CLEANING IMPLEMENT
A self-wringing cleaning implement including a cleaning assembly equipped with a platen and a compression member constructed and arranged for relative movement. The cleaning assembly further includes a cleaning member having an absorbent body and a porous cover releasably securable to the platen. During wringing, relative linear movement between the platen and the compression member compresses the absorbent body to force liquid contained therein through the openings in the porous cover. Conversely, relative linear movement between the platen and the compression member in the opposite direction relieves pressure on the absorbent body whereby the implement is configured to resume cleaning of a surface. The implement may also include a scrub brush for removing especially stubborn soil from a surface.

The present invention relates in general to cleaning implements and in particular to self-wringing cleaning devices.
BACKGROUND OF THE INVENTIONSelf-wringing cleaning devices in the form of wet mops are well known in the art. A typical wet mop comprises an elongate handle the lower end of which carries a base member or retaining means carrying absorbent material such as cloth strips, cloth strands or sponge-like material. As is known, during mopping a user swabs the mop across a floor surface to either clean the floor or remove excess fluid from the floor. As is also known, the user periodically wrings fluid from the absorbent material so that swabbing may proceed. Several different methods are known for performing the wringing process.
For example, cloth strand mops may be wrung by hand or also may be equipped with a self-wringing mechanism of any of a variety of constructions known in the art.
Similarly, sponge mops usually include a hand-operated wringer mechanism. One such wringer is a plate having a pivot axis extending generally parallel to the longitudinal axis of the sponge. Using such a device, a user grasps a handle connected to the plate and swings the plate into face-to-face contact with the sponge and squeezes fluid from the sponge. Another sponge mop is known as a butterfly mop. In a butterfly mop the sponge retaining means or platen is hinged at its center and the wringer mechanism includes a pair of rollers disposed on either side to the hinge atop the platen. During wringing, a wringer handle connected to the rollers via a linkage is pushed downwardly by a user. In so doing, the rollers contact opposite halves of the platen and pivot them inwardly toward one another thereby causing the sponge material to compress against itself to discharge fluid from the sponge. Another common sponge mop wringing mechanism includes a pair of opposed rollers extending parallel to the longitudinal axis of the sponge at forward and rearward faces thereof. As is known, the rollers are moved relative to the sponge, or vice versa, in order to squeeze liquid from the sponge.
Heretofore, however, sponge mops and other cleaning implements have not been equipped with a replaceable cleaning member that not only enhances the cleaning efficacy of the implement but that also cooperates with the device's wringer in order to effectively extract liquid from the device during a wringing operation.
An advantage exists, therefore, for a mop or other cleaning implement that is not only self-wringing but also employs a replaceable and durable cleaning member that works in conjunction with the wringing mechanism to provide both highly effective cleaning performance and liquid extraction from the cleaning member.
SUMMARY OF THE INVENTIONThe present invention relates to cleaning implements including, without limitation, self-wringing mops. In the exemplified embodiment, a self-wringing mop comprises a manually-operated wringer lever pivotally connected to the elongated shaft of a mop handle. A rod has an upper end connected to the lever and a lower end connected to one of a cleaning member support platen and a compression member. The other of the cleaning member support platen and the compression member is affixed to the handle whereby either the platen is movable relative to the compression member or the compression member is movable relative to the platen. The compression member includes a pressure plate and a superstructure. The superstructure of the compression member cooperates with corresponding superstructure of the platen to permit relative linear motion and, preferably, prevent relative rotational motion between the platen and the compression member.
A cleaning member comprising an absorbent body and a porous cover is adapted to be releasably securable to the platen. According to a preferred embodiment, the porous cover is preferably a durable scrim or mesh-like scrubbing material that is used to fasten the cleaning member to the platen.
In operation, movement of the lever in a first “wringing” direction causes relative linear movement between the platen and the compression member whereby the pressure plate compresses the absorbent body to force liquid contained therein through the openings in the porous cover. Conversely, movement of the lever in the opposite direction relieves pressure on the absorbent body whereby the mop is configured to resume swabbing of the floor surface.
So constructed, the present invention provides a cleaning implement with an integral wringing mechanism that cooperates with a replaceable absorbent cleaning member in order to merge the convenience of self-wringing with the cleaning advantages of scrubber material.
Additionally, the platen also preferably supports a scrub brush attachment that is selectively positionable into operative and inoperative positions. In the operative position, the attachment is securely retained relative to the platen whereby a scrub brush carried by the attachment can be used to scrub particularly hard to remove soil from a floor surface. In the inoperative position, the brush is movable relative to the platen to enable removal/replacement of the cleaning member. According to a preferred embodiment, the scrub brush is rotatable into at least two angular positions for optimum cleaning of differently oriented crevices in a floor or other surface.
Other details, objects and advantages of the present invention will become apparent as the following description of the presently preferred embodiments and presently preferred methods of practicing the invention proceeds.

A suitable but not non-limitative example of the sponge material may be a polyether material with a fine cell structure and a density of from about 1.25 to about 1.65 lbs/ft3. Likewise, a suitable but not non-limitative example of the fibrous material may be a bunched plurality of strands such as, for example, non-woven fibrous strands formed from flexible and compressible fibers. According to a presently preferred embodiment, such strands comprise 100% polyester microfiber, 300 denier, 288 filament strands infused with a 96% water and 4% polyester copolymer hydrophilic softener. Although not necessary, the fibers of the absorbent strands 34 are preferably bound by thread in order to produce a beaded, braided, helical other constrained strand configuration. Suitable strands for this purpose may include identification number MD010120001 yarn manufactured by Ningbo Sanbang Home Products Co. Ltd. Of Ningbo, China.
The porous cover 30 preferably comprises a durable natural or synthetic fiber net, mesh or scrim material and may envelope all or merely the floor-contacting or other surface cleaning face of the absorbent material. The mesh material must be porous yet capable of withstanding long- term use as a scrubbing material for removing stubborn soil from a floor surface. A preferred material is nylon fiber mesh.

The mop-wringing operation has thus far been described in connection with a movable platen 22 and a stationary compression member 48. However, it will be understood that the compression member may be linked to the wringer lever while the platen may be affixed to the mop handle. What is essential, however, is that there be relative linear movement between the platen and the compression member sufficient to exert enough tension on the flaps to effectively compress the absorbent material such that substantial quantities of fluid are discharged through the porous cover.
Finally, while the self-wringing functionality described herein has been manifested in the form of a wet mop, it will be understood that its essential features and principles may be adapted as well to hand-held cleaning apparatus. For example, a hand-held cleaning implement may include a platen to which the cleaning member is attached and a compression member operably connected to a movable handle. So constructed, squeezing of the handle causes movement of the compression member and corresponding expression of fluid through the porous cover in the manner described above.
Although the invention has been described in detail for the purpose of illustration, it is to be understood that such detail is solely for that purpose and that variations can be made therein by those skilled in the art without departing from the spirit and scope of the invention as claimed herein.
