ABSTRACT:
A modular educational erector-toy and erector playground equipment and building system for constructing single-level and multi-level toy and playground structures and buildings of widely variable optional combinations of hollow primary tetrahedron modules and secondary tetrahedron and hexahedron modules and tertiary pentahedron and septahedron modules; the modules being full-size, half-size and quarter-size. The modules are bounded by planar walls, with the outer surfaces on one or more walls of each module matching the whole or an integral fraction of the outer surfaces of one or more walls of every other module. Some or all of the walls of the modules have substantial openings or windows therein so as to form planar boundary flanges or webs defining such tetrahedrons, pentahedrons, hexahedrons and septahedrons. The optionally assembled toy and the playground equipment or building is formed by a juxtaposition of matching faces of the modules in registraton and contact with each other and by securing the so juxtaposed modules to each other either by temporary or releasable fastening means (which may be integral or non-integral with the modules) to permit the toy or the playground equipment to be assembled and to be disassembled wholly or in part and to be restructured from time to time in the same or optionally different multi-module structures.
