Abstract
Abstract A roller mounted box shaped cabinet having a rigid exterior framework made up of corner members having center post and sleeve guides projecting therefrom to receive tubular frame members telescoped thereover. The ends of the telescoped tubular frame members are maintained over the center post and sleeve guides by appropriate fastening means forming the rigid cabinet framework. An arrangement of dowels and detents that are mounted to the vertical edges of cabinet walls are fitted into appropriate holes formed in the upstanding frame members to provide an invisible mounting of the cabinet side and back walls to the frame. The edges of cabinet top and bottom panels rest on flanges that project inwardly from the top and bottom tubular frame members.
