SPACE-EXPANSION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a space-expansion structure capable of forming a two- dimensionally expanded plane without impairing the profile irregularity of films by arranging inflatable tubes in lattice or radially. SOLUTION: This space-expansion structure comprises plural easily- deformable films 4, inflatable tubes 5 arranged in lattice for connecting the two-dimensionally arranged films 4, and a cylinder mounted on one end of the inflatable tube 5 or a cylinder 6 comprising a flow rate control mechanism, and the structure is folded in a state the inflatable tubes 5 as folds are in parallel with each other, and then totally cylindrically rounded to be accommodated, so that it can be two-dimensionally expanded when a gas is charged from the cylinder 6.
