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.

[ What is claimed is:] [1.] An assembly comprising:an outer segment fixable to a surrounding frame;a middle segment slidable with respect to the outer segment;an inner segment slidable with respect to the middle segment;an interlock positioned generally between the middle segment and the inner segment, the interlock including at least a first portion movable toward and away from said inner segment, said first portion being movable between a first position in which the inner segment and the middle segment are locked to move together in a first direction and second direction, and a second position in which the inner segment is free to move with respect to the middle segment in said first direction and said second direction, wherein said interlock further comprises a second portion fixed with respect to one of said inner segment and said middle segment, wherein said interlock comprises a single piece, wherein said first portion is cantilevered with respect to said second portion and said interlock is resilient, wherein said first portion defines a camming surface which cooperates with one of said outer segment and said inner segment to move said interlock between one of said first position and said second position and said second position and said first position, wherein said inner segment defines a first edge which defines a first aperture within which said first portion is located when said interlock is in said first position.
