Abstract:
1. A wall block comprising: a front portion including opposed top and bottom surfaces, opposed side surfaces and a front surface, at least one pin hole opening onto the opposed top and bottom surfaces and at least one pin receiving cavity opening onto at least one of the opposed top and bottom surfaces, the front surface having a length equal to the distance between the side surfaces and a height equal to the distance between the top and bottom surfaces; and two legs extending from the front portion in a direction opposite the front surface and having rear surfaces, the two legs having side walls that generally converge from the front surface toward the rear surfaces of the two legs of the block, the two legs being positioned such that when a wall is formed from multiple courses of the blocks which are offset from course to course by about one half the length of the front surface the legs in each course of blocks align vertically, the length of the front surface of the block being about twice the distance from the front surface of the block to the rear surfaces of the two legs, the legs being located asymmetrically on the block, and each leg having a curvilinear back portion.
