the coupling engagement. Further, the fulcrum supporting the weight of the infant B can be adjusted to a position with less burden on the user M according to the body shape, convenience, preference, how to hold the infant B, and the like. This also reduces the burden on the shoulder for those who are stiff.
Incidentally, when the present invention is carried out, the means for adjusting or fixing the distance (distance) between the left and right shoulder belt portions 40 is limited to that by connection of the buckle or sliding of the buckle. There is nothing. Moreover, these functions may be performed by one member or may be performed by separate members.

  In the figure, the baby B is accidentally engaged with the buckle by covering the connecting plug 43 attached to the shoulder 41 of the shoulder belt 40 with the covering cover 45 attached to the shoulder 41. It prevents it from being released. Further, the buckle formed of plastic is prevented from being deteriorated by ultraviolet rays or the like. Furthermore, even if the lip of the infant B hits the shoulder portion 41 and thereby the lips of the infant B are stimulated and the shoulder belt portion 40 may be licked, by covering with the covering cover 45 attached to the shoulder portion 41, The buckle will not injure infant B's lips and tongue.

  In the baby carrier 1 of the present embodiment, the baby carrier 1 is further provided between the main body 10 and the auxiliary holding part 20 and is arranged between the main body 10 and the auxiliary holding part 20 by adjusting the length to be folded in the length direction. It has a positioning seat 30 that allows the depth of the child 10 to be freely adjusted and positions the sinking depth of the buttocks of the infant 10. Since the positioning seat portion 30 is also directly applied to the body of the infant B, it is formed of a material having predetermined flexibility and flexibility.

In the figure, the positioning pedestal portion 30 is integrally extended from the vicinity of the boundary between the backrest portion 12 and the abutment portion 13 of the main body portion 10 and gradually narrowed toward the center side, and then the other end on the opposite side. The width is gradually widened toward the part, and is formed by extending integrally from the second abutment part 31 applied to the buttocks of the infant 10 when the infant B is held with a face-to-face holding or a forward-facing piggyback. It consists of a length adjusting section 32 that can adjust the size.

  The length adjusting portion 32 integrally formed from the second abutment portion 31 is formed with a constant lateral width, and its length dimension is on the back side opposite to the opposing side of the main body portion 10 and the auxiliary holding portion 20. A pair of female sides 33a and a male side 33b of a slide-type fastener 33 as an adjustment tool for making adjustment possible, and the pair of female sides 33a and the male side 33b of the slide-type fastener 33 have a predetermined distance. Installed, apart.

  Therefore, the length between the female side 33a and the male side 33b is closed by closing the pair of the female side 33a and the male side 33b of the slide-type fastener 33 that are separated by a predetermined distance in the length adjusting unit 32. The length of the positioning pedestal 30 that is fixed in the folded state and connects between the main body 10 and the auxiliary holder 20 is shortened. On the other hand, when the engagement of the pair of female side 33a and male side 33b of the sliding fastener 33 is released, the folding is unfolded, and the positioning pedestal portion 30 has the original length and the main body portion 10 and the auxiliary holding portion 20. Connect between.

  Thus, when the infant B is disposed between the main body 10 and the auxiliary holding portion 20, a pair of female sides 33a of the sliding fastener 33 of the positioning base portion 30 that passes between the main body 10 and the auxiliary holding portion 20 is provided. In the state where the male side 33b is not engaged, the length of the positioning pedestal 30 disposed between the main body 10 and the auxiliary holding portion 20 is long. The infant B, which is housed between the main body 10 and the auxiliary holding part 20 and has the buttocks received by the positioning pedestal 30, has a deepened sinking depth. That is, the buttocks of the infant B are positioned at a low position.

  On the other hand, in the engagement state in which the pair of female sides 33a and the male side 33b of the sliding fastener 33 of the positioning base 30 passing between the main body 10 and the auxiliary holding unit 20 are closed together, a pair of female sides Since the length between 33a and the male side 33b is folded and the connection length of the positioning pedestal portion 30 connecting the main body portion 10 and the auxiliary holding portion 20 is shortened, the positioning pedestal portion 30 causes the main body portion to be shortened. 10 and the auxiliary holding part 20 is raised in depth, and the infant B, which is accommodated between the main body part 10 and the auxiliary holding part 20 and is received by the positioning pedestal 30, has a shallow sinking depth. Become. In other words, the buttocks of the infant B are positioned at a high position.

  Therefore, according to the baby carrier 1 of the present embodiment, when the infant B to be held is low in height, the slide of the positioning pedestal 30 disposed between the main body 10 and the auxiliary holder 20 is arranged. By engaging the pair of female side 33a and male side 33b of the type fastener 33 and shortening the connection length between the main body part 10 and the auxiliary holding part 20 in the positioning pedestal part 30, Since the sink is positioned at a high position, even if the infant B to be held is short, the head of the infant B does not become a low position in the positional relationship between the main body 10 and the infant B, and the head of the infant B is the head. The baby B is stably placed in a comfortable posture with less burden, without being placed in the body 11 and the body 20 and the auxiliary holder 20 so that the body of the baby B sinks.

  When the infant B to be held is tall, that is, when the infant B becomes large due to growth, the pair of female side 33a and male side 33b of the sliding fastener 33 is disengaged, By developing the connection length between the main body part 10 and the auxiliary holding part 20 to the original length in the positioning pedestal part 30, the sinking of the buttocks of the infant B is positioned at a low position. On the other hand, the head support part 11, the back support part 12, and the buttocks support part 13 of the main body part 10 are applied at appropriate positions, and the infant B is stably held in a comfortable posture with less burden.

Further, in the case where the infant B is mounted on the back side of the user M facing forward in the same direction as the user M, the length of the positioning pedestal 30 that connects between the main body 10 and the auxiliary holding unit 20 is shortened. Since the position of the buttocks of the infant B can be increased, the position of the infant B can be held at a position farther from the position of the waist of the user M, so that the spine of the user M and the spine of the infant B are repelled. As a result, the shape of the curved spine line of the infant B tends to follow the shape of the curved spine line of the user M, and the infant B easily adheres to the user M. Therefore, it is possible for the user M and the infant B to hold comfortably with a comfortable posture. In particular, the user M carrying the infant B is less likely to feel the weight of the infant B than the baby and can easily hold it. In addition, since the infant B easily comes into close contact with the user M, the infant B is unlikely to be warped backward.
Even when the buttocks of the infant B are landed on the positioning pedestal portion 30 whose original length is between the main body portion 10 and the auxiliary holding portion 20 and is placed at a low position, the auxiliary holding portion 20 and the main body portion 10 are also disposed. Are connected by the connection part 21 and the leg of the infant B is passed through the ring formed by the auxiliary holding part 20, the main body part 10 and the connection part 21, so that the infant B can be prevented from falling due to warping.

Since the positioning pedestal 30 is also applied to the body of the infant B, it is formed of a material having predetermined flexibility, flexibility, and the like. For example, the exterior fabric 150 of the front fabric 110 and the back fabric 120 is used. By forming a cushioning material between the two, the baby B can comfortably hold and sit comfortably. For example, in the second abutment portion 31 applied to the buttocks of the infant 10, the three-dimensional network structure 100 is disposed between the front fabric 110 and the back fabric 120 constituting the infant 10, so that the infant B The buttocks can be received softly, the depression of the buttocks can be facilitated, the center of gravity position of the infant B can be stabilized and the holding stability can be enhanced. And even when hold | maintaining for a long time, the fitting property to the buttocks of the infant B is high, and it becomes comfortable seating by the pressure applied to the buttocks being dispersed, and the burden on the buttocks of the infant B is reduced.

The 25% compression hardness of the three-dimensional network structure 100 disposed on the positioning pedestal 30 is preferably in the range of 10 N / φ200 or more and 150 N / φ200 or less, more preferably 10 N / φ200 or more, 130 N. / Φ200 or less. In addition, a force applied when a three-dimensional network structure 100 having a thickness of 20 mm is placed on a circular compression plate having a diameter of 150 mm, a load is applied, and 5 mm (compression ratio 25%), 10 mm (compression ratio 50%) is submerged. In the measurement of (repulsive force), the repulsive force at a compression rate of 25% (pushing amount 5 mm) is preferably in the range of 3 kg / φ150 to 20 kg / φ150, more preferably 3 kg / φ150 to 10 kg / φ150. Within range. The repulsive force at a compression rate of 50% (pushing amount 10 mm) is preferably in the range of 5 kg / φ150 to 30 kg / φ150, more preferably in the range of 5 kg / φ150 to 25 kg / φ150.
If it is within the above range, the lower part of the buttocks of the infant B can be easily lowered, the center of gravity of the buttocks can be stabilized to prevent the position shift, thereby obtaining a stable sinking of the infant B and improving the holding stability. It is possible to hold in a comfortable posture with less burden on M and infant B. Moreover, even if it touches the leg of the infant B, it follows it, and the movement of the leg of the infant B is difficult to be restricted. In particular, even when holding an infant B of a young age before the neck is set, the knee of the infant B is easily bent down, so that the knee is bent at a position higher than the position of the buttocks of the infant B, and an M-shaped spread leg is formed. In a natural open leg posture, the center of gravity of the infant B is not on the leg side but on the buttocks, and the body shape of the infant B can be held with a low burden.

In the baby carrier 1 according to the present embodiment, the portion applied to the buttocks of the body of the infant B on the side opposite to the infant B as the holding portion applied to the body of the infant B is the abutment portion 13 of the main body 10 and the positioning base portion. 30 second latching portions 31, but either the latching portion 13 or the second latching portion 31, or both the latching portion 13 and the second latching portion 31 have a three-dimensional network structure. By disposing 100, the buttocks of the infant B easily fall down, the center of gravity of the infant B is stabilized, and the holding stability is improved. Moreover, the pressure applied to the buttocks of the infant B is easily dispersed, the sitting comfort is improved, and the burden on the infant B is reduced. Of course, the sitting comfort of the infant B is improved by providing the three-dimensional network structure 100 also in the length adjusting unit 32. However, in the baby carrier 1 of the present embodiment, in the state where the length adjustment unit 32 is lengthened, it overlaps with the auxiliary holding unit 20 and is applied to the crotch side of the infant B's body. In the case where the three-dimensional network structure 100 is disposed on the positioning pedestal 30, it may be a partial arrangement of only a portion applied to the buttocks of the infant B in consideration of the bulkiness on the crotch side of the infant B, the unevenness, and the like. Of course, depending on the purpose of the baby carrier 1 and the like, when the three-dimensional network structure 100 is disposed on the positioning pedestal 30, it is possible to provide a partial arrangement of only the portion applied to the crotch side of the infant B. .

In particular, since the three-dimensional network structure 100 has high air permeability, even if it is in close contact with the buttocks of the infant B, it is difficult to get stuffy, and diaper rashes are hardly caused. In addition, as described above, hygienic characteristics are also improved.
And in this positioning base part 30, since it will be applied directly to the infant B, moisture such as stuffiness is prevented by using a fabric having air permeability as a whole or a part of the exterior fabric. And discomfort can be reduced. Also, the hygroscopicity is improved by forming at least the upper surface side (surface side) in contact with the infant B with a cotton fabric having water absorption.

Note that the length adjustment unit 32 that can be folded is also flexible and flexible enough to be folded, and elastic and buffered so that the infant B does not feel uncomfortable or uncomfortable. Alternatively, the three-dimensional network structure 100 may be disposed with a small thickness.
The positioning pedestal portion 30 is formed of a material with less stretchability that does not stretch and elastically deform when the external force that receives the weight of the infant 10 is applied and the elastic force acts strongly in the direction of gravity.

As described above, the baby carrier 1 according to the present embodiment includes the main body 10, the auxiliary holding unit 20, and the positioning as a holding unit that holds the baby B by holding or holding the baby B by the body of the baby B. In the baby carrier 1 having the pedestal portion 30, the main body portion 10, the auxiliary holding portion 20, and the positioning pedestal portion 30 as a holding portion for holding the infant B are configured by the exterior fabric 150 and the cushioning material wrapped in the exterior fabric 150. In addition, the continuous linear body 101 made of a synthetic resin is irregularly meandering and entangled with the buffer material, and is melted everywhere in a meandering state, and the space between the continuous linear bodies 101 communicates and has air permeability. The three-dimensional network structure 100 is used.

That is, the baby carrier 1 according to the present embodiment is disposed and held in the main body 10, the auxiliary holding portion 20, and the positioning pedestal portion 30 as holding portions that are applied to the body of the infant B and hold the infant B. The cushioning material placed in the exterior fabric 150 made up of one front fabric 110 and the other back fabric 120 opposite to the front fabric constituting the main body portion 10, the auxiliary holding portion 20, and the positioning pedestal portion 30 as synthetic members is a synthetic resin. The continuous filaments 101 are irregularly meandered and intertwined, and are fused in a meandering state, and the space between the continuous filaments 101 communicates with each other so as to provide a three-dimensional network having air permeability. The structure 100 is formed.

Therefore, according to the baby carrier 1 according to the present embodiment, when an external force is applied due to the arrangement of the three-dimensional network structure 100, the curvature of curvature of the curved continuous filament 101 constituting the same changes, When the space between the continuous filaments 101 is deformed and the external force is released, the continuous filaments 101 return to the original curvature, and the cushioning property (elasticity) for restoring the space is excellent. In particular, since the continuous filaments 101 are fused together, the pressure receiving area is wide, and when an external force is applied, the entire three-dimensional network structure 100 is deformed, and the user M and infants with a small sinking depth. Supports the body of B, disperses the pressure applied to the body evenly, and has a cushioning property with little bottom feeling even if the thickness is thin.
Moreover, the space between the continuous filaments 101 constituting the three-dimensional network structure 100 communicates with each other, and the air permeability is excellent. Therefore, moisture and heat hardly stay, heat can be reduced, and the occurrence of stuffiness can be prevented.
Therefore, a comfortable holding feeling for the infant B is obtained, and the burden on the infant B is reduced even when used for a long time.

  And since moisture and heat do not easily stay in the three-dimensional network structure 100 in this way, it is difficult for bacteria, fungi, etc. to propagate, and furthermore, the space between the continuous striatal bodies 101 communicates with each other so that air permeability and water permeability can be obtained. And the moisture content dries quickly, and the continuous filaments 101 constituting the three-dimensional network structure 100 are made of a synthetic resin. They are irregularly meandered and intertwined, and in a meandering state everywhere. Since it is fused to each other, it has strength to withstand repeated washing, and characteristics such as cushioning properties are unlikely to deteriorate even after repeated washing. Therefore, hygiene and cleanliness can be maintained.

  In particular, when a part or all of the exterior fabric 150 including the cushioning material made of the three-dimensional network structure 100 is formed into mesh-like fibers that allow air to enter and exit, the continuous filaments constituting the three-dimensional network structure 100 are formed. By supplying fresh air to the space between the bodies 101 and discharging the air held in the space between the continuous filaments 101, moisture and heat from the infant B and the user M can easily escape. A partial increase in body temperature can be prevented, and stuffiness can be further prevented. In addition, hygiene characteristics are improved. Furthermore, by making the fabric into a mesh structure having a mesh structure or a plurality of ventilation holes, flexibility and stretchability are also increased, and the fit and familiarity with the body shape and movement of the infant B and the user M are improved. In addition, since the weight is reduced, the burden on the user M is also reduced.

In this way, according to the baby carrier 1 according to the present embodiment, it is cushioned, but it is difficult to stuffy and can be held comfortably, and even if the baby B is held for a long time, the baby B can be less tired. In addition, hygienic characteristics are improved.
Further, even if the head hood is used, moisture and heat are difficult to be stored, which is advantageous for laying on the bed, and the infant B who is sleeping is prevented from sweating excessively, and a comfortable sleeping environment can be created.
In addition, since the three-dimensional network structure 100 has high air permeability and moisture and heat are not easily trapped in the cushioning material, the heat is reduced and the stuffiness is reduced. Thus, affected areas such as sweat rash and atopic dermatitis can be kept hygienically, deterioration can be prevented, and their onset can be prevented.
In addition, because the three-dimensional network structure 100 communicates with the gap, moisture can not be accumulated even when sprayed with deodorizing alcohol or a disinfecting spray, so that cleanliness and hygiene can be maintained.

And in the holding | maintenance part applied to the body of the infant B and holding the infant B, the three-dimensional network structure 100 is arrange | positioned in the main-body part 10 applied to the body of the infant B on the opposite side to the user M side. Thus, compression, shaking and impact are alleviated by the three-dimensional network structure 100 which is supported on a large area with respect to the body of the infant B, and the posture of the infant B is not burdened even when used for a long time. However, it is difficult for moisture and heat such as sweat from the infant B to accumulate in the three-dimensional network structure 100, so that the heat and stuffiness of the infant B can be effectively prevented, and the comfort for the infant B becomes higher. .

Here, in the main body 10 as a holding unit that holds the infant B by being applied to the body of the infant B, the body B is applied to the head of the body of the infant B when holding the infant B with a face-to-face holding or a forward facing piggyback. If the hardness and repulsive force of the three-dimensional network structure 100 disposed on the head support 11 as a part is too small, the neck and head of the infant B may sway, or the head may hang backwards during sleep, etc. Therefore, a separate core material is required. On the other hand, if it is too large, the hit on the body becomes stronger.
According to the experimental study by the present inventors, the hardness at the time of 25% compression (stress when the three-dimensional network structure 100 is compressed to 75% with a 200 mm diameter circular compression plate and then compressed again by 25%). 10 N / φ200 or more and 180 N / φ200 or less, more preferably 10 N / φ200 or more and 130 N / φ200 or less, and a three-dimensional network structure 100 having a thickness of 20 mm is formed into a circular compression plate having a diameter of 150 mm. The load is applied to 5 mm (compression rate 25%), and the applied force (repulsive force) when submerged 10 mm (compression rate 50%). The compression rate 25% (push-in amount 5 mm) The repulsive force at the time is in the range of 3 kg / φ150 or more and 15 kg / φ150 or less, more preferably in the range of 4 kg / φ150 or more and 10 kg / φ150 or less, and the compression rate is 50% (indentation amount 1 0 mm), the repulsive force is preferably in the range of 5 kg / φ150 or more and 30 kg / φ150 or less, and more preferably in the range of 10 kg / φ150 or more and 30 kg / φ150 or less. The head and neck of the infant B can be supported and the impact can be reduced.

That is, the three-dimensional network structure 100 disposed at the portion applied to the head of the infant B in the holding portion that holds the infant B by being applied to the body of the infant B is 10N / φ200 or more and 180N / φ200 or less. The hardness at 25% compression within the range is preferable, and the hardness at 25% compression within the range of 10 N / φ200 to 130 N / φ200 is more preferable.
25% of the three-dimensional network structure 100 disposed at the portion of the holding portion that is applied to the head of the body of the infant B when facing the user M with the ventral side of the infant B facing the user M or facing forward. If the hardness at the time of compression is in the range of 10 N / φ200 or more and 180 N / φ200 or less, the head and neck of the infant B can be supported and impact can be reduced without providing a separate hard core.

In addition, the three-dimensional network structure 100 disposed at a portion applied to the head of the infant B in the holding portion that holds the infant B by being applied to the body of the infant B is 150 mm in thickness of the three-dimensional network structure 100 having a thickness of 20 mm. When the load is applied to a circular compression plate with a diameter of 5 mm (compression rate 25%) and the applied force (repulsive force) is submerged, the repulsive force during compression is 25% (push-in amount 5 mm).

That is, when carrying out the present invention, the holding part for holding the infant M may be only the main body part 10 applied to the body of the infant B on the side opposite to the user M holding the infant B, or the infant B The body 10 applied to the body of the infant B on the side opposite to the user M side holding the child and the auxiliary holding part 20 applied to the body of the infant B on the side opposite to the body 10 side, that is, the user M side. May have.
When the holding part for holding the infant B is constituted only by the main body part 10, the three-dimensional network structure 100 as a cushioning material is disposed in the main body part 10, but the holding for holding the infant B When the part is constituted by the main body part 10 and the auxiliary holding part 20, the three-dimensional network structure 100 may be disposed on both the main body part 10 and the auxiliary holding part 20, or the arrangement of the three-dimensional network structure 100 may be provided. Only one of the main body part 10 and the auxiliary holding part 20 may be provided.

  Further, when the present invention is implemented, the waist belt portion 50 is not necessarily required and can be omitted, and an opening through which the leg of the infant B is put out in a holding form in which the infant B does not fall is formed. However, it is also possible to support the weight of the infant B with only the left and right shoulder belt portions 40 and hold or carry the infant B.

  In the figure, the shoulder belt portion 40 is connected to the auxiliary holding portion 20. However, when the present invention is carried out, the shoulder belt portion 40 is provided only on the main body portion 10 as long as the infant B can be held. May be connected, or the shoulder belt portion 40 may be connected to the main body portion 10 and the auxiliary holding portion 20. In any case, it may be configured to be connected to a position that does not interfere with the body of the infant B and to form a ring through which the shoulder of the user M is passed.

Moreover, in the said embodiment, although it was description about the baby carrier 1 of the form which hold | maintains the infant B in the vertical holding, when implementing this invention, it has the holding form of the side holding the baby B laid down. Berry carrier 1 may be used. It should be noted that the shoulder belt portion 40 is usually worn by sashing on the side. Moreover, the structure which enables the holding form of both vertical holding and horizontal holding may be sufficient.
In particular, when the three-dimensional network structure 100 is disposed in the holding portion that applies the back side of the infant B when holding it sideways, the back side of the body of the infant B laid sideways is supported from multiple directions, The pressure dispersion effect is high, vibrations and the like can be absorbed, and the burden on the infant B can be reduced even when held for a long time.

Furthermore, when the present invention is implemented, the three-dimensional network structure 100 is covered with the exterior fabric 150, but the three-dimensional network structure 100 may be configured to be removable from the exterior fabric 150. If the three-dimensional network structure 100 can be freely attached and detached according to the holding form and growth size of the infant B, a comfortable holding posture for the infant B can be pursued. In addition, only the three-dimensional network structure 100 can be washed or dried quickly, so that hygiene can be easily maintained and convenience is enhanced. In particular, when holding an infant B of a young age whose posture is unstable, the arrangement of the three-dimensional network structure 100 having the above-described hardness and repulsive force provides high protection and buffering effects for the infant B, and the body of the infant B Although the burden on the child can be reduced, a good holding posture can be easily maintained even when the three-dimensional network structure 100 is removed when the baby B that has grown and enlarged is held, and an appropriate movement of the baby B can be released. .
In addition, for example, by enclosing the three-dimensional network structure 100 with a breathable fabric made of mesh fibers in summer, air can be easily taken in and out by taking in fresh air, while in winter, breathable Thermal insulation can be obtained by coating the three-dimensional network structure 100 with a fabric without any other material.

On the other hand, the three-dimensional network structure 100 may be fixed to the exterior fabric 150 by sewing or the like. As a result, it is possible to prevent bias due to the movement of the three-dimensional network structure 100 in the exterior fabric 150, and the three-dimensional network structure 100 is maintained at an appropriate position even with a small front and back area, and effectively exhibits a buffering effect and the like. Therefore, the amount of the three-dimensional network structure 100 used can be suppressed, and the cost can be reduced.
In the case of carrying out the present invention, the main body 10 also has a structure in which the core material is appropriately disposed and the three-dimensional network structure 100 is disposed on the infant B side in order to improve the contact with the body. Also good. Also by this, since the three-dimensional network structure 100 is excellent in air permeability, dampness or the like can be reduced because moisture and heat hardly stay. Further, the body pressure is dispersed by the three-dimensional network structure 100, and the burden on the infant B can be reduced.
