Description

Die Erfindung betrifft einen Qellauslaß aus einem runden oder eckigen Rahmenrohr mit zumindest einem Quellauslaß-Gitter, sowie ein verfahren zu seiner Herstellung.The invention relates to a spring outlet from a round or square frame tube with at least one spring outlet grille, and to a method for its production.

Unter Quellauslässen werden solche Luftzuführelemente verstanden, welche in der Regel aus einem runden oder eckigen Zuführrohr bestehen, in deren Wand normalerweise einfache Lamellen oder Schlitzgitter eingesetzt sind. Derartige Rohre werden beispielsweise auch von einer Decke bis zum Fußboden gezogen, so daß dieser Fußboden selbst den Abschluß des Zuführsystems bildet. Der Rückstau von Luft bewirkt dann den Austritt der Zuluft durch die entsprechenden Schlitz- oder Lamellengitter in einen Raum.Swell outlets are understood to mean those air supply elements which generally consist of a round or angular supply pipe, in the wall of which simple lamellae or slotted gratings are normally used. Such pipes are also drawn from a ceiling to the floor, for example, so that this floor itself forms the end of the feed system. The backflow of air then causes the supply air to escape through the corresponding slotted or louvre grilles into a room.

Bislang werden derartige Quellauslässe in runder, halbrunder oder anderer Ausführung gefertigt, wobei die Teile sehr große Abmessungen aufweisen. Quellauslässe besitzen mitunter einen Durchmesser von 1.250 mm und 2.000 mm Höhe. Es ist verständlich, daß sowohl bei der Fertigung wie auch der Montage hier erhebliche Probleme auftreten. Das größte Problem ist der Versand derartiger Quellauslässe, wobei insbesondere die Sperrigkeit diesen Versand verteuert und erschwert.So far, such source outlets have been manufactured in a round, semicircular or other design, the parts having very large dimensions. Spring outlets sometimes have a diameter of 1,250 mm and 2,000 mm height. It is understandable that considerable problems occur here both in manufacture and in assembly. The biggest problem is the dispatch of such source outlets, the bulkiness in particular making this dispatch more expensive and more difficult.

Aus der DE-A 36 05 539 ist beispielsweise eine Vorrichtung zum Zuführen eines weitgehend gleichmäßigen Luftstromes in einen Raum mit einem Lochblech bekannt, vor den ein Tuch aus einem Feingewebe angeordnet ist. Dieses Tuch hat eine vergleichmäßigte Wirkung auf den durch das Lochblech austretenden Luftstrom. Ein derartiges Lochblech zusammen mit dem Tuch ist in eine Nut eines Rahmens eingesetzt und bildet kein selbständiges Einbauteil. Ferner trifft hier der Luftstrom direkt auf die Rückseite des Lochbleches auf, so daß es auf der Austrittseite des Lochbleches zu starken Turbulenzen kommt. Diese Turbulenzen müssen durch das Tuch vergleichmäßigt werden. Für eine Umlenkung eines Luftstromes aus einer Förderrichtung innerhalb eines Rahmenrohres durch ein in Förderrichtung angeordnetes Lochblech ist diese Vorrichtung ungeeignet.DE-A 36 05 539, for example, discloses a device for supplying a largely uniform air flow into a room with a perforated plate, in front of which a cloth made of a fine fabric is arranged. This cloth has an even effect on the air flow exiting through the perforated plate. Such a perforated plate together with the cloth is inserted into a groove in a frame and does not form an independent installation part. Furthermore, the air flow hits the back of the perforated plate directly, so that there is strong turbulence on the outlet side of the perforated plate. This turbulence must be evened out by the cloth. This device is unsuitable for deflecting an air flow from a conveying direction within a frame tube through a perforated plate arranged in the conveying direction.

Der Erfinder hat sich zum Ziel gesetzt, den Quellauslaß sowohl das Herstellen wie auch das Montieren derartiger Luftauslässe zu verbessern und insbesondere zu verbilligen.The inventor has set itself the goal of improving and in particular making the air outlet both the manufacture and the assembly of such air outlets less expensive.

Zur Lösung dieser Aufgabe führt, daß das Quellauslaß-Gitter aus einem mit einem Abdeckrahmen verbundenen Lochblech und einem Gleichrichter besteht, welcher aus einer mit Querschlitzen versehenen Rückwand mit einem davon abgekanteten Seitenstreifen und Deckstreifen besteht, über die die Rückwand zu dem Lochblech mit Abstand gehalten und verbunden ist.To solve this problem, the source outlet grille consists of a perforated plate connected to a cover frame and a rectifier, which consists of a rear wall provided with transverse slots with a bevelled side strip and cover strip, via which the rear wall is held at a distance from the perforated plate and connected is.

Der wesentliche Vorteil der Erfindung liegt darin, daß jetzt nicht mehr ganze Quellauslässe in den oben genannten Abmessungen verschickt werden müssen, sondern daß beispielsweise Lüftungsrohre für vorhandene Lüftungskanäle entweder in eckiger oder runder Form auf die gewünschte Distanz zum Fußboden heruntergezogen werden und aus diesen Lüftungskanälen bzw. Rahmenrohren entsprechende Öffnungen ausgeschnitten werden, in die dann die Standard-Quellauslaß-Gitter eingesetzt werden.The main advantage of the invention is that it is no longer necessary to send entire source outlets in the dimensions mentioned above, but that For example, ventilation pipes for existing ventilation ducts are pulled down either in a square or round shape to the desired distance from the floor, and corresponding openings are cut out of these ventilation ducts or frame tubes, into which the standard source outlet grilles are then inserted.

Wesentlich ist dabei, daß das Quellauslaß-Gitter aus einem Lochblech und einem Gleichrichter vorgefertigt wird. Da das Loch von einem Abdeckrahmen umgeben sein sollte, hat es sich als günstig erwiesen, von dem Lochblech den entsprechenden Abdeckrahmen abzukanten.It is essential that the source outlet grille is prefabricated from a perforated plate and a rectifier. Since the hole should be surrounded by a cover frame, it has proven to be advantageous to bend the corresponding cover frame from the perforated plate.

Dabei kann es sich um einen ganz oder teilweise umlaufenden Abdeckrahmen handeln. Bei der Montage dient dieser Abdeckrahmen zur Festlegung des Quellauslaß-Gitters an dem Rahmenrohr, wobei die Festlegung durch Nieten oder Schrauben erfolgt.It can be a completely or partially surrounding cover frame. During assembly, this cover frame is used to fix the source outlet grille to the frame tube, the fixing being done by rivets or screws.

Zur Herstellung des Gleichrichters werden aus einer Rückwand Querschlitze ausgestanzt, wobei die Stanzung dann so erfolgt, daß gleich aus den Querschlitzen ausgebogene Lamellen als Gleichrichter stehenbleiben. Dies vereinfacht die Herstellung wesentlich. Von der Rückwand werden dann Seitenstreifen bzw. obere und untere Deckstreifen abgekantet, über die der Gleichrichter mit dem Abdeckrahmen oder dem Lochblech zu einem gesamten Quellauslaß-Gitter verbunden wird. Die Verbindung kann durch Nieten, Schweißen, Kleben od. dgl. erfolgen.To produce the rectifier, transverse slots are punched out of a rear wall, the punching then taking place in such a way that lamellae bent out of the transverse slots remain as rectifiers. This significantly simplifies production. Side strips or upper and lower cover strips are then folded from the rear wall, via which the rectifier is connected to the cover frame or the perforated plate to form an entire source outlet grille. The connection can be made by riveting, welding, gluing or the like.

Auf diese Weise lassen sich insbesondere Quellauslaß-Gitter mit einer Höhe von 65 mm, 115 mm, 215 mm und 315 mm sowie einer Länge von 425 mm, 625 mm, 825 mm, 1025 mm und 1225 mm herstellen. Selbstverständlich sind auch Zwischengrößen denkbar.In this way, source outlet grilles with a height of 65 mm, 115 mm, 215 mm and 315 mm and a length of 425 mm, 625 mm, 825 mm, 1025 mm and 1225 mm can be produced. Of course, intermediate sizes are also conceivable.

Diese Quellauslaß-Gitter lassen sich dann direkt in runde oder eckige Rahmenrohre einsetzen, wobei in der Regel eine Mehrzahl solcher Quellauslaß-Gitter Anwendung findet. Hat z.B. ein Rahmenrohr einen größeren Durchmesser, z.B. 1250 mm, so können mehrere Quellauslaß-Gitter (4 bis 8 Stück) aufeinanderfolgend bzw. radial eingesetzt werden. Je nach Wunsch kann durch den Einsatz entsprechender Quellauslaß-Gitter die Luftstrahlführung beeinflußt werden, beispielsweise von einem Rundstrahl bis hin zu einem in einer einzelnen Richtung gerichteten Strahl.These source outlet grilles can then be inserted directly into round or square frame tubes, a plurality of such source outlet grilles generally being used. If, for example, a frame tube has a larger diameter, for example 1250 mm, several source outlet grilles (4 to 8 pieces) can be used in succession or radially. Depending on the requirements, the use of appropriate source outlet grilles can influence the air jet guidance, for example from an omnidirectional jet to a jet directed in a single direction.

Ggfs. können an den Lamellen noch schmale Stege angebracht sein, welche der Stabilisierung und Erhöhung des Festwiderstandes dienen. Dadurch wird die Zuluft im Lüftungskanal gleichmäßig verteilt und eine Vergleichmäßigung des Austritts der Zuluft erreicht.If necessary. can still be attached to the slats narrow webs, which serve to stabilize and increase the fixed resistance. As a result, the supply air is evenly distributed in the ventilation duct and the outlet air is evened out.

Ferner ist es auch möglich, hinter das Lochblech eine Filtermatte einzusetzen, welche nicht nur der Luftfilterung, sondern auch einer zusätzlichen Gleichrichtung dient.Furthermore, it is also possible to use a filter mat behind the perforated plate, which not only serves for air filtering but also for additional rectification.

Im Rahmen der Erfindung liegt ebenfalls, daß der Gleichrichter nicht als gleichmäßiger rechteckiger Kasten ausgebildet ist, sondern eine Steigung von einem oberen Deckstreifen zu einem unteren Deckstreifen aufweist. Dies wird durch eine entsprechende unterschiedliche Breite der Deckstreifen gewährleistet. Dadurch entsteht eine gewisse Querschnittsverengung im Inneren des Rahmenrohres, so daß die Luft etwas gestaut wird und der Austritt der Zuluft durch die Rückwand bzw. das Lochblech erleichtert ist.It is also within the scope of the invention that the rectifier is not designed as a uniform rectangular box, but has an incline from an upper cover strip to a lower cover strip. This is guaranteed by a correspondingly different width of the cover strips. This creates a certain cross-sectional constriction in the interior of the frame tube, so that the air is somewhat stowed and the outlet of the supply air through the rear wall or the perforated plate is facilitated.

Die Quellauslaß-Gitter können aus Aluminium, Kunststoff od. dgl. hergestellt sein oder in verzinkter Ausfertigung geliefert werden. Es besteht aber auch die Möglichkeit, sie nach Montage anschließend zu lackieren.The source outlet grille can be made of aluminum, plastic or the like or can be supplied in a galvanized version. But there is also the option of painting them after installation.

Gemäß den Figuren 6 bis 9 besteht ein erfindungsgemäßer Quellauslaß Q1 - Q4 aus einem runden oder rechteckigen Rahmenrohr 1 bzw. 2, welche jeweils einen Innenraum I umschließen. Nicht gezeigt sind diese Rohre mit entsprechenden Luftzuführungssystemen verbunden. Zum Auslassen von Zuluft in einen Raum sind Quellauslaß-Gitter 3a - 3d vorgesehen, welche in die entsprechenden Rahmenrohre 1 bzw. 2 eingesetzt sind.According to FIGS. 6 to 9, a source outlet Q1-Q4 according to the invention consists of a round or rectangular frame tube 1 or 2, which each enclose an interior space I. These pipes are not shown connected to corresponding air supply systems. Source outlet grilles 3a - 3d are provided for discharging supply air into a room and are inserted into the corresponding frame tubes 1 and 2, respectively.

Dabei schlägt ein Abdeckrahmen 4a bzw. 4b von außen her an das Rahmenrohr 1 bzw. 2 an.A cover frame 4a or 4b strikes the frame tube 1 or 2 from the outside.

Gemäß Figur 1 umschließt der Abdeckrahmen 4 ein Lochblech 5. Im Abdeckrahmen 4 sind Löcher 6 zur Aufnahme von beispielsweise Nieten erkennbar, mit denen der Abdeckrahmen 4 mit dem Rahmenrohr 1 bzw. 2 verbunden ist.According to Figure 1, the cover frame 4 encloses a perforated plate 5. In the cover frame 4 holes 6 can be seen for receiving rivets, for example, with which the cover frame 4 is connected to the frame tube 1 or 2.

Gemäß Figur 3 kann das Lochblech 5b und der Abdeckrahmen 4b plan ausgebildet sein, wie dies die untere Abbildung in Figur 3 zeigt. In der oberen Abbildung ist allerdings zu erkennen, daß das Lochblech 5a auch eine dem Rahmenrohr 1 nachempfundene Krümmung aufweisen kann. Entsprechend sind dann auch die Stirnkanten des Abdeckrahmens 4a gekrümmt. Die Seitenstreifen des Abdeckrahmens 4a bleiben dagegen langgestreckt.According to Figure 3, the perforated plate 5b and the cover frame 4b can be flat, as shown in the lower figure in Figure 3. In the upper figure, however, it can be seen that the perforated plate 5a can also have a curvature based on the frame tube 1. The end edges of the cover frame 4a are then also curved accordingly. The side strips of the cover frame 4a, however, remain elongated.

Vom Innenraum I her ist an den Abdeckrahmen 4 bzw. das Lochblech 5 ein Gleichrichter 7 angesetzt. Dieser Gleichrichter 7 besteht aus einem umlaufenden Rahmen mit Seitenstreifen 8 und einem oberen Deckstreifen 9 sowie einem unteren Deckstreifen 10. Wie in Figur 3 erkennbar, paßt sich der obere Deckstreifen und der untere Deckstreifen 9 bzw. 10 selbstverständlich der Krümmung des Lochblechs 5a an.A rectifier 7 is attached to the cover frame 4 or the perforated plate 5 from the interior I. This rectifier 7 consists of a peripheral frame with side strips 8 and an upper cover strip 9 and a lower cover strip 10. As can be seen in FIG. 3, the upper cover strip and the lower cover strip 9 or 10 naturally adapt to the curvature of the perforated plate 5a.

Seitenstreifen 8 sowie Deckstreifen 9 und 10 sind von einer Rückwand 11 abgekantet, welche Querschlitze 12 besitzt. Diese sind besonders gut in Figur 5 erkennbar. Den Querschlitzen 12 sind nach innen, d.h. in dem Bereich des umlaufenden Rahmens Lamellen 13 zugeordnet, welche insbesondere der Gleichrichtung der Luftströmung dienen.Side strips 8 and cover strips 9 and 10 are folded from a rear wall 11 which has transverse slots 12. These can be seen particularly well in FIG. 5. The transverse slots 12 are assigned inwards, ie in the area of the peripheral frame, lamellae 13, which serve in particular to rectify the air flow.

In dem Ausführungsbeispiel gemäß den Figuren 4 und 5 ist erkennbar, daß ein unterer Deckstreifen 10a breiter ausgebildet ist als der obere Deckstreifen 9. Hierdurch ergibt sich eine gewisse Anstellung der Lamellen 13 gegenüber dem Lochblech 5, so daß eine schräg gerichtete Luftströmung aus dem Lochblech 5 austreten kann. Des weiteren verengt sich der Querschnitt des Innenraumes I durch ein derartiges Quellauslaß-Gitter 3b bzw. 3d, so daß ein gewisser Luftstau entsteht und die Luft durch die Querschlitze 12 gedrückt wird. Dies kann zu einer Verbesserung der Luftführung beitragen.In the embodiment according to FIGS. 4 and 5 it can be seen that a lower cover strip 10a is wider than the upper cover strip 9. This results in a certain adjustment of the slats 13 relative to the perforated plate 5, so that an obliquely directed air flow from the perforated plate 5 can leak. Furthermore, the cross section of the interior I is narrowed by such a source outlet grille 3b or 3d, so that a certain air jam occurs and the air is forced through the transverse slots 12. This can help improve airflow.

Erfindungsgemäß soll es noch möglich sein, vor das Lochblech 5 eine Filtermatte 14 einzusetzen, wie dies beispielhaft nur in Figur 4 angedeutet ist. Diese Filtermatte 14 dient sowohl der Luftfilterung als auch einer zusätzlichen Gleichrichtung. Aus technischen Erfordernissen ist dies jedoch nicht unbedingt notwendig.According to the invention, it should still be possible to use a filter mat 14 in front of the perforated plate 5, as is only indicated by way of example in FIG. 4. This filter mat 14 is used both for air filtering and an additional rectification. However, this is not absolutely necessary due to technical requirements.

Derartige Quellauslaß-Gitter 3 können direkt in runde oder eckige Rahmenrohre 1 bzw. 2 eingesetzt werden, wobei an den Einsatz mehrerer Quellauslaß-Gitter 3 gedacht ist, wie dies insbesondere in Figur 6-9 dargestellt wird. Es können auch eine Vielzahl derartiger Quellauslaß-Gitter 3 in Längsrichtung der Rahmenrohre 1 bzw. 2 aufeinanderfolgend angeordnet werden. Ihre Anordnung kann ferner so erfolgen, daß ein Luftstrahl nach einer Seite oder rundherum austritt, so daß eine Rundstrahlung erreicht wird. Es kann aber auch genügen, wenn die Strahlung durch die entsprechende Anordnung der Quellauslaß-Gitter 3 nur halbrund erfolgt.Such source outlet grille 3 can be used directly in round or square frame tubes 1 and 2, with the use of several source outlet grille 3 is intended, as is shown in particular in Figure 6-9. A large number of such source outlet grids 3 can also be arranged in succession in the longitudinal direction of the frame tubes 1 or 2. They can also be arranged in such a way that an air jet emerges to one side or all around, so that omnidirectional radiation is achieved. However, it may also be sufficient if the radiation is only semicircular due to the corresponding arrangement of the source outlet grids 3.

Die Herstellung und Montage derartiger Quellauslässe Q erfolgt folgendermaßen:Such source outlets Q are manufactured and installed as follows:

Das Quellauslaß-Gitter 3 besteht bevorzugt aus zwei Teilen, nämlich einmal dem Lochblech 5 mit Abdeckrahmen 4 sowie zum zweiten aus dem Gleichrichter 7. Lochblech 5 und Abdeckrahmen 4 sind bevorzugt aus einem Stück geformt, wobei ein Ausstanzen der Löcher des Lochblechs 5 erfolgt und ein Abkanten des Abdeckrahmens 4. Aus dem Abdeckrahmen 4 werden die entsprechenden Löcher 6 für die Befestigungsmittel an den Rahmenrohren 1 bzw. 2 erzeugt.The source outlet grille 3 preferably consists of two parts, namely the perforated plate 5 with cover frame 4 and the second from the rectifier 7. Perforated plate 5 and cover frame 4 are preferably formed from one piece, punching out the holes in the perforated plate 5 and a Folding the cover frame 4. The corresponding holes 6 for the fastening means on the frame tubes 1 and 2 are produced from the cover frame 4.

Auch der Gleichrichter 7 wird aus einem Stück hergestellt. Hierzu werden aus der Rückwand 11 die Querschlitze 12 gestanzt, was dadurch geschieht, daß die Stanzung so erfolgt, daß gleichzeitig die Lamellen 13 nach hinten abgebogen werden können. Zur Stabilisierung und zur Erhöhung des Festwiderstandes sind an den Lamellen 13 noch schmale Stege 15 angebracht, wie dies in Figur 2 nur angedeutet ist. Dadurch wird die Zuluft über die gesamte Gitterfläche gleichmäßig verteilt.The rectifier 7 is also made from one piece. For this purpose, the transverse slots 12 are punched out of the rear wall 11, which is done in that the punching is carried out in such a way that the slats 13 can be bent backwards at the same time. To stabilize and to increase the fixed resistance, narrow webs 15 are also attached to the slats 13, as is only indicated in FIG. 2. This means that the supply air is evenly distributed over the entire grille area.

Von der Rückwand 11 werden die entsprechenden Seitenstreifen 8 sowie oberen Deckstreifen 9 und unteren Deckstreifen 10 abgekantet, so daß nunmehr der Gleichrichter 7 auf das Lochblech 5 bzw. den Abdeckrahmen 4 aufgesetzt werden kann. Dort wird er entweder angeschraubt, angenietet oder angeklebt.The corresponding side strips 8 and upper cover strips 9 and lower cover strips 10 are folded from the rear wall 11, so that the rectifier 7 can now be placed on the perforated plate 5 or the cover frame 4. There it is either screwed, riveted or glued.

Bei der Montage eines Quellauslasses werden die vorhandenen Lüftungskanäle bzw. deren Rahmenrohre 1 und 2 auf die gewünschte Distanz zum Fußboden heruntergezogen. Aus diesen Rahmenrohren 1 bzw. 2 müssen dann nur entsprechend den Maßen der Quellauslaß-Gitter 3 Öffnungen ausgeschnitten werden, in die eben diese Quellauslaß-Gitter 3 eingesetzt werden. Die Festlegung der Quellauslaß-Gitter 3 erfolgt beispielsweise durch entsprechende Nieten, welche die Löcher 6 durchdringen. Ferner können die Gitter 3 auch mittels traversen Balken in die runden bzw. eckigen Rahmenrohre 1 bzw. 2 eingesetzt werden.

Figure imgb0001
When installing a source outlet, the existing ventilation ducts or their frame tubes 1 and 2 are pulled down to the desired distance from the floor. From these frame tubes 1 and 2 then need only according to the dimensions of the source outlet grille 3rd Openings are cut into which these source outlet grids 3 are inserted. The source outlet grille 3 is fixed, for example, by appropriate rivets which penetrate the holes 6. Furthermore, the grids 3 can also be inserted into the round or angular frame tubes 1 or 2 by means of cross beams.
