Definitions

  • the present invention relates to a drive device for a movable furniture part, in particular for a furniture flap, with a carrier that can be fastened to a furniture body, an actuating arm device that is movably mounted on the carrier and can be connected to the movable furniture part, an energy store with which the actuating arm device can be subjected to a force, a damping device with which a closing movement and an opening movement of the actuating arm device can be damped, and an adjustment device with which the damping device can be adjusted in terms of a damping force, in a damping start position in relation to an angular position of the actuating arm device relative to the carrier and/or in terms of a damping path.
  • the invention relates to a piece of furniture with such a drive device.
  • Drive devices with actuating arm devices are primarily used in furniture flaps, which can be pivoted upwards about a horizontal axis to open them. General examples of this can be found in WO 2012/155165 A2 and WO 2011/020130 A1.
  • a damping device is also described in the second document, which dampens the movement of the furniture flap moving in the closing direction.
  • EP 2 607 592 A2 also discloses a furniture fitting with a damping device which damps a closing movement of the furniture flap.
  • the damper has an impact surface, the impact surface being in a damping start position in the absence of an applying member. Adjustment means for adjusting the damping start position are assigned to the damper. This starting position can thus be adjusted with this furniture fitting, but this furniture fitting is not suitable for damping an opening movement of the furniture flap.
  • EP 1 707 723 A2 shows an actuating arm drive for flaps, with a damper producing a damping effect before the upper end position is reached and before the lower end position is reached.
  • a stop arranged on the actuating arm presses on the first end of the damper, while at the end of the opening path a linearly movable carriage presses on a second end of the damper.
  • the damping path and the damping performance of the damper are adjustable.
  • WO 2020/112058 A2 also shows a furniture fitting for a furniture flap, with which the end sections of the closing movement and the opening movement can be damped.
  • damping devices that are separate from one another and arranged at different points are provided for the respective damping movement.
  • the object of the present invention is to provide an alternative or improved drive device.
  • the disadvantages of the prior art are to be avoided at least in part.
  • the drive device should be as compact, simple and versatile as possible.
  • the adjustment device comprises at least one adjustment means, which is coupled to the damping device in such a way that an adjustment of the damping force, the damping start position and/or the damping path made by the adjustment device occurs both during damping of the actuating arm device during the course of the closing movement as well as in the course of the opening movement damping of the actuating arm device by means of the damping device.
  • the adjustment device can be used to lengthen or shorten the damping path. This means that this adjustment can be made directly in the damping device.
  • the damping force of the damping device can be changed accordingly and adapted to the weight of the furniture flap to be moved.
  • the damping start position can be adjusted with the adjustment device and can therefore be changed. Specifically, this means that by changing the damping start position there is also a changed angular position of the furniture flap at the beginning of the damping movement. The start of damping can therefore take place at a different or changed angular position of the furniture flap.
  • the damping device can be acted upon by the actuating arm device from the same side both during an opening movement and during a closing movement. So there is no need for a complicated redirection of movement in order to act on the damping device “from behind”, so to speak.
  • the damping device can be designed as a spring or as another elastic damping element. However, it is preferably provided that the damping device is designed as a fluid damper.
  • the damping device has a damper housing, a damper piston that can be moved relative to the damper housing, and a damping means, preferably a damping fluid arranged in a fluid chamber, for damping a relative movement between the damper housing and damper piston.
  • the actuating arm device bears against the damper piston during a damping movement of a furniture part. That moment or that position in which or in which the actuating arm device contacts the damper piston or bears against it or begins to act on it is the damping start position.
  • the damping piston moves relative to the carrier (fixed to the furniture carcass).
  • the damping housing can be movable relative to the carrier during a furniture part damping movement and/or during an adjustment movement. According to a first exemplary embodiment, it can be provided that the damper housing can be pivoted and moved translationally relative to the carrier.
  • the damper housing can be displaced relative to the carrier, preferably linearly.
  • the relative position between the damper housing and the carrier can be adjusted with the adjusting device.
  • the setting can be stepless via the setting device.
  • the relative position between the damper housing and the carrier can be adjusted with the adjustment device by switching a switch that can be actuated without tools between two positions.
  • a preferred embodiment provides that the actuating arm device can be moved between a first maximum position, which corresponds to the closed position between the movable furniture part and the furniture body, and a second maximum position, which corresponds to the maximum open position of the movable furniture part relative to the furniture body.
  • the damping device it is possible for the damping device to dampen the entire movement path of the actuating arm device. However, it is preferably provided that the damping takes place via the damping device in a movement section of the movable furniture part upstream of the closed position and the maximum open position.
  • the (respectively) upstream movement section corresponds to a pivoting angle range of the actuating arm device (and thus indirectly of the movable furniture part) of between 2° and 25°, preferably between 5° and 15°.
  • the actuating arm device has a transmission mechanism for transmitting a force from the force accumulator to an actuating arm of the actuating arm device.
  • the actuating arm device has at least one damping transmission element (preferably two separate damping transmission elements), which can be moved with the actuating arm device and, during a furniture part damping movement, abuts against the damping device, preferably against its damping piston, via a stop.

  • the force accumulator is arranged between the carrier and the actuating arm device and is effective between the carrier and the actuating arm device.
  • the drive device has an ejection device for ejecting the movable furniture part from the closed position into an open position.
  • the energy accumulator can be designed, for example, as a gas pressure spring. It is preferably provided that the force accumulator is designed as a spring, preferably as a compression spring. The energy accumulator can also be designed as a spring assembly.

  • the damping device 7 can be adjusted relative to the carrier 4 via the adjusting device 8 .
  • the adjustment device 8 has the adjustment means 8a (in the form of a switch) and the adjustment pivot pin 8x.
  • the adjusting axle pin 8x is firmly connected to the carrier 4.
  • the adjustment means 8a is pivoted to the right, as a result of which the damping device 7 is in a right-hand maximum position relative to the carrier 4.
  • a first damping transmission element 5a is formed on the actuating arm 52 .
  • This first damping transmission element 5a is designed in the form of an extension which faces the damping device 7 .
  • the stop 55 is (still) at a distance from the counterpart stop 74 formed on the damper housing 71.
  • a stop element 56 (in the form of a roller) is arranged on the actuating arm device 5 .
  • This stop element 56 is (still) at a distance from the second damping transmission element 5b, which is pivotably mounted on the carrier 4 via the axle pin 57.
  • the actuating arm device 5 is in the same open position. This corresponds to an approximately half-open movable furniture part 2.
  • the opening angle of the actuating arm 52 is somewhere in the range between 55° and 80°.
  • FIGS. 4a and 4b differ in that the damping device 7 is in different positions.
  • the damping device 7 is in its right maximum position.
  • the adjustment means 8a is rotated to the right about the adjustment pivot pin 8x.
  • FIGS. 5a and 5b A comparison between FIGS. 5a and 5b shows that the damper housing 71 has also carried out a (slight) pivoting movement relative to the carrier 4 in addition to a translatory displacement movement relative to the carrier 4 .
  • the actuating arm 52 assumes a different angular position at the damping start position D given in each case. Specifically, an opening angle of approximately 108° is given in FIG. 6a, while an opening angle of 100° is given in FIG. 6b.
  • the movement section of the movable furniture part 2 upstream of the maximum opening position OS is thus damped, with the damping start position D being set differently via the setting device 8 . This allows different opening angles to be set for the start of the damping movement.
  • the actuating arm 52 assumes a different angular position at the damping start position D given in each case. Specifically, in FIG. 7a there is an opening angle of approximately 22°, while in FIG. 7b there is an opening angle of just under 33°.
  • the second damping transmission element 5b is rotated counterclockwise about the pivot pin 57 via the stop element 56, as a result of which the damping transmission element 5b presses on the damper piston 72 via the stop 58 and pushes it into the damper housing 71 , which in turn causes the damping device 7 to exert its effect.
  • the closed position SS is reached (not shown).
  • Figs. 8a and 8b the damping device 7 is shown without the other components of the drive device 1 in a longitudinal section.
  • the damper piston 72 is retracted, which means that the damping end position has been reached. (The internal structure of the damping device 7 is not described in detail since this corresponds to a fluid damper known per se.)
  • FIG. 9a and 9b show another embodiment of an adjusting device 8.
  • the damping device 7 is adjustably mounted in the support 4.
  • the adjusting axle pin 8x of the adjusting device 8 is firmly connected to the carrier 4.
  • the adjusting means 8a is designed as a wing-like extension on the damper housing 71.
  • the damper housing 71 has depressions 8b and 8c of different depths on its end face, which are arranged transversely (preferably at right angles) to one another.
  • the adjustment pivot pin 8x is in the deeper recess 8c, as a result of which the damping device 7 is in its left-hand maximum position.
  • FIG. 10a shows a further exemplary embodiment of a damping device 7, in which case a spacer piece, which can preferably be inserted manually, is used as the adjustment means 8a.
  • a spacer piece which can preferably be inserted manually
  • FIGS. 11a to 11c A further exemplary embodiment is shown in FIGS. 11a to 11c.
  • the basic mode of operation is the same as in the previously described exemplary embodiments, which is why the description of most of the components is not repeated again.
  • This exemplary embodiment according to FIGS. 11a to 11c differs in that the damper housing 71 is mounted on the carrier 4 so that it can only be displaced linearly.
  • FIG. 11a the actuating arm 52 has approximately the same position as in FIG. 6b.
  • FIG. 11b the position of the actuating arm 52 corresponds approximately to that of FIG. 6a.
  • the damper housing 71 in FIGS. 11a and 11b is in different positions relative to the carrier 4 (and the adjustment axle pin 8x arranged on the carrier 4) via the adjustment device 8, as a result of which different damping start positions D are given.
  • FIG. 11c the drive device 1 is shown in section along a longitudinal plane, as a result of which details of the damper housing 71 can be seen. Specifically, a guide surface 76 is formed on the damper housing 71, via which the damper housing 71 rests on the guide element 75 arranged on the carrier 4. The damper housing 71 can slide linearly along the guide element 75 via the guide surface 76 .
  • the first damping transmission element 5a and the second damping transmission element 5b which are each in contact with the damper housing 71, can also be seen in detail at the top left.
