Description

Die Erfindung betrifft ein Lüftungsgitter mit einem Gehäuse, welches zum einen eine Öffnung ausbildet, in die Lamellen eingesetzt sind, und zum anderen eine mit einem Schlitzschieber belegte Rückwand mit Schlitzen besitzt.The invention relates to a ventilation grille with a housing, which on the one hand forms an opening into which slats are inserted, and on the other hand has a rear wall with slots which is occupied by a slider.

Derartige Lüftungsgitter sind in vielfältiger Form und Ausführung bekannt. Sie dienen für Zu- und Abluft bei­spielsweise in Kanaleinbauten und weisen frontseitig senkrechte oder waagerechte Tropfenlamellen auf. Sie können aus Metall oder Kunststoff sein und vielfältigen Anwendungszwecken dienen.Such ventilation grilles are known in many forms and designs. They are used for supply and exhaust air, for example in duct installations, and have vertical or horizontal drop slats on the front. They can be made of metal or plastic and serve a variety of applications.

Bei den bisherigen Lüftungsgittern befinden sich die Lamellen in einem eigenen Gehäuserahmen, von welchem entsprechende Randstreifen zur Festlegung dieses Gehäuserahmens abkragen. Dem Gehäuserahmen ist dann ein zweiter Rahmen aufgesetzt, welcher die Anordnung mit dem Schlitzschieber trägt. In der Regel sind die meisten Teile dieses bekannten Lüftungsgitters durch Schweißen verbunden, was erhebliche Probleme bei der Verarbeitung von veredelten oder lackierten Blechen aufwirft.With the previous ventilation grilles, the louvres are located in their own housing frame, from which corresponding edge strips protrude to fix this housing frame. The housing frame is then placed on a second frame, which carries the arrangement with the slider. As a rule, most parts of this known ventilation grille are connected by welding, which poses considerable problems when processing refined or painted metal sheets.

Ferner gibt es in diesen Lüftungsgittern Übergänge von einem Rahmenteil zum anderen, welche beispielsweise Luftstrahlen ablenken und zu Wirbeln innerhalb der Lüftungsgitter führen. Des weiteren bilden sich an solchen Absätzen erhebliche Staubablagerungen, welche aus hygienischen Gründen nicht wünschenswert sind.Furthermore, there are transitions from one frame part to the other in these ventilation grilles, which, for example, deflect air jets and lead to eddies within the ventilation grilles. Furthermore, considerable dust deposits form on such heels, which are not desirable for hygienic reasons.

Die Erfinder haben sich zum Ziel gesetzt, ein Lüftungs­gitter der oben genannten Art zu entwickeln, bei welchem diese Nachteile vermieden werden, bei dem insbesondere die Herstellung erleichtert und aus diesem Grund kostengünstiger ist. Ferner soll der Material­einsatz so gering wie möglich gehalten werden und ein Reinigen des Lüftungsgitters erleichtert sein.The inventors have set themselves the goal of developing a ventilation grille of the type mentioned above, in which these disadvantages are avoided, in which, in particular, the manufacture is simplified and is therefore more cost-effective. Furthermore, the use of materials should be kept as low as possible and cleaning of the ventilation grille should be made easier.

Zur Lösung dieser Aufgabe führt, daß das Gehäuse ein­stückig ausgebildet ist.To achieve this object, the housing is formed in one piece.

Durch diese einstückige Ausbildung des Gehäuses werden Kanten und Absätze innerhalb des Gehäuses vermieden, so daß zum einen die Luftführung verbessert ist. Weder an einer Kante noch an einem Absatz kann sich in dem erfindungsgemäßen Lüftungsgitter der Luftstrahl stoßen und hierdurch abgelenkt werden. Dadurch bleibt der gesamte Innenraum des Lüftungsgitters wirbelfrei und kann für die Zuluftführung verwendet werden.This one-piece design of the housing avoids edges and shoulders within the housing, so that on the one hand the air flow is improved. The air jet in the ventilation grille according to the invention can neither bump on an edge nor on a shoulder and can thereby be deflected. This means that the entire interior of the ventilation grille remains vortex-free and can be used for the supply air duct.

Zum anderen ist das ganze Gitter wesentlich leichter zu warten und zu reinigen, weil keine störenden, umlaufenden Absätze vorhanden sind, über die das Gitter zusammengebaut ist. Staubablagerungen, Bakterien od. dgl. Unrat kann sich in dem Lüftungsgitter nicht mehr einnisten.On the other hand, the entire grille is much easier to maintain and clean because there are no annoying, circumferential paragraphs over which the grille is assembled. Dust deposits, bacteria or the like. Debris can no longer nest in the ventilation grille.

Bevorzugt sind aus einem einzigen Materialstreifen von einer Rückwand Seitenwände abgekantet, welche eine eigentliche Gehäusebox ausbilden. In dieser Gehäusebox sitzt dann der Schlitzschieber und die Lamellen.Side walls, which form an actual housing box, are preferably folded from a single material strip from a rear wall. The slider and the slats then sit in this housing box.

Ferner werden von den Seitenwänden Randstreifen abgebogen, so daß das gesamte Lüftungsgitter von vorne gesehen einen ästhetisch ansprechenden, umlaufenden, gleichmäßigen Rahmen besitzt.Furthermore, edge strips are bent from the side walls, so that the entire ventilation grille has an aesthetically pleasing, all-round, uniform frame when viewed from the front.

Bevorzugt überlappen sich die Randstreifen in den Eck­bereichen und sind hier miteinander und ggfs. auch mit einem entsprechenden Rohr oder Blechkanal der Klima­anlage verbunden. Die Verbindung geschieht beispielsweise über eine Lochniete, so daß ein Schweißen für dieses Lüftungsgitter vollkommen entfällt.The edge strips preferably overlap in the corner areas and are here connected to one another and possibly also to a corresponding pipe or sheet metal duct of the air conditioning system. The connection takes place, for example, via a perforated rivet, so that welding for this ventilation grille is completely eliminated.

Damit ist auch die Möglichkeit gegeben, das Lüftungs­gitter aus Stahlblech, Aluminium, lackiertem Blech, verzinktem Blech, Chrom-Nickel-Stahl oder auch aus Kunststoff zu fertigen. Abgesehen davon sind Schweiß­arbeiten immer umweltbelastend.This also makes it possible to manufacture the ventilation grille from sheet steel, aluminum, painted sheet metal, galvanized sheet metal, chrome-nickel steel or even from plastic. Apart from that, welding work is always harmful to the environment.

Die Lamellen werden einfach über ihre Achsen in ent­sprechende Bohrungen des Gehäuses eingesetzt, wobei jede einzelne Lamelle für sich um ihre Achse gedreht und damit verstellt werden kann. Auch dies ist ein sehr einfacher und leichter Arbeitsschritt.The slats are simply inserted into the corresponding holes in the housing via their axes, whereby each individual slat can be rotated around its axis and thus adjusted. This is also a very simple and easy step.

Der Schlitzschieber besitzt Schlitze, welche bevorzugt durch Stanzungen ausgeformt sind. Dabei bleibt das ausgestanzte Material über eine Kante mit dem Schlitz­schieber verbunden und ist lediglich aus dem Schlitz herausgebogen. Auch hierdurch wird die Luftführung innerhalb des Lüftungsgitters verbessert, da durch die herausgebogenen Flügel die einzelnen Luftströme der nebeneinander liegenden Schlitze voneinander abgeschirmt sind.The slot slide has slots, which are preferably formed by punching. The punched-out material remains connected to the slot slider via an edge and is only bent out of the slot. This also improves the air flow within the ventilation grille, since the individual air streams of the adjacent slots are shielded from one another by the bent-out blades.

Der Schlitzschieber selbst besitzt oben und unten je einen Führungsstreifen, welcher in Gebrauchslage von einem Klammerstreifen od. dgl. übergriffen ist und so in dem Gehäuse festliegt. Der Klammerstreifen ist dabei so ausgelegt, daß der Schlitzschieber in einem gewissen Bereich verschoben werden kann und hierdurch die Öffnungsweite der Schlitze verändert wird.The slot slide itself has a guide strip at the top and bottom, which is overlapped by a clip strip or the like in the position of use and is thus fixed in the housing. The clip strip is designed so that the slider can be moved within a certain range and this changes the opening width of the slots.

Dieses erfindungsgemäße Lüftungsgitter besteht aus nur wenigen Einzelteilen, weshalb der Materialeinsatz so gering wie möglich ist.This ventilation grille according to the invention consists of only a few individual parts, which is why the use of materials is as low as possible.

Aber auch das erfindungsgemäße Herstellungsverfahren zeigt die geringe Zahl von Arbeitsschritten, welche zu erheblichen Kosteneinsparungen führen. Erfindungsgemäß werden aus einem Materialstreifen die Schlitze für die Rückwand ausgestanzt, danach die Seitenwände abge­kantet, so daß eine Gehäusebox entsteht und danach die Randstreifen nach außen abgebogen, die dann in den überlappenden Bereichen miteinander verbunden werden. Hierdurch entsteht das Grundgehäuse.However, the manufacturing method according to the invention also shows the small number of work steps which lead to considerable cost savings. According to the invention, the slits for the rear wall are punched out of a material strip, then the side walls are bent, so that a housing box is created and then the edge strips are bent outwards, which are then connected to one another in the overlapping areas. This creates the basic housing.

Des weiteren werden aus einem Materialstreifen die Schlitze des Schlitzschiebers unter Ausbildung von Flügeln ausgestanzt und von zwei Seiten Führungs­streifen abgekantet. Dieser Schlitzschieber wird dann in das Gehäuse eingesetzt und über Klammerstreifen festgelegt. Danach müssen lediglich die Lamellen mit ihren Achsen in die entsprechenden Bohrungen des Gehäuses bzw. in die Öffnungen eingesetzt werden.In addition, the slots of the slot slide are punched out from a material strip to form wings and guide strips are bent from two sides. This slider is then inserted into the housing and fixed using clamp strips. Then all you have to do is insert the slats with their axes into the corresponding holes in the housing or into the openings.

Weitere Vorteile, Merkmale und Einzelheiten der Er­findung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung; diese zeigt in

  • Fig. 1 eine Frontansicht eines erfindungsgemäßen Lüftungsgitters;
  • Fig. 2 einen Querschnitt durch das Lüftungsgitter gemäß Figur 1 entlang Linie II-II;
  • Fig. 3 einen teilweise dargestellten Längsschnitt durch das Lüftungsgitter gemäß Figur 1 entlang Linie III-III.
Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing; this shows in
  • 1 is a front view of a ventilation grille according to the invention;
  • 2 shows a cross section through the ventilation grille according to FIG. 1 along line II-II;
  • Fig. 3 is a partially shown longitudinal section through the ventilation grille according to Figure 1 along line III-III.

Ein erfindungsgemäßes Lüftungsgitter R besteht gemäß Figur 1 aus einem Gehäuse 1, welches eine frontwärtige Öffnung 2 ausbildet. Dieses Gehäuse 1 ist aus einem Materialstreifen hergestellt. Es besitzt eine in Figur 3 deutlich erkennbare Rückwand 3, in welche Schlitze 4 eingestanzt sind.According to FIG. 1, a ventilation grille R according to the invention consists of a housing 1 which forms a front opening 2. This housing 1 is made from a strip of material. It has a rear wall 3 which can be clearly seen in FIG. 3 and into which slots 4 are stamped.

Von der Rückwand 3 sind Seitenwände 5 und 6 abgekantet, welche eine eigentliche Gehäusebox ausbilden.Side walls 5 and 6 are bent from the rear wall 3 and form an actual housing box.

Von jeder Seitenwand 5 kragt ein Randstreifen 7 bzw. 8 ab, welche sich in den Eckpunkten überlappen und dort mittels Nieten 9 miteinander verbunden sind. Diese Lochniete 9 in den Nieteckpunkten dient gleichfalls zur Befestigung des Lüftungsgitters R beispielsweise an einem Blechkanal einer Klimaanlage od. dgl..An edge strip 7 or 8 protrudes from each side wall 5, which overlap in the corner points and is connected there by rivets 9. This rivet 9 in the rivet corner points also serves to fasten the ventilation grille R, for example to a sheet metal duct of an air conditioning system or the like.

Durch die Öffnung 2 hindurch ist auf die Rückwand 3 ein Schlitzschieber 10 aufgelegt, bei welchem ebenfalls durch Ausstanzungen Schlitze 11 ausgebildet sind, welche im wesentlichen mit den Schlitzen 4 der Rückwand 3 übereinstimmen. Die Stanzung der Schlitze 11 erfolgt entlang von drei umlaufenden Seiten des Schlitzes, so daß ein ausgestanzter Flügel 12 abgebogen werden kann. Hierdurch wird u. a. eine Wirbelbildung innerhalb des Gehäuses 1 bzw. der eigentlichen Gehäusebox vermieden.A slot slider 10 is placed through the opening 2 on the rear wall 3, in which slots 11 are also formed by punching, which essentially correspond to the slots 4 of the rear wall 3. The slots 11 are punched along three circumferential sides of the slot, so that a punched-out wing 12 can be bent. This will u. a. a vortex formation within the housing 1 or the actual housing box avoided.

Nach oben und nach unten hin sind von dem Schlitz­schieber 10 noch Führungsstreifen 13 und 14 abgekantet. Diese Führungsstreifen 13 bzw. 14 werden teilweise von Klammerstreifen 15 (siehe Figur 2) übergriffen, welche einen Gehäuseboden 16 durchsetzen, wie dies in Figur 3 gestrichelt dargestellt ist. Die Klammerstreifen 15 sind so angeordnet, daß ein Verschieben des Schlitz­schiebers 10 entlang der Rückwand 3 freigegeben ist, so daß die Schlitze 4 ganz oder teilweise geöffnet bzw. geschlossen werden können.Guide strips 13 and 14 are also bent upward and downward from the slit slide 10. These guide strips 13 and 14 are partially overlapped by clamp strips 15 (see FIG. 2) which penetrate a housing base 16, as shown in broken lines in FIG. The clamp strips 15 are arranged in such a way that a displacement of the slot slide 10 along the rear wall 3 is released, so that the slots 4 can be opened or closed in whole or in part.

In die Öffnung 2 des Gehäuses 1 sind senkrechte Lamellen 17 eingesetzt und um eine Achse 18 drehbar. Selbstverständlich können anstelle von senkrechten Lamellen auch waagerechte Lamellen vorgesehen sein. Bevorzugt ist jede Lamelle 17 für sich um ihre Achse 18 bewegbar.Vertical slats 17 are inserted into the opening 2 of the housing 1 and can be rotated about an axis 18. Of course, horizontal slats can also be provided instead of vertical slats. Each lamella 17 is preferably movable about its axis 18.
