Abstract

Device intended to reduce the negative effects of the top dead centre and bottom dead centre points which the cyclist is subjected during pedalling. The invention relates to a device which can be fitted on to one of the pedalling cranks. This device consists of a disc 1 of approximately 380 millimetres diameter into which is built a channel 2 of ovoid shape offset by approximately 45 degrees to the rear of the crank. In this channel there circulates a high-density liquid 3 the objective of which is, in a first instance, to compensate for the negative effects produced by the dead centre points. In a second instance, at a high pedalling rate, the liquid, being thrown to the ends of the channel, generates the inertia phenomenon giving an increase in efficiency.

Description

DISQUE D'ASSISTANCE DE PéDALAGE
DESCRIPTION
La présente invention concdrne un appareil adaptable sur la manivelle de pédalier d'une bicyclette dans le but d'améliorer le mouvement de pédalage.PEDAL ASSISTANCE DISC
DESCRIPTION
The present invention relates to an apparatus adaptable to the crank of a bicycle with the aim of improving the pedaling movement.

Lors du mouvement tournant imposé par le pédalage, il. existe une période pendant laquelle le cycliste transmet difficilement son énergie au mécanisme d'entrainement de la bicyclette.During the rotating movement imposed by pedaling, it. There is a period during which the cyclist hardly transmits his energy to the drive mechanism of the bicycle.

Cette période se réalise lorsque, une des pédales est en haut et l'autre en bas c'est le point mort haut et bas PM HB
Selon l'invention l'appareil présente les particularités suivantes
Pour l'esthétique, il est de forme ronde ayant l'aspect d'un disque d'un diamètre correspondant eu cercle décrit par le mouvement tournant de la manivelle de pédalier, et d'une épaisseur limitéepar l'emplacement disponible au montage qui doit permettre une liberté de fonctionnement.This period is realized when, one of the pedals is at the top and the other at the bottom is the top and bottom dead center PM HB
According to the invention the device has the following features
For aesthetics, it is round in shape having the appearance of a disc of a diameter corresponding to the circle described by the rotating movement of the crank, and of a thickness limited by the space available for mounting which must allow freedom of operation.

Ce disque réalisé en matière légère et rigide genre carbone, est fixé sur la manivelle côté cadre.This disc made of light and rigid carbon-like material, is fixed to the crank on the frame side.

A l'intérieur du disque une canalisation de forme ovoïde est réservée pour la circulation d'un liquide de très haute densité qui, par le mouvement tournant du disque, se déplace et de ce fait se trouve dans une position préférentielle au moment du PM HB
La pression exercée par le cycliste a une double action
10 Faire avancer la bicyclette
20 Faire remonter le liquide à une hauteur réduite au minimum pour
aussitôt basculer en avant afin d'augmenter la pression au moment
où le cycliste arrive. en fin de puissance et ainsi de suite à
chaque tour de manivelle.Inside the disc, an ovoid-shaped pipe is reserved for the circulation of a very high density liquid which, by the rotating movement of the disc, moves and is therefore in a preferential position at the time of PM HB.
The pressure exerted by the cyclist has a double action
10 Advancing the bicycle
20 Raise the liquid to a height reduced to a minimum to
immediately tilt forward to increase pressure when
where the cyclist arrives. at the end of power and so on
each turn of the crank.

A régime de pédalage élevé, il apparaît un effet d'inertie qui apporte un supplément d'éfficacité particulièrement interessant pour les cyclistes pratiquant la compétition.At a high pedaling speed, there appears an inertia effect which brings an additional efficiency particularly interesting for cyclists practicing competition.
