Abstract

The invention concerns a device (1) for stabilising a two-wheeled vehicle such as a scooter, comprising retractable stands (2A, 2B) arranged on either side of said vehicle, members (5, 6) for controlling said stands between a first state wherein they are retracted, and a second state wherein they are in stabilising contact with the ground. The control members comprise a lever mechanism connected to the stands and accessible on the vehicle footrest such that said lever mechanism can be actuated by the rider's feet in riding position. A pressure exerted frontwards by at least one foot of the rider on said lever mechanism produces the first retracted state whereas a pressure exerted rearwards on said lever mechanism produces the second stabilising state.

Description

"Dispositif pour stabiliser un véhicule à deux roues, notamment un scooter, et véhicule à deux roues ainsi équipé" "Device for stabilizing a two-wheeled vehicle, in particular a scooter, and two-wheeled vehicle thus equipped"
DESCRIPTION La présente invention concerne un dispositif pour stabiliser un véhicule à deux roues, notamment un scooter. Elle vise également un véhicule à deux roues équipé de ce dispositif de stabilisation.DESCRIPTION The present invention relates to a device for stabilizing a two-wheeled vehicle, in particular a scooter. It also relates to a two-wheeled vehicle equipped with this stabilization device.
Les scooters actuels sont généralement équipés d'une béquille centrale de stabilisation en position verticale, qui ne peut être actionnée qu'à l'arrêt, le conducteur du scooter devant être impérativement descendu de la plateforme de son véhicule et devant effectuer une manœuvre combinant un mouvement de déplacement du scooter à l'aide de ses mains et un mouvement de positionnement de la béquille centrale à l'aide de son pied. Or cette manœuvre s'avère pénible et parfois délicate, car il s'agit en fait de soulever au moins partiellement le scooter autour du point d'appui de la béquille centrale sur le sol, cette opération demandant au conducteur des efforts qu'il n'est parfois pas en mesure de fournir dans de bonnes conditions .Current scooters are generally equipped with a central stabilizing stand in a vertical position, which can only be actuated when stationary, the driver of the scooter must be removed from the platform of his vehicle and must perform a maneuver combining a movement of movement of the scooter using his hands and a movement of positioning the center stand using his foot. However, this maneuver proves painful and sometimes delicate, because it is in fact at least partially lifting the scooter around the fulcrum of the center stand on the ground, this operation requiring the driver of the efforts that n 'is sometimes unable to provide in good conditions.
On connaît déjà plusieurs dispositifs de stabilisation pour motocycles, mettant en œuvre des actionneurs électriques ou hydrauliques commandant une ou plusieurs béquilles escamotables. Les opérations de descente et de remontée des béquilles escamotables sont commandées soit par le conducteur, soit automatiquement en fonction de paramètres de conduite tels que de la vitesse du véhicule.Several stabilization devices for motorcycles are already known, using electrical or hydraulic actuators controlling one or more retractable stands. The lowering and raising operations of the retractable stands are controlled either by the driver or automatically depending on driving parameters such as the speed of the vehicle.
Le document FR1249598 divulgue ainsi un dispositif de béquilles stabilisatrices pour cyclomoteur comprenant une tige mobile en rotation dans un palier situé dans l'axe de rotation de la roue arrière du cyclomoteur, cette tige se terminant par deux bras de béquille pourvus à leurs extrémités de roulettes et étant commandée par un système de commande incluant une barre de levier, deux biellettes et une pédale de commande.Document FR1249598 thus discloses a device for stabilizing crutches for a moped comprising a rod movable in rotation in a bearing located in the axis of rotation of the rear wheel of the moped, this rod ending in two crutch arms provided at their ends with rollers and being controlled by a control system including a lever bar, two links and a foot control.
On connaît par ailleurs, par le document FR2735745 correspondant au brevet français n°9507517 au nom du présent déposant, un dispositif de stabilisation mettant en œuvre une technique dite de retour d'effort par laquelle le conducteur ressent au niveau des moyens de commande les efforts de réaction du sol auxquels sont effectivement soumis les béquilles équipées de roulettes lorsqu'elles sont en position basse. Grâce au retour d'effort, le dispositif de stabilisation peut en quelque sorte doser et réguler les forces d' application des béquilles, ce qui contribue à un accroissement significatif du confort d'utilisation de ce dispositif de stabilisation . Cependant, les dispositifs de stabilisation proposés jusqu'à présent sont de réalisation complexe, car ils mettent en œuvre des asservissements, des actionneurs commandés, et des systèmes de commande relativement sophistiques, ce qui peut conduire à des coûts exorbitants, notamment pour des scooters d'entrée de gamme ou de moyenne gamme .We also know, from document FR2735745 corresponding to French patent n ° 9507517 in the name of the present applicant, a stabilization device implementing a technique known as force feedback by which the driver feels the efforts reaction of the ground to which the crutches fitted with castors are actually subjected when they are in the low position. Thanks to the force feedback, the stabilization device can in a way measure and regulate the application forces of the crutches, which contributes to a significant increase in the comfort of use of this stabilization device. However, the stabilization devices proposed so far are complex to realize, because they use servo drives, controlled actuators, and relatively sophisticated control systems, which can lead to exorbitant costs, in particular for scooters of entry-level or mid-range.
Le but de l'invention est de remédier à cet inconvénient en proposant un dispositif de stabilisation pour un véhicule à deux roues, notamment un scooter, qui procure les effets techniques attendus avec des moyens mécaniques simples et robustes. Cet objectif est atteint avec un dispositif pour stabiliser un véhicule a deux roues tel qu'un scooter, comprenant :The object of the invention is to remedy this drawback by proposing a stabilization device for a two-wheeled vehicle, in particular a scooter, which provides the expected technical effects with simple and robust mechanical means. This objective is achieved with a device for stabilizing a two-wheeled vehicle such as a scooter, comprising:
- des premiers et seconds moyens de béquille escamotables disposés de part et d'autre dudit véhicule, et comprenant chacun un premier et un seconds bras comportant à son extrémité une roulette,- first and second retractable stand means arranged on either side of said vehicle, and each comprising a first and a second arm comprising at its end a caster,
- des moyens pour commander par au moins un pied du pilote lesdits premiers et seconds moyens de béquille entre un premier état dans lequel lesdits premiers et seconds moyens de béquille sont escamotés, et un second état dans lequel lesdits premiers et seconds moyens de béquille sont en contact de stabilisation avec le sol, lesdits premier et second bras étant reliés mécaniquement et mobiles par rapport à un axe de rotation lié au châssis du véhicule.- Means for controlling by at least one foot of the pilot said first and second crutch means between a first state in which said first and second crutch means are retracted, and a second state in which said first and second crutch means are in stabilization contact with the ground, said first and second arms being mechanically connected and movable relative to an axis of rotation linked to the chassis of the vehicle.
Suivant l'invention, les moyens de commande comprennent des moyens de levier solidaires d' au moins un des bras au dessus dudit axe de rotation, ces moyens de levier étant accessibles par au moins un pied du pilote depuis le repose-pied dudit véhicule et agencés de sorte qu'une pression exercée vers l'avant par au moins un pied du pilote sur ces moyens de levier conduit au premier état d'escamotage tandis qu'une pression exercée vers l'arriére par au moins un pied dudit pilote sur lesdits moyens de levier conduit au second état de stabilisation.According to the invention, the control means comprise lever means integral with at least one of the arms above said axis of rotation, these lever means being accessible by at least one foot of the driver from the footrest of said vehicle and arranged so that a pressure exerted forwards by at least one foot of the pilot on these lever means leads to the first state of retraction while a pressure exerted towards the rear by at least one foot of said pilot on said lever means leads to the second stabilization state.
Avec le dispositif de stabilisation selon l'invention, le pilote dispose, à travers la pression qu'il exerce vers l'arriére sur le ou les leviers αe commande lorsque les béquilles latérales sont en position basse, d'un réel retour d'effort qui lui procure une sensation agréable et sécurisante et représente une solution concrète au problème du contrôle par le pilote de la stabilité de son véhicule à basse vitesse. Par ailleurs, la structure particulièrement simple du dispositif de stabilisation selon l'invention constitue une solution radicale au problème récurrent de poids et de coût rencontré dans toutes les solutions techniques proposées antérieurement et qui a constitué jusqu'à présent un obstacle rédhibitoire à leur développement. En particulier, le nombre de pièces et d'organes nécessaires pour réaliser le dispositif de stabilisation selon l'invention est significativement réduit par rapport aux dispositifs de stabilisation de l'art antérieur.With the stabilization device according to the invention, the pilot has, through the pressure he exerts towards the rear on the lever (s) αe controls when the side stands are in the low position, a real force feedback which gives it a pleasant and reassuring feeling and represents a concrete solution to the problem of pilot control of the stability of his vehicle at low speed. Furthermore, the particularly simple structure of the stabilization device according to the invention constitutes a radical solution to the recurring problem of weight and cost encountered in all the technical solutions proposed previously and which has hitherto constituted a prohibitive obstacle to their development. In particular, the number of parts and members required to produce the stabilization device according to the invention is significantly reduced compared to the stabilization devices of the prior art.
Il est à noter que le dispositif de stabilisation selon 1 ' invention trouve tout son intérêt dans une utilisation urbaine avec des arrêts de très courte durée et répétés .It should be noted that the stabilization device according to the invention finds all its advantage in urban use with very short and repeated stops.
Il faut également souligner que, l'angle à balayer par les bras de béquille pouvant être supérieur à 90 degrés, le dispositif de stabilisation selon l'invention procure avantageusement un balayage automatique de cet angle de la position haute à la position basse et inversement .It should also be emphasized that, since the angle to be swept by the stand arms may be greater than 90 degrees, the stabilization device according to the invention advantageously provides automatic scanning of this angle from the high position to the low position and vice versa.
Le balayage angulaire correspondant au passage de la position haute à la position basse est effectué principalement par gravité, dès que les pieds du pilote cessent de se reposer sur les moyens de commande. Il ne reste plus alors qu'une petite pression a exercer pour terminer le balayage angulaire.The angular scanning corresponding to the passage from the high position to the low position is carried out mainly by gravity, as soon as the pilot's feet cease to rest on the control means. There is then only a small pressure to exert to complete the angular scan.
De la position basse à la position haute, au redémarrage, le ou les pieds du pilote quittent les moyens de commande et l'avancement du véhicule permet aux deux bras de béquille de parcourir dans l'autre sens une partie non négligeable de l'angle de balayage qui sera finalement complète par la pose des pieds du pilote sur les moyens de commande en régime de croisière.From the low position to the high position, on restarting, the driver's foot (s) leave the control means and the advancement of the vehicle allows the two stand arms to travel in the other direction a significant part of the sweep angle which will ultimately be completed by placing the pilot's feet on the cruise control means.
Dans une première variante de réalisation, les moyens de levier sont reliés a leurs extrémités par une barre de commande sensiblement parallèle a l'axe de rotation et actionnable par les pieds du pilote, les bras de béquille pouvant être relies mécaniquement ou non par une pièce d'axe de rotation ou barre de liaison axiale. Dans une seconde variante de réalisation, les deux bras sont agencés pour être mobiles en rotation indépendamment l'un de l'autre autour d'un axe de rotation lié au châssis du véhicule, et les premiers et seconds moyens de levier sont reliés à leur extrémité à une pièce commune faisant fonction de barre de torsion et de flexion. Cette variante de réalisation procure un contrôle différentiel des deux béquilles, le pilote pouvant exercer avec chacun de ses pieds une pression différente sur l'une et l'autre des parties de levier. Les bras de béquille sont alors décales angulairement . On peut ainsi compenser les effets d'inclinaison transversale de certaines chaussées.In a first alternative embodiment, the lever means are connected at their ends by a control bar substantially parallel to the axis of rotation and actuable by the feet of the pilot, the stand arms being able to be connected mechanically or not by a piece axis of rotation or axial connecting bar. In a second variant embodiment, the two arms are arranged to be movable in rotation independently of one another around an axis of rotation linked to the chassis of the vehicle, and the first and second lever means are connected to their end to a common part acting as a torsion and bending bar. This variant embodiment provides differential control of the two crutches, the pilot being able to exert different pressure on each of the lever parts with each of his feet. The stand arms are then angularly offset. We can thus compensate for the transverse tilting effects of certain roadways.
Dans une troisième variante de réalisation, les premier et second bras de béquille sont relies mécaniquement par une pièce d'axe de rotation ou barre de liaison axiale mobile angulairement selon l'axe de rotation et un seul levier de commande droit ou gauche est fourni en prolongement de l'un des bras de béquille.In a third alternative embodiment, the first and second stand arms are mechanically connected by a part with an axis of rotation or an axial connecting bar movable angularly along the axis of rotation and a single right or left control lever is provided. extension of one of the stand arms.
Par ailleurs, les moyens de béquille peuvent être agences de façon a procurer momentanément un soulèvement du châssis du véhicule et de son pilote lors du passage des premiers et seconds moyens de béquille d'un état à 1 ' autre .Furthermore, the stand means can be arranged so as to temporarily lift the chassis of the vehicle and its driver when passing first and second stand means from one state to another.
Ainsi, avec le dispositif de stabilisation selon l'invention, le pilote d'un scooter peut obtenir une mise en place des béquilles à basse vitesse jusqu'à l'arrêt de son véhicule qui est soulevé momentanément, ce qu supprime par conséquent la manœuvre difficile de mise sur béquille centrale qui était jusqu'à présente incontournable . On peut également prévoir un dispositif de stabilisation selon l'invention dans lequel les moyens de commande comprennent des premiers moyens faisant pédale pour placer et maintenir les premiers et seconds moyens de béquille en position escamotée, et des seconds moyens faisant pédale pour placer et maintenir lesdits premiers et seconds moyens de béquille en position de stabilisation, ces premiers et seconds moyens faisant pédale étant fixés solidairement à un axe de rotation auquel les premiers et seconds moyens de béquille sont reliés.Thus, with the stabilization device according to the invention, the pilot of a scooter can obtain the positioning of crutches at low speed until the stopping of his vehicle which is lifted momentarily, which consequently eliminates the maneuver. difficult to put on center stand which was until now essential. One can also provide a stabilization device according to the invention in which the control means comprise first means acting as a pedal to place and maintain the first and second stand means in the retracted position, and second means acting as a pedal to place and maintain said means first and second stand means in the stabilization position, these first and second pedal means being fixedly attached to an axis of rotation to which the first and second stand means are connected.
Les bras respectifs des premiers et seconds moyens de béquille peuvent avantageusement comporter chacun un coude au dessus de l'axe de liaison, les parties de bras situées au dessus desdits coudes étant agencées pour constituer des moyens de commande par levier actionnables par les pieds du pilote.The respective arms of the first and second stand means may advantageously each include an elbow above the connecting axis, the arm parts located above said elbows being arranged to constitute lever control means actuable by the feet of the pilot. .
Il est important de noter que la longueur entre l'extrémité de contact de chaque bras et l'axe de liaison est de préférence réglable en fonction de divers paramètres de fonctionnement tels que le poids du pilote, de sorte que, lorsque les bras sont dans une position sensiblement verticale, le châssis du scooter se trouve sensiblement soulevé par rapport a sa position d'équilibre dans laquelle les moyens de béquille sont escamotés. Par ailleurs, les longueurs respectives du bras de béquille gauche et du bras de béquille droit peuvent être choisies différentes, avec par exemple un bras de béquille droit plus long de 5 mm que le bras de béquille gauche, pour tenir compte d'une inclinaison transversale des chaussées dans les régions de circulation à droite. Il va de soi que dans les régions de circulation à gauche, on choisira un bras de béquille gauche légèrement plus long que le bras de béquille droit .It is important to note that the length between the contact end of each arm and the connecting axis is preferably adjustable according to various operating parameters such as the weight of the pilot, so that when the arms are in a substantially vertical position, the scooter chassis is substantially raised relative to its equilibrium position in which the stand means are retracted. In addition, the respective lengths of the left stand arm and the right stand arm can be chosen different, for example with a right stand arm 5 mm longer than the left stand arm, to allow for a transverse tilt. roadways in traffic areas on the right. It goes without saying that in left-hand traffic regions, a left crutch arm will be chosen slightly longer than the right crutch arm.
On peut également prévoir de munir le dispositif de stabilisation selon l'invention de premiers moyens de rappel disposés entre des moyens de béquille et le châssis du scooter de façon à maintenir lesdits moyens de béquille en position escamotée après une commande d'escamotage exercée sur les moyens de commande.It is also possible to provide the stabilization device according to the invention with first return means arranged between stand means and the chassis of the scooter so as to maintain said stand means in the retracted position after a retraction command exerted on the control means.
De même, on peut prévoir des seconds moyens de rappel disposes entre des moyens de béquille et le châssis du scooter de façon à maintenir lesdits moyens de béquille en position de stabilisation, après une action de stabilisation exercée sur les moyens de commande.Similarly, it is possible to provide second return means arranged between stand means and the chassis of the scooter so as to maintain said stand means in the stabilization position, after a stabilization action exerted on the control means.
Ces premiers et seconds moyens de rappel peuvent par exemple être réalisés sous la forme d'un ressort à deux positions fixé entre le châssis du scooter et l'un et/ou l'autre des moyens de béquille.These first and second return means can for example be made in the form of a spring with two positions fixed between the chassis of the scooter and one and / or the other of the stand means.
Une option de sécurité peut inclure des premiers moyens pour verrouiller les premiers et seconds moyens de béquille en position escamotée, ainsi que des seconds moyens pour verrouiller les premiers et seconds moyens de béquille en position basse de stabilisation, notamment pour le mode "parking" .A security option may include first means for locking the first and second stand means in the retracted position, as well as second means for locking the first and second means for stand in the low stabilization position, especially for "parking" mode.
Suivant un autre aspect de l'invention, il est proposé un véhicule à deux roues équipe d'un dispositif de stabilisation selon l'invention, comprenant un châssis ou cadre adapté pour recevoir un axe de rotation de deux premier et second bras appartenant respectivement a deux premier et second moyens de béquille escamotables disposés de part et d'autre dudit véhicule. Ce véhicule a deux roues comprend en outre des moyens de levier solidaires d' au moins un des bras au dessus de l'axe de rotation, ces moyens de levier étant accessibles par au moins un pied du pilote depuis le repose-pied dudit véhicule et agencés de sorte qu'une pression exercée vers l'avant par au moins un pied du pilote sur ces moyens de levier conduit à un état d'escamotage tandis qu'une pression exercée vers l'arrière par au moins un pied dudit pilote sur lesdits moyens de levier conduit à un état de stabilisation. Lorsque ce véhicule est un cyclomoteur pourvu d'un réservoir de carburant dispose le long d'un élément du cadre de ce cyclomoteur, on peut prévoir une configuration particulière dans laquelle l'axe de rotation des bras de béquille traverse ce réservoir. Si cet axe est effectivement matérialisé par une pièce mécanique d'axe de rotation, le réservoir doit alors présenter une structure et une forme appropriées pour permettre le passage de cette pièce d'axe. On peut par exemple prévoir une forme particulière du réservoir agencée pour contourner ou envelopper la pièce d' axe de rotation ou barre de liaison axiale, ou encore une forme de réservoir entourant ou encerclant complètement la pièce d'axe de rotation ou barre de liaison axiale.According to another aspect of the invention, there is provided a two-wheeled vehicle equipped with a stabilization device according to the invention, comprising a chassis or frame adapted to receive an axis of rotation of two first and second arms belonging respectively to two first and second retractable stand means arranged on either side of said vehicle. This two-wheeled vehicle further comprises lever means integral with at least one of the arms above the axis of rotation, these lever means being accessible by at least one foot of the driver from the footrest of said vehicle and arranged so that a pressure exerted forward by at least one foot of the pilot on these lever means leads to a state of retraction while a pressure exerted rearward by at least one foot of said pilot on said leverage means leads to a state of stabilization. When this vehicle is a moped provided with a fuel tank arranged along an element of the frame of this moped, provision may be made for a particular configuration in which the axis of rotation of the stand arms passes through this tank. If this axis is effectively materialized by a mechanical part with an axis of rotation, the reservoir must then have an appropriate structure and shape to allow the passage of this axis part. One can for example provide a particular shape of the tank arranged to bypass or wrap the part of the axis of rotation or axial connecting bar, or even a shape of tank completely surrounding or encircling the part of axis of rotation or axial connecting bar.
D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-apres .

In the accompanying drawings given by way of nonlimiting examples: FIG. 1 schematically illustrates a scooter fitted with a stabilization device according to the invention, in three characteristic situations; - Figure 2 illustrates a first embodiment of a stabilization device according to the invention; FIG. 3 illustrates a second embodiment of a stabilization device according to the invention; FIG. 4 illustrates a third embodiment of a stabilization device according to the invention; and FIG. 5 illustrates the variations in attitude of a scooter fitted with a stabilization device according to the invention, in a complete cycle of use.
On va en premier lieu décrire la structure de base et le fonctionnement d'un dispositif de stabilisation selon l'invention, en référence a la figure 1.We will first describe the basic structure and the operation of a stabilization device according to the invention, with reference to FIG. 1.
Le dispositif de stabilisation 1 installe sur un scooter comprend de part et d'autre du repose-pied de ce scooter des béquilles 2 équipées de roulettes 3, montées librement en rotation autour d'un axe 4, et prolongées a leur extrémité supérieure par des pièces de levier 5 reliées par une barre de commande 6 s' étendant, dans le cas du scooter, au dessus du repose-pied. En régime de croisière (I), les pieds du pilote sont en appui sur la barre de commande 6 de telle sorte que les béquilles 2 sont en position relevée ou escamotée.The stabilization device 1 installed on a scooter comprises on either side of the footrest of this scooter crutches 2 equipped with casters 3, mounted freely in rotation about an axis 4, and extended at their upper end by lever parts 5 connected by a control bar 6 extending, in the case of the scooter, above the footrest. In cruising mode (I), the pilot's feet are supported on the control bar 6 so that the crutches 2 are in the raised or retracted position.
En situation de décélération (II), le pilote libère en soulevant ses pieds la barre de commande 6, ce qui provoque la descente des béquilles par un mouvement de rotation autour de l'axe 4 jusqu'à l'entrée en contact des roulettes 3 avec le sol. Le pilote exerce alors avec ses pieds une pression sur la barre de commande 6 en position de stabilisation, ce qui a pour effet de légèrement soulever le châssis du scooter par rapport à son assiette de croisière. Les oéquilles peuvent passer momentanément en position verticale puis dépassent cette position verticale pour atteindre une position de butée (III) .In a deceleration situation (II), the pilot releases by lifting his feet the control bar 6, which causes the crutches to descend by a rotational movement around the axis 4 until the wheels 3 come into contact. with the ground. The pilot then exerts pressure with his feet on the control bar 6 in the stabilization position, which has the effect of slightly lifting the chassis of the scooter with respect to its cruise attitude. The eyelets can temporarily move to the vertical position and then exceed this vertical position to reach a stop position (III).
On va maintenant décrire une première variante de réalisation d'un dispositif de stabilisation, en référence à la figure 2. Le dispositif de stabilisation 1 comporte deux béquilles 2A, 2B parallèles pourvues à leurs extrémités inférieures de roulettes 3A, 3B. Ces deux béquilles, réalisées par exemple à partir de tubes, de plats ou de profilés en alliage ou en acier, sont reliées d'une part à une barre de liaison axiale 8 insérée par exemple dans un tube support 7 solidaire du châssis ou du repose-pied du scooter, et d'autre part à une barre de commande 6 par des parties de levier 5A, 5B coudées par rapport aux parties principales αes béquilles 2A, 2B. Les parties de levier et la barre de commande peuvent être réalisées à partir d'une pièce tubulaire unique. La structure mécanique rigide constituée par les deux béquilles 2A, 2B, la barre de liaison axiale 8 et la barre de commande 6 est mobile en rotation autour de 1 ' axe 4.We will now describe a first embodiment of a stabilization device, with reference to Figure 2. The stabilization device 1 comprises two crutches 2A, 2B parallel provided at their lower ends with rollers 3A, 3B. These two crutches, made for example from tubes, dishes or profiles of alloy or steel, are connected on the one hand to an axial connecting bar 8 inserted for example in a support tube 7 secured to the chassis or the rest -foot of the scooter, and on the other hand to a control bar 6 by lever parts 5A, 5B bent relative to the main parts αes crutches 2A, 2B. The lever parts and the control bar can be produced from a single tubular part. The rigid mechanical structure constituted by the two crutches 2A, 2B, the axial connecting bar 8 and the control bar 6 is movable in rotation about the axis 4.
Dans une seconde variante de réalisation représentée en figure 3, les parties de levier coudées 5A, 5B du dispositif de stabilisation 10 ne sont pas reliées solidairement par une barre de commande, mais comprennent des pièces de liaison 50A, 50B en liaison coulissante avec une barre de torsion 12. Les bras de levier 2A, 2B sont agencés pour être mobiles en rotation indépendamment l'un de l'autre autour d'un axe de rotation 9 solidaire du châssis du scooter. Cet agencement particulier permet une action indépendante sur chacune des béquilles, notamment pour la prise en compte d'irrégularités du sol.In a second alternative embodiment shown in FIG. 3, the angled lever parts 5A, 5B of the stabilization device 10 are not connected integrally by a control bar, but comprise connecting parts 50A, 50B in sliding connection with a bar torsion 12. The lever arms 2A, 2B are arranged to be movable in rotation independently of one another about an axis of rotation 9 secured to the chassis of the scooter. This particular arrangement allows independent action on each of the crutches, in particular for taking account of irregularities in the ground.
Dans une troisième variante de réalisation représentée en figure 4, une seule partie de levier 5C du dispositif de stabilisation 100 est fournie en prolongement d'un bras de béquille 2B reliée solidement à l'autre bras de béquille 2A par une pièce d'axe de rotation ou barre de liaison axiale 8 mobile dans un tube de liaison 7 fixé au châssis. L'effort exercé par le pied du pilote sur la partie de levier 5C est transmis directement au bras de béquille ainsi prolongé et indirectement à l'autre bras de béquille par l'intermédiaire de la pièce d'axe de rotation ou barre de liaison axiale.In a third alternative embodiment shown in FIG. 4, a single lever part 5C of the stabilization device 100 is provided as an extension of a stand arm 2B securely connected to the other stand arm 2A by a piece of axle rotation or axial connecting bar 8 movable in a connecting tube 7 fixed to the chassis. The force exerted by the pilot's foot on the lever part 5C is transmitted directly to the crutch arm thus extended and indirectly to the other crutch arm via the part of the axis of rotation or axial link bar .
Une caractéristique importante du dispositif de stabilisation selon l'invention réside dans le fait que sa mise en œuvre a pour effet de soulever ponctuellement le châssis du scooter par rapport à sa position normale d'utilisation. Ces situations de soulèvement ponctuel d'une part permettent de placer un scooter sur αes béquilles beaucoup moins d'effort que ce qui est actuellement requis de la part d'un pilote désirant placer son scooter sur béquille centrale, et d'autre part procurent au pilote une sensation réelle de confort à basse vitesse avant l'arrêt et a l'arrêt lorsqu'il n'a plus à poser les pieds sur le sol pour se maintenir en équilibre .An important characteristic of the stabilization device according to the invention lies in the fact that its implementation has the effect of occasionally lifting the chassis of the scooter from its normal position of use. These situations of occasional lifting on the one hand allow to place a scooter on αes crutches much less effort than what is currently required from a pilot wishing to place his scooter on a center stand, and on the other hand provide the pilot with a real feeling of comfort at low speed before stopping and when stopping when he no longer has to put your feet on the ground to keep your balance.
Lorsque le scooter est à l'arrêt en l'absence du pilote, frein de sécurité activé, le châssis est en position haute stabilisée Hs, en référence à la figure 5, avec des béquilles en position basse qui peuvent d'ailleurs être légèrement inclinées vers l'avant. Un mécanisme de verrouillage des béquilles en position de stabilisation peut éventuellement être activé.When the scooter is stopped in the absence of the driver, safety brake activated, the chassis is in the high stabilized position Hs, with reference to Figure 5, with crutches in the low position which can also be slightly inclined forward. A mechanism for locking the crutches in the stabilization position can optionally be activated.
L'installation du pilote sur la selle du scooter a pour effet d'abaisser légèrement l'assiette du scooter.Installing the pilot on the scooter seat has the effect of slightly lowering the trim of the scooter.
Le scooter démarre et l'augmentation de sa vitesse, combinée aux frottements des surfaces des roulettes sur le sol, a pour effet de provoquer la rotation des béquilles autour de l'axe de liaison et notamment le repassage des béquilles par la position verticale, ce qui a pour effet de soulever légèrement le châssis du scooter et son passager en assiette haute Hs .The scooter starts and the increase in its speed, combined with the friction of the surfaces of the rollers on the ground, has the effect of causing the crutches to rotate around the connecting axis and in particular the ironing of the crutches by the vertical position, this which has the effect of slightly lifting the chassis of the scooter and its passenger in a high attitude Hs.
Le basculement des béquilles s'opère alors et le pilote exerce par le seul poids de ces pieds une pression en avant sur la barre de commande de telle façon que les béquilles se trouvent complètement escamotées. L'assiette Bc du scooter est à ce stade minimale, du fait du poids du pilote qui est totalement supporté sans assistance des béquilles . En phase de ralentissement et de décélération, le pilote libère la barre de commande, ce qui rend possible la descente des béquilles par gravite, l'entrée en contact des roulettes avec le sol et le basculement du dispositif de stabilisation.The tilting of the crutches then takes place and the pilot exerts by the sole weight of these feet a pressure forward on the control bar so that the crutches are completely retracted. The scooter trim Bc is at this stage minimal, due to the weight of the pilot who is fully supported without assistance from the crutches. During the deceleration and deceleration phase, the pilot releases the control bar, which makes it possible to lower the crutches by gravity, to enter contact of the rollers with the ground and tilting of the stabilization device.
Une pression exercée vers l'arrière par les pieds du pilote sur la barre de commande provoque alors le soulèvement du châssis du scooter avec son passagerA pressure exerted backwards by the feet of the pilot on the control bar then causes the lifting of the chassis of the scooter with its passenger
(assiette haute Hs) au moment du passage des béquilles en position verticale, puis en position inclinée correspondant à une assiette basse Bs, jusqu'à une position d'arrêt avec retour à l'assiette haute stabilisée Hs .(high attitude Hs) when the crutches pass into a vertical position, then in an inclined position corresponding to a low attitude Bs, to a stop position with return to the stabilized high attitude Hs.
Il est à noter qu'en position d'arrêt "parking" avec les béquilles en position basse et l'une des roues du scooter bloquée, seule l'une des deux roulettes est à un instant donné en contact avec le sol, ce qui cependant n'affecte pas la stabilité d'ensemble du scooter.It should be noted that in the "parking" stop position with the crutches in the low position and one of the scooter wheels locked, only one of the two casters is at any given time in contact with the ground, which however does not affect the overall stability of the scooter.
Bien sûr, l'invention n'est pas limitée aux exemples qui viennent d'être décrits et de nombreux aménagements peuvent être apportés à ces exemples sans sortir du cadre de l'invention. Le dispositif de stabilisation selon l'invention peut soit équiper des scooters neufs, soit être installé sur des scooters existants. Of course, the invention is not limited to the examples which have just been described and numerous modifications can be made to these examples without departing from the scope of the invention. The stabilization device according to the invention can either be fitted to new scooters, or be installed on existing scooters.
