SUMMARY OF THE INVENTION
The cylinder attachment to wring water out of a mop comprises a frusto-conical shaped cylinder having a neck that is slidably attached to a mop handle. The mop handle has two clips to hold the cylinder up on the handle when the cylinder is not in use. The cylinder has an array of apertures in its lower, wider portion that allow for release of the mop water when the cylinder is lowered over the dirty, water-laden mop head to squeeze out the gray water. At least one aperture is located above the array of apertures to drain water that is squeezed from the top of the mop head as it collects inside the cylinder.
The reduced neck of the cylinder has an adjustable knob that enables the cylinder to be secured into position on the mop handle when the mop is used for scrubbing and mopping, or while the mop is in storage. The adjustable knob tightens a band that slips around the inside surface of the reduced neck of the cylinder so that the band secures around the mop handle. A groove may be cut into the inside surface of the neck into which the band shall sit. Alternatively, the band may surround the outside of the reduced neck to tighten the neck down against the mop handle, or the neck may be molded with two protrusions which can be tightened together by turning a threaded bolt. Any other conventional manner for tightening the cylinder in place along the mop handle may be used according to the present invention.
The lower end of the cylinder contains a rubber O-ring that both seals the cylinder when the mop is being compressed inside the cylinder to squeeze the water out and provides a softer edge when the mop is being pushed across the floor. When the cylinder is secured in place along the mop handle so that just one or two inches of mop strings extend beyond the end of the cylinder, the mop can be used for scrubbing. The rubber O-ring prevents the cylinder from scratching the floor during this scrubbing use.
Just above the O-ring, the inside of the cylinder flares out slightly to create an expansion lock, into which the mop strings are pushed when compressed. This expansion lock then holds the compressed mop strings inside the cylinder as the mop is lifted from the bucket. The expansion lock may have any profile, so long as the middle portion of the expansion lock is wider than the main portion of the cylinder and the bottom opening of the cylinder inside the O-ring. Any other convention, such as a restrictor ring, that is located at the end of the cylinder and has a smaller diameter than the cylinder to prevent the mop strings from coming out of the cylinder may be used in alternative to an expansion lock.
A specially adapted rinsing bucket is provided with a crescent shaped tray having an apertured bottom and an open front for accepting the mop head. The apertured bottom of the tray sits several inches above the bottom of the bucket, and allows the mop to be squeezed into the bucket without coming in contact with the water already sitting in the bucket. A support fence runs across the edge of the apertured bottom of the tray on the open front. This support fence prevents the apertured bottom from bending or giving when the mop and cylinder are compressed against the apertured bottom. The vertical wall of the tray extends further around the wall of the bucket, and a clip is attached to the extended part of the vertical wall above the open bottom of the bucket. The reduced neck of the cylinder can be secured in the clip so that the mop is held with the bucket and tray when in storage. The extended wall of the tray also includes a hole through which the end of the handle of the bucket passes, to secure the tray to the bucket.
Accordingly, it is a principal object of the invention to provide an in situ wet mop wringer device slidably attached to a mop handle according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The present invention is directed in FIGS. 1 to 3 to a combination of a cylinder attachment device, designated generally as 10 in the drawings, attached on a mop handle 12. The cylinder attachment 10 is held in place by a pair of clips 14 at the top of the mop handle 12 when the mop is in use. A mop connector 16 at its distal end holds the releasable mop head 18 made of conventional cloth strands. The mop handle 12 has an aperture 20 at its proximate end for hanging on a wall.
The cylinder attachment 10 (cross-sectioned in FIGS. 1 and 2) has at its top a reduced neck portion 22, optionally having an O-ring around its inside surface that stabilizes the attachment 10 on the mop handle 12. The lower end of the reduced neck 22 has an adjustable knob 11 that allows the cylinder attachment 10 to be fixed in position anywhere along the mop handle 12. The adjustable knob 11 shown in FIGS. 1 to 3 is turned to tighten a band that runs around the inside surface of the reduced neck 22, securing the band around the mop handle 12. The band passes through a slot in the reduced neck 22, so that it may be accessed by the knob 11 outside of the reduced neck 22.
Below the reduced neck 22, the cylinder attachment 10 has a frusto-conical portion 24 and an enlarged cylindrical portion 26. An array of apertures 28 pass through the lower end of the enlarged cylindrical portion 26, allowing water to be released from the enlarged cylindrical portion 26 when the mop head 18 is compressed inside the enlarged cylindrical portion 26. At least one aperture 29 is located above the array of apertures 28, so that when the mop head 18 is compressed, any water that is squeezed out of the top of the mop head 18 can be released from the cylinder 10.
The enlarged cylindrical portion 26 has an enlarged open bottom 30 of the same diameter as the enlarged cylindrical portion 26. The enlarged open bottom 30 contains a rubber O-ring 32. The rubber O-ring 32 seals the bottom 30 when the mop head 18 and cylinder 10 are pressed against a sink bottom 34 (FIG. 2) or the bottom of the pail 36 (FIG. 3). The rubber O-ring 32 also prevents the enlarged cylindrical portion 26 from scratching the floor during mopping or scrubbing by providing a softer contact surface.
The inside surface of the enlarged cylindrical portion 26 flares out in the area above the rubber O-ring 32 but below the array of apertures 28, defining an expansion lock 37. The expansion lock receives the ends of the mop head 18 strings when the mop head 18 is compressed, and holds the strings in the cylinder attachment 10 when the mop is lifted from the sink 34 or pail 36. By holding the strings in the cylinder attachment 10, the expansion lock 37 allows the mop head 18 to be compressed and generally dried inside a bucket full of water by not allowing the water to soak back against the mop head 18 when the compression pressure is released and the mop is removed from the bucket.
In FIG. 3, the rinsing pail 36 has a conventional handle 38. The pail 36 is modified with a crescent-shaped holding tray 40 attached to its rim. The tray 40 has a clamp 42 for attaching the reduced neck 22 to hold the mop for storage. The tray 40 has an open front and apertures 44 at its bottom 46 for drainage of the mop head 18. A support fence 45 stretches across the bottom of the open front along the edge of the apertured bottom 46 of the tray 40. The support fence 45 strengthens the bottom 46 so that it does not bend when the mop head 18 is compressed against the bottom 46. The apertured bottom 46 sits several inches above the bottom of the pail 36, allowing the apertured bottom 46 to remain above the rinsing water 48 that sits in the pail 36.
The tray 40 has a vertical wall 47 that runs around the inside of the sidewall of the pail 36. The vertical wall 47 extends further around the side of the pail 36 than does the apertured bottom 46. The pail handle 38 passes through a hole 49 in the vertical wall 47, removably securing the tray 40 to the pail 36. The clamp 42 for holding the mop in storage is attached to the vertical wall 47 above the open bottom of the pail 36. The clamp 42 is positioned away from the apertured bottom 46 so that the mop head 18 can be compressed against the apertured bottom 46 without the mop handle 12 being obstructed by the clamp 42.
Exemplary dimensions of the cylinder attachment device 10 are as follows:
Mop handle 12: Cylindrical, approximately 1 in. diameter, 3.5 ft. in length, metal, plastic or wood.
Mop head 18: Conventional cloth strands.
Clips 14: A pair, spring metal, snap to fit around 1 in. handle.
Cylinder attachment device 10: Metal or plastic, 20 in. height (or about 3 in. longer than mop head 18), neck portion 22 6 in. length including the frusto-conical portion 24; enlarged cylindrical portion 26, 14 in. length and 2 in. diameter; array of apertures 28 approximately 0.1875 in. diameter; additional aperture 29 approximately 0.1875 in. diameter; rubber O-ring 32 at the distal end or bottom of device approximately 2 in. diameter; expansion lock 37 approximately 0.5 in. wider than enlarged cylindrical portion 26.
Thus, a combination of a mop having a wringer cylinder attachment and a rinsing pail with a mop holder has been shown.
It is to be understood that the present invention is not limited to the embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
