Vorwerk & Co. Wuppertal. den 05. November 1981Vorwerk & Co. Wuppertal. November 05, 1981 Interholding GmbH.Interholding GmbH. Rückschlagklappe für FilterstutzenNon-return valve for filter port

Die Neuerung bezieht sich auf eine Rückschlagklappe aus elastischem Material wie Gummi o.a., für den aufrechtstehenden Filterstutzen von Staubsaugern, insbesondere Handstaubsaugern, wobei die Rückschlagklappe auf dem Filterstutzen befestigt ist.The innovation relates to a non-return valve made of elastic material like rubber or similar, for the upright filter socket of vacuum cleaners, especially handheld vacuum cleaners, with the non-return valve open is attached to the filter socket.

Es existieren Rückschlagklappen, die aus gestanzten Gummiplatten besteig hen. Diese sind einseitig am Filterstutzen befestigt. Sie haben jedoch :f den Nachteil, daß sie bei schwerem Schmutz ineinanderknicken und dadurch ■ in den Filterstutzen gedrückt werden. Die Funktion des Abdichtens ist dadurch nicht gewährleistet.There are check valves that are made of stamped rubber sheets. These are attached to one side of the filter socket. However, they have : f the disadvantage that they bend into each other when there is heavy dirt and are thus ■ pressed into the filter socket. The function of the seal is not guaranteed.

Weiterhin sind Rückschlagklappen bekannt, welche direkt am Saugstutzen angespritzt sind. Sie bestehen äuis Kunststoff, wie z.B. Polyäthylen o.a. Sie sind zwar gegen Einknicken geschützt, haben jedoch den Nachteil, in ihrem Drehpunkt sehr starr zu sein. D.h., sie schließen sich nie vollständig, so daß auch hier eine Abdichtung nicht gewährleistet ist.Furthermore, check valves are known, which are located directly on the suction nozzle are molded on. They are made of plastic, such as polyethylene or similar. Although they are protected against buckling, they have the disadvantage of being very rigid in their pivot point. That is, they never close completely, so that a seal is not guaranteed here either.

Aufgabe der Neuerung ist es nun, eine Rückschlagklappe zu erstellen, die so formstabil ist, daß sie durch schweren Schmutz nicht eingeknickt wird und die in ihrem Drehpunkt so elastisch ist, daß sie immer gut schließt und somit gut abdichtet.The task of the innovation is now to create a non-return valve that is so dimensionally stable that it is not buckled by heavy dirt and which is so elastic in its pivot point that it always closes well and thus seals well.

Neuerungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs gelöst.According to the innovation, the object is achieved by the features of the claim.

Somit hat die Neuerung zum entscheidenden Vorteil, daß auf einfache Art und Weise eine Rückschlagklappe geschaffen wird, welche zum einen so stabil ist, daß sie durch schweren Schmutz nicht eingeknickt werden kannThus, the innovation has the decisive advantage that in a simple way and way a non-return valve is created, which on the one hand is so stable is that it cannot be buckled by heavy dirt

und zum anderen im Drehpunkt so elastisch ist, daß sie den Filterstutzen immer gut abdichtet.and on the other hand, the pivot point is so elastic that it touches the filter socket always seals well.

Nachstehend ist ein Ausführungsbeispiel der Neuerung gezeichnet und beschrieben. An embodiment of the innovation is drawn and described below.

Es zeigt:It shows:

Fig. 1 Einen Filterstutzen mit Rückschlagklappe im Schnitt,Fig. 1 A filter socket with a non-return valve in section, Fig. 2 die Draufsicht auf eine Rückschlagklappe nach Fig. 1FIG. 2 shows the plan view of a non-return valve according to FIG. 1

Der Filterstutzen 6 nach Fig. 1 läßt bei Saugbetrieb in Pfeil richtung strömende staubbeladene Luft durch, die dann von einem Staubfilterbeutel 7, der auf dem Filterstutzen 6 angeordnet ist, aufgefangen wird.
Am Filterstutzen 6 ist nun eine Rückschlagklappe 1 angeordnet, welche verhindern soll, daß im Staubfilterbeutel 7 vorhandener Staub wieder herausfällt. Die Rückschlagklappe 1 ist an einem Halter 8 am Filterstutzen 6 mittels der Öffnung 9 eingehakt. Beim Saugen nimmt sie dabei die in unterbrochenen Linien gezeichnete Stellung ein. Dabei sorgt das Filmscharnier 2 für einen elastischen Drehpunkt. Wird nicht mehr gesaugt, so legt sich die Rückschlagklappe 1 in die in ausgezogenen Linien gezeichnete Stellung und bietet hier durch die umlaufende Wulst 5 genügend Knicksicherheit, so daß sie nicht in den Filterstutzen 6 hinein gedrückt werden kann. Die Wulst 5 ist deshalb umlaufend, damit zum einen genügend Knicksicherheit vorhanden ist, die Rückschlagklappe 1 jedoch nicht so schwer wird, daß die Luft sie nicht mehr anheben kann.
The filter socket 6 according to FIG. 1 allows dust-laden air flowing in the direction of the arrow during suction operation, which air is then collected by a dust filter bag 7 which is arranged on the filter socket 6.
A non-return flap 1 is now arranged on the filter socket 6, which is intended to prevent any dust present in the dust filter bag 7 from falling out again. The non-return flap 1 is hooked into a holder 8 on the filter socket 6 by means of the opening 9. When sucking, it assumes the position shown in broken lines. The film hinge 2 provides an elastic pivot point. If the suction is stopped, the non-return flap 1 moves into the position shown in solid lines and, thanks to the circumferential bead 5, offers sufficient security against kinking so that it cannot be pressed into the filter socket 6. The bead 5 is therefore circumferential so that, on the one hand, there is sufficient security against kinking, but the non-return valve 1 is not so heavy that the air can no longer lift it.

Fig. 2 zeigt noch einmal die Rückschlagklappe 1 als Draufsicht.
Das Filmschamier 2 teilt sie in die Teile 3 und 4 auf. Im Teil 3 ist die „ öffnung 9 zur Befestigung angeordnet und das Teil 4 weist die Wulst 5 \ zur Versteifung auf.
Fig. 2 shows once again the non-return valve 1 as a plan view.
The film hinge 2 divides them into parts 3 and 4. In Part 3, the "opening 9 is arranged for mounting and the part 4, the bead 5 \ stiffening on.
