Description

[Technical Field]

[0001] The present invention relates to a pillow. [Background technology]

[0002] Pillows formed by combining components have been proposed in the past. For example, the pillow described in Patent Document 1 is composed of a base core member with multiple recesses of different depths formed on its upper surface, cells containing padding and arranged to fit into each of the recesses, and a bag-shaped member covering the base core member and cells. The recesses are provided in the occipital support portion, the left and right temporal support portions that support the left and right sides of the head in a lateral position, and the portion that supports the cervical vertebrae. The base core member is covered with a bag-shaped member, and a height adjustment member for adjusting the height of the pillow is placed on the underside of the base core member, and the entire body is covered with a cover. A occipital support pad may be detachably provided on the cell that fits into the occipital support portion. Furthermore, a functional member with a fragrance-emitting function or a sound-emitting function can be installed between the recesses provided in the base core member and the cell that fits into the recesses.

[0003] According to this document, the pillow can be easily adjusted to suit individual preferences by adjusting the overall height of the pillow and the amount of filling in each cell formed in the bag-shaped member. Furthermore, the filling in the cells in the recesses formed in the pillow easily moves with changes in posture, so even when the pillow deforms in response to sleeping positions such as supine and lateral positions, the individual cells are independently configured, resulting in minimal change in the overall height of the pillow. Furthermore, because the base core member and the bag-shaped member are integrated, the pillow does not shift or distort while in use. Furthermore, the bag-shaped member and filling can be removed, allowing each part to be washed, so the pillow can always be kept clean. Furthermore, the document states that using functional members with fragrance or sound-emitting functions can help users sleep better thanks to the fragrance or sound.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-82590 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the pillow described in Patent Document 1 is expected to have the following problems: Because the cells are directly fitted into recesses formed on the front side of the pillow, a boundary is created between the base core member and the cell, which causes an extreme difference in sensation experienced by the user at the boundary, resulting in a poor feel when using the pillow.

[0006] An object of the present invention is to solve the problems of the prior art and to provide a pillow that creates partially different sensations of use without causing extreme changes in sensation at the boundaries. [Means for solving the problem]

[0007] A pillow according to one aspect of the present invention comprises a pillow body with a recess on its underside and an attachment member that can be attached to the recess. This allows the pillow to create different sensations when used between the pillow body and the attachment member attached to the recess. Furthermore, because the front side of the attachment member is covered by the pillow body, extreme variations in the sensation experienced by the user between the pillow body and the attachment member can be suppressed.

[0008] The pillow may also have the recesses disposed on both the left and right sides of the center of the pillow body, in which case the pillow can provide different sensations of use at the center and the left and right sides of the pillow body. [Brief explanation of the drawings]

[0010] Hereinafter, a pillow 1 embodying the present invention will be described with reference to the drawings. The description of the embodiment of the invention and the drawings referred to are used to explain the technical features that can be adopted by the present invention. The present invention is not limited to these. The configurations shown in the drawings are merely illustrative examples and are not intended to limit the present invention.

[0011] <Pillow 1 explanation> With reference to FIGS. 1 to 7, the configuration of a pillow 1 according to an aspect of the present invention will be described using a pillow 1a of a first embodiment as an example. As shown in FIG. 1, the pillow 1 is substantially rectangular in plan view from the front side. When a person lies flat with their head facing upward, the back of the head rests on the central portion 4, and the shoulders rest on the left and right portions 5 and 6 adjacent to the central portion 4. The corners are formed in an R-shape. The direction perpendicular to the left-right direction is the up-down direction, with the neck side defined as the lower side and the head side defined as the upper side. The distance between the front and back sides is defined as the height direction. As shown in FIGS. 1 to 3 and 5 to 7, the pillow 1 includes a pillow body 2 having a recess 12 on its back side and an attachment member 3 detachable from the recess 12. The recesses 12 are located on both the left and right sides of the center of the pillow body 2. For example, the length of the central portion 4 in the left-right direction is 196 mm, and the left and right portions 5 and 6 are each 225 mm.

[0012] Next, the shape of the front side of the pillow 1 will be described. As shown in Fig. 1, a neck recess 13 is formed at the lower end of the central portion 4 toward the upper side. The neck recess 13 is a recess formed so that the pillow body 2 supports the back of the head and neck when the user is lying flat. As shown in Figs. 2 to 4, the pillow body 2 has a central recess 11 formed from the front side of the central portion 4 toward the back side. As shown in Fig. 3, the central recess 11 is shaped so that it is most recessed near the center in the left-right direction and gradually expands toward both the left and right sides. Also, as shown in Fig. 4, it is shaped so that it is most recessed near the center in the up-down direction and gradually expands toward the upper and lower sides.

[0013] Next, the recess 12 will be described with reference to Figs. 3 to 5. The recess 12 is formed in the pillow body 2 by being recessed from the back side of each of the left side part 5 and the right side part 6 toward the front side. As shown in Fig. 6, the recess 12 is formed in the left-right direction adjacent to the central part 4, and is formed so as to extend to both ends in the left-right direction. As shown in Fig. 3, the thickness dimension of the pillow body 2 forming the recess 12 is approximately the same thickness across the left-right direction. As shown in Fig. 5, the thickness dimension of the parts forming the recess 12 in the left side part 5 and the right side part 6 is largest at approximately the center in the vertical direction and gradually decreases toward the upper and lower sides.

[0014] Next, the mounting member 3 will be described. The mounting member 3 is molded into a predetermined shape and is detachable from the recess 12. The pillow body 2 and the mounting member 3 are made of urethane foam, for example. For example, the pillow body 2 is molded, and the mounting member 3 is slab molded. As shown in FIG. 5, the mounting member 3 has approximately the same height dimension from the bottom to the top in the vertical direction. Also, as shown in FIG. 3, the shape of the upper side in the height direction is formed to match the shape of the recess 12 formed in the pillow body 2. Alternatively, it may be formed into a flat plate.

[0015] As shown in Fig. 3, the attachment member 3 can be attached from the back side of the pillow body 2. Also, as shown in Fig. 7, when the pillow body 2 is stored in the cover 10, the attachment member 3 can be inserted from each of the insertion openings 9 on the left and right sides of the pillow body 2.

[0016] Furthermore, the attachment member 3 may be harder than the pillow main body 2, or the attachment member 3 and the pillow main body 2 may have the same hardness. Furthermore, the left side part 5 and the right side part 6 of the attachment member 3 may have the same hardness, or the left and right sides may have different hardnesses. As an example of hardness, the pillow main body 2 has a hardness of 30N to 150N, and the attachment member 3 has a hardness of 30N to 200N. The attachment member 3 is set harder than the pillow main body 2 within this hardness range. The hardness is measured according to the measurement standard JIS K 6400-2D method (25% compression).

[0017] <Effects of Pillow 1> The configuration of the pillow 1 described above provides the following effects. As shown in FIG. 3 and other figures, the pillow 1 can create different sensations of use between the pillow main body 2 and the attachment member 3 attached to the recess 12. Furthermore, because the front side of the attachment member 3 is covered by the pillow main body 2, extreme changes in sensation experienced by the user between the pillow main body 2 and the attachment member 3 can be suppressed. In other words, the pillow 1 can suppress extreme changes in sensation of use when the user lies on the center portion 4 and when the user lies on the left portion 5 or right portion 6. If the attachment member 3 were exposed on the front side, the user would feel a sudden change in firmness during use if there was a large difference in firmness between the attachment member 3 attached to the recess 12 and the pillow main body 2. In contrast, the pillow 1 has the effect of cushioning the change in firmness between the pillow main body 2, which is covered by the front side, and the attachment member 3 attached to the recess 12.

[0018] 1 and other figures, the pillow 1 has recesses 12 arranged on both the left and right sides of the center of the pillow body 2, so that it is possible to create a different feeling of use between the center and the left and right sides of the pillow body 2. That is, it is possible to create a different feeling of use when the user lies flat on the center part 4 and when the user lies on his / her side on the left part 5 or right part 6.

[0019] Furthermore, the pillow 1 solves the following problems. If the attachment member 3 were not molded but were in the form of a bag-shaped cell with stuffing sealed inside, the work would be time-consuming and there would be the problem that the stuffing would spill out during the work. Furthermore, the inner material of the cell changes with changes in posture, so there is the problem that it is difficult to maintain a constant shape. In contrast, as shown in Figure 7, the pillow 1 has an attachment member 3 that is molded into a predetermined shape and can be attached and detached to the pillow body 2, so the state of the pillow 1 adjusted by the attachment member 3 can be stably maintained. Because the attachment member 3 is molded into a predetermined shape, the attachment work is easy.

[0020] Furthermore, if the attachment member 3 is harder than the pillow body 2, the amount of sinking is reduced in the left and right parts 5 and 6. This makes it easier to sleep on your side and turn over in your sleep. Furthermore, the pillow 1 can be made so that the hardness of the attachment members 3 differs between the left and right sides to suit users who tend to sleep on their side in one direction, for example.

[0021] Furthermore, since the attachment member 3 is detachable from the pillow body 2, attachment members 3 of different hardness can be flexibly attached at the manufacturing site. In other words, pillows 1 with attachment members 3 of different hardness can be easily manufactured.

[0022] Furthermore, the attachment members 3 are replaceable by the user. The user can attach an attachment member 3 of the hardness they prefer to the pillow body 2 and use it. For example, it is assumed that the pillow 1 may come with multiple different attachment members 3, or that the attachment members 3 may be sold as options.

[0023] <<Detailed explanation of pillow 1 and its effects>> Next, the detailed configuration of the pillow 1 will be described with reference to Figures 1 to 7, and the effects of each configuration will be described. In addition to the configurations already described, the pillow 1 may also have the following detailed configurations. The pillow 1a of the first embodiment will be described as an example.

[0024] <About the height and sinking amount of pillow 1> 2 to 5, the height and sinking amount of the pillow 1 will be described. When the mounting member 3 is attached to the recess 12, the pillow 1 has a height dimension greater in the left side part 5 and the right side part 6 than in the height dimension in the center part 4. Furthermore, when a predetermined load is applied from the front side, the sinking amount is greater in the center part 4 than in the left side part 5 and the right side part 6.

[0025] A detailed description will be given below. As shown in Fig. 3, when the mounting member 3 is attached to the recess 12 of the pillow 1, the heights of the left side portion 5 and the right side portion 6 are between dimensions t12 and t14. The minimum dimension t12 is the boundary with the central portion 4 in the left-right direction. As shown in Figs. 3 and 5, the maximum dimension t14 is near the center in the up-down direction and within a predetermined range from the left and right ends in the left-right direction. As shown in Fig. 5, the left side portion 5 and the right side portion 6 bulge near the center in the up-down direction and the height dimensions become smaller toward the upper and lower sides. For example, the dimension t12 is 48 mm and the dimension t14 is 60 mm.

[0026] The height at the central portion 4 ranges from the minimum dimension t11 to dimensions t12 and t13. The minimum dimension t11 is near the center in the left-right and up-down directions, as shown in Figures 3 and 4. As shown in Figure 3, the thickness gradually increases from near the center in the left-right direction, reaching dimension t12 at the boundary between the pillow body 2 and the left and right portions 5 and 6. As shown in Figure 4, the thickness gradually increases from near the center in the up-down direction, reaching dimension t13. Dimension t13 is located at a predetermined distance from each of the lower and upper ends toward the center, as shown in Figure 4. For example, the minimum dimension t11 is 30 mm, and dimension t13 is 50 mm.

[0027] As shown in Figure 3 etc., the central part 4 has a larger proportion of the height dimension occupied by the pillow body 2 in the height direction than the left part 5 and the right part 6. In other words, the central part 4 is formed only by the pillow body 2, while the left part 5 and the right part 6 are formed by combining the attachment member 3 and the pillow body 2. If the attachment member 3 is harder than the pillow body 2, the amount of sinking when a predetermined load is applied from the front side will be larger in the central part 4 than in the left part 5 and the right part 6.

[0028] <Effect of pillow 1 height and sinking amount> The configuration of the pillow 1 described above provides the following effects. The left side part 5 and the right side part 6 have a greater height dimension than the center part 4, so it is possible to stabilize the flat lying state. In addition, the amount of sinking when a predetermined load is applied from the front side is greater in the center part 4 than in the left side part 5 and the right side part 6, so it is easy to sleep on your side and turn over in your sleep.

[0029] <Regarding the edge 7 of the pillow 1> Next, the edge portion 7 formed on the pillow 1 will be described with reference to Figures 5 and 6. The edge portion 7 is formed on the lower end of the pillow body 2. The edge portion 7 forms a wall from the back side to the front side. The recess 12 is formed from the edge portion 7 toward the upper side in the vertical direction. As an example, the vertical dimension L of the pillow body 2 is 310 mm, and the edge portion 7 is formed in a range of 47 mm to 50 mm from the lower end. The dimension of the edge portion 7 from the lower end is arbitrary, but it is desirable that it be a dimension that feels as hard as the pillow body 2 when a person's shoulders touch it. With this configuration, when a person lies flat, both shoulders come into contact with the edge portion 7 as shown in Figure 1.

[0030] <Effect of the edge 7 of the pillow 1> The above-described configuration provides the following effects: The pillow body 2 has the edge portion 7 formed at the lower end, so the portion that comes into contact with the person's shoulders can have the same feel as the center portion 4. Even if the attachment member 3 is hard, the portion that comes into contact with the shoulders has the same hardness as the pillow body 2 and is therefore softer than the attachment member 3, improving the feel of use.

[0031] <Explanation of thickness of pillow body 2> Next, the thickness dimension of the pillow body 2 will be described. The thickness dimension of the pillow body 2 at the portion where the recess 12 is formed is equal to or smaller than the thickness dimension at the central recess 11. As shown in Figs. 3 to 5, the minimum thickness dimension t11 at the central portion 4 of the pillow body 2 is equal to or larger than the maximum thickness dimension t2 at the portion where the recess 12 is formed. For example, the minimum thickness dimension t11 is 30 mm, and the maximum thickness dimension t2 is 30 mm. In other words, the thickness dimension at the central portion 4 of the pillow body 2 is equal to or larger than the thickness dimension at the portion where the recess 12 is formed.

[0032] <Effect of thickness of pillow body 2> According to the configuration described above, the pillow 1 has a predetermined thickness in the central portion 4, so the user can feel the hardness of the pillow body 2. In the left and right portions 5 and 6, the thickness dimension of the pillow body 2 is equal to or less than the thickness dimension of the central portion 4, so the influence of the hardness of the pillow body 2 is reduced, and a user lying on the front side can feel the hardness of the attachment member 3. In other words, if the attachment member 3 is harder than the pillow body 2, the user can feel the hardness of the left and right portions 5 and 6 more strongly than that of the central portion 4.

[0033] <Explanation of thickness of mounting member 3> Next, the relationship between the attachment member 3 and the thickness dimension of the pillow body 2 that forms the recess 12 will be described with reference to Figures 3 and 5. The maximum thickness dimension t3 of the attachment member 3 is equal to or greater than the maximum thickness dimension t2 of the portion of the pillow body 2 where the recess 12 is formed. As an example, as shown in Figures 3 and 5, the maximum thickness dimension t3 of the attachment member 3 is 30 mm, and the maximum thickness dimension t2 of the pillow body 2 that forms the recess 12 is 30 mm. In other words, the maximum thickness dimension t3 of the attachment member 3 is equal to or greater than the maximum thickness dimension t2 of the pillow body 2 that forms the recess 12.

[0034] <Effect of thickness of mounting member 3> According to the configuration described above, when a user lies on the pillow 1 from the front side, the left side part 5 and the right side part 6 are more likely to get the feel of use that the attachment member 3 has than the feel of use that the pillow main body 2 has. In other words, if the attachment member 3 is harder than the pillow main body 2, the user can feel the hardness of the left side part 5 and the right side part 6 more strongly than that of the center part 4.

[0035] <Difference between the pillow 1a of the first embodiment and the pillow 1b of the second embodiment> Next, the differences between the pillow 1a of the first embodiment and the pillow 1b of the second embodiment will be explained. Figures 1 to 7 show the pillow 1a, and Figures 8 to 10 show the pillow 1b. Note that Figures 2 to 4 and 7 are common to the pillow 1a and pillow 1b. The pillow 1a has an edge portion 7 formed on the lower side in the up-down direction of the pillow body 2, and an edge portion 8 formed on the upper side. As shown in Figure 7, the edge portions 7 and 8 act as guides in the up-down direction when the mounting member 3 is attached with the pillow body 2 housed in the cover 10. Note that the effect of the edge portion 7 has already been explained.

[0036] In contrast, the pillow 1b has an edge 7 formed only on the lower side in the vertical direction. As shown in Fig. 7, the edge 7 serves as a guide on the lower side when attaching the attachment member 3 with the pillow body 2 stored in the cover 10. Note that Fig. 8 corresponds to Fig. 1, Fig. 9 corresponds to Fig. 6, and Fig. 10 corresponds to Fig. 5. In each figure, except for the part where the edge 8 is absent, the rest is the same.

[0037] Pillow 1a includes a pillow body 2a, a recess 12a, and an attachment member 3a, while pillow 1b includes a pillow body 2b, a recess 12b, and an attachment member 3b. The attachment member 3b of pillow 1b is longer upward in the vertical direction compared to the attachment member 3a of pillow 1a due to the absence of edge portion 8. Furthermore, the recess 12b is formed wider in the vertical direction compared to the recess 12a due to the absence of edge portion 8. Therefore, the attachment member 3b of pillow 1b can be formed larger than the attachment member 3a of pillow 1a. Therefore, when the attachment member 3b is harder than the pillow body 2b, the user can feel the hardness of the left side portion 5 and the right side portion 6 stronger than that of the center portion 4. Pillows 1a and 1b similarly achieve the effects of the pillow 1 already described. [Explanation of symbols]
