Composite masonry block

A structure, said structure comprising one or more courses, each of said courses comprising one or more masonry blocks, at least one of said masonry blocks comprising (a) a front surface and a back surface, a top surface and bottom surface, and first and second sides, said first side having a first inset wherein said first inset spans from said block top surface to said block bottom surface, said second side having a second inset, wherein said second inset spans from said block top surface to said block bottom surface, and (b) a protrusion on said block top surface wherein said block protrusion is configured to mate with the inset of one or more adjacently positioned blocks and, first and second legs, said first leg extending from said block first side surface and said second leg extending from said block second side surface wherein said first and second legs comprise front surfaces, said leg front surfaces configured to extend towards said block front surface as said first and second legs extend away from said block.

A masonry block comprising a front surface, a back surface, a top surface and bottom surface, and first and second sides, said first side having a first inset wherein said first inset extends from said block top surface to said block bottom surface, said second side having a second inset wherein said second inset extends from said block top surface to said block bottom surface, said block comprising a protrusion on one of said top or bottom surfaces, said protrusion being configured to mate with an inset of one or more adjacently positioned blocks, said protrusion and insets having relative sizes and shapes adapted to permit relative rotation of the protrusion and the inset with which it is mated, whereby serpentine walls may be constructed from a plurality of such blocks.

A masonry block comprising a front surface and a back surface, a top surface and bottom surface, and first and second sides, said first side having a first inset wherein said first inset spans from said block top surface to said block bottom surface, said second side having a second inset, wherein said second inset spans from said block top surface to said block bottom surface, a protrusion on one of said block top or bottom surfaces, and, first and second anchoring legs, said first leg extending from said block first side and said second leg extending from said block second side, said protrusion and insets having relative sizes and shapes adapted to permit relative rotation of the protrusion and the inset with which it is mated, whereby serpentine walls may be constructed from a plurality of such blocks.

A retaining wall structure, said retaining wall structure comprising one or more courses, each of said courses comprising one or more masonry blocks, each of said blocks comprising a front surface and a back surface, a top surface and bottom surface, and first and second sides, said first side having a first inset wherein said first inset extends from said block top surface to said block bottom surface, said second side having a second inset, wherein said second inset extends from said block top surface to said block bottom surface, a protrusion on one of said block top or bottom surfaces, wherein said protrusion is configured to mate with an inset of one or more adjacently positioned blocks, said protrusion and insets having relative sizes and shapes adapted to permit relative rotation of the protrusion and the inset with which it is mated, whereby serpentine walls may be constructed from a plurality of such blocks.

A masonry block comprising a front surface, a back surface, a top surface and bottom surface, and first and second sides, said first side having a first inset wherein said first inset extends from said block top surface to said block bottom surface, said second side having a second inset wherein said second inset extends from said block top surface to said block bottom surface, said block comprising a protrusion on one of said top or bottom surfaces, said protrusion being configured to mate with an inset of one or more adjacently positioned blocks, said protrusion and insets having relative sizes and shapes adapted to permit related rotation of the protrusion and the inset with which it is mated, whereby serpentine walls may be constructed from a plurality of such blocks, wherein said blocks are capable of being used in a landscape structure without pins.
