Abstract

The pedalling system has a pedal crank (1) with a ratchet (2), a toothed ring (3) for the ratchet, a chainwheel (4) and a return spring (5) for the pedal crank. The toothed ring is connected to the chainwheel. The right and left side toothed rings are connected to the chainwheel, and the left and right pedal cranks are similar but independent. The pedals are arranged in a slightly inclined position to ease their use. Their drive couplings are combined.

Description

La présente invention concerne un système de pédale à cliquet pourThe present invention relates to a ratchet pedal system for

bicyclette.bicycle.

Traditionnellement, la translation de la bicyclette s'effectue par un tour de pédale complet et pour se faire, le cycliste doit impérativement utiliser ses deux pieds pour assurer la continuité dans la rotation de la pédale qui, dans certains cas, n'est pas aisée, voir même impossible(cas (d'handicapé).  Traditionally, the translation of the bicycle is done by a full pedal turn and to do this, the cyclist must imperatively use his two feet to ensure continuity in the rotation of the pedal which, in some cases, is not easy , see even impossible (case (of disabled).

La pédale, selon l'invention, permet de remédier à ces inconvénients..  The pedal according to the invention overcomes these drawbacks.

Elle est dotée d'un cliquet qui, lors de l'action sur la pédale, engrène avec le plateau d'enté et l'entraîne en rotation sur une certaine course. Dès que l'effort sur la pédale est supprimé, un  It has a pawl which, when the pedal is pressed, meshes with the input plate and drives it in rotation over a certain stroke. As soon as the effort on the pedal is removed, a

ressort de rappel la fait remonter en position initiale pour recevoir la seconde action.  return spring brings it back to the initial position to receive the second action.

deux pieds (sans que ça soit une condition) et d'un seul plateau à chaîne.  two feet (without that being a condition) and a single chainring.

Les dessins annexes, illustrent l'invention comme représentée sur le dessin (2), par action du pied sur la pédale (1), le doigt d'entraînement à cliquet (2) engrène avec le plateau (3) et l'entraîne en rotation. Etant solidaire au premier, le plateau de chaîne entraîne la roue en rotation et par conséquent la  The accompanying drawings illustrate the invention as shown in the drawing (2), by action of the foot on the pedal (1), the ratchet drive finger (2) meshes with the plate (3) and drives it in rotation. Being integral with the first, the chain plate drives the wheel in rotation and consequently the
