INVENTIONINVENTION
Le but de cette invention est de proposer aux cyclistes un dispositif nouveau, de manivelles de pédalier de bicyclette, télescopiques, à longueur variable, et ajustables en marche, au choix du cycliste en fonction de ses possibilités physiques, eu égard aux difficultés rencontrées sur le profil du terrain à parcourir. Il a ainsi à sa disposition, sans descendre de bicyclette, des longueurs de manivelles de pédalier, qui auparavant faisait l'objet d'un choix empirique, un peu comme un compromis à l'estimation, sans tenir compte de tous les paramètres entrant en ligne de compte, alors que l'on se déplace en bicyclette. The object of this invention is to provide cyclists with a new device, bicycle crank cranks, telescopic, variable length, and adjustable in operation, the choice of the cyclist according to its physical capabilities, given the difficulties encountered on the bike. profile of the field to go. He thus has at his disposal, without descending a bicycle, lengths of pedal cranks, which previously was the subject of an empirical choice, a bit like a compromise to the estimate, without taking into account all the parameters entering into line of account while riding a bicycle.
Pour obtenir ce résultat, les manivelles proposées ci- dessous, se substituent aux manivelles à longueur fixe, bloc qui équipe les bicyclettes actuelles et dont le choix de la longueur est sûrement empirique. To achieve this result, the cranks proposed below, replace the fixed-length cranks, block that equips the current bicycles and whose choice of length is surely empirical.
Les manivelles faisant l'objet de l'invention, sont constituées d'un corps de base rep. 1 figure 4 lequel est fixé sur l'axe du pédalier de manière classique, sur carré normalisé, dans lequel coulisse la 2eme partie de la manivelle rep. 2 figure 4, et porte le trou taraudé, gauche ou droit pour recevoir la pédale. Un ressort de rappel rep. 7 fig. 4, rappelle le coulisseau rep. 2 vers le haut. Un verrou rep. 3 fig. 4, permet au cycliste de faire varier la longueur de la manivelle selon son choix. The cranks forming the subject of the invention consist of a basic body rep. 1 Figure 4 which is fixed on the axis of the pedal in a conventional manner, on standard square, in which slides the 2nd part of the crank rep. 2 figure 4, and carries the tapped hole, left or right to receive the pedal. A return spring rep. 7 fig. 4, recall the slider rep. 2 up. A lock rep. 3 fig. 4, allows the cyclist to vary the length of the crank according to his choice.
Pour rallonger la longueur les deux manivelles, droite et gauche, il suffit au cycliste de mettre sa pédale en fonction basse. Puis actionner le levier de verrouillage- déverrouillage rep. 3 fig. 4, puis appuyer sur la pédale, en relâchant le levier 3 fig. 4 la manivelle intéressée se verrouille en fonction basse. Un jeu de course bas évite à la partie télescopique de quitter son logement rep. 5 fig. 4 Pour raccourcir la longueur des deux manivelles, droite et gauche, il suffit au cycliste de mettre sa pédale en position haute, puis actionner le levier de verrouillage-déverrouillage rep. 3 fig. 4 et d'accompagner le retrait, le ressort de rappel rep. 3 fig. 4 raccourcira automatiquement la longueur de la manivelle, en relâchant le levier de verrouillage-déverrouillage rep. 3 fig. 4, la manivelle sera en fonction verrouillée basse. To lengthen the length of the two cranks, right and left, it is enough for the cyclist to put his pedal in low function. Then actuate the lock-unlock lever rep. 3 fig. 4, then press the pedal, releasing the lever 3 fig. 4 the crank concerned locks in low function. A low racing game prevents the telescopic part from leaving its housing rep. 5 fig. 4 To shorten the length of the two cranks, right and left, the cyclist only needs to put his pedal in the up position, then press the lock-unlock lever rep. 3 fig. 4 and accompany the withdrawal, the return spring rep. 3 fig. 4 will automatically shorten the length of the crank, releasing the lock-unlock lever pos. 3 fig. 4, the crank will be locked down.
Le verrou de verrouillage-déverrouillage, faisant l'objet des figures 5A et 5B, comprend un levier actionnant un verrou, qui vient, par la force d'un ressort, actionner une bille, d'avant en arrière, bloquer ou libérer la partie mobile, porteuse de la pédale, qui coulisse dans le corps rep. 1 fig. 4. Sur cette partie mobile, cylindrique, sont usinées deux encoches, dans lesquelles la bille vient se loger pour assurer l'immobilité et assurer le verrouillage, dans l'une ou l'autre position. L'extrémité du verrou porte une rampe inclinée, sur laquelle circule à bille, ce plan incliné amplifie l'effet du ressort. Le dispositif est complété par un fin de course haute et basse, constitué par une goupille rep. 5 fig. 4, qui autour de laquelle coulisse la partie mobile cylindrique télescopique porte pédale rep. 2 fig. 4 et dans laquelle une lumière ovale a été usinée à la cote de la course maxi mini désirée. The locking-unlocking lock, which is the subject of FIGS. 5A and 5B, comprises a lever actuating a lock, which comes, by the force of a spring, to actuate a ball, from front to back, to block or to free the part mobile, carrier of the pedal, which slides in the body rep. 1 fig. 4. On this mobile part, cylindrical, are machined two notches, in which the ball is housed to ensure immobility and ensure locking in one or the other position. The end of the lock carries an inclined ramp on which ball, this inclined plane amplifies the effect of the spring. The device is completed by a high and low end of stroke, constituted by a pin rep. 5 fig. 4, which around which slides the mobile part telescopic cylindrical pedal holder rep. 2 fig. 4 and in which an oval light has been machined to the dimension of the desired maximum mini stroke.
Le cycliste a ainsi le choix de la longueur de ses 60 manivelles à tout moment afin de mieux doser ses efforts, face au profil de la route et aux difficultés rencontrées. Exemple: le vent violent contraire, et surtout sans perte de temps, sans descendre de machine et sans outil. De mieux profiter de son style de pédalage, certains préfèrent mouliner court et rapidement, manivelles courtes; d'autres préférant tirer long manivelles longues, mais en se gardant la possibilité du choix. The cyclist has the choice of the length of his 60 cranks at any time to better balance his efforts, facing the profile of the road and the difficulties encountered. Example: the opposite violent wind, and especially without loss of time, without descending machine and without tools. To better enjoy his pedaling style, some prefer to short and short winding, short cranks; others prefer to pull long long cranks, but keeping the possibility of choice.
Cet équipement de manivelles télescopiques à longueur variable, vient en complément des équipements classiques sur une bicyclette. Il est à tenir compte que ce dispositif permet d'envisager, sinon deux longueurs de manivelles de pédaliers, mais plusieurs si nécessaires, tout en respectant le même procédé. This telescopic crank equipment with variable length, comes in addition to conventional equipment on a bicycle. It should be taken into account that this device makes it possible to envisage, if not two lengths cranks cranks, but several if necessary, while respecting the same process.
C'est par mesure de simplification et clarté de l'exposé qu'il a été choisi deux longueurs de manivelles télescopiques, le principe de variation de longueur par un système télescopique, permet si besoin un étalonnage de longueurs infinies. Les manettes de commande sont placées sur le corps principal des manivelles, une goupille interdit tout déboîtage de l'ensemble. It is for the sake of simplification and clarity of the presentation that two lengths of telescopic cranks have been chosen, the principle of length variation by a telescopic system allows, if necessary, a calibration of infinite lengths. The joysticks are placed on the main body of the cranks, a pin prevents any dislocation of the whole.
