[0001] The present invention relates to a pillow that eliminates the collision between the shoulder and the pillow of a subject in the lying position and ensures a stable lying position.

Background Art

[0002] FIG. 9 is a top perspective view showing a first conventional pillow (see FIG. 9 of Patent Document 1).

[0003] In FIG. 9, the pillow 1 with a built-in filling member includes an occipital support region 11 located at the center, a cervical support region 12 located on the front side of the occipital support region 11, and temporal support regions 13 and 14 located on the lateral sides of the occipital support region 11 and the cervical support region 12. By sewing at the central stitching point X of the occipital support region 11, the thickness of the central portion of the occipital support region 11 is reduced. On the other hand, the temporal support regions 13 and 14 are convex, that is, the temporal support regions 13 and 14 are higher than the occipital support region 11. In addition, a flange 15 is provided on the outer edge of the temporal support regions 13 and 14 to thicken the temporal support regions 13 and 14. Note that the front-back, left-right, up-down directions are the directions seen from the subject side.

[0004] In the pillow 1 of FIG. 9, the regional division of the pillow 1 can also be adjusted by partitions or the like, and the overall hardness and softness of the pillow 1 can be adjusted by the filling members in each region so that the height of the occipital support region 11 can be accurately maintained, while the height of the temporal support regions 13 and 14 can also be accurately maintained.

[0005] FIG. 10 is a top perspective view showing a second conventional pillow.

[0006] In the pillow 1' of FIG. 10, unlike the pillow 1 of FIG. 9, there is no stitching in the occipital support region 11 and there is no flange 15.

[0007] In the pillow 1' of FIG. 10, the regional division of the pillow 1' is not separated by partitions or the like, and thus it can flexibly accommodate any subject.

[0008] [Patent Document 1] Japanese Patent Publication No. 2021-329 [Overview of the project] [Problems that the invention aims to solve]

[0009] However, with the first conventional pillow 1 shown in Figure 9, as shown in Figure 11, there is a problem in that when subject 2 is lying on their side, subject 2's shoulder 22 collides with the pillow 1, making it impossible to stably maintain the lying position. In other words, when subject 2 lies on their side, an overlapping portion Z1 is created between subject 2's shoulder 22 and the pillow 1. As a result, the edge of the pillow 1 collides with subject 2's shoulder 22, which puts a strain on subject 2's shoulder 22, and the lying position becomes unstable.

[0010] Furthermore, in the second conventional pillow 1' shown in Figure 10, when subject 2 lies on their side, as shown in Figure 12(A), subject 2's shoulder 22 collides with and digs into the pillow 1', resulting in a depression Z2 in the pillow 1' where subject 2's shoulder 22 digs in, as shown in Figure 12(B). This clearly shows that subject 2's shoulder 22 is under strain and the side-lying position is unstable. [Means for solving the problem]

[0011] To solve the above-mentioned problems, the pillow according to the present invention is a pillow having an occipital support region, a cervical support region adjacent to the anterior side of the occipital support region, and first and second temporal support regions adjacent to the occipital support region and the cervical support region, wherein first and second concave shoulder pockets are provided on the anterior side of the first and second temporal support regions. However, the concave shoulder pockets may be provided on only one side of the first and second temporal support regions. [Effects of the Invention]

[0012] According to the present invention, when the subject is lying on their side, the subject's shoulders fit snugly into the concave shoulder pockets of the pillow, eliminating any overlap between the subject's shoulders and the pillow. In other words, there is no collision between the subject's shoulders and the pillow, thus stabilizing the subject's lying-down position. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0014] FIG. 1 is an upper perspective view showing a first embodiment of a pillow according to the present invention.

[0015] In the pillow 1A of FIG. 1, concave shoulder pockets 16 and 17 are provided in front of the temporal support regions 13 and 14 of the pillow 1 in FIG. 9. The concave shoulder pockets 16 and 17 are, for example, V-shaped (or triangular) in top view. Further, the concave shoulder pockets 16 and 17 are sized such that the shoulders of the subject can fit in.

[0016] FIG. 2 is a diagram for explaining the left side lying position of the subject on the pillow 1A of FIG. 1.

[0017] When the subject 2 is in the initial side lying position, a part of the left shoulder 22 of the subject 2 approaches the temporal support region 14 of the pillow 1A and also partly enters the concave shoulder pocket 17 (see FIG. 1). Therefore, at this stage, there is no collision between the shoulder 22 and the pillow 1A.

[0018] Furthermore, when the subject 2 is in the left side lying position, the shoulder 22 of the subject 2 is supported snugly in the concave shoulder pocket 17 (see FIG. 1). Therefore, in this case, the collision between the shoulder 22 and the concave shoulder pocket 17 disappears, and the shoulder 22 is stably supported in close contact with the temporal support region 14 of the pillow 1A. As a result, the side lying position of the subject 2 can be stabilized.

[0019] In addition, in the above-described first embodiment, the concave shoulder pockets 16 and 17 are V-shaped in top view. However, as shown in the first modification example of (A) in FIG. 3, they may be square-shaped in top view, or as shown in the second modification example of (B) in FIG. 3, they may be semi-circular (or conical) in top view.

[0020] Furthermore, in the first embodiment described above, concave shoulder pockets 16 and 17 are provided in each temporal support region 13 and 14. However, if, for example, subject 2 tends to lie on their right or left side only, the concave shoulder pocket may be provided in only one of the temporal support regions 13 and 14.

[0021] Figure 4 is a top perspective view showing a second embodiment of the pillow according to the present invention.

[0022] In pillow 1'A in Figure 4, concave shoulder pockets 16 and 17 are provided on the anterior side of the temporal support areas 13 and 14 of pillow 1' in Figure 10. The concave shoulder pockets 16 and 17 are, for example, V-shaped (or triangular) when viewed from above. The concave shoulder pockets 16 and 17 are also sized to accommodate the shoulders of the subject.

[0023] In Figure 4, as in the first embodiment, when the subject is in a lateral recumbent position, the subject's shoulders partially enter the concave shoulder pockets 16 or 17, and then completely enter. Therefore, the shoulders are stably supported without colliding with the temporal support area 13 or 14 of the pillow 1'A. As a result, the subject's lateral recumbent position can be stabilized.

[0024] In addition, in the second embodiment described above, the concave shoulder pockets 16 and 17 are V-shaped when viewed from above, but they may also be rectangular when viewed from above, as shown in the first modified example in Figure 5(A), or semicircular (or conical) when viewed from above, as shown in the second modified example in Figure 5(B).

[0025] Furthermore, in the second embodiment described above, concave shoulder pockets 16 and 17 are provided in each temporal support region 13 and 14. However, if, for example, a subject tends to lie on their right or left side only, the concave shoulder pocket may be provided in only one of the temporal support regions 13 and 14.

[0026] Figure 6 shows a third embodiment of the pillow according to the present invention, where (A) is a top perspective view and (B) is a rear view.

[0027] In pillow 1B of Figure 6, column units 18 and 19 are provided on the lower side of the temporal support areas 13 and 14 of pillow 1A of Figure 4, and outside the concave shoulder pockets 16 and 17. The column units 18 and 19 act to push up the temporal support areas 13 and 14. In addition, the anterior region of the temporal support areas 13 and 14 protrudes forward from the column units 18 and 19, that is, it forms an overhang shape. In this case, the overhang shape of the column units 18 and 19 and the space between the concave shoulder pockets 16 and 17 and the column units 18 and 19 form arm pockets 18a and 19a. As a result, the subject can more easily assume a stable lateral recumbent position, as will be explained below. Even if the anterior side of the column units 18 and 19 coincides with the anterior side of the temporal support areas 13 and 14, the space between the concave shoulder pockets 16 and 17 and the column units 18 and 19 acts as arm pockets 18a and 19a.

[0028] Furthermore, in pillow 1B shown in Figure 6, a sloping back support area 12' is provided on the front side of the neck support area 12. The back support area 12' gradually thins out from the neck support area 12, which can improve the sleep quality of the subject.

[0029] Figure 7 is a diagram illustrating the left lateral recumbent position of the subject on pillow 1B in Figure 6.

[0030] When Subject 2 is in the initial lateral recumbent position I, as shown in Figure 7(A), a portion of Subject 2's left shoulder 22 approaches the temporal support area 14 of the pillow 1B and also partially enters the concave shoulder pocket 17. Therefore, at this stage, there is no collision between the shoulder 22 and the pillow 1B.

[0031] Furthermore, when Subject 2 moves to a left-sided lateral recumbent position, as shown in Figure 7(B), Subject 2's shoulder 22 is completely contained within the concave shoulder pocket 17. Therefore, in this case, there is no collision between the shoulder 22 and the concave shoulder pocket 17, and the shoulder 22 is stably supported in close contact with the temporal support area 14 of the pillow 1B. At the same time, the shoulder 22 and its arm 23 are contained within the arm pocket 19a formed by the overhang shape of the temporal support area 14 of the pillow 1B. As a result, Subject 2 achieves an even more stable lateral recumbent position.

[0032] Thus, in the third embodiment, the combination of the shoulder pockets 16 and 17 and the column units 18 and 19 (arm pockets 18a and 19a) results in an even more stable lateral recumbent position.

[0033] Figure 8 shows a fourth embodiment of the pillow according to the present invention, where (A) is a top perspective view, (B) is a top view, and (C) is a back view.

[0034] In pillow 1'B of Figure 8, column units 18 and 19 are provided on the back side of the temporal support areas 13 and 14 of pillow 1'A of Figure 4, and outside the concave shoulder pockets 16 and 17. The column units 18 and 19 act to push up the temporal support areas 13 and 14. In addition, the anterior region of the temporal support areas 13 and 14 protrudes forward from the column units 18 and 19, that is, it forms an overhang shape. In this case, the overhang shape of the column units 18 and 19 and the space between the concave shoulder pockets 16 and 17 and the column units 18 and 19 form arm pockets 18a and 19a. As a result, the subject can more easily assume a stable lateral recumbent position, as will be explained below. Note that even if the anterior side of the column units 18 and 19 coincides with the anterior side of the temporal support areas 13 and 14, the space between the concave shoulder pockets 16 and 17 and the column units 18 and 19 acts as arm pockets 18a and 19a.

[0035] In other words, in the initial lateral recumbent position of the subject, a portion of the subject's shoulder approaches the temporal support area 14 of pillow 1'B and also partially enters the concave shoulder pocket 16 or 17. As the subject's lateral recumbent position progresses further, the subject's shoulder is completely contained within the concave shoulder pocket 16 or 17. Therefore, in this case as well, there is no collision between the shoulder 22 and the concave shoulder pocket 16 or 17, and the shoulder 22 is firmly supported in close contact with the temporal support area 13 or 14 of pillow 1'B. At the same time, the shoulder 22 and its arm 23 enter the arm pocket 18a or 19a formed by the overhang shape of the temporal support area 12 or 13 of pillow 1'B. As a result, the subject achieves an even more stable lateral recumbent position.

[0036] Thus, in the fourth embodiment as well, the combination of the shoulder pockets 16 and 17 and the column units 18 and 19 (arm pockets 18a and 19a) results in an even more stable lateral recumbent position.

[0037] Furthermore, the filling material in the first and third embodiments may be made of different materials or the same material for each region, and the filling material in the second and fourth embodiments may be made of one or more flexible materials, such as urethane foam. In addition, other materials besides urethane foam may be used as the filling material, such as pipes, feathers, or mesh members.

[0038] Furthermore, the present invention can be applied to any modification of the above-described embodiments that falls within the scope of obviousness. [Explanation of Symbols]
