Filed:

Mar 19, 2003

Appl. No.:

10/394094

Inventors:

Thomas Ritchey - Palo Alto CA, US

Assignee:

RITCHEY DESIGNS, INC. - Redwood City CA

International Classification:

F16C001/12

US Classification:

074/501600

Abstract:

A barend mounted twist shifter provides for ergonomic shifting and eventual brake actuation. The barend, which commonly provides an ergonomic hold on position for a bike rider's hands at the peripheral handlebar ends provides for an attaching location for the inventive twist shifter. Consequently, a bike rider may operate the bike's derailleur without taking his hands from the barends. A brake actuator may be combined with the twist shifter. The shifter's spool around which the shifter cable coils, may be positioned in the assembly adjacent the barend's tip. Its minimum diameter is substantially independent from the barend's outside diameter and may be reduced such that the actuation torque on the gripdrum may be lowered as well. The gripdrum and spool may be combined with a ratchet mechanism that may be easily integrated in the shifter's housing adjacent the barend's tip. A thumb perch serves as a release for down shifting.
