ABSTRACT:
A slide suspension including an inner channel, a middle channel, and an outer channel, with the outer channel being fixed to a surrounding frame, the inner channel being fixed to a drawer or similar expedient, and the middle channel suspended on bearings therebetween. The double-action extension is sequenced so that the inner and middle channels extend together first until the middle channel reaches its full length of travel, at which point the inner channel may extend further. Likewise, the inner channel retracts first into the middle channel, and then the middle channel retracts into the outer channel. An interlock is provided between the inner and middle channels and alternately locks and frees the inner channel with respect to the middle channel. The interlock is preferably a single durable plastic member which is fixed with respect to the middle channel and includes an actuating block spring-biased into a second position in which the inner channel is free to move with respect to the middle channel.
