Examples include sites and welding factories. Here, the use in a medical institution will be described as an example.

The wearer can wear the cooling clothes 2 so as to be located on the outermost side, but can also wear the cooling clothes 2 in the outer garment. Outerwear means the outermost garment worn by the wearer. The outer garment may be a one-piece type in which an upper garment covering the upper body and a lower garment covering the lower body are connected, or a two-piece type in which the upper garment and the lower garment are separated. Examples of the outer garment include work clothes, protective clothing, chemical protective clothing, dust-proof clothing, fire-resistant clothing, bee-resistant clothing, racing driver clothing, jumpers (blousons), uniforms, and feathers. Since the cooling clothes 2 as the inner garment are non-breathable, the outer garment may be non-breathable or may have breathability. The cooling garment 2 according to the present embodiment is worn in the chemical protective garment as the outer garment, but the outer garment is omitted in the drawings.

(2) Cooling clothes (middle clothes)
The cooling clothes 2 are clothes worn by the wearer, and cool the wearer's body by the air supplied from the blower 3. The cooling clothes 2 are worn in the outer garment as described above, but may be used without wearing the outer garment.

The cooling clothes 2 are non-breathable. As used herein, the term "non-breathable" means a property that does not allow air to pass through, and includes, for example, not only a property that does not allow air to pass through completely, but also a property that allows air to pass through slightly. For example, ^{a fabric having a breathability of 0 cm 3} / cm ² · s or more and 20 cm ³ / cm ² · s or less is in the category of “non-breathable” fabric. As the non-breathable fabric, it is preferable that ^{the air permeability is 0 cm 3} / cm ² · s or more and 10 cm ³ / cm ^{2 · s.} The "air permeability" referred to here is measured by a method based on the JIS L 1096 A method Frazier method.

The outer material of the cooling clothes 2 is made of a non-breathable fabric made of knitted fabric. A knitted fabric is a fabric knitted with threads and has elasticity. The outer material is, for example, coated or laminated with a resin on a knitted material, a resin film is laminated on a knitted material, or a calendar process is performed by pressing a resin film on a knitted material. This makes it a non-breathable fabric.

As the fibers constituting the knitted fabric, chemical fibers, natural fibers, or synthetic fibers thereof are used. The chemical fiber is not particularly limited, and examples thereof include urethane fiber, polyester fiber, nylon fiber, polypropylene fiber, and polylactic acid fiber. The natural fiber is not particularly limited, and examples thereof include cotton, linen, silk, rayon, and wool. The knitted fabric according to the present embodiment is composed of a knitted fabric made of nylon fibers (100%) from the viewpoint of improving elasticity.

The knitting method is not particularly limited. For example, flat knit (tenjiku), rubber (milling), pearl, tuck, transfer, single-sided, double-sided, double-sided, swing, etc. Examples thereof include pererin knitting, lace knitting, floating knitting, pile knitting, and splicing yarn knitting. Among these, rubber knitting (milling knitting) is preferable from the viewpoint of improving elasticity.

The outer fabric of the cooling garment 2 according to the present embodiment is formed by laminating a polyurethane film on a material made of a knitted fabric made of nylon fibers. Specifically, for example, New Raid (registered trademark) is preferably used. In short, the cooling clothes 2 are non-breathable and have elasticity. The polyurethane film may be laminated on the outer side or the inner side of the knitted material, and is not particularly limited. However, by laminating the polyurethane film on the inner side of the knitted material, the cooling appearance is good. It is easy to realize clothes 2.

As used herein, "having elasticity" means having an elongation rate of 40% or more in the vertical direction and 60% or more in the horizontal direction. From the viewpoint of improving the elasticity of the cooling clothes 2, the elongation rate is preferably 80% or more in the vertical direction and 100% or more in the horizontal direction, and more preferably 90% or more in the vertical direction and horizontal. : 120% or more, more preferably vertical: 100% or more, and horizontal: 140% or more. The elongation rate of the outer material of the cooling clothes 2 according to the present embodiment is vertical: 100% and horizontal: 143%. The "elongation rate" referred to here is measured by a method based on the JIS L 1096 strip method. In addition, "vertical" and "horizontal" here refer to vertical and horizontal in the state of the dough.

The cooling clothes 2 are set so that when air is supplied from the blower device 3, a gap having a predetermined size or less is formed between the cooling clothes 2 and the wearer's body. The "space having a predetermined size or less" means that the size of the space between the surface of the body and the inner surface of the cooling clothes 2 is 10 mm or less, preferably 5 mm or less, and more preferably 3 mm or less. By limiting the gap formed between the wearer's body and the wearer's body to a dimension equal to or less than a predetermined size, the wearer's body temperature can be effectively lowered as described in "(1) Test 1" in the examples described later. ..

The inner surface of the cooling garment 2 is set to a size that forms a gap of a predetermined size or less with respect to the wearer's body. For example, the cooling garment 2 has a size in which a gap having a predetermined size is formed when the inside of the cooling garment 2 becomes positive pressure with respect to the virtual surface of the body of the wearer's reference size assuming that the cooling garment 2 is worn. It is configured according to. Therefore, it is preferable that a plurality of types of cooling clothes 2 are formed according to the assumed wearer's reference size.

By the way, if the cooling clothes 2 of the above size are made of a non-stretchable fabric, it is difficult for even a wearer who conforms to the standard size to wear them. However, as described above, the cooling garment 2 according to the present embodiment is made of a non-breathable and stretchable fabric, and therefore adopts a size capable of effectively lowering the wearer's body temperature. However, it can be easily worn by the wearer.

The lining of the cooling clothes 2 is made of a fabric that does not hinder the elasticity of the outer material. The fabric that makes up the lining is breathable. The lining is made of, for example, a mesh fabric made of synthetic fibers. Examples of the "synthetic fiber" here include polyester, nylon, polyurethane and the like.

Cooling garment 2 includes, as shown in FIGS. 2 and 3, the predecessor around 22, and the rear body around 21, a pair of sleeves 23, a neck portion 26, a. Predecessor around 22, and the rear body around 1 is composed of a front fabric and lining above. Further, the pair of sleeves 23 are made of the above-mentioned outer material.

Rear only around 21 covers the rear surface of the upper body of the wearer. The rear body around 21, as shown in FIG. 3, the supply port 211 of the blower 3 is attached is formed. Supply port 211, passes through the rear only around 21. The air supplied from the blower 3 passes through the supply port 211 and enters the inside of the cooling clothes 2.

Before only around 22 covers the front of the upper body of the wearer. Predecessor around 22, as shown in FIG. 2, has a connection portion 221 formed at the center in the lateral direction. Connecting portion 221, or to separate themselves around 22 in the lateral direction before, or can be connected. Examples of the connecting portion 221 include a button, a wire fastener, a surface fastener, and the like, but the wire fastener is preferable from the viewpoint of ensuring the airtightness in the cooling clothes 2. In this embodiment, a line fastener is used.

The predecessor around 22, front-side exhaust port 222 for discharging the air inside the cooling garment 2 is formed. Front-side exhaust port 222, the front (in this case two) more penetrating only around 22 is composed of a through-hole 24 of the. Each through-hole 24, the front are constituted by eyelets which are attached to the body around 22, for example, a slit may be constituted by a slot hole or the like. Further, the front exhaust port 222 does not have to be the through hole 24, and may be formed of, for example, a mesh-processed portion, a breathable fabric, or the like.

The plurality of through holes 24 are formed in a range above the center of the cooling clothing 2 and below the neck circumference 26 in the vertical direction, in other words, formed at a position facing the wearer's chest. Has been done. The through hole 24 is located above the supply port 211 in the vertical direction. More particularly, the through-hole 24, in the predecessor around 22, the upper side in than the center in the vertical direction of the cooling garment 2, and the central portion in the lateral direction (the region of the middle when the left-right direction 3 equal portions) It is formed within the range of. The term "wearer's chest" as used herein means a portion between the wearer's clavicle and abdomen, and includes, for example, an epigastrium.

The front exhaust port 222 is preferably located below the position of the wearer's clavicle. If the front exhaust port 222 is located above the clavicle, the air discharged from the front exhaust port 222 is more likely to directly hit the wearer's face.

The sleeves 23 cover the wearer's shoulders to wrists, i.e., the wearer's arms. A cuff portion 231 is formed at the tip of the sleeve 23. The cuff portion 231 is configured to be expandable and contractible so as to be able to contract in the circumferential direction of the cuffs. Therefore, the cuff portion 231 is in close contact with the wearer's wrist and prevents the air inside the cooling clothes 2 from coming out from the cuffs. The cuffs 231 are configured to be stretchable by sewing rubber. For example, rib knitting, a structure of tightening with a string, and a hook-and-loop fastener or a button on which one end and the other end in the circumferential direction of the cuffs are overlapped. It is also possible to adopt a structure or the like that is fastened by.

Here, the term "adhesion" as used herein means a mode in which the wearer's skin or clothing is pressed tightly. Therefore, not only when the cooling clothes 2 are directly attached to the wrist, but also when, for example, when the cooling clothes 2 are worn outside the wearer's upper garment, the cuffs 231 press the sleeves 23 of the upper garment. It is included in "adhering to".

The sleeve 23 is formed with an arm-side exhaust port 232 at a portion between the cuff portion 231 and the shoulder portion. The arm-side exhaust port 232 is a port for letting out the air inside the cooling clothes 2. As shown in FIG. 4B, the arm-side exhaust port 232 according to the present embodiment is composed of a plurality of (five here) through holes 24 penetrating the sleeve 23. Like the front exhaust port 222, each through hole 24 is formed of eyelets, but may be formed of, for example, a slit, a slot hole, or the like. Further, the arm-side exhaust port 232 does not have to be the through hole 24, and may be formed of, for example, a mesh-processed portion, a breathable fabric, or the like.

As shown in FIG. 4A, each through hole 24 is formed at a portion located on the shoulder side by a certain dimension or more from the cuff in the longitudinal direction of the sleeve 23. Therefore, even if gloves are used, it is possible to prevent the air from the cooling clothes 2 from coming out from the cuffs and entering the gloves. The term "above a certain size" as used herein means a dimension such that the through hole 24 is not covered with gloves when the cuff portion 231 of the sleeve 23 is covered with gloves. In this embodiment, the constant dimension L1 is, for example, 15 cm, preferably 20 cm. If the sleeve 23 is located closer to the shoulder than the center in the longitudinal direction, the cooling effect of the wearer's arm is reduced, so that the sleeve 23 is preferably located closer to the cuff than the center in the longitudinal direction.

The diameter of each of the through holes 24 constituting the front exhaust port 222 and the arm side exhaust port 232 is preferably 20 mm or less, more preferably 15 mm or less. If the diameter of the through hole 24 exceeds 20 mm, there is a concern that the strength of the outer material may decrease or the pressure inside the clothes may decrease. The through hole 24 according to the present embodiment is formed of eyelets having an inner diameter of 5 mm, and stretch-inhibiting cloth is laminated and reinforced at the portion to which the eyelets are attached. The stretch-suppressing cloth is composed of a cloth having a stretch rate smaller than that of the outer material, and is composed of, for example, a woven cloth, a non-woven fabric, or the like.

Here, the cooling clothing 2 according to the present embodiment includes a front exhaust port 222 and a pair of arm side exhaust ports 232 as described above, but the opening area of each arm side exhaust port 232 is the front side exhaust. It is formed larger than the opening area of the mouth 222. Here, the "opening area of the arm side exhaust port 232" and the "opening area of the front exhaust port 222" mean the total opening area of the through holes 24.

The opening area of each arm-side exhaust port 232 is preferably set to four times or more the opening area of the front-side exhaust port 222. In the cooling clothing 2 according to the present embodiment, each arm side exhaust port 232 is composed of five through holes 24, and the front side exhaust port 222 is composed of two through holes 24. Therefore, the opening area of each arm-side exhaust port 232 is 4.5 times the opening area of the front-side exhaust port 222.

When the opening area of each arm-side exhaust port 232 is made larger than the opening area of the front-side exhaust port 222, the body temperature of the wearer is effectively lowered as described in "(2) Test 2" in the examples described later. be able to. In particular, if the opening area of each arm-side exhaust port 232 is set to four times or more the opening area of the front-side exhaust port 222, the wearer's body temperature can be lowered more effectively.

Cooling garment 2 of the skirt 25 (i.e., the lower end portion of the front body around 22 and the rear body around 21) is telescopically adapted to contract in the circumferential direction of the skirt of the opening. Therefore, the hem portion 25 can be brought into close contact with the wearer's torso. For the hem portion 25, for example, a structure of rib knitting, rubber, a structure of tightening with a string, a structure of overlapping one end and the other end of the cuffs in the circumferential direction and fastening with a hook-and-loop fastener or a button can be adopted. In the present embodiment, the hem portion 25 can be brought into close contact with the body portion by tightening the string.

The neck circumference 26 is a portion that comes into close contact with the wearer's neck. The neck circumference 26 is in close contact with the wearer's neck and prevents the air supplied from the supply port 211 from going out. The neck circumference portion 26 includes a rib collar 261 and a band body 262 that presses the rib collar 261 from the outside.

The rib collar 261 is a portion facing the wearer's neck. The rib collar 261 is configured to be stretchable so that it can contract in the circumferential direction around the neck. The rib collar 261 is made of rib knitting. The band body 262 is composed of a shrinkable rubber band, and the tip end portion of the band body 262 can be fixed at an arbitrary position in the longitudinal direction of the band body 262. The fixing of the rubber band is realized by, for example, a hook-and-loop fastener, and the tightening strength can be adjusted steplessly.

The tightening strength of the band 262 can be adjusted steplessly by the hook-and-loop fastener. For example, a plurality of buttons are fixed at regular intervals in the circumferential direction around the neck, and the band 262 is attached to the plurality of buttons. By fixing to one of them, the tightening strength may be adjusted in stages. Further, the band 262 does not necessarily have to be stretchable.

The neck circumference 26 can prevent the air from coming out from the neck circumference even if the air inside the cooling clothes 2 becomes positive pressure. Therefore, for example, when the chemical protective clothing is used as the outer garment, it is possible to prevent the air discharged from the cooling clothing 2 from flowing into the inside of the mask covering the head.

The cooling clothes 2 include a cushion material 27. The cushion material 27 is arranged between the outer material and the lining and is fixed to the outer material. Fixing of the cushion material 27 and the outer material is realized by, for example, adhesion, suturing, crimping, welding, or the like.

The cushion material 27 has breathability. Further, the cushion material 27 has elasticity. The cushion material 27 is attached to the portion of the cooling clothing 2 facing the back, shoulders, and chest of the wearer. When an external force is applied to the cooling clothes 2 (including the case where a force is applied to the cooling clothes 2 from the outer garment to which the external force is applied), the cushion material 27 receives the external force and also receives the external force of the wearer's body. It is possible to secure a flow path for air flowing along the surface. Examples of the external force applied to the cooling clothes 2 include an external force when a harness or suspenders are attached, an external force when carrying luggage or equipment while wearing the cooling clothes 2, and the like. That is, according to the cooling clothes 2 according to the present embodiment, as shown in FIG. 5, even if the gap between the body and the cooling clothes 2 is closed by an external force, the cushion material 27 secures the air flow path. be able to.

The cushion material 27 is not particularly limited as long as it has elasticity and breathability. For example, a three-dimensional network structure 271 of a thermoplastic resin, a synthetic fiber filament such as ester, nylon, polypropylene, or polyethylene can be used. Examples include the double Russell knitted fabric used. Among them, the three-dimensional network structure 271 is preferable in consideration of the cushioning property when an external force is applied, the wearing feeling of the cooling clothes 2, and the workability.

Here, the three-dimensional network structure 271 is as shown in FIG. 6, in which a large number of lines made of a thermoplastic elastic resin form a random loop, and the contacts of the lines are fused to each other. Has been done. Examples of the thermoplastic elastic resin forming the three-dimensional network structure 271 include thermoplastic resin elastomers such as polyester-based, polyolefin-based, and polyurethane-based. Examples of the three-dimensional network structure 271 include those described in Japanese Patent No. 4802369.

The thickness dimension t1 of the cushion material 27 is, for example, preferably 5 mm or more and 70 mm or less, and more preferably 10 mm or more and 50 mm or less. When the thickness dimension t1 of the cushion material 27 is 5 mm or more, the air flow path can be secured even when an external force is applied to the cooling clothes 2. When the thickness dimension t1 of the cushion material 27 is 70 mm or less, the wearing feeling of the cooling clothes 2 is not impaired, and the comfort of the cooling clothes 2 can be improved.

The bulk density of the cushion material 27 ^{is preferably 10 kg / m 3} or more and 100 kg / m ³ or less. When the bulk density of the cushion material 27 is 10 kg / m ³ or more, an air flow path can be secured even when an external force is applied to the cooling clothes 2. When the bulk density of the cushion material 27 is 100 kg / m ³ or less, the wearing feeling of the cooling clothes 2 is not impaired, and the comfort of the cooling clothes 2 can be improved.

Further, the cushion material 27 preferably has a recovery rate of 70% or more, more preferably 80% or more, after being compressed by 50% in the thickness direction. When the recovery rate after compressing the cushion material 27 by 50% in the thickness direction is 70% or more, an air flow path can be appropriately secured even when an external force is repeatedly applied to the cooling clothes 2.

It is preferable that the cushion material 27 is arranged not on the entire inner surface of the cooling clothes 2 but on a part thereof. In the present embodiment, the back of the wearer's body, is arranged in a position facing the shoulder and chest, and the total area of the cushion member 27, 50% of the area of the predecessor around 22 and the rear body around 21 or less, preferably It is set to 30% or less. As a result, it is possible to prevent the air flow in the cooling clothes 2 from being obstructed by the cushion material 27.

The inside of each container 612 and the inside of the housing body 611 communicate with each other. Examples of the material of the housing 61 include metal, synthetic resin, carbon, wood, pulp and the like, but from the viewpoint of strength, heat dissipation and light weight, it is preferable to use a metal made of aluminum.

The fan 62 is provided in the air flow path and generates a flow along the air flow path. The fan 62 is housed in the housing body 611. The fan 62 operates by receiving electric power from a battery (not shown) detachably attached to the outside of the housing 61.

The adsorbent 63 is housed in the container 612. The adsorbent 63 is a fibrous activated carbon, and can purify the air by absorbing gaseous harmful substances contained in the air that has passed through the adsorbent 63.

The fibrous activated carbon can handle a wide range of gases, has a large adsorption rate and adsorption capacity, and can obtain an effective gas permeation suppressing ability even when used in a small amount.

The gaseous harmful substance to be adsorbed may be, for example, a gaseous compound having one or more carbon elements. Such a gaseous compound includes, for example, a gaseous chemical substance having a relatively large molecular weight of 50 or more and capable of being adsorbed by the gas adsorption layer 2. Specific examples thereof include organophosphorus compounds used in pesticides, pesticides and herbicides, and general organic solvents such as toluene, methylene chloride and chloroform used in painting operations.

The BET specific surface area of the fibrous activated carbon ^{is preferably 700 m 2} / g or more and 3000 m ² / g or less, and ^{more preferably 1000 m 2} / g or more and 2500 m ² / g or less. If the BET specific surface area is less than the above range, a large amount of activated carbon is required to obtain a sufficient adsorption amount for the gaseous compound, the material becomes heavy, and there is a concern that the flexibility is inferior. On the other hand, if it exceeds the above range, a problem that the gas adsorbent becomes brittle may occur.

The mass (absolute dry mass) of the fibrous activated carbon contained in the adsorbent 63 ^{is preferably 50 g / m 2} or more and 300 g / m ² or less, and more preferably 70 g / m ² or more and 250 g / m ² or less. If the mass is less than the above range, there is a concern that the capacity that can be adsorbed becomes small and the scattering suppression performance of the gaseous compound becomes low. On the other hand, if it exceeds the above range, there is a concern that the flexibility of the material will be inferior.

As raw materials for fibrous activated charcoal, in addition to natural cellulose fibers such as cotton and hemp, recycled cellulose fibers such as rayon, polynosic, and solvent spinning method, as well as polyvinyl alcohol fibers, acrylic fibers, aromatic polyamide fibers, lignin fibers, and phenols. Examples thereof include synthetic fibers such as system fibers and petroleum pitch fibers. Regenerated cellulose fibers, phenolic fibers, and acrylic fibers are preferable from the viewpoint of physical characteristics (strength, etc.) and adsorption performance of the obtained fibrous activated carbon.

The fibrous activated carbon can be produced by a conventionally known method. For example, a fabric woven, knitted, or non-woven fabric using the short fibers or long fibers of the above-mentioned raw material fibers is impregnated with an appropriate flameproofing agent as necessary, and then flameproofed at a temperature of 450 ° C. or lower. It can be produced by applying and then carbonizing and activating at a temperature of 500 ° C. or higher and 1000 ° C. or lower.

The fibrous activated carbon preferably has a fiber diameter (diameter) of 5 μm or more and 40 μm or less, for example. Since the fibrous activated carbon has a larger specific surface area than, for example, the granular activated carbon, the size of the apparatus main body 6 can be reduced as compared with the case where the granular activated carbon is used as the adsorbent 63.

The adsorbent 63 preferably has any form of woven fabric, knitted fabric, non-woven fabric, or felt. Of these, the form of the woven fabric or knitted fabric is more preferable in terms of breathability, ease of lamination, flexibility and the like. The thickness and filling amount of the adsorbent 63 may be appropriately designed as needed. If the case filled with the adsorbent 63 is, for example, 10 mm to 50 mm, it is easy to reduce the size of the blower 3.

The bulk density of the adsorbent 63 is preferably not more than 0.02 g / cm ³ or more 0.25 g / cm ^3, more preferably is 0.05 g / cm ³ or more 0.20 g / cm ³ or less. If the bulk density of the adsorbent 63 ^{is less than 0.02 g / cm 3} , appropriate purifying performance may not be obtained, and if it ^{exceeds 0.25 g / cm 3} , the ventilation resistance becomes large and the apparatus It is difficult to achieve miniaturization. ^{The adsorption amount of the adsorbent 63 is preferably 30 g / m 2} or more in the toluene adsorption performance according to JIS K 1477 “Fibrous Activated Carbon Test Method”.

The adsorbent 63 according to the present embodiment has a circular cross section orthogonal to the air flow path. However, in the present invention, the shape is not limited to a circular shape, and may be, for example, a quadrangular shape, a triangular shape, a pentagonal shape, or the like.

The adsorbent 63 according to this embodiment is housed in a pair of containers 612. Each of the pair of containers 612 contains an adsorbent 63 containing fibrous activated carbon, but only one container 612 may be attached. Further, the adsorbent 63 and the moisture absorbing material may be laminated and stored in each container 612.

The hygroscopic material adsorbs water vapor contained in the air. As the moisture absorbing material, it is preferable to use a large number of granular materials having pores in order to improve the adsorption ability. Examples of the hygroscopic material include silica gel, zeolite, activated alumina, calcium chloride and the like.

Further, the heat storage material may be accommodated together with the moisture absorbing material. Since the adsorption of water vapor by the moisture absorbing material is an exothermic reaction, heat of adsorption is generated in the moisture absorbing material as the water vapor is adsorbed. The temperature rise of the air that has passed through the material is suppressed. Therefore, even if the air taken into the air flow path contains a large amount of water vapor, it can be sent out to the supply port 211 as dry low-temperature air.

As the heat storage material, for example, a large number of heat storage capsules in which a phase-changing substance that absorbs latent heat depending on the temperature is encapsulated in a capsule or the like can be used. As the heat storage capsule, those described in Japanese Patent No. 45088867 and Japanese Patent No. 4861136 can be used.

Since the container 612 is detachably attached to the housing body 611, if the suction force of the adsorbent 63 decreases, it can be replaced with a new adsorbent 63. As a result, appropriate adsorption performance can always be exhibited.
