Description

Die Erfindung betrifft ein Scharniergelenk für Türen oder Klappen, vorzugsweise zum Anlenken einer Tür an ein Kühl- und/oder Gefriergerät, deren korpusfester Scharnierteil mit dem beweglichen Scharnierteil durch mehrere Lenker und/oder mindestens einen Gelenkhebel schwenkbar verbunden ist, von denen mindestens ein Lenker oder ein Gelenkhebel derart von einer Feder beaufschlagt ist, daß diese das bewegliche Scharnierteil mindestens im Bereich der Öffnungsstellung in Richtung auf diese Öffnungsstellung belastet.The invention relates to a hinge joint for doors or flaps, preferably to link a door to a refrigerator and / or freezer, the body-more resistant Hinge part with the movable hinge part by several handlebars and / or at least one articulated lever is pivotally connected, at least of which a handlebar or an articulated lever is acted upon by a spring such that this the movable hinge part in at least in the open position Direction towards this open position.

Scharniergelenke dieser Art werden vorzugsweise in den Fällen eingesetzt, in denen ein die Tür in die geöffnete Stellung drückendes Moment erwünscht ist. Andererseits übt die Feder auf die Tür im Öffnungsbereich ein Öffnungsmoment aus, aufgrund dessen die Tür unter Stoßwirkung in die Öffnungsstellung schlagen kann. Ein derartiges Schlagen der Tür in die Öffnungsstellung ist jedoch insbesondere bei Kühlgeräten nachteilig, da die Türen von Kühlgeräten üblicherweise mit Abstelleinrichtungen beispielsweise für Flaschen versehen sind, so daß diese unter der Stoßwirkung beim Anschlagen in die Öffnungsstellung der Tür aneinanderstoßen und zerbrechen können. Hinge joints of this type are preferably used in the cases in for whom a moment pushing the door into the open position is desired. On the other hand, the spring exerts an opening moment on the door in the opening area due to which the door bump into the open position under impact can. Such a beating of the door in the open position is, however particularly disadvantageous in cooling units, since the doors of cooling units are usually provided with storage facilities, for example for bottles, so that this under the impact when struck in the open position Can knock against each other and break.

Aufgabe der Erfindung ist es daher, ein Scharniergelenk der eingangs angegebenen Art zu schaffen, bei dem trotz des in der Öffnungsstellung vorhandenen Öffnungsmoments ein Schlagen der Tür unter Stoßwirkung in die Öffnungsstellung verhindert, zumindest jedoch abgemildert ist.The object of the invention is therefore a hinge joint of the beginning specified type to create, despite the in the open position existing opening moment a knocking of the door under impact Opening position is prevented, but at least mitigated.

Erfindungsgemäß wird diese Aufgabe bei einem Scharniergelenk der eingangs angegebenen Art dadurch gelöst, daß Brems- und/oder Dämpfungsmittel vorgesehen sind, die ein hartes Aneinanderschlagen von Scharnierteilen und/oder Lenkern in der Öffnungsstellung dämpfen oder verhindern.According to the invention, this object is achieved with a hinge joint specified type solved in that braking and / or damping means are provided, the hard hitting together of hinge parts and / or Cushion or prevent handlebars in the open position.

Die erfindungsgemäß vorgesehenen Brems- und/oder Dämpfungsmittel heben das durch die Feder im Öffnungsbereich der Tür oder Klappe ausgeübte Öffnungsmoment nicht auf. Sie dämpfen jedoch das Schlagen der von der Feder beschleunigten Tür in die Öffnungsstellung in der Weise, daß ein unerwünschtes Ausmaß an Schlagenergie aufgezehrt oder abgebremst wird.The braking and / or damping means provided according to the invention raise this exerted by the spring in the opening area of the door or flap Opening moment does not open. However, they dampen the hitting of the feather accelerated door to the open position in such a way that an undesirable Extent of impact energy is consumed or slowed down.

Bei dem erfindungsgemäßen Scharniergelenk kann das schwenkbare Scharnierteil durch zwei Lenker mit einem Gelenkhebel verbunden sein, der an das korpusfeste Scharnierteil angelenkt ist, wobei der dem korpusfesten Scharnierteil zugewandte Lenker durch einen dritten Lenker mit dem korpusfesten Scharnierteil verbunden ist und wobei zwischen dem ersten und dem zweiten Lenker eine Druckfeder eingespannt ist, die zwischen der Öffnungs- und Schließstellung eine Totpunktstellung durchläuft. Bei diesem erfindungsgemäß eingesetzten Scharnier bewirkt die Feder beidseits der Totpunktstellung, daß die Tür einmal ein Öffnungsmoment in Richtung auf die Öffnungsstellung und zum anderen ein Schließmoment in Richtung auf die Schließstellung erfährt. Bei einem Kühlschrankscharnier, bei dem eine Feder auch ein Schließmoment erzeugt, sind jedoch grundsätzlich keine besonderen Maßnahmen erforderlich, um eine Schlagwirkung im Schließbereich zu dämpfen, weil der Schlag beim Schließen der Gerätetür durch die Türdichtung gedämpft wird. In the hinge joint according to the invention, the pivotable hinge part be connected by two links with an articulated lever attached to the body-fixed Hinge part is articulated, the one facing the body-fixed hinge part Handlebar is connected by a third handlebar to the body-fixed hinge part and wherein a compression spring between the first and the second link is clamped between the open and closed positions Dead center passes through. With this hinge used according to the invention the spring on both sides of the dead center position causes the door to open once Opening moment in the direction of the opening position and the other Experiences closing torque in the direction of the closed position. At a Fridge hinge, in which a spring also generates a closing moment however, in principle no special measures are required to achieve a To dampen the impact in the closing area because the impact when closing the Appliance door is dampened by the door seal.

Bei diesem vorzugsweise eingesetzten Scharniergelenk können der Gelenkhebel und der dritte Lenker annähernd parallel zueinander verlaufen. Weiterhin können der erste und der zweite Lenker zumindest in einer Mittelstellung parallel zueinander verlaufen.With this hinge joint, which is preferably used, the articulated lever can and the third link is approximately parallel to each other. Can continue the first and the second link parallel at least in a central position to each other.

Nach einer bevorzugten Ausführungsform ist vorgesehen, daß die Brems- und/oder Dämpfungsmittel aus einer Feder bestehen, die erst am Ende der Öffnungsbewegung durch die Lenker und/oder den Gelenkhebel gespannt wird.According to a preferred embodiment it is provided that the braking and / or Damping means consist of a spring that only at the end of Opening movement is tensioned by the handlebars and / or the articulated lever.

Die Feder besteht zweckmäßigerweise aus mindestens einer auf die Schwenkachse des Gelenkhebels aufgesetzten Schenkelfeder, deren einer Schenkel sich an dem Gelenkhebel und deren anderer Schenkel sich an dem korpusfesten Scharnierteil abstützt. Die Abstützung an dem korpusfesten Scharnierteil kann auf einem mit diesem verbundenen Bolzen erfolgen.The spring advantageously consists of at least one on the Swivel axis of the articulated lever attached leg spring, one of which Leg itself on the articulated lever and its other leg on the supporting body-fixed hinge part. The support on the body-fixed Hinge part can be made on a bolt connected to this.

Um die Dämpfungswirkung der Feder in der erforderlichen oder gewünschten Weise einstellen zu können, kann eine Einrichtung zur Einstellung des Schwenkwinkels vorgesehen sein, bei dem der Gelenkhebel beginnt, spannend auf die Feder einzuwirken. Die Einstellrichtung kann aus einer an dem Gelenkhebel angeordneten Stellschraube oder einem einstellbaren Exzenter bestehen.To the damping effect of the spring in the required or desired To be able to set a device for setting the Swivel angle can be provided, at which the articulated lever begins, exciting to act on the spring. The setting direction can be from a on the articulated lever arranged set screw or an adjustable eccentric.

Nach einer anderen Ausführungsform kann die Dämpfungseinrichtung aus einer zwischen dem Gelenkhebel oder dem dritten Lenker und dem korpusfesten Scharnierteil angeordneten Kolben-Zylinder-Einheit bestehen, die mit einem den Schlag dämpfenden Medium, beispielsweise einem Gas oder Öl, gefüllt ist. Besteht die Dämpfungseinrichtung aus einer mit Öl gefüllten Kolben-Zylinder-Einheit, wird der Kolben zweckmäßigerweise mit einer Bohrung versehen, durch die das Öl von einer Kolbenkammer in die anderen unter Drosselwirkung eintritt.According to another embodiment, the damping device can consist of a between the articulated lever or the third handlebar and the body-fixed Hinge part arranged piston-cylinder unit consist of one with the Impact damping medium, for example a gas or oil, is filled. Consists the damping device from a piston-cylinder unit filled with oil the piston expediently provided with a bore through which the oil from one piston chamber enters the other under throttling action.

Nach einer weiteren Ausführungsform ist vorgesehen, daß die Dämpfungseinrichtung aus zwischen den Lenkern und/oder dem Gelenkhebel und/oder dem korpusfesten oder verschwenkbaren Scharnierteilen angeordneten Reib- und/oder Bremsbelägen bestehen.According to a further embodiment it is provided that the Damping device from between the handlebars and / or the articulated lever and / or the body-fixed or pivotable hinge parts Friction and / or brake pads exist.
