Ein derartiges Kühl- und/oder Gefriergerät ist aus dem Stand der Technik bekannt. Die U.S. 6,845,545 B2 offenbart ein Kühlgerät, in dessen Fußbereich ein Dämpfer angeordnet ist, der aus einem in einem Zylinder verschieblich aufgenommenen Kolben besteht, der mittels einer Kolbenstange beim Schließen der Tür in den Zylinder eingeschoben wird. Der Zylinder ist schwenkbar an dem Korpus des Gerätes angeordnet und erstreckt sich im wesentlichen parallel zur Geräteseitenwand. Das aus der U.S. 6,845,545 B2 bekannte Kühlgerät weist des weiteren Mittel zum Erzeugen einer Schließkraft auf, die durch eine Schraubenfeder gebildet werden, die beim Öffnen der Tür gespannt wird und für einen vorgegebenen Winkelbereich eine Schließkraft auf die Tür oder Klappe ausübt, so dass in dem genannten Winkelbereich ein selbsttätiges und gedämpftes Schließen der Tür erfolgt.Such a refrigerator and / or freezer is known from the prior art. The US 6,845,545 B2 discloses a refrigerator, in whose foot a damper is arranged, which consists of a slidably received in a cylinder piston which is inserted by means of a piston rod when closing the door into the cylinder. The cylinder is pivotally mounted on the body of the device and extends substantially parallel to the device side wall. That from the US 6,845,545 B2 known cooling device further comprises means for generating a closing force, which are formed by a coil spring, which is tensioned when opening the door and for a predetermined angular range exerts a closing force on the door or flap, so that in the said angular range an automatic and damped Close the door.

Die DE 296 11 392 U1 offenbart ein Kühl- und/oder Gefriergerät, das sämtliche Merkmale des Oberbegriffs des Anspruchs 1 offenbart.The DE 296 11 392 U1 discloses a refrigerator and / or freezer, which discloses all features of the preamble of claim 1.

Es ist die Aufgabe der vorliegenden Erfindung, ein Kühl- und/oder Gefriergerät der eingangs genannten Art dahingehend zu verbessern, dass bei einem Öffnungswinkel der Tür oder Klappe oberhalb eines bestimmten Winkels die Tür oder Klappe in ihrer durch den Nutzer des Gerätes bestimmten Position stehen bleibt und dass bei einem Öffnungswinkel der Tür oder Klappe unterhalb des bestimmten Winkels ein selbsttätiges Schließen der Tür oder Klappe erfolgt.It is the object of the present invention to improve a refrigerator and / or freezer of the type mentioned in that at an opening angle of the door or flap above a certain angle the door or flap stops in its determined by the user of the device position and that at an opening angle of the door or flap below the certain angle, an automatic closing of the door or flap takes place.

Diese Aufgabe wird durch ein Kühl- und/oder Gefriergerät mit den Merkmalen des Anspruchs 1 gelöst. Danach ist unter anderem vorgesehen, dass das Scharnier Mittel zum Erzeugen einer Schließkraft aufweist, wobei die Mittel zum Erzeugen einer Schließkraft einen Exzenter sowie Mittel aufweisen, die eine auf den Exzenter wirkende und vom Öffnungswinkel der Tür oder Klappe abhängige Kraft erzeugen. Erfindungsgemäß ist somit vorgesehen, dass in Abhängigkeit vom Öffnungswinkel eine Schließkraft auf die Tür oder Klappe wirkt, die dadurch hervorgerufen wird, dass auf einen Exzenter des Scharniers eine Kraft ausgeübt wird.This object is achieved by a refrigerator and / or freezer with the features of claim 1. Thereafter, inter alia, provided that the hinge has means for generating a closing force, wherein the means for generating a closing force having an eccentric and means which generate a force acting on the eccentric and dependent on the opening angle of the door or flap force. According to the invention it is thus provided that, depending on the opening angle, a closing force acting on the door or flap, which is caused by the fact that a force is exerted on an eccentric of the hinge.

Denkbar ist es beispielsweise, dass der Exzenter derart ausgeführt ist, dass über einem Öffnungswinkel von 55° keine eine Schließbewegung hervorrufenden Kräfte mehr auf die Tür oder Klappe einwirken. Somit verbleibt die Tür oder Klappe in der Stellung, in die sie durch den Nutzer gebracht wurde. Dadurch wird verhindert, dass die Tür ab einem bestimmten Öffnungswinkel sich automatisch in die geöffnete Endlage bewegt oder automatisch geschlossen wird. Somit können Beschädigungen am Gerät, die ggf. durch ein ungewolltes Öffnen der Tür hervorgerufen werden, verhindert werden.It is conceivable, for example, that the eccentric is designed in such a way that, over an opening angle of 55 °, no forces inducing a closing movement act more on the door or flap. Thus, the door or flap remains in the position in which it was brought by the user. This prevents the door from automatically moving to the open end position after a certain opening angle or being automatically closed. Thus, damage to the device, which may be caused by accidental opening of the door, can be prevented.

Die Mittel, die eine auf den Exzenter wirkende Kraft erzeugen, können derart ausgeführt und angeordnet sein, dass sie auf die Oberfläche des Exzenters eine Druckkraft ausüben. Dabei kann der Exzenter derart ausgeführt und angeordnet sein, dass die Druckkraft in einem ersten Winkelbereich auf den Exzenter kein Drehmoment erzeugt, so dass die Tür oder Klappe stehen bleibt und in einem zweiten Winkelbereich auf den Exzenter ein Drehmoment erzeugt, das zum Schließen der Tür oder Klappe führt.The means which generate a force acting on the eccentric, can be designed and arranged such that they exert a compressive force on the surface of the eccentric. In this case, the eccentric be designed and arranged such that the compressive force in a first angular range on the eccentric no Torque generated so that the door or flap stops and generates a torque in a second angular range on the eccentric, which leads to the closing of the door or flap.

Nach der Erfindung weist das Scharnier einen ersten Scharnierhebel und einen zweiten Scharnierhebel auf, von denen einer schwenkbar mit der Tür oder Klappe und der andere schwenkbar mit dem Korpus der Gerätes in Verbindung steht, wobei der Exzenter sowie die Mittel, die eine auf den Exzenter wirkende Kraft erzeugen, jeweils an einem der Scharnierhebel oder beide an einem der Scharnierhebel schwenkbar angeordnet sind.According to the invention, the hinge has a first hinge lever and a second hinge lever, one of which is pivotally connected to the door or flap and the other pivotally connected to the body of the device, wherein the eccentric and the means acting on the eccentric one Generate force, each pivotally mounted on one of the hinge lever or both on one of the hinge lever.

Erfindungsgemäß ist vorgesehen, dass das Scharnier einen ersten Scharnierhebel und einen zweiten Scharnierhebel aufweist, von denen einer schwenkbar mit der Tür oder Klappe und der andere schwenkbar mit dem Korpus des Gerätes in Verbindung steht, und dass das Scharnier ferner einen Zughebel aufweist, der schwenkbar an dem Exzenter sowie an einem der Scharnierhebel angeordnet ist. Vorzugsweise fällt die Achse, an der der Zughebel an dem Exzenter angelenkt ist, nicht mit der Drehachse des Exzenters zusammen. Über den Zughebel wird das auf den Exzenter wirkende Drehmoment in eine Kraft umgesetzt, die zum Schließen der Tür oder Klappe führt.According to the invention it is provided that the hinge has a first hinge lever and a second hinge lever, one of which is pivotally connected to the door or flap and the other pivotally connected to the body of the device, and in that the hinge further comprises a pull lever which pivotally the eccentric and on one of the hinge lever is arranged. Preferably, the axis at which the pull lever is articulated to the eccentric, does not coincide with the axis of rotation of the eccentric. About the pull lever, the torque acting on the eccentric is converted into a force that leads to the closing of the door or flap.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Mittel, die eine auf den Exzenter wirkende Kraft erzeugen, eine oder mehrere Druckfedern aufweisen sowie eine Rolle oder ein Gleitelement, die/das auf der Oberfläche des Exzenters läuft bzw. auf diese einwirkt.In a further embodiment of the invention, it is provided that the means which generate a force acting on the eccentric, one or more compression springs and a roller or a sliding element which runs on the surface of the eccentric and acts on these.

In weiterer Ausgestaltung der Erfindung sind die Mittel, die eine auf den Exzenter wirkende Kraft ausüben, als Blattfedern, Schenkelfedern, Spiralfedern oder Schraubenfedern ausgeführt.In a further embodiment of the invention, the means which exert a force acting on the eccentric force, designed as leaf springs, torsion springs, coil springs or coil springs.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass der Dämpfer einen in einem Zylinder laufenden Kolben und eine mit dem Kolben in Verbindung stehende Kolbenstange aufweist, die an dem Scharnier angelenkt ist. In dieser Ausgestaltung der Erfindung steht die Kolbenstange unmittelbar mit dem Scharnier in Verbindung.In a further embodiment of the invention it is provided that the damper is a running in a cylinder piston and a related to the piston Piston rod which is hinged to the hinge. In this embodiment of the invention, the piston rod is directly connected to the hinge in connection.

Weiterhin kann vorgesehen sein, dass die Kolbenstange nicht unmittelbar mit dem Scharnier in Verbindung steht, sondern dass ein Dämpferhebel vorgesehen ist, der mit der Kolbenstange sowie mit dem Scharnier schwenkbar in Verbindung steht.Furthermore, it can be provided that the piston rod is not directly in connection with the hinge, but that a damper lever is provided, which is pivotally connected to the piston rod and the hinge.

Der Dämpfer kann derart angeordnet sein, dass er unabhängig vom Öffnungswinkel der Tür oder Klappe in etwa parallel zur durch die Tür oder Klappe gebildeten oder zu der durch die Korpusfrontseite gebildeten Ebene verläuft.The damper may be arranged such that it runs approximately parallel to the door formed by the door or flap or to the plane formed by the body front side regardless of the opening angle of the door or flap.

In weiterer Ausgestaltung der Erfindung sind ein oder mehrere Rollen vorgesehen, die an dem Dämpferhebel angeordnet sind und die derart ausgeführt sind, dass sie quer zur Kolbenstange des Dämpfers wirkende Kräfte wenigstens beim Schließen der Tür oder Klappe aufnehmen. Denkbar ist, dass die quer zur Kolbenstange wirkenden Kräfte beim Schließen der Tür oder Klappe über die Rollreibung aufgenommen werden und beim Öffnen der Tür über ein oder mehrere Gleitelemente, die in einer oder mehreren Nuten laufen.In a further embodiment of the invention, one or more rollers are provided which are arranged on the damper lever and which are designed such that they absorb forces acting transversely to the piston rod of the damper at least when closing the door or flap. It is conceivable that the forces acting transversely to the piston rod are absorbed by the rolling friction when closing the door or flap, and when opening the door via one or more sliding elements which run in one or more grooves.

Dementsprechend kann vorgesehen sein, dass an dem Dämpferhebel unmittelbar oder mittelbar eine oder mehrere Gleitelemente angeordnet sind, die in einer oder in mehreren Nuten eines Trägers geführt sind. Möglich ist es, eine Ausführung sowohl mit einem oder mehreren Gleitelementen und mit einer oder mehreren Rollen vorzusehen. Denkbar ist es ebenfalls, auf die Rollen zu verzichten und sowohl beim Öffnen als auch beim Schließen Querkräfte ausschließlich über die Gleitelemente abzufangen.Accordingly, it can be provided that one or more sliding elements are arranged on the damper lever directly or indirectly, which are guided in one or more grooves of a carrier. It is possible to provide an embodiment with one or more sliding elements and with one or more rollers. It is also conceivable to dispense with the roles and intercept transverse forces only when opening and closing exclusively on the sliding elements.

Zum Zwecke der Veränderung des Dämpferhubes kann vorgesehen sein, dass ein oder mehrere Distanzstücke in die Nut einsetzbar ist, so dass die freie Nutlänge verändert wird.For the purpose of changing the damper stroke can be provided that one or more spacers can be inserted into the groove, so that the free groove length is changed.

Der Dämpferhebel kann mit der Kolbenstange derart lösbar verbunden sein, dass er über einen ersten Öffnungswinkel der Tür oder Klappe mit der Kolbenstange gekoppelt ist und dass er über einen zweiten Öffnungswinkel der Tür oder Klappe von der Kolbenstange entkoppelt ist. Auf diese Weise läßt sich eine Verkürzung des erforderlichen Dämpferweges erreichen.The damper lever may be releasably connected to the piston rod such that it is coupled to the piston rod via a first opening angle of the door or flap and that it is decoupled from the piston rod via a second opening angle of the door or flap. In this way, a shortening of the required Dämpferweges can be achieved.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass das Scharnier eine Kulissenführung aufweist, in der die Mittel, die eine auf den Exzenter wirkende Kraft ausüben, geführt sind. Durch Änderung der Kulissenführung läßt sich die Schließcharakteristik der Anordnung verändern.In a further embodiment of the invention it is provided that the hinge has a slotted guide, in which the means which exert a force acting on the eccentric, are guided. By changing the slotted guide, the closing characteristic of the arrangement can be changed.

Die Kulissenführung kann in einem der Hebel angeordnet sein.The slide guide can be arranged in one of the levers.

Die Mittel, die eine auf den Exzenter wirkende Kraft erzeugen, können um einen Anlenkpunkt schwenkbar angeordnet sein, der in seiner Position veränderbar ist. Auf diese Weise ist es möglich, die Türschließkraft bzw. das Schließverhalten der Tür zu verändern. Denkbar ist es, den Anlenkpunkt durch einen Exzenterbolzen zu bilden.The means which generate a force acting on the eccentric, can be pivotally mounted about a pivot point, which is variable in position. In this way it is possible to change the door closing force or the closing behavior of the door. It is conceivable to form the articulation point by an eccentric pin.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass der Dämpfer einen in einen Zylinder laufenden Kolben und eine mit dem Kolben in Verbindung stehende Kolbenstange aufweist und das zum Zwecke der Veränderung des Dämpfungsverhaltens die Lage des Kolbens in Bezug auf den Dämpferzylinder geändert wird. Diese Relativbewegung kann durch eine Änderung der Anlenkung/Anordnung des Dämpferzylinders an einem Träger oder dergleichen und/oder durch die Änderung der Anlenkung der Kolbenstange erzielt werden.In a further embodiment of the invention, it is provided that the damper has a running in a cylinder piston and a piston connected to the piston rod and the change in the damping behavior, the position of the piston is changed with respect to the damper cylinder. This relative movement can be achieved by changing the articulation / arrangement of the damper cylinder on a support or the like and / or by changing the articulation of the piston rod.

In weiterer Ausgestaltung der Erfindung ist ein Träger vorgesehen, in dem der Dämpfer angeordnet ist, wobei der Dämpfer beispielsweise mittels einer formschlüssigen Verbindung, vorzugsweise mittels einer Rastverbindung mit dem Träger in Verbindung steht. Auf diese Weise wird erreicht, dass die Montage des Dämpfers in dem Träger einfach ist und dass im Bedarfsfalle der Dämpfer ohne weiteres ausgetauscht werden kann.In a further embodiment of the invention, a carrier is provided, in which the damper is arranged, wherein the damper, for example, by means of a positive connection, preferably by means of a latching connection with the carrier is in communication. In this way it is achieved that the assembly of the Damper in the carrier is simple and that in case of need, the damper can be easily replaced.

Nach einem illustrativen, nicht von der Erfindung umfassten Beispiel ist es bevorzugt, wenn ein Modul vorgesehen ist, das einen Träger aufweist, in oder an dem der Dämpfer sowie das Scharnier angeordnet ist, wobei das Modul als Einheit in die Tür oder Klappe oder in den Korpus des Gerätes eingesetzt wird. Eine solche Modulbauweise ist besonders vorteilhaft, weil der Montageaufwand minimal ist und weil ein Türanschlagswechsel mit sehr geringem Aufwand durchführbar ist. Grundsätzlich kann auf eine solche modulare Bauweise auch verzichtet werden. Allerdings entstehen dann Nachteile beispielsweise beim Türanschlagwechsel, da dann die einzelnen Komponenten des erfindungsgemäßen Scharniers bzw. Dämpfers direkt in die Tür oder in den Korpus eingebaut werden müssen.According to an illustrative example, not embraced by the invention, it is preferred if a module is provided which has a carrier in or on which the damper and the hinge is arranged, wherein the module as a unit in the door or flap or in the Body of the device is used. Such a modular design is particularly advantageous because the assembly cost is minimal and because a Türanschlagwechsel can be carried out with very little effort. In principle, such a modular design can also be dispensed with. However, then disadvantages arise, for example, the door stop change, since then the individual components of the hinge or damper according to the invention must be installed directly into the door or in the body.

In weiterer Ausgestaltung des illustrativen Beispiels ist vorgesehen, dass das Scharnier und der Dämpfer und insbesondere das vorstehend beschriebene Modul außerhalb des gekühlten Bereiches des Gerätes angeordnet ist. Temperaturschwankungen sowie der Nachteil einer etwaigen Kondenswasserbildung werden auf diese Weise wirksam verhindert und die Lebensdauer von Scharnier und Dämpfer wird entsprechend verlängert.In a further embodiment of the illustrative example, it is provided that the hinge and the damper and in particular the module described above is arranged outside the cooled region of the device. Temperature fluctuations and the disadvantage of any condensation are effectively prevented in this way and the life of the hinge and damper is extended accordingly.

Denkbar ist es, das Scharnier sowie den Dämpfer beispielsweise in einem Bereich der Tür anzuordnen, der außerhalb des von der Türdichtung umgebenen Bereiches liegt. Dies kann im unteren Bereich oder auch im oberen Bereich der Tür sein. Entsprechendes gilt für eine Anordnung von Scharnier und Dämpfer am Korpus.It is conceivable, for example, to arrange the hinge and the damper in an area of the door which lies outside the area surrounded by the door seal. This can be in the lower area or in the upper area of the door. The same applies to an arrangement of hinge and damper on the body.

Der Dämpfer und insbesondere das Modul können in der zum Korpus gewandten Seite der Tür oder in der zur Tür gewandten Seite des Korpus angeordnet sein.The damper and in particular the module can be arranged in the side facing the carcass of the door or in the door facing side of the body.

Der Dämpfer und insbesondere das Modul können im Wesentlichen parallel zur durch die Tür gebildeten Ebene oder im Wesentlichen parallel zur durch die Frontseite des Korpus gebildeten Ebene angeordnet sein.The damper and in particular the module may be arranged substantially parallel to the plane formed by the door or substantially parallel to the plane formed by the front side of the body.

Das Modul kann durch eine formschlüssige Verbindung, insbesondere durch ein Rastverbindung, und/oder Schraubverbindung mit der Tür oder mit dem Korpus des Gerätes in Verbindung stehen. Denkbar ist beispielsweise, das durch Formschluß das Modul auf besonders einfache Art und Weise in der Tür oder in dem Korpus des Gerätes fixiert ist. Bei Bedarf kann eine Sicherung durch eine oder mehrere Schrauben erfolgen.The module can be connected by a positive connection, in particular by a latching connection, and / or screw connection with the door or with the body of the device. It is conceivable, for example, that the module is fixed by positive locking the module in a particularly simple manner in the door or in the body of the device. If necessary, a fuse can be made by one or more screws.

Die Erfindung betrifft des Weiteren ein Kühl- und/oder Gefriergerät mit einer Tür oder Klappe zum Verschließen des Geräteinnenraums, mit einem Scharnier, mittels dessen die Tür oder Klappe relativ zum Korpus des Gerätes verschwenkbar ist, wobei das Scharnier Mittel zum Erzeugen einer in Schließrichtung der Tür oder Klappe wirkenden Schließkraft aufweist, sowie mit einem Dämpfer, der wenigstens über einen Teil der Schließbewegung der Tür oder Klappe eine der Schließbewegung der Tür oder Klappe entgegengerichtete Kraft aufbringt, wobei die Mittel zum Erzeugen einer Schließkraft ein Zugseil umfassen, das einerseits mit dem Scharnier und andererseits mit einer oder mehreren Zugfedern in Verbindung steht, und wobei das Gerät gemäß dem kennzeichnenden Teil eines der Ansprüche 5, 7 bis 9 und 12 ausgeführt ist.The invention further relates to a refrigerator and / or freezer with a door or flap for closing the device interior, with a hinge by means of which the door or flap is pivotable relative to the body of the device, wherein the hinge means for generating a closing direction in the Having door or flap acting closing force, as well as with a damper which applies at least over a part of the closing movement of the door or flap one of the closing movement of the door or flap opposing force, wherein the means for generating a closing force comprise a pull rope, on the one hand with the hinge and, on the other hand, communicating with one or more tension springs, and wherein the device is designed according to the characterizing part of any one of claims 5, 7 to 9 and 12.

Der Kolben ist mit einer Kolbenstange 204 verbunden, deren Ende in Figur 1 ersichtlich ist. FIG. 1 shows in a sectional view of the body 20 of a refrigerator and the door 10 by means of which the device interior is closable. By the reference numeral 200, an oil / gas damper is characterized, which consists of a cylinder 202 in which a piston, not shown here runs. The piston is connected to a piston rod 204, whose end in FIG. 1 is apparent.

Gleiche Bezugszeichen in den Figuren kennzeichnen gleiche oder funktionsgleiche Bauteile, wobei aus Gründen der Übersichtlichkeit nicht in allen Figuren sämtliche Bezugszeichen verzeichnet sind.The same reference numerals in the figures denote the same or functionally identical components, for reasons of clarity not all the figures are listed in all figures.

Das den Korpus 20 mit der Tür 10 verbindende Scharnier besteht aus einem ersten Scharnierhebel 110 und einem zweiten Scharnierhebel 120. Beide Scharnierhebel sind um den Anlenkpunkt 111 relativ zueinander schwenkbar. Der erste Scharnierhebel 110 ist um die Achse 21 an dem Korpus 20 des Gerätes angelenkt und der zweite Scharnierhebel 120 ist um die Achse 11 an dem Träger 300 angelenkt, der formschlüssig und durch Schrauben gesichert in der Tür 10 des Gerätes aufgenommen ist.The hinge connecting the body 20 to the door 10 consists of a first hinge lever 110 and a second hinge lever 120. Both hinge levers are pivotable about the pivot point 111 relative to each other. The first hinge lever 110 is articulated about the axis 21 on the body 20 of the device and the second hinge lever 120 is articulated about the axis 11 on the carrier 300, which is positively received and secured by screws in the door 10 of the device.

An dem Scharnierhebel 120 ist der Exzenter 100 um die Achse 102 angelenkt. Der Exzenter 100 steht über einen Zughebel 130 mit dem ersten Scharnierhebel 110 in Verbindung. Der Zughebel 130 steht schwenkbar mit dem ersten Scharnierhebel 110 sowie mit dem Exzenter in Verbindung.On the hinge lever 120, the eccentric 100 is articulated about the axis 102. The eccentric 100 is connected via a pull lever 130 with the first hinge lever 110 in connection. The pull lever 130 is pivotally connected to the first hinge lever 110 and the eccentric in conjunction.

Mit dem zweiten Scharnierhebel 120 steht das Druckfederpaket in Verbindung, das aus einem Gehäuse 141 (s. Figur 1b) besteht, in dem zwei Druckfedern 140 angeordnet sind. In dem Gehäuse 141 ist verschieblich der Schlitten 142 aufgenommen, in dessen zu dem Exzenter 100 gerichteten Endbereich wenigstens eine Rolle 150 angeordnet ist, die auf der exzentrischen Oberfläche des Exzenters 100 läuft. Die Druckfedern üben auf den Schlitten 142 eine Kraft aus, die dazu führt, dass die Rolle 150 auf die Exzenteroberfläche gedrückt wird. Die Druckfederanlenkung befindet sich somit nicht an dem Dämpfer 200, sondern an dem Träger 300.Connected to the second hinge lever 120 is the compression spring assembly which consists of a housing 141 (see FIG. FIG. 1b ), in which two compression springs 140 are arranged. In the housing 141, the carriage 142 is slidably received, in its end region directed towards the eccentric 100 at least one roller 150 is arranged, which runs on the eccentric surface of the eccentric 100. The compression springs exert a force on the carriage 142 which causes the roller 150 to be pressed onto the eccentric surface. The Druckfederanlenkung is thus not on the damper 200, but on the carrier 300th

An den zweiten Scharnierhebel 120 ist der Dämpferhebel 155 angeordnet, der in seinem einen Endbereich an dem Anlenkpunkt 102 schwenkbar mit dem zweiten Scharnierhebel 120 in Verbindung steht und der mit seinem zweiten Endbereich mit zwei Rollen 160 versehen ist, die auf einer hier nicht näher dargestellten Führung des Trägers 300 laufen.At the second hinge lever 120 of the damper lever 155 is arranged, which is pivotally connected in its one end portion at the pivot point 102 to the second hinge lever 120 and which is provided with its second end portion with two rollers 160, which on a guide not shown here the carrier 300 run.

Die Figur 1b zeigt eine vergrößerte Darstellung der Scharnieranordnung gemäß Figur 1a.The FIG. 1b shows an enlarged view of the hinge assembly according to FIG. 1a ,

Wie dies aus den Figuren 1a und 1b hervorgeht, sind die Bestandteile des Scharniers, der Dämpfer 200 sowie der Dämpferhebel 155 bei geschlossener Tür im wesentlichen in die Tür integriert. Wie sich dies des Weiteren aus den Figuren 1a bis 1i ergibt, befindet sich der Dämpfer 200 in diesem Ausführungsbeispiel unabhängig vom Öffnungswinkel der Tür 10 stets in der Ebene der Tür.Like this from the FIGS. 1a and 1b As can be seen, the components of the hinge, the damper 200 and the damper lever 155 are integrated with the door closed substantially in the door. How is this further from the FIGS. 1a to 1i results, the damper 200 is in this embodiment, regardless of the opening angle of the door 10 always in the plane of the door.

Figur 1c, 1d zeigt die Anordnung bei einem Türöffnungswinkel von ca. 30°. Hieraus ist nochmals deutlich ersichtlich, dass der Zughebel 130 einerseits an dem Exzenter 100 und andererseits an dem ersten Scharnierhebel 110 angelenkt ist. Des weiteren ist ersichtlich, dass die Position der Rolle 150 relativ zur Oberfläche des Exzenters 100 sich mit dem Öffnen der Tür ändert, wie dies noch deutlicher aus den im folgenden erläuterten Figuren hervorgeht. Figure 1c . 1d shows the arrangement at a door opening angle of about 30 °. From this it is again clearly apparent that the pull lever 130 is articulated on the one hand to the eccentric 100 and on the other hand to the first hinge lever 110. Furthermore, it can be seen that the position of the roller 150 relative to the surface of the eccentric 100 changes with the opening of the door, as can be seen more clearly from the figures explained below.

Aus Figur 1c ist weiter ersichtlich, dass mit dem Öffnen der Tür die Kolbenstange 204 mit zunehmenden Öffnungswinkel weiter aus dem Zylinder 202 des Dämpfers 200 herausgezogen wird. Dementsprechend vollzieht sich der umgekehrte Vorgang, d. h. das Einschieben der Kolbenstange 204 in den Zylinder 202 und damit die Dämpfungswirkung beim Schließen der Tür.Out Figure 1c It can also be seen that with the opening of the door, the piston rod 204 is pulled further out of the cylinder 202 of the damper 200 with increasing opening angle. Accordingly, the reverse process, ie the insertion of the piston rod 204 in the cylinder 202 and thus the damping effect when closing the door takes place.

Figur 1d zeigt die Anordnung gemäß Figur 1c in einer vergrößerten Darstellung. Figure 1d shows the arrangement according to Figure 1c in an enlarged view.

Aus Figur 1e, 1f ergibt sich die Anordnung bei einem Türöffnungswinkel von 90°. In dieser Türstellung befindet sich die Rolle 150 in einem mittleren Bereich der Oberfläche des Exzenters 100. Die Konturierung der Oberfläche des Exzenters 100 ist derart ausgeführt, dass in dem hier dargestellten Ausführungsbeispiel ab einem Öffnungswinkel von ca. 55° durch die Druckfedern 140 kein eine Schließkraft hervorrufendes Drehmoment auf den Exzenter 100 ausgeübt wird. Dies bedeutet, dass die Tür in der Position stehen bleibt, in die sie der Nutzer des Gerätes bewegt hat.Out Figure 1e . 1f the arrangement results in a door opening angle of 90 °. In this door position, the roller 150 is located in a central region of the surface of the eccentric 100. The contouring of the surface of the eccentric 100 is designed such that in the embodiment shown here from an opening angle of about 55 ° by the compression springs 140 no closing force causing torque is exerted on the eccentric 100. This means that the door stops in the position in which it was moved by the user of the device.

Die Figuren 1g und 1h zeigt die Tür bei einem Öffnungswinkel von ca. 130° und die Figuren 1i und 1j zeigen die Tür bei einem Türöffnungswinkel von ca. 165°.The Figures 1g and 1h shows the door at an opening angle of about 130 ° and the Figures 1i and 1j show the door at a door opening angle of about 165 °.

Die in den Figuren 1a bis 1j dargestellte Anordnung ermöglicht die Realisierung eines Türschließverhaltens, bei dem in einem anfänglichen Winkelbereich, beispielsweise bei Öffnungswinkeln < 55°, eine Türschließung und in größeren Winkelbereichen eine Türverharrung erfolgt.The in the FIGS. 1a to 1j arrangement shown allows the realization of a door closing behavior, in which in an initial angular range, for example at opening angles <55 °, a door closure and in larger angular ranges a Türverharrung occurs.

Der Träger 300 kann mit den daran angeordneten Bauteilen ohne weiteres entnommen und beispielsweise bei einem Türanschlagswechsel an anderer Stelle wieder eingesetzt werden, ohne dass die Notwendigkeit besteht, die Bestandteile des Scharniers oder des Dämpfers einzeln zu demontieren und sodann wieder zu montieren.The carrier 300 can be easily removed with the components arranged thereon and reused in another place, for example during a door stop change, without the necessity of disassembling and then reinstalling the components of the hinge or the damper individually.

Der Träger 300 bzw. das Modul kann beispielsweise unten oder oben am Kühlgerät oder auch an einem auf mittlerer Höhe angeordneten Querträger montiert werden. Vorzugsweise wird der Träger bzw. das Modul derart angeordnet, dass sich keine Schwächung der Isolation ergibt. Dies läßt sich beispielsweise dadurch erreichen, dass der Dämpfer 200 mit diesem auch der Träger 300 quer, d.h. in der Ebene der Tür 10 oder in der durch die Korpusfront gebildeten ebene in Querrichtung eingesetzt wird.The carrier 300 or the module can be mounted, for example, at the bottom or at the top of the refrigerator or at a middle height arranged cross member. Preferably, the carrier or the module is arranged such that there is no weakening of the insulation. This can be achieved, for example, by virtue of the fact that the damper 200 with this also the carrier 300 transversely, i. is inserted in the plane of the door 10 or in the plane formed by the carcass front in the transverse direction.

Vorzugsweise wird der Träger 300 sowie der Dämpfer 200 horizontal in die Tür 10 oder in den Korpus 20 des Gerätes integriert.Preferably, the carrier 300 and the damper 200 are horizontally integrated in the door 10 or in the body 20 of the device.

Aufgrund der Flexibilität ist die erfindungsgemäße Anordnung vorteilhaft auch bei Doppeltürgeräten einsetzbar.Due to the flexibility of the arrangement according to the invention can also be used advantageously in double door devices.

Ein weiterer Vorteil der vorliegenden Erfindung besteht darin, dass der Dämpfer derart angeordnet werden kann, dass er geführt wird, so dass auch Stöße ohne weiteres aufgenommen werden können.Another advantage of the present invention is that the damper can be arranged so that it is guided, so that shocks can be easily absorbed.

Vorzugsweise ist das Scharnier derart ausgeführt, dass nur auf Zug oder Druck belastete Elemente des Scharniers existieren, d.h. es treten keine Drehmomente in den Gelenkarmen des Scharniers auf.Preferably, the hinge is designed such that only elements of the hinge loaded with tension or pressure exist, i. There are no torques in the articulated arms of the hinge.

Aus den Figuren 2a bis 2e ergeben sich perspektivische Darstellungen der erfindungsgemäßen Anordnung bei Öffnungswinkeln von 0°, 30 °, 90°, 130° und 165°. Aus dieser Darstellung wird ersichtlich, dass der Dämpfer in einem Träger 300 angeordnet ist, der als solches in die Tür 10 oder auch in den Korpus 20 des Gerätes eingesetzt wird.From the FIGS. 2a to 2e arise perspective views of the arrangement according to the invention at opening angles of 0 °, 30 °, 90 °, 130 ° and 165 °. From this representation, it can be seen that the damper is arranged in a carrier 300, which is inserted as such in the door 10 or in the body 20 of the device.

In dem Träger befindet sich eine Nut 302, in der Gleitelemente 170 laufen, die aus den Figuren 2a bis 2e ersichtlich sind. Wie auch die Rollen 160 sind die Gleitelemente 170 ebenfalls im Endbereich des Dämpferhebels 155 angeordnet und laufen beim Schließen und Öffnen der Tür in der Nut 302 des Trägers 300.In the carrier there is a groove 302, run in the sliding members 170, which consist of the FIGS. 2a to 2e can be seen. Like the rollers 160, the sliding elements 170 are likewise arranged in the end region of the damper lever 155 and run in the groove 302 of the carrier 300 when the door is closed and opened.

Die Figuren 3a bis 3e zeigen die erfindungsgemäße Anordnung in einer Draufsicht bei Öffnungswinkeln von 0°, 30 °, 90°, 130 und 165° und verdeutlichen nochmals die Anordnung des Gleitelementes 170 in der Nut 302 des Trägers 300.The FIGS. 3a to 3e show the arrangement according to the invention in a plan view at opening angles of 0 °, 30 °, 90 °, 130 and 165 ° and illustrate once again the arrangement of the sliding member 170 in the groove 302 of the carrier 300th

Figur 4 zeigt die Teile der erfindungsgemäßen Anordnung in einer Explosionsdarstellung. FIG. 4 shows the parts of the arrangement according to the invention in an exploded view.

Bei dem Träger kann es sich beispielsweise um ein Kunststoff umspritztes Metallteil handeln, das in einer entsprechenden Ausnehmung der Tür oder des Korpus verrastet und im Bedarfsfall verschraubt wird. Grundsätzlich ist eine ausschließlich formschlüssige Aufnahme anzustreben, da auf diese Weise der Träger 300 besonders einfach einsetzbar und bei Bedarf austauschbar bzw. ummontierbar ist.The carrier can be, for example, a plastic-encased metal part, which is locked in a corresponding recess of the door or the body and screwed if necessary. Basically, an exclusively positive fit is desirable, since in this way the carrier 300 is particularly easy to use and, if necessary, exchangeable or remountable.

Durch den Einsatz eines Trägers 300 lässt sich ein Optimum an Steifigkeit und Funktionen erzielen. Insbesondere können die auftretenden Kräfte des Dämpfers durch den Träger 300 aufgenommen werden. Es läßt sich darüber hinaus eine montageoptimierte Gestaltung und eine funktionsgerechte Werkstoffauswahl für die Gleitführung vornehmen.By using a carrier 300, an optimum of rigidity and functions can be achieved. In particular, the occurring forces of the damper can be absorbed by the carrier 300. It can be beyond a Assembly-optimized design and a functional material selection for the sliding guide.

Ein weiterer Vorteil des Dämpfers besteht darin, dass ein Zurückprellen der Tür beim Schließen mit großer Geschwindigkeit verhindert werden kann.Another advantage of the damper is that a rebound of the door when closing can be prevented with great speed.

Wird der Dämpfer linear geführt, wie dies bei dem Ausführungsbeispiel der Figuren 1a bis 1j der Fall ist, besteht neben dem Vorteil, dass der Dämpfer keine Querkräfte aufzunehmen hat, ein weiterer Vorteil darin, dass nahezu die gesamte Einheit abgedeckt werden kann, was eine erhöhte Sicherheit sowie Designvorteile bietet.If the damper is guided linearly, as in the embodiment of FIGS. 1a to 1j In addition to the advantage that the damper does not absorb any transverse forces, another advantage is that almost the entire unit can be covered, providing increased safety and design benefits.

Auch der Dämpfer 200 wird vorzugsweise in dem Träger 300 eingerastet, ohne das weitere Befestigungsmittel erforderlich sind.Also, the damper 200 is preferably locked in the carrier 300, without the further attachment means are required.

Ein wesentliches Merkmal der in den Figuren 1 bis 4 dargestellten Anordnung besteht darin, dass der Dämpfer 200 und damit auch die Kolbenstange 204 unabhängig vom Öffnungswinkel der Tür 10 stets in dem Träger 300 läuft, was den Vorteil mit sich bringt, dass der Dämpfer 200 besonders reibungsarm läuft, da etwaige Querkräfte nicht von auf den Dämpfer bzw. dessen Kolbenstange 204 einwirken.An essential feature of the FIGS. 1 to 4 The arrangement shown is that the damper 200 and thus the piston rod 204 regardless of the opening angle of the door 10 is always running in the carrier 300, which has the advantage that the damper 200 is running very low friction, since any lateral forces are not on the Damper or its piston rod 204 act.

Davon abweichend zeigen die Figuren 5a bis 5d eine Anordnung, bei der die Kolbenstange 204 nicht über einen Dämpferhebel, sondern unmittelbar mit dem Scharnier in Verbindung steht. Der Aufbau des Scharniers entspricht ansonsten dem in den Figuren 1 bis 4 gezeigten. Die Figuren 5a bis 5d zeigen die ebenfalls von der Erfindung umfaßte Anordnung bei einem Öffnungswinkel von 0°, 90°, 130° und 165°. Auch bei der in den Figuren 5a bis 5d gezeigten Anordnung ist ein Träger 300 vorgesehen, der in einer Ausnehmung der Tür aufgenommen ist. Um das Ausschwenken des Dämpfers 200 aus dem Träger 300 zu ermöglichen, ist der Dämpfer in dem Träger 300 schwenkbar angeordnet.Deviating show the FIGS. 5a to 5d an arrangement in which the piston rod 204 is not connected via a damper lever, but directly to the hinge. The structure of the hinge otherwise corresponds to that in the FIGS. 1 to 4 shown. The FIGS. 5a to 5d show the likewise encompassed by the invention arrangement at an opening angle of 0 °, 90 °, 130 ° and 165 °. Also in the in the FIGS. 5a to 5d As shown, a carrier 300 is provided, which is received in a recess of the door. In order to enable the swinging of the damper 200 from the carrier 300, the damper is pivotally mounted in the carrier 300.

Figur 6 zeigt eine Anordnung, bei der der Exzenter und die Druckfedern durch eine Seilzuganordnung ersetzt sind. Auch in diesem Fall schwenkt der Dämpfer 200 beim Öffnen der Tür aus der Tür aus, die Türschließfunktion wird jedoch über einen Seilzug 400 erzeugt, der in einem Endbereich mit einem der Scharnierhebel 110 und mit dem anderen Ende mit den Zugfedern 410, 420 in Verbindung steht. Der Seilzug 400 steht mit dem Scharnierhebel 110 in etwa an der Position in Verbindung, in der in den Ausführungen gemäß der Figuren 1 bis 4 die Zugstange 130 an dem Scharnierhebel 110 angelenkt ist. Figur 6a zeigt die Anordnung mit Dämpfer 200 und die Figuren 6b und 6c ohne Dämpfer. FIG. 6 shows an arrangement in which the eccentric and the compression springs are replaced by a cable arrangement. In this case as well, the damper 200 pivots out of the door when the door is opened, but the door closing function is generated by a cable 400 which is connected to one of the hinge levers 110 at one end portion and the tension springs 410, 420 at the other end , The cable 400 is connected to the hinge lever 110 in approximately the position in which in the embodiments according to the FIGS. 1 to 4 the pull rod 130 is hinged to the hinge lever 110. FIG. 6a shows the arrangement with damper 200 and the FIGS. 6b and 6c without damper.

Figur 7 zeigt die Nut 302 des Trägers 300. Aus dieser Figur ergibt sich, dass die Gleitelemente 170 in der Nut 302 laufen. Die Stützwirkung beim Schließen wird in der hier dargestellten Ausführungsform über die Rolle 160 erzeugt. Beim Öffnen bildet jedoch die obere Nutseite 303 die Anlage. Alternativ dazu ist es denkbar, auf die Rollen zu verzichten und die Anlage nicht nur beim Öffnen der Tür sondern auch beim Schließvorgang über die Gleitelemente 170 bzw. über die Nut 302 zu übernehmen. Das Bezugszeichen 304 kennzeichnet die dabei in Eingriff gelangende Anlage der Nut 302 über reine Gleitreibung. FIG. 7 shows the groove 302 of the carrier 300. From this figure it follows that the sliding elements 170 run in the groove 302. The support effect when closing is generated in the embodiment shown here via the roller 160. When opening, however, the upper groove side 303 forms the plant. Alternatively, it is conceivable to dispense with the roles and to take over the system not only when opening the door but also during the closing operation on the sliding elements 170 and via the groove 302. The reference numeral 304 indicates the engaging engagement of the groove 302 via pure sliding friction.

Figur 8 zeigt in vergrößerter Darstellung den Exzenter 100 sowie die Druckfederanordnung, mittels derer über die Rollen 150 auf die Oberfläche des Exzenters 100 eine Druckkraft ausgeübt wird. Durch ein mögliches Ersetzen der beiden Druckfedern durch andere Federn mit anderen Kennwerten kann die Federkraft und somit auch die Türschließkraft verändert werden. Eine weitere Möglichkeit, die Türschließkraft zu beeinflussen besteht darin, dass der Anlenkpunkt des hier dargestellten Gehäuses 141, das die Federn 140 aufnimmt, mittels eines Exzenterbolzens 190 erfolgt, was zur Folge hat, dass so die Federkraft und des weiteren auch die Federwirklinie verändert werden kann. Das Bezugszeichen 148 kennzeichnet die Federkennlinie ohne Verstellung und das Bezugszeichen 149 die Federkennlinie nach der Verstellung des Anlenkpunktes des Gehäuses 141. FIG. 8 shows an enlarged view of the eccentric 100 and the compression spring arrangement, by means of which on the rollers 150 on the surface of the eccentric 100, a compressive force is exerted. By a possible replacement of the two compression springs by other springs with other characteristics, the spring force and thus the door closing force can be changed. Another way to influence the door closing force is that the articulation point of the housing 141 shown here, which receives the springs 140, done by means of an eccentric pin 190, with the result that so the spring force and the other also the spring line can be changed , The reference numeral 148 denotes the spring characteristic without adjustment and the reference numeral 149 the spring characteristic after the adjustment of the articulation point of the housing 141.

Eine Änderung der Türschließcharakteristik kann auch dadurch bewirkt werden, dass die Exzenterbahn, d.h. die Oberfläche des Exzenters 100 in Zusammenspiel mit einer ebenfalls veränderten Nockenbahn beeinflußt wird, wie dies aus Figur 9 hervorgeht. In dieser Figur kennzeichnet das Bezugszeichen 100' die Exzenterbahn und das Bezugszeichen 150' die Nockenbahn.A change in the door closing characteristic can also be effected by influencing the eccentric track, ie the surface of the eccentric 100 in cooperation with a likewise changed cam track, as is known FIG. 9 evident. In this figure, reference numeral 100 'denotes the cam track and reference numeral 150' the cam track.

Figur 10 verdeutlicht, dass durch ein Verschieben des Zylinders 202 des Dämpfers 200 relativ zur Kolbenstange 204 und somit auch relativ zu dem Kolben eine wesentliche Veränderung des Dämpfverhaltens bewirkt werden kann. Dabei erfolgt eine Veränderung der Lage der Überströmkanäle 203 relativ zu dem mit der Kolbenstange verbundenen Kolben. Diese Relativbewegung kann, wie dies aus Figur 10 hervorgeht, entweder über ein stufenlose Verstellmöglichkeit des Zylinders 202, d.h. der der Dämpferanlenkung geschehen, wie dies durch den links dargestellten Doppelpfeil angedeutet ist, oder über eine kolbenstangenseitige Relativlageveränderung der Kolbenstangenanlenkung, wie dies durch den rechts dargestellten Doppelpfeil angedeutet ist. FIG. 10 illustrates that by shifting the cylinder 202 of the damper 200 relative to the piston rod 204 and thus also relative to the piston, a significant change in the damping behavior can be effected. In this case, there is a change in the position of the overflow channels 203 relative to the piston connected to the piston rod. This relative movement can, as is out FIG. 10 shows, either via a stepless adjustment of the cylinder 202, that is done the Dämpferanlenkung, as indicated by the double arrow shown on the left, or a piston rod side Relativlageveränderung the Kolbenstangenanlenkung, as indicated by the double arrow shown on the right.

Selbstverständlich ist eine Änderung der Dämpfungscharakteristik auch durch Austausch des Dämpfers 200 realisierbar.Of course, a change in the damping characteristic can also be realized by replacing the damper 200.

Figur 11 verdeutlich schließlich, dass die Dämpferhubbegrenzung über das Anschlagen des oder der Gleitstücke 170 am Nutende 302' erfolgt. Durch Einsetzen von hier nicht dargestellten Distanzstücken in die Nut 302 des Trägers 300 kann auf einfache Art und Weise die freie Nutlänge verändert werden kann. Auf diese Weise ist es möglich, eine gewünschte begrenzte Zwischentüröffnungslage zu erzeugen. Es ist auch denkbar, diese Begrenzung des Gleitträgerweges stufenlos über entsprechende Mechanismen, wie beispielsweise ein Zugseil zu erzeugen. FIG. 11 finally clarifies that the Dämpferhubbegrenzung via the striking of the slider or 170 at the Nutende 302 'takes place. By inserting spacers, not shown here, into the groove 302 of the carrier 300, the free groove length can be changed in a simple manner. In this way it is possible to produce a desired limited intermediate door opening position. It is also conceivable to produce this limitation of Gleitträgerweges continuously via appropriate mechanisms, such as a pull rope.

Eine weitere Ausgestaltung der Erfindung ist in Figur 12 angedeutet. Hier dargestellt ist der Dämpferhebel 155, der wie oben ausgeführt, die Rolle 160 bzw. das Gleitstück 170 mit dem Scharnierhebel 120 verbindet. Diese Dämpfungscharakteristik basiert darauf, dass der Dämpfer 200 über den kompletten Türöffnungswinkel niemals außer Eingriff kommt. Daraus ergibt sich der Vorteil, dass unangenehme Stoßerscheinungen, die weder für den Nutzer noch für das Material wünschenswert sind, grundsätzlich vermieden werden. Allerdings ist es auch denkbar, den Dämpferhebel 155 in den Gleitträger 170 in einen definierten Türöffnungswinkelbereich ein- und auszukoppeln. Dadurch läßt sich eine Verkürzung des erforderlichen Dämpferweges erreichen. Um mögliche Stöße zu vermeiden, sollte dieser ausgekoppelte Zustand in einem Öffnungsbereich liegen, der ohnehin nur mit wenig Dämpfung stattfindet.A further embodiment of the invention is in FIG. 12 indicated. Shown here is the damper lever 155, which, as stated above, the roller 160 and the slider 170 connects to the hinge lever 120. These Damping characteristics based on the fact that the damper 200 never disengages over the entire door opening angle. This results in the advantage that unpleasant impact phenomena, which are neither desirable for the user nor for the material, are fundamentally avoided. However, it is also conceivable for the damper lever 155 to be coupled into and out of the slide carrier 170 in a defined door opening angle range. As a result, a shortening of the required Dämpferweges can be achieved. To avoid possible shocks, this decoupled state should be in an opening area, which takes place anyway only with little attenuation.
