ABSTRACT:
A lifting and stabilizing system is mounted on a household appliance and includes a lifting system to lift that appliance above a supporting surface, such as a floor so that access to that supporting surface beneath the appliance is provided. The stabilizing system includes a plurality of weighted door-like elements mounted on the appliance to slide from one position to a second position to lower the center of gravity of the weighted appliance. In one embodiment, the center of gravity of the weighted appliance is lowered beneath the supporting system whereby any forces tending to tip the elevated appliance are combined with the weight of the lifted appliance to form a force moment about the lifting elements that is directed to return the appliance to the proper, untipped position.
