Description

Die Erfindung betrifft einen Staubsaugerfilterbeutel mit einer steifen Halteplatte gemäß dem Oberbegriff des Ansprüches 1.The invention relates to a vacuum cleaner filter bag with a rigid holding plate according to the preamble of claim 1.

Ein solcher Filterbeutel ist durch die US-A-2 864 462 bekannt. Bei diesem Filterbeutel sind am einen Ende des Streifens seitlich vorstehende Laschen angeordnet, die beim Verschieben des Streifens in seine die Einlaßöffnung des Filterbeutels überdeckende Schließstellung auf in der Führungsbahn zwischen den Lagen der Halteplatte vorgesehene Begrenzungsanschläge treffen. Hierdurch wird verhindert, daß der Streifen über die Schließstellung hinaus zwischen den Lagen herausgezogen werden kann. Bei diesem Filterbeutel besteht allerdings die Gefahr, daß beim Einsetzen des Filterbeutels in einen Staubsauger gegen das andere Ende des Streifens gestoßen und der Streifen dadurch verschoben wird. Damit wird die Einlaßöffnung zumindest teilweise von dem Streifen überdeckt, so daß es zu Schwierigkeiten beim Betrieb des Staubsaugers kommt.Such a filter bag is known from US-A-2 864 462. In this filter bag laterally projecting tabs are arranged at one end of the strip, which meet the limit stops provided in the guideway between the layers of the holding plate when the strip is moved into its closed position covering the inlet opening of the filter bag. This prevents the strip from being pulled out between the layers beyond the closed position. With this filter bag, however, there is a risk that when the filter bag is inserted into a vacuum cleaner, it will bump against the other end of the strip and the strip will be displaced as a result. So that the inlet opening is at least partially covered by the strip, so that there are difficulties in the operation of the vacuum cleaner.

Durch die DE-A-24 07 478 ist ferner ein Filterbeutel bekannt, bei dem der Streifen aus einem elastischen Material besteht. Bei diesem Filterbeutel ist der Streifen im Bereich seines einen Endes zusammengefaltet und mit diesem Ende an einer oder beiden Lagen der Halteplatte befestigt. In dieser gefalteten Stellung deckt sich das am Streifen vorgesehene Loch mit der Einlaßöffnung der Halteplatte. Das andere Ende des Streifens steht etwas über den Begrenzungsrand der Halteplatte vor, so daß der Streifen an diesem Ende leicht erfaßt und straff gezogen werden kann, so daß das Loch von der Einlaßöffnung wegbewegt und diese somit durch den Streifen verschlossen wird. Ein solches Straffen des Streifens soll vor der Entnahme eines mit Schmutz gefüllten Filterbeutels aus dem Staubraum eines Staubsaugers erfolgen, um ein Entweichen von Schmutz aus der Einlaßöffnung zu verhindern. Bei der Handhabung eines noch leeren Filterbeutels kann es allerdings vorkommen, daß versehentlich an dem Streifenende gezogen und damit die Einlaßöffnung verschlossen wird. Es besteht dann keine Möglichkeit mehr, die Einlaßöffnung ohne Zerstörung des Streifens wieder frei zu bekommen.From DE-A-24 07 478 a filter bag is also known in which the strip consists of an elastic material. In the case of this filter bag, the strip is folded up in the region of its one end and fastened to one or both layers of the holding plate with this end. In this folded position, the hole provided on the strip coincides with the inlet opening of the holding plate. The other end of the strip protrudes slightly beyond the boundary edge of the holding plate, so that the strip can be easily grasped and pulled tight at this end, so that the hole is moved away from the inlet opening and is thus closed by the strip. Such tightening of the strip is said to take place before the removal of a Filter bag filled with dirt from the dust chamber of a vacuum cleaner to prevent dirt from escaping from the inlet opening. When handling a still empty filter bag, however, it can happen that the end of the strip is accidentally pulled, thereby closing the inlet opening. It is then no longer possible to clear the inlet opening without destroying the strip.

In der älteren, nicht vorveröffentlichten EP-A-0 362 624 wird ein Staubsaugerfilterbeutel beschrieben, an dessen Versteifungsplatte eine parallel zu dieser geführte, verstellbare Lasche vorgesehen ist.In the older, not previously published EP-A-0 362 624, a vacuum cleaner filter bag is described, on the stiffening plate of which an adjustable tab is provided which is guided parallel to the latter.

Diese Lasche weist einen Durchbruch auf, der in der Arbeitsstellung der Lasche mit einer an der Versteifungsplatte vorgesehenen Einlaßöffnung fluchtet. Die Lasche kann zwischen der Arbeitsstellung und einer Sperrstellung, in der die Lasche mit einem undurchbrochenen Abschnitt die Einlaßöffnung überdeckt verschoben werden, wobei der Verstellweg der Lasche in diesen beiden Stellungen durch Anschlagglieder begrenzt wird. Nachteilig ist, daß die Lasche, insbesondere beim Einsetzen eines solchen Filterbeutels in den Staubsauger, durch ungewolltes Betätigen auch in zwischen den beiden Endstellungen liegende Stellungen gebracht werden kann, wodurch die Handhabung des Filterbeutels erschwert wird.This tab has a breakthrough which is aligned with an inlet opening provided on the stiffening plate in the working position of the tab. The tab can be moved between the working position and a blocking position in which the tab covers the inlet opening with an unbroken section, the adjustment path of the tab being limited in these two positions by stop members. It is disadvantageous that the tab, in particular when such a filter bag is inserted into the vacuum cleaner, can also be brought into positions lying between the two end positions by inadvertent actuation, which makes handling of the filter bag difficult.

Der Erfindung liegt die Aufgabe zugrunde, einen Filterbeutel der eingangs beschriebenen Art so auszubilden, daß ein unbeabsichtigtes Betätigen des Streifens in der einen oder anderen Richtung ausgeschlossen ist.The invention has for its object to design a filter bag of the type described in such a way that inadvertent actuation of the strip in one direction or the other is excluded.

Die Lösung der gestellten Aufgabe gelingt durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale.The problem is solved by the features specified in the characterizing part of claim 1.

Durch die Verbindung des Anschlaggliedes mit der entsprechenden Lage bzw. mit beiden Lagen der Halteplatte wird einerseits ein unbeabsichtigtes Herausziehen des Streifens und ein damit verbundenes Verschließen der Einlaßöffnung verhindert. Andererseits kann die als Sollbruchstelle ausgebildete Verbindung leicht zerstört werden, wenn bei Entnahme des mit Schmutz gefüllten Filterbeutels, dessen Einlaßöffnung verschlossen werden soll, um ein Entweichen von Schmutz bei der Entsorgung des Filterbeutels zu verhindern. Zur leichteren Handhabung kann an dem Anschlagglied eine Grifföffnung vorgesehen werden.By connecting the stop member with the corresponding position or with both layers of the holding plate on the one hand an unintentional pulling out of the strip and an associated closing of the inlet opening prevented. On the other hand, the connection designed as a predetermined breaking point can easily be destroyed if, with removal of the Dirt-filled filter bag, the inlet opening of which is to be closed in order to prevent dirt from escaping when the filter bag is disposed of. A handle opening can be provided on the stop member for easier handling.

Um ein sicheres Abtrennen des Anschlaggliedes von der Halteplatte zu erreichen, werden als Sollbruchstelle im Bereich der Seiten kante der Halteplatte schmale Verbindungsstege zwischen dem Anschlagglied und der Halteplatte vorgesehen. Bei doppellagiger Ausführung des Anschlaggliedes wird der Streifen mit seinem anderen Ende zweckmäßigerweise zwischen den Lagen des Anschlaggliedes befestigt.In order to achieve a safe separation of the stop member from the holding plate, narrow connecting webs between the stop member and the holding plate are provided as a predetermined breaking point in the region of the side edge of the holding plate. In the case of a double-layer design of the stop element, the strip is expediently fastened with its other end between the layers of the stop element.

Um ein Verklemmen der Schleife zu vermeiden, wird diese auf der dem Anschlagglied gegenüberliegenden Seite zwischen den beiden Lagen der Halteplatte nach außen herausgeführt.In order to avoid jamming of the loop, it is led out to the outside on the side opposite the stop member between the two layers of the holding plate.

Ein sicheres Zerreißen der die Sollbruchstelle verbindenden Stege wird dadurch erreicht, daß die Halteplatte mittels an ihr vorgesehener Rastelemente mit entsprechenden Gegenrastelementen, die an der die Halteplatte aufnehmenden Führung vorgesehen sind, verrastet ist.A safe tearing of the webs connecting the predetermined breaking point is achieved in that the holding plate is locked by means of locking elements provided on it with corresponding counter-locking elements which are provided on the guide receiving the holding plate.

Ein leichtes Auftrennen der Sollbruchstelle ist dadurch möglich, daß das Anschlagglied umknickbar ist. Somit können die das Anschlagglied mit der Halteplatte verbindenden Stege durch bloßes Umknicken des Anschlaggliedes gegenüber der Halteplatte durchtrennt werden. Ist das Anschlagglied im Mittenbereich über der Einlaßöffnung dach- oder bogenförmig ausgebildet, wobei die Dachspitze bzw. die Wölbung des Bogens zur Einlaßöffnung weist, dann treten beim Umknicken des Anschlaggliedes im Randbereich an den Seitenkanten höhere Kräfte auf, die mit Sicherheit zu einem Zerreißen der Verbindungsstege führen. Ein selbsttätiges Auftrennen der Sollbruchstelle nach dem Einsetzen des Filterbeutels in den Staubraum eines Staubsaugers wird dadurch erreicht, daß das Anschlagglied derart bemessen ist, daß es mit seinem freien Begrenzungsrand in den Schließweg eines an dem den Staubraum eines Staubsaugers verschließenden Deckel angeordneten Abknickelementes ragt.An easy opening of the predetermined breaking point is possible in that the stop member can be bent. Thus, the webs connecting the stop member to the holding plate can be severed by simply bending the stop member relative to the holding plate. If the stop member is roof-shaped or arch-shaped in the middle region above the inlet opening, with the roof tip or the arch of the arch facing the inlet opening, then higher forces occur when the stop member bends in the edge region at the side edges, which will certainly tear the connecting webs to lead. An automatic opening of the predetermined breaking point after inserting the filter bag in the dust chamber of a vacuum cleaner is achieved in that the stop member is dimensioned such that it projects with its free boundary into the closing path of a bend element arranged on the lid closing the dust chamber of a vacuum cleaner.

Anhand in der Zeichnung dargestellter Ausführungsbeispiele wird der Anmeldungsgegenstand nachfolgend näher beschrieben. Es zeigt:

The subject of the application is described in more detail below with reference to exemplary embodiments shown in the drawing. It shows:
FIG. 1
cut a vacuum cleaner filter bag,
FIG 2
a plan view of the holding plate of a vacuum cleaner filter bag, in which the one layer is removed,
FIG 3
another embodiment of a holding plate of a vacuum cleaner filter bag,
FIG 4
a vacuum cleaner filter bag in section along the line IV-IV in Figure 3.

Mit 1 ist ein Staubsaugerfilterbeutel bezeichnet, der mit einer eine Einlaßöffnung 2 aufweisenden, aus zwei Fapplagen 3 und 4 bestehenden Halteplatte 5 versehen ist. Die beiden Papplagen 3,4 sind nur in ihrem Randbereich 6 miteinander verbunden, so daß zwischen ihnen ein elastischer Streifen 7 beweglich eingefügt werden kann.1 with a vacuum cleaner filter bag is designated, which is provided with an inlet opening 2, consisting of two cardboard layers 3 and 4 holding plate 5. The two cardboard layers 3, 4 are connected to one another only in their edge region 6, so that an elastic strip 7 can be inserted between them in a movable manner.

Bei dem in den FIG 1 und 2 dargestellten Staubsaugerfilterbeutel ist an den beiden Enden des Streifens 7 jeweils eine als Anschlagglied dienende, seitlich über den Streifen 7 vorstehende untere und obere Leiste 8 bzw.9 angeformt. Die dem in Gebrauchslage des Filterbeutels oberen Begrenzungsrand 10 der Halteplatte 5 benachbarte obere Leiste 9 weist eine Grifföffnung 11 auf. Ferner ist der Streifen 7 mit einem Loch 12 versehen, das sich bei Anlage der oberen Leiste 9 an dem oberen Begrenzungsrand 10 der Halteplatte 5 mit deren Einlaßöffnung 2 deckt.In the vacuum cleaner filter bag shown in FIGS. 1 and 2, a lower and upper bar 8 and 9, which projects laterally beyond the strip 7, is molded onto the two ends of the strip 7. The upper bar 9 adjacent to the upper boundary edge 10 of the holding plate 5 in the position of use of the filter bag has a handle opening 11. Furthermore, the strip 7 is provided with a hole 12 which coincides with the upper opening 9 on the upper boundary edge 10 of the holding plate 5 with its inlet opening 2.

Ist der in einen Staubsauger eingesetzte Filterbeutel 1 mit Schmutz gefüllt und muß ausgetauscht werden, so wird die Grifföffnung 11 der oberen Leiste erfaßt und der Streifen 7 nach oben gezogen. Hierdurch wird zunächst das Loch 12 von der Einlaßöffnung 2 wegbewegt und somit dieselbe durch den Streifen 7 abgedeckt. Sobald die untere Leiste 8 mit ihren seitlich überstehen den Enden 13 auf die Unterkante 14 der Halteplatte 5 auftrifft, wird die Halteplatte 5 nunmehr mittels des Streifens 7 aus der Führung im Staubsaugergehäuse herausgezogen. Es besteht auch die Möglichkeit an dem Streifen 7 die untere Leiste 8 wegzulassen und das Ende des Streifens 7 außen an der Halteplatte 5 zu befestigen.If the filter bag 1 inserted into a vacuum cleaner is filled with dirt and has to be replaced, the handle opening 11 of the upper bar is grasped and the strip 7 is pulled upwards. As a result, the hole 12 is first moved away from the inlet opening 2 and thus covered by the strip 7. As soon as the lower bar 8 with its laterally projecting ends 13 strikes the lower edge 14 of the holding plate 5, the holding plate 5 is now pulled out of the guide in the vacuum cleaner housing by means of the strip 7. It is also possible to omit the lower strip 8 on the strip 7 and to fasten the end of the strip 7 on the outside of the holding plate 5.

Wird der Streifen 7 beim Herausnehmen eines leeren Filterbeutels aus einer Vorratspackung oder beim Einsetzen des Filterbeutels in den Staubraum versehentlich betätigt, so daß sich das Loch 12 nicht mehr mit der Einlaßöffnung 2 deckt, kann durch Ziehen an der entsprechenden Leiste 8 bzw.9 wieder die Deckungsgleichheit hergestellt werden. Das Loch 12 wird an dem Streifen 7 zweckmäßigerweise so angeordnet, daß es sich bei Anlage der oberen Leiste 9 am oberen Begrenzungsrand 10 mit der Einlaßöffnung 2 deckt. Damit braucht der Streifen 7 lediglich bis zum Anschlag der oberen Leiste 9 auf den oberen Begrenzungsrand 10 zwischen den Fapplagen 3 und 4 durchgezogen werden, um die Deckungsgleichheit zu erreichen.If the strip 7 is inadvertently actuated when removing an empty filter bag from a storage pack or when inserting the filter bag into the dust space, so that the hole 12 no longer coincides with the inlet opening 2, the corresponding bar 8 or 9 can be pulled again by pulling it Congruity can be established. The hole 12 is conveniently arranged on the strip 7 so that it coincides with the inlet opening 2 when the upper bar 9 is in contact with the upper boundary edge 10. Thus, the strip 7 only needs to be pulled up to the stop of the upper bar 9 on the upper boundary edge 10 between the cardboard layers 3 and 4 in order to achieve congruence.

Bei der Ausführungsform nach den FIG 3 und 4 ist der Streifen 7 mit seinem einen Ende 15 im Bereich des unteren Begrenzungsrandes der Halteplatte 5 an der einen Papplage 4 befestigt, z.B. angeklebt. Von diesem Ende 15 ausgehend ist der Streifen 7 unter Bildung einer nach außen ragenden Schleife 7a zwischen den beiden Papplagen 3 und 4 hindurch zum oberen Begrenzungsrand der Halteplatte 5 geführt. Hier ist der Streifen 7 mit seinem anderen Ende 16 zwischen den beiden Lagen 17 und 18 eines auf dem oberen Begrenzungsrand der Halteplatte aufruhenden Anschlaggliedes 19 mit diesem verbunden. Das Anschlagglied 19 selbst ist über Verbindungsstege 20, welche eine Sollbruchstelle darstellen, im Bereich der Seitenkanten der Halteplatte 5 mit deren Papplagen 3 und 4 verbunden. Im übrigen Bereich ist das Anschlagglied 19 durch einen Trennschnitt 21 vollkommen von der Halteplatte 5 abgetrennt. Der Trennschnitt 21 weist im Mittenbereich der Halteplatte 5 einen bogenförmigen Verlauf auf, wobei sich die Wölbung dieses Bogens zur Einlaßöffnung 2 der Halteplatte 5 hin erstreckt. Anstelle des bogenförmigen Verlaufes kann der Trennschnitt 21 auch einen dachförmigen Verlauf aufweisen, wobei die Dachspitze zur Einlaßöffnung 2 weist.In the embodiment according to FIGS. 3 and 4, the strip 7 is fastened with one end 15 in the area of the lower boundary edge of the holding plate 5 to the one cardboard layer 4, for example glued on. Starting from this end 15, the strip 7 is guided between the two cardboard layers 3 and 4 to form an outwardly projecting loop 7a to the upper boundary edge of the holding plate 5. Here is the strip 7 with its other end 16 between the two layers 17 and 18 resting on the upper boundary edge of the holding plate Stop member 19 connected to this. The stop member 19 itself is connected via connecting webs 20, which represent a predetermined breaking point, in the region of the side edges of the holding plate 5 with its cardboard layers 3 and 4. In the remaining area, the stop member 19 is completely separated from the holding plate 5 by a separating cut 21. The separating cut 21 has an arcuate course in the central region of the holding plate 5, the curvature of this arch extending towards the inlet opening 2 of the holding plate 5. Instead of the curved course, the separating cut 21 can also have a roof-shaped course, the roof tip pointing towards the inlet opening 2.

Im unteren Teil des Randbereiches 6 sind Rastrillen 22 vorgesehen, deren Tiefe sich über eine oder beide Papplagen 3 und 4 erstrecken kann. Beim Einstecken der Halteplatte 5 in eine im Staubraum eines Staubsaugers vorgesehene Führung, verrasten diese Rastrillen 22 mit entsprechenden, an der Führung vorgesehenen Gegenrastelementen. Anstelle oder auch zusätzlich zu diesen Rastrillen 22 können beispielsweise an den Seitenkanten der Halteplatte Rastwarzen 23, wie in FIG 1 gestrichelt angedeutet, vorgesehen werden.In the lower part of the edge area 6, locking grooves 22 are provided, the depth of which can extend over one or both cardboard layers 3 and 4. When the holding plate 5 is inserted into a guide provided in the dust chamber of a vacuum cleaner, these latching grooves 22 latch with corresponding counter-latching elements provided on the guide. Instead of or in addition to these locking grooves 22, locking lugs 23 can be provided, for example, on the side edges of the holding plate, as indicated by dashed lines in FIG. 1.

Durch die feste Ankoppelung des Anschlaggliedes 19 mittels der Verbindungsstege 20 an die Halteplatte 5 wird ein unbeabsichtigtes Hochziehen des Anschlaggliedes 19 und ein dadurch bedingtes Verschließen der Einlaßöffnung 2 verhindert.The fixed coupling of the stop member 19 by means of the connecting webs 20 to the holding plate 5 prevents the stop member 19 from being inadvertently pulled up and thereby closing the inlet opening 2.

Ist der Staubsaugerfilterbeutel 1 mit Schmutz gefüllt und ein Austausch desselben gegen einen neuen Filterbeutel notwendig, wird das Anschlagglied 19 der Halteplatte 5 des gefüllten Staubsaugerfilterbeutels 1 ergriffen und die Halteplatte 5 nach oben aus der Führung herausgezogen. Da die Halteplatte 5 mit ihren Rastelementen in der Führung verrastet ist, muß eine bestimmte Zugkraft auf das Anschlagglied 19 ausgeübt werden, um die Verrastung der Halteplatte 5 zu lösen. Diese Zugkraft reicht aus, um die Verbindungsstege 20 zu zerreißen, so daß das Anschlagglied 19 und damit der Streifen 7 frei nach oben gezogen werden können. Durch dieses Hochziehen des Streifens 7 wird die Deckungsgleichheit des Loches 12 des Streifens 7 mit der Eintrittsöffnung 2 beseitigt und die Einlaßöffnung 2 durch den Streifen 7 überdeckt. Nachdem der Streifen 7 vollkommen gestrafft ist, wird die Halteplatte 5 wegen der zwischen dem einen Ende 15 des Streifens 7 und der Halteplatte 5 bestehenden Verbindung gegen die Verrastung aus der Führung herausgezogen.If the vacuum cleaner filter bag 1 is filled with dirt and an exchange of the same for a new filter bag is necessary, the stop member 19 of the holding plate 5 of the filled vacuum cleaner filter bag 1 is gripped and the holding plate 5 is pulled up out of the guide. Since the holding plate 5 is locked with its locking elements in the guide, a certain tensile force must be exerted on the stop member 19 in order to to release the locking of the holding plate 5. This tensile force is sufficient to tear the connecting webs 20 so that the stop member 19 and thus the strip 7 can be pulled up freely. By pulling up the strip 7, the congruence of the hole 12 of the strip 7 with the inlet opening 2 is eliminated and the inlet opening 2 is covered by the strip 7. After the strip 7 is completely tightened, the holding plate 5 is pulled out of the guide against the latching because of the connection existing between the one end 15 of the strip 7 and the holding plate 5.

Es besteht auch die Möglichkeit, die Zerstörung der Verbindungssstege 20 durch ein Abknicken des Anschlaggliedes 19 zu bewirken. Hierbei ist ein bogen- oder dachförmiger Verlauf des Trennschnittes 21 von Vorteil. Denn durch einen solchen Verlauf ergeben sich beim Abknicken des Anschlaggliedes 19 gegenüber der Halteplatte 5 im Bereich der Verbindungsstege 20 hohe Biegespannungen, die mit Sicherheit zu einem Zerreißen der Verbindungsstege 20 führen.There is also the possibility of causing the connecting webs 20 to be destroyed by kinking the stop member 19. Here, an arcuate or roof-shaped course of the separating cut 21 is advantageous. Because of such a course, when the stop member 19 is bent relative to the holding plate 5 in the region of the connecting webs 20, high bending stresses result which will certainly lead to the connecting webs 20 tearing.

Das Abknicken des Anschlaggliedes kann nach dem Einsetzen eines Staubsaugerfilterbeutels in den Staubsauger beim Schließen des Staubraumdeckels durch an diesem Deckel entsprechend vorgesehene Abknickelemente selbsttätig er folgen.The kinking of the stop member can automatically follow it after inserting a vacuum cleaner filter bag into the vacuum cleaner when closing the dust chamber cover by means of correspondingly provided bend elements on this cover.

Erfolgt die Zerstörung der Verbindungsstege 20 durch ein Abknicken des Anschlaggliedes 19 kann gegebenenfalls auf eine Verrastung der Halteplatte 5 in der Führung verzichtet werden.If the connecting webs 20 are destroyed by kinking the stop member 19, the latching of the holding plate 5 in the guide can optionally be dispensed with.
