Description

  The invention relates to a stretch pillow that exhibits a stretch effect at bedtime.

  Social needs on the theme of sleep disorders such as restful sleep and deep sleep are enormous. Therefore, many well-known inventions from the viewpoint of pillows have been devised to solve sleep disorders.

  For example, as in the registered utility model No. 3072901, the pillow body is configured with a gusset so that the thickness of the body can be changed, the padding configured inside can be changed, and the pillow height can be adjusted. There are known inventions.

  However, in the registered utility model No. 3072901, the act of changing the stuffing included therein is complicated by the user, and a great effect on the sleep and the deep sleep cannot be expected.

  For example, as disclosed in JP 2000-350649 A, there is a known invention in which a depression is formed so that the head enters so that the head is lower than the neck, and the neck is supported.

  However, Japanese Patent Laid-Open No. 2000-350649 has a disadvantage that the sleeping comfort changes depending on the physique such as the height of the user and the depth of the back of the head, and the feeling of use becomes worse depending on the user.

  For example, as disclosed in Japanese Patent Application Laid-Open No. 2000-70094, there is a known invention that attempts to adjust the height by adjusting the number of a plurality of height adjusting members configured in substantially the same shape as the lower surface of the pillow body.

  However, in Japanese Patent Laid-Open No. 2000-70094, if a plurality of height adjusting materials are enclosed in advance in a product, unnecessary merchandise is supplied to the purchaser. The purchaser will purchase additional height adjustment materials that need to be purchased, which will reduce the convenience for the purchaser. The cost increases due to the increase in the number of the adjustment materials, and the complexity increases for the user as in the registered utility model No. 3072901.

  For example, as disclosed in Japanese Patent Application Laid-Open No. 2003-245181, the height of the convex pillow is basically adjusted using three types of a basic pillow and a height fine adjustment pillow. An invention intended to support the shoulder blade at the same time by forming a groove on the contact surface with the convex pillow on the upper surface of the pillow to support the head by forming a groove in the direction intersecting the convex portion of the convex pillow and further supporting the shoulder blade on a part of the pillow There is.

  However, the Japanese Patent Laid-Open No. 2003-245181 discloses that if the head is extremely depressed or bent, the forehead bends to the outside of the body, and depending on the sleeping posture, a burden is applied to the neck to prevent sleep and deep sleep. There is a problem in achieving.

  The Japanese vocabulary vocabulary is sometimes replaced with a cushion, which is another vocabulary. For example, in the technical field of cushioning material, which has the meaning of a cushion, to the butt and back of the user Although there is an invention of Japanese Patent No. 4173675 which is conscious of the effect of the above, it is not intended for direct action on the body such as the head and neck which is the purpose of the action in the present invention, and has been conventionally used for furniture. Therefore, the point of view of the intended function of the invention and the structure therefor is completely different.

  When each of the above-mentioned known inventions has been drafted, there is no scientific result of the act of sleeping, and there is a side that is far from the invention based on medical findings, and there is a pillow at the end. It can be said that the present invention focuses only on the user's sense of being high, low and hard and soft and is a drawback of the prior art.

  Both are generally effective when the user is limited. For example, when assuming an unspecified number of users such as lodging facilities, or when selling as a general-purpose product, the physique and gender of the user, Convenience in providing versatility in consideration of age and the like will be greatly reduced.

Registered Utility Model No. 3072901 JP 2000-350649 A JP 2000-70094 A JP 2003-245181 A Japanese Patent No. 4173675

  Sports, desk work, housework, etc., usually take a forward bending posture, increasing the burden on the neck and shoulders, causing neck pain. In addition, it is an unreasonable posture and causes shoulder pain or stiff shoulders.

  For example, many modern people suffer from neck and shoulder pain due to the leaning forward posture and lack of exercise during PC work. In addition, for example, volleyball athletes have a heavy burden on their necks and often suffer from neck pain and stiff shoulders. In addition, volleyball is basically leaning forward, so it is easy for the body to shrink, which is a trap for normal standing posture. I practice stretching carefully before and after practice and games, but my body shrinks while sleeping and it is difficult to breathe, so I often stretch after waking up.

  In order to eliminate neck pain and shoulder pain, it is effective to perform stretching exercises called stretching, and especially to open the back of the body centering on the scapula to relieve muscle fatigue. In addition, it is often difficult to continuously perform stretching, which is said to be effective for improving shoulder pain and stiff shoulders, due to individual differences such as the convenience of time and physical condition of the day. For this reason, fatigue accumulates and shoulder pain or stiffness occurs unexpectedly, and when subjective symptoms are born, it cannot be easily resolved, and sleep disorders due to shoulder pain and stiffness are occurring.

  In order to solve such a problem, it is the best method to adjust the environment in which stretching can be performed regularly in the time of the day and to perform the treatment suitable for the individual condition.

  Considering the longest time that a person's body can remain in a natural resting state and being freed from daily activities during the day, sleeping is the best condition for everyone. In other words, if the body naturally stretches during bedtime, it should be possible to stretch regularly without difficulty, and everyone should be able to expect to be able to heal naturally from shoulder pain and stiffness.

  In particular, a lot of inventions have been made with respect to bedding called pillows from the viewpoints of a good night's sleep and deep sleep, but from a medical point of view, the stretch effect during sleep has been improved, and as a result, the viewpoint of solving a good night's sleep and deep sleep was poor.

  Each part of the body does not usually feel the unit weight of the head, neck, etc., but the unit weight they have varies unexpectedly, and there are also weight differences depending on age, physique and gender . There are also individual differences depending on age and physique. Therefore, it is the best way for users to produce pillows with the optimal conditions for individuals, but considering the production cost and distribution method, there is a lot of waste and the market supply price is The merit is poor. Therefore, it is necessary to deal with individual differences among users as widely as possible, and to realize appropriate costs and selling prices.

  Therefore, the present inventor has come to the conclusion that there is no pillow that can sleep in an ideal posture even during sleep, and has invented a stretch pillow that fully exerts the stretch effect during sleep and leads to good quality sleep by stretching. It was. The present inventor studies shoulder pain and stiff shoulders, sleep and deep sleep, and conditions necessary to improve those symptoms, and takes measures to solve the problems that have not been completely solved so far as pointed out above. It was decided.

  This invention is a stretch pillow provided with the stretch part which gives the stretch effect to a chest. A recess for receiving the head is provided on one side of the central part, and a stretch part is provided on one side of the central part of the pillow core.

  The present invention combines a rebound material having a hardness difference divided into a plurality of parts in order to exert a stretch effect while sleeping, and further, atypical repulsion material so as to effectively maintain a difference in weight of the neck, head, shoulder, and back Is a stretch pillow that incorporates a cushion layer that is a core material from the viewpoint of sports medicine.

  In the present invention, the pillow core is composed of one or a plurality of cushion layers, the stretch portion is located in the region of the concave portion, and the stretch is provided so that the specific portion where the cervical spine hits is thicker than the adjacent region. It is a pillow.

  The present invention is characterized in that the cushion layer is configured by combining a plurality of repulsive materials having a difference in hardness, and the vertically elongated stretch portion is incorporated in a specific position at the center of one side of the cushion layer in the front-rear direction.

  In the present invention, the stretch portion is made of a material having a higher density or a higher hardness than the material of the cushion layer.

  In the present invention, the pillow core is composed of an upper cushion layer composed of one or more cushion materials, an intermediate cushion layer composed of one or more cushion materials, and a lower cushion material composed of one or more cushion materials. A first stretch portion is formed from the upper cushion layer, the middle cushion layer, or an intermediate portion between the upper cushion layer and the middle cushion layer from the recessed portion to the rear, and the middle cushion layer and the lower cushion layer. Or the 2nd stretch part is comprised from the said recessed part to the back in the intermediate part of a middle cushion layer and a lower cushion layer.

  Furthermore, in order to make sleeping comfort more comfortable, the stretch pillow according to the present invention is covered with an outer skin made of a breathable material.

  With the stretch pillow of the present invention, the stretch effect during sleeping is exhibited so much that not only the degree of deep sleep and the degree of sleep are improved by the user, but also the degree of feeling of shoulder pain and stiff shoulder that have always been a problem.

  In particular, there is a degree of freedom in the morphological differences during bedtime caused by turning over, etc. due to the relationship with the head, neck, and shoulder, and as a result, the form that requires the head, neck, and shoulder, whether lying on its back or lying down on its side Therefore, it is possible to suppress pain in the neck muscle, which is often called sleeping, and frequently occurs during sleep.

  Of course, since the shoulder pain and the stiff shoulder from the time of getting up to the daytime can also be suppressed, the stretch pillow of the present invention has a great effect.

  The stretch pillow of the present invention achieves a low cost by combining a general-purpose cushion layer, and as a result, the selling price can be kept lower than other pillows having similar special functions and can be purchased in the market. It has become a cost.

  Not only the functional effects but also the cost effects are at a level that can sufficiently handle not only purchases by individual users such as general households but also an unspecified number of uses such as accommodation facilities. Therefore, it can be expected to be applied to automobiles, trains, airplane pillows, etc., and its manufacturing process is at a cost level that can be manufactured, and a wide range of economic effects can be expected.

It is a disassembled perspective view of the pillow core of the stretch pillow according to the embodiment of the present invention. It is a use condition reference drawing of this invention embodiment stretch pillow. It is a top view of the change form of the stretch pillow of this invention embodiment.

  Hereinafter, a preferred embodiment of the stretch pillow 1 of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 2, the stretch pillow 1 is composed of an upper epidermis 2, a lower epidermis 3, an upper epidermis 2 and a pillow core 4 covered with the lower epidermis 3.

  In order to maximize the features of the stretch pillow 1 itself, the upper skin 2 has a large size and a large contact area with the body in order to make use of the fluffy feel. In addition, a knitted mesh fabric was used. The material is, for example, 100% polyester.

  The lower skin 3 is a material in which polyester fibers are contained more than cotton so as not to be easily displaced and, for example, 65% polyester fibers and 35% cotton, and is not easily deformed. The same fabric is used to wrap around the area. The lower skin 3 is large but thin and light, so it is easy to carry. Not only can you use it in a bed or futon, it can be easily carried to the living room for a nap. A refreshing refreshment can be achieved with a good quality sleep and stretch effect even in a short time.

  The upper skin 2 may be composed of a single type of material, but in order to realize a more comfortable sleep environment, for example, it is preferable to use a material having as much breathability as possible in order to improve sleeping comfort. For the upper skin 2 that the body hits, a material having excellent air permeability such as a knit mesh fabric is desirable. The material of the lower epidermis 3 is a material that can prevent the movement of the stretch pillow 1 that occurs when the user's body moves, such as turning over, or when it rubs with a futon or the like, or because the coefficient of friction is small Is preferred.

  The stitched portions 9 of the upper skin 2 and the lower skin 3 may be stitched as they are, or may be subjected to a design process.

  As shown in FIG. 3, the pillow core 4 is composed of a plurality of cushion layers, and is composed of an upper cushion layer 5 composed of one cushion material and two cushion materials 6a and 6b in order from the top. A middle cushion layer 6 and a lower cushion layer 7 made of one cushion material are provided.

  The cushion layers 5 to 7 are configured by combining a plurality of repulsive materials having a difference in hardness.

  The upper cushion layer 5 is a foam layer such as a low-resilience urethane foam having a thickness of 2 to 4 mm. The middle cushion layer 6 is prevented from collapsing, and a soft repulsive force is generated at the moment of touching.

  The middle cushion layer 6 is a cotton made of microfiber that is thin and difficult to loosen. The upper cushioning material 6a has excellent fluffiness and softly wraps the entire head. The lower cushion is made of soft urethane with a thickness of 7-9mm. It is comprised from the lower cushion material 6b supported by.

  The lower cushion layer 7 is made of a foam layer such as a hard urethane foam having a thickness of 2 to 25 mm, and is a base that supports the entire head.

  When viewed from the upper surface, the upper cushion layer 5, the middle cushion layer 6, and the lower cushion layer 7 are each configured in a substantially identical shape, and the protruding portions 15 and 16 are also configured in the same shape.

  It is preferable that the 1st stretch part 20 and the 2nd stretch part 30 are comprised from the material whose hardness is higher than the material of the cushion layers 5-7. Further, since the thickness of the first stretch part 20 and the second stretch part 30 is formed so as to rise as a pedestal part in the region of the recess 10, when the head 50 is in the normal position on the pressure receiving surface, the cervical vertebra 60 is By supporting to lift, it is formed so that both shoulders are lowered and the chest muscles are opened when sleeping on its back.

  The first stretch portion 20 is preferably bonded to the back surface of the upper cushion layer 5 or the upper surface of the upper cushion material 6 a of the middle cushion layer 6. An adhesive method is not selected, but in consideration of the properties of the product as the stretch pillow 1, an adhesive method such as adhesion with a thermosetting resin or ultrasonic welding that does not use a solvent capable of avoiding odor due to organic gas is desirable.

  Each of the upper cushion layer 5, the middle cushion layer 6, and the lower cushion layer 7 may be composed of one cushion material, or may be composed of two or more cushion materials. In the case of two or more cushion materials, those having the same hardness and the same thickness may be used, or cushion materials having different hardnesses and different thicknesses may be used.

  The cushion material used for the upper cushion layer 5, the middle cushion layer 6 and the lower cushion layer 7 is preferably a cushion material such as a thermoplastic foamed polyethylene resin or a thermosetting foamed urethane resin. A cushioning material such as a plastic resin, a thermosetting resin, a metal foam material, a cotton material, a material called a three-dimensional three-dimensional network structure, or a nonwoven fabric can be used. These cushion materials may be used alone or in combination.

  The cushion material of the middle cushion layer 6 is preferably a cotton-like cushion material in order to achieve the effect of adjusting the shape of the entire pillow.

  A recess 10 for receiving the head 50 is provided on one side of the center of the pillow core 4. When the stretch pillow 1 is viewed from the upper surface, the concave portion 10 is formed from the front center to the rear, and the protruding portions 15 and 16 are formed on the left and right sides of the concave portion 10.

  The first stretch portion 20 is formed so as to be sandwiched between the upper cushion layer 5 and the middle cushion layer 6. The first stretch portion 20 is made of soft urethane having a thickness of 7 to 9 mm, and is disposed on the upper cushion material 6 a to support the cervical vertebra 60. Further, the second stretch portion 30 is formed so as to be sandwiched between the middle cushion layer 6 and the lower cushion layer 7. The second stretch portion 30 is made of hard urethane with a thickness of 15 to 25 mm, and supports and lifts the cervical vertebra 60. The positions of the first stretch portion 20 and the second stretch portion 30 are not limited and can be changed as appropriate. The number of the stretch portions 20 and 30 may be singular.

  A first stretch portion 20 that is thicker than the upper cushion layer 5 and has a smaller area and a higher hardness is formed on the middle cushion layer 6 from the recess 10 to the rear. On the upper portion of the lower cushion layer 7, a second stretch portion 30 is formed that is thicker than the lower cushion material 6 b of the middle cushion layer 6, has a smaller area, and has a higher hardness from the recess 10 to the rear.

  The stretch portions 20 and 30 are vertically long and are arranged so as to support the cervical vertebra 60 along the direction of the head, and the stretch portions 20 and 30 are incorporated in a specific position at the center of the recess 10 in the front-rear direction in plan view. . A material in which the second stretch portion 30 is harder than the first stretch portion 20 is preferable. Here, both the stretch parts 20 and 30 are foam layers, such as a urethane foam, for example.

  Thus, since it is incorporated between the upper cushion layer 5, the middle cushion layer 6, and the lower cushion layer 7, the first stretch portion 20 functions to support the load from the head 50, and the second stretch portion 30 It fulfills the function of conveying the repulsive force from below.

  Thus, by providing the stretch portions 20 and 30 at specific locations located in the recess 10 and supporting the cervical vertebra 60 to lift, the sternocleidomastoid muscle is neutral or slightly stretched when lying on its back Or the chest muscles are formed to open.

  The features of the stretch pillow 1 of the present embodiment are that it feels comfortable and cushioned at the moment when the head is put on, and as a result of various types of batting, the upper cushion 6a of the middle cushion layer 6 has a smooth, feather-like texture. This is the adoption of microfiber cotton that gives a fluffy feel. Microfiber is a chemically composed ultrafine nylon or polyester fiber with a thickness of 8 micrometers or less, and is a material with water absorption, breathability and heat retention equivalent to or better than cotton. Microfiber cotton, which is thinner and harder than normal polyester cotton, has a low rebound upper cushion layer 5, a medium rebound middle cushion layer 6 that has a higher repulsive force than the upper cushion layer 5, and is higher than the middle cushion layer 6 Lower cushion layer 7 with high resilience, each layered with 3 types of urethane with different hardness, and by adopting a fabric with excellent elasticity, the cushioning properties are easy to turn over without being too soft and not too hard Is.

  The stretch pillow 1 has a particular size and shape. The overall thickness is 70 mm, the length is 600 mm, and the width is 700 mm, and it is a large size that wraps around from the scapula to the head. About 1.5 to 2 times the vertical size (about 43 cm) of a normal pillow is preferable. Specific examples of the thickness include an upper cushion layer 5 of 3 mm, a first stretch portion 20 of 8 mm, a lower cushion material 6b of 8 mm, a second stretch portion 20 of 20 mm, and a lower cushion layer 7 of 25 mm. The concave portion 10 is curved like a hilly surface, is maximally scooped at the center portion, is gently inclined toward the scapula, and a pair of protruding portions 15 and 16 protrude from the left and right like a cape. It fits the shoulder blades, shoulders, neck, and head in any sleeping position, so it doesn't create a gap with the pillow that puts a load on the body, and keeps the ideal sleeping position that does not obstruct breathing. Stretching the chest is effective to alleviate them. The stretch pillow 1 for stretching has a special structure in which the stretch portions 20 and 30 where the cervical vertebra 60 rides are thickened so that the chest naturally opens.

  There are many types of stretch, but the simple and effective is to open the chest. By opening the chest, the constriction of the sternocleidomastoid muscle, which is often seen in modern people, can be extended, the greater pectoral muscles can be stretched, and the back muscles and neck can be naturally positioned correctly to breathe easily. Being able to breathe easily can take in more oxygen into the body. The sternocleidomastoid muscle mainly acts to bend and rotate the neck. On the other hand, those who are in a habit of not opening the chest are constricted by the sternocleidomastoid muscles, causing the neck to come forward, the back muscles to bend, and strain the neck, shoulders and waist In addition to becoming better, breathing becomes shallower than good posture. Naturally, the posture while sleeping is also very important. In order to maintain a good state with the chest open, it is necessary to always maintain a good posture in daily life. This stretch pillow 1 has the effect of being able to stretch the chest naturally just by sleeping.

  Good sleep means being in the right posture, breathing easily, and sleeping well. To do so, when sleeping on the back, the muscles in front of the neck (front of the neck) (clavicle mastoid) are neutral or slightly stretched, or the chest muscles (such as the large pectoral muscle) are opened (stretched). The state is desirable. Use the stretch pillow 1 with a relatively small height that supports the cervical vertebra 60 with a large size that rides from the head to the scapula. Will guide you. In addition, the material is used to realize a fluffy and soft feel and ease of turning over.

  The stretch pillow 1 has a discerning shape and a cushion layer having a stretch effect. About 400g of upper cushioning material 6a made of fluffy microfiber cotton is put on the lower cushioning material 6b made of hard urethane that firmly supports from below, and about 3.6cm of urethane that supports the cervical vertebra 60 in the center. The 1st stretch part 20 is bonded together from the sheet | seat. As shown in FIG. 4, the stretch pillow 1 has a large size and is gently inclined toward the recess 10 where the scapula strikes. The height is about 12 cm at the highest position, and the cervical vertebra 60 is about 6 cm. When the head is positioned slightly above the stretch pillow 1, the neck is stretched by supporting the cervical vertebrae with the stretch portions 20 and 30, and the recess 10 adjacent to the stretch portions 20 and 30 is used. Both sides are designed to be slightly lower so that the shoulders fall to the left and right, inevitably opening the chest muscles.

  As shown in FIG. 5, the stretch pillow 101 according to the modified embodiment is obtained by stitching the first stretch portion 20 and the upper cushion layer 5 of the above-described embodiment by providing the seam 80. The seam 80 is 20 mm long and 8 mm wide. Thereby, the boundary between the stretch portions 20 and 30 and other regions becomes clear. Note that a pocket may be provided in the stretch pillow 101 so that the first stretch portion 20 is accommodated in the pocket.

Upper cushion layer 5 thickness 3mm, density 35kg / m ³ , middle cushion layer 6 thickness 8cm, lower cushion layer 7 thickness 2.5cm, density 30kg / m ³ , stretch part 20mm 8mm, density 18kg / m ³ , stretch The thickness of the part 30 is 2 cm, and the density is 30 kg / m ^3, but is not limited thereto. The upper cushion layer 5, the lower cushion layer 7, the stretch portion 30, and the stretch portion 20 are arranged in descending order of density. The density of the middle cushion layer 6 can be set as appropriate. Although the middle cushion layer 6, the lower cushion layer 7, the stretch part 30, the stretch part 20, and the upper cushion layer 5 are illustrated in order of increasing thickness, it is not limited and can be set as appropriate.

  Stretch pillows for the purpose of treating shoulder pain and stiff shoulders, spread pillows for general use and sleep in general homes and accommodations, stretch pillows for hospitalized patients in hospitals, elderly care facilities It has the potential for a wide range of uses as stretch pillows for residents, buses and trucks, sleeper trains, and stretch pillows for aircraft.
