Abstract
The invention relates to an anti-skid device for vehicle wheels for travelling on ice and snow with a disc-like casing connected to the wheel rim with resilient-elastic anti-skid arms, constructed in such a way that in the position of use their ends can be swung out radially into the tire tread area while adapting to the rolling shapes of the tire and can be swung in when not in use, so that a device is obtained which can effortlessly be fitted whenever required, which is inexpensive to manufacture and which permits higher speeds than are possible when travelling with snow chains or spiked tires.
Claims24
An anti-skid mechanism for a vehicle wheel which includes a wheel rim having an axis of rotation comprising:
- a first member affixed to said wheel and extending generally transversely relative to said wheel axis;
- a second member axially spaced from said first member on a side thereof opposite said wheel and also extending generally transversely relative to said axis;
- means for rotating said second member relative to said first member about said axis;
- a plurality of anti-skid arms pivotally mounted on said first member;
- and lever means pivotally mounted between each of said anti-skid arms and said second member to drive said anti-skid arms between an operative position and an inoperative position by rotation of said second member relative to said first member.
