Description

Die Erfindung bezieht sich auf eine gasdichte Türe, deren Flügel mit einer aufblasbaren Dichtung ausgestattet sind, die gegen eine Zarge wirkt.The invention relates to a gas-tight door, the wing with an inflatable seal that works against a frame.

Derartige gasdichte Türen haben sich als einflügelige Türen, bei denen die Zarge abgerundete Ecken aufweist (Siehe CH-A-291 128), bereits vielfach bewährt, weil sie eine hohe Funktionssicherheit aufweisen. Die Herstellung von zweiflügeligen Türen ist jedoch bisher nicht in befriedigender Weise gelungen, insbesondere deshalb, weil keine einfache und sichere Abdichtung auch der Anschlußkanten der beiden Flügel gefunden wurde. Wird zwischen die beiden Flügel ein vertikaler Holm eingesetzt und mit der Zarge verbunden, muß dieser Holm beim Öffnen der Tür jedesmal entfernt werden, um einen freien Durchgang zu erreichenSuch gas-tight doors have proven to be single-leaf doors where the frame has rounded corners (see CH-A-291 128), already tried and tested many times because it is a have high functional reliability. The production of two-winged However, doors have so far not been satisfactorily successful, in particular this is because there is no simple and secure sealing of the connecting edges either of the two wings was found. Will be between the two wings vertical spar inserted and connected to the frame, this spar every time you open the door to be cleared to give a clear passage to reach

Die Erfindung hat es sich daher zum Ziel gesetzt, eine zweiflügelige gasdichte Türe zu schaffen, die einfach zu bedienen ist und bei der eine sichere Abdichtung gewährleistet ist.The invention therefore has set itself the goal of a two-winged to create gas-tight doors that are easy to use and with one secure sealing is guaranteed.

Erreicht wird dies dadurch, daß die beiden Flügel der zweiflügelig ausgebildeten Tür wenigstens in ihrem zueinander weisenden Bereich abgerundete Ecken aufweisen, daß der Stehflügel mit einer mit der Zarge zusammenwirkenden Verriegelung versehen ist, und daß auf einem der Flügel Füllteile verschiebbar gelagert sind, die die beiden, in Vorderansicht annähernd dreieckförmigen Räume zwischen den abgerundeten Ecken der beiden Flügel und dem oberen sowie unteren waagrechten Zargenholm ausfüllen, wobei durch die aufblasbaren Dichtungen der Flügel die Füllteile gegen die Zargenholme gedrückt werden.This is achieved in that the two wings of the two wings trained door at least in their mutually facing area have rounded corners that the standing wing with a with the frame cooperating lock is provided, and that on one of the wings Filling parts are slidably mounted, the two, in front view approximately triangular spaces between the rounded corners of the two sashes and the upper and lower horizontal frame spars fill in, with the inflatable seals of the wing filling parts be pressed against the side rails.

Bei einer erfindungsgemäß ausgebildeten Türe kann nach Entspannung der aufblasbaren Dichtung, Öffnen des Gehflügels und Öffnen der Verriegelung des Stehflügels die Türe wie bei einer normalen zweiflügeligen Türe geöffnet werden. Dabei werden die Füllstücke mitbewegt und so ein freier Durchgang geschaffen. With a door designed according to the invention, relaxation can take place the inflatable seal, opening the active wing and opening the Locking the standing wing the door like a normal two-wing Door to be opened. The filler pieces are moved with it and so free passage created.

Bei einer zweckmäßigen Ausführungsform der Erfindung sind die Füllstücke auf dem oberen und dem unteren, in die Zargenholme eingreifenden Riegeln der Verriegelung verschiebbar gelagert.In an expedient embodiment of the invention, the Filling pieces on the top and bottom, in the frame bars engaging latches of the lock are slidably mounted.

Die elektrische Steuerung erfolgt bei einer erfindungsgemäßen Türe vorteilhaft derart, daß das die Zuführung von Luft zu den aufblasbaren Dichtungen steuernde Ventil in einem Stromkreis liegt, der von der Verriegelung des Stehflügels und der Schließung des Gehflügels abhängige Schließkontakte aufweist.The electrical control takes place in a door according to the invention advantageously such that the supply of air to the inflatable Valve that controls the seals lies in a circuit that is separated from the Locking of the standing wing and the closing of the active wing dependent Has closing contacts.

Wenigstens ein Teil dieser Schließkontakte ist bei einer bevorzugten Ausführungsform der Erfindung als Reed-Kontakte ausgebildet.At least part of these make contacts is in a preferred one Embodiment of the invention designed as reed contacts.

Um dem Benutzer die entsprechenden Stellungen der Tür anzuzeigen, ist ein Stromkreis angeordnet, der von der Verriegelung des Stehflügels abhängige Schließkontakte und eine Anzeigevorrichtung enthält.To show the user the appropriate door positions, is a circuit arranged by the locking of the standing wing dependent closing contacts and a display device contains.

Eine besonders kompakte Ausführung wird erreicht, wenn die elektrischen und pneumatischen Steuereinrichtungen in verschließbaren Ausnehmungen der Türflügel angeordnet sind und die Zu- und Ableitung von elektrischer und pneumatischer Energie sowie Steuerungsimpulsen über Verbindungsschläuche zur Zarge erfolgt.A particularly compact design is achieved if the electrical and pneumatic control devices in lockable Recesses of the door panels are arranged and the supply and discharge of electrical and pneumatic energy as well as control impulses via Connection hoses to the frame are made.

Nachstehend ist die Erfindung anhand eines in den Zeichnungen dargestellten Ausführungsbeispieles näher beschrieben, ohne auf dieses Ausführungsbeispiel beschränkt zu sein. Dabei zeigen: Fig. 1 eine Ansicht einer erfindungsgemäßen Türe; Fig. 2 in vergrößertem Maßstab eine Ansicht im Bereich des oberen Füllteiles; Fig. 3 eine Ansicht in Richtung des Pfeiles III in Fig. 2; Fig.4 einen Schnitt entlang der Linie IV - IV in Fig. 1; Fig. 5 das Prinzipschaltbild des elektrischen Stromkreises einer Tür nach der Erfindung.The invention is based on one in the drawings illustrated embodiment described in more detail without this Embodiment to be limited. 1 shows a view a door according to the invention; Fig. 2 is an enlarged view in the area of the upper filler; Fig. 3 is a view in the direction of the arrow III in Fig. 2; 4 shows a section along the line IV - IV in Fig. 1; Fig. 5 the schematic diagram of the electrical circuit of a door according to the Invention.

Gemäß Fig. 1 weist eine Türe zwei Flügel 1 und 2 auf, wobei der Flügel 1 der Stehflügel, der Flügel 2 der Gehflügel ist. Die beiden Flügel 1 und 2 sind in einer Zarge 3 gelagert, deren Ecken abgerundet sind. Auch die Ecken der beiden Flügel 1 und 2 sind abgerundet. Rund um jeden Flügel 1 bzw. 2 verläuft eine aufblasbare Dichtung 4. 1, a door has two wings 1 and 2, the Wing 1 is the standing wing, wing 2 is the active wing. The two wings 1 and 2 are mounted in a frame 3, the corners of which are rounded. Also the Corners of the two wings 1 and 2 are rounded. Around each wing 1 or 2 an inflatable seal 4.

Der Stehflügel 1 ist mit einer Anschlagleiste 5 verbunden, in der Riegel 6 verschiebbar gelagert sind. Bei Betätigung durch einen Handgriff 7 können die Riegel 6 in und außer Eingriff mit dem oberen bzw. unteren Holm der Zarge 3 gebracht werden. An den Riegeln 6 sind Füllteile 8 über einen Lagerring 9 mit Befestigungsplatte verschiebbar gelagert (Fig. 2 und 3). Die Füllteile 8 füllen die beiden, in Vorderansicht annähernd dreieckförmigen Räume zwischen den abgerundeten Ecken der beiden Flügel 1, 2 und dem oberen sowie unteren Holm der Zarge 3 aus. Um die Füllteile 8 bei Öffnen des Stehflügels 1 zu diesem hin zu bewegen, sind an den Riegeln 6 Stellringe 10 angeordnet.The standing wing 1 is connected to a stop bar 5, in the latch 6 are slidably mounted. When operated by a handle 7 can the latch 6 in and out of engagement with the upper or lower spar of Frame 3 are brought. On the bars 6 are 8 filler parts over a Bearing ring 9 with mounting plate slidably mounted (Fig. 2 and 3). The Filling parts 8 fill the two, approximately triangular in front view Spaces between the rounded corners of the two wings 1, 2 and upper and lower spar of the frame 3. Around the filling parts 8 when opening of the standing wing 1 to move towards this are 6 adjusting rings on the bolts 10 arranged.

In den Zeichnungen ist der obere Riegel 6 mit den zugehörigen Lagerteilen für den oberen Füllteil 8 dargestellt. Der untere Riegel 6, der Füllteil 8 usw. ist jedoch völlig gleich ausgebildet, so daß sich eine gesonderte Darstellung erübrigen dürfte.In the drawings, the upper latch 6 is associated with the Bearing parts shown for the upper filler 8. The lower latch 6, the Filler 8, etc. is, however, completely identical, so that there is a separate presentation is likely to be superfluous.

Die Füllteile 8 sind beim gezeigten Ausführungsbeispiel an ihren Seitenflächen, insbesondere an den der Zarge 3 zugewendeten Seitenflächen, mit einer Dichtung 11 versehen.The filling parts 8 are at their in the embodiment shown Side surfaces, in particular on the side surfaces facing the frame 3, provided with a seal 11.

In verschließbaren Ausnehmungen 12 der Flügel 1 und 2 sind die elektrischen und pneumatischen Steuerungsteile für die Betätigung der Türe untergebracht. Dieser Steuerung gehören Reed-Kontake 20 und 21 sowie ein Riegelkontakt 22 an, wobei die Kontakte 20 und 22 in Abhängigkeit von der Verriegelung des Stehflügels 1 betätigt werden. Energie- und Steuerleitungen sind in Verbindungsschläuchen 13 zwischen den Flügeln 1 und 2 sowie der Zarge 3 untergebracht. Eine Verriegelungsanzeige 23, eine Funktionsanzeige 24R, 24G und ein Betätigungsknopf für einen Schalter 25 sind in einem Paneel im Gehflügel 2 angeordnet.In closable recesses 12 of the wings 1 and 2 are the electrical and pneumatic control parts for the operation of the door housed. This control includes reed contacts 20 and 21 as well Bolt contact 22, the contacts 20 and 22 depending on the Locking the standing wing 1 can be operated. Power and control lines are in connecting tubes 13 between the wings 1 and 2 and the Frame 3 housed. A lock indicator 23, a function indicator 24R, 24G and an operating button for a switch 25 are in one Panel arranged in the active leaf 2.

Anhand der Fig. 5, die das Prinzipschaltbild einer erfindungsgemäßen Tür wiedergibt, wird nun die Wirkungsweise dieser Tür erläutert.5, which is the basic circuit diagram of an inventive Reproduces door, the operation of this door will now be explained.

Die Steuerung wird über eine Niederspannungsquelle 26, z.B. mit 24 Volt gespeist. Wird der Stehflügel 1 geschlossen und verriegelt, fließt Strom über den Reed-Kontakt 20 und den Riegelkontakt 22 zur Verriegelungsanzeige 23, wodurch die ordungsgemäße Verriegelung des Stehflügels 1 angezeigt wird. In der Funktionsanzeige leuchtet eine rote Lampe 24R.The control is via a low voltage source 26, e.g. at 24 Volt powered. If the standing wing 1 is closed and locked, current flows via the reed contact 20 and the bolt contact 22 for Lock indicator 23, whereby the proper locking of the Standing wing 1 is displayed. A red light illuminates in the function display 24R lamp.

Wird auch der Gehflügel 2 geschlossen, schließt der Reed-Kontakt 21 und nach Schließen des Schalters 25, wobei der damit verbundene Schalter 25' geöffnet wird, kann Strom zu einem Luftschalter 27 fließen, der die Zufuhr von Druckluft zu den aufblasbaren Dichtungen 4 freigibt. Die grüne Lampe 24G der Funktionsanzeige kann aber erst aufleuchten, bis nach Erreichen des erforderlichen Druckes ein Druckschalter 28 die Stromzufuhr freigibt.If the active leaf 2 is also closed, the reed contact 21 closes and after closing switch 25, the switch associated therewith 25 'is opened, current can flow to an air switch 27, which the Supply of compressed air to the inflatable seals 4 releases. The green Lamp 24G of the function display can only light up until after When the required pressure is reached, a pressure switch 28 supplies power releases.

Durch die Ausdehnung der aufblasbaren Dichtung 4 werden die Füllteile 8 gegen die Holme der Zarge 3 gedrückt und es wird auch dieser Bereich gasdicht.Due to the expansion of the inflatable seal 4 Filling parts 8 pressed against the bars of the frame 3 and it will be this Area gastight.

Soll der Gehflügel 2 geöffnet werden, wird der Schalter 25 geöffnet, der Schalter 25' gleichzeitig geschlossen, wodurch die grüne Lampe 24G erlischt und die rote Lampe 24R aufleuchtet. Der Luftschalter 27 gibt nun ein Auslaßventil frei und die Luft kann aus den Dichtungen 4 entweichen. Die Füllteile 8 werden nicht mehr an die Zarge gepreßt und die Tür kann geöffnet werden.If the active leaf 2 is to be opened, the switch 25 is opened, the switch 25 'is closed simultaneously, causing the green lamp 24G goes out and the red lamp 24R lights up. The air switch 27 now enters Exhaust valve free and the air can escape from the seals 4. The Filling parts 8 are no longer pressed against the frame and the door can be opened become.

Die Betätigung des Schalters 25 bzw des Luftschalters 27 kann beim Schließen des Gehflügels 2 durch diesen selbsttätig erfolgen. Es ist aber auch möglich, den Schalter 25 als Handschalter auszubilden, wobei bei einer Ausführung der Handschalter in Serie mit einem vom Gehflügel betätigten Schalter liegen kann, sodaß eine wirkungsvolle Betätigung des Handschalters nur nach den, Schließen des Gehflügels 2 möglich ist.The actuation of the switch 25 or the air switch 27 can Closing of the active leaf 2 takes place automatically. It is also possible to design the switch 25 as a manual switch, with one Hand switches in series with one operated by the active leaf Switch can lie, so that an effective actuation of the hand switch only after closing the active leaf 2 is possible.

Überhaupt sind im Rahmen der Erfindung zahlreiche Abänderungen denkbar. So müssen die Füllteile 8 nicht an den Riegeln 6 verschiebbar gelagert sein. Es ist auch möglich, die Füllteile 8 unabhängig von den Riegeln 6 am Stehflügel 1 oder auch am Gehflügel 2 verschiebbar zu lagern.In general, numerous changes are within the scope of the invention conceivable. So the filling parts 8 do not have to be moved on the bars 6 be stored. It is also possible to fill the parts 8 independently of the bars 6 slidably on the standing wing 1 or on the active wing 2.

Es ist auch nicht erforderlich, daß alle vier Ecken der Flügel bzw. die Ecken der Zarge abgerundet sind. An den Außenkanten der Flügel könnte je ein flexibler Abdichtungsstreifen, der einerseits am Flügel, anderseits an der Zarge befestigt ist, die Abdichtung übernehmen. Die aufblasbare Dichtung bräuchte dann nur an drei Seiten jedes Flügels angeordnet werden.It is also not necessary that all four corners of the wing or the Corners of the frame are rounded. On the outer edges of the wings could ever a flexible sealing strip that on the one hand on the wing, on the other hand on the Frame is fastened, take over the sealing. The inflatable seal would then only need to be arranged on three sides of each wing.
