  • the use of the particular embodiment of the Velcro elements with the flattened head area has the additional advantage that damage to the surface to be cleaned can be avoided, since even with very thin cleaning surface, especially for example in the form of antistatic cloths, the Velcro elements no longer with pointed end portions can come into contact with the surface, which so far with conventional Velcro fasteners and thin cleaning pads the risk of scratches brought with it. Also, the installation of the cleaning device without cleaning surface could lead to scratches or an unwanted hooking with, for example, textile floor coverings. Since the holding elements are movably mounted, they can move upwards on a sensitive surface when setting up the carrier plate and will not exert any critical pressure force on the surface.

Description

Die Erfindung betrifft ein Reinigungsgerät nach dem Oberbegriff des Anspruchs 1. Das gattungsgemäße Reinigungsgerät weist insbesondere eine Trägerplatte mit einer Arbeitsfläche auf, die an die zu reinigenden Fläche angelegt werden kann. Dabei kann eine mögliche Anwendung die Ausbildung des Reinigungsgerätes als Bodenwischer sein, jedoch ist die Erfindung hierauf nicht beschränkt. Auch in Verbindung mit in der Hand gehaltenen, zum Beispiel als Fliesen- oder Tischwischer ausgebildeten Geräten, Einwäschern oder Abziehern für Fenster, Besen oder Kehrgeräten oder auch in Verbindung mit Polier- oder Schleifgeräten kann die Erfindung genutzt werden. Alle diese Vorrichtungen werden nachfolgend vereinfacht als Reinigungsgerät bezeichnet.The invention relates to a cleaning device according to the preamble of claim 1. The generic cleaning device has in particular a support plate with a working surface which can be applied to the surface to be cleaned. In this case, a possible application may be the design of the cleaning device as a floor wiper, however, the invention is not limited thereto. Also in connection with hand-held, trained as a tile or table wiper devices, Einwäschern or pullers for windows, brooms or sweepers or in conjunction with polishing or grinding equipment, the invention can be used. All these devices are hereinafter referred to simply as a cleaning device.

An dem Reinigungsgerät, bevorzugt an der Trägerplatte, kann ein Reinigungsbelag, zum Beispiel in Form eines Tuchs, eines Schwamms, einer Schleiffläche oder eines Kehransatzes, über eine Klettverbindung derart befestigt werden, dass der Reinigungsbelag an der, der zu reinigenden Fläche zugewandten Arbeitsfläche gehalten ist. Dafür ist zumindest ein Halteelement vorgesehen, das eine mit Kletthaken versehende Klettfläche zur Befestigung des Reinigungsbelags aufweist.On the cleaning device, preferably on the support plate, a cleaning pad, for example in the form of a cloth, a sponge, a grinding surface or a Kehransatzes be attached via a Velcro connection such that the cleaning pad is held on the, the surface to be cleaned facing working surface , For this purpose, at least one holding element is provided, which has a Velcro hook with Velcro surface for attachment of the cleaning pad.

Ein Wischtuch zur Befestigung an einem Reinigungsgerät dieser Art ist aus der DE 10 2010 03 568 A1 bekannt. Dieses Wischtuch wird über eine Klettverbindung mit der Unterseite eines Mopphalters verbunden und ist mehrlagig ausgebildet. Es weist eine obere, flüssigkeitsspeichernde Lage auf, auf der mittelbar oder unmittelbar ein klettfähiger Befestigungsstreifen angeordnet ist, über den das Wischtuch an der Unterseite einer Trägerplatte des Reinigungsgerätes befestigt werden kann.A wiper for attachment to a cleaning device of this kind is from the DE 10 2010 03 568 A1 known. This wipe is connected via a Velcro connection to the underside of a mop holder and is multi-layered. It has an upper, liquid-storing layer on which a klettfähiger mounting strip is arranged directly or indirectly, via which the wipe can be attached to the underside of a support plate of the cleaning device.

Das Wischtuch kann zwar gut durchfeuchtet werden, da es die flüssigkeitsspeichernde Lage aufweist und bei Verwendung in Verbindung mit einem geeigneten Reinigungsgerät unmittelbar unter dem Feuchtigkeit abgebenden Befeuchtungsverteiler liegen würde, jedoch ist die Befestigung des Wischtuches über die Klettverbindung nicht optimal, da die Haltekräfte der Klettverbindung eine vergleichsweise große Klettfläche aufweisen.Although the wipe can be well moistened, as it has the liquid-storing layer and when used in conjunction with a suitable Cleaning device would lie directly under the moisturizing moistening, but the attachment of the wipe on the Velcro connection is not optimal, since the holding forces of the Velcro connection have a relatively large Velcro surface.

Eine Befestigung der Reinigungsborsten einer Waschbürste über eine herkömmliche Klettverbindung ist aus der DE 103 35 373 B3 bekannt. Ein über eine lösbare Verbindung mit der Wischplatte eines Wischgerätes verbundene Reinigungslage ist aus der WO 03/000104 A1 bekannt. Eine ähnliche Lösung zeigt die US 5 607 345 A für eine Schleifplatte.An attachment of the cleaning bristles of a washing brush via a conventional Velcro connection is from the DE 103 35 373 B3 known. A connected via a releasable connection with the mop plate of a wiper cleaning device is known from WO 03/000104 A1 known. A similar solution shows the US 5,607,345 A for a sanding plate.

Ein Wischgerät mit beweglichen Klettflächen ist aus der US 2013/0340187 A1 bekannt. Hierbei werden in der Wischplatte beweglich gelagerte Träger für Klettflächen von dem Wischtuch in Querrichtung weggezogen, wobei hierdurch das Wischtuch von den Klettflächen abgerissen wird. Dies hat aber den Nachteil, dass die Gefahr besteht, dass das Wischtuch in die Öffnungen der Klettflächen hineingezogen wird und ferner durch die hohen Zugkräfte beschädigt wird.A wiper device with movable Velcro surfaces is from the US 2013/0340187 A1 known. Here, in the wiper plate, movably mounted carriers for hook and loop areas are pulled away from the wipe in the transverse direction, whereby the wipe is thereby torn off the hook and loop surfaces. But this has the disadvantage that there is a risk that the wipe is pulled into the openings of the Velcro and also damaged by the high tensile forces.

Ein Wischtuch, das über eine sogenannte Pilzkopf-Klettverbindung mit der Wischplatte verbunden ist, ist aus der US 5607345 A1 bekannt. Diese Verbindung ist zwar fest, hat aber den Nachteil, dass die Gefahr der Beschädigung bei unsachgemäßem Abziehen des Wischtuchs in der eher naheliegenden, zur Wischplatte senkrechten Richtung besteht.A wiper, which is connected via a so-called mushroom hook and loop connection with the mop plate, is from the US 5607345 A1 known. Although this connection is firm, but has the disadvantage that the risk of damage in improper removal of the wipe in the more obvious, perpendicular to the mop plate direction.

Aufgabe der Erfindung ist es daher, ein Reinigungsgerät zu schaffen, bei dem die Befestigung über die Klettverbindung eine höhere Festigkeit aufweist und kleinere Klettflächen möglich sind.The object of the invention is therefore to provide a cleaning device in which the attachment via the Velcro connection has a higher strength and smaller Velcro surfaces are possible.

Diese Aufgabe wird nach der Erfindung durch ein Reinigungsgerät nach Anspruch 1 gelöst. Das erfindungsgemäße Reinigungsgerät ist dabei bevorzugt dadurch charakterisiert, dass die Klettfläche mit den Kletthaken relativ zur Arbeitsfläche beweglich ist und die Kletthaken einen, sich von der Klettfläche aus erstreckenden stiftartigen Schaft und am freien Ende des Schaftes einen sich in zumindest eine Querrichtung erstreckenden Kopfbereich aufweisen, wobei die relativ zur Arbeitsfläche bewegliche Klettfläche derart beweglich ist, dass die Klettelemente zumindest in einem von der Senkrechten auf die Arbeitsfläche unterschiedlichen Winkel, bevorzugt aber zusätzlich auch in die zur Arbeitsfläche senkrechte Richtung bewegt sind.This object is achieved according to the invention by a cleaning device according to claim 1. The cleaning device according to the invention is preferably characterized in that the Velcro surface with the Velcro hooks is movable relative to the work surface and the Velcro hooks have a, from the Velcro surface extending pin-like shaft and at the free end of the shaft in at least one transverse direction extending head portion, wherein the movable relative to the work surface Velcro surface is movable such that the Velcro elements at least in one of the perpendicular to the work surface different angles, but preferably also in the direction perpendicular to the work surface direction are moved.

Der sichere Halt des Reinigungsbelags an der Trägerplatte wird über die besondere Ausgestaltung der Klettverbindung realisiert. Diese Klettverbindung weist Kletthaken auf, die einen unteren, stiftartigen Schaft aufweisen, mit dem sie an dem Halteelement bzw. an den Halteelementen befestigt sind. Dies kann über eine übliche Klebeverbindung erfolgen, insoweit unterscheidet sich die Klettfläche nicht notwendigerweise von den klassischen Klettverschlüssen.The secure hold of the cleaning pad on the support plate is realized on the particular configuration of the Velcro connection. This hook-and-loop connection has hooked hooks which have a lower, pin-like shaft with which they are fastened to the retaining element or to the retaining elements. This can be done via a conventional adhesive joint, in this respect, the Velcro surface does not necessarily differ from the classic Velcro fasteners.

Am oberen Ende des stiftartigen Schaft es ist jedoch im Gegensatz zu den üblichen Klettverbindungen nicht nur ein reiner Hakenbereich vorgesehen, der sich mit einem textilen Belag verhaken kann, sondern die Kletthaken weisen in diesem Bereich einen sich nach außen erstreckenden Kopfbereich auf, der in zumindest eine Querrichtung nach außen ragt.At the upper end of the pin-like shaft, however, in contrast to the usual Velcro not only a pure hook area is provided which can get caught with a textile covering, but the Velcro hooks have in this area an outwardly extending head portion in at least one Transverse direction protrudes outwards.

Bevorzugt wird der Kopfbereich allerdings in mehrere oder alle Richtungen nach außen ragen, so dass er zum Beispiel die Form eines kleinen Pilzes aufweisen kann. Dabei können die Kopfbereiche nicht nur pilzkopf- oder tellerförmig, sondern auch L-förmig oder T-förmig sein oder auch jede andere Form aufweisen, die einen seitlichen, vorzugsweise in zumindest eine der zum Schaft senkrechten Richtungen verlaufenden Fortsatz aufweisen. Eine solche Klettverbindung ist auch unter dem Namen Pilzkopf-Klettverbindung bekannt und wird zum Beispiel unter dem Markennamen 3M DualLock von der Firma 3M Deutschland GmbH vertrieben.Preferably, however, the head region will protrude outward in several or all directions so that it may, for example, have the shape of a small mushroom. The head regions may be not only mushroom-shaped or plate-shaped, but also L-shaped or T-shaped or also have any other shape which has a lateral extension, preferably extending in at least one of the directions perpendicular to the shaft. Such a Velcro connection is also known under the name mushroom hook and loop fastener and is sold, for example, under the brand name 3M DualLock by the company 3M Germany GmbH.

Aus Sicht der Arbeitsfläche bzw. des Schaftes der Klettelemente findet nun eine Relativbewegung in Querrichtung zur Arbeitsfläche bzw. zum Schaft und optional auch in Längsrichtung des Schaftes statt. Zur Befestigung des Reinigungsbelags weist dieser eine klettfähige Fläche auf, die im Bereich der Klettflächen liegt. Dies kann das Material des Reinigungsbelags selbst sein, beispielsweise im Falle eines Reinigungstextils oder eines Fasergewirks oder filzes. Bei anderen Reinigungsbelägen kann, wie bei herkömmlichen Klettverbindungen, ein klettfähiger Aufkleber oder sonstiger Belag gewählt werden.From the point of view of the working surface or of the shank of the Velcro elements, there is now a relative movement in the transverse direction to the working surface or to the shank and optionally also in the longitudinal direction of the shank. To attach the cleaning pad this has a velcro-compatible surface, which lies in the area of the Velcro surfaces. This may be the material of the cleaning pad itself, for example in the case of a cleaning fabric or a Fasergewirks or felt. For other cleaning surfaces, as with conventional Velcro, a velcro sticker or other flooring can be selected.

Die relative Bewegung zwischen Klettelementen und Reinigungsbelag ermöglicht den Kopfbereichen der Klettelemente in die Schlaufen des klettfähigen Textils einzugreifen und Fasern unterhakend zu untergreifen. Durch das Unterhaken wird leicht und effektiv die Verbindung hergestellt. Dabei sind nur geringfügige Relativbewegungen zwischen den Klettelementen und dem Reinigungsbelag erforderlich. Üblicherweise wird der Kopfbereich um weniger als 1mm von Schaft hervorragen, so dass eine Relativbewegung von wenigen Millimetern ausreichend sein wird, um den Einhakeffekt zu erreichen.The relative movement between Velcro and cleaning pad allows the head portions of the Velcro elements to intervene in the loops of Velcro textile and unterhakend underneath hooking fibers. The under hooks make the connection easy and effective. Only minor relative movements between the Velcro elements and the cleaning pad are required. Usually, the head area will protrude from the shaft by less than 1mm so that a relative movement of a few millimeters will be sufficient to achieve the hooking effect.

Das Reinigungsgerät soll mit einer sicheren Befestigung zwischen dem Reinigungsbelag und der Trägerplatte versehen sein oder bzw. zusätzlich soll die Befestigung über einen kleiner gehaltenen Klettverschluss möglich werden. Optional soll der Benutzer in die Lage versetzt werden, den Reinigungsbelag fernbetätigt von der Trägerplatte lösen zu können. Dies kann über einen separaten Betätigungsmechanismus oder über eine geeignete Ausgestaltung der Trägerplatte selbst folgen, wie nachfolgend noch ausführlich beschrieben werden wird.The cleaning device should be provided with a secure attachment between the cleaning pad and the support plate or or additionally, the attachment should be possible via a small held Velcro. Optionally, the user should be enabled to remotely release the cleaning pad from the carrier plate. This can be followed by a separate actuating mechanism or by a suitable embodiment of the carrier plate itself, as will be described in detail below.

Die im Zusammenhang mit der vorliegenden Erfindung benutzten Klettverbindungen haben den Vorteil, dass sie in senkrechter Richtung zum Reinigungsbelag einen erhöhten Schutz gegen Abziehen bieten. Gleichzeitig haben sie aber auch den weiteren Vorteil, dass sie bei einer Bewegung der über sie verbundenen Teile in Querrichtung vergleichsweise leichter lösbar sind. Dieser Effekt wird erfindungsgemäß nun ausgenutzt, um das Befestigen des Reinigungsbelags an der Trägerplatte zu optimieren.The hook and loop fasteners used in connection with the present invention have the advantage that they provide increased protection against peeling in the direction perpendicular to the cleaning pad. At the same time, however, they also have the further advantage that they are relatively easier to detach in a transverse movement when the parts connected via them are moved. This effect is now utilized according to the invention to optimize the attachment of the cleaning pad to the carrier plate.

Der für das Unterhaken genutzten Bewegung in eine Querrichtung kann zusätzlich auch eine Bewegung in eine zur Arbeitsfläche senkrechte Richtung überlagert oder zeitlich nach- oder vorgeschaltet sein kann. Dies kann über eine Längsbewegung oder eine Drehbewegung in einer gewindeartigen Schraubführung erfolgen, alternativ können die Kletthaken auch an Halteelementen angeordnet sein, die schräg, zum Beispiel längs von schiefen Ebenen geführt sind, so dass sie sich beim Eindrücken in die Trägerplatte nicht nur in Richtung der Trägerplatte sondern auch quer zur Trägerplatte bewegen.The movement used in a transverse direction for the lower hook can additionally be superimposed on a movement in a direction perpendicular to the working surface or can be followed or connected upstream in time. This can be done via a longitudinal movement or a rotational movement in a thread-like screw, alternatively, the Velcro hooks can also be arranged on holding elements which are obliquely, for example, guided along oblique planes, so that they not only in the direction of the But also move the carrier plate transversely to the carrier plate.

Die Trägerplatte weist zum Befestigen des Reinigungsbelags die Halteelemente auf. Diese Halteelemente sind an ihrer Unterseite mit der Klettfläche versehen, wobei die Halteelemente so neben oder in der Trägerplatte angeordnet sind, dass sie um eine bevorzugt eher kleine Strecke aus der Ebene herausspringen. Somit ragen wenigsten die als Hakenbereiche der Klettelemente benutzen Kopfbereich aus der Ebene der Arbeitsfläche heraus.The support plate has for attaching the cleaning pad on the holding elements. These holding elements are provided on their underside with the Velcro surface, wherein the holding elements are arranged next to or in the carrier plate so that they jump out of the plane by a preferably rather small distance. Thus, at least the head area used as hook areas of the hook and loop elements project out of the plane of the work surface.

Durch die besondere Ausgestaltung kann die Trägerplatte nun auf einen klettfähigen Reinigungsbelag, zum Beispiel auf ein Wischtuch, aufgesetzt werden, wobei sich die geringfügig nach unten herausragenden Klettelemente mit dem Material des Reinigungsbelages dadurch verbinden, dass die Klettelemente nach oben gedrückt werden und sich dabei seitlich verlagern oder drehen. Hierdurch verhakt sich dann die Klettverbindung. Dies kann durch die Druckkraft des Benutzers oder auch nur durch das Gewicht des Reinigungsgerätes erfolgen, das zum Beispiel ausreichend sein kann, die drehbar oder in seitlicher Richtung verschiebbar gelagerten Halteelemente in der Lagerung zu bewegen.Due to the particular configuration, the support plate can now be placed on a velcro-cleaning surface, for example, on a wipe, with the slightly downwardly projecting hook and loop fasteners connect with the material of the cleaning lining in that the hook and loop elements are pushed up and move laterally or turn. As a result, then hooked the Velcro connection. This can be done by the pressure force of the user or even by the weight of the cleaning device, which may be sufficient, for example, to move the rotatable or laterally slidably mounted holding elements in the storage.

Grundsätzlich kann zur Umsetzung der Erfindung bereits das Vorsehen eines einzelnen Halteelementes ausreichend sein. Dieses kann beispielsweise, ähnlich wie die rahmenartige Bürste der Düse eines Bodenstaubsaugers, um die Trägerplatte herum verlaufen und so den Rand des Reinigungsbelags vollständig erfassen. Ein vollständiges, umfängliches Erfassen des Randes ist jedoch auch nicht immer notwendig, es kann auch ausreichend sein, nur einen Rand des Reinigungsbelags mit der Trägerplatte zu verbinden, so dass der dahinterliegende Bereich des Reinigungsbelags beispielsweise hinter der Verbindung hergezogen werden kann.In principle, the provision of a single retaining element may be sufficient to implement the invention. This can, for example, similar to the frame-like brush of the nozzle of a vacuum cleaner, run around the support plate around and so completely grasp the edge of the cleaning pad. However, a complete, peripheral detection of the edge is not always necessary, it may also be sufficient to connect only one edge of the cleaning pad to the carrier plate, so that the underlying area of the cleaning pad can be pulled behind the connection, for example.

Eine bevorzugte Ausgestaltung der Erfindung weist jedoch mehrere Halteelemente auf, die an unterschiedlichen Stellen den Reinigungsbelag an der Trägerplatte halten. Diese Halteelemente sind beispielsweise über die Unterseite der Trägerplatte verteilt, so dass der Reinigungsbelag, ohne dass er bei Anheben der Trägerplatte herunter hängen würde, an der Unterseite der Trägerplatte gehalten ist.However, a preferred embodiment of the invention has a plurality of holding elements that hold the cleaning pad on the support plate at different locations. These holding elements are for example distributed over the underside of the carrier plate, so that the cleaning pad, without it would hang down when lifting the carrier plate, is held on the underside of the carrier plate.

Zusätzlich zum Greifen des Reinigungsbelags kann die Erfindung ausgenutzt werden, um den Reinigungsbelag wieder zu lösen. Hierzu kann das Halteelement noch weiter in die Trägerplatte eingezogen werden, so dass im Bereich der Klettverbindung Scherkräfte auftreten, die die Klettverbindung lösen. Dadurch, dass die Halteelemente an der Unterseite angeordnet sind, ist es besonders einfach, den Reinigungsbelag nach Lösen der Klettverbindung beispielsweise in einen Entsorgungsbehälter fallen zu lassen. Das Einziehen der Halteelemente kann durch Aufsetzen der Trägerplatte auf ein Widerlager, beispielsweise den Rand oder einen Absatz des Abfallbehälters, oder über eine vom Benutzer bedienbare Betätigungsvorrichtung erfolgen.In addition to gripping the cleaning pad, the invention can be exploited to solve the cleaning pad again. For this purpose, the holding element can be further retracted into the carrier plate, so that in the region of the Velcro connection Shearing forces occur that solve the Velcro connection. The fact that the holding elements are arranged on the underside, it is particularly easy to drop the cleaning pad after loosening the Velcro connection, for example, in a disposal container. The retraction of the holding elements can be done by placing the support plate on an abutment, such as the edge or a shoulder of the waste container, or via a user-operable actuator.

Bevorzugt wird ein bewegliches Trägerelement an der Trägerplatte vorgesehen sein, von dem aus sich die Halteelemente mit den Klettbereich nach unten durch Ausnehmungen in der Arbeitsfläche erstrecken. Der Spalt zwischen der Arbeitsfläche und den Halteelementen ist dann im Falle eines textilen oder sonstigen, flexiblen Reinigungsbelags so klein, dass ein Einziehen des Reinigungsbelags in die Ausnehmungen nicht auftritt, wobei dies erst dadurch möglich wird, dass die erfindungsgemäßen Klettverbindungen wegen der besonderen Form der Klettelemente sehr klein gehalten werden können.Preferably, a movable support member will be provided on the support plate, from which extend the holding elements with the Velcro down through recesses in the work surface. The gap between the work surface and the support members is then so small in the case of a textile or other flexible cleaning pad that retraction of the cleaning pad does not occur in the recesses, this being possible only in that the Velcro connections according to the invention because of the special shape of the Velcro elements can be kept very small.

Nachfolgend wird die Erfindung in Verbindung mit mehreren, nebeneinander in der Unterseite der Trägerplatte vorgesehenen Halteelementen im Detail beschrieben, wobei diese natürlich ebenso gut neben den Seiten, insbesondere mit den Längsseiten der Trägerplatte vorgesehen sein könnten.In the following, the invention will be described in detail in connection with a plurality of holding elements provided side by side in the underside of the carrier plate, which of course could just as well be provided next to the sides, in particular with the longitudinal sides of the carrier plate.

Die Querbewegung der Kletthaken wird bevorzugt dadurch realisiert, dass die Halteelemente in einer gewindeartigen Schneckenführung gelagert sind, so dass sich durch diese Schraublagerung nicht nur die Bewegung senkrecht zur Trägerplatte, sondern auch in die Querrichtung ergibt, da ein Eindrücken der Halteelemente in die Schraublagerung selbsttätig zu deren Verdrehen und damit zu einer Querbewegung nicht konzentrisch zur Drehachse liegenden Klettelemente führt.The transverse movement of the hooks is preferably realized in that the holding elements are mounted in a thread-like screw, so that not only the movement perpendicular to the support plate, but also in the transverse direction results from this Schraublagerung, as a depression of the holding elements in the Schraublagerung automatically their rotation and thus to a transverse movement is not concentric with the axis of rotation Velcro leads.

Das Verdrehen der Halteelemente in der Schraublagerung wird zunächst genutzt, um den Reinigungsbelag mit den Klettelementen zu verhaken. Hierzu stellt der Benutzer einfach die Trägerplatte auf den Reinigungsbelag auf bzw. drückt die Trägerplatte bei Handgeräten auf den Reinigungsbelag. Durch die Gewichtskraft oder die Druckkraft können nun die ursprünglich aus der Ebene der Unterseite der Trägerplatte leicht herausragenden Halteelemente nach innen, in die Trägerplatte hineingedrückt werden. Da gleichzeitig durch die Führung der Halteelemente in der, in der Trägerplatte vorgesehen Lagerung deren Querbewegung realisiert wird, verhaken sich die Kopfbereiche der Klettelemente mit der Oberseite des Reinigungsbelags.The twisting of the retaining elements in the Schraublagerung is initially used to hook the cleaning pad with the Velcro elements. For this purpose, the user simply sets the support plate on the cleaning pad or pushes the support plate in handheld devices on the cleaning pad. By the force of gravity or the compressive force, the holding elements, which are now slightly protruding from the plane of the underside of the carrier plate, can now be pressed inwards into the carrier plate become. Since at the same time by the leadership of the holding elements in the, provided in the support plate storage their transverse movement is realized, the head portions of the Velcro hooked to the top of the cleaning pad.

Die Verwendung der besonderen Ausgestaltung der Klettelemente mit dem abgeflachten Kopfbereich hat den zusätzlichen Vorteil, dass eine Beschädigung der zu reinigenden Oberfläche vermieden werden kann, da auch bei sehr dünnem Reinigungsbelag, insbesondere zum Beispiel in Form von antistatischen Tüchern, die Klettelemente nicht mehr mit spitzen Endbereichen in Kontakt mit der Fläche kommen können, was bei klassischen Klettverbindungen und dünnen Reinigungsbelägen bisher die Gefahr von Kratzern mit sich brachte. Auch konnte das Aufstellen des Reinigungsgerätes ohne Reinigungsbelag zu Kratzern oder einem ungewollten Verhaken mit zum Beispiel textilen Bodenbelägen führen. Da nun die Halteelemente beweglich gelagert sind, können sie bei Aufstellen der Trägerplatte auf eine empfindliche Oberfläche nach oben ausweichen und werden keine kritische Druckkraft auf die Oberfläche ausüben.The use of the particular embodiment of the Velcro elements with the flattened head area has the additional advantage that damage to the surface to be cleaned can be avoided, since even with very thin cleaning surface, especially for example in the form of antistatic cloths, the Velcro elements no longer with pointed end portions can come into contact with the surface, which so far with conventional Velcro fasteners and thin cleaning pads the risk of scratches brought with it. Also, the installation of the cleaning device without cleaning surface could lead to scratches or an unwanted hooking with, for example, textile floor coverings. Since the holding elements are movably mounted, they can move upwards on a sensitive surface when setting up the carrier plate and will not exert any critical pressure force on the surface.

Während der Benutzung des erfindungsgemäßen Reinigungsgerätes wird nun die Klettverbindung weiter fest bleiben, da eine weitere Bewegung der Halteelemente nach Eindrücken in die Lagerung in der Trägerplatte nicht mehr erfolgt. Zum Lösen des Reinigungsbelags können nun die Halteelemente wieder aus der Lagerung heraus derart bewegt werden, dass sie aus der Ebene der Unterseite der Trägerplatte wieder heraus stehen, also ihre Anfangsposition wieder einnehmen. Dies kann beispielsweise durch reine Schwerkraft erfolgen, wenn die Trägerplatte nicht mehr auf einer zu reinigenden Fläche aufsteht. Alternativ kann allerdings auch sowohl für die Befestigungsbewegung als auch für die Lösebewegung eine manuell vom Benutzer zu bedienende Betätigungsvorrichtung vorgesehen sein. Diese Betätigungsvorrichtung kann beispielsweise ein Seilzug sein, der es ermöglicht, die Halteelemente relativ zum übrigen Bereich der Trägerplatte in die gewünschte Richtung zu bewegen.During use of the cleaning device according to the invention, the Velcro connection will now remain firmly fixed, since further movement of the holding elements after pressing into the storage in the carrier plate no longer takes place. To release the cleaning pad, the holding elements can now be moved out of the storage again so that they stand out of the plane of the underside of the carrier plate out again, so take their initial position again. This can be done for example by pure gravity when the support plate no longer stands up on a surface to be cleaned. Alternatively, however, can be provided for both the fastening movement and for the release movement manually operated by the user operating device. This actuating device can be, for example, a cable pull, which makes it possible to move the holding elements relative to the remaining area of the carrier plate in the desired direction.

Eine mögliche Ausgestaltung der Erfindung kann beispielsweise ein Bodenwischer sein, dessen Trägerplatte ein inneres Trägerelement aufweist, an dem die Halteelemente befestigt sind. Dieses innere Trägerelement kann dann im übrigen Bereich der Trägerplatte verschiebbar gelagert sein, wobei die Unterseite der Trägerplatte Ausnehmungen aufweist, durch die die Halteelemente mit den Klettbereichen hindurch ragen.A possible embodiment of the invention may be, for example, a floor wiper, the support plate has an inner support member to which the holding elements are attached. This inner support member may then be slidably mounted in the remaining region of the support plate, wherein the underside of the support plate Having recesses through which protrude the holding elements with the Velcro areas.

Das Trägerelement kann bei dieser Ausgestaltung beispielsweise durch Aufsetzen auf einen Boden nach oben verlagert werden, wobei die drehbar an den Trägerelement gelagerten Halteelemente in einer Schraubführung an der Unterseite der Trägerplatte gelagert sind, sich also nicht nur zusammen mit den Trägerelement nach oben verlagern, sondern sich gleichzeitig auch zwangsweise drehen. Durch diese anfängliche Drehbewegung wird der Kontaktbereich mit dem Reinigungsbelag fest mit den Klettelementen verbunden. Hierzu sind nur eine geringfügige Verlagerung der Halteelemente und eine kleine Drehbewegung notwendig.The support member can be moved in this embodiment, for example, by placing it on a floor upwards, wherein the rotatably mounted on the support member retaining elements are mounted in a screw on the underside of the support plate, so not only move together with the support member up, but themselves simultaneously forcibly turn. By this initial rotational movement of the contact area with the cleaning pad is firmly connected to the Velcro elements. For this purpose, only a slight displacement of the holding elements and a small rotational movement are necessary.

Zum Befestigen des Reinigungsbelags stellt der Benutzer das Reinigungsberät mit der Trägerplatte auf den Reinigungsbelag. Dadurch verlagern sich die Halteelemente und die Klettelemente haken mit den Kopfbereichen in die Oberfläche des korrespondierenden Bereichs des Reinigungsbelags ein.To attach the cleaning pad, the user places the cleaning advisor with the carrier plate on the cleaning pad. As a result, the retaining elements and the Velcro elements hook with the head areas in the surface of the corresponding region of the cleaning pad.

Zum Lösen oder zumindest zum Erleichtern des Lösens kann der Benutzer nun das Reinigungsgerät anheben, so dass durch die Schwerkraft das Trägerelement wieder absinkt und die drehbar gelagerten und geführten Halteelemente in die gegensinnige Richtung gedreht werden und wieder aus der Ebene der Unterseite der Trägerplatte heraustreten. Hierdurch kann die Klettverbindung gelöst und der benutzte Reinigungsbelag nach unten herabfallen lassen werden. Alternativ zu dieser reinen, durch den Druck des Aufstellens auf die zu reinigenden Fläche und die Schwerkraft getriebenen Lösung sind weitere Ausgestaltungen möglich.To release or at least to facilitate the release of the user can now raise the cleaning device, so that by gravity, the support element drops again and the rotatably mounted and guided holding elements are rotated in the opposite direction and again emerge from the plane of the bottom of the support plate. As a result, the Velcro connection can be solved and let the used cleaning pad fall down. As an alternative to this pure, driven by the pressure of positioning on the surface to be cleaned and gravity driven further embodiments are possible.

So kann beispielsweise eine Rastvorrichtung vorgesehen sein, die die Halteelemente oder, sofern vorhanden, die Trägerplatte im eingedrückten Zustand verrasten. Dies hat den Vorteil, dass der Benutzer das Reinigungsgerät anheben kann, ohne dass die Gefahr besteht, dass der Reinigungsbelag ungewollt herunterfällt. Dies erleichtert das Umsetzen des Reinigungsgerätes und verhindert das nicht beabsichtigte Herabfallen des noch nicht verbrauchten Reinigungsbelages.Thus, for example, a locking device may be provided, which lock the holding elements or, if present, the carrier plate in the depressed state. This has the advantage that the user can lift the cleaning device without the risk that the cleaning pad accidentally falls down. This facilitates the implementation of the cleaning device and prevents the unintended fall off of not yet used cleaning surface.

Zum Lösen des Reinigungsbelags von der Trägerplatte kann bei der oben beschriebenen Ausgestaltung die Verrastung über das Betätigungsmittel gelöst werden. Hierzu kann bei dem hier beschriebenen Bodenwischer beispielsweise an dem Stil ein Seilzug vorgesehen sein, der vom Benutzer über eine Handhabe gespannt werden kann und in der Trägerplatte die Verrastung löst. Nachfolgend kann das Trägerelement dann schwerkraftgetrieben wieder absinken. Weiterhin können zwischen den Halteelementen oder dem Trägerelement und den übrigen Bereichen der Trägerplatte auch Federn vorgesehen sein, die nach Lösen der Rastverbindung die Halteelemente bzw. das Trägerelement wieder in die Lösestellung zurück drücken.To release the cleaning pad from the support plate, the latching can be achieved via the actuating means in the embodiment described above. For this purpose, in the floor wiper described here, for example, a cable may be provided on the style, which can be tensioned by the user via a handle and releases the catch in the carrier plate. Subsequently, the support element can then drop gravity driven again. Furthermore, springs can also be provided between the holding elements or the carrier element and the remaining regions of the carrier plate, which press the holding elements or the carrier element back into the release position after releasing the latching connection.

Eine weitere Ausgestaltung der Erfindung löst die Klettverbindung dadurch, dass die Halteelemente noch weiter in die Trägerplatte eingezogen werden. Hierdurch entstehen an den Rändern der Ausnehmung, durch die die Halteelemente die Ebene der Unterseite der Trägerplatte durchdringen, Scherkräfte, die den Reinigungsbelag von den Halteelementen lösen können. Bei dieser Ausgestaltung können die Halteelemente so in der Trägerplatte gelagert sein, dass sie zunächst, wie oben beschrieben, in eine erste Verriegelungsrichtung verdreht werden.Another embodiment of the invention solves the Velcro connection in that the holding elements are further retracted into the carrier plate. This results in the edges of the recess through which the holding elements penetrate the plane of the underside of the support plate, shear forces that can solve the cleaning surface of the holding elements. In this embodiment, the holding elements may be mounted in the carrier plate so that they are first rotated, as described above, in a first locking direction.

Ein weiteres Hochziehen der Halteelemente kann dann eine Richtungsumkehr der Drehbewegung bewirken, wodurch die Verriegelung der Kopfbereiche der Klettverbindung aufgehoben wird, so dass zum einen der starke Halt der besonderen Klettverbindung und zum anderen durch die oben beschriebenen Scherkräfte der Reinigungsbelag von den Halteelementen gelöst wird. Die Richtungsumkehr Drehbewegung kann beispielsweise über ein gegensinniges Gewinde im oberen Bereich der Lagerung der Halteelemente realisiert werden. Die hierzu notwendige Bewegung der Halteelemente kann dann durch eine Betätigungsvorrichtung erfolgen, die zum Beispiel die an dem Trägerelement gelagerten Halteelemente hinreichend weit in die Lagerung hinein zu ziehen vermag.Further pulling up the holding elements can then cause a reversal of direction of the rotational movement, whereby the locking of the head portions of the Velcro connection is released, so that on the one hand the strong hold of the particular Velcro connection and on the other hand by the above-described shear forces of the cleaning pad is released from the holding elements. The direction reversal rotational movement can be realized for example via an opposite sense thread in the upper region of the mounting of the holding elements. The movement of the holding elements necessary for this purpose can then be effected by an actuating device which, for example, is capable of sufficiently pulling the holding elements mounted on the carrier element into the bearing.

Das Trägerelement kann durch die Kraft, die beim Andrücken der Trägerplatte auf die zu reinigenden Fläche ausgeübt wird, in die Trägerplatte hineingedrückt werden. Hier wird also dann die Betätigungskraft zur Bewegung der Halteelemente von diesen selbst auf das Trägerelement übertragen. Alternativ kann natürlich das Trägerelement auch separate Stützen aufweisen, die seitlich oder die Trägerplatte durchdringend vorgesehen sein können und eine Kraft von der zu reinigenden Fläche auf das Trägerelement übertragen. Diese können dann als Stellmittel genutzt werden, um das Trägerelement bei Anstellen bzw. Andrücken der Trägerplatte an die Fläche zu verlagern.The carrier element can be pressed into the carrier plate by the force which is exerted on the surface to be cleaned when the carrier plate is pressed on. Here, then, the actuating force is transmitted to the movement of the retaining elements of these themselves on the support element. Alternatively, of course, the support member may also have separate supports, which may be provided penetrating laterally or the support plate and transmit a force from the surface to be cleaned on the support member. These can then be used as adjusting means be to displace the support member when hiring or pressing the support plate to the surface.

Ferner ist es möglich, dass die Halteelemente durch Aufsetzen der Trägerplatte auf den Rand eines Abfallbehälters weiter in die Lösestellung verlagert werden. So kann zum Beispiel das oben beschriebene Trägerelement mit Stützbereichen nach außen aus der Trägerplatte herausragen, wobei die Geometrie an die Geometrie des Abfallbehälters angepasst ist, so dass sich bei Eintauchen der Trägerplatte in den Abfallbehälter eine Anlage der Stützbereiche an den Rand des Abfallbehälters ergibt. Dies kann dann dazu führen, dass die von den Stützbereichen übertragene Kraft das Trägerelement nach oben drückt, oder sich die Haltebereiche dann zum einen nochmals verdrehen und zum anderen vom Reinigungsbelag entfernen, was dann zur Lösung der Klettverbindung führt.Furthermore, it is possible that the retaining elements are displaced by placing the carrier plate on the edge of a waste container further in the release position. Thus, for example, the support element described above can protrude outward from the support plate with support regions, wherein the geometry is adapted to the geometry of the waste container, so that upon immersion of the support plate in the waste container results in a conditioning of the support areas to the edge of the waste container. This can then lead to the force transmitted by the support areas pushing the carrier element upwards, or the holding areas then turning on the one hand again and on the other hand removing from the cleaning coating, which then leads to the solution of the Velcro connection.

Bei einer möglichen Ausgestaltung der Erfindung ist das Reinigungsgerät als Bodenwischer ausgebildet. Hier ist es besonders günstig, wenn dieser Bodenwischer eine Befeuchtung des Reinigungsbelags ermöglicht. Diese kann insbesondere indirekt von oben erfolgen, wobei hierzu die Trägerplatte einen Befeuchtungsverteiler aufweisen kann, der Feuchtigkeit nach unten, in Richtung des dann als Wischtuch ausgebildeten Reinigungsbelags abzugeben vermag.In one possible embodiment of the invention, the cleaning device is designed as a floor wiper. Here it is particularly advantageous if this floor wiper allows humidification of the cleaning pad. This can in particular be done indirectly from above, for which purpose the carrier plate may have a moistening distributor, which is able to dispense moisture downwards in the direction of the cleaning pad then formed as a wiping cloth.

Das Wischtuch ist bei dieser Ausgestaltung so ausgebildet, dass es sich einerseits eignet, mit der besonderen Klettverbindung zusammenzuwirken. Andererseits muss es in der Lage sein, die bereitgestellte Feuchtigkeit entweder zur zu reinigenden Fläche zu transportieren oder im Falle einer weiteren bevorzugten Ausgestaltung auch zu bevorraten, also zu speichern. Hierzu kann das Wischtuch mehrlagig ausgebildet sein, wobei eine mittlere Lage als feuchtigkeitsspeichernde Lage dient. Die Reinigungslage ist unterhalb dieser feuchtigkeitsspeichernden Lage vorgesehen und weist die notwendigen Eigenschaften auf, um beispielsweise Schmutz abkratzen zu können oder auch schonend die Oberfläche zu reinigen.The wiper is formed in this embodiment so that on the one hand it is suitable to cooperate with the special Velcro connection. On the other hand, it must be able to transport the moisture provided either to the surface to be cleaned or, in the case of a further preferred embodiment, also to store it, that is to store it. For this purpose, the wipe can be formed in multiple layers, with a middle layer serves as a moisture-storing layer. The cleaning layer is provided below this moisture-storing layer and has the necessary properties, for example, to be able to scrape off dirt or to gently clean the surface.

Oberhalb der feuchtigkeitsspeichernden Lage kann eine wasserdurchlässige Lage vorgesehen sein, die aus einem wasserdurchlässigen Material besteht. Alternativ hierzu kann die Wasserdurchlässigkeit dieser Lage auch dadurch erzielt werden, dass sich diese obere Lage nur über den Randbereich des Wischtuches erstreckt, der mittlere Bereich also frei bleibt. Dies ist dann der Bereich, durch den der Befeuchtungsverteiler die Feuchtigkeit in das Wischtuch abgeben kann, so dass sich insbesondere bei einer saugfähigen, feuchtigkeitsspeichern Schicht dann in dieser Schicht verteilt, wobei die Flüssigkeitsverteiler natürlich auch durch den Arbeitsdruck und die Bewegung der Trägerplatte längs der zu reinigenden Fläche erfolgt.Above the moisture-storing layer, a water-permeable layer may be provided which consists of a water-permeable material. Alternatively, the water permeability of this layer can also be achieved by extending this upper layer only over the edge region of the wipe, the middle area remains free. This is then the area through which the moistening distributor can deliver the moisture into the wipe, so that in particular in an absorbent, moisture-storing layer then distributed in this layer, the liquid distributor of course also by the working pressure and the movement of the support plate along cleansing surface takes place.

Im Randbereich kann dann bei dieser Ausgestaltung der klettfähige Bereich vorgesehen werden, der nicht notwendigerweise flüssigkeitsdurchlässig sein muss. Dies hat den Vorteil, dass der Randbereich optimal auf die Funktion der Klettverbindung abgestimmt werden kann, ohne dass auf die Flüssigkeitsdurchlässigkeit Rücksicht genommen werden müsste. Die einzelnen Lagen des Wischtuches können miteinander vernäht oder vernadelt sein, so dass sich ein fester Verbund ergibt.In the edge region, the viable area can then be provided in this embodiment, which does not necessarily have to be liquid-permeable. This has the advantage that the edge region can be optimally adapted to the function of the Velcro connection, without having to take into account the liquid permeability. The individual layers of the wipe can be sewn or needled together, so that there is a solid bond.

Grundsätzlich ist die Erfindung aber unabhängig von den oben beschriebenen Ausführungsformen in Verbindung mit allen Arten von Reinigungsgeräten verwendbar. Die Durchfeuchtung eines Reinigungsbelags ist dabei lediglich als optionales Merkmal zu verstehen, genauso gut können zum Beispiel eine mit Borsten versehene Fläche oder auch eine Schleiffläche an der Trägerplatte vorgesehen sein.Basically, however, the invention is usable independently of the embodiments described above in connection with all types of cleaning equipment. The moistening of a cleaning pad is merely to be understood as an optional feature, just as well, for example, provided with a bristle surface or a grinding surface on the support plate may be provided.

In Figur 1 ist die Unterseite einer erfindungsgemäßen Trägerplatte 1 dargestellt. Die Trägerplatte 1 weist im mittleren Bereich zwei gegenüberliegende Befeuchtungsverteiler 2 auf, durch die jeweils Feuchtigkeit in den Arbeitsbereich des hier als Bodenwischer ausgebildeten Reinigungsgerätes transportiert werden kann. Hierzu sind an den sich leitungsartig quer durch die Trägerplatte 1 erstreckenden Befeuchtungsverteilern 2 Austrittsöffnungen 3 vorgesehen, durch die die Feuchtigkeit nach unten in Richtung einer unteren Arbeitsfläche A abgegeben werden kann.In FIG. 1 the underside of a carrier plate 1 according to the invention is shown. The support plate 1 has in the middle region two opposite moistening distributor 2, through which moisture can be transported into the working area of the cleaning device embodied here as a floor wiper. For this purpose, two outlet openings 3 are provided on the line-like across the support plate 1 extending humidification manifolds 3, through which the moisture can be discharged downwards in the direction of a lower working surface A.

Die Trägerplatte 1 ist im Wesentlichen rechteckig ausgebildet und weist zwei gegenüberliegende Längsseiten auf. Parallel zu diesen Längsseiten sind hier zwei Reihen von jeweils vier Halteelementen 6 vorgesehen, die mit zylindrischen Bereichen die Unterseite der Trägerplatte 1 durchdringen. An den unteren Bereichen der Halteelemente 6 wiederum sind Klettflächen 8 vorgesehen, die Klettelemente aufweisen, die im Ruhebereich nicht oder nur mit einem kleinen Abschnitt aus der Ebene der die Arbeitsfläche A bildenden Unterseite der Trägerplatte 1 herausragen. Diese Klettelemente können dann mit einer geeigneten Oberfläche des nur in den Figuren 2, 3 und 5 bis 9 sichtbaren Reinigungsbelages 5 verbunden werden, wenn die Halteelemente 6 durch Druck der Trägerplatte 1 in diese eingedrückt werden.The support plate 1 is formed substantially rectangular and has two opposite longitudinal sides. Parallel to these longitudinal sides, two rows of four retaining elements 6 are provided here, which penetrate the lower side of the carrier plate 1 with cylindrical areas. In turn, velcro surfaces 8 are provided at the lower regions of the holding elements 6, which have hook-and-loop elements which do not protrude in the rest region or only with a small portion out of the plane of the underside of the carrier plate 1 forming the working surface A. These Velcro elements can then be used with a suitable surface of only in the FIGS. 2, 3 and 5 to 9 visible cleaning pad 5 are connected when the holding elements 6 are pressed by pressure of the support plate 1 in this.

Dadurch, dass die Halteelemente 6 bei Druck in die Aufnahmen 7 der Trägerplatte 1 zusammen mit den Klettflächen 8 eingedrückt werden können, kann ein Verkratzen des Bodens bei Aufstellen des Reinigungsgerätes ohne Reinigungsbelag 5 in Verbindung mit den abgeflachten Kopfbereichen der Klettelemente zusätzlich vermieden werden.Characterized in that the retaining elements 6 can be pressed together with the Velcro surfaces 8 in pressure in the receptacles 7 of the support plate 1, a scratching of the soil during installation of the cleaning device without cleaning pad 5 in conjunction with the flattened head portions of the Velcro elements can be additionally avoided.

In den Figuren 2 und 3 ist die Trägerplatte 1 aus Figur 1 in einer Ansicht auf die Längsseite (Figur 2) sowie auf die Querseite (Figur 3) dargestellt. Im oberen Bereich weist die Trägerplatte 1 ein Gelenk 16 auf, über das sie mit einem Stil des Wischgerätes verbunden werden kann. Zwischen den beiden Teilen des Gelenks 16 ist ein Verteilanschluss 4 vorgesehen, der einerseits mit den beiden Befeuchtungsverteiler 2 und andererseits (hier nicht sichtbar) mit einer druckbetätigten Zufuhr für Flüssigkeit des Reinigungsgerätes in Strömungsverbindung steht. In den Figuren 2 und 3 ist zu erkennen, dass der Reinigungsbelag 5 an der Unterseite der Halteelemente 6 gehalten ist.In the FIGS. 2 and 3 is the support plate 1 off FIG. 1 in a view on the long side ( FIG. 2 ) as well as on the transverse side ( FIG. 3 ). In the upper area, the support plate 1 has a hinge 16, via which it can be connected to a style of the wiper device. Between the two parts of the joint 16, a distribution port 4 is provided, on the one hand with the two humidification distributor 2 and on the other hand (not visible here) with a pressure-actuated supply for liquid the cleaning device is in flow communication. In the FIGS. 2 and 3 it can be seen that the cleaning pad 5 is held on the underside of the holding elements 6.

Der in Figur 4 gezeigte Schnitt gemäß der Schnittlinie A-A aus Figur 3 verdeutlicht die Funktion der Halteelemente 6. Die Halteelemente 6 sind hier stopfenartig ausgebildet und in Querführungen 9 in Aufnahmen 7 einer im oberen Bereich relativ zur Srbeitsfläche (A) an der Trägerplatte 1 beweglich gelagerten Trägerelement 11 geführt. Die Querführungen 9 sind hier nach der Art eines Gewindeganges ausgebildet, könnten alternativ aber besipielsweise auf von schiefen Ebenen gebildet sein. Die Halteelemente 6 sind mit Randbereichen in den Gängen dieses Gewindes geführt, so dass ein Hineindrücken der Halteelemente 6 in die Trägerplatte 1 nicht nur deren Verlagerung nach oben, sondern auch ein Verdrehen der Halteelemente 6 mit den darauf angeordneten Klettflächen 8 um eine Schraubachse S bewirkt.The in FIG. 4 shown section according to the section line AA FIG. 3 illustrates the function of the holding elements 6. The holding elements 6 are formed here like a plug and guided in transverse guides 9 in receptacles 7 in the upper region relative to the working surface (A) on the support plate 1 movably mounted support member 11. The transverse guides 9 are formed here in the manner of a thread turn, but could alternatively be formed on inclined planes. The holding elements 6 are guided with edge regions in the corridors of this thread, so that pushing the holding elements 6 into the carrier plate 1 not only their displacement upwards, but also causes a rotation of the holding elements 6 with the velcro surfaces 8 arranged thereon about a screw axis S.

Figur 5 zeigt dies als Einzelheit Z in vergrößerter Darstellung. Im oberen Bereich weisen die Halteelemente 6 einen Widerlagerbereich 15 auf, der die Beweglichkeit nach unten begrenzt. Gleichzeitig ist die Beweglichkeit nach oben durch obere Anschläge eingeschränkt. Zur Aufnahme der Halteelemente 6 weist das Trägerelement 11 die Aufnahmen 7 auf, die sich durch die Trägerplatte 1 hindurch erstrecken, so dass die Halteelemente 6 in eine Richtung senkrecht zur zu reinigenden Fläche beweglich geführt sind. FIG. 5 shows this as a detail Z in an enlarged view. In the upper region, the holding elements 6 on an abutment portion 15, which limits the mobility down. At the same time, the mobility upwards is limited by upper stops. For receiving the holding elements 6, the carrier element 11 on the receptacles 7, which extend through the support plate 1 through, so that the holding elements 6 are guided in a direction perpendicular to the surface to be cleaned.

In den Figuren 6 bis 9 sind mögliche Reinigungsbeläge 5 dargestellt, die in Verbindung mit dem hier gezeigten Reinigungsgerät verwendet werden können. Figur 6 zeigt den Schichtaufbau eines mehrlagigen Wischtuches. Dieses als Reinigungsbelag 5 verwendete Wischtuch weist eine untere Reinigungslage 14 auf, auf der eine feuchtigkeitsspeichernde Lage 13 vorgesehen ist. Diese feuchtigkeitsspeichernde Lage 13 kann beispielsweise aus Schaumstoff oder einem anderen, Feuchtigkeit zwischenspeicherndem Material bestehen. Letztlich hängt dies vom Anwendungszweck und vom gewünschten Durchfeuchtungsgrad ab.In the FIGS. 6 to 9 possible cleaning pads 5 are shown, which can be used in conjunction with the cleaning device shown here. FIG. 6 shows the layer structure of a multi-layer wipe. This wipe used as a cleaning pad 5 has a lower cleaning layer 14, on which a moisture-storing layer 13 is provided. This moisture-storing layer 13 may be made, for example, of foam or other moisture buffering material. Ultimately, this depends on the application and the desired degree of moisture penetration.

Figur 7 zeigt die Ausgestaltung des Wischtuches nach Figur 6 als Einzelheit X in vergrößerter Darstellung. Zu erkennen ist hier, dass oberhalb der feuchtigkeitsspeichernden Lage 13 eine weitere, wasserdurchlässige Lage 12 vorgesehen ist. Diese hat zum einen die Funktion, dass die Feuchtigkeit, die aus den Befeuchtungsverteilern 2 ausgegeben wird, in die darunter befindliche feuchtigkeitsspeichernde Lage 13 eindiffundieren kann. Zum anderen stellt diese wasserdurchlässige Lage 12 die belagseitige Klettfähigkeit bereit. FIG. 7 shows the design of the wipe after FIG. 6 as a detail X in an enlarged view. It can be seen here that above the moisture-storing layer 13, a further, water-permeable layer 12 is provided. These on the one hand has the function that the moisture that is emitted from the moistening distributors 2 can diffuse into the moisture-storing layer 13 located underneath. On the other hand, this water-permeable layer 12 provides the coating-side Velcro capability.

In den Figuren 8 und 9 sind weitere Ausgestaltungen eines möglichen Reinigungsbelags 5 gezeigt. Die Variante nach Figur 8 weist eine andere Ausgestaltung der wasserdurchlässigen Lage 12 auf. Hier ist erstreckt sich die wasserdurchlässige Lage 12 nur auf den äußeren Bereich des Reinigungsbelags 5, während der mittlere Bereich freigelassen ist, so dass die Befeuchtungsverteiler 2 die Feuchtigkeit unmittelbar in die feuchtigkeitsspeichernde Lage 13 einbringen können. Natürlich können Zwischenschichten vorgesehen sein, die unterschiedlichen Zwecken dienen können.In the FIGS. 8 and 9 Further embodiments of a possible cleaning pad 5 are shown. The variant after FIG. 8 has another embodiment of the water-permeable layer 12. Here, the water-permeable layer 12 extends only to the outer region of the cleaning pad 5, while the middle region is left open, so that the moistening distributor 2 can introduce the moisture directly into the moisture-storing layer 13. Of course, intermediate layers can be provided which can serve different purposes.

Die Ausgestaltung nach Figur 8 ermöglicht es, dass die klettfähigen Bereiche hinreichend fest ausgebildet werden können, so dass auf eine mögliche Eignung zum Flüssigkeitsdurchlass keine Rücksicht genommen werden muss. Gleichzeitig kann hier der mehrlagige Verbund des Reinigungsbelags 5 über eine Naht 10 miteinander vernäht werden. Auf diese Weise kann ein stabiler Verbund geschaffen werden, der einerseits eine feste Naht 10, feste Verbindungsstellen für die Klettbereiche und anderseits aber auch eine gute Flüssigkeitsdurchlässigkeit im mittleren Bereich bereitstellt.The design after FIG. 8 makes it possible that the velcro-capable areas can be formed sufficiently strong, so that no consideration must be given to a possible suitability for fluid passage. At the same time, the multilayer composite of the cleaning pad 5 can be sewn together via a seam 10 here. In this way, a stable bond can be created, on the one hand provides a solid seam 10, fixed joints for the Velcro areas and on the other hand, but also a good fluid permeability in the middle region.

In Figur 9 ist eine weitere Ausgestaltung als Abwandlung der in Figur 8 dargestellten Variante dargestellt. Bei dieser Variante ist unterhalb der feuchtigkeitsspeichernden Lage 13 eine weitere Lage vorgesehen, die zwischen der feuchtigkeitsspeichernden Lage 13 und der Reinigungslage 14 angeordnet ist. Diese zusätzliche Lage ragt seitlich über den Reinigungsbelag 5 heraus und ist nach oben zweifach umgeschlagen, wobei der umgeschlagene Bereich dann die wasserdurchlässige Schicht 12 bildet. Diese liegt auf der Oberseite der feuchtigkeitsspeichernden Schicht 13 auf und kann über die Naht 10 zusammen mit den übrigen Lagen fixiert sein.In FIG. 9 is a further embodiment as a modification of in FIG. 8 shown variant shown. In this variant, a further layer is provided below the moisture-storing layer 13, which is arranged between the moisture-storing layer 13 and the cleaning layer 14. This additional layer protrudes laterally beyond the cleaning pad 5 and is turned up twice, wherein the turned-over area then forms the water-permeable layer 12. This lies on top of the moisture-storing layer 13 and can be fixed via the seam 10 together with the other layers.

In den Figuren wurde die Erfindung anhand eines als Bodenwischer ausgebildeten Reinigungsgerätes beispielhaft beschrieben. Diese Beschreibung dient ausschließlich der Verdeutlichung der erfindungsgemäßen Vorteile, ohne die Anwendung der Erfindung auf den Bodenwischer oder ein Feuchtwischtuch einzuschränken.In the figures, the invention has been described by way of example with reference to a trained as a floor wiper cleaning device. This description is for exclusive use the clarification of the advantages of the invention, without restricting the application of the invention to the floor wiper or a wet wipe.
