FIELD OF THE INVENTION

The present invention relates to sander vacuum nozzle attachment also known as a dust wing adapter.

BACKGROUND OF THE INVENTION

Sanding is a crucial step in any finishing project as it plays a vital role in determining the final outcome of the finished project. Many people opt for orbital/vibrating sanders to achieve a high-quality finish before applying paint or stain. However, sanding generates a lot of dust that can be a problem for both the worker and the surrounding environment. Many manufacturers have attempted to address this problem by adding dust collection bags to their sanders.

However, these bags tend to have holes in the sandpaper, which reduces its lifespan, and despite their presence, most of the dust still remains free to contaminate other surfaces and requires additional cleaning. To address this issue, a need for a more efficient and effective way of capturing dust from orbital/vibrating sanders was identified. The development of the sander vacuum nozzle attachment fulfills this need, providing a solution to the dust problems caused by sanding.

SUMMARY OF THE INVENTION

To achieve the above and other objectives, the present invention provides for a device (also known as a dust wing adapter) that captures dust while sanding by attaching to a sander and a vacuum system. It comprises of a hollow body with a central intake aperture that attaches to the dust bag mount of the sander and an outlet aperture that attaches to the suction hose of the vacuum system. The device also features a pair of wings that are placed adjacent to the sanding head and to the work surface. Each wing has multiple wing intake apertures which allow dust to be drawn into the hollow body by the vacuum system. The hollow body also has a tubular central portion with the central intake aperture at the front end and the outlet aperture at the rear end. The pair of wings are coupled to each side of the hollow body and are hollow with a hollow interior that communicates with the interior of the hollow body to allow air to flow through.

The attachment comprises a hollow body with central intake aperture and an outlet aperture, and a pair of wings. The central intake aperture is connected to the dust bag mount of a sander, while the outlet aperture is connected to a suction hose of a vacuum system. The pair of wings are placed adjacent to the sanding head and include wing intake apertures that capture the dust and direct it into the hollow body, where it exits through the outlet aperture before being collected by the vacuum system. The wings also have scooped apertures, which induce a more laminar flow of air. This device can be used with an orbital sander or a mouse sander and a vacuum system such as a shop vac.

DESCRIPTION OF THE INVENTION

The present invention is directed to a dust wing adapter (herein described as the “invention”) 100. The invention 100 may comprise a tubular body 200 having a proximal end 204 and a distal end 202, a slot 210, and a tab 220. The invention 100 may be operable to adapt the fit of a sander vacuum nozzle attachment 910 to a sander 900. The distal end 202 of the tubular body 200 may couple to a dustbag mount 904 of the sander 900. The proximal end 204 of the tubular body 200 may couple to a sander coupler 918 of the sander vacuum nozzle attachment 910.

The sander vacuum nozzle attachment 910 may be a device that directs dust produced by the operation of the sander 900 into a vacuum system. The sander vacuum nozzle attachment 910 may ordinarily couple directly to the dustbag mount 904 of the sander 900. A suction hose of the vacuum system may further couple to a vacuum system coupler 914 of the sander vacuum nozzle attachment 910. The sander vacuum nozzle attachment 910 may draw the dust through the dustbag mount 904 and through a pair of wings 916 positioned proximal to a sanding head 908 of the sander 900. When a mismatch exists between the size or shape of the dustbag mount 904 and the size or shape of the sander coupler 918, one (1) of a family of adapters may be inserted between the dustbag mount 904 and the sander vacuum nozzle attachment 910 to adapt the fit. A preferred embodiment of the invention 100 selected from the family of adapters is presented herein.

As a non-limiting example, the sander vacuum nozzle attachment 910 that is the subject matter of co-pending application U.S. Ser. No. 17/532,022, filed Nov. 22, 2021, and titled “Dustless sander vacuum nozzle attachment” may be an embodiment of the sander vacuum nozzle attachment 910 recited herein. The sander vacuum nozzle attachment 910 may also be referred to as a dust wing.

The tubular body 200 may be a hollow cylindrical tube. The distal end 202 of the tubular body 200 may couple with the dustbag mount 904 of the sander 900 by sliding over the dustbag mount 904. The proximal end 204 of the tubular body 200 may couple with the sander coupler 918 of the sander vacuum nozzle attachment 910 by sliding into the sander coupler 918.

The distal end 202 of the tubular body 200 may comprise the slot 210. The slot 210 may be operable to facilitate the coupling of the invention 100 to the sander 900. As a non-limiting example, the slot 210 may enable compression of the distal end 202 of the tubular body 200 by a hose clamp 932 tightened around the tubular body 200. The compression of the tubular body 200 may hold the tubular body 200 onto the dustbag mount 904. As a further non-limiting example, the dustbag mount 904 may comprise a guide pin 942 that may engage the slot 210 in order to prevent rotation of the invention 100 relative to the dustbag mount 904. As a further non-limiting example, the dustbag mount 904 may comprise a set screw aperture 944. A set screw may be coupled to the dustbag mount 904 after passing through the slot 210 in order to retain the invention 100 to the dustbag mount 904, prevent rotation of the invention 100 relative to the dustbag mount 904, or both.

The tubular body 200 may comprise the tab 220 located on the proximal half of the tubular body 200. The tab 220 may be operable to engage a coupling aperture 946 located on the sander coupler 918 of the sander vacuum nozzle attachment 910. Engaging the tab 220 with the coupling aperture 946 may retain the invention 100 to the sander vacuum nozzle attachment 910, may prevent rotation of the invention 100 relative to the sander vacuum nozzle attachment 910, or both.

The outside diameter of the tubular body 200 may be smaller than the inside diameter of the sander coupler 918 on the sander vacuum nozzle attachment 910 such that the tubular body 200 may slide into the sander vacuum nozzle attachment 910. The inside diameter of the tubular body 200 may be larger than the outside diameter of the dustbag mount 904 on the sander 900 such that the tubular body 200 may slide over the dustbag mount 904.

The tab 220 on the tubular body 200 may be smaller than the coupling aperture 946 on the sander vacuum nozzle attachment 910 such that the tab 220 may engage the coupling aperture 946. Specifically, a tab length measured in a longitudinal direction may be smaller than the longitudinal length of the coupling aperture 946 on the sander vacuum nozzle attachment 910 and a tab width measured tangentially may be smaller than the tangential width of the coupling aperture 946 on the sander vacuum nozzle attachment 910.

In some embodiments, a slot length measured in a longitudinal direction may be up to one-half (½) of the longitudinal length of the tubular body 200. In some embodiments, a slot width measured tangentially may be wider than the guide pin 942 or the set screw aperture 944 of the dustbag mount 904 on the sander 900.

In use as illustrated in FIG. 7, the invention 100 may be coupled to the sander 900 and to the sander vacuum nozzle attachment 910 to adapt the fit of the sander 900 to the sander vacuum nozzle attachment 910. The invention 100 may be coupled to the sander 900 by sliding the distal end 202 of the tubular body 200 over the dustbag mount 904 of the sander 900. The invention 100 may be retained to the sander 900 and/or prevented from rotating by using the hose clamp 932, the guide pin 942, or the set screw. The invention 100 may couple with the sander vacuum nozzle attachment 910 by sliding the proximal end 204 of the tubular body 200 into the sander coupler 918 of the sander vacuum nozzle attachment 910 until the tab 220 engages the coupling aperture 946.

The exact specifications, materials used, and method of use of the invention 100 may vary upon manufacturing. The foregoing descriptions of specific embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching.
