Abstract:
1. A 3-dimensional polyhedron frame structure comprising: a plurality of hubs having a plurality of sockets that are spaced apart on the exterior of the hub, each said socket having a threaded internal wall; a plurality of rigid rods having a threaded bolt mounted on at least one end by a retraction mechanism that permits the bolt to be retracted into the rod as it is being inserted into a said socket of a said hub and to project from the rod as it is being screwed into said socket to form the frame structure, said bolt having a profiled outer diameter only over a portion thereof located entirely within said rod; and a turning knob rotatable with respect to said rod and having an inner section only located entirely within the rod and having a profiled channel which matches and engages the profiled outer diameter of said bolt, said turning knob further having an outer section external of the rod that projects radially beyond the inner section and is adapted to be manually grasped and rotated so as to rotate said bolt and cause it to be screwed into said socket.
