Description

[Technical Field]

[0001] The present invention relates to a bead cushion that has the freedom to change shape to suit the purpose of use by filling an inner bag with resin foam beads, fastening a fastener member, and encasing the inner bag in a pressed state in an outer bag, and 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 adjusting the freedom to change shape. [Background technology]

[0002] Patent Document 1 states that it provides a bead cushion sofa that can stably form the seat and backrest portions, 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 underside (bottom) of the inner pouch body 1, thereby restricting the movement of the beads 13 near the bottom of the inner pouch body 1 and reducing the feeling of the bead cushion sofa touching the bottom. Although the sheet-like portion 3 can deform, it does so less easily than the inner pouch body 1, and therefore contributes to maintaining the shape of the inner pouch body 1.

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

[0004] In addition, the feeling of bottoming out caused by the seat sinking can be improved by creating a new structure for the seat and improving the cushioning material, which can also allow for adjustments to the shape and cushioning.In dealing with deterioration over time, the usual method 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 their shape to suit the purpose of use, they have drawbacks such as being too hot and unable to move, making them feel like they are swimming in water.

[0006] Patent Document 2 states that its purpose is to provide a cushioning material and related products that can comfortably support the body. However, if the protrusions collapse due to body pressure, the support effect may not be fully achieved. On the other hand, if the protrusions are too hard, it may become difficult to use comfortably. Although this is a document about cushioning materials, it is necessary to identify the optimal cushioning material for these cushioning materials as well. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Publication No. 2023-121314 [Patent Document 2] Patent No. 7442231 [Non-Patent Document 1] Kawakami Sangyo Co., Ltd.'s air bubble wrap registered trademark "Puchi-Puchi" 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 stuffed into the inner pouch when the cushioning material deteriorates over time. However, the technology described in Patent Document 1 includes a raised sheet-like portion about 10 cm thick made of low-resilience urethane foam. The technology described in Patent Document 2 may not fully support the user if the protruding portions collapse due to body pressure, and may also be uncomfortable to use if the protruding portions are too hard. While 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 eliminate the problem that, by filling beads into a one-piece inner bag and wrapping them in a one-piece outer bag, when the air in the inner and outer bags escapes around the seat area where weight is concentrated, the beads move outside the seat area, causing the seat to feel like it has hit the bottom, and further, the moved beads are scattered to the small areas outside the seat area and compressed, causing them to cling to the body and become floating, making it difficult to move. [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 maintain the seat pressure on the seat and its surrounding area. The cushion body placed in this cushion layer is packed into an independent inner bag so that it does not disperse outside the seat, and can be replaced at any time.The present invention provides a cartridge-type cushion body in which new cushioning materials are packed into inner bags of various shapes.

[0011] In this way, a two-layer cushion creation space with an upper and lower layer structure is created around the seat area between the outer bottom surface of the inner bag body, which is compressed and wrapped inside the outer bag body, and the inner bottom surface of the outer bag body, via a unique cushion body.The cushioning can be adjusted by adding multiple cushion bodies to the cushion creation space, and the shape and height around the seat area can be adjusted by changing the arrangement and combination.By placing the cushion body that serves as the armrest in an appropriate position, it can easily be made into a sofa.It can also be built into the bead cushion body in advance, or used when adding beads due to deterioration over time, etc.The most important feature of the above-mentioned functional effects is that they can achieve effects that go beyond just adding beads due to deterioration over time, etc. [Effects of the Invention]

[0012] The present invention provides a bead cushion with a two-layer 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 prevent the beads from deteriorating over time, provide a comfortable sitting experience, and eliminate the feeling of hitting the bottom, while also allowing for the cushion bodies to be further improved and evolved through individual creative efforts.The cushion material is a hybrid of resin foam beads and air bubble wrap, which makes it light, easy to handle, and provides a comfortable cushioning feel, and these are packed into an inner bag of any shape and replaced as a cartridge, making maintenance such as refilling and disposal easy, and has the advantage of being able to be further improved by responding to various requests and ideas from users.

[0014] Preferred embodiments of the present invention will be described below with reference to the drawings. Note that the following embodiments 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 of the claims.

[0015] The bead cushion body B of this embodiment is provided with a cushion creation space A consisting of two cushion layers, upper and lower, with a cushion body C1 as a base, located around the seat area C between the outer bottom surface of an inner bag body A filled with beads and the inner bottom surface of an outer bag body B that houses the inner bag body A. Below, each component of the cushion body C created and assembled in the cushion creation space A will be described in detail 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 drawings are viewed from the front, and the cushion creation space will be referred to as 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 houses 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 C1 made by stacking bubble cushioning materials and stuffing them into the inner bag A1, and this cushion layer is configured as a cushion C. The cushion C provided in the creative space A will be explained below.

[0017] In Fig. 1, the left side view is a perspective view of the bead cushion body B of this embodiment, which is a very ordinary bead cushion. The right side view 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 with a fastener K provided on the rear side of the outer bag body I and lifted up, showing the seat area C between the outer bottom surface of the inner bag body A and the inner bottom surface of the outer bag body I. [Example]

[0018] FIG. 2 is an explanatory diagram showing an example of cushion body C1. In FIG. 2, cushion body C1 is made by folding foam cushioning material and stuffing it into inner bag body A1. Hook-and-loop fasteners D are used on the front and back surfaces of the cushion body C1, C6, etc., making them detachable and easily replaceable cartridge-type replacements. While the attachment and detachment method is not limited, hook-and-loop fasteners D can be either sewn or adhesive. While foam beads and cotton can also be used as cushioning materials, foam cushioning is ideal because it is lightweight, deforms moderately, and easily maintains a stable cushioning force. Furthermore, foam cushioning does not need to stretch; instead, inner bag body A1 can be wrapped in non-stretch fabric and secured in place with hook-and-loop tape. [Example]

[0019] Fig. 3 is a perspective view showing examples of cushion bodies C2, C3, C4, C5, and C6. In Fig. 3, cushion bodies C2, C3, C4, C5, C6, etc. are replaceable cartridges in which foam beads and / or bubble cushioning material are pre-filled in an inner bag body A1, and the amount and shape can be freely selected to provide a wide range of cushioning properties.

[0020] In cushions C2 and C3, the cushioning force can be fixed by tightly or loosely wrapping the bubble cushioning material into a roll and stuffing it into a non-stretchy fabric, making it ideal as a cushioning material with a wide range of elasticity and easy to adapt to various uses. When stuffing foam beads, it is recommended to use a stretchable fabric for the inner bag A1, and the same applies to cushions C4, C5, and C6. Like the hook-and-loop fastener D of C2 and C3, it is also recommended to use a hook-and-loop fastener D on the back of C4, C5, and C6, which can be fixed to the required position on the cushion C1 and installed around the seat part C of the bead cushion main body B. [Example]

[0021] 4 is an explanatory diagram showing an example of assembling the cushion body C. The cushion body C provided around the seat part C between the inner pouch body A and the outer pouch body B may be formed by adhering and fixing cushion bodies C2, C3, C4, C5, C6, etc. to a base cushion body C1 with hook-and-loop fasteners D.

[0022] Furthermore, since the cushioning material, shape, and size are optional, if it is desired to maintain stable cushioning force for a long period of time, it is recommended that the cushioning material for the cushion bodies C2 to C5 provided at the bottom of C1 be bubble cushioning material, and that the cushion bodies C2 to C5 provided at the top of C1, which are relatively free from gravity, be cushion bodies with foam beads as their cushioning material.Furthermore, to create a shape similar to that of the bead cushion main body B, it is recommended to take into consideration the shape and arrangement of the cushion body C when selecting, and it is preferable to arrange it in a shape that follows the inner outer periphery of the outer bag body I, as this will allow the outer shape and height of the seat periphery U to be maintained stably. [Example]

[0023] Fig. 5 is an explanatory diagram showing an example of the state in which the cushion body C6 is arranged. Fig. 5 shows the state in which the male or female surface of the hook-and-loop fastener D1 on the cushion body C6 is adhered and fixed to the male or female surface of the hook-and-loop fastener D1 on the cushion body C1. The cushion body C with the cushion body C6 is preferably pushed in from the rear seat periphery (C) and positioned between the outer pouch body (I) and the inner pouch body (A) on the front side. The tip of the cushion body C6 may be fixed with the hook-and-loop fastener D, or with a string, or may be folded over the cushion body C, or rolled up around the knees. Furthermore, when refilling beads due to deterioration over time, it is preferable to replace or add a cartridge type cushioning material filled in the inner pouch body (A) rather than filling the inner pouch body (A).

[0024] In this way, the clinging 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. [Example]

[0026] Figure 7 shows bubble cushioning material 1 and resin foam beads 2. To create 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 from a few centimeters to 10-odd centimeters and mixed together. Bubble cushioning material is lightweight and has a surface that can withstand pressure, so it provides good cushioning properties when combined with the foam beads. By mixing it in the right amount, a hybrid effect can be achieved as a cushioning material, providing a cushioned feel that does not cling to the skin. [Industrial Applicability]

[0027] It also improves on drawbacks such as the feeling of hitting the bottom due to the seat sinking, and the feeling of being unable to move due to the heat caused by swimming underwater.It also clearly shows countermeasures for dealing with deterioration over time, and can be applied to hybrid cushioning materials.
