Description

Die vorliegende Erfindung betrifft ein Scharnier nach dem Oberbegriff des Anspruches 1.The present invention relates to a hinge according to the preamble of claim 1.

Die EP 2 176 486 offenbart ein Scharnier, bei dem ein Scharnierteil verschwenkbar an einem Seitenteil gelagert ist, in dem ein Lineardämpfer angeordnet ist. Bei einer Schließbewegung des Scharnierteils wird der als Druckdämpfer ausgebildete Lineardämpfer zusammengedrückt und bremst die Schließbewegung ab, um ein Anschlagen der Tür zu vermeiden. Ein solches Scharnier hat sich an sich in der Praxis bewährt und wird gerne in unterschiedlichen Möbeln verbaut. Bei einer Öffnungsbewegung der Tür kann allerdings ein Abbremsen an einem Anschlag für eine erhebliche Materialbelastung sorgen.The EP 2 176 486 discloses a hinge in which a hinge part is pivotally mounted on a side part in which a linear damper is arranged. During a closing movement of the hinge part, the linear damper designed as a pressure damper is compressed and slows down the closing movement in order to prevent the door from being hit. Such a hinge has proven itself in practice and is often installed in different furniture. During an opening movement of the door, however, braking on a stop can ensure a considerable material load.

Die DE 20 2012 012 211 U1 offenbart ein Scharnier mit einem Gelenkhebelmechanismus, der über einen Koppelhebel mit einem Lineardämpfer verbunden ist. Das Scharnier kann über den Gelenkhebelmechanismus sowohl in Schließ- als auch in Öffnungsrichtung gedämpft werden.The DE 20 2012 012 211 U1 discloses a hinge with a toggle mechanism which is connected via a coupling lever with a linear damper. The hinge can be damped via the toggle mechanism both in the closing and in the opening direction.

Es ist daher Aufgabe der vorliegenden Erfindung, ein Scharnier zu schaffen, das eine verbesserte Handhabung gewährleistet.It is therefore an object of the present invention to provide a hinge which ensures improved handling.

Diese Aufgabe wird mit einem Scharnier mit den Merkmalen des Anspruches 1 gelöst.This object is achieved by a hinge with the features of claim 1.

Erfindungsgemäß weist das Scharnier ein zwischen dem Führungshebel und dem Lineardämpfer angeordnetes Umlenkelement auf, das bei einer Schließbewegung des Scharnierteils den Dämpfer zur Erzeugung einer Dämpfungskraft bewegt und zudem bei einer Öffnungsbewegung des Scharnierteils vor Erreichen der maximalen Öffnungsposition des Scharnierteils den Dämpfer zur Erzeugung einer Dämpfungskraft bewegt. Der Lineardämpfer wird über das Umlenkelement so betätigt, dass sowohl eine Dämpfungskraft bei einer Schließbewegung des Scharnierteils vor Erreichen der Schließposition als auch eine Dämpfungskraft bei einer Öffnungsbewegung des Scharnierteils kurz vor Erreichen der maximalen Öffnungsposition erzeugt wird. Dadurch kann der Lineardämpfer sowohl für eine Schließdämpfung als auch eine Öffnungsdämpfung eingesetzt werden. Bei einer Öffnungsbewegung des Scharniers wird somit ein Anschlagen bei Erreichen der maximalen Öffnungsposition vermieden, da die Öffnungsbewegung kurz vor der Öffnungsposition durch den Lineardämpfer abgebremst wird. Dies verringert die Materialbelastung bei einer schnellen Öffnungsbewegung, da ein abruptes Abbremsen in der maximalen Öffnungsposition vermieden wird.According to the invention, the hinge has a deflection element arranged between the guide lever and the linear damper, which moves the damper to produce a damping force during a closing movement of the hinge part and also moves the damper to generate a damping force during an opening movement of the hinge part before reaching the maximum opening position of the hinge part. The linear damper is actuated via the deflecting element so that both a damping force during a closing movement of the hinge part before reaching the closing position and a damping force during an opening movement of the hinge part is generated shortly before reaching the maximum opening position. This allows the linear damper both for a closing damping and an opening damping be used. In an opening movement of the hinge thus a striking is avoided upon reaching the maximum opening position, since the opening movement is slowed down shortly before the opening position by the linear damper. This reduces the material load during a fast opening movement, since an abrupt braking in the maximum open position is avoided.

Gemäß der Erfindung ist die Öffnungsdämpfung zumindest in einem Winkelbereich von mindestens 10°, insbesondere mindestens 20°, vor der maximalen Öffnungsposition des Scharnierteils wirksam. Abhängig von der maximalen Öffnungsposition des Scharnierteils, die beispielsweise bei 90°, 100° oder 110° angeordnet sein kann, kann der Beginn der Öffnungsdämpfung gewählt werden. Zumindest eine Dämpfung über einen Winkelbereich von mehr als 20° kann ein ausreichendes Abbremsen in Öffnungsrichtung durch den Lineardämpfer gewährleisten.According to the invention, the opening damping is effective at least in an angular range of at least 10 °, in particular at least 20 °, before the maximum opening position of the hinge part. Depending on the maximum opening position of the hinge part, which may be arranged, for example, at 90 °, 100 ° or 110 °, the beginning of the opening damping can be selected. At least damping over an angular range of more than 20 ° can ensure sufficient deceleration in the opening direction by the linear damper.

Vorzugsweise ist die Richtung der Relativbewegung zwischen Kolbenstange und Dämpfergehäuse bei einem Schließvorgang des Scharniers im Schließdämpfungsbereich des Scharniers gleich der Richtung wie beim Öffnungsvorgang des Scharniers im Öffnungsdämpfungsbereich. Unter der Relativbewegung ist eine Bewegung zwischen dem Kolben und dem Dämpfergehäuse zu verstehen, unabhängig davon welcher der beiden Körper tatsächlich bewegt wird. Es ist auch möglich das sich beide Körper gleichzeitig bewegen. Wird ein Druckdämpfer eingesetzt, der beim Einschieben der Kolbenstange in das Dämpfergehäuse eine Dämpfungskraft erzeugt, wird daher vorzugsweise sowohl bei der Schließdämpfung als auch bei der Öffnungsdämpfung die Kolbenstange in das Dämpfergehäuse eingeschoben. Umgekehrt würde bei Einsatz eines Zugdämpfers die Kolbenstange im Dämpfungsbereich jeweils aus dem Dämpfergehäuse herausgezogen, sowohl bei der Öffnungsdämpfung als auch bei der Schließdämpfung.Preferably, the direction of the relative movement between the piston rod and the damper housing during a closing operation of the hinge in the Schließdämpfungsbereich of the hinge is equal to the direction as in the opening operation of the hinge in the opening damping area. The relative movement is a movement between the piston and the damper housing to understand, regardless of which of the two bodies is actually moved. It is also possible that both bodies move at the same time. If a pressure damper is used which generates a damping force when the piston rod is pushed into the damper housing, the piston rod is therefore preferably inserted into the damper housing both in the case of the closing damping and in the case of the opening damping. Conversely, when using a Zugdämpfers the piston rod in the damping region in each case pulled out of the damper housing, both in the opening damping and in the closing damping.

Vorzugsweise führt das an einer Achse gelagerte Umlenkelement bei einer Bewegung von der vollständig geschlossenen Position des Scharnierteils in die vollständig geöffnete Position des Scharnierteils eine Pendelbewegung aus. Mit Pendelbewegung ist dabei eine Bewegung gemeint, die zunächst in eine Richtung eine Drehbewegung und dann eine Drehbewegung in die gegenüberliegende Richtung beinhaltet. Die Bewegungsrichtung der Pendelbewegung des Umlenkelementes kehrt sich dabei von einer Bewegung von einer vollständig geschlossenen Position des Scharnierteils in die vollständig geöffnete Position des Scharnierteils zwischen dem Schließdämpfungsbereich und dem Öffnungsdämpfungsbereichs um. Dies ermöglicht den Einsatz eines einzigen Lineardämpfers, um sowohl eine Öffnungs- als auch Schließdämpfung bereitzustellen.Preferably, the deflecting element mounted on an axle performs a pendulum motion upon movement from the fully closed position of the hinge member to the fully open position of the hinge member. By pendulum motion is meant a movement that includes first in one direction a rotational movement and then a rotational movement in the opposite direction. The direction of movement of the pendulum movement of the deflecting element is reversed by a movement from a fully closed position of the hinge part in the fully open position the hinge part between the Schließdämpfungsbereich and the opening damping area to. This allows the use of a single linear damper to provide both opening and closing damping.

Vorzugsweise ist der Hub des Lineardämpfers bei einer Schließdämpfung größer als der Hub des Lineardämpfers bei einer Öffnungsdämpfung. Bei gleicher Drehgeschwindigkeit des Scharnierteils relativ zu dem Seitenteil sind somit die Dämpfungskräfte beim Schließen größer als beim Öffnen. Meist wird beim Öffnen der Tür diese ohnehin leicht abgebremst, so dass kleinere Dämpfungskräfte gewählt werden können, die für den Benutzer weniger als störend empfunden werden, wenn dieser gegen die Dämpfungskräfte die Tür bewegt.Preferably, the stroke of the linear damper at a closing loss is greater than the stroke of the linear damper at an opening loss. At the same rotational speed of the hinge part relative to the side part thus the damping forces are greater when closing than when opening. Usually when opening the door this is easily braked, so that smaller damping forces can be selected, which are less disturbing for the user when it moves against the damping forces the door.

Der Dämpfer ist vorzugsweise als Druckdämpfer ausgebildet, bei dem beim Einschieben der Kolbenstange in das Dämpfergehäuse höhere Dämpfungskräfte erzeugt werden als beim Herausziehen der Kolbenstange aus dem Dämpfergehäuse. Dadurch kann eine besonders kompakte Bauweise erhalten werden, da Druckdämpfer in kurzer Bauweise eingesetzt werden können.
In einer anderen Ausgestaltung ist der Dämpfer vorzugsweise als Zugdämpfer ausgebildet, bei dem beim Ausziehen der Kolbenstange aus dem Dämpfergehäuse höhere Dämpfungskräfte erzeugt werden als beim Einschieben der Kolbenstange in das Dämpfergehäuse.The damper is preferably designed as a pressure damper, in which higher damping forces are generated during insertion of the piston rod into the damper housing than when pulling out the piston rod from the damper housing. As a result, a particularly compact construction can be obtained since pressure dampers can be used in a short design.
In another embodiment, the damper is preferably designed as a tensile damper, in which when pulling the piston rod from the damper housing higher damping forces are generated than when inserting the piston rod in the damper housing.

Vorzugweise ist die Feder die das Scharnier in einem Selbsteinzugsbereich des Scharniers in die geschlossene Position vorspannt auch als Öffnungsfeder ausgebildet, die das Scharnierteil ab einem Öffnungswinkel des Scharniers in die vollständig geöffnete Position bewegt. In einer anderen Ausgestaltung kann diese Funktion auch von wenigstens einer separaten Öffnungsfeder übernommen werden, so dass eine Schließfeder und eine Öffnungsfeder vorgesehen sind.Preferably, the spring which biases the hinge in a self-retraction area of the hinge to the closed position is also designed as an opening spring which moves the hinge part from an opening angle of the hinge into the fully open position. In another embodiment, this function can also be taken over by at least one separate opening spring, so that a closing spring and an opening spring are provided.

Ein Möbel 1 umfasst einen schrankförmigen Möbelkorpus 2, an dessen Seitenwand zwei Scharniere 4 zur verschwenkbaren Lagerung einer Tür 3 vorgesehen sind. Jedes Scharnier 4 umfasst dabei eine Montageplatte 6, die an einer Seitenwand des Möbelkorpus 2 festgelegt ist, wobei ein Seitenteil 5 des Scharniers 4 an der Montageplatte 6 gehalten ist. An dem Seitenteil 5 ist ein Scharnierteil 7 über eine Vier-Gelenkverbindung verschwenkbar gelagert.A piece of furniture 1 comprises a cabinet-shaped furniture body 2, on whose side wall two hinges 4 are provided for the pivotable mounting of a door 3. Each hinge 4 comprises a mounting plate 6 which is fixed to a side wall of the furniture body 2, wherein a side part 5 of the hinge 4 is held on the mounting plate 6. On the side part 5, a hinge part 7 is pivotally mounted via a four-joint connection.

In Figur 2 ist das Scharnier 4 im Detail gezeigt. Das Scharnier 4 umfasst die am Möbelkorpus festlegbare Montageplatte 6, an der ein Innenteil 26 festgelegt ist, das wiederum zur Fixierung des Seitenteils 5 dient. Das Seitenteil 5 ist über ein erstes Verstellelement 24 und ein zweites Verstellelement 25 relativ zu der Montageplatte 6 und dem Innenteil 26 bewegbar, um die Position der Tür 3 relativ zu dem Möbelkorpus 2 ausrichten zu können.In FIG. 2 the hinge 4 is shown in detail. The hinge 4 comprises the furniture body fixable mounting plate 6, on which an inner part 26 is fixed, which in turn serves to fix the side part 5. The side part 5 is movable relative to the mounting plate 6 and the inner part 26 via a first adjusting element 24 and a second adjusting element 25 in order to be able to align the position of the door 3 relative to the furniture body 2.

Das Seitenteil 5 ist kastenförmig ausgebildet und umfasst an gegenüberliegenden Seitenwänden Öffnungen 21, 22 und 23, die zur Lagerung von Achsen 20 dienen.The side part 5 is box-shaped and comprises on opposite side walls openings 21, 22 and 23, which serve to support axes 20.

Das Scharnierteil 7 umfasst eine topfförmige Aufnahme 10, wobei an Seitenwänden der topfförmigen Aufnahme 10 Öffnungen 11 und 12 für Achselemente 13 ausgebildet sind. Die Achselemente 13 sind U-förmig ausgebildet und weisen einen längeren Schenkel auf, der als Drehachse für einen Traghebel 8 oder einen Führungshebel 9 dient. Der Traghebel 8 ist dabei um die in die Öffnung 11 gesteckte Achse und der Führungshebel 9 ist um die in die Öffnung 12 gesteckte Achse drehbar am Scharnierteil 7 gelagert.The hinge part 7 comprises a cup-shaped receptacle 10, wherein on side walls of the cup-shaped receptacle 10 openings 11 and 12 are formed for axle elements 13. The shaft elements 13 are U-shaped and have a longer leg, which serves as a rotation axis for a support lever 8 or a guide lever 9. The support lever 8 is about the inserted into the opening 11 axis and the guide lever 9 is rotatably mounted on the inserted into the opening 12 axis on the hinge part 7.

Zwischen dem Traghebel 8 und dem Führungshebel 9 ist noch eine Feder 14 angeordnet, die zwei hervorstehende Schenkel aufweist und als Anzugsfeder ausgebildet ist. Über die Feder 14 wird das Scharnierteil 7 in einem Selbsteinzugsbereich des Scharniers 4 in die geschlossene Position vorgespannt.Between the support lever 8 and the guide lever 9, a spring 14 is still arranged, which has two protruding legs and is designed as a suit spring. Via the spring 14, the hinge part 7 is biased in a self-retraction region of the hinge 4 in the closed position.

Der Traghebel 8 ist an dem Seitenteil 5 über eine Achse 20 drehbar gelagert, die in die Öffnung 21 eingesteckt ist, während der Führungshebel 9 an dem Seitenteil 5 drehbar gelagert ist um eine Achse 20, die in die Öffnung 22 eingesteckt ist. Beabstandet von den Achsen an den Öffnungen 21 und 22 ist eine Achse 16 in die Öffnung 23 eingesteckt, um ein Umlenkelement 15 um eine Achse 16 drehbar zu lagern. Das Umlenkelement 15 ist als zweiarmiger Hebel ausgebildet, wobei an einem ersten Hebelarm eine Achse 17 zur gelenkigen Verbindung mit einem Hebel 19 vorgesehen ist. Dieser ist einerseits mit dem Umlenkelement 15 und andererseits mit einem Ausleger an dem Führungshebel 9 gelenkig verbunden ist. Das Umlenkelement 15 besitzt einen zweiten Arm, an dem eine Achse 18 vorgesehen ist, um das Umlenkelement 15 gelenkig mit einem Dämpfer 30 zu verbinden, der als Lineardämpfer ausgebildet ist. Der Dämpfer 30 umfasst eine Kolbenstange 31 und ein Dämpfergehäuse 32, in dem ein Kolben angeordnet ist. Durch Einschieben und Herausziehen der Kolbenstange 31 wird der Kolben innerhalb des Dämpfergehäuses 32 bewegt, wobei beim Einschieben der Kolbenstange 31 Dämpfungskräfte erzeugt werden, während das Herausziehen der Kolbenstange 31 vergleichsweise leichtgängig erfolgt. Der Dämpfer ist somit als Druckdämpfer ausgebildet, der im Wesentlichen nur beim Einschieben der Kolbenstange 31 Dämpfungskräfte erzeugt. Die Kolbenstange 31 ist dabei am äußeren Ende mit einem Verbindungselement 34 versehen, das gelenkig mit dem zweiten Arm mit der Achse 18 des Umlenkelementes 15 verbunden ist. Auf der gegenüberliegenden Seite ist das Dämpfergehäuse 32 mit einem Halter 33 ausgestattet, um den Dämpfer 30 gelenkig in dem Seitenteil 5 zu lagern.The support lever 8 is rotatably mounted on the side part 5 via an axis 20 which is inserted into the opening 21, while the guide lever 9 is rotatably mounted on the side part 5 about an axis 20 which is inserted into the opening 22. Spaced from the axes at the openings 21 and 22, an axis 16 is inserted into the opening 23 to rotatably support a deflecting element 15 about an axis 16. The deflecting element 15 is designed as a two-armed lever, wherein an axis 17 is provided for articulated connection with a lever 19 on a first lever arm. This is on the one hand articulated to the deflecting element 15 and on the other hand with a boom on the guide lever 9. The deflecting element 15 has a second arm on which an axle 18 is provided to connect the deflecting element 15 articulated to a damper 30, which is designed as a linear damper. The damper 30 includes a piston rod 31 and a damper housing 32 in which a piston is disposed. By inserting and pulling out the piston rod 31, the piston is moved within the damper housing 32, 31 damping forces are generated during insertion of the piston rod, while the extraction of the piston rod 31 is relatively smooth. The damper is thus designed as a pressure damper, which generates 31 damping forces substantially only when inserting the piston rod. The piston rod 31 is provided at the outer end with a connecting element 34 which is pivotally connected to the second arm with the axis 18 of the deflecting element 15. On the opposite side, the damper housing 32 is provided with a holder 33 for supporting the damper 30 in the side part 5 in an articulated manner.

Um das Seitenteil 5 an der Montageplatte zu fixieren, ist ferner noch eine verschwenkbare Rasteinrichtung 27 vorgesehen.In order to fix the side part 5 on the mounting plate, a pivotable locking device 27 is also still provided.

In Figur 3 ist das Scharnier 4 in einer Schließstellung gezeigt, bei der die Tür 3 in einer geschlossenen Position gehalten ist. Das Scharnier 4 ist dabei nur schematisch gezeigt, da es bei der Erläuterung der Öffnungs- und Schließbewegung im Wesentlichen auf die Position des Scharnierteils 7 und die damit verbundene Bewegung des Dämpfers 30 ankommt. In der Schließposition ist der Dämpfer 30 in der eingefahrenen Position, in der die Kolbenstange 31 weitgehend in das Dämpfergehäuse 32 eingeschoben ist. Wird das Scharnier 4 nun geöffnet (Figur 4), verschwenkt das Scharnierteil 7 entsprechend der Vier-Gelenkverbindung über den Traghebel 8 und den Führungshebel 9, wobei der schematisch dargestellte Hebel 19 das Umlenkelement 15 im Uhrzeigersinn um die Achse 16 dreht. Dadurch wird die Kolbenstange 31 geringfügig aus dem Dämpfergehäuse 32 herausgezogen, wobei das Herausziehen der Kolbenstange 31 leichtgängig erfolgt, so dass kaum eine Bremswirkung beim Öffnen zu spüren ist. Das Scharnierteil kann zusammen mit der Tür 3 entsprechend Figur 5 weiter in Öffnungsrichtung bewegt werden, wobei durch die oben beschriebene Mechanik die Kolbenstange 31 noch weiter aus dem Dämpfergehäuse 32 herausgezogen wird.In FIG. 3 the hinge 4 is shown in a closed position, in which the door 3 is held in a closed position. The hinge 4 is shown only schematically, since it essentially in the explanation of the opening and closing movement on the position of the hinge part 7 and the associated movement of the damper 30 arrives. In the closed position, the damper 30 is in the retracted position, in which the piston rod 31 is largely inserted into the damper housing 32. If the hinge 4 is now opened ( FIG. 4 ), pivots the hinge part 7 corresponding to the four-joint connection via the support lever 8 and the guide lever 9, wherein the lever 19 shown schematically rotates the deflector 15 in a clockwise direction about the axis 16. As a result, the piston rod 31 is slightly pulled out of the damper housing 32, wherein the withdrawal of the piston rod 31 is smooth, so that hardly a braking effect is felt when opening. The hinge part can be used together with the door 3 accordingly FIG. 5 be moved further in the opening direction, wherein the piston rod 31 is further pulled out of the damper housing 32 by the mechanism described above.

Wird die Tür 3 zwischen der in Figur 5 und Figur 6 gezeigten Position weiter in Öffnungsrichtung bewegt, wird die Kolbenstange 31 kaum noch relativ zu dem Dämpfergehäuse 32 bewegt, so dass die Öffnungsbewegung leichtgängig erfolgen kann.Will the door 3 between the in FIG. 5 and FIG. 6 shown moved further in the opening direction, the piston rod 31 is hardly moved relative to the damper housing 32, so that the opening movement can be smoothly.

Wird die Tür 3 nun in die maximale Öffnungsstellung verschwenkt, wie dies in Figur 7 gezeigt ist, bewirkt das Verschwenken des Traghebels 8 und des Führungshebels 9 ein Verschwenken des Umlenkelementes 15 gegen den Uhrzeigersinn, so dass die Kolbenstange 31 wieder in das Dämpfergehäuse 32 eingeschoben wird. Beim Einschieben der Kolbenstange 31 in das Dämpfergehäuse 32 werden Dämpfungskräfte erzeugt, die für ein Abbremsen der Öffnungsbewegung der Tür 3 sorgen.If the door 3 is now pivoted to the maximum open position, as in FIG. 7 is shown, the pivoting of the support lever 8 and the guide lever 9 causes a pivoting of the deflecting element 15 counterclockwise, so that the piston rod 31 is pushed back into the damper housing 32. When inserting the piston rod 31 in the damper housing 32 damping forces are generated, which ensure a slowing down the opening movement of the door 3.

Wird die Tür 3 nun aus der maximalen Öffnungsposition wieder in Schließrichtung bewegt, wird die Kolbenstange 31 zunächst wieder aus dem Dämpfergehäuse 32 herausgezogen, wobei das Herausziehen der Kolbenstange 31 leichtgängig erfolgt, so dass kaum Kräfte durch den Benutzer zu spüren sind. Anschließend werden die Positionen gemäß den Figuren 6, 5, 4, durchlaufen, wobei ab einem bestimmten Winkelbereich die Kolbenstange 31 wieder in das Dämpfergehäuse 32 eingeschoben wird, wie dies in den Figuren 4 und 3 gezeigt ist. Dadurch setzt eine Schließdämpfung ein, indem der Dämpfer 30 vor Erreichen der Schließposition Dämpfungskräfte erzeugt.If the door 3 is now moved from the maximum opening position back in the closing direction, the piston rod 31 is first pulled out of the damper housing 32, wherein the withdrawal of the piston rod 31 is smooth, so that hardly any forces are felt by the user. Subsequently, the positions in accordance with the FIGS. 6 . 5 . 4 , go through, being from a certain angle range, the piston rod 31 is pushed back into the damper housing 32, as shown in the FIGS. 4 and 3 is shown. As a result, a closing damping sets in by the damper 30 generates damping forces before reaching the closed position.

In Figur 8 ist der Bereich der Schließdämpfung α und der Öffnungsdämpfung β schematisch dargestellt. Beim Verschwenken des Scharnierteils 7 relativ zu dem Seitenteil 5 kann in einem Winkelbereich α vor Erreichen der Schließposition, beispielsweise in einem Bereich zwischen 0° und 30°, eine Schließdämpfung über den Dämpfer 30 bewirkt werden. Ferner wird vor Erreichen einer maximalen Öffnungsposition in einem Winkelbereich β eine Öffnungsdämpfung über den Dämpfer 30 bewirkt. Die Öffnungsdämpfung kann beispielsweise in einem Bereich von mindestens 10°, insbesondere mindestens 20°, vor Erreichen der maximalen Öffnungsposition bewirkt werden. Die maximale Öffnungsposition kann je nach Scharniertyp 80° bis 120° betragen. In einem mittleren Bereich zwischen der Schließdämpfung α und der Öffnungsdämpfung β ist der Dämpfer 30 im Wesentlichen wirkungslos, um ein Öffnen oder Schließen der Tür 3 nicht zu behindern. Der mittlere Bereich, in dem der Dämpfer 30 unwirksam ist, kann beispielsweise zwischen 45° und 70° liegen.In FIG. 8 is the range of the closing attenuation α and the opening loss β shown schematically. When pivoting the hinge part 7 relative to the side part 5 can be effected via the damper 30 in an angular range α before reaching the closed position, for example in a range between 0 ° and 30 °, a closing damping. Furthermore, an opening damping is effected via the damper 30 before reaching a maximum opening position in an angular range β. The opening damping can be effected, for example, in a range of at least 10 °, in particular at least 20 °, before reaching the maximum opening position. The maximum opening position can be 80 ° to 120 °, depending on the hinge type. In a middle region between the closing attenuation α and the opening damping β, the damper 30 is essentially ineffective in order not to obstruct an opening or closing of the door 3. The central region in which the damper 30 is ineffective can be, for example, between 45 ° and 70 °.

In Figur 9 ist die Öffnungsdämpfung schematisch dargestellt. Beim Öffnen der Tür 3 wirken zunächst kaum Kräfte durch den Dämpfer 30, abgesehen von vernachlässigbaren Reibungsverlusten beim Herausziehen der Kolbenstange 31. Erst bei einem Winkelbereich von etwa 60° bis 65° steigt die Dämpfungskraft an, bis zu der maximalen Öffnungsposition, die in Figur 9 mit 90° gewählt wurde. Die Öffnungsdämpfung ist somit im Wesentlichen in einem Bereich zwischen 65° und 90° wirksam.In FIG. 9 the opening loss is shown schematically. When opening the door 3 initially hardly act forces through the damper 30, apart from negligible friction losses when pulling out the piston rod 31. Only at an angular range of about 60 ° to 65 °, the damping force increases, up to the maximum opening position, in FIG. 9 was selected at 90 °. The opening loss is thus effective in a range between 65 ° and 90 ° substantially.

In Figur 10 ist die Schließdämpfung in einem Diagramm dargestellt. Beim Schließen der Tür 3 wirken bis zu einem Winkelbereich von 45° im Wesentlichen keine Kräfte durch den Dämpfer 30, bis auf vernachlässigbare Reibungskräfte. Erst vor Erreichen einer Schließposition, beispielsweise in einem Winkelbereich zwischen 0° und 35°, wird der Dämpfer 30 wirksam, wobei die Dämpfungskräfte am größten kurz vor Erreichen der Schließposition sind, so dass eine Tür 3 zumindest kurz vor Erreichen der Schließposition ausreichend abgebremst wird, um Anschlaggeräusche zu vermeiden. Im Hinblick auf die Schließbewegung ist noch anzumerken, dass die Feder 14 in einem Selbstanzugsbereich die Tür 3 in die geschlossene Position bewegt. Der Selbstanzugsbereich kann beispielsweise in einem Bereich zwischen 0° bis 40° liegen.In FIG. 10 the closing loss is shown in a diagram. When closing the door 3 substantially no forces act through the damper 30 up to an angular range of 45 °, except for negligible friction forces. Only before reaching a closed position, for example in an angle range between 0 ° and 35 °, the damper 30 is effective, the damping forces are greatest shortly before reaching the closed position, so that a door 3 is braked sufficiently at least shortly before reaching the closed position, to avoid impact noise. With regard to the closing movement, it should also be noted that the spring 14 in a self-tightening area moves the door 3 to the closed position. The self-tightening area may be, for example, in a range between 0 ° to 40 °.

In Figur 11 ist der Kolbenhub eines Dämpfers 30 über den Winkelbereich dargestellt. Der Dämpfer 30 ist als Druckdämpfer ausgebildet, so dass er in der Schließposition eine in das Dämpfergehäuse 32 eingefahrene Kolbenstange 31 aufweist. Die Kolbenstange 31 wird dann bei einer Öffnungsbewegung aus der Schließposition herausgezogen, wobei der Kolbenhub in einem anfänglichen Winkelbereich zwischen 0° und 30° größer ist als in einem mittleren Bereich. Die Kolbenstange 31 wird dann kurz vor Erreichen der maximalen Öffnungsposition wieder in das Dämpfergehäuse 32 eingefahren, wie dies in Figur 11 schematisch dargestellt ist.In FIG. 11 the piston stroke of a damper 30 is shown over the angular range. The damper 30 is designed as a pressure damper, so that it has a retracted into the damper housing 32 piston rod 31 in the closed position. The piston rod 31 is then pulled out of the closed position during an opening movement, the piston stroke being greater in an initial angle range between 0 ° and 30 ° than in a middle range. The piston rod 31 is then retracted shortly before reaching the maximum opening position in the damper housing 32, as in FIG. 11 is shown schematically.

Wird statt einem Druckdämpfer ein Zugdämpfer eingesetzt, ergibt sich ein Kolbenhub, wie er in Figur 12 dargestellt ist. In einer Schließposition ist die Kolbenstange 31 dann zunächst aus dem Dämpfergehäuse 32 ausgefahren und wird dann beim Bewegen des Scharniers 4 eingefahren. Die Dämpfungskräfte entstehen dann beim Herausziehen der Kolbenstange aus dem Dämpfergehäuse.If a damper is used instead of a pressure damper, the result is a piston stroke, as in FIG. 12 is shown. In a closed position, the piston rod 31 is then first extended out of the damper housing 32 and is then retracted when moving the hinge 4. The damping forces then arise when pulling out the piston rod from the damper housing.

In dem dargestellten Ausführungsbeispiel ist das Umlenkelement unmittelbar mit der Kolbenstange 31 des Dämpfers 30 verbunden. Es ist natürlich auch möglich, ein oder mehrere Bauteile zwischen dem Umlenkelement und dem Dämpfer vorzusehen, ohne das mechanische Wirkprinzip des Scharniers zu modifizieren. Das Umlenkelement 15 ist ferner über einen Hebel 19 mit dem Führungshebel 9 verbunden. Es ist auch möglich, das Umlenkelement 15 unmittelbar mit dem Traghebel 8 oder dem Führungshebel 9 zu verbinden oder noch weitere Hebel oder Bauteile dazwischen anzuordnen, ohne die erfindungsgemäße Mechanik des Scharniers 4 zu verändern.In the illustrated embodiment, the deflecting element is connected directly to the piston rod 31 of the damper 30. Of course, it is also possible to provide one or more components between the deflecting element and the damper, without modifying the mechanical working principle of the hinge. The deflecting element 15 is also connected via a lever 19 to the guide lever 9. It is also possible to connect the deflecting element 15 directly to the support lever 8 or the guide lever 9 or to arrange further levers or components therebetween, without changing the mechanism of the hinge 4 according to the invention.

Statt dem als Druckdämpfer ausgebildeten Dämpfer 30 kann auch ein Zugdämpfer eingesetzt werden, mittels dem ebenfalls eine Öffnungs- und Schließdämpfung bewirkt werden kann.Instead of the shock absorber 30 designed as a pressure damper, it is also possible to use a damper by means of which an opening and closing damping can likewise be effected.

Der Dämpfer 30 kann zudem einstellbar ausgebildet sein, um die Dämpfungskräfte an das Gewicht der jeweiligen Tür 3 anpassen zu können. Entsprechende Mechaniken und Verstellmechanismen sind bekannt. Zudem kann der Dämpfer auch mehr Bauteile als das Dämpfergehäuse und eine Kolbenstange aufweisen, beispielsweise kann an gegenüberliegenden Seiten des Dämpfers eine Kolbenstange vorgesehen sein, die dann in das Dämpfergehäuse eingeschoben oder herausgezogen wird.The damper 30 can also be designed to be adjustable in order to be able to adapt the damping forces to the weight of the respective door 3. Corresponding mechanisms and adjustment mechanisms are known. In addition, the damper may also have more components than the damper housing and a piston rod, for example, a piston rod may be provided on opposite sides of the damper, which is then inserted or withdrawn into the damper housing.

In einem weiteren Ausführungsbeispiel kann die Feder 14 das Scharnierteil 7 in einem Selbstöffnungsbereich in eine Öffnungsrichtung vorspannt, wobei vorzugsweise dieselbe Feder 14 das Scharnierteil 7 in dem Selbsteinzugsbereich des Scharniers 4 in eine geschlossene Position vorspannt. Durch die Vorspannung in Öffnungsrichtung kann eine Tür oder Klappe in einer vorbestimmten Öffnungsposition gehalten werden. Die Vorspannung in Öffnungsrichtung kann beispielsweise ab einem Öffnungswinkel von 45°, insbesondere von mehr als 60° oder 70° bis zur maximalen Öffnungsposition erfolgen.In another embodiment, the spring 14 biases the hinge part 7 in a self-opening area in an opening direction, preferably with the same spring 14 biasing the hinge part 7 in the self-retraction area of the hinge 4 into a closed position. By the bias in the opening direction, a door or flap can be kept in a predetermined opening position. The bias in the opening direction can be done, for example, from an opening angle of 45 °, in particular of more than 60 ° or 70 ° to the maximum opening position.
