Beispielsweise zeigt die EP 1 763 597 eine Reinigungsbürste aus einem Grundkörper mit darin befestigten Reinigungsborsten. Weiter offenbart die DE 43 34 246 eine Bürste zur Reinigung von garnierten Walzen welche am Umfang angeordnete Borstenlelsten aufweist.
Ebenfalls bekannt aus dem Stand der Technik sind Reinigungswalzen aus einem Walzenkörper mit auf dem Walzenkörper spiralförmig aufgebrachten Gamiturstreifen. Die Graniturstreifen werden dabei aus vorher gefertigten Nadeltüchern ausgeschnitten. Derartige Nadeltücher bestehen aus Geweben oder Vliesen mit darin eingestochenen U-förmigen Drahthäkchen. Die Enden der Drahthäkchen bilden dabei die Borsten und können vielfältige, auf die vorgesehene Anwendung abgestimmte Dimensionen und Formen aufweisen.Various designs of cleaning rollers are known from the prior art. For example, the shows EP 1 763 597 a cleaning brush made of a basic body with cleaning bristles fastened in it. Next discloses the DE 43 34 246 a brush for cleaning garnished rolls which has circumferentially arranged bristle elements.
Also known from the prior art are cleaning rollers of a roller body with spirally applied on the roller body Gamiturstreifen. The granite strips are cut out of previously made needle cloths. Such needle cloths consist of woven or non-woven fabrics with U-shaped wire hooks pierced therein. The ends of the wire hooks form the bristles and can have varied, tailored to the intended application dimensions and shapes.

Alle aus dem Stand der Technik bekannten Reinigungsbürsten respektive Reinigungswalzen haben den Nachteil, dass sie nach einer verschleissbedingten Abnutzung komplett zu ersetzen oder aufwändig instand zu stellen sind.All known from the prior art cleaning brushes or cleaning rollers have the disadvantage that they are completely replace after a wear-related wear or consuming to repair.

Der Erfindung liegt die Aufgabe zugrunde, eine Reinigungsbürste zu schaffen, welche sich durch einen einfachen Aufbau auszeichnet und einen einfachen Ersatz der Reinigungselemente ermöglichtThe invention has for its object to provide a cleaning brush, which is characterized by a simple structure and allows easy replacement of the cleaning elements

Die Aufgabe wird gelöst durch die Merkmale Im kennzeichnenden Teil der unabhängigen Ansprüche.The object is solved by the features in the characterizing part of the independent claims.

Zur Lösung der Aufgabe wird eine Reinigungsbürste mit einer Welle und mit auf der Welle aufgeschobenen Reinigungselementen vorgeschlagen.
Die Reinigungselemente sind zur Befestigung auf einem zylinderförmigen Grundkörper, beispielsweise einer Welle, vorgesehen. Die Reinigungselemente sind als zylinderförmige Hohlelemente mit einer Längsachse ausgebildet und umfassen ein Skelett und ein auf dem Skelett aufgebrachtes Nadeltuch. Das Skelett ist mit dem Nadeltuch über eine Gummivergussmasse verbunden und eine innere der Längsachse zugewandte Oberfläche des Reinigungselementes ist durch das Skelett oder die Gummivergussmasse gebildet.To solve the problem, a cleaning brush is proposed with a shaft and with deferred on the shaft cleaning elements.
The cleaning elements are provided for attachment to a cylindrical base body, for example a shaft. The cleaning elements are designed as cylindrical hollow elements with a longitudinal axis and comprise a skeleton and a needle cloth applied to the skeleton. The skeleton is connected to the needle cloth via a rubber molding compound and an inner longitudinal surface of the cleaning element facing the longitudinal axis is formed by the skeleton or the rubber molding compound.

Das Skelett wird gebildet durch in bestimmten Abständen konzentrisch zur Längsachse angeordnete Stützringe, welche über einen oder mehrere in Richtung der Längsachse verlaufende Stege gehalten sind. Auf die Stützringe wird ein Nadeltuch aufgebracht. Anschliessend wird der Innenraum des durch das Nadeltuch gebildeten Zylinders mit einer Gummivergussmasse, beispielsweise synthetischem Kautschuk, ausgefüllt Dabei wird entsprechend einer gewünschten Form ein Innenraum von der Gummivergussmasse ausgenommen und ein zylinderförmiges Hohlelement gebildet. Das Nadeltuch wird auf diese Weise durch die Gummivergussmasse mit dem Skelett verbunden, wobei auch die Bereiche des Nadeltuches zwischen den Stützringen des Skeletts durch die Gummivergussmasse gestützt werden. Alternativ umfasst das Skelett eine innere Hülse, auf die sich die in Längsrichtung verlaufenden Stege abstützen.The skeleton is formed by at certain intervals concentric with the longitudinal axis arranged support rings, which are held over one or more extending in the direction of the longitudinal axis webs. A needle cloth is applied to the support rings. Subsequently, the interior of the cylinder formed by the needle cloth with a rubber molding compound, such as synthetic rubber, filled in this case is excluded according to a desired shape, an interior of the rubber molding compound and formed a cylindrical hollow member. The needle cloth is thus connected to the skeleton by the rubber molding compound, whereby also the areas of the needle cloth between the skeletal support rings are supported by the rubber molding compound. Alternatively, the skeleton comprises an inner sleeve on which the longitudinal webs are supported.

In einer weiteren Ausführungsform wird das Skelett durch eine konzentrisch zur Längsachse angeordnete Hülse gebildet. Dabei wird das Nadeltuch in eine zylindrische Form gebracht und in eine Vorrichtung eingelegt, welche das Nadeltuch von aussen stützt. Innerhalb des zylindrischen Nadeltuches wird das Skelett in Form einer Hülse angeordnet. Anschliessend wird der Raum zwischen dem Skelett respektive der Hülse und dem Nadeltuch mit einer Gummivergussmasse verfüllt. Durch die Gummivergussmasse wird das Nadeltuch mit der Hülse verbunden. Derartige Ausführungsformen eignen sich insbesondere bei nur schwacher Beanspruchung der Reinigungselemente im Betrieb aufgrund der Eigenschaften des die Hülse mit dem Nadeltuch verbindenden Gummivergusses.In a further embodiment, the skeleton is formed by a sleeve arranged concentrically to the longitudinal axis. In this case, the needle cloth is brought into a cylindrical shape and placed in a device which supports the needle cloth from the outside. Within the cylindrical needle cloth, the skeleton is arranged in the form of a sleeve. Subsequently, the space between the skeleton respectively the sleeve and the needle cloth is filled with a rubber molding compound. Through the rubber molding compound, the needle cloth is connected to the sleeve. Such embodiments are particularly suitable for only weak stress of the cleaning elements in operation due to the properties of the sleeve connecting the sleeve with the needle cloth rubber overflow.

Das Skelett kann dabei aus Metall oder Kunststoff gefertigt sein. Vorteilhafterweise wird das Skelett oder zumindest ein Skelettelement als ein Spritzgussteil aus Polyamid hergestellt.The skeleton can be made of metal or plastic. Advantageously, the skeleton or at least one skeleton element is produced as an injection-molded part made of polyamide.

In einer ersten Ausführungsform ist das Skelett an seinen Enden derart ausgebildet, dass die Enden der Skelette zweier benachbarter Reinigungselemente derart ineinandergreifen, dass sie drehfest gegeneinander gehalten sind. Dies kann beispielsweise durch die Ausbildung von ineinandergreifenden Zähnen oder durch eine entsprechende Ausbildung der Stege verwirklicht werden.In a first embodiment, the skeleton is formed at its ends such that the ends of the skeletons of two adjacent cleaning elements engage in such a way that they are rotationally held against each other. This can be achieved for example by the formation of interlocking teeth or by a corresponding design of the webs.

In einer zweiten Ausführungsform ist ein Kupplungsstück vorgesehen. Das Skelett zweier benachbarter Reinigungselemente ist an ihren Enden derart ausgebildet, dass die Enden zweier benachbarter Reinigungselemente mit dem dazwischen liegenden Kupplungsstück derart ineinandergreifen, dass die Reinigungselemente drehfest gegeneinander gehalten sind, wobei das Kupplungsstück in den Reinigungselementen aufgenommen wird. Das Kupplungsstück wird dabei zwischen zwei Reinigungselementen auf den Grundkörper aufgeschoben. Die Ausbildung der Enden der Reinigungselemente ist dabei derart gestaltet, dass das Kupplungsstück in das Skelett des Reinigungselementes eingreift, beispielsweise über eine Verzahnung oder Stifte und dabei nach dem Zusammenschieben zweier benachbarter Reinigungselemente zwischen den Reinigungselementen kein Spalt verbleibt. Das Kupplungsstück fügt sich in die Skelette zweier benachbarter Reinigungselemente passgenau ein und die drehfeste Halterung wird innerhalb der Reinigungselemente verwirklicht. Dadurch ergibt sich der Vorteil, dass das Skelett des Reinigungselementes keine über die Länge des aufgebrachten Nadeltuches hinausragenden Elemente aufweisen.In a second embodiment, a coupling piece is provided. The skeleton of two adjacent cleaning elements is formed at their ends such that the ends of two adjacent cleaning elements with the intermediate coupling piece engage in such a way that the cleaning elements are rotatably held against each other, wherein the coupling piece is received in the cleaning elements. The coupling piece is thereby pushed onto the base body between two cleaning elements. The formation of the ends of the cleaning elements is designed such that the coupling piece engages in the skeleton of the cleaning element, for example via a toothing or pins and thereby remains after the pushing together of two adjacent cleaning elements between the cleaning elements no gap. The coupling piece fits snugly into the skeletons of two adjacent cleaning elements and the non-rotatable holder is realized within the cleaning elements. This gives the advantage that the skeleton of the cleaning element have no over the length of the applied needle cloth protruding elements.

Auf dieselbe Weise werden die Reinigungselemente auf dem zylindrischen Grundkörper drehfest gehalten. Der zylindrische Grundkörper weist dazu mindestens an einem seiner Enden ein der Ausbildung des Endes des Reinigungselementes oder des Kupplungsstückes entsprechendes Gegenstück auf. Dadurch wird es ermöglicht mehrere Reinigungselemente auf einem einzigen Grundkörper drehfest zu halten, dabei den Grundkörper als eine langgestreckte Welle auszuführen und die Reinigungselemente selbst als standardisierte einfach herzustellende und kurze Hohlkörper zu fertigen. Die Reinigungselemente und, abhängig von der Ausführungsform, die zugehörigen Kupplungsstücke werden auf die Welle aufgeschoben und in ihrer Gesamtheit in Richtung der Längsachse in bekannter Weise verspannt, beispielsweise durch Schrauben, Muttern, Spannringe oder ähnliches.In the same way, the cleaning elements are held against rotation on the cylindrical body. The cylindrical base body has for this purpose at least at one of its ends to the formation of the end of the cleaning element or the coupling piece corresponding counterpart. This makes it possible to hold a plurality of cleaning elements rotatably on a single body, while doing the main body as an elongated shaft and to produce the cleaning elements themselves as standardized easy to produce and short hollow body. The cleaning elements and, depending on the embodiment, the associated coupling pieces are pushed onto the shaft and braced in their entirety in the direction of the longitudinal axis in a known manner, for example by screws, nuts, clamping rings or the like.

In einer weiteren Ausführungsform ist die drehfeste Halterung auf dem Grundkörper dadurch gewährleistet, dass die innere Oberfläche der Reinigungselemente Vertiefungen oder Erhöhungen aufweist, welche sich in Richtung der Längsachse erstrecken. Der Grundkörper weist die entsprechende Spiegelung der Erhöhungen oder Vertiefungen der Reinigungselemente auf, wodurch eine formschlüssige und damit drehfeste Verbindung zwischen den Reinigungselementen und dem Grundkörper gegeben ist. Dadurch dass sich die Vertiefungen oder Erhöhungen in Richtung der Längsachse erstrecken sind die Reinigungselemente auf dem Grundkörper verschiebbar. Es können mehrere Reinigungselemente hintereinander auf denselben Grundkörper aufgeschoben werden.In a further embodiment, the rotationally fixed mount on the base body is ensured by the fact that the inner surface of the cleaning elements has depressions or elevations which extend in the direction of the longitudinal axis. The main body has the corresponding reflection of the elevations or depressions of the cleaning elements, whereby a positive and thus rotationally fixed connection between the cleaning elements and the base body is given. Because the recesses or elevations extend in the direction of the longitudinal axis, the cleaning elements are displaceable on the base body. Several cleaning elements can be pushed one behind the other onto the same base body.

In einer bevorzugten Ausführung ist das Skelett mit einer inneren Hülse versehen, auf welcher die Stege angeordnet sind, wobei die Stege wiederum die aussenliegenden Stützringe halten. Dabei wird die innere dem Grundkörper zugewandte Oberfläche des Reinigungselementes durch die innere Oberfläche des Skelettes respektive der dem Skelett zugeordneten Hülse gebildet. Die Hülse ist in ihrer Form derart ausgebildet, dass eine formschlüssige Verbindung mit dem Grundkörper hergestellt werden kann. Dabei ist auch eine zumindest teilweise gleichmässige zylindrische Form der inneren Abmessungen der Hülse als ein Formschluss mit einer glatten Welle zu betrachten. Unter einer formschlüssigen Verbindung ist auch eine Ausführung zu verstehen, bei weicher in der Hülse voneinander beabstandete Rippen vorgesehen sind welche auf dem Grundkörper zu Auflage kommen. In dieser Ausführung wird der Zwischenraum welcher durch das Nadeltuch und die Hülse begrenzt wird mit einer Gummivergussmasse ausgefüllt.In a preferred embodiment, the skeleton is provided with an inner sleeve on which the webs are arranged, wherein the webs in turn hold the outer support rings. In this case, the inner surface of the cleaning element facing the main body is formed by the inner surface of the skeleton or the sleeve assigned to the skeleton. The sleeve is formed in its shape such that a positive connection with the base body can be produced. In this case, an at least partially uniform cylindrical shape of the inner dimensions of the sleeve is to be regarded as a positive connection with a smooth shaft. Under a positive connection is also an embodiment to be understood, are provided in the sleeve spaced-apart ribs which come to rest on the body. In this embodiment, the space which is bounded by the needle cloth and the sleeve is filled with a rubber molding compound.

Das Skelett eines Reinigungselements kann aus mehreren Bauteilen zusammengesetzt sein, wobei die Bauteile untereinander Steckverbindungen aufweisen. Dies ermöglicht eine Herstellung von Skelettelementen in einheitlichen Dimensionen. Diese Skelettelemente werden dann direkt oder mit Hilfe von Zwischenelementen zu einem Skelett eines Reinigungselements der benötigten Länge zusammengesetzt. Unter einem Zwischenelement ist ein Bauteil zu verstehen, welches sich dadurch auszeichnet, dass es nur zur Verbindung von zwei Skelettelementen zu einem Skelett eines Reinigungselementes dient. Das Zwischenelement selbst weist hingegen im Unterschied zu einem Skelett oder Skelettelement keinen Steg oder Stützring auf. Durch die Wahl verschieden langer Zwischenelemente können Skelette durch Zusammenfügen einzelner Skelettelemente mit verschieden dimensionierten Zwischenelementen für die Herstellung von Reinigungselementen in beliebiger Länge bereitgestellt werden.The skeleton of a cleaning element may be composed of several components, wherein the components have plug connections with each other. This makes it possible to produce skeleton elements in uniform dimensions. These skeleton elements are then assembled directly or with the aid of intermediate elements to form a skeleton of a cleaning element of the required length. Under an intermediate element is a component to understand, which is characterized in that it serves only for the connection of two skeleton elements to a skeleton of a cleaning element. In contrast to a skeleton or skeleton element, the intermediate element itself has no web or support ring. By choosing different length intermediate elements skeletons can be provided by joining individual skeleton elements with different sized intermediate elements for the production of cleaning elements in any length.

Das zur Anwendung kommende Nadeltuch ist als ein zur Anwendung in Reinigungsbürsten vorgesehenes übliches Gewebe oder Vlies mit darin eingestochen U-förmigen Drahthäkchen ausgebildet. Die Form der Drahthäkchen oder deren Länge ist an die Verwendung anzupassen und kann verschiedenartig ausgeführt sein. Die Verteilung der Drahthäkchen über den Umfang oder die Länge des Reinigungselementes kann gleichmässig oder auch nach einem bestimmten Muster ausgeführt sein. Die sogenannte Benadelung des Nadeltuches ist abhängig von der späteren Verwendung des entsprechenden Reinigungselementes. Das Aufbringen des Nadeltuches auf das Skelett erfolgt derart, dass das Nadeltuch auf die benötigte Grösse zugeschnitten und zu einem Zylinder geformt wird. Die nun aneinanderstossenden Enden des Nadeltuches können durch verkleben, vernähen oder verschweissen verbunden werden. Danach wird das Nadeltuch über die Stützringe des Skeletts gelegt. Anschliessend wird das Nadeltuch auf dem Skelett fixiert, dies kann beispielsweise mit Hilfe von Klebern erfolgen. Es ist auch denkbar, dass das Skelett mit dem Nadeltuch in eine entsprechende Form eingelegt wird welche das Nadeltuch umschliesst und dieses so gegenüber dem innenliegenden Skelett fixiert.The applied needle cloth is designed as a customary for use in cleaning brushes usual fabric or nonwoven with inserted therein U-shaped wire hook. The shape of the wire hooks or their length is to be adapted to the use and can be carried out in various ways. The distribution of the wire hooks over the circumference or the length of the cleaning element can be performed evenly or according to a specific pattern. The so-called Benadelung of the needle cloth is dependent on the subsequent use of the corresponding cleaning element. The application of the needle cloth to the skeleton takes place in such a way that the needle cloth is cut to the required size and shaped into a cylinder. The now abutting ends of the needle cloth can be connected by gluing, sewing or welding. After that it will be Needle cloth placed over the skeletal support rings. Subsequently, the needle cloth is fixed on the skeleton, this can be done for example by means of adhesives. It is also conceivable that the skeleton is inserted with the needle cloth in a corresponding shape which encloses the needle cloth and this fixed so against the inner skeleton.

Anschliessend wird in den Hohlraum des Skeletts die Gummivergussmasse eingebracht wodurch einerseits das Skelett mit dem Nadeltuch verbunden wird und andrerseits die stabile zylindrische Form des Reinigungselementes erreicht wird. Die Verwendung einer Gummivergussmasse hat den Vorteil, dass das Nadeltuch elastisch abgestützt wird und damit durch die grössere Bewegungsfreiheit der Drahthäkchen eine höhere Reinigungswirkung erzielt werden kann. Bei einem Weglassen der Gummivergussmasse hingegen würde sich eine zu grosse Nachgiebigkeit des Nadeltuches ergeben und einem zu reinigenden Gegenstand könnte zu wenig Druck entgegengebracht werden.Subsequently, the rubber molding compound is introduced into the cavity of the skeleton whereby on the one hand the skeleton is connected to the needle cloth and on the other hand, the stable cylindrical shape of the cleaning element is achieved. The use of a rubber molding compound has the advantage that the needle cloth is elastically supported and thus a greater cleaning effect can be achieved by the greater freedom of movement of the wire hook. On the other hand, omitting the rubber compound would result in too much yielding of the needle cloth and too little pressure could be placed on an object to be cleaned.

Die erfindungsgemässe Reinigungsbürste umfasst eine Welle und auf der Welle aufgeschobene Reinigungselemente nach einer der obigen Ausführungsformen. Je nach Bedürfnis können so durch die Variierung der zur Anwendung kommenden Reinigungselemente in deren Länge, Anzahl, Dimension und aufgebrachter Nadeltücher Reinigungsbürsten zusammengestellt werden. Die drehfeste Verbindung der Reinigungselemente untereinander sowie mit der Welle erfolgt dabei durch entsprechende Ausbildung der Reinigungselemente und der Welle oder durch die Verwendung von entsprechenden Kupplungsstücken.The inventive cleaning brush comprises a shaft and slid on the shaft cleaning elements according to one of the above embodiments. Depending on the need, cleaning brushes can be assembled by varying the cleaning elements used in their length, number, dimension and applied needle cloths. The non-rotatable connection of the cleaning elements with each other and with the shaft takes place by appropriate design of the cleaning elements and the shaft or by the use of appropriate coupling pieces.

Im Folgenden wird die Erfindung anhand einer beispielhaften Ausführungsform erklärt und durch Zeichnungen näher erläutert.

Figur 1 und Figur 2 zeigen in schematischer Darstellung eine erste Ausführung eines Reinigungselementes 1, wobei Figur 1 den Querschnitt und Figur 2 den Längsschnitt an der Stelle A-A nach Figur 1 darstellt. Die beiden Figuren werden In der Folge zusammen betrachtet. Das Reinigungselement 1 mit seiner Längsachse 4 ist auf einem zylindrischen Grundkörper 2 gehalten und umfasst ein Skelett 3 mit einem aussenliegenden Nadeltuch 5. Das Skelett 3 setzt sich zusammen aus konzentrisch zur Längsachse 4 angeordneten Stützringen 8, welche auf in Richtung der Längsachse 4 verlaufenden Stegen 9 gehalten sind. Die Stege 9 wiederum sind auf einer Hülse 10 angebracht. Die Hülse 10 ist zylinderförmig und hat eine dem Grundkörper 2 zugewandte Oberfläche 7. Über diese Oberfläche 7 stützt sich das Reinigungselement 1 auf dem Grundkörper 2 ab. Die Beschaffenheit der Oberfläche 7 kann glatt oder strukturiert ausgeführt sein. Über die konzentrisch angelegten Stützringe 8 ist ein Nadeltuch 5 aufgebracht. Das Nadeltuch 5 weist über die Oberfläche verteilte darin eingestochene Drahthäkchen 12 auf. Die Drahthäkchen 12 sind in den Figuren schematisch dargestellt und können verschiedene Grössen, Formen und Längen aufweisen. FIG. 1 and FIG. 2 show a schematic representation of a first embodiment of a cleaning element 1, wherein FIG. 1 the cross section and FIG. 2 the longitudinal section at the point AA after FIG. 1 represents. The two figures are considered together in the episode. The cleaning element 1 with its longitudinal axis 4 is held on a cylindrical base body 2 and comprises a skeleton 3 with an outer needle cloth 5. The skeleton 3 is composed of concentric to the longitudinal axis 4 arranged support rings 8, which extend in the direction of the longitudinal axis 4 webs. 9 are held. The webs 9 in turn are mounted on a sleeve 10. The sleeve 10 is cylindrical and has a surface facing the base body 2 7. About this surface 7, the cleaning element 1 is supported on the base body 2 from. The nature of the surface 7 may be smooth or structured. About the concentric support rings 8 a needle cloth 5 is applied. The needle cloth 5 has wire hooks 12 pierced therein distributed over the surface. The wire hooks 12 are shown schematically in the figures and may have different sizes, shapes and lengths.

Der Raum zwischen dem Nadeltuch 5 und der Hülse 10 des Skelets 3 wird mit einer Gummivergussmasse 6 aufgefüllt. Dadurch entsteht eine Verbindung zwischen dem Skelett 3 und dem Nadeltuch 5. Das Nadeltuch 5 erhält auf diese Weise eine stabile zylindrische Form und kann über das Skelett 3 auf den Grundkörper 2 aufgeschoben werden.The space between the needle cloth 5 and the sleeve 10 of the skeleton 3 is filled with a rubber molding compound 6. This creates a connection between the skeleton 3 and the needle cloth 5. The needle cloth 5 is replaced in this way a stable cylindrical shape and can be pushed over the skeleton 3 on the base body 2.

Die Ausdehnung des Reinigungselementes 1 in Richtung der Längsachse 4 entspricht nicht in allen Fällen der Länge des mit den Reinigungselementen 1 zu versehenden Grundkörpers 2. Das Skelett 3, in der gezeigten Ausführungsform die Hülse 10 des Skeletts 3, ist an seinen Enden mit Zähnen 11 ausgeformt. Werden nun zwei Reinigungselemente 1 auf den Grundkörper 2 aufgeschoben greifen die Zähne 11 ineinander und die beiden Reinigungselemente 1 sind drehfest miteinander gekoppelt. Die gleiche Verzahnung 11 kann an zumindest einem Ende des Grundkörpers 2 zu drehfesten Halterung der Reinigungselemente 1 auf dem Grundkörper 2 genutzt werden (nicht dargestellt).The expansion of the cleaning element 1 in the direction of the longitudinal axis 4 does not correspond in all cases to the length of the body 2 to be provided with the cleaning elements 1. The skeleton 3, in the illustrated embodiment the sleeve 10 of the skeleton 3, is formed with teeth 11 at its ends , If two cleaning elements 1 are now pushed onto the base body 2, the teeth 11 engage in one another and the two cleaning elements 1 are coupled to each other in a rotationally fixed manner. The same toothing 11 can be used on at least one end of the main body 2 for rotationally fixed mounting of the cleaning elements 1 on the base body 2 (not shown).

In Figur 3 ist eine weitere Ausführungsform eines Reinigungselementes 1 in einem Längsschnitt schematisch dargestellt. Das Reinigungselement 1 ist auf einen Grundkörper 2 aufgeschoben. Das Reinigungselement 1 umfasst in der gezeigten Ausführungsform ein Skelett 3, welches sich aus mehreren Bauteilen 14, 15 zusammensetzt. Es sind zwei identische Skelettelemente 14 dargestellt welche mit einem Zwischenelement 15 verbunden sind. Jedes der Skelettelemente 14 weist eine Hülse 10 und konzentrisch zur Längsachse 4 angeordnete Stützringe 8 auf welche jeweils von einem Steg 9 gehalten werden. Das Zwischenelement 15 dient nur der Kopplung der Skelettelemente 14 und weist keine Stützringe 8 oder Stege 9 auf. Das Zwischenelement 15 schafft eine drehfeste Kopplung der Skelettelemente 14 mit Hilfe einer an den Enden der Skelettelemente 14 vorgesehenen Verzahnung 11. Durch die Verwendung von verschiedenen Längen des Zwischenelementes 15 können mit standardisierten Skelettelementen 14 beliebige Längen der Reinigungselemente bereitgestellt werden. Ober das gesamte Skelett 3 respektive dessen Stützringe 8 ist ein Nadeltuch 5 mit darin eingestochenen Drahthäkchen 12 aufgebracht. Der Raum zwischen der Hülse 10 und dem Nadeltuch 5 ist mit einer Gummivergussmasse 6 verfüllt.In FIG. 3 a further embodiment of a cleaning element 1 is shown schematically in a longitudinal section. The cleaning element 1 is pushed onto a base body 2. The cleaning element 1 comprises in the embodiment shown a skeleton 3, which is composed of several components 14, 15. Two identical skeleton elements 14 are shown, which are connected to an intermediate element 15. Each of the skeleton elements 14 has a sleeve 10 and support rings 8 which are arranged concentrically to the longitudinal axis 4 and which are each held by a web 9. The intermediate element 15 serves only to couple the skeleton elements 14 and has no support rings 8 or webs 9. The intermediate element 15 provides a rotationally fixed coupling of the skeleton elements 14 with the aid of a toothing 11 provided at the ends of the skeleton elements 14. By using different lengths of the intermediate element 15, standardized lengths of the cleaning elements can be provided with standardized skeleton elements 14. Above the entire skeleton 3 respectively the support rings 8, a needle cloth 5 is applied with inserted into it wire hook 12. The space between the sleeve 10 and the needle cloth 5 is filled with a rubber molding compound 6.

Figur 4 zeigt eine weitere Ausführungsform eines Reinigungselementes 1 in schematischer Darstellung in einem Querschnitt. Das Reinigungselement 1 umfasst ein Skelett und ein über das Skelett aufgebrachtes Nadeltuch 5 mit darin eingestochenen Drahthäkchen 12. Das Skelett setzt sich zusammen aus konzentrisch angeordneten Stützringen 8 welche von Stegen 9 gehalten werden. Die das Skelett und das Nadeltuch 5 verbindende Gummivergussmasse 6 wird derart eingebracht, dass wiederum ein Hohlelement entsteht, welches jedoch eine innere Oberfläche aufweist, die eine auf einen Grundkörper 2 abgestimmte Struktur oder Form aufweist. Beispielhaft ist in Figur 4 die Ausbildung von zwei Erhöhungen 13 im Reinigungselement 1. Diese Erhöhungen 13 greifen im Verwendungszustand in entsprechende Vertiefungen des Grundkörpers 2 und ergeben auf diese Art eine formschlüssige und dadurch drehfeste Verbindung zwischen dem Reinigungselement 1 und einem Grundkörper 2. Der Grundkörper 2 kann beispielsweise als Vielkeilwelle ausgeführt sein. FIG. 4 shows a further embodiment of a cleaning element 1 in a schematic representation in a cross section. The cleaning element 1 comprises a skeleton and a needle cloth 5 applied over the skeleton with wire hooks 12 pierced therein. The skeleton is composed of concentrically arranged support rings 8 which are held by webs 9. The skeleton and the needle cloth 5 connecting rubber molding compound 6 is introduced in such a way that in turn a hollow element is formed, which, however, has an inner surface having a matched to a base body 2 structure or shape. Exemplary is in FIG. 4 These elevations 13 engage in the use state in corresponding recesses of the base body 2 and result in this way a positive and thus rotationally fixed connection between the cleaning element 1 and a base body 2. The main body 2 may for example be designed as splined shaft be.

Figur 5 zeigt in schematischer Darstellung den Aufbau einer Reinigungsbürste. Auf einer Welle 2 sind mehrere Reinigungselemente 1 gehalten. Dabei ist ein erstes Reinigungselement 1 auf die Welle 2 aufgeschoben und in einem Spannelement 18 gehalten. Das Spannelement 18 ist derart gestaltet, dass das Reinigungselement 1 drehfest gehalten ist. Vor dem Aufschieben eines zweiten Reinigungselementes 1 wird ein Kupplungsstück 16 auf die Welle 2 aufgebracht. Das Kupplungsstück 16 wird über eine im Reinigungselement 1 vorgesehene Verzahnung drehfest mit diesem verbunden. Anstelle einer Verzahnung sind auch andere Verbindungen wie beispielsweise Stifte denkbar, welche zu einer drehfesten Verbindung von Reinigungselement 1 und Kupplungsstück 16 führen. Ein zweites Reinigungselement 1 wird nun in Richtung der Längsachse 4 und In Pfeilrichtung 17 gegen das erste Reinigungselement 1 auf die Welle 2 geschoben. Durch eine entsprechende Gestaltung des Reinigungselementes 1 greift auch das zweite Reinigungselement 1 in das Kupplungsstück 16. Dies führt zu einer drehfesten Verbindung der beiden Reinigungselemente 1 über das eingefügte Kupplungsstück 16. Das Kupplungsstück 16 wird von den beiden Reinigungselementen 1 vollständig aufgenommen, sodass im fertig montierten Zustand die Reinigungselemente 1 ohne Zwischenraum aneinander anliegen. FIG. 5 shows a schematic representation of the structure of a cleaning brush. On a shaft 2 more cleaning elements 1 are held. In this case, a first cleaning element 1 is pushed onto the shaft 2 and held in a clamping element 18. The clamping element 18 is designed such that the cleaning element 1 is held against rotation. Before pushing on a second cleaning element 1, a coupling piece 16 is applied to the shaft 2. The coupling piece 16 is rotatably connected thereto via a toothing provided in the cleaning element 1. Instead of a toothing other connections such as pins are conceivable, which lead to a rotationally fixed connection of cleaning element 1 and coupling piece 16. A second cleaning element 1 is now pushed in the direction of the longitudinal axis 4 and in the direction of arrow 17 against the first cleaning element 1 on the shaft 2. By an appropriate design of the cleaning element 1, the second cleaning element 1 engages in the coupling piece 16. This leads to a rotationally fixed connection of the two cleaning elements 1 via the inserted coupling piece 16. The coupling piece 16 is completely absorbed by the two cleaning elements 1, so in the finished assembled Condition the cleaning elements 1 abut each other without a gap.
