Abstract
The invention is a composite masonry block having a front surface and a back surface which are adjoined by first and second side surfaces, as well as a top surface and a bottom surface. Each of the side surfaces has an inset extending from the block top surface to the block bottom surface. The block top surface has one or more protrusions positioned adjacent the first and second insets on the block top surface. The block also has a protrusion which has an angled side wall, the angle being at least about 20.degree. from vertical. The protrusion is positioned on the block so that it will mate with any opening of an adjacently positioned course. In use, the blocks may be stacked to provide an interlocking structure wherein the protrusions of one block interfit or mate within the insets of another block.
Claims25
A masonry block comprising a front surface, a back surface, first and second sides, and a top surface and a bottom surface, said block comprising one or more protrusions positioned on said block top surface each of said protrusions comprising a side surface, said protrusion side surface circumscribing said protrusion, wherein said protrusion side surface has an angle of at least about 20.degree. from vertical, each of said protrusions positioned on said block top or bottom surface so as to mate with an opening of an adjacently positioned block and wherein each of said protrusion and said insets have relative sizes adapted to permit relative rotation of the protrusion and the inset within 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, said protrusion comprising a side surface, said side surface has an angle of at least about 20.degree. said protrusion side surface circumscribing said protrusion, from vertical, and said block also comprising first and second anchoring legs, said first leg extending from said block first side and said second leg extending from said block second side and wherein said protrusion and insets have relative sizes adapted to permit relative rotation of the protrusion and the inset within 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, said protrusion comprising a side surface, said protrusion side surface circumscribing said protrusion, said side surface having an angle of at least about 20.degree. from vertical, wherein said block protrusion is configured to mate with the inset of one or more adjacently positioned blocks and wherein said protrusion and insets have relative sizes adapted to permit relative rotation of the protrusion and the inset within which it is mated, whereby serpentine walls may be constructed from a plurality of such blocks.
