- Movable section 20 is movable from a first position A to a second position B (see FIGS. 3A and 3B , further described below), which reduces the size of internal volume 11 .
- Sealing members 24 on edges 22 of movable section 20 minimize the leakage of fluid from container 10 where movable section 20 meets side walls 14 . However, even if some fluid is able to leak out of container 10 through edges 22 , this does not seriously hamper the effectiveness of the present invention.
- the components of container 10 are made of plastic, although other materials, such as metal, may also be used.
- Movable section 20 is generally rectangular and is attached to container 10 at its base by means of rod 22 , about which movable section 20 is pivotable.

- filter 40 comprises a plurality of coarse fibers 42 bonded together to form a non-woven mat 44 . Fibers 42 may be aligned or randomly formed and fiber mat 44 may also be bonded to a second layer 46 , which may comprise a nylon scrim. The construction of filter 40 allows fluid to pass through filter 40 while trapping dirt and other particles within fibers 42 . Fibers 42 may be composed of polyester, polyolefin, acrylic, polyamide, aramid, felt or other similar durable and inexpensive material.
- the filter may also be formed of natural fibers, or a combination of natural and synthetic fibers.
- the porosity of filter may be selected to capture a variety of particle sizes (e.g., 100 to 400 microns) and different types/sizes of filters may be employed in different applications to target particles in a particular size range.
- the porosity for filter 40 should be selected so that the filter traps dirt and other waste particles typically encountered in cleaning floors while remaining sufficiently porous to allow fluid to easily pass through filter 40 .
- Filter 40 may be attached to perforated section 18 by any number of methods.
- filter 40 is attached to perforated section 18 by a plurality of rails 48 projecting from the inner surface of perforated section 18 .

- Projections 62 and 64 are configured to extend substantially down the side of bucket 70 , but are not actively clamped or attached to bucket 70 . This allows wringer 1 to be adequately secured to bucket 70 during normal use while allowing wringer 1 to be quickly and easily removed simply by lifting wringer 1 away from bucket 70 .
- Wringer 1 is oriented upon bucket 70 so that fluid that flows through perforated section 18 will be deposited into bucket 70 .
- Bucket 70 may also have wheels 74 , allowing the user to roll bucket 70 along the ground instead of having to carry bucket 70 from one location to the next.
- Wringer 1 is also oriented in relation to bucket 70 so that when the user presses against handle 38 with force F, force F is directed towards the center of bucket 70 . This prevents an unbalancing of wringer 1 and bucket 70 that might cause the wringer 1 and bucket 70 to fall over.
- the wringer and bucket may be of a unibody construction.
- a mop head is inserted into container 10 through open top 12 .
- the user presses against handle 26 , rotating actuator 30 to actuate movable section 20 from first position A towards second position B.
- This action squeezes the mop head between movable section 20 and perforated section 18 , wringing dirty cleansing fluid from the mop head.
- the cleansing fluid is forced through filter 40 after exiting container 10 through perforated section 18 .
- the cleansing fluid used may include water, a commercial cleansing solvent, and/or some other type of suitable fluid.
- filter 40 within container 10 of wringer 1 is advantageous in several respects. Filter 40 is clearly visible to the user at all times. This allow for quick recognition of when filter 40 needs replacement after too much dirt has been trapped in filter 40 . Filter 40 is also easily accessible for replacement or cleaning, either when filter 40 is dirty, or when a different type of filter 40 is required when a different cleansing fluid is being used. Also, the position of filter 40 within container 10 allows for the positive forcing of the cleansing fluid through filter 40 , instead of relying upon gravity or other passive means for filtering the cleansing fluid. This increases the speed of the filtering process, thus further reducing the total time required during mopping.
- perforated section 118 may be disposed on movable section 120 of wringer 100 .
- filter 140 is attached to the exterior surface of movable section 120 .
- this embodiment utilizes an actuator 130 that is not located in a manner that would impede the flow of fluid through perforated section 118 .
- the force that actuates movable section 120 should not unbalance wringer 100 or the container to which it is attached.
- a second preferred embodiment utilizes actuator 130 that comprises handle 138 attached to first gear 132 , which is rotatably attached to wringer 100 .
- first gear 132 are interlocked with the teeth of second gear 134 , is fixedly attached to movable section 120 and is coaxial with rod 122 . Pressing upon handle 138 causes the rotation of first gear 132 , which in turn causes the rotation of second gear 134 in the opposite direction, resulting in the pivoting of movable section 120 about rod 122 towards side wall 114 .
- First gear 132 and second gear 134 may be dimensioned to provide the optimal mechanical advantage for user to actuate movable section 120 through the movement of handle 138 .

Abstract
Description
- The present invention relates to wringing devices for use in the floor-maintenance industry. More particularly, the present invention relates to a mop wringer having a filter for prolonging the useful life of a floor care fluid used with mops during floor maintenance, while also reducing the labor associated with such floor maintenance.
- Labor is the largest expense item in cleaning. Innovations which minimize the amount of time required to complete cleaning activities reduce overall costs associated with such necessary maintenance.
- In the prior art, a mop is often used with a bucket/wringer combination. The bucket is filled with a cleansing fluid, which is usually a mixture of water and detergent. The mop is inserted into the bucket to rinse it and/or to absorb the cleansing fluid. The wringer is used to remove excess fluid from the mop before it is used to clean a floor or other surface. The fluid from the wringer is returned to the bucket, allowing it to be reused. However, dirt and other contaminants that are picked by the mop during mopping accumulate within the bucket. Within a relatively short period of time, the cleansing fluid can become too dirty to continue to be used effectively, and will need to be replaced.
- In a mopping activity, the amount of time required to complete a task is prolonged because of the need to frequently replace the cleansing fluid used with the mop. Reducing the number of times that the cleaning fluid needs to be replaced can lead to significant savings in both time and cost.
- Therefore, there is a need for a device that will allow for the reclamation of cleansing fluid from a mop that has been used while simultaneously removing dirt particles, waste particles and other contaminants from the cleansing fluid, thus prolonging the useful life of the cleansing fluid.
- The present invention described herein solves the problem of removing dirt particles and other contaminants from the cleansing fluid used with mops by providing a wringer with a filter that filters dirt particles and other contaminants from the cleansing fluid that is wrung from the mop by the wringer.
- In a preferred embodiment of the present invention as described herein, a wringer comprises an open top and a plurality of side surfaces, with the plurality of side surfaces forming an internal volume. The wringer further comprises a first wringing surface that is movable between a first position and a second position, a second wringing surface having at least one perforation, and a filter that is disposed on the second wringing surface. The internal volume of the wringer body is decreased as the first wringing surface is moved from the first position to the second position, and the filter is configured and adapted to prevent dirt particles or other waste particles from flowing through the at least one perforation during wringing.
- In a second preferred embodiment, a wringer comprises a wringer body having an open top and a plurality of side surfaces, with the plurality of side surfaces forming an internal volume, a first wringing surface movable between a first position and a second position and having at least one perforation, and a filter that is disposed on the first wringing surface. The internal volume of the wringer body is decreased as the first wringing surface is moved from the first position to the second position, and the filter is configured and adapted to prevent dirt particles from flowing through the at least one perforation during wringing.
- In a third preferred embodiment, a wringer comprises a compartment having a variable internal volume, a perforated section forming a portion of the compartment, and a filter disposed within the compartment. Fluid within the compartment passes through the filter before flowing through the perforated section.
- In a fourth preferred embodiment, a wringer comprises a container having an open top and an internal volume, a movable part that is movable between a first position and a second position, a perforated section with an internal surface, and a filter. The internal volume of the container is decreased as the movable part is moved between the first position and the second position, and the filter is attached to the internal surface of the perforated section.

FIGS. 1-4 illustrate a first preferred embodiment of the present invention as described herewith.Wringer 1 generally comprisescontainer 10,actuator 30,filter 40, andattachment member 60.Container 10 hasopen top 12, a plurality ofside walls 14,movable section 20, and perforatedsection 18, which define aninternal volume 11.Movable section 20 is movable from a first position A to a second position B (seeFIGS. 3A and 3B , further described below), which reduces the size ofinternal volume 11.Sealing members 24 onedges 22 ofmovable section 20 minimize the leakage of fluid fromcontainer 10 wheremovable section 20 meetsside walls 14. However, even if some fluid is able to leak out ofcontainer 10 throughedges 22, this does not seriously hamper the effectiveness of the present invention. In a preferred embodiment, the components ofcontainer 10 are made of plastic, although other materials, such as metal, may also be used. -
Movable section 20 is generally rectangular and is attached tocontainer 10 at its base by means ofrod 22, about whichmovable section 20 is pivotable. Theinterior surface 21 ofmovable section 20 is generally smooth.Internal scaffolding 23 may be used to provide strength tomovable section 20 while reducing overall weight.Movable section 20 further comprisesarms 24, which project at an angle from the exterior surface ofmovable section 20 but transverse fromrod 22. While twoarms 24 are used in this preferred embodiment, it is noted that one arm or three or more arms may also be used without departing from the spirit and scope of the invention.Arms 24 connectmovable section 20 toactuator 30, which is used to actuatemovable section 20 from first position A to second position B. -
Actuator 30 further comprises handle 38,rod 34, andarms 36.Actuator 30 is rotatable about axis X, which is co-axial withrod 34.Rod 34 is parallel withrod 22.Arms 36 are fixedly attached to and orthogonally project fromrod 34.Arms 36 are pivotably connected toarms 24 ofmovable section 20 by connectingrod 26 so that an acute angle is formed betweenarms 24 andarms 36. While connectingrod 26 is used in the preferred embodiment to provide additional structural support toarms arms Arms arms movable section 20, while reducing weight and the amount of material needed forarms Arms - Handle 38 projects orthogonally from
rod 34 and provides leverage to allow a user to more easily rotateactuator 30 about axis X. As shown inFIGS. 1-2 , handle 38 is generally angled upwards, allowing a user to grasp and press againsthandle 38 without having to bend down. The minimization of bending reduces the potential for user injury.Handle 38 may also be provided with acrosspiece 39, allowing the user to grip the top ofhandle 38 in a horizontal manner.Crosspiece 39 may be covered by a gripping material to further aid in grippinghandle 38. In a preferred embodiment, handle 38 androd 34 are formed from a single piece of bent metal tubing, but may also be formed of any other suitable material, e.g., molded plastic. However, handle 38 androd 34 may be formed as two separate parts and subsequently connected together. -
Spring 32 is attached torod 34 andarms 24.Spring 32 biasesmovable section 20 towards first position A. In a preferred embodiment,spring 32 is attached torod 34 by insertingrod 34 through the coils ofspring 32. It can be readily seen thatspring 32 may be connected tomovable section 20 andactuator 30 in different configurations. For example, hooks may be used to connectspring 32 tomovable section 20 andactuator 30. Another alternative embodiment hasspring 32 connectingarms - As shown in
FIGS. 3A and 3B , pressing onhandle 38 with force F causesarms 36 to pivot about axis X. This exerts a translational and rotational force onarms 24 through connectingrod 26.Arms 24 respond to this force by pivoting about connectingrod 26 so that the angle betweenarms 24 andarms 36 increases while exerting a pushing force uponmovable section 20. Movement ofhandle 38 is thus translated into pivotal movement ofmovable section 20 aboutrod 22 towards second position B. Asmovable section 20 moves towards second position B,internal volume 11 ofcontainer 12 is reduced, andmovable section 20 is brought closer toperforated section 18. When handle is released, the bias exerted byspring 32 returnsmovable section 20 andactuator 30 back to first position A. -
Perforated section 18 has a plurality ofperforations 19 that allow fluid withininternal volume 11 to flow out ofcontainer 10.Perforations 19 may take on any number of shapes, sizes, and arrangements. In a preferred embodiment,perforated section 18 is disposed on theside wall 14 that is oppositemovable section 20, andperforations 19 are shaped as circular holes. In alternative embodiments, as shown inFIGS. 7A and 7B ,perforations 19 are shaped as slots with rounded ends, and arranged either vertically or horizontally. Furthermore,perforated section 18 may be disposed on other parts ofcontainer 12. -
Filter 40 is attached to the outer surface ofperforated section 18 exterior tocontainer 10. Therefore, any fluid that exitscontainer 10 throughperforations 19 inperforated section 18 will pass throughfilter 40. In a preferred embodiment, as illustrated inFIG. 8 , filter 40 comprises a plurality ofcoarse fibers 42 bonded together to form anon-woven mat 44.Fibers 42 may be aligned or randomly formed andfiber mat 44 may also be bonded to a second layer 46, which may comprise a nylon scrim. The construction offilter 40 allows fluid to pass throughfilter 40 while trapping dirt and other particles withinfibers 42.Fibers 42 may be composed of polyester, polyolefin, acrylic, polyamide, aramid, felt or other similar durable and inexpensive material. The filter may also be formed of natural fibers, or a combination of natural and synthetic fibers. The porosity of filter may be selected to capture a variety of particle sizes (e.g., 100 to 400 microns) and different types/sizes of filters may be employed in different applications to target particles in a particular size range. As one skilled in the art will readily appreciate, the porosity forfilter 40 should be selected so that the filter traps dirt and other waste particles typically encountered in cleaning floors while remaining sufficiently porous to allow fluid to easily pass throughfilter 40. -
Filter 40 may be attached toperforated section 18 by any number of methods. For example, in a preferred embodiment as shown inFIGS. 9A and 9B ,filter 40 is attached toperforated section 18 by a plurality ofrails 48 projecting from the inner surface ofperforated section 18.Rails 48 are formed on three sides offilter 40, allowingfilter 40 to be slid in and out ofrails 48.Rails 48 are configured to form a slot into which filter 40 may be removably inserted. This allows a user to easily remove and re-insertfilter 40 whenfilter 40 requires cleaning or replacement. Alternatively, as shown inFIG. 2 , filter 40 may be attached tosection 18 by a plurality of pins orbuttons 41. In still another embodiment shown inFIGS. 13A and 13B , filter 40 may be attached using a plurality ofclips 164. - As shown in
FIG. 4 ,attachment member 60 allowswringer 1 to be attached tobucket 70. In the preferred embodiment illustrated,attachment member 60 consists ofprojections wringer 1 to be placed over and seated uponlip 72 ofbucket 70.Projections bucket 70, but are not actively clamped or attached tobucket 70. This allows wringer 1 to be adequately secured tobucket 70 during normal use while allowing wringer 1 to be quickly and easily removed simply by liftingwringer 1 away frombucket 70.Wringer 1 is oriented uponbucket 70 so that fluid that flows throughperforated section 18 will be deposited intobucket 70.Bucket 70 may also havewheels 74, allowing the user to rollbucket 70 along the ground instead of having to carrybucket 70 from one location to the next.Wringer 1 is also oriented in relation tobucket 70 so that when the user presses againsthandle 38 with force F, force F is directed towards the center ofbucket 70. This prevents an unbalancing ofwringer 1 andbucket 70 that might cause thewringer 1 andbucket 70 to fall over. In an alternate embodiment, the wringer and bucket may be of a unibody construction. - In use, a mop head is inserted into
container 10 through open top 12. The user presses againsthandle 26, rotatingactuator 30 to actuatemovable section 20 from first position A towards second position B. This action squeezes the mop head betweenmovable section 20 andperforated section 18, wringing dirty cleansing fluid from the mop head. At the same time, the cleansing fluid is forced throughfilter 40 after exitingcontainer 10 throughperforated section 18. As the cleansing fluid passes throughfilter 40, dirt and other contaminants and foreign objects are removed from the cleansing fluid after the cleansing fluid passes throughperforated section 18, but before it reachesbucket 70. The dirt is thus trapped infilter 40 and kept separate from the cleansing fluid inbucket 70. The cleansing fluid used may include water, a commercial cleansing solvent, and/or some other type of suitable fluid. - The placement of
filter 40 withincontainer 10 ofwringer 1 is advantageous in several respects.Filter 40 is clearly visible to the user at all times. This allow for quick recognition of whenfilter 40 needs replacement after too much dirt has been trapped infilter 40.Filter 40 is also easily accessible for replacement or cleaning, either whenfilter 40 is dirty, or when a different type offilter 40 is required when a different cleansing fluid is being used. Also, the position offilter 40 withincontainer 10 allows for the positive forcing of the cleansing fluid throughfilter 40, instead of relying upon gravity or other passive means for filtering the cleansing fluid. This increases the speed of the filtering process, thus further reducing the total time required during mopping. - In another embodiment, illustrated in
FIG. 5 ,perforated section 118 may be disposed onmovable section 120 ofwringer 100. In this embodiment,filter 140 is attached to the exterior surface ofmovable section 120. Preferably, this embodiment utilizes anactuator 130 that is not located in a manner that would impede the flow of fluid throughperforated section 118. Furthermore, the force that actuatesmovable section 120 should not unbalancewringer 100 or the container to which it is attached. As shown inFIGS. 6A and 6B , a second preferred embodiment utilizesactuator 130 that comprises handle 138 attached tofirst gear 132, which is rotatably attached towringer 100. The teeth offirst gear 132 are interlocked with the teeth ofsecond gear 134, is fixedly attached tomovable section 120 and is coaxial withrod 122. Pressing uponhandle 138 causes the rotation offirst gear 132, which in turn causes the rotation ofsecond gear 134 in the opposite direction, resulting in the pivoting ofmovable section 120 aboutrod 122 towardsside wall 114.First gear 132 andsecond gear 134 may be dimensioned to provide the optimal mechanical advantage for user to actuatemovable section 120 through the movement ofhandle 138. - The present invention may readily be used with other styles of wringers and wringer/bucket combinations. For example, as shown in
FIGS. 10A and 10B afilter 40 may be installed on anindustrial type wringer 150 having no moving parts or metal components. As shown inFIG. 10B , filter 40 may be formed in a conical configuration to fitwringer 150. In an alternate preferred embodiment shown inFIGS. 11A and 11B , filter 40 may be installed on adownpress type wringer 160. As shown inFIGS. 12A and 12B , filter 40 may be attached towringer 160 with a series of push pins 162 that mate with corresponding apertures on both sides ofwringer 160. Alternatively, as shown inFIGS. 13A and 13B , a plurality ofclips 164 may be used to securefilter 40 towringer 160. In addition, as shown inFIGS. 9A and 9B , slots may be formed integrally with the wringer body to holdfilter 40 in place. As another example, an electrical motor could be incorporated into the wringer to assist in squeezing a mop inserted into a compressor volume. As one of ordinary skill in the art can readily appreciate, for each of the wringer types disclosed herein, the wringer may be formed integrally with a bucket as a single unit. - The present invention may also be used in other apparatus for use in floor maintenance. For example, filter 40 may be used with an apparatus used for the waxing of floors.
Filter 40 would be configured to have an appropriate porosity and would be composed of suitable materials for the fluid being used. - It can be readily seen by those skilled in the art that a wringer in accordance with the present invention may take many different configurations in addition to the ones presented here while remaining within the spirit and scope of the present invention. For example, the wringer may have more than one movable section, and the motion of the movable section may be different than the one herein described. Furthermore, other actuating mechanisms other than the actuator disclosed herein may also be used. Accordingly, it should be clearly understood that the embodiments of the invention described above are not intended as limitations on the scope of the invention, which is defined only by the following claims.
