La présente invention est relative à un dispositif de transmission pour cycles et analogues. The present invention relates to a transmission device for cycles and the like.
Dans le cas d'une bicyclette, la roue arrière est entraînée par un pédalier constitué par un grand plateau denté, ou plateau menant, dont la rotation est déterminée par des manivelles pourvues de pédales soumises à l'action de l'utilisateur, ledit plateau entraînant, par l'entremise d'une chaîne, un pignon claveté sur le moyeu de ladite roue par l'entremise d'un dispositif à roue libre (la roue n'étant entraînée que dans un sens). In the case of a bicycle, the rear wheel is driven by a pedal consisting of a large gear tray, or driving plate, whose rotation is determined by cranks provided with pedals subjected to the action of the user, said plate driving, via a chain, a pinion keyed to the hub of said wheel by means of a freewheel device (the wheel being driven in only one direction).
Le but de l'invention est de proposer un dispositif de transm ssion n'utilisant pas de chaîne de transmission. The object of the invention is to propose a transmission device that does not use a transmission chain.
Selon la présente invention, le plateau menant et le pignon mené sont montés sur l'arbre de la roue à entraîner, ledit plateau entraînant un pignon sur l'arbre duquel est claveté un second pignon entraînant le pignon usuel de la roue par l'entremise d'un ou de deux pignons satellites selon le sens de rotation dudit plateau. According to the present invention, the driving plate and the driven pinion are mounted on the shaft of the wheel to be driven, said plate driving a pinion on the shaft of which is keyed a second pinion driving the usual pinion of the wheel through one or two planet gears in the direction of rotation of said plate.
Le plateau est entraîné, avec interposition d'un dispositif à roue libre, par, au moins, un pignon en prise avec un secteur denté situé à l'extrémité d'un bras, articulé sur le cadre de l'engin et comportant un levier s'étendant au-delà de l'axe d'articulation sur l'extrémité duquel l'usager agit. The plate is driven, with the interposition of a freewheel device, by, at least, a pinion engaged with a toothed sector situated at the end of an arm, articulated on the frame of the machine and comprising a lever extending beyond the axis of articulation on the end of which the user acts.

-la figure 1 1 est une vue analogue à celle 4, montrant une variante de réalisation. FIG 1 1 is a view similar to that 4, showing an alternative embodiment.
En se reportant aux dessins et notamment aux figures 1 et 5, on voit que la roue 1 est montée de la façon usuelle sur un arbre 2 soutenu par une 25 fourche 3. Referring to the drawings and particularly to Figures 1 and 5, it is seen that the wheel 1 is mounted in the usual way on a shaft 2 supported by a fork 3.
Sur l'arbre 2 est monté un plateau denté 4 lié en rotation, par un dispositif à roue libre 5, à un pignon denté 6. On the shaft 2 is mounted a toothed plate 4 connected in rotation, by a freewheel device 5, to a toothed pinion 6.
Le pignon 6 est en prise avec un secteur denté 7 situé à l'une des extrémités d'un bras 8 articulé par son autre extrémité sur un arbre 9 1Dorté par le cadre 10 de l'engin. The pinion 6 is engaged with a sector gear 7 located at one end of an arm 8 hinged at its other end to a shaft 9 1Dorté by the frame 10 of the machine.
Le bras 8 s'étend au-delà de l'axe de l'arbre 9 en un levier 11 comportant une pédale 1 2, à son extrémité libre, sur laquelle l'utilisateur prend appui. Naturellement, des moyens sont prévus pour limiter la rotation du levier 1 1 et pour la faire pivoter en sens inverse en l'absence d'action sur la pédale, ceux-ci seront décrits plus loin. The arm 8 extends beyond the axis of the shaft 9 into a lever 11 having a pedal 1 2, at its free end, on which the user bears. Naturally, means are provided to limit the rotation of the lever 1 1 and to rotate it in the opposite direction in the absence of action on the pedal, these will be described later.
Lorsque le levier 11 pivote de sa position haute vers une position basse, le plateau 4 est entraîné par le pignon 6 à travers le dispositif à roue libre. Par contre, lorsque le levier 1 1 pivote en sens inverse, le dispositif à roue libre entre en action et le plateau n'est pas entraîné. When the lever 11 pivots from its high position to a low position, the plate 4 is driven by the pinion 6 through the freewheel device. By cons, when the lever 1 1 rotates in the opposite direction, the freewheel device comes into action and the tray is not driven.
La rotation du plateau 4 est transmise au pignon usuel 1 3 d'entraînement de la roue 1 par l'entremise d'un train de pignons 14-15-16-17. Le pignon 1 3 entraîne la roue 1 par l'entremise d'un dispositif à roue libre 18. The rotation of the plate 4 is transmitted to the usual pinion 1 3 driving the wheel 1 through a gear train 14-15-16-17. The pinion January 3 drives the wheel 1 by means of a freewheel device 18.
Les pignons 14 et 1 5 sont montés sur le même arbre et sont liés en rotation. Les pignons satellites 1 6 et 17 sont interposés entre ceux 1 3 et 1 5. The gears 14 and 1 5 are mounted on the same shaft and are connected in rotation. The planet gears 1 6 and 17 are interposed between those 1 3 and 1 5.
Comme cela ressort des dessins, on utilise deux secteurs dentés 7 et 7a, identiques et disposés de part et d'autre du plateau 4, le secteur 7a entraînant un pignon 6a par l'entremise d'un dispositif à roue libre 5a dont l'effet est inversé par rapport au dispositif à roue libre 5. De cette façon, le plateau 4 est entraîné dans le même sens, alternativement par le levier 1 1 et par celui 1 1 a. As can be seen from the drawings, two toothed sectors 7 and 7a are used, identical and arranged on either side of the plate 4, the sector 7a driving a pinion 6a by means of a freewheel device 5a of which effect is reversed with respect to the freewheel device 5. In this way, the plate 4 is driven in the same direction, alternately by the lever 1 1 and by that 1 1 a.
Les secteurs 7 et 7a sont à denture interne , comme cela ressort des figures 1 et 3, notamment, mais ils peuvent être à denture externe , ce qui permet de faire l'économie d'un pignon satellite, les pignons 1 5 et 1 6 étant remplacés par un pignon unique 1 9 (voir figures 2 et 4). The sectors 7 and 7a are internally toothing, as is apparent from Figures 1 and 3, in particular, but they can be external toothing, which makes it possible to economize a satellite pinion, the pinions 1 5 and 1 6 being replaced by a single pinion 1 9 (see Figures 2 and 4).
Le mode de réalisation de la figure 7 illustre la possibilité de réaliser un dispositif à plusieurs vitesses. The embodiment of FIG. 7 illustrates the possibility of producing a device with several speeds.
A cet effet, le dispositif à roue libre 1 8 comporte deux pignons 1:3a et 1 3b dont les diamètres sont différents. Le pignon 1 5 est en prise avec un pignon 1 6a, lié en rotation à un pignon 1 6b. Entre la paire 1 6a-1 6b, ou paire intermédiaire, et celle 1 3a-1 3b, est disposée une paire de pignons 17a-.17b, pouvant être déplacée axialement, la distance séparant les deux pignons d'une paire étant différente de celle séparant les pignons de l'autre paire. Par un déplacement judicieux de la paire mobile, ce qui est à la portée de l'homme de l'art, il est donc possible de relier soit les pignons 1 6a et 1 3a soit ceux 1 6b et 1 3b. A chaque tour du plateau 4, la roue 1 ne fera pas le même nombre de tours selon que le pignon 1 3a ou celui 1 3b est actif. For this purpose, the freewheel device 1 8 comprises two pinions 1: 3a and 1 3b whose diameters are different. The pinion 1 5 is engaged with a pinion 1 6a, rotatably connected to a pinion 1 6b. Between the pair 1 6a-1 6b, or intermediate pair, and that 1 3a-1 3b, is disposed a pair of pinions 17a-17b, can be moved axially, the distance between the two gears of a pair being different from the one separating the gears of the other pair. By a judicious movement of the moving pair, which is within the reach of those skilled in the art, it is therefore possible to connect either the gears 1 6a and 1 3a or those 1 6b and 1 3b. At each turn of the plate 4, the wheel 1 will not do the same number of turns depending on whether the pinion 1 3a or 1 3b is active.
Pour propulser l'engin, l'utilisateur appuie alternativement sur la pédale 1 2 ou sur celle 1 2a et l'on peut concevoir qu'un ressort de rappel ramène la pédale non actionnée en position haute pendant que l'autre descend. To propel the machine, the user alternately press the pedal 1 2 or 1 2a and it is conceivable that a return spring brings the non-actuated pedal up while the other goes down.
Le dispositif représenté sur les figures 8 et 9 permet d'atteindre un 25 résultat analogue. The device shown in Figures 8 and 9 achieves a similar result.
Chaque bras denté se raccorde au levier correspondant par l'entremise d'un moyeu respectivement 20 et 20a, disposé de part et d'autre de la partie inférieure 21 du cadre 1 0 de l'engin. Each toothed arm connects to the corresponding lever through a hub respectively 20 and 20a, disposed on either side of the lower part 21 of the frame 1 0 of the machine.
La face interne de chaque moyeu présente une dentelure 22 et 22a en prise avec un pignon conique 23 centré sur l'axe de l'arbre 9 et porté par la partie 21. Lorsque l'un des leviers pivote, il entraîne le pignon 23 qui fait pivoter l'autre levier en sens inverse. The inner face of each hub has a serration 22 and 22a engaged with a conical gear 23 centered on the axis of the shaft 9 and carried by the part 21. When one of the levers pivots, it drives the pinion 23 which rotate the other lever in the opposite direction.
Sur la figure 9 et pour plus de clarté, le moyeu 20 a été enlevé et la partie 21 est supposée transparente. In Figure 9 and for clarity, the hub 20 has been removed and the portion 21 is assumed to be transparent.
Afin que chaque secteur denté reste en prise avec son pignon correspondant, il est nécessaire de limiter la rotation des leviers 1 1 et 1 1 a. A cet effet et selon un mode de réalisation, chaque moyeu présente une lumière circulaire 24 centrée sur l'axe de l'arbre 9 dans laquelle s'étend un doigt formé, par exemple, par l'extrémité d'un arbre fixe 25 porté par la partie 21. So that each toothed sector remains in engagement with its corresponding gear, it is necessary to limit the rotation of the levers 1 1 and 1 1 a. For this purpose and according to one embodiment, each hub has a circular slot 24 centered on the axis of the shaft 9 in which extends a finger formed, for example, by the end of a fixed shaft 25 carried. by part 21.
De la description ci-dessus, il ressort que le dispositif de l'invention est déporté par rapport au plan de la roue, ce qui peut créer un déséquilibre et implique de couder les bras et les leviers pour que les deux pédales soient disposées de part et d'autre du plan vertical médian de l'engin. From the above description, it appears that the device of the invention is offset with respect to the plane of the wheel, which can create an imbalance and involves bending the arms and levers so that the two pedals are arranged from and other of the vertical vertical plane of the machine.
Pour remédier à cet inconvénient, il est prévu d'utiliser deux plateaux, chacun de ceux-ci et l'ensemble des pignons permettant de transmettre le mouvement à la roue étant disposés de part et d'autre du plan de ladite roue, chaque plateau étant associé à une roue libre unique. La roue libre affectée à un plateau étant inversée par rapport à celle affectée à l'autre plateau. To remedy this drawback, it is intended to use two trays, each of these and all the pinions for transmitting the movement to the wheel being disposed on either side of the plane of said wheel, each tray being associated with a single free wheel. The free wheel assigned to a plate being inverted with respect to that assigned to the other plate.
Ce mode de réalisation est particulièrement intéressant lorsque le dispositif de l'invention doit être utilisé sur un engin tel qu'un tricycle comportant deux roues sur le même axe. This embodiment is particularly advantageous when the device of the invention is to be used on a machine such as a tricycle having two wheels on the same axis.
2878498 6 Il en est de même lorsque le dispositif de l'invention est utilisé sur un fauteuil roulant comme montré sur la figure 10. Dans ce cas, la propulsion peut être obtenu soit en poussant, soit en tirant, sur les leviers 26. It is the same when the device of the invention is used on a wheelchair as shown in Figure 10. In this case, the propulsion can be obtained by pushing or pulling on the levers 26.
Dans ce cas, il est à noter que l'extrémité libre de chaque levier peut comporter la poignée de commande d'un dispositif de freinage analogue à ceux utilisés sur les bicyclettes, l'utilisation de l'un des freins, combinée avec l'actionnement de l'autre levier, permettant de faire virer le fauteuil. In this case, it should be noted that the free end of each lever may comprise the control handle of a braking device similar to those used on bicycles, the use of one of the brakes, combined with the actuation of the other lever, allowing to turn the chair.
Comme cela ressort de la figure Il, le dispositif de l'invention se prête bien à une motorisation, notamment, pour assister l'utilisateur. As is apparent from Figure 11, the device of the invention lends itself well to a motor, in particular to assist the user.
A cet effet, on utilise un moteur 27, de préférence électrique, comportant une bielle 28 reliée, par l'entremise d'une biellette 29, au levier 15 11. Un dispositif analogue, repéré 28a-29a, peut être appliqué au levier 1 1 a. For this purpose, a motor 27, preferably electric, is used which comprises a connecting rod 28 connected, via a link 29, to the lever 11. A similar device, marked 28a-29a, can be applied to the lever 1 1 a.
