Description

  The present invention relates to a mop squeezing device, a mop handle holding member for such a squeezing device, and a combination of such a squeezing device and a bucket.

  Mechanically assisted pressure squeezing devices operated by levers are well known. They typically include a basket, one or two pressure plates slidable in and out of the basket, a rotatable lever operable by the user, and a lever connected to one or each pressure plate. And an extended gear mechanism. When the lever is pushed or pulled forward, one or each pressing plate moves into the basket, pushing a mop head with mop material into the basket and the mop material is squeezed. Such an arrangement supported by a wheeled bucket is shown, for example, by FIG. 1 and British Patent Publication GB 2243537A.

  In this prior art, the lever is connected to a drive bar that is rotatable in the horizontal direction. In order to accommodate the conventional shape of the mop head as shown in FIG. 2, the distal end of the lever is connected to a drive bar adjacent to one inside of the throttling device, and is sufficient from the center of the drive bar. Is offset.

  Another arrangement of the diaphragm device that can also utilize a pressing mechanism operated by a lever eliminates the drive bar by arranging a lever on the outer surface of the diaphragm device.

  Both of these offset placements are inadequate. Because of the offset lever, when the lever is operated, a torsional moment is applied to the throttling device on the throttling device that supports the bucket, wheelbase and castor. For this reason, the throttle device is quickly worn out and broken, and / or the average life is considerably shortened.

  Also, since a torsional moment is applied, the stability of the throttling device and the bucket is reduced and spills in large quantities.

  Furthermore, typically, conventional levers are offset to the right, making it difficult for left-handed users to use.

  Finally, because of the conventional offset lever, the mop handle is easily supported when the mop head is placed in the iris and it is preferable to leave the mop unsupported. I can't.

  The present invention seeks to solve these problems.

  According to a first aspect of the present invention, in a mop squeezing device, a basket having an opening for receiving a mop head having mop material to be squeezed, and for pushing the mop material of the mop head into or against the basket. A lever-operated mechanically assisted pressing mechanism including a pressing member and an extending lever for operating the pressing member are arranged in a plane that divides or roughly bisects the opening of the basket. A mop squeezing device is provided.

  According to a second aspect of the present invention, there is provided a holding member for the lever of the mop squeezing device according to the first feature of the present invention, the means for fixing the holding member to the lever of the squeezing device, There is provided a holding member having a grip part for detachably holding the mop handle.

  According to a third aspect of the invention, there is provided a combination of a mop squeezing device and a bucket according to the first feature of the invention, wherein the mop squeezing device is removably attached to the bucket.

  Hereinafter, the present invention will be described in more detail by way of example with reference to the accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION

  Referring to FIGS. 3-9, there is shown a wheeled bucket 10 having a castor and a mechanically assisted mop squeezing device that is detachably provided on the upper rim of the bucket 10 and operated by a lever. ing. The combination of the bucket 10 and such a mop squeezing device 12 is generally known, for example, from British Patent Publication 2243537A, and need not be described in further detail.

  However, for clarity, the mechanically assisted mop squeezing device 12 has a main opening 16a for receiving the mop head 18 and has a holed or generally lattice type basket that defines the channel 16. 14 and two opposing pressures movable along guide slot 22 in and out of basket 14 to move the mop material held by mop head 18 into or out of basket 14. Section or pressing plate 20, a closed gear mechanism provided on one or both sides 24 of the mop squeezing device 12 for moving the pressing plate 20 along the guide slot 22, and one or each gear when rotating. A rotatable drive bar 26 for driving the mechanism, and a drive bar attached to the drive bar 26 And a long handle lever 28 for rotating the motor 26.

  Currently, a mop head 18 having a fairly slim and compact outer shape is used as a basis. For example, such a mop head 18 is shown in FIG. 4 and a different type of mop head is shown in British Patent Publication 2262255A. These mop heads 18 are threaded protrusions 30 for attaching a mop handle 32 and an extended or circular grip for attaching typically made mop material (not shown). And a main body 34.

  As best shown in FIGS. 5 and 6, as a result, the long handle lever 28 of the mop squeezing device 12 of the present invention is located at the center or substantially the center of the drive bar 26. For this reason, the lever 28 operates or moves in a plane 36 that bisects or approximately bisects the main opening 16a of the basket 14 of the expansion device 12.

  The plane 36 on which the lever 28 is actuated, with the long axis 38 of the lever 28, is offset by a space from the line 40 that bisects the opening 16a of the basket 14 and the drive bar 26 from 10 mm to 15 mm. However, the range can be from 0 mm (that is, the lever 28 is located at the center of the drive bar 26) to 20 mm or less.

  According to the small profile of current compact mop heads, the lever 28 that performs the diaphragm operation is not disturbed or at least considerably reduced in the middle or substantially in the middle.

  As shown in FIGS. 3 and 7 to 9, the holding member 42 is provided on the lever 28 in order to detachably hold the mop handle 32 attached to the mop head 18. The retaining member 42 is used in particular for the central lever 28 and has a generally central constricted scissor shape with a hinge 44 that is living or integral. The shape of the holding member 42 defines two grip portions 46 and 48. One grip 46 from the hinge 44 to the waist 50 acts as a clamp for stopping the holding member 42 on the lever 28. A threaded fastening device 52, such as a bolt and nut or a self-tapping screw, is positioned on the waist 50 to secure the opposing sides of the retaining member 42 together, thereby allowing the lever 28 to be in place at the appropriate location. The holding member 42 is fixed to.

  The other grip part 48 defines two flexible opposing jaw parts 54, and the mop handle 32 is pushed between the jaw parts 54 so as to be inserted and gripped. The mop handle 32 can be simply detached from the jaw 54 of the holding member 42 by being pulled out of the holding member 42.

  The holding member 42 can be disposed at any position along the longitudinal range of the lever 28.

  Any suitable means that can secure the retaining member 42 to the lever 28 can be used. For example, the grip portion 46 may be a push plug disposed within the proximal end 58 of the lever 28. In this case, the jaw 54 of the holding member 42 extends laterally to the push plug. However, this arrangement may be a hindrance for the user holding the lever 28.

  The fixing means is also a fastener that is threaded to directly fix the holding member 42 to the lever 28.

  The mop handle holding the holding member 42 is a lever of any mop squeezing device in the middle or substantially in the middle, regardless of whether the mop squeezing device is mechanically assisted or a gear type mop squeezing device. Can be used together.

  The mop handle 32 can be held along the lever 28 of the squeezing device 12 by the retaining member 42 when the mop is positioned in the basket 14 of the squeezing device 12. Under this condition, the mop is securely and positively supported without the need for external assistance to be supported by the wall. For this reason, the mop can be left without danger.

  The lever of the mop squeezing device described above is intended primarily as a long handle lever, and when operated, extends beyond the front end of the bucket where the mop squeezing device is located. However, a short handle lever, ie a lever that does not extend beyond the front end of the bucket, is also preferably located in the middle of the drive bar.

  A mechanically assisted mop squeezing device can have only one pressing member.

  The 'mechanical assistance' of the throttle device forms a coupling arrangement on one side or each side of the throttle device that connects the lever and one or each pressing member instead of or in addition to the gear mechanism. be able to.

  By arranging the lever of the throttle device in the center or substantially in the center, undesirable rotational and torsional moments applied to the throttle device and the bucket can be eliminated or considerably reduced. For this reason, the force applied to the throttle device and the bucket by the user is evenly or more evenly distributed, and the operating function life can be extended. Furthermore, a left-handed user can operate the diaphragm device more easily. The mop handle can be safely and securely supported by a central lever.

  The embodiments described above are given by way of illustration only and modifications will be apparent to those skilled in the art without departing from the scope of the invention as defined by the appended claims.
