Abstract

An electric door opener with a changer freeing or blocking a latch is described, which changer is detachably engaged with an electromagnetically operable inner armature. An electromagnetically controllable locking device prevents disengagement of the inner armature from the changer, e.g. as a result of an impact. The locking device has a locking lever provided with a detent and a control edge. The lever engages a corresponding projection on the inner armature. An outer armature acting on the control edge initially deflects the locking lever to overcome the locking action and, after a predetermined forward movement, drives the inner armature to release the changer.

Description

Die Erfindung betrifft einen elektrischen Türöffner mit einem Spulensatz, welcher auf einen federnd vorgespannten Innen- und Außenanker wirkt, und mit einem mit dem Innen­anker in Eingriff stehenden Wechsel zur Verriegelung einer Türöffnerfalle.The invention relates to an electric door opener with a coil set, which acts on a resiliently biased inner and outer anchor, and with a change in engagement with the inner anchor for locking a door opener latch.

Derartige elektrische Türöffner sind allgemein bekannt, wobei man eine Arbeitsstromausführung und eine Ruhestrom­ausführung unterscheiden kann. Grundsätzlich beruht die Funktion dieser Türöffner darauf, daß der Wechsel vom In­nenanker im Schwenkbereich der Türöffnerfalle gehalten wird, bis der Innenanker durch eine Betätigung des Spulen­satzes den Wechsel freigibt, welcher dann mit Hilfe einer Wechselfeder aus dem Schwenkbereich der Türöffnerfalle ge­bracht wird. Bei einer Arbeitsstromausführung wird der Innen­anker durch Bestromung des Spulensatzes entgegen der Vorspan­nung der Ankerfeder betätigt, während ein Türöffner in Ruhe­stromausführung nur bei abgeschaltetem Strom geöffnet werden kann.Such electric strikes are generally known, it being possible to distinguish between an open-circuit version and a closed-circuit version. Basically, the function of this door opener is based on the fact that the change from the inner anchor is held in the swivel area of the door opener latch until the inner anchor releases the change by actuating the coil set, which is then brought out of the swivel area of the door opener latch with the help of a change spring. In the case of a working current version, the inner armature is actuated by energizing the coil set against the pretension of the armature spring, while a door opener in the quiescent current version can only be opened when the current is switched off.

Obwohl derartige elektrische Türöffner äußerst zuverlässig und sicher arbeiten, kann es unter besonderen Umständen vorkommen, daß bei schlagartiger Gewalteinwirkung der Innen­anker außer Eingriff mit dem Wechsel gelangt und die Falle freigegeben wird.Although such electric strikes work extremely reliably and safely, it can happen under special circumstances that the sudden impact of the inner anchor disengages from the change and the latch is released.

Der Erfindung liegt die Aufgabe zugrunde, einen elektri­schen Türöffner der eingangs genannten Art anzugeben, wel­cher gegen ein kurzzeitiges Öffnen aufgrund einer Schlag­einwirkung besser gesichert ist.The invention has for its object to provide an electric door opener of the type mentioned, which is better secured against a short opening due to impact.

Diese Aufgabe wird dadurch gelöst, daß der Innenanker mit einem vom Spulensatz betätigbaren, federnd vorgespannten Riegel lösbar in einer sicheren Lage relativ zum Wechsel gehalten wird.This object is achieved in that the inner anchor is detachably held in a safe position relative to the change by a spring-loaded bolt which can be actuated by the coil set.

Die Erfindung hat den Vorteil, daß der Innenanker und der Wechsel aufgrund der federnden Vorspannung selbsttätig mit­einander verriegelt werden, so daß auch bei einer Schlag­einwirkung ein Aufspringen des Innenankers sicher verhin­dert wird. Die Entriegelung erfolgt über den Spulensatz, wenn auch der Innenanker sachgerecht und berechtigt frei­gegeben wird. Wird beispielsweise bei einem Arbeitsstrom-­Türöffner der Spulensatz bestromt, so wird der Sicherungs­riegel des Innenankers gelöst und der Innenanker wird nach erfolgter Freigabe ebenfalls durch den Spulensatz außer Eingriff mit dem Wechsel gebracht.The invention has the advantage that the inner anchor and the change are automatically locked together due to the resilient bias, so that the inner anchor is prevented from jumping open even when impacted. Unlocking takes place via the coil set if the inner anchor is released properly and with authorization. If, for example, the coil set is energized in an operating current door opener, the securing bolt of the inner anchor is released and the inner anchor is also disengaged from the change by the coil set after release.

Eine bevorzugte Ausgestaltung der Erfindung besteht darin, daß ein in einer Schwenkachse gelagerter Verriegelungshe­bel vorhanden ist, dessen freies Ende mit einer Nase ver­sehen ist, die in lösbarem Eingriff mit einer entsprechenden Rastkante am Innenanker steht, daß der Verriegelungshebel eine Steuerkante aufweist, die in der Weise in Eingriff mit einem vom Spulensatz betätigbaren Steuerhebel steht, daß bei einer Bewegung des Steuerhebels entlang der Steuerkante der Verriegelungshebel zur Freigabe des Innenankers ausge­lenkt wird.A preferred embodiment of the invention is that there is a locking lever mounted in a pivot axis, the free end of which is provided with a nose which is in releasable engagement with a corresponding latching edge on the inner anchor, that the locking lever has a control edge which in the manner is in engagement with a control lever which can be actuated by the coil set, that when the control lever moves along the control edge, the locking lever is deflected to release the inner armature.

Der Vorteil dieser Ausgestaltung liegt darin, daß die Ver­riegelung des Innenanker mit einer sehr kleinen Anzahl von Einzelteilen realisiert wird und daß eine raumsparende Anordnung möglich ist.The advantage of this embodiment is that the locking of the inner anchor is realized with a very small number of individual parts and that a space-saving arrangement is possible.

Eine besonders einfache Weiterbildung besteht darin, daß der Außenanker als Steuerhebel dient und daß der Außenan­ker gegenüber dem Innenanker mit einem vorgegebenen Frei­ gang zur Vorabansteuerung des Verriegelungshebels verse­hen ist. Durch diese Maßnahme erübrigt sich die Ausbil­dung eines separaten Steuerhebels.A particularly simple further development consists in the fact that the outer anchor serves as a control lever and that the outer anchor has a predetermined free space in relation to the inner anchor gear for advance control of the locking lever is provided. This measure makes the formation of a separate control lever unnecessary.

Der Freigang des Außenankers wird bevorzugt dadurch er­halten, daß der Außenanker und der Innenankder über einen Mitnehmer miteinander verbunden sind, der ein entsprechen­des Spiel aufweist.The clearance of the outer anchor is preferably obtained in that the outer anchor and the inner anchor are connected to one another via a driver which has a corresponding play.

Des weiteren kann es zur Einsparung von Einzelteilen vor­teilhaft sein, daß der Verriegelungshebel auf der Schwenk­achse des Wechsels gelagert ist.Furthermore, in order to save individual parts, it may be advantageous for the locking lever to be mounted on the pivot axis of the change.

Im Hinblick auch einer eventuell erforderlichen Justierung der Verriegelungsvorrichtung kann es vorteilhaft sein, daß die Rastkante des Innenankers aus einem mit einem Langloch versehenen und auf den Innenanker aufgeschraubten Blech­teil besteht.With regard to a possibly necessary adjustment of the locking device, it may be advantageous that the locking edge of the inner anchor consists of a sheet metal part provided with an elongated hole and screwed onto the inner anchor.

Eine Justierung erfolgt durch Verschieben des Blechteils entlang des Langloches.An adjustment is made by moving the sheet metal part along the elongated hole.

Eine vorteilhafte Weiterbildung besteht darin, daß das Blechteil mit einer das freie Ende des Verriegelungshebels übergreifenden Zunge zur Führung des Verriegelungshebels versehen ist. Durch diese Maßnahme wird eine sichere Füh­rung des Verriegelungshebels erreicht, die verhindert, daß das freie Ende des Sicherungshebels mit der Rastkante quer zur Schwenkbewegung ausgelenkt und auf diese Weise unkon­trolliert außer Eingriff mit der Rastnase gelangt.An advantageous further development consists in that the sheet metal part is provided with a tongue which overlaps the free end of the locking lever for guiding the locking lever. This measure ensures safe guidance of the locking lever, which prevents the free end of the locking lever with the locking edge from being deflected transversely to the pivoting movement and in this way coming out of engagement with the locking lug in an uncontrolled manner.

Die Vorspannung des Verriegelungshebels in Richtung auf die Rastnase des Innenankers wird bevorzugt dadurch erreicht, daß eine Druckfeder zwischen dem Sicherungshebel und einer Gehäusewand des Türöffners angeordnet ist.The bias of the locking lever in the direction of the latching lug of the inner anchor is preferably achieved in that a compression spring is arranged between the locking lever and a housing wall of the door opener.

Des weiteren kann es vorteilhaft sein, daß der Innenanker in seiner Schwenkrichtung mit Hilfe eines am Gehäuse ab­gestützten Abstandshalters in einem vorgegebenen Abstand vom freien Ende des Wechsels gehalten wird. Durch diese Maßnahme wird eine Stoßübertragung in Längsrichtung des Wechsels auf den Innenanker ausgeschaltet.Furthermore, it can be advantageous for the inner armature to be held in its pivoting direction at a predetermined distance from the free end of the change with the aid of a spacer supported on the housing. This measure eliminates shock transmission in the longitudinal direction of the change to the inner anchor.

Im folgenden wird die Erfindung anhand eines in Figuren dargestellten Ausführungsbeispiels weiter beschrieben.

  • Fig. 1 zeigt eine Seitenansicht eines elektrischen Tür­öffners bei abgenommenem Gehäusedeckel und
  • Fig. 2 zeigt eine Einzelheit gemäß Fig. 1.
In the following, the invention is further described using an exemplary embodiment shown in the figures.
  • Fig. 1 shows a side view of an electric door opener with the housing cover and removed
  • FIG. 2 shows a detail according to FIG. 1.

Die Fig. 1 veranschaulicht einen elektrischen Türöffner in Seitenansicht, bei welchem ein Gehäusedeckel 2 zum größten Teil entfernt ist, so daß der Blick auf die Einzelteile freigegeben ist. Ein Spulensatz 3, der über Anschlußklem­men 15 mit Spannung beaufschlagbar ist, wirkt auf einen Außenanker 17 und einen Innenanker 18, die beide auf einer gemeinsamen Achse 19 schwenkbar angeordnet sind. Der Außen­anker 17 weist gegenüber dem Innenanker 18 einen vorgegebe­nen Freigang auf, so daß bei einer Bestromung des Spulensatzes 3 zunächst der Außenanker allein angezogen wird und daß erst nach Durchlaufen des Freiganges der Innenanker 18 vom Außenanker 17 mitgenommen wird. Dies ist in dem hier dar­gestellten Beispiel durch einen hakenförmigen Mitnehmer 20 am freien Ende des Außenankers 17 realisiert, welcher den Innenanker 18 an seinem freien Ende untergreift. Der Außen­anker 17 ist durch eine Ankerfeder 4 belastet. Der Innenanker 18 ist mit einer Rastnase 21 zum Eingriff mit einer Rastkante 22 eines Wechsels 9 versehen, der da­zu dient, eine Türöffnerfalle 10 zu sperren oder freizu­geben. Wird der Innenanker 18 durch den Außenanker 17 nach außen geschwenkt, so gelangt die Rastkante 22 außer Eingriff mit der Rastnase 21 und der Wechsel 9 ist frei­ gegeben. In diesem Zustand kann die Türöffnerfalle 10 um ihre Fallenachse 13 geschwenkt werden, indem der Wechsel 9 entgegen der Kraft einer Wechselfeder 12 von einer Nase 23 an der Türöffnerfalle 10 weggedrückt wird. Der Wechsel 9 schwenkt dabei um eine Wechselachse 24. Ist dagegen die Rastkante 22 am Innenanker 18 eingerastet, so liegt der Wechsel 9 im Schwenkbereich der Nase 23 und verhindert eine Öffnung der Türöffnerfalle 10. Diese wird nach jeder Bewe­gung durch eine Fallenfeder 14 in die Ausgangslage zurück­gestellt, in welcher sie in dem hier gezeigten Beispiel bündig mit einem Schließblech 16 abschließt.Fig. 1 illustrates an electric door opener in side view, in which a housing cover 2 is largely removed, so that the view of the individual parts is released. A coil set 3, to which voltage can be applied via terminals 15, acts on an outer armature 17 and an inner armature 18, both of which are pivotably arranged on a common axis 19. The outer armature 17 has a predetermined clearance with respect to the inner armature 18, so that when the coil set 3 is energized, the outer armature is first attracted alone and that the inner armature 18 is not carried along by the outer armature 17 until after passing through the free space. In the example shown here, this is realized by a hook-shaped driver 20 at the free end of the outer anchor 17, which engages under the inner anchor 18 at its free end. The outer anchor 17 is loaded by an anchor spring 4. The inner anchor 18 is provided with a detent 21 for engagement with a detent edge 22 of a change 9, which serves to lock or release a door opener latch 10. If the inner armature 18 is pivoted outwards by the outer armature 17, the locking edge 22 is disengaged from the locking lug 21 and the change 9 is free given. In this state, the door opener latch 10 can be pivoted about its latch axis 13 by pushing the change 9 away from the nose 23 on the door opener latch 10 against the force of a change spring 12. The change 9 pivots about a change axis 24. On the other hand, if the latching edge 22 is engaged on the inner anchor 18, the change 9 lies in the pivoting range of the nose 23 and prevents the door opener latch 10 from opening. This is brought into the starting position by a latch spring 14 after each movement in which, in the example shown here, it ends flush with a striking plate 16.

Die Fig. 1 veranschaulicht denjenigen Zustand des elektri­schen Türöffners, in welchem der Wechsel 9 am Innenanker 18 eingerastet ist. In dieser Lage ist der Außenanker 17 über einen Verriegelungshebel 7 verriegelt. Die Verriegelung wird über den Spulensatz 3 aufgehoben, wie nachfolgend im einzelnen noch beschrieben wird. Solange der Spulensatz 3 nicht bestromt ist, kann die Sperre des Wechsels 9 nicht aufgehoben werden.Fig. 1 illustrates that state of the electric door opener in which the change 9 is engaged on the inner anchor 18. In this position, the outer anchor 17 is locked by a locking lever 7. The lock is released via the coil set 3, as will be described in detail below. As long as the coil set 3 is not energized, the lock on the change 9 cannot be released.

Der Verriegelungshebel 7 ist in dem dargestellten Beispiel als flaches Blechteil ausgebildet, welches auf der Wechsel­achse 24 schwenkbar angeordnet ist. Ferner ist der Verrie­gelungshebel 7 über eine Druckfeder 25 vorgespannt, die sich an einer Gehäusewand 8 abstützt. Die Schwenkbewegung des Verriegelungshebels 7 verläuft senkrecht zur Längsach­se des Innenankers 18. Im verriegelten Zustand hintergreift eine Nase 6 am Verriegelungshebel 7 eine entsprechende Na­se oder Kante 26 am Innenanker 18, was in Fig. 1 rein sche­matisch dargestellt ist. Wird der Verriegelungshebel 7 nach außen geschwenkt, so gibt er den Innenanker 18 frei.The locking lever 7 is formed in the example shown as a flat sheet metal part which is pivotally arranged on the change axis 24. Furthermore, the locking lever 7 is biased by a compression spring 25, which is supported on a housing wall 8. The pivoting movement of the locking lever 7 runs perpendicular to the longitudinal axis of the inner anchor 18. In the locked state, a nose 6 on the locking lever 7 engages behind a corresponding nose or edge 26 on the inner anchor 18, which is shown purely schematically in FIG. 1. If the locking lever 7 is pivoted outwards, it releases the inner anchor 18.

Die Freigabe des Verriegelungshebels 7 erfolgt über eine Steuerkante 5, die in Eingriff mit dem Außenanker 17 steht. Wird der Außenanker 17 verschwenkt, so gleitet sein freies Ende entlang der Steuerkante 5, die hier durch einen keil­förmigen Verlauf des freien Endes des Verriegelungshebels 7 gebildet wird, und bewirkt auf diese Weise eine Auslenkung des Verriegelungshebels 7.The locking lever 7 is released via a control edge 5 which is in engagement with the outer anchor 17. If the outer anchor 17 is pivoted, its free end slides along the control edge 5, which is formed here by a wedge-shaped course of the free end of the locking lever 7, and in this way causes the locking lever 7 to deflect.

Als weitere Einzelheit verdeutlicht die Fig. 1, daß der Innenanker 18 über einen Abstandshalter 27, der sich am Türöffnergehäuse abstützt, in einem vorgegebenen Abstand von der Stirnseite des Wechsels 9 gehalten wird. Eine Impulsübertragung vom Wechsel 9 auf den Außenanker 18 in Längsrichtung des Wechsels 9, beispielsweise bei einer Schlageinwirkung, ist durch diese Maßnahme ausgeschlossen. Damit wird gegebenenfalls eine Entlastung der Innenanker-­Verriegelung erreicht.As a further detail, FIG. 1 illustrates that the inner anchor 18 is held at a predetermined distance from the end face of the change 9 via a spacer 27, which is supported on the door opener housing. A pulse transmission from the change 9 to the outer anchor 18 in the longitudinal direction of the change 9, for example in the event of an impact, is excluded by this measure. This may relieve the internal anchor locking.

In Fig. 2 ist weiter veranschaulicht, auf welche Weise die Verriegelung des Innenankers erfolgen kann. Gleiche Teile wie in Fig. 1 sind mit gleichen Bezugszeichen versehen. Im Unterschied zu Fig. 1 ist die mit der Nase 6 des Ver­riegelungshebels 7 zusammenwirkende Nase bzw. Kante 26 an einer Blechlasche 29 ausgebildet, die auf dem Innenanker 18 (hier nicht dargestellt) angebracht ist. Die Lasche 29 ist mit einer Öffnung 30 und einem Langloch 31 zur Befestigung und Justierung auf dem Innenanker versehen. Mit Hilfe eines Bolzens (nicht dargestellt) wird die Lasche 29 zunächst schwenkbar auf dem Innenanker angeordnet, wobei über das Langloch 31 eine Auslenkung zu Justierzwecken möglich ist. Zur endgültigen Befestigung wird die Lasche 29 im Langloch 31 verschraubt.FIG. 2 further illustrates the way in which the inner anchor can be locked. The same parts as in Fig. 1 are given the same reference numerals. In contrast to FIG. 1, the nose or edge 26 which interacts with the nose 6 of the locking lever 7 is formed on a sheet metal tab 29 which is attached to the inner anchor 18 (not shown here). The tab 29 is provided with an opening 30 and an elongated hole 31 for attachment and adjustment on the inner anchor. With the aid of a bolt (not shown), the tab 29 is first pivotally arranged on the inner anchor, with the elongated hole 31 allowing deflection for adjustment purposes. For final attachment, the tab 29 is screwed into the elongated hole 31.

Ferner weist die Lasche 29 eine Zunge 28 auf, welche den Verreigelungshebel 7 in der Weise übergreift, daß dieser zwischen der Zunge 28 und dem darunter liegenden Innen­anker eine genaue Führung erhält und ein Ausweichen des Verriegelungshebels senkrecht zur Zeichenebene verhindert wird.Furthermore, the tab 29 has a tongue 28 which engages over the locking lever 7 in such a way that it receives precise guidance between the tongue 28 and the underlying inner anchor and prevents the locking lever from escaping perpendicular to the plane of the drawing.

Die Fig. 2 veranschaulicht denjenigen Zustand, in wel­chem der Außenanker 17 vom Spulensatz angezogen ist. Durch den Verlauf der Steuerkante 5 ist dabei der Verriegelungs­hebel 7 nach außen geschwenkt und außer Eingriff mit der Kante 26 gebracht.2 illustrates the state in which the outer armature 17 is attracted to the coil set. Due to the course of the control edge 5, the locking lever 7 is pivoted outward and brought out of engagement with the edge 26.

Damit ist der Innenanker freigegeben. Er kann daher durch den Mitnehmer 20 außer Eingriff mit dem Wechsel gebracht werden. Aus Gründen der Übersichtlichkeit sind diese Teile in Fig. 2 nicht dargestellt.The inner anchor is now released. It can therefore be disengaged from the change by the driver 20. For reasons of clarity, these parts are not shown in FIG. 2.
