Abstract
A vertical post is rotatably mounted in a corner cabinet and supports a plurality of rotatable shelves which carry the cabinet door. The lower end of the post is rotatably supported by a lower bearing element which rests on a bearing member on the bottom wall of the cabinet. To enable the post and the door to be adjusted vertically, the lower bearing element is a slide supported for up and down movement in the post and having a downwardly inclined ramp on its upper end. A downwardly inclined screw extends perpendicular to the ramp and may be tightened and loosened to shift the slide downwardly and upwardly relative to the post. The head of the screw is sunk within the post to enable the shelves to be slipped onto the lower end of the post during assembly and to enable one of the shelves to pass upwardly by the location of the screw.
