Abstract

Connectors for joining adjacent modular floor covering units. The connectors include a film and an adhesive layer coated on one side of the film. To install tiles using the connectors, a first tile is placed on the floor and a connector is positioned so that the adhesive layer faces upward and does not contact the floor. The connector is typically positioned so that only a portion of the adhesive layer adheres to the underside of the tile, leaving the remainder of the connector extending from the underside of the tile. Tiles are then positioned adjacent the first tile so that a portion of the connector adheres to the adjacent tiles. In this way, the connectors span adjacent tile edges. The tiles are assembled on a underlying flooring surface without the need to attach them to the floor surface. Rather, the tiles are linked to each other with the connectors, so that the tiles create a floor covering that “floats” on the underlying floor surface.

Claims (32)

1. A stack of connectors for installing modular tiles, each having an underside, on a floor surface without attaching the tiles to the floor surface, the stack comprising:

at least a first connector and a second connector each comprising a film with an adhesive side having a layer of adhesive and an opposite side, wherein the layer of adhesive is capable of forming a bond with the undersides of the tiles so that, when a connector spans adjacent edges of adjacent tiles so that the layer of adhesive contacts the underside of each of the adjacent tiles, the layer of adhesive prevents relative movement between the adjacent tiles while extending along only a portion of the adjacent edges; and

wherein the first connector and second connector are releasably attached to one another.

2. The stack of connectors of claim 1 , wherein the stack is in a dispenser.

3. The stack of connectors of claim 1 , wherein the first connector and the second connector are adjacent to one another and oriented in a similar direction, wherein the adhesive layer of the first connector attaches to the opposite side of the second connector.

4. The stack of connectors of claim 3 , wherein the opposite side of the second connector comprises a release coating.

5. The stack of connectors of claim 1 , wherein the first connector and the second connector are adjacent to one another and oriented in a similar direction, wherein the adhesive layer of the first connector attaches to a release material and the opposite side of the second connector attaches to the release material.

6. A connector for connecting modular tiles, each having an underside, on a floor surface, without attaching the tiles to the floor surface, comprising:

a film;

a layer of adhesive located on a side of the film, wherein the layer of adhesive comprises a water-based adhesive and is capable of forming a bond with the undersides of the tiles so that, when a connector spans adjacent edges of adjacent tiles so that the layer of adhesive contacts the underside of each of the adjacent tiles, the layer of adhesive prevents relative movement between the adjacent tiles while extending along only a portion of the adjacent edges.

7. The connector of claim 6 , wherein the adhesive has low volatile organic content.

8. The connector of claim 6 , wherein the adhesive has no volatile organic content.

9. The connector of claim 6 , wherein the adhesive is plasticizer resistant.

10. A connector for connecting modular tiles, each having an underside, on a floor surface, without attaching the tiles to the floor surface, comprising:

a film;

a layer of adhesive located on a side of the film, wherein the layer of adhesive comprises an acrylic-based adhesive and is capable of forming a bond with the undersides of the tiles so that, when a connector spans adjacent edges of adjacent tiles so that the layer of adhesive contacts the underside of each of the adjacent tiles, the layer of adhesive prevents relative movement between the adjacent tiles while extending along only a portion of the adjacent edges.

11. The connector of claim 10 , wherein the adhesive has low volatile organic content.

12. The connector of claim 10 , wherein the adhesive has no volatile organic content.

13. The connector of claim 10 , wherein the adhesive is plasticizer resistant.

14. The connector of claim 10 , wherein the adhesive is primarily an acrylate terpolymer.

15. The connector of claim 10 , wherein the adhesive is a tackified acrylate copolymer.

16. A connector for installing modular tiles, each having an underside, on a floor surface without attaching the tiles to the floor surface, comprising:

a. a film;

b. a layer of adhesive located on a side of the film, wherein the layer of adhesive is capable of forming a bond with the undersides of the tiles so that, when a connector spans adjacent edges of adjacent tiles so that the layer of adhesive contacts the underside of each of the adjacent tiles, the layer of adhesive prevents relative movement between the adjacent tiles while extending along only a portion of the adjacent edges; and

c. alignment indicia for facilitating installation of the tiles.

17. The connector of claim 16 , wherein the indicia is a crosshair.

18. The connector of claim 16 , wherein the indicia is a line.

19. The connector of claim 16 , wherein the indicia is a dot.

20. The connector of claim 16 , wherein the indicia is a block.

21. The connector of claim 16 , wherein the indicia comprises two colors.

22. The connector of claim 16 , wherein the indicia divides the connector into quadrants.

23. The connector of claim 22 , wherein the quadrants comprise two colors.
