Abstract:
A plurality of similar unitary monolithic blocks and interlock elements for use in vertically stacked horizontally extending rows in the construction of walls and the like; each block having a longitudinal and generally vertically extending front surface of a generally rectangular configuration viewed laterally, a pair of generally vertically extending generally rectangular and laterally rearwardly extending left and right hand end surfaces spaced longitudinally from each other and connected with opposite ends of said front surface, a longitudinally and generally vertically extending rear surface of generally rectangular configuration viewed laterally connected at opposite ends with said end surfaces, generally longitudinally and horizontally extending generally planar top and bottom surfaces of generally rectangular configuration disposed in parallel relationship with each other and connected at opposite ends with said end surfaces and at opposite sides with said front and rear surfaces, a vertically extending through opening in each block with upper and lower sections, each upper section being reduced in cross section relative to each lower section, and a plurality of small lateral interlock elements for securing the blocks in relatively fixed position laterally disposed respectively in said openings when the block units are stacked vertically in an assembled wall or the like, each interlock element having upper and lower portions with the lower portion reduced in cross section relative to the upper portion, and each lower opening section and upper interlock element portion being so shaped that blocks in vertically adjacent relationship reside in vertical alignment when an interlock element is positioned in a first attitude with its upper portion inserted in the lower section of the block opening of the upper block and with its lower portion entered in the upper section of the opening in the lower block, the shape of each opening section and the interlock element also accommodating a 180.degree. rotation of the interlock element about its vertical axis whereupon the shape of the element and through opening in the upper block cooperatively serve to relatively displace the blocks horizontally with the upper block positioned incrementally rearwardly in the provision of a battered wall.
