Abstract:
1. A first rectilinear polyhedron toy building block comprising: a top wall; four side walls extending orthogonally away from the top wall to a bottom end of the block, each of the four side walls having an interior surface facing a geometric center of the block and an opposing exterior surface exposed outside of the block; at least one connector extending away from the top wall in a direction opposite the four side walls, the at least one connector including a plurality of partitions, each partition having an interior surface facing a geometric center of the connector and an opposing exterior surface, a free end and an opposing end affixed with the top wall; a bottom wall spaced apart from the top wall and extending across the bottom end of the block within the four side walls; wherein the exterior surface of each of at least two of the plurality of partitions of the at least one connector extends perpendicular with respect to the top wall from the top wall and each of the at least two partitions includes a depression in the perpendicular exterior surface; and wherein the depressions formed in the exterior surfaces of the at least two partitions of the first toy block are different in shape from one another so as to engage with different strengths, one projection on a second toy building block identical to the first toy building block, the second toy building block being selectively orientable on the at least one connector of the first toy building block so as to releasably engage the one projection of the second toy building block with each of the differently shaped depressions.
