Abstract

A snow chain for the automobile tires employing a single or a plurality of traction cords disposed circumferentially over the tread surface of the tire in a zig-zag pattern or diamond pattern, which traction cords are held in position by a pair of star-shaped tie cord assembly respectively disposed on each side of the tire, is disclosed. The outer points of each of said star-shaped tie cord assembly are connected to said traction cord in such a way that the tension on tie cords stretches the traction cord into a zig-zag or diamond pattern as said traction cord is being tightened over the tire tread surface. The inner points of each of said star-shaped tie cord assembly are slidably engaged by a retaining cord, which sliding relationship enables the retaining cord loop to expand and be slipped over the circumference of the tire, which arrangement ensures the easy installation and take off of said snow-chain.

Claims4

Dependent claims

An "easy to install continuous snow chain" comprising:

(a) an outside star-shaped tie cord assembly;
(b) an inside star-shaped tie cord assembly;
(c) a traction cord loop of zig-zag pattern having a stretched circumference length slightly greater than the circumference length of the tread surface of the tire, wherein each of the outside points of said traction cord loop of zig-zag pattern is connected to each of the outer points of said outside star-shaped tie cord assembly and each of the inside points of said traction cord loop of zig-zag pattern is connected to each of the outer points of said inside star-shaped tie cord assembly;
(d) an outside retaining cord loop slidably or removably engaging each of the inner points of said outside star-shaped tie cord assembly and having one or more adapter means for opening and closing wherein the tension on the closed loop of said outside retaining cord loop creates tension on said outside star-shaped tie cord assembly and said traction cord loop of zig-zag pattern causing said snow chain to be tightly disposed around the tire;
and
(e) an inside retaining cord loop slidably or removably engaging each of the inner points of said inside star-shaped tie cord assembly and having one or more adapter means for opening and closing wherein the tension on the closed loop of said inside retaining cord loop creates tension on said inside star-shaped tie cord assembly and said traction cord loop of zig-zag pattern causing said snow chain to be tightly disposed around the tire.

3 more elements

An "easy to install continuous snow chain" comprising:

(a) an inside retaining cord loop comprising one or more of slidable cords;
(b) an inside star-shaped tie cord assembly wherein each of the inner points of said inside star-shaped tie cord assembly is slidably engaged by said one or more of slidable cords comprising said inside retaining cord loop, one or more straight segments of said inside star-shaped tie cord assembly being comprised of the extension of said one or more of slidable cords in a slidable arrangement;
(c) a traction cord loop of zig-zag pattern having a stretched circumference length slightly greater than the circumference of length of the tread surface of the tire, wherein each of the inside points of said traction cord loop of zig-zag pattern is connected to each of the outer points of said inside star-shaped tie cord assemby, one or more straight segments of said traction cord loop of zig-zag pattern being slidably comprised of the extension of said one or more of slidable cords comprising said one or more straight segments of said inside star-shaped tie cord assembly;
(d) an outside star-shaped tie cord assemby wherein each of the outer points of said outside star-shaped tie cord assembly is connected to each of the outside points of said traction cord loop of zig-zag pattern, one or more straight segments of said outside star-shaped tie cord assembly being slidably comprised of the extension of said one or more of slidable cords comprising said one or more of straight segments of said traction cord loop of zig-zag pattern;
(e) an outside retaining cord loop engaging each of the inner points of said outside star-shaped tie cord assembly;
and
(f) means for connecting the extension of said one or more of slidable cords comprising one or more of straight segments of said outside star-shaped tie cord assembly to said outside star-shaped tie cord assembly, said means for connecting providing and maintaining a tension on said inside retaining cord loop.
