    Ein Bürstenvorsatzgerät des beschriebenen Aufbaus ist aus der Praxis bekannt und ermöglicht eine gründliche Reinigung ebener Bodenflächen, insbesondere von Glattböden und Teppichböden aus kurzer, harter Schlingenware. Bei der Saugreinigung von Bodenflächen, die z.B. durch aufliegende Teppiche verhältnismäßig uneben sind, und bei der Saugreinigung von hohen, weichen Velourböden ist die Funktion des Gerätes noch verbesserungsbedürftig. Beim Einsatz auf hochflorigen Teppichböden nimmt die Schiebekraft erheblich zu. Gleichzeitig neigt das Bürstenvorsatzgerät zu Kippbewegungen mit der Folge, daß die in Saugrichtung vordere Saugmundkante keinen definierten Bodenkontakt hat und der Saugunterdruck sowie die Saugwirkung abfallen kann.A brush attachment of the construction described is off known in practice and enables thorough cleaning flat floor surfaces, especially smooth floors and Carpets made of short, hard loop fabric. In the Suction cleaning of floor surfaces, e.g. by lying on Carpets are relatively uneven, and when vacuum cleaning of high, soft velor floors is the function of the device in need of improvement. When using on deep-pile carpets take the pushing force considerably to. At the same time, the brush attachment tends to tilt with the result that the front in the suction direction Suction mouth edge has no defined ground contact and the Suction negative pressure and the suction effect can drop.

    Der Erfindung liegt die Aufgabe zugrunde, ein Bürstenvorsatzgerät zur Saugreinigung von Bodenflächen anzugeben, das mit guter Saugwirkung auf unebenen Böden sowie auf unterschiedlichen Bodenbelägen, die von Glattböden bis hochflorigen Velourböden reichen, eingesetzt werden kann.The invention has for its object a brush attachment to specify for suction cleaning of floor surfaces, that with good suction on uneven floors as well as on different floor coverings, from smooth floors to deep-pile velor floors are sufficient.

    Ausgehend von einem Bürstenvorsatzgerät des eingangs beschriebenen Aufbaus wird die Aufgabe erfindungsgemäß dadurch gelöst, daß die Saugmundkanten sich vertikal beweglich an die Bodenfläche anpassen. Konstruktiv kann dies auf verschiedene Weise realisiert werden.Starting from a brush attachment at the entrance described construction, the task according to the invention solved in that the suction mouth edges are vertical adapt flexibly to the floor surface. Can be constructive this can be done in different ways.

    Gemäß einer ersten Ausführungsform der Erfindung ist die Bürstenwalzenkammer am Saugkanal oder am Gehäuseoberteil drehbeweglich gelagert und ist an die Bürstenwalzenkammer eine mit den Saugmundkanten ausgebildete Bodenplatte fest angeschlossen. Die Drehachse für die Schwenkbewegung der Bürstenwalzenkammer und die Rotationsachse der Bürstenwalze sind im wesentlichen fluchtend angeordnet. Durch eine Schwenkbewegung der Bürstenwalzenkammer passen sich die Saugmundkanten dem Bodenbelag selbsttätig an, wobei etwaige Kippbewegungen des Bürstenvorsatzgerätes ausgleichbar sind. According to a first embodiment of the invention Brush roller chamber on the suction channel or on the upper part of the housing rotatably mounted and is on the brush roller chamber a base plate formed with the suction mouth edges connected.

By a The swivel movement of the brush roller chamber adjust itself Suction mouth edges automatically on the flooring, taking any Tilting movements of the brush attachment can be compensated.

    Aus dem unterhalb der Saugmundkanten herrschenden Unterdruck resultieren Auflagekräfte, die symmetrisch zu der Schwenkachse der Bürstenwalzenkammer auf die Bodenplatte wirken und auch bei extremen Bodenbelägen, z.B. hochflorigen Velouren, eine planparallele Ausrichtung und damit einen ordnungsgemäßen Saugbetrieb sicherstellen.From the negative pressure below the edges of the suction mouth result in contact forces that are symmetrical to the Swivel axis of the brush roller chamber on the base plate act and also with extreme floor coverings, e.g. shaggy Velours, a plane-parallel orientation and thus ensure proper suction operation.

    Bei der beschriebenen Ausführung der Erfindung ist eine weitere Funktionsverbesserung erreichbar, wenn die Lageranordnung der Bürstenwalze vertikal verstellbar ausgeführt ist. Dabei liegt es im Rahmen der Erfindung, daß der Bodenabstand der Rotationsachse sich gegen die Wirkung von Rückstellfedern selbsttätig an dem Bodenbelag anpaßt oder manuell einstellbar ist. Durch die vertikale Einstellbarkeit der Bürstenwalze ist der bodenseitige Überstand der Bürstenwalze gegenüber den Saugmundkanten, die durch die erfindungsgemäße Lehre stets parallel zur Bodenfläche ausgerichtet sind und sich am Bodenbelag anpassen, veränderbar.In the described embodiment of the invention is a further functional improvement achievable if the bearing arrangement the brush roller is vertically adjustable is.

Due to the vertical adjustability the brush roller is the bottom overhang of the Brush roller opposite the suction mouth edges caused by the Teaching according to the invention always parallel to the floor surface are aligned and adapt to the flooring, changeable.

    Eine andere konstruktive Ausgestaltung der erfindungsgemäßen Lehre besteht darin, daß in Saugrichtung vor und hinter der Bürstenwalzenkammer vertikal bewegliche und an Druckfedern abgestützte Bodengleitstücke angeordnet sind, die jeweils eine Saugmundkante aufweisen. Durch das Wechselspiel zwischen Federkraft und Auflagekraft passen sich die Saugmundkanten unabhängig voneinander an den Bodenbelag an. Bei dieser Ausführung der Erfindung ist der bodenseitige Überstand der Bürstenwalze gegenüber den Saugmundkanten abhängig von dem jeweiligen Bodenbelag. Durch geeignete Festlegung der Federcharakteristik kann der sich einstellende Überstand so eingerichtet werden, daß auf allen Bodenbelägen ein optimales Saugergebnis resultiert. Eine federnde Aufhängung der Bürstenwalze erübrigt sich. Gemäß einer bevorzugten Ausführung der Erfindung ist die Bürstenwalze daher an einer gehäusefesten Lageranordnung rotierend gelagert.Another constructive embodiment of the invention Teaching is that before and in the suction direction behind the brush roller chamber vertically movable and on Bottom slides supported by compression springs are arranged, which each have a suction mouth edge. By the Interplay between spring force and contact force fit the suction mouth edges independently of each other Flooring. In this embodiment of the invention overhang of the brush roller on the bottom compared to the Suction mouth edges depending on the respective floor covering. By appropriately determining the spring characteristics, the adjusting supernatant can be set up so that All floor coverings have an optimal suction result. A resilient suspension of the brush roller is not necessary. According to a preferred embodiment of the invention Brush roller therefore on a housing-fixed bearing arrangement stored rotating.
