Metal cabinet for assembly by the user from knocked-down condition

Abstract

A rectangular metal cabinet of the panel type intended for sale and transport in a knocked-down condition for assembly with self-tapping screws penetrating the mated edges of the panels. The rear panel has flanges along its lateral edges and the side panels have flanges along their front edges, the flanges being of the box type to impart torsional rigidity at the four upright corners of the cabinet and to receive as well as shield and conceal the tips of the self-tapping screws. The cabinet has one or more rectangular shelves dimensioned to extend to the walls thereof, with the upright flanges being notched out at shelf level by an amount equal to the thickness dimension of the shelf to enable engagement between the edges of the shelf and the walls of the cabinet as well as support for the shelf in the vertical direction. The rear panel consists of left and right-hand sections which are symmetrical and of identical width having box type flanges at their central edges joined in abutting relation. Each of the doors has a flange of box type extending about the periphery to define a central panel. A reinforcing channel having integral wing portions is rigidly adhered to the panel. The wing portions are angled at a shallow angle to define holding spaces of sharply acute cross section containing a charge of adhesive. The structure is preferably fabricated by punching and bending of prefinished stock with avoidance of localized heating by spot welding or the like.
