EP2868250B1 - Pressing attachment for a bucket of a wiping system and wiping system - Google Patents

Description

The invention relates to a pressing attachment for a bucket according to the preamble of claim 1 and wiper system with such a pressing attachment according to the preamble of claim 5.

A press attachment of this kind is from the US 1 767 385 A or even the US 502 448 A known. In both pressing attachments a cross-sectionally V-shaped funnel with liquid-permeable walls is provided, into which a wiper or a flap for squeezing the liquid can be pressed. The disadvantage of these systems in practice is that it is difficult to insert hinged panels with a fringe mop into the hopper. Such fringed mops are hinged around a point storage at the lower end of the stem in all directions, during the transfer of the pug on the funnel, the fringe holding plate must be rotated by 90 °, so that it can be lowered into the hopper. Only then will the fringes be squeezed between the plate and a funnel wall. Although the mop can be passed over the hopper so that the fringes abut the baffle wall formed by the front hopper wall with the upper scraping edge, but this leads only to a slight inclination of the plate, but not to a 90 ° rotation, so that the Plate subsequently backtracked. This is a comfortable insertion of the mop head but not possible.

Press attachments for buckets of wiper systems and wiper systems are also from the DE 102 10 569 A1 known. The known press attachments are used for pressing Used mop covers. These are attached to a hinged wiper on the outside, wherein the wiper has two juxtaposed and interconnected via a pivot axis plate wings that can be folded down to squeeze the mop cover so that the reference sags downwards in U-shape and in the funnel-like press attachment can be pressed, which in turn has openings on its underside for draining the pressed-out liquid. A similar press essay shows the EP 2 384 682 A2 , in which folded plate wings of a wiper are moved in the direction of the pressing attachment and then pressed with the broad side of the Ptattenflügel parallel to the direction of movement down into a compression shaft. Here, since the insertion funnel is further aligned with its longitudinal extension in the direction of movement of the mop head, a plate with hanging fringes can not be threaded in a movement of the free surface of the bucket on the presser head.

The latter known press attachments thus have the disadvantage that they can be used essentially only with folding flat wipers. In particular, in conjunction with a classic mop, which has a mop usually mounted rotatably mounted at the end of the handle and fringed at the bottom, round mop plate, the press attachment can be used only limited, since it is difficult to thread this fringe mop in the receiving shaft ,

The object of the invention is therefore to provide a press attachment for a wiper system, which is as well suited for threading and pressing a round fringed mop as a wiper head. A further object of the invention is to provide a wiper system with such a wiper device and a bucket, which is suitable with a press attachment for a round fringe mop.

This object is achieved according to the invention by a press attachment according to claim 1. With respect to the wiper system, the further object is achieved by a wiper system according to claim 5.

Due to the inventive design of the press attachment, it is now possible to use this also in connection with mop heads, which have a round mop plate with hanging down on the fringes. However, the invention is not limited to a fringe mop, any other mop plate can be used in conjunction with the press attachment according to the invention and the associated wiper system. In particular, the pressing attachment can also be designed so that it is able to accommodate conventional plate wipers.

The main advantage of the new press attachment is the suitability for a round mop plate of the mop head. When using the wiper device, the user will first clean a contaminated surface with the mop head located at the end of the handle, so that this in turn absorbs the dirt and must be rinsed and dried after a certain period of use. For this purpose, as in the prior art, the bucket of the wiper system is provided.

The bucket may have any shape, in practice, a substantially rectangular base of the bucket has proven to be particularly practical. This elongate shape has the advantage that on one side of the bucket the pressing area and on the other side the immersion area for immersing the wiper device can be provided. At the same time, the bucket can be kept smaller in size compared to a round bucket. Between the pressing area and the immersion area, a handle pivotally mounted about a pivot axis is usually provided, the center of gravity of the bucket lying on this pivot axis or at least in the vicinity of the pivot axis, so that the bucket does not tilt when lifted.

The mop head, which is initially immersed in the filled bucket in the immersion area, is moved back and forth so that dirt particles can be released from the cleaning surface. For the invention, it does not matter what this cleaning surface looks like, it can be used as well as a foam, the already mentioned fringed mop. Essential to the invention, however, is the suitability of the bucket and the press attachment for a fringe mop.

After rinsing out the dirt particles, the user raises the mop and transfers it above the opening of the bucket into the press area. There, the clean but still wet mop head is then partially dried to reduce the amount of liquid applied during the next wiping process. So that a round, disc-shaped mop head can be easily and simply inserted into the press attachment, according to the invention the geometry of the press attachment is designed such that the swiveling mop plate mounted on the end of the handle rotates approximately 90 ° when the mop head is inserted at an early stage, So set up vertically. The style of the wiper then runs almost parallel to the top of the mop plate. If the cleaning element or the cleaning pad on the underside of the mop plate is formed by drooping fringes, these hang then also almost parallel from the bottom of the mop plate on the side facing away from the style down.

So that the mop head is inclined, according to the invention the stripping edge is provided, which ensures that the fringes transmit a transverse force to the mop plate when the user pulls the mop over the stripping edge in the direction of the press attachment. If the user continues to lift the wiper out of the bucket so that the fringes do not come into contact with the wiper edge but are removed via it, the press attachment according to the invention can nevertheless be used, since then the wiping edge on the wiper head is lowered when the wiper head is lowered Bottom of the wiper head is supported and so the mop head obliquely sets when the contact point between the wiper head and the wiper edge outside the bearing of the stem and on the immersion region facing side of the mop head. Then the wiper edge will push the mop head upwards laterally and also tilt it.

Subsequently, the user can insert the mop in the press attachment, wherein the press attachment has a downwardly tapering lower portion, in which then the mop head is inserted with approximately vertical mop plate. The lower portion is formed so that even the insertion creates a pressing force on a side transformation of the lower portion, which serves as a pressing surface and at the same time is able to discharge the pronounced cleaning water into the bucket. For this purpose, the pressing surface may either be liquid-permeable, for example be formed as seven or have other passage openings. Alternatively, vertically extending elevations in the form of ribs or depressions in the form of beads in the pressing surface may also be provided so that the liquid on the side of the mop head can run down along the pressing surface. However, this embodiment will only be practicable if the cleaning element consists for example of foam and thus is not able to completely fill the depressions and thus clog them.

0ft one insertion of the mop head in the press attachment is not sufficient to achieve the desired pressing effect. In this case, the user can apply an additional force over the stem. The downwardly tapering lower region holds substantially the lower edge of the mop head fixed horizontally. At least one rear abutment surface of the press attachment forms an abutment that can be used to apply an additional pressing force over the post. The cleaning pad or the cleaning element and the mop plate is indeed arranged between the stem and the pressing surface, the user can further clamp the mop head by pivoting the handle in the direction of the pressing surface and thus additionally to squeeze. For this purpose, the lower edge of the mop head is supported at the lower end of the press attachment.

Alternatively, the user can also the stem in the opposite direction, ie in the direction of the rear contact surface, so that the style of the contact surface in the region of its upper edge is supported and thus also presses the mop head in the direction of the pressing surface.

The fringes possibly lying below the wiper head can be additionally pressed out by a vertical pressure force. After pressing out of the cleaning pad or the Einigungselementes this can then be removed from the press attachment and used again. Essential for the invention is the fact that the press attachment has a provided on its upper side with a rectangular opening immersion shaft for the folded mop head of the mop wiper designed as a floor wiper, said immersion shaft front serving at least in the lower part as a pressing surface wall and sides of the bucket end having the contact surface. The two surfaces are inclined to each other, so that this immersion shaft tapers downwards.

The lower region of the immersed shaft can be adapted to the shape of the mop head, so for example in a round mop plate also be rounded with a similar radius. The radius can be slightly larger, but not smaller than the diameter of the mop head. The contact surface and the pressing surface are preferably arranged parallel to the handle axis, thus extending transversely to the bucket from a bucket edge to the opposite edge.

The vertical insertion and subsequent extrusion in the horizontal direction has the particular advantage that the extrusion force is not applied exclusively in the vertical direction. Since a vertical force causes a tilting moment on the bucket, can be significantly reduced by dividing the necessary forces for pressing forces in a vertical and a horizontal component, the tilting moment, since a pressing in the horizontal direction in the worst case leads to the user shifts the bucket.

The press attachment can be firmly connected to the bucket edge, wherein in most cases a separate component will be preferred, resulting in a lower manufacturing costs and on the other that the bucket can also be used for other purposes. In the latter case, the pressing attachment, for example, has a cross-sectionally U-shaped edge, so that it can be plugged onto the edge of the bucket. Of course, all other employment opportunities are possible, the only essential is the fact that the shaft forming the active area in the bucket above the liquid level, but still held solvable.

Further features and advantages of the invention will become apparent from the subclaims and from the following description of preferred embodiments with reference to the drawings.

an alternative embodiment of the pressing attachment.

In FIG. 1 an inventive press attachment 2 is shown, which is placed on a bucket 1. The pressing region is here arranged from the left side of the rectangular bucket 1 shown in section, with the exception of the rounded corners. The bucket has a handle 7 shown in Figure two, which is mounted pivotably about a handle axis A in the middle of the bucket. The pressing region is virtually delimited from the immersion region by the vertical plane passing through the handle axis A. The press attachment 2 protrudes into the bucket 1 with a lower region, during which use of the wiper system so much liquid is filled into the bucket 1 that the press region is just not immersed in the liquid.

In FIG. 1 is a state of the wiper system shown by the user after rinsing the mop here designed as a mop head 8 lifts the wiper just out of the immersion area. In this case, the wiper device is at a height which is selected such that the round plate of the wiper head 8 is arranged slightly above the wiping edge 9. The fringes hang down from it.

The pressing attachment 2 has a baffle 10 on its side facing the immersion region. Now the user transfers the wiper device into the horizontal extrusion position, push the fringes of the mop head 8 against the baffle 10 and thus bring a tilting moment on the mop head 8. This tilting moment causes the mop head 8 to rotate counterclockwise, so that the left side of the round mop plate of the mop head 8 is automatically rotated in the direction of the dipping direction. The fringes then hang down on the then right side of the substantially vertical mop plate. The transfer of the mop head into the immersion position is in FIG. 2 shown, the corresponding insertion direction is marked here with E1.

Depending on the design of the cleaning pad or the cleaning element, the wiper edge can apply the above-mentioned force to the tilting moment on the rotatably mounted wiper plate of the mop head 8 apply. If, on the other hand, users had a slightly higher level of the wiper or if the fringes of the wiper head 8 were not heavy enough, for example, the tipping effect would not occur. This is expressed by the invention in that the contact surface 11 on the side facing away from the baffle 10 of the pressing attachment 2 is slightly higher than the baffle 10. This means that at the latest when reaching the immersion position of the left edge of the mop head 8 against the contact surface 11 encounters. This is angled in the upper part of something in the direction of the bucket center, so that they can turn the mop head eight then rotating down into the insertion shaft.

FIG. 3 shows the turning of the mop plate of the mop head 8 in the first pivoting direction S1. In this position, the wiper device can then be inserted in a second insertion direction E2 down into the immersion shaft of the press attachment 2. This is in FIG. 4 shown.

According to the invention, either the dangling coating of the wiper head 8 and the stripping of this coating on the scraping edge 9 or the abutment of the wiper head 8 on the rear contact surface 11 can be used to rotate the stem 5 of the wiper of the mounted mop head 8 in a vertical position To transfer mop plate. As in FIG. 5 1, the wiping head 8 (not visible in FIG. 5) inserted in the pressing attachment 2 can again be pressed against the pressing surface 6 by pivoting the handle 5 in a second pivoting direction S2. As in FIG. 1 shown, the pressing surface 6 is formed here as a sieve, so that the squeezed water can pass through them.

In FIG. 6 another embodiment of a press attachment 2 is shown, however, only slightly different from that in the Figures 1-5 different design described. In this embodiment, the baffle 10 is concave from the perspective of the first insertion direction E1, so that the two extending from bottom to top Outer edges are arranged closer to the plane passing through the handle axis A vertically compared to the central region. This comes has configuration leads to the fact that the fringes of the mob are guided in the transfer in the insertion shaft to the inside and at the same time already by the sliding of the fringes at the scraping edge 9 of these separated water is directed inwards and can not run on the bucket edge.
