Abstract
The invention relates to an anti-skid device for vehicle wheels, comprising a plurality of U-shaped elements radially mounted on the wheel tire, and two series of connecting levers pivoted on each arm of said U-shaped elements. In order to provide an automatic mounting operation of the device on a vehicle wheel by simply advancing the wheel on the device, each arm of each of the U-shaped elements carries retaining means for said levers, which removably retain the U-shaped elements and levers in a relative position wherein each of said U-shaped elements forms a pre-set angle with the levers adjacent to the same, said angle corresponding to that formed when the device is mounted on the tire.
Claims10
An anti-skid device or skid chain for vehicle tires mounted on wheels comprising:
- a plurality of U-shaped elements for radial mounting on said tires, each of said U-shaped elements including a base portion and first and second arm portions;
- a first series of connecting levers each disposed between and pivotally affixed on the ends thereof to adjacent ones of said first arm portions;
- a second series of connecting levers each disposed between and pivotally affixed on the ends thereof to adjacent ones of said second arm portions;
- interlocking means for selectively substantially interlocking said U-shaped elements to said levers of said first and second series of levers in a range of positions such that said first and second arms of said U-shaped elements are disposed within a preselected range of angles relative to said levers of said first and second series;
- and
- locking means for locking said levers of said first series to adjacent said levers of said first series within a preselected degree of movement, and for locking said levers of said second series to adjacent said levers of said second series within a preselected degree of movement.
