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.
Cijoint : les dessins illustrant l'invention
La figure 1 représente l'appareil vu côté extérieur avec l'emplacement de la manivelle déporté de 45 degrés environ en avant par rapport à la canalisation interne qui se trouve marquée par un pointillé avec son orifice étanche de remplissage
La figure 2 représente une variante en coupe de l'appareil
La figure 3 représente l'appareil en coupe avec sa canalisation interne Cijoint: the drawings illustrating the invention
Figure 1 shows the device seen on the outside with the location of the crank offset about 45 degrees forward relative to the internal pipe which is marked by a dotted line with its sealed filling orifice
Figure 2 shows a sectional variant of the device
Figure 3 shows the device in section with its internal pipe
