Description

Drive device for a movable furniture part

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. In addition, 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. In this case, 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.

In contrast, 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. When closing, 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. In this document, however, 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. In particular, 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.

This is solved by a drive device with the features of claim 1. Accordingly, it is provided according to the invention that 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.

According to a variant, 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.

Alternatively, the damping force of the damping device can be changed accordingly and adapted to the weight of the furniture flap to be moved.

Alternatively—and particularly preferred—it is provided that 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.

In a particularly simple and uncomplicated exemplary embodiment, it is provided that 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.

According to a particularly preferred exemplary embodiment, it is provided that 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.

Furthermore, it is preferably provided that 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.

Provision can be made for the damper housing to be fixed relative to the carrier during a furniture part damping movement. Thus, during the damping movement of the furniture part, only the damping piston moves relative to the carrier (fixed to the furniture carcass).

Provision can be made for the damping housing to 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.

Alternatively, it can be provided that the damper housing can be displaced relative to the carrier, preferably linearly.

For changing the damping force, the damping path or the damping start position, it is provided that the relative position between the damper housing and the carrier can be adjusted with the adjusting device.

It is possible for the setting to be stepless via the setting device. Alternatively (and particularly preferably) it is provided that 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.

In principle, 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.

Specifically, it can be provided that 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°. As is known per se, it is provided that 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.

Provision is particularly preferably made for the transmission mechanism to have a control cam and a pressure roller loaded by the force accumulator, the pressure roller being movable along the control curve when the at least one actuating arm is moved.

Furthermore, it is preferably provided that 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.

Specifically, there are two preferred variants, which can be implemented in a drive device, specifically to allow the damping device to be acted upon from the same side.

Accordingly, it is provided that a first damping transmission element is arranged or formed on the actuating arm, with the opening movement of the actuating arm device being dampable via this first damping transmission element, preferably in a movement section of the movable furniture part upstream of the maximum opening position.

Provision is also made for a second damping transmission element to be movably, preferably rotatably, mounted on the carrier and at least in sections to be movably coupled to the transmission mechanism, with the closing movement of the actuating arm device being able to be damped via this second damping transmission element, preferably in a movement section of the movable furniture part upstream of the closed position. For a compact design, it is provided that the force accumulator is arranged between the carrier and the actuating arm device and is effective between the carrier and the actuating arm device.

According to a preferred exemplary embodiment, it is provided that the drive device has an ejection device for ejecting the movable furniture part from the closed position into an open position.

Provision is particularly preferably made for the ejection device to have a locking device which can be unlocked by pushing the movable furniture part into a pushing-over position which is behind the closed 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.

Protection is also sought for a piece of furniture with a furniture body, a furniture part movably mounted on the furniture body, preferably in the form of a furniture flap, and a drive device according to the invention.

According to a preferred exemplary embodiment, it is provided that a drive device is arranged on two opposite side walls of the furniture body, which drive device can drive the same movable furniture part via their respective actuating arm devices.

Further details and advantages of the present invention are explained in more detail below on the basis of the description of the figures with reference to the exemplary embodiments illustrated in the drawings. Show in it:

1 shows a piece of furniture 100 with a furniture body 3, a drive device 1 (furniture fitting) for moving a movably mounted furniture part 2 being fastened to a side wall 3a of the furniture body 3.

In the exemplary embodiment shown, the movable furniture part 2 has two furniture flaps 2a, 2b, with a first furniture flap 2a being pivotable about a horizontal axis of rotation with the furniture body 3 via at least two hinges 9a and the second furniture flap 2b being pivotable about a horizontal axis of rotation via at least two hinges 9b is pivotally connected to the first furniture flap 2a.

The drive device 1 has a support 4 to be fastened to the furniture body 3, preferably to the side wall 3a of the furniture body 3, and at least one actuating arm 52 which can be pivoted relative to the support 4 and which is connected to the movable furniture part 2, preferably to the second furniture flap 2b . It can be seen that the piece of furniture 100 in FIG. 1 is arranged at a distance from the ceiling 10 of the room. In FIG. 1, the actuating arm 52 assumes a relatively large pivoting angle, which corresponds to the maximum open position OS of the movable furniture part 2.

2a shows the drive device 1 in a side view, the drive device 1 having a support 4 to be fastened to the furniture body 3 and at least one actuating arm 52 which is pivotably mounted on the support 4 about an axis of rotation X.

In the exemplary embodiment shown, an actuating arm extension 11 is detachably arranged on the actuating arm 52, the actuating arm extension 11 having two actuating arm parts 11a, 11b which can be displaced relative to one another. Provision is preferably made for the actuating arm parts 11a, 11b to be telescopically displaceable relative to one another, with the first actuating arm part 11a being detachably connectable to the actuating arm 52. The second actuating arm part 11b has a fastening device 12 which can be releasably connected to a fitting part to be fastened to the movable furniture part 2, preferably locked and unlocked without tools.

For the application of force to the actuating arm 52 of the actuating arm device 5, a force accumulator 6 is provided which, for example, can have at least one helical spring, preferably at least one compression spring. Alternatively, the energy accumulator 6 can also have other energy accumulators, such as a fluid accumulator in the form of a gas pressure spring.

The actuating arm device 5 has a transmission mechanism 51 for transmitting a force from the force accumulator 6 to the at least one actuating arm 52 . Provision is preferably made for the transmission mechanism 51 to have a control cam 53 and a pressure roller 54 loaded by the energy accumulator 6, with the pressure roller 54 being movable along the control curve 53 when the at least one actuating arm 52 moves. According to a preferred exemplary embodiment, the cam 53 can be arranged or formed on the actuating arm 52 . It is of course also possible to arrange the control cam 53 at a different point in the transmission mechanism 51 of the actuating arm device 5 .

A force of the force accumulator 6 on the at least one actuating arm 52 can be adjusted by a force adjustment device 14 . It is preferably provided that

- The force adjustment device 14 has at least one rotatably mounted adjustment wheel 14a, wherein a force of the energy accumulator 6 acting on the at least one adjustment arm 52 can be adjusted on the adjustment arm 52 by rotating the adjustment wheel 14a, and/or

- The force setting device 14 has at least one threaded spindle 16, along which a point of application 15 of the force accumulator 6 can be moved when the force setting device 14 is actuated and/or

- The carrier 4 has an end face with at least one opening 17a through which the at least one actuating arm 52 protrudes in an open position, wherein an adjustment wheel 14a of the force adjustment device 14 can be actuated from a direction transverse to the end face through the opening 17a.

Fig. 2b shows the area circled in Fig. 2a in an enlarged view. The transmission mechanism 51 has an intermediate lever 19 which is mounted on the carrier 4 so that it can pivot about an axis of rotation 19a. The threaded spindle 16 is mounted on the intermediate lever 19. The threaded spindle 16 can be rotated by turning the setting wheel 14a of the force setting device 14 by means of a tool, as a result of which the point of application 15 of the force accumulator 6 moves along the threaded spindle 16 . In this way, the relative distance between the point of application 15 and the axis of rotation 19a of the intermediate lever 19 and thus the torque of the force accumulator 6 acting on the actuating arm 52 can be increased or decreased.

The drive device 1 also includes at least one damping device 7 for damping a movement of the at least one actuating arm 52 of the actuating arm device 5. It is preferably provided for the damping device 7 that it

- Is designed as a fluid damper and / or - Has at least one piston-cylinder unit and/or

- Can be acted upon by the at least one actuating arm 52 during a closing movement and/or

- Can be acted upon from the same side both during an opening movement O and during a closing movement S of the at least one actuating arm 52 .

3a shows the drive device 1 in a perspective view, with a force of the energy accumulator 6 being able to be transmitted to the at least one actuating arm 52 by the transmission mechanism 51 of the actuating arm device 5 . The force setting device 14 can, for example, comprise a rotatable setting wheel 14a, the point of application 15 of the force accumulator 6 being adjustable along the threaded spindle 16 by rotating the setting wheel 14a and thus the torque acting on the setting arm 52.

The drive device 1 can also have an assembly safety device 20 for the empty actuating arm 52, on which no movable furniture part 2 is mounted, to limit the opening speed of the empty actuating arm 52, the assembly safety device 20 preventing the empty actuating arm 52 from being opened or deflected unintentionally by a Power of the energy store 6 prevented. It is preferably provided that the assembly lock 20 comprises at least one centrifugal clutch 20a.

3b shows the drive device 1 in a further (slightly offset) perspective view. The entire damping device 7 can be clearly seen in this representation. This damping device 7 has the damper housing 71 and the damper piston 72.

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.

In FIG. 3b, 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. It can be seen in FIG. 3b that 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 . In the position shown in Fig. 3b, 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.

4a to 7b each show a vertical longitudinal section through the drive device in different positions.

In FIGS. 4a and 4b 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°.

However, FIGS. 4a and 4b differ in that the damping device 7 is in different positions. In Fig. 4b, the damping device 7 is in its right maximum position. As can be seen in the associated enlarged representation according to FIG. 5b, the adjustment means 8a is rotated to the right about the adjustment pivot pin 8x. As a result, there is a relatively wide area of the adjustment means 8a between the damper housing 71 and the adjustment pivot 8x.

In contrast, in FIG. 4a and in the associated FIG. 5a, the adjustment means 8a of the adjustment device is rotated by 90° to the left. As a result, there is a relatively narrow area of the adjustment means 8a between the damper housing 71 and the adjustment axle pin 8x. The damping device 7 is in its left maximum position. In all positions according to FIGS. 4a to 5b the damping device is unloaded and thus relaxed and in the fully extended position. The second pressure transmission element 5b is in contact with the damping piston 72 .

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 .

Starting from the previous FIGS. 4a to 5b, an opening movement 0 of the actuating arm device 5 was carried out in FIGS. 6a and 6b. As a result, the actuating arm 52 has been pivoted upwards. This opening movement 0 was carried out until the stop 55 of the first damping transmission element 5a made contact with the counterpart stop 74 . In this position, the damping start position D is reached.

Since the damping devices 7 are in different maximum positions in FIGS. 6a and 6b, 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.

If the opening movement O is continued from this respective damping start position D, the damper piston 72 is pushed into the damper housing 71 via the stop counterpart 74, as a result of which the damping device 7 unfolds its effect. As soon as the damper piston 72 is fully retracted, the maximum open position OS is reached (not shown).

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 same principle also applies to the closing movement S. Starting from FIGS. 4a to 5b, a closing movement S of the actuating arm device 5 was carried out in FIGS. 7a and 7b. As a result, the actuating arm 52 has been pivoted downwards. This closing movement S was carried out until the stop element 56 made contact with the second damping transmission element 5b as a result of the rotary movement of the actuating arm 52 about the axis of rotation X. In this position, the damping start position D is reached.

Since the damping devices 7 are in different maximum positions in FIGS. 7a and 7b, 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°.

If the closing movement S is continued from this respective damping starting position D, 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. As soon as the damper piston 72 is fully retracted, the closed position SS is reached (not shown).

In 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.)

9a and 9b show another embodiment of an adjusting device 8. In turn, the damping device 7 is adjustably mounted in the support 4. FIG. 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. In Fig. 9a and in the associated detail, 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.

In FIG. 9b, the damper housing 71 was rotated manually about the longitudinal axis by approximately 90° using the adjustment means 8a. As a result, the adjustment pivot pin 8x is now in the less deep depression 8b, as a result of which the damping start position D is adjusted accordingly.

Finally, 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. As a result, the right-hand maximum position is reached in FIG. 10a.

In Fig. 10b this adjustment means 8a of the adjustment device 8 has been removed, whereby the adjustment pivot pin 8x has moved further in the direction of the damper housing 71 and the left maximum position is given, which in turn corresponds to a damping start position at a different opening angle.

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.

In FIG. 11a the actuating arm 52 has approximately the same position as in FIG. 6b. In 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. In 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.
