Description

Die Erfindung betrifft einen Antrieb zum Öffnen und Schließen eines Flügels eines Fensters, einer Tür oder dergleichen, mit einer im Profil des Fenster- bzw. Türrahmens integrierbaren motorischen Antriebseinheit, die zur Betätigung des Fenster- bzw. Türflügels mit einem einseitig biegesteifen Kraftübertragungselement, insbesondere einer Kette oder dergleichen, zusammenwirkt, das an seinem mit dem Flügel verbindbaren Ende mit einem Endstück versehen ist, das in einem im Flügelprofil integrierbaren Kraftübertragungselement-Bock festsetzbar ist. Sie betrifft ferner ein Fenster, eine Tür oder dergleichen mit einem solchen Antrieb.The invention relates to a drive for opening and closing a sash of a window, a door or the like, with a motor drive unit which can be integrated in the profile of the window or door frame and which is used to actuate the window or door sash with a force-transmitting element that is rigid on one side, in particular a Chain or the like, cooperates, which is provided at its end which can be connected to the wing with an end piece which can be fixed in a force transmission element block which can be integrated in the wing profile. It also relates to a window, a door or the like with such a drive.

Bei integrierten Antrieben der eingangs genannten Art, zu denen beispielsweise integrierte Kettenantriebe zählen, ist sowohl die motorische Antriebseinheit als auch der Kraftübertragungselement- bzw. Kettenbock jeweils im Fenster- bzw. Türprofil integriert. Dabei ist bei solchen integrierten Antrieben das Endstück des Kraftübertragungselements im Normalfall nicht nur zum motorischen Öffnen und Schließen des Fenster- bzw. Türflügels, sondern in der Regel auch bei geschlossenem Flügel im Kraftübertragungselement- bzw. Kettenbock festgesetzt. Fällt nun aber die motorische Antriebseinheit aus, so ist es zumindest schwierig, wenn nicht gar ausgeschlossen, das Fenster bzw. die Tür zu öffnen, um an die motorische Antriebseinheit heranzukommen. Die Verbindung zwischen dem Fenster- bzw. Türflügel und dem Rahmen muss dazu von außen mechanisch lösbar sein, was in den meisten Fällen nun aber sehr umständlich ist und mit relativ hohem Kraftaufwand einhergeht oder gar eine teilweise Zerstörung des Fensters bzw. der Tür erfordert.In the case of integrated drives of the type mentioned at the outset, which include, for example, integrated chain drives, both the motor drive unit and the power transmission element or chain bracket are each integrated in the window or door profile. With such integrated drives, the end piece of the power transmission element is normally fixed in the power transmission element or chain bracket not only for motorized opening and closing of the window or door sash, but also when the sash is closed. If, however, the motorized drive unit fails, it is at least difficult, if not impossible, to open the window or the door in order to get to the motorized drive unit. The connection between the window or door sash and the frame must be mechanically detachable from the outside, which in most cases is very cumbersome and involves a relatively high expenditure of force or even requires partial destruction of the window or door.

Der Erfindung liegt die Aufgabe zugrunde, einen integrierten Antrieb der eingangs genannten Art anzugeben, bei dem die zuvor erwähnten Nachteile beseitigt sind. Dabei soll insbesondere gewährleistet sein, dass die Verbindung zwischen dem Endstück des Kraftübertragungselements und dem Kraftübertragungselement-Bock und damit die Verbindung zwischen Flügel und Rahmen im Notfall bzw. bei einem jeweiligen Ausfall der motorischen Antriebseinheit mit minimalem Kraftaufwand auf möglichst einfache und zuverlässige Weise unter Vermeidung einer Beschädigung des Fensters bzw. der Tür manuell von außen lösbar ist.The invention is based on the object of specifying an integrated drive of the type mentioned at the beginning, in which the aforementioned disadvantages are eliminated. In particular, it should be ensured that the connection between the End piece of the power transmission element and the power transmission element block and thus the connection between the sash and the frame in an emergency or in the event of a failure of the motorized drive unit, which can be manually released from the outside with minimal effort, avoiding damage to the window or door is.

Erfindungsgemäß wird diese Aufgabe gelöst durch einen Antrieb mit den Merkmalen des Anspruchs 1. Bevorzugte Ausführungsformen des erfindungsgemäßen Antriebs ergeben sich aus den Unteransprüchen, der vorliegenden Beschreibung sowie der Zeichnung.According to the invention, this object is achieved by a drive with the features of claim 1. Preferred embodiments of the drive according to the invention emerge from the subclaims, the present description and the drawing.

It is only necessary to exert a pressing force on the locking connection by means of a tool that can be passed through the opening in the wing profile in order to release it.

Vorteilhafterweise umfasst die Rastverbindung zumindest ein im oder am Kraftübertragungselement-Bock gelagertes, federnd in eine entsprechende Aufnahme des Endstücks des Kraftübertragungselements einrastbares Eingriffselement. Alternativ oder zusätzlich kann die Rastverbindung auch zumindest ein im oder am Endstück des Kraftübertragungselements gelagertes, federnd in eine entsprechende Aufnahme des Kraftübertragungselement-Bocks einrastbares Eingriffselement umfassen. Dabei kann ein jeweiliges Eingriffselement beispielsweise einen verschiebbar im Kraftübertragungselement-Bock bzw. Endstück des Kraftübertragungselements gelagerten, federnd vorbelasteten Bolzen oder dergleichen umfassen. Zum Auslösen der Rastverbindung kann ein jeweiliges Eingriffselement durch die mittels des Werkzeugs aufgebrachte Drückkraft entgegen der jeweiligen Federkraft aus der betreffenden Aufnahme herausgedrängt werden, womit das Endstück des Kraftübertragungselements freikommt. Zudem kann ein jeweiliges Eingriffselement eine mit einer Schrägfläche des Endstücks des Kraftübertragungselements bzw. dem Kraftübertragungselement-Bock zusammenwirkende Schrägfläche aufweisen, so dass es beim Einsetzen des Endstücks in den Kraftübertragungselement-Bock entgegen der jeweiligen Federkraft zunächst zurückgedrängt wird, um anschließend automatisch wieder einzurasten.The latching connection advantageously comprises at least one engagement element which is mounted in or on the force transmission element block and can be resiliently latched into a corresponding receptacle in the end piece of the force transmission element. As an alternative or in addition, the latching connection can also comprise at least one engaging element which is mounted in or on the end piece of the force transmission element and can be resiliently latched into a corresponding receptacle of the force transmission element block. In this case, a respective engagement element can comprise, for example, a resiliently preloaded bolt or the like that is slidably mounted in the force transmission element bracket or end piece of the force transmission element. To release the latching connection, a respective engagement element can be pushed out of the relevant receptacle against the respective spring force by the pressing force applied by means of the tool, with the result that the end piece of the force transmission element is released. In addition, a respective engagement element can have an inclined surface cooperating with an inclined surface of the end piece of the force transmission element or the force transmission element block, so that when the end piece is inserted into the force transmission element block, it is initially pushed back against the respective spring force and then automatically re-engages.

Gemäß einer bevorzugten praktischen Ausführungsform des erfindungsgemäßen Antriebs umfasst die Rastverbindung zwei einander gegenüberliegende, jeweils axial verschiebbar im Kraftübertragungselement-Bock gelagerte Bolzen oder dergleichen, die sich von einander gegenüberliegenden Seiten her in einen Aufnahmebereich des Kraftübertragungselement-Bocks für das Endstück des Kraftübertragungselements erstrecken, federnd aufeinander zu vorbelastet und zum Festsetzen des Endstücks des Kraftübertragungselements im Aufnahmebereich von den beiden einander gegenüberliegenden Seiten her in eine Öffnung des Endstücks des Kraftübertragungselements einrastbar sind.According to a preferred practical embodiment of the drive according to the invention, the latching connection comprises two opposing bolts or the like, each axially displaceable in the power transmission element block, which extend from opposite sides into a receiving area of the force transmission element block for the end piece of the force transmission element, are resiliently preloaded towards one another and can be snapped into an opening of the end piece of the force transmission element from the two opposite sides to fix the end piece of the force transmission element in the receiving area .

Dabei kann das Endstück des Kraftübertragungselements mit einer durchgehenden Öffnung versehen sein, in die die beiden Bolzen von entgegengesetzten Seiten her einrastbar sind, oder auf einander gegenüberliegenden Seiten jeweils mit einer getrennten Öffnung versehen sein, in die jeweils ein Bolzen einrastbar ist.The end piece of the force transmission element can be provided with a through opening into which the two bolts can be latched from opposite sides, or each with a separate opening into which a bolt can be latched on opposite sides.

Es ist damit nicht nur auf einfache Weise eine zuverlässige Verriegelung des Endstücks des Kraftübertragungselements im Kraftübertragungselement-Bock sichergestellt. Es ist im Notfall auch ein einfaches Lösen der Rastverbindung möglich, indem über die mittels des Werkzeugs manuell von außen aufgebrachte Drücckraft die federnd aufeinander zu vorbelasteten Bolzen entgegen den Federkräften auseinander und damit aus dem Endstück des Kraftübertragungselements herausgezogen werden. Nachdem das Endstück aus dem Kraftübertragungselement-Bock herausgenommen ist, gelangen die Bolzen aufgrund der sie beaufschlagenden Federkräfte automatisch wieder in ihre Ausgangslage.Reliable locking of the end piece of the force transmission element in the force transmission element bracket is thus not only ensured in a simple manner. In an emergency, the locking connection can also be easily released by pulling the spring-loaded bolts apart against the spring forces and thus pulling them out of the end piece of the force transmission element using the pressure force applied manually from the outside by means of the tool. After the end piece has been removed from the force transmission element block, the bolts automatically return to their original position due to the spring forces acting on them.

Der Kraftübertragungselement-Bock ist zweckmäßigerweise mit einer Auslösemechanik versehen, über die mit einer jeweiligen Beaufschlagung durch eine mittels des Werkzeugs aufgebrachte Drückkraft die federnd aufeinander zu vorbelasteten Bolzen zum Lösen der Rastverbindung und zur Freigabe des Endstücks des Kraftübertragungselements entgegen der Federkräfte auseinanderpressbar sind.The power transmission element bracket is expediently provided with a release mechanism, via which the resiliently preloaded bolts to release the locking connection and to release the end piece of the power transmission element can be pressed apart against the spring forces with a respective application of a pressing force applied by the tool.

Dabei umfasst die Auslösemechanik des Kraftübertragungselement-Bocks gemäß einer vorteilhaften praktischen Ausführungsform des erfindungsgemäßen Antriebs zwei einander gegenüberliegende, jeweils axial verschiebbar im Kraftübertragungselement-Bock gelagerte, federnd aufeinander zu vorbelastete und den Aufnahmebereich seitlich begrenzende Lagerelemente, an denen jeweils einer der beiden Bolzen fest abgestützt ist und über die die Bolzen federnd aufeinander zu vorbelastet sind.The trigger mechanism of the force transmission element block comprises according to an advantageous practical embodiment of the drive according to the invention two opposing bearing elements, each axially displaceable in the power transmission element block, resiliently preloaded towards one another and laterally delimiting the receiving area, on each of which one of the two bolts is firmly supported and via which the bolts are resiliently preloaded towards one another.

Zum Lösen der Rastverbindung sind in diesem Fall die federnd aufeinander zu vorbelasteten Lagerelemente entgegen den diese beaufschlagenden Federkräften auseinanderzudrücken, womit entsprechend die beiden Bolzen auseinandergezogen werden, um das Endstück des Kraftübertragungselements freizugeben.To release the latching connection, the resiliently preloaded bearing elements are to be pressed apart in this case against the spring forces acting on them, whereby the two bolts are accordingly pulled apart to release the end piece of the force transmission element.

Dabei ist insbesondere von Vorteil, wenn die Auslösemechanik ein zwischen den beiden federnd aufeinander zu vorbelasteten Lagerelementen angeordnetes, senkrecht zu den Lagerelementen verschiebbares und durch das Werkzeug beaufschlagbares Zwischenstück umfasst, das mit komplementären Schrägflächen der Lagerelemente zusammenwirkende Schrägflächen aufweist, so dass mit einer jeweiligen Beaufschlagung des Zwischenstücks durch eine mittels des Werkzeugs aufgebrachte Drückkraft und einer damit einhergehenden Verlagerung des Zwischenstücks relativ zu den Lagerelementen die beiden Lagerelemente und damit die beiden Bolzen zum Lösen der Rastverbindung und zur Freigabe des Endstücks des Kraftübertragungselements auseinanderpressbar sind.It is particularly advantageous if the release mechanism comprises an intermediate piece which is arranged between the two resiliently preloaded bearing elements, is displaceable perpendicular to the bearing elements and can be acted upon by the tool, which has inclined surfaces cooperating with complementary inclined surfaces of the bearing elements, so that when the Intermediate piece by a pressing force applied by means of the tool and an associated displacement of the intermediate piece relative to the bearing elements, the two bearing elements and thus the two bolts for releasing the locking connection and releasing the end piece of the force transmission element can be pressed apart.

Wie zuvor bereits erwähnt, können anstelle der Bolzen oder dergleichen auch beliebige andere Eingriffselemente vorgesehen sein.As mentioned above, any other engagement elements can also be provided instead of the bolts or the like.

Es ergibt sich somit eine im Aufbau einfach gehaltene, zuverlässige Auslösemechanik, mit der eine jeweilige mittels des Werkzeugs auf das Zwischenstück aufgebrachte Drückkraft dazu führt, dass die beiden Bolzen zum Lösen der Rastverbindung und zur Freigabe des Endstücks des Kraftübertragungselements auseinandergezogen werden.The result is a simple, reliable release mechanism with which a respective pressing force applied to the intermediate piece by means of the tool causes the two bolts to be pulled apart to release the latching connection and to release the end piece of the force transmission element.

Gemäß einer zweckmäßigen praktischen Ausführungsform des erfindungsgemäßen Antriebs sind die beiden Lagerelemente jeweils winkelartig ausgeführt und die Bolzen an einander gegenüberliegenden ersten Schenkeln der winkelartigen Lagerelemente fest abgestützt, während das Zwischenstück zwischen gegenüber den ersten Schenkeln zumindest im Wesentlichen senkrechten zweiten Schenkeln angeordnet ist. In diesem Fall können die mit den Schrägflächen des Zwischenstücks zusammenwirkenden komplementären Schrägflächen der Lagerelemente an deren zweiten Schenkeln vorgesehen sein.According to an expedient practical embodiment of the drive according to the invention, the two bearing elements are each designed angularly and the bolts are firmly supported on opposing first legs of the angular bearing elements, while the intermediate piece is arranged between second legs that are at least substantially perpendicular to the first legs. In this case, the complementary inclined surfaces of the bearing elements cooperating with the inclined surfaces of the intermediate piece can be provided on their second legs.

Von Vorteil ist insbesondere auch, wenn das Endstück des Kraftübertragungselements auf einander gegenüberliegenden Seiten mit komplementären Schrägflächen der Bolzen zusammenwirkende Schrägflächen aufweist, so dass mit einem jeweiligen Einsetzen des Endstücks des Kraftübertragungselements in den Kraftübertragungselement-Bock die beiden Bolzen entgegen den diese beaufschlagenden Federkräften zunächst auseinandergepresst werden, um anschließend durch die Federkräfte in das Endstück des Kraftübertragungselements einzurasten.It is particularly advantageous if the end piece of the force transmission element has inclined surfaces cooperating with complementary inclined surfaces of the bolts on opposite sides, so that when the end piece of the force transmission element is inserted into the force transmission element bracket, the two bolts are initially pressed apart against the spring forces acting on them in order to then snap into the end piece of the force transmission element by the spring forces.

Während die Bolzen nach einem Herausziehen des Werkzeugs nach erfolgter Auslösung der Rastverbindung und erfolgter Trennung des Endstücks des Kraftübertragungselements vom Kraftübertragungselement-Bock die beiden Bolzen infolge der sie beaufschlagenden Federkräfte automatisch wieder aufeinander zu bewegt werden, werden bei einem jeweiligen Einsetzen des Endstücks des Kraftübertragungselements in den Kraftübertragungselement-Bock bzw. einem jeweiligen Schließen des Fensters bzw. der Tür durch die zusammenwirkenden Schrägflächen des Kraftübertragungselements und der Bolzen die Bolzen entgegen der diese beaufschlagenden Federkräfte zunächst wieder auseinandergedrückt. Sobald das Endstück des Kraftübertragungselements seine Endposition im Kraftübertragungselement-Bock erreicht hat, rasten die Bolzen durch die sie beaufschlagenden Federkräfte automatisch in das Endstück ein, wodurch die Rastverbindung zwischen dem Endstück des Kraftübertragungselements und dem Kraftübertragungselement-Bock bzw. zwischen Flügel und Rahmen automatisch wiederhergestellt ist.While the bolts are automatically moved towards each other again as a result of the spring forces acting on them after the tool has been pulled out after the latching connection has been released and the end piece of the force transmission element has been separated from the force transmission element block, each time the end piece of the force transmission element is inserted into the Force transmission element block or a respective closing of the window or the door by the cooperating inclined surfaces of the force transmission element and the bolts, the bolts are initially pushed apart again against the spring forces acting on them. As soon as the end piece of the force transmission element has reached its end position in the force transmission element block, the bolts snap through the ones acting on them Spring forces automatically into the end piece, whereby the locking connection between the end piece of the power transmission element and the power transmission element block or between the sash and the frame is automatically restored.

Mit der erfindungsgemäßen Notentriegelung für integrierte Antriebe ist das Entriegeln ohne den bisher erforderlichen hohen Kraftaufwand sowie unter Vermeidung der bisher gegebenen Gefahr einer Beschädigung der des Fensters bzw. der Tür möglich. Zur Notentriegelung ist lediglich mittels eines Werkzeugs wie beispielsweise eines einfachen Schraubendrehers eine Drückkraft aufzubringen. Zudem kann das Fenster bzw. die Tür aufgrund der zusammenwirkenden Schrägflächen der Bolzen und des Endstücks einfach wieder zugedrückt werden, womit die Verbindung zwischen Endstück des Kraftübertragungselements und dem Kraftübertragungselement-Bock bzw. zwischen Flügel und Rahmen automatisch wiederhergestellt wird. Nach erfolgter Trennung der Kraftübertragungselement- bzw. Kettenverbindung ist somit eine Wartung des Antriebs und/oder ein Öffnen des Fensters bzw. der Tür sehr schnell und ohne aufwendige Montage möglich. Auch die Montage des Gesamtsystems wird vereinfacht. Der Kraftübertragungselement- bzw. Kettenbock wird eingebracht, und das Endstück des Kraftübertragungselements bzw. der Kette wird mit dem Kraftübertragungselement-Bock bzw. Kettenbock durch einfaches Zudrücken des Fensters bzw. der Tür verbunden.With the emergency release according to the invention for integrated drives, unlocking is possible without the high expenditure of force previously required and while avoiding the previously existing risk of damage to the window or door. For emergency unlocking, a pushing force only needs to be applied using a tool such as a simple screwdriver. In addition, the window or door can simply be pushed shut again due to the cooperating inclined surfaces of the bolts and the end piece, which automatically re-establishes the connection between the end piece of the force transmission element and the force transmission element block or between the sash and the frame. After the force transmission element or chain connection has been separated, maintenance of the drive and / or opening of the window or door is possible very quickly and without complex assembly. The assembly of the entire system is also simplified. The force transmission element or chain bracket is introduced and the end piece of the force transmission element or chain is connected to the force transmission element bracket or chain bracket by simply pressing the window or door shut.

Das erfindungsgemäße Fenster, Tür oder dergleichen zeichnet sich dadurch aus, dass es bzw. sie mit einem erfindungsgemäßen Antrieb versehen ist.The window, door or the like according to the invention is characterized in that it or they are provided with a drive according to the invention.

Dabei ist als Werkzeug 18 beispielsweise ein Schraubendreher oder dergleichen einsetzbar.The end piece 12 of the force transmission element can be fixed in the force transmission element block 14 via a latching connection 16 and the force transmission element block 14 is designed in such a way that the end piece 12 of the force transmission element is normally used both for motorized opening and closing of the sash and when the sash is closed Locking connection 16 can be fixed in the power transmission element bracket 14 and the locking connection 16 can be released manually from the outside by applying a pressure F using a tool 18 which can be passed through an opening provided in the wing profile to release the end piece 12 of the power transmission element in an emergency with the wing closed.

Grundsätzlich ist jedoch auch eine solche Ausführung denkbar, bei der das Endstück 12 des Kraftübertragungselements auf einander gegenüberliegenden Seiten jeweils mit einer getrennten Öffnung 24 versehen ist, in die jeweils ein Bolzen 20 einrastbar ist.The end piece 12 of the power transmission element can be provided with a through opening 24 into which the two bolts 20 from opposite sides Ends can be locked in place. In principle, however, such an embodiment is also conceivable in which the end piece 12 of the force transmission element is provided with a separate opening 24 on opposite sides, into which a bolt 20 can be latched.

Der Kraftübertragungselement-Bock 14 ist mit einer Auslösemechanik 26 versehen, über die mit einer jeweiligen Beaufschlagung durch eine mittels des Werkzeugs 18 aufgebrachte Drückkraft F die federnd aufeinander zu vorbelasteten Bolzen 20 zum Lösen der Rastverbindung 16 und zur Freigabe des Endstücks 12 des Kraftübertragungselements entgegen der Federkräfte auseinanderpressbar sind.The force transmission element bracket 14 is provided with a release mechanism 26 via which, with a respective loading by a pressing force F applied by means of the tool 18, the bolts 20, which are resiliently preloaded towards one another, for releasing the latching connection 16 and for releasing the end piece 12 of the force transmission element against the spring forces are squeezable.

Dabei umfasst die Auslösemechanik 26 des Kraftübertragungselement-Bocks 14 im vorliegenden Fall zwei einander gegenüberliegende, jeweils axial verschiebbar im Kraftübertragungselement-Bock 14 gelagerte, federnd aufeinander zu vorbelastete und den Aufnahmebereich 22 seitlich begrenzende Lagerelemente 28, an denen jeweils einer der beiden Bolzen 20 fest abgestützt ist und über die die Bolzen 20 federnd aufeinander zu vorbelastet sind.In the present case, the release mechanism 26 of the force transmission element block 14 comprises two opposing bearing elements 28, each axially displaceable in the force transmission element block 14, resiliently preloaded towards one another and laterally delimiting the receiving area 22, on each of which one of the two bolts 20 is firmly supported is and via which the bolts 20 are resiliently preloaded towards one another.
