Definitions

  • the invention relates to a door opener.
  • Door openers are known. They each comprise a pivoting latch which, in the locking position, engages with a corresponding part of mainly a door leaf, such as a latch, in such a way that opening of the door leaf is prevented. If the pivot latch is released with respect to its pivoting movement, it can pivot away from the latch in the direction of the unlocking position in the event of a door-opening attempt. As a result, the corresponding part of the door leaf can be moved past the pivoting latch and thus the respective door leaf can be opened.
  • a locking lever is pivotally mounted on and pivoted away from the pivotal latch. Pivot and locking lever abut each other via mutually corresponding surfaces.
  • the DE 25 22 973 A1 proposes, firstly, to use a leaf spring which is attached at one end to a side facing away from the locking lever of a designated as a hinged armature locking anchor, and the other end is free. This free end is in blocking position of the locking anchor on a latch.
  • Blocking position means that the locking arm prevents pivoting of the locking lever from a blocking position in the unlocked position.
  • Locking position means that the locking lever in this position prevents pivoting of the pivoting latch from a locking position in the unlocked position.
  • Locking position means that the pivoting latch is prevented from pivoting in one direction, which would cause unlocking of the corresponding door leaf and thus make it possible to open it.
  • the object of the invention is to at least reduce the disadvantages of the prior art.
  • an electric door opener that is to say a door opener which is electrically actuated.
  • the door opener is known to have a pivotal latch which is pivotally mounted between the unlocked position and the locking position.
  • the pivot latch is adapted to be brought into locking position with a corresponding part of a located in the closed position rotary wing in such a way that the rotary wing is prevented from opening.
  • the corresponding part is the case of a door lock.
  • the door lock is mounted in a known manner on or in here designed as a door sash.
  • the pivot latch is further configured, are pivoted in unlocking usually by opening the rotary wing out of engagement with the corresponding part, so that the opening movement of the rotary wing is released.
  • the rotary wing can therefore be opened.
  • the door opener also has a locking lever, which is also mounted in a known manner about a first axis on the pivot latch in the locked position and away from it in the unlocked position. In the blocking position, the locking lever prevents the pivoting latch from pivoting out of the locking position toward the unlocking position.
  • the door opener comprises a locking anchor, which is also mounted in a known manner about a second axis on the locking lever in the blocking position and away from it in the release position. In blocking position prevents the Sperranker pivoting of the locking lever from the locked position in the unlocked position.
  • the door opener on an electromagnet, which is adapted, when actuated, so when energized, the barrier armor electromagnetically in the direction of release position or in an opposite direction to urge or move.
  • the door opener is designed so that the locking lever is prevented in blocking position its blocking position with respect to the other door opener in a further pivoting of the locking lever from the locked position out towards the pivot latch and back again.
  • a shaking on the door could indeed cause the locking lever is repeatedly repeatedly pivoted from its locked position in the direction of pivoting latch and back again.
  • this does not affect the position of the locking anchor, there is no danger that the locking armor could be "shaken" from its blocking position both in the direction of the release position and in the opposite direction. This increases the safety in the operation of the door opener without increasing the energy required to open the door leaf.
  • the aforementioned design of the door opener is carried out in such a way that the locking armature is designed so that it is in the blocking position outside of a defined by the Rothverschwenken Rothverschwenk Schemes the locking lever. Ie. the locking lever is unable to transmit its movement to the locking armor in any way directly or indirectly.
  • This solution has the advantage that no additional parts are required to ensure the retention of the blocking position corresponding position of the locking armature with respect to the other door opener.
  • the door opener as a design according to the invention further comprises a stop which limits a pivoting of the locking armature in the blocking position.
  • the stop is arranged so that it is outside the entire pivoting range of the locking lever. Ie. the stop does not affect the pivoting of the locking lever.
  • this design of the door opener thus defines the stop and not the locking lever, the blocking position of the locking armature or its pivoting from its release position out in the blocking position.
  • the aforementioned design of the door opener be such that a the locking lever facing surface of the locking armature on which the locking lever passes in its Rothverschwenken, at least partially follows a circumferential line of a circle whose center is a point on the first axis. This first axis runs perpendicular to a surface defined by the circle. Since the locking lever is pivoted about the same, first axis, it can no longer happen here alone due to the design of this surface of the locking armature that the locking armature is moved by the locking lever.
  • the design of the door opener may be such that the aforementioned surface of the locking armature is formed so that the locking lever rests in the locking position and along its further pivoting in the direction of the pivotal latch on the following section of the circumference of the locking armature.
  • the locking lever serves as a blocking position end stop of the locking armature.
  • the section of this surface following the circumference effectively prevents the locking armature from being moved out of its actual locking position in the direction of the locking lever.
  • the locking armature is biased towards locking position.
  • This has the advantage that the locking armor is urged in the direction of blocking position solely on account of the prestress acting on it. If the bias is realized by one or more mechanical elements such as return springs, no electrical energy is required to urge the locking armature in the blocking position. Since the locking armor can not leave his blocking position, the bias can be designed as in known door openers that have no "vibration protection". They can also, as explained in more detail later, be made weaker. Ie. the device that realizes this bias can be designed or even reduced in terms of the applied biasing force and thus also in terms of their dimensions in the usual manner.
  • This solution also allows the use of a bistable electromagnet, which is energized only when the Speranker is to change position, and is able to magnetically located in the release or blocking position Speranker without energization to hold against any pretensioning forces.
  • This solution is particularly energy-saving, so that the use of rechargeable batteries can be considered as energy supply of the door opener.
  • the locking armor or the locking lever can move on a side facing the locking lever or the locking armature, at or with which the locking lever passes when it is pivoted further
  • the bias is so great that the guide portion rests along the defined by the Rothverschwenken Rothverschwenk Schemes the locking lever on Speranker or locking lever.
  • the bias is also so low that the guide portion is not able to push the locking armature away from the locking lever so towards release position. A pivoting of the locking armature due to the prestressed bearing guide section in the direction of the release position is thus prevented.
  • This solution has the advantage that the aforementioned restoring elements can be dispensed with in the case of the section of the locking armature following a circular line. Another advantage is that in the case of biased storage of the locking anchor in the direction of blocking position, the aforementioned surface must follow no circular line. In addition, bumps or other undesirable geometric shapes in the thus serving as a running surface bearing surface of the locking lever or locking lever can be compensated. Apart from that, it is also possible to compensate for inaccuracies in the positioning of the locking armature with respect to the locking lever to a certain extent, for example, due to different thermal expansion behavior or to ensure a certain distance between the locking armature and locking lever. Overall, this solution improves safety during operation.
  • a door system comprises a revolving door wing as the aforementioned rotary wing. Furthermore, it comprises a door lock mounted on or in the revolving door leaf with a latch as the aforementioned corresponding part. Finally, the door system includes one of the aforementioned door opener. Ie. Door opener and door lock are arranged in the closed position of the revolving door wing to each other so that the pivot latch in the locked position on the latch prevents the revolving door from opening.

  • the pivot latch 20 When opening the rotary wing, the pivot latch 20, if not locked, in the opening direction, so here to the front of the door opener 1 without cover shown, pivoted so far that the case can be moved past the pivot latch 20.
  • the pivot latch 20 has on its side facing away from the locking portion 21 side a projection as a locking portion 22 which cooperates with a locking portion 31 of the locking lever 30 in a likewise known manner.
  • the blocking section 31 is formed by means of a surface extending in the direction of the pivoting catch 20 and the rear wall 11 of the housing 10. Thus, this area extends obliquely to the rear wall 11.
  • the pivotal latch 20 is therefore pressed against the locking portion 31 with its locking portion 22 in the aforementioned case in the aforementioned case with mechanical loading by the aforementioned case. If the locking lever 30 is not blocked, the pivoting latch 20 can push the locking lever 30 over its locking portion 22 by sliding along the inclined surface of the locking portion 31 away. Thereby, the locking portion 22 is moved past the locking portion 31, and the pivot latch 20 can release the case, so the associated rotary wing can be opened.

Ie. the blocking portions 32, 41 are located as in FIG FIG. 1a shown in blocking position not necessarily to each other. As a result, the aforementioned shaking on the pivot latch 20 in particular in this type of door systems is possible. Another reason for this game is due to the fact that the blocking sections 32, 41 otherwise would not easily be able to move past one another in the event of intentional pivoting of the locking armature 40.

Description

Die Erfindung betrifft einen Türöffner.The invention relates to a door opener.

Türöffner an sich sind bekannt. Sie umfassen jeweils eine Schwenkfalle, die in Verriegelungsstellung derart mit einem korrespondierenden Teil hauptsächlich eines Türflügels, wie einer Schlossfalle, in Eingriff zu steht, dass ein Öffnen des Türflügels verhindert ist. Ist die Schwenkfalle hinsichtlich ihrer Schwenkbewegung freigegeben, kann sie bei einem Türflügel-Öffnungsversuch von der Falle weg in Richtung Entriegelungsstellung schwenken. Dadurch können das korrespondierende Teil des Türflügels an der Schwenkfalle vorbei bewegt und damit der betreffende Türflügel geöffnet werden. Ein Sperrhebel ist auf die Schwenkfalle zu und von ihr weg schwenkbar angeordnet. Schwenkfalle und Sperrhebel liegen über miteinander korrespondierende Flächen aneinander an. Diese Flächen sind so ausgebildet, dass ein Verschwenken der Schwenkfalle in Richtung Entriegelungsstellung ein Schwenken des Sperrhebels von der Schwenkfalle weg zur Folge hat. Um dies in Verriegelungsstellung des Türöffners zu verhindern, gibt es noch einen Sperranker. Befindet sich der Sperranker mit dem Sperrhebel in Eingriff, ist dieser gehindert bzw. blockiert, von der Schwenkfalle weg geschwenkt zu werden. D. h. die Schwenkfalle kann nicht in Entriegelungsstellung schwenken. Damit kann das korrespondierende Teil des Türflügels nicht am Türöffner vorbei bewegt und geöffnet werden. Der Türflügel ist also in Schließstellung verriegelt.Door openers are known. They each comprise a pivoting latch which, in the locking position, engages with a corresponding part of mainly a door leaf, such as a latch, in such a way that opening of the door leaf is prevented. If the pivot latch is released with respect to its pivoting movement, it can pivot away from the latch in the direction of the unlocking position in the event of a door-opening attempt. As a result, the corresponding part of the door leaf can be moved past the pivoting latch and thus the respective door leaf can be opened. A locking lever is pivotally mounted on and pivoted away from the pivotal latch. Pivot and locking lever abut each other via mutually corresponding surfaces. These surfaces are designed so that a pivoting of the pivotal latch in the unlocked position has a pivoting of the locking lever away from the pivotal latch result. To prevent this in the locked position of the door opener, there is still a locking anchor. If the locking arm is engaged with the locking lever, it is prevented from being pivoted away from the pivoting latch. Ie. The pivot latch can not pivot in unlocked position. Thus, the corresponding part of the door can not be moved past the door opener and opened. The door is locked so in the closed position.

Durch Windlasten oder auch durch Rütteln am Türflügel kann es vorkommen, dass sich der Sperranker sukzessive vom Sperrhebel weg und somit aus seiner Blockierstellung in Richtung Freigabestellung bewegt. Dies kann also dazu führen, dass der Sperrhebel und damit die Schwenkfalle freigegeben werden und damit der Türflügel geöffnet werden kann, obwohl der Türöffner den Türflügel eigentlich verriegeln soll.By wind loads or by shaking the door, it may happen that the Speranker successively moves away from the locking lever and thus from its blocking position in the direction of the release position. This can thus cause the locking lever and thus the pivot latch are released and thus the door can be opened, although the door opener should actually lock the door.

Um dieser Gefahr zu begegnen, wird in der DE 20 2010 010 895 U1 vorgeschlagen, die Schwenkfalle mittels einer seitlich angeordneten Kugelverrastung festzusetzen. Ein Nachteil besteht darin, dass diese Verrastung bei Öffnen des korrespondierenden Türflügels überdrückt werden muss. D. h. es ist mehr Öffnungsenergie notwendig. Ein anderer Nachteil besteht in dem konstruktiven Aufwand und den damit im Zusammenhang stehenden Kosten. Nicht zuletzt könnte sich die Kugel verklemmen, sodass die Betriebssicherheit nicht mehr gegeben wäre.In order to counteract this danger, in the DE 20 2010 010 895 U1 proposed to fix the pivotal latch by means of a laterally arranged Kugelverrastung. A disadvantage is that this locking must be suppressed when opening the corresponding door leaf. Ie. it is necessary more opening energy. Another disadvantage is the design effort and the associated costs. Not least, the ball could jam, so that the reliability would no longer exist.

Die DE 25 22 973 A1 schlägt erstens vor, eine Blattfeder zu nutzen, die einerends an einer dem Sperrhebel abgewandten Seite eines als Klappanker bezeichneten Sperrankers befestigt ist, und deren anderes Ende frei ist. Dieses freie Ende liegt in Blockierstellung des Sperrankers an einer Rastnase an. Blockierstellung bedeutet, dass der Sperranker ein Schwenken des Sperrhebels aus einer Sperrstellung in Richtung Entsperrstellung verhindert. Sperrstellung bedeutet, dass der Sperrhebel in dieser Stellung ein Schwenken der Schwenkfalle aus einer Verriegelungsstellung in Richtung Entriegelungsstellung verhindert. Verriegelungsstellung bedeutet, dass die Schwenkfalle an einem Schwenken in eine Richtung gehindert ist, die ein Entriegeln des korrespondierenden Türflügels bewirken und damit dessen Öffnen ermöglichen würde. In einer Freigabestellung, in der der Sperranker das vorgenannte Schwenken des Sperrhebels nicht mehr blockiert oder verhindert, also freigibt, befindet sich das freie Ende der Blattfeder aus Sicht des Sperrhebels hinter der Rastnase und im freien Innenraum des Türöffnergehäuses. Ein Nachteil ist, dass unklar ist, was passiert, wenn sich die Blattfeder mit ihrem freien Ende mit der Rastnase verhakt oder verbogen wird. Wird der Sperrhebel weiter in Richtung Schwenkfalle bewegt, wird der Sperranker aufgrund der Form seiner Ausnehmung zum Aufnehmen des ihm zugewandten Endes des Sperrhebels weiter in Richtung Sperrhebel geschwenkt. Dies kann dazu führen, dass das freie Ende der Blattfeder außer Eingriff mit der Rastnase gelangt. Dies birgt die Gefahr, dass das freie Ende beim Zurückschwenken des Sperrankers nicht mehr mit der Rastnase in Eingriff gelangt. Damit kann die Blattfeder nicht mehr ihre Funktion erfüllen, und es entstehen wieder die vorgenannten Probleme beim Rütteln am korrespondierenden Türflügel. Ein anderer Nachteil besteht auch hier in dem konstruktiven Aufwand und den damit im Zusammenhang stehenden Kosten.The DE 25 22 973 A1 proposes, firstly, to use a leaf spring which is attached at one end to a side facing away from the locking lever of a designated as a hinged armature locking anchor, and the other end is free. This free end is in blocking position of the locking anchor on a latch. Blocking position means that the locking arm prevents pivoting of the locking lever from a blocking position in the unlocked position. Locking position means that the locking lever in this position prevents pivoting of the pivoting latch from a locking position in the unlocked position. Locking position means that the pivoting latch is prevented from pivoting in one direction, which would cause unlocking of the corresponding door leaf and thus make it possible to open it. In a release position in which the Speranker no longer blocks or prevents the aforementioned pivoting of the locking lever, thus releasing the free end of the leaf spring is from the perspective of the locking lever behind the latch and in the free interior of the door opener housing. A disadvantage is that it is unclear what happens when the leaf spring with its free end with the latch hooked or bent. If the locking lever is moved further in the direction of the pivoting latch, the locking armature is pivoted further in the direction of the locking lever due to the shape of its recess for receiving the end of the locking lever facing it. This can lead to the free end of the leaf spring disengaged from the detent. This entails the risk that the free end no longer engages with the detent when pivoting back the locking arm. Thus, the leaf spring can no longer fulfill their function, and it again creates the aforementioned problems when shaking the corresponding door leaf. Another disadvantage here is the design effort and the associated costs.

Zweitens ist vorgeschlagen, den Sperranker so anzuordnen, dass sich dessen Schwenkachse an einer der Schwenkfalle abgewandten Seite des Sperrhebels befindet. Bei dieser Lösung ist allerdings nicht erkennbar, wodurch die Gefahr eines Entriegelns des Sperrhebels aufgrund des Rüttelns am korrespondierenden Türflügel verhindert wird. Nicht zuletzt erlaubt diese Lösung nicht, die Teile des Türöffners in gewohnter Manier anordnen zu können. Auch ist der konstruktive Aufwand aufgrund der speziell abzustützenden Rückstellfeder für den Sperrhebel relativ hoch, verbunden mit entsprechenden Kosten.Secondly, it is proposed to arrange the locking armature such that its pivot axis is located on a side of the locking lever facing away from the pivoting latch. In this solution, however, is not recognizable, whereby the risk of unlocking the locking lever due to the shaking on the corresponding door is prevented. Not least, this solution does not allow to arrange the parts of the door opener in the usual manner. Also, the design effort due to the particular spring to be supported for the locking lever is relatively high, associated with corresponding costs.

Es wird in der WO 2005/080718 A1 einen Türöffner vorgeschlagen, nach welchem diese Schutz gegen Rütteln durch die Lagerung des Sperrankers in; seinem Massenmittelpunkt erreicht wird.It will be in the WO 2005/080718 A1 proposed a door opener, according to which this protection against jarring by the storage of the lock anchor in; its center of mass is reached.

Aufgabe der Erfindung ist es, die Nachteile des Standes der Technik zumindest zu verringern.The object of the invention is to at least reduce the disadvantages of the prior art.

Diese Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is solved by the subject matter of claim 1. Advantageous developments of the invention are specified in the subclaims.

Erfindungsgemäß ist ein elektrischer Türöffner vorgesehen, also ein Türöffner, der elektrisch betätigt wird. Der Türöffner weist bekanntermaßen eine Schwenkfalle auf, die zwischen Entriegelungsstellung und Verriegelungsstellung schwenkbar gelagert ist. Die Schwenkfalle ist eingerichtet, in Verriegelungsstellung mit einem korrespondierenden Teil eines sich in Schließstellung befindlichen Drehflügels derart in Eingriff gebracht zu werden, dass der Drehflügel an einer Öffnungsbewegung gehindert ist. Im einfachsten Fall handelt es sich bei dem korrespondierenden Teil um die Falle eines Türschlosses. Das Türschloss ist dabei in bekannter Weise am bzw. im hier als Türflügel ausgebildeten Drehflügel montiert. Die Schwenkfalle ist ferner eingerichtet, in Entriegelungsstellung üblicherweise durch ein Öffnen des Drehflügels außer Eingriff mit dem korrespondierenden Teil verschwenkt werden, sodass die Öffnungsbewegung des Drehflügels freigegeben ist. Der Drehflügel kann also geöffnet werden. Der Türöffner verfügt zudem über einen Sperrhebel, der ebenfalls in bekannter Weise um eine erste Achse auf die Schwenkfalle zu in Sperrstellung und von ihr weg in Entsperrstellung schwenkbar gelagert ist. In Sperrstellung verhindert der Sperrhebel ein Schwenken der Schwenkfalle aus der Verriegelungsstellung heraus in Richtung Entriegelungsstellung. Ferner umfasst der Türöffner einen Sperranker, der ebenfalls in bekannter Weise um eine zweite Achse auf den Sperrhebel zu in Blockierstellung und von ihm weg in Freigabestellung schwenkbar gelagert ist. In Blockierstellung verhindert der Sperranker ein Schwenken des Sperrhebels aus der Sperrstellung in Richtung Entsperrstellung. Schließlich weist der Türöffner einen Elektromagneten auf, der eingerichtet ist, bei Betätigung, also bei Bestromung, den Sperranker elektromagnetisch in Richtung Freigabestellung bzw. in eine dazu entgegengesetzte Richtung zu drängen bzw. zu bewegen. Der Türöffner ist so gestaltet, dass der Sperranker daran gehindert ist, in Blockierstellung seine Blockierposition in Bezug auf den sonstigen Türöffner bei einem Weiterverschwenken des Sperrhebels aus der Sperrstellung heraus in Richtung Schwenkfalle und wieder zurück zu verändern. Dadurch könnte ein Rütteln am Türflügel zwar dazu führen, dass der Sperrhebel wiederholt aus seiner Sperrstellung kurzzeitig weiter in Richtung Schwenkfalle und wieder zurück geschwenkt wird. Da sich dies allerdings nicht auf die Position des Sperrankers auswirkt, besteht keine Gefahr, dass der Sperranker aus seiner Blockierstellung heraus sowohl in Richtung Freigabestellung als auch in die dazu entgegengesetzte Richtung "gerüttelt" werden könnte. Damit erhöht sich die Sicherheit im Betrieb des Türöffners, ohne die zum Öffnen des Türflügels erforderliche Energie zu erhöhen.According to the invention, an electric door opener is provided, that is to say a door opener which is electrically actuated. The door opener is known to have a pivotal latch which is pivotally mounted between the unlocked position and the locking position. The pivot latch is adapted to be brought into locking position with a corresponding part of a located in the closed position rotary wing in such a way that the rotary wing is prevented from opening. In the simplest case, the corresponding part is the case of a door lock. The door lock is mounted in a known manner on or in here designed as a door sash. The pivot latch is further configured, are pivoted in unlocking usually by opening the rotary wing out of engagement with the corresponding part, so that the opening movement of the rotary wing is released. The rotary wing can therefore be opened. The door opener also has a locking lever, which is also mounted in a known manner about a first axis on the pivot latch in the locked position and away from it in the unlocked position. In the blocking position, the locking lever prevents the pivoting latch from pivoting out of the locking position toward the unlocking position. Further, the door opener comprises a locking anchor, which is also mounted in a known manner about a second axis on the locking lever in the blocking position and away from it in the release position. In blocking position prevents the Sperranker pivoting of the locking lever from the locked position in the unlocked position. Finally, the door opener on an electromagnet, which is adapted, when actuated, so when energized, the barrier armor electromagnetically in the direction of release position or in an opposite direction to urge or move. The door opener is designed so that the locking lever is prevented in blocking position its blocking position with respect to the other door opener in a further pivoting of the locking lever from the locked position out towards the pivot latch and back again. As a result, a shaking on the door could indeed cause the locking lever is repeatedly repeatedly pivoted from its locked position in the direction of pivoting latch and back again. However, since this does not affect the position of the locking anchor, there is no danger that the locking armor could be "shaken" from its blocking position both in the direction of the release position and in the opposite direction. This increases the safety in the operation of the door opener without increasing the energy required to open the door leaf.

Vorzugsweise erfolgt die vorgenannte Gestaltung des Türöffners in der Weise, dass der Sperranker so gestaltet ist, dass er sich in Blockierstellung außerhalb eines durch das Weiterverschwenken definierten Weiterverschwenkbereichs des Sperrhebels befindet. D. h. der Sperrhebel ist nicht in der Lage, seine Bewegung auf den Sperranker in irgendeiner Art und Weise direkt oder indirekt zu übertragen. Diese Lösung hat den Vorteil, dass keine zusätzlichen Teile erforderlich sind, die Beibehaltung der der Blockierstellung entsprechenden Position des Sperrankers in Bezug auf den sonstigen Türöffner zu gewährleisten.Preferably, the aforementioned design of the door opener is carried out in such a way that the locking armature is designed so that it is in the blocking position outside of a defined by the Weiterverschwenken Weiterverschwenkbereichs the locking lever. Ie. the locking lever is unable to transmit its movement to the locking armor in any way directly or indirectly. This solution has the advantage that no additional parts are required to ensure the retention of the blocking position corresponding position of the locking armature with respect to the other door opener.

Alternativ oder zusätzlich weist der Türöffner als erfindungsgemäße Gestaltung ferner einen Anschlag auf, der ein Verschwenken des Sperrankers in Richtung Blockierstellung begrenzt. Der Anschlag ist dabei so angeordnet, dass er sich außerhalb des gesamten Schwenkbereichs des Sperrhebels befindet. D. h. der Anschlag beeinflusst nicht die Verschwenkbarkeit des Sperrhebels. Bei dieser Gestaltung des Türöffners definiert also der Anschlag und nicht der Sperrhebel die Blockierstellung des Sperrankers bzw. dessen Verschwenkung aus seiner Freigabestellung heraus in Richtung Blockierstellung. Dies ist eine besonders einfache Lösung, die Bewegungen des Sperrankers und des Sperrhebels voneinander zu entkoppeln und dennoch die erfindungsgemäße Wirkung zu erreichen. Konstruktiv aufwendige und kostenintensive Lösungen wie ein anderes Anordnen des Sperrankers und ggf. zusätzliche Rückstellelemente sind nicht erforderlich.Alternatively or additionally, the door opener as a design according to the invention further comprises a stop which limits a pivoting of the locking armature in the blocking position. The stop is arranged so that it is outside the entire pivoting range of the locking lever. Ie. the stop does not affect the pivoting of the locking lever. In this design of the door opener thus defines the stop and not the locking lever, the blocking position of the locking armature or its pivoting from its release position out in the blocking position. This is a particularly simple solution to the movements the locking anchor and the locking lever to decouple each other and still achieve the effect of the invention. Constructively complex and expensive solutions such as another arranging the Sperrankers and possibly additional return elements are not required.

Wiederum alternativ oder zusätzlich kann die vorgenannte Gestaltung des Türöffners derart sein, dass eine dem Sperrhebel zugewandte Fläche des Sperrankers, an der sich der Sperrhebel bei seinem Weiterverschwenken vorbeibewegt, zumindest abschnittsweise einer Umfangslinie eines Kreises folgt, dessen Mittelpunkt ein Punkt auf der ersten Achse ist. Diese erste Achse verläuft dabei senkrecht zu einer durch den Kreis definierten Fläche. Da der Sperrhebel um dieselbe, erste Achse geschwenkt wird, kann es hier allein aufgrund der Gestaltung dieser Fläche des Sperrankers nicht mehr vorkommen, dass der Sperranker vom Sperrhebel bewegt wird.Again alternatively or additionally, the aforementioned design of the door opener be such that a the locking lever facing surface of the locking armature on which the locking lever passes in its Weiterverschwenken, at least partially follows a circumferential line of a circle whose center is a point on the first axis. This first axis runs perpendicular to a surface defined by the circle. Since the locking lever is pivoted about the same, first axis, it can no longer happen here alone due to the design of this surface of the locking armature that the locking armature is moved by the locking lever.

Alternativ oder zusätzlich kann die Gestaltung des Türöffners derart sein, dass die vorgenannte Fläche des Sperrankers so ausgebildet ist, dass der Sperrhebel in Sperrstellung und entlang seiner weitergehenden Verschwenkbarkeit in Richtung Schwenkfalle an dem der Kreislinie folgenden Abschnitt der Fläche des Sperrankers anliegt. D. h. der Sperrhebel dient als Blockierstellungs-Endanschlag des Sperrankers. Der der Kreislinie folgende Abschnitt dieser Fläche verhindert wirksam, dass der Sperranker aus seiner eigentlichen Blockierstellung heraus weiter in Richtung Sperrhebel bewegt werden kann. Diese Lösung erlaubt ein Weglassen des vorgenannten Anschlags. D. h. allein die geometrisch einfache Form dieser Fläche des Sperrankers ermöglicht die erfindungsgemäße Wirkung.Alternatively or additionally, the design of the door opener may be such that the aforementioned surface of the locking armature is formed so that the locking lever rests in the locking position and along its further pivoting in the direction of the pivotal latch on the following section of the circumference of the locking armature. Ie. the locking lever serves as a blocking position end stop of the locking armature. The section of this surface following the circumference effectively prevents the locking armature from being moved out of its actual locking position in the direction of the locking lever. This solution allows omission of the aforementioned attack. Ie. Only the geometrically simple shape of this surface of the locking anchor allows the effect according to the invention.

Wiederum alternativ oder zusätzlich ist der Sperranker in Richtung Blockierstellung vorgespannt gelagert. Dies hat den Vorteil, dass der Sperranker allein aufgrund der auf ihn wirkenden Vorspannung in Richtung Blockierstellung gedrängt wird. Ist die Vorspannung durch eines oder mehrere mechanische Elemente wie Rückstellfedern realisiert, ist keine elektrische Energie erforderlich, den Sperranker in Richtung Blockierstellung zu drängen. Da der Sperranker seine Blockierposition nicht verlassen kann, kann die Vorspannung wie bei bekannten Türöffnern gestaltet sein, die keinen "Rüttelschutz" haben. Sie können zudem, wie später näher erläutert, schwächer ausgebildet werden. D. h. die diese Vorspannung realisierende Vorrichtung kann hinsichtlich der aufzubringenden Vorspannkraft und damit auch hinsichtlich ihrer Abmessungen in gewohnter Manier ausgebildet oder gar verkleinert werden. Dies hat den Vorteil, dass an den sonstigen, im Türöffner angeordneten Teilen weder hinsichtlich ihrer Formen, Abmessungen oder Anordnung im Türöffner Änderungen notwendig sind. Weist der Sperranker den vorgenannten, einer Kreislinie folgenden Abschnitt auf, kann dieser am Sperrhebel anliegen und damit abgestützt sein. Damit wird der Sperranker in bekannter Weise in Richtung Blockierstellung gedrängt, kann diese Position aber nicht verlassen, wenn der Elektromagnet nicht entsprechend aktiviert bzw. deaktiviert wird. Wird der Schwenkhebel verschwenkt, wirkt sich dies aufgrund der kreisförmigen Bogenform besagter Fläche nicht oder nur so geringfügig auf die Position des Sperrankers aus, dass der Sperranker durch das vorgenannte Rütteln, also das dadurch provozierte mehrmalige schnelle Hin- und Herschwenken des Sperrhebels, nicht mehr aufschaukeln kann, sodass der Sperranker irgendwann die Blockierstellung verlässt und so den Sperrhebel freigibt. Diese Lösung erlaubt zudem den Einsatz eines bistabilen Elektromagneten, der nur dann bestromt wird, wenn der Sperranker seine Stellung wechseln soll, und der in der Lage ist, den sich in Freigabe- bzw. Blockierstellung befindlichen Sperranker ohne Bestromung magnetisch entgegen etwaige Vorspannkräfte festzuhalten. Diese Lösung ist besonders energiesparend, sodass der Einsatz von Akkus als Energieversorgung des Türöffners in Frage kommen kann.Again alternatively or additionally, the locking armature is biased towards locking position. This has the advantage that the locking armor is urged in the direction of blocking position solely on account of the prestress acting on it. If the bias is realized by one or more mechanical elements such as return springs, no electrical energy is required to urge the locking armature in the blocking position. Since the locking armor can not leave his blocking position, the bias can be designed as in known door openers that have no "vibration protection". They can also, as explained in more detail later, be made weaker. Ie. the device that realizes this bias can be designed or even reduced in terms of the applied biasing force and thus also in terms of their dimensions in the usual manner. This has the advantage that changes to the other, arranged in the door opener parts are not necessary in terms of their shapes, dimensions or arrangement in the door opener. Does the Sperranker the above, a circle following section, this can rest on the locking lever and thus be supported. Thus, the locking armor is urged in a known manner in the blocking position, but can not leave this position when the solenoid is not activated or deactivated accordingly. If the pivot lever is pivoted, this does not affect the position of the locking armature due to the circular arc shape of said surface or only slightly so that the locking armor no longer wobbles due to the aforementioned shaking, thus provoking repeated rapid back and forth pivoting of the locking lever can, so that the Speranker eventually leaves the blocking position and so releases the locking lever. This solution also allows the use of a bistable electromagnet, which is energized only when the Speranker is to change position, and is able to magnetically located in the release or blocking position Speranker without energization to hold against any pretensioning forces. This solution is particularly energy-saving, so that the use of rechargeable batteries can be considered as energy supply of the door opener.

Im Fall des einer Kreislinie folgenden Abschnitts des Sperrankers und/oder im Fall der vorgespannten Lagerung kann der Sperranker oder der Sperrhebel an einer dem Sperrhebel bzw. dem Sperranker zugewandten Seite, an bzw. mit der sich der Sperrhebel bei seinem Weiterverschwenken vorbeibewegt, einen in Richtung Sperrhebel bzw. Sperranker vorgespannt gelagerten Führungsabschnitt aufweisen. Die Vorspannung ist so groß, dass der Führungsabschnitt entlang des durch das Weiterverschwenken definierten Weiterverschwenkbereichs des Sperrhebels am Sperranker bzw. Sperrhebel anliegt. Die Vorspannung ist zudem so gering, dass der Führungsabschnitt nicht in der Lage ist, den Sperranker vom Sperrhebel weg also in Richtung Freigabestellung zu drängen. Ein Verschwenken des Sperrankers aufgrund des vorgespannt gelagerten Führungsabschnitts in Richtung Freigabestellung ist also verhindert. Diese Lösung hat den Vorteil, dass die vorgenannten Rückstellelemente im Fall des einer Kreislinie folgenden Abschnitts des Sperrankers entfallen können. Ein anderer Vorteil ist, dass im Fall der vorgespannten Lagerung des Sperrankers in Richtung Blockierstellung die vorgenannte Fläche keiner Kreislinie folgen muss. Zudem können Unebenheiten oder andere unerwünschte geometrische Formen in der somit als Lauffläche dienenden Anlagefläche des Sperrankers bzw. Sperrhebels ausgeglichen werden. Abgesehen davon ist es dadurch auch möglich, Ungenauigkeiten in der Positionierung des Sperrankers in Bezug auf den Sperrhebel bis zu einem bestimmten Maß beispielsweise aufgrund unterschiedlichen thermischen Ausdehnungsverhaltens auszugleichen oder ein bestimmtes Abstandsmaß zwischen Sperranker und Sperrhebel zu gewährleisten. Insgesamt verbessert diese Lösung die Sicherheit im Betrieb.In the case of a portion following the circumference of the locking armature and / or in the case of the prestressed bearing, the locking armor or the locking lever can move on a side facing the locking lever or the locking armature, at or with which the locking lever passes when it is pivoted further Have locking lever or Speranker biased mounted guide portion. The bias is so great that the guide portion rests along the defined by the Weiterverschwenken Weiterverschwenkbereichs the locking lever on Speranker or locking lever. The bias is also so low that the guide portion is not able to push the locking armature away from the locking lever so towards release position. A pivoting of the locking armature due to the prestressed bearing guide section in the direction of the release position is thus prevented. This solution has the advantage that the aforementioned restoring elements can be dispensed with in the case of the section of the locking armature following a circular line. Another advantage is that in the case of biased storage of the locking anchor in the direction of blocking position, the aforementioned surface must follow no circular line. In addition, bumps or other undesirable geometric shapes in the thus serving as a running surface bearing surface of the locking lever or locking lever can be compensated. Apart from that, it is also possible to compensate for inaccuracies in the positioning of the locking armature with respect to the locking lever to a certain extent, for example, due to different thermal expansion behavior or to ensure a certain distance between the locking armature and locking lever. Overall, this solution improves safety during operation.

Eine erfindungsgemäße Türanlage umfasst einen Drehtürflügel als vorgenannten Drehflügel. Ferner umfasst sie ein am oder im Drehtürflügel angebrachtes Türschloss mit einer Schlossfalle als vorgenanntes korrespondierendes Teil. Schließlich umfasst die Türanlage einen der vorgenannten Türöffner. D. h. Türöffner und Türschloss sind in Schließstellung des Drehtürflügels so zueinander angeordnet, dass die Schwenkfalle in Verriegelungsstellung über die Schlossfalle den Drehtürflügel an einem Öffnen hindert.A door system according to the invention comprises a revolving door wing as the aforementioned rotary wing. Furthermore, it comprises a door lock mounted on or in the revolving door leaf with a latch as the aforementioned corresponding part. Finally, the door system includes one of the aforementioned door opener. Ie. Door opener and door lock are arranged in the closed position of the revolving door wing to each other so that the pivot latch in the locked position on the latch prevents the revolving door from opening.

Figur 1 zeigt einen elektrischen Türöffner 1 gemäß einer ersten Ausführungsform der Erfindung, und zwar nur die zur Erklärung der Erfindung wesentlichen Teile. Es ist klar, dass weitere Teile wie Stromanschluss, Busanschluss, Steuerung, Gehäusedeckel usw. vorgesehen sein können, um den Türöffner 1 in der gewünschten Weise betreiben zu können. FIG. 1 shows an electric door opener 1 according to a first embodiment of the invention, and only the essential parts for explaining the invention. It is clear that further parts such as power supply, bus connection, control, housing cover, etc. may be provided to operate the door opener 1 in the desired manner.

Der Türöffner 1 ist im Wesentlichen wie jeder bekannte elektrische Türöffner aufgebaut. D. h. er weist ein Gehäuse 10 auf, in dem im Wesentlichen alle Komponenten des Türöffners 1 angeordnet sind. Dazu gehört eine Schwenkfalle 20, die um eine nicht bezeichnete, parallel zur Längserstreckung der Schwenkfalle 20 verlaufende Achse schwenkbar angeordnet ist.The door opener 1 is basically constructed like any known electric door opener. Ie. it has a housing 10 in which substantially all components of the door opener 1 are arranged. This includes one Pivot trap 20 which is pivotally mounted about an unspecified, parallel to the longitudinal extent of the pivotal latch 20 extending axis.

Die Schwenkfalle 20 weist an einer einem Sperrhebel 30 abgewandten Seite einen Verriegelungsabschnitt 21 in Form eines Fallenwinkels auf. In einem zwischen dem Fallenwinkel und einer Rückwand 11 gebildeten Aufnahmeraum 5 ist beispielsweise eine Falle eines korrespondierenden Schlosses aufgenommen. Die Falle kommt in Schließstellung des Drehflügels mit ihrer in Öffnungsrichtung eines dazugehörigen Drehflügels weisenden Fläche an der in Richtung Rückwand 11 weisenden Fläche des Fallenwinkels zu liegen. Die Schwenkfalle 20 ist vorzugsweise in diese Stellung in ebenfalls bekannter Weise vorgespannt gelagert. Beim Öffnen des Drehflügels wird die Schwenkfalle 20, wenn nicht gesperrt, in Öffnungsrichtung, hier also zur Vorderseite des ohne Abdeckung dargestellten Türöffners 1 hin, soweit verschwenkt, dass die Falle an der Schwenkfalle 20 vorbei bewegt werden kann. Die Schwenkfalle 20 weist an ihrer vom Verriegelungsabschnitt 21 weg weisenden Seite einen Vorsprung als Sperrabschnitt 22 auf, der mit einem Sperrabschnitt 31 des Sperrhebels 30 in ebenfalls bekannter Weise zusammenwirkt.The pivot latch 20 has on a side facing away from a locking lever 30 a locking portion 21 in the form of a latch angle. In a receiving space 5 formed between the trap angle and a rear wall 11, for example, a trap of a corresponding lock is received. The trap comes to lie in the closed position of the rotary wing with its pointing in the opening direction of a corresponding rotary wing surface on the facing back wall 11 surface of the trap angle. The pivoting latch 20 is preferably biased in this position in a likewise known manner. When opening the rotary wing, the pivot latch 20, if not locked, in the opening direction, so here to the front of the door opener 1 without cover shown, pivoted so far that the case can be moved past the pivot latch 20. The pivot latch 20 has on its side facing away from the locking portion 21 side a projection as a locking portion 22 which cooperates with a locking portion 31 of the locking lever 30 in a likewise known manner.

Der Sperrabschnitt 31 ist mittels einer sich in Richtung Schwenkfalle 20 und der Rückwand 11 des Gehäuses 10 erstreckenden Fläche gebildet. Diese Fläche verläuft also schräg zur Rückwand 11. Die Schwenkfalle 20 wird daher bei mechanischer Beaufschlagung durch die vorgenannte Falle in die vorgenannte Öffnungsrichtung mit ihrem Sperrabschnitt 22 gegen den Sperrabschnitt 31 gedrückt. Ist der Sperrhebel 30 nicht blockiert, kann die Schwenkfalle 20 über ihren Sperrabschnitt 22 den Sperrhebel 30 über das Gleiten entlang der schrägen Fläche des Sperrabschnitts 31 von sich weg drücken. Dadurch wird der Sperrabschnitt 22 am Sperrabschnitt 31 vorbei bewegt, und die Schwenkfalle 20 kann die Falle freigeben, sodass der zugehörige Drehflügel geöffnet werden kann. Der Sperrhebel 30 ist im Gehäuse 10 über eine in einem Lagerbock 12 des Gehäuses 10 angeordnete bzw. daran angeformte Schwenkachse 34 frei rotierbar bzw. schwenkbar aufgenommen. Beispielhaft verhindert ein Sprengring 2, dass sich der Sperrhebel 30 von der Schwenkachse 34 lösen kann. Der Sperrhebel 30 ist mittels einer Rückstellfeder 3 in Richtung Sperrstellung vorgespannt gelagert. Ein der Schwenkachse 34 abgewandtes, freies Ende des Sperrhebels 30 bildet einen Blockierabschnitt 32, der in bekannter Weise mit einem korrespondierenden Blockierabschnitt 41 eines Sperrankers 40 zusammenwirkt.The blocking section 31 is formed by means of a surface extending in the direction of the pivoting catch 20 and the rear wall 11 of the housing 10. Thus, this area extends obliquely to the rear wall 11. The pivotal latch 20 is therefore pressed against the locking portion 31 with its locking portion 22 in the aforementioned case in the aforementioned case with mechanical loading by the aforementioned case. If the locking lever 30 is not blocked, the pivoting latch 20 can push the locking lever 30 over its locking portion 22 by sliding along the inclined surface of the locking portion 31 away. Thereby, the locking portion 22 is moved past the locking portion 31, and the pivot latch 20 can release the case, so the associated rotary wing can be opened. The locking lever 30 is freely rotatably or pivotably received in the housing 10 via a pivot axis 34 arranged in a bearing block 12 of the housing 10 or formed thereon. By way of example, a snap ring 2 prevents the locking lever 30 from being able to detach from the pivot axis 34. The locking lever 30 is biased by a return spring 3 in the direction of locking position. A free end of the locking lever 30 facing away from the pivot axis 34 forms a blocking section 32 which cooperates in a known manner with a corresponding blocking section 41 of a locking armature 40.

Der Sperranker 40 ist im Gehäuse 10 über eine am Gehäuse 10 angeordnete bzw. daran angeformte Schwenkachse 44 frei rotierbar bzw. schwenkbar aufgenommen. Beispielhaft verhindert wiederum ein Sprengring 2, dass sich der Sperranker 40 von der Schwenkachse 44 lösen kann.The locking armature 40 is freely rotatable or pivotably received in the housing 10 via a pivot axis 44 arranged on the housing 10 or formed thereon. By way of example, a snap ring 2 again prevents the locking armature 40 from becoming detached from the pivot axis 44.

Der Blockierabschnitt 41 ist mittels eines in Richtung Sperrhebel 30 weisenden Vorsprungs gebildet. Der Sperranker 40 ist in Blockierstellung gezeigt und bewirkt, dass der Sperrhebel 30 nur so weit in Richtung Blockierabschnitt 41 geschwenkt werden kann, bis die Blockierabschnitte 32, 41 aneinander anliegen. In dieser Stellung liegt der Sperrabschnitt 22 der Schwenkfalle 20, in Verschwenkrichtung zum Öffnen des vorgenannten Drehflügels gesehen, auf dem Sperrabschnitt 31 des Sperrhebels 30. Der Sperranker 40 ist mittels hier zweier Rückstellfedern 4 in Richtung Blockierstellung vorgespannt gelagert. Die Rückstellfedern 4 drücken gegen eine zugewandte Seite bzw. Fläche 43 des Sperrankers 40.The blocking portion 41 is formed by means of a direction of locking lever 30 facing projection. The locking arm 40 is shown in blocking position and causes the locking lever 30 can only be pivoted so far in the direction blocking portion 41 until the blocking portions 32, 41 abut each other. In this position, the locking portion 22 of the pivotal latch 20, seen in the pivoting direction for opening the aforementioned rotary wing, on the locking portion 31 of the locking lever 30. The locking armature 40 is biased by means of two return springs 4 toward blocking position. The return springs 4 press against a facing side or surface 43 of the locking armature 40th

Da der Sperrhebel 30 aufgrund des Sperrankers 40 nicht von der Schwenkfalle 20 weiter weg geschwenkt werden kann, ist die Schwenkfalle 20 nicht in der Lage, am Sperrabschnitt 31 vorbei zu schwenken, ist also in ihrer Schwenkbewegung gesperrt. Schwenkfalle 20 und Sperrhebel 30 befinden sich also in Sperrstellung. Damit können bei geschlossenem Drehflügel die Falle nicht an der Schwenkfalle 20 vorbei bewegt und damit der Drehflügel nicht geöffnet werden. Da der Drehflügel also in der Schließstellung verriegelt ist, befindet sich die Schwenkfalle 20 in Verriegelungsstellung.Since the locking lever 30 can not be pivoted further away from the pivoting latch 20 due to the locking armature 40, the pivoting latch 20 is unable to pivot past the locking portion 31 so locked in their pivotal movement. Pivot trap 20 and locking lever 30 are thus in the locked position. Thus, the case can not be moved past the pivot latch 20 with closed rotary wing and thus the rotary wing not be opened. Since the rotary wing is thus locked in the closed position, the pivot latch 20 is in the locked position.

Würde nun am Drehflügel gerüttelt, übertrüge sich dies auf die Schwenkfalle 20, die aufgrund der momentanen Wirkverbindung zwischen Falle und Verriegelungsabschnitt 21 in gewissem Maß hin und her schwenken würde. Da zugleich beide Sperrabschnitte 22, 31 aneinander anliegen, würde dies dazu führen, dass der Sperrhebel 30 einmalig oder wiederholt zur Schwenkfalle 20 hin und wieder von ihr weg geschwenkt würde. Dies führt dazu, dass die Blockierabschnitte 32, 41 wiederholt voneinander weg und wieder aufeinander zu bewegt würden. Erfolgt das Rütteln genügend schnell, könnte dies in Verbindung mit den am Türöffner 1 auftretenden Erschütterungen dazu führen, dass der Sperranker 40 sofort bzw. nach und nach in Richtung Freigabestellung bewegt wird.If now shaken on the rotary wing, this would transfer to the pivotal latch 20, which would swing to some extent due to the current operative connection between the latch and locking portion 21 back and forth. Since at the same time both barrier portions 22, 31 abut each other, this would cause the locking lever 30 would be pivoted once or repeatedly to the pivotal latch 20 now and then away from her. As a result, the blocking portions 32, 41 are repeatedly moved away from each other and back to each other. If the shaking sufficiently fast, this could in conjunction with the vibrations occurring at the door opener 1 cause the locking armature 40 is moved immediately or gradually towards the release position.

Ist der Türöffner 1 bei einer mit Dichtungen versehenen Türanlage wie einer Rauchschutztüranlage eingesetzt, liegen die Blockierabschnitte 32, 41 in Blockierstellung aneinander an. Die Dichtungen setzen den jeweils zugehörigen Türflügel in Schließstellung derart unter Vorspannung bzw. in eine derartige Stellung, dass die vorgenannte Falle die Schwenkfalle 20 des korrespondierenden Türöffners 1 in Öffnungsrichtung drängt. Würde der Türöffner 1 bei Türanlagen ohne derartige Dichtungen eingesetzt, entfiele diese Art von Vorspannung.If the door opener 1 is used in a door system provided with seals, such as a smoke protection door system, the blocking sections 32, 41 abut one another in the blocking position. The seals put the respectively associated door in the closed position under bias or in such a position that the aforementioned case urges the pivotal latch 20 of the corresponding door opener 1 in the opening direction. If the door opener 1 used in door systems without such seals, would account for this type of bias.

Damit der Türöffner 1 bei beiden Arten von Türanlagen eingesetzt werden kann, ist beim Türöffner 1 für Türanlagen ohne derartige Dichtungen ein Spiel beim Sperrhebel 30 in der vorgenannten Blockierstellung vorgesehen. D. h. der Sperrhebel 30 kann bei verriegelnder Schwenkfalle 20 und blockierendem Sperranker 40 in gewissem Maß zwischen Schwenkfalle 20 und Blockierabschnitt 41 des Sperrankers 40 verschwenkt werden. D. h. die Blockierabschnitte 32, 41 liegen, wie in Figur 1a gezeigt, in Blockierstellung nicht zwangsläufig aneinander an. Dadurch ist das vorgenannte Rütteln an der Schwenkfalle 20 insbesondere bei dieser Art von Türanlagen möglich. Ein anderer Grund für dieses Spiel liegt darin begründet, dass die Blockierabschnitte 32, 41 bei einem gewollten Verschwenken des Sperrankers 40 sonst nicht ohne weiteres aneinander vorbeibewegt werden könnten. Nicht zuletzt können dadurch bauartbedingte Toleranzen ausgeglichen werden.Thus, the door opener 1 can be used in both types of door systems, is at the door opener 1 for door systems without such seals a Play the locking lever 30 provided in the aforementioned blocking position. Ie. the locking lever 30 can be pivoted to a certain extent between the pivotal latch 20 and blocking portion 41 of the locking armature 40 when locking the pivoting latch 20 and blocking locking armature 40. Ie. the blocking portions 32, 41 are located as in FIG FIG. 1a shown in blocking position not necessarily to each other. As a result, the aforementioned shaking on the pivot latch 20 in particular in this type of door systems is possible. Another reason for this game is due to the fact that the blocking sections 32, 41 otherwise would not easily be able to move past one another in the event of intentional pivoting of the locking armature 40. Last but not least, design-related tolerances can be compensated.

Um das Bewegen des Sperrankers 40 in Richtung Freigabestellung aufgrund des vorgenannten Rüttelns zu verhindern, ist der Sperranker 40 speziell ausgebildet. Wie in Figur 1b gezeigt, ist eine Fläche 42, entlang der der Blockierabschnitt 32 des Sperrhebels 30 beim Rütteln bewegt wird, nicht eben sondern gekrümmt ausgebildet. Die Krümmung entspricht einer Umfangslinie eines Kreises, dessen Radius r (gekennzeichnet durch den mit Strichpunktlinie versehenen Doppelpfeil) im Wesentlichen dem Abstand des weitesten von einem Mittelpunkt M der Schwenkachse 34 entfernten Punkt des Sperrhebels 30 oder ist geringfügig größer. Beim durch Rütteln verursachten Verschwenken des Sperrhebels 30 folgt dieser Punkt des Sperrhebels 30 einer Umfangslinie eines Kreises mit dem Radius r. Da der Sperranker 40 von den Rückstellfedern 4 gegen diesen Punkt gedrückt wird, kann der Sperranker 40 aufgrund der beschriebenen gekrümmten Form der Fläche 42 seine Position in Richtung Sperrhebel 30 bzw. in Richtung zugehörige Rückstellfedern 4 nicht verändern. D. h. das Rütteln, auch wenn wiederholt, kann zu keinem oder nur zu so einem geringfügigen Verschwenken des Sperrankers 40 führen, dass dieser sich nicht aufschaukeln kann und somit die Blockierung des Sperrhebels 30 durch den Sperranker 40 sicher nicht aufgehoben wird.In order to prevent the movement of the locking armature 40 in the direction of the release position due to the aforementioned shaking, the locking armature 40 is specially designed. As in FIG. 1b is shown, a surface 42 along which the blocking portion 32 of the locking lever 30 is moved when jogging, not flat but curved. The curvature corresponds to a perimeter of a circle whose radius r (indicated by the dotted-dashed double arrow) is substantially the distance of the farthest point of the locking lever 30 remote from a center M of the pivot axis 34 or is slightly larger. When caused by joggling pivoting of the locking lever 30 follows this point of the locking lever 30 a circumferential line of a circle with the radius r. Because the locking arm 40 is pressed against this point by the return springs 4, the locking armature 40 can not change its position in the direction of the locking lever 30 or in the direction of associated return springs 4 due to the described curved shape of the surface 42. Ie. the shaking, even if repeated, can lead to no or only such a slight pivoting of the Sperrankers 40 that this can not aufschaukeln and thus the blocking of the locking lever 30 by the Sperranker 40 is certainly not repealed.

Ferner ist in Figur 1b ein Elektromagnet 50 erkennbar, der über einen Stößel 51 in der Lage ist, den Sperranker 40 aus der Blockierstellung gegen die Wirkung der Rückstellfedern 4 in Richtung Freigabestellung zu schwenken. In der Freigabestellung kann nun der Sperrhebel 30 am Blockierabschnitt 41 vorbei von der Schwenkfalle 20 weg in Richtung Entsperrstellung geschwenkt werden.Furthermore, in FIG. 1b a solenoid 50 can be seen, which is about a plunger 51 in a position to pivot the locking armature 40 from the blocking position against the action of the return springs 4 in the direction of the release position. In the release position, the blocking lever 30 can now be pivoted away from the blocking latch 41, away from the pivoting latch 20, in the unlocking position.

Figur 1c zeigt den Türöffner 1 von Figur 1b in vergrößertem Ausschnitt. Es ist deutlich zu erkennen, dass der Vorsprung 33 eine abgerundete Spitze aufweist, mit der der Sperrhebel 30 bei einer Verschwenkung aus der gezeigten Blockierstellung nach links, also in Richtung Schwenkfalle 20, entlang der Fläche 42 des Sperrankers 40 entlangläuft. Die Abrundung dient der Verringerung der entstehenden Reibung und der Verminderung der Gefahr eines Verkantens. Figure 1c shows the door opener 1 of FIG. 1b in enlarged section. It can be clearly seen that the projection 33 has a rounded tip with which the locking lever 30 during pivoting from the blocking position shown to the left, ie in the direction of the pivot latch 20, along the surface 42 of the locking armature 40 along. The rounding serves to reduce the resulting friction and reduce the risk of tilting.

Figur 2 zeigt einen Türöffner 1 gemäß einer zweiten Ausführungsform der Erfindung und in vergrößertem Ausschnitt sowie ohne Verriegelungsabschnitt 21. Diese Ausführungsform unterscheidet sich von der ersten Ausführungsform hauptsächlich in der Gestaltung und Anordnung des Sperrankers 40. FIG. 2 shows a door opener 1 according to a second embodiment of the invention and in enlarged detail and without locking portion 21. This embodiment differs from the first embodiment mainly in the design and arrangement of the locking anchor 40th

Wie zu erkennen, ist die Fläche 42 exemplarisch nicht bogenförmig ausgebildet. Vielmehr bildet sie den Boden einer bereits aus herkömmlichen Türöffnern 1 bekannten Ausnehmung 45. D. h. die Fläche 42 ist so ausgebildet, dass der Sperranker 40 im Fall des vorbeschriebenen schnellen Hin- und Herschwenkens des Sperrhebels 30 in Richtung Schwenkfalle 20 in Richtung Sperrhebel 30 gedrückt und beim Zurückschwenken des Sperrhebels 30 zurück in Richtung Blockierstellung etwas weiter in Richtung Federn 4 gedrückt wird. Durch das Rütteln, also durch das dadurch provozierte mehrmalige schnelle Hin- und Herschwenken des Sperrhebels 30, kann sich der Sperranker 40 so aufschaukeln, dass er sich aus seiner Blockierstellung in Richtung Freigabestellung weg bewegt und damit der Sperrhebel 30 freigegeben wird.As can be seen, the surface 42 is exemplarily not arcuate. Rather, it forms the bottom of a well known from conventional door openers 1 recess 45th D. h. the surface 42 is formed so that the locking armature 40 is pressed in the case of the above fast swinging back and forth of the locking lever 30 in the direction of the pivotal latch 20 in the direction of locking lever 30 and the pivoting back of the Locking lever 30 is pushed back towards the blocking position slightly further towards springs 4. By shaking, so provoked by the repeated quick swinging back and forth of the locking lever 30, the locking arm 40 can rock so that it moves away from its blocking position in the direction of the release position and thus the locking lever 30 is released.

Um dies zu vermeiden, ist ein im Gehäuse 10 ortsfest angeordneter Anschlag 13 vorgesehen, der das Schwenken des Sperrankers 40 in Richtung Sperrhebel 30 begrenzt. D. h. der Anschlag 13 definiert die Blockierstellung des Sperrankers 40.To avoid this, a fixedly arranged in the housing 10 stop 13 is provided which limits the pivoting of the locking armature 40 in the direction of locking lever 30. Ie. the stop 13 defines the blocking position of the locking anchor 40.

Der Anschlag 13 ist dabei so angeordnet, dass der Sperrhebel 30 weder in der in Figur 2 dargestellten Blockierstellung noch in einer anderen Stellung, in der der Sperrhebel 30 noch weiter in Richtung Schwenkfalle 20 geschwenkt ist, in der Lage ist, von sich aus den Sperranker 40 vom Anschlag 13 in Richtung Federn 4 abzuheben. Entweder stellt der Anschlag 13 sicher, dass die Fläche 42 immer einen Abstand zum Sperrhebel 30 aufweist oder maximal vom Sperrhebel 30 berührt werden kann. D. h. auch bei dieser Ausführung ist das vorgenannte Aufschaukeln unterbunden.The stop 13 is arranged so that the locking lever 30 neither in the in FIG. 2 Blocking position shown still in another position in which the locking lever 30 is further pivoted in the direction of the pivotal latch 20, is able to stand out from the barrier armature 40 from the stop 13 in the direction of springs 4. Either the stop 13 ensures that the surface 42 always has a distance from the locking lever 30 or can be touched by the locking lever 30 at most. Ie. also in this embodiment, the aforementioned rocking is prevented.

Der Anschlag 13 kann an der Gehäuse-Rückwand 11 angeformt oder an ihr beispielsweise mittels einer in die Rückwand 11 eingeschraubten Schraube gebildet sein.The stop 13 may be formed on the housing rear wall 11 or formed on it, for example by means of a screwed into the rear wall 11 screw.

Figur 3a zeigt einen Türöffner 1 gemäß einer dritten Ausführungsform der Erfindung ebenfalls ohne Verriegelungsabschnitt 21. Hier fehlt der Anschlag 13 exemplarisch wieder. Die Fläche 42 folgt beispielhaft der vorgenannten Umfangslinie eines Kreises mit Radius r, der hier etwas größer ist als der Abstand des hier nicht dargestellten Schenkmittelpunkts M des Sperrhebels 30 vom am weitesten davon entfernten Punkt des Sperrhebels 30. FIG. 3a shows a door opener 1 according to a third embodiment of the invention also without locking portion 21. Here, the stop 13 is missing again by way of example. The surface 42 follows by way of example the aforementioned circumferential line of a circle with radius r, which is slightly larger here as the distance of the Schenkmittelpunkts M not shown here of the locking lever 30 from the farthest point of the locking lever 30th

An einer dem Sperranker 40 zugewandten Seite des Blockierabschnitts 41 weist der Sperranker 30 einen Führungsabschnitt 60 auf. Dieser umfasst eine in Richtung Sperranker 40 vorgespannt gelagerte Rolle 61. Die Vorspannung ist derart, dass die Rolle 61 zwar gegen den Sperranker 40 gedrängt wird, aber nicht in der Lage ist, diesen vom Schwenkhebel 30 weg in Richtung Freigabestellung zu bewegen. Die Rolle 61 wird also mit einer Kraft gegen den Sperranker 40 gedrückt, die sicherstellt, dass sich der Abstand zwischen Sperranker 40 und Sperrhebel 30 nicht oder nur so geringfügig ändert, dass das vorgenannte Aufschaukeln nicht auftreten kann.On a side of the blocking section 41 facing the locking armature 40, the locking armature 30 has a guide section 60. This comprises a biased towards Sperranker 40 mounted roller 61. The bias is such that the roller 61 is indeed urged against the locking armature 40, but is not able to move it away from the pivot lever 30 in the direction of release position. The roller 61 is thus pressed with a force against the Sperranker 40, which ensures that the distance between Speranker 40 and locking lever 30 is not or only slightly so that the aforementioned rocking can not occur.

Die Rolle 61 ist über eine Achse 62 bzw. Welle in einem korrespondierenden Langloch 35 des Sperrhebels 30 translatorisch geführt aufgenommen. Das Langloch 35 erstreckt sich vorzugsweise entlang einer Linie, die sowohl den Schenkmittelpunkt M des Sperrhebels 30 als auch die Fläche 42 des Sperrankers 40 schneidet. D. h. die Linie entspricht der Radiusstrecke hinsichtlich der Fläche 42.The roller 61 is received translationally guided via an axis 62 or shaft in a corresponding slot 35 of the locking lever 30. The elongated hole 35 preferably extends along a line which intersects both the Schenk center M of the locking lever 30 and the surface 42 of the locking armature 40. Ie. the line corresponds to the radius distance with respect to the surface 42.

Wie ferner zu erkennen, fehlen hier exemplarisch die Federn 4. Dies ist möglich, wenn der Türöffner 1 in der gezeigten Stellung eingebaut wird. Die Gewichtskraft des Sperrankers 40 reicht aus, die Blockierstellung einzunehmen.As can further be seen, the springs 4 are omitted here by way of example. This is possible when the door opener 1 is installed in the position shown. The weight of the Sperranker 40 is sufficient to take the blocking position.

Figur 3b zeigt den Sperrhebel 30 bzw. dessen Blockierabschnitt 32 im Schnitt und im Wesentlichen von links in Figur 3a. Wie zu erkennen, ist im Bereich des Blockierabschnitts 32 eine nicht durchgehende, in Richtung des hier nicht dargestellten Sperrankers 40 offene Ausnehmung 36 ausgebildet. In die Ausnehmung 36 ist ein Vorspannelement in Form einer Feder 65 eingesetzt. An ihrer dem Sperranker 40 zugewandten Ende ist ein exemplarisch im Querschnitt U-förmiger Halter 64 mit seinem Boden abgestützt und ebenfalls in der Ausnehmung 36 aufgenommen. Die Achse 62 bzw. Welle ist fest bzw. frei rotierbar in den freien Schenkeln des Halters 64 aufgenommen und steht mit beiden Enden aus dem Halter 64 bzw. aus dem jeweiligen freien Schenkel des Halters 64 nach außen vor. Die Achs- bzw. Wellenenden sind in einem jeweiligen von zwei beidseitig der Ausnehmung 36 ausgebildeten Langlöchern 35 des Sperrhebels 30 entlang deren Längserstreckung translatorisch geführt aufgenommen. D. h. beide Langlöcher 35 erstrecken sich in dieselbe Richtung. Im durch den Halter 64 gebildeten Aufnahmeraum ist die Rolle 61 frei rotierbar aufgenommen. Sie ist dabei frei rotierbar oder drehfest auf der Achse 62 bzw. Welle angeordnet. Damit die Rolle 61 nicht an den freien Schenkeln des Halters 64 reiben kann, ist zwischen der Rolle 61 und dem jeweiligen freien Schenkel ein jeweiliger Abstandhalter 63 angeordnet. Die Feder 65 bewirkt somit die vorgenannte Vorspannung der Rolle 61 in Richtung Sperranker 40. FIG. 3b shows the locking lever 30 and its blocking portion 32 in section and substantially from the left in FIG. 3a , As can be seen, in the region of the blocking section 32, a non-continuous recess 36, which is open in the direction of the locking armature 40, which is not shown here, is formed. In the recess 36, a biasing element in the form of a spring 65 is inserted. At its end facing the barrier arm 40, an example of a U-shaped cross-section holder 64 is supported with its bottom and also received in the recess 36. The shaft 62 or shaft is fixed or freely rotatably received in the free legs of the holder 64 and protrudes with both ends of the holder 64 and from the respective free leg of the holder 64 to the outside. The axle or shaft ends are received translationally guided in a respective of two formed on both sides of the recess 36 oblong holes 35 of the locking lever 30 along its longitudinal extent. Ie. Both slots 35 extend in the same direction. In the receiving space formed by the holder 64, the roller 61 is received freely rotatable. It is freely rotatable or rotationally fixed on the shaft 62 or shaft arranged. Thus, the roller 61 can not rub against the free legs of the holder 64, a respective spacer 63 is disposed between the roller 61 and the respective free leg. The spring 65 thus causes the aforementioned bias of the roller 61 in the direction barrier arm 40th

Die Erfindung ist nicht auf die vorbeschriebenen Ausführungsformen beschränkt. Um das Aufschaukeln des Sperrankers 40 zu erschweren oder zu verhindern, kann als alternatives oder zusätzliches Rückstellelement eine magnetische Wirkverbindung zwischen Sperranker 40 und Sperrhebel 30 vorgesehen sein. D. h. einer der Blockierabschnitte 32, 43 bzw. eine der einander zugewandten Bereiche bzw. Flächen (wie die Fläche 42) sind aus magnetisierbarem Material gebildet oder weisen ein solches auf. Der andere, also korrespondierende Blockierabschnitt 43, 32 oder der bzw. die andere zugewandte Bereich bzw. Fläche ist dementsprechend aus dauermagnetischem Material gebildet oder weist ein solches auf. Dadurch ist es dem Sperrhebel 30 möglich, den Sperranker 40 sicher in Richtung Blockierstellung zu ziehen, was das vorgenannte Aufschaukeln des Sperrankers 40 zumindest erschwert.The invention is not limited to the above-described embodiments. To complicate the rocking of the locking armature 40 or prevent, can be provided as an alternative or additional return element, a magnetic operative connection between locking armature 40 and locking lever 30. Ie. one of the blocking sections 32, 43 or one of the mutually facing areas or surfaces (such as the surface 42) are formed from magnetizable material or have such. The other, thus corresponding blocking portion 43, 32 or the other or the other facing area or surface is accordingly formed from permanent magnetic material or has such. This makes it possible for the locking lever 30, the locking armature 40 safely in Toward the blocking position, which makes the aforementioned rocking of the barrier anchor 40 at least difficult.

Der Anschlag 13 kann bei allen Ausführungsformen vorgesehen sein.The stop 13 may be provided in all embodiments.

Ferner kann der Anschlag 13 so angeordnet sein, dass er sich außerhalb des gesamten Verschwenkbereichs des Sperrhebels 30 befindet, also dessen Verschwenkung nirgends beeinflussen kann. Alternativ kann der Anschlag 13 zugleich einen Endanschlag für den Sperrhebel 30 beispielsweise für dessen Entsperrstellung darstellen.Furthermore, the stop 13 may be arranged so that it is outside the entire pivoting range of the locking lever 30, so its pivoting can affect anywhere. Alternatively, the stop 13 at the same time represent an end stop for the locking lever 30, for example, for its unlocked position.

Auch der Führungsabschnitt 60 kann bei allen Ausführungsformen Verwendung finden.The guide section 60 can also be used in all embodiments.

Der Führungsabschnitt 60 ist nicht auf eine Rolle beschränkt. Beispielsweise kann ein fester oder elastischer Gleitbelag vorgesehen sein, um Sperranker 40 und Sperrhebel 30 aneinander entlang zu führen. Es ist mithin jede Art von Führungsabschnitt möglich, der die Position des Sperrankers 40 so sichert, dass das vorgenannte Aufschaukeln des Sperrankers 40 verhindert ist.The guide portion 60 is not limited to a roll. For example, a solid or resilient sliding coating may be provided to guide locking arm 40 and locking lever 30 along each other. Consequently, any type of guide section is possible which secures the position of the locking armature 40 in such a way that the aforementioned rocking of the locking armature 40 is prevented.

Aus den vorhergehenden Erläuterungen wird klar, dass die vorbeschriebenen Rückstellelemente zum Zwecke der vorgespannten Lagerung des Sperranker 40 beispielsweise in Form der angegebenen Federn 4 nur noch dafür zuständig sein müssen, den Sperranker 40 gegebenenfalls entgegen der Wirkung des Elektromagneten 50, wenn nicht bestromt bzw. bestromt, sicher in die Blockierstellung zu bringen. Dies ist beispielsweise bei Feuerschutztüren erforderlich, die ohne Bestromung Türflügel verriegeln können müssen. Zudem kann es sein, dass diese Rückstellelemente auch dafür zuständig sein müssen, den Sperranker 40 entgegen der Gewichtskraft des Sperrankers 40 zu bewegen. Dies ist erforderlich, wenn der Türöffner 1 in Bezug auf die Figuren auf den Kopf gestellt ist. Da die Rückstellelemente aber nicht mehr dafür zuständig sein müssen, den Sperranker 40 sicher gegen den Sperrhebel 30 zu drücken, um vorgenanntes Aufschaukeln zu verhindern oder zu erschweren, kann die von diesen Rückstellelementen erzeugte Vorspannung gegenüber dem Stand der Technik geringer ausfallen. Im Fall der Federn 4 können diese dadurch kleiner ausfallen, was Kostenvorteile mit sich bringt. Damit einhergehend muss der Elektromagnet 50 ebenfalls eine gegenüber dem Stand der Technik geringere Kraft (gegen die Vorspannung) aufbringen, wodurch auch dieser verkleinert werden kann. Dies ermöglicht, den Türöffner 1 insgesamt kleiner zu bauen oder die in dessen Gehäuse 10 anzuordnenden Komponenten anders oder gar mehr Komponenten im Gehäuse 10 unterzubringen.From the preceding explanations it is clear that the above-described restoring elements for the purpose of prestressed storage of Speranker 40, for example in the form of the specified springs 4 only have to be responsible for the locking armature 40, if necessary against the action of the electromagnet 50, if not energized or energized to bring safely into the blocking position. This is necessary, for example, in the case of fire doors, which must be able to lock doors without energizing them. In addition, it may be that these reset elements must also be responsible for the locking armature 40 against the weight of the locking anchor 40 to move. This is necessary when the door opener 1 is turned upside down with respect to the figures. But since the reset elements no longer have to be responsible for securely pushing the locking armature 40 against the locking lever 30 in order to prevent or aggravate the aforementioned rocking, the pretensioning produced by these restoring elements can be lower than in the prior art. In the case of the springs 4, these can thereby be smaller, which brings cost advantages. Along with this, the electromagnet 50 must also apply a lower force (compared to the prestressing) compared to the prior art, as a result of which this too can be reduced. This makes it possible to make the door opener 1 smaller overall or to accommodate the components to be arranged in its housing 10 differently or even more components in the housing 10.

Auch wenn erfindungsgemäß hauptsächlich vorgesehen ist, mit dem Türöffner 1 Türschlossfallen zu verriegeln, kann vorgesehen sein, den Drehflügel beispielsweise mit einer Ausnehmung auszustatten, in die der Türöffner 1 mit seinem Verriegelungsabschnitt 22 verriegelnd eingreift. Diese somit Verriegelungsausnehmung könnte an einem zweiten Drehflügel oder einem in Bezug auf die gesamte Türanlage ortsfesten Element wie einer Türzarge ausgebildet bzw. angeordnet sein. Dies ist beispielsweise für Karusselltüren eine geeignete Lösung. Bei dieser Art von Verriegelung könnte der Türöffner 1 bei entsprechender Montage auch bei Schiebeflügeln eingesetzt werden.Even if the invention is mainly intended to lock with the door opener 1 door lock traps, can be provided to equip the rotary wing, for example, with a recess into which the door opener 1 engages with its locking portion 22 locking. This thus locking recess could be formed or arranged on a second rotary wing or with respect to the entire door system fixed element such as a door frame. This is a suitable solution for revolving doors, for example. With this type of locking the door opener 1 could be used with appropriate mounting even with sliding sashes.

Im Ergebnis bietet die Erfindung eine besonders einfache und kostengünstige Möglichkeit, ein Wegrütteln eines Sperrankers eines Türöffners zu verhindern, ohne den sonstigen Betrieb des Türöffners zu beeinflussen.As a result, the invention provides a particularly simple and cost-effective way to prevent a jolting a Sperrankers a door opener without affecting the other operation of the door opener.

Auch wird die Anordnung der im Türöffner anzuordnenden Teile nicht beeinflusst.Also, the arrangement of the parts to be arranged in the door opener is not affected.
