Description

Die Erfindung betrifft eine elektromagnetische Türverriegelung zum Verriegeln einer Tür insbesondere einer Schiebetür in einer ihrer Endstellungen.The invention relates to an electromagnetic door lock for locking a door, in particular a sliding door in one of its end positions.

Es sind Feststellanlagen für Feuerschutzabschlüsse bekannt, mit denen eine Ausweitung von Bränden in Gebäuden gestoppt und die Ausbreitung von Brandrauch und -gasen auf benachbarte Räume oder Gebäude verhindert wird. Diese Anlagen bestehen im wesentlichen aus einem Brandmelder, einem Rauchschutzschalter und einem Haft- bzw. Elektromagnet, mit dem eine Feuerschutztür in ihrer geöffneten Stellung gehalten wird. Der Rauchschutzschalter steuert den entsprechenden Haftmagneten in der Weise, daß bei Empfang von Signalen eines Brandmelders die Haltekraft des Haftmagneten zusammenbricht und die Tür dann durch einen automatischen Türschließer geschlossen wird.Locking systems for fire barriers are known, with which the spread of fires in buildings is stopped and the spread of fire smoke and gases is prevented to neighboring rooms or buildings. These systems essentially consist of a fire detector, a smoke protection switch and an adhesive or electromagnet with which a fire protection door in your is held in the open position. The smoke protection switch controls the corresponding holding magnet in such a way that when signals from a fire alarm are received, the holding force of the holding magnet breaks down and the door is then closed by an automatic door closer.

Weiterhin sind verschiedene Duschabtrennungen bekannt, deren Türelemente im geschlossenen Zustand durch Permanentmagnete verriegelt werden oder bei denen durch den Einsatz solcher Magnete eine selbsttägige Ausrichtung von Verschlußleisten und somit eine Abdichtung erzielt wird.Furthermore, various shower partitions are known, the door elements of which are locked by permanent magnets in the closed state, or in which the use of such magnets results in an automatic alignment of closure strips and thus a seal.

Schließlich sind Schiebetüranlagen bekannt, bei denen an den Türflanken und an den Türzargen Magnete in der Weise angebracht sind, daß ihre gleichnamigen Pole zueinander weisen. Durch diese Magnete wird erreicht, daß die Schiebetüranlage aus einer abgesenkten Stellung, in der sich die Tür im allgemeinen in geschlossenem Zustand befindet, ohne großen Kraftaufwand herausgehoben und somit geöffnet werden kann. Hierzu können auch Elektromagnete eingesetzt werden, die über Sensoren an den Türgriffen gesteuert werden. Durch den Einsatz solcher Magnete wird zwar insbesondere bei relativ schweren Türen die Betätigung erleichtert, gleichwohl ist es aber erforderlich, die Tür von Hand zu öffnen und zu schließen.Finally, sliding door systems are known in which magnets are attached to the door flanks and to the door frames in such a way that their poles of the same name point towards one another. With these magnets it is achieved that the sliding door system can be lifted out of a lowered position, in which the door is generally in the closed state, without great effort and thus opened. Electromagnets can also be used for this, which are controlled by sensors on the door handles. The use of such magnets makes operation easier, particularly in the case of relatively heavy doors, but it is nevertheless necessary to open and close the door by hand.

Insbesondere in Eingangsbereichen von für den allgemeinen Publikumsverkehr zugänglichen Gebäuden werden Schiebetüren vollautomatisch z.B. mittels Bewegungsmeldern geöffnet und geschlossen. Die erforderlichen elektronischen Steuerungen sind allerdings relativ teuer.Especially in the entrance areas of buildings accessible to the general public, sliding doors are opened and closed fully automatically, for example using motion detectors. However, the required electronic controls are relatively expensive.

Der Erfindung liegt die Aufgabe zugrunde, eine elektromagnetische Türverriegelung zum Verriegeln einer Tür, insbesondere einer Schiebetür in einer ihrer Endstellungen anzugeben, die insbesondere zum Einsatz in Schienenfahrzeugen geeignet ist und nur geringen mechanischen und elektrischen Aufwand erfordert.The invention has for its object to provide an electromagnetic door lock for locking a door, in particular a sliding door in one of its end positions, which is particularly suitable for use in rail vehicles and requires little mechanical and electrical effort.

Gelöst wird diese Aufgabe bei der eingangs genannten elektromagnetischen Türverriegelung dadurch, daß an der Tür ein Anfahrstück vorgesehen ist, welches bei Erreichen einer Türendstellung einen ortsfest angebrachten Endschalter beaufschlagt, durch den ein zur Verriegelung der Tür vorgesehener Elektromagnet für eine vorbestimmte Zeitdauer aktiviert wird.This object is achieved in the electromagnetic door locking system mentioned at the outset in that a start-up piece is provided on the door which, when a door end position is reached, acts on a fixed limit switch by which an electromagnet provided for locking the door is activated for a predetermined period of time.

Vorteilhaft bei der Anwendung eines Elektromagneten ist, daß keine mechanischen Verriegelungselemente erforderlich sind, die relativ aufwendig und teuer sind, justiert werden müssen und relativ enge Einbautoleranzen erfordern und daß die Verriegelung und Entriegelung durch einfaches Ein- bzw. Abschalten des dem Magneten zugeführten Stromes bewirkt werden kann.It is advantageous when using an electromagnet that no mechanical locking elements are required, which are relatively complex and expensive, have to be adjusted and require relatively narrow installation tolerances, and that the locking and unlocking are effected by simply switching the current supplied to the magnet on and off can.

Ein weiterer Vorteil dieser Lösung liegt darin, daß diese Türverriegelung aufgrund ihrer wenigen und einfachen mechanischen Elemente auch bei extremen Umweltbedingungen und rauhem Einsatz zuverlässig arbeitet, so daß sie insbesondere zur Betätigung von Eisenbahnwaggontüren geeignet ist.Another advantage of this solution is that this door lock works reliably due to its few and simple mechanical elements even in extreme environmental conditions and rough use, so that it is particularly suitable for actuating railroad car doors.

Dadurch, daß die Verriegelung zeitlich begrenzt ist, kann in Kombination mit einer einfachen mechanischen Schließ- (oder Öffnungs-) einrichtung ein halbautomatischer Türbetrieb erzielt werden.Because the locking is limited in time, a semi-automatic door operation can be achieved in combination with a simple mechanical closing (or opening) device.

Das den Endschalter beaufschlagende Anfahrstück ist vorzugsweise federnd gelagert, so daß die Einbautoleranzen relativ hoch sein können.The approach piece acting on the limit switch is preferably spring-mounted, so that the installation tolerances can be relatively high.

Der Endschalter beaufschlagt vorzugsweise ein Zeitrelais zur Aktivierung des Elektromagneten für eine voreinstellbare Zeitdauer.The limit switch preferably acts on a time relay for activating the electromagnet for a presettable period of time.

Der Elektromagnet wirkt vorzugsweise auf das Anfahrstück ein und hält dadurch die Tür in ihrer Endstellung. Dies hat den Vorteil, daß die Tür auch schon vor Ablauf der vorbestimmten Zeitdauer ohne allzu großen Kraftaufwand von Hand geschlossen werden kann, da sich schon durch eine relativ geringe Verfahrbewegung der Tür das Anfahrstück vom Elektromagneten löst und damit die Tür entriegelt wird.The electromagnet preferably acts on the approach piece and thereby holds the door in its end position. This has the advantage that the door can be closed by hand even before the predetermined time has expired without too much effort, since the starting piece is released from the electromagnet by a relatively small movement of the door and the door is thus unlocked.

Die erfindungsgemäße Türverriegelung findet insbesondere in einer Vorrichtung zum Betreiben einer Schiebetür Anwendung, die in ihrer Offenstellung für eine vorbestimmte Zeitdauer verriegelt wird und die eine selbsttätige mechanische Schließeinrichtung zum Schließen der Tür nach Ablauf einer bestimmten Zeitdauer aufweist.The door lock according to the invention is used in particular in a device for operating a sliding door, which is locked in its open position for a predetermined period of time and which has an automatic mechanical closing device for closing the door after a certain period of time.

Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels an Hand der Zeichnung. Es zeigt:

Bei der in Figur 1 gezeigten schematischen Gesamtansicht ist eine Schiebetür 1 mit zwei Tragarmen 2, 3 versehen, mit denen diese in einer Führungs- und Halteschiene 4 läuft. Die mit durchgezogenen Linien dargestellte Schiebetür 1 befindet sich bei diesem Beispiel in ihrer geschlossenen Stellung, während mit gestrichelten Linien die Stellung in geöffnetem Zustand angedeutet ist.In the schematic overall view shown in FIG. 1, a sliding door 1 is provided with two support arms 2, 3 with which it runs in a guide and holding rail 4. The sliding door 1 shown with solid lines is in this example in its closed position, while the position in the open state is indicated by dashed lines.

An der Tür ist eine selbsttätige Schließeinrichtung vorgesehen, die einerseits aus einem an der Tür in einem Drehpunkt 15 schwenkbar gelagerten Hebelarm 12 sowie einer an diesem Hebelarm angreifenden Druckfederanordnung 13 und andererseits aus einer Ablaufschiene 11 gebildet ist, die ortsfest am Türrahmen befestigt ist. Diese Ablaufschiene ist nach Art einer schiefen Ebene geneigt und fällt in der in Figur 1 gezeigten Ebene in Richtung auf die geschlossene Stellung der Tür ab. In dieser Ablaufschiene 11 läuft eine Laufrolle 14 des Hebelarmes 12, der durch die Druckfederanordnung 13 in die mit durchgezogenen Linien gezeigte Drehstellung vorgespannt wird.An automatic locking device is provided on the door, which is formed on the one hand from a lever arm 12 pivotably mounted on the door at a pivot point 15 and a compression spring arrangement 13 engaging on this lever arm and on the other hand from a drain rail 11 which is fixedly attached to the door frame. This drain rail is inclined in the manner of an inclined plane and falls in the plane shown in FIG. 1 in the direction of the closed position of the door. In this drain rail 11 runs a roller 14 of the lever arm 12, which is biased by the compression spring assembly 13 in the rotational position shown by solid lines.

Befindet sich die Tür in geöffneter Stellung, so wird durch die Vorspannung des Hebelarmes 12 und die Neigung der Ablaufschiene 11, entlang der die Laufrolle 14 wie auf einer schiefen Ebene abläuft, eine in Richtung auf die geschlossene Stellung gerichtete Kraft auf die Schiebetür 1 ausgeübt und diese dadurch in ihre geschlossene Stellung zurückgeführt.If the door is in the open position, the pretension of the lever arm 12 and the inclination of the drain rail 11, along which the roller 14 runs as if on an inclined plane, cause one to open the closed position directed force exerted on the sliding door 1 and thereby returned to its closed position.

Mit der Schiebetür 1 ist ferner ein Halter 50 mit Anfahrstück 9 verbunden, welches beim Öffnen der Tür einen an einer ortsfesten Halterung 5 angebrachten Endschalter 7 betätigt. Durch das Anfahrstück 9 werden dabei Schalterkontakte geschlossen, so daß ein ebenfalls an der ortsfesten Halterung 5 befestigter Elektromagnet 6 über ein Zeitrelais 8 aktiviert wird. Das dadurch aufgebaute elektromagnetische Feld wirkt auf das aus entsprechendem Material gefertigte Anfahrstück 9 ein und hält dieses und damit die Schiebetür 1 mit einer bestimmten Mindest-Haltekraft in der geöffneten Stellung.With the sliding door 1, a holder 50 is also connected to the approach piece 9, which actuates a limit switch 7 attached to a fixed holder 5 when the door is opened. Switch contacts are closed by the approach piece 9, so that an electromagnet 6, which is also attached to the fixed holder 5, is activated via a time relay 8. The electromagnetic field thus created acts on the starting piece 9 made of the corresponding material and holds it and thus the sliding door 1 with a certain minimum holding force in the open position.

Da der Versorgungsstrom des Elektromagneten über das von dem Endschalter 7 beaufschlagte Zeitrelais 8 geführt wird, wird nach Ablauf einer einstellbaren Verzögerungszeit z.B. von etwa 1 - 20 Sekunden die Stromversorgung wieder unterbrochen. Dadurch bricht auch das elektromagnetische Feld zusammen, so daß die Haltekraft verschwindet und die Tür durch die selbsttätige Schließeinrichtung wieder in ihre geschlossene Stellung verfahren wird.Since the supply current of the electromagnet is conducted via the time relay 8 acted upon by the limit switch 7, after an adjustable delay time has elapsed, e.g. the power supply is interrupted again after about 1 - 20 seconds. This also breaks down the electromagnetic field, so that the holding force disappears and the door is moved back into its closed position by the automatic locking device.

Figur 2 zeigt die an der Führungs- und Halteschiene 4 befestigte ortsfeste Halterung 5 mit dem daran befestigten Endschalter 7 sowie eine Ausführungsform eines Elektromagneten 6. Der Endschalter 7 weist einen Kontaktarm 20 auf, der in einer schwenkbaren Lagerung 22 ruht und von der Kraft einer Feder 21 beaufschlagt wird, die diesen in die mit Pfeil 23 gekennzeichneten Richtung vorspannt. Die Halteplatte 5 und der Endschalter 7 sind so angebracht, daß der Kontaktarm 20 mit Gleitstück 24 durch das Anfahrstück 9 bei sich öffnender Tür entgegen der Kraftwirkung der Feder 21 geschwenkt wird. Durch diese Schwenkbewegung werden die Kontakte des Endschalters 7 geschlossen, so daß, wie oben beschrieben, über das Zeitrelais 8 ein Strom durch den Elektromagneten 6 fließen kann und das Anfahrstück 9 von dem erzeugten Magnetfeld festgehalten wird.Figure 2 shows the fixed to the guide and support rail 4 fixed bracket 5 with the attached limit switch 7 and an embodiment of an electromagnet 6. The limit switch 7 has a contact arm 20, which rests in a pivotable bearing 22 and by the force of a spring 21 is applied, which biases this in the direction indicated by arrow 23. The holding plate 5 and the limit switch 7 are attached so that the contact arm 20 with slider 24 is pivoted by the approach piece 9 when the door opens against the force of the spring 21. This pivoting movement closes the contacts of the limit switch 7, so that, as described above, a current can flow through the electromagnet 6 via the timing relay 8 and the starting piece 9 is held in place by the magnetic field generated.

Figur 3 zeigt einen Schnitt entlang der Linie A-A in Figur 2. In dieser Darstellung ist insbesondere das Profil der Führungs- und Halteschiene 4 zu erkennen, welches z.B. als Kugelführung ausgebildet ist. Die ortsfeste Halterung 5 ist bei dieser Ausführungsform auf der Führungsschiene befestigt. Ferner sind der Endschalter 7 mit Kontaktarm 20 sowie der Elektromagnet 6 zur erkennen.Figure 3 shows a section along the line A-A in Figure 2. In this representation, in particular the profile of the guide and holding rail 4 can be seen, which e.g. is designed as a ball guide. The fixed bracket 5 is attached to the guide rail in this embodiment. Furthermore, the limit switch 7 with contact arm 20 and the electromagnet 6 can be seen.

Figur 4 zeigt den an der Tür angebrachten Halter 50 mit Anfahrstück 9 im Detail. Aus dieser Darstellung geht insbesondere die axial federnde Lagerung des Anfahrstücks hervor, die durch eine Feder 41 bewirkt wird, so daß das Anfahrstück in Richtung des Doppelpfeils 42 beweglich ist und die Türlage nicht exakt vorgegeben sein muß. Dies hat den Vorteil, daß sowohl in offener als auch gegebenenfalls in geschlossener Stellung der Tür diese noch geringfügig verfahrbar ist. Das Anfahrstück 9 weist ferner stirnseitig einen abgeschrägten Bereich 43 auf, entlang dem das Gleitstück 24 des Kontaktarms 20 während des letzten Teils der Öffnungsbewegung der Tür entlanggleitet und somit die oben beschriebene Schwenkbewegung entgegen der Kraft der Feder 21 bewirkt. Weiterhin ist in dieser Darstellung ein Teil der Ablaufschiene 11 sowie der Führungs- und Halteschiene 4 gezeigt.Figure 4 shows the holder 50 attached to the door with the approach piece 9 in detail. This illustration shows in particular the axially resilient mounting of the starting piece, which is brought about by a spring 41, so that the starting piece is movable in the direction of the double arrow 42 and the door position does not have to be exactly predetermined. This has the advantage that the door can still be moved slightly, both in the open and possibly in the closed position. The approach piece 9 also has a beveled area 43 on the end face, along which the slide piece 24 of the contact arm 20 slides during the last part of the opening movement of the door and thus causes the above-described pivoting movement against the force of the spring 21. Furthermore, part of the drain rail 11 and the guide and holding rail 4 are shown in this illustration.

Figur 5 zeigt eine Ansicht gemäß Pfeil B in Figur 4. In dieser Darstellung ist die Führungs- und Halteschiene 4 zu erkennen, in der der Tragarm 2 der Schiebetür geführt ist. Ferner ist in dieser Darstellung die Druckfederanordung 13 gezeigt, die, wie mit Bezug auf Figur 1 beschrieben, den schwenkbaren Hebelarm 12 im Uhrzeigersinn vorspannt, wodurch die Laufrolle 14 auf der Ablaufschiene 11 abläuft und ein selbstätiges Schließen der Tür bewirkt. Ferner sind auch der Halter 50 mit Anfahrstück 9 sowie der abgeschrägte Bereich 43 an der Stirnseits des Anfahrstücks 9 zu erkennen, welches den Endschalter 7 beaufschlagt.Figure 5 shows a view according to arrow B in Figure 4. In this illustration, the guide and holding rail 4 can be seen, in which the support arm 2 of the sliding door is guided. Also shown in this illustration is the compression spring arrangement 13, which, as described with reference to FIG. 1, prestresses the pivotable lever arm 12 in a clockwise direction, as a result of which the roller 14 runs on the drain rail 11 and causes the door to close automatically. Furthermore, the holder 50 with the approach piece 9 and the chamfered area 43 on the end face of the approach piece 9, which acts on the limit switch 7, can also be seen.
