Two-track drawer slide having function of three-track slide
First Claim
1. A drawer cabinet having first and second, spaced apart, parallel, vertical side walls joined at front edges thereof by a front surface, said drawer cabinet having at least one two-track drawer slide assembly having the function of a three-track drawer slide assembly, said two-track drawer slide assembly comprising:
- (a) first and second horizontal, parallel, oppositely disposed outer tracks axially slidably mounted in support means attached to said first and second side walls, respectively;
(b) said support means comprising at least one longitudinally vertical support member for each of said side walls of said cabinet, each vertical flanges formed along front and rear edges of the support member for mounting said vertical support member to and inside of each of said side walls, at least one U-shaped channel formed as one piece with said support member, said U-shaped channel located on said central portion of each vertical support member, said U-shaped channel comprising first and second legs receiving said outertracks therebetween;
first and second, parallel, inner tracks telescopingly axially moveable within said first and second outer tracks, said inner tracks being moveable between;
(1) a first, closed position, with said inner tracks fully inserted in, and supported by, said outer tracks, and with said outer tracks fully disposed within said drawer cabinet, and (2) a second, withdrawn position, with said inner tracks being substantially fully withdrawn from said outer tracks past said front surface of said drawer cabinet, yet remaining supported by said outer tracks, and with said outer tracks fully disposed within said drawer cabinet;
(c) a frame fixedly attached to said first and second inner tracks, said frame not being fully withdrawn past said front surface of said drawer cabinet when said inner tracks are in said second, withdrawn position; and
(d) co-engaging means attached to said inner and outer tracks to become engaged when said inner tracks are withdrawn to said second, withdrawn position, with further withdrawal of said inner tracks past said front surface of said drawer cabinet causing said outer tracks to move axially partially outwardly of said front surface of said drawer cabinet in response to said co-engaging means becoming engaged when said inner tracks are withdrawn to said second, withdrawn position, to move said inner tracks to a third, withdrawn position, to permit said frame to be fully withdrawn past said front surface of said drawer cabinet.

Abstract
A drawer cabinet having side walls joined at front edges thereof by a front surface, with at least one two-track drawer slide assembly including: outer tracks axially slidably mounted in supports attached to the side walls; inner tracks telescopingly axially moveable within the outer tracks, the inner tracks being moveable between: (1) a first, closed position, with the inner tracks fully inserted in, and supported by, the outer tracks, and with the outer tracks fully disposed within the cabinet, and (2) a second, withdrawn position, with the inner tracks being nearly fully withdrawn from the outer tracks past the front surface, yet remaining supported by the outer tracks, and with the outer tracks fully disposed within the cabinet; and a frame attached to the inner tracks, the frame not being fully withdrawn past the front surface when the inner tracks are in the second, withdrawn position; and co-engaging apparatus attached to the inner and outer tracks to become engaged when the inner tracks are withdrawn to the second position, with further withdrawal of the inner tracks past the front surface causing the outer tracks to move axially partially outwardly of the front surface, to move the inner tracks to a third, withdrawn position, to permit the frame to be fully withdrawn past the front surface.
