ABSTRACT:
A vehicle wheel anti-slip device which is removably mountable on a vehicle for adding traction in snow, ice, etc. The device includes a frame having a generally rigid polygonal shape, a plurality of ground engaging claws including a first leg portion locatable over the perimeter of the vehicle wheel and a second leg portion and at an angle to the first leg portion and locatable over the front side of the vehicle wheel. The device also includes a plurality of support brackets which are pivotally mounted on the frame, and the claws are each pivotally mounted to a respective one of the support brackets. In addition, a tension force device including a tension spring and chords connected to each of the support brackets biases the plurality of claws simultaneously generally towards the center axis of the tire so as to be pressed thereagainst. In addition, a tension spring member connects each of the support brackets with a respective one of the claws on the second leg portions such that the claws are biased so as to pivot in a direction towards the center axis when mounted upon the vehicle wheel. A respective stop member limits the pivotal movement of the claws with respect to the respective support bracket. The present invention, therefore, has significant advantages, such as (1) it is very durable and reliable, (2) it can be very easily installed, and (3) it can have universal applicability to various wheels.
