Abstract:

The building block of the present invention includes a plurality of pins which are arranged in two rows of unequal length with each projecting from a common surface in a plane perpendicular to such surface and a recessed channel on a surface opposite to such surface in alignment with the longer row and of a depth at least equal to the difference between the two rows. The recessed channel of one row of blocks serves as a guide for sliding in the adjacent upper row in forming a wall of such blocks.
