Düse für Belüftungs- oder Klimaanlagen, insbesondere in KraftfahrzeuginnenräumenNozzle for ventilation or air conditioning systems, especially in motor vehicle interiors
Die Erfindung betrifft eine Düse für Belüftungs- oder Klimaanlagen, insbesondere in Kraftfahrzeuginnenräumen, mit einem Gehäuse, das in einer Luftdurchtrittsöffnung eine Anzahl zu einer Jalousie parallel miteinander ver¬ bundene Lamellen verstellbar und in Strömungsrichtung vor der Luftdurchtrittsöffnung eine Luftklappe schwenk- beweglich verstellbar aufweist und mit einem gemeinsamen Bedienelement für Lamellen und Luftklappe ausgerüstet ist.The invention relates to a nozzle for ventilation or air conditioning systems, in particular in motor vehicle interiors, with a housing which can adjust a number of slats connected to a blind in parallel in an air passage opening and which has an air flap which can be pivoted and moved in the flow direction in front of the air passage opening and with a common control element for slats and air flap is equipped.
Bei einer bekannten Düse (DE 37 19 837) sind im Luftka- nal des Düsengehäuses hintereinander zwischen einerIn a known nozzle (DE 37 19 837) there are one behind the other in the air duct of the nozzle housing
Offen- und einer Schließstellung verschwenkbare Klappen und eine durch verschwenkbare Lamellen gebildete Jalou¬ sie angeordnet. Bei dieser Düse ermöglicht ein auf einer Lamelle aufgesetzter Schieber Abεchwenkungen der Lamel- len und bei Querbewegungen des Schiebers Abschwenkungen der Klappen. Abgesehen davon, daß die Schieberbewegungen undeffinierte Verstellungen von Lamellen und Klappen zu¬ lassen, wirken die Klappen auch nur als Sperrglieder auf die Zuluft .Open and a closed position pivotable flaps and a Jalou¬ sie formed by pivotable slats arranged. With this nozzle, a slide mounted on a lamella allows the lamellae to be pivoted away and the flaps to be pivoted away in the event of transverse movement of the slide. In addition to the fact that the slide movements allow undefined adjustments of the slats and flaps, the flaps also act only as blocking elements on the supply air.
Es ist Aufgabe der Erfindung bei einer Luftdüεe obiger Gattung die Ausrichtbewegungen und das Volumen der Ab¬ luft exakt regelbar zu machen und zusätzliche Funktionen für die Luftströmung zu schaffen.It is an object of the invention to make the alignment movements and the volume of the exhaust air precisely controllable in an air nozzle of the above type and to create additional functions for the air flow.
Erfindungsgemäß ist diese Aufgabe gelöst durch ein am oder im Düsengehäuse drehbar ausgebildetes Bedienele¬ ment, das über einen Kurventrieb mit den Lamellen und über ein Hebelgetriebe mit einer einer weiteren Luft¬ durchtrittsöffnung in der Düsengehäusewandung zugeord¬ neten Klappe gekoppelt ist. Gemäß bevorzugter Ausbild¬ ung, ist das Bedienelement durch ein auf einem düsenge- häusefesten Zapfen drehbar angeordneten Bedienrad gebil¬ det. Auf diese Weise ist die Zuluft durch Betätigen eines einzigen Bedienelements vermittels der Klappe wahlweise an die eine oder andere von zwei im Düsenge¬ häuse vorhandenen Lύftdurchtrittsöffnungen bzw. gleich- zeitig an die beiden Luftdurchtrittsöffnungen leitbar und durch die vermittels eines einεtückigen oder unter¬ teilten Koppelgliedes miteinander verbundenen Lamellen im Bereich einer Luftdurchtrittsöffnung zusätzlich richtungsveränderbar sowie mehr oder weniger absperrbar. Außerdem bietet die Drehbeweglichkeit des Bedienelements klapper- und schwingungsfreie Fixierungen und Betätig¬ ungen von Lamellen und Klappe mit deffinierten Drehmo¬ menten.According to the invention, this object is achieved by a control element which is designed to be rotatable on or in the nozzle housing and which has a cam mechanism with the lamellae and is coupled via a lever mechanism with a flap assigned to a further air passage opening in the nozzle housing wall. According to a preferred embodiment, the operating element is formed by an operating wheel rotatably arranged on a pin fixed to the nozzle housing. In this way, the supply air can be directed by actuating a single control element by means of the flap either to one or the other of two air passage openings in the nozzle housing or simultaneously to the two air passage openings and to one another by means of an integral or divided coupling element connected slats in the area of an air passage opening can also be changed in direction and more or less shut off. In addition, the rotational mobility of the operating element offers rattle-free and vibration-free fixations and actuations of lamellae and flap with defined torques.

Zweckmäßig weiεen zu Drehbewegungen deε Kulissenradeε Bedienrad und Kulisεenrad konzentrisch im Abstand von- einander Verzahnungen auf, die mit einem im Düsengehäuse ortsfest ausgebildeten Ritzel kraftschlüssig kämmen. Es versteht sich, daß das Kulisεenrad wahlweise durch einen kreisrunden Radkörper oder beliebig anderweitig, z.B. durch im wesentlichen streifenförmigen Formkörper mit an einem Ende angeordneten Verbreiterungen gebildet sein kann. Bevorzugt erεtreckt εich die Zahnung deε Kuliεεen- rades an einem Ringabschnitt im Bereich der Verbreiter¬ ungen, während die Zahnung des Bedienradeε an einem Ringbund umlaufend auεgebildet iεt.For rotary movements of the sliding wheel, the operating wheel and the sliding wheel expediently have toothings which are concentrically spaced from one another and mesh with a pinion which is designed to be stationary in the nozzle housing. It goes without saying that the link wheel can be formed either by a circular wheel body or in any other way, for example by essentially strip-shaped bodies with widenings arranged at one end can. The toothing of the sliding wheel preferably extends on a ring section in the area of the widened portions, while the toothing on the operating wheel extends circumferentially on a ring collar.

In den Fig. 1 biε 4 ist mit 1 das Gehäuse einer Luftdüse bezeichnet, das z.B. im Armaturenbrett 2 einer Kraft¬ fahrzeugkarosserie (nicht gezeigt) einεetzbar iεt. Im Bereich einer ersten Luftdurchtrittsöffnung 3 sind im Gehäuεe 1 fünf Lamellen 4, von denen nur eine darge- εtellt iεt, um Achsen 9 εchwenkbar gelagert, die beim Auεführungsbeispiel durch die beiden Koppelgliedab¬ schnitte 10,11 (Fig. 14) miteinander in Verbindung stehen. Die Koppelgliedabschnitte 10,11 sind hierzu auf an den Lamellen 4 angeformten Zapfen 12 und 13 aufge¬ steckt. Der Zapfen 13 der gezeigten Lamelle 4 ist in axialer Richtung verlängert und durch eine ringab- εchnittεförmige Auεneh ung 1 ' ' in der Wandung 1 ' des Gehäuεes 1 hindurchgeführt und in eine Kulisεennut 14 eines Kuliεεenradeε 15 eingebracht.

In einer Seitenfläche 25 weist daε Bedienrad 20 eine Kuliεεennut 26 auf, in die ein am Gehäuse 1 bei 27 angelenkter Doppelhebel 28 mit einem auf seinem He¬ belarm 28' angeordneten Stift 29 eintaucht, über eine Stift-Schlitzverbindung 30 steht der andere Hebelarm 28'' des Doppelhebelε 28 mit einem Hebelarm 31' einer Klappe 31 in Wirkverbindung, die mit einem Bund 32 in einer Auεnehmung 33 deε Gehäuses 1 εchwenkbewegiich gelagert ist und einer zweiten Luftdurchtrittsöffnung 34 zugeordnet ist.1 to 4, 1 denotes the housing of an air nozzle, which can be used, for example, in the dashboard 2 of a motor vehicle body (not shown). In the area of a first air passage opening 3 there are five lamellae 4 in the housing 1, only one of which is shown, which can be pivoted about axes 9, which in the exemplary embodiment are connected to one another by the two coupling link sections 10, 11 (FIG. 14) . For this purpose, the coupling link sections 10, 11 are attached to pins 12 and 13 formed on the lamellae 4. The pin 13 of the lamella 4 shown is extended in the axial direction and by a ring Section-shaped recess 1 '' is passed through the wall 1 'of the housing 1 and inserted into a slot 14 of a slot wheel 15. The roller wheel 15 is supported with an annular collar 16 in a recess 17 of the operating wheel 20 on an annular collar 18 of the operating wheel 20 which is rotatably mounted on a pin 19 fixed to the housing. The link wheel 15 is provided with a toothing 21 and the control wheel 20 is provided with a further toothing 22 at a distance from the toothing 21, both of which mesh with a pinion 24 mounted on a pin 23 fixed to the housing. In a side surface 25, the control wheel 20 has a slot 26 into which a double lever 28 articulated on the housing 1 at 27 with a pin 29 arranged on its lever arm 28 'is immersed. The other lever arm 28' is located via a pin-slot connection 30 'of the double lever 28 with a lever arm 31' of a flap 31 in operative connection, which is mounted pivotably with a collar 32 in a recess 33 of the housing 1 and is assigned to a second air passage opening 34.
Zum Verεtändmε der Funktion der Luftdüεe lεt davon aus¬ zugehen, daß daε Bedienrad 20 zunächεt die Stellung der Fig. 1 einnimmt. In dieεer Stellung iεt die Kuliεεennut 26 in eine Endεtellung gebracht und über den Stift 29 ist der Doppelhebel 28 in Uhrzeigerdrehrichtung m eine Endεtellung geεchwenkt. Dabei wird über die Stift- Schlitzverbindung 30 die als Verεchlußglied dienende Klappe 31 für die zweite Luftauεtrittεöffnung 34 in Schließεtellung gehalten. Gleichzeitig iεt über dasTo understand the function of the air nozzle, it can be assumed that the control wheel 20 initially assumes the position of FIG. 1. In this position, the slide groove 26 is brought into an end position and the double lever 28 is pivoted in the clockwise direction of rotation in an end position via the pin 29. The flap 31 serving as a closure member for the second air outlet opening 34 is held in the closed position via the pin-slot connection 30. At the same time it is about that

Die Lamellen 4 lassen eine be- hinderungsarme ausgerichtete Abströmung der Zuluft zu. Ein Verbringen der Lamellen 4 in verschiedene Schwenk¬ stellungen über die Dauer deε Verbleibε der Klappe 31 in der Schließεtellung (Fig.l), ermöglicht der zur Dreh- achεe deε Bedienradeε konzentrische Verlauf deε Ab- εchnittε 26' der Kulissennut 26.Pinion 24 and the two toothings 21, 22 move the culinary wheel 15 into the end position shown. The slats 4 are brought into the open position by means of the slot 14 and pin 13. The lamellae 4 allow an outflow of the supply air which is aligned with little hindrance. Bringing the slats 4 into different pivot positions over the duration of the flap 31 remaining in the closed position (FIG. 1) enables the section 26 ′ of the slotted groove 26, which is concentric with the axis of rotation of the operating wheel, to be made.
Durch Drehen deε Bedienungεradeε 20 in Uhrzeigerdreh¬ richtung (Fig.2), iεt der Doppelhebel 28 bei Eintritt deε Stifteε 29 in d'en radial im größerem Abstand ver- laufenden Abschnitt 26'' der Kulissennut 26 geringfügig abgeschwenkt und die Klappe 31 (Fig.2) in eine Offen¬ stellung für die zweite Luftdurchtrittεöffnung 34 ge¬ bracht. Daε Kuliεsenrad 15 iεt gleichzeitig in die Stel¬ lung der Fig. 2 bewegt und bewirkt eine Abεchwenkung der Lamellen 4, etwa in die dargestellte Stellung. Es ver- εteht εich, daß durch mehr oder weniger weiteε Verdrehen deε Bedienradeε 20 die Klappe 31 mehr oder weniger ge- εchwenkt wird und die Lamellen 4 die erεte Luftdurch¬ trittεöffnung mehr oder weniger weit frei geben und da- ~ bei eine Auεrichtung der Luftεtrömung bewirken.By turning the control wheel 20 in the clockwise direction of rotation (FIG. 2), the double lever 28 when the pin 29 enters the section 26 ″ of the link groove 26 which runs radially at a greater distance is pivoted slightly and the flap 31 (FIG .2) brought into an open position for the second air passage opening 34. The pusher wheel 15 simultaneously moves into the position of FIG. 2 and causes the slats 4 to pivot, for example into the position shown. It comparable εteht εich that by more or less weiteε twisting the flap 31 is more or less frequently used εchwenkt deε Bedienradeε 20 and the fins 4, the erεte Luftdurch¬ trittεöffnung give more or less far-free and DA ~ at a Auεrichtung the Luftεtrömung cause.
Durch weiteres Drehen deε Bedienradeε 20 in Uhrzeiger¬ drehrichtung (Fig.3), kann über den Doppelhebel 28 die Klappe 31 in die Offenεtellung für die zweite Luftdurch- trittεöffnung 34 gebracht werden, wodurch die Zuluft über dieεe daε Gehäuεe 1 verlaεεen kann. Gleichzeitig εind durch das Kuliεεenrad 15 die Lamellen 4 in ihre Schließstellung bewegt und ein Luftauεtritt über die erεte Luftdurchtrittεöffnung 3 verhindert.By further turning the control wheel 20 in the clockwise direction of rotation (FIG. 3), the flap 31 can be brought into the open position for the second air passage opening 34 by means of the double lever 28, as a result of which the supply air can leave the housing 1. At the same time, the slats 4 are moved into their closed position by the sliding wheel 15 and air leakage through the first air passage opening 3 is prevented.
Eine behinderungsfreie Betätigung der Lamellen 4 ist möglich, weil die Koppelglieder 10,11 durch miteinander verbundene Teilabschnitte (Fig. 14,15) gebildet εind. A disability-free actuation of the slats 4 is possible because the coupling links 10, 11 are formed by interconnected partial sections (Fig. 14, 15).
