Embodiment Construction

[0020]FIGS. 1-7 illustrate a bicycle control apparatus 10 mountable to a handlebar 12 according to one embodiment of the present invention. The bicycle control apparatus 10 generally includes a housing 18, a shift lever assembly 21 and a brake lever assembly 23. The housing 18 is mountable to a handlebar 12, typically a drop-style handler found on a road bike. Looking to FIGS. 1 and 2, the handlebar 12 includes an upper portion 13 extending across the bicycle frame (not shown), a curved portion 15 extending downward from the upper portion, and a lower portion 17 extending rearward toward the rider. The curved portion 15 and the lower portion 17 are commonly referred to as the “drops.” The housing 18 is typically mounted to the curved portion 15 of the handlebar 12 by a clamp 14 and a bolt 16.

[0021] The shift lever assembly 21 pulls or releases a control cable 11 connected to gear change mechanism (not shown) to shift between various gear positions. The gear change mechanism may be ...

Abstract

A bicycle control apparatus configured to allow a rider to effect a release gear shift without releasing his grip from the handlebar. The bicycle control apparatus includes a brake lever and a shift lever wherein the shift lever is moveable in a first direction to perform a release shift operation and movable in a second direction toward the handlebar independently of the brake lever.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation-in-part of application Ser. No. 10 / 906,730 filed on Mar. 3, 2005 entitled Bicycle Shifter.BACKGROUND OF THE INVENTION [0002] The present invention relates to a bicycle control apparatus, and more particularly, to a bicycle control apparatus having a brake lever and a shift lever wherein the shift lever is movable in a first direction to perform a shift operation and movable in a second direction toward the handlebar independently of the brake lever. [0003] Some bicycle road shifters position a release shift lever behind the brake lever, the shift lever being actuable inboard toward the bicycle frame to effect a cable unwinding or release operation. A disadvantage found in some such designs is that although the release shift lever is configured to pivot rearwardly toward the handlebar with the brake lever, the shift lever is not configured to pivot rearwardly independently of the brake lever. This preve...
