Description
Die vorliegende Erfindung betrifft einen Streifenbelüfter gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a strip aerator according to the preamble of
Die
Mit der in der
Aufgabe der vorliegenden Erfindung ist es, einen gattungsgemäßen Streifenbelüfter zur Verfügung zu stellen, der die gleichen Vorteile aufweist, insbesondere aber eine besonders dichte Befestigung der Membran an der Tragplatte gewährleistet.Object of the present invention is to provide a generic strip aerator available, which has the same advantages, but in particular ensures a particularly tight attachment of the membrane to the support plate.
Diese Aufgabe wird erfindungsgemäß mit einem Streifenbelüfter gelöst, der die Merkmale des Anspruchs 1 aufweist.This object is achieved with a strip aerator having the features of
Erfindungsgemäß haben sowohl das Klemmprofil als auch die Nut jeweils einen V-förmigen Querschnitt mit von einem Scheitel divergierenden Schenkeln. Dabei sind die Schenkel des Klemmprofils aus einem entspannten Zustand gegeneinander einfederbar, wobei sie in entspanntem Zustand einen größeren Winkel zwischen sich einschließen als die Schenkel der Nut. Zum Festlegen der Membran in der Nut wird der Randbereich der Membran in die Nut eingelegt und anschließend das Klemmprofil in die Nut eingedrückt. Dazu werden die Schenkel des Klemmprofils beim Eindrücken in die Nut unter Verringerung des zwischen ihnen eingeschlossenen Winkels gehen aneinander zusammengedrückt, was das Einführen des Klemmprofils in die Nut erleichtert. Nachdem das Klemmprofil vollständig in der Nut aufgenommen ist, entspannen sich deren Schenkel wieder. Sie drücken dadurch gegen die Schenkel der Nut, wodurch die Membran zwischen den Schenkeln der Nut und des Klemmprofils eingeklemmt wird. Die Klemmkraft hängt dabei von dem Winkel ab, den die Schenkel des Klemmprofils im entspannten Zustand zwischen sich einschließen und dem Winkel, den die Schenkel im entspannten Zustand zwischen sich einschließen. Der Hinterschnitt der Nut verhindert, dass das Klemmprofil aus der Nut herausgedrückt werden kann.According to the invention, both the clamping profile and the groove each have a V-shaped cross-section with legs diverging from a vertex. The legs of the clamping profile from a relaxed state against each other einfederbar, wherein they include a relaxed angle a larger angle between them than the legs of the groove. To set the membrane in the groove, the edge region of the membrane is inserted into the groove and then pressed the clamping profile in the groove. For this purpose, the legs of the clamping profile when pressing into the groove with reduction of the angle enclosed between them are pressed together, which facilitates the insertion of the clamping profile in the groove. After the clamping profile is completely absorbed in the groove, relax their legs again. They thereby press against the legs of the groove, whereby the membrane between the legs of the groove and the clamping profile is clamped. The clamping force depends on the angle from which enclose the legs of the clamping profile between them in the relaxed state and the angle between which enclose the legs in the relaxed state between them. The undercut of the groove prevents the clamping profile can be pushed out of the groove.
In weiterer Ausgestaltung der Erfindung kann das Klemmprofil ein Vollprofil aus elastischem Kunststoff sein, in dessen dem Scheitel gegenüberliegender Basis eine längsverlaufende Nut vorgesehen ist. Die Nut erleichtert das Einfedern der Schenkel des Klemmprofils.In a further embodiment of the invention, the clamping profile may be a solid profile made of elastic plastic, in which the apex of the opposite base a longitudinal groove is provided. The groove facilitates the compression of the legs of the clamping profile.
In einer weiteren Ausführungsform der Erfindung kann das Klemmprofil ein offenes Profil aus Federstahl sein.In a further embodiment of the invention, the clamping profile may be an open profile made of spring steel.
In allen Fällen wird ein sicherer und dichter Halt der Membran an den Längsrändern der Tragplatte auch bei hohen Beanspruchungen erreicht.In all cases, a secure and tight grip of the membrane is achieved at the longitudinal edges of the support plate, even at high loads.
Die Erfindung wird nachstehend anhand von Ausführungsbeispielen näher erläutert. In der dazu gehörigen Zeichnung zeigt:The invention will be explained in more detail below with reference to embodiments. In the accompanying drawing shows:
