Abstract

The emergency door opener has 2 mechanically or electrically coupled door locking elements released automatically in response to a fire alarm signal, the loss of the current supply or operation of a manual setting element under control of a spring bias and a respective toggle lever mechanism. The spring bias is normally equalised by a as electromagnet coupled to the electrical supply network. The spring system is incorporated in the door frame and is supplied via electric leads embedded in the wall, to prevent tempering. ADVANTAGE - Rapid opening of emergency exit door with manual override.

Description

ProblemstellungProblem

1. Paniktüren in Krankenhäusern, Diskotheken, Versammlungsstätten und Großbauten jeglicher Art sollen in der Regel im Normalfall verschlossen sein, andererseits aber, im Feuer- oder Panikfall, sollen solche Türen ohne Anstrengung von innen her durch die bedrohten Menschen zu überwinden sein und von außen durch die herannahenden Rettungsmannschaften.1. Panic doors in hospitals, discotheques, meeting places and large buildings of any kind should normally be closed, but on the other hand, in the event of fire or panic, such doors should pass through without effort from the inside the threatened people must be overcome and from the outside by the approaching ones Rescue teams.

2. Feuerwehren und andere Rettungsdienste fordern, daß Paniktüren von außen her zu öffnen sein müssen, wenn2. Fire departments and other emergency services require panic doors to be closed from the outside must be open when

  • - das Sicherheitsstromnetz ausfällt (immer ein Indiz dafür, daß ein Sicherheitsproblem besteht);- the safety power grid fails (always an indication that a safety problem consists);
  • - die Brandmeldezentrale des betreffenden Gebäudes einen automatischen Brandalarm auslöst;- The fire alarm center of the building in question has an automatic fire alarm triggers;
  • - ein allgemeiner Feueralarm an dem betreffenden Standort per Hand ausgelöst wird.- a general fire alarm is triggered by hand at the location in question becomes.

3. Gebäudebetreiber fordern, daß Außentüren mittels eines besonderen Tasters von Hand in die Position "entriegelt" gebracht werden können, um bestimmten Personen den Zutritt zu ermöglichen.3. Building operators require that external doors by means of a special button Hand in the "unlocked" position can be placed to certain people to allow access.

4. Gebäudebetreiber fordern, daß Türen (z. B. Geschäftstüren) während einer längeren Zeit entriegelt bleiben, wobei die Steuerung von Hand oder nach Zeitprogramm durch ein Leitsystem oder ein anderes Steuerungssystem möglich sein muß.4. Building operators require that doors (such as shop doors) remain open for a longer period of time Time remains unlocked, whereby the control by hand or by time program a control system or another control system must be possible.

Zur Verdeutlichung der gesamten Problematik seien noch einmal zwei in Außentüren anzutreffende Schließsysteme erläutert:To clarify the entire problem, two more are to be found in the outer doors Locking systems explained:

Normaltüren
Türen mit einem normalen Schloß sind beispielsweise in Privatwohnungen anzutreffen. Verfügt eine solche Tür auf beiden Seiten über einen Handgriff (also keinen Knauf), so kann man die Tür frei überwinden, wenn sie nicht abgeschlossen ist.
Normal doors
Doors with a normal lock can be found in private homes, for example. If such a door has a handle on both sides (i.e. no knob), the door can be freely overcome if it is not locked.

Eine abgeschlossene Tür kann man dagegen nicht überwinden. Sollte eine solche Tür auch die Funktion einer Paniktür übernehmen, so war es lange Zeit gültige Praxis, den Schlüssel in einen roten Schlüsselkasten mit Glasscheibe auf der Gebäudeinnenseite in unmittelbarer Türnähe anzuordnen. Diese Art der Problemlösung ist aber nicht mehr erlaubt, da die Schlüssel oft entwendet wurden und den Menschen im Katastrophenfall der Fluchtweg abgeschnitten war.A locked door, on the other hand, cannot be overcome. Should be such a door also act as a panic door, so it was a long-standing practice put the key in a red key box with a glass pane on the inside of the building to be arranged in the immediate vicinity of the door. However, this type of problem solving is no longer allowed because the keys were often stolen and people in the In the event of a disaster the escape route was cut off.

Panikschloß
Die Industrie hat daraufhin ein Panikschloß entwickelt, bei dem sowohl der Handgriff wie auch die durch den Schlüssel betätigte Wechselfalle den Schließriegel betätigt, der in einer mechanischen Folgesteuerung die Schloßfalle freigibt. Der innen angebrachte Handgriff wird dabei ergänzend als über die gesamte Türbreite angeordnet Stange ausgeführt, die es selbst kleinen Kindern, die sich an die Stange hängen, ermöglicht, die Tür im Katastrophenfall zu öffnen. Von außen ist eine solche Tür nur mittels des zugehörigen Schlüssels zu öffnen. Weiterhin versagt ein normaler Türöffner, da jedesmal, wenn die Tür ins Schloß fällt, auch der Schließriegel automatisch ins Schloß fällt. (Ein üblicher Türöffner wirkt nur auf die Türfalle und versagt bei zugeschlossener Tür seinen Dienst, was durchaus für Normaltüren erwünscht sein kann.)
Panic lock
The industry then developed a panic lock in which both the handle and the change latch operated by the key actuate the locking bolt, which releases the lock latch in a mechanical sequence control. The handle on the inside is also designed as a bar across the entire width of the door, which enables even small children hanging on the bar to open the door in the event of a disaster. Such a door can only be opened from the outside using the associated key. Furthermore, a normal door opener fails, because every time the door falls into the lock, the locking bolt also automatically falls into the lock. (A normal door opener only affects the latch and fails when the door is closed, which can be desirable for normal doors.)

Erfindunginvention

Der von mir erfundene automatische Türöffner ist ein in den feststehenden Türrahmen mit einer gegen Fremdeinwirkung von außen fest verlegten Unterputzverdrahtung versehener Doppeltüröffner mit zwei Schließblechen, die durch zwei getrennte, aber durch den gemeinsamen Anker eines Ruhestrommagneten gekoppelte Kniehebelsysteme von einer an dem Anker angreifenden Zugfeder bei Stromunterbrechung in die Offenposition gezogen werden, so daß jede nicht abgeschlossene Tür, aber auch jede mittels Schlüssel abgeschlossene Tür, von innen durch in Bedrängnis geratene Personen, aber auch von außen durch am Gebäude ankommende Rettungsmannschaften, problemlos überwunden werden kann. Die Stromunterbrechung erfolgt bei einer als Paniktür deklarierten Tür in fünffacher Weise:The automatic door opener I invented is one in the fixed door frame flush-mounted wiring that is permanently installed against external influences Double door opener with two striking plates, separated by two but by the common Anchor of a quiescent current magnet coupled toggle lever systems from one to the The tension spring attacking the anchor is pulled into the open position in the event of a power failure. so that every door that is not locked, but also every door locked with a key Door, from inside by people who are in trouble, but also from outside by on Rescue teams arriving in buildings can be easily overcome. The Power is interrupted five times for a door declared as a panic door:

  • - durch Ausfall des speisenden Netzes;- due to failure of the supply network;
  • - durch Unterbrechung von der Brandmeldezentrale aus im Alarmfall;- by an interruption from the fire alarm control panel in the event of an alarm;
  • - durch Unterbrechung von Gebäudeleitsystem aus;- by interrupting the building management system;
  • - durch Handunterbrechung mittels Taster (kurzzeitig) oder Schalter (nach Zeitprogramm);- by manual interruption using a button (briefly) or a switch (according to the time program);
  • - durch den eingebauten Kontakt, solange die Tür geöffnet ist.- through the built-in contact as long as the door is open.

Der zuletzt genannte Türkontakt verhindert, daß die Schiebebleche vorzeitig in die Schließposition fallen und ein endgültiges Schließen der durch einen Türschließer zufallenden Tür unmöglich machen.The last-mentioned door contact prevents the sliding plates from moving into the closed position prematurely fall and a final closing of the door closing by a door closer to make impossible.

Ein weiterer Kontakt an dem gleichen Türmikroschalter kann als potentialfreier Kontakt mit dem Gebäudeleitsystem verbunden werden und sorgt dort für die Meldung "Tür xy steht offen". Statt der in der Skizze angenommenen Schiebebleche wären auch Drehkolben oder andere Verriegelungssysteme denkbar und statt der mechanischen Schalter können auch Lichtschranken oder Näherungsschalter eingesetzt werden. Der von mir erfundene Doppeltürschließer kann insbesondere auch jede normale Tür mit einfachem Schloß zu einer Paniktür aufwerten, die verhindert, daß es im Katastrophenfall zu menschlichen Tragödien kommt, weil eine Außentür nicht geöffnet werden kann. Natürlich müssen solche Türsysteme regelmäßig überprüft werden. Diesen Dienst könnte am besten der Schornsteinfeger als zusätzliche Aufgabe mit übernehmen, der ja regelmäßig in alle Häuser kommt. Der Türkontakt bewirkt im übrigen bei jedem Öffnen einer so ausgerüsteten Tür eine Bewegung.Another contact on the same door microswitch can be used as a potential-free contact be connected to the building management system and provides the message "Door xy is open ". Instead of the sliding plates assumed in the sketch, there would also be rotary pistons or other locking systems conceivable and instead of mechanical switches light barriers or proximity switches can also be used. The one I invented Double door closers can also be any normal door with a simple lock Upgrade the panic door, which prevents human tragedies in the event of a disaster comes because an outer door cannot be opened. Of course, such door systems must be checked regularly. This service could best be done by the chimney sweep take on as an additional task that comes regularly to all houses. The Door contact also causes a movement each time a door equipped in this way is opened.
