Description

Die Erfindung betrifft eine Hebevorrichtung für eine zweiflüglige Faltklappe oder-tür, die um waagerechte Achsen verschwenkbar ist. Die gattungsgemäße Hebevorrichtung besteht aus einem zweiarmigen Hebel, der um eine waagerechte Schwenkachse an einem seitlichen Korpusteil schwenkbar gelagert und dessen längerer Arm gelenkig mit dem unteren Flügel der Faltklappe oder -tür verbunden ist, und aus einem Druckelement, dessen eines Ende schwenkbar mit dem Korpusteil und dessen anderes Ende mit dem Hebel verbunden ist.The invention relates to a lifting device for a two-leaf folding flap or door, which is pivotable about horizontal axes. The generic lifting device consists of a two-armed lever, which is around a horizontal Swivel axis pivotally mounted on a side body part and the longer arm articulated to the lower wing of the folding flap or door is, and from a pressure element, whose one end pivotally connected to the body part and the other end is connected to the lever.

Bei einer aus der LU 55 310 bekannten Hebevorrichtung der vorgenannten Gattung besteht der längere Arm des zweiarmigen Hebels aus zwei relativ zueinander teleskopierbaren Teilen, so dass Längenänderungen des Hebelarms, die sich beim Öffnen oder Schließen der Faltklappe bzw. -tür ergeben, ausgeglichen und durch Betätigung des an der Vorderseite des unteren Flügels angebrachten Handgriffes derart kontrolliert werden können, dass der untere Flügel bei seiner Bewegung an die Stirnseite der seitlichen Korpusteile nicht anstößt. In a known from the LU 55 310 lifting device of the aforementioned type the longer arm of the two-armed lever consists of two relatively telescopic Divide so that changes in length of the lever arm, which occurs during Opening or closing the folding door or door result, balanced and through Operation of the handle attached to the front of the lower sash can be controlled so that the lower wing in its movement the front of the lateral body parts does not abut.

Bei der DE 201 00 662 U ist für eine Führung des unteren Flügels der zweiflügligen Faltklappe oder -tür längsverschieblich auf einer Schwenkachse der kürzere Hebelarm über ein Gleitstück oder eine Rolle in einer korpusfesten Kurvenführung geführt, um so sicherzustellen, dass dieser nicht gegen die Stirnflächen der Korpusteile anstößt.In DE 201 00 662 U is for a leadership of the lower wing of the two-winged Folding flap or door longitudinally displaceable on a pivot axis of the shorter lever arm via a slider or a roller in a corpus fixed curve guide guided so as to ensure that this is not against the end faces of the carcass parts abuts.

Aufgabe der vorliegenden Erfindung ist es, eine automatisch öffnende Hebevorrichtung für zweiflüglige Faltklappen der gattungsgemäßen Art derart weiterzubilden, dass sie kostengünstig durch Vermeidung von korpusfesten Kurvenführungen oder von teleskopierbaren Teilen herstellbar ist. Dabei ist zu berücksichtigen, dass bei automatischer Betätigung der Hebevorrichtung die Bewegung der Faltklappe bzw. -tür hier nicht aufgrund der Betätigung eines Handgriffes beeinflusst bzw. kontrolliert werden kann.The object of the present invention is an automatically opening lifting device for two-leaved folding flaps of the generic type in such a way, that they are cost effective by avoiding corpus fixed cam guides or can be produced by telescopic parts. It should be noted that during automatic operation of the lifting device, the movement of the folding flap or door here not influenced by the operation of a handle or can be controlled.

Erfindungsgemäß wird diese Aufgabe durch die Kombination der Merkmale des Anspruchs 1 gelöst. Ausgehend von einer gattungsgemäßen Hebevorrichtung ist der längere Hebelarm des zweiarmigen Hebels gelenkig und verschieblich mit dem unteren Flügel verbunden, wobei gleichzeitig dafür gesorgt ist, dass die Relativbewegung zwischen dem Anlenkpunkt des Hebels und dem unteren Flügel durch Feder- oder Reibungskraft gebremst wird. Bei dieser Lösung dient die Verschieblichkeit der Gelenkverbindung dazu, die sich während der Schwenkbewegung ergebende Längenänderung des Hebelarms auszugleichen. Eine solche Verbindung hat aber zwei Freiheitsgrade, so dass sie insgesamt instabil ist. Hier setzt der zweite Teil der Lösung ein, da diese Instabilität erfindungsgemäß aufgrund der Feder- bzw. Reibungskraft beseitigt wird. Die fehlende Bindung wird durch die Feder- bzw. Reibungskraft kompensiert, da die notwendige Längsverschieblichkeit in dem Führungslangloch erst nach Überwindung der Feder- bzw. Reibungskraft erfolgen kann. Der durch gebremste bzw. gedämpfte Anlenkpunkt bewirkt nun, dass der untere Flügel der Faltklappe bzw. -tür während der Öffnungsbewegung bzw. Schließbewegung von den Stirnseiten der seitlichen Korpusteile weggedrückt bzw. weggehalten wird. According to the invention, this object is achieved by the combination of the features of Claim 1 solved. Starting from a generic lifting device is the longer lever arm of the two-armed lever hinged and movable with the connected at the same time, while ensuring that the relative movement between the articulation point of the lever and the lower wing by spring or frictional force is slowed down. In this solution, the slidability serves the hinge connection, which results during the pivoting movement Compensate for change in length of the lever arm. Such a connection has but two degrees of freedom, so that it is unstable overall. Here is the second Part of the solution, since this instability according to the invention due to the spring or friction force is eliminated. The missing bond is caused by the spring or Frictional force compensated because the necessary longitudinal displacement in the guide slot take place after overcoming the spring or friction force can. The braked or damped pivot point now causes the lower wing of the folding flap or door during the opening movement or Closing movement pushed away from the end faces of the lateral body parts or is kept away.

Bevorzugte Ausführungsformen der Erfindung ergeben sich aus den sich an den Hauptanspruch anschließenden Unteransprüchen.Preferred embodiments of the invention will become apparent from the to the Main claim subsequent claims.

Demnach kann der längere Hebelarm des zweiarmigen Hebels und der untere Flügel der zweiflügligen Faltklappe oder -tür durch einen am längeren Hebelarm drehfest befestigten unrunden Bolzen miteinander verbunden sein, wobei der Bolzen drehbar und längsverschieblich in einer Langlochführung einer am unteren Flügel befestigten Tragplatte geführt ist.Thus, the longer lever arm of the two-armed lever and the lower wing the double-leaf folding flap or door by one on the longer lever arm non-rotatably mounted non-round bolts connected to each other, wherein the bolt rotatable and longitudinally displaceable in a slot guide one on the lower wing fixed support plate is guided.

Dabei kann der Bolzen zumindest über einen Teil seiner Länge oval sein. Gemäß einer anderen vorteilhaften Ausgestaltung kann der Bolzen zumindest über einen Teil seiner Länge rund mit sich gegenüberliegenden Abflachungen ausgeführt sein.In this case, the bolt may be oval over at least part of its length. According to According to another advantageous embodiment of the bolt, at least one Part of its length may be executed around with opposite flattenings.

Die Ränder der in der Tragplatte ausgenommenen Langlochführungen sind besonders vorteilhaft mit einem elastischen Kunststoff ausgekleidet. Die lichte Breite der Langlochführung entspricht in besonders vorteilhafter Weise dem schwarzen Durchmesser des Bolzens.The edges of the recessed in the support plate slot guides are special advantageously lined with an elastic plastic. The clear width of the Slot guide corresponds to the black in a particularly advantageous manner Diameter of the bolt.

Die Hebevorrichtung kann mittels eines Elektromotors antreibbar sein.The lifting device can be driven by means of an electric motor.

Weitere Einzelheiten und Vorteile ergeben sich aus dem in der Zeichnung dargestellten Ausführungsbeispiel.Further details and advantages will become apparent from the illustrated in the drawing Embodiment.

Aus Fig. 1 ist eine Seitenansicht eines Schrankes oder Schrank-/Kommodenelementes ersichtlich, dessen Öffnung durch eine aus zwei gelenkig miteinander verbundenen Flügeln 14 und 16 bestehende Faltklappe geschlossen und dessen vordere Seitenwand entfernt ist, um eine Hebevorrichtung 5 sichtbar zu machen. Die Hebevorrichtung 5 besteht, wie aus den Fig. 1 und 2 ersichtlich, im wesentlichen aus einem zweiarmigen Hebel 10, dessen kürzerer Arm gelenkig mit einem Elektromotor zum automatischen Hoch- und Runterschwenken verbunden ist. Der längere Arm 12 des zweiarmigen Hebels 10 ist in der Endstellung der Schwenkbewegung der Faltklappenelemente 14 und 16 unter Einschließen eines spitzen Winkels am unteren Flügel bzw. der unteren Faltklappe 16 angeschlossen. Damit verläuft der längere Arm 12 angenähert parallel zu dem unteren Flügel 16, so dass ein Bolzen bzw. Gelenkbolzen 18 frei verschieblich in einer langlochartigen Führung 20 einer am Flügel 16 befestigten Tragplatte 22 gehaltert ist. Der Elektromotor 24 kann daher ohne Schwierigkeiten die zweiflüglige Faltklappe in ihre Endstellung bringen, die jeweils von den Stirnseiten der seitlichen Korpusteile 26 und der geöffneten Stellung des oberen Falttürteils bzw. Flügels 14 begrenzt werden.From Fig. 1 is a side view of a cabinet or cabinet / commode element visible, its opening by one of two hinged interconnected wings 14 and 16 existing folding flap closed and its front side wall is removed to allow a lifting device 5 to be visible do. The lifting device 5 is, as shown in FIGS. 1 and 2, in the essential of a two-armed lever 10, whose shorter arm articulated with an electric motor for automatic up and down pivoting connected is. The longer arm 12 of the two-armed lever 10 is in the end position of Pivoting movement of the folding flap elements 14 and 16, including a acute angle connected to the lower wing or the lower folding flap 16. Thus, the longer arm 12 extends approximately parallel to the lower wing 16, so that a bolt or hinge pin 18 freely displaceable in a slot-like Guide 20 a mounted on the wing 16 support plate 22 is supported. The electric motor 24 can therefore easily the two-leaf folding flap in its final position bring, respectively from the end faces of the lateral body parts 26 and the open position of the upper folding door part or wing 14 are limited.

Bei der Bewegung der Faltklappe sind, wie in Fig. 3 dargestellt, verschiedene Bewegungsabläufe denkbar, die damit zusammenhängen, dass die Verbindung des zweiarmigen Hebels mit der Faltklappe zwei Freiheitsgrade hat und damit zu einer "labilen" Kenematik führt. In Fig. 3 ist der gewünschte Öffnungsweg, der aus den Faltklappenteilen 14 und 16 bestehenden Faltklappe in durchgezogener Linie gezeigt und eine andere unerwünschte Stellung der Faltklappe 1', 16' ist durch gestrichelte Linien dargestellt, wobei hier der untere Flügel 16' gegen den seitlichen Korpusteil 26 anstoßen würde.During the movement of the folding flap, as shown in Fig. 3, different movements conceivable, which are related to the connection of the two-armed lever with the folding flap has two degrees of freedom and thus to one "unstable" kenematics leads. In Fig. 3 is the desired opening path, which from the Faltklappenteilen 14 and 16 existing folding flap shown in a solid line and another undesired position of the folding flap 1 ', 16' is indicated by dashed lines Lines shown here, in which case the lower wing 16 'against the lateral body part 26 would kick off.

Um eine derartige Stellung zu verhindern, ist, wie in den Fig. 6 und 7 gezeigt, der Gelenkbolzen 18 vorgesehen.To prevent such a position, as shown in Figs. 6 and 7, the Hinge pin 18 is provided.

Der Gelenkbolzen 18 weist einen erweiterten, mittleren Teil 28 auf, der in eine komplementäre Ausnehmung 30 am vorderen Ende des längeren Arms 12 des zweiarmigen Hebels 10 drehfest gehalten ist. Beidseitig ist der Bolzen 18 mit gegenüberliegenden Abflachungen 32 versehen, deren Abstand der lichten Breite der an den Stegen der U-förmigen Tragplatte 22, die beispielhaft in Fig. 5 gezeigt ist, angeordneten langlochartigen Führung 20 entspricht, deren Ränder von einer elastischen Kunststoffauskleidung 34, z. B. einem Einsatz oder einer Dichtung, abgedeckt sind. Der Gelenkbolzen 18 weist weiterhin endseitige Nuten 36 für nichtgezeigte Sicherungsscheiben auf.The hinge pin 18 has an enlarged, central part 28 which in a complementary recess 30 at the front end of the longer arm 12 of the two-armed lever 10 is held against rotation. On both sides of the bolt 18 with opposite Flattened 32 provided whose distance to the clear width of the the webs of the U-shaped support plate 22, which is shown by way of example in Fig. 5, arranged slot-like guide 20 corresponds, the edges of an elastic Plastic lining 34, z. As an insert or a seal covered are. The hinge pin 18 further has end-side grooves 36 for not shown Lock washers on.

Der derart ausgestaltete Gelenkbolzen 18 ist in der in Fig. 5 dargestellten Führung 20 während der Bewegung der Faltklappe derart geneigt ausgerichtet, dass die Bewegung insgesamt gebremst wird, so dass aufgrund dieser in Folge Reibung induzierten Bremswirkung die Faltklappe während ihrer Bewegung die in der Fig. 3 mit durchgezogenen Linien dargestellte Öffnungs- bzw. Schließbewegung durchführt. Hierdurch wird ein störendes Anstoßen des unteren Faltklappen- bzw. Falttürteils 16 an die seitlichen Korpusteile 26 wirksam verhindert.The thus configured hinge pin 18 is in the guide shown in Fig. 5 20 aligned during the movement of the folding flap inclined so that the Movement is braked overall, so due to this in consequence friction induced folding effect the folding flap during their movement in FIG. 3 performs opening or closing movement shown by solid lines. As a result, a disturbing abutment of the lower Faltklappen- or Falttürteils 16 effectively prevents the lateral body parts 26.
