Cut-Resistant Security Fence

Abstract

A cut-resistant fence panel and method of securing a protected site are provided that preserves some ability to see through the fence and have air-flow through the fence.

What is claimed: 
     
         1 . A method of securing a protected side of a substantially quadrilateral grade-level surface from an unprotected side of the grade-level surface comprising:
 resisting horizontal motion across the grade-level surface;   resisting motion up a surface defined vertically from the unprotected side of the grade-level surface;   providing visibility and air-flow across the grade-level surface; and   restricting cutting tools from insertion into a volume defined above the grade-level surface.   
     
     
         2 . A device for securing a protected side of a substantially quadrilateral grade-level surface from an unprotected side of the grade-level surface comprising:
 means for resisting horizontal motion across the grade-level surface;   means for resisting motion up a surface defined vertically from the unprotected side of the grade-level surface;   means for providing visibility and air-flow across the grade-level surface; and   means for restricting cutting tools from insertion into a volume defined above the grade-level surface.   
     
     
         3 . A device as in  claim 2 , wherein said means for resisting horizontal motion comprises a wire-mesh panel having horizontal wires and vertical wires, wherein the vertical wires are spaced wider than the horizontal wires. 
     
     
         4 . A device as in  claim 3 , wherein said means for resisting horizontal motion further comprises a further wire-mesh panel having horizontal wires and vertical wires, wherein the horizontal wires are spaced wider than the vertical wires. 
     
     
         5 . A device as in  claim 2 , wherein said means for resisting motion up a surface comprises a wire-mesh panel having horizontal outer wires spaced at a distance below about ½ inch. 
     
     
         6 . A device as in  claim 2 , wherein said means for providing visibility and air-flow across the grade-level surface comprises a set of tubular members positioned substantially normal to said vertical surface. 
     
     
         7 . A device a in  claim 2 , wherein said means for restricting cutting tools from insertion into a volume defined above the grade-level surface comprises a set of tubular members positioned substantially normal to said vertical surface with a spacing and maximum internal width of less than about two inches. 
     
     
         8 . A fence panel for securing a protected side of a substantially quadrilateral grade-level surface from an unprotected side of the grade-level surface comprising:
 at least one wire-mesh panel; and   a set of tubular members positioned substantially normal to said at least one wire-mesh panel.   
     
     
         9 . A fence panel as in  claim 8 , wherein said at least one wire-mesh panel includes horizontal outer wires spaced at a distance below about ½ inch. 
     
     
         10 . A device as in  claim 8 , wherein said set of tubular members has a spacing and maximum internal width of less than about two inches. 
     
     
         11 . A fence panel as in  claim 8 , further comprising a protected side wire-mesh panel connected to said set of tubular members. 
     
     
         12 . A fence panel as in  claim 8 , further comprising a protected side wire-mesh panel welded to said set of tubular members. 
     
     
         13 . A fence panel as in  claim 8 , wherein at least some of the set of tubular members are welded to the at least one wire-mesh panel. 
     
     
         14 . A fence panel as in  claim 8 , further comprising a second wire-mesh panel, welded to said set of tubular members. 
     
     
         15 . A fence panel as in  claim 8 , wherein at least some of the tubular members are connected together. 
     
     
         16 . A fence panel as in  claim 8 , wherein at least some of the tubular members are welded together. 
     
     
         17 . A method of making a fence at a pre-designated fence location, the fence location having a protected side and an unprotected side, the fence comprising:
 providing a set of tubular members;   connecting the set of tubular members to a protected side of a welded wire-mesh panel;   transporting the welded unprotected side welded wire-mesh panel, connected to the set of tubular members, to the fence location; and   erecting the fence panel at the fence location.   
     
     
         18 . A method as in  claim 17 , further comprising welding said set of tubular members together connecting an unprotected side welded wire-mesh panel to the set of tubular members. 
     
     
         19 . A method as in  claim 17 , wherein said connecting an unprotected side welded wire-mesh panel to the set of tubular members comprises welding. 
     
     
         20 . A method as in  claim 17  wherein said connecting an unprotected side welded wire-mesh panel to the set of tubular members occurs after said transporting.
