Coupling device has at least one movably mounted first coupling element with a toothing, wherein the at least one first coupling element can be brought into engagement with a second coupling element when a predetermined pivoting speed of the actuating arm is exceeded, whereby the pivoting movement of the at least one actuating arm is braked or prevented, the second Coupling element has at least one engagement section through which the two coupling elements can be brought into engagement with one another.
Im Weiteren betrifft die Erfindung ein Möbel mit einem Möbelkorpus, einer relativ zum Möbelkorpus bewegbar gelagerten Möbelklappe und mit einem Stellantrieb der zu beschreibenden Art zum Bewegen des Möbelklappe. Furthermore, the invention relates to a piece of furniture with a furniture body, a furniture flap mounted movably relative to the furniture body and with an actuator of the type to be described for moving the furniture flap.
Stellantriebe zum Bewegen von Möbelklappen weisen üblicherweise zumindest einen schwenkbar gelagerten Stellarm und einen Kraftspeicher in Form einer Federvorrichtung zur Kraftbeaufschlagung des Stellarmes auf. Durch den Kraftspeicher ist das Gewicht der Möbelklappe zumindest teilweise kompensierbar, sodass die Bewegung der Möbelklappe für eine Person erleichtert wird. Der Stellarm ist je nach Größe und Gewicht der Möbelklappe mit extrem hohen Vorspannkräften des Kraftspeichers in Richtung Offenstellung beaufschlagt. Kritische Situationen können sich insbesondere dann ergeben, wenn die Möbelklappe noch nicht mit dem Stellarm verbunden ist. In einem solchen Fall wirkt auf den Stellarm auch kein Gegengewicht, wodurch der Stellarm durch die Kraft des Kraftspeichers massiv ausschlagen und Verletzungen an Personen und Beschädigungen an Objekten verursachen kann. Actuators for moving furniture flaps usually have at least one pivotably mounted actuating arm and an energy store in the form of a spring device for applying force to the actuating arm. The weight of the furniture flap can be at least partially compensated for by the energy store, so that the movement of the furniture flap is made easier for one person. Depending on the size and weight of the furniture flap, the actuating arm is subjected to extremely high pretensioning forces of the energy accumulator in the direction of the open position. Critical situations can arise in particular if the furniture flap is not yet with the adjusting arm connected is. In such a case, no counterweight acts on the actuating arm, which means that the actuating arm can deflect massively due to the force of the energy accumulator and can cause injuries to persons and damage to objects.
In der WO 2006/069412 A1 und in der WO 2010/051569 A1 sind Stellantriebe zum Bewegen von Möbelklappen offenbart, welche mit einer Fliehkraftkupplung zur Verhinderung eines unkontrollierten Ausschlages des Stellarmes in Richtung Offenstellung ausgestattet sind. Die Fliehkraftkupplung stellt sicher, dass der Stellarm unterhalb einer vorgegebenen Schwenkgeschwindigkeit in einer kontrollierten Weise bewegbar ist. Oberhalb der vorgegebenen Schwenkgeschwindigkeit des Stellarmes wird eine selbsttätige Verriegelung des Stellarmes durch die Fliehkraftkupplung herbeigeführt, wodurch der Stellarm in seiner Schwenklage verriegelt wird und nicht weiter in Richtung Offenstellung ausschlagen kann. WO 2006/069412 A1 and WO 2010/051569 A1 disclose actuators for moving furniture flaps which are equipped with a centrifugal clutch to prevent an uncontrolled deflection of the actuating arm in the direction of the open position. The centrifugal clutch ensures that the actuating arm can be moved in a controlled manner below a predetermined swiveling speed. Above the predetermined swiveling speed of the actuating arm, an automatic locking of the actuating arm is brought about by the centrifugal clutch, whereby the actuating arm is locked in its pivoting position and cannot deflect further in the direction of the open position.
In der Praxis können sich insofern Probleme mit der Fliehkraftkupplung ergeben, wenn der Stellantrieb bereits am Möbel vormontiert ist und der Stellarm einerseits am Möbelkorpus und andererseits an der Möbelklappe angelenkt ist. Wenn sich die Möbelklappe in einer geschlossenen Stellung relativ zum Möbelkorpus befindet, so kann es Vorkommen, dass sich die Kupplungselemente der Fliehkraftkupplung in einer unerwünschten Weise miteinander verkeilen, beispielsweise durch einen Transport oder durch eine Kippbewegung des Möbelkorpus bei seiner Montage. Der Stellarm ist durch die blockierte Fliehkraftkupplung in seiner geschlossenen Lage arretiert und kann durch die am Möbelkorpus anliegende Möbelklappe auch nicht mehr weiter in Richtung Schließstellung gedrückt werden, wodurch sich die Verkeilung der Fliehkraftkupplung und die Blockierung des Stellarmes lösen lassen könnte. Ein Öffnen der Möbelklappe ist dann oft nur mehr mit einhergehenden Beschädigungen der Möbelklappe oder des Stellantriebes möglich. In practice, problems can arise with the centrifugal clutch if the actuator is already preassembled on the furniture and the actuating arm is articulated on the one hand on the furniture body and on the other hand on the furniture flap. If the furniture flap is in a closed position relative to the furniture body, it may happen that the coupling elements of the centrifugal clutch wedge together in an undesirable manner, for example by transport or by a tilting movement of the furniture body during its assembly. The actuating arm is locked in its closed position by the blocked centrifugal clutch and cannot be pushed any further towards the closed position by the furniture flap on the furniture body, as a result of which the wedging of the centrifugal clutch and the blocking of the actuating arm could be released. Opening the furniture flap is then often only possible with accompanying damage to the furniture flap or the actuator.
Aufgabe der vorliegenden Erfindung ist es, einen Stellantrieb der eingangs erwähnten Gattung unter Vermeidung der oben diskutierten Nachteile anzugeben. The object of the present invention is to provide an actuator of the type mentioned at the outset, avoiding the disadvantages discussed above.
Dies wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausführungsbeispiele der Erfindung sind in den abhängigen Ansprüchen definiert. Gemäß der Erfindung ist vorgesehen, dass das zweite Kupplungselement wenigstens einen vom Eingriffsabschnitt gesonderten Freilaufabschnitt aufweist, wobei das erste Kupplungselement in der Schließstellung des Stellarmes innerhalb des Freilaufabschnitts des zweiten Kupplungselementes angeordnet ist, wodurch die beiden Kupplungselemente in der Schließstellung des Stellarmes voneinander entkoppelt sind. This is achieved according to the invention by the features of patent claim 1. Further advantageous embodiments of the invention are defined in the dependent claims. According to the invention it is provided that the second coupling element has at least one freewheel section separate from the engagement section, the first coupling element being arranged in the closed position of the actuating arm within the freewheel section of the second coupling element, whereby the two coupling elements are decoupled from one another in the closed position of the actuating arm.
Mit anderen Worten weist das zweite Kupplungselement zumindest einen Freilaufabschnitt auf, welcher einen Eingriff, insbesondere eine formschlüssige Verriegelung, der beiden Kupplungselemente zueinander in der Schließstellung des Stellarmes und/oder in einem der Schließstellung des Stellarmes unmittelbar vorgelagerten Schwenkbereich verhindert. In other words, the second coupling element has at least one freewheel section, which prevents an engagement, in particular a form-locking locking, of the two coupling elements with respect to one another in the closed position of the actuating arm and / or in a pivoting range immediately preceding the closed position of the actuating arm.
In der Schließstellung des Stellarmes ist das erste Kupplungselement am Freilaufabschnitt des zweiten Kupplungselementes anlegbar, wobei die Oberfläche des Freilaufabschnittes im Wesentlichen zahnlos oder im Wesentlichen glatt ausgeführt werden kann. Der Freilaufabschnitt kann auch eine andere Oberflächenbeschaffenheit aufweisen, jedenfalls sollte aber sichergestellt sein, dass in der Schließstellung des Stellarmes eine Verriegelung zwischen den beiden Kupplungselementen nicht möglich ist. In the closed position of the actuating arm, the first coupling element can be placed on the freewheel section of the second coupling element, it being possible for the surface of the freewheeling section to be essentially toothless or essentially smooth. The freewheel section can also have a different surface quality, but in any case it should be ensured that a locking between the two coupling elements is not possible in the closed position of the adjusting arm.
Gemäß einem Ausführungsbeispiel kann vorgesehen sein, dass die beiden Kupplungselemente durch den Freilaufabschnitt des zweiten Kupplungselementes innerhalb eines Schwenkwinkelbereiches des Stellarmes, welcher sich zwischen der Schließstellung des Stellarmes und einer Offenstellung des Stellarmes von maximal 30°, vorzugsweise maximal 20°, ergibt, voneinander entkoppelt sind. According to one exemplary embodiment, it can be provided that the two coupling elements are decoupled from one another by the freewheeling section of the second coupling element within a swivel angle range of the actuating arm, which results between the closed position of the actuating arm and an open position of the actuating arm of at most 30 °, preferably at most 20 ° .
Gemäß einem Ausführungsbeispiel der Erfindung kann vorgesehen sein, das zweite Kupplungselement eine im Wesentlichen ringförmige Innenkontur aufweist, wobei sowohl der Eingriffsabschnitt als auch der Freilaufabschnitt an der ringförmigen Innenkontur des zweiten Kupplungselementes angeordnet oder ausgebildet sind. According to one exemplary embodiment of the invention, it can be provided that the second coupling element has a substantially annular inner contour, both the engagement section and the freewheel section being arranged or formed on the ring-shaped inner contour of the second coupling element.
Der Eingriffsabschnitt des zweiten Kupplungselementes kann beispielsweise eine Gegenverzahnung zur formschlüssigen Verriegelung mit dem ersten Kupplungselement aufweisen. Der Freilaufabschnitt kann hingegen eine im Wesentlichen glatte Anlagefläche ausbilden, an welcher das erste Kupplungselement in der Schließstellung des Stellarmes anlegbar ist. The engagement section of the second coupling element can, for example, counter teeth for positive locking with the first coupling element exhibit. The freewheel section, however, can form an essentially smooth contact surface, against which the first coupling element can be placed in the closed position of the actuating arm.

Fig. 1 zeigt ein Möbel 1 mit einem Möbelkorpus 2 in einer Seitenansicht, wobei eine Möbelklappe 3 durch einen Stellantrieb 4 relativ zum Möbelkorpus 2 bewegbar gelagert ist. Im gezeigten Ausführungsbeispiel ist die Möbelklappe 3 zweiteilig ausgebildet und umfasst eine erste Teilklappe 3a, welche durch Scharniere 10 an einer Unterseite einer Deckplatte 2a des Möbelkorpus 2 schwenkbar befestigt ist. Die zweite Teilklappe 3b ist mit der ersten Teilklappe 3a gelenkig verbunden. Der Stellantrieb 4 weist ein am Möbelkorpus 2 zu befestigendes Gehäuse 5 und zumindest einen am Gehäuse 5 schwenkbar gelagerten, vorzugsweise längenverstellbar ausgebildeten, Stellarm 7 zum Bewegen der Möbelklappe 3 auf. Der Stellarm 7 ist über eine Gelenkachse 8 schwenkbar mit einem Beschlagteil 9 verbunden, wobei das Beschlagteil 9 - vorzugsweise über eine Montageplatte - an einer Innenseite der zweiten Teilklappe 3b zu befestigen ist. Fig. 1 shows a piece of furniture 1 with a furniture body 2 in a side view, wherein a furniture flap 3 is movably mounted relative to the furniture body 2 by an actuator 4. In the exemplary embodiment shown, the furniture flap 3 is formed in two parts and comprises a first partial flap 3a, which is pivotally attached to a lower side of a cover plate 2a of the furniture body 2 by hinges 10. The second partial flap 3b is articulated to the first partial flap 3a. The actuator 4 has a housing 5 to be fastened to the furniture body 2 and at least one adjusting arm 7, which is pivotably mounted on the housing 5 and is preferably adjustable in length, for moving the furniture flap 3. The actuating arm 7 is via an articulated axis 8 pivotally connected to a fitting part 9, the fitting part 9 being fastened to an inside of the second partial flap 3b, preferably via a mounting plate.
Fig. 2 zeigt eine Seitenansicht des Möbels 1 gemäß Fig. 1 mit einer in Bezug zum Möbelkorpus 2 geschlossenen Möbelklappe 3. Der Stellantrieb 4 weist einen Kraftspeicher 11 (Fig. 3a) zur Kraftbeaufschlagung des Stellarmes 7 auf, wodurch das Gewicht der Möbelklappe 3 zumindest teilweise kompensierbar ist. Überdies weist der Stellantrieb 4 eine (hier nicht ersichtliche) Kupplungsvorrichtung 19 zum Bremsen oder Verhindern einer Schwenkbewegung des zumindest einen Stellarmes 7 auf, sodass ein unbeabsichtigtes Öffnen oder Ausschlagen des leeren Stellarmes 7, an dem also noch keine Möbelklappe 3 befestigt ist, durch eine in Öffnungsrichtung wirkende Kraft des Kraftspeichers 11 vermieden werden kann. Ist die Möbelklappe 3 am Stellarm 7 befestigt, so ist die Kupplungsvorrichtung 19 nicht aktiv, weil die Schwenkgeschwindigkeit des Stellarmes 7 bei einer am Stellarm 7 montierten Möbelklappe 3 stets weit unterhalb eines vorgegebenen kritischen Wertes liegt. Die Kupplungsvorrichtung 19 des Stellantriebes 4 kann sich allerdings in der gezeigten Schließstellung der Möbelklappe 3 verklemmen, sodass sich die Möbelklappe 3 weder in Öffnungsrichtung noch in Schließrichtung bewegen lässt und die Verklemmung der Kupplungsvorrichtung 19 nicht gelöst werden kann. FIG. 2 shows a side view of the furniture 1 according to FIG. 1 with a furniture flap 3 closed in relation to the furniture body 2. The actuator 4 has an energy accumulator 11 (FIG. 3a) for applying force to the actuating arm 7, whereby the weight of the furniture flap 3 at least is partially compensable. In addition, the actuator 4 has a coupling device 19 (not shown here) for braking or preventing a pivoting movement of the at least one actuating arm 7, so that an inadvertent opening or knocking out of the empty actuating arm 7, to which no furniture flap 3 is yet attached, by a Force of the force accumulator 11 acting in the opening direction can be avoided. If the furniture flap 3 is attached to the actuating arm 7, the coupling device 19 is not active because the pivoting speed of the actuating arm 7 is always far below a predetermined critical value when the furniture flap 3 is mounted on the actuating arm 7. However, the coupling device 19 of the actuator 4 can jam in the shown closed position of the furniture flap 3, so that the furniture flap 3 cannot be moved in the opening direction or in the closing direction and the jamming of the coupling device 19 cannot be released.
Fig. 3a zeigt den Stellantrieb 4 mit dem am Möbelkorpus 2 zu befestigenden Gehäuse 5 in einer Seitenansicht. Der (hier nicht gezeigte) Stellarm 7 ist mit einem um die Drehachse 6 drehbaren Koppelstück 17 lösbar verbindbar, wobei das Koppelstück 17 zur formschlüssigen Befestigung des Stellarmes 7 mehrere Ausnehmungen 18 aufweist. Zur Kraftbeaufschlagung des Stellarmes 7 ist ein Kraftspeicher 11 vorgesehen, welcher zumindest eine Schraubenfeder, beispielsweise zumindest eine Druckfeder oder zumindest eine Schraubenfeder) aufweist. Gemäß einer bevorzugten Ausführungsform weist der Kraftspeicher 11 ein Federpaket mit mehreren parallel angeordneten Druckfedern auf. Der Kraftspeicher 11 ist über eine Angriffsstelle 16 mit einem um eine Drehachse 13 schwenkbaren Zwischenhebel 12 beweglich verbunden, wobei am Zwischenhebel 12 eine Druckrolle 14 drehbar gelagert ist. Am Koppelstück 17 ist eine Steuerkontur 15 ausgebildet, wobei die Druckrolle 14 des Zwischenhebels 12 bei einer Bewegung des Stellarmes 7 um die Drehachse 6 entlang der Steuerkontur 15 des Koppelstückes 17 verfahrbar ist. 3a shows the side view of the actuator 4 with the housing 5 to be attached to the furniture body 2. The actuating arm 7 (not shown here) can be detachably connected to a coupling piece 17 rotatable about the axis of rotation 6, the coupling piece 17 having a plurality of recesses 18 for the form-fitting attachment of the actuating arm 7. To apply force to the actuating arm 7, a force accumulator 11 is provided which has at least one helical spring, for example at least one compression spring or at least one helical spring). According to a preferred embodiment, the energy accumulator 11 has a spring assembly with a plurality of compression springs arranged in parallel. The energy store 11 is movably connected via an engagement point 16 to an intermediate lever 12 pivotable about an axis of rotation 13, a pressure roller 14 being rotatably mounted on the intermediate lever 12. A control contour 15 is formed on the coupling piece 17, the pressure roller 14 of the intermediate lever 12 can be moved along the control contour 15 of the coupling piece 17 when the actuating arm 7 moves about the axis of rotation 6.
Der Stellantrieb 4 weist eine Kupplungsvorrichtung 19 zum Bremsen oder Verhindern einer Schwenkbewegung des zumindest einen Stellarmes 7 auf, wodurch ein unbeabsichtigtes Ausschlagen des Stellarmes 7 aufgrund einer auf den Stellarm 7 ausgeübten Kraft des Kraftspeichers 11 in Richtung der Offenstellung verhindert ist. Die Kupplungsvorrichtung 19 kann beispielsweise eine Fliehkraftkupplung aufweisen. Die Kupplungsvorrichtung 19 ist durch ein um die Rotationsachse 22 drehbares Zahnrad 20 antreibbar, wobei das Zahnrad 20 bei einer Bewegung des Stellarmes 7 um die Drehachse 6 entlang einer, vorzugsweise bogenförmig ausgebildeten, Zahnschiene 21 verfahrbar ist. Die Zahnschiene 21 ist am Gehäuse 5 des Stellantriebes 4 angeordnet oder ausgebildet. Das Zahnrad 20 und die Zahnschiene 21 bilden ein Übersetzungsgetriebe, durch welches eine Schwenkgeschwindigkeit des Stellarmes 7 über einen Bereich des Schwenkweges des Stellarmes 7 auf eine höhere Drehgeschwindigkeit einer auf der Rotationsachse 22 gelagerten Welle 30 (Fig. 6a) übersetzbar ist. Bei einem Übersetzungsverhältnis des Übersetzungsgetriebes von 1 :4 bedeutet dies, dass eine Winkeländerung des Stellarmes 7 um 15° zu einer vierfachen Winkeländerung der auf der Rotationsachse 22 gelagerten Welle 30 führt. Die Welle 30 wird dabei also um 60° verdreht. Auf diese Weise kann die Reaktionszeit der als Fliehkraftkupplung ausgebildeten Kupplungsvorrichtung 19 erheblich verkürzt werden. The actuator 4 has a coupling device 19 for braking or preventing a pivoting movement of the at least one actuating arm 7, thereby preventing the actuating arm 7 from unintentionally deflecting due to a force exerted on the actuating arm 7 by the energy accumulator 11 in the direction of the open position. The clutch device 19 can have, for example, a centrifugal clutch. The coupling device 19 can be driven by a gearwheel 20 which can be rotated about the axis of rotation 22, the gearwheel 20 being movable along a, preferably arched, toothed rail 21 when the actuating arm 7 is moved about the axis of rotation 6. The toothed rail 21 is arranged or formed on the housing 5 of the actuator 4. The gear wheel 20 and the toothed rail 21 form a transmission gear, by means of which a swiveling speed of the actuating arm 7 can be translated over a region of the swiveling path of the actuating arm 7 to a higher rotational speed of a shaft 30 mounted on the axis of rotation 22 (FIG. 6a). With a transmission ratio of the transmission gear of 1: 4, this means that a change in the angle of the actuating arm 7 by 15 ° leads to a fourfold change in the angle of the shaft 30 mounted on the axis of rotation 22. The shaft 30 is thus rotated by 60 °. In this way, the reaction time of the clutch device 19 designed as a centrifugal clutch can be shortened considerably.
Fig. 3b zeigt den in Fig. 3a eingerahmten Bereich in einer vergrößerten Ansicht. Bei einer Bewegung des Stellarmes 7 (d.h. des Kupplungsstückes 17) läuft das Zahnrad 20 entlang der Zahnschiene 21 ab. Die Kupplungsvorrichtung 19 weist zumindest ein bewegbar gelagertes erstes Kupplungselement 23a, 23b (Fig. 3c) auf, welches bei einer Überschreitung einer vorgegebenen Schwenkgeschwindigkeit des Stellarmes 7 mit einem zweiten Kupplungselement 24 in Eingriff bringbar ist, wodurch die Schwenkbewegung des Stellarmes 7 gebremst oder verhindert wird. 3b shows the area framed in FIG. 3a in an enlarged view. When the actuating arm 7 (i.e. the coupling piece 17) moves, the toothed wheel 20 runs along the toothed rail 21. The coupling device 19 has at least one movably mounted first coupling element 23a, 23b (FIG. 3c), which can be brought into engagement with a second coupling element 24 when a predetermined pivoting speed of the actuating arm 7 is exceeded, as a result of which the pivoting movement of the actuating arm 7 is braked or prevented .
Fig. 3c zeigt eine vergrößerte Detaildarstellung der Kupplungsvorrichtung 19, wobei zwei erste Kupplungselemente 23a, 23b auf einer gemeinsamen, um die3c shows an enlarged detailed view of the coupling device 19, with two first coupling elements 23a, 23b on a common one, around the
Rotationsachse 22 drehbaren Welle 30 angeordnet sind. Die beiden ersten Kupplungselemente 23a, 23b sind in einer axialen Richtung der Welle 30 voneinander beabstandet und sind durch das an der Zahnschiene 21 ablaufende Zahnrad 20 um die Rotationsachse 22 antreibbar. Die Kupplungselemente 23a, 23b weisen jeweils eine Verzahnung 34a, 34b auf, welche bei Überschreitung einer vorgegebenenRotation axis 22 rotatable shaft 30 are arranged. The two first coupling elements 23a, 23b are apart from one another in an axial direction of the shaft 30 spaced and can be driven by the gear 20 running on the toothed rail 21 about the axis of rotation 22. The coupling elements 23a, 23b each have a toothing 34a, 34b, which when a predetermined one is exceeded
Schwenkgeschwindigkeit des Stellarmes 7 mit einer Gegenverzahnung 35 eines am zweiten Kupplungselement 24 angeordneten Eingriffsabschnitts 25 formschlüssig verriegelbar sind. Zu erkennen ist, dass am zweiten Kupplungselement 24 zumindest ein Freilaufabschnitt 26 angeordnet ist, welcher eine Verriegelung des ersten Kupplungselementes 23a mit dem zweiten Kupplungselement 24 in der gezeigten Schließstellung des Stellarmes 7 verhindert. Für den beispielhaften Fall, dass sich der Winkelbereich des Freilaufabschnittes 26 über einen Winkelbereich von 28° erstreckt, so ist eine Verriegelung des Stellarmes 7 bei dem bereits erwähnten Übersetzungsverhältnis des Übersetzungsgetriebes von 1 :4 innerhalb eines Winkelbereiches von 7° nicht möglich. Der Freilaufabschnitt 26 kann eine bogenförmige ausgebildete, glatte Kontur aufweisen, welche frei von Vertiefungen oder Erhebungen ausgebildet ist. The pivoting speed of the actuating arm 7 can be positively locked with counter teeth 35 of an engagement section 25 arranged on the second coupling element 24. It can be seen that at least one freewheel section 26 is arranged on the second coupling element 24, which prevents the first coupling element 23a from locking with the second coupling element 24 in the closed position of the actuating arm 7 shown. In the exemplary case that the angular range of the freewheeling section 26 extends over an angular range of 28 °, the actuating arm 7 cannot be locked at the already mentioned transmission ratio of 1: 4 within an angular range of 7 °. The freewheel section 26 can have an arcuate, smooth contour, which is free of depressions or elevations.
Die ersten Kupplungselemente 23a, 23b sind durch Federelemente 27a, 27b in Richtung einer von dem zweiten Kupplungselement 24 entkoppelten Stellung vorgespannt. Die Federelemente 27a, 27b dienen dazu, die Kupplungselemente 23a, 23b in eine kompakte Ruhelage zu drücken und eine definierte Auslösekraft bereitzustellen. Erst nach Überwindung der definierten Auslösekraft sind die beiden ersten Kupplungselemente 23a, 23b mit dem zweiten Kupplungselement 24 lösbar verriegelbar. The first coupling elements 23a, 23b are biased by spring elements 27a, 27b in the direction of a position decoupled from the second coupling element 24. The spring elements 27a, 27b serve to press the coupling elements 23a, 23b into a compact rest position and to provide a defined triggering force. Only after the defined triggering force has been overcome can the two first coupling elements 23a, 23b be releasably locked to the second coupling element 24.
Fig. 4a zeigt eine Seitenansicht des Stellantriebes 4, wobei der Stellarm 7 (d.h. das Koppelstück 17) in einer Offenstellung von etwa 20° durch die Kupplungsvorrichtung 19 verriegelt ist. Fig. 4b zeigt den in Fig. 4a eingerahmten Bereich in einer vergrößerten Ansicht, wobei der Stellarm 7 durch eine Überschreitung der vorgegebenen Schwenkgeschwindigkeit durch eine Verriegelung der beiden ersten Kupplungselemente 23a, 23b mit dem zweiten Kupplungselement 24 formschlüssig verriegelt ist. Ausgehend von der in Fig. 4b gezeigten Stellung kann die Verriegelung des Stellarmes 7 gelöst werden, indem der Stellarm 7 manuell in Richtung der Schließstellung gedrückt wird. Die beiden ersten Kupplungselemente 23a, 23b sind dann durch die Kraft der Federelemente 27a, 27b vom zweiten Kupplungselement 24 entriegelbar. 4a shows a side view of the actuator 4, the actuating arm 7 (ie the coupling piece 17) being locked in an open position of approximately 20 ° by the coupling device 19. 4b shows the area framed in FIG. 4a in an enlarged view, the actuating arm 7 being positively locked to the second coupling element 24 by exceeding the predetermined swiveling speed by locking the two first coupling elements 23a, 23b. Starting from the position shown in FIG. 4b, the locking of the actuating arm 7 can be released by manually pushing the actuating arm 7 in the direction of the closed position. The two first coupling elements 23a, 23b are then unlockable by the force of the spring elements 27a, 27b from the second coupling element 24.
Fig. 4c zeigt eine vergrößerte Darstellung der Kupplungsvorrichtung 19, wobei die Verzahnungen 34a, 34b der ersten Kupplungselemente 23a, 23b in dieFIG. 4c shows an enlarged illustration of the coupling device 19, the toothings 34a, 34b of the first coupling elements 23a, 23b in the
Gegenverzahnung 35 des Eingriffsabschnittes 25 des zweiten Kupplungselementes 24 eingreifen. Der Eingriffsabschnitt 25 kann sich beispielsweise über einen Winkelbereich von 330° erstrecken, während sich der Freilaufabschnitt 26 über 30° erstreckt. Counter teeth 35 of the engaging portion 25 of the second coupling element 24 engage. The engagement section 25 can extend, for example, over an angular range of 330 °, while the freewheel section 26 extends over 30 °.
Fig. 5a zeigt eine perspektivische Ansicht des mit dem Stellarm 7 zu verbindenden Koppelstückes 17 des Stellantriebes 4. Das Koppelstück 17 weist mehrere Ausnehmungen 18 auf, in welchen in einem montierten Zustand des Stellarmes 7 allfällige Befestigungselemente des Stellarmes 7, insbesondere Stifte und/oder ein federbelasteter Kipphebel des Stellarmes 7, aufgenommen sind. Die Steuerkontur 15 zur verfahrbaren Lagerung der Druckrolle 14 wird durch einen Umfangsrand zweier Scheibenteile 28a, 28b gebildet, welche parallel voneinander beabstandet sind. Der Stellarm 7 ist zusammen mit dem Koppelstück 17 um die Drehachse 6 schwenkbar gelagert, wobei das um die Rotationsachse 22 drehbare Zahnrad 20 entlang der gebogenen Zahnschiene 21 des Stellantriebes 4 verfahrbar ist. Der Stellarm 7, an welchem keine Möbelklappe 3 montiert ist, ist bei Überschreitung einer vorgegebenen Schwenkgeschwindigkeit durch die Kupplungsvorrichtung 19 formschlüssig verriegelbar. Die Drehachse 6 des Stellarmes 7 und die Rotationsachse 22 des Zahnrades 20 sind im Wesentlichen parallel voneinander beabstandet. Fig. 5b zeigt den in Fig. 5a eingekreisten Bereich in einer vergrößerten Ansicht. 5a shows a perspective view of the coupling piece 17 of the actuator 4 to be connected to the actuating arm 7. The coupling piece 17 has a plurality of recesses 18, in which, in the assembled state of the actuating arm 7, any fastening elements of the actuating arm 7, in particular pins and / or a spring-loaded rocker arm of the actuating arm 7, are added. The control contour 15 for the movable mounting of the pressure roller 14 is formed by a peripheral edge of two disk parts 28a, 28b, which are spaced apart in parallel. The actuating arm 7 is mounted together with the coupling piece 17 so as to be pivotable about the axis of rotation 6, the gear wheel 20 which can be rotated about the axis of rotation 22 being movable along the curved toothed rail 21 of the actuator 4. The actuating arm 7, on which no furniture flap 3 is mounted, can be positively locked by the coupling device 19 when a predetermined swiveling speed is exceeded. The axis of rotation 6 of the actuating arm 7 and the axis of rotation 22 of the gearwheel 20 are spaced apart essentially in parallel. FIG. 5b shows the area encircled in FIG. 5a in an enlarged view.
