ABSTRACT:
A tire chain device of the type which has a rigid structure positioned on the inner side of the wheel upon which it is installed, said rigid structure being comprised of an adjustable length horizontal strap and two rigid depending straps pivoted from either end thereof in a manner that restricts pivoting more than 90.degree., the two ends of the horizontal strap of said inner structure being connected by two short cross links to an adjustable length outer strap, and the lower end of each depending strap being removably connected by two long cross links to a plurality of posts having expanded ends spaced along the exposed side of the outer strap. In another mode of the invention the inner structure is comprised of five rigid straps including four of equal length and shape pivotally depending from one horizontal strap such that they form five sides of an octagon when pivoted to their maximum outward extent. The second mode of the device adjusts to different size wheels by the repositioning of the depending straps at their pivot points on the horizontal strap. The outer strap is slotted near one end for vertical support of the inner structure in the formation of a warning triangle.
