Modular fence structure

Claim 2

A picket fence panel assembly, comprising: upper and lower vertically spaced inverted U-shape rails each having a bight portion and a plurality of longitudinally spaced non-circular apertures therethrough in substantial vertical alignment, each aperture being characterized by a tab projecting toward an opposite limit of the aperture; a like plurality of vertically disposed tubular pickets cooperatively received by and extending vertically through the aligned apertures, each said picket having vertically spaced wall slots cooperatively nesting said tabs; and, a picket locking fastener interposed in the aperture between each said picket opposite said tab and the opposite limit of the aperture diametrically opposite the tab, said fastener having end surfaces respectively abutting adjacent opposite surfaces of said rail bight portion.

Claim 3

The fence panel assembly according to claim 1 and further including: a post at respective ends of said panel assembly; and, a pair of fence rail end portion supporting ribs secured to confronting surfaces of each said post in cooperative vertically spaced relation.

Claim 4

A picket fence panel assembly, comprising: upper and lower vertically spaced inverted U-shape rails each having a bight portion and a plurality of longitudinally spaced non-circular apertures therethrough in substantial vertical alignment, each aperture being characterized by a rail tab projecting toward an opposite limit of the aperture; a post at respective ends of said panel assembly; rib means on each said Dost for supporting respective end portions of said rails; a like plurality of vertically disposed tubular pickets cooperatively received by and extending vertically through the aligned apertures, each said picket having vertically spaced wall slots cooperatively nesting said tabs; and, picket locking means interposed in one rail aperture between the picket outer surface opposite said tab and the opposite limit of the aperture diametrically opposite the tab and cooperating with said tab for precluding movement of said pickets with respect to said rail, said picket locking means including: an inverted L-shaped member having a foot portion overlying the rail bight portion adjacent said one aperture and having a leg substantially defining a V-shape and having one leg of the V-shape underlying the rail bight portion in opposition to said foot portion.

Claim 5

A picket fence panel assembly, comprising: upper and lower vertically spaced inverted U-shape rails each having a bight portion and a plurality of longitudinally spaced non-circular apertures therethrough in substantial vertical alignment, each aperture being characterized by a rail tab projecting toward an opposite limit of the aperture; a post at respective ends of said panel assembly; rib means on each said Dost for supporting respective end portions of said rails; a like plurality of vertically disposed tubular pickets cooperatively received by and extending vertically through the aligned apertures, each said picket having vertically spaced wall slots cooperatively nesting said tabs; and, picket locking means interposed in one rail aperture between the picket outer surface opposite said tab and the opposite limit of the aperture diametrically opposite the tab and cooperating with said tab for precluding movement of said pickets with respect to said rail, said picket locking means including: an inverted L-shaped member having a foot portion overlying the rail bight portion adjacent said one aperture and having a leg substantially defining a V-shape and having one leg of the V-shape underlying the rail bight portion in opposition to said foot portion.

Claim 6

The picket fence panel assembly according to claim 3 in which said L-shaped member is formed from spring steel material.

Claim 7

The picket fence panel assembly according to claim 3 in which said rib means comprises: a rectangular member having an orthogonal end surface abutting said post and having an opposite arcuate end surface.
