Axe de blocage rapide d'une roue de bicyclette
L'invention concerne un axe de blocage rapide d'une roue de bicyclette. Quick-release axle of a bicycle wheel
The invention relates to a quick-release axle of a bicycle wheel.
L'invention concerne également un dispositif de mesure de la vitesse d'un cycle. The invention also relates to a device for measuring the speed of a cycle.
De façon connue, un axe de blocage rapide traverse le moyeu de la roue et se fixe à la fourche au moyen d'un levier que l'on fait pivoter dans une position de fermeture. Habituellement, dans cette position, le levier est rabattu dans un plan parallèle au plan général de la roue. In known manner, a quick locking pin passes through the hub of the wheel and is fixed to the fork by means of a lever which is pivoted in a closed position. Usually, in this position, the lever is folded in a plane parallel to the general plane of the wheel.
Un levier de ce type est par exemple décrit dans la demande de brevet EP 810 944. A lever of this type is for example described in patent application EP 810 944.
Une fois dans cette position, le levier n'est pas utilisé pour d'autres fonctions. Once in this position, the lever is not used for other functions.
L'invention propose un axe de blocage rapide amélioré. Une fois en position de fermeture le levier peut être utilisé pour une autre fonction qui, usuellement, est remplie par un autre élément rapporté sur la fourche. The invention proposes an improved rapid locking pin. Once in the closed position the lever can be used for another function which, usually, is fulfilled by another element attached to the fork.
A cet effet, l'invention propose un axe de blocage rapide comprenant une tige prévue pour traverser le moyeu de la roue, un bouchon mobile le long de la tige, dont le déplacement est commandé par un levier mobile entre une position d'ouverture, et une position de fermeture où il est situé dans un plan général perpendiculaire à l'axe défini par la tige. L'axe est caractérisé par le fait que le levier est un boîtier qui renferme un capteur prévu pour coopérer avec un élément accroché à l'un des rayons de la roue et pour détecter le passage dudit élément devant le boîtier, ainsi qu'un circuit de traitement et un émetteur prévus pour mettre en forme le signal issu du capteur, et émettre le signal résultant en direction d'un récepteur. To this end, the invention proposes a quick locking pin comprising a rod intended to pass through the wheel hub, a plug movable along the rod, the movement of which is controlled by a movable lever between an open position, and a closed position where it is located in a general plane perpendicular to the axis defined by the rod. The axis is characterized by the fact that the lever is a housing which encloses a sensor intended to cooperate with an element attached to one of the spokes of the wheel and to detect the passage of said element in front of the housing, as well as a circuit and a transmitter provided to format the signal from the sensor, and transmit the resulting signal to a receiver.
Le dispositif de mesure de la vitesse d'une bicyclette est prévu pour une bicyclette ayant un cadre, deux roues à rayons montées à l'aide d'un axe de blocage rapide ayant un levier mobile entre une position d'ouverture et une position de fermeture où le levier est rabattu dans un plan parallèle au plan général de la roue, une fourche avant, le dispositif comprenant un élément prévu pour être accroché à l'un des rayons de la roue, un capteur apte à détecter le passage de l'élément devant lui, un circuit de traitement et un émetteur prévus pour être accrochés à la fourche pour mettre en forme le signal issu du capteur, et émettre un signal en direction d'une unité centrale ayant un afficheur en vue du cycliste. Le dispositif est caractérisé par le fait que le capteur, le circuit de traitement, et l'émetteur sont placés dans un boîtier qui forme le levier de commande de l'axe de blocage rapide. The device for measuring the speed of a bicycle is provided for a bicycle having a frame, two spoked wheels mounted using a quick-release axle having a lever movable between an open position and a position of closure where the lever is folded in a plane parallel to the general plane of the wheel, a front fork, the device comprising an element intended to be attached to one of the spokes of the wheel, a sensor capable of detecting the passage of the element in front of it, a processing circuit and a transmitter provided to be hooked to the fork to shape the signal from the sensor, and send a signal towards a central unit having a display for the cyclist. The device is characterized in that the sensor, the processing circuit, and the transmitter are placed in a housing which forms the control lever of the quick-release axis.
L'invention sera mieux comprise en se référant à la description ci-dessous et aux dessins en annexe qui en font partie intégrante. The invention will be better understood by referring to the description below and to the accompanying drawings which form an integral part thereof.

<Desc/Clms Page number 2> <Desc / Clms Page number 2>
La figure 1 représente une bicyclette 1 qui, de façon connue comprend un cadre 2, deux roues avant et arrière 3 et 4, la roue avant 3 étant assemblée à l'extrémité d'une fourche 6 reliée par une potence 7 à un cintre de direction 8. FIG. 1 represents a bicycle 1 which, in known manner comprises a frame 2, two front and rear wheels 3 and 4, the front wheel 3 being assembled at the end of a fork 6 connected by a stem 7 to a hanger of direction 8.
La roue avant 3 est assemblée à la fourche au moyen d'un axe de blocage rapide 10 qui est manoeuvré par un levier 11. The front wheel 3 is assembled to the fork by means of a rapid locking pin 10 which is maneuvered by a lever 11.
L'axe est construit de façon traditionnelle, avec une tige longitudinale 12, un écrou 13 vissé à une extrémité, un bouchon mobile 14 guidé le long de la tige dont le déplacement est commandé par le levier de manoeuvre 11. Le levier de manoeuvre est mobile entre une position d'ouverture, où il est orienté sensiblement dans le prolongement de la tige et une position de fermeture où il est dans un plan perpendiculaire à la tige. Le mécanisme de commande est de tout type approprié. Par exemple il est réalisé conformément à la demande de brevet EP 810 944 citée en préambule. Selon ce mode de construction, le levier de manoeuvre est mobile autour d'un axe perpendiculaire à la direction de la tige, dans un plan contenant l'axe de la tige. Ceci n'est pas limitatif, et le levier de manoeuvre pourrait être décalé par rapport au plan contenant l'axe de la tige comme cela est décrit par exemple dans la demande de brevet FR 2 597 058. The axis is built in the traditional way, with a longitudinal rod 12, a nut 13 screwed at one end, a movable plug 14 guided along the rod whose movement is controlled by the operating lever 11. The operating lever is movable between an open position, where it is oriented substantially in the extension of the rod and a closed position where it is in a plane perpendicular to the rod. The control mechanism is of any suitable type. For example, it is produced in accordance with patent application EP 810 944 cited in the preamble. According to this construction method, the operating lever is movable about an axis perpendicular to the direction of the rod, in a plane containing the axis of the rod. This is not limiting, and the operating lever could be offset relative to the plane containing the axis of the rod as described for example in patent application FR 2 597 058.
La bicyclette est équipée d'un dispositif de mesure de vitesse. De façon connue, ce dispositif comprend une unité centrale avec un afficheur 15 qui est par exemple fixé à la potence de direction de façon à être visible pour le cycliste. The bicycle is equipped with a speed measuring device. In known manner, this device comprises a central unit with a display 15 which is for example fixed to the steering stem so as to be visible to the cyclist.
Il comprend par ailleurs un aimant 16 ou dispositif équivalent qui est accroché à l'un des rayons de la roue. Cet aimant est prévu pour coopérer avec un capteur, par exemple une ampoule relais de type Reed qui est chargée de détecter son passage. It also comprises a magnet 16 or equivalent device which is attached to one of the spokes of the wheel. This magnet is designed to cooperate with a sensor, for example a Reed type relay bulb which is responsible for detecting its passage.
Le dispositif de mesure de la vitesse est de type sans fil, c'est-à-dire qu'il comprend par ailleurs un émetteur associé au capteur qui émet en direction de l'unité centrale un signal en rapport avec la fréquence de passage de l'aimant devant le capteur. The speed measuring device is of the wireless type, that is to say it also comprises a transmitter associated with the sensor which transmits towards the central unit a signal related to the frequency of passage of the magnet in front of the sensor.
Selon l'invention, le levier 11 de l'axe de blocage 10 est un boîtier creux qui renferme le capteur 18. Le levier renferme non seulement le capteur, mais également une batterie d'alimentation 17, un circuit de traitement 19 chargé de mettre en forme le signal issu du capteur, un circuit émetteur 20 avec une antenne 21 chargé d'émettre un signal. Ce signal est émis en direction de l'antenne 22 située au niveau de l'unité centrale, elle-même reliée à un circuit de traitement 23 et un circuit d'affichage 24. According to the invention, the lever 11 of the locking pin 10 is a hollow housing which contains the sensor 18. The lever contains not only the sensor, but also a supply battery 17, a processing circuit 19 responsible for putting in form of the signal from the sensor, a transmitter circuit 20 with an antenna 21 responsible for transmitting a signal. This signal is transmitted towards the antenna 22 located at the level of the central unit, itself connected to a processing circuit 23 and a display circuit 24.
Le levier est réalisé en une matière non métallique, par exemple une matière plastique de façon à ne pas entraver la transmission électromagnétique. The lever is made of a non-metallic material, for example a plastic material so as not to impede the electromagnetic transmission.
Les signaux émis au niveau du levier 11 peuvent être de nature analogique conformément à ce qui est décrit par exemple dans le brevet US 5,008, 647. lis peuvent être également de type numérique codé. The signals transmitted at the level of the lever 11 can be of analog nature in accordance with what is described for example in US Pat. No. 5,008,647. They can also be of digital coded type.
La figure 2 représente en traits pointillés la batterie 17, le capteur 18 et le bobinage de l'antenne 21. De préférence, le capteur s'étend selon la direction longitudinale du levier et il est situé vers l'extrémité libre du levier, de façon à ce que lui et l'aimant soient le plus FIG. 2 shows in dotted lines the battery 17, the sensor 18 and the winding of the antenna 21. Preferably, the sensor extends in the longitudinal direction of the lever and it is located towards the free end of the lever, so that he and the magnet are the most

éloignés possible de l'axe de la roue. De préférence également, la batterie est une pile plate et ronde qui est située à l'extrémité libre du levier de façon à être accessible pour un remplacement éventuel. Par exemple, le levier a une forme générale cylindrique, et son extrémité libre présente un capot 25 que l'on peut visser ou dévisser à l'aide d'un outil pour accéder à la batterie. possible away from the wheel axle. Also preferably, the battery is a flat, round battery which is located at the free end of the lever so as to be accessible for possible replacement. For example, the lever has a generally cylindrical shape, and its free end has a cover 25 which can be screwed or unscrewed using a tool to access the battery.
Concernant l'antenne, on a trouvé que l'orientation longitudinale de la bobine le long du levier, et l'orientation horizontale vers l'arrière du levier qui est représentée en figure 1 assuraient dans de bonnes conditions la transmission des signaux entre le levier et l'unité centrale. Concerning the antenna, it has been found that the longitudinal orientation of the coil along the lever, and the horizontal orientation towards the rear of the lever which is represented in FIG. 1 ensured in good conditions the transmission of the signals between the lever and the central unit.
Naturellement la présente description n'est donnée qu'à titre indicatif, et l'on pourrait adopter d'autres modes de mise en oeuvre de l'invention sans pour autant sortir du cadre de celle-ci. Of course, this description is given for information only, and other modes of implementing the invention could be adopted without going beyond the scope of the latter.
En particulier, l'axe de blocage qui vient d'être décrit pourrait être placé à la roue arrière. In particular, the locking axle which has just been described could be placed at the rear wheel.
