Bicycle brake and shift operating device

摘要

A bicycle brake and shift operating device is provided with a bracket, a brake operating member, a shift operating unit and a pawl releasing member. The brake lever is pivotally attached to the bracket at a pivot axis. The shift operating unit includes a takeup member pivotally mounted relative to the bracket and a locking pawl pivotally mounted relative to the bracket. The locking pawl moves between a locking position and a release position. The pawl releasing member pivots relative to the bracket to pivot. The pawl releasing member selectively locates the locking pawl from the locking position to the release position by pivoting around the third pivot axis. The pivot axis of the pawl releasing member is offset from both of the pivot axes of the takeup member and the locking pawl.

主权项

1. A bicycle brake and shift operating device comprising:
a bracket including a grip portion; a brake operating member pivotally attached to the bracket at a pivot axis; a shift operating unit including a takeup member pivotally mounted relative to the bracket to pivot on a first pivot axis and a locking pawl pivotally mounted relative to the bracket to pivot on a second pivot axis, with the locking pawl being movably arranged to pivot on the second pivot axis in a first rotational direction about a first pivot pin from a locking position in which the locking pawl holds the takeup member to a release position in which the locking pawl releases the takeup member; and a pawl releasing member pivotally mounted relative to the bracket to pivot on a third pivot axis, with the pawl releasing member selectively locating the locking pawl from the locking position to the release position by pivoting around the third pivot axis in the first rotational direction about a second pivot pin, an entirety of the second pivot pin being spaced from the first pivot pin along a direction parallel to the third pivot axis; the third pivot axis of the pawl releasing member being offset from both of the first and second pivot axes of the takeup member and the locking pawl, and a first distance between the first and third pivot axes being smaller than a second distance between the first and second pivot axes.
