Description

Die Erfindung betrifft einen Türöffner nach dem Ruhestromprinzip nach dem O-berbegriff des Anspruchs 1.The invention relates to a door opener according to the closed-circuit principle according to the O-term of claim 1.

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 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.Known are door openers according to the quiescent current principle, which are formed with a pivoting latch as a pivotable locking element, wherein the pivot latch in the locked state, the case of a lock a door record and thus lock the opening of the door or can release. The pivot latch is locked or released by an electromagnetically actuated locking member. In this case, an electromagnet is energized according to the quiescent current principle when the locking member is engaged and locks the locking element, whereby the case of the door lock is in engagement with the locking element and thus holds the door in its closed position. Door openers according to the quiescent current principle are often used in doors in escape and rescue routes, as in case of power failure, the locking member releases the locking element, and thus unlocks the door and the escape route is released.

Nachteilig bei diesen Türöffnern ist es, 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, diese aufdrücken muss.A disadvantage of these door openers is that the release of the locking element is only unreliable when applied during the interruption of the energization of the electromagnet, to release the pivot latch, pressure against the door and thus against the locking element. This can often be the case because the person who wants to open the door must press it open.

Aus der DE 38 12 313 A1 ist ein Türschloss mit einem Gehäuse bekannt, welches eine Stirnseite aufweist und eine Falle enthält, die durch eine Öffnung in der Stirnseite zwischen einer zurückgezogenen Stellung und einer aus dem Gehäuse vorspringenden Schließstellung bewegbar ist, in die sie durch eine Feder gedrängt ist und das weiterhin eine Sperreinrichtung aufweist, die aus einer passiven Stellung in eine Sperrstellung drehbar ist, in der sie die Bewegung der Falle aus der vorspringenden Stellung in die ins Gehäuse zurückgezogene Stellung verhindert. Die Sperreinrichtung ist durch einen Elektromagneten betätigbar.From DE 38 12 313 A1 discloses a door lock with a housing is known, which has an end face and a trap which is movable through an opening in the end face between a retracted position and a projecting from the housing closed position, in which they by a Spring is urged and further comprising a locking device which is rotatable from a passive position to a locking position in which it prevents the movement of the case from the projecting position into the position retracted into the housing. The locking device can be actuated by an electromagnet.

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 to form a door opener according to the quiescent current principle, which reliably releases the door lock, and which is inexpensive manufacturable.

Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.The object is solved by the features of claim 1.

Die Unteransprüche bilden vorteilhafte Ausgestaltungsmöglichkeiten der Erfindung.The subclaims form advantageous embodiments of the invention.

Die zuverlässige Freigabe der Türverriegelung wird 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 achieved by a cross latch as a locking element of the quiescent current door opener. A cross latch consists of two rotatably supported, one-sided wedge-shaped beveled trapping elements, which are supported in an arranged in the longitudinal direction of the door opener housing axis. In the locked state, the latch elements extend out of the housing of the door opener. The trapping elements of a cross latch have on their system on the inside of the Stulps eccentric, so that in the unlocked state, the latch elements can be pivoted and thereby withdrawn into the housing.

Der Türöffner weist als Steuerorgan einen Elektromagneten auf, 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 as a control member to an electromagnet, which energized locks the locking element. The control member can move or release a linkage depending on the switching state. At the linkage, a lever connects, which actuates a spring-loaded slide. By the control member and by the slider spring in slotted slides can take two layers. About the lever ratio of the reversing lever, the force of the control member and the spring force can be matched. This slider has a contour with a recess on which a locking member is guided over a roller. This locking member engages depending on the position of the slider in the locking element, whereby it is locked.

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.When the control element is energized and the linkage retracted, the slider is in a lower position, in which the locking member guided on the contour of the slider keeps the locking element of the door opener locked, and holds a door in engagement with the locking element in its closed position.

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 member is de-energized or the power fails, the linkage is released and the slider is brought by the slider spring in its upper position. As a result, the locking element guided by a second spring against the slider gives way and releases the locking element. The door can push back by pivoting the locking element in the forend and the housing of the door opener and thereby be opened.

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 switching contact, which is actuated by the door, prevents early energization of the control member so that locking of the locking element is prevented before the door is closed, otherwise closing the door would not be possible. This can be done for example by a reed contact, which is located in the forend of the door opener, and which corresponds to a permanent magnet in the door. Another, but more complex option would be an auxiliary trap, which mechanically detects the closed position of the door.

Im Nachfolgenden wird ein Ausführungsbeispiel in der Zeichnung anhand der Figuren näher erläutert.In the following an embodiment in the drawing with reference to the figures will be explained in more detail.

Dabei zeigen:

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, an inventive door opener 1, which operates on the quiescent current principle is shown. For the sake of clarity, only the elements required for the embodiment have been shown. The door opener 1 shown in Fig. 1 comprises a housing 2 and a face plate 3, via which the locking element 4, which is designed as a cross latch protrudes. After the closed-circuit principle, the control member 5 is then energized when the locking element 4 is locked. By the energization of the control member 5, the linkage 6 is retracted into the control member 5, whereby the linkage 6 actuates the rotatably mounted reversing lever 7 and the slider 8 is pressed against the force of the slide spring 9 down. On slide 8, the locking member 10 rests on a roller 11 and holds the locking element 4 locked.

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 control member 5 is de-energized, the linkage 6 is no longer maintained. The slide spring 9 pushes the slider 8 upwards, and the linkage 6 is pulled out of the control member 5 by the deflection lever 7. The locking member 10 with the roller 11 is guided along the contour of the slider 8 by the locking member spring 12 in the recess of the slider 8. As a result, the locking member 10 is guided out of engagement with the locking element 4 and releases it. This unlocked position is shown in Fig. 2.

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.If designed as a cross latch locking element 4, acted by pivoting a door not shown here, with a side acting on the cross latch force, the cross latch rotates against the spring 13 through the forend 3 into the housing 2 and gives the door free. By pivoting the cross latch, the door is reliably released.

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 spring 13 shown in the figures, a tension spring is used, whereby the locking element 4 is retracted after release equal through the forend 3 into the housing 2 into it. To lock the locking element 4 is then swung out of the housing 2 via the forend 3 again by the locking member 10.

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 locking element 4 before the door is again in its closed position, an auxiliary latch can be used. It would also be advantageous to equip the door opener with a reed contact in the forend, and to provide a permanent magnet in the door. The reed contact is connected in a series connection to the power supply of the control member 5 and thus prevents energization of the control member 5 before the door is in its closed position.

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. Durch die Verwendung der Rolle 11 zur Steuerung des Sperrglieds 10 an der Kontur des Schiebers 8 treten bei der Verschiebung niedrige Rollreibkräfte auf. 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 constructively simple structure is advantageous. An adaptation of the forces of the control member 5 and the slider spring 9 can be done very easily by the choice of leverage on the lever 7. For example, for a control member with a holding force of 10 N and a slider spring with about 20 to 30 N, a lever ratio of 1: 3 low. By using the roller 11 to control the locking member 10 at the contour of the slider 8 occur during the displacement low rolling friction forces. For doors in escape and rescue routes, which are unlocked by pressing an emergency button, only a receptacle for the locking element is required in the door. This can be very simple, for example, as a rectangular recess executed.
