Description

Die Erfindung betrifft eine Bürste für ein selbstfahrendes Bodenbearbeitungsgerät, mit einem Bürstenkern an dem ein Bürstenarm angeordnet ist, wobei in dem Bürstenarm ein Reinigungselement angeordnet ist.The invention relates to a brush for a self-propelled soil cultivation device, with a brush core on which a brush arm is arranged, a cleaning element being arranged in the brush arm.

Aus dem Stand der Technik bekannt sind Bürsten für selbstfahrende Bodenbearbeitungsgeräte mit einem Bürstenkern an dem mehrere Bürstenarme inklusive eines Reinigungselementes angeordnet sind. Die Bürstenarme erstrecken sich dabei weitestgehend starr vom Bürstenkern in Richtung der zu reinigenden Bodenfläche. Lediglich die Reinigungselemente, welche an den Bürstenarmen angeordnet sind und welche in direkten Kontakt mit der zu reinigenden Bodenfläche stehen, sind aufgrund ihrer Flexibilität beweglich. Funktion der Bürstenarme ist es, die Flexibilität der Reinigungselemente zu begrenzen, um ein Verknoten der Reinigungselemente, beispielweise an hochflorigen Teppichen, zu verhindern.An den bekannten Bürsten sind maximal drei Bürstenarme angeordnet. Diese Begrenzung ist erforderlich um sicherzustellen, dass ein selbstfahrendes Bodenbearbeitungsgerät mit solchen Bürsten Hindernisse wie Kabel oder hochflorige Teppiche sicher überfahren kann. Problematisch hierbei ist allerdings, dass die bekannten Bürsten aufgrund der geringen Anzahl an Bürstenarmen keine ausreichende Reinigungsleistung aufweisen. In Folge werden Ecken- und Wandbereiche von einem selbstfahrenden Bodenbearbeitungsgerät mit den bekannten Bürsten nur unzureichend gereinigt.Brushes for self-propelled soil cultivation devices with a brush core on which several brush arms including a cleaning element are arranged are known from the prior art. The brush arms extend largely rigidly from the brush core in the direction of the floor surface to be cleaned. Only the cleaning elements, which are arranged on the brush arms and which are in direct contact with the floor surface to be cleaned, are movable due to their flexibility. The function of the brush arms is to limit the flexibility of the cleaning elements in order to prevent the cleaning elements from becoming knotted, for example on high-pile carpets. A maximum of three brush arms are arranged on the known brushes. This limitation is necessary to ensure that a self-propelled soil cultivation device with such brushes can safely drive over obstacles such as cables or deep-pile carpets. The problem here, however, is that the known brushes do not have sufficient cleaning performance due to the small number of brush arms. As a result, corner and wall areas are only insufficiently cleaned by a self-propelled soil cultivation device with the known brushes.

Aus den Druckschriften JP 2015 112424 A , JP 2015 091290 A und JP 2016 182300 A sind Bürsten für selbstfahrende Bodenbearbeitungsgeräte bekannt, welche einen Bürstenkern aufweisen an dem mehrere Bürstenarme inklusive eines Reinigungselementes angeordnet sind. Die Bürstenarme sind dabei so ausgeführt, dass eine vertikale Beweglichkeit des Bürstenarms in Bezug auf die zu bearbeitende Bodenfläche im Reinigungsbetrieb des selbstfahrenden Bodenbearbeitungsgerätes ermöglicht wird. Problematisch hierbei ist, dass die vertikale Beweglichkeit der bekannten Bürstearme nicht ausreichend ist, um Hindernisse wie Kabel, Türschwellen oder hochflorige Teppiche sicher überfahren zu können.From the pamphlets JP 2015 112424 A , JP 2015 091290 A and JP 2016 182300 A Brushes for self-propelled soil cultivation devices are known which have a brush core on which several brush arms including a cleaning element are arranged. The brush arms are designed in such a way that vertical mobility of the brush arm in relation to the floor surface to be treated is made possible during the cleaning operation of the self-propelled floor treatment device. The problem here is that the vertical mobility of the known brush arms is not sufficient to be able to safely drive over obstacles such as cables, door sills or high-pile carpets.

Der Erfindung stellt sich somit das Problem eine verbesserte Bürste für selbstfahrende Bodenbearbeitungsgeräte zur Verfügung zu stellen, welche insbesondere in Bezug auf die Reinigungsleistung und die Überfahreigenschaft verbesserte Resultate erzielt. Erfindungsgemäß wird dieses Problem durch eine Vorrichtung mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.The invention thus has the problem of making available an improved brush for self-propelled soil cultivation devices which achieves improved results, in particular with regard to the cleaning performance and the drive-over property. According to the invention, this problem is solved by a device having the features of claim 1. Advantageous refinements and developments of the invention emerge from the subclaims.

Erfindungsgemäß ist der Bürstenarm so ausgebildet, dass eine vertikale Beweglichkeit des Bürstenarms in Bezug auf die zu bearbeitende Bodenfläche im Reinigungsbetrieb des selbstfahrenden Bodenbearbeitungsgerätes ermöglicht wird. Die vertikale Beweglichkeit des Bürstenarms ermöglicht im Reinigungsbetrieb ein Vergrößern und Verkleinern des Abstandes zwischen dem Bürstenarm und der zu bearbeitenden Bodenflächen. Mit anderen Worten kann sich der Bürstenarm im Reinigungsbetrieb durch eine Vertikalbewegung von der zu bearbeitenden Bodenfläche entfernen oder annähern. Im Reinigungsbetrieb wird die Vertikalbewegung des Bürstenarms initiiert von Objekten, welche sich auf der zu bearbeitenden Bodenfläche befinden und in Kontakt mit der Bürste kommen. Überfährt das selbstfahrende Bodenbearbeitungsgerät mit der Bürste ein solches Objekt, überträgt sich ein Kraftmoment über das Reinigungselement auf den Bürstenarm. Infolge dieser Kraftübertragung wird der Bürstenarm vertikal ausgelenkt, sodass sich der vertikale Abstand zwischen dem Bürstenarm und der zu bearbeitenden Bodenfläche vergrößert. Sobald das auslenkende Objekt auf der Bodenfläche überfahren ist erfolgt eine entgegengesetzte Bewegung des Bürstenarms in seine Ausgangsposition. In der Folge verkleinert sich der Abstand zwischen dem Bürstenarm und der zu bearbeitenden Bodenfläche. Die vertikale Bewegung des Bürstenarms ist an dem Ende des Bürstenarms größer, an dem das Reinigungselement am Bürstenarm angeordnet ist. Jeder Bürstenarm welcher an einer erfindungsgemäßen Bürste angeordnet ist, ist unabhängig von den anderen Bürstenarmen an der Bürste beweglich.According to the invention, the brush arm is designed in such a way that vertical mobility of the brush arm in relation to the floor surface to be treated is made possible during the cleaning operation of the self-propelled floor treatment device. The vertical mobility of the brush arm enables the distance between the brush arm and the floor surfaces to be processed to be increased and decreased in the cleaning mode. In other words, during the cleaning operation, the brush arm can move away from or approach the floor surface to be processed by a vertical movement. In the cleaning mode, the vertical movement of the brush arm is initiated by objects which are located on the floor surface to be processed and which come into contact with the brush. If the self-propelled soil cultivation device runs over such an object with the brush, a moment of force is transmitted to the brush arm via the cleaning element. As a result of this power transmission, the brush arm is deflected vertically, so that the vertical distance between the brush arm and the floor surface to be processed increases. As soon as the deflecting object has been passed over on the floor surface, the brush arm moves in the opposite direction to its starting position. As a result, the distance between the brush arm and the floor surface to be processed is reduced. The vertical movement of the brush arm is greater at the end of the brush arm where the cleaning element is arranged on the brush arm. Each brush arm which is arranged on a brush according to the invention is movable independently of the other brush arms on the brush.

Die vertikale Beweglichkeit der Bürstenarme an der Bürste verbessern deren Überfahreigenschaften. Das heißt ein selbstfahrendes Bodenbearbeitungsgerät mit einer erfindungsgemäßen Bürste ist in der Lage Objekte, welche sich auf der zu bearbeitenden Bodenfläche befinden, störungsfrei zu überfahren. Darüber hinaus ermöglichen die verbesserten Überfahreigenschaften der Bürste die Anordnung zusätzlicher Bürstenarme an der Bürste. Auf diese Weise lässt sich die Reinigungsleistung der Bürste steigern ohne das Risiko eines Festfahrens des selbstfahrenden Bodenbearbeitungsgerätes zu erhöhen.The vertical mobility of the brush arms on the brush improve its drive-over properties. That is to say, a self-propelled soil cultivation device with a brush according to the invention is able to drive over objects which are located on the ground surface to be processed without interference. In addition, the improved drive-over properties of the brush enable additional brush arms to be arranged on the brush. In this way, the cleaning performance of the brush can be increased without increasing the risk of the self-propelled soil cultivation device getting stuck.

In einer Ausführungsform ist es bevorzugt, dass der Bürstenarm so ausgebildet ist, dass zusätzlich eine horizontale Beweglichkeit des Bürstenarms in Bezug auf die zu bearbeitende Bodenfläche im Reinigungsbetrieb des selbstfahrenden Bodenbearbeitungsgerätes ermöglicht wird. Mit anderen Worten können die Bürstenarme neben einer vertikalen Bewegung eine horizontale Bewegung ausführen. Die vertikale Beweglichkeit der Bürstenarme ist deutlich stärker ausgeprägt als deren horizontale Beweglichkeit. Im Reinigungsbetrieb der Bürste wird eine horizontale Bewegung eines Bürstenarms durch Objekte initiiert, welche sich auf der zu bearbeitenden Fläche befinden und in Kontakt mit der Bürste kommen. Infolge der Auslenkung eines Bürstenarmes durch ein Objekt können sich horizontale und vertikale Bewegungsanteile überlagern. Es kann aber auch zu isoliert vertikalen oder isoliert horizontalen Bewegungen eines Bürstenarms kommen. Die horizontale Bewegung des Bürstenarms ist an dem Ende des Bürstenarms größer, an dem das Reinigungselement am Bürstenarm angeordnet ist. Jeder Bürstenarm welcher an einer erfindungsgemäßen Bürste angeordnet ist, ist unabhängig von den anderen Bürstenarmen an der Bürste beweglich.In one embodiment, it is preferred that the brush arm is designed in such a way that, in addition, horizontal mobility of the brush arm in relation to the floor surface to be treated is made possible during the cleaning operation of the self-propelled floor treatment device. In other words, the brush arms can move horizontally in addition to a vertical movement. The vertical mobility of the brush arms is much more pronounced than their horizontal mobility. During the cleaning operation of the brush, a horizontal movement of a brush arm is initiated by objects which are located on the surface to be treated and which come into contact with the brush. As a result of the deflection of a brush arm by an object, horizontal and vertical movement components can overlap. However, isolated vertical or isolated horizontal movements of a brush arm can also occur. The horizontal movement of the brush arm is at the end of the Brush arm larger on which the cleaning element is arranged on the brush arm. Each brush arm which is arranged on a brush according to the invention is movable independently of the other brush arms on the brush.

Die horizontale Beweglichkeit der Bürstenarme verhindert ein Verkanten der Bürste im Reinigungsbetrieb. Zudem wird hierdurch die Reinigung von besonders verwinkelten Raumgeometrien durch das selbstfahrenden Bodenbearbeitungsgerät verbessert.The horizontal mobility of the brush arms prevents the brush from tilting during cleaning. In addition, the cleaning of particularly angled room geometries is improved by the self-propelled soil cultivation device.

Erfindungsgemäss weist der Bürstenarm mindestens eine Einkerbung auf. Die Einkerbungen bewirken eine partielle Reduzierung der Festigkeit der Bürstenarme. Mit anderen Worten wird die Flexibilität der Bürstenarme in eine Bewegungsrichtung erhöht. Die Einkerbungen sind dabei so im Bürstenarm angeordnet, dass sich in Folge der reduzierten Festigkeit die Beweglichkeit der Bürstenarme, insbesondere in vertikaler Richtung, verbessert. Die Einkerbungen ermöglichen eine verbesserte vertikale Beweglichkeit der Bürstenarme im Reinigungsbetrieb der Bürste.According to the invention, the brush arm has at least one notch. The notches cause a partial reduction in the strength of the brush arms. In other words, the flexibility of the brush arms is increased in one direction of movement. The notches are arranged in the brush arm in such a way that, as a result of the reduced strength, the mobility of the brush arms, in particular in the vertical direction, is improved. The notches allow an improved vertical mobility of the brush arms during the cleaning operation of the brush.

Weiterhin ist es bevorzugt, dass die Einkerbung auf der Seite des Bürstenarms angeordnet ist, welche im Reinigungsbetrieb von der zu bearbeitenden Bodenfläche abgewandt ist. Zudem ist es bevorzugt, dass die Einkerbung auf der Seite des Bürstenarms angeordnet ist, welche im Reinigungsbetrieb der zu bearbeitenden Bodenfläche zugewandt ist. In einer bevorzugten Ausführungsform sind dabei die Einkerbungen auf Ober- und Unterseite des Bürstenarmes versetzt zueinander angeordnet. Das heißt die Einkerbungen auf Ober- und Unterseite des Bürstenarmes sind nicht direkt übereinander angeordnet, sondern weisen einen Versatz zueinander auf.Furthermore, it is preferred that the notch is arranged on the side of the brush arm which faces away from the floor surface to be processed during the cleaning operation. In addition, it is preferred that the notch is arranged on the side of the brush arm which faces the floor surface to be processed during the cleaning operation. In a preferred embodiment, the notches on the top and bottom of the brush arm are offset from one another. This means that the notches on the top and bottom of the brush arm are not arranged directly one above the other, but are offset from one another.

Bevorzugt ist, dass die Einkerbungen auf dem Bürstenarm annähernd parallel zueinander angeordnet sind. In einer Ausführungsform weisen die Einkerbungen auf dem Bürstenarm unterschiedliche Längen auf.It is preferred that the notches on the brush arm are arranged approximately parallel to one another. In one embodiment, the notches on the brush arm have different lengths.

Bevorzugt ist, dass der Bürstenarm einen ersten Abschnitt aufweist, welcher am Bürstenkern angeordnet ist, und einen zweiten Abschnitt aufweist, welcher zur Aufnahme eines Reinigungselementes geeignet ist, wobei der erste Abschnitt einen geringeren Umfang als der zweite Abschnitt aufweist. Der Umfang des ersten Abschnitts des Bürstenarms reduziert sich durch einen Einschnitt, wobei der Einschnitt auf der Seite des Bürstenarms angeordnet ist, welcher entgegengesetzt zur Drehrichtung der Bürste im Reinigungsbetrieb angeordnet ist. Infolge des reduzierten Umfangs des ersten Abschnitts des Bürstenarms erhöht sich dessen Flexibilität in Bezug auf eine vertikale und horizontale Beweglichkeit. Somit resultiert die Beweglichkeit des Bürstenarms in erster Linie aus einer Beweglichkeit des ersten Abschnittes. Die Anordnung des Einschnittes auf der Seite des Bürstenarms welcher entgegengesetzt zur Drehrichtung der Bürste im Reinigungsbetrieb angeordnet ist, erhöht die horizontale Beweglichkeit des Bürstenarms entgegengesetzt zur Drehrichtung der Bürste. Diese horizontale Beweglichkeit der Bürstenarme verhindert ein Festdrehen der Bürste an Hindernissen, welche sich auf einer zu bearbeitenden Bodenfläche befinden.It is preferred that the brush arm has a first section which is arranged on the brush core and a second section which is suitable for receiving a cleaning element, the first section having a smaller circumference than the second section. The circumference of the first section of the brush arm is reduced by an incision, the incision being arranged on the side of the brush arm which is arranged opposite to the direction of rotation of the brush in the cleaning mode. As a result of the reduced circumference of the first section of the brush arm, its flexibility in terms of vertical and horizontal mobility increases. The mobility of the brush arm thus results primarily from the mobility of the first section. The arrangement of the incision on the side of the brush arm which is opposite to the direction of rotation of the brush in the cleaning mode increases the horizontal Mobility of the brush arm opposite to the direction of rotation of the brush. This horizontal mobility of the brush arms prevents the brush from turning tight on obstacles which are located on a floor surface to be worked.

Es ist bevorzugt, dass die Einkerbungen am ersten Abschnitt des Bürstenarms angeordnet sind. Somit sind die Einkerbungen auf dem Abschnitt des Bürstenarms angeordnet, welcher in Folge eines geringeren Umfangs eine erhöhte Flexibilität aufweist. Die Einkerbungen bewirken eine zusätzliche Steigerung der Flexibilität dieses ersten Abschnittes. In einer alternativen Ausführungsform ist denkbar, die Einkerbungen sowohl auf dem ersten und zweiten Abschnitt des Bürstenarms anzuordnen. Dies würde die Flexibilität des Bürstenarms zusätzlich steigern. In einer weiteren alternativen Ausführungsform ist es zudem denkbar, die Einkerbungen nur auf dem zweiten Abschnitt des Bürstenarms anzuordnen.It is preferred that the notches are arranged on the first section of the brush arm. The notches are thus arranged on the section of the brush arm which has increased flexibility as a result of a smaller circumference. The notches cause an additional increase in the flexibility of this first section. In an alternative embodiment it is conceivable to arrange the notches on both the first and second sections of the brush arm. This would additionally increase the flexibility of the brush arm. In a further alternative embodiment, it is also conceivable to arrange the notches only on the second section of the brush arm.

Zudem ist es bevorzugt, dass der Bürstenkern aus einem formstabilen Kunststoff besteht und der Bürstenarm aus einem elastischen Kunststoff besteht. Bevorzugt lässt sich hierbei der Bürstenkern aus einem thermoplastischen Material herstellen und der Bürstenarm aus einem elastomeren Material. Bevorzugt ist die Herstellung einer erfindungsgemäßen Bürste bestehend aus Bürstenkern und Bürstenarm im Zuge eines Zwei-Komponenten-Spritzgussverfahrens.In addition, it is preferred that the brush core consists of a dimensionally stable plastic and the brush arm consists of an elastic plastic. The brush core can preferably be produced from a thermoplastic material and the brush arm from an elastomeric material. The production of a brush according to the invention consisting of a brush core and a brush arm in the course of a two-component injection molding process is preferred.

Die Fertigung des Bürstenarms aus einem elastischen Kunststoff gewährleistet eine ausreichende Beweglichkeit des Bürstenarms sowohl in horizontale als auch vertikale Richtung. Die inhärente Flexibilität eines elastischen Kunststoffes stellt zudem sicher, dass sich der Bürstenarm nach einer Auslenkung durch ein Hindernis aus der zu bearbeitenden Bodenfläche selbstständig in seine Ausgangsposition zurückbewegt. Die Fertigung des Bürstenkerns aus einem formstabilen Kunststoff gewährleistet die erforderliche Grundstabilität der Bürste und eine verlustfreie Übertragung des Drehmoments auf die Bürstenarme.The manufacture of the brush arm from an elastic plastic ensures sufficient mobility of the brush arm in both the horizontal and vertical directions. The inherent flexibility of an elastic plastic also ensures that the brush arm automatically moves back into its starting position after being deflected by an obstacle from the floor surface to be processed. The manufacture of the brush core from a dimensionally stable plastic ensures the necessary basic stability of the brush and a loss-free transmission of the torque to the brush arms.

Es ist zusätzlich bevorzugt, dass das Reinigungselement ein Filamentbüschel ist. Ein Filamentbüschel bezeichnet dabei die Bündelung mehrerer Fasern zu einem Faserbündel. In alternativen Ausführungsformen ist aber auch die Anordnung anderer Reinigungselemente beispielsweise aus Textilelementen denkbar. Funktion der Filamentbüschel ist die möglichst vollständige Mobilisation von Staub- und Schmutzpartikel von der zu bearbeitenden Bodenfläche und deren Transport in Richtung des Saugmundes des selbstfahrenden Bodenbearbeitungsgerätes.It is additionally preferred that the cleaning element is a tuft of filaments. A filament tuft describes the bundling of several fibers into a fiber bundle. In alternative embodiments, however, the arrangement of other cleaning elements, for example made of textile elements, is also conceivable. The function of the filament tufts is to mobilize dust and dirt particles as completely as possible from the soil surface to be worked and to transport them in the direction of the suction mouth of the self-propelled soil cultivation device.

Figur 1 zeigt die perspektivische Darstellung eines selbstfahrenden Bodenbearbeitungsgerätes 12 mit zwei erfindungsgemäßen Bürsten 10. Das selbstfahrende Bodenbearbeitungsgerät 12 verfügt über ein Gehäuse 36 auf dessen Unterseite Räder 38 angeordnet sind, mit welchen das selbstfahrenden Bodenbearbeitungsgerät 12 autonom über zu bearbeitende Flächen verfährt. Auf der Unterseite des Gehäuse 36 (nicht dargestellt in Figur 1) ist ein Saugmund angeordnet, mit welchem das selbstfahrende Bodenbearbeitungsgerät 12 Staub- und Schmutzpartikel von der zu reinigenden Bodenfläche aufnimmt. An der Vorderseite des Gehäuses 36 des selbstfahrenden Bodenbearbeitungsgerätes 12 sind zwei erfindungsgemäße Bürsten 10 angeordnet. Die Bürsten 10 sind in Bezug auf die Hauptfahrrichtung des selbstfahrenden Bodenbearbeitungsgerätes 12 vor dessen Saugmund angeordnet. Figure 1 shows the perspective view of a self-propelled soil cultivation device 12 with two brushes 10 according to the invention. The self-propelled soil cultivation device 12 has a housing 36 on the underside of which wheels 38 are arranged, with which the self-propelled soil cultivation device 12 moves autonomously over surfaces to be worked. On the underside of the housing 36 (not shown in FIG Figure 1 ) a suction mouth is arranged with which the self-propelled soil cultivation device 12 picks up dust and dirt particles from the floor surface to be cleaned. Two brushes 10 according to the invention are arranged on the front of the housing 36 of the self-propelled soil cultivation device 12. The brushes 10 are arranged in relation to the main direction of travel of the self-propelled soil cultivation device 12 in front of its suction mouth.

Die Bürsten 10 überragen den Grundriss des Gehäuses 36 des selbstfahrenden Bodenbearbeitungsgerätes 12 und erfassen dadurch Staub- und Schmutzpartikel insbesondere in Rand- und Eckbereichen der zu reinigenden Bodenfläche. Die von den Bürsten 10 erfassten Staub- und Schmutzpartikel werden dabei in Richtung des Saugmunds unterhalb des Gehäuses 36 des selbstfahrenden Bodenbearbeitungsgerätes 12 gekehrt und anschließend eingesaugt. Dies ermöglich die Reinigung von Flächenbereichen, welche aufgrund der Flächengeometrie vom selbstfahrenden Bodenbearbeitungsgerät 12 nicht unmittelbar überfahren werden können.The brushes 10 protrude beyond the outline of the housing 36 of the self-propelled soil cultivation device 12 and thereby capture dust and dirt particles in particular in the edge and corner areas of the floor surface to be cleaned. The dust and dirt particles captured by the brushes 10 are swept in the direction of the suction mouth below the housing 36 of the self-propelled soil cultivation device 12 and then sucked in. This enables the cleaning of surface areas which, due to the surface geometry, cannot be driven over directly by the self-propelled soil cultivation device 12.

Figur 2 zeigt die perspektivische Darstellung einer Bürste 10. Mittig angeordnet ist der Bürstenkern 14 der Bürste 10, welcher Kopplungselemente 40 aufweist, mit dem die Bürste 10 mit einer Bürstenaufnahme eines selbstfahrenden Bodenbearbeitungsgerätes 12 verbindbar ist. Über die Kopplungselemente 40 des Bürstenkerns 14 wird ein Drehmoment von der Bürstenaufnahme des selbstfahrenden Bodenbearbeitungsgerätes 12 auf den Bürstenkern 14 übertragen. Die Drehrichtung 42 der Bürste 10 im Reinigungsbetrieb ist über einen Bewegungspfeil dargestellt. Vom Bürstenkern 14 erstrecken sich radial nach außen mehrere Bürstenarme 16. Dabei weisen diese Bürstenarme 16 einen ersten und einen zweiten Abschnitt 26, 28 auf. Dabei ist der erste Abschnitt 26 am Bürstenkern 14 angeordnet. Der erste Abschnitt 26 des Bürstenarms 16 weist einen geringeren Umfang als der zweite Abschnitt 28 des Bürstenarms 16 auf. Der geringere Umfang des ersten Abschnitts 26 resultiert aus einem Einschnitt 30 auf der Längsseite des Bürstenarms 16, welche entgegengesetzt zur Drehrichtung 42 der Bürste 10 angeordnet ist. Der Einschnitt 30 bewirkt eine erhöhte Flexibilität des Bürstenarms 16 im Bereich des ersten Abschnittes 26. Figure 2 14 shows the perspective illustration of a brush 10. The brush core 14 of the brush 10 is arranged in the center and has coupling elements 40 with which the brush 10 can be connected to a brush holder of a self-propelled soil cultivation device 12. A torque is transmitted from the brush holder of the self-propelled soil cultivation device 12 to the brush core 14 via the coupling elements 40 of the brush core 14. The direction of rotation 42 of the brush 10 in the cleaning mode is shown by a movement arrow. Several brush arms 16 extend radially outward from the brush core 14. These brush arms 16 have a first and a second section 26, 28. The first section 26 is arranged on the brush core 14. The first section 26 of the brush arm 16 has a smaller circumference than the second section 28 of the brush arm 16. The smaller circumference of the first section 26 results from an incision 30 on the longitudinal side of the brush arm 16, which is opposite to the Direction of rotation 42 of the brush 10 is arranged. The incision 30 brings about increased flexibility of the brush arm 16 in the area of the first section 26.

Auf der Oberseite des ersten Abschnittes 26 des Bürstenarmes 16 sind vier Einkerbungen 20 angeordnet. Die Oberseite 22 ist dabei die Seite des Bürstenarmes 16, welche im Reinigungsbetrieb von der zu bearbeitenden Fläche abgewandt ist. Die Einkerbungen 20 auf dem Bürstenarm 16 weisen unterschiedliche Längen auf, sind aber annähernd parallel zueinander angeordnet. Am Ende der zweiten Abschnitte 28 der Bürstenarme 16 sind in Aufnahmen 44 Filamentbüschel angeordnet. Diese Filamentbüschel setzen sich aus einzelnen Fasern zusammen und befinden sich im Reinigungsbetrieb im Eingriff mit dem zu bearbeitenden Bodenbelag. Die Filamentbüschel der Bürste 10 weisen dabei unterschiedliche Längen auf. Die Bürstenarme 16 der Bürste 10 weisen in Bezug auf ihre geometrische Ausprägung weitestgehend identische Abmessungen auf.Four notches 20 are arranged on the upper side of the first section 26 of the brush arm 16. The top 22 is the side of the brush arm 16 which faces away from the surface to be processed in the cleaning mode. The notches 20 on the brush arm 16 have different lengths, but are arranged approximately parallel to one another. At the end of the second sections 28 of the brush arms 16, filament tufts are arranged in receptacles 44. These tufts of filaments are made up of individual fibers and are in contact with the floor covering to be processed during the cleaning operation. The filament tufts of the brush 10 have different lengths. The brush arms 16 of the brush 10 have largely identical dimensions with regard to their geometrical characteristics.

Figur 3 zeigt die Seitenansicht einer Bürste 10. Am Bürstenkern 14 sind umlaufend sechs Bürstenarme 16 angeordnet, welche sich ausgehend vom Bürstenkern 14 nach außen erstrecken. In den Bürstenarmen 16 sind Filamentbüschel 34 angeordnet, wobei die Filamentbüschel 34 unterschiedliche Längen aufweisen. Drei Filamentbüschel 34 weisen eine erste Länge auf und drei Filamentbüschel 34 weisen eine zweite Länge auf, wobei die erste Länge deutlich kürzer als die zweite Länge ist. Die sechs Filamentbüschel 34 mit erster und zweiter Länge sind in alternierender Reihenfolge am Bürstenkern 14 angeordnet. Figure 3 6 shows the side view of a brush 10. Six brush arms 16 are arranged circumferentially on the brush core 14 and extend outward from the brush core 14. Filament tufts 34 are arranged in the brush arms 16, the filament tufts 34 having different lengths. Three filament tufts 34 have a first length and three filament tufts 34 have a second length, the first length being significantly shorter than the second length. The six filament tufts 34 with first and second lengths are arranged on the brush core 14 in an alternating order.

Figur 4 zeigt die perspektivische Darstellung eines Bürstenarms 16. Der erste Abschnitt 26 des Bürstenarms 16 ist dabei mit einem Ende am Bürstenkern 14 angeordnet. An dem gegenüberliegenden Ende des ersten Abschnitts 26 geht dieser in den zweiten Abschnitt 28 des Bürstenarms 16 über. Im Verlaufe dieses Überganges zwischen dem ersten und zweiten Abschnitt verdickt sich der Bürstenarm 16. Am freien Ende des zweiten Abschnitts 28 ist eine Aufnahme 44 für ein Filamentbüschel 34 angeordnet. Im ersten Abschnitt 26 des Bürstenarms 16 sind auf dessen Ober- und Unterseite Einkerbungen 20 angeordnet. Die Einkerbungen 20 auf Ober- und Unterseite 22, 24 sind dabei versetzt zueinander angeordnet und bewirken eine Steigerung der Flexibilität des Bürstenarms Figure 4 shows the perspective view of a brush arm 16. The first section 26 of the brush arm 16 is arranged with one end on the brush core 14. At the opposite end of the first section 26, this merges into the second section 28 of the brush arm 16. In the course of this transition between the first and second section, the brush arm 16 thickens. At the free end of the second section 28, a receptacle 44 for a filament tuft 34 is arranged. In the first section 26 of the brush arm 16, notches 20 are arranged on its top and bottom. The notches 20 on the top and bottom 22, 24 are arranged offset to one another and bring about an increase in the flexibility of the brush arm
