Support for supporting cable net, and security fence using the same

Abstract

In a support installed at a security fence which includes a fence dividing a certain area into a security area and a non-security area and a cable net installed at an upper side of the fence, there is provided a support for a security fence, comprising a first part which has a length in a first direction and is fixed at the fence, with the first direction corresponding to a perpendicular direction of the fence; a second part which is extended in a second direction crossing the first direction, while getting further from the cable net; and a third part which is extended in a third direction crossing the second direction, while getting closer to the cable net.

1 . In a support installed at a security fence which includes a fence dividing a certain area into a security area and a non-security area and a cable net installed at an upper side of the fence, a support for a security fence, comprising: 
 a first part which has a length in a first direction and is fixed at the fence, with the first direction corresponding to a perpendicular direction of the fence;    a second part which is extended in a second direction crossing the first direction, while getting further from the cable net; and    a third part which is extended in a third direction crossing the second direction, while getting closer to the cable net.    
   
   
       2 . The support of  claim 1 , wherein the center axes of the first part, the second part and the third part are positioned at the same plane.  
   
   
       3 . The support of  claim 2 , wherein an angle between the first part and the second part is an obtuse angle.  
   
   
       4 . The support of  claim 1 , wherein said first part, said second part and said third part are integral with each other.  
   
   
       5 . The support of  claim 4 , wherein said first part, said second part and said third part are connected with each other and are formed in a curve shape.  
   
   
       6 . The support of  claim 1 , wherein the length of said second part is shorter than the length of said third part.  
   
   
       7 . The support of  claim 6 , wherein said first part, said second part and said third part are formed in a pipe shape or a rod shape.  
   
   
       8 . The support of  claim 6 , wherein said first part, said second part and said third part have circular or rectangular cross sections, respectively.  
   
   
       9 . The support of  claim 6 , wherein said first part, said second part and said third part are formed in plate shapes, respectively.  
   
   
       10 . A security fence, comprising: 
 a fence which divides a certain area into a security area and a non-security area;    a cable net which is installed at an upper side of the fence; and    a support which is fixed at the fence and supports the cable net,    wherein said support includes: 
 a first part which has a length in a first direction and is fixed at the fence, with the first direction corresponding to a perpendicular direction of the fence;  
 a second part which is extended in a second direction crossing the first direction, while getting further from the cable net; and  
 a third part which is extended in a third direction crossing the second direction, while getting closer to the cable net.  
   
   
   
       11 . The fence of  claim 10 , wherein said fence includes a net, and poles for supporting the net.  
   
   
       12 . The fence of  claim 11 , wherein said net is formed of an optical cable.  
   
   
       13 . The fence of  claim 10 , wherein said third part of the support is extended downward on the fence toward the security area.  
   
   
       14 . The fence of  claim 10 , wherein said fence is formed of a block assembly such as bricks or cements.  
   
   
       15 . The fence of  claim 14 , wherein said cable net is installed over the fence.  
   
   
       16 . The fence of  claim 14 , wherein an end of the third part of the support is positioned at an extended line of a perpendicular direction axis of the fence.  
   
   
       17 . The fence of  claim 10 , further comprising: 
 a Y-shaped support member installed over the fence; and    a barbed wire which is installed at the support member in a spiral shape or a line shape.    
   
   
       18 . The fence of  claim 17 , wherein said third part of the support is extended into the non-security area, crossing a perpendicular direction axis of the fence.  
   
   
       19 . The fence of  claim 10 , wherein the length of said second part is shorter than the third part of the support.
