Abstract
An anti-skid tire chain for use on both soft and frozen terrain is disclosed. The chain comprises a pair of parallel side chains adapted to encircle opposite sides of a tire, a plurality of traction units such as rings aligned medially between the side chains and spaced one from the other around the tread surface of the tire, and intermediate chain networks connected at outer locations to the respective side chains and at inner locations to successive traction units. There are lugs on the traction units and studs on the intermediate chain networks. The lugs and the studs protrude outwardly from the tread surface of the tire.
Claims13
An anti-skid tire chain for use on both soft and frozen terrain, said chain comprising:
- a pair of parallel side chains adapted to encircle opposite sides of a tire;
- a plurality of traction units aligned medially between said side chains and spaced one from the other along the length of said side chains, said traction units including lugs adapted to protrude outwardly from said anti-skid tire chain;
- and
- a plurality of intermediate chain networks each of which is connected to a traction unit and connected to one of said side chains, said intermediate chain networks including studs adapted to protrude outwardly from said anti-skid tire chain, said studs each including a surface area for contacting the ground that is smaller than the surface area of each of said lugs for contacting the ground.
An anti-skid tire chain for use on both soft and frozen terrain, said chain comprising first and second parallel side chains adapted to encircle opposite sides of a tire, and a chain network extending between said side chains, said chain network comprising:
- a center portion aligned medially between said side chains along the length of said side chains, said center portion including center elements with lugs adapted to protrude radially outwardly from said anti-skid tire chain;
- a first side portion including intermediate chain networks each of which is connected to at least one center element and to said first side chain;
- and
- a second side portion including intermediate chain networks each of which is connected to at least one center element and to said second side chain, said intermediate chain networks each including studs adapted to protrude radially outwardly from said anti-skid tire chain, and each said stud including a surface area for contacting the ground that is smaller than the surface area of each of said lugs for contacting the ground.
