Description

[Technical Field]

[0001] The present invention relates to cushions and cushion sets. [Background technology]

[0002] Traditionally, support devices such as pillows, lumbar supports, and cushions have been used to reduce the concentration of body pressure during sleep or rest. However, most of these support devices only address specific areas (head, neck, lower back, etc.) and are not designed to optimally support multiple areas at the same time, such as the neck, lower back, and heels, where body pressure tends to concentrate.

[0003] In addition, most conventional pillows have a single shape and lack the ability to flexibly fit to differences in human body size (adults, women, children). Furthermore, on hard floors or in outdoor environments, strong pressure is likely to be placed on the heel, often causing pain and numbness. Therefore, there is a demand for a support device that can simultaneously accommodate multiple areas, be adjustable in shape to fit differences in body size, and improve body pressure distribution.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-245970 Summary of the Invention [Problem to be solved by the invention]

[0005] Many conventional pillows and cushions are designed to support specific areas such as the head or lower back, making it difficult to simultaneously and adequately support multiple areas where body pressure tends to concentrate, such as the neck, lower back, and heels. Furthermore, because most conventional products have a single shape, it is not possible to adjust the fit to accommodate differences in body size, such as for adults, women, and children, and they have not been able to fully alleviate the various discomforts caused by poor posture and concentrated body pressure while sleeping (headaches, stiff shoulders, cold shoulders, lower back pain, sudden lower back pain, strain from turning over in bed, heel pain, numbness).

[0006] On the other hand, Patent Document 1 discloses a multi-purpose cushion that can be used as a pillow, armrest, backrest, etc., but this document aims to improve support by deforming the shape of a single cushion, and does not disclose structures such as a structure in which numerous acupressure protrusions are formed on the surface of the cushion to distribute body pressure, a configuration in which three identical cushions are placed respectively at the neck, waist, and heel areas to provide three-point support, or an opening / closing adjustment mechanism that allows the cushion to be used in an open or closed position depending on the user's physique.

[0007] Therefore, the cushion in Patent Document 1 cannot solve the problem of simultaneously distributing body pressure in multiple parts of the body while stabilizing the overall posture during sleep, and has the problem of not being able to fully reduce pain, numbness, chills, and strain from turning over in bed in the neck, lower back, and heels, regardless of the environment (bed, tatami, hard floor, outdoors).

[0008] This invention was proposed in light of the above points, and aims to provide a cushion that simultaneously supports the neck, lower back, and heels, effectively disperses concentrated body pressure, and can flexibly accommodate differences in body size. [Means for solving the problem]

[0009] In order to solve the above problems, the cushion of the present invention has a cushion body with multiple protrusions formed on its surface, and the cushion body has a first member and a second member that are foldably connected to each other via a connecting portion, and the first member and the second member can be opened and closed via the connecting portion.

[0010] In order to solve the above problems, the cushion set of the present invention has a cushion body with multiple protrusions formed on its surface, and the cushion body has a first member and a second member that are foldably connected to each other via a connecting part, and the set includes three cushions of the same structure in which the first member and the second member can be opened and closed via the connecting part, and the cushions are placed on the user's neck, waist, and heels, respectively, for use. [Effects of the Invention]

[0011] According to the embodiment of the present invention, it is possible to provide a cushion that simultaneously supports the neck, lower back, and heels, effectively disperses the concentration of body pressure, and flexibly adapts to differences in body size.

[Figure 5] FIG. 1 is a diagram showing a state in which a three-piece set of cushions 1 according to this embodiment is stored in a portable storage backpack. DETAILED DESCRIPTION OF THE INVENTION

[0013] The present invention will be described in detail with reference to the drawings. When the same reference numerals are used in multiple drawings, the description will be omitted.

[0014] Figure 1 shows the external structure of a cushion with acupressure protrusions for body pressure distribution 1 according to this embodiment. Cushion 1 is made of a flexible and resilient urethane material, and the main body has a two-piece structure consisting of one half 1a (first member) and one half 1b (second member). Half 1a and half 1b are connected so as to be able to open and close by a stitching line, an integrally molded flexible section, a flexible hinge, or the like.

[0015] The surface of the cushion 1 is provided with a number of acupressure protrusions (acupressure points) 1c at equal intervals, which are designed to alleviate localized concentration of body weight, distribute body pressure, ensure breathability, and provide a relaxing effect.The acupressure protrusions 1c can also be called body pressure distribution protrusions or massage protrusions.

[0016] The cushion 1 also has a Velcro® 2 to keep the cushion 1 open and closed, and the two halves 1a and 1b can be opened or closed depending on the user's physique.

[0017] FIG. 2 is a diagram showing a structure in which the cushion 1 according to this embodiment can be used in an open state. The cushion 1 has two halves 1a and 1b connected in a foldable manner, and can be used in the open state as shown in FIG. 2. This structure allows for flexible adjustment, such as opening it to increase the width for children or users with small builds, and folding it to obtain an appropriate thickness and reaction force for adults. Furthermore, the opening and closing structure allows the cushion 1 to be folded for storage in a space-saving manner when carrying it around.

[0018] FIG. 3 is a diagram showing the opening and closing structure of the cushion 1 according to this embodiment, viewed from the underside. Half 1a and half 1b are connected via a connecting portion 1d, such as a stitching line, a flexible portion, or a flexible hinge, and this connection allows for opening and closing. As shown in FIG. 3, Velcro® 2 is arranged on half 1a and half 1b to secure the cushion in the folded state and also to hold it in the open state as needed. This allows the user to adjust the shape of the cushion 1 to suit their physique and sleeping position.

[0019] 4(A) is a diagram showing the appearance of cushion 1 when used by an adult. When used by an adult, cushion 1 is used in a closed state (with one half 1a and the other half 1b overlapping each other), and body pressure is efficiently distributed by placing it on the desired areas such as the neck, lower back, and heels.

[0020] 4(B) is a diagram showing the appearance when a woman or child uses the cushion 1. Since women and children tend to have smaller physiques, using the cushion 1 in an open position increases the contact area with the body, allowing it to fit more naturally to the body.

[0021] Cushion 1 can also be configured as a three-piece set using three cushions of the same type. By appropriately placing cushions 1 in three areas - the neck, lower back, and heels - the user can prevent the concentration of body pressure, maintain posture, reduce pain, and prevent chills. As all cushions are the same type, it has the advantages of being easy to manufacture, offering a high degree of freedom in placement, and being easy to replace for each area.

[0022] Use as a neck pillow (neck N) When cushion 1 is placed around the neck N as shown in Figures 4(A) and (B), the acupressure protrusions 1c fit into the minute irregularities around the neck and shoulders, providing support without leaving any gaps, which can have the effects of reducing headaches, alleviating stiff shoulders, preventing cold shoulders (no gaps are created and cold air does not flow in), and reducing and preventing strain on the neck.

[0023] Use as a lumbar pillow (lower back) When cushion 1 is placed on the lower back W, it maintains the natural curve of the lower back (S-curve) and prevents the lower back from unnaturally straightening. This has the effect of reducing lower back pain, preventing sudden lower back pain, and reducing the strain caused by turning over in bed. The acupressure protrusions 1c gently support the entire lower back, preventing body pressure from being concentrated at one point, reducing strain even when lying down for long periods of time.

[0024] Use as a heel pillow (heel H) By placing the cushion 1 in the heel area H, it is possible to reduce heel pain, numbness and ankle strain, and prevent reduced blood flow due to pressure, even on hard floors, wooden floors, or in outdoor environments such as camping. In particular, the acupressure protrusions 1c diffuse the contact pressure on the heel, significantly reducing the discomfort that occurs when directly touching a hard floor.

[0025] The cushion 1 of the present invention provides the following overall effects by using it according to the part of the body. -Improved body pressure distribution -Stabilizes sleeping posture - Pain relief (headaches, stiff shoulders, lower back pain, heel pain) -Relief of numbness - Reduces the burden of turning over in bed Prevents cold - Comfortable for use on hard floors and outdoors Fig. 5 shows the three-piece cushion set 1 according to this embodiment stored in a portable storage backpack. Because this cushion 1 is made of urethane material and is lightweight, as shown in Fig. 5, by storing the three-piece set for the neck, waist, and heels together in the storage backpack, it can be easily carried when traveling or doing outdoor activities (camping, etc.). The storage backpack has one or two shoulder straps and can be carried on one or both shoulders, which has the advantage of reducing the burden on the user when carrying it around on a daily basis.

[0026] <Summary> According to the present invention, a cushion body with multiple acupressure projections on its surface is constructed from two detachably connected components, providing an adjustable cushion that can be opened and closed to suit the user's physique. Furthermore, by using three identical cushions and placing them in three areas—the neck, lower back, and heels—the body pressure generated in these areas can be effectively distributed, reducing headaches, stiff shoulders, cold shoulders, lower back pain, sudden lower back pain, strain from turning over in bed, heel pain, and numbness. This invention makes it possible to provide a cushion that can flexibly accommodate differences in the user's physique and ensure comfortable support not only indoors but also on hard floors and in outdoor environments.

[0027] Although the present invention has been described above by showing specific examples according to preferred embodiments of the present invention, it is apparent that various modifications and changes can be made to these examples without departing from the broad spirit and scope of the present invention as defined in the claims. In other words, the details of the examples and the accompanying drawings should not be construed as limiting the present invention. [Explanation of symbols]
