Barrier

Abstract

A barrier (162, 190) which is constructed from barrier structures (12A, 12B, . . . , 12N) each of which comprises a parallelepiped body made from mesh material with an interior in which are positioned deterrent sections (10, 50, 200, 200X), wherein the bodies are positioned in a succession of overlying horizontal rows which follow a barrier line.

1 . A barrier structure which comprises a parallelepiped body with a first side which is made from a first mesh material, a second side which is made from a second mesh material and which is spaced from and which opposes the first side, an interior between the first side and the second side and a plurality of deterrent sections wherein each deterrent section is made from a third mesh material and is positioned in the interior between the first side and the second side. 
     
     
         2 . A barrier structure according to  claim 1  wherein each deterrent section extends between the first side and the second side. 
     
     
         3 . A barrier structure according to  claim 1  wherein each of at least some of said deterrent sections comprises a respective sheet of said third mesh material which is transverse to the first side and to the second side. 
     
     
         4 . A barrier structure according to  claim 3  wherein said sheet of the third mesh material is selected from the following: a planar sheet of the third mesh material; a sheet of the third mesh material which has a succession of valley formations with intervening peak formations; and a sheet of the third mesh material which is formed into a tubular or partly tubular shape. 
     
     
         5 . A barrier structure according to  claim 1  wherein said plurality of deterrent sections are configured to form a plurality of passages which extend at least partly between the first side and the second side and wherein each passage is bounded, at least partly, by said third mesh material of at least one of said deterrent sections. 
     
     
         6 . A barrier structure according to  claim 1  wherein each of the first mesh material, the second mesh material and the third mesh material, is selected from welded wire mesh and expanded mesh. 
     
     
         7 . A barrier structure according to  claim 1  wherein said plurality of deterrent sections comprises a first array of a first plurality of planar sheets of the third mesh material which planar sheets are parallel to and spaced apart from one another and a second array of a second plurality of planar sheets of the third mesh material which planar sheets are parallel to and spaced and apart from one another, and wherein the first array is transverse to and is engaged with the second array thereby to form a plurality of passages which extend between the first side and the second side. 
     
     
         8 . A barrier structure according to  claim 7  wherein each passage is bounded at least partly by said third mesh material of two of said planar sheets in said first array and by said third mesh material of two of said planar sheets in said second array. 
     
     
         9 . A barrier structure according to  claim 1  wherein each of said deterrent sections respectively comprises an elongate sheet of the third mesh material which has a succession of valley formations with intervening peak formations, and wherein the deterrent sections are configured to form a plurality of passages between the first side and the second side and each of said passages is bounded at least partly by said third mesh material of two adjacent deterrent sections. 
     
     
         10 . A barrier which comprises a plurality of barrier structures, wherein each barrier structure comprises a parallelepiped body which is formed from mesh material and which has an interior and a plurality of deterrent sections which are made from mesh material and which are positioned in the interior, and wherein the barrier structure bodies are arranged abutting one another in a succession of overlying horizontal rows which follow a barrier line. 
     
     
         11 . A barrier according to  claim 10  which includes a plurality of vertically extending supports which are horizontally spaced apart and which are located on the barrier line wherein at least some of the barrier structures are respectively engaged with or respectively secured to said supports. 
     
     
         12 . A barrier according to  claim 11  wherein each said support extends vertically through a number of the barrier structures which overlie one another in a vertical direction and which are in respective horizontally extending rows. 
     
     
         13 . A barrier which comprises a plurality of vertically extending supports which are horizontally spaced apart and which are located on a barrier line, and a plurality of barrier structures, wherein each barrier structure is according to  claim 1 , the barrier structures being arranged abutting one another in a succession of overlying rows of barrier structures each of which follows the barrier line and wherein at least some of said barrier structures are engaged with or fixed to respective supports. 
     
     
         14 . A barrier constructed from pre-formed barrier structures which are made from mesh material with parallelepiped shapes and which have internally located mesh sections and which are arranged abutting one another in a row along a barrier line and in a succession of overlying rows.
