Cleaning personnel normally uses a trolley with a bucket or other container for a liquid like water or a cleaning solution and some kind of squeeze out device fixedly mounted to the container to squeeze out the mop cover to the practical amount of liquid to be carried to the floor to be cleaned.
The prior art squeezing out device forming the starting point of the invention (WO 99/00050 Al) already provides a squeeze out structure which defines a generally flat squeeze out surface with a plurality of openings. The squeeze out surface in inclined from the horizontal preferably at an angle of about 45 within the squeeze out structure that is fixedly positioned on top of or within the bucket. The squeeze out surface itself is formed by a plurality of three dimensional squeeze out formations, in particular rods, rolls, balls, or the like which together define the plurality of openings therebetween.
-2-Instead of only pressing the mop cover towards the squeeze out surface this prior art squeezing out device provides for a means that enables movement of the mop holder with the mop cover attached thereto on the squeeze out formations back and forth, preferably sideways. This means is a. mop haridle engagement means above the squeeze out surface with an arrangement by which the user may apply pressure against the squeeze out surface. For enhanced liquid removal the mop cover on the mop holder may be moved from left to right and right to left in a reciprocating movement while. maintaining a slight backward pressure to insure that the mop cover remains pressed against the squeeze out formations. So removal of liquid from the mop cover is not only done by exerting pressure, but also by using a lateral relative movement between the mop cover and the squeeze out formations.
In this prior art the squeeze out formations are preferably rolls or balls that are as such rotatably mounted within a squeeze out frame structure. However it is disclosed that they may be stationary as well.
From further prior art a mop cover has become recently available (WO
2005/013793 Al) which comprises an additional part extending beyond the mop holder. This double size mop cover can be used for specific cleaning tasks in particular with a wet/dry cleaning combination.
For specific cleaning tasks three dimensional mop holders with assigned mop covers are used. A squeezing out device for removing liquid from a flat mop cover mounted on a three dimensional mop holder with two wings is known from prior art as well (WO 97/17008 Al). This squeezing out device has two cheek plates movable in relation to each other. When those cheek plates are in their top initial position they form a downwardly tapering entry gap for inserting.
the mop holder. By the exertion of perpendicular pressure with the aid of the handle the cheek plates can be moved downwardly from their top initial position squeezing out the mop cover on both sides of the mop holder to a bottom final position. However, this squeezing out device can not be used for a mop holder with wings extending at an acute angle relative to each other which has been proposed recently (WO 2005/013791 Al).

Similar to the system for a one sided mop holder disclosed in the initial prior art WO
99/00050 Al this squeezing out device according to the invention provides for two equally operative squeeze lo out surfaces.
Further embodiments of above mentioned versions of the inventive squeezing out device are the subject matter of further dependent claims.
Now, follows a description of preferred embodiments of the invention by way of example and with reference to the drawings. In the drawings:
Fig. 1 shows a first embodiment of the invention in a first position, Fig. 2 shows the squeezing out device according to Fig. 1 in a second position, however without a mop holder, Fig. 3 shows the first embodiment in a schematic side view, Fig. 4 shows a second embodiment of the invention in a schematic side view like Fig. 3, Fig. 5 shows a third embodiment of the invention in a top plan view, Fig. 6 shows a fourth embodiment in a schematic side view.
In Fig. 1 there is indicated a trolley 1 for a mopping system. The trolley 1 is provided with castors at each corner thereof and with an upstanding frame 2. In
-5-Fig. 1 there can be seen a mopping device with a flat mop cover 3 mounted on a mop holder 4. A handle 5 is attached to the top side of the mop holder 4 by means of a handle socket and a universal joint. This is a typical construction of such flat mop holder 4 which is widely disclosed in the prior art.
The system further comprises a bucket 6 that is positioned on the trolley 1.
In the embodiment shown in Fig. 1 and 2 there are two buckets 6, 7 arranged next to each other. One bucket 7 is for clean water or a cleaning solution, whereas the other bucket 6 is for squeezed out liquid and waste water. Instead of the buckets
The system further comprises a bucket 6 that is positioned on the trolley 1.
In the embodiment shown in Fig. 1 and 2 there are two buckets 6, 7 arranged next to each other. One bucket 7 is for clean water or a cleaning solution, whereas the other bucket 6 is for squeezed out liquid and waste water. Instead of the buckets
6, 7 other types of containers can be used.
Fig. 1 and 2 show a squeeze out structure 8 on top of the first bucket 6. This squeeze out structure 8 defines a generally flat squeeze out surface 9 with a plurality of openings. As the mopping device has been removed in Fig. 2 the openings are clearly visible.
The squeeze out surface 9 is formed by a plurality of squeeze out formations 10.
The squeeze out formations 10 can be formed by a large part like a sieve, a grid, a perforated plate structure or the like. In the present embodiment the squeeze.
out formations 10 are formed by rods extending parallel to each other, the distance between the rods defining the openings of the squeeze out surface 9.
From prior art documents squeeze out formations 10 as rods, rolls, balls, or the like are known.
Now, as can be seen in Fig. 1 and 2, this first version of a squeezing out device according to the invention is characterized in that the squeeze out structure comprises a squeeze out frame 11 mounted in a fixed position relative to the bucket 6 for positioning the mop holder 4 of the mopping device, the squeeze out formations 10 are positioned within a separate carrier structure 12, the carrier structure 12 is movable relative to the squeeze out frame 11 so that the mop holder 4 with the flat mop cover 3 can remain stationary on the squeeze out surface 9 within the squeeze. out frame 11, whilst the squeeze out formations are moved relative to the mop cover 3. As already explained in the introductory part of the description, in this system the mop holder 4 can be pressed with constant and high pressure against the squeeze out surface 9. Nevertheless, an efficient relative movement between the squeeze out formations 10 and the mop cover 3 is realized, here by movement of the squeeze out formations 10 relative to the stationary mop cover 3 which is positioned within the squeeze out frame 11.
In the present embodiment it is provided that the carrier structure 12 is a frame that is movable back and forth, preferably sideways, by means of an actuating lever 13, pivotally mounted to the squeeze out structure 8 and/or the bucket 6 and/or the trolley 1.
In the present embodiment the manual actuating lever 13 can be seen on the left side. Fig. 1 shows the left position of the carrier structure 12 relative to the squeeze out frame 11, Fig. 2 shows the right position thereof. The actuating lever 13 is directly coupled to the carrier structure 12. However, there may be a transmission between the actuating means 13 on the one hand and the carrier structure 12 on the other hand whereever this is appropriate. Of course, the complete structure may be motorized as well which would substantially improve the handing. However, a motorized system is difficult to apply with a trolley 1 as shown here.
Fig. 3 shows a schematic side view of the above.
An alternative of a carrier structure 12 that is movable sideways back and forth by means of a manual actuating means may be a continuous conveyor means guided by guide pulleys 14. This is shown as an embodiment of Fig. 4 in a side view, highly schematical. Here a manual crank drive 13' is coupled through a gear transmission 13" to the left guide pulley 14. The carrier structure 12 is constructed by two parallel running conveyor chains with rods as squeeze out formations 10 extending between those conveyor chains.
Above mentioned alternative construction allows for a continuous squeezing out of liquid from the flat mop cover 3. The driving means can be a manual crank drive with the actuating lever as shown, however a foot operated pedal drive as well as a motor drive is an appropriate means as well.
Fig. 1 and 2 show a squeeze out structure 8 on top of the first bucket 6. This squeeze out structure 8 defines a generally flat squeeze out surface 9 with a plurality of openings. As the mopping device has been removed in Fig. 2 the openings are clearly visible.
The squeeze out surface 9 is formed by a plurality of squeeze out formations 10.
The squeeze out formations 10 can be formed by a large part like a sieve, a grid, a perforated plate structure or the like. In the present embodiment the squeeze.
out formations 10 are formed by rods extending parallel to each other, the distance between the rods defining the openings of the squeeze out surface 9.
From prior art documents squeeze out formations 10 as rods, rolls, balls, or the like are known.
Now, as can be seen in Fig. 1 and 2, this first version of a squeezing out device according to the invention is characterized in that the squeeze out structure comprises a squeeze out frame 11 mounted in a fixed position relative to the bucket 6 for positioning the mop holder 4 of the mopping device, the squeeze out formations 10 are positioned within a separate carrier structure 12, the carrier structure 12 is movable relative to the squeeze out frame 11 so that the mop holder 4 with the flat mop cover 3 can remain stationary on the squeeze out surface 9 within the squeeze. out frame 11, whilst the squeeze out formations are moved relative to the mop cover 3. As already explained in the introductory part of the description, in this system the mop holder 4 can be pressed with constant and high pressure against the squeeze out surface 9. Nevertheless, an efficient relative movement between the squeeze out formations 10 and the mop cover 3 is realized, here by movement of the squeeze out formations 10 relative to the stationary mop cover 3 which is positioned within the squeeze out frame 11.
In the present embodiment it is provided that the carrier structure 12 is a frame that is movable back and forth, preferably sideways, by means of an actuating lever 13, pivotally mounted to the squeeze out structure 8 and/or the bucket 6 and/or the trolley 1.

However, there may be a transmission between the actuating means 13 on the one hand and the carrier structure 12 on the other hand whereever this is appropriate. Of course, the complete structure may be motorized as well which would substantially improve the handing. However, a motorized system is difficult to apply with a trolley 1 as shown here.
Fig. 3 shows a schematic side view of the above.
An alternative of a carrier structure 12 that is movable sideways back and forth by means of a manual actuating means may be a continuous conveyor means guided by guide pulleys 14. This is shown as an embodiment of Fig. 4 in a side view, highly schematical. Here a manual crank drive 13' is coupled through a gear transmission 13" to the left guide pulley 14. The carrier structure 12 is constructed by two parallel running conveyor chains with rods as squeeze out formations 10 extending between those conveyor chains.
Above mentioned alternative construction allows for a continuous squeezing out of liquid from the flat mop cover 3. The driving means can be a manual crank drive with the actuating lever as shown, however a foot operated pedal drive as well as a motor drive is an appropriate means as well.
