Abstract

The mechanism to lock the door of a domestic appliance, and especially a cooking oven, has a ratchet (14) which is pressed by a spring force against a corresponding catch (80) to lock them together. The ratchet is at the appliance housing and the catch is at the appliance door, or vice versa. A slide (28), which can be moved between the ratchet and the catch, releases the ratchet in one position, lifts it clear in a second position and, in a third setting, is kept out of action.

Description

Die Erfindung betrifft eine Verriegelungseinrichtung für die Tür eines Haushaltsgerätes, insbesondere Haushaltsgargerätes.The invention relates to a locking device for the door of a household appliance, in particular Haushaltsgargerätes.

Es ist bekannt, Backofentüren zu verriegeln, um beispielsweise Kindern aus Sicherheitsgründen den Zugang zum Backofen zu verwehren. Hierzu sind der Tür und dem Backofen je ein Rastelement zugeordnet, die bei geschlossener Tür unter dem Einfluß einer Federkraft in Eingriff stehen und zum Öffnen der Tür mittels eines Betätigungselementes außer Eingriff bringbar sind.It is known to lock oven doors, for example, children to deny access to the oven for safety reasons. For this purpose, the door and the oven are each assigned a latching element, which are in the closed door under the influence of a spring force engaged and for opening the door by means of an actuating element can be disengaged.

Die DT 24 44 546 A1 offenbart einen Verriegelungsmechanismus für eine Backofentür, bei der eine durch Handbetätigung verformbare Platte im entspannten Zustand hinter einen Türvorsprung greift und bei quer zur Rückzugsrichtung wirkender Kraft durchbiegbar und damit vom Türvorsprung zurückziehbar ist. Diese Verriegelungsmechanismen sind zwar sehr einfach, müssen jedoch bei jeder Türöffnung betätigt werden, auch dann, wenn keine Kinder im Haushalt sind.The DT 24 44 546 A1 discloses a locking mechanism for a oven door in which a deformable by manual operation plate engages behind a door projection in the relaxed state and in transversely to the withdrawal direction force is deflectable and thus withdrawn from the door projection. Although these locking mechanisms are very simple, they must be operated at every door opening, even when there are no children in the household.

Diesem Nachteil sucht man bei einer aufwendigen Verriegelungseinrichtung nach DE 39 35 597 C2 durch eine Handhabe zu begegnen, die bei Bewegung in einer ersten Richtung Türöffnung ermöglicht und bei Bewegung in einer zweiten Richtung die Verriegelung außer Kraft setzt. Hierzu greift die Handhabe in einen Türbereich hinein, um bei vertikaler Bewegung ein in der Tür geführtes Rastelement entgegen einer Federkraft aus einer am Rahmen angeordneten Ausnehmung zurückzuziehen und bei horizontaler Bewegung das Rastelement über Kurvensteuerung in eine die Verriegelung außer Kraft setzende Einschnürstellung zu bringen.This disadvantage is sought after in a complex locking device DE 39 35 597 C2 by a handle too encounter, which allows movement in a first direction door opening and when moving in a second direction, the lock is disabled. For this purpose, the handle engages in a door area in order to retract a guided in the door latching element against a spring force from a recess disposed on the frame during vertical movement and to bring the latching element via cam control in a locking the setting out of force setting neck position in horizontal movement.

In der EP 0 795 722 A1 ist eine Sicherheitsvorrichtung zum Öffnen einer Backofentür beschrieben, die einen Anschlag aufweist, der mit einem am Backofen schwenkbeweglichen Handhebel derart zusammenwirkt, dass er in einer unbetätigten Position des Hebels an diesem türverriegelnd anliegt und in einer betätigten Position des Hebels ein Öffnen der Tür ermöglicht.In the EP 0 795 722 A1 a safety device for opening a oven door is described, which has a stop which cooperates with a hand lever pivotally mounted on the oven such that it bears in an unactuated position of the lever at the door latching and allows in an actuated position of the lever to open the door.

Der Erfindung liegt die Aufgabe zugrunde, eine einfache und sichere Verriegelungsvorrichtung zu schaffen.The invention has for its object to provide a simple and secure locking device.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruches 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.According to the invention, this object is solved by the features of claim 1. Advantageous developments emerge from the subclaims.

Der vorzugsweise handverschiebbare Schieber ist insbesondere zwischen Tür und Gehäuse hindurchführbar und in der dritten Position rastbar. Hierzu ist er in Schieberichtung unter Bildung eines Zwischenraumes, der einen das erste Rastelement freigebenden Abschnitt aufweisen kann, abschnittsweise in zwei Teile gespalten, die beim Rasten quer zur Verschieberichtung federnd nachgeben. Die Verschiebepositionen sind vorzugsweise von außen nach innen angeordnet.The preferably manually displaceable slide can be guided in particular between the door and the housing and can be latched in the third position. For this purpose, it is split in the sliding direction to form a gap, which may have a releasing the first latching portion, partially split into two parts that yield resiliently when resting transversely to the direction of displacement. The displacement positions are preferably arranged from the outside inwards.

Das erste Rastelement ist als Rasthebel ausgebildet, der mittels des Schiebers um eine parallel zur Verschiebeebene und senkrecht zur Verschieberichtung verlaufende Schwenkachse entgegen der Kraft einer Feder schwenkbar ist. Der Rasthebel lagert auf einem die Feder abstützenden und den Schieber führenden Träger. Der Schieber ist vorzugsweise lösbar am Träger aufgenommen, der seinerseits lösbar am Gehäuse angeordnet ist. Der Träger weist einen Anschlag auf, der die Bewegung des Rasthebels in Verriegelungsrichtung begrenzt.The first latching element is designed as a latching lever, which is pivotable by means of the slider about a parallel to the displacement plane and perpendicular to the direction of rotation pivot axis against the force of a spring. The detent lever rests on a support supporting the spring and the slider leading carrier. The slider is preferably detachably received on the carrier, which in turn is detachably mounted on the housing. The carrier has a stop which limits the movement of the locking lever in the locking direction.

Das zweite Rastelement ist als Vorsprung ausgebildet, der auf der dem ersten Rastelement gegenüberliegenden Seite der Verschiebeebene angeordnet und quer zu dieser gerichtet ist. Der Vorsprung ist vorzugsweise Teil einer den Rasthebel aufnehmenden Ausnehmung. Er ist an der Tür angeordnet.The second latching element is formed as a projection which is arranged on the opposite side of the first latching element of the displacement plane and directed transversely to this. The projection is preferably part of a recess receiving the detent lever. He is at the door.

Die Figuren 1 und 2 zeigen einen rechtwinkligen Träger 2 mit einem (hier horizontalen) Trägerschenkel 4 und einem (hier vertikalen) Trägerschenkel 6. Der Träger 2 ist vorzugsweise ein Formteil, beispielsweise aus Kunststoff.The Figures 1 and 2 show a rectangular support 2 with a (here horizontal) support leg 4 and a (here vertical) support leg 6. The support 2 is preferably a molding, for example made of plastic.

Der Trägerschenkel 4 besteht aus einem äußeren Abschnitt 8 und einem inneren Abschnitt 10, die unter Bildung eines Zwischenraumes 12 voneinander beabstandet sind.The carrier leg 4 consists of an outer portion 8 and an inner portion 10, which are spaced apart to form a gap 12.

Am äußeren Trägerschenkelabschnitt 8 ist eine Lagerung 12 ausgebildet, in der ein rechtwinkliger Rasthebel 14 mit Rasthebelschenkeln 16 und 18 um eine Schwenkachse 20 lagert, die parallel zur Berührungskante 22 der Trägerschenkel 4 und 6 und zur Berührungskante 24 der Rasthebelschenkel 16 und 18 verläuft. Der Zwischenraum ist als eine in Schwenkrichtung verlaufende Führung 26 zum Führen eines flachen Schiebers 28 ausgebildet oder für eine solche Führung vorgesehen. Die Innenseite des inneren Abschnittes 10 ist glatt. Durch beide Abschnitte 8, 10 des Trägerschenkels 4 führt eine dazu senkrechte Öffnung 30.At the outer carrier leg portion 8, a bearing 12 is formed, in which a rectangular locking lever 14 with locking lever legs 16 and 18 supports about a pivot axis 20 which extends parallel to the contact edge 22 of the support legs 4 and 6 and the contact edge 24 of the locking lever legs 16 and 18. The gap is formed as a pivoting guide 26 for guiding a flat slider 28 or provided for such a guide. The inside of the inner portion 10 is smooth. Through both sections 8, 10 of the support leg 4 leads to a perpendicular opening 30th

Die Schwenkbarkeit des vorzugsweise aus Kunststoff bestehenden Rasthebels 14 ist durch einen Lagerbolzen 32 gewährleistet, der durch den Rasthebelschenkel 16 und die Lagerung 12 führt und an einem Ende eine axial wirkende Abschlußscheibe 34 und am anderen Ende ein axial wirkendes Sicherungselement 36 trägt. Zwischen der Lagerung 12 und der Abschlußscheibe 34 ist auf dem Lagerbolzen 32 eine Drehfeder 40 aufgenommen, deren beide Enden 42 und 44 zunächst in entgegengesetzte radiale Richtungen und dann rechtwinklig dazu in eine achsparallele Bohrung 46 der Lagerung 12 und eine achsparallele Bohrung des Rasthebels 14 führen können, um sich dort jeweils abzustützen. Diese Abstützung ist jedoch auch gegeben, wenn das Ende 44 einfach am Rasthebel 14 aufliegt, beispielsweise auf einem daran ausgebildeten Anschlag 48.The pivoting of the preferably made of plastic latching lever 14 is ensured by a bearing pin 32 which passes through the locking lever leg 16 and the bearing 12 and at one end an axially acting washer 34 and at the other end carries an axially acting locking element 36. Between the bearing 12 and the closure plate 34 is a torsion spring 40 is received on the bearing pin 32, the two ends 42 and 44 may initially lead in opposite radial directions and then perpendicular thereto in an axially parallel bore 46 of the bearing 12 and an axially parallel bore of the locking lever 14 to support each one there. However, this support is also given when the end 44 simply rests on the locking lever 14, for example on a stop 48 formed thereon.

Der Rasthebelschenkel 18 erstreckt sich durch die Öffnung 30 des Trägerschenkels 4 hindurch. An seinem freien Ende befindet sich eine dem Schieber zugewandte Anlaufschräge 50.The locking lever leg 18 extends through the opening 30 of the support leg 4 therethrough. At its free end there is a slide 50 facing the slide.

Der äußere Trägerschenkelabschnitt 8 weist ein Verstärkungsprofil 52 auf, das senkrecht zur Berührungskante beider Trägerschenkel 4 und 6 verläuft.The outer carrier leg section 8 has a reinforcing profile 52 which runs perpendicular to the contact edge of both carrier legs 4 and 6.

Durch den Trägerschenkel 6 führt eine an den Querschnitt des Schiebers angepaßte Öffnung 54 (Fig. 4 bis 6) und eine Befestigungsbohrung 56. In einem Bereich ist der Trägerschenkel 6 unter Ausbildung eines Formelementes 58, welches mit einem weiteren Formelement 60 des Garofengehäuses haltend zusammenwirkt, verstärkt ausgebildet. Hier stellt sich das Formelement 58 als eine von der Berührungskante 22 des Trägers 2 wegweisende berührungskantenparallele Ausnehmung zur Aufnahme einer Gehäusekante dar.Through the support leg 6 performs an adapted to the cross section of the slider opening 54 ( 4 to 6 ) and a mounting hole 56. In one area, the support leg 6 is formed to form a shaped element 58, which cooperates with another mold element 60 of the Garofengehäuses holding reinforced. Here, the shaped element 58 presents itself as a contact edge-parallel recess facing away from the contact edge 22 of the carrier 2 for receiving a housing edge.

Fig. 3 zeigt den Schieber 28 in Raststellung. Er weist in Reihenfolge einen rechtwinklig abgebogenen (Fig. 1 und 2) bedienerseitigen Griffbereich G, einen in der Führung 26 geführten Führungsbereich F, einen weit geteilten Freigabebereich W zur Freigabe des Rasthebels 14 und einen schmal geteilten Federbereich S zur federnden Herstellung der Rastverbindung mit der Führung 26 auf. Der schmal geteilte Federbereich S ist bis auf zwei gegenüberliegende Rastspitzen RS, die in Rastausnehmungen RA der am Schieber 28 anliegenden Führung 26 sitzen, auch außen schmaler als der Freigabebereich W. Ein Teil des Federbereiches S reicht durch die Öffnung 54 des Trägerschenkels 6 hindurch. Fig. 3 shows the slider 28 in the locked position. He shows in a right angle bent ( Fig. 1 and 2 ) Operator-side grip area G, guided in the guide 26 guide area F, a widely shared release area W to release the locking lever 14 and a narrow split spring area S for resilient production of the locking connection with the guide 26. The narrow split spring area S is also narrower on the outside than the release area W except for two opposite latching points RS, which are seated in latching recesses RA of the slide 28 resting against the slide 28. A portion of the spring area S extends through the opening 54 of the carrier leg 6.

Die Figuren 4 bis 6 zeigen den Schnitt durch einen vorderen Randbereich eines verschlossenen Garofens mit einem Abschnitt eines Türrahmens 62 einer Garofentür, einem Abschnitt einer Türanlagefläche 64 des Garofens, einem Abschnitt eines als U-förmiger Umbug ausgebildeten Garofenrahmens 66 und einer oberhalb des Türrahmens 62 angeordneten Bedienblende 68, die den Garofenrahmen 66 nach vorn abdeckt.The FIGS. 4 to 6 show the section through a front edge region of a closed cooking oven with a portion of a door frame 62 of a Garofentür, a portion of a Türanlagefläche 64 of the Garofens, a portion of a U-shaped Umbug trained Garofenrahmens 66 and arranged above the door frame 62 control panel 68 which covers the Garofenrahmen 66 forward.

Im beschriebenen Abschnitt verläuft die Stirnseite des Türrahmens 62 parallel zur gegenüberliegenden Bedienblende 68 und zum gegenüberliegenden Umbug 66 des Garofenrahmens. In Richtung der Türanlagefläche 64 des Garofens weist der Türrahmen 62 eine stirnseitige Mulde 70 auf. In entgegengesetzter Richtung ist der stirnseitige Türrahmenabschnitt 62 vor die Bedienblende 68 geführt, um zwischen diesem Abschnitt und einem dazu parallelen Abschnitt ein Türgriffprofil 72 aufzunehmen, das mit der Stirnseite des Türrahmenabschnittes fluchtet.In the described section, the front side of the door frame 62 runs parallel to the opposite control panel 68 and to the opposite Umbug 66 of the Garofenrahmens. In the direction of the door contact surface 64 of the oven, the door frame 62 has a frontal depression 70. In the opposite direction of the frontal door frame portion 62 is guided in front of the control panel 68 to receive between this section and a parallel section a door handle profile 72 which is aligned with the front side of the door frame section.

Die an Hand der Figuren 1 bis 3 vorgestellte Rasthebelbaugruppe ist gemäß der Figuren 4 bis 6 zum einen auf den Umbug 66 aufgeschoben und zum anderen mit der Ausnehmung 58 auf eine Gehäusekante 60 aufgesetzt und mittels eines durch die Befestigungsbohrung 56 reichenden Gummistopfens 74 befestigt, so daß der Öffnung 30 bzw. dem durch diese Öffnung hindurchreichenden Rasthebelschenkel 18 die Mulde 70 des Türrahmens 62 gegenübersteht, die eine mit der Anlaufschräge 50 des Rasthebels 14 korrespondierende Schräge 76 aufweist, an die sich in Richtung Garofen ein türnormaler Abschnitt 78 und ein türparalleler Abschnitt 80 anschließt.The on hand of the FIGS. 1 to 3 presented Rasthebelbaugruppe is according to the FIGS. 4 to 6 pushed on the one Umbug 66 and placed on the other with the recess 58 on a housing edge 60 and fastened by means of a mounting hole 56 reaching rubber stopper 74, so that the opening 30 and passing through this opening Rasthebelschenkel 18, the trough 70 of the door frame 62 facing, which has a bevel 76 corresponding to the run-on slope 50 of the locking lever 14, to which in the direction Garofen a door normal section 78 and a door-parallel section 80 connects.

In der in Fig. 4 gezeigten Verriegelungsstellung der Garofentür fluchtet die Auslenkkante des Schiebers 28 mit der o-fenabgewandten Begrenzung der Öffnung 30, wodurch der Rasthebelschenkel 18 unter dem Einfluß der Kraft der Feder 40 voll in die Mulde 70 der Garofentür eintauchen kann, um ein Öffnen der Tür zu verhindern. Die Anlaufschräge 50 des Rasthebels liegt dabei an der Schräge 76 der Mulde 70 an.In the in Fig. 4 shown locking position of the Garofentür the deflection edge of the slider 28 is aligned with the o-fenabgewandten boundary of the opening 30, whereby the locking lever leg 18 under the influence of the force of the spring 40 can fully immerse in the trough 70 of the Garofentür to open to prevent the door. The run-on slope 50 of the locking lever is applied to the slope 76 of the trough 70.

Wünscht man die Tür zu öffnen, muß man den Schieber 28 in Richtung Garofen schieben, so daß die Auslenkkante den Rasthebel 14 entgegen der Kraft der Feder um die Achse 20 schwenkt und soweit aus der Mulde 70 herausbewegt, daß sich seine Unterkante über der senkrechten Kante 80 der Mulde 70 befindet (Fig. 5). Damit dies nur Erwachsenen oder größeren Kindern, beispielsweise Schulkindern, möglich ist, ist hierzu eine Kraft von 30 N vorgesehen. Die Tür ist jedoch auch dann nur solange zu öffnen, solange man den Schieber 28 in dieser Stellung hält. Andernfalls schiebt der Rasthebelschenkel 18 unter dem Einfluß der Kraft der Feder 40 den Schieber 28 wieder in die Ausgangslage gemäß Fig. 4 zurück. Dies geschieht auch nach dem erfolgreichen Öffnen der Tür. Beim erneuten Schließen greift dann die hintere Kante 80 der Mulde 70 an der Anlaufschräge 50 des Rasthebelschenkels 18 an und lenkt diesen bis zum Wiedereinrasten in der Mulde 70 aus. Ein erneutes Öffnen erfordert so wiederum ein Betätigen des Schiebers 28.If you want to open the door, you have to push the slider 28 in the direction of Garofen, so that the deflecting the locking lever 14 pivots against the force of the spring about the axis 20 and as far out of the trough 70 moves that its lower edge over the vertical edge 80 of the trough 70 is located ( Fig. 5 ). In order for this to be possible only for adults or older children, for example schoolchildren, a force of 30 N is provided for this purpose. However, the door is only then open as long as you hold the slider 28 in this position. Otherwise, the detent lever leg 18 pushes the slider 28 back to the starting position under the influence of the force of the spring 40 Fig. 4 back. This happens even after the door has been successfully opened. When re-closing then engages the rear edge 80 of the trough 70 on the run-on slope 50 of the locking lever leg 18 and deflects it until re-engagement in the trough 70 from. Reopening thus again requires actuation of the slide 28.

Da die Zeit, in der sich kleine Kinder, beispielsweise Kindergartenkinder im Haushalt befinden, begrenzt ist, stellt die erfindungsgemäße Verriegelungsvorrichtung auch eine dritte Verschiebeposition des Schiebers 28 zur Verfügung. Sie läßt sich einstellen, wenn man den Schieber bis in eine über die Öffnungsposition hinausreichende rastende Position bringt, in der ein Schließen der Tür nicht zum Wiedereinrasten des Rasthebels 14 führt (Fig. 6). Dies erfordert aus Sicherheitsgründen eine Kraft von etwa 60N. Beim Verschieben in die Raststellung gelangen die Rastspitzen RS des Schiebers 28 zunächst an die enger werdende Führung 26, so daß sich die gespaltenen Teile des Schiebers nach innen bewegen, bis die Spitzen RS nachfolgend in Ausnehmungen der Führung 26 zurückfedern können und den Schieber 28 verrasten.Since the time in which small children, such as kindergarten children are in the household is limited, the locking device according to the invention also provides a third shift position of the slider 28 is available. It can be adjusted if the slide is brought into a latching position extending beyond the opening position, in which closing the door does not lead to re-engagement of the latching lever 14 ( Fig. 6 ). For safety reasons, this requires a force of about 60N. When moving into the detent position reach the latching spikes RS of the slider 28 first to the narrowing guide 26 so that the split parts of the slider move inwards until the tips RS can subsequently spring back into recesses of the guide 26 and lock the slide 28.

Ist es erneut erforderlich, in den Verriegelungsmodus zurückzukehren, wird einfach der Schieber 28 aus der Rastposition zurückgezogen.Again, if it is necessary to return to the lock mode, the slider 28 is simply retracted from the detent position.

Mit diesen drei Verschiebepositionen läßt sich auf einfache Weise sowohl den Sicherheitsanforderungen als auch den Anforderungen an den Bedienkomfort gerecht werden. Die separate Ausbildung des Schiebers ermöglicht eine einfache Anpassung an unterschiedliche Designlösungen der Haushaltsgeräte.With these three displacement positions can be easily meet both the safety requirements and the requirements for ease of use. The separate design of the slide allows easy adaptation to different design solutions of household appliances.
