- ein Gehäuse mit einer am Möbelkorpus zu befestigenden ersten Gehäusewand und mit einer von der ersten Gehäusewand zumindest bereichsweise beabstandeten zweiten Gehäusewand,  a housing having a housing wall to be fastened to the furniture body and having a second housing wall spaced at least in regions from the first housing wall,

- wobei wenigstens die erste Gehäusewand wenigstens eine Führungsvorrichtung zur Führung eines Befestigungsmittels aufweist.  - 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. Furthermore, the invention relates to a piece of furniture with a furniture body, a relative to the furniture body movably mounted furniture part and 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 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 WO 2017/059471 A1 a furniture fitting in the form of a furniture drive for moving furniture flaps is shown in Figs. 5a, 5b, wherein the furniture fitting can be mounted by a fastening device to a furniture body. The fastening device has two fastening elements, which can be inserted in a common cylindrical bore and moved by rotation of a locking element in an expanded position, so that the fastening elements are held in the spread position within the bore by frictional engagement. In DE 20 2016 101 285 U1 a furniture drive for moving furniture flaps is disclosed, wherein the furniture drive has a recess for receiving a pin. In a first assembly step, the pin is pre-mounted on a furniture body, in a subsequent assembly step, the furniture drive is locked by inserting the preassembled pin into the recess with the pin, whereby the furniture drive is to attach 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 DE 10 2007 049 143 A1 discloses a furniture fitting for mounting on a chipboard is disclosed, wherein in a broadened to the chipboard towards the mouth of the Furniture fitting a support body is arranged. The support body is designed to receive a screw and is in the assembled state of the chipboard, so that in the mouth space, the risk of tearing the screw and breaking out of the wood material is reduced from the chipboard.

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 on a guide device (for example, a hole or a cylindrical portion) for guiding and / or receiving the fastening means. When screwing the housing to the furniture body and / or moving heavy furniture parts, it may happen that the housing deformed by the forces occurring, twisted or lowered. In this case takes place between the two housing walls, an undesirable relative movement, whereby the joint axes of the furniture drive offset relative to each other and the friction forces are increased massively. This can eventually lead in some cases to the fact that the movable furniture part is not or only more difficult to operate by 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. Object of the present invention is to provide a furniture drive of the type mentioned above while avoiding the disadvantages discussed above.
