Description

Body pillow

の一 One aspect of the present disclosure relates to a body pillow used when resting the body.

Conventionally, various pillows have been known. Japanese Patent Application Laid-Open No. 2014-168607 describes a rod-shaped body pillow that extends along a human body. This body pillow is composed of a long main body that a user holds and a headrest portion on which the user's head is placed. An ellipsoidal balloon made of an elastic body such as rubber is embedded in the main body. An air pump connected to the balloon via a flexible tube is provided outside the main body.

The flexible tube extends from the end of the main body to the outside of the main body. The air pump is provided with a valve, and the valve receives a signal from a control unit (CPU) and controls air supply from the air pump to the balloon. The control unit outputs signals to the air pump and the valve. As the air pump is driven, the valve opens the air passage of the flexible tube and air is supplied to the balloon, so that the body pillow is inflated.

Japanese Utility Model Registration No. 3194451 discloses a rod-shaped body pillow that is curved in an arc. The body pillow includes an airbag containing a cotton-like fibrous body, a body pillow body that covers the airbag, an air pump that supplies and exhausts air to the airbag, and a control unit that controls air supply and exhaust of the air pump. With. The cotton-like fibrous body is made of absorbent cotton and is filled in the airbag.

The air pump is connected to the airbag via an air hose extending from the body of the body to the outside of the body of the body. The air pump includes a power source and an operation button, and operates by operating the power source and the operation button. The control unit further extends from the air pump. The control unit controls the driving of the air pump so that the air pump supplies and exhausts the air bag with a supply time of 4 seconds and an exhaust time of 6 seconds.

JP 2014-168607 A Utility Model Registration No. 3194451

In the above-mentioned body pillow, an air hose extends from the body of the body pillow to the outside, and an air pump is provided at the end of the air hose opposite to the body of the body pillow. In this way, when the air hose extends from the body pillow and an air pump is provided further ahead of the air hose, the air hose may be entangled with the body pillow user or the air pump may come into contact with the user's body. . Therefore, the air hose or the air pump located outside the body pillow may get in the way, which may impair the user's comfort.

In addition, the above-described body pillow expands or contracts by supplying and exhausting air according to a signal from the control unit. Therefore, when the user is hugging the body pillow, the body pillow may expand or contract without permission, and the user may feel troublesome to use the body pillow. Therefore, since the use of the pillow itself becomes troublesome, the user feels that the pillow is not comfortable and the pillow is often not used.

This disclosure aims to provide a pillow that can be comfortably used while improving the user's comfort.

A body pillow according to the present disclosure includes a non-breathable bag body, an inflow portion that is provided in the bag body and is openable and closable and allows air to flow into the bag body in an open state, and is provided in the bag body And an outflow part that allows the air to flow out from the inside of the bag body to the outside of the bag body in an open state. The inflow portion includes an opening provided in the bag body, and an elastic foam member that is provided inside the opening of the bag body to be compressed and deformed and through which air can flow. When the compressed and deformed elastic foam member returns to its original shape, the elastic foam member sucks air into the bag body, so that air flows into the bag body.

In this body pillow, the non-breathable bag body is provided with both an inflow portion for allowing air to flow into the bag body and an outflow portion for allowing air to flow out from the inside of the bag body to the outside of the bag body. Therefore, the inflow portion and the outflow portion are provided in the bag body itself, and there is no air hose or the like extending outside from the body pillow. Therefore, since it can suppress that the part extended outside from a body pillow contacts a user's body, the situation where a user's sleeping comfort is impaired can be avoided. Further, in this body pillow, the inflow portion has an opening and an elastic foam member, and the inflow portion sucks air into the bag body when the compression-deformed elastic foam member returns to the shape of the bag body. Inflow of air into the interior. Accordingly, when the inflow portion is opened and the compression deformation is released in a state where the elastic foam member is compressed and deformed, air flows into the bag body while the elastic foam member expands. Therefore, the air can be easily introduced into the bag body by repeating the compression and decompression of the elastic foam member after opening the inflow portion. Moreover, the air outflow from the inside of the bag body to the outside of the bag body can be easily performed by opening the outflow portion. Therefore, since air can be easily flowed into the bag body and air can be flowed out of the bag body, the dakimakura can be easily expanded and contracted. Accordingly, since the hardness of the body pillow can be easily changed according to the user's preference, the body pillow can be used comfortably and comfortably.

Further, the bag body may have a shape extending along the body of the user of the body pillow, and at least one of the inflow portion and the outflow portion may be provided at the end portion of the bag body. In this case, by providing at least one of the inflow portion and the outflow portion at the end of the bag body, at least one of the inflow portion and the outflow portion can be made difficult to hit the user's back or waist. Therefore, it is possible to provide the user with a more comfortable sleeping comfort.

According to the pillow according to the present disclosure, it is possible to make the user comfortable and to use comfortably.

Hereinafter, embodiments of the body pillow according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and repeated description is omitted as appropriate. Further, the drawings may be simplified or exaggerated for easy understanding, and dimensions and the like are not limited to those described in the drawings.

(First embodiment)
FIG. 1 is a plan view showing a body pillow 1 according to the first embodiment. The body pillow 1 is constituted by a non-breathable bag body 10 and is an air body pillow whose shape and hardness can be adjusted by changing the amount of air accommodated in the interior of the bag body 10. As shown in FIG. 1, the body pillow 1 as a whole extends linearly and has a shape in which both ends are bent, for example, a seahorse shape. The material of the bag body 10 is, for example, a vinyl material such as PVC, polyurethane, or polyester, but can be appropriately changed.

The bag body 10 includes an arm contact portion 2 with which an arm M1 of the user M (see FIG. 5) contacts, an extension portion 3 extending from the arm contact portion 2 along the body of the user M, and an extension portion 3. On the side opposite to the arm contact portion 2, a leg rest portion 4 on which a leg M2 of the user M is placed is provided. The extending part 3 extends long along the first direction D1 along the body of the user M. The arm contact portion 2 is provided at one end of the extending portion 3 in the first direction D1, and the leg rest portion 4 is provided at the other end of the extending portion 3 in the first direction D1.

The arm contact portion 2 extends in a second direction D2 intersecting the first direction D1 at one end of the extension portion 3 in the first direction D1. For example, the leg rest portion 4 is in the first direction D1 of the extension portion 3. At the other end, the third direction D3 extends in the opposite direction of the second direction D2. As described above, the second direction D2 in which the arm contact portion 2 extends from the extending portion 3 and the third direction D3 in which the leg rest portion 4 extends from the extending portion 3 are opposite to each other.

The arm contact portion 2 has a first end 2a, a second end 2b, an inner curved portion 2c, and an outer curved portion 2d. The first end 2a is located at the tip in the second direction D2. The second end 2b constitutes one end of the bag body 10 in the first direction D1. The inner curved portion 2c extends from the first end portion 2a to the opposite side of the second end portion 2b and extends from the first end portion 2a toward the extending portion 3. The outer curved portion 2d extends from the second end portion 2b toward the extending portion 3. As an example, the length of the arm contact portion 2 (second end portion 2b) in the second direction D2 is not less than 20 cm and not more than 50 cm, but can be changed as appropriate.

In the inner curved portion 2c, for example, a plurality of ridges 2e extending toward the inner side of the arm contact portion 2 are formed. The first end 2a is curved, for example, in an arc shape, and the second end 2b extends linearly from the first end 2a toward the outer curved portion 2d. The inner curved portion 2c is curved so as to enter the inside of the arm contact portion 2 from the first end portion 2a. For example, the inner curved portion 2c is curved inside the arm contact portion 2 in an arc shape. As an example, the radius of curvature of the inner curved portion 2c is smaller than the radius of curvature of the first end 2a. That is, the degree of curvature of the inner curved portion 2c is tighter than the degree of curvature of the first end 2a. The outer curved portion 2d is gently curved from the opposite side of the second end 2b to the first end 2a, and is curved, for example, in an arc shape.

The extending portion 3 extends between the arm contact portion 2 and the leg rest portion 4 in the first direction D1 as a whole. The extending part 3 is inclined in the third direction D3 as it goes to the arm contact part 2, and is inclined in the second direction D2 as it goes to the leg rest part 4. Therefore, the bag body 10 including the arm contact portion 2, the extension portion 3, and the leg rest portion 4 has a Z shape as a whole.

The extending portion 3 includes a first inclined portion 3a, a second inclined portion 3b, a first bending portion 3c, and a second bending portion 3d. The first inclined portion 3a extends from the inner curved portion 2c and is inclined with respect to the first direction D1. The second inclined portion 3b extends from the outer curved portion 2d and is inclined with respect to the first direction D1. The first bending portion 3 c extends from the first inclined portion 3 a to the leg rest portion 4. The second bending portion 3d extends from the second inclined portion 3b to the leg rest portion 4. The length of the extending part 3 in the first direction D1 is, for example, not less than 90 cm and not more than 110 cm, but can be changed as appropriate. The width of the extension part 3 is 15 cm or more and 50 cm or less, for example. Further, the width of the extending part 3 may gradually increase as it goes from the arm contact part 2 to the leg rest part 4, or may gradually decrease as it goes from the arm contact part 2 to the leg rest part 4. .

The first inclined portion 3a and the second inclined portion 3b extend, for example, in a straight line and extend substantially parallel to each other. As an example, the 1st inclination part 3a and the 2nd inclination part 3b incline in the 2nd direction D2 side as it goes to the leg mounting part 4. As shown in FIG. The 1st bending part 3c and the 2nd bending part 3d are curving in circular arc shape, for example. The curvature radius of the first bending portion 3c may be smaller than the curvature radius of the second bending portion 3d, or may be approximately the same as the curvature radius of the second bending portion 3d. The first bending portion 3c and the second bending portion 3d extend while being bent in the third direction D3 toward the leg resting portion 4. Further, the degree of curvature that bends from the extending portion 3 to the leg rest portion 4 is gentler than the degree of curvature that bends from the extending portion 3 to the arm contact portion 2.

The leg rest part 4 has a third end part 4a, a fourth end part 4b, and an inner extension part 4c. The third end 4a is located at the tip in the third direction D3. The fourth end 4b constitutes the other end of the bag 10 in the first direction D1 (the end opposite to the second end 2b). The inner extension 4c extends from the third end 4a to the opposite side of the fourth end 4b and extends from the third end 4a toward the extension 3.

The leg mounting part 4 is made into the shape which tapers as it goes to the 3rd end part 4a from the extension part 3, for example. The width of the leg rest portion 4 in the first direction D1 is narrower than the width of the arm contact portion 2 in the first direction D1. As an example, the third end 4a, the fourth end 4b, and the inner extension 4c are all curved in an arc shape. For example, the curvature radius of the fourth end portion 4b is larger than the curvature radius of the inner extension portion 4c, and the curvature radius of the inner extension portion 4c is larger than the curvature radius of the third end portion 4a. Further, the length of the leg rest portion 4 in the third direction D3 is longer than the length of the arm contact portion 2 in the second direction D2, and may be, for example, 25 cm or more and 55 cm or less.

FIG. 2A and FIG. 2B are cross-sectional views showing the internal structure of the bag body 10. As shown in FIGS. 2A and 2B, the bag body 10 is hollow, and a space S is provided inside the bag body 10. The bag body 10 has a space S that extends from the inside of the arm contact portion 2 to the inside of the leg rest portion 4 through the inside of the extending portion 3, and has a space S that extends over the entire bag body 10. The shape of the body 10 can be freely changed. As an example, the bag body 10 has no contents, and the shape of the bag body 10 is determined by the air in the space S.

As shown in FIG. 2A, the body pillow 1 may include, for example, a side 11a including cotton 11b therein and a cover 11 that accommodates the bag 10. Thus, by accommodating the bag body 10 in the cover 11, the cushioning property of the body pillow 1 can be enhanced and the cover 11 can be easily deformed. The body pillow 1 may be provided with a cover that contains urethane inside and accommodates the bag body 10 instead of the cover 11. That is, urethane may be used instead of the cotton 11b.

As shown in FIG. 2 (b), the body pillow 1 may include a side 12a including a pipe member 12b therein and a cover 12 that accommodates the bag body 10. For example, the pipe material 12b is uniformly accommodated inside the cover 12, and each pipe material 12b has a cylindrical shape. As an example, each pipe member 12b is a polyethylene hollow pipe, but the material of the pipe member 12b may be polystyrene, polyester, polyolefin, or polyurethane. When the bag body 10 is accommodated by the cover 12 having the pipe material 12b, the pillow 1 having a high refreshing feeling can be obtained, and the fluidity of the pipe material 12b is improved to prevent excessive deformation of the cover 12. can do.

As shown in FIG. 1, the dakimakura 1 includes an inflow portion 5 that flows air into the bag body 10 (space S), and an outflow portion that flows air out of the bag body 10 from the inside of the bag body 10. 8. Both the inflow portion 5 and the outflow portion 8 are openable and closable. The inflow portion 5 and the outflow portion 8 are provided at, for example, the end portion of the bag body 10 in the first direction D1, and are both provided on the leg rest portion 4. As an example, the material of the inflow portion 5 and the outflow portion 8 is PVC or polyurethane, but may be the same as the material of the bag body 10 and can be changed as appropriate.

By providing the inflow part 5 and the outflow part 8 on the leg rest part 4, it is possible to suppress the face M3 of the user M from hitting the inflow part 5 or the outflow part 8. However, at least one of the inflow portion 5 and the outflow portion 8 may be provided in the arm contact portion 2. In this case, air can flow into and out of the bag body 10 more easily.

FIG. 3 is an enlarged perspective view of the inflow portion 5. FIGS. 4A, 4 B, and 4 C are cross-sectional views illustrating an example of a state where the inflow portion 5 flows the air A into the bag body 10. The inflow portion 5 is an intake valve that sucks air into the bag body 10. The inflow portion 5 is manually operated, for example. The inflow portion 5 includes an opening 6 that is attached to the opening 10 a of the bag body 10 and has a lid 6 c, and an elastic foam member 7 that is positioned inside the bag body 10 when viewed from the opening 6. Further, the outflow portion 8 includes an opening 6. Since the outflow portion 8 does not have the elastic foam member 7, air flows out of the bag body 10 from the outflow portion 8 by opening the lid 6 c of the outflow portion 8.

For example, the opening 6 is fixed to the opening 10a of the bag body 10 and has a fixed portion 6a having a circulation port 6b through which air A flows, and a lid 6c attached to the fixed portion 6a so as to cover the fixed portion 6a. A string 6d extending from the lid 6c. The fixing portion 6a has a cylindrical shape having a circulation port 6b therein. For example, a male screw 6e that screwes the lid 6c is formed on the outer periphery of the fixing portion 6a. The lid 6c is attached to the fixed portion 6a by the female screw inside the lid 6c being screwed into the male screw 6e of the fixed portion 6a.

The elastic foam member 7 is provided inside the bag body 10 when viewed from the opening 6, and is disposed, for example, at the lower portion of the circulation port 6b. The elastic foam member 7 includes a sponge portion 7 a that can be freely deformed, and a fixing portion 7 b that fixes the sponge portion 7 a inside the bag body 10. The sponge portion 7 a has, for example, a contact surface 7 c that comes into contact with the inner surface 10 b of the bag body 10, and the contact surface 7 c is disposed so as to surround the opening 6.

For example, the contact surface 7 c has a shape that extends long in one direction, which makes it easy to push the elastic foam member 7 from the outside of the bag body 10. As an example, the shape of the contact surface 7c may be oval. The fixing part 7b and the contact surface 7c may be made of plastic or may be made of a flexible material. The fixing portion 7b is, for example, an annular shape surrounding the contact surface 7c, and may be an oval shape.

The sponge portion 7a is, for example, an elastic foam, and is urethane foam as an example. The foamed urethane constituting the sponge part 7a has a property that the surface tension is greatly pulled and is easily deformed. At least a part of the sponge portion 7a is covered with a non-breathable fabric and has a discharge hole communicating with the opening 6 and the space S. The material of the non-breathable fabric is, for example, TPU (thermoplastic polyurethane resin) or PVC (polyvinyl chloride). Air A can flow through the sponge portion 7a, and the air A flows into the space S of the bag body 10 as the sponge portion 7a is compressed and expanded.

Next, a method for inflating the bag body 10 by flowing air A into the space S of the bag body 10 will be described. First, the lid 6c of the inflow portion 5 is opened with the lid 6c of the outflow portion 8 being closed. In this state, since the elastic foam member 7 exists inside the circulation port 6b, the inflow and outflow of air does not occur. Further, when the sponge portion 7a is compressed by pressing the fixing portion 7b or the contact surface 7c with the lid 6c of the inflow portion 5 opened, the sponge portion 7a sucks air A when the sponge portion 7a that has been compressed and deformed expands. At this time, when the sponge portion 7 a sucks air A into the space S of the bag body 10, the bag body 10 expands.

Since the air A enters the space S by repeating the compression and expansion of the sponge portion 7a in this way, the body pillow 1 can be made to have a desired hardness. When the air A is extracted from the space S, the lid 6c of the outflow portion 8 may be opened. Specifically, the air in the space S can be discharged to the outside of the pillow 1 by manually adjusting the degree of screwing of the lid 6c of the outflow portion 8 with respect to the male screw 6e.

Next, the operational effects of the body pillow 1 according to this embodiment will be described in detail. As shown in FIG. 5, in the body pillow 1, an inflow portion 5 that allows air to flow into the space S of the bag body 10, and an outflow portion 8 that causes air to flow out of the bag body 10 from the space S of the bag body 10. Both are provided in the non-breathable bag body 10. Therefore, the inflow part 5 and the outflow part 8 are provided in the bag body 10 itself, and there is no air hose or the like extending from the body pillow 1 to the outside. Therefore, since it can suppress that the part extended outside from the body pillow 1 contacts the user's M body, the situation where the user's M sleeping comfort is impaired can be avoided.

Moreover, in the body pillow 1, the inflow part 5 has the opening part 6 and the elastic foam member 7, and the inflow part 5 is in the space S of the bag body 10 when the elastic foam member 7 which has been compressed and deformed returns. Air inflow into the space S is performed by sucking air. Accordingly, when the compressive deformation is released in a state where the inflow portion 5 is opened and the elastic foam member 7 is compressed and deformed, the elastic foam member 7 flows into the space S of the bag body 10. Therefore, the air can be easily introduced into the space S of the bag 10 by repeatedly compressing and releasing the compression of the elastic foam member 7 after opening the inflow portion 5. Moreover, the air outflow from the inside of the bag body 10 to the outside of the bag body 10 can be easily performed by opening the outflow portion 8.

Therefore, since air can be easily flown into the space S of the bag body 10 and air can flow out of the bag body 10, the dakimakura 1 can be easily expanded and contracted. Accordingly, since the hardness of the body pillow 1 can be easily changed according to the preference of the user M, the body pillow 1 that makes the user M comfortable and can be used comfortably can be obtained.

Moreover, since the air quantity of the bag 10 can be adjusted in a short time by operating the inflow part 5 or the outflow part 8, the shape of the body pillow 1 that easily matches the body shape of the user M can do. Furthermore, the bag 10 (the body pillow 1) does not have any contents. That is, since only the air other than the elastic foam member 7 is provided in the space S of the bag body 10, the shape of the bag body 10 can be further easily changed. Therefore, since the shape of the bag body 10 can be freely and easily deformed according to the body shape or preference of the user M, a comfortable body pillow 1 can be provided. Furthermore, since the bag body 10 can be made compact and lightweight by opening the lid 6c of the outflow portion 8 and extracting the air from the bag body 10, the bag body 10 can be easily carried.

Further, the bag body 10 has a shape extending along the body of the user M of the body pillow 1, and at least one of the inflow portion 5 and the outflow portion 8 may be provided at an end portion of the bag body 10. In this case, at least one of the inflow portion 5 and the outflow portion 8 is provided at the end portion of the bag body 10 so that at least one of the inflow portion 5 and the outflow portion 8 does not easily hit the back M4 or the waist M5 of the user M. be able to. Therefore, it is possible to provide the user M with a more comfortable sleeping comfort.

Further, the inflow portion 5 (elastic foam member 7) is provided at a position shifted from the end of the bag body 10 (for example, the third end portion 4a of the leg rest portion 4). Therefore, as shown in FIG. 4C, the air A sucked by the elastic foam member 7 can be released in the direction of 360 degrees inside the bag body 10, so that the bag body 10 can be efficiently inflated. it can. As a result, the air inflow into the bag body 10 can be performed more rapidly.

Further, as shown in FIG. 5, the bag body 10 includes an arm contact portion 2 and a leg rest portion 4. Therefore, the user M can hang the arm M1 on the arm contact portion 2 and can sandwich the leg rest portion 4 with the leg M2. Therefore, when the arm M1 is placed on the arm contact portion 2 and the leg M2 is placed on the leg rest portion 4, the air inside the bag body 10 moves moderately, and the bag body 10 is brought into the sleeping position of the user M. It is possible to make the shape suitable. Further, the bag body 10 can be properly stretched and stabilized. As a result, since the body of the user M can be stabilized by the bag body 10, the fit of the body of the user M with respect to the bag body 10 can be improved.

Further, since the bag body 10 includes the leg rest portion 4, the leg rest portion 4 can be sandwiched between the legs M2, and therefore, the body line from the waist M5 to the leg M2 can be made closer to the horizontal from the diagonal. Therefore, by placing the leg M2 on the leg rest portion 4, a sleeping posture that is gentle to the waist M5 can be achieved, which contributes to the relief or prevention of back pain. Furthermore, since the bag body 10 includes the arm contact portion 2, the pressure applied to the shoulder M6, the waist M5, and the like of the user M who lies sideways can be dispersed, so that the sideways sleep can be comfortably performed for a long time. . Therefore, in the body pillow 1 according to the present embodiment, it is possible to provide the user M with a comfortable sideways sleep by increasing body pressure dispersibility when lying sideways, so that snoring is reduced and apnea syndrome is achieved. It also contributes to prevention.

(Second Embodiment)
Next, the body pillow 21 according to the second embodiment will be described with reference to FIG. The body pillow 21 is different from the first embodiment in that the body pillow 21 includes a bag body 30 that does not have the leg rest portion 4. The body pillow 21 is used by being held by the arm M1 of the user M, for example. Below, the description which overlaps with 1st Embodiment is abbreviate | omitted suitably. As shown in FIG. 6, the bag body 30 includes an arm contact portion 22, an extending portion 23, and an air inflow / outflow portion 24, and has a rectangular shape (a rectangular parallelepiped shape) that extends long in the first direction D 1 as a whole. It is said that.

The arm contact portion 22 has an end portion 22a, a first bending portion 22b, and a second bending portion 22c. The end 22a is located at one end of the first direction D1 and extends in a direction intersecting the first direction D1. The first curved portion 22b extends from one end of the end portion 22a toward the extending portion 23. The second curved portion 22c extends from the other end of the end portion 22a toward the extending portion 23. The end 22a extends linearly, and the first curved portion 22b and the second curved portion 22c are slightly curved in an arc shape.

The extending portion 23 includes a first extending portion 23a extending linearly from the first curved portion 22b toward the air inflow / outflow portion 24, and a second extending linearly from the second curved portion 22c toward the air inflow / outflow portion 24. And an extending portion 23b. For example, the first extending portion 23a and the second extending portion 23b both extend substantially parallel to each other along the first direction D1.

The air inflow / outflow part 24 is provided at the other end (the end opposite to the arm contact part 22) in the first direction D1. The air inflow / outflow portion 24 includes an end portion 24a extending in a direction intersecting the first direction D1, a third curved portion 24b extending from one end of the end portion 24a to the first extending portion 23a, and the other end of the end portion 24a. And a fourth curved portion 24c extending to the second extending portion 23b. The end portion 24a extends in a straight line, and the third curved portion 24b and the fourth curved portion 24c are slightly curved in an arc shape.

The air inflow / outflow part 24 includes an inflow part 25 for inflowing air into the bag body 30 and an outflow part 28 for outflowing air from the inside of the bag body 30 to the outside of the bag body 30. The inflow portion 25 and the outflow portion 28 are provided, for example, at an end portion in the first direction D1, and are arranged side by side along a direction intersecting the first direction D1. The inflow portion 25 has an opening 26 and an elastic foam member 27, and the outflow portion 28 has an opening 26.

The configurations of the inflow portion 25 and the outflow portion 28 are the same as the configurations of the inflow portion 5 and the outflow portion 8 of the first embodiment, but the shape of the opening 26 is different from the shape of the opening 6. Specifically, the opening 6 opens and closes the bag body 10 by screwing the lid 6c to the male screw 6e, while the opening 26 opens and closes the bag body 30 by attaching and detaching the cap 26a. The configuration of the elastic foam member 27 is the same as that of the elastic foam member 7, for example.

As described above, in the body pillow 21 according to the second embodiment, both the inflow portion 25 that allows air to flow into the bag body 30 and the outflow portion 28 that causes air to flow out from the inside of the bag body 30 to the outside of the bag body 30 are not present. Provided on the breathable bag 30. Therefore, the inflow part 25 and the outflow part 28 are provided in the bag body 30 itself, and there is no air hose or the like extending outside from the body pillow 21. Therefore, it can suppress that the part extended outside from the body pillow 21 contacts the user's M body.

The inflow portion 25 has an opening 26 and an elastic foam member 27. The inflow part 25 sucks air into the bag body 30 when the elastic foamed member 27 that has undergone compression deformation returns to its original shape (the shape before compression), thereby allowing air to flow into the bag body 30. Do. Therefore, by repeating the compression and decompression of the elastic foam member 27, the air can be easily introduced into the bag body 30, so that the same effect as in the first embodiment can be obtained.

As mentioned above, although the embodiment of the body pillow according to the present disclosure has been described, the present invention is not limited to the above-described embodiments, and may be modified without changing the gist described in each claim. That is, the shape, size, number, material, and arrangement of each part of the body pillow can be changed as appropriate without departing from the spirit of the above.

For example, in the above-described embodiment, the body pillow 1 including the bag body 10 including the arm contact portion 2, the extension portion 3, and the leg rest portion 4, the arm contact portion 22, the extension portion 23, and the air inflow / outflow portion 24 are included. The body pillow 21 including the bag body 30 has been described. However, these

body pillows

1 and 21 may be used as pillows on which the head of the user M is placed.

In the above-described embodiment, the bag body 10 having the space S extending from the inside of the arm contact portion 2 to the inside of the leg rest portion 4 through the inside of the extending portion 3 and having no contents has been described. However, the contents may be accommodated inside the bag. For example, contents such as elastic foam may be accommodated only in the arm contact portion 2 and the leg rest portion 4. Moreover, the gusset part may be provided inside the bag body, and the inside of the bag body may be partitioned into a plurality of spaces by the gusset part.

(Example)
Below, the Example of the body pillow 1 of 1st Embodiment is described. In addition, this invention is not limited to the following Example. As shown in FIG. 5, the body pressure dispersion when using the body pillow 1 was measured in the example, and the body pressure dispersion when not using the body pillow was measured in the comparative example.

The measurement results are shown in FIGS. 7 (a) and 7 (b). FIG. 7A shows the measurement result of body pressure dispersion of the example, and FIG. 7B shows the measurement result of body pressure dispersion of the comparative example. Fig.7 (a) and FIG.7 (b) have shown the value of the pressure provided to a bedding in matrix form. FIG. 7A and FIG. 7B show that a high pressure is applied to a dark portion and a low pressure is applied to a light portion.

As shown in FIG. 7B, it can be seen that in the comparative example in which the body pillow 1 is not used, high pressure is applied around the waist M5 and the leg M2 of the user M. On the other hand, as shown in FIG. 7A, in the case of the embodiment using the body pillow 1, the pressure applied to the waist M 5 and the leg M 2 is relaxed, and It can be seen that the body pressure is dispersed.

In addition, an experiment was conducted to measure body pressure dispersion for 10 users M. In this experiment, the maximum body pressure (mmHg), the average body pressure (mmHg), and the ground contact area (cm ² ) to the bedclothes were measured for each user M. As a result, the average value of 10 persons with the maximum body pressure in the example was 28 mmHg, and the average value of 10 persons with the average body pressure in the example was 9 mmHg. On the other hand, the average value of 10 persons of the maximum body pressure in the comparative example was 60 mmHg, and the average value of 10 persons of the average body pressure in the comparative example was 12 mmHg. Therefore, in the Example using the body pillow 1, it turned out that both a maximum body pressure and an average body pressure can be reduced.

As a result of the experiment, the average value of 10 people in the contact area in the example was 3250 cm ² , and the average value of 10 people in the contact area in the comparative example was 2300 cm ² . Thus, in the Example using the body pillow 1, it turned out that the ground-contact area with respect to a bedding can be enlarged. As described above, when the body pillow 1 is used, it has been found that the body pressure dispersibility can be reliably increased by increasing the ground contact area and suppressing the body pressure.
