Abstract

The air outlet (1) has a frame (3), which encloses an opening, and has at least two elongated wedge-shaped slats (4). Each slat has two end surfaces, and two longitudinal sides which span between the surfaces, and which diverge from a common vertex towards a base side. The base side has a concave longitudinal groove. Each slat is mounted on the frame by equipment (5) which allows it to pivot. The frame has equipment to pivot all the slats. All the slats may be arranged parallel to one another, or may be arranged in neighbouring groups at angles to one another. The hinge axis of the each slat may also be near the vertex or the base side.

Description

In der EP-B-0 267 486 ist ein verstellbarer Luftauslaß mit Injektorwirkung beschrieben. Der Luftauslaß ist dazu vorgesehen, an Auslaßöffnungen von Luft- oder Klimaschächten installiert zu werden und weist einen eine rechteckige Öffnung begrenzenden Rahmen auf. In dem Rahmen sind parallel zueinander eine Vielzahl streifenförmiger Lamellen schwenkbar gelagert. Jede Lamelle besteht aus einem dünnen Material, wobei die Rückseite zu der Vorderseite der Lamelle parallel verläuft. Jeweils zwei benachbarte Lamellen bilden ein Paar und sind auf einer gemeinsamen Scharnierachse, die sich über die durch den Rahmen definierte Öffnung erstreckt. Jedes so gebildete Paar von Lamellen ist von dem jeweils benachbarten Paar ein Stück weit beabstandet. Die benachbarten Lamellen zweier Paare von Lamellen begrenzen eine schlitzförmige Düse, durch die aus dem Kanal zugeführte Luft in den zu belüftenden Raum austritt. Wegen der höheren Luftgeschwindigkeit der aus der schlitzförmigen Düse austretenden Luft wird Raumluft angesaugt, die durch den Raum, der zwischen den Lamellen eines Paares begrenzt ist, zuströmt.In EP-B-0 267 486 there is an adjustable air outlet described with injector effect. The air outlet is provided at outlet openings of air or climate shafts to be installed and has a rectangular opening bounding frame. In the frame are a multiplicity of strip-shaped in parallel Slats pivoted. Each slat is made of a thin material, the Back runs parallel to the front of the slat. Two adjacent ones Slats form a pair and are on a common one Hinge axis that is defined by the frame Opening extends. Each pair of Slats are one piece from the adjacent pair widely spaced. The adjacent slats of two pairs of slats delimit a slit-shaped nozzle through which Air supplied from the duct into the room to be ventilated exit. Because of the higher airspeed The air emerging from the slit-shaped nozzle becomes room air sucked in by the space between the slats of a couple is limited.

Um eine einigermaßen ruhige Strömung der Injektor- oder Sekundärluft zu erreichen, sind die streifenförmigen Lamellen zylinderförmig konvex gekrümmt, wobei die Krümmungsachse auf der Seite der Lamelle liegt, auf der auch die zugehörige Lamelle des selben Paares angeordnet ist.For a reasonably calm flow of the injector or to reach secondary air are the stripe-shaped Lamellae curved in a convex shape, the axis of curvature is on the side of the slat, on which too the associated lamella of the same pair is arranged.

Um sowohl die Strömungsrichtung als auch die Luftmenge variieren zu können, sind zwei Verstellstangen vorgesehen. Die eine Verstellstange ist mit jeder zweiten Lamelle des Luftauslasses gelenkig verbunden, während die andere Stange an den dazwischenliegenden Lamellen angelenkt ist. Durch gemeinsame Betätigung beider Stangen wird die Luftausströmrichtung verändert, während eine gegensinnige Betätigung beider Hebel die Weite der Düsenschlitze verstellt.About both the direction of flow and the amount of air To be able to vary, two adjustment rods are provided. One adjustment rod is with every second slat of the air outlet articulated while the other Rod is articulated to the intermediate slats. By operating both rods together, the air outflow direction changed while an opposite Operation of both levers adjusts the width of the nozzle slots.

Wegen der Verwendung zweier Einstellstangen ist die Bedienung der Düse problematisch, denn, wenn die Weite der schlitzförmigen Düsen zu stark vergrößert wird, fällt die Injektorwirkung praktisch weg, weil der zwischen den schlitzförmigen Düsen gebildete Raum zu klein ist, als das genügend Raumluft angesaugt werden kann. Die Konsequenz ist ein schlechter Wirkungsgrad und ein unnötiger Energieverbrauch. Da von den Personen, die sich in einem durch einen solchen Luftauslaß belüfteten Raum befinden, keine hinreichende Einsicht in eine sinnvolle Einstellung des Luftauslasses erwartet werden kann, kann der Luftauslaß eigentlich nur durch die Installationsfirma fest eingestellt werden und eine Einstellung durch die Benutzer ist weitgehend ausgeschlossen. Gleichwohl kann es aber durchaus erforderlich sein, witterungsbedingt oder bedingt durch Änderungen der Ausstattung des Raums oder der Aufenthaltsplätze den Luftauslaß auch verstellbar haben zu wollen, ohne zur Neujustage die Installationsfirma bemühen zu müssen. Because of the use of two adjusting rods, the Operation of the nozzle is problematic because if the width of the slit-shaped nozzles is enlarged too much, the falls Injector effect practically gone because of the between the slot-shaped nozzles formed space is too small than that enough room air can be sucked in. The consequence is poor efficiency and unnecessary energy consumption. Because of the people who are in one there is no such ventilated room sufficient insight into a meaningful attitude of the Air outlet can be expected, the air outlet actually only permanently set by the installation company and is an attitude by the users largely excluded. Nevertheless, it can be necessary, weather-related or conditional by changing the equipment of the room or the places to stay also have the air outlet adjustable want without having to make an effort to readjust the installation company to have to.

Ausgehend hiervon ist es Aufgabe der Erfindung einen Luftauslaß zu schaffen, der ohne die Gefahr von Fehlbedienungen in der Strahlrichtung veränderbar ist.Based on this, it is an object of the invention To create air outlet without the risk of incorrect operation is changeable in the beam direction.

Diese Aufgabe wird erfindungsgemäß durch den Luftauslaß mit den Merkmalen des Anspruches 1 gelöst.This object is achieved by the air outlet solved with the features of claim 1.

Aufgrund der keilförmigen Lamellen ist der Raum, über den Raumluft von den Injektorstrahlen angesaugt wird, fest definiert, und zwar einfach aufgrund der Breite der keilförmigen Lamellen an ihrer Basisfläche. Die, verglichen mit dem Stand der Technik, glatte Seite liefert eine gute zuströmmöglichkeit der Raumluft, weil keine Kanten oder Erhebungen vorhanden sind, die zu einer vorzeitigen Verwirbelung der Luft und damit einer Verringerung des effektiven Zuströmquerschnitts führen. Besonders günstige Verhältnisse ergeben sich, wenn die Basisseite der keilförmigen Lamellen zylinderförmig konkav gekrümmt ist. Dann wird der zwischen den Injektorstrahlen bestehende Zuströmquerschnitt für die Raumluft entsprechend der Tiefe der zylinderförmig konkav gekrümmten Basisseite vergrößert.Because of the wedge-shaped slats, the space is over the room air is sucked in by the injector jets defined, simply because of the width of the wedge-shaped Slats on their base surface. The, compared with the prior art, smooth side provides a good Possibility of inflow of indoor air because no edges or Surveys exist that lead to premature turbulence the air and thus a reduction in the effective Lead inflow cross section. Particularly cheap Ratios arise when the base side of the wedge-shaped Slats are concavely curved in a cylindrical shape. Then becomes the inflow cross section existing between the injector jets for indoor air according to the depth of the enlarged concave curved base side.

Wenn der Luftauslaß gleichzeitig in mehrere unterschiedliche Raumrichtungen die Luft auswerfen soll, können die Lamellen lediglich gruppenweise zueinander parallel sein, das heißt, in ein und dem selben Rahmen befinden sich mehrere Lamellengruppen, die in unterschiedliche Richtung die Injektorluft leiten.If the air outlet into several different at the same time Spatial directions that air should eject the slats only parallel to each other in groups be, that is, in the same frame there are several slat groups in different Direct the injector air.

Eine ruhigere Strömung der Injektorluft und damit eine bessere Injektorwirkung wird erzielt, wenn die Längsseiten konvex gekrümmt sind, wobei die Krümmungsachsen in Längsrichtung der Lamelle liegen.A calmer flow of the injector air and thus a better injector effect is achieved if the long sides are convexly curved, the axes of curvature in Longitudinal direction of the slat.

Die Lagereinrichtung der Lamellen ist vorzugsweise ein Scharnier, durch das die Lamelle um eine Scharnierachse schwenkbar ist, die zu der Längsrichtung der Lamelle parallel liegt. The storage device of the slats is preferred a hinge through which the slat is about a hinge axis is pivotable to the longitudinal direction of the slat lies in parallel.

Wenn die Scharnierachse in der Nähe des Scheitels der Lamelle liegt, kann die Verstelleinrichtung weitgehend außerhalb und damit leichter zugänglich angeordnet sein. Gleichzeitig ragen hierdurch die keilförmigen Lamellen nur wenig in den Kanal, der sie mit Luft versorgt, hinein, ohne dort nennenswert die Strömung zu behindern. Es ist aber auch möglich, die Scharnierachse in die Nähe der Basisseite zu verlegen, was den Vorteil mit sich bringt, daß die Hebelmechanik zum Verstellen der Lamellen weitgehend im Innern des Luftauslasses verschwindet. Der Luftauslaß gestaltet sich dann nach außen sehr flach.If the hinge axis is near the apex of the Slat lies, the adjustment can largely be arranged outside and thus more easily accessible. At the same time, the wedge-shaped slats only protrude little into the channel that supplies them with air, without noticeably hindering the flow there. It is but also possible to close the hinge axis To lay the base side, which has the advantage that the lever mechanism for adjusting the slats largely disappears inside the air outlet. The air outlet is then very flat on the outside.

Die Lamellen bestehen vorzugsweise aus einem Leichtmetallstrangpreßprofil mit entsprechender Außenkontur, wobei im Inneren ein durchgehender Hohlraum zur Material- und Gewichtsersparnis enthalten ist. Dieser Hohlraum wird von entsprechenden Platten, die die Seitenflächen bilden, verschlossen.The slats preferably consist of a light metal extruded profile with appropriate outer contour, with a continuous cavity inside for material and weight saving is included. This cavity will of corresponding plates that form the side surfaces, locked.

Die Verstelleinrichtung umfaßt an den einzelnen Lamellen vorgesehene Anlenkungspunkte oder Anlenkungsstellen, deren Abstand von der Schwenkachse der Lamelle von der Lage der jeweiligen Lamelle in dem Rahmen abhängig ist. Hierdurch ändert sich bei einem Verschwenken der Lamellen deren Schwenkwinkel unterschiedlich. So kann beispielsweise auf diese Weise in einer Einstellung der Lamellen ein relativ geringer Öffnungswinkel des austretenden Gesamtluftstroms erzielt werden, während in einer anderen Einstellung, in der die Lamellen unterschiedlich stark verschwenkt sind, ein großer Öffnungswinkel erzielt werden kann.The adjustment device includes the individual Lamella provided articulation points or articulation points, their distance from the pivot axis of the slat depending on the position of the respective slat in the frame is. This changes when pivoting the Slats whose swivel angle is different. So can for example this way in a setting of Slats a relatively small opening angle of the emerging Total airflow can be achieved while in one different setting in which the slats are different are strongly pivoted, a large opening angle is achieved can be.

Universelle, an jeder Stelle innerhalb der Öffnung einbaubaren Lamellen werden erhalten, wenn jede Lamelle auf ihrer Stirnfläche sämtliche mögliche Anlenkungsstellen aufweist, die für den jeweiligen Luftauslaß in Frage kommen. Universal, anywhere in the opening built-in slats are obtained when each slat on its face all possible articulation points has that for the respective air outlet in question come.

Eine gleichsinnige Verstellung sämtlicher Lamellen mit von Lamelle zu Lamelle sich änderndem Verstellwinkel wird erreicht, wenn alle zueinander parallelen Lamellen an wenigstens einer gemeinsamen Verstellstange angelenkt sind. Es ist aber auch ohne weiteres möglich, Gruppen zu bilden, so daß beispielsweise bei einem in einer Wand eingebauten Luftauslaß in der unteren Hälfte angeordneten Lamellen stärker verstellt werden, als die Lamellen in der oberen Halbgruppe. Dies läßt sich einfach dadurch erreichen, daß bei den Lamellen der oberen Halbgruppe die Anlenkungsstellen den selben Abstand von der Schwenkachse haben und von der Schwenkachse weiter entfernt liegen, als die Anlenkungsstellen an den Lamellen der unteren Halbgruppe, wobei bei diesen auch wieder innerhalb der Gruppe der Abstand der Anlenkungsstellen von der Scharnier- oder Schwenkachse gleich ist. Beide Gruppen sind durch eine Stange verbunden, so daß eine gleichzeitige Verstellung, aber mit unterschiedlichen Winkeln erfolgt. Bei einem derartigen Luftauslaß sind die Injektorstrahlen innerhalb jeder Gruppe bei jeder Einstellung des Luftauslasses zueinander parallel, aber je nach Einstellung des Luftauslasses divergieren die Injektorstrahlen der beiden Gruppen mehr oder weniger.The same adjustment of all slats with an adjustment angle that changes from slat to slat is achieved when all parallel slats on articulated at least one common adjustment rod are. But it is also possible to add groups form, so that for example in a wall built-in air outlet arranged in the lower half Slats are adjusted more than the slats in the upper half group. This can be achieved simply by that the lamellae of the upper half group Articulation points the same distance from the swivel axis have and are further away from the swivel axis than the articulation points on the slats of the lower half group, with these also within the group the distance of the articulation points from the hinge or Swivel axis is the same. Both groups are through one Rod connected so that simultaneous adjustment, but with different angles. At a such air outlet are the injector jets within every group with every setting of the air outlet parallel to each other, but depending on the setting of the air outlet the injector jets of the two groups diverge more or less.

Besonders einfache Anlenkungsstellen sind beispielsweise Bohrungen in den Stirnflächen der jeweiligen Lamelle.Particularly simple articulation points are, for example Bores in the end faces of the respective slats.

Da die am weitesten außen liegenden Lamellen auf ihrer Außenseite keinen Nachbarn haben, genügt es, wenn diese Lamellen von einer Planseite begrenzt sind. Sie sind gleichsam die Hälfte der Lamellen, die sich in der Mitte der Öffnung befinden.Because the outermost slats on have no neighbors on the outside, it suffices if these slats are limited by one side of the sheet. they are as it were half of the slats in the middle the opening.

Die Figuren 1 und 2 zeigen einen Luftauslaß 1 mit einem eine Öffnung 2 umgrenzenden Rahmen 3 und mit in der Öffnung 2 des Rahmens 3 schwenkbar gelagerten Lamellen 4. Die Lamellen 4 sind in dem Rahmen 3 um zueinander parallelen Scharnierachsen 5 schwenkbar gelagert und innerhalb der Öffnung 2 äquidistant verteilt, so daß zwischen benachbarten Lamellen 4 jeweils eine schlitzförmige, längliche Düse 6 entsteht.Figures 1 and 2 show an air outlet 1 with an opening 2 bordering frame 3 and with in the Opening 2 of the frame 3 hinged slats 4th The slats 4 are parallel to each other in the frame 3 Hinge axes 5 pivoted and within the opening 2 equidistantly distributed, so that between adjacent slats 4 each have a slot-shaped, elongated Nozzle 6 is created.

Der Rahmen 3 ist beispielsweise ein Blechstanzformteil, bei dem an den Ecken miteinander verbundene Längskanten 7 ausgebildet sind, die die Öffnung 2 umgrenzen. An den Innenseiten von drei Längskanten 7 sind Leisten 8 aufgekantet, die in dieselbe Richtung weisen und einen sich aus dem Rahmen 3 erhebenden Kragen bilden, der bis auf eine Seite die Öffnung 2 umgibt. An den Ecken, an denen die Leisten 8 zusammenstoßen, sind sie stoffschlüssig miteinander verbunden.The frame 3 is, for example, a stamped sheet metal part, with the longitudinal edges joined together at the corners 7 are formed which delimit the opening 2. On the inside of three longitudinal edges 7 are strips 8 edged, pointing in the same direction and one form from the frame 3 uplifting collar that up surrounds the opening 2 on one side. At the corners where the strips 8 collide, they are integral connected with each other.

Die Lamellen 4 haben die in Figur 3 vergrößert dargestellte Seitenansicht. Wie zu erkennen ist, sind sie etwa keilförmig, wobei das Querschnittsprofil über ihre gesamte Länge konstant ist. Jede Lamelle 4 ist von zwei Längsseiten 9 und 11 sowie einer Basisseite 12 begrenzt. Die beiden Längsseiten 9 und 11 sind an einem Scheitel 13, der zu der Längsachse der Lamelle 4 parallel liegt, einstückig miteinander verbunden. Ausgehend von diesem Scheitel 13 divergieren die beiden Längsseiten 9 und 11 in Richtung auf die Basisseite 12, wo sie an parallel zu der Längsachse der Lamelle verlaufenden Stirnkanten 14 bzw. 15 enden. An diesen Stirnkanten 14 und 15 gehen die Längsseiten 9 und 11 einstückig in die Basisseite oder Basisfläche 12 über, die ein Ausschnitt aus einer Zylinderfläche ist.The slats 4 have the enlarged shown in Figure 3 Side view. As can be seen, they are about wedge-shaped, with the cross-sectional profile over its entire Length is constant. Each lamella 4 is from two long sides 9 and 11 and a base page 12 limited. The two long sides 9 and 11 are at a vertex 13, the is parallel to the longitudinal axis of the lamella 4, in one piece connected with each other. Starting from this vertex 13 the two long sides 9 and 11 diverge in the direction to the base side 12, where it is parallel to the longitudinal axis the end edges 14 and 15 of the slat end up. At these end edges 14 and 15 the long sides go 9 and 11 in one piece in the base side or base surface 12 above, which is a section of a cylindrical surface is.

Die Längsseiten 9 und 11, sowie die Basisseite 12 sind in die Außenseiten eines entsprechenden Aluminiumstrangpreßprofils, das im Innern mit einer über die Länge der Lamelle durchgehenden Kammer 16 versehen ist, deren Außenkontur etwa der Außenkontur der Lamelle 4 folgt, so daß an allen Stellen näherungsweise die gleiche Wandstärke vorhanden ist. Die Basisseite 12 bildet eine in Längsrichtung der Lamelle 4 durchgehende Nut oder Rinne, die seitlich und in Richtung von der Lamelle 4 weg offen ist.The long sides 9 and 11, as well as the base side 12 are in the outer sides of a corresponding extruded aluminum profile, that inside with a length the slat continuous chamber 16 is provided, the The outer contour follows approximately the outer contour of the lamella 4 that approximately the same wall thickness at all points is available. The base side 12 forms one in the longitudinal direction the slat 4 continuous groove or channel is open laterally and in the direction away from the lamella 4.

An den Stirnseiten ist jede Lamelle 4 durch eine Stirnfläche bildende Abdeckplatte 17 verschlossen. Die Abdeckplatte 17 ist auf der betreffenden Stirnseite der Lamelle 4 befestigt, wozu im Strangpreßprofil der Lamelle 4 in der Nähe des Scheitels 13 eine durchgehende Nut 18 enthalten ist, deren freies Stirnende eine Öffnung bildet. Auf der der Kammer 16 zugekehrten Innenseite der Basisseite sind zwei leistenförmige Fortsätze 19 angeformt, die zwischen sich eine weitere von einer Nut 21 definierte Öffnung begrenzen. Mit diesen Öffnungen 18 und 21 fluchten entsprechende Bohrungen in der Platte 17, so daß hierdurch Schrauben oder Niete in die Nuten 18 und 21 eingesetzt werden können, um die Platte 17 an der Stirnfläche zu halten.At the end faces, each lamella 4 is by one End plate forming cover plate 17 closed. The Cover plate 17 is on the relevant end face Lamella 4 attached, what in the extruded profile of the slat 4 a continuous groove 18 near the apex 13 is included, the free end of which forms an opening. On the inside of the base side facing the chamber 16 are two strip-shaped extensions 19 formed, the another defined by a groove 21 between them Limit opening. Align with these openings 18 and 21 corresponding holes in the plate 17, so that this Screws or rivets inserted in the grooves 18 and 21 can be to the plate 17 on the end face too hold.

Um die Lamelle 4 in dem Rahmen 3 schwenkbar zu lagern, kann der in der Nut 18 eingesetzte Niet an seinem Kopf einen kurzen zu der Nut 18 der koaxialen zylindrischen Zapfen tragen, der als Lagerzapfen in eine entsprechende Bohrung in dem Rahmen 3 einzusetzen ist, um das Schwenklager oder Scharnier 5 zu bilden.To pivot the slat 4 in the frame 3, can the rivet used in the groove 18 on his Head a short to the groove 18 of the coaxial cylindrical Wear the pin, which as a bearing pin in a corresponding Hole in the frame 3 is to use the Form pivot bearing or hinge 5.

Im montierten Zustand ragen die Lamellen 4 mit ihrer Basisseite 12 über eine eine Ebene hinaus, die von dem Rand des Kragens aus den Leisten 8 definiert ist. Der Raum vor der Basisseite 12 ist deswegen nach der Seite nicht von dem Kragen abgeschattet.In the assembled state, the slats 4 protrude with their Base page 12 beyond a level that of the Edge of the collar is defined from the strips 8. The space before the base page 12 is therefore not after the page shadowed by the collar.

Die Platte 17 enthält ferner eine Vielzahl von Lagerbohrungen 22, deren Mittelpunkte auf einer Geraden 23 liegen, die einen durch den Scheitel 13 laufende Winkelhalbierende eines Winkels ist, der von den beiden Seitenflächen 9 und 11 in der Zeichenebene der Figur 3 aufgespannt wird. Diese Bohrungen 22 sind Anlenkungsstellen einer Verstelleinrichtung für die Lamellen 4.The plate 17 also includes a plurality of bearing bores 22, whose centers on a straight line 23 lie, a bisector running through the apex 13 is an angle from the two side faces 9 and 11 spanned in the drawing plane of Figure 3 becomes. These holes 22 are articulation points an adjusting device for the slats 4.

Bezogen auf die Darstellung von Figur 1 bzw. Figur 2, sind am oberen und am unteren Rand der Öffnung 2 Lamellen 24 vorgesehen, die sich im Querschnitt von den Lamellen 4 insofern unterscheiden, als sie gleichsam jeweils die Hälfte einer Lamelle 4 sind. Wie Figur 4 erkennen läßt, bestehen sie lediglich aus einer konvex gekrümmten streifenförmigen Platte 25, deren Gestalt den Seitenflächen 9 oder 11 entspricht. Neben einer Kante 26 der Platte 25 befindet sich eine Nut, die, wenn die Platte 25 deckungsgleich zu der betreffenden Wand der Lamelle 4 aufgelegt ist, mit der Nut 18 fluchtet. Eine weitere Nut 28 ist an der Rückseite der Platte 25 in der Nähe ihrer Vorderkante 29 ausgebildet und dient der Befestigung einer Deckplatte 31. Die Deckplatte 31 enthält im übrigen Lagerbohrungen 32, die in ihrer relativen Lage zu der konvexen Platte 25 und der Nut 27 der Lage der Lagerbohrungen 22 relativ zu der Nut 18 entsprechen.Based on the representation of Figure 1 or Figure 2, are 2 slats at the top and bottom of the opening 24 is provided, which is in cross section from the slats 4th to the extent that they, as it were, each Half of a slat 4 are. As can be seen in FIG. 4, they only consist of a convexly curved strip-shaped Plate 25, the shape of the side surfaces 9th or 11 corresponds. In addition to an edge 26 of the plate 25 there is a groove which, when the plate 25 is congruent placed on the wall of the slat 4 in question is aligned with the groove 18. Another groove 28 is on the back of the plate 25 near its front edge 29 designed and used to attach a cover plate 31. The cover plate 31 also contains bearing holes 32, which are in their relative position to the convex plate 25 and the groove 27 of the position of the bearing bores 22 relative to correspond to the groove 18.

Die Lamelle 24 ist in den Rahmen 3 derart eingebaut, daß ihre konvexe Fläche einer Lamelle 4 benachbart ist, während die konkave Seite zu der benachbarten Kante 7 des Rahmens 3 zeigt.The lamella 24 is installed in the frame 3 in such a way that its convex surface is adjacent to a lamella 4, while the concave side to the adjacent edge 7 of the Frame 3 shows.

Um die Wurfrichtung des Luftauslasses verändern zu können, sind, wie Figur 2 zeigt, sämtliche Lamellen 4 und die beiden Lamellen 24 über eine Verstellstange 33 miteinander gekoppelt. Die Verstellstange 33 ist eine gerade flache Stange, an der im Abstand der Lamellen 4 voneinander bzw. Lamellen 4 und 24 voneinander Zapfen 34 befestigt sind. Die Zapfen 34 werden in eine entsprechende Bohrung 22 bzw. 32 eingesteckt. Um unterschiedliche Verstellwinkel zu erzielen, ist bei dem Ausführungsbeispiel nach Figur 2 die Verstellstange bei der obersten Lamelle 24 an jener Lagerbohrung 32 angelenkt, die am weitesten von der Nut 18 entfernt liegt. Die unmittelbar darunter befindliche Lamelle 4 ist mit der Verstellstange 33 über eine Lagerbohrung 22 verbunden, die um ein Loch näher an dem Scheitel 13 liegt. Die zweite Lamelle 4, von oben gesehen, ist über die nächste, dem Scheitel 13 benachbarte Lagerbohrung 22 mit der Verstellstange 33 gekoppelt. Für die nachfolgenden Lamellen 4 gilt sinngemäß das gleiche, insofern, als die Verbindungsstelle zwischen der Verstellstange 33 und der betreffenden Lamelle 4 jeweils um ein Loch weiter in Richtung auf die Scharnierachse 5 verschoben ist. Bei der unteren Lamelle 24 schließlich liegt die Anlenkungsstelle der Verstellstange 33 am dichtesten an der Scharnierachse 5, verglichen mit allen übrigen Lamellen 4 bzw. 24.To change the throwing direction of the air outlet can, as Figure 2 shows, all the slats 4 and the two slats 24 with one another via an adjusting rod 33 coupled. The adjustment rod 33 is a straight one flat rod, on the distance of the slats 4 from each other or lamellae 4 and 24 from each other pins 34 are attached are. The pins 34 are in a corresponding Hole 22 or 32 inserted. By different adjustment angles to achieve is in the embodiment according to Figure 2, the adjustment rod at the top slat 24 hinged to that bearing bore 32, the farthest is located away from the groove 18. The immediately below located slat 4 is with the adjusting rod 33 a bearing bore 22 connected to a hole closer to the apex 13 lies. The second slat 4, from above seen, is over the next, the vertex 13 adjacent Bearing bore 22 coupled to the adjusting rod 33. For the following slats 4 apply mutatis mutandis the same, insofar as the connection point between the adjustment rod 33 and the respective slat 4 by one Hole moved further towards hinge axis 5 is. Finally, in the lower lamella 24 Articulation point of the adjusting rod 33 closest to the hinge axis 5, compared to all other slats 4 or 24.

Wenn der insoweit beschriebene Luftauslaß 1 an einer entsprechenden Auslaßöffnung eines schematisch veranschaulichten Luftkanals oder Klimakanals 35 befestigt wird, streicht die Luft wie durch einen Pfeil 36 schematisch dargestellt, von der Rückseite her durch den Luftauslaß 1. Die Luft strömt die einzelnen Lamellen 4 vom Scheitel 13 her an und gelangt durch die zwischen den benachbarten Lamellen 4 bzw. 4 und 24 definierten schlitzförmigen Luftdüsen 6 in den betreffenden, zu belüftenden Raum. Bei entsprechender Bemessung der Lagerbohrungen 22 und der Verstellstange 33 liegen in der in Figur 2 gezeigten Stellung die Lamellen 4 und 24 so, daß die Achsen der zwischen ihnen definierten Düsen 6 parallel zueinander ausgerichtet sind und auf der durch die Öffnung 2 definierten Ebene senkrecht stehen.If the air outlet 1 described so far at a corresponding outlet opening of a schematically illustrated Air duct or air duct 35 is attached, strokes the air as schematically by an arrow 36 shown, from the rear through the air outlet 1st The air flows through the individual fins 4 from the apex 13 forth and through the between the neighboring ones Slats 4 or 4 and 24 defined slot-shaped Air nozzles 6 in the relevant room to be ventilated. At appropriate dimensioning of the bearing bores 22 and Adjustment rod 33 are in that shown in Figure 2 Position the slats 4 and 24 so that the axes of the between them defined nozzles 6 parallel to each other are aligned and on the one defined by the opening 2 Stand vertically.

Da die Luft mit verhältnismäßig großer Strömungsgeschwindigkeit aus den schlitzförmigen Düsen 6 austritt und durch die keilförmige Gestalt der Lamellen 4 in einzelne voneinander getrennte Luftstrahlen aufgeteilt ist, strömt von der Seite Raumluft ungehindert zwischen die aus den Düsen 6 austretende Luft. Die aus den Düsen 6 austretende Injektorluft saugt die Raumluft an, um sie sodann vermischt mit der Injektorluft im Raum zu verteilen. Das Zuströmen der Raumluft erfolgt senkrecht zu der Zeichenebene von Figur 2 von beiden Seiten des Luftauslasses 1 her. An der zylinderförmig gekrümmten Basisseite 12 wird die Raumluft wie durch Pfeile 37 in Figur 3 angedeutet, in Richtung parallel zu der Luftströmung der aus den Düsen 6 austretenden Injektorstrahlen umgelenkt. Bei der Einstellung des Luftauslasses 1, wie in Figur 2 gezeigt, kommt ein verhältnismäßig schmaler Öffnungswinkel des Gesamtluftstromes, der sich aus der Injektorluft und aus der Raumluft zusammensetzt, zustande. Außerdem strömt der Luftstrom im wesentlichen senkrecht von der durch die Öffnung 3 definierten Ebene weg.Because the air flows at a relatively high speed emerges from the slot-shaped nozzles 6 and by the wedge-shaped shape of the slats 4 in individual separate air jets are divided, air flows freely between them from the side air emerging from the nozzles 6. The emerging from the nozzles 6 Injector air draws in the room air and then it mixed with the injector air to distribute in the room. The The air flows in perpendicular to the plane of the drawing of Figure 2 from both sides of the air outlet 1st forth. On the cylindrical base side 12 is curved the room air as indicated by arrows 37 in FIG. 3, in Direction parallel to the air flow from the nozzles 6 emerging injector jets deflected. When hiring of the air outlet 1, as shown in Figure 2, comes a relatively narrow opening angle of the total air flow, which results from the injector air and from the Room air. In addition, the streams Airflow essentially perpendicular from that through the Opening 3 defined level away.

Wenn eine andere Strahlrichtung gewünscht ist, wird die Verstellstange 33 nach unten bewegt, wodurch entsprechend die Lamellen 4 und 24 nach unten schwenken. Da die Anlenkungsstellen der Verstellstange 33 von der Lage der Lamelle 4 bzw. 24 innerhalb der Öffnung 3 abhängig ist, schwenkt jede der Lamellen 4 bzw. 24 um einen typischen Winkel. Der Verstellwinkel ändert sich kontinuierlich von oben nach unten und ist bei der oberen Lamelle 24 am kleinsten, während der bei der unteren Lamelle 24 am größten ist, da hier die Anlenkungsstelle der Verstellstange 33 am dichtesten an der Scharnierachse 5 liegt, die mit der Achse der Nut 18 koaxial ist. Die aus dem Luftauslaß 1 austretenden Injektorluftstrahlen sind jetzt nicht mehr zueinander parallel, sondern sie divergieren, was zu einer entsprechenden Divergenz des entstehenden Gesamtluftstroms führt. Außerdem strahlt der Luftauslaß jetzt mit einer stark nach unten gerichteten Komponente.If a different beam direction is desired, the adjustment rod 33 moves down, which accordingly Swivel slats 4 and 24 downwards. Since the Articulation points of the adjusting rod 33 from the position of the Slat 4 or 24 is dependent within the opening 3, pivots each of the slats 4 and 24 around a typical Angle. The adjustment angle changes continuously from top down and is at the top lamella 24 smallest, while at the lower lamella 24 largest is because here the articulation point of the adjustment rod 33 is closest to the hinge axis 5, the is coaxial with the axis of the groove 18. The one from the air outlet 1 escaping injector air jets are now no longer parallel to each other, but they diverge, resulting in a corresponding divergence of the emerging Total air flow leads. The air outlet also shines now with a strongly downward component.

Infolge der konvexen Gestalt der Längsseiten 9 und 11 bzw. 25 ändert sich die in Höhenrichtung gemessene Weite der schlitzförmigen Düsen 6 auch in der verschwenkten Stellung kaum, weil die freie Kante 15 der darüber befindlichen Lamelle 4 einer Stelle an der oberen Längsseite 9 gegenüberliegt, die näher an dem Scheitel 13 liegt und damit einen geringeren Abstand von der Winkelhalbierenden 23 hat. Die aus dem Luftauslaß 1 austretende Injektorluftmenge bleibt innerhalb bestimmter Grenzen unabhängig von der Winkeleinstellung der Lamellen 4 bzw. 24.Due to the convex shape of the long sides 9 and 11 or 25, the width measured in the height direction changes the slit-shaped nozzles 6 also in the pivoted Position hardly, because the free edge 15 of the one above Slat 4 of a point on the upper long side 9 opposite, which is closer to the apex 13 and thus a smaller distance from the bisector 23 has. The quantity of injector air emerging from the air outlet 1 remains independent within certain limits on the angle setting of slats 4 or 24.

Anstatt wie bei den Figuren 1 bis 5 sämtliche Lamellen 4 und 24 gleichzeitig und gleichsinnig zu verstellen, besteht auch die Möglichkeit, wie in Figur 6 gezeigt, mehrere, beispielsweise 2, Verstellstangen 33a und 33b zu verwenden, um Gruppen von Lamellen zu bilden, die gemeinsam verschwenkt werden. So sind bei dem Ausführungsbeispiel nach Figur 4 die oberen beiden Lamellen 4 und die obere Lamelle 24 über die Verstellstange 33a und die unteren beiden Lamellen 4 sowie die untere Lamelle 24 über die ihnen gemeinsame Verstellstange 33b gekuppelt. Dadurch lassen sich die betreffenden Gruppen von Lamellen individuell einstellen.Instead of all slats as in Figures 1 to 5 4 and 24 can be adjusted simultaneously and in the same direction, there is also the possibility, as shown in FIG. 6, several, for example 2, adjustment rods 33a and 33b use to form groups of slats that are common be pivoted. So are in the embodiment according to Figure 4, the top two slats 4 and upper lamella 24 via the adjusting rod 33a and lower two slats 4 and the lower slat 24 over the common adjustment rod 33b coupled. Thereby the groups of slats in question can be customized to adjust.

Schließlich zeigt Figur 7 ein Ausführungsbeispiel eines Luftauslasses, der gleichsam aus 4 Luftauslässen gemäß Figur 1 so kombiniert ist, daß die enthaltenen Lamellen 4 bzw. 24 lediglich gruppenweise zueinander parallel sind. Insgesamt sind 4 Gruppen von Lamellen gebildet, von denen jede ein Viertel der Gesamtöffnung 3 des Luftauslasses ausfüllt und jede zu einer Kante der quadratischen Öffnung 3 parallel ist.Finally, Figure 7 shows an embodiment an air outlet that consists of 4 air outlets 1 is combined so that the contained Slats 4 and 24 only in groups to each other are parallel. There are a total of 4 groups of slats formed, each a quarter of the total opening 3 of the air outlet and each to an edge of the square opening 3 is parallel.

Im übrigen ist der Aufbau und die Betätigung der Lamellen sinngemäß wie vorher im Zusammenhang mit den Figuren 1 bis 5 beschrieben.Otherwise, the construction and operation of the Slats analogously as before in connection with the Figures 1 to 5 described.
