FIELD OF THE INVENTION
[0001] 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 or sitting location for the operator
and is capable of operating in tight spaces.
BACKGROUND OF THE INVENTION
[0002] Cleaning machines are used extensively for cleaning flooring surfaces comprised of
tile, stone, brick, wood, concrete, carpets and other common surfaces. Maintaining
the cleanliness of these surfaces, especially in high volume areas in commercial,
industrial, institutional and public buildings is an ongoing and time consuming process.
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. As used herein, "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. Unfortunately, prior to the present invention,
there was no one device that could address many, if not all, of the issues that arise
in cleaning various surfaces in various environments at any given point in time.
A. Mop & Bucket Cleaning Devices
[0003] In the past, building maintenance staff and others often treat surfaces, such as
tiled hallways or restroom floors, using traditional mop and bucket techniques. The
bucket may include a detachable mop ringer and may be positioned on caster wheels
to facilitate easy movement. Depending on the cleanliness of the equipment, a worker
may be able to make a good start in treating a floor using the mop and bucket approach.
However, soon 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.
B. Manually propelled cleaning devices
[0004] The basic cleaning problems associated with the prior art mop & bucket approach to
cleaning a surfaces have generally been addressed in the art, as shown in
U.S. Patent No. 6,206,980 to Robinson, entitled "Multi-functional Cleaning Machine," which is fully incorporated herein
by reference. This type of cleaning machine generally includes a manually propelled
wheeled body with two tanks, one concentrated chemical receptacle, a vacuum and blower
motor and a fluid pumping system. Typically, such equipment includes only a single
motor used for both vacuuming soiled fluid and blowing air that can be used to dry
a cleaned surface. While such equipment is generally maneuverable and is an improvement
over the earlier mop and bucket technology, the system is still labor intensive and
slow. As a result, productivity of cleaning professionals, when using these type of
systems is generally decreased over what it might be with other type of systems that
are available.
C. Self Propelled Walk Behind Device
[0005] Productivity concerns have been addressed in the art by the creation of certain walk
behind floor treatment apparatus. These apparatus typically have a scrub deck at machine's
front and a squeegee at its rear. The squeegee has the ability to "swing" or follow
the path of the scrub deck as the machine changes direction. This type of equipment
is generally more efficient in cleaning large surface areas than either the mop and
bucket or the manually propelled devices. Unfortunately, however, the distance between
the scrub deck and squeegee is relatively great. Also, walkbehinds typically have
relatively wide squeegees. These characteristics limit such machine's maneuverability
and limit the doorways they can easily pass through. Typical 3' doorway allows a machine
with no more than a 33" squeegee to fit through without removal.
[0006] 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.
The problem with these side squeegees is that they do not perform very well for very
long and tend to leave a film of water in turns because the vacuumized squeegee does
not follow the true path of the scrub deck, only the path of the side squeegees (which
leave the film of water). Finally, side squeegee are typically very heavy rubber blades
and have significant down-pressure applied to them to direct the water - this makes
them expensive and causes significant "drag" which increases the work for the propel
unit and limits battery run-time. Thus, while more maneuverable than larger walk behind
floor treatment machines, the small machines typically do not clean as well as the
larger machines.
D. Storage Issues in Prior Art Devices
[0007] Further, known cleaning machines do not provide adequate onboard storage for cleaning
supplies, tools, etc. Likewise, prior art machines do not often provide a flexible
approach to adding storage facilities for trash and the like when the need for such
arises. Machinery that addresses these issues is therefore needed.
E. Self-propelled Ride-on Devices
[0008] Self-propelled cleaning devices 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.
[0009] As is well known in the art, smaller self-propelled cleaning devices are also in
existence that are ideal for cleaning the smaller rooms and hallways. However, smaller
devices are usually pushed or pulled by an operator. Hence, the major drawback of
these devices is that they often rely on operator strength to maneuver the device.
Even if the device is self-propelled, it often employs manual steering. After a long
shift of walking behind a treatment device, the operator is bound to become fatigued,
wherein his or her attention will deviate from the task at hand, thereby possibly
resulting in uneven treatment to the floored area. Thus, a subsequent crew may have
to return and retouch certain areas that were not accurately treated during the first
operation. In addition, human errors related to the amount of time a surface is exposed
to a brush, may occur when the operator lingers over a single area for extended period
of time. This situation is never good for a floor surface. The devices in the art
are also difficult to maneuver and often are not adapted to operate around tight corners,
wherein pre or post cleaning operations must be performed, thus increasing the time
and expense of the entire task.
[0010] Thus, it is a long felt need in the field of floor cleaning or treatment to provide
a device that allows the operator to ride thereon, and which is adapted to be used
in small areas and/or around tight corners. The following disclosure describes an
improved floor cleaning and treatment device that is adapted for use in small areas
that includes a platform adapted to support the operator to ensure optimum floor cleaning
or treatment.
SUMMARY OF THE INVENTION
[0011] It is one aspect of the present invention to provide a floor treatment apparatus
that is easy to maneuver. More specifically, one embodiment of the present invention
is constructed of a chassis section that includes an enclosure that houses at least
a portion of the internal components of the treatment device and a location for installation
of devices that are used during cleaning operations. In addition, one embodiment of
the present invention provides a standing, leaning or sitting location for the operator.
Another embodiment of the present invention is equipped with a powered steering device
that allows for greater maneuverability in areas with tight corners, thereby ensuring
that more of the flooring surface is treated without having to perform pre or post
treatment operations. More specifically, one embodiment of the present invention is
equipped with a self-propelled wheel and an easy to use steering device to provide
increased maneuverability around obstacles. One embodiment of the present invention
employs at least one wheel that provides thrust and/or steering capability. Yet another
embodiment of the present invention employs wheels that are substantially centered
under the chassis such that the entire apparatus is generally capable of 360° rotation
without substantially traversing in any other direction, thus allowing it to treat
tight corners of a surface. It is another aspect of the present invention to provide
a cleaning apparatus that is cost effective to manufacture. Various aspects of the
invention shall now be described in more detail.
Chassis
[0012] One embodiment of the present invention employs a chassis section that is designed
to protect and house the internal workings of the apparatus and provide a location
for interconnection of auxiliary treatment devices used therewith. One embodiment
of the present invention employs a chassis that is constructed of rigid plastic, metal,
or other common materials used in the art. The chassis of this embodiment also is
equipped with a platform for the operator. Alternative embodiments of the present
invention employ a foldable, removable or stationary operator seat. In addition, other
safety features such as pads or belts may be employed to secure the operator into
the cleaning device and thus his/her working environment.
[0013] It is yet another aspect of the present invention to provide a chasis with a small
envelope. More specifically, one embodiment of the present invention is small enough
to fit into and through tight spaces. Often facilities that employ the apparatus of
the present invention include narrow door ways, aisles and elevators. In addition,
especially in older buildings that have been retrofitted to comply with the Americans
with Disabilities Act, elevators are of minimal volume and lining capability. To fit
into small elevators, the chasis is designed to have the smallest practical envelope,
a distinct advantage over the prior art. Also, the apparatus of one embodiment of
the present invention includes components that are easily removable or adjustable
to reduce the profile of the apparatus. Thus, the embodiments of the present invention
may be used in various structures.
Steering Mechanism
[0014] Another aspect of the present invention is to provide a cleaning apparatus that is
easy to operate and maneuver. More specifically, one embodiment of the present invention
is equipped with a steering mechanism that allows for inputs from the operator to
be efficiently communicated to the steering wheels of the cleaning apparatus. Alternatively,
other steering means may be used to facilitate maneuverability of the treatment apparatus,
such as joy sticks, touch screens, buttons, remote control elements, etc.
[0015] It is still yet another aspect of the present invention to provide a cleaning apparatus
that is adapted to efficiently clean areas with tight corners. More specifically,
one embodiment of the present invention is adapted to generally perform 360° turns
without appreciable lateral motion. This embodiment of the present invention is equipped
with a turning mechanism generally under the center of the chassis with two powered
exterior wheels adjacent thereto that provide power to the chassis to pivot around
the centered wheel. The powered exterior wheels may be independently controlled by
joy sticks, wherein movement thereof send directional inputs to each wheel. One embodiment
of the invention is equipped with at least one j oy stick wherein forward deflection
will impart forward motion, rearward deflection will impart rearward motion, and a
side-to-side deflection will cause the apparatus to turn. Alternatively, two joy sticks
may be used in a similar manner, wherein rearward deflection of the left joy stick
and forward deflection of the right joy stick will result in a left turn, and depending
on the placement of the powered wheels, perhaps a 360° left hand turn.
[0016] Another embodiment of the present invention utilizes a steering wheel, handle bars,
a yoke, or similar apparatus for steering. Embodiments may also include a power-assisted
steering mechanism.
Power Plant
[0017] It is another aspect of the present invention to provide a treatment apparatus that
is powered by commonly used power plants. More specifically, one embodiment of the
present invention employs an electric motor to power the apparatus. The electric motor
may be powered by batteries, solar energy or an electrical cord attached to a permanent
power source. Alternatively, the present invention may be powered by an internal combustion
engine. Other propulsion means may also be employed by the present invention without
departing from its scope, as will be appreciated by one skilled in the art.
Floor Treatment Devices
[0018] One embodiment of the present invention employs a chassis that houses a fluid pump
assembly and a vacuum assembly. The apparatus further includes at least two tanks,
one for retaining a base cleaning fluid, such as water, and a second for retaining
spent cleaning solution, dry debris, etc. The apparatus may also include one or more
concentrated cleaning chemical receptacles designed to hold concentrated cleaning
chemicals. The receptacles are preferably stored within a lockable structure, adding
safety to the overall apparatus. These agents can be added to a base cleaning fluid
just prior to application to a surface and as desired to facilitate cleaning of various
surfaces.
Tanks
[0019] As briefly mentioned above, preferably at least one tank is provided that provides
a solution that is directed towards the flooring surface to be cleaned to facilitate
treatment. The tank may be constructed with multiple compartments wherein waste water
from the surface is contained prior to disposal. More specifically, one embodiment
of the present invention employs a tank that includes a movable membrane. In this
configuration, the clean water and/or cleaning solution is deposited on a surface
and agitated. Dirty water is next suctioned up and deposited back into a portion of
the tank, thereby moving a membrane accordingly to accept the dirty water. Such a
configuration is disclosed in
U.S. Patent No. 4,759,094, which is herein incorporated in its entirety by this reference. A similar selectively
expandable fluid storage area can be created by utilizing a collapsible structure,
which is placed inside of the primary fluid tank. This type of arrangement is disclosed
in
U.S. Patent No. 4,196,492, which is also incorporated herein in its entirety by this reference.
[0020] Clean water can obviously come from an outside source such as a hose, rather than
be stored on board the device. However, in order to facilitate maneuverability and
usability of the present invention, it is envisioned that the chassis will house or
hold at least one fluid tank and perhaps a plurality thereof.
Cleaning Solutions
[0021] In one type of treatment operation, fluid from the chemical receptacles flows through
a tube to a chemical selector, which may include a metering valve. The selector preferably
has a positive shut-off position, wherein fluid is prevented from flowing through
the selector regardless of the fluid pressure in a fluid line. The selector is responsive
to input from an operator selection of one of the several cleaning chemicals. Once
a chemical is selected, it is free to flow through the chemical selector and appropriate
amounts thereof may be provided to one of any number of inlets to a mixing tee. The
amount of chemical allowed to flow may be adjusted by a metering valve built into
the selector or separate from the selector, in a known fashion. A base cleaning fluid,
such as water, may flow from a fluid tank and through a separate tube to a second
leg of a mixing tee. The cleaning fluid and concentrated cleaning chemical then mix
within the mixing tee to create a cleaning solution. That solution may then be passed
through the selector outlet to a pressure pump, wherein the cleaning solution may
be pressurized and communicated via appropriate tubing to a dispensing device. The
pump, which draws fluid to and through the selector, also preferably includes a bypass
system to facilitate regulation of pump pressure. Use of the pump to draw fluid is
preferred as it does not create unwanted pressures in the fluid lines and the system,
in general, is not subject to gravity feeding of fluid.
[0022] A solution may be applied to a surface using any type of dispensing device. In a
preferred embodiment, the dispensing device or associated solution lines or tubes
include an adjustable valve, which may be used to adjust the pressure and flow of
solution allowed to exit the dispensing device. Because of the adjustability, the
apparatus may be utilized as a pre-cleaner for various carpet treatments, including
spotting or other treatments.
[0023] By use of the chemical selector, two or more receptacles of floor treatment chemicals
may be fluidly connected to a mixing tee. In operation, a user is capable of creating
any number of cleaning solutions without the need for adding receptacles or switching
chemical feed lines from one receptacle to another or without changing metering tips
that are easily misplaced, incorrectly interconnected, or damaged. Thus, the treatment
process is safer because there is less chemical handling. Similarly, use of a metering
valve will allow the operator to create a very precise floor treatment solution.
[0024] It is preferred that one-way check valves be used throughout the apparatus. For instance,
check valves may be included in: delivery lines that supply cleaning chemicals to
the metering tee; lines that supply water to the metering tee; lines that supply cleaning
solution to the pump; lines that supply cleaning solution to the spray gun; or in
the metering tee, itself. The check valves prevent reversal of fluid and prevent contamination
of one fluid with another.
Blower
[0025] The treatment apparatus also may include a modular blower assembly. The blower assembly
may be hand-held and operate completely apart from the overall cleaning machine. The
blower assembly may be used to dry areas physically separate from where the apparatus
is stored. Because the blower assembly possibly is separate from the apparatus, it
may also be used for other blowing functions, such as blowing leaves, grass, dirt
or other debris. The blower assembly may be used with a detachable hand nozzle, a
flexible nozzle, an extension wand, etc., thereby increasing the overall flexibility
of the blower assembly. The blower assembly may utilize an integrated on/off switch
and be powered by electricity supplied by any typical extension cord, including the
power source of the apparatus. The blower may be configured to be stored on the apparatus
in one of any number of convenient ways. It will be appreciated by one skilled in
the art that having a modular blower assembly of this type is very beneficial to the
overall functionality of a multifunctional floor treatment apparatus.
Storage
[0026] Another aspect of one embodiment of the present invention is that the chassis includes
bins, trays, bays and other storage devices preferably within easy reach of the operator.
The storage devices provide the operator with substantial flexibility when cleaning
a large building or area that has many types of surfaces that may need treatment.
Also, the apparatus provides for modular trash/supply bins that may be added to or
removed from the apparatus quickly and easily so that the machine can be configured
for one of any number of floor treatment activities.
Primary Pump
[0027] It is yet another aspect of the present invention to provide an apparatus equipped
with a secondary fluid pump that supplies fluid to the main fluid pump prior to ignition.
More specifically, one embodiment of the present invention includes a secondary, or
priming pump, which is activated prior to the activation of the main fluid pump. Often
it is desirable to introduce fluid into a main fluid pump prior to that pump's activation,
thereby expelling trapped air that may cause damage to the main fluid pump motor from
vapor lock or cavitation, for example. This priming process may be conducted manually,
but that is time consuming, wherein the user manually adds fluid to the pump or bleeds
the air therefrom. Alternatively, and preferably, one embodiment of the present invention
is equipped with a secondary pump that is activated for a brief moment when the fluid
discharge apparatus is initially activated, thus ensuring that the main fluid pump
will be substantially free of trapped air upon activation.
Squeegee
[0028] It is another aspect of the present invention to provide a device that includes a
squeegee adjacent to the floor treatment device, both generally in the middle of the
machine. The squeegee effectively swings, or follows the path of the floor and does
not rely on unvacuumized side squeegees to channel water to the main vacuumized squeegee.
Thus, it offers as good or better fluid pick-up when the apparatus is turning than
is capable with a walk behind scrubber, and far superior than typical small riders
since it does not rely on smearing side squeegees. One embodiment of the present invention,
employs a squeegee that pivots about the steering axis with a linkage that is supported
by a roller and track mechanism. The absence of side squeegees mean less drag and
better use of available energy. In addition, some embodiments of the present invention
include an adjustable squeegee, a skirt or a shroud that minimally contacts the floor,
thus reducing drag and sparing battery charge. Alternatively, some embodiments of
the present invention include stops that contact the floor, without marring the same.
Use of the Device
[0029] Various aspects of the inventions discussed briefly above combine to provide an effective
and efficient tool, useful in the treatment of numerous areas in and around commercial,
industrial, institutional and public buildings. Moreover, due to the various aspects
of the present invention, a sanitation maintenance worker may clean a particular room
or facility more efficiently than previously possible. The present invention may be
used in various cleaning operations such as burnishing, vacuuming, scrubbing, sanding,
waxing, sweeping, sealing, painting, polishing, etc. In order to accomplish these
tasks, the present invention may be equipped with various combinations of floor treatment
devices. More specifically, one embodiment of the present invention is equipped with
a plurality of brushes and squeegees to agitate and collect debris from a flooring
surface. In addition, suction mechanisms may be employed such that fluids and/or dry
particulate matter are transferred into a container. It is also envisioned that one
embodiment of the present invention include at least one solution applicator positioned
adjacent to the scrub brushes, wherein solution is injected onto the surface after,
or prior to, agitation by the brushes. The debris-entrained solution is then collected
by the squeegee and subsequently vacuumed into the holding tank or expelled out of
the chassis to an outside reservoir. The brushes and/or solution used in this embodiment
may be adapted to clean, sweep, paint, burnish, sand, strip, varnish or wax a floor.
It will be appreciated by one skilled in the art that any type of solution adapted
to treat any flooring surface may be employed without departing from the scope of
the present invention.
[0030] It is yet another aspect of the present invention provide a floor treatment apparatus
that can be used in various floor maintenance operations. More specifically, one embodiment
of the present invention is adapted for interconnection to a plurality of devices
to perform a variety of floor treatment operations. It is envisioned that one embodiment
of the present invention be capable of quick removal of certain treatment devices
such that different devices may be then added to quickly change the scope of the apparatus,
thereby providing a device adapted to scrub, clean carpets, wax floors, burnish floors,
remove wax or varnish from floors, vacuum, etc. Thus, it is contemplated, that this
system may be used for a plurality of cleaning or floor treatment operations.
Remote Control
[0031] It is yet another aspect of the present invention to provide a highly mobile floor
treatment apparatus that can include a car washer assembly. As will be appreciated
by those skilled in the art, if so configured, the device could include a car washer
wand connected to appropriate pumps and could be utilized to pre-clean heavily soiled
areas prior to final cleaning with use of the device.
[0032] It is still another aspect of the present invention to provide a floor treatment
apparatus that does not require direct contact with an operator to perform its tasks.
More specifically, one embodiment of the present invention is adapted to be remote
controlled. This embodiment of the present invention is equipped with remote control
mechanisms and software currently known in the art, such as taught by
U.S. Patent No. 6,625,843 to Kim et al., which is incorporated in its entirety herein. In addition, this embodiment of the
present invention may be equipped with the plurality of cameras such that offsite
monitoring and control may be performed. In a related embodiment of the present invention,
software is installed in the cleaning apparatus such that human contact or monitoring
is not required. More specifically, one embodiment of the present invention is adapted
to learn its environment as it operates in an area such that remote controlling is
not required. Alternatively, it is well within the scope of this invention to preprogram
the dimension of floored surfaces into the smart treatment device, wherein the device
is parameterized with the surface dimensions before the task is initiated. Apparatus
of this type are known in the art, such as the Roomba™ device by iRobot Corporation,
aspects of which are described in
U.S. Patent Nos. 6,594,844 and
6,535,793, which are both incorporated in their entirety herein.
Safety
[0033] It is another aspect of the present invention to provide a cleaning apparatus that
is safe and comfortable to use. More specifically, one embodiment of the present invention
includes an operator platform. This platform allows the operator to stand on the device
during the treatment operation, thus increasing productivity and lowering the chances
of injury or fatigue to the operator. It another embodiment of the present invention,
a seat is provided wherein the operator may comfortably sit while completing his or
her task. Other safety and comfort features such as rails, pads, and belts, may be
provided depending on the needs of the operator.
[0034] Thus, it is one aspect of the present invention to provide a floor treatment apparatus
which comprises:
a chassis with a lower surface, a front surface, an upper surface, a rear surface,
a left surface and a right surface, wherein a platform is provided that is adapted
to support the weight of an operator;
a powered wheel operably connected adjacent the lower surface of the chassis, the
powered wheel being capable of at least one of transitioning and rotating the floor
treating apparatus;
a steering mechanism adjacent to the upper surface that is accessible by the operator;
an operable floor treating device connected adjacent to the lower surface of the chassis;
an operable debris collection device connected adjacent to the lower surface of the
chassis; and
wherein an operator controls the floor treatment apparatus from the platform.
[0035] The Summary of the Invention is neither intended nor should it be construed as being
representative of the full extent and scope of the present invention. Some aspects
of the present invention are set forth in various levels of detail in the Summary
of the Invention, as well as in the attached drawings and the Detailed Description

by either the inclusion or non-inclusion of elements, components, etc. in this Summary
of the Invention.

DETAILED DESCRIPTION
[0039] Referring now to Figs. 1-20 an apparatus 2 for cleaning or otherwise treating a floor
surface is shown. More specifically, one embodiment of the present invention includes
a chassis 8 with a platform 4 that is adapted to support the weight of an operator
6, thus increasing the efficiency of the entire floor treatment operation. In addition,
various cleaning or floor treatment components may be interconnected to the bottom
surface 10 of the chassis, such as brushes 12, scrubbers 14, squeegees 16, vacuum
shoes, etc.
[0040] The chassis 8 also includes a plurality of wheels 18 operably interconnected to the
bottom surface 10 to enable steering and provide stability. It is contemplated that
the operator 6 will stand on the platform 4 and steer the apparatus 2 with either
a steering wheel 20 or other type of steering mechanism, such as a joy stick 22. Such
an embodiment of the present invention enables the floor surface to be cleaned or
otherwise treated more efficiently, since the operator 6 does not have to push or
pull an often heavy apparatus 2. In addition, since the human component of powering
or otherwise moving the apparatus 2 is omitted, more consistent flooring treatment
is achieved, thereby saving materials and reducing costs of the entire operation.
[0041] Referring now to Fig. 1, one embodiment of the present invention is shown. More specifically,
a chassis 8 which includes the platform 4 adapted to support an operator 6 during
the floor treatment operation is shown. The operator 6 preferably stands on the platform
4 that is generally parallel to the flooring surface. Preferably, the platform 4 is
tilted, rear edge higher than the front edge, between about 3 to 8 degrees to increase
ergonomics. However, as it will be appreciated by one skilled in the art, other support
devices, such as seats, which may be operably folded into the chassis 8, may be provided
to increase the comfort level of the operator 6. In addition, the embodiment of the
present invention shown in Fig. 1 is equipped with a steering mechanism, such as a
wheel 18, that allows the operator 6 to easily maneuver the apparatus 2 around the
flooring surface.
[0042] The chassis 8 is constructed of any material, but preferably hard plastic will be
used to reduce the weight of the apparatus 2. As shown herein, a plurality of wheels
18 are operably interconnected to the rear of the apparatus 2 to provide stability
and perhaps power for locomotion. In addition, a squeegee 16 is included that is adapted
to extract or funnel water or debris to a location where it is extracted via vacuum
into a container generally, but not always, located at least partially inside the
chassis 8. Further, this embodiment of the present invention includes a brush 12 that
is used to agitate the flooring surface to loosen dirt, wherein spray nozzles may
be employed situated behind the brush 12 to treat the flooring and capture the dirt
so that it can be gathered by the squeegee 16 and suction system of the apparatus
2.
[0043] Referring now to Fig. 2, an alternate embodiment of the present invention that is
used mainly for fluid extraction is shown. This embodiment of the present invention
is similar to the apparatus described above, however alternate components are interconnected
to the bottom surface 10 of the chassis 8 such that the apparatus is adapted to efficiently
capture fluids or debris deposited on a floored surface. More specifically, this embodiment
of the present invention is equipped with at least one brush 12 adapted to agitate
water and/or debris and a squeegee 16 that is positioned adjacent to the rear surface
of the chassis 8 that contains fluid and debris as the apparatus 2 moves forward.
In one embodiment of the present invention, a suction device, such as a vacuum shoe,
is positioned near the squeegee 16 such that dirty water is vacuumed from the surface
and transferred back into a tank situated inside or adjacent to the chassis 8. Alternatively,
another embodiment of the present invention is provided with a squeegee 16 with a
plurality of suction holes that are the terminus of conduits that transport waste
water to the storage tank.
[0044] In the illustrated embodiment, the operator 6 is able to control the apparatus 2
with a plurality of joy sticks 22. In addition, hand grips 24 are provided on the
sides of the operator 6 to increase safety. Further, this embodiment of the present
invention employs powered wheels 26 that allow the entire system to rotate on a single
vertical axis without substantially transitioning in other directions. More specifically,
this embodiment of the present invention is capable of performing a 360° turn, which
aids cleaning of tight spaces.
[0045] An alternate embodiment of the present invention that is used for burnishing is shown
in Fig. 3. This embodiment of the present invention includes a burnishing pad 28 operably
interconnected to the bottom surface of the chassis 10. As before, the operator 6
stands on a platform 4 built into the chassis 8. One skilled in the art will appreciate
that this embodiment of the present invention may also include a device for suctioning
debris left over from the burnishing process, such as dust or wax particulates, for
example.
[0046] Referring now to Fig. 4, an alternate embodiment of the present invention that employs
swinging brushes 30 is shown. This embodiment of the present invention is very similar
to those described above, however the brushes 30 used to agitate, scrub, or burnish
are rotatably interconnected to the bottom surface 10 of the chassis 8. More specifically,
the brushes 30 of this embodiment are capable of independently folding inwardly, thereby
efficiently cleaning the interior portion of a floor when the apparatus is operating
near a vertical surface such as a wall. As shown herein, the brushes 30 are independently
movable and preferably spring loaded outward such that contact with a vertical surface
causes the brush 30 to fold under the chassis 8. Alternatively, as one in the art
will appreciate, the orientation of the brushes may be controlled by the operator.
In addition, a wand 32 interconnected to a hose 34 may also be employed with this
embodiment of the present invention to allow for selective application of cleaning
solution or suction.
[0047] Referring now to Fig. 5, another embodiment of the present invention that utilizes
centered powered wheels 26 is shown. More specifically, this embodiment of the invention
is similar to those described above, however it is equipped with a plurality of wheels
26 that allow a 360° turning capability. This embodiment of the present invention
is also similarly adapted for cleaning the surface of a floor with a brush 12 or a
plurality thereof that is used to agitate the dirt wherein a squeegee contains and
suctions debris into a container.
[0048] Referring now to Figs. 6-8, an alternate embodiment of the present invention is shown
that is equipped with a wheel 18 with brushes 12 therearound for cleaning in all directions.
This embodiment of the present invention is equipped with brushes 12 that allow for
cleaning or agitation of the flooring surface in any direction the apparatus 2 is
moving, thus efficiently cleaning flooring without having to make multiple passes
over the surface.
[0049] Referring now to Fig. 9, one configuration of cleaning components interconnected
to the bottom surface 10 of the chassis 8 is shown. More specifically, one embodiment
of the present invention is adapted to either sweep or clean a floor. In the illustrated
embodiment, a presweeping brush 12 agitates the carpet or hardwood floor to loosen
debris. Next, rotating scrubbing brushes further agitate the surface and perhaps add
fluid and cleaning solution thereto to help loosen and contain any loose debris. Finally,
a squeegee 16 and preferably a suction system is provided that captures the dirty
water and as the apparatus is moved forward. As shown herein, the drive unit is the
center wheel 26, which is also adapted to selectively rotate upon steering commands
from the operator 6.
[0050] Fig. 9B shows a configuration of cleaning components interconnected to the bottom
surface 10 of the chassis 8 similar to what was shown in Fig. 9A. The difference,
however, is that the pre-sweeping brush 12 has been replaced by three scrub brushes
or three rotating brushes, 13A, 13B and 13C that may be used to either sweep, burnish
or combinations thereof a floor surface. The brushes can rotate at speeds desired
by the operator or at preselected speeds and in directions selected by the operator
or in pre-selected directions.
[0051] Referring now to Fig. 10, an alternate configuration of the cleaning components interconnected
to the bottom surface 10 of the chassis 8 is shown. More specifically, this configuration
is substantially similar to that shown above in Fig. 9, however, the drive mechanism
of the apparatus is a transaxled power plant that provides power to the rear wheels
26, wherein the steering is performed by a front wheel.
[0052] Referring now to Fig. 11, yet another embodiment of the present invention performs
a floor treatment operation without the need of physical human contact is shown. More
specifically, this embodiment of the present invention is remote controlled or otherwise
intelligent such that it cleans a floored surface without the direct contact of an
operator. This embodiment of the present invention may be configured for any task,
such as scrubbing sweeping, vacuuming, burnishing, carpet cleaning, waxing, surfacing,
cleaning, etc. It is envisioned that the operator be in a separate location, perhaps
offsite from the actual cleaning operation, and aided by remote viewing devices. Alternatively,
one embodiment of the present invention is programmed with the ability to automatically
treat a floor surface, wherein the dimensions of the surface are either programmed
into or learned as the apparatus is in use, thereby alleviating any need for human
contact with the apparatus. This embodiment of the present invention may be deployed
from a storage location automatically wherein quick disconnects to fluid sources or
waste receptacles are remotely joined to it such that filling and emptying tanks or
waste containers inside the chassis 8 is done without the need of a human operator
as well. This embodiment of the present invention may be used in areas where it is
dangerous for humans to operate, such as nuclear power plants, areas where asbestos
exposure is likely, etc.
[0053] Referring now to Fig. 12, a squeegee 16 for use in one embodiments of the present
invention is shown. More specifically, some embodiments of the present invention include
a pivot mechanism that allows the squeegee 16 to remain in place when the floor treating
apparatus 2 is turning. Thus, the amount of fluid extracted when the apparatus 2 is
making a tight turn is increased. In the illustrated embodiment, the squeegee 16 is
connected to a swing arm 36 that pivots about a point adjacent to the front wheel
18 of the apparatus. The swing arm 36 is supported via rollers or bearings 38 on a
track 40 that maintain the squeegee's 16 vertical position relative to the floor.
Upon making a right or left hand turn, friction will tend to keep the squeegee 16
in a straight line, following the original path of the vehicle. Once a new line of
travel is established, the squeegee 16 will fall back in place substantially under
the apparatus 2. Fig 12a shows the squeegee 16 in its upmost left position, while
Fig. 12c shows the squeegee in its upmost right position. Fig. 12b shows the squeegee
in a neutral position while Fig. 12d shows the squeegee in a neutral position but
from a side view.
[0054] The squeegee 16 of one embodiment of the present invention is provided with a plurality
of wheels that interface with the floor to maintain the vertical clearance of the
squeegee assembly. In addition, side rollers may be provided that prevent the squeegee
16 from contacting a vertical surface, such as a wall. These wheels and various portions
of the squeegee assembly may be selectively adjustable such that the width of the
squeegee 16 and the placement of the wheels (squeegee height) may be altered at will.
[0055] As shown herein, the swing arm 3 6 connects to a pivot 42 that utilizes the momentum
of the squeegee 16 to swing it from the apparatus 2. However, one skilled in the art
will appreciate other methods of transitioning the squeegee 16 from the floor treatment
apparatus 2 may be utilized without departing from the scope of the invention. More
specifically, a motorized system may be employed that is in communication with the
steering system of the vehicle such that rotation of the steering wheel will swing
the squeegee 16 away from the apparatus 2 in a predetermined manner.
[0056] An actuation system that selectively raises the squeegee 16 from the floor may also
be included as shown in Fig. 12E. In accordance with some embodiments of the present
invention, a handle actuated leverage system 44 is used and is in mechanical communication
with a cam 46. The cam allows the user to apply minimal force to the handle 44 adjacent
to the control panel to raise and lower the squeegee 16. One skilled in the art will
also appreciate that this function may be performed alternatively with a motor.
[0057] Referring now to Fig. 13, a recovery tank strainer basket 48 of one embodiment of
the present invention is shown. Recovery tanks of some embodiments of the present
invention are constructed out of resiliently deflectable material, such as a plastic
bag. The bag is inserted into the clean fluid tank 51 of the apparatus. Once the clean
fluid is transferred to the floor treatment tool of the apparatus, waste water may
be suctioned into the waste fluid tank, thus expanding the bag and occupying the space
once occupied by now dispensed clean fluid. Often, small metal shavings, wood splinters,
glass, etc., may be suctioned with the waste fluid and deposited into the waste fluid
tank, which may produce rips or tears in the bag and ultimately lead to leakage and
contamination of the cleaning fluid. Thus, it is desirable to have a system that captures
any dangerous debris such that it does not come in contact with the waste fluid tank.
One embodiment of the present invention thus includes a strain basket 48 connected
to the cover 49 of the waste fluid tank. In the illustrated embodiment, a generally
rectangular straining device constructed of a rigid material with a plurality of apertures
therethrough is provided. As the waste water is deposited into the tank through the
cover, any large debris is captured by the strain basket 48. One skilled in the art
will appreciate that any sized aperture may be employed to dictate the size of debris
that is captured. Also, it should be specifically understood that any shape of strain
basket 48 may be used without departing from the scope of the invention.
[0058] Referring now specifically to Fig. 13D, a fluid discharge system that is connected
to the waste water tank 58 of one embodiment of the present invention is shown. More
specifically, a fitting 54 with a flange 56 may be used that is connected to the main
storage tank 51 of the apparatus. Preferably, the fitting 54 is spun at a high rate
of speed and engaged with an aperture in the tank 51, thus creating friction induced
heat between the two surfaces and welding them together. The opening of the waste
water bag 58 is then fed through the fitting 54 and a mandrill 60 is added to sandwich
the waste water bag 58 therebetween. The mandrill 60 is made out of a rigid material,
such as aluminum to ensure an open flow path. A drain hose 62 is slid over the outer
surface of the fitting 54 and is secured with a clamp 64.
[0059] One skilled in the art will appreciate that the drain hose 64 is generally capped
during use, wherein the user disconnects the cap to drain the waste water from the
bag 58. To ensure that the bag 58 is entirely empty, a new solution may be added to
the tank, thus squeezing the bag 58 to expel all the waste water contained therein.
[0060] Referring now to Fig. 14, the rear portion of the floor treatment apparatus 2 is
shown. More specifically, the rear of the apparatus 2 includes a removable cowling
66. The cowling 66 of the present invention is capable of selective rotation about
an axis parallel to the rear axle of the apparatus 2. Alternatively, the rear cowling
66 may be completely removable. This aspect of the present invention provides the
ability to access batteries 68 that may provide power to the apparatus 2. The batteries
68 may reside on a removable tray 70 that is slidingly engaged to the apparatus 2,
thus providing easy access for maintenance. The tray 70 resides on tracks that interface
with a plurality of wheels, bearings, etc. The tray also includes a locking feature
that securedly maintains the batteries 68 inside the vehicle. The rear cowling 66
also includes other features, such as a cavity for securing various items and drink
holders 72. A pad 74 may also be included that provides greater protection and comfort
to the user.
[0061] Referring now to Fig. 15, a control panel 76 and associated structure of one embodiment
of the present invention is shown. Embodiments of the present invention include a
control panel 76 that includes minimal fasteners 72 for interconnection to the floor
treatment apparatus 2. That is, thumb screws, or similar type of fasteners may be
included such that quick and easy removal of the control panel 76 may be achieved
to facilitate repair.
[0062] Embodiments of the present invention also include hand grips 24 adjacent to the control
panel 76 to provide support for the operator. More specifically, during tight turns
the inertial forces acting upon an individual may cause an operator to fall. Hand
grips 24, which may be integrated onto the chasis of the apparatus, will give the
operator a place to hold onto the device for added comfort and provide an additional
safety feature. In addition they provide support when operating control switches located
adjacent to handle grip.
[0063] Referring now to Fig. 16, the platform 4 of one embodiment of the present invention
is shown. More specifically, one embodiment of the present invention includes a platform
4 with an operator presence switch 80, a platform switch and a throttle 82. The platform
4 also may include a suspension system and be cushioned to increase operator comfort.
In addition, the platform 4 may be foldable such that the envelop of the apparatus
may be selectively reduced.
[0064] The operator presence switch 80 of one embodiment 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.
[0065] In the typical use, 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. Upon deactivation of the switch, for example if the operator steps from
the apparatus, a neutral mode may be engaged such that no power and forward or rearward
motion is possible.
[0066] The throttle 82 of some embodiments 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. When 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. Thus, 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. In addition, as
mentioned briefly above, when the operator removes his or her foot from the operator
presence switch 80, the apparatus automatically disengages the throttle. One skilled
in the art will appreciate however, that 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.
[0067] Embodiments of the present invention also include a braking mechanism. For example,
when an operator removes his or her foot from the operator presence switch 80, throttle,
or disengages the platform switch, a braking mechanism maybe employed such that any
motion of the apparatus automatically or gradually ceases. The braking mechanism may
be electro mechanical, mechanical or hydraulic. Alternatively, the foot brake may
be provided adjacent to the throttle 82 or operator presence switch 80 that provides
the same halting capability. Further, hand or emergency brakes may be employed adjacent
to the control panel of the apparatus.
[0068] Referring now to Fig. 17, 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. In operation, 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. Further, 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.
[0069] Referring now to Fig. 18, 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. Alternatively, lights maybe integrated into bumpers positioned
adjacent to the tank 50 or on the sides of the apparatus.
[0070] Although not shown, 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. Unfortunately on many cleaning machines, the filter is placed
in a hard to access location, such that repair or monitoring thereof is very difficult.
Thus, 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.
[0071] Referring now to Fig. 19, 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.
[0072] In addition, 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.
[0073] Referring now to Fig. 20, 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.
[0074] Further, 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. In addition, one skilled in the art will
appreciate that rollers may be employed that are situated a predetermined distance
from the floor to perform the same function.
[0075] Referring now to Figs. 1-20, a manner of making the present invention is shown and
described herein. As has been explained, 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 or sit,
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. Further, to construct
the remote control version of the system, software that is known in the art may be
installed in the chassis 8 to allow for the system to be either remotely controlled
or learn the cleaning surface as it operates. In addition, a series of cameras may
be interconnected to the chassis 8 to provide remote viewing to an operator offsite.
[0076] While various embodiment of the present invention have been described in detail,
