Description

Die Erfindung betrifft eine Tür- oder Fensterfeststellvorrichtung, insbesondere einer Tür oder eines Fensters, die mit einem Antrieb versehen sind gemäß Oberbegriff des Patentanspruchs 1.The invention relates to a door or window locking device, in particular a door or a window, which are provided with a drive according to the preamble of patent claim 1.

Solche Tür- oder Fensterfeststellvorrichtungen sind bspw. aus der EP 1 662 083 A2 bekannt, bei denen mittels eines Permanentmagneten die Tür bzw. das Fenster in einer Offenstellung festgehalten wird. Bei diesen Feststellvorrichtungen wird der Elektromagnet nur bestromt, wenn die Tür bzw. das Fenster zurück in die Schließstellung bewegt werden soll. Der Elektromagnet erzeugt hierzu ein Magnetfeld, das die Wirkung des Magnetfeldes des Permanentmagneten aufhebt.Such door or window locking devices are, for example, from the EP 1 662 083 A2 known in which by means of a permanent magnet, the door or the window is held in an open position. In these locking devices, the electromagnet is energized only when the door or the window is to be moved back into the closed position. For this purpose, the electromagnet generates a magnetic field which cancels the effect of the magnetic field of the permanent magnet.

Es gibt gemäß der EP 1 662 083 A2 auch Tür- und Fensterfeststellvorrichtungen, bei denen der Elektromagnet im bestromten Zustand durch Zusammenwirken mit einer an der Tür oder dem Fenster befestigten Ankerplatte diese Tür oder dieses Fenster offenhält und erst bei einer Unterbrechung der Stromzufuhr für eine kurze Zeit die Tür oder das Fenster vom Elektromagneten freigeben wird, so dass sich die Tür oder das Fenster in eine Schließstellung bewegen kann.There are according to the EP 1 662 083 A2 also door and window locking devices in which the electromagnet in the energized state by interacting with an anchor plate attached to the door or the window holds open this door or window and release the door or window from the electromagnet only for a short time when the power supply is interrupted so that the door or window can move to a closed position.

Solche letztgenannten elektromagnetischen Feststellvorrichtungen werden häufig dazu verwendet, mit Türantrieben versehene Türflügel von Brandschutztüren offen zu halten. Dabei können Durchgänge und Flure frei begangen werden, während im Brandfall die Feststelleinrichtungen neben der Auslösung mittels eines handbetätigten Drucktasters auch automatisch über angeschlossene Rauch oder Thermoschalter ausgelöst werden können, wodurch die Türflügel durch die Türantriebe geschlossen werden. Zur Stromversorgung ist ein Netzgerät vorgesehen, das an das Gebäudenetz angeschlossen wird.Such latter electromagnetic detents are often used to keep door leaves of fire doors open. Passages and corridors can be freely negotiated, while in case of fire, the locking devices in addition to the triggering by means of a manually operated pushbutton can also be triggered automatically via connected smoke or thermal switch, whereby the door leaves are closed by the door drives. For power supply a power supply is provided, which is connected to the building network.

Es ist auch bekannt solche Türfeststeller als schleifengespeiste adressierbare magnetische Türfeststeller auszubilden, d. h. dass mehrere solcher Türfeststeller über Kommunikationsleitungen mit Strom und digitaler Information versorgt werden. Falls die Stromzufuhr und/oder die Kommunikationsverbindung unterbrochen werden, gibt der Elektromagnet nach einer kurzen Zeitdauer, die mittels eines Pufferkondensators realisiert wird, die Türe für den Schließvorgang frei.It is also known to form such door retainers as loop-fed addressable magnetic door retainers, d. H. that several such door retainers are supplied via communication lines with power and digital information. If the power supply and / or the communication connection are interrupted, the electromagnet releases the door for the closing operation after a short period of time, which is realized by means of a buffer capacitor.

Diese bekannten elektromagnetischen Feststellvorrichtungen weisen den Nachteil auf, dass diese hinsichtlich ihrer Stromversorgung entweder vom zentralen Spannungsnetz des Gebäudes oder bei einer Schleifenanbindung von einer Fernspeisequelle abhängen, um den geöffneten Zustand aufrechtzuerhalten. Somit wird bei einem nicht durch einen Brand bedingten Stromausfall, also bspw. einem technisch bedingten Stromausfall eine Brandschutztüre dennoch geschlossen. Dies trifft auch im Falle des Anschlusses solcher Feststellvorrichtungen an eine Kommunikationsleitung zu, so dass auch bei einem technisch bedingten Ausfall der Kommunikation das Schließen der Tür ebenfalls ausgelöst wird. Schließlich ist es auch unter dem Aspekt Energieeinsparung nachteilig, wenn der Elektromagnet zum Halten des geöffneten Zustands der Türe im bestromten Zustand gehalten werden muss. Eine weitere Feststellvorrichtung für eine selbstschließende Tür offenbart die DE 10 2005 013 215 A1 .These known electromagnetic locking devices have the disadvantage that they depend on their power supply either from the central voltage network of the building or in a loop connection from a remote power source to maintain the open state. Thus, a fire door is still closed in a not caused by a fire power failure, so for example. A technical power outage. This also applies in the case of the connection of such locking devices to a communication line, so that even with a technical failure of the communication, the closing of the door is also triggered. Finally, it is also disadvantageous in terms of energy saving, when the solenoid must be maintained to hold the open state of the door in the energized state. Another locking device for a self-closing door discloses the DE 10 2005 013 215 A1 ,

Der Erfindung liegt daher die Aufgabe zugrunde, eine gegenüber dem Stand der Technik verbesserte Tür- oder Fensterfeststellvorrichtung zu schaffen, die die angeführten Nachteile nicht aufweist und die eine optimale Energieeinsparung sicherstellt. Diese Aufgabe wird gelöst durch eine Feststellvorrichtung mit den Merkmalen des Patentanspruchs 1.The invention is therefore based on the object to provide a comparison with the prior art improved door or window locking device, which does not have the mentioned disadvantages and ensures optimum energy savings. This object is achieved by a locking device having the features of patent claim 1.

Es ist gemäß der Lösung der Erfindung ein Mikroschalter vorgesehen, der die Bestromung des Elektromagneten unterbricht, wenn eine Schließbewegung der Tür oder des Fensters initiiert wurde. Dies bewirkt, dass sofort nach dem die Bestromung des Elektromagneten das Abfallen der Tür oder des Fensters von der Tür- oder Fensterfeststellvorrichtung bewirkt hat, diese Bestromung unterbrochen wird. Diese Maßnahme dient in optimaler Weise der Energieeinsparung. Weiterhin ist zur Realisierung ein Abdrückbolzen vorgesehen, der in der Offenstellung der Tür oder des Fensters gegen die Federkraft eines Federelements den Mikroschalter im geschlossenen Zustand hält. Damit wird sofort nach dem der Schließvorgang der Tür oder des Fensters begonnen hat, der Abdrückbolzen unter Freigabe des Mikroschalters in seine Ausgangsposition zurück gedrückt.It is provided according to the solution of the invention, a micro-switch, which interrupts the energization of the electromagnet when a closing movement of the door or the window has been initiated. This causes immediately after the energization of the electromagnet has caused the falling of the door or the window of the door or window locking device, this energization is interrupted. This measure optimally serves to save energy. Furthermore, a Abdrückbolzen is provided for the realization that holds the microswitch in the closed state in the open position of the door or the window against the spring force of a spring element. This is immediately after the closing of the door or window has begun, the Abdrückbolzen pushed release of the microswitch to its original position.

Die Erfindung wird nachfolgend anhand einer einzigen Figur ausführlich beschrieben, die ein Aufführungsbeispiel der erfindungsgemäßen Tür- oder Fensterfeststellvorrichtung für eine Brandschutztüre in einer schematischen Darstellung zeigt.The invention will now be described in detail with reference to a single figure, which shows a performance example of the door or window locking device according to the invention for a fire door in a schematic representation.

Die Tür- oder Fensterfeststellvorrichtung 1 gemäß Figur 1 umfasst eine ringförmige, aus einem Spulenkörper und einer Wicklung hergestellte Magnetspule 10, die auf einem hohlzylindrischen Spulenkern 11 mit einer axialen Bohrung 15 aufgesteckt ist und von einem zylinderförmigen Magnetgehäuse 12 umgeben wird. Die Bestromung der Magnetspule 4 erfolgt über zwei aus dem Magnetgehäuse 12 geführte Anschlussleitungen L1 und L2.The door or window locking device 1 according to FIG. 1 comprises an annular, made of a bobbin and a coil magnetic coil 10 which is mounted on a hollow cylindrical coil core 11 with an axial bore 15 and is surrounded by a cylindrical magnet housing 12. The energization of the magnetic coil 4 via two guided from the magnet housing 12 leads L1 and L2.

Eine kreisförmige Stirnseite dieser Magnetspule 4 wird von einem wannenförmigen Deckel 13 abgeschlossen, die gegenüberliegende Stirnfläche bildet eine Polfläche 14. An den Spulenkern 11 schließt sich in Richtung des wannenförmigen Deckels 13 ein kreisringzylindrischer Permanentmagnet 3 an, der über den Spulenkern 11 und das Magnetgehäuse 12 einen Permanentmagnetkreis bildet. An einer Brandschutztüre 2 ist eine Ankerplatte 9 montiert, so dass in deren geöffneten Zustand diese Ankerplatte 9 Teil des Permanentmagnetkreises wird und daher an die Polfläche 14 gedrückt wird. Wenn somit die Brandschutztüre aus dem geschlossenen Zustand geöffnet und dabei von einer Person gegen die an einer Wand 21 befestigten Tür- oder Fensterfeststellvorrichtung 1 gedrückt wird, bleibt sie aufgrund der Haltekraft des Permanentmagneten 3 in dieser Position stehen.A circular end face of this magnetic coil 4 is completed by a trough-shaped lid 13, the opposite End face forms a pole face 14. The coil core 11 is followed in the direction of the trough-shaped lid 13, a circular cylindrical permanent magnet 3, which forms a permanent magnet circuit on the spool core 11 and the magnet housing 12. An armature plate 9 is mounted on a fire door 2, so that in the open state, this armature plate 9 becomes part of the permanent magnet circuit and is therefore pressed against the pole face 14. Thus, when the fire door is opened from the closed state while being pressed by a person against the door or window fixing device 1 fastened to a wall 21, it remains in this position due to the holding force of the permanent magnet 3.

Die axiale Bohrung 15 des Spulenkerns 11 nimmt einen Abdrückbolzen 16 auf, der mittels einer Schraubenfeder 18 in Richtung der Polfläche 14 vorgespannt wird. Hierzu weist der Abdrückbolzen 16 polseitig einen umlaufenden Flansch 20 auf, der im vorgespannten Zustand an einer Schulter der Bohrung 15 anliegt, während sich die Schraubenfeder 18 einerseits gegen diesen Flansch 20 und andererseits gegen eine mit dem Spulenkern 11 verbundene Abstützmuffe 19 abstützt. Wird die Ankerplatte 9 an die Polfläche 14 angezogen, wird gleichzeitig der Abdrückbolzen 16 in Richtung des Deckels 13 bewegt und damit auch die Federkraft auf den Abdrückbolzen 16 in Richtung der Polfläche 14 erhöht. Durch diese Bewegung des Abdrückbolzens 16 wird ein Mikroschalter 17 betätigt, der sich zwischen einer Stirnseite des Abdrückbolzens 16 und des Deckels 13 befindet, also mit dem Abdrückbolzen 16 fluchtet, d. h. genauer, dass ein Betätigungsstößel (nicht dargestellt) des Mikroschalters 17 mit dem Abdrückbolzen 16 fluchtet, so dass eine direkte Wirkverbindung zwischen dem Abdrückbolzen 16 und dem Betätigungsstößel besteht. Dabei entspricht der zur Betätigung des Mikroschalters 17 erforderliche Hub dem von dem Abdrückbolzen 16 ausführbaren Hub. Dieser Hub wird durch den Überstand, den die polflächenseitige Stirnseite des Abdrückbolzens 16 gegenüber der Polfläche 14 bildet, eingestellt. Ferner ist der Mikroschalter 17 mit durch den Deckel 13 nach außen geführten Anschlussleitungen L3 und L4 ausgestattet.The axial bore 15 of the spool core 11 receives a Abdrückbolzen 16 which is biased by a coil spring 18 in the direction of the pole face 14. For this purpose, the Abdrückbolzen 16 polseitig a circumferential flange 20 which bears against a shoulder of the bore 15 in the prestressed state, while the coil spring 18 on the one hand against this flange 20 and on the other hand against a connected to the spool 11 support sleeve 19 is supported. If the anchor plate 9 is tightened to the pole face 14, the Abdrückbolzen 16 is simultaneously moved in the direction of the lid 13 and thus increases the spring force on the Abdrückbolzen 16 in the direction of the pole face 14. By this movement of Abdrückbolzens 16, a micro-switch 17 is actuated, which is located between an end face of the Abdrückbolzens 16 and the cover 13, that is aligned with the Abdrückbolzen 16, ie more precisely, that an actuating plunger (not shown) of the microswitch 17 with the Abdrückbolzen 16th is aligned so that there is a direct operative connection between the Abdrückbolzen 16 and the actuating plunger. The required for actuation of the microswitch 17 Hub corresponds to that of the Abdrückbolzen 16 executable stroke. This stroke is set by the projection, which forms the pole-side end face of the Abdrückbolzens 16 with respect to the pole face 14. Furthermore, the microswitch 17 is equipped with connection lines L3 and L4 guided outwardly through the cover 13.

Der Mikroschalter 17 sowie die Magnetspule 4 sind entsprechend der Darstellung nach Figur 1 über ihre Anschlussleitungen L1, L2, L3 und L4 in Serie geschaltet, so dass es nun möglich ist, dass bei geschlossenem Mikroschalter 17 die Magnetspule 4 von einer angeschlossenen Batterie 5 bestromt wird, wenn wenigstens einer von zwei Schließern 6 oder 7 betätigt wird. Die beiden parallelgeschalteten Schließer 6 und 7 bilden einen Stromkreis zusammen mit der Batterie 5 und den in Serie geschalteten Magnetspule 4 und Mikroschalter 17.The micro-switch 17 and the solenoid 4 are shown in accordance with the illustration FIG. 1 Connected in series via their connecting lines L1, L2, L3 and L4, so that it is now possible that when the microswitch 17 is closed, the magnetic coil 4 is energized by a connected battery 5, if at least one of two NOs 6 or 7 is actuated. The two normally-connected normally open contacts 6 and 7 form a circuit together with the battery 5 and the series-connected magnet coil 4 and microswitch 17.

Der Schließer 6 ist funkbetätigt und wird von einem Funkempfänger 8 betätigt, also geschlossen, wenn dieser ein Betätigungssignal, bspw. im Fall eines Brandalarms erhält. Der Funkempfänger 8 wird ebenfalls von der Batterie 5 mit Betriebsspannung versorgt.The shutter 6 is radio-operated and is operated by a radio receiver 8, so closed when it receives an actuation signal, eg. In the case of a fire alarm. The radio receiver 8 is also powered by the battery 5 with operating voltage.

Aufgrund der Betätigung des Schließers 6 durch den Funkempfänger 8 wird die Magnetspule 4 bestromt, wodurch das Magnetfeld des Permanentmagneten 3 aufgehoben wird. Anstelle der Funkbetätigung ist nach Figur 1 auch eine Handbetätigung mittels des handbetätigbaren Schließers 7 möglich.Due to the operation of the shutter 6 by the radio receiver 8, the magnetic coil 4 is energized, whereby the magnetic field of the permanent magnet 3 is released. Instead of the radio control is after FIG. 1 also a manual operation by means of the manually operable closer 7 possible.

Mit der Kompensation des Permanentmagnetfeldes wird die Ankerplatte 9 aufgrund des von der Schraubenfeder 18 in Richtung der Polfläche 14 vorgespannten Abdrückbolzens 16 von der Polfläche 14 abgeworfen, so dass ein Schließvorgang der Brandschutztüre 2 initiiert wird. Das bedeutet, dass die offene Brandschutztüre 2 automatisch geschlossen wird. Da mit diesem Vorgang, also mit dem Abheben der Ankerplatte 9 auch der Abdrückbolzen 16 in seine Ausgangsposition von der Schraubenfeder 18 zurück gedrückt wird, öffnet der Mikroschalter 17, so dass dadurch der Spulenstrom der Magnetspule 4 sofort unterbrochen wird. Dies führt zu einer optimalen Energieeinsparung und damit zu einer Schonung der Batterie, so dass lange Batteriewechselintervalle gesichert sind.With the compensation of the permanent magnetic field, the anchor plate 9 is dropped due to the prestressed by the coil spring 18 in the direction of the pole face 14 Abdrückbolzens 16 of the pole face 14, so that a closing operation of the fire door 2 is initiated. That means the open Fire door 2 is closed automatically. Since with this process, so with the lifting of the anchor plate 9 and the Abdrückbolzen 16 is pushed back into its original position by the coil spring 18, the micro switch 17 opens, thereby the coil current of the solenoid 4 is interrupted immediately. This leads to an optimal energy saving and thus to a protection of the battery, so that long battery replacement intervals are secured.

Mit dem Öffnen des Mikroschalters 17 ist der Permanentmagnetkreis des Permanentmagneten 3 wieder aktiv, so dass bei erneutem Öffnen der Brandschutztür 2 diese wieder in diesem geöffneten Zustand gehalten werden kann, bis ein weiteres Alarmsignal eine Betätigung des Schließers 6 durch den Funkempfänger 8 bewirkt.With the opening of the microswitch 17, the permanent magnet circuit of the permanent magnet 3 is active again, so that when reopening the fire door 2, this can be kept in this open state again, until another alarm signal causes actuation of the shutter 6 by the radio receiver 8.

Jedoch ist es auch möglich, den Schließer 6 so lange durch den Funkempfänger 8 geschlossen zu halten, bis eine Rückstellung des Alarms erfolgt, so dass dadurch der Schließer 6 wieder in seinen Ruhezustand, also in den offenen Zustand wechselt. Damit wird während des Alarmzustandes sichergestellt, dass die Brandschutztür 2 nicht im geöffneten Zustand gehalten wird. Denn eine Öffnung der Brandschutztür während dieses Alarmzustandes würde wieder zu einem Schließen des Mikroschalters 17 führen, mit der Folge einer Bestromung der Magnetspule 4 und damit einer Kompensation des Permanentmagnetfeldes des Permanentmagneten 3.However, it is also possible to keep the shutter 6 closed by the radio receiver 8 until a reset of the alarm takes place, so that thereby the shutter 6 again changes to its idle state, ie to the open state. This ensures during the alarm condition that the fire door 2 is not kept in the open state. For an opening of the fire door during this alarm condition would again lead to a closing of the microswitch 17, with the result of energization of the magnetic coil 4 and thus a compensation of the permanent magnetic field of the permanent magnet. 3

Um eine sichere Stromversorgung der erfindungsgemäßen Tür- oder Fensterfeststellvorrichtung 1 sicherzustellen, ist für die Batterie 5 eine Batteriewechselanzeige vorgesehen, die optisch und/oder akustisch einen erforderlichen Batteriewechsel anzeigt. Auch ist es möglich, einen erforderlichen Batteriewechsel per Funk zu melden bzw. in einer Brandschutzzentrale anzuzeigen, wenn der Funkempfänger zusätzlich auch einen Funksender aufweist, bspw. als Transceiver ausgebildet ist.In order to ensure a secure power supply of the door or window locking device 1 according to the invention, a battery replacement indicator is provided for the battery 5, which visually and / or acoustically indicates a required battery replacement. It is also possible to change the battery Report by radio or display in a fire protection center, if the radio receiver additionally also has a radio transmitter, for example. Is designed as a transceiver.
