Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to mops. More particularly, the invention relates to a wet mop having a self-contained wringer and unique wringing element which is incorporated on the mop or may be retrofit to a conventional wet mop.




2. Related Art




There exist numerous types of mops in the art, such as twist mops, squeeze mops, wringer mops, etc. Each of these mops will include a handle, mop head material connected to the handle and means for removing water from the mop head material upon demand.




A problem associated with prior mop designs is the way in which to they wring the absorbed liquid from the mop head material connected to the mop handle. In the case of self wringing type mops, there lacks a sufficient means for wringing the mop head material in a manner to permit effective removal of the absorbed liquid while minimizing damage to the mop head material.




Most mechanical wringers fail to adequately provide a way to control the amount of water remains in the mop head. This is because these mechanical wringers are designed to make a single pass across the mop head wringing from the top down and restricting the mop head material into a predetermined amount of space. This is not found to be desirable since it reduces the life of the mop head material and does not provide for any selectivity in the amount of water to be drained from the material. There is a desire to provide a mop wringer which can control the amount of water is squeezed from the mop head and do so in a less deleterious manner.




Another problem with existing mops is that they do not adequately displace the wringer from the mop head to maximize the use of the mop head material. For example, the mop head material of the self wringing mop is connected to a head having a wringer plate hinged thereto. The wringer plate is pivoted in a manner to squeeze the mop head material. This type of wringer is less desirable as it prevents circumferential access to the mop head material.




Other wringing mechanisms, attached and detached from the mop, twist the mop head material in order to remove the liquid therefrom. This is less desirable as it tends to weaken and wear the material.




Other problems associated with conventional mops is that they have a relatively small footprint for mopping, use only a portion of the yarn/mop head material and is easily tangled. These mops and their current wringing mechanisms are relatively expensive to produce.




There remains a need therefore to provide an improved mop, particularly, a mop having a self-contained wringer with improved wringability and positionability of the mop head material. There is also a need to provide a self-contained wringer which retrofitable to a conventional wet mop, such as a deck mop.




SUMMARY OF THE INVENTION




It is an object of the present invention to improve mops.




It is another object of the present invention to improve self-contained wringing mops.




It is a further object to improve the wringability of a mop with a self-contained wringer.




It is an object to improve the control amount of water in which mop head material can be removed through a wringer.




It is another object to provide a rubber-glove like wringer to substantially avoid water contact with one's hands.




Accordingly, the present invention is directed to a mop having a self-contained wringer which includes a handle, a sleeve frictionally movably disposed on the handle such that the sleeve is self supporting along a number of positions of the mop handle, a retainer member connected to an end of the handle and having, a retaining surface, a mop head material having one end connected to the retaining surface of the retainer member, a twistable rubber-like generally fluted housing portion having a first end connected to the sleeve and a second end extending outwardly therefrom creating a mop head receiving surface area between a portion of the handle and an inner surface of the housing. The housing is movable along the handle by way of the sleeve in a manner to removably enclose the mop head material and enable squeezing of the mop head material by virtue of its rubber-like characteristic wherein it can twist over itself to selectively reduce the receiving surface area.




Another aspect of the present invention is directed to a retrofit self-contained wringer for connection to a mop having a handle and mop head connected thereto. The retrofit self-contained wringer includes a sleeve frictionally movably disposed on the handle such that the sleeve is self supporting along a number of positions of the mop handle and a twistable rubber-like generally fluted housing portion having a first end connected to the sleeve and a second end extending outwardly therefrom creating a mop head receiving surface area between a portion of the handle and an inner surface of the housing. The housing is movable along the handle via the sleeve in a manner to removably enclose the mop head material and enable squeezing of the mop head material through its rubber-like characteristic wherein it can twist over itself to selectively reduce space between the handle and the receiving surface area.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring now to the drawings, the present invention relates the mop


10


having a self-contained wringer


12


. While the mop


10


and self-contained wringer


12


are shown together, it is intended as part of the present invention that the self-contained wringer


12


be part of the mop


10


at a point of purchase or as a separate item which may be retrofit to the mop


10


. Accordingly, both embodiments are in the subject matter in the claims appended hereto.




The mop


10


includes an elongated handle


14


, the self-contained wringer


12


(formed by a sleeve


16


and a housing


17


), retainer member


18


and an insert


22


. The retainer member


18


and insert


22


are provided to hold mop head material


24


on the handle


14


within the housing


17


. Optionally, a resilient scrub pad material as shown in commonly owned U.S. Pat. No. 6,108,848 which is incorporated herein by reference can be used herewith.




The handle


14


includes an end


26


which may also have an eyelet cap


28


connected thereto to permit the mop


10


to be hung when not in use. The handle


14


has another end


30


formed with a threaded surface for connection to retainer


18


.




The sleeve


16


has an inside portion


19


which has a plurality of frictionally engaging fingers


21


which bias against the handle


14


as seen in

FIG. 7

in a manner which sufficiently hold the sleeve


16


and associated housing


17


in place while permitting the same to be slid to a desired position along the handle


14


.




The housing


17


is further characterized to be generally fluted and has an end


23


connected to an end


25


of the sleeve


16


. The sleeve


16


can be made of a plastic material, such as a thermoplastic polymer. A space between the handle


14


and housing


17


forms a receiving surface area


27


. The housing


17


can be made of a rubber-like material, such as latex, with the particular characteristic that the housing


17


enable squeezing of the mop head material through its rubberlike characteristic wherein it can twist over itself to selectively reduce the receiving surface area


27


. A further characteristic of the housing


17


attributable to its rubber-like material is its ability to act as a rubber love keep water from the user's hands. The thickness of the housing


17


is such to provide sufficient durability as well as ease of twistability.




The diameter of the end


23


is about half that of the end


29


in order to accommodate receiving the mop head material


24


, but may take on other shapes to carry out the invention herein. The housing


17


has a series of recessed surface portions


31


longitudinally extending along the exterior of the housing


17


. The surface portions


31


as shown here are concave with the curved surface radially inward which aids one in gripping the outside surface of the housing


17


for twisting purposes while its inner surface so configured is less likely to ,rip and twist the mop head material


24


during the twisting of the housing


17


.




The retainer member


18


has an end


40


which is formed with an inner threaded surface threaded in a complementary manner to receive threaded end


30


of the handle


14


. Another end


46


is includes an inner retention surface


48


to receive a snap-fit male head


60


the insert


22


.




The mop head material


24


includes a series of strips of absorbent and durable material as is known in the art, such as woven or unwoven natural or cotton yarn or synthetic materials. For example, the materials may be made of plastic, such as polyester, polyurethane or polyether, or of natural, such as cotton, for example. As shown in the present invention, but not to be limiting, the mop head material


24


is formed with a series of generally parallel cuts to create individual intermediate strips which are joined at an open center surface of each strip, wherein the head


60


of the insert


22


goes through the center surface and is connected to the surface


48


. The insert


22


has a retention head


61


which is configured to binds and locks the ends


52


of the mop head material


24


against mop receiving surface


47


.




By so providing the structure of the mop described herein, the present invention results in a new and improved mop having a self-contained wringer. A novel aspect of the invention is to provide the selectivity of degree of water removal in a manner which controls water flow out the end


29


of the housing


17


. The design shown is less likely cause water to be spilled onto the user. The mop has the improved ability to fully use the mop head material with the wringing device being relatively lightweight and which is readily retractable from the mop head material in a manner which allows peripheral access to the mop head.




The mop is relatively simplistic and inexpensive to manufacture. The self-contained wringer is retrofit ready for use with substantially any conventional wet-deck type mop. The wringer now provides multipurpose of squeezability, controllability, wringability with minimal damage to the mop head material. In addition, the second sleeve provides a squeezing aid which is used to reduce the housing's mop head receiving surface as it is moved over the housing toward the second end of the housing.




The above described embodiment is set forth by way of example and are not for the purpose of limiting the present invention. It will be readily apparent to those skilled in the art that obvious modifications and variations can be made to the embodiment without departing from the scope of the invention. Accordingly, the claims appended hereto should be read in their full scope including any such modifications and variations.
