Abstract

A floor tile for use in a flooring system comprises an upper surface operable for use as a portion of a flooring installation and a support lattice operable to support the upper surface. The support lattice includes a plurality of support members extending downwardly from an underside of the upper surface and terminating in lower sections collectively defining a subfloor contact profile and a plurality of interconnecting members laterally interconnecting two or more of the support members. At least some of the plurality of support members extend downwardly at an oblique angle to the upper surface.

Claims

1. A resilient floor tile for use in a flooring system, comprising:

an upper surface; and

a support lattice operable to resiliently support the upper surface, the support lattice including;

a plurality of support members extending downwardly from an underside of the upper surface and terminating in lower sections; and

a plurality of interconnecting members laterally interconnecting the lower sections of at least two support members and collectively defining a subfloor contact profile,

wherein at least two of the interconnecting members define alternating arcuate concave and convex support members.

2. The floor tile of claim 1, wherein the upper surface comprises a substantially continuous plane.

3. The floor tile of claim 1, wherein the upper surface, the support members and the interconnecting members are formed as an integral piece.

4. The floor tile of claim 1, wherein the support members and the interconnecting members extend longitudinally substantially along an entire length of the underside of the upper surface of the floor tile.

5. The floor tile of claim 1, further comprising at least one section of engagement material carried by the subfloor contact profile, the engagement material being formed of a material relatively more pliable than the subfloor contact profile.

6. The floor tile of claim 1, further comprising:

a protruding connecting member associated with a lateral edge of the floor tile; and

a gutter connecting member associated with an opposite lateral edge of the floor tile;

the protruding connecting member and the gutter connecting member being operable to provide substantially liquid-tight lateral edge connection of adjacent floor tiles.

7. The floor tile of claim 6, further comprising at least one separable mating connector sized and shaped to be received within end edge portions of the floor tile, the mating connector being operable to provide substantially liquid-tight end edge connection between adjacent floor tiles.

8. A resilient floor tile for use in a flooring system, comprising:

an upper surface;

a support lattice configured to resiliently support the upper surface, the support lattice including;

a plurality of rails extending longitudinally and downwardly from an underside of the upper surface and terminating in lower sections;

a plurality of interconnecting members laterally interconnecting the lower sections of at least two rails to collectively define a subfloor contact profile wherein at least two of the interconnecting members define alternating arcuate concave and convex support members; and

at least one section of engagement material carried by a lowermost section of the plurality of interconnecting members, the engagement material being formed of a material relatively more pliable than the subfloor contact profile.

9. The floor tile of claim 8, wherein the upper surface comprises a substantially continuous plane.

10. The floor tile of claim 8, further comprising a plurality of deformable elongate openings defined by the underside of the upper surface, the rails and the interconnecting members, and wherein the elongate openings allow the rails and interconnecting members to flex in response to a load applied to the upper surface.

11. The floor tile of claim 10, further comprising at least one separable mating connector sized and shaped to be received within the elongate openings accessible from the end edges of the floor tile, the separable mating connector being operable to provide substantially liquid-tight end edge connection of adjacent floor tiles.

12. The floor tile of claim 8, wherein the upper surface, the plurality of rails and the interconnecting members are formed as an integral piece.

13. The floor tile of claim 8, wherein the rails and the interconnecting members extend longitudinally substantially along an entire length of the underside of the upper surface of the floor tile.

14. The floor tile of claim 8, wherein at least some of the rails include an arcuate shape.

15. The floor tile of claim 8, wherein at least some of the plurality of rails extend from the underside of the upper surface at an oblique angle to the upper surface.

16. The floor tile of claim 8, further comprising:

a protruding connecting member associated with a lateral edge of the floor tile; and

a gutter connecting member associated with an opposing lateral edge of the floor tile;

the protruding connecting member and the gutter connecting member being operable to provide substantially liquid-tight lateral edge connection of adjacent floor tiles.

17. A resilient floor tile for use in a flooring system, comprising:

an upper surface; and

a support lattice resiliently supporting the upper surface, the support lattice including;

a plurality of rails extending longitudinally along an underside of the upper surface and defining a plurality of open spaces therebetween, the plurality of rails extending downwardly from the underside of the upper surface and terminating in lower sections; and

a plurality of interconnecting members laterally interconnecting the lower sections of two or more of the rails and at least partially enclosing the open spaces defined therebetween to form a plurality of elongate openings having a deformable quadrilateral geometry, and to collectively define a subfloor contact profile,

wherein the elongate deformable openings allow at least some of the plurality of rails and interconnecting members to flex in response to a load applied to the upper surface;

wherein at least two of the interconnecting members define alternating arcuate concave and convex support members.

18. The floor tile of claim 17, wherein the deformable quadrilateral geometry further comprises at least two angled rails disposed between two vertical rails, wherein the angled rails extend downwardly from the underside of the upper surface at an oblique angle greater than or about 30 degrees from perpendicular to the underside of the upper surface.

19. The floor tile of claim 17, wherein the upper surface, the plurality of rails and the interconnecting members are formed as an integral piece.

20. The floor tile of claim 17, wherein the rails and the interconnecting members extend longitudinally substantially along an entire length of the underside of the upper surface of the floor tile.

21. The floor tile of claim 17, further comprising at least one section of engagement material carried by the subfloor contact profile, the engagement material being formed of a material relatively more pliable than the subfloor contact profile.

22. The floor tile of claim 17, further comprising:

a protruding connecting member associated with a lateral edge of the floor tile; and

a gutter connecting member associated with an opposing lateral edge of the floor tile;

the protruding connecting member and the gutter connecting member being operable to provide substantially liquid-tight lateral edge connection of adjacent floor tiles.
