bead cushion

Abstract

In addition to improving the cushioning material, a cushion layer that stably maintains the seating pressure around the seat has been constructed to eliminate the extreme floating sensation and the feeling of hitting the bottom. [Solution] A two-layer cushion creation space is formed in the seat area, separated by a cushion body as an independent pressure-resistant layer, and cushion bodies can be added to the cushion creation space to adjust the cushioning properties, or the cushion bodies can be combined to allow the area around the seat area to be freely deformed, while the cushioning material of the bead cushion body is hybridized to improve the extreme floating feeling.

Description

[Technical field]

[0001] The present invention relates to a bead cushion in which resin foam beads are filled into an inner bag, and a fastener member is fastened to wrap the inner bag in a pressed state inside an outer bag, thereby allowing the cushion to change shape freely to suit the intended use. The present invention relates to a cushioning material that is optimal for reducing the feeling of the buttocks hitting the bottom in the seat portion of the bead cushion and for adjusting the freedom of shape change. [Background technology]

[0002] Patent Document 1 states that it provides a bead cushion sofa that can stably form the seat and backrest, and in item (0035) it states that the sheet-like portion 3, which is made of a material such as low-resilience urethane foam and has a thickness of about 1 to 10 cm, is provided in close contact with the lower surface (bottom surface) of the inner bag body 1, thereby restricting the movement of the beads 13 near the bottom surface of the inner bag body 1 and reducing the feeling of the bead cushion sofa hitting the bottom. Although the sheet-like portion 3 does deform, it does not deform as easily as the inner bag body 1, and therefore contributes to maintaining the shape of the inner bag body 1.

[0003] In addition, in (0029) to (0034), the function of the drawstring on the outer bag is described, but this function is to open and close the opening of the outer bag, and the feeling of incongruity is not eliminated by merely changing the floor surface to urethane foam.

[0004] In addition, the feeling of the buttocks hitting the bottom due to the sinking of the seat can be improved by creating a new structure for the seat and improving the cushioning material, which can then be addressed, such as by adjusting the shape and cushioning. To deal with deterioration over time, the general practice is to add additional beads, but this is a difficult task, and there is room for improvement in these maintenance procedures as well.

[0005] Furthermore, although bead cushions offer the freedom to change shape to suit the purpose of use, they have drawbacks such as making it too hot to move around in, making it too much like swimming underwater.

[0006] Patent Document 2 is a document about cushioning materials that aims to provide cushioning materials and related products that can comfortably support the body. However, if the protruding parts collapse due to body pressure, the support effect may not be fully exerted. On the other hand, if the protruding parts are too hard, it may not be possible to use them comfortably. It is a document about cushioning materials that aims to provide cushioning materials and related products that can comfortably support the body. However, it is also required to provide optimal cushioning materials for these cushioning materials. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP 2023-121314 A [Patent Document 2] Patent No. 7442231 [Non-Patent Document 1] Kawakami Sangyo Co., Ltd.'s air bubble cushioning material, registered trademark: PuchiPuchihttps: / / www.putiputi.co.jp / products / 841 [Non-Patent Document 2] Bead cushion manufacturer Yogibohttps: / / yogibo.jp / Summary of the Invention [Problem to be solved by the invention]

[0008] The problem to be solved is that the only way to adjust the shape and cushioning of the bead cushion is to adjust the amount of beads to be filled when the cushioning material of the inner bag deteriorates over time. However, the technology described in Patent Document 1 has a bottom-raised sheet-like part with a thickness of about 10 cm, made of low-resilience urethane foam. In addition, the technology described in Patent Document 2 may not be able to fully exert its support effect if the protruding parts collapse due to body pressure, and may not be able to be used comfortably if the protruding parts are too hard. Although this is an improvement on the cushioning material, there is still room for further improvement.

[0009] Therefore, as an improvement over conventional bead cushions, the present invention aims to solve the problem that, by filling a one-piece inner bag with beads and wrapping them in a one-piece outer bag, when the air escapes from the inner and outer bags around the seat area where weight is concentrated, the beads move to areas other than the seat area, creating a feeling of the seat hitting the bottom, and further, the moved beads are scattered to areas other than the seat area and compressed, causing them to cling to the body and become floating, resulting in a feeling of restricted movement. [Means for solving the problem]

[0010] In order to solve the above problems, the present invention provides a cushion layer that absorbs the seat pressure concentrated on the seat, and an independent cushion layer is constructed to stably hold the seat pressure on the seat and its surroundings, and a cushion layer is placed on the cushion layer. The cushion body (C) is packed in an independent bag to prevent it from scattering outside the seat. The present invention is embodied as a cartridge type cushion body in which a new cushion material is packed in an inner bag of various shapes.

[0011] In this way, the seat periphery between the outer bottom surface of the inner bag, which is packed in a tucked state inside the outer bag, and the inner bottom surface of the outer bag, A space (C) is provided via a cushion body (C1), and a plurality of cushion bodies (C2 to C6) are added to the space (C). This makes it possible to adjust the cushioning, and by changing the arrangement and combination, it is also possible to adjust the shape and height around the seat. By arranging the cushion body that serves as the armrest in an appropriate position, it can easily be turned into a sofa. It can also be built into the bead cushion body in advance, or used when adding more beads due to deterioration over time, etc., and the most important feature of this product is that the functional effects described above can be obtained in ways that go beyond just adding more beads due to deterioration over time, etc. Effect of the Invention

[0012] The present invention provides a bead cushion with a two-layered cushion structure with a cushion body provided as a base around the seat of the bead cushion body (creative space), and by adding multiple cushion bodies to the cushion layer, it is possible to eliminate the deterioration of the beads over time, provide a comfortable sitting experience, and eliminate the feeling of hitting the bottom, and it is possible to further improve and evolve the cushion body created by each individual. The cushion material is a hybrid of resin foam beads and air bubble cushioning material, which is light and easy to handle, and provides a comfortable cushioning feel, and these are packed in an inner bag of any shape and are replaced in a cartridge type, making maintenance work such as refilling and disposal easy, and it has the advantage of being able to be further improved by responding to various requests and suggestions such as ideas from users.

[0014] Preferred embodiments of the present invention will be described below with reference to the drawings. Note that the embodiments shown below are merely examples of methods for embodying the technical ideas of the present invention, and are not limited to the following, and various modifications can be made within the technical scope described in the claims.

[0015] The bead cushion body B of this embodiment is provided with a cushion creation space A consisting of two upper and lower cushion layers, with a cushion body C1 as a base, around the seat area C between the outer bottom surface of the inner bag body A filled with beads and the inner bottom surface of the outer bag body B that contains the inner bag body A. Each component of the cushion body C created and assembled in the cushion creation space A will be described in detail below with reference to Figures 1 to 7. Note that the directions of up, down, left, and right used in the following description refer to the directions when the drawing is viewed from the front, and the cushion creation space will be referred to as the creation space A.

[0016] The creative space A of the present invention refers to the seat periphery U between the inner bag A filled with foam beads and the outer bag B that contains the inner bag A. The seat periphery U is a portion formed of a cushion layer with a two-layer structure, upper and lower, via a cushion body C1 made by stacking air bubble cushioning materials and packing them into the inner bag A1, and the cushion layer is configured as a cushion body C. The cushion body C provided in the creative space A will be explained below.

[0017] In Fig. 1, the left side of the figure is the bead cushion body B of this embodiment, which is a perspective view showing a very common bead cushion. The right side of Fig. 1 is a development view showing the rear side of the bead cushion body B, in which the rear side of the outer bag body I is opened by a fastener K provided on the rear side of the outer bag body I and the seat area U between the outer bottom surface of the inner bag body A and the inner bottom surface of the outer bag body I in a lifted state. EXAMPLES

[0018] FIG. 2 is an explanatory diagram showing an example of the cushion body C1. In FIG. 2, the cushion body C1 is a cartridge type replacement that can be easily replaced by folding the foam cushioning material and packing it into the inner bag body A1, and making the cushion bodies C1 to C6, etc. detachable by using a hook-and-loop fastener D at appropriate places on the front and back surfaces. The method of attachment and detachment is not limited, but the hook-and-loop fastener D can be either a sewn type or an adhesive type. As the cushioning material, foam beads, cotton, etc. can also be used, but the foam cushioning material is optimal because it is lightweight, moderately deformable, and easy to maintain the cushioning force in a stable state. In addition, in the case of the foam cushioning material, the inner bag body A1 does not need to stretch, so it is preferable to wrap it in a non-stretchable fabric and fix it by penetrating the important points with a hook-and-loop tape. EXAMPLES

[0019] 3 is a perspective view showing an example of the cushion bodies C2, C3, C4, C5, and C6. In FIG. 3, the cushion bodies C2, C3, C4, C5, C6, . . . are previously Stuffed with foam beads or bubble wrap The cartridge type replacement allows users to freely choose the cushioning level by adjusting the weight and shape as desired.

[0020] In the cushion bodies C2 and C3, the cushioning force can be fixed by wrapping the air bubble cushioning material tightly or loosely in a roll and stuffing it into a non-stretchy fabric, making it an ideal cushioning material that has a wide range of elasticity changes and can be easily adapted to the purpose of use. Also, when filling with foam beads, The fabric of the bag It is preferable to use a stretchable fabric, and the same is true for cushion bodies C4, to C6. Like the hook-and-loop fastener D on C2 and C3, it is preferable to provide it on the back side of C4, C5, and C6 and fix it to the required position of the cushion body C1 around the seat part of the bead cushion main body B. EXAMPLES

[0021] 4 is an explanatory diagram showing an example of assembly of the cushion body C. The cushion body C provided around the seat part C between the inner bag body A and the outer bag body B may be fixed by bonding the cushion bodies C2, C3, C4, C5, C6, ... to the cushion body C1 as a base with a hook-and-loop fastener D.

[0022] Furthermore, since the cushioning material, shape, and size are all optional, if it is desired to maintain a stable cushioning force for a long period of time, it is preferable that the cushioning material for the cushion bodies C2 to C5 provided at the lower part of C1 be bubble cushioning material, and for the cushion bodies C2 to C5 provided at the upper part of C1, which is relatively free from gravity, it is better to select cushion bodies whose cushioning material is foam beads. Furthermore, in order to make the shape similar to that of the bead cushion main body B, it is preferable to select taking into consideration the shape and arrangement of the cushion body C, and it is preferable to arrange it in a shape that follows the inner outer periphery of the outer bag body I, as this allows the outer periphery shape and height of the seat periphery U to be maintained stably. EXAMPLES

[0023] Fig. 5 is an explanatory diagram showing an example of a state in which the cushion body C6 is arranged. Fig. 5 shows a state in which the male or female surface of the hook-and-loop fastener D1 of the cushion body C6 is adhered and fixed to the male or female surface of the hook-and-loop fastener D1 of the cushion body C1. The cushion body C with the cushion body C6 is pushed in from the rear seat periphery U and arranged in a position between the front outer bag body I and the inner bag body A. The tip of the cushion body C6 may be fixed with the hook-and-loop fastener D, or may be fixed with a string, or may be folded over the cushion body C, or may be rolled up around the knees. In addition, when filling and refilling beads due to deterioration over time, etc., instead of filling the inner bag body A, Filling the bag with cushioning material It is recommended to replace or add a new cartridge type.

[0024] In this way, the sticking of the beads to the body can be improved by using a mixture of foam beads and bubble cushioning material as the cushioning material for the inner bag body A, or by placing a sheet-like cushion body C6 made of bubble cushioning material between the inside of the front outer bag body B and the outside of the inner bag body A.

[0025] FIG. 6 shows bubble wrap. EXAMPLES

[0026] Fig. 7 is a diagram showing bubble cushioning material 1 and resin foam beads 2. To make the cushioning material to be stuffed into inner bag A and / or inner bag A1, the resin foam beads and bubble cushioning material are cut into small disks measuring several centimeters to tens of centimeters and mixed together. The bubble cushioning material is lightweight and has a surface that can withstand pressure, so it has good cushioning properties with the foam beads. By mixing it appropriately, a hybrid effect can be achieved as a cushioning material, and a cushioning feel that does not cling to the skin can be obtained, which is preferable. [Industrial Applicability]

[0027] It also improves on drawbacks such as the feeling of hitting the bottom due to the sinking of the seat, and the discomfort of being unable to move due to the heat of swimming underwater. Furthermore, it clearly indicates countermeasures against deterioration over time, and can also be applied to hybrid cushioning materials. [Explanation of symbols]
