Abstract
A device for mounting snow chains on a vehicle tire has a base adapted to be placed on the ground, downwardly and outwardly inclined terminal portions providing runways for a vehicle wheel and a transversely concave intermediate mounting surface for supporting the vehicle tire. The top of the device has laterally-extending grooves allowing each chain cross-over to rest freely therein with ample room to properly fit the chain. A lobe is located in the center for the vehicle tire to rest upon. The outer edges of the device extend upwardly to center the vehicle tire and prevent it from slipping off the sides of the device. The bottom has saw-toothed lateral members to hold the device from slipping on the road surface and to distribute the weight of the vehicle evenly upon the road surface.
Claims18
A device for affixing a tire chain to a vehicle tire comprising:
- a base adapted to be placed on a supporting surface, the base having;
- downwardly and outwardly inclined terminal means for providing runways for a vehicle wheel, which have a plurality of upwardly extending conical-shaped projections for precluding said vehicle from slipping thereon;
- an intermediate mounting surface for supporting the vehicle wheel;
- a plurality of upwardly extending main members which engage the outer face of the vehicle tire as the vehicle is being driven onto or off of the device, said main members having a plurality of upwardly extending conical-shaped projections for precluding said vehicle tire from slipping thereon;
- a plurality of relieved areas as a means for receiving the gripping members of a tire chain;
- and
- lateral outer edges extending upwardly, providing means for centering the vehicle tire upon the device and precluding the vehicle tire from slipping off the sides of the device.
A device for affixing a tire chain to a vehicle tire comprising:
- a base adapted to be placed on a supporting surface, the base having;
- downwardly and outwardly inclined terminal means for providing runways for a vehicle wheel, which have a plurality of upwardly extending conical-shaped projections for precluding said vehicle from slipping thereon;
- an intermediate mounting surface for supporting the vehicle wheel;
- a plurality of upwardly extending main members which have rounded edges and engage the outer face of the vehicle tire as the vehicle is being driven onto or off of the device, said main members having a plurality of upwardly extending conical-shaped projections for precluding said vehicle tire from slipping thereon;
- a plurality of relieved areas as a means for receiving the gripping members of a tire chain;
- lateral outer edges extending upwardly, providing means for centering the vehicle tire upon the device and precluding the vehicle tire from slipping off the sides of the device;
- and
- a plurality of downwardly-extending cleats arranged in a staggered pattern on the underside of the base for precluding the device from slipping on the supporting surface.
A device for affixing a tire chain to a vehicle tire comprising:
- a base adapted to placed on a supporting surface, the base having;
- downwardly and outwardly inclined terminal means for providing runways for a vehicle tire;
- four upwardly extending main members which engage the outer face of a vehicle tire as a vehicle is being driven onto or off of the device;
- five relieved areas for receiving the gripping members of a tire chain;
- a plurality of conical-shaped projections extending upwardly from the both the terminal means and the main members for precluding said vehicle tires from slipping thereon;
- and
- a plurality of downwardly-extending cleats arranged in a staggered pattern on the underside of the base for precluding the device from slipping on the supporting surface.
A device for affixing a tire chain to a vehicle tire comprising:
- a base adapted to placed on a supporting surface, the base having;
- downwardly and outwardly inclined terminal means for providing runways for a vehicle tire;
- at least four upwardly extending main members which engage the outer face of a vehicle tire as a vehicle is being driven onto or off of the device;
- at least five relieved areas for receiving the gripping members of a tire chain;
- a plurality of conical-shaped projections extending upwardly from the terminal means and main members for precluding said vehicle tires from slipping thereon;
- and
- a plurality of downwardly extending members projecting from the underside of said base providing a means for precluding the device from slipping on the supporting surface.
A device for affixing a tire chain to a vehicle tire comprising:
- a base adapted to placed on a supporting surface, the base having;
- downwardly and outwardly inclined terminal means for providing runways for a vehicle tire;
- four upwardly extending main members which define a generally arcuate area and engage the outer face of a vehicle tire as a vehicle is being driven onto or off of the device, wherein the two innermost main members are closest to the center of the device and are downwardly inclining toward the center of the device, and two outermost main members, which are closest to the terminal means and generally are parallel to the ground;
- five relieved areas for receiving the gripping members of a tire chain;
- a plurality of conical-shaped projections extending upwardly from the terminal means and main members for precluding said vehicle tires from slipping thereon;
- and
- a plurality of downwardly-extending cleats arranged in a staggered pattern on the underside of the base for precluding the device from slipping on the supporting surface.
