Es ist daher Aufgabe der vorliegenden Erfindung, ein Mehrgelenkscharnier zu schaffen, das einen kompakten Aufbau und eine verbesserte Dämpfungs- und Schließfunktion besitzt.It is therefore the object of the present invention to create a multi-joint hinge which has a compact structure and an improved damping and closing function.
Diese Aufgabe wird mit einem Mehrgelenkscharnier mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a multi-joint hinge with the features of
Erfindungsgemäß sind bei dem Mehrgelenkscharnier ein Dämpfungselement zum Abbremsen einer Schließbewegung und ein Federelement zum Anziehen des Türlagers parallel geschaltet. Dadurch können das Dämpfungselement und das Federelement zwischen den gleichen Hebeln einer Hebelmechanik oder parallel zwischen dem Basisteil und einem Hebel oder dem Türlager und einem Hebel geschaltet sein, so dass die Dämpfungs- und Vorspannfunktion kompakt aufgebaut werden kann. Durch die parallele Schaltung von Dämpfungselement und Federelement wird die Relativbewegung zwischen dem Dämpfungselement und dem Federelement reduziert, so dass der benötigte Bauraum verringert wird.According to the invention, a damping element for braking a closing movement and a spring element for tightening the door hinge are connected in parallel in the multi-joint hinge. As a result, the damping element and the spring element can be connected between the same levers of a lever mechanism or in parallel between the base part and a lever or the door bearing and a lever, so that the damping and pretensioning function can be constructed compactly. The parallel connection of the damping element and the spring element reduces the relative movement between the damping element and the spring element, so that the required installation space is reduced.
Vorzugsweise sind das Dämpfungselement und das Federelement parallel zwischen dem Türlager und einem Umlenkhebel der Hebelmechanik geschaltet. Das Dämpfungselement und das Federelement werden dann zusammen mit dem Türlager und dem Umlenkhebel bewegt, so dass ein Bauraum benachbart zu einer Schwenkachse an dem Basisteil für die Hebelmechanik genutzt wird, was eine verbesserte Kraftabtragung und gute Hebelverhältnisse ermöglicht.The damping element and the spring element are preferably connected in parallel between the door bearing and a reversing lever of the lever mechanism. The damping element and the spring element are then moved together with the door bearing and the deflection lever, so that an installation space adjacent to a pivot axis on the base part is used for the lever mechanism, which enables improved force transfer and good lever ratios.
Das Dämpfungselement umfasst mindestens einen Lineardämpfer, vorzugsweise zwei Lineardämpfer, mit einer Dämpfungsachse, und das Federelement weist mindestens eine linear wirkende Feder mit einer Federachse auf, wobei die Dämpfungsachse und die Federachse über den gesamten Schwenkbereich des Türlagers im Wesentlichen parallel zueinander ausgerichtet sind. Die Dämpfungsachse und die Federachse müssen dabei nicht exakt parallel ausgerichtet sein, sondern in einem Winkelbereich von kleiner 10°, so dass das Dämpfungselement und das Federelement dicht nebeneinander angeordnet sind.The damping element comprises at least one linear damper, preferably two linear dampers, with a damping axis, and the spring element has at least one linearly acting spring with a spring axis, the damping axis and the spring axis being aligned essentially parallel to one another over the entire pivoting range of the door hinge. The damping axis and the spring axis do not have to be aligned exactly parallel, but in an angular range of less than 10 °, so that the damping element and the spring element are arranged close to one another.
Das Mehrgelenkscharnier ist vorzugsweise als Sieben-Gelenk-Scharnier ausgebildet, wobei die Hebelmechanik zwischen dem Türlager und dem Basisteil vier Hebel umfasst. In einer Schließposition ist das Mehrgelenkscharnier im Wesentlichen kastenförmig ausgebildet. Die Hebelmechanik kann dabei durch zwei im Wesentlichen plattenförmige Abdeckungen verdeckt liegend angeordnet sein, wobei die Abdeckungen an gegenüberliegenden Seiten des Mehrgelenkscharniers angeordnet sind, und vorzugsweise eine Kurvenführung aufweisen, um die Hebelmechanik auch in verschiedenen Öffnungspositionen verdecken zu können.The multi-joint hinge is preferably designed as a seven-joint hinge, the lever mechanism comprising four levers between the door bearing and the base part. In a closed position, the multi-joint hinge is essentially box-shaped. The lever mechanism can be arranged in a concealed manner by two essentially plate-shaped covers, the covers being arranged on opposite sides of the multi-joint hinge and preferably having a curved guide in order to be able to cover the lever mechanism in different opening positions.
Die Hebelmechanik weist in einer Ausgestaltung einen Umlenkhebel mit einer Aufnahme, insbesondere gebildet durch mindestens eine Achse, zwischen zwei Platten auf, wobei die Platten über mindestens einen Verbindungssteg miteinander verbunden sind. An der Aufnahme des Umlenkhebels können dabei das Dämpfungselement und das Federelement eingefügt sein, so dass diese geschützt, vorzugsweisezwischen den mindestens zwei Platten und dem Verbindungssteg gebildeten Innenraum, angeordnet sind. In Schließposition befindet sich das Dämpfungselement mit seinen Dämpfungsachsen nahezu vollständig innerhalb des gebildeten Innenraums des Umlenkhebels wobei es sich in Öffnungsposition mit zumindest einer Dämpfungsachse außerhalb des gebildeten Innenraums des Umlenkhebels befindet. An dem Türlager oder dem Umlenkhebel kann dabei eine Kappe vorgesehen sein, um den Innenraum zu dem Mehrgelenkscharnier oder dem Umlenkhebel abzudecken, wobei die Kappe relativ zu dem Türlager oder dem Umlenkhebel verschiebbar gelagert ist. Die Kappe kann dabei über Rastelemente an mindestens einem Lineardämpfer in Richtung Dämpfungsachse verschieblich gelagert sein und /oder an einer Achse des Umlenkhebels drehbar gelagert sein.In one embodiment, the lever mechanism has a deflection lever with a receptacle, in particular formed by at least one axis, between two plates, the plates being connected to one another via at least one connecting web. The damping element and the spring element can be inserted into the receptacle of the reversing lever so that they are arranged in a protected manner, preferably between the interior space formed between the at least two plates and the connecting web. In the closed position, the damping element with its damping axes is almost completely inside the interior space formed by the reversing lever, while in the open position with at least one damping axis it is located outside the interior space formed in the reversing lever. On the door bearing or the reversing lever a cap can be provided to the interior to the To cover multi-joint hinge or the reversing lever, the cap being mounted displaceably relative to the door bearing or the reversing lever. The cap can be mounted displaceably in the direction of the damping axis via locking elements on at least one linear damper and / or rotatably mounted on an axis of the reversing lever.

An dem Basisteil 2 ist eine Achse 12 ausgebildet, an der ein Hebel 4 drehbar gelagert ist. An dem Hebel 4 ist über eine Achse 22 der Umlenkhebel 20 drehbar gelagert, der über eine Achse 38 gelenkig mit dem Türlager 3 verbunden ist. Zwischen dem Umlenkhebel 20 und dem Türlager 3 ist eine Kappe 11 vorgesehen, die eine Öffnung an dem Umlenkhebel 20 überdeckt.On the

Das Mehrgelenkscharnier 1 umfasst ferner ein Dämpfungselement 30 zum Abbremsen einer Schließbewegung. Das Dämpfungselement 30 weist einen oder mehrere Lineardämpfer auf, die gelenkig mit dem Umlenkhebel 20 und dem Türlager 3 verbunden sind. Parallel zu dem Dämpfungselement 30 ist ein Federelement 40 geschaltet, das ebenfalls zwischen dem Türlager 3 und dem Umlenkhebel 20 geschaltet ist. Das Federelement 40 umfasst eine als Spiralfeder ausgebildete Feder 41, die über einen teleskopierbaren Federhalter geführt ist. Der Federhalter umfasst ein inneres Teil 42, das gelenkig über eine Achse 46 mit dem Umlenkhebel 20 verbunden ist, und ein äußeres Teil 44, das hülsenförmig eine Federachse 43 des inneren Teils 42 umgibt. Das äußere Teil 44 ist endseitig über einen Lagerabschnitt 45 an einer Achse 56 gelenkig mit einem Federhebel 50 verbunden. Der Federhebel 50 ist über eine Achse 59 drehbar an dem Umlenkhebel 20 gehalten. Der Federhebel 50 bildet ferner ein Lager für eine Rolle 51 aus, die an einem Nockenelement 54 abrollt. Das Nockenelement 54 ist über zwei Achsen 22 und 55 mit dem Hebel 4 verbunden, und über das Nockenelement 54 wird vorgegeben, in welchem Bereich die Feder 41 spannt und entspannt.The

Der Umlenkhebel 20 ist an der Achse 38 an dem Türlager 3 fixiert. Die Achse 33 durchgreift dabei zwei Ösen 31 der Lineardämpfer, wobei die Lineardämpfer des Dämpfungselementes 30 auf der gegenüberliegenden Seite ebenfalls Ösen 32 oder Rastelemente aufweisen, die an einer Achse 34 innerhalb eines Halters 21 fixiert sind. Der Halter 21 hält die Ösen 32 der Dämpfer auf der Achse 34 auf einen definierten Abstand zueinander. Die Achse 34 durchgreift zwei Öffnungen 27 an dem Umlenkhebel 20, die benachbart zu Öffnungen 28 zur Durchführung der Achse 22 vorgesehen sind.The reversing

Das Federelement 40 mit der Feder 41 zwischen dem inneren Teil 42 und dem äußeren Teil 44 ist über den Federhebel 50 und die Rolle 51 abgestützt, wobei die Rolle 51 an dem Nockenelement 54 entlang einer Lauffläche 58 abrollt. Wird das Mehrgelenkscharnier 1 geschlossen, bewegt sich die Rolle 51 über einen Vorsprung an dem Nockenelement 54 und kann ab einem vorbestimmten Öffnungswinkel, beispielsweise bei etwa 30°, für ein Entspannen der Feder 41 sorgen, so dass in dem Schließbereich zwischen der Schließposition und dem Öffnungswinkel von etwa 30° das Federelement 40 wirksam ist und das Türlager 3 in Schließrichtung spannt.The
Der Einsatz von zwei parallelen Lineardämpfern ermöglicht das Aufbringen hoher Dämpfungskräfte und das Abbremsen auch schwerer Türgewichte. Die Lineardämpfer sind vorzugsweise als Fluiddämpfer, beispielsweise mit Öl, wie Silikonöl, gefüllt. Auch andere Lineardämpfer mit einem Zylinder und einem darin verfahrbar gelagerten Kolben und einer Kolbenstange können eingesetzt werden.The use of two parallel linear dampers enables high damping forces to be applied and even heavy door weights to be braked. The linear dampers are preferably filled as fluid dampers, for example with oil, such as silicone oil. Other linear dampers with a cylinder and a piston and a piston rod mounted therein so as to be movable can also be used.
Bei dem Federelement 40 ist jede Feder 41 als Druckfeder ausgebildet. Es ist natürlich auch möglich, die Feder 41 als Zugfeder auszubilden oder mehr als nur eine Feder 41 für das Federelement 40 einzusetzen.In the
Optional kann über die Lineardämpfer auch eine Offnungsdämpfung und Schließdämpfung erreicht werden, um das Mehrgelenkscharnier 1 bei Erreichen der maximalen Offnungsposition und Schließposition über das Dämpfungselement 30 abzubremsen.Optionally, opening and closing damping can also be achieved via the linear dampers, in order to decelerate the
Ebenso ist es möglich ein stufiges Dämpfungskraftverhalten bei einem Schließ- oder Öffnungsvorgang des Scharniers zu erzeugen, in dem die Dämpfer bei unterschiedlichen Öffnungs- oder Schließwinkeln eine unterschiedliche Dämpfwirkung bereitstellen.It is also possible to generate a stepped damping force behavior during a closing or opening process of the hinge, in which the dampers provide a different damping effect at different opening or closing angles.
