[Conventional technology]

Conventional pneumatic cushions consist of two layers of non-breathable sheets and their peripheral edges By sealing the air bag to make an air bag and attaching a tree inside, the entire air bag becomes a beer bag. This prevents it from expanding too much into a barrel shape and creates an almost flat cushion shape. The structure (Reference 1) consists of a number of log-shaped air strips arranged parallel to each other. The cushion is shaped like a raft, and a sealing part is formed at the boundary between each air strip. and the sealing portion extends to both edges of the cushion (Reference 2); In addition, there is a method such as that disclosed in Utility Model Application Publication No. 57-152059, which was disclosed by the present inventor in a previous application. Two non-breathable sheets are stacked and their peripheral edges are sealed, and the cushion body is There are some well-known ones in which circular fixing parts that do not expand are formed at multiple locations (Reference 3). It is.

[Problem that the idea aims to solve]

However, Reference 1 shows that air movement occurs inside the cushion when air is sealed. The jitsu causes shaking and makes it uncomfortable, especially when you put your weight on the cushion. In some cases, the cushion surface and the human body come into close contact, resulting in poor air circulation and stuffiness. Because of this, it makes you feel uncomfortable if you use it for a long time. In addition to being uncomfortable due to rumbling shaking, it also has the same drawbacks as Reference 1. In addition, References 1 to 3 show that when you put your weight on the cushion, your body moves a lot. It can't be supported at points, so it distributes your weight evenly and makes you feel comfortable. It did not have any special effects such as providing a massage effect on the body. It is.

0004 The present invention has been made to solve the various problems mentioned above.

[0005]

[Means to solve the problem]

Therefore, the present invention was developed by stacking two non-breathable sheets made of synthetic resin and covering the periphery of the sheets. A large number of circular sealed portions of approximately the same shape are formed over the entire surface of the air-impermeable sheet. At least one ventilation circuit is provided by providing communication parts between the required circular sealing parts. Form the seat with a valve for introducing and retaining air at any point in the ventilation circuit. Equipped on top, it forms a completely new pneumatic cushion.

[0006]

[Effect]

Now, when air is blown through the valve, everything on the same ventilation circuit as the valve will Air is filled into the circular sealed part through the communication part, and a large number of approximately spherical air sacs are created. It is formed. If two ventilation circuits are formed, two valves By blowing air into the air, spherical air sacs are formed on each of the two ventilation circuits. This means that the entire air cushion expands.

[0007] Then, when you put your weight on the air cushion, your body contacts many spheres at points. This means that the body is not supported by one plane as in the past, but by a substantial number of points. The weight is evenly distributed, making it comfortable and providing a massage effect on the pressure points of the human body. At the same time, an extremely good air flow path is formed between the points, preventing stuffiness etc. There will be no inconvenience. It also solves various problems with the citations mentioned above. It is possible. In addition, the number of circular sealing parts can be increased by simply reducing the diameter. It can be increased, body pressure distribution and massage effect are further demonstrated, making you feel swaying. The rumbling phenomenon will also be completely eliminated.

【Example】

Examples of the present invention will be described below, but the present invention is not limited only to these examples. It's not.

[0009] The first embodiment is as shown in the plan view of FIG. 1 and the XX sectional view of FIG. However, the main body is made by stacking two or three synthetic resin sheets such as vinyl and sealing the edges. A large number of circular sealing parts 5 having substantially the same shape are arranged over the entire surface of the A communication part 60 is provided between the circular sealing parts 5 to form a ventilation circuit for the system A. A communication section 70 is provided on the row adjacent to the system B to form a ventilation circuit for system A and system B. If they are arranged alternately and the ventilation circuits of the same system are connected through the outermost semicircular sealing part, Both include valves 6 and 7 for introducing and retaining air into each of the two ventilation circuits. Large diameter valves 62 and 72 for venting air are installed on the seat, and air is injected. A cushion 1 was constructed. Note that the reference numeral 50 is a sealing portion on the periphery of the sheet.

0010 The second embodiment will be explained with reference to the plan view of FIG. 3. The cushion 1 of the first embodiment A connector such as a chuck 8 is attached to the side edge of the chuck 8. Therefore, a desired size can be obtained by connecting a plurality of cushions 1, for example. It was configured so that it could be used as a bed, etc. In this case, even if one system is damaged, nothing will happen. The effect is that it can be used without any problems.

[0011] The third embodiment is a mat for preventing bedsores, as shown in the plan view of FIG. The mat is made by joining two cushions 1, 1 of the same shape rotationally symmetrically facing each other. Each cushion has two ventilation circuits, and the valve 6 of one cushion 1 is connected to the Connect the pipe 61, connect the pipe 71 to the valve 7, connect it to the pump 9, and Connect the pipes from the valves 6 and 7 of the other cushion 1 to the valves 62 and 72 of the mat. It is connected on the back side of the joint part.

0012 The pump 9 functions to alternately blow air into the two pipes 61 and 71. The spherical air sacs on the mat's two ventilation circuits alternately expand and contract. Because it is repeated, this effect is similar to eliminating body pressure by changing positions without moving the body. It plays a role of This makes it possible to prevent skin blood flow disorders. In particular, in this embodiment, other Very different from similar mats, the body is pinpointed at the top of the spherical air sac. Supports the body to disperse body pressure, provides acupressure-like massage effect, and also massages the entire groove. Because the volume is large, air circulation is very good, and the surface that comes in contact with the mat does not get stuffy. The inconveniences such as feeling sick are also resolved. In addition, this example is a two-layered Manufacturing is easy and low cost because you only need to emboss each half of the sheet twice. Due to its structure, it can be folded back from any direction, so it can be used as a gadget bed, etc. suitable for

[0013] The fourth embodiment is explained by referring to the cross-sectional view of FIG. 5. 2 and 3 and the partition sheet 4 between them, and seal the periphery, and cover the entire surface of the main body. A large number of circular sealing parts 5 having almost the same shape are arranged over the area, and adjacent circular sealing parts 5 on the same row are A communication part 60 is provided between the sealed parts 5 to form a ventilation circuit for system A, and A communication section 70 is provided on the ventilation row to form a ventilation circuit for system B, and to connect system A and system B. If the ventilation circuits of the same system are connected to each other through the outermost semicircular sealing part, the front and back sides will be connected. 4 ventilation circuits are formed, and air is introduced and maintained in each of the 4 ventilation circuits. The valves 6 and 7 for air removal and the large diameter valves 62 and 72 for venting are attached to the seat. The air-filled cushion 1 was constructed by attaching it to the top. The reference numeral 50 indicates the periphery of the sheet. This is the sealing part. In this case, if any one system is damaged, the complementarity is twice that of the first embodiment. can be obtained, and by connecting a large number of cushions 1, this effect can be fully utilized. That is why it is done. However, in the case of this example, it is not necessary to inflate all the air sacs. Therefore, it can be assumed that they have multiple spares in case some parts are damaged.

[0014] Now, since the present invention is not limited to the above-mentioned embodiments, for example, the synthetic resin of the sheet material This includes rubber, etc., and the location of the communication part is arbitrary, and there is only one ventilation circuit. It may also be configured with only one.
