- the shutter can be opened during operation of the vacuum cleaner filter bag.
- opening the shutter moves towards the interior of the vacuum cleaner filter bag.
- the opening of the closure flap can be effected in particular by means of the suction air flow; when the vacuum cleaner is turned off, the shutter closes automatically again due to the spring force.
- the holding plate further has a sealing lip 8 at its passage opening 2.
- This sealing lip 8 can be arranged in particular surrounding the passage opening 2 on the base plate 4.
- the sealing lip serves to seal a nozzle, which in the passage opening 2 is guided and passes through the in operation of the vacuum cleaner filter bag sucked air into the vacuum cleaner filter bag.
- the base plate 4 and the closure flaps 3 with the areas 5 and 6 are preferably made of plastic.

- the second material of this second region is made relatively thin. The thickness is less than 1 mm and preferably between 0.05 mm and 0.9 mm.
- the hardness of the second material is preferably between 30 and 60 Shore-A.
- the thin and soft edge region 6 allows easy pivoting of the closure flap 3.
- this second region is easily bent and thus allows the closure flap to be closed even when the bag is heavily filled trained filter cake can be easily opened and closed. If, in addition dust particles should be present in the region of the passage opening, the flexible second region will deform at the appropriate location, but otherwise does not prevent closing the flap.
- the first region 5 of the closure flap 3 does not extend to the edge 12 of the passage opening 2; the first region 5 thus has a smaller area than that of the passage opening 2.
- the second area 6, however, projects beyond the first area 5 and also beyond the edge 12 of the passage opening 2; it extends over the base plate. This ensures a reliable closing of the passage opening 2.
- the second region 6 projects beyond the first region 5 by at least 3 mm.
- the second material is, for example, a thermoplastic elastomer, such as an elastomer-modified polypropylene.
- the second material may be from another Be made of plastic; other options are the use of a rubber film, a nonwoven fabric or paper.
- the second material may be welded or glued to the first material.
- the holding plate may be made with the closure plate in a two-component injection molding process in which the second material is molded onto the first material.
- the second region can be formed flat and arranged in a plane parallel to the plane of the first region.
- the second material on the other hand, is inclined away from the first material in the direction of the passage opening. Such profiling improves the dust-tight sealing of the passage opening.
- the first and second regions can be formed in various ways. Examples are in the FIGS. 3 to 5 shown. These are in each case plan views of the closure flap from the interior of the vacuum cleaner filter bag.
- the second material is in each case attached in the closing direction of the closure flap behind the first material to this. In principle, however, it is also possible that the second material is arranged on the other side of the closure flap.
- the first region 5 is circular, as indicated by dashed lines.
- the first region 5 integrally formed with the base plate 4 and connected via a film hinge with this.
- the flexible edge region 6 is provided in the form of a part of a circular ring. This flexible region 6 overlaps on the one hand with the first region 5 where it is glued to it, and on the other hand, in the closed state of the closure flap, with the passage opening. In particular, the flexible edge element 6 extends over the (dashed lines shown) edge 12 of the passage opening. With the exception of the hinge region, here the second region 6 is provided along the entire circumference of the closure flap.
- the area of the first area 5 is less than the area of the passage opening defined by the peripheral edge 12. Furthermore, the edge of the first area except the hinge area in the closed position is completely spaced from the edge 12 of the passage opening.
- the base plate 4 of the retaining plate is welded along the weld 13 with the bag wall 11 of the vacuum cleaner filter bag.
- the second area 6 comprises three circle segments, which are fastened to a T-shaped first area 5.
- the majority of the surface of the flap is formed here by the second material.
- the surface of the first region 5 is indeed smaller than the area defined by the peripheral edge 12 of the passage opening.
- the area 5 with its crossbar extends to the edge 12 and rests on this.
- FIG. 5 example shown corresponds to the example in FIG. 3 , wherein the second region now has a plurality of sections separated by slots 9.
- the sections have the advantage that, in spite of a dirt particle trapped between the second material and the edge of the passage opening, a good sealing of the passage opening can be achieved when the closure flap is closed.
- FIG. 6 again shows a plan view of a retaining flap seen from the interior of a vacuum cleaner filter bag.
- the second material has been omitted for illustrative purposes.
- the first region 5 is designed predominantly circular. How one FIG. 6 can also be here, the area of the first region 5 is less than that of the defined by the edge 12 surface of the passage opening 2.
- the second region 5 does not protrude to two radially disposed webs 10 to the edge of the passage opening second
- first area 5 can now be a second, softer material, for example, as in Figures 3 or 5 shown to be attached.
- the webs 10 and the second material could be partially thickened (for example, in web form) to ensure a corresponding concern to the edge of the passage opening.
- the first area 5 (except for the hinge area) would not have to reach the edge of the passage opening 2.
- the bias of the spring 7 can be dispensed both on the webs on the first material and thickening in the second material.
- two webs may alternatively be provided only a web or a larger number of webs.
- closure flap only one closure flap is provided in each case.
- the features described can also be applied to the case of two or more partial flaps, as used for example in the DE 20 2008 04 733 are shown.
- Each of the partial flaps would then be provided with the second material, which is arranged in particular in the region where the partial flaps touch in the closed position.
Abstract
Description
Die Erfindung betrifft eine Halteplatte für einen Staubsaugerfilterbeutel mit einer Verschlussklappe.The invention relates to a holding plate for a vacuum cleaner filter bag with a closure flap.
Staubsaugerfilterbeutel weisen üblicherweise an der Eintrittsöffnung in den Beutel eine Halteplatte auf, die zum Haltern des Filterbeutels im Inneren eines Staubsaugers vorgesehen ist. Die Öffnungen in diesen Halteplatten sind häufig mittels einer Verschlusskappe verschließbar. Im Saugbetrieb befindet sich die Verschlussklappe in einer Offenstellung, in der die Durchtrittsöffnung der Halteplatte geöffnet ist. Bei Beendigung des Saugbetriebs schließt sich die Verschlussklappe.Vacuum cleaner filter bags usually have at the inlet opening in the bag on a holding plate, which is provided for holding the filter bag inside a vacuum cleaner. The openings in these holding plates are often closed by means of a closure cap. In suction, the closure flap is in an open position in which the passage opening of the holding plate is open. Upon completion of the suction operation, the shutter closes.
Herkömmliche Halteplatten sind beispielsweise aus der
Derartige herkömmliche Halteplatten haben den Nachteil, dass sich im Bereich der Öffnung der Halteplatte Staubteilchen oder Fasern ablagern. Dabei können sich insbesondere auch am Rand der Öffnung grobe Staubpartikel oder Fasern befinden und ein vollständiges Verschließen durch die Verschlussklappe verhindern.Such conventional holding plates have the disadvantage that deposit dust particles or fibers in the region of the opening of the holding plate. In this case, coarse dust particles or fibers can also be located at the edge of the opening and prevent complete closure by the closure flap.
Angesichts dieser Problematik sind verschiedene Möglichkeiten vorgeschlagen worden, die Staubsaugerfilterbeutel zu verbessern. In der
Die
Angesichts des Stands der Technik besteht Bedarf an einer weiter verbesserten Halteplatte für einen Staubsaugerfilterbeutel mit einer Verschlussklappe, die möglichst auch bei stärker gefülltem Beutel ein Verschließen der Halteklappenöffnung ermöglicht. Hierfür stellte die Erfindung eine Halteplatte gemäß Anspruch 1 bereit.In view of the state of the art, there is a need for a further improved holding plate for a vacuum cleaner filter bag with a closure flap, which makes it possible to close the holding flap opening even if the bag is more heavily filled. For this purpose, the invention provided a holding plate according to claim 1.
Erfindungsgemäß wird eine Halteplatte für einen Staubsaugerfilterbeutel bereitgestellt, umfassend eine Durchtrittsöffnung und eine Verschlussklappe zum Verschließen der Durchtrittsöffnung, wobei die Verschlussklappe einen ersten Bereich umfassend ein erstes Material mit einer ersten Härte und einen zweiten Bereich umfassend ein zweites Material mit einer zweiten Härte umfasst, wobei die zweite Härte geringer als die erste Härte ist, wobei der zweite Bereich zumindest teilweise im Rand der Verschlussklappe angeordnet ist, und wobei des zweite Material zumindest teilweise eine Dicke von weniger als 1 mm aufweist.According to the invention, a holding plate is provided for a vacuum cleaner filter bag, comprising a passage opening and a closure flap for closing the passage opening, wherein the closure flap comprises a first area comprising a first material having a first hardness and a second area comprising a second material having a second hardness second hardness is less than the first hardness, wherein the second region is at least partially disposed in the edge of the closure flap, and wherein the second material at least partially has a thickness of less than 1 mm.
Da das weichere Material in einem Randbereich der Verschlussklappe eine geringe Dicke von weniger als 1 mm aufweist, kann sich die Verschlussklappe beispielsweise bei einem stärker schmutzgefüllten Beutel immer noch durch den sich gebildeten Filterkuchen bewegen, insbesondere weil sich der weiche und dünne Rand leicht biegen lässt. Ein sicheres Verschließen wird somit gewährleistet.For example, because the softer material has a small thickness of less than 1 mm in an edge region of the closure flap, the closure flap may still move through the formed filter cake in a more heavily-filled bag, particularly because the soft and thin edge is easily deflected. A secure closure is thus ensured.
Die Materialhärten können beispielsweisweise Shore-Härten sein. Die Halteplatte ist zum Haltern des Staubsaugerfilterbeutels im Innern eines Staubsaugers ausgebildet. Die Halteplatte kann insbesondere eine Grundplatte umfassen, in der die Durchtrittsöffnung ausgebildet ist. Diese Grundplatte kann aus einem Kunststoff sein. Die Verschlussklappe kann an der Grundplatte angeschlagen sein. Die Verschlussklappe kann über ein Scharnier, beispielsweise ein Filmscharnier, mit der Grundplatte verbunden sein.The material hardnesses can be, for example, shore hardnesses. The holding plate is designed to hold the vacuum cleaner filter bag inside a vacuum cleaner. The retaining plate may in particular comprise a base plate in which the passage opening is formed. This base plate can be made of a plastic. The flap may be hinged to the base plate. The closure flap can be connected to the base plate via a hinge, for example a film hinge.

Das erste und/oder das zweite Material können ein Kunststoff sein. Dabei können das erste Material ein Thermoplast und/oder das zweite Material ein Elastomer sein. Bei dem zweiten Material kann es sich beispielsweise um ein thermoplastisches Elastomer (TPE) handeln. Das TPE kann olefinbasiert (TPE-O), vernetzt olefinbasiert (TPE-V), urethanbasiert (TPE-U), ein Styrol-Blockcopolymer (TPE-S) oder ein Copolyamid (TPE-A) sein. Dies ermöglicht eine einfache Herstellung der Halteplatte. Das zweite Material kann insbesondere ein elastomer-modifiziertes Polypropylen sein. Das zweite Material kann in Form einer Folie ausgebildet sein.The first and / or the second material may be a plastic. In this case, the first material may be a thermoplastic and / or the second material may be an elastomer. The second material may be, for example, a thermoplastic elastomer (TPE). The TPE can be olefin-based (TPE-O), crosslinked olefin-based (TPE-V), urethane-based (TPE-U), a styrene block copolymer (TPE-S) or a copolyamide (TPE-A). this makes possible a simple production of the holding plate. The second material may in particular be an elastomer-modified polypropylene. The second material may be in the form of a film.
Das zweite Material kann eine Härte von 25 bis 70 Shore-A, vorzugsweise von wenigstens 30 Shore-A und/oder höchstens 60 Shore-A aufweisen.

Bevorzugt kann es zumindest teilweise oder überall eine Dicke von 0,02 mm bis 0,9 mm, insbesondere von 0,05 bis 0,2 mm, weiter bevorzugt von 0,1 bis 0,2 mm aufweisen. Insbesondere wenn das zweite Material nur teilweise in den angegebenen Dickenintervalle liegt, kann der außerhalb dieser Dickenintervalle liegende Bereich höchstens 20 %, vorzugsweise höchstens 10 % der Fläche des zweiten Bereichs sein. So kann beispielsweise höchstens 20 % der Fläche des zweiten Bereichs eine Dicke von 1 mm oder mehr aufweisen.The second material may in particular not only partially, but everywhere have a thickness of less than 1 mm. It may preferably have a thickness of 0.02 mm to 0.9 mm, in particular from 0.05 to 0.2 mm, more preferably from 0.1 to 0.2 mm, at least partially or everywhere. In particular, if the second material is only partially within the stated thickness intervals, the area lying outside of these thickness intervals may be at most 20%, preferably at most 10%, of the area of the second area. For example, at most 20% of the area of the second area may have a thickness of 1 mm or more.

The first region may overlap at least partially with the second region. The area of the first area may in particular comprise at most 90%, preferably at most 80% of the area of the passage opening. If a sealing lip is additionally provided at the passage opening, the first area can also have a correspondingly smaller area than the area of the passage opening of the sealing lip.
Bei den zuvor beschriebenen Halteplatten kann der zweite Bereich zumindest teilweise entlang des Umfangs oder Randes der Verschlussklappe vorgesehen sein. Dabei können insbesondere wenigstens 50 %, bevorzugt wenigstens 70 %, weiter bevorzugt wenigstens 90 % des Umfangs der Verschlusskappe durch das zweite Material gebildet sein.

Der zweite Bereich kann bei geschlossener Durchtrittsöffnung (also in Verschlussstellung der Verschlussklappe) über den Rand der Durchtrittsöffnung ragen. Der zweite Bereich kann derart ausgebildet sein, dass er bei geschlossener Durchtrittsöffnung zumindest teilweise auf der Grundplatte der Halteplatte aufliegt. Die Fläche der Verschlussklappe kann größer als die der Durchtrittsöffnung sein.The second region can protrude beyond the edge of the passage opening when the passage opening is closed (ie in the closed position of the shutter). The second region may be formed such that it rests at least partially on the base plate of the holding plate when the passage opening is closed. The surface of the closure flap may be larger than that of the passage opening.
Der Rand des ersten Bereichs kann in der Verschlussstellung der Verschlussklappe zumindest teilweise vom Rand der Durchtrittsöffnung beabstandet sein. Der Rand des ersten Bereichs kann insbesondere mit Ausnahme des Scharniers oder Scharnierbereichs in Verschlussstellung vollständig vom Rand der Durchtrittsöffnung beabstandet sein.The edge of the first region may be at least partially spaced from the edge of the passage opening in the closed position of the closure flap. The edge of the first region can be completely spaced from the edge of the passage opening, in particular with the exception of the hinge or hinge region in the closed position.
Der zweite Bereich kann eine Mehrzahl von durch Schlitze getrennte Abschnitte aufweisen. Die Schlitze können insbesondere in radialer Richtung verlaufen. Die Schlitze können insbesondere über die gesamte Breite ausgebildet sein, um die der zweite Bereich über den ersten Bereich hinausragt. Die Schlitze können entlang des Umfangs der Verschlussklappe um wenigstens 1 mm vorzugsweise wenigstens 3 mm, weiter bevorzugt wenigstens 5 mm voneinander beabstandet sein.The second region may have a plurality of slit-separated portions. The slots can extend in particular in the radial direction. The slots may in particular be formed over the entire width by which the second area projects beyond the first area. The slots may be spaced apart along the perimeter of the closure flap by at least 1 mm, preferably at least 3 mm, more preferably at least 5 mm.
Das zweite Material kann in Schließrichtung der Verschlussklappe vor oder hinter dem ersten Material an diesem befestigt sein. Das erste und das zweite Material können miteinander verklebt oder miteinander verschweißt sein. Alternativ können der erste und der zweite Bereich (bzw. das erste und das zweite Material) mittels eines Zwei-Komponenten-Spritzgießverfahrens hergestellt sein.The second material may be fastened in the closing direction of the closure flap in front of or behind the first material. The first and second materials may be glued together or welded together. Alternatively, the first and second regions (or first and second materials) may be made by a two-component injection molding process.
Der zweite Bereich kann bei geöffneter Stellung der Verschlussklappe plan oder nicht-plan ausgebildet sein. Er kann bei geöffneter Stellung insbesondere profiliert, beispielsweise schüsselförmig profiliert, ausgebildet sein. Das zweite Material kann bei geöffneter Stellung zumindest teilweise in Richtung der Durchtrittsöffnung (also in Schließrichtung) geneigt oder gebogen sein.The second area may be formed plan or non-planar in the open position of the flap. It can in particular profiled in the open position, for example, profiled bowl-shaped, be formed. The second material may be at least partially inclined or bent in the open position in the direction of the passage opening (ie in the closing direction).

Die Verschlussklappe 3 ist über ein Scharnier mit der Grundplatte 4 der Halteplatte 1 verbunden. Die Verschlussklappe 3 umfasst einen ersten Bereich 5 aus einem ersten Material sowie einen zweiten Bereich 6 aus einem zweiten Material. Die Grundplatte 4 der Halteplatte 1 ist mit der Beutelwandung 11 des Staubsaugerfilterbeutels verbunden, beispielsweise verschweißt.The
Die Halteplatte weist weiterhin eine Feder 7 auf, mittels der die Verschlussklappe in die Verschlussstellung vorgespannt ist. Diese Feder ist im gezeigten Beispiel auf ihrer einen Seite an der Verschlussklappe fest befestigt, kann sich allerdings auf der andere Seite entlang der Grundplatte 4 bewegen.The retaining plate further comprises a
Wie in
Die Halteplatte weist an ihrer Durchtrittsöffnung 2 weiterhin eine Dichtlippe 8 auf. Diese Dichtlippe 8 kann insbesondere die Durchtrittsöffnung 2 umgebend an der Grundplatte 4 angeordnet sein. Die Dichtlippe dient der Abdichtung eines Stutzens, der in die Durchtrittsöffnung 2 geführt wird und durch den in Betrieb des Staubsaugerfilterbeutel die angesaugte Luft in den Staubsaugerfilterbeutel tritt.The holding plate further has a sealing
Die Grundplatte 4 sowie die Verschlussklappen 3 mit den Bereichen 5 und 6 sind vorzugsweise aus Kunststoff. Insbesondere die Grundplatte sowie der erste Bereich 5 der Verschlussplatte können aus dem gleichen Material sein; sie können insbesondere einstückig (beispielsweise mittels eine Spritzgießverfahrens) ausgebildet sein. Das Scharnier ist als Filmscharnier in dem Kunststoff ausgebildet.The
Das Material der Grundplatte 4 sowie des ersten Bereichs 5 kann beispielsweise ein Polypropylen mit einer geeigneten Härte (bspw. 70 Shore-D) sein, um den an der Halteplatte befestigten Staubsaugerfilterbeutel im Inneren eines Staubsaugers zu haltern. Die Verschlussklappe 3 weist neben dem ersten Bereich 5 einen zweiten Bereich 6 auf, der eine geringere Härte aufweist. Das zweite Material dieses zweiten Bereichs ist verhältnismäßig dünn ausgeführt. Die Dicke liegt unter 1 mm und bevorzugterweise zwischen 0,05 mm und 0,9 mm. Die Härte des zweiten Material liegt vorzugsweise zwischen 30 und 60 Shore-A.The material of the
Wenn sich die Verschlussklappe 3 im Betrieb des Staubsaugerfilterbeutels öffnet oder schließt, ermöglicht der dünne und weiche Randbereich 6 ein einfaches Schwenken der Verschlussklappe 3. Insbesondere lässt sich dieser zweite Bereich leicht biegen und ermöglicht es somit, dass die Verschlussklappe auch bei stark befüllten Beutel und entsprechend ausgebildeten Filterkuchen leicht geöffnet und geschlossen werden kann. Falls zusätzlich Staubpartikel im Bereich der Durchtrittsöffnung vorhanden sein sollten, wird sich der flexible zweite Bereich an der entsprechenden Stelle verformen, was aber ansonsten ein Schließen der Verschlussklappe nicht verhindert.When the

Das zweite Material ist beispielsweise ein thermoplastisches Elastomer, wie ein elastomer-modifiziertes Polypropylen. Alternativ kann das zweite Material auch aus einem anderen Kunststoff hergestellt sein; weitere Möglichkeiten sind die Verwendung einer Gummifolie, eines Vliesstoffs oder von Papier. Das zweite Material kann mit dem ersten Material verschweißt oder verklebt sein. Alternativ kann die Halteplatte mit der Verschlussplatte in einem Zwei-Komponenten-Spritzgießverfahren hergestellt werden, bei dem das zweite Material an das erste Material angespritzt wird.The second material is, for example, a thermoplastic elastomer, such as an elastomer-modified polypropylene. Alternatively, the second material may be from another Be made of plastic; other options are the use of a rubber film, a nonwoven fabric or paper. The second material may be welded or glued to the first material. Alternatively, the holding plate may be made with the closure plate in a two-component injection molding process in which the second material is molded onto the first material.

Entlang des Umfangs des ersten Bereichs 5 ist der flexible Randbereich 6 in Form eines Teils eines Kreisringes vorgesehen. Dieser flexible Bereich 6 überlappt einerseits mit dem ersten Bereich 5, wo er mit diesem verklebt ist, und andererseits, im geschlossenen Zustand der Verschlussklappe, mit der Durchtrittsöffnung. Insbesondere erstreckt sich das flexible Randelement 6 über den (strichliert gezeigten) Rand 12 der Durchtrittsöffnung. Mit Ausnahmen des Scharnierbereichs ist hier der zweite Bereich 6 entlang des gesamten Umfangs der Verschlussklappe vorgesehen.Along the circumference of the
Bei diesem Beispiel ist die Fläche des ersten Bereichs 5 geringer als die durch den umlaufenden Rand 12 definierte Fläche der Durchtrittsöffnung.
