  • Patent number: 4586302
    Abstract: A construction-type support system comprises a plurality of at least generally parallelopipedal blocks each having top and bottom walls formed with complementary vertical projections and recesses. These blocks fit together with the projections interengaged and preventing relative horizontal shifting. The blocks are all of the same height and depth, but are of a width that is a whole-number multiple of a predetermined width. Thus normally some of the blocks are substantially cubical and the others are rectangular and twice the width as the cubical blocks. The top and bottom walls of the rectangular blocks each have two such respective projections and recesses. When fitted together and stood on a flat surface, a system of such blocks is extremely stable. They can be stacked up in a pyramid or tower, or can form a wall.
