Abstract
A cable adjustment device changes the effective length or tension of a control cable which extends between an actuating mechanism and a device to be operated thereby. In the case of a bicycle, the cable adjustment device is coupled to a bicycle actuating mechanism such as a brake lever or a shifter to control a brake or a derailleur. The actuating mechanism has a base or stationary member and a movable member coupled to the base member for moving the control cable. In the preferred embodiment, the cable adjustment device is coupled to the base member. Specifically, a cable guide portion with an internal threaded bore is integrally formed with the base member. This bore threadedly receives an adjusting member which engages the outer casing of the control cable. A torsion spring is coupled between the adjusting member and the cable guide portion to overridably restrict rotational movement therebetween. Specifically, the adjusting member has one or more longitudinally extending channels which are selectively engaged by a nose portion of the torsion spring to control the rotational movement of the adjusting member.
