Abstract
A bicycle derailleur comprising a chain guide movable between intermediate positions. An actuation arm associated with the derailleur has a cable seat formed it. A cable-clamping washer includes with a cable-bending appendage that is insertable in the seat of the actuation arm. The actuation arm cooperates with the cable-bending appendage to lock an actuation cable in the desired position.
Claims20
A bicycle derailleur comprising:
- a chain guide configured to interact with a transmission chain of a bicycle and moves among a plurality of intermediate positions between an inner position and an outer position;
- a fixed body configured for being fixedly associated with a part of a frame of the bicycle;
- an outer connection element rotatably connected to the fixed body about a first articulation axis (A) and rotatably connected to the chain guide about a second articulation axis (B) that is parallel to the first articulation axis (A);
- an inner connection element rotatably connected to the fixed body about a third articulation axis (C) and to the chain guide about a fourth articulation axis (D);
- an actuation arm hinged to the fixed body about the first articulation axis (A);
- and,
- a cable-clamping washer that includes a cable-bending appendage that mates with a seat formed in the actuation arm;
- said seat extending along a first direction (F) and being provided with a first insertion opening and a second insertion opening that are opposite one another and selectively engageable by said cable-bending appendage of the cable-clamping washer;
- wherein said cable-clamping washer has a pair of cable-guiding grooves that are on an inner surface and substantially parallel to one another and spaced apart, and
- wherein said cable-bending appendage extends in a direction substantially perpendicular to said inner surface of said cable-clamping washer.
