摘要

The frame (3) has rigid segments (1) joined with each other by inflatable pouches (2), where inflation (4) of the pouch produces erection of the frame and deflation of the pouch permits the folding of the frame. The inflation of the pouch is produced using a distinct pipe of the frame. Each pouch has a valve that connects a cavity to the pipe. The segments are joined by elastics that are placed near the pouches.
