Fluid inflated envelope for multiple use

摘要

A supple envelope (1) closed and folded can return automatically to its original form in a deforming cycle when it is filled with a fluid and return to a folded form when the fluid is exhausted via a valve (4). It consists of a network of rigid supports (2) and a network of elastic pieces (3) joining the opposite walls of the envelope (1) set out alternately throughout the envelope (1).
