Die Erfindung betrifft ein Reinigungsgerät, insbesondere ein Bodenreinigungsgerät, mit einer rotierbar gelagerten Reinigungswalze zur Reinigung einer Fläche, welcher Reinigungswalze ein Walzenmitnehmer zur Drehzusammenwirkung mit einer geräteseitig angetriebenen Welle zugeordnet ist, welcher Walzenmitnehmer zumindest teilweise in eine axiale Walzenaussparung der Reinigungswalze einführbar ist, und wobei an dem Walzenmitnehmer und der Walzenaussparung in Zusammenwirkung bringbare Kupplungsmittel ausgebildet sind.The invention relates to a cleaning device, in particular a floor cleaning device, with a rotatably mounted cleaning roller for cleaning a surface, which cleaning roller is assigned a Walzenmitnehmer for rotational cooperation with a device side driven shaft, which Walzenmitnehmer is at least partially inserted into an axial roller recess of the cleaning roller, and wherein the Walzenmitnehmer and the roller recess can be brought into cooperation engageable coupling means.

Stand der TechnikState of the art

Reinigungsgeräte der vorgenannten Art sind bekannt. Diese verfügen über eine oder mehrere Reinigungswalzen, welche üblicherweise mit Flüssigkeit beaufschlagbar sind und zum Feuchtwischen einer zu reinigenden Fläche dienen. Die Reinigungswalze ist rotierbar innerhalb des Reinigungsgerätes gelagert.Cleaning devices of the aforementioned type are known. These have one or more cleaning rollers, which are usually acted upon with liquid and are used for damp mopping a surface to be cleaned. The cleaning roller is rotatably mounted within the cleaning device.

Die Druckschrift WO 1997/045052 A1 offenbart beispielsweise ein Reinigungsgerät mit einem röhrenartigen Bürstenkörper, in welchen eine Welle des Reinigungsgerätes einsteckbar ist. Die drehfeste Kupplung des Bürstenkörpers auf der Welle erfolgt über einen auf der Welle drehfest gehalterten Mitnehmer, welcher mit radial nach innen vorspringenden Mitnahmevorsprüngen des Bürstenkörpers zusammenwirkt.The publication WO 1997/045052 A1 discloses, for example, a cleaning device with a tubular brush body, in which a shaft of the cleaning device can be inserted. The non-rotatable coupling of the brush body on the shaft via a rotationally fixed content Erten on the shaft driver, which cooperates with radially inwardly projecting driving projections of the brush body.

Die korrespondierenden Vorsprünge sind für eine Drehmomentübertragung so ausgestaltet, dass diese in Umfangsrichtung möglichst spielfrei aneinander liegen. Dadurch ergibt sich ein relativ hoher Herstellungsaufwand sowie die Gefahr eines Verkantens der Vorsprünge beim Verbinden der Reinigungswalze mit der Welle.The corresponding projections are designed for torque transmission so that they lie as free of play as possible in the circumferential direction. This results in a relatively high production cost and the risk of tilting of the projections when connecting the cleaning roller to the shaft.

Aus der DE 198 20 628 C1 ist ein Reinigungsgerät bekannt, bei welchem eine an der Reinigungswalze vorgesehene Feder, die aus einem Zahnrad und Nuten an der Innenwand des Aufnahmeraumes bestehenden Kupplungsmittel des Walzenmitnehmers und der Reinigungsbürste in deren Verschieberichtung zueinander beaufschlagt.From the DE 198 20 628 C1 a cleaning device is known in which a provided on the cleaning roller spring which acts on the inner wall of the receiving space consisting of a gear and grooves coupling means of Walzenmitnehmers and the cleaning brush in the direction of displacement to each other.

Zusammenfassung der ErfindungSummary of the invention

Es ist daher Aufgabe der Erfindung, ein Reinigungsgerät anzugeben mit einer vorteilhaften Sicherung der Kupplungsmittel, der Reinigungswalze und des Walzenmitnehmers zueinander.It is therefore an object of the invention to provide a cleaning device with an advantageous securing the coupling means, the cleaning roller and the Walzenmitnehmers each other.

Diese Aufgabe ist beim Gegenstand des Anspruches 1 gelöst, wobei darauf abgestellt ist, dass der Walzenmitnehmer eine Walzenmitnehmerfeder aufweist, durch welche die Kupplungsmittel in einem Montagezustand zur Übertragung eines Drehmomentes gegeneinander sicherbar sind, derart, dass eine Rückstellkraft der Walzenmitnehmerfeder das Kupplungsmittel des Walzenmitnehmers in axialer Richtung der Reinigungswalze gegen das Kupplungsmittel der Reinigungswalze drückt oder umgekehrt.This object is achieved in the subject matter of claim 1, being based on the fact that the Walzenmitnehmer has a Walzenmitnehmerfeder by which the coupling means in an assembled state for transmitting torque against each other are securable, such that a restoring force of Walzenmitnehmerfeder the coupling means of Walzenmitnehmers in the axial Direction of the cleaning roller against the coupling agent of the cleaning roller pushes or vice versa.

Zur Lösung schlägt die Erfindung vor, dass der Walzenmitnehmer eine Walzenmitnehmerfeder aufweist, durch welche die Kupplungsmittel in einem Montagezustand zur Übertragung eines Drehmomentes gegeneinander sicherbar sind.To solve the invention proposes that the Walzenmitnehmer has a Walzenmitnehmerfeder through which the coupling agent in a Mounting state for the transmission of torque against each other are secured.

Gemäß der Erfindung erfolgt die drehmomentübertragende Kopplung zwischen dem Walzenmitnehmer und der Reinigungswalze nun nicht mehr (zumindest nicht ausschließlich) über einen Eingriff der Kupplungsmittel in Umfangsrichtung. Vielmehr ist dem Walzenmitnehmer eine Walzenmitnehmerfeder zugeordnet, deren Rückstellkraft das Kupplungsmittel des Walzenmitnehmers in axialer Richtung der Reinigungswalze gegen das Kupplungsmittel der Reinigungswalze drückt, oder umgekehrt. Dadurch erfolgt die Drehmomentübertragung im Wesentlichen durch die Walzenmitnehmerfeder. Die miteinander verbundenen Kupplungsmittel dienen als Anschlagflächen, gegen welche die Rückstellkraft der Walzenmitnehmerfeder wirkt.According to the invention, the torque-transmitting coupling between the Walzenmitnehmer and the cleaning roller is no longer (at least not exclusively) via an engagement of the coupling means in the circumferential direction. Rather, the Walzenmitnehmer a Walzenmitnehmerfeder is assigned, the restoring force presses the coupling means of the Walzenmitnehmers in the axial direction of the cleaning roller against the coupling agent of the cleaning roller, or vice versa. As a result, the torque transmission takes place essentially by the Walzenmitnehmerfeder. The interconnected coupling means serve as abutment surfaces against which the restoring force of the Walzenmitnehmerfeder acts.

Es wird vorgeschlagen, dass die Walzenmitnehmerfeder eine koaxial an dem Walzenmitnehmer angeordnete Schraubenfeder ist. Gemäß dieser Ausgestaltung ist die Walzenmitnehmerfeder über den Walzenmitnehmer geschoben, so dass die Windungen der Walzenmitnehmerfeder von außen an der Umfangsfläche des Walzenmitnehmers anliegen. Sofern der Innendurchmesser der Walzenmitnehmerfeder dem Außendurchmesser des Walzenmitnehmers entspricht, ergibt sich automatisch eine Zentrierung der Walzenmitnehmerfeder an dem Walzenmitnehmer und innerhalb der Walzenaussparung der Reinigungswalze, so dass die Rückstellkraft der Walzenmitnehmerfeder in Umfangsrichtung des Walzenmitnehmers im Wesentlichen gleich verteilt ist und somit - je nach der geometrischen Form der Kupplungsmittel - in Umfangsrichtung gleichmäßig gegen die Kupplungsmittel wirken kann. Somit kann das Drehmoment gegebenenfalls über den gesamten Umfang des Walzenmitnehmers auf die Reinigungswalze übertragen werden. Dies ist insbesondere dann gegeben, wenn sowohl das Kupplungsmittel des Walzenmitnehmers als auch das Kupplungsmittel der Reinigungswalze bezogen auf einen radialen Querschnitt ringförmig ausgebildet sind.It is proposed that the Walzenmitnehmerfeder is coaxially arranged on the Walzenmitnehmer coil spring. According to this embodiment, the Walzenmitnehmerfeder is pushed over the Walzenmitnehmer, so that the turns of the Walzenmitnehmerfeder rest against the outer surface of the Walzenmitnehmers. If the inner diameter of the Walzenmitnehmerfeder corresponds to the outer diameter of the Walzenmitnehmers, automatically results in a centering of Walzenmitnehmerfeder on the Walzenmitnehmer and within the roller recess of the cleaning roller, so that the restoring force of Walzenmitnehmerfeder is distributed in the circumferential direction of the Walzenmitnehmers substantially equal and thus - depending on the geometric shape of the coupling agent - can act evenly against the coupling agent in the circumferential direction. Thus, the torque can optionally be transmitted over the entire circumference of the Walzenmitnehmers on the cleaning roller. This is particularly true when both the coupling means of Walzenmitnehmers and the coupling means of the cleaning roller are annular with respect to a radial cross-section.

Es wird vorgeschlagen, dass die Walzenmitnehmerfeder in dem Montagezustand der Kupplungsmittel so an einem Kupplungsmittel der Reinigungswalze angreift, dass die Rückstellkraft der Walzenmitnehmerfeder den Walzenmitnehmer aus der Walzenaussparung herauszudrücken sucht. Die Walzenmitnehmerfeder wirkt somit gegen das Kupplungsmittel der Reinigungswalze. Dadurch drückt die Walzenmitnehmerfeder einerseits die Kupplungsmittel der Reinigungswalze und des Walzenmitnehmers gegeneinander und zum andern den Walzenmitnehmer gegen eine Kupplungseinrichtung des Reinigungsgerätes, welche den Walzenmitnehmer mit einer Antriebswelle eines Elektromotors des Reinigungsgerätes verbindet. Hierdurch ergeben sich bei der Montage bzw. Demontage der Reinigungswalze Vorteile, da der Nutzer die Länge der Reinigungswalze mit zumindest teilweise darin eingeführtem Walzenmitnehmer durch Spannen bzw. Entspannen der Walzenmitnehmerfeder, d.h. durch eine axiale Bewegung des Walzenmitnehmers relativ zu der Reinigungswalze, variieren kann. Durch den bei Kompression der Walzenmitnehmerfeder geschaffenen Abstand zwischen der Reinigungswalze und der Kupplungseinrichtung und/oder einem weiteren Lager für den gegenüberliegenden Endbereich der Reinigungswalze ist es möglich, die Reinigungswalze plus den Walzenmitnehmer aus dem Reinigungsgerät zu entfernen. In dem Montagezustand der Kupplungsmittel wirkt die Walzenmitnehmerfeder aufgrund ihrer Rückstellkraft gegen zumindest eines der Kupplungsmittel, so dass die Drehmomentübertragung von der Welle auf die Reinigungswalze möglich ist.It is proposed that the Walzenmitnehmerfeder engages in the assembled state of the coupling means to a coupling means of the cleaning roller, that the restoring force of the Walzenmitnehmerfeder seeks to push out the Walzenmitnehmer from the roll recess. The Walzenmitnehmerfeder thus acts against the coupling agent of the cleaning roller. As a result, the Walzenmitnehmerfeder presses on the one hand the coupling means of the cleaning roller and the Walzenmitnehmers against each other and the other Walzenmittnehmer against a coupling device of the cleaning device, which connects the Walzenmitnehmer with a drive shaft of an electric motor of the cleaning device. This results in the assembly or disassembly of the cleaning roller advantages, since the user can vary the length of the cleaning roller with at least partially inserted therein Walzenmitnehmer by tensioning or relaxing the Walzenmitnehmerfeder, ie by an axial movement of the Walzenmitnehmers relative to the cleaning roller. By created in compression of the Walzenmitnehmerfeder distance between the cleaning roller and the coupling device and / or another bearing for the opposite End region of the cleaning roller, it is possible to remove the cleaning roller plus the Walzenmitnehmer from the cleaning device. In the assembled state of the coupling means, the Walzenmitnehmerfeder acts due to their restoring force against at least one of the coupling means, so that the torque transmission from the shaft to the cleaning roller is possible.

Des Weiteren ist vorgesehen, dass ein Kupplungsmittel der Reinigungswalze in dem Montagezustand bezogen auf eine axiale Richtung der Reinigungswalze zwischen einem Kupplungsmittel des Walzenmitnehmers und der Walzenmitnehmerfeder angeordnet ist. In dem Montagezustand der Kupplungsmittel wirkt die Walzenmitnehmerfeder von der dem Kupplungsmittel des Walzenmitnehmers abgewandten Seite gegen das Kupplungsmittel der Reinigungswalze, so dass die gespannte Walzenmitnehmerfeder einerseits zur Drehmomentübertragung gegen die korrespondierenden Kupplungsmittel wirkt, und zum anderen den Walzenmitnehmer gegen eine Kupplungseinrichtung der geräteseitig angetriebenen Welle presst und somit die Rotation der Reinigungswalze ermöglicht. Diese Ausbildung ermöglicht gleichzeitig eine besonders komfortable Montage und Demontage der Reinigungswalze innerhalb des Reinigungsgerätes. Zur Montage der Reinigungswalze wird der Walzenmitnehmer in die Walzenaussparung eingeschoben bis das Kupplungsmittel des Walzenmitnehmers in axialer Richtung der Reinigungswalze hinter das Kupplungsmittel der Reinigungswalze greift. Dabei wird die Walzenmitnehmerfeder gespannt, so dass sich die axiale Gesamtlänge der Reinigungswalze inklusive Walzenmitnehmer reduziert und eine komfortable Montage zur drehmoment-übertragenden Kopplung der Reinigungswalze mit der Welle möglich ist. Zur Entnahme der Reinigungswalze aus dem Reinigungsgerät ergreift der Nutzer die Reinigungswalze und verlagert diese entgegen der Rückstellkraft der Walzenmitnehmerfeder. Dadurch schiebt sich der Walzenmitnehmer weiter in die Reinigungswalze hinein, bis das Kupplungsmittel des Walzenmitnehmers um einen gewissen Betrag von dem Kupplungsmittel der Reinigungswalze beabstandet ist. In dieser Position ist die Gesamtlänge von Reinigungswalze und Walzenmitnehmer so verringert, dass die Reinigungswalze aus dem Reinigungsgerät entnommen werden kann.Furthermore, it is provided that a coupling means of the cleaning roller is arranged in the assembled state relative to an axial direction of the cleaning roller between a coupling means of the Walzenmitnehmers and the Walzenmitnehmerfeder. In the assembled state of the coupling means, the Walzenmitnehmerfeder acts from the coupling means of Walzenmitnehmers opposite side against the coupling agent of the cleaning roller, so that the tensioned Walzenmitnehmerfeder acts on the one hand to transmit torque against the corresponding coupling means, and on the other presses the Walzenmitnehmer against a coupling device of the device side driven shaft and thus allowing the rotation of the cleaning roller. This training also allows a particularly convenient assembly and disassembly of the cleaning roller inside the cleaning device. For mounting the cleaning roller, the roller driver is inserted into the roller recess until the coupling means of the roller carrier engages behind the coupling means of the cleaning roller in the axial direction of the cleaning roller. The Walzenmitnehmerfeder is tensioned so that the axial total length of the cleaning roller including Walzenmitnehmer reduced and a comfortable assembly for torque-transmitting coupling of the cleaning roller with the shaft is possible. To remove the cleaning roller from the cleaning device, the user grasps the cleaning roller and displaces it against the restoring force of the roller driving spring. As a result, the Walzenmitnehmer pushes further into the cleaning roller until the coupling means of the Walzenmitnehmers by a certain amount of the coupling means of Cleaning roller is spaced. In this position, the total length of cleaning roller and Walzenmitnehmer is reduced so that the cleaning roller can be removed from the cleaning device.

Es wird vorgeschlagen, dass die Kupplungsmittel nach der Art einer Rastverbindung in Zusammenwirkung bringbar sind. Dies ermöglicht die zuvor beschriebene, insbesondere verliersichere, Kopplung der Kupplungsmittel.It is proposed that the coupling agents can be brought together in the manner of a latching connection. This allows the previously described, in particular captive, coupling of the coupling agent.

Es wird vorgeschlagen, dass das Kupplungsmittel der Reinigungswalze ringförmig ausgebildet ist. Zum Herstellen einer Eingriffsstellung zwischen dem Kupplungsmittel der Reinigungswalze und dem Kupplungsmittel des Walzenmitnehmers gleitet das Kupplungsmittel des Walzenmitnehmers über das Kupplungsmittel der Reinigungswalze bis das Kupplungsmittel des Walzenmitnehmers hinter das Kupplungsmittel der Reinigungswalze schnappt. Vorteilhaft weist das Kupplungsmittel des Walzenmitnehmers dazu elastische Materialeigenschaften und die Form eines Hakens auf.It is proposed that the coupling agent of the cleaning roller is annular. In order to establish an engagement position between the coupling means of the cleaning roller and the coupling means of the roller follower, the coupling means of the roller follower slides over the coupling means of the cleaning roller until the coupling means of the roller follower snaps behind the coupling means of the cleaning roller. Advantageously, the coupling means of Walzenmitnehmers this elastic material properties and the shape of a hook.

Schließlich wird vorgeschlagen, dass eine Kupplungseinrichtung der geräteseitig angetriebenen Welle und der Walzenmitnehmer korrespondierende Kupplungselemente zur drehmomentübertragenden Verbindung aufweisen, wobei ein Kupplungselement des Walzenmitnehmers an dem von einem Kupplungsmittel des Walzenmitnehmers abgewandten Endbereich des Walzenmitnehmers ausgebildet ist. Der Walzenmitnehmer ist somit von der Kupplungseinrichtung bzw. der geräteseitig angetriebenen Welle trennbar ausgebildet, so dass eine besonders einfache Entnahme des Walzenmitnehmers bzw. der Reinigungswalze aus dem Reinigungsgerät möglich ist. Zur Entnahme wird der Walzenmitnehmer axial in die Reinigungswalze hineinverlagert, so dass neben der Reinigungswalze ein Freiraum entsteht, der eine bequeme Entnahme der Reinigungswalze inklusive Walzenmitnehmer ermöglicht. Die korrespondierenden Kupplungselemente können nach der Art von in axialer Richtung des Walzenmitnehmers vorstehenden Vorsprüngen ausgebildet sein, welche formkorrespondierend ineinandergreifen können und somit die Drehmomentübertragung bewirken.Finally, it is proposed that a coupling device of the device-side driven shaft and the roller cam have corresponding coupling elements for the torque-transmitting connection, wherein a coupling element of the roller cam is formed on the end region of the roller cam facing away from a coupling means of the roller cam. The Walzenmitnehmer is thus separable from the coupling device or the device-side driven shaft, so that a particularly simple removal of the Walzenmitnehmers or the cleaning roller from the cleaning device is possible. To remove the Walzenmitnehmer is axially displaced into the cleaning roller, so that in addition to the cleaning roller creates a free space, which allows a convenient removal of the cleaning roller including Walzenmitnehmer. The corresponding ones Coupling elements may be formed according to the type of projections projecting in the axial direction of the roller driver, which projections can mesh with one another in a corresponding shape and thus effect the transmission of torque.

Beschreibung der AusführungsformenDescription of the embodiments

Dargestellt und beschrieben ist zunächst mit Bezug zu Figur 1 ein Reinigungsgerät 1 in Form eines Feuchtreinigungsgerätes zur Feuchtreinigung einer zu reinigenden Fläche. Das Reinigungsgerät 1 weist ein Vorsatzgerät 13 auf, welches bei einem Reinigungsvorgang in Kontakt mit der zu reinigenden Fläche steht. Das Vorsatzgerät 13 weist hierbei beispielsweise zwei Reinigungswalzen 2 auf, welche mit Flüssigkeit, beispielsweise Wasser, beaufschlagt werden können. Hierzu können die Reinigungswalzen 2 beispielsweise mit der Flüssigkeit besprüht werden oder mit einem feuchten Walzenbelag 15 ummantelt werden. Das Reinigungsgerät 1 stützt sich über die beiden Reinigungswalzen 2 auf der zu reinigenden Fläche ab. Die Reinigungswalzen 2 erstrecken sich quer zu einer üblichen Verfahrrichtung r des Reinigungsgerätes 1, welche aus einer üblichen Arbeitsbewegung eines Nutzers des Reinigungsgerätes 1 resultiert, nämlich generell abwechselnd vor und zurück, dies gegebenenfalls weiter unter Ausweichen in eine nächstliegende, parallele Reinigungsbahn. Die Reinigungswalzen 2 erstrecken sich hier annähernd über die gesamte quer zur Verfahrrichtung r stehende Breite des Reinigungsgerätes 1. Entsprechend der gezeigten Anordnung ist jeweils eine Reinigungswalze 2 bei einer Bewegung des Reinigungsgerätes 1 in Verfahrrichtung r vorne bzw. hinten an dem Vorsatzgerät 13 angeordnet. Die Reinigungswalzen 2 sind über einen Elektromotor antreibbar, d. h. um eine Drehachse rotierbar. Während eines üblichen Verfahrvorgangs des Reinigungsgerätes 1, ohne Bearbeitung einer zu reinigenden Fläche, sind die Reinigungswalzen 2 vorteilhaft nicht aktiv angetrieben. Vielmehr ergibt sich dann allein aufgrund des Reibschlusses zu der zu reinigenden Fläche eine passive Rotation der Reinigungswalzen 2. Während eines Reinigungsvorgangs der Fläche mittels der Reinigungswalzen 2 werden diese hingegen aktiv mittels des Elektromotors rotiert. Dabei stellt sich eine Wischkante entlang der Berührungslinie zwischen der Reinigungswalze 2 und der zu reinigenden Fläche ein. Diese Wischkante ermöglicht die Reinigung der Fläche durch Bewegung relativ zu der Fläche, wodurch Schmutz gelöst wird.Shown and described is first with reference to FIG. 1 a cleaning device 1 in the form of a wet cleaning device for the wet cleaning of a surface to be cleaned. The cleaning device 1 has an attachment 13, which is in a cleaning operation in contact with the surface to be cleaned. The attachment 13 in this case has, for example, two cleaning rollers 2, which can be acted upon with liquid, such as water. For this purpose, the cleaning rollers 2 can be sprayed, for example, with the liquid or coated with a moist roll coating 15. The cleaning device 1 is supported by the two cleaning rollers 2 on the surface to be cleaned. The cleaning rollers 2 extend transversely to a usual direction of travel r of the cleaning device 1, which results from a normal working movement of a user of the cleaning device 1, namely generally alternately back and forth, this possibly further while evading into a nearest, parallel cleaning track. The cleaning rollers 2 extend here approximately over the entire transverse to the direction of travel r width of the cleaning device 1. According to the arrangement shown, a cleaning roller 2 at a movement of the cleaning device 1 in the direction of travel r front or rear of the attachment 13 is arranged. The cleaning rollers 2 are driven by an electric motor, that is rotatable about a rotation axis. During a conventional movement of the cleaning device 1, without processing a surface to be cleaned, the cleaning rollers 2 are advantageously not actively driven. On the contrary, a passive rotation of the cleaning rollers 2 then results solely from the frictional engagement with the surface to be cleaned. During a cleaning process of the surface by means of the cleaning rollers 2, however, they are actively rotated by means of the electric motor. In this case, a wiping edge is established along the contact line between the cleaning roller 2 and the surface to be cleaned. This wiper edge makes it possible to clean the surface by moving it relative to the surface, which dissolves dirt.

Figur 2 zeigt eine Reinigungswalze 2, welche mit einem Walzenmitnehmer 3 verbunden ist, der zur Übertragung eines Drehmomentes von einer Welle (nicht dargestellt) des Elektromotors auf die Reinigungswalze 2 dient. Hierzu ist der Walzenmitnehmer 3 mit einer Kupplungseinrichtung 4 verbunden, welche wiederum über einen Zahnriemen 14 mit der Welle des Elektromotors gekoppelt ist. Auf der der Kupplungseinrichtung 4 entgegen gesetzten Seite der Reinigungswalze 2 ist ein Lager 5 angeordnet, welches zusammen mit der Kupplungseinrichtung 4 zur Halterung der Reinigungswalze 2 in dem Reinigungsgerät 1 dient. Der Walzenmitnehmer 3 ist in die Reinigungswalze 2 eingeführt. FIG. 2 shows a cleaning roller 2, which is connected to a Walzenmitnehmer 3, which serves for transmitting a torque from a shaft (not shown) of the electric motor to the cleaning roller 2. For this purpose, the Walzenmitnehmer 3 is connected to a coupling device 4, which in turn via a toothed belt 14 with the shaft of the electric motor is coupled. On the coupling device 4 opposite side of the cleaning roller 2, a bearing 5 is arranged, which serves together with the coupling device 4 for holding the cleaning roller 2 in the cleaning device 1. The Walzenmitnehmer 3 is inserted into the cleaning roller 2.

Figur 3 zeigt die Reinigungswalze 2, den Walzenmitnehmer 3, die Kupplungseinrichtung 4 und das Lager 5 in einem Längsschnitt. Der Walzenmitnehmer 3 weist an seinem freien Endbereich eine Kulisse aus mehreren Kupplungsmitteln 8 auf, welche in Umfangsrichtung des Walzenmitnehmers 3 nebeneinander angeordnet und durch Freiräume 10 voneinander beabstandet sind. Die Kupplungsmittel 8 sind hakenförmig ausgebildet und weisen radial nach außen, d. h. in Richtung der den Walzenmitnehmer 3 koaxial umgebenden Reinigungswalze 2. Die Reinigungswalze 2 weist eine den Walzenmitnehmer 3 aufnehmende Walzenaussparung 6 auf, welche zumindest teilweise in axialer Richtung innerhalb der Reinigungswalze 2 ausgebildet ist. Die Walzenaussparung 6 weist ein ringförmiges, nach radial innen, d. h. in Richtung des Walzenmitnehmers 3, weisendes Kupplungsmittel 7 auf. In der dargestellten Eingriffsstellung greifen die Kupplungsmittel 8 des Walzenmitnehmers 3 hinter das Kupplungsmittel 7 der Reinigungswalze 2, so dass der Walzenmitnehmer 3 verliersicher mit der Reinigungswalze 2 verbunden ist. FIG. 3 shows the cleaning roller 2, the Walzenmitnehmer 3, the coupling device 4 and the bearing 5 in a longitudinal section. The Walzenmitnehmer 3 has at its free end to a backdrop of a plurality of coupling means 8, which are arranged in the circumferential direction of the Walzenmitnehmers 3 side by side and spaced by free spaces 10 from each other. The coupling means 8 are hook-shaped and have radially outwards, ie in the direction of the Walzenmitnehmer 3 coaxially surrounding cleaning roller 2. The cleaning roller 2 has a Walzenmitnehmer 3 receiving roller recess 6, which is at least partially formed in the axial direction within the cleaning roller 2. The roller recess 6 has an annular, radially inward, ie in the direction of Walzenmitnehmers 3, facing coupling means 7. In the illustrated engagement position, the coupling means 8 of the Walzenmitnehmers 3 engage behind the coupling means 7 of the cleaning roller 2, so that the Walzenmitnehmer 3 is captively connected to the cleaning roller 2.

Der Walzenmitnehmer 3 trägt auf seiner Umfangsfläche eine Walzenmitnehmerfeder 9, welche hier als Schraubenfeder ausgebildet ist. Die Walzenmitnehmerfeder 9 liegt formkorrespondierend an dem Walzenmitnehmer 3 an, so dass eine koaxiale Zentrierung gegeben ist. An der den Kupplungsmitteln 8 entgegengesetzten Seite weist der Walzenmitnehmer 3 Kupplungselemente 12 auf, welche sich in Eingriff mit Kupplungselementen 11 der Kupplungseinrichtung 4 befinden. Die Kupplungselemente 11, 12 sind als formkorrespondierende Vorsprünge ausgebildet, so dass ein Drehmoment von der Kupplungseinrichtung 4 auf den Walzenmitnehmer 3 übertragen werden kann. Die Kupplungseinrichtung 4 ist mittels des Zahnriemens 14 mit dem Elektromotor des Reinigungsgerätes 1 verbunden, so dass bei einer Rotation der Welle des Elektromotors ebenfalls die Kupplungseinrichtung 4 und damit auch der damit verbundene Walzenmitnehmer 3 rotiert. An dem der Kupplungseinrichtung 4 abgewandten Endbereich ist die Reinigungswalze 2 mit einem Lager 5 verbunden, welches hier beispielsweise als Kugellager ausgebildet ist und somit die Rotation der Reinigungswalze 2 ermöglicht. Auf der Umfangsfläche der Reinigungswalze 2 ist ein Walzenbelag 15 angeordnet, welcher als Schwammkörper und/oder Reinigungstuch oder ähnliches ausgebildet sein kann.The Walzenmitnehmer 3 carries on its peripheral surface a Walzenmitnehmerfeder 9, which is designed here as a helical spring. The Walzenmitnehmerfeder 9 is form-fitting to the Walzenmitnehmer 3, so that a coaxial centering is given. At the coupling means 8 opposite side of the Walzenmitnehmer 3 coupling elements 12, which are in engagement with coupling elements 11 of the coupling device 4. The coupling elements 11, 12 are as formcorresponding Formed projections, so that a torque can be transmitted from the coupling device 4 on the Walzenmitnehmer 3. The coupling device 4 is connected by means of the toothed belt 14 with the electric motor of the cleaning device 1, so that upon rotation of the shaft of the electric motor also the coupling device 4 and thus also the associated Walzenmitnehmer 3 rotates. At the end region facing away from the coupling device 4, the cleaning roller 2 is connected to a bearing 5, which is designed here for example as a ball bearing and thus enables the rotation of the cleaning roller 2. On the peripheral surface of the cleaning roller 2, a roller covering 15 is arranged, which may be formed as a sponge body and / or cleaning cloth or the like.

Figur 4 zeigt die Kupplungseinrichtung 4, welche zur drehmoment-übertragenden Verbindung mit dem Walzenmitnehmer 3 dient. Zu erkennen sind die Kupplungselemente 11, welche zur formkorrespondierenden Verbindung mit den Kupplungselementen 12 des Walzenmitnehmers 3 ausgebildet sind. Die gezeigte Kupplungseinrichtung 4 ist nur exemplarisch. Grundsätzlich können auch andere Arten von Kupplungseinrichtungen 4 vorgesehen sein, welche eine Drehmomentübertrag ermöglichen und zudem als Lager für den Walzenmitnehmer 3 in dem Reinigungsgerät geeignet sind. FIG. 4 shows the coupling device 4, which serves for the torque-transmitting connection with the Walzenmitnehmer 3. Evident are the coupling elements 11, which are formed for form-matching connection with the coupling elements 12 of the Walzenmitnehmers 3. The coupling device 4 shown is only an example. In principle, other types of coupling devices 4 may be provided, which allow a torque transfer and are also suitable as a bearing for the Walzenmitnehmer 3 in the cleaning device.

Die Figuren 5 und 6 zeigen zwei unterschiedliche Ansichten des Walzenmitnehmers 3. Figur 5 zeigt insbesondere die vier Kupplungsmittel 8, welche in einem Querschnitt des Walzenmitnehmers 3 im Wesentlichen auf einer Kreisbahn angeordnet sind. Figur 6 zeigt insbesondere den der Kulisse abgewandten Endbereich des Walzenmitnehmers 3, an welchem die Kupplungselemente 12 zur drehmomentübertragenden Verbindung mit den Kupplungselementen 11 der Kupplungseinrichtung 4 angeordnet sind.The FIGS. 5 and 6 show two different views of Walzenmitnehmers 3rd FIG. 5 shows in particular the four coupling means 8, which are arranged in a cross section of the Walzenmitnehmers 3 substantially on a circular path. FIG. 6 shows, in particular, the end portion of the roller cam 3 facing away from the link, on which the coupling elements 12 are arranged for torque-transmitting connection with the coupling elements 11 of the coupling device 4.

Die Erfindung funktioniert nun so, dass ein Nutzer des Reinigungsgerätes 1 für eine Installation einer Reinigungswalze 2 in dem Reinigungsgerät 1 den Walzenmitnehmer 3 in die Walzenaussparung 6 der Reinigungswalze 2 einführt. Dadurch wird die den Walzenmitnehmer 3 umgebende Walzenmitnehmerfeder 9 gespannt, so dass sich die Rückstellkraft bei fortschreitender axialer Bewegung des Walzenmitnehmers 3 erhöht. Die axiale Verschiebung wird soweit fortgesetzt, bis sich die Kupplungsmittel 8 des Walzenmitnehmers 3 über das Kupplungsmittel 7 der Reinigungswalze 2 schieben und schließlich dahinter verrasten. Im gezeigten Fall weisen die Kupplungsmittel 8 des Walzenmitnehmers 3 eine pfeilförmige Flanke auf, um das Überwinden des Kupplungsmittels 7 der Reinigungswalze 2 zu erleichtern. In dieser Stellung befindet sich das Kupplungsmittel 7 der Reinigungswalze 2 in axialer Richtung der Reinigungswalze 2 zwischen der Walzenmitnehmerfeder 9 und dem korrespondierenden Kupplungsmittel 8 des Walzenmitnehmers 3. Dadurch drückt die Walzenmitnehmerfeder 9 mit ihrer Rückstellkraft gegen das Kupplungsmittel 7 der Reinigungswalze 2 und an dem gegenüberliegenden Endbereich des Walzenmitnehmers 3 in Richtung der Kupplungseinrichtung 4, so dass die Kupplungselemente 11, 12 zur Drehmomentübertragung bereitstehen. Die Reinigungswalze 2 kann nunmehr mittels der Welle des Elektromotors rotiert werden.The invention now works so that a user of the cleaning device 1 for installation of a cleaning roller 2 in the cleaning device 1, the Walzenmitnehmer 3 in the roller recess 6 of the cleaning roller 2 introduces. As a result, the Walzenmitnehmerfeder 9 surrounding the Walzenmitnehmer 3 is tensioned, so that the restoring force increases as the axial movement of the Walzenmitnehmers 3 progresses. The axial displacement is continued until the coupling means 8 of the Walzenmitnehmers 3 slide over the coupling means 7 of the cleaning roller 2 and finally lock behind it. In the case shown, the coupling means 8 of the Walzenmitnehmers 3 an arrow-shaped edge to facilitate the overcoming of the coupling means 7 of the cleaning roller 2. In this position, the coupling means 7 of the cleaning roller 2 is in the axial direction of the cleaning roller 2 between the Walzenmitnehmerfeder 9 and the corresponding coupling means 8 of the Walzenmitnehmers 3. Thus, the Walzenmitnehmerfeder 9 presses with its restoring force against the coupling means 7 of the cleaning roller 2 and at the opposite end of Walzenmitnehmers 3 in the direction of the coupling device 4, so that the coupling elements 11, 12 are ready for torque transmission. The cleaning roller 2 can now be rotated by means of the shaft of the electric motor.

Zur Demontage der Reinigungswalze 2, beispielsweise für einen Austausch einer mit Schmutz belegten Reinigungswalze 2, ergreift der Nutzer des Reinigungsgerätes 1 die Reinigungswalze 2 und verschiebt diese axial in Richtung der Kupplungseinrichtung 4, so dass die Walzenmitnehmerfeder 9 weiter gestaucht wird und sich der Walzenmitnehmer 3 tiefer in die Walzenaussparung 6 der Reinigungswalze 2 hineinbewegt. Dadurch wird das Kupplungsmittel 8 des Walzenmitnehmers 3 von dem Kupplungsmittel 7 der Reinigungswalze 2 beabstandet, so dass die Gesamtlänge von Reinigungswalze 2 und Walzenmitnehmer 3 reduziert wird und die Reinigungswalze 2 mitsamt des Walzenmitnehmers 3 aus dem Reinigungsgerät 1 entnommen werden kann. Dies erfolgt in Richtung der Rückstellkraft der Walzenmitnehmerfeder 9. Es empfiehlt sich, die Kupplungselemente 11, 12 der Kupplungseinrichtung 4 und des Walzenmitnehmers 3 voneinander zu trennen, so dass die Reinigungswalze 2 zwischen der Kupplungseinrichtung 4 und dem Lager 5 entnommen werden kann. Ebenso ist es alternativ oder zusätzlich selbstverständlich auch möglich, eine Entnahme der Reinigungswalze 2 aus dem Reinigungsgerät 1 durch eine Trennung des der Kupplungseinrichtung 4 gegenüberliegenden Endbereiches der Reinigungswalze 2 von dem korrespondierenden Lager 5 zu bewirken.To disassemble the cleaning roller 2, for example, for replacement of a cleaning roller 2 occupied with dirt, the user of the cleaning device 1 takes the cleaning roller 2 and moves it axially in the direction of the coupling device 4, so that the Walzenmitnehmerfeder 9 is further compressed and the Walzenmitnehmer 3 deeper moved into the roller recess 6 of the cleaning roller 2. Thereby, the coupling means 8 of the Walzenmitnehmers 3 is spaced from the coupling means 7 of the cleaning roller 2, so that the total length of cleaning roller 2 and Walzenmitnehmer 3 is reduced and the cleaning roller 2 together with the Walzenmitnehmers 3 can be removed from the cleaning device 1. This is done in the direction of the restoring force of Walzenmitnehmerfeder 9. It is advisable to separate the coupling elements 11, 12 of the coupling device 4 and the Walzenmitnehmers 3 from each other, so that the cleaning roller 2 between the coupling device 4 and the bearing 5 can be removed. Likewise, it is alternatively or additionally of course also possible to effect removal of the cleaning roller 2 from the cleaning device 1 by separating the end region of the cleaning roller 2 opposite the coupling device 4 from the corresponding bearing 5.
