This is to keep the ankle of the pedaling rider to comply with the crank rotation angle.

Abstract

L'invention a pour objet de convertir en puissance de rotation un effort de pédalage gaspillé sans avoir été transformé en énergie de rotation, en limitant la rotation des axes de pédale d'une bicyclette, de telle sorte qu'un point d'impulsion de l'effort de pédalage puisse se déplacer vers les extrémités avant d'un corps de pédale au lieu d'aller vers un axe de pédale, ce qui permet de changer la direction d'impulsion au point mort. Ainsi, lorsqu'une bicyclette arrêtée, qui n'a pas encore produit d'énergie inertielle, est mise en marche, ou lorsqu'il y a lieu de créer une puissance de rotation par le seul effort de pédalage en montée ou analogue avec disparition de l'énergie inertielle, l'effort de pédalage peut être transformé en puissance de rotation, même dans une zone de point mort. En outre, dans le cas où la rotation de l'axe de pédale, qui a été limitée pour en augmenter la puissance, doit être modifiée en rétropédalage pour éviter divers risques ou obstacles accidentels sur la chaussée, ou lorsque la rotation de l'axe de pédale empêche de rouler en descente ou à vitesse élevée ou analogue, la limitation de la rotation de l'arbre de pédale est levée pour assurer une rotation libre de l'axe de pédale dans les deux sens, ce qui permet de rouler en toute sécurité.
