A self-leveling leg assembly for use as the rear legs of a household appliance includes a pair of legs at each rear corner rigidly interconnected by a bar. Each leg carries a projecting pin which fits within a slot and a bracket at each corner, with the slots in both brackets sloping upwardly and outwardly toward the outer wall of the appliance. One of the brackets includes a horizontal slot connected to the top portion of the diagonal slot and positioned so that when the adjacent leg pin is moved from the diagonal slot into the horizontal slot and the other leg pin is at the bottom of its slot, movement of the other leg pin toward the top of its slot causes the one leg pin to move to the inner end of the horizontal slot. A spring-biased locking pin is positioned in the horizontal slot so that when the appliance is lifted off a shipping pallet with both legs in the retracted position, the other leg can fall to the bottom of its slot as the spring-biased locking pin pushes the one leg pin toward the end of the horizontal slot and allows it to drop into the diagonal slot. The locking pin remains in this position to prevent reentry of the pin from the diagonal slot portion into the horizontal slot portion, so that the legs remain in the extended position. |
