Easy mount tire chains
View Patent ↗Configurations and installation methods for vehicle tire chains which provide tire chains especially easy to mount, and provide improvements in performance and vendor supply.
1. A vehicle tire chain, for installation on a vehicle wheel resting on the ground, or roadway, comprising
a generally circular, flexible side member on the inner face side of the tire,
a generally circular, flexible side member on the outer face side of the tire,
an attachment device provided on each side member to attach the ends for each to form a loop on the wheel,
a multiplicity of flexible cross members between the two side members, arrayed on the tire tread in a repetitive pattern, and
the pattern is of such density that there is always a cross member in the tire to ground contact area during operation, and
the installation procedure includes the step of imposing adjacent cross members upon the edges of the tire to ground contact area, such that one or both of said adjacent cross members are deflected from their natural positions in the pattern, and
said adjacent cross member or members deflected from their natural positions are slidably connected to the outer face side member and are extended through the sliding connection radially inward and beyond the side member a distance adequate to allow for the deflection during installation, and are adapted for tension means to be connected to the radially inward end of the extension.
2. The chain of claim 1 in which extensions of said adjacent cross members radially inward and beyond the outer face side member include a non return means such that when an extended cross member is pulled radially inward through the connection to the side member, to its fully installed position, it is mechanically prevented by said non return means from withdrawing radially outward through said connection.
