Abstract
An apparatus is provided including a motor, a belt that rotates in response to the motor, an extension arm, and a scrub head attached to the extension arm. The scrub head oscillates back in forth in response to rotation of the belt. The scrub head is adapted to allow the attachment of one or more cleaning pads. The cleaning pads may be doodlebug pads. A method is provided comprising causing a belt to rotate in response to a motor; and causing a scrub head attached to an extension arm to oscillate back and forth in response to rotation of the belt.
Description
- This invention relates to improved methods and apparatus for stripping, cleaning, scrubbing or sanding floor surfaces and their adjacent edges.
- Typically in the prior art floor surfaces are sanded or stripped by machines, which rotate circular abrasive pads, brushes or sandpaper. However, in certain applications parts of the floor close to a wall are typically stripped by hand using what is known as a doodlebug pad. These pads are typically square or rectangular and are attached to a long pole that is maneuvered in a back and forth motion by a person using the doodlebug pad. This is very labor intensive, taking a long time to accomplish and often the results are only marginal in quality at best. Others will use steel wool to do the edges or even a grill cleaning pad. So a need exists to automate the process of doodlebugging on various floor surfaces. Also in the area of floor care the baseboards tend to be ignored because there is no real way to do them, except manually by hand. This is very intensive and requires much labor. There is a need to do it quicker and cheaper.
- Also in tile cleaning with grout, i.e. bathrooms, commercial kitchens etc., cleaning of these areas is done by a brush and solely by manual labor. This is an arduous and poor quality process. While there are some grout cleaning machines, none address the need of the edges of grout tile laid floors or their adjoining baseboard areas.
- Typically in the prior art, wood floor edges are the worst part of the job. Current machines still have about ⅛ to ¼ of the edge unsanded. Also the wood baseboards are often destroyed and /or need replacement.
- The present invention automates the process of stripping, cleaning or refinishing the parts of a floor nearest walls or edges. Unlike prior art machines, the present invention provides an apparatus and method, which allows doodlebugging of all edges and their adjoining ninety degree perpendicular surfaces, as well as full extension to allow complete exposure of all open ended displays. An apparatus in accordance with an embodiment of the present invention, may include an extension arm, which may have at least two optional lengths to give at least two different reaches. An apparatus in accordance with the present invention gets to absolute edges. In one embodiment, an apparatus is provided including a four head attachment comprised of first, second, third, and fourth heads. The first head may be used for tile edges or any other edge surface. The second head may be used on edges as well as baseboards. The third head may be used to clean grout laid tile. The third head may clean the grout as well as the ceramic tile. The fourth head may be used to sand wood floors. In one embodiment of the present invention, a twenty-four volt battery may power the apparatus, which is particularly applicable to the floor care industry. In another embodiment, the apparatus may be powered by 110 volt alternating current from a standard electrical outlet, which may be particularly applicable to the rental industry, or hospitals. The apparatus may have adjustable ergonomic handles for comfort. The entire head assembly may use double sealed ball bearings.
- The apparatus in embodiment includes crank bearings mounted inside a swivel bearing. This arrangement results in a low profile head assembly. The apparatus may also include an extension arm, which in conjunction with a low profile head may allow the apparatus to reach under equipment for cleaning. The apparatus may include a shuttle block, which has threaded inserts for allowing easy attachment of a scrubbing pad holder and optional attachments. The apparatus may include shuttle bearings which ride within hardened steel rails and a hardened steel top plate, which provide a robust mechanism and a long life. The apparatus may include a handle with slotted holes, which allows for easy adjustment for operators of different heights.
- An apparatus in one embodiment is provided comprising a motor, a belt that rotates in response to the motor, an extension arm, and a scrub head attached to the extension arm. The scrub head oscillates back in forth in response to rotation of the belt. The scrub head may be adapted to allow the attachment of one or more cleaning pads, which may be doodlebug pads. A method is provided comprising the steps of causing a belt to rotate in response to a motor, and causing a scrub head attached to an extension arm to oscillate back and forth in response to rotation of the belt.
