Abstract
Abstract The invention is an assembly, kit, or set of component parts for assembling, erecting or constructing geometric figures or shapes. The set of parts may take the form of a toy or it may be a set designed for purposes of research, scientific studies, mathematical displays and illustrations, architectural studies, etc. The parts include connectors (universal nodes); struts, bond links (coupling members); splices; face links (coupling members); and face or perimeter members. Preferably all parts or components are dimensionally coordinated and color coded so that the erection of forms or figures proceeds in accordance with predetermined patterns. Connectors or nodes include a universal node comprising a central member having spokes arranged in a predetermined array extending outwardly from the center along radii of a sphere. By means of the universal node and other parts (face members) there may be constructed a universal atom and various simulated molecular and other structures as well as geometric space-filling figures identified as nodal polyhedra.
