Abstract
Abstract There is disclosed a prefabricated file cabinet which employs a top and bottom rectangular pan member; each having side walls and a front wall having a depending flange emanating therefrom. The side walls of the module have two L shaped brackets secured thereto; which brackets support a drawer support frame member. The frame member consists of four channels forming a rectangular picture frame with a front and back channel of an L shaped configuration having two side channels with a C shaped configuration secured thereto. A prefabricated drawer consists of side assemblies; each of which has a bottom flange coupled to a C shaped slide flange. The drawer assembly is prefabricated and a front and back panel are secured to the side panels by means of flanges associated with each side panel. A bottom drawer assembly is inserted into bottom flanges also integral with the side panel and functions to secure the front and back panels thereto. The assembled drawer is inserted such that the bottom channels slide within the slide channels of the frame support. Stops are provided on the drawer sides to limit the movement of the drawers once positioned within the cabinet. The cabinet is entirely prefabricated using a plurality of sheet metal panels formed by simple stamping and bending techniques.
