Abstract

Tactile detection embedment plates used in pedestrian walkways releasably aligned by a bracket on at least one of the embedment plates. The bracket can be mated with a bracket on another plate engage a wedge or wedge parts for a releasable plate assembly connection.

Claims

1. A tactile embedment plate assembly comprising:

a first plate;

a first bracket joined to the first plate;

a second plate arranged co-planar and adjacent to the first plate;

a second bracket joined to the second plate and aligned with the first bracket to define a receiver yoke there between; and

a wedge joined to the first bracket and disposed in the receiver yoke.

2. The tactile embedment plate assembly of claim 1, wherein:

the second bracket includes a second wedge surface spaced apart from the second plate and the first wedge surface to at least partially define the receiver yoke.

3. The tactile embedment plate assembly of claim 1, and further comprising:

a second wedge joined to the second bracket and disposed in the receiver yoke.

4. The tactile embedment plate assembly of claim 1, and further comprising:

a second wedge joined to the second bracket and disposed in the receiver yoke and bearing against the wedge.

5. The plate assembly of claim 1, wherein the first bracket is disposed adjacent to the second bracket.

6. The plate assembly of claim 1, wherein the first bracket is spaced apart from the second bracket.

7. The tactile embedment plate assembly of claim 1, wherein:

the first bracket includes a first foot; and

the second bracket includes a second foot.

8. The tactile embedment plate assembly of claim 1, wherein the wedge is substantially trapezoidal in shape.

9. The tactile embedment plate assembly of claim 1, wherein the wedge is a rod with a substantially round cross-sectional shape.

10. The tactile embedment plate assembly of claim 1, and further comprising:

a clip releasably joined to the first bracket and the second bracket.

11. A tactile embedment plate assembly comprising:

a first plate;

a first bracket joined to the first plate and the first bracket includes a shoulder;

a second plate adjacent to and co-planar with the first plate and bearing at least partially on the first bracket shoulder;

a second bracket joined to the second plate, and the second bracket includes a shoulder and the first plate bears at least partially on the second bracket shoulder;

wherein

a receiver yoke is defined by the first bracket and the second bracket;

a first wedge part joined to the first bracket and disposed in the receiver yoke; and

a second wedge part joined to the second bracket and engaging the first wedge part.

12. The tactile embedment plate assembly of claim 11, and further comprising:

A wedge retainer clip releasably joined to the wedge and the first bracket.

13. The tactile embedment plate assembly of claim 11, wherein the first bracket and second bracket are spaced apart.

14. The tactile embedment plate assembly of claim 11, wherein the first bracket and second bracket are adjacent to one another.

15. The tactile embedment plate assembly of claim 11, wherein the receiver yoke is wedge-shaped, and a second wedge is disposed in the receiver yoke.

16. The tactile embedment plate assembly of claim 11, wherein:

the receiver yoke is defined by a first wedge surface on the first bracket, and the first surface is spaced apart from the first plate, and

a second surface on the second bracket, and the second surface is spaced apart from the second plate; and

the first wedge part is wedged against the second surface.

17. The tactile embedment plate assembly of claim 11, wherein:

the first wedge part is formed integrally with the first bracket.

18. The tactile embedment plate assembly of claim 11, wherein the second wedge part is formed integrally with the second bracket.

19. The tactile embedment plate assembly of claim 11, wherein:

the first bracket shoulder includes a lip for engaging a notch in a lower surface second plate.

20. The tactile embedment plate assembly of claim 11, and further comprising:

a lip on the second bracket for engaging a notch on the first embedment plate.

21. An alignment bracket for aligning a first tactile embedment plate to a second tactile embedment plate in a substantially co-planar relationship, the alignment bracket comprising:

a first bracket joined to the first tactile embedment plate;

a second bracket joined to the second tactile embedment plate and aligned with the first bracket; and

a clip releasably joined to the first bracket and the second bracket.

22. The alignment bracket of claim 21, wherein the first bracket comprises:

a shoulder on which the second tactile embedment plate bears.

23. The alignment bracket of claim 21, wherein the first bracket comprises:

a shoulder on which the second tactile embedment plate bears; and

a foot extending from the first bracket, substantially parallel to the first tactile embedment plate.

24. The alignment bracket of claim 21, wherein the first bracket comprises:

a shoulder on which the second tactile embedment plate bears; and

a wedge surface that at least partially defines the receiver yoke.

25. The alignment bracket of claim 21, wherein:

the first bracket comprises;

a shoulder on which the second tactile embedment plate bears, and a wedge surface that at least partially defines the receiver yoke; and

the second bracket comprises;

a shoulder on which the first tactile embedment plate bears and a wedge surface that at least partially defines the receiver yoke; and

a wedge surface that at least partially defines the receiver yoke.

26. A method of installing plate assemblies for being cast in concrete or asphalt pavement which includes the steps of:

setting a first plate with a first edge in a desired position;

setting a second plate with a second edge adjacent to the first edge of the first plate so that the second plate is substantially co-planar position with the first plate and to insert a bracket extending from the second plate under the first plate to bring the bracket into bearing support of the first plate by aligning the bracket on the second plate with a bracket on the first plate to define a receiving yoke; and

sliding the first plate first edge relative to the second plate second edge to insert a wedge joined to the second bracket into the receiving yoke.

27. The method of claim 26, and further comprising the step of:

sliding an edge of the second plate along an edge of the first plate to adjust a spacing between the bracket on the first plate and a bracket on the second plate.

28. The method of claim 26, and further comprising-the step of:

engaging a lip on the bracket of the second plate with a notch on the first plate to releasably join the second plate and the first plate.

29. The method of claim 26, and further comprising the step of:

attaching a retainer clip to the first bracket and the second bracket.

30. The method of claim 26, and further including the step of:

placing a moldable material around and under the first plate and the second plate to form pavement having a detectable warning surface.

31. The method of claim 26, and further comprising the steps of:

engaging a lip on the bracket of the second plate with a notch in the first plate to create a plate assembly of the second plate and the first plate; and

installing the plate assembly into a pavement location to at least partially define a detectable warning surface.
