INFLATABLE STRUCTURE DEVELOPING METHOD, FOLDED STRUCTURE DEVELOPING METHOD AND FOLDABLE STRUCTURE

Title:

INFLATABLE STRUCTURE DEVELOPING METHOD, FOLDED STRUCTURE DEVELOPING METHOD AND FOLDABLE STRUCTURE

Document Type and Number:

Japanese Patent JP2003237698

Kind Code:

A

Abstract:

To provide a developing method for inflatable structure foldable in a compact form and predictable in the expanded and developed shape, a method of folding and developing a compactly foldable and expansible structure, and the foldable and developable structure.

A cylindrical membrane member is formed so that the lines intersecting a plurality of faces orthogonal to a cylinder axis respectively become trough lines, and folded beforehand so that each trough line forms a regular N-angular form (N is an integer of 3 or more) and that the regular N-angular forms formed by axially adjacent trough lines are shifted by (180÷N)° around the cylinder axis. A filler is filled inside the folded membrane member to form the membrane member in cylindrical shape.
