Description

Chaînes neige : L'invention présentée concerne des chaines à neige à montage frontal pour tous véhicule, en moins de 30 secondes par mues. (sans outils) Aujourd'hui aucun système ne prévoit en situation réelle une installation des chaines en moins de 30 secondes par roue, sans outils, sans avoir à démonter un boulon de la 5 roue, sans forcer ni faire tourner les roues pour la mise en place de celles-ci . Snow chains: The invention presented relates to front-mounted snow chains for all vehicles, in less than 30 seconds per mol. (Without tools) Today no system provides in real situation installation chains in less than 30 seconds per wheel, without tools, without having to disassemble a wheel bolt, without forcing or turning the wheels for the implementation in place of these.

Le montage de certaines chaines à neiges actuelles sont très complexes a installées : « donc peu pratique » et dans des conditions climatiques difficiles. Nous permettent de constater que 2 personnes sur 3 attendent la dernière minute pour installer leurs chaines à neige, bien qu'elles soit dans le coffre de leurs véhicule. 10 Les documents présentent un système d'actionnement toujours très complexe a installer. Il y a donc actuellement un besoin de proposer un système d'actionnement manipulable depuis le coté extérieur pneumatique et présentant un caractère amélioré par rapport au système de montage frontal existant. The assembly of some current snow chains are very complex installed: "therefore impractical" and in difficult climatic conditions. We can see that 2 out of 3 people wait until the last minute to install their snow chains, even though they are in the trunk of their vehicle. The documents show an actuating system which is still very complex to install. There is therefore currently a need to provide a manipulable actuation system from the pneumatic outer side and having an improved character compared to the existing front mounting system.

On a par ailleurs pensé à inventer un système de chaine qui élimine toutes les 15 difficultés que nous avons pu rencontrer auparavant. « plus facile à monter et à démonter » Donc plus de sécurité. En référence au dessin le dispositif comporte plusieurs innovations en matière de chaine à neige. We have also thought of inventing a chain system that eliminates all the difficulties that we have encountered before. "Easier to assemble and disassemble" So more security. In reference to the drawing the device includes several innovations in terms of snow chains.

20 La présente invention s'inscrit dans le cadre et propose pour se faire un dispositif dans lequel on retrouve une facilitée de montage, (30 secondes par roues) à la différence de tout autre modèle en vente aujourd'hui. The present invention is part of the framework and proposes to be a device in which there is a facility of assembly, (30 seconds per wheel) unlike any other model on sale today.

Les innovations du système frontal présenté sont : Un corps central rotatif celui-ci plaqué avec de solides élastiques contre la partie 25 extérieure de la roue. Huit bras flexibles, réglables et crochetés ,sont fixés sur l'axe central de façon à se déployer tel un éventail, et enveloppé la roue grâce a ses bras crochetés. The innovations of the frontal system shown are: A rotating central body which is pressed with strong elastics against the outer part of the wheel. Eight flexible arms, adjustable and hooked, are fixed on the central axis so as to unfold like a fan, and wrapped the wheel with its hooked arms.

Une roulette est fixée à l'extrémité de chaque bras flexible pour facilité l'installation et notamment le passage des bras sur la structure du pneu. A wheel is attached to the end of each flexible arm for ease of installation including the passage of arms on the tire structure.

30 Le dispositif d'attache comporte quatre élastiques qui viendrons s'accrocher depuis le corps central vers la partie extérieure de la roue pour plaquer le système sur la jante. Page 1 Coopérant pour une meilleure tension, une chaîne viendra refermer le système pour une sécurité optimale sur les deux bras les plus espacés, et de réguler l'équilibre de rotation Une chaîne équipée de croisillons, est fixée entre chaque bras flexible, à l'exception 35 des deux bras qui serviront pour le passage du système ,au niveau du contact entre le pneu et la svalte. La chaîne viendra s'envelopper sur le pneu tout , autour de la bande de roulement grâce à la spécificité de ses bras crochetés. The fastening device comprises four elastics which will hang from the central body to the outer part of the wheel to press the system on the rim. Page 1 Cooperating for better tension, a chain will close the system for optimum safety on the two most distant arms, and regulate the balance of rotation A chain equipped with braces, is attached between each flexible arm, to the exception 35 of the two arms that will be used for the passage of the system, at the contact between the tire and the svalte. The chain will come wrapped around the tire all around the tread thanks to the specificity of its hooked arms.

Apte a coopérer avec la bande de roulement du pneumatique . 40 caractérisé par le fait : qu'il n'y a plus besoin d'outillage ni de rotation de la roue pour le montage des chaînes à neige. Grâce notamment à la spécificité de fonctionnement et de ses bras flexibles, réglables et espacés, de manière particulière comme nous indique l'invention, celle-ci nous permet d'affirmer: que le système sera très rapide à installer sur les véhicules contrairement aux chaînes antérieures. Page 2 Réalisation : La réalisation de cette invention comporte plusieurs étapes comme indiqué sur le dessin. Le schéma n°l représente un des bras flexible tel qu'il doit être fabriqué pour une enveloppe optimale. Able to cooperate with the tread of the tire. 40 characterized by the fact that there is no longer any need for tools or rotation of the wheel for mounting the snow chains. Thanks in particular to the specificity of operation and its flexible, adjustable and spaced arms, in a particular way as indicated by the invention, this one allows us to affirm: that the system will be very fast to install on the vehicles unlike the chains earlier. Realization: The realization of this invention comprises several steps as indicated in the drawing. Diagram No. 1 represents one of the flexible arms as it must be manufactured for an optimal envelope.

Les huit roulettes (n°3) placées aux extrémités de chaque bras, facilite l'installation et permet de faire glisser le système sur la structure du pneu. The eight casters (# 3) at the ends of each arm facilitate installation and slide the system over the tire structure.

Le Schéma n°2 représente un mode d'implantation général du dispositif, de l'invention a un pneumatique de véhicule automobile Diagram No. 2 represents a general embodiment of the device, from the invention to a motor vehicle tire.

Le schéma n°3 montre le corps central (n°1 ) vue de face équipé d'un axe rotatif, et de 10 ses huit bras fixés sur l'axe, afin d'ouvrir les bras n°2 du système comme un éventail. Figure 3 shows the central body (No. 1) front view equipped with a rotary axis, and its eight arms fixed on the axis, to open the arms No. 2 of the system as a fan. .

Sachant que chacun des bras aura une épaisseur d'environ 2 millimètres, il faudra donc en fonction de leurs ordre d'ouverture qu'ils soit tous plus court de 2 millimètres par rapport au précédant. Pour que la pointe de chaque bras puisse atteindre le flanc intérieur du pneu sans gêner la rotation. 15 (soit une longueur d'environ 1,4 cm entre le premier et le dernier bras.) Sur le schéma n°4, on observe une position en phase refermée du système (n°2) relié sur l'axe central (n°l) . Le Schéma n°5 illustre une roue de profil, afin de mieux comprendre l'enveloppe qui est faite sur le pneu. Des chaines (n°7) avec croisillons sont fixées et reliées entre 20 chaque bras, permettant l'uniformité et l'accroche optimale du système. (voir le positionnement des chaines sur le schéma). Sachant que les deux bras les plus espacés permettent l'insertion du système sont volontairement refermés par une tige chaînée (n°4) pour plus de sécurité, et sont équilibre de rotation. L'espace entre les deux bras qui servent à l'insertion du système 25 entre la bande de roulement et le sol ne pose aucun problème de rotation, puisque nous avons tester celui-ci. Le passage entre les deux bras les plus espacés est à : -8 Km/h = moins de 2 dixièmes de seconde -15 Km/h = environ 1 dixième de seconde Knowing that each of the arms will have a thickness of about 2 millimeters, it will therefore be necessary according to their order of opening that they are all shorter by 2 millimeters compared to the preceding one. So that the tip of each arm can reach the inside of the tire without hindering the rotation. 15 (ie a length of about 1.4 cm between the first and the last arm). In FIG. 4, a closed phase position of the system (No. 2) connected to the central axis (FIG. ° l). Figure 5 illustrates a profile wheel, to better understand the envelope that is made on the tire. Chains (No. 7) with braces are attached and connected between each arm, allowing uniformity and optimum grip of the system. (see the positioning of the chains on the diagram). Knowing that the two most spaced arms allow the insertion of the system are voluntarily closed by a chained rod (No. 4) for more security, and are rotation equilibrium. The space between the two arms which serve to insert the system 25 between the tread and the ground poses no problem of rotation, since we have tested it. The passage between the two most distant arms is at -8 km / h = less than 2 tenths of a second -15 km / h = about 1 tenth of a second

Le schéma n°6 nous montre un système de fermeture,(n°4) entre les bras les plus 30 espacés, pour une tension optimale. Le schéma n°7 Dispositif d'attache comporte : - 4 crochets (n°6) fixés sur le corps central du système, sur lequel 4 solides élastiques (n°5) permettent de maintenir le système en contact avec la jante. Figure 6 shows a closure system (# 4) between the most spaced arms for optimum tension. Figure 7 Fastening device includes: - 4 hooks (n ° 6) fixed on the central body of the system, on which 4 elastic solids (n ° 5) make it possible to keep the system in contact with the rim.

35 Deux des huit bras (les plus espacés pour le passage de roue) sont équipés d'une fixation pour accrocher la chaine de tension, celle-ci servira aussi à l'équilibre de rotation. Sachant que le système à déjà été fabriqué par mes soins de façon artisanale (celui-ci fonctionne). 40 En référence au dessin et aux explications indiquées si dessus, l'invention est susceptible d'application industrielle de par son innovation et sa facilité de montage sur les roues. Page 3 Mode d'emploi 1) Ouverture des chaines sur le corps central 2) A l'aide des bras souples (matière composites ou aluminium) et du système de roulettes à chaque extrémités enveloppez la roue frontalement comme l'indique le dessin 3) Accrochez la chaire de sécurité pour une meilleure tension et un équilibre maximum de rotation 4) Une sécurité supplémentaire à été mise en place pour maintenir le système correctement plaqué contre la jante, se fait à l'aide d'élastiques très solides accrochées sur la face avant du corps central. Two of the eight arms (the most spaced for the wheel arch) are equipped with a fastener for hanging the tension chain, which will also serve for the balance of rotation. Knowing that the system has already been manufactured by me in a traditional way (it works). With reference to the drawing and explanations indicated above, the invention is susceptible of industrial application by its innovation and ease of mounting on the wheels. Page 3 Instructions for use 1) Opening the chains on the central body 2) Using the flexible arms (composite material or aluminum) and the caster system at each end, wrap the wheel frontally as shown in drawing 3) Hang up the safety chair for better tension and a maximum balance of rotation 4) Additional security has been put in place to keep the system properly pressed against the rim, is made with very strong elastics hung on the face front of the central body.

Fabriqués en matière composite pour plus de légèreté et de souplesse, les huit bras crochetés (n°2) servent à envelopper la roue. Page 4 Made of composite material for more lightness and suppleness, the eight hooked arms (n ° 2) are used to wrap the wheel. Page 4
