Title: Pedal and bottom bracket assembly for a cycle
IPC: B62M3/00
Filed: 1989-06-30
Abstract: In accordance with article 49 in the "bicycle" regulations, this pedal and bottom bracket assembly, characterised by a lever arm 7 of profiled cross-section and double wall 8 can be distinguished from the conventional pedal and bottom bracket assembly by the centre of gravity systematically moving away from its fulcrum O<1> (axis of the pedal and bottom bracket assembly). This pedal and bottom bracket assembly can thus substitute for the radial force O<2> a part of its energy which it adds to the attractive forces of the movement 6. As a consequence, the kinetic energy of translation promotes "pedalling" by more rational use of the useful tangents included in the rotational forces and this "stimulus" enhances the efficiency because it is physically embodied in all the pedalling times ... included in the "negative" area of the neutral points ... hence "greater efficiency". This pedal and bottom bracket assembly according to the invention is particularly intended to enhance the pleasure in practising cycling, in all the variants of pastime and competition cycling.
