Abstract
Abstract Two detachably securable structural members, such as a shelf and end wall of a bookcase, the shelf having securement plates mounted on an end face thereof with an L-shaped slot being formed through each plate and into the associated end face of the shelf. One end of each slot is closed, and the other end thereof is open at an edge of the plate and shelf, the slot being of undercut form at least adjacent to its closed end and being of such dimensions that a securement member which projects from the end wall of the bookcase may be slidably moved through the slot from its open end to its closed end. Each securement member has a head and a shank, the head, when he member is at the closed end of the associated slot, being disposed within the wider part of the undercut portion of the slot with the shank projecting through the part of the slot formed through the plate. This latter part of the slot is at least at the undercut portion of the slot of less width than the head. In passing from the open end to the closed end of the slot the head moves over an inclined portion and on to a portion parallel to the end face of the shelf whereby this face of the shelf and the end wall of the bookcase are urged together during this movement.
