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in, and supported by, the outer tracks, and with the outer tracks fully disposed within the cabinet, and (2) a second, withdrawn position, with the inner tracks being nearly fully withdrawn from the outer tracks past the front surface, yet remaining supported by the outer tracks, and with the outer tracks fully disposed within the cabinet; and a frame attached to the inner tracks, the frame not being fully withdrawn past the front surface when the inner tracks are in the second, withdrawn position; and co-engaging apparatus attached to the inner and outer tracks to become engaged when the inner tracks are withdrawn to the second position, with further withdrawal of the inner tracks past the front surface causing the outer tracks to move axially partially outwardly of the front surface, to move the inner tracks to a third, withdrawn position, to permit the frame to be fully withdrawn past the front surface.
