Description

Technisches GebietTechnical area

Die Erfindung betrifft eine als Reinigungsbürste verwendete Staubbürste nach dem Oberbegriff des Anspruch 1.The invention relates to a dust brush used as a cleaning brush according to the preamble of claim 1.

Stand der TechnikState of the art

Eine Reinigungsbürste ist aus der CA 2 610 307 A1 bekannt. Diese als Schneereinigungsbürste verwendete Bürste besitzt an einem Stiel eine Kopf, vom dem aus sich Reinigungselemente nach außen erstrecken. Dabei ist die äußere Kontur der Reinigungselemente im Wesentlichen rund oder in Abschnitten abgeflacht. Der Nachteil dieser Bürste besteht darin, dass sie nicht verwendet werden kann, um in Ecken eines Raumes oder entlang des Übergangs von Wand zu Decke bzw. hinter Vorhangleisten zu reinigen. Dies liegt an der äußeren Kontur, die ein gezieltes Eingreifen in die Ecke nicht ermöglicht, ohne dass die benachbarten Reinigungselemente massiv verformt werden müsste. Gerade in Verbindung mit einem Stiel ist dies aber besonders nachteilig, da der Benutzer ohnehin schon aufgrund des Stiels wenig Gefühl und nur eine vergleichsweise geringe Kraft aufbringen kann.A cleaning brush is out of the CA 2 610 307 A1 known. This brush used as a snow cleaning brush has on a stem a head from which cleaning elements extend to the outside. In this case, the outer contour of the cleaning elements is substantially round or flattened in sections. The disadvantage of this brush is that it can not be used to clean in corners of a room or along the transition from wall to ceiling or behind curtain rails. This is due to the outer contour, which does not allow a targeted intervention in the corner, without the neighboring cleaning elements would have to be deformed massive. Especially in connection with a stem but this is particularly disadvantageous, since the user already can muster little feeling and only a relatively small force already due to the stem.

Reinigungsbürsten in weiteren Ausgestaltungen, wie beispielsweise Staubwedel, sind in einer Vielzahl von Haushalten vorhanden und seit langem bekannt. Ein Beispiel ist in der US 2006/02009929 A1 beschrieben. Die bekannten Staubwedel weisen einen Borstenhalter und Borsten auf, die an dem Borstenhalter befestigt sind. Dabei sind aus dem Stand der Technik im Wesentlichen u-förmig ausgebildete Borstenhalter bekannt, die einen Basisabschnitt und zwei Schenkel, die sich jeweils von dem Basisabschnitt erstrecken, aufweisen. Zusätzlich weist der Borstenhalter eine Koppelvorrichtung auf, die ein Koppeln der Reinigungsbürste mit beispielsweise einer Stabvorrichtung ermöglicht. Genauer gesagt wird die Stabvorrichtung mit einem Koppelelement der Koppelvorrichtung gekoppelt, wobei das Koppelelement an einem Halteelement angebracht ist. Das Halteelement ist mit beiden Schenkeln verbunden, wobei das Koppelelement zwischen den beiden Schenkeln am Halteelement vorgesehen ist.Cleaning brushes in other embodiments, such as feather dusters, are available in a variety of households and have long been known. An example is in the US 2006/02009929 A1 described. The known feather dusters have a bristle holder and bristles which are fastened to the bristle holder. In this case, from the prior art substantially U-shaped bristle holders are known, which have a base portion and two legs, each extending from the base portion having. In addition, the bristle holder on a coupling device, which allows coupling of the cleaning brush with, for example, a rod device. More specifically, the rod device is coupled to a coupling element of the coupling device, wherein the coupling element is attached to a holding element. The holding element is connected to both legs, wherein the coupling element is provided between the two legs on the holding element.

Ein Problem, dass sich bei den bekannten Staubwedeln stellt ist, dass ein Reinigungsvorgang von unterschiedlichen Wandecken, bei denen sich zwischen den Wandflächen unterschiedliche Wandflächenwinkel ausbilden, schwierig ist. So kann bei Wandecken, bei denen sich zwischen den beiden Wandflächen ein 135° Wandflächenwinkel, wie beispielsweise bei einer abgehängten Decke in einem Speicher, oder ein 90° Wandflächenwinkel ausbildet, der in diesen Wandecken angesammelte Schmutz nicht einfach entfernt werden. Dies resultiert daher, dass die Reinigungsbürste zum Reinigen der Wandecke in eine Position gebracht wird, in der die an dem Basisabschnitt und/ oder die an einem der beiden Schenkeln vorgesehenen Borsten die jeweiligen die Wandecke begrenzenden Wandflächen berühren. Jedoch können in dieser Position die Borsten nicht in den jeweiligen Wandeckbereich derart eindringen, dass der dort vorhandene Schmutz entfernt werden kann.A problem that arises in the known dust dusters is that a cleaning process of different wall corners, where different wall surface angles form between the wall surfaces, is difficult. Thus, in wall corners in which a 135 ° wall surface angle forms between the two wall surfaces, such as in a suspended ceiling in a storage, or a 90 ° wall surface angle, the dirt accumulated in these wall corners can not be easily removed. This results from placing the cleaning brush for cleaning the wall corner in a position in which the bristles provided on the base section and / or the bristles provided on one of the two legs touch the respective wall surfaces bounding the wall corner. However, in this position, the bristles can not penetrate into the respective wall corner area in such a way that the dirt present there can be removed.

Um den in den Wandecken angesammelten Schmutz zu entfernen, muss auf den Staubwedel eine in Richtung der zu reinigenden Wandecke gerichtete Kraft ausgeübt werden. Die Kraft bewirkt, dass zumindest ein Teil der die Wandflächen bereits berührenden Borsten umknicken und somit ein Eindringen der beispielsweise mit dem Basisabschnitt verbundenen Borsten in den Wandeckbereich ermöglichen, um den sich dort befindlichen Schmutz zu entfernen. Ein derartiges Umknicken der Borsten kann im Extremfall zu einer Beschädigung der Borsten und somit zu einer Verringerung der Reinigungseffektivität des Staubwedels führen.In order to remove the dirt accumulated in the wall corners, a force directed in the direction of the wall corner to be cleaned must be exerted on the duster. The force causes at least a portion of the bristles already touching the wall surfaces to bend over and thus allow penetration of the bristles connected, for example, to the base section into the wall corner area in order to remove the dirt located there. Such bending over of the bristles can in extreme cases lead to damage of the bristles and thus to a reduction in the cleaning efficiency of the duster.

Aus der GB 2 417 415 A1 ist schließlich eine Bürste bekannt, die zwar eine spitze Bürstfläche aufweist, deren Borsten aber an einer durchgehenden Fläche vorgesehen sind, so dass diese Bürste eher die Form eines klassischen Besens aufweist. Mit einer solchen Bürste kann nicht hinter Hindernissen, z.B. einer Vorhangstange gearbeitet werden.From the GB 2 417 415 A1 Finally, a brush is known, although having a pointed brush surface, but the bristles are provided on a continuous surface, so that this brush is more in the shape of a classic broom. With such a brush can not be worked behind obstacles, such as a curtain rod.

Gleiches gilt für Bürsten, die aus der US 2008/295779 A1 , der US 2 279 209 und der US 1 617 329 bekannt sind.The same applies to brushes from the US 2008/295779 A1 , of the US 2,279,209 and the US Pat. No. 1,617,329 are known.

Darstellung der ErfindungPresentation of the invention

Es ist die Aufgabe der vorliegenden Erfindung, eine Staubbürste bereitzustellen, die auch in Ecken und längs von Kanten das Reinigen erleichtert.It is the object of the present invention to provide a dust brush which also facilitates cleaning in corners and along edges.

Insbesondere soll die neue Staubbürste den in Wandecken vorhandenen Schmutz ohne eine Kraftausübung und damit ohne Umknicken der Borsten entfernen können. Gerade bei Kunststoffborsten würde ansonsten die Gefahr bestehen, dass entweder die Borsten plastisch und damit irreversibel verformt würden oder durch zu hohen Druck der zu reinigende Untergrund beschädigt würde.In particular, the new dust brush should be able to remove the dirt present in wall corners without a force and thus without kinking the bristles. Especially in the case of plastic bristles, there would otherwise be the risk that either the bristles would be deformed plastically and thus irreversibly or that the surface to be cleaned would be damaged by excessive pressure.

Eine weitere Aufgabe der Erfindung besteht darin, dass die Reinigungsbürste für unterschiedliche Wandecken, d.h. für Wandecken, die einen unterschiedlichen Wandflächenwinkel zwischen den beiden Wandflächen ausbilden, verwendet werden kann, ohne dass eine Kraft auf die Reinigungsbürste ausgeübt werden muss.Another object of the invention is that the cleaning brush for different wall corners, i. for wall corners that form a different wall surface angle between the two wall surfaces, can be used without a force on the cleaning brush must be exercised.

Diese Aufgabe wird erfindungsgemäß durch eine Reinigungsbürste nach Anspruch 1 gelöst.This object is achieved by a cleaning brush according to claim 1.

Die Erfindung hat den Vorteil, dass bei einem Reinigungsvorgang von Wandecken keine Borsten umknicken, wodurch die Reinigungseffektivität der Reinigungsbürste nicht verringert wird. Zusätzlich können Wandecken, die einen unterschiedlichen Wandflächenwinkel zwischen den beiden Wandflächen aufweisen, durch entsprechendes Positionieren der Reinigungsbürste einfach gereinigt werden, ohne dass die Borsten umknicken. Diese Vorteile ergeben sich insbesondere durch ein Vorsehen eines ersten Winkels α, der sich zwischen einer ersten Teilfläche und einer dritten Teilfläche ausbildet, und eines zweiten Winkels β, der sich zwischen einer zweiten Teilfläche und einer dritten Teilfläche ausbildet, wobei der erste Winkel a einen anderen Wert aufweist als der zweite Winkel β.The invention has the advantage that in a cleaning process of wall corners do not buckle bristles, whereby the cleaning efficiency of the cleaning brush is not reduced. In addition, wall corners, which have a different wall surface angle between the two wall surfaces, can be easily cleaned by appropriate positioning of the cleaning brush, without the bristles kinking. These advantages result in particular by providing a first angle α, which forms between a first partial area and a third partial area, and a second angle β, which forms between a second partial area and a third partial area, the first angle a being different Has value as the second angle β.

Wesentlich für die Erfindung sind die beschriebenen Winkelverhältnisse. Die Winkel können dabei an die Geometrie der zu reinigen Fläche angepasst sein, wobei ein Universalgerät üblicherweise bevorzugt sein wird. Auch können die Winkel gleichsinnig oder gegensinnig verlaufen, der Winkel β also die Krümmung des Winkel α teilweise, vollständig oder sogar überkompensieren,Essential to the invention are the angle ratios described. The angles can be adapted to the geometry of the surface to be cleaned, with a universal device will usually be preferred. The angles can also run in the same direction or in opposite directions, ie the angle β can partially, completely or even overcompensate for the curvature of the angle α.

Die die Bürstfläche definierenden ersten, zweiten und dritten Teilflächen werden durch ein Ende der an einem Borstenhalter der Reinigungsbürste vorgesehen Borsten definiert. Durch die Wahl des Werts des ersten und zweiten Winkels ist es möglich, dass das Reinigungsbürste bei einer Reinigung einer Wandecke jeweils in eine entsprechende Position gebracht werden kann, in der die Borsten in den Wandeckbereich eindringen können, ohne dass ein Umknicken der Borsten bewirkender Kraftaufwand benötigt wird.The first, second and third partial surfaces defining the brushing surface are defined by one end of the bristles provided on a bristle holder of the cleaning brush. By choosing the value of the first and second angle, it is possible that the cleaning brush can be brought in a cleaning of a wall corner in each case in a corresponding position in which the bristles can penetrate into the wall corner area, without a buckling of the bristles causing force required becomes.

Eine weitere vorteilhafte Ausgestaltung der Erfindung besteht darin, dass an einem Schenkel eine Koppelvorrichtung zum Koppeln mit einer Stabvorrichtung vorgesehen ist, wobei die Koppelvorrichtung versetzt zu dem Schenkel angeordnet ist. Durch ein derartiges Anordnen der Koppelvorrichtung kann das Reinigungsbürste zum Entfernen von Schmutz aus schwer zugänglichen Wandecken, wie beispielsweise hinter einem Radiator, benutzt werden.A further advantageous embodiment of the invention is that a coupling device for coupling with a rod device is provided on a leg, wherein the coupling device is arranged offset to the leg. By arranging the coupling device, the cleaning brush can be used to remove dirt from hard-to-reach wall corners, such as behind a radiator.

Ferner besteht eine vorteilhafte Ausgestaltung der Erfindung darin, dass sich die Borstenlänge der am Borstenhalter angebrachten Borsten voneinander unterscheidet. So kann beispielsweise durch eine längere Ausbildung zumindest eines Teils der Borstenlänge der an einem Borstenhalter angebrachten Borsten sichergestellt werden, dass diese verlängerten Borsten in den betreffenden Wandeckbereich eindringen. Dadurch kann erreicht werden, dass die Reinigungsbürste auch bei Wandecken eingesetzt wird, bei denen der zwischen den Wandflächen ausgebildete Wandflächenwinkel einen kleinen Wert, wie beispielsweise 45°, besitzt. Im Ergebnis kann auch bei kleinen Wandflächenwinkeln zwischen den Wandflächen ein sich im Wandbereich befindlicher Schmutz entfernt werden, ohne das die an dem Borstenhalter angebrachten Borsten umknicken. Folglich erhöht sich die Reinigungseffektivität der Reinigungsbürste.Furthermore, an advantageous embodiment of the invention is that the bristle length of the bristles attached to the bristle holder is different from each other. Thus, for example, by prolonged formation of at least part of the bristle length of the bristles attached to a bristle holder, it can be ensured that these elongated bristles penetrate into the respective wall corner region. It can thereby be achieved that the cleaning brush is also used in wall corners, in which the wall surface angle formed between the wall surfaces has a small value, such as 45 °. As a result, even in the case of small wall surface angles between the wall surfaces, dirt located in the wall region can be removed without the bristles attached to the bristle holder being bent over. Consequently, the cleaning efficiency of the cleaning brush increases.

Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels anhand der Zeichnung.Further features of the invention will become apparent from the dependent claims and the following description of a preferred embodiment with reference to the drawing.

Zusammen bilden die Borsten 1 eine schmale, längliche Bürste mit einer Bürstfläche, die die drei zueinander abgewinkelten Teilflächen T1, T2 und T3 aufweist.The attached to the bristle holder 2 bristles 1 are composed of three groups 11 ', 11 "and 11'" together. Thus, the bristles 11 'attached to the first leg 10 form a first group and the bristles 11 "attached to the second leg 20 form a second group, and the bristles 11'" attached to the connecting portion 4 form a third group, with part of these bristles 1 abutting the first leg 10 and another part is attached to the second leg 20. The bristles 11 'of the first group and the bristles 11 "of the second group are each disposed adjacent to the bristles 11'" of the third group. Together, the bristles 1 form a narrow, elongate brush with a brush surface, which has the three mutually angled partial surfaces T1, T2 and T3.

In der in Figur 1 dargestellten Ausführungsform ist der zweite Schenkel 20 länger ausgebildet als der erste Schenkel 10. Es sind auch noch Ausführungsformen denkbar, in denen der erste Schenkel 10 genauso lang beziehungsweise länger ausgebildet ist als der zweite Schenkel 20. Der zwischen einer ersten Mittellinie 12 des ersten Schenkels 10 und einer zweiten Mittellinie 22 des zweiten Schenkels 20 ausgebildete Mittellinienwinkel ψ beträgt hier 45°.In the in FIG. 1 Embodiment shown, the second leg 20 is formed longer than the first leg 10. There are also embodiments conceivable in which the first leg 10 is formed as long or longer than the second leg 20. The between a first center line 12 of the first leg 10th and a second Center line 22 of the second leg 20 formed center line angle ψ is here 45 °.

Es sind auch noch Ausführungsformen vorstellbar, bei denen sich ein anderer Mittellinienwinkel ψ zwischen der ersten und zweiten Mittellinie 12, 22 ausbildet. Der Mittellinienwinkel ψ hängt vom Einsatzbereich des Staubwedels ab. Genauer gesagt hängt der Mittellinienwinkel ψ von dem sich zwischen den Wandflächen vorhandenen Wandflächenwinkel ab.Embodiments are also conceivable in which a different center line angle ψ between the first and second center lines 12, 22 is formed. The center line angle ψ depends on the area of use of the duster. More specifically, the centerline angle ψ depends on the wall surface angle existing between the wall surfaces.

Die Koppelvorrichtung 30 ist mit dem zweiten Schenkel 20 des Borstenhalters 2 verbunden und versetzt zu diesem angeordnet. Genauer gesagt ist die Koppelvorrichtung 30 in Richtung zum ersten Schenkel 10 versetzt vom zweiten Schenkel 20 angeordnet. Ferner erstreckt sich die Koppelvorrichtung 30 von dem Verbindungsabschnitt 4 weg und weist an ihrem von dem zweiten Schenkel 20 entfernten Ende ein Koppelelement 31 auf. Mittels des Koppelelements 31 wird der Staubwedel mit beispielsweise einer in Figur 1 nicht gezeigten Stabvorrichtung verbunden. Bei dem Koppelelement 31 kann es sich beispielsweise um einen Teil einer Steckverbindung handeln.The coupling device 30 is connected to the second leg 20 of the bristle holder 2 and arranged offset to this. More specifically, the coupling device 30 is arranged offset from the second leg 20 in the direction of the first leg 10. Furthermore, the coupling device 30 extends away from the connecting portion 4 and has a coupling element 31 at its end remote from the second leg 20. By means of the coupling element 31 of the duster with, for example, a in FIG. 1 Not shown rod device connected. The coupling element 31 may be, for example, a part of a plug connection.

Die an dem ersten und zweiten Schenkel 10, 20 angebrachten Borsten weisen eine unterschiedliche Länge auf. So sind zumindest ein Teil der am zweiten Schenkel 20 befestigten Borsten 11", 11'" der zweiten und/ oder dritten Gruppe länger ausgebildet als die am ersten Schenkel 10 befestigten Borsten 11' der ersten Gruppe und/oder Borsten dritten Gruppe 11'". Die Borstenlänge weist vorzugsweise einen Wert zwischen 5 bis 9 cm auf. Es sind auch andere Ausführungsformen vorstellbar, in denen zumindest ein Teil der am ersten Schenkel 10 befestigten Borsten 11', 11'" der ersten und/oder dritten Gruppe länger ausgebildet ist als die am zweiten Schenkel 20 befestigten Borsten 11" der zweiten und/oder Borsten 11'" der dritten Gruppe. Ferner sind auch andere Variationen bezüglich der Borstenlänge der an dem ersten und zweiten Schenkel 10, 20 angebrachten Borsten 11, 21 denkbar.The bristles attached to the first and second legs 10, 20 have a different length. Thus, at least some of the bristles 11 ", 11 '" of the second and / or third group fastened to the second leg 20 are made longer than the bristles 11' of the first group and / or bristles third group 11 '"fastened to the first leg 10. The bristle length preferably has a value between 5 and 9 cm, but other embodiments are conceivable in which at least some of the bristles 11 ', 11' "of the first and / or third group fastened to the first leg 10 are made longer than the bristles attached to the second leg 20 bristles 11 "of the second and / or bristles 11 '" of the third group. Furthermore, other variations in the bristle length of the attached to the first and second legs 10, 20 bristles 11, 21 are conceivable.

Das mit dem ersten und zweiten Schenkel 10, 20 nicht verbundene Ende der Borsten 1 bildet unterschiedliche Teilflächen T1, T2, T3 aus. So bilden die am ersten Schenkel 10 angebrachten Borsten 11 der ersten Gruppe eine erste Teilfläche T1 und die am zweiten Schenkel 10 angebrachten Borsten 12 der zweiten Gruppe eine von der ersten Teilfläche T1 verschiedene zweite Teilfläche T2 aus. Eine von der ersten und zweiten Teilfläche T1, T2 verschiedene dritte Teilfläche T3 wird durch die Borsten der dritten Gruppe gebildet. Genauer gesagt bilden die am Verbindungsabschnitt 4 angebrachten und Borsten 11, 21 der dritten Gruppe die dritte Teilfläche T3 aus. Die erste, zweite und dritte Teilfläche T1, T2, T3 werden in Fig. 1 mittels gestrichelter Linien dargestellt. Dabei handelt es sich bei diesen Teilflächen T1, T2, T3 um nur gedachte Teilflächen, die zur Erleichterung des Verständnisses der Erfindung beitragen sollen.The not connected to the first and second legs 10, 20 end of the bristles 1 forms different partial surfaces T1, T2, T3. Thus, the bristles 11 attached to the first leg 10 form the first group a first partial area T1 and the bristles 12 of the second group attached to the second leg 10 have a second partial area T2 that is different from the first partial area T1. A third partial area T3, which is different from the first and second partial areas T1, T2, is formed by the bristles of the third group. More specifically, the bristles 11, 21 of the third group attached to the connecting portion 4 form the third sub-area T3. The first, second and third partial area T1, T2, T3 are in Fig. 1 represented by dashed lines. These partial areas T1, T2, T3 are only imaginary partial areas which are intended to facilitate the understanding of the invention.

Die Borsten 11', 11", 11'" der ersten, zweiten und dritten Gruppe T1, T2, T3 sind an dem ersten und zweiten Schenkel 10, 20 derart angebracht, und die Borstenlänge der einzelnen Borsten 1 wird derart gewählt, dass ein sich zwischen der ersten und dritten Teilfläche T1, T3 ausgebildeter erster Winkel α einen anderen Wert aufweist als ein sich zwischen der zweiten und dritten Teilfläche T2, T3 ausgebildeter zweiter Winkel β. Der Wert des ersten und zweiten Winkel a, b wird dabei derart gewählt, dass er ungefähr dem Wandflächenwinkel zwischen den beiden Wandflächen einer Wandecke entspricht. Die ersten und zweiten Winkel α, β entsprechen einer Verdrehung der ersten Teilfläche T1 bezüglich der dritten Teilfläche T3 bzw. einer Verdrehung der zweiten Teilfläche T2 bezüglich der dritten Teilfläche T3 in einer Teilfläche, die senkrecht zu einer ersten und zweiten Schenkeloberfläche 15, 25 steht und die Mittellinien 12, 22 enthält. Die Schenkeloberfläche 15, 25 entspricht der Oberfläche des jeweiligen Schenkels 10, 20, an dem die Borsten 11, 21 angebracht sind.The bristles 11 ', 11 ", 11'" of the first, second and third groups T1, T2, T3 are attached to the first and second legs 10, 20, respectively, and the bristle length of the individual bristles 1 is chosen such that a formed between the first and third partial surface T1, T3 first angle α has a different value than a formed between the second and third partial surface T2, T3 second angle β. The value of the first and second angle a, b is chosen such that it corresponds approximately to the wall surface angle between the two wall surfaces of a wall corner. The first and second angles α, β correspond to a rotation of the first partial area T1 with respect to the third partial area T3 or a rotation of the second partial area T2 with respect to the third partial area T3 in a partial area which is perpendicular to a first and second leg surface 15, 25 and the center lines 12, 22 contains. The leg surface 15, 25 corresponds to the surface of the respective leg 10, 20, to which the bristles 11, 21 are attached.

Der sich zwischen der ersten und dritten Teilfläche T1 und T3 ausgebildete erste Winkel α weist einen Wert im Bereich von 130° bis 140°, vorzugsweise 135°, auf, und der sich zwischen der zweiten und dritten Teilfläche T2 und T3 ausgebildete zweite Winkel β weist einen Wert von 90° bis 100°, vorzugsweise 90° auf.The first angle α formed between the first and third partial surfaces T1 and T3 has a value in the range of 130 ° to 140 °, preferably 135 °, and has the second angle β formed between the second and third partial surfaces T2 and T3 a value of 90 ° to 100 °, preferably 90 °.

Die Borsten 11', 11", 11'" der ersten, zweiten und dritten Gruppe sind an dem Borstenhalter 2 derart angebracht, dass sich bei zumindest zwei Borsten ein sich zwischen dem jeweiligen Borsten und dem Borstenhalter 2 ausgebildeter Borstenhalterwinkel voneinander unterscheidet. Genauer gesagt weist mindestens ein Borstenhalterwinkel einen kleineren Wert als 90° auf. Es sind auch Ausführungsformen vorstellbar, in denen der Borstenhalterwinkel für alle Borsten 1 gleich ist.The bristles 11 ', 11 ", 11'" of the first, second and third groups are attached to the bristle holder 2 such that at least two bristles are interposed between the respective bristle and the bristle holder 2 trained Borstenhalterwinkel different from each other. More specifically, at least one bristle holder angle has a value smaller than 90 °. Embodiments are also conceivable in which the bristle holder angle is the same for all bristles 1.

Bei einem Reinigungsvorgang einer Wandecke, die einen 135° Wandflächenwinkel zwischen den Wandflächen aufweist, werden folgende Schritte durchgeführt. Zuerst wird der Staubwedel über das Koppelelement 31 mit einem Stiel gekoppelt. Durch den Stiel kann der Benutzer den Staubwedel einfach benutzen und das Reinigen von schwer zugänglichen Wandecken wird vereinfacht. Danach wird der Staubwedel in eine erste Position gebracht, in der die Borsten 11', 11"', die die erste und dritte Teilfläche T1, T3 bilden, den jeweiligen Wandflächen gegenüberliegen. D.h., dass der Staubwedel bezüglich der Wandflächen derart ausgerichtet wird, dass der erste Schenkel 10 einer Wandfläche und der Verbindungsabschnitt 4 der anderen Wandfläche jeweils gegenüberliegen. Da der erste Winkel a den gleichen Wert aufweist wie der Wandflächenwinkel kann ein Teil der Borsten 11, 21 in den Wandeckbereich eindringen, ohne dass diese Umknicken. Im Anschluss daran wird der Staubwedel entlang der Wandecke bewegt, so dass der sich in der Wandecke bzw. -kante befindenden Schmutz entfernt wird.In a cleaning operation of a wall corner having a 135 ° wall surface angle between the wall surfaces, the following steps are performed. First, the duster is coupled via the coupling element 31 with a handle. The handle allows the user to easily use the duster and makes it easier to clean hard-to-reach wall corners. Thereafter, the duster is brought to a first position in which the bristles 11 ', 11 "' forming the first and third sub-areas T1, T3 face the respective wall surfaces, that is, the duster is oriented with respect to the wall surfaces such that Since the first angle α has the same value as the wall surface angle, a part of the bristles 11, 21 can penetrate into the wall corner area without these being bent moves the duster along the wall corner, so that the located in the wall corner or edge dirt is removed.

Bei einem Reinigungsvorgang einer Wandecke, die einen 90° Wandflächenwinkel zwischen den Wandflächen aufweist, werden folgende von dem oben beschriebenen Reinigungsvorgang abweichende Schritte durchgeführt. Der Staubwedel 1 wird, nachdem dieser mit einer Stabvorrichtung gekoppelt ist, in eine zweite Position gebracht. In dieser zweiten Position liegen die Borsten 11", 11'", die die zweite und dritte Teilfläche T2, T3 bilden, den jeweiligen Wandflächen gegenüber. D.h., dass der Staubwedel bezüglich der Wandflächen derart ausgerichtet wird, dass der zweite Schenkel 20 einer Wandfläche und der Verbindungsabschnitt 4 der anderen Wandfläche jeweils gegenüberliegen. Anschließend kann der Schmutz aus dem Wandeckbereich entfernt werden, ohne dass die Borsten 1 umknicken.In a cleaning operation of a wall corner, which has a 90 ° wall surface angle between the wall surfaces, the following deviating from the above-described cleaning process steps are performed. The duster 1, after it is coupled to a rod device, placed in a second position. In this second position, the bristles 11 ", 11 '", which form the second and third partial surface T2, T3, face the respective wall surfaces. That is, the duster is aligned with respect to the wall surfaces so that the second leg 20 of a wall surface and the connecting portion 4 of the other wall surface are opposed to each other. Then the dirt can be removed from the wall corner area without the bristles 1 kinking.
