Abstract

The disclosure provides, among other things, a paver that includes a body having a top surface, a bottom surface opposite the top surface, and a peripheral side. The peripheral side is defined about a perimeter of the paver and joins the bottom and top surfaces. The peripheral side defines a peripheral edge displaced from the top surface and the bottom surface that traverses the perimeter of the body along the peripheral side. The edge is adapted to engage a complementary edge on a peripheral side of an adjacent paver, such that the pavers interlock when a vertical force is applied to the paver. In another aspect, a masonry wall unit is provided for building walls similar in concept to the paver.

Claims (20)

1. A construction block unit having a first surface, a second surface opposite the first surface, and a plurality of sides separating the first and second surfaces that cooperate with the first and second surfaces to define a volume of the block, wherein at least one of the plurality of sides of the block is defined at least in part by first and second twisted facets that converge toward an intermediate plane located between the first and second surfaces of the block, the intermediate plane having a shape that is substantially the same as portions of the first and second surfaces that project on the intermediate plane, the intermediate plane being rotated with respect to the first and second surfaces by an angle in excess of zero degrees, each of the first and second facets having a surface that twists along the side of the block, the twisting surfaces of the first and second twisted facets cooperating to define a surface that transitions from a concave surface to a convex surface along the side of the block.

2. The construction block unit of claim 1 , wherein each side of the block has at least one pair of twisted facets and the intermediate plane defines a peripheral edge that is continuous around a perimeter of the block.

3. The construction block unit of claim 1 , wherein each side of the block has at least one pair of twisted facets and wherein the block has at least one chamfered corner, and further where the intermediate plane defines a peripheral edge that is continuous around a perimeter of the block except for interruptions at the at least one chamfered corner.

4. The construction block unit of claim 1 , wherein the predetermined angle is between about five degrees and about fifteen degrees.

5. The construction block unit of claim 1 , wherein the first and second surfaces of the block are square in shape.

6. The construction block unit of claim 1 , wherein the construction block includes a plurality of adjacent rotated intermediate planes laying in the same plane.

7. The construction block unit of claim 1 , wherein the first and second surfaces of the block are triangular in shape.

8. The construction block unit of claim 1 , wherein the first and second surfaces of the block are hexagonal in shape.

9. The construction block unit of claim 1 , wherein the first and second surfaces of the block are rectangular in shape.

10. The construction block unit of claim 6 , wherein the first and second surfaces of the block are rectangular in shape.

11. The construction block unit of claim 6 , wherein the first and second surfaces of the block are square in shape.

12. The construction block unit of claim 1 , wherein at least one of the first and second twisted facets has a smooth, continuous surface.

13. The construction block unit of claim 1 , wherein the block includes a reveal along at least one of the first and second surfaces.

14. The construction block unit of claim 1 , wherein the intermediate plane is parallel to at least one of the first and second surfaces.

15. The construction block unit of claim 1 , wherein the block includes two parallel intermediate planes laterally spaced from each other and at least four twisted facets on each side of the block.

16. The construction block unit of claim 1 , wherein the block includes three parallel intermediate planes laterally spaced from each other and at least six twisted facets on each side of the block.

17. The construction block unit of claim 1 , wherein the first and second twisted facets define an inflection point proximate the middle of the intermediate plane dividing the first and second twisted facets, wherein the facets are neither concave nor convex at the inflection point.

18. The construction block unit of claim 1 , wherein the intermediate plane has the same dimensions as the portions of the first and second surfaces that project on the intermediate plane.

19. The construction block unit of claim 1 , wherein less than all of the sides in the plurality of sides include a twisted facet.

20. A wall or a ground covering made from wall blocks or pavers according to claim 1 .
