Definitions
- the invention relates to a wringing device for a mop cover of a flat wiper with a handle, which comprises an essentially funnel-shaped wringing shaft with conically tapering towards the bottom, with counterpressing surfaces, in which the mop cover is partially detached from the mop plate when the mop plate is substantially vertical hanging downwards, can be inserted from above and can be pressed out by pressing the handle, the wiper plate being able to be pressed out at least partially into the wringing shaft, so that its downward end face forms a pressing surface.
- the invention further relates to the use of such a wringing device and a cleaning system which comprises such a wringing device. State of the art
- DE 196 20 633 C2 discloses a cleaning device with a flat wiper and a generic wringing device.
- the flat wiper has a handle and a wiper plate which is connected to the handle via a connecting element with a joint.
- a clamping device for fastening a wiping cover is arranged in the front area of the wiper plate as seen in the wiping direction.
- the mop cover is held by pressing the fabric down through the wiper plate.
- the flat wiper with wiper plate is lifted off the floor, the wiper plate folds down into a vertical position and the mop cover, which is only attached to the front edge of the wiper plate, sags vertically downwards.
- the mop cover is now inserted vertically from above into the wringing basket, which tapers conically downwards, whereby it folds.
- the mop cover is pressed out over the downward-facing end face of the wiper plate in the wringing basket.
- a disadvantage of the known cleaning device is that the mop cover must be placed very carefully when it is inserted into the wringing basket in order to achieve the desired folding. Parts of the mop cover that do not come into contact with the inner wall of the wringing chute, not below the contact surface, are not pressed out.
- the handle is in the most vertical position possible when pressure is exerted, so that the force exerted by the user is converted as effectively as possible into a squeezing force and is not directed against the side wall of the wringing shaft, which increases the risk of the tilting the wringing device-carrying container with cleaning liquid.
- Another disadvantage is that the mop cover is only held in the front area of the wiper plate in the working position. To prevent the To avoid wiping in the rear area, especially with high floor friction, the user must constantly exert a corresponding contact pressure on the handle while wiping.
- DE 40 11 713 A1 discloses a two-part wiper plate with plate wings pivotably mounted via folding axes, in which the plate wings can be folded vertically downwards for cleaning purposes.
- the mop cover is only attached to the ends of the panel wings and hangs down like a loop when the panel wings are folded down. In this position it can be immersed in a liquid bath and cleaned.
- the publication does not indicate whether or how the mop cover is pressed out after cleaning.
- the object of the invention is to develop a wringing device of the generic type in such a way that the mop cover is inevitably brought into the optimal position for the pressing out when it is introduced into the wringing shaft, without requiring special handling by the user or that there is a risk of tipping over Wringing device carrying container.
- Another object of the invention is to provide a cleaning system consisting of a flat wiper and a wringing device, in which the flat wiper and wringing device are matched to one another in such a way that wringing out can be carried out in a simple and efficient manner, but on the other hand the flat wiper can be adapted to the wringer is not impaired in its function.
- a wringing device for a flat wiper which comprises a downwardly conically tapering, essentially funnel-shaped wringing shaft with counterpressing surfaces, in which the wiper cover, when the wiper plate is in an essentially vertical position, is partially detached from it and hanging downward , can be inserted from above and can be pressed out by pressing the handle, the wiper plate for pressing out being at least partially insertable into the wringing shaft, so that its downward end face forms a pressing surface, devices for stabilizing the wiper plate against tilting during insertion and Squeezing provided in the wringing shaft.
- the mop cover and the wiper plate are automatically guided when they are inserted into the wringing shaft of the wring basket so that the mop cover is inevitably brought into a position that is favorable for wringing out and the force exerted by the user is optimally converted into a pressing force on the mop cover.
- lateral forces on the walls of the wringing shaft which could cause the container with cleaning liquid carrying the wringing device to tip, are avoided.
- the devices for stabilizing the wiper plate against tilting in a first plane comprise two mutually opposite first inner walls of the wringing shaft, the spacing of which is dimensioned such that the wiper plate is supported on both inner walls simultaneously when it is introduced into the wringing shaft ,
- first guide elements can be, for example, vertically extending, rib-like elevations on one of the inner walls or else on both inner walls.
- At least one of the two first inner walls additionally has second guide elements, on which corresponding counter-guide elements are supported on the wiper plate.
- the first guide elements can be designed such that they also take over the function of the second guide elements.
- the easiest way to do this is to design the guide elements as rib-like elevations on the first inner walls of the wringing shaft, which are positioned in such a way that they can be brought into engagement with the corresponding counter-guide elements on the wiper plate.
- the height of the wringing duct is advantageously dimensioned such that the lower ends of the wiper plate are already immersed in the upper region of the wringing duct and are in engagement with the devices for stabilizing the wiper plate against tilting when the wiper cover touches the bottom of the wringing device. This largely ensures that the force now to be exerted on the handle for compressing the mop cover in the wringing shaft is also not fully vertical Alignment of the handle cannot cause the wringer to tilt.
- the usual dimensions for such a wiper plate for the loop-shaped squeegee sagging result in a loop height of approx. 15 cm
- the height of the wringing shaft should therefore be greater than 15 cm. It has been found that an immersion depth of approximately 1 cm is sufficient for the lower ends of the wiper plate wings in order to achieve sufficient stabilization against tilting.
- the wringing shaft should therefore have a height of at least approximately 16 cm for this exemplary embodiment.
- the first inner walls are the walls opposite the top and bottom of the wiper plate brought into a vertical position. This means that the wiper plate is supported with its larger surfaces when it is inserted into the wringing shaft, and particularly secure guidance is achieved.
- a particularly efficient conversion of the force exerted by the user on the handle of the flat wiper into a contact pressure is achieved in that the wringing shaft is dimensioned such that the inner walls forming the guide surfaces and the arrangement of the guide elements in a vertical position about their longitudinal axis brought wiper plate are adjusted.
- the comparatively small end face pointing downward forms the contact surface.
- the contact surface is formed by the two end faces of the wiper plate wings folded down.
- the wiper plate folded down about its longitudinal axis and the contact surface is formed by the side surfaces of the wiper plate wings results in a factor 4 higher contact pressure.
- the insertion of the mop cover and the wiper plate into the wringing shaft is facilitated by the fact that the wringing shaft has an insertion funnel which widens upwards at its upper end.
- the wringing shaft has outlet openings in the lower area and in the shaft bottom. These can be groove-shaped openings, for example.
- the counterpressing surfaces in the wringing shaft can have raised areas to increase the contact pressure.
- the shaft floor is provided with rib-like elevations.
- the wringing device has means for attachment to a container for the cleaning liquid, for example a bucket. It is also advantageous if the wringing device additionally has means for holding the flat wiper in the container.
- a cleaning system comprises the wringing device according to the invention in combination with a flat wiper with a handle and a wiper plate with a detachably attachable wiping cover, the wiper plate being able to be brought into a substantially vertical position for pressing out the wiping cover and with the wiping cover partially loosened and sagging from above forth in the wringing shaft of the wringing device, its downward end face forming a pressing surface.
- the wringing device according to the invention can be used not only in combination with a flat wiper with a one-piece wiper plate, but also particularly advantageously for a flat wiper known per se of the type described in the introduction to the description, with a two-piece wiper plate with two plate wings that can be folded against one another and a wiper cover that connects to the outside facing ends of the plate wings can be detachably fastened, the plate wings being able to be folded down into a substantially vertical parallel position in a cleaning liquid for cleaning the mop cover, so that the mop cover sags downward in the form of a loop.
- the flat wiper is inserted from above into the wringing shaft of the wringing device in this position with the plate wings folded down and the wiping cover sagging downward in the form of a loop.
- the wringing device according to the invention can be used particularly advantageously for a flat wiper with a two-part wiper plate of the type described, which in addition to the foldable plate wings also has a central part which is firmly connected to the handle. Such a middle part can be formed on the side facing the surface to be cleaned as a functional surface with an additional cleaning function which can be actuated by exerting pressure on the handle.
- the functional surface is preferably designed as a “scrubbing surface” for loosening stubborn dirt and has a structuring for this purpose.
- the ratio between the raised areas formed by the structuring and the total surface of the wiper plate is advantageously between 1:10 and 1: 100 at a ratio of 1:50.
- the structured contact surface achieves approximately the same contact pressure on the surface to be cleaned as when using a scrubber.
- the structuring can, for example, take the form of ribs, which can be arranged vertically or at an angle to the wiping direction in order to create independence from the wiping direction.
- the ratio between the thickness of the wiping cover and the structure height should be between 2 and 1.
- the plate wings of the two-part wiper plate have supporting elements on their underside, which stabilize both plate wings in a folded-down parallel position against relative movement in the plane of the plate.
- Such support elements can be, for example, elevations on the underside of one plate part, which engage in corresponding depressions on the underside of the other plate part in the folded-down position.
- the plate wings can be locked in an aligned working position by means of a lock.
- Handling is particularly simple here if the locking takes place automatically when the panel wings are swung up into the working position and, for example, a lever which can be actuated by means of a foot is provided for releasing the locking.
- Locking devices with the described properties are known and have been described many times in the literature.
- the handle of the flat wiper can be connected to the wiper plate via a joint, preferably via a cardan joint.
- a joint for pressing out, it is advantageous if the joint can be at least partially locked, for example by means of ball thrust pieces.
- the mop cover whose shape corresponds approximately to the shape of the wiper plate, has a cleaning fabric on its underside. There are no restrictions with regard to the type or design of the cleaning tissue.
- the mop cover can be detachably fastened in the edge areas of the wiper plate, ie at the outer ends of the plate wings.
- the mop cover has so-called retaining tabs at its shorter ends, which overlap the outer ends of the plate wings in the edge region. These retaining tabs are placed around the outer ends of the plate wings and preferably by means of a Velcro fastener. Finally attached to the top of the panel wing in the edge area.
- other fastening options are also conceivable, such as push buttons.
- a cleaning system according to the invention comprises a container for holding the cleaning liquid, in the upper region of which the wringing device according to the invention can be fastened.
- holding means are also provided for parking the flat wiper in the container.

- FIG. 4 shows a front view of a cleaning system according to the invention, comprising a flat wiper with a wiper plate and a wringing device according to the invention.
- the wringing shaft 2 has an essentially funnel-shaped shape that tapers conically downwards. In the lower area are the counterpressing surfaces and outlet openings 3 for removing the cleaning liquid squeezed out of the mop cover. In the upper area of the wringing shaft 2, one can still see guide elements 4 a, on which corresponding counter-guide elements are supported on the wiper plate. At the top of the wringing shaft 1 there is an insertion funnel 5. This widens conically towards the top and serves as an insertion aid for the mop cover with wiper plate.
- Rectangular openings 6 are arranged on two opposite side surfaces of the insertion funnel 5, into which the two ends of a middle piece of the wiper plate of a flat wiper, which is firmly connected to the handle, engage when it is inserted into the wringing shaft 1.
- the distance between the side walls 7 a and 7 b of the wringing duct 1 is dimensioned in the present exemplary embodiment in such a way that the wiper plate is located when it is inserted into the wringing duct
- I is supported on both walls simultaneously and is thus stabilized against tilting in the direction of the side walls 7 a and 7 b. Tilting in a direction perpendicular to it is prevented by the guide elements 4 a in the wringing shaft 1 and the counter-guide elements 4 b on the wiper plate.
- the wringing device according to the invention from FIG. 1 is preferably used for a flat wiper, as shown in FIG. 2.
- the wiper head of such a flat wiper can be seen in FIG.
- the two-part wiper plate 10 consists of plate wings 10 a, 10 b which can be pivoted relative to one another about axes 18 a, 18 b, at the lower ends of which the retaining tabs 20 b of the wiper cover 20 are detachably fastened by means of a Velcro fastener.
