Definitions
- the present invention relates to an apparatus for the treatment, such as cleaning, of a surface. More specifically, one embodiment of the present invention is an apparatus for surface cleaning that provides a standing location for the operator and is capable of operating in tight spaces.
- the present invention relates to a highly maneuverable floor cleaning or treatment apparatus (hereinafter “treatment apparatus”) that supports an operator during use. More specifically, some embodiments of the present invention are adapted to clean, sweep, vacuum, burnish, wax, etc. (hereinafter “treat”) a floored surface, wherein the operator is supported by the cleaning device, thus increasing efficiency and productivity of the cleaning operation.
- treatment apparatus highly maneuverable floor cleaning or treatment apparatus
- some embodiments of the present invention are adapted to clean, sweep, vacuum, burnish, wax, etc. (hereinafter “treat”) a floored surface, wherein the operator is supported by the cleaning device, thus increasing efficiency and productivity of the cleaning operation.
- floored surface or more generally “surface” encompasses areas covered by concrete, tile, carpet, wood, plastic, stone, turf or any other substance known in the art.
- the prior devices address many issues that arise with cleaning such floored surfaces.
- the bucket may include a detachable mop ringer and may be positioned on caster wheels to facilitate easy movement.
- a worker may be able to make a good start in treating a floor using the mop and bucket approach.
- the mop and fluid in the bucket becomes soiled or otherwise contaminated by germs and/or bacteria. From that point on, each time the worker plunges the mop into the bucket and rings the mop, both the mop and cleaning fluid become more and more dirty/contaminated.
- Small walk behind floor cleaning apparatus typically include a scrub deck in the middle of the machine and squeegees at the machine's rear. In this configuration the squeegee has little or no ability to swing or follow the path of the scrub deck as the machine changes direction.
- Small rider scrubbers typically have relatively narrow squeegees, and rely on "side squeegees" (unvacuumized squeegee blades) adjacent to the scrub deck to direct the water into the path of the main (vacuumized) squeegee.
- Self-propelled cleaning devices as e.g. disclosed in US 3,833,691 are generally also well known in the field and are employed to treat large floored surfaces, such as tiled, concrete or carpeted floors found in hospitals, department stores, schools, gyms, etc. These devices generally provide the operator with seating from which he/she can control operation of the device. These devices are ideal for cleaning large, open areas because they are capable of containing large amounts of waste fluids and/or debris without having to repeatedly perform time consuming fluid replacement or debris removal. Moreover, because these devices provide the user with seating, the user does not become prematurely fatigued, increasing overall worker productivity. Unfortunately, these large ride-on machines are not particularly well-suited for cleaning smaller, more confined floor surfaces, which are often found in hallways, small rooms, or even large rooms which have many obstacles therein.

- the operator presence switch 80 of the present invention is designed to act as a safety feature that interrupts the throttle pedal when not depressed. This ensures that the operator has both feet positioned on the platform when the machine is in use. Upon deactivation of the switch, for example if the operator removes a foot from the switch, a neutral mode may be engaged such that no power or forward or rearward motion of the device is possible. In addition, the operator presence switch 80 may ensure that sufficient weight is maintained on the platform at all times as a safety feature.
- the platform switch is in operable connection with the platform, such that it is activated when the operator stands on the platform.
- the operator must then engage a reset device, preferably on the control panel, to initiate motion.
- the purpose of the platform switch and reset switch is to act as a safety feature such that the machine does not immediately move when the operator steps on to the peddle platform.
- a neutral mode may be engaged such that no power and forward or rearward motion is possible.
- the throttle 82 of the present invention is adapted to selectively increase or decrease the speed of the apparatus depending on the desires of the operator. More specifically, various speed ranges may be included: neutral, first, second, third, reverse, etc. (or slow, medium, fast, etc.). In some embodiments, cleaning operations are performed at slow speeds, while transportation from location to location is performed at higher speeds.
- the operator sets the speed range to first, for example, the activation of the throttle 82 will propel the apparatus within that speed range, such that it can not transition from the first range to the second range without a manual shift of the range.
- embodiments of the present invention include a hand speed range selector, wherein the throttle 82 simply turns the desired speed range to an activated mode.
- the neutral mode may also be set by the operator, wherein no amount of throttle 82 engagement will increase the speed of the apparatus.
- the apparatus automatically disengages the throttle.
- a throttle 82 may be provided that provides selective speed increments, such as employed on an automobile, without departing from the scope of the invention.
- Embodiments of the present invention also include a braking mechanism.
- a braking mechanism may be employed such that any motion of the apparatus automatically or gradually ceases.
- the braking mechanism may be electro mechanical, mechanical or hydraulic.
- the foot brake may be provided adjacent to the throttle 82 or operator presence switch 80 that provides the same halting capability.
- hand or emergency brakes may be employed adjacent to the control panel of the apparatus.
- a seat 84 of one embodiment of the present invention is shown. More specifically, embodiments of the present invention include a selectively connectable seating device 84 for engagement with the chassis to increase the operator comfort. Seats 84 of some embodiments of the present invention are selectively adjustable 85, thus making them easy to accommodate any sized individual.
- a receiver hitch, or similar connection mechanism is connected to the rear portion of the platform 4 and a mating device for interconnection to the receiver hitch, or other device, is provided on the seat 84.
- the seat 84 may also include a plurality of hooks, shelves, cup holders, etc. for the securement of cords, bags, or any other type of cleaning or comfort related item.
- the receiver hitch may be used when the seat 84 is engaged or not engaged, for example, to transport other items such as a supplemental wheeled device that may accommodate extra power sources, cleaning supplies, tanks, etc.
- a tank 50 of one embodiment of the present invention is shown.
- Some embodiments of the present invention include a tank 50 that is equipped with a plurality of lights 80 and/or horns that facilitate cleaning and/or act as additional safety features.
- lights may be integrated into bumpers positioned adjacent to the tank 50 or on the sides of the apparatus.
- a filter may be provided in fluid communication with the fluid pump.
- This filter is designed to capture any debris that may adversely affect the operation of the pump.
- the filter is placed in a hard to access location, such that repair or monitoring thereof is very difficult.
- one embodiment of the present invention includes a filter that is situated on the outer surface of the cowling, perhaps on the control panel. Thus, the operator has ample opportunity to monitor the.integrity of the filter and make quick repairs when necessary.
- a vacuum fan 92 which is connected to the front cowling 88 of one embodiment of the present invention is shown. More specifically, a vacuum fan 92 provides suction to remove debris filled fluids from the floor.
- the fan 92 is preferably situated under the control panel 76 of the vehicle, such that the intake cooling air that is drawn in by the vacuum fan 92 is channeled adjacent to the control panel 76 to cool componentry associated therewith.
- the tank 50 may be made out of a formable material such that exhaust channels 94 may be machined or molded into the tank 50.
- the channels 94 direct the exhaust air from the vacuum 92 to an exit muffler of the apparatus.
- the channels 94 also act as a baffle to remove noise energy from the exhaust gases, thus making the entire system more quiet.
- a waste fluid return hose 96 is shown. More specifically, one embodiment of the present invention decreases its profile by inserting the waste water hose 96 into a hose channel 98 that is integrated into the outside surface of the apparatus 2.
- the hose 96 being situated on the outside also has the added advantage of making it very accessible, such that it can be removed and inspected for clogs or breaches.
- some embodiments of the present invention are provided with tip over stops 100 adjacent to the front corners of the apparatus.
- the stops 100 may be replaceable and ensure that the apparatus does not tip over during tight turns.
- the tip over stops 100 are generally constructed out of a material that is harmless to flooring, such as Teflon, silicone, rubber, plastic, etc.
- rollers may be employed that are situated a predetermined distance from the floor to perform the same function.
- the present invention is generally similar to the floor treatment devices used in the art. However, unlike many prior art devices, the present invention provides a location for which the operator can stand thus enabling him or her to more efficiently perform their tasks. In addition, instead of using brute strength to perform the task of steering the cleaning device, a steering mechanism and associated hardware are provided to aid in the smooth transition from one direction to another. Also, the present invention device has a compact profile and mechanism which allows for 360° cleaning of tight spaces.
