Description

Die Erfindung betrifft eine Türverriegelung der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a door lock of the type mentioned in the preamble of claim 1.

Eine Türverriegelung der betreffenden Art ist beispielsweise aus dem Bestellkatalog "Elektromechanik Schalt-, Schutz- und Steuergeräte 2000", Seiten 253 und 254, der Firma E-T-A Elektrotechnische Apparate GmbH, 90518 Altdorf bekannt. Das dort beschriebene Verriegelungssystem mit der Nummer 6140 weist einen in einer Schließstellung in eine Aufnahme einer Tür eingreifenden Haken als Schließkloben auf, wobei das Verriegelungssystem in dem eingebauten Zustand beispielsweise an einem Korpus und die Aufnahme als Schlossfalle an der Tür eines Haushaltgeräts angeordnet ist. Der Haken ist drehbar an dem Rest des Verriegelungssystems gehaltert und befindet sich bei geöffneter Tür in einer Öffnungsstellung. Ferner ist an dem Haken ein Vorsprung als Anschlag ausgebildet. Bei dem Schließen der Tür drückt diese gegen den Vorsprung, wodurch der Haken von der Öffnungsstellung in die Schließstellung überführt wird. Ein Nachteil der bekannten Türverriegelung ist, dass deren Funktionieren aufgrund von Toleranzen der relativen Lage von Verriegelungssystem und Aufnahme beeinträchtigt oder unmöglich ist. Toleranzen können beispielsweise durch fertigungs- bzw. montagebedingte Abweichungen in den Abmessungen von Tür und/oder Korpus des Haushaltgeräts bzw. von Verriegelungssystem und Aufnahme hervorgerufen werden. Größere Toleranzen können darüber hinaus zu Beschädigungen an der Türverriegelung bis zu deren vollständigen Unbrauchbarkeit führen.A door lock of the type in question is, for example, from the order catalog "Electromechanical switching, protection and control devices 2000", pages 253 and 254, from the company E-T-A Elektrotechnische Apparate GmbH, 90518 Altdorf. The one described there Locking system with the number 6140 points one in a closed position Inclusion of a door engaging hook as a locking block, the Locking system in the installed state, for example on a body and the Recording is arranged as a lock latch on the door of a household appliance. The catch is rotatably supported on the rest of the locking system and is with the door open in an open position. Furthermore, a projection is formed as a stop on the hook. When the door closes, it presses against the protrusion, causing the hook of the Open position is transferred to the closed position. A disadvantage of the known Door lock is that its functioning due to tolerances of the relative location of Locking system and recording is impaired or impossible. Tolerances can for example due to manufacturing or assembly-related deviations in dimensions of the door and / or body of the household appliance or of the locking system and holder are caused. Larger tolerances can also damage the Lock the door until it is completely unusable.

Der Erfindung stellt sich somit das Problem eine Türverriegelung zu schaffen, deren Funktion auch bei unüblich großen Toleranzen der Abmessungen und/oder der räumlichen Anordnung der verwendeten Bauteile gewährleistet ist.The invention thus presents the problem of creating a door lock, its function even with unusually large tolerances of the dimensions and / or the spatial arrangement the components used is guaranteed.

Erfindungsgemäß wird dieses Problem durch eine Türverriegelung mit den Merkmalen des Patentanspruchs 1 oder 2 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by a door lock with the features of Claim 1 or 2 solved. Advantageous refinements and developments of Invention emerge from the following subclaims.

Eine Türverriegelung mit einem Toleranzausgleich ist aus der DE 197 38 508 C1 bereits bekannt. Bei dem Gegenstand dieser Schrift ist zum Verriegeln einer Ofenmuffeltür an dieser ein Verriegelungsbolzen als Schließkloben vorgesehen, der in eine mittels einer Trägereinrichtung an dem Korpus des Ofens befestigten Aufnahmeeinrichtung als Schlossfalle einführbar ist. In Abhängigkeit von einem Steuersignal ist der Verriegelungsbolzen von der Aufnahmeeinrichtung gesperrt oder freigegeben. Um Toleranzen der relativen Position von Verriegelungsbolzen und Aufnahmeeinrichtung ausgleichen zu können, ist die Aufnahmeeinrichtung auf der Trägereinrichtung beweglich angeordnet. Nachteilig bei dieser Lösung ist, dass die bewegte Masse groß ist, da die gesamte Aufnahmeeinrichtung relativ zur Trägereinrichtung bewegt wird. Aufgrund dessen ist es bei dem bekannten Toleranzausgleich erforderlich, die Bauteile der Türverriegelung, wie beispielsweise das Federelement zur Kompensierung der auf die Aufnahmeeinrichtung einwirkenden Kräfte, mit Rücksicht auf die bei der Bewegung der großen Masse auftretenden Kräfte auszulegen, was Bauteile mit großen Abmessungen und/oder den Einsatz qualitativ hochwertiger Materialien erfordert. Darüber hinaus bedingt dieser Toleranzausgleich, bei dem die gesamte Aufnahmeeinrichtung beweglich ist, einen größeren Platzbedarf für die Türverriegelung.A door lock with tolerance compensation is already from DE 197 38 508 C1 known. The subject of this document is to lock a muffle door on this a locking bolt is provided as a locking block, which in a means of a Carrier device attached to the body of the furnace as a lock latch can be introduced. Depending on a control signal, the locking bolt is from the Recording facility blocked or released. To tolerances of the relative position of To be able to compensate the locking bolt and the receiving device is Receiving device movably arranged on the carrier device. A disadvantage of this The solution is that the moving mass is large because the entire receiving device is relative to the Carrier device is moved. Because of this, it is with the known tolerance compensation required, the components of the door lock, such as the spring element for Compensation of the forces acting on the receiving device, taking into account the to interpret the movement of large mass forces, which are components with large Dimensions and / or the use of high quality materials required. About that In addition, this tolerance compensation, in which the entire receiving device is movable is a larger space requirement for the door lock.

Die mit der Erfindung erreichbaren Vorteile bestehen neben dem Funktionieren der Türverriegelung auch bei unüblich großen Toleranzen der Abmessungen und/oder der räumlichen Anordnung der verwendeten Bauteile in einer raumsparenden Ausgestaltung des Toleranzausgleichs, da es nicht erforderlich ist, die Schlossfalle bzw. den Schließkloben als Ganzes zu bewegen. Somit kann der eingesparte Raum für andere Bauteile verwendet werden bzw. ist ein kompakteres Haushaltgerät ermöglicht. Ferner ist es nicht erforderlich, besonders hochwertige Materialien für die Bauteile des Toleranzausgleichs zu verwenden, da die bewegten Massen und die damit einhergehenden Kräfte geringer sind, so dass die Türverriegelung in deren Gesamtheit und der Toleranzausgleich im Besonderen einfach und kostengünstig herstellbar ist. Hierbei ist es unerheblich, ob der Anschlag selbst oder dessen Lagerung federnd ausgebildet ist, da beides Ausgestaltungen derselben technischen Lösung sind.The advantages that can be achieved with the invention exist in addition to the functioning of the Door locking even with unusually large tolerances in dimensions and / or spatial arrangement of the components used in a space-saving design of the Tolerance compensation, since it is not necessary to use the lock latch or the locking block as To move the whole. The space saved can thus be used for other components or a more compact household appliance is possible. Furthermore, it is not necessary, especially to use high-quality materials for the components of the tolerance compensation, since the moving masses and the associated forces are lower, so that the Door locking in its entirety and tolerance compensation in particular simple and is inexpensive to manufacture. It is irrelevant whether the attack itself or its Storage is resilient, since both embodiments of the same technical solution are.

Grundsätzlich ist es möglich, die Türverriegelung für eine Aufreißtür geeignet auszubilden. Eine vorteilhafte Weiterbildung der erfindungsgemäßen Lehre sieht jedoch vor, dass der Schließkloben durch ein zweites krafterzeugendes Mittel in der Schließstellung sicherbar ist. Auf diese Weise ist eine sichere Verriegelung der Tür gewährleistet, die insbesondere für Häushaltgeräte mit einem hohen Gefahrenpotential, wie beispielsweise Herde oder Backöfen mit pyrolytischer Selbstreinigung, erforderlich ist.Basically, it is possible to design the door lock to be suitable for a pull-open door. A advantageous development of the teaching according to the invention, however, provides that the Locking block can be secured in the closed position by a second force-generating means. In this way, a secure locking of the door is ensured, which is especially for Household appliances with a high risk potential, such as stoves or ovens with pyrolytic self-cleaning is required.

Eine vorteilhafte Weiterbildung der vorgenannten Ausführungsform ist, dass das zweite krafterzeugende Mittel ein in eine Ausnehmung des Schließklobens eingreifbarer Bolzen ist. Hierdurch ist das zweite krafterzeugende Mittel besonders einfach und kostengünstig verwirklicht.An advantageous development of the aforementioned embodiment is that the second force-generating means is a pin which can be engaged in a recess in the locking block. As a result, the second force-generating agent is particularly simple and inexpensive realized.

Eine weitere vorteilhafte Weiterbildung der erfindungsgemäßen Lehre sieht vor, dass das erste krafterzeugende Mittel eine Feder ist, die mit ihrem einen freien Ende an dem Schließkloben und mit ihrem anderen freien Ende an einem Rest des Haushaltgeräts gehaltert ist. Auf diese Weise ist das erste krafterzeugende Mittel einfach und kostengünstig herstellbar, da Federn Standardbauteile sind. Another advantageous development of the teaching according to the invention provides that the first force-generating means is a spring, which has one free end on the locking block and is attached to a rest of the household appliance with its other free end. To this The first force-generating agent is easy and inexpensive to produce, because springs Standard components are.

Grundsätzlich ist Art, Material und Größe der Feder als erstes krafterzeugendes Mittel in weiten Grenzen wählbar. Zweckmäßigerweise ist die Feder eine Schraubenfeder.Basically, the type, material and size of the spring is the first force-generating agent in a wide range Limits selectable. The spring is expediently a helical spring.

Eine andere vorteilhafte Weiterbildung der erfindungsgemäßen Lehre sieht vor, dass der Anschlag eine Schenkelfeder ist. Hierdurch ist die Türverriegelung auf besonders einfache Weise mit einem Toleranzausgleich ausbildbar.Another advantageous development of the teaching according to the invention provides that the Stop is a leg spring. As a result, the door lock is particularly simple Formable with tolerance compensation.

The coil spring 16 is biased to train, so that this promotes the rotation of the hook 8 clockwise. The rotation of the hook 8 in Clockwise is limited by a pin 18 as a stop for the hook 8. Furthermore is on a recess 20 is provided in the same arm, in which a merely schematic shown bolt 22 can be engaged. The pin 22 is also schematic along one shown guide 24 between an unlocked position and a locked position movable back and forth, the bolt 22 in the locking position in the recess 20th engages and thus sets the hook 8 in a closed position. The bolt 22 and the Guide 24 therefore cooperate as a second force-generating means.

Nachfolgend ist die Funktionsweise der erfindungsgemäßen Türverriegelung 2 anhand des in den Fig. 1 bis 5 dargestellten ersten Ausführungsbeispiels erläutert:The mode of operation of the door lock 2 according to the invention is described below with reference to FIG 1 to 5 illustrated first embodiment:

Wie bereits oben ausgeführt, zeigt die Fig. 1 die erfindungsgemäße Türverriegelung 2 in einer Öffnungsstellung des Hakens 8, in der die Tür 4 die Backmuffel des Herdes nicht verschließt. Der Haken 8 liegt, gefördert durch die Rückstellkraft der Schraubenfeder 16, mit dem der Tür 4 abgewandten Arm an dem Zapfen 18 an. Die Schenkelfeder 14 ist entspannt und der Haken 8 ist mit der Aufnahme 6 der Tür 4 nicht in Eingriff. Der Bolzen 22 befindet sich in der Entriegelungsstellung.As already explained above, FIG. 1 shows the door lock 2 according to the invention in one Open position of the hook 8, in which the door 4 does not close the muffle of the cooker. The hook 8 lies, promoted by the restoring force of the coil spring 16, with that of the door 4 facing arm on the pin 18. The leg spring 14 is relaxed and the hook 8 is not in engagement with the receptacle 6 of the door 4. The bolt 22 is in the Unlocked.

In dem in Fig. 2 festgehaltenen Moment bei dem Schließen der Tür 4 befindet sich der Haken 8 noch nicht in Eingriff mit der Aufnahme 6 der Tür 4, die den als Anschlag ausgebildeten Schenkel der Schenkelfeder 14 gerade berührt. Wird die Tür 4 weiter in Richtung auf den Korpus des Herdes hin bewegt, so wird der Haken 8 gegen den Uhrzeigersinn um den Zapfen 12 gedreht. Dabei wird die Schraubenfeder 16 weiter auf Zug gespannt und der Haken 8 liegt mit dem der Tür 4 abgewandten Arm nicht länger an dem Zapfen 18 an. Die Schenkelfeder 14 ist weitgehend entspannt.The hook 8 is located at the moment when the door 4 is closed in FIG. 2 not yet in engagement with the receptacle 6 of the door 4, which is designed as a stop Leg of the leg spring 14 just touched. Will the door 4 continue towards the Body of the cooker moves, so the hook 8 is counterclockwise around the peg 12 rotated. The coil spring 16 is further tensioned and the hook 8 lies with the arm facing away from the door 4 no longer on the pin 18. The leg spring 14 is largely relaxed.

Am Ende des Schließvorgangs liegt die Tür 4 an dem Korpus des Herdes an, siehe Fig. 3. Der Haken 8 greift mit dem Vorsprung in die Aufnahme 6 der Tür 4 ein. In dieser Schließstellung wirkt die Druckkraft der Tür 4 gegen die Schenkelfeder 14 der Rückstellkraft der Schraubenfeder 16 entgegen, so dass der Haken 8 der Türverriegelung 2 in der Schließstellung verbleibt. Die Druckkraft der Tür 4 kann beispielsweise auf eine weitere von Korpus und Tür 4 gehalterten und zwischen diesen wirkenden Feder erzeugt werden. Wie aus Fig. 3 ersichtlich, liegen sich die Ausnehmung 20 und der in seiner Entriegelungsstellung dargestellte Bolzen 22 gegenüber, so dass der Bolzen 22 längs der Führung 24 in seine Verriegelungsstellung, in der der Bolzen 22 in die Ausnehmung 20 eingreift, bewegbar ist. At the end of the closing process, the door 4 lies against the body of the cooker, see Fig. 3. The Hook 8 engages with the projection in the receptacle 6 of the door 4. In this closed position acts the pressure force of the door 4 against the leg spring 14 of the restoring force Coil spring 16 counter so that the hook 8 of the door lock 2 in the The closed position remains. The compressive force of the door 4 can, for example, on another Body and door 4 held and generated between these acting spring. How out Fig. 3 can be seen, the recess 20 and the are in its unlocked position Bolt 22 shown opposite, so that the bolt 22 along the guide 24 in his Locking position in which the bolt 22 engages in the recess 20 is movable.

Befindet sich der Bolzen 22 in der nicht dargestellten Verriegelungsstellung, sind Korpus und Tür 4 mittels der Türverriegelung 2 miteinander verriegelt. Ein Öffnen der Tür 4 und damit der Backmuffel ist in der Verriegelungsstellung nicht möglich.Is the bolt 22 in the locking position, not shown, body and Door 4 locked together by means of door lock 2. Opening the door 4 and thus the Baking muffle is not possible in the locked position.

Fig. 4 zeigt die Anordnung aus Fig. 3 in der Draufsicht.Fig. 4 shows the arrangement of Fig. 3 in plan view.

Für den Fall, dass unübliche Abweichungen in den Abmessungen der Bauteile der Türverriegelung 2 bzw. der Tür 4 und/oder des Korpus oder deren relativer Lage zueinander dazu führen, dass sich die Tür 4 bei dem Schließen um das Gelenk 10 weiter in Richtung Korpus drehen lässt, als es der oben beschriebene Normalfall vorsieht, wird die Schenkelfeder 14 gespannt, wodurch der Überhub der Tür 4 kompensiert ist. Der aufgrund von fertigungsund/oder montagebedingten Toleranzen der Bauteilabmessungen bzw. der relativen Lage der einzelnen Bauteile der Türverriegelung 2 zueinander verursachte Überhub der Tür 4 führt demnach nicht zu einer Beschädigung bzw. Zerstörung des Anschlags oder anderer Bauteile der Türverriegelung 2, da die durch die Tür 4 bei dem Überhub in die Türverriegelung 2 eingeleitete Energie in Spannungsenergie der Schenkelfeder 14 umgewandelt wird. Ferner ist die Funktion der Türverriegelung 2 trotz Überhubs der Tür 4 gewährleistet.In the event that unusual deviations in the dimensions of the components of the Door lock 2 or the door 4 and / or the body or their relative position to each other cause the door 4 to continue to move when closing around the hinge 10 The torsion spring turns the body when the normal case described above provides 14 excited, whereby the overstroke of the door 4 is compensated. The due to manufacturing and / or assembly-related tolerances of the component dimensions or the relative position of the individual components of the door lock 2 leads to an overstroke of the door 4 therefore not to damage or destroy the stop or other components the door lock 2, because the door 4 during the overstroke into the door lock 2 initiated energy is converted into tension energy of the leg spring 14. Furthermore is the function of the door lock 2 is guaranteed despite the door 4 being overturned.

In den Fig. 6 und 7 ist ein zweites Ausführungsbeispiel einer erfindungsgemäßen Türverriegelung bei geschlossener Tür 4 gezeigt. Bei diesem Ausführungsbeispiel ist als Anschlag ein auf einer am Haken 8 ausgebildeten und sich längs des Hakens 8 erstreckenden Führung 25 gleitender Schlitten 26 verwendet. Die Bewegung des Schlittens 26 in Richtung der Tür 4 ist im Bereich des der Tür 4 zugewandten Endes der Führung 25 durch einen an dem Haken 8 ausgebildeten weiteren Vorsprung begrenzt. Eine auf Druck vorgespannte Lagerfeder 28 ist mit deren einem freien Ende an dem Schlitten 26 und mit deren anderem freien Ende an einem an dem Haken 8 ausgebildeten Absatz gehaltert. Analog zu dem bereits zu dem ersten Ausführungsbeispiel beschriebenen Normalfall wird der Schlitten 26 durch die Rückstellkraft der Lagerfeder 28 gegen den am Haken 8 ausgebildeten weiteren Vorsprung gedrückt. Im Falle des Überhubs der Tür 4 wird dieser, analog zu dem ersten Ausführungsbeispiel, durch den sich längs der Führung 25 und gegen die Rückstellkraft der Lagerfeder 28 von der Tür 4 weg bewegenden Schlitten 26 kompensiert.6 and 7 is a second embodiment of an inventive Door lock shown with door 4 closed. In this embodiment, as Stop on a trained on the hook 8 and extending along the hook 8 Guide 25 sliding carriage 26 used. The movement of the carriage 26 in the direction of Door 4 is in the region of the end of the guide 25 facing the door 4 by one on the Hook 8 formed further projection limited. A bearing spring preloaded under pressure 28 is at one free end of the carriage 26 and at the other free end a shoulder formed on the hook 8. Analogous to the first one Normal case described embodiment, the carriage 26 by the restoring force Bearing spring 28 pressed against the further projection formed on the hook 8. In the event of of the overturning of the door 4, this becomes analogous to the first exemplary embodiment along the guide 25 and against the restoring force of the bearing spring 28 away from the door 4 moving carriage 26 compensated.

Ein drittes Ausführungsbeispiel ist in Fig. 8 dargestellt. Bei diesem Ausführungsbeispiel ist als Anschlag ein um einen am Haken 8 ausgebildeten Zapfen 29 drehbarer Hebel 30 verwendet. Der Hebel 30 weist einen längeren Arm als Anschlag für die Tür 4 und einen kürzeren Arm auf. Eine Lagerfeder 28 ist ähnlich wie bei dem vorangegangenen Ausführungsbeispiel mit deren einem freien Ende an dem längeren Arm des Hebels 30 und mit deren anderem freien Ende an einem an dem Haken 8 ausgebildeten Absatz gehaltert. Die Bewegung des längeren Arms des Hebels 30 ist in Richtung der Tür 4 durch einen am Haken 8 ausgebildeten weiteren Vorsprung begrenzt, der das Gegenlager für den kürzeren Arm des Hebels 30 bildet. In dem bereits für vorhergehende Ausführungsbeispiele beschriebenen Normalfall wird der kürzere Arm des Hebels 30 durch die Rückstellkraft der Lagerfeder 28 gegen den am Haken 8 ausgebildeten weiteren Vorsprung gedrückt. Im Falle des Überhubs der Tür 4 wird dieser, analog zu den vorhergehenden Ausführungsbeispielen, durch den sich um den Zapfen 29 gegen den Uhrzeigersinn und gegen die Rückstellkraft der Lagerfeder 28 von der Tür 4 weg drehenden längeren Arm des Hebels 30 kompensiert.A third embodiment is shown in FIG. 8. In this embodiment, as Stop used a lever 30 rotatable about a pin 29 formed on the hook 8. The lever 30 has a longer arm as a stop for the door 4 and a shorter arm. A bearing spring 28 is similar to the previous embodiment with the same a free end on the longer arm of the lever 30 and the other free end a shoulder formed on the hook 8. The movement of the longer arm of the Lever 30 is in the direction of the door 4 by a further projection formed on the hook 8 limited, which forms the counter bearing for the shorter arm of the lever 30. In the already for previous exemplary embodiments described normal case is the shorter arm of the Lever 30 by the restoring force of the bearing spring 28 against that formed on the hook 8 further lead pressed. In the event of door 4 being overturned, this becomes analogous to that previous embodiments, through which the pin 29 against the Turn clockwise and against the restoring force of the bearing spring 28 away from the door 4 longer arm of the lever 30 compensated.

In Fig. 9 ist ein viertes Ausführungsbeispiel der erfindungsgemäßen Türverriegelung 2 dargestellt. Bei diesem Ausführungsbeispiel ist als Anschlag ein erster Schenkel eines federnden Metallstreifens 32 bei der Herstellung des Hakens 8 mit Kunststoff teilweise umspritzt bzw. angespritzt und dabei mit dem Haken 8 unlösbar verbunden. Beispielsweise ist der Haken 8 als Kunststoff-Spritzgussteil ausgebildet, während dessen Herstellung der Metallstreifen 32 in die Spritzgussform eingelegt worden ist. Der sich im wesentlichen senkrecht zu der Längsausdehnung des Hakens 8 erstreckende zweite Schenkel ist als Anschlag für die Tür 4 ausgebildet. In dem bereits mehrfach beschriebenen Normalfall liegt die Tür 4 an dem zweiten Schenkel des Metallstreifens 32 an, wobei der zweite Schenkel des Metallstreifens 32 im wesentlichen entspannt ist. Im Falle des Überhubs der Tür 4 wird der zweite Schenkel des Metallstreifens 32, analog zu den vorhergehenden Ausführungsbeispielen, gespannt und der Überhub kompensiert.9 shows a fourth exemplary embodiment of the door lock 2 according to the invention shown. In this embodiment, a first leg is a stop resilient metal strip 32 partially in the manufacture of the hook 8 with plastic overmoulded or injection molded and in this way permanently connected to the hook 8. For example the hook 8 is formed as a plastic injection molding, during its manufacture Metal strip 32 has been inserted into the injection mold. Which is essentially vertical to the longitudinal extent of the hook 8 extending second leg is a stop for the Door 4 trained. In the normal case already described several times, the door 4 is on the second leg of the metal strip 32, the second leg of the metal strip 32 is essentially relaxed. In the event of the door 4 lifting, the second leg of the Metal strip 32, analogous to the previous embodiments, stretched and the Overstroke compensated.
