Abstract

The self-locking system, for a swing panel (2), has a swing locking member (15) which is mounted to the frame (1) so that, when released, the panel (2) can move into an open position and, in the closed position, it grips over a step (3) at the panel (2). A toggle lever operating system (8,13,14) swings the locking member (15) between the released/locked positions with movement through a dead point, and especially shortly before reaching the locked position. When in the locked position, the locking member (15) automatically braces the panel (2) against an opening movement force.

Description

Die Erfindung betrifft eine Verriegelungseinrichtung für Flügel von Fenstern, Türen oder dergleichen, insbesondere für motorisch zwischen Schließ- und Offenstellung bewegbare Flügel.The invention relates to a locking device for sashes of windows, doors or the like, especially for motorized between the closed and open positions movable wings.

Die Erfindung ist besonders geeignet als Zusatzverriegelung bei Fenstern im Oberlichtbereich, deren Flügel mit Elektroscheren oder dergleichen motorischen Antrieben bewegbar sind. Insbesondere bei derartigen Flügeln erfolgt der Flügelandruck oft nur an ein oder zwei Punkten des Flügelüberschlages. Dies reicht für ein sicheres und dichtes Andrücken des Flügels in der Schließstellung oft nicht aus, insbesondere dann, wenn, wie bei motorisch angetriebenen Flügeln, ein Zentralverschluß im Flügel fehlt. Damit fehlt auch die Möglichkeit, den Flügel in der Schließstellung mit ausreichendem Flügelandruck zu halten, so daß undichte Fenster die Folge sind. Hinzu kommt, daß ein solcher Flügel ohne große Schwierigkeiten durch äußere Einwirkung aufgedrückt werden kann, so daß bei motorisch betriebenen Flügeln der Einbruchsschutz dürftig ist. Außerdem müssen unterschiedliche Überschlaghöhen der Flügelprofile berücksichtigt werden. Dies kann dazu führen, daß die bekannten Systeme gewisse Funktionsunsicherheiten bei unterschiedlich abstehenden Flügeln kurz vor der Verschlußstellung aufweisen.The invention is particularly suitable as an additional lock for windows in Skylight area, whose wings with electric scissors or the like motorized Drives are movable. In particular with such wings Wing pressure often only at one or two points of the wing flap. This is enough for a secure and tight pressing of the wing in the closed position is often not sufficient, especially when, as with motor-driven wings, a Central lock in the wing is missing. This also means that the wing is missing in the To keep the closed position with sufficient sash pressure, so that leaky windows are the result. In addition, such a wing passes through without great difficulty external influence can be pressed, so that with motor-operated wings burglary protection is poor. In addition, different rollover heights are required of the wing profiles are taken into account. This can lead to the well-known Systems certain functional uncertainties with differently projecting wings have just before the closed position.

Es ist Aufgabe der Erfindung eine Verriegelungseinrichtung für Flügel zu schaffen, die unabhängig von der normalen Betätigung des Flügels als Zusatzeinrichtung eingesetzt werden kann, um den Flügel zuverlässig, d. h. dicht, zu schließen und/oder so zu verriegeln, daß eine bessere Einbruchssicherheit erhalten wird.It is an object of the invention to provide a locking device for wings, which can be used as an additional device independent of the normal actuation of the wing in order to close and / or lock the wing reliably, ie tightly, in such a way that better security against burglary is obtained.

Diese Aufgabe wird durch eine Verriegelungseinrichtung gemäß der Lehre des Anspruchs 1 oder 3 gelöst.This task is performed by a locking device according to the teaching of Claim 1 or 3 solved.

Es können dabei eine oder mehrere zusätzlich zu der üblichen Betätigungseinrichtung am Blendrahmen montierbare zusätzliche Verriegelungseinrichtungen vorgesehen werden, die unabhängig voneinander montiert werden und arbeiten können. Durch eine solche Verriegelungseinrichtung, bei großen Fenstern durch mehrere derartige Verriegelungseinrichtungen, läßt sich ein zuverlässiger Flügelandruck erreichen und zugleich der Flügel gegen äußere, im Öffnungssinne wirkende Kräfte zuverlässig verriegeln, so daß eine hohe Einbruchssicherheit erreicht wird.There can be one or more in addition to the usual actuator additional locking devices can be mounted on the frame that can be assembled and operated independently. By a such locking device, for large windows by several such Locking devices, a reliable wing pressure can be achieved and at the same time, the wing is reliable against external forces acting in the opening direction lock so that a high level of security against burglary is achieved.

Das (hakenförmige) Verriegelungsglied (Anspruch 14) ist über ein kniehebelartiges Betätigungssystem zwischen seinen beiden Endstellungen verschwenkbar, wobei das kniehebelartige Betätigungssystem bei seinen Bewegungen zwischen den Endstellungen des Verriegelungsgliedes seine Streck- bzw. Totpunktlage überschreitet oder durchläuft, und zwar kurz vor Erreichen der Verriegelungsendstellung. Der Drehwinkel über dem Totpunkt bzw. der Strecklage ist etwa 10°, bevorzugt zwischen 10° und 20°, gerechnet aus der Strecklage, bei der die Wellenachse und die beiden Gelenke des Kniehebelstücks in einer Geraden liegen (Anspruch 15).The (hook-shaped) locking member (claim 14) is a toggle-like Actuating system between its two end positions, the toggle-type operating system in its movements between the End positions of the locking member exceeds its extension or dead center position or runs through, shortly before reaching the locking end position. The Angle of rotation above the dead center or the stretched position is approximately 10 °, preferably between 10 ° and 20 °, calculated from the extended position at which the shaft axis and the two Joints of the toggle lever piece lie in a straight line (claim 15).

Das kniehebelartige Betätigungssystem selbst kann motorisch angetrieben sein (Anspruch 6), und zwar unabhängig von dem sonstigen Betätigungssystem des Flügels.The toggle-type actuation system itself can be motor-driven (Claim 6), regardless of the other actuation system of the Wing.

Der motorische Antrieb ist auf der selben Seite angeordnet, wie das verschwenkbare Verriegelungsglied. Die Anordnung kann an einer Platte oder einem Gehäuse erfolgen, wobei die Platte selbst am Blendrahmen befestigbar ist. Die motorische Betätigung durch einen beispielsweise Elektromotor geht von einer Achse aus, die im wesentlichen parallel zu der Verschwenkachse des Verriegelungsgliedes verläuft.The motor drive is arranged on the same side as the swiveling one Locking member. The arrangement can be made on a plate or a housing, the plate itself being attachable to the frame. The motorized operation by an electric motor, for example, starts from an axis that essentially runs parallel to the pivot axis of the locking member.

Die Verriegelungseinrichtung wird als Ganzes am Blendrahmen befestigt und kann in einem entsprechenden Gehäuse angeordnet sein, in das sich das Verriegelungsglied bei Erreichen seiner Freigabestellung zurückzieht, so daß das Verriegelungsglied in dieser Stellung verdeckt ist.The locking device is attached as a whole to the frame and can in be arranged in a corresponding housing in which the locking member withdraws when it reaches its release position, so that the locking member in this position is hidden.

Die Anbringung der Platte oder des Gehäuses am Blendrahmen erfolgt ohne dort vorzusehende Durchbrüche für den Durchgriff von Betätigungsstangen oder Betätigungsmitteln. Ein solches flaches Aufliegen bewirkt, daß die aktiven Teile der Verriegelungsvorrichtung alle auf derselben Seite angeordnet sind, insbesondere der Antriebsmotor mit dem Ende seiner Antriebswelle eng oder nahe bei der Verschwenkachse des Verriegelungsgliedes zu liegen kommt.The plate or housing is attached to the frame without there Breakthroughs to be provided for the penetration of actuating rods or Actuating means. Such a flat contact causes the active parts of the Locking device are all arranged on the same side, in particular the Drive motor with the end of its drive shaft tight or close to the Pivotal axis of the locking member comes to rest.

Wenn der Flügel zum Beispiel durch ein motorisch angetriebenes Verschlußsystem in die Schließstellung bewegt wird, reicht dessen Antriebskraft für ein festes Andrücken des Flügels zumeist nicht aus, das heißt, am Ende der Bewegung steht der Flügel leicht ab gegenüber dem Blendrahmen. In dieser Stellung wird er von dem Verriegelungsglied erfaßt, das durch seine Drehbewegung den noch leicht abstehenden Flügel heranzieht und den Blendrahmen (gegen die Dichtung zwischen Blendrahmen und Flügelrahmen) fest andrückt. In dieser Stellung hat das kniehebelartige Betätigungssystem seine Strecklage bereits durchlaufen und ist in dieser Stellung selbstsperrend verriegelt, so daß dann, wenn auf das kniehebelartige Betätigungssystem keine Antriebkraft mehr wirksam ist, dennoch die Verriegelungsstellung zuverlässig aufrechterhalten bleibt, und zwar in einem solchen Maße, daß ein dichtes Schließen des Flügels ebenso wie die Sperrung durch von außen einwirkende Öffnungskräfte gewährleistet sind. Das Verriegelungsglied läßt sich somit aus seiner Verriegelungsstellung durch äußere Kräfte nur bei Zerstörung des Verriegelungsgliedes außer Wirkung setzen.For example, if the wing is closed by a motorized locking system the closed position is moved, its driving force is sufficient for a firm pressing of the wing mostly not, that is, the wing is at the end of the movement slightly off compared to the frame. In this position he is from the Locking element detects that by its rotational movement which is still easy protruding sash and the frame (against the seal between Frame and casement) presses firmly. In this position it has toggle-type actuation system already run through its extended position and is in locked this position self-locking, so that when on the toggle-like Actuating system is no longer effective, yet the Locked position is reliably maintained, in such a way Dimensions that a tight closing of the wing as well as the blocking by external opening forces are guaranteed. The locking member can thus from its locking position by external forces only when the Deactivate the locking element.

Wenn die Verriegelungseinrichtung motorisch angetrieben wird, zum Beispiel durch einen Elektromotor, so wird zweckmäßig eine Lastabschaltung des Motors vorgesehen, wodurch nach Erreichen der Verriegelungsstellung (Schließstellung) der Motor stromlos wird. Die Lastabschaltung tritt bei Erreichen beider Endstellungen in Wirkung.If the locking device is driven by a motor, for example by an electric motor, a load cut-off of the motor is expediently provided, whereby the motor is de-energized after reaching the locking position (closed position) becomes. The load cut-off takes effect when both end positions are reached.

Die Einrichtung läßt sich auch so weiterbilden, daß die Positionen des (hakenförmigen) Verriegelungsgliedes elektronisch erfaßt werden. Die Selbstsperrung der Einrichtung in der Verriegelungsstellung wird vorteilhaft durch die Maßnahmen des Anspruchs 2 verwirklicht, wobei der Anspruch 5 auch eine bevorzugte Ausführung für die Selbstsperrung als Ergänzung des Anspruchs 2 und des Anspruchs 1 umfaßt. The device can also be developed so that the positions of the (hook-shaped) Locking element can be detected electronically. Self - locking the facility in the locking position is advantageous through the measures of claim 2 realized, the claim 5 also a preferred embodiment for the Self-locking as a supplement to claim 2 and claim 1 comprises.

Die Erfindung wird nachfolgend anhand von schematischer Zeichnungen an mehreren Ausführungsbeispielen näher erläutert.

show in front view and in cross section of the window the two end positions of the hook-shaped locking member of the locking device in the embodiment of Figure 1.
Figure 6
shows schematically a detail of the device according to Figures 1, 4 and 5.

Die Verriegelungseinrichtung 5 wird als Ganzes fest am Blendrahmen 1 montiert, ohne Durchbrüche von außen. Die ganze Einrichtung kann dabei durch ein nicht dargestelltes, insbesondere langgestrecktes Gehäuse zum Rauminneren hin abgedeckt oder aufgenommen sein, wobei lediglich das hier hakenförmige Verriegelungsglied 15 beim Verschwenken in die Verriegelungsstellung aus diesem Gehäuse heraustritt. Alle aktiven Elemente, Motor 6, Verriegelungsglied 15 und ein Kniehebelsystem 8 sind auf der selben Seite angeordnet, hier auf der selben Seite einer Platte 30 dargestellt. Ein entsprechendes Gehäuse zur Aufnahme des Verriegelungsgliedes in der Freigabestellung findet sich in Figur 2.The locking device 5 is fixed as a whole on the frame 1 without Breakthroughs from the outside. The whole facility can not by one shown, in particular elongated housing covered towards the interior or be included, only the hook-shaped locking member 15 here emerges from this housing when pivoting into the locking position. All active elements, motor 6, locking member 15 and a toggle system 8 are on arranged on the same side, shown here on the same side of a plate 30. On corresponding housing for receiving the locking member in the Release position can be found in Figure 2.

Die Verriegelungseinrichtung wirkt auf den Flügel 2 über den Flügelüberschlag 3. Um eine ausreichende Kraft ohne Beschädigung des Flügelrahmens aufbringen zu können, kann an der entsprechenden Kontaktstelle des Flügels eine Widerlagerplatte 4 angebracht werden. Diese kann noch eine besondere Bedeutung dadurch haben, daß durch die Wahl der Dicke der Platte 4 bzw. durch Anbringung einer oder mehrerer Unterlegteile unter die Platte 4 unterschiedliche Überschlagdicken oder dergleichen kompensiert werden können. The locking device acts on the wing 2 via the wing flap 3 to be able to apply sufficient force without damaging the casement, can an abutment plate 4 at the corresponding contact point of the wing be attached. This can have a special meaning in that by choosing the thickness of the plate 4 or by attaching one or more Shims under the plate 4 different rollover thicknesses or the like can be compensated.

Bei der vorliegenden Beschreibung wird davon ausgegangen, daß die Verriegelungseinrichtung elektromotorisch betätigbar ist, wie dies wohl insbesondere bei Fenstern im Oberlichtbereich üblicherweise der Fall ist. Zu diesem Zweck weist die Verriegelungseinrichtung 5 einen Elektromotor 6 auf, der über ein entsprechendes Untersetzungsgetriebe eine Welle 12 antreibt, auf der ein hebelartiges Krafteinleitungselement 13 (vgl. Figur 4) befestigt ist. Eine Fortsetzung der Antriebswelle ist als Zapfen mit 12a bezeichnet.In the present description it is assumed that the Locking device can be actuated by an electric motor, as is probably the case in particular this is usually the case for windows in the skylight area. For this purpose, the Locking device 5 on an electric motor 6, which has a corresponding Reduction gear drives a shaft 12 on which a lever-like Force introduction element 13 (see FIG. 4) is attached. A continuation of the Drive shaft is designated as a pin with 12a.

Zum Heranziehen, Andrücken und Verriegeln des Flügels 2 dient ein hakenförmiges Verriegelungsglied 15, das mittels eines Lagerbockes 10,10b oder 30 am Blendrahmen um eine gegenüber der Achse der Antriebswelle 12 versetzte, zu dieser jedoch parallele Achse 17 in einem eingesetzten Haltestück 11 oder separaten Armen 11a schwenkbar gelagert ist. Im Abstand von der Schwenkachse 17 weist das Verriegelungsglied 15 eine hakenförmige Verriegelungsnase 16 auf, die mit der Widerlagerplatte 4 am Flügelrahmen 2 zusammenwirken kann. Im Abstand von der Schwenkachse 17 und der Verriegelungsnase 16 weist das Verriegelungsglied 15 eine Anlenkstelle 18 für das Anlenkende 20 eines (gebogenen) Kniehebels 14 auf. Das andere Ende 19 des Kniehebels 14 ist an dem freien Ende 22 des hebelartigen Krafteinleitungselementes 13 angelenkt. Die Teile 13,14 und 15 bilden somit ein kniehebelartiges Betätigungssystem 8, in das eine Betätigungskraft über den Elektromotor 6 und seine Welle 12 über einen Eingriff 21,21a eingeleitet werden kann, welche Kraft als Schließ- und Verriegelungskraft von dem hakenförmigen Verriegelungsglied 15 bei Erreichen der Schließstellung (Figur 5) auf den Flügelrahmen 2 übertragen wird.A hook-shaped is used to pull, press and lock the wing 2 Locking member 15, which by means of a bracket 10,10b or 30 on the frame by an offset to the axis of the drive shaft 12, but to this parallel axis 17 in an inserted holding piece 11 or separate arms 11a is pivotally mounted. At a distance from the pivot axis 17, the Locking member 15 has a hook-shaped locking lug 16 which with the Abutment plate 4 can cooperate on the sash 2. At a distance from the Pivot axis 17 and the locking lug 16 has the locking member 15 Articulation point 18 for the articulation end 20 of a (bent) toggle lever 14. The other end 19 of the toggle lever 14 is at the free end 22 of the lever-like Force introduction element 13 articulated. The parts 13, 14 and 15 thus form one toggle-type actuation system 8, in which an actuation force over the Electric motor 6 and its shaft 12 can be initiated via an engagement 21, 21a, what force as the closing and locking force of the hook-shaped Locking member 15 on reaching the closed position (Figure 5) Casement 2 is transmitted.

Das hakenförmige Verriegelungsglied 15 weist auf seiner Rückseite, d. h. auf der von der Verriegelungsnase 16 abgewandten Seite zwischen den Anlenkstellen 17 und 18 eine randoffene Ausnehmung 25 auf. Diese ist so ausgebildet und angeordnet, daß bei der Bewegung in die Freigabestellung das hebelartige Krafteinleitungselement 13 mit seinem auf der Welle 12 befestigten Ende eintauchen kann, wie dies am besten aus Figur 4 ersichtlich ist, wobei man erkennt, daß in der Freigabestellung die Anlenkstellen 17 und 18 und die Antriebswelle 12 praktisch auf einer gemeinsamen Linie zu liegen kommen können.The hook-shaped locking member 15 has on its back, i. H. on the of the side facing away from the locking lug 16 between the articulation points 17 and 18 a recess 25 open to the edge. This is designed and arranged so that at the lever-like force introduction element 13 with the movement into the release position its end attached to the shaft 12 can dip out as best as possible Figure 4 can be seen, it being seen that in the release position Articulation points 17 and 18 and the drive shaft 12 practically on a common Line can come to rest.

Aus Figur 4 ist auch ersichtlich, daß das hakenförmige Verriegelungsglied 15 in der Freigabestellung nahezu vollständig in den Umriß des Elektromotors 6 eintaucht, so daß die Vorrichtung leicht in einem kleinen Gehäuse aufgenommen werden kann, wobei in der Freigabestellung das Verriegelungsglied im Gehäuse verdeckt aufgenommen ist.From Figure 4 it can also be seen that the hook-shaped locking member 15 in the Release position almost completely immersed in the outline of the electric motor 6, so that the device can be easily accommodated in a small housing, wherein in the release position the locking member is hidden in the housing is recorded.

Figur 4 zeigt außerdem zwischen Blendrahmen und Flügelrahmen 2 im Bereich des Überschlages 3 einen Spalt. Die Größe dieses Spaltes setzt sich zusammen aus der Dicke der nicht dargestellten Dichtung und aus einem leichten Abstehen des Flügels 3' am Ende einer Schließbewegung eines (nicht dargestellten) Steuersystems des Flügels. Um den Flügel in eine abdichtende und einbruchssichere Schließstellung zu bringen, wird die Verriegelungseinrichtung betätigt, wobei die Welle 12 das Krafteinleitungselement 13 in Figur 4 im Uhrzeigersinn schwenkt. Über den Kniehebel 14 wird das hakenförmige Verriegelungsglied 15 um seine rahmenfeste Schwenkachse 17 ebenfalls im Uhrzeigersinne verschwenkt. Dabei tritt die Welle 12 aus der Ausnehmung 25 heraus. Die Gelenkverbindung 19,22 zwischen Krafteinleitungselement 13 und Kniehebel 14 wandert zu einem Winkel von mehr als 180° und überschreitet kurz vor der Verriegelungsstellung (Figur 5) die Streck- bzw. Totpunktlage des kniehebelartigen Betätigungssystems 8. Die Totpunktlage ist in Figur 5 durch eine gestrichelte Verbindungslinie T zwischen der Welle 12 und der Gelenkverbindung 18/20 wiedergegeben, während die relative Stellung der betreffenden Gelenke in der Verriegelungsstellung durch die in Figur 5 ausgezeichneten Gelenkstellen bzw. Welle 12, 18/20, 19/22 wiedergegeben ist. Der Winkel α über Strecklage ist etwa 10°, bevorzugt zwischen 10° und 20°.Figure 4 also shows between the frame and sash 2 in the area of Roll over 3 a crack. The size of this gap is made up of the Thickness of the seal, not shown, and a slight protrusion of the wing 3 ' at the end of a closing movement of a (not shown) control system of the Wing. To close the sash in a sealing and burglar-proof closed position bring, the locking device is actuated, the shaft 12 that Force introduction element 13 in Figure 4 pivots clockwise. On the The toggle lever 14 is the hook-shaped locking member 15 around its fixed frame Swivel axis 17 also pivoted clockwise. The shaft 12 occurs out of the recess 25. The articulation 19.22 between Force application element 13 and toggle lever 14 migrates to an angle of more than 180 ° and shortly before the locking position (Figure 5) exceeds the stretching or Dead center position of the toggle-type actuation system 8. The dead center position is in Figure 5 by a dashed line T between the shaft 12 and the Articulated connection shown 18/20, while the relative position of the relevant joints in the locking position by the in Figure 5 excellent joints or shaft 12, 18/20, 19/22 is reproduced. The Angle α above the stretched position is approximately 10 °, preferably between 10 ° and 20 °.

Die Verriegelungsstellung des hakenförmigen Verriegelungsgliedes 15 wird bestimmt dadurch, daß sich das freie Ende des hebelförmigen Krafteinleitungselementes 13 an einer Anschlagfläche 26 des hakenförmigen Verriegelungsgliedes 15 anlegt, wie dies Figur 5 zeigt. Diese Anschlagfläche befindet sich im Bereich der Ausnehmung 25, und zwar in der Nähe des Ausnehmungsrandes auf Seiten der Schwenkachse 17. Die genauere Lage ist nochmals schematisch in Figur 6 wiedergegeben. Damit ist die Verriegelungseinrichtung in ihrer Verriegelungsstellung selbsttätig gegen Öffnen gesperrt, auch wenn der Elektromotor 6 des kniehebelartigen Betätigungssystems 8 bei Erreichen der Verriegelungsstellung, zum Beispiel durch eine elektronische Lastabschaltung, automatisch abgeschaltet und damit stromlos wird.The locking position of the hook-shaped locking member 15 is determined characterized in that the free end of the lever-shaped force introduction element 13 creates a stop surface 26 of the hook-shaped locking member 15, as this Figure 5 shows. This stop surface is in the area of the recess 25, and although near the edge of the recess on the side of the pivot axis 17. Die The more precise location is shown again schematically in FIG. 6. So that's it Locking device in its locking position automatically against opening locked, even if the electric motor 6 of the toggle-type actuation system 8 at Reaching the locking position, for example by an electronic one Load cut-off, automatically switched off and thus de-energized.

Bei Betrachtung der Figur 5 ist ersichtlich, daß bei im Öffnungssinne wirkenden äußeren Kräften auf den Flügel 2 zwar eine Kraft in Richtung Rückschwenkbewegung des Verriegelungsgliedes wirksam wird. Diese Kraft könnte theoretisch über die Anschlagfläche 26 im Öffnungsdrehsinn auf das hebelförmige Krafteinleitungselement 13 einwirken und dieses über die Totpunktlage hinwegschwenken, was dann zu einem leichten Öffnen des Flügels führen könnte. Tatsächlich aber drückt diese äußere Kraft über das Verriegelungsglied 15 die Anlenkstelle 18/20 auf den Kniehebel 14, der wiederum im Verriegelungssinn über die Gelenkstelle 19,22, auf das hebelförmige Krafteinleitungselement 13 einwirkt und so wirksam dieses Element und damit das ganze kniehebelartige Betätigungssystem selbsttätig in der gezeigten Verriegelungsstellung hält oder sperrt, und zwar mit umso größerer Kraft, je größer die von außen wirkenden Kräfte sind.When viewing FIG. 5, it can be seen that those acting in the opening direction external forces on the wing 2 a force in the direction of the pivoting movement of the locking member takes effect. Theoretically, this force could Stop surface 26 in the opening direction on the lever-shaped Force application element 13 act and this over the dead center position swing away, which could lead to a slight opening of the wing. In fact, however, this external force presses the locking member 15 Articulation point 18/20 on the toggle lever 14, which in turn is in the locking direction via the Articulation point 19, 22, acts on the lever-shaped force introduction element 13 and so effective this element and thus the whole toggle-type actuation system automatically holds or locks in the locking position shown, with all the more greater force, the greater the external forces are.

In Figur 3 ist ein abgewandeltes Auführungsbeispiel gezeigt, bei dem zwei Kniehebel 14a vorgesehen sind, die beiderseits des als einfacher Hebel ausgebildeten Krafteinleitungselement 13a angeordnet sind. Bei dem zuvor beschriebenen Ausführungsbeispiel ist nur ein Kniehebel vorgesehen, während das Krafteinleitungselement 13, zweiarmig ausgebildet ist und den Kniehebel zwischen seinen Armen aufnimmt. Im übrigen arbeitet die Vorrichtung nach Figur 3 in gleicher Weise, wie die nach Figur 1. Aus diesem Grunde sind die gleichen Bezugsziffern unter Hinzufügung des Buchstabens "a" verwendet worden.FIG. 3 shows a modified exemplary embodiment, in which two Knee levers 14a are provided, which are designed on both sides of the as a simple lever Force introduction element 13a are arranged. With the previously described Embodiment is provided only one toggle lever, while that Force introduction element 13, is formed with two arms and the toggle lever between his arms. Otherwise, the device according to FIG. 3 operates in the same way Way, like that of Figure 1. For this reason, the same reference numerals are below The addition of the letter "a" has been used.

Der Motor 6 wird mit der Verriegelungseinrichtung zu einer Baueinheit zusammengefügt, was durch eine Winkelplatte 10b,10c gemäß Figur 3, durch ein Gehäuse 10 gemäß Figur 2 oder durch eine Montageplatte 30 gemäß den Figuren 1, 4 und 5 geschehen kann. Der Motor wird hierbei drehfest montiert und ragt mit seiner Welle 12 in den Hebel 13 oder 13a herein, den er in eine Drehbewegung bei Betätigung zu versetzen mag. Die Achse des Motors 12 verläuft parallel zur Achse 17 des Verriegelungsgliedes 15, das gemäß Figur 4 eine Verschwenkbewegung A ausführt, um den dort noch nicht herangezogenen Flügel mit dem strichliniert eingezeichneten Überschlag 3' in die vollständige Schließlage zu überführen. Im Öffnungssinne dreht das Verriegelungsglied 15 entgegen der Richtung A und gibt die Öffnungsrichtung für den Flügel in Richtung x frei, wie in Figur 4 eingezeichnet.The motor 6 becomes a structural unit with the locking device put together what by an angle plate 10b, 10c according to Figure 3, by a Housing 10 according to FIG. 2 or by means of a mounting plate 30 according to FIGS. 1, 4 and 5 can happen. The motor is mounted in a rotationally fixed manner and projects with it Shaft 12 in the lever 13 or 13a, which he in a rotary motion Activity. The axis of the motor 12 runs parallel to the axis 17 of the locking member 15 which, according to FIG. 4, has a pivoting movement A executes to the wing not yet drawn there with the dashed lines to transfer overlap 3 'drawn into the complete closed position. in the Opening sense turns the locking member 15 against the direction A and gives the Opening direction for the wing in direction x freely, as shown in Figure 4.

Bei Verwenden eines Gehäuses mit einem zusätzlichen Steg 11, der eine Lagerstelle für die Achse 17 des Verriegelungsgliedes 15 ist, kann die Achse 12 des Motors 6 doppelt gelagert sein, einmal im Motorgehäuse und ein zweites Mal mit einem Zapfen 12a am freien Ende, der in den dreibeinigen Steg 11 gemäß Figur 2 eingreift.When using a housing with an additional web 11, the bearing for the axis 17 of the locking member 15, the axis 12 of the motor 6 be stored twice, once in the motor housing and a second time with one Pin 12a at the free end, which engages in the three-legged web 11 according to Figure 2.

Der Schwenkwinkel des Verriegelungsgliedes zwischen den beiden Endstellungen (Freigabestellung und Schließstellung) wird durch die vom Motor 6 veranlaßte Drehbewegung des Hebels 13 veranlaßt, wobei diese Drehbewegung mehr als 90°, insbesondere mehr als 180° beträgt. Bei dieser Antriebsdrehung des Hebels betätigt sich das Verriegelungsglied 15 um einen Winkel von im wesentlichen 90°, also deutlich weniger, als der Antriebswinkel des Hebels 13,13a.The pivot angle of the locking member between the two End positions (release position and closed position) are determined by the motor 6 caused rotation of the lever 13 causes this rotation more than 90 °, in particular more than 180 °. With this drive rotation of the lever the locking member 15 is actuated by an angle of essentially 90 °, that is significantly less than the drive angle of the lever 13, 13a.

Die Verriegelungseinrichtung läßt sich, wie aus der vorhergehenden Beschreibung und der Zeichnung hervorgeht, nur entriegeln, wenn der Motor 6 im Öffnungssinn in Betrieb genommen wird. Damit ergibt sich neben einer hohen Andrückkraft zum dichten Verschließen des Flügels auch eine große Einbruchssicherheit.The locking device can, as from the previous description and of the drawing, only unlock when the motor 6 is operating in the opening direction is taken. This results in a high pressure force for sealing Locking the wing also a great security against burglary.

Kleinere Überschlagshöhenunterschiede gleicht die Verriegelungseinrichtung selbsttätig aus. Größere Unterschiede, zum Beispiel ab 2 mm können durch Unterlegen des Lagerbockes 10, der oberhalb des Überschlages anzuordnenden Halteplatte 30 für den Motor 6 oder der Widerlagerplatte 4 oder durch andere Maßnahmen, wie Höhenverstellung, Schrägkeile mit Verzahnung und dergleichen, kompensiert werden. Für die Montage können alle bekannten, das Montieren vereinfachenden Möglichkeiten eingesetzt werden, was für den Fachmann ohne weiteres einleuchtend ist und daher nicht näher erläutert zu werden braucht.The locking device compensates for smaller differences in rollover heights automatically. Larger differences, for example from 2 mm, can be underlaid of the bearing block 10, the holding plate 30 to be arranged above the rollover for the motor 6 or the abutment plate 4 or by other measures, such as Height adjustment, inclined wedges with teeth and the like can be compensated. All known, simplifying assembly options can be used for assembly are used, which is obvious to the person skilled in the art and therefore need not be explained in more detail.
