AI Technical Summary

Benefits of technology

Enables accurate and efficient identification of surface levelness to within a desired tolerance, reducing the risk of damage during installation by providing clear visual indicators of high and low areas.

Problems solved by technology

Cracking, shifting or chipping of the stonework can be expensive and time-consuming to correct.
Accordingly, installations have become increasingly technically difficult and require a higher degree of precision to prevent damage to the large-format slabs both during and after installation.

Embodiment Construction

[0062]In a stone slab installation, such as for a countertop or floor, a conventional level tool (e.g., spirit or bubble level) can be used across two different dimensions (e.g., length and width) of a support surface (in the case of flooring) and / or the slab surface itself (in the case of a countertop). The surface can accordingly be leveled by removing high areas and filling low areas and / or applying a self-leveling underlayment compound. The slab can also be leveled by insertion of shims and / or removal of areas of the support surface (e.g., cabinetry). These methods work sufficiently well for smaller and / or thicker slabs because the slabs can withstand more tension without cracking. However, a conventional level tool is insufficient to measure the surface tolerance requirements for large-format (e.g., large area) slabs and / or slabs having an intricate or complex form (e.g., an L-shaped countertop).

[0063]Another conventional level tool includes a laser projected in a plane over th...

Abstract

A leveling system for identifying high and low areas of a surface relative to a reference plane to within a desired tolerance. A light source emits light in a level plane at a height above the reference plane. Several depth-indicator targets rest on the surface to be measured in an upright manner and are struck by the light in the level plane. Each of the depth-indicator targets indicates, based on color, whether the surface at that surface location is high, low, or level based on the location at which the light strikes the depth-indicator target. The color emitted by the target can be from a fluorescing layer of the target or light signals on the target controlled by a light-detecting receiver. A user can then quickly identify problem areas of the surface that need to be adjusted (e.g., raised or lowered).

Description

PRIORITY[0001]This application is a division of U.S. application Ser. No. 16 / 270,507, filed Feb. 7, 2019, which application claims the benefit of U.S. Provisional Application No. 62 / 628,861 filed on Feb. 9, 2018, the entirety of each of the above is hereby incorporated by reference and should be considered a part of this specification.BACKGROUNDField[0002]This disclosure is directed to systems, apparatus, and methods for leveling a surface for purposes of construction, flooring, cabinetry, surveying and similar activities.Related Art[0003]In the stone slab industries (e.g., granite, quartz, marble, ceramics, and other types of natural and synthetic stone tiles, slabs, countertops, etc.), the importance of accurate and robust installations is paramount. Cracking, shifting or chipping of the stonework can be expensive and time-consuming to correct. In addition, modern large-format slabs used in flooring installations are thinner (e.g., ¼ inches thick or less) and / or larger (e.g., 15 i...
