Description

Die Erfindung betrifft einen Treibstangenbeschlag mit einer motorischen Antriebseinheit mit einem Antriebsmotor sowie mit einem Spindelgetriebe zwischen dem Antriebsmotor und einer Treibstangenanordnung des Treibstangenbeschlages, über welches der Antriebsmotor mit der Treibstangenanordnung antriebsverbindbar ist und welches eine mittels des Antriebsmotors um ihre Achse in wenigstens einer Drehrichtung drehbare Getriebespindel sowie eine auf der Getriebespindel aufsitzende und mittels der drehenden Getriebespindel längs dieser bewegbare Spindelmutter umfasst, wobei zwischen der Spindelmutter und der Treibstangenanordnung eine Kupplung mit wenigstens einem mit der Spindelmutter antriebsverbundenen spindelmutterseitigen Kupplungsteil sowie mit wenigstens einem mit der Treibstangenanordnung bewegungsverbundenen treibstangenseitigen Kupplungsteil vorgesehen ist und die Kupplungsteile einerseits wenigstens einen Kupplungsvorsprung und andererseits wenigstens eine Kupplungsaufnahme aufweisen und ineinander einrückbar sind und wobei die Spindelmutter bei ineinander eingerückten Kupplungsteilen gemeinschaftlich mit diesen von der drehenden Getriebespindel mit einer Vorschubbewegung längs der Getriebespindel bewegbar ist.The invention relates to a drive rod fitting with a motor drive unit with a drive motor and with a Spindle gear between the drive motor and a drive rod assembly of the espagnolette, over which the drive motor drivably connectable to the drive rod assembly is and which one by means of the drive motor about its axis in at least one direction rotatable gear spindle as well one sitting on the gear spindle and by means of the rotating Includes gear spindle along this movable spindle nut, wherein between the spindle nut and the drive rod assembly a clutch with at least one with the spindle nut drive-connected spindle nut side coupling part and with at least one movement associated with the drive rod assembly provided drive rod side coupling part is and the coupling parts on the one hand at least one coupling projection and on the other hand, at least one coupling receptacle and are engageable with each other and wherein the Spindle nut with engaged clutch parts jointly with these of the rotating gear spindle with a feed movement along the gear spindle is movable.

Eine derartige Vorrichtung ist bekannt aus DE 199 38 253 A1. Im Falle des Standes der Technik ist die mittels eines Antriebsmotors bewegbare Spindelmutter eines Spindelgetriebes mit einer Blattfeder versehen, die in Längsrichtung einer mit der Spindelmutter zusammenwirkenden Getriebespindel von der Spindelmutter vorsteht und an ihrem freien Ende einen sich in Querrichtung der Getriebespindel erstreckenden Mitnehmer aufweist. Die Blattfeder ist in Querrichtung der Getriebespindel zwischen der Spindelmutter und einer über das Spindelgetriebe anzutreibenden Treibstange angeordnet. Zur Herstellung einer Antriebsverbindung zwischen der Spindelmutter und der Treibstange wird die Blattfeder mit einer quer zu der Getriebespindel gerichteten Bewegung an dem Mitnehmer mit der Treibstange verrastet. Der Mitnehmer an der Blattfeder taucht dabei in eine Ausnehmung der Treibstange ein. Die Höhe des Mitnehmers entspricht in etwa der Dicke der Treibstange. Beide sind gleichermaßen gering. Entsprechend unsicher und störungsanfällig ist der sich zwischen der Blattfeder bzw. der Spindelmutter einerseits und der Treibstange andererseits in Längs- und damit in Bewegungsrichtung der Treibstange ergebende Formschluss.Such a device is known from DE 199 38 253 A1. in the Case of the prior art is that by means of a drive motor movable spindle nut of a spindle gear with a Leaf spring provided, the longitudinal one with the spindle nut interacting gear spindle of the spindle nut protrudes and at its free end a in the transverse direction having the transmission spindle extending driver. The Leaf spring is in the transverse direction of the gear spindle between the Spindle nut and an over the spindle gear to be driven Driving rod arranged. For producing a drive connection between the spindle nut and the drive rod is the Leaf spring with a transversely directed to the gear spindle Motion locked to the driver with the drive rod. Of the Driver on the leaf spring dives into a recess of the Drive rod. The height of the driver corresponds approximately to the Thickness of the drive rod. Both are equally low. Corresponding unsafe and prone to failure is between the leaf spring or the spindle nut on the one hand and the drive rod on the other hand in the longitudinal direction and thus in the direction of movement the drive rod resulting positive locking.

Die Sicherheit der Antriebsverbindung zwischen der Spindelmutter und der anzutreibenden Treibstange bei möglichst geringer Bauhöhe der Gesamtanordnung zu verbessern, hat sich die vorliegende Erfindung zum Ziel gesetzt.The safety of the drive connection between the spindle nut and the drive rod to be driven as low as possible To improve overall height of the overall arrangement, the present has become Invention set to the goal.

Erfindungsgemäß gelöst wird diese Aufgabe durch den Treibstangenbeschlag mit motorischer Antriebseinheit nach Patentanspruch 1. Demnach ist im Falle der Erfindung vorgesehen, dass eine Formschlussverbindung zwischen spindelmutterseitigen und treibstangenseitigen Kupplungsteilen durch eine seitliche, in Umfangsrichtung der Getriebespindel ausgeführte Bewegung hergestellt wird. Auf diese Art und Weise kann zwischen den beiderseitigen Kupplungsteilen ein verhältnismäßig großflächiger Formschluss erzielt werden, ohne dass zu diesem Zweck eine große Bauhöhe in Querrichtung der Getriebespindel erforderlich wäre. Die miteinander in Eingriff zu bringenden Kupplungsteile müssen zur Herstellung des Formschlusses einander nicht in Querrichtung der Getriebespindel ausweichen. Auch dadurch wird der zur Montage des erfindungsgemäßen Treibstangenbeschlags benötigte Einbauraum in Querrichtung der Getriebespindel niedrig gehalten. This object is achieved according to the invention by the drive rod fitting with motor Drive unit according to claim 1. Accordingly, in the case of Invention provided that a positive connection between spindle nut side and drive rod side coupling parts by a lateral, in the circumferential direction of the gear spindle executed movement is made. In this way can be a relative between the mutual coupling parts large-area positive connection can be achieved without too this purpose, a large height in the transverse direction of the gear spindle would be required. To be engaged with each other Coupling parts must be used to produce the positive connection do not dodge each other in the transverse direction of the gear spindle. This also makes the assembly of the invention Espagnolette fitting installation space in the transverse direction of the gear spindle kept low.

Besondere Ausführungsarten der Erfindung nach Patentanspruch 1 ergeben sich aus den abhängigen Patentansprüchen 2 bis 14.Particular embodiments of the invention according to claim 1 result from the dependent claims 2 to 14.

Im Falle der Erfindungsbauart gemäß Patentanspruch 2 besteht zweckmäßigerweise die Möglichkeit, von einem motorischen in einen manuellen Betrieb der Treibstangenanordnung überzugehen. Etwa bei Verwendung elektrischer Antriebsmotoren kann ein derartiger Übergang in den manuellen Betrieb bei Stromausfall erforderlich werden. Die anspruchsgemäße Konstruktion erlaubt es, die formschlüssig miteinander verbundenen Kupplungsteile durch manuelle Verschiebung der Treibstangenanordnung und damit verbundene Relativbewegung der Kupplungsteile entlang der vorgesehenen Entkupplungssteuerfläche(n) auseinander auszurücken.In the case of Erfindungsbauart according to claim 2 is expediently the possibility of a motor in one to go over manual operation of the drive rod assembly. When using electric drive motors, such a Transition to manual operation required in case of power failure become. The claimed construction allows the form-fitting interconnected coupling parts manual displacement of the drive rod assembly and associated Relative movement of the coupling parts along the provided Disconnect control surface (s) apart.

Ausweislich Patentanspruch 3 ist in Weiterbildung der Erfindung wenigstens eine Entkupplungssteuerfläche unmittelbar an den Kupplungsteilen der motorischen Antriebseinheit vorgesehen. Mit einfachen konstruktiven Mitteln und mit einer Mindestzahl von Bauteilen wird auf diese Art und Weise der gewünschte Übergang von dem motorischen in den manuellen Betrieb der Treibstangenanordnung ermöglicht.Proof of claim 3 is in development of the invention at least one decoupling control surface directly to the Coupling parts of the motor drive unit provided. With simple constructive means and with a minimum number of Components will in this way the desired transition from the motor to the manual operation of the drive rod assembly allows.

Patentanspruch 4 beschreibt eine Variante der Erfindung, im Falle derer die einander zugeordneten Kupplungsteile in einem Ausgangs-Betriebszustand in Vorschubrichtung gegeneinander versetzt und somit auseinander ausgerückt sind. Bei diesem Betriebszustand der Kupplungsteile ist die Treibstangenanordnung manuell frei beweglich. Soll der motorische Antrieb die Verschiebung der Treibstangenanordnung übernehmen, so sind Spindelmutter und Treibstangenanordnung miteinander in Antriebsverbindung zu bringen. Zu diesem Zweck wird zunächst das spindelmutterseitige Kupplungsteil entlang der drehenden Getriebespindel in Vorschubrichtung bewegt. Infolge der erfindungsgemäßen Mitnahme der Spindelmutter durch die Getriebespindel werden Spindelmutter und spindelmutterseitiges Kupplungsteil dabei in Mitnahmedrehrichtung beaufschlagt. Bei oder vor Erreichen des treibstangenseitigen Kupplungsteils bewirkt die anspruchsgemäße Kupplungssteuerfläche eine Auslenkung der einander zugeordneten Kupplungsteile relativ zueinander und quer zur Vorschubrichtung des spindelmutterseitigen Kupplungsteils. Auf diese Art und Weise wird eine antriebsblockierende Kollision der beiderseitigen Kupplungsteile verhindert und das spindelmutterseitige Kupplungsteil in Vorschubrichtung in eine Position bewegt, in welcher es in eine Formschlussverbindung mit dem treibstangenseitigen Kupplungsteil treten kann. Aufgrund der beschriebenen Funktionsweise lassen sich die Positionen, welche das spindelmutterseitige und das treibstangenseitige Kupplungsteil im Ausgangs-Betriebszustand relativ zueinander in Vorschubrichtung einnehmen, in verhältnismäßig weiten Grenzen wählen, ohne dass dadurch eine funktionssichere Herstellung des Formschlusses zwischen den beiden Kupplungsteilen gefährdet würde. Claim 4 describes a variant of the invention, in Fall of which the associated coupling parts in one Output operating state in the feed direction offset from each other and thus disassembled. In this operating state the coupling parts is the drive rod assembly manually freely movable. If the motor drive, the shift assume the drive rod assembly, so are spindle nut and the drive rod assembly in drive connection with each other bring to. For this purpose, first the spindle nut side Coupling part along the rotating gear spindle moved in the feed direction. As a result of the invention Take the spindle nut through the gear spindle Spindle nut and spindle nut side coupling part in Mitnahmedrehrichtung applied. At or before reaching the Drive rod-side coupling part causes the claimed Clutch control surface, a deflection of the associated Coupling parts relative to each other and transverse to the feed direction of the spindle-side coupling part. In this way and Way becomes a drive-blocking collision of the mutual Coupling parts prevented and the spindle nut side Coupling part moves in the feed direction to a position in which it in a positive connection with the drive rod side Coupling part can occur. Due to the described Functioning can be the positions of the spindle nut side and the drive rod-side coupling part in the output operating state relative to each other in the feed direction to take, to choose in relatively wide limits, without that thereby a functionally reliable production of the positive connection would be compromised between the two coupling parts.

Gemäß Patentanspruch 5 ist in bevorzugter Ausgestaltung der Erfindung zumindest eine Kupplungssteuerfläche an den einander zugeordneten Kupplungsteilen vorgesehen. Die Verwendung zusätzlicher, Einbauraum benötigender Bauteile zur gegenseitigen Bewegungsführung der Kupplungsteile erübrigt sich dadurch.According to claim 5 is in a preferred embodiment of the invention at least one clutch control surface against each other assigned coupling parts provided. The use of additional, Installation space required components for mutual motion control the coupling parts is unnecessary.

Ausweislich Patentanspruch 6 wird das spindelmutterseitige Kupplungsteil bei der von dem Ausgangs-Betriebszustand ausgehenden Bewegung mittels einer Blockiereinrichtung gegen Mitnahme durch die Getriebespindel in Mitnahmedrehrichtung blockiert. Dadurch wird sichergestellt, dass das spindelmutterseitige Kupplungsteil mit einer definierten Drehstellung auf das treibstangenseitige Kupplungsteil aufläuft. Auch diese Maßnahme dient insbesondere einer funktionssicheren Herstellung der Formschlussverbindung zwischen spindelmutterseitigem und treibstangenseitigem Kupplungsteil.As shown in claim 6, the spindle nut side Coupling part at the outgoing from the initial operating condition Movement by means of a blocking device against entrainment blocked by the gear spindle in driving direction of rotation. This will ensure that the spindle nut side Coupling part with a defined rotational position on the drive rod side Clutch part runs up. Also this measure serves in particular a functionally reliable production of Positive connection between the spindle nut side and the drive rod side Coupling part.

Der Einfachheit halber dient in Weiterbildung der Erfindung als Blockiereinrichtung für das spindelmutterseitige Kupplungsteil ein in Mitnahmedrehrichtung wirksamer Anschlag für das spindelmutterseitige Kupplungsteil und/oder für die Spindelmutter (Patentanspruch 7). Wird als Anschlag für das spindelmutterseitige Kupplungsteil und/oder für die Spindelmutter ein Antriebsgehäuse der motorischen Antriebseinheit genutzt, wie dies gemäß Patentanspruch 8 vorgesehen ist, so ergibt sich ein konstruktiv besonders einfacher Aufbau der Gesamtanordnung. For simplicity, in a further development of the invention serves as Blocking device for the spindle nut side coupling part a dead-center stopper for the spindle nut side Coupling part and / or for the spindle nut (claim 7). Used as a stop for the spindle nut side Coupling part and / or for the spindle nut a drive housing used the motor drive unit, as claimed in claim 8 is provided, this results in a constructive particularly simple construction of the overall arrangement.

Patentanspruch 9 betrifft einen erfindungsgemäßen Treibstangenbeschlag mit motorischer Antriebseinheit, im Falle derer die Getriebespindel in beiden Drehrichtungen drehbar und folglich die Spindelmutter sowie die damit kuppelbare Treibstangenanordnung in einander entgegengesetzten Vorschubrichtungen bewegbar ist. Mittels derartiger Antriebseinheiten lassen sich etwa über die Treibstangenanordnung zu betätigende Verriegelungen und/oder Ausstellvorrichtungen an mit der Treibstangenanordnung versehenen Fenstern, Türen oder dergleichen sowohl öffnen als auch schließen.Claim 9 relates to a drive rod fitting according to the invention with motor drive unit, in the case of those the gear spindle in both directions rotatable and consequently the spindle nut and the detachable with it Espagnolette in opposite directions Feed directions is movable. By means of such drive units can be about the drive rod assembly to actuating latches and / or Ausstellvorrichtungen on provided with the rod assembly windows, doors or like both open and close.

Gemäß Patentanspruch 10 weisen Antriebseinheiten zur Bewegung von Treibstangenanordnungen in einander entgegengesetzten Richtungen für jede Richtung die vorstehend erläuterten Merkmale wenigstens eines der Patentansprüche 2 bis 8 auf.According to claim 10 have drive units for moving espagnolette assemblies in opposite directions Directions for each direction explained above Features of at least one of the claims 2 to 8 on.

Im Interesse einer möglichst einfachen und platzsparenden Konstruktion der Gesamtanordnung ist gemäß Patentanspruch 11 vorgesehen, dass die spindelmutterseitigen und/oder die treibstangenseitigen Kupplungsteile für beide Vorschubrichtungen jeweils einstückig miteinander verbunden sind.In the interests of a simple and space-saving construction the overall arrangement is provided according to claim 11, that the spindle nut side and / or the drive rod side Coupling parts for both directions of feed respectively are integrally connected to each other.

Die Erfindungsvariante gemäß Patentanspruch 12 zeichnet sich dadurch aus, dass die miteinander formschlüssig verbundenen Kupplungsteile automatisch auseinander ausgerückt werden, sobald die Spindelmutter in wenigstens einer vorschubrichtung eine Endstellung erreicht. Durch Reversierung der Antriebsrichtung der Getriebespindel werden das spindelmutterseitige und das treibstangenseitige Kupplungsteil relativ zueinander in eine Position überführt, bei deren Einnahme sie die Treibstangenanordnung etwa zur manuellen Betätigung freigeben. Darüber hinaus kann der sich nach Trennung der beiderseitigen Kupplungsteile ergebende Betriebszustand den Ausgangs-Betriebszustand darstellen, mit dem beginnend das spindelmutterseitige Kupplungsteil in einer der Richtung der vorausgegangenen Vorschubbewegung entgegengesetzten Vorschubrichtung bewegt wird.The variant of the invention according to claim 12 is distinguished characterized in that the positively connected with each other Clutch parts are automatically disengaged as soon as possible the spindle nut in at least one feed direction a End position reached. By reversing the drive direction the gear spindle are the spindle nut side and the drive rod side coupling part relative to each other in a Position transferred when they take the drive rod assembly for example, release for manual operation. Furthermore may be after separation of the mutual coupling parts resulting operating state the output operating state represent, starting with the spindle-side coupling part in one of the directions of the previous feed motion opposite feed direction is moved.

Als Antriebsmotor einen Motor zu verwenden, dessen Drehzahl - wie im Falle der Erfindungsbauart nach Patentanspruch 14 vorgesehen - im Wesentlichen lastunabhängig ist, empfiehlt sich im Interesse einer größtmöglichen Benutzerfreundlichkeit der Antriebseinheit. So wird die im Wesentlichen konstante Drehzahl des Antriebsmotors von Personen, die sich in der Nähe der motorischen Antriebseinheit aufhalten, als angenehm gleichförmig empfunden. Diese Antriebskonfiguration kann aber auch dahingehend abgewandelt sein, dass ein Antriebsmotor mit einer mit zunehmender Last geringfügig abfallenden Drehzahl verwendet wird. In diesem Fall bleibt das beschriebene akustische Erscheinungsbild der Antriebseinheit nahezu unverändert erhalten; gleichzeitig eignen sich derartige Antriebseinheiten besonders für Anwendungsfälle, in denen mehrere Antriebe benötigt werden. Mechanisch mehr belastete Antriebe laufen dabei etwas langsamer, sodass weniger belastete Antriebe infolge ihrer höheren Drehzahl "aufholen" und die stärker belasteten Antriebe dann wieder unterstützen können.As a drive motor to use a motor whose speed - as provided in the case of Erfindungsbauart according to claim 14 - is essentially load independent, is recommended in Interested in the utmost ease of use of Drive unit. So that's essentially constant speed of the drive motor of persons who are in Keep the proximity of the motor drive unit as pleasant felt uniform. This drive configuration but can also be modified to that effect that a drive motor with one with increasing load slightly decreasing speed is used. In this case remains the described acoustic appearance of the drive unit preserved almost unchanged; At the same time, such are suitable Drive units especially for applications in which several drives are needed. Mechanically more loaded Drives run a little slower, so less loaded Drives due to their higher speed "catch up" and the more heavily loaded drives can then support again.

Bei der Montage bilden das Antriebsgehäuse 11, der Antriebsmotor 2 mit dem Spindelgetriebe 3 und das Treibstangenantriebselement 24 eine Baueinheit. Diese Baueinheit wird auf einen Flügelfalz 32 senkrecht zu diesem aufgesetzt. Das Treibstangenantriebselement 24, die Kupplung 26 und auch noch ein Randbereich der Spindelmutter 8 tauchen bei Einbaulage der motorischen Antriebseinheit 1 in eine Beschlagteilnut 33 an dem Flügelfalz 32 ein.

Im Einzelnen ist die Einbausituation in Fig. 2 dargestellt. During assembly, the drive housing 11, the drive motor 2 with the spindle gear 3 and the drive rod drive element 24 a unit. This unit will be on a Flügelfalz 32 mounted perpendicular to this. The drive rod drive element 24, the clutch 26 and also a peripheral area the spindle nut 8 dive in installation position of the motor Drive unit 1 in a fitting part 33 on the Flügelfalz 32 on. In the fitting part 33, the drive rod drive element 24 at its longitudinal ends with the drive rods 18, 20 of the drive rod assembly 21 connected.

In detail, the installation situation in FIG. 2 shown.

Die Funktionsweise der motorischen Antriebseinheit 1 ergibt sich aus den Fign. 3 bis 8. Diese Figuren sind allesamt Doppeldarstellungen, die zum einen den Bereich von Spindelgetriebe 3 und Kupplung 26 in perspektivischer Ansicht und zum ändern einen parallel zu dem Treibstangen-Antriebselement 24 verlaufenden Schnitt durch die spindelmutterseitigen Kupplungsteile 27, 28 und die treibstangenseitigen Kupplungsteile 29, 30 zeigen.The operation of the motor drive unit 1 results from the Fign. 3 to 8. These figures are all duplicate representations, on the one hand, the range of spindle gear. 3 and coupling 26 in perspective view and to change one extending parallel to the drive rod drive element 24 Section through the spindle nut side coupling parts 27, 28 and the drive rod-side coupling parts 29, 30 show.

In einem Ausgangs-Betriebszustand ist die motorische Antriebseinheit 1 in Fig. 3 dargestellt. Die Spindelmutter 8 nimmt auf der Getriebespindel 4 eine Position nahe der motorseitigen Halterung 6 ein. Die spindelmutterseitigen Kupplungsteile 27, 28 liegen über der Längsmitte des Treibstangenantriebselementes 24 und damit zwischen den treibstangenseitigen Kupplungsteilen 29, 30 (Fig. 9b).In an initial operating state is the motor drive unit 1 shown in Fig. 3. The spindle nut 8 receives the gear spindle 4 a position near the motor-side bracket 6 on. The spindle nut side coupling parts 27, 28 lie above the longitudinal center of the drive rod drive element 24 and thus between the drive rod side coupling parts 29, 30 (Figure 9b).

Ausweislich der Fign. 3 bis 8 sind die spindelmutterseitigen Kupplungsteile 27, 28 zu einem einstückigen, S-förmigen Bauteil zusammengefasst. Die Längsenden der spindelmutterseitigen Kupplungsteile 27, 28 sind unter Ausbildung von Kupplungssteuerflächen 34, 35 abgeschrägt. An ihren Längsseiten weisen die spindelmutterseitigen Kupplungsteile 27, 28 Kupplungsaufnahmen 36, 37 auf. Letztere werden u.a. von Stützflächen 38, 40 und Entkupplungssteuerflächen 39, 41 begrenzt. Evidenced the Fign. 3 to 8 are the spindle nut side Coupling parts 27, 28 to a one-piece, S-shaped component summarized. The longitudinal ends of the spindle nut side coupling parts 27, 28 are under formation of clutch control surfaces 34, 35 bevelled. On their long sides have the spindle nut side Coupling parts 27, 28 coupling receptacles 36, 37 on. The latter are u.a. of support surfaces 38, 40 and decoupling control surfaces 39, 41 limited.

Die treibstangenseitigen Kupplungsteile 29, 30 weisen jeweils einen Kupplungsvorsprung 48, 49 auf und sind in Längsrichtung des Treibstangenantriebselementes 24, d.h. in Richtung der Achse 10 der Vorschubbewegung der Spindelmutter 8 einerseits mit Stützflächen 42, 44 und andererseits mit Entkupplungssteuerflächen 43, 45 versehen.The drive rod-side coupling parts 29, 30 each have a coupling projection 48, 49 and are in the longitudinal direction of the drive rod drive element 24, i. in the direction of the axis 10 of the feed movement of the spindle nut 8 on the one hand with Support surfaces 42, 44 and on the other hand with Entkupplungssteuerflächen 43, 45 provided.

An der Außenseite der Spindelmutter 8 verlaufen Anschlagleisten 46, 47 in Richtung der Achse 10 der Vorschubbewegung der Spindelmutter 8. In größerem Maßstab sind die Anschlagleisten 46, 47 der Spindelmutter 8 in den Fign. 9a, 9b und 9c dargestellt.On the outside of the spindle nut 8 run stop strips 46, 47 in the direction of the axis 10 of the feed movement of the spindle nut 8. On a larger scale, the stop strips 46, 47 of the spindle nut 8 in Figs. 9a, 9b and 9c shown.

Wird nun ausgehend von den Verhältnissen gemäß Fig. 3 die Getriebespindel 4 mittels des Antriebsmotors 2 in Richtung des in Fig. 3 dargestellten Pfeils in Drehbewegung versetzt, so nimmt die Getriebespindel 4 die auf ihr aufsitzende Spindelmutter 8 zunächst in dieser Drehrichtung (Mitnahmedrehrichtung) mit. Die daraus resultierende Drehbewegung der Spindelmutter 8 um die Längsachse der Getriebespindel 4 endet, sobald die Anschlagleisten 46, 47 auf der Außenwand der Getriebespindel 8 an der Innenwand des Antriebsgehäuses 11 anschlagen. Die Anschlagleisten 46, 47 und das Antriebsgehäuse 11 bilden also miteinander zusammenwirkende Anschläge (Fig. 9a). Die spindelmutterseitigen Kupplungsteile 27, 28 sind nun aus der Längsmittelebene des Treibstangenantriebselementes 24 seitlich ausgeschwenkt. Die sich insgesamt ergebenden Verhältnisse sind in Fig. 4 dargestellt.Now, starting from the ratios shown in FIG. 3, the gear spindle 4 by means of the drive motor 2 in the direction of in Fig. 3 arrow shown in rotation, so takes the gear spindle 4, the seated on her spindle nut. 8 first in this direction of rotation (driving direction of rotation) with. The resulting rotational movement of the spindle nut 8 to the Longitudinal axis of the gear spindle 4 ends as soon as the stop strips 46, 47 on the outer wall of the gear spindle 8 on the inner wall of the drive housing 11 strike. The stop strips 46, 47 and the drive housing 11 thus form cooperating with each other Stops (Fig. 9a). The spindle nut side Clutch parts 27, 28 are now from the longitudinal center plane of the Espagnolette drive element 24 swung laterally. The Overall resulting ratios are shown in Fig. 4.

Die fortgesetzte Drehbewegung der Getriebespindel 4 in der anfänglichen Drehrichtung bewirkt eine Vorschubbewegung der in der Mitnahmedrehrichtung blockierten Spindelmutter 8 auf der Getriebespindel 4 in den Abbildungen nach rechts. Mit den Anschlagleisten 46, 47 gleitet die Spindelmutter 8 dabei an der Innenwand des Antriebsgehäuses 11 entlang.The continued rotational movement of the gear spindle 4 in the initial Direction of rotation causes a feed movement in the driving direction of rotation locked spindle nut 8 on the Gear spindle 4 in the pictures to the right. With the stop strips 46, 47, the spindle nut 8 slides on the Inner wall of the drive housing 11 along.

Infolge der Vorschubbewegung der Spindelmutter 8 läuft das spindelmutterseitige Kupplungsteil 27 mit seiner Kupplungssteuerfläche 34 auf das treibstangenseitige Kupplungsteil 29 auf (Fig. 5). Bei fortgesetzter Vorschubbewegung der Spindelmutter 8 bewirken die Kupplungssteuerfläche 34 an dem spindelmutterseitigen Kupplungsteil 27 und das treibstangenseitige Kupplungsteil 29 im Zusammenwirken ein seitliches Ausweichen des spindelmutterseitigen Kupplungsteils 27 gegenüber dem treibstangenseitigen Kupplungsteil 29. Die Spindelmutter 8 wird entgegen der von der Getriebespindel 4 in Mitnahmedrehrichtung ausgeübten Beaufschlagung in Richtung auf ihre Ausgangs-Drehstellung zurückgedreht, bis das spindelmutterseitige Kupplungsteil 27 gegenüber dem treibstangenseitigen Kupplungsteil 29 die in Fig. 6 gezeigte Position einnimmt. Mit dieser Drehstellung werden die Spindelmutter 8 und das spindelmutterseitige Kupplungsteil 27 weiter in Vorschubrichtung der Spindelmutter 8 bewegt. Nach wie vor beaufschlagt die drehende Getriebespindel 4 die Spindelmutter 8 in Mitnahmedrehrichtung.As a result of the feed movement of the spindle nut 8 that runs spindle-side coupling part 27 with its clutch control surface 34 on the drive rod-side coupling part 29 (Figure 5). With continued feed movement of the spindle nut 8 cause the clutch control surface 34 on the spindle nut side Coupling part 27 and the drive rod side coupling part 29 in cooperation a lateral evasion of the spindle-side coupling part 27 with respect to the drive rod side Coupling member 29. The spindle nut 8 is opposite that of the gear spindle 4 in Mitnahmedrehrichtung exerted application towards their initial rotational position Turned back until the spindle-side coupling part 27 with respect to the drive rod-side coupling part 29 the assumes the position shown in Fig. 6. With this rotational position be the spindle nut 8 and the spindle nut side coupling part 27 further moved in the feed direction of the spindle nut 8. As before, the rotating gear spindle 4 acts the spindle nut 8 in Mitnahmedrehrichtung.

Infolge dieser Beaufschlagung schwenkt das spindelmutterseitige Kupplungsteil 27, sobald es mit seiner Kupplungsaufnahme 36 auf Höhe des treibstangenseitigen Kupplungsteils 29 bzw. dessen Kupplungsvorsprungs 48 liegt, in die aus Fig. 7 ersichtliche Stellung ein. Das treibstangenseitige Kupplungsteil 29 liegt nun mit seinem Kupplungsvorsprung 48 im Innern der Kupplungsaufnahme 36 an dem spindelmutterseitigen Kupplungsteil 27. Infolge des sich an der Stützfläche 38 des spindelmutterseitigen Kupplungsteils 27 und an der Stützfläche 42 des treibstangenseitigen Kupplungsteils 29 ergebenden Formschlusses nimmt das spindelmutterseitige Kupplungsteil 27 das treibstangenseitige Kupplungsteil 29 in Vorschubrichtung der Spindelmutter 8 mit. Daraus resultiert eine entsprechende Verschiebung des Treibstangenantriebselementes 24 und somit eine entsprechende Verschiebung der gesamten Treibstangenanordnung 21.As a result of this admission pivots the spindle nut side Clutch part 27, as soon as it with its coupling receptacle 36 on Height of the drive rod-side coupling part 29 or its Coupling projection 48 is, in the apparent from Fig. 7 Position. The drive rod-side coupling part 29 is located now with its coupling projection 48 inside the coupling receptacle 36 on the spindle nut side coupling part 27. As a result of the on the support surface 38 of the spindle nut side Coupling part 27 and on the support surface 42 of the drive rod side Coupling 29 resulting positive fit takes that spindle-side coupling part 27, the drive rod side Coupling member 29 in the feed direction of the spindle nut 8 with. This results in a corresponding displacement of the drive rod drive element 24 and thus a corresponding shift the entire drive rod assembly 21st

Mit der Verschiebung der Treibstangenanordnung 21 läuft der Riegelzapfen 23 an dem Fensterflügel 22 in ein nicht gezeigtes herkömmliches Schließblech an dem zugehörigen festen Rahmen ein. Sobald der Riegelzapfen 23 seine Verriegelungsstellung erreicht, wird eine weitere Bewegung der Treibstangenanordnung 21 blockiert. Die Blockierung der Treibstangenanordnung 21 überträgt sich über das Treibstangenantriebselement 24 und die Kupplung 26 auf die Spindelmutter 8 und über diese auf die Getriebespindel 4. Die Blockierung der Getriebespindel 4 wiederum führt zu einer Überlastabschaltung des elektrischen Antriebsmotors 2. Die Spindelmutter 8 nimmt nun in Richtung der Achse 10 ihrer Vorschubbewegung die in Fig. 8 gezeigte Position ein. Das spindelmutterseitige Kupplungsteil 27 und das treibstangenseitige Kupplungsteil 29 sind aber abweichend von Fig. 8 nach wie vor ineinander eingerückt.With the displacement of the drive rod assembly 21 runs the Locking pin 23 on the window sash 22 in a not shown conventional strike plate on the associated fixed frame one. As soon as the locking pin 23 reaches its locking position, becomes a further movement of the drive rod assembly 21st blocked. The blocking of the drive rod assembly 21 transmits over the espagnolette drive element 24 and the Clutch 26 on the spindle nut 8 and via this on the gear spindle 4. The blocking of the gear spindle 4 turn leads to an overload shutdown of the electric drive motor 2. The spindle nut 8 now takes in the direction of the axis 10th their feed movement the position shown in Fig. 8 a. The spindle nut side coupling part 27 and the drive rod side But coupling part 29 are deviating from Fig. 8 after in front of each other.

Eine elektronische Antriebssteuerung bewirkt, dass nach der Überlastabschaltung des Antriebsmotors 2 dieser kurzzeitig mit einer gegenüber der ursprünglichen Drehrichtung umgekehrten Drehrichtung betrieben wird. Entsprechend dreht sich die Getriebespindel 4 über einen verhältnismäßig kleinen Drehwinkel entgegen der Richtung der vorausgegangenen Drehbewegung. Dabei nimmt die Getriebespindel 4 die auf ihr aufsitzende Spindelmutter 8 mit. Das spindelmutterseitige Kupplungsteil 27 und das treibstangenseitige Kupplungsteil 29 werden infolge der Reversierung des Antriebes auseinander ausgerückt und befinden sich dann relativ zueinander in der Stellung gemäß Fig. 8. Die spindelmutterseitigen Kupplungsteile 27, 28 liegen nun zwischen den treibstangenseitigen Kupplungsteilen 29, 30. Infolgedessen ist die Treibstangenanordnung 21 in Längsrichtung der Beschlagteilnut 33 des Fensterflügels 22 frei beweglich. Eine derartige Bewegung kann beispielsweise manuell über einen üblichen Handbetätigungsgriff erfolgen. So kann der Fensterflügel 22 etwa manuell entriegelt werden.An electronic drive control causes after the Overload shutdown of the drive motor 2 this briefly with one opposite to the original direction of rotation reversed Direction of rotation is operated. Accordingly, the gear spindle rotates 4 over a relatively small angle of rotation contrary to the direction of the previous rotation. there the gear spindle 4 takes the seated on her spindle nut 8 with. The spindle nut side coupling part 27 and the Drive rod-side coupling part 29 are due to the reversing of the drive disengaged and are located then relative to each other in the position shown in FIG. 8. The spindle nut side Clutch parts 27, 28 are now between the As a result, is the drive rod assembly 21 in the longitudinal direction of the fitting part 33 of the sash 22 freely movable. Such a movement For example, it can be done manually using a standard hand-operated grip respectively. So the sash 22 can be about manually be unlocked.

Erfolgt etwa aufgrund einer irregulären Blockierung der Treibstangenanordnung 21 eine Abschaltung des Antriebsmotors 2, ehe die Treibstangenanordnung 21 bzw. die Spindelmutter 8 eine Endstellung erreicht und somit ehe selbsttätig eine Reversierung des Antriebs erfolgt, so lassen sich das spindelmutterseitige Kupplungsteil 27 und das treibstangenseitige Kupplungsteil 29 manuell auseinander ausrücken. Die Verhältnisse bei vorzeitiger Abschaltung des Antriebsmotors 2 entsprechen grundsätzlich den Verhältnissen gemäß Fig. 7. Hiervon ausgehend ist die Treibstangenanordnung 21 manuell in Richtung der vor der Motorabschaltung ausgeführten Vorschubbewegung zu verlagern. Dabei läuft die Entkupplungssteuerfläche 43 an dem treibstangenseitigen Kupplungsteil 29 zunächst auf die Entkupplungssteuerfläche 39 des spindelmutterseitigen Kupplungsteils 27 auf. Bei fortgesetzter manueller Verlagerung der Treibstangenanordnung 21 bewirken die Entkupplungssteuerflächen 39, 43 als einander zugeordnete Gegenflächen ein Zurückdrehen der Spindelmutter 8 entgegen der vorherigen Mitnahmedrehrichtung und damit ein Lösen der Formschlussverbindung zwischen dem spindelmutterseitigen Kupplungsteil 27 und dem treibstangenseitigen Kupplungsteil 29. Die Kupplungsteile 27, 29 befinden sich dann in einer Position, in welcher sie eine freie manuelle Verschiebung der Treibstangenanordnung 21 zulassen. Occurs as a result of an irregular blocking of the drive rod assembly 21 a shutdown of the drive motor 2, before the drive rod assembly 21 and the spindle nut 8 an end position achieved and thus before automatically reversing the drive takes place, so can the spindle nut side Coupling part 27 and the drive rod-side coupling part 29th manually disengage. The circumstances at premature Shutdown of the drive motor 2 basically correspond to the Conditions according to FIG. 7. On this basis, the drive rod assembly 21 manually in the direction of the engine shutdown shifted feed movement to shift. there the decoupling control surface 43 runs on the drive rod side Clutch part 29 first on the decoupling control surface 39 of the spindle nut side coupling part 27 on. With continued cause manual displacement of the drive rod assembly 21 the decoupling control surfaces 39, 43 as associated with each other Counter surfaces turning back the spindle nut 8 against the previous driving direction of rotation and thus a release the positive connection between the spindle nut side Coupling part 27 and the drive rod-side coupling part 29th The coupling parts 27, 29 are then in a position in which they provide a free manual displacement of the drive rod assembly 21 allow.

Im gezeigten Beispielsfall ist - wie insbesondere Fig. 8 entnommen werden kann - der Abstand der treibstangenseitigen Kupplungsteile 29, 30 in Richtung der Achse 10 der Vorschubbewegung der Spindelmutter 8 derart gewählt, dass bei Reversieren des Antriebes nach Erreichen einer regulären Endlage durch die Spindelmutter 8 das spindelmutterseitige Kupplungsteil 28 mit dem vorderen Rand der Kupplungsaufnahme 37 auf Höhe des treibstangenseitigen Kupplungsteils 30 liegt. Der vordere Rand der Kupplungsaufnahme 37 kann folglich seitlich an das treibstangenseitige Kupplungsteil 30 anschlagen. Folglich wird das spindelmutterseitige Kupplungsteil 28 auch dann in eine Position zwischen den treibstangenseitigen Kupplungsteilen 29, 30 überführt, wenn anlässlich der Reversierung des Antriebes die Getriebespindel 4 über einen an sich zu großen Drehwinkel entgegen der ursprünglichen Richtung dreht.In the example shown is - as in particular Fig. 8 taken can be - the distance of the drive rod side coupling parts 29, 30 in the direction of the axis 10 of the feed movement the spindle nut 8 selected such that when reversing the Drive after reaching a regular end position by the Spindle nut 8, the spindle-side coupling part 28 with the front edge of the coupling receptacle 37 at the level of the drive rod side Coupling 30 is located. The front edge of the Coupler receptacle 37 can therefore laterally to the drive rod side Attach coupling part 30. Consequently, the spindle nut side becomes Clutch part 28 then in a position transferred between the drive rod-side coupling parts 29, 30, when the gear spindle is reversed during the reversing of the drive 4 against a too large rotation angle against the original direction turns.

Wird die motorische Antriebseinheit 1 ausgehend von den Verhältnissen nach Fig. 8 mit einer der ursprünglichen Drehrichtung entgegengesetzten Drehrichtung der Getriebespindel 4 betrieben, so ergeben sich die vorstehend beschriebenen Abläufe in entsprechender Form an dem spindelmutterseitigen Kupplungsteil 28 sowie dem treibstangenseitigen Kupplungsteil 30. Beide Kupplungsteile 28, 30 werden unter Beaufschlagung und Auslenkung der Spindelmutter 8 bzw. des spindelmutterseitigen Kupplungsteils 28 in Mitnahmedrehrichtung der Getriebespindel 4 (Fig. 9c) ineinander eingerückt. Bei ineinander eingerücktem Zustand von spindelmutterseitigem Kupplungsteil 28 und treibstangenseitigem Kupplungsteil 30 wird die Treibstangenanordnung 21 und mit dieser der daran angebrachte Riegelzapfen 23 entgegen der anfänglichen Richtung bewegt. Die Verriegelung des Fensterflügels 22 an dem zugehörigen festen Rahmen wird dadurch gelöst.If the motor drive unit 1 based on the conditions according to Fig. 8 with one of the original direction of rotation operated in the opposite direction of rotation of the gear spindle 4, this results in the processes described above in a corresponding form on the spindle nut side coupling part 28 and the drive rod-side coupling part 30. Both Clutch parts 28, 30 are under application and deflection the spindle nut 8 and the spindle nut side coupling part 28 in driving direction of rotation of the gear spindle 4th (Figure 9c) are engaged. With each other indented Condition of spindle-side coupling part 28 and drive rod side Clutch member 30 becomes the drive rod assembly 21 and with this attached thereto locking pin 23 against the initial direction moves. The locking of the window sash 22 on the associated fixed frame is characterized solved.

Erreicht die Treibstangenanordnung 21 ihre zweite Endstellung, erreicht also die Spindelmutter 8 ihre motorseitige Endposition, so schaltet der Antriebsmotor 2 in der bisherigen Antriebsrichtung selbsttätig ab. Die Antriebssteuerung bewirkt eine kurzfristige Reversierung des Antriebes, aufgrund derer das spindelmutterseitige Kupplungsteil 28 und das treibstangenseitige Kupplungsteil 30 auseinander ausgerückt und in den Ausgangs-Betriebszustand gemäß Fig. 3 überführt werden.If the drive rod assembly 21 reaches its second end position, Thus, the spindle nut 8 reaches its motor end position, Thus, the drive motor 2 switches in the previous drive direction automatically off. The drive control causes a short-term reversing of the drive, due to which the spindle-side coupling part 28 and the drive rod side Clutch member 30 disengaged and in the initial operating condition be transferred according to FIG.

Im gezeigten Beispielsfall wird als Antriebsmotor 2 ein Elektromotor verwendet, dessen Drehzahl sich mit zunehmender Last nur geringfügig ändert.In the example shown, the drive motor 2 is an electric motor used, the speed of which increases with increasing load only slightly changes.
