A COMPLIANT DERAILLEUR

摘要

A derailleur (10), or bicycle derailleur, for moving a chain (21) from one location to another while maintaining parallel alignment to a set of gears (19) mounted to a bicycle (12) includes first and second rigid segments (18, 22). The segments are parallel to each other and the first segment is fixed to the cycle, while the second segment is free to traverse from a first to a second position (P1, P2). First linking means (24) is coupled between the first and second segments for linking the first and second rigid segments together, and moves from the first position to the second position. Second linking means (20) is coupled between the first and second segments, and spaced from the first linking means in about a parallel position, for linking the first and second rigid segments together, and for resiliently biasing the derailleur into the first position and for resiliently bending into the second position.
