Description




BACKGROUND OF THE INVENTION




1. Field of Invention




This invention pertains to a floor-cleaning device. More specifically, this invention pertains to a multi-purpose position sensitive floor-cleaning device having a gravity switch that selectively activates at least a first motor to provide power to at least a first implement when the cleaner is rotated or flipped about its longitudinal axis.




2. Description of the Related Art




It is known in the prior art to provide floor-cleaning devices operated by a switch containing two tubes of mercury, also known as gravity switches. For example, gravity switches have been used to create a “dead man” condition in floor cleaning devices. U.S. Pat. No. 2,138,279 ('279 patent) (expired) discloses such a “dead man” switch. The '279 patent relates to a control switch that includes two tubes of mercury, which are mounted in a head of a floor care appliance. Each tube includes two spaced contacts, which are interposed in an electric circuit. Rotating handgrips that tilt the mercury tubes to complete the circuit operates the machine. A spring is provided to create the “dead man” condition. When the handgrips are released, the spring returns the mercury tubes to the “off” position. Thus, a gravity switch on a floor care appliance for use as a “dead man” switch is known in the art. However, the '279 patent does not disclose the use of a gravity switch to alternate between two or more modes of operation such as scrubbing and suction modes.




It is also known to use a level-sensitive switch to turn off a motor on a carpet-cleaning machine when the handle of the device is tilted. In U.S. Pat. No. 4,146,944 ('944 patent) (expired), a carpet cleaning machine having a handle, a cleaning head with a brush, a brush motor, a solution supply tank, a rinsing reservoir, a waste tank, a vacuum head and a vacuum pump is disclosed. A level sensitive switch is provided in the cleaning head to turn off the brush motor when the handle is tilted to raise the brush and lower the vacuum head. Further, the '944 patent discloses that the same level sensitive switch can be used to turn the vacuum motor on when the handle is tilted. Thus, the level sensitive switch disclosed in this patent selectively activates a first motor, namely, the brush motor, when the handle is tilted to lower the brush and raise the vacuum head. In addition, the gravity switch selectively activates a second motor, namely, the vacuum motor, when the handle is tilted to raise the brush and lower the vacuum head. However, the patent does not disclose rotation of the entire unit to selectively activate a mode of operation.




Another example of use of the use of gravity to influence a device is found in U.S. Pat. No. 3,676,890 ('890 patent) (expired). The '890 patent relates to a suction cleaner having a detent mechanism pivotally mounted by a pin on the handle control lever. The detent includes an arcuate surface at one end; a portion on the other side of the pivot pin is weighted so that it is influenced by gravity to rotate the detent when the cleaner is up-ended onto a surface. The detent engages a roller to lock the cleaner in the upright position and prevent actuation of a switch actuator.




The present invention is an improved multi-purpose position sensitive floor cleaning device having two separate and distinct selective modes of operation whereby 180° rotation of the multi-purpose position sensitive floor cleaning device selectively activates at least one of the two separate and distinct selective modes of operation.




SUMMARY OF THE INVENTION




It is an object of the present invention to provide a multi-purpose position sensitive floor-cleaning device having two separate and distinct selective modes of operation whereby 180° rotation of the floor-cleaning device selectively activates one of the two separate and distinct selective modes of operation. The two separate and distinct selective modes of operation are, for example, a scrubbing mode for scrubbing an associated floor and a suctioning mode for suctioning associated liquid from the associated floor.




The activation of the one of the two separate and distinct selective modes of operation can be accomplished, in its preferred embodiment, by a gravity switch. The gravity switch activates one of the two separate and distinct selective modes of operation due to the gravitational force acting upon the gravity switch.




Another object of the present invention is the multi-purpose position sensitive floor cleaning device to have a longitudinal axis with a cleaning head at a first end of the longitudinal axis and a handle at a second end of the longitudinal axis, a motor being located between the first and second ends for operating the cleaning head, wherein the improvement comprises a switch for activating and deactivating the motor, the switch activates the motor when the floor care device is rotated about the longitudinal axis and when the cleaning head is placed in contact with the floor surface, and the switch deactivating the motor when the floor care device is rotated about the longitudinal axis to place the cleaning head in a non-contact position with the floor surface.




Another object of the improved multi-purpose position sensitive floor cleaning device is to rotate the floor care device 180°, thus placing the cleaning head in a non-contact position with the floor surface.




Another object of the present invention disclosed herein is an improved multi-purpose position sensitive floor-cleaning device for cleaning a bare floor. The improved floor cleaning device has a longitudinal axis, a handle, a housing, the housing having first and second ends, the first end of the housing being attached to the handle, at least two separate and distinct modes of operation, the at least two separate and distinct modes of operation, for example, being a cleaning mode and a suction mode, at least one implement operatively attached to the second end of the housing and having an axis parallel to a plane of a floor, the axis being perpendicular to the longitudinal axis of the improved floor cleaning device, the at least one implement operatively attached to the second end of the housing comprises two implements, the two implements being a power-driven brush and a pump communicating with a nozzle for dispensing a cleaner, the power-driven brush and the pump being located substantially opposite one another, at least one motor operatively connected to the at least one implement, a means for supplying power to the improved floor cleaning device, a means for activating and deactivating the means for supplying power, a means for activating and deactivating the at least one motor, the means for activating and deactivating the means for supplying power being a first switch, the means for activating and deactivating the at least one motor activating the motor by rotating the improved cleaning device 180° about its longitudinal axis such that the at least one implement is in contact with a surface of a floor, the means for activating and deactivating the at least one motor selectively deactivating the at least one motor when the cleaning device is rotated about the longitudinal axis such that the at least one implement is not in contact with the surface of the floor, the means for activating and deactivating the at least one motor being a gravity switch connected to the second motor and, wherein the floor cleaning device is a bare floor cleaning device.




These and other objects of the present invention are achieved by the present invention wherein there is provided a floor cleaning device comprised of a motor housing having first and second ends, a handle attached to the first end of the motor housing, a cleaning housing having first and second ends, wherein the first end of the cleaning housing is attached to the second end of the motor housing, a nozzle attached to the second end of the cleaning housing, a cleaning solution delivery system positioned within the cleaning housing for dispensing unused cleaning solution onto a floor surface and a recovery tank positioned within the cleaning housing for holding dirty cleaning solution. The device further comprises a means for selectively providing power to the suction motor. The means for supplying power is positioned within the motor housing and includes a master switch, a pump, a suction motor for providing power to the pump, a power means for providing an electrical current to the suction motor and a gravity switch operatively connected to the power means and the suction motor. The device further comprises a power driven brush system for selectively providing power to the brush motor. The power driven brush system includes a power driven brush operatively attached to the nozzle and a power driven motor operatively connected to the gravity switch. When the cleaning device is rotated about its longitudinal axis such that the nozzle faces the floor surface, the gravity switch turns off the brush motor and simultaneously turns on the suction motor. In addition, when the cleaning device is rotated about its longitudinal axis such that the power driven brush faces the floor surface, the gravity switch turns off the suction motor and simultaneously turns on the brush motor.




Another object of the present invention is to provide a method of cleaning a floor surface with a floor cleaning device having at least two modes of operation, at least one means for supplying power, at least one means for activating/deactivating the floor cleaning device, the modes of operation being located opposite one another on the floor cleaning device, wherein the method is the steps of placing the floor cleaning device in a first position contacting the floor, rotating the entire cleaning device a first time, the first rotation of the device is preferably a 180° rotation, to activate the means for supplying power to the floor cleaning device, and rotating the cleaning device a second time to deactivate the means for supplying power to the floor cleaning device. An additional step includes the method wherein the floor cleaning device further has first and second implements mounted opposite one another on the floor cleaning device and selectively contact the floor, and wherein the step of rotating the device a first time results in either the first or the second implement contacting the surface of the floor.




Still other benefits and advantages of the invention will become apparent to those skilled in the art to which it pertains upon a reading and understanding of the following detailed specification.

DETAILED DESCRIPTION OF THE INVENTION




Referring now to the drawings wherein the showings are for purposes of illustrating preferred embodiment(s) of the invention only and not for purposes of limiting the same,

FIGS. 1-3

show a preferred embodiment of the invention.

FIGS. 4-6

show a second preferred embodiment of the invention.




With reference to

FIG. 1

, a cleaning device


10


has a first implement


12


, a removable motor housing


14


having first and second ends


16


,


18


, a handle


20


that is connected to the first end of the motor housing


16


and that extends upwardly therefrom, a cleaning housing


22


having first and second ends


24


,


26


, a second implement


28


having a preferred embodiment squeegee


30


connected to the second end


26


of the cleaning housing


22


, and wherein the first implement


12


is mounted approximately opposite the nozzle


28


. In the preferred embodiment, the first implement


12


is shown as a stationary brush (also referenced as


12


) and the second implement


28


is a nozzle (also referenced as


28


). The second end


18


of the motor housing


14


is removably attached to the first end


24


of the cleaning housing


22


to facilitate the emptying and cleaning of a recovery tank


84


, which is located within the cleaning housing


22


, as will be explained in further detail below. In the preferred embodiment, the removable motor housing


14


has a substantially u-shaped configuration and can be assembled/disassembled to the cleaning device


10


by known means in the art.




With continuing reference to

FIG. 1

, in the preferred embodiment, the squeegee


30


facilitates the nozzle


28


in the removal of dirty cleaning solution from the floor surface


34


. However, the nozzle


28


will adequately remove the dirty cleaning solution from the floor surface


34


without the assistance of the squeegee


30


.




With reference to

FIG. 2

, the first end


24


of the cleaning housing


22


contains a cleaning solution delivery system


32


. The delivery system


32


dispenses a cleaning solution


33


onto the floor surface


34


for later scrubbing by a means for scrubbing the associated floor, identified in the preferred embodiment as the stationary brush


12


. The cleaning solution


33


used in the present invention may be any known cleaning solution or combination of solutions, such as water with a detergent additive.




With continuing reference to

FIG. 2

, the cleaning solution delivery system


32


includes a cleaning solution delivery tank


36


having first and second chambers


38


,


40


, a means


51


for releasing the unused cleaning solution


33


and a cleaning solution delivery tube


56


. The first chamber


38


of the delivery tank


36


sits atop the second chamber


40


and a separator wall


42


separates the two chambers


38


,


40


. The first chamber


38


holds the unused cleaning solution


33


and selectively releases it into the second chamber


40


, which in turn releases the solution onto the floor surface


34


via the solution delivery tube


56


, as will be explained in further detail below. The first chamber


38


has an aperture


44


for receiving the unused cleaning solution


33


. The aperture


44


in the first chamber


38


is aligned with an aperture


46


in the cleaning housing


22


and opens thereto to facilitate filling of the first chamber


38


with the unused cleaning solution. The aperture


46


on the cleaning housing


22


is provided with a threaded dispensing cap


48


that can be removed to allow a user to fill the first chamber


38


with solution.




With continuing reference to

FIG. 2

, the means


51


for selective release of unused cleaning solution


33


from the first chamber


38


to the second chamber


40


is accomplished, in the preferred embodiment, by a plunger


52


. The plunger


52


is received within an aperture


50


located on the separator wall


42


. The plunger


52


also abuts the bottom portion


97


of a control rod


95


which is connected at its upper portion


99


to a means for releasing the liquid


54


(shown in

FIG. 1

) positioned on the handle


20


of the cleaning device


10


which controls the dispensing of the unused cleaning solution


33


. The means for releasing liquid


54


selectively moves the control rod


95


to move the plunger


52


from a closed position to an open position and vice versa.

FIG. 2

shows the plunger


52


in its open position.

FIG. 3

shows the plunger


52


in its closed position. With reference to

FIG. 3

, the plunger


52


seals the aperture on the separator wall


42


and prevents the unused cleaning solution


33


from being released into the second chamber


40


. However, engagement of the means for releasing liquid


54


selectively moves the plunger


52


in an upwards direction to its second position, as shown in FIG.


2


. With reference to

FIG. 2

, when the plunger


52


is in its open position, the seal surrounding the aperture


50


on the separator wall


42


is broken which causes a gravitational flow of cleaning solution


33


, as shown by arrows A and B, from the first chamber


38


to the second chamber


40


. This, in turn, causes a gravitational flow of the solution


33


from the second chamber


40


through the solution delivery tube


56


, which is attached to the bottom of the second chamber


40


and extends downward through the nozzle


28


, and onto the floor surface


34


. The gravitational flow of cleaning solution onto the floor surface


34


is stopped by disengaging the means for releasing liquid


54


which returns the plunger


52


to its first position and, thereby, seals the aperture


50


in the separator wall


42


.




In the preferred embodiment, the cleaning solution delivery system


32


is a mechanical system. However, the cleaning solution


33


may also be delivered by an electrically powered delivery system that sprays the cleaning solution onto the floor surface


34


(FIGS.


2


and


3


). Further, any system, which adequately delivers the solution


33


to the floor surface


34


, is within the scope of this invention.




Turning now to

FIG. 3

, the motor housing


14


, which contains the power system


58


that supplies a means for suctioning needed to remove the cleaning solution


33


from the floor surface


34


, is best shown. The power system


58


includes a suction motor


60


, an associated suction motor circuit


76


, a power means


62


, such as batteries


64


which also can be rechargeable, cells or a direct AC power source


66


(as shown in FIG.


7


), a pump


68


, a master switch


70


having first and second positions and a gravity switch


72


, such as a mercury switch


74


(as shown in

FIG. 2

) or a weighted micro-switch


82


. A plurality of wires (not referenced but shown) extend between the suction motor


60


, the power means


62


, the pump


68


, the master switch


70


and the gravity switch


72


and provide the necessary electrical connections therebetween. Masters switch means


70


are well known in the art and therefore will not be disclosed in detail herein. It is sufficient to state that when the master switch


70


is in the first position, power is not supplied to the cleaning device


10


.




With continuing reference to

FIG. 3

, the associated suction motor circuit


76


is controlled by the gravity switch


72


. The gravity switch


72


selectively breaks the associated circuit


76


to turn off the suction motor


60


. When the cleaning device


10


is in the scrubbing mode (as shown in FIG.


2


), suction is not needed. Therefore, when the cleaning device


10


is rotated or flipped about its longitudinal axis


11


such that the stationary brush


12


faces the floor surface


34


, the gravity switch


72


automatically breaks the associated circuit


76


to turn off the suction motor


60


. Turning off the suction motor


60


when the device is in the scrubbing mode is desirable because it conserves power. This is especially important when utilizing the battery


64


for the cleaning device


10


. If the suction motor


60


is left on during the scrubbing mode, the continuous power drain will quickly deplete the batteries


64


and the batteries


64


will be drained before the entire floor surface


34


is cleaned. On the other hand, when the cleaning device is in the suction mode, power is needed to turn on the suction motor


60


, which provides the suction needed to remove the dirty cleaning solution from the floor surface


34


. In sum, when the cleaning device


10


is rotated or flipped about its longitudinal axis


11


such that the nozzle


28


faces the floor surface


34


, the gravity switch


72


automatically closes the associated circuit


76


to turn on the suction motor


60


.




In operation, a user activates the cleaning device


10


by moving the master switch


70


from a deactivated position to an activated position. Then, the user rotates the cleaning device


10


about its longitudinal axis


11


such that the stationary brush


12


faces the floor surface


34


. Next, the user engages the means for releasing liquid


54


on the handle to dispense the unused cleaning solution onto the floor surface


34


and the user manually scrubs the floor surface


34


with the stationary brush


12


. After the floor surface


34


is scrubbed, the user rotates the cleaning device


10


about its longitudinal axis


11


, in the preferred embodiment 180° such that the nozzle


28


faces the floor surface


34


. This causes the gravity switch


72


to close the associated suction motor circuit


76


, which turns on the suction motor


60


. The user can then suction the dirty cleaning solution upward through the nozzle


28


as shown by arrows C and D, along the direction of arrows E and F and into the second end


26


of the cleaning housing


22


. A solution reflecting plate


80


can be located in the cleaning housing


22


to deflect the dirty cleaning solution downward in the direction of arrow G and into the recovery tank


84


. The user can repeat this process as many times as is needed until the floor surface


34


is adequately cleaned. Once the floor surface


34


is clean or when the recovery tank


84


is fall, the user can remove cleaning housing


22


from the motor housing


14


to empty and clean the recovery tank


84


.




Turning to

FIGS. 4-6

, a cleaning device having a power driven brush


78


is illustrated by way of example. Except for the power driven brush system


92


, this cleaning device


90


has the same overall configuration as the cleaning device


10


described in the first embodiment of this invention. Therefore, the description for the cleaning device


10


having the stationary brush


12


is included herein by reference and only the power driven brush system


92


will be described in detail.




With reference to

FIG. 6

, the power driven brush system


92


includes a power driven brush


78


, a brush motor


86


and an associated brush motor circuit


88


. A plurality of wires extend between the power driven brush


78


, the brush motor


86


, the power supply


62


and the gravity switch


72


and provide the necessary electrical connections therebetween. In the preferred embodiment, the wires removably connect the brush motor


86


to the gravity switch


72


and the power means


62


so that the cleaning housing


22


can be removed from the motor housing


14


to facilitate emptying and cleaning of the recovery tank


84


. However, the recovery tank


84


may be provided with a cleaning solution removal means (not shown), such as an aperture in the recovery tank (not shown), to allow the tank


84


to be emptied without having to remove the cleaning housing


22


from the motor housing


14


. Such a configuration would enable the brush motor


86


to be hard wired to the gravity switch


72


and the power means


62


.




With specific reference to

FIG. 6

, the gravity switch


72


selectively transfers power from the suction motor


60


to the brush motor


86


. When the cleaning device


90


is in the scrubbing mode, power must be supplied to the power driven brush


78


to facilitate scrubbing of the floor surface


34


. Therefore, when the cleaning device


90


is rotated or flipped about its longitudinal axis


11


such that the power driven brush


78


faces the floor surface


34


, the gravity switch


72


automatically breaks the associated suction motor circuit


76


to turn off the suction motor


60


and simultaneously closes the associated brush circuit


88


to turn on the brush motor


86


. On the other hand, when the cleaning device is in the suction mode, power is needed to turn on the suction motor


60


, which provides the suction needed to remove the dirty cleaning solution from the floor surface


34


. Therefore, when the cleaning device


90


is rotated or flipped about is longitudinal axis


11


such that the nozzle


28


faces the floor surface


34


, the gravity switch


72


automatically breaks the associated brush motor circuit


88


to turn off the brush motor


86


and simultaneously closes the associated suction motor circuit


76


to turn on the suction motor


60


.




In operation, a user activates the cleaning device


90


by moving the master switch


70


from the first position to the second position. Then, the user rotates or flips the cleaning device


90


about its longitudinal axis


11


such that the power driven brush


78


faces the floor surface


34


, which turns on the brush motor


86


. Next, the user engages the means for releasing liquid


54


on the handle


20


to dispense the unused cleaning solution on the floor surface


34


and the user uses the power driven brush


78


to scrub the floor surface. After the floor surface is scrubbed, the user rotates or flips the cleaning device


90


about its longitudinal axis


11


such that the nozzle


28


faces the floor surface


34


. This causes the gravity switch


72


to turn off the brush motor


86


and to simultaneously turn on the suction motor


60


. The user can then use the nozzle


28


to suction the dirty cleaning solution off the floor surface


34


and into the recovery tank


84


. The user can repeat this process as many times as is needed until the floor


34


surface is adequately cleaned. Once the floor surface


34


is clean, the user can remove cleaning housing


22


from the motor housing


14


to empty and clean the recovery tank


84


.




In the preferred embodiment, separate motors drive the power driven brush


78


and the pump


68


. However, a single motor (not shown) can power both the power driven brush


78


and the pump


68


. In this configuration, the gravity switch


72


would selectively transfer power from the single motor to either the power driven brush


78


or the pump


68


.




The invention has been described with reference to two preferred embodiments. Obviously, modifications and alterations will occur to others upon a reading and understanding of this specification.
