Assembly for the self-adjustment of a cable casing

Abstract

An assembly for the self-adjustment of a casing of the type having a cable slideably mounted therein to remove excess slack from the casing. The cable extends between a lever of a vehicle temperature control module and a door movably mounted on a forward bulkhead of the vehicle. A first mounting member is attached adjacent the control module lever and is adapted for mounting a tang ring, a release bushing and a retaining insert therein, and for slideably receiving a movable end of the cable casing. The retaining insert retains the tang ring and the release bushing in the first mounting member. A second mounting member is attached adjacent the bulkhead door and immovably mounts the other end of the casing. The tang ring includes a plurality of tangs which are positioned to permit movement of the movable casing end therethrough in a first direction upon a predetermined amount of force being exerted on the casing for removing slack from the casing upon manual adjustment of the lever in a predetermined direction. The tangs maintain the casing end in an adjusted position and restrain movement thereof in a second direction opposite to the first direction. A plurality of lugs formed on the release bushing pass through the tang ring when the bushing is manually moved in the first direction, and engage and force the tangs out of engagement with the movable casing end to permit movement of the casing end in the second direction if desired.
