ABSTRACT:
A polygonal element is provided for forming polyhedral structures, particularly for use as an educational constructional toy. The polygonal element has side margins each comprising an inner edge, an outer edge, first and second projections extending outwardly of the outer edge and a recess defined by the first and second projections. The first projection comprises a pair of spaced limbs unconnected at their outer ends. The side face of the recess defined by an inner limb of the first projection is an abutment face. One of the side faces of the recess opposite the abutment face and the outer side face of the outer of said limbs is provided with a projecting hinge pip and the other with a corresponding hinge socket. The arrangement is such that when the polygonal element is hingedly connected edge-to-edge with another such element by inserting the first projection of a side margin of each element in the recess of the other so that the abutment faces thereof abut, the pressure exerted on the outer side faces of the limbs will produce sufficient bowing or the side margins to enable the hinge pip of each side margin to spring into the hinge socket of the other side margin.
