Patent ID: 7690629

Claim:
A modular rail and post fence system which comprises: a plurality of rail assemblies, each rail assembly formed from a pair of elongated rail panels, each rail panel comprising a pair of sidewalls joined at an obtuse angle to form an obtuse angled edge extending the length of said rail panel and each sidewall having a joining edge extending the length of said rail panel; wherein each said joining edge of one of each said pair of rail panels interlockably engages a respective said joining edge of the other of said pair of rail panels, wherein said pair of rail panels are joined together to form a rail assembly having a cross-section generally shaped as a non-equiangular rhombus comprising a pair of opposed angles defined by opposed said obtuse angled edges of said pair of rail panels and a pair of opposed acute angles, each acute angle being defined between one said sidewall of one of said pair of rail panels and a respective joined sidewall of the other of said pair of rail panels, and wherein said sidewalls of each said rail panel resiliently flex about said obtuse angled edge of said rail panel to allow said opposed obtuse angled edges to be flexed toward each other; and a plurality of elongated posts, each post having at least one longitudinal recess comprising a pair of opposed longitudinally-extending sides having at least one pair of opposed notches, wherein one of said pair of notches is disposed in one of said sides of said recess and the other of said pair of notches is disposed in the other side of said recess opposite said one recess; wherein each longitudinal end of each said rail assembly is received in a pair of said notches of a respective one of said posts, such that in an assembled position, a distance between said pair of opposed obtuse angled edges of said rail assembly is greater than a distance between said sides of said longitudinal recess of said post, and wherein in an installation position, said longitudinal end of said rail assembly is perpendicularly inserted into said longitudinal recess of said post such that said opposed obtuse angled edges of said rail assembly are flexed toward each other, and wherein in said assembled position, said rail assembly is moved so that said pair of opposed obtuse angled edges of said rail assembly are resiliently expanded and received in a respective said pair of notches of said post.
