The present invention is related to floor mopping apparatuses. More specifically, the present invention is related to mechanical devices for mopping a floor while being pushed there-about, and having replaceable cleaning sheets and means for spraying cleaning fluid toward the floor to be mopped.
Floor mopping apparatuses are well known and commonly used for mopping and removing spills and residue from hard surfaces, such as wooden, tiled, and linoleum-covered floors. A common type of handheld floor mop includes an elongate pole having a proximal end with a handle for grasping and a distal end pivotally connected to a mopping head, such as those taught in US Patent Application Publication 2006/0191557. Some of these mopping apparatuses also include replaceable disposable cleaning sheets which are removably affixed to the mop's head, such as those taught in U.S. Pat. No. 6,098,239 and U.S. Pat. No. 6,651,290. And some of these mopping apparatuses also include reservoirs for containing a cleaning fluid and means for spraying or otherwise applying the fluid onto the surface to be mopped, such as those taught in U.S. Pat. No. 6,986,619, U.S. Pat. No. 7,182,537, and US Patent Application Publication 2008/0066789.
A disadvantage common to prior art floor mops of the aforementioned type is in the efficacy with which such mops remove spills and residues. One disadvantage lies in the shapes of the heads of mops of the prior art, which make it difficult to gain full access to many areas of a typical floor, such as in corners and around table and chair legs and other furnishings.
Another disadvantage of mops of the prior art lies in their affixation means of disposable cleaning sheets, which typically require a burdensome amount of effort to sufficiently affix the sheets to the mop heads or which provide insufficient securement of the sheets to the head.
Another disadvantage of mops of the prior art having means for spraying or otherwise applying cleaning fluid lies in their inability to apply the fluid to many areas of the typical floor or to other surfaces to be cleaned besides the floor.
There exists a need for improvement in a floor mopping apparatus to more effectively remove spills and residue, and such is an object of the present invention.
There exists the need for optimization of the shape of the head of a floor mopping apparatus to allow access to more areas of a typical floor, such as in corners and around table and chair legs and other furnishings, and such is an object of the present invention.
There exists the need for optimization of the affixation means of disposable cleaning sheets to a floor mopping apparatus, to reduce the burden of sufficiently affixing the sheets to the mop heads while providing sufficient securement of the sheets to the head, and such is an object of the present invention.
There exists the need for improving the means for receiving, containing and applying cleaning fluid via a floor mopping apparatus, and such is an object of the present invention.
There exists the need for optimization of the means for spraying or otherwise applying cleaning fluid to more areas of the typical floor or to other surfaces to be cleaned besides the floor, and such is an object of the present invention.
Further needs and objects exist, which are addressed by the present invention, as may become apparent by the included disclosure of an exemplary embodiment thereof.
In one exemplary embodiment, the invention may be practiced in a floor mopping apparatus including an elongate pole and a mopping head, the elongate pole having a proximal end connected to a handle for grasping and a distal end pivotally connected to the mopping head and having a cleaning surface substantially coplanar with the floor to be mopped, wherein the cleaning surface has at least two adjacent peripheral cleaning edges connected at a corner of less than ninety angular degrees.
The cleaning surface may have a substantially triangular shape. The triangular shape may have at least one peripheral cleaning edge having a notch therein, the notch being at least approximately half of an inch deep and at least approximately one inch wide. The notch may be approximately centrally disposed in the at least one peripheral cleaning edge.
The triangular shape may be substantially equilateral. The at least one peripheral cleaning edge having a notch therein may be three cleaning edges each having a notch therein, the notches each being at least approximately half of an inch deep and at least approximately one inch wide.
The invention may also be practiced in a floor mopping apparatus including an elongate pole and a mopping head, the elongate pole having a proximal end connected to a handle for grasping and a distal end pivotally connected to the mopping head, wherein the mopping head has a planar support surface substantially parallel with the floor to be mopped, a cleaning element from the group including an absorbent pad and a dusting sheet abutted against the support surface and having a planar cleaning surface disposed substantially parallel with the support surface, and three fastening elements for removably securing the cleaning element to the mopping head, wherein the three fastening elements are substantially disposed in equal spacings about the mopping head.
The mopping head may have substantially the shape of an equilateral triangle. The fastening elements may each be disposed substantially adjacent a different corner of the equilateral triangle.
The mopping head may have three receiving fasteners and the cleaning element may be a dusting sheet substantially the shape of an equilateral triangle and the three fastening elements may each have an extension protruding outwardly there-from adapted to be received by one of the receiving fasteners such that the fastening elements and fastening receivers, in combination secure the cleaning element to the mopping head. The extensions may each protrude outwardly from a different corner of the equilateral triangle.
The invention may also be practiced in a floor mopping apparatus including a mopping head, an elongate pole having a proximal end connected to a handle for grasping and a distal end pivotally connected to the mopping head, and an applicator having a reservoir for containing a cleaning fluid and a dispensing mechanism for dispensing the fluid there-from, wherein the applicator is detachably attachable to the apparatus and has a first state when attached to the apparatus wherein the applicator communicates with and is only adapted to dispense the fluid to the mopping head, and a second state when detached from the apparatus wherein the applicator portably dispenses the fluid apart from the apparatus.
The applicator may be the handle when in the first state. The dispensing mechanism may have a trigger and pump assembly for causing the fluid from the reservoir to an outlet port through a conduit, and the outlet port may be adapted to communicate with the mopping head during the first state. The trigger and pump assembly may be convertible between first and second positions and may be biased towards the first position, wherein the conduit is a resiliently flexible tube, wherein the pump causes the fluid from the reservoir during conversion from the first position to the second position, and wherein the trigger pinches the resiliently flexible tube during the first position to deny fluid through the flexible tube to the outlet port during the first position.
The floor mopping apparatus may further have a spraying nozzle, wherein the outlet port is adapted for attachment to the spraying nozzle during the second state.
Further features and aspects of the invention are disclosed with more specificity in the Detailed Description and Drawings of an exemplary embodiment provided herein.
Many aspects of the invention can be better understood with reference to the included drawings. The components in the drawings are not necessarily to scale, and all components may not be present in all views, emphasis instead being placed upon clearly illustrating the principles of the present invention. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Reference is now made to
Floor mopping apparatus 100 includes head portion 102, pole portion 104, and handle portion 106. Head portion 102 has equilateral triangular head 110 with a fitting 112 hingedly attached thereto by a universal joint 114. The fitting has a female coupling portion 116 at its upper end for receiving the pole portion.
Pole portion 104 includes two pole segments; upper pole segment 120 and lower pole segment 122. Handle portion 106 is pistol-shaped and has a male coupling portion 124 at its forward end.
Each pole segment includes an identical male coupling portion, 126L on the lower pole portion and 126U on the upper pole portion, at its lower end, and a female coupling portion at its upper end. Upper female coupling portion 128 atop the upper pole segment is adapted to receive male coupling 124, and lower female coupling portion 130 is adapted to receive upper male coupling 126U.
Depending on whether the mop is to be used in its full-length mode of

The tabs 146 may be made of the same material as the sheet 144, and may be made integrally there-from or attached thereto, or the tabs may be made of any thin and soft fabric-like or paper-like material bonded to the sheet adjacent its corners. The retaining clips are preferably of the common “pinching” type such as those taught in U.S. Pat. No. 6,098,239 and U.S. Pat. No. 6,651,290, the teachings thereof being incorporated herein by reference, or of any similar arrangement having an open pocket into the head covered by rubber-like film which has a slitting there-through. The associated tab of the sheet is pushed through the slitting and into the pocket and pinched by the rubber-like film, and the tabs may be easily pulled from the retainers for removal and disposal of the sheet, leaving the retainers unchanged for reception of the next sheet.
The equilateral triangular spacing of the three clips is found to be optimal in several respects;
The tabs may be alternatively configured, such as in pairs adjacent each corner 148 of the sheet extending outwardly from opposite side edges of the corner, and the retaining clips may be substituted with any reasonable means of temporarily affixing the sheet to the head. Further reference to head portion 102 or head 110 thereof assumes that either of a pad 138 or a wiping sheet 144 is affixed thereto, whether or not such are omitted from the drawings for simplification thereof.

Having head corners with an exclusive angle substantially less than ninety angular degrees on a mop head that is centrally and pivotally connected to the pole provides additional benefit and efficacy. As the mop head is moved into floor corners or other such tight spaces with the handle held firmly, and as the head corners contact the walls or other obstructions, the offset disposition of the universal joint from the contacting head corner causes the mop head to pivot about the universal joint and pole, which causes a twisting interaction between the cleaning surface of the mop head and the soiled floor corner. Such twisting interaction is found to improve cleaning in floor corners over purely linear in and out interaction.
Having three acute head corners evenly spaced about a mop head that is centrally and pivotally connected to the pole is advantageous in that it allows improved access and simplified mopping into other tight spaces, and improves cleaning. As the mop head is moved about the floor with the handle held firmly, and as the head corners contact obstructions, the offset disposition of the universal joint from the contacting head corner causes the mop head to pivot about the universal joint and pole, which causes a twisting interaction between the cleaning surface of the mop head and the soiled floor. Such twisting interaction is found to improve cleaning over purely linear interaction between the mop head and floor.
The sides of the triangular head are approximately eleven inches long, and each include notches 136 depressed into the middle of each for providing improved access to the floor around such obstructions as table legs and the feet of furnishings. The notches are each semi-circular in shape and defined by a notch radius of approximately one and a half inches, each have a notch width measured along the side of the head of approximately two inches, and each have a notch depth measured into the side of the head of approximately three-quarters of an inch.

The diverter valve is a flapper valve arranged to cause fluid flow, depending on the direction of flow, only from either feed tube 154B to pump tube 160, as seen in the inset of
The pump is fixedly disposed within handle 106 and includes a cylindrical body 174 housing a piston 172 longitudinally and sealingly movable there-within. Extension spring 176 within the body causes extension of piston 172 to expand the hollow chamber within the body. Compression of piston 172 against the bias of spring 176 reduces the volume of the chamber inside body 174 and forces air (initially) or fluid (after the pump has been primed) there-from through pump tube 160.
Trigger 166 is pivotally attached within handle portion 106 and, depending on its position, serves to either actuate pump 162 or to pinch dispensing tube 164. The trigger has a pump interfacing surface 170 that contacts the pump's piston 172 so that the trigger is biased by the piston and extension spring 176 to the forward position shown in

Female coupling portion 130 includes hole 192 and male coupling portion 126U includes inwardly flexible headed clip 194. Depression of the resilient headed clip 194 allows the male coupling portion to be slid within the female coupling portion until the head of clip 194 aligns with hole 192, and springs outwardly there-into to temporarily secure the coupling portions together. Forced depression of clip 94 back through hole 192 releases this securement and allows decoupling.
As the male and female coupling portions are being connected, tubular male valve 196 of the male portion slides sealingly into receiving tunnel 198 of the female portion. O-rings 200 surrounding valve 196 seal against the cylindrical inner wall of the tunnel. The valve is connected to tube 202 passing through pole portion 120 and leading from the handle's dispensing tube 164 (not shown). And the tunnel is connected to tube 204 passing through pole portion 122 and leading to head nozzle 182 (not shown).
Spring 206 within valve 196 biases valve stop 208 against inwardly directed flange 210 at the distal end of the valve to close the valve when the coupling is uncoupled. During insertion of the valve into the tunnel, as stop 208 contacts flow-through valve actuator 212 at the bottom of tunnel 198, the valve is pushed open against the bias of spring 206 to create a continuous fluid path through the coupling from tube 202 to tube 204, and thereby from tube 164 (not shown) to head nozzle 182 (not shown).
The removable valve cap 214 is fluidly connected to intake tube 154A within the reservoir and includes a normally closed valve so that after the reservoir is filled with fluid and the cap is threaded snuggly thereon, the reservoir is sealed to prevent inadvertent leaking. When reservoir coupling 156 is threaded forwardly against the valve cap, the cap's valve is forced open by the coupling, and feed tube 154B, which is in fluid communication with the reservoir coupling, is brought into fluid communication with intake tube 154A, so that fluid drawn from the reservoir by the afore-described pumping system is drawn through intake tube 154A, cap 214, coupling 156, feed tube 154B to diverter valve 158, for dispensing as previously described.
Removal of the reservoir from the handle without retraction of coupling 156 is denied by capture of cap 214 by the coupling when in its threaded-in position, which prevents inadvertent removal, such as by a tampering child. The reservoir is preferably blow-molded of a transparent or translucent material to allow viewing of the amount of fluid therein.
While the invention has been shown and described with reference to a specific exemplary embodiment, it should be understood by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention, and that the invention should therefore only be limited according to the following claims, including all equivalent interpretation to which they are entitled.
