Abstract
Abstract The present invention relates to an improved ornamental integrally molded plastic fence section. The fence section generally includes a pair of substantially parallel stringers with a plurality of pickets formed integral with the stringers. Said pickets being oriented substantially perpendicular to the stringers. Each stringer has a plurality of identical spaced ears formed integral with one end. Each of the ears has a rod aperture extending therethrough. The rod apertures in the ears on one end of a stringer are aligned with rod apertures in ears on the other stringer. A slot is formed in each ear extending from the exterior of the respective ear to the respective aperture. Each slot in each ear on one end of the section is aligned with the other slots in the other ears on that end of the section. A second plurality of supports is formed integral with the other end of each of the stringers. Each of the supports has a height less than the distance between adjacent ears in the first mentioned plurality. Each of the supports has a width less than the width of the slots in the ears. A cylindrical rod is formed integral with the supports on the end of the stringer. Each rod has a diameter slightly less than the diameter of the rod aperture to fit snugly into the respective aligned rod apertures in the ears. The cylindrical rods fit into the ears and the supports pass through the slots to lock adjacent sections to each other by rotating the section relative to each other after each rod has been positioned in its respective rod apertures.
