Abstract

The door (100) has a door frame (20) and door panel (10) held on the frame by one or more electromagnetic holding magnets (40) which switch off automatically in the event of a fire. A door closer device (30) is fixed on the door panel and is connected to a fixing point (34) of the door frame by a closer arm (32) whereby torque lifting the door panel off from the frame acts on the closer arm. The door panel is preferably mounted on the outside of the building to overlap the drop side of the door frame.

Description

Die Erfindung betrifft eine Fluchtwegtür.The invention relates to an escape route door.

Es sind Fluchtwegtüren bekannt, die insbesondere in eine Außenwand eines Gebäudes oder eines Lagerraums eingesetzt sind und ein- oder zweiflügelig ausgebildet sind. Diese Türen öffnen bevorzugt nach außen und sind durch Schloss- oder Riegelmechanismen geschützt. Im Brandfall ist das Schloss oder der Riegel nach Überwindung von Sicherungen zu öffnen. Beispielsweise ist der Schlüssel neben der Tür in einem Kasten eingehängt, deren Glasscheibe eingeschlagen werden kann.Escape route doors are known which in particular in an outer wall of a building or a storage room are used and have one or two wings are. These doors open preferentially outward and are through lock or Locking mechanisms protected. In the event of a fire, the lock or bolt is after being overcome of fuses to open. For example, the key is next to the door hung in a box, whose glass pane can be broken.

Nachteilig hieran ist, dass bei einer Flucht aus dem Gebäude, möglicherweise bei bereits stark verrauchten Fluchtwegen, der Riegel- oder Schlossmechanismus erst gefunden und betätigt werden muss.The disadvantage of this is that with a Escape from the building, possibly in the case of already heavily smoked escape routes, the bolt or lock mechanism only found and activated must become.

Nachteilig ist weiterhin, dass die bekannte Fluchtwegtür nicht automatisch durch eine Brandmeldeanlage geöffnet werden kann, um frische Luft in das Gebäudes zu leiten und so einen Rauchabzug zu bewirken.Another disadvantage is that the well-known escape route door can not be opened automatically by a fire alarm system to get fresh Air into the building to conduct and so to smoke evacuation.

Es stellt sich daher die Aufgabe, eine Fluchtwegtür so zu gestalten, dass die Tür im normalen Betrieb verschlossen bleibt und auch nicht durch Unbefugte geöffnet werden kann, dass aber im Brandfall eine leichte Öffnung durch die fliehenden Personen und/oder durch die Brandmeldeanlage bewirkt werden kann.It is therefore the task an emergency exit door to shape the door remains closed during normal operation and also not by unauthorized persons open can be, but in the event of fire, an easy opening through the fleeing people and / or caused by the fire alarm system can be.

Diese Aufgabe wird durch eine Fluchtwegtür mit den Merkmalen des Anspruchs 1 gelöst.This task is through an escape route door with the Features of claim 1 solved.

Die mit der Erfindung erzielten Vorteile liegen insbesondere darin, dass ein einfaches Öffnen im Brandfall möglich ist, um die Flucht von Personen zu erleichtern und Frischluft ins Gebäude zu leiten. Eine kostengünstige Fertigung ist möglich, da weitgehend auf handelsübliche Komponenten zurückgegriffen werden kann. So sind die Haltemagnete bereits bei Brandabschnittstüren im Inneren von Gebäuden bekannt.The advantages achieved with the invention are in particular that it is easy to open in the event of a fire, to make it easier for people to escape and to bring fresh air into the building. An inexpensive Manufacturing is possible since largely on commercial Components can be used can. The holding magnets are already inside the fire compartment doors of buildings known.

Es kann weiterhin eine handelsübliche Obertür- oder Bodenschließvorrichtung verwendet werden. Durch die erfindungsgemäße Anordnung des Gehäuses der Türschließvorrichtung an dem Türblatt und des Schließerarms an der Türzarge wird die ursprüngliche Funktion der Türschließvorrichtung umgekehrt und erfindungsgemäß für eine Vorspannung des Türblatts benutzt, so dass dieses nach Freigabe durch die Haltemagnete automatisch zur Gebäudeaußenseite hin öffnet und Frischluft einströmt.It can still be a standard top door or Floor locking device be used. Due to the inventive arrangement of the housing Door locking device on the door leaf and of the closer arm on the door frame becomes the original Function of the door locking device vice versa and according to the invention for a bias of door panel used, so this automatically after release by the holding magnets to the outside of the building opens and fresh air flows in.

Vorzugsweise sind drei übereinander angeordnete Haltemagnete an einer Fallenseite der Türzarge angeordnet. Durch etwa gleich über die Höhe verteilte Haltemagnete wird erreicht, dass die Tür im normalen Betrieb dicht geschlossen ist.Three are preferably one above the other arranged holding magnets arranged on a latch side of the door frame. By about right over distributed the height Holding magnets is achieved that the door is tight in normal operation closed is.

Insbesondere werden Haltemagnete mit einer Kraft von 800 N eingesetzt. Eine solche Haltekraft ist ausreichend, um ein unbefugtes Öffnen im Normalbetrieb zu verhindern. Im Brandfall können aber ein bis zwei Personen die Tür durch ihr Körpergewicht öffnen.In particular, are holding magnets used with a force of 800 N. Such a holding force is sufficient to prevent unauthorized opening to prevent in normal operation. In the event of a fire, however, one or two people can the door open by their body weight.

Vorteilhaft ist auch, wenn die erfindungsgemäße Fluchtwegtür in eine Einbruchmeldeanlage eingebunden ist. Dies kann beispielsweise durch die Überwachung des Stroms der Haltemagneten erfolgen. Bei einem unbefugten Öffnen der Tür im Normalbetrieb wird dann ein Signal erzeugt und ein Alarm ausgelöst.It is also advantageous if the escape route door according to the invention is in a Intrusion alarm system is integrated. This can be done, for example, by The supervision of the current of the holding magnets. In the event of unauthorized opening of the Door in In normal operation, a signal is then generated and an alarm is triggered.

Die Erfindung wird nachfolgend mit Bezug auf die Zeichnungen näher erläutert. Es zeigen im Einzelnen:The invention is described below Reference to the drawings in more detail explained. They show in detail:

2 die erfindungsgemäße in Fluchtwegtür in Schnittansicht von oben. 2 the escape route door according to the invention in a sectional view from above.

1A zeigt eine Fluchtwegtür 100 mit einem Türblatt 10, das in einer Türzarge 20 an einer Bandseite 21 aufgehängt ist. Die Fluchtwegtür 10 überlappt vorzugsweise an einer Fallenseite 22 mit der Türzarge 20, wobei im Bereich der Überlappung drei Haltemagnete 40 angeordnet sind, die das Türblatt gegen eine nicht dargestellte Dichtung in die Zarge drücken. 1A shows an escape route door 100 with a door leaf 10 that in a door frame 20 on a hinge side 21 is hung. The escape route door 10 preferably overlaps on one trap side 22 with the door frame 20 , with three holding magnets in the area of the overlap 40 are arranged, which press the door leaf against a seal, not shown, in the frame.

An dem Türblatt 10 ist eine Türschließvorrichtung 30 mit ihrem Gehäuse angeordnet, die als an sich bekannter Bodenschließer oder als Obertürschließer ausgebildet sein kann und die über ihren Schließerarm 32 mit einem Befestigungs punkt 34 der Türzarge 20 verbunden ist. Auf den Schließerarm 32 wirkt eine Vorspannung, die insbesondere durch an sich bekannte Federelemente, auch Gasdruckfedern, in der Türschließvorrichtung 30 hervorgerufen wird. Während diese Vorspannung bei normalen Türen mit einer an der Türzarge befestigten Türschließvorrichtung zu einem Schließen des Türblatts führt, führt die erfindungsgemäß vorgesehene umgekehrte Anordnung der Türschließvorrichtung 30 zu einem öffnenden Moment, mit dem das Türblatt 10 von der Zarge 20 weggedrückt wird.On the door leaf 10 is a door locking device 30 arranged with its housing, which can be designed as a conventional floor closer or as an upper door closer and via its closer arm 32 with an attachment point 34 the door frame 20 connected is. On the closer arm 32 acts a bias, in particular by spring elements known per se, also gas pressure springs, in the door closing device 30 is caused. While this pretensioning in normal doors with a door closing device fastened to the door frame leads to a closing of the door leaf, the reverse arrangement of the door closing device provided according to the invention leads to the closing 30 at an opening moment with which the door leaf 10 from the frame 20 is pushed away.

Die Haltemagnete 40 werden mit einem permanenten Haltestrom beaufschlagt. Im Brandfall werden die Haltemagnete 40 entweder stromlos geschaltet oder fallen bei Zerstörung der elektrischen Anlage selbsttätig ab. Das Türblatt 10 wird nicht mehr an der Zarge gehalten und öffnet durch die Federkraft nach außen.The holding magnets 40 are subjected to a permanent holding current. In the event of a fire, the holding magnets 40 either switched off or fall off automatically if the electrical system is destroyed. The door leaf 10 is no longer held on the frame and opens outwards due to the spring force.

Es kann zusätzlich ein Paniktaster 42 vorgesehen sein, mit dem der Haltestrom für die Haltemagnete 40 manuell unterbrochen werden kann. Mit der herbeigeführten manuellen Unterbrechung wird ein Signal erzeugt, das einer Einbruchmeldeanlage den Öffnungszustand der Tür signalisiert.An additional panic button can be used 42 be provided with which the holding current for the holding magnets 40 can be interrupted manually. With the manual interruption that is brought about, a signal is generated which signals the opening status of the door to an intrusion detection system.

Das Türblatt besteht vorzugsweise aus Eisenwerkstoffen, so dass die Haltemagnete das Türblatt direkt halten können und eine erhöhte Brandbeständigkeit gegeben ist. Bei anderen Werkstoffen sind im Wirkbereich der Haltemagnete magnetisierbare Platten in das Türblatt eingesetzt.The door leaf is preferably made of ferrous materials, so that the holding magnets can hold the door leaf directly and there is increased fire resistance. With other materials magnetizable plates are inserted into the door leaf in the effective range of the holding magnets.
