Abstract

Crank 1 comprises a pin 13 which has a symmetrical hole 14 into which the similarly symmetrical body supporting pedal 16 is keyed, with the axis of rotation of the said pedal being eccentric with respect to the said body. Rotation of the said body by half a turn increases or decreases the position of the pedal with respect to the crank, varying its length. In addition to this the head 5 of the crank is attached to the frame 3 of the movement eccentrically with respect to axis A through an interposed shim 2. The length of the crank changes in relation to the position of the shim. Where the chain wheel spokes are incorporated, reference and fixing diameters for the eccentric chain wheel 8, 9 are provided. <IMAGE>
