  • Patent number: 5134817
    Abstract: A landscape border brick system includes a plurality of bricks and a plurality of connectors for interconnecting bricks which are placed end to end. Each brick has connector recesses formed in its opposite ends for receiving the connectors. The connector recesses are formed in the bottom surface of the brick which rests on the ground, so a brick can be lifted off its connectors and replaced without disturbing adjacent bricks. The system includes two basic kinds of bricks, main bricks and secondary bricks. The main or angled bricks have a pair of leg portions which intersect at an angle, preferably 30 degrees, to form a generally V-shaped configuration when viewed from above. The secondary bricks are straight and may be interposed between the main bricks in any desired arrangement. Both the main bricks and the secondary bricks may be provided in varying lengths.
