Abstract
A leveling leg for an appliance is provided, including a main shaft and a foot coupled to the main shaft. A recess extends at least partially into the foot and includes an opening through a bottom surface of the foot. A ball is adapted to be received within the recess. The opening substantially surrounds at least a portion of the ball and is configured to inhibit removal of the ball from the recess. In one example, the ball is adapted to be received within the recess by a snap-fit engagement with the at least one arm. In another example, a plurality of arms are at least partially disposed within the recess and cooperate at one end thereof to engage the ball at an area below a great circle of the ball to inhibit removal of the ball from the recess.
