Abstract
A display device for use on a multi-speed (multi-gear) bicycle, which indicates the currently selected bicycle gear. The device interfaces directly with a gear changing cable. In one embodiment, a toothed rack is attached to a section of cable running along the bicycle frame. A pinion, attached to a cylindrical indicator meshes with the rack. In an embodiment for remote mounting, a slave cable is attached to the gear changing cable to transmit the motion of the gear changing cable to the remote location.
Claims20
A gear display accessory device for attachment to a multi-gear bicycle, said bicycle having cable-operated gear shifting means with a gear shift cable extending between a shift lever and a gear shifting mechanism, comprising:
- means for interfacing with the gear shift cable comprising clamping means said means for interfacing for clamping to an exposed portion of the gear shift cable between the shift lever and the gear shifting mechanism;
- display means for indicating a currently selected gear;
- means for coupling the display means to the cable interfacing means;
- and
- a housing.
A gear display device for a multi-gear bicycle, said bicycle having a frame and having first and second cable-operated gear shifting means with first and second gear shift cables routed along the frame, comprising:
- a housing including a clamp for mounting on the bicycle and a cover with at least one window;
- means for interfacing with the first and second gear shift cables including:
- first and second slave cables each having first and second ends, the first end of each cable being clamped to the respective first and second gear shift cables;
- first and second slave cable casings enclosing segments of the respective slave cables and having one end coupled to the bicycle frame and another end coupled to the housing;
- first and second toothed racks coupled to the second ends of the respective slave cables;
- display means for indicating respective gears currently selected by said first and second gear shifting means, including first and second indicator members, which indicator members include indicia corresponding to the respective gears of the first and second gear changing means;
- and
- means for coupling the display means to the cable interfacing means including first and second pinion gears coupled to the respective indicator members and positioned in mesh with the first and second racks respectively and coupled to the housing for axial rotation, such that longitudinal motion of the first and second gear shift cables rotates the respective pinion.
A gear display device for a multi-gear bicycle, said bicycle having cable-operated gear shifting means with a gear shift cable, comprising:
- a housing;
- means for interfacing with the gear shift cable, including a toothed rack attached to the gear shift cable and oriented substantially parallel thereto;
- display means for indicating a currently selected gear, including a pinion gear positioned in mesh with the rack and coupled to the housing for axial rotation, such that longitudinal motion of the gear shifting cable rotates the pinion;
- and
- means for coupling the display means to the cable interfacing means, including an indicator member with indicia disposed thereon corresponding to respective gears wherein the indicator member is substantially cylindrical and is coaxially attached to the pinion.
A gear display device for a multi-gear bicycle, said bicycle having first and second cable-operated gear shifting means with respective first and second gear shift cables, comprising:
- a housing;
- first means for interfacing with the first gear shift cable;
- first display means for indicating a gear currently selected by the first gear shifting means;
- means for coupling the first display means to the first cable interfacing means;
- second means for interfacing with the second gear shift cable;
- second display means for indicating a gear currently selected by the second gear shifting means;
- and
- means for coupling the second display means to the second interfacing means.
