Abstract: A staging lock (22) is movably mounted to an intermediate member (16), and has a follower tab (58) and a lock tab (66). When the intermediate member (16) is fully extended from within the cabinet member (14), the follower tab (58) engages a cam form (106) on the cabinet member (14) and moves the staging lock (22) from a closed position to an open position. When the staging lock (22) is disposed in the closed position, the lock tab (66) engages a staging lock catch (114) on the chassis member (18) to secure the chassis member (18) in a fully retracted position within the intermediate member (16). When the staging lock (22) is moved to the open position, the chassis member (18) may extend from within the intermediate member (16). A rear lock (24) retains the intermediate member (16) in a fully extended position until the chassis member (18) is fully retracted within the intermediate member (16).

Abstract: A drawer slide (12) is provided with a front release lock (32) and disconnect lock (34) moveably mounted a first slide member (14) for engaging opposite sides of a stopper (28) mounted to a second slide member (16). A release linkage (22) is slidably secured to the first slide member (14) for moving the release lock (32) from a lock position to a release position, spaced apart from the stopper (28), to allow the first slide member (14) to retract into the second slide member (16). A disconnect linkage (24) is slidably secured to the first slide member (14) for moving the disconnect lock (34) from a retaining position to a disconnect position, spaced apart from the catch (30), to allow the first slide member (14) to be removed from the second slide member (16). The front release lock (32) and the disconnect lock (34) are slideably secured within a bracket (36) with bias springs (38, 40) urging the release lock (32) into the lock position and the disconnect lock (34) into the retaining position.

Abstract: A mounting bracket (22) is provided for securing to both square-hole racks (12) and round hole racks (16). An inner support pin (24) extends for fitting within round-shaped holes (18) and engaging a side of the round-hole racks (16). An outer support sleeve (26) is slidably moveable over the inner support pin (24) for fitting within square-shaped holes (14) and engaging a side of the square-hole racks (16). A bias spring (40) urges the outer support sleeve (26) to extend over the inner support pin (24). A lock pin assembly (27) has an enlarged diameter portion (30) for fitting within the square holes (14) and a smaller diameter portion (28) for fitting within the round holes (18) to lock the support sleeve (26) and the support in (24) in mounting holes (14 and 18) of respective ones of the square-hole racks (12) and the round-hole racks (16).
