ABSTRACT:
An endless track concept particularly adapted for a tracked vehicle toy having no track tensioning means and wherein the track is characterized by its simple and economical construction, as required for a toy. This endless track includes a plurality of simply interconnected links, with each link being made solely of a length of wire bent into a generally U-shape configuration. Each link includes a transverse portion and opposite end portions, the transverse portion having a sinusoidal shape defining a wheel-engaging concave central portion, a pair of convex portions at opposite sides respectively of the concave central portion, first legs interconnecting said concave portion to the respective convex portions and serving as wheel guides, second legs outwardly spaced from the first legs and forming extensions of said convex portions, short pivot portions projecting endwise away from the outer ends of said second legs; respectively transversely of the track at substantially the level of said concave central portion, the end portions project from the intermediate portion generally longitudinally of the track and have each a hook engaging the corresponding short pivot portion of a next link. The first legs are sufficiently long to prevent the track from coming out of engagement with the wheel of the vehicle toy, even if there is no track tensioning means on the toy.
