Vehicle crash wall

Abstract

A vehicle crash wall with a series of overlapping metal plates attached to a retaining wall by means of a metal sleeve inserted into a female receiving tube. Located between the metal plates and retaining wall is an impact absorbing material. The metal sleeves, 3, are perpendicularly attached to the metal plates, 1, by inserting them into slip joints, 16, and inserting metal pins, 11, vertically through the top of said metal sleeves and into swivel hinges, 10, located beneath said slip joints. The female receiving tubes, 4, are located inside the middle of the retaining wall, 8, perpendicularly extending approximately half-way behind said retaining wall. Said metal sleeves are vertically supported by rollers arms, 5. Said metal plates are perpendicularly supported by cable hold backs, 6, and horizontally by support cables, 13. The force of the impact is evenly dissipated along the length of metal plates and energy absorbent material. This dramatically reduces the risk of injury to the driver and damage to his vehicle and the wall.

I claim:  
     
         1 . A vehicle crash wall which comprises: 
 (a) a series of overlapping metal plates, located horizontally to a retaining wall, which are connected by cables and square metal sleeves inserted into female receiving tubes perpendicularly located inside said retaining wall,    (b) said square metal sleeves supported vertically by rollers attached perpendicularly to said metal plates,    (c) said metal plates having a slip joint and swivel hinge containing a pin,    (d) impact absorbent material located between said metal plates and said retaining wall.    
     
     
         2 . The vehicle crash wall of  claim 1  wherein said metal sleeves are comprised of any suitable material.  
     
     
         3 . The vehicle crash wall of  claim 1  wherein said metal sleeves are operated by hydraulic pressure.  
     
     
         4 . The vehicle crash wall of  claim 1  wherein said metal sleeves are operated by pneumatic pressure.  
     
     
         5 . The vehicle crash wall of  claim 1  wherein said metal sleeves have a different geometric design.  
     
     
         6 . The vehicle crash wall of  claim 1  wherein said metal sleeves are supported vertically by a rail system having multiple vertical posts imbedded within the track.  
     
     
         7 . The vehicle crash wall of  claim 1  wherein said metal plates are comprised of any suitable material.
