ABSTRACT:
A self-locking support mechanism for leveling an appliance relative to the floor that includes a support member secured to the appliance and having at least one end wall and one side wall with the side wall having a slot therethrough. There is also provided a rotatable cam member having a pivot point, a cam surface to contact the floor for height adjustment, and a radius surface relative to the pivot point. The cam member rotates by a pin through the pivot point and the slot in the support member and the pin is slidably movable within the slot. The slot and support end wall are spaced from each other and converge toward each other in a direction away from the floor. Upon rotating the cam member the pin is moved within the slot away from the floor and the cam member radius surface abuts the support end wall to lock the cam member.
