Abstract

Bicycle pedal-crank mechanism. There are one, two or three flexible parts; namely the plate, (sprocket) the cranks, the spindle. It may be used on any bicycle.

Description

BESCRIPTION
Cette invention concerne un type de modifications à apporter au pedalier de la bicyclette pour diminuer l'effet de point mort et faciliter le pédalage.BESCRIPTION
This invention relates to a type of modification to be made to the bicycle crankset to reduce the neutral effect and facilitate pedaling.

L'état de la technique dans le secteur considéré est bien connu. Cette invention vise à accroître les performances du cycliste.The state of the art in the sector considered is well known. This invention aims to increase the performance of the cyclist.

Plateau régulateur
Ce plateau est monté de manière à pouvoir tourner librement autour de l'axe, même quand les manivelles sont immobiles (par exemple,le plateau est monté sur roulements à billes,ou sur l'axe du pédalier, ou sur la manivelle droite, ou sur le cadre même de la bicyclette) et ce plateau est entraîné à tourner par une liaison plastique entre les manivelles et lui (par exemple un ou plusieurs ressorts à lamelles fixés le long de la manivelle droite et se prolongeant de l'autre côté de l'axe, ces prolongements étant liés au plateau par des blocs de caoutchouc)
Plateau régulateur $autre modèle) est un plateau dans lequel les rayons AA', BB', CC',... sont des ressorts i lamelle - disposés de manière à rester,lors de leur flexion, dans le plan du plateau - soudés, ou fixés à l'aide de visses, aux points A, B, C,.Regulator plate
This plate is mounted so that it can rotate freely around the axis, even when the cranks are stationary (for example, the plate is mounted on ball bearings, or on the crankset axis, or on the right crank, or on the bicycle itself) and this plate is rotated by a plastic connection between the cranks and it (for example one or more leaf springs fixed along the right crank and extending on the other side of the axis, these extensions being linked to the plate by rubber blocks)
Regulator plate $ other model) is a plate in which the spokes AA ', BB', CC ', ... are leaf springs - arranged so as to remain, during their bending, in the plane of the plate - welded, or fixed with screws, at points A, B, C ,.

- liés à la couronne dentée par des blocs de caoutchouc (silent-bloc) aux points A', B', C'
Manivelle pliante
Si l'on remplaçait purement et simplement la manivelle AB par un ressort à malelle, alors l'axe de la pédale ne se déplacerait malheureusement plus nécessairement parallèlement à l'axe du pédalier. Aussi le segment AB de- la manivelle pliante se com- pose-t~il de deux segments AC et CB,pas nécessairement égaux, articulés en C (par exemple par un roulement à bilames de mamière à ce que le plan ACB soit parallèle au plan du plateau et ces deux morceaux AC et CB sont liés entre eux par une liais on élastique (par exemple un ou plusieurs ressorts à lamel- les fixés le long de chacun des deux morceaux et des blocs de caoutchouc)
Axe souple
L'axe du pédalier est remplacé par un gros ressort à lamelle pouvant se tordre, c'est à dire que, l'une des manivelles étant fixée, l'autre pourrait encore tourner un peu. - linked to the ring gear by rubber blocks (silent-block) at points A ', B', C '
Folding crank
If one replaced purely and simply the crank AB by a spring with malelle, then the axis of the pedal unfortunately would no longer necessarily move parallel to the axis of the crankset. Also the segment AB of the folding crank is made up of two segments AC and CB, not necessarily equal, articulated in C (for example by a bimetallic bimetallic bearing so that the plane ACB is parallel to the plane of the plate and these two pieces AC and CB are linked together by an elastic link (for example one or more springs with nipples- fixed along each of the two pieces and rubber blocks)
Flexible axle
The axle of the crankset is replaced by a large leaf spring which can twist, that is to say that, one of the cranks being fixed, the other could still turn a little.

Claims (1)

REVENDICATIONS Dispositif flexible caractérisé par le fait que le pédalier emmagasine de l'énergie quand le couple qui le fait tourner augmente suffisamment et restitue ensuite cette énergie (avant que le couple ne redevienne maximum). Tout couple moteur irrégulier pouvant entre ainsi réguld,cette invention ne se limite donc pas forcément au pédalier de bicyclette. Flexible device characterized by the fact that the crankset stores energy when the torque which turns it increases sufficiently and then restores this energy (before the torque becomes maximum again). Any irregular motor torque that can thus be regulated, this invention is therefore not necessarily limited to the bicycle crankset.
