Abstract

Louvre has blades which are made of extruded plastic. They have a thickened root with a hole through it into which the hinge pins fit. The main part of the blade projects from the root in a shallow curve bowed outwards. This ensures that in the closed position there is only line contact between successive blades. The blades are held on short nylon pins which fit in to the holes in the roots. The other end of each pin fits into a recess in the side of the frame which is reinforced at this point. The blade shape, mounting arrangement and material all reduce noise caused by chatter of the blades when the fan runs at slow speed.

KLIMATECHNIK WEISS, 405 Mönchengladbach- Krahnendonk 127 "selbsttätige Vollkunststoff-Ventilator-Verschlußklappe"KLIMATECHNIK WEISS, 405 Mönchengladbach- Krahnendonk 127 "automatic all-plastic ventilator shutter"

BESCHREIBUNGDESCRIPTION

Die Erfindung betrifft eine selbsttätige Vollkunststoff-Ventilator- Verschlußklappe (kurz Klappe genannt), welche vor einen Ventilator installiert wird, um diesen vor Regen, Schnee, Staub/ und sonstigen Witterungseinflüssen zu schützen.The invention relates to an automatic all-plastic fan Closure flap (called flap for short), which is installed in front of a fan to protect it from rain, To protect snow, dust / and other weather influences.

Es ist bekannt, zur Erfüllung dieser Erfordernisse Klappen vor einen Ventilator zu installieren, welche sich öffnen wenn der Ventilator sich dreht (bzw. die Flügelräder) und sich schließen, wenn der Ventilator steht(bzw. die Flügelräder).It is known to install flaps in front of a fan to meet these requirements, which flaps open when the fan turns (or the impellers) and close when the fan stops (or the Impellers).

Es machte sich beim Einsatz dieser Klappen bemerkbar, daß die Lamellen, welche meistens aus Metall waren, verrosten, verrotten oder sich durch Windstöße verbogen haben und dann herausfielen. Ebenfalls zeigte sich in der Praxis, daß die Lamellen bei bestimmten Strömungsgeschwindigkeiten flatterten,z.B. beim Einsatz.-vor einem, drehzahl gesteuerten Ventilator.It was noticeable when using these flaps that the lamellas, which were mostly made of metal, rust, rot or have been bent by gusts of wind and then fell out. It was also shown in practice that that the lamellae fluttered at certain flow velocities, e.g. when using.-in front of a speed-controlled Fan.

Die Aufgabe wurde erfindermäßig gelöst, in dem die Klappen, der Rahmen sowie die Lamellen, aus säurebeständigem Kunststoff hergestellt sind, und die Lamellen in eine bestimmte Form, durch ein Extrödierverfahren, gebracht wurden, daß sie "einen Anschlag haben", also nicht mehr flattern können. Außerdem wird als Aufhängeachse für die Lamelle ein Nylonstift gewählt, welcher die Reibungsverhältnisse sehr stark verringert.(Zur Offenbarung dieses Vorganges dienen die beigefügten Aktenzeichnungen).The object was achieved according to the invention, in which the flaps, the frame and the slats, made of acid-resistant Are made of plastic, and the lamellas have been brought into a certain shape using an extrusion process, that they "have a stop", so no longer flutter can. In addition, a nylon pin is chosen as the suspension axis for the slat, which greatly reduces the friction conditions greatly reduced. (Serve to reveal this process the attached file drawings).

Die mit der Erfindung erzielten Vorteile bestehen darin, daß die Wirkleistung (Luftleistung) des Ventilators sich stark erhöht, daß die Lebensdauer der Klappe praktisch unbegrenzt ist, und die Lebensdauer des Ventilators erheblich vergrößert.Auch das "Flattergeräusch11 ist nicht mehr vorhanden. Weitere Vorteile sind mit der Aufhängevorrichtung der Lamellen verbunden, sie ermöglicht es, die einzelnen Lamellen herauszunehmen und in Seifenwasser zu reinigen. Dieses ist gegebenenfalls notwendig, wenn eine Klappe vor einen Ventilator installiert ist, welcher Küchenluft, Gaststättenluft, Imbisstubenluft US.W. absaugt, welche bekanntlich s^tark verschmutzt ist. Man biegt die lamellen mit der Hand leicht an, nimmt sie mit der Hand einzeln heraus, und reinigt diese. Anschließend setzt man sie wieder in den Rahmen ein.Weitere Vorteile* Ebenfalls wird der Luftstrom der aus der Klappe tritt, konstant in eine Richtung gelenkt-rechtwinkelig zur Ilappenvorderseite- und die anliegenden Flächen, Hauswände usw. nicht durch Staub, Rußsteilchen sowie Fettpartikelchen welche sich im Luftstrom befinden, verschmutzt.The advantages achieved with the invention are that the effective power (air output) of the fan is greatly increased, that the service life of the flap is practically unlimited, and the service life of the fan is increased considerably. Also the "fluttering noise 11 is no longer present. Further advantages are connected to the suspension device of the slats, it enables the individual slats to be removed and cleaned in soapy water It is very dirty. You bend the slats slightly with your hand, take them out one by one, and clean them. Then you put them back into the frame , constantly steered in one direction - at right angles to the anterior side of the lobe - and the adjacent surfaces, Hausw ands etc. are not contaminated by dust, soot particles and grease particles that are in the air flow.

Selbsttätige Vollkunststoff-Ventilator-Verschlußklappe mitspeziell extrodierter Lamelle,welche sich nur um 90° (Altgrad) bzw. 1009 (Neugrad) öffnen kann. Weiterhin soll die Aufhängung der Lamelle unter Schutz gestellt werden, sie ist dadurch gekennzeichnet, daß der aus Polystyrol gespritzte Rahmen, an der für die Aufhängung der Lamelle vorgesehenen Stelle, dreifach verstärkt wurde; die Aufhängung selber besteht aus einem Nylonstift (oder Einsteckbolzen), welcher zur einen Seite im Rahmen ruht, und zur anderen Seite in ein vorgebohrtes Loch in der Lamelle ruht.Automatic all-plastic ventilator flap with specially extruded lamella, which can only open by 90 ° (degrees) or 1009 (degrees). Furthermore, the suspension of the lamella is to be placed under protection, it is characterized in that the frame, which is injection-molded from polystyrene, has been reinforced three times at the point provided for the suspension of the lamella; the suspension itself consists of a nylon pin (or plug-in bolt), which rests on one side in the frame and on the other side in a pre-drilled hole in the slat. 709827/0395709827/0395
