Abstract

A retaining wall having a plurality of courses of retaining wall blocks including a first upper course and a second lower course. Each retaining wall block has opposed front and rear faces, opposed first and second side surfaces, and opposed and substantially parallel upper and lower surfaces, and at least one weight bearing pad extends from one of the upper and lower surfaces. The at least one weight bearing pad extends substantially from the rear face to the front face of the block. The weight bearing pads are the only areas of contact between the blocks in the first upper course and the blocks in the second lower course.

First claim

What is claimed is:

1. A block for forming a portion of an exposed surface of a wall of a structure, the block comprising:
a body with a front face opposed to a compound shaped rear face, the front face forming a portion of the exposed surface of the wall, opposed first and second side surfaces, and an upper surface opposed to a lower surface, the compound shape of the rear face of the body having two or more rearmost surfaces and two or more recessed surfaces, the block having two or more weight bearing surfaces extending a height from the upper surface of the body, each weight bearing surface having a planar surface, the planar surface of each weight bearing surface being the uppermost surface of the block;
wherein the body has a front portion extending from the front face to the two or more recessed surfaces of the compound shaped rear face and a rear portion extending from the two or more recessed surfaces to the two or more rearmost surfaces of the compound shaped rear face and wherein the two or more weight bearing surfaces extend along the upper surface of the body from the front portion to the rear portion of the body beyond each recessed surface of the compound shaped rear face.

2. The block of claim 1 , wherein the two or more rearmost surfaces includes more than two rearmost surfaces, wherein the two or more recessed surfaces includes more than two recessed surfaces, wherein the two or more weight bearing surfaces includes more than two weight bearing surfaces.

3. A wall block system for constructing a wall with one or more exposed surfaces comprising:
a plurality of wall blocks having a block body with a front face opposed to a compound shaped rear face, opposed first and second side surfaces, and an upper surface opposed to a lower surface, the compound shape of the rear face of the block body having two or more rearmost surfaces and two or more recessed surfaces, the plurality of wall blocks having two or more weight bearing surfaces extending a height from the upper surface of the block body, each weight bearing surface having a planar surface, the planar surface of each weight bearing surface being the uppermost surface of the wall block;
wherein the block body has a front portion extending from the front face to the two or more recessed surfaces of the compound shaped rear face and a rear portion extending from the two or more recessed surfaces to the two or more rearmost surfaces of the compound shaped rear face and wherein each one of the two or more weight bearing surfaces extends along the upper surface of the block body from the front portion to the rear portion of the block body beyond each recessed surface of the compound shaped rear face.

4. The wall block system of claim 3 , wherein the two or more rearmost surfaces includes more than two rearmost surfaces, wherein the two or more recessed surfaces includes more than two recessed surfaces, wherein the two or more weight bearing surfaces includes more than two weight bearing surfaces.

5. The wall block system of claim 3 , further comprising a plurality of connectors wherein one or more of the plurality of connectors couples one of the plurality of wall blocks to another one of the plurality of wall blocks.

6. The wall block system of claim 3 , wherein the wall constructed from the wall block system has at least a first exposed surface and a second exposed surface and wherein the front faces of some of the plurality of wall blocks form the first exposed surface and some of the plurality of wall blocks form the second exposed surface.

7. A wall having one or more exposed surfaces comprising a plurality of courses of wall blocks including at least a first upper course and an adjacent second lower course,
a plurality of wall blocks having a block body with a front face opposed to a compound shaped rear face, opposed first and second side surfaces, and an upper surface opposed to a lower surface, the compound shape of the rear face of the block body having two or more rearmost surfaces and two or more recessed surfaces, the plurality of wall blocks having two or more weight bearing surfaces extending a height from the upper surface of the block body, each weight bearing surface having a planar surface, the planar surface of each weight bearing surface being the uppermost surface of the wall block, the block body having a front portion extending from the front face to the two or more recessed surfaces of the compound shaped rear face and a rear portion extending from the two or more recessed surfaces to the two or more rearmost surfaces of the compound shaped rear face, wherein each one of the two or more weight bearing surfaces of the block body extends along the upper surface of the block body from the front portion to the rear portion of the block body beyond each recessed surface of the compound shaped rear face, and
wherein the front faces of the plurality of blocks of the at least first upper course and adjacent second lower course form the one or more exposed surfaces of the wall.

8. The wall of claim 7 , wherein the wall has at least a first exposed surface having at least a first upper course and an adjacent second lower course of wall blocks and a second exposed surface having at least a first upper course and an adjacent second lower course of wall blocks and wherein the front faces of some of the plurality of wall blocks form the first exposed surface of the wall and the front faces of some of the plurality of wall blocks form the second exposed surface of the wall.

9. The wall of claim 8 , wherein the first exposed surface of the wall has a vertical plane formed by the front faces of the wall blocks of the at least first upper course and adjacent second lower course and the second exposed surface of the wall has a vertical plane formed by the front faces of the wall blocks of the at least first upper course and adjacent second lower course, wherein the vertical plane of the first exposed surface is different than the vertical plane of the second exposed surface.

10. The wall of claim 7 , wherein two or more rearmost surfaces includes more than two rearmost surfaces, wherein the two or more recessed surfaces includes more than two recessed surfaces, wherein the two or more weight bearing surfaces includes more than two weight bearing surfaces.

11. The wall of claim 10 , wherein the wall has at least a first exposed surface having at least a first upper course and an adjacent second lower course of wall blocks and a second exposed surface having at least a first upper course and an adjacent second lower course of wall blocks and wherein the front faces of some of the plurality of wall blocks form the first exposed surface of the wall and the front faces of some of the plurality of wall blocks form the second exposed surface of the wall.

12. The wall of claim 11 , wherein the first exposed surface of the wall has a vertical plane formed by the front faces of the wall blocks of the at least first upper course and adjacent second lower course and the second exposed surface of the wall has a vertical plane formed by the front faces of the wall blocks of the at least first upper course and adjacent second lower course, wherein the vertical plane of the first exposed surface is different than the vertical plane of the second exposed surface.

13. The wall of claim 12 , further comprising a plurality of connectors wherein one or more of the plurality of connectors couples one of the plurality of wall blocks to another one of the plurality of wall blocks.

14. A block for forming a portion of an exposed surface of a wall of a structure, the block comprising:
a body comprising:
a plan
