JP, 2017-29247, A

The pillow described above is provided with a plurality of partition portions that partition the inner space of the pillow, and each of the plurality of partition portions extends in the longitudinal direction of the pillow or the width direction of the pillow. By the way, a user who uses a pillow often moves his/her head in an arc shape around the neck when rolling over the pillow. That is, when the user turns over, the head of the user moves along an arcuate trajectory centered on the neck of the user.

Therefore, when the partition portion extends in the longitudinal direction of the pillow or the width direction of the pillow as in the above-mentioned pillow, the direction in which the partition portion extends largely deviates from the locus of movement of the arcuate head and neck. Therefore, the head and the neck often cross the partition when turning over. Further, the partition part often has a cloth called a gusset built therein and is often harder than other parts. Therefore, since the head and neck frequently cross the hard partition when turning over, there is a problem that the head and neck are pressed frequently when turning over. Therefore, there is room for improvement in the ease of turning over at bedtime.

An object of the present disclosure is to provide a pillow that can facilitate turning over at bedtime.

A pillow according to the present disclosure includes a side ground that is a rectangular parallelepiped having a pair of long sides extending in the first direction and a pair of short sides extending in the second direction that intersects the first direction. A pillow in which the contents are stored in the inner space of the inside of, and a plurality of partition parts for partitioning the inner space are provided, and the plurality of partition parts are one short side of the pair of short sides to the other short side. A first partition part extending to the first partition part, and a pair of second partition parts extending from the first partition part to the first long side which is one of the pair of long sides and arranged in the first direction. The first partition part is curved toward the center of the side ground in the second direction as it goes toward the center of the side ground in the first direction, and each of the pair of second partition parts includes the first partition part. Inclining diagonally toward both ends of the lateral ground in the first direction as the distance from the vehicle increases.

This pillow includes a rectangular parallelepiped side ground having a pair of long sides extending in the first direction and a pair of short sides extending in the second direction, and the contents are stored in the internal space of the side ground. In addition, this pillow includes a plurality of partition parts that partition the internal space of the pillow. The plurality of partition portions include a first partition portion that extends in the first direction from one of the pair of short sides to the other, and a pair of first partition portions that extends from the first partition portion toward the first long side and that are arranged along the first direction. Includes 2 partitions. And the 1st partition part is curved toward the center side of the 2nd direction as it goes to the center of the 1st direction, and each 2nd partition part inclines toward both ends of the 1st direction as it separates from the 1st partition part. There is. Therefore, when the user's head is placed on the first long side of the first partition and the user's neck is placed on the side opposite to the first long side of the first partition, when rolling over Moreover, the user's head and neck move in an arc along the curved first partition. That is, the first partition section is provided along the movement trajectory of the head and neck. As a result, the frequency of the head and neck crossing the hard first partition when turning over is reduced, and the head and neck move along the first partition, so that pressure on the head and neck is suppressed and at bedtime. You can make it easier to roll over. Moreover, each 2nd partition part inclines to the both ends in the 1st direction as it separates from the 1st partition part. Therefore, since each of the second partition portions is inclined toward both end sides in the first direction as the second partition portions are separated from the first partition portion, the frequency of the user's head and neck crossing the second partition portion when turning over is reduced. be able to. Therefore, it is possible to make it difficult for the second partition part having a hard head and neck to cross the second partition part, and thus it is possible to improve the rolling property.

The internal space includes a pair of first internal spaces located at both ends of the pair of second partition parts in the first direction, and a second internal space located between the pair of first internal spaces. The contents may include a flexible material housed in each of the first internal spaces and a sheet material that is in contact with the back side of the surface of the side material in the second internal space and is harder than the flexible material. In this case, when the head of the user is placed between the pair of second partition portions, the head comes into contact with the sheet material that is harder than the flexible material through the side ground. Therefore, when the head comes into contact with the hard sheet material via the side ground, it is possible to prevent the head from sinking and smoothly turn over. Further, the flexible material is housed in each of the first internal spaces located on both ends of each of the second partition portions in the first direction. Therefore, when the user hits over and the head reaches the second partition, the user's cheek is placed on the upper portion of the flexible material. Therefore, the cheeks of the user who has reached the second partition and laid sideways can be sunk into the flexible material. Therefore, it is possible to reduce pressure on the cheeks when the person is lying sideways, and to prevent the head from falling off the pillow when lying sideways.

The sheet material may include a mesh material that contacts the back side of the surface of the side material. In this case, when the user's head is placed between the pair of second partition parts, the head comes into contact with the mesh material via the side ground. Therefore, the air permeability of the region where the head is placed can be enhanced. Therefore, it is possible to prevent heat and moisture from staying in the head and to prevent stuffiness of the head, thereby making it possible to improve the user's comfort in sleeping.

The internal space includes a lower side of the pair of first internal spaces and a third internal space located below the second internal space, and the content includes a granular body accommodated in the third internal space. But it's okay. In this case, the granular material is housed in the third internal space located below the first internal space and the second internal space. Therefore, the head of the user placed above the pair of the first internal space or the second internal space can be firmly supported by the granular body.

According to the present invention, it is possible to easily turn over at bedtime.

In addition, in order to facilitate understanding, some of the drawings may be simplified or exaggerated, and dimensional ratios and the like are not limited to those illustrated in the drawings.

As shown in FIGS. 1 and 2, the pillow 1 according to the present embodiment includes a side material 10. The contents 20 are accommodated in the internal space S (see FIG. 6 or FIG. 7) of the side ground 10, and the pillow 1 includes a plurality of partition portions 30 that partition the internal space S. The side ground 10 has a rectangular parallelepiped shape (rectangular shape in a plan view) as a whole, and has high flexibility.

In the present embodiment, the side ground 10 is quilted. As described above, the quilting of the side ground 10 enhances the heat retention of the side ground 10 and the design. The pillow 1 is, for example, a pillow body used in a state of being housed in a pillow cover for preventing dirt. As an example, the pillow 1 is used by being placed on a bedding such as a mattress or a bedding.

The pillow 1 has a pair of long sides 2 extending in the first direction D1 and a pair of short sides 3 extending in the second direction D2 intersecting the first direction D1. The first direction D1 is the longitudinal direction of the pillow 1, and the second direction D2 is the width direction of the pillow 1. For example, the first direction D1 and the second direction D2 are orthogonal to each other. The long side 2 includes a first long side 2b located on one side of the second direction D2 and a second long side 2c located on the other side of the second direction D2. The short side 3 includes a first short side 3b located on one side (left side in FIG. 1) of the first direction D1 and a second short side 3c located on the other side of the first direction D1.

For example, the first long side 2b extends linearly along the first direction D1, and the second long side 2c curves toward the center of the second direction D2 as it goes to the center of the first direction D1. The second long side 2c is provided with a recessed portion 2d that is recessed toward the center side in the second direction D2 at the center portion in the first direction D1, and the recessed portion 2d is gently curved and curved. The second long side 2c is, for example, a portion on which the neck M1 of the user M (see FIG. 5) is placed. The second long side 2c has a recess 2d so that the neck M1 can be easily placed on the second long side 2c.

Each of the first short side 3b and the second short side 3c extends, for example, in a straight line in the second direction D2, and a string-shaped reinforcing portion 3d (see FIG. And a bold portion in FIG. 2). The surface 10b of the side ground 10 has a symmetrical shape with respect to a central axis L1 that extends through the center O1 of the surface 10b in the second direction D2. Further, the back surface 10c of the side ground 10 has a symmetrical shape with respect to a central axis L2 that extends through the center O2 of the back surface 10c in the second direction D2.

For example, the length of the side ground 10 in the first direction D1 is 40 cm or more and 90 cm or less, may be 50 cm or more and 80 cm or less, or may be 60 cm or more and 70 cm or less, and is 63 cm as an example. is there. The length of the side ground 10 in the second direction D2 is 20 cm or more and 70 cm or less, may be 30 cm or more and 60 cm or less, or may be 40 cm or more and 50 cm or less, and is 43 cm as an example. However, these lengths can be appropriately changed. The material of the side material 10 may be, for example, polyester or may include cardboard knit (multi-layer structure knitted material). In this case, it is possible to improve the heat retention and durability of the side material 10 and improve the comfort of use.

The partition 30 includes a first partition 31 extending from the first short side 3b to the second short side 3c and a pair of first partition 31 extending from the first partition 31 to the first long side 2b and arranged in the first direction D1. 2 partition parts 32 are included. For example, the first long side 2b side of the first partition portion 31 is a portion on which the head M2 of the user M (see FIG. 5) is placed, and the both end sides of the pair of second partition portions 32 in the first direction D1 are disposed. This is a part on which the cheek M3 of the user M when lying sideways is placed. For example, the second long side 2c side of the first partition portion 31 is a portion on which the neck M1 of the user M is placed.

As an example, in a state where no external force is applied, both end sides of the pair of second partition portions 32 in the first direction D1 (portions on which the cheeks M3 are placed) are on the second long side 2c side of the first partition portion 31 ( It is more raised (bulging) than the part where the neck M1 is placed). The second long side 2c side of the first partition portion 31 (the portion on which the neck M1 is placed) is higher than the portion between the pair of second partition portions 32 (the portion on which the head portion M2 is placed) (bulging up). Exist).

In this way, since both ends of the pair of second partition portions 32 in the first direction D1 are raised, the head M2 and the cheek bones of the user M when lying sideways can be wrapped gently and the head M2 It is possible to prevent the pillow 1 from falling off. Moreover, since the second long side 2c side of the first partition portion 31 is raised, the neck M1 through which a complicated tissue such as a nerve passes can be protected more reliably. Furthermore, since the part between the pair of second partition portions 32 is not raised, the sinking of the head M2 can be suppressed and the person can smoothly turn over.

The first partition 31 extends, for example, from the front surface 10b to the back surface 10c in the internal space S of the side ground 10, and for example, the entire side ground 10 is provided on one side in the second direction D2 (for example, on the upper side of FIG. 1). It is divided into regions on the other side (for example, the lower side of FIG. 1). In addition, the second partition 32 divides the front surface 10b side of the side material 10 into one side and the other side of the first direction D1, and the second partition portion 32 is formed on the back surface 10c of the side material 10, for example. It has not been.

The first partition portion 31 is curved toward the center of the side material 10 in the second direction D2 toward the center of the side material 10 in the first direction D1. For example, the first partition 31 is curved in an arc shape. Each 2nd partition part 32 inclines toward both ends in the 1st direction D1 of the side material 10 as it separates from the 1st partition part 31. That is, the pair of second partition portions 32 extend in the directions inclining in both the first direction D1 and the second direction D2, and in the directions away from each other as the distance from the first partition portion 31 increases. For example, each second partition 32 extends linearly.

The partition part 30 may further include a pair of third partition parts 33 extending in a direction inclined in both the first direction D1 and the second direction D2 on the back surface 10c of the side material 10. The pair of third partition portions 33 are provided, for example, at positions near the first long side 2b of the center O2 of the back surface 10c, and partition a part of the internal space S. The pair of third partition portions 33 may be provided between the pair of second partition portions 32 and may be arranged symmetrically with respect to the central axis L2. As an example, the third partition 33 is inclined toward the center O2 side of the back surface 10c toward the center in the first direction D1.

The first partition portion 31 is sewn on the front surface 10b and the back surface 10c of the side material 10. The second partition 32 is sewn on the front surface 10b of the side material 10, and the third partition 33 is sewn on the back surface 10c of the side material 10. Seams of the first partition 31 and the second partition 32 are formed on the front surface 10b, and seams of the first partition 31 and the third partition 33 are formed on the back surface 10c.

The content 20 is accommodated in the internal space S inside the inner lining 50, and the content 20 includes, for example, a flexible material 21, a granular body 22, and a granular body 23. As shown in FIGS. 1 and 6, on each of both ends in the first direction D1 of the pillow 1, for example, a third internal space S3 is formed in the lower portion on the first long side 2b side of the first partition 31. Has been done.

The flexible material 21 is accommodated in the first internal space S1, and the flexible material 21 is, for example, cotton (cotton) containing granular cotton made of polyethylene, urethane, or feathers. The mass of the flexible material 21 accommodated in the first internal space S1 is, for example, 40 g or more and 50 g or less. The flexible material 21 is put into and taken out from the first cloth portion 51 in the first internal space S1, and specifically, the flexibility is provided through the tubular first cloth portion 51 that is pulled out by opening the first fastener 41. The material 21 is put into and taken out of the first internal space S1. Thereby, the amount of the flexible material 21 accommodated in the first internal space S1 can be appropriately changed.

The granular material 22 is accommodated in the third internal space S3, for example. The granular body 22 may be a hollow granular body that is hollow. A large number of voids are retained in the third internal space S3 by accommodating the granular body 22. The granular body 22 is, for example, a hollow pipe material or beads. As an example, the granular body 22 is a polyethylene pipe material having a cylindrical shape. However, the granular body 22 may be a solid granular body such as buckwheat hull, cypress or adzuki bean.

The mass of the granular material 22 accommodated in the third internal space S3 is, for example, 420 g or more and 510 g or less. The granular material 22 is put into and taken out from the second cloth portion 52 in the third internal space S3. Specifically, the granular body 22 is put into and taken out of the third internal space S3 via the tubular second cloth portion 52 in which the second fastener 42 is opened and pulled out. Thereby, the amount of the granular bodies 22 accommodated in the third internal space S3 can be changed as appropriate.

FIG. 7 is a sectional view taken along line VII-VII of FIG. As shown in FIGS. 1, 6 and 7, on the center side of the pillow 1 in the first direction D1, for example, a third internal space S3 is provided on the first long side 2b side of the first partition 31. Thus, the fourth internal space S4 is provided on the second long side 2c side of the first partition section 31. The granular body 23 is accommodated in the fourth internal space S4. The granular body 23 may be similar to the granular body 22 described above, for example. The granular body 23 may be a hollow pipe material or beads.

The mass of the granular body 23 accommodated in the fourth internal space S4 is, for example, 220 g or more and 290 g or less. The granular body 23 is put into and taken out from the third cloth portion 53 in the fourth internal space S4. Specifically, the granular body 23 is put into and taken out of the fourth internal space S4 through the tubular third cloth portion 53, which is pulled out by opening the third fastener 43. Thereby, the amount of the granular material 23 accommodated in the fourth internal space S4 can be changed as appropriate.

Next, the function and effect obtained from the pillow 1 according to the present embodiment will be described in detail. For example, as shown in FIG. 5, the pillow 1 includes a rectangular parallelepiped side land 10 having a pair of long sides 2 extending in the first direction D1 and a pair of short sides 3 extending in the second direction D2. A content 20 is accommodated in the internal space S of 10. Moreover, the pillow 1 includes a plurality of partition sections 30 that partition the internal space S of the pillow 1.

The plurality of partition sections 30 include a first partition section 31 extending from one (first short side 3b) of the pair of short sides 3 to the other (second short side 3c) in the first direction D1, and from the first partition section 31. It includes a pair of second partition portions 32 that extend toward the first long side 2b and are arranged along the first direction D1. And the 1st partition part 31 is curving toward the center side of the 2nd direction D2 as it goes to the center of the 1st direction D1, and each 2nd partition part 32 of the 1st direction D1 moves away from the 1st partition part 31. It is inclined to both ends.

Therefore, the head M2 of the user M is placed on the first long side 2b side of the first partition 31 and the opposite side of the first partition 31 from the first long side 2b (the second long side 2c side). When the neck M1 of the user M is placed on, the head M2 and the neck M1 of the user M move in an arc shape along the curved first partition 31 when the user turns over. That is, the first partition section 31 is provided along the movement trajectory T of the head M2 and the neck M1. As a result, the frequency of the head M2 and the neck M1 crossing the hard first partition portion 31 at the time of turning over is reduced, and the head M2 and the neck M1 move along the first partition portion 31, so that the head M2 and the neck M1. It is possible to suppress pressure on the body and make it easier to turn over at bedtime.

Moreover, each 2nd partition part 32 inclines diagonally to the both ends of the 1st direction D1 as it separates from the 1st partition part 31. Therefore, since each of the second partition portions 32 is inclined toward both end sides in the first direction D1 as the second partition portion 32 is separated from the first partition portion 31, the head M2 and the neck M1 of the user M at the time of turning over are the second partition portions. The frequency of crossing 32 can be reduced. Therefore, it is possible to make it difficult for the head M2 and the neck M1 to cross the hard second partition 32, so that the rolling property can be improved.

As shown in FIGS. 5 and 7, the internal space S includes a pair of first internal spaces S1 located at both ends of the pair of second partition sections 32 in the first direction D1 and a pair of first internal spaces. The content 20 includes a second internal space S2 located between the spaces S1, and the content 20 includes a flexible material 21 accommodated in each first internal space S1 and a side material 10 in the second internal space S2. A sheet material 60 that contacts the back side of the surface 10b and is harder than the flexible material 21 may be included. In this case, when the head M2 of the user M is placed between the pair of second partition portions 32, the head M2 comes into contact with the sheet material 60 that is harder than the flexible material 21 via the side ground 10. Therefore, when the head M2 comes into contact with the hard sheet material 60 via the side ground 10, it is possible to prevent the head M2 from sinking and smoothly turn over.

The flexible material 21 is housed in each of the first internal spaces S1 located at both ends of each of the second partition portions 32 in the first direction D1. Therefore, when the user M rolls over and the head M2 reaches the second partition 32, the cheek M3 of the user M is placed on the upper portion of the flexible material 21, and thus reaches the second partition 32. The head M2 of the user M who is lying sideways can be sunk into the flexible material 21. Therefore, it is possible to reduce pressure on the cheeks M3 when lying sideways, and to gently support the cheekbones. Furthermore, it is possible to prevent the head M2 from falling off the pillow 1 when lying sideways.

The sheet material 60 may include a mesh material 65 that contacts the back side of the surface 10 b of the side material 10. In this case, when the head M2 of the user M is placed between the pair of second partition portions 32, the head M2 rotates the lateral ground 10 and contacts the mesh material 65. Therefore, the air permeability of the region where the head M2 is placed (between the pair of second partition portions 32) can be enhanced. Therefore, it is possible to prevent heat and moisture from staying in the head M2 and to suppress stuffiness of the head M2, so that the comfort of the user M can be improved.

As shown in FIGS. 6 and 7, the internal space S includes a third internal space S3 located below the pair of first internal spaces S1 and below the second internal space S2. The thing 20 may include the granular body 22 accommodated in the 3rd internal space S3. In this case, the granular material 22 is accommodated in the third internal space S3 located below the first internal space S1 and the second internal space S2. Therefore, the head M2 of the user M placed above the pair of the first internal space S1 or the second internal space S2 can be firmly supported by the granular body 22.

The internal space S includes a fourth internal space S4 located closer to the second long side 2c than the first partition portion 31, and the content 20 includes a granular body 23 accommodated in the fourth internal space S4. But it's okay. In this case, when the neck M1 of the user M is placed on the side of the second long side 2c located on the opposite side of the first long side 2b, it is accommodated in the fourth internal space S4 on the side of the second long side 2c. The granular body 23 can enhance the air permeability of the portion on which the neck M1 is placed and the fluidity of the content 20. Therefore, it is possible to firmly support the neck M1 of the user M and suppress stuffiness and heat buildup of the neck M1, so that the user M can be provided with more comfortable sleeping comfort.

The partition section 30 may include a third partition section 33 that partitions a part of the third internal space S3. In this case, it is possible to suppress excessive flow of the granular material 22 housed in the third internal space S3. That is, since the excessive flow of the granular material 22 under the head M2 of the user M can be suppressed, the shape of the region between the pair of second partition parts 32 can be stabilized. Therefore, it is possible to provide the user M with a better sleeping comfort.
