Abstract

A seal assembly is configured to seal a tile gap between a pair of tiles. Each of the tiles may include a tile side surface. At least one of the tiles may include a groove which may be formed along a length of the tile side surface. The seal assembly may comprise a gasket assembly including first and second bulb portions which may be interconnected by a web. A spacer rope may be positionable along the web. The gasket assembly may define a folded configuration for mounting within the tile gap when the web is wrapped around the spacer rope such that the second bulb portion is positioned between the spacer rope and the first bulb portion. The second bulb portion may be receivable within the groove.

5. The seal assembly of claim 1 wherein:

the tile gap is at least partially bounded by a substructure having a substructure surface;

the gasket assembly being positionable within the tile gap in spaced relation to the substructure surface such that an inner gap is formed between the gasket assembly and the substructure surface.

6. The seal assembly of claim 1 wherein:

at least one of the first and second bulb portions is comprised of a bulb core at least partially encircled by a bulb jacket.

7. The seal assembly of claim 6 wherein:

the bulb core, bulb jacket and web have a ceramic composition.

8. The seal assembly of claim 1 wherein:

the spacer rope has a silica composition.

9. A seal assembly for sealing a tile gap defined by opposing tile side surfaces of a corresponding pair of tiles, at least one of the tile side surfaces having a groove formed along a length thereof, the seal assembly comprising:

a gasket assembly, including;

first and second bulb portions interconnected by a web; and

a spacer rope interposed between the first and second bulb portions when the gasket assembly is in an open configuration;

wherein;

the gasket assembly defines a folded configuration when the web is at least partially wrapped around the spacer rope;

the web being resiliently resistant to wrapping around the spacer rope when the gasket assembly is in the folded configuration such that the gasket assembly and the spacer rope form a spring mechanism;

the second bulb portion being at least partially receivable within the groove;

the spacer rope and the first bulb portion being located outside of the groove when the seal assembly is mounted in the tile gap in sealing engagement with the tile side surfaces.

10. The seal assembly of claim 9 wherein:

the gasket assembly is movable from the open configuration to the folded configuration for mounting in the tile gap.

11. A seal assembly for sealing a tile gap defined by opposing tile side surfaces of a corresponding pair of tiles, at least one of the tile side surfaces having a tile exterior surface and a groove formed along a length thereof, the seal assembly comprising:

a gasket assembly, including;

first and second bulb portions interconnected by a web; and

a spacer rope interposed between the first and second bulb portions when the gasket assembly is in an open configuration;

wherein;

the gasket assembly defines a folded configuration when the web is at least partially wrapped around the spacer rope;

the web being resiliently resistant to wrapping around the spacer rope when the gasket assembly is in the folded configuration such that the gasket assembly and the spacer rope form a spring mechanism;

the gasket assembly being oriented in the tile gap such that the first bulb portion is positioned proximate the tile exterior surface.

12. A sealing system for sealing a tile gap defined by opposing tile side surfaces of a pair of tiles, comprising:

a groove formed along a length of at least one of the tile side surfaces;

a seal assembly including;

a gasket assembly having first and second bulb portions interconnected by a web; and

a spacer rope positionable along the web;

wherein;

the gasket assembly defines a folded configuration for mounting within the tile gap when the web at least partially encircles the spacer rope such that the second bulb portion is positioned between the spacer rope and the first bulb portion;

the second bulb portion being at least partially receivable within the groove.

13. The sealing system of claim 12 wherein:

the web is resiliently resistant to wrapping around the spacer rope when the gasket assembly is in the folded configuration such that the gasket assembly and the spacer rope form a spring mechanism, the spring mechanism biasing the second bulb portion into the groove when the seal assembly is mounted in the tile gap.

14. The sealing system of claim 12 wherein:

at least one of the tiles has a tile exterior surface;

the gasket assembly being oriented in the tile gap such that the first bulb portion is positioned proximate the tile exterior surface.

15. The sealing system of claim 14 wherein:

the groove is oriented in substantially parallel relation to the tile exterior surface.

16. A vehicle, comprising:

at least two tiles defining a tile gap therebetween, at least one of the tiles having a tile side surface with a groove formed therein; and

a seal assembly, including;

a gasket assembly having first and second bulb portions interconnected by a web; and

a spacer rope having the web wrapped partially therearound such that the second bulb portion is positioned between the first bulb portion and the spacer rope when the gasket assembly is in a folded configuration;

wherein;

the second bulb portion is receivable within the groove when the seal assembly is mounted within the tile gap.

17. The vehicle of claim 16 wherein:

the gasket assembly defines an open configuration when the spacer rope is positioned between the first and second bulb portions;

the gasket assembly being movable from the open configuration to the folded configuration for mounting in the tile gap.

18. The vehicle of claim 16 wherein:

21. The method of claim 20 further comprising the step of:

biasing the second bulb portion into the groove.

22. The method of claim 20 further comprising the step of:

orienting the seal assembly within the tile gap such that the first bulb portion is positioned proximate the tile exterior surface.

23. The method of claim 20 wherein the tile gap is at least partially bounded by a substructure having a substructure surface, the method further comprising the step of:

forming a groove in at least one of the tile side surfaces;

providing a seal assembly comprising a web interconnecting first and second bulb portions and having a spacer rope interposed therebetween when the gasket assembly is in an open configuration;

positioning the gasket assembly into a folded configuration by wrapping the web at least partially around the spacer rope such that the first bulb portion is positioned on a side of the second bulb portion opposite the spacer rope; and
