  • Patent number: 5601278
    Abstract: A picket fence includes a pair of substantial vertical posts, a top and bottom rail members supported by each of the posts, and pickets attached to the top and bottom rail members. The posts, rails and pickets are all made of the polyvinyl material. The pickets are attached to the rails by cleats engaging keyhole shaped slots in the pickets. In one embodiment of the invention, the keyhole shaped slots extend in opposite directions, so that the rails must be moved relative to the pickets in order to secure the pickets to the rails. Accordingly, the pickets cannot be removed from the rails without first removing the rails from the posts. In another embodiment of the invention, keyhole slots extend in the same direction, and a locking arm extends from the cleats into the narrower portion of the keyhole slot. Accordingly, in order to remove the picket from the rail, both the top and bottom portions of the picket must first be deflected slightly and the picket must then be forced downwardly.

  • Patent number: 5362030
    Abstract: The present invention relates to a single post module which provides all the connections needed to make a fence. This module can be assembled, by unskilled persons, with other like modules to form fence posts by end-to-end assembly and connection. Each module in a post has a connector to which hollow fence rails or panel sleeves may be attached. Fence panels thus formed have a post at each end. Each module in every post has projecting hinge fins which, when overlapped with the fins of modules in similar posts, permits joining of up to four posts and their fence panels by making a pin connection at the common axis through the holes in the hinge fins at that location. This permits construction of a fence which can branch into as many as three new fences at any location.
