Description

CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application No. 61/914,685 filed on Dec. 11, 2013. The above identified patent application is herein incorporated by reference in its entirety to provide continuity of disclosure.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to cleaning appliances. More specifically, the present invention pertains to an improved attachment for rotary floor machines that is configured to clean a floor, the baseboards, and a set of stairs. The present invention is a disc-shaped housing that attaches to the drive system of a rotary floor machine. The housing includes sidewalls that are substantially the height of stair risers of a set of stairs, which allows the present invention to clean the near-vertical surface of stair risers of a set of stairs.
Cleaning a non-carpeted floor is a great way to renew the appearance of a scratched, worn finish without incurring the expense and hassle of completely refinishing the floor. Buffing, for example, is the final step any professional refinishing job, but it can also be done as a solitary process to restore the shine to a dull, lifeless non-carpeted floor, such as hardwood, marble, tile, or linoleum. Buffing will not remove deep scratches or heavy damage, however, it will remove the majority of surface scratches and help protect a floor. Thus, delaying the need to fully refinish or replace the floor. A rotary floor machine is an electrical floor scrubber that is used to clean and maintain non-carpeted floors such as hardwood, marble, or linoleum. They are also known as floor buffers or floor polishers and are used in schools, hospitals, offices and public buildings. Scaled-down versions are available for home use.
However, separate procedures have been conventionally required to clean and polish a set of stairs. Although treads and stair risers can have a dramatic impact on the aesthetic look of a building or house, stair risers, especially of a white or light color are susceptible to scuff marks. Rubber-soled shoes typically transfer black scuff marks that are particularly noticeable. Often typical procedures for cleaning a set of stairs requires heavy manual work. These procedures often require spraying a rag with an all-purpose cleaner and rubbing out markings on a stair riser. Sometimes, additionally it requires using a foam cleaning eraser and rubbing off the remaining scuff marks.
Therefore, cleaning a set of stairs often requires more arduous work than simply using a rotary floor machine. However, the present invention provides a solution for a more convenient method of cleaning a set of stairs. The present invention provides an attachment for rotary floor machines that is configured to clean a floor, baseboards, and both the treads and stair risers of a set of stairs. The rotary floor machine attachment includes a disc-shaped housing with a top surface, a bottom surface, and a sidewall. The top surface of the rotary floor machine attachment includes a circular plate having a mounting flange centrally located that allows for removably attachment to a drive system of a rotary floor machine. The sidewalls are substantially the height of a stair riser in a set of stairs and are configured to clean the vertical surfaces of stair risers and baseboards of a floor. The bottom surface is configured to clean the floor and the tread of a set of stairs.

References are made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the rotary floor machine attachment. For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for cleaning non-carpeted floors, baseboards, and a set of stairs with treads and stair risers. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.
Referring now to FIG. 1, there is shown a side perspective of the rotary floor machine attachment 20 attached to a rotary floor machine 50. The rotary floor machine attachment 20 removably attaches to a rotary floor machine 50 that is configured to clean a floor, baseboard, and a set of stairs having the treads and stair risers. The rotary floor machine attachment 20 is also equipped to handle all other types of procedures such as stripping, scrubbing, polishing and burnishing. The conventional rotary floor machine is an upright, wide-based cleaner with handlebar controls 51 and requires two-handed steering. They have cleaning pads which are rotatably spun by a small motor or drive system 52. The rotary floor machine attachment 20 is a new and improved attachment that is removably attached to the drive system 52 of a rotary floor machine 50.
The rotary floor machine attachment 20 includes a disc-shaped housing 21 with a top surface 22, a bottom surfaces 23, and a sidewall 24. The top surface 22 of the rotary floor machine attachment 20 includes a circulate plate having a mounting flange with means for attaching to the drive system 52. The top surface 22 and the bottom surface 23 are substantially circular-shaped and coplanar to one another. The sidewall 24 extends substantially perpendicularly from the top surface 22 and the bottom surface 23 along the peripheral edges thereof. The housing 21 further includes an interior wall 29 that forms a centrally located open aperture extending from the top surface 22 to the bottom surface 23. The sidewall 24 is substantially sized to the height of stair risers on a set of stairs and are configured to clean the near-vertical surface of stair risers and baseboards of a floor. The sidewall 24 is placed in contact to the near-vertical surface of the stair risers, wherein the drive system 52 will supply power and continuously rotate the sidewalls therealong to remove dirt and scuff marks.
The bottom surface 23 is configured to clean the floor and the tread of a set of stairs. The bottom surface 23 and sidewall 24 further include a plurality of raised spikes 26 that are arranged in a linear configuration to removably secure a floor pad and a sidewall pad for buffing or cleaning. In other embodiments, the bottom surface 23 and sidewall 24 are lined with a different type of fastener to removably secure floor pads and sidewall pads to the surfaces. These fasteners include, but are not limited to hook and loop fasteners and other suitable types of fasteners. The bottom surface 23 and sidewall 24 are preferably composed of a tough and durable polyurethane, however, other embodiments without limitation are composed of other suitable types of durable materials.
Referring now to FIG. 2, there is shown a side perspective of the rotary floor machine attachment 20 removably secured with a floor pad 27 and sidewall pad 28 and attached to a rotary floor machine 50. Rotary floor machine attachment 20 further comprise floor pad 27 and sidewall pad 28 having an interior surface and an exterior surface. The floor pad 27 and the sidewall pad 28 are attached to the bottom surface and sidewall, respectively through the raised spikes aforementioned. The raised spikes engage and nest in the indented portions on the interior surfaces of the floor pad 27 and the sidewall pad 28. The floor pad 27 and the sidewall pad 28, in other embodiments, may also be removably attached with hook and loop fasteners or other suitable types of fasteners. The sidewall pad 28 is a hollow cylindrical surface that substantially fits around the sidewall 24. The floor pad 27 is a circular pad that is placed plush against the bottom surface 23 and is sized to substantially the same size as the bottom surface 23. The floor pad 27, in this particular embodiment, does not include a circular aperture substantially in the middle of the floor pad 27. However, other embodiments of the floor pad 27 further include a circular opening, wherein the circular opening is sized to align with the centrally located open aperture of the housing.
The sidewall pad 28 is configured to clean baseboards and stair risers, while the floor pad 27 is configured to clean floors and the treads in a set of stairs. The sidewall pad 28 is sized to substantially match the height of a stair riser of a set of stairs. The sidewall pad 28 is particularly advantageous as it is configured to remove dirt or scuff marks on the stair risers, which is not particularly handled by a conventional rotary floor machine. The floor pad 27 and the sidewall pad 28 will accrue wear and tear over time, and replacement floor pads 27 and sidewall pads 28 can be removably secured.
The floor pad 27 and the sidewall pad 28 both have respective interior surfaces and exterior surfaces. The interior surfaces are lined with indented portions that align with the raised spikes to removably attach the floor pad 27 and sidewall pad 28 to the sidewall and bottom surface. The exterior surface of the floor pad 27 and sidewall pad 28 are placed in contact with the floor, baseboards, and a set of stairs to remove dirt and scuff marks. Depending on the type of floor care done, the exterior surface of different embodiments of floor pads 27 and sidewall pads 28 are preferably composed of synthetic, blended, natural fibers or microfiber. Certain embodiments of floor pads 27 and sidewall pads 28 are composed of synthetic fibers, which often are used for scrubbing and stripping procedures. Other embodiments use blended fiber or natural fiber, which are best for burnishing, while other embodiments are composed of microfibers, which are meant for cleaning procedures.
Certain floor pads are more efficient than other types for cleaning, polishing, burnishing, buffing, scrubbing and stripping procedures. In general, there is an industry standard color-coding system from light to dark for floor pads that respectively define least least-coarse pads to the most aggressive pads. Buffing pads are lightest in color and remove scuff marks and dirt floors. Cleaning pads are designed to clean a little more aggressively than buffing pads and remove dirt off a floor's surface without removing floor finish. Slightly more aggressive are scrubbing pads that remove the top lawyer or two of wax along with all the scratches and dirt. To remove more coats of wax, users turn to stripping pads which are darker in color. Burnishing pads are the most aggressive type of pad and apply heat and pressure to the floor to remove wax. The floor pad 27 may be color-coded similar to the industry standard. In addition, the sidewall pad 28, which is secured around the sidewall of the rotary floor machine attachment 20, will further comprise a similar color-coding system to align the coarseness of sidewall pad 28 with the floor pad 27.
Referring now to FIG. 3, there is shown a side perspective of the rotary floor machine attachment 20. The interior surfaces 33, 34 of the sidewall pad 28 and the floor pad 27 further include a plurality of indented portions 35 that align with the raised spikes 26 to removably attach the floor pad 27 and sidewall pad 28 to the sidewall 24 and bottom surface. Furthermore, the top surface 22 of the rotary floor machine attachment 20 includes a circular plate 31 having a mounting flange 32 with means for attaching to the drive system 52. The circular plate 31 is sized to substantially align with the top surface 22, wherein the circulate plate 31 is placed in contact and plush on the top surface 22. The mounting flange 32 is centrally located and aligned with the centrally located aperture on housing 21. Different rotary machines have different mechanisms for removably attaching the mounting flange 32. Therefore, the particular means for attachment will depend on the particular rotary floor machine.
Referring now to FIG. 4, there is shown an overhead perspective of the rotary floor machine attachment 20 as removably attached to a rotary floor machine 50 to clean a set of non-carpeted stairs. The bottom surface 23 is configured to care for the tread 60 of a set of stairs. Depending on the type of floor pad 27 removably attached to the rotary floor machine 50, the rotary floor machine attachment 20 is configured to polish, buff, clean, scrub, strip, and burnish the tread 60. The bottom surface 23 is also configured to care for any non-carpeted floor. The sidewall pad 28 is configured to care for the stair risers 25 for a set of stairs. The sidewall pad 28 is pressed against the vertical surface of the stair risers 25 to polish, buff, clean, scrub, strip, or burnish the stair risers 25. The sidewall pad 28 are sized to substantially the same height as the stair risers 25 to remove dirt or scuff marks thereon.
According to the preferred embodiment, the rotary floor machine attachment 20 further provides a method of cleaning the tread and stair risers of a set of stairs comprising the steps of:

- selecting a set of stairs having at least one tread and stair riser for cleaning;
