Safety rail system

Abstract

A post for a temporary safety rail system comprising a base for reversible engagement with a floor, a rail holder to hold a rail in reversibly fixed engagement with the post and a plurality of components which are together operable to adjust the height of the post.

1 . A post for a temporary safety rail system, comprising: a base for reversible engagement with a floor, a rail holder to hold a rail in reversibly fixed engagement with the post and a plurality of components which are together operable to adjust a height of the post. 
     
     
         2 . The post according to  claim 1 , comprising: the plurality of the components have a first component and a second component wherein the first and the second components are slidable about one another to adjust the height. 
     
     
         3 . The post according to  claim 2 , wherein the second component is concentrically slidable within the first component. 
     
     
         4 . The post according to  claim 1 , wherein the rail holder comprises one or more of: a clamp, an aperture, a slot, a bracket, a screw, a bolt, a wing nut. 
     
     
         5 . The post according to  claim 4 , wherein the rail holder defines an aperture to receive a rail and a clamp to reversibly fix the rail in secure engagement with the post. 
     
     
         6 . The post according to  claim 5 , further comprising: a plurality of rail holders which are optionally sited in vertical or horizontal series. 
     
     
         7 . The post according to  claim 1 , further comprising: a stop to restrict downward movement of an upper post component relative to a lower post component wherein the stop passes through an aperture defined by the lower post component and under or through the upper post component. 
     
     
         8 . The post according to  claim 1 , further comprising: a fixture to fix the base to the floor, wherein the post provides support for at least 12 kN load. 
     
     
         9 . A mesh support for a safety rail apparatus, comprising: a first component and a second component which are together operable to adjust a height of a support, a fixing means to reversibly fix the support at a selected height, a cross piece for supporting a mesh and a cross piece holder to hold a cross piece in reversibly fixed engagement with the mesh support. 
     
     
         10 . The mesh support according to  claim 9 , wherein the first and the second components are slidable about one another to adjust the height. 
     
     
         11 . The mesh support according to  claim 10 , wherein the second component is concentrically slidable within the first component. 
     
     
         12 . The mesh support according to  claim 9 , wherein the cross piece holder comprises one or more of: a clamp, an aperture, a slot, a bracket, a screw, a bolt, a wing nut. 
     
     
         13 . The mesh support according to  claim 9 , further comprising: a stop to restrict downward movement of an upper post component relative to a lower post component wherein the stop passes through an aperture defined by the lower post component and optionally under or through the upper post component. 
     
     
         14 . The mesh support according to  claim 9 , wherein the cross piece is removable from the post. 
     
     
         15 . The mesh support according to  claim 9 , wherein the cross piece is integrally formed with the post. 
     
     
         16 . The mesh support according to  claim 9 , further comprising an outrigger element. 
     
     
         17 . A safety rail apparatus, comprising: a post according to  claim 1  and a rail for engagement with the rail holder. 
     
     
         18 . The safety rail apparatus according to  claim 17 , further comprising: a mesh support according to  claim 9 .
