Abstract

A drawer slide set includes a two part guide and a two part slide. The guide is made of a first plate which is formed into a guide-connector having a roller rotatably mounted thereon. The guide-connector has a profiled end which extends into a correspondingly shaped channel in a one piece guide rail. Screws or rivets fasten the guide-connector to the guide-rail. The two part slide comprises a one piece slide rail which defines a channel that receives the profiled end of a plate formed into a slide-connector. A roller is rotatably mounted to one end of the slide-connector.

Claims

1. A drawer slide set comprising:

a guide for connection to the interior of a cabinet, said guide comprising a guide-connector (1) formed of a single plate having an inner portion (11) with upper and lower hook profiles, and an outer portion, a roller (5) rotatably mounted to a side of said outer portion of the single plate forming the guide-connector, a guide-rail (2) formed by a single molded piece of material and having upper and lower curved flanges (22), said guide-rail having a channel (21) therein with a shape confirming to the shape of the inner portion of the guide-connector for receiving the inner portion of the guide-connector therein near an outer end of the guide-rail, said guide including means for fixing said guide-connector to said guide-rail;

a slide adapted for connection to the side of a drawer for sliding engagement on said guide to permit the draw to slide into and out of the cabinet, said slide comprising a slide-connector (3) formed of a single plate having an outer end (31) and upper and lower bent edges (32,

     33), said slide-connector having an inner portion and a roller (6) rotatably mounted to a side of said inner portion of said slide-connector, said slide including a slide-rail (4) with an upper arc flange (42) on an upper edge thereof and a V-shaped channel (41) formed under said arc flange near the upper edge of said slide-rail, said slide-rail including an inclined base (43) defining a recess, said outer end with said upper and lower bent edges of said slide-connector conforming in shape to said V-shaped channel and the recess form by said inclined base, said outer end with said upper and lower bent edges of said slide-connector being received within said V-shaped channel and the recess of said inclined base, said slide including means for fixing said slide connector to said slide-rail; and

said upper curved flange (22) being larger than said arc flange (42) so that with said slide slidably engaged to said guide, said arc flange is in sliding contact under said curved flange and, with relative movement between said sliding guide, said rollers (5,

     6) of said guide-connector and said slide-connector roll respectively on said slide-rail (4) and said guide-rail (2).

2. A drawer slide set according to claim 1, wherein said outer end of said slide-connector is inclined downwardly and outwardly from said upper bent edge to said lower bent edge.

3. A drawer slide set according to claim 2, wherein said fixing means of said guide comprise mating holes through said guide-rail and said guide-connector, for receiving fasteners to connect said guide-rail to said guide-connector.

4. A drawer slide set according to claim 3, wherein said fixing means of said slide comprise mating holes in said slide-rail and said slide-connector for receiving fasteners for connecting said slide-rail to said slide-connector.
