Abstract
Abstract In this dual control of bicycle brakes the main or racing lever and the auxiliary or sports lever are rigidly interconnected through a common fulcrum pin. The main lever and the auxiliary lever each comprise, in the portion connected to the brake lever fulcrum bracket, a polygonal hole or eye adapted to receive therethrough a fulcrum pin having a matching cross-sectional polygonal contour, so that the levers and pin are rotatably rigid with one another, rings also formed with a corresponding polygonal hole being adapted to be fitted on the fulcrum pin and having a cylindrical outer peripheral contour such that the fulcrum pin is pivotally mounted therethrough in a bearing provided to this end in the brake lever fulcrum bracket.

Claim 1
Independent Claim
128 words
Brake control apparatus for a bicycle having a handbrake, said brake control apparatus comprising a bracket secured to the handlebar of the bicycle, first and second separate levers of different shape for effecting brake control, an axle having a polygonal cross-section, said first and second levers having respective holes corresponding in shape to that of the polygonal cross-section of the axle, said first and second levers being closely fitted on said axle by means of said holes so as to be coupled therewith in rotation, and rings having holes of the same shape as the cross-section of the axle and receiving the axle for common rotation therewith, said rings having cylindrical outer surfaces rotatably mounted in said bracket and serving as bearings for said axle in the bracket.
