Description

Die Erfindung betrifft einen Verriegelungsantrieb zum Verriegeln und Entriegeln eines Flügels eines Fensters, einer Tür oder dergleichen mit einer motorischen Antriebseinheit. Derartige Verriegelungsantriebe sind zum Beispiel aus EP 2 711 490 A1 oder EP 1 083 281 A2 bekannt.The invention relates to a locking drive for locking and unlocking a sash of a window, a door or the like with a motorized drive unit. Such locking drives are for example from EP 2 711 490 A1 or EP 1 083 281 A2 known.

Über einen solchen Verriegelungsantrieb ist der betreffende Fenster- bzw. Türflügel über einen diesem zugeordneten Verriegelungsbeschlag automatisch verriegelbar und entriegelbar, womit eine jeweilige Betätigung des Verriegelungsbeschlags entsprechend vereinfacht wird.The relevant window or door sash can be automatically locked and unlocked via a locking fitting assigned to it via such a locking drive, whereby a respective actuation of the locking fitting is correspondingly simplified.

Die bisher üblichen Verriegelungsantriebe der eingangs genannten Art weisen nun aber den Nachteil auf, dass, nachdem der Verriegelungs- bzw. Entriegelungsvorgang relativ schnell vonstattengehen soll, die dazu erforderliche Bewegungsgeschwindigkeit des motorischen Antriebs relativ hoch sein muss, was nun aber entsprechende Geräusche mit sich bringt, die umso störender sind, je schneller sich die motorische Antriebseinheit bewegt.The previously common locking drives of the type mentioned above now have the disadvantage that, after the locking or unlocking process is to take place relatively quickly, the required movement speed of the motor drive must be relatively high, which now brings with it corresponding noises, which are all the more disruptive the faster the motor drive unit moves.

Der Erfindung liegt die Aufgabe zugrunde, einen Verriegelungsantrieb der eingangs genannten Art anzugeben, mit dem ein unmittelbares automatisches Verriegeln und Entriegeln des Fenster- bzw. Türflügels innerhalb möglichst kurzer Zeit bei möglichst geringer Geräuschentwicklung ermöglicht wird.The invention is based on the object of specifying a locking drive of the type mentioned at the beginning, with which a direct automatic locking and unlocking of the window or door leaf is made possible within the shortest possible time with the lowest possible noise development.

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

Der erfindungsgemäße Verriegelungsantrieb zum Verriegeln und Entriegeln eines Flügels eines Fensters, einer Tür oder dergleichen umfasst eine motorische Antriebseinheit, einen über die motorische Antriebseinheit vorladbaren, zum Verriegeln des Flügels mit einem diesem zugeordneten Verriegelungsbeschlag koppelbaren, insbesondere mechanischen Verriegelungs-Energiespeicher, einen über die motorische Antriebseinheit vorladbaren, zum Entriegeln des Flügels mit dem Verriegelungsbeschlag koppelbaren, insbesondere mechanischen Entriegelungs-Energiespeicher und eine Steuerungseinrichtung. Dabei ist über die Steuerungseinrichtung die motorische Antriebseinheit so ansteuerbar und die Entladung eines jeweiligen vorgeladenen Energiespeichers so auslösbar, dass zur Verriegelung des Flügels bei stillstehender motorischer Antriebseinheit durch die im vorgeladenen Verriegelungs-Energiespeicher gespeicherte Energie zunächst die Entladung des vorgeladenen Verriegelungs-Energiespeichers ausgelöst und erst nach erfolgter Verriegelung der Entriegelungs-Energiespeicher durch die motorische Antriebseinheit vorgeladen wird, und zur Entriegelung des Flügels bei stillstehender motorischer Antriebseinheit durch die im vorgeladenen Entriegelungs-Energiespeicher gespeicherter Energie zunächst die Entladung des vorgeladenen Entriegelungs-Energiespeichers ausgelöst und erst nach erfolgter Entriegelung der Verriegelungs-Energiespeicher durch die motorische Antriebseinheit vorgeladen wird.The locking drive according to the invention for locking and unlocking a sash of a window, a door or the like comprises a motorized drive unit, an in particular mechanical locking energy storage device which can be preloaded via the motorized drive unit and can be coupled to a locking fitting associated therewith for locking the sash, and an in particular mechanical locking energy store Pre-loadable, in particular mechanical unlocking energy storage devices that can be coupled to the locking fitting for unlocking the sash, and a control device. The motorized drive unit can be controlled via the control device and the discharge of a respective precharged energy storage device can be triggered in such a way that, in order to lock the sash when the motorized drive unit is at a standstill, the energy stored in the precharged locking energy storage device initially triggers the discharge of the precharged locking energy storage device and only after After locking the unlocking energy store is precharged by the motorized drive unit, and for unlocking the sash when the motorized drive unit is at a standstill, the energy stored in the precharged unlocking energy store first triggers the discharge of the precharged unlocking energy store and only after the locking energy store has been unlocked the motor drive unit is preloaded.

Aufgrund dieser Ausbildung ist mit dem Verriegelungsantrieb jeweils ein unmittelbares automatisches Verriegeln und Entriegeln des Fenster- bzw. Türflügels innerhalb sehr kurzer Zeit bei auf ein Minimum reduzierter Geräuschentwicklung gewährleistet. So erfolgt bei einem jeweiligen Verriegelungs- bzw. Entriegelungsvorgang für das betreffende Verriegeln bzw. Entriegeln des Fenster- bzw. Türflügels zunächst eine entsprechende Betätigung des diesem zugeordneten Verriegelungsbeschlags durch die in einem jeweiligen Energiespeicher gespeicherte Energie. Erst anschließend wird durch die motorische Antriebseinheit der später zum Entriegeln bzw. Verriegeln benötigte weitere Energiespeicher durch den motorischen Antrieb wieder vorgeladen. Das Vorladen des weiteren Energiespeichers kann ohne jeglichen Zeitdruck erfolgen, da die vom Benutzer jeweils geforderte Aktion, d.h. das eigentliche Verriegeln bzw. Entriegeln, bereits ausgeführt ist. Für ein solches Vorladen eines jeweiligen Energiespeichers kann die motorische Antriebseinheit somit mit relativ geringer Geschwindigkeit betrieben werden, wodurch die betreffende Geräuschentwicklung auf ein Minimum reduziert wird. Gleichzeitig ergeben sich für den jeweiligen Benutzer sehr geringe Wartezeiten, nachdem das eigentliche Verriegeln bzw. Entriegeln des Fenster- bzw. Türflügels durch die gespeicherte Energie des betreffenden Energiespeichers innerhalb sehr kurzer Zeit und insbesondere innerhalb weniger als einer Sekunde erfolgt.Due to this design, a direct automatic locking and unlocking of the window or door sash is guaranteed with the locking drive within a very short time with a minimum of noise. Thus, in a respective locking or unlocking process for the relevant locking or unlocking of the window or door sash, a corresponding actuation of the locking fitting assigned to it is initially carried out by the energy stored in a respective energy store. Only then is the motorized drive unit precharged the further energy storage device later required for unlocking or locking by the motorized drive. The pre-charging of the further energy storage can take place without any time pressure, since the action requested by the user, ie the actual locking or unlocking, has already been carried out. For such a pre-charging of a respective energy store, the motorized drive unit can thus be operated at a relatively low speed, as a result of which the relevant noise development is reduced to a minimum. At the same time, there are very short waiting times for the respective user after the actual locking or unlocking of the window or door sash takes place within a very short time and in particular within less than a second using the stored energy of the relevant energy store.

Im Vergleich zu einer Betätigung über einen gewöhnlichen Fenstergriff wird das Verriegeln bzw. Entriegeln somit durch die automatische Betätigung nicht nur vereinfacht, sondern auch wesentlich beschleunigt, ohne dass dabei störende Geräusche entstehen.In comparison to actuation via a conventional window handle, locking or unlocking is thus not only simplified by the automatic actuation, but also significantly accelerated, without disturbing noises being produced.

Bevorzugt umfasst der Verriegelungs-Energiespeicher eine durch die motorische Antriebseinheit vorspannbare Verriegelungs-Federeinheit und/oder der Entriegelungs-Energiespeicher eine durch die motorische Antriebseinheit vorspannbare Entriegelungs-Federeinheit.The locking energy store preferably comprises a locking spring unit that can be preloaded by the motorized drive unit and / or the unlocking energy store comprises an unlocking spring unit that can be preloaded by the motorized drive unit.

Die eigentliche Verriegelung bzw. Entriegelung des Fenster-Türflügels erfolgt in diesem Fall durch die Energie einer durch die motorische Antriebseinheit vorspannbaren Verriegelungs-Federeinheit bzw. durch die Energie einer durch die motorische Antriebseinheit vorspannbaren Entriegelungs-Federeinheit.The actual locking or unlocking of the window-door sash takes place in this case by the energy of a locking spring unit that can be prestressed by the motor drive unit or by the energy of an unlocking spring unit that can be prestressed by the motor drive unit.

Von Vorteil ist insbesondere auch, wenn die motorische Antriebseinheit einen Linearantrieb umfasst.It is also particularly advantageous if the motorized drive unit comprises a linear drive.

Mit einem solchen Linearantrieb kann ein jeweiliger mechanischer Energiespeicher bzw. Federeinheit über eine lineare Bewegung des Antriebs vorgeladen werden, womit der Verriegelungsantrieb im Aufbau relativ einfach gehalten werden kann.With such a linear drive, a respective mechanical energy store or spring unit can be precharged via a linear movement of the drive, so that the locking drive can be kept relatively simple in structure.

Gemäß einer bevorzugten praktischen Ausführungsform umfasst der Verriegelungsantrieb einen mit dem Verriegelungsbeschlag verbindbaren oder verbundenen Schlitten, der zwischen einer Verriegelungsposition und einer Entriegelungsposition verschiebbar gelagert ist, in denen er durch eine Feststellvorrichtung jeweils feststellbar und durch den vorgeladenen Entriegelungs-Energiespeicher bzw. den vorgeladenen Verriegelungs-Energiespeicher beaufschlagbar ist.According to a preferred practical embodiment, the locking drive comprises a slide which can be or is connected to the locking fitting and which is mounted displaceably between a locking position and an unlocking position, in which it can be locked by a locking device and by the precharged unlocking energy store or the precharged locking energy store can be acted upon.

Sobald der Schlitten nach erfolgter Verriegelung oder Entriegelung in der Verriegelungsposition bzw. Entriegelungsposition festgestellt ist, kann somit durch die motorische Antriebseinheit der für den anschließenden Entriegelungs- bzw. Verriegelungsvorgang erforderliche Energiespeicher gegen den Schlitten vorgeladen bzw. vorgespannt werden.As soon as the slide is locked in the locked or unlocked position after locking or unlocking, the energy store required for the subsequent unlocking or locking process can be preloaded or preloaded against the slide by the motor drive unit.

Die Feststellvorrichtung ist durch die Steuerungseinrichtung bevorzugt so ansteuerbar, dass der seine Verriegelungsposition einnehmende, durch den vorgeladenen Entriegelungs-Energiespeicher beaufschlagte Schlitten zur Entriegelung des Flügels freigegeben wird, um bei stillstehender motorischer Antriebseinheit durch den sich entladenden Entriegelungs-Energiespeicher in seine Entriegelungsposition verschoben zu werden.The locking device is preferably controllable by the control device in such a way that the slide, which occupies its locking position and is acted upon by the precharged unlocking energy store, is released for unlocking the sash, in order to be moved into its unlocking position by the unloading unlocking energy store when the motorized drive unit is stationary.

Vorteilhafterweise stützt sich dabei der zur Verschiebung des Schlittens in dessen Entriegelungsposition entladende Entriegelungs-Energiespeicher bzw. Entriegelungs-Federeinheit einerseits am Schlitten ab, während er andererseits bei stillstehender motorischer Antriebseinheit fest abgestützt ist.Advantageously, the unlocking energy store or unlocking spring unit, which is discharged to move the carriage into its unlocking position, is supported on the one hand on the carriage, while on the other hand it is firmly supported when the motorized drive unit is stationary.

Zudem ist die Feststellvorrichtung durch die Steuerungseinrichtung vorteilhafterweise so ansteuerbar, dass der Schlitten nach seiner Überführung aus seiner Verriegelungsposition in seine Entriegelungsposition in seiner Entriegelungsposition wieder festgestellt wird.In addition, the locking device can advantageously be controlled by the control device in such a way that the slide is moved out of its locking position in its unlocked position is determined again in its unlocked position.

Dabei ist die motorische Antriebseinheit durch die Steuerungseinheit bevorzugt so ansteuerbar, dass sie den Verriegelungs-Energiespeicher nach der Überführung des Schlittens in seine Entriegelungsposition und nach erfolgter Feststellung in diese Entriegelungsposition zur Beaufschlagung des Schlittens wieder vorlädt.The motorized drive unit can preferably be controlled by the control unit in such a way that it preloads the locking energy store again after the carriage has been moved into its unlocked position and after it has been determined in this unlocked position to act on the carriage.

Darüber hinaus ist die Feststellvorrichtung durch die Steuerungseinrichtung bevorzugt so ansteuerbar, dass der seine Entriegelungsposition einnehmende, durch den vorgeladenen Verriegelungs-Energiespeicher beaufschlagte Schlitten zur Verriegelung des Flügels freigegeben wird, um bei stillstehender motorischer Antriebseinheit durch den sich entladenden Verriegelungs-Energiespeicher in seine Verriegelungsposition verschoben zu werden.In addition, the locking device can preferably be controlled by the control device in such a way that the slide, which occupies its unlocking position and is acted upon by the precharged locking energy store, is released for locking the sash in order to be moved into its locking position by the discharging locking energy store when the motorized drive unit is stationary will.

Vorteilhafterweise stützt sich der sich zur Verschiebung des Schlittens in dessen Verriegelungsposition entladende Verriegelungs-Energiespeicher bzw. Verriegelungs-Federeinheit einerseits am Schlitten ab, während er andererseits bei stillstehender motorischer Antriebseinheit fest abgestützt ist.The locking energy store or locking spring unit, which is discharged to move the slide into its locking position, is advantageously supported on the one hand on the slide, while on the other hand it is firmly supported when the motorized drive unit is stationary.

Vorteilhafterweise ist die Feststellvorrichtung durch die Steuerungseinrichtung so ansteuerbar, dass der Schlitten nach seiner Überführung aus seiner Entriegelungsposition in seine Verriegelungsposition in seiner Verriegelungsposition wieder festgestellt wird.The locking device can advantageously be controlled by the control device in such a way that the slide is locked again in its locking position after it has been transferred from its unlocking position to its locking position.

Dabei ist die motorische Antriebseinheit durch die Steuerungseinrichtung bevorzugt so ansteuerbar, dass sie den Entriegelungs-Energiespeicher nach der Überführung des Schlittens in seine Verriegelungsposition und nach erfolgter Feststellung in dieser Verriegelungsposition zur Beaufschlagung des Schlittens wieder vorlädt.The motorized drive unit can preferably be controlled by the control device in such a way that it preloads the unlocking energy store again after the carriage has been transferred into its locking position and after it has been locked in this locking position to act on the carriage.

Gemäß einer zweckmäßigen praktischen Ausführungsform des erfindungsgemäßen Verriegelungsantriebs sind der Verriegelungs-Energiespeicher und der Entriegelungs-Energiespeicher über einen durch die motorische Antriebseinheit insbesondere linear verschiebbaren Bügel oder dergleichen jeweils gegen den festgestellten Schlitten vorspannbar.According to an expedient practical embodiment of the locking drive according to the invention, the locking energy store and the unlocking energy store can each be preloaded against the fixed slide via a bracket or the like that can be moved linearly by the motorized drive unit.

Mit einem solchen Bügel, über den durch die motorische Antriebseinheit sowohl der Verriegelungs-Energiespeicher als auch der Entriegelungs-Energiespeicher beaufschlagbar bzw. vorspannbar sind, ist wiederum ein relativ einfach gehaltener Aufbau des Verriegelungsantriebs möglich.With such a bracket, via which both the locking energy store and the unlocking energy store can be acted upon or preloaded by the motorized drive unit, a relatively simple construction of the locking drive is again possible.

Bevorzugt ist dabei der Schlitten bei stillstehender motorischer Antriebseinheit und insbesondere durch die Feststellvorrichtung festgestelltem Bügel durch den sich entladenden, einerseits am Schlitten und andererseits am festgestellten Bügel abgestützten Entriegelungs-Energiespeicher relativ zum festgestellten Bügel aus seiner Verriegelungsposition in seine Entriegelungsposition und durch den sich entladenden, einerseits am Schlitten und andererseits am festgestellten Bügel abgestützten Verriegelungs-Energiespeicher relativ zum festgestellten Bügel aus seiner Entriegelungsposition in seine Verriegelungsposition verschiebbar.In this case, the carriage is preferred when the motorized drive unit is at a standstill and in particular by the bracket fixed by the locking device by the unloading unlocking energy store supported on the one hand on the carriage and on the other hand on the fixed bracket relative to the fixed bracket from its locking position to its unlocking position and by the discharging, on the one hand on the slide and on the other hand on the fixed bracket supported locking energy store relative to the fixed bracket from its unlocked position into its locking position.

Von Vorteil ist insbesondere, wenn der Bügel mit zwei einander gegenüberliegenden Randabschnitten versehen ist, zwischen denen der insbesondere eine Entriegelungs-Federeinheit umfassende Entriegelungs-Energiespeicher, der insbesondere eine Verriegelungs-Federeinheit umfassende Verriegelungs-Energiespeicher und der dazwischenliegende Schlitten angeordnet sind, wobei der Entriegelungs-Energiespeicher mit seinem vom Schlitten abgewandten Ende an einem der beiden Randabschnitte abgestützt und insbesondere fest mit diesem verbunden und der Verriegelungs-Energiespeicher mit seinem vom Schlitten abgewandten Ende an dem anderen Randabschnitt abgestützt und insbesondere fest mit diesem verbunden ist.It is particularly advantageous if the bracket is provided with two mutually opposite edge sections, between which the unlocking energy store, in particular comprising an unlocking spring unit, the locking energy store, in particular comprising a locking spring unit, and the slide lying in between are arranged, the unlocking Energy store with its end facing away from the slide supported on one of the two edge sections and in particular firmly connected to this, and the locking energy store with its end facing away from the slide is supported on the other edge portion and in particular is firmly connected to this.

Die Fig. 1 bis 5 zeigen unterschiedliche Zustände einer beispielhaften Ausführungsform eines erfindungsgemäßen Verriegelungsantriebs 10 zum Verriegeln und Entriegeln eines Flügels eines Fensters, einer Tür oder dergleichen.The Figs. 1 to 5 show different states of an exemplary embodiment of a locking drive 10 according to the invention for locking and unlocking a sash of a window, a door or the like.

Der Verriegelungsantrieb 10 umfasst eine motorische Antriebseinheit 12, einen über die motorische Antriebseinheit 12 vorladbaren, zum Verriegeln des Flügels mit einem diesem zugeordneten Verriegelungsbeschlag koppelbaren, insbesondere mechanischen Verriegelungs-Energiespeicher 14, hier beispielsweise eine Verriegelungs-Federeinheit, einen über die motorische Antriebseinheit 12 vorladbaren, zum Entriegeln des Flügels mit dem Verriegelungs-Beschlag koppelbaren, insbesondere mechanischen Entriegelungs-Energiespeicher 16, im vorliegenden Fall beispielsweise eine Entriegelungs-Federeinheit, und eine Steuerungseinrichtung 18.The locking drive 10 comprises a motorized drive unit 12, an in particular mechanical locking energy store 14 that can be preloaded via the motorized drive unit 12 and can be coupled to a locking fitting associated therewith for locking the sash, here for example a locking spring unit, one that can be preloaded via the motorized drive unit 12, for unlocking the sash with the locking fitting, in particular mechanical unlocking energy storage 16, in the present case for example an unlocking spring unit, and a control device 18.

Dabei sind über die Steuerungseinrichtung 18 die motorische Antriebseinheit 12 so ansteuerbar und die Entladung eines jeweiligen vorgeladenen Energiespeichers 14, 16 bzw. Federeinheit so auslösbar, dass zur Verriegelung des Flügels bei stillstehender motorischer Antriebseinheit 12 durch die im vorgeladenen Verriegelungs-Energiespeicher 14 gespeicherte Energie zunächst die Entladung des vorgeladenen Verriegelungs-Energiespeichers 14 ausgelöst und erst nach erfolgter Verriegelung der Entriegelungs-Energiespeicher 16 durch die motorische Antriebseinheit 12 vorgeladen wird (vgl. insbesondere die Fig. 3 bis 5), und zur Entriegelung des Flügels bei stillstehender motorischer Antriebseinheit 12 durch die im vorgeladenen Entriegelungs-Energiespeicher 16 gespeicherte Energie zunächst die Entladung des vorgeladenen Entriegelungs-Energiespeichers ausgelöst und erst nach erfolgter Entriegelung der Verriegelungs-Energiespeicher durch die motorische Antriebseinheit 12 vorgeladen wird (vgl. insbesondere die Fig. 1 bis 3).The motor drive unit 12 can be controlled via the control device 18 and the discharge of a respective precharged energy store 14, 16 or spring unit can be triggered in such a way that the energy stored in the precharged locking energy store 14 is initially used to lock the wing when the motor drive unit 12 is stationary Discharge of the precharged locking energy store 14 triggered and only after locking of the unlocking energy store 16 by the motor drive unit 12 is summoned (see in particular the Figs. 3 to 5 ), and for unlocking the sash with the motorized drive unit 12 at a standstill, the energy stored in the precharged unlocking energy store 16 first triggers the discharge of the precharged unlocking energy store and is only precharged by the motorized drive unit 12 after the locking energy store has been unlocked (cf. especially the Figs. 1 to 3 ).

Wie bereits ausgeführt, umfasst beim vorliegenden Ausführungsbeispiel der Verriegelungs-Energiespeicher 14 eine durch die motorische Antriebseinheit 12 vorspannbare Verriegelungs-Federeinheit und der Entriegelungs-Energiespeicher 16 eine durch die motorische Antriebseinheit 12 vorspannbare Entriegelungs-Federeinheit.As already stated, in the present exemplary embodiment the locking energy store 14 comprises a locking spring unit that can be preloaded by the motorized drive unit 12 and the unlocking energy store 16 comprises an unlocking spring unit that can be preloaded by the motorized drive unit 12.

Die Antriebseinheit 12 umfasst im vorliegenden Fall beispielsweise einen Linearantrieb.In the present case, the drive unit 12 comprises, for example, a linear drive.

Zudem umfasst der Verriegelungsantrieb 10 einen mit dem Verriegelungsbeschlag des betreffenden Fenster- oder Türflügels verbindbaren oder verbundenen Schlitten 20, der zwischen einer Verriegelungsposition (vgl. die Fig. 1, 4 und 5) und einer Entriegelungsposition (vgl. die Fig. 2 und 3) verschiebbar gelagert ist, in denen er durch eine Feststellvorrichtung jeweils feststellbar und durch den vorgeladenen Entriegelungs-Energiespeicher 16 bzw. den vorgeladenen Verriegelungs-Energiespeicher 14 beaufschlagbar ist.In addition, the locking drive 10 comprises a slide 20 which can be or is connected to the locking fitting of the relevant window or door sash, which slide between a locking position (cf. Fig. 1 , 4 and 5 ) and an unlocking position (see Figs. 2 and 3 ) is displaceably mounted, in which it can be locked by a locking device and acted upon by the precharged unlocking energy store 16 or the precharged locking energy store 14.

Die Feststellvorrichtung 22 ist durch die Steuerungseinrichtung 18 so ansteuerbar, dass der seine Verriegelungsposition einnehmende, durch den vorgeladenen Entriegelungs-Energiespeicher 16 beaufschlagte Schlitten 20 zur Entriegelung des Flügels freigegeben wird, um bei stillstehender motorischer Antriebseinheit 12 durch den sich entladenden Entriegelungs-Energiespeicher 16 in seine Entriegelungsposition verschoben zu werden (vgl. insbesondere die Fig. 1 und 2).The locking device 22 can be controlled by the control device 18 in such a way that the slide 20, which is in its locking position and acted upon by the precharged unlocking energy store 16, is released for unlocking the sash, so that when the motorized drive unit 12 is at a standstill, it can be moved into its locking position by the unlocking energy store 16 To be moved unlocking position (see in particular the Figs. 1 and 2 ).

Dabei ist der sich zur Verschiebung des Schlittens 20 in dessen Entriegelungsposition entladende Entriegelungs-Energiespeicher 16 bzw. Entriegelungs-Federeinheit einerseits am Schlitten 20 abgestützt, während er andererseits bei stillstehender motorischer Antriebseinheit 12 fest abgestützt ist (vgl. insbesondere nochmals die Fig. 1 und 2).The unlocking energy store 16 or unlocking spring unit, which is discharged to move the carriage 20 into its unlocking position, is supported on the one hand on the carriage 20, while on the other hand it is firmly supported when the motorized drive unit 12 is at a standstill (cf. in particular again the Figs. 1 and 2 ).

Zudem ist die Feststellvorrichtung 22 durch die Steuerungseinrichtung 18 so ansteuerbar, dass der Schlitten 20 nach seiner Überführung aus seiner Verriegelungsposition in seine Entriegelungsposition in seiner Entriegelungsposition wieder festgestellt wird (vgl. insbesondere Fig. 2).In addition, the locking device 22 can be controlled by the control device 18 in such a way that the slide 20 is locked again in its unlocking position after it has been transferred from its locking position to its unlocking position (cf. in particular Fig. 2 ).

Dabei ist die motorische Antriebseinheit 12 durch die Steuerungseinrichtung 18 so ansteuerbar, dass sie den Verriegelungs-Energiespeicher 14 nach der Überführung des Schlittens 20 in seine Entriegelungsposition und nach erfolgter Feststellung in dieser Entriegelungsposition zur Beaufschlagung des Schlittens 20 wieder vorlädt (vgl. insbesondere die Fig. 2 und 3).The motor drive unit 12 can be controlled by the control device 18 in such a way that it preloads the locking energy store 14 again after the carriage 20 has been moved into its unlocking position and after it has been determined in this unlocking position to act on the carriage 20 (see in particular the Figs. 2 and 3 ).

Die Feststellvorrichtung 22 ist durch die Steuerungseinrichtung 18 zudem so ansteuerbar, dass der seine Entriegelungsposition einnehmende, durch den vorgeladenen Verriegelungs-Energiespeicher 14 beaufschlagte Schlitten 20 zur Verriegelung des Flügels freigegeben wird, um bei stillstehender motorischer Antriebseinheit 12 durch den sich entladenden Verriegelungs-Energiespeicher 14 in seine Verriegelungsposition verschoben zu werden (vgl. insbesondere die Fig. 3 und 4).The locking device 22 can also be controlled by the control device 18 in such a way that the slide 20, which is in its unlocked position and acted upon by the precharged locking energy store 14, is released for locking the sash, so that when the motorized drive unit 12 is at a standstill, the locking energy store 14 is discharged its locking position to be shifted (see in particular the Fig. 3 and 4th ).

Dabei stützt der sich zur Verschiebung des Schlittens 20 in dessen Verriegelungsposition entladende Verriegelungs-Energiespeicher 14 bzw. Verriegelungs-Federeinheit sich einerseits am Schlitten 20 ab, während er andererseits bei stillstehender motorsicher Antriebseinheit 12 fest abgestützt ist.The locking energy store 14 or locking spring unit, which is discharged to move the slide 20 into its locking position, is supported on the one hand on the slide 20, while on the other hand it is firmly supported when the motor-safe drive unit 12 is at a standstill.

Die Feststellvorrichtung 22 ist durch die Steuerungseinrichtung 18 zudem so ansteuerbar, dass der Schlitten 20 nach seiner Überprüfung aus seiner Entriegelungsposition in seine Verriegelungsposition in seiner Verriegelungsposition wieder festgestellt wird (vgl. insbesondere Fig. 4).The locking device 22 can also be controlled by the control device 18 in such a way that the carriage 20 is locked again in its locking position after it has been checked from its unlocking position to its locking position (cf. in particular Fig. 4 ).

Die motorische Antriebseinheit 12 ist durch die Steuerungseinrichtung 18 so ansteuerbar, dass sie den Entriegelungs-Energiespeicher 16 nach der Überführung des Schlittens 20 in seine Verriegelungsposition und nach erfolgter Feststellung in dieser Verriegelungsposition zur Beaufschlagung des Schlittens 20 wieder vorlädt (vgl. insbesondere die Fig. 4 und 5).The motor drive unit 12 can be controlled by the control device 18 in such a way that it preloads the unlocking energy store 16 again after the carriage 20 has been moved into its locking position and after it has been locked in this locking position to act on the carriage 20 (see in particular the Figures 4 and 5 ).

Wie aus den Fig. 1 bis 5 ersichtlich, können der Verriegelungs-Energiespeicher 14 und der Entriegelungs-Energiespeicher 16 beispielsweise über einen durch die motorische Antriebseinheit 12 insbesondere linear verschiebbaren Bügel 24 oder dergleichen jeweils gegen den festgestellten Schlitten 20 vorspannbar sein.As from the Figs. 1 to 5 As can be seen, the locking energy store 14 and the unlocking energy store 16 can each be pretensioned against the fixed slide 20, for example, via a bracket 24 or the like that can be displaced in particular linearly by the motor drive unit 12.

Dabei ist der Schlitten 20 bei stillstehender motorischer Antriebseinheit 12 und insbesondere durch die Feststellvorrichtung 22 festgestelltem Bügel 24 durch den sich entladenden, einerseits am Schlitten 20 und andererseits am festgestellten Bügel 24 abgestützten Entriegelungs-Energiespeicher 16 relativ zum festgestellten Bügel 24 aus seiner Verriegelungsposition in seine Entriegelungsposition (vgl. insbesondere die Fig. 1 und 2) und durch den sich entladenden, einerseits am Schlitten 20 und andererseits am festgestellten Bügel 24 abgestützten Verriegelungs-Energiespeicher 14 relativ zum festgestellten Bügel 24 aus seiner Entriegelungsposition in seine Verriegelungsposition verschiebbar (vgl. insbesondere die Fig. 3 und 4).With the motorized drive unit 12 at a standstill and, in particular, with the bracket 24 fixed by the locking device 22, the carriage 20 is moved from its locking position into its unlocking position relative to the fixed bracket 24 by the unloading unlocking energy store 16 supported on the one hand on the carriage 20 and on the other on the fixed bracket 24 (see in particular the Figs. 1 and 2 ) and by the unloading, on the one hand on the carriage 20 and on the other hand on the fixed bracket 24 supported locking energy store 14 relative to the fixed bracket 24 from its unlocking position into its locking position (see in particular the Fig. 3 and 4th ).

Wie aus den Fig. 1 bis 5 weiter ersichtlich, ist der Bügel 24 im vorliegenden Fall beispielsweise mit zwei einander gegenüberliegenden Randabschnitten 26, 28 versehen, zwischen denen der insbesondere eine Entriegelungs-Federeinheit umfassende Entriegelungs-Energiespeicher 16, der insbesondere eine Verriegelungs-Federeinheit umfassende Verriegelungs-Energiespeicher 14 und der dazwischen liegende Schlitten 20 angeordnet sind. Dabei ist der Entriegelungs-Energiespeicher 16 mit seinem vom Schlitten 20 abgewandten Ende an einem der beiden Randabschnitte 26 abgestützt und insbesondere fest mit diesem verbunden, während der Verriegelungs-Energiespeicher 14 mit seinem vom Schlitten 20 abgestützten Ende an dem anderen Randabschnitt 28 abgestützt und insbesondere fest mit diesem verbunden ist.As from the Figs. 1 to 5 It can also be seen that in the present case the bracket 24 is provided, for example, with two mutually opposite edge sections 26, 28, between which the in particular one comprising an unlocking spring unit Unlocking energy store 16, the locking energy store 14 comprising, in particular, a locking spring unit and the slide 20 lying in between are arranged. The unlocking energy store 16 is supported with its end facing away from the slide 20 on one of the two edge sections 26 and in particular firmly connected to it, while the locking energy store 14 with its end supported by the slide 20 is supported and in particular firmly on the other edge section 28 is connected to this.

Der Verriegelungsantrieb ist mit einem Gehäuse 30 versehen, in dem die motorische Antriebseinheit 12, die Energiespeicher 14, 16, der Schlitten 20 und der Bügel 26 angeordnet sind. Die Steuerungseinrichtung 18 kann ebenfalls innerhalb des Gehäuses 30 oder auch außerhalb des Gehäuses 30 vorgesehen sein.The locking drive is provided with a housing 30 in which the motor drive unit 12, the energy stores 14, 16, the carriage 20 and the bracket 26 are arranged. The control device 18 can likewise be provided inside the housing 30 or also outside the housing 30.

Die Fig. 1 bis 5 zeigen unterschiedliche Zustände des Verriegelungsantriebs 10, wobei mit dem jeweiligen der motorischen Antriebseinheit 12 zugeordneten Pfeil die Bewegungsrichtung des motorischen Antriebs angedeutet ist.The Figs. 1 to 5 show different states of the locking drive 10, the direction of movement of the motor drive being indicated by the respective arrow assigned to the motor drive unit 12.

Dabei ist in der Darstellung gemäß Fig. 1 der Schlitten 20 in seiner Verriegelungsposition festgestellt, der Entriegelungs-Energiespeicher 16 bzw. die Entriegelungs-Federeinheit gegen den Schlitten 20 vorgeladen bzw. vorgespannt und der Verriegelungs-Energiespeicher 14 bzw. die Verriegelungs-Federeinheit entladen bzw. entspannt.It is in the representation according to Fig. 1 the slide 20 is fixed in its locking position, the unlocking energy store 16 or the unlocking spring unit is preloaded or pretensioned against the slide 20 and the locking energy store 14 or the locking spring unit is discharged or relaxed.

In der Darstellung gemäß Fig. 2 ist der Schlitten 20 in seiner Entriegelungsposition festgestellt und sowohl der Entriegelungs-Energiespeicher 16 bzw. die Entriegelungs-Federeinheit als auch der Verriegelungs-Energiespeicher 14 bzw. die Verriegelungs-Federeinheit jeweils entladen bzw. entspannt.In the representation according to Fig. 2 the carriage 20 is fixed in its unlocking position and both the unlocking energy store 16 or the unlocking spring unit and the locking energy store 14 or the locking spring unit are each discharged or relaxed.

In der Darstellung gemäß Fig. 3 ist der Schlitten 20 in seiner Entriegelungsposition festgestellt, während der Verriegelungs-Energiespeicher 14 bzw. die Verriegelungs-Federeinheit durch die motorische Antriebseinheit 12 gegen den festgestellten Schlitten 20 vorgeladen bzw. vorgespannt wird.In the representation according to Fig. 3 the slide 20 is locked in its unlocked position, while the locking energy store 14 or the locking spring unit is preloaded or pretensioned against the locked slide 20 by the motor drive unit 12.

In der Darstellung gemäß Fig. 4 ist der Schlitten 20 in seiner Verriegelungsposition festgestellt, während sowohl der Entriegelungs-Energiespeicher 16 bzw. die Entriegelungs-Federeinheit als auch der Verriegelungs-Energiespeicher 14 bzw. die Verriegelungs-Federeinheit jeweils entladen bzw. entspannt sind.In the representation according to Fig. 4 the carriage 20 is fixed in its locking position, while both the unlocking energy store 16 or the unlocking spring unit and the locking energy store 14 or the locking spring unit are each discharged or relaxed.

In der Darstellung gemäß Fig. 5 ist der Schlitten 20 in seiner Verriegelungsposition festgestellt, während der Entriegelungs-Energiespeicher 16 bzw. die Entriegelungs-Federeinheit durch die motorische Antriebseinheit 12 gegen den festgestellten Schlitten 20 vorgespannt wird, woraufhin der Verriegelungsantrieb 10 wieder seinen bereits in der Fig. 1 dargestellten Anfangszustand einnimmt.In the representation according to Fig. 5 the carriage 20 is fixed in its locking position, while the unlocking energy store 16 or the unlocking spring unit is biased by the motor drive unit 12 against the fixed carriage 20, whereupon the locking drive 10 is already in the Fig. 1 assumes the initial state shown.

Mit dem erfindungsgemäßen Verriegelungsantrieb 10 ist ein Verriegeln und Entriegeln jeweils innerhalb sehr kurzer Zeit bei auf ein Minimum reduzierter Geräuschentwicklung gewährleistet. So erfolgt bei einem jeweiligen Verriegelungs- bzw. Entriegelungsvorgang für das betreffende Verriegeln bzw. Entriegeln des Fenster- bzw. Türflügels zunächst eine Betätigung des diesem zugeordneten Verriegelungsbeschlags durch die in einem jeweiligen Energiespeicher gespeicherte Energie. Erst anschließend wird durch die motorische Antriebseinheit der später zum Entriegeln bzw. Verriegeln benötigte Energiespeicher durch die motorisch Antriebseinheit 12 wieder vorgeladen.With the locking drive 10 according to the invention, locking and unlocking is guaranteed within a very short time with noise development reduced to a minimum. Thus, during a respective locking or unlocking process for the relevant locking or unlocking of the window or door sash, the locking fitting assigned to it is initially actuated by the energy stored in a respective energy store. Only then is the energy store later required for unlocking or locking precharged by the motorized drive unit 12 by the motorized drive unit.
