ABSTRACT:
The invention is embodied in a modular system for making structural frameworks in which crystal-like hubs are used to connect lightweight struts in a variety of configurations. The hubs are comprised of uniform nodes and cylindrical trunnions, several embodiments of which be used in a structural configuration to create irregular shapes. The struts are equipped with end grips which snap into engagement with the trunnions and nodes of the crystal-like hubs. The end grips have C-shaped gripping sections and stems which fit into a hollow tube which forms the body of the strut. The end grips are free to rotate about the axis of the strut, and the end grips can rotate about the axis of the trunnions to which it is attached. Such freedom of rotation allows complete flexibility of design.
