Abstract

A mop pad support includes a frame configured to retain a mop pad, a handle for controlling the frame, and a connecting mechanism that connects the handle to the frame. The frame has a longitudinal direction and a latitudinal direction. The frame is longer in the longitudinal direction than in the latitudinal direction. The handle has a shaft portion that extends in a substantially longitudinal direction and a grip portion that extends at an angle relative to the longitudinal direction. The grip portion is located farther from the frame than the shaft portion and has ends proximal and distal the shaft portion. The proximal end of the shaft portion is disposed lower than the distal end, such that the grip portion extends upward. The connecting mechanism is configured to permit the handle to rotate about a first axis that is substantially parallel to the longitudinal direction of the frame and to rotate about a second axis that is substantially parallel to the latitudinal direction of the frame.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS
• This application claims priority to U.S. Provisional Application Nos. 60/567,794 (filed May 5, 2004), 60/637,440 (filed Dec. 21, 2004), and 60/646,986 (filed Jan. 27, 2005), which are incorporated herein by reference in their entirety.
BACKGROUND
• Flat mops typically include a handle attached to a frame, which is configured to hold a flat mop pad. The handle is used to control the frame and mop pad. Like conventional string mops, the handle of the flat mop can be used to control the movement of the frame and mop pad in forward/backward and side-to-side motions. Flat mops, however, impose an additional requirement that generally does not exist with conventional string mops. Specifically, flat mops often require that the handle be capable of controlling the rotational movement of the frame and mop pad. This rotational movement of the frame and mop pad occurs when a user moves the mop in a figure eight motion while walking backwards—a mopping technique that can be used with flat mops.
• Often the handle of a flat mop is merely a straight member. With such a handle it can be difficult to control rotational movement of the frame and mop pad. Moreover, the ergonomics of such a handle can be inconvenient for some users.
• In effort to reduce the problems associated with a straight-handled flat mop, PCT Application WO 98/12023 suggests providing a downward angled ergonomic grip at the end of a straight handle. This approach is less than desirable. This downward angled grip is not efficient when mopping floors using the figure eight technique. The downward angled grip positions the user's wrist at an awkward angle and forces the user to shorten the length of the handle, which reduces the effective width of coverage of the figure eight motion.
SUMMARY
• An aspect of the present invention relates to a mop pad support comprising a frame configured to retain a mop pad, a handle for controlling the frame, and a connecting mechanism that connects the handle to the frame. The frame has a longitudinal direction and a latitudinal direction. The frame is longer in the longitudinal direction than in the latitudinal direction. The handle has a shaft portion that extends in a substantially longitudinal direction portion is located farther from the frame than the shaft portion and has ends proximal and distal the shaft portion. The proximal end of the shaft portion is disposed lower than the distal end, such that the grip portion extends upward. The connecting mechanism is configured to permit the handle to rotate about a first axis that is substantially parallel to the longitudinal direction of the frame and to rotate about a second axis that is substantially parallel to the latitudinal direction of the frame.

DETAILED DESCRIPTION
• Presently preferred embodiments of the invention are illustrated in the drawings. An effort has been made to use the same or like reference numbers throughout the drawings to
• A first embodiment of a mop pad support10 according to the present invention is shown inFIGS. 1-9. Themop pad support10 includes aframe20, ahandle30, and aconnecting mechanism40.
• Theframe20 is configured to retain amop pad50. Theframe20 can be aconventional frame20 used in mop pad supports. Preferably, it is formed ofextruded aluminum21 with plastic end stops22 (seeFIG. 3). As shown in the top view ofFIG. 3, theframe20 has alongitudinal direction23 and a latitudinal direction24 (portions of theconnecting mechanism40 andhandle30 have been removed for clarity). Preferably theframe20 is longer in thelongitudinal direction23 than in thelatitudinal direction24.FIG. 4 is a bottom view of theframe20 with themop pad50 removed. As shown inFIG. 4, theframe20 can include, for example, VELCROfastener strips26 that connect to corresponding VELCRO fastener material (not shown) on themop pad50 to hold themop pad50 in position on theframe20.
• Thehandle30 is configured to control theframe20. Thehandle30 has ashaft portion31 and agrip portion32. Though thehandle30 can be a telescoping adjustable member, as is conventional in the art, an integral member, or any other suitable configuration.
• Theshaft portion31 preferably extends in a substantially longitudinal direction33 (seeFIG. 5). Though deviations from a straight line are permissible, it is desirable that theshaft portion31 be substantially straight. Materials, such as plastic grips (not shown), can be disposed on theshaft portion31 to provide a better grip for a user.
• Thegrip portion32 is configured to be gripped by the hand of a user. As shown inFIG. 5, thegrip portion32 preferably extends in adirection34 that is at an angle α relative to the longitudinal direction of theshaft portion31. The angle α preferably is at least 30 degrees. Thegrip portion32 is located farther from theframe20 than theshaft portion31. Preferably, thegrip portion32 extends from theend35 of theshaft portion31. Thegrip portion32 can include aplastic member38 that provides a better grip for a user.
• Thegrip portion32 has anend36 proximal theshaft portion31 and anend37 distal theshaft portion31. As shown inFIG. 5, theproximal end36 of thegrip portion32 is disposed lower than thedistal end37, such that thegrip portion32 extends upward.
• The connectingmechanism40 connects thehandle30 to theframe20. The connectingmechanism40 can be a conventional connecting mechanism used for flat mop supports. Preferably, the connectingmechanism40 includes a conventional quick connect/disconnect mechanism that facilitates fast attachment and removal of thehandle30
• The connectingmechanism40 is configured to permit thehandle30 to rotate in a direction41 (seeFIG. 7) about a first axis42 (seeFIGS. 6 and 7) that is substantially parallel to thelongitudinal direction23 of theframe20. The connectingmechanism40 also is configured to permit thehandle30 to rotate in a direction43 (seeFIG. 6) about a second axis44 (seeFIGS. 6 and 7) that is substantially perpendicular to the first axis42 (though the axes do not necessarily intersect).
• The configuration of connectingmechanism40 permits thegrip portion32 to rotate about an axis that is substantially coincident with thelongitudinal direction33 of thehandle30 to cause a corresponding rotation of theframe20. As shown inFIG. 8, rotation of thegrip portion32 in the direction of the arrow A (about the axis substantially coincident with the longitudinal direction33) and rotation of theshaft portion31 in the direction of arrow B (about the axis44) causes a corresponding rotation of theframe20 in the direction of arrows C. Conversely, as shown inFIG. 9, rotation of thegrip portion32 in the direction of the arrow A′ (about the axis substantially coincident with the longitudinal direction33) and rotation of theshaft portion31 in the direction of arrow B′ (about the axis44) causes a corresponding rotation of theframe20 in the direction of arrows C′.
• The mop pad support of the present invention is an improvement over flat mops having a straight handle because it provides anergonomic grip portion32 that facilitates control over the rotation of theframe20 andmop pad50. Themop pad support10 of the present invention also is an improvement over a downward angled grip at the end of a straight handle, because the upwardly angled grip portion of the present invention can be configured to allow the user to grip the handle in a comfortable position that provides superior control and/or turning of the frame on the floor. This makes execution of the figure eight mopping technique more efficient because the user's grip on the handle can be lighter, allowing him or her to mop longer without fatigue.
• Themop pad support10 of the present invention can be configured in a variety of ways in addition to those already described. For example, thehandle30 of the present invention can be configured in a variety of embodiments, some of which are shown inFIGS. 10-16.
• As another example, as shown inFIGS. 17 and 18, the frame can be modified to include asqueegee blade60 made of, for example, rubber. Thesqueegee blade60 preferably extends from a forward edge of the modifiedframe120. In this configuration, the connectingmechanism40 preferably includesprojections70 that fit intodetents72 to inhibit rotation by of rotation, thesqueegee blade60 is kept in position and ready to be used. Thissqueegee blade60 can be used, for example, to squeegee wet spills and to sweep dry dirt and debris. The user can execute the figure eight technique described above in regard to mopping.
• Themop pad support10 of the present invention can be used with many types ofmop pads50. Preferably, it is used with a mop pad disclosed in a patent application that is to be concurrently filed by Judy Cline entitled “Color Coded Mop Pads and Method of Color Coding Same” (Ser. No. ______; Attorney Docket Number 086554-1178), the entire contents of which is hereby incorporated by reference.
• Themop pad support10 also can be used with many types of buckets. A preferred mop bucket is disclosed in a patent application that is to be concurrently filed by the present inventor and Craig Rogers entitled “Bucket With Foot Pedal Wringer Mechanism and Scrub Board” (Ser. No. ______; Attorney Docket Number 086554-1173), the entire contents of which is hereby incorporated by reference. Another preferred bucket, which is used for disinfecting, is disclosed in a patent application that is to be concurrently filed by the present inventor entitled “Disinfecting Bucket” (Ser. No. ______; Attorney Docket Number 086554-1172), the entire contents of which is hereby incorporated by reference.
• It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit and scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and
