Abstract

A mop having a base plate, a handle, a joint connecting the plate to the handle, a first grip at the end of the handle, a scrubbing mechanism in the base, and a cleaning pad attached to the bottom of the base. The scrubbing mechanism includes a scrub bar, and is movable between an inactive position in which the bar is flush with or above the lower surface of the plate, and an active position in which the bar extends through an opening through the plate to be at least partially below the lower surface of the plate. The cleaning pad moves from being flat on the lower surface of the plate when the scrubbing mechanism is in the inactive position, and a second configuration in which at least a portion of the cleaning pad protrudes downwards from the lower surface when the scrubbing mechanism is in the active position.

Claims

1. A mop comprising:

a base plate having a generally flat lower surface configured to face a surface to be cleaned and a base plate opening through the lower surface;

a handle having a proximal end, a distal end opposite the proximal end, and a handle axis extending form the proximal end to the distal end;

a joint connecting the proximal end of the handle to the base plate;

a first grip connected at the distal end of the handle;

a scrubbing mechanism comprising a scrub bar having a curved or polygonal cross-section, the scrubbing mechanism being movably mounted to the base plate and configured to move between an inactive position in which the scrub bar is flush with or above the lower surface of the base plate, and an active position in which the scrub bar extends through the base plate opening to be at least partially below the lower surface of the base plate;

a cleaning pad selectively connectable to the lower surface of the base plate, the cleaning pad being movable between a first configuration in which the cleaning pad lies flat on the lower surface when the scrubbing mechanism is in the inactive position, and a second configuration in which at least a portion of the cleaning pad protrudes downwards from the lower surface when the scrubbing mechanism is in the active position; and

a base actuator movably mounted to the base plate and operatively associated with the scrubbing mechanism to move the scrubbing mechanism from the inactive position to the active position;

wherein the base actuator comprises a sliding actuator having one or more ramps configured to contact the scrubbing mechanism and move the scrubbing mechanism from the inactive position to the active position upon sliding the sliding actuator relative to the base plate from a first sliding actuator position to a second sliding actuator position;

wherein the base actuator further comprises a drive lever pivotally mounted on the base plate and operatively associated with the sliding actuator to move the sliding actuator from the first sliding actuator position to the second sliding actuator position upon rotating the drive lever from a first drive lever position to a second drive lever position; and

wherein the drive lever is operatively associated with the sliding actuator by one or more tabs that extend from the drive lever and engage one or more corresponding slots in the sliding actuator.

2. The mop of claim 1, further comprising one or more springs operatively associated with the scrubbing mechanism and configured to bias the scrubbing mechanism from the active position to the inactive position.

3. The mop of claim 2, wherein the springs comprise cantilevered springs that are integrally formed with the scrubbing mechanism.

4. The mop of claim 1, wherein the handle comprises a handle actuator movably mounted to the handle and operatively associated with the drive lever to move the drive lever from the first drive lever position to the second drive lever position upon moving the handle actuator from a first handle actuator position to a second handle actuator position.

5. The mop of claim 4, wherein the handle actuator further comprises a grip lever mounted to the handle on a grip handle pivot to rotate between a first grip handle position corresponding to the first handle actuator position to a second grip handle position corresponding to the second handle actuator position.

6. The mop of claim 5, wherein the grip handle pivot has a pivot axis that is generally perpendicular to the handle axis.

7. The mop of claim 4, wherein the handle actuator further comprises a rod operatively connected to the grip handle and movable from a first rod position when the grip handle is in the first grip handle position to a second rod position when the grip handle is in the second grip handle position, and wherein the rod contacts and moves the drive lever to the second drive lever position when the rod is in the second rod position.

8. The mop of claim 5, wherein the grip lever is generally parallel to the handle axis when the grip lever is in the first grip handle position, and generally perpendicular to the handle axis when the grip lever is in the second grip handle position.

9. The mop of claim 1, wherein the handle comprises a handle actuator operatively associated with the base actuator and movable to an active handle actuator position in which the handle actuator acts on the base actuator to move the scrubbing mechanism from the inactive position to the active position.

10. The mop of claim 9, wherein the joint comprises a pivoting joint that is configured to allow the base plate to rotate relative to the handle about at least a first axis, and wherein the handle actuator further comprises a rotation lock configured to selectively prevent the base plate from rotating relative to the handle about the first axis when the handle actuator is in the active handle actuator position.

11. The mop of claim 10, wherein the joint is configured to allow the base plate to rotate relative to the handle about a first axis and a second axis.

12. The mop of claim 11, wherein the rotation lock is configured to selectively prevent the base plate from rotating relative to the handle about the first axis and the second axis when the handle actuator is in the active handle actuator position.

13. The mop of claim 10, wherein the handle actuator comprises a rod movable along the length of the handle, the base actuator comprises a drive lever pivotally mounted to the base plate, and the rotation lock comprises an end of the rod that fits into a divot formed on the drive lever.

14. The mop of claim 10, wherein the rotation lock comprises a sheath that is movably mounted on the handle to move to an active lock position in which the sheath surrounds at least a portion of the joint when the handle actuator is in the active handle actuator position.

15. The mop of claim 14, wherein the sheath comprises a flared-out base configured to contact an upper surface of the base plate to help hold the base plate at a fixed orientation relative to the handle when the sheath is in the active lock position.

16. The mop of claim 1, further comprising a fluid deposition system operatively associated with the mop and comprising:

a tank configured to hold a supply of liquid;

a pump fluidly connected to receive the liquid from the tank;

a sprayer fluidly connected to receive the liquid from the pump; and

a trigger configured to operate the pump to deposit liquid through the sprayer and onto the surface to be cleaned.
