Abstract
Two vertically spaced shelves with pie-shaped cut outs are rotatably supported on a fixed post in a corner cabinet. Each shelf is rotatably mounted on the post by an anti-friction bearing assembly comprising a rotatable bearing member attached to the shelf and a fixed bearing member attached to the post. To enable the pie-shaped cut out of the shelf to be located in a predetermined angular home position relative to the cabinet door, a detent mechanism is incorporated in the bearing assembly. The detent mechanism includes a cage carried by the rotatable bearing member and supporting a detent ball which snaps into a detent notch in the fixed bearing member to hold the shelf releasably in its home position.
