Description

Bezeichnung: Klappe für Rohrpostanlagen Die Erfindung betrifft eine Klappe fUr Rohrpostanlagen, deren Aufbau einfach mit geringem Kostenaufwand und trotzdem funktionssicher ist. Klappen dieser Art sind wahlweise für Druckluft- und Saugluftbetrieb einsetzbar, In der Rohrposttechnik sind Klappen verschiedenster Bauart bekannt. Ihre Aufgabe besteht unter anderern darin, Rohrquerschnitte pneumatisch dicht zu verschließen, wie z.B.Designation: flap for pneumatic tube systems The invention relates to a Flap for pneumatic tube systems, the structure of which is simple and inexpensive is still functionally reliable. Flaps of this type are optionally available for compressed air and Suction air operation can be used, in pneumatic tube technology there are various flaps Design known. Their task is, among other things, to create pipe cross-sections pneumatically to close tightly, e.g.

Ausfahrklappen und Zwischenklappen.Extension flaps and intermediate flaps.

Diese Klappen werden entweder mit handelsüblichen Scharnieren versehen, oder es werden Gelenke aus verschiedenartigen Einzelteilen zwischen den beweglichen und festen Klappenteil gesetzt.These flaps are either fitted with standard hinges, or there are joints of various individual parts between the movable ones and fixed flap part set.

Durch Federn werden die Klappen in Ruhe- bzw. Arbeitsstellung gehalten.The flaps are held in the rest or working position by springs.

Gelenke dieser Art sind nicht ganz wartungsfrei, sie müssen in entsprechenden Zeitabständen überprüft werden. Durch die Anzahl der Einzelteile sind wolche Klappen relativ aufwendig.Joints of this type are not entirely maintenance-free; they have to be appropriately Be checked at intervals. Due to the number of individual parts, there are some flaps relatively complex.

Die Erfindung zeigt eine einfache Klappe, die' diese Nachteile beseitigt. Sie besteht aus einem einzigen Teil. Wie bei den z.B. an Photo-Apparaten bekannten und angewandten Filmscharnieren wurde erfindungsgem§ß die Klappe mit einem solchen Scharnier versehen.The invention shows a simple flap which eliminates these disadvantages. It consists of a single part. As is the case with the ones known, for example, from photo apparatus and applied film hinges, according to the invention, the flap was made with such Provided with a hinge.

Unter Filmscharnier versteht man eine in das Material (vorwiegend Kunststoff, z.B. Polypropylen) eingearbeitete Soll-Knick-Stelle, die eine hohe Lebensdauer gegen Biegewechsel und im allgemeinen auch eine Rückstellkraft in eine vorgegebene Ruhestellung besitzt.A film hinge is one in the material (predominantly Plastic, e.g. polypropylene) incorporated predetermined kink point, which has a long service life against alternating bending and in general also a restoring force in a predetermined one Owns rest position.

Klappen dir Bauart sind völlig wartungsfrei, einfach herzustellen, funktionssicher und ausreichend dauerfest.The flaps are completely maintenance-free, easy to manufacture, functionally reliable and sufficiently durable.

Im folgenden wird ein Ausführungsbeispiel beschrieben, und zwar zeigt die Figur 1 eine Klappe mit Filmscharnier als Gelenk an einem Rohrstück angebracht, Figur 2 ein Klappenteil mit Filmscharnier, Figur 3 eine Klappe mit angebrachtem Filmscharnier.In the following an embodiment is described, namely shows FIG. 1 shows a flap with a film hinge attached to a piece of pipe as a joint, FIG. 2 a flap part with a film hinge, FIG. 3 a flap with an attached Film hinge.

Das Rohrstück 1 ist in Figur 1 mit der Klappe 2 geschlossen.The pipe section 1 is closed with the flap 2 in FIG.

Durch die Elastizität des Materials (z.I3. Kunststoff} liegt der bewegliche Teil der Klappe 2 an der zu verschließenden Rohröffnung an. Der Anpressdruck bzw. Vorspannkraft der Klappe wird durch die in Figur 2 dargestellte Einschnürung 5 bestiltunt. Mit dieser Einschnürung 5 wird auBerdem die Abknickstelle der Klappe 2 vorbestimmt.Due to the elasticity of the material (e.g. I3. Plastic) the movable Part of the flap 2 on the pipe opening to be closed. The contact pressure or The pretensioning force of the flap is determined by the constriction 5 shown in FIG. With this constriction 5, the kink point of the flap 2 is also predetermined.

Uber eine Defestigungsplatte 3 und eine handelstibliche Rohrschelle 4 wird in Verbindung mit der Klappe 2 auf einfachste Art der pneumatisch dichte Verschluß eines Rohrstückes 1 erreicht.Via a fastening plate 3 and a standard pipe clamp 4 is pneumatically sealed in the simplest way in connection with the flap 2 Closure of a pipe section 1 is achieved.

Wenn nach Figur 3 als Klappe 7 ein Material benutzt wird, das nicht direkt zum Filmscharnier verarbeitet werden soll, wie z.B.If, according to FIG. 3, a material is used as the flap 7 that does not is to be processed directly into the film hinge, e.g.

Filz odcr Leder, dann kann das Filmscharnier 6 als getrenntes Bauteil z.B. mit der Schelle 4 und der Klappe 7 mit der Offen-Stellung 8 durch Nieten oder auf andere Weise verbunden werden.Felt or leather, the film hinge 6 can then be used as a separate component e.g. with the clamp 4 and the flap 7 with the open position 8 by riveting or connected in other ways.
