Abstract

An embedment tile for producing a tactilely detectable surface in a pedestrian walkway with an improved cross beam anchor.

Claims

1. An embedment tile for producing a tactilely detectable surface in a moldable material, comprising:

a tile member having an upper surface and a lower surface, the upper surface having a plurality of projections extending upward therefrom;

a cross beam joined to the lower surface of the tile member, the cross beam defining a reinforcing rib, and a plurality of moldable material openings.

2. The embedment tile of claim 1, wherein the reinforcing rib extends laterally from the cross beam.

3. The embedment tile of claim 1, wherein the reinforcing rib extends substantially longitudinally along the crossbeam.

4. The embedment tile of claim 1, wherein the crosses beam includes a side wall and a moldable material anchor portion joined at a lower edge of the side wall.

5. The embedment tile of claim 1, wherein the moldable material openings extend through at least a portion of the reinforcing rib.

6. The embedment tile of claim 1, wherein the crosses beam includes a substantially channel-shaped portion joined to the tile member.

7. The embedment tile of claim 6, wherein the channel-shaped proton defines holes through which connectors extend and releasably secure the tile member to the cross beam.

8. The embedment tile of claim 6, wherein the reinforcing rib is formed integrally with the cross beam.

9. The embedment tile of claim 6, wherein the reinforcing rib is substantially v-shaped in cross section.

10. An embedment tile for producing a tactilely detectable surface in a moldable material, comprising:

a tile member having four corners, an upper surface, and a lower surface, and the upper surface having a plurality of projections extending upward therefrom; and

a plurality of cross beams joined to the lower surface of the tile member, wherein at least two of the cross beams extend between opposite corners of the tile member and are arranged in an intersecting pattern, and at least one cross beam defines a reinforcing rib, and a plurality of moldable material openings.

11. The embedment tile of claim 10, and further comprising:

a junction box joined to a central portion of the lower surface of the tile member and joined to at least two of the cross beams.

12. The embedment tile of claim 11, wherein the junction box includes connection surfaces in shapes that mate with shapes of the cross beams.

13. The embedment tile of claim 10, wherein the reinforcing rib extends substantially longitudinally along the crossbeam.

14. The embedment tile of claim 10, wherein at least one cross beam includes a side wall and a moldable material anchor portion joined at a lower edge of the side wall.

15. The embedment tile of claim 10, wherein the moldable material openings extend through at least a portion of the reinforcing rib.

16. The embedment tile of claim 10, wherein the cross beam includes a substantially channel-shaped portion joined to the tile member.
