Abstract

A detectable warning tile system has a tile base with an upper surface and a lower surface. The upper surface has a plurality of upward projections therefrom. The tile base has two side edges for alignment with corresponding side edges of other tiles, and front and rear edges. An area of the upper surface of the tile base is formed free of the detectable warnings and may include a trough into or over which a replaceable tile section may be placed. The tile base and/or replaceable tile section may be configured to receive one or more individually-installable detectable warnings.

Claims

1. A detectable warning tile, comprising:

a generally planar tile base being formed as a single integral and continuous piece, the tile base having an upper surface and a lower surface, said upper surface having formed thereon a plurality of detectable warnings upwardly projecting therefrom, said tile having two side edges for alignment with corresponding side edges of other tiles, and front and rear edges;

wherein

all detectable warnings have substantially same base portion dimensions, and said upper surface includes a first area formed free of said detectable warnings, said first area having a width and length each greater than two times the largest base dimension of the detectable warnings, and

said first area contains at least one channel or frame structure that is adapted to receive at least one insertable piece that can be replaced in said at least one channel or frame structure, the channel or frame structure extending a distance less than the distance between the two side edges of the generally planar tile base, said at least one insertable piece being an insert of a same or different material from the material of the generally planar tile base;

wherein the detectable warnings are truncated domes.

2. The detectable warning tile according to claim 1, wherein said insertable piece has generally horizontal upper surfaces, said upper surfaces of said insertable piece having a texture formed thereon for increased friction.

3. The detectable warning tile according to claim 1, wherein the upper surface of said tile base adjacent to said insertable piece is provided with a texture for increased friction.

4. The detectable warning tile according to claim 1, wherein the insertable piece includes truncated domes having the base portion dimension of nominal 0.9 inch (23 mm) diameter, and a height of nominal 0.2 inch (5 mm).

5. The detectable warning tile according to claim 1, wherein flanges are formed on the lower surface of said tile base to provide strength and increased rigidity.

6. The detectable warning tile according to claim 1, further comprising at least one embedment anchor disposed at the lower surface of the tile base for embedment in a settable material.

7. The detectable warning tile according to claim 1 wherein the first area is formed to include at least one hole for receipt of an individually-installable insertable piece.

8. The detectable warning tile of claim 1, wherein the channel or frame structure of the first area includes a trough, the bottom surface of the insertable piece engaging the trough across a width of the insertable piece.

9. The detectable warning tile of claim 1, wherein the channel or frame structure is disposed closer to a first side edge of the generally planar tile base than the second side edge of the generally planar tile.

10. The detectable warning tile of claim 1, wherein the generally planar tile has side edges defined by top and bottom surfaces, the top and bottom surfaces are parallel to each other.

11. A detectable warning tile comprising:

a generally planar tile base being formed as a single integral and continuous piece, the tile base having an upper surface and a lower surface, said upper surface having thereon a plurality of detectable warnings upwardly projecting therefrom, said tile having two side edges for alignment with corresponding side edges of other tiles, and front and rear edges,

wherein a portion of said tile base is formed as a trough, the trough formed integrally with the upper surface of the detectable warning tile and defining a depression in the upper surface and being capable of receiving a replaceable tile section, and

wherein said depression is a channel or frame structure adapted to receive at least one insertable piece that has a same or different material than the tile base, said at least one insertable piece being removable from said tile base;

wherein detectable warnings are truncated domes, the detectable warnings having an attachment portion engaging a portion of the trough.

12. The detectable warning tile according to claim 11, wherein the trough is formed having a depth greater than a thickness of said replaceable tile section, the depth providing space beneath the replaceable tile section while said replaceable tile section is installed.

13. The detectable warning tile according to claim 11, wherein said trough has at least one open end for abutting or interconnecting with an open-ended trough of an adjoining tile.

14. The detectable warning tile according to claim 11, further comprising a gasket disposed at a lip of said trough for engagement with an edge area of said replaceable tile section.

15. The detectable warning tile of claim 11, wherein the detectable warnings include a feature to hinder turning thereof.
