Abstract
Description
Die Erfindung betrifft einen Türöffner nach dem Ruhestromprinzip nach dem Oberbegriff
des Anspruchs 1.The invention relates to a door opener according to the quiescent current principle
of
Bekannt sind Türöffner nach dem Ruhestromprinzip, die mit einer Schwenkfalle als schwenkbares Verriegelungselement ausgebildet sind, wobei die Schwenkfalle in gesperrtem Zustand die Falle eines Schlosses einer Tür aufnehmen kann und damit das Öffnen der Tür sperren bzw. freigeben kann. Die Schwenkfalle wird dabei durch ein elektromagnetisch betätigbares Sperrglied gesperrt bzw. freigegeben. Dabei ist nach dem Ruhestromprinzip ein Elektromagnet bestromt, wenn sich das Sperrglied im Eingriff befindet und das Verriegelungselement sperrt, wodurch die Falle des Türschlosses sich im Eingriff mit dem Verriegelungselement befindet und damit die Tür in ihrer Geschlossenlage hält. Türöffner nach dem Ruhestromprinzip werden häufig in Türen in Flucht- und Rettungswegen eingesetzt, da bei Stromausfall das Sperrglied das Verriegelungselement freigibt, und damit die Tür entsperrt und der Fluchtweg freigegeben wird.Door openers based on the closed-circuit principle are known, which have a pivot latch are designed as a pivotable locking element, the pivot latch can lock the latch of a door lock when locked and can lock or unlock the opening of the door. The swing trap will locked or released by an electromagnetically actuated locking member. Here, an electromagnet is energized according to the closed-circuit principle, if the locking member is in engagement and locks the locking element, whereby the latch of the door lock engages with the locking element located and thus keeps the door in its closed position. Door opener based on the closed-circuit principle are often used in doors in escape and rescue routes, since the locking element releases the locking element in the event of a power failure, and thus the door is unlocked and the escape route is released.
Nachteilig bei diesen Türöffnern ist, dass die Freigabe des Verrieglungselements nur unzuverlässig erfolgt, wenn während der Unterbrechung der Bestromung des Elektromagneten, zur Freigabe der Schwenkfalle, Druck gegen die Tür und somit gegen das Verriegelungselement aufgebracht wird. Dies kann häufig der Fall sein, da die Person, welche die Tür öffnen möchte möchte, diese aufdrücken muss.The disadvantage of these door openers is that the release of the locking element only unreliable if, during the interruption of the current supply to the Electromagnets, to release the swivel latch, pressure against the door and thus is applied against the locking element. This can often be the case because the person who wants to open the door has to push it open.
Der Erfindung liegt die Aufgabe zugrunde, einen Türöffner nach dem Ruhestromprinzip auszubilden, der die Türverriegelung zuverlässig freigibt, und welcher kostengünstig fertigbar ist. The invention has for its object a door opener according to the closed-circuit principle train who releases the door lock reliably, and which inexpensive is producible.
Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.The object is solved by the features of
Die Unteransprüche bilden vorteilhafte Ausgestaltungsmöglichkeiten der Erfindung.The subclaims form advantageous design options for the invention.
Die zuverlässige Freigabe der Türverriegelung wird erfindungsgemäß durch eine Kreuzfalle als Verriegelungselement des Ruhestrom-Türöffners erreicht. Eine Kreuzfalle besteht aus zwei drehbar abgestützten, einseitig keilartig abgeschrägten Fallenelementen, welche in einer in Längsrichtung des Türöffnergehäuses angeordneten Achse abgestützt sind. Im verriegelten Zustand erstrecken sich die Fallenelemente aus dem Gehäuse des Türöffners heraus. Die Fallenelemente einer Kreuzfalle weisen an ihrer Anlage an der Innenseite des Stulps Excenter auf, so dass im entriegelten Zustand die Fallenelemente verschwenkt werden können und dadurch in das Gehäuse zurückgezogen werden.The reliable release of the door lock is according to the invention by a Cross latch reached as a locking element of the closed-circuit electric strike. A Cross latch consists of two rotatably supported, wedge-like bevels on one side Latch elements, which are in the longitudinal direction of the door opener housing arranged axis are supported. In the locked state, the extend Latch elements out of the door opener housing. The trap elements a cross trap point to their system on the inside of the cuff excenter on, so that the latch elements are pivoted in the unlocked state can be retracted into the housing.
Der Türöffner weist ein Steuerorgan auf, beispielsweise einen Elektromagneten, welcher bestromt das Verriegelungselement sperrt. Das Steuerorgan kann je nach Schaltzustand ein Gestänge einziehen oder freigeben. An das Gestänge schließt sich ein Umlenkhebel an, welcher einen federbelasteten Schieber betätigt. Durch das Steuerorgan und durch die Schieberfeder kann der in Langlöchem geführte Schieber zwei Lagen einnehmen. Über das Hebelverhältnis des Umlenkhebels kann die Kraft des Steuerorgans und die Federkraft aufeinander abgestimmt werden. Dieser Schieber weist eine Kontur mit einer Einbuchtung auf, an welcher ein Sperrglied über eine Rolle geführt wird. Dieses Sperrglied greift abhängig von der Stellung des Schiebers in das Verriegelungselement ein, wodurch dieses gesperrt wird.The door opener has a control element, for example an electromagnet, which energizes the locking element. The tax authority can ever pull in or release a linkage according to the switching status. To the linkage is followed by a bell crank that operates a spring-loaded slide. Through the control element and the slide spring can in the elongated holes guided slider take two layers. About the lever ratio of the bell crank the force of the control element and the spring force can be coordinated become. This slide has a contour with an indentation which a locking member is guided over a roller. This locking member intervenes from the position of the slide in the locking element, whereby this is blocked.
Ist das Steuerorgan bestromt und das Gestänge eingezogen, befindet sich der Schieber in einer unteren Stellung, in welcher das an der Kontur des Schiebers geführte Sperrglied das Verriegelungselement des Türöffners gesperrt hält, und eine sich im Eingriff mit dem Verriegelungselement befindliche Tür in ihrer Geschlossenlage hält. If the control element is energized and the linkage retracted, the is located Slide in a lower position, in which the contour of the slide guided locking member keeps the locking element of the door opener locked, and a door in engagement with the locking element in its closed position holds.
Wird das Steuerorgan stromlos geschaltet oder fällt der Strom aus, so wird das Gestänge freigegeben und der Schieber wird durch die Schieberfeder in seine obere Stellung gebracht. Dadurch weicht das durch eine zweite Feder gegen den Schieber geführte Sperrelement zurück und gibt das Verriegelungselement frei. Die Tür kann durch Verschwenken das Verriegelungselement in den Stulp und das Gehäuse des Türöffners zurückdrücken und dadurch geöffnet werden.If the control device is switched off or the power fails, it will Linkage is released and the slide is pushed into its by the slide spring brought up position. This gives way to a second spring Slider guided locking element back and releases the locking element. The door can be swiveled into the faceplate and the locking element push the housing of the door opener back and open it.
Ein elektrischer Schaltkontakt, der durch die Tür betätigt wird, verhindert eine frühzeitige Bestromung des Steuerorgans, damit ein Sperren des Verriegelungselements verhindert wird, bevor die Tür geschlossen ist, da sonst ein Schließen der Tür nicht möglich wäre. Dies kann beispielsweise durch einen Reedkontakt erfolgen, der sich im Stulp des Türöffners befindet, und der mit einem Permanentmagneten in der Tür korrespondiert. Eine weitere, aber aufwändigere Möglichkeit wäre eine Hilfsfalle, welche mechanisch die Geschlossenlage der Tür detektiert.An electrical switch contact that is actuated by the door prevents one early energization of the control element, thus blocking the Locking element is prevented before the door is closed, otherwise it would not be possible to close the door. This can be done for example by a Reed contact, which is in the faceplate of the door opener, and with corresponds to a permanent magnet in the door. Another one, however A more complex option would be an auxiliary trap, which mechanically Closed position of the door detected.
Im Nachfolgenden wird ein Ausführungsbeispiel in der Zeichnung anhand der Figuren näher erläutert.In the following an embodiment in the drawing based on the figures explained in more detail.
Dabei zeigen:
- Fig. 1
- einen Türöffner in verriegelter Stellung mit geöffnetem Gehäuse in der Seitenansicht;
- Fig. 2
- den Türöffner gemäß Fig. 1 in entriegelter Stellung;
- Fig. 3
- den Türöffner in einer Ansicht auf die Stulpseite gesehen.
- Fig. 1
- a door opener in the locked position with the housing open in side view;
- Fig. 2
- 1 in the unlocked position;
- Fig. 3
- seen the door opener in a view on the faceplate.
In den Figuren ist ein erfindungsgemäßer Türöffner 1, welcher nach dem Ruhestromprinzip
arbeitet, dargestellt. Um die Übersichtlichkeit zu wahren, wurden nur
die für das Ausführungsbeispiel erforderlichen Elemente dargestellt. Der in Fig. 1
dargestellte Türöffner 1 umfasst ein Gehäuse 2 und einen Stulp 3, über den das
Verriegelungselement 4, das als Kreuzfalle ausgeführt ist, übersteht. Nach dem
Ruhestromprinzip ist das Steuerorgan 5 dann bestromt, wenn das Verriegelungselement
4 gesperrt ist. Durch die Bestromung des Steuerorgans 5 ist das Gestänge
6 in das Steuerorgan 5 eingezogen, wodurch das Gestänge 6 den drehbar gelagerten
Umlenkhebel 7 betätigt und den Schieber 8 gegen die Kraft der Schieberfeder
9 nach unten gedrückt hält. Am Schieber 8 liegt das Sperrglied 10 über
eine Rolle 11 an und hält das Verriegelungselement 4 gesperrt.In the figures is a
Wird das Steuerorgan 5 stromlos geschaltet, so wird das Gestänge 6 nicht mehr
gehalten. Die Schieberfeder 9 schiebt den Schieber 8 nach oben, und das Gestänge
6 wird durch den Umlenkhebel 7 aus dem Steuerorgan 5 herausgezogen.
Das Sperrglied 10 mit der Rolle 11 wird entlang der Kontur des Schiebers 8 durch
die Sperrgliedfeder 12 in die Einbuchtung des Schiebers 8 geführt. Dadurch wird
das Sperrglied 10 aus dem Eingriff mit dem Verriegelungselement 4 geführt und
gibt dieses frei. Diese entriegelte Stellung ist in Fig. 2 dargestellt.If the
Wird das als Kreuzfalle ausgebildete Verriegelungselement 4, durch ein Verschwenken
einer hier nicht weiter dargestellten Tür, mit einer seitlich auf die
Kreuzfalle wirkenden Kraft beaufschlagt, so dreht sich die Kreuzfalle gegen die
Feder 13 durch den Stulp 3 in das Gehäuse 2 hinein und gibt die Tür frei. Durch
das Verschwenken der Kreuzfalle wird die Tür zuverlässig freigegeben.Is the
Denkbar ist auch, dass an Stelle der in den Figuren dargestellten Feder 13 eine
Zugfeder eingesetzt wird, wodurch das Verriegelungselement 4 nach Freigabe
gleich durch den Stulp 3 in das Gehäuse 2 hinein eingezogen wird. Zum Verrieglen
wird dann das Verriegelungselement 4 durch das Sperrglied 10 wieder aus
dem Gehäuse 2 über den Stulp 3 ausgeschwenkt.It is also conceivable that instead of the
Um ein Sperren des Verriegelungselements 4 zu verhindern, bevor sich die Tür
wieder in ihrer Geschlossenlage befindet, kann eine Hilfsfalle verwendet werden.
Vorteilhaft wäre auch, den Türöffner mit einem Reedkontakt im Stulp auszurüsten,
und in der Tür einen Permanentmagneten vorzusehen. Der Reedkontakt wird in
einer Reihenschaltung zur Stromversorgung des Steuerorgans 5 geschaltet und
verhindert somit eine Bestromung des Steuerorgans 5 bevor die Tür sich in ihrer
Geschlossenlage befindet. To prevent locking of the
Vorteilhaft ist der konstruktiv einfache Aufbau. Eine Anpassung der Kräfte des
Steuerorgans 5 und der Schieberfeder 9 kann sehr einfach durch die Wahl der
Hebelverhältnisse am Umlenkhebel 7 erfolgen. Beispielsweise ist für ein Steuerorgan
mit einer Haltekraft von 10 N und einer Schieberfeder mit etwa 20 bis 30 N
ein Hebelverhältnis von 1:3 günstig. Besonders vorteilhaft ist die Verwendung der
Rolle 11 zur Steuerung des Sperrglieds 10 an der Kontur des Schiebers 8, da bei
der Verschiebung niedrige Rollreibkräfte auftreten. Für Türen in Flucht- und Rettungswegen,
welche durch Betätigung eines Notauf - Schalters entriegelt werden,
ist in der Tür nur eine Aufnahme für das Verriegelungselement erforderlich. Diese
kann sehr einfach, beispielsweise als rechteckige Aussparung, ausgeführt sein. The simple construction is advantageous. An adjustment of the powers of the
