Description

Die Erfindung bezieht sich auf einen Saugvorsatz für ein Bodenpflegegerät, insbesondere Staubsauger, zur verschwenkbaren und drehbeweglichen Verbindung über einen Anschluß des Saugvorsatzes mit einem Sauganschluß und Handhabe des Bodenpflegegerätes, wobei ein Schwenkelement am Saugvorsatz schwenkbar angeordnet ist und mit einem korrespondierenden Drehelement, das einen Anschluß zum Bodenpflegegerät bildet, zur drehbeweglichen Verbindung gekoppelt ist sowie Schwenkelement und Drehelement ineinander greifen und im Verbindungsbereich von Schwenkelement und Drehelement über eine Nut im Schwenkelement und korrespondierende Elemente am Drehelement eine Führung durchführbar ist.The invention relates to a suction attachment for a floor care device, in particular vacuum cleaner, for pivotable and rotatable connection via a connection of the suction attachment with a suction port and handle of the floor care device, wherein a pivot member is pivotally mounted on the suction attachment and with a corresponding rotary member having a connection to Floor care device forms, is coupled to the rotatable connection and pivot element and rotary element interlock and in the connection region of the pivot member and rotary member via a groove in the pivot member and corresponding elements on the rotary member a guide is feasible.

Es hat sich gezeigt, daß es relativ aufwendig ist, eine verschwenkbare und drehbewegliche Zuordnung eines Saugvorsatzes auszubilden. Hierbei besteht das besondere Problem darin, daß der Gelenkbereich montagefreundlich zu gestalten ist, um eine erforderliche robuste Ausbildung unter Berücksichtigung des Einsatzes für Bodenpflegegeräte und den entsprechenden Einsatzzwecken zu ermöglichen.It has been found that it is relatively complicated to form a pivotable and rotatable association of a suction attachment. Here, the particular problem is that the joint area is designed to be easy to install, to allow a required robust training, taking into account the use of floor care equipment and the corresponding applications.

Es sind eine Vielzahl von Gelenkverbindungen bekannt geworden, die aber im wesentlichen keine einfache Montage und Demontage ermöglichen bzw. es Schwierigkeiten gibt, die aus Kunststoff ausgebildeten Elemente zur Kraftübertragung heranzuziehen.There are a variety of joints have become known, but essentially do not allow easy assembly and disassembly or there are difficulties to use the plastic-formed elements for power transmission.

Nach der JP 11206654 A ist es bekannt, durch eine Anordnung von zwei einsetzbaren und festlegbaren Führungselementen in Öffnungen eines Drehelementes die Führungselemente einer korrespondierenden Nut des Schwenkelementes zuzuordnen, um dadurch eine Führung und Halterung zu erzielen. Hierdurch wird keine robuste Zuordnung von Schwenk- und Drehelement gewährleistet und durch die äußere Zugänglichkeit der Führungselemente keine Absicherung erreicht.After JP 11206654 A It is known to assign by an arrangement of two usable and fixable guide elements in openings of a rotary element, the guide elements of a corresponding groove of the pivot member, thereby achieving a guide and support. As a result, no robust assignment of pivoting and rotating element is ensured and achieved by the external accessibility of the guide elements no hedging.

Die Aufgabe der Erfindung ist es, eine gattungsgemäße Anordnung eines Saugvorsatzes zur Verbindung mit einem Bodenpflegegerät durch einfachere Mittel zu schaffen, die eine Halterung und Führung gewährleistet und eine Montage sowie Demontage von relativ dicht zugeordneten Elementen gewährleistet.The object of the invention is to provide a generic arrangement of a suction attachment for connection to a ground care device by simpler means, which ensures a holder and guide and ensures assembly and disassembly of relatively tightly associated elements.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß, dadurch gekennzeichnet, daß jeweils umlaufende, einander zugeordnete Nuten am Schwenkelement und Drehelement zur Aufnahme von Teilstücken und Ausbildung eines Führungs- und Halteringes aufweisen, wobei die Teilstücke über mindestens eine durch ein oder mehrere Verschlußelemente abgedeckbare und/oder absperrbare Öffnung im außen liegenden Element in die Nuten einsetzbar sind.The solution of this object is achieved according to the invention, characterized in that each circumferential, mutually associated grooves on the pivot member and rotary member for receiving sections and forming a guiding and retaining ring, said sections over at least one coverable by one or more closure elements and / or lockable Opening in the outer element can be inserted into the grooves.

Hierdurch ist es möglich, ein Drehelement und ein Schwenkelement relativ mit kleinem Spiel zu verbinden und die Teilstücke in die Nuten zur Bildung eines Führungs- und Halteringes einzusetzen.This makes it possible to connect a rotary member and a pivot member relative to a small game and insert the sections into the grooves to form a guiding and retaining ring.

Eine günstige Ausbildung wird dadurch geschaffen, daß das Drehelement im Verbindungsbereich zum Schwenkelement hülsenförmig über das Schwenkelement greift. Alternativ ist vorgesehen, daß das Schwenkelement im Verbindungsbereich zum Drehelement hülsenförmig über das Drehelement greift.A favorable education is created by the fact that the rotary member engages in the connecting area to the pivot member sleeve-shaped over the pivot member. Alternatively, it is provided that the pivot member engages sleeve-shaped over the rotary member in the connection region to the rotary member.

Um eine Fixierung der eingesetzten Teilstücke zu ermöglichen, wird vorgeschlagen, daß eine der Nuten mindestens eine begrenzte taschenförmige Aufnahme zur Fixierung eines oder mehrere Teilstücke aufweist.In order to enable a fixation of the inserted sections, it is proposed that one of the grooves has at least one limited pocket-shaped receptacle for fixing one or more sections.

Um eine Ruheposition sicher einzustellen, wird vorgeschlagen, daß in einer vorbestimmten Mittelstellung des Drehelementes und senkrechter Ausrichtung des Schwenkelementes als Ruhestellung, eine im Schwenkelement gelagerte federbelastete Raste in ein im Drehelement ausgebildetes Gegenlager eingreift.In order to set a rest position safely, it is proposed that engages in a predetermined center position of the rotary member and vertical orientation of the pivot member as a rest position, a spring-loaded detent mounted in the pivot member in a counter-bearing formed in the rotary member.

Ferner wird vorgeschlagen, daß das Schwenkelement über ein zugeordnetes Verriegelungselement gegen eine Abkippbewegung blockierbar ist. Hierzu ist vorgesehen, daß das Verriegelungselement durch eine fußbetätigte Wippe am Saugvorsatz gebildet ist.It is also proposed that the pivoting element can be blocked via an associated locking element against a tilting movement. For this purpose, it is provided that the locking element is formed by a foot-actuated rocker on the suction attachment.

Eine funktionssichere Anordnung wird dadurch geschaffen, daß ein Verschlußelement durch eine verriegelbare Abdeckung am hülsenförmigen Element gebildet ist.A functionally reliable arrangement is provided in that a closure element is formed by a lockable cover on the sleeve-shaped element.

Um die Öffnung zur Einführung der Teilstücke relativ klein zu halten, wird vorgeschlagen, daß mindestens vier Teilstücke zur Bildung eines Führungs- und Halteringes in die Nuten von Schwenk- und Drehelement einsetzbar sind.In order to keep the opening for the introduction of the sections relatively small, it is proposed that at least four sections to form a guiding and retaining ring can be inserted into the grooves of the pivoting and rotating element.

Weiterhin ist vorgesehen, daß in und zwischen dem Schwenkelement und Drehelement ein taschenförmiger Zwischenraum zur beweglichen Aufnahme elektrischer Leiter ausgebildet ist.Furthermore, it is provided that in and between the pivoting element and rotating element a pocket-shaped intermediate space for the movable recording of electrical conductors is formed.

Eine günstige Ausbildung wird dadurch geschaffen, daß das Drehelement Bestandteil des Bodenpflegegerätes ist, das in der Verbindungsstelle zum Schwenkelement an den Saugvorsatz koppelbar ist.A favorable education is created by the fact that the rotary element is part of the floor care device, which can be coupled to the suction attachment in the connection point to the pivoting element.

Ferner ist vorgesehen, daß der Verbindungsbereich zwischen Schwenkelement und Drehelement zur Aufnahme der Nuten wulstartig ausgebildet ist.It is further provided that the connection region between the pivot element and the rotary member for receiving the grooves is formed like a bead.
