Description
208~267 BACKGROUND OF THE INVENTION
The mops of which I have knowledge of fall into two categories:
1. The traditional mop which is a head made of either lengthy strands of woven cloth or lengthy wide strips of absorbent cloth.
The mops of which I have knowledge of fall into two categories:
1. The traditional mop which is a head made of either lengthy strands of woven cloth or lengthy wide strips of absorbent cloth.
2. The sponge mop which has a head made of a piece of stiffer, porous material ~no strands or strips~.
1. TRADITION MOP METHOD
Mop head must be dipped into pail of cleaning solution and water to absorb water and solution. The excess water and -----solution must be wrung out through pressing or twisting mop- -into pail top wringer. This action must be repeated until floor - -has been washed. -2. SPONGE MOP METHOD ~ -Same method as above (#1) except that the excess water and cleaning solution must be squeezed through moving the action ~--arm on the stick thus causing the sponge to expel water or, as in another type of sponge mop, through pressing the manual metal sqùeezer directly over the sponge head. ;-_ . , .. , ., .. , . . ., ., _ , . .. , _ , _ _ . _ _ .
"~
""," , ,, ~ , 208~2~7 Both of the above methods require making constant trips back and forth from the pail to the floor, saturating the mop and then releasing cleaning solution onto the floor. Each time the mop must be resaturated by placing it back into the pail of water thus mixing dirty solution from the floorwith what was originally clean solution from the pail - this being ~he most common method employed by people. As more area is cleaned, the being the most common method employed by people. As more area is cleaned the solution gets dirtier and the floor is subsequently mopped with the same. By having to lift and shove the pail of solution around while cleaning there is the possibility of spilling the cleaning solution accidentally onto thefloor or onto nearby carpet. Because the solution gets dirty rapidly the additional changing of solution in the pail may be necessary if one desires a relatively clean floor. Because the head of either mop becomes heavy when saturated with water, it makes the task of maneuvering the mop on and off the floor in order to resaturate it cumbersome.
One embodiment of the invention will now be described in conjunction with the accompanying drawings in which:

DETAILE~ DE~ÇRIPTION
My device is illustrated in the accompanying drawings and explained here. This device has the distinct feature of being a closed system, having a clean solution reservoir and a built-in solution recycling, cleaning and filtering mechanism. (Model A) This device has a frame A consisting of a long handle and a housing head B which houses the mophead C and its components.
Mounted on the frame is a clean solution reservoir D. This eliminates the need for a pail. The initial cleaning solution is poured into the reservoir using a rubber tube E which acts as a funnel which can be pulled out and placed onto a sink tap and then placed back. Because of its extension hose, the device does not have to be lifted off the floor during filling.
The mop normally becomes sufficiently saturated throughout the course of cleaning the floor surfaces by the process described hereinafter. Additional saturation, it needed, or to initially wet the mop fibers (that are in contact with the floor area) can be acquired by the pull of a button F on the handgrip G by one use of the rod H. The rod 11, as it is pulled, opens a small outlet I located inside the reservoir ~ that leads into the mophead, thus allowing solution by gravity flow to enter in and then disperse direct to floor area through holes in mophead fibers in contact with the flo~r. An air inlet J into the reservoir aids in gravity flow of salution. A
, . , , ,,~ . ,, ., ... ,, ,,,, ,, ~ . . , 208~267 return spring K along the rod resets the button F to a closed position when Iet go. Saturation will then be automatic.
The cylindrical mop L itself is fitted and fixed onto a cylinder (N) which has holes through its structure to allow passage of solution through it from within and then out, allowing the cleaning solution to flow into the mop fibers especially for the purpose of flushing out mop fibers.
The cylinder has end caps M which are bridged together by the ~, mophead outlet T as one piece. A large gearw5 is fixed onto one end of cylinder(N?so that it can be turned. The mop L is installed onto the cylinder.
The cylinder has holes throughout its solid structure to allow passage of solution through it from within to the outside to flush out the mop fibers from the inside out.
The cylinder with the mop fibers fixed to it, slides over the bridge piece T to rotate upon it. Each end cap has spacers M2 on its rim to reduce friction of the cylinder rotating around it as well as allow air passage.The end caps also have air holes.
Each end cap has mounting bars M3 which are snapped into place in sockets M4 of the frame head B. They are suspending the bridged piece into a fixed position so that cylinder and mop can rotate around it.
The mophead is held into a fixed position during the first phase of cleanin~ the floor. The mop in this fixed position can clean the floor area and mop the floor as do other types of mops concerning this particular type of actian with one part of the periphery of the cylinder(Nl being in contact with the floor surface, , ~ ." i',!~
` ^ 5 208~2~7 With the bottom part of my mop then becoming dirty from the area just passed over, there is no need to go to a pail to rinse and wring OUt the mop. Rather, the dirty solution is merely flushed out of the mop fibers and the mop is wrung out by a simple action, without having to remove the mop from the floor.
This particular type of action is effected upon the device with the use of leverage power using gears, a rod and a turbine type pump system. The action of flushing out dirty mop fibers begins by pressing direct injection pump lever 0 thus leveraging a set of gears from within the handgrip G. The hand lever has at its short end a gear rack 01 which is approximately one inch in length that spins a large dual gear 2 by its centre gear 3. This dual gear is used to increase the rotations of a gear 4 placed at a 90 angle and attached to the long rod and spun by those of the outer of the dual gear. A ratchet 5 and a gear is attached to ~he dual gear so that gears don't reverse when lever is reset by a return spring 6. A latchet lock Q against gear teeth keeps the gears from moving while the lev0r is in a released position and only releases when lever is squeezed.
The long rod H extends down the frame into the pump apparatus R located at the base of the reservoir. The pump is shown in cross-section in Figure 5 and comprises a cylindrical case R1 positioned off-centre within accompanying non rotating circular three-sided chamber R2 including a cylindrical wall, flat ceiling and floor. The whole of the pumping mechanism consist of two pumps in n~dé~ A~ - an upper R3 for pumping solution out of reservoir into the mophead C and a lower R4 for pumping up returning solution back into reservoir ~or re-use. The core has a blade R5 (the blade in Figure 5 m~ves counter-clockwise) ,, :, ` ~ 6 208~2~
used to push liquid etc. which is positioned within the slide R6 located in and running across the core's centre that allows passage and movement of the blade, in or out, from either side of the core to the other. The blade is twice as long as the core itself thus allowing the length necessary for the blade to come out the other side of the core at an exact amount that is being pressed inward from the opposite side. The blade, as it is spun by the core, is pressed in completely and extended out to the other side as it follows and glides against the curvature of the chamber wall R2 beginning at the fullest extension point of the forward circuit spin of the blade this half of wall running to core is not oval shape at point(Ra)as displayed in diagram R which pushes the blade inward in each rotation. Liquid enters the chamber's enclosed area through inlet R7 in the upper pump where the blade simultaneously begins to extend outward from being completely tucked into core located at point ~b pushing liquid forward through an outlet R9 in the upper pump section and R10 in the lower pump section which is to inject returning solution into reservoir by -point ~ b- narrowest to the core and chamber wall where it must exit because of the total decrease of space between wall and cbre.
The chamber wall ~?ast pOint ~b is rounded to approximately 118 to 1/4 inch width at its widest point giving this half of the chamber wall a slightly oval shape that tapers to normal at point ~a allowing the blade as it extends away from the core in forward motion the necessary space required to move uncramped because of the off-centered position of the core within the chamber. The blade, being as wide as the ceiling floor and wall of the chamber area, moves solution as well as sucking in solution ~ ; " , " - ~
2~8~26~
behind it thus filling the chamber as the blade is pushing liquid forward to the pump outlet.
The solution exiting the upper section of the pump follows into a channel S leading into the mophead and reaching the main outlet T
approximately 1/2 inches wide and full length of inner mophead and fitted snug against the inner perforated cylinder wall. As the solution continues, it passes through the cylinder walls and fiber openings flushing out dirty solution from the mop fibers from the inside out onto surface of mophead dislodging dirty solution mopped up from the floor resulting in cleaned fibers.
The solution build-up occurring from flushing out mop fibers is contained by a dam cover U extending along the full length of mophead and approximately 3 inches wide and is constructed as part of the frame which has one lip at the bottom just below the wringer pole V and one at the top edge along the full length of the dam cover and enclosing the sides as well, pressing against mop fibers so that the dam cover channels the solution caused by pump flow and build-up of solution) ~o the centre area of mophead and frame into a collecting area where the lower seçtion of the pump R4 is located and spinning thus moving the dirty solution onwards through a filter V1 removable by a sliding tray for chan0ing and back into the -reservoir for re-use.
Riding ori the same spin action of the rod H, gear and leverage system is the turning apparatus which rotates the mophead consisting of an end bevel gear W located at the lower end of the pump's core that spins a bevel gear W2 that is att~ched to a drive rod W3 having a gear W4 at the opposite ~ , ",~ ~,,, ,," ~ "-,", ,,,,", - "~
,,, . i,, ~ ,.
,j~.", 8 208~2~7 end. This end gear W4 has its teeth engaged with those of a large gear W5 which is mold as or part of cyl~nder N of the mophead thus rotating the mophead (approximately 113 of a rotation) while the mop fibers are being flushed out from the inside.
A blade X with.c~nb ~eeth to prevent dirt from passing along the mophead rotates is part of frame placed within the cover dam U positioned directly in front & aboveagainst wringer pole which is firmly embedded into the mop fibers, pressing them flat against the cylinder wall and thereby wringing out excess solution from the mop as fibers pass beneath.
A brush Z with end gears ;Z2 and Z3 spins off the movement of the large gear W5 ` helps to remove dirt or debris. Bristles on the brush are curved and on an angle away from but come into contact with mop fibers, which as the fibers pile facing opposite way of the brush bristles on an angle, come into contact with brush bristles to comb the fibers and lessen the chance of fibers becoming entangled in brush.
Because this water is filtered and recycled, only a fraction of the water used with the conventional method of a water pail is needed as a reserve ~about 1 1/2 liters or less). This avoids wasting large amounts of water and cleaning solution. Because relatively little water is released on the floor during the mopping process itself much will be reabsorbed by the mophead. A lot of floor area can be covered before it is totally used up.
Only a small amount is lost each time as it continues to be recycled.
The device is drained and the wringer pole relaxed to avoid drying indentations in the mop fiber material by pulling a small lever AA near hand0rip to release the pumps through which pressure needed to wring out ,~ 9 2~8~267 mop fibers is applied. The pump housing R is generally held in place by snap clips.
A drain door situated at one end of the wringer pole handle is pulled back at the same time and opened the drain channel CC thus allowing the mophead's outlet and its channel feed to drain into the dam cover U collecting area and into return pump R4.
As the return pump R4 is pulled back by the above mentioned action, a short gear rack acts to turn the filter to face in the opposite direction ~ of solution flow, thereby positioning the filter to be reversed flushed With the drain open, flow from upper pump is redirected into return pump R4 and into the reversed positioned filter flushing it from a simple squeeze of the hand lever o resulting in a cleaned fil~er. As the solution is not flowing through the mophead outlet during the above action, and wringer pole being relaxed makes the task of reverse flushing somewhat easier on the hand squeeze action of the handle 0. The filter will be reset when pumps are pushed forward in the next cleaning action.
Next the drain door is opened, the device is tilted and the remaining solution discarded. Squeezing the hand lever O while device is tilted upward will empty the pumps R3,R4 of drainage from outlet and channels S to allow proper drying and airing out of the device.
The filter tray is removable from the outside of the device from the return channel as it simply slides in or out.
If desired, a flap extending along the full length and width of inner reservoir can be used to separate unused portion of solution from ~" ,," " , ~ , j, .. . . . . . . .
^ lo 2~8~2~7 returning solution. The flap is inserted by the drain lid and is centered into asocket on the pump body R to pivot the flap against a full length frame lip one side edge of flap and on other lip (opposite side) to butt against the opposite side edge of flap thereby holding the flap into position when the opposite end is slid into a notch to hold the flap positioned.
The device can be left without being drained in between short cleaning intervals or periodical cleaning occurrences or until all solution becomes used up. Liquid wax can be used in the device to wax floors. The device can be used to clean walls, etc.
With the above technique, using the new device, mopping and cleaning floors can be achieved without any of the above mentioned annoying encumbrances, difficulties or other specified existing drawbacks.
These awkward procedures have now been overcome. Now at the mere push of a button, the mop is additionaliy saturated and at the mere pull of the hand lever the mophead is rotated, wrung out and cleaned and the solution is filtered, and mop fibres are automatically saturated.
A sponge made of rubber foam (approximately one quarter inch thick) with nylon hairs on the surface for maximum ease of gliding may be used or a fiber cloth made up of strands with a rubber base having perforations in it for passage of solution can be used. Fibers can be relatively short because there is no need to heavily saturate the mop to convey solution around. Either one will be made as replaceable refills.
(See page 14 and acccmpanyi~g Figure 6 for model B).
2~8~6~
MODEL B
Model B is identical in principle to that of model A. One pump, identical in function as in Figure 5 is used as opposed to two pumps. tsee Figure 6) The single (R) pump, pumps both the fresh solution being taken in from reservoir to mophead (C) and the returning soiled solution through the filter (VI) and pumping the solution directly back into mophead (instead of reservoir) for re-use.
Fresh water from reservoir and liquid detergent (from a separate molded container within the main reservoir) mix together in an appropriate amount at inlet (R14) near the pump's solution return inlet (R15) as is needed due to solution usage during cleaning process.
The addition of fresh solution occurs when air enters the pump from the Dam Cover (U) area (due to the decrease of fluid circulating) and is able to enter the air-tight reserv~ir through an air inlet (R16) from the pump thus allowing the --vacuum suction within reservoir to release liquid to pump according to the amount of air that has entered the reservoir thereby keeping the level of fluid circulating to mophead adequately constant. As pump is kept full of liquid, air cannot enter air inlet to reservoir thereby refraininq any unneeded liquid from entering pump or any additional inlet to (S) channel used.
The button (F) on Model ~ when pressed open allows air into a small channel (B17) (constructed as part of the frame (A) leading down directly to mophead's hollow interior to release liquid entering the small channels at the base of the reservoir into mophead for additional saturation of fibres when needed.
The remaining water from main reservoir can be discarded through a lid, which can be placed in this model (B) just below the pump when pump is pulled back without discarding any of the remaining liquid cleaning detergent thus avoiding wastage and minimizing the amount of environmentally hazardous chemicals from going down the drain. (A horizontal floating flap attached to rod H can be used to keep solution from swishing around from movement of unit).
, Claims All claims for model B are the same as the claims in model A except for the adjustrnents being made to read as one pump being used instead of two in claim no. 6,7,15, and 16 and as solutions being directed directly back to mophead instead of reservoir in claims no. 6, 8, 15 and 16.

A drain door situated at one end of the wringer pole handle is pulled back at the same time and opened the drain channel CC thus allowing the mophead's outlet and its channel feed to drain into the dam cover U collecting area and into return pump R4.
As the return pump R4 is pulled back by the above mentioned action, a short gear rack acts to turn the filter to face in the opposite direction ~ of solution flow, thereby positioning the filter to be reversed flushed With the drain open, flow from upper pump is redirected into return pump R4 and into the reversed positioned filter flushing it from a simple squeeze of the hand lever o resulting in a cleaned fil~er. As the solution is not flowing through the mophead outlet during the above action, and wringer pole being relaxed makes the task of reverse flushing somewhat easier on the hand squeeze action of the handle 0. The filter will be reset when pumps are pushed forward in the next cleaning action.
Next the drain door is opened, the device is tilted and the remaining solution discarded. Squeezing the hand lever O while device is tilted upward will empty the pumps R3,R4 of drainage from outlet and channels S to allow proper drying and airing out of the device.
The filter tray is removable from the outside of the device from the return channel as it simply slides in or out.
If desired, a flap extending along the full length and width of inner reservoir can be used to separate unused portion of solution from ~" ,," " , ~ , j, .. . . . . . . .
^ lo 2~8~2~7 returning solution. The flap is inserted by the drain lid and is centered into asocket on the pump body R to pivot the flap against a full length frame lip one side edge of flap and on other lip (opposite side) to butt against the opposite side edge of flap thereby holding the flap into position when the opposite end is slid into a notch to hold the flap positioned.
The device can be left without being drained in between short cleaning intervals or periodical cleaning occurrences or until all solution becomes used up. Liquid wax can be used in the device to wax floors. The device can be used to clean walls, etc.
With the above technique, using the new device, mopping and cleaning floors can be achieved without any of the above mentioned annoying encumbrances, difficulties or other specified existing drawbacks.
These awkward procedures have now been overcome. Now at the mere push of a button, the mop is additionaliy saturated and at the mere pull of the hand lever the mophead is rotated, wrung out and cleaned and the solution is filtered, and mop fibres are automatically saturated.
A sponge made of rubber foam (approximately one quarter inch thick) with nylon hairs on the surface for maximum ease of gliding may be used or a fiber cloth made up of strands with a rubber base having perforations in it for passage of solution can be used. Fibers can be relatively short because there is no need to heavily saturate the mop to convey solution around. Either one will be made as replaceable refills.

MODEL B
Model B is identical in principle to that of model A. One pump, identical in function as in Figure 5 is used as opposed to two pumps. tsee Figure 6) The single (R) pump, pumps both the fresh solution being taken in from reservoir to mophead (C) and the returning soiled solution through the filter (VI) and pumping the solution directly back into mophead (instead of reservoir) for re-use.
Fresh water from reservoir and liquid detergent (from a separate molded container within the main reservoir) mix together in an appropriate amount at inlet (R14) near the pump's solution return inlet (R15) as is needed due to solution usage during cleaning process.
The addition of fresh solution occurs when air enters the pump from the Dam Cover (U) area (due to the decrease of fluid circulating) and is able to enter the air-tight reserv~ir through an air inlet (R16) from the pump thus allowing the --vacuum suction within reservoir to release liquid to pump according to the amount of air that has entered the reservoir thereby keeping the level of fluid circulating to mophead adequately constant. As pump is kept full of liquid, air cannot enter air inlet to reservoir thereby refraininq any unneeded liquid from entering pump or any additional inlet to (S) channel used.
The button (F) on Model ~ when pressed open allows air into a small channel (B17) (constructed as part of the frame (A) leading down directly to mophead's hollow interior to release liquid entering the small channels at the base of the reservoir into mophead for additional saturation of fibres when needed.
The remaining water from main reservoir can be discarded through a lid, which can be placed in this model (B) just below the pump when pump is pulled back without discarding any of the remaining liquid cleaning detergent thus avoiding wastage and minimizing the amount of environmentally hazardous chemicals from going down the drain. (A horizontal floating flap attached to rod H can be used to keep solution from swishing around from movement of unit).
, Claims All claims for model B are the same as the claims in model A except for the adjustrnents being made to read as one pump being used instead of two in claim no. 6,7,15, and 16 and as solutions being directed directly back to mophead instead of reservoir in claims no. 6, 8, 15 and 16.
