Fence and its fixing device

Abstract

A fence is made integral of plastic foam material by injecting molding, having an inner shock-enduring layer contained in the interior, and shaped corrugated to have a plurality of lengthwise convex ridges and lengthwise concave recesses alternately connected with each other, with a light reflecting strip or dot adhered on each ridge. The fixing device of the fence includes a fixing base and a fixing block, and the fixing base is provided with a fence-contacting surface for combining with the fence. The fixing block is fixed with a bolt on a front surface of the fence at the spot where the fence is to be fixed with the vertical post, with the fixing base placed behind the fence. Thus the fence can be installed stably at two sides of a road,

1 . A fence made integral of plastic foam material and having a corrugated shape with a plurality of lengthwise convex ridges and a plurality of lengthwise concave recesses alternately connected each other, a light reflecting strip formed integral on each said ridge to provide said fence with a light reflecting function; an inner shock-enduring layer contained in said fence during its injecting molding so that said fence is substantively elastic, and not to be easily broken or rifted to have a safety function for protecting persons or cars.  
   
   
       2 . A fence and its fixing device comprising: 
 a fence provided with an upper lengthwise end, a lower lengthwise end and a plurality of boltholes;    a fixing block bored with a through hole;    a fixing base having a fence contacting surface, a hole formed in said fence contacting surface for a blot to tighten said fixing block and said fence with said fixing base, said fence contacting surface having an upper edge and a lower edge; said fixing base further provided with a side through hole and a post contacting surface for tightly combining with a post;    said fixing base firstly fastened with said post with a bolt, said fence then fixed with said fixing base so that said post, said fixing base and said fence may be tightly combined all together.    
   
   
       3 . A fence and its fixing device comprising: 
 a fence provided with an upper lengthwise end, a lower lengthwise end and a plurality of boltholes;    a fixing block bored with a through hole;    a fixing base provided with a fence contacting surface, said fence contacting surface having a hole for a bolt to pass through to tighten said fixing block and said fence with said fixing base, said fence contacting surface provided with an upper edge and a lower edge, said fixing base further having a side through hole and a post hole for a post to vertically pass through, an upper fixing ring fitted around an upper portion of said post and a lower fixing ring fitted around a lower portion of said post, a bolt engaging through said upper and said lower fitting ring to tightly fix said upper and said lower fitting ring to said post for fixing tightly said fixing base with said post;    said fixing base firstly fixed with said post with said bolt, said fence then fixed with said fixing base so that said fence, said fixing base and said post may be tightly combined all together.    
   
   
       4 . The fence and its fixing device as claimed in  claim 2 , wherein said fixing block is provided with an inner surface conformed to the shape of the surface of said fence so that said fixing block may contact closely with said post.  
   
   
       5 . The fence and its fixing device as claimed in  claim 2 , wherein said fixing block has a light reflecting dot attached respectively on its two sides.  
   
   
       6 . The fence and its fixing device as claimed in  claim 2 , wherein said fixing base is provided with a groove between said upper edge and said fence contacting surface, and between said lower edge and said contacting surface, so said upper end and said lower end of said fence may fit in said grooves first for convenience of subsequent assembling work.  
   
   
       7 . The fence and its fixing device as claimed in  claim 2 , wherein said post contacting surface of said fixing base is provided with a rectangular hole and two sidewalls so that said fixing base may be corrected in its location to said post so as to cope with an error of the height of said post after buried in the ground, and may be combined with said post smoothly and accurately.  
   
   
       8 . The fence and its fixing device as claimed in  claim 3 , wherein said fixing block is provided with an inner surface conformed to the shape of the surface of said fence so that said fixing block may contact closely with said post.  
   
   
       9 . The fence and its fixing device as claimed in  claim 3 , wherein said fixing block has a light reflecting dot attached respectively on its two sides.  
   
   
       10 . The fence and its fixing device as claimed in  claim 3 , wherein said fixing base is provided with a groove between said upper edge and said fence contacting surface, and between said lower edge and said contacting surface, so said upper end and said lower end of said fence may fit in said grooves first for convenience of subsequent assembling work.
