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.

A prefabricated drawer cabinet apparatus of the type having a closed bottom surface, a closed top surface, a back wall located between said top and bottom surfaces and first and second side walls relatively perpendicular to said back wall, with a front surface containing at least one drawer slideably mounted between said side walls for storage of suitable materials, comprising:

(a) a top and a bottom box-like housing;
each having two opposite side walls of equal length and height, and two additional side walls perpendicular to said opposite side walls, each of the same relative length and each of a height relatively equal to the height of said opposite side walls, said top and bottom housings each having a closed bottom surface and an open top surface,
(b) a right and a left side wall member, each of the same dimensions and mirror images of each other, said side walls each having an "L" flange along one back side thereof and a "C" flange along the other front side thereof, said side walls being positioned between said top and bottom housings and coupled to said opposite side walls of said top and bottom housings to form a box-like member, with an open front and open back, each of said side walls having at least one support flange extending therefrom and located at the same distance from one of said top and bottom housings with said supporting flanges facing each other,
(c) a back planar panel covering said back opening,
(d) a drawer support frame assembly having first and second channel members extending between and located on said flanges between said side walls, and third and fourth cross channel members perpendicular to and secured to said first and second members to form a support frame assembly of a "picture frame" configuration,
(e) a drawer of a box-like configuration and having first and second sides;
each of which has a bottom flange portion for sliding on said third and fourth cross channels, said drawer positioned on said support frame for withdrawl of the same from said front end opening of said box-like member.
