Filtered wringer
A wringer for use with wet mops is disclosed. The wringer includes a body having a plurality of side surfaces and at least one perforated section. A filter is disposed adjacent to the perforated section, so that fluid exiting the container through the perforated section will pass through the filter. The filter may be secured to the wringer by slots formed in the wringer body, or with pins, clips or any other similar attaching means. The filter removes dirt and other contaminants from cleansing fluid used with the mop, lengthening the useful lifetime of the cleansing fluid before replacement is needed. The wringer may also have an attachment member to allow the wringer to be used with a bucket or may be formed integrally with a bucket.
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.
BACKGROUND OF THE INVENTIONLabor 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.
SUMMARY OF THE INVENTIONThe 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.
BRIEF DESCRIPTION OF THE DRAWINGS
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. The interior surface 21 of movable section 20 is generally smooth. Internal scaffolding 23 may be used to provide strength to movable section 20 while reducing overall weight. Movable section 20 further comprises arms 24, which project at an angle from the exterior surface of movable section 20 but transverse from rod 22. While two arms 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 connect movable section 20 to actuator 30, which is used to actuate movable section 20 from first position A to second position B.
Actuator 30 further comprises handle 38, rod 34, and arms 36. Actuator 30 is rotatable about axis X, which is co-axial with rod 34. Rod 34 is parallel with rod 22. Arms 36 are fixedly attached to and orthogonally project from rod 34. Arms 36 are pivotably connected to arms 24 of movable section 20 by connecting rod 26 so that an acute angle is formed between arms 24 and arms 36. While connecting rod 26 is used in the preferred embodiment to provide additional structural support to arms 24 and 36, alternative mechanisms for providing connection between arms 24 and 36, such as rivets or bolts, may also be used. Arms 24 and 36 are generally flat and are oriented so that they are aligned along a plane that is orthogonal to axis X. This orientation provides the greatest resistance to bending of arms 24 and 36 due to forces experienced during actuation of movable section 20, while reducing weight and the amount of material needed for arms 24 and 36. Arms 24 and 36 also generally have rounded ends to eliminate sharp corners, helping to prevent injuries to users.
Handle 38 projects orthogonally from rod 34 and provides leverage to allow a user to more easily rotate actuator 30 about axis X. As shown in
Spring 32 is attached to rod 34 and arms 24. Spring 32 biases movable section 20 towards first position A. In a preferred embodiment, spring 32 is attached to rod 34 by inserting rod 34 through the coils of spring 32. It can be readily seen that spring 32 may be connected to movable section 20 and actuator 30 in different configurations. For example, hooks may be used to connect spring 32 to movable section 20 and actuator 30. Another alternative embodiment has spring 32 connecting arms 24 and 36.
As shown in
Perforated section 18 has a plurality of perforations 19 that allow fluid within internal volume 11 to flow out of container 10. Perforations 19 may take on any number of shapes, sizes, and arrangements. In a preferred embodiment, perforated section 18 is disposed on the side wall 14 that is opposite movable section 20, and perforations 19 are shaped as circular holes. In alternative embodiments, as shown in
Filter 40 is attached to the outer surface of perforated section 18 exterior to container 10. Therefore, any fluid that exits container 10 through perforations 19 in perforated section 18 will pass through filter 40. In a preferred embodiment, as illustrated in
Filter 40 may be attached to perforated section 18 by any number of methods. For example, in a preferred embodiment as shown in
As shown in
In use, 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. At the same time, the cleansing fluid is forced through filter 40 after exiting container 10 through perforated section 18. As the cleansing fluid passes through filter 40, dirt and other contaminants and foreign objects are removed from the cleansing fluid after the cleansing fluid passes through perforated section 18, but before it reaches bucket 70. The dirt is thus trapped in filter 40 and kept separate from the cleansing fluid in bucket 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 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.
In another embodiment, illustrated in
The present invention may readily be used with other styles of wringers and wringer/bucket combinations. For example, as shown in
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.
