ABSTRACT:
A rear support structure for a cabinet is disclosed. The support structure includes provision for automatically adjusting the level of the rear of a cabinet to compensate for a supporting surface which slopes from side to side. The support structure comprises a shaft mounted to the rear, underside of the cabinet and extending transversely of the cabinet. Levelling elements associated with each end of the shaft are rotatable with respect to the axis of the shaft. The levelling elements are formed so that rotation of one of the elements, upon engagement with the supporting surface, will reduce the distance between the underside of the cabinet and the supporting surface and will cause the other element to rotate in a direction to increase the distance between the underside of the cabinet and the supporting surface.
