  • Geometrical constructions
    Patent number: 4121831
    Abstract: A construction in the shape of an octahedron assembles from a plurality of three dimensional U-shaped or V-shaped constructional elements or "pieces." Six identical U-shaped or V-shaped pieces form a single octahedron. Two V-shaped pieces may also form a smaller octahedron. The U-shaped and V-shaped pieces, each having trapezoidal surfaces, can also be used to assemble a variety of non-octahedral constructions. Preferably, the triangular faces of six-piece octahedral constructions are each composed of three trapezoidal surfaces.
