Description

Mop wringer and bucket combined with it

technical field

The present invention relates to a mop wringer, a mop handle holder for such a wringer, and a bucket combined with such a wringer.

Background technique

Mechanically assisted squeeze wringers of the joystick type are known. They typically consist of a basket, one or two pressure plates that slide into and out of said basket, a pivot rod operated by the user, and a closed transmission connecting the or each pressure plate to the pivot rod . As the pivot rod is pushed or pulled forward, the or each pressure plate moves into the basket, forcing the mop head with the mop material into the basket and causing the mop material to be wrung. As an example, Fig. 1 and GB2243537A show this device supported by a wheeled bucket.

In this prior art, the pivot rod is connected to a horizontally rotatable drive rod. To accommodate a conventionally shaped mop head as shown in Figure 2, the distal end of the pivot rod is connected to one of the inside drive rods adjacent to the wringer and is suitably offset from the center of the drive rod.

Other wringer arrangements also utilize a lever squeeze mechanism, eliminating the need for a drive rod by placing the lever on the outer surface of the wringer.

Neither of these offset arrangements is satisfactory. Due to the offset of the joystick, when the joystick is operated, a torsional moment is applied to the wringer, support bucket, wheel base and castors. This leads to premature wear and failure of the wringer and/or tub, thereby greatly reducing life expectancy.

Furthermore, the stability of the wringer and drum is reduced due to the transmission of torsional moments, which leads to a greater number of spills.

Also, conventional joysticks are typically offset to the right, which makes them difficult for left-handed users.

Finally, due to the conventional offset of the lever, when the mop head is placed in the wringer, the mop handle cannot be easily supported when it is desired to leave the mop unattended.

The present invention seeks to provide a solution to these problems.

Detailed ways

Referring to FIGS. 3 to 9 , there is shown a wheeled bucket 10 with castor wheels, and a joystick mechanically assisted mop wringer 12 removably placed on the upper edge of the bucket 10 . The combination of a bucket 10 and such a mop wringer 12 is known, for example, from GB2243537A and will therefore not be described in further detail.

However, for clarity, the mechanically assisted mop wringer 12 includes a perforated or generally mesh-type basket 14 that defines a channel 16 having a main opening 16a for receiving a mop head 18; two opposing Extrusion parts or pressing plate 20, they can move into or move out of basket 14 along guide groove 22, in order to push the mop material clamped by mop head 18 into the basket or on the basket 14; Closed transmission, the transmission Provided on one or both sides 24 of the mop wringer 12 for moving the platen 20 along the guide slot 22; a rotatable drive rod 26 which when rotated drives the or each transmission; and a long handle A joystick 28 is mounted to the drive rod 26 for rotating the drive rod 26 .

Mop heads 18 with a more slender and compact profile are now commonly used. As an example, Figure 4 shows such a mop head 18, and GB2262255A shows another mop head. These mop heads 18 have a threaded boss 30 for mounting a mop handle 32, and an elongated or circular clamping body 34 for typically stranded mop material (not shown).

Thus, as best shown in FIGS. 5 and 6 , the long handle lever 28 of the mop wringer 12 of the present invention is disposed or substantially disposed centrally on the drive rod 26 . This causes the lever 28 to travel or move in a plane 36 that bisects or substantially bisects the main opening 16 a of the basket 14 of the wringer 12 .

Preferably, the operating plane 36 of the joystick 28 in which its longitudinal axis 38 lies is slightly spaced or offset by 10 mm to 15 mm from the line 40 bisecting the opening 16a of the basket 14 and the drive rod 26 . However, it is feasible within a range of 0 mm (in other words, the joystick 28 is disposed at the middle position of the drive rod 26 ) and less than or equal to 20 mm.

Due to the reduced profile of modern compact mop heads 18, the influence on the wringer lever 28 which is arranged or substantially arranged in the middle position is eliminated or at least greatly reduced.

As shown in FIG. 3 and FIGS. 7-9 , the clamping member 42 is arranged on the joystick 28 and is used for clamping the mop handle 32 mounted on the mop head 18 easily and releasably. The clamp 42 is particularly suitable for a centralised lever 28 and has a generally waist pliers shape with a movable or integral hinge 44 . The profile of the clamping member 42 defines two clamping portions 46 , 48 . A clamping portion 46 from hinge 44 to waist 50 acts as a clamp for clamping clamp 42 to lever 28 . Threaded fastening means 52, such as screws and nuts or self-tapping screws, are provided at the waist 50 to fasten opposite sides of the clamp 42 together to secure the clamp 42 in place on the joystick 28 superior.

The other clamping portion 48 defines two opposing resilient jaws 54 between which the mop handle 32 can be inserted and clamped in a push-fit manner. The mop handle 32 is released from the jaws 54 of the grip 42 by simply pulling it away from the grip 42 .

The clamping element 42 can be arranged at any position along the longitudinal extension of the operating lever 28 .

Any suitable means for securing the clip 42 to the joystick 28 may be used. For example, the clamping portion 46 may be a push-fit latch located within the proximal end 58 of the lever 28 . In this case, the jaws 54 of the clip 42 extend transversely to the push-fit latch. However, this arrangement prevents the user from holding the joystick 28 firmly.

The securing means may also be a threaded fastener that directly secures the clamp 42 to the joystick 28 .

The mop handle clamp 42 can be used with any mop wringer setting or joystick in a substantially neutral position, whether the mop wringer is a mechanically assisted or transmission type mop wringer.

When the mop is placed in the basket 14 of the wringer 12 , the handle 32 of the mop may be held by the clamp 42 alongside the lever 28 of the wringer 12 . In this case, the mop can be supported reliably and without problems without external aids, such as leaning against a wall. Thus, the mop can be left unattended without risk.

The mop wringer joystick described above is primarily intended for a long-handled joystick which, in operation, extends beyond the front edge of the bucket in which the mop wringer is placed. However, a short handle lever, ie not extending beyond the front edge of the bucket, can also advantageously be arranged in the middle of the drive lever.

Mechanically assisted mop wringers may have only one extrusion.

"Mechanical assistance" to the wringer may take the form of a linkage located on one or each side of the wringer, replacing the transmission, or as an adjunct to the transmission, linking the lever and extrusion or each extrusion. pressed pieces.

By arranging the actuating lever of the wringer in or substantially in the middle position, undesired rotational and torsional moments transmitted to the wringer and the bucket are eliminated or greatly reduced. Thus, the forces applied by the user to the wringer and tub are evenly or more evenly distributed, thereby increasing the operational lifespan. In addition, left-handed users can more easily operate the wringer. The mop handle can be safely and securely supported by the center-positioned joystick, reducing the possibility of accidents.

The above-described embodiments are given by way of example only, and modifications obvious to a person skilled in the art do not depart from the scope of the invention as defined by the dependent claims.
