Method for operation of bicycles and similar using two lever arms to generate a torque has two free wheel hubs between levers and shaft, to generate a torque within selected lever angle, and turn shaft in one direction only

摘要

During energy conversion, two lever arms (1,2) are operated alternately via free wheel hubs (4,5) and a transmission, to generate a toque within a lever angle of 0degrees and 180degrees, pref. between 55degrees and 95degrees. The energy is transmitted to a drive shaft (3) for rotation in one direction only. Bevel gears (6,8) connected to the lever arms are moved via a further gear (7), so that the lever arms move up and down alternately.
