Description

FIELD OF THE DISCLOSURE The present disclosure relates to side sleeping pillows upon which a user's body rests.

2. Description of the Related Art Conventionally, various types of pillows have been known for accommodating users who sleep on their side. Japanese Utility Model Registration No. 3111458 describes a pillow for a side sleeping posture that corresponds to sleeping in a sideways posture. The side sleeping posture support pillow includes an occipital head supporting portion that supports the occipital region, and a temporal support portion that is continuous with the occipital head corresponding portion and supports the temporal region. The occipital region corresponding portion and the temporal region corresponding portion have different shapes.

The height of the corresponding part of the temporal region is higher than the height of the corresponding part of the occipital region, and the corresponding part of the temporal region has a shape close to a rectangle, whereas the corresponding part of the occipital region extends long from the corresponding part of the temporal region. It is said that In plan view, the occipital region corresponding portion obliquely extends from one corner of the rectangular temporal region corresponding portion. In addition, a slightly recessed ear corresponding portion is formed at the top of the temporal region corresponding portion. Furthermore, the size of the temporal portion corresponding portion is substantially the same as the shoulder width of the user.

Utility Model Registration No. 3111458

Since the side sleeping posture support pillow described above includes the side head corresponding part and the back head corresponding part, it is possible to support the head of the user who sleeps sideways. By the way, especially in recent years, apnea syndrome has been regarded as a problem, and various proposals have been made to suppress the symptoms of apnea. Side sleeping is one of them, and it is known that sleeping on the side reduces the duration of apnea.

Although the aforementioned side sleeping posture pillow is a pillow that supports side sleeping, it does not allow the user to continue side sleeping. In other words, although the pillow for side sleeping posture can support the side of the user's head because it has a side-side corresponding part, it is not considered to support the entire body of the user who sleeps on the side. not Therefore, even if the user sleeps on his/her side, if the user rolls over, he/she will be on his or her back, and therefore the duration of apnea cannot be sufficiently reduced. Therefore, it is demanded that sleep on the side can be continued to further reduce apnea.

SUMMARY OF THE DISCLOSURE It is an object of the present disclosure to provide a side sleeping pillow that can sustain side sleeping and reduce apnea.

A side sleeping pillow according to one aspect of the present disclosure includes a first portion on which a user's head and neck rest and a second portion on which the user's back rests. The second portion extends in a second direction crossing the first direction from the end of the first portion in the first direction, and the length of the second portion in the second direction is The inner space of the first portion and the inner space of the second portion are separated from each other by a partition portion, and the hardness of the second portion is greater than that of the first portion. The hardness is higher than that of the second part, the weight of the second part is larger than the weight of the first part, and the first contents can be put in and taken out of the inner space of the first part. , the second content can be put in and taken out, and the hardness of the second content is higher than the hardness of the first content .

In this side sleeping pillow, the first portion extending in the first direction supports the head and neck of the user sleeping on the side, and the second portion extending in the second direction intersecting the first direction supports the user's head and neck. Support your back. Therefore, since the back is supported by the second portion extending in a direction different from the first portion that supports the head and neck, the back of the user sleeping on the side can be firmly supported by the second portion. Further, since the length of the second portion extending in the second direction is longer than the length of the first portion extending in the first direction, the volume of the second portion can be increased. You can suppress lying on your back by doing more firmly. Therefore, side sleeping can be continued more reliably. Further, the hardness of the second portion is harder than the hardness of the first portion and the weight of the second portion is greater than the weight of the first portion. Therefore, by supporting the head and neck with the relatively light and soft first portion, it is possible to improve the sleeping comfort of the user. can be suppressed more reliably. Therefore, it is possible to improve sleep comfort and to continue sleeping on one's side, thereby suppressing apnea.

The first portion and the second portion described above are L-shaped, and the partition may extend from an inner corner of the L-shape to an outer corner of the L-shape. In this case, since the partition portion, which is the boundary between the second portion and the first portion, extends obliquely with respect to both the first direction and the second direction, the area of the second portion that supports the user's back can be enlarged. can be done. Therefore, it is possible to more reliably suppress lying on one's back and continue sleeping on one's side, thereby more reliably suppressing apnea.

Since the hardness of the second content is higher than the hardness of the first content, the amount of the second content can be adjusted to change the hardness and weight of the second portion. Therefore, if the second portion feels too hard or too heavy, the amount of the second content can be reduced to make the second portion softer and lighter, and the second portion feels too soft or too light. If so, the amount of second content can be increased to make the second portion even harder and heavier. In addition, since the first content can be put in and taken out of the first portion, the feel of the first portion can be adjusted. Therefore, it is possible to provide a side sleeping pillow that meets the user's preference and the user's situation.

The second content may be granules made of cypress, red bean, or polyethylene. Hinoki and adzuki bean are heavy in weight and high in hardness and density compared to other contents. Therefore, by storing cypress as the second content in the second portion, the second portion can be made hard with a small amount of the second content. As a result, the hardness of the second portion can be adjusted more easily. In addition, polyethylene granules have the advantage of being highly versatile and readily available.

According to the present invention, sleep on the side can be continued to reduce apnea.

In addition, the drawings may be partially simplified or exaggerated for easy understanding, and the dimensional ratios and the like are not limited to those described in the drawings.

(First embodiment)
FIG. 1 is a perspective view showing a side sleeping pillow 1 according to this embodiment. FIG. 2 is a perspective view of the side sleeping pillow 1 viewed from a direction different from that of FIG. FIG. 3 is a perspective view of the side sleeping pillow 1 viewed from a direction different from that of FIGS. 1 and 2. FIG. The side-sleeping pillow 1 is, for example, a pillow that forces the user M (see FIG. 6(a)) to sleep on his side (prevents him from lying on his back). apnea.

Especially in recent years, apnea syndrome has been viewed as a problem, and when apnea syndrome occurs, for example, it becomes a state of lack of sleep, and even when awake, it causes various problems such as fatigue and difficulty in concentrating. Life can be disrupted. Therefore, for example, it is known that if a patient with apnea syndrome or the like sleeps on his or her side, the apnea will subside. is.

As shown in FIGS. 1 to 3, a side sleeping pillow 1 according to this embodiment is formed in, for example, an L shape, and has a first portion 2 extending in a first direction D1 and a first portion 2 extending in a first direction D1. and a second portion 3 extending in a second direction D2 from an end in the first direction D1 of the. For example, the first direction D1 indicates the width direction of the body of the user M lying on the mattress, and the second direction D2 indicates the longitudinal direction of the body of the user M. As an example, the first direction D1 and the second direction D2 are orthogonal to each other.

The first part 2 has a mesh fabric 1a on the surface of the side sleeping pillow 1, and the presence of the mesh fabric 1a on the surface prevents heat even when the body is in close contact with the side sleeping pillow 1 for a long time. It can be made difficult to feel. That is, the mesh fabric 1a enhances the air permeability and heat dissipation of the side sleeping pillow 1, thereby providing the user M who comes in contact with the side sleeping pillow 1 with a cool feeling. The first portion 2 may have the mesh fabric 1a on the back side of the side sleeping pillow 1, or the back side of the side sleeping pillow 1 may be made of a fabric different from the mesh fabric 1a. The second part 3 also comprises a mesh fabric 1b similar to the mesh fabric 1a.

For example, the first portion 2 is a portion on which the head M1 and neck M2 of the user M are placed, and the second portion 3 is a portion on which the back M3 of the user M is applied (see FIG. 6(a)). . The second portion 3 is arranged along the back M3 of the user M and can firmly support the back M3 by extending long in the second direction D2. The first portion 2 and the second portion 3, for example, both extend linearly.

The length of the first portion in the first direction D1 is, for example, 20 cm or more and 50 cm or less, or may be 30 cm or more and 40 cm or less, and can be changed as appropriate. The first portion 2 includes a first end portion 2a positioned at an end portion in the first direction D1, a first outer side portion 2b extending from the first end portion 2a to the outside of the L shape of the side sleeping pillow 1, It has a first inner side portion 2c extending from one end portion 2a to the inside of the L shape.

The first end 2a constitutes the end of the side sleeping pillow 1 in the first direction D1. The first end 2a may be made of, for example, a fabric different from the mesh fabric 1a. As an example, the fabric of the first end portion 2a is harder and harder to stretch than the mesh fabric 1a. The first end portion 2a may be divided into two locations along the second direction D2 via the partition portion 7 . The first outer side portion 2b extends curvedly along the first direction D1 from one end of the first end portion 2a, and the first inner side portion 2c extends in the first direction D1 from the other end of the first end portion 2a. curved and extending along the The first outer side portion 2b and the first inner side portion 2c may, for example, extend parallel to each other.

The side sleeping pillow 1 comprises a fastener 4 for adjusting the amount of the first content inside the first portion 2 . The first content indicates the content accommodated in the internal space of the first portion 2, and is, for example, a straw-shaped pipe material made of polyethylene. However, the type of the first content is not particularly limited. The first content may be cotton, for example, and can be changed as appropriate. A fastener 4 is provided on the outside of the L shape of the side sleeping pillow 1. - 特許庁As a result, the position of the fastener 4 can be separated from the position of the body of the user M, so that the possibility that the fastener 4 hits the body of the user M and impairs the sleeping comfort of the user M can be reduced. It is possible to adjust the amount of the first content accommodated in the first portion 2 with the fastener 4 opened.

The first part 2 has an outer part 2A located outside the L shape of the side sleeping pillow 1 and an inner part 2B located inside the L shape. The outer portion 2A is a portion on which the user M's head M1 (especially temporal region) is placed, and the inner portion 2B is a portion on which the user M's neck M2 (neck) is placed. The outer portion 2A and the inner portion 2B are separated from each other by a partition portion 7 extending from the first end portion 2a in the first direction D1.

Since the outer portion 2A and the inner portion 2B are partitioned from each other in this manner, the amount of the first content inside the outer portion 2A and the amount of the first content inside the inner portion 2B are individually controlled. can be adjusted to Therefore, it is possible to individually adjust the height of the outer portion 2A on which the head M1 is placed and the height of the inner portion 2B on which the neck M2 is placed according to the preference of the user M or the situation of the user M. can.

The partition portion 7 extends from the first end portion 2 a to the middle portion of the first portion 2 . That is, the partition part 7 partially partitions the first portion 2 and does not completely partition the first portion 2 . As a result, the number of fasteners 4 to be opened and closed to adjust the amount of the first content accommodated in the outer portion 2A and the amount of the first content accommodated in the inner portion 2B can be reduced to one. . As a result, it contributes to the cost reduction of the side sleeping pillow 1 .

A partition 6 is provided between the first portion 2 and the second portion 3 . The partition portion 6 extends in a direction crossing both the first direction D1 and the second direction D2, and extends diagonally with respect to both the first direction D1 and the second direction D2. The partition 6 extends, for example, from the inner corner of the L-shape of the side sleeping pillow 1 to the outer corner of the L-shape. That is, the partition portion 6 extends from the boundary between the first outer side portion 2 b and the second portion 3 to the boundary between the first inner side portion 2 c and the second portion 3 . In other words, the partition 6 obliquely extends from the inner corner of the L-shape of the side sleeping pillow 1 toward the user's M head M1. The partition part 6 completely separates the first part 2 and the second part 3 , and is configured such that the first content accommodated inside the first part 2 cannot move to the second part 3 .

The second portion 3 extends from the partition portion 6 in the second direction D2, for example, linearly. The length of the second portion 3 in the second direction D2 is longer than the length of the first portion 2 in the first direction D1, and may be, for example, 40 cm or more and 130 cm or less, or 50 cm or more and 70 cm or less. The second part 3 is heavier than the first part 2 and harder than the first part 2 . Furthermore, the volume of the second portion 3 may be larger than the volume of the first portion 2 .

The second portion 3 includes a second end portion 3a located at the end portion in the second direction D2, and a second outer side extending from the second end portion 3a in the second direction D2 on the outer side of the L shape of the side sleeping pillow 1. and a second inner side 3c extending in the second direction D2 from the second end 3a to the inner side of the L-shape of the side sleeping pillow 1. As shown in FIG. The second end 3a constitutes the end of the side sleeping pillow 1 in the second direction D2. The second outer side portion 3b extends in the second direction D2 from one end of the second end portion 3a, and the second inner side portion 3c extends in the second direction D2 from the other end of the second end portion 3a.

The second outer side portion 3b and the second inner side portion 3c may, for example, extend parallel to each other. The second outer side portion 3b and the second inner side portion 3c both extend from the second end portion 3a toward the partition portion 6. As shown in FIG. The boundary between the second outer side portion 3b and the first portion 2 (the portion where the second outer side portion 3b contacts the partition portion 6) is the boundary between the second inner side portion 3c and the first portion 2 (the second inner side It is positioned farther from the second end portion 3a than the portion where the portion 3c contacts the partition portion 6).

The second outer side 3b is provided with a fastener 5 for adjusting the amount of the second content 11 (see FIG. 4(a)) inside the second portion 3. As shown in FIG. The second content 11 indicates the content accommodated in the inner space of the second portion 3, and is, for example, a rectangular parallelepiped granular body made of cypress, as shown in FIG. 4(a). The second portion 3 may be filled with a plurality of second contents 11, in which case the weight and hardness of the second portion 3 can be increased. As an example, the second content 11 includes six flat portions 11a and chamfered portions 11b provided at the four corners of each flat portion 11a. That is, the second content 11 may be a cubic cypress granular body with rounded corners. Also, the second content 11 may be a granular body made of adzuki bean, and the material, shape and size of the second content 11 can be changed as appropriate.

As shown in FIG. 4( b ), the second portion 3 may be filled with the second content 12 instead of or together with the second content 11 . The second content 12 is made of resin, such as polyethylene. The second content 12 is in the shape of a hollow sphere with a part cut away. That is, the second content 12 has a spherical outer surface 12a and a circular opening 12b formed in the outer surface 12a. This shape increases the hardness of the second content 12 .

For example, as shown in FIGS. 2 and 5, the fastener 5 is provided on the second outer side portion 3b of the second portion 3. As shown in FIG. Since the fastener 5 is provided on the outer side of the L-shape of the side sleeping pillow 1 in this way, the fastener 5 can be separated from the position of the user M as described above. It is possible to reduce the possibility of impairing the sleeping comfort of the user M by hitting the body. It is possible to adjust the amount of the second content 11 or the second content 12 accommodated in the second portion 3 with the fastener 5 opened.

FIG. 5 is a diagram showing a state in which the fastener 5 is opened and the inner bag 13 located inside the second portion 3 (mesh cloth 1b) protrudes from the second portion 3. As shown in FIG. The inner bag 13 is accommodated in a rolled state inside the second portion 3 when the fastener 5 is closed. The inner bag 13 is pulled out from the inside of the second portion 3 in a state in which the fastener 5 is released, thereby projecting from the second portion 3. In this state, the second content 11 is placed inside the inner bag 13. , 12 can be moved in and out. The opening 14 of the inner bag 13 is a gateway for the second contents 11 and 12 to the internal space of the second portion 3 . In addition, the inner bag 13 may be provided inside the fastener 4 provided in the first portion 2, and in this case, the amount of the first content can be adjusted in the same manner as described above.

Next, the effects obtained from the side sleeping pillow 1 according to the first embodiment will be described in detail. As shown in FIG. 6(a), in the side sleeping pillow 1, the first portion 2 extending in the first direction D1 supports the head M1 and neck M2 of the user M and crosses the first direction D1. A second portion 3 extending in the second direction D2 supports the user's M back M3. Therefore, the second portion 3 extending in a direction different from the first portion 2 supporting the head M1 and neck M2 supports the back M3 of the user M. Therefore, since the back M3 is supported by the second portion 3 extending in a direction different from the first portion 2 that supports the head M1 and the neck M2, the back M3 of the user M who sleeps on his side is supported by the second portion 3. It can hold up well.

Further, since the length of the second portion 3 extending in the second direction D2 is longer than the length of the first portion 2 extending in the first direction D1, the volume of the second portion 3 can be increased. The back M3 can be supported more firmly by the portion 3 to suppress lying on the back. Therefore, side sleeping can be continued more reliably. Furthermore, the hardness of the second portion 3 is harder than the hardness of the first portion 2 and the weight of the second portion 3 is greater than the weight of the first portion 2 .

Therefore, by supporting the head M1 and the neck M2 with the relatively light and soft first portion 2, the user M can be comfortable in bed, and by supporting the back with the heavy and hard second portion 3. , it is possible to more reliably suppress lying on one's back. Therefore, it is possible to improve sleep comfort and to continue sleeping on one's side, thereby suppressing apnea.

The first portion 2 and the second portion 3 are L-shaped, and the partition portion 6 may extend from the inner corner of the L-shape to the outer corner of the L-shape. In this case, the partition 6, which is the boundary between the second portion 3 and the first portion 2, extends obliquely with respect to both the first direction D1 and the second direction D2. 3 can be enlarged. Therefore, it is possible to more reliably suppress lying on one's back and continue sleeping on one's side, thereby more reliably suppressing apnea.

A first content can be put in and taken out from the inner space of the first part 2, and second contents 11 and 12 can be put in and taken out from the inner space of the second part 3. , 12 may be higher than the hardness of the first content. In this case, since the hardness of the second contents 11, 12 is higher than the hardness of the first contents, the amount of the second contents 11, 12 is adjusted to change the hardness and weight of the second part 3. be able to.

Therefore, when the second part 3 feels too hard or too heavy, the amount of the second contents 11, 12 can be reduced to make the second part 3 softer and lighter, and the second part 3 is softer. The amount of second contents 11, 12 can be increased to make the second portion 3 harder and heavier if it is felt to be too or too light. Further, since the first content can be put in and taken out from the first portion 2, the feel of the first portion 2 can be adjusted. Therefore, it is possible to provide the side sleeping pillow 1 according to the preference of the user M or the situation of the user M.

The second contents accommodated in the second part 3 are the second contents 11 which are cypress granules, the second contents which are adzuki bean granules, or the second contents which are polyethylene granules. It may be an object 12. Hinoki and adzuki bean are heavy in weight and high in hardness and density compared to other contents. Therefore, by accommodating Japanese cypress or red bean as the second content in the second portion, the second portion 3 can be hard and heavy with a small amount of the second content. As a result, the hardness of the second portion 3 can be adjusted more easily. In addition, the second content 12, which is a polyethylene granule, has the advantage of being highly versatile and readily available.

The side sleeping pillow 1 may include an inner bag 13 positioned inside the zipper 5 (zipper 4) and protruding from the second portion 3 (first portion 2). In this case, since the second contents 11 and 12 (first contents) can be taken in and out with the inner bag 13 projecting outward, the contents are less likely to spill when the contents are taken in and out. be able to. Therefore, the contents can be put in and taken out easily and smoothly.

As described above, the side sleeping pillow 1 can be used by placing the head M1 and neck M2 of the user M on the first portion 2 and placing the back M3 of the user M on the second portion 3. be done. However, as shown in FIG. 6B, for example, the user M's head M1 and neck M2 are placed on the first portion 2, and the second portion 3 extending in the second direction D2 is held. good too.

That is, the side sleeping pillow 1 may be hugged so that the abdomen of the user M faces the second portion 3 . In this case, the side sleeping pillow 1 can be used as a body pillow, and the side sleeping of the user M can be continued by holding the second part 3 while the user M is sleeping sideways. be able to. Therefore, the apnea of the user M can be suppressed as described above.

(Second embodiment)
Next, a side sleeping pillow 21 according to a second embodiment will be described with reference to FIG. The side sleeping pillow 21 according to the second embodiment differs from the first embodiment in the configuration of the first portion 22 . In the following description, the description overlapping with that of the first embodiment will be omitted as appropriate. The side sleeping pillow 21 is, for example, a side sleeping pillow used by a patient with apnea syndrome in a hospital, and the mesh fabrics 1a and 1b on the surface of the side sleeping pillow 21 may be fabrics that are relatively difficult to stretch. . Further, the second portion 3 may be filled with the second content 11 made of Japanese cypress. As described above, the second portion 3 extending long in the second direction D2 is filled with the hard and heavy second contents 11 made of cypress, so that the user M can continue to sleep sideways more reliably. can.

The first portion 22 comprises an outer portion 22A located outside the L-shape of the side sleeping pillow 21 and an inner portion 22B located inside the L-shape. completely separated through The partition 7 extends from the first end 2 a of the first portion 22 to the partition 6 . The inner space of the outer portion 22A and the inner space of the inner portion 22B both contain, for example, the above-described first contents. A fastener 4 is provided on the first outer side portion 2 b of the first portion 22 , and a fastener 24 is provided on the first inner side portion 2 c of the first portion 22 . By opening and closing the fastener 4, the amount of the first content in the outer portion 22A can be adjusted, and by opening and closing the fastener 24, the amount of the first content in the inner portion 22B can be adjusted.

As described above, in the side sleeping pillow 21 according to the second embodiment, the length of the second portion 3 extending in the second direction D2 is longer than the length of the first portion 22 extending in the first direction D1. Since the volume of 3 can be increased, the back M3 can be more firmly supported by the second portion 3 to prevent the user from lying on his/her back. Furthermore, by supporting the head M1 and the neck M2 with the relatively light and soft first portion 22, the user M can be comfortable in bed, and by supporting the back with the heavy and hard second portion 3. , it is possible to more reliably suppress lying on one's back. Therefore, it is possible to improve sleep comfort and to continue sleeping on one's side, thereby suppressing apnea in the same manner as in the above-described first embodiment.

In the side sleeping pillow 21 according to the second embodiment, the outer portion 22A and the inner portion 22B of the first portion 22 are completely separated by the partition portion 7 . Therefore, the amount of the first content in the outer portion 22A and the amount of the first content in the inner portion 22B can be individually adjusted. Therefore, the amount of the first content of the outer portion 22A on which the head M1 is placed and the amount of the first content of the inner portion 22B on which the neck M2 is placed can be individually adjusted, so that the outer portion 22A and the inner portion The height and hardness of 22B can be appropriately adjusted according to user's M preference and user's M condition.
