Description

Die Erfindung betrifft einen Deckenauslaß, insbesondere einen quadratischen Deckenauslaß für das Einblasen von Zuluft aus einem Luftleitsystem in einen Raum, sowie ein Verfahren zu seiner Herstellung.The invention relates to a ceiling outlet, in particular a square ceiling outlet for blowing supply air from an air guidance system into a room, and a method for its production.

Deckenauslässe diesere Art sind bekannt und auf dem Markt vielfach angeboten. Diese Auslässe unterscheiden sich vor allem in der Größe und in der Anordnung der den Luftstrom leitenden Lamellen.Ceiling outlets of this type are known and widely offered on the market. These outlets differ primarily in the size and arrangement of the fins that conduct the air flow.

Es gibt beispielsweise Auslässe mit wenigen und breiten Lamellen oder andere mit vielen und dafür schmalen Lamellen. Des weiteren sind Auslässe bekannt, deren Lamellen fest angeordnet sind, während andere Lamellen besitzen, welche verstellbar sind. In ihrer Grundkonzeption, insbesondere in ihrer Bauweise, sind sich jedoch sowohl die verstellbaren als auch die fest angeordneten Auslässe ähnlich. Dabei sind vor allem die Auslässe mit relativ breiten Einströmflächen aus Einzelstücken gefertigt.There are, for example, outlets with a few and wide fins or others with many and therefore narrow fins. Furthermore, outlets are known, the slats of which are fixedly arranged, while others have slats which are adjustable. In their basic concept, especially in their construction, both the adjustable and the fixed outlets are similar. Above all, the outlets with relatively wide inflow surfaces are made from individual pieces.

Die Einzelstücke bestehen aus einem Rahmen und den einzelnen, die Lamellen bildenden Einblasringen. Solche Einblasringe werden durch Zusammenschweißen von einzeln geformten, insbesondere gestanzten Stücken hergestellt. Die zusammengeschweißten Einblasringe werden dann in einem weiteren Arbeitsschritt entweder wieder durch Schweißung oder aber durch Schraubung od. dgl. innerhalb des Rahmens befestigt. Ein solches Verfahren ist nicht nur umständlich, zeitraubend und somit kostenintensiv, sondern es ist auch umweltbelastend und energieverschwendend.The individual pieces consist of a frame and the individual blowing rings that form the lamellae. Such blowing rings are produced by welding individually shaped, in particular stamped pieces. The welded blow-in rings are then fastened again in the work step either by welding or by screwing or the like. Within the frame. Such a process is not only cumbersome, time-consuming and therefore costly, but it is also polluting and wastes energy.

Umweltbelastend ist das Verfahren nicht nur durch die beim Schweißen entstehenden Gase, sondern vor allem auch durch die Art der zu wählenden Lackierung, die durch das Vorhandensein von Ecken, Kanten und Schweißnähten nur möglich ist.The process is not only polluting due to the gases generated during welding, but above all also due to the type of paint to be selected, which is only possible due to the presence of corners, edges and weld seams.

Energieverschwendend ist das Verfahren einerseits durch die für die Schweißapparate notwendige Energie und zweitens durch die Energie für die bei diesen Arbeiten vorgeschriebenen Absaugeinrichtungen.The process is energy-wasting on the one hand due to the energy required for the welding equipment and secondly due to the energy required for the suction devices prescribed for this work.

Neben den wirtschaftlichen Gesichtspunkten wegen der hohen Arbeitskosten sind vor allem auch die Umweltbelastung und die Energieverschwendung Faktoren, die in einer Zeit einer erhöhten Sensibilisierung für die Umwelt verbesserungswürdig sind.In addition to the economic aspects due to the high labor costs, environmental pollution and energy waste are factors that need to be improved in a time of increased awareness of the environment.

Der Erfinder hat sich zur Aufgabe gestellt, einen Deckenauslaß zu schaffen, der die Vorteile der auf dem Markt befindlichen Auslässe dieser Art besitzt, jedoch in einem Verfahren hergestellt werden kann, welches sich kostengünstiger, umweltschonender und energiesparender auswirkt.The inventor has set himself the task of creating a ceiling outlet which has the advantages of the outlets of this type on the market, but which can be produced in a process which has a more cost-effective, environmentally friendly and energy-saving effect.

Zur Lösung dieser Aufgabe führt, daß von einem Blech, einer Stahlblechplatte od. dgl. Luftleitbleche in einem Winkel bevorzugt nach vier Seiten abragen.To achieve this object, air baffles protrude from a sheet, a sheet steel plate or the like at an angle, preferably on four sides.

Einem solchen Blech sind dann noch randseitig Randstreifen durch Abkantung angeformt.Edge strips of this type are then formed on the edge by bending.

Der Vorteil eines solchen Deckenauslasses besteht darin, daß er aus einem einzigen Stück ohne Schweißungen, Klebungen od. dgl. hergestellt werden kann.The advantage of such a ceiling outlet is that it can be made from a single piece without welding, gluing or the like.

Zur Herstellung wird ein Stahlblech, ein Blech od. dgl. bzw. eine Platte eines gewünschten Materials benötigt, welche in ihren Konturen der Form des späteren Deckenauslasses entspricht, wobei randseitig noch so viel Material zugelassen wird, wie für die spätere Abkantung der Randstreifen notwendig ist.For the production a steel sheet, a sheet or the like. Or a plate of a desired material is required, which corresponds in its contours to the shape of the later ceiling outlet, with as much material being permitted on the edge as is necessary for the later folding of the edge strips .

Dieses Blech wird dann mittels eines besonderen und speziellen Fertigungsverfahrens, insbesondere durch Stanzung, geschlitzt und ausgeeckt. Die Konturen der Schlitze umschreiben dabei zumindest drei Seiten der Form der späteren abgewinkelten Luftleitbleche. Luftleitbleche dieser Art haben bevorzugt eine etwa gleichschenklig trapezförmige Kontur. Die Größe der Auseckung richtet sich nach der Größe der vorgesehenen Randstreifen.This sheet is then slit and licked using a special and special manufacturing process, in particular by punching. The contours of the slots circumscribe at least three sides of the shape of the later angled air baffles. Air baffles of this type preferably have an approximately isosceles trapezoidal contour. The size of the cover depends on the size of the edge strips provided.

Vorzugsweise in einem weiteren Arbeitsschritt findet die Abkantung der Randstreifen um entsprechende Knicklinien statt.In a further step, the edge strips are preferably folded over corresponding bending lines.

Des weiteren werden in diesem Arbeitsschritt wiederum mit einem speziell dafür hergestellten Werkzeug die Luftleitbleche hochgestellt und in einem vorher bestimmten Winkel um eine Knicklinie, welche der langen Seite eines Trapezes entspricht, abgewinkelt. Das Spezialwerkzeug für die Abwinkelung der Luftleitbleche kann so eingestellt werden, daß Deckenauslässe mit mehr oder weniger starken abgewinkelten Luftleitblechen herstellbar sind.Furthermore, in this step, the air baffles are raised again using a specially manufactured tool and angled at a predetermined angle around a crease line, which corresponds to the long side of a trapezoid. The special tool for bending the air baffles can be set so that ceiling outlets can be manufactured with more or less strong angled air baffles.

Es ist denkbar, daß im ersten Arbeitsschritt bei der Schlitzung und Stanzung der Bleche gleichzeitig auch Löcher für die Aufnahme von Befestigungselementen eingebracht werden können.It is conceivable that in the first step in the slitting and punching of the sheets, holes can also be made for receiving fastening elements.

Ein solches Verfahren zur Herstellung von Dekkenauslässen ist sehr schnell und dadurch kosten-und energiesparend. Durch den Wegfall von Schweiß- oder Klebarbeiten ist dieses verfahren auch in hohem Maße umweltschonend. Des weiteren sind Auslässe dieser Art aufgrund ihrer Bauweise pulverbeschichtbar. Gegenüber der bisherigen Sprühlackierung stellt dieses Verfahren des weiteren eine Verminderung der Umweltbelastung dar als auch eine qualitative Aufwertung eines entsprechenden Auslasses.Such a process for the production of ceiling outlets is very quick and therefore saves costs and energy. By eliminating welding or adhesive work, this process is also environmentally friendly. Furthermore, outlets of this type can be powder-coated due to their construction. Compared to the previous spray painting, this process also represents a reduction in environmental pollution and a qualitative upgrade of a corresponding outlet.

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

  • Figur 1 eine Draufsicht auf ein geschlitztes und ausgeecktes Blech, welches zu einem Deckenauslaß bearbeitet wird;
  • Figur 2 einen Querschnitt durch einen fertigen Deckenauslaß entlang Linie 11-11 gemäß Fig. 1.

  • FIG. 2 shows a cross section through a finished ceiling outlet along line 11-11 according to FIG. 1.

Figur 1 zeigt ein planes Blech R, eine Stahlplatte od. dgl., welches quadratisch ausgeformt ist. Diesem Blech sind Schlitze 1 durch Stanzungen od. dgl. eingebracht, welche die Konturen von drei Seiten von Einströmblechen 2 darstellen. Die Einströmbleche haben bevorzugt eine trapezartige Form. Die jeweils längste Seite solcher Trapeze bildet dabei jeweils eine strichpunktiert dargestellte Knicklinie 3, um welche im Anschluß an die Stanzung die Luftleitbleche 2 abgekantet werden. Für die Abkantung ist ein Spezialwerkzeug vorgesehen, welches die Luftleitbleche hochstellt und anschließend abwinkelt. Der Winkel w, in welchem die Luftleitbleche 2 gemäß Figur 2 von der planen Ebene 4 des Bleches R abragen, ist bestimmbar. Das Abkantwerkzeug ist entsprechend einstellbar.FIG. 1 shows a flat sheet metal R, a steel plate or the like, which has a square shape. Slits 1 are introduced into this sheet by punching or the like, which represent the contours of three sides of inflow sheets 2. The inflow plates preferably have a trapezoidal shape. The longest side of such trapezoids in each case forms a broken line 3 shown in dash-dotted lines, around which the air baffles 2 are bent following the punching. A special tool is provided for the bend, which raises the air baffle and then bends it. The angle w at which the air baffles 2 protrude from the plane 4 of the sheet R according to FIG. 2 can be determined. The folding tool can be adjusted accordingly.

Mit dem Einstanzen der für die Luftleitbleche bestimmten Schlitze wird das Blech R ausgeeckt. Die Größe der Ecken 6, die dabei ausgestanzt werden, entsprechen der Breite der direkt im Anschluß daran abgekanteten Seitenwände 5. Die Seitenwände 5 werden entlang von gestrichelt angedeuteten Knicklinien 7 rechtwinklig abgekantet. Löcher 8 für die Aufnahme von nicht näher dargestellten Befestigungselementen zum Festlegen des Deckenauslasses sind durch Stanzung oder Bohrung eingebracht.The sheet R is licked out by punching the slots intended for the air baffles. The size of the corners 6, which are punched out in this case, correspond to the width of the side walls 5 which are bent directly thereafter. The side walls 5 are bent at right angles along broken lines 7 indicated by dashed lines. Holes 8 for receiving fastening elements (not shown in more detail) for fixing the ceiling outlet are made by punching or drilling.
