Definitions
- the present invention is mainly aimed at making it easier to install and maintain the snow chains on the tires of motor vehicles by using one or more flexible pads previously attached to one or more places of a snow chain laid flat on the tire. ground.
- the snow chain drive and retainer of the invention is of a shape, size and configuration suitable for the type of receiving snow chain. It is made of a material that is at once flexible, elastic and permanently deformable, of the elastomer, plastomer, copolymer or other natural or synthetic material type, endowed with technical characteristics allowing a block of this material to penetrate inside under crushing. of the tread of an automobile wheel tire and remain sufficiently gripped in this position to, on the one hand, raise one end of a snow chain at the start of winding around said tire so as to bring the latter close to the other end of said snow chain at the end of winding and, on the other hand, hold said snow chain installed on the tread of the fitted tire in position, without the latter being able to come loose. move laterally and leave said tire under the rolling effect.
- a snow chain is most often made up of a set of metal chain portions, placed around the tires of a motor vehicle to strengthen the vehicle's grip on the traffic lane, when the latter is made slippery by a layer of fresh or packed snow.
- now chain To improve its characteristics and optimize its performance, the chain commonly called “snow chain” has gradually evolved to give rise to a large number of different and varied product concepts for the same purpose.
- snow chains known as universal chains designed to adapt to all sizes of wheels and claimed to be easier to install.
- Some models no longer look like chains but rather bands studded or provided with various elements intended to hang on the snowy ground, most often fixed directly to the rims of the wheels of the vehicle, for example, the bands known as "snow socks » But if the assembly seems simplified, the effectiveness is questionable in certain situations.
- the technical problems to be solved lie mainly in the shape and presentation of the snow chains currently on the market, but above all in the difficulties of access. Indeed, if access to the front face of the wheel of a vehicle, to its rim and to its tire remains easy, it is not the same for access to the rear face of the wheel which is close to steering mechanics and which in fact poses a lot of problems for ordinary people unaware of automobile mechanics.
- zone axial a zone intended to bear exclusively on the tread of the tire, hereinafter referred to as " zone axial link ” which alone or in combination form one or more geometric figures whose function consists of attaching the tire to the snow-covered ground and, on the other hand, on both sides.
- axial zone a zone intended to bear on each of the sidewalls of the tire, designated “lateral zone” and preferably consisting of a chain attached to each of the "axial links” or of the geometric shapes formed by those here in the "axial zone".
- the “axial zone” covers the tread of the tire and the “lateral zones” cover the tire. on the one hand the front side part of the tire and on the other hand the rear side part.
- the author of the present invention was inspired by the particular characteristics of the isobutylene-isoprene copolymer rubber used and treated for the manufacture of chewing gum, to imagine an interchangeable training and support pad made of a natural or synthetic material, easily attached in one or more copies on most models of snow chains and capable of penetrating by crushing and under the weight of the wheel of a vehicle in the tread patterns of a tire.
- the driving and holding shoe is arranged and fixed to one or more places in the “axial zone” of a snow chain spread out on the ground, so as to be crushed between on the one hand the tire of the vehicle wheel and the ground, when the vehicle is in motion.
- the flexible and elastic material which constitutes the driving and holding shoe deforms under the effect of the crushing and then penetrates inside the tire treads to adhere sufficiently to them and consecutively drive and hold the part of the chain. snow associated with it, in contact with the tread of the tire.
- the snow chain remains pressed against the tread of the tire until its end thus retained is brought by the rolling bearing to a position close to the ground and to the other end. of the snow chain.
- the mechanical connection of the two opposite ends of the snow chain and the locking of the latter on the vehicle wheel is thus greatly facilitated.
- the driving and holding shoe is positioned and fixed at several successive locations along the length of the “axial zone” of the snow chain, so that the driving effect in the installation is amplified. and maintaining the snow chain on the tread of the reinforced tire during the rolling of the wheel and the movement of the vehicle.
- the basic rubber used is designed by a mixture of components carefully dosed, said components being mixed for precise times and temperatures that can sometimes reach 95 ° C to 98 ° C, to achieve characteristics compatible with the desired effect, namely: fluidity allowing the complete filling of all types of sculptures encountered, permanent deformation to keep said filling of the sculptures in position, adhesion by compression on the elastomer of a wet tire, mechanical resistance and sufficient contact force with the metal to drive and maintain in contact the snow chain with the tread of a tire for at least half a turn of the wheel (from the crushing point to the diametrically opposite point), the shear strength sufficient to ensure the maintenance of the chain-nei ge on the tread of the tire during movement (at low speed) of the vehicle and finally the aging and mutation of the material in use to allow the disconnection of the drive shoe from the tread and the chain - snow after use.
- each drive and holding pad has a fixing means to allow it to be securely attached to either side of the "axial zone", so as to avoid any movement during the passage of the wheel and crashing of the pad or when braking the equipped wheel when the pad is in contact with the traffic lane, for example one or more carabiners, a quick-connect and quick-disconnect coupling, or any other quick-release type coupler. strap, etc.
- the driving and holding shoe is installed on a standard metal snow chain consisting mainly when it is spread out on the ground, of two opposite side chains called “ side chain”.
- side chain consisting mainly when it is spread out on the ground, of two opposite side chains called “ side chain”.
- the “axial shapes” are connected to each other by their free tops by means of a chain called “connecting chain” preferably of the same constitution as the “side chain” and the “axial link”.
- each of the ends of the snow chain is equipped with at least one mechanical quick-hitch device called a “chain hitch” making it possible to connect the ends of the snow chain together and to adjust. the clamping thereof on the tread of the tire.
- the driving and holding pad consists of a block of flexible, elastic and permanently deformable material, natural or synthetic, capable of deforming when it is crushed by the tire of a vehicle wheel and consecutively penetrate inside the treads of said tire of said wheel to remain adhered to the walls and to the bottom of said treads for a predetermined minimum time.
- the driving and holding shoe is of shape, dimensions and design allowing it to be attached and mechanically fixed to one end of the snow chain to be installed, such that when it is crushed by the tire of the wheel of a vehicle, it penetrates inside the sculptures of the tread thereof and keeps the snow chain pressed against said tread of the tire for the drive in the rotational movement of the wheel.
