This invention pertains to a tiled wall assembly suitable for use in areas where fluids can splash on the tiles. Such areas include showers, bathrooms, closets, coves, surgical rooms, kitchens and other wet rooms.
Traditionally, grout has been used to fill in the spaces between adjacent wall tiles. However, the grout frequently becomes discolored requiring cleaning and/or sections of grout break away and require replacement. There is an ongoing need therefore to provide tiled wall assemblies that do not require grout.
PCT publication WO 2016/142647 A1 to Horton et al describes a wall panel suitable for bathrooms, wet rooms and the like. The panel is water impervious and comprises a core of wood plastics composite (WPC) and a laminate adhesively attached to the core. In preferred embodiments, the core is a wood plastics composite foamed board. The wood plastics composite preferably comprises PVC and wood fiber. The wall panel may be provided with a tongue-and-groove interlocking system with tongue and groove edges. The system is configured to provide a contact area across less than the thickness of the panel which achieves a tight join at the front face and eliminates a visible gap. It also increases tolerance for machining errors or variation. The tongue-and-groove interlocking system is designed to provide tolerance for walls which are not precisely planar but may be bowed or uneven to a certain extent.
United States Publication 2006/0080910 to Silvano discloses a tile system that does not require a grout or other material to be spread over the tiles during the installation process. Accordingly, the tile system includes tiles that carry a flange that attaches to adjacent tiles upon installation. The flange serves the function of the grout and eliminates the need for a separate grout compound. A tile in accordance with the invention includes a primary tile component and a flange for attaching for other tiles.

While the present invention is capable of being embodied in various forms, the description below of several embodiments is made with the understanding that the present disclosure is to be considered as an exemplification of the invention, and is not intended to limit the invention to the specific embodiments illustrated. Headings are provided for convenience only and are not to be construed to limit the invention in any manner. Embodiments illustrated under any heading or in any portion of the disclosure may be combined with embodiments illustrated under the same or any other heading or other portion of the disclosure.
Any combination of the elements described herein in all possible variations thereof is encompassed by the invention unless otherwise indicated herein or otherwise clearly contradicted by context. For example, if a wall assembly described in an embodiment may vary according to an additional feature or claim element, it is to be understood that other wall assemblies described in other embodiments may also vary according to that same additional feature or claim element unless otherwise indicated herein or otherwise clearly contradicted by context.
As used herein, the term “chamfer” refers to a cut on the edge or corner of something, such as a tile, that makes it slope slightly rather than being perfectly square.
As used herein, the term “dado” refers to a rectangular groove cut into a tile edge so that a like piece may be fitted into it.
As used herein, the term “extends the full length of the wall” means that the longest dimension of the tile runs from wall to wall and therefore runs the full length of one dimension of the wall it covers.
By “non-porous tile” is meant that fluid remains on the surface of the tile or runs off the tile with no penetration of fluid into the tile (such as, for example, less than 0.5 percent by weight absorption of fluid into the tile; or less than 0.1 percent by weight absorption; or less than 0.01 percent by weight absorption).
Wall Assembly
In a preferred embodiment, each first and second sidewall tile and each rear wall tile extends the full length of one dimension of the first and second sidewalls and the rear wall, respectively. For example, If the tile dimensions are given by the tile length×tile width×tile thickness (with tile length>tile width), and the wall area to be covered (for example, a sidewall, or the rear wall), has wall dimensions given by the wall length×wall width (with wall length>wall width), then the length dimension of the tile extends the full length of one of the wall dimensions (the Figures show the tile length dimension extends the full length of the wall width dimension, although the tile length dimension could alternatively extend the full length of the wall length dimension—that is, the tile length could run horizontally as shown in the Figures, or it could run vertically).
The wall assembly is free of grout between adjacent tiles.
In a preferred embodiment, each first and second sidewall tile and each front wall tile extends the full length of one dimension of the first and second sidewalls and the front wall except where there is an opening 16 in the front wall. In this instance the front tiles, e.g. 15a-15d terminate at the front wall opening. In
The wall assembly is free of grout between adjacent tiles.
Sidewall Tile
Rear Tile
In a similar manner as described for the sidewall tiles, the rear wall tiles are chamfered on both the top and bottom edges. The chamfer may extend over the full length of the tile or terminate short of the tile ends.
Front Wall Tile
In parts of the front wall where there is no opening 16, the front wall tile is as described for the rear wall tile of
In a similar manner as described for the sidewall tiles, the front wall tiles are chamfered on both the top and bottom edges. The chamfer may extend over the full length of the tile or terminate short of the tile ends.
In some embodiments, the sidewall tiles, the front tiles and the rear tiles comprise a tongue and groove feature. The tongue is normally on the upper edge of the tile and the groove in the lower edge although the position of these two features may be reversed. In an alternative embodiment, vertically adjacent tiles may overlap each other. Other terms for an overlap are ship-lap, cleated-lap and flange.
Tile Composition
The first and second sidewall tiles and the rear and front wall tiles are of a synthetic or natural material. Examples of synthetic materials include polymeric materials and ceramic or porcelain materials. Examples of natural tiles are stone, marble and granite.
Ceramics are generally made by taking mixtures of clay, earthen elements, powders, and water and shaping them into desired forms. Once the ceramic has been shaped, it is fired in a high temperature oven such as a kiln. Often, ceramics are covered in a glaze. An exemplary composition for a ceramic the is described in U.S. Pat. No. 6,127,298 A.
Acrylic or polyester polymeric resins are particularly suitable for synthetic tiles especially those based on polymethylmethacrylate or unsaturated polyester. Combinations of polymethylmethacrylate and unsaturated polyester also have utility. Typically, the resin comprises from 45 to 80 volume fraction percent of polymethylmethacrylate or unsaturated polyester and from 25 to 55 volume fraction percent of inorganic filler particles distributed evenly throughout the resin. Polymethylmethacrylate (PMMA) arises from polymerization of methylmethacrylate. Quartz may also be a component of the polymeric tile materials for example a PMMA/quartz blend. These synthetic resins can be cast or molded and cured to produce a sheet structure suitable for tiles. Exemplary polymeric materials used in solid surfaces are available under the tradename CORIAN®, HI-MACs®, WILSONART®, STARON®, KRION®, SILESTONE®or CAMBRIA®.
Preferably the first and second sidewall tiles and the rear and front wall tiles are “wood workable”. By this is meant that the tiles can be easily cut with graphite tipped tools. A synthetic (polymeric) tile having a Mohs hardness of from 1 to 4, or even 1.5 to 3.5, is deemed to be wood workable.
The first and second sidewall tiles and the rear and front wall tiles are affixed to the wall by adhesive, cement or some other bonding means.
Assembling the Wall Tiles
The wall tiles are assembled using techniques well known to those skilled in the art but are summarized as follows. A backwall tile is the first to be installed, followed by side wall tiles. The backwall tile has dado grooves on both ends the sidewall tiles fit into. The side wall tiles are shimmed to fit tight to the length of the backwall tile to create a tight uniform vertical corner between tiles. Preferably, the horizontal chamfers along the top and bottom edges of tiles are truncated short of the tile ends, to create symmetric corners with the truncated chamfer ends stacked in vertical alignment.
Preferably, a silicone adhesive is used to bond the tiles to the wall.
Design Options
Various design options provide differing advantages.
A first option, as shown in
In a third option, the rear tiles have no dados and the chamfers are full length. The sidewall tiles can be scribed and cut to fit any backwall tile. The advantage here is also that there is no need to adjust the wall to ensure that it is plumb.
