Abstract

The door lock has a retaining catch (1) provided on the door side, which is pivoted between a closed position and an open position via a grip handle (3) pivoted to the door and a cooperating locking device securing the retaining catch in the closed position. The grip handle is secured to the bearing part (2) of the retaining catch via a magnetic coupling (4,5,6), allowing it to move independently of the bearing part when the retaining catch is locked.

Description

Die Erfindung betrifft eine Türverriegelung, insbesondere für die Tür einer Wäschebehandlungsmaschine, mit einem türseitigen, als Rasthaken ausgebildeten Schließkloben und einem gehäuseseitigen Verschluss, mit einer an der Tür schwenkbar gelagerten Grifftaste, wobei durch die Schwenkbewegung der Schließkloben von einer Schließstellung in eine Öffnungsstellung überführbar ist, mit einer Verriegelungseinrichtung, in der der Schließkloben in seiner Schließstellung arretierbar ist, und mit einer Überreißsicherung, nach deren Auslösen ein Teil der Grifftaste von einem mit dem Schließkloben verbundenen Lagerteil lösbar und so von der der Schließstellung entsprechenden Lage in die der Öffnungsstellung entsprechende Lage überführbar ist.The invention relates to a door lock, in particular for the door of a laundry treatment machine, with a door-side, designed as latching hooks closing latch and a housing-side closure, with a pivotally mounted on the door handle key, which can be converted from a closed position to an open position by the pivotal movement of the closing with a locking device in which the locking block can be locked in its closed position, and with an over-tear, after the release of a part of the handle key of a locking member connected to the bearing part releasably and so from the closed position corresponding position in the open position corresponding position can be transferred ,

Eine solche Türverriegelung ist aus der DE 42 16 581 A1 bekannt. Sie wird außerdem beispielsweise bei einer von der Anmelderin hergestellten und unter der Bezeichnung WS 5080 vertriebenen Waschmaschine eingesetzt. Die Arretiervorrichtung ist bei dieser Waschmaschine zu dem Zweck vorgesehen, ein Öffnen der Tür während des Wasch- oder Schleuderbetriebes zu verhindern. Erfolgt aus Unkenntnis ein Öffnungsversuch während des Verriegelungszustandes, so neigt der Bediener dazu, wegen der Erfolglosigkeit seiner Bemühung verstärkt an der Grifftaste zu ziehen. Dabei kann der geräteseitige Verschluss unzulässig hoch belastet werden. Aus diesem Grund wurde die Grifftaste der WS 5080 mit einer Sollbruchstelle versehen, welche bei einer Kraft von mehr als 300 N zu einem Abreißen der Grifftaste führte. Hierdurch erfolgte eine Beschädigung des Geräts, welche eine Reparatur erforderlich machte und deshalb beim Kunden Unzufriedenheit auslöste.Such a door lock is known from DE 42 16 581 A1. It is also used, for example, in a washing machine manufactured by the applicant and sold under the name WS 5080. The locking device is provided in this washing machine for the purpose of preventing an opening of the door during the washing or spinning operation. If an opening attempt is made during the locked state due to ignorance, the operator tends to pull the handle button harder due to the failure of his effort. In this case, the device-side closure can be loaded unacceptably high. For this reason, the handle key of the WS 5080 was provided with a predetermined breaking point, which led to a break of the handle key at a force of more than 300 N. This resulted in damage to the device, which required repair and therefore caused customer dissatisfaction.

Deshalb ist in nachfolgenden Generationen eine Sicherheitskupplung als Überreißsicherung eingesetzt worden. Bei dieser Sicherheitskupplung wird in das Oberteil der Grifftaste eine Tasche eingesetzt, welche einen seitlich bewegbaren Rastschieber aufnimmt. Dieser Rastschieber steht unter Vorspannung, welche durch ein Federelement zwischen dem Schieber und der Seitenwand der Tasche erzeugt wird. Die dem Federelement gegenüberliegende Seite des Rastschiebers ist als dreieckige Nase ausgebildet, deren oberer Schenkel sich an einer Anlaufschräge am Lagerteil abstützt und so eine reib-/formschlüssige Verbindung zwischen Grifftastenoberteil und Lagerteil herstellt. Treten an der Grifftaste unzulässig hohe Zugkräfte auf, so verschiebt sich die Nase entlang der Anlaufschräge. Dabei wird das Federelement komprimiert und letztendlich die Verbindung zwischen Nase und Anlaufschräge gelöst. Hierdurch werden Grifftastenoberteil und Lagerteil entkoppelt. Bei dieser Sicherheitskupplung besteht der Nachteil, dass die durch das Federelement bewirkte Gegenkraft mit der Anzahl der Betätigungen sehr stark nachlässt. Dies hat seine Ursachen im Verschleiß der Nase und der Anlaufschräge und in der Alterung des Federelements. Außerdem ist durch die eingesetzten Reibpaarungen ein sehr großes Toleranzfenster für die Auslösekraft gegeben. Einstellungen können nicht vorgenommen werden.Therefore, in subsequent generations, a safety coupling has been used as over-tear protection. In this safety coupling, a pocket is used in the upper part of the handle button, which receives a laterally movable locking slide. This locking slide is biased, which is generated by a spring element between the slider and the side wall of the bag. The spring element opposite side of the locking slide is designed as a triangular nose, the upper leg is supported on a run-on slope on the bearing part and thus produces a frictional / positive connection between upper handle part and bearing part. If inadmissibly high tensile forces occur at the grip key, then the nose shifts along the run-up slope. The spring element is compressed and ultimately solved the connection between the nose and run-up slope. As a result, detent key top and bearing part are decoupled. In this safety coupling there is the disadvantage that the counterforce caused by the spring element decreases very much with the number of actuations. This has its causes in the wear of the nose and the run-on slope and in the aging of the spring element. In addition, given by the friction pairings used a very large tolerance window for the release force. Settings can not be made.

Ferner ist eine Türverriegelung mit einer Überreißsicherung aus EP 0 347 592 bekannt.Furthermore, a door lock with an over-tear protection from EP 0 347 592 is known.

Der Erfindung stellt sich somit das Problem, eine Türverriegelung der eingangs genannten Art zu offenbaren, bei der die Überreißsicherung nicht verschleißbehaftet ist.The invention thus provides the problem of disclosing a door lock of the type mentioned, in which the over-tear is not subject to wear.

Erfindungsgemäß wird dieses Problem durch eine Türverriegelung mit den Merkmalen des Patentanspruchs 1 gelöst. Eine zweckmäßige Ausgestaltung und Weiterbildung der Erfindung ergibt sich aus dem nachfolgenden Unteranspruch.According to the invention this problem is solved by a door lock with the features of claim 1. An expedient embodiment and development of the invention will become apparent from the following subclaim.

Die mit der Erfindung erreichbaren Vorteile bestehen darin, dass neben einer zeitlich unbegrenzten Alterungsbeständigkeit eine eng tolerierbare Auslösekraft eingehalten wird, wobei letztere zudem noch durch die Wahl des Magnetwerkstoffs und die Geometrie des Kupplungssystems sehr genau eingestellt werden kann.The achievable with the present invention consist in that in addition to a time-indefinite resistance to aging a closely tolerable release force is maintained, the latter can also be set very accurately by the choice of magnetic material and the geometry of the coupling system.

Ein Ausführungsbeispiel der Erfindung ist in einer Zeichnung rein schematisch dargestellt und wird nachfolgend näher beschrieben. Die Figur zeigt einen Schnitt durch den an der Tür angeordneten Teil einer Verriegelungseinrichtung einer Waschmaschine. Dieser Teil beinhaltet einen Schließkloben (1), der in einen in der Zeichnung nicht dargestellten gehäuseseitigen Verschluss eingreifen kann. In dieser Schließstellung kann der Schließkloben (1) durch eine ebenfalls nicht dargestellte Verriegelungseinrichtung arretiert werden. Der Verschluss- und Verriegelungsmechanismus ist aus der DE 42 16 581 A1 hinreichend bekannt und wird deshalb hier nicht näher beschrieben.An embodiment of the invention is shown purely schematically in a drawing and will be described in more detail below. The figure shows a section through the arranged on the door part of a locking device of a washing machine. This part includes a locking pin (1) which can engage in a housing-side closure, not shown in the drawing. In this closed position of the locking block (1) can be locked by a locking device, also not shown. The locking and locking mechanism is well known from DE 42 16 581 A1 and will therefore not be described here.

Mit dem Schließkloben (1) in Wirkverbindung steht ein Lagerteil (2), welches Teil einer schwenkbar an der Tür gelagerten Grifftaste ist. Durch die Schwenkbewegung des Lagerteils (2) wird der Schließkloben (1) im nicht arretierten Zustand von der Schließstellung in die Öffnungsstellung überführt. Ein weiterer Bestandteil der Grifftaste ist ein Grifftastenoberteil (3), welches mit dem Lagerteil (2) über eine nachfolgend beschriebene Überreißsicherung gekoppelt ist. Das Grifftastenoberteil (3) dient dem Bediener der Waschmaschine als Angriffshebel zur Bewegung des Lagerteils (2).With the locking block (1) in operative connection is a bearing part (2), which is part of a pivotally mounted on the door handle key. Due to the pivoting movement of the bearing part (2), the closing block (1) is transferred in the unlocked state from the closed position to the open position. Another component of the grip key is a handle key top (3), which is coupled to the bearing part (2) via an over-tear protection described below. The handle key top (3) serves the operator of the washing machine as an attack lever for moving the bearing part (2).

Die Überreißsicherung soll, wie bereits eingangs beschrieben, eine Beschädigung des Verschlusses verhindern, wenn das Grifftastenoberteil (3) bei arretiertem Schließkloben (1) bedient wird. Hierzu ist am Lagerteil (2) ein Stahltopf (4) angeordnet, in den ein Dauermagnet (5) eingeklebt ist. Am Grifftastenoberteil (3) ist in einer dem Dauermagneten (5) gegenüberliegenden Position eine Stahlplatte (6) angeordnet, die den magnetischen Rückschluss bildet und auf diese Weise als Magnetkupplung das Lagerteil (2) und das Grifftastenoberteil (3) verbindet.The over-rupture should, as already described, prevent damage to the closure when the handle key shell (3) is operated with locked lock (1). For this purpose, a steel pot (4) is arranged on the bearing part (2), in which a permanent magnet (5) is glued. At the handle key top (3) a steel plate (6) is arranged in a position opposite the permanent magnet (5), which forms the magnetic yoke and in this way connects the bearing part (2) and the handle key top (3) as magnetic coupling.

Wird nun bei arretiertem Schließkloben (1) an der Grifftaste gezogen, so wird mit dem Überschreiten einer definierten Zugkraft von ca. 150 N die Stahlplatte (6) vom Stahltopf (4) bzw. vom Magneten (5) gelöst und damit die Kupplung zwischen Grifftastenoberteil (3) und Lagerteil (2) gelöst.If the locking button (1) is now pulled on the handle button, the steel plate (6) is released from the steel pot (4) or the magnet (5) by exceeding a defined tensile force of approx. 150 N, thus releasing the coupling between the upper part of the handle (3) and bearing part (2) solved.

Zur erneuten Verbindung dieser beiden Teile wird das Grifftastenoberteil (3) ohne Kraftaufwand auf das Lagerteil (2) geschwenkt.To reconnect these two parts of the handle key shell (3) is pivoted without effort on the bearing part (2).

Es besteht natürlich die Möglichkeit, die Magnetkupplung derart aufzubauen, dass der Stahltopf mit Magnet am Grifftastenoberteil und die Stahlplatte am Lagerteil befestigt sind. Dies hat auf die Funktion keine Auswirkung. Bei Verwendung von magnetischen Werkstoffen im Bereich Lagerteil und Grifftastenoberteil kann die Funktion der Stahlplatte und des Stahltopfes von den Griffteilen selbst übernommen werden.Of course, it is possible to construct the magnetic coupling in such a way that the steel pot with magnet is fastened to the handle key top and the steel plate is fastened to the bearing part. This has no effect on the function. When using magnetic materials in the area bearing part and handle top part, the function of the steel plate and the steel pot can be taken over by the handle parts themselves.
