ABSTRACT:
A motion transmitting remote control assembly (10) comprises a protective tubular conduit (12) and a flexible motion transmitting core element (14) slidably disposed in the conduit (12) for conveying longitudinal forces. A length adjuster (18) adjusts the longitudinal length of the core element (14). The length adjuster (18) includes a housing (20) having a plurality of transverse teeth (22), and a slider (26) which is longitudinally moveable within a track (24) of the housing (20) between maximum and minimum length adjusted positions. A toothed interlock (36) is transversely movable relative to the slider (26) between a shipping condition in which its teeth (44) are disengaged from the teeth (22) of the housing (20) and an engaged condition in which its teeth (44) engage the teeth (22) of the housing (20). A cantilever tang (48) within the interlock (36) is effectively isolated from the longitudinal forces of the core element (14) for automatically restraining the interlock (36) in the locked condition and selectively releasing the interlock (36) to return to the shipping condition for service or readjustment. The cantilever tang (48) has a cam foot (50) which seats in a stop groove (54) of the slider (26) when the interlock (36) is in the shipping condition and seats behind a rear edge (56) of the slider (26) when the interlock (36) is in the engaged condition. The blade of a screw driver (60) or the like can be used to pry the cantilever tang (48) upwardly so that its cam foot (50) unseats from behind the rear edge (56), thereby permitting service and readjustment without damaging the assembly (10) so that it can be reused.
