なうエアージヤツキに関するものである。[Detailed description of the invention] This invention supplies air pressure to inflate an air bag formed into a mat shape, and uses the expansion force of the air bag to lift or move objects during lifesaving work in accidents and other operations. This relates to air jacking.
この種エアージヤツキは、その使用目的上、エ
アーバツグには可成りの強度を備えることが要求

チールワイヤーを交差させて埋設する方法が採用
されている。 Due to the intended use of this type of air jack, the air bag is required to have a considerable degree of strength, and conventional methods of imparting this strength have involved making the elastic layer (rubber layer) of the air bag body sufficiently thick over its entire surface, or by embedding cross-shaped steel wires in the elastic layer.
しかしながら、前者にあつては、バツグが可成

供給装置も大掛りになつてしまう欠点がある。 However, in the former case, the bag becomes considerably thicker and heavier, which makes it difficult to handle and requires high material costs, while in the latter case, the bag also becomes considerably heavier and more time-consuming to manufacture, which results in high costs.Furthermore, in the latter case, the elastic layer is strongly reinforced with steel wires, so that a considerably high air pressure must be introduced when the bag is inflated, which results in the disadvantage that the air supply device must be large in size.
本考案は上記に着目し、従来の前記諸問題を解

うに構成したものである。 As a result of various research experiments, the inventors of the present invention discovered that when the bag expands, weight is added toward the center of the bag body.Therefore, a reinforcing belt was placed along the perpendicular center line of both surfaces of the bag body. In addition, the belt end is made to protrude an appropriate length from the edge of the air bag body to form a loop-shaped handle piece, and this handle piece allows handling operations such as inserting and pulling out the bag. It is designed so that it can be carried out smoothly.

In the embodiment, they are made of appropriately woven nylon fibers, and both ends of both belts 6 and 7 are connected by sewing or the like. It is formed into an endless belt shape. Both belts 6 and 7 are aligned along the perpendicular center lines of both surfaces of the air bag main body 1, sandwiching the surfaces of both elastic layers 4 and 5 of the air bag main body, and fixed in a cross shape. , 7 are made to protrude from the edge of the bag body 1 by appropriate lengths, and loop-shaped handle pieces 8a, 8b and 9a, 9b are formed by the upper and lower pieces of the protruding parts, and the handle pieces 8a, The upper and lower pieces 8b, 9a, 9b are fastened 10, 11 near the edge of the air bag body 1 by sewing or the like. In the embodiment, when fixing the belts 6, 7 to the bag body 1, the belts 6, 7 are first attached to the rubber backing plates 12, 13, which are formed somewhat wider than the belts 6, 7. are sewn 14 using a sewing machine, and in this state, both backing plates 12 and 13 are heated and vulcanized on both surfaces of the bag body 1 to fix them together, thereby forming the belts 6 and 7.
is fixed to the air bag body 1. In the above case, during actual manufacturing, heating and vulcanization of the air bag body 1 and patch plates 12 and 13 are performed.
The heat vulcanization is carried out at the same time.

る。 The present invention is constructed as described above, and is used, for example, in life-saving work such as in a car accident, etc., by pressurizing air into the air chamber 3 of the air bag body 1 to inflate the bag, and use this expansion force to lift an object. As described above, in the present invention, a reinforcement belt made of a flexible material is fixed along the perpendicular center line of both surfaces of the air bag body, thereby increasing the strength of the air bag. (As a result of experiments, the reinforcement belt increased the strength by about 40%.) Therefore, the jacking up work can be done well, and since the air bag does not become thick as a whole, it is lighter in weight and material costs can be reduced. . In addition, a loop-shaped handle piece is formed at each end of the reinforcing belt, so you can hold the air bag when setting or pulling out the air bag to the desired location, making the work easier. At the same time, this handle piece can also be used as a fastening part for a rope or the like connected to an object.
