Description

Stellarmantrieb für Klappen von Schränken Actuating arm drive for flaps of cupboards
Die Erfindung bezieht sich auf einen Stellarmantrieb für Klappen von Schränken, mit einem an einer Klappe angelenkten Stellarm, der von mindestens einer Feder beaufschlagt wird und über einen durch zwei Endlagen begrenzten Schwenkbereich kippbar ist.The invention relates to an actuating arm drive for flaps of cupboards, with an actuating arm hinged to a flap, which is acted upon by at least one spring and can be tilted over a swivel range limited by two end positions.
Ein derartiger Stellarmantrieb erlaubt das gesteuerte Öffnen und Schließen einer Klappe. Derartige Klappen sind insbesondere bei Hochschränken vorgesehen. Sie können als Einfachklappen oder auch als Faltklappen ausgeführt sein. Ein Beispiel für ein Möbel mit einem derartigen Stellarmantrieb ist in der DE 101 45 856 A1 gezeigt.Such an actuator arm allows the controlled opening and closing of a flap. Such flaps are provided in particular in tall cupboards. They can be designed as single flaps or as folding flaps. An example of a piece of furniture with such an actuator arm drive is shown in DE 101 45 856 A1.
Aufgabe der Erfindung ist es, einen derartigen Stellarmantrieb zu verbessern.The object of the invention is to improve such an actuator drive.
Die erfindungsgemäße Aufgabe wird dadurch gelöst, dass mit dem Stellarm ein Steuerteil gelenkig verbunden ist, der eine Steuerkurve aufweist, auf die die mindestens eine Feder drückt.The object of the invention is achieved in that a control part is articulated to the actuating arm and has a control cam on which the at least one spring presses.
Durch die erfindungsgemäße Ausführung des Stellarmantriebes wird die Klappe vom Stellarmantrieb knapp vor Erreichen ihrer untersten Endlage in die Schließstellung gedrückt. Falls gewünscht, kann die Steuerkurve so ausgebildet sein, dass die Klappe knapp vor Erreichen ihrer obersten Endlage in die Offenstellung gedrückt wird. Dazwischen gibt es dann einen neutralen Schwenkbereich, in dem die Klappe vom Stellarmantrieb ständig im Gleichgewicht gehalten wird.Due to the embodiment of the actuator arm drive according to the invention, the flap is pressed into the closed position by the actuator arm drive just before reaching its lowest end position. If desired, the control cam can be designed such that the flap is pressed into the open position just before reaching its uppermost end position. In between there is a neutral swivel range in which the flap is constantly balanced by the actuator arm drive.
Vorteilhaft ist vorgesehen, dass zwischen der mindestens einen Feder und dem Steuerteil ein linear verfahrbarer Druckteil vorgesehen ist, der an der Steuerkurve anliegt.It is advantageously provided that a linearly movable pressure part is provided between the at least one spring and the control part, which rests on the control cam.
Entweder ist der Steuerteil am Druckteil drehbar und relativ zu diesem verschiebbar gelagert oder es ist ein linear verfahrbarer Schlitten vorgesehen, auf dem der Steuerteil drehbar gelagert ist.Either the control part is rotatably mounted on the pressure part and displaceable relative to it, or a linearly movable carriage is provided on which the control part is rotatably mounted.
Die Steuerkurve ist vorzugsweise als konvex gekrümmte Bahn am, in Bezug auf die Lagerstelle am Stellarm, distalen Ende des Steuerteiles ausgeführt.The control curve is preferably designed as a convexly curved path on the distal end of the control part with respect to the bearing point on the actuating arm.
Ein weiteres Ausführungsbeispiel der Erfindung sieht vor, dass der Stellarmantrieb mit einem Dämpfer versehen ist, der die Kippbewegung des Stellarmes mindestens über einen Teil des Schwenkbereiches dämpft. Die Dämpfung beginnt vorzugsweise vor Erreichen der beiden Endlagen und dauert an, bis die jeweilige Endlage erreicht ist.A further exemplary embodiment of the invention provides that the actuating arm drive is provided with a damper which prevents the tilting movement of the actuating arm at least over part of the Dampens swivel range. The damping preferably begins before reaching the two end positions and continues until the respective end position is reached.

Der erfindungsgemäße Stellarmantrieb 1 ist zusammen mit dem Stellarm 2 an einer Seitenwand 3 eines Hochschankes befestigt.The actuating arm drive 1 according to the invention is fastened together with the actuating arm 2 to a side wall 3 of a high bar.
Das freie Ende des Stellarmes 2 ist gelenkig mit einer Klappe 4 verbunden. Der Stellarm 2 ist auf einer Achse 5 des Stellarmantriebes 1 drehbar gelagert. Weiters ist der Stellarm 2 als zweiarmiger Hebel ausgeführt mit einem kurzen Hebelarm 6, mit dem ein Steuerteil 7 über eine Achse 8 gelenkig verbunden ist.The free end of the actuating arm 2 is articulated to a flap 4. The actuating arm 2 is rotatably mounted on an axis 5 of the actuating arm drive 1. Furthermore, the actuating arm 2 is designed as a two-armed lever with a short lever arm 6, with which a control part 7 is articulated via an axis 8.
Der Steuerteil 7 weist am, in Bezug auf die Achse 8, distalen Ende eine Steuerkurve 9 in der Form einer konvexen Kurvenbahn auf.The control part 7 has, at the distal end with respect to the axis 8, a control cam 9 in the form of a convex cam track.
Im Gehäuse 10 des Stellarmantriebes 1 lagern mehrere, vorzugsweise drei, Druckfedern 11 , die über einen Druckteil 12 auf die Steuerkurve 9 des Steuerteiles 7 drücken.In the housing 10 of the actuating arm drive 1 there are several, preferably three, compression springs 11 which press on the control curve 9 of the control part 7 via a pressure part 12.
Die Steuerkurve 9 ist so ausgelegt, dass der Stellarm 2 knapp vor Erreichen seiner obersten Endlage von den Federn 11 in die oberste Endstellung gedrückt wird und knapp vor Erreichen seiner untersten Endlage in die unterste Schließstellung. Dazwischen gibt es einen neutralen Bereich, in dem die Klappe 4 im Gleichgewicht gehalten ist.The control curve 9 is designed such that the actuating arm 2 is pressed into the uppermost end position by the springs 11 just before reaching its uppermost end position and just before Reaching its lowest end position in the lowest closed position. In between there is a neutral area in which the flap 4 is kept in balance.
Im Ausführungsbeispiel nach den Fig. 4 ist der Steuerteil 7 auf einem linear verfahren Schlitten 15 über eine Achse 16 drehbar gelagert. Zwischen dem linear verfahrbaren Schlitten 15 und einem am Gehäuse 10 ausgebildeten ortsfesten Anschlag 17 ist ein Dämpfer, vorzugsweise ein Lineardämpfer 18 angeordnet. Weiters weist der Stellarm 2 einen Anschlag 19 für den Lineardämpfer 18 auf. Wird die Klappe 4 angehoben und der Stellarm 2 nähert sich der obersten Endlage, dann drückt der linear verfahrbare Schlitten 15 auf den Lineardämpfer 18, der andererseits vom Anschlag 17 abgestützt wird, sodass der Lineardämpfer 18 die Schwenkbewegung des Stellarmes 2 in diesem Bereich dämpft.In the exemplary embodiment according to FIG. 4, the control part 7 is rotatably mounted on a linearly displaced slide 15 via an axis 16. A damper, preferably a linear damper 18, is arranged between the linearly movable carriage 15 and a stationary stop 17 formed on the housing 10. Furthermore, the actuating arm 2 has a stop 19 for the linear damper 18. If the flap 4 is raised and the actuating arm 2 approaches the uppermost end position, then the linearly displaceable slide 15 presses on the linear damper 18, which is supported on the other hand by the stop 17, so that the linear damper 18 dampens the pivoting movement of the actuating arm 2 in this area.
Wird die Klappe 4 abgesenkt und der Stellarm 2 nähert sich seiner unteren Endlage, dann drückt der Anschlag 19 des Stellarmes 2 auf den Lineardämpfer 18, dessen dem Anschlag 19 gegenüberliegendes Ende vom linear verfahren Schlitten 15 abgestützt wird. Auf diese Art wird der Stellarm 2 vor Erreichen der unteren Endlage, d.h. vor Erreichen der Schließstellung der Klappe 4, gedämpft.If the flap 4 is lowered and the actuating arm 2 approaches its lower end position, then the stop 19 of the actuating arm 2 presses on the linear damper 18, the end of which opposite the stop 19 is supported by the linearly displaceable slide 15. In this way, the actuating arm 2 is reached before reaching the lower end position, i.e. damped before reaching the closed position of the flap 4.
Weiters ist im Gehäuse 1 noch ein Anschlag 20 vorgesehen, der die oberste Endlage des Stellarmes 2 festlegt.Furthermore, a stop 20 is provided in the housing 1, which defines the top end position of the actuating arm 2.
Im Ausführungsbeispiel nach den Fig. 5 ist der Steuerteil 7 drehbar auf dem Druckteil 12 gelagert, und zwar mittels einer Achse 13, die durch ein Langloch 14 im Druckteil 12 ragt. Aufgrund der Achse 13 und des Langloches 14 ist der Steuerteil 7 relativ zum Druckteil 12 sowohl drehbar als auch linear verschiebbar gelagert. Es kann daher auf den Schlitten 15 verzichtet werden. Das Diagramm der Fig. 10 zeigt den Kräfteverlauf während des Öffnens der Klappe 4, wobei die obere Klappe 4 in der Offenstellung einen Winkel von 110° zur Schließebene des Möbels einnimmt. Da der Druckteil 12 aus Kunststoff ausgeführt sein kann, ist er mit einer Metallplatte 21 versehen, an der der Steuerteil 7 anliegt. Vorteilhaft ist die Metallplatte 21 im Druckteil 12 in der Höhe verschiebbar, beispielsweise in einem gefetteten Gleitlager geführt. Auf diese Art entsteht keine Reibung zwischen dem Steuerteil 7 und der Metallplatte 21.In the exemplary embodiment according to FIG. 5, the control part 7 is rotatably mounted on the pressure part 12, specifically by means of an axis 13 which projects through an elongated hole 14 in the pressure part 12. Due to the axis 13 and the elongated hole 14, the control part 7 is both rotatably and linearly displaceable relative to the pressure part 12. The carriage 15 can therefore be dispensed with. The diagram in FIG. 10 shows the course of forces during the opening of the flap 4, the upper flap 4 in the open position taking an angle of 110 ° to the closing plane of the piece of furniture. Since the pressure part 12 can be made of plastic, it is provided with a metal plate 21 against which the control part 7 rests. The height of the metal plate 21 in the pressure part 12 is advantageously adjustable, for example guided in a greased slide bearing. In this way, there is no friction between the control part 7 and the metal plate 21.
Der erfindungsgemäße Stellarmantrieb ist sowohl bei Möbeln mit einfachen Klappen 4, wie in den Fig. 11 bis 13 gezeigt, als auch bei Möbeln mit einer doppelten Klappe, wie in den Fig. 1 und 2 gezeigt, einsetzbar. Bei einer doppelten Klappe ist die obere Klappe 4 direkt über ein Scharnier 24 mit dem Oberboden 22 des Möbels verbunden. Im Falle einer Einfachklappe ist neben dem Stellarm 2 ein Gelenkhebel 23 vorgesehen.The actuator arm drive according to the invention is both in the case of furniture with simple flaps 4, as shown in FIGS. 11 to 13, and in the case of furniture with a double flap, as in FIG. 1 and 2 shown, can be used. In the case of a double flap, the upper flap 4 is connected directly to the upper floor 22 of the piece of furniture via a hinge 24. In the case of a single flap, an articulated lever 23 is provided next to the actuating arm 2.
Der Stellarmantrieb 1 ist derartig ausgeführt, dass er wahlweise an der linken oder an der rechten Seitenwand 3 eines Möbels befestigbar ist. Er weist eine Abdeckkappe auf, die ebenso wahlweise an den einander gegenüberliegenden Flachseiten des Stellarmantriebes 1 befestigbar ist.The actuating arm drive 1 is designed such that it can be attached either to the left or to the right side wall 3 of a piece of furniture. It has a cover cap which can also be optionally fastened to the flat sides of the actuating arm drive 1 lying opposite one another.
Der Lineardämpfer ist als Fluiddämpfer ausgeführt. Es kann sowohl ein Luftdämpfer als auch ein Hydraulikdämpfer zum Einsatz kommen. The linear damper is designed as a fluid damper. Both an air damper and a hydraulic damper can be used.
