ABSTRACT:
An extendible structure of the invention is constructed by connecting the radially projecting legs of the spacer with differing longerons through the joints, and then fastening one joint with adjacent another joint at a diagonally opposed position with a bridle. In the extended state of the structure, the spacers are within a plane which is substantially perpendicular to the direction of extension of the structure and the bridles are extended in the diagonal lines between the adjacent joints to thereby form the longerons in a mast-shaped three-dimensional structure, while, in the collapsed state of the structure, the longerons are collapsed in a loop form and the spacers are laid one upon another inside the loop formed by the longerons to thereby produce a cylindrical form in its outer appearance.
