Patent ID: 7037047

Claim:
A concrete corner block for use in constructing an exterior corner of a retaining wall, the concrete corner block comprising: a front surface, a rear surface, first and second end surfaces extending from the front surface to the rear surface and intersecting the front and rear surfaces at generally right angles, a generally planar top surface, and a generally planar bottom surface; the first and second end surfaces having generally equal lengths, the front surface and the rear surface having generally equal lengths, the length of the end surfaces being less than the length of the front surface and the rear surface, and the front surface and at least one of the end surfaces having textures wherein the degree of texturing of the front surface and the one end surface is greater than the degree of texturing of the top surface; first and second core openings extending through the block from the top surface to the bottom surface, the first core opening being positioned between the first end surface and the second core opening and the second core opening being positioned between the second end surface and the first core opening; and each core opening being defined by a side face which converges from the top surface of the block to the bottom surface of the block so that the area of the core opening at the top surface is greater than the area of the core opening at the bottom surface; and for each core opening, a first portion of the side face closest to the front surface and a second portion of the side face closest to the adjacent end surface of the block converges to a greater degree than other portions of the side face.
