Die Erfindung betrifft ein schnell auswechselbares Luftfilter, bei dem der Luftstrom den gefalteten Filterkörper, der innen von einem Stützkörper abgestützt wird, von außen nach innen durchströmt, wobei der Filterinnenraum von einer Seite von einem Deckel abgeschlossen wird und an der anderen Seite mit einer Ring-Dichtung abschließt, über die das Filter auf einen Ansaugstutzen eines Sauggebläses aufgesteckt wird sowie ein Verfahren zur Herstellung des Stützkörpers und Deckels.The invention relates to a quickly exchangeable air filter which the air flow the folded filter body, which is supported on the inside by a support body is flowed through from the outside to the inside, the interior of the filter from one side is closed by a lid and on the other side with a ring seal completes, via which the filter is attached to an intake port of a suction fan as well as a method for producing the support body and cover.
Derartige Luftfilter, wie sie z. B. bei größeren Staubsaugern bzw. Industriestaubsaugern eingesetzt werden, weisen normalerweise einen auf den Stütz- und Filterkörper aufgesetzten Deckel auf, der aus Metall ist und bei welchem ein abklappbarer Handgriff vorhanden ist.Such air filters as they are, for. B. for larger vacuum cleaners or Industrial vacuum cleaners are used, usually have a support on the and the filter body attached lid, which is made of metal and in which a folding handle is available.
Vorteilhaft können sie über den Handgriff mit einer einzigen Bewegung von dem Ansaugstutzen abgezogen werden und ein neuer bzw. gereinigter Filter kann wieder aufgesetzt werden. Nachteilig bei diesen bekannten Filtern ist es aber, daß die Fertigung aufwendig ist, der Deckel aufgrund seiner Fertigung aus Metall ein erhebliches Gewicht aufweist und die Anbringung des Griffes an den Deckel ebenfalls recht aufwendig ist.You can advantageously use the handle with a single movement can be pulled off the intake manifold and a new or cleaned filter can be put back on. However, the disadvantage of these known filters is that the production is complex, the lid due to its manufacture from metal Has considerable weight and also the attachment of the handle to the lid is quite expensive.
Es ist daher Aufgabe der Erfindung, eine Ausbildung eines Luftfilters zu schaffen, welche insbesondere einfach und mit geringem Aufwand zu fertigen ist, wobei die Fertigung vollautomatisch möglich sein soll und wobei das fertige Filter auch hohen Belastungen während des Betriebes gewachsen sein soll, ohne daß das Auswechseln erschwert würde und ohne daß die Filterfunktion beeinträchtigt sein könnte.It is therefore the object of the invention to provide a design for an air filter to create, which can be manufactured in particular easily and with little effort, where the production should be fully automatic and where the finished filter should also be able to cope with high loads during operation without having to be replaced would be made more difficult and without the filter function could be impaired.
Zusammenfassend kann also gesagt werden, daß ein verbessertes Filter geschaffen werden soll, welches besonders günstig zu fertigen und zu handhaben sein soll.In summary, it can be said that an improved filter is to be created, which is particularly cheap to manufacture and handle target.

Vorteilhaft kann der Deckel zur Aufnahme der beim Aufsetzen und Abziehen auftretenden, zum Teil erheblichen Kräfte radial verlaufende Versteifungsrippen aufweisen und der Fuß des Griffes kann in zwei diametral gegenüber angeordneten Rippen münden. Die Kraftüberleitung kann dabei vorteilhaft erfindungsgemäß weiterhin durch innenliegende Verstärkungsansätze verbessert werden.Advantageously, the cover can be used to hold the when putting on and pulling off occurring, sometimes considerable forces radially extending stiffening ribs have and the foot of the handle can be arranged in two diametrically opposite Ribs open. The transfer of forces can advantageously continue according to the invention by internal reinforcement approaches are improved.
Der Griff ist weiterhin zur Vereinfachung der Fertigung vorteilhaft mit dem Deckel einstückig und kann Bogen-oder Knebelform aufweisen.The handle is also advantageous to simplify manufacture in one piece with the cover and can have an arch or toggle shape.
Die umlaufende Dichtung und/oder der Deckel können mit dem Filterkörper und dem Stützkörper vergossen sein bzw.The circumferential seal and / or the cover can be connected to the filter body and the support body to be cast or
alternativ kann zur besonders günstigen Fertigung bei gleichzeitig großer Robustheit der Deckel mit dem Stützkörper einstückig sein und aus Kunststoff bestehen, wobei später der Filterkörper in einer Ringaußennut des Deckels einsteckbar ist. Die umlaufende Dichtung kann dabei nach Fertigung des Deckels mit dem Stützkörper mit dem freien Rand des Stützkörpers und dem später aufgesteckten Filterkörper vergossen werden.alternatively, for particularly cheap production at the same time great robustness of the cover with the support body in one piece and made of plastic exist, later the filter body can be inserted into an outer ring groove of the cover is. The circumferential seal can, after the cover has been manufactured, with the support body encapsulated with the free edge of the support body and the filter body attached later will.
Für den Fachmann überraschend ist bei der letztgenannten Ausführung mit einstückigem Deckel und Stützkörper die Herstellung in einer geteilten Form ohne weiteres möglich, in welcher beim Druckguß die Durchbrüche oder Öffnungen im Filterkörper durch Vorsprünge der Formwandungen ausgebildet werden., so daß die Verwendung einer großen Anzahl von aufwendigen Schiebern entfallen kann.The last-mentioned embodiment is surprising for the person skilled in the art with one-piece cover and support body manufacturing in a split mold easily possible, in which during die casting the breakthroughs or openings in Filter body are formed by projections of the mold walls. So that the Use of a large number of complex slides can be dispensed with.
