Description

Die Erfindung betrifft einen Beschlag zum schwenkbaren Befestigen einer nach oben zu öffnenden Frontklappe an einem Möbelschrank, mit einer an der Innenseite einer Schrank-Seitenwand zu befestigenden Montageplatte und einem an der Innenseite der Klappe zu befestigenden Halteteil, die über eine mindestens eine Kniehebelanordnung enthaltende Gelenkhebelanordnung mit zur Montageplatte rechtwinkeligen Gelenkachsen miteinander verbunden sind, derart, dass die dem Schrankkorpus vorgelagerte Frontklappe beim Öffnen eine sich vom Schrankkorpus abhebende Öffnungsbewegung mit im Raum wandernder Schwenkachse ausführt, wobei der Beschlag eine die Klappe in der Schließstellung haltende Federeinrichtung enthält.The invention relates to a fitting for pivotally attaching an upwardly opening front flap to a furniture cabinet, with a mounting plate to be fastened to the inside of a cabinet side wall and a holding part to be fastened to the inside of the flap, which has an articulated lever arrangement containing at least one toggle lever arrangement perpendicular to the mounting plate hinge axes are connected to each other, such that the front of the cabinet body front door opening when opening a contrasting cabinet body opening movement executes with in space pivot axis, wherein the fitting contains a flap in the closed position holding spring device.

Ein derartiger gattungsgemässer Beschlag ist aus der DE 296 16 978 U1 bekannt.Such a generic fitting is from the DE 296 16 978 U1 known.

Es handelt sich hier um einen Klappenbeschlag mit sieben Gelenkachsen, wobei die Hebelanordnung die Klappenbewegung so steuert, dass sich die in der Schließstellung der Stirnseite des Möbelkorpus vorgelagerte Klappe beim Öffnen von dieser Stirnseite abhebt, wonach die Klappe eine Schwenkbewegung um insgesamt mehr als 90° ausführen kann, wobei der Öffnungswinkel auch wesentlich größer als 90° sein und beispielsweise im Bereich von 135° liegen kann. Dabei lässt sich ohne weiteres außerdem erreichen, dass der in der Schließstellung oben liegende Klappenrand beim Öffnen und dementsprechend auch beim späteren Schließen nicht über die das hinter der Klappe befindliche Möbelfach oben begrenzende Schrank-Deckenwand nach oben hin vorsteht.This is a flap fitting with seven hinge axes, wherein the lever arrangement controls the flap movement so that the flap located in the closed position of the front side of the furniture carcass lifts when opening from this end, after which the flap perform a pivoting movement by a total of more than 90 ° can, wherein the opening angle also be substantially greater than 90 ° and, for example, may be in the range of 135 °. It goes without saying In addition, achieve that in the closed position overhead flap edge when opening and accordingly also during subsequent closing does not protrude above the located behind the flap furniture compartment above limiting cabinet ceiling wall upwards.

Bei dem bekannten Beschlag dient die Federeinrichtung nicht nur zum Zuhalten der Klappe in der Schließstellung sondern wirkt außerdem beim Öffnen dem Klappengewicht entgegen, so dass das Öffnen erleichtert wird. Die Federeinrichtung ist dementsprechend stark ausgelegt. Dies bringt mit sich, dass die Klappe beim Schließen, anschließend an einen Totpunkt, verhältnismäßig heftig gegen den Schrank gezogen wird, so dass die Klappe kraftvoll gegen den Schrank stößt, falls der Benutzer unachtsam ist oder die Klappe vorzeitig loslässt. Derartige Schläge sind unerwünscht.In the known fitting, the spring means not only serves to hold the flap in the closed position but also acts when opening the flap weight against, so that the opening is facilitated. The spring device is designed accordingly strong. This entails that the flap is relatively violently pulled against the cabinet when closing, then at a dead center, so that the flap powerfully pushes against the cabinet, if the user is careless or prematurely releases the flap. Such beats are undesirable.

EP1217159 beschreibt einen Beschlag mit einer Dämpfungseinrichtung, die gegen einen Arm einer Kniehebelanordnung anschlägt. EP1217159 describes a fitting with a damping device which abuts against an arm of a toggle lever assembly.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, einen Beschlag der eingangs genannten Art zu schaffen, bei dem das Auftreten von Schlägen beim Schließen der Klappe vermieden wird. Diese Aufgabe wird durch einen Beschlag gemäss Anspruch 1 gelöst.The present invention is therefore an object of the invention to provide a fitting of the type mentioned, in which the occurrence of shocks when closing the flap is avoided. This object is achieved by a fitting according to claim 1.

Auf diese Weise trifft der Dämpfungsanschlag vor Erreichen der Schließstellung auf die Dämpfungseinrichtung, so dass die ansonsten schnappend erfolgende Schließbewegung gedämpft wird. Durch entsprechendes Auslegen der Dämpfungseinrichtung erhält man ein sanftes Schließen.In this way, the damping stop strikes the damping device before reaching the closed position, so that the otherwise snapping closing movement is damped. By appropriate design of the damping device to obtain a gentle closing.

Erfindungsgemäss ist der Dämpfungsanschlag am Halteteil angeordnet . Weitere zweckmäßige Ausgestaltungen sind in den Unteransprüchen angegeben.According to the invention, the damping stop is arranged on the holding part. Further expedient refinements are specified in the subclaims.

Aus einem Vergleich der Figuren 1 und 2 bzw. 3 und 4 bzw. 5 und 6 ergibt sich, dass sich die an der Halteteil-Lagerpartie 9a; 9b; 9c angeordnete Gelenkachse 17a; 17b; 17c des ersten klappenseitigen Gelenkhebels 15a; 15b; 15c bei der Öffnungsbewegung der Klappe auf den mittleren Bereich des zweiten klappenseitigen Gelenkhebels 16a; 16b; 16c zu bewegt.From a comparison of FIGS. 1 and 2 or 3 and 4 or 5 and 6, it follows that the at the holding part bearing part 9a; 9b; 9c arranged hinge axis 17a; 17b; 17c of the first flap-side articulated lever 15a; 15b; 15c at the opening movement of the flap on the central region of the second flap-side articulated lever 16a; 16b; 16c to move.

Aus Platzgründen kann es günstig sein, dass der zweite klappenseitige Gelenkhebel 16a; 16b; 16c einen vom ersten klappenseitigen Gelenkhebel 15a; 15b; 15c weg ausgebauchten Verlauf aufweist.For reasons of space, it may be favorable for the second flap-side articulated lever 16a; 16b; 16c, a first flap-side pivot lever 15a; 15b; Has 15c away bulging course.

Bei allen Ausführungsbeispielen ist eine die Öffnungsbewegung der Klappe begrenzende Anschlageinrichtung 27a; 27b; 27c vorhanden, an der ein Hebel der Hebelanordnung bei der Öffnungsbewegung zur Anlage gelangt. Beim Ausführungsbeispiel nach den Figuren 3 und 4 befindet sich die Anschlageinrichtung 27b an einem der Hebel, und zwar an einem der beiden Einzelhebel der dort zusätzlich vorhandenen und nachstehend noch zu beschreibenden zweiten Kniehebelanordnung, wobei diese Anschlageinrichtung 27b von einer aus der Hebelebene hochgebogenen Anschlagzunge gebildet wird, die in der Offenstellung der Klappe am anderen Einzelhebel der zweiten Kniehebelanordnung zur Anlage gelangt.In all embodiments, an opening movement of the flap limiting stop means 27a; 27b; 27c present at which a lever of the lever assembly comes into contact with the opening movement. In the embodiment of the Figures 3 and 4 the stopper 27b is located on one of the levers, namely on one of the two individual levers of the second toggle lever arrangement additionally present there and to be described below, this stop means 27b being formed by a stop tongue bent up from the lever plane, which in the open position of the flap on another single lever of the second toggle lever arrangement comes to rest.

Bei den beiden anderen Ausführungsbeispielen ist die Anschlageinrichtung 27a; 27c an der Montageplatte 6a; 6c angeordnet. Dabei kann es sich wie beim Ausführungsbeispiel nach den Figuren 5 und 6, um ein von der Montageplatte 6c hochstehendes Bolzenstück handeln.In the other two embodiments, the stop means 27a; 27c on the mounting plate 6a; 6c arranged. It may, as in the embodiment according to the Figures 5 and 6 to act a bolt piece raised from the mounting plate 6c.

In Zusammenhang mit der Anschlageinrichtung kann vorgesehen sein, dass sie zum Verändern des von der Klappe in der Offenstellung eingenommenen Öffnungswinkels verstellbar ist. Dies ist bei dem Ausführungsbeispiel nach den Figuren 1 und 2 der Fall. Hier bildet der zweite wandseitige Gelenkhebel 12a - prinzipiell könnte es auch der erste wandseitige Gelenkhebel 11a sein - im Bereich seiner ihn an der Montageplatte 6a lagernden Gelenkachse 14a eine Anschlagnase 28. Dieser Anschlagnase 28 ist ein bewegbar an der Montageplatte 6a angeordnetes Anschlagglied 29 zugeordnet, das mehrere jeweils einem anderen Öffnungswinkel der Klappe zugeordnete Anschlagflächen 30 bildet, die jeweils durch entsprechendes Bewegen des Anschlaggliedes 29 in die Bewegungsbahn der Anschlagnase 28 beim Öffnen der Klappe überführbar sind. Beim Ausführungsbeispiel ist das Anschlagglied 29 mittels einer Schwenkachse 31 schwenkbar an der Montageplatte 6a angeordnet und weist an seiner der Anschlagnase 28 zugewandten Seite eine die Anschlagflächen 30 bildende Reihe von Anschlagausnehmungen auf. Diese geben der betreffenden Seite des Anschlagsglieds 29 ein sägezahnartiges Aussehen. Im dargestellten Falle ist das Anschlagglied 29 so weit verschwenkt, dass die den größten Öffnungswinkel zulassende Anschlagfläche 30 wirksam ist. Verschwenkt man das Anschlagglied 29 in Richtung gemäß Pfeil 32, gelangt je nach dem Schwenkwinkel eine der anderen Anschlagflächen 30 in die Bewegungsbahn der Anschlagnase 28, so dass der Öffnungswinkel der Klappe entsprechend kleiner wird. Zur Erleichterung der Handhabung kann das zweckmäßigerweise von einem Metallplättchen gebildete Anschlagglied 29 einen hochgebogenen Handgriff aufweisen.In connection with the stop device can be provided that it is adjustable for changing the occupied by the flap in the open position opening angle. This is in the embodiment of the FIGS. 1 and 2 the case. In this case, the second wall-side articulated lever 12a-in principle it could also be the first wall-side articulated lever 11a-has a stop lug 28 in the region of its articulation axis 14a supporting it on the mounting plate 6a. This stop lug 28 is associated with a stop member 29 arranged movably on the mounting plate 6a a plurality of each other a different opening angle of the flap associated abutment surfaces 30 forms, which can each be converted by corresponding movement of the stop member 29 in the movement path of the stop lug 28 when opening the flap. In the embodiment, the stop member 29 is pivotally mounted by means of a pivot axis 31 on the mounting plate 6a and has on its stop lug 28 side facing a stop surfaces 30 forming row of Anschlagausnehmungen. These give the relevant side of the stop member 29 a sawtooth appearance. In the illustrated case, the stop member 29 is pivoted so far that the largest opening angle permitting stop surface 30 is effective. If one pivots the stop member 29 in the direction indicated by arrow 32, depending on the pivot angle, one of the other stop surfaces 30 enters the path of movement of the stop lug 28, so that the opening angle of the flap is correspondingly smaller. To facilitate handling, the stop element 29 expediently formed by a metal plate may have a bent-up handle.

Der Beschlag enthält ferner eine die Klappe 2a; 2b; 2c in der Schließstellung und in der Offenstellung haltende Federeinrichtung, insbesondere eine Schraubenfeder 34a, 34b; 34c. Diese Federeinrichtung stützt sich einerseits an der Hebelanordnung und andererseits an der Montageplatte 6a; 6b; 6c ab.The fitting further includes a flap 2a; 2 B; 2c in the closed position and in the open position retaining spring device, in particular a coil spring 34a, 34b; 34c.

Bei der Ausführungsform nach den Figuren 1 und 2 ist die Schraubenfeder 34a einerseits im Bereich der den ersten klappenseitigen Gelenkhebel 15a mit dem zweiten wandseitigen Gelenkhebel 12a verbindenden Gelenkachse 20a an einem Federbefestigungsfortsatz 35 und andererseits an einer Federlagerstelle 36a der Montageplatte 6a festgelegt. Dabei ist an dem Federbefestigungsfortsatz 35 und an der Federlagerstelle 36a ein rechtwinkelig zur Montageplatte 6a gerichteter Zapfen oder dergleichen zum Einhängen der Schraubenfederenden angeordnet. Der Ort der Federlagerstelle 36a ist so gewählt, dass die Feder bei der Klappenbewegung in der Nähe der Schießstellung eine Totpunktlage durchläuft. Die Schraubenfeder 34a verläuft also in der Schließstellung der Klappe mit Bezug auf den zweiten wandseitigen Gelenkhebel 12a leicht geneigt im Sinne einer Zuhaltung. Beim Öffnen der Klappe schwenkt der zweite wandseitige Gelenkhebel 12a unter der Schraubenfeder 34a durch, so dass er relativ zur Schraubenfeder 34a in die mit Bezug auf die Schließstellung entgegengesetzte Richtung geneigt ist und in Öffnungsrichtung belastet wird. In der Totpunktlage liegt die an der Montageplatte 6a angeordnete Gelenkachse 14a des zweiten wandseitigen Gelenkhebels 12a auf der Mittellinie der Schraubenfeder 34a.In the embodiment of the FIGS. 1 and 2 is the coil spring 34a on the one hand in the region of the first flap-side pivot lever 15a with the second wall-side pivot lever 12a connecting hinge axis 20a fixed to a spring attachment extension 35 and on the other hand to a spring bearing point 36a of the mounting plate 6a. In this case, a right angle to the mounting plate 6a directed pin or the like for attaching the coil spring ends is arranged on the spring attachment extension 35 and on the spring bearing 36a. The location of the spring bearing 36a is chosen so that the spring undergoes a dead center position in the flap movement in the vicinity of the firing position. The coil spring 34a thus extends in the closed position of the flap with respect to the second wall-side pivot lever 12a slightly inclined in the sense of a tumbler. When opening the flap, the second wall-side pivot lever 12a pivots under the coil spring 34a, so that it is inclined relative to the coil spring 34a in the opposite direction with respect to the closed position and is loaded in the opening direction. In the dead center position arranged on the mounting plate 6a hinge axis 14a of the second wall-side pivot lever 12a is located on the center line of the coil spring 34a.

Diese Kniehebelanordnung 37c nimmt bei geöffneter Klappe 2c eine mit Bezug auf den ersten klappenseitigen Gelenkhebel 15c stärker geneigte Strecklage ein. Die Federlagerstelle 36c befindet sich bei diesem Ausführungsbeispiel vorne unten an der Montageplatte 6c. Dabei kann die Federlagerstelle 36c etwa in Höhe der die zweite Kniehebelanordnung 37 mit der Montageplatte 6c verbindenden Gelenkachse 41c und etwa in der Tiefe der den ersten wandseitigen Gelenkhebel 11c mit der Montageplatte 6c verbindenden Gelenkachse 13c angeordnet sein.In the case of the embodiment according to the Figures 5 and 6 is the hinge axis 41c connecting the second toggle lever arrangement 37c to the mounting plate 6c below the hinge axis 14c connecting the second wall-side pivot lever 12c to the mounting plate 6c and being approximately at the same depth as the latter, ie approximately equidistant from the cabinet end face, wherein the second toggle lever assembly 37c is buckled rearwardly. When the flap 2c is open, this toggle lever arrangement 37c assumes an extended position that is more inclined with respect to the first flap-side pivot lever 15c. The spring bearing 36c is located in this embodiment front lower on the mounting plate 6c. In this case, the spring bearing point 36c can be approximately at the level of the joint axis 41c connecting the second toggle lever arrangement 37 with the mounting plate 6c and approximately at the depth of the first one wall-side articulated lever 11c be arranged with the mounting plate 6c connecting hinge axis 13c.

Mit Hilfe der zweiten Kniehebelanordnung 37b; 37c erhält man eine besonders gute Umsetzung der Kraft der Schraubenfeder 34b; 34c. In diesem Zusammenhang ist es zweckmäßig, wie es beim Ausführungsbeispiel nach den Figuren 5 und 6 der Fall ist, dass der der zweiten Kniehebelanordnung 37c zugewandte Hebelarm 24c des ersten klappenseitigen Gelenkhebels 15c verlängert ist. Daher ist bei diesem Ausführungsbeispiel im Unterschied zum Ausführungsbeispiel nach den Figuren 3 und 4 dieser Hebelarm 24c länger als der klappenseitige Hebelarm 26c des ersten klappenseitigen Gelenkhebels 15c.With the help of the second toggle lever arrangement 37b; 37c gives a particularly good implementation of the force of the coil spring 34b; 34c. In this context, it is expedient, as in the embodiment of the Figures 5 and 6 the case is that of the second toggle lever assembly 37c facing lever arm 24c of the first flap-side articulated lever 15c is extended. Therefore, in this embodiment, in contrast to the embodiment of the Figures 3 and 4 this lever arm 24c longer than the flap-side lever arm 26c of the first flap-side articulated lever 15c.

Beim Schließen der Klappe wirkt auf die Klappe nach Überwindung des Totpunktes eine Schließkraft ein. Damit dies nicht zu unerwünschten Schlägen und Stößen führt, wird die Schließbewegung gedämpft, indem vorzugsweise an der Montageplatte 6a; 6b; 6c eine fluidische Dämpfungseinrichtung 50a; 50b; 50c und an dem Halteteil (7a, 7b, 7c) ein der Dämpfungseinrichtung 50a; 50b; 50c zugeordneter und beim Schließen der Klappe 2a; 2b; 2c gegen die Dämpfungseinrichtung 50a; 50b; 50c laufender Dämpfungsanschlag 51a; 51b; 51c angeordnet ist. Die Dämpfungseinrichtung 50a; 50b, 50c kann mit Luft oder einer Flüssigkeit betrieben werden. Zweckmäßigerweise handelt es sich um einen Dämpfungszylinder beispielsweise in Gestalt einer Gasdruckfeder, eines Öldruckdämpfers oder eines Rotationsdämpfers.When closing the flap acts on the flap after overcoming the dead center a closing force. So that this does not lead to unwanted shocks and bumps, the closing movement is damped by preferably on the mounting plate 6a; 6b; 6c, a fluidic damping device 50a; 50b; 50c and on the holding part (7a, 7b, 7c) one of the damping device 50a; 50b; 50c assigned and when closing the flap 2a; 2 B; 2c against the damping device 50a; 50b; 50c running damping stop 51a; 51b; 51c is arranged. The damping device 50a; 50b, 50c can be operated with air or a liquid. Appropriately, it is a damping cylinder, for example in the form of a gas spring, an oil pressure damper or a rotary damper.

Die Dämpfungseinrichtung 50a; 50b, 50c ist fest an der Montageplatte 6a; 6b; 6c montiert und kann an einer an die Montageplatte geschraubten Befestigungsplatte 52a; 52b; 52c angeordnet sein. Die dargestellte Dämpfungseinrichtung 50a; 50b; 50c weist ein aus ihr nach Art einer Kolbenstange vorstehendes Betätigungsteil 53a; 53b; 53c auf, das normalerweise ausgefahren ist (Figuren 2, 4 und 6) und beim Schließen vom Dämpfungsanschlag 51a; 51b; 51c entgegen der Dämpfungskraft nach innen gedrückt wird. Öffnet man die Klappe 2a; 2b; 2c dann wieder, fährt das Betätigungsteil 53a; 53b; 53c selbsttätig aus.The damping device 50a; 50b, 50c is fixed to the mounting plate 6a; 6b; 6c mounted and can be attached to a screwed to the mounting plate mounting plate 52a; 52b; 52c may be arranged. The illustrated damping device 50a; 50b; 50c has a protruding from it in the manner of a piston rod Operating part 53a; 53b; 53c, which is normally extended ( Figures 2 . 4 and 6 ) and closing the damping stop 51a; 51b; 51c against the damping force is pressed inwards. If you open the flap 2a; 2 B; 2c again, the operating part 53a drives; 53b; 53c automatically off.

Die Dämpfungseinrichtung 50a; 50b; 50c und der Dämpfungsanschlag 51a; 51b; 51c werden so positioniert, dass der Dämpfungsanschlag gegen die Stirnseite des Betätigungsteils 53a; 53b; 53c trifft.The damping device 50a; 50b; 50c and the damping stop 51a; 51b; 51c are positioned so that the damping abutment against the end face of the operating part 53a; 53b; 53c meets.

Der erste wandseitige Gelenkhebel 11a; 11b; 11c und der zweite klappenseitige Gelenkhebel 16a; 16b; 16c bilden, wie oben ausführlich beschrieben, eine Kniehebelanordnung. Beide Hebel führen beim Schließen eine in das Innere des Möbelkorpus gerichtete Bewegung aus, wobei sie sich gleichzeitig sozusagen zusammenklappen.The first wall-side articulated lever 11a; 11b; 11c and the second flap-side pivot lever 16a; 16b; 16c, as described in detail above, form a toggle assembly. Both levers perform when closing a directed into the interior of the furniture body movement, while they collapse, so to speak.

Wie bereits erwähnt, ist der erste wandseitige Gelenkhebel 11a; 11b; 11c in einer ersten Ebene und sind die beiden klappenseitigen Gelenkhebel 15a, 16a; 15b, 16b; 15c, 16c in einer zweiten Ebene angeordnet.As already mentioned, the first wall-side articulated lever 11a; 11b; 11c in a first plane and are the two flap-side toggle levers 15a, 16a; 15b, 16b; 15c, 16c arranged in a second plane.
