Description

Dispositif antivol - blocage rapide de roue de bicyclette Antitheft device - quick release of bicycle wheel
La présente invention concerne les dispositifs antivol de roue de bicyclette et plus particulièrement les bicyclettes dont les roues sont bloquées sur la fourche avant ou sur le hauban arrière par un système de blocage rapide du type manette - excentrique - rondelle d'appui - vis - écrou. La manette étant solidaire de l'excentrique, l'excentrique étant en appui et lié en rotation à la rondelle d'appui et la vis traversant de part en part l'axe de la roue de bicyclette.The present invention relates to anti-theft devices for bicycle wheels and more particularly to bicycles whose wheels are locked on the front fork or on the rear stay by means of a quick release system of the joystick-eccentric type - thrust washer - screw - nut . The lever being secured to the eccentric, the eccentric bearing and rotatably connected to the bearing washer and the screw passing through the axis of the bicycle wheel.
Pour protéger contre Ie vol les éléments constitutifs d'une bicyclette et en particulier les éléments équipés de moyens à montage et démontage rapides, comme précisément les roues, il existe en fait peu de solutions. Ces solutions quand elles existent sont souvent d'un poids élevé, compliquées, onéreuses, très rarement intégrées à la bicyclette et nécessitent très souvent l'utilisation d'une clef de manœuvre.To protect against theft components of a bicycle and in particular the elements equipped with means for quick assembly and disassembly, such as wheels, there are in fact few solutions. These solutions when they exist are often of a high weight, complicated, expensive, very rarely integrated into the bicycle and very often require the use of a key maneuver.
Le dispositif selon l'invention permet de remédier à ces inconvénients, il est en effet léger et particulièrement simple, d'un prix de revient bas et de plus il ne remet pas en cause les éléments constitutifs de la bicyclette, au contraire, il les utilise. Autre intérêt de ce nouveau dispositif, il est particulièrement discret et ne change pratiquement pas l'apparence de Ia bicyclette. Si toutefois le dispositif de l'invention n'a pas besoin de clef c'est qu'il utilise dans sa mise en œuvre le retournement de la bicyclette. En effet, le dispositif antivol de l'invention est actif lorsque la bicyclette est dans une position normale à savoir reposant sur ses roues et inactif lorsque la bicyclette est dans une position retournée à savoir reposant par exemple sur la selle et le guidon.The device according to the invention overcomes these disadvantages, it is indeed light and particularly simple, a low cost and moreover it does not question the constituent elements of the bicycle, on the contrary, it uses. Another advantage of this new device, it is particularly discreet and does not change the appearance of the bicycle. However, if the device of the invention does not need a key is that it uses in its implementation the turning of the bicycle. Indeed, the antitheft device of the invention is active when the bicycle is in a normal position to know resting on its wheels and inactive when the bicycle is in a returned position namely resting for example on the saddle and the handlebars.
Le vol de roue de bicyclette intervenant généralement lorsque la bicyclette est déjà attachée à un point fixe par un cadenas la rendant alors pratiquement impossible à retourner, on dispose donc avec le dispositif de l'invention d'un dispositif antivol de roues basé sur le retournement de la bicyclette.The bicycle wheel theft usually occurring when the bicycle is already attached to a fixed point by a padlock making it virtually impossible to return, it is therefore with the device of the invention a wheel lock device based on the reversal of the bicycle.
Le dispositif antivol selon l'invention modifie et équipe le système de blocage rapide à manette - excentrique - rondelle d'appui - vis - écrou de la roue de bicyclette. Ce dispositif antivol et Ie système de blocage rapide constituant un nouveau dispositif appelé dispositif antivol - blocage rapide mettant en œuvre selon une première caractéristique plusieurs aménagements et moyens qui se combinent et coopèrent entre eux. Un premier moyen permet de serrer l'écrou lors de la manœuvre de mise en place et de serrage du dispositif antivol - blocage rapide, par contre ce premier moyen est conçu pour interdire et ne pas permettre le desserrage de l'écrou, une fois Ie dispositif antivol - blocage rapide serré. Ensuite, la rondelle d'appui de l'excentrique est pourvue d'une butée anti- rotation qui vient prendre place entre les deux pattes d'un bras de la fourche de façon à ce que l'axe d'articulation de l'excentrique et son pivot soient tous les deux sur une verticale terrestre, lorsque précisément la bicyclette se trouve dans une position normale. La tête de la vis, quant à elle, est rendue solidaire du pivot. Enfin, l'invention utilise un moyen de blocage en rotation de l'excentrique par rapport à son pivot, ce moyen de blocage mettant en œuvre un élément mobile guidé. Cet élément mobile qui est donc guidé peut être déplacé dans deux positions de travail différentes sous l'action conjuguée de son propre poids et d'une rotation sur lui-même et de 180° du moyen de blocage. Cette rotation du moyen de blocage s'obtient lorsque la bicyclette passe d'une position normale à une position retournée et inversement.The antitheft device according to the invention modifies and equips the quick release system with handle - eccentric - support washer - screw - nut of the bicycle wheel. This anti-theft device and the quick release system constituting a new device called anti-theft device - quick release implementing according to a first feature several arrangements and means that combine and cooperate with each other. A first means makes it possible to tighten the nut during the operation of setting However, this first means is designed to prevent and not allow the loosening of the nut, once the anti-theft device - fast blocking tight. Then, the support washer of the eccentric is provided with an anti-rotation stop which takes place between the two legs of an arm of the fork so that the axis of articulation of the eccentric and its pivot are both on a terrestrial vertical, when precisely the bicycle is in a normal position. The head of the screw, meanwhile, is secured to the pivot. Finally, the invention uses a locking means in rotation of the eccentric with respect to its pivot, this locking means implementing a guided mobile element. This movable element which is thus guided can be moved in two different working positions under the combined action of its own weight and a rotation on itself and 180 ° of the locking means. This rotation of the locking means is obtained when the bicycle moves from a normal position to an inverted position and vice versa.
L'élément mobile prend une première position de travail, lorsque la bicyclette est dans une position retournée, première position de travail qui permet à l'excentrique de tourner librement autour du pivot. L'élément mobile prend une deuxième position de travail, lorsque la bicyclette est dans une position normale et que le dispositif antivol - blocage rapide est en position serrée, deuxième position de travail dans laquelle l'élément mobile bloque et interdit à l'excentrique de tourner autour du pivot.The movable member takes a first working position, when the bicycle is in an upturned position, first working position that allows the eccentric to rotate freely around the pivot. The movable element takes a second working position, when the bicycle is in a normal position and the antitheft device - quick release is in a tight position, second working position in which the movable element blocks and prohibits the eccentric of turn around the pivot.
Afin de protéger l'élément mobile des agressions extérieures du type poussière, boue, et eau, le moyen de blocage est pourvu d'un moyen d'étanchéité.In order to protect the mobile element from external aggression of the dust, mud and water type, the blocking means is provided with a sealing means.
Selon un mode particulier de réalisation du moyen qui interdit le desserrage de l'écrou, on modifie ce dernier afin qu'il présente une géométrie extérieure en forme de dôme aplati ayant une surface parfaitement lisse et parfaitement dure. Ainsi lorsque le dispositif antivol - blocage rapide est serré il devient impossible de saisir et de desserrer l'écrou que ce soit manuellement ou avec un outil à main.According to a particular embodiment of the means which prohibits the loosening of the nut, the latter is modified so that it has a flattened dome-shaped outer geometry having a perfectly smooth and perfectly hard surface. Thus when the anti-theft device - quick release is tight it becomes impossible to grasp and loosen the nut either manually or with a hand tool.
Selon un autre mode particulier concernant toujours Pécrou, celui-ci est équipé d'un bouton de manœuvre collé à la surface du dôme et donc solidaire de ce dernier. Ce bouton ne pouvant transmettre à l'écrou qu'un couple de serrage ou de desserrage d'une valeur maximale de 0,2 mN, et se décollant du dôme si le couple dépasse 0,2 mN. Le bouton reste donc solidaire et opérationnel tant qu'il n'est pas soumis à un couple de 0,2 mN. Cette valeur de 0,2 mN correspondant au couple maximum qu'une main peut généralement transmettre à un tel bouton. Ainsi il est possible de pouvoir manuellement visser et approcher l'écrou sur les pattes du bras de fourche lors de la manœuvre de mise en place et de serrage du dispositif antivol - blocage rapide, il est par contre impossible de desserrer l'écrou, une fois le dispositif antivol - blocage rapide en place, sans risquer de désolidariser le bouton de l'écrou. Selon un premier mode particulier de réalisation le moyen de blocage est constitué d'une goupille, d'une tête cylindrique prolongeant le pivot et d'un bossage cylindrique prolongeant l'excentrique. La goupille cylindrique constitue l'élément mobile du moyen de blocage. La tête cylindrique qui prolonge le pivot est pourvue d'un perçage cylindrique, qui accueille la goupille, ce perçage ne débouche pas et présente une profondeur supérieure à la longueur de la goupille. Le bossage cylindrique qui prolonge l'excentrique est pourvu d'un perçage cylindrique également non débouchant, ce perçage pouvant accueillir partiellement la goupille. Lorsque le dispositif antivol - blocage rapide est en position serrée les deux perçages se retrouvent par conception opposés et concentriques. Ce premier moyen de blocage est protégé par un moyen d'étanchéité qui est constitué de deux joints, l'un situé entre le pivot et l'excentrique et l'autre situé entre la tête et le bossage.According to another particular mode still nécrou, it is equipped with an operating button glued to the surface of the dome and therefore secured to the latter. This button can transmit to the nut only a tightening torque or loosening of a maximum value of 0.2 mN, and detaching from the dome if the torque exceeds 0.2 mN. The button remains solidary and operational as long as it is not subjected to a torque of 0.2 mN. This value of 0.2 mN corresponding to the maximum torque that a hand can generally transmit to such a button. Thus it is possible to manually screw and approach the nut on the tabs of the fork arm during the maneuver installation and tightening of the anti-theft device - quick release, it is against impossible to loosen the nut, a anti-theft device - fast lock in place, without the risk of disconnecting the nut button. According to a first particular embodiment of the locking means consists of a pin, a cylindrical head extending the pivot and a cylindrical boss extending the eccentric. The cylindrical pin constitutes the movable element of the locking means. The cylindrical head which extends the pivot is provided with a cylindrical bore which receives the pin, this bore does not open and has a depth greater than the length of the pin. The cylindrical boss that extends the eccentric is provided with a cylindrical bore also non-opening, this bore partially accommodating the pin. When the antitheft device - quick release is in tight position the two holes are found by opposing and concentric design. This first blocking means is protected by a sealing means which consists of two seals, one located between the pivot and the eccentric and the other located between the head and the boss.
Lorsque la bicyclette est dans une position retournée, la goupille prend place entièrement dans le perçage de la tête cylindrique. Lorsque la bicyclette est dans une position normale et le dispositif antivol - blocage rapide en position serrée, la goupille prend place simultanément dans les deux perçages, et entraîne alors le blocage mécanique de la tête par rapport au bossage.When the bicycle is in an upturned position, the pin fully sits in the bore of the cylindrical head. When the bicycle is in a normal position and the antitheft device - quick release in the tight position, the pin takes place simultaneously in the two holes, and then causes the mechanical locking of the head relative to the boss.
Selon une variante de ce premier mode de réalisation du moyen de blocage, celui-ci met en œuvre non pas une seule mais quatre goupilles avec ses perçages associés. Les quatre ensembles goupille - perçages sont positionnés sur les quatre arêtes d'une pyramide de sorte à former une pyramide centrée sur l'axe de la tête et du bossage. L'angle de la pyramide ayant une valeur choisie entre 45 et 90 °. On dispose avec cette dernière variante d'une solution obligeant à retourner la bicyclette dans une position parfaitement verticale pour permettre le déblocage du dispositif antivol - blocage rapide. Selon un deuxième mode particulier de réalisation, le moyen de blocage est constitué d'une clavette de section carrée, d'un tourillon cylindrique prolongeant le pivot et d'un boîtier cylindrique prolongeant l'excentrique. La clavette de section carrée constitue l'élément mobile du moyen de blocage. Le tourillon qui prolonge le pivot présente à la fois une rainure de section carrée et un dégagement cylindrique. Le boîtier cylindrique prolongeant l'excentrique est naturellement solidaire à ce dernier. Ce boîtier est fermé et accueille le tourillon, il est par ailleurs pourvu d'une rainure de section carrée. La clavette prend place et peut coulisser librement dans la rainure du boîtier. Ce deuxième moyen de blocage est également protégé par un moyen d'étanchéité constitué d'un joint qui prend place entre le pivot et l'excentrique. Lorsque la bicyclette est dans une position retournée, la clavette prend place simultanément dans le fond de la rainure du boîtier et dans le dégagement du tourillon.According to a variant of this first embodiment of the locking means, it implements not one but four pins with its associated holes. The four pin-hole sets are positioned on the four edges of a pyramid so as to form a pyramid centered on the axis of the head and boss. The angle of the pyramid having a value chosen between 45 and 90 °. With this latter variant, there is a solution requiring the bicycle to be returned to a perfectly vertical position to enable unlocking of the antitheft device - quick release. According to a second particular embodiment, the locking means consists of a square section key, a cylindrical pin extending the pivot and a cylindrical housing extending the eccentric. The square section key is the movable element of the locking means. The journal that extends the pivot has both a square section groove and a cylindrical clearance. The cylindrical housing extending the eccentric is naturally attached to the latter. This housing is closed and accommodates the trunnion, it is also provided with a groove of square section. The key takes place and can slide freely in the groove of the housing. This second locking means is also protected by a sealing means consisting of a seal which takes place between the pivot and the eccentric. When the bicycle is in an inverted position, the key takes place simultaneously in the bottom of the groove of the housing and in the release of the trunnion.
Lorsque la bicyclette est dans une position normale et le dispositif antivol - blocage rapide est en position serrée, ia clavette prend place simultanément dans la rainure du boîtier et la rainure du tourillon et entraîne alors le blocage du boîtier par rapport au tourillon.When the bicycle is in a normal position and the antitheft device - quick release is in the tight position, the key takes place simultaneously in the groove of the housing and the groove of the trunnion and then causes the locking of the housing relative to the trunnion.
Selon un troisième mode particulier de réalisation, le moyen de blocage est constitué d'un embout de section carrée prolongeant le pivot, de deux rondelles crénelées et d'un boîtier cylindrique. La première rondelle crénelée constitue l'élément mobile. Cette première rondelle percée d'un trou de section carrée est engagée sur l'embout de section carrée sur lequel elle peut coulisser sans pouvoir tourner. La deuxième rondelle crénelée également percée est également engagée sur l'embout carré. Cette dernière rondelle est solidaire de l'excentrique et laisse le pivot et son embout carré libres en rotation. Le boîtier cylindrique en prolongement de l'excentrique est solidaire à ce dernier. Ce boîtier fermé recouvre sans les toucher l'embout carré et la rondelle crénelée mobile. Ce troisième moyen de blocage est également protégé par un moyen d'étanchéité constitué d'un joint qui prend place entre le pivot et l'excentrique. Lorsque la bicyclette est dans une position retournée, la rondelle crénelée mobile prend place contre le fond du boîtier et n'est pas au contact de la rondelle crénelée solidaire de l'excentrique. Lorsque la bicyclette est dans une position normale et le dispositif antivol - blocage rapide est en position serrée, la rondelle crénelée mobile vient s'engager et se bloquer en rotation sur la rondelle crénelée solidaire de l'excentrique.According to a third particular embodiment, the locking means consists of a square section tip extending the pivot, two serrated washers and a cylindrical housing. The first crenellated washer is the movable element. This first washer pierced with a hole of square section is engaged on the tip of square section on which it can slide without being able to turn. The second serrated ring also pierced is also engaged on the square end. This last washer is integral with the eccentric and leaves the pivot and its square end free to rotate. The cylindrical housing in extension of the eccentric is integral with the latter. This closed box covers without touching the square end and the crenellated mobile washer. This third locking means is also protected by a sealing means consisting of a seal which takes place between the pivot and the eccentric. When the bicycle is in an upturned position, the mobile crenellated washer is placed against the bottom of the housing and is not in contact with the crenellated washer secured to the eccentric. When the bicycle is in a normal position and the antitheft device - quick release is in a tight position, the mobile castellated washer engages and locks in rotation on the crenellated washer integral with the eccentric.
Selon un quatrième mode particulier de réalisation, le moyen de blocage est constitué d'une chape prolongeant le pivot, d'un cliquet articulé, d'un boîtier prolongeant l'excentrique. La chape qui prolonge le pivot est pourvue d'un axe d'articulation. Le cliquet articulé constitue l'élément mobile, le cliquet prend place dans la chape et s'articule autour de l'axe d'articulation de cette dernière. Le boîtier cylindrique qui prolonge l'excentrique et qui lui est solidaire est pourvu d'une rainure pouvant accueillir l'extrémité du cliquet. Ce quatrième moyen de blocage est également protégé par un moyen d'étanchéité constitué d'un joint qui prend place entre le pivot et l'excentrique.According to a fourth particular embodiment, the locking means consists of a yoke extending the pivot, an articulated pawl, a housing extending the eccentric. The yoke which extends the pivot is provided with a hinge pin. The hinged pawl is the movable element, the pawl takes place in the yoke and is articulated around the axis of articulation of the latter. The cylindrical housing which extends the eccentric and which is secured to it is provided with a groove that can accommodate the end of the pawl. This fourth locking means is also protected by a sealing means consisting of a seal which takes place between the pivot and the eccentric.
Lorsque la bicyclette est dans une position retournée, le cliquet prend place dans le fond du boîtier et n'est pas au contact de la rainure.When the bicycle is in an inverted position, the pawl takes place in the bottom of the housing and is not in contact with the groove.
Lorsque la bicyclette est dans une position normale et le dispositif antivol - blocage rapide est dans la position serrée, le cliquet vient s'engager et se bloquer dans la rainure du boîtier.When the bicycle is in a normal position and the antitheft device - quick release is in the tightened position, the pawl engages and locks in the groove of the housing.
Selon une variante, l'élément mobile est constitué d'un matériau amagnétique de façon à ne pas pouvoir être déplacé au moyen d'un aimant ou d'un électroaimant depuis l'extérieur du dispositif anti-vol - blocage rapide. Selon une autre variante, le moyen de blocage de la rotation de l'excentrique par rapport au pivot est étanche et rempli d'un fluide visqueux d'une viscosité choisie dans lequel baigne et évolue l'élément mobile. Le fluide visqueux freinant et ralentissant les mouvements de l'élément mobile il s'ensuit d'une part que le dispositif anti-vol ne peut être neutralisé par des secousses et d'autre part que la désactivation du dispositif antivol - blocage rapide se fait avec un certain retard, retard qui permet de temporiser l'ouverture du dispositif anti-vol - blocage rapide.Alternatively, the movable member is made of a non-magnetic material so that it can not be moved by means of a magnet or an electromagnet from outside the anti-theft device - fast blocking. According to another variant, the means for blocking the rotation of the eccentric with respect to the pivot is sealed and filled with a viscous fluid of a chosen viscosity in which bathes and evolves the movable element. The viscous fluid braking and slowing the movements of the movable element it follows on the one hand that the anti-theft device can not be neutralized by jolts and secondly that the deactivation of the anti-theft device - fast blocking is done with a certain delay, delay which delays the opening of the anti-theft device - fast blocking.

En référence à ces dessins, l'écrou (55) présentant la particularité d'être d'une part vissable lors de la manœuvre de mise en place et de serrage du dispositif antivol - blocage rapide (1) de l'invention, et d'être d'autre part impossible à desserrer une fois le dispositif antivol - blocage rapide (1) en place et serré est obtenu suivant plusieurs solutions. Une première solution consiste à donner à l'écrou (55) une géométrie extérieure en forme de dôme (56) aplatie présentant une surface (57) parfaitement lisse et parfaitement dure. Une deuxième solution variante de la précédente consiste à coller un bouton de manœuvre à la surface (57) du dôme (56) de l'écrou (55). Le collage du bouton sur la surface (57) du dôme (56) étant calculé afin que ledit bouton ne puisse transmettre à l'écrou (55) qu'un couple de serrage ou de desserrage d'une valeur maximale de 0,2 mN. Dans cette solution, le bouton se décolle et se désolidarise du dôme (56) de l'écrou (55) dès que le couple transmis au bouton dépasse les 0,2 mN.With reference to these drawings, the nut (55) having the particularity of being firstly screwable during the maneuvering establishment and tightening of the antitheft device - quick release (1) of the invention, and on the other hand, it is impossible to loosen once the anti-theft device - quick release (1) in place and tightened is obtained according to several solutions. A first solution is to give the nut (55) a flattened dome-shaped outer geometry (56) having a perfectly smooth and perfectly hard surface (57). A second variant of the previous solution is to stick an operating knob to the surface (57) of the dome (56) of the nut (55). The gluing of the button on the surface (57) of the dome (56) is calculated so that said button can transmit to the nut (55) a tightening or loosening torque of a maximum value of 0.2 mN . In this solution, the button comes off and disengages from the dome (56) of the nut (55) as soon as the torque transmitted to the button exceeds 0.2 mN.
Une troisième solution également variante de (a première solution consiste à coller un bouton de manœuvre « mou » à la surface (57) du dôme (56). Ce bouton « mou », comme le bouton collé, facilite l'approche de l'écrou (55) sur les pattes (4) du bras (3) de fourche (2) lors de la manœuvre de mise en place et serrage du dispositif antivol - blocage rapide (1) mais ne permet pas, ni même avec un outil, de desserrer l'écrou (55) une fois le dispositif antivol - blocage rapide (1) en place et serré.A third solution also variant of (a first solution is to stick a "soft" maneuver button on the surface (57) of the dome (56) .This button "soft", like the button glued, facilitates the approach of the nut (55) on the legs (4) of the arm (3) fork (2) during the maneuver of setting up and tightening the anti-theft device - quick release (1) but does not allow, or even with a tool, loosen the nut (55) once the anti - theft - quick release device (1) is in place and tightened.
Selon l'invention, la rondelle d'appui (36) est pourvue d'une butée (37) antirotation venant prendre place entre les deux pattes (4) d'un bras (3) de fourche (2). Ainsi la rondelle d'appui (36) occupe toujours la même position par rapport à la fourche (2) et par conséquence par rapport à la bicyclette. Comme l'excentrique (8) est lié en rotation à la rondelle d'appui (36) suivant l'axe (40), il occupe également toujours la même position par rapport à la fourche (2) et par conséquence par rapport à la bicyclette. La liaison en rotation de l'excentrique (8) par rapport à la rondelle d'appui (36) est assurée par la piste semi-circulaire (39) partie intégrante de la rondelle d'appui (36) sur laquelle vient s'appuyer l'excentrique (8). L'excentrique (8) restant par ailleurs toujours libre de sa rotation autour de l'axe (9). La butée (37) est positionnée sur Ia rondelle d'appui (36) de façon à ce que l'axe (9) d'articulation de l'excentrique (8) et de son pivot (23) soient sur une verticale terrestre lorsque la bicyclette est dans une position normale, à savoir reposant sur ses roues et sur un sol horizontal. La butée (37) peut selon l'invention être obtenue de différentes façons : - elle peut faire partie intégrante de la rondelle d'appui (36) et être réalisée au moment de l'usinage de cette dernièreAccording to the invention, the bearing washer (36) is provided with a stop (37) antirotation taking place between the two lugs (4) of an arm (3) fork (2). Thus the bearing washer (36) always occupies the same position relative to the fork (2) and consequently with respect to the bicycle. As the eccentric (8) is rotatably connected to the bearing washer (36) along the axis (40), it also always occupies the same position with respect to the fork (2) and consequently with respect to the bicycle. The rotational connection of the eccentric (8) with respect to the bearing washer (36) is provided by the semicircular track (39) integral with the bearing washer (36) on which is supported the eccentric (8). The eccentric (8) still remains free of its rotation about the axis (9). The stop (37) is positioned on the support washer (36) so that the axis (9) of articulation of the eccentric (8) and its pivot (23) are on a terrestrial vertical when the bicycle is in a normal position, namely resting on its wheels and on a horizontal ground. The abutment (37) can according to the invention be obtained in different ways: - It can be an integral part of the bearing washer (36) and be performed at the time of machining thereof
- elle peut être rapportée sur la périphérie de la rondelle d'appui (36) par vissage par collage ou encore par soudure, - elle peut être également ajustable et se présenter sous la forme d'un pion que l'on vient introduire et bloquer dans un des trous aménagés en périphérie de la rondelle d'appui (36), dernière variante qui permet quelque soit la position relative des pattes (4) par rapport au bras (3) de fourche (2) de garantir la verticalité de l'axe (9). Selon l'invention la tête (51) de vis (50) est solidaire du pivot (23), cette solidarisation pouvant être obtenue de différentes façons :- It can be attached to the periphery of the bearing washer (36) by screwing by gluing or by welding, - it can also be adjustable and be in the form of a pin that is just introduced and blocked in one of the holes arranged on the periphery of the bearing washer (36), the last variant which allows whatever the relative position of the tabs (4) with respect to the arm (3) of the fork (2) to guarantee the verticality of the axis (9). According to the invention the head (51) of screw (50) is integral with the pivot (23), this joining can be obtained in different ways:
- le pivot (23) peut être engagé et bloqué en force dans la tête (51) de vis (50) ainsi qu'il apparaît sur les figures 4, 14 et 16,- the pivot (23) can be engaged and blocked in force in the head (51) of screws (50) as it appears in Figures 4, 14 and 16,
- le pivot (23) peut être vissé et collé dans la tête (51) de vis (50), - le pivot (23) peut également être soudé à la tête (51) de vis (50),- the pivot (23) can be screwed and glued into the head (51) of screws (50), - the pivot (23) can also be welded to the head (51) of screws (50),
- le pivot (23), en référence à la figure 10, peut également si sa taille lui permet recevoir l'extrémité de la vis (50), extrémité pouvant être par exemple vissée et collée dans le pivot (23).- The pivot (23), with reference to Figure 10, can also if its size allows it to receive the end of the screw (50), end can be for example screwed and glued into the pivot (23).
Selon l'invention un moyen de blocage mettant en œuvre un élément mobile guidé permet de bloquer la rotation de l'excentrique (8) par rapport à son pivotAccording to the invention a locking means implementing a guided mobile element makes it possible to block the rotation of the eccentric (8) relative to its pivot
(23). L'élément mobile guidé se déplaçant sous l'action conjuguée de son propre poids et du retournement sur lui-même et de 180° dudit moyen de blocage dans deux positions de travail différentes. L'élément mobile occupe une première position de travail lorsque la bicyclette est dans une position retournée, qui permet à l'excentrique (8) de tourner librement autour de son pivot (23). Première position autorisant les manœuvres de serrage et de desserrage du dispositif antivol - blocage rapide (1). L'élément mobile occupe une deuxième position de travail lorsque la bicyclette est dans une position normale et que le dispositif antivol - blocage rapide (1) est en position serrée, qui bloque et interdit à l'excentrique (8) de tourner autour de son pivot (23). Deuxième position ne permettant plus les manœuvres de serrage et de desserrage du dispositif antivol - blocage rapide (1).(23). The guided mobile element moving under the combined action of its own weight and the turning on itself and 180 ° of said locking means in two different working positions. The movable member occupies a first working position when the bicycle is in an upturned position, which allows the eccentric (8) to rotate freely about its pivot (23). First position allowing the tightening and loosening of the antitheft device - quick release (1). The movable member occupies a second working position when the bicycle is in a normal position and the antitheft device - quick release (1) is in a tight position, which blocks and prevents the eccentric (8) from rotating around its pivot (23). Second position no longer allowing the tightening and loosening of the antitheft device - quick release (1).
Afin de protéger l'élément mobile des agressions extérieures du type poussière, boue, et eau, on équipe selon l'invention Ie moyen de blocage d'un moyen d'étanchéité.In order to protect the mobile element from external aggression of the dust, mud and water type, the locking means of a means according to the invention are equipped according to the invention. sealing.
L'invention retient quatre principales solutions pour réaliser le moyen de blocage dont l'originalité est d'être activé ou désactivé par retournement de la bicyclette. Première solution, illustrée par les figures 4 et 5 dans laquelle l'élément mobile est une goupille (42) cylindrique guidé en translation. Dans cette première solution une tête (24) cylindrique prolonge Ie pivot (23), cette tête (24) concentrique au pivot (23) est pourvue d'un perçage (25) cylindrique non débouchant sur l'extérieur et présentant une profondeur supérieure à la longueur de la goupille (42). Un bossage (10) cylindrique concentrique au pivot (23) prolonge l'excentrique (8) et vient au contact de la tête (24). Ce bossage (10) est également pourvu d'un perçage (11) cylindrique non débouchant et d'une profondeur inférieure à la longueur de la goupille (42) et ne pouvant donc accueillir que partiellement la goupille (42). Selon l'invention le perçage (25) et le perçage (11) sont situés sur un même diamètre et se retrouvent concentriques et opposés lorsque le dispositif antivol - blocage rapide (1) est en position serré. La protection de la goupille (42) par rapport aux agressions extérieure est réalisée au moyen du joint d'étanchéité (26) et du joint d'étanchéité (27). Le joint d'étanchéité (27) prend place entre le pivot (23) et l'excentrique (8), le joint d'étanchéité (26) prend place entre la tête (24) et le bossage (10). La figure 4 représente le moyen de blocage lorsque la bicyclette est dans une position normale et le dispositif antivol - blocage rapide (1) serré. On observe que la goupille (42) est engagée partiellement dans le perçage (25) provoquant le blocage en rotation de l'excentrique (8) par rapport au pivot (23). Pour désactiver le blocage en rotation de l'excentrique (8) par rapport au pivot (23) il suffit selon l'invention de retourner la bicyclette afin que la goupille (42) quitte le perçage (11) et vienne se loger entièrement dans le perçage (25).The invention retains four main solutions to achieve the locking means whose originality is to be activated or deactivated by turning the bicycle. First solution, illustrated in Figures 4 and 5 wherein the movable member is a pin (42) cylindrical guided in translation. In this first solution a cylindrical head (24) extends the pivot (23), this head (24) concentric with the pivot (23) is provided with a bore (25) cylindrical non-opening on the outside and having a depth greater than the length of the pin (42). A cylindrical boss (10) concentric with the pivot (23) extends the eccentric (8) and comes into contact with the head (24). This boss (10) is also provided with a bore (11) cylindrical non-opening and a depth less than the length of the pin (42) and can therefore only partially accommodate the pin (42). According to the invention the bore (25) and the bore (11) are located on the same diameter and are found concentric and opposite when the anti-theft device - quick release (1) is in the tight position. The protection of the pin (42) with respect to external aggressions is achieved by means of the seal (26) and the seal (27). The seal (27) takes place between the pivot (23) and the eccentric (8), the seal (26) takes place between the head (24) and the boss (10). Figure 4 shows the locking means when the bicycle is in a normal position and the anti-theft device - quick release (1) tight. It is observed that the pin (42) is partially engaged in the bore (25) causing the rotational locking of the eccentric (8) relative to the pivot (23). To deactivate the locking in rotation of the eccentric (8) with respect to the pivot (23) it suffices according to the invention to turn the bicycle so that the pin (42) leaves the bore (11) and comes to lodge entirely in the piercing (25).
Selon une variante de cette première solution, la longueur du perçage (25) est inférieure à la longueur de la goupille (42) et la longueur du perçage (11) est supérieure à la longueur de la goupille (42). Dans cette variante le moyen de blocage se situe non plus en partie haute mais en partie basse du dispositif antivol - blocage rapide (1) lorsque la bicyclette est dans une position normale.According to a variant of this first solution, the length of the bore (25) is less than the length of the pin (42) and the length of the bore (11) is greater than the length of the pin (42). In this variant the locking means is no longer in the upper part but in the lower part of the antitheft device - quick release (1) when the bicycle is in a normal position.
Différentes variantes permettent d'améliorer la fiabilité du moyen de blocage à goupille (42). Ainsi figure 6 on multiplie le nombre de goupilles (42). Figure 7 on introduit un amortisseur (48) entre la goupille (42) et le fond du perçage (11) du bossage (10) afin de rendre le dispositif antivol - blocage rapide (1) insensible aux chocs et secousses. Cet amortisseur (48) pouvant être par exemple soit un ressort, soit un élément en caoutchouc. Figure 8 on introduit une bille (47) entre la goupille (42) et le fond du perçage (25) de la tête du pivot (23) afin également de rendre le dispositif antivol - blocage rapide (1) insensible aux chocs et secousses. Figure 9 quatre goupilles (42) avec leurs perçages (25) et perçages (11) associés viennent former une pyramide centrée sur l'axe (9) de la tête et du bossage, l'angle de la pyramide ayant une valeur choisie entre 45 et 90 °. On dispose avec cette dernière variante d'une solution obligeant à retourner la bicyclette dans une position parfaitement verticale pour permettre le déblocage du dispositif antivol - blocage rapide (1).Different variants make it possible to improve the reliability of the pin locking means (42). Thus, FIG. 6 multiplies the number of pins (42). Figure 7 on introduces a damper (48) between the pin (42) and the bottom of the bore (11) of the boss (10) in order to make the antitheft device - quick release (1) insensitive to shocks and jolts. This damper (48) can be for example a spring or a rubber element. Figure 8 is introduced a ball (47) between the pin (42) and the bottom of the bore (25) of the head of the pivot (23) also to make the antitheft device - fast blocking (1) insensitive to shocks and jolts. Figure 9 four pins (42) with their bores (25) and holes (11) associated form a pyramid centered on the axis (9) of the head and the boss, the angle of the pyramid having a value chosen between 45 and 90 °. With this latter variant, there is a solution requiring the bicycle to be returned to a perfectly vertical position to enable unlocking of the antitheft device - quick release (1).
Deuxième solution pour réaliser le moyen de blocage, illustrée par les figures 10 et 11 dans laquelle l'élément mobile est une clavette (43) de section carrée guidée en translation. Dans cette deuxième solution, un tourillon (28) prolonge le pivot (23), ce tourillon (28) concentrique à l'axe (9) du pivot (23) est pourvu d'une rainure (29) de section carrée et d'un dégagement (30) cylindrique également concentrique à l'axe (9). Un boîtier (12) cylindrique et fermé prolonge l'excentrique (8), ce boîtier (12) concentrique à l'axe (9) accueille d'une part le tourillon (23) et est pourvu d'autre part d'une rainure (13). La rainure (29) et la rainure (13) sont de section identique à la section de la clavette (43) et sont toute deux parallèles à l'axe (9). La clavette (43) prend place et peut coulisser librement dans la rainure (13). La protection de la clavette (43) par rapport aux agressions extérieures est réalisée au moyen du joint d'étanchéité (27). Le joint d'étanchéité (27) prenant place entre le pivot (23) et l'excentrique (8).Second solution for producing the locking means, illustrated by Figures 10 and 11 wherein the movable member is a key (43) of square section guided in translation. In this second solution, a pin (28) extends the pivot (23), this pin (28) concentric with the axis (9) of the pivot (23) is provided with a groove (29) of square section and a clearance (30) cylindrical also concentric with the axis (9). A housing (12) cylindrical and closed extends the eccentric (8), this housing (12) concentric with the axis (9) accommodates on the one hand the pin (23) and is provided on the other hand with a groove (13). The groove (29) and the groove (13) are of identical section to the section of the key (43) and are both parallel to the axis (9). The key (43) takes place and can slide freely in the groove (13). The protection of the key (43) with respect to the external aggressions is achieved by means of the seal (27). The seal (27) taking place between the pivot (23) and the eccentric (8).
La figure 10 représente le moyen de blocage alors que la bicyclette est dans une position normale et le dispositif antivol - blocage rapide (1) serré. On observe que la clavette (43) est engagée simultanément dans la rainure (13) et dans la rainure (29) provoquant Ie blocage en rotation de l'excentrique (8) par rapport au pivot (23). Pour désactiver le blocage en rotation de l'excentrique (8) par rapport au pivot (23) il suffit selon l'invention de retourner la bicyclette afin que la clavette (43) quitte la rainure (29) et vienne se loger entièrement dans le fond (14) de rainure (13) et le dégagement (30). Selon une variante de cette deuxième solution on inverse les deux parties du tourillon (28), afin que le dégagement (30) se trouve proche du joint (27) et la rainure (29) proche du fond de boîtier (12). Dans cette variante le moyen de blocage se situe non plus en partie haute mais en partie basse du dispositif antivol - blocage rapide (1) lorsque la bicyclette est dans une position normale.Figure 10 shows the locking means while the bicycle is in a normal position and the antitheft device - quick release (1) tight. It is observed that the key (43) is engaged simultaneously in the groove (13) and in the groove (29) causing the rotational locking of the eccentric (8) relative to the pivot (23). To deactivate the locking in rotation of the eccentric (8) relative to the pivot (23) it suffices according to the invention to turn the bicycle so that the key (43) leaves the groove (29) and is housed entirely in the groove bottom (14) (13) and clearance (30). According to a variant of this second solution is reversed the two parts of the pin (28), so that the clearance (30) is close to the seal (27) and the groove (29) near the housing bottom (12). In this variant the locking means is no longer in the upper part but in the lower part of the antitheft device - quick release (1) when the bicycle is in a normal position.
Différentes variantes permettent d'améliorer la fiabilité du moyen de blocage à clavette (43). Ainsi figure 12 la clavette (43) est coupée en plusieurs morceaux et ainsi figure 13 la clavette (43) est remplacée par des billes d'un diamètre égal à la largeur de la rainure (19). Troisième solution pour réaliser le moyen de blocage illustrée par les figures 14 et 15 dans laquelle l'élément mobile est une rondelle crénelée (44) guidée en translation.

La protection de la rondelle (44) par rapport aux agressions extérieures est réalisée au moyen du joint d'étanchéité (27). Le joint d'étanchéité (27) prenant place entre le pivot (23) et l'excentrique (8).Various variants make it possible to improve the reliability of the key locking means (43). Thus Figure 12 the key (43) is cut into several pieces and thus Figure 13 the key (43) is replaced by balls with a diameter equal to the width of the groove (19). Third solution for producing the locking means illustrated in Figures 14 and 15 wherein the movable member is a crenelated washer (44) guided in translation. In this third solution, a tip (31) of square section concentric with the axis (9) extends the pivot (23). The crenellated washer (44) pierced with a hole of square section is engaged on the end piece (31) on which it can slide freely without turning. A casing (15) cylindrical and closed extends the eccentric (8), this housing (15) integral with the eccentric (8) and concentric with the axis (9) covers without contact the tip (31) and the washer (44) crenellated. A second crenellated washer (17) pierced with a cylindrical hole and engaged on the endpiece (31) is integral with the eccentric (8) while leaving the pivot (23) free to rotate.
