Grundsätzlich beruht die Funktion dieser allgemein bekannten elektrischen Türöffner darauf, daß der Anker den Wechsel blockieren oder freigeben kann, so daß die Schwenkfalle in ihrer Schließstellung gehalten oder für eine Öffnungsbewegung freigegeben wird. Bei den Türöffnern sind Ausführungen für einen Arbeitsstrombetrieb und für einen Ruhestrombetrieb bekannt, wobei beim Arbeitsstrombetrieb der Wechsel und somit die Schwenkfalle bei bestromter elektromagnetischer Betätigungseinrichtung freigegeben und in stromlosem Zustand blockiert wird. Die Ausführungen für den Ruhestrombetrieb weisen ein entgegengesetztes Betriebs- oder Schaltverhalten auf. Für jede dieser Ausführungen weist der Türöffner einen spezifischen Aufbau auf. Ein wahlweiser, umschaltbarer Arbeitsstrom- oder Ruhestrombetrieb ist bei den bekannten Türöffnern nicht möglich. Basically, the function of this well-known is based electric strike that the anchor is changing can block or release, so that the swivel trap in held in its closed position or for an opening movement is released. There are versions for the door openers a working current operation and known for a quiescent current operation, with the change in operating mode and thus the swing trap with energized electromagnetic actuator released and blocked when de-energized becomes. The explanations for the quiescent current operation an opposite operating or switching behavior. For each of these versions has a specific door opener Building on. An optional, switchable shunt or Quiescent current operation is not with the known door openers possible.

Der Erfindung liegt die Aufgabe zugrunde, einen elektrischen Türöffner zu schaffen, dessen konstruktive Ausbildung wahlweise einen Ruhestrombetrieb oder einen Arbeitsstrombetrieb zuläßt.The invention has for its object to provide an electric door opener, the design of which allows either a quiescent current operation or a working current operation.

Diese Aufgabe wird bei dem oben angegebenen Türöffner erfindungsgemäß dadurch gelöst, daß die Betätigungseinrichtung einen mit dem Anker gekoppelten Elektromagnetmechanismus aufweist und in dem Gehäuse verstellbar und wahlweise festlegbar ist in einer Position, bei dem der Anker bei unbestromtem Elektromagnetmechanismus in der Sperrstellung gehalten und bei bestromtem Elektromagnetmechanismus in die Freigabestellung bewegt ist (Arbeitsstrombetrieb), und in einer Position, bei dem der Anker bei unbestromtem Elektromagnetmechanismus in der Freigabestellung gehalten und bei bestromtem Elektromagnetmechanismus in die Sperrstellung bewegt ist (Ruhestrombetrieb). Somit kann die Voreinstellung der Betriebsweise des Türöffners ohne Umbau des Türöffners geändert werden. Dadurch wird auch eine geringere Teilevielfalt und eine Reduzierung der herzustellenden Varianten erzielt.This object is achieved according to the invention in the door opener specified above solved in that the actuator a having an electromagnetic mechanism coupled to the armature and adjustable in the housing and optionally fixable is in a position where the armature is deenergized Electromagnetic mechanism held in the locked position and with the electromagnet mechanism energized into the release position is moved (working current operation), and in a position in which the armature with the electromagnet mechanism de-energized held in the release position and with the electromagnet mechanism energized is moved into the blocking position (closed-circuit operation). Thus, the default operation of the Door opener can be changed without converting the door opener. Thereby there will also be fewer parts and a reduction of the variants to be produced.

Für eine einfache Umstellung oder Einstellung des Türöffners ist es zweckmäßig, daß die Betätigungseinrichtung eine Spulenhalterung aufweist, in der eine Spule des Elektromagnetmechanismus und eine Rückstellfeder für einen bewegbaren, mit Anker gekoppelten Spulenkern gelagert ist. Die Spulenhalterung kann als Einheit verstellt werden, so daß die Funktionsfähigkeit nach einer Umstellung nicht beeinträchtigt wird. Durch die Anordnung der Rückstellfeder in der Spulenhalterung wird eine auf den Anker übertragene Rückstellkraft bei einer Umstellung nicht verändert. Jedoch kann auch eine Rückstellfeder oder ein ähnliches federndes Element direkt an dem Anker angreifen. For a simple change or adjustment of the door opener it is expedient that the actuating device has a coil holder has, in which a coil of the electromagnetic mechanism and a return spring for a movable, with Anchor coupled coil core is stored. The coil holder can be adjusted as a unit, so that the functionality is not affected after a change. Due to the arrangement of the return spring in the coil holder is a restoring force transferred to the armature at a Changeover not changed. However, a return spring can also be used or a similar resilient element directly on the anchor attack.

Für seine Funktion als bewegbares Sperrelement ist der Anker vorzugsweise um eine Ankerachse schwenkbar gelagert und gabelförmig mit einer von zwei Sperrarmen begrenzten Freigabeöffnung für den Wechsel gestaltet. Dabei ist es zweckmäßig, wenn der Wechsel ein speziell für das Zusammenarbeiten mit dem Anker geformtes Teil und insbesondere einen Zapfen aufweist, der von dem Anker blockiert bzw. freigegeben wird. Der Zapfen ist beispielsweise eine Verlängerung des Wechsels in seiner Längsrichtung. Für eine Kopplung und Bewegungsübertragung vom Spulenkern auf den Anker kann am Spulenkern ein Mitnehmer zum Eingriff mit dem Anker angebracht sein.The anchor is responsible for its function as a movable blocking element preferably pivoted about an anchor axis and fork-shaped with a release opening limited by two locking arms designed for the change. It is advisable if the change is a specifically for working with the armature-shaped part and in particular a pin, which is blocked or released by the anchor. The Spigot is for example an extension of the change in its longitudinal direction. For a coupling and motion transmission from the spool core to the armature can be a driver on the spool core be attached to engage the anchor.

Ein erfindungsgemäßer elektrischer Türöffner weist ein Gehäuse 1 auf, in dem eine Türöffner-Schwenkfalle 2 um eine parallel zur Zeichenebene verlaufende Schwenkachse 3 schwenkbar gelagert und von einer Fallenfeder (nicht dargestellt) in ihre ausgeschwenkte Schließstellung vorgespannt ist. Ein Sperrhebel oder Wechsel 4 ist an einem am Gehäuse 1 befestigten Lagerstift 5 um eine Lagerachse 6 schwenkbar gelagert und mit Federkraft derart vorbelastet, daß eine Kontaktstelle am von der Lagerachse 6 entfernten, freien Endabschnitt 7 des Wechsels 4 gegen die Schwenkfalle 2 gedrückt ist.An electric door opener according to the invention has a housing 1 on, in which a door opener swivel latch 2 in parallel swivel axis 3 extending to the drawing plane stored and by a trap spring (not shown) in their pivoted closed position is biased. A locking lever or change 4 is attached to a housing 1 Bearing pin 5 pivotally mounted about a bearing axis 6 and with Spring force biased so that a contact point on the the bearing axis 6 removed, free end portion 7 of the change 4 is pressed against the swivel latch 2.

Der Endabschnitt 7 weist einen Zapfen 8 auf, der in Längsrichtung des Wechsels 4 hervorsteht. In einem dem Zapfen 8 benachbarten Endbereich des Gehäuses 1 ist ein Anker 9 angeordnet, der um eine senkrecht zur Zeichenebene verlaufende Ankerachse 10 schwenkbar gelagert ist. Der Anker 9 weist gabelartig einen ersten und einen zweiten Sperrarm 11 und 12 sowie eine zwischen den Sperrarmen 11, 12 liegende Öffnung oder Ausnehmung 13 auf, deren Größe bei entsprechender Stellung des Ankers 9 das Hindurchbewegen des Zapfens 8 beim Verschwenken des Wechsels 4 gestattet. Die parallel zur Zeichenebene liegende Schwenkebene des Ankers 9 befindet sich in Richtung der Ankerachse 10 versetzt neben dem Zapfen 8 des Wechsels 4 auf der zur Schwenkfalle 2 gegenüberliegenden Seite des Zapfens 8 bzw. des Wechsels 4 (in Fig. 1 vor dem Zapfen 8 bezüglich der Zeichenebene), wenn der Wechsel 4 an der Schwenkfalle 2 in Schließstellung anliegt.The end section 7 has a pin 8 which extends in the longitudinal direction of the change 4 protrudes. In a pin 8 An armature 9 is arranged adjacent to the end region of the housing 1. the one running perpendicular to the plane of the drawing Anchor axis 10 is pivotally mounted.

One in or next to the electromagnet 14 arranged coil spring (not shown) holds the movable coil core 17 in a retracted into the electromagnet 14 Position on the second stop 24 (see FIG. 2 and 4). When the coil 15 is energized, the coil core moves 17 against the force of the coil spring from the coil 15 out (to the right in the figures) until the driver 21 abuts the first stop 25 (FIGS. 1 and 3). To Switching off the current, the coil core 17 is back in the Coil 15 withdrawn.

In Abhängigkeit von Position A oder B der Halterung 18 befinden sich der erste und zweite Anschlag 24, 25 entsprechend ebenfalls in unterschiedlichen, paarweise parallel zur Spulenlängsachse versetzten Positionen. Auf diese Weise wird über den zwangsweise veränderten Weg des Mitnehmers 21 auch der Schwenkweg des Ankers 9 in der Weise unterschiedlich festgelegt, daß bei Position A nur der erste Sperrarm 11 und bei Position B nur der zweite Sperrarm 12 wirksam werden. Ferner ist der Ankerweg so eingestellt, daß sowohl in Position A als auch in Position B die Ausnehmung 13 zur Freigabe des Zapfens 8 angesteuert werden kann. Der Anker 9 kann also insgesamt drei wirksame Stellungen einnehmen, die durch die Positionen A oder B der Halterung 18 paarweise vorgegeben werden.Depending on position A or B of the bracket 18 the first and second stops 24, 25 accordingly also in different pairs in parallel to the longitudinal axis of the coil staggered positions. That way about the forcibly changed path of the driver 21 also the pivot path of the armature 9 varies in the way determined that only the first locking arm 11 and only the second locking arm 12 take effect at position B. Furthermore, the anchor path is set so that both in position A and in position B the recess 13 for release of the pin 8 can be controlled. The anchor 9 can therefore assume a total of three effective positions, which are determined by the Positions A or B of the bracket 18 are given in pairs become.

Fig. 1 und Fig. 2 zeigen die Einstellung des Türöffners für einen Ruhestrombetrieb in den beiden Stellungen des Türöffners bei bestromtem bzw. unbestromtem Elektromagnet 14. Die Halterung 18 ist hierbei in der gemäß Fig. 1 rechten Position A angeordnet und mit den Schrauben 19 am Gehäuse 1 festgelegt. Bei bestromtem Elektromagnet 14 ist der Spulenkern 17 ausgefahren. Der Mitnehmer 21 liegt an dem ersten Anschlag 25 an und hält den Anker 9 derart verschwenkt, daß der erste Sperrarm 11 in Bewegungsrichtung vor den Zapfen 8 greift und ihn an einer Bewegung hindert. Wenn der Elektromagnet 14 gemäß Fig. 2 stromlos gemacht wird, wird der Spulenkern 17 in die Spule 15 gezogen, so daß der Mitnehmer 21 den Anker 9 im Uhrzeigersinn in diejenige dargestellte Stellung verschwenkt, in der die Öffnung 13 des Ankers 9' im Schwenkweg des Zapfens 8 zu liegen kommt. Eine von dem Türöffner gesicherte Türe kann geöffnet werden, da die Schwenkfalle 2 bei gleichzeitigem Verschwenken des nun nicht blockierten Wechsels 4 verschwenkt werden kann. Damit ist bei Ruhestrom (Spule 15 unbestromt) die Schwenkfalle 2 geöffnet.Fig. 1 and Fig. 2 show the setting of the door opener for a quiescent current operation in the two positions of the door opener with energized or de-energized electromagnet 14. The Bracket 18 is in the right position according to FIG. 1 A arranged and fixed with the screws 19 on the housing 1. When the electromagnet 14 is energized, the coil core 17 extended. The driver 21 lies against the first stop 25 on and holds the anchor 9 pivoted such that the first Locking arm 11 engages in the direction of movement in front of the pin 8 and prevents him from moving. If the electromagnet 14 according to Fig. 2 is de-energized, the coil core 17 in the coil 15 pulled so that the driver 21, the armature 9 in Pivoted clockwise into the position shown, in which the opening 13 of the armature 9 'in the pivot path of the pin 8 comes to rest. A door secured by the door opener can be opened because the swivel latch 2 at the same time Swiveling the now not blocked change 4 swings can be. With quiescent current (coil 15 is de-energized) the swivel latch 2 opened.

Fig. 3 und 4 zeigen die Einstellung des Türöffners für einen Arbeitsstrombetrieb. Die Halterung 18 ist in die gemäß Fig. 3 linke Position B verschoben worden und mit den Schrauben 19 am Gehäuse 1 festgelegt. Bei unbestromter Spule 15 ist der Spulenkern 17 eingefahren, wobei der Mitnehmer 21 am ersten Anschlag 25 anliegt und den Anker 9 in der Sperrstellung hält und sein zweiter Sperrarm 12 den Weg des Zapfens 8 blockiert. Die Schwenkfalle 2 kann nicht verschwenkt und eine vom Türöffner gesicherte Türe kann somit nicht geöffnet werden. Beim Bestromen der Spule 15 fährt der Spulenkern 17 aus der Spule 15 und der Mitnehmer 21 verschwenkt den Anker 9 in die Freigabestellung (Anker 9'). Damit ist im Arbeitsstrombetrieb bei bestromter Spule 15 die Schwenkfalle 2 geöffnet. 3 and 4 show the setting of the door opener for one Working current operation. The bracket 18 is in the position shown in FIG. 3 left position B has been moved and with the screws 19 fixed on the housing 1. When the coil 15 is de-energized Coil core 17 retracted, the driver 21 on the first Stop 25 abuts and holds the armature 9 in the locked position and its second locking arm 12 blocks the path of the pin 8. The swivel latch 2 cannot be swiveled and one by the door opener the secured door cannot be opened. At the Current supply to the coil 15 moves the coil core 17 out of the coil 15 and the driver 21 pivots the armature 9 into the release position (Anchor 9 '). So that is in working current mode energized coil 15, the swing trap 2 opened.

Somit kann der erfindungsgemäße elektrische Türöffner für den Arbeitsstrombetrieb oder den Ruhestrombetrieb umgestellt werden, indem lediglich die Spulenhalterung 18 wahlweise in die jeweilige Position A oder B verschoben und darin festgelegt wird. Dazu muß weder das Gehäuse 1 geöffnet noch eine aufwendige Montagearbeit ausgeführt werden.Thus, the electric door opener according to the invention for the Open-circuit or closed-circuit operation are changed, by only the coil holder 18 optionally in the respective position A or B shifted and fixed therein becomes. To do this, neither the housing 1 has to be opened nor a complex one Assembly work to be carried out.
