Description

Die Erfindung betrifft einen elektrischen Türöffner nach dem Oberbegriff des Anspruchs 1.The invention relates to an electric door opener according to the preamble of claim 1.

Derartige Türöffner sind beispielweise aus der DE 19607684 C1 und der EP 0922821 A2 bekannt.Such door openers are known for example from DE 19607684 C1 and EP 0922821 A2.

Die DE 19607684 C1 offenbart einen gattungsgemäßen Türöffner mit einer elektromagnetischen Betätigungseinrichtung, welche durch eine Magnetspule mit einem in ihr beweglichen Spulenkern zur Betätigung des Ankers sowie einen die Bewegung des Ankers begrenzenden Drehanschlag gebildet ist. Diese Betätigungseinrichtung für den Anker ist wahlweise in einer Position für einen Arbeitsstrombetrieb (Fig. 8 und 9) und in einer Position für einen Ruhestrombetrieb (Fig. 6 und 7) festlegbar. Der rechteckförmige Anker weist eine Ausnehmung mit einem daran anschließenden Schlitz auf, welche mit dem von der Drehachse abgewandten T-förmigen Ende des Wechsels zusammenwirkt.DE 19607684 C1 discloses a generic door opener with an electromagnetic actuator, which is formed by a magnetic coil with a movable therein coil core for actuating the armature and a movement limiting the armature rotation stop. This actuator for the armature is selectively fixed in a position for a working power operation (FIGS. 8 and 9) and in a position for a quiescent current operation (FIGS. 6 and 7). The rectangular anchor has a recess with a subsequent slot, which cooperates with the remote from the axis of rotation T-shaped end of the change.

In der EP 0922821 A2 wird die elektromagnetische Betätigungseinrichtung durch den Elektromagneten und das Anschlagelement gebildet, welche ebenso ein Umschalten zwischen Arbeitsstrom- und Ruhestrombetrieb ermöglicht. Die Ausbildung des Ankers und des Wechsels sowie deren Zusammenwirken erfolgt gleichermaßen wie bei DE 19607684 C1.In EP 0922821 A2, the electromagnetic actuator is formed by the electromagnet and the stop element, which also allows switching between working current and quiescent current operation. The formation of the armature and the change and their interaction takes place in the same way as in DE 19607684 C1.

Die bei den oben beschriebenen Türöffnern erforderlichen Bauteile zur Umrüstung oder Umschaltung des elektrischen Türöffners vom Ruhestrombetrieb in den Arbeitsstrombetrieb schaffen bereits eine gute Lösung, erfordern aber eine exakte Ausbildung der Ausnehmung und des zugehörigen Schlitzes des Ankers und des komplementär dazu ausgebildeten Wechselkopfes, um das gewünschte Zusammenwirken zu ermöglichen.The components required for the above-described door openers for conversion or switching of the electric door opener from quiescent operation in the working flow already provide a good solution, but require an exact design of the recess and the associated slot of the armature and the complementary trained replaceable head to the desired interaction to enable.

Der Erfindung liegt daher die Aufgabe zugrunde, einen elektrischen Türöffner anzugeben, dessen konstruktive Ausgestaltung mit einfachen Mitteln einen Ruhestrombetrieb oder einen Arbeitsstrombetrieb ermöglicht.The invention is therefore an object of the invention to provide an electric door opener, the structural design enables by simple means a quiescent current operation or a working power operation.

Diese Aufgabe wird mit den im Anspruch 1 angegebenen Merkmalen gelöst. 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 with the features specified in claim 1. Thus, the default setting of the operation of the door opener without changing the door opener can be changed. As a result, a smaller number of parts and a reduction of the variants to be produced is achieved.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen enthalten.Advantageous embodiments of the invention are contained in the subclaims.

Für eine einfache Umstellung oder Einstellung des Türöffners ist es zweckmäßig, daß die Betätigungseinrichtung eine Spulenhalterung aufweist, in der eine Spul- der Betätigungseinrichtung 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 conversion or adjustment of the door opener, it is expedient that the actuating device has a coil holder, in which a coil of the actuating device and a return spring for a movable, coupled with armature spool core is mounted. The coil holder can be adjusted as a unit, so that the functionality is not affected after a changeover. The arrangement of the return spring in the coil holder a transmitted to the armature restoring force is not changed in a changeover. However, a return spring or similar resilient element may also directly engage the armature.

Für seine Funktion als bewegbares Sperrelement ist der Anker vorzugsweise um eine Ankerachse schwenkbar gelagert. 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.For its function as a movable blocking element of the anchor is preferably pivotally mounted about an anchor axis. It is expedient if the change has a specially designed for working with the armature part and in particular a pin which is blocked or released by the anchor. The pin 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, a driver for engagement with the armature can be attached to the spool core.

Zum Ausführen der Umstellung des Türöffners ist es zweckmäßig, daß die Betätigungseinrichtung bzw. die Spulenhalterung in dem Gehäuse verschiebbar und in zwei Rastpositionen festlegbar ist, die dem Ruhestrombetrieb bzw. dem Arbeitsstrombetrieb zugeordnet sind. Dabei ist es vorteilhaft, wenn der Türöffner Bedienelemente zum Verschieben und Festlegen der Betätigungseinrichtung bzw. der Spulenhalterung aufweist, die von der Außenseite des Gehäuses zugänglich sind.To carry out the conversion of the door opener, it is expedient that the actuating device or the coil holder in the housing is displaceable and fixable in two locking positions, which are assigned to the quiescent current operation or the working current operation. It is advantageous if the door opener has controls for moving and fixing the actuator or the coil holder, which are accessible from the outside of the housing.

In einer bevorzugten Ausführungsform weist der Türöffner eine Vorschaltelektronik auf, die eine Spannungsversorgung, insbesondere eine Nennspannung von 12V bis 24V mit Toleranzgrenzen von 9V bis 30V, mit Gleichstrom oder mit Wechselstrom gestattet. Damit kann der Türöffner an die jeweils gegebene Stromversorgung angepaßt werden.In a preferred embodiment, the door opener on a ballast, which allows a power supply, in particular a rated voltage of 12V to 24V with tolerance limits of 9V to 30V, with direct current or alternating current. Thus, the door opener can be adapted to the respective given power supply.

Um das Betriebsverhalten des Türöffners im Arbeitsstrombetrieb zu optimieren, kann er eine Vorschaltelektronik mit einer Zerhackerschaltung aufweisen, die einen Gleichstromausgang zur Spule in eine wechselstromförmige Rechteckspannung umformt. Damit wird das Öffnen des Türöffners unter Vorlast verbessert.In order to optimize the performance of the door opener in working current operation, it may have a ballast with a chopper circuit that converts a DC output to the coil in an AC rectangular voltage. This improves the opening of the door opener under pre-load.

Nachfolgend wird die Erfindung anhand eines Ausführungsbeispiels eines erfindungsgemäBen Türöffners unter Bezugnahme auf Zeichnungen näher erläutert. Es zeigt:

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 in which a door opener pivot latch 2 is pivotally mounted about a pivot axis 3 extending parallel to the plane of the drawing and is biased by a latch spring (not shown) into its pivoted closed position. A locking lever or change 4 is pivotally mounted on a housing 1 fixed to the bearing pin 5 about a bearing axis 6 and biased by spring force such that a contact point on the bearing axis 6 remote, free end portion 7 of the change 4 is pressed against the pivotal 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 portion 7 has a pin 8 which protrudes in the longitudinal direction of the change 4. In an end portion of the housing 1 adjacent to the pin 8, an armature 9 is arranged, which is mounted pivotably about an armature axis 10 extending perpendicular to the plane of the drawing. The armature 9 has a fork-like first and second locking arm 11 and 12 and a between the locking arms 11, 12 lying opening or recess 13, the size of which in the corresponding position the armature 9 allows the passage of the pin 8 when pivoting the change 4. The pivot plane of the armature 9 lying parallel to the plane of the drawing is offset in the direction of the armature axis 10 next to the pin 8 of the change 4 on the side of the pin 8 or of the change 4 opposite the pivoting catch 2 (in front of the pin 8 with respect to FIG Drawing plane) when the change 4 is applied to the pivot latch 2 in the closed position.

In seiner Freigabestellung nimmt der Anker 9 eine solche Schwenkstellung ein, daß sich der Zapfen 8 beim Verschwenken des Wechsels 4 durch die Öffnung 13 zwischen den beiden Sperrarmen 11 und 12 hindurchbewegen kann (das Bezugszeichen 9' bezeichnet den Anker 9 in Freigabestellung). Wenn der Anker 9 aus seiner Freigabestellung in eine der beiden Schwenkrichtungen verschwenkt ist, befindet er sich in Sperrstellung; in welcher sich einer der Sperrarme 11, 12 vor den Zapfen 8 erstreckt und damit ein Verschwenken des Zapfens 8 und somit des Wechsels 4 verhindert, wodurch gleichzeitig die Schwenkfalle 2 in ihrer Schließstellung blockiert ist. Die Sperrstellung und die Freigabestellung des Ankers 9 bzw. 9' sind in den Fig. 1 bzw. 2 für den Ruhestrombetrieb und in Fig. 3 bzw. 4 für den Arbeitsstrombetrieb dargestellt.In its release position, the armature 9 assumes such a pivotal position that the pin 8 can move through the opening 13 between the two locking arms 11 and 12 during pivoting of the change 4 (the reference numeral 9 'denotes the armature 9 in the release position). When the armature 9 is pivoted from its release position in one of the two pivoting directions, it is in the locked position; in which one of the locking arms 11, 12 extends in front of the pin 8 and thus prevents pivoting of the pin 8 and thus of the change 4, whereby at the same time the pivotal latch 2 is blocked in its closed position. The blocking position and the release position of the armature 9 and 9 'are shown in Figs. 1 and 2 for the quiescent current operation and in Fig. 3 and 4 for the working current operation.

Im Gehäuse 1 ist des weiteren ein Elektromagnet 14 enthalten, der eine Spule (nicht dargestellt) und einen entlang einer Spulenlängsachse 16 bewegbaren Hubmagneten oder Spulenkern 17 aufweist. Der Elektromagnet 14 ist beispielsweise mit einer Schnappverbindung an einer Halterung 18 fest angebracht, die an einer Innenseite des Gehäuses 1 in Längsrichtung des Gehäuses 1 und der Spulenlängs-achse 16 verschoben und in zwei unterschiedlichen, z.B. durch Rastungen vorgegebenen Positionen A (siehe Fig. 1 und Fig. 2) und B (siehe Fig. 3 und Fig. 4) durch von außen schraubbare Senkkopfschrauben 19 festgelegt werden kann.The housing 1 further includes an electromagnet 14 which has a coil (not shown) and a lifting magnet or coil core 17 which is movable along a coil longitudinal axis 16. The electromagnet 14 is fixedly mounted, for example with a snap connection to a holder 18 which is displaced on an inner side of the housing 1 in the longitudinal direction of the housing 1 and the coil longitudinal axis 16 and in two different, for example by notches predetermined positions A (see FIG and FIG. 2) and B (see FIGS. 3 and 4) can be fixed by countersunk screws 19 which can be screwed from the outside.

Die Senkkopfschrauben 19 sind hierzu durch Langlöcher 26 in der Gehäusewand geführt. Die Position A oder B wird gewählt, je nachdem ob der Türöffner im Ruhestrombetrieb oder im Arbeitsstrombetrieb eingesetzt wird.The countersunk screws 19 are guided for this purpose by slots 26 in the housing wall. The position A or B is selected, depending on whether the door opener is used in standby mode or in working current operation.

Ein vorderes freies Ende 20 des Spulenkerns 17 weist einen Mitnehmer 21 auf, der beispielsweise auf den Spulenkern 17 aufgepreBt ist. Der Mitnehmer 21 enthält eine Aussparung 22, in der ein Schaltvorsprung 23 des Ankers 9 eingreift. An der Halterung 18 sind sich gegenüberliegend ein erster und zweiter Anschlag 24 und 25 für den Mitnehmer 21 ausgebildet, die den Bewegungsweg des Mitnehmers 21 in Richtung der Spulenlängsachse 16 begrenzen. Eine in oder neben dem Elektromagnet 14 angeordnete Schraubenfeder (nicht dargestellt) hält den bewegbaren Spulenkern 17 in einer in den Elektromagnet 14 zurückgezogenen Stellung am zweiten Anschlag 24 (siehe Fig. 2 und 4). Wenn die Spule 15 bestromt ist, bewegt sich der Spulenkern 17 gegen die Kraft der Schraubenfeder aus der Spule 15 heraus (nach rechts in den Figuren), bis der Mitnehmer 21 an dem ersten Anschlag 25 anliegt (Fig. 1 und Fig. 3). Nach Abschalten des Stromes wird der Spulenkern 17 wieder in die Spule 15 zurückgezogen.A front free end 20 of the spool core 17 has a driver 21 which is for example pressed onto the spool core 17. The driver 21 includes a recess 22 in which a switching projection 23 of the armature 9 engages. On the holder 18 are opposite a first and second stop 24 and 25 are formed for the driver 21, which limit the movement path of the driver 21 in the direction of the coil longitudinal axis 16. A coil spring (not shown) disposed in or adjacent the solenoid 14 holds the movable spool core 17 in a position retracted into the solenoid 14 at the second stop 24 (see FIGS. 2 and 4). When the coil 15 is energized, the coil core 17 moves out of the coil 15 against the force of the coil spring (to the right in the figures) until the catch 21 abuts against the first stop 25 (FIGS. 1 and 3). After switching off the current, the spool core 17 is pulled back into the coil 15.

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 holder 18, the first and second stops 24, 25 are also correspondingly also in different positions offset in pairs parallel to the longitudinal axis of the coil. In this way, the pivoting path of the armature 9 is determined differently in the manner on the forced way changed the driver 21 in the manner that at position A, only the first locking arm 11 and at position B, only the second locking arm 12 are effective. Further, the anchor travel is adjusted so that both in position A and in position B, the recess 13 can be controlled to release the pin 8. The armature 9 can thus occupy a total of three effective positions, by the Positions A or B of the holder 18 are given in pairs.

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 solenoid 14. The holder 18 is in this case in the position shown in FIG. 1 right A and arranged with the screws 19 on Housing 1 fixed. When energized solenoid 14 of the bobbin 17 is extended. The driver 21 abuts against the first stop 25 and keeps the armature 9 pivoted so that the first locking arm 11 engages in the direction of movement in front of the pin 8 and prevents it from moving. When the electromagnet 14 is de-energized as shown in FIG. 2, the coil core 17 is pulled into the coil 15, so that the driver 21 pivots the armature 9 in the clockwise direction in the position shown, in which the opening 13 of the armature 9 'in the pivoting of the Pin 8 comes to rest. A door secured by the door opener can be opened, since the pivot latch 2 can be pivoted with simultaneous pivoting of the now not blocked change 4. This is at quiescent current (coil 15 without power), the pivot latch 2 is open.

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.Fig. 3 and 4 show the setting of the door opener for a working power operation. The holder 18 has been moved to the left in FIG. 3 position B and fixed with the screws 19 on the housing 1. When energized coil 15 of the bobbin 17 is retracted, wherein the driver 21 abuts the first stop 25 and the armature 9 holds in the locked position and its second locking arm 12 blocks the path of the pin 8. The pivotal latch 2 can not be pivoted and thus a door secured by the door opener can not be opened. When energizing the coil 15 of the bobbin 17 moves out of the coil 15 and the driver 21 pivots the armature 9 in the release position (armature 9 '). Thus, the swing latch 2 is open in working current operation with energized coil 15.

Somit kann der erfindungsgemäBe 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 erfindungsgemäBe electric door opener for the working power operation or the quiescent current operation can be changed by only the coil holder 18 is selectively moved to the respective position A or B and fixed therein. For this purpose, neither the housing 1 must be opened nor a complex assembly work to be performed.

Im Gehäuse 1 des Türöffners ist des weiteren eine Vorschaltelektronik enthalten, die eine universelle Spannungsversorgung, insbesondere mit einer Nennspannung von 12V bis 24V mit Toleranzgrenzen von 9V bis 30V bei Gleich- oder Wechselstrom gestattet.In the housing 1 of the door opener further includes a ballast electronics, which allows a universal power supply, in particular with a nominal voltage of 12V to 24V with tolerance limits of 9V to 30V with DC or AC.

Die Elektronik enthält eine eingebaute Zerhackerschaltung, die den Gleichstromausgang zur Spule 15 in eine Rechteckspannung annähert. Damit wird eine Wechselstromansteuerung simuliert, bei der das Öffnen des Türöffners unter Vorlast durch das dynamische Aufschlagen der Verriegelungseinheit durch den Spulenkern 17 verbessert wird.The electronics include a built-in chopper circuit which approximates the DC output to the coil 15 into a square wave voltage. Thus, an AC drive is simulated, in which the opening of the door opener under preload is improved by the dynamic impact of the locking unit by the spool core 17.
