Abstract
A control device is configured to be attached to the handlebar of a bicycle for controlling a brake mechanism and change speed mechanism. The control device comprises a bracket fixed to the handlebar, a brake lever pivotally coupled crosswise relative to the bracket and a release lever. The brake mechanism is controlled by fore and aft pivotal movement of the brake lever, while the change speed mechanism is controlled by sideways pivotal movement of the brake lever and the release lever. The brake lever and the release lever are further configured relative to the bracket for smooth easy operation by the rider.
Claims25
A bicycle control device comprising:
- a support member having a mounting portion configured and arranged to be coupled to a bicycle handlebar and a distal end longitudinally spaced from said mounting portion;
- a cable winding mechanism coupled to said support member, and having a cable attachment point;
- and
- a control lever operatively coupled to said cable winding mechanism, said control lever including an attachment end portion and a shift operating portion extending outwardly from said distal end of said support member,
- said attachment end portion of said control lever being pivotally coupled to said support member to move between a rest position and a shifting position about a shift pivot axis that extends longitudinally between said mounting portion and said distal end, and
- said shift operating portion of said control lever being configured and arranged to be disposed along a line that is angled relative to said shift pivot axis by approximately an angle between forty-five degrees and fifty-five degrees at said rest position and that passes through said attachment end portion at said shift pivot axis.

A bicycle control device comprising:
- a support member having a mounting portion configured and arranged to be coupled to a bicycle handlebar;
- a cable winding mechanism coupled to said support member, and having a cable attachment point;
- and
- a brake/shift lever operatively coupled to said cable winding mechanism, said brake/shift lever including an attachment end portion and a brake/shift operating portion extending outwardly from said support member,
- said attachment end portion of said brake/shift lever being pivotally coupled to said support member about a shift pivot axis to move between a rest position and a shifting position, said attachment end portion of said brake/shift lever further being pivotally coupled relative to said support member about a brake pivot axis that is angled relative to said shift pivot axis, and
- said shift operating portion of said brake/shift lever being configured and arranged to be disposed along a line that is angled relative to said shift pivot axis by approximately an angle between forty-five degrees and fifty-five degrees at said rest position and that passes through said attachment end portion at said shift pivot axis.
