Description

Manivelle d'entraînement fonctionnant sur le principe du levier L'invention comporte une bielle ou un levier destiné à entraîner un arbre qui formera dans ce dispositif la partie menée d'un couple dont la partie menante est le levier d'entraînement. Le dispositif de l'invention voit sa performance utile chaque fois que l'entraînement du levier est manuel à l'exemple d'une poignée pour entrainer une rotation quelconque ou plus concrètement le pédalier d'une bicyclette comportant deux manivelles ou bielles. 10 Dans ce cas précis, les manivelles d'entrainement du pédalier restent solidaires du plateau qui entraine la chaîne Toujours dans ce cas précis la force exercée sur la pédale de cet ensemble résulte de deux facteurs 15 Premier facteur la longueur de la biellette ou levier Deuxième facteur la pression exercée par le cycliste sur les pédales en vue de la rotation 20 La motricité humaine du cycle va résulter de la puissance du cycliste. Depuis des lustres on a installé une gamme de pignon sur la bicyclette ce qui permet de vaincre la résistance en choisissant le diamètre du pignon tracteur en fonction de la demande et des possibilités du cycliste. Tout cela existe au détriment de la vitesse. 25 2'972420 2 A son époque Archimède a inventé le principe du levier dont l'application débouche sur une puissance d'ou sa déclaration « donnez moi un point d'appui et je soulèverai le monde» fin de citation. The invention comprises a rod or a lever for driving a shaft which will form in this device the driven portion of a torque whose driving portion is the driving lever. The device of the invention sees its useful performance every time the drive lever is manual example of a handle to cause any rotation or more concretely the pedal of a bicycle with two cranks or connecting rods. 10 In this case, the pedal cranks remain attached to the chainring that drives the chain Always in this case the force exerted on the pedal of this set results from two factors 15 First factor the length of the link or lever Second factor the pressure exerted by the cyclist on the pedals for rotation The human motive of the cycle will result from the power of the cyclist. For ages we have installed a range of sprockets on the bicycle which overcomes the resistance by choosing the diameter of the tractor sprocket according to the demand and the possibilities of the cyclist. All this exists at the expense of speed. 25 2'972420 2 In his day Archimedes invented the principle of leverage, the application of which results in a power from which his statement "give me a fulcrum and I will raise the world" end of quote.

En clair, il a pris acte d'une force résistante ascensionnelle Clearly, he took note of a resilient upward force

Pour la maitriser ou la soulever, en somme pour la déplacer, il a utilisé un levier. To control or lift it, basically to move it, he used a lever.

Un peu à l'exemple de la manivelle d'un pédalier de bicyclette qui lorsque la pédale se trouve à trois heures des aiguilles d'une montre soulève la résistance opposée à neuf heures de cette montre Là existe un problème non résolu, non investi, non maitrisé aujourd'hui. Et solution 15 par la présente invention. Concrètement la résistance ascensionnelle situé à neuf heures du cadrant de la montre se trouve pratiquement à égale distance de la pression exercée sur le levier à trois heure de la montre. Bilan de ce qui précède et toujours dans le cas du Pédalier de bicyclette il suffira d'allonger un peu le levier d'entraînement du vélo qui passe par trois heures de la montre et se prolonge dans une distance limitée en raison de la garde au sol. 25 Toujours plus concrètement le pédalier de bicyclette doté du plateau porteur de chaîne, soit un ensemble formant la partie menée de la bicyclette par la transmission de la 20 2'972420 3 Chaine via les pignons de la roue tractrice, sont pris directement avec le pédaleur autrement dit la force exercée par le cycliste. Dans d'autre application manuelle, la présente invention souvent située dans la partie 5 menante d'une chaine cinématique de transmission comprenant la partie menante actionnée par une poignée ou une roue motrice rencontre la résistance formée par la partie menée. Si dans l'application de la bicyclette on a logé des pignons dentés dont l'augmentation 10 des diamètres permet de diminuer le couple résistant l'on peut appliquer également une réduction d'entrainement au niveau de la partie mené sous la forme d'une pignonerie. Pour être davantage précis au niveau de la partie menante dans un pédalier de bicyclettes l'on a installé un plateau dont le diamètre est inférieur en vue de diminuer le couple. La présente invention élimine tout application de cinématique de transmission formée par de la pignonerie des chaines ou courroies de transmission. A bit like the crank of a bicycle pedal that when the pedal is at three o'clock clock raises the resistance opposite nine hours of this watch There is an unresolved problem, not invested, not mastered today. And solution 15 by the present invention. In practical terms, the upward resistance at nine o'clock on the watch's dial is practically at equal distance from the pressure exerted on the lever at three o'clock in the watch. Review of the above and still in the case of the bicycle crankset it will be enough to extend a little the bike's training lever that goes through three hours of the watch and extends in a limited distance because of the ground clearance . All the more concretely, the bicycle crankset with the chain carrier plate, that is to say an assembly forming the driven part of the bicycle by the transmission of the chain via the pinions of the tractive wheel, are taken directly with the pedal. in other words, the force exerted by the cyclist. In another manual application, the present invention often located in the driving part of a transmission kinematic chain comprising the driving part actuated by a handle or a driving wheel meets the resistance formed by the driven part. If, in the application of the bicycle, toothed gears have been installed, the increase in diameters of which makes it possible to reduce the resistive torque, it is also possible to apply a reduction of drive at the part carried out in the form of a gear. gearing. To be more precise at the level of the driving part in a bicycle crankset has been installed a plate whose diameter is lower to reduce the torque. The present invention eliminates any application of transmission kinematics formed by gearing chains or transmission belts.

Fort de la puissance révélée par Archimède, la présente invention forme l'application d'un point d'appui située entre la partie menée : l'arbre porteur d'un plateau d'entrainement et l'extrémité de la bielle ou manivelle ou levier formé par un pédalier de bicyclette. Strong of the power revealed by Archimedes, the present invention forms the application of a fulcrum located between the driven part: the shaft carrying a drive plate and the end of the connecting rod or crank or lever formed by a bicycle crankset.

Plus concrètement l'application de l'invention adaptée sur une bicyclette formera le schéma de principe suivant. More concretely, the application of the adapted invention to a bicycle will form the following schematic diagram.

Premièrement : le plateau porteur de la chaine de transmission ou poulie comporte une roue folle qui s'articule sur l'axe du pédalier dans une bicyclette. Elle sera la partie menée Afin de l'entrainer pour former la partie menante les manivelles de pédaliers s'articulent sur le dispositif de rotation logé dans le châssis du vélo. Toujours dans cette application la roue folle ne comporte pas d'entrainement mais sous 10 l'effet de l'action exercée sur le pédalier ce dernier forme un moteur actionné par le cycliste ou entraine manuellement dans une autre application. L'invention implique de loger un axe dans le plateau d'entrainement qui forme la partie menante. Cet axe est avantageusement logé tout prés de l'arbre porteur de bielles ou de manivelles et relié à une manivelle du pédalier celle qui est solidaire de ce plateau. Il va en résulter que si l'on exerce une pression au niveau de la pédale d'une bicyclette First: the carrier plate of the chain of transmission or pulley comprises a crazy wheel which is articulated on the axis of the pedal in a bicycle. It will be the driven part In order to train it to form the driving part the pedal cranks are articulated on the rotation device housed in the chassis of the bike. Still in this application the idler wheel does not involve training but under the effect of the action exerted on the pedal it forms a motor operated by the cyclist or leads manually in another application. The invention involves housing an axis in the drive plate which forms the driving part. This axis is advantageously housed close to the shaft carrying connecting rods or cranks and connected to a crank of the pedal that is integral with this plate. It will result that if you exert pressure on the pedal of a bicycle

20 elle n'entrainera pas directement le plateau. En effet l'axe logé avantageusement prés de l'arbre porteur des manivelles lui va servir de point d'appui conformément au principe du levier d'Archimède. 25 Si l'on exerce une pression sur la pédale d'un vélo la manivelle porteuse de cette pédale prend appui sur l'axe qu'elle retient en provenance de la partie menée et par le moyen d'une rotation à l'autre extrémité du levier laquelle s'exerce au niveau de l'arbre porteur de la bielle. 15 2'972420 rJ Plus concrètement la manivelle du pédalier s'articule sur l'axe du pédalier et forme une extrémité du levier de l'invention Deuxièmement : l'axe de l'invention logé avantageusement prés de l'arbre d'entrainement relié à cette hauteur à la manivelle de pédalier forme le point d'appui dans l'application de ce principe du levier. L'extrémité de la manivelle qui retient une pédale standard forme le troisième point. 20 it will not train the board directly. Indeed, the axis housed advantageously close to the carrier shaft cranks it will serve as a fulcrum according to the principle of Archimedes lever. If one exerts pressure on the pedal of a bicycle, the pedal carrying this pedal bears on the axis which it holds from the driven part and by means of a rotation at the other end. the lever which is exerted at the level of the bearing shaft of the connecting rod. More concretely the crank of the pedal is articulated on the axis of the pedal and forms an end of the lever of the invention Secondly: the axis of the invention housed advantageously close to the drive shaft connected at this height the pedal crank forms the fulcrum in the application of this principle of the lever. The end of the crank that holds a standard pedal forms the third point.

Dans l'application de l'invention le principe du levier d'Archimède forme le diviseur du couple résistant entre la partie menée et la partie menante et prend la forme d'un convertisseur de couple. Le principe de l'invention a pour vocation de se substituer par l'augmentation de 15 puissance à la fatigue suite à l'effort fourni par un cycliste. En mécanique, un levier est une pièce rigide, allongée, généralement en liaison pivot ou en simple appui par rapport à une partie fixe, qui permet de transformer un mouvement. Le levier est l'une des huit machines simples. Le levier peut être utilisé de deux manières : pour amplifier un mouvement, en amplitude ou en vitesse ; l'une des premières applications fut sans doute l'atlatl ; *pour amplifier un effort.In the application of the invention the principle of the Archimedes lever forms the divider of the resisting torque between the driven part and the driving part and takes the form of a torque converter. The principle of the invention is intended to replace the increase in power to fatigue following the effort provided by a cyclist. In mechanics, a lever is a rigid piece, elongate, generally in pivot connection or in a simple support relative to a fixed part, which makes it possible to transform a movement. The lever is one of eight simple machines. The lever can be used in two ways: to amplify a movement, amplitude or speed; one of the first applications was undoubtedly atlatl; * to amplify an effort.

25 Les deux utilisations sont contradictoires : l'amplification du mouvement se fait aux dépens de l'effort, et l'amplification de l'effort se fait aux dépens de la vitesse et de l'amplitude du mouvement. 20 2972420 s Pour que le levier puisse jouer, il doit avoir un appui, appelé également hypomochlion ou hypomoclion (du grec IIO « sous » et µoXA'Oç « levier »). C'est aussi l'axe sur lequel on peut faire levier pour tourner. Ce terme est utilisé, notamment en odontostomatologie, pour désigner le centre de rotation, de la dent par rapport à son ancrage, 5 au niveau du desmodonte. Le bras levier est la distance séparant une extrémité du levier de son point d"appui. C'est aussi le rapport des deux bras, qui donne l'amplitude de l'effet de levier.The two uses are contradictory: the amplification of the movement is at the expense of the effort, and the amplification of the effort is at the expense of the speed and the amplitude of the movement. 20 2972420 s For the lever to play, it must have a support, also called hypomochlion or hypomoclion (Greek IIO "under" and μoXA'Oç "lever"). It is also the axis on which one can leverage to turn. This term is used, especially in odontostomatology, to designate the center of rotation of the tooth relative to its anchorage, 5 at the level of the periodontal. The lever arm is the distance between one end of the lever and the fulcrum, which is also the ratio of the two arms, which gives the amplitude of the leverage effect.

10 Dans une des applications de l'invention à titre indicatif et nontimitatif et à la figure 1, le repère (1) est le plateau d'une bicyclette porteur de chaînes partie menante de la motricité humaine fournie par la rotation des leviers (2) et (3). Ces Ieviers son t solidaires d'un arbre (4) qui s'articule dans le palier de la bicyclette. La manivelle ($) est solidaire de cet arbre, son extrémité (6) reçoit un axe (7) avantageusement logé dans le périmètre de l'arbre porteur de bielles sur cet arbre s'articule la partie menante (1). Toutes les fois que l'on appuie sur les extrémités (1) et (6) des bielles elles exercent une rotation de 360°. En appuyant au moyen d'une pédale sur la position (b) ou (6) selon la position de la rotation, la manivelle (3) entraine l'axe (7) avantageusement logé prés de l'arbre (4) afin d'entrainer la roue (1) au moyen de cet axe (7).In one of the applications of the invention as indicative and nontimitative and in Figure 1, the reference (1) is the plateau of a chain-carrying bicycle driving part of the human motility provided by the rotation of the levers (2). and (3). These levers are integral with a shaft (4) which is articulated in the bearing of the bicycle. The crank ($) is integral with this shaft, its end (6) receives an axis (7) advantageously housed in the perimeter of the rod-carrying shaft on this shaft articulates the driving portion (1). Whenever the ends (1) and (6) of the connecting rods are pressed, they exert a rotation of 360 °. By pressing with a pedal on the position (b) or (6) according to the position of the rotation, the crank (3) drives the axis (7) advantageously housed near the shaft (4) in order to driving the wheel (1) by means of this axis (7).

25 Si l'on se reporte au schéma (7) (4) et (a) on applique le principe du levier selon le principe d'Archiméde et l'on obtient une importante démultiplication du couple.20 A la figure 2 14 leviere (2) et s'articule sur une portée de roulement (8). La rotation de la poulie (1) se fait toujours sur le principe du levier. Referring to Fig. (7) (4) and (a) the principle of the lever is applied according to the Archimedean principle and a large reduction in the torque is obtained. 2) and is based on a rolling range (8). The rotation of the pulley (1) is always on the principle of the lever.
