ABSTRACT:
An arrangement for detachably securing together pairs of substantially perpendicular thin-walled, planar, generally flat structural parts (1, 2) which may define wall, top, bottom and/or side members as in the frame of data processing apparatus. A first structural part (1) is provided with calibrated slot openings (3a) for receiving contoured projections (4) on the second structural part (2). The first part (1) also includes at least a passage (8) through which a threaded screw (6) is journaled, and the second part (2) is provided with a cutout 10, opposite the screw passage (8) and aligned with the passage axis (9), configured and dimensioned for engagement with the threads of the screw (6). This arrangement enables detachable securement of the first and second structural parts (1, 2) utilizing a minimum of separate components and a minimum number of assembly steps or operations thus yielding a considerably more cost-effective attachment arrangement than heretofore known.
