Im Stand der Technik sind Verriegelungsvorrichtungen bekannt, wobei Verriegelungsvorrichtungen dort eingesetzt werden, wo Maschinenteile oder Anlagenteile, z.B. Türen oder Klappen, in einer bestimmten Position verriegelt werden.Locking devices are known in the prior art, with locking devices being used where machine parts or system parts, for example doors or flaps, are locked in a specific position.

Beispielsweise werden Verriegelungsvorrichtungen auch in Waschmaschinen eingesetzt.For example, locking devices are also used in washing machines.

In DE 10 2012 204 490 B4 ist ein Vorverriegelungsmechanismus für ein motorisch betätigtes Verriegelungssystem und ein Verriegelungssystem beschrieben.In DE 10 2012 204 490 B4 a pre-locking mechanism for a motor-operated locking system and a locking system is described.

Außerdem offenbart DE 603 16 237 T2 eine Vorrichtung zur Verriegelung der Tür einer Waschmaschine.Also revealed DE 603 16 237 T2 a device for locking the door of a washing machine.

Darüber hinaus ist in EP 1 826 309 B1 ein Verschluss für die Tür einer Vorrichtung mit Drehtrommel beschrieben. Des Weiteren zeigt EP 0 439 849 B1 eine Türverriegelungsvorrichtung mit schneller Verriegelung und verzögerter Entriegelung, insbesondere für eine Waschmaschine.Furthermore, in EP 1 826 309 B1 a closure for the door of a device with a rotating drum is described. Furthermore shows EP 0 439 849 B1 a door locking device with quick locking and delayed unlocking, especially for a washing machine.

Ferner ist in DE 10 2017 128 301 B1 eine gattungsgemäße Verriegelungsvorrichtung mit einem linear bewegbaren Verriegelungsstift und einem linear bewegbaren Stößel für den Verriegelungsstift, wobei der Stößel mittels einer Spanneinrichtung mit dem Verriegelungsstift verbunden ist, beschrieben. Hierbei weist die Spanneinrichtung zwei in Reihe hintereinander angeordnete Federn auf.Furthermore, in DE 10 2017 128 301 B1 a generic locking device with a linearly movable locking pin and a linearly movable plunger for the locking pin, the plunger being connected to the locking pin by means of a clamping device, is described. Here, the tensioning device has two springs arranged in a row one behind the other.

Eine Aufgabe der Erfindung besteht darin, eine, vorzugsweise alternative, Verriegelungsvorrichtung, z.B. für Waschmaschinen, bereitzustellen, wobei die Verriegelungsvorrichtung kleinbauend sein soll und eine zuverlässige Verriegelung, z.B. eine Tür oder Klappe, ermöglichen soll.An object of the invention is to provide a, preferably alternative, locking device, for example for washing machines, whereby the locking device should be small in size and should enable reliable locking, for example a door or flap.

Gelöst wird die Aufgabe durch eine Verriegelungsvorrichtung für, insbesondere elektrische, Geräte, insbesondere Waschmaschinen, mit einem linear bewegbaren Verriegelungsstift und einem linear bewegbaren Stößel für den Verriegelungsstift, wobei der Stößel mittels einer Spanneinrichtung mit dem Verriegelungsstift verbunden ist, der dadurch weitergebildet ist, dass die Spanneinrichtung zwei koaxial angeordnete Federn aufweist, wobei eine erste innere Feder der Spanneinrichtung von einer zweiten äußeren Feder der Spanneinrichtung wenigstens teilweise umgeben ist.The task is solved by a locking device for, in particular electrical, devices, in particular washing machines a linearly movable locking pin and a linearly movable plunger for the locking pin, the plunger being connected to the locking pin by means of a tensioning device, which is further developed in that the tensioning device has two coaxially arranged springs, a first inner spring of the tensioning device being supported by a second outer one Spring of the tensioning device is at least partially surrounded.

Die Erfindung beruht auf dem Gedanken, dass die Verriegelungsvorrichtung eine Spanneinrichtung zwei ineinander und koaxial zueinander angeordneter Federn aufweist, wodurch sich eine kompakte Anordnung der inneren (ersten) Feder und der äußeren (zweiten) Feder ergibt. Somit wird eine kompakte Verriegelungsvorrichtung ermöglicht. Dadurch, dass die Verriegelungsvorrichtung wenig Bauraum erfordert, ist es vorteilhafterweise möglich, die Verriegelungsvorrichtung in zahlreiche und gegebenenfalls verschiedene Geräte, wie z.B. Waschmaschinen, einzubauen. Durch die kleinbauende Verriegelungsvorrichtung lassen sich auch unterschiedliche Geräte oder Maschinen mit erfindungsgemäßen Verriegelungseinrichtungen für Türen oder dergleichen ausrüsten bzw. nachzurüsten.The invention is based on the idea that the locking device has a tensioning device of two springs arranged inside one another and coaxially to one another, which results in a compact arrangement of the inner (first) spring and the outer (second) spring. This enables a compact locking device. Because the locking device requires little installation space, it is advantageously possible to install the locking device in numerous and possibly different devices, such as washing machines. Thanks to the small locking device, different devices or machines can also be equipped or retrofitted with locking devices according to the invention for doors or the like.

Unter Verwendung der erfindungsgemäßen Spanneinrichtung sind der, vorzugsweise linear bewegbare, Stößel und der, vorzugsweise linear bewegbare, Verriegelungsstift, ausschließlich miteinander, insbesondere mechanisch, gekoppelt. Insbesondere sind die Bewegungsrichtung des, vorzugsweise stiftförmigen oder zylinderförmigen, Stößels und die Bewegungsrichtung des Verriegelungsstifts kollinear, so dass beispielsweise durch eine lineare Bewegung des Stö-ßels der Verriegelungsstifte linear bewegt wird oder bewegbar ist.Using the clamping device according to the invention, the preferably linearly movable plunger and the preferably linearly movable locking pin are coupled exclusively to one another, in particular mechanically. In particular, the direction of movement of the, preferably pin-shaped or cylindrical, plunger and the direction of movement of the locking pin are collinear, so that, for example, the locking pins are moved or can be moved linearly by a linear movement of the plunger.

Ferner ist die Spanneinrichtung zwischen dem Stößel und dem Verriegelungsstift vorgespannt. Der Stößel ist insbesondere stiftförmig bzw. zylinderförmig und mit einem kreisrunden Querschnitt ausgebildet.Furthermore, the tensioning device is prestressed between the plunger and the locking pin. The plunger is in particular pin-shaped or cylindrical and with a circular cross section.

Im verriegelten Zustand der Verriegelungsvorrichtung greift der Verriegelungsstift in einen zu verriegelnden Verriegelungskörper, z.B. eines Türschlosses, ein.When the locking device is locked, the locking pin engages in a locking body to be locked, for example a door lock.

Gemäß einer bevorzugten Ausgestaltung der Verriegelungsvorrichtung ist vorgesehen, dass ein Ende des Stößels mit der Spanneinrichtung mit den koaxial angeordneten Federn in einer Aufnahmekammer des Verriegelungsstifts angeordnet ist.

As a result, one end of the plunger and the clamping device are positioned in the locking pin.

Insbesondere sind in einer Weiterbildung die erste innere Feder der Spanneinrichtung und die zweite äußere Feder der Spanneinrichtung mechanisch voneinander entkoppelt.In particular, in a further development, the first inner spring of the tensioning device and the second outer spring of the tensioning device are mechanically decoupled from one another.

Dazu ist in Ausführung der Verriegelungsvorrichtung vorgesehen, dass die erste innere Feder und die zweite äußere Feder konzentrisch zum Stößel und/oder zur Bewegungsachse des Stößels angeordnet sind, wobei insbesondere die erste innere Feder und die zweite äußere Feder den Stößel umgeben.For this purpose, it is provided in the design of the locking device that the first inner spring and the second outer spring are arranged concentrically to the plunger and / or to the axis of movement of the plunger, with in particular the first inner spring and the second outer spring surrounding the plunger.

Des Weiteren zeichnet sich die Verriegelungsvorrichtung in einer Ausgestaltung dadurch aus, dass zwischen der ersten inneren Feder und der zweiten äußeren Feder ein, insbesondere hülsenartiger, Kopplungskörper angeordnet ist.Furthermore, in one embodiment, the locking device is characterized in that a, in particular sleeve-like, coupling body is arranged between the first inner spring and the second outer spring.

Dazu ist vorteilhafterweise weiter vorgesehen, dass die erste innere Feder zwischen dem Stößel und dem Kopplungskörper angeordnet ist und/oder die zweite äußere Feder zwischen dem Kopplungskörper und dem den Stößel umgebenden Verriegelungsstift angeordnet ist.

Am Stößel 16 ist im Inneren des Hubmagneten 12 ein Anker 14 angeordnet. Der Stößel 16 durchsetzt den bistabilen Hubmagneten 12, wobei bei Bestromung der jeweils endseitigen Spulen des bistabilen Hubmagneten 12 der Stößel 16 mittels den im Hubmagneten 12 bewegbaren Ankern 14 zwischen den Endlagen hin und her bewegt wird. Bei der in Fig. 2 dargestellten Position des Stößels 16 bzw. des Ankers 14 ist dieser in seiner oberen Endlage angeordnet. Insbesondere ist der Hubmagnet 12 als Umkehrhubmagnet ausgebildet.The locking device 10 is, for example, in a housing (not shown here). The locking device 10 has a bistable lifting magnet 12, which is used as a drive or lifting drive for a linearly movable plunger 16. An armature 14 is arranged on the plunger 16 inside the lifting magnet 12. The plunger 16 passes through the bistable lifting magnet 12, whereby when the end coils of the bistable lifting magnet 12 are energized, the plunger 16 is moved back and forth between the end positions by means of the armatures 14 movable in the lifting magnet 12. At the in Fig. 2 shown position of the plunger 16 or the armature 14, this is arranged in its upper end position. In particular, the lifting magnet 12 is designed as a reversing lifting magnet.

Außerhalb des bistabilen Hubmagneten 12 ist ein Ende des Stößels 16 im Innern eines Verriegelungsstiftes 18 angeordnet, wobei der Stößel 16 im Verriegelungsstift 18 teilweise aufgenommen ist. Der Stößel 16 ist hierbei zur Betätigung des Verriegelungsstifts 18 vorgesehen.Outside the bistable lifting magnet 12, one end of the plunger 16 is arranged inside a locking pin 18, the plunger 16 being partially accommodated in the locking pin 18. The plunger 16 is intended to actuate the locking pin 18.

Der Verriegelungsstift 18 ist an dem vom bistabilen Hubmagneten 12 abgewandten Ende mit einem frontseitigen Verriegelungszapfen 20 ausgebildet, der in eine Verriegelungsnut 22 eines drehbaren Drehsegments 24 zum Verriegeln eines Türhakens 26 (vgl. Fig. 1) eingreift. Hierbei ist der Türhaken 26 einer (hier nicht dargestellten) Tür drehbar gelagert und wird in eine Türhakenaufnahme 28 des Drehsegments 24 eingebracht.The locking pin 18 is formed at the end facing away from the bistable lifting magnet 12 with a front locking pin 20, which fits into a locking groove 22 of a rotatable rotary segment 24 for locking a door hook 26 (cf. Fig. 1 ) intervenes. Here, the door hook 26 of a door (not shown here) is rotatably mounted and is inserted into a door hook receptacle 28 of the rotating segment 24.

In Fig. 1 ist das Drehsegment 24 in einer entriegelten Position angeordnet. In Fig. 2 ist das Drehsegment 24 in einer Verriegelungsposition angeordnet.In Fig. 1 the rotary segment 24 is arranged in an unlocked position. In Fig. 2 the rotary segment 24 is arranged in a locking position.

Im Inneren des Verriegelungsstiftes 18 ist das darin aufgenommene Ende des Stößels 16 von einer ersten Druckfeder 30 und einer zweiten Druckfeder 32 umgeben, wobei die erste Druckfeder 30 und die zweite Druckfeder 32 koaxial angeordnet sind und die erste innere Druckfeder 30 von der zweiten äußeren Druckfeder 32 umgeben ist.Inside the locking pin 18 is what is contained therein End of the plunger 16 is surrounded by a first compression spring 30 and a second compression spring 32, the first compression spring 30 and the second compression spring 32 being arranged coaxially and the first inner compression spring 30 being surrounded by the second outer compression spring 32.

Zwischen der ersten Druckfeder 30 und der zweiten Druckfeder 32 ist ein hülsenartiger Kopplungskörper 34 angeordnet, wodurch die erste Druckfeder 30 und die zweite Druckfeder 32 voneinander getrennt sind. Der Kopplungskörper 34 ist zwischen den Druckfedern 30 und 32 angeordnet, wobei die mit dem Kopplungskörper 34 in Kontakt stehenden Federn 30, 32 der Kopplungskörper 34 linear beweglich relativ zum Verriegelungsstift 18 angeordnet sind.A sleeve-like coupling body 34 is arranged between the first compression spring 30 and the second compression spring 32, whereby the first compression spring 30 and the second compression spring 32 are separated from one another. The coupling body 34 is arranged between the compression springs 30 and 32, the springs 30, 32 of the coupling body 34 which are in contact with the coupling body 34 being arranged to be linearly movable relative to the locking pin 18.

Für die innere Druckfeder 30 ist am Stößel 16 ein oberer, endseitiger Sicherungsring 36, der dem Hubmagneten 12 zugewandt, als Anschlag für die innere Feder 30 ausgebildet, so dass die innere Druckfeder 30 den Kopplungskörper 34 gegen einen zweiten Sicherungsring 38, der vom Hubmagneten 12 abgewandt ist, am Stößel 16 drückt. Hierbei dient der Sicherungsring 38 als Anschlag für den Kopplungskörper 34. Mittels der zweiten Druckfeder 32, die zwischen dem Kopplungskörper 34 und dem Verriegelungsstift 18 angeordnet ist, wird der Verriegelungsstift 18 nach oben bzw. in Richtung des bistabilen Hubmagneten 12 gedrückt. Die erste Druckfeder 30 und die zweite Druckfeder 32 sind jeweils vorgespannt.For the inner compression spring 30, an upper, end-side locking ring 36, which faces the solenoid 12, is designed on the plunger 16 as a stop for the inner spring 30, so that the inner compression spring 30 holds the coupling body 34 against a second locking ring 38, which is from the solenoid 12 is facing away, presses on the plunger 16. Here, the locking ring 38 serves as a stop for the coupling body 34. By means of the second compression spring 32, which is arranged between the coupling body 34 and the locking pin 18, the locking pin 18 is pressed upwards or in the direction of the bistable lifting magnet 12. The first compression spring 30 and the second compression spring 32 are each pretensioned.

Die erste Druckfeder 30 und die zweite Druckfeder 32 sind koaxial in Bezug auf die Längsachse des Stößel 16 bzw. die Bewegungsachse des Stößels 16 angeordnet, wobei die Druckfedern 30, 32 ineinander angeordnet sind. Die erste Druckfeder 30 und die zweite Druckfeder 32 bilden eine Spanneinrichtung zwischen dem linearbewegbaren Stößel 16 und dem linear bewegbaren Verriegelungsstift 18 aus, so dass aufgrund der Vorspannung der Druckfedern 30, 32 der Stößel 16 mit dem Verriegelungsstift 18 verbunden bzw. gekoppelt ist.The first compression spring 30 and the second compression spring 32 are arranged coaxially with respect to the longitudinal axis of the plunger 16 and the axis of movement of the plunger 16, respectively, the compression springs 30, 32 being arranged one inside the other. The first compression spring 30 and the second compression spring 32 form a tensioning device between the linearly movable plunger 16 and the linearly movable locking pin 18, so that due to the preload of the compression springs 30, 32, the plunger 16 is connected or coupled to the locking pin 18.

Im Normalbetrieb wird der drehbare Türhaken 26 in die Türhakenaufnahme 28 des Drehsegments 24 eingebracht (vgl. Fig. 1), wobei anschließend das Drehsegment 24 in eine Verriegelungsposition im Uhrzeigersinn gedreht wird, bis die Verriegelungsnut 22 des Drehsegments 24 unterhalb des Verriegelungszapfens 20 des Verriegelungsstifts 18 angeordnet ist (vgl. Fig. 2). Anschließend wird der Anker 14 zusammen mit dem Stößel 16 aus einer Endlage (obere Position in Fig. 2) in die zweite Endlage (untere Position) bewegt, wodurch der Verriegelungszapfen 20 in Richtung der Verriegelungsnut 22 bewegt wird und eingreift. Dadurch ist das Drehsegment 24 zusammen mit dem Türhaken 26 gesperrt.During normal operation, the rotatable door hook 26 is inserted into the door hook receptacle 28 of the rotating segment 24 (cf. Fig. 1 ), whereby the rotary segment 24 is then rotated into a locking position clockwise until the locking groove 22 of the rotary segment 24 is arranged below the locking pin 20 of the locking pin 18 (cf. Fig. 2 ). The anchor 14 is then moved together with the plunger 16 from an end position (upper position in Fig. 2 ) moves into the second end position (lower position), whereby the locking pin 20 is moved in the direction of the locking groove 22 and engages. As a result, the rotating segment 24 is locked together with the door hook 26.

Im Fall, dass das Drehsegment 24 nicht in der Verriegelungsposition für den Verriegelungsvorgang, wie in Fig. 1 dargestellt, positioniert ist, kann der Verriegelungsstift 18 in eine Wartestellung für die Verriegelung gebracht werden, indem der Hubmagnet 12 bestromt wird, wodurch der Stößel 16 (nach unten) bewegt wird, so dass die erste Druckfeder 30 weiter bzw. noch mehr vorgespannt wird. In dieser Position drückt der Verriegelungsstift 18 gegen das Drehsegment 24. Um das Drehsegment 24 zu verriegeln, wird dieses im Uhrzeigersinn gedreht, so dass der Verriegelungszapfen 20 des Verriegelungsstifts 18 aufgrund der vorgespannten ersten (inneren) Druckfeder 32 in die Verriegelungsnut 22 des Drehsegments 24 gebracht wird.In the event that the rotating segment 24 is not in the locking position for the locking process, as in Fig. 1 is shown, the locking pin 18 can be brought into a waiting position for the locking by energizing the solenoid 12, whereby the plunger 16 is moved (downwards), so that the first compression spring 30 is preloaded further or even more. In this position, the locking pin 18 presses against the rotating segment 24. In order to lock the rotating segment 24, it is rotated clockwise so that the locking pin 20 of the locking pin 18 is brought into the locking groove 22 of the rotating segment 24 due to the prestressed first (inner) compression spring 32 becomes.

Bei Entriegelung bzw. Verriegelung des Drehsegments 24 werden beim Öffnen bzw. beim Schließen der Verriegelungsvorrichtung 10 bei Bestromung des bistabilen Hubmagneten 12 der Stößel 16 und der Verriegelungsstift 18 in Richtung bzw. entgegen der Richtung des Hubmagneten bewegt, wodurch aufgrund der am Stößel 16 gleichzeitig eingreifenden Druckfedern 30, 32 der Verriegelungsstift 18 entsprechend bewegt wird.When unlocking or locking the rotary segment 24, when opening or closing the locking device 10 when the bistable lifting magnet 12 is energized, the plunger 16 and the locking pin 18 are moved in the direction or against the direction of the lifting magnet, whereby due to the on the plunger 16 at the same time engaging compression springs 30, 32 of the locking pin 18 is moved accordingly.

Im Fall, dass in einer Verriegelungsposition, in der der Verriegelungszapfen 20 des Verriegelungsstifts 18 in die Verriegelungsnut 22 des Drehsegments 24 eingreift und das Drehsegment 24 mit einer äußeren, manuellen Kraft gegen den eingreifenden Verriegelungszapfen 20 gedreht wird, so dass der Verriegelungsstift 18 an einer freien linearen Bewegung gehindert wird, ist es möglich, dass durch die Bestromung des Hubmagneten 12 der Stößel 16 in Richtung des Hubmagneten 14 bewegt wird, wodurch die zweite äußere Druckfeder 32 (noch mehr) vorgespannt wird, wobei der Verriegelungsstift 18 in der Verriegelungsposition gehalten ist oder wird. Wird anschließend die Verriegelung des Verriegelungsstifts 18 gelöst, wird der blockierte Verriegelungsstift 18 durch die vorgespannten Druckfeder 32 in die entriegelte Position linear bewegt.In the event that in a locking position in which the locking pin 20 of the locking pin 18 engages in the locking groove 22 of the rotating segment 24 and the rotating segment 24 is rotated with an external, manual force against the engaging locking pin 20, so that the locking pin 18 is at a free position linear movement is prevented, it is possible that the plunger 16 is moved in the direction of the lifting magnet 14 by energizing the lifting magnet 12, whereby the second outer compression spring 32 is prestressed (even more), with the locking pin 18 being held in the locking position or becomes. If the locking of the locking pin 18 is then released, the blocked locking pin 18 is moved linearly into the unlocked position by the prestressed compression spring 32.
