Abstract
Abstract A fifth leg for a merchandising machine cabinet having a door carrying a secondary merchandising unit and having a principal merchandising unit mounted in the cabinet so as to permit it to be swung out of the cabinet for loading, in which a leg pivoted on the door at a location remote from the door hinge moves from a retracted position to an extended position in response to movement of the door from said partially open position to said fully closed position so as to balance the machine whenever the door is between its partially open position and its fully open position.
