Bollards, barriers and baffles formed from radial type tread

Abstract

A used radial tyre tread, folded into a minimum of three loops and held in compression, in a lateral external circlip, to form a flexible, resilient, abrasion resistant bollard with anisotropic properties. By extending the lateral external circlip, longitudinally, more tyre treads can be added to form a baffle or a barrier. The removal of the tread section significantly reduces the bulk of the waste tyre.

         8 . A bollard comprising a hoop of reinforced radial tyre tread and a circlip wherein the tread is folded into at least three loops and the circlip holds the central loop under compression thereby enabling the bollard to exert anisotropic properties for dissipating kinetic energy. 
     
     
         9 . A bollard as claimed in  claim 8 , in which the said circlip is secured to the ground. 
     
     
         10 . A bollard as claimed in  claim 9 , in which said circlip and said central loop are buried in the ground. 
     
     
         11 . A bollard as claimed in  claim 8 , further comprising two or more reinforced radial tyre treads each folded into at least three loops with the central loop being held under compression by the circlip. 
     
     
         12 . A bollard as claimed in  claim 8 , in which said circlip is wider than the tread forming the central loop. 
     
     
         13 . A bollard as claimed in  claim 8 , in which said circlip has at one end an integrated cuff for connecting with another circlip. 
     
     
         14 . A bollard as claimed in  claim 8 , further including a collar for connecting two circlips. 
     
     
         15 . A bollard as claimed in  claim 8 , further comprising two or more reinforced radial tyre treads each folded into at least three loops with the central loop being held under compression by the circlip, said circlip being wider than the tread forming the central loops and in that said circlip has at one end an integrated cuff for connecting with another circlip. 
     
     
         16 . A bollard as claimed in  claim 8 , further comprising two or more reinforced radial tyre treads each folded into at least three loops with the central loop being held under compression by the circlip, said circlip being wider than the tread forming the central loops and further including a collar for connecting two circlips. 
     
     
         17 . A bollard as claimed in  claim 15 , in which the said circlip is secured to the ground. 
     
     
         18 . A bollard as claimed in  claim 15 , in which said circlip and said central loops are buried in the ground. 
     
     
         19 . A bollard as claimed in  claim 16 , in which the said circlip is secured to the ground. 
     
     
         20 . A bollard as claimed in  claim 16 , in which said circlip and said central loops are buried in the ground.
