| 20100170603 | Easily mountable and removable universally adjustable traction apparatus for vehicle tires - The primary difficulty with equipment applicable to automobile tires to increase traction on snow-covered ground is mounting the equipment to the tire. The subject apparatus includes a base plate having multiple radially extending slots within which are slidably mounted radially extending rods to which are attached tire engaging claw members that overlap the periphery of the tire. A control plate is mounted onto the base plate and a gear mechanism is mounted between the two plates so that the gear mechanism may be operated to draw the claws inwardly to impose a retention pressure on the periphery of the tire. Means are provided to lock the apparatus in a tire tread engaging position. To remove the apparatus, the locking means are released and the claws are radially extended away from the tire so that the entire assembly may be removed from the tire. | 07-08-2010 |
| 20140367014 | MOTOR VEHICLE ANTI-SKID CRAWLER - The present invention discloses a motor vehicle anti-skid crawler comprising multiple sets of anti-skid dental plates surrounding the outer circumference of the tire and more circumferential links which chain the anti-skid dental plates in turn together, wherein: each set of the anti-skid dental plates includes a main shift-force plate, and a plurality of bifurcated shift-force plates which are formed by respectively extending outwardly at a angle from each end of the main shift-force plate. The improved anti-skid crawler dental plate of the present invention, the cross section of which inserted into the ice-snow, desert, sludge and marsh is huge, makes the pushing torque of the running vehicle to the ground very strong, and makes the vehicle run very speedily and smoothly. | 12-18-2014 |
| 20090314405 | Tire traction device - A traction device attachable to a tire mounted on a tire rim, the tire defining a pair of substantially annular and substantially opposed tire side walls, the tire also defining a tire thread extending between the tire side side walls, the traction device comprising: a first jaw, the first jaw defining a first jaw free end, the first jaw including a first tire gripping element provided substantially adjacent to the first jaw free end; a second jaw, the second jaw defining a second jaw free end, the second jaw including a second tire gripping element provided substantially adjacent to the second jaw free end; the first and second jaws being operatively coupled to each other so as to be movable between an open configuration and a closed configuration, the first and second tire gripping elements being closer to each other when the first and second jaws are in the closed configuration than when the first and second jaws are in the open configuration; the traction device further comprising a traction element extending between the first and second jaws substantially opposed to the first and second jaw free ends; wherein, when the traction device is operatively mounted to the tire with the first and second jaws in the closed configuration, the traction element extends across the tire thread and the first and second tire gripping elements grip a respective one of the tire side walls so as to pinch the tire between the first and second tire gripping elements. | 12-24-2009 |

| 20110220262 | TIRE CHAINS - A customizable tire chain including U-shaped members, grouser bars, and connecting segments. The U-shaped members each have a first leg, second leg, and transverse portion that extends between the first and second legs. The first and second legs are positioned to receive an outer edge portion of a tire therebetween. The connecting segments may connect the first legs, second legs, or transverse portions of the U-shaped members together. A first side of each of the grouser bars includes a traction structure. The second side of each of the grouser bars is removably coupled to the transverse portion of a corresponding one of the U-shaped members. In some embodiments, first and second ends of the grouser bars each extend laterally beyond the transverse portion of the corresponding U-shaped member. In such embodiments, the grouser bars may be coupled together at their first and second ends by the connecting segments. | 09-15-2011 |

| 20120125503 | DEVICE FOR INCREASING TIRE FRICTION AND METHOD OF USING THE SAME - A device and method for increasing tire friction is provided. The device is especially suitable for use on slippery roads, such as roads which have snow and/or ice. The device is permanently secured to the vehicle wheel assembly and easily installed over the tire for use. The device has a plurality of friction grips which independently move from an inactive first position secured to a sidewall of a housing center of the device to an active second position secured over the tire of the vehicle wheel assembly. | 05-24-2012 |
