Abstract
A retractable wheel assembly for moving an object having a vertical surface for attachment of the wheel assembly, comprising a plurality of arms, each arm having a wheel at one end, a plurality of pivot assemblies for receiving the arms such that when the pivot assemblies are attached to the object, the arms pivot in a vertical plane about the pivot assembly, mounting means for attaching the pivot assemblies to the object, and means for locking the wheel assembly in a retracted position wherein the weight of the wheel assembly maintains the wheel assembly in the retracted position, and for locking the wheel assembly in an extended position wherein the weight of the object maintains the wheel assembly in the extended position.
