Luftfiltereinsatz mit angegossenem TragrahmenAir filter insert with cast support frame

Die Neuerling betrifft einen Luftfiltereinsatz mit einem angegossenem Tragrahmen, wobei der Tragrahmen mit seinem Innenumfang einen aus zick-zack-förmig gefaltetem FilterThe newcomer concerns an air filter insert with a cast-on support frame, whereby the support frame with its inner circumference has a filter made of zigzag-shaped folds papier oder -stoff bestehenden Filterkörper an dessen vier Schmalselten in Höhe einer der Flachseiten umfaßt und aus einem hochelastischen Kunststoff besteht und wobei der Luftfiltereinsatz unter randseitiger Abdichtung durch einen nach außen vorkragenden Flanschfortsatz despaper or fabric filter body on its four narrow sides at the height of one of the flat sides and consists of a highly elastic plastic and wherein the air filter insert is sealed at the edge by an outwardly projecting flange extension of the

Tragrahmens in ein Luftfiltergehäuse einsetzbar ist.Support frame can be inserted into an air filter housing.

Luftfiltereinsätze der eingangs genannten Art sind allgemein bekannt und verbreitet und werden z. B. in Kraftfahrzeugen verwendat, um dia vom Motor angesaugte Ver-Air filter inserts of the type mentioned above are well known and widespread and are used, for example, in motor vehicles to filter the air sucked in by the engine. brennungsluft oder die dem Kraftfahrzeug-Innenraum zv.geftthrte Frischluft zu reinigen. Der Luftfiltereinsatz wird hierzu in ein geteiltes Luftfiltergehäuse eingesetzt, wobei der am Luftfiltereinsatz vorhandene Flanschtortsatz zugleich als Dichtung für die Teilungsihige des Luftf11-combustion air or the fresh air supplied to the vehicle interior. The air filter insert is inserted into a split air filter housing, whereby the flange set on the air filter insert also serves as a seal for the divisible part of the air filter. tergehäuses dienen kann. Da bei den bekannten Filterein sätzen der Flanschfortsatz, wie dies aus Gründen einer möglichst &ogr;Infachen Herstellbarkelt naheliegend 1st, in Höhe der dom Tragrahmen benachbarten Flachaelte des Filterkörpers liegt, ist es erforderlich, bei d*r Konstruk-Since the flange extension of the known filter inserts is located at the height of the flat sides of the filter body adjacent to the support frame, as is obvious for reasons of ease of manufacture, it is necessary to design tion ein*· kompletten Luftfilters dessen Gehäuaegeataltung nach dan Vorgaben das Filtereinsatzes festzulegen. Hieraus ergibt sich der Nachteil, daß für die Gestaltungtion of a*· complete air filter, the housing design must be determined according to the specifications of the filter insert. This results in the disadvantage that for the design

dee Luftflltergehäueee nur nooh wenig Freiheit besteht, wee zu konstruktiven oder räumliche Problemen z. B. bei der unterbringung eines Luftfilters in eines Xraftfshr-3Eeug-Motorr«ua führen kann. Hn weiterer Nachteil 1st, daß vorhandene, noch nicht mit einem LuftfiltereineatzThere is still little freedom in the air filter housing , which can lead to structural or spatial problems, e.g. when accommodating an air filter in a X-Ray engine compartment. A further disadvantage is that existing, not yet equipped with an air filter insert

ausgestattete Luftführungs- oder Luftsammelgehäuse nicht ohne weiteres mit einem herkömmlichen Luftfiltereineatz versehbar sind, da zuvor Xnderungs- und Anpassungsarbelten an den vorhandenen Gehäusen erforderlich eind. 10equipped air duct or air collection housings cannot easily be fitted with a conventional air filter insert, as modifications and adjustments to the existing housings are required beforehand. 10

Be stellt eich daher die Aufgabe, einen Luftfiltereineatz der eingange genannten Art zu schaffen, der eine größere Freiheit bei der Gestaltung des zugehörigen Luftfiltergehauses geetattet und der an vorhandene Qehäueegegebenhel-•15 ten anpaßbar 1st.The task is therefore to create an air filter insert of the type mentioned above which allows greater freedom in the design of the associated air filter housing and which can be adapted to existing housings .

Die Lösung dieser Aufgabe gelingt neuerungegemaß durch einen Luftfiltereinsatz der eingangs genannten Art, welcher dadurch gekennzeichnet 1st, daß der Flanschfortsatz in einer Ebene angeordnet 1st, die gegenüber der Ebene der dem Tragrahmen benachbarten Flachseite des Filterkörpers in Richtung zu der anderen Flachseite des Filterkörpers höhenversetzt ist.This problem is solved in a new way by an air filter insert of the type mentioned at the beginning, which is characterized in that the flange extension is arranged in a plane which is offset in height from the plane of the flat side of the filter body adjacent to the support frame in the direction of the other flat side of the filter body.

Bei dem neuen Luftfiltereinsatz besteht die vorteilhafte Möglichkeit, die Lage des Flanschfortsatzes in gewissen Grenzen unabhängig von der Lage der Ebene der dem Tragrahmen benachbarten Flachseite des Filterkörpers zu wählen. Der neue Luftfiltereineatz ist daher an vorhandene Gehäuse anpassungsfähig bzw. bietet einen erweiterten Gestaltungespielraum bei der Konstruktion des zugehörigen Luftfiltergehäuses und ermöglicht so z. B. eine Vergrößerung der aktiven Filterfläche bei gleichbleibender äußerer Baugröße des Gehäuses. The new air filter insert offers the advantageous possibility of choosing the position of the flange extension within certain limits independently of the position of the plane of the flat side of the filter body adjacent to the support frame. The new air filter insert can therefore be adapted to existing housings and offers greater design freedom when constructing the associated air filter housing, thus enabling, for example, an increase in the active filter surface while maintaining the same external size of the housing.

In weiterer Ausgestaltung der Neuerung 1st vorgesehen, daß dsr Flanschfortsats in einer Ebene angeordnet ist.In a further embodiment of the innovation , it is provided that the flange extension is arranged in one plane.

dl« gegenüber der Ebene der dem Tragrahmen benachbarten Flacheelt· dee Fllterkörpere geneigt let. Hierdurch wird der Gestaltungeapielraum für Luftfiltereineatz und -gehäuse welter vergrößert und die Anpaeeungefählgkeit dee Luftfllterelneatzes wird erweitert. dl« the filter bodies are inclined relative to the plane of the flat surfaces adjacent to the support frame. This further increases the design space for the air filter insert and housing and increases the adaptability of the air filter insert .

Weiterhin sieht die Neuerung vor, daß die Ebenen der beiden Flachselten des Filterkörpers gegeneinander geneigt sind. Diese Auegestaltungevariante trägt lnsbeson-Furthermore, the innovation provides that the planes of the two flat sides of the filter body are inclined towards each other. This design variant contributes in particular

in dsrs zu einer verbesserten Ausnutzung von vorgegebenen räumlichen Verhältnissen für die Unterbringung eines Luftfilters bei, da hler nicht mehr, wie bisher üblich, eine reine Quaderform, sondern eine keilförmige Gestalt des Filterkörpers vorgesehen 1st.This contributes to an improved utilization of the given spatial conditions for accommodating an air filter, since the filter body no longer has a pure cuboid shape, as was previously the case, but rather a wedge-shaped shape.

Schließlich 1st bei dem Luftfiltereineatz noch wenigstens eine in die Oberseite und/oder Unterseite des Flanschfortsatzes eingelassene umlaufende Nut vorgesehen. Hierdurch wird im Zusammenwirken mit entsprechenden Stegen oder Vorsprüngen am Luftflitergehäuse ein sicherer Sitz des Luftfiltereinsatzes im Gehäuse und eine gute Abdichtung der Gehäuseteile gegenüber der Außenluft sowie der Zuluftseite gegenüber der Reinluftseite des Luftfilters erreicht.Finally, the air filter insert is provided with at least one circumferential groove set into the top and/or bottom of the flange extension. This, in conjunction with corresponding webs or projections on the air filter housing, ensures that the air filter insert is securely seated in the housing and that the housing parts are well sealed against the outside air and the supply air side against the clean air side of the air filter.

Im folgenden werden Ausführungsbeispiele der Neuerung anhand einer Zeichnung erläutert. Die Figuren der Zeichnung zeigen:In the following, examples of the innovation are explained using a drawing. The figures in the drawing show:

Die vier Schmalselten 33, 34, 35 und 36Filter paper or fabric and has a flat, cuboid shape. In the illustration according to Figure 1, the viewer's gaze falls on the upper flat side 31 of the filter body 3. The four narrow sides 33, 34, 35 and 36

•15 des Filterkörpers 3 stehen in Kontakt mit dem Innenumfang des Tragrahmens 2. An seinem Außenumfang besitzt der Tragrahmen 2 einen einstückig angeformten Flanschfortsatz 20, der sich frei vorkragend nach außen erstreckt. In die in Figur 1 sichtbare Oberseite des Flanschforteatzes 20•15 of the filter body 3 are in contact with the inner circumference of the support frame 2. On its outer circumference, the support frame 2 has an integrally formed flange extension 20, which extends freely outward. In the top of the flange extension 20 visible in Figure 1 ist schließlich noch eine um den Filterkörpsr 3 umlaufende Nut 21 eingelassen.Finally, a groove 21 is provided around the filter body 3.

Wie aus den beiden Hälften der Figur 1 ersichtlich ir-t, besteht bei der Konturierung des Flanschfortsatzes 20 eine weiteetgehende Gestaltungsfreiheit, um diesen anAs can be seen from the two halves of Figure 1, there is considerable freedom of design in the contouring of the flange extension 20 in order to adapt it to

vorgegebene Formen eines Luftfiltergehäuses anzupassen.to adapt to the given shapes of an air filter housing.

Figur 2 zeigt den Luftfiltereinsatz 1 aus Figur 1 in Stlrnaneicht auf die Schmalseite 36 des Filterkörpers 3.Figure 2 shows the air filter insert 1 from Figure 1 in direct view onto the narrow side 36 of the filter body 3.

Wie aus dieser Darstellung besonders deutlich wird, ist, wie üblich, der Tragrahmen 2 la Bereich der unteren Flachselte 32 des Filterkörpers 3 alt diesem verbunden. Neuerungswesentlich ist jedoch, im unterschied zu herkömmlichen Luftfiltereinsätzen, der Flanschfortsatz 20As is particularly clear from this illustration, the support frame 2 is, as usual, connected to the lower flat part 32 of the filter body 3. However, the key innovation, in contrast to conventional air filter inserts, is the flange extension 20 nicht in Höhe der Flachselte 32 des Filterkörpers 3,not at the level of the flat edge 32 of the filter body 3,

sondern in einer gegenüber dieser in Richtung zur oberen Flachseite 31 des Filt.erkörpers 3 höhenversetzten Ebenebut in a plane offset in height relative to this in the direction of the upper flat side 31 of the filter body 3

angeordnet. Jo nach gewunechter Lage de* Fllterkörpers 3 In eine» Luftfiltergehäuse kann der ria&echforteatz 20 mehr oder weniger weit von der unteren Flachseil· 32 bzw. oberen Flachaelte 31 dee Fllterkörpers 3 angeordnet sein. Depending on the desired position of the filter body 3, the air flow control 20 in an air filter housing can be arranged more or less far from the lower flat edge 32 or upper flat edge 31 of the filter body 3.

Weiterhin zeigt die Figur 2 In Ihren beiden Darstellungshälften, daß auch der untere Teil des Tragrahmens 2 sowie der Übergangsbereich von diesem zum Flanschforteatz 20 zur Anpassung an vorgegebene Gehäuseformen unterschiedlich konturlert werden können. Furthermore, Figure 2 shows in its two halves that the lower part of the support frame 2 as well as the transition area from this to the flange extension 20 can be contoured differently in order to adapt to given housing shapes.

Die Schnittdarstellung des Luftfllterelnaatzes 1 gemäß Figur 3 zeigt Insbesondere die Verbindung zwischen dem Tragrahmen 2 und dem Filterkörper 3. Wie Im Obergangsbereich zv?lachen den Schmalseiten 33 bzw. 35 und der unteren Flachseite 32 durch strichpunktierte Linien angedeutet ist, 1st das Material des Tragrahmens 2 bei dessen Angießen an den Filterkörper 3 teilweise in dessen Faltenzwischenräume geströmt und dort erstarrt.The sectional view of the air filter assembly 1 according to Figure 3 shows in particular the connection between the support frame 2 and the filter body 3. As is indicated by dash-dotted lines in the transition area between the narrow sides 33 and 35 and the lower flat side 32, the material of the support frame 2 partially flowed into the fold spaces when it was cast onto the filter body 3 and solidified there.

Im oberen Teil der Figur 3 ist im Bereich der oberen Flachseite 31 des Fllterkörpers 3 das ^ick-zack-förmlg gefaltete Filterpapier geschnitten.In the upper part of Figure 3, the zigzag-folded filter paper is cut in the area of the upper flat side 31 of the filter body 3.

Vom Tragrahmen 2 kragt wieder der Flanschfortsatz 20 nach außen hin vor, wobei die beiden Hälften der Figur 3 widder zwei unterschiedliche Konturierungen des Tragrahmens 2 sowie des Flanschfortsatzes 20 und der darin eingelassenen Nut 21 zeigen.The flange extension 20 again projects outwards from the support frame 2, with the two halves of Figure 3 again showing two different contours of the support frame 2 as well as the flange extension 20 and the groove 21 embedded therein.

Figur 4 schließlich zeigt den Luftfiltereinsatz 1 in einer geänderten Ausführungsform, wobei die Darstellungsweise derjenigen der Figur 2 entspricht, d. h. es handelt sich um eine Stirnaneieht. Im Unterschied zu dem zuvor beschriebenen Ausführungsbeispiel ist bei €..sv?. T ftfiltereinsatz 1 gemäß Figur 4 der vorkragende Flanschfortsatz 20 am Tragrahmen 2 nicht parallel zu den Flachseiten 31 und 32 des Filterkörpers 3 angeordnet, sondern Finally, Figure 4 shows the air filter insert 1 in a modified embodiment, the representation corresponding to that of Figure 2, ie it is a front view. In contrast to the previously described embodiment, in the air filter insert 1 according to Figure 4 the projecting flange extension 20 on the support frame 2 is not arranged parallel to the flat sides 31 and 32 of the filter body 3, but

gegen letzter« geneigt. Wie aus Figur 4 ersichtlich 1st, kann die Helgung In einem gewissen Umfang variiert werden, sodaß hiermit eine weitere Anpassungsmöglichkelt fur den Luftfiltereinsatz 1 an vorgegebene Gehauseverhaltnisse geschaffen 1st.inclined towards the last one. As can be seen from Figure 4, the angle can be varied to a certain extent, so that a further adaptation option for the air filter insert 1 to given housing conditions is created.
