ABSTRACT:
A leveling device for vehicle wheels comprising a first integral planar member for mating with one or more additional integral planar members of substantially the same shape and dimension in releasable relationship. All integral members have four sides and an upper surface divided into a plurality of vertically projecting rows of pins with a row of projections situated up front. The bottom surface of each of the integral planar members include rows of sockets, each of which is conformable in shape and size to receive an individual pin in releasable frictional engagement. Each planar member also includes one partially beveled side with a sloped projection with one or more openings conformable to the shape and dimensions of the individual pins. Two or more integral planar members are adapted to stack one upon the other by mating pins and sockets of respective planar members so that the sloped projections overlap one another and are positioned in parallel relation. The sloped projections of stacked planar members may also be disposed in a laterally offset relation. Both embodiments enable substantial alignment of the inclined planes to facilitate movement of a vehicle wheel up on to the surface of the device and back down.
