Description
Die Erfindung betrifft einen fernbetätigbaren Türöffner zur Installation in oder an einer Tür, die einen ortsfesten Türrahmen und einen an dem Türrahmen bewegbar gelagerten Türflügel aufweist.The invention relates to a remote-controlled door opener for installation in or on a door having a fixed door frame and a door frame movably mounted on the door.
Es sind Türöffner mit Schwenkfalle bekannt, die eine als Drehfeder ausgebildete Rückstellfeder aufweisen, die die Schwenkfalle in Sperrstellung beaufschlagt, und zwar derart, dass die Schwenkfalle in ihrer Sperrstellung an einem Gehäuseanschlag, d. h. an einer Wandung oder einem anderen Anschlag des Türöffnergehäuses anliegt.There are known door opener with a pivoting latch, which have a return spring formed as a torsion spring, which acts on the pivotal latch in the blocking position, in such a way that the pivotal latch in its locking position on a housing stop, d. H. abuts against a wall or other stop of the door opener housing.
Die
Der Nachteile dieser bereits bekannten Türöffner ist, dass die Rückstellfeder eine relativ hohe Federkraft aufweisen muss, um sicherzustellen, dass die Tür bei ausgelöstem, d.h. freigegebenem Türöffner gegen Windlasten geschlossen bleibt, d. h. die Türöffnerfalle in Sperrstellung verbleibt, solange die Tür nicht bestimmungsgemäß geöffnet wird. Es ergeben sich nachteilig hohe Rückstellgeräusche.The disadvantages of these already known door openers is that the return spring must have a relatively high spring force to ensure that the door is closed when triggered, ie released door opener against wind loads remains, ie the door opener trap remains in the locked position, as long as the door is not opened as intended. There are disadvantageously high return noises.
Die
Die
Die Aufgabe der Erfindung liegt darin, einen Türöffner mit sicherer Arretierung der Türöffnerfalle zu schaffen, wobei jedoch nur geringe Rückstellgeräusche mit der Rückstellfeder erhalten werden.The object of the invention is to provide a door opener with secure locking of the door opener trap, but only small reset noises are obtained with the return spring.
Erfindungsgemäß wird diese Aufgabe mit dem Gegenstand des Patentanspruchs 1 gelöst. Es wird damit ein fernbetätigbarer Türöffner vorgeschlagen zur Installation in oder an einer Tür, die einen ortsfesten Türrahmen und einen an dem Türrahmen bewegbar gelagerten Türflügel aufweist, wobei der fernbetätigbare Türöffner ein Türöffnergehäuse aufweist, in welchem eine bewegbare Türöffnerfalle und eine elektrisch schaltbare Sperreinrichtung gelagert sind. Die elektrisch schaltbare Sperreinrichtung wirkt unmittelbar oder mittelbar mit der Türöffnerfalle derart zusammen, dass die Türöffnerfalle eine Sperrstellung und nach elektrischer Freischaltung der Sperreinrichtung eine Freigabestellung einnehmen kann. Die Türöffnerfalle ist von einer Rückstellfeder in ihrer Sperrstellung beaufschlagt, wobei vorgesehen ist, dass mindestens eine mit der Türöffnerfalle unmittelbar oder mittelbar zusammenwirkende Kugelrasteinrichtung vorgesehen ist. Es ist vorgesehen, dass die Türöffnerfalle durch die Kugelrasteinrichtung in ihrer Sperrstellung feststellbar ist. Hierbei ist vorgesehen, dass die Kugelrasteinrichtung eine Feder aufweist, die separat von der Rückstellfeder ausgebildet ist. Es ist vorgesehen, dass die über die Kugelrasteinrichtung bewirkte Feststellung beim Öffnen der Tür unter Überdrücken der Feder der Kugelrasteinrichtung aufhebbar ist.According to the invention, this object is achieved with the subject matter of
Wesentlich bei der erfingungsgemäßen Lösung ist, dass die Vorspannung der Feder der Kugelrasteinrichtung einstellbar ist. Dies erfogt dadurch, dass die Feder der Kugelrasteinrichtung auf einem über eine Einstelleinrichtung positionsverstellbaren Lager abgestüzt ist.Essential in the solution according to the invention is that the bias of the spring of the ball latch device is adjustable. This erfogt by the fact that the spring of the ball detent device is abgestüzt on a positionally adjustable via a setting bearing.
Der erfindungsgemäße Türöffner weist für die stabile Positionierung der Türöffnerfalle in der Sperrstellung also eine Kugelverrastung auf, um die Türöffnerfalle gegen mechanische Beaufschlagung der Tür, z.B. gegen Windlast in Position zu halten, wenn der Türöffner bereits elektrisch ausgelöst, d.h. freigegeben ist und die Tür aber noch nicht bestimmungsgemäß geöffnet wird. In dieser Position ist die Tür geschlossen, die Schlossfalle hintergreift die Türöffnerfalle. Auf die Türöffnerfalle wirkt in dieser Position die Federkraft der vorgespannten Feder der Kugelrasteinrichtung und die der vorgespannten Rückstellfeder als eine beim bestimmungsgemäßen Öffnen überdrückbare Haltekraft ein. Durch diese Aufteilung der Federeinrichtung ist es möglich, die Haltekraft der Türöffnerfalle getrennt von der Rückstellfeder einzustellen. Damit kann realisiert werden, dass trotz hoher Haltekraft eine sanfte Rückstellung der Türöffnerfalle erfolgt. Nach dem Überwinden der Haltekraft durch Überdrücken aus dem Anfangspunkt beim Öffnen kann eine mit dem erfindungsgemäßen Türöffner ausgerüstete Tür mit geringem Kraftaufwand geöffnet werden. Die Türöffnerfalle wird sodann nach dem Öffnen ohne wesentliche Geräuschentwicklung durch die Rückstellfeder selbsttätig zurückgestellt. Es kann ein abhängig von der Türstellung gesteuerter Zwischenanschlag vorgesehen sein, über den die Türöffnerfalle in einer Warteposition gehalten wird, so dass sie erst dann selbsttätig in Schließstellung kommt, wenn die Tür in Schließlage ist.The door opener according to the invention therefore has a ball lock for the stable positioning of the door opener latch in the blocking position in order to lock the door opener against mechanical loading of the door, e.g. against wind load when the door opener is already electrically triggered, i. is released and the door is not yet opened as intended. In this position, the door is closed, the latch falls behind the door latch. In this position, the spring force of the prestressed spring of the ball latching device and that of the pretensioned return spring acts as a retaining force that can be overridden during normal opening. By this division of the spring device, it is possible to adjust the holding force of the door opener trap separately from the return spring. This can be realized that despite high holding force gentle reset of the door latch occurs. After overcoming the holding force by overpressing from the starting point when opening a door equipped with the door opener invention can be opened with little effort. The door opener trap is then automatically reset after opening without significant noise by the return spring. It may be provided depending on the door position controlled intermediate stop, via which the door opener latch is held in a waiting position, so that it automatically comes into the closed position only when the door is in the closed position.
Bei bevorzugten Ausführungen ist vorgesehen, dass die Feder der Kugelrasteinrichtung eine höhere Federstärke als die Rückstellfeder der Türöffnerfalle aufweist.In preferred embodiments, it is provided that the spring of the ball latching device has a higher spring strength than the return spring of the door opener latch.

Die Kugelrasteinrichtung kann mit der Türöffnerfalle unmittelbar oder mittelbar zusammenwirken. Bei bevorzugten Ausführungen ist vorgesehen, dass die Kugelrasteinrichtung so angeordnet ist, dass sie zwischen einerseits der Türöffnerfalle und andererseits dem Türöffnergehäuse oder einem in dem Türöffnergehäuse gelagerten Bauteil und/oder einem über die Sperreinrichtung schaltbarem Bauteil einwirkt. Ausführungen, bei denen die Kugelrasteinrichtung mittelbar mit der Türöffnerfalle zusammenwirkt, können z. B. so ausgebildet sein, dass die Kugelrasteinrichtung mit einem auf die Türöffnerfalle einwirkenden Sperrglied, z. B. einem im Gehäuse gelagerten Wechsel zusammenwirkt. Es sind auch Ausführungen möglich, bei denen zusätzlich auch der Anker des Elektromagneten mit einer Kugelrasteinrichtung zusammenwirken. Die Kugelrasteinrichtung kann bei unterschiedlichen bevorzugten Ausführungen eine Einrichtung zur Einstellung der Mindesöffnungskraft an einem der Halte- oder Verriegelungselemente darstellen. Ferner kann bei bestimmten Ausführungen die Kugelrasteinrichtung gegebenenfalls auch zur Rüttelsicherheit des Türöffners beitragen, insbesondere wenn der Anker mit einer Kugelrasteinrichtung zusammenwirkt.The ball latching device can interact directly or indirectly with the door opener latch. In preferred embodiments, it is provided that the ball locking device is arranged so that it acts between on the one hand the door opener trap and on the other hand the door opener housing or a mounted in the door opener housing component and / or a switchable via the blocking device component. Versions in which the ball locking device interacts indirectly with the door latch, z. B. be designed so that the ball locking device with a force acting on the door latch latching member, z. B. interacts with a mounted in the housing change. Embodiments are also possible in which, in addition, the armature of the electromagnet cooperate with a ball latching device. The ball locking device may represent a device for adjusting the Mindesöffnungskraft on one of the holding or locking elements in different preferred embodiments. Furthermore, in certain embodiments, the ball latching device may possibly also contribute to the vibration safety of the door opener, in particular when the armature cooperates with a ball latching device.

Die Türöffnerfalle 12 ist in dem dargestellten Ausführungsbeispiel als Schwenkfalle ausgebildet, die um eine Schwenkachse 12s schwenkbar in dem Türöffnergehäuse 11 gelagert ist. Wesentlich ist, dass die Türöffnerfalle durch eine Kugelrasteinrichtung 13 in ihrer Sperrstellung festgestellt wird, wobei diese Feststellung durch entsprechende Krafteinwirkung beim Öffnen überdrückbar ist. In dem dargestellten Fall sind zwei Kugelrasteinrichtungen 13 vorgesehen, und zwar jeweils eine an jeder der beiden Stirnseiten der Türöffnerfalle angeordnet, also symmetrisch auf die Türöffnerfalle 12 einwirkend. Außerdem ist eine Rückstellfeder 14 vorgesehen, die die Türöffnerfalle in ihrer Sperrstellung beaufschlagt. In dem Ausführungsbeispiel in
Der Türöffner 1 ist an einer in den Figuren nicht dargestellten Tür montiert. Die Tür weist einen Türrahmen mit einem daran beweglich gelagerten Türflügel auf. Der Türöffner ist vorzugsweise so gelagert, dass das Türöffnergehäuse 11 türrahmenfest, vorzugsweise versenkt im Türrahmen gelagert ist und die Türöffnerfalle 12 dabei mit einer Schlossfalle des Türflügels zusammenwirkt. Die umgekehrte Montage, bei der das Türöffnergehäuse 11 türflügelfest montiert ist und die Türöffnerfalle 12 mit einer türrahmenseitigen Schlossfalle oder dergleichen zusammenwirkt, ist alternativ möglich.The
Bei den Ausführungsbeispielen der Figuren ist die Türöffnerfalle 12 mehrstückig ausgebildet, bestehend aus einem Grundkörper 12a und einem Aufschraubstück. Die Türöffnerfalle 12 ist in
Die beiden Kugelrasteinrichtungen 13 sind bei dem dargestellten Ausführungsbeispiel jeweils als Baueinheit bestehend aus einer Kugel 13k und einer Schraubendruckfeder 13f ausgebildet. Diese Baueinheit ist in einer Durchgangsbohrung einer seitlichen Gehäusewandung, die an die jeweilige Stirnseite der Türöffnerfalle 12 angrenzt, aufgenommen. Das von der Türöffnerfalle abgewandte Ende der Durchgangsbohrung 11d ist in dem dargestellten Fall mit einem Innengewinde ausgebildet, in welchem eine Madenschraube 13s eingeschraubt ist. Die Schraubendruckfeder 13f mit der Kugel 13k sind in der Bohrung 11d so aufgenommen, dass die Schraubendruckfeder mit ihrem einen Ende auf dem freien Ende der Madenschraube 13s abgestützt ist und mit ihrem anderen Ende die Kugel 13k abstützt. Die Kugel 13k ragt teilweise aus der Bohrung 11 d heraus und greift in eine an der Stirnfläche der Türöffnerfalle 12 ausgebildete Rastausnehmung 12r ein, die als entsprechende Vertiefung in der Stirnfläche der Türöffnerfalle ausgebildet ist. Die Vorspannung der Schraubendruckfeder 13f ist durch die Madenschraube 13s einstellbar, da das freie Ende der Madenschraube 13s ein bewegbares Auflager für die Schraubendruckfeder 13f bildet. Die Türöffnerfalle ist in dem Türöffnergehäuse so gelagert, dass der Eingriff der Kugelrasteinrichtungen 13 in den Rastausnehmungen 12r der Türöffnerfalle 12 vorliegt, wenn die Türöffnerfalle in ihrer Sperrstellung steht.The two
Durch die elektrisch schaltbare Sperreinrichtung 15 des Türöffners wird die Türöffnerfalle 12 in ihrer Sperrstellung elektrisch schaltbar festgestellt. Hierfür weist die Sperreinrichtung 15 ein in
Wenn die elektrische Feststellung der Türöffnerfalle durch entsprechende Schaltung der elektrischen Sperreinrichtung 15 aufgehoben wird, kann die Türöffnerfalle 12 beim Öffnen der Tür über den Andruck der Schlossfalle in ihre Freigabestellung geschwenkt werden. Hierbei muss nach der elektrischen Freischaltung der Sperreinrichtung 15 zunächst die Kugelverrastung der Kugelrasteinrichtungen 13 überdrückt werden. Hierbei wird die Kugel 13k der Kugelrasteinrichtung 13 in die Aufnahmebohrung 11 d hineingedrückt, wobei die Schraubenfeder 13f komprimiert wird. Die Kugel 13k kommt dabei außer Eingriff der Rastausnehmung 12r und kann auf der der Rastausnehmung angrenzenden Anschlag- und Führungsfläche auf der Stirnseite der Türöffnerfalle gleiten. Für dieses Überdrücken der Kugelrasteinrichtungen muss in dem Anfangspunkt eine relativ hohe Kraft aufgewendet werden, um jeweils die Kugel 13k aus der Rastausnehmung 12r unter Kompression der vorgespannten Schraubendruckfeder 13f zu drücken. Sobald dann die Kugel 13k nicht mehr in die Rastausnehmung 12r eingreift, ist nur noch die vergleichsweise geringe und konstante Reibungskraft zu überwinden, die durch Reibung der Kugel 13k auf der Stirnfläche der Türöffnerfalle bzw. dort auf der Anschlag- und Führungsfläche entsteht. Gleichzeitig ist zum weiteren Auslenken nur noch die an der Türöffnerfalle eingreifende Rückstellfeder 14 zu Überdrücken. Die Rückstellfeder 14 kann bei den erfindungsgemäßen Ausführungsbeispielen vorzugsweise als relativ "weiche" Feder ausgebildet sein, da die Türöffnerfalle 12 in der Schließstellung der Tür über die Kugelverrastung mit entsprechend Vorhaltekraft gegen mechanische Beaufschlagung, wie z.B. Windkräfte usw. sicher gehalten wird. Die Federkraft der Schraubendruckfeder 13f kann entsprechend hoch eingestellt werden. Die Rückstellfeder 14 kann, wie gesagt, als relativ "weiche" Feder ausgebildet sein, die eine flachere Federkennlinie aufweist als eine nach dem Stand der Technik ausgebildete Rückstellfeder, bei der die Schlossfalle keine Kugelverrasteinrichtung aufweist.If the electrical detection of the door latch latch is canceled by appropriate circuit of the
Dagegen ergibt sich für einen erfindungsgemäßen Türöffner ein ganz anderer Verlauf des Kraft-Weg-Diagramms der Türöffnerfalle.

Wird nun der Elektromagnet betätigt, schwenkt der Schwenkhebel 16 aus und gibt den Wechsel 15w frei. Sobald die Türöffnerfalle 12 aus der Sperrstellung in die Freigabestellung geschwenkt wird, wird der Wechsel 15w über das Druckstück 15d um die Drehachse 15a geschwenkt. Dabei wirkt die Rückstellfeder 15f der Drehung entgegen. Eine gesonderte Rückstellfeder, die unmittelbar mit der Türöffnerfalle 12 zusammenwirkt, wie weiter oben in
Der Wechsel 15w wirkt aufgrund seiner Ausbildung als zweiarmiger Hebel mit einem langen und einem kurzen Hebelarm als Kraftverstärker, so dass vom Elektromagnet nur relativ kleine Kräfte aufgebracht werden müssen, um die Sperreinrichtung 15 zu entsperren.The

Außerdem sind abgewandelte Ausführungen mit schwenkbarer Türöffnerfalle oder linear beweglicher Türöffnerfalle vorgesehen, bei denen eine oder mehrere Kugelrasteinrichtungen 13 in der Türöffnerfalle angeordnet sind und die federbelastete Kugel der Kugeleinrichtung jeweils sich an einer gehäusefesten Wandung des Türöffnergehäuses abstützt. Es sind hierbei Ausführungen möglich, die gleich aufgebaut sind wie die vorangehend beschriebenen Ausführungsbeispiele der Figuren und dabei jedoch lediglich die umgekehrte Anordnung der Kugelverrasteinrichtung 13 realisieren, d.h. die Baueinheit 13 bestehend aus Kugel 13k und Schraubendruckfeder 13f ist in einer Aufnahmebohrung der Türöffnerfalle 12 angeordnet und die Rastausnehmung 12r ist in der der Kugel zugewandten Wandung des Gehäuses ausgebildet.In addition, modified versions are provided with pivoting door opener latch or linearly movable door opener trap, in which one or
