Definitions
- hinges with their own locking mechanism are largely known.
- the main advantage of this is that a separate locking part, for example a magnetic catch, is saved in the furniture.
- An example of such a hinge can be found in DE-OS 29 51 986.
- a separate pressure piece is rotatably mounted on the inner articulated lever, which is acted upon by a leg spring.
- the pressure piece is a leg spring.
- the leg of the leg spring has two curvature sections with curvatures facing each other.
- the hinge according to the invention has a hinge arm 1 which is fastened to a furniture side wall 7 by means of a base plate 8.
- the base plate 8 is fastened to the furniture side wall 7 in a conventional manner by means of screws or dowels.
- the hinge arm 1 is held on the base plate 8 by means of a clamping screw.
- an adjusting screw 11 is further provided for the joint adjustment, which is supported in a nut thread in the hinge arm 1 and is supported on the base plate 8.
- the hinge housing 2 of the hinge is inserted into the door leaf 9.
- the hinge arm 1 is connected to the hinge housing 2 by means of the articulated levers 3, 6, which are mounted on articulated axes 12, 13 on the hinge arm 1 and on articulated axes 14, 15 in the hinge housing 2.
- the leg spring 21 is supported directly on the hinge axes 12, 13 of the hinge arm 1.
- the hinge axis 13 of the outer hinge lever 3, on which the leg 4 of the leg spring 21, which is designed as a pressure piece, is displaced, is provided with a roller 23 in order to reduce the friction.
- the leg 4 of the leg spring 21, which is designed as a pressure piece, has two curve sections 4 ′ and 4 ′′ with mutually opposite curves.
- the outer curve section 4 ′ corresponds to the open position of the hinge. In the closed position, the pressure point lies between this leg of the leg spring 21 and the roller 23 of the hinge axis 13 between the section 4 'and the section 4' of the leg of the leg spring 21 which is designed as a pressure piece 4.
- leg spring 21 Due to the arrangement of the leg spring 21 according to the invention, this is constantly supported on the hinge axes 12, 13, but in the closed position it nevertheless presses the inner hinge lever 6 in the closing direction, ie. H. the door leaf 9 is kept closed.
- leg spring 21 When the door leaf 9 is opened, the leg spring 21 is not relieved of pressure, so that a counterpressure does not have to be overcome when the door leaf is being closed or opened.

Description
Die Erfindung bezieht sich auf ein Scharnier für Möbeltüren mit einem Schließmechanismus, mit einem türflügelseitigen Scharniergehäuse, in dem die inneren Enden von zwei Gelenkhebeln drehbar gelagert sind, deren äußere Enden unter Bildung eines Gelenkvierecks an einem Scharnierarm angreifen, wobei innerhalb des Scharnierarmes ein federvorgespanntes Druckstück lagert, das am inneren Gelenkhebel drehbar gelagert ist und sich in der Schließstellung des Scharnieres an der scharnierarmseitigen Gelenkachse des äußeren Gelenkhebels abstützt, mit einer vorzugsweise konvexen Abstützfläche am Druckstück.The invention relates to a hinge for furniture doors with a locking mechanism, with a hinge housing on the door leaf, in which the inner ends of two articulated levers are rotatably mounted, the outer ends of which act on a hinge arm to form a four-bar linkage, a spring-loaded pressure piece being mounted within the hinge arm , which is rotatably mounted on the inner articulated lever and is supported in the closed position of the hinge on the hinge arm-side articulation axis of the outer articulated lever, with a preferably convex support surface on the pressure piece.
Derartige Scharniere mit einem eigenen Schließmechanismus sind weitgehend bekannt. Ihr Vorteil ist vor allem darin zu sehen, daß ein separater Schließteil, beispielsweise ein Magnetschnapper, beim Möbel eingespart wird. Ein Beispiel für ein derartiges Scharnier ist der DE-OS 29 51 986 zu entnehmen. Dabei ist auf den inneren Gelenkhebel ein separates Druckstück drehbar gelagert, das von einer Schenkelfeder beaufschlagt wird.Such hinges with their own locking mechanism are largely known. The main advantage of this is that a separate locking part, for example a magnetic catch, is saved in the furniture. An example of such a hinge can be found in DE-OS 29 51 986. A separate pressure piece is rotatably mounted on the inner articulated lever, which is acted upon by a leg spring.
Aufgabe der Erfindung ist es, ein Scharnier der eingangs erwähnten Art zu schaffen, bei dem der Schließmechanismus noch kompakter und konstruktiv einfacher ausgeführt ist.The object of the invention is to provide a hinge of the type mentioned, in which the locking mechanism is made even more compact and structurally simple.
Dies wird erfindungsgemäß dadurch erreicht, daß das Druckstück Schenkel einer Schenkelfeder ist.This is achieved according to the invention in that the pressure piece is a leg spring.
Durch die Verwendung einer Schenkelfeder wird mit einfachen Mitteln gute Funktionssicherheit erreicht da diese zum Unterschied von einer Schraubenfeder im Scharnierarm einfach ohne Führungsmittel verankert werden kann. Außerdem kann auf ein zusätzliches Druckstück im Schließmechanismus verzichtet werden.By using a leg spring, good functional reliability is achieved with simple means since, unlike a helical spring, this can be anchored in the hinge arm easily without guide means. In addition, there is no need for an additional pressure piece in the locking mechanism.
Ein Ausführungsbeispiel der Erfindung sieht vor, daß der innere Gelenkhebel als doppelarmiger Hebel ausgeführt ist und daß die Schenkelfeder am in den Scharnierarm ragenden Arm des Gelenkhebels drehbar gelagert ist.An embodiment of the invention provides that the inner articulated lever is designed as a double-armed lever and that the leg spring is rotatably mounted on the arm of the articulated lever projecting into the hinge arm.
Vorteilhaft ist vorgesehen, daß die Schenkelfeder mit ihren Schenkeln ständig mittelbar oder unmittelbar auf die beiden Gelenkachsen des Scharnierarmes drückt.It is advantageously provided that the leg spring constantly or indirectly presses with its legs on the two joint axes of the hinge arm.
Um den Übergang vom Schließbereich in den Öffnungsbereich genau bestimmen zu können, sieht ein Ausführungsbeispiel den Erfolg vor, daß der Schenkel der Schenkelfeder, der auf die Gelenkachse des äußeren Gelenkhebels oder einen anderen scharnierarmfesten Teil drückt, diskontinuierlich gebogen ist und eine Steuerkurve beschreibt.In order to be able to precisely determine the transition from the closing area to the opening area, one exemplary embodiment provides for the success that the leg of the leg spring, which presses on the articulation axis of the outer articulated lever or another part fixed to the hinge arm, is bent discontinuously and describes a control curve.
Vorteilhaft ist dabei vorgesehen, daß der Schenkel der Schenkelfeder zwei Krümmungsabschnitte mit einander entgegengerichteter Krümmung aufweist.It is advantageously provided that the leg of the leg spring has two curvature sections with curvatures facing each other.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Figuren der beiliegenden Zeichnungen eingehend beschrieben.An exemplary embodiment of the invention is described in detail below with reference to the figures in the accompanying drawings.
Die Fig. 1 zeigt einen Schnitt durch ein erfindungsgemäßes Scharnier in der Schließstellung und die Fig. 2 zeigt einen gleichen Schnitt durch ein erfindungsgemäßes Scharnier in der Offenstellung des Scharnieres.1 shows a section through a hinge according to the invention in the closed position and FIG. 2 shows a same section through a hinge according to the invention in the open position of the hinge.
Wie aus den Figuren der Zeichnung ersichtlich, weist das erfindungsgemäße Scharnier einen Scharnierarm 1 auf, der mittels einer Grundplatte 8 an einer Möbelseitenwand 7 befestigt ist. Die Befestigung der Grundplatte 8 an der Möbelseitenwand 7 erfolgt auf herkömmliche Weise mittels Schrauben oder Dübeln. Der Scharnierarm 1 ist auf der Grundplatte 8 mittels einer Klemmschraube gehalten. Am Scharnier ist weiters eine Verstellschraube 11 für die Fugenverstellung vorgesehen, die in einem Muttergewinde im Scharnierarm 1 lagert und sich an der Grundplatte 8 abstützt. In den Türflügel 9 ist das Scharniergehäuse 2 des Scharnieres eingesetzt.As can be seen from the figures of the drawing, the hinge according to the invention has a
Der Scharnierarm 1 ist mit dem Scharniergehäuse 2 mittels der Gelenkhebel 3, 6 verbunden, die auf Gelenkachsen 12, 13 am Scharnierarm 1 und auf Gelenkachsen 14, 15 im Scharniergehäuse 2 lagern.The
Der innere Gelenkhebel 6 ist als zweiarmiger Hebel ausgeführt, der sich um die Gelenkachse 12 des Scharnierarmes 1 dreht. Am freien Ende des Gelenkhebelarmes 6', d. h. außerhalb der Lagerstellen der Gelenkachsen 12, 14, ist auf einem Zapfen 16 das Druckstück gelagert, das vom Schenkel einer Schenkelfeder 21 gebildet wird.The inner articulated
Die Schenkelfeder 21 stützt sich direkt an den Gelenkachsen 12, 13 des Scharnierarmes 1 ab. Die Gelenkachse 13 des äußeren Gelenkhebels 3, an der der Schenkel 4 der Schenkelfeder 21 verschoben wird, der als Druckstück ausgebildet ist, ist mit einer Rolle 23 versehen, um die Reibung herabzusetzen.The
Der Schenkel 4 der Schenkelfeder 21, welcher als Druckstück ausgeführt ist, weist zwei Kurvenabschnitte 4' und 4" mit einander entgegengerichtetem Kurvenverlauf auf. Der äußere Kurvenabschnitt 4' entspricht der Offenstellung des Scharnieres. In der Schließstellung liegt der Druckpunkt zwischen diesem Schenkel der Schenkelfeder 21 und der Rolle 23 der Gelenkachse 13 zwischen dem Abschnitt 4' und dem Abschnitt 4' des als Druckstück 4 ausgeführten Schenkels der Schenkelfeder 21.The
Durch die erfindungsgemäße Anordnung der Schenkelfeder 21 stützt sich diese zwar ständig an den Gelenkachsen 12, 13, aber sie drückt dennoch in der Schließstellung den inneren Gelenkhebel 6 in die Schließrichtung, d. h. der Türflügel 9 wird geschlossen gehalten.Due to the arrangement of the
Beim Öffnen des Türflügels 9 kommt es zu keiner Entlastung der Schenkelfeder 21, so daß weder beim Schließen noch beim Öffnen des Türflügels ein Gegendruck überwunden werden muß.When the
