Abstract
A shift and brake lever assembly including a brake lever having a first surface facing a handlebar and a second surface facing away from a handlebar. A shift lever may be mounted to the second surface of the brake lever using mounting components. Complementary apertures of the various mounting components may lie on a common longitudinal axis.
Claims20
A control device for mounting on a bicycle handlebar, the control device comprising:
- a rotatable brake lever adapted to be attached to a drop-style handlebar of a bicycle and defining a first axis of rotation, wherein rotation of the brake lever about the first axis of rotation is configured to move an elongate control portion of the brake lever generally toward and away from the handlebar within a brake lever plane;
- wherein the control portion of the brake lever defines a proximal side generally closer to the handlebar and a distal side generally further from the handlebar;
- and
- a rotatable shift lever adapted to be operatively connected to the brake lever and disposed on the distal side of the control portion of the brake lever, the shift lever defining a second axis of rotation substantially perpendicular to the first axis of rotation, and wherein the shift lever may be rotated by hand through a plurality of operating positions without movement of the brake lever;
- wherein each operating position of the shift lever corresponds to a gear of the bicycle, and wherein the shift lever is configured to be rotated in a first direction to cause a shift into a smaller gear, and to be rotated in a second direction to cause a shift into a larger gear;
- and
- wherein the shift lever is configured to be mechanically held in a selected one of the operating positions after being rotated.

A control device for mounting on a handlebar of a bicycle, the control device comprising:
- a rotatable brake lever adapted to be fixed to the handlebar and defining a first axis of rotation, wherein rotation of the brake lever about the first axis of rotation is configured to move a control portion of the brake lever generally toward and away from the handlebar within a brake lever plane;
- and
- a rotatable shift lever adapted to be fixed to the brake lever on a distal side of the brake lever relative to a frame of the bicycle and defining a second axis of rotation oriented at an angle between 70 degrees and 110 degrees relative to the first axis of rotation;
- wherein the shift lever is a mode-switchable lever including means for operating selectively in either an index mode or a friction mode.

A control device for mounting on a drop-style handlebar of a bicycle, the control device comprising:
- a lever support structure configured to attach securely to the handlebar;
- a first pivot axis disposed at an upper region of the lever support structure;
- a brake lever pivotably connected to the lever support structure through the first pivot axis, the brake lever including an elongate control portion defining an inner brake lever surface configured to face generally toward the handlebar and an outer brake lever surface configured to face generally away from the handlebar;
- a second pivot axis disposed at the upper region of the lever support structure in proximity to the first pivot axis;
- and
- a shift lever pivotably connected to the lever support structure through the second pivot axis, the shift lever including an elongate control portion defining an inner shift lever surface facing generally toward the handlebar and the brake lever, and an outer shift lever surface facing generally away from the handlebar and the brake lever;
- wherein the brake lever is configured to be rotated by hand through a range of operating positions within a brake lever plane;
- and
- wherein the shift lever is configured to be rotated by hand through a range of operating positions within a shift lever plane substantially perpendicular to the brake lever plane, and to be held in place by friction at each operating position.
