MULTIPLE EMBODIMENTS AND ALTERNATIVES
Turning now to the drawings and, more particularly to FIG. 1, a floor treating system according to multiple embodiments and alternatives is illustrated generally at 100 and includes a bottom portion 110. An embodiment of the bottom portion 110 of the floor treating system 100 is further illustrated in FIG. 2. As shown in FIG. 2, the bottom portion 110 includes a power source 150 with a rotatable drive shaft 200, a floor treating attachment 130, and means for imparting at least two speeds of oscillating motion from the drive shaft 200 to the floor treating attachment 130. The floor treating attachment 130 may be any of a number of conventional floor treating attachments commonly utilized in floor treating systems, such as a carpet cleaning attachment, a tile cleaning brush, a hardwood sanding attachment, a vinyl composition tile (VCT) stripping attachment, or a stone, marble, or terrazzo grinding, sanding, honing, or polishing attachment, for example. In some embodiments, the floor treating attachment 130 may be a rug beating attachment. The power source 150 may be any of a number of conventional power sources commonly utilized in floor treating systems, such as a motor, for example.
Returning to FIG. 1, multiple embodiments of the floor treating system 100 include a housing assembly 140 with a proximal end 142 and a distal end 144. The housing assembly 140 may be manufactured from conventional materials commonly utilized in floor treating system housings including, but not limited to, anodized aluminum, stainless steel, and nickel. The floor treating system 100 may also include a brush cover 120, and the brush cover 120 may be manufactured from conventional materials commonly utilized in floor treating system brush covers including, but not limited to, anodized aluminum, stainless steel, and nickel. The floor treating system 100 may further include a handle assembly 165 with a handle 160 and a handle plate 162. Any electrical wiring may be enclosed in the handle assembly 165 and behind the handle plate 162. Additionally, the floor treating system 100 may include an on and off switch 168, an electrical cord 170, a strain relief 175 on the electrical cord 170, a lifting handle 190, a kickstand 192, and wheels 194, 196, and 197.

The spray system 180 may also include a pump (not shown) and hose assembly (not shown), which may be substantially enclosed in the housing assembly 140. Additionally, the pump may be located between the spray heads 183 and 184 and the distal end 144 of the housing assembly, thereby reducing any leakage of fluid from the spray heads 183 and 184. The pump may also be located between the spray tank 181 and the distal end 144 of the housing assembly the spray tank 181. Also, the spray tank 181 may be sealed, thereby further reducing any leakage of fluid from it.
As illustrated in FIG. 2, in multiple embodiments of the bottom portion 110, the rotatable drive shaft 200 of the power source 150 rotates around an axis of rotation R. In some embodiments, the means for imparting at least two speeds of oscillating motion from the drive shaft 200 to the floor treating attachment 130 comprise a flywheel 210 having an aperture 215 to receive the drive shaft 200, a counterbalance 230 configured to connect to the flywheel 210, and means for connecting the floor treating attachment 130 to the counterbalance 230 at at least two different distances from the axis of rotation R. For example, the means for connecting the floor treating attachment 130 to the counterbalance 230 may be configured to connect the floor treating attachment 130 to the counterbalance 230 at a distance d1 from the axis of rotation R, at a distance d2 from the axis of rotation R, and at a distance d3 from the axis of rotation R. Each distance from the axis of rotation R corresponds to a different speed of oscillating motion that may be imparted from the drive shaft 200 to the floor treating attachment 130. In multiple embodiments, the drive shaft 200 of the power source 150 rotates the flywheel 210 around the axis of rotation R, the rotation of the flywheel 210 provides motion to the counterbalance 230, and the motion of the counterbalance 230 imparts an oscillating motion to the floor treating attachment 130 through the means for connecting the floor treating attachment 130 to the counterbalance 230.
In some embodiments, the bottom portion 110 also includes a counterweight 220, or a number of counterweights 220a and 220b (as shown in FIG. 7), configured to attach to the counterbalance 230. Additionally, the means for connecting the floor treating attachment 130 to the counterbalance 230 may comprise a plug bearing 240, a spacer 250, and a bolt 270, in some embodiments. The plug bearing 240 may have a lip 242 that extends over part of the floor treating attachment 130 to assist in connecting the floor treating attachment 130 to the counterbalance 230, while the remainder of the plug bearing 240 is positioned between the floor treating attachment 130 and the counterbalance 230. In multiple embodiments, the drive shaft 200 of the power source 150 rotates the flywheel 210 around the axis of rotation R, the rotation of the flywheel 210 provides motion to the counterbalance 230, and the motion of the counterbalance 230 imparts an oscillating motion to the floor treating attachment 130 through the plug bearing 240.
As illustrated in FIG. 3, the counterbalance 230 may include apertures 260a and 260b, and, as illustrated in FIGS. 4 and 5, the plug bearing 240 may include apertures 280a-280d. Any of the plug bearing apertures 280a-280d, or any combination of the plug bearing apertures 280a-280d, may be configured to align with any of the counterbalance apertures 260a and 260b, or any combination of the counterbalance apertures 260a and 260b, each alignment corresponding to a different distance from the axis of rotation R to the floor treating attachment 130. Each distance from the axis of rotation R, in turn, corresponds to a different speed of oscillating motion that may be imparted from the drive shaft 200 to the floor treating attachment 130. Also, the bolt 270 may extend through any of the plug bearing apertures 280a-280d and any of the counterbalance apertures 260a and 260b to assist with the connection of the floor treating attachment 130 to the counterbalance 230.
As shown in FIG. 2, for example, the plug bearing aperture 280a may align with the counterbalance aperture 260a, with the bolt 270 extending through the apertures 280a and 260a. This alignment may correspond to the distance d2 from the axis of rotation R and to a speed of oscillating motion that is imparted from the drive shaft 200 to the floor treating attachment 130. The plug bearing aperture 280c may also be configured to align with the counterbalance aperture 260a, with the bolt 270 extending through the apertures 280c and 260a. This alignment may correspond to a different distance from the axis of rotation R and to a different speed of oscillating motion that is imparted from the drive shaft 200 to the floor treating attachment 130. Thus, different speeds of oscillating motion may be utilized during different applications of the floor treating system 100, such as a higher speed when cleaning a floor quickly is desirable and a lower speed when cleaning a floor with less power is desirable, for example.
Returning to FIG. 1, in multiple embodiments of the floor treating system 100, the floor treating attachment 130 may be located at a distance of at least 0.400 inch from the axis of rotation of the rotatable drive shaft of the power source 150. In some embodiments of the bottom portion 110 shown in FIG. 2, for example, the distance d2 may be approximately 0.4375 inch from the axis of rotation R and the counterweight 220 may have a mass between 1946 grams and 1956 grams. In certain embodiments, the distance d1 may be approximately 0.375 inch and the distance d3 may be approximately 0.5625 inch, with the counterweight 220 having a mass between 1946 grams and 1956 grams.
Each distance from the axis of rotation of the rotatable drive shaft corresponds to a different size of orbit of the floor treating attachment 130. For example, in some embodiments, the floor treating attachment 130 may have a diameter of 15 inches and may be 0.375 inch from the axis of rotation, corresponding to an orbit size of 15.75 inches. In other embodiments, the floor treating attachment 130 may have a diameter of 15 inches and may be 0.4375 inch from the axis of rotation, for example, corresponding to an orbit size of 15.875 inches.
Each orbit size corresponds to a different speed of oscillating motion imparted from the drive shaft at a given number of revolutions per minute, and to a different amount of power required to impart that speed of motion. For example, in some embodiments, the floor treating attachment 130 may be 0.25 inch from the axis of rotation of the rotatable drive shaft, corresponding to a 1⁄3 horsepower requirement to impart oscillating motion at 1725 revolutions per minute. In other embodiments, the floor treating attachment 130 may be 0.375 inch from the axis of rotation, corresponding to a 0.5 horsepower requirement to impart oscillating motion at 1725 revolutions per minute. In other embodiments, the floor treating attachment 130 may be 0.4375 inch from the axis of rotation, corresponding to a 0.75 horsepower requirement to impart oscillating motion at 1725 revolutions per minute. In other embodiments, the floor treating attachment 130 may be 0.5 inch from the axis of rotation, corresponding to a 1 horsepower requirement to impart oscillating motion at 1725 revolutions per minute.
Returning to FIG. 1, in some embodiments of the floor treating system 100, a cleaning substance is placed on a floor, the floor treating attachment 130 is placed over the cleaning substance, the cleaning substance is allowed time to dry and crystallize, and the cleaning substance is removed from the floor. The cleaning substance may be any of a number of substances, including, but not limited to, polymer-based cleaning substances, emulsification cleaning substances, and encapsulation cleaning substances. In certain embodiments, the spray system 180 may be utilized to spray the cleaning substance over the floor. In such embodiments, the pump and hose assembly may be used to spray the substance from the spray tank 181 through the spray heads 183 and 184. In some embodiments, the floor treating attachment 130 also provides agitation to the cleaning substance and the floor after the substance is placed on the floor.
An increased distance of the floor treating attachment 130 from the axis of rotation of the rotatable drive shaft, and corresponding increased orbit size and increased speed of oscillating motion, improve efficiency in floor treating. For example, in some embodiments, the floor treating attachment 130 is at least 0.400 inches from the axis of rotation, thereby increasing the agitation provided to the cleaning substance and floor. In such embodiments, the increase in agitation may produce a mixture of moisture, cleaning substance, and soil from the floor, and the mixture may dry, encapsulating the soil. In certain embodiments, the mixture may be easily removed from the floor, for example, with a vacuum. In addition, in providing agitation to a carpet, for example, an increased orbit size of the floor treating attachment 130 is easier on the carpet fibers compared to smaller orbit sizes, thereby preserving the carpet and decreasing the wear on it.
Turning to FIG. 6, multiple embodiments of the floor treating system include a rug beating attachment 600 and means for imparting a vibrating motion from the drive shaft to the rug beating attachment 600, in addition to the floor treating attachment and means for imparting an oscillating motion from the drive shaft to the floor treating attachment. The rug beating attachment 600 may be utilized to beat dirt, dust, and other particles from a rug that is placed over a perforated mat or grate, for example.
Also, in multiple embodiments of the bottom portion 110 (shown in FIGS. 1& 2) of the floor treating system 100, the rug beating attachment 600 takes the place of the floor treating attachment 130. In some embodiments, the means for imparting a vibrating motion from the drive shaft 200 to the rug beating attachment 600 comprise the flywheel 210, the counterbalance 230, and a counterweight 630 configured to attach to the rug beating attachment 600. The counterbalance 230 may connect to the flywheel 210 and the rug beating attachment 600, the counterweight 630 counteracting any reduction in vibrations from the counterbalance 230 and thereby increasing vibrations. In multiple embodiments, the drive shaft 200 of the power source 150 rotates the flywheel 210 around the axis of rotation R, the rotation of the flywheel 210 provides motion to the counterbalance 230, and the counterbalance 230 and the counterweight 630 impart a vibrating motion to the rug beating attachment 600.
In some embodiments, the plug bearing lip 242 extends over part of the rug beating attachment 600 to assist with the connection of the rug beating attachment 600 to the counterbalance 230, while the remainder of the plug bearing 240 is positioned between the rug beating attachment 600 and the counterbalance 230. Any of the plug bearing apertures 280a-280d, or any combination of the plug bearing apertures 280a-280d, may be configured to align with any of the counterbalance apertures 260a and 260b, or any combination of the counterbalance apertures 260a and 260b, each alignment corresponding to a different distance from the axis of rotation R to the rug beating attachment 600. Also, the bolt 270 may extend through any of the plug bearing apertures 280a-280d and any of the counterbalance apertures 260a and 260b to assist with the connection of the rug beating attachment 600 to the counterbalance 230.
In multiple embodiments, the rug beating attachment 600 may be positioned at a distance of at least 0.400 inch from the axis of rotation of the rotatable drive shaft of the power source 150. In some embodiments of the bottom portion 110 (shown in FIGS. 1 & 2), for example, the distance d2 may be approximately 0.4375 inch from the axis of rotation R and the counterweight 220 may have a mass between 1946 grams and 1956 grams. In certain embodiments, the distance d1 may be approximately 0.375 inch and the distance d3 may be approximately 0.5625 inch, with the counterweight 220 having a mass between 1946 grams and 1956 grams.
Each distance from the axis of rotation of the rotatable drive shaft corresponds to a different size of orbit of the rug beating attachment 600. For example, in some embodiments, the rug beating attachment 600 may have a diameter of 15 inches and may be 0.375 inch from the axis of rotation, corresponding to an orbit size of 15.75 inches. In other embodiments, the rug beating attachment 600 may have a diameter of 15 inches and may be 0.4375 inch from the axis of rotation, for example, corresponding to an orbit size is 15.875 inches.
Each orbit size corresponds to a different speed of motion imparted from the drive shaft at a given number of revolutions per minute, and to a different amount of power required to impart that speed of motion. For example, in some embodiments, the rug beating attachment 600 may be 0.25 inch from the axis of rotation of the rotatable drive shaft, corresponding to a 1⁄3 horsepower requirement to impart motion at 1725 revolutions per minute. In other embodiments, the rug beating attachment 600 may be 0.375 inch from the axis of rotation, corresponding to a 0.5 horsepower requirement to impart motion at 1725 revolutions per minute. In other embodiments, the rug beating attachment 600 may be 0.4375 inch from the axis of rotation, corresponding to a 0.75 horsepower requirement to impart motion at 1725 revolutions per minute. In other embodiments, the rug beating attachment 600 may be 0.5 inch from the axis of rotation, corresponding to a 1 horsepower requirement to impart motion at 1725 revolutions per minute.
Additionally, in some embodiments, the rug beating attachment 600 includes a plate 610 and spheres 620-628 configured to attach to the plate 610. The plate 610 may be manufactured from any of a number of materials, including, but not limited to, polymers. The spheres 620-628 may be manufactured from any of a number of materials, including, but not limited to, phenolic resins, and may attach to the plate 610 with bolts, for example.
It will therefore be readily understood by those persons skilled in the art that the embodiments and alternatives of a floor treating system 100 and method are susceptible to a broad utility and application. While the embodiments are described in all currently foreseeable alternatives, there may be other, unforeseeable embodiments and alternatives, as well as variations, modifications and equivalent arrangements that do not depart from the substance or scope of the embodiments. The foregoing disclosure is not intended to be construed to limit the embodiments or otherwise to exclude such other embodiments, adaptations, variations, modifications and equivalent arrangements, the embodiments being limited only by the claims appended hereto and the equivalents thereof.
