Description

Die vorliegende Erfindung betrifft eine Filtereinrichtung für einen Staubsauger.The present invention relates to a filter device for a vacuum cleaner.

Beim Wechseln der in Rede stehenden Filtereinrichtung passiert es, daß Schmutz aus dem Beutel in dem Raum durch die Einströmöffnung der Halteplatte gelangt. Zur Lösung dieses Problems ist es beispielsweise aus der EP-A-362 624 bekannt, die Einströmöffnung der Halteplatte mittels eines verfahrbaren Schiebers zu verschließen. Dieser Schieber hat eine der Kontur der Einströmöffnung entsprechende Durchbrechung. Zur Führung des Schiebers sind an der Halteplatte an der dem Filterbeutel abgewandten Seite Leisten angesetzt. Diese vorbekannte Filtereinrichtung ist aufwendig und läßt sich nur mit einem entsprechend hohen Aufwand herstellen. Außerdem muß der Schieber von Hand in die durch die Leisten gebildete Führung eingesetzt werden. Ferner ist ein Klebstoff notwendig. Darüber hinaus ist die Bauhöhe der Halteplatte verhältnismäßig groß.When changing the filter device in question, it happens that dirt comes out of the bag in the room through the inflow opening of the holding plate. To solve this problem, it is known, for example from EP-A-362 624, to close the inflow opening of the holding plate by means of a movable slide. This slide has an opening corresponding to the contour of the inflow opening. To guide the slide, strips are attached to the holding plate on the side facing away from the filter bag. This known filter device is complex and can only be produced with a correspondingly high outlay. In addition, the slide must be inserted by hand into the guide formed by the strips. An adhesive is also required. In addition, the height of the holding plate is relatively large.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Filtereinrichtung der eingangs genannten Art so auszubilden, ohne Verwendung eines Klebers die Filtereinrichtung in materialsparender Weise einfach herzustellen ist, wobei die Bauhöhe der Halteplatte äußerst gering ist. Außerdem soll die Verschlußplatte maschinell in die Funktionsstellung gebracht werden.The present invention is based on the object of designing a filter device of the type mentioned at the outset in such a way that the filter device can be easily produced in a material-saving manner without using an adhesive, the overall height of the holding plate being extremely low. In addition, the closure plate is to be brought into the functional position by machine.

Aus der vorangemeldeten, nachveröffentlichten EP-A-439 700 (Stand der Technik nach Artikel 54(3)EPÜ) ist ein Verfahren zur Herstellung eines Anschlußstücks für Filtersäcke oder dergleichen zu entnehmen, bei dem gemäß dem Ausführungsbeispiel nach den Figuren 11 bis 15 zunächst zur Bildung der Halte- und der Verschlußplatte ein einstückiger Formling gestanzt wird. Zur Bildung der Verschlußplatte ist der Formling mit Sollreißstellen versehen. Die Führung der Verschlußplatte erfolgt durch auf die Verschlußplatte gefaltete streifenförmige Zuschnittsbereiche, so daß drei Materiallagen aufeinander liegen. Zum Verschließen der Einströmöffnung der Halteplatte muß die Verschlußplatte entlang der Sollreißstellen gerissen werden. Dazu ist ein besonders hoher Kraftaufwand notwendig, so daß mit einer Hand die Verschlußplatte abgerissen und mit der anderen Hand die Halteplatte gegriffen werden muß.From the previously published, post-published EP-A-439 700 (prior art according to Article 54 (3) EPC), a method for producing a connector for filter bags or the like can be seen, in which according to the embodiment of Figures 11 to 15 initially for Formation of the holding and the closure plate an integral molding is punched. The molding is provided with predetermined tear points to form the closure plate. The closure plate is guided by strip-shaped blank areas folded onto the closure plate, so that three layers of material lie on top of one another. To close the inflow opening of the holding plate, the closing plate must be torn along the predetermined tear points. This requires a particularly high level of force, so that the closure plate has to be torn off with one hand and the holding plate has to be gripped with the other hand.

Die gestellte Aufgabe wird durch eine Filtereinrichtung für einen Staubsauger mit einem Filterbeutel und einer daran befestigten, mit einer Einströmöffnung versehenen Halteplatte und mit einer in ihrer Längsrichtung verschiebbaren, mit einer Durchbrechung versehenen Verschlußplatte, die in eine die Einströmöffnung der Halteplatte freigebende und abdeckende Stellung bringbar ist, wobei die Halteplatte und die Verschlußplatte als ein einstückiges, aus einem Stanzling durch Faltung hergestelltes Formteil ausgebildet sind und der Verschlußplatte quer zu ihrer Verschieberichtung verlaufende Lamellen zugeordnet sind, gelöst. Da die Halteplatte und die Verschlußplatte ein einstückiges Formteil sind, ist nicht nur die Fertigung äußerst einfach, da beide Teile in einem Stanzvorgang hergestellt werden, sondern darüber hinaus läßt sich die Verschlußplatte verschieben durch den aus den einzelnen Lamellen gebildeten Bereich, der als eine Jalousie zu bezeichnen ist. Die Herstellung des Lamellenbereichs ist besonders einfach, wenn die einzelnen Lamellen durch quer zur Verschieberichtung der Verschlußplatte verlaufende, zur Bildung von Filmscharnieren sich über eine Teildicke des Formteiles erstreckende Einschnitte gebildet sind. Die Tiefe dieser Einschnitte ist ein klein wenig geringer als die Dicke des jeweiligen Lamellenbereichs. Damit durch die verschiebbare Verschlußplatte die Einströmöffnung der Halteplatte abgedeckt und freigegeben werden kann, ist vorgesehen, daß die Lamellen zumindest im Übergangsbereich von der Halteplatte zur Verschlußplatte angeordnet sind. Dieser Übergangsbereich könnte auch als Umlenkbereich bezeichnet werden, dessen äußere Kante sich beim Bewegen der Verschlußplatte verschiebt.The object is achieved by a filter device for a vacuum cleaner with a filter bag and an attached holding plate provided with an inflow opening and with a longitudinally displaceable closing plate provided with an opening, which can be brought into a position that exposes and covers the inflow opening of the holding plate , wherein the holding plate and the closure plate are formed as a one-piece, made from a die-cut by folding and the closure plate are assigned to transverse to their displacement slats are assigned. Since the holding plate and the closure plate are a one-piece molded part, not only is the manufacture extremely simple since both parts are produced in one punching process, but the closure plate can also be moved through the area formed from the individual slats, which can be called a blind. The manufacture of the lamella area is particularly simple if the individual lamellae are formed by incisions extending transversely to the direction of displacement of the closure plate and extending over a partial thickness of the molded part to form film hinges. The depth of these incisions is a little less than the thickness of the respective lamella area. So that the inflow opening of the holding plate can be covered and released by the displaceable closure plate, it is provided that the slats are arranged at least in the transition region from the holding plate to the closure plate. This transition area could also be referred to as a deflection area, the outer edge of which shifts when the closure plate is moved.

In Vorteilhafter Ausgestaltung ist vorgesehen, daß die Einschnitte parallel und in einem relativ geringen Abstand zueinander angeordnet sind und daß die einen ersten Bereich bildenden Einschnitte an einer Seite des Formteils und die einen zweiten Bereich bildenden Einschnitte an der anderen Seite des Formteils vorgesehen sind. Dadurch wird ein Papiereffekt erzielt, so daß der gesamte Lamellenbereich ausweichen kann, wenn die Lamellen gegen ein Hindernis stoßen, wenn die Verschlußplatte so verfahren wird, daß die Einströmöffnung der Halteplatte freigegeben wird. Da dieses Ausweichen zu der dem Filterbeutel abgewandten Seite hin erfolgen soll, ist vorgesehen, daß, bezogen auf die Schließstellung der Verschlußplatte, die der Durchbrechung der Verschlußplatte abgewandten Einschnitte an der der Halteplatte abgekehrten Seite die der Durchbrechung der Verschlußklappe zugewandten Einschnitte an der der Halteplatte zugekehrten Seite vorgesehen sind.In an advantageous embodiment it is provided that the incisions are arranged parallel and at a relatively small distance from one another and that the incisions forming a first region are provided on one side of the molded part and the incisions forming a second region are provided on the other side of the molded part. This achieves a paper effect, so that the entire slat area can dodge if the slats hit an obstacle, if the closure plate is moved so that the inflow opening of the holding plate is released. Since this evasion should take place on the side facing away from the filter bag, it is provided that, based on the closed position of the closure plate, the incisions facing away from the opening of the closure plate on the side facing away from the holding plate, the incisions facing the opening of the closure flap on the side facing the holding plate Side are provided.

Gemäß einer anderen Ausführungsform ist vorgesehen, daß die Verschlußplatte aus mehreren Lamellen besteht, die in der die Einströmöffnung freigebenden Stellung nach Art eines Leporellos senkrecht oder annähernd senkrecht zur Halteplatte stehen. Typbedingt kann es sein, daß ein seitliches Überstehen gegenüber der Halteplatte nicht möglich ist. In diesen Fällen ist dann diese Ausführung zu bevorzugen. Dabei ist es denkbar, daß die die Verschlußplatte bildenden Lamellen die beiden äußeren Bereiche des Stanzlinges sind, so daß nach dem Umfalten dieser Bereiche die Verschlußplatte sinngemäß zweiteilig ist. Die Lamellen jeder Seite werden zur Freigabe der Einströmöffnung dann zur Seite geschoben und aufgerichtet.According to another embodiment, it is provided that the closure plate consists of a plurality of lamellae which, in the position in which the inflow opening is open, are perpendicular or approximately perpendicular to the holding plate in the manner of a fan. Depending on the type, there may be a side overhang the holding plate is not possible. In this case, this version is preferred. It is conceivable that the lamellae forming the closure plate are the two outer regions of the die-cut part, so that after these regions have been folded over, the closure plate is essentially in two parts. The slats on each side are then pushed to the side to open the inflow opening and raised.

Die in der Figur 1 dargestellte Filtereinrichtung 10 besteht aus einem andeutungsweise gezeichneten Filterbeutel 11, einer mit einer Einströmöffnung 12 versehenen Halteplatte 13 und einer einstückig mit der Halteplatte 13 verbundenen Verschlußplatte 14, die mit einer Durchbrechung 15 versehen ist.
Der Filterbeutel 11 ist an der der Verschlußplatte 14 abgewandten Seite der Halteplatte 13 in nicht näher erläuteter Weise befestigt. Die Halteplatte 13 und die Verschlußplatte 14 sind aus einem Kartonstanzling durch Faltung gefertigt, so daß die Halteplatte 13 und die Verschlußplatte 14 im Sinne eines zweilagigen Formteils zu sehen sind. Die Einströmöffnung 12 der Halteplatte 13 ist im dargestellten Ausführungsbeispiel zentrisch angeordnet und kreisrund ausgebildet.
Die Figur 2 zeigt, daß die Durchbrechung der Verschlußplatte 14 im Durchmesser ein klein wenig größer ist als die Einströmöffnung 12. Der Übergangsbereich zwischen der Halteplatte 13 und der Verschlußplatte 14, das ist der Bereich, der die Verschiebung der Verschlußplatte 14 gegenüber der Halteplatte 13 zulassen muß, ist in den dargestellten Ausführungsbeispielen durch eine Vielzahl von quer zur Verschieberichtung der Verschlußplatte 14 verlaufenden Lamellen 16 gebildet.
Die einzelnen Lamellen sind durch Einschnitte 17 gebildet, die sich nicht über die gesamte Dicke der Materiallage erstrecken, so daß sie durch einzelne Filmscharniere miteinander verbunden sind. Wie ein Vergleich der Figuren 1 und 2 zeigt, liegen die Einschnitte 17 zur Bildung der Lamellen 16 bei durch die Verschlußplatte 14 verschlossener Einströmöffnung 12 an der der Halteplatte 13 abgewandten Seite. Außerdem erstrecken sie sich von der unteren Kante bis in den Bereich der Einströmöffnung 12. Bei freier Einströmöffnung 12 liegen die Einschnitte 17 an der der Halteplatte 13 zugewandten Seite. Die Höhe der einzelnen Lamellen beträgt beispielsweise 3 mm, so daß das Abrollen beim Bewegen der Verschlußplatte 14 sehr flach erfolgt. Der Lamellenbereich ist auch als Übergangsbereich oder Verbindungsbereich zwischen der Halteplatte 13 und der Verschlußplatte 14 zu sehen.
The filter device 10 shown in FIG. 1 consists of an indicated filter bag 11, a holding plate 13 provided with an inflow opening 12 and a closure plate 14 which is integrally connected to the holding plate 13 and which is provided with an opening 15.
The filter bag 11 is fastened to the side of the holding plate 13 facing away from the closure plate 14 in a manner not explained in more detail. The holding plate 13 and the closure plate 14 are made from a cardboard die-cut by folding, so that the holding plate 13 and the closure plate 14 can be seen in the sense of a two-layer molded part. The inflow opening 12 of the holding plate 13 is arranged centrally in the illustrated embodiment and is circular.
Figure 2 shows that the opening of the closure plate 14 is slightly larger in diameter than the inflow opening 12. The transition region between the holding plate 13 and the closure plate 14, that is the area that allow the displacement of the closure plate 14 relative to the holding plate 13 must be formed in the illustrated embodiments by a plurality of transverse to the displacement direction of the closure plate 14 slats 16.
The individual lamellae are formed by cuts 17 which do not extend over the entire thickness of the material layer, so that they are connected by individual film hinges. As a comparison of FIGS. 1 and 2 shows, the incisions 17 for forming the slats 16 lie on the side facing away from the holding plate 13 when the inflow opening 12 is closed by the closure plate 14. In addition, they extend from the lower edge to the area of the inflow opening 12. With the free inflow opening 12, the incisions 17 lie on the side facing the holding plate 13. The height of the individual slats is, for example, 3 mm, so that the rolling takes place very flat when the closure plate 14 is moved. The lamella area can also be seen as a transition area or connecting area between the holding plate 13 and the closure plate 14.

Bei der Ausführung nach der Figur 3 sind die Einschnitte 17 zur Bildung der Lamellen 16 an zwei verschiedenen Seiten vorgesehen. Die beiden Bereiche sind gleich breit. Im dargestellten Ausführungsbeispiel ist es so, daß die der unteren Kante zugeordneten Einschnitte 17, d. h. die der Durchbrechung 15 abgewandten Einschnitte an der der Halteplatte 13 abgekehrten Seite und die der Durchbrechung 15 der Verschlußplatte 14 zugeordneten Einschnitte 17 an der der Halteplatte 13 zugekehrten Seite liegen. Dadurch ist es möglich, daß der aus den Lamellen 16 gebildete Bereich sich beim Verschieben der Verschlußplatte 14 bogenförmig ausbilden kann, d. h. im vorliegenden Ausführungsbeispiel von der Halteplatte 13 weggerichtet. Diese Ausführung ist dann vorteilhaft, wenn der aus den Lamellen 16 gebildete Bereich bei freigegebener Einströmöffnung 12 im Staubsaugergehäuse keinen Platz findet, da dann die Lamellen ausweichen können. Die Figur 4 zeigt in vergrößerter Darstellung die Lage der Einschnitte 17 und der Lamellen 16 bei freigegebener Einströmöffnung 12. Die Figuren 5 bis 8 zeigen, daß die Halteplatte 13 und die Verschlußplatte 14 mit den einander zugewandten Flächen dicht aneinanderliegen. Die Figuren 5 bis 7 zeigen außerdem, wie die Lamellen 16 durch die Einschnitte gemäß der Figur 3 gebildet wurden. Dabei stimmen die beiden Lagen der Verschlußplatte 14 in den Figuren 3 und 7 überein. Zur Führung der Verschlußplatte 14 sind den beiden Längskanten jeweils zwei Einschnitte 18, 19 zugeordnet, die in der Halteplatte 13 vorgenommen wurden. Durch die Einschnitte 18, 19 werden Führungslaschen 20, 21 gebildet, die im dargestellten Ausführungsbeispiel bogenförmig sind. Die Einschnitte 18, 19 sind Formschnitte, die im mittelren Bereich bogenförmig ausgebildet sind und in den beiden Endbereichen zueinander fluchten und außerdem parallel und in einem geringen Abstand zu den Längskanten der Verschlußkante 14 verlaufen.
Die Führungslaschen 20, 21 übergreifen die Verschlußplatte 14.
In the embodiment according to FIG. 3, the incisions 17 are provided on two different sides to form the slats 16. The two areas are the same width. In the illustrated embodiment, it is the case that the cuts 17 associated with the lower edge, ie the cuts facing away from the opening 15, are on the side facing away from the holding plate 13 and the cuts 17 associated with the opening 15 of the closure plate 14 are on the side facing the holding plate 13. This makes it possible for the area formed from the slats 16 to form an arc when the closure plate 14 is moved, that is to say directed away from the holding plate 13 in the present exemplary embodiment. This embodiment is advantageous if the area formed from the slats 16 has no space in the vacuum cleaner housing when the inflow opening 12 is open, since the slats can then deflect. FIG. 4 shows the position of the incisions 17 in an enlarged representation and the fins 16 with the inflow opening 12 open. FIGS. 5 to 8 show that the holding plate 13 and the closure plate 14 lie closely against one another with the surfaces facing one another. FIGS. 5 to 7 also show how the slats 16 were formed by the incisions according to FIG. 3. The two layers of the closure plate 14 in FIGS. 3 and 7 match. To guide the closure plate 14, two incisions 18, 19 are made in each case in the two longitudinal edges, which were made in the holding plate 13. Through the incisions 18, 19 guide tabs 20, 21 are formed, which are arc-shaped in the illustrated embodiment. The incisions 18, 19 are shaped cuts which are arch-shaped in the central region and are aligned with one another in the two end regions and also run parallel and at a short distance from the longitudinal edges of the closure edge 14.
The guide tabs 20, 21 overlap the closure plate 14.

Die Verschlußplatte 14 gemäß dem Ausführungsbeispiel nach den Figuren 9 und 10 ist aus insgesamt sechs Verschlußlamellen 22 gebildet, die in der die Einströmöffnung 12 freigebenden Stellung leporelloartig gefaltet sind und senkrecht zur Halteplatte stehen. Auch diese Verschlußlamellen 22 sind durch entsprechende Einschnitte gebildet, die im ständigen Wechsel an den beiden Seiten vorgesehen sind, wie die Figur 10 zeigt. Im dargestellten Ausführungsbeispiel werden die Verschlußlamellen zur Freigabe der Einströmöffnung 12 nach oben und unten geschoben. Bei dem entsprechenden Stanzling liegen sie dann an den beiden Enden. Aus Darstellungsgründen sind die oberen Verschlußlamellen in der aufgerichteten Stellung, die unteren in der abdeckenden Stellung dargestellt.The closure plate 14 according to the exemplary embodiment according to FIGS. 9 and 10 is formed from a total of six closure lamellae 22, which are folded like a leporello in the position opening the inflow opening 12 and are perpendicular to the holding plate. These closure lamellae 22 are also formed by corresponding incisions which are provided in alternation on both sides, as shown in FIG. In the illustrated embodiment, the closure slats are pushed up and down to release the inflow opening 12. With the corresponding die cut, they are then at both ends. For reasons of illustration, the upper closure slats are shown in the erected position, the lower ones in the covering position.

Es ist denkbar, daß die Verschlußlamellen 22 zur rechten oder zur linken Seite oder auch zu beiden Seiten geschoben werden. Zur Führung der Verschlußlamellen 22 sind an den einander zugewandt liegenden Lamellen stirnseitig jeweils Führungsansätze 23 angesetzt, die in Langlöchern 24 der Halteplatte 13 geführt sind. Diese Ausführung bietet den Vorteil, daß die Verschlußlamellen 22 gegenüber den Seitenkanten der Halteplatte 13 nicht vorstehen. Außerdem entfällt die Durchbrechung um die Einströmöffnung 12 freizugeben.It is conceivable that the closure slats 22 are pushed to the right or to the left or to both sides. In order to guide the closure slats 22, guide lugs 23 are attached to the mutually facing slats on the end faces, which are guided in elongated holes 24 in the holding plate 13. This embodiment has the advantage that the closure slats 22 do not protrude from the side edges of the holding plate 13. In addition, there is no opening to expose the inflow opening 12.
