Indicator Post

Abstract

This invention relates to an indicator post comprising an elongate sheet of high strength engineering polymer (HSEP) material, the elongate sheet being resiliently bendable to enable the indicator post to revert upright after an impact. An associated reinforcement means attachable to a driveable portion of the indicator post is also disclosed.

1 . An indicator post comprising an elongate sheet of high strength engineering polymer (HSEP) material, the elongate sheet being resiliently bendable to enable the indicator post to revert upright after an impact. 
   
   
       2 . The indicator post of  claim 1 , wherein the HSEP material is a UV stabilised extrudable polycarbonate. 
   
   
       3 . The indicator post of  claim 1 , wherein the UV stabilised extrudable polycarbonate is selected from any one of Makrolon 3101, Panlite polycarbonate, Novarex polycarbonate, Carbine 8073 polycarbonate or any combination thereof. 
   
   
       4 . The indicator post of  claim 1 , wherein the elongate sheet has a substantially arcuate sectional profile. 
   
   
       5 . The indicator post of  claim 1 , wherein the elongate sheet has a substantially channel shaped profile. 
   
   
       6 . The indicator post of  claim 1 , wherein the width of the elongate sheet is approximately between 40 mm and 140 mm. 
   
   
       7 . The indicator post of  claim 1 , wherein the thickness of the elongate sheet is approximately between 1 mm and 6 mm. 
   
   
       8 . The indicator post of  claim 1 , further including ground engaging means to resist upward movement of the post after installation into the ground. 
   
   
       9 . The indicator post of  claim 1 , further comprising an installation depth indicator. 
   
   
       10 . The indicator post of  claim 1 , further comprising a driveable base portion attached to the elongate sheet. 
   
   
       11 . The indicator post of  claim 10 , wherein the driveable base portion includes a star picket section. 
   
   
       12 . The indicator post of  claim 1 , further comprising reinforcement means to reinforce a drivable portion of the elongate sheet. 
   
   
       13 . The indicator post of  claim 12 , wherein the reinforcement means substantially matches the shape of the drivable portion of the elongate sheet. 
   
   
       14 . The indicator post of  claim 12 , wherein the reinforcement means comprises an elongate web portion attached to the elongate sheet. 
   
   
       15 . The indicator post of  claim 14 , wherein the elongate web portion includes a tapered end. 
   
   
       16 . The indicator post of  claim 14 , wherein the elongate sheet is formed of steel. 
   
   
       17 . The indicator post of  claim 1 , wherein the indicator post is a roadside post. 
   
   
       18 . A reinforcement means for an indicator post, the reinforcement means being attached to a driveable portion of the indicator post to reinforce the driveable portion for driving into the ground. 
   
   
       19 . The reinforcement means of  claim 18 , wherein the reinforcement means substantially matches the shape of the drivable portion of the indicator post. 
   
   
       20 . The reinforcement means of  claim 18 , wherein the reinforcement means comprises an elongate web portion.
