Abstract
Abstract A deformable elongate upright hollow cylindrical body is formed by a plurality of concentrically stacked tire casings which are bound together by cables. Retaining anchors, each having an eye encircling one of the cables, holds the cylindrical body in a predetermined position to function as a vehicle barrier. Used, empty crushable containers within the hollow body provide additional energy absorption. A barricade wall is fabricated from several deformable bodies, each in tangential contact and secured by additional cables.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
130 words
An energy absorbing device fabricated substantially of salvaged material for receiving the impact of a moving vehicle and dissipating at least a portion of the kinetic energy thereof by deformation, said energy absorbing device comprising: a. a plurality of concentrically arranged and stacked used whole tire casings, each positioned horizontally having the side wall thereof in surface contact with the side wall of each adjacent casing to form a deformable elongate upright hollow cylindrical body; b. securement means including at least three equally spaced cable members each encircling the side wall of said hollow cylindrical body for holding said casings in said stacked arrangement; c. at least one used empty crushable container within said hollow cylindrical body; and d. anchor means for affixing said cylindrical body to a predetermined surface.
Claim 2
Dependent Claim
130 words
An energy absorbing device fabricated substantially of salvaged material for receiving the impact of a moving vehicle and dissipating at least a portion of the kinetic energy thereof by deformation, said energy absorbing device comprising: a. a plurality of concentrically arranged and stacked used whole tire casings, each positioned horizontally having the side wall thereof in surface contact with the side wall of each adjacent casing to form a deformable elongate upright hollow cylindrical body; b. securement means including at least three equally spaced cable members each encircling the side wall of said hollow cylindrical body for holding said casings in said stacked arrangement; c. at least one used empty crushable container within said hollow cylindrical body; and d. anchor means for affixing said cylindrical body to a predetermined surface.
Claim 3
Dependent Claim
18 words
The energy absorbing device of claim 1, wherein said anchor means includes an eye encircling said cable means.
Claim 4
Dependent Claim
20 words
The energy absorbing device of claim 1, including a plurality of empty crushable containers held within said hollow cylindrical body.
Claim 5
Dependent Claim
15 words
