  • Patent number: 4275540
    Abstract: A plastic simulated brick wall free standing section adapted to be connected to other sections to form a brick wall.The plastic sections are of a open box-like structure having a simulated brick wall front. The sections are comprised of an even number of staggered tiers in which the tiers alternate in length to provide overlapping or overhanging bricks staggered between adjacent tiers one-half brick. In this fashion the sections may be inverted with respect to one another and interlocked and connected together by a pin passing through the overhanging end sections to lock the intertwined and interlocked sections together. A cap stone is provided at both the top and the bottom and extends forwardly from the front brick simulated wall a short distance so that when the sections are placed on the ground they provide a greater degree of stability while providing a pleasing appearance through the top cap stone.
