Abstract
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.
Claims24
A device for increasing friction of a tire on a slippery surface comprising:
- a center housing having a top side, a bottom side and an interior and wherein the bottom side of the center housing is secured to a wheel assembly;
- a plurality of connection sectors located within the interior of the center housing;
- and
- a plurality of wires having a length, a first end and a second end and wherein the first end of one respective wire is secured within a respective one of the plurality of connection sectors wherein each respective wire passes through a channel located in each respective one of a plurality of friction grips and wherein the friction grips are independently secured over the tire of a wheel in an active second position and wherein a friction grip is secured directly to the center housing while the device is in an inactive first position so as to extend both axially and radially outwardly between the center housing and a sidewall of a rim of the wheel.

- a plurality of wires having a length, a first end and a second end and wherein the first end of one respective wire is secured within a respective one of the plurality of connection sectors wherein each respective wire passes through a channel located in each respective one of a plurality of friction grips wherein the friction grips have a length which is greater than a distance between the center housing and a sidewall of a rim and wherein the friction grips are independently secured over the tire of a wheel in an active second position and wherein a friction grip is secured in a non-perpendicular manner directly to the center housing while the device is in an inactive first position;
- a protrusion on a first end of each of the friction grips wherein the protrusion is partially inserted within an opening of the connection sector while the device is in the inactive first position;
- wherein centripetal force created from the rotation of the device forces debris out of the opening of the connection sector;
- and
- wherein the friction grips extend both axially and radially outwardly between the center housing and the sidewall of the rim of the wheel.
