The strap has an elongated body (7) with projecting edges (6) for being supported in position on a tire, and a serrated surface (3) arranged on a tire tread of the tire opposite to a snowboard highway. A reinforced zone (8) is supported on a rim, and three dot fasteners (4) have anti-retraction bulges engaged in three consecutive holes (2) pierced in at an end of the strap.

Description

La présente invention concerne un dispositif destiné à équiper les rouesThe present invention relates to a device for equipping the wheels

des véhicules automobiles et à leur permettre d'améliorer leur adhérence sur route enneigée lors de leur rotation.  motor vehicles and to enable them to improve their grip on snow-covered roads during their rotation.

Les roues de ces véhicules sont traditionnellement équipées de systèmes généralement 5 métalliques assurant la même fonction; certains modèles font l'objet d'une mise en place mal aisée et le roulage sur route sèche est rendu difficile et sollicite des efforts sur la structure du pneumatique dans tous les cas.  The wheels of these vehicles are traditionally equipped with generally metallic systems providing the same function; some models are poorly implemented and running on dry road is difficult and requires efforts on the tire structure in all cases.

Le dispositif selon l'invention permet de pallier à ces inconvénients.  The device according to the invention overcomes these disadvantages.

Il comporte en effet selon une première caractéristique une forme allongée qu'il y a lieu 10 de passer au travers de la jante et qui vient se positionner perpendiculairement au plan vertical du pneumatique pour ensuite l'encercler avant de se voir maintenu verrouillé sur lui même par boutons pressions.  It has in fact according to a first characteristic an elongated shape that must be passed through the rim and is positioned perpendicular to the vertical plane of the tire and then encircle before being kept locked on itself by snaps.

La mise en place par l'utilisateur est extrêmement simplifiée et rapide. 11 suffira de placer plusieurs dispositifs pour équiper une roue et pour ce faire déplacer éventuellement une fois le 15 véhicule.  The implementation by the user is extremely simplified and fast. It will suffice to place several devices for equipping a wheel and possibly moving the vehicle once.

La forme quasi plate des faces du dispositif ainsi que sa nature non métallique réduisent considérablement les efforts appliqués sur la structure du pneumatique et autorisent mieux un roulage limité sur route non enneigée.  The almost flat shape of the faces of the device as well as its non-metallic nature considerably reduce the forces applied to the structure of the tire and allow better limited running on non-snow-covered road.

Selon des modes particuliers de réalisation: - La partie du dispositif placée en regard de la surface du pneumatique peut comporter des bords saillants améliorant ainsi le maintien en position désirée pendant la rotation de la roue.  According to particular embodiments: the part of the device placed opposite the surface of the tire may comprise projecting edges thus improving the retention in the desired position during the rotation of the wheel.

- La partie du dispositif placée en regard de la route enneigé peut comporter une surface crénelée pour améliorer l'adhérence à la neige.  - The part of the device placed next to the snowy road may have a crenelated surface to improve the grip on the snow.

- La zone du dispositif en appui sur la jante peut avoir une section renforcée sur une 25 longueur suffisante.  The zone of the device resting on the rim may have a reinforced section over a sufficient length.

- Le verrouillage du dispositif se fait par trois boutons pressions engagés dans trois trous consécutifs parmi ceux disponibles.  - The locking device is made by three snaps engaged in three consecutive holes among those available.

Les dessins annexés illustrent l'invention: La figure 1 représente un exemplaire du dispositif monté sur une roue vue de face.  The accompanying drawings illustrate the invention: FIG. 1 represents a copy of the device mounted on a wheel seen from the front.

La figure 2 représente un exemplaire du dispositif monté sur une roue vue en coupe, avec détail du dispositif de verrouillage.  Figure 2 shows a copy of the device mounted on a wheel in section, with detail of the locking device.

La figure 3 représente un exemplaire du dispositif en vue en plan, avec détails du crénelage et des bords saillants.  Figure 3 shows a copy of the device in plan view, with details of aliasing and protruding edges.

En référence à ces dessins, le dispositif comporte un corps en forme allongée (7) dont une zone renforcée (8) est à disposer en appui sur la jante et dont une partie crénelée (3) est à disposer sur la bande de roulement du pneumatique en regard de la route enneigée.Une extrémité (1) du dispositif est percée de trous (2) pouvant recevoir les boutons pressions (4) permettant un maintien en position désirée après avoir tendu le dispositif en tirant l'extrémité (1) tout en immobilisant l'autre extrémité constituée de la boucle (5) . Dans la forme de réalisation selon la figure 3, la partie du dispositif placée en regard de la surface du pneumatique peut comporter des bords saillants (6) améliorant le maintien en position désirée sur le pneumatique.  With reference to these drawings, the device comprises an elongate shaped body (7) of which a reinforced zone (8) is to be placed in abutment on the rim and of which a crenellated part (3) is to be disposed on the tread of the tire. next to the snowy road.One end (1) of the device is pierced with holes (2) which can receive the snaps (4) for holding in the desired position after having stretched the device by pulling the end (1) while immobilizing the other end consisting of the loop (5). In the embodiment according to Figure 3, the portion of the device placed facing the tire surface may have projecting edges (6) improving the maintenance in desired position on the tire.

La partie du dispositif placée en regard de la route enneigée comporte une surface crénelée (3) améliorant l'adhérence à la neige.  The portion of the device placed opposite the snowy road has a crenellated surface (3) improving the adhesion to the snow.

Selon la figure 2, la zone (8) du dispositif en appui sur la jante peut faire l'objet d'un renforcement de section non représenté.  According to Figure 2, the zone (8) of the device resting on the rim may be subject to a not shown section reinforcement.

Le détail du verrouillage du dispositif fait apparaître l'engagement des trois boutons pressions(4) dans les trois trous consécutifs (2) . Ce même détail montre les renflements (9) faisant office de ressorts demandant une 50 pression d'engagement importante et par là même nécessitant un effort de désengagement aussi important sécurisant le maintien en position du dispositif.  The detail of the locking device shows the engagement of the three snaps (4) in the three consecutive holes (2). This same detail shows the bulges (9) acting as springs requiring a large commitment pressure and thereby requiring such a large disengagement effort securing the holding position of the device.

Selon une variante non illustrée, le verrouillage du dispositif peut être assuré au moyen d'une boucle ou d'un système à adhérence de surfaces.  According to a variant not shown, the locking of the device can be provided by means of a loop or a surface adherence system.

A titre d'exemple non limitatif, le dispositif aura une longueur adaptée aux dimensions 55 des pneumatiques avec trois longueurs standards recoupables côté trous.La largeur sera de l'ordre de 17 millimètres et l'épaisseur de l'ordre de 5 millimètres.  By way of non-limiting example, the device will have a length adapted to the dimensions 55 of the tires with three standard lengths that can be cut on the hole side. The width will be of the order of 17 millimeters and the thickness of the order of 5 millimeters.

Le dispositif peut être réalisé en matière plastique en une seule opération de moulage par injection.  The device can be made of plastic material in a single injection molding operation.

Le dispositif selon l'invention est particulièrement destiné à équiper les roues des 60 véhicules automobiles.  The device according to the invention is particularly intended to equip the wheels of 60 motor vehicles.
