Adjustable locator retaining wall block and mold apparatus
View Patent ↗A system of retaining wall blocks, a method of assembling a retaining wall block assembly, and a mold for manufacturing retaining wall blocks having adjustable engagement configurations.
1. A concrete retaining wall block comprising:
a front member having a height, a width, a front surface and a rear surface;
a rear member oriented substantially parallel to the front member;
two transverse members connecting the front member to the rear member and forming a core therebetween, the transverse members oriented substantially perpendicular to the front and rear members and spaced such that stacking multiple courses of the concrete retaining wall blocks in an overlap running bond causes the transverse members to substantially superpose each other, each transverse member comprising:
an integrally-formed engagement protrusion located on a bottom surface adjacent to the front member and adjacent to an integrally formed cavity, the sides of the integrally-formed engagement protrusion being substantially coplanar with the sides of the transverse member; and
a forward engagement cavity located on a top surface of the two transverse members adjacent to the front member, and a rear engagement cavity located on the top surface of the two transverse members adjacent to the rear member.
2. The concrete retaining wall block of claim 1 wherein a surface of the engagement cavity is parallel with a top surface of the front member.
3. The retaining wall block of claim 1 wherein the engagement protrusion is configured to interlock with the engagement cavity.
4. The retaining wall block of claim 1 wherein the engagement protrusion is configured to interlock with either the forward engagement cavity or the rear engagement cavity.
5. The retaining wall block of claim 1 wherein the front member further comprises a top portion and a bottom portion.
6. The retaining wall block of claim 1 wherein the front member further comprises a flat top portion and a flat bottom portion, the flat bottom portion configured to be placed on the flat top portion of an underlying one of the concrete retaining wall blocks.
7. The retaining wall block of claim 1 wherein the rear member further comprises a flat top portion and a flat bottom portion, the flat bottom portion configured to be placed on the flat top portion of an underlying one of the concrete retaining wall blocks.
8. The retaining wall block of claim 1 wherein the front member further comprises a flat top portion and a flat bottom portion, the flat bottom portion of the front member configured to be placed on the flat top portion of a front member of an underlying one of the concrete retaining wall blocks, and the rear member further comprises a flat top portion and a flat bottom portion, the flat bottom portion of the rear member configured to be placed on the flat top portion of a rear member of an underlying one of the concrete retaining wall blocks.
9. The retaining wall block of claim 1 wherein the rear member further comprises a height, a width, a front surface and a rear surface.
10. The retaining wall block of claim 1 wherein the rear member further comprises a height, a width less than the width of the front member, a front surface and a rear surface.
11. The retaining wall block of claim 1 wherein the rear member further comprises a rear surface that is substantially parallel to the front surface of the front member.
12. A concrete retaining wall block comprising:
a front member having a height, a width, a front surface and a rear surface;
a rear member oriented substantially parallel to the front member; and
two transverse members connecting the front member to the rear member and forming a core therebetween, each transverse member having a first cavity along a top surface adjacent the front member, a second cavity along the top surface adjacent the rear member and a third cavity along a bottom surface.
13. The concrete retaining wall block of claim 12 wherein the transverse members are oriented substantially perpendicular to the front and rear members.
14. The concrete retaining wall block of claim 12 wherein the transverse members are spaced such that stacking multiple courses of the concrete retaining wall blocks in an overlap running bond causes the transverse members to substantially superpose each other.
15. The concrete retaining wall block of claim 12 wherein each transverse member comprises an integrally-formed engagement protrusion located on a bottom surface adjacent to the front member.
16. The concrete retaining wall block of claim 15 wherein the sides of the integrally-formed engagement protrusion are substantially coplanar with the sides of the transverse member.
17. The concrete retaining wall block of claim 12 wherein each transverse member comprises an engagement cavity located on a top surface adjacent to the front member.
18. A concrete retaining wall block comprising:
a front member having a height, a width, a front surface, a rear surface, a flat top portion and a flat bottom portion, the flat bottom portion configured to be placed on the flat top portion of an underlying one of the concrete retaining wall blocks;
a rear member oriented substantially parallel to the front member and having a height, a width less than the width of the front member, a front surface, a flat top portion and a flat bottom portion, the flat bottom portion configured to be placed on the flat top portion of the underlying one of the concrete retaining wall blocks, and a rear surface that is substantially parallel to the front surface of the front member;
two transverse members connecting the front member to the rear member and forming a core therebetween, the transverse members oriented substantially perpendicular to the front and rear members and spaced such that stacking multiple courses of the concrete retaining wall blocks in an overlap running bond causes the transverse members to substantially superpose each other, each transverse member comprising:
an integrally-formed engagement protrusion located on a bottom surface adjacent to the front member, the sides of the integrally-formed engagement protrusion being substantially parallel with the sides of the transverse member; and
an engagement cavity located on a top surface adjacent to the front member, wherein a surface of the engagement cavity is parallel with a top surface of the front member, the engagement cavity further comprises a forward engagement cavity and a rear engagement cavity, the engagement protrusion is configured to interlock with the either the forward engagement cavity or the rear engagement cavity.
