Fence rail device

Abstract

A fence rail device includes a rail elongated between a first end and a second end. The rail has an outer wall having a top section, a pair of side sections, and a bottom section defining a hollow interior. A slot extends through the bottom section to define a pair of lateral bottom edges. A top cross wall is spaced from the top section of the outer wall to define an upper interior space and a bottom cross wall is positioned between the top cross wall and the bottom section to define a middle interior space and a lower interior space. Each of a pair of lower walls extends between the bottom section and the bottom cross wall proximate to a respective one of the side sections. Each of a pair of medial walls extends between the bottom cross wall and the top cross wall.

I claim: 
     
         1 . A fence rail device comprising:
 a rail, said rail having a first end and a second end, said rail being elongated between said first end and said second end, said rail comprising an outer wall defining a hollow interior extending between said first end and said second end, said outer wall having a top section, a pair of side sections, and a bottom section, said side sections being parallel to each other, said side sections being substantially planar;   a slot extending through said bottom section between said first end and said second end to define a pair of lateral bottom edges;   a pair of cross walls, each of said cross walls being planar, each of said cross walls extending between said side sections, said pair of cross walls including a top cross wall and a bottom cross wall, said top cross wall being spaced from said top section of said outer wall to define an upper interior space within said outer wall, said bottom cross wall being positioned between said top cross wall and said bottom section to define a middle interior space above said bottom cross wall and a lower interior space under said bottom cross wall;   a pair of lower walls, each of said lower walls being coupled to and extending between said bottom section and said bottom cross wall, each of said lower walls being positioned proximate to a respective one of said side sections; and   a pair of medial walls, each of said medial walls being coupled to and extending between said bottom cross wall and said top cross wall.   
     
     
         2 . The device of  claim 1 , further comprising a distance between said medial walls being less than a distance between said lower walls. 
     
     
         3 . The device of  claim 1 , further comprising a pair of upper grooves, each of said upper grooves extending into a respective one of said side sections of said outer wall of said rail. 
     
     
         4 . The device of  claim 3 , further comprising each of said side sections having a constant thickness wherein each of said upper grooves defines a corresponding upper interior ridge within said hollow interior. 
     
     
         5 . The device of  claim 4 , further comprising each of said upper interior ridges being positioned within said medial interior space adjacent to said top cross wall 
     
     
         6 . The device of  claim 1 , further comprising a pair of lower grooves, each of said lower grooves extending into a respective one of said side sections of said outer wall of said rail. 
     
     
         7 . The device of  claim 6 , further comprising each of said side sections having a constant thickness wherein each of said lower grooves defines a corresponding lower interior ridge within said hollow interior. 
     
     
         8 . The device of  claim 7 , further comprising each of said lower interior ridges being positioned within said lower interior space adjacent to said bottom cross wall. 
     
     
         9 . The device of  claim 1 , further comprising each of said lateral bottom edges extending inwardly from a base of an associated one of said lower walls defining a pair of spaced lips extending between said first end and said second end of said rail. 
     
     
         10 . The device of  claim 1 , further comprising a distance between said top cross wall and said top section being less than a distance between said bottom wall and said bottom section. 
     
     
         11 . A fence rail device comprising:
 a rail, said rail having a first end and a second end, said rail being elongated between said first end and said second end, said rail comprising an outer wall defining a hollow interior extending between said first end and said second end, said outer wall having a top section, a pair of side sections, and a bottom section, said side sections being parallel to each other, said side sections being substantially planar;   a slot extending through said bottom section between said first end and said second end to define a pair of lateral bottom edges;   a pair of cross walls, each of said cross walls being planar, each of said cross walls extending between said side sections, said pair of cross walls including a top cross wall and a bottom cross wall, said top cross wall being spaced from said top section of said outer wall to define an upper interior space within said outer wall, said bottom cross wall being positioned between said top cross wall and said bottom section to define a middle interior space above said bottom cross wall and a lower interior space under said bottom cross wall;   a pair of lower walls, each of said lower walls being coupled to and extending between said bottom section and said bottom cross wall, each of said lower walls being positioned proximate to a respective one of said side sections, each of said lateral bottom edges extending inwardly from a base of an associated one of said lower walls defining a pair of spaced lips extending between said first end and said second end of said rail; and   a pair of medial walls, each of said medial walls being coupled to and extending between said bottom cross wall and said top cross wall, a distance between said medial walls being less than a distance between said lower walls;   a pair of upper grooves, each of said upper grooves extending into a respective one of said side sections of said outer wall of said rail;   a pair of lower grooves, each of said lower grooves extending into a respective one of said side sections of said outer wall of said rail;   each of said side sections having a constant thickness wherein each of said upper grooves defines a corresponding upper interior ridge within said hollow interior and each of said lower grooves defines a corresponding lower interior ridge within said hollow interior, each of said upper interior ridges being positioned within said medial interior space adjacent to said top cross wall, each of said lower interior ridges being positioned within said lower interior space adjacent to said bottom cross wall; and   a distance between said top cross wall and said top section being less than a distance between said bottom wall and said bottom section.
