Description

Die Erfindung bezieht sich auf ein Mehrgelenkscharnier, insbesondere für Kühlschranktüren, bestehend aus scherenartig miteinander verbundene Gelenkhebeln.The invention relates to a multi-joint hinge, in particular for refrigerator doors, consisting of scissor-like interconnected articulated levers.

Derartige Scharniere sind im Stand der Technik zahlreich bekannt, z.B. durch das Patent GB 1 066 710 , US 5 035 026 oder US 5791016 .Such hinges are well known in the art, eg by the patent GB 1 066 710 . US 5 035 026 or US 5791016 ,

Die bekannten Scharniere haben jedoch verschiedene Nachteile.However, the known hinges have several disadvantages.

Da insbes. bei Kühlschränken, wegen der thermischen Isolierung, sehr dicke Türkörper verwendet werden, müssen die Scharniere relativ lange Gelenkhebel aufweisen, um die gewünschte Ausladung - weg vom Korpus nach vom - zu erreichen. Dieses führt dazu, dass zwischen den Gelenkhebeln je nach Offenstellung unterschiedlich große Spalten entstehen, die sich bei der Bewegung der Tür vergrößern oder verkleinern können. Im Falle der Verkleinerung würde sich eine Verletzungsgefahr ergeben, wenn z.B. ein Kind einen Finger hineinstecken würde. In diesem Falle würden die scherenartig verbundenen Gelenkhebel wie eine Schneid-Schere wirken.Since, in particular, for refrigerators, because of the thermal insulation, very thick door body are used, the hinges must have relatively long articulated levers in order to achieve the desired projection - away from the body to -. This results in different sized gaps between the articulated levers, depending on the open position, which can increase or decrease as the door moves. In the case of reduction, there would be a risk of injury if e.g. a child would put a finger in it. In this case, the scissors-like joint levers would act like a pair of cutting scissors.

Es ist deshalb eine Aufgabe der Erfindung diesen Mangel zu beseitigen.It is therefore an object of the invention to remedy this deficiency.

Diese Aufgabe wird bei einem Mehrgelenkscharnier, durch die technichen Merkmale des Anspruchs 1 gelöst.This object is achieved in a multi-joint hinge, by the technical features of claim 1.

Damit ist die Gefahr der Verletzungen durch Einklemmen und Abscheren zwischen den Gelenkhebeln praktisch verhindert.Thus, the risk of injury from pinching and shearing between the articulated levers is virtually prevented.

Weitere Merkmale der Erfindung sind Gegenstand von Unteransprüchen.Further features of the invention are the subject of dependent claims.

In den Figuren sowie in der weiteren Beschreibung sind Ausführungsbeispiele der Erfindung beschrieben.Exemplary embodiments of the invention are described in the figures and in the further description.

Wie Figur 1 zeigt, besteht das Scharnier zunächst aus zwei Befestigungsteilen 1, 2 von dem eines am Korpus (nicht dargestellt) befestigt ist. Wie aus Figur 2 deutlich ersichtlich, sind die Befestigungsteile 1, 2 durch Hebel miteinander getriebemäßig verbunden. Bei dem gezeigten Ausführungsbeispiel sind am Befestigungsteil 1 mit Abstand voneinander zwei Gelenkhebel 4, 5 mittels Gelenkstellen 7, 8 schwenkbar verbunden. An den freien Enden sind die Gelenkhebel 4, 5 mittels Gelenkstellen 9, 10 mit einem Scharnierarm 3 verbunden, der an seinem freien Ende mit dem Befestigungsteil 2 mittels Gelenkstellen 11, 12 verbunden ist. Der Gelenkhebel 4 weist im mittleren Bereich eine Gelenkstelle 21 auf, die mit einem Gelenkhebel 6 verbunden ist. Der Gelenkhebel 6 ist an seinem freien Ende mittels der Gelenkstelle 12 drehbar mit dem Befestigungsteil 2 verbunden.As FIG. 1 shows, the hinge consists first of two fastening parts 1, 2 of which one on the body (not shown) is attached. How out FIG. 2 clearly seen, the fastening parts 1, 2 are connected to each other by levers gear. In the embodiment shown, two articulated levers 4, 5 are pivotably connected by means of hinge points 7, 8 on the fastening part 1 at a distance from each other. At the free ends of the articulated levers 4, 5 are connected by means of joints 9, 10 with a hinge arm 3, which is connected at its free end to the fastening part 2 by means of joints 11, 12. The articulated lever 4 has in the central region a hinge point 21 which is connected to a hinge lever 6. The articulated lever 6 is rotatably connected at its free end by means of the hinge point 12 with the fastening part 2.

Wie aus Figur 2 ersichtlich, ist der Gelenkhebel 5 im Bereich der Gelenkstelle 10 mit einer Steuerkurve 13 verbunden, die an einem am Scharnierarm 3 festgelegten Kurvenkörper 22 ausgebildet ist, dessen Konturierung zur Erzielung anderer Kraftverläufe auch von der in Figur 2 dargestellten Form abweichen kann.How out FIG. 2 it can be seen, the articulated lever 5 is connected in the region of the hinge point 10 with a control cam 13 which is formed on a fixed to the hinge arm 3 cam body 22, the contouring to achieve other force profiles from the in FIG. 2 may differ form shown.

Benachbart der Gelenkstelle 10 ist ein Kipphebel 14 schwenkbar in einen Drehpunkt 23 gelagert. Im gezeigten Ausführungsbeispiel steht der Kipphebel entgegen dem Uhrzeigersinn unter dem Druck einer Feder 17. Am Kipphebel ist eine Druckrolle 24 gelagert die mit der Steuerkurve in Kontakt steht.Adjacent to the hinge point 10, a rocker arm 14 is pivotally mounted in a pivot point 23. In the illustrated embodiment, the rocker arm is counterclockwise under the pressure of a spring 17. On the rocker arm, a pressure roller 24 is mounted which is in contact with the control cam.

Wie aus Figur 1 ersichtlich ist der Kipphebel mit einer Stellschraube 16 versehen. Der Schraubenkopf der Stellschraube 16 ist mittels eines Durchbruchs 25 im Gelenkhebel 5 für einen Schraubendreher oder dergleichen zugänglich. Wird die Schraube weiter aus dem Kipphebel heraus geschraubt, schlägt der Schraubenkopf an den Gelenkhebel 5 an und begrenzt die Drehung des Kipphebel 14 und verändert die Kennlinie des Federverhaltens. Mittels der Stellschraube kann der Kipphebel auch soweit gedreht werden, dass die Federwirkung aufgehoben wird.How out FIG. 1 it can be seen that the rocker arm is provided with a set screw 16. The screw head of the adjusting screw 16 is accessible by means of an opening 25 in the articulated lever 5 for a screwdriver or the like. If the screw further screwed out of the rocker arm, the screw head abuts against the hinge lever 5 and limits the rotation of the rocker arm 14 and changed the characteristic of the spring behavior. By means of the adjusting screw, the rocker arm can also be turned so far that the spring action is canceled.

In den Figur 3 und 4 ist ein weiteres Ausführungsbeispiel gezeigt. Seitlich an dem Scharnier ist eine Schutzplatte 15 angebracht. Diese ist im ersten Endbereich mit einer Anlenkstelle 18 drehbar an dem Befestigungsteil 2 gelagert und im gegenüberliegenden Endbereich mit einem Langloch 20 versehen, welches die Führung auf einen Führungszapfen 19 führt. Dieser Führungszapfen ist in dem gezeigten Ausführungsbeispiel am Gelenkhebel 5 ausgebildet, könnte jedoch auch je nach Scharnierkinematik an anderen Bauteilen ausgebildet sein.In the FIG. 3 and 4 another embodiment is shown. Laterally on the hinge, a protective plate 15 is attached. This is rotatably mounted in the first end region with an articulation point 18 on the fastening part 2 and provided in the opposite end region with a slot 20 which guides the guide on a guide pin 19. This guide pin is formed in the illustrated embodiment, the hinge lever 5, but could also be formed depending on the hinge kinematics on other components.

Die Anlenkstelle 18 und/oder der Führungszapfen 19 ist/sind vorteilhafterweise durch eine Verlängerung der die Gelenkhebel gelenkig miteinander verbindenden Gelenkstifte gebildet.The articulation point 18 and / or the guide pin 19 is / are advantageously formed by an extension of the hinge lever pivotally interconnecting hinge pins.

Diese Schutzplatte 15 kann je nach Einbauart oder Verwendung des Scharniers nur auf einer Seite angeordnet sein, aber auch auf beiden Seiten des Scharniers. Es liegt auch im Rahmen der Erfindung, bei Einsatz von zwei Schutzplatten, diese scharnierübergreifend U-förmig miteinander zu verbinden.This protective plate 15 may be arranged depending on the installation or use of the hinge only on one side, but also on both sides of the hinge. It is also within the scope of the invention, with the use of two protective plates to connect these hinge-overlapping U-shaped with each other.
