Abstract:

The object of the invention is to provide a flexible track system having a number of identical track sections interconnectable to form curves, banks and slopes, as well as straight segments, each of the sections having an arcuate surface portion with a periphery of a given diameter and an arcuate edge of the same diameter, the edge being configured for proximate engagement with the periphery of the arcuate surface of an adjacent section. Depending ribs are provided at the periphery for frictionally engaging slots in proximate relation to the edge, the slots being elongate for enabling pivotal movement of one section relative to the next. Upwardly diverging sidewalls are configured for overlapping frictional engagement for assisting in maintaining interconnected sections in fixed relation. The arcuate surface portion is deflectable to enable the formation of sloping segments of roadway. Other track sections are provided with mating interconnections on one end thereof for providing interconnection to other types of track sections.
