Abstract: A toy construction kit is provided which includes, as basic building elements, a plurality of tubular elements having transverse throughbores routinely spaced along their length and routinely spaced about their periphery at relative displacements of 30, 45, 60 and 90 degrees. Rod-like elements are also provided for insertion through the transverse bores and may be secured therethrough by bolts screwed into threaded recesses in the ends of the rods. Deformable circular planar connectors are provided to which the rods may be joined through the use of the bolts. A connector has a plurality of flanges or ears about its periphery each of which has a circular opening for permissive joinder of the rods thereto. The rods may eminate from the connector at various angles to thus enable the construction of various geometric forms.

Abstract: A toy construction kit is provided which includes, as basic building elements, a plurality of tubular elements having transverse throughbores routinely spaced along their length and routinely spaced about their periphery at relative displacements of 30, 45, 60 and 90 degrees. Rod-like elements are also provided for insertion though the transverse bores and may be secured therethrough by bolts screwed into threaded recesses in the ends of the rods. Deformable rectilinear planar connectors are provided to which the rods may be joined through the use of the bolts. The connector has a circular opening at each end and at its center for permissive joinder of the rods thereto. The rods may eminate from the connector at various angles to thus enable the construction of various geometric forms. Tubular elements are also provided for insertion into the ends of the basic tubular elements to thus join two of those elements into an unitary member; rods are bolted through the assembly to secure the joint.
