Description

Stellmechanismus zum Bewegen einer hochbewegbaren Klappe eins Möbels Actuation mechanism for moving a highly movable flap of a piece of furniture
Die vorliegende Erfindung bezieht sich auf einen Stellmechanismus zum Bewegen einer hochbewegbaren Klappe eines Möbels, mit einem an einem Möbelkorpus zu befestigenden Grundkörper, wobei ein Stellarm zum Bewegen der Klappe einerseits an einer Lagerachse des Grundkörpers und andererseits an einer Lagerachse an einem an der Klappe zu befestigenden Beschlagteil gelagert ist und wobei ein zusätzlicherThe present invention relates to an adjusting mechanism for moving a highly movable flap of a piece of furniture, to be fastened to a furniture body body, wherein an actuating arm for moving the flap on the one hand to a bearing axis of the body and on the other hand to a bearing axis to be fastened to the flap Fitting part is stored and where an additional
Steuerarm zum Bewegen der Klappe vorgesehen ist, wobei während der Bewegung des Stellarmes die effektive Hebelarmlänge des Steuerarmes veränderlich ist.Control arm is provided for moving the flap, wherein during the movement of the actuating arm, the effective lever arm length of the control arm is variable.
Im Weiteren betrifft die Erfindung ein Möbel mit einem Stellmechanismus der zu beschreibenden Art, der zum Bewegen einer hoch bewegbaren Klappe vorgesehen ist.Furthermore, the invention relates to a piece of furniture with an adjusting mechanism of the type to be described, which is provided for moving a highly movable flap.
Derartige Stellmechanismen werden zum Bewegen von Möbelklappen verwendet, die zwischen einer ein Schrankfach in einem Möbelkorpus verschließenden vertikalen Stellung und einer nach oben bewegten Offenstellung verstellbar gelagert sind. Beim Öffnen der Klappe kommt es mitunter zu einer beträchtlichen Abhebebewegung in Bezug zur Stirnseite des Möbelkorpus, was für den Benutzer als unangenehm empfunden wird, da einerseits relativ viel Freiraum vorgesehen werden muss und andererseits zudem die Gefahr besteht, dass der vor dem Schrankkorpus befindliche Benutzer durch ein übermäßiges Ausschwenken der Klappe Verletzungen am Kopf erleiden kann. Der Benutzer wird deshalb beim Öffnen der Klappe intuitiv nach hinten ausweichen, wenn sich die Klappe in der Höhe des Kopfes bewegt.Such adjusting mechanisms are used for moving furniture flaps, which are adjustably mounted between a cabinet compartment in a furniture body closing vertical position and an upwardly moved open position. When opening the door, there is sometimes a considerable lifting movement in relation to the front side of the furniture body, which is perceived as unpleasant for the user, since on the one hand relatively much space must be provided and on the other hand there is a risk that the user located in front of the cabinet body by Excessive swinging of the flap can cause injury to the head. The user will therefore intuitively back out when opening the flap when the flap moves at the height of the head.
Aus der EP 0 952 290 A2 und der EP 1 785 565 A2 sind Klappenbeschläge für nach oben zu öffnende Möbelklappen bekannt geworden, wobei ein federbeaufschlagter Stellarm und ein Steuermechanismus in Form von zwei miteinander gelenkig verbundenen Gelenkhebeln vorgesehen sind, deren effektive Hebelarmlänge bei der Öffnungsbewegung der Klappe vergrößert wird. Nachteilig daran ist die Gefahr, dass die Möbelklappe im Zuge der Öffnungsbewegung leicht mit dem Kopf des Benutzers kollidieren kann. Aufgabe der vorliegenden Erfindung ist es daher, einen Stellmechanismus der eingangs erwähnten Gattung mit einer verbesserten Kinematik zur weitgehenden Vermeidung oben genannter Nachteile anzugeben.From EP 0 952 290 A2 and EP 1 785 565 A2 flap fittings for upwardly opening furniture flaps have become known, wherein a spring-loaded actuator arm and a control mechanism in the form of two hingedly connected articulated levers are provided whose effective Hebelarmlänge during the opening movement of Flap is enlarged. The disadvantage of this is the risk that the furniture flap in the course of the opening movement can easily collide with the head of the user. Object of the present invention is therefore to provide an actuating mechanism of the type mentioned with an improved kinematics to largely avoid the above-mentioned disadvantages.
Dies wird erfindungsgemäß in einer vorteilhaften Ausgestaltung dadurch erreicht, dass sich die effektive Hebelarmlänge des Steuerarmes beim Öffnen des Stellarmes verkürzt.This is inventively achieved in an advantageous embodiment that shortens the effective lever arm length of the control arm when opening the actuator arm.
Der Grundgedanke der vorliegenden Erfindung besteht also darin, die vom Steuerarm gebildete effektive Hebelarmlänge bei der Öffnungsbewegung der Klappe zu verkürzen. Die effektive Hebelarmlänge des Steuerarmes kann dabei als Funktion des Drehwinkels des die Bewegung der Klappe kräftemäßig unterstützenden Stellarmes gestaltet werden. In diesem Zusammenhang kann insbesondere ein nichtlinearer Verlauf vorgesehen werden, nämlich, dass sich die effektive Hebelarmlänge des Steuerarmes in einem ersten - an die Schließstellung anschließenden Öffnungswinkelbereich des Stellarmes weniger ändert, als in einem daran anschließenden zweiten Öffnungswinkelbereich, der bis zur vollständigen Offenstellung des Stellarmes hin reicht.The basic idea of the present invention is thus to shorten the effective lever arm length formed by the control arm during the opening movement of the flap. The effective lever arm length of the control arm can be designed as a function of the angle of rotation of the movement of the flap force-moderately supporting actuator arm. In this context, in particular a non-linear course can be provided, namely that the effective lever arm length of the control arm changes less in a first opening angle range of the actuating arm adjoining the closed position than in a subsequent second opening angle range until the fully open position of the actuating arm enough.
Auf diese Weise ist es beispielsweise möglich, die Klappe in einem von der vollständigen Schließstellung ausgehenden ersten Schwenkbereich parallel zu sich selbst (d.h. im Wesentlichen parallel zur Stirnseite des Möbelkorpus) zu bewegen und anschließend über den Möbelkorpus hinweg zu klappen, wobei die Klappe in einem der vollständigen Offenstellung unmittelbar vorgelagerten Bereich durch eine relativ stark ausgeprägte Längenänderung des Steuerarmes eine entsprechend starke Verschwenkbewegung durchläuft.In this way it is possible, for example, to move the flap parallel to itself (ie substantially parallel to the front side of the furniture body) in a first pivoting area extending from the complete closed position and then to fold over the furniture body, the flap in one of the full open position immediately upstream region by a relatively pronounced change in length of the control arm undergoes a correspondingly strong pivoting movement.
Durch die vorgeschlagene Konstruktion kann einerseits die Abhebebewegung der Klappe in Bezug zur Stirnseite des Möbelkorpus gering gehalten werden, andererseits ist es dadurch auch möglich, dass die Klappe durch eine entsprechend starke Verschwenkbewegung in dem der vollständigen Offenstellung unmittelbar vorgelagerten Bereich nicht die maximale Raumhöhe erreicht, sodass die Klappe in ihrer Offenstellung für den Benutzer noch leicht zu betätigen ist. Ein weiterer Vorteil liegt auch darin, dass bei motorisch angetriebener Klappe - insbesondere bei der Schließbewegung - die Gefahr reduziert wird, dass die untere Kante der Klappe den Benutzer am Kopf trifft. Der Steuerarm ist einerseits drehgelenkig an einer korpusseitigen Lagerachse am Möbelkorpus und andererseits drehgelenkig mit der Klappe verbunden. Die Erfindung sieht nunmehr vor, den relativen Abstand zwischen der korpusseitigen Lagerachse des Steuerarmes und der klappenseitigen Lagerachse des Steuerarmes im Zuge der Verschwenkbewegung des Stellarmes zu verändern, vorzugsweise zu verkürzen.Due to the proposed construction, on the one hand the lift-off movement of the flap relative to the front side of the furniture body can be kept low, on the other hand, it is also possible that the flap does not reach the maximum ceiling height by a correspondingly strong pivoting movement in the region immediately above the fully open position the flap is still easy to operate in its open position for the user. Another advantage lies in the fact that with motor-driven flap - especially during the closing movement - the risk is reduced that the lower edge of the flap hits the user on the head. The control arm is on the one hand pivotally connected to a body side bearing axis on the furniture body and on the other hand pivotally connected to the flap. The invention now provides to change the relative distance between the body-side bearing axis of the control arm and the flap-side bearing axis of the control arm in the course of the pivoting movement of the actuating arm, preferably to shorten.
Konstruktiv kann die Ausgestaltung so getroffen sein, dass der Steuerarm wenigstens zwei relativ zueinander bewegbare Teile aufweist. Hierbei ist die relative Bewegbarkeit so zu verstehen, dass alle Lagermöglichkeiten der wenigstens zwei Teile zueinander umfasst sind, die eine Verkürzung des Abstandes der korpusseitigen und der klappenseitigen Lagerachse des Steuerarmes während der Verschwenkbewegung der Klappe herbeiführen können.Structurally, the design can be made such that the control arm has at least two parts that are movable relative to one another. Here, the relative mobility is to be understood that all storage options of at least two parts are included to each other, which can bring about a shortening of the distance of the body side and the flap side bearing axis of the control arm during the pivoting movement of the flap.
Bei einem möglichen Ausführungsbeispiel der Erfindung kann vorgesehen sein, dass die wenigstens zwei Teile über eine Gelenkachse miteinander verbunden sind, wobei ein zusätzlicher Zwischenhebel vorgesehen ist, der zwischen der Gelenkachse der wenigstens zwei Teile und einer Gelenkachse am Stellarm wirksam ist. Der zusätzliche Zwischenhebel übernimmt hierbei die Funktion einer Zwangssteuerung, durch den die beiden miteinander gelenkig verbundenen Hebelteile während der Öffnungsbewegung des Stellarmes geknickt werden. Hierbei werden die Hebelteile - ausgehend von der vollständigen Schließstellung des Stellarmes - anfänglich nur geringfügig abgewinkelt, in einem zweiten Schwenkbereich bis hin zur vollständigen Offenstellung des Stellarmes jedoch relativ stark geknickt, wodurch der gewünschte Öffnungsverlauf der Klappe realisiert werden kann.In a possible embodiment of the invention can be provided that the at least two parts are connected to each other via a hinge axis, wherein an additional intermediate lever is provided which is effective between the hinge axis of the at least two parts and a hinge axis on the actuator arm. The additional intermediate lever assumes the function of a positive control, by which the two articulated lever parts hinged together during the opening movement of the actuating arm. Here, the lever parts - starting from the complete closed position of the actuating arm - initially only slightly angled, but in a second pivoting range up to the full open position of the actuating arm relatively strong kinked, whereby the desired opening course of the flap can be realized.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung kann vorgesehen sein, dass die relative Lage der wenigstens zwei Teile zueinander durch eineAccording to a further embodiment of the invention can be provided that the relative position of the at least two parts to each other by a
Antriebsvorrichtung, vorzugsweise durch einen elektrischen Antrieb, veränderbar ist.Drive device, preferably by an electric drive, is variable.
Bei einer zweckmäßigen Weiterbildung der Erfindung kann vorgesehen sein, dass der elektrische Antrieb über einen Übertragungsmechanismus eine Verstellung der relativen Lage der wenigstens zwei Teile zueinander herbeiführt. Hierbei kann der elektrische Antrieb zur Veränderung des Abstandes zwischen der korpusseitigen Lagerachse und der klappenseitigen Lagerachse des Steuerarmes so angesteuert werden, dass der elektrische Antrieb in einem ersten Drehwinkelbereich des Stellarmes, ausgehend von dessen vollständiger Schließstellung, entweder gar nicht oder nur geringfügig bewegt wird, während in einem der vollständigen Offenstellung des Stellarmes unmittelbar vorgelagerten Öffnungswinkelbereich des Stellarmes eine stärker ausgeprägte relative Verkürzung des Steuerarmes vorgenommen wird.In an expedient development of the invention can be provided that the electric drive via a transmission mechanism causes an adjustment of the relative position of the at least two parts to each other. Here, the electric drive for changing the distance between the body side Bearing axis and the flap-side bearing axis of the control arm are controlled so that the electric drive in a first rotation angle range of the actuating arm, starting from the full closed position, either not or only slightly moved, while in one of the fully open position of the actuating arm immediately preceding opening angle range of the actuating arm a more pronounced relative shortening of the control arm is made.
Gemäß einer ersten Variante der Erfindung kann der Steuerarm eine korpusseitige Lagerachse aufweisen, die an oder in einem Grundkörper des Stellmechanismus angeordnet ist. Alternativ kann die Lagerachse des Steuerarmes auch an einem vom Grundkörper des Stellmechanismus gesonderten Lagerteil am Möbel angeordnet werden. Hierbei kann die korpusseitige Lagerachse des Steuerarmes im obersten Bereich des Möbelkorpus und vorzugsweise im Bereich der Stirnseite des Möbelkorpus angeordnet werden. Die korpusseitige Lagerachse und die klappenseitige Lagerachse des Stellarmes bilden somit mit der korpusseitigen Lagerachse und der klappenseitigen Lagerachse des Steuerarmes ein Gelenkviereck, wobei durch eine Anordnung der korpusseitigen Lagerachse im obersten und vordersten Bereich des Möbelkorpus die vom Gelenkviereck gebildete Fläche vergrößerbar ist, wodurch sich günstige Hebelverhältnisse zum Bewegen der Klappe realisieren lassen.According to a first variant of the invention, the control arm may have a body-side bearing axis, which is arranged on or in a base body of the adjusting mechanism. Alternatively, the bearing axis of the control arm can also be arranged on a separate from the main body of the actuating mechanism bearing part on the furniture. In this case, the body-side bearing axis of the control arm can be arranged in the uppermost region of the furniture body and preferably in the region of the front side of the furniture body. The body-side bearing axis and the flap-side bearing axis of the actuating arm thus form a four-bar linkage with the body side bearing axis and the flap side bearing axis of the control arm, which can be increased by an arrangement of the body side bearing axis in the top and foremost area of the furniture body, the surface formed by the four-bar linkage, resulting in favorable leverage to move the flap.

Fig. 6 ein Diagramm des Kurvenverlaufs der effektiven Hebelarmlänge des Steuerarmes als Funktion des Öffnungswinkels des Stellarmes. Fig. 1 zeigt eine perspektivische Darstellung eines an einer Wand 2 befestigten schrankförmigen Möbels, das insbesondere als Küchenoberschrank Verwendung findet. Das Möbel 1 umfasst einen an der Wand 2 zu befestigenden Möbelkorpus 3, an dessen Seitenwand ein erfindungsgemäßer Stellmechanismus 5 zum Verstellen einer hochbewegbaren Klappe 4 montiert ist. Die Klappe 4 nimmt in der Schließstellung eine im Wesentlichen vertikale Position ein und ist ausgehend von dieser vertikalen Stellung in eine nach oben verstellte Offenstellung bewegbar. Aus Gründen der Übersichtlichkeit ist nur ein Teil der Klappe 4 und des Möbelkorpus 3 dargestellt. An der Innenseite der gegenüberliegenden Seitenwand des Möbels 1 kann ebenfalls ein Stellmechanismus 5 angeordnet werden. Der Stellmechanismus 5 weist einen Stellarm 6 auf, der von einer nicht näher dargestellten Antriebsvorrichtung (Federvorrichtung und/oder Elektromotor) beaufschlagbar ist. Der Stellarm 6 unterstützt daher kräftemäßig die Bewegung der Klappe 4. Zusätzlich zum Stellarm 6 ist ein Steuerarm 7 vorgesehen, der die Bewegungscharakteristik der Klappe 4 während ihres Bewegungsweges beeinflusst. Während des Öffnungsverlaufes der Klappe 4 kann es bei herkömmlichen Lösungen zu einer beträchtlichen Abhebebewegung der Klappe 4 in Bezug zur Stirnseite des Möbelkorpus 3 kommen, durch die der Benutzer Gefahr läuft, sich zu verletzen. Die Erfindung schlägt nunmehr vor, die effektive Hebelarmlänge des Steuerarmes 7 während des Öffnungsverlaufes der Klappe 4 zu verkürzen, was durch den Zwischenhebel 8 herbeigeführt wird. Der Zwischenhebel 8 ist zwischen dem Stellarm 6 und dem Steuerarm 7 wirksam, sodass hierdurch eine Zwangsverstellung des Steuerarmes 7 realisiert wird, so wie dies in den nachfolgenden Figuren noch näher zu beschreiben ist.Fig. 6 is a diagram of the curve of the effective lever arm length of the control arm as a function of the opening angle of the actuating arm. Fig. 1 shows a perspective view of a wall-mounted on a cabinet 2 cabinet-shaped furniture, which is used in particular as a kitchen cupboard. The furniture 1 comprises a furniture body 3 to be fastened to the wall 2, on the side wall of which an adjusting mechanism 5 according to the invention for adjusting a highly movable flap 4 is mounted. The flap 4 assumes a substantially vertical position in the closed position and is movable starting from this vertical position into an upwardly adjusted open position. For clarity, only a part of the flap 4 and the furniture body 3 is shown. On the inside of the opposite side wall of the furniture 1, an adjusting mechanism 5 can also be arranged. The adjusting mechanism 5 has an actuating arm 6, which can be acted upon by a drive device (spring device and / or electric motor) not shown in detail. The actuating arm 6 therefore supports the movement of the flap 4 in terms of power. In addition to the actuating arm 6, a control arm 7 is provided which influences the movement characteristic of the flap 4 during its movement path. During the course of the opening of the flap 4, in conventional solutions, a considerable lift-off movement of the flap 4 with respect to the front side of the furniture body 3 can occur, through which the user runs the risk of injuring himself. The invention now proposes to shorten the effective lever arm length of the control arm 7 during the opening course of the flap 4, which is brought about by the intermediate lever 8. The intermediate lever 8 is effective between the actuator arm 6 and the control arm 7, so that thereby a forced adjustment of the control arm 7 is realized, as will be described in more detail in the following figures.
Fig. 2 zeigt die Anordnung gemäß Fig. 1 in einer Seitenansicht. An wenigstens einer Seitenwand des Möbelkorpus 3 ist ein Stellmechanismus 5 montiert, der eine nicht näher dargestellte Antriebsvorrichtung (Federvorrichtung und/oder Elektromotor) zum Beaufschlagen des Stellarmes 6 umfasst. Der Stellarm 6 ist korpusseitig an oder in einem Grundkörper 5a an einer Lagerachse A angeordnet, das andere distale Ende des Stellarmes 6 ist am klappenseitigen Beschlagteil 9 an einer Lagerachse B drehgelenkig befestigt. Zusätzlich zum Stellarm 6 ist ein Steuerarm 7 vorgesehen, der im gezeigten Ausführungsbeispiel zwei an der Gelenkachse F miteinander gelenkig verbundene Teile 7a und 7b umfasst. Der Steuerarm 7 mit den zwei Teilen 7a, 7b lagert also korpusseitig an der Lagerachse C und klappenseitig am Beschlagteil 9 an der Lagerachse D. Ein vorzugsweise gekröpfter Zwischenhebel 8 verbindet den Stellarm 6 an der Gelenkachse E mit dem Stellarm 7 an der Gelenkachse F. Ausgehend von der vollständigen Schließstellung der Klappe 4 werden die beiden Teile 7a, 7b des Steuerarmes 7 nur unwesentlich geknickt, wodurch eine im Wesentlichen parallele Führung der Klappe in Bezug zur Stirnseite des Möbelkorpus 3 möglich ist. Ab einem bestimmten Schwenkwinkel des Stellarmes 6 (beispielsweise ab 70° in Bezug zur Vertikalen) erfolgt durch den Zwischenhebel 8 eine stärker ausgeprägte Knickung der beiden Teile 7a, 7b, wodurch die Klappe 4 eine entsprechend starke Verschwenkbewegung ausführt und über den Möbelkorpus 3 hinweg nach hinten verschwenkbar ist.Fig. 2 shows the arrangement of FIG. 1 in a side view. On at least one side wall of the furniture body 3, an adjusting mechanism 5 is mounted, which comprises a non-illustrated drive device (spring device and / or electric motor) for acting on the actuating arm 6. The actuating arm 6 is arranged on the body side on or in a base body 5a on a bearing axis A, the other distal end of the actuating arm 6 is pivotally attached to the flap-side fitting part 9 on a bearing axis B. In addition to the actuating arm 6, a control arm 7 is provided which, in the exemplary embodiment shown, comprises two parts 7a and 7b articulated to one another on the articulation axis F. The control arm 7 with the two parts 7a, 7b thus superimposed on the body side of the bearing axis C and on the flap side on the fitting part 9 A preferably cranked intermediate lever 8 connects the actuator arm 6 on the hinge axis E with the actuating arm 7 on the hinge axis F. Starting from the complete closed position of the flap 4, the two parts 7a, 7b of the control arm 7 are only slightly folded, creating a essentially parallel guidance of the flap with respect to the front side of the furniture body 3 is possible. From a certain pivoting angle of the actuating arm 6 (for example, from 70 ° with respect to the vertical) is carried out by the intermediate lever 8 a more pronounced buckling of the two parts 7a, 7b, whereby the flap 4 performs a correspondingly strong pivoting movement and over the furniture body 3 away to the rear is pivotable.
Fig. 3a bis Fig. 3d zeigen den Öffnungsverlauf der Klappe 4 in zeitlichen Abfolgen. In Fig. 3a ist die Klappe 4 in der vollständigen Schließstellung dargestellt. An einer Seitenwand des Möbelkorpus 3 ist der Stellmechanismus 5 mit seinem die Bewegung der Klappe 4 unterstützenden Stellarm 6 befestigt. Vom Steuerarm 7 ist der Teil 7b erkennbar, der an der Lagerachse D des klappenseitigen Beschlagteiles 9 drehgelenkig angeordnet ist. Mit dem Bezugszeichen C ist die korpusseitige Lagerachse des Steuerarmes 7 gekennzeichnet, die entweder am Grundkörper 5a des Stellmechanismus 5 oder auch davon gesondert am Möbelkorpus 3 anordenbar ist. Von Bedeutung ist der in Fig. 5b eingezeichnete relative Abstand S der beiden Lagerachsen C und D des Steuerarmes 7, der im Zuge des Öffnungsvorganges der Klappe 4 verkleinerbar ist.3 a to 3d show the course of the opening of the flap 4 in time sequences. In Fig. 3a, the flap 4 is shown in the fully closed position. On a side wall of the furniture body 3 of the adjusting mechanism 5 is fixed with its the movement of the flap 4 assisting actuator 6. From the control arm 7 of the part 7b can be seen, which is pivotally mounted on the bearing axis D of the valve-side fitting part 9. With the reference numeral C, the body-side bearing axis of the control arm 7 is marked, which can be arranged either on the main body 5a of the actuating mechanism 5 or separately thereof on the furniture body 3. Of importance is drawn in Fig. 5b relative distance S of the two bearing axes C and D of the control arm 7, which is reduced in size in the course of the opening operation of the flap 4.
Fig. 3b zeigt die Klappe 4 in einer leichten Offenstellung, wobei die Klappe 4 in einem ersten Schwenkbereich im Wesentlichen parallel zu sich selbst bewegebar ist und eine vom Möbelkorpus 3 abhebende Bewegung ausführt. Der an der Gelenkachse E am3b shows the flap 4 in a slight open position, wherein the flap 4 is bewegebar in a first pivoting area substantially parallel to itself and performs a contrasting furniture body 3 movement. The at the joint axis E am
Stellarm 6 angeordnete Zwischenhebel 8 verursacht in diesem ersten Schwenkbereich der Klappe 4 nur eine unwesentliche Knickung der beiden Teile 7a, 7b desAdjusting arm 6 arranged intermediate lever 8 causes in this first pivoting range of the flap 4 only an insignificant buckling of the two parts 7a, 7b of the
Steuerarmes 7. Mit dem Bezugszeichen S ist der relative Abstand (Normalabstand) der beiden Lagerachsen C und D des Steuerarmes 7 gekennzeichnet. Darüber hinaus kann auf die Lagerachse A des Stellarmes 6 am Grundkörper 5a auch ein schematisch dargestellter Elektromotor 12 wirksam sein.Control arm 7. The reference symbol S denotes the relative distance (normal distance) of the two bearing shafts C and D of the control arm 7. In addition, a schematically illustrated electric motor 12 can be effective on the bearing axis A of the actuating arm 6 on the main body 5a.
Fig. 3c zeigt eine von Fig. 3b weitergeführte Bewegung der Klappe 4, die beiden Teile 7a, 7b des Steuerarmes 7 wurden zwar durch den Zwischenhebel 8 etwas stärker geknickt, dennoch ergibt sich daraus im Vergleich zur Fig. 3b nur eine unwesentliche Änderung des Abstandes S zwischen korpusseitiger Lagerachse C und klappenseitiger Lagerachse D des Steuerarmes 7.Fig. 3c shows a continued from Fig. 3b movement of the flap 4, the two parts 7a, 7b of the control arm 7 were indeed through the intermediate lever 8 slightly stronger kinked, nevertheless, this results in comparison to FIG. 3b only an insignificant change in the distance S between the body-side bearing axis C and the flap-side bearing axis D of the control arm 7.
Fig. 3d zeigt eine von Fig. 3c weitergeführte Offenstellung der Klappe 4. Zu erkennen ist eine relativ starke Knickung der beiden Teile 7a, 7b des Steuerarmes 7, die durch den gekröpften Zwischenhebel 8 hervorgerufen wird. Zu erkennen ist der im Vergleich zu Fig. 3c deutlich reduzierte Abstand S zwischen korpusseitiger Lagerachse C und klappenseitiger Lagerachse D des Steuerarmes 7. Ausgehend von der in Fig. 3d gezeigten Stellung der Klappe 4 kann diese in die vollständige Offenstellung überführt werden, wobei durch die vorgeschlagene Kinematik des Stellmechanismus 5 die obere Kante 10 relativ nahe an den Schrankdeckel 3a des Möbelkorpus 3 herangeführt werden kann.3c shows an open position of the flap 4 which is continued from FIG. 3c. A relatively strong buckling of the two parts 7a, 7b of the control arm 7, which is caused by the cranked intermediate lever 8, can be seen. Can be seen in comparison to Fig. 3c significantly reduced distance S between the body-side bearing axis C and valve side bearing axis D of the control arm 7. Starting from the position shown in Fig. 3d the flap 4, this can be converted into the full open position, wherein by the proposed kinematics of the adjusting mechanism 5, the upper edge 10 can be brought relatively close to the cabinet lid 3a of the furniture body 3.
Fig. 4a - Fig. 4c zeigen ein alternatives Ausführungsbeispiel der Erfindung in einer Seitenansicht. Der Stellmechanismus 5 umfasst wie in den vorangegangenen Ausführungsbeispielen einen Stellarm 6, der korpusseitig an der Lagerachse A und klappenseitig an der Lagerachse B drehgelenkig angeordnet ist. Der Steuerarm 7 hingegen umfasst einen Teil 7a, der als Spindelmutter ausgebildet ist und der gleichzeitig die Lagerachse C des Steuerarmes 7 bildet. Im Weiteren umfasst der Steuerarm 7 eine Spindel 7b, die relativ zum Teil 7a (Spindelmutter) bewegbar ist. Im Weiteren umfasst der Steuerarm 7 einen Lagerteil 7c, der an der Lagerachse D am klappenseitigen Beschlagteil 9 drehgelenkig befestigt ist. Der Lagerteil 7c dient zur Aufnahme eines elektrischen Antriebes, durch den der Teil 7b (Spindel) rotierbar ist und dadurch längenveränderlich zum Teil 7a (Spindelmutter) bewegbar ist. Der am Lagerteil 7c angeordnete elektrische Antrieb kann hierbei wieder in Abhängigkeit der Winkellage des Stellarmes 6 betrieben werden, sodass ausgehend von der vollständigen Schließstellung der Klappe 4 nur eine geringfügige Längenänderung des Steuerarmes 7 erfolgt, während ab einem vorgegebenen oder vorgebbaren Öffnungswinkel des Stellarmes 6 bis hin zur vollständigen Offenstellung der Klappe 4 die effektive Hebelarmlänge des Steuerarmes 7 stärker als im ersten Schwenkbereich der Klappe 4 verändert wird.FIGS. 4a-4c show an alternative embodiment of the invention in a side view. The adjusting mechanism 5 comprises, as in the preceding embodiments, an actuating arm 6, which is pivotably arranged on the bearing axis A on the body side and on the bearing axis B on the valve side. The control arm 7, however, comprises a part 7a, which is designed as a spindle nut and at the same time forms the bearing axis C of the control arm 7. Furthermore, the control arm 7 comprises a spindle 7b, which is movable relative to the part 7a (spindle nut). Furthermore, the control arm 7 comprises a bearing part 7 c, which is pivotally attached to the bearing axis D on the flap-side fitting part 9. The bearing part 7c serves to receive an electric drive, by which the part 7b (spindle) is rotatable and thereby variable in length to part 7a (spindle nut) is movable. The arranged on the bearing part 7c electric drive can be operated again depending on the angular position of the actuating arm 6, so starting from the full closed position of the flap 4 only a slight change in length of the control arm 7, while from a predetermined or predetermined opening angle of the actuating arm 6 to for complete open position of the flap 4, the effective lever arm length of the control arm 7 is changed more than in the first pivoting range of the flap 4.
Fig. 4b zeigt einen im Vergleich zu Fig. 4a verkürzten Steuerarm 7 mit geringerer effektiver Hebelarmlänge, da der Teil 7b (Spindel) durch die herbeigeführte motorische Verstellung in das Innere des Möbelkorpus ragt. Selbstverständlich ist es auch möglich, den im Lagerteil 7c integrierten elektrischen Antrieb auch korpusseitig anzuordnen. Ebenso kann anstelle des gezeigten Spindelantriebes auch eine linear bewegbare Zahnstange mit einem drehbaren Ritzel zum Verstellen der Hebelarmlänge des Steuerarms 7 vorgesehen werden. Mit dem Bezugszeichen 13 ist schematisch eine Einrichtung zur Erfassung der Winkellage des Stellarmes 6 gekennzeichnet, durch die der elektrische Antrieb zur Verstellung der beiden Teile 7a, 7b zueinander selektiv ansteuerbar ist.Fig. 4b shows a shortened compared to Fig. 4a control arm 7 with lower effective Hebelarmlänge, since the part 7 b (spindle) by the induced motor Adjustment protrudes into the interior of the furniture body. Of course, it is also possible to arrange the electric drive integrated in the bearing part 7c also on the body side. Likewise, instead of the spindle drive shown, a linearly movable rack can be provided with a rotatable pinion for adjusting the lever arm length of the control arm 7. By the reference numeral 13, a device for detecting the angular position of the actuating arm 6 is schematically characterized, through which the electric drive for adjusting the two parts 7a, 7b is selectively controlled to each other.
Fig. 4c zeigt eine vergrößerte Darstellung des in Fig. 4b eingekreisten Bereiches mit korpusseitiger Spindelmutter 7a und Spindel 7b, die in das Innere des Möbelkorpus 3 ragt.4c shows an enlarged view of the area circled in FIG. 4b with body-side spindle nut 7a and spindle 7b projecting into the interior of the furniture body 3.
Fig. 5 zeigt ein mögliches Ausführungsbeispiel eines Spindelantriebes zur Realisierung des Steuerarmes 7. Ein am oder im Lagerteil 7c anordenbarer elektrischer Antrieb 14 mit Antriebswelle 14a wirkt direkt oder über einen Übersetzungsmechanismus auf den als Spindel ausgeführten Teil 7b. Durch eine vom elektrischen Antrieb 14 herbeigeführte Drehbewegung der Spindel kann die effektive Hebelarmlänge des Steuerarms 7 verändert, vorzugsweise verkürzt werden.FIG. 5 shows a possible embodiment of a spindle drive for the realization of the control arm 7. An electric drive 14 with drive shaft 14a, which can be arranged on or in the bearing part 7c, acts directly on the spindle-executed part 7b or via a transmission mechanism. By a brought about by the electric drive 14 rotational movement of the spindle, the effective lever arm length of the control arm 7 can be changed, preferably shortened.
Fig. 6 zeigt beispielhaft die Veränderung der effektiven Hebelarmlänge des Steuerarmes 7 als Funktion des Öffnungswinkel α des Stellarmes 6. An der Abszisse ist der Stellarmwinkel α, an der Ordinate die effektive Hebelarmlänge L des Steuerarmes (in %) angegeben. In einem ersten, von der vollständigen Schließstellung ausgehenden Öffnungswinkelbereich M1 des Stellarmes 6 behält der Steuerarm 7 im Wesentlichen seine effektive Hebelarmlänge L bei, wobei eine Parallelbewegung der Klappe ermöglicht wird. Ab etwa der Hälfte des Öffnungswinkels des Stellarmes α (beispielsweise ab etwa 60°) erfolgt in einem an den ersten Schwenkbereich M1 anschließenden zweiten Schwenkbereich M2 eine ausgeprägtere Verkürzung des Steuerarmes 7, wodurch die Klappe 4 stark über den Möbelkorpus 3 hinwegknickt. Die effektive Hebelarmlänge L des Steuerarmes 7 kann in der vollständigen Offenstellung des Stellarmes 6 etwa 50% der ursprünglichen effektiven Hebelarmlänge betragen. Angemerkt sei, dass hierbei für den Fachmann zahlreiche alternative Ausgestaltungen zur Realisierung des Kurvenverlaufs möglich sind. Die Erfindung beschränkt sich nicht auf die gezeigten Ausfϋhrungsbeispiele, sondern umfasst bzw. erstreckt sich auf alle Varianten und technische Äquivalente, welche in die Reichweite der nachfolgenden Ansprüche fallen können. Auch sind die in der Beschreibung gewählten Lageangaben, wie zum Beispiel oben, unten, seitlich, uns., auf die unmittelbar beschriebene sowie dargestellte Figur bezogen und sind bei einer Lageänderung sinngemäß auf die neue Lage zu übertragen. In den gezeigten Ausführungsbeispielen wurde aus Gründen der Einfachheit und des leichteren Verständnisses jeweils ein sich im Zuge des Bewegungsweges der Klappe 4 verkürzender Steuerarm 7 gezeigt, durch den die Klappe 4 im Zuge ihres Öffnungsverlaufes über den Möbelkorpus 3 hinweg schwenkbar ist. Selbstverständlich liegt es auch im Rahmen der Erfindung, dass sich die effektive Hebelarmlänge L des Steuerarmes 7 beim Öffnen der Klappe 4 verlängert, wodurch die Klappe 4 während ihres Öffnungsverlaufes auch über einen vor dem Möbelkorpus 3 befindlichen Benutzer hinweg schwenkbar ist. 6 shows by way of example the change in the effective lever arm length of the control arm 7 as a function of the opening angle α of the actuating arm 6. The abscissa represents the actuating arm angle α, the ordinate represents the effective lever arm length L of the control arm (in%). In a first, starting from the full closed position opening angle range M1 of the actuating arm 6, the control arm 7 substantially maintains its effective lever arm length L, wherein a parallel movement of the flap is made possible. From about half of the opening angle of the actuating arm α (for example, from about 60 °) takes place in a subsequent to the first pivoting area M1 second pivot area M2 a more pronounced shortening of the control arm 7, whereby the flap 4 kinks over the furniture body 3 strong. The effective Hebelarmlänge L of the control arm 7 may be about 50% of the original effective Hebelarmlänge in the full open position of the actuating arm 6. It should be noted that numerous alternative embodiments for realizing the curve are possible for the person skilled in the art. The invention is not limited to the embodiments shown, but includes or extends to all variants and technical equivalents, which may fall within the scope of the following claims. Also, the position information selected in the description, such as top, bottom, side, us, referred to the immediately described and illustrated figure and are mutatis mutandis transferred to the new situation in a change in position. In the exemplary embodiments shown, a control arm 7 shortening in the course of the movement path of the flap 4 was shown, for reasons of simplicity and ease of understanding, by means of which the flap 4 can be pivoted over the furniture carcass 3 in the course of its opening course. Of course, it is also within the scope of the invention that extends the effective Hebelarmlänge L of the control arm 7 when opening the flap 4, whereby the flap 4 is pivoted away during its opening course also over a user located in front of the furniture body 3 user.
