Description

The invention relates to a hinged wiper plate according to the preamble of claim 1 and a wiper device according to the preamble of claim 2.

Out EP 1 208 788 A1 is a wet mop for flat surfaces with two with the interposition of a double joint connected pressable mop plates known. The wet mop has a pivotally mounted on the double joint stem. For pressing the wiping plates against one another, a sliding sleeve arranged on the handle is provided with two pressure arms.

From the US 2 680 867 A For example, there is known a hinged wiper plate having plate wings interconnected by an articulated connection rotatable about a fixed axis. So that the mop cover is not pressed too much in the middle, the hinge is arranged on lateral flanges, which offset the axis of rotation down, however, require a comparatively thick mop cover in the form of a foam, so that the flanges do not mate with the floor during wiping Come in contact.

From the US 2,947,014A a wiper is known which comprises a hinged wiper plate with two wings according to the preamble of claim 1. Here, the wings are pivotable about a horizontally displaceable folding axis, so that the inner ends of the wings move apart during pressing. A similar solution shows the US 2,926,373 A. ,

Although these wipers relatively well avoid too much pressing of the inner regions or too little pressing of the outer regions of the mop cover, and thus provide an improved pressing result compared to the aforementioned solutions, the squeezing of the free ends of the mop cover is not optimal.

It is therefore an object of the present invention to provide a hinged wiper plate, with a better Auspressergebnis is achievable.

The object is achieved by a hinged wiper plate with the features of claim 1.

Another object of the invention is to provide a wiper device with such a hinged wiper plate. This object is achieved by a wiper device having the features of claim 2.

It has already been recognized in the prior art that the counter-folding of the plate wings is inhibited or made more difficult by the accumulation of material in the mop cover, which is increasingly folded with increasing folding position. With regard to the Auspressergebnisses this phenomenon leads to known foldable wiper plates to ensure that the arranged at the ends of the wiper plate parts of the mop cover are not sufficiently pressed and thus not sufficiently dried. In contrast, the foldable wiper plate according to the invention is designed such that, during the process of mutual folding of the plate wings, additional space in the region of the articulated connection, i. is created in the field of folding the mop cover. As a result, the mutual folding of the wiper plates is advantageously facilitated. In addition, this makes it possible to squeeze and dry the well arranged at the ends of the wiper plate parts of the mop cover sufficiently well.

According to the invention, the folding wiper plate is now configured such that the first plate wing and the second plate wing, the squeegee auspressend over a parallel position against each other are hinged.

The foldable wiper plate according to the invention has the enormous advantage that a much better drying result is achieved, so that the maintenance of liquid-sensitive floors, such as parquet, is possible.

The first plate wing and the second plate wing are arranged relative to each other displaceable. For this purpose, it can be provided, for example, that the first plate leaf and / or the second plate leaf or parts of the first plate leaf or parts of the second plate leaf are each arranged displaceably in a linear guide. The plate wings are still in the area of the articulated connection in the Gegeneinandklappen the both plates wing auseinenderdrückbar. Advantageously, the folding wiper plate can be designed such that the mop cover presses the plate wings apart in the region of the articulated connection when the two plate wings are folded against each other - in particular due to the accumulation of material occurring during folding.

In a particularly advantageous embodiment, the first plate wing is arranged rotatable and / or pivotable about a first axis, wherein the first axis is arranged displaceable relative to the second plate wing. In particular, it can be provided that the second plate wing is turnable / or pivotable about a second axis different from the first axis.

In one embodiment, which allows a particularly good extrusion result, at least the first axis is arranged displaceable relative to the second axis. It can be provided, for example, that both the first axis and the second axis - for example, relative to a common holding element - are arranged displaceably. Preferably, the first and / or the second axis are arranged displaceable perpendicular to its longitudinal extent.

The foldable wiper plate according to the invention can be used in wiper devices of all kinds, for example floor wipers, window wipers, motor vehicle wipers or furniture wiping devices - to name only a few examples.

In the drawing, the subject invention is shown schematically and will be described below with reference to the figures, wherein like-acting elements are provided with the same reference numerals. Showing:

FIG. 1 shows a hinged wiper plate 1, on which a handle 3 is fixed, according to the prior art in the wiping position (unfolded). A first plate wing 5 is arranged with the rotation axis 7 hinged to a holding element 9. Also on the holding element 9, a second plate wing 13 is arranged with the second axis 11. The first plate wing 5 and the second plate wing 13 together carry a mop cover 15, which is designed as a sponge. After a first wiping the mop cover is swung together with the folding wiper plate 1 in a bucket filled with liquid and must then be dried.

FIG. 2 shows the wiper according to the prior art in the pressing. With the aid of a press fork 17, which is pushed over the folding wiper plate 1, the first plate wing 5 and the second plate wing 13 are pivoted toward each other. In the area of the articulated connection, the material of the mop cover folding there folds up and brakes the squeezing movement of the plate wings 5, 13 and the press fork continuously. As a result, the pushing of the presser fork 17 on the plate wings 5, 13 increasingly difficult. This leads in the last consequence to the fact that the parts of the mop cover, which are arranged at the free ends of the first plate wing 5 and the second plate wing 13, can not or only insufficiently pressed.

FIG. 3 shows a foldable wiper plate according to the invention in the wiping position (unfolded). The foldable wiper plate 1 according to the invention has a first plate wing 5 and a second plate wing 13. Both the first plate wing 5 and the second Plate wings 13 are hinged to a common support member 9. The articulated connection between the first plate wing 5 and the common holding element 9 is realized by means of a first axis 7, which is guided in a first slot guide 21. The articulated connection of the second plate wing 13 with the common holding element 9, via a second axis 11, which is guided in a second slot guide 23, realized. By the slot guide bearing the first axis and the second axis, the first plate wing 5 and the second plate wing 13 are arranged relative to each other displaceable. It is a spring element 25, which is designed as a spiral spring 27 is provided to hold the plate wings 5, 13 by means of the spring force in the wiping position or to transfer the plate wings 5, 13 after completion of the Auspressvorgangs back to the wiping position. The coil spring is designed as a tension spring and secured by means of retaining bolts 29 each having one end to each one of the plate wings 5 and 13.

FIG. 4 shows the foldable wiper plate 19 according to the invention during the Auspressvorgangs using the presser fork 31. When pushing the presser fork 31 on the plate wings 5, 13, the first axis 7 and the second axis 11 in their slot guides 21, 23 in the common holding element 9 move outward towards the press fork tines. As a result, the distance of the plate wings 5, 13 is increased in the region of the articulated connection, so that there is no material accumulation of the mop cover 15. This advantageously achieves that the press fork 31 can be easily pushed over the plate wings 5, 13 and not only up to a V position, but even to the parallel position of the plate wings 5, 13 and beyond as it is in FIG. 5 is shown, the coil spring 27 is in FIG. 4 indicated only by a line.

FIG. 5 shows the foldable wiper plate 1 according to the invention in the end position of the Auspressvorganges. In this position, the first axis 7 and the second axis 11 are each pressed in their slot guides 21, 23 of the folded mop cover 15 against the force of the coil spring 27 completely outwards. The press fork 31 is, as can be clearly seen, designed in such a way that the distance between the fork tines and the fork tine ends down, so that a folding of the plate wings 5, 13 is made possible beyond the parallel position addition. It can be clearly seen that the foldable wiper plate 1 according to the invention also makes it possible to sufficiently squeeze out the parts of the mop cover 15 which are at the free ends of the plate wings 5, 13.
