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.

A toy skateboard comprising: a platform having an undersurface; two truck assemblies, each having a mounting aperture; two longitudinally spaced mounting means for retaining said two truck assemblies on said platform adjacent said undersurface, one of said mounting means holding one of said truck assemblies and the other of said mounting means holding the other of said truck assemblies, each mounting means having: a pivot projecting from said undersurface; said pivot passing through said mounting aperture of said truck assembly radially retaining said truck assembly on said pivot; and means for retaining said truck assembly axially on said pivot; means for allowing each of said truck assemblies to be tilted in relation to its pivot; a clockwise limit wall on said undersurface for each of said truck assemblies against which said truck assembly abuts when rotated in a clockwise direction about said pivot; a counterclockwise limit wall on said undersurface for each of said truck assemblies against which said truck assembly abuts when rotated in a counterclockwise direction about said pivot; and means for biasing each of said truck assemblies away from said undersurface including a leaf spring positioned between said truck assembly and said undersurface, said leaf spring including: a body portion having a body plane; three prongs projecting from said body portion substantially parallel to each other, each prong having a tip; and said three prongs spaced when not under load in at least one of said following arrays: said tip of the central of said three prongs spaced from said body plane on a first side of said body plane and said tips of the outer two prongs spaced from said body plane on a second side of said body plane opposite said first side; said tip of said central of said three prongs positioned in said body plane and said tips of said outer two prongs spaced from said body plane on the same side of said body plane; and said tip of said central prong spaced from said body plane and said tips of said outer two prongs positioned in said body plane.
