Patent ID: 6996945

Claim:
A block system, comprising: a plurality of blocks, each block having a top surface, a bottom surface, a front surface, a back surface, one or more end surfaces, a height defined by a distance from said top surface to said bottom surface, and one or more apertures, each aperture being generally grooveless, each aperture extending from said top surface through said block to said bottom surface and having a guiding portion and a connecting portion, said guiding portion having a length of about one fourth said height of said block and having a surface diameter and an ending diameter wherein said surface diameter is a diameter of said aperture at said bottom surface of said block and said ending diameter of said guiding portion is equal to a diameter of said connecting portion, said surface diameter being greater than said ending diameter such that said guiding portion tapers from said surface diameter to said ending diameter, and said connecting portion of each said aperture having a generally uniform diameter equal to said ending diameter of said guiding portion, and wherein said top surface of said block is substantially flat such that when a top surface of a first block is interconnected with a bottom surface of a second block, the guiding portion of said aperture in the bottom surface of the second block remains substantially void of the top surface of said first block; a plurality of hollow pegs, each said hollow peg having an internal cavity defined by an internal diameter and an outer diameter slightly smaller than said diameter of said apertures in said blocks, and each said hollow peg being generally slitless; and a means for interconnecting a first block with a second block using a first hollow peg and a second hollow peg, wherein said first hollow peg is inserted in one said aperture of said first block such that a portion of said first hollow peg extends above said top surface of said first block and into one said aperture of said second block, thereby creating a vertical shaft through said aperture of said first block and said aperture of said second block, and wherein said second hollow peg is inserted in said one said aperture of said second block such that said second hollow peg is aligned with and abuts said first hollow peg.
