Bicycle derailleur with rotation resistance
First Claim
Patent Images
1. A bicycle derailleur comprising:
- a base member adapted to be mounted to a bicycle;
a movable member movably coupled to the base member;
a chain guide coupled to the movable member for rotation around a rotational axis;
a resistance applying element that applies resistance to rotational movement of the chain guide;
a resistance control element that moves between at least a first position and a different second position;
wherein the resistance control element comprises a lever that operates the resistance applying element;
wherein the lever is disposed at the derailleur;
wherein the resistance control element is operatively coupled to the resistance applying element so that the resistance applying element applies a first resistance to rotational movement of the chain guide when the resistance control element is disposed in the first position and so that the resistance applying element applies a different second resistance to rotational movement of the chain guide when the resistance control element is disposed in the second position.

Abstract
A bicycle derailleur comprises a base member, a movable member movably coupled to the base member, and a chain guide coupled to the movable member for rotation around a rotational axis. A resistance applying element applies resistance to rotational movement of the chain guide, and a resistance control element moves between at least different first and second positions. The resistance control element is operatively coupled to the resistance applying element so that the resistance applying element applies different first and second resistances to rotational movement of the chain guide when the resistance control element is disposed in the respective first and second positions.
