Abstract
A shifting apparatus for a bicycle includes a takeup element for winding a control cable, a shift lever for engaging and rotating the takeup element, a power takeoff (PTO) mechanism operable with rotation of the takeup element, and a shifter case for rotatably supping the takeup element. The shifter case includes a mounting portion for connecting the shifter case to a handlebar of the bicycle, a coupling section, and a speed indicator mounted on the coupling section. The speed indicator has a movable member operatively connected to the PTO mechanism for indicating a selected speed.
Claims10
A shifting apparatus comprising
- a takeup element;
- a shift lever for engaging and rotating said takeup element;
- power takeoff means operable with rotation of said takeup element;
- a speed indicator including:
- a speed indicator case;
- a support;
- and
- indicating means disposed between said support and said indicator case and supported to said support to rotate about a first axis, said indicating means being connected to said power takeoff means for moving relative to said support in response to a rotation of said takeup element;
- a shifter case for rotatably supporting said takeup element, said shifter case having a coupling section for externally mounting said speed indicator thereon;
- a fastener for fastening said indicator case to said shifter case;
- wherein said speed indicator includes fixing means for fixing said support to said indicator case so that said support remains fixed to said indicator case when said speed indicator is uncoupled from said shifter case;
- wherein said takeup element rotates about a second axis;
- and
- wherein said first and second axes are parallel to each other.
