Die Aufgabe wird gelöst durch eine Verriegelungseinrichtung für, insbesondere elektrische, Geräte, insbesondere Waschmaschinen, mit einem Verriegelungsschieber und mit einem Antrieb für den Verriegelungsschieber, so dass mittels des Antriebs der Verriegelungsschieber, linear, bewegbar ist, wobei bei Betätigung des Antriebs der Verriegelungsschieber in Eingriff mit einem Schließkörper, insbesondere Schließhaken, bringbar ist und in einer Verriegelungsposition der Schließkörper den Verriegelungsschieber hintergreift, wobei in der Verriegelungsposition der Verriegelungsschieber mittels des am Verriegelungsschieber angreifenden Schließkörpers mit einer vorbestimmten Kraft beaufschlagt ist, wobei der Verriegelungsschieber in der Verriegelungsposition um eine quer zur Kraft des angreifenden Schließkörpers ausgebildeten Schwenkachse gelagert ist und der Verriegelungsschieber gegen ein Verschwenken mittels einer Schwenkblockiereinrichtung blockiert ist, wobei für eine oder bei einer Notentriegelung der Verriegelungseinrichtung die Schwenkblockiereinrichtung für den Verriegelungsschieber gelöst wird, so dass in Folge des am Verriegelungsschieber angreifenden Schließkörpers der Verriegelungsschieber aus der Verriegelungsposition verschwenkt wird.The object is achieved by a locking device for, in particular electrical, devices, in particular washing machines, with a locking slide and with a drive for the locking slide, so that by means of the drive of the locking slide, linear, is movable, wherein upon actuation of the drive of the locking slide into engagement with a closing body, in particular closing hook, can be brought and engages behind the locking slide in a locking position of the closing body, wherein in the locking position of the locking slide by means of acting on the locking slide Locking body is acted upon by a predetermined force, wherein the locking slide is mounted in the locking position to a transverse to the force of the attacking closing body pivot axis and the locking slide is blocked against pivoting by means of a pivot blocking device, wherein for one or in an emergency unlocking of the locking device, the pivot blocking device for the locking slide is released, so that is pivoted out of the locking position as a result of acting on the locking slide closing body of the locking slide.

Die Erfindung beruht auf dem Gedanken, dass eine Verriegelungseinrichtung als ein motorisch beschriebenes Schloss auf einfache Weise und zerstörungsfrei in der Verriegelungsposition notentriegelt wird, wodurch eine schnelle Wiederinbetriebnahme der Verriegelungseinrichtung gewährleistet ist. Hierbei wird mittels eines, vorzugsweise elektrischen, Antriebsmotors ein Verriegelungsschieber aus einer Öffnungsstellung in eine Verriegelungsposition gebracht, wobei der Verriegelungsschieber hierbei mit einem Schließkörper in Eingriff gebracht wird. In der Verriegelungsposition ist dabei der Verriegelungsschieber verschwenkbar gelagert, wobei zur Verriegelung der Verriegelungsschieber gegen ein Verschwenken blockiert gehalten ist. Hierbei wird der Schließkörper durch Beaufschlagen mit einer Haltekraft gegen eine Vorspannkraft in der Verriegelungsposition gehalten, so dass der mit einer Vorspannkraft beaufschlagte Schließkörper mit dem verschwenkbaren Verriegelungsschieber in Eingriff gehalten wird.The invention is based on the idea that a locking device is unlocked as a motor-described lock in a simple manner and non-destructive in the locked position, whereby a quick restart of the locking device is ensured. In this case, a locking slide is brought from an open position to a locking position by means of a, preferably electric, drive motor, wherein the locking slide is in this case brought into engagement with a closing body. In the locking position while the locking slide is pivotally mounted, being held blocked for locking the locking slide against pivoting. In this case, the closing body is held by applying a holding force against a biasing force in the locking position, so that the acted upon by a biasing force closing body is held in engagement with the pivotable locking slide.

Zur Notentriegelung wird die Schwenkblockiereinrichtung, die in der Verriegelungsposition am Verriegelungsschieber angreift, gelöst, wodurch, in Folge der Vorspannkraft des Schließkörpers der in der Verriegelungsposition entblockierte Verriegelungsschieber geschwenkt wird, wodurch der Eingriff des Schließkörpers am Verriegelungsschieber gelöst wird und die Verriegelungseinrichtung notentriegelt wird oder ist. Der Verriegelungsschieber wird dabei um eine Achse gedreht, die quer, insbesondere senkrecht, zur Richtung der Vorspannkraft ausgebildet ist.For emergency unlocking, the pivotal blocking device, which engages in the locking position on the locking slide, released, whereby, pivoted due to the biasing force of the closing body of the unblocked in the locking position locking slide is, whereby the engagement of the closing body is released on the locking slide and the locking device is unlocked or is. The locking slide is thereby rotated about an axis which is formed transversely, in particular perpendicular, to the direction of the biasing force.

Darüber hinaus ist in einer Ausgestaltung der Verriegelungseinrichtung vorgesehen, dass in der Verriegelungsposition mittels der Schwenkblockiereinrichtung ein Gegendrehmoment auf den Verriegelungsschieber ausgeübt ist oder wird, wobei das Gegendrehmoment dem durch den Schließkörper bewirkten Drehmoment entgegenwirkt.In addition, in one embodiment of the locking device is provided that in the locking position by means of the pivotal blocking device a counter-torque is exerted on the locking slide or is, the counter torque counteracts the torque caused by the closing body.

In this case, the projection 19 has a sloping or inclined plane, so that upon locking of the locking device 10, the tip of the projection 19 engages behind the hook-shaped nose of the closing hook 22, so that the nose of the closing hook 22 along the ramp-shaped surface of the projection 19 slides and after Overcoming a, preferably designed as a retaining shoulder, increase 17 of the locking bolt 18 is arranged in a retaining groove 28 of the locking bolt 18.

In Fig. 1b ist der Schließzustand der Verriegelungseinrichtung 10 gezeigt, wobei der Schließhaken 22 mit einer vorbestimmten Vorspannkraft im Eingriff mit der Halterille 28 des Verriegelungsbolzens 18 angeordnet ist. In der verriegelten Position wird der mit einer Vorspannkraft beaufschlage Schließhaken 22 durch eine am Schließhaken 22 vorhandene Zugkraft oder Vorspannkraft festgehalten, wobei die Zugkraft beispielsweise durch die Federwirkung einer Türdichtung bewirkt wird. Der Verriegelungsbolzen 18 stützt sich dabei am Anschlagblock 20 ab, wobei der Anschlagblock 20 selbst an der Innenwandung 11 abgestützt ist. Hierbei sind die Verbindungen des Anschlagblocks 20 zum Verriegelungsbolzen 18 und zur Innenwandung 20 ausschließlich kraftschlüssig und reibkraftschlüssig ausgebildet.In Fig. 1b the closure state of the locking device 10 is shown, wherein the locking hook 22 is arranged with a predetermined biasing force in engagement with the retaining groove 28 of the locking bolt 18. In the locked position of the applied with a biasing force closing hook 22 by an am Locking hook 22 existing traction or preload held, the tensile force is effected for example by the spring action of a door seal. The locking pin 18 is supported on the stop block 20, wherein the stop block 20 itself is supported on the inner wall 11. Here, the connections of the stop block 20 to the locking pin 18 and the inner wall 20 are formed exclusively frictionally and frictionally engaged.

Um eine Notentriegelung des verriegelten Schließhakens 22 auszuführen (vgl. Fig. 1c), wird der Anschlagblock 20 zwischen dem Verriegelungsbolzen 18 und dem Schließhaken 22 durch seitliches Verschieben entfernt, bis zwischen dem Anschlagblock 20 und dem Verriegelungsbolzen 18 kein Kontakt mehr vorhanden ist bzw. bis keine gemeinsame Kontaktfläche zwischen Anschlagblock 20 und dem Verriegelungsbolzen 18 vorhanden ist. Hierdurch wird der Kraftschluss zwischen dem Anschlagblock 20 und dem Verriegelungsbolzen 18 aufgehoben.In order to carry out an emergency unlocking of the locked closing hook 22 (cf. Fig. 1c ), the stopper block 20 between the locking pin 18 and the locking hook 22 is removed by lateral displacement until between the stop block 20 and the locking pin 18 no contact is present or until no common contact surface between the stop block 20 and the locking pin 18 is present. As a result, the frictional connection between the stop block 20 and the locking pin 18 is released.

Durch die Entfernung des Anschlagblocks 20 (vgl. Fig. 1c) wird in Folge der Krafteinwirkung des Schließhakens 22 am bzw. auf der Gewindestange 16 drehbar gelagerten Verriegelungsbolzen 18 ein Drehmoment auf den Verriegelungsbolzen 18 bewirkt, wodurch mittels des zur Gewindestange 16 als Drehachse des Verriegelungsbolzens 18 asymmetrisch in der Halterille 28 angeordneten Schließhakens 22 aufgrund der Zugkraft am Schließhaken 22 ein Drehmoment auf den entblockierten Verriegelungsbolzen 18 ausgeübt wird. Unter der Einwirkung des Drehmoments wird der Verriegelungsbolzen 18 soweit verdreht, bis der Schließhaken 22 vom Verriegelungsbolzen 18 gelöst ist und durch die Öffnung 13 aus der Verriegelungseinrichtung 10 herausgezogen wird.By the removal of the stop block 20 (see. Fig. 1c ) is due to the force of the locking hook 22 on or on the threaded rod 16 rotatably mounted locking bolt 18 causes a torque on the locking pin 18, whereby by means of the threaded rod 16 as the axis of rotation of the locking bolt 18 asymmetrically arranged in the retaining groove 28 closing hook 22 due to the tensile force on the locking hook 22, a torque is exerted on the unblocked locking bolt 18. Under the action of the torque of the locking pin 18 is rotated until the locking hook 22 is released from the locking pin 18 and is pulled out through the opening 13 of the locking device 10.

Um die Verriegelungseinrichtung 10 in einen betriebsbereiten Öffnungszustand (vgl. Fig. 1a) zu bringen, werden der Verriegelungsbolzen 18 und der Anschlagblock 20 in die Ausgangsstellung (vgl. Fig. 1a) durch Ausführung von reversiblen Bewegungsvorgängen gebracht.To lock the locking device 10 in an operative opening state (see. Fig. 1a ), the locking pin 18 and the stop block 20 are in the starting position (see. Fig. 1a ) by performing reversible motions.

Durch die erfindungsgemäße Ausgestaltung der Verriegelungseinrichtung 10 wird eine schnelle Wiederinbetriebnahme der Verriegelungseinrichtung 10 erreicht, wobei hierfür keine Wiederherstellungskosten entstehen, da die Notentriegelung der Verriegelungseinrichtung zerstörungsfrei durchgeführt wird. Darüber hinaus ist auch keine besondere und komplizierte Schlussmechanik erforderlich.The inventive design of the locking device 10, a quick restart of the locking device 10 is achieved, for which no recovery costs arise because the emergency release of the locking device is carried out non-destructive. In addition, no special and complicated closing mechanism is required.
