Description

  In particular, the present invention relates to a pillow having excellent breathability, heat dissipation, elasticity, and stable head and neck stability.

  Conventionally used pillows are generally made by filling stuffed bags made of various materials into an exterior cloth bag. Pillows made of plant material such as buckwheat husks and breads have good breathability to effectively absorb and dissipate heat and sweat from the head, but they are inferior in cushioning and in the head during use. Since the padding is shifted to the corner of the outer cloth bag due to the weight of the part and deformed into a state where the center part is recessed, it is not possible to promote a comfortable sleep while turning over in a natural state. In addition, pillows made from plant materials such as cotton and feathers or granular or ball-shaped inorganic materials have the advantage of maintaining a stable pillow shape that is easy to adjust to the head, but are inferior in breathability and elasticity. There are drawbacks. Furthermore, pillows made from materials made of chemical products such as urethane foam and plastic have a very good elasticity, but they are inferior in moisture permeability and heat storage, so they are easily stuffy. Heat and sweat from the head are easily trapped inside, and when the head is subjected to a load, it easily deforms and bottoms out easily. In other words, any pillow that has a structure in which the stuffing is simply filled in the exterior cloth bag has advantages and disadvantages depending on the type of stuffing, and a pillow that can promote a comfortable sleep cannot be obtained.

  Therefore, conventionally, pillows of various structures have been proposed, and as one of them, each of the random loops formed by winding a continuous filament having a diameter of 5 mm or less made of a thermoplastic resin and contacting each other. The three-dimensional structure network obtained by fusing each part is shaped into a rectangular parallelepiped flattened on both sides to form a core, and the core is formed on both surfaces of a natural fiber or synthetic fiber web layer. A pillow has been proposed that is wrapped with a knitted fabric and wrapped in a bag-like side fabric (see, for example, Patent Document 1). This bag is a three-dimensional mesh body that receives a load from the placed head, so it is greatly elastically deformed to sink into the shape along the head and softens the head and neck. The core can be supported by touching, and when the deformation stress due to the head is released, the core can be restored to its original state by its own elastic force. Along with the structure having a high porosity, the air permeability is remarkably good, so that there is a feature that it is difficult to be steamed.

  In addition, as another conventionally proposed pillow, a soft cushion material made of soft urethane foam is used for the entire outer peripheral surface of the core material formed in a rectangular parallelepiped plate shape by a semi-rigid material having a certain degree of elasticity. A plurality of heat dissipating parts formed by filling a small bag body with fine stones having a particle size of about 3 to 5 mm on the upper surface on which the head portion of the exterior bag body is placed in a wrapped state. A stitched one is known (for example, see Patent Document 2). This pillow has a moderate cooling sensation by absorbing heat from the user's head with multiple heat sinks, and a semi-rigid core prevents large deformations to achieve the required pillow effective height. This is intended to maintain this. Further, in this pillow, a concave curve portion is formed in which the central portion of one side in the longitudinal direction is recessed inward, and the distance from the space provided by sewing the partition cloth inside the concave curve portion. The structure which accommodated and sealed red cotton is provided. As a result, in this pillow, it is possible to prevent the cooling of the shoulder by closing the gap of the bedding that is easy to be made at the shoulder and the concave curve part from the neck part of the human body to both shoulder parts and blocking it, and by electromagnetic waves radiated from far-red cotton It is intended to obtain a good heat retention effect.

Furthermore, conventionally, a pillow that can be adjusted so that the head and the cervical vertebra having different shapes for each user can be supported at the correct pillow height corresponding to the user has been proposed (see, for example, Patent Document 3). . This pillow has a pillow body in which a pillow body bag is filled with padding and the upper surface is formed in a shape that matches the curved surface from the head of the human body to the neck, and the head and neck of the pillow body are respectively mounted. A head height adjusting bag and a neck height adjusting bag are integrally formed on the lower surface portion facing each other, and the head height adjusting bag and the neck height adjusting bag are integrally formed. The height for supporting the head of the pillow body and the cervical vertebra can be individually adjusted according to the number of height adjustment pads accommodated in each.

  However, all of the pillows of the inventions according to Patent Documents 1 to 3 still have problems to be improved. That is, as described above, the pillow of the invention according to Patent Document 1 has various features necessary for the pillow, but on the other hand, the core composed of a three-dimensional network is formed on both sides of the fiber web layer. Deformation by the head and neck to be placed because there is no hard or semi-rigid support member because it is wrapped in a sack-like side cloth covered with knitted fabric and quilted. Almost all of the stress is applied to the core. The core core itself deforms and receives deformation stress with a low repulsive force, so extreme local sinking does not occur, but the gripping force is too soft for the head and neck. It is difficult to achieve stable support, and the pillow height is likely to change every time the mounting position of the head and neck and the weight thereof change, and it is difficult to keep the pillow height constant.

  In addition, as described above, the pillow of the invention according to Patent Document 2 has an advantage that it can prevent a large deformation by the core material and maintain the required pillow effective height, but a semi-hard core material and a flexible urethane foam, etc. Because it only supports the head and neck with the elasticity of each soft cushion material, it cannot be elastically deformed into a suitable shape that fits the head and neck due to insufficient elasticity. In addition, there is a problem in that the stability of the head and neck is insufficient, and the cervical vertebra retainability is lowered due to the lack of elasticity and the tendency to bottom out and the chin to rise. In addition, this pillow has good heat dissipation due to the fine stones of the heat radiating part, but because the soft cushion material such as soft urethane foam disposed below the heat radiating part has heat storage property There is a fault that is easy to get stuffy. Furthermore, the concave curve portion formed on the pillow is provided on the assumption that shoulder cooling is prevented by contacting from the head of the user in the supine posture to both shoulders. In this case, a gap in which the bedding is opened is easily formed in the shoulder and, in addition, the presence of the concave curve portion may prevent natural turnover during sleep. On the other hand, the heat retention effect by electromagnetic waves radiated from far-red cotton may cause a troubled state that acts on the head due to position shift due to turning over.

  Furthermore, the pillow according to the invention according to Patent Document 3 is a height that supports the head and cervical vertebrae of the pillow body by the number of height adjustment pads accommodated in the head height adjustment bag and the neck height adjustment bag, respectively. The height can be adjusted individually, but the adjustment work is to open the entrance by opening the slide fastener or Velcro fastener for opening and closing the entrance of each of the head height adjustment bag and the neck height adjustment bag. After inserting or taking out the required number of height adjusting pads from the entrance, it is necessary to perform the procedure of closing the entrance by closing the fastener, which is complicated.

As described above, each of the pillows of the inventions according to Patent Documents 1 to 3 has advantages and disadvantages, breathability, heat dissipation, stability of head and neck stability, elasticity, sag resistance and There are no pillows that have all the essential functions of pillows, such as the required pillow effective height retention, and the height of the pillow is easy to adjust and looks good. There is also no object that has a function to prevent the cooling of the shoulder even when the shoulder is cold. Further, in the pillow proposed in the past, a support portion formed in advance so as to be able to support the occipital region and neck portion of the human body to be welcomed is disposed in the center of the upper surface, and lying on both sides. Many of these pillows are formed with support for the side of the human body, but such pillows are difficult to lie down with a natural turn during a sleep. Since the height of the pillow is different between the heel and the bubo, it is not possible to promote a comfortable sleep.

  The present invention provides a pillow having functions such as breathability, heat dissipation, stability of head and neck stability, elasticity, sag resistance and required pillow effective height retention, and further In addition, the pillow height can be adjusted with easy operation, and the pillow height adjustment means has a good-looking appearance, as well as a function to prevent shoulder cooling even when turning over. The purpose is to provide a pillow.

  In order to achieve the above object, the pillow according to the first aspect of the present invention has a length of 500 to 700 mm, a width on which the head and neck of a human body can be placed, and a width of the head and neck of a lightweight material having plasticity. A pillow core formed in a rectangular parallelepiped having a thickness that can be bent in a curved shape according to a load due to placement, and a thickness of 1/5 to 3/5 of the thickness of the pillow core Most of each contact portion of a random loop formed by winding a flexible sponge-like sheet material disposed so as to cover at least the entire upper surface of the pillow core and a continuous filament made of thermoplastic elastic resin Are formed in a rectangular parallelepiped having substantially the same length and width as the pillow core and a thickness slightly smaller than the thickness of the pillow core, Above the pillow core with a soft sponge-like sheet material interposed A three-dimensional structure cushion body laminated on the pillow core, and characterized in that it comprises an exterior fabric housed inside while laminating the soft spongy sheet material and the conformation cushion body.

  The pillow according to a second aspect of the present invention is the invention according to the first aspect, wherein the soft sponge-like sheet material is made of urethane foam having a thickness of 1/10 to 3/10 of the thickness of the pillow core, It is wound around the outer peripheral surface of the pillow core so as to cover the upper surface in a double layer and the lower surface in a single layer.

  The pillow according to the third aspect of the present invention has a length of 500 to 700 mm, a width capable of placing the head and neck of a human body, and a curvature according to a load caused by placing the head and neck using a lightweight plastic material. A pillow core formed in a rectangular parallelepiped having a thickness that can be bent into a shape, and a thickness of 1/5 to 3/5 of the thickness of the pillow core, and at least the entire upper surface of the pillow core is A three-dimensional structure in which the majority of each contact portion of a random loop formed by winding a continuous spongy sheet made of thermoplastic elastic resin and a soft sponge-like sheet material provided to cover each other is connected. The net-like body is formed in a rectangular parallelepiped having substantially the same length and width as the pillow core body and having a thickness slightly smaller than the thickness of the pillow core body, with the soft sponge sheet material interposed therebetween. A three-dimensional structure cooked on the top surface of the pillow core. Natural cotton inside the cylindrical storage bag having the same length as the pillow core body and the same diameter as the stacked height of the pillow core body, the soft sponge sheet material and the three-dimensional structure cushion body. The two heat insulating members formed by filling the heat insulating material that freely deforms, and the pillow core body in the laminated state, the soft sponge sheet material, and the three-dimensional structure cushion body on the both sides thereof It is characterized by comprising an exterior cloth housed inside with two heat retaining members applied to each other.

The pillow according to a fourth aspect of the present invention is the pillow according to the third aspect, wherein the two core members, the soft sponge-like sheet material, and the three-dimensional structure cushion body are laminated on the both side surfaces of the pillow core body in the laminated state. A pillow main body is formed by being housed inside the exterior cloth in a state of being respectively applied, and a height adjusting portion is provided on the lower surface of the pillow main body, and the height adjusting portion is the pillow core. A plurality of flat plate-like height adjustment sheet materials having a length and width substantially the same as the body, and both sides in the width direction of the rectangle of the fabric excellent in elasticity are sewn to the lower surface of the exterior cloth. And an adjustment material containing bag for holding the height adjusting sheet material between the lower surface of the exterior cloth, and both end portions in the length direction of the adjustment material containing bag are folded back into a plurality of layers. The folded parts are sewn together to form a band shape in the width direction. The lid-shaped pieces are formed to extend, across the sides of the length direction of the lid-like piece is sewn to the lower surface of the outer fabric.

  According to the pillow according to claim 1, the three-dimensional structure cushion body arranged at the portion where the head is directly placed via the outer cloth is deformed by the load of the placed head and neck. Is received on the flattened upper surface of the three-dimensional structure network to disperse the deformation stress, and the deformation stress is received by the low repulsive force due to elasticity by absorbing the deformation stress by the energy conversion of the entire structure, In spite of being able to give a large subsidence to the load by the head, extreme local subsidence is prevented and the head and neck are elastically deformed so as to be supported by a soft touch gripping force. In addition, when the deformation stress due to the load on the head is released, the three-dimensional structure cushion body easily recovers to its original form due to the elasticity of the thermoplastic elastic resin. It has sex. Moreover, since the three-dimensional cushion body is a three-dimensional mesh body, it has excellent breathability, and also contains steam and heat accumulated inside when the three-dimensional cushion body is deformed into a compressed shape. Since it has a pumping function that discharges air and replaces it with fresh outside air when it is recovered from the compressed shape and has excellent heat dissipation, it is possible to obtain a comfortable sleeping comfort that is difficult to stuffy.

  Further, the soft sponge sheet interposed between the lower part of the three-dimensional structure cushion body and the upper surface of the pillow core body is elastically deformed corresponding to the deformation of the three-dimensional structure cushion body when the head is placed. Therefore, there is no feeling of the bottom of elasticity, and a better cushioning property can be secured. In addition, the soft sponge-like sheet body acts to hold the three-dimensional structure cushion body in the deformed state when elastically deformed, so that the stability of head and neck stability is further improved.

  Further, the pillow core body functions to prevent a large deformation from occurring and always maintain a predetermined pillow height stably over a long period of time. In addition, this pillow is a rectangular parallelepiped having a length of 500 to 700 mm, and has a uniform configuration in the length direction. Therefore, the pillow can be smoothly turned over without any restriction during sleep. In addition, the head and neck can be stably held at any place where the roll is over. In particular, the pillow core has a relatively long length that can be turned over to the left and right, and is formed of a plastic material that is a hard material that does not easily dent, but it is compared with 500 to 700 mm. Therefore, it can bend into a curved shape in response to the mattress sinking due to the load on the head, and the head is still held in a more natural state.

  According to the pillow according to claim 2, the upper surface of the soft sponge-like sheet material made of urethane foam having a thickness of 1/10 to 3/10 of the thickness of the pillow core is doubled with respect to the outer peripheral surface of the pillow core. Since it is wound around the covering state, the cushioning property when the head is placed is further improved, and the head can be stably held.

According to the pillow according to claim 3, in addition to obtaining the same effect as that of the invention according to claim 1, the inside of the storage bag is filled with a heat insulating material that is freely deformed, such as natural cotton. Since two heat retaining members are applied to both sides of the pillow core body, the soft sponge sheet material, and the three-dimensional structure cushion body, which are laminated in a rectangular parallelepiped shape as a whole, both the left and right directions along the rectangular parallelepiped shape You can turn over freely, and even if you turn over in any direction, the heat insulating material of the heat insulating member will surely come into contact with the shoulder and neck, so it is possible to effectively prevent cold shoulder and neck Can keep warm. Further, since the heat retaining members are disposed on both sides in the width direction, the directionality is lost when used, and either one of the heat retaining members can be reliably brought into contact with the neck and the shoulder.

  According to the pillow according to claim 4, the adjustment of the pillow height by the height adjusting portion is adjusted in a state where the lid-like piece formed on the adjusting material containing bag made of fabric having excellent stretchability is grasped and pulled out. Insert or pull out the required number of height adjustment sheet materials between the material storage bag and the exterior cloth, and then release the gripping of the lid-like piece. The entrance between the adjustment material accommodation bag and the exterior fabric is closed by the pulling force applied to both sides in the length direction as it is sewn to the lower surface of the fabric. For this reason, in this pillow, it is possible to easily adjust the pillow height as compared to the case of performing the pillow height adjustment with the opening and closing operation of the fastener as in the conventional pillow, and the adjustment material accommodation bag Since the entrance of the height adjusting portion can be closed by the lid-like piece formed by using a part of this, the appearance is good.

It is a perspective view which shows the pillow which concerns on one Embodiment of this invention. It is the sectional view on the AA line of FIG. It is the BB sectional view taken on the line of FIG. It is sectional drawing along the BB line of FIG. 1 at the time of supine. It is sectional drawing along the BB line of FIG. 1 at the time of lying down. (A)-(c) is a partial cross section figure along the AA line of FIG. 1 in the state which changed pillow height variously.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a pillow according to a first embodiment of the present invention. This pillow has a configuration in which a height adjusting portion 2 is provided on the lower surface of a pillow main body portion 1 that has a substantially rectangular parallelepiped appearance as a whole. It has become. The substantially rectangular parallelepiped pillow main body 1 has a length L of about 600 mm, a width W of about 270 mm, and a height H of about 60 mm. The length L of the pillow main body 1 is set to a length dimension that allows a sleeper in a supine posture with the back of the head in the center to easily lie down from side to side and take a lying posture easily. ing.

  2 and 3 show a cross-sectional view taken along line AA and a cross-sectional view taken along line BB in FIG. 1, respectively. The pillow main body 1 is covered with an exterior cloth 3 formed by sewing a 100% cotton cloth. That is, all the components of the pillow main body 1 are accommodated in the exterior cloth 3. The pillow core body 4 mounted below the pillow main body 1 is made of a lightweight material having plasticity that does not easily dent even when pressurized, such as a foaming resin. In this embodiment, the length is A flat plate shape of 600 mm, a width of 180 mm, and a thickness of 25 mm is formed in a rectangular parallelepiped. Although this pillow core body 4 is not recessed as described above, it has a relatively elongated rectangular planar shape having a length of 600 mm and a width of 180 mm, and has a relatively thin thickness of 25 mm. Can be bent into a curved shape corresponding to the load.

  A soft sponge-like sheet body 7 made of, for example, urethane foam or the like is wound around the entire outer peripheral surface of the pillow core body 4 about a half turn. In this embodiment, the soft sponge-like sheet body 7 is set in a shape having a length direction of 630 mm, a width direction of 670 mm, and a thickness of 5 mm. The soft sponge-like sheet body 7 is wound in such a manner that the upper surface and both side surfaces of the pillow core body 4 are overlapped and the lower surface of the pillow core body 4 is covered by a single layer. That is, the soft sponge-like sheet body 7 is provided so as to cover at least the top surface of the pillow core body 4 with a double overlap by using a material having a thickness of 1/5 with respect to the thickness of the pillow core body 4.

  On the upper surface of the pillow core body 4, a three-dimensional structure cushion body 8 is disposed so as to interpose a double-stacked soft sponge sheet body 7. This three-dimensional structure cushion body 8 is made by imitating fibers of natural puncture by connecting most of the contact portions of random loops formed by winding continuous filaments made of thermoplastic elastic resin to each other. Formed into a rectangular parallelepiped having an outer shape substantially the same as the outer shape of the pillow core body 4 including the soft sponge-like sheet body 7 formed on the outer peripheral surface and formed into a reticular structure having a three-dimensional structure. It has become. This three-dimensional structure cushion body 8 is deformed as a whole when receiving deformation stress from the outside, and receives deformation stress by energy conversion, so that extreme local subduction does not occur, and the deformation stress is released. Then, it has a function of easily recovering to its original form due to its own elasticity. Further, since the three-dimensional structure cushion body 8 is formed as a three-dimensional network, the air permeability is remarkably good.

  Two heat retaining members 9 and 9 are respectively applied to the soft sponge-like sheet body 7 and the three-dimensional structure cushion body 8 on both sides of the pillow core body 4 and the three-dimensional structure cushion body 8 covered with the soft sponge-like sheet body 7. It is provided by arrangement. The heat insulating member 9 is formed by inserting a heat insulating material 11 such as natural cotton, bread, or cotton into a filled state in a cylindrical 100% cotton storage bag 10 having a diameter of about 60 mm and a length of about 600 mm. It is a thing. The heat retaining member 9 is deformed into a shape applied to the soft sponge-like sheet body 7 and the three-dimensional structure cushion body 8 by being sandwiched between the outer cloth 3 and the soft sponge-like sheet body 7 and the three-dimensional structure cushion body 8. To do. A grip piece 1a is formed on both ends of the outer cloth 3 in the length direction (left and right direction in FIG. 2) by sewing in a state where the two pieces overlap each other, and the grip piece 1a is used for carrying a pillow. Sometimes used.

  The height adjusting unit 2 accommodates the height adjusting sheet material 13 between the outer fabric 3 by sewing both sides in the width direction of a fabric excellent in elasticity, for example, a knit fabric, to the lower surface of the outer fabric 3. The adjusting material accommodation bag 12 and the height adjusting sheet material 13 accommodated in the adjusting material accommodation bag 12 by an arbitrarily selected number of sheets are constituted. As the height adjustment sheet material 13, for example, a polyethylene sheet having a thickness of 5 mm can be suitably used. In FIG. 2, for the sake of convenience of illustration, the adjustment material containing bag 12 is illustrated in a case where both end portions in the length direction (left and right direction in FIG. 2) are folded in half. Thus, both ends are folded twice, and the three-layered fabric in the second folded portion 12a and the two-layered fabric in the first folded portion 12c are sewn together. The sewn portion is indicated by a cross. As a result, a lid-like piece 12b is formed on the inner side of the first folded portion 12a. The lid-like piece 12b is sewn to the outer cloth 3 so that both ends in the belt-like length direction (left and right direction in FIG. 3) are sewn in FIG. 6 (a). Yes. As described above, the height adjustment unit 2 accommodates the adjustment material in a state where the lid-shaped piece 12b integrally formed using a part of the adjustment material accommodation bag 12 made of fabric having excellent stretchability is grasped and pulled out. If the required number of height adjusting sheet members 13 are inserted or pulled out between the bag 12 and the outer cloth 3, and then the cover-like piece 12b is released from the grip, the cover-like piece 12b has both ends in the belt-like length direction. The entrance between the accommodation bag 12 and the exterior cloth 3 is kept closed by the pulling force applied to both sides in the length direction as the sides are sewn to the lower surface of the exterior cloth 3. Is done. For this reason, in this pillow, it is possible to easily adjust the pillow height as compared to the case of performing the pillow height adjustment with the opening and closing operation of the fastener as in the conventional pillow, and the adjustment material accommodation bag Since the entrance of the height adjusting portion 2 can be closed by the lid-shaped piece 12b formed by using a part of the cover 12 in a state of concealing the internal height adjusting sheet material 13, the appearance is good. Become.

Next, functions of the pillow according to the embodiment will be described. In this pillow, a three-dimensional structure cushion body 8 is arranged at a portion where the head is directly placed via the exterior cloth 3, and the three-dimensional structure cushion body 8 is made of natural hemp fibers as described above. As a result, the deformation stress due to the load of the head to be placed is received on the flattened upper surface of the mesh body to disperse the deformation stress, and the entire structure is Since the deformation stress is absorbed by the deformed energy conversion and the deformation stress is received with a low repulsive force due to elasticity, as shown in FIG. 4 and FIG. Extreme local sinking is prevented, and the head and neck are elastically deformed to support with a soft touch gripping force.

  Further, the three-dimensional structure cushion body 8 is easily restored to its original form by the elasticity of the thermoplastic elastic resin when the deformation stress due to the load on the head is released, so that the same shape can always be maintained for a long time. It has high sag resistance. In addition, the three-dimensional structure cushion body 8 has a high porosity, extremely good air permeability as the air hole diameter is remarkably large, and further contains steam and heat accumulated inside when deformed into a compressed shape. Since it has a pump function that exhausts air and replaces the inside with fresh outside air when recovered from the compressed shape, it has excellent heat dissipation as well as breathability, and it is comfortable to sleep and comfortable to sleep can get.

  Further, a two-layered soft sponge-like sheet body 7 is interposed between the lower part of the three-dimensional structure cushion body 8 and the upper surface of the pillow core body 4, and the head of the soft sponge-like sheet body 7 is placed. When it is done, it is elastically deformed corresponding to the deformation of the three-dimensional structure cushion body 8, so that there is no feeling of the bottom of the elasticity, and a better cushioning property can be secured. Moreover, since the soft sponge-like sheet body 7 acts to hold the three-dimensional structure cushion body 8 in an elastically deformed state, the stability of the head and neck is further improved.

  The pillow core body 4 arranged at the lower part of the pillow body 1 is prevented from being greatly deformed in the pillow body 1 by a large load, and always maintains a predetermined pillow height stably over a long period of time. To work. On the other hand, this pillow is set to a relatively long dimension that allows a sleeper in a supine posture with the back of the head in the center to take a lying posture by turning over naturally from its state to the left and right, respectively, Since the upper surface on which the head is placed is formed in a uniform flat surface, it is possible to turn over freely without any restriction during sleep. Moreover, since the pillow core body 4 has a relatively long length that can be turned over to the left and right freely, the mattress sinks due to the load of the human body even though it is a hard material that does not easily dent. Correspondingly, it can be bent into a curved shape, and the head is held in a more natural state.

  In addition, as clearly shown in FIG. 4, the heat retaining member 9 arranged in the length direction on both sides in the width direction has the head placed above the three-dimensional cushion body 8 of the pillow body 1. Since the neck and shoulders are deformed so as to fit into the neck and shoulders, the shoulder and the shoulder can be prevented from being cooled by air flowing in through a gap that can easily be made in the shoulder opening during sleep. The part can be kept warm. Moreover, as shown in FIG. 5, when the pillow is turned over to the lying position, the entire pillow body 1 is a rectangular parallelepiped, so that the heat retaining member 9 fits to the neck and shoulders. It touches the neck and shoulder while deforming.

  Furthermore, in this pillow, the height adjustment unit 2 can be adjusted to a pillow height suitable for the pillow user by selecting the number of the very thin height adjustment sheet members 13. Unlike conventional height adjustment structures provided with fasteners, Velcro fasteners, etc., the required number of height adjustment sheet materials 13 can be adjusted by simply expanding / contracting the adjustment material containing bag 12 made of knit fabric having excellent elasticity. The inside height adjustment sheet material 13 is concealed by the band-like lid-like pieces 12b that can be accommodated in the accommodation bag 12 and are formed by using a part of both sides in the length direction of the adjustment material accommodation bag 12. In addition, the opening of the adjustment material accommodation bag 12 can be closed so that the height adjustment sheet material 13 does not fall off from the adjustment material accommodation bag 12, so that the appearance is good.

  As shown in FIG. 6A, when no height adjusting sheet material 13 is accommodated, the adjusting material accommodating bag portion 12 having excellent stretchability is merely overlaid on the lower surface of the outer cloth 3. There is no problem. FIG. 6B shows a state in which three height adjusting sheet members 13 are accommodated, and FIG. 6C shows a state in which five height adjusting sheet members 13 are accommodated. Regardless of the number of stored height adjusting sheet members 13, the height adjusting unit 2 has an elastic lid-like piece 12 b composed of the adjusting material storing bag unit 12 and the exterior cloth 3. The height adjusting sheet material 13 housed inside is held so as not to drop off.

  The present invention is not limited to the contents shown in the above embodiment, and various additions, modifications, or deletions are possible within the scope not departing from the gist of the present invention. It is included within the scope of the present invention.

  The pillow of the present invention can be used not only in general homes but also suitably as a dedicated pillow for performing orthodontic treatment in an osteopathic clinic or an orthopedic clinic.
