Definitions

  • the invention relates to a wiper with a handle and arranged at the lower end of the handle wiper device with a wiper plate and a wiper pad and a slidably mounted in the longitudinal direction of the handle sliding sleeve with a squeezing device, which can be brought by moving the sliding sleeve of a wiper position in a Auspresswolf wherein the mop plate comprises two pivotally mounted mop plate wings, which are collapsible by pressing the ejection device into the Auspresswolf and pressed against each other.
  • a wiper of the type mentioned is, for example, from the EP 1 208 788 A1 known.
  • the known wiper has a handle and a slidably mounted on the handle in its longitudinal direction sliding sleeve. At least two pressing arms project from the sliding sleeve in the direction of a wiper device arranged at the lower end of the handle, the wiper device having a wiper plate with two wiping plate wings pivotably mounted between a wiping position and a wringing position with a wiper pad.
  • the press arms slide over the mop plate wings and press them against each other to wring out the wiping pad therebetween.
  • grooves are provided on the inner surfaces of the press arms according to the document as guide means, engage in the associated elevations on the mop plate wings.
  • a disadvantage of the known wiper is, on the one hand, that the pressing arms, in order to withstand the counterforce by the counter blades pressed against the wiping plates, must be mechanically very stable. This requires a higher cost of materials. On the other hand cause the above-described guide devices still additional manufacturing costs.
  • the object of the invention is to develop a wiper of the known type so that it is easier and less expensive to produce and has advantages in terms of manageability.
  • the wiper according to the invention has a handle and a wiper device arranged at the lower end of the handle with a wiper plate and a wiper pad as well as a sliding sleeve slidably mounted in the longitudinal direction thereof with a squeezing device.
  • the squeezing device can be brought from a wiping position into an expressing position by displacing the sliding sleeve.
  • the mop plate has two pivotally mounted mop plate wings, which can be folded by moving the squeezing in the Auspress too and are pressed against each other.
  • the ejection device is designed as an ejection housing which has side surfaces and an opening facing the wiper device through which the folded-together wiper plate vanes are at least partially insertable into the ejection housing.
  • the cross-sectional area of the extrusion housing corresponds, according to a preferred embodiment of the invention, to the cross-sectional area of the folded wiper plate wings or, in order to increase the extrusion pressure, is slightly smaller than the latter.
  • the squeeze housing in the preferred embodiment described above for a wiper is in the shape of a flattened body having two wide (aligned parallel to the surfaces of the folded squeegee blades) and two narrow side surfaces (perpendicular to the surfaces of the folded squeegee blades).
  • the wiper according to the invention is simple and inexpensive to produce. Due to the fact that the extrusion housing surrounds the wiper in its extrusion position on all sides, the wiper plate is automatically aligned when it is drawn into the extrusion housing, regardless of the angular position in which the wiper plate impinges on the opening. The use of guide elements, as provided in the above-described prior art, is therefore not required.
  • the Auspressgeophuse can be visually designed very appealing, are provided spielspielmik for loosening the overall picture with recesses at appropriate locations.
  • Such recesses have the other Advantage that they not only lead to a saving of material and thus also to a lower weight, but also create access to otherwise difficult to clean surfaces.
  • press rollers are provided on the pressing surfaces of the Auspressspalts. This reduces the friction during insertion of the wiper device in the Auspressspalt.
  • the press rollers are mounted according to a further preferred embodiment of the invention in oblong holes, wherein the distance between two oppositely arranged oblong holes tapers towards the top.
  • An introduced into the Auspressspalt wiper device takes due to the frictional forces the pressure rollers with upwards, which is due to the conical orientation of the slots, the distance between the oppositely disposed press rollers and thus the width of the Auspressspalts increasingly reduced. This has the advantage that the extrusion pressure during insertion of the wiper device to the lower end of the plate wings is successively increased, whereby a better Auswringwort is achieved.
  • means may be provided which cause a 90 ° rotation of the extrusion housing in each case when pushing back and forth between the expression and the wiping position.
  • the Auspressgeophuse is aligned with its largest longitudinal extent, namely the wider side surfaces whose width corresponds at least to the width of a plate wing, in the wiping direction. This may interfere with wiping under cabinets or the like, if the stem of the wiper is to be guided at a very shallow angle to the surface of the soil to be cleaned. Perpendicular to the length expansion can be kept much lower, since the distance between the press rollers may not be greater than the thickness of the two folded mop plate wings. This distance corresponds to the width of the narrower side surfaces.
  • the wiper plate blade tops can be provided with a material with reduced sliding friction, for example with a coating of PTFE or POM.
  • ramps for generating a pressure profile analogous to the above-described arrangement of the elongated holes, in which the press rollers are mounted can be provided on the wiper plate wing back. Such ramps also cause an increase in the pressure on the mop plate wings during insertion of the wiper device in the Auspressspalt.
  • a particularly simple handling during cleaning with a wiper according to the invention is ensured if the wiper device is articulated on the end of the handle.
  • a universal joint is used here.
  • the advantageous for wiping lateral pivoting movements are thus easily possible.
  • a center piece is provided for articulated connection between the wiper device and the handle, on which also the mop plate wings are pivotally mounted against each other.
  • the Auspressgepuse can be designed at its lower end so that it serves as a base for the wiper.
  • wiping pads there are no restrictions with regard to the wiping pads to be used. All wiping pads suitable for wipers with wiping plates with folding squeegee blades and / or commonly used may be used. Also mounting options for such wiping pads on the mop plate are well known in the art and will not be further explained at this point.
  • a layer of a soft material such as foam, in particular closed-cell foam, soft rubber or the like, be provided as a pad for the wiper pad, this layer is advantageously permanently attached to the mop plate.
  • the wiper pad can be made much simpler in this embodiment and thus manufactured more cost-effectively.
  • this layer which does not usually wear quickly, is not retained and, as in the case of the wiper pad laminates known from the prior art, in which such a layer is usually integrated, is not disposed of. This also results in a cost advantage.
  • this solution is advantageous in environmental terms.
  • the wiper according to the invention is preferably made of materials which are insensitive to corresponding liquids for cleaning a floor, such as for example Kunsstoffmaterialien. Certain parts of the wiper, which must be mechanically stable, but can also be made of metal.
  • the procedure was as follows: A water-saturated wiper pad was attached to the mop plates of the two wipers and by pressing the sliding sleeve with a conventional effort (corresponds, as determined by a series of tests, an extrusion pressure of about 80 N ) squeezed out. Subsequently, the wiping pads were weighed and re-attached to the mop plates. In a next step, a test floor area of 5 m 2 was wiped with the wipers with the wiping pads, and the wiping pads were weighed again. From the difference between the results of both weighing processes, the weight of the water delivered by the two wiping pads to the test soil surface during wiping was determined.
  • the standard wiper resulted in a water quantity of about 7.6 g / m 2.
  • the amount of water discharged to the bottom was much lower at only 3.3 g / m 2 .
  • the wiper according to the invention thus, it can be easily used to clean delicate floors such as parquet, wood or marble floors.
  • a wiper 1 according to the invention with a stem 2 and arranged at the lower end of the stem 2 wiper device 3 with a mop plate 4 and arranged on the plate bottom wiper pad 4.1 and a slidably mounted on the handle 2 in its longitudinal direction sliding sleeve 5 with a squeezing device, which is formed according to the invention as Auspressgephinuses 6 with side surfaces and one of the wiper device 3 facing opening 7.
  • the Auspressgecher can be brought by moving the sliding sleeve 5 from a wiping position in a Auspress ein.
  • the mop plate 4 has two pivotally mounted mop plate wings 4.2, 4.2, which are at least partially inserted into the Auspressgephaseuse 6 through the opening 7 by moving the Auspressgeophuses 6 in the Auspresswolf from below.
  • the mop plate wings 4.2, 4.2 as below in particular with reference to Fig. 10 will be explained in more detail, aligned, collapsed and pressed against each other to squeeze out the wiper pads located therebetween.
  • the extrusion housing has, in accordance with the cross-sectional area of the folded-together wiper blade wings, in each case two narrow sections 6.1, 6.1 or wide side surfaces 6.2, 6.2 opposite one another.
  • the wider rare areas 6.2, 6.2 are formed as closed wide webs. From its lower end protrudes in each case a fork-shaped holder 6.3 for supporting each one Auspressrolle 8 obliquely to the outside.
  • the narrower side surfaces 6.1, 6.1 are open, so that all parts of the wiper 1, for example, are easily accessible for cleaning. Furthermore, the partially open structure not only achieves a material saving, the visual impression also wins.
  • Auspressrollen 8 is not mandatory, as could the lower edges of the side walls 6.2 themselves serve as pressing surfaces for the mop plate wings. However, the effort required to move the sliding sleeve 5 is considerably reduced by the reduced friction when using Auspressrollen 8.
  • the force is further reduced by the fact that the press rollers 8 exert pressure over the entire width of the squeegee blades in a line-shaped area on the squeegee blades 4.2, 4.2, and not only in a nearly punctiform area as in the case of the known press arms.
  • the wiper device has a center piece 4.3, on which the wiper plate wings 4.2, 4.2 are pivotably mounted. With this center piece 4.3, the lower end of the stem 2 is connected via a universal joint 9.
  • the opposing fork-shaped brackets 6.3 for the Auspressrollen 8 are connected to each other by transverse webs 6.4 and fixed in their distance from each other.
  • the Auspressrollen 8 and the transverse webs 6.4 limit according to a preferred embodiment of the invention, a Auspresspalt, through which the wiper device 3 for pressing the wiping pad 4.1 is at least partially passed with folded Wischplattenhoffln 4.2, 4.2.
  • the fact that the distance between the press rollers 8 is fixed by the transverse webs 6.4, it can lead to any widening of the press nip and thus to a reduction of the exerted by the squeezing on the mop plate wings 4.2, 4.2 pressure.
  • an inventive wiper on an integrated Renistsmittel disposer with spray and associated actuating means is illustrated in the figures.
  • a spray nozzle 10 can be seen in the region of the open side surfaces 6.1.
  • FIGS. 2 and 3 show for the in Fig. 1 illustrated wiper 1 in an enlarged detail view of the sliding sleeve 5 with extrusion housing 6 in the Auspress ein with folded and inserted into the extrusion housing 6 mop plate wings 4.2, 4.2.

  • the in the FIGS. 4 to 6 shown wiper 1 is characterized in that the extrusion housing 6 has the shape of a downwardly open flattened bell.
  • the housing wall is substantially closed except for two narrow slot-shaped recesses in the narrow side surfaces 6.1, 6.1 of the extrusion housing. Through the lower edges of the wall of the Auspressspalt is bounded.
  • This embodiment has the advantage, inter alia, that the extrusion housing in the wringing position can be used as a stand for the wiper.
  • the wider side surfaces 6.2 are completely open, while the narrower side surfaces have 6.1 narrow gap-shaped recesses.
  • FIGS. 10a) - d) show a further preferred embodiment of a wiper according to the invention 1.
  • the Auspressgeophuse 6 is shorter compared to the Auspressgephaseusen in the embodiments described above. While in the wipers 1 described above, the length of the Auspressgeophuse 6 is selected in each case so that it encloses the above the wiper plate 4 angordnete on the stem 2 spray nozzle 10, which sees in the FIGS. 10 a) - d) illustrated embodiment between the extrusion housing 6 and the sliding sleeve 5 before a further sleeve section 5.1, which has an elongated slot 5.2 in the region of the spray nozzle 10.
  • the height of the extrusion housing 6 only corresponds approximately to the length of one Wiper plate wing 4.2, so that the folded wiper plate wings 4.2, 4.2 are just completely inserted.
  • the narrow side surfaces 6.1, 6.1 are formed as webs, while the wide side surfaces 6.2, 6.2 are open. At the lower ends of the webs holders for supporting the press rollers 8 are provided on both sides. The press rollers 8 limit the side surfaces 6.2, 6.2 downwards.
  • FIG. 10 a) - d) is shown how a at an angle to the formed as a press nip opening 7 wiping plate 4 with folded Wischplattenulatein 4.2, 4.2 automatically aligns at the opening 7 without any guidance devices in the correct position and further Actuation of the sliding sleeve 5 immersed in this.
  • FIGS. 11 a) - d) show a schematic representation of the wiper from the FIG. 10 (The reference numerals have been omitted for clarity) the advantageous effect of a 90 ° rotation of the extrusion housing in the transition from the Auspress ein in the wiper position. It can be seen that the Auspressgeophuse is aligned in the wiping position with its wider side surface perpendicular to the wiping direction, whereby the freedom of movement is substantially increased in the operation of the stem.
