The method in which the locking mechanism is provided in the deployed portion has the drawbacks that the weight of the deployed portion becomes large and the dimensional ratio before and after deployment cannot be made large. Both the method of constantly increasing the internal pressure and the method of using the pressure of the motor, the spring, and the liquid have the drawbacks that the power generating portion is heavy and has a large size. Also, the method of developing with gas pressure is
In order to maintain the shape, it is necessary to make the expanded portion an airtight structure, which is a drawback that practical application is difficult.

Reference numeral 4 is a reflecting mirror surface supported by the unfolding portion 1 ', and 5 is the unfolding portion in the folded state (the unfolding portion 1).
And a storage support portion for supporting the expanded portion after the storage and expansion of the reflecting mirror surface 4). In this embodiment, there are eight developing portions 1 ', but by installing a plurality of valves 2 and gas inlet pipes corresponding to the plurality of developing portions 1', a plurality of developing portions 1'can be simultaneously opened. You can choose to deploy it individually.

The bag-shaped structure of the developed portion 1 ′ is a thin film 6 on which a cured portion 7 in which fibers are coated with a resin is superposed, and the resin used is one that is cured by contact with the gas fed into the space 8. Therefore, the hardened portion 7 is hardened after the spread portion 1'is spread, and the spread portion 1'is held in a constant shape. The reinforcing rib 7'provided inside the expanded portion 1'is made of the same material as that of the hardened portion 7.

It is used to maintain the shape of the structure of the gas-injected part, such as the stiffening part 7 and the reinforcing ribs 7'shown. However, if both the thin film 6 and the cured portion 7 are made of a material that allows ultraviolet rays to pass therethrough, it is possible to use a resin that is cured by ultraviolet rays even for the inside of the cured portion 7 and the reinforcing ribs 7 '.

大きくすることができる。As described above, according to the present invention, the bag-shaped structure can be deployed by a simple method of press-fitting a gas. Since the deployable structure deploys under the pressure of gas, only a bag-shaped membrane is required and no special mechanism is required. After the deployment, to cure the outer surface, the inner surface or the outer surface and the cured parts provided inside,
Since the shape is kept strong and the pressure of the internal gas is not necessary, the bag-shaped film does not need to be highly airtight, and can be a thin film and can be made extremely lightweight. In addition, since the hardened part is uncured until it is expanded, the expanded structure can be folded into a small size, and the dimensional ratio before and after the expansion can be greatly increased.
以上のように本発明は簡単な構成で、寸法比が大きく、
強固でかつ軽量な展開構造物を容易に作ることができる
効果がある。As described above, the present invention has a simple structure and a large dimensional ratio,
There is an effect that a strong and lightweight deployable structure can be easily manufactured.
