Description

Antrieb für ein bewegbares Möbelteil Drive for a movable furniture part
Die vorliegende Erfindung betrifft einen Antrieb für ein bewegbares Möbelteil, insbesondere Möbelschublade, mit einer einen Ausstoßhebel aufweisenden Ausstoßvorrichtung und einem Elektromotor zum Antreiben des Ausstoßhebels.The present invention relates to a drive for a movable furniture part, in particular furniture drawer, with a discharge lever having a discharge device and an electric motor for driving the ejection lever.
Durch einen derartigen Antrieb ist es möglich, das bewegbare Möbelteil aus seiner geschlossenen Endlage in bzw. an einem Möbelkorpus in eine zumindest teilweise Offenstellung auszustoßen. Es ist jedoch nicht möglich, das bewegbare Möbelteil entgegen der Öffnungsrichtung zu bewegen, um es beispielsweise in die geschlossene Endlage überzuführen.By such a drive, it is possible to eject the movable furniture part from its closed end position in or on a furniture body in an at least partially open position. However, it is not possible to move the movable furniture part against the opening direction, for example, to transfer it to the closed end position.
Aufgabe der Erfindung ist es, einen gattungsgemäßen Antrieb derart weiterzubilden, dass seine Funktionalität erweitert wird, der Antrieb jedoch nicht aufwändiger zu montieren ist.The object of the invention is to develop a generic drive such that its functionality is expanded, but the drive is not expensive to assemble.
Diese Aufgabe wird durch einen Antrieb mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a drive with the features of claim 1.
Das Vorsehen einer Einzugsvorrichtung gestattet die Aufbringung von Kräften auf das bewegbare Möbelteil in Einzugsrichtung. Als Zugmittel bietet sich beispielsweise ein Seilzug an. Es können jedoch auch Zugmittel mit einer gewissen Steifigkeit (wie beispielsweise Metallbänder) vorgesehen sein.The provision of a collection device allows the application of forces to the movable furniture part in the feed direction. As pulling means, for example, offers a cable. However, traction means with a certain rigidity (such as metal bands) may also be provided.
Durch das mechanische Verbinden der Ausstoßvorrichtung und der Einzugsvorrichtung zu einer baulichen Einheit wird sichergestellt, dass der Antrieb mit den kombinierten Funktionalitäten gleich einfach zu montieren ist, wie ein Antrieb nach dem Stand der Technik, der nur eine Ausstoßvorrichtung aufweist.By mechanically connecting the ejection device and the retraction device to a structural unit, it is ensured that the drive with the combined functionalities is equally easy to assemble, as a drive according to the prior art, which has only one ejection device.
Beispielsweise kann hierzu vorgesehen sein, dass die Ausstoßvorrichtung und die Einzugsvorrichtung auf einer gemeinsamen Montageplatte angeordnet sind. Besonders bevorzugt ist jedoch eine Ausführungsform der Erfindung, bei welcher die Ausstoßvorrichtung und die Einzugsvorrichtung in einem gemeinsamen Gehäuse angeordnet sind. Besonders vorteilhaft ist es, wenn vorgesehen ist, dass das Gehäuse einen durch einen Hebel arretierbaren Bügel zur werkzeuglosen Befestigung des Antriebs an einer Profilschiene aufweist. Hierdurch wird ein besonders einfache Montage des Antriebs ermöglicht.For example, it can be provided for this purpose that the ejection device and the feed device are arranged on a common mounting plate. However, an embodiment of the invention in which the ejection device and the feed device are arranged in a common housing is particularly preferred. It when it is provided that the housing has a lockable by a lever bracket for tool-free attachment of the drive to a rail is particularly advantageous. This allows a particularly simple installation of the drive.
Grundsätzlich kann ein erfindungsgemäßer Antrieb für die Ausstoßvorrichtung und die Einzugsvorrichtung jeweils eigene Elektromotoren vorsehen.In principle, a drive according to the invention for the ejection device and the feed device can each provide its own electric motors.
In diesem Fall ist es günstig, wenn die Ausstoßvorrichtung und die Einzugsvorrichtung jeweils eigene Getriebe zur Kraftübertragung vom jeweiligen Elektromotor zum Ausstoßhebel bzw. der Rolle aufweisen, damit der Antriebstrang der Ausstoßvorrichtung und jener der Einzugsvorrichtung mechanisch voneinander getrennt bleiben.In this case, it is advantageous if the ejection device and the retraction device each have their own transmission for transmitting power from the respective electric motor to the ejection lever or the roller, so that the drive train of the ejection device and that of the retraction device mechanically separated from each other.
Eine Kopplung der Ausstoßvorrichtung und der Einzugsvorrichtung kann in einem solchen Fall durch eine gemeinsame Steuer- bzw. Regeleinheit auf elektronische Weise erfolgen.In such a case, a coupling of the ejection device and the feed device can be effected by a common control unit in an electronic manner.
Alternativ kann vorgesehen sein, dass der Ausstoßhebel der Ausstoßvorrichtung und die Rolle der Einzugsvorrichtung durch denselben Elektromotor antreibbar sind. Diese Ausführungsform weist den Vorteil auf, dass nur ein einziger Elektromotor pro Antrieb notwendig ist.Alternatively it can be provided that the ejection lever of the ejection device and the role of the feed device can be driven by the same electric motor. This embodiment has the advantage that only a single electric motor per drive is necessary.
Das Umschalten der Kraftübertragung vom Elektromotor auf den Ausstoßhebel der Ausstoßvorrichtung bzw. auf die Rolle der Einzugsvorrichtung kann durch verschiedenste Kupplungen erfolgen. Besonders bevorzugt ist jedoch eineThe switching of the power transmission from the electric motor to the ejection lever of the ejection device or to the role of the feed device can be done by a variety of couplings. However, especially preferred is one
Ausführungsform, bei welcher die Kraftübertragung vom Elektromotor über einEmbodiment in which the power transmission from the electric motor via a
Planetengetriebe wahlweise auf den Ausstoßhebel oder die Rolle erfolgt. Ein derartiges Planetengetriebe zeichnet sich durch eine besonders kompakte Bauweise aus, was insbesondere dann von Bedeutung ist, wenn die Ausstoßvorrichtung und diePlanetary gear either on the ejection lever or the role takes place. Such a planetary gear is characterized by a particularly compact design, which is particularly important when the ejector and the
Einzugsvorrichtung in einem gemeinsamen Gehäuse angeordnet sind.Feeding device are arranged in a common housing.
Bei dieser Ausführungsform kann vorgesehen sein, dass das Planetengetriebe zweistufig ausgebildet ist, wobei die eine Stufe der Kraftübertragung vom Elektromotor auf den Ausstoßhebel und die andere Stufe der Kraftübertragung vom Elektromotor auf die Rolle dient. Die Auswahl der jeweiligen Stufe kann über eine durch eine Steuerbzw. Regeleinrichtung schaltbare Bremse erfolgen, welche beispielsweise als Magnetbremse ausgebildet sein kann.In this embodiment, it may be provided that the planetary gear is formed in two stages, wherein the one stage of the power transmission from the electric motor to the ejection lever and the other stage of power transmission from the electric motor the role serves. The selection of the respective stage can via a Steuerbzw. Control device switchable brake done, which may be formed for example as a magnetic brake.
Jede der beiden Stufen des Planetengetriebes kann ein eigenes Hohlrad aufweisen, in welchem die jeweiligen Planetenräder aufgenommen sind, wobei die Bremse jeder Stufe mit dem jeweiligen Hohlrad zusammenwirkt. Durch das Feststellen des jeweiligen Hohlrades durch die jeweilige Bremse, kommt es zu einem Umlaufen der Planetenräder. Bei einer Ausführungsform der Erfindung ist vorgesehen, dass in der der Ausstoßeinheit zugeordneten Stufe die Kraftübertragung bei umlaufenden Planetenrädern erfolgt, hingegen in der der Rolle zugeordneten Stufe die Kraftübertragung bei feststehenden Planetenrädern erfolgt. Hierdurch können bei gleicher Drehrichtung des Elektromotors die zueinander entgegengesetzten Drehrichtungen des Ausstoßhebels und der Rollte verwirklicht werden.Each of the two stages of the planetary gear may have its own ring gear, in which the respective planet gears are accommodated, wherein the brake of each stage cooperates with the respective ring gear. By determining the respective ring gear by the respective brake, there is a revolution of the planetary gears. In one embodiment of the invention, it is provided that in the ejection unit associated stage, the power transmission takes place in orbiting planetary gears, however, in the role assigned to the stage, the power transmission takes place at fixed planetary gears. As a result, the mutually opposite directions of rotation of the ejection lever and the roller can be realized with the same direction of rotation of the electric motor.
Beispielsweise können für jede Stufe drei Planetenräder vorgesehen sein.For example, three planet gears may be provided for each stage.
Das Sonnenrad des Planetengetriebes wird in jeder Stufe durch eine gemeinsame Achse gebildet, welche durch den gemeinsamen Elektromotor antreibbar ist.The sun gear of the planetary gear is formed in each stage by a common axis, which is driven by the common electric motor.
Wie bereits ausgeführt kann in jeder der oben erwähnten Ausführungsformen eine gemeinsame Steuer- bzw. Regeleinrichtung zum Steuern bzw. Regeln der Ausstoßvorrichtung und der Einzugsvorrichtung vorgesehen sein.As already stated, in each of the above-mentioned embodiments, a common control device may be provided for controlling the ejection device and the intake device.
Diese Ausstoßvorrichtung kann in jeder Ausführungsform des Antriebs eine Touch- Latch-Funktionalität aufweisen. Dies bedeutet, dass die Ausstoßvorrichtung in der geschlossenen und/oder der teilweise oder vollständig geöffneten Endlage des bewegbaren Möbelteils durch eine Kraftausübung auf das Möbelteil auslösbar ist. Die hierfür notwendige Ausbildung der Ausstoßvorrichtung wurde bereits im österreichischen Patent AT 413 472 offenbart (siehe insbesondere Seite 4, Absätze 3 bis 7; Seite 7, Absätze 4 und 5; Seite 8, Absatz 6 sowie die darin bezeichneten Figuren), sodass eine nähere Beschreibung an dieser Stelle entfallen kann. Auch die Einzugsvorrichtung kann mit einer derartigen Touch-Latch-Funktionalität ausgestattet sein, sodass sich insgesamt ein Antrieb mit Touch-Latch-Funktionlität ergibt. Hierfür ist es notwendig, dass die Rolle in Aufwickelrichtung durch einen Kraftspeicher vorgespannt ist, damit das Zugmittel ständig unter mechanischer Spannung in Einzugseinrichtung gehalten wird. Hierdurch kann eine Kraftausübung auf das bewegbare Möbelteil durch einen Benutzer über das Zugmittel auf die Rolle übertragen werden und über geeignete Mittel (zum Beispiel Drehpotentiometer) detektiert werden.This ejection device may have a touch-latch functionality in any embodiment of the drive. This means that the ejection device in the closed and / or the partially or fully open end position of the movable furniture part can be triggered by a force on the furniture part. The necessary design of the ejection device has already been disclosed in the Austrian patent AT 413 472 (see in particular page 4, paragraphs 3 to 7, page 7, paragraphs 4 and 5, page 8, paragraph 6 and the figures therein), so that a more detailed description can be omitted at this point. Also, the collection device may be equipped with such a touch-latch functionality, so that the overall result is a drive with touch-latch functionality. For this purpose, it is necessary that the role in the winding direction is biased by a force storage, so that the traction means is constantly held under mechanical tension in intake device. In this way, a force can be transmitted to the movable furniture part by a user on the traction means on the role and be detected by suitable means (for example, rotary potentiometer).

Die Rolle 8 ist durch einen Kraftspeicher 24 in Aufwickelrichtung vorgespannt.The electric motor 7 drives the gear 14 via its worm. This is rotatably connected via the axis 15 with the gear 16. The gear 16 meshes with the gear 17, which in turn meshes with the gear 18. The gear 18 is rotatably connected to a square portion 19, which serves to transmit power to the roller 8. In this case, a Ruschkupplung 20 to 23 is connected between the square portion 19 and the roller 8, which is described in detail in the Austrian patent application A 1769/2006. This is a wrap spring clutch, the outer shell 22 is slightly braked by the spring 23, resulting in an immediate switching of the clutch. The roller 8 is biased by a force accumulator 24 in the winding.
Mit der Rolle 8 drehfest verbunden ist ein Schneckenaufsatz 25, welcher mit dem Antriebsrad 26 eines Dreh Potentiometers kämmt. Das Drehpotentiometer dient dabei der Positionsbestimmung der Rolle 8 zur Realisierung einer Touch-Latch-Funktionalität sowie der Position als bewegbares Möbelteil.With the roller 8 rotatably connected to a screw attachment 25 which meshes with the drive wheel 26 of a rotary potentiometer. The rotary potentiometer serves to determine the position of the roller 8 to realize a touch-latch functionality and the position as a movable furniture part.
In den Figuren 4a bis 4e ist der Antriebsstrang eines zweiten Ausführungsbeispiels eines erfindungsgemäßen Antriebs 1 dargestellt, wobei ein gemeinsamer Elektromotor 6 für den Ausstoßhebel 3 und die Rolle 8 vorgesehen ist (siehe Fig. 5).FIGS. 4a to 4e show the drive train of a second exemplary embodiment of a drive 1 according to the invention, a common electric motor 6 being provided for the ejection lever 3 and the roller 8 (see FIG. 5).
Dabei ist für die wahlweise Kraftübertragung auf den Ausstoßhebel 3 der Ausstoßvorrichtung bzw. die Rolle 8 der Einzugsvorrichtung ein Planetengetriebe 11 vorgesehen (siehe perspektivische Ansicht der Fig. 4a). Der Aufbau des Planetengetriebes 11 sei anhand der Fig. 4b in Zusammenschau mit den Fig. 5a bis 5c erläutert. Der Kraftfluss durch das Planetengetriebe 11 ist in den Fig. 4c bis 4e schematisch dargestellt.In this case, a planetary gear 11 is provided for the optional power transmission to the ejection lever 3 of the ejection device or the roller 8 of the retraction device (see perspective view of Fig. 4a). The structure of the planetary gear 11 will be explained with reference to FIG. 4b in conjunction with FIGS. 5a to 5c. The power flow through the planetary gear 11 is shown schematically in Figs. 4c to 4e.
Das Planetengetriebe 11 weist ein erstes Antriebsrad 27 auf, welches über die Zahnräder 28 und 29 durch die Schnecke 30 eines Elektromotors 6 antreibbar ist (siehe Fig. 5a).The planetary gear 11 has a first drive wheel 27, which can be driven via the gears 28 and 29 by the worm 30 of an electric motor 6 (see FIG. 5a).
Das Antriebsrad 27 ist drehfest auf der Achse 31 angeordnet, welche als Sonnenrad des Planetengetriebes 11 fungiert. An derselben Achse 31 ist ein Rad 32 angeordnet, welches über Bolzen 35 drei Planetenräder 34 (in Fig. 4b sind nur zwei Planetenräder 34 erkennbar) trägt. Zwischen dem Rad 32 und dem Zahnrad 27 ist einstückig mit dem Rad 32 ein Vierkantbereich 33 angeordnet, auf welchen der Ausstoßhebel 3 der Ausstoßvorrichtung zum Antreiben aufsteckbar ist. Gemeinsam mit dem einseitig gezahnten Hohlrad 36 wird die erste Stufe des Planetengetriebes 11 durch die Teile 32, 33, 34, 35 und 36 sowie der Achse 31 als Sonnenrad gebildet.The drive wheel 27 is rotatably arranged on the axis 31, which acts as a sun gear of the planetary gear 11. On the same axis 31, a wheel 32 is arranged, which via bolts 35 three planet gears 34 (in Fig. 4b only two planetary gears 34 are visible) carries. Between the wheel 32 and the gear 27, a square section 33 is integrally arranged with the wheel 32, on which the ejection lever 3 of the ejection device can be plugged for driving. Together with the one-sided toothed ring gear 36, the first stage of the planetary gear 11 is formed by the parts 32, 33, 34, 35 and 36 and the axis 31 as a sun gear.
Unterhalb des Hohlrades 36 ist ein weiteres Hohlrad 38 angeordnet, welches dreiBelow the ring gear 36, a further ring gear 38 is arranged, which three
Planetenräder 39 trägt (sichtbar sind nur zwei). Die Planetenräder 39 kämmen mit derPlanet wheels 39 carries (visible are only two). The planet gears 39 mesh with the
Innenverzahnung eines Rades 40, welches einstückig mit der Rolle 8 ausgebildet ist und mit dem drehfest mit der Achse 31 verbundenen Zahnrad 37. Das Rad 40 weist weiters eine Außenverzahnung 41 auf, welche über ein Zahnrad 42 und ein Zahnrad 43 mit einem nicht dargestellten Drehpotentiometer kämmt (siehe Fig. 5a).Internal toothing of a wheel 40 which is formed integrally with the roller 8 and with the rotatably connected to the axis 31 gear 37. The wheel 40 points Furthermore, an outer toothing 41, which meshes via a gear 42 and a gear 43 with a rotary potentiometer, not shown (see Fig. 5a).
Die zweite Stufe des Planetengetriebes 11 wird durch die Bauteile 37, 38, 39 und 40 und der Achse 31 als Sonnenrad gebildet,The second stage of the planetary gear 11 is formed by the components 37, 38, 39 and 40 and the axis 31 as a sun gear,
Die Funktionalität des Planetengetriebes 11 sei insbesondere auch mit Blick auf die Fig. 4c bis 4e erklärt. Der besseren Erkennbarkeit halber wurden dabei in den Figuren 4d und 4e nur jeweils die relevanten Bauteile mit Bezugszeichen versehen.The functionality of the planetary gear 11 is explained in particular also with regard to FIGS. 4c to 4e. For better visibility, only the relevant components have been provided with reference numerals in FIGS. 4d and 4e.
Fig. 4d zeigt die Kraftübertragung vom Elektromotor 6 auf den Ausstoßhebel 3 der Ausstoßvorrichtung. Die Krafteinleitung erfolgt über das Antriebsrad 27 auf die Achse 31. Die der ersten Stufe des Planetengetriebes 11 zugeordnete Bremse 44 (in Fig. 5a nicht erkennbar, da sie sich auf der nicht einsehbaren Rückseite befindet) bremst über eine Schlingfeder 45 das Hohlrad 36 der ersten Stufe. Dadurch kommt es zu einem Umlauf der Planetenräder 34 im Hohlrad 36 unter Kämmung mit der inneren Verzahnung. Über die Bolzen 35 wird dadurch das Rad 32 und der darauf aufgeordnete Vierkantbereich 33 gedreht. Hierdurch kommt es zu einem Antreiben des Ausstoßhebels 3 der Ausstoßvorrichung.Fig. 4d shows the power transmission from the electric motor 6 to the ejection lever 3 of the ejector. The force is applied via the drive wheel 27 on the axis 31. The first stage of the planetary gear 11 associated brake 44 (not visible in Fig. 5a, since it is located on the non-visible rear) brakes via a wrap spring 45, the ring gear 36 of the first Step. This results in a circulation of the planetary gears 34 in the ring gear 36 under mesh with the internal teeth. By means of the bolts 35, the wheel 32 and the square section 33 arranged thereon are thereby rotated. This leads to a driving of the ejection lever 3 of the ejection device.
Währenddessen bleibt die Bremse 44 der zweiten Stufe inaktiv. Das Hohlrad 38 der zweiten Stufe kann sich gemeinsam mit den daran befestigten Planetenrädern 39 dadurch frei drehen und es kommt zu keiner Kraftübertragung auf das Rad 40 und die Rolle 8.Meanwhile, the second stage brake 44 remains inactive. The ring gear 38 of the second stage can rotate freely together with the planetary gears 39 attached thereto and there is no transmission of power to the wheel 40 and the roller 8.
Anders ist die Situation in Fig. 4e. Hier ist die Bremse 44 (siehe Fig. 5a) der zweiten Stufe aktiv und drückt die Schlingfeder 46 gegen das Hohlrad 38. Durch das fixierte Hohlrad 38 bleiben die Planetenräder 39 ortsfest und kämmen einerseits mit dem durch die Achse 31 angetriebenen Zahnrad 37 und andererseits mit der Innenverzahnung des Zahnrades 40. Hierdurch wird die Antriebskraft vom Zahnrad 37 (Sonnenrad) über die Planetenräder 39 auf das Zahnrad 40 und damit auf die Rolle 8 übertragen. Die erste Stufe (Kraftübertragung auf den Ausstoßhebel 3) weist also während der Kraftübertragung umlaufende Planetenräder 34 auf, wodurch das die Planetenräder 34 über die Bolzen 35 tragende Rad 32 in Bewegung gesetzt wird.The situation is different in Fig. 4e. Here, the brake 44 (see Fig. 5a) of the second stage is active and presses the wrap spring 46 against the ring gear 38. By the fixed ring gear 38, the planet gears 39 remain stationary and mesh on the one hand with the axis driven by the shaft 31 gear 37 and on the other As a result, the driving force from the gear 37 (sun gear) via the planetary gears 39 is transmitted to the gear 40 and thus to the roller 8. The first stage (power transmission to the ejection lever 3) thus has during the power transmission revolving planet gears 34, whereby the planetary gears 34 via the bolts 35 bearing wheel 32 is set in motion.
Im Gegensatz dazu weist die zweite Stufe (für die Rolle 8) während der Kraftübertragung ortsfeste Planetenräder 39 auf, da ja das Hohlrad 38, an welchem die Planetenräder 39 gelagert sind, durch die Schlingfeder 46 fixiert wird. In diesem Fall kommt es zur Kraftübertragung von der Achse 31 und dem Zahnrad 37 über die Planetenräder 39 auf das Rad 40. Die Drehrichtung ist jedoch im Vergleich zur ersten Stufe umgedreht. Dies ist auch zu verlangen, da ja die Antriebsrichtung für die Ausstoßung bzw. den Einzug eines bewegbaren Möbelteils bei unveränderter Drehrichtung der Achse 31 entgegensetzt zueinander sein müssen.In contrast, the second stage (for the roller 8) during power transmission fixed planetary gears 39, since the ring gear 38, on which the planet gears 39 are mounted, is fixed by the wrap spring 46. In this case, there is power transmission from the axis 31 and the gear 37 via the planetary gears 39 to the wheel 40. The direction of rotation is, however, reversed compared to the first stage. This is also to be demanded, since the drive direction for the ejection or the entry of a movable furniture part must be opposite to one another with the direction of rotation of the axle 31 unchanged.
Von Interesse ist noch der Aufbau der Bremse 44, welcher aus den Fig. 5b und 5 c hervorgeht. Erkennbar ist, dass die Bremse 44 einen Stößel 47 aufweist, welcher bei Aktivierung der Bremse 44 auf die zugeordnete Schlingfeder 45 bzw. 46 drückt. In diesem Ausführungsbeispiel sind die Bremsen 44 als Magnetbremsen ausgebildet. Of interest is still the structure of the brake 44, which is apparent from Figs. 5b and 5 c. It can be seen that the brake 44 has a plunger 47 which, upon activation of the brake 44, presses on the associated wrap spring 45 or 46. In this embodiment, the brakes 44 are designed as magnetic brakes.
