Description

Die Erfindung betrifft eine Verriegelungsvorrichtung für Notausgangstüren mit einer wand- oder rahmenseitig befestigbaren elektromagnetisch wirkenden Verriegelungseinheit und einer türseitig befestigbaren ferromagnetischen Ankerplatte. Derartige Verriegelungsvorrichtungen sind durch die Dokumente FR-A-2 624 184, FR-A-2 582 040 und US-A-3 971 581 bekannt.The invention relates to a locking device for emergency exit doors with a wall or frame side attachable electromagnetic acting Locking unit and a door-mounted ferromagnetic Anchor plate. Such locking devices are by the Documents FR-A-2 624 184, FR-A-2 582 040 and US-A-3 971 581 are known.

Bei Notsituationen in öffentlichen Gebäuden und Räumen muss gewährleistet sein, dass Personen das Gebäude oder den Raum sofort durch in den Flucht- und Rettungswegen befindlichen Türen verlassen können. Diese Türen sind während des normalen Betriebes über eine Verriegelungsvorrichtung verschlossen. Die Freischaltung der Notausgangstüren in Fluchtwegrichtung erfolgt von einer Zentrale oder durch einen zu betätigenden Not-Auf-Taster mit gleichzeitiger Alarmmeldung und -signalisierung.In emergency situations in public buildings and rooms must be guaranteed be that people immediately move through the building or the room leave the doors located escape and rescue routes. These doors are during normal operation via a locking device locked. The activation of the emergency exit doors in escape direction is done by a central or by a to be operated Emergency button with simultaneous alarm message and signalisation.

Eine Verriegelungsvorrichtung für Notausgangstüren ist durch die GB 2 085 956 A bekannt geworden. Bei der vorbekannten Notausgangstür findet rahmenseitig ein elektrisch erregbarer Flächenmagnet Verwendung, der mit einer ferromagnetischen Platte an der Tür zusammenwirkt. Die Verwendung eines derartigen Flächenmagneten erfordert eine großbauende Einheit, die die ohnehin nachteilige aufbauende Anordnung im Türbereich unnötig vergrößert. Der Nachteil dieser bekannten Lösung besteht des weiteren darin, dass eine Anpassung an unterschiedliche Haltekräfte nur durch den vollständigen Austausch des Flächenmagneten realisierbar ist. Dies bedeutet auch, dass eine entsprechende Anzahl unterschiedlich dimensionierter Flächenmagneten gefertigt und bevorratet werden muss.A locking device for emergency exit doors is through GB 2 085 956 A became known. In the known emergency exit door finds frame-side an electrically excitable area magnet use, which cooperates with a ferromagnetic plate on the door. The Use of such a surface magnet requires a großbauende Unit that the already detrimental constructive arrangement in the door area unnecessarily enlarged.

This also means that a corresponding number will be different dimensioned surface magnet manufactured and stored must become.

In der DE 37 16 021 C2 ist eine vergleichsweise kleinbauende Verriegelungseinrichtung beschrieben. Dabei findet ein türseitiger Schließhalter Verwendung, in den ein Fallenschenkel eines rahmenseitigen Hebelsystems eingreift, welches von einem Elektromagneten betätigt wird. Der bei geschlossener Tür bestromte und angezogene Elektromagnet gibt den Schließhalter aufgrund einer in das Hebelsystem eingeschalteten Druckfeder bei Stromausfall frei. Nachteilig ist hierbei die Verwendung des aufwendigen Hebelsystems.In DE 37 16 021 C2 is a comparatively small-sized locking device described. There is a door-side lock holder Use, in which a trailing leg of a frame-side lever system engages which is actuated by an electromagnet. Of the energized and energized when the door is closed gives the Locking holder due to a spring inserted in the lever system in case of power failure free.

Gelöst wird diese Aufgabe mit den im Patentanspruch 1 angegebenen Merkmalen. Vorteilhafte Ausgestaltungen des Gegenstandes des Patentanspruches 1 sind in den Unteransprüchen angegeben.This problem is solved by the features specified in patent claim 1 Features. Advantageous embodiments of the subject of the claim 1 are given in the subclaims.

Die erfindungsgemäße Verriegelungsvorrichtung gemäß dem Patentanspruch 1 weist den Vorteil auf, dass durch die Verwendung von mehreren einzelnen variabel anordbaren und/oder variabel verschaltbaren Spulen für eine Verriegelungseinheit eine Anpassung an unterschiedliche technische Rahmenbedingungen, wie beispielsweise unterschiedliche Haltekräfte, unterschiedliche Türabmessungen und -gewichte und verschiedene Betriebsspannungen, mit geringem Aufwand möglich ist. Einerseits durch die Anzahl und Dimensionierung der einzelnen Spulen und andererseits durch das Schaltungskonzept. Schaltungstechnisch sind dabei Reihenschaltungen, Parallelschaltungen und gruppenweises Zusammenschalten von Spulen möglich.The locking device according to the invention according to the claim 1 has the advantage that through the use of several individual variably arranged and / or variably interconnected coils for a locking unit an adaptation to different technical Conditions, such as different holding forces, different door dimensions and weights and different Operating voltages, with little effort is possible. On the one hand by the number and dimensions of the individual coils and on the other hand through the circuit concept. Circuit technology are here Series connections, parallel connections and group-wise interconnection possible from coils.

Die vorteilhafte Anordnung ermöglicht im Reparaturfall oder bei sonstigen Erfordernissen den einfachen Austausch einzelner Spulen. Die Spulen sind vorzugsweise rund ausgebildet, dass heißt eine Wicklung ist in fertigungstechnisch einfacher Weise um einen zylindrischen Spulenkern gewickelt. Der einheitliche Aufbau der Spulen ermöglicht eine kostengünstige Fertigung und Lagerhaltung.The advantageous arrangement allows for repair or other Require easy replacement of individual coils. The spools are preferably round, that is, a winding is in manufacturing technology simply wrapped around a cylindrical bobbin. The uniform structure of the coils allows a cost-effective Production and storage.

Eine einheitlich ausgestaltete und damit kostengünstige Basiseinheit in Form eines Magnetmodules erfüllt die Grundfunktionen, dass heißt hierbei sind die Steckplätze für die Spulen und die entsprechenden elektrischen Schaltungsstrukturen vorbereitet. Des weiteren ermöglicht das kompakte und platzsparende Magnetmodul eine optisch vorteilhafte kompakte Gehäuseform. Insbesondere gegenüber dem Stand der Technik erfolgt bei gleicher Haltekraft eine Verkleinerung der Verriegelungsvorrichtung. Vorteilhafterweise sind die Spulen nebeneinander in einer Reihe in Längserstreckung der Verriegelungseinheit in einem massiven, vorzugsweise metallenen und/oder metallisch beschichteten, Block angeordnet.A uniformly designed and thus inexpensive base unit in Form of a magnetic module fulfills the basic functions, that means here are the slots for the coils and the corresponding electrical ones Circuit structures prepared.

Das Magnetmodul ist von einer Dichtung umgeben, die als Schutz des Gehäuseinneren vor Spritzwasser dient. Eine Montageplatte zur Befestigung der Ankerplatte ist unter Zwischenlage einer Futterplatte an einer Tür befestigbar, so dass damit Toleranzen ausgeglichen werden können. Die Ankerplatte ist vorzugsweise kardanisch an der Montageplatte gelagert und mittels eines Bolzens mit Spiel positioniert. Diese Art der Befestigung der Ankerplatte erlaubt eine begrenzte Bewegung der Ankerplatte, so dass hierdurch eine möglichst flächige Anlage der Ankerplatte am Magnetmodul ermöglicht wird und die magnetische Haltekraft optimal übertragen werden kann. Ein hohl ausgebildeter Spulenkern in mindestens einer der Spulen ermöglicht die Anordnung eines verschiebbar gelagerten Stiftes, der nach Abschaltung der Stromversorgung sicherstellt, dass die Flächenhaftung aufgrund des Restmagnetismus zwischen dem Magnetmodul und der Ankerplatte zuverlässig und unverzüglich aufgehoben wird. Dies ist erforderlich, damit die Fluchttür im Notfall sofort freigeschaltet ist.The magnetic module is surrounded by a seal that serves as protection of the Housing interior before splash water is used. A mounting plate for attachment the anchor plate is with the interposition of a lining plate on a Door attachable, so that tolerances can be compensated. The anchor plate is preferably gimbal mounted on the mounting plate and positioned by means of a bolt with play. This type of attachment the anchor plate allows limited movement of the anchor plate, so that thereby a possible flat contact the anchor plate is enabled on the magnetic module and the magnetic holding power optimal can be transferred. A hollow formed coil core in at least one of the coils allows the arrangement of a slidably mounted Pen, which ensures after switching off the power supply, that the surface adhesion due to the residual magnetism between the Magnet module and the anchor plate reliably and immediately lifted becomes. This is required so that the escape door immediately unlocked in an emergency is.
