A collapsible volume frame, when erected, presents in each of two opposite side elevations a side space frame defined by four points which if joined would form a quadrilateral; and presents further space frames in the four other aspects. The side space frames are braced by at least one frame element disposed transversely and articulated to them in a triangulated manner. Releasable means resist collapse of the volume frame. These side and further space frames are foldable so that the volume frame when collapsed forms a bundle.
