The present invention claims priority to U.S. Provisional Pat. App. No. 61/733,893, titled “Systems and Methods for Stripping and/or Finishing Wood Surfaces,” filed Dec. 5, 2012, which is incorporated herein by reference in its entirety.
TECHNICAL FIELDThe present invention relates to systems and methods for stripping and/or finishing wood surfaces. Specifically, the present invention relates to using systems and methods utilizing rotary apparatuses having metal embedded or bonded industrial diamonds to cut, grind, and polish wood surfaces.
BACKGROUNDIt is, of course, generally known to fix imperfections in surfaces of all kinds. Surfaces such as wood, plastic, concrete, or metal are not naturally smooth, shiny, or uniform. The process for fixing imperfections is time consuming, strenuous, and requires many different materials.
For example, it is generally known to use sandpaper to fix imperfections in wood. Sandpaper is an abrasive material that may be used to remove imperfections from a surface or remove an entire layer from a surface by rubbing the sandpaper on the surface.
Sand paper comes in a variety of grit sizes, which refers to the size of the abrasion material embedded in the sand paper. The higher the grit size, the finer the diameter of the abrasion material. Generally, one will start sanding with a coarse material and gradually work up the grit sizes in order to arrive at a smooth, finished surface.
Sandpaper comes in a variety of sizes depending on the size of the imperfection. Sandpaper could be a nine-inch by eleven-inch sheet, a belt for use on belt sanders, a disc for use on rotary sanders, or a sponge for tight places.
Generally, belt sanders can be small handheld devices or large machines that turn a loop of mounted sandpaper. Belt sanders are commonly used on wood during beginning stages of sanding to remove finishing, paint, or other surface materials. However, belt sanders are disadvantageous because they can only be used unidirectionally.
Commonly, rotary sanders are used on wood floor surfaces or other large projects. Rotary sanders may be used in all directions, however, when working on a large project rotary sanders have to pass over the same area multiple times with multiple grit sizes. Sanding an entire room with a rotary sander may take days.
Drum sanders or rotary sanders, whether as large machines or hand held devices, are difficult to utilize quickly and efficiently, especially over a large surface, such as a large room, a deck, or the like. Typically, either a drum sander or a rotary sander may be used to strip one or more layers of paint, varnish, wax or other surface coating from a surface. In a first pass, the grit is typically very abrasive, such as a 32 or 36 grit, for example, in order to remove large amounts and relatively deeply into the wood surface. After the abrasive grit, a second or third pass is typically done with a medium abrasive grit, such as about 60 to 80 grit, for example. After that, a final pass is typically done using a finely abrasive grit, such as above 80, to smooth the wood and prepare the wood to receive paint, stain or another material.
In using sandpaper to abrade a wood surface, it is common to have to change the sandpaper frequently during the process. This is due to wear on the sandpaper. As the sandpaper is utilized, it loses its abrasiveness as the abrasive material rubs off of the sandpaper. Moreover, due to the relative fragility of paper, the sandpaper frequently becomes worn or torn during use.
A need, therefore, exists for an apparatus, system and method for stripping and/or finishing a wood surface that may be accomplished quickly and efficiently. Specifically, a need exists for an apparatus, system and method that may be utilized to strip and/or finish a wood surface without requiring frequent stopping of the apparatus.
Further, a need exists for an apparatus, system and method for stripping and/or finishing a wood surface that may remove paint, stain, varnish, wax, or other surface coating of a wood surface without leaving a large amount of residual material thereon. Still further, a need exists for an apparatus, system and method for preparing a wood surface to receive a paint, stain, varnish, wax, or other material without requiring frequent changing of the abrasive surface.
Similarly, it is also generally known to grind concrete to make it level and smooth. When concrete is poured, the surface is never completely smooth, shiny, or uniform. Frequently, concrete grinders are used to smooth the surface. Concrete grinders are generally very powerful and utilize diamond tools or silicon carbide because of the rough nature of concrete. Normally, concrete grinders are only used on extremely abrasive and tough surfaces such as concrete. It has not been known, prior to the present invention, to utilize apparatuses for grinding concrete on relatively fragile wood surfaces.
A need, therefore, exists for utilizing apparatuses typically known for grinding concrete for stripping and/or finishing wood surfaces, thereby providing quick and efficient preparation of the wood surface to receive paint, stain, varnish, wax, or other finishing material.

Now referring to the figures, wherein like numerals refer to like parts,
The apparatus 10 is known for use in grinding and smoothing concrete. However, in the systems and methods of the present invention, the apparatus 10 may be utilized for stripping and/or finishing hard wood flooring 16, as illustrated in
The present invention may be utilized to strip and/or finish any wood flooring apparent to one of ordinary skill in the art, and the present invention should not be limited as described herein. Specifically, common wood flooring surfaces useful for stripping and/or finishing include solid oak wood panels, bamboo, and other like wood products, and may also include engineered wood flooring, such as made from resins or composites.
As illustrated in
Utilizing the apparatus 10 for stripping and/or finishing hardwood floors is advantageous because the hardwood floor may be completely stripped in a relatively short period of time. Where a hardwood floor might previously have taken days with known sandpaper-laden apparatuses, the entirety of the hardwood floor may be stripped in a fraction of that time. Because the grinding heads 22, as disclosed in more detail below with respect to
As illustrated in
In general, the metal utilized in the metal grinding heads 30, 40, as described above, may be made from any metal apparent to one of ordinary skill in the art. Of course, other materials may be utilized, such as resins, as disclosed below, silicon carbide, or other similar material. In addition, the degree of bond between the metal and the abrasive may be specified depending on the requirements of the hardwood stripping and/or finishing.
It should be noted that although specific grinding heads are shown and described herein, the invention should not be so limited. Any grinding head utilizing an abrasive, such as, for example, industrial diamonds or a similar abrasive, bonded to a rigid material, such as metal, resin, or other like material, may be utilized. In addition, grinding heads of different sizes or for use with different concrete grinders or polishers may be interchanged, such as via use of adapter plates or the like.
The grinding heads described herein may be utilized to strip and/or finish a hardwood floor, and different heads may be utilized depending on the specific needs of the hardwood floors. As mentioned above, different grinding heads may be required depending on the material contained on the hardwood floor surface, the type and hardness of the wood, the unevenness of the hardwood floor surface, or other like parameters. Moreover, the motor 12 of the apparatus 10, as shown herein, may be variable speed. Thus, depending on the effect desired by a user of the apparatus 10, the speed of the motor 12 may be changed to arrive that the effect desired.
The present invention has been generally described with respect to a relatively large rotary grinding apparatus 10, but it should be noted that other apparatuses typically utilized in concrete grinding may be utilized for stripping and/or finishing hardwood floors, such as a handheld rotary grinder 70, shown in
It should be noted that various changes and modifications to the presently preferred 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.
