FIELD OF THE INVENTION

The present invention generally relates to a random orbital sander. More specifically, the present invention relates to a sanding tool attachment to a random orbital sander in order to sand a plurality of surfaces simultaneously.

BACKGROUND OF THE INVENTION

A sander is a power tool used to smooth surfaces by abrasion with sandpaper. Sanders have a means to attach the sandpaper and a mechanism to move it rapidly contained within a housing with means to hand-hold it or fix it to a workbench. There are many different types of sanders for different purposes. Multi-purpose power tools and electric drills may have sander attachments. Often times, user may only need to sand a single surface which can be done efficiently with electric sanding tools such as random orbital sanders. Current random orbital sanders can be used for a multitude of errands from polishing a car to grinding a wall. However, there are instances where a user can sand down multiple surfaces that are near each other at once (ex; an edge grain and a face grain of adjacently positioned clapboards). This opportunity can cut down on work time significantly. Current sanders do not provide a solution for grinding orthogonal surfaces simultaneously though the tools are capable of doing so.
An objective of the present design is to provide the user with a sanding tool attachment that may be attached to a random orbital sander. The sanding tool attachment provides the user with a tool fastening feature so that the present invention can be attached to a random orbital sander. The sanding tool attachment also provides the user with two other fastening features so that the present invention can secure a round sanding pad and a rectangular sanding strip. More specifically, the round sanding pad, the rectangular sanding strip, and the sanding tool attachment create a pair of functional surfaces that allow the user to sand orthogonal surfaces simultaneously.

DETAIL DESCRIPTIONS OF THE INVENTION

All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.
The present invention is a sanding tool attachment that is utilized within a random orbital sander to sand a plurality of surfaces simultaneously. More specifically, the present invention enables the user to attain a flat sanding surface and a lateral sanding surface so that orthogonal surfaces can be simultaneously sanded. For example, the present invention can be utilized to simultaneously sand an edge gain surface of an arbitrary clapboard and a face grain surface of adjacent clapboard. In reference to FIG. 1-4, the present invention comprises an annular attachment body 1, a plurality of dust extraction holes 6, a tool fastening feature 7, a primary hook fastener feature 8, and a secondary fastener feature 9.
In reference to FIG. 1-2, the annular attachment body 1 is a platform that attaches to a sanding pad of the random orbital sander. The annular attachment body 1 may be constructed of a sturdy and semi-rigid material such a hard rubber so that the annular attachment body 1 is able to function similar to the sanding pad of the random orbital sander. The height of the annular attachment body 1 is determined upon manufacture requirements and industry standards to optimize the potential sanding projects. For example, the height of the annular attachment body 1 can be ⅜ of inches to precisely match with the standard ⅜ inches thickness of a clapboard. The
In reference to FIG. 1, the annular attachment body 1 comprises a first base wall 2, a second base wall 3, a lateral wall 4, and a central axis 5. The first base wall 2 and the second base wall 3 are oppositely positioned of each other about the lateral wall 4 thus delineating a cylindrical shape. The first base wall 2 is concentrically positioned to the second base wall 3, wherein the first base wall 2 is perpendicularly positioned to the lateral wall 4, and the second base wall 3 is perpendicularly positioned to the lateral wall 4.
In reference to FIG. 3, the first base wall 2 is perimetrically connected to the lateral wall 4 so that the tool fastening feature 7 is able to integrate onto the first base wall 2. In other words, the tool fastening feature 7 attaches the first base wall 2 to the sanding pad of the random orbital sander. Preferably, the tool fastening feature 7 is a loop fastening feature to accommodate an existing hook fastener system that is premanufactured into the sanding pad of majority of the random orbital sanders. However, the tool fastening feature 7 can also be a screw fastener, peal and stick type adhesive fastener, or any other type of fastener that enables the mounting of the annular attachment body 1.
In reference to FIG. 4, the second base wall 3 is perimetrically connected to the lateral wall 4 so that the primary hook fastener feature 8 can be integrated onto the second base wall 3. In other words, the primary hook fastener feature 8 enables the existing round-sandpaper to be attached to the annular attachment body 1 through a premanufactured loop fastener system of the existing round-sandpaper. As a result, the present invention provides the flat sanding surface through the second base wall 3 so that the user can use the existing round-sandpaper to sand a primary flat surface.
Furthermore, a diameter of the first base wall 2 is equal to a diameter of the second base wall 3 thus ensuring the precise alignment of the annular attachment body 1 in between the sanding pad of the random orbital sander and the existing round-sandpaper.
In reference to FIG. 2, the plurality of dust extraction holes 6 is radially distributed around the central axis 5 and traverses from the first base wall 2 to the second base wall 3. Furthermore, each of the plurality of dust extraction holes 6 is oriented perpendicular to the first base wall 2 and the second base wall 3. Due to the positioning of the plurality of dust extraction holes 6, the present invention is able to maintain functionality of the dust collection system that is generally premanufactured into the random orbital sander. For example, the plurality of dust extraction holes 6 are able to extract majority of the dust particle that are created during a sanding process and redirect them away from the sanding surface.
In reference to FIG. 3-4, the secondary fastener feature 9 being integrated onto the lateral wall 4. Preferably, the secondary fastener feature 9 is a secondary hook fastening feature to accommodate a premanufactured loop fastener system that is into the existing sandpaper. More specifically, the user can attach a premanufactured loop fastener system of a rectangular sanding strip to the lateral wall 4 through the secondary hook fastening feature. The rectangular sanding strip can be measured and cut from standard sandpaper sheets or can be manufactured to exact height of the annular attachment body 1. In other words, the present invention provides the lateral sanding surface through the lateral wall 4 so that the user can use the rectangular sanding strip to sand a secondary flat surface that is orthogonal to the primary flat surface. However, the present invention can also be manufactured without the secondary fastener feature 9 to accommodate a peal and stick type adhesive fastener that is also premanufactured into some of the sandpaper.
In alternate embodiment of the abrasive paper that is compatible with the present invention, the abrasive paper comprises a circular body with a first strip and a second strip positioned on a planar surface shown in FIG. 5. The first strip and the second strip are attached tangentially to the circular body. The first strip is also oriented parallel to the second strip. Furthermore, the total length of the first strip and the second strip together is configured to be similar to the circumference of the annular attachment body 1. The abrasive paper further comprises a first surface and a second surface. The first surface is integrated with a loop fastener system that allows the first surface to attach to the second base wall 3 and the lateral wall 4. The second surface is manufactured as the abrasive surface of any grit size. As a result, the loop fastener system is able to attach to the first strip and the second strip to the secondary hook fastener feature 10 and the circular body to the primary hook fastener feature 8.
In another alternate embodiment of the abrasive paper that is compatible with the present invention, the abrasive paper may comprise a plurality of slits and a circular structure that further comprises a first surface and a second surface as seen in FIG. 6. The first surface is integrated with a loop fastener system that allows the first surface to attach to the second base wall 3 and the lateral wall 4. The second surface is manufactured as the abrasive surface of any grit size. The plurality of slits is radially positioned around the abrasive paper and partially traverse from an outer edge of the abrasive paper to the center. As a result, the loop fastener system is able to attach to the circular structure to the primary hook fastener feature 8. The plurality of slits defines a plurality of strips, wherein the plurality of strips can be folded and attached to the secondary hook fastener feature 10.
In another alternate embodiment of the abrasive paper that is compatible with the present invention, the abrasive paper may comprise a cap in which further comprises a first surface and a second surface. The first surface is integrated with a loop fastener system that allows the first surface to attach to the second base wall 3 and the lateral wall 4. The second surface is manufactured as the abrasive surface of any grit size. Once the cap is slide onto the annular attachment body 1, a round section of the cap is attached to the primary hook fastener feature 8, and a rim section of the cap is attached to the secondary hook fastener feature 10.
