Abstract
Abstract A multishelf cabinet, open at the front, is made up of a back and two end members joined by block hinges at the upright corners for folding of the ends inwardly against the back. The back is split vertically at the center and the two pieces are hinged together for folding backwardly upon each other. When open a plurality of shelves fit within the cabinet space provided and have tenons extending through mortises in the back and the ends. The ends of the tenons have vertical holes into which wooden clothespins fit to secure the assembly together. A canvas or wooden front may be provided with suitable fastenings to protect the storage items placed on the shelves.
