Finally is out of the DE 10 2018 112 821 A1 known with interlocking panel wings and a release option via a foot pedal. The EP 3 785 595 A1 again shows a similar wiping plate, although here the force for releasing the locked wiping plates is generated via spontaneous braking of the wiping device after a downward movement.
  • a wiping plate having the features of claim 1 .
  • the wiper plate according to the invention has in particular an elastically deformable area which interacts with the latching means and which is deformed by the release device when the actuating means are actuated, the latching edge and the retaining latch being disengaged as a result of the deformation.
  • the release device is formed here by an actuating means that the user can operate with his foot or with his hand. As with the known mop plates described above, this actuating means is preferably a foot pedal.
  • the latching means are formed by at least one holding latch and a latching edge corresponding thereto. It is therefore a form-fitting engagement of the locking edge by the retaining catch.
  • several pairs of retaining catches and locking edges can also be provided, or multiple retaining catches can also engage behind a common locking edge or, alternatively, a retaining catch can engage multiple locking edges.
  • these forces are not particularly large in the case of the usual wiping plates, since the latching means are only intended to prevent the plate wings of the wiping plate from unintentionally folding down when the wiping device is lifted.
  • the snap-in connection must therefore essentially be able to hold the weight of the panel wings and the damp wiper covering hanging from them.
  • the locking means are preferably designed in such a way that the loading of the wiping plate in the position of use or the transfer of the plate wings into the position of use by the user triggers an automatic locking.
  • the retaining latch engages behind the latching edge.
  • the wiping plate is preferably designed in such a way that the locking connection engages at the latest when the wiping plate is loaded by the user.
  • the release device is provided in order to be able to fold down the plate wings when lifting the wiping plate for squeezing out, spinning out or changing the wiping covering.
  • the latching means Preferably, only one of the two panel wings, which is referred to in connection with the description of the present invention as “fixable panel wings”, is held by the latching means. This is sufficient to implement the function of the wiping plate, since either the other plate wing, referred to in connection with this invention as a “passive plate wing", can be fixed if there is a second plate wing or, if it can also be pivoted, via the fixable plate wing can be held. This is done, for example, via a panel lock formed by a blocking portion.
  • the blocking section is arranged on the passive panel wing and is covered by an area of the fixable panel wing in the position of use.
  • the The blocking section is arranged in such a way that it has to be pivoted upwards when the passive panel wing is folded down. Since this is only possible when the covering area of the fixable panel wing releases the movement of the blocking section by folding down the fixable panel wing, the passive panel wing is held in position until it is released.
  • the blocking section will preferably protrude beyond the pivot axis of the passive panel wing when viewed from the outer end of the passive panel wing, so that it is automatically moved upwards when pivoting.
  • This blocking section which protrudes beyond the pivot axis, can also be incorporated into the inner end of the panel wing, into which a bolt, about which the panel wing can be pivoted, is inserted.
  • the elastically deformable component can be both the fixable plate wing and preferably the joint adapter or a part thereof, also an add-on part.
  • the invention is described below using a deformable joint adapter.
  • the elastically deformable area can also be provided on the fixable panel wing.
  • the only essential feature is the fact that the actuating means deforms this elastically deformable area and that one of the two parts of the snap-in connection is arranged in this area and is designed in such a way that the deformation means that the form-fitting grip of the snap-in edge under the retaining catch is eliminated .
  • the articulated adapter is a central middle piece of the wiping plate. One or two axes are mounted on this, via which the panel wings are articulated in a pivotable manner on the joint adapter. Furthermore, the articulated adapter usually has a handle receptacle via which a handle of the mopping device can be connected to the mopping plate.
  • This joint adapter which is designed, for example, in the form of a small, boat-like or cuboid body, is now additionally used according to the invention to provide an easily detachable latching device.
  • the end of the joint adapter facing the fixable plate wing is the elastic area and carries the retaining catch.
  • the corresponding side wall of the articulated adapter can be provided with two vertical and one horizontal, lower gap, which works out a spring tongue connected in the upper area to the remaining wall parts of the articulated adapter from the wall of the articulated adapter.
  • the retaining latch protrudes like a lip or nose in the direction of the panel wing that can be fixed. The latching edge arranged on the fixable panel wing in turn engages behind this protruding area of the retaining latch.
  • the retaining latch can also be provided on the fixable plate wing, which then engages behind a latching edge on the wall of the articulated adapter or engages in a window in the wall of the articulated adapter.
  • the actuating means which is designed in particular as a foot pedal.
  • the actuating means has a protruding pressure area, which is moved against the elastic area during an actuation movement of the actuating means, for example when the above-mentioned foot pedal is depressed, and then subsequently deforms it in a pressing manner.
  • Displacement of a part that is displaceably mounted on the joint adapter can of course also be considered here.
  • the actuation means is movably mounted on the fixable plate wing in such a way that the actuation inevitably results in the employment of the elastic area.
  • the spring tongue described above is not the only way of realizing the elastic area.
  • the retaining latch itself can be mounted so that it can be displaced and pressed in against an elastic force.
  • the entire joint adapter can be deformable.
  • the plate wing that can be fixed is mounted on the articulated adapter so that it can be displaced in the transverse direction against a spring force.
  • the elastic area would therefore be the mounting of the panel wing, with the actuation means pressing the fixable panel wing outwards a little, as a result of which the latching means disengage.
  • a further latching possibility is provided for the actuating means by the deformation of the elastically deformable region, in which the spatial Spacing of the locking means can be kept while releasing the pivotability of the fixable plate wing.
  • This possibility is a particularly positive effect of the solution according to the invention.
  • the actuating means can engage after a first movement phase, during which the pressure area for releasing the locking means has pressed in the elastically deformable or displaceably mounted area, while maintaining this deformation. In this position of the actuating means, the retaining latch is spaced apart from the latching edge and the actuating means is releasably fixed.
  • actuating means with the pressure area for its part engages behind the lower side of the retaining catch after it has been displaced and latches there. In this way, the actuating means is held in position and at the same time the retaining catch is held in the depressed state.
  • the holding of the actuating means is preferably only maintained until the pivoting movement of the plate wings begins. In a preferred embodiment, this can be effected by the spring means themselves.
  • the spring means acting on the actuating means are dimensioned such that, after the latching means have been released, they press the fixable plate wing slightly upwards, so that springing back of the latching means can no longer bring about latching. If the user presses down the handle with a pressure force that exceeds the spring force, the actuating means will initially remain in the lower, second position. If, on the other hand, he does not press the handle downwards or only slightly, in this configuration the wiping plate will stand up slightly with the fixable plate wing pivoting slightly upwards, so that the actuating means springs back into its starting position.
  • the springing back can also take place later, with larger pivoting angles of the fixable panel wing.
  • the subsequent folding down of the released, fixable plate wing causes the actuating means with the latched pressure area to move away from the retaining catch, so that its locking is canceled again by the movement of the plate wing and the retaining catch, now hanging freely, can bounce back.
  • a spring means is preferably provided, which returns the actuating means to the starting position when this additional locking position is released.
  • the second latching possibility of the actuating means has the advantage that the latching means for locking the panel wings are deactivated until the panel wings are folded down.
  • the user can, for example, press down the actuating means designed as a foot pedal and lock it in the second detent position.
  • the panel wings are now released.
  • the wiping plate is lifted, they then swing downwards, which automatically cancels the latching of the actuating means, since the actuating means also folds down with the fixable panel wing and thus the underside of the retaining catch is no longer gripped by the pressure area of the actuating means.

Description

Die Erfindung betrifft eine klappbare Wischplatte nach dem Oberbegriff des Anspruchs 1. Die bekannten Wischplatten werden insbesondere in Verbindung mit Bodenwischern eingesetzt und tragen üblicherweise einen aufgesteckten oder angeklemmten Wischbelag oder -bezug. Zum Trockenschleudern in einer Trocknungsvorrichtung oder Auspressen in einer Wischmittelpresse oder auch nur zum Abnehmen des Wischbelags kann die Wischplatte zusammengeklappt werden, wobei die beiden Plattenflügel an einer gemeinsamen oder an zwei benachbarten Achsen schwenkbar gelagert sind und nach Lösen einer Arretierung von dem im Abstand zum Boden gehaltenen Wischgerät herunterklappen können, so dass die Unterseiten der Plattenflügel auf einander zu bewegt werden und der zum Beispiel an den äußeren Enden der Plattenflügel befestigte Wischbelag herunterhängt oder abgenommen werden kann.The invention relates to a foldable wiping plate according to the preamble of claim 1. The known wiping plates are used in particular in connection with floor wipers and usually have a wiper covering or cover that is attached or clamped on. The wiping plate can be folded up to spin dry in a drying device or to press out in a wiping agent press or even just to remove the wiping covering, with the two plate wings being pivotably mounted on a common axis or on two adjacent axes and after releasing a lock from the one held at a distance from the floor Mopping device can fold down so that the undersides of the plate wings are moved towards each other and the wiper pad attached, for example, at the outer ends of the plate wings hangs down or can be removed.

Wischmittel, die am unteren Ende eines Stiels eines Wischgerätes angeordnet sind, sind zum Beispiel ebene Textil- oder Schaumstofflagen. Es können aber auch die in der EP 2 868 250 A1 in Verbindung mit einem Fransenmopp beschriebenen Wischmittel, Wischfasern oder -schnüre oder ähnlichen Materialien zum Befeuchten, Reinigen und bzw. oder Trocknen von Oberflächen sein. Die Erfindung kann ferner zum Beispiel in Verbindung mit einer aus der EP 2 811 840 A1 bekannten Wischmittelpresse verwendet werden. Letztlich ist die Erfindung aber nicht auf spezielle Ausgestaltungen des Bodenwischers und des Wischbelags beschränkt.Wiping means, which are arranged at the lower end of a handle of a wiping device, are, for example, flat textile or foam layers. But it can also be in the EP 2 868 250 A1 wiping means, wiping fibers or cords or similar materials described in connection with a fringed mop for moistening, cleaning and/or drying surfaces. The invention can also be used, for example, in connection with one of EP 2 811 840 A1 known wiping agent press can be used. Ultimately, however, the invention is not limited to special configurations of the floor wiper and the wiper covering.

Eine gattungsgemäße Wischplatte ist aus der WO 2013/156100 A1 bekannt. Die dort beschriebene Wischplatte weist einen Gelenkadapter mit einer gelenkig daran befestigten Stielaufnahme auf, über die ein Stiel lösbar oder fest an dem Gelenkadapter, meist über eine kardanische Lagerung, befestigt ist. Ferner weist die Wischplatte einen, um eine erste Schwenkachse schwenkbar an dem Gelenkadapter angelenkten, festlegbaren Plattenflügel auf, der nicht nur selbst festlegbar ist, sondern über den ein zweiter, passiver Plattenflügel in Gebrauchsposition des Bodenwischers gehalten ist. Dies wird bei der gattungsgemäßen Wischplatte über eine zahnradähnliche Verzahnung realisiert, die an gegenüberliegenden Enden der Wischplatte vorgesehen ist, wobei durch den Eingriff der Zähne die Schwenkbewegung der beiden Plattenflügel synchronisiert bzw. bei Blockieren eines Plattenflügels dann auch unterbunden ist.A generic wiper plate is from WO 2013/156100 A1 known. The mop plate described there has an articulated adapter with a handle mount attached to it in an articulated manner, via which a handle is detachably or firmly attached to the articulated adapter, usually via a gimbal mount. Furthermore, the wiping plate has a fixable plate wing pivoted about a first pivot axis on the joint adapter, which can not only be fixed itself, but also via a second, passive plate wing in the usage position of the floor wiper is held. This is realized in the generic mop plate via gear-like teeth provided at opposite ends of the mop plate, the pivoting movement of the two plate wings being synchronized by the meshing of the teeth or then also being prevented if one plate wing is blocked.

Der passive Plattenflügel ist bei dieser Ausgestaltung an einer zweiten Achse schwenkbar gelagert, so dass die oben beschriebene Verzahnung umgesetzt werden kann. Dies ist aber für die Umsetzung der vorliegenden Erfindung nicht notwendig, der passive Plattenflügel könnte ebenso gut auch mit dem festlegbaren Plattenflügel zusammen an einer gemeinsamen Achse gelagert sein. Beide Plattenflügel bilden in jedem Fall in Gebrauchsposition mit ihren Unterseiten eine ebene, über einen Boden bewegbare Fläche, wobei die Plattenflügel in einer Wechsel- oder Trocknungsposition mit den Unterseiten einander gegenüberliegend oder sogar aneinander anliegend nach unten geklappt sind.In this configuration, the passive panel wing is mounted pivotably on a second axis, so that the toothing described above can be implemented. However, this is not necessary for the implementation of the present invention; the passive panel wing could just as well be mounted together with the fixable panel wing on a common axis. In any case, in the use position, the undersides of both panel wings form a flat surface that can be moved over a floor, with the panel wings being folded down in a changing or drying position with the undersides opposite one another or even abutting one another.

Natürlich ist bei einem reinen Anheben des Wischgerätes ein Zusammenklappen der Plattenflügel, evtl. sogar mit einem Herunterfallen des Wischbelags, unerwünscht. Um die Arretierung der Plattenflügel in der Gebrauchsposition zu ermöglichen, sind diese daher nicht nur schwenkbar an dem Gelenkadapter angelenkt, sondern über Rastmittel in der Gebrauchsstellung festgelegt. Hierzu ist eine Rastverbindung mit zumindest einer Halteraste und zumindest einer Rastkante vorgesehen, die zusammen eine lösbare Verbindung zum Halten der Plattenflügel bilden. Über ein Betätigungsmittel kann eine Lösevorrichtung zum Lösen der Rastmittel bedient werden, so dass der festlegbare Plattenflügel nach dem Lösen um die erste Schwenkachse schwenkbar wird und bei angehobenen Wischgerät herunterklappt. Da der festlegbare Plattenflügel den passiven Plattenflügel nur in der Gebrauchsstellung festlegen muss, wird durch seine Schwenkbewegung auch der passive Plattenflügel zumindest insoweit freigegeben, dass dieser ebenfalls schwenkbar ist. Dies wird bei den bekannten Wischplatten durch die Verzahnung erreicht.Of course, when the mopping device is simply raised, it is undesirable for the panel wings to collapse, possibly even with the mopping covering falling down. In order to enable the panel wings to be locked in the position of use, they are therefore not only articulated in a pivotable manner on the joint adapter, but are also fixed in the position of use by means of locking means. For this purpose, a latching connection is provided with at least one retaining latch and at least one latching edge, which together form a detachable connection for holding the panel wings. A release device for releasing the locking means can be operated via an actuating means, so that the fixable plate wing can be pivoted about the first pivot axis after release and folds down when the mopping device is raised. Since the fixable panel wing only has to fix the passive panel wing in the position of use, its pivoting movement also releases the passive panel wing at least to the extent that it can also be pivoted. In the case of the known wiper plates, this is achieved by the toothing.

Die oben beschriebene, bekannte Wischplatte hat den Nachteil, dass die Verzahnung aufwendig ist, die Gefahr des "Überspringens" von Zähnen oder des Abbrechens von Zähnen besteht und dass Schmutz oder Teile des Wischmittels in die Verzahnung geraten können, was die Funktion beeinträchtigen kann.The known wiper plate described above has the disadvantage that the toothing is complex, there is a risk of teeth “skipping” or teeth breaking off, and that dirt or parts of the wiping medium can get into the toothing, which can impair the function.

Eine andere Lösung, bei der der festlegbare Plattenflügel über einen, eine Plattenverriegelung bildenden Abschnitt einen über dessen Schwenkachse hinausgehenden Teil des passiven Plattenflügels überdeckt und ihn so in der Gebrauchsstellung festlegt, ist aus der EP 1 764 024 A1 bekannt. Hier wird die Arretierung durch ein Fußpedal als Bedienmittel aufgehoben, das als Wippe ausgebildet ist und die Rastverbindung, die die beiden Plattenflügel in Gebrauchsposition hält, aufhebelt. Nachteilig hier ist die Tatsache, dass vergleichsweise hohe Kräfte erforderlich sind und die Bewegung der Wippe eine gewisse Bauhöhe bzw. einen Abstand zum Fußboden erfordert.Another solution, in which the fixable panel wing covers a part of the passive panel wing that extends beyond its pivot axis and thus fixes it in the position of use, is a section forming a panel lock EP 1 764 024 A1 known. Here the locking is released by a foot pedal as an operating means, which is designed as a rocker and the latching connection that holds the two panel wings in the position of use, levers open. A disadvantage here is the fact that comparatively high forces are required and the movement of the seesaw requires a certain overall height or a distance from the floor.

Weitere klappbare Wischplatten sind aus der DE 10 2013 107 316 B3 und der WO 2008/043538 A2 bekannt. Auch bei diesen Ausgestaltungen blockieren sich die Plattenflügel gegenseitig und werden durch Lösen eines Plattenflügels in Schwenkrichtung beweglich. Allerdings wäre bezüglich dieser Wischplatten eine einfachere Konstruktion, insbesondere hinsichtlich des Gelenkadapters, wünschenswert. Schließlich ist aus der DE 10 2018 112 821 A1 mit sich gegenseitig verriegelnden Plattenflügeln und einer Lösemöglichkeit über ein Fußpedal bekannt. Die EP 3 785 595 A1 wieder zeigt eine ähnliche Wischplatte, wobei hier allerdings die Kraft zur Lösung der verrasteten Wischplatten über eine spontane Abbremsung des Wischgerätes nach einer Abwärtsbewegung erzeugt wird.More foldable wiper plates are from the DE 10 2013 107 316 B3 and the WO 2008/043538 A2 known. In these configurations, too, the plate wings block each other and become movable in the pivoting direction by releasing a plate leaf. However, with regard to these wiping plates, a simpler construction, in particular with regard to the joint adapter, would be desirable. Finally is out of the DE 10 2018 112 821 A1 known with interlocking panel wings and a release option via a foot pedal. The EP 3 785 595 A1 again shows a similar wiping plate, although here the force for releasing the locked wiping plates is generated via spontaneous braking of the wiping device after a downward movement.

Aufgabe der Erfindung ist es daher, eine klappbare Wischplatte zu schaffen, die bei leichter Bedienbarkeit einfach und kostengünstig herstellbar ist sowie eine zuverlässige Funktion ermöglicht.It is therefore the object of the invention to create a foldable mop plate which, while being easy to operate, can be produced simply and cost-effectively and enables reliable operation.

Diese Aufgabe wird nach der Erfindung durch eine Wischplatte mit den Merkmalen des Anspruchs 1 gelöst. Die erfindungsgemäße Wischplatte weist nun insbesondere einen mit den Rastmitteln zusammenwirkenden, elastisch verformbaren Bereich auf, der bei Betätigung der Betätigungsmittel durch die Lösevorrichtung verformt wird, wobei durch die Verformung die Rastkante und die Halteraste außer Eingriff geraten. Dies ermöglicht es, auf unnötige Bauteile, aufwändige Lagerungen und eine Verzahnung der Plattenflügelränder zu verzichten. Die Lösevorrichtung ist hier von einem Betätigungsmittel gebildet, dass der Benutzer mit dem Fuß oder mit der Hand bedienen kann. Wie auch schon bei den oben beschriebenen, bekannten Wischplatten ist dieses Betätigungsmittel bevorzugt ein Fußpedal.According to the invention, this object is achieved by a wiping plate having the features of claim 1 . The wiper plate according to the invention has in particular an elastically deformable area which interacts with the latching means and which is deformed by the release device when the actuating means are actuated, the latching edge and the retaining latch being disengaged as a result of the deformation. This makes it possible to do without unnecessary components, complex bearings and toothing of the panel wing edges. The release device is formed here by an actuating means that the user can operate with his foot or with his hand. As with the known mop plates described above, this actuating means is preferably a foot pedal.

Bei einer bevorzugten Ausgestaltung der Erfindung sind die Rastmittel von wenigstens einer Halteraste und einer hiermit korrespondierenden Rastkante gebildet. Es handelt sich also um ein formschlüssiges Hintergreifen der Rastkante durch die Halteraste. Natürlich können auch mehrere Paarungen von Halterasten und Rastkanten vorgesehen sein oder es können auch mehrere Halterasten eine gemeinsame Rastkante oder alternativ eine Halteraste mehrere Rastkanten hintergreifen. Letztlich ist dies eine Frage der Dimensionierung der Rastmittel, damit diese die notwendigen Kräfte aufnehmen können. Diese Kräfte sind allerdings bei den üblichen Wischplatten nicht besonders groß, da die Rastmittel ja nur verhindern sollen, dass bei Anheben des Wischgerätes die Plattenflügel der Wischplatte ungewollt nach unten klappen. Somit muss die Rastverbindung im Wesentlichen das Gewicht der Plattenflügel und des daran hängenden, feuchten Wischbelags halten können. Bevorzugt sind die Rastmittel dabei so ausgebildet, dass die Belastung der Wischplatte in der Gebrauchsposition bzw. das Überführen der Plattenflügel in die Gebrauchsposition durch den Benutzer eine selbsttätige Einrastung auslöst.In a preferred embodiment of the invention, the latching means are formed by at least one holding latch and a latching edge corresponding thereto. It is therefore a form-fitting engagement of the locking edge by the retaining catch. Of course, several pairs of retaining catches and locking edges can also be provided, or multiple retaining catches can also engage behind a common locking edge or, alternatively, a retaining catch can engage multiple locking edges. Ultimately, this is a question of dimensioning the latching means so that they can absorb the necessary forces. However, these forces are not particularly large in the case of the usual wiping plates, since the latching means are only intended to prevent the plate wings of the wiping plate from unintentionally folding down when the wiping device is lifted. The snap-in connection must therefore essentially be able to hold the weight of the panel wings and the damp wiper covering hanging from them. The locking means are preferably designed in such a way that the loading of the wiping plate in the position of use or the transfer of the plate wings into the position of use by the user triggers an automatic locking.

In der Gebrauchsstellung mit verriegelten Rastmitteln hintergreift die Halteraste die Rastkante. Bevorzugt ist dabei die Wischplatte so ausgebildet, dass spätestens bei Belastung der Wischplatte durch den Benutzer die Rastverbindung einrastet. Um zum Auspressen, Ausschleudern oder zum Wechseln des Wischbelages die Plattenflügel beim Anheben der Wischplatte herunterklappen zu können, ist die Lösevorrichtung vorgesehen.In the position of use with the latching means locked, the retaining latch engages behind the latching edge. The wiping plate is preferably designed in such a way that the locking connection engages at the latest when the wiping plate is loaded by the user. The release device is provided in order to be able to fold down the plate wings when lifting the wiping plate for squeezing out, spinning out or changing the wiping covering.

Bevorzugt wird nur einer der beiden Plattenflügel, der im Zusammenhang mit der Beschreibung der vorliegenden Erfindung als "festlegbarer Plattenflügel" bezeichnet wird, über die Rastmittel gehalten. Zur Umsetzung der Funktion der Wischplatte ist dies ausreichend, da entweder der andere, im Zusammenhang mit dieser Erfindung als "passiver Plattenflügel" bezeichnete Plattenflügel, sofern denn ein zweiter Plattenflügel vorhanden ist, feststehend ausgebildet sein kann oder, sofern er ebenfalls schwenkbar ist, über den festlegbaren Plattenflügel gehalten sein kann. Dies erfolgt zum Beispiel über eine Plattenverriegelung, die von einem Blockierabschnitt gebildet ist.Preferably, only one of the two panel wings, which is referred to in connection with the description of the present invention as "fixable panel wings", is held by the latching means. This is sufficient to implement the function of the wiping plate, since either the other plate wing, referred to in connection with this invention as a "passive plate wing", can be fixed if there is a second plate wing or, if it can also be pivoted, via the fixable plate wing can be held. This is done, for example, via a panel lock formed by a blocking portion.

Der Blockierabschnitt ist am passiven Plattenflügel angeordnet und wird von einem Bereich des festlegbaren Plattenflügels in der Gebrauchsstellung überdeckt. Der Blockierabschnitt ist dabei so angeordnet, dass er bei Herunterklappen des passiven Plattenflügels nach oben geschwenkt werden muss. Da dies erst dann möglich ist, wenn der überdeckende Bereich des festlegbaren Plattenflügels durch Herunterklappen des festlegbaren Plattenflügels die Bewegung des Blockierabschnitts freigibt, wird der passive Plattenflügel bis zu dessen Freigabe in Position gehalten. Zur Umsetzung dieses Details kommen verschiedenste Konstruktionen in Betracht, insbesondere wird der Blockierabschnitt aus Sicht des äußeren Endes des passiven Plattenflügels bevorzugt die Schwenkachse des passiven Plattenflügels überragen, so dass er beim Schwenken automatisch nach oben bewegt wird. Dieser, die Schwenkachse überragende Blockierabschnitt kann auch in das innere Ende des Plattenflügels, in das ein Bolzen, um den der Plattenflügel für schwenkbar ist, eingeschoben ist, eingearbeitet sein.The blocking section is arranged on the passive panel wing and is covered by an area of the fixable panel wing in the position of use. The The blocking section is arranged in such a way that it has to be pivoted upwards when the passive panel wing is folded down. Since this is only possible when the covering area of the fixable panel wing releases the movement of the blocking section by folding down the fixable panel wing, the passive panel wing is held in position until it is released. A wide variety of constructions can be considered for implementing this detail, in particular the blocking section will preferably protrude beyond the pivot axis of the passive panel wing when viewed from the outer end of the passive panel wing, so that it is automatically moved upwards when pivoting. This blocking section, which protrudes beyond the pivot axis, can also be incorporated into the inner end of the panel wing, into which a bolt, about which the panel wing can be pivoted, is inserted.

Das elastisch verformbare Bauteil kann sowohl der festlegbare Plattenflügel als auch bevorzugt der Gelenkadapter oder ein Teil hiervon, auch ein Anbauteil, sein. Nachfolgend wird die Erfindung anhand eines verformbaren Gelenkadapters beschrieben. In kinematischer Umkehr kann natürlich der elastisch verformbare Bereich auch an dem festlegbaren Plattenflügel vorgesehen sein. Wesentliches Merkmal ist lediglich die Tatsache, dass das Betätigungsmittel diesen elastisch verformbaren Bereich deformiert und das einer der beiden Teile der Rastverbindung an diesem Bereich angeordnet ist und derart ausgebildet ist, dass die Deformation dazu führt, dass der formschlüssige Untergriff der Rastkante unter die Halteraste aufgehoben ist.The elastically deformable component can be both the fixable plate wing and preferably the joint adapter or a part thereof, also an add-on part. The invention is described below using a deformable joint adapter. In kinematic reversal, of course, the elastically deformable area can also be provided on the fixable panel wing. The only essential feature is the fact that the actuating means deforms this elastically deformable area and that one of the two parts of the snap-in connection is arranged in this area and is designed in such a way that the deformation means that the form-fitting grip of the snap-in edge under the retaining catch is eliminated .

Der Gelenkadapter ist bei einer Ausgestaltung der Erfindung ein zentrales Mittelstück der Wischplatte. Hieran sind ein oder zwei Achsen gelagert, über die die Plattenflügel schwenkbar an dem Gelenkadapter angelenkt sind. Ferner weist der Gelenkadapter üblicherweise eine Stielaufnahme auf, über die ein Stiel des Wischgerätes mit der Wischplatte verbunden werden kann. Dieser zum Beispiel in Form eines kleinen, schiffchenartigen oder quaderförmigen Körpers ausgebildete Gelenkadapter wird nun erfindungsgemäß zusätzlich genutzt, um eine leicht lösbare Rastvorrichtung bereitzustellen.In one embodiment of the invention, the articulated adapter is a central middle piece of the wiping plate. One or two axes are mounted on this, via which the panel wings are articulated in a pivotable manner on the joint adapter. Furthermore, the articulated adapter usually has a handle receptacle via which a handle of the mopping device can be connected to the mopping plate. This joint adapter, which is designed, for example, in the form of a small, boat-like or cuboid body, is now additionally used according to the invention to provide an easily detachable latching device.

Das dem festlegbaren Plattenflügel zugewandte Ende des Gelenkadapters ist bei einer Ausgestaltung der elastische Bereich und trägt die Halteraste. Hierzu kann die entsprechende Seitenwand des Gelenkadapters mit zwei vertikalen und einem horizontalen, unteren Spalt versehen sein, der aus der Wandung des Gelenkadapters eine im oberen Bereich mit dem übrigen Wandteilen des Gelenkadapters verbundene Federzunge herausarbeitet. An dem elastischen Bereich springt in Richtung des festlegbaren Plattenflügels die Halteraste lippen- oder nasenartig hervor. Die am festlegbaren Plattenflügel angeordnete Rastkante wiederum hintergreift diesen hervorspringenden Bereich der Halteraste. Es ist offensichtlich, dass in kinematischer Umkehr die Halteraste auch an dem festlegbaren Plattenflügel vorgesehen sein kann, die dann eine Rastkante an der Wandung des Gelenkadapters hintergreift oder in ein Fenster in der Wandung des Gelenkadapters eingreift.In one embodiment, the end of the joint adapter facing the fixable plate wing is the elastic area and carries the retaining catch. For this, the corresponding side wall of the articulated adapter can be provided with two vertical and one horizontal, lower gap, which works out a spring tongue connected in the upper area to the remaining wall parts of the articulated adapter from the wall of the articulated adapter. On the elastic area, the retaining latch protrudes like a lip or nose in the direction of the panel wing that can be fixed. The latching edge arranged on the fixable panel wing in turn engages behind this protruding area of the retaining latch. It is obvious that, in kinematic reversal, the retaining latch can also be provided on the fixable plate wing, which then engages behind a latching edge on the wall of the articulated adapter or engages in a window in the wall of the articulated adapter.

Durch das insbesondere als Fußpedal ausgebildete Betätigungsmittel kann der Benutzer nun die Rastverbindung lösen. Das Betätigungsmittel weist hierzu einen vorspringenden Druckbereich auf, der bei einer Betätigungsbewegung des Betätigungsmittels, beispielsweise bei Niederdrücken des oben genannten Fußpedals, gegen den elastischen Bereich bewegt ist und diesen dann nachfolgend eindrückend deformiert. Auch eine Verlagerung eines verschiebbar am Gelenkadapter gelagerten Teils kann natürlich hier in Betracht kommen. In beiden Fällen ist das Betätigungsmittel an dem festlegbaren Plattenflügel beweglich so gelagert, dass sich zwangsläufig bei der Betätigung die Anstellung an den elastischen Bereich ergibt.The user can now release the locking connection by means of the actuating means, which is designed in particular as a foot pedal. For this purpose, the actuating means has a protruding pressure area, which is moved against the elastic area during an actuation movement of the actuating means, for example when the above-mentioned foot pedal is depressed, and then subsequently deforms it in a pressing manner. Displacement of a part that is displaceably mounted on the joint adapter can of course also be considered here. In both cases, the actuation means is movably mounted on the fixable plate wing in such a way that the actuation inevitably results in the employment of the elastic area.

Die oben beschriebene Federzunge ist nicht die einzige Möglichkeit, über die sich der elastische Bereich realisieren lässt. Zum einen kann auch die Halteraste selbst verschiebbar und gegen eine elastische Kraft eindrückbar gelagert sein. Ferner kann der gesamte Gelenkadapter verformbar sein. Schließlich ist es auch möglich, den gleichen Effekt dadurch zu erzielen, dass der festlegbare Plattenflügel in Querrichtung gegen eine Federkraft verschiebbar an dem Gelenkadapter gelagert ist. Hier würde also der elastische Bereich die Lagerung des Plattenflügel sein, wobei durch das Betätigungsmittel der festlegbare Plattenflügel ein kleines Stück nach außen gedrückt wird, wodurch die Rastmittel außer Eingriff gelangen.The spring tongue described above is not the only way of realizing the elastic area. On the one hand, the retaining latch itself can be mounted so that it can be displaced and pressed in against an elastic force. Furthermore, the entire joint adapter can be deformable. Finally, it is also possible to achieve the same effect in that the plate wing that can be fixed is mounted on the articulated adapter so that it can be displaced in the transverse direction against a spring force. In this case, the elastic area would therefore be the mounting of the panel wing, with the actuation means pressing the fixable panel wing outwards a little, as a result of which the latching means disengage.

In allen Fällen ist es bevorzugt, wenn nach dem Entrasten der die Plattenflügel haltenden Rastmittel durch die Verformung des elastisch verformbaren Bereichs eine weitere Rastmöglichkeit für das Betätigungsmittel vorgesehen ist, in der die räumliche Beabstandung der Rastmittel unter Freigabe der Schwenkbarkeit des festlegbaren Plattenflügels gehalten werden kann. Diese Möglichkeit ist ein besonders positiver Effekt der erfindungsgemäßen Lösung. Hierzu ist bei einer Ausgestaltung vorgesehen, dass das Betätigungsmittel nach einer ersten Bewegungsphase, in deren Verlauf der Druckbereich zum Lösen der Rastmittel den elastisch verformbaren oder verschiebbar gelagerten Bereich eingedrückt hat, bei Halten dieser Verformung einrasten kann. In dieser Position des Betätigungsmittels ist dann die Halteraste von der Rastkante beabstandet und das Betätigungsmittel ist lösbar festgelegt. Dies kann zum Beispiel dadurch geschehen, dass das Betätigungsmittel mit dem Druckbereich seinerseits die untere Seite der Halteraste nach deren Verdrängung hintergreift und dort verrastet. So wird das Betätigungsmittel in Position und gleichzeitig die Halteraste im eingedrückten Zustand gehalten.In all cases, it is preferred if, after the latching means holding the plate wings has been released, a further latching possibility is provided for the actuating means by the deformation of the elastically deformable region, in which the spatial Spacing of the locking means can be kept while releasing the pivotability of the fixable plate wing. This possibility is a particularly positive effect of the solution according to the invention. For this purpose, one embodiment provides that the actuating means can engage after a first movement phase, during which the pressure area for releasing the locking means has pressed in the elastically deformable or displaceably mounted area, while maintaining this deformation. In this position of the actuating means, the retaining latch is spaced apart from the latching edge and the actuating means is releasably fixed. This can be done, for example, in that the actuating means with the pressure area for its part engages behind the lower side of the retaining catch after it has been displaced and latches there. In this way, the actuating means is held in position and at the same time the retaining catch is held in the depressed state.

Das Halten des Betätigungsmittels wird bevorzugt nur solange aufrechterhalten, bis die Schwenkbewegung der Plattenflügel einsetzt. Dies kann bei einer bevorzugten Ausgestaltung durch die Federmittel selbst bewirkt sein. In diesem Fall sind die auf das Betätigungsmittel wirkenden Federmittel so dimensioniert, dass sie nach dem Lösen der Rastmittel den festlegbaren Plattenflügel leicht nach oben drücken, so dass ein Rückfedern der Rastmittel keine Verrastung mehr bewirken kann. Wenn der Benutzer den Stiel mit einer die Federkraft übersteigenden Druckkraft herunterdrückt, wird hier zunächst das Betätigungsmittel in der unteren, zweiten Position verbleiben. Drückt er den Stiel dagegen nicht oder nur leicht nach unten, wird sich bei dieser Ausgestaltung die Wischplatte leicht unter geringem Schwenken des festlegbaren Plattenflügels nach oben aufstellen, so dass das Betätigungsmittel wieder in seine Ausgangsposition zurückfedert.The holding of the actuating means is preferably only maintained until the pivoting movement of the plate wings begins. In a preferred embodiment, this can be effected by the spring means themselves. In this case, the spring means acting on the actuating means are dimensioned such that, after the latching means have been released, they press the fixable plate wing slightly upwards, so that springing back of the latching means can no longer bring about latching. If the user presses down the handle with a pressure force that exceeds the spring force, the actuating means will initially remain in the lower, second position. If, on the other hand, he does not press the handle downwards or only slightly, in this configuration the wiping plate will stand up slightly with the fixable plate wing pivoting slightly upwards, so that the actuating means springs back into its starting position.

Je nach Ausgestaltung kann das Zurückfedern auch später, bei größeren Schwenkwinkeln des festlegbaren Plattenflügels erfolgen. In beiden Fällen wir aber durch das nachfolgende Herunterklappen des freigegebenen, festlegbaren Plattenflügels sich nachfolgend dann das Betätigungsmittel mit dem verrasteten Druckbereich wieder von der Halteraste wegbewegen, so dass dessen Verrastung durch die Bewegung des Plattenflügels wieder aufgehoben wird und die Halteraste dann, jetzt frei hängend, wieder ausfedern kann. Gleichzeitig ist bevorzugt ein Federmittel vorgesehen, das bei Lösen dieser zusätzlichen Rastposition das Betätigungsmittel wieder in die Ausgangsstellung zurückstellt.Depending on the configuration, the springing back can also take place later, with larger pivoting angles of the fixable panel wing. In both cases, however, the subsequent folding down of the released, fixable plate wing causes the actuating means with the latched pressure area to move away from the retaining catch, so that its locking is canceled again by the movement of the plate wing and the retaining catch, now hanging freely, can bounce back. At the same time, a spring means is preferably provided, which returns the actuating means to the starting position when this additional locking position is released.

Die zweite Rastmöglichkeit des Betätigungsmittels hat den Vorteil, dass bis zum Herunterklappen der Plattenflügel die Rastmittel zum Verriegeln der Plattenflügel deaktiviert sind. Der Benutzer kann also bei auf dem Boden liegender Wischplatte zum Beispiel die als Fußpedal ausgebildeten Betätigungsmittel niederdrücken und in der zweiten Rastposition verriegeln. Die Plattenflügel sind nun freigegeben. Bei Anheben der Wischplatte schwingen sie dann nach unten, wodurch die Verrastung der Betätigungsmittel selbsttätig aufgehoben ist, da mit dem festlegbaren Plattenflügel auch das Betätigungsmittel herunterklappt und damit das Hintergreifen der Unterseite der Halteraste durch den Druckbereich des Betätigungsmittels aufgehoben ist. Durch Federmittel wird dann das Betätigungsmittel wieder in die Ursprungsposition zurückgestellt.The second latching possibility of the actuating means has the advantage that the latching means for locking the panel wings are deactivated until the panel wings are folded down. When the wiping plate is lying on the floor, the user can, for example, press down the actuating means designed as a foot pedal and lock it in the second detent position. The panel wings are now released. When the wiping plate is lifted, they then swing downwards, which automatically cancels the latching of the actuating means, since the actuating means also folds down with the fixable panel wing and thus the underside of the retaining catch is no longer gripped by the pressure area of the actuating means. The actuating means is then returned to the original position by spring means.

In Figur 1 ist eine erfindungsgemäße Wischplatte in einer Seitenansicht dargestellt. Die Wischplatte weist im mittleren Bereich einen Gelenkadapter 5 mit einer kardanischen Stiellagerung 6 auf, über die eine Stielaufnahme 1 zu Befestigung eines Stiels an dem Gelenkadapter 5 befestigt ist. Der Gelenkadapter 5 ist hier als Baukörper mit einem im wesentlichen rechteckigen Querschnitt ausgebildet, in dem eine erste Schwenkachse 7 und eine zweite Schwenkachse 8 gelagert sind. Die Schwenkachsen 7,8 halten schwenkbar auf der linken Seite einen festlegbaren Plattenflügel 2 und auf der rechten Seite einen passiven Plattenflügel 3. Die beiden Plattenflügel 2,3 sind über eine im Verlauf dieser Beschreibung noch detailliert beschriebene Rastverbindung miteinander und mit dem Gelenkadapter 5 über Rastmittel verrastet.In figure 1 a wiper plate according to the invention is shown in a side view. In the middle area, the mop plate has a joint adapter 5 with a cardanic handle bearing 6 via which a handle receptacle 1 for fastening a handle is attached to the joint adapter 5 . The joint adapter 5 is designed here as a structure with an essentially rectangular cross section, in which a first pivot axis 7 and a second pivot axis 8 are mounted. The pivot axes 7.8 pivotally hold a fixable panel wing 2 on the left side and a passive panel wing 3 on the right side. The two panel wings 2.3 are locked with one another and with the joint adapter 5 via locking means via a locking connection that will be described in detail in the course of this description.

Zur Aufhebung der Verrastung sind Betätigungsmittel 4 vorgesehen, die hier von einem Fußpedal gebildet sind. Das Fußpedal ist auf der Oberseite des festlegbaren Plattenflügels 2 etwa im mittleren Bereich schwenkbar gelagert. Zum Lösen der Verrastung kann es in Richtung des Pfeils I niedergedrückt bzw. heruntergetreten werden. Nach Lösen der Rastverbindung klappen dann der festlegbare Plattenflügel 2 und der passive Plattenflügel 3 in Richtung der Pfeile II herunter. In Figur 2 ist die in Figur 1 dargestellte Ausgestaltung in einer Ansicht von oben dargestellt. Hier ist zu erkennen, dass der Gelenkadapter 5 im Vergleich zu den Plattenflügeln 2, 3 kompakt mit einem im Bodenbereich rechteckigen Querschnitt ausgebildet ist.Actuating means 4, which are formed here by a foot pedal, are provided to release the latching. The foot pedal is mounted pivotably on the upper side of the fixed panel wing 2 approximately in the central area. To release the latch, it can be depressed or stepped down in the direction of arrow I. After releasing the locking connection, the fixable panel wing 2 and the passive panel wing 3 fold down in the direction of the arrows II. In figure 2 is the in figure 1 shown embodiment shown in a view from above. Here it can be seen that the joint adapter 5 is compact in comparison to the panel wings 2, 3 with a rectangular cross-section in the bottom area.

Figur 3 zeigt die Wischplatte in einer Seitenansicht im Schnitt. Die Figur 4 zeigt die Einzelheit X aus Figur drei in vergrößerte Darstellung, während in Figur 5 die Einzelheit Z aus Figur 4 in einer vergrößerten Darstellung dargestellt ist. In allen drei Figuren ist die Rastverbindung über die Rastmittel sowie auch das gegenseitige Halten der Plattenflügel 2,3 zu erkennen. figure 3 shows the wiper plate in a side view in section. The figure 4 shows the detail X from Figure three in an enlarged representation, while in figure 5 the detail Z out figure 4 is shown in an enlarged view. In all three figures, the latching connection via the latching means as well as the mutual holding of the plate wings 2.3 can be seen.

Das als Fußpedal eingesetzte Betätigungsmittel 4 kann vom Benutzer mit dem Fuß heruntergetreten werden. Ein Federmittel 10 drückt es in die in den Figuren 3 und 4 dargestellte Ausgangsposition. Im vorderen Bereich weist das Betätigungsmittel 4 einen Druckbereich 9 auf, der bei Absenken des Betätigungsmittels 4 gegen einen elastisch verformbaren Bereich des Gelenkadapters 5 angestellt wird.The operating means 4 used as a foot pedal can be stepped down with the foot by the user. A spring means 10 pushes it into the Figures 3 and 4 shown starting position. In the front area, the actuating means 4 has a pressure area 9 which is placed against an elastically deformable area of the joint adapter 5 when the actuating means 4 is lowered.

Der elastisch verformbare Bereich hat im Wesentlichen die Form eines Hakens, der im unteren Bereich eine sich in Richtung der Außenseite des festlegbaren Plattenflügels 4 nach außen erstreckende Halteraste 11 aufweist. Diese Halteraste 11 untergreift im verriegelten Zustand, der in den Figuren 3-5 dargestellt ist, eine Rastkante 13 des festlegbaren Plattenflügels 2. Die von der Rastkante 13 und der Halteraste 11 gebildeten Rastmittel halten so in der in Figur 3 dargestellten Gebrauchsposition die Plattenflügel 2,3 fest, so dass ihre Unterseiten eine ebene Gesamtfläche bilden.The elastically deformable area is essentially in the form of a hook, which in the lower area has a retaining catch 11 that extends outward in the direction of the outside of the panel wing 4 that can be fixed in place. This retaining catch 11 engages under the locked state in the Figures 3-5 is shown, a latching edge 13 of the fixable panel wing 2. The latching means formed by the latching edge 13 and the retaining latch 11 hold in the in figure 3 shown position of use, the plate wings 2.3 firmly so that their undersides form a flat overall surface.

Durch Niederdrücken des Betätigungsmittels 4 wird nun der Druckbereich 9 des Fußpedals gegen diesen hakenförmigen, elastisch verformbaren Bereich des Gelenkadapters 5 gedrückt. Der Druckbereich 9 gerät dabei in Anlage an die Außenkontur des Gelenkadapters 5 und drückt den linken Bereich des Gelenkadapters 5 nach rechts. Hierdurch wird auch die Halteraste 11 nach rechts in Richtung der ersten Schwenkachse 7 verlagert, so dass ihre Überdeckung durch die Rastkante 13 aufgehoben wird. Wird nun das Betätigungsmittel 4 weiter niedergedrückt, untergreift der vorspringende Druckbereich 9 des Fußpedals die Halteraste 11, die in einen oberhalb des Druckbereiches 9 angeordneten, eingezogenen Bereich des Bedienmittels 4 zurückfedert.By depressing the actuating means 4, the pressure area 9 of the foot pedal is now pressed against this hook-shaped, elastically deformable area of the joint adapter 5. The pressure area 9 comes into contact with the outer contour of the joint adapter 5 and presses the left area of the joint adapter 5 to the right. As a result, the retaining catch 11 is also shifted to the right in the direction of the first pivot axis 7 so that it is no longer covered by the catch edge 13 . If the actuating means 4 is now depressed further, the protruding pressure area 9 of the foot pedal engages under the retaining catch 11 which springs back into a retracted area of the operating means 4 located above the pressure area 9 .

Damit das Zurückfedern des elastisch verformbaren Bereichs trotz des noch nicht heruntergeklappten, festlegbaren Plattenflügels 2 möglich ist, ist die Rastkante 13 entsprechend geformt, so dass der Druckbereich 9 die Rastkante 13 passieren kann. Hierzu ist die Rastkante 13 mittig unterbrochen, was am besten in Figur 7 zu sehen ist. Auf dies Weise ist das Bedienmittel 4 nach dem Niederdrücken oder Heruntertreten verrastet. Hebt der Benutzer nun das Wischgerät mit der Wischplatte an, klappen die beiden Plattenflügel 2,3 in Richtung der Pfeile II (vgl. Fig. 3) herunter. Dies wiederum führt dazu, dass das Bedienmittel 4 ebenfalls seitlich abklappt, wodurch es wiederum außer Eingriff mit der Halteraste 11 gerät. Das Federmittel 10 stellt dann das Fußpedal wieder zurück.In order that the springing back of the elastically deformable area is possible despite the not yet folded down, fixable panel wing 2 , the locking edge 13 is shaped accordingly, so that the pressure area 9 can pass the locking edge 13 . For this purpose, the locking edge 13 is interrupted in the middle, which is best done in figure 7 you can see. In this way, the operating means 4 is locked after being pressed down or stepped down. If the user now lifts the mopping device with the mopping plate, the two plate wings 2, 3 fold in the direction of the arrows II (cf. 3 ) down. This in turn means that the operating means 4 also folds out laterally, as a result of which it in turn disengages from the retaining catch 11 . The spring means 10 then resets the foot pedal.

Weiterhin ist in den Figuren 4 und 5 die Lagerung der Plattenflügel 2, 3 zu erkennen. Insbesondere in Figur 5 ist zu erkennen, dass der festlegbare Plattenflügel 2 mit einem seitlich nach rechts ragendem Ausleger einen Rand der Lagerung des passiven Plattenflügels 3 überragt. Dieser Ausleger bildet einen Blockierabschnitt 12, der den passiven Plattenflügel 3 in der Gebrauchsposition hält. Erst dann, wenn der passive Plattenflügel 3 durch Herunterklappen des festlegbaren Plattenflügels 2 freigegeben wird, in dem der Blockierabschnitt 12 durch Drehung um die erste Schwenkachse 7 aus dem Bewegungsbereich der Lagerung des passiven Plattenflügel 3 an der zweiten Schwenkachse 8 herausgedreht ist, kann auch der passive Plattenflügel 3 nach unten klappen.Furthermore, in the Figures 4 and 5 the storage of the plate wings 2, 3 to recognize. In particular figure 5 it can be seen that the fixable panel wing 2 protrudes beyond an edge of the mounting of the passive panel wing 3 with a laterally to the right projecting arm. This cantilever forms a blocking portion 12 which holds the passive panel wing 3 in the position of use. The passive Fold panel wings 3 down.

Durch die gegenseitige Verriegelung der Plattenflügel 2,3 kann ohne großen Aufwand der passive Plattenflügel 3 verriegelt werden. Durch den hakenförmigen Blockierabschnitt 12 ist ein einfaches Überdecken der korrespondierenden Kante des passiven Plattenflügels 3 möglich, was ein Blockieren der Bewegung der Plattenflügel 2,3 durch Verklemmen von Bauteilen oder eine nicht gerade Ausrichtung der beiden Plattenflügel 2,3 in Gebrauchsstellung verhindert.Due to the mutual locking of the plate wings 2.3, the passive plate wings 3 can be locked without much effort. Through the hooked blocking section 12 it is possible to simply cover the corresponding edge of the passive panel wing 3, which prevents the movement of the panel wing 2.3 from being blocked by jamming of components or an incorrect alignment of the two panel wing 2.3 in the position of use.

In den Figuren 6 und 7 ist die Ausgestaltung der Erfindung gemäß der Figuren 1 bis 5 nochmals in zwei weiteren Ansichten dargestellt.In the Figures 6 and 7 is the embodiment of the invention according to Figures 1 to 5 shown again in two further views.

Figur 6 zeigt den Zustand, bei dem die Plattenflügel 2,3 heruntergeklappt sind. Zu erkennen ist hier, dass die Halteraste 11 in diesem Zustand frei von dem Gelenkadapter 5 absteht, in zusammengeklapptem Zustand der Plattenflügel 2,3 also funktionslos ist. Ferner ist zu erkennen, dass das Bedienmittel 4, getrieben durch die Federmittel 10, wieder in die Ausgangsposition zurückgefedert ist. figure 6 shows the state in which the panel wings are folded down 2.3. It can be seen here that the retaining catch 11 protrudes freely from the articulated adapter 5 in this state, so that the plate wings 2, 3 are inoperative in the folded state. It can also be seen that the operating means 4, driven by the spring means 10, springs back into the starting position.

Figur 7 zeigt eine Explosionsdarstellung der wesentlichen Bauteile der erfindungsgemäßen Wischplatte. Hier sind insbesondere die Anordnung des Federmittels 10, der Blockierabschnitt 12 sowie die Lagerung der beiden Plattenflügel 2, 3 um die erste Schwenkachse 7 und die zweite Schwenkachse 8 zu erkennen. figure 7 shows an exploded view of the essential components of the wiper plate according to the invention.

    • latching means for automatically locking the fixable plate wing (2) when transferred to a position of use in which the bottom sides of the fixable plate wing (2) and the passive plate wing (3) lie in one plane, and comprising
    • a user-operable actuating means (4) for releasing the latching means, wherein
    the fixable plate wing (2) fixes the passive plate wing (3) in the position of use and releases it as a result of its pivoting after the latching means have been released, wherein
    the latching means being arranged on the hinged adapter (5) on the one hand and on the fixable plate wing (2) on the other hand, wherein the latching means being arranged at least on one side of the latching connection on a structural member which is elastically deformable at least in sections or on a laterally displaceable structural member which is supported slidably on the hinged adapter (5) and the actuating means (4) can be urged against the elastically deformable structural member by means of a pressure section (9), which is capable of displacing an elastically deformable or displaceable section of the structural member in such a way that the latching means are disengaged and the fixable plate wing (2) is released.
  2. Foldable wiper plate according to claim 1, characterized in that the latching means are constituted by at least one retaining latch (11) and at least one latching edge (13) which engages behind the retaining latch (11) in the position of use, the retaining latch (11) and/or the latching edge (13) being arranged on the elastically deformable or displaceable structural member.
  3. Foldable wiper plate according to claim 2, characterized in that the fixable plate wing (2) fixes the passive plate wing (3) in the position of use by means of a blocking section (12) projecting into the pivoting range of the passive plate wing (3) and forming a panel lock, and after release and as a result of pivoting of the fixable plate wing (2) the blocking section (12) is moved out of the pivoting range and the panel lock is cancelled.
  4. Foldable wiper plate according to one of the two preceding claims, characterized in that the elastically deformable structural member is the hinged adapter (5) or is arranged on the hinged adapter (5), wherein in particular a portion of a wall of the hinged adapter (5) facing the fixable plate wing (2) is elastically deformable to form the elastic zone of the structural member.
  5. The foldable wiper plate according to claim 4, characterized in that said hinged adapter (5) comprises, on the side of said fixable plate wing (2), a spring tongue embodied in particular by two opposite vertical slots and a free lower end which constitutes the elastic zone and on which the retaining latch (11) is arranged in the form of a protruding, in particular nose-shaped, pressure-receiving abutment zone which, when the actuating means (4) is actuated, comes into contact with the pressure zone (9) and is displaced by the latter, pressing in and releasing the latching edge (13).
  6. Foldable wiper plate according to claim 4 or 5, characterized in that the actuating means (4) are constituted by a foot pedal supported movably, in particular rotatably or pivotably, on the fixable plate wing (2), wherein the pressure section (9), upon movement of the foot pedal in the direction of a plate-side stop, initially comes into contact with the elastically deformable structural member and subsequently displaces and/or deforms the latter to a sufficient extent that the retaining latch (11) and the latching edge (13) for releasing the fixable plate wing (2) disengage.
  7. Foldable wiper plate according to claim 2 or 3, characterized in that the elastically deformable structural member is the fixable plate wing (2) or is arranged on the fixable plate wing (2).
