Description

Die Erfindung betrifft eine Anordnung zum lösbaren Verbinden eines Saugstutzens mit der Saugöffnung eines Staubsaugers gemäß dem Oberbegriff des Anspruches 1.The invention relates to an arrangement for releasably connecting a suction nozzle to the suction opening of a vacuum cleaner according to the preamble of claim 1.

Eine solche Anordnung ist durch die EP-B 0 212 313 bekannt. Bei dieser Anordnung sitzt das rohrförmige Ende des einen Rohrstutzens dicht auf einer an der Innenwand des anderen Rohrstutzens ausgebildeten Kante auf. Eine solche Abdichtung der Rohrstutzen gegeneinander ist in axialer Richtung sehr stark toleranzbehaftet. Außerdem kann es durch an einem Rohrstutzen wirksam werdende Zugkräfte zu einem Abheben des rohrförmigen Endes von der Kante kommen und somit die Dichtwirkung ebenfalls beeinträchtigt werden.Such an arrangement is known from EP-B 0 212 313. In this arrangement, the tubular end of one pipe socket sits tightly on an edge formed on the inner wall of the other pipe socket. Such a sealing of the pipe socket against each other is very tolerant in the axial direction. In addition, pulling forces acting on a pipe socket can result in the tubular end being lifted off the edge and the sealing effect also being impaired.

Der Erfindung liegt daher die Aufgabe zugrunde eine der gattungsgemäßen Art so weiterzubilden, daß eine sowohl von etwaigen Längstoleranzen der gegeneinander abzudichtenden Teile als auch von auf diese ausgeübten Zugkräften unbeeinflußte Abdichtung der gekoppelten Teile erreicht wird.The invention is therefore based on the object of developing a generic type in such a way that both the possible longitudinal tolerances of the parts to be sealed against one another and the tensile forces exerted on the sealing of the coupled parts are unaffected.

Die Lösung der gestelltten Aufgabe gelingt durch die im Kennzeichen des Anspruches 1 angegebenen Merkmale. Das mit dem freien Ende der rohrförmigen Verlängerung des Verriegelungselementes verbundene Dichtungselement ragt in axialer Richtung in den zwischen dem rohrförmigen Ende des Saugstutzens und der Saugöffnung des Staubsaugers bestehenden Ringspalt. Da das Dichtungselement in axialer Richtung an keiner Stelle aufliegt, wird bei einer axialen Bewegung des Saugstutzens oder bei axialen Längentoleranzen desselben die Dichtwirkung des Dichtungselementes in keiner Weise beeinflußt. Das Dichtungselement wird lediglich in axialer Richtung an der Wand der Saugöffnung entlang bewegt, ohne dadurch in seiner Dichtwirkung beeinflußt zu werden.The problem is solved by the features specified in the characterizing part of claim 1. The sealing element connected to the free end of the tubular extension of the locking element protrudes in the axial direction into the annular gap existing between the tubular end of the suction nozzle and the suction opening of the vacuum cleaner. Since the sealing element does not rest at any point in the axial direction, the sealing effect of the sealing element is in no way influenced in the event of an axial movement of the suction nozzle or in the event of axial length tolerances thereof. The sealing element is only on the wall in the axial direction moved along the suction opening without being affected by its sealing effect.

Zweckmäßigerweise ist als Dichtungselement an dem freien Ende der Verlängerung eine elastische Dichtlippe angeformt. Hierdurch erübrigt sich eine gesonderte Montage des Dichtungselementes.An elastic sealing lip is expediently formed as a sealing element on the free end of the extension. This makes a separate installation of the sealing element unnecessary.

Eine gute Dichtwirkung wird dadurch erreicht, daß als Dichtlippe an dem rohrförmigen Teil der Verlängerung ein schräg nach außen weisender Kragen angeformt ist.A good sealing effect is achieved in that an obliquely outwardly pointing collar is formed as a sealing lip on the tubular part of the extension.

Die an dem Verriegelungselement vorgesehene Verlängerung kann auch zur Arretierung des Verriegelungselementes genutzt werden, in dem an der Innenseite der rohrförmigen Verlängerung ein an dem rohrförmigen Ende des einen Rohrstutzens verrastbares Rastelement vorgesehen wird.The extension provided on the locking element can also be used for locking the locking element, in that a latching element which can be locked on the tubular end of the one pipe socket is provided on the inside of the tubular extension.

Anhand eines in der Zeichnung dargestellten Ausführungs-beispieles wird die Erfindung nachfolgend noch n näher beschrieben.
Es zeigt:

FIG 1
eine Anordnung zum lösbaren Verbinden eines Saugstutzens mit der Saugöffnung eines Staubsaugers im Halbschnitt,
FIG 2
eine Seitenansicht eines Saugstutzens.
Using an exemplary embodiment shown in the drawing, the invention is described in more detail below.
It shows:
FIG. 1
an arrangement for releasably connecting a suction nozzle to the suction opening of a vacuum cleaner in half section,
FIG 2
a side view of a suction nozzle.

Mit 1 ist ein Wandteil eines andeutungsweise dargestellten Staubsaugergehäuses bezeichnet. An dem Wandteil 1 ist die Saugöffnung des Staubsaugers vorgesehen. An diese Saugöffnung 2 ist ein mit einem Saugschlauch verbundener Saugstutzen 3 ankoppelbar. Die Saugöffnung 2 bildet somit einen mit dem Saugstutzen 3 koppelbaren anderen Rohrstutzen. Der eine Saugstutzen 3 weist ein in die Saugöffnung 2 einsteckbares rohrförmiges Ende 4 auf, das auf eine bestimmte axiale Länge von einem Rohransatz 5 des Saugstutzens 3 mit radialem Abstand umgeben ist. Auf diese Weise ergibt sich zwischen dem rohrförmigen Ende 4 und dem Rohransatz 5 ein Ringraum 6.1 with a wall part of a hinted vacuum cleaner housing is designated. The suction opening of the vacuum cleaner is provided on the wall part 1. A suction nozzle 3 connected to a suction hose can be coupled to this suction opening 2. The suction opening 2 thus forms another pipe socket which can be coupled to the suction socket 3. One suction nozzle 3 has a tubular end 4 which can be inserted into the suction opening 2 and which has a radial distance from a tube extension 5 of the suction nozzle 3 to a certain axial length is surrounded. In this way, an annular space 6 results between the tubular end 4 and the tube extension 5.

In dem Ringraum 6 ist ein Verriegelungselement 7 eingesetzt. Das Verriegelungselement 7 weist einen zu dem rohrförmigen Ende 4 konzentrischen Ringteil 8 auf. An dem Ringteil 8 sind zwei nach radial außen vorstehende Rastnocken 9 angeformt, die jeweils durch eine Schlitz 10 des Rohransatzes 5 hindurch ragen und einen am Wandteil 1 angeformtem Rastvorsprung 11 untergreifen. Hierdurch wird der Saugstutzen 3 am Staubsaugergehäuse in der Saugöffnung 2 gehalten. Axial oberhalb jeder Rastnocke 9 ist jeweils eine durch eine entsprechende Öffnung 12 in der Wand des Saugstutzens 3 nach außen ragende Entriegelungstaste 13 an dem Ringteil 8 vorgesehen. Zum Entkoppeln des Saugstutzens 3 von der Saugöffnung 2 wird auf die Entriegelungstasten 13 ein entsprechender Druck ausgeübt. Hierdurch wird der Ringteil 8 entsprechend nach radial innen verformt, so daß die Rastnasen 9 außer Eingriff mit dem Rastvorsprung 11 kommen und der Saugstutzen 3 aus der Saugöffnung 2 herausgezogen werden kann.A locking element 7 is inserted in the annular space 6. The locking element 7 has a ring part 8 which is concentric with the tubular end 4. On the ring part 8 two radially outwardly projecting locking cams 9 are formed, each of which protrude through a slot 10 of the tubular extension 5 and engage under a locking projection 11 formed on the wall part 1. As a result, the suction nozzle 3 is held on the vacuum cleaner housing in the suction opening 2. Axially above each latching cam 9, an unlocking button 13 projecting outward through a corresponding opening 12 in the wall of the suction nozzle 3 is provided on the ring part 8. To decouple the suction nozzle 3 from the suction opening 2, a corresponding pressure is exerted on the unlocking buttons 13. As a result, the ring part 8 is correspondingly deformed radially inward, so that the locking lugs 9 disengage from the locking projection 11 and the suction nozzle 3 can be pulled out of the suction opening 2.

An dem Verriegelungselement 7 ist ferner eine rohrförmige Verlängerung 14 vorgesehen. Der Innendurchmesser dieser Verlängerung 14 entspricht dem Außendurchmesser des rohrförmigen Endes 4 des Saugstutzens 3, so daß das Verriegelungselement 7 mit seiner Verlängerung 14 auf das rohrförmige Ende 4 des Saugstutzens 3 aufschiebbar ist. An der Innenwand der Verlängerung 14 sind Rastnasen 15 vorgesehen, die in entsprechend angepaßte Rastvertiefungen 16 des rohrförmigen Endes 4 eingreifen. Die Rastnasen 15 und die Rastvertiefungen 16 sind so geformt, daß in Aufschieberichtung des Verriegelungselementes 7 eine Verrastung erfolgt, die in der zu der Aufschieberichtung entgegengesetzten Richtung nicht mehr lösbar ist. Durch die durch die Öffnung 12 ragenden Entriegelungstasten 13 wird die Aufschiebestrecke des Verriegelungselementes 7 derart begrenzt, daß die Rastnasen 15 in Anlage an der Rastkante 17 der Rastvertiefung 16 verbleiben.A tubular extension 14 is also provided on the locking element 7. The inner diameter of this extension 14 corresponds to the outer diameter of the tubular end 4 of the suction nozzle 3, so that the locking element 7 with its extension 14 can be pushed onto the tubular end 4 of the suction nozzle 3. On the inner wall of the extension 14 locking lugs 15 are provided which engage in correspondingly adapted locking recesses 16 of the tubular end 4. The locking lugs 15 and the locking recesses 16 are shaped so that in the pushing-on direction of the locking element 7 there is a locking which can no longer be released in the opposite direction to the pushing-on direction. The push-on distance of the locking element 7 is limited by the unlocking buttons 13 protruding through the opening 12 in such a way that the locking lugs 15 remain in contact with the locking edge 17 of the locking recess 16.

An dem freien Ende der Verlängerung 14 ist als Dichtungselement ein schräg nach radial außen weisender Kragen 18 angeformt, der wiederum an seinem freien Ende mit einer Dichtlippe 19 versehen ist. Der Außendurchmesser der Dichtlippe 19 ist im nicht in die Saugöffnung 2 eingesteckten Zustand des Saugstutzens 3 geringfügig größer bemessen als der Innendurchmesser der Saugöffnung 2 in dem Bereich, in dem sich die Dichtlippe 19 im an die Saugöffnung 2 angekoppelten Zustand des Saugstutzens 3 befindet. Somit wird sicher gestellt, daß sich die Dichtlippe 19 beim Ankoppeln des Saugstutzens 3 an die Saugöffnung 2 unter einem gewissen Spannungszustand an die Wand 20 der Saugöffnung 2 anlegt. Damit ist eine einwandfreie Abdichtung der Koppelstelle des Saugstutzens 3 an die Saugöffnung 2 gewährleistet. Die Güte der Abdichtstelle hängt nicht mehr von irgendwelchen Längentoleranzen der ineinandergefügten Teile ab. Auch haben auf den Saugstutzen 3 ausgeübte Zugkräfte keinen Einfluß mehr auf die Dichtwirkung. Derartige Einflüsse können lediglich zu einer axialen Verschiebung der Berührungslinie der Dichtlippe 19 mit der Wand 20 der Saugöffnung 2 führen.At the free end of the extension 14 a collar 18 is formed obliquely to the radially outward as a sealing element, which in turn is provided at its free end with a sealing lip 19. The outside diameter of the sealing lip 19 is dimensioned slightly larger than the inside diameter of the suction opening 2 in the area in which the sealing lip 19 is in the state of the suction port 3 coupled to the suction opening 2 when the suction port 3 is not inserted into the suction port 2. This ensures that the sealing lip 19 bears against the wall 20 of the suction opening 2 when the suction nozzle 3 is coupled to the suction opening 2 under a certain state of tension. This ensures a perfect seal between the coupling point of the suction nozzle 3 and the suction opening 2. The quality of the sealing point no longer depends on any length tolerances of the parts that are joined together. Also, tensile forces exerted on the suction nozzle 3 no longer have any influence on the sealing effect. Such influences can only lead to an axial displacement of the line of contact of the sealing lip 19 with the wall 20 of the suction opening 2.
