Description
Die Erfindung betrifft eine hydraulisch-mechanische Schließfolgeregelung für doppelflügelige Türen.The invention relates to a hydraulic-mechanical closing sequence control for double-leaf doors.
Eine solche Schließfolgeregelung ist aus der
Bei dieser Konstruktion hat das Übertragungselement, nämlich der Bowdenzug, einen großen Einfluss auf die Funktion. Bei einem Ausfall des Bowdenzuges, hervorgerufen z. B. durch falsche Einstellung, falsche Länge des Bowdenzuges, Lösen der Seilklemmungen usw., kommt es dazu, dass die richtige Schließlage der gefalzten Türflügel (Gang- und Standflügel) nicht eingehalten wird. Da jedoch Schließfolgeregelungen üblicherweise bei Türanlagen in Brandabschnitten eingesetzt werden, ergibt sich im Gefahrenfall bei einer nicht korrekt geschlossenen zweiflügeligen Tür ein erhöhtes Gefahrenpotential.With this construction, the transmission element, namely the Bowden cable, has a great influence on the function. In case of failure of the Bowden cable, caused z. B. by incorrect setting, wrong length of the Bowden cable, loosening the cable clamps, etc., it comes that the correct closed position of the folded door (aisle and inactive leaf) is not respected. However, since closing sequence controls are usually used in door systems in fire sections, there is an increased danger potential in the event of a danger when a double-leaf door is not correctly closed.
Eine weitere Schließfolgeregelung ist aus der
Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, den Stand der Technik weiterzubilden und eine hydraulisch-mechanische Schließfolgeregelung zu schaffen, die eine gesicherte Schließfolge einer zweiflügeligen Tür gewährleistet, dies aber mit möglichst wenigen und zudem einfach aufgebauten Bauteilen erreicht. Ferner soll die Schließfolgeregelung nachrüstbar sein.The object of the present invention is to further develop the prior art and to provide a hydraulic-mechanical closing sequence control that ensures a secure closing sequence of a two-leaf door, but this achieved with as few and also simply constructed components. Furthermore, the closing sequence control should be retrofitted.
Die Lösung dieser Aufgabe erfolgt jeweils durch die Merkmale der Ansprüche 1 und 2.The solution of this object is achieved in each case by the features of claims 1 and 2.
Erfindungsgemäß ist eine hydraulisch-mechanische Schließfolgeregelung für doppelflügelige, einen Standflügel und einen Gangflügel aufweisende Türen vorgesehen, wobei sowohl der Standflügel als auch der Gangflügel von je einem hydraulisch betätigbaren Türschließer oder Antrieb beaufschlagt sind, welcher mit einer Achse versehen ist, an der ein Gestänge angreift, das andererends über ein Gleitstück oder eine Rolle mit einer Gleitschiene zusammenwirkt, wobei auf der Achse des Türschließers für den Standflügel eine Kurvenscheibe angeordnet ist, welche mit einem Ventil zusammenwirkt, das den Türschließer des Gangflügels steuert. Neben der vorgenannten Ausführung eines Obentürschließers mit einer Gleitschiene kann auch eine Ausführung mit Scherengestänge gewählt werden.According to the invention, a hydraulically-mechanical closing sequence control is provided for double-winged doors having a fixed wing and a moving leaf, wherein both the inactive leaf and the active leaf are each acted upon by a hydraulically actuable door closer or drive, which is provided with an axle on which a linkage engages which at the other end cooperates via a slide or a roller with a slide rail, wherein on the axis of the door closer for the passive leaf a cam plate is arranged, which cooperates with a valve which controls the door closer of the active leaf. In addition to the above-mentioned embodiment of an overhead door closer with a slide rail and a version with scissor linkage can be selected.
Infolge dieser Ausgestaltung wird mit wenigen und einfach aufgebauten Bauteilen eine Schließfolgeregelung bereitgestellt, die eine gesicherte Schließfolge gewährleistet. Die Konstruktion hat darüber hinaus den Vorteil, dass die gesamte Schließfolgeregelung sehr kompakt aufgebaut ist und deshalb einfach und bequem ein- und ausgebaut werden kann, z. B. bei einer Reparatur oder zu Wartungszwecken. Da sie nur aus wenigen und relativ kleinen Einzelteilen besteht, ist nicht nur die Lagerhaltung der gesamten Schließfolgeregelung, sondern auch die Bereitstellung von Einzel- bzw. Ersatzteilen einfach und unkompliziert und benötigt wenig Platz. Bei Wartungs- und Reparaturarbeiten kann die Schließfolgeregelung nach der vorliegenden Erfindung wegen ihres geringen Gewichtes auch problemlos ein- oder ausgebaut werden. Infolge der Anordnung des Ventiles am Standflügel wird auch eine höhere Reaktionsgeschwindigkeit erzielt. Die gesamte Schließfolgeregelung ist kostengünstig, kann einfach in einem Systemträger montiert werden und ermöglicht eine einfache Einstellung. Auch eine Vormontage ist möglich. Durch die direkte Steuerung, ohne Verwendung von Zwischengliedern, kann direkt erkannt werden, in welcher Stellung sich der Türflügel befindet. Ferner gibt es keinen Eingriff in den Hydraulikkreislauf des Gangflügels durch Elemente des Türschließers des Standflügels.As a result of this embodiment, a closing sequence control is provided with a few and simply constructed components, which ensures a secure closing sequence. The design also has the advantage that the entire closure sequence control is very compact and therefore easy and convenient to install and remove, for. B. in a repair or for maintenance purposes. Since it consists of only a few and relatively small items, not only the storage of the entire closing sequence control, but also the provision of individual or spare parts is simple and straightforward and requires little space. For maintenance and repair work, the closing sequence control according to the present invention can also be easily installed or removed because of their low weight. Due to the arrangement of the valve on the inactive leaf also a higher reaction speed is achieved. The entire closing sequence control is inexpensive, can be easily mounted in a system carrier and allows easy adjustment. Also a pre-assembly is possible. Due to the direct control, without the use of pontics, it can be directly recognized in which position the door leaf is located. Furthermore, there is no interference with the hydraulic circuit of the active leaf by elements of the door closer of the passive leaf.
Unter Türschließern werden sowohl klassische Türschließer als auch Türantriebe mit einer elektrohydraulischen Öffnungshilfe und elektrohydraulische Türantriebe verstanden.Door closers are understood to mean both classic door closers and door drives with an electro-hydraulic opening aid and electro-hydraulic door drives.
Auch die Verwendung der vorgeschlagenen Schließfolgeregelung ist bei Bodentürschließern ohne weiteres möglich. In einem solchen Falle wird die Kurvenscheibe auf die Achse des Gangflügeltürbodentürschließers montiert und die Verbindung zu dem Ventil über entsprechende Hydraulikleitungen von dem Standflügelbodentürschließer aus hergestellt.The use of the proposed closing sequence control is possible with bottom door closers readily. In such a case, the cam is mounted on the axis of the gull-wing door closer and the connection to the valve is made via corresponding hydraulic lines from the bottom-wing door closer.
Es versteht sich, dass gemäß dieser Erfindung auch Türantriebe unter den Begriff Türschließer fallen.It is understood that according to this invention, door operators also fall under the term door closer.
Die Unteränsprüche haben vorteilhafte Weiterbildungen der Erfindung zum Inhalt.The subclaims have advantageous developments of the invention to the content.
Nach einer vorteilhaften Ausgestaltung erfolgt die Steuerung des Türschließers des Gangflügels über eine hydraulische Verbindung. Dies stellt eine einfache Steuerung sicher und ist zudem äußerst kostengünstig.According to an advantageous embodiment, the control of the door closer of the active leaf via a hydraulic connection. This ensures easy control and is also extremely cost effective.
Als hydraulische Verbindung kommen nach einer Ausführungsvariante Leitungen in Frage, die vorzugsweise in einen Systemträger integriert werden können. Z. B. können die Leitungen nach einer vorteilhaften Ausgestaltung gleich bei der Herstellung in den Systemträger hineinextrudiert werden. Dies stellt eine auch optisch ansprechende Lösung dar. Statt eines Systemträgers kann auch eine Gleitschiene verwendet werden, bei der z. B. zusätzliche Kammern vorhanden sind oder in einer Kammer zwei Hydraulikleitungen verlegt werden.As a hydraulic connection come in accordance with an embodiment variant lines in question, which can be preferably integrated into a system carrier. For example, according to an advantageous embodiment, the lines can be extruded into the system carrier during manufacture. This represents a visually appealing solution. Instead of a system carrier and a slide can be used in the z. B. additional chambers are available or two hydraulic lines are laid in a chamber.
Nach einer anderen Ausführungsvariante besteht die hydraulische Verbindung aus Schläuchen.According to another embodiment, the hydraulic connection consists of hoses.
Die erfindungsgemäße Schließfolgeregelung ist nach einer vorteilhaften Ausgestaltung so aufgebaut, dass das Ventil im geöffneten Zustand eine uneingeschränkte Bewegung des Gangflügels zulässt und im geschlossenen Zustand eine Bewegung des Gangflügels blockiert.The closing sequence control according to the invention is designed according to an advantageous embodiment so that the valve in the open state allows unrestricted movement of the active leaf and blocked in the closed state movement of the active leaf.
Damit sichergestellt ist, dass der Standflügel immer vor dem Gangflügel geschlossen wird, ist nach einer vorteilhaften Ausgestaltung das Ventil nur in einer einzigen Stellung der Kurvenscheibe geöffnet, in allen anderen Stellungen dagegen geschlossen. Diese geöffnete Stellung ist dann gegeben, wenn der Standflügel in seiner korrekten Schließstellung verharrt bzw. ab einem bestimmten kleinen Öffnungswinkel des Standflügels, der stets kleiner ist als der Öffnungswinkel des Gangflügels. Somit kann mit Ausnahme dieser ganz bestimmten Stellung des Standflügels der Gangflügel immer bewegt werden. Auf diese Weise ist mit einfachsten Mitteln die gewünschte Schließfolgeregelung sichergestellt. Sobald der Standflügel und der Gangflügel geöffnet sind (beide gleichzeitig) kann nur noch der Standflügel bewegt werden. Der Gangflügel bleibt in seiner Stellung stehen und kann erst wieder bewegt werden, wenn der Standflügel seine Schließstellung erreicht hat bzw. kurz vor der Schließstellung sich befindet.To ensure that the inactive leaf is always closed in front of the active leaf, according to an advantageous embodiment, the valve is opened only in a single position of the cam, in contrast, closed in all other positions. This open position is given when the inactive leaf remains in its correct closed position or from a certain small opening angle of the inactive leaf, which is always smaller than the opening angle of the active leaf. Thus, with the exception of this very specific position of the inactive leaf, the active leaf can always be moved. In this way, the desired closing sequence control is ensured with the simplest means. Once the inactive leaf and the active leaf are open (both at the same time), only the fixed leaf can be moved. The active leaf remains in its position and can only be moved again when the inactive leaf has reached its closed position or is just before the closed position.
Das in der erfindungsgemäßen Schließfolgeregelung verwendete Ventil ist nach einer vorteilhaften Weiterbildung mit einem Ventilkörper versehen, aus dem ein federbelasteter Stift herausragt. Dieser Stift wird in vorteilhafter Weise von einer Feder gegen die Nockenscheibe gedrückt. Dadurch wird sichergestellt, dass der Stift immer an der Nockenscheibe anliegt und somit eine funktionssichere Steuerung des Ventiles gewährleistet.The valve used in the closure sequence control according to the invention is provided according to an advantageous development with a valve body from which protrudes a spring-loaded pin. This pin is pressed in an advantageous manner by a spring against the cam. This ensures that the pin always rests against the cam disc and thus ensures a functionally reliable control of the valve.
Das Ventil ist in vorteilhafter Weise bei eingerücktem Stift geschlossen und bei ausgerücktem Stift geöffnet. Dadurch, dass ein in einem Kolbenraum befindlicher Zylinder, der über seine Verzahnung mit der Abtriebsachse des Türantriebes auf der Gangseite in Wirkverbindung steht, an jeder seiner Stirnflächen innerhalb des Kolbenraumes jeweils einen Druckraum mit Hydraulikflüssigkeit aufweist und diese beiden Druckräume jeweils an einer der zu dem Ventil, das an dem Antrieb des Standflügels montiert ist, führenden Leitungen angeschlossen ist, kann je nach Stellung des Ventiles (Auf und Zu) eine Blockierung des Kolbens auf der Gangseite oder eine freie Beweglichkeit bewirkt werden.The valve is advantageously closed when the pen is engaged and opened with the pin disengaged. Characterized in that a located in a piston chamber cylinder which is operatively connected via its teeth with the output shaft of the door drive on the gear side, at each of its end faces within the piston chamber each having a pressure chamber with hydraulic fluid and these two pressure chambers each at one of the valve , which is mounted on the drive of the passive leaf, is connected to leading lines, depending on the position of the valve (open and closed) can cause a blockage of the piston on the gear side or a free movement.
Während in einer ersten Ausführungsform der federbelastete Stift des Ventiles direkt mit der Kurvenscheibe zusammenwirkt, ist in einer zweiten Ausführungsform ein drehgelagerter Auslösehebel zwischengeschaltet. Dabei drückt der Stift des Ventiles auf eine Andruckplatte, die einerends an dem Auslösehebel angeordnet ist, während anderenends die Drehlagerung des einarmigen Auslösehebels erfolgt. Ferner weist der Auslösehebel einen Vorsprung auf, der direkt oder indirekt mit der Kurvenscheibe in Kontakt steht. Um Reibungsverluste so gering wie möglich zu halten, befindet sich an dem Vorsprung ein drehgelagertes Lager, z. B. ein Kugellager, welches an der Kurvenscheibe anliegt. Das Ventil kann innerhalb einer Gleitschiene eingebettet und durch das entsprechende Gleitstück des Standflügels betätigt werden. Eine derartige Anordnung kann sowohl bei einem sich schließenden als auch bei einem sich öffnenden Ventil ausgeführt werden. Ferner ist es möglich, dass das Ventil innerhalb einer weiteren Kammer der Gleitschiene angeordnet ist, in der auch gleichzeitig die Verbindungsleitungen zu dem Schließer oder der Vorrichtung des Gangflügels führen.While in a first embodiment, the spring-loaded pin of the valve interacts directly with the cam, in a second embodiment, a rotatably mounted release lever is interposed. In this case, the pin of the valve presses on a pressure plate, which is arranged at one end on the release lever, while the other end is the pivotal mounting of the one-armed release lever. Furthermore, the release lever has a projection which is directly or indirectly in contact with the cam. To keep friction losses as low as possible, located on the projection a rotatably mounted bearing, for. B. a ball bearing, which bears against the cam. The valve can be embedded within a slide rail and actuated by the corresponding slider of the inactive leaf. Such an arrangement can be carried out both in a closing and in an opening valve. Furthermore, it is possible for the valve to be arranged within a further chamber of the slide rail, in which at the same time the connecting lines lead to the closer or the device of the active leaf.
Ferner kann die vorbeschriebene Schließfolgeregelung nicht nur bei Bodentürschließern oder Obentürschließern angewendet werden, sondern auch bei Innentürschließer, die innerhalb des Türflügels eingebaut sind bzw. auch bei Rahmentürschließern, die oberhalb der Tür innerhalb der Zarge oder des Türrahmens sich befinden. Bei einer Ausführung innerhalb einer Schließfolgeanordnung bei Bodentürschließern kann darüber hinaus die Leitungsführung innerhalb eines separaten Kanales erfolgen.Furthermore, the above-described closing sequence control can be applied not only to floor spring closers or overhead door closers, but also to internal door closers installed inside the door leaf or also to frame door closers located above the door within the frame or door frame. In an embodiment within a closing sequence arrangement in floor spring closers, moreover, the routing can take place within a separate channel.

Die erfindungsgemäße Schließfolgeregelung eignet sich für eine doppelflügelige gefalzte Tür, bei welcher ein Gangflügel und ein Standflügel jeweils über einen Schwenkarm 4 mit einem Türrahmen oder den Türflügeln verbunden sind. Der Gangflügel, der Standflügel, der Türrahmen und die beiden Schwenkarme 4 sind allgemeiner Stand der Technik und deshalb hier nicht näher dargestellt oder erläutert.The closing sequence control according to the invention is suitable for a double-winged folded door in which a moving leaf and a stationary leaf are each connected via a
Die Schließfolgeregelung nach einer ersten bevorzugten Ausführungsform der vorliegenden Erfindung weist zwei hydraulisch betätigbare Türschließer 1, 2 auf, von denen der eine den Standflügel und der andere den Gangflügel beaufschlagt. Die beiden Türschließer 1, 2 sind im Wesentlichen gleich aufgebaut. Sie weisen jeweils eine Achse 3 auf, an der ein Schwenkarm 4 angeordnet ist, welcher mit dem Gangflügel bzw. dem Standflügel jeweils beweglich über ein Gleitstück bzw. eine Rolle und einer Gleitschiene verbunden ist.The closing sequence control according to a first preferred Embodiment of the present invention comprises two hydraulically actuated door closer 1, 2, of which one acts on the fixed leaf and the other the active leaf. The two door closers 1, 2 are constructed substantially the same. They each have an
Der mit dem Standflügel zusammenwirkende Türschließer 1 weist auf seiner Achse 3 zusätzlich eine Nockenscheibe 5 auf. Diese Nockenscheibe 5 ist im Wesentlichen rund ausgebildet und weist an einer Stelle eine Einbuchtung 6 auf. Die Nockenscheibe 5 kann auch nachträglich mit der Achse 3 verbunden werden. Die Verbindung ist dabei kraft- und formschlüssig ausgeführt.The cooperating with the passive leaf door closer 1 has on its
Mit der Nockenscheibe 5 wirkt ein am Türschließer 1 angebrachtes Ventil 7 zusammen. Das Ventil 7 weist ein Ventilgehäuse 8 auf, aus dem ein Stift 9 vorsteht, der unter der Wirkung einer Feder 10 steht, welche versucht, den Stift 9 aus dem Gehäuse 8 herauszudrükken.With the
An das Ventil 7 sind Leitungen oder Schläuche 11 angeschlossen, die mit ihrem anderen Ende mit dem Hydraulikkreislauf des Türschließers 2 für den Gangflügel verbunden sind. Die Leitungen oder Schläuche 11 können auch direkt bei der Herstellung in einen Systemträger 12 hineinextrudiert werden.To the
Die Konstruktion des Ventiles 7 ist so gewählt, dass das Ventil 7 geöffnet ist, wenn der Stift 9 aus dem Gehäuse 8 herausgedrückt ist. Die Kraft zum Herausdrücken des Stiftes 9 wird über die Feder 10 realisiert. In dieser Stellung kann der Gangflügel ohne Einschränkung frei bewegt werden. Wenn der Stift 9 des Ventiles 7 aus dem Gehäuse 8 vorsteht, wie in den
Im Folgenden wird nun die Funktion der erfindungsgemäßen Schließfolgeregelung erläutert.The function of the closing sequence control according to the invention will now be explained below.
In
Wird der Standflügel nach dem Gangflügel geöffnet, dreht sich die Nockenscheibe 5, der Stift 9 tritt aus der Einbuchtung 6 heraus und wird in das Gehäuse 8 des Ventiles 7 gedrückt. In dieser Stellung ist das Ventil 7 geschlossen. Dies hat zur Folge, dass nunmehr ein Fluss der Hydraulikflüssigkeit im Türschließer 2 für den Gangflügel nicht mehr ermöglicht wird und der Gangflügel somit nicht mehr bewegt werden kann.If the inactive leaf is opened after the active leaf, the
Der Gangflügel kann sich erst dann wieder bewegen und wird über den Antrieb 2 geschlossen, wenn der Standflügel in seiner Schließstellung ist bzw. sich kurz davor befindet und das Ventil 7 den Durchfluss durch die Leitungen 11 zum Antrieb 2 des Gangflügels wieder freigibt, so dass in jedem Falle sichergestellt ist, das der Standflügel vor dem Gangflügel geschlossen wird. Dieses ist insbesondere dort von Wichtigkeit, wo der Standflügel und der Gangflügel jeweils mit einem Falz ausgestattet sind und die Flügel sich in einem Brandabschnitt befinden.The active leaf can only move again and is closed via the drive 2 when the inactive leaf is in its closed position or is just before it and the
In der
Die Kurvenscheibe 5 ist auf der Achse 3 des Türschließers des Gangflügels so angeordnet, dass die Einstellung stufenlos erfolgen kann. Bei einer genauen Einstellung und damit Auslösung des Ventiles 8 über die Kurvenscheibe 5 wird diese auf der Achse 3 entsprechend festgesetzt.The
Um die Baugruppe, bestehend aus Ventil 7 und Auslösehebel 14, einfach montieren zu können, befindet sich diese auf einem Montagehebel 13, der an dem Türschließer des Gangflügels kraft- und formschlüssig befestigt wird.To the assembly, consisting of
Eine weitere Möglichkeit, den Türschließer des Gangflügels über den Standflügel zu steuern, besteht darin, dass z. B. das Ventil 7 innerhalb einer Gleitschiene 34 eingebaut sein kann. Um das Ventil 7 mit dem Stift 9 betätigen zu können, kann z. B., wie es aus der
Neben den vorbeschriebenen Ausführungen eines Türschließers 1 und 2 kann natürlich erfindungsgemäß auch ein hydraulisch mechanischer Antrieb verwendet werden. Hierbei kommt es auf die Forderung an, ob der Antrieb die Tür nur öffnen soll und der Schließvorgang wird dann über eine innerhalb des Antriebes befindliche Feder bewerkstelligt oder der Antrieb wird auch für den Schließvorgang der Tür betreiben.In addition to the above-described embodiments of a door closer 1 and 2, of course, according to the invention also a hydraulic mechanical drive can be used. This depends on the demand, whether the drive should only open the door and the Closing operation is then accomplished via a spring located within the drive or the drive will also operate for the closing of the door.
Die
Der Druckraum 33 auf der Federseite ist durch eine Hydraulikleitung ebenfalls mit dem Öltank 32 verbunden. Innerhalb dieser Leitung befinden sich parallel angeordnet ein Öffnungsgeschwindigkeitsventil 23 und ein Öffnungsdämpfungsventil 24.The
Der Aufbau der Vorrichtung für den Gangflügelantrieb ist analog der des Standflügelantriebes, mit einer Ausnahme, dass von dem Öltank 32 eine Leitung 11 abgeht, in der das Ventil 7 angeordnet ist. Die zweite Verbindung zu dem Ventil 7 über die Leitung 11 geht über die bereits beschriebenen Ventile 21 und 22 mit einem noch dazwischen befindlichen Magnetventil 31 zu dem Druckraum 20 der Pumpenseite. Der Stift 9 des Ventiles 7 wirkt dabei in der schematischen Darstellung mit der Kurvenscheibe 5 gemäß der vorbeschriebenen Art.und Weise zusammen.The structure of the device for the active leaf drive is analogous to that of the passive leaf drive, with the exception that from the oil tank 32 a
