ABSTRACT:
An adjustable wheel chock assembly is provided which comprises a pair of reversible wheel chocks slidingly mounted upon a spacer bar assembly. The wheel chocks may be oriented in any one of four positions. In a first position, the chocks are oriented to engage adjacent sides of each of a pair of spaced aligned wheels mounted upon parallel axles. In a second position the chocks are oriented to engage opposite sides of a single wheel. In a third position the chocks are oriented to engage opposite sides of each of a pair of spaced aligned wheels mounted upon parallel axles. In a fourth position the chocks are oriented to engage alternate sides of a pair of spaced aligned wheels mounted upon parallel axles. The chock assembly is of a lightweight but very strong construction, being made from a heavy gauge perforated steel plate. The reversible chocks are of a symmetric design so that one of said chocks may be inverted so as to mate with the other chock, the combination of said chocks in this configuration comprising a rectangular parallelepiped which may be conveniently packaged for shipping or storage.
