Abstract: An objective of the present invention is to provide a deployable structure which enables an element even with high rigidity to be folded. A deployable structure (1A) includes a pair of belt-shaped elements (3A, 3A) and a connecting element (4A), wherein the connecting element (4A) connects the pair of belt-shaped elements (3A, 3A) so as to be freely deformable between a folded state and a deployed state, with corners (307) of the pair of belt-shaped elements (3A, 3A) being in contact with each other on their front faces (301) on one side in a thickness direction of the pair of belt-shaped elements (3A, 3A), wherein the pair of belt-shaped elements (3A, 3A) extends in parallel to a predetermined plane xy in the folded state and perpendicular to the predetermined plane xy in the deployed state. Ends of the front faces (301) of the belt-shaped elements (3A, 3A) are connected to the connecting element (4B) via first bent portions (5) which are bendable along the ends.

Abstract: A deployable structure comprising a side wall having a plurality of segments which make the side wall a tube-like shape as a whole. Four adjacent segments are connected with one another at one point to make one module. The folding patterns of the segments along the connecting creases have two purposes, one of which is a closing pattern to reduce an inner angle between connected segments adjacent in a circumferential direction of the side wall, accompanied with a folding in a direction of a central axis, the other of which is an opening pattern to enlarge the inner angle between connected segments adjacent in the circumferential direction of the side wall, accompanied with a folding in the direction of the central axis. As a result the side wall can be deployed and packaged in both directions of the central axis and the radius of the side wall by folding the segments along the connecting creases thereof in the closing and opening patterns.
