#CMT# #/CMT# The pedal mechanism, designed to be used by a rider in an upright position, consists of a shaft (2) driven by two pedals (60) via a transmission mechanism with cranks (3, 53, 11, 61), levers (5, 57) and pivots (6, 8, 14, 56, 58, 64) that give each pedal a higher mean speed at the top of its trajectory than the bottom. The pedal trajectories have virtually equal horizontal and vertical dimensions, and they drive the shaft at a constant speed. #CMT#USE : #/CMT# Pedalling a cycle or exercise machine in an upright position. #CMT#ADVANTAGE : #/CMT# The transmission system reduces vertical oscillation of rider's centre of gravity. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the transmission system and one of the pedals. 2 : Driven shaft 3, 53, 11, 61 : Cranks 7, 57 : Levers 6, 8, 14, 56, 58, 64 : Pivots 60 : Pedal. |
