Abstract:
A bicycle gear shifter comprises a shift positioning ratchet provided with a number of positioning teeth, release teeth and drive teeth, a drive member for driving the rotation of the shift positioning ratchet, a mounting member mounted on a bicycle handlebar, a resettable positioning member, a release member for driving movements of the positioning member, a fixing member connected to the mounting member, and an actuating member for driving the shift positioning ratchet to reversely rotate. The shift positioning ratchet and the actuating member are mounted on the fixing member by a rotatable main shaft, the positioning member is sleeved around the rotatable main shaft, and the positioning pawl engages with the positioning teeth. The drive member is sleeved around the rotatable main shaft and is provided with a driving part engaging with the driving teeth. The bicycle gear shifter has a simple and compact structure, which reduces the stroke of the corresponding components during the shifting process, raises the responsiveness of a bicycle shifting process, and allows a cyclist to shift gears quickly while riding. The invention also allows a cyclist to select a direction of operation on the basis of actual requirements for flexible use.

Claim (Index 1):
A bicycle gear shifter, which is used to drive and release the cable connected to a bicycle derailleur to tighten or release the cable, wherein it comprises a shift positioning ratchet provided with a number of positioning teeth, release teeth and drive teeth, a drive member for driving the rotation of the shift positioning ratchet, a mounting member mounted on a bicycle handlebar, a resettable positioning member, a release member for driving movements of the positioning member, a fixing member connected to the mounting member, and an actuating member for driving the shift positioning ratchet to reversely rotate and for installing the cable;\n the shift positioning ratchet and the actuating member are mounted on the fixing member by a rotatable main shaft, the positioning member is sleeved around the rotatable main shaft, and the positioning pawl engaging with the positioning teeth is provided; the drive member is sleeved around the rotatable main shaft and is provided with a driving part engaging with the driving teeth; when upshifting, the drive part drives the shift positioning ratchet to rotate, which further drives the resettable positioning member to move and achieve the reciprocating linear movements of the positioning member, so that the positioning pawl moving reciprocally and linearly and a number of positioning teeth of the rotating shift positioning ratchet are engaged and positioned; when downshifting, the release member drives the resettable positioning member to move and restricts the moving stroke of the positioning member by the release teeth, thereby achieving the reciprocating linear movements of the positioning member; meanwhile, the actuating member drives the shift positioning ratchet to rotate reversely, so that the positioning pawl moving reciprocally and linearly and a number of positioning teeth of the shift positioning ratchet rotating reversely are engaged and positioned.
