Description

Wetterlutte Gegenstand des Hauptpatents ist eine faltbare Wetterlutte, bei der aus Kunststoffolien durch Verschweißung von Folienrändern hergestellte Luttenschläuche zur Bildung und Aufrechterhaltung eines glatten Strömungsquerschnittes auf ihrer Außenhaut aufgeschweißte Durchmesserhalter tragen, die aus in Abständen angeordneten Ringen oder zusammenschiebbaren, über Luttenlänge sich streckenden Spiralschrauben bestehen.Weather flute The subject of the main patent is a foldable weather flute, in the case of duct hoses made from plastic films by welding the edges of the film to create and maintain a smooth flow cross-section on their Outer skin wear welded diameter holders, which are arranged at intervals Rings or collapsible spiral screws stretching over the length of the duct exist.

Die Erfindung besteht darin, an den Schlauchenden Versteifungsringe vorzusehen, die gleichzeitig als Durchmesserhalter dienen. Die Versteifungsringe an den Schlauchenden werden zweckmäßig mit den Schlauchenden umwickelt und durch Anwendung von Wärme in diese eingeschweißt. Außerdem ist es vorteilhaft, die Endversteifungsringe mit Aufhängevorrichtungen zu versehen.The invention consists in stiffening rings at the hose ends to be provided, which also serve as diameter holders. The stiffening rings at the hose ends are expediently wrapped with the hose ends and through Application of heat welded into this. It is also beneficial to use the end stiffening rings to be provided with hanging devices.

Die durch die Erfindung erreichten Vorteile sind darin zu sehen, daß die an den Enden von Luttenschüssen angeordneten Durchmesserhalter gleichzeitig als Kupplungsringe verwendbar sind und an den Luttenkupplungsstellen der Durchmesser im Wetterluttenstrang beibehalten wird, wodurch Wirbelungen an den Kupplungsstellen vermieden werden; dabei dient die dünne Schlauchwand als Dichtungsmittel, weil bei der Einwicklung der Endversteifungsringe die dünnwandigen Kunststoffschlauchwände nach außen zu liegen kommen und somit beim Auseinanderkuppeln von Luttenschüssen zwei Schlauchwände von Luttenkörpern das Abdichten der Schüsse an den Luttenenden bewirken. Dadurch, daß die Versteifungsringe außerdem noch Aufhänger für die Lutten tragen, wird der dünne L uttenkörper selbst nicht mit Tragkräften belastet, so daß die Lutte nach der Erfindung aufgehängt werden kam., ohne daß Gewichtsbelastungen den dünnwandigen Luttenkörper beanspruchen.The advantages achieved by the invention can be seen in the fact that the diameter holders arranged at the ends of pipe sections simultaneously can be used as coupling rings and the diameter at the duct coupling points is retained in the Wetterluttenstrang, creating eddies at the coupling points be avoided; the thin tube wall serves as a sealant because at the wrapping of the end stiffening rings the thin-walled plastic tube walls come to lie on the outside and thus when disconnecting pipe sections two tube walls of duct bodies sealing the shots at the duct ends. Because the stiffening rings also have hangers for the ducts, the thin duct body itself does not have the load-bearing capacity loaded, so that the duct according to the invention came to be hung. Without weight loads claim the thin-walled duct body.
