Abstract:
A flexible joint construction toy comprised of:an axially extending rivet, said rivet including a bearing surface and first and second spaced apart restraining bosses, at least said first boss being located adjacent an end of said rivet and including a chamfered edge;at least two hub assemblies, each hub assembly including a substantially toroid-shaped washer and a connector extending outwardly from the outer circumference of said washer, the thickness of said washer in the axial direction being approximately one-half the thickness of said connector;the diameter of the end of said first boss being less than the diameter of the opening in each of said washers whereby each of said hub assemblies is adapted to be forced over said chamfered edge of said first boss so that said washer fits around said bearing surface between said first and second bosses and wherein said washer is free to rotate about said rivet, the length of said bearing surface between said first and second bosses being substantially equal to the combined thickness of said two washers so that axial movement of said washers is substantially prevented by said first and second bosses.
