Definitions

  • the invention relates to a furniture drive for moving a furniture front relative to a furniture body, comprising a base body to be fastened to the furniture body and an actuating arm, which is mounted on the base body so that it can rotate about at least a first axis of rotation, the actuating arm having a plurality of levers connected to one another in an articulated manner, with at least two the lever of the actuating arm can be detachably connected to the base body of the furniture drive.
  • the invention also relates to a piece of furniture with a furniture body, a furniture front and with at least one furniture drive of the type to be described, the base body of the at least one furniture drive being attached to the furniture body, preferably in and/or on a side wall of the furniture body, and the furniture front , preferably via a fastening interface, is fastened to the actuating arm of at least one furniture drive.
  • the invention relates to a method for mounting an actuating arm on a base body of a furniture drive of the type to be described.
  • Furniture drives of this type have a base body to be fastened to the furniture body and an actuating arm with at least two levers which are articulated to one another, the two levers of the actuating arm being connectable to two separate bearing points on the base body.
  • the separate design between the base body and the actuating arm has the advantage that the size of the furniture drive is divided into two assemblies and that these assemblies can be connected to one another in a modular manner.
  • a problem with the prior art is that adjusting arms with at least two levers for joint attachment to the base body can only be used on one side, ie only in combination with one to be attached to a first side of a furniture body first body of the furniture drive.
  • a second base body which is to be attached to an opposite side wall of the furniture body, however, a mirror image must be used trained actuator can be used. This is expensive to manufacture because two different production lines have to be provided for this in the factory.
  • handling is more complicated for a fitter on site because a distinction must always be made between "left" and "right” adjusting arms.
  • the applicant's AT 516783 A1 discloses a support device for a furniture flap.
  • the support device has two support arms which overlap without a gap in any position of the support device laterally to the direction of movement of the support device.
  • a first support arm can have a U-profile in which a second adjusting arm can be arranged.
  • the adjusting arms are permanently connected to a housing of the support device, with the axes of rotation of the support arms being located inside the housing and therefore not accessible.
  • Furniture drives for moving a furniture flap are disclosed in EP 3 321 461 A1 and US 2018/0298661 A1, wherein an actuating arm to be connected to the furniture flap can be detachably connected to a base body of the furniture drive.
  • the object of the present invention is to specify a furniture drive of the type mentioned at the outset while avoiding the disadvantages discussed above.
  • At least the levers of the actuating arm are arranged symmetrically to an imaginary center plane of the actuating arm.
  • the levers of the actuating arm Due to the symmetrical design of the levers of the actuating arm in relation to an imaginary center plane of the actuating arm, the levers can also be connected to a base body of a second furniture drive, which is to be fastened to an opposite side wall on the furniture body.
  • a single type of actuator arm for the two furniture drives to move the furniture front is required, with the manufacture and handling of the actuator arm is considerably simplified.

  • Fig. 10a-10c show the actuator arm in different views.
  • 1a shows a piece of furniture 1 with a furniture body 2 and with a movable furniture front 3 in the form of a furniture flap 3a that can be raised relative to the furniture body 2.
  • the furniture front 3 can be in one piece or, alternatively, can also comprise several furniture parts that can be moved together.
  • a furniture drive 4 for moving the movable furniture part 3 is fastened to opposite side walls of the furniture body 2 in each case.
  • the furniture drives 4 each have a rotatably mounted actuating arm 5 , a rotational movement of the two actuating arms 5 of the furniture drives 4 being able to be synchronized with one another by a synchronization shaft 6 .
  • FIG. 1b shows the piece of furniture 1 according to FIG. 1a with the furniture front 3 removed.
  • the two furniture drives 4 can be constructed in the same way, so that the explanations given here apply to both furniture drives 4 in each case.
  • the furniture drive 4 has a base body 9 which is to be fastened to the furniture carcass 2 and is preferably substantially cuboid, on which a lever 5a of the actuating arm 5 is pivotably mounted about an axis of rotation 7a.
  • the synchronization shaft 6, on the other hand, is rotatably mounted about a further axis of rotation 7c, the axis of rotation 7a of the lever 5a and the axis of rotation 7c of the synchronization shaft 6 being laterally offset from one another, preferably spaced parallel to one another.
  • the offset arrangement between the axis of rotation 7a of the lever 5a of the lever 5a and the axis of rotation 7c of the synchronization shaft 6 has the particular advantage that the synchronization shaft 6 can be arranged, for example, at a high point in the furniture body 2, i.e. close to a top panel 2a of the furniture body 2 .
  • the actuating arm 5 has a fitting part 8 which can be releasably connected to a fitting body (not shown) to be fastened to the furniture front 3 .
  • the fitting part 8 can be connected in an articulated manner to the lever 5a of the actuating arm 5 and can be designed in such a way that the fitting part 8 can be connected without tools to the fitting body to be fastened to the furniture front 3 .

  • the base body 9 of the furniture drive 4 has at least two separate bearing points 31a, 31b, which can be releasably connected to two separate connecting elements 32a, 32b of the actuating arm 5.
  • the actuating arm 5 has at least two or more levers 5a, 5b, 5c which are connected to one another in an articulated manner, the first connecting element 32a being arranged on a first lever 5a and a second connecting element 32b being arranged on a second lever 5b.
  • the third lever 5c which is preferably angled at an angle of about 90°, is to be connected to the furniture front 3.
  • a coupling piece 33 arranged on the first lever 5a is designed for connection to the synchronization shaft 6, a rotary movement of the coupling piece 33 being able to be synchronized via the synchronization shaft 6 with a coupling piece 33 of the furniture drive 4 lying opposite in the installed position.
  • Fig. 2b shows the actuating arm 5 according to the prior art in a connected state with the base body 9 of the furniture drive 4. It is immediately apparent from Fig. 2b that the actuating arm 5 according to the prior art due to its asymmetrical design only on one Page, in the present case, can only be used with a furniture drive 4 to be fastened on a right side wall of the furniture carcass 2. For a furniture drive 4 to be fastened to a left side wall of the furniture carcass 2, a mirror-inverted actuating arm 5 must be used.
  • Fig. 3a shows a furniture drive 4 according to the invention with an actuating arm 5 in an unconnected state with the base body 9.
  • the base body 9 of the furniture drive 4 has two parallel spaced housing walls 9a, 9b, each of which has a flat contact surface for contact with a Have furniture body 2.
  • the base body 9 of the furniture drive 4 can be mounted either on a first side wall of the furniture body 2 or alternatively on one of the second side walls of the furniture body 2 opposite the first side wall.
  • a front opening 9c is formed between the two housing walls 9a, 9b, through which the actuating arm 5 protrudes at least partially in a maximum open position.
  • the actuating arm 5 In a mounted state, the actuating arm 5 is mounted on the base body 9 such that it can rotate about at least a first axis of rotation 7a.
  • the actuating arm 5 comprises a plurality of levers 5a, 5b, 5c which are articulated to one another, at least two of the levers 5a, 5b of the actuating arm 5 being detachably connectable to the base body 9 of the furniture drive 4.
