Abstract:
A combination gear-shift, brake, and electric display control device for a bicycle having a handlebar, the device comprising:a support body locatable on the handlebar and having spaced apart sidewalls and a central axis extending between the sidewalls; an elongated brake lever pivotably attached to the support body about a first pivot axis that is substantially perpendicular to the central axis; an indexing ratchet rotatably mounted within the support body about a second pivot axis substantially aligned with the central axis to define a plurality of operating positions for a pulley adapted to wind a gear control cable; a first gear-control lever located under the elongated brake lever and being rotatable about the second pivot axis, whereby the first gear-control lever is movable in a direction substantially orthogonal to a motion path of the elongated brake lever to rotate the indexing ratchet in a first direction; a second gear-control lever, extending in a direction substantially perpendicular to the elongated brake lever and the first gear-control lever, projecting from a selected sidewall of the support body, the second gear-control lever being rotatable about the second pivot axis to rotate the indexing ratchet in a second direction, opposite from the first direction; and, an independent electric switch body mounted within the support body on the selected sidewall with an associated control button projecting through the selected sidewall approximately midway between the second gear control lever and a portion of the support body adapted to abut the handlebar; and an electric cable operationally connected to the independent electric switch body and the electric display.
