Abstract
An extendable mast of the joint type constructed by freely swingably connecting essentially-rigid members to one another. It includes a plurality of battens extending in the traverse direction of the mast, a plurality of longerons extending in the longitudinal direction of the mast to connect battens adjacent in the longitudinal direction of the mask, and diagonals arranged along the diagonal lines of a rectangle which is formed by the two battens adjacent in the longitudinal direction of the mast and by the two longerons adjacent in the traverse direction thereof. Each of the longerons consists of a pair of beam members freely swingably connected to each other and when these beam members are folded, the mast is also folded compact. The diagonal comprises plural slider members slidable relative to each other and it can be extended to a full length. When these diagonals are extended to their full length, the beam members are locked under overcenter condition.
