Description

Die Erfindung betrifft eine Reinigungsvorrichtung für eine Bodenreinigungsmaschine nach dem Oberbegriff von Anspruch 1.The invention relates to a cleaning device for a floor cleaning machine according to the preamble of claim 1.

Außerdem betrifft die Erfindung eine Bodenreinigungsmaschine, umfassend mindestens eine Reinigungsvorrichtung.Moreover, the invention relates to a floor cleaning machine, comprising at least one cleaning device.

Reinigungsvorrichtungen der eingangs genannten Art kommen zur Reinigung einer Bodenfläche zum Einsatz. Sie sind an einer Bodenreinigungsmaschine angeordnet, und zur Reinigung der Bodenfläche werden die Bürstenwalzen motorisch in Drehung versetzt. Die Bürstenwalzen sind jeweils an einem Gehäuseseitenteil eines Bürstengehäuses und an einem Gegenlagerteil drehbar gehalten. Die Gegenlagerteile werden häufig durch am Gehäusemittelteil gehaltene seitliche Abstreifglieder zum Abstreifen der zu reinigenden Bodenfläche gebildet. Dies hat sich als ungünstig für die Lagerung der Bürstenwalzen erwiesen, weil Unebenheiten der zu reinigenden Bodenfläche von den seitlichen Abstreifgliedern erfasst werden können. Dies kann zu unerwünschtem Wackeln der Bürstenwalzen führen.Cleaning devices of the type mentioned are used for cleaning a floor surface for use. They are arranged on a floor cleaning machine, and for cleaning the bottom surface, the brush rollers are rotated by a motor. The brush rollers are each rotatably supported on a housing side part of a brush housing and on an abutment part. The counter-bearing parts are often formed by held on the middle part of the side stripping members for stripping the floor surface to be cleaned. This has proved to be unfavorable for the storage of the brush rollers, because unevenness of the floor surface to be cleaned can be detected by the lateral Abstreifgliedern. This can lead to unwanted wobble of the brush rollers.

Die WO 2007/047856 A2 , welche den Oberbegriff des unabhängigen Anspruchs 1 beschreibt, zeigt eine Bodenreinigungsmaschine mit einer zwei Bürstenwalzen umfassenden Reinigungsvorrichtung, wobei jede Bürstenwalze mit einem ersten stirnseitigen Ende an einem von zwei unterschiedlich ausgestalteten Gehäuseseitenteilen und einem zweiten stirnseitigen Ende an einem mit dem Gehäuseseitenteil verbunden Gegenlagerteil gelagert ist.The WO 2007/047856 A2 , which describes the preamble of independent claim 1, shows a floor cleaning machine with a two brush rollers comprising cleaning device, each brush roller is mounted with a first end face on one of two differently designed housing side parts and a second end face on a bearing housing part connected to the counterpart bearing part.

Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Reinigungsvorrichtung und eine gattungsgemäße Bodenreinigungsmaschine bereitzustellen, deren Bürstenwalzen stabiler gelagert sind.Object of the present invention is to provide a generic cleaning device and a generic floor cleaning machine, the brush rollers are stored more stable.

Diese Aufgabe wird bei einer Reinigungsvorrichtung der eingangs genannten Art durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst.This object is achieved in a cleaning device of the type mentioned by the features of the characterizing part of claim 1.

Die erfindungsgemäße Reinigungsvorrichtung umfasst zwei Bürstenwalzen. Die erste Bürstenwalze ist mit ihrer ersten Stirnseite an dem ersten Gehäuseseitenteil und mit ihrer zweiten Stirnseite an dem ersten Gegenlagerteil gelagert. Die zweite Bürstenwalze ist mit ihrer ersten Stirnseite an dem zweiten Gehäuseseitenteil und mit ihrer zweiten Stirnseite an dem zweiten Gegenlagerteil gelagert. Das erste Gegenlagerteil ist an dem zweiten Gehäuseseitenteil gehalten und das zweite Gegenlagerteil an dem ersten Gehäuseseitenteil. Infolgedessen ist die erste Bürstenwalze mittelbar auch an dem zweiten Gehäuseseitenteil gelagert, und die zweite Bürstenwalze ist mittelbar auch an dem ersten Gehäuseseitenteil gelagert. Eine Lagerung der Bürstenwalzen an an sich funktionsfremden Gegenlagerteilen in Form von seitlichen Abstreifgliedern, wie dies bei den aus dem Stand der Technik bekannten gattungsgemäßen Reinigungsvorrichtungen der Fall ist, wird dadurch vermieden. Stattdessen können die Gegenlagerteile gezielt hinsichtlich der Stabilität der Lagerung der Bürstenwalzen optimiert werden. Dadurch kann insgesamt eine stabilere Lagerung der Bürstenwalzen erreicht werden.The cleaning device according to the invention comprises two brush rollers. The first brush roller is mounted with its first end face on the first housing side part and with its second end face on the first abutment part. The second brush roller is mounted with its first end side on the second housing side part and with its second end side on the second abutment part. The first abutment part is held on the second housing side part and the second abutment part on the first housing side part. As a result, the first brush roller is also indirectly supported on the second housing side part, and the second brush roller is also indirectly supported on the first housing side part. A storage of the brush rollers on non-functional counter-bearing parts in the form of lateral Abstreifgliedern, as is the case with the generic cleaning devices known from the prior art, is thereby avoided. Instead, the abutment parts can be optimized specifically with regard to the stability of the storage of the brush rollers. As a result, a more stable storage of the brush rollers can be achieved overall.

Die identische Ausbildung der Gehäuseseitenteile ermöglicht es, die Herstellungskosten für die Reinigungsvorrichtung gering zu halten. Für eine weitere Reduzierung der Herstellungskosten der Reinigungsvorrichtung ist es günstig, wenn die Gegenlagerteile ebenfalls identisch ausgebildet sind.The identical design of the housing side parts makes it possible to keep the manufacturing costs for the cleaning device low. For a further reduction of the manufacturing cost of the cleaning device, it is advantageous if the counter-bearing parts are also formed identically.

Eine besonders stabile Lagerung der Bürstenwalzen kann erzielt werden, wenn die Gegenlagerteile als Druckgussteile ausgebildet sind. Vorzugsweise sind sie aus einem Metall, zum Beispiel aus Aluminium oder einer Aluminiumlegierung, gefertigt.A particularly stable mounting of the brush rollers can be achieved if the abutment parts are designed as die-cast parts. Preferably, they are made of a metal, for example aluminum or an aluminum alloy.

Von Vorteil ist es, wenn die Gehäuseseitenteile als Druckgussteile ausgebildet sind, denn dies erlaubt es, die Stabilität der Lagerung der Bürstenwalzen weiter zu steigern. Vorteilhafterweise sind die Gehäuseseitenteile aus einem Metall, beispielsweise aus Aluminium oder einer Aluminiumlegierung, gefertigt.It is advantageous if the housing side parts are formed as die-cast parts, because this makes it possible to further increase the stability of the bearing of the brush rollers. Advantageously, the housing side parts are made of a metal, for example aluminum or an aluminum alloy.

Günstig ist es, wenn das Gehäusemittelteil zumindest teilweise einen Hohlkörper ausbildet mit einer Deckenwand und einer Bodenwand. Dies erlaubt es, dem Gehäusemittelteil eine hohe Steifheit zu verleihen, wobei es gleichzeitig gewichtsarm ausgebildet werden kann. Auf diese Weise kann dann auch dem Bürstengehäuse und damit der Reinigungsvorrichtung eine hohe Steifheit verliehen werden. Der von dem Gehäusemittelteil ausgebildete Hohlkörper kann beispielsweise oberhalb des Bürstenraumes angeordnet sein, wobei die Bodenwand des Hohlkörpers eine den Bürstenraum obenseitig begrenzende Wand darstellt. Die Deckenwand des Hohkörpers kann beispielsweise durch eine Deckenwand des Gehäusemittelteils gebildet sein. Zur weiteren Versteifung des Gehäusemittelteiles kann der Hohlkörper durch Zwischenwände in einzelne Abschnitte unterteilt sein.It is advantageous if the middle part of the housing at least partially forms a hollow body with a top wall and a bottom wall. This makes it possible to give the middle part of a high stiffness, while it can be formed simultaneously low in weight. In this way, a high rigidity can then also be imparted to the brush housing and thus to the cleaning device. The hollow body formed by the middle part of the housing may, for example, be arranged above the brush space, the bottom wall of the hollow body being a wall bordering the brush space on the top. The ceiling wall of the Hohkörpers may be formed for example by a ceiling wall of the middle part. For further stiffening of the housing middle part of the hollow body may be divided by partitions into individual sections.

Vorzugsweise bildet der Hohlkörper einen Aufnahmeraum für mindestens einen Antriebsmotor für die Bürstenwalzen. Der Aufnahmeraum ist beispielsweise über eine einem Gehäuseseitenteil zugewandte Öffnung zugänglich, durch die der mindestens eine Antriebsmotor in den Aufnahmeraum eingeführt werden kann. Eine von dem mindestens einen Antriebsmotor angetriebene Antriebswelle kann die Öffnung durchgreifen, um die an dem Gehäuseseitenteil gelagerte Bürstenwalze anzutreiben.Preferably, the hollow body forms a receiving space for at least one drive motor for the brush rollers. The receiving space is accessible for example via a housing side part facing opening through which the at least one drive motor can be introduced into the receiving space. A driven by the at least one drive motor drive shaft can pass through the opening to drive the mounted on the housing side part brush roller.

Bevorzugt ist jeder Bürstenwalze ein eigener Antriebsmotor zugeordnet.Preferably, each brush roller is assigned its own drive motor.

Günstig ist es, wenn das Gehäusemittelteil als Kunststoffformteil ausgebildet ist. Dies ermöglicht eine kostengünstige Herstellung des Gehäusemittelteiles. Bildet das Gehäusemittelteil wie vorstehend beschrieben zumindest teilweise einen Hohlkörper, so lässt sich dieser auf technisch einfache Weise fertigen, wenn das Gehäusemittelteil als Kunststoffformteil ausgebildet ist.It is advantageous if the middle part of the housing is designed as a plastic molded part. This allows a cost-effective production of the housing middle part. If, as described above, the housing middle part at least partially forms a hollow body, then this can be manufactured in a technically simple manner if the housing middle part is designed as a plastic molded part.

Günstigerweise ist jedes Gegenlagerteil von einer Betriebsstellung, in der es an einem Gehäuseseitenteil gehalten ist, in eine Entnahmestellung und umgekehrt überführbar, in der eine Bürstenwalze der Reinigungsvorrichtung entnehmbar ist. Eine derartige Ausführungsform erleichtert dem Benutzer die Handhabung der Reinigungsvorrichtung. Durch Überführen eines Gegenlagerteiles von der Betriebsstellung in die Entnahmestellung wird dem Benutzer die Möglichkeit gegeben, die am Gegenlagerteil gelagerte Bürstenwalze der Reinigungsvorrichtung zu entnehmen. Dies ist beispielsweise bei Verschleiß der Bürstenwalze erforderlich. Es kann vorgesehen sein, dass die Bürstenwalze gegen eine andersartige Bürstenwalze, die für die zu reinigende Bodenfläche in besonderer Weise ausgebildet und geeignet ist, austauschbar ist. Nach dem Austausch der Bürstenwalze kann das Gegenlagerteil von der Entnahmestellung in die Betriebsstellung überführt und der Betrieb der Bodenreinigungsmaschine wieder aufgenommen werden.Conveniently, each abutment part of an operating position in which it is held on a housing side part, in a removal position and vice versa, in which a brush roller of the cleaning device can be removed. Such an embodiment facilitates the handling of the cleaning device for the user. By transferring an abutment part from the operating position into the removal position, the user is given the opportunity to remove the brush roller mounted on the abutment part of the cleaning device. This is necessary, for example, when the brush roller is worn. It can be provided that the brush roller against a different type of brush roller, for the floor surface to be cleaned in specially adapted and suitable, is interchangeable. After replacement of the brush roller, the counter bearing part can be transferred from the removal position to the operating position and the operation of the floor cleaning machine can be resumed.

Bevorzugt weisen die Gegenlagerteile und die Gehäuseseitenteile zusammenwirkende Ausrichtglieder zum Ausrichten der Gegenlagerteile relativ zu den Gehäuseseitenteilen auf. Dies vereinfacht einem Benutzer die Anordnung der Gegenlagerteile am jeweiligen Gehäuseseitenteil, etwa beim erstmaligen Zusammenbau der Reinigungsvorrichtung oder beim Überführen der Gegenlagerteile von der Entnahmestellung in die Betriebsstellung, und sichert so eine korrekte Ausrichtung der Gegenlagerteile relativ zu den Gehäuseseitenteilen.Preferably, the abutment parts and the housing side parts have cooperating alignment members for aligning the abutment parts relative to the housing side parts. This simplifies a user the arrangement of the abutment parts on the respective housing side part, such as when first assembling the cleaning device or when transferring the abutment parts from the removal position to the operating position, and thus ensures a correct alignment of the abutment parts relative to the housing side parts.

Vorzugsweise umfasst die Reinigungsvorrichtung mindestens eine erste Verriegelungseinrichtung zur Sicherung der Anordnung jedes Gegenlagerteiles an einem Gehäuseseitenteil, wobei die mindestens eine erste Verriegelungseinrichtung ein am Gehäuseseitenteil angeordnetes erstes Verriegelungsglied aufweist, das mit einem am Gegenlagerteil angeordneten zweiten Verriegelungsglied zusammenwirkt. Dadurch kann sichergestellt werden, dass sich das Gegenlagerteil nicht unerwünscht vom Gehäuseseitenteil löst.Preferably, the cleaning device comprises at least one first locking device for securing the arrangement of each abutment member on a housing side part, wherein the at least one first locking means comprises a housing arranged on the first part of the first locking member which cooperates with a arranged on the abutment member second locking member. This can ensure that the abutment member does not dissolve undesirable from the housing side part.

Die mindestens eine erste Verriegelungseinrichtung lässt sich konstruktiv einfach ausbilden, wenn sie von einer Verriegelungsstellung, in der das erste und das zweite Verriegelungsglied miteinander in Eingriff stehen, in eine Lösestellung und umgekehrt überführbar ist, in der das erste und das zweite Verriegelungsglied außer Eingriff stehen.The at least one first locking device can be structurally simple if it can be transferred from a locking position, in which the first and the second locking member engage with each other, into a release position and vice versa, in which the first and the second locking member are disengaged.

Eine besonders benutzerfreundliche Handhabung der Reinigungsvorrichtung kann erzielt werden, wenn die mindestens eine erste Verriegelungseinrichtung durch Drehen mindestens eines Verriegelungsgliedes von der Verriegelungsstellung in die Lösestellung und umgekehrt überführbar ist. Hierfür können beispielsweise das erste und/oder das zweite Verriegelungsglied drehbar am Gehäuseseitenteil bzw. am Gegenlagerteil gelagert sein.A particularly user-friendly handling of the cleaning device can be achieved if the at least one first locking device can be moved by rotating at least one locking member from the locking position to the release position and vice versa. For this example, the first and / or the second locking member can be rotatably mounted on the housing side part or on the abutment member.

Von Vorteil ist es, wenn mindestens ein Verriegelungsglied einen Drehgriff aufweist. Am Drehgriff kann ein Benutzer das Verriegelungsglied ergreifen, um es von einer Verriegelungsstellung in eine Lösestellung und umgekehrt zu überführen.It is advantageous if at least one locking member has a turning handle. On the turning handle, a user can grasp the locking member to transfer it from a locking position to a release position and vice versa.

Günstig ist es, wenn das erste und das zweite Verriegelungsglied miteinander verrastbar sind. Dadurch ist auf technisch einfache Weise die Möglichkeit gegeben, einen bestehenden Eingriff zwischen dem ersten und dem zweiten Verriegelungsglied zu sichern.It is advantageous if the first and the second locking member are latched together. This provides a technically simple way to secure an existing engagement between the first and the second locking member.

Bevorzugt ist die mindestens eine erste Verriegelungseinrichtung werkzeuglos betätigbar. Damit ist die Reinigungsvorrichtung besonders benutzerfreundlich handhabbar. Das jeweilige Gegenlagerteil kann so werkzeuglos ent- oder verriegelt werden.Preferably, the at least one first locking device can be actuated without tools. Thus, the cleaning device is particularly user-friendly to handle. The respective counter bearing part can be unlocked or locked without tools.

Vorteilhafterweise weist die Reinigungsvorrichtung zwei seitliche Abstreifglieder zum Abstreifen der zu reinigenden Bodenfläche auf. Mittels der Abstreifglieder kann abgelöster Schmuz und Reinigungsflüssigkeit von der Bodenfläche abgestreift werden, so dass der abgelöste Schmutz nicht seitlich über die Begrenzungen der Reinigungsvorrichtung hinaus gelangt.Advantageously, the cleaning device has two lateral wiper members for stripping the floor surface to be cleaned. By means of the wiper members, peeled mold and cleaning liquid can be wiped off the bottom surface, so that the detached dirt does not pass laterally beyond the boundaries of the cleaning device.

Die Abstreifglieder können am Bürstengehäuse beweglich gelagert sein und beispielsweise von einer Betriebsstellung, in der sie am Bürstengehäuse anliegen, in eine Wartungsstellung und umgekehrt überführbar sein, bei der dem Benutzer ein Zugang zu den Gegenlagerteilen ermöglicht wird.The wiper members may be movably mounted on the brush housing and, for example, from an operating position in which they bear against the brush housing, in a maintenance position and vice versa be transferred, in which the user access to the abutment parts is made possible.

Von Vorteil ist es, wenn die Reinigungsvorrichtung mindestens eine zweite Verriegelungseinrichtung zur Sicherung der Anordnung jedes Abstreifgliedes am Bürstengehäuse umfasst. Dadurch kann sichergestellt werden, dass sich die Abstreifglieder nicht unerwünscht vom Bürstengehäuse lösen.It is advantageous if the cleaning device comprises at least one second locking device for securing the arrangement of each wiper member on the brush housing. As a result, it can be ensured that the wiper members do not detach undesirably from the brush housing.

Die mindestens eine zweite Verriegelungseinrichtung umfasst günstigerweise ein erstes Verriegelungsglied, das am Bürstengehäuse, insbesondere an einem Gehäuseseitenteil angeordnet ist, und das mit einem an einem Abstreifglied angeordneten zweiten Verriegelungsglied zusammenwirkt.The at least one second locking device conveniently comprises a first locking member which is arranged on the brush housing, in particular on a housing side part, and which cooperates with a second locking member arranged on a stripping member.

Die mindestens eine zweite Verriegelungseinrichtung ist bevorzugt in entsprechender Weise wie die vorstehend beschriebene mindestens eine erste Verriegelungseinrichtung von einer Verriegelungsstellung, in der das erste und das zweite Verriegelungsglied der mindestens einen zweiten Verriegelungseinrichtung miteinander in Eingriff stehen, in eine Lösestellung und umgekehrt überführbar, in der das erste und das zweite Verriegelungsglied außer Eingriff stehen.The at least one second locking device is preferably in a manner similar to the above-described at least one first locking device from a locking position in which the first and the second locking member of the at least one second locking means are engaged with each other, into a release position and vice versa, in which the first and the second locking member are disengaged.

Durch Überführen der mindestens einen zweiten Verriegelungseinrichtung von der Verriegelungsstellung in die Lösestellung kann ein Abstreifglied entriegelt werden, beispielsweise um es von einer Betriebsstellung in eine Wartungsstellung zu überführen. Hierbei ist die mindestens eine zweite Verriegelungseinrichtung insbesondere durch Drehen mindestens eines Verriegelungsgliedes von der Verriegelungsstellung in die Lösestellung und umgekehrt überführbar. Das erste und/oder das zweite Verriegelungsglied der mindestens einen zweiten Verriegelungseinrichtung können hierfür zum Beispiel drehbar an einem Abstreifglied oder am Bürstengehäuse, insbesondere am Gehäuseseitenteil, gelagert sein.By transferring the at least one second locking device from the locking position into the release position, a wiper member can be unlocked, for example, from an operating position into a service position to convict. In this case, the at least one second locking device can be transferred in particular by turning at least one locking member from the locking position into the release position and vice versa. For this purpose, the first and / or the second locking member of the at least one second locking device can for example be rotatably mounted on a stripping member or on the brush housing, in particular on the housing side part.

Günstig ist es, wenn mindestens ein Verriegelungsglied der mindestens einen zweiten Verriegelungseinrichtung einen Drehgriff aufweist, um ein Drehen des mindestens einen Verriegelungsgliedes zu erleichtern.It is advantageous if at least one locking member of the at least one second locking device has a rotary handle in order to facilitate rotation of the at least one locking member.

Es ist von Vorteil, wenn das erste und das zweite Verriegelungsglied der mindestens einen zweiten Verriegelungseinrichtung miteinander verrastbar sind, um einen bestehenden Eingriff zu sichern.It is advantageous if the first and the second locking member of the at least one second locking device can be locked together to secure an existing engagement.

Insbesondere ist es von Vorteil, wenn die mindestens eine zweite Verriegelungseinrichtung werkzeuglos betätigbar ist, denn dies erleichtert einem Benutzer die Handhabung der Reinigungsvorrichtung.In particular, it is advantageous if the at least one second locking device can be actuated without tools, because this facilitates the handling of the cleaning device for a user.

Bevorzugt weist die Reinigungsvorrichtung eine Mehrzahl von identisch ausgebildeten Verriegelungsgliedern zur Sicherung der Anordnung der Gegenlagerteile an den Gehäuseseitenteilen und/oder von Abstreifgliedern zum Abstreifen einer zu reinigenden Bodenfläche am Bürstengehäuse auf. Durch die Verwendung einer Mehrzahl von identisch ausgebildeten Verriegelungsgliedern lassen sich die Herstellungskosten für die Reinigungsvorrichtung reduzieren. Darüber hinaus wird einem Benutzer die Handhabung der Reinigungsvorrichtung erleichtert, weil er sich mit einer geringeren Anzahl von Verriegelungsgliedern vertraut zu machen braucht.Preferably, the cleaning device has a plurality of identically formed locking members for securing the arrangement of the abutment parts on the housing side parts and / or wiper members for stripping a floor surface to be cleaned on the brush housing. By using a plurality of identically designed locking members, the manufacturing costs for the cleaning device can be reduced. In addition, a user is facilitated the handling of the cleaning device, because he needs to familiarize himself with a smaller number of locking members.

Günstig ist es, wenn die Gehäuseseitenteile eine Mehrzahl von Aufnahmen für Verriegelungsglieder, die zur Sicherung der Anordnung der Gegenlagerteile an den Gehäuseseitenteilen und/oder von Abstreifgliedern zum Abstreifen einer zu reinigenden Bodenfläche am Bürstengehäuse vorgesehen sind, aufweisen. Dies gibt die Möglichkeit, sowohl die Gegenlagerteile als auch die Abstreifglieder an den Gehäuseseitenteilen zu verriegeln. Insbesondere kann vorgesehen sein, dass die Gehäuseseitenteile Aufnahmen für sämtliche Verriegelungsglieder der Reinigungsvorrichtung, die zur Sicherung der Anordnung der Gegenlagerteile an den Gehäuseseitenteilen und/oder von Abstreifgliedern am Bürstengehäuse erforderlich sind, aufweisen.It is advantageous if the housing side parts have a plurality of receptacles for locking members, which are provided for securing the arrangement of the abutment parts on the housing side parts and / or Abstreifgliedern for stripping a floor surface to be cleaned on the brush housing. This makes it possible to lock both the counter bearing parts and the wiper members on the housing side parts. In particular, it may be provided that the housing side parts recordings for all locking members of the cleaning device, which are required to secure the arrangement of the abutment parts on the housing side parts and / or wiper members on the brush housing.

Von Vorteil ist es, wenn jedem Gehäuseseitenteil ein Abdeckglied zum Abdecken des Gehäuseseitenteiles auf seiner dem Bürstenraum abgewandten Seite zugeordnet ist. Durch die Abdeckglieder können die Gehäuseseitenteile vor Schmutz und Reinigungsflüssigkeit geschützt werden. Dies ist insbesondere dann von Vorteil, wenn an den Gehäuseseitenteilen eine Antriebseinrichtung für die Bürstenwalze gehalten ist, da diese dann ebenfalls vor Schmutz und Reinigungsflüssigkeit geschützt werden kann.It is advantageous if each housing side part is assigned a cover member for covering the housing side part on its side facing away from the brush space. Through the cover members, the housing side parts can be protected from dirt and cleaning fluid. This is particularly advantageous if a drive device for the brush roller is held on the housing side parts, since then they can also be protected from dirt and cleaning fluid.

Besonders günstig ist es, wenn die Abdeckglieder mit mindestens einem Verriegelungsglied verrastbar sind, mit dem die Anordnung eines Gegenlagerteiles an einem Gehäuseseitenteil und/oder eines Abstreifgliedes zum Abstreifen einer zu reinigenden Bodenfläche am Bürstengehäuse sicherbar ist. Dies gibt beispielsweise die Möglichkeit, dass das mindestens eine Verriegelungsglied relativ zu einem Abdeckglied definierte Stellungen einnehmen kann. Beispielsweise kann vorgesehen sein, dass das mindestens eine Verriegelungsglied eine Verriegelungsstellung und eine Lösestellung einnehmen kann, in denen es jeweils mit einem Abdeckglied verrastet. Dies sichert die Lage des mindestens einen Verriegelungsgliedes in der Verriegelungsstellung und in der Lösestellung und damit die Anordnung der Gegenlagerteile an den Gehäuseseitenteilen und/oder der Abstreifglieder am Bürstengehäuse.It is particularly advantageous if the cover members can be latched with at least one locking element with which the arrangement of an abutment part on a housing side part and / or a stripping member for stripping a floor surface to be cleaned on the brush housing can be secured. This gives for example the possibility that the at least one locking member relative to a cover member defined positions can take. For example, it can be provided that the at least one locking member can assume a locking position and a release position, in which it is locked in each case with a cover member. This ensures the position of the at least one locking member in the locking position and in the release position and thus the arrangement of the abutment parts on the housing side parts and / or the wiper members on the brush housing.

Wie eingangs erwähnt, betrifft die Erfindung auch eine Bodenreinigungsmaschine, umfassend mindestens eine Reinigungsvorrichtung.As mentioned above, the invention also relates to a floor cleaning machine comprising at least one cleaning device.

Bei einer derartigen Bodenreinigungsmaschine wird die eingangs genannte Aufgabe erfindungsgemäß dadurch gelöst, dass die mindestens eine Reinigungsvorrichtung wie vorstehend beschrieben ausgebildet ist.In such a floor cleaning machine, the object mentioned in the introduction is achieved according to the invention in that the at least one cleaning device is designed as described above.

Die erfindungsgemäße Bodenreinigungsmaschine weist damit die bereits im Zusammenhang mit den voranstehenden Erläuterungen der erfindungsgemäßen Reinigungsvorrichtung erwähnten Vorteile auf.The floor cleaning machine according to the invention thus has the advantages already mentioned in connection with the above explanations of the cleaning device according to the invention.

Eine bevorzugte Ausführungsform einer erfindungsgemäßen Bodenreinigungsmaschine ist in Figur 1 schematisch dargestellt und mit dem Bezugszeichen 10 belegt.A preferred embodiment of a floor cleaning machine according to the invention is in FIG. 1 shown schematically and occupied by the reference numeral 10.

Die Bodenreinigungsmaschine 10 trägt an ihrer Unterseite 12 eine erfindungsgemäße Reinigungsvorrichtung 14, welche zwei in Figur 1 gestrichelt dargestellte Bürstenwalzen 16 und 18 umfasst.The floor cleaning machine 10 carries on its underside 12 a cleaning device 14 according to the invention, which two in FIG. 1 Includes brush rollers 16 and 18 shown in dashed lines.

Die Reinigungsvorrichtung 14 kann in an sich bekannter und deswegen nicht erläuterter Weise auf eine zu reinigende Bodenfläche 24 abgesenkt werden. Zur Steigerung der Reinigungswirkung kann eine Reinigungsflüssigkeit, vorzugsweise Wasser, auf die Bodenfläche 24 aufgebracht werden, um diese von Schmutz zu befreien.The cleaning device 14 can be lowered in a manner known per se and therefore not explained on a bottom surface 24 to be cleaned. To increase the cleaning effect, a cleaning liquid, preferably water, be applied to the bottom surface 24 in order to rid it of dirt.

Zum Aufnehmen der schmutzigen Flüssigkeit, d. h. des Gemisches aus dem Schmutz und der Reinigungsflüssigkeit, der sogenannten Schmutzflotte, weist die Bodenreinigungsmaschine 10 an ihrer Rückseite 26 eine Schmutzaufnahmevorrichtung 28 auf, mit der die Schmutzflotte von der Bodenfläche 24 in bekannter Weise abgesaugt werden kann.For picking up the dirty liquid, ie the mixture of the dirt and the cleaning liquid, the so-called dirty liquor, the floor cleaning machine 10 has a dirt collecting device on its rear side 26 28, with the dirty liquor can be sucked from the bottom surface 24 in a known manner.

Wie in den Figuren 2 bis 6 erkennbar ist, weist die erfindungsgemäße Reinigungsvorrichtung 14 ein Bürstengehäuse 30 auf, das ein Gehäusemittelteil 32 und zwei identisch ausgebildete Gehäuseseitenteile umfasst, von denen in den Figuren 5 und 6 ein Gehäuseseitenteil 34 dargestellt ist.As in the FIGS. 2 to 6 can be seen, the cleaning device 14 according to the invention on a brush housing 30, which comprises a middle part 32 and two housing side parts of identical design, of which in the FIGS. 5 and 6 a housing side part 34 is shown.

Weil die Gehäuseseitenteile der Reinigungsvorrichtung 14 identisch ausgebildet sind, werden beide im Rahmen der folgenden Erläuterungen mit dem Bezugszeichen 34 referenziert. Erläuterungen, die sich auf nur ein Gehäuseseitenteil 34 beziehen, gelten damit für beide Gehäuseseitenteile der Reinigungsvorrichtung 14. Entsprechendes gilt für untenstehend beschriebene Gegenlagerteile 56 der Reinigungsvorrichtung 14.Because the housing side parts of the cleaning device 14 are identical, both are referenced by the reference numeral 34 in the following explanations. Explanations which refer to only one housing side part 34, thus apply to both housing side parts of the cleaning device 14. The same applies to the abutment parts 56 of the cleaning device 14 described below.

Das Gehäusemittelteil 32 ist als einstückiges Kunststoffformteil ausgebildet. Es umfasst eine Deckenwand 36, an der eine Haltevorrichtung 38 zur Befestigung der Reinigungsvorrichtung 14 an der Bodenreinigungsmaschine 10 fixiert ist, und eine Bodenwand 40. Die Deckenwand 36 und die Bodenwand 40 sind an einer Vorderseite 20 und nahe einer Rückseite 22 des Gehäusemittelteiles 32, bezogen auf eine Hauptbewegungsrichtung 41 der Bodenreinigungsmaschine 10, miteinander verbunden.The middle part 32 is formed as a one-piece plastic molded part. It comprises a ceiling wall 36 to which a holding device 38 for fixing the cleaning device 14 to the floor cleaning machine 10 is fixed, and a bottom wall 40. The ceiling wall 36 and the bottom wall 40 are on a front side 20 and near a rear side 22 of the middle part 32, based in a main movement direction 41 of the floor cleaning machine 10, connected to each other.

Darüber hinaus sind die Deckenwand 36 und die Bodenwand 40 über seitliche Wandabschnitte verbunden, von denen in Figur 4 nur ein seitlicher Wandabschnitt 42 gezeigt ist. Zwischen der Deckenwand 36 und der Bodenwand 40 ist ein Hohlraum 44 gebildet. Das Gehäusemittelteil 32 bildet auf diese Weise teilweise einen Hohlkörper und erlangt dadurch mit vergleichsweise geringem Gewicht eine hohe Steifheit. Zur weiteren Versteifung weist das Gehäusemittelteil 32 Zwischenwände 45a und 45b auf, die den Hohlraum 44 unterteilen und in Figur 4 durch gestrichelte Linien angedeutet sind.In addition, the ceiling wall 36 and the bottom wall 40 are connected by side wall sections, of which in FIG. 4 only a lateral wall section 42 is shown. Between the top wall 36 and the bottom wall 40, a cavity 44 is formed. The middle part 32 forms in this way partially a hollow body and thereby obtains a comparatively low weight high rigidity. For further stiffening, the middle part 32 has partitions 45a and 45b, which divide the cavity 44 and in FIG. 4 are indicated by dashed lines.

Der Hohlraum 44 ist über Einführöffnungen zugänglich, von denen in Figur 4 nur eine Einführöffnung 46, welche vom seitlichen Wandabschnitt 42 eingefasst wird, gezeigt ist.The cavity 44 is accessible via insertion openings, of which in FIG. 4 only an insertion opening 46, which is bordered by the lateral wall portion 42 is shown.

Der seitliche Wandabschnitt 42 dient als Anlageflansch für das Gehäuseseitenteil 34, das mit einer innenseitigen, d.h. dem Gehäusemittelteil 32 zugewandten Anlagefläche 48 (Figur 6) so an den seitlichen Wandabschnitt 42 angelegt werden kann, dass Durchbrechungen 50a bis 50e (Figuren 5 und 6) des Gehäuseseitenteiles 34 mit Aufnahmen für Befestigungsmittel im Gehäusemittelteil 32 fluchten, von denen in Figur 4 drei Aufnahmen 52a bis 52c gezeigt sind. Durch Einsatz von Befestigungsmitteln wie beispielsweise Schrauben lässt sich das Gehäuseseitenteil 34 mit dem Gehäusemittelteil 32 verbinden.The lateral wall section 42 serves as an abutment flange for the housing side part 34, which has an inner side, ie, the central part 32 facing the contact surface 48 (FIG. FIG. 6 ) can be applied to the lateral wall portion 42, that openings 50a to 50e ( FIGS. 5 and 6 ) of the housing side part 34 are aligned with receptacles for fastening means in the housing middle part 32, of which in FIG. 4 three shots 52a to 52c are shown. By using fastening means such as screws, the housing side part 34 can be connected to the housing middle part 32.

Sind die beiden Gehäuseseitenteile 34 mit dem Gehäusemittelteil 32 verbunden, bilden sie das bereits erwähnte Bürstengehäuse 30, welches einen Bürstenraum 54 teilweise begrenzt. Der Bürstenraum 54 wird obenseitig durch die Bodenwand 40 des Gehäusemittelteiles 32 und außenseitig durch die Gehäuseseitenteile 34 sowie durch an den Gehäuseseitenteilen 34 auf unten stehend beschriebene Weise gehaltene Gegenlagerteile 56 (Figuren 7 und 8) begrenzt.If the two housing side parts 34 are connected to the housing middle part 32, they form the already mentioned brush housing 30 which partially delimits a brush space 54. The brush space 54 is on the upper side by the bottom wall 40 of the housing middle part 32 and on the outside by the housing side parts 34 and held by the housing side parts 34 in the manner described below support abutment parts 56 (FIGS. FIGS. 7 and 8 ) limited.

Im Bürstenraum 54 sind die Bürstenwalzen 16 und 18 um Drehachsen 58 und 60 (Figur 3) gegenläufig an den Gehäuseseitenteilen 34 und den Gegenlagerteilen 56 auf nachfolgend beschriebene Weise drehbar gelagert.In the brush space 54, the brush rollers 16 and 18 about axes of rotation 58 and 60 (FIG. FIG. 3 ) rotatably mounted in opposite directions on the housing side parts 34 and the abutment members 56 in the manner described below.

Wie aus den Figuren 9 bis 11 unter Zuhilfenahme der Figuren 5 und 6 deutlich wird, ist an den Gehäuseseitenteilen 34 jeweils eine Antriebseinrichtung 62 zum Antreiben einer der Bürstenwalzen 16 und 18 angeordnet. Jede Antriebseinrichtung 62 umfasst einen Antriebsmotor 64 (in Figur 3 und in Figur 9 dargestellt), dessen Antriebswelle 66 über einen Treibriemen 68 eine Riemenscheibe 70 antreibt, die gemeinsam mit einem Drehmomentübertragungsglied 72 in Form eines Torxgliedes 74 (Figur 11) auf einer Abtriebswelle 76 montiert ist. Die Abtriebswelle 76 ist mittels eines an sich bekannten und deswegen nicht näher erläuterten Lagers, das in der Zeichnung nicht gezeigt ist, in einer Nabe 78 (Figur 6), welche in dem Gehäuseseitenteil 34 gebildet ist, gelagert.Like from the FIGS. 9 to 11 with the help of the FIGS. 5 and 6 becomes clear, in each case a drive means 62 for driving one of the brush rollers 16 and 18 is arranged on the housing side parts 34. Each drive device 62 comprises a drive motor 64 (in FIG FIG. 3 and in FIG. 9 shown), whose drive shaft 66 via a drive belt 68, a pulley 70 drives, which together with a torque transmitting member 72 in the form of a Torxgliedes 74 ( FIG. 11 ) is mounted on an output shaft 76. The output shaft 76 is by means of a known per se and therefore unspecified bearing, which is not shown in the drawing, in a hub 78 (FIG. FIG. 6 ), which is formed in the housing side part 34, stored.

Das Torxglied 74 greift auf an sich bekannte und deswegen nicht näher erläuterte Weise stirnseitig in eine der Bürstenwalzen 16 oder 18 zu deren Lagerung am Gehäuseseitenteil 34 ein und überträgt dadurch eine von dem Antriebsmotor 64 hervorgerufene Drehbewegung auf die Bürstenwalzen 16 bzw. 18.The Torxglied 74 engages on a known per se and therefore unspecified manner frontally into one of the brush rollers 16 or 18 for their storage on the housing side part 34 and thereby transmits caused by the drive motor 64 rotational movement of the brush rollers 16 and 18th

Der Antriebsmotor 64 ist mit Hilfe von in der Zeichnung nicht dargestellten Befestigungsmitteln, welche Durchbrechungen 80a bis 80d (Figur 9) des Gehäuseseitenteiles 34 durchgreifen und in den Antriebsmotor 64 eingreifen, mit dem Gehäuseseitenteil 34 verbunden. Liegt das Gehäuseseitenteil 34 an dem seitlichen Wandabschnitt 42 des Gehäusemittelteiles 32 an, so ist der Antriebsmotor 64 in dem vom Gehäusemittelteil 32 gebildeten Hohlraum 44 angeordnet, in den er durch die Einführöffnung 46 hindurch eingeführt werden kann. Der Hohlraum 44 bildet auf diese Weise einen Aufnahmeraum für den Antriebsmotor 64, so dass dieser im Hohlraum 44 wirkungsvoll gegen Schmutz und Reinigungsflüssigkeit geschützt ist.The drive motor 64 is by means of fixing means, not shown in the drawing, which openings 80a to 80d ( FIG. 9 ) of the housing side part 34 and engage in the drive motor 64, connected to the housing side part 34. If the housing side part 34 abuts on the lateral wall section 42 of the housing middle part 32, the drive motor 64 is arranged in the cavity 44 formed by the housing middle part 32, in which it can be inserted through the insertion opening 46 therethrough. The cavity 44 thus forms a receiving space for the drive motor 64, so that it is effectively protected in the cavity 44 against dirt and cleaning fluid.

Wie bereits erwähnt, weist die Reinigungsvorrichtung 14 zur Lagerung der Bürstenwalzen 16 und 18 identisch ausgestaltete Gegenlagerteile 56 auf, die in den Figuren 7 und 8 gezeigt sind. Die Gegenlagerteile 56 umfassen einen in Seitenansicht näherungsweise halbkreisförmigen scheibenförmigen Abschnitt 82, von dem ein Rand 84 seitlich absteht. Die Gegenlagerteile 56 sind so bemessen, dass sie in von den Gehäuseseitenteilen 34 gebildeten und in Seitenansicht ebenfalls annäherungsweise halbkreisförmigen Aussparungen 86 anordenbar sind (Figuren 5 und 6 sowie 9 bis 11). Dabei liegt der Rand 84 des Gegenlagerteiles 56 an einer am Gehäuseseitenteil 34 gebildeten Anlagefläche 88 an.As already mentioned, the cleaning device 14 for supporting the brush rollers 16 and 18 identically configured abutment parts 56, which in the FIGS. 7 and 8 are shown. The abutment parts 56 include a side-view approximately semicircular disc-shaped portion 82, from which an edge 84 projects laterally. The abutment parts 56 are dimensioned such that they can be arranged in recesses 86 formed by the housing side parts 34 and likewise approximately semicircular in side view ( FIGS. 5 and 6 as well as 9 to 11). In this case, the edge 84 of the abutment part 56 bears against a contact surface 88 formed on the housing side part 34.

Zur Ausrichtung des Gegenlagerteiles 56 relativ zum Gehäuseseitenteil 34 weist das Gegenlagerteil 56 Ausrichtglieder in Form von vom Rand 84 abstehenden Rippen 90a bis 90j auf. Zwischen die Rippen 90a bis 90j können Ausrichtglieder in Form von Leisten 92a und 92b, die von der Anlagefläche 88 des Gehäuseseitenteiles 34 abstehen, eingreifen.For alignment of the abutment member 56 relative to the housing side part 34, the abutment member 56 on alignment members in the form of protruding from the edge 84 ribs 90a to 90j. Between the ribs 90a to 90j alignment members in the form of strips 92a and 92b, which protrude from the abutment surface 88 of the housing side part 34, engage.

Der scheibenförmige Abschnitt 82 weist eine zentrale Durchbrechung 93 auf, in der ein Lagerdorn 94 (Figur 11) so angeordnet ist, dass er in den Bürstenraum 54 hineinragt und lagernd in diejenige Stirnseite der Bürstenwalzen 16 oder 18 eingreift, die derjenigen gegenüberliegt, welche mittels des Torxgliedes 74 an dem gegenüberliegenden Gehäuseseitenteil 34 angetrieben wird.The disc-shaped section 82 has a central opening 93, in which a bearing mandrel 94 (FIG. FIG. 11 ) is arranged so that it protrudes into the brush space 54 and engages in stock in the end face of the brush rollers 16 or 18, which is opposite to that which is driven by means of the Torxgliedes 74 on the opposite housing side part 34.

Auf diese Weise sind die Bürstenwalzen 16 und 18 drehbar an den Gehäuseseitenteilen 34 und den Gegenlagerteilen 56 gelagert, wobei die Gegenlagerteile 56 auf unten stehend beschriebene Weise an den Gehäuseseitenteilen 34 gehalten sind. Dadurch weist die Lagerung der Bürstenwalzen 16 und 18 eine hohe Stabilität auf. Diese wird noch dadurch gesteigert, dass sowohl die Gehäuseseitenteile 34 als auch die Gegenlagerteile 56 als Druckgussteile ausgebildet und aus einem Metall, beispielsweise aus Aluminium oder einer Aluminiumlegierung, gefertigt sind.In this way, the brush rollers 16 and 18 are rotatably mounted on the housing side parts 34 and the abutment members 56, wherein the abutment members 56 are held in a manner described below to the housing side parts 34. As a result, the mounting of the brush rollers 16 and 18 has a high stability. This is further enhanced by the fact that both the housing side parts 34 and the abutment parts 56 are formed as die-cast parts and made of a metal, for example aluminum or an aluminum alloy.

Darüber hinaus wirkt sich die Steifheit des Bürstengehäuses 30, die durch die Steifheit des teilweise als Hohlkörper ausgebildeten Gehäusemittelteiles 32 hervorgerufen wird, förderlich auf die Stabilität der Lagerung der Bürstenwalzen 16 und 18 aus.In addition, the stiffness of the brush housing 30, which is caused by the stiffness of the partially formed as a hollow body middle part 32, conducive to the stability of the storage of the brush rollers 16 and 18.

Zur Halterung jedes Gegenlagerteiles 56 an einem Gehäuseseitenteil 34 umfasst die Reinigungsvorrichtung 14 eine erste Verriegelungseinrichtung 96 (Figuren 9 und 11) mit einem ersten Verriegelungsglied 98, das am Gehäuseseitenteil 34 angeordnet ist, sowie einem zweiten Verriegelungsglied 100, das am Gegenlagerteil 56 angeordnet ist.For holding each abutment part 56 on a housing side part 34, the cleaning device 14 comprises a first locking device 96 (FIG. Figures 9 and 11 ) with a first locking member 98, which is arranged on the housing side part 34, and a second locking member 100, which is arranged on the abutment member 56.

Das erste Verriegelungsglied 98 ist in den Figuren 12 und 13 perspektivisch dargestellt. Es ist in Form einer zylindrischen Hülse 102 ausgestaltet mit einem Boden 104, von dem eine Nocke 106 in axialer Richtung absteht. Mittig steht vom Boden 104 der Hülse 102 in axialer Richtung eine Hülse 108 mit einem zentralen Durchgang 110 ab. Von einem Rand 112 der Hülse 102 steht in radialer Richtung ein Vorsprung 114 ab. Der Rand 112 fasst einen zweigeteilten, diametral ausgerichteten Drehgriff 116 ein.The first locking member 98 is in the FIGS. 12 and 13 shown in perspective. It is in the form of a cylindrical sleeve 102 configured with a bottom 104, from which a cam 106 protrudes in the axial direction. Centered from the bottom 104 of the sleeve 102 in the axial direction of a sleeve 108 with a central passage 110 from. From an edge 112 of the sleeve 102 is in the radial direction, a projection 114 from. The rim 112 includes a two-part, diametrically-oriented rotary handle 116.

Zur Anordnung des ersten Verriegelungsgliedes 98 weist das Gehäuseseitenteil 34 eine erste Verriegelungsgliedaufnahme 118 auf (Figuren 5 und 6), die einen Hülsenabschnitt 120 umfasst und einen von dem Hülsenabschnitt 120 teilweise eingefassten Lagerzapfen 122. Die vom Boden 104 des ersten Verriegelungsgliedes 98 axial abstehende Hülse 108 kann in den Hülsenabschnitt 120 der ersten Verriegelungsgliedaufnahme 118 eintauchen, wobei der Lagerzapfen 122 im zentralen Durchgang 110 des ersten Verriegelungsgliedes 98 angeordnet wird. Dadurch ist das erste Verriegelungsglied 98 an der ersten Verriegelungsgliedaufnahme 118 gehalten und die Möglichkeit gegeben, das erste Verriegelungsglied 98 am Gehäuseseitenteil 34 um eine parallel zu den Drehachsen 58 und 60 verlaufende Drehachse 124 zu drehen (Figur 9). Dies kann auf benutzerfreundliche Weise durch Erfassen des Drehgriffs 116 erfolgen.For arranging the first locking member 98, the housing side part 34 has a first locking member receptacle 118 (FIG. FIGS. 5 and 6 The sleeve 108 axially projecting from the bottom 104 of the first locking member 98 can be inserted into the sleeve portion 120 of the first locking member receptacle 118, the pivot 122 being located in the central passage 110 of the first locking member receptacle 118 first locking member 98 is arranged. As a result, the first locking member 98 is held on the first locking member receptacle 118 and given the opportunity to rotate the first locking member 98 on the housing side part 34 about a parallel to the axes of rotation 58 and 60 extending axis of rotation 124 ( FIG. 9 ). This can be done in a user-friendly manner by detecting the rotary handle 116.

Das zweite Verriegelungsglied 100 der ersten Verriegelungseinrichtung 96 ist als ein vom Rand 84 des Gegenlagerteiles 56 abstehender Haken 126 ausgebildet.The second locking member 100 of the first locking device 96 is formed as a projecting from the edge 84 of the abutment member 56 hook 126.

Wird das Gegenlagerteil 56 am Gehäuseseitenteil 34 positioniert, wobei der Rand 84 an der Anlagefläche 88 anliegt, kann das Gegenlagerteil 56 mittels der ersten Verriegelungseinrichtung 96 am Gehäuseseitenteil 34 verriegelt werden. Hierzu ist die Verriegelungseinrichtung 96 von einer Lösestellung, in der das erste Verriegelungsglied 98 mit dem zweiten Verriegelungsglied 100 außer Eingriff steht, durch Drehen um die Drehachse 124 in eine Verriegelungsstellung überführbar, in der das erste Verriegelungsglied 98 mittels der Nocke 106 den Haken 126 untergreift und mit diesem verrastet (Figur 11). Auf diese Weise ist das Gegenlagerteil 56 am Gehäuseseitenteil 34 gehalten. Die Stellung des Gegenlagerteiles 56, bei der es am Gehäuseseitenteil 34 gehalten ist, wird als Betriebsstellung des Gegenlagerteiles 56 bezeichnet.If the abutment part 56 is positioned on the housing side part 34, wherein the edge 84 bears against the abutment surface 88, the abutment part 56 can be locked on the housing side part 34 by means of the first locking device 96. For this purpose, the locking device 96 from a release position in which the first locking member 98 with the second locking member 100 is disengaged by rotating about the rotation axis 124 in a locking position convertible, in which the first locking member 98 by means of the cam 106 engages under the hook 126 and locked with this ( FIG. 11 ). In this way, the abutment member 56 is held on the housing side part 34. The position of the abutment part 56, in which it is held on the housing side part 34, is referred to as the operating position of the abutment part 56.

Durch Drehen des ersten Verriegelungsgliedes 98 um die Drehachse 124 in der entgegengesetzten Richtung kann die erste Verriegelungseinrichtung 96 von der Verriegelungsstellung in die Lösestellung überführt werden, indem der bestehende Eingriff zwischen der Nocke 106 und dem Haken 126 aufgehoben wird. Dies gibt die Möglichkeit, das Gegenlagerteil 56 vom Gehäuseseitenteil 34 zu entfernen, es also in eine Entnahmestellung zu überführen.By rotating the first locking member 98 about the axis of rotation 124 in the opposite direction, the first locking device 96 can be transferred from the locking position to the release position by removing the existing engagement between the cam 106 and the hook 126. This makes it possible to remove the abutment part 56 from the housing side part 34, ie to transfer it to a removal position.

Nach Entfernen des Gegenlagerteiles 56 vom Gehäuseseitenteil 34 kann der Eingriff des Lagerdorns 94 in die jeweilige Bürstenwalze 16 oder 18 aufgehoben werden, so dass die Bürstenwalze 16 bzw. 18 dem Bürstenraum 54 entnommen werden kann. Dies ist beispielsweise bei Verschleiß der Bürstenwalzen 16 und 18 erforderlich. Es ist auch möglich, die Bürstenwalzen 16 und 18 gegen andersartige Bürstenwalzen auszutauschen, die in Bezug auf die zu reinigende Bodenfläche 24 besonders ausgebildet oder geeignet sind.After removal of the abutment member 56 from the housing side part 34, the engagement of the bearing mandrel 94 in the respective brush roller 16 or 18 can be canceled, so that the brush roller 16 and 18, the brush chamber 54 can be removed. This is required, for example, when the brush rollers 16 and 18 wear out. It is also possible to replace the brush rollers 16 and 18 with different types of brush rollers, which are particularly designed or suitable with respect to the bottom surface 24 to be cleaned.

Nach dem Austausch der Bürstenwalze kann das Gegenlagerteil 56 wieder von der Entnahmestellung in die Betriebsstellung überführt werden, indem es am Gehäuseseitenteil 34 angeordnet und mittels der ersten Verriegelungseinrichtung 96 wie vorstehend beschrieben verriegelt wird.After replacement of the brush roller, the abutment member 56 can be transferred again from the removal position to the operating position by being arranged on the housing side part 34 and locked by means of the first locking device 96 as described above.

Über die erste Verriegelungsgliedaufnahme 118 hinaus weist das Gehäuseseitenteil 34 eine zweite Verriegelungsgliedaufnahme 128 und eine dritte Verriegelungsgliedaufnahme 130 auf, die jeweils einen Lagerzapfen 122 sowie zum Hülsenabschnitt 120 gleichwirkende Hülsenabschnitte 120' und 120" umfassen. Dies gibt die Möglichkeit, je ein zu dem ersten Verriegelungsglied 98 identisch ausgebildetes Verriegelungsglied an der zweiten Verriegelungsgliedaufnahme 128 und der dritten Verriegelungsgliedaufnahme 130 anzuordnen, so dass es am Gehäuseseitenteil 34 um eine Drehachse 132 bzw. eine Drehachse 134 (Figur 9) drehbar gelagert ist. Mittels eines zum ersten Verriegelungsglied 98 identisch ausgebildeten Verriegelungsgliedes können damit auch weitere Bauteile der Reinigungsvorrichtung 14 am Gehäuseseitenteil 34 verriegelt werden, wie dies im Folgenden beschreiben wird.Beyond the first latch member receptacle 118, the housing side member 34 includes a second latch member receptacle 128 and a third latch member receptacle 130, each including a journal 122 and sleeve portions 120 'and 120 "that coact with the sleeve portion 120. This provides the ability to connect to the first latch member 98 identically formed locking member on the second locking member receptacle 128 and the third locking member receptacle 130 to be arranged so that it is on the housing side part 34 about an axis of rotation 132 and a rotational axis 134 (FIG. FIG. 9 ) is rotatably mounted. By means of a locking member designed identically to the first locking member 98, other components of the cleaning apparatus 14 can thus also be locked on the housing side part 34, as will be described below.

Wie in den Figuren 2 und 3 zu erkennen ist, weist die Reinigungsvorrichtung 14 ein erstes seitliches Abstreifglied 136 sowie ein zweites seitliches Abstreifglied 138 auf, die um vertikale Schwenkachsen 140 bzw. 142 am Gehäusemittelteil 32 schwenkbar gelagert sind. Das zweite Abstreifglied 138 ist symmetrisch zum ersten Abstreifglied 136 ausgebildet, so dass im Folgenden nur das erste Abstreifglied 136 näher erläutert wird.As in the FIGS. 2 and 3 can be seen, the cleaning device 14, a first lateral wiper member 136 and a second lateral wiper member 138 which are pivotally mounted about vertical pivot axes 140 and 142 on the housing middle part 32. The second wiper member 138 is formed symmetrically with respect to the first wiper member 136, so that in the following only the first wiper member 136 will be explained in more detail.

Das erste Abstreifglied 136 trägt an seiner Unterseite eine Abstreiflippe 144 aus einem elastischen Material, beispielsweise aus Gummi, mit der die schmutzige Flüssigkeit von der zu reinigenden Bodenfläche 24 abgestreift werden kann. Dies stellt sicher, dass die Schmutzflotte nicht über die seitliche Begrenzung der Reinigungsvorrichtung 14 hinaus gelangt und so von der Schmutzaufnahmevorrichtung 28 der Bodenreinigungsmaschine 10 zuverlässig aufgenommen werden kann.The first wiper member 136 carries on its underside a wiper lip 144 made of an elastic material, such as rubber, with which the dirty liquid can be stripped from the bottom surface 24 to be cleaned. This ensures that the dirty liquor does not reach beyond the lateral boundary of the cleaning device 14 and can thus be reliably picked up by the dirt holding device 28 of the floor cleaning machine 10.

Nahe seinem, der Schwenkachse 140 abgewandten Ende ist das erste Abstreifglied 136 mittels einer zweiten Verriegelungseinrichtung 146 der Reinigungsvorrichtung 14 mit dem Gehäuseseitenteil 34 verriegelbar. Die zweite Verriegelungseinrichtung 146 umfasst ein erstes Verriegelungsglied 148, das identisch zum ersten Verriegelungsglied 98 der ersten Verriegelungseinrichtung 96 ausgebildet und in der zweiten Verriegelungsgliedaufnahme 128 angeordnet ist. Das erste Verriegelungsglied 148 wirkt mit einem zweiten Verriegelungsglied 150 der zweiten Verriegelungseinrichtung 146 zur Verriegelung des ersten Abstreifgliedes 136 zusammen.Near its end remote from the pivot axis 140, the first wiper member 136 can be locked to the housing side member 34 by means of a second locking device 146 of the cleaning device 14. The second locking device 146 comprises a first locking member 148, which is identical to the first locking member 98 of the first locking device 96 and arranged in the second locking member receptacle 128. The first locking member 148 cooperates with a second locking member 150 of the second locking means 146 for locking the first wiper member 136.

Das zweite Verriegelungsglied 150 ist ausgebildet in Form eines vom ersten Abstreifglied 136 in Richtung des Bürstenraumes 54 abstehenden Bügels 152. Der radiale Vorsprung 114 des ersten Verriegelungsgliedes 148 kann mit dem Bügel 152 in Eingriff gebracht und mit diesem verrastet werden. Stehen der Vorsprung 114 und der Bügel 152 miteinander in Eingriff, wird dies als Verriegelungsstellung der zweiten Verriegelungseinrichtung 146 bezeichnet. Durch Drehen des ersten Verriegelungsgliedes 148 um die Drehachse 132 kann der Eingriff aufgehoben werden. Dies definiert die Lösestellung der zweiten Verriegelungseinrichtung 146, bei der das erste Abstreifglied 136 um die Schwenkachse 140 nach außen schwenkbar ist. Dies erlaubt es, das erste Abstreifglied 136 von einer Betriebsstellung, bei der es am Bürstengehäuse 30 anliegt (Figuren 2 und 3) und mittels der zweiten Verriegelungseinrichtung 146 verriegelt ist, in eine Wartungsstellung zu überführen, die dem Benutzer den Zugang zum Gegenlagerteil 56 ermöglicht. Dies gestattet dem Benutzer beispielsweise, die Bürstenwalzen 16 und 18 wie vorstehend beschrieben auszutauschen.The second locking member 150 is formed in the form of a protruding from the first wiper 136 in the direction of the brush space 54 bracket 152. The radial projection 114 of the first locking member 148 can be brought into engagement with the bracket 152 and locked with it. If the projection 114 and the bracket 152 engage with each other, this is referred to as the locking position of the second locking device 146. By turning the first locking member 148 about the rotation axis 132, the engagement can be canceled. This defines the release position of the second locking device 146, in which the first wiper member 136 is pivotable about the pivot axis 140 to the outside. This allows the first wiper member 136 from an operating position in which it rests against the brush housing 30 ( FIGS. 2 and 3 ) and locked by means of the second locking means 146, to transfer to a maintenance position, which allows the user access to the abutment member 56. This allows the user, for example, to exchange the brush rollers 16 and 18 as described above.

Durch umgekehrtes Verschwenken um die Schwenkachse 140 kann das erste Abstreifglied 136 von der Wartungsstellung in die Betriebsstellung geschwenkt werden, woraufhin die zweite Verriegelungseinrichtung 146 von der Lösestellung in die Verriegelungsstellung durch Drehen des ersten Verriegelungsgliedes 148 um die Drehachse 132 überführt werden kann, um das erste Abstreifglied 136 zu verriegeln.By reversing pivoting about the pivot axis 140, the first stripping member 136 can be pivoted from the service position to the operative position, whereupon the second latch 146 can be transferred from the release position to the lock position by rotating the first latch member 148 about the pivot 132 about the first stripping member 136 to lock.

Um das auf der gegenüberliegenden Seite des Bürstengehäuses 30 angeordnete zweite Abstreifglied 138 mit dem zugeordneten Gehäuseseitenteil 34 zu verriegeln, ist es erforderlich, das entsprechende erste Verriegelungsglied, welches identisch zum ersten Verriegelungsglied 98 der ersten Verriegelungseinrichtung 96 ausgebildet ist, in der dritten Verriegelungsgliedaufnahme 130 des zugeordneten Gehäuseseitenteils 34 anzuordnen, weil auch das zweite Abstreifglied 138 nahe seinem der Schwenkachse 142 abgewandten Ende mit dem Gehäuseseitenteil 34 verriegelt wird (nicht gezeigt). Dementsprechend ist dieses erste Verriegelungsglied zum Überführen von der Verriegelungsstellung in die Lösestellung und umgekehrt um die Drehachse 134 zu drehen.In order to lock the second wiper member 138 arranged on the opposite side of the brush housing 30 with the associated housing side member 34, it is necessary that the corresponding first locking member, which is identical to the first locking member 98 of the first locking device 96, in the third locking member receptacle 130 of the associated Housing side part 34 to arrange, because also the second stripping member 138 is locked near its end remote from the pivot axis 142 with the housing side part 34 (not shown). Accordingly, this first locking member for transferring from the locking position to the release position and vice versa to rotate about the axis of rotation 134.

Durch die Möglichkeit, in den Verriegelungsgliedaufnahmen 118, 128 und 130 jeweils identisch ausgebildete Verriegelungsglieder anordnen zu können, um die Gegenlagerteile 56 sowie das erste Abstreifglied 136 und das zweite Abstreifglied 138 verriegeln zu können, weist die erfindungsgemäße Reinigungsvorrichtung 14 eine sehr hohe Vielseitigkeit auf und ist kostengünstig herstellbar. Die Verwendung identisch ausgebildeter Verriegelungsglieder vereinfacht überdies die Handhabung der Reinigungsvorrichtung 14.Due to the possibility of being able to arrange in the locking member receptacles 118, 128 and 130 each identically formed locking members in order to lock the abutment members 56 and the first wiper member 136 and the second wiper 138, the cleaning device 14 according to the invention has a very high versatility and is inexpensive to produce. The use of identically formed locking members also simplifies the handling of the cleaning device 14.

Auf die in den Figuren 2 und 3 nicht zu sehenden Gehäuseseitenteile 34 sind auf ihren dem Bürstenraum 54 abgewandten Außenseiten Abdeckglieder aufgesetzt, von denen in den Figuren 2 und 3 nur ein Abdeckglied 154 gezeigt ist. Durch die Abdeckglieder 154 können die Gehäuseseitenteile 34 und insbesondere die Antriebseinrichtungen 62 vor Schmutz und Reinigungsflüssigkeit geschützt werden.On the in the FIGS. 2 and 3 Not to see housing side parts 34 are placed on their outer side facing away from the brush space 54 cover members, of which in the FIGS. 2 and 3 only one cover member 154 is shown. By the cover members 154, the housing side parts 34 and in particular the drive means 62 can be protected from dirt and cleaning liquid.

Die Abdeckglieder 154 weisen an ihrer dem jeweiligen Gehäuseseitenteil 34 zugewandten Seite eine Vielzahl von in der Zeichnung nicht zu sehenden nockenartigen Vorsprüngen auf. Diese können mit einer Mehrzahl von Ausnehmungen 156 verrasten, die am Rand 112 des ersten Verriegelungsgliedes 98 der ersten Verriegelungseinrichtung 96 und des ersten Verriegelungsgliedes 148 der zweiten Verriegelungseinrichtung 146 gebildet sind. Das Verriegelungsglied 98 und das Verriegelungsglied 148 verrasten dadurch sowohl in ihrer Verriegelungsstellung als auch in ihrer Lösestellung mit dem Abdeckglied 154 und nehmen daher in Bezug auf dieses gesicherte und definierte Positionen ein. Dies sichert die Halterung des Gegenlagerteiles 56 am Gehäuseseitenteil 34 und der Abstreifglieder 136 und 138 am Gehäuseseitenteil 34 zusätzlich, weil ein unbeabsichtigtes Drehen des Verriegelungsgliedes 98 und des Verriegelungsgliedes 148 vermieden werden kann.The cover members 154 have on their side facing the respective housing side part 34 a plurality of not visible in the drawing cam-like projections. These can engage with a plurality of recesses 156, which are formed on the edge 112 of the first locking member 98 of the first locking means 96 and the first locking member 148 of the second locking means 146. The locking member 98 and the locking member 148 thereby lock both in its locking position and in its release position with the cover member 154 and therefore assume with respect to this secured and defined positions. This secures the support of the abutment member 56 on the housing side part 34 and the wiper members 136 and 138 on the housing side part 34 in addition, because inadvertent rotation of the locking member 98 and the locking member 148 can be avoided.
