The present invention relates to a furniture drive for moving a furniture part mounted movably relative to a furniture body, comprising:
  • a housing with a first housing wall to be fastened to the furniture body and with a second housing wall which is at least partially spaced apart from the first housing wall,
  • wherein at least the first housing wall has at least one guide device for guiding a fastening means.

Im Weiteren betrifft die Erfindung ein Möbel mit einem Möbelkorpus, einem relativ zum Möbelkorpus bewegbar gelagerten Möbelteil und mit einem Möbelantrieb der zu beschreibenden Art.The invention also relates to a piece of furniture with a furniture body, a furniture part mounted so as to be movable relative to the furniture body, and with a furniture drive of the type to be described.

In der WO 2017/059471 A1 ist in den Fig. 5a, 5b ein Möbelbeschlag in Form eines Möbelantriebes zum Bewegen von Möbelklappen gezeigt, wobei der Möbelbeschlag durch eine Befestigungsvorrichtung an einem Möbelkorpus montierbar ist. Die Befestigungsvorrichtung weist zwei Befestigungselemente auf, welche in einer gemeinsamen zylindrischen Bohrung einsteckbar und durch Drehung eines Arretierelementes in eine Spreizstellung bewegbar sind, sodass die Befestigungselemente in der Spreizstellung innerhalb der Bohrung durch Reibschluss gehalten sind.In the WO 2017/059471 A1 is in the Figures 5a, 5b a furniture fitting shown in the form of a furniture drive for moving furniture flaps, wherein the furniture fitting can be mounted on a furniture body by a fastening device. The fastening device has two fastening elements which can be inserted into a common cylindrical bore and can be moved into an expanded position by rotating a locking element, so that the fastening elements are held in the expanded position within the bore by frictional engagement.

In der DE 20 2016 101 285 U1 ist ein Möbelantrieb zum Bewegen von Möbelklappen offenbart, wobei der Möbelantrieb eine Ausnehmung zur Aufnahme eines Zapfens aufweist. In einem ersten Montageschritt wird der Zapfen an einem Möbelkorpus vormontiert, in einem nachfolgenden Montageschritt wird der Möbelantrieb durch Einführen des vormontierten Zapfens in die Ausnehmung mit dem Zapfen verriegelt, wodurch der Möbelantrieb am Möbelkorpus zu befestigen ist.In the DE 20 2016 101 285 U1 a furniture drive for moving furniture flaps is disclosed, the furniture drive having a recess for receiving a pin. In a first assembly step the pin is pre-assembled on a furniture body, in a subsequent assembly step the furniture drive is locked by inserting the pre-assembled pin into the recess with the pin, whereby the furniture drive is to be attached to the furniture body.

In der DE 10 2007 049 143 A1 ist ein Möbelbeschlag zur Montage an einer Spanplatte offenbart, wobei in einem zur Spanplatte hin verbreiterten Mündungsraum des Möbelbeschlages ein Stützkörper angeordnet ist. Der Stützkörper ist zur Aufnahme einer Schraube ausgebildet und liegt im Montagezustand an der Spanplatte an, sodass im Mündungsraum die Gefahr eines Ausreißens der Schraube und ein Herausbrechen des Holzmaterials aus der Spanplatte reduziert wird.In the DE 10 2007 049 143 A1 a furniture fitting for mounting on a chipboard is disclosed, wherein in a widened to the chipboard mouth of the Furniture fitting a support body is arranged. The support body is designed to accommodate a screw and in the assembled state rests against the chipboard, so that the risk of the screw tearing out and the wood material breaking out of the chipboard is reduced in the mouth space.

Die WO2013/029070 A1 offenbart auch einen gattungsgemäßen Möbelantrieb.the WO2013 / 029070 A1 also discloses a generic furniture drive.

Das Gehäuse solcher Möbelantriebe wird üblicherweise an einem Möbelkorpus durch Befestigungsmittel (beispielsweise durch Schrauben) montiert. Hierfür weist das Gehäuse des Möbelantriebes eine Führungsvorrichtung (beispielsweise ein Loch oder einen zylindrischen Abschnitt) zur Führung und/oder Aufnahme des Befestigungsmittels auf. Bei der Verschraubung des Gehäuses am Möbelkorpus und/oder bei Bewegen von schweren Möbelteilen kann es vorkommen, dass sich das Gehäuse durch die auftretenden Kräfte verformt, verwindet oder absenkt. Dabei findet zwischen den beiden Gehäusewänden eine unerwünschte Relativbewegung statt, wodurch die Gelenkachsen des Möbelantriebes relativ zueinander versetzt und die Reibungskräfte massiv erhöht werden. Dies kann in manchen Fällen schließlich dazu führen, dass das bewegbare Möbelteil durch die Hemmungen des Möbelantriebes nicht oder nur mehr schwergängig zu betätigen ist.The housing of such furniture drives is usually mounted on a furniture body by fastening means (for example by screws). For this purpose, the housing of the furniture drive has a guide device (for example a hole or a cylindrical section) for guiding and / or receiving the fastening means. When the housing is screwed onto the furniture body and / or when heavy furniture parts are moved, it can happen that the housing is deformed, twisted or sunk by the forces that occur. An undesirable relative movement takes place between the two housing walls, as a result of which the hinge axes of the furniture drive are offset relative to one another and the frictional forces are massively increased. In some cases, this can ultimately lead to the movable furniture part not being able to be operated or only difficult to operate due to the inhibitions of the furniture drive.

Aufgabe der vorliegenden Erfindung ist es, einen Möbelantrieb der eingangs erwähnten Gattung unter Vermeidung der oben diskutierten Nachteile anzugeben.The object of the present invention is to specify a furniture drive of the type mentioned at the beginning while avoiding the disadvantages discussed above.

Dies wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Weitere Ausführungsbeispiele der Erfindung sind in den abhängigen Patentansprüchen angegeben.This is achieved according to the invention by the features of claim 1. Further exemplary embodiments of the invention are specified in the dependent claims.

Gemäß der Erfindung ist demnach vorgesehen, dass wenigstens ein Stützkörper vorgesehen ist, welcher von der wenigstens einen Führungsvorrichtung zur Führung des Befestigungsmittels gesondert ausgebildet ist, welcher die wenigstens eine Führungsvorrichtung zumindest bereichsweise umgibt und welcher sowohl mit der ersten Gehäusewand als auch mit der zweiten Gehäusewand fest verbunden ist, sodass eine Bewegung der zweiten Gehäusewand relativ zur ersten Gehäusewand gehemmt ist.According to the invention it is therefore provided that at least one support body is provided which is formed separately from the at least one guide device for guiding the fastening means, which surrounds the at least one guide device at least partially and which is fixed to both the first housing wall and the second housing wall is connected, so that a movement of the second housing wall is inhibited relative to the first housing wall.

Mit anderen Worten ist zur Stabilisierung des Gehäuses wenigstens ein Stützkörper vorgesehen, welcher zwischen der ersten und zweiten Gehäusewand angeordnet ist und welcher sowohl mit der ersten Gehäusewand als auch mit der zweiten Gehäusewand fest verbunden ist. Die Führungsvorrichtung zur Aufnahme und/oder Führung des Befestigungsmittels ist dabei von dem wenigstens einen Stützkörper zumindest bereichsweise umgeben, sodass die Führungsvorrichtung durch den Stützkörper stabilisiert und von den restlichen Bereichen der Gehäusewand weitgehend entkoppelt ist. Auf diese Weise werden die Gehäusewände relativ zueinander stabilisiert, sodass auch die parallele Lage der Gelenkachsen des Möbelantriebes zueinander beibehalten wird.In other words, to stabilize the housing, at least one support body is provided which is arranged between the first and second housing walls and which is firmly connected to both the first housing wall and the second housing wall. The guide device for receiving and / or guiding the fastening means is at least partially surrounded by the at least one support body, so that the guide device is stabilized by the support body and largely decoupled from the remaining areas of the housing wall. In this way, the housing walls are stabilized relative to one another, so that the parallel position of the joint axes of the furniture drive to one another is maintained.

Gemäß einem Ausführungsbeispiel kann vorgesehen sein, dass der wenigstens eine Stützkörper V-förmig oder U-förmig ausgebildet ist. Der wenigstens eine Stützkörper kann wenigstens zwei Schenkel aufweisen, welche zueinander einen, vorzugsweise spitzen, Winkel zueinander einschließen.According to one embodiment it can be provided that the at least one support body is V-shaped or U-shaped. The at least one support body can have at least two legs which enclose a preferably acute angle to one another.

Gemäß einem weiteren Ausführungsbeispiel kann vorgesehen sein, dass der wenigstens eine Stützkörper die Führungsvorrichtung über einen Winkelbereich von wenigstens 180° umgibt.According to a further exemplary embodiment, it can be provided that the at least one support body surrounds the guide device over an angular range of at least 180 °.

Der wenigstens eine, vorzugsweise aus einem Metall bestehende, Stützkörper kann mit der ersten Gehäusewand und/oder mit der zweiten Gehäusewand verschweißt, vernietet oder vertaumelt sein.The at least one support body, preferably made of a metal, can be welded, riveted or tumbled to the first housing wall and / or to the second housing wall.

Fig. 1a zeigt eine perspektivische Darstellung eines Möbels 1, wobei ein bewegbares Möbelteil 3 durch einen Möbelantrieb 4 um eine horizontal verlaufende Drehachse relativ zu einem Möbelkorpus 2 schwenkbar gelagert ist. Durch den Möbelantrieb 4 ist das bewegbare Möbelteil 3 ausgehend von einer vertikalen Schließstellung in eine relativ zum Möbelkorpus 2 angehobene Lage (und in die umgekehrte Richtung) bewegbar. Der Möbelantrieb 4 weist ein am Möbelkorpus 2 zu befestigendes Gehäuse 5 mit einer ersten Gehäusewand 5a und zumindest einen relativ zum Gehäuse 5 schwenkbar gelagerten Stellarm 6 zum Bewegen des bewegbaren Möbelteiles 3 auf. Zur Kraftbeaufschlagung des Stellarmes 6 ist eine Federvorrichtung 7 vorgesehen, welche die Gewichtskraft des Möbelteiles 3 zumindest teilweise kompensiert und die Öffnungsbewegung des bewegbaren Möbelteiles 3 für einen Benutzer unterstützt wird. Der Stellarm 6 ist durch eine Rastvorrichtung 23 (Fig. 1b) mit einem am bewegbaren Möbelteil 3 zu befestigenden Beschlagteil 22 lösbar verrastbar. Fig. 1a shows a perspective view of a piece of furniture 1, a movable furniture part 3 being mounted so as to be pivotable relative to a furniture body 2 about a horizontal axis of rotation by a furniture drive 4. By means of the furniture drive 4, the movable furniture part 3 can be moved, starting from a vertical closed position, into a position raised relative to the furniture body 2 (and in the opposite direction). The furniture drive 4 has a housing 5 to be fastened to the furniture body 2 with a first housing wall 5 a and at least one actuating arm 6, which is pivotably mounted relative to the housing 5, for moving the movable furniture part 3. To apply force to the actuating arm 6, a spring device 7 is provided which at least partially compensates for the weight of the furniture part 3 and supports the opening movement of the movable furniture part 3 for a user. The actuating arm 6 is secured by a latching device 23 ( Figure 1b ) can be releasably latched to a fitting part 22 to be fastened to the movable furniture part 3.

Fig.1b zeigt den Möbelantrieb 4 gemäß einem möglichen Ausführungsbeispiel. An der ersten Gehäusewand 5a ist die Federvorrichtung 7 (beispielsweise zumindest eine als Schraubenfeder ausgebildete Druckfeder) gelagert, welche sich an einer ortsfesten Gelenkachse A abstützt und gegen die Gelenkachse B drückt. Die Gelenkachse B ist an einem ersten Hebelende eines zweiarmigen Umlenkhebels 9 gelagert, welcher um die Gelenkachse C drehbar gelagert ist. Das zweite Hebelende des Umlenkhebels 9 steht über die Gelenkachse D mit einem Schubhebel 10 in Verbindung, welcher über einen Bolzen 11 mit einem um eine Drehachse E drehbaren Schwenkhebel 12 gelenkig verbunden ist. Durch Betätigung einer Einstellvorrichtung 13 ist der Abstand des Bolzens 11 entlang einer Führung des Schwenkhebels 12 relativ zur Gelenkachse E und damit der wirksame Hebelarm zwischen dem Bolzen 11 und der Gelenkachse E veränderbar, sodass ein auf den Stellarm 6 ausgeübtes Drehmoment der Federvorrichtung 7 entsprechend dem jeweiligen Gewicht des bewegbaren Möbelteiles 3 einstellbar ist. Der Schwenkhebel 12 ist über die Gelenkachsen F, G mit einem ersten Hebel 8 und einem zweiten Hebel 14 gelenkig verbunden, wobei der erste Hebel 8 und der zweite Hebel 14 über die Gelenkachsen H, I mit dem Stellarm 6 gelenkig verbunden sind. Fig.1b shows the furniture drive 4 according to a possible embodiment. The spring device 7 (for example at least one compression spring designed as a helical spring) is mounted on the first housing wall 5a and is supported on a stationary hinge axis A and presses against the hinge axis B. The hinge axis B is mounted on a first lever end of a two-armed reversing lever 9, which is mounted rotatably about the hinge axis C. The second lever end of the reversing lever 9 is connected via the hinge axis D to a thrust lever 10, which is connected in an articulated manner via a bolt 11 to a pivot lever 12 which can be rotated about an axis of rotation E. By actuating an adjusting device 13, the distance of the bolt 11 along a guide of the pivot lever 12 relative to the hinge axis E and thus the effective lever arm between the bolt 11 and the hinge axis E can be changed, so that a torque of the spring device 7 exerted on the actuating arm 6 corresponds to the respective Weight of the movable furniture part 3 is adjustable. The pivot lever 12 is articulated to a first lever 8 and a second lever 14 via the articulation axes F, G, the first lever 8 and the second lever 14 being articulated to the actuating arm 6 via the articulation axes H, I.

Fig. 2 zeigt den Möbelantrieb 4 in einer perspektivischen Ansicht. Das Gehäuse 5 weist eine erste Gehäusewand 5a zur Anlage am Möbelkorpus 2 und eine zweite Gehäusewand 5b auf, wobei die erste Gehäusewand 5a und die zweite Gehäusewand 5b zumindest bereichsweise voneinander beabstandet sind. Durch erste und zweite Befestigungsmittel 16a und 16b, beispielsweise in Form von Schrauben, ist die erste Gehäusewand 5a am Möbelkorpus 2 zu befestigen, wobei die zweite Gehäusewand 5b über zumindest einen oder mehrere Stützkörper 21a, 21b (Fig. 3) an der ersten Gehäusewand 5a gehalten ist. Die Gehäusewände 5a, 5b können - abgesehen von spiegelbildlich ausgebildeten Komponenten - baugleich ausgeführt sein, sodass die hier vorgebrachten Ausführungen zur ersten Gehäusewand 5a jeweils auch für die zweite Gehäusewand 5b (und umgekehrt) gelten. Ein derartiger symmetrischer Aufbau des Möbelantriebes 4 hat den Vorteil, dass der Möbelantrieb 4 neben einer einfachen Herstellung auch wahlweise an einer linken oder an einer rechten Seitenwand eines Möbelkorpus 2 zu befestigen ist. Die Gehäusewände 5a, 5b weisen jeweils mehrere voneinander beabstandete Vorsprünge 15a-15h zur Anlage am Möbelkorpus 2 auf, sodass also ein Großteil der Gehäusewände 5a, 5b im Montagezustand des Möbelantriebes 4 vom Möbelkorpus 2 beabstandet ist. Fig. 2 shows the furniture drive 4 in a perspective view. The housing 5 has a first housing wall 5a for contact with the furniture body 2 and a second housing wall 5b, the first housing wall 5a and the second housing wall 5b being at least partially spaced from one another. The first housing wall 5a is to be fastened to the furniture body 2 by first and second fastening means 16a and 16b, for example in the form of screws, the second housing wall 5b via at least one or more support bodies 21a, 21b ( Fig. 3 ) is held on the first housing wall 5a. The housing walls 5a, 5b can - apart from mirror-inverted components - be constructed identically, so that the statements made here on the first housing wall 5a also apply to the second housing wall 5b (and vice versa). Such a symmetrical structure of the furniture drive 4 has the advantage that the furniture drive 4, in addition to being simple to manufacture, can also be optionally attached to a left or right side wall of a furniture body 2. The housing walls 5a, 5b each have a plurality of spaced-apart projections 15a-15h for contact with the furniture body 2, so that a large part of the housing walls 5a, 5b is spaced apart from the furniture body 2 when the furniture drive 4 is installed.
