Protecting fence and its positioning member

Abstract

A protecting fence and its positioning member include a protecting fence, a positioning block and a positioning base. The protecting fence is made of foamed engineering plastics by extrusion, with reflective bands. The positioning block has a through hole and an inner surface shaped to match with the protecting fence. The positioning base has a fence combining surface plural holes for being inserted by a bolt to keep the protecting fence and the positioning block fixed together with the positioning base. The fence combining surface has two edge surfaces respectively formed a groove to engage with two edges of the protecting fence. A rear fixing member has a post combining surface employed together with that of the positioning base to wrap the fence post to tightly fix the protecting fence with the fence post by bolts.

1 . A protecting fence and its positioning member comprising:
 said protecting fence being integrally made of engineering plastics by extrusion and provided with plural projective surfaces, a concave surface formed between every two adjacent ones of said projective surfaces, a reflective band integrally formed on each of said projective surfaces, said protecting fence further provided with an upper edge, a bottom edge, and a rectangular slot;   a positioning block provided with a through hole; and   a positioning base provided with a fence combining surface that is bored with plural holes for being inserted through by bolts to enable said protecting fence, said positioning block and said positioning base tightly fixed together, an upper surface and a bottom surface respectively located at a top and a bottom of said fence combining surface, a groove formed between said upper surface and said fence combining surface and between said bottom surface and said fence combining surface respectively for engaging with said upper edge and said bottom edge of said protecting fence, plural through openings located behind said fence combining surface for handily carrying out fastening jobs, a post combining surface formed behind said fence combining surface to correspondingly match with a fence post and bored with plural fastening holes at its two sides respectively, a rear fixing member provided with a post combining surface that is shaped semi-circular to match with said fence post and bored with plural fastening holes at its two sides respectively, said fence post being wrapped by said post combining surfaces of said positioning base and said rear fixing member that are fixed together by bolts inserted through said fastening holes so that said positioning base is completely fixed with said fence post.   
   
   
       2 . The protecting fence and its positioning member as claimed in  claim 1 , wherein an inner surface of said positioning block is shaped semi-circular to match with that of said protecting fence. 
   
   
       3 . The protecting fence and its positioning member as claimed in  claim 1 , wherein said positioning block is provided with a reflective sheet formed on its two sides respectively. 
   
   
       4 . The protecting fence and its positioning member as claimed in  claim 1 , wherein said fence post is wrapped by two said positioning bases that are fixed by said bolts inserted through said fastening holes, so as to built said protecting fence respectively fixed at two sides of said fence post.
