Scharnier für Kühl- und GefrierschränkeHinge for refrigerators and freezers

Bei Kühlschränken ist es bekannt, die Schranktür in geschlossenem Zustand durch Magnetwirkung festzuhalten. Die Magnetwirkung funktioniert jedoch erst, wenn die Schranktür sich praktisch in der Schliesslage befindet. Wenn die Schranktür unbeabsichtigt nicht vollständig geschlossen wir, kann das für das Kühlaggregat eine unnötige Dauerbelastung bedeuten. Zudem kann Feuchtigkeit in das Schrankinnere eindringen, was zur Eisbildung führt und beim Abtauen grössere Mengen Kondenswasser anfallen lässt. Ausserdem bewirkt dies einen nutzlosen Strommehrverbrauch.It is well known that refrigerators use magnets to hold the cabinet door closed. However, the magnets only work when the cabinet door is practically in the closed position. If the cabinet door is accidentally not closed completely, this can mean an unnecessary, continuous load for the cooling unit. Moisture can also penetrate the interior of the cabinet, which leads to ice formation and large amounts of condensation during defrosting. This also results in unnecessary additional electricity consumption.

Mit der Neuerung soll die Aufgabe gelöst werden, ein in die Schranktür leicht einbaubares Scharnier zu schaffen, das bewirkt, dass die Schranktür sicher in die Schliesslage gezogen wird, wenn der Tür-Öffnungswinkel gering ist.The innovation is intended to solve the problem of creating a hinge that can be easily installed in the cabinet door and that ensures that the cabinet door is safely pulled into the closed position when the door opening angle is small.

Die Neuerung, mit der diese Aufgabe gelöst wird, ergibt sich aus dem Kennzeichen des Anspruches 1.The innovation with which this problem is solved results from the characterizing part of claim 1.

. · ff »&Ogr; ·. · ff »&Ogr; ·

Die federbelastete Nockenrolle liegt gegen einen Nocken des mit dem Schrankgehäuse starr verbundenen Scharnierhebels an. Die Ausbildung des Nockens ist derart getroffen, dass bei einem Öffnungswinkel der Schranktür von weniger als etwa 9° auf die Schranktür durch die federbelastete Nockenrolle eine in Schliessrichtung wirkende Kraft entsteht, sodass eine unbeabsichtigte Offenlage der Schranktür mit Sicherheit vermieden wird. Andererseits hat die Tür bei einem grösseren Öffnungswinkel nicht die unangenehme Tendenz, sich schliessen zu wollen, wie dies bei einem blossen Federzug unumgänglich wäre.The spring-loaded cam roller rests against a cam on the hinge lever, which is rigidly connected to the cabinet housing. The cam is designed in such a way that when the cabinet door is opened at an angle of less than about 9°, the spring-loaded cam roller exerts a force on the cabinet door in the closing direction, so that the cabinet door is prevented from being opened accidentally. On the other hand, when the door is opened at a larger angle, it does not have the unpleasant tendency to want to close, as would be unavoidable with a simple spring pull.

In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Neuerung dargestellt und wird nachfolgend näher beschrieben.
Es zeigen:
An embodiment of the subject matter of the innovation is shown in the drawing and is described in more detail below.
Show it:

Fig. 1 einen Ausschnitt des oberen Eckbereiches eines Kühlschrankes mit geöffneter Schranktür und Scharnier,Fig. 1 a section of the upper corner area of a refrigerator with open cabinet door and hinge,

Fig. 2 einen Horizontal schnitt durch das Scharnier bei geöffneter Schranktür,Fig. 2 a horizontal section through the hinge with the cabinet door open,

Fig.3 einen Horizontalschnitt durch das Scharnier im Kippunkt,Fig.3 a horizontal section through the hinge at the tipping point,

Fig.4 einen Horizontalschnitt durch das Scharnier in der Schliesslage der Schranktür.Fig.4 a horizontal section through the hinge in the closed position of the cabinet door.

Das Scharnier ist - gemäss Fig.l - zur drehbaren Befestigung einer Schranktür 2 an einem Kühl- oder Gefrierschrankgehäuse 3 bestimmt. Die gleiche Scharnierausbildung kann oben und unten verwendet werden; üblicherweise genügt es, wenn nur das eine Scharnier federbelastet wird.The hinge is designed - as shown in Fig. 1 - for the pivotable fastening of a cabinet door 2 to a refrigerator or freezer housing 3. The same hinge design can be used at the top and bottom; it is usually sufficient if only one hinge is spring-loaded.

Mit dem Schrankgehäuse 3 ist ein erster L-förmiger Schenkel 6 des Scharnierhebels 4 mittels eines abgekröpften Befestigungsteiles 5 durch Nieten oder Schrauben starr verbunden. Der Scharnierhebel 4 durchdringt einen Schlitz 7 in der Schranktür 2 und ist mit einer Achse 8 in der Schranktür 2 drehbar befestigt. Die Achse 8 befindet sich nahe bei der Türecke am Ende des zweiten L-Schenkels 9. ImA first L-shaped leg 6 of the hinge lever 4 is rigidly connected to the cabinet housing 3 by means of a cranked fastening part 5 by rivets or screws. The hinge lever 4 penetrates a slot 7 in the cabinet door 2 and is rotatably fastened to an axis 8 in the cabinet door 2. The axis 8 is located close to the corner of the door at the end of the second L-leg 9. In the

Eckbereich zwischen den beiden L-Schenkeln 6 und 9 ist ein vorstehender, gerundeter Nocken 10 vorhanden. Dieser Nocken 10 wirkt mit einer federbelasteten Nockenrolle 12 zusammen. Diese Nockenrolle 12 wird drehbar von einer Rollenachse 14 gehalten, die mit einer Führungshülse 16 verbunden ist. Die Führungshülse 16 ist verschiebbar auf einem Zylinderbolzen 18 gehalten, der an einem Lagerdeckel 20 abgestützt wird. Zwischen Schultern der Führungshülse 16 und dem Zylinderbolzen 18 befindet sich eine Wendelfeder 22, die bestrebt ist, die Nockenrolle 12 gegen den Nocken 10 anzudrücken und diesen nach auswärts zu schieben.In the corner area between the two L-legs 6 and 9 there is a protruding, rounded cam 10. This cam 10 interacts with a spring-loaded cam roller 12. This cam roller 12 is held rotatably by a roller axis 14, which is connected to a guide sleeve 16. The guide sleeve 16 is slidably held on a cylinder bolt 18, which is supported on a bearing cover 20. Between the shoulders of the guide sleeve 16 and the cylinder bolt 18 there is a coil spring 22, which strives to press the cam roller 12 against the cam 10 and push it outwards.

In Fig.2 hat die Schranktür einen Öffnungswinkel von etwa 20°. In dieser Position kommt die Nockenrolle 12 gerade zum Anliegen gegen den Nocken 10. Wenn die Schranktür 2 weiter geöffnet wird, bleibt dies ohne Wirkung zwischen Nockenrolle 12 und Nocken 10, d.h. auf die Schranktür 2 wirkt keine Kraft in Schliessrichtung.In Fig.2, the cabinet door has an opening angle of about 20°. In this position, the cam roller 12 just comes to rest against the cam 10. If the cabinet door 2 is opened further, this has no effect between the cam roller 12 and the cam 10, i.e. no force acts on the cabinet door 2 in the closing direction.

Wenn die Schranktür 2 - ausgehend von der in Fig.2 dargestellten Lage - in Schliessrichtung bewegt wird, rollt die Nockenrolle 12 auf dem Nocken 10 ab, bis der Kippunkt erreicht wird, wobei die Feder 22 gespannt wird. In der in Fig.3 dargestellten Lage ist der Kippunkt erreicht, wobei der Öffnungswinkel der Schranktür 2 etwa 9° beträgt. Bei einer Weiterbewegung der Schranktür 2 in Schliessrichtung bewirkt die gespannte Feder beim Abrollen auf den Nocken 10 eine Kraft in Schliessrichtung der Schranktür 2, bis schliesslich die in Fig.4 dargestellt vollständige Schliessposition der Schranktür 2 erreicht ist, wobei eine geringe Restspannung in Schliessrichtung verbleibt. Dadurch wird vermieden, dass die Schranktür 2 versehentlich einen Spalt offen bleibt.When the cabinet door 2 is moved in the closing direction starting from the position shown in Fig.2, the cam roller 12 rolls on the cam 10 until the tipping point is reached, whereby the spring 22 is tensioned. In the position shown in Fig.3, the tipping point is reached, whereby the opening angle of the cabinet door 2 is approximately 9°. When the cabinet door 2 continues to move in the closing direction, the tensioned spring causes a force in the closing direction of the cabinet door 2 when it rolls on the cam 10 until the fully closed position of the cabinet door 2 shown in Fig.4 is finally reached, whereby a small residual tension remains in the closing direction. This prevents the cabinet door 2 from accidentally being left open a crack.
