1. A system of interconnectable building modules, each module comprising:
- a triangular wall element having a base leg and two standing legs, the legs each defining a longitudinal axis, and the wall element defining a plane, the base leg and the standing legs being elongated members joinable at their ends to one another in an isosceles triangle having an angle of about fifty-five degrees between the longitudinal axis of said base leg and the longitudinal axes of each said standing leg and having an angle of about seventy degrees between the longitudinal axes of said two standing legs, the standing legs each having a connection hole oriented perpendicular to the respective longitudinal axes of the standing legs and oriented at 60 degrees to a plane defined by said isosceles triangle, and the base leg having a connection hole oriented perpendicular to the longitudinal axis of said base leg and oriented at forty-five degrees to said plane of said triangle, four said triangular wall elements forming a substantially tetrahedral building module when connected using coextensive connection holes, the four triangular wall elements being connected in a tetrahedron, said four wall elements defining a base plane, two sloping planes and a fourth plane perpendicular to said base plane, said elements, attached to one another along coextensive base legs, said base legs and said standing legs each further having at least one facewise-connecting hole oriented perpendicular to the respective longitudinal axis of said legs and perpendicular to the plane of said triangular element, whereby the triangular element is connectable in register directly to an additional triangular element placed thereupon, and whereby the tetrahedral building module can be attached to other tetrahedral building modules to form structures.

Abstract
A system of interconnectable modular frame components for construction toys, playground climbing equipment and the like is based upon tubular triangular leg elements joined at about fifty-four degrees, forty-four minutes and seventy degrees, thirty-two minutes, being thereby modularly stackable at specific useful orientations. Complete triangular wall elements are joined with other complete triangular wall elements, forming tetrahedral modules which are then combined with other such modules by transverse attachment of the tubular legs of each said module, the tubular legs being coextensive structural elements in structures built from attached modules.
