Description

[Technical field]

[0001] The present invention relates to a pillow for relieving pressure on the cheek when a subject is in a recumbent position. [Background technology]

[0002] Conventionally, in pillows molded with a mold using urethane or the like, the left and right temporal support areas are flat (see Patent Document 1). Therefore, when a subject turns over in a lateral position from side to side, pressure is applied from the temporal support area to one cheek.

[0003] In the above-mentioned pillow, in order to reduce pressure from the temporal support areas to the cheeks when turning over in sleep, it is also possible to provide a recess in each temporal support area to reduce pressure on the cheeks. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2021-329 A (Patent No. 7063474) Summary of the Invention [Problem to be solved by the invention]

[0005] However, when a recess is provided in each temporal support region, the pressure of the temporal support region on the cheek when lying down is reduced, but there is a problem in that a gap is generated between the cheek and the bottom of the recess, making the body unstable. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the pillow of the present invention has an occipital support area, a neck support area adjacent to the front side of the occipital support area, and a right head support area and a left head support area adjacent to the front area within the occipital support area and the right and left sides of the neck support area, and the right head support area and the left head support area respectively comprise a soft filling member area located in the center of the right head support area and the left head support area and having a soft filling member, and a hard filling member area located around the soft filling member area and having a hard filling member harder than the soft filling member, and each hard filling member area is C-shaped, U-shaped or ring-shaped when viewed from above. Effect of the Invention

[0007] According to the present invention, when the subject lies down, the cheek of the subject is supported by the temporal support region, and at that time, the strain of the soft filling member region is greater than that of the hard filling member region, so the soft filling member region is depressed. As a result, the pressure on the cheek is reduced, and no gap is generated between the cheek and the temporal support region, resulting in stability. [Brief description of the drawings]

[Figure 7] FIG. 5 is a diagram for explaining the operation of the pillow in FIGS. 1 to 4. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Fig. 1 shows an embodiment of the pillow of the present invention, (A) is an upper perspective view, (B) is a top view, Fig. 2 is a front perspective view of Fig. 1, Fig. 3 is a right perspective view of Fig. 1, and Fig. 4 is a rear perspective view of Fig. 1. Note that the front direction (below the head), rear direction (above the head), right direction, left direction, upper direction, and lower direction in Figs. 1 to 4 are directions seen from the subject.

[0010] As shown in Figures 1 to 4, the pillow is composed of an upper pillow unit 1 and a lower pillow unit 2 provided on a part of the lower surface of the upper pillow unit 1. The upper pillow unit 1 is a sewn product filled with a first filling member such as a pipe, polyester cotton, etc., excluding a hard filling member described later, and the lower pillow unit 2 is a molded product made of a second filling member such as urethane, etc., or may be a non-molded product.

[0011] The upper pillow unit 1 has a first occipital support region 11, a neck support region 12 adjacent to the front side of the first occipital support region 11, a right head support region 13 and a left head support region 14 adjacent to the right and left sides of the first occipital support region 11 and the neck support region 12, and a second occipital support region 15 on the rear side of the first occipital support region 11. The first occipital support region 11, the neck support region 12, the right head support region 13, the left head support region 14, and the second occipital support region 15 are partitioned by a partition cloth 16. The first occipital support region 11 and the second occipital support region 15 form one occipital support region, but in particular, the first occipital support region 11 is referred to as a front region in the occipital support region, and the second occipital support region 15 is referred to as a rear region in the occipital support region.

[0012] As shown in Figs. 1 to 4, in the upper pillow unit 1, the right head support region 13 has a soft filling member region 13a provided in the center of the right head support region 13 and having a soft filling member, for example, the same member as the first filling member described above, and a hard filling member region 13b provided around the soft filling member region 13a and having a hard filling member harder than the soft filling member, for example, the same member as the second filling member described above. The soft filling member region 13a and the hard filling member region 13b are also partitioned by a partition cloth 16. On the other hand, the left head support region 14 has a soft filling member region 14a provided in the center of the left head support region 14 and having a soft filling member, for example, the same member as the first filling member described above, and a hard filling member region 14b provided around the soft filling member region 14a and having a hard filling member harder than the soft filling member, for example, the same member as the second filling member described above. The soft filling member area 14a and the hard filling member area 14b are also partitioned by a partition cloth 16. The bottom of the soft filling member area 13a and the bottom of the soft filling member area 14a are supported by the lower pillow unit 2. The size of the soft filling member area 13a and the soft filling member area 14a is large enough to fully support the right or left cheek of the subject, but does not include the right or left forehead and the right or left jaw of the subject, and therefore the right or left forehead and the right or left jaw of the subject are supported by the hard filling member area 13b and the hard filling member area 14b. This reduces the pressure on the cheeks of the subject when the subject turns from the supine position to the lateral position.

[0013] 1 to 4, the front region of the right head support region 13 and the front region of the left head support region 14 of the upper pillow unit 1 protrude forward from the lower pillow unit 2. In other words, the lower pillow unit 2 is smaller than the upper pillow unit 1. This makes it easier for the subject's right or left shoulder to move toward the lower pillow unit 2 when the subject turns over from the supine position to the lateral position.

[0014] Next, the hard filling member constituting the hard filling member regions 13b and 14b in FIGS. 1 to 4 will be described with reference to FIGS.

[0015] 5 shows a method for manufacturing a two-stage hard filling member. That is, a C-shaped upper urethane 51 shown in (A) and a C-shaped lower urethane 52 shown in (B) are prepared, and as shown in (C), the C-shaped upper urethane 51 and the C-shaped lower urethane 52 are stored in an inner bag 53 to prevent the soft filling member from being mixed in, thereby completing a two-stage hard filling member made of a combined two-stage urethane with an inner bag.

[0016] 6 shows a method for producing a hard filling member with a single layer structure. That is, a C-shaped urethane 61 shown in (A) is prepared, and as shown in (B), the C-shaped urethane 61 is stored in an inner bag 62 for preventing the soft filling member from being mixed in, thereby completing a hard filling member with a single layer structure made of a single layer urethane with an inner bag.

[0017] Incidentally, the hard filling member in FIG. 5 and FIG. 6 is C-shaped to facilitate thermal deformation, but it may be U-shaped or ring-shaped.

[0018] The operation of the pillow of FIGS. 1 to 4 using the hard filling member of FIGS. 5 and 6 will be described with reference to FIG.

[0019] When subject P turns over from the supine position to the lateral position to the right side, the right cheek of subject P fits into the soft filling member area 13a of the right head support area 13. At that time, the right forehead, right occipital region, and right jaw of subject P are supported by the hard filling member area 13b of the right head support area 13. At this time, since the distortion of the soft filling member area 13a is larger than the distortion of the hard filling member area 13b, the soft filling member area 13a is depressed, and no gap is generated between the right cheek of subject P and the soft filling member area 13a, resulting in stability.

[0020] When the subject P is in a lateral position, the shoulders of the subject P go under the right head supporting region 13 or the left head supporting region 14 of the upper pillow unit 1 where the lower pillow unit 2 is not present. As a result, the subject can smoothly turn over from the supine position to the lateral position.

[0021] A method for manufacturing the pillow shown in FIGS. 1 to 4 using the hard filling members shown in FIGS. 5 and 6 will be briefly described.

[0022] First, an upper pillow unit 1 is prepared, which is divided by a partition cloth 16 into a first occipital support region 11, a neck support region 12, a soft filling material region 13a and a hard filling material region 13b of the right head support region 13, a soft filling material region 14a and a hard filling material region 14b of the left head support region 14, and a second occipital support region 15.

[0023] Next, the lower pillow unit 2 is sewn to the bottom of the upper pillow unit 1. In this case, the lower pillow unit 2 can be opened and closed by a zipper.

[0024] Next, the two-stage urethane with inner bag of FIG. 5 or the one-stage urethane with inner bag of FIG. 6 is inserted into the hard filling member region 13b of the right head support region 13 and the hard filling member region 14b of the left head support region 14.

[0025] Next, a first filling material, such as polyester cotton, is filled from the filling material filling port of each divided area except for the hard filling material areas 13b and 14b of the upper pillow unit 1. This completes the first occipital support area 11, the neck support area 12, the soft filling material area 13a of the right head support area 13, the soft filling material area 14a of the left head support area 14, and the second occipital support area 15.

[0026] Finally, the filling member filling openings in each region of the upper pillow unit 1 are closed.

[0027] Furthermore, the pillow described above is a two-layer pillow, consisting of an upper pillow unit 1 made of sewn material and a lower pillow unit 2 made of a molded product, but it may also be a one-layer pillow made of sewn material with beads, pipes, polyester cotton, etc. as filling materials.

[0028] Furthermore, the present invention can be applied to any obvious modifications of the above-described embodiments. [Explanation of symbols]
