The invention relates to a device for mounting tiles. In particular, a device for aligning, spacing and pressing tiles that is reusable, easy to handle, has dual spacing width and provide visual access to the intersecting tile corners.
Ceramic or stone tiles, or sheets of mosaic tiles glued to a mesh webbing, are commonly used to cover floors, walls and counters. Each tile or sheet is individually set, spaced apart from other tiles, on an adhesive material. The spacing between tiles or sheets is then filled with grout. It is important that the spacing between tiles is uniform to provide a properly spaced and aligned tile pattern.
A spacer is normally utilized to achieve uniform spacing between tiles. A plurality of spacers is used when tiles are being laid onto adhesive material. A typical prior art spacer is shown in U.S. Pat. No. 2,031,684 issued on Feb. 25, 1936 to F. H. Berger, which discloses a cross shape spacer for defining the four corners of four intersecting tiles. The typical prior art spacer has a depth from ⅛ to {fraction (3/16)} of an inch, which is less than the normal minimum thickness of tiles, ¼ of an inch, and spacing widths of between {fraction (1/16)} to ⅜ of an inch. Prior art spacers of predetermined widths are generally laid onto the adhesive material with four intersecting tiles pushed up against the four corners of the cross shape spacer to achieve uniform spacing of the width of the spacers. Prior to filling the spacing with grout, prior art spacers are removed with a pick or other tools because it sits below the surface of the adjacent tiles and on adhesive material, which is difficult and time consuming. Oftentimes, such prior art spacers are not retrieved and reused in view of the time and effort involved.
The small prior art cross-shape spacer is difficult to handle by the worker and U.S. Pat. No. 5,288,534 issued on Feb. 22, 1994 to B. A. Tavshanjian attempts to redress this problem. The '534 patent discloses a prior art, cross shape tile spacer having a platform wherein cross shapes extend from opposite surfaces of the platform, providing means for handling and removing the tile spacer and for pressing it when laying tiles. Although the tile spacer of the '534 patent is reusable and improves handling, it provides only a predetermined spacing width. Additionally, the platform prevents any visual access to the four intersecting corners of the files to determine proper alignment against the cross shape spacer.
Therefore, there is a need for a reusable tile spacer that is easy to handle, has multiple, or at least, dual spacing width and provide visual access to the intersecting tile corners.
The present invention provides a tile spacer that aligns, spaces and presses tiles that is reusable, easy to handle, has dual spacing width and provide visual access to the intersecting tile corners.
The tile spacer of the present invention comprises a planar horizontal body having two, three or four outer vertical legs around the body. The body has an opening. The legs are aligned with each other to form a straight line, T-shape or cross-shape. Each leg having top and bottom portions, each portion having a different predetermined width for different tile spacing widths.
When tiles are being laid onto adhesive materials, a tile spacer of the present invention is used for each set of four tiles at the four intersecting corners. Depending on the preferred spacing required, either the top or bottom portions of the legs are selected and set between the four corner edges of the tiles. The body provides a planar surface for pressing the corners of the tiles onto the adhesive material for proper alignment. The opening of the body provides visual confirmation that the tiles are properly aligned with respect to the four legs. When the tiles are properly laid onto the adhesive material, the tile spacer of the present invention may be easily removed by placing a finger into the opening and lift the tile spacer from the surface of the tiles.
A preferred embodiment of the present invention has been chosen for purposes of illustration and description and is shown in the accompanying drawings forming a part of the specification wherein:
With reference to the drawings, wherein the same reference number indicates the same element throughout, there is shown in
The tile spacer 10 comprises a planar body 12 having four outer legs 16a-16d around the body 12. The planar body 12 has a center opening 14. The four legs 16a-16d are aligned with each other to form a cross (as shown in FIGS. 3 and 4). Each leg 16a-16d has a top portion 18 and a bottom portion 20 of different widths for different tile spacing widths. For example, the width, w, of the top portion 18 may be ⅛ of an inch and the width, W, of the bottom portion 20 may be ⅜ of an inch. Each leg extends from a surface of the body to a distance, D1 and D2 for the top portion 18 and bottom portion 20, respectively, preferably less than the thickness of the tiles being laid (see FIG. 2). Tiles are generally more than ¼ of an inch thick.
Although the tile spacer 10 shows in
In view of the simple structure of the tile spacer 10 and 10′ of the present invention, the tile spacer 10 can be easily manufactured or molded from plastic at a low cost. The tile spacer 10 may be made from other material such as wood, metal, rubber, etc.
The features of the invention illustrated and described herein is the preferred embodiment. Therefore, it is understood that the appended claims are intended to cover unforeseeable embodiments with insubstantial differences that are within the spirit of the claims.
