Description

Die Erfindung bezieht sich auf eine Verriegelungseinrichtung mit einer Klinkensperre für grifflose Schwenkschiebetüren, die mittels eines über Umlenkrollen laufenden, in sich geschlossenen Bandes in Form eines Seiles, Keil- oder Zahnriemens, einer Kette od.dgl. von einem Motor angetrieben sind.The invention relates to a locking device with a pawl lock for handle-less pivoting sliding doors, or the like by means of a self-contained band running over deflection rollers in the form of a rope, V-belt or toothed belt, a chain or the like. are powered by a motor.

Es wurden bereits Vorschläge gemacht, wie bei grifflosen Schwenkschiebetüren die Verriegelung im geschlossenen Zustand der Tür entriegelt werden kann. Eine Lösung, mit mechanischen Mitteln mittels eines Druckknopfes diese Verriegelung vorzunehmen, ist gescheitert. Eine weitere Möglichkeit, die Entriegelung mittels eines Magneten vorzunehmen, hat sich nicht bewährt, weil verhältnismäßig große Entriegelungskräfte erforderlich sind und der Raum für die Unterbringung eines hinreichend großen Elektromagneten nicht vorhanden ist.Suggestions have already been made as to how the lock can be unlocked when the door is closed without a handle. A solution to make this locking by mechanical means by means of a push button has failed. Another possibility of unlocking by means of a magnet has not proven itself, because relatively large unlocking forces are required and the space for accommodating a sufficiently large electromagnet is not available.

Der Erfindung liegt der Gedanke zugrunde, die Entriegelung über den Antrieb der Tür vorzunehmen, was den Vorteil hat, daß der Antriebsmotor genügend Kraft hat, um zusätzlich zur Öffnungsbewegung auch noch die Entriegelung durchzuführen.The invention is based on the idea of performing the unlocking via the drive of the door, which has the advantage that the drive motor has sufficient power to carry out the unlocking in addition to the opening movement.

Erfindungsgemäß wird daher bei Verriegelungseinrichtungen der eingangs erwähnten Art das Ziel dadurch erreicht, daß die in eine ortsfest angeordnete Rast eingreifende Klinke aus einem Winkelhebel besteht, welcher an einer am Band sitzenden Klemme schwenkbar gelagert ist und der eine Arm des Hebels die Gegenrast aufweist und der andere Arm gelenkig mit dem gegenüber der Klemme in Bandrichtung verschiebbaren Türblatt verbunden ist, wobei beim Öffnungsvorgang die gegenüber dem Türblatt voreilende Klemme den Winkelhebel entgegen der Kraft einer Feder verschwenkt und die Klinkensperre löst.According to the invention, the aim is achieved in locking devices of the type mentioned above in that the pawl engaging in a fixedly arranged catch consists of an angle lever which is pivotally mounted on a clamp seated on the band and one arm of the lever has the counter-catch and the other Arm articulated with the opposite of the clamp in the direction of the strap Slidable door leaf is connected, wherein during the opening process, the terminal that leads the door leaf pivots the angle lever against the force of a spring and releases the pawl lock.

Die Erfindung bezieht sich ferner auf bauliche Ausgestaltungen, vor allem im Zusammenhang mit einer Notbetätigungseinrichtung.The invention further relates to structural designs, especially in connection with an emergency actuation device.

In der Zeichnung ist der Gegenstand der Erfindung in einer beispielsweisen Ausführungsform dargestellt. Es zeigen Fig. 1 eine Ansicht der Verriegelungseinrichtung von vorne und Fig. 2 eine Ansicht in Richtung des Pfeiles A in Fig. 1.In the drawing, the subject matter of the invention is shown in an exemplary embodiment. 1 shows a view of the locking device from the front and FIG. 2 shows a view in the direction of arrow A in FIG. 1.

Im dargestellten Beispiel handelt es sich um eine Schwenkschiebetür mit zwei Türblättern, die nicht dargestellt sind. Ein Band 1, vorzugsweise aus einem Zahnriemen bestehend, ist beiderseits des Türrahmens über Umlenkrollen geführt und in sich geschlossen. Eine der Umlenkrollen ist von einem Elektromotor über ein Getriebe in beiden Drehrichtungen antreibbar. Am oberen Trum des Bandes 1 sitzt eine Klemme 2, die mit einer Achse 3 versehen ist, auf der ein zweiarmiger Hebel 4 schwenkbar angeordnet ist. Der eine Arm 5 ist mit einer Rolle 6 versehen und der andere Arm 7 ist in einem Träger 8 schwenkbar gelagert, welcher mit dem nicht dargestellten Türblatt fest verbunden ist. Der Träger 8 ist mit einer Konsole 9 versehen, welche eine Achse 10 trägt, an der der Arm 7 angelenkt ist. Eine Drehfeder 11 stützt sich einerseits am Träger und anderseits auf der Klemme 2 ab und versucht, den Winkelhebel 4 entgegen dem Uhrzeigerdrehsinn zu verschwenken. Der Winkelhebel 3 unterfaßt die Konsole 9 mittels eines Vorsprunges 12, der die eine Endlage des Winkelhebels bestimmt. Entgegen der Kraft dieser Drehfeder kann der Winkelhebel 4 im Uhrzeigerdrehsinn verschwenkt werden, wobei eine Schulter 13 die andere Endlage des Winkelhebels 4 bestimmt.In the example shown, it is a pivoting sliding door with two door leaves, which are not shown. A band 1, preferably consisting of a toothed belt, is guided on both sides of the door frame via deflection rollers and is self-contained. One of the deflection rollers can be driven by an electric motor via a gear in both directions of rotation. On the upper run of the belt 1 there is a clamp 2, which is provided with an axis 3 on which a two-armed lever 4 is pivotably arranged. One arm 5 is provided with a roller 6 and the other arm 7 is pivotally mounted in a carrier 8 which is firmly connected to the door leaf, not shown. The carrier 8 is provided with a bracket 9 which carries an axis 10 on which the arm 7 is articulated. A torsion spring 11 is supported on the one hand on the support and on the other hand on the clamp 2 and tries to pivot the angle lever 4 counterclockwise. The angle lever 3 frames the bracket 9 by means of a projection 12 which determines the one end position of the angle lever. Contrary to the force of this torsion spring, the angle lever 4 can be pivoted clockwise, a shoulder 13 determining the other end position of the angle lever 4.

Am nicht dargestellten Türrahmen sitzt eine Grundplatte 14, auf der mittels einer Achse 15 ein Hebel 16 schwenkbar gelagert ist. Auch dieser Arm 16 steht unter der Wirkung einer Drehfeder 17, die sich einerseits am Arm und anderseits an einem Stift 18 mit ihren Enden abstützt. Diese Feder 17 versucht, den Arm 16 entgegen dem Uhrzeigerdrehsinn zu verschwenken. Die Endlage des Schwenkbereiches wird dadurch bestimmt, daß der Arm eine Schulter 19 aufweist, die sich gegen den Bund 20 eines Notbetätigungshebels 21 anlegt.A base plate 14 sits on the door frame, not shown, on which a lever 16 is located by means of an axis 15 is pivotally mounted. This arm 16 is also under the action of a torsion spring 17, which is supported on the one hand on the arm and on the other hand on a pin 18 with its ends. This spring 17 tries to pivot the arm 16 counterclockwise. The end position of the swivel range is determined in that the arm has a shoulder 19 which bears against the collar 20 of an emergency operating lever 21.

Der Arm 16 weist eine weitere Schulter 22 auf, in deren Schwenkbereich eine Gegenschulter 23 des Entriegelungshebels 21 aus- und einschwenkbar ist.The arm 16 has a further shoulder 22, in the pivoting area of which a counter shoulder 23 of the unlocking lever 21 can be pivoted out and in.

Gemäß Fig. 1 ist die Tür geschlossen und verriegelt. Zum Öffnen der Tür wird mittels eines Druckknopfes der Motor eingeschaltet, wodurch sich das obere Trum des Bandes 1 in Richtung des Pfeiles B bewegt. Zunächst bleibt das Türblatt mit dem Träger 8 stehen, so daß sich der Doppelhebel 4 im Uhrzeigerdrehsinn um die Achse 10 verschwenken muß. Dadurch gelangt die Rolle 6 als Gegenrast außer Berührung mit der ortsfesten Rast 24 des Armes 16; die Tür ist nunmehr entriegelt.1, the door is closed and locked. To open the door, the motor is switched on by means of a push button, as a result of which the upper run of the belt 1 moves in the direction of the arrow B. First, the door leaf with the support 8 remains, so that the double lever 4 has to pivot clockwise about the axis 10. As a result, the roller 6 comes as a counter-catch out of contact with the fixed catch 24 of the arm 16; the door is now unlocked.

Beim Schließen der Tür befindet sich der Winkelhebel 4 gegenüber der Klemme 3 und dem Träger 8 in der dargestellten Lage, wo der Vorsprung 12 die Konsole 9 untergreift. Sobald die Gegenrast 6 auf die Rast 24 des Hebels 16 stößt, wird der Winkelhebel 4 neuerlich verschwenkt, worauf der Verriegelungsvorgang beendet ist, sobald das Türblatt die Geschlossenstellung erreicht hat.When the door is closed, the angle lever 4 is opposite the clamp 3 and the support 8 in the position shown, where the projection 12 engages under the bracket 9. As soon as the counter-catch 6 hits the catch 24 of the lever 16, the angle lever 4 is pivoted again, whereupon the locking process is ended as soon as the door leaf has reached the closed position.

Wird eine Notbetätigungseinrichtung vorgesehen, so befindet sich diese in der in Fig. 1 dargestellten Lage, bei der die Schulter 22 sich auf die Gegenschulter 23 abstützt. Soll bei einem Versagen des Türantriebes die Tür geöffnet werden, so genügt es, den Entriegelungshebel 21 entgegen der Kraft einer Feder 25 im Uhrzeigerdrehsinn zu verschwenken, z.B. mit Hilfe eines Bowdenzuges und die Gegenschulter 23 gibt die Schulter 22 frei. Der Arm 16 verbleibt jedoch unter der Wirkung der Feder 17 in der gezeichneten Lage. Wird die Tür nun von Hand aus geöffnet, so klinken sich Rast und Gegenrast aus, weil die Kraft an der Gegenrast ein Drehmoment auf den Arm 16 bewirkt, das entgegen der Kraft der Feder 17 ein Verschwenken des Armes 16 im Uhrzeigerdrehsinn hervorruft.If an emergency actuation device is provided, it is in the position shown in FIG. 1, in which the shoulder 22 is supported on the counter shoulder 23. If the door is to be opened if the door drive fails, it is sufficient to pivot the unlocking lever 21 counterclockwise against the force of a spring 25, for example with the aid of a Bowden cable, and the counter shoulder 23 releases the shoulder 22. However, the arm 16 remains under the action of the spring 17 in the drawn position. If the door is now opened by hand, the catch and counter-catch release, because the force on the counter-catch causes a torque on the arm 16, which, contrary to the force of the spring 17, causes the arm 16 to pivot in the clockwise direction.

Der Entriegelungshebel 21 kann jederzeit wieder in seine Ausgangslage zurückkehren und den Arm 16 festsetzen.The unlocking lever 21 can return to its starting position at any time and fix the arm 16.

Wird ein zeites Türblatt vorgesehen, so sitzt die zugehörige Klemme am unteren Trum des Bandes 1 und weisen Winkelhebel und Arm die in Fig. 1 dargestellten Formen auf. Die Wirkungsweise ist entsprechend der bereits beschriebenen Einrichtung.If a timely door leaf is provided, the associated clamp sits on the lower run of the hinge 1 and has the angle lever and arm in the shapes shown in FIG. 1. The mode of operation is in accordance with the device already described.

Für die Lage der Türblätter bzw. der Notbetätigungseinrichtung können Überwachungsorgane in Form von Endschaltern vorgesehen sein.Monitoring devices in the form of limit switches can be provided for the position of the door leaves or the emergency actuation device.
