Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is being filed on Jun. 16, 2021, as a U.S. Patent Application, and claims priority to U.S. Provisional Application No. 63/039,944 filed on Jun. 16, 2020, titled “Tile Leveling System,” which is hereby incorporated by reference in its entirety.

BACKGROUND

Tiles are installed on surfaces such as floors, walls, countertops, and the like. Installers spend a significant amount of time aligning and leveling tiles as the tiles are being placed on an installation surface. Proper alignment and leveling of each tile is important, because if one tile is improperly installed, the error continues in adjacent tiles such that the installed tiles become aesthetically unacceptable, and the tiles need to be re-installed and/or replaced. Replacing or otherwise correcting errors in tile installation is both costly and time-consuming.
In particular, many installation surfaces have a relatively large size and/or defects and imperfections such as dips, ridges, curvatures, out-of-plane or uneven regions. In addition, tiles may be uneven in dimension or varying in size and thickness. Thus, the tiles, if not properly leveled or aligned, will be unevenly installed on the surface out of level or plane. The unleveled tiles installed on a floor surface may additionally cause safety problems. For example, people may trip or fall on the uneven tiles. There is thus a need for a versatile, low-cost, fast, and effective tool for leveling and aligning tiles to be installed on a surface.
