Abstract

The filter bag has a mounting plate (10) provided with a number of superimposed layers, incorporating a flow opening (17), selectively closed by a linear slider (4) incorporated in one of the central layers. The movement of the slider is controlled by a cooperating pivot lever (15) with a rounded nose (22) engaging a curved guide surface formed in one of the side edges of the rectangular slider.

Description

Die Erfindung betrifft einen Filterbeutel für einen Staubsauger, mit einer aus mehreren formstabilen Lagen gebildeten Halteplatte, die mit einer Durchströmöffnung versehen ist, wobei in einer mittleren Lage eine von der Kreisform abweichende Durchbrechung vorgesehen ist, in der ein die Durchströmöffnung freigebender und verschließender Schieber beweglich geführt ist.The invention relates to a filter bag for a vacuum cleaner, with a holding plate formed from a plurality of dimensionally stable layers, which is provided with a through-flow opening, an opening deviating from the circular shape being provided in a middle position, in which a slide which opens and closes the through-flow opening is movably guided is.

Der in Frage kommende Filterbeutel ist aus einem luftdurchlässigen Material gefertigt. Zur Festlegung im Staubsaugergehäuse muß die Halteplatte formstabil sein. Sie besteht üblicherweise aus drei Lagen, die aus Pappe gefertigt sind und gegebenenfalls noch aus einer zwischen einer äußeren und der mittleren Lage dazwischengelegten Dichtscheibe aus einem flexiblen Material. Üblicherweise ist die mittlere Lage aus Pappe mit einer von der Kreisform abweichenden Durchbrechung versehen, in der ein Schieber geführt ist. Bei einem bekannten Filterbeutel ist die Durchbrechung bogenförmig in der Weise ausgebildet, daß ein entsprechender, mit einer Durchströmöffnung versehener Schieber um eine feste Achse geschwenkt werden kann. Bei dieser Ausführung kann der Schieber nur mit einem relativ großen Kraftaufwand gedreht werden, da es aufgrund von unvermeidbaren Fertigungstoleranzen zum Verklemmen kommen kann. Außerdem ist der Schieber mit zwei Fingern zu verdrehen, die von beiden Seiten her auf den Drehpunkt der Achse aufgesetzt werden.The filter bag in question is made of an air-permeable material. To hold it in the vacuum cleaner housing, the holding plate must be dimensionally stable. It usually consists of three layers which are made of cardboard and, if appropriate, also of a sealing disc made of a flexible material, which is interposed between an outer and the middle layer. The middle layer of cardboard is usually provided with an opening which differs from the circular shape and in which a slide is guided. In a known filter bag, the opening is arcuate in such a way that a corresponding slide provided with a throughflow opening can be pivoted about a fixed axis. In this embodiment, the slide can only be turned with a relatively large amount of force, since it jams due to unavoidable manufacturing tolerances can come. In addition, the slide can be turned with two fingers, which are placed on the pivot point of the axis from both sides.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Filterbeutel der eingangs genannten Art in einfacher Weise so auszubilden, daß die Bewegung des Schiebers mit geringerem Kraftaufwand erfolgen kann.The present invention has for its object to provide a filter bag of the type mentioned in a simple manner so that the movement of the slide can be done with less effort.

Gemäß einem ersten Erfindungsvorschlag ist vorgesehen, daß der Schieber als Linearschieber ausgebildet ist, der mittels eines nicht verbundenen, jedoch formschlüssig darin eingreifenden Schwenkhebels von einer die Durchströmöffnung freigebende Öffnungsstellung in eine die Durchströmöffnung abdeckende Verschlußstellung verschiebbar ist.According to a first proposal of the invention, it is provided that the slide is designed as a linear slide which, by means of a non-connected but positively engaging swivel lever, can be displaced from an open position that opens the throughflow opening into a closed position covering the throughflow opening.

Da nunmehr der Linearschieber längs einer Geradlinienbahn verschoben wird, ist das Verecken und Verkanten während der Verschiebebewegung auszuschließen. Da die Schubkraft nunmehr über den Hebel aufgebracht wird, verringert sich das von den beiden Fingern aufzubringende Drehmoment entsprechend der Größe des Hebelarms. Da der Schwenkhebel nicht mit dem Linearschieber verbunden ist, wird eine besonders einfache Konstruktion erreicht. Dabei ist es dann zweckmäßig, wenn der Linearschieber eine viereckige Grundkontur aufweist, wobei die dem Schwenkhebel abgewandte Führungskante und die dazu rechtwinklig stehenden Kanten geradlinig verlaufen. Dabei können die Ecken als Bogen ausgebildet sein.Since the linear slide is now shifted along a straight line path, it cannot be hidden or tilted during the shifting movement. Since the thrust is now applied via the lever, the torque to be applied by the two fingers is reduced in accordance with the size of the lever arm. Since the swivel lever is not connected to the linear slide, a particularly simple construction is achieved. It is then expedient if the linear slide has a square basic contour, the leading edge facing away from the pivoting lever and the edges standing at right angles to it running in a straight line. The corners can be designed as an arc.

Zur Positionierung des Schiebers in der Offenstellung ist vorgesehen, daß eine der in der Offenstellung des Linearschiebers aneinanderstoßenden Kanten des Linearschiebers und der Durchbrechung eine Ausnehmung aufweist, in die eine Führungsnase der anderen Kante eingreift. Dies läßt sich besonders einfach verwirklichen, wenn die Ausnehmung im Linearschieber und die Führungsnase an der die Durchbrechung begrenzenden Kante vorgesehen ist. Der Schwenkhebel kann dabei so ausgebildet sein, daß er als Stütze und Anschlag wirkt. Um dies zu erreichen, ist vorgesehen, daß der Schwenkhebel als flächiges Formteil ausgebildet ist, das an der dem Linearschieber und der Führungsnase zugewandten Seite bzw. Ecke ein in eine konturengerechte Aussparung des Linearschiebers eingreifendes Rundstück vorgesehen ist, und daß an der gegenüberliegenden, dem Linearschieber zugewandten Seite ein freigeschnittener Steg angeordnet ist, dessen dem Hundstück abgewandte Kante gegen eine Kante des Linearschiebers schlägt. Dadurch wird erreicht, daß in der Verschlußstellung des Linearschiebers das Rundstück als Anschlag und der freigeschnittene Steg als Stütze wirkt, wobei beim Überführen des Linearschiebers von der Verschlußstellung in die Öffnungsstellung zunächst der Steg die Linearbewegung hervorruft. Da sich das Rundstück des Schwenkhebels während der Schwenkbewegung auf einem Radius bewegt, ist vorgesehen, daß die konturengerechte Aussparung, in die das Rundstück eingreift, U-förmig ist. Dabei ist die Tiefe so gemessen, daß in der höchsten Stellung des Schwenkhebels das Rundstück am Grund der Aussparung anliegt. Damit zur Lagerung des Schwenkhebels keine zusätzlichen Teile erforderlich werden, ist vorgesehen, daß dieser an der dem Linearschieber abgewandten Seite ein Bogenstück aufweist, dessen Mittelpunkt die Drehachse des Schwenkhebels bildet und daß die Durchbrechung zur Lagerung des Schwenkhebels eine lagegerechte Aussparung aufweist, in die das Bogenstück eingreift. Zur Funktion des Schwenkhebels ist dabei vorgesehen, daß die Drehachse in einem, bezogen auf die Breite des Schwenkhebels geringen Versatz zu dem gegenüberliegenden Steg steht, wobei der Versatz in Richtung zum Rundstück liegt.To position the slide in the open position, it is provided that one of the edges of the linear slide and the opening which abut one another in the open position of the linear slide and the opening has a recess into which a guide lug of the other edge engages. This can be achieved particularly easily if the recess in the linear slide and the guide lug are provided on the edge delimiting the opening. The pivot lever can be designed so that it acts as a support and stop. In order to achieve this, it is provided that the pivot lever is designed as a flat molded part which, on the side or corner facing the linear slide and the guide lug, is provided with a round piece which engages in a contour-appropriate recess of the linear slide, and that on the opposite, the linear slide a cut-away web is arranged, the edge of which faces away from the dog piece strikes an edge of the linear slide. It is thereby achieved that in the closed position of the linear slide the round piece acts as a stop and the cut-open web acts as a support, the web moving the linear movement first when the linear slide is transferred from the closed position into the open position evokes. Since the round piece of the swivel lever moves on a radius during the swivel movement, it is provided that the contour-appropriate recess into which the round piece engages is U-shaped. The depth is measured so that in the highest position of the pivot lever, the round piece rests against the bottom of the recess. So that no additional parts are required for mounting the swivel lever, it is provided that it has a curved piece on the side facing away from the linear slide, the center of which forms the axis of rotation of the swivel lever and that the opening for mounting the swivel lever has a position-correct recess into which the curved piece intervenes. For the function of the swivel lever, it is provided that the axis of rotation is at a slight offset relative to the opposite web relative to the width of the swivel lever, the offset being in the direction of the round piece.

Gemäß einem zweiten Erfindungsvorschlag ist vorgesehen, daß der Schieber als Drehschieber ausgebildet ist und einen gegenüber der zugeordneten Kante der Halteplatte vorstehenden Schwenkhebel aufweist. Das freie, von den Fingern zu ergreifende Ende des Schwenkhebels liegt außerhalb der Halteplatte, und der Drehpunkt innerhalb der Halteplatte. Dadurch wird die aufzubringende Kraft herabgesetzt, bedingt durch die Hebelwirkung. Zweckmäßigerweise sind der Schieber und der Schwenkhebel als einstückiges Formteil ausgebildet. In weiterer Ausgestaltung dieses Vorschlages ist vorgesehen, daß der Drehschieber in seiner Außenkontur einen Kreisbogen aufweist, der in der Offenstellung fluchtend zum zugeordneten Rand der Durchströmöffnung steht. Dadurch entfällt eine zusätzliche Bohrung innerhalb der Kontur des Drehschiebers. Um Material einzusparen ist vorgesehen, daß zumindest der Linearschieber aus dem Stanzling der Durchbrechung gefertigt ist. Ferner ist es bei allen Ausführungen besonders vorteilhaft, wenn die Haltepappe aus drei Lagen gebildet ist. Die drei Lagen können durch Faltung eines entsprechenden Zuschnittes gebildet werden.According to a second proposal of the invention, it is provided that the slide is designed as a rotary slide and has a pivoting lever which projects from the associated edge of the holding plate. The free end of the pivot lever to be gripped by the fingers lies outside the holding plate, and the fulcrum inside the holding plate. As a result, the force to be applied is reduced due to the leverage effect. The slide and the swivel lever are expediently designed as a one-piece molded part. In a further embodiment of this proposal it is provided that the rotary slide valve has a circular arc in its outer contour, which in the open position is aligned with the associated edge of the throughflow opening. This eliminates the need for an additional hole within the contour of the rotary valve. In order to save material, it is provided that at least the linear slide is made from the die cut of the opening. Furthermore, it is particularly advantageous in all versions if the holding cardboard is formed from three layers. The three layers can be formed by folding an appropriate blank.

Anhand der beiliegenden Zeichnungen wird die Erfindung noch näher erläutert.The invention is explained in more detail with reference to the accompanying drawings.

Gemäß der Darstellung nach der Figur 1 besteht die Halteplatte 10 aus zwei äußeren, aus Pappe gefertigen Lagen 11, 12, einer mittleren Lage 13, einem Linearschieber 14, einem Schwenkhebel 15 und einer Dichtlage 16. Die Lagen 11 bis 13 werden in nicht näher dargestellter Weise durch Klebung miteinander verbunden. Die beiden äußeren Lagen 11, 12, die mittlere Lage 13, der Linearschieber 14 und die Dichtlage sind mit kreisrunden Bohrungen versehen, die fluchtend zueinander angeordnet sind, so daß in der Offenstellung des Linearschiebers 14 eine Durchströmöffnung 17 entsteht. Der Durchmesser in der Bohrung der Dichtlage 16 ist kleiner als der in den anderen Lagen, so daß bei der fertigen Halteplatte 10 ein in die Durchströmöffnung 17 hineinragender Dichtring 18 gebildet ist. Die mittlere Lage 13 ist mit einer von der Kreisform abweichenden Durchbrechung 19 versehen, in die der Linearschieber 14 und der Schwenkhebel 15 eingesetzt sind. Aus der Figur 1 ergibt sich, daß der Linearschieber 14 und der Schwenkhebel 15 aus dem Stanzling gefertigt sind, der durch Ausstanzen der Durchbrechung 19 entsteht. Der Linearschieber 14 ist in seiner Grundkontur viereckig, wobei die in der Darstellung obere linke Ecke in einem Bogen verläuft. Die den Linearschieber 14 in der Offenstellung kontaktierende Querkante ist mit einer Führungsnase 20 versehen, die in der Offenstellung des Linearschiebers 14 in eine entsprechend gestaltete Durchbrechung 21 eingreift. Der Schwenkhebel 15 ist an der der Durchbrechung 21 zugewandten Seite mit einem Rundstück 22 versehen, welches in eine U-förmige Aussparung 23 des Linearschiebers 14 eingreift. Der Linearschieber 14 ist an der dem Rundstück 22 gegenüberliegenden Seite mit einem freigeschnittenen Steg 24 versehen, der in der Offenstellung des Linearschiebers 14 gegen eine durch einen Ausschnitt gebildete Kante 25 schlägt. Zur Lagerung des Schwenkhebels 15 ist dieser an der dem Rundstück 22 und dem Steg 24 gegenüberliegenden Seite mit einem Bogenstück 26 versehen, welches in eine entsprechend kreisförmig ausgebildete Aussparung 27 der Durchbrechung 19 eingreift. Das Bogenstück 26 ist mit einer kreuzförmigen Ausstanzung versehen, damit es zum Verschwenken des Schwenkhebels 15 griffiger wird. Damit das Bogenstück 26 zwischen zwei Finger festgeklemmt werden kann, sind die beiden äußeren Lagen 11, 12 mit zwei entsprechenden Bohrungen 28 versehen. Die zwischen der Aussparung 27 und der Führungsnase 20 verlaufende Fläche 19a der Durchbrechung 19 ist als Schrägfläche ausgebildet, die in Richtung zur Führungsnase 20 ansteigt.1, the holding plate 10 consists of two outer layers 11, 12 made of cardboard, a middle layer 13, a linear slide 14, a pivoting lever 15 and a sealing layer 16. The layers 11 to 13 are not shown in more detail Way connected by gluing. The two outer layers 11, 12, the middle layer 13, the linear slide 14 and the sealing layer are provided with circular bores which are arranged in alignment with one another, so that a throughflow opening 17 is formed in the open position of the linear slide 14. The diameter in the bore of the sealing layer 16 is smaller than that in the other layers, so that a sealing ring 18 protruding into the throughflow opening 17 is formed in the finished holding plate 10. The middle layer 13 is provided with an opening 19 deviating from the circular shape, into which the linear slide 14 and the pivoting lever 15 are inserted. It can be seen from FIG. 1 that the linear slide 14 and the pivoting lever 15 are made from the punched part which is produced by punching out the opening 19. The linear slide 14 is square in its basic contour, the upper left corner in the illustration running in an arc. The transverse edge contacting the linear slide 14 in the open position is provided with a guide lug 20 which engages in a correspondingly designed opening 21 in the open position of the linear slide 14. The pivot lever 15 is provided on the side facing the opening 21 with a round piece 22 which engages in a U-shaped recess 23 of the linear slide 14. The linear slide 14 is provided on the side opposite the round piece 22 with a cut-free web 24 which, in the open position of the linear slide 14, strikes against an edge 25 formed by a cutout. To mount the pivot lever 15, this is provided on the side opposite the round piece 22 and the web 24 with an arc piece 26 which engages in a correspondingly circular recess 27 in the opening 19. The bow piece 26 is provided with a cross-shaped punching so that it can be pivoted of the pivot lever 15 is grippier. So that the arch piece 26 can be clamped between two fingers, the two outer layers 11, 12 are provided with two corresponding bores 28. The surface 19a of the opening 19 running between the recess 27 and the guide lug 20 is designed as an inclined surface which rises in the direction of the guide lug 20.

Insbesondere die Figuren 2 und 3 zeigen, daß in der Verschlußstellung des Linearschiebers 14 gemäß der Figur 2 der Linearschieber 14 durch die Führungnase 20 und den Steg 24 in der Position gehalten werden. Wird der Schwenkhebel 15 im Uhrzeigersinn in die Offenstellung gemäß der Figur 3 geschwenkt, erfolgt die Schubbewegung zunächst ausschließlich durch den Steg 24. Ab einer gewissen Stellung erfolgt dann die Schubbewegung durch das Rundstück 22, welches sich in der Aussparung 23 abwälzt. Wenn das Rundstück 22 die höchste Stellung erreicht hat, liegt es an der den Grund der Aussparung 23 bildenden Kante an. Bei dem in den Figuren 1 bis 3 dargestellten Ausführungsbeispiel besteht die Halteplatte 10 aus drei einzelnen Lagen 11 bis 13. Im Gegensatz dazu könnte die Halteplatte 10 auch aus einem einstückigen Zuschnitt entsprechend der Figur 4 gefaltet werden, wenn die Durchbrechung 19 entsprechend gestaltet wird. Das in den Figuren 4 bis 6 dargestellte Ausführungsbeispiel beinhaltet wiederum die beiden äußeren Lagen 11 und 12 sowie die mittlere Lage 13, die mit einer Durchbrechung 19 versehen ist. Der Schieber ist als Drehschieber 29 ausgebildet, an dem ein Schwenkhebel 30 angesetzt ist, der gegenüber der zugeordneten Kante der Halteplatte 10 vorsteht, so daß er zum Überführen von der in der Figur 5 dargestellten Offenstellung in die in der Figur 6 dargestellte Verschlußstellung ergriffen werden kann. Von der Wirkung her ist der Drehschieber 29 mit dem Schwenkhebel 30 wie ein zweiarmiger Hebel zu sehen. Der Drehschieber 29 ist um eine Achse 31 schwenkbar, die in einem geringen Abstand zur zugeordneten Kante der Halteplatte 10 liegt.FIGS. 2 and 3 in particular show that in the closed position of the linear slide 14 according to FIG. 2, the linear slide 14 is held in position by the guide lug 20 and the web 24. If the pivoting lever 15 is pivoted clockwise into the open position according to FIG. 3, the pushing movement initially takes place exclusively through the web 24. From a certain position, the pushing movement then takes place through the round piece 22, which rolls in the recess 23. When the round piece 22 has reached the highest position, it bears against the edge forming the base of the recess 23. In the embodiment shown in Figures 1 to 3, the holding plate 10 consists of three individual layers 11 to 13. In contrast, the holding plate 10 could also be folded from a one-piece blank according to Figure 4, if the opening 19 is designed accordingly. The exemplary embodiment shown in FIGS. 4 to 6 again includes the two outer layers 11 and 12 and the middle layer 13, which is provided with an opening 19. The slide is designed as a rotary slide 29, on which a pivot lever 30 is attached, which protrudes relative to the associated edge of the holding plate 10, so that it can be gripped for transferring from the open position shown in FIG. 5 to the closed position shown in FIG . In effect, the rotary valve 29 can be seen with the pivot lever 30 like a two-armed lever. The rotary slide 29 is pivotable about an axis 31 which is at a short distance from the associated edge of the holding plate 10.

In der Figur 4 ist aus Darstellungsgründen die Dichtlage 16 nicht dargestellt. Aus den Figuren 4 und 5 ergibt sich, daß die Außenkontur des Drehschiebers 29 einen Kreisbogen 32 aufweist, der in der Offenstellung gemäß der Figur 5 fluchtend zur Durchströmöffnung 17 steht. Der Drehschieber 29 ist so ausgelegt, daß er in der Verschlußstellung die Durchströmöffnung 17 abdeckt. Damit der Schwenkhebel 30 nicht extrem gegenüber der zugeordneten Kante der Halteplatte 10 vorsteht, ist der Verbindungsbereich zwischen der Lage 11 und 12 mit einer etwa kreisförmigen Ausstanzung 33 versehen, so daß im zusammengefalteten Zustand diese Kante nach innen, d. h. in Richtung zur Achse 31 verspringt. Zur Erleichterung des Faltvorganges schließt sich an die Ausstanzung 33 noch ein Schlitz 34 an, der jedoch nicht bis zur Seitenkante geführt ist.For the sake of illustration, the sealing layer 16 is not shown in FIG. It can be seen from FIGS. 4 and 5 that the outer contour of the rotary valve 29 has an arc 32 which, in the open position according to FIG. 5, is aligned with the throughflow opening 17. The rotary valve 29 is designed so that it covers the flow opening 17 in the closed position. So that the pivot lever 30 does not protrude extremely from the associated edge of the holding plate 10, the connection area between the layers 11 and 12 is provided with an approximately circular punched-out 33, so that in the folded state this edge jumps inwards, ie in the direction of the axis 31. To facilitate the folding process is followed by a slot 34 on the punched-out 33, which, however, is not guided to the side edge.
