The invention relates to spacers for use in tiling, more particularly to a spacer that can also be used as a packing shim.
The process of laying tiles on surfaces such as walls, floors, or worktops generally involves positioning individual tiles in horizontal rows onto a surface primed with some form of adhesive. Tiles are laid with gaps between adjacent tiles, and this gap is later filled with grout to create a waterproof surface. For aesthetic reasons, these gaps between tiles must be kept uniform in width. Any misalignment of a tile affects the appearance of the tiled surface as a whole.
Tile spacers are generally used while the tiles are being positioned to provide a uniform gap between adjacent tiles. Conventional tile spacers are usually in the form of a cross shape, with four arms of uniform length, width, and depth. These spacers are usually laid at the intersection defined by four tile corners and support the tiles while the adhesive is setting. Once the tile adhesive has set, the spacers are removed either by hand or with pliers prior to the application of grout in the gaps.
Removal of tile spacers prior to grouting is important. If grout is applied on top of a tile spacer, it will not adhere as effectively. Removing conventional tile spacers can be a difficult and time consuming job.
The bottom row of tiles is often laid next to a surface which is perpendicular to the tiled surface. Wall tiles, for example, may be laid with the bottom row next to a floor or a worktop, and floor tiles may be laid next to a wall or skirting board. For aesthetic reasons, this bottom or end row of tiles must also be laid along a straight line. When tiling a wall, the gap between the underside of the lowermost row of tiles and the adjacent surface must be packed in order to support the entire set of tiles until the tile adhesive has set, otherwise the tiles are at risk of slipping. When tiling a floor, the gap between the edge of the end row and the adjacent wall or skirting must also be packed to ensure that all rows of tiles maintain their position until the adhesive has set.
Floors and other surfaces are invariably not perfectly straight, and the distance between the edge of the bottom or end tile and the surface perpendicular to the tile is likely to vary along the length of the intersection of the two perpendicular surfaces. Even if the perpendicular surface is perfectly straight, the edge of the tile may be uneven, as it often is with hand made tiles. The arms of conventional tile spacers all have uniform length, width, and depth and are, therefore, not used for packing the gap between this bottom or end row of tiles and the adjacent surface. To pack this gap, a tiler will use a variety of materials, such as a combination of matchsticks and folded pieces of cardboard of varying depth wedged in between the tile edge and the surface.
It would be desirable to provide an improved tile spacer device that can also be used to accurately pack the end or bottom row of tiles.
One aspect of the invention provides a device suitable for use as either a tile spacer or a packing shim as specified in claim 1.
A further aspect of the invention provides a method for tiling a surface as specified in claim 10.
Preferred aspects of the invention are specified in the dependent claims.
The present invention provides a dual purpose removable tile spacer and packing shim. This device enables a tiler to accurately space tiles, as well as easily and accurately support a bottom or end row of tiles using just one product.
Various objects and advantages of this invention will become apparent to those skilled in the art from the following detailed description of the preferred embodiments, when read in light of the accompanying drawings.
With reference to
The desired spacing between tiles varies according to the type of surface, size of tile, as well as the personal preference of the tiler. The size of the spacer, and hence width w, may be modified to produce a variety of different sized spacers suitable for various different tiling jobs.
Each arm has a substantially flat bottom edge for positioning against a substantially flat surface to be tiled. The bottom edge of each arm resides in the same plane (see
The depth of each arm is defined as the distance between a top surface 10t, 12t, 14t, 16t1 and 16t2 and a base 28 of each arm. In the preferred embodiment, three of the arms 10, 12, and 14 each provide one of three different depths d1, d2, and d3, and one arm 16 comprises two portions each with a different depth d4 and d5. As each arm has a different depth, the top surfaces of all the arms do not reside in a common plane. The depth of the arms decreases incrementally. For example, in a device suitable for wall tiling, the different depths d1 to d5 are 5 mm, 4 mm, 3 mm, 2 mm, and 1 mm respectively.
An alternative embodiment is illustrated in
With reference to
The surface 38 adjacent to the bottom row of tiles is uneven. To support the bottom row of tiles, the device 1 is used as a packing shim 44, and one of the four arms 10, 12, 14, or 16 is placed into the gap between the bottom tile edge 40 and the surface 38. The four arms provide different depths d1 to d5. The particular arm used will depend on the depth to be packed. Arm 16 has two possible depths d4 and d5 depending on how far into the gap the arm is pushed.
More than one device 1 can be stacked upon each other in order to create more varied depths for packing. This is illustrated in
Dual purpose tile spacers and packing shims are provided in a plurality of colors and finishes, including white, transparent, and translucent. White, transparent, or translucent spacers may be preferred if a tiler does not intend to remove the spacers prior to the application of grout.
A range of spacers, each one of the range having a different width w, is provided, the range of widths w providing for differently sized gaps between adjacent tiles. Tile spacers are commonly available with widths w of 2 mm, 3 mm, 4 mm, 5 mm, and 7 mm. In a preferred embodiment of the invention, each different width of the tile spacer device of the invention is available in a different color. For example a 2 mm spacer may be black in color, a 3 mm spacer may be red, and a 4 mm spacer may be blue. Color coding the spacers assists the tiler in identifying the correct size spacer for a particular tiling job and also aids removal of the spacers after tiling, as the colored spacers stand out from the background, especially on a white surface.
In accordance with the provisions of the patent statutes, the principle and mode of operation of this invention have been explained and illustrated in its preferred embodiments. However, it must be understood that this invention may be practiced otherwise than as specifically explained and illustrated without departing from its spirit or scope.
