DETAILED DESCRIPTION OF THE INVENTION
In the description that follows, like parts are marked throughout the specification and drawings with the same reference numerals. The drawing figures might not be to scale and certain components can be shown in generalized or schematic form and identified by commercial designations in the interest of clarity and conciseness.
FIGS. 1A through 1C are diagrams of retaining wall cap 100 and blocks 200 and 300 in accordance with an exemplary embodiment of the present disclosure. As shown in FIG. 1A, cap block 100 is an modified arc segment having modified inner and outer radius surfaces, which are flattened to form a modified arc segment shape block having a length L1, outer width W, height H, an included angle α and an inner radius R, and can be used as a cap stone for placement on top of a retaining wall, such as where the retaining wall blocks are hollow and the cap stone is used to cover the hollow portion. As shown in FIG. 1B, first wall block 200 is an arc segment having modified inner and outer radius surfaces, which are flattened to form a modified arc segment shape block having a length L2, outer width 2W, height 3H, and included angle 2α and an inner radius R, and can be used to form the retaining wall. The hollow feature of first wall block 200 is not shown. As shown in FIG. 1C, second wall block 300 is an arc segment having modified inner and outer radius surfaces, which are flattened to form a modified arc segment shape block having a length L2, outer width 3W, height 2H, an included angle 3α and an inner radius R, and can be used to create variable and aesthetically-pleasing wall designs, as shown in FIGS. 4A through 4C. Length L1 can be greater than, equal to or less than length L2. In one embodiment of the present disclosure, length L1 is slightly larger than length L2, allowing cap block 100 to overhang first wall block 200 or second wall block 300. In this fashion, cap block 100 serves as a cap stone to a retaining wall comprised of first wall blocks 200, second wall blocks 300 and other suitable wall blocks. Essentially, the retaining wall blocks can be arranged as desired, such as shown, and the radial dimensions of the blocks allow the blocks to be configured so as to follow a contour, and to create a semi-random looking pattern. The various dimensions and number of blocks shown are exemplary, and other suitable dimensions and numbers of blocks can also or alternatively be used.
As shown in FIGS. 1A-1C, radius R refers to the distance between the inner radius of the sidewalls and a center point located at the intersection point of imaginary lines extending from the side walls of cap block 100, first wall block 200 or second wall block 300. However, radius R can extend to any suitable location along the sidewalls of cap block 100, first wall block 200 or second wall block 300, and can generally refer to a point that is common to cap block 100, first wall block 200 or second wall block 300, such as where those blocks overlap. In one exemplary embodiment of the present disclosure, cap block 100, first wall block 200, and second wall block 300 can all have included angles Nα (where N is typically an integer) and radii R such that the blocks are capable of modulating arrangements as described below.
FIGS. 2A through 2C are diagrams of a module of retaining wall blocks in accordance with an exemplary embodiment of the present disclosure. As shown in FIGS. 2A through 2C, two (2) cap blocks 100 can be positioned on a first wall block 200 to act as a cap stone. In addition, block 200 has a roughened texture on a front surface and rounded edges along the sides. In one exemplary embodiment, the roughened texture is created by splitting a larger block into two parts, and the rounded edges are formed by a rounded insert in the block mold. A splitting process can be used that creates the roughened and rounded edges at the top and bottom edges of the blocks.
FIGS. 3A through 3C are diagrams of a module of retaining wall blocks in accordance with an exemplary embodiment of the present disclosure. As shown in FIGS. 3A through 3C, three (3) cap blocks 100 can be positioned on a second wall block 300 to act as a cap stone. In addition, block 300 has a roughened texture on a front surface and rounded edges along the sides. In one exemplary embodiment, the roughened texture is created by splitting a larger block into two parts, and the rounded edges are formed by a rounded insert in the block mold. A splitting process can be used that creates the roughened and rounded edges at the top and bottom edges of the blocks.
FIGS. 4A through 4D are diagrams of a multi height retaining wall in accordance with an exemplary embodiment of the present disclosure. In another exemplary embodiment, a set of concrete blocks suitable for constructing a serpentine wall comprising a cap block 100, having height H, midpoint radius R and included angle α, first wall block 200, having height n*H, midpoint radius R and included angle m*α, and a second wall block 300, having height i*H, midpoint radius R and included angle j*α are provided. In another exemplary embodiment, cap block 100 can be a fractional element of wall blocks 200, 300.
As shown in FIGS. 4A through 4D, cap block 100, first wall block 200, and second wall block 300 can be arranged as desired to form an aesthetically pleasing, yet sturdy retaining wall assembly. For example, blocks 100, 200, 300 may be stacked and/or assembled end to end to form a straight or contoured retaining wall. The present disclosure enables blocks 100, 200, 300 to be arranged side-to-side with abutting front faces or side-to-side with abutting front and back faces (i.e. an inversed side-by-side arrangement), so as to allow the retaining wall to define or follow landscape contours. The cap blocks 100 cover the hollow portions of first wall block 200 and second wall block 300, to serve aesthetic purposes and to prevent an unsightly wall configuration. In one embodiment of the present disclosure, the hollow cavities of the retaining wall blocks 200 and 300 can be filled with dirt, gravel, stone, concrete, rebar, or any other conventional material suitable to provide for a sturdy retaining wall assembly.
It should be emphasized that the above-described embodiments are merely examples of possible implementations. Many variations and modifications may be made to the above-described embodiments without departing from the principles of the present disclosure. All such modifications and variations are intended to be included herein within the scope of this disclosure and protected by the following claims.
