Indicator post

Abstract

An indicator post comprising an elongate sheet of stainless steel is disclosed. The elongate sheet is configured to be resiliency bendable to enable the indicator post to revert upright after an application of a bending force. In other examples, the stainless steel indicator post may be semi-flexible or rigid.

1 . An indicator post comprising an elongate sheet of stainless steel, the elongate sheet configured to be resiliently bendable to enable the indicator post to revert upright after an application of a bending force. 
     
     
         2 . The indicator post of  claim 1 , wherein the stainless steel is an austenitic stainless steel. 
     
     
         3 . The indicator post of  claim 2 , wherein the austenitic stainless steel is 301 type. 
     
     
         4 . The indicator post of  claim 2 , wherein the austenitic stainless steel is 304 type. 
     
     
         5 . The indicator post of  claim 1 , wherein the hardness of stainless steel is selected from a range of any one of:
 less than 310 HV   310-360 HV; or   370-430 HV.   
     
     
         6 . The indicator post of  claim 1 , wherein the elongate sheet has a substantially arcuate sectional profile. 
     
     
         7 . The indicator post of  claim 6 , wherein the arcuate sectional profile has a radius of curvature between 80 mm and 250 mm. 
     
     
         8 . The indicator post of  claim 1 , wherein the width of the elongate sheet is approximately between 40 mm and 140 mm. 
     
     
         9 . The indicator post of  claim 1  wherein the thickness of the elongate sheet is approximately between 0.8 mm and 3.0 mm. 
     
     
         10 . The indicator post of  claim 1 , wherein one end of the elongate sheet is tapered to be driven into the ground. 
     
     
         11 . The indicator post of  claim 10 , further including ground engaging means to resist upward movement of the post after installation into the ground. 
     
     
         12 . The indicator post of  claim 10 , further including an installation depth indicator. 
     
     
         13 . The indicator post of  claim 1 , further including a driveable base portion attached to the elongate sheet. 
     
     
         14 . The indicator post of  claim 13 , wherein the driveable base portion includes a star picket section. 
     
     
         15 . The indicator post of  claim 1 , wherein the indicator post includes a white reflective coating and a retro- reflective sheet portion for configuration as a roadside post. 
     
     
         16 . The indicator post of  claim 1 , wherein the indicator post includes a reflective coating for configuration as a utility marker post. 
     
     
         17 . An indicator post comprising an elongate sheet of stainless steel, the elongate sheet configured to be bendable to enable the indicator post to bend on application of a bending force and then be manually restraightened to a substantially upright position. 
     
     
         18 . The indicator post of  claim 17 , wherein the indicator post has a sectional profile selected from any one of the following:
 C-section,   angle,   box,   top hat,   oval,   trigonal; or   channel.   
     
     
         19 . An indicator post comprising an elongate sheet of stainless steel, the elongate sheet configured to substantially prevent bending of the indicator post on the application of a bending force. 
     
     
         20 . The indicator post of  claim 19 , wherein the indicator post has a sectional profile selected from any one of the following:
 C-section,   angle,   box,   top hat,   oval,   trigonal; or   channel.   
     
     
         21 . The indicator post of  claim 19 , wherein the bending force is from a vehicle impact.
