Triangle based interconnecting block set
First Claim
1. A block set comprising a plurality of blocks each having a top side, a bottom side and a side surface extending between said top and bottom side, at least one projecting means extending from the top side of each of said blocks and receiving means on the bottom side of each of said blocks to receive a projecting means extending from the top side of another one of said blocks to interconnect and hold together a pair of said blocks in predetermined alignments, a subset of blocks each having the shape of a geometric figure consisting of a plurality of contiguous, congruent, equilateral triangles when viewed in a sectional plane perpendicular to said side surface, said projecting means and said receiving means being arranged so that the blocks of said subset can be interconnected with only one of the contiguous equilateral triangles in each block of an interconnected pair of blocks, overlapping and held in fixed alignment by said projecting means and said receiving means.

Abstract
In a set of interconnecting blocks, each provided with a male top side designed to interconnect with a female bottom side, the blocks are shaped in the form of equilateral triangles or combinations of equilateral triangles such as parallelograms, trapezoids, and hexagons. Studs are provided on the male sides of the blocks which mate with triangular openings on the female sides of the blocks and when the blocks are interconnected, they are frictionally held together. The set includes a transitional module to interconnect with square based blocks of the prior art.

12. A block set comprising a first set of blocks interconnected in either of two angular orientations displaced 90 degrees from each other, a second set of blocks interconnectable in any of three angular orientations displaced 60 degrees from each other, the blocks of said first set not being directly interconnectable with the blocks of said second set, a transition module block having a male side comprising a set of studs and a female side comprising a shaped aperture, the set of studs being shaped and arranged to interconnect with the blocks of one of said first and second sets and said shaped aperture being shaped and arranged to interconnect with the blocks of the other one of said first and second sets.
