Abstract:
1. A fence comprising: a plurality of tires, each tire having a cylindrical axis and a tread portion and two spaced sidewalls joined to said tread portion and defining a wheel opening centered on said axis, and wherein: said tires are laid with one of their sidewalls facing downward, said tires are arranged in original locations adjacent one another in a line defining at least one row, with an original row profile, said row has at least a first course and a second course of said tires therein, the tires in the first course being a bottom course and laid on a stationary supporting surface so as to be slidable together alone said supporting surface and laterally of said original row profile, the tires in the second course being placed on top of the tires of said first course and increasing the height of the fence but maintaining the original row profile, adjacent tires in the first course and adjacent tires in the second course being spaced apart along said original row profile and adjacent tires in the second course being placed in staggered relationship to the tires of such that adjacent tires in the second course are located between and partially overlap adjacent tires in the first course along said original row profile binding devices holding said tires in said first course together and holding said tires in said second course together; and wherein: said binding devices are sufficiently loose to enable flexibility of the fence in the event of a collision of a moving vehicle with the fence, whereby those of said tires nearest the initial collision impact location and, sequentially others of said tires further from the said impact location, are moveable out of their original locations within said original row profile, to form a second row profile and lessen tension initially placed on the binding devices by impact of the vehicle with the fence and thereby lessen the potential for breakage of the binding devices and thereby enable a change of the row profile by said collision from said original row profile to said second profile without breaking the row apart while gradually decreasing the vehicle velocity; and the fence further comprising: additional courses of said tires superimposed on said second course and maintaining said original row profile and wherein: some of said binding devices comprise a first set of elongate tread strips which have ends and extend through said wheel openings and are wrapped around at least two of said tires which are adjacent to each other in said first course and bind said adjacent tires together in said first course; some of said binding devices comprise assemblies of elongate tire tread strips which have ends and are connected in series and extend through vertically aligned portions of said wheel openings of tires in vertically superimposed courses and are wrapped around vertically aligned portions of said tires in multiple courses and bind said tire portions together; said tread strips being elongate and having ends; and wherein the end of at least one of said tread strips is connected to the end of another of said tread strips to close said one and another tread strips together after wrapping, and binding said tires together in superimposed courses.
