Bicycle pedal assembly, has three crankarms in which one of crankarms is rotated around axle of assembly, other crankarm is provided with three fixation axles, and third crankarm maintains rear end of former crankarm in its movement

摘要

#CMT# #/CMT# The assembly (5) has a crankarm (1) rotated on 360 degree around an axle (4) of the assembly and possessing reduced length ranging from 5 to 6 centimeters. Another crankarm (2) has three fixation axles in which one axle situated at the front forms a support axle of the assembly, other axle ensures fixation on the crankarm (1) and the third axle situated at the rear ensures fixation on a lower end of a third crankarm (3), where the crankarm (2) possesses length of 10 centimeter. The crankarm with length ranging from 15 to 20 centimeter, maintains a rear end of the crankarm (2) in its movement. #CMT#USE : #/CMT# Pedal assembly for a bicycle. #CMT#ADVANTAGE : #/CMT# The crankarms permit to modify and displace the assembly trajectory in front of the axle of the assembly, thus permitting to use the effort provided by a cyclist, in an efficient and comfortable manner, and with reduced fatigue. The assembly can be manufactured in a simple and inexpensive manner. The assembly has reduced encumbrance. The assembly permits to improve top dead center passage of the assembly for ensuring efficient and comfortable regularity of the movement. The assembly permits to increase extension of a lever arm in front of the axle of the assembly, while improving comfort of the cyclist. The assembly permits to reduce amplitude of horizontal displacement of the assembly while maintaining amplitude of vertical displacement of the assembly to 34 centimeter. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a right view of a bicycle pedal assembly with a support beam that supports three crankarms on a frame tube. 1-3 : Crankarms 4 : Axle 5 : Bicycle pedal assembly 6 : Frame tube 7 : Support beam 9 : Plates.
