Definitions
- the present invention relates to a Stellarmanrete for at least one pivotally mounted actuating arm with the features of the preamble of claim 1, a piece of furniture with such a Stellarmanrete and a method for producing such Stellarmantriebs.
- An actuator with the features of the preamble of claim 1 is for example DE-U-202010015092 known.
- the object of the invention is to provide a Stellarmantriebs, in which the aforementioned disadvantages do not occur.
- the object is achieved in that at least a first and a second lever of Stellarmantriebs are arranged parallel to each other with a lateral distance and the levers each have two axial bores with a first pitch, protrudes through each of which a pivot pin, wherein a third lever is provided , which has receptacles for the axle bolts with a second standard distance, wherein the second standard distance is greater or less than that first standard distance and wherein the axle bolts each protrude through the axial bores of the first and the second lever and are at least partially received in the receptacles of the third lever. It can thereby be achieved that the composite created by means of axle bolts is stabilized from the first and the second lever by the addition of a third lever.
- a first standard distance may be understood to mean the desired spacing of the bores for receiving the axle bolts in the first and in the second lever, wherein the actual distance of the axle bores resulting in the production of the levers may deviate from the standard distance.
- a substantially pin-shaped or cylindrical component for example a steel pin, can be understood as having a component diameter corresponding essentially to the diameter of the axle bores.
- the actual diameter of the axle pin and the axle bores may differ slightly in production from the desired diameters. Due to the fact that the axle bolts projecting respectively through the axle bores of the first and the second lever also at least partially in the receptacles of the third lever, which have a different second from the first standard distance, any deviations occurring in the production can be compensated.
- the axle bolts can be braced in such a way in the receptacles and axle bores that it can come to a play-free composite of the first and the second lever by means of the third lever.
- first and the second lever are formed substantially flat.
- a flat design of the lever is procedurally simple, for example by punching, produced and also facilitates the attachment of the axial bores, which can also be produced in a stamping process.
- a planar design of the lever with substantially transversely (normal) to the surfaces extending axle bolt for connecting the lever can also be characterized by advantageous large bending strength.
- first and the second lever are identical. This makes it possible to make no distinction between the components corresponding to the first and the second lever and the tools necessary for their production and machining during the production of the actuating arm drive and in particular the lever.
- the third lever may be substantially flat. On the one hand, this enables a compact combination of the first, second and third levers. On the other hand, a planar design of the third lever, in particular with a resilient deformation of the third lever for at least partially receiving the axle bolts prove to be advantageous.
- the third lever is elastically resilient.
- the third lever for at least partially receiving the respectively projecting through the axle bores of the first and the second lever axle bolts are deformed.
- the third lever has a substantially curved, preferably wavy, shape. As a result, a resilient deformability of the lever can be facilitated.
- the third lever has a spring constant in a range of 50 to 250 N / mm, preferably in a range of 100 to 150 N / mm (Newton per millimeter).
- a spring force of 50 to 250 Newton preferably a spring force of 100 to 150 Newton
- a spring constant in such a range represents a good compromise between simple assembly and clearance compensation on the one hand and easier mobility in the operation of Stellarmantriebs other hand.
- the receptacles of the axle bolts may also be advantageous for the receptacles of the axle bolts to be formed in the third lever in the form of an axle bore and / or as an indentation.
- the receptacles of the axle bolts may also be advantageous for the receptacles of the axle bolts to be formed in the third lever in the form of an axle bore and / or as an indentation.
- Such a recess may be particularly advantageous if the third lever is to take place after the connection of the first lever to the second lever by means of the axle bolt.
- the third lever for example, provided with an axial bore and a recess third lever with the Achsbohrung pivotally mounted on one of the axle and be swung or clipped with the indentation on the second axle.
- the third lever-preferably substantially completely-to be arranged between the first and the second lever. By arranging the third lever between the other levers this can be at least partially covered. In particular, in the case of a spring-elastic tensioning of the third lever between the axle bolts, a substantially symmetrical application of force to the first and the second lever may occur.
- the lateral distance of the first lever to the second lever corresponds substantially to the thickness of the third lever.
- the deviation of the second standard distance from the first standard distance is in a range of 1 to 10%, preferably in a range of 5 to 10%. This can be achieved on the one hand, that there is a sufficiently large tolerance compensation of the mounted in the axle bores axle and on the other hand also avoided that occur in a pivotal mounting of the axle in the Achsbohronne negative impact on the operation of Stellarmantriebs frictional forces.
- the deviation of the second standard spacing from the first standard spacing may be in a range of 0.1 to 5 mm, preferably in a range of 0.1 to 1 mm.
- a deviation in this range can ensure that the desired second standard distance within the range Can manufacture manufacturing tolerances and on the other hand can be ensured by a deviation in this area an effective tolerance compensation.
- the second standard spacing may be greater than the first standard spacing.
- the distance of the receptacles of the third lever for receiving the projecting through the axle holes of the first and second pivot axle can be reduced by upsetting substantially to the first standard distance - for example, by elastic deformation of the third lever - and so it to a spread apart of the two Axle bolts come.
- the deviation of the second standard distance to the first standard distance is selected such that the load of the axle of the lever is gleichgeartet by the third lever, as the load on the axle by the weight of a mounted on Stellarmantrieb flap in a mounting position of Stellarmantriebs.
- the ratio of the height of the third lever to the second standard distance of the third lever is 0.35 or less, preferably 0.25 or less, particularly preferably 0.15 or less.
- the third lever at least in sections, such a ratio between the height and the distance of the recordings.
- the height of the third lever can be understood as an extension, extending at least in sections, substantially transversely to the connecting line of the receptacles of the axle bolts (second standard spacing) of the third lever.
- Protection is also desired for a piece of furniture with at least one actuating arm drive as described above.
- the third lever is biased during assembly of the Stellarmantriebs by stretching or upsetting to the first standard distance, while maintaining this bias in the installed state.
- the third lever may, for example, have a receptacle in the form of an axle bore and a further receptacle in the form of a recess.
- the third lever can be used in one process step be arranged between the first and the second lever, the levers are provided in a further method step with a pivot pin through the respective axial bores, the first and the second lever are provided in a further method step with another axle and in a last step, the third, now pivotally mounted on one of the axle third lever, be pivoted on the other axle bolts or clipped, so that the third lever is biased by stretching or compression to the first standard distance and retains this bias in the installed state.
- the receptacles of the axle in the third lever in the form of an axle hole and a recess and in a first method step
- the third lever between the first lever and the second lever is arranged, in a second method step, a first axle in a first axis hole of the first lever, a first axle hole of the second lever and an axle hole of the third lever is introduced, in a third step, a second axle in a second axle hole of the first lever ,
- a second axle hole of the second lever is introduced and in a fourth method step, the third lever is pivoted by a pivoting movement on the second axle bolt, being introduced by the pivoting of the axle in the recess of the third lever.
- axle bolts are in each case introduced axially into the receptacles of the levers in the form of axial bores.
- the receptacle for the axle pin in the form of a recess differs from the receptacles in the form of axle bores in that an axle bolt can also be introduced radially into the recess, for example by a pivoting movement of the corresponding lever.

Description
Die vorliegende Erfindung betrifft einen Stellarmantrieb für zumindest einen schwenkbar gelagerten Stellarm mit den Merkmalen des Oberbegriffs des Anspruchs 1, ein Möbel mit einem solchen Stellarmantrieb und ein Verfahren zur Herstellung eines solchen Stellarmantriebs. Ein Stellantrieb mit den Merkmalen des Oberbegriffs des Anspruchs 1 ist z.B. aus
Im Stand der Technik ist eine Vielzahl an Stellarmantrieben mit gelenkig miteinander verbundenen Hebeln bekannt. Um einen qualitativ hochwertig wirkenden, insbesondere spielfreien, Stellarmantrieb herstellen zu können, müssen die einzelnen Teile, dabei insbesondere die Teile der Hebel des Stellarmantriebs, mit hoher Präzision und Genauigkeit gefertigt werden. Einzelne Teile, die etwa durch Stanzen gefertigt werden können, und deren Verbindung untereinander können ausschlaggebend für die Qualität des zusammengestellten Stellarmantriebs sein, wobei oftmals ein Kompromiss zwischen herstellbarer Präzision der Bauteile und Zeit- und Fertigungsaufwand eingegangen werden muss. Komplizierte Verbindungen zwischen einzelnen Hebeln eines Stellarmantriebs können zudem zu einem erhöhten Materialaufwand und zu erhöhtem Raumbedarf führen.In the prior art, a variety of Stellarmantrieben with hingedly interconnected levers is known. In order to produce a high-quality acting, in particular backlash-free, Stellarmantrieb, the individual parts, especially the parts of the lever of Stellarmantriebs, must be manufactured with high precision and accuracy. Individual parts, which can be manufactured by punching about, and their connection with each other can be crucial for the quality of the assembled Stellarmantriebs, often a compromise between manufacturable precision of the components and time and manufacturing effort must be received. Complicated connections between individual levers of a Stellarmantriebs can also lead to increased material costs and increased space requirements.
Aufgabe der Erfindung ist die Bereitstellung eines Stellarmantriebs, bei welchem die zuvor genannten Nachteile nicht auftreten.The object of the invention is to provide a Stellarmantriebs, in which the aforementioned disadvantages do not occur.
Diese Aufgabe wird durch einen Stellarmantrieb mit den Merkmalen des Anspruchs 1, einem Möbel mit zumindest einem solchen Stellarmantrieb und ein Verfahren zur Herstellung eines solchen Stellarmantriebs gelöst. Vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen definiert.This object is achieved by a Stellarmantrieb with the features of
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass zumindest ein erster und ein zweiter Hebel des Stellarmantriebs parallel mit einem seitlichen Abstand zueinander angeordnet sind und die Hebel jeweils zwei Achsbohrungen mit einem ersten Normabstand aufweisen, durch die jeweils ein Achsbolzen hindurchragt, wobei ein dritter Hebel vorgesehen ist, der Aufnahmen für die Achsbolzen mit einem zweiten Normabstand aufweist, wobei der zweite Normabstand größer oder kleiner ist als der erste Normabstand und wobei die Achsbolzen jeweils durch die Achsbohrungen des ersten und des zweiten Hebels hindurchragen und in den Aufnahmen des dritten Hebels zumindest teilweise aufgenommen sind. Dadurch kann erreicht werden, dass der mittels Achsbolzen geschaffene Verbund aus dem ersten und dem zweiten Hebel durch Hinzunahme eines dritten Hebels stabilisiert wird. Unter einem ersten Normabstand kann dabei der gewünschte Abstand der Bohrungen zur Aufnahme der Achsbolzen im ersten und im zweiten Hebel verstanden werden, wobei sich der in der Produktion der Hebel ergebende tatsächliche Abstand der Achsbohrungen von dem Normabstand abweichen kann. Als Achsbolzen kann ein im Wesentlichen stift- oder zylinderförmiges Bauteil, beispielsweise ein Stahlstift, mit einem im Wesentlichen dem Durchmesser der Achsbohrungen entsprechendem Bauteildurchmesser verstanden werden. Der tatsächliche Durchmesser des Achsbolzens sowie der Achsbohrungen kann dabei in der Produktion jeweils von den gewünschten Durchmessern geringfügig abweichen. Dadurch, dass die jeweils durch die Achsbohrungen des ersten und des zweiten Hebels hindurchragenden Achsbolzen auch zumindest teilweise in den Aufnahmen des dritten Hebels, welche einen vom ersten Normabstand abweichenden zweiten Stand aufweisen, können etwaige in der Produktion auftretende Abweichungen ausgeglichen werden. Die Achsbolzen können dabei derart in den Aufnahmen und Achsbohrungen verspannt werden, dass es zu einem spielfreien Verbund des ersten und des zweiten Hebels mittels des dritten Hebels kommen kann.The object is achieved in that at least a first and a second lever of Stellarmantriebs are arranged parallel to each other with a lateral distance and the levers each have two axial bores with a first pitch, protrudes through each of which a pivot pin, wherein a third lever is provided , which has receptacles for the axle bolts with a second standard distance, wherein the second standard distance is greater or less than that first standard distance and wherein the axle bolts each protrude through the axial bores of the first and the second lever and are at least partially received in the receptacles of the third lever. It can thereby be achieved that the composite created by means of axle bolts is stabilized from the first and the second lever by the addition of a third lever. A first standard distance may be understood to mean the desired spacing of the bores for receiving the axle bolts in the first and in the second lever, wherein the actual distance of the axle bores resulting in the production of the levers may deviate from the standard distance. As an axle pin, a substantially pin-shaped or cylindrical component, for example a steel pin, can be understood as having a component diameter corresponding essentially to the diameter of the axle bores. The actual diameter of the axle pin and the axle bores may differ slightly in production from the desired diameters. Due to the fact that the axle bolts projecting respectively through the axle bores of the first and the second lever also at least partially in the receptacles of the third lever, which have a different second from the first standard distance, any deviations occurring in the production can be compensated. The axle bolts can be braced in such a way in the receptacles and axle bores that it can come to a play-free composite of the first and the second lever by means of the third lever.
Dabei kann vorteilhaft sein, dass der erste und der zweite Hebel im Wesentlichen flächig ausgebildet sind. Eine flächige Ausbildung der Hebel ist verfahrenstechnisch einfach, beispielsweise durch Stanzen, herstellbar und erleichtert auch das Anbringen der Achsbohrungen, welche auch in einem Ausstanzverfahren hergestellt werden können. Eine flächige Ausbildung der Hebel mit im Wesentlichen quer (normal) zu den Flächen verlaufenden Achsbolzen zur Verbindung der Hebel kann sich zudem durch vorteilhaft große Biegefestigkeit auszeichnen.It may be advantageous that the first and the second lever are formed substantially flat. A flat design of the lever is procedurally simple, for example by punching, produced and also facilitates the attachment of the axial bores, which can also be produced in a stamping process. A planar design of the lever with substantially transversely (normal) to the surfaces extending axle bolt for connecting the lever can also be characterized by advantageous large bending strength.
Auch kann dabei vorteilhaft sein, dass der erste und der zweite Hebel identisch ausgebildet sind. Dadurch kann ermöglicht werden, dass bei der Herstellung des Stellarmantriebs und insbesondere der Hebel keine Unterscheidung der mit dem ersten und dem zweiten Hebel korrespondierenden Bauteile und den zu deren Herstellung und Bearbeitung nötigen Werkzeugen gemacht werden muss.It may also be advantageous that the first and the second lever are identical. This makes it possible to make no distinction between the components corresponding to the first and the second lever and the tools necessary for their production and machining during the production of the actuating arm drive and in particular the lever.
Weiter kann vorteilhaft sein, dass der dritte Hebel im Wesentlichen flächig ausgebildet ist. Zum einen kann dadurch ein kompakter Verbund des ersten, zweiten und dritten Hebels ermöglicht werden. Zum anderen kann sich eine flächige Ausbildung des dritten Hebels insbesondere bei einer federelastischen Verformung des dritten Hebels zur zumindest teilweisen Aufnahme der Achsbolzen als vorteilhaft erweisen.Furthermore, it may be advantageous for the third lever to be substantially flat. On the one hand, this enables a compact combination of the first, second and third levers. On the other hand, a planar design of the third lever, in particular with a resilient deformation of the third lever for at least partially receiving the axle bolts prove to be advantageous.
Vorteilhaft kann sein, dass der dritte Hebel elastisch federnd ausgebildet ist. Dadurch kann der dritte Hebel zur zumindest teilweisen Aufnahme der jeweils durch die Achsbohrungen des ersten und des zweiten Hebels hindurchragenden Achsbolzen verformt werden. Durch eine dadurch auf die Achsbolzen ausgeübte Federkraft kann es vorteilhaft zu einem spielfreien Verspannen des Verbunds der Hebel kommen.It can be advantageous that the third lever is elastically resilient. As a result, the third lever for at least partially receiving the respectively projecting through the axle bores of the first and the second lever axle bolts are deformed. By thus exerted on the axle bolt spring force can advantageously come to a backlash-free clamping of the composite of the lever.
Weiter kann vorteilhaft sein, dass der dritte Hebel eine im Wesentlichen gekrümmte, vorzugsweise wellige, Form aufweist. Dadurch kann eine federelastische Verformbarkeit des Hebels erleichtert werden.Furthermore, it may be advantageous that the third lever has a substantially curved, preferably wavy, shape. As a result, a resilient deformability of the lever can be facilitated.
Dabei kann vorteilhaft sein, wenn der dritte Hebel eine Federkonstante in einem Bereich von 50 bis 250 N/mm, vorzugsweise in einem Bereich von 100 bis 150 N/mm (Newton pro Millimeter), aufweist. In anderen Worten gesagt kann es vorteilhaft sein, wenn der dritte Hebel bei einer Verformung, also bei einer Änderung des Abstands der Aufnahmen der Achsbolzen bei elastischer Verformung, um 1 mm eine Federkraft von 50 bis 250 Newton, vorzugsweise eine Federkraft von 100 bis 150 Newton, aufbringt. Eine Federkonstante in einem solchen Bereich stellt einen guten Kompromiss zwischen einfacher Montage und Spielausgleich einerseits und leichter Bewegbarkeit im Betrieb des Stellarmantriebs andererseits dar.It may be advantageous if the third lever has a spring constant in a range of 50 to 250 N / mm, preferably in a range of 100 to 150 N / mm (Newton per millimeter). In other words, it may be advantageous if the third lever at a deformation, ie a change in the distance of the shots of the axle with elastic deformation by 1 mm, a spring force of 50 to 250 Newton, preferably a spring force of 100 to 150 Newton , applies. A spring constant in such a range represents a good compromise between simple assembly and clearance compensation on the one hand and easier mobility in the operation of Stellarmantriebs other hand.
Auch kann vorteilhaft sein, dass die Aufnahmen der Achsbolzen im dritten Hebel in Form von Achsbohrung und/oder als Einbuchtung ausgebildet sind. Durch eine Ausbildung zumindest einer Aufnahme des dritten Hebels in Form einer Achsbohrung kann eine sichere und unverlierbare Verbindung mit den anderen Hebeln und einem durch Achsbohrungen dieser hindurchragenden Achsbolzen sichergestellt werden. Auch kann sich dadurch eine schwenkbare Lagerung des dritten Hebels an einem Achsbolzen ermöglichen lassen. Die Ausbildung zumindest einer der Aufnahmen des dritten Hebels in Form einer Einbuchtung keine lösbare Verbindung des dritten Hebels mit einem der Achsbolzen ermöglicht werden. Als Einbuchtung kann dabei eine zur zumindest teilweisen Aufnahme eines Achsbolzens geeignete Ausnehmung aus dem dritten Hebel verstanden werden. Eine solche Einbuchtung kann insbesondere von Vorteil sein, wenn der dritte Hebel nach bereits erfolgter Verbindung des ersten Hebels mit dem zweiten Hebel mittels der Achsbolzen erfolgen soll. Dabei kann beispielsweise ein mit einer Achsbohrung und einer Einbuchtung versehener dritter Hebel mit der Achsbohrung schwenkbar an einem der Achsbolzen gelagert sein und mit der Einbuchtung auf den zweiten Achsbolzen aufgeschwenkt bzw. aufgeklipst werden.It may also be advantageous for the receptacles of the axle bolts to be formed in the third lever in the form of an axle bore and / or as an indentation. By forming at least one receptacle of the third lever in the form of an axle bore, a secure and captive connection with the other levers and a through axial bores of this projecting axle bolts can be ensured. Also, this can allow a pivotable mounting of the third lever on a axle. Training at least one of the shots of the third lever in the form of a recess no releasable connection of the third lever with one of the axle bolts are allowed. In this case, a recess from the third lever which is suitable for at least partially receiving an axle bolt can be understood as indentation. Such a recess may be particularly advantageous if the third lever is to take place after the connection of the first lever to the second lever by means of the axle bolt. In this case, for example, provided with an axial bore and a recess third lever with the Achsbohrung pivotally mounted on one of the axle and be swung or clipped with the indentation on the second axle.
Auch kann vorteilhaft sein, dass der dritte Hebel - vorzugsweise im Wesentlichen vollständig - zwischen dem ersten und dem zweiten Hebel angeordnet ist. Durch eine Anordnung des dritten Hebels zwischen den anderen Hebeln kann dieser zumindest teilweise abgedeckt werden. Insbesondere kann es dabei bei einer federelastischen Verspannung des dritten Hebels zwischen den Achsbolzen zu einer im Wesentlichen symmetrischen Kraftausübung auf den ersten und den zweiten Hebel kommen.It may also be advantageous for the third lever-preferably substantially completely-to be arranged between the first and the second lever. By arranging the third lever between the other levers this can be at least partially covered. In particular, in the case of a spring-elastic tensioning of the third lever between the axle bolts, a substantially symmetrical application of force to the first and the second lever may occur.
Es kann weiter von Vorteil sein, dass der seitliche Abstand des ersten Hebels zum zweiten Hebel im Wesentlichen der Dicke des dritten Hebels entspricht. Dadurch kann ein besonders kompakter und stabiler Verbund der Hebel erreicht werden.It may also be advantageous that the lateral distance of the first lever to the second lever corresponds substantially to the thickness of the third lever. As a result, a particularly compact and stable composite of the levers can be achieved.
Es kann von Vorteil sein, dass die Abweichung des zweiten Normabstands zum ersten Normabstand in einem Bereich von 1 bis 10 %, vorzugsweise in einem Bereich von 5 bis 10 %, ist. Dadurch kann einerseits erreicht werden, dass es zu einem genügend großen Toleranzausgleich der in den Achsbohrungen gelagerten Achsbolzen kommt und andererseits auch vermieden werden, dass bei einer schwenkbaren Lagerung der Achsbolzen in den Achsbohrungen sich negativ auf den Betrieb des Stellarmantriebs auswirkende Reibungskräfte auftreten.It may be advantageous that the deviation of the second standard distance from the first standard distance is in a range of 1 to 10%, preferably in a range of 5 to 10%. This can be achieved on the one hand, that there is a sufficiently large tolerance compensation of the mounted in the axle bores axle and on the other hand also avoided that occur in a pivotal mounting of the axle in the Achsbohrungen negative impact on the operation of Stellarmantriebs frictional forces.
Es kann von Vorteil sein, dass die Abweichung des zweiten Normabstands zum ersten Normabstand in einem Bereich von 0,1 bis 5 mm, vorzugsweise in einem Bereich von 0,1 bis 1 mm, ist. Durch eine Abweichung in diesem Bereich kann einerseits sichergestellt werden, dass sich der gewünschte zweite Normabstand innerhalb der Fertigungstoleranzen herstellen lässt und andererseits kann durch eine Abweichung in diesem Bereich ein wirksamer Toleranzausgleich sichergestellt werden.It may be advantageous for the deviation of the second standard spacing from the first standard spacing to be in a range of 0.1 to 5 mm, preferably in a range of 0.1 to 1 mm. On the one hand, a deviation in this range can ensure that the desired second standard distance within the range Can manufacture manufacturing tolerances and on the other hand can be ensured by a deviation in this area an effective tolerance compensation.
Prinzipiell kann es von Vorteil sein, dass der zweite Normabstand größer ist als der erste Normabstand. Dabei kann der Abstand der Aufnahmen des dritten Hebels zur Aufnahme der durch die Achsbohrungen des ersten und des zweiten Hebels hindurchragenden Achsbolzen durch Stauchen im Wesentlichen auf den ersten Normabstand verringert werden - beispielsweise durch elastische Verformung des dritten Hebels - und es so zu einer Auseinanderspreizung der beiden Achsbolzen kommen. Vorzugsweise wird dabei die Abweichung des zweiten Normabstands zum ersten Normabstand derart gewählt, dass die Belastung der Achsbolzen der Hebel durch den dritten Hebel gleichgeartet ist, wie die Belastung auf die Achsbolzen durch die Gewichtskraft einer am Stellarmantrieb montierten Klappe in einer Montagelage des Stellarmantriebs.In principle, it may be advantageous for the second standard spacing to be greater than the first standard spacing. In this case, the distance of the receptacles of the third lever for receiving the projecting through the axle holes of the first and second pivot axle can be reduced by upsetting substantially to the first standard distance - for example, by elastic deformation of the third lever - and so it to a spread apart of the two Axle bolts come. Preferably, the deviation of the second standard distance to the first standard distance is selected such that the load of the axle of the lever is gleichgeartet by the third lever, as the load on the axle by the weight of a mounted on Stellarmantrieb flap in a mounting position of Stellarmantriebs.
Vorteilhaft kann sein, wenn das Verhältnis der Höhe des dritten Hebels zum zweiten Normabstand des dritten Hebels 0,35 oder weniger, bevorzugt 0,25 oder weniger, besonders bevorzugt 0,15 oder weniger, ist. Bevorzugt kann der dritte Hebel zumindest abschnittsweise ein solches Verhältnis zwischen der Höhe und dem Abstand der Aufnahmen aufweisen. Als Höhe des dritten Hebels kann dabei eine, zumindest abschnittsweise, im Wesentlichen quer zur Verbindungslinie der Aufnahmen der Achsbolzen (zweiter Normabstand) verlaufende Erstreckung des dritten Hebels verstanden werden.It can be advantageous if the ratio of the height of the third lever to the second standard distance of the third lever is 0.35 or less, preferably 0.25 or less, particularly preferably 0.15 or less. Preferably, the third lever at least in sections, such a ratio between the height and the distance of the recordings. In this case, the height of the third lever can be understood as an extension, extending at least in sections, substantially transversely to the connecting line of the receptacles of the axle bolts (second standard spacing) of the third lever.
Schutz wird auch begehrt für ein Möbel mit zumindest einem wie zuvor beschriebenen Stellarmantrieb.Protection is also desired for a piece of furniture with at least one actuating arm drive as described above.
Auch wird Schutz für ein Verfahren zur Herstellung eines wie zuvor beschriebenen Stellarmantriebs gesucht. Bei einem solchen Verfahren wird der dritte Hebel beim Zusammensetzen des Stellarmantriebs durch Dehnen oder Stauchen auf den ersten Normabstand vorgespannt, wobei er diese Vorspannung im eingebauten Zustand behält. Der dritte Hebel kann dabei beispielsweise eine Aufnahme in Form einer Achsbohrung und eine weitere Aufnahme in Form einer Einbuchtung aufweisen. Bei einem Herstellungsverfahren kann dabei der dritte Hebel in einem Verfahrensschritt zwischen dem ersten und dem zweiten Hebel angeordnet werden, die Hebel in einem weiteren Verfahrensschritt mit einem Achsbolzen durch die jeweiligen Achsbohrungen versehen werden, der erste und der zweite Hebel in einem weiteren Verfahrensschritt mit einem weiteren Achsbolzen versehen werden und in einem letzten Verfahrensschritt der dritte, nunmehr schwenkbar an einem der Achsbolzen gelagerte dritte Hebel, auf den weiteren Achsbolzen aufgeschwenkt bzw. aufgeklipst werden, sodass der dritte Hebel durch Dehnen oder Stauchen auf den ersten Normabstand vorgespannt wird und im eingebauten Zustand diese Vorspannung behält.Also, protection is sought for a method of manufacturing a servo arm drive as described above. In such a method, the third lever is biased during assembly of the Stellarmantriebs by stretching or upsetting to the first standard distance, while maintaining this bias in the installed state. The third lever may, for example, have a receptacle in the form of an axle bore and a further receptacle in the form of a recess. In a manufacturing process, the third lever can be used in one process step be arranged between the first and the second lever, the levers are provided in a further method step with a pivot pin through the respective axial bores, the first and the second lever are provided in a further method step with another axle and in a last step, the third, now pivotally mounted on one of the axle third lever, be pivoted on the other axle bolts or clipped, so that the third lever is biased by stretching or compression to the first standard distance and retains this bias in the installed state.
Anders gesagt kann bei einem solchen Verfahren zur Herstellung eines wie zuvor beschriebenen Stellarmantriebs vorgesehen sein, dass, die Aufnahmen der Achsbolzen im dritten Hebel in Form von einer Achsbohrung und einer Einbuchtung ausgebildet sind und in einem ersten Verfahrensschritt der dritte Hebel zwischen dem ersten Hebel und dem zweiten Hebel angeordnet wird, in einem zweiten Verfahrensschritt ein erster Achsbolzen in eine erste Achsbohrung des ersten Hebels, eine erste Achsbohrung des zweiten Hebels und die eine Achsbohrung des dritten Hebel eingebracht wird, in einem dritten Verfahrensschritt ein zweiter Achsbolzen in eine zweite Achsbohrung des ersten Hebels, eine zweite Achsbohrung des zweiten Hebels eingebracht wird und in einem vierten Verfahrensschritt der dritte Hebel durch eine Schwenkbewegung auf den zweiten Achsbolzen aufgeschwenkt wird, wobei durch das Aufschwenken der Achsbolzen in die Einbuchtung des dritten Hebels eingebracht wird. Die Achsbolzen werden dabei in die in Form von Achsbohrungen ausgebildeten Aufnahmen der Hebel jeweils axial eingebracht. Die Aufnahme für den Achsbolzen in Form einer Einbuchtung unterscheidet sich von den Aufnahmen in Form von Achsbohrungen darin, dass ein Achsbolzen auch radial in die Einbuchtung eingebracht werden kann, beispielsweise durch eine Schwenkbewegung des entsprechenden Hebels.In other words, in such a method for producing a Stellarmantriebs as described above, be provided that the receptacles of the axle in the third lever in the form of an axle hole and a recess and in a first method step, the third lever between the first lever and the second lever is arranged, in a second method step, a first axle in a first axis hole of the first lever, a first axle hole of the second lever and an axle hole of the third lever is introduced, in a third step, a second axle in a second axle hole of the first lever , A second axle hole of the second lever is introduced and in a fourth method step, the third lever is pivoted by a pivoting movement on the second axle bolt, being introduced by the pivoting of the axle in the recess of the third lever. The axle bolts are in each case introduced axially into the receptacles of the levers in the form of axial bores. The receptacle for the axle pin in the form of a recess differs from the receptacles in the form of axle bores in that an axle bolt can also be introduced radially into the recess, for example by a pivoting movement of the corresponding lever.
