Japanese Patent JP2000130688
Kind Code:
A
Abstract:

To provide a three-dimensionally developed structure which can materialize a novel shape such as a hemispherical shape or a spherical surface (closed curve surface), and which can be three-dimensionally expanded and contracted by a large rate.

A three-dimensionally developed structure 1 composed of a plurality of segments which are turnably joined together, can be expanded and contracted in its entire shape by bending the joined parts. A plurality of units having different lengths and each composed of segments arranged in two stages, and combined in a series by one turn in the peripheral direction, are laid in series in the longitudinal direction, and further, rectangular shape segments and triangular segments are alternatively joined together so as to have a specific closed curve line L1 which is not deformed with respect to the longitudinal development.
