Description

Die vorliegende Erfindung bezieht sich auf ein Element für Lüftungsjalousien, bei welchem zwei sich in Längsrichtung erstreckende, auf Abstand gehaltene Schalen mit ihren Randzonen unter Bildung eines kastenförmigen Querschnittes miteinander verbunden sind, während die Randkanten benachbarter Elemente durch Verschwenken um ihre Längsachse in einander wechselweise überdeckende Stellungen zu bringen sind.The present invention relates to an element for ventilation blinds in which two longitudinally extending, spaced-apart shells are connected to one another with their edge zones to form a box-shaped cross section, while the edge edges of adjacent elements are pivoted about their longitudinal axis into mutually overlapping positions are to be brought.

Elemente für Lüftungsjalousien dieser Art sind nach der DE-PS 17 79 255 bekannt. Dabei finden als Schalen parallel zueinander verlaufende, geradflächige Bleche Anwendung, von denen das dem zu belüftenden Raum zugewendete Blech gelocht ist, so daß sich in Verbindung mit einem zwischen den Schalen befindlichen, schallschluckenden Element zugleich eine Schallisolierung ergibt.Elements for ventilation blinds of this type are known from DE-PS 17 79 255. Here are used as shells parallel to each other, straight-sided sheets, of which the sheet facing the room to be ventilated is perforated, so that in connection with a sound-absorbing element located between the shells there is also sound insulation.

Dieses bekannte Element läßt sich innerhalb begrenzter Abmessungen einsetzen. Bei zunehmenden Größen der Lüftungsöffnungen kommt es jedoch zu Durchbiegungen der Schalen, weil infolge der Füllung mit einem schallschluckenden Material Versteifungen der Elemente. nicht möglich sind. Darüber hinaus wird selbst in der vollen öffnungsstellung der Elemente ein sehr großer Teil des Gesamtquerschnittes wegen auftretender Strömungswirbel nicht für die Belüftung genutzt.This known element can be used within limited dimensions. With increasing sizes of the ventilation openings, however, the shells deflect because the elements are stiffened due to the filling with a sound-absorbing material. are not possible. In addition, even in the full open position of the elements, a very large part of the total cross section is not used for ventilation due to flow turbulence.

Der Erfindung liegt die Aufgabe zugrunde, ein Element der einleitend benannten Art dahingehend weiterzuentwickeln, daß es sich einerseits bei stärkeren mechanischen Belastungen, wie sie vor allem, jedoch nicht ausschließlich, durch größere Abmessungen ergeben, verwenden läßt, und daß andererseits ein größerer Anteil des Lüftungsquerschnittes für die Strömung in der öffnungsstellung der Elemente nutzbar gemacht werden kann.The invention has for its object to further develop an element of the type mentioned in such a way that it can be used on the one hand with greater mechanical loads, such as result primarily, but not exclusively, from larger dimensions, and on the other hand, that a larger proportion of the ventilation cross-section can be used for the flow in the open position of the elements.

Diese Aufgabenstellung wird durch die Erfindung, wie sie in den Patentansprüchen gekennzeichnet ist, gelöst.This problem is solved by the invention as characterized in the claims.

Man kommt auf diese Weise zu einem Lüftungselement von besonderem mechanischen Widerstand, weil die miteinander verbundenen Schalen eine in erheblichem Maße gesteigerte Festigkeit aufweisen. Dies gelingt, ohne zusätzliche Versteifungsmittel zwischen den Schalen oder außerhalb derselben anwenden zu müssen, so daß einerseits die hervorragende Schallisolierung erhalben bleibt, und daß andererseits durch den Verzicht auf äußere Rippen oder dergleichen eine nachteilige Beeinflussung der Strömung unterbleibt. Letztere wird vielmehr durch die besondere Querschnittsform des neuen Elementes in der Weise günstig beeinflußt, daß die bei den bekannt gewesenen Elementen auftretenden Wirbelbildungen weitgehend vermieden werden. Bereits hierdurch kommt eine schalldärmende Wirkung zustande, da die eindringende Luft weniger Strömunysgeräusche verursacht.In this way, a ventilation element of particular mechanical resistance is obtained because the interconnected shells have a considerably increased strength. This can be done without additional stiffeners between the shells or to have to use them outside, so that on the one hand the excellent sound insulation is retained, and on the other hand the absence of external ribs or the like prevents the flow from being adversely affected. The latter is rather favorably influenced by the special cross-sectional shape of the new element in such a way that the vortex formation occurring in the known elements is largely avoided. This already results in a sound-absorbing effect, since the penetrating air causes less noise from the flow.

Die geradflächige Ausbildung der der Abströmseite zukehrbaren Schale ermöglicht eine besonders wirkungsvoll Verspannung zwischen den beiden Schalen, indem sie gewölbte Schale wie eine Sehne gespannt hält. Zweckmäßig ist die geradflächige Schale gelocht. Man erhält somit in Bezug auf die gekrümmt ausgeführte Schale einen Schwinungsresonator, der entsprechend den unterschiedlichen Abständen der beiden Schalen voneinander auf unterschiedliche Schallfrequenzen anspricht und hierdurch ein besonders bereitsbandiges Schallfrequenispektrum zu dämpfen vermag.The straight surface design of the shell which can be turned towards the outflow side enables particularly effective tensioning between the two shells by keeping the curved shell taut like a tendon. The straight bowl is expediently perforated. In relation to the curved shell, a vibration resonator is thus obtained which responds to different sound frequencies in accordance with the different distances of the two shells from one another and is thereby able to dampen a particularly already banded sound frequency spectrum.

Darüber hinaus läßt sich, wie es an sich bekannt gewesen ist, schalldämmendes Material zwischen den beiden Schalen verwenden, das dann eine besonders gute Wirkung entfaltet, wenn bei aus Metall, beispielsweise aus Leichtmetall, hergstellten Schalen das schallabsorbierende Material eine Hohlraumstruktur aufweist.In addition, as has been known per se, sound-absorbing material can be used between the two shells, which then has a particularly good effect if the sound-absorbing material has a cavity structure in shells made of metal, for example light metal.

Die Festigkeit des neuen Elementes wird weiterhin dadurch gesteigert, daß die Schalen selbst von Lagerfunktionen entlastet werden. Zu diesem Zwecke sind die Stirnseiten der Elemente mit ihnen angepaßten Blechen fest verschlossen. Bei derartigen Blechen können die Stirnseiten überragende Abschnitte vorteilhaft ein Gelenk für eine gemeinsame Betätigungsstange aufweisen, mit der sich mehrere Elemente der gleichen Lüftjalousie zugleich verstellen lassen, während die Bleche im Bereich der Stirnseiten um ortsfeste Achsen verschwenkbar sind. Die Betätigungsstange kann bei entsprechendem Abstand der beiden Schwenklager mit geringer Stellkraft ausgelöst werden, so daß sie sich vor allem auch für die Einstellung der Elemente auf einen bestimmten öffnungsquerschnitt und gegebenenfalls auch für Regelungszwecke vorsehen läßt.The strength of the new element is further increased in that the shells themselves are relieved of storage functions. For this purpose, the end faces of the elements are tightly closed with sheet metal adapted to them. In the case of sheets of this type, the sections projecting from the end faces can advantageously have a joint for a common actuating rod, with which several elements of the same ventilating blind can be adjusted at the same time, while the sheets are pivotable in the area of the end faces about stationary axes. The actuating rod can be triggered with a small actuating force at a corresponding distance between the two pivot bearings, so that it can be provided above all for the setting of the elements to a specific opening cross section and, if appropriate, also for control purposes.

Die Lüftungsanforderungen sehen häufig einen vollständigen, luft- und regendichten Abschluß der Lüftungsjalousie vor. Um dies bei den erfindungsgemäßen Elementen zu gewährleisten, ist eine ihrer Randzonen mit einer äußeren Gummikante versehen, die mit der anderen Randzone des jeweils benachbarten Elementes in der Schließstellung eine Dichtung bildet.The ventilation requirements often provide for a complete, airtight and rainproof closure of the ventilation blind. In order to ensure this in the elements according to the invention, one of its edge zones is provided with an outer rubber edge which forms a seal with the other edge zone of the respectively adjacent element in the closed position.

Um die erwähnte Dichtung wirksam werden zu lassen, ist es von Vorteil, wenn die Gummikante mit Spannung zur Anlage gebracht werden kann. Sie kann eine wirkungsvolle Dichtungskraft sowie auch eine langlebige Funktion dadurch erlangen, daß sie etwa parallel zur Richtung der gekrümmten Schale in Richtung auf deren dickeren Querschnittsbereich verläuft, um mit einer Verlängerung der gekrümmten Schale des benachbarten Elementes unter flachem Winkel in einen dichtenden Eingriff zu gelangen. Je flacher der genannte Winkel wird, umso mehr vergrößert sich dabei die Dichtungsfläche zwischen der Gummikante und der Verlängerung der gekrümmten Schale des benachbarten Elementes.In order to make the seal mentioned effective, it is advantageous if the rubber edge can be brought into contact with tension. It can achieve an effective sealing force as well as a long-lasting function in that it runs approximately parallel to the direction of the curved shell in the direction of its thicker cross-sectional area in order to come into sealing engagement with an extension of the curved shell of the adjacent element at a flat angle. The flatter the angle mentioned, the more the sealing surface between the rubber edge and the extension of the curved shell of the adjacent element increases.

Zum weiteren Schutz der erwähnten Dichtung sowie auch zur Verbesserung der Festigkeit ist die vorerwähnte Verlängerung mit einem zur Querschnittsmitte hin gerichteten Abschnitt ausgebildet, der in der Schließstellung die Gummikante des benachbarten Elementes überdeckt.To further protect the above-mentioned seal and also to improve the strength, the aforementioned extension is formed with a section directed towards the cross-sectional center, which in the closed position covers the rubber edge of the adjacent element.

Für den Aufbau des neuen Elementes eignen sich in besonderem Maße zwei getrennt hergestellte Schalen, die durch Kraftschluß miteinander verbunden sind, indem sich randseitige Verriegelungen besitzen. Zur weiteren Veranschaulichung der Erfindung wird auf die sich auf ein Ausführungsbeispiel beziehenden Zeichnungen Bezug genommen. Darin zeigen:

  • Figur 1 das erfindungsgemäße Element in seiner Schließstellung,
  • Figur 2 eine Mehrfachanordnung einer Lüftungsjalousie in öffnungsstellung der Einzelemente und
  • Figur 3 eine Ansicht entsprechend der Schnittlinie III-III der Figur 2.
For the construction of the new element, two separately manufactured shells are particularly suitable, which are connected to one another by frictional engagement by having locking devices on the edge. To further illustrate the invention, reference is made to the drawings relating to an exemplary embodiment. In it show:
  • FIG. 1 shows the element according to the invention in its closed position,
  • Figure 2 shows a multiple arrangement of a ventilation blind in the open position of the individual elements and
  • 3 shows a view along the section line III-III of FIG.

Der Querschnitt 1 zeigt gemäß den Figuren 1 und 2 eine deutlich unsymmetrische Ausbildung, wobei auf die ortsfeste Schwenkachse 21, wie in Figur 2 angegeben, Bezug genommen ist. Insbesondere erkennt man einen vergrößerten Querschnittsbereich 12 sowie einen gegenüberliegenden verjüngten Querschnittsbereich 22. Die gekrümmte Schale 2 sowie die geradflächige Schale 3 begrenzen den genannten Querschnitt unter Bildung der erwähnten Form. Die Anordung ist dabei so getroffen, daß das Element in Richtung des Schwenkpfeiles 23 um die ortsfeste Achse 21 in seine Schließstellung gebracht werden kann. Dabei kehrt es seine gekrümmte Schale 2 der Einströmrichtung 20 zu. Die geradflächige Schale 3 ist weiterhin gelocht, wie die Öffnungen 24 in einem Ausschnittbereich erkennen lassen. BEi Ausführung der Öffnungen über die gesamte Fläche der Schale 3 ergeben sich die erwähnten Schwingungsresonatoren für unterschiedliche Schallfrequenzen. Das schallschluckende Material 4 ist,wie der Ausschnitt in Figur 1 erkennen läßt, von poröser Struktur.According to FIGS. 1 and 2, cross section 1 shows a clearly asymmetrical design, reference being made to the fixed pivot axis 21, as indicated in FIG. 2. In particular, one can see an enlarged cross-sectional area 12 and an opposing tapered cross-sectional area 22. The curved shell 2 and the straight-faced shell 3 delimit the above-mentioned cross-section to form the shape mentioned. The arrangement is such that the element can be brought into its closed position in the direction of the pivot arrow 23 about the stationary axis 21. It turns its curved shell 2 towards the inflow direction 20. The straight-sided shell 3 is still perforated, as can be seen from the openings 24 in a cutout area. When the openings are made over the entire surface of the shell 3, the aforementioned vibration resonators result for different sound frequencies. The sound-absorbing material 4, as can be seen from the detail in FIG. 1, has a porous structure.

Die Stirnseiten 5 der Elemente sind mit Blechen verschlossen, deren überragende Abschnitte 6 an eine gemeinsame Betätigungsstange 7 für sämtliche Elemente einer Lüftungsjalousie angelenkt sind. Außerdem tragen die Bleche Lager für die Achsen 21.The end faces 5 of the elements are closed with metal sheets, the projecting sections 6 of which are articulated to a common actuating rod 7 for all elements of a ventilation blind. The sheets also have bearings for the axles 21.

Die Randzonen 10 sind mit einer Gummikante 8 ausgeführt, welche mit der Randzone 9 des benachbarten Elementes eine Dichtung bildet.The edge zones 10 are designed with a rubber edge 8 which forms a seal with the edge zone 9 of the adjacent element.

Diese ist, wie bereits erwähnt, besonders wirkungsvoll, wenn sich die Gummikante 8 in Richtung 11 parallel zum Anstieg der gekrümmten Schale 2 erstreckt, so daß ein flacher Dichtungswinkel zwischen der Gummikante 8 und der Randzone 9 besteht. Die Randzone 9 ergibt sich als eine Verlängerung der gekrümmten Schale 2 über die Randkante 13 hinaus. Diese Verlängerung geht in den abgewinkelten Abschnitt 14 über, der die Gummikante 8 des benachbarten Elementes in seiner Schließstellung überdeckt.As already mentioned, this is particularly effective if the rubber edge 8 extends in the direction 11 parallel to the rise of the curved shell 2, so that there is a flat sealing angle between the rubber edge 8 and the edge zone 9. The edge zone 9 results as an extension of the curved shell 2 beyond the edge 13. This extension merges into the angled section 14, which covers the rubber edge 8 of the adjacent element in its closed position.

Figur 1 zeigt weiter, daß die Schalen 2 und 3 miteinander verriegelt sind. Zu diesem Zweck besteht einerseits die Verriegelung 15, 16 und andererseits die Verriegelung 17, 18. Auf diese Weise läßt sich die Verriegelung unter einem Kraftschluß vornehmen, der einer Deformation des Elementes bei der Einwirkung äußerer Kräfte entgegenwirkt.Figure 1 further shows that the shells 2 and 3 are locked together. For this purpose, there is on the one hand the lock 15, 16 and on the other hand the lock 17, 18. In this way, the locking can be carried out with a force fit, which counteracts a deformation of the element when exposed to external forces.
