Abstract
Abstract A motion transmitting remote control assembly including a core element movably supported in a conduit. A support member (18) adapted to be connected to a support structure and is attached to the conduit (12) and a slider member (28) slideably disposed in a passageway (24) extending longitudinally through the support member (18). The slider member (28) includes a plurality of locking teeth (62) spaced longitudinally along the slider member (28). The support member (18) also includes a closed cavity (38) extending from one side of the conduit (12) which supports an integral locking means (34) and a spring (36). The locking means (34) is adjacent the slider member (28) and includes a plurality of locking teeth (64) extending for a width coextensive to that of the cavity (38) and spring (36). The spring (36) is between the support member (18) and the locking means (34) to urge the locking means (34) into engagement with the slider member (28) for normally preventing longitudinal movement of the conduit (12).

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
216 words
A motion transmitting remote control assembly of the type for transmitting forces along a curved path by a motion transmitting core element, said assembly comprising: a flexible conduit (12) having opposite ends, a flexible motion transmitting core element (16) movably supported by said conduit (12), a support member (18) for supporting said conduit (12), locking means (34) movable transversely to said conduit (12) into and out of engagement with said conduit (12) for controlling the longitudinal movement thereof relative to said support member (18), biasing means (36) reacting between said support member (18) and said locking means (34) for urging said locking means (34) into engagement with said conduit (12) while allowing said locking means (34) to be moved out of engagement with said conduit (12) in response to a predetermined force, said locking means (34) characterized by said support member (18) defining a closed cavity (38) on a first side of said conduit (12) and said locking means (34) being an integral member having a locking portion (64) engaging said first side of said conduit (12), said biasing means (36) being disposed in said closed cavity (38) to react between said cavity (38) of said support member (18) and said locking means (34) to urge said locking portion (34) into engagement with said conduit (12).
Claim 2
Dependent Claim
216 words
A motion transmitting remote control assembly of the type for transmitting forces along a curved path by a motion transmitting core element, said assembly comprising: a flexible conduit (12) having opposite ends, a flexible motion transmitting core element (16) movably supported by said conduit (12), a support member (18) for supporting said conduit (12), locking means (34) movable transversely to said conduit (12) into and out of engagement with said conduit (12) for controlling the longitudinal movement thereof relative to said support member (18), biasing means (36) reacting between said support member (18) and said locking means (34) for urging said locking means (34) into engagement with said conduit (12) while allowing said locking means (34) to be moved out of engagement with said conduit (12) in response to a predetermined force, said locking means (34) characterized by said support member (18) defining a closed cavity (38) on a first side of said conduit (12) and said locking means (34) being an integral member having a locking portion (64) engaging said first side of said conduit (12), said biasing means (36) being disposed in said closed cavity (38) to react between said cavity (38) of said support member (18) and said locking means (34) to urge said locking portion (34) into engagement with said conduit (12).
Claim 3
Dependent Claim
26 words
An assembly as set forth in claim 1 wherein said locking portion (34) extends for a length coextensive to the width of said biasing means (36).
Claim 4
Dependent Claim
96 words
An assembly as set forth in claim 2 wherein said locking means (34) includes an aperture (24) surrounding said conduit (12) for allowing longitudinal movement of conduit (12) through said locking means (34), said locking means (34) including an integral button (50) disposed on said second and opposite side of said conduit (12) from said biasing means (36) to act against said biasing means (36) when manually depressed to move said locking means (34) out of engagement with said conduit (12) to allow said conduit (12) to move longitudinally in either direction through said aperture (24).
Claim 5
Dependent Claim
54 words
An assembly as set forth in claim 3 wherein said cavity (38) defined by said support member (18) includes a temperature responsive means (42) extending upwardly toward said conduit (12) from the bottom of said closed cavity (38), said integral locking means (34) including a skirt (40) disposed about said temperature responsive means (42).
