Abstract

Disclosed is an embedment tile for producing a tactilely detectable surface in a moldable material and method for using same. The tile comprises a tile member having a pattern of upwardly extending projections on its upper surface forming a tactilely detectable pattern, and a cross beam joined to the lower surface of the tile member. The cross beam defines a hollow chamber and apertures to allow for the release of air and inflow of moldable material to secure the embedment tile when the moldable material hardens. The cross beam can define a lower open portion at a cross beam end portion that eases installation by permitting a more direct flow path into the chamber for moldable material. The embedment tile can also include a reinforcing member joined to the lower surface of the tile member and/or a transverse reinforcing member joined to a lower surface of the tile member.

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 substantially enclosed chamber, a plurality of openings into the chamber, and a lower open portion at an end portion of the cross beam.

2. The embedment tile of claim 1, wherein the lower open portion is at least partially defined by an arcuate shape cut-out at the end of the cross beam.

3. The embedment tile of claim 1, wherein the lower open portion is defined by a pair of spaced apart and substantially vertical edges and arcuate edges.

4. The embedment tile of claim 1, and further comprising a reinforcing member disposed adjacent to the cross beam.

5. The embedment tile of claim 1, and further comprising a transverse reinforcing member joined to the lower surface of the tile member.

6. 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 substantially enclosed chamber and a plurality of openings into the chamber; and

a reinforcing member joined to the lower surface of the tile member.

7. The embedment tile of claim 6, wherein the reinforcing member is disposed adjacent to the cross beam.

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

9. The embedment tile of claim 6, wherein the reinforcing member is substantially channel-shaped.

10. The embedment tile of claim 6, wherein the cross beam defines a lower open portion at a cross beam end.

11. The embedment tile of claim 6, and further comprising:

a transverse reinforcing member joined to the lower surface of the tile member, and disposed at a substantially right angle to the cross beam.

12. 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 substantially enclosed chamber and a plurality of openings into the chamber; and

a transverse reinforcing member joined to the lower surface of the tile member.

13. The embedment tile of claim 12, wherein the transverse reinforcing member is substantially channel-shaped.

14. The embedment tile of claim 12, wherein the transverse reinforcing member is joined to the lower surface of the tile member adjacent to an edge of the tile member.

15. The embedment tile of claim 12, wherein the transverse reinforcing member is disposed between an end of the cross beam and an edge of the tile member.

16. The embedment tile of claim 12, wherein the cross beam defines a lower open portion at an end.

17. The embedment tile of claim 12, and further comprising:

a reinforcing member joined to the lower surface of the tile member at a substantially right angle to the transverse reinforcing member.
