Fence structure

Abstract

A security fence structure including posts, rails, fence gratings, mounting brackets, fence clips and fasteners is easily assembled in the field. The rails are secured to the post by mounting brackets and fasteners, and the fence grating secured to the rails by means of the fence clips and fasteners. The fence gratings, in conjunction with the mounting brackets, fence clips and fasteners are resistant to climbing.

1 . A fence structure comprising:
 one or more post having one or more holes at predetermined locations down each opposing side;   one or more mounting brackets having a pivot, a horizontally oriented slot and a vertically oriented slot,
 said one or more mounting brackets fastened about said vertically oriented slot to said post via at least one of said one or more holes, 
 said pivot, horizontally oriented slot and said vertically oriented slot defining a relative orientation; 
   one or more rails fastened about at least one end to said one or more mounting brackets about their respective horizontally oriented slot;   one or more fence grating having a plurality of vertical members;   one or more fence clips having an outer face, an inner face, and two tapered edges at opposing ends, said tapered edges extending the length of said opposing ends and from said inner face to said outer face,   wherein said one or more fence clips are fastened to said one or more rails, capturing at least two of said plurality of vertical members, said two tapered edges residing on either side of said at least two of said plurality of vertical members and proximate to their corresponding one or more rails, and   said relative orientation providing differential freedom of movement for assembly of said fence structure in a horizontal, vertical, and angular orientation.   
     
     
         2 . The fence structure of  claim 1 , wherein at least one of said one or more posts have horizontally aligned holes at two or more predetermined locations down adjacent sides to accept fastening of at least one of said one or more mounting brackets. 
     
     
         3 . The fence structure of  claim 2 , further comprising a first mounting bracket and a second mounting bracket of said one or more mounting brackets mounted to said adjacent sides of said one or more posts. 
     
     
         4 . The fence structure of  claim 3 , further comprising a first fence grating and a second fence grating of said one or more fence gratings arranged to form an angle selected from the group consisting of acute, obtuse, reflex, 90 and 180. 
     
     
         5 . The fence structure of  claim 1 , wherein said one or more mounting brackets comprise a vertical placement tolerance of about +/−2 inches. 
     
     
         6 . The fence structure of  claim 1 , wherein said two tapered edges provide zero clearance to each said corresponding said two or more rails. 
     
     
         7 . The fence structure of  claim 1 , wherein said one or more fence clips comprise a cross section of a C-shaped or a W-shaped, having said tapered edges oriented vertically. 
     
     
         8 . The fence structure of  claim 1 , wherein said one or more fence clips comprise a through hole about a center portion of said fence clip. 
     
     
         9 . The fence structure of  claim 8 , wherein said through hole is a square. 
     
     
         10 . The fence structure of  claim 1 , wherein at least one of said one or more posts are a terminal posts, include an overhang portion, a cap, a cross section of about two inches by four inches or a combination thereof. 
     
     
         11 . The fence structure of  claim 1 , wherein at least one of said two or more rails comprise a through hole at each end. 
     
     
         12 . The fence structure of  claim 11 , wherein said through hole at each end of said one or more rails is square. 
     
     
         13 . The fence structure of  claim 1 , wherein at least one of said one or more rails comprise a series of through slots about their lengths. 
     
     
         14 . The fence structure of  claim 1 , wherein said through slots are fabricated to accept a fence clip comprising opposing ends having an end tab providing resistance to rotation. 
     
     
         15 . A fence structure comprising:
 one or more posts each comprising horizontally aligned paired holes at two or more predetermined locations down each opposing side;   one or more T-shape mounting brackets comprising
 a horizontally oriented slot and 
 two vertically oriented parallel slots, said horizontally oriented slot and said two vertically oriented parallel slots defining a relative orientation, 
 said one or more T-shape mounting brackets fastened about said two vertically oriented parallel slots to said one or more posts at said horizontally aligned paired holes; 
   one or more rails fastened about at least one end to said one or more T-shape mounting brackets about their respective horizontally oriented slot and between each of said one or more posts;   one or more fence grating comprising a plurality of vertical members; and   one or more fence clips comprising an outer face, an inner face, and two tapered edges at opposing ends, said tapered edges extending the length of said opposing ends and from said inner face to said outer face,   wherein each of said one or more fence clips are fastened to said one or more rails, capturing at least two of said plurality of vertical members, said two tapered edges residing on either side of said at least two of said plurality of vertical members and residing proximate to their corresponding two or more rails, and   said relative orientation of said horizontally oriented slot and said two vertically oriented parallel slots provide differential freedom of movement for assembly of said fence structure in both a horizontal and vertical orientation.   
     
     
         16 . The fence structure of  claim 15 , wherein one surface of said one or more rails is co-planer with one surface of said two or more posts. 
     
     
         17 . The fence structure of  claim 15 , wherein said one or more fence grating overlaps at least one of said one or more posts. 
     
     
         18 . The fence structure of  claim 15 , wherein at least one of said one or more posts have horizontally aligned paired holes at two or more predetermined locations down adjacent sides to accept fastening of said at least one of said one or more mounting brackets. 
     
     
         19 . The fence structure of  claim 18 , further comprising a first mounting bracket and a second mounting bracket of said one or more mounting brackets mounted to said adjacent sides of said one or more posts. 
     
     
         20 . The fence structure of  claim 19 , further comprising a first fence grating and a second fence grating of said one or more fence gratings arranged to form an angle of about 90 degrees or 270 degrees.
