  • Patent number: 4036542
    Abstract: A knock-down drawer construction held together by resilient clamps. A pair of front clamps, U-shaped in cross section, are fastened to the rear face of the drawer front by threaded fasteners, such as screws or bolts, and the sides of the drawer are inserted into the clamps. Longitudinal slots along the inside faces of the sides support the drawer bottom, and the drawer bottom is retained in position by the drawer back which is fastened to the sides by corner clamps. The clamps are retained in position by integrally formed tabs which are inserted in transverse grooves on the outer faces of the drawer sides. Clearance recesses along the front edges of the drawer sides are formed adjacent each threaded fastener so that the major portion of the front edges may abut the clamps. The front clamps extend along the full length of the front edge, and notches formed in the clamps adjacent the longitudinal slots allow the bottom to extend forward of the clamps to abut the drawer front.
