Description

[Technical Field]

[0001] This invention relates to a foam pillow. [Background technology]

[0002] Patent Document 1 aims to provide a pillow shaped to allow for easy turning over in sleep without shifting the pillow during sleep. The pillow in Patent Document 1 has a central area where the head rests on the pillow when lying on one's back, two areas on both sides where the head can be rotated 90 degrees to the left and right and then rested on the pillow when lying on one's side, and a surface connecting these three areas to allow for smooth head rotation. If these three areas and the connecting parts are shaped at a height that does not strain the posture of the neck and shoulders when turning over in sleep, the pillow will provide a comfortable sleep by allowing for smooth turning between lying on one's back and on one's side.

[0003] The purpose of Patent Document 2 is to provide a pillow that is comfortable for both back and side sleeping, taking into consideration the user's freedom to turn over in their sleep. The pillow in Patent Document 2 consists of a bag body with three stuffing storage compartments, and stuffing to be stuffed into each of the stuffing storage compartments of the bag body. By stuffing the left and right stuffing storage compartments with more stuffing than the central stuffing storage compartment, the height of the bag body when in use is configured so that the center is lower and the left and right are higher.

[0004] Patent Document 3 aims to provide a pillow that has good breathability, heat dissipation, and cushioning properties, allowing users to sleep comfortably without their heads getting sticky with sweat, even on hot, uncomfortable summer nights, ensuring a good night's sleep. The pillow in Patent Document 3 is composed of a pillow material 2, a three-dimensional lattice space material placed on top of the pillow material, and a knitted pillow cover that covers the entire material, with the pillow material being made of materials that can be used to make pillows, such as low-resilience polyurethane foam, feathers, cotton, or short pieces of plastic straw pipe, and the three-dimensional lattice space material 4 being made by weaving a large number of plastic threads together to maintain a communicating air layer.

[0005] [Patent Document 1] Utility Model Registration No. 3157545 [Patent Document 2] Utility Model Registration No. 3072529 [Patent Document 3] Japanese Patent Application Laid-Open No. 2005-152480 Summary of the Invention [Problem to be solved by the invention]

[0006] Patent Documents 1 and 2 are able to accommodate changes between supine and lateral positions due to turning over in bed, but do not consider breathability, while Patent Document 3 takes breathability into consideration but does not consider turning over in bed. Furthermore, in all of Patent Documents 1 to 3, it is difficult to encourage the rotation of the head when turning over to the lateral position, or to assist the rotation of the neck by rebounding toward the center when returning to the supine position.

[0007] Therefore, the purpose of this invention is to provide a foamed resin pillow that supports the neck, deforms in accordance with the movement of the head when turning over in sleep, assists the rotation of the neck in accordance with the turning over movement, and at the same time has high breathability. [Means for solving the problem]

[0008] The present invention has been made to solve the above problems, and comprises a pillow body, This foamed resin pillow is characterized by having a plurality of short-side slits arranged in the short direction at specific intervals in the longitudinal direction from the top surface of the pillow body downward, and the short-side slits have a U-shape when viewed from the front.

[0009] According to the pillow, the multiple short-side slits in the dogleg shape increase breathability, and by adjusting the density of the pillow body, it is possible to encourage the head to tilt when turning to a side-lying position, and to assist the rotation of the neck when returning to a supine position by the rebound force toward the center. The dogleg slits can encourage both turning to a side-lying position and turning to a supine position.

[0010] The lateral slits are preferably provided symmetrically in front view, which makes it easy to turn over in either direction.

[0011] It is preferable that the pillow further includes a second short-side slit extending downward from the top surface of the pillow body in the short-side direction in the center of the pillow body, the second short-side slit having a downward arrow shape with a straight portion and a V-shaped tip when viewed from the front. This configuration further improves breathability and adjusts the sinking of the head, making it easier to turn over in sleep.

[0012] It is preferable that the depths of the lateral slits are different from each other. This configuration allows the head to sink more easily, making it easier to turn over in sleep.

[0013] It is preferable that the depth of the lateral slits is such that the depth of the slits near the center is deeper than the depth of the slits near the left and right ends. This configuration can encourage the initial movement of turning over and assist the rotation to the lateral position.

[0014] It is preferable that the depth of the lateral slits is such that the slits near the center are deeper than the slits near the left and right ends, and the depth of the second lateral slit is deeper than the depth of the lateral slit. This configuration can encourage the initial movement of turning over and assist the rotation to the lateral position.

[0015] It is preferable that the specific intervals of the lateral slits in the longitudinal direction are different. This configuration can assist the rotation of the head and further increase the ease of turning over in sleep.

[0016] The L-shaped slits in the transverse direction are preferably set to open from the left and right ends in the longitudinal direction toward the center, so that the crushed foam resin rebounds toward the upper center, assisting neck rotation and making it easier to turn over in bed.

[0017] It is preferable to provide a plurality of longitudinal slits that intersect the lateral slits at right angles and are provided in the longitudinal direction at specific intervals in the lateral direction from the upper surface downward. This configuration improves breathability while also adjusting the sinking of the back of the head, and the three-dimensional movement of the pillow body 2 makes it easier to turn over in sleep.

[0018] It is preferable that the depths of the longitudinal slits are different. This configuration further improves breathability, adjusts the sinking of the back of the head, and increases the ease of turning over in sleep due to the three-dimensional movement of the pillow body 2.

[0019] It is preferable that the front and back sides are at different heights, allowing the user to choose which side is closer to the neck depending on their physique and preferences. [Effects of the Invention]

[0020] According to the present invention, it is possible to provide a foamed resin pillow that supports the neck while deforming in accordance with the movement of the head, assists in both turning from the supine position to the lateral position and from the lateral position to the supine position, and at the same time improves breathability.

[0024] As shown in FIG. 1 etc., the pillow 1 preferably further includes a cover that covers the pillow body 2, but this is omitted here.

[0025] As shown in Figures 2 and 3, the short-side slits 3a to 3f are provided symmetrically with respect to the central vertical line C, and are bent like a V-shape in front view. The V-shape is set so that it opens from the left and right ends toward the center in the longitudinal direction Y. In addition, a specific interval W is provided in the longitudinal direction Y between the short-side slits 3a and 3b, 3b and 3c, 3d and 3e, and 3e and 3f. 3a , W 3b , W 3c , W 3dThe second short-side slit 4 is provided in the center of the pillow body 2 so as to overlap with the central vertical line C, and is shaped like a downward arrow with a straight portion and a V-shaped tip when viewed from the front. There are also specific intervals W in the longitudinal direction Y between the short-side slit 3c and the second short-side slit 4, and between the second short-side slit 4 and the short-side slit 3d. 4a , W 4b Since the two are symmetrical, the specific interval W 4a and a specific interval W 4b are the same intervals.

[0026] The lateral slits 3a to 3f preferably have different specific intervals between them in one side region divided by the central vertical line C, and here, the specific intervals are set so as to become wider from the left and right ends toward the center. In other words, the specific intervals W 3a and W 3d than a specific interval W 3b and W 3c Since the left and right sides are symmetrical, the specific interval W 3a and W 3d , specific interval W 3b and W 3c The widthwise slits 3a to 3f are equal in the widthwise direction in the region on one side divided by the central vertical line C, and the widths D 3a , D 3b , D 3c , D 3d , D 3e , D 3f Here, it is preferable that the depths D in the Z direction of the lateral slits 3a to 3f are different. 3a ~D 3f The depth of the slits near the center is set deeper than the depth of the slits near the left and right ends, and as a result, the height of the upper part of the L-shape is smaller in the slits near the left and right ends than in the slits near the center. 3a , and D 3f , depth D 3b and D 3e , depth D 3c and D 3dThe depth D4 of the second lateral slit 4 is the same as the depth D of the lateral slits 3c and 3d closest to the center. 3c , D 3d is set deeper than

[0027] As shown in FIG. 4, the longitudinal slits 5a, 5b, and 5c have respective depths D 5a , D 5b , D 5c In addition, between the longitudinal slits 5a and 5b, and between the longitudinal slits 5b and 5c, a specific interval W is set in the short direction X. 5a , W 5b is placed, and a specific interval W 5a , W 5b may be at different intervals, but in this embodiment they are set to the same intervals. [Example]

[0028] The pillow body 2 uses low-resilience urethane foam manufactured by Sun Living Co., Ltd. The hardness of the low-resilience urethane foam is 30 Newtons to 90 Newtons. The density of the low-resilience urethane foam is 30D to 90D. The resilience of the low-resilience urethane foam is 1% to 15%. The dimensions of the pillow 1 are length (short side direction X) 400mm, width (longitudinal direction Y) 600mm, front side height H1 (thickness direction Z) 100mm, and back side height H2 (thickness direction Z) 80mm. The short side slits 3a to 3f have a width of 10mm and are spaced at specific intervals W 3a is 55mm, W 3b is 80mm, W 3c is 80mm, W 3d The depth D of the slits 3a to 3f in the transverse direction is 55 mm. 3a is 52mm, D 3b is 58mm, D 3c is 72mm, D 3d is 72mm, D 3e is 58mm, D 3f The width of the second lateral slit 4 is 10 mm at the straight portion and 10 mm at the tip of the L-shaped portion. 4a , W 4bThe width of the longitudinal slits 5a to 5c is 10 mm, and the specific interval W 5a is 34mm, W 5b The depth D of the longitudinal slits 5a to 5c is 34 mm. 5a is 24mm, D 5b is 36mm, D 5c The angle of the short-side slits 3a to 3f and the angle of the short-side slit at the tip of the second short-side slit 4 are 90 degrees.

[0029] According to the pillow 1 of this embodiment, the dogleg-shaped lateral slits 3a-3f, which are provided symmetrically in a front view, improve breathability, while at the same time adjusting the density of the pillow body 2, encouraging the head to tilt when turning to a lateral position and assisting the rotation of the neck when returning to a supine position by the repulsion toward the center. Furthermore, the longitudinal slits 5a-5c improve breathability and adjust the sinking of the back of the head, allowing the three-dimensional movement of the pillow body 2 to make turning over easier.

[0030] The slits 3a to 3f in the shorter side direction are provided symmetrically in front view, so that it becomes easy to turn over in either direction.

[0031] The second lateral slit 4 provided in the center further improves breathability and adjusts the sinking of the head, making it easier to turn over in bed.

[0032] Depth D of slits 3a to 3f in the transverse direction 3a ~D 3f Since the cushion has different sizes, it is possible to adjust the sinking of the head and make it easier to turn over in bed.

[0033] Depth D of slits 3a to 3f in the transverse direction 3a ~D 3fThe depth D4 of the second short-side slit 4 provided in the center is deeper than the depth D of the short-side slits 3c and 3d closest to the center. 3c , D 3d It is deeper than the standard, which encourages the initial movement of turning over and assists rotation to the lateral position, making it even easier to turn over.

[0034] The specific interval W in the longitudinal direction Y of the lateral slits 3a to 3f 3a and W 3b , W 3c and W 3d are different, and the specific interval W 3a is a specific interval W 3b Narrower, specific interval W 3d is a specific interval W 3c Because it is narrower, it encourages movement from the lateral position back to the center and assists rotation back to the supine position, making it even easier to turn over.

[0035] The L-shaped slits 3a to 3f in the shorter direction are oriented so that they open toward the center, so that the crushed foam resin rebounds toward the upper center, assisting in the rotation of the neck when returning from a lateral position to a supine position, making it even easier to turn over in bed.

[0036] Depth D of longitudinal slits 5a to 5c 5a ~D 5c Since the difference in the thickness of the pillow body 2 makes it possible to further improve breathability, adjust the sinking of the back of the head, and increase the ease of turning over in sleep due to the three-dimensional movement of the pillow body 2.

[0037] By making the front and back sides different heights, you can choose which side is closer to your neck depending on your body type and preferences.

[0038] Although the preferred embodiment of the present invention has been described above in detail, the present invention is not limited to the above embodiment, and various modifications and alterations are possible within the scope of the present invention as set forth in the claims of the utility model registration.
