2. Description of the Related Art In a conventional air bed for a Japanese-style room, for example, when it is not used, it is folded and stored in a closet, and when it is used, the folded one is flattened. In such a case, as shown in FIG. 4 at the folded portion, a metal or synthetic resin material is used between the front and back laminated sheets a in which a knitted material such as nylon is laminated on the inner surface of an airtight sheet material such as vinyl chloride or urethane. A flexible hose in which the laminated sheet a is heat-welded or high-frequency welded with the coil winding material b sandwiched therebetween is considered.

However, in the conventional structure, the laminate sheet a may be damaged if the processing is complicated or the end portion of the coil winding material b is not properly processed. There have been problems such as air leakage and difficulty in processing the ends of such hoses for connection. And as a hose for avoiding such a problem, there are flexible silicone and urethane hoses, and further flexible hoses formed by coiling them, and in such a hose, for example, folding is possible. For air beds for Japanese-style rooms, the hose can be crushed relatively easily to prevent ventilation, and in the case of bending for a long period of time, the inability to breathe cannot be recovered.Therefore, a large space is needed to loosen the bending. It was necessary and there was a problem that it was not suitable for folding the mat.

In this way, the hose is made of a flexible material such as rubber and has the vent hole 1 formed over its entire length, and the hose body 2 is formed in a flat oval shape in its cross-sectional shape. In addition, since the vent hole 1 is formed in a circular cross section, the hose body 2 has a flat oval shape in which the cross section is flat against a pressing force due to bending or the like. It avoids the hose body 2 from being crushed and bent so that all of it buckles, ensuring the ventilation hole 1 even in the bent state, and increasing the restoring force compared to a hose with a circular cross section even when bent for a long time. However, the structure is simplified as compared with the case where the coiled body is interposed between the laminated sheets and welded, and the connection for the hose can be easily completed. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the accompanying drawings. As shown in FIG. 2, the air bed A for a Japanese-style room has a plurality of air mats 3 foldably connected at folds 4. Each air mat body 3 has a cushion material 6 made of a soft urethane foam laid on the upper and lower surfaces of a space surrounded by a frame 5 around a slightly hard urethane foam body. An air pump (not shown) is arranged inside the air mat body 3, and the air tube 7 is connected to the air pump, and the air tube 7 is expanded by driving the air pump. By doing so, an appropriate cushion can be obtained. Further, a solenoid valve (not shown) is built in the air pump, and the solenoid valve and the air pump are operated by operating the solenoid 8 which is wired by a cord or operated wirelessly. By driving, the pressure in each air mat body 3 can be set to a desired pressure. Each air mat body 3 is covered with a quilting 9, and a fold 4 is formed by this quilting 9 so that each air mat body 3 can be folded at the fold 4.

As described above, since the hose body 2 is formed in a flat oval shape in its cross-sectional shape, and the ventilation hole 1 is formed in a circular cross-section, the hose body 2 against pressing force due to bending or the like. 2 is a substantially oval shape with a flat cross-section, and compared to a hose with a circular cross-section, the hose body 2
Avoids being crushed and folded so that all of them buckle. That is, it is possible to avoid crushing the ventilation hole 1 even in the folded state, and to allow ventilation even in the folded state. And even if it is bent for a long period of time, the restoring force is higher than that of a hose with a circular cross section, and it can be restored reliably. In addition, the structure is simplified and the hose connection can be easily performed as compared with the case where the coiled body is interposed between the laminate sheets and welded. A flexible material such as silicone rubber is used for the hose body 2.

As described above, the present invention is a hose which is formed of a flexible material such as rubber and has ventilation holes formed over its entire length, and the hose body has a flat cross-sectional shape. Since the hose is formed in an oval shape and the ventilation hole is formed in a circular cross section, the hose body is a flat oval shape with a flat cross section against pressing force due to bending, etc. It is possible to avoid that the hose body is crushed and buckled so that all of the hose body buckles, and the ventilation hole is secured even in the bent state,
Moreover, even if it is bent for a long period of time, the restoring force can be increased compared to a hose with a circular cross section, yet the structure is simplified compared to the one in which a coiled body is interposed between the laminated sheets and welded. There is an advantage that it can be done and the hose connection can be done easily.
