System and method for capturing dust created by rotary tool attachments

Abstract

A system and method are provided for capturing dust created from a work surface by a rotary tool attachment. A shield is comprised of a ridged shroud and a flexible skirt. The shroud is configured to be coupled to a rotary tool, and to either fully enclose or partially expose the rotary tool attachment. The shroud has a plurality of air inlets, a first opening, and a second opening through the top surface of the shroud. The first opening receives a mechanical driveshaft of the rotary tool and the second opening is coupled to an external vacuum source. The flexible skirt is coupled to a perimeter of the shroud and extends downward from above the top surface of the shroud and is configured to contact the work surface.

AI Technical Summary

Benefits of technology

The invention is a shield for capturing dust created from a work surface by a rotary tool attachment. The shield has a shroud with air inlets and a flexible skirt that extends downward from the shroud to contact the work surface. The shield can be used with various types of rotary tools and vacuum sources. The invention is not limited to the specific structure and acts described in the preferred embodiments, but also includes any and all structures, materials, or acts that perform the same function.

Problems solved by technology

The removal of flooring tile is a dirty and time-consuming process.

However, this process usually results in a large amount of dust and debris that is ejected into the ambient air.

In turn, this requires a substantial amount of preparation time to protect surrounding areas from being contaminated with dust.

Additionally, the health of individuals in those areas may be negatively affected by the dust.

Furthermore, environmental regulations may prohibit the escape of the removed dust into the atmosphere.

However, there are significant drawbacks with these designs.

First, the location of the vacuum attachment may not be positioned to maximize the capture of the dust.

Second, the tube that couples the vacuum to the housing does not allow the tool to reach certain places, such as in corners and underneath cabinets.

Third, the durability of many products on the market is suspect.

Fourth, the cylindrical shape of the housing does not allow for the rotary tool attachment to reach against walls.

Fifth, the products may clog with pieces of debris or may strain the vacuum motors, which reduces the useable life of the vacuum.
