ABSTRACT:
A toy skateboard is provided with steerable truck assemblies having a minimum of parts. Two longitudinally spaced pivots on the underside of the platform hold the trucks on the platform. A leaf spring with three prongs is placed between each truck and the platform. One or more of the prongs are bent away from the plane of the body of the spring with the two outer prongs always located in the same direction. The diameter of the pivots is less than the diameter of the holes through the trucks allowing the trucks to be tilted in any direction about the pivots. Limit walls molded on the undersurface of the platform limit the rotation of the trucks about the pivots. When the platform is tilted, the springs push the trucks out of the straight forward position into the direction of the tilt thereby mimicking the action of a full sized skateboard.
