Abstract

The filter cartridge is pushed into the shaft of a channel of a ventilation/air conditioning plant. The cartridge cover also covers the shaft, and is clamped in position by a clamp, which has locking bars projecting from cover and channel. The cover (9) forms part of the filter frame (5), which projects into the shaft (2). The shaft decreases in size constantly, and the filter (3) is similarly shaped. When the filter is completely inserted, its frame engages on a seal (6). The clamp (12) is put in place, causing a further insertion movement, to press the filter against the seal. USE/ADVANTAGE - No damage to seal during movement of filter in cartridge, no leakage air once cover is clamped down.

Description

Die Erfindung betrifft ein von einer Kassette aufgenommenes, in einen Schacht eines Kanales einer Lüftungs- oder Klimaanlage einschiebbares Filter, dessen den Schacht einschubseitig ver­ schließender Deckel durch mindestens eine deckel- oder kanal­ seitig verschiebbar gehaltene Klammer mit vom Deckel und vom Kanal abragenden Verriegelungsstegen verspannbar ist.The invention relates to a recorded in a cassette a duct of a ventilation or air conditioning system insertable filter, the ver the shaft on the insertion side closing lid by at least one lid or channel laterally displaceable clamp with the lid and the Channel protruding locking bars can be clamped.

Ein derartig angeordnetes und auf einfache Weise festlegba­ res Filter ist durch die DE 40 21 460 A1 bekannt. Filter und Schacht sind parallel zueinander ausgerichtet, so daß sich zum Erhalt der erforderlichen Dichtwirkung hohe Ein- und Aus­ schubkräfte ergeben, die die notwendigerweise zwischengeschal­ tete Dichtung bei der Schiebebewegung beschädigen können. Au­ ßerdem stützt sich der Deckel an der Schachtwand ab, so daß nicht gewährleistet ist, daß bodenseitig des Filters keine Leckluft übertritt.Such an arranged and easy to fix res filter is known from DE 40 21 460 A1. Filters and Manhole are aligned parallel to each other so that high on and off to maintain the required sealing effect result in thrust forces that necessarily form the interposed can damage the seal during the sliding movement. Au In addition, the lid is supported on the shaft wall, so that it is not guaranteed that none at the bottom of the filter Leakage air overflows.

Es ist Aufgabe der Erfindung, Filter und Filteraufnahme so zu gestalten, daß bei geringen Ein- und Ausschubkräften keine Ge­ fahr der Beschädigung der Dichtung gegeben ist und außerdem sichergestellt ist, daß bei verspanntem Deckel auch bodensei­ tig des Filters keine Leckluft passieren kann.It is an object of the invention to filter and filter holder design that with low insertion and extension forces no Ge Risk of damage to the seal and also it is ensured that when the lid is tightened also bottom leakage air cannot pass through the filter.

Diese Aufgabe wird bei einem von einer Kassette aufgenommenen Filter gemäß dem Oberbegriff des Patentanspruches 1 durch des­ sen kennzeichnende Merkmale gelöst. This task is performed on a cassette Filter according to the preamble of claim 1 by the characteristic features solved.  

Ist ein Filteraustausch in kürzeren Abständen notwendig, so ist es zur Gewährleistung der geforderten Dichtigkeit vorteilhaft, wenn die Dichtung am Rahmen des Filters befestigt ist. Wenn ein Filterwechsel nur in großen Zeitabständen notwendig ist, kann die Dichtung schachtseitig festgelegt sein.If a filter replacement at shorter intervals is necessary, then it is advantageous to ensure the required tightness, when the gasket is attached to the frame of the filter. When a Filter change is only necessary at large time intervals the seal must be fixed on the shaft side.

Bei einem den ganzen Kanalquerschnitt zur Filterbeaufschlagung nutzenden Ausführungsbeispiel läuft der Schacht an seiner der Einschubseite des Filters entgegengesetzten Seite in einen aus der Wand des Kanals herausgeformten Topf aus, in den der Rahmen bodenseitig dichtend eintaucht.With a the entire channel cross section for filter application using the embodiment, the shaft runs on its Insertion side of the filter opposite side in one out molded out the wall of the channel into which the frame immersed sealingly on the bottom.

Bei einem anderen erfindungsgemäßen Ausführungsbeispiel stützt sich der Rahmen bodenseitig unter Zwischenschaltung eines Dich­ tungsabschnittes an der der Einschubseite des Filters gegenüber­ liegenden Seite des Kanales ab.In another embodiment of the invention supports the frame on the bottom side with the interposition of a you tion section opposite the insertion side of the filter lying side of the channel.

Anhand von zwei in der Zeichnung dargestellten Ausführungsbei­ spielen wird der Gegenstand der Erfindung nachfolgend näher beschrieben. Es zeigtBased on two examples shown in the drawing will play the subject of the invention in more detail below described. It shows

Fig. 1 ein von einem Kanal aufgenommenes Filter, dessen Rahmen bodenseitig in einen aus der zugeordneten Kanalwand herausgeformten Topf eintaucht und Fig. 1 is a filter received by a channel, the frame immersed in the bottom of a molded out of the associated channel wall pot and

Fig. 2 ein kanalseitig aufgenommenes Filter, dessen Rah­ men sich bodenseitig unter Zwischenschaltung ei­ nes Dichtungsabschnittes abstützt. Fig. 2 is a channel-side filter, the frame men is supported on the bottom side with the interposition of egg nes sealing section.

Ein Frischluft zu einer nicht dargestellten Lüftungs- oder Kli­ maanlage führender Kanal 1 weist einen Schacht 2 auf, der ein Filter 3 einschiebbar aufnimmt. Das als Filtermaterial zick­ zackförmig gefaltetes Filterpapier 4 beherbergende Filter 3 ist von einem Rahmen 5 umgeben, dem lufteinlaß- und luftauslaßsei­ tig eine Dichtung 6 angelagert ist. Ausgehend von der Einschub­ seite des Filters 3 verjüngt sich der Schacht 2 stetig, so daß beim Einschieben des sich im selben Maße verjüngenden Filters 3 sich dessen Rahmen 5 erst bei seinem Eintauchen in einen gegen­ über der Filtereinschuböffnung aus der Wand 7 des Kanales 1 herausgeformten Topf 8 über die Dichtungen 6 am Schacht 2 ab­ stützt, wobei erst zu diesem Zeitpunkt die geringe Einschub­ kraft merkbar ansteigt.A fresh air leading to a ventilation or air conditioning system not shown duct 1 has a shaft 2 , which receives a filter 3 insertable. The as filter material in a zig-zag pleated filter paper 4 harboring filter 3 is surrounded by a frame 5 which is the air inlet and luftauslaßsei tig attached a seal. 6 Starting from the insertion side of the filter 3 , the shaft 2 tapers steadily, so that when the filter 3 , which is tapering to the same extent, is inserted, its frame 5 is only formed when it is immersed in a pot that is formed over the filter insertion opening from the wall 7 of the channel 1 8 based on the seals 6 on the shaft 2 , only at this point the small insertion force increases noticeably.

Die kanalseitige Filtereinschuböffnung wird bei eingesetztem Filter 3 durch einen Deckel 9 verschlossen, der einen Bestand­ teil des Rahmens 5 bildet und in den Schacht 2 eintaucht. Vom Deckel 9 und vom Kanal 1 ragen Verriegelungsstege 10 und 11 ab, die beim Verschieben von deckelseitig verschiebbar aufgenomme­ nen Klammern 12, von denen nur eine ersichtlich ist, gegenein­ ander verspannt werden, wie dies in der DE 40 21 460 A1 näher beschrieben ist. Bei diesem Verspannungsvorgang, bei dem der äußere Abschnitt der Klammer 12 auf nicht dargestellte Rampen der Verriegelungsstege 11 aufläuft, erfolgt eine weitere ge­ ringe Einschubbewegung des Filters 3, so daß dessen Rahmen 5 mit seinen Dichtungen 6 sich an die Wände des Schachtes 2 an­ preßt.The channel-side filter insertion opening is closed when the filter 3 is inserted by a cover 9 , which forms part of the frame 5 and dips into the shaft 2 . From the cover 9 and from the channel 1 locking webs 10 and 11 protrude, which are displaceably received when moving cover-side slidably received clamps 12 , of which only one can be seen, against one another, as is described in more detail in DE 40 21 460 A1. In this bracing process, in which the outer portion of the bracket 12 runs on ramps, not shown, of the locking webs 11 , a further ge insertion movement of the filter 3 takes place , so that its frame 5 with its seals 6 presses against the walls of the shaft 2 .

Beim Ausführungsbeispiel nach Fig. 2 weist die der Filterein­ schuböffnung gegenüberliegende Wand des Kanales 1 eine glatte Anlagefläche für den bodenseitigen Abschnitt des Rahmens 5 auf, der in diesem Anlegebereich mit einem Dichtungsabschnitt 13 versehen ist. Ordnet man die Dichtung 6 und den Dichtungsab­ schnitt 13 dem Rahmen 5 zu, so ist die Gewähr gegeben, daß beim Einsetzen eines neuen Filters 3 Dichtprobleme nicht auftreten können. Diese Dichtungszuordnung wird gewählt, wenn es sich bei dem Filter 3 um ein Stäube zurückhaltendes Filter 3 handelt, das öfters gewechselt werden muß. Handelt es sich dagegen um ein schädliche gasförmige Bestandteile zurückhaltendes Filter 3 mit einer Aktivkohlefüllung, das nur sehr selten getauscht wer­ den muß, so ergeben sich Kostenvorteile, ohne daß es zu Dicht­ problemen kommt, wenn die Dichtung 6 und der Dichtungsabschnitt 13 am Schacht 2 festgelegt werden.In the exemplary embodiment according to FIG. 2, the wall of the channel 1 opposite the filter insertion opening has a smooth contact surface for the bottom section of the frame 5 , which is provided with a sealing section 13 in this contact area. If you assign the seal 6 and the Dichtungsab section 13 to the frame 5 , there is a guarantee that 3 sealing problems can not occur when inserting a new filter. This seal assignment is chosen if the filter 3 is a dust-retaining filter 3 , which has to be changed frequently. If, on the other hand, it is a harmful gaseous constituent filter 3 with an activated carbon filling, which has to be exchanged only very rarely, there are cost advantages without sealing problems if the seal 6 and the sealing section 13 are fixed on the shaft 2 will.
