Description

Die Erfindung betrifft eine Vorrichtung zum lösbaren Befestigen eines Staubfilterbeutels in einem staubsaugenden Gerät, mit einem außen an der Beutelwandung sitzenden Flanschteil aus steifem Material, das eine mit einer Eintrittsöffnung in der Beutelwandung fluchtende Durchtrittsöffnung aufweist, und einer gerätespezifischen Adapterplatte aus steifem Material, die einerseits am staubsaugenden Gerät festlegbar und andererseits mit dem Flanschteil durch eine Steck- und Rastverbindung lösbar verbindbar ist, wobei die Adapterplatte eine im verbundenen Zustand mit der Durchtrittsöffnung des Flanschteils fluchtende und zusammen mit dieser eine Durchströmöffnung bildende Durchgangsöffnung aufweist und eine im verbundenen Zustand zwischen der Adapterplatte und dem Flanschteil wirksame Ringdichtung zum Abdichten der Durchströmöffnung nach außen hin vorhanden ist.The invention relates to a device for releasably attaching a dust filter bag in a vacuum cleaner, with a seated on the outside of the bag wall flange of rigid material having a aligned with an inlet opening in the bag wall opening, and a device-specific adapter plate made of rigid material, on the one hand am dust-sucking device can be fixed and on the other hand detachably connected to the flange by a plug-in and locking connection, wherein the adapter plate has a connected in the connected state with the passage opening of the flange and aligned with this one through-opening forming a through-opening between the adapter plate and the Flange part effective ring seal is present for sealing the flow opening to the outside.

Bei staubsaugenden Geräten werden zum Sammeln des anfallenden Staubes Filterbeutel verwendet. Dabei wird mittels eines Gebläses ein Saugstrom erzeugt, der den Staub in einen Saugschlauch oder dergleichen zieht und von dort durch die Eintrittsöffnung in den Filterbeutel fördert. Der in der angesaugten Luft enthaltene Staub wird von der Beutelwandung zurückgehalten. Der vom Staub befreite Luftstrom durchdringt die Beutelwandung und wird anschließend in die Umgebung ausgeblasen. Ist der Filterbeutel voll, wird er entnommen und kann weggeworfen werden. Sodann wird ein neuer Filterbeutel in das staubsaugende Gerät eingesetzt.In vacuuming devices filter bags are used to collect the accumulated dust. In this case, by means of a blower, a suction flow is generated which pulls the dust into a suction hose or the like and from there through the inlet opening into the filter bag. The dust contained in the intake air is retained by the bag wall. The dust-free air flow penetrates the bag wall and is then blown into the environment. If the filter bag is full, it is removed and can be thrown away. Then a new filter bag is inserted into the vacuuming device.

Das Festlegen des Filterbeutels am staubsaugenden Gerät erfolgt üblicherweise mittels eines außen an der Beutelwandung im Bereich der Eintrittsöffnung angebrachten und eine mit der Eintrittsöffnung fluchtende Durchströmöffnung enthaltenden Anschlussstücks, das mit einer geräteseitigen Halterung in Eingriff gebracht wird. Die auf dem Markt befindlichen Staubsauger unterschiedlicher Hersteller weisen jedoch regelmäßig unterschiedliche Halterungen auf, so dass eine entsprechende Anzahl von Filterbeuteltypen bereitgestellt werden muss, die jeweils ein anderes Anschlussstück aufweisen. Dies ist aufwendig.The setting of the filter bag on the vacuuming device is usually carried out by means of an externally attached to the bag wall in the region of the inlet opening and a flush with the inlet opening containing connection piece, which is brought into engagement with a device-side holder. However, the vacuum cleaner of different manufacturers on the market regularly have different brackets, so that a corresponding number of filter bag types must be provided, each having a different connector. This is expensive.

Daher wird in der DE 20 2004 020 775 U1 eine Vorrichtung der eingangs genannten Art vorgeschlagen, die es ermöglicht, gleich ausgebildete Staubfilterbeutel für staubsaugende Geräte mit unterschiedlichen Halterungen zu verwenden. Hierzu wird das bis dahin übliche Anschlussstück aufgeteilt in eine Adapterplatte und ein am Filterbeutel sitzendes Flanschteil, wobei die Adapterplatte einerseits an die Halterung des betreffenden Staubsaugers angepasst ist und andererseits mit dem stets gleich bleibenden Flanschteil verbunden werden kann. Auf diese Weise kann der unverändert bleibende Staubfilterbeutel für staubsaugende Geräte mit unterschiedlichen Halterungen verwendet werden, da die Anpassung an die jeweilige Halterung durch die Adapterplatte erfolgt. Somit müssen nur noch an die verschiedenen Halterungen angepasste Adapterplatten bereitgestellt werden, die alle lösbar mit dem stets gleichen Filterbeutel-Flanschteil verbindbar sind. Seitens des Herstellers müssen lediglich mehrere jeweils an eine der verschiedenen Halterungen unterschiedlicher staubsaugender Geräte angepasste Adapterplatten angeboten werden, die alle mit einem gleichen Flanschteil lösbar verbindbar sind. Der Verbraucher muss dann nur die zu seinem Staubsauger passende Adapterplatte auswählen, die er dann für alle von ihm gekauften Filterbeutel verwenden kann. Die Adapterplatte kann dauerhaft, auch bei einem Wechsel des Filterbeutels, im Staubsauger verbleiben oder beim Filterbeutelwechsel zusammen mit dem Filterbeutel entnommen und außerhalb des Staubsaugers mit dem Flanschteil eines neuen Filterbeutels verbunden und dann wieder eingesetzt werden.Therefore, in the DE 20 2004 020 775 U1 proposed a device of the type mentioned above, which makes it possible to use the same trained dust filter bag for vacuuming devices with different brackets. For this purpose, the hitherto customary connector is divided into an adapter plate and a seated on the filter bag flange, wherein the adapter plate is adapted on the one hand to the holder of the respective vacuum cleaner and on the other hand can be connected to the always constant flange. In this way, the dust filter bag remaining unchanged for vacuuming devices can be used with different brackets, since the adaptation to the respective holder is done by the adapter plate. Thus, only adapted to the different brackets adapter plates must be provided, all of which are detachably connected to the same filter bag flange part always. On the part of the manufacturer, only a plurality of adapter plates each adapted to one of the various holders of different vacuuming devices have to be offered, all of which can be detachably connected to a same flange part. The consumer then only needs to select the matching his vacuum cleaner adapter plate, which he can then use for all the filter bag he bought. The adapter plate can permanently, even with a change of the filter bag, remain in the vacuum cleaner or removed with the filter bag change together with the filter bag and connected outside the vacuum cleaner with the flange of a new filter bag and then used again.

In der WO 92/13479 A ist eine Schließvorrichtung für ein Staubfilterbeutel in einem Staubsauger offenbart. Der Staubfilterbeutel besitzt ein außen an der Beutelwandung sitzendes Flanschteil mit einer Durchtrittsöffnung, die mit der in der Beutelwandung vorgesehenen Eintrittsöffnung fluchtet. Das Flanschteil besitzt an seiner der Beutelwandung abgewandten Vorderseite eine Rastaufnahme, die auf einen flanschartigen, staubsaugerseitigen Stutzen aufgerastet werden kann, wodurch der Staubfilterbeutel am Staubsauger befestigt ist.In the WO 92/13479 A discloses a closure device for a dust filter bag in a vacuum cleaner. The dust filter bag has a seated on the outside of the bag wall flange with a passage opening which is aligned with the provided in the bag wall inlet opening. The flange has on its side facing away from the bag wall front a locking receptacle which can be snapped onto a flange, vacuum cleaner side nozzle, whereby the dust filter bag is attached to the vacuum cleaner.

Aus der US-A1-3 683 599 ist ein Staubsauger bekannt, bei dem ein Staubfilterbeutel über eine Adapterplatte mit dem staubsaugerseitigen Auslassbereich eines Saugkanals verbunden wird. An der Adapterplatte kann hierbei einerseits der Staubfilterbeutel befestigt werden und andererseits ist eine Befestigung am Auslassbereich des Saugkanals des Staubsaugers möglich.From the US-A1-3,683,599 a vacuum cleaner is known in which a dust filter bag is connected via an adapter plate with the vacuum cleaner side outlet region of a suction channel. On the one hand, the dust filter bag can be attached to the adapter plate and, on the other hand, attachment to the outlet region of the suction channel of the vacuum cleaner is possible.

Ausgehend hiervon liegt der vorliegenden Erfindung die Aufgabe zu Grunde, eine Vorrichtung der eingangs genannten Art zu schaffen, bei der sich unter Beibehaltung der geschilderten Vorteile in der Gebrauchslage, wenn die Adapterplatte und das Flanschteil miteinander verbunden sind, eine besonders effektive Abdichtung der Schnittstelle zwischen Adapterplatte und Flanschteil und somit der Durchströmöffnung nach außen hin ergibt.Proceeding from this, the present invention, the object of the invention to provide a device of the type mentioned, in which, while maintaining the described Advantages in the position of use, when the adapter plate and the flange are connected to each other, a particularly effective sealing of the interface between the adapter plate and flange and thus the flow-through opening to the outside results.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Flanschteil radial außerhalb der Ringdichtung in von der Adapterplatte weg geneigter Schrägstellung an die Adapterplatte ansteckbar und im angesteckten Zustand schwenkbar mit der Adapterplatte verbunden ist, so dass das Flanschteil zur Adapterplatte hin in eine koaxial zu Adapterplatte angeordnete, mit der Adapterplatte verrastete Gebrauchslage schwenkbar ist, in der eine Dichtfläche des Flanschteils oder der Adapterplatte gegen die an der Adapterplatte bzw. am Flanschteil angeordnete Ringdichtung gehalten wird.This object is achieved in that the flange radially outwardly of the ring seal in the adapter plate away inclined position on the adapter plate is connected and pivotally connected in the infected state with the adapter plate, so that the flange to the adapter plate arranged in a coaxial with the adapter plate, With the adapter plate latched position of use is pivotable, in which a sealing surface of the flange or the adapter plate is held against the arranged on the adapter plate and the flange part ring seal.

Durch das schräge Anstecken wird das Flanschteil in die richtige Position gebracht, so dass sich die Gebrauchslage nach dem Verschwenken des Flanschteils und dem Verrasten sozusagen von selbst ergibt. Dabei legt sich die Dichtfläche von vorne her an die Ringdichtung an. Das Flanschteil wirkt sozusagen als Schwenkhebel, so dass die Dichtfläche den Hebelverhältnisses entsprechend stark gegen die Ringdichtung gedrückt wird und sich eine sichere Abdichtung ergibt.By obliquely plugging the flange is brought into the correct position, so that the position of use results after pivoting of the flange and the locking, so to speak by itself. The sealing surface is laid from the front to the ring seal. The flange part acts, so to speak, as a pivot lever, so that the sealing surface is pressed according to the lever ratio strongly against the ring seal and results in a secure seal.

Die vorliegende Erfindung soll sich ferner jeweils für sich auch auf die Adapterplatte und den Staubfilterbeutel mit Flanschteil für die erfindungsgemäße Vorrichtung erstrecken.The present invention is further intended to extend in each case also to the adapter plate and the dust filter bag with flange for the device according to the invention.

Zweckmäßige Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. Anspruch 20 bzw. 21 richtet sich auf die Adapterplatte als solche bzw. auf den Staubfilterbeutel mit Falschteil als solchen.Advantageous embodiments of the invention are specified in the subclaims.

Die aus der Zeichnung hervorgehende Vorrichtung dient zum lösbaren Befestigen eines Staubfilterbeutels 1 in einem nicht dargestellten staubsaugenden Gerät, das hierzu in üblicher Weise eine entsprechende Steckhalterung aufweist. Von dem Staubfilterbeutel 1 ist nur ein kleines Stück seiner Beutelwandung 2 gezeigt.The resulting from the drawing device is used for releasably securing a dust filter bag 1 in a vacuum cleaner, not shown, which has a corresponding plug-in holder in the usual way. Of the dust filter bag 1 only a small piece of its bag wall 2 is shown.

Die Beutelwandung 2 besteht aus luftdurchlässigem Material und enthält eine Eintrittsöffnung 3, durch die die ankommende Staubluft in das Beutelinnere 4 gelangt.The bag wall 2 consists of air-permeable material and contains an inlet opening 3, through which the incoming waste air passes into the bag interior 4.

An der Außenseite der Beutelwandung 2 ist ein Flanschteil 5 aus steifem Material, insbesondere Kunststoffmaterial, befestigt, das an die Beutelwandung 2 beispielsweise angeklebt oder mit dieser verschweißt ist. Das Flanschteil 5 weist eine mit der Eintrittsöffnung 3 fluchtende Durchtrittsöffnung 6 auf.On the outside of the bag wall 2, a flange 5 made of rigid material, in particular plastic material, attached, which is glued to the bag wall 2, for example, or welded thereto. The flange part 5 has a passage opening 6 aligned with the inlet opening 3.

Ferner ist eine ebenfalls aus steifem Material wie Kunststoffmaterial bestehende gerätespezifische Adapterplatte 7 vorgesehen, die einerseits am staubsaugenden Gerät festlegbar und andererseits mit dem Flanschteil 5 durch eine Steck- und Rastverbindung lösbar verbunden werden kann. Auf diese Weise wird der Filterbeutel 1 mit dem fest an ihm sitzenden Flanschteil 5 über die Adapterplatte 7 mit dem jeweiligen staubsaugenden Gerät - nachstehend nur noch Staubsauger genannt - verbunden.Furthermore, a device-specific adapter plate 7, which likewise consists of rigid material such as plastic material, is provided, which can be fixed on the one hand to the vacuuming device and on the other hand can be detachably connected to the flange 5 by a male and female connection. In this way, the filter bag 1 is connected to the seated at him flange 5 via the adapter plate 7 with the respective vacuum cleaner - hereinafter referred to only vacuum cleaner - connected.

Die auf dem Markt befindlichen Staubsauger weisen unterschiedliche Halterungen auf. Stellt man für diese unterschiedlichen Halterungen jeweils eine entsprechend angepasste Adapterplatte 7 zur Verfügung, wobei alle Adapterplatten an der anderen Seite gleich gestaltet sind, kann man für alle Staubsaugertypen den gleichen Staubsaugerbeutel verwenden, da ja das Flanschteil 5 mit jedem Adapterteil 7 unabhängig von dessen mit dem jeweiligen Staubsauger zu verbindenden Seite verbunden werden kann.The vacuum cleaners on the market have different brackets. If one makes a correspondingly adapted adapter plate 7 available for these different brackets, with all the adapter plates are the same design on the other side, you can use the same vacuum cleaner bag for all types of vacuum cleaner, since the flange 5 with each adapter part 7 regardless of the respective vacuum cleaner can be connected to the connecting side.

Das Adapterteil 7 kann dauerhaft im Staubsauger eingesetzt bleiben, so dass man bei einem Filterbeutelwechsel nur den Filterbeutel mit seinem Flanschteil 5 austauschen muss. Selbstverständlich kann man jedoch auch so vorgehen, dass man die Adapterplatte 7 zusammen mit dem Filterbeutel entnimmt und den Filterbeutel dann wechselt, wonach man den neuen Filterbeutel im mit der Adapterplatte 7 verbundenen Zustand wieder in den Staubsauger einsetzt.The adapter part 7 can remain permanently inserted in the vacuum cleaner, so that you only have to replace the filter bag with its flange 5 in a filter bag change. Of course, however, you can also proceed so that you take the adapter plate 7 together with the filter bag and the filter bag then changes, after which you put the new filter bag connected to the adapter plate 7 state again in the vacuum cleaner.

Eine der gängigen Halterungen in einem Staubsauger ist in Figur 4 strichpunktiert angedeutet. Sie wird von zwei geräteseitigen, im der Breite der Adapterplatte 7 entsprechenden Abstand zueinander angeordneten Führungsleisten 8 gebildet, hinter die die Adapterplatte 7 parallel zu ihrer Plattenebene in linearer Richtung 9 eingesteckt werden kann. Die beiden seitlichen Randbereich der Adapterplatte 7 bilden entsprechende, für das Einstecken geeignete Führungsstege 10.One of the common brackets in a vacuum cleaner is in FIG. 4 indicated by dash-dotted lines. It is formed by two device-side, in the width of the adapter plate 7 corresponding distance arranged guide bars 8, behind which the adapter plate 7 can be inserted parallel to its plate plane in the linear direction 9. The two lateral edge region of the adapter plate 7 form corresponding guide webs 10 suitable for insertion.

Die Adapterplatte 7 weist eine im mit dem Flanschteil 5 verbundenen Zustand mit dessen Durchtrittsöffnung 6 fluchtende Durchgangsöffnung 11 auf, die zusammen mit der Durchtrittsöffnung 6 eine Durchströmöffnung bildet, durch die hindurch der angesaugte Luftstrom in den Filterbeutel gelangt.The adapter plate 7 has a connected to the flange 5 with its passage opening 6 aligned through hole 11 which forms together with the passage opening 6 a flow-through, passes through the sucked air flow into the filter bag.

Geräteseitig ist üblicherweise noch ein Anschlussstutzen vorhanden, der bei eingesetzter Adapterplatte 7 in oder durch deren Durchgangsöffnung 11 ragt. In diesem Zusammenhang ist an der Adapterplatte 7 eine gelochte Dichtmembran 12 angeordnet, die einen in radialer Richtung in die Durchgangsöffnung 11 vorstehenden, ringförmig umlaufenden Dichtbereich 13 bildet, der bei in den Staubsauger eingesetzter Adapterplatte 7 den Anschlussstutzen umgreift und sich dichtend an den Anschlussstutzen anschmiegt. Dabei wird der ringförmige Dichtbereich 13 der Dichtmembran 12 beim Durchstecken des Anschlussstutzens etwas ausgestülpt.On the device side, a connecting piece is usually still present, which protrudes in inserted adapter plate 7 in or through the passage opening 11. In this context, a perforated sealing membrane 12 is arranged on the adapter plate 7, which forms a radially extending into the through hole 11 projecting annular sealing area 13 which engages with the vacuum cleaner inserted into the adapter plate 7, the connection piece and nestles sealingly against the connection piece. In this case, the annular sealing region 13 of the sealing membrane 12 is slightly everted during insertion of the connecting piece.

Ferner muss Vorsorge dafür getroffen werden, dass beim Betrieb des Staubsaugers an der Schnittstelle zwischen der Adapterplatte 7 und dem Flanschteil 5 kein Staub nach außen gelangen kann. Daher ist außerdem eine im verbundenen Zustand zwischen der Adapterplatte 7 und dem Flanschteil 5 wirksame Ringdichtung 14 zum Abdichten der Durchströmöffnung nach außen hin vorhanden.Furthermore, provision must be made that no dust can escape to the outside at the interface between the adapter plate 7 and the flange 5 during operation of the vacuum cleaner. Therefore, an effective in the connected state between the adapter plate 7 and the flange 5 ring seal 14 for sealing the flow opening to the outside is present.

Das Flanschteil 5 und die Adapterplatte 7 sind voneinander gesonderte Teile. Zum Herstellen der Verbindung zwischen dem Flanschteil 5 und der Adapterplatte 7 ist die Anordnung so getroffen, dass das Flanschteil 5 radial außerhalb der Ringdichtung 14 in von der Adapterplatte 7 weg geneigter Schrägstellung (siehe Figur 1) in Richtung gemäß Pfeil 15 an die Adapterplatte 7 ansteckbar und im angesteckten Zustand schwenkbar mit der Adapterplatte 7 verbunden ist, so dass das Flanschteil 5 in Richtung gemäß Pfeil 16 zur Adapterplatte 7 hin in eine koaxial zur Adapterplatte 7 angeordnete, mit der Adapterplatte 7 verrastete Gebrauchslage (Figuren 2 bis 7 und 8) verschwenkt werden kann. In der Gebrauchslage wird eine Dichtfläche 17 des Flanschteils 5 gegen die an der Adapterplatte 7 angeordnete Ringdichtung 14 gehalten, wie aus den Figuren 2 und 8 ersichtlich ist.The flange 5 and the adapter plate 7 are separate parts. For making the connection between the flange 5 and the adapter plate 7, the arrangement is such that the flange 5 radially outward of the ring seal 14 in inclined away from the adapter plate 7 inclined position (see FIG. 1 ) in the direction of arrow 15 to the adapter plate 7 attachable and pivotally connected in the infected state with the adapter plate 7, so that the Flange member 5 in the direction indicated by arrow 16 to the adapter plate 7 in a coaxial with the adapter plate 7 arranged, with the adapter plate 7 latched position of use ( FIGS. 2 to 7 and 8th ) can be pivoted. In the position of use, a sealing surface 17 of the flange 5 is held against the arranged on the adapter plate 7 ring seal 14, as shown in the Figures 2 and 8th is apparent.

Prinzipiell könnte auch umgekehrt die Ringdichtung am Flanschteil und die zugeordnete Dichtfläche an der Adapterplatte angeordnet sein.In principle, the ring seal on the flange part and the associated sealing surface on the adapter plate could conversely also be arranged.

Um das Flanschteil 5 in der Schrägstellung an die Adapterplatte 7 anstecken zu können, weist beim Ausführungsbeispiel der Figuren 1 bis 7 die Adapterplatte 7 eine von außen, beim Ausführungsbeispiel von vorne her zugängliche Steckaufnahme 18 auf, der ein am Flanschteil 5 angeordneter, vorstehender Steckvorsprung 19 zugeordnet ist, und zwar derart, dass der Steckvorsprung 19 entfernbar in die Steckaufnahme 18 einsteckbar ist. Der Steckvorsprung 19 weist an seinem Ende ein Schwenkachsteil 20 auf, das eine parallel zu einer Tangente der Durchgangsöffnung 11 verlaufende Schwenklagerachse zur schwenkbaren Lagerung des Flanschteils 5 bildet.In order to connect the flange 5 in the inclined position of the adapter plate 7, has in the embodiment of FIGS. 1 to 7 the adapter plate 7 a from the outside, in the embodiment accessible from the front plug receptacle 18, which is assigned to a flange 5, projecting plug projection 19, in such a way that the plug projection 19 is removably inserted into the receptacle 18. The plug projection 19 has at its end a Schwenkachsteil 20, which forms a parallel to a tangent of the through hole 11 extending pivot bearing axis for pivotally mounting the flange 5.

Die Steckaufnahme 18 und der Steckvorsprung 19 erstrecken sich der Richtung der sich damit ergebenden Schwenklagerachse entsprechend in Breitenrichtung (b). Dabei ist die Steckaufnahme 18 in einem entsprechenden Ansatz 21 der Adapterplatte 7 ausgebildet und der Steckvorsprung 19 an einem Ansatz 22 des Flanschteils 5 angeordnet, so dass sich der Steckvorsprung 19 in für den Benutzer bequemer Weise in die Steckaufnahme 18 einsetzen lässt. Das das Schwenkachsteil 20 bildende, im Schnitt kreisbogenförmige Ende 24 des Steckvorsprungs 19 gelangt nach seinem Einstecken und Absenken in Richtung gemäß Pfeil 15 in eine endseitige Lagerrinne 23 der Steckaufnahme 18, die die eigentliche Drehlagerstelle und dabei außerdem ein in axialer Richtung wirksames Widerlager bildet, an dem sich der Steckvorsprung 19 und somit das Flanschteil 5 beim Verschwenken des Flanschteils 5 in die Gebrauchslage abstützt, wenn die Dichtfläche 17 gegen die Ringdichtung 14 gedrückt wird. Dabei wird das Widerlager von einer die Steckausnehmung 18 an der der Adapterplatte 7 abgewandten Seite begrenzenden Stützpartie 40 am Ende des Steckvorsprungs 19 gebildet.The plug-in receptacle 18 and the plug-in projection 19 extend in the direction of the resultant pivot bearing axis in the width direction (b). In this case, the plug-in receptacle 18 is formed in a corresponding projection 21 of the adapter plate 7 and the plug-in projection 19 is arranged on a projection 22 of the flange 5, so that the plug-in projection 19 can be inserted into the plug-in receptacle 18 in a manner convenient for the user. The Schwenkachsteil 20 forming, in section circular arc-shaped end 24 of the male projection 19 passes after its insertion and lowering in the direction according to arrow 15 in an end-side mounting groove 23 of the plug receptacle 18, which forms the actual pivot bearing and also an effective in the axial direction abutment on which the plug projection 19 and thus the flange 5 is supported during pivoting of the flange 5 in the position of use, if the Sealing surface 17 is pressed against the ring seal 14. In this case, the abutment is formed by a plug-in recess 18 on the side facing away from the adapter plate 7 side supporting portion 40 at the end of the plug-in projection 19.

Während beim Ausführungsbeispiel nach den Figuren 1 bis 7 das Schwenkachsteil 20 am Flanschteil 5 und die zugeordnete Steckaufnahme 18 an der Adapterplatte 7 angeordnet ist, ist auch die umgekehrte Anordnung möglich, wie es beim Ausführungsbeispiel nach Figur 8 der Fall ist. Bei dieser Variante ist das Schwenkachsteil 20' an der Adapterplatte 7 und die Steckaufnahme 18' am Flanschteil 5 angeordnet.While in the embodiment according to the FIGS. 1 to 7 the Schwenkachsteil 20 on the flange 5 and the associated socket 18 is arranged on the adapter plate 7, the reverse arrangement is also possible, as in the embodiment according to FIG. 8 the case is. In this variant, the Schwenkachsteil 20 'on the adapter plate 7 and the plug-in receptacle 18' on the flange 5 is arranged.

Dabei wird das Schwenkachsteil 20' von einem dem Adapterteil 7 vorgelagerten Einhängestift 41 gebildet, der von vom Adapterteil 7 abstehenden Tragteilen 42 gehalten wird. Ferner wird die Steckaufnahme 18 in Gestalt einer Lagerrinne 23' von einer hakenartigen Einhängepartie 43 am Flanschteil 5 gebildet, die beim Anstecken des Flanschteils 5 an das Adapterteil 7 durch den Zwischenraum zwischen der den Dichtring 14 tragenden Partie des Adapterteils 7 und dem Schwenkachsteil 20' hindurch in axialer Richtung zwischen das Adapterteil 7 und das Schwenkachsteil 20' gelangt und am Schwenkachsteil 20' eingehängt wird. Die hakenartige Einhängepartie 43 hintergreift dann, wie dargestellt, das Schwenkachsteil 20' an der dem Adapterteil 7 zugewandten Seite. Das Schwenkachsteil 20' erstreckt sich parallel zu einer Tangente der Durchtrittsöffnung 6.In this case, the Schwenkachsteil 20 'is formed by a the adapter part 7 upstream Einhängestift 41, which is held by the adapter part 7 projecting support members 42. Further, the plug-in receptacle 18 is formed in the form of a bearing groove 23 'of a hook-like Abhängepartie 43 on the flange 5, when attaching the flange 5 to the adapter part 7 through the gap between the sealing ring 14 bearing portion of the adapter part 7 and the Schwenkachsteil 20' through in the axial direction between the adapter part 7 and the Schwenkachsteil 20 'passes and is mounted on Schwenkachsteil 20'. The hook-like hanging part 43 then engages, as shown, the Schwenkachsteil 20 'on the adapter part 7 side facing. The Schwenkachsteil 20 'extends parallel to a tangent of the passage opening. 6

Ansonsten kann das Ausführungsbeispiel nach Figur 8 der Ausführungsform nach den Figuren 1 bis 7 entsprechen.Otherwise, the embodiment according to FIG. 8 the embodiment of the FIGS. 1 to 7 correspond.

Bei beiden Ausführungsformen können anstelle eines durchgehenden Längsachsteils 20, 20', mehrere, insbesondere zwei, in ihrer axialen Richtung mit Abstand zueinander angeordnete Längsachsteile vorgesehen sein. Dementsprechend kann auch die Steckaufnahme 18, 18' in mehrere mit Abstand zueinander angeordnete Steckaufnahmen unterteilt sein.In both embodiments, instead of a continuous Längsachsteils 20, 20 ', a plurality, in particular two, be provided in their axial direction with spaced-apart Längsachsteile. Accordingly, the plug-in receptacle 18, 18 'may be divided into a plurality of spaced-apart plug-in receptacles.

Das Verrasten des Flanschteils 5 mit der Adapterplatte 7 erfolgt radial außerhalb der Ringdichtung 14. Die Ringdichtung 14 befindet sich also in der Gebrauchslage des Flanschteils 5 zwischen der Schwenklagerung und der Verrastungsstelle des Flanschteils 5, so dass ein sicheres und somit dichtes Andrücken der Dichtfläche 17 an die Ringdichtung 14 bewirkt wird.The locking of the flange 5 with the adapter plate 7 takes place radially outside the ring seal 14. The ring seal 14 is thus in the position of use of the flange 5 between the pivot bearing and the Verrastungsstelle the flange 5, so that a secure and thus tight pressing the sealing surface 17 at the ring seal 14 is effected.

Beim Entnehmen des Filterbeutels 1 wird umgekehrt zuerst die Verrastung mit der Adapterplatte 7 gelöst, wonach man das Flanschteil 5 entgegen Pfeil 16 verschwenkt und dann aus seiner in die Steckaufnahme 18, 18' eingehängten Lage herauszieht.When removing the filter bag 1, conversely, first the latching with the adapter plate 7 is released, after which the flange part 5 is pivoted against arrow 16 and then pulled out of its in the socket 18, 18 'hinged position.

Zum Verrasten ist an der Adapterplatte 7 ein Rastglied 25 bewegbar angeordnet, das in der Gebrauchslage einen am Flanschteil 5 angeordneten Rastvorsprung 26 verrastend hintergreift. Dabei sind das Rastglied 25 und der Rastvorsprung 26 mit Bezug auf die von der Durchtrittsöffnung 6 und der Durchgangsöffnung 11 gebildete Durchströmöffnung entgegengesetzt zur Steckaufnahme 18, 18' und zum Schwenkachsteil 20, 20' angeordnet.For locking a latching member 25 is movably arranged on the adapter plate 7, which engages latching in the position of use a arranged on the flange 5 locking projection 26. In this case, the latching member 25 and the latching projection 26 are arranged opposite to the plug-in receptacle 18, 18 'and the Schwenkachsteil 20, 20' with respect to the passage formed by the passage opening 6 and the through-hole 11.

Die Verrastung des Flanschteils 5 erfolgt beim Verschwenken des Flanschteils in die Gebrauchslage selbsttätig, indem der Rastvorsprung 26 gegen das Rastglied 25 läuft und dieses entgegen einer Rückstellkraft auslenkt, wonach das Rastglied 25 hinter dem Rastvorsprung 26 unter der Wirkung der Rückstellkraft zurückschnappt und die Verrastung bewirkt.The latching of the flange 5 takes place automatically when pivoting the flange in the position of use by the Locking projection 26 runs against the locking member 25 and this deflects against a restoring force, after which the locking member 25 snaps back behind the locking projection 26 under the action of the restoring force and causes the locking.

Es wird darauf hingewiesen, dass das Rastglied prinzipiell auch am Flanschteil und der Rastvorsprung an der Adapterplatte angeordnet sein könnte.It should be noted that the locking member could in principle also be arranged on the flange part and the latching projection on the adapter plate.

In jedem Falle ist zweckmäßigerweise vorgesehen, dass das Rastglied 25 an einem um eine Schwenkachse 27 schwenkbaren Schwenkteil 28 ausgebildet ist, das im dargestellten Falle an der Adapterplatte 7 gelagert ist. Dabei ist das Schwenkteil 28 durch eine Federkraft in Richtung auf die aus Figur 2 hervorgehende Verrastungsposition hin belastet. Diese Federkraft greift einerseits am Schwenkteil 28 an und stützt sich andererseits an der Adapterplatte 7 ab. Die Federkraft kann beispielsweise von einer parallel zur axialen Richtung der Durchgangsöffnung 11 gerichteten Schraubenfeder 29 aufgebracht werden. Hierzu weist das Schwenkteil 28 eine parallel zur Adapterplatte 7 abstehende Abstützpartie 30 auf, die in eine vom Umfang der Adapterplatte 7 her in diese eingeformte Ausnehmung 31 eingreift, in der die Schraubenfeder 29 untergebracht ist.In any case, it is expediently provided that the locking member 25 is formed on a pivotable about a pivot axis 27 pivot member 28 which is mounted on the adapter plate 7 in the illustrated case. In this case, the pivot member 28 by a spring force in the direction of the FIG. 2 resulting latching position burdened. This spring force engages on the one hand on the pivot member 28 and on the other hand is supported on the adapter plate 7 from. The spring force can be applied, for example, by a helical spring 29 directed parallel to the axial direction of the passage opening 11. For this purpose, the pivot member 28 has a parallel to the adapter plate 7 projecting support section 30 which engages in a molded-in from the periphery of the adapter plate 7 in this recess 31, in which the coil spring 29 is housed.

Wie erwähnt, läuft das Verrasten selbsttätig ab. Um zur Wegnahme des Filterbeutels 1 die Verrastung zu lösen, ist das Rastglied 25 mit einer griffartigen Handhabe 32 verbunden, die Bestandteil des Schwenkteils 28 ist. Drückt man von vorne her gegen die als hochstehendes Plättchen ausgebildete Handhabe 32, wird auf das Schwenkteil 28 entgegen der Federkraft ein die Verrastung lösendes Schwenkmoment ausgeübt.As mentioned, the latching runs automatically. In order to release the catch to remove the filter bag 1, the locking member 25 is connected to a handle-like handle 32, which is part of the pivoting member 28. If you push from the front against the designed as a raised platelet handle 32, a latching torque releasing the lock is applied to the pivot member 28 against the spring force.

Das Rastglied 25 und der Rastvorsprung 26 weisen eine parallel zur Schwenklagerachse 20 verlaufende Längsgestalt auf, so dass die Verrastung in Breitenrichtung b über eine möglichst große Länge hinweg erfolgt. Dies begünstigt das sichere Andrücken der Dichtfläche 17 gegen die Ringdichtung 14.The latching member 25 and the latching projection 26 have a parallel to the pivot bearing axis 20 extending longitudinal shape, so that the latching takes place in the width direction b over a maximum possible length. This favors the secure pressing of the sealing surface 17 against the ring seal fourteenth

Die entgegengesetzte Steckaufnahme 18, 18' und das zugehörige Schwenkachsteil 20, 20' können entsprechend lang sein, sieht man von der oben erwähnten eventuellen Unterteilung ab.The opposite plug-in receptacle 18, 18 'and the associated Schwenkach part 20, 20' may be correspondingly long, apart from the above-mentioned eventual subdivision.

Der Rastvorsprung 26 kann an einem abstehenden Ansatz 33 des Flanschteils angeordnet sein.The latching projection 26 may be arranged on a protruding projection 33 of the flange.

Die dargestellte Adapterplatte 7 kann, wie bereits erwähnt, von außerhalb des Staubsaugers in linearer Richtung parallel zu ihrer Plattenebene in die geräteseitige Steckhalterung eingesteckt werden. In diesem Zusammenhang ist zweckmäßigerweise vorgesehen, dass das Flanschteil 5 an den in Einsteckrichtung vorne liegenden Bereich der Adapterplatte 7 ansteckbar ist, wie es beim Ausführungsbeispiel vorgesehen ist. Dies erleichtert die Handhabung durch den Verbraucher.The adapter plate 7 shown can, as already mentioned, be plugged from outside the vacuum cleaner in a linear direction parallel to its plane in the device-side plug-in bracket. In this context, it is expediently provided that the flange part 5 can be attached to the region of the adapter plate 7 which lies in the insertion direction in the insertion direction, as is provided in the exemplary embodiment. This facilitates handling by the consumer.

Die Ringdichtung 14 wird zweckmäßigerweise von einem Ringkörper mit kreisförmigem Querschnitt, das heißt von einem sogenannten O-Ring, gebildet, gegen den sich das Flanschteil 5 legt. Aufgrund der vom Flanschteil 5 in der Gebrauchslage auf den O-Ring ausgeübten Kraft verformt sich dieser elastisch etwas und schmiegt sich gut an die Dichtfläche 17 an.The ring seal 14 is expediently formed by an annular body with a circular cross-section, that is to say by a so-called O-ring, against which the flange part 5 lies. Due to the force exerted by the flange 5 in the position of use on the O-ring force this deforms elastically something and nestles well on the sealing surface 17 at.

Eine weitere zweckmäßige Maßnahme besteht darin, dass die Dichtfläche 17 konusartige Gestalt aufweist. Auf diesen Weise kann sie in der Gebrauchslage konisch in die von dem O-Ring gebildete Ringdichtung 14 eingreifen (Figuren 1 bis 7)oder die Ringdichtung 14 konisch umgreifen (Figur 8). Hierdurch wird die Dichtfläche 17 und mit dieser das Flanschteil 5 mit Bezug auf die Ringdichtung 14 und somit mit Bezug auf die Adapterplatte 7 zentriert.Another expedient measure is that the sealing surface 17 has a conical shape. In this way, it can conically engage in the position of use in the ring seal 14 formed by the O-ring ( FIGS. 1 to 7 ) or surround the ring seal 14 conically ( FIG. 8 ). hereby the sealing surface 17 and with this the flange part 5 with respect to the ring seal 14 and thus with respect to the adapter plate 7 is centered.

Aus der Zeichnung geht ferner hervor, dass die Adapterplatte 7 von einer am Staubsauger festzulegenden Plattenpartie 34 und einer von der Plattenpartie 34 halsartig abstehenden, mit dem Flanschteil 5 verbindbaren Anschlusspartie 35 gebildet wird. Die Steckaufnahme 18 beim Ausführungsbeispiel der Figuren 1 bis 7 bzw. das Schwenkachsteil 20' beim Ausführungsbeispiel nach Figur 8, die Ringdichtung 14 und das Rastglied 25 sind an der Anschlusspartie 35 angeordnet. Aufgrund dieser Zweiteilung der Adapterplatte 7 kann die stets gleichbleibende Anschlusspartie 35 mit an unterschiedliche Gerätehalterungen angepassten Plattenpartien 34 kombiniert werden. Die Plattenpartie 34 und die Anschlusspartie 35 sind in geeigneter Weise fest miteinander verbunden, so beispielsweise miteinander verschraubt oder verschweißt. Dies kann, wie aus den Figuren 1, 2 und 8 hervorgeht, unter Zwischenfügen des äußeren Randbereichs der Dichtmembran 12 erfolgen, so dass diese fest an Ort und Stelle gehalten wird.It is also apparent from the drawing that the adapter plate 7 is formed by a plate section 34 to be fixed to the vacuum cleaner and a neck portion projecting from the plate section 34 and connectable to the flange section 5. The plug-in receptacle 18 in the embodiment of FIGS. 1 to 7 or the Schwenkachsteil 20 'in the embodiment according to FIG. 8 , the ring seal 14 and the locking member 25 are arranged on the connecting part 35. Due to this division of the adapter plate 7, the always constant connection part 35 can be combined with adapted to different device holders plate sections 34. The plate section 34 and the connection part 35 are suitably firmly connected to each other, for example screwed together or welded. This can, as from the FIGS. 1 . 2 and 8th shows, carried out with the interposition of the outer edge region of the sealing membrane 12, so that it is held firmly in place.

Das Flanschteil 5 kann eine im Wesentlichen ringförmige Gestalt aufweisen. Die beiden Ansätze 32 und 33 stehen in radialer Richtung ab.The flange part 5 may have a substantially annular shape. The two approaches 32 and 33 are in the radial direction.

Schließlich geht aus der Zeichnung noch hervor, dass an der Rückseite der Adapterplatte 7 sowie an der Betätigungsfläche der Handhabe 32 die Griffigkeit erhöhende noppenartige Vorsprünge 36 vorhanden sein können.Finally, it is apparent from the drawing that on the back of the adapter plate 7 and on the actuating surface of the handle 32, the grip-increasing knob-like projections 36 may be present.
