US Patent 9528263 Self-aligning interlocking construction blocks

A self-aligning block system is disclosed having a series of block formations wherein the blocks comprise predefined polygonal shaped channels for insertion of a uniformly shaped polygonal peg. Insertion of a peg between adjacent channels will drive uneven blocks into alignment and hold the blocks without the need of mortar. Walls may be created by end-to-end stacking of linear blocks and half blocks in staggered or parallel columns to create internal walls and corners within a wall by addition of corner blocks and half blocks without offsetting the progression of the outer wall. Addition of half blocks into wall progression may be implemented to reset the progression of inner and outer walls after corner formation.
