CA 2215432

By observing the movement of a pedaler's leg, it is apparent that the leg exactly follows the circular movement of the crankset, a situation that creates problems in terms of crankset mechanics and ergonomic design. The purpose of this invention therefore is to present a crankset whose resulting strength is increased by the internal mechanics and by a better ergonomic design. The purpose of this invention is to present a more ergonomic crankset, the form of movement being oval or, ultimately, rectilinear, as opposed to the circular movement observed in the case of conventional cranksets.

Lorsque l'on étudie le mouvement de la jambe d'un pédaleur ,l'on s'apercoit qu'il subit très exactement celui ,circulaire , du pédalier, cet état de fait ayant des lacunes tout autant de point de vue de la mécanique du pédalier que du point de vue ergonomique. La présente invention a donc pour but de présenter un pédalier dont la force résultante est augmentée par la mécanique interne et par une meilleure configuration ergonomique. En effet, la présente invention a pour but de présenter un pédalier plus ergonomique, la forme du mouvement étant ovale ou à la limite rectiligne, par opposition à ronde pour lespédaliers conventionnels.
