Patent ID: 6840133

Claim:
An override mechanism for a cable tensioning mechanism in which a cable is tensioned by a motor against the reaction thrust of a flexible outer conduit for the cable, the release mechanism comprising: a hollow abutment member fastened to one end of the flexible outer conduit of the cable, the cable passing through the hollow center of the abutment member for connection to a motor-actuated tensioning drive nut; a housing in which the abutment member can slide axially; a stop member associated with the housing for engaging with a shoulder on the abutment member for arresting sliding movement of the abutment member in the housing and establishing a reaction surface against which the abutment member and the outer conduit bear when the cable is tensioned; and means for selectively moving the stop member so that the stop member is out of engagement with the shoulder of the abutment member to permit axial movement of the abutment member in the housing when it is desired to release the tension in the cable.
