Description

Die Erfindung bezieht sich auf ein Bodenpflegegerät als Bürststaubsauger, bestehend aus einem in dem Boden zugewandten Bürstvorsatz mit einer angetriebenen Bürstwalze und einem Sauggebläse, wobei über ein verschwenkbares Verbindungselement ein Filtergehäuse mit einer Handhabe verbunden ist, wobei ein elektrisches Sauggebläse die mit Schmutz beladene Luft über eine Steigleitung in einen oberen Bereich des Filtergehäuses führt und die Steigleitung mit einem starren Handsaugrohr für Nebensaugarbeiten lösbar am Filtergehäuse angeordnet ist, wobei der Bürstvorsatz Laufrollen aufweist, und wobei wenigstens eine Laufrolle zur Anpassung der Bürstwalze an die vorliegenden Arbeitsverhältnisse zur Verstellung der Bürstwalze gegenüber dem Boden höhenverstellbar angeordnet ist.The invention relates to a floor care device as Bürststaubsauger, consisting of a facing in the floor brush attachment with a driven brush roller and a suction fan, via a pivotable connecting element, a filter housing is connected to a handle, wherein an electric suction fan, the dirt-laden air over a Riser leads into an upper region of the filter housing and the riser is arranged with a rigid hand suction for suctions detachable on the filter housing, wherein the brush attachment has rollers, and wherein at least one roller for adjusting the brush roller to the present working conditions for adjusting the brush roller relative to the ground height adjustable is arranged.

Es ist bei Anordnungen dieser Art bekannt, eine Höhenverstellung für die Bürstwalze in unterschiedlicher Weise vorzunehmen, um eine Anpassung der Bürstwalze an die vorliegenden Arbeitsverhältnisse, wie Untergrund-beschaffenheit und Bürstenabnutzung, vorzunehmen. Im Wesentlichen sind elektrische/elektronische Verstellvorrichtungen bekannt, um die Verstellung der Bürstwalze vorzunehmen und gleichförmige Auflagekräfte der Bürstwalze unabhängig vom Untergrund zu gewährleisten. Diese bekannten Ausbildungen sind relativ aufwendig und empfindlich. Ferner ist es bekannt, durch manuelle Einstellungen einer Laufrolle die Bürstwalze im Abstand zum Boden einzustellen. Hierbei hat sich gezeigt, dass die Einstellung wegen der Handhabung in der Praxis nicht durchgeführt wird, da die Zugänglichkeit nicht bedienerfreundlich ist bzw. die Bedienung nur am Boden durchführbar ist. Druckschriftlicher Stand der Technik ist in der US 2007/209144 A1 , der US 2 734 217 A und in der US 2009/044374 A1 , wobei die US 2009/044374 A1 dem Oberbegriff des unabhängigen Anspruchs 1 entspricht.It is known in arrangements of this type, to perform a height adjustment for the brush roller in different ways to make an adjustment of the brush roller to the existing working conditions, such as subsurface texture and brush wear. Essentially, electrical / electronic adjusting devices are known to carry out the adjustment of the brushing roller and to ensure uniform support forces of the brushing roller independently of the substrate. These known embodiments are relatively expensive and delicate. Furthermore, it is known to set the brush roller at a distance from the ground by manual adjustment of a roller. It has been shown that the adjustment is not carried out because of the handling in practice, since the accessibility is not user-friendly or the operation is carried out only on the ground. Prior art is in the US 2007/209144 A1 , of the US 2 734 217 A and in the US 2009/044374 A1 , where the US 2009/044374 A1 the preamble of independent claim 1 corresponds.

Die Aufgabe der Erfindung ist es, eine Verbesserung von mechanischen Einstellvorrichtungen für Bürstwalzen von gattungsgemäßen Bodenpflegegeräten zu schaffen, die eine bedienungsfreundliche Höhenverstellung der Bürstwalze ermöglicht.The object of the invention is to provide an improvement of mechanical adjustment devices for brush rollers of generic floor care equipment that allows easy adjustment of the height of the brush roller.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, dass die höhenverstellbare Laufrolle im Bürstvorsatz über einen Drucktaster als Betätigungselement im oben liegenden Gehäusebereich des Bürstvorsatzes auf eine mehrstufig schaltbare Raste einer Weiterschaltmechanik zur Höhenverstellung der Laufrolle über eine verstellbare Stellachse gekoppelt ist, und dass das lösbare Handsaugrohr des Filtergehäuses als Betätigungselement einer Steuerfläche des Drucktasters am Bürstvorsatz dient, wobei die Steuerfläche des Drucktasters eine Aufnahme zur korrespondieren Aufnahme eines Randbereiches des Handsaugrohres aufweist.The solution of this object is achieved according to the invention in that the height-adjustable roller is coupled in the brush attachment via a push button as an actuator in the overhead housing portion of the brush attachment to a multi-stage switchable latch a Weiterschaltmechanik for adjusting the height of the roller via an adjustable adjusting axis, and that the detachable Handsaugrohr the filter housing serves as an actuating element of a control surface of the pushbutton on the brush attachment, wherein the control surface of the pushbutton has a receptacle for receiving a corresponding corresponding edge region of the Handsaugrohres.

Hierdurch wird ermöglicht, dass durch den im oberen liegenden Gehäusebereich des Bürstvorsatzes die Höheneinstellung durch das lösbare Handsaugrohr aus dem Stand des Bedieners durchführbar ist.This makes it possible that by adjusting the height in the upper housing portion of the brush attachment height adjustment by the detachable hand suction from the operator's position is feasible.

Zur Verbesserung der Betätigung ist bei einem Ausführungsbeispiel vorgesehen, dass die Steuerfläche des Drucktasters eine Fuge bzw. Vertiefung als Aufnahme zur korrespondieren Aufnahme eines Randbereiches des Handsaugrohres aufweist. Durch die Fuge wird somit eine seitliche Anlagefläche für das Handsaugrohr geschaffen, die eine sichere Wirkverbindung zwischen dem Handsaugrohr und dem Druckschalter bei Druckbetätigung ermöglicht und ein Wegrutschen des Handsaugrohrs bei Druckbetätigung verhindert.To improve the operation is provided in one embodiment, that the control surface of the pushbutton has a groove or recess as a receptacle for receiving a corresponding corresponding edge portion of the Handsaugrohres. The joint thus creates a lateral contact surface for the hand suction tube, which enables a secure operative connection between the hand suction tube and the pressure switch during pressure actuation and prevents the hand suction tube from slipping out under pressure.

Bei einem alternativen Ausführungsbeispiel ist vorgesehen, dass die Steuerfläche des Drucktasters eine Erhebung als Aufnahme zur korrespondieren Aufnahme eines Randbereiches des Handsaugrohres aufweist. Die Erhebung kann beispielsweise ein Steg, eine Rippe, zumindest ein Stift bzw. Pin und dergleichen sein. Somit wird analog zur Vertiefung durch die Erhebung eine seitliche Anlagefläche für das Handsaugrohr geschaffen, die eine sichere Wirkverbindung zwischen dem Handsaugrohr und dem Druckschalter bei Druckbetätigung ermöglicht und ein Wegrutschen des Handsaugrohrs bei Druckbetätigung verhindert.In an alternative embodiment, it is provided that the control surface of the pushbutton a survey as a receptacle for receiving a corresponding corresponding edge of the hand suction having. The survey may be, for example, a web, a rib, at least one pin or pin and the like. Thus, a lateral contact surface for the Handsaugrohr is created analogous to the recess by the survey, which allows a secure operative connection between the Handsaugrohr and the pressure switch with pressure actuation and prevents slippage of Handsaugrohrs under pressure.

Zudem kann die Steuerfläche einen Betätigungsabschnitt zur Fußbetätigung aufweisen bzw. die Aufnahme derart ausgebildet sein, dass eine Fußbetätigung gewährleistet ist. Durch die Fußbetätigung ist ebenfalls eine Höhenverstellung aus dem Stand des Bedieners durchführbar.In addition, the control surface can have an actuating section for foot actuation or the receptacle can be designed such that a foot actuation is ensured. By foot control is also a height adjustment from the state of the operator feasible.

Eine vorteilhafte Anordnung besteht darin, dass der Drucktaster im Randbereich des Gehäuses des Bürstvorsatzes angeordnet ist.An advantageous arrangement is that the pushbutton is arranged in the edge region of the housing of the brush attachment.

Um die aktuelle Höheneinstellung zu dokumentieren, ist vorgesehen, dass die mehrstufige schaltbare Raste mit einem rotierenden Element zur Stellungsanzeige verbunden ist, die über ein Sichtfenster im Bürstvorsatz als eingestellte Höheneinstellung der Laufrolle anzeigbar ist.In order to document the current height setting, it is provided that the multi-stage switchable detent is connected to a rotating element for position indication, which can be displayed via a viewing window in the brush attachment as a set height adjustment of the roller.
