Description

Detailed Description of the Invention

(Technical field)
The present invention relates to an apparatus for the treatment of surfaces, for example cleaning. More specifically, one embodiment of the present invention is an apparatus for surface cleaning that provides a place to sit or sit for an operator and can be operated even in tight spaces. .

(Background technology)
Cleaning machines are widely used to clean floor surfaces made of tiles, stones, bricks, wood, concrete, carpets and other common surface materials. Maintaining the cleanliness of these surfaces is a continuous and time consuming process, especially in a wide range of commercial, industrial, corporate and public buildings. The present invention relates to a floor cleaning or processing apparatus (hereinafter "processing apparatus") that supports the operator during use and is very easy to operate. More specifically, some embodiments of the invention clean, sweep, vacuum, polish, wax, etc. (hereinafter “treat”) the floored surface. The operator is supported by the cleaning device, thus increasing the efficiency and productivity of the cleaning operation. As used herein, a “floored surface” or, more generally, a “surface” is covered by concrete, tile, carpet, wood, plastic, stone, lawn, or any other material known in the art. It includes the area. Conventional devices address many of the problems that arise with cleaning such floored surfaces. Unfortunately, prior to the present invention, a device that can address many, if not all, of the problems that arise in cleaning various surfaces in various environments at any given time is: There was no one.

A. Mop and bucket cleaning devices In the past, building maintenance personnel, such as tiled entrances, corridors, or floors in hand-washing restrooms, can be used with traditional mop and bucket techniques. Often used to process. The bucket may have a removable mop iron ring and may be placed on a leg ring to assist in easy movement. Depending on the cleanliness of the equipment, the operator may be able to get a good start when treating the floor using the mop and bucket technique. However, soon the fluid in the mop and bucket will become dirty or otherwise contaminated with bacteria and / or bacteria. This problem causes both the mop and the cleaning fluid to become increasingly dirty / contaminated each time an operator pushes the mop into the bucket and squeezes the mop.

B. Hand-held cleaning device The basic cleaning issues associated with prior art mop and bucket systems that address surface cleaning, which are fully incorporated herein by reference, are entitled "multifunctional cleaners". US Pat. No. 6,206,980, issued to Robinson, has been generally focused on in the art. This type of cleaner generally has a hand-wheeled body with two tanks, a coagulation chemical container, a vacuum and blower motor and a fluid pumping system. Typically, such equipment has a single motor that is used to both suck in dirty liquids and blow air that can help dry the cleaned floor. While such equipment is generally easy to operate and improves upon earlier mop and bucket techniques, the system is still labor intensive and slow. As a result, the productivity of cleaning professionals is generally reduced when using these types of systems relative to the productivity of other types of systems available.

C. Self-propelled walk-behind devices Productivity issues have been addressed in the art by creating certain walk-behind floor treatment equipment. These devices typically have a scrub deck at the front of the device and a rubber squeegee at the back of the device. This squeegee has the function of “swinging”, that is, following the path of the scrub deck as the device changes direction. This type of apparatus is generally more efficient than either mops and buckets or hand-held devices when cleaning large surface areas. Unfortunately, however, the distance between the scrub deck and the squeegee is relatively large. The walk-behind type typically has a relatively wide squeegee. These characteristics limit the operability of such devices and limit the doorway through which they can easily pass. A typical 3 foot (3 ') doorway allows a device with a 33 inch (33 ") or smaller squeegee to pass through without removal.

  A small walk-behind floor cleaning device typically has a scrub deck at the middle of the device and a squeegee at the rear of the device. In this configuration, the squeegee has little or no function of swinging, ie following the path of the scrub deck as the device changes direction. Smaller rider scrubbers typically have only a relatively narrow squeegee, adjacent to the scrub deck and directing water to the main (evacuated) squeegee path. Rely on a "side squeegee" (non-evacuated squeegee blade). The problem with these side squeegees is that they don't work very well for long distances, and the evacuated squeegee is the true path of the scrub deck, leaving the water squeegee Since it does not follow only the path, it tends to leave a film of water in sequence. Finally, side squeegees are typically very heavy rubber blades with a significant drop in pressure acting on the blades to direct the water, which makes the side squeegee expensive And create significant “drags” that increase the amount of work on the propulsion unit and limit the battery operating time. Thus, although easier to operate than a large walk-behind floor treatment apparatus, a small apparatus is typically not as clean as a large apparatus.

D. Storage problems in prior art devices Further, the known cleaners do not provide adequate on-board storage for cleaning supplies, cleaning tools, and the like. Likewise, the prior art devices do not give much flexibility to add storage facilities such as scrap when demand arises.

E. Self-propelled boarding devices Self-propelled cleaning devices are also well known in the field and are typically provided in hospitals, department stores, schools, gymnasiums, eg tiled or concrete or carpet floors Adopted to treat wide flooring surface. These devices generally provide the operator with a seat from which the operator can control the operation of the device. These devices are ideal for cleaning large open areas because they can accommodate large amounts of dirty fluids and / or debris without the need for repeated fluid replacement and debris removal. is there. Furthermore, since these devices provide a seat to the user, the user does not get tired early, and the overall productivity of the operator is improved. But unfortunately, these large boarding devices are often used in entrances, corridors, small rooms, or large rooms with many obstacles inside, such as narrower floor surfaces and more confined floor surfaces. It is not particularly suitable for cleaning.

  As is well known in the art, smaller self-propelled cleaning devices exist that are ideal for cleaning smaller rooms and entrances and hallways. However, smaller devices are usually pushed or pulled by an operator. Therefore, a significant drawback of these devices is that they often rely on the operator's strength to maneuver the devices. Even if the device is self-propelled, it often employs a manually operated steering device (steering). After a long shift working time walking behind the processing unit, the operator is completely exhausted, in which case his or her attention will be out of the task at hand, and thus flooring. May result in non-uniform processing on the treated area. Thus, subsequent peers may have to go back and modify some area that was not accurately processed during the initial operating period. Furthermore, if the operator takes time in an area during the extension period, an artificial error related to the length of time the surface is exposed to brushing may occur. Such a situation is not favorable for the floor surface. Devices in the art are also difficult to maneuver and are often not suitable for operation around tight corners (corners), in which case pre- or post-cleaning is performed. Thus increasing the time and cost of the entire operation.

  Thus, providing a device that can be carried by an operator and is suitable for use in small areas and / or tight corners has long been felt at the floor cleaning or processing site. It is. The following disclosure has been improved to ensure optimal floor cleaning or processing with a platform that is adapted for use in narrow areas and adapted to support the operator. Describes floor cleaning and processing equipment.

(Disclosure of the Invention)
It is an aspect of the present invention to provide a floor treatment apparatus that is easy to steer. More specifically, one embodiment of the present invention includes a cradle including an enclosure that houses at least a portion of the internal components of the processing device and a place for installation of the device used during the cleaning operation. (Chassis) part. In addition, one embodiment of the present invention provides a place for an operator to stand, lean or sit. Another embodiment of the present invention comprises a powered steering device that allows very high maneuverability even in areas where there is a tight corner, thereby allowing pre- or post-processing operations. A wider range of flooring surfaces can be treated without the need for In particular, one embodiment of the present invention includes a self-propelled wheel and a simple to use steering device to provide greater maneuverability around obstacles. One embodiment of the present invention uses at least one wheel that provides propulsion and / or steering functions. Yet another embodiment of the present invention uses wheels that are substantially centered under the chassis, so that the entire device does not move substantially in any other direction, 360 degrees, so that it is possible to process the tight corners of the surface. It is another aspect of the present invention to provide a cleaning device that is cost effective to manufacture. Various aspects of the invention are described in more detail.

Chassis One embodiment of the present invention uses a chassis designed to house and protect the internal workings of the apparatus and provide a place for interconnection of auxiliary processing devices used therewith. ing. One embodiment of the present invention uses a chassis constructed of rigid (rigid) plastic, metal, or other common materials used in the art. The chassis of this embodiment also includes a platform for the operator. Alternative embodiments of the present invention employ a foldable, removable or fixed operator seat. Furthermore, a pad or belt can be used to keep the operator safe in the cleaning device and thus in his / her work environment.

  It is still another aspect of the present invention to provide a chassis with a small envelope. In particular, one embodiment of the present invention is small enough to enter and pass through a tight space. Many facilities using the apparatus of the present invention have narrow doorways, narrow passages and narrow elevators. In addition, especially in older buildings that have been refurbished to meet the Americans with Disabilities Act, elevators have minimal capacity and lifting capacity. In order to get inside a small elevator, the chassis has been designed to have a minimal practical envelope and a clear advantage over the prior art. Also, the device of one embodiment of the present invention has components that can be easily removed or adjusted to reduce the profile of the device. Thus, embodiments of the present invention can be used in a variety of structures.

Steering Mechanism Another aspect of the present invention is to provide a cleaning device that is easy to operate and control. In particular, one embodiment of the present invention is equipped with a steering mechanism that allows input from an operator to be efficiently transmitted to the steering wheel of the cleaning device. Instead, for example, joy sticks, touch screens, buttons, remote control elements, etc. can be used to increase the maneuverability of the processing device.

  It is yet another aspect of the present invention to provide a cleaning device that is adapted to efficiently clean an area with a tight corner. In particular, one embodiment of the present invention is adapted to make a 360 degree turn overall without any appreciable lateral movement. This embodiment of the present invention comprises a swivel mechanism generally below the central portion of the chassis, said chassis being adjacent to the swivel mechanism and providing power to rotate the chassis around a centrally located wheel. It has two powered outer wheels to apply. The powered outer wheels can be controlled independently by a joystick, where the motion conveys a directional input to each wheel. One embodiment of the present invention comprises at least one joystick, where forward tilt provides forward motion, backward tilt provides backward motion, and left and right tilt Swivel the device. Instead, two joysticks can be used in a similar manner, where the left joystick tilts backward and the right joystick tilts forward results in a left turn, depending on the placement of the powered wheels , Possibly resulting in a 360 degree left turn.

  Another embodiment of the present invention utilizes steered wheels, handle bars, yokes, or similar devices for steering. The embodiment may have a steering mechanism with power assistance.

  It is another aspect of the present invention to provide a processing device that is powered by a commonly used power plant. In particular, one embodiment of the present invention uses an electric motor to power the device. The electric motor can be powered by a battery, solar energy, or an electrical cord coupled to a fixed power source. In the present invention, power may be supplied by an internal combustion engine instead. As will be appreciated by those skilled in the art, other propulsion means may be used in accordance with the present invention without departing from the scope of the present invention.

Floor Treatment Device One embodiment of the present invention uses a chassis containing a fluid pump assembly and a vacuum assembly. The apparatus further comprises at least two tanks, one for holding a base cleaning fluid, for example water, the second being used It is for holding cleaning liquid and dry waste. The apparatus also includes one or more concentrated cleaning chemical containers designed to hold concentrated chemicals. The container is preferably stored in a lockable structure to increase the overall safety of the device. These agents can be added to the base cleaning fluid immediately prior to application to the surface and when it is desired to facilitate the cleaning of various surfaces.

Tank As mentioned briefly, at least one tank is preferably provided for supplying a liquid that is directed to the flooring surface to be cleaned to facilitate processing. The tank may consist of a duplex compartment in which used water from the surface is stored before disposal. In particular, one embodiment of the present invention uses a tank with a membrane that is movable. In this configuration, clean water and / or cleaning fluid is deposited and agitated on the surface. The dirty water is then drawn up and returned into a portion of the tank, thereby moving the membrane and thus receiving the dirty water. Such an arrangement, which is fully incorporated herein by reference, is disclosed in US Pat. No. 4,759,094. By utilizing a foldable structure, a similar selectively inflatable fluid reservoir region can be created and placed inside the primary fluid tank. This type of arrangement, which is fully incorporated herein by reference, is disclosed in US Pat. No. 4,196,492.

  Of course, clean water can be brought in from an external source, such as a hose, rather than being loaded and stored in the device. However, to enhance the maneuverability and utility of the present invention, it is envisioned that the chassis contains or holds at least one, and possibly multiple fluid tanks.

Cleaning fluid In certain types of processing operations, fluid from a chemical container flows through a tube into a chemical selector having a metering valve. . The selector preferably has a well-defined blocking position in which fluid is prevented from flowing through the selector regardless of the fluid pressure in the fluid line. The selector is responsive to an operator selection input for one of several cleaning chemicals. When a chemical is selected, it flows freely through the chemical selector and the appropriate amount can be fed to one of the various inlets that leads to the mixing tee. The amount of chemical allowed to flow can be adjusted in a known manner by a metering valve built into the selector or separate from the selector. A base cleaning fluid, such as water, can flow from the fluid tank through the separation tube and into the second leg of the mixing tee. The cleaning fluid and the concentrated cleaning chemical mix in the mixing T-tube to create a cleaning fluid. This liquid then enters the pressure pump through the outlet of the selector, where the cleaning liquid can be pressurized and flow into the dispensing device via suitable piping. The pump that draws fluid to and through the selector also preferably has a bypass system to facilitate adjustment of the pump pressure. The use of the pump to draw fluid is preferred because it does not create undesired pressure in the fluid lines and system and generally does not receive gravity feed of fluid.

  The solution is applied to the surface using a dispensing device of any type. In certain preferred embodiments, the dispensing device or associated fluid line or line is equipped with an adjustable valve that regulates the pressure and flow of the fluid allowed to exit the dispensing device. Used. Because of its adjustability, the device can be used as a precleaner for a variety of carpet processes including stain removal or other processes.

  By using the chemical selector, two or more floor treatment chemical containers can be connected to the mixing T-tube for distribution. In operation, the user does not need to add a container, i.e. without having to switch the chemical feed line from one container to another, or can be misplaced, misconnected or easily damaged. Various cleaning agents can be created without having to replace the measuring tip (tip). In this way, the handling process is safer because there is less handling of chemicals. Similarly, the use of a metering valve allows the operator to create a very precise floor treatment agent.

  A one-way check valve is preferably used throughout the apparatus. For example, a check valve is a feed line that supplies cleaning chemicals to a metering T-tube; a line that supplies water to a metering T-tube; a line that supplies cleaning fluid to a pump; a spray gun A line for supplying the cleaning liquid to the pipe; or the measuring T-tube itself may be provided. The check valve prevents back flow of fluid and prevents one fluid from being contaminated with another fluid.

The blower processing apparatus also includes a modular blower assembly. The blower assembly can be operated with the hand away from the entire cleaning device. The blower assembly can be used to dry an area physically remote from where the device is stored. Since the blower assembly is probably separate from the device, it can also be used for other blowing functions, such as blowing leaves, glass, dust or debris, for example. The blower assembly can be used with removable manual nozzles, flexible nozzles, extension rods, etc., thereby increasing the overall flexibility of the blower assembly. The blower assembly can be powered by the power supplied by any typical extension cord, including the power supply of the device, utilizing an integrated on / off switch. The blower can be configured to be stored on the device in one of a variety of convenient ways. It will be appreciated by those skilled in the art that providing this type of modular blower assembly is very beneficial to the overall functionality of the multifunction floor treatment apparatus.

Storage Another aspect of one embodiment of the present invention is that the chassis is preferably within easy reach of the operator, such as bins, trays, bays, and other A storage device. The storage device provides substantial flexibility to the operator when cleaning large buildings or areas with many types of surfaces that require processing. The device also has a modular waste bin / feed bin that can be quickly and easily added to or removed from the device so that the device is configured for one of a variety of floor treatment operations. I have.

Main Pump It is yet another aspect of the present invention to provide a device with a secondary fluid pump that supplies fluid to the main fluid pump prior to starting. In particular, one embodiment of the present invention comprises a secondary or priming pump that is activated prior to activation of the main fluid pump. Prior to activation of the main fluid pump, fluid is introduced into the pump, thereby releasing trapped air that may cause damage to the main fluid pump motor, for example due to vapor lock or cavitation It is often desirable to do so. This priming process is time consuming but can also be done manually, where the user manually adds fluid to the pump or evacuates the pump. Instead and preferably, one embodiment of the present invention comprises a secondary pump that is driven for a short time when the fluid discharge device is initially activated and is confined when the main fluid pump is in operation. Ensuring that there is virtually no air generated.

Squeegee It is another aspect of the present invention to provide a device comprising a squeegee adjacent to a floor treatment device, both generally in the center of the apparatus. The squeegee effectively rocks or follows the path of the floor and does not rely on a non-evacuated side squeegee to direct water to the main evacuated squeegee. Thus, it does not rely on dirty side squeegees, so when the device turns, it is better or improved than is possible with a walk-behind scrubber, and is typical. It provides fluid collection much better than a small rider. One embodiment of the present invention employs a squeegee that rotates about a steering shaft using links supported by rollers and track mechanisms. The absence of a side squeegee means less drag and better use of effective energy. In addition, some embodiments of the invention have adjustable squeegees, skirts or shrouds that have minimal contact with the floor, thus reducing drag and saving battery load. ing. Instead, some embodiments of the present invention include a stop (stop) that contacts the floor without damaging the floor.

In addition, a suction mechanism may be used so that fluid and / or dried particulates are transferred into the container. One embodiment of the present invention has at least one liquid applicator located adjacent to a scrubbing brush and applies the liquid onto the surface after or before scraping by the brush. Application is also envisioned. The waste and the liquid that carries it in suspension are collected by a squeegee and subsequently evacuated into a storage tank or discharged out of the chassis towards an external reservoir. The brush and / or liquid used in this embodiment is suitable for cleaning, cleaning, painting, polishing, sanding, peeling cleaning, varnishing, waxing, etc. can do. It will be appreciated by those skilled in the art that any type of solution suitable for treating any floor surface can be used without departing from the scope of the present invention.

  It is yet another aspect of the present invention to provide a floor treatment apparatus that can be used for various floor maintenance operations. In particular, one embodiment of the present invention is adapted for interconnection to multiple devices to perform various floor treatment tasks. One embodiment of the present invention allows for quick removal of certain processing devices so that different devices can be added thereafter to quickly change the scope of the apparatus, thereby rubbing. It is envisioned to provide a device that is suitable for dropping, carpet cleaning, floor waxing, floor polishing, wax or varnish removal from the floor, vacuuming, and the like. Thus, it is contemplated that the system can be used for multiple cleaning or floor treatment operations.

It is yet another aspect of the present invention to provide a floor treatment apparatus that can have a remote control car washer assembly that is highly mobile. As can be appreciated by those skilled in the art, if so configured, the device can have a car wash wand coupled to a suitable pump and using the device Prior to finish cleaning, it can be used to preclean heavily soiled areas.

  It is yet another aspect of the present invention to provide a floor treatment apparatus that does not require direct contact with an operator to perform its mission. In particular, one embodiment of the present invention is adapted to be remotely controlled. This embodiment of the present invention, all of which is incorporated herein, as taught by US Pat.
