ABSTRACT:
A frame structure has a structural unit containing six elongated posts, each post having first and second ends, the structural unit capable of having at least an unfolded state where the six posts are substantially contained in one plane and a folded state where the six posts extend substantially parallel to each other. The frame structure has post-midpoint joints formed in each of the posts for supporting the posts of the structural unit foldably at approximate midpoints of the posts; a central joint for supporting the posts of the structural unit at the first ends of each of the posts rotatably in a plane perpendicular to the plane of the unfolded state. The six posts of the structural unit are positioned in the unfolded state such that the posts extend radially from the central joint within substantially one plane, so that a line connecting the second ends of the six posts of the structural unit forms substantially an equilateral hexagon. In addition, the six posts of the structural unit are bound at the first end by way of the central joint in the folded state, and being foldable such that the six posts extend parallel to each other by way of the central joint. The structure does not require a special accessory technique or facility to construct the structure even when a space structure to be constructed becomes larger.
