Abstract
A flexible track or roadbed is provided for enabling miniature vehicles, such as toy cars, trains or the like, to be propelled along its length. The track in one embodiment is in the form of an elongated ribbon of flexible, electrically insulating rubber-like material, with serrations in each side thereof, to permit the track to be placed on any planar or non-planar supporting surface, with the track assuming vertical undulations corresponding to any undulations in the supporting surface, and to permit the track to be readily turned into any desired lateral curved, circular or tortuous shape, the track having one or more guide slots extending along the length of the track to guide the vehicles along the track, and a longitudinally extensible and compressible elongated electric element miniature vehicles propelled along the track. In the second embodiment the track is formed of a series of rigid articulated traverse elements intercoupled to one another.
