Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application incorporates by reference and claims priority to U.S. Provisional Application 61/698,631 filed on Sep. 8, 2012.

BACKGROUND OF THE INVENTION

The present subject matter relates generally to devices and methods for polishing and buffing various surfaces.

There are a wide variety of surfaces that require polishing and/or buffing. For example, granite countertops, leather shoes, purses, furniture, stainless steel sinks, silverware, car seats, metal automotive grills, automotive hubcaps, and automotive paint, among others, require regular polishing. However, each surface requires a different polishing tool or cloth, along with a different polishing solution. Further polishing these various surfaces is both time consuming and laborious, if not physically challenging.

Conventional rotary buffing tools are typically designed for one purpose. For example, electric shoe polishers, which are largely ineffective as they only buff the top surface of the shoe, are only designed to polish shoes. Similarly, electric buffing tools for automobiles are designed for a particular surface. For example, one buffing tool may be suitable for buffing the paint surface of automobiles, whereas a different buffing tool is needed to polish or buff the metallic hubcaps of the automobile. As a result, polishing the various surfaces of an automobile, including paint, metal, and plastic, requires various polishing devices and materials. Further, many polishing devices cannot access many areas of an automobile to properly polish the hard to reach areas, including the grill, side panels, headlight area, side mirrors, doors, door handles, trunk area, and recessed light, among others.

Accordingly, there is a need for polishing devices that efficiently polishes a variety of items and materials.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a side view of the presently disclosed polishing device 10 in connection with an electric drill. In an embodiment, the polishing device 10 comprises an adaptor 12, as shown in FIGS. 2-3. The adaptor 12 includes a conical body 16 including a first body end 18 and a second body end 20, wherein a diameter of the second body end 20 is greater than a diameter of the first body end 18. The conical shape allows a user to polish objects having areas that are hard to access, such as those having small openings and crevasses. FIG. 4 shows a front view of the adaptor 12, wherein the first body end 18 has rounded edges. The rounded edges of the first body end 18 help to prevent the polishing device 10 from scratching or damaging the object and/or material being polished, even in a situation in which a user applies additional force to the polishing device 10.

As shown in FIG. 5, the adaptor 12 also includes a drill bit including a shank 14 configured to engage with a chuck of an electrical drill, wherein the drill bit extends from the second body end 20 of the conical body 16. As shown in FIGS. 2-3, the shank 14 may be a hex-shaped shank 14. Although, any suitable drill bit having any suitable shape of the shank 14 may be used to connect the adaptor 12 to the electric drill such that the adaptor 12 rotates upon activating the electric drill. The drill bit may be made by injection molding of a polypropylene plastic with an embedded zinc-plated shank 14. Of course, alternative construction techniques may be used.

As shown in FIG. 6, the polishing device 10 also includes a first polishing pad 24 surrounding an outer surface of the conical body 16. The first polishing pad 24 includes an outer surface 32 and an inner surface 34, wherein the inner surface 34 is in contact with the conical body 16 of the adaptor 12. The first polishing pad 24 also includes an elastic strap 26 spanning an opening 36 of the first polishing pad 24 such that, when fitted to the adapter 12, the elastic strap extends from one portion of the second body end 20 to another portion of the second body end 20 to secure the first polishing pad 24 in place on the adapter 12. For example, the elastic strap 26 may extend generally along the diameter of the second body end 20. The first polishing pad 24 may include more than one elastic strap 26 to further secure the first polishing pad 24 to the conical body 16 of the adaptor 12.

To mate with the elastic strap 26, the second body end 20 of the conical body 16 may include at least one channel 22 for receiving the elastic strap 26 of the first polishing pad 24 such that the first polishing pad 24 remains secure on the conical body 16. As shown in FIGS. 5-6, in the example provided, the second body end 20 includes two channels 22 for receiving the elastic strap 26. As shown, the channels 22 are rectangular divots located in the edge of the second body end 20.

The first polishing pad 24 may include a polymer-based foam, such as a seamless reticulated polyester foam, which may have a thickness between 0.5 inches and 3 inches, including 0.5 inches and 3 inches. The polymer based foam may be used to polish certain objects and materials, such as for automobile detailing of both metal and paint. The seamless design may be accomplished by router cutting or injection molding during the manufacturing process.

In another example, the outer surface 32 of the first polishing pad 24 includes polishing fibers and the inner surface 34 of the first polishing pad 24 includes a backing to which the polishing fibers adhere. For example, the first polishing pad 24 may include a microfiber material that is typically used in automotive detailing. Alternatively, the first polishing pad 24 may include natural seared wool with a polyester and cotton blend as the backing.

Alternatively, the inner surface 34 of the first polishing pad 24 may include a seamless reticulated polyester foam and the outer surface 32 of the first polishing pad 24 includes polishing fibers. In other words, the first polishing pad 24 may be a foam lined microfiber pad or wool pad with an elastic strap 26 to secure the first polishing pad 24 to the adaptor 12. The microfiber or wool may be attached to a foam backing pad to minimize the impact of the seam of the microfiber pad or wool pad when used with an electric drill. In addition, the use of a foam lined first polishing pad 24 allows the application of various levels of pressure to increase or decrease the cutting level of the first polishing pad 24.

As shown in FIG. 2, the polishing device 10 may include more than one polishing pad 24. For example, the first polishing pad 24 may be a seamless reticulated polyester foam, and the polishing device 10 may further include a second polishing pad 28. The second polishing pad 28 may include an outer surface 38 and an inner surface 40. The outer surface 38 of the second polishing pad 28 may include polishing fibers and the inner surface 40 of the second polishing pad 28 may include a backing to which the polishing fibers adhere. In addition, the inner surface 40 of the second polishing pad 28 may surround the outer surface 32 of the first polishing pad 24.

The first polishing pad 24 and/or the second polishing pad 28 may be color coordinated to indicate a pad suitable for a unique application, which allows a user to apply different waxes or polishing without inadvertently combining chemicals. For example, black first polishing pad 24 may be designated for polishing black shoes with a black shoe polish. A red first polishing pad 24 may be designated for polishing brown shoes with a brown shoe polish. Color coordinating is very important when working with various chemicals that are potentially dangerous when combined.

The disclosed polishing device 10 provides a solution for precision buffing, cutting, polishing, and finishing of detailed parts constructed of various materials including metal, stone, paint, plastic, and glass, among others. In other words, the presently disclosed polishing device 10 enables a user to polish various surfaces with the use of one tool, namely, the polishing device 10.

It should be noted that various changes and modifications to the embodiments described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages. For example, various embodiments of the method and portable electronic device may be provided based on various combinations of the features and functions from the subject matter provided herein.
