Abstract

The invention concerns both the production and use of removable anti-slip motor vehicle accessories. Anti-slip means linked and/or connected by chain (5) (6) (7) (9) (10) (11) (55) (70) (71) (72) (73) (74) (75) (76) (77) vary between a plurality of configurations at the periphery of a tyre (2) according to two counteracting forces. One of said forces is due to the resistance of said means to the reversible deformation (75) (76) (77) of same, or to that of an associated element (10) (70), and the other to that of a straight spring (18) or coiled spring (32) inside a substantially annular coaxial chamber (13) of the tyre. A tensioning cable (12) passes from one face of the tyre to the other via internal conduits (8) and external conduits (14) having bars (7) crossing the tread, forming two main symmetrical loops A and B, linking the anti-slip means to the chamber (13), enabling the device to be clamped to the rear face of the tyre by acting only on the front face of same. During fitting onto the tyre, the device (1) is contracted and is extended by pulling a tensioning cable (12) which is tensioned by a mechanism actuated manually (21) (22) (23) (33) (34) (35) (42) (43) (64) (79), or automatically (37) (38) (39) (40) (41 ) (65) (66) (67) (68) (69), so as to bear on the ground at the limits of the support polygon (4) of the tyre (2).

Description

Dispositifs amovibles couvrant et découvrant automatiquement un pneumatique par des moyens antidérapants.  Removable devices automatically covering and uncovering a tire by non-slip means.
L'invention concerne les accessoires automobiles amovibles montés sur les pneumatiques pour permettre aux automobilistes de rouler en sécurité sur des surfaces enneigées ou verglacées et leurs procédés de réalisation et de montage. The invention relates to removable automotive accessories mounted on tires to enable motorists to ride safely on snowy or icy surfaces and their methods of production and assembly.
Dans des conditions hivernales, pour se déplacer l'automobiliste n'a d'autre recours que celui d'équiper son véhicule de façon à éviter de patiner sur un sol enneigé ou verglacé. Dans ces conditions, actuellement, il a le choix entre deux possibilités : La première est de remplacer ses pneumatiques usuels et destinés aux conditions de circulation sur route sèche, par des pneumatiques dits " thermogomme " ou " neige ", conçus pour une circulation sur route enneigée, lesquels trouvent souvent des conditions de circulation dans lesquelles leur capacité d'accrochage est notoirement insuffisante. In winter conditions, to move the motorist has no other recourse than to equip his vehicle so as to avoid skating on snowy or icy ground. Under these conditions, at present, it has the choice between two possibilities: The first is to replace its usual tires and intended for the conditions of circulation on dry road, by tires known as "thermogomme" or "snow", designed for a road circulation snow, which often find traffic conditions in which their ability to hang is notoriously insufficient.
L'autre possibilité est d'équiper ses pneumatiques d'accessoires destinés à améliorer leur accroche dans de telles conditions. Ces accessoires, ou équipements, sont principalement de deux types : les chaînes à neige et les chaussettes textiles. The other possibility is to equip its tires accessories to improve their grip in such conditions. These accessories, or equipment, are mainly of two types: snow chains and textile socks.
Là encore, force est de constater que ces solutions ne sont pas idéales. Again, it is clear that these solutions are not ideal.
Les chaînes à neige demandent un montage plus ou moins long et laborieux, auquel même les professionnels de la route, y compris ceux dont le métier est de rouler dans les conditions les plus dures qui soient, comme sur les routes de glace tracées sur les lacs gelés près du cercle arctique, renoncent souvent, alors que leur sécurité, et même leur vie, est en jeu.  Snow chains require a more or less long and laborious assembly, to which even the professionals of the road, including those whose job is to ride in the harshest conditions, as on the ice roads drawn on the lakes frozen near the Arctic Circle, often give up, while their safety, and even their lives, is at stake.
Les chaussettes textiles ne sont pas exemptes d'inconvénients et il est assez rare que les automobilistes les apprécient. Parce que leur montage n'est pas des plus faciles, qu'elles ont une efficacité toute relative et qu'elles se dégradent rapidement. Textile socks are not without drawbacks and it is quite rare for motorists to appreciate them. Because their editing is not easy, they have a relative efficiency and they degrade quickly.
C'est ainsi que dans la plupart des pays du monde, chaque année, en hiver, les mêmes situations se répètent. Thus in most countries of the world, every year, in winter, the same situations are repeated.
Immanquablement, l'actualité fait état de longues files de véhicules immobilisés sur les routes et les autoroutes, dans un froid glacial, avec des occupants en réel péril, et ce n'est pas pour rien qu'on les appelle des " naufragés de la route ". Inevitably, news reports long lines of vehicles immobilized on roads and highways, in a freezing cold, with occupants in real danger, and it is not for nothing that they are called "castaways of the road ".
Les autobus et les ambulances elles-mêmes sont incapables de circuler, avec les conséquences que l'on imagine. Buses and ambulances themselves are unable to move, with the consequences we imagine.
Les véhicules patinent, dérapent, provoquent des accidents en cascade, des carambolages, et parfois, hélas, ils sont mortels. Les camions se mettent en travers, causant des bouchons, interdisant la circulation, y compris des engins de déneigement. L'organisation à flux tendus de l'industrie et du commerce fait que les conséquences économiques sont désastreuses. Vehicles skate, skid, cause cascading accidents, pilots, and sometimes, alas, they are deadly. Trucks get in the way, causing traffic jams, prohibiting traffic, including snow removal equipment. The just-in-time organization of industry and commerce means that the economic consequences are disastrous.
Les grandes surfaces ne sont plus approvisionnées, les usines n'ont plus les pièces détachées dont elles ont besoin pour fonctionner et des périodes de chômage technique s'ensuivent. Large supermarkets are no longer supplied, factories no longer have the spare parts they need to function and periods of technical unemployment ensue.
Et la facture est lourde... on estime le manque à gagner, au niveau national, à quatre cent millions d'euros par jour. And the bill is heavy ... it is estimated the shortfall, at the national level, four hundred million euros per day.
Personne ne peut nier que dans un monde qui se modernise de la façon que l'on sait, si, malgré tout ce qui précède, ces situations dramatiques se répètent chaque année, c'est, qu'à ce jour, aucune solution satisfaisante n'a été trouvée.  No one can deny that in a world that is modernizing in the way we know, if, despite all the above, these dramatic situations are repeated every year, it is, that to date, no satisfactory solution exists. 'has been found.
L'art antérieur fait état de très nombreux dispositifs à vocation anti-patinage ou antidérapante. The prior art mentions a large number of anti-skid or anti-slip devices.
Beaucoup sont intégrés aux pneumatiques, comme des clous ou des crampons, fixés de multiples façons. Many are integrated with tires, such as nails or crampons, fixed in multiple ways.
D'autres concernent des améliorations des dispositifs connus déjà cités, comme les chaînes ou les chaussettes, soit dans leur conception, soit dans leur technique de montage. Others relate to improvements of known devices already mentioned, such as chains or socks, either in their design or in their mounting technique.
Tous ces dispositifs requièrent un montage en, au moins, deux temps et nécessitent des outils de serrage.  All these devices require assembly in, at least, two times and require clamping tools.
. Le premier consiste à placer le dispositif sur le pneumatique en agissant sur ses moyens de fixation, à la fois, sur la face avant du pneumatique, côté route, et sur sa face arrière, côté essieu, avec des difficultés d'accès, d'autant que, pour des rai- sons liées autant à l'esthétique qu'à l'aérodynamisme, les automobiles ont des passages de roues de plus en plus étroits. . Le second consiste à déplacer son véhicule, soit en le poussant, soit en le mettant en marche, pour achever le montage et le serrage du dispositif sur le pneumatique. . The first is to place the device on the tire by acting on its fastening means, both on the front face of the tire, on the road side, and on its rear face, axle side, with access difficulties, as far as aesthetic and aerodynamic reasons are concerned, automobiles have ever narrower wheel arches. . The second is to move his vehicle, either by pushing or turning on, to complete the mounting and tightening of the device on the tire.
Aucun de ces dispositifs n'est exempt d'inconvénients souvent jugés comme rédhibitoires par la plupart des automobilistes. C'est ce qui explique pourquoi les situations désastreuses et mêmes tragiques décrites plus avant se répètent chaque année. Aucun de ces dispositifs ne relève de la technique de l'invention et aucun n'apporte une solution de nature à modifier l'attitude négative de l'automobiliste vis à vis des accessoires de ce type, pour les raisons déjà évoquées. L'invention a pour but de modifier cette attitude et ceci pour tous les utilisateurs potentiels, en premier, les automobilistes, mais aussi les chauffeurs de car, notamment scolaires ou de tourisme, les camionneurs, les conducteurs d'engins... None of these devices are free of inconveniences often considered as prohibitive by most motorists. This explains why the disastrous and even tragic situations described above are repeated every year. None of these devices comes under the technique of the invention and none provides a solution likely to change the negative attitude of the motorist with respect to accessories of this type, for the reasons already mentioned. The invention aims to change this attitude and this for all potential users, first, motorists, but also bus drivers, including school or tourism, truck drivers, machine operators ...
La technique selon l'invention utilise, au moins, un élément antidérapant relié à, ou intégrant, ou constituant lui-même, un élément déformable de façon réversible de façon calibrée, l'ensemble étant appuyé sur tout ou partie de la bande de roulement et des flancs d'un pneumatique et constituant un dispositif à géométrie variable s'auto-stabilisant sur toute la périphérie dudit pneumatique sous la traction, d'au moins, un câble tenseur, le recouvrant ou le découvrant automatiquement, selon l'action de deux forces antagonistes dont l'une est générée par l'ensemble pré-cité.

L'invention permet aussi, en agissant sur son ou ses câbles tenseurs uniquement sur la face avant du pneumatique, côté route, d'avoir une action simultanée sur sa face arrière, côté essieu. La technique de l'invention, permet à son utilisateur, après qu'il ait positionné son accessoire automobile antidérapant sur la bande de roulement de son pneumatique, un montage quasi-instantané si son accessoire est à serrage manuel, et instantané et automatique si ce dernier est à serrage motorisé et télécommandé.  The invention also makes it possible, by acting on its tensioning cable or cables only on the front face of the tire, on the road side, to have a simultaneous action on its rear face, on the axle side. The technique of the invention, allows its user, after he has positioned his non-slip automotive accessory on the tread of his tire, an almost instantaneous mounting if his accessory is manually tightened, and instantaneous and automatic if last is motorized and remote controlled.
Ainsi, l'utilisateur, et, surtout, l'utilisatrice, opère une pose de son accessoire antidérapant, mais aussi une dépose, simple, rapide, intuitive et sans avoir à consulter quelque mode d'emploi que ce soit et, de plus, sans aucun risque de se salir.  Thus, the user, and, above all, the user, operates a pose of his non-slip accessory, but also a removal, simple, fast, intuitive and without having to consult any instructions for use and, moreover, without any risk of getting dirty.
L'invention, selon ses différentes techniques de mise en œuvre, convient aux différents moyens d'antipatinage existants. Par exemple, elle convient aux chaînes antidérapantes métalliques, ou d'un autre matériau, comme aux maillages ou aux tissages de même fonction. The invention, according to its various implementation techniques, is suitable for the various existing traction control means.

Le dispositif selon la technique de l'invention est totalement déformable de façon réversible, et/ou comporte, au moins, un tel élément absorbant de l'énergie mécanique proportionnellement à une force appliquée, et permet de conférer à ses moyens antipatinants, quels qu'ils soient, une géométrie variable entre plusieurs configurations, caractérisant le concept de l'invention : .

The third is said extended and corresponds to that the device automatically takes over the entire periphery of the tire when the vehicle starts and that its anti-slip means are immobilized in the manner to be described.
Pour un dispositif à chaînes métalliques antidérapantes, ces dernières sont reliées par des anneaux, crénelés et spécifiques, à la fois, entre elles, à des barrettes stabilisatrices rigides et à un élément déformable de façon réversible absorbant de l'énergie, comme des boucles en matériau élastique renforcé, quel qu'il soit, et aussi celui le renforçant, par exemple, du type du kevlar. Ces boucles sont aussi protégées de l'écrasement, par exemple, par des bagues co-axiales de section préférentiellement carrée, reliées latéralement, ou non, entre elles, et qui se centrent automatiquement sur les boucles au cours de leur allongement. Selon les dispositifs, ces éléments déformables sont des lames métalliques, en ressorts, droites, hélicoïdales ou spiralées. For a device with anti-slip metal chains, the latter are connected by rings, crenelated and specific, at the same time, to each other, to rigid stabilizing bars and to a reversibly deformable element that absorbs energy, such as buckles. reinforced elastic material, whatever it is, and also that reinforcing it, for example, the type of Kevlar. These loops are also protected from being crushed, for example by coaxial rings of preferentially square section, connected laterally or otherwise between them, and which automatically center on the loops during their elongation. According to the devices, these deformable elements are metal blades, springs, straight, helical or spiral.
Ses barrettes stabilisatrices sont sensiblement trapézoïdales et préférablement munies de reliefs participant à l'antipatinage. Elles sont traversées de part en part par un conduit souple et de résistance appropriée, et/ou prolongées de part et d'autre par un tel élément à l'aide de bagues latérales intermédiaires, lequel s'appuie sur le flanc du pneumatique en épousant sa forme. A intervalle régulier, ces ensembles " barrette-conduit " ainsi formés sont positionnés à cheval sur la bande de roulement du pneumatique pour constituer, sous la traction des câbles tenseurs, autant d'arceaux de maintien à géométrie variable, aptes à s'adapter à des pneumatiques de dimensions voisines. Its stabilizer bars are substantially trapezoidal and preferably provided with reliefs participating in traction control. They are traversed from one side by a flexible conduit and of appropriate strength, and / or extended on either side by such an element by means of intermediate lateral rings, which rests on the sidewall of the tire while marrying its shape. At regular intervals, these "barrette-conduit" assemblies thus formed are positioned astride the tread of the tire to constitute, under tensile tensor cables, as many holding arches with variable geometry, able to adapt to tires of similar dimensions.
Ces conduits souples comportent des moyens de rétention et/ou de conduite des câbles tenseurs, comme des œillets, des roulements ou des poulies, permettant audit câble tenseur, à la fois, de relier les ensembles " barrette-conduit " décrits les uns aux autres et de les appuyer contre la bande de roulement et les flancs du pneumatique en assurant le maintien de l'ensemble de l'accessoire automobile amovible sur ce dernier. Ces poulies sont solidaires des conduits souples par des bagues concentriques et mobiles rotativement, afin de permettre à leurs axes de prendre la direction perpendiculaire à celle de la traction exercée par les câbles qui les traversent, ces derniers étant non extensibles et de résistance appropriée, en acier ou synthétique, ou composite du type du kevlar ou du carbone, et contenus dans une gaine présentant, d'une façon quelconque, un faible coefficient de frottement. These flexible ducts comprise means for retaining and / or driving tensor cables, such as grommets, bearings or pulleys, enabling said tensor cable to connect the "bar-duct" assemblies described to each other at the same time. and press them against the tread and the sidewalls of the tire by maintaining the entire removable automobile accessory on the latter. These pulleys are secured to the flexible ducts by concentric rings and rotatively movable, to allow their axes to take the direction perpendicular to that of the traction exerted by the cables through them, the latter being non-extensible and of appropriate strength, in steel or synthetic, or composite of the Kevlar or carbon type, and contained in a sheath having, in some way, a low coefficient of friction.
Ces câbles sont mis en tension par un système tenseur contenu avec ses organes fonctionnels annexes dans une enceinte sensiblement annulaire et co-axiale du pneumatique, dans laquelle ils pénètrent par l'intermédiaire d'oeillets de sa périphérie pour s'appuyer sur des roulements du type des poulies qui les maintiennent lors de leurs trajets internes. These cables are tensioned by a tensor system contained with its ancillary functional members in a substantially annular and coaxial chamber of the tire, into which they penetrate through eyelets of its periphery to rely on bearings of the type of pulleys that hold them during their internal journeys.
Selon leurs positions et leur fonctions dans le dispositif, certains des ensembles " barrette-conduit ", ou arceaux de maintien, sont traversés par les câbles tenseurs en leur permettant de passer d'une face du pneumatique à l'autre tandis que d'autres ensembles " barrette-conduit " sont tirés vers le centre du dispositif et de la roue par les mêmes câbles. Depending on their positions and their functions in the device, some of the "barrette-conduit" assemblies, or holding arches, are traversed by the tensor cables allowing them to pass from one face of the tire to the other while others "barrette-conduit" assemblies are pulled towards the center of the device and the wheel by the same cables.
Dans l'une des réalisations d'un accessoire automobile selon l'invention, les câbles tenseurs forment deux boucles symétriques principales, A et B, formant chacune une boucle secondaire, a et b, à l'intérieur de l'enceinte centrale, chacune d'elles étant appuyée sur un curseur mobile dans une gorge ou sur un rail solidaire de la base de l'enceinte. In one of the embodiments of an automotive accessory according to the invention, the tensor cables form two main symmetrical loops, A and B, each forming a secondary loop, a and b, inside the central chamber, each of them being supported on a movable cursor in a groove or on a rail secured to the base of the enclosure.
Ces curseurs, qui ont aussi un rôle de poulies, sont appuyés symétriquement sur un même ressort de compression de force supérieure à celle antagoniste opposée par la déformation des éléments antidérapants ou des éléments qui leurs sont adjoints. These sliders, which also act as pulleys, are supported symmetrically on the same compression spring force greater than the opposing antagonist by the deformation of the non-slip elements or elements that are associated with them.
Lors de la mise en tension des câbles, les boucles secondaires a et b sont déformées en comprimant proportionnellement le ressort sur lequel elles s'appuient et cette traction met le dispositif en configuration intermédiaire, dans laquelle les barrettes des extrémités sont en appui au sol aux limites avant et arrière du polygone de sustentation du pneumatique et, en poursuivant la traction des câbles alors que les barrettes sont immobilisées, le ressort se déforme en accumulant une énergie mécanique. Dès la libération du polygone de sustentation initial du pneumatique, le ressort se détend et l'énergie qu'il restitue précipite les barrettes des extrémités l'une contre l'autre, en conférant aux moyens d'antipatinage articulés leur configuration extensée. Dans une autre version du dispositif, les boucles a et b sont reliées entre elles par deux poulies solidaires d'un même ressort que la mise en tension des câbles étire en accumulant la même énergie, restituée de la même façon. During the tensioning of the cables, the secondary loops a and b are deformed by compressing proportionally the spring on which they rest and this traction puts the device in intermediate configuration, in which the end bars are in contact with the ground at the front and rear limits of the tire lift polygon and, by continuing traction of the cables while the bars are immobilized, the spring deforms by accumulating mechanical energy. As soon as the initial lifting polygon of the tire is released, the spring relaxes and the energy that it restores precipitates the bars of the extremities one against the other, conferring on the articulated anti-slip means their extended configuration. In another version of the device, the loops a and b are interconnected by two integral pulleys of the same spring as the tensioning of the cables stretches by accumulating the same energy, restored in the same way.
Dans un des dispositifs décrits, la mise en tension des câbles consiste à assembler deux poignées, chacune tenant un câble formant l'une des boucles principales A et B. In one of the devices described, the tensioning of the cables consists in assembling two handles, each holding a cable forming one of the main loops A and B.
Selon les réalisations, cette opération est manuelle ou réalisée de façon automatisée par un moteur électrique télécommandé alimenté par une source d'énergie appropriée, jusqu'à ce que le mécanisme d'assemblage des poignées, s'enclenche.  According to the embodiments, this operation is manual or automated by a remote-controlled electric motor powered by a suitable power source, until the assembly mechanism of the handles, engages.
Ce mécanisme est, par exemple, du type des verrous, les poignées dites " A " et " B " comportant chacune un élément de rétention complémentaire de l'autre, par exemple, la poignée de la boucle " A " ayant un rôle de pêne, et la poignée de la boucle " B ", comportant une ouverture ou un logement de forme complémentaire, ayant un rôle de gâche. This mechanism is, for example, the type of locks, the handles called "A" and "B" each having a retention element complementary to the other, for example, the handle of the loop "A" having a role of bolt , and the handle of the loop "B", having an opening or a housing of complementary shape, having a role of striker.
La rétention s'effectue alors par l'appui total ou partiel de l'une des parois du pêne sur l'une des parois fixes de la gâche. Par exemple, le pêne comporte, au moins, une partie articulée et poussée vers l'extérieur par un ressort de torsion et comporte des bras appuyés sur un poussoir d'extrémité sphérique les basculant dans l'autre sens, actionné manuellement, par une préhension externe, ou automatiquement par un mécanisme électrique déclenché à distance par un moyen quelconque. Le déséquilibre des forces antagonistes confère à l'ensemble du dispositif la configuration intermédiaire décrite, et met les barrettes des extrémités en appui au sol en accumulant l'énergie dans le ressort de la façon décrite plus haut.  The retention then takes place by the total or partial support of one of the walls of the bolt on one of the fixed walls of the striker. For example, the bolt comprises, at least, a hinged portion and pushed outwardly by a torsion spring and has arms supported on a spherical end plunger rocking them in the opposite direction, manually actuated by a gripping external, or automatically by an electrical mechanism triggered remotely by any means. The imbalance of the opposing forces gives the entire device the intermediate configuration described, and puts the bars of the ends in support of the ground by accumulating energy in the spring as described above.
Ces barrettes ont une forme étudiée pour qu'elles s'encastrent l'une dans l'autre en ceinturant complètement le pneumatique. These bars have a form designed so that they fit into one another by completely surrounding the tire.
Par exemple, l'une sensiblement concave et l'autre sensiblement convexe, s'auto-centrant l'une l'autre lors de leur rencontre.For example, one substantially concave and the other substantially convex, self-centering each other during their meeting.
La dépose d'un tel accessoire automobile s'effectue en annulant la tension de ses câbles tenseurs d'une façon quelconque. Dans le dispositif décrit, celle-ci consiste à séparer les poignées et cette opération est, selon les réalisations, soit manuelle, par exemple, par poussée sur le poussoir externe décrit, soit automatiquement par le mécanisme électrique déclenché à distance, actionnant ce même élément, par exemple, par un électro-aimant, ou en mettant en rotation, par un micro-moteur électrique adapté, une roue dentée engrenée à une crémaillère solidaire du poussoir. Cette dernière réalisation permet à son utilisateur de déclencher le processus de dépose du dispositif depuis son poste de conduite, un peu avant de s'arrêter, d'attendre qu'il reprenne sa configuration contractée permettant à ses pneumatiques de reprendre contact avec le sol, à la suite de quoi il ne lui reste plus qu'à descendre de son véhicule et à le retirer. The removal of such an automobile accessory is effected by canceling the tension of its tensioning cables in any way. In the device described, it consists in separating the handles and this operation is, depending on the embodiments, either manual, for example, by pushing on the external pusher described, or automatically by the remotely triggered electric mechanism, actuating this same element. for example, by an electromagnet, or by rotating, by a suitable electric micro-motor, a toothed wheel geared to a rack integral with the pusher. This last embodiment allows the user to trigger the process of removing the device from his driving position, a little before stopping, waiting for it to resume its contracted configuration allowing his tires to reconnect with the ground, after which he only has to get out of his vehicle and remove it.
Un autre dispositif selon l'invention, préférentiel, permet de serrer ses deux câbles tenseurs en les croisant symétriquement l'un par rapport à l'autre et par rapport à l'axe vertical du dispositif et du pneumatique vu de face, cette situation renforçant l'appui l'une sur l'autre des barrettes des extrémités lorsque la chaîne est en configuration extensée et ceinture le pneumatique. Another device according to the invention, which is preferred, makes it possible to tighten its two tensor cables by crossing them symmetrically with respect to each other and with respect to the vertical axis of the device and the tire seen from the front, this situation reinforcing the support of one of the other end bars when the chain is in extended configuration and belt the tire.
Dans celui-ci, après leur retour sur la face avant du pneumatique, chacun des câbles est appuyé sur une poulie située du côté opposé à la boucle qu'il forme, puis fixé symétriquement sur un tambour d'axe à roulement libre, par exemple sur un chemin de roulement, à billes ou à rouleaux co-axial de celui d'une roue dentée et/ou d'une roue à rochet, à cliquet sur ressort de torsion. Ce cliquet est débrayable d'une façon quelconque, par exemple, par un poussoir ou une came rotative en appui sur lui, actionnée, soit, manuellement, par une molette externe, soit, de façon automatisée par un des mécanismes décrits. In this, after their return to the front face of the tire, each of the cables is pressed on a pulley located on the opposite side of the loop that it forms, then symmetrically fixed on a free-rolling pin drum, for example on a raceway, ball or roller coaxial with that of a toothed wheel and / or a ratchet wheel, ratchet torsion spring. This pawl is disengageable in any way, for example, by a pusher or a rotating cam bears on it, actuated, either manually by an outer wheel, or automatically by one of the mechanisms described.
La roue est reliée au tambour par un élément lui transmettant son couple et constituant le système tenseur du câble, comme un ressort de torsion hélicoïdal ou spiralé, dont l'une des extrémités est solidaire de l'arbre de la roue et l'autre du tambour. The wheel is connected to the drum by an element transmitting its torque and constituting the tensor system of the cable, such as a helical or spiral torsion spring, one end of which is secured to the wheel shaft and the other to the wheel. drum.
La mise en rotation de cette roue dentée s'effectue, soit manuellement, par une manivelle ou une clé à cliquet adaptée, soit de façon automatisée par un mécanisme dédié contenu dans l'enceinte centrale avec sa source d'énergie. The rotation of this gear is effected, either manually by a crank or a ratchet adapted, or automatically by a dedicated mechanism contained in the central chamber with its power source.
Manuellement, son entraînement est assuré, par exemple, par un bras pivotant solidaire du dispositif, monté sur l'axe de la roue dentée et ayant un rôle de manivelle ou de clé à cliquet, ce bras étant aussi mobile horizontalement, soit, par glissement sur son axe, soit, par solidarisation à un axe télescopique ou rétractable, soit, par des filetages de son moyeu et de son axe, étudiés pour qu'une rotation le déplace simultanément horizontalement selon son sens de rotation.  Manually, its drive is ensured, for example, by a pivoting arm integral with the device, mounted on the axis of the toothed wheel and having a role of crank or ratchet, this arm being also movable horizontally or by sliding on its axis, either by securing to a telescopic or retractable axis, or by threads of its hub and its axis, studied so that a rotation simultaneously moves horizontally according to its direction of rotation.
Ceci pour lui permettre de prendre, au moins, deux positions relativement à l'enceinte centrale, en avant et libre de pivoter en entraînant la roue dentée et/ou la roue à rochet, selon le dispositif, et en arrière, contre l'enceinte ou dans un logement dédié. This to enable it to take, at least, two positions relative to the central speaker, forward and free to rotate by driving the toothed wheel and / or the ratchet wheel, depending on the device, and back against the speaker or in a dedicated housing.
Selon le cas, ce bras comporte une partie coulissante allongeant son bras de levier en augmentant sa force de serrage. Sa manœuvre s'effectue, par exemple, par, au moins, une poignée basculable montée sur une platine rotative et désaxée par rapport à l'axe vertical du bras, lui conférant, lorsqu'il est avancé sur son axe, sa fonction de manivelle et/ou de clé à cliquet. Par les mouvements rotatifs de va et vient du bras pivotant, les câbles tenseurs s'enroulent en tirant symétriquement sur la chaîne d'éléments antidérapants et déformables jusqu'à ce que les barrettes des extrémités viennent en appui au sol. Depending on the case, this arm has a sliding portion extending its lever arm by increasing its clamping force. Its maneuver is performed, for example, by at least one tiltable handle mounted on a turntable and offset relative to the vertical axis of the arm, conferring, when advanced on its axis, its crank function and / or ratchet. By the rotary movements back and forth of the pivoting arm, the tensor cables are wound by pulling symmetrically on the chain of non-slip and deformable elements until the bars of the ends bear against the ground.
En continuant la mise en rotation de la roue dentée alors que les barrettes sont immobilisées, tel que déjà dit, le ressort se déforme en accumulant l'énergie mécanique qu'il restituera instantanément au démarrage du véhicule en projetant les barrettes des extrémités de la chaîne l'une contre l'autre. By continuing the rotation of the toothed wheel while the bars are immobilized, as already said, the spring is deformed by accumulating the mechanical energy it will return instantly when starting the vehicle by projecting the bars of the ends of the chain one against the other.
Selon la réalisation du dispositif, un mécanisme connu d'inversion du sens d'entraînement de ce bras est adjoint, quel qu'il soit, afin de convenir aux utilisateurs gauchers. According to the embodiment of the device, a known mechanism for reversing the drive direction of this arm is added, whatever it is, to suit left-handed users.
De même, par une fonction dynamométrique connue, elle aussi adjointe, il permet un couple de serrage optimum des câbles tenseurs qui est signalé visuellement, ou non, par exemple, par une diode ou un led.  Similarly, by a known dynamometric function, also adjoined, it allows an optimum tightening torque of the tensor cables which is visually indicated, or not, for example, by a diode or a led.
Une fois le serrage effectué, le bras reprend sa position, par exemple, dans un logement où il est immobilisé par le bascule- ment et l'insertion de sa poignée dans l'une des parois dudit logement, sa libération s'effectuant en redressant sa poignée.  Once the tightening is completed, the arm resumes its position, for example, in a housing where it is immobilized by the tilting and the insertion of its handle into one of the walls of said housing, its release being effected by straightening his handle.
En reprenant les spécificités du dispositif précédent, un autre dispositif permet de serrer les câbles tenseurs en les croisant. Il consiste, après leur retour sur la face avant du pneumatique, à solidariser chacun d'eux aux extrémités du bras pivotant en les passant à travers des œillets ou des anneaux solidaires du bras avant de les solidariser au tambour par des œillets ou des attaches symétriques, la mise en tension permettant de les croiser consistant à faire faire une demi-rotation au bras. By taking again the specificities of the preceding device, another device makes it possible to tighten the tensioning cables by crossing them. It consists, after their return on the front face of the tire, to secure each of them to the ends of the pivoting arm by passing them through eyelets or rings integral with the arm before attaching them to the drum by eyelets or symmetrical fasteners. , the tensioning to cross them consisting of making a half-rotation arm.
Son système tenseur est constitué, soit par le dispositif décrit, reliant la roue dentée au tambour par un ressort de torsion, soit constitué par deux ressorts, par exemple, de type cylindrique et de traction, chacun d'eux étant solidaire de l'un des câbles et chacun étant fixé latéralement au dessus du bras pivotant, par exemple, par des pitons solidaires de l'enceinte centrale. Dans des dispositifs à serrage motorisé et automatisé, la demi-rotation du bras est effectuée par le mécanisme dédié. Its tensioning system is constituted either by the device described, connecting the toothed wheel to the drum by a torsion spring, or consists of two springs, for example, cylindrical type and traction, each of them being integral with one cables and each being fixed laterally above the pivoting arm, for example, by pegs integral with the central chamber. In motorized and automated clamping devices, the half rotation of the arm is performed by the dedicated mechanism.
Par exemple, par une télécommande et/ou un déclencheur à distance, agissant, par exemple, sur, au moins, un engrenage solidaire de l'axe du bras et/ou de la roue dentée, et engagé dans une crémaillère et/ou à une transmission adaptée. For example, by a remote control and / or a remote release, acting, for example, on at least one gear integral with the axis of the arm and / or the toothed wheel, and engaged in a rack and / or a suitable transmission.
Leur dépose s'effectue de la même façon, par le débrayage du cliquet par rotation de la came l'écartant de ladite roue dentée. Selon sa conception, l'enceinte annulaire de l'accessoire automobile comporte, ou non, des poignées facilitant sa manipulation et est, par exemple, réalisée en deux parties assemblables dans des conditions d'étanchéïté. Their removal is carried out in the same way, by disengaging the pawl by rotating the cam away from said toothed wheel. According to its design, the annular enclosure of the automotive accessory comprises or not handles to facilitate its handling and is, for example, made of two parts assembled in sealing conditions.
. Une partie inférieure, la base rigide et non oxydable supportant le mécanisme tenseur des câbles et leurs poulies de maintien et dont la périphérie comporte les œillets permettant leurs passages dans les mêmes conditions d'étanchéïté.  . A lower part, the rigid and non-oxidizable base supporting the tensor mechanism of the cables and their holding pulleys and whose periphery comprises the eyelets allowing their passage under the same conditions of sealing.
. Une partie supérieure en matériau non oxydable, plastique, synthétique ou autre, préférablement colorée et décorative et qui est aussi un support d'image du fabricant, avec son logo et/ou sa marque, le tout réfléchissant et/ou éclairé par des leds. Elle renferme le système tenseur et ses organes permettant son automatisation, leurs câblages, circuits et programmes informatiques aussi ceux de production et stockage d'énergie, tous éléments adaptés à la satisfaction du concept. .

L'invention inclue dans l'enceinte un mécanisme utilisant le seul mouvement du dispositif pour créer cette énergie.  The invention includes in the enclosure a mechanism using the single movement of the device to create this energy.
Par exemple, du type des dynamos inertielles où une masselotte mûe par gravité durant la rotation du dispositif relativement à, au moins, un autre élément, lui même fixe ou mobile, l'un et/ou l'autre possédant un potentiel électrique et/ou magnétique de nature à générer une énergie électrique conduite par un câblage adapté et/ou utilisée de façon induite. For example, of the type of inertial dynamos where a weight rained by gravity during the rotation of the device relative to, at least, another element, itself fixed or mobile, the one and / or the other having an electric potential and / or magnetic to generate electrical energy driven by wiring adapted and / or used in an induced manner.
Un autre mécanisme générateur d'énergie électrique utilise les vibrations du même dispositif lors de son utilisation. Another electric power generating mechanism uses the vibrations of the same device during its use.
Dans d'autres réalisations, l'énergie provient d'un système connu comme ceux permettant aux pilotes, notamment lors de compétitions sportives, de modifier la pression de leurs pneumatiques tout en roulant. In other embodiments, the energy comes from a system known as those allowing pilots, especially during sports competitions, to change the pressure of their tires while driving.
Ces différents moyens de production d'énergie électrique permettent la réalisation de dispositifs plus élaborés, amplement justifiés par les situations dramatiques citées en préambule. These different means of producing electrical energy allow the realization of more elaborate devices, amply justified by the dramatic situations mentioned in the preamble.
Par exemple, ces accessoires automobiles disposent de moyens annexes d'actions ou d'émissions participant à, ou renforçant, l'accrochage du pneumatique et de ses moyens antidérapants au sol et/ou facilitant leur usage. For example, these automotive accessories have ancillary means actions or emissions participating in, or reinforcing, the attachment of the tire and its non-slip means to the ground and / or facilitating their use.
Par exemple, mécaniques, de tension annexe des câbles, et/ou indiquant leur tension optimum, ou thermiques, comme une résistance permettant le dégivrage d'un organe du dispositif, ou lumineux, comme des diodes, des leds, des semi-conducteurs.  For example, mechanical, auxiliary voltage cables, and / or indicating their optimum voltage, or thermal, such as a resistor for defrosting a device member, or light, such as diodes, LEDs, semiconductors.
Le dispositif comporte un mécanisme spécifique de blocage automatique de la chaîne dans sa configuration extensée. The device includes a specific mechanism for automatically locking the chain in its extended configuration.
II utilise, à la fois, l'énergie cinétique dûe à la détente des ressorts du système tenseur dès que le pneumatique libère son polygone de sustentation initial, et, pour sa mise en action, celle dûe à la tension desdits câbles et le mouvement qu'elle provoque. Il est, soit interne aux barrettes des extrémités, creuses et permettant, à la fois, le passage du câble et l'insertion dudit mécanisme, soit externe et annexe en les prolongeant par une partie arrière incurvée s'appuyant sur le flanc du pneumatique. Dans des dispositifs nécessitant une stabilité supérieure, le même mécanisme annexe est aussi adopté pour leur partie avant. II comporte, au moins, un crochet rotatif sur un axe sous, à la fois, la traction exercée sur lui par, au moins, un câble tenseur et un ressort, par exemple, spiralé et co-axial, exerçant une force de rappel antagoniste à celle dûe à la traction latérale du câble. Dès la mise en tension des câbles conférant au dispositif sa configuration intermédiaire, au moins l'un d'eux bascule le crochet en position de verrouillage et lorsque les barrettes des extrémités de la chaîne sont précipitées l'une contre l'autre, ledit crochet vient percuter, et, par les courbes du dessin de sa partie avant, passer derrière et s'accrocher à un barreau perpendiculaire, solidaire de la barrette en vis à vis. It uses, at the same time, the kinetic energy due to the relaxation of the springs of the tensor system as soon as the tire releases its initial lifting polygon, and, for its activation, that due to the tension of said cables and the movement which 'she provokes. It is either internal to the ends of the bars, hollow and allowing, at the same time, the passage of the cable and the insertion of said mechanism, or external and annex extending them by a curved rear part resting on the sidewall of the tire. In devices requiring superior stability, the same attachment mechanism is also adopted for their front part. It comprises, at least, a rotary hook on an axis under, at the same time, the traction exerted on it by, at least, a tensor cable and a spring, for example, coiled and coaxial, exerting an antagonistic return force to that due to the lateral pull of the cable. As soon as the cables giving the device their intermediate configuration are tensioned, at least one of them switches the hook into the locking position and when the bars of the ends of the chain are precipitated against each other, said hook It strikes, and, by the curves of the drawing of its front part, pass behind and cling to a perpendicular bar, integral with the bar opposite.
Dès le relâchement de cette tension, son ressort spiralé rappelle le crochet dans sa position déportée en désolidarisant automatiquement les deux barrettes extrêmes, simultanément à la rétractation de la chaîne des éléments antidérapants. Dans les dispositifs munis de sources d'énergie, quelles qu'elles soient, des variantes de fonctionnement de ce mécanisme de solidarisation des barrettes des extrémités comportent un moyen électrique, comme un micro-moteur, un relais et/ou un électro-aimant, déplaçant rotativement ledit crochet autour de son axe, avec, ou sans, la traction dûe au câble tenseur. As soon as this tension is released, its spiral spring recalls the hook in its offset position by automatically disconnecting the two end bars simultaneously with the retraction of the chain of non-slip elements. In devices equipped with any energy source, variants of operation of this mechanism for joining the terminal strips include an electrical means, such as a micro-motor, a relay and / or an electromagnet, rotatably displacing said hook about its axis, with or without pulling due to the tensor cable.
Ce moyen participant aussi, d'une façon quelconque, à la solidarisation magnétique des deux barrettes et/ou de leurs boîtiers. Dans une autre variante du dispositif, l'élément déformable est, par exemple, un tissage ou un maillage réalisé dans un matériau de résistance adaptée, quel qu'il soit, intégrant, par exemple, à chaque croisement de ses mailles, des renforts, métalliques ou autres, les protégeant de l'écrasement et contribuant aussi à l'antipatinage de l'ensemble du dispositif. This means also participating, in some way, in the magnetic connection of the two bars and / or their housings. In another variant of the device, the deformable element is, for example, a weave or a mesh made of a suitable resistance material, whatever it may be, integrating, for example, at each crossing of its meshes, reinforcements, metal or other, protecting them from crushing and also contributing to the traction control of the entire device.
Ce maillage est alors solidaire, par des attaches spécifiques, de barrettes stabilisatrices de dimensions inférieures, en appui sur la bande de roulement du pneumatique et reliées aux chaînes antidérapantes par les anneaux décrits. Dans une réalisation différente du dispositif mettant en œuvre l'invention, comportant les mêmes arceaux de maintien que précédemment décrits, l'élément antipatinant est lui même une structure d'un seul tenant déformable de façon réversible, la résistance à la déformation de cette structure constituant la force antagoniste à celle du ressort du système tenseur. This mesh is then secured, by specific fasteners, stabilizer bars of smaller dimensions, bearing on the tread of the tire and connected to anti-slip chains by the rings described. In a different embodiment of the device embodying the invention, comprising the same holding arches as previously described, the antipatinant element itself is a one-piece structure reversibly deformable, the resistance to deformation of this structure constituting the force antagonistic to that of the spring of the tensor system.
Par exemple, constituée par des maillages ou des tissages, quel qu'en soit le matériau, renforcés latéralement et convexes dans les deux sens, aptes à suivre les courbes de la bande de roulement du pneumatique et celles la joignant à ses flancs. Dans les réalisations destinées aux surfaces verglacées, l'une des technologies utilise une adhérence par un effet ventouse.For example, constituted by meshes or weavings, whatever the material, laterally reinforced and convex in both directions, able to follow the curves of the tread of the tire and those joining it to its flanks. In the constructions intended for icy surfaces, one of the technologies uses an adhesion by a suction effect.
Par exemple, la surface en contact est du type des gels ou des substrats spongieux et/ou épais et déformable et comporte des cavités de paroi étanche qui se déforment et s'écrasent sous la pression du véhicule en chassant leur air. For example, the contacting surface is of the type of gels or spongy and / or thick and deformable substrates and has sealed wall cavities which deform and crush under the pressure of the vehicle while expelling their air.
Celles-ci se comportent comme des ventouses tant qu'elles sont en contact avec le sol dans leur configuration écrasée. These behave like suckers as long as they are in contact with the ground in their crushed configuration.
Pour une autre, la surface en contact utilise la technologie " bionique " provoquant l'adhérence des pattes de certains animaux, comme les geckos, leur permettant de tenir sur des parois verticales lisses. For another, the surface in contact uses the "bionic" technology causing the adhesion of the legs of certain animals, like the geckos, allowing them to hold on smooth vertical walls.
Elles sont alors constituées de multiples lamelles, de nature de surface, de plasticité, de direction et d'espacement appropriés.  They then consist of multiple slats, surface nature, plasticity, direction and spacing appropriate.
Dans une réalisation simplifiée d'un accessoire automobile relevant de la même invention et permettant aussi à ses moyens antidérapants, quels qu'ils soient, de prendre les trois configurations, contractée, intermédiaire et extensée, caractérisant son concept, le mécanisme tenseur est directement constitué par les câbles tenseurs, qui sont eux-mêmes élastiques et déforma- bles de façon réversible et calibrée. In a simplified embodiment of a car accessory of the same invention and also allowing its antiskid means, whatever they are, to take the three configurations, contracted, intermediate and extended, characterizing its concept, the tensor mechanism is directly constituted by tensor cables, which are themselves elastic and deformable in a reversible and calibrated manner.
Ceux-ci forment les boucles A et B suivant les mêmes trajets que ceux précédemment décrits, ces câbles étant mis en tension de la même façon que précédemment décrit, par les poignées assemblables, le bras pivotant ou les poulies désaxées et leurs différents moyens de mise en œuvre, préalablement décrits.  These form the loops A and B following the same paths as those described above, these cables being tensioned in the same manner as previously described, by the assembled handles, the pivoting arm or the off-axis pulleys and their different means of setting. implemented, previously described.
Les moyens antidérapants utilisés sont aptes à s'appuyer sur le revêtement d'une route non enneigée sans le dégrader, tout en assurant l'antipatinage sur une route enneigée, conformément aux normes en vigueur en ce domaine. The non-slip means used are able to rely on the coating of a non-snow-covered road without degrading it, while providing traction control on a snow-covered road, in accordance with the standards in force in this area.
Leurs surfaces en contact avec le pneumatique présentent un faible coefficient de frottement, par exemple, par des appuis de forme arrondie et/ou une enduction par un matériau anti-adhérent.  Their surfaces in contact with the tire have a low coefficient of friction, for example, by supports of rounded shape and / or a coating with a non-stick material.
La mise en œuvre du concept de l'invention permet plusieurs dispositions du, ou des, câbles tenseurs. The implementation of the concept of the invention allows several provisions of the tensor cables.
Dans l'une d'elles, un seul câble constitue les deux boucles A et B, lesquelles se rejoignent à l'intérieur de l'enceinte annulaire. Pour des raisons visant à limiter les pertes d'énergie, à la fois, par frottements et inertie, les dispositifs de mise en œuvre de l'invention utilisent deux câbles tenseurs symétriques, chacun formant, au moins, une boucle. In one of them, a single cable constitutes the two loops A and B, which meet within the annular enclosure. For reasons to limit the energy losses, both by friction and inertia, the implementation devices of the invention use two symmetrical tensor cables, each forming at least one loop.
Selon les versions, les câbles sont aussi disposés différemment, par exemple, ils se croisent sur le dessus du pneumatique. Ceux-ci forment alors, pour l'un, une demi-boucle A sur la face avant du pneumatique et une demi-boucle B sur sa face arrière, et pour l'autre, une demi-boucle B sur la face avant du pneumatique et une demi-boucle A sur sa face arrière, leur croisement se faisant dans, ou entre, des barrettes particulières des arceaux cinq et/ou six, droites et/ou de sorties inversées, ou obliques. En faisant se rejoindre les boucles à l'intérieur de l'enceinte annulaire, cette même disposition utilise un seul câble tenseur. La figure 1 décrit un dispositif comportant deux boucles principales, A et B, et ses boucles secondaires a et b, formées dans l'enceinte centrale par deux câbles tenseurs. Depending on the version, the cables are also arranged differently, for example, they intersect on the top of the tire. These then form, for one, a half-loop A on the front face of the tire and a half-loop B on its rear face, and for the other, a half-loop B on the front face of the tire and a half loop A on its rear face, their crossing being in, or between, particular bars of the arches five and / or six, straight and / or inverted or oblique outlets. By joining the loops inside the annular enclosure, this same arrangement uses a single tensor cable. FIG. 1 describes a device comprising two main loops, A and B, and its secondary loops a and b, formed in the central chamber by two tensor cables.
L'un d'eux est solidaire de l'arceau deux par une attache A' et de l'enceinte annulaire par une autre attache A", et l'autre, de l'arceau neuf par une attache B' et de la même enceinte par une autre attache B", les deux câbles n'étant pas mis en tension. Dans la première boucle, dite A, le câble tenseur est solidaire de l'arceau deux, par une rétention adaptée dite attache A', entre dans l'enceinte centrale par l'un de ses œillets, en ressort pour s'appuyer sur les roulements solidaires des arceaux trois et quatre, puis rentre à nouveau dans l'enceinte centrale pour former sa boucle secondaire, a, qui vient s'appuyer sur une poulie/ curseur mobile sur un rail ou dans une gorge et en appui sur un ressort, puis ressort de l'enceinte pour traverser l'arceau cinq et ressortir sur la face arrière du pneumatique et traverser et/ou s'appuyer sur les œillets ou les poulies solidaires des arceaux quatre, trois et deux, pour rejoindre l'arceau un, le traverser et revenir sur la face avant du pneumatique pour être fixé, par une rétention adaptée dite attache A", à l'enceinte centrale, après avoir traversé une poignée, dite " A " parce que tenant le câble correspondant, destinée à le mettre en tension.  One of them is secured to the hoop two by a fastener A 'and the annular enclosure by another fastener A ", and the other, the new hoop by a fastener B' and of the same enclosure by another fastener B ", the two cables not being tensioned. In the first loop, called A, the tensor cable is secured to the hoop two, by a suitable retention said fastener A ', enters the central chamber by one of its eyelets, comes out to rely on the Bearings secured to the three and four hoops, then enters the central chamber again to form its secondary loop, a, which comes to rest on a pulley / movable slider on a rail or in a groove and resting on a spring, then out of the enclosure to cross the arch five and out on the rear face of the tire and cross and / or rely on the eyelets or pulleys solidarity of the arches four, three and two, to join the arch one, cross it and return to the front face of the tire to be fixed, by a suitable retention said attachment A ", to the central speaker, after having passed through a handle, called" A "because holding the corresponding cable, intended to put it in tension.
Dans la seconde boucle, dite B, le câble tenseur est solidaire de l'arceau neuf, par une rétention adaptée dite attache B', suit un parcours symétrique au cours duquel il forme sa boucle secondaire, b, symétrique de la première qui vient s'appuyer sur une autre poulie mobile sur le même rail et en appui sur le même ressort avant de passer sur la face arrière à travers l'arceau six puis de revenir sur la face avant à travers celui de l'arceau dix pour être fixé par une rétention adaptée dite attache " B ", à l'enceinte centrale, symétriquement par rapport à son axe vertical, après avoir traversé une autre poignée dite " B " symétrique de celle de la première boucle. In the second loop, called B, the tensor cable is secured to the new rollbar, by a suitable retention said fastener B ', follows a symmetrical course in which it forms its secondary loop, b, symmetrical of the first that comes s press another moving pulley on the same rail and rest on the same spring before passing on the rear face through the arch six and then back on the front through that of the arch ten to be fixed by a suitable retention said fastener "B" to the central speaker, symmetrically with respect to its vertical axis, after passing through another handle called "B" symmetrical to that of the first loop.
A l'arrière du pneumatique, les arceaux cinq et six par lesquels les câbles passent d'une face à l'autre, sont reliés par un lien compensant la traction latérale dudit câble, pour leur assurer un positionnement de direction sensiblement radiale. At the rear of the tire, the arches five and six through which the cables pass from one face to the other, are connected by a link compensating the lateral traction of said cable, to ensure a position of substantially radial direction.
Les dessins montrent le dispositif dans ses différentes réalisations et configurations, l'enceinte centrale étant non recouverte par sa protection supérieure. The drawings show the device in its various embodiments and configurations, the central speaker being not covered by its upper protection.
Quand ils sont situés sur la face avant du pneumatique, côté route, les câbles sont pleins et noirs, pour la boucle "A ", et tigrés noirs et blancs, pour la boucle " B ". Ils sont en contours, quand ils sont sur la face arrière du pneumatique, côté essieu. Figure 1 : Vue de face du dispositif (1) en configuration contractée lorsqu'il vient d'être positionné autour du pneumatique (2) sur sa roue (3), reposant au sol sur son polygone de sustentation (4).  When they are located on the front side of the tire, on the road side, the cables are full and black, for the "A" loop, and black and white tabs, for the "B" loop. They are outlines, when they are on the rear side of the tire, axle side.

Les câbles (12) forment deux boucles principales, A et B, la première étant solidaire de l'arceau deux par une fixation A', et de l'enceinte centrale (13) par une autre A", et la seconde de l'arceau neuf par une fixation B' et de l'enceinte par une autre B".The cables (12) form two main loops, A and B, the first being secured to the hoop two by a fastener A ', and the central speaker (13) by another A ", and the second of the new arch by a fixation B 'and the enclosure by another B ".
Elles passent d'une face du pneumatique à l'autre à travers les conduits (8) internes aux barrettes (7). They pass from one face of the tire to the other through the conduits (8) internal to the bars (7).
Les conduits latéraux (14) sont en appui sur les flancs du pneumatique et tenus dans une direction radiale par un lien (15). The lateral ducts (14) bear against the sidewalls of the tire and are held in a radial direction by a link (15).

In the central chamber (13) each of the loops A and B, forms a secondary loop, a and b, bearing on two pulleys (16) movable on a rail (17) and bearing on the same spring (18).
