Description

Die Erfindung betrifft einen Filter gemäß dem Oberbegriff des ersten Anspruchs.The invention relates to a filter according to the preamble of the first claim.

Bei einem bekannten Filter dieser Art (FR-A-1 119 758) ist am Filterbeutel eine Versteifungsplatte mit einer Einlaßöffnung festgesetzt. Auf der Versteifungsplatte befinden sich parallele Führungsleisten, zwischen welchen eine aus knicksteifem Material gefertigte Lasche verschiebbar geführt ist. Diese Lasche ist mit einem Durchbruch ausgestattet, welcher vor und während der Benutzung des Filterbeutels in einer Flucht mit der Einlaßöffnung liegt. Ein freiliegender Randbereich der Lasche ist mit einer kleinen Bohrung versehen. Die Versteifungsplatte wird dabei so durch die Öffnungsebene des zugehörigen Staubbeutelraumes in dort angeordnete Führungsschienen eingeschoben, daß zuerst dieser Randbereich der Lasche eintaucht. Bei vollkommen in die Führungsschienen eingeschobener Versteifungsplatte schnappt ein gehäusefester Federhaken in die Bohrung ein. Wird danach der Filterbeutel an der Versteifungsplatte, die auch eine die Lasche übergreifende Abdecklage aufweist, aus den Führungsschienen herausgezogen, dann hält der Federhaken die Lasche fest, wodurch ein undurchbrochener Abschnitt der Lasche vor die Einlaßöffnung der Versteifungsplatte gestellt wird und ein Staubaustritt unterbunden ist. Durch weiteres Ziehen an der Versteifungsplatte reißt dann die Lasche im Bereich der Bohrung und des Federhakens auf, wonach der Filterbeutel für seine endgültige Entfernung aus den Führungsschienen freigegeben ist. Von Nachteil ist bei dieser Anordnung, daß bei einer Bewegung der Versteifungsplatte auch der daran angeordnete Filterbeutel bewegt wird, wodurch sich eine Volumenänderung ergibt, die ein Ausblasen von staubbeladener Luft nach sich ziehen kann.In a known filter of this type (FR-A-1 119 758), a stiffening plate with an inlet opening is attached to the filter bag. There are parallel guide strips on the stiffening plate, between which a tab made of buckling-resistant material is slidably guided. This tab is equipped with an opening which is in alignment with the inlet opening before and during use of the filter bag. An exposed edge area of the tab is provided with a small hole. The stiffening plate is inserted through the opening level of the associated dust bag space into guide rails arranged there so that this edge area of the tab first immerses. When the stiffening plate is fully inserted into the guide rails, a spring hook fixed to the housing snaps into the hole. If the filter bag on the stiffening plate, which also has a cover layer overlapping the tab, is then pulled out of the guide rails, the spring hook holds the tab, whereby an unbroken section of the tab is placed in front of the inlet opening of the stiffening plate and dust escape is prevented. By further pulling on the stiffening plate the tears Tab in the area of the bore and the spring hook, after which the filter bag is released for its final removal from the guide rails. The disadvantage of this arrangement is that when the stiffening plate is moved, the filter bag arranged thereon is also moved, which results in a change in volume which can result in the blowing out of dust-laden air.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Filter gemäß dem Oberbegriff des Anspruchs 1 Maßnahmen zu treffen, die ein Schließen der Einlaßöffnung des Filterbeutels vor einer Betätigung der Versteifungsplatte auf ein einfache Weise ermöglichen.The invention has for its object to take measures in a filter according to the preamble of claim 1, which allow a closing of the inlet opening of the filter bag before actuation of the stiffening plate in a simple manner.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des ersten Anspruchs.This object is achieved according to the invention by the characterizing features of the first claim.

Bei einer Ausgestaltung eines Filters gemäß der Erfindung wird bei einem Entfernen des Filterbeutels aus dem Staubsammelraum zuerst die Handhabe der Lasche erfaßt und durch Ziehen soweit verschoben, daß die Einlaßöffnung verschlossen ist. Dabei wirkt einem gleichzeitigen Bewegen der Versteifungsplatte zumindest die Reibung derselben in ihren Führungsschienen entgegen. Die Reibung zwischen den Führungsleisten für die Lasche und der Lasche selbst kann dabei aufgrund ihrer knicksteifen Ausführung sehr gering gehalten werden.In one embodiment of a filter according to the invention, when the filter bag is removed from the dust collection space, the handle of the tab is first grasped and moved so far by pulling that the inlet opening is closed. A simultaneous movement of the stiffening plate counteracts at least the friction of the same in its guide rails. The friction between the guide strips for the bracket and the bracket itself can be kept very low due to its rigid construction.

Auch beim Einsetzen des Filters ergeben sich Vorteile, weil dann die Versteifungsplatte über die Handhabe der Lasche in ihre Führungsschienen eingeschoben wird. Dabei ensteht durch Reibung und insbesondere bei vollkommen eingeschobener Versteifungsplatte eine Kraftkomponente, welche die Lasche zur Einlaßöffnung hin verschiebt, selbst wenn die Lasche vorher herausgezogen war. Es ist somit nicht nur ein willkürliches Schließen oder Öffnen der Einlaßöffnung möglich, vielmehr tritt das Schließen bzw. Öffnen bei der Anwendung in einem Staubsauger funktionsrichtig selbsttätig ein, weil die Verschieberichtung der Lasche mit der Einschiebrichtung der Versteifungsplatte in die zugeordnete Halterung bzw. in die Führungschienen übereinstimmt. Dabei wird immer zuerst die Lasche betätigt, bevor der Filter bewegt wird.There are also advantages when inserting the filter because the stiffening plate is then pushed into its guide rails via the handle of the tab. This creates a force component due to friction and especially when the stiffening plate is fully inserted, which moves the tab towards the inlet opening, even if the tab was previously pulled out. It is therefore not just an arbitrary closing or opening of the Inlet opening possible, rather closing or opening occurs automatically when used in a vacuum cleaner, because the direction of displacement of the tab corresponds to the direction of insertion of the stiffening plate into the associated holder or into the guide rails. The tab is always pressed first before the filter is moved.

Darüber hinaus kann die Anordnung des Filters im Staubsauger auch so erfolgen, daß die Handhabe der Lasche in den Schließweg des den Staubbeutelraum abschließenden Deckels steht, wenn die Versteifungsplatte oder die Lasche nicht in ihre funktionsgerechte Lage im Staubbeutelraum gebracht sind. Der Deckel kann dann entweder nicht geschlossen werden bzw. drückt er die Lasche in ihre Offenstellung.In addition, the arrangement of the filter in the vacuum cleaner can also be carried out so that the handle of the tab is in the closing path of the cover closing the dust bag compartment if the stiffening plate or the tab are not brought into their functional position in the dust bag compartment. The lid can then either not be closed or it presses the tab into its open position.

Die Erfindung ist nachfolgend anhand der Skizzen eines Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with the aid of the sketches of an exemplary embodiment.

Ein Filter für Staubsauger weist einen vorzugsweise aus Papier gefertigten Filterbeutel 1 auf, der an seiner Anschlußseite eine Versteifungsplatte 2 mit einer Einlaßöffnung 3 trägt. Die Versteifungsplatte 2 besitzt an zwei gegenüberliegenden parallelen Rändern Führungsleisten 4 für eine dazwischen angeordnete, darin verschiebbar gelagerte Lasche 5. In der Lasche 5 befindet sich ein Durchbruch 6, der bei weitgehend in die Führungsleisten 4 eingeschobener Lasche 5 in einer Flucht mit der Einlaßöffnung 3 liegt (Figur 1). Die Lasche 5 ist mit einer Handhabe 7 versehen, die an einen quer zu der durch einen Doppelpfeil 8 angedeuteten Verschieberichtung der Lasche 5 verlaufenden Randbereich 9 angeformt ist. Die Handhabe 7 ragt dabei über den benachbarten oberen Rand 10 der Versteifungsplatte hinaus. Sie kann jedoch auch auf die Fläche der Lasche aufgesetzt sein. Zwischen dem Durchbruch 6 und dem unteren, der Handhabe 7 abgewandten Rand 11 der Lasche 5 ist ein undurchbrochener Abschnitt ausgebildet, der nach einem Verschieben der Lasche 5 nach oben gemäß Figur 2 zumindest die Einlaßöffnung 3 dicht überdeckt. Dabei ist die Lasche 5 knicksteif ausgebildet, um sie beliebig zwischen der eingeschobenen Stellung gemäß Figur 1 in welcher der Durchbruch 6 mit der Einlaßöffnung fluchtet, und der ausgezogenen Stellung gemäß Figur 2, in welcher die Einlaßöffnung durch den undurchbrochenen Abschnitt verschlossen ist, bewegen zu können. Durch die Steifigkeit wird auch der bleibende Verschluß der Einlaßöffnung gemäß Figur 2 sichergestellt, obwohl die Führungsleisten 4 nur benachbarte Randteile 12 der Lasche übergreifen. Außerdem kann der Filter selbst bei gefülltem Staubbeutel 1 an der Handhabe 7 transportiert werden, ohne den dichten Verschluß der Einlaßöffnung 3 zu beeinträchtigen.A filter for vacuum cleaners preferably has a paper manufactured filter bag 1, which carries on its connection side a stiffening plate 2 with an inlet opening 3. The stiffening plate 2 has at two opposite parallel edges guide strips 4 for an interposed, displaceably mounted tab 5. In the tab 5 there is an opening 6, which is in alignment with the guide plate 4 inserted tab 5 in alignment with the inlet opening 3 (Figure 1). The tab 5 is provided with a handle 7, which is formed on an edge region 9 which extends transversely to the direction of displacement of the tab 5 indicated by a double arrow 8. The handle 7 protrudes beyond the adjacent upper edge 10 of the stiffening plate. However, it can also be placed on the surface of the tab. Between the opening 6 and the lower edge 11 of the tab 5 facing away from the handle 7, an unbroken section is formed which, after the tab 5 has been moved upward, at least tightly covers the inlet opening 3 according to FIG. The tab 5 is designed to be kink-resistant in order to be able to move it arbitrarily between the inserted position according to FIG. 1 in which the opening 6 is aligned with the inlet opening, and the extended position according to FIG. 2 in which the inlet opening is closed by the unbroken section . The rigidity also ensures the permanent closure of the inlet opening according to FIG. 2, although the guide strips 4 only overlap adjacent edge parts 12 of the tab. In addition, the filter can be transported on the handle 7 even when the dust bag 1 is full, without impairing the tight closure of the inlet opening 3.

An den mit den Führungsleisten 4 zusammenwirkenden Randteilen 12 weist die Lasche 5 Anschläge 13 bzw. 14 auf, von welchen die der Handhabe 7 benachbarten Anschläge 13 mit den Enden der Führungsleisten 4 in Anlage treten, die der oberen Kante 10 der Versteifungsplatte 2 benachbart sind. Diese Anschläge 13 treten gemäß Figur 1 mit den oberen Enden 15 der Führungsleisten (4) in Eingriff, wenn die Lasche 5 eingeschoben ist. Dagegen ist an die Führungsleisten 4 an deren Längskanten je ein Gegenanschlag 16 angeformt, die zur Mitte der Versteifungsplatte 2 ragen. Die zugehörigen Anschläge 14 an der Lasche 5 sind durch aus der Ebene der Lasche 5 herausgebogene Randabschnitte 17 gebildet, die beispielsweise durch Auftragen von aushärtendem Lack oder Kleber versteift sind. Die Anschläge 14 treten gemäß Figur 2 bei ausgezogener Stellung der Lasche 5 in Anlage mit den Gegenanschlägen 16 und begrenzen die Auszugbewegung so, daß der undurchbrochene Abschnitt die Einlaßöffnung 3 überdeckt.On the edge parts 12 which cooperate with the guide strips 4, the tab 5 has stops 13 and 14, of which the stops 13 adjacent to the handle 7 come into contact with the ends of the guide strips 4 which are adjacent to the upper edge 10 of the stiffening plate 2. According to FIG. 1, these stops 13 engage the upper ends 15 of the guide strips (4) when the tab 5 is inserted. In contrast, a counter stop 16 is formed on each of the longitudinal edges of the guide strips 4, which protrude toward the center of the stiffening plate 2. The associated stops 14 on the tab 5 are through from the Level of the tab 5 bent out edge portions 17 are formed, which are stiffened, for example, by applying hardening lacquer or adhesive. According to FIG. 2, the stops 14 come into contact with the counter stops 16 when the tab 5 is in the extended position and limit the pull-out movement in such a way that the unbroken section covers the inlet opening 3.

Die Führungsleisten 4 können als eigenständige Bauteile auf der Frontseite der Versteifungsplatte 2 festgesetzt sein. Gemäß Figur 3 sind sie jedoch einstückig damit verbunden. Hierzu sind an die entsprechenden Ränder der Versteifungsplatte 2 je ein Zwischenstreifen 18 und daran ein oberer Streifen 19 angesetzt, die über Knicklinien 20 aneinander hängen. Dabei ist der Gegenanschlag 16 gemäß der Abwicklung nach Figur 3 aus dem Zwischenstreifen 18 freigeschnitten und bildet gleichzeitig eine Führungsleiste. Durch Hochklappen der Zwischenstreifen und gegenläufiges Abknicken der oberen Streifen 19 (Figur 4) und weiteres Falten nach Art einer Ziehharmonika kommen die oberen Streifen 19 so zu liegen, daß die mit den Gegenanschlägen 16 versehenen freigestanzten Fahnen aufeinander zuweisen. Dabei bewirkt der unter dem oberen Streifen 19 liegende Zwischenstreifen 18 die Abstandshalterung der Fahnen 21 gegenüber der Ebene der Versteifungsplatte 2, so daß die Lasche 5 in die so gebildeten Führungen eingeschoben werden kann. Soll die Lasche 5 über einen längeren Bereich geführt werden, kann ein dritter Streifen vorgesehen werden, der breiter als die anderen Streifen ist, so daß dessen freier Rand über die nach innen gefaltete Knicklinie der vorherigen Streifen 18,19 hinausragt. An diesen Rand werden dann zweckmäßig die Gegenanschläge 16 angeformt. Die Figuren 5 und 6 zeigen die fertig geformte Versteifungsplatte 2 mit den Führungen 4 für die Lasche 5.The guide strips 4 can be fixed as independent components on the front of the stiffening plate 2. According to Figure 3, however, they are integrally connected to it. For this purpose, an intermediate strip 18 and an upper strip 19 are attached to the corresponding edges of the stiffening plate 2, which are attached to one another via folding lines 20. The counter-stop 16 is cut out of the intermediate strip 18 according to the development according to FIG. 3 and at the same time forms a guide strip. By folding up the intermediate strips and bending the upper strips 19 in the opposite direction (FIG. 4) and further folding in the manner of an accordion, the upper strips 19 come to lie so that the freely stamped flags provided with the counter-stops 16 point towards one another. The intermediate strip 18 located under the upper strip 19 causes the spacing of the flags 21 with respect to the plane of the stiffening plate 2, so that the tab 5 can be inserted into the guides thus formed. If the tab 5 is to be guided over a longer area, a third strip can be provided which is wider than the other strips, so that its free edge projects beyond the inwardly folded crease line of the previous strips 18, 19. The counter stops 16 are then expediently formed on this edge. FIGS. 5 and 6 show the finished stiffening plate 2 with the guides 4 for the bracket 5.

Die Figuren 7 bis 9 zeigen die Lasche 5 mit dem Durchbruch 6 und den Anschlägen 13 und 14. Dabei sind die Anschläge 14 gemäß den Figuren 8 und 9 durch Freischneiden eines Randabschnittes 17 der Lasche 5 gebildet, wobei die Randabschnitte 17 mit Abstand zur Mitte hin gegenüber den Randteilen 12 versetzt sind. Die freigeschnittenen Randabschnitte 17 werden um 90o abgewinkelt und stehen so aus der Ebene der Lasche 5 hervor und stoßen daher bei entsprechendem Auszug der Lasche 5 gegen die Gegenanschläge 16. Wenn die Lasche 5 aus Papiermaterial oder dergleichen besteht, wird zur Vermeidung des Rückfaltens auf die Randabschnitte 17 und die benachbarten Zonen aushärtender Lack oder Kleber aufgetragen, welche die Anschläge 14 in ihrer aufgestellten Lage fixieren. Vorzugsweise ist die Lasche 5 im Bereich ihrer der Handhabe 7 abgewandten Seitenkante 11 auch bei eingeschobener Lasche 5 kürzer als die Versteifungsplatte 2, wodurch bei der Anwendung dieses Filters in einem Staubsauger insbesondere das automatische Verschließen beim Ausheben des Filters sichergestellt wird.FIGS. 7 to 9 show the tab 5 with the opening 6 and the stops 13 and 14. The stops 14 according to FIGS. 8 and 9 are formed by cutting out an edge section 17 of the tab 5, the edge sections 17 being at a distance from the center are offset from the edge parts 12. The cut out Edge portions 17 are o angled at 90 and are thus out of the plane of the flap 5 projecting and therefore abut on the corresponding excerpt of the tab 5 16 against the counter-stops, when the tab 5 is made of paper material or the like is to prevent the folding back the edge portions 17 and the adjacent zones of hardening lacquer or adhesive are applied, which fix the stops 14 in their erected position. Preferably, the tab 5 in the region of its side edge 11 facing away from the handle 7 is shorter than the stiffening plate 2 even when the tab 5 is pushed in, as a result of which, when this filter is used in a vacuum cleaner, in particular the automatic closing when the filter is lifted out is ensured.

Der vorbeschriebenen Filter kann an sich bei jedem Staubsauger mit geeigneter Halterung für die Versteifungsplatte angewandt werden. Von besonderem Vorteil ist es jedoch, wenn bei einem Staubsauger 25, wie er in den Figuren 10 bis 12 im Bereich einer Halterung 26, die in einem Staubbeutelraum 27 angeordnet ist, die Versteifungsplatte so angeordnet wird, daß die Handhabe 7 der Lasche 5 bis an die Innenseite eines den Staubbeutelraum 7 verschließenden Deckels 28 reicht. Die Halterung 26 besteht dabei aus parallelen, U-förmigen Führungsschienen 26, in welche die Versteifungsplatte 2 mit ihren Führungsleisten 4 durch die Öffnungsebene des Staubbeutelraumes 27 bei geöffnetem Deckel 28 von oben eingesetzt wird. Zwischen den Führungsschienen 26 mündet in den Staubbeutelraum 27 ein Einlaßstutzen 29, durch den staubbeladene Luft in den Filterbeutel 1 gefördert wird. Dabei greift das insbesondere aus gummielastischem Material bestehende Endstück 30 des Einlaßstutzens 29 bei gemäß Figru 10 funktionsgerecht eingesetzter Versteifungsplatte 2 durch den Druchbruch 6 in die Einlaßöffnung 3 hinein. Das Endstück 30 verjüngt sich zur Versteifungsplatte 2 hin kegelig, um den Eingriff in die Einlaßöffnung 3 zu erleichtern. Zur besseren Abdichtung des Spalts zwischen dem Rand der Einlaßöffnung 3 und dem Kegelmantel des Endstücks 30 ist auf der Versteifungsplatte 2 noch eine Ringdichtung 31 vorgesehen, die einen äußeren Ringabschnitt der Einlaßöffnung umgreift und die vom Endstück 30 in das innere Filterbeutels ausgelenkt wird, um einen dichten Abschluß zu erreichen.The filter described above can be used with any vacuum cleaner with a suitable holder for the stiffening plate. It is of particular advantage, however, if in a vacuum cleaner 25, as shown in FIGS. 10 to 12 in the area of a holder 26, which is arranged in a dust bag space 27, the stiffening plate is arranged such that the handle 7 of the tab 5 to the inside of a cover 28 closing the dust bag space 7 is sufficient. The bracket 26 consists of parallel, U-shaped guide rails 26 into which the stiffening plate 2 with its guide strips 4 is inserted from above through the opening plane of the dust bag space 27 with the cover 28 open. Between the guide rails 26, an inlet connection 29 opens into the dust bag space 27, through which dust-laden air is conveyed into the filter bag 1. In this case, the end piece 30 of the inlet connector 29, which is made in particular of rubber-elastic material, engages through the opening 6 into the inlet opening 3 when the reinforcing plate 2 is used in accordance with FIG. The end piece 30 tapers conically towards the stiffening plate 2 in order to facilitate the engagement in the inlet opening 3. For better sealing of the gap between the edge of the inlet opening 3 and the conical jacket of the end piece 30, an annular seal 31 is also provided on the stiffening plate 2, which surrounds an outer ring portion of the inlet opening and which is deflected by the end piece 30 into the inner filter bag to provide a tight seal To achieve completion.

Ist hierbei der Filterbeutel 1 gefüllt, dann wird von Hand die Handhabe 7 erfaßt und der gesamte Filter bei geöffnetem Deckel 7 nach oben herausgehoben. Dabei wird die Zugkraft über die Handhabe 7 auf die Lasche 5 ausgeübt, die aufgrund der Schräge des Endstücks 30 zusammen mit der Versteifungsplatte 2 zum Filterbeutel 1 hin ausgewölbt wird und unter elastischer Spannung steht. Beim weiteren Ziehen der Handhabe 7 kann dann entweder die Lasche 4 zunächst allein nach oben gleiten, bis ihre Anschläge 14 mit den Gegenanschlägen 16 in Eingriff gelangen. Dann ist die Einlaßöffnung 3 durch den undurchbrochenen Abschnitt der Lasche 5 verschlossen, so daß bereits dann die angestrebte selbsttätige Verschlußfunktion erfüllt ist.If the filter bag 1 is filled, the handle 7 is gripped by hand and the entire filter is lifted upwards with the lid 7 open. The tensile force is exerted via the handle 7 on the tab 5, which due to the bevel of the end piece 30 together with the stiffening plate 2 bulges toward the filter bag 1 and is under elastic tension. When pulling the handle 7 further, either the tab 4 can initially slide upwards alone until its stops 14 come into engagement with the counter-stops 16. Then the inlet opening 3 is closed by the unbroken portion of the tab 5, so that the desired automatic closure function is then already fulfilled.

Wird beim Hochziehen der Lasche 7 dagegen auch die Versteifungsplatte 2 trotz des Gewichts des Filterbeutels 1 mit nach oben gezogen, dann erfolgt die selbsttätige Verschiebung der Lasche 5 gegenüber der Versteifungsplatte 2 dann, wenn beide außer Eingriff mit dem Endstück 30 gelangen, nachdem dann das Gewicht des Filterbeutels 1 die Versteifungsplatte 2 gegen die Zugkraft an der Handhabe 7 nach unten bewegt und der undurchbrochene Abschnitt der Lasche 5 in Überdeckung mit der Einlaßöffnung 3 kommt. Ist in diesem Falle der untere Rand 11 der Lasche 5 kürzer als die Versteifungsplatte 2, dann kommt das gummielastische Endstück mit seiner erhöhten Reibungskraft auf jeden Fall dann allein mit der Versteifungsplatte 2 in Eingriff, wenn der Rand 11 über den oberen Bogenabschnitt des Endstückes 30 gezogen ist. Hierdurch wird die Versteifungsplatte 2 durch die vom Endstück 30 ausgeübte Reibungskraft zusätzlich gebremst, so daß die Lasche 5 bereits vor dem Freiwerden der Versteifungsplatte 2 soweit aus den Führungsleisten 4 herausgezogen werden kann, daß ihr undurchbrochener Abschnitt die Einlaßöffnung 3 verschließt.If, on the other hand, the stiffening plate 2 is also pulled upwards when the tab 7 is pulled up, despite the weight of the filter bag 1, then the tab 5 is automatically moved relative to the stiffening plate 2 when both disengage from the end piece 30, after which the weight of the filter bag 1, the stiffening plate 2 moves downward against the tensile force on the handle 7 and the unbroken section of the tab 5 comes into overlap with the inlet opening 3. In this case, if the lower edge 11 of the tab 5 is shorter than the stiffening plate 2, then the rubber-elastic end piece with its increased frictional force will in any case only engage the stiffening plate 2 when the edge 11 is pulled over the upper arc section of the end piece 30 is. As a result, the stiffening plate 2 is additionally braked by the frictional force exerted by the end piece 30, so that the tab 5 can be pulled out of the guide strips 4 so far before the stiffening plate 2 becomes free that its unbroken section closes the inlet opening 3.

Der zum Deckel 28 gerichtete Rand bzw. die Handhabe 7 der Lasche 5 reicht bei ordnungsgemäß eingesetzter Versteifungsplatte 2 und Lasche 5 bis knapp an die Unterseite des Deckels 28. Wenn demnach beim Einsetzen die Versteifungsplatte 2 nicht ausreichend tief in die Führungsschienen 26 eingeschoben oder die Lasche 5 nicht in ihre Sollposition gemäß Figur 10 gestellt ist, dann wird über die Handhabe 7 beim Schließen des Deckels die Anordnung aus Versteifungsplatte 2 und Lasche 5 in die Sollposition geschoben. Wenn das nicht möglich ist, wird der Deckel in einer Öffnungsposition gehalten, so daß ein Hinweis auf eine fehlerhafte Funktion gegeben ist. Bei geöffnetem Deckel 28 kann auch ein ausreichender Unterdruck im Staubbeutelraum 27 nicht aufgebaut werden. Damit ist sichergestellt, daß ein Saugbetrieb nur bei richtig eingesetztem Filter möglich ist. Insbesondere jedoch wird der Staubbeutel beim Herausziehen aus dem Gerät automatisch verschlossen, so daß ein hygienischer, sauberer Staubbeutelwechsel erreicht wird. Selbst durch Drücken auf den Staubbeutel kann Staub nicht aus der Einlaßöffnung austreten. Die Nutzungsmöglichkeiten der Lasche 5 bzw. des ganzen Filters sind daher wesentlich erhöht.The edge directed towards the cover 28 or the handle 7 of the tab 5 extends with the stiffening plate 2 and tab 5 correctly inserted to just below the underside of the lid 28. If the stiffening plate 2 is therefore not inserted sufficiently deep into the guide rails 26 or the tab when inserted 5 not in their target position according to FIG 10 is set, then the arrangement of stiffening plate 2 and tab 5 is pushed into the desired position by means of the handle 7 when the lid is closed. If this is not possible, the lid is held in an open position so that there is an indication of a malfunction. When the cover 28 is open, a sufficient negative pressure cannot be built up in the dust bag space 27. This ensures that suction operation is only possible if the filter is correctly inserted. In particular, however, the dust bag is automatically closed when it is pulled out of the device, so that a hygienic, clean dust bag change is achieved. Even by pressing the dust bag, dust cannot escape from the inlet opening. The possible uses of the tab 5 or the entire filter are therefore significantly increased.
