Abstract:

Leveling arms for a low profile room air conditioner which are pivotally mounted to a side of an air conditioner housing at an inner end and have an arcuate slotted opening adjacent an outer end. A threaded fastener or clamping bolt is threaded into the air conditioner housing and extends through the arcuate opening. The threaded fastener is loosened to allow the position of the associated arm to be adjusted. The arms have an inner surface providing a series of radial teeth which mesh with like teeth on the outer surface of the housing when the threaded fastener is tightened, thereby retaining the arms in the desired position.
