Snap lock plastic fencing

Claim 1

A fence assembly comprising a plurality of adjacent pairs of fence sections, each section being formed integrally of plastic and having opposite side edges and upper and lower edges with at least two stake members depending from said lower edge and adapted to be driven simultaneously into the ground; and hinge means for hingedly securing juxtaposed side edges of adjacent pairs of sections, said hinge means including first and second hinge members on each section, one on each side edge of each section, said first hinge member comprising a pair of vertically spaced circular pins providing a vertical axis adjacent one of said side edges, each of said pins being bordered at its upper and lower extremes by shoulders, and said second hinge member comprising a pair of vertically spaced elements each defining a circular opening of a cross-section corresponding to the crosssectional shape and size of said pins on the other of said side edges, each of said second elements being of a vertical height substantially eqUal to the distance between said shoulders, thereby to restrict relative vertical movement of one fence section with respect to the next adjacent fence section when adjacent sections are assembled, said second hinge elements each having an entry throat narrower than its circular opening extending from one side of its opening so that its pin may be forced through the entry slot and into said opening to be releasably snap retained in said opening, said hinge members defining a pivot axis for juxtaposed adjacent sections, and one of said hinge members projecting sidewardly beyond its side edge so that said hinge members may be moved through an arc of as much as 210*, thereby to permit a wide range of configurations for said fence assembly.
