Benefits of technology

The present invention aims to achieve several technical benefits. Firstly, it provides the operator with full visibility of the grinding bit without using a shroud. Secondly, it allows for easy replacement of the grinding bit without detaching the dust collection attachment from the grinder. Lastly, the invention provides uniform airflow around the full girth of the grinding bit through a minimally restrictive air flow path.

Problems solved by technology

Hand held tools create dust and debris.
Rotary grinders, in particular, create large amounts of fine dust.
The dust created can be a health hazard.
The dust created is irritating to the lungs and eyes of people and animals and can trigger asthma attacks.

Embodiment Construction

[0016]The tool dust control attachment 1 is comprised of a tube 10 having a first end 15 and a second end 20. There are openings 18 and 19 at each end of tube 10 to allow passage of dust through the tube. The attachment 1 further has a mounting tab 7, which is used to secure the too dust control attachment 1 to grinder 2. At the first end 15 of the attachment 1 is an opening 18 adapted to collect dust dispersed by the grinding bit 5 of the rotary tool 2. The second end 20 of the tube 10 is adapted to connect to a source of vacuum, embodied as an electric vacuum cleaner 3 as shown in FIG. 1B. As seen in FIG. 1A, hose 4 fluidly connects the tool dust control device 1 to the vacuum cleaner 3 at vacuum connection 21.

[0017]Though the invention is described being assembled to a rotary grinder 2, it is not to be limited to only being compatible with a rotary grinder 2. The tool dust control attachment can be adapted to routers, oscillating multi-tools, or any other tool that creates dust. ...

Abstract

A tool accessory is disclosed comprising a tube and capable of attachment to the body of a tool (for example, a rotary grinder) by means of a mounting tab. The tube has a first end with an opening positioned proximate to the source of dust created by the tool. The second end of the tube is adapted for connection to a vacuum source. The opening collects substantially all of the dust from the tool, but does not obstruct the view of the grinding bit.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit under 35 U.S.C. §119 of U.S. Provisional Application Ser. No. 61 / 922,966, filed Jan. 2, 2014, which is incorporated by reference herein in its entirety.FIELD OF INVENTION[0002]The present invention relates to hand held tool accessories, specifically to accessories that collect air born particles created when abrasive stones or bits are used to grind softer materials.BACKGROUND OF THE INVENTION[0003]Hand held tools create dust and debris. Rotary grinders, in particular, create large amounts of fine dust. The dust is inhaled and deposited in the eyes and on the skin of people and animals in the immediate area of the grinding operation. The dust created can be a health hazard.[0004]In recent years the use of rotary grinders has become a preferred method of trimming and buffing nails. Particularly in the pet grooming industry, groomers are using rotary grinders in increasing numbers. There is a concern abou...
