ABSTRACT:
This invention discloses a snow chain comprising at least three chains or wires arranged and connected to each other in a network providing two series of diamond-shaped openings adjacent and parallel to one another, wherein the two extremities of the first chain or wire respectively extending from the two end-most junctions between the first and second chains or wires are respectively connected to the two extremities of a first retainer cord, which first retainer cord with connectors for removably connecting the two extremities thereof is linked to the first chain or wire at each zig-zag point in a sliding arrangement. One extremity of the second chain or wire extending from one of the two end-most junctions between the first and second chains or wires includes, firstly, a connector for removably connecting that extremity to one extremity of the third chain or wire extending from one of the two endmost junctions between the second and third chains or wire and, secondly, an angled link disposed at the mid-length of that extremity that engages an angled link included in the other of the two end-most junctions between the second and third chains or wires. A second retainer cord with connector for removably connecting the two extremities thereof to one another is linked to the third chain or wire at the one extremity removably connected to the one extremity of the second chain or wire and at each zig-zag point in a sliding relationship.
