ABSTRACT:
A supporting framework for shelves including crosspieces which are joined to uprights by locking means which include a locking bolt aligned in the direction of the longitudinal axis of the crosspiece, which bolt includes a head projecting beyond the end of the crosspiece with a contact surface which engages frictionally with a gripping surface on the interior surface of the wall of the upright. The bolt is mounted in a bearing mechanism located within the crosspiece wall so that the bolt can pivot between an unlocked and a locked position, the bolt carrying a collar to which an operating element projecting out through a window in the crosspiece wall is joined. The supporting framework is so designed that when the bolt is in the position the contact surface on the bolt head abuts the gripping surface on the interior surface of the wall of the upright.
