Abstract

The invention concerns a device enabling a pedal (3) with mechanical attachment (3) to be integrated on the end piece of a connecting rod (2). The other end of the connecting rod (2) comprises the ball bearing (1) and fixture for rotating the device on the crank (4) of the bicycle. For an easy fit of the shoe, a large forward connecting rod (2) pedal (3) tilting effect resulting from the center of gravity must be corrected with a flexible shank (5) fixed on the pedal (3) contacting the heel of the shoe and urged to rise to the front attachment (3) of the pedal (3). The connecting rod (2) enables the pedal attachment (3) to be positioned horizontally at the high point of the crank (4) at about 40 mm forward and 23 mm lower while remaining in an advanced position throughout the forward phase of the cycle.

Description

SYSTEME DE TRAmTORMATION D'UNE PEDALE DE VELO TRAMTORMING SYSTEM OF A BIKE PEDAL
La présente invention concerne un dispositif permettant à une pédale (3) de vélo à accrochage (3) mécanique de se monter soudée sur une biellette. (2)The present invention relates to a device for a pedal (3) bike attachment (3) mechanical mount welded to a rod. (2)
L'autre extrémité de la biellette (2) comporte le roulement (1) et fixation faisant tourner le dispositif sur la manivelle (4) du vélo. L'ensemble pédale (3) biellette (2) sera finalisé en une seule pièce hormis les pièces mobiles de l'accrochage. Le plan horizontal de la pédale (3) maintenu par le pied et la biellette (2) forment un angle vers l'avant d'environ 145°.The other end of the link (2) comprises the bearing (1) and fixing rotating the device on the crank (4) of the bicycle. The pedal assembly (3) rod (2) will be finalized in one piece except the moving parts of the attachment. The horizontal plane of the pedal (3) held by the foot and the rod (2) form a forward angle of about 145 °.
Entre le roulement (1) sur l'embout de la manivelle (4) et l'axe initial de la pédale (3), l'entre-axe est de 45mm.Between the bearing (1) on the tip of the crank (4) and the initial axis of the pedal (3), the center distance is 45mm.
La biellette (2) permet donc à l'accrochage de la pédale (3) de se positionner, imposé par le pied, à l'horizontale au point haut de la manivelle (4) à environ 40mm vers l'avant et de 23mm plus bas et reste avancé tout au cours de la phase avant.The rod (2) allows the attachment of the pedal (3) to position itself, imposed by the foot, horizontally at the high point of the crank (4) about 40mm forward and 23mm more down and remains advanced throughout the prior phase.
En effet si la pédale (3) reste positionnée horizontalement vers l'avant tout au cours de la phase avant, au point bas de la manivelle (4) les dimensions sont les mêmes qu'en haut et construisent un temps mort.Indeed if the pedal (3) remains positioned horizontally forward during the whole phase before, at the low point of the crank (4) the dimensions are the same as above and build a dead time.
La phase avant (motrice) est donc plus courte et plus puissante que le cycle standard.The forward phase (motor) is therefore shorter and more powerful than the standard cycle.
Toutes ces dimensions peuvent être variables.All these dimensions can be variable.
Pour corriger un important effet de bascule vers l'avant dû au centre de gravité, biellette (2) pédale (3) , une queue (5) flexible fixée sur la pédale (3) touchant le talon de la chaussure vient remonter l'accrochage avant de la pédale (3) afin de pouvoir chausser aisément.To correct an important effect of rocking forward due to the center of gravity, rod (2) pedal (3), a tail (5) flexible fixed on the pedal (3) touching the heel of the shoe comes up the hooking before the pedal (3) in order to easily fit.
La semelle rigide de la chaussure maintient parfaitement la pédale horizontale. Le cycliste n'enregistre aucune gène, trouve un confort certain, retrouve une meilleure fluidité dans le cycle par le retour du pied plus léger sur la phase arrière, un passage du point mort haut plus court et un gain de couple sur la phase motrice.The rigid sole of the shoe perfectly holds the horizontal pedal. The cyclist does not register any gene, finds a certain comfort, finds a better fluidity in the cycle by the return of the lighter foot on the rear phase, a passage of the top dead center shorter and a gain of torque on the driving phase.
La nouveauté du dispositif se caractérise par cet important effet de bascule vers l'avant donnant de larges dimensions . The novelty of the device is characterized by this important effect of rocking forward giving large dimensions.
