Abstract

Abstract A flat rectangular brief case of rigid frame construction having a rectangular recess in one of its side walls, and hingedly supported in said recess a table plate for movement from a submerged position wherein its outer surface is substantially flush with the outer surface of the recessed side wall to a number of raised positions wherein it projects from the recess and its outer surface slopes relative to the outer surface of the recessed wall. Interposed between the underside of the table plate and the bottom surface of the recess are struts for supporting the table plate in a number of raised positions. These struts may be folded relative to the table plate or the bottom surface of the recess so that they will not obstruct return of the table plate to its submerged position within the recess.
