Patent ID: 7134646

Claim:
A privacy fence system comprising: a plurality of ground poles providing vertical structural support into the ground; at least one cross-rail providing horizontal structural support; a plurality of cross-rail mounting holes in each end of each said cross-rail for mounting said cross-rail upon said ground poles; whereby said cross-rail is mounted upon said ground poles using fasteners extending through cross-rail mounting holes; a plurality of pickets substantially blocking visibility, said pickets having upper and lower ends; and a plurality of cross-rail lips protruding perpendicularly from each said cross-rail for mounting said pickets upon said cross-rail; whereby each said picket is mounted upon said cross-rail using a fastener extending through a mounting hole in a corresponding cross-rail lip; said cross-rail lips being unitarily formed as a single piece with said cross-rail and defining a plurality of notches between said cross-rail lips for receiving said pickets, said cross-rail lips being spaced uniformly along the length of said cross-rail; wherein, when said pickets are mounted upon said cross-rail lips, a plurality of gaps are defined between adjacent pickets; said gaps permitting angular movement of said pickets within said notches, enabling said upper ends of said pickets to maintain a straight line fence height over non-level terrains, and said gaps facilitating air to flow between said pickets.
