  In the pillow described in Patent Document 1, the height of the cervical vertebra support portion is higher than the height of the head support portion, and the cervical vertebra is supported by the cervical vertebra support portion, thereby relieving pressure on the larynx. It is possible to secure a good airway. However, no consideration is given to the user's turning over, leaving room for improvement. Moreover, in the pillow described in the said patent document 2, in order to respond to a user's turning, a pair of temporal part corresponding | compatible part is provided in the both sides of the head support part and the cervical vertebra support part, It is possible to cope with a suitable turn over. However, in the pillow described in Patent Document 2, the fillings filled in the head support part, the cervical spine support part, and the temporal part corresponding part are of the same type. For this reason, when a soft filling is used, the head and cervical vertebra cannot be properly supported, and when a hard filling is used, there is a possibility that comfortable sleep cannot be secured, leaving room for improvement. ing. Moreover, in the pillow described in the above-mentioned Patent Document 3, a portion harder than the filling filled in the head support portion is filled in the temporal portion corresponding portion, and the head when turning over can be suitably supported. It has become. However, there is a possibility that comfortable sleeping cannot be ensured by touching a hard filling on the temporal region when turning over, leaving room for improvement.

  As described above, there is a lot of room for improvement in the pillow whose interior is partitioned into a plurality of portions, and it is possible to improve the practicality of the pillow by making various improvements. This invention is made | formed in view of such a situation, and makes it a subject to provide a highly practical pillow.

In order to solve the above problems, the pillow of the present invention is located at both ends in the width direction, and has a density (JIS K7222) of 34 to 38 kg / m ³ , a hardness (JIS K6400-2) of 127 to 167N, and a resilience resilience. (JIS K6400-3) A pair of high resilience elastic portions having a high resilience urethane tip that is 40% or more and in which urethane foam is pulverized to a size of 3 to 30 mm, and the pair of high resilience portions A cervical vertebra support portion, which is located between the elastic portions and supports the user's cervical vertebrae, and is filled with hollow cylindrical polypropylene or polyethylene beads having a diameter of 3 to 6 mm and a length of 5 to 10 mm; located between the high resilience of the pair, to support the user's head, the density ^{(JIS K7222) 20~40kg / m 3} , the number of cells (JIS K6400-1) 22~28 / 25 mm urethane foam pulverized to a size of 3 to 40 mm, and a head support portion filled with a highly ventilated urethane tip, and the height of the pair of high resilience elastic portions is the cervical spine support The height of the head support part is higher than the height of the cervical vertebra support part.

In the pillow of the present invention, the height of the head support portion is set lower than the height of the cervical spine support portion. Thereby, it becomes possible to relieve pressure on the larynx and secure a good airway. Further, the height of the high resilience elastic part is higher than the heights of the cervical spine support part and the head support part. As a result, it is possible to suitably cope with the user turning over. The cervical spine support portion is filled with hollow cylindrical polypropylene or polyethylene beads having a diameter of 3 to 6 mm and a length of 5 to 10 mm, and the head support portion has a relatively highly breathable urethane foam, Specifically, a urethane foam having a density (JIS K7222) of 20 to 40 kg / m ³ and a number of cells (JIS K6400-1) of 22 to 28 pieces / 25 mm is filled. Thereby, it becomes possible to improve the air permeability of the place which supports a head and a cervical spine for a long time at the time of sleep. In particular, as a filling to the head support portion, a pulverized urethane foam that has high air permeability and is difficult to heat up can be used to ensure the coolness of the head. In addition, a hollow cylindrical polypropylene or polyethylene bead is used for filling the cervical spine support, and the entire cervical spine can be held securely by moving the beads according to the shape of the neck. Become. Furthermore, by using polypropylene or polyethylene beads that can be easily taken out from the inside of the pillow, the height of the cervical vertebra support portion can be easily adjusted. Moreover, as a filling to the high resilience elastic part which the temporal region touches when turning over, urethane foam with low hardness and high resilience elasticity, specifically, density (JIS K7222) 34 to 38 kg / m ³ , hardness (JIS) K6400-2) 127 to 167N, impact resilience (JIS K6400-3) 40% or more of pulverized urethane foam is used. For this reason, when turning over, the temporal region comes into contact with a soft and elastic member, and it is possible to ensure a comfortable sleep when turning over. Therefore, according to the pillow of the present invention, it is possible to make various improvements as described above, and it is possible to provide a highly practical pillow.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as modes for carrying out the present invention.

  FIG. 1 shows a pillow 10 according to an embodiment of the present invention. The pillow 10 includes a front cloth 12 having a generally rectangular bag shape, and the inside of the front cloth 12 is divided into four parts. Each of these four compartments is filled with filling, and the four parts filled with these fillings support the user's cervical vertebrae and head, and support the temporal region when the user rolls over. It is possible to support. Hereinafter, the structure of the pillow 10 will be described in detail with reference to FIG. 2 showing the pillow 10 from a viewpoint from above and FIGS. 3 to 5 which are cross-sectional views of FIG. In this specification, the horizontal direction in FIG. 2 is referred to as the width direction, the vertical direction in FIG. 2 is referred to as the depth direction, and the direction perpendicular to the width direction and the depth direction is referred to as the height direction.

  As shown in FIG. 2, the pillow 10 is divided into four parts by three partition cloths 14, 16, and 18 sewn inside the front cloth 12. Specifically, two of the three partition cloths 14, 16, 18 (hereinafter referred to as “depth direction partition cloth”) 14, 16 are distinguished from the remaining one partition cloth. The inside of the front cloth 12 is sewn so as to extend in the depth direction, and the inside of the front cloth 12 is roughly divided into three equal parts in the width direction. As shown in FIG. 3 which is a cross-sectional view taken along line AA shown in FIG. 2 and FIG. 4 which is a cross-sectional view taken along line BB shown in FIG. And is sewn to the lower surface of the front cloth 12 at the lower edge. Thus, the pair of temporal head corresponding portions 20 and 22 are partitioned by the two depth direction partitioning cloths 14 and 16 and the both ends of the front cloth 12 in the width direction.

  The part between the pair of side head corresponding parts 20 and 22 is another partition cloth (hereinafter referred to as “width direction partition cloth” in order to distinguish from the two depth direction partition cloths 14 and 16). 18 is divided into two parts. The width direction partition cloth 18 is sewn inside the front cloth 12 so as to extend in the width direction, and is attached to the two depth direction partition cloths 14 and 16 at both ends. As shown in FIG. 5, which is a cross-sectional view taken along the CC line shown in FIG. 2, the width direction partition cloth 18 is also attached to the upper surface of the front cloth 12 at the upper edge and is attached to the lower surface of the front cloth 12 at the lower edge. . Incidentally, one edge 24 in the depth direction of the top cloth 12 has a shape recessed toward the other edge 26, and in order to distinguish the respective edges 24, 26, one edge 24 in the depth direction will be hereinafter described. Is called the curved edge 24, and the other edge 26 is called the non-curved edge 26. The head support portion 28 is partitioned by the non-curved edge 26, the width direction partition cloth 18, and the two depth direction partition cloths 14, 16, and the curved edge 24, the width direction partition cloth 18, and the two depths. The cervical vertebra support part 30 is partitioned by the direction partition cloths 14 and 16.

An openable / closable fastener 32 is attached to the non-curved edge 26 of the front cloth 12, and the head support portion 28 is filled with a large number of highly ventilated urethane chips 34 with good air permeability through the fastener 32. ing. The highly ventilated urethane tip 34 is obtained by pulverizing urethane foam from which a cell membrane having a density of 30 kg / m ³ and a cell number of 24 to 26 cells / 25 mm is removed, and has a size of 3 to 40 mm. Incidentally, the density is a value measured according to a method based on JIS K7222: 2004, and the number of cells is a value measured based on a method based on JIS K6400-1: 2004 appendix 1. is there.

Further, an openable / closable fastener 36 is attached to the curved edge 24 of the front cloth 12, and a large number of polypropylene or polyethylene beads 38 having a hollow cylindrical shape are attached to the cervical spine support portion 30 via the fastener 36. Filled. Polypropylene or polyethylene beads 38 is the size of the diameter of 4 mm, length 8 mm, as shown in FIG. 5, the height H ₁ of the cervical support portion 30, the height H ₂ of the head support 28 The cervical support 30 is filled with polypropylene or polyethylene beads 38 so as to be higher.

Moreover, the fasteners 40 and 42 which can be opened and closed are attached to the both ends in the width direction of the surface cloth 12, and the side head corresponding | compatible part 20 as a high resilience elastic part through each fastener 40 and 42, Each of 22 is filled with a number of high resilience urethane tips 44 having high resilience resilience. The high resilience urethane tip 44 is obtained by pulverizing a urethane foam having a density of 35 kg / m ³ , a hardness of 147 N, and a resilience of 40% or more, and has a size of 3 to 30 mm. As shown in FIG. 4, each of the pair of temporal correspondence parts 20 and 22 has a height H _{3 of} each temporal correspondence part 20 and 22 higher than the height H ₁ of the cervical spine support part 30. As shown, the high resilience urethane tip 44 is filled. Incidentally, the density is a value measured according to a method based on JIS K7222: 2004, and the hardness is a value measured based on a method based on JIS K6400-2: 2004 D method. . Furthermore, the said impact resilience is the value measured based on the method based on JISK6400-3: 2011.

  With the structure described above, the pillow 10 supports the user's head by the head support portion 28 filled with the highly ventilated urethane tip 34 and supports the cervical spine filled with polypropylene or polyethylene beads 38. The portion 30 is configured to support the user's cervical spine. Thereby, it becomes possible to improve the air permeability of the place which supports a head and a cervical spine for a long time at the time of sleep. In particular, the head support portion 28 is filled with a highly ventilated urethane chip 34 having a relatively large cell, so that the air permeability of the head support portion 28 is increased and the head support portion 28 is not easily heated. It is possible to ensure the coolness of the head. Conventionally, “head cold foot fever” is considered to be one of the factors of comfortable sleep, and it is also considered that blood circulation is improved by ensuring the coolness of the head. Therefore, according to this pillow 10, while ensuring a comfortable sleep and improving blood circulation, it is possible to improve health and, in other words, have a positive effect on cosmetics. Moreover, since it has elasticity compared with a bead made from polypropylene or polyethylene by using a highly ventilated urethane tip at the head placement location, it can be easily turned over.

Further, the height H ₂ of the head support portion 28 of the pillow 10 is set lower than the height H ₁ of the cervical vertebra support portion 30. Thereby, it becomes possible to relieve | stress the user's laryngeal pressure at the time of sleep, and to ensure a favorable airway. Furthermore, the cervical vertebra is lifted upward by the cervical vertebra support part 30, so that the skin from the user's jaw to the neck has a certain degree of elasticity. On the other hand, for example, when the head is lifted upward, the jaw and the neck approach each other, and wrinkles are likely to occur on the skin from the user's jaw to the neck. That is, according to this pillow 10, it is possible to maintain the skin from the user's chin to the neck to a certain degree of elasticity during a relatively long sleeping time, and to prevent wrinkles at that site. It becomes. In particular, the cervical vertebra support portion 30 that supports the cervical vertebra is filled with polypropylene or polyethylene beads 38 that move to some extent, so that the entire cervical vertebra can be reliably supported according to the shape of the cervical vertebra. Thus, it is possible to effectively secure the airway and prevent sputum. Furthermore, since the polypropylene or polyethylene beads 38 can be easily taken out from the cervical spine support portion 30, the height of the cervical spine support portion 30 can be easily adjusted, and can be used for people of various body shapes. It is possible.

Further, the height H ₃ of the temporal head corresponding portions 20, 22 of the pillow 10 is higher than the height H ₁ of the cervical vertebra support portion 30. That is, the height H ₃ of the temporal head corresponding parts 20 and 22 is set higher than the height of the other part of the pillow 10. As a result, when the user rolls over, the temporal region can be supported by the temporal portion corresponding parts 20 and 22, and it is possible to suitably cope with the roll over. In particular, the side head corresponding portions 20 and 22 that the side heads touch when turning over are filled with urethane chips 44 having low hardness and high resilience. For this reason, at the time of turning over, the temporal region comes into contact with a soft and elastic portion, and it is possible to ensure a comfortable sleep when turning over.

  Incidentally, a pair of non-biased fabrics 50 and 52 are sewn on the upper surface of the top fabric 12 at the upper edge and sewn on the lower surface of the top fabric 12 at the lower edge. Yes. Thereby, it is possible to prevent the bias of the highly ventilated urethane tip 34 in the head support portion 28. A pair of annular ribbons 54 and 56 are attached to the non-curved edge 26 of the front cloth 12. As a result, the pillow 10 can be easily dried on a clothesline or the like.

  Further, a pillow cover 60 is prepared for the pillow 10 as shown in FIG. A fastener 62 extending in the width direction is attached to the entire back surface of the pillow cover 60, and the pillow cover 60 can be attached to and detached from the pillow 10 via the fastener 62. The surface of the pillow cover 60 is constituted by a pair of side portions 64 and 66 located at both ends in the width direction and a central portion 68 located between the pair of side portions 64 and 66. Each of the pair of side portions 64 and 66 is made of a material that is soft to the touch, and can ensure a comfortable sleep when turning over. In addition, the central portion 68 has good air permeability and is formed of a material having a certain thickness, so that the air permeability of the head and cervical vertebrae can be secured and the touch feeling of polypropylene or polyethylene beads 38 can be softened. It has become.

  In addition, this invention is not limited to the said Example, It can implement in the various aspect which gave various change and improvement based on the knowledge of those skilled in the art. For example, a pad insertion part that can attach and detach a pad is provided on the surface of the cervical vertebra support part 30 opposite to the surface that supports the cervical vertebra of the user, and the height of the part that supports the cervical vertebra is adjusted by attaching and detaching the pad. It can be configured to do so. FIG. 7 shows a modified example of the pillow 70 thus configured. The pillow 70 of this modified example has substantially the same configuration as the pillow 10 of the above-described embodiment except for the pad insertion portion 72. Therefore, the description will focus on the pad insertion portion 72, and the same components are denoted by the same reference numerals. The explanation will be omitted or simplified. FIG. 7 is a perspective view showing a surface opposite to the surface on which the user of the pillow 70 puts the head and cervical vertebrae, that is, the back surface of the pillow 70.

  On the back surface of the cervical vertebra support portion 30 of the pillow 70, a partition cloth 74 that divides the pad insertion portion 72 together with the back surface is sewn. Specifically, the partition cloth 74 has a rectangular shape that is substantially the same shape as the cervical vertebra support portion 30, and one of the pair of long sides is sewn at the boundary between the cervical vertebra support portion 30 and the head support portion 28. In addition, each of the pair of short sides is sewn to the boundary between the cervical spine support portion 30 and each of the pair of side corresponding portions 20 and 22. Thereby, the pad insertion part 72 is partitioned by the cervical vertebra support part 30 and the partition cloth 74 in a state where the other side of the pair of long sides of the partition cloth 74 is opened.

  By inserting the pad 76 into the pad insertion portion 72, it becomes possible to increase the height of the portion that supports the user's cervical vertebra. On the other hand, by removing the pad 76 from the pad insertion portion 72, the user can It is possible to reduce the height of the portion supporting the cervical spine. In addition, a plurality of pads 76 can be inserted into the pad insertion portion 72, and the height can be adjusted relatively freely according to the user's preference.

  This pad 76 is made by embedding a synthetic resin fiber cotton (for example, polyester cotton) in a double raschel knitted cloth bag made of polyester and sewing the outer periphery of the cloth bag. The dimensions of the pad 76 are 150 mm × 115 mm. × 10 mm (length in the width direction × length in the depth direction × height).

  Further, the cervical spine support portion 30 is filled with a polypropylene or polyethylene bead 38, or a bead filling port 80 for taking out the polypropylene or polyethylene bead 38 from the cervical spine support portion 30 is covered with a partition cloth 74. It is formed in the part 30. That is, in a state where the pad 76 is inserted into the pad insertion part 72, the bead filling port 80 is located between the pad 76 and the cervical spine support part 30, and the pad 76 is removed from the pad insertion part 72, By turning up the cloth 74, the bead filling port 80 can be confirmed.

  The bead filling port 80 includes a first fastener 82 attached to the cervical vertebra support portion 30 covered with the partition cloth 74 so as to be openable and closable, a cylindrical inner bag 84, and one of the cylindrical inner bags 84 opened. The other end of the cylindrical inner bag 84 is sewn so as to be openable and closable along the edge of the first fastener 82. .

  In the bead filling port 80 having such a structure, the inner bag 84 is housed inside the cervical vertebra support part 30 when the pillow is used, and the first fastener 82 and the second fastener 86 are closed. Accordingly, the polypropylene or polyethylene beads 38 filled in the cervical spine support portion 30 are hardly spilled out of the pillow by the two fasteners 82 and 84. Moreover, since the 1st fastener 82 is attached to the cervical vertebra support part 30 covered with the division cloth 74, there is almost no possibility that the 1st fastener 82 will be caught in something and open unexpectedly.

  On the other hand, when filling the cervical spine support portion 30 with polypropylene or polyethylene beads 38, or when taking out the polypropylene or polyethylene beads 38 from the cervical spine support portion 30, the first fastener 82 is opened and the inner bag 84 is opened. Is pulled out from the cervical spine support 30 while being inverted. Then, the second fastener 86 exposed to the outside is opened, and polypropylene or polyethylene beads 38 are filled or taken out through the opened second fastener 86. 7 shows the pillow 70 in a state where the inner bag 84 is pulled out from the cervical vertebra support portion 30, and FIG. 8 is a perspective view of the pillow 70 in which the second fastener 86 is opened in this state. I will show you.

Further, for example, in the pillow 10 of the above embodiment, the length X ₁ in the depth direction of the head support portion 28 is 150 mm, and the length X ₂ in the depth direction of the cervical vertebra support portion 30 is 100 mm. Furthermore, the width direction of the length _{W 1} of the head support 28 and the cervical vertebrae support portion 30 is a 170 mm, a width direction length _{W 2} of each of the pair of side head corresponding portions 20, 22 is a 130mm ing. Each dimension can be changed to provide a pillow larger than this pillow 10 or a smaller pillow. Specifically, for example, in the depth direction of the head support 28 the length _{X 1} and 240 mm, the depth direction of the cervical spine support portion 30 of the length _{X 2} with a 110 mm, head support 28 and the cervical support in the width direction of the part 30 the length _{W 1} and 180 mm, 1 pair of each of the width direction of the temporal counterpart 20, 22 the length _{W 2} may be 200 mm. Incidentally, in the pillow 10, the height _{H 1} of the cervical support portion 30 is a 60 mm, height _{H 2} of the head support 28 is a 40 mm, 1 each pair of temporal counterpart 20, 22 of the height H ₃ which is a 75 mm, of course, these dimensions may also be varied. However, in order to avoid the height of the cervical support 30 being too high or the difference between the height of the head support 28 and the height of the cervical support 30 being too large, the height of the pillow may not be changed greatly. desirable.
