[0004] - At least one adjusting device, by means of which the position of the at least one adjusting arm at its maximum open position can be adjusted.

[0005] Furthermore, the present invention relates to a type of furniture having a furniture body, furniture components movably supported relative to the furniture body, particularly a furniture flap, and a furniture drive device of the type to be described for moving the movably supported furniture components. Background Technology

[0006] The aforementioned adjustment device of the furniture drive mechanism can adjust the maximum opening position of the adjustment arm and thus the maximum opening position of the furniture parts connected to the adjustment arm. By limiting the maximum opening position of the adjustment arm, it is possible to prevent the movable furniture parts from colliding with adjacent cabinets or the room ceiling.

[0007] WO 2017 / 219055 A1 discloses a furniture accessory for moving a movablely supported furniture flap, wherein an adjusting device is provided for limiting the maximum opening angle of an adjusting arm to be connected to the furniture flap. The adjusting arm is pivotally supported relative to a carrier to be fixed to the furniture body by a plurality of levers. The adjusting device for limiting the maximum opening angle of the adjusting arm includes an operating element rotatably supported on a first lever and supported on a second lever. A disadvantage is that two levers movable relative to each other must be provided. Therefore, it is desirable that the adjusting device can also be applied to furniture drive mechanisms with only one control arm. Summary of the Invention

Attached Figure Description

[0064] Further details and advantages of the invention are illustrated with reference to the embodiments shown in the accompanying drawings. The drawings are as follows:

[0065] Figures 1a-1c A furniture drive mechanism fixed to the furniture body is shown, wherein at least one adjusting arm has a different maximum open position;

[0066] Figure 2a , 2b The furniture drive mechanism is shown in a side view, along with a magnified detail view of it.

[0067] Figure 3a , 3b A perspective view showing the furniture drive mechanism and a magnified detail view thereof;

[0068] Figures 4a-4cAn adjustment device is shown for adjusting the position of the adjustment arm at its maximum open position, wherein the adjustment arm is located in different maximum open positions;

[0069] Figures 5a-5d The image shows the adjusting arm in two different maximum open positions, along with a magnified detail view of them.

[0070] Figure 6a , 6b A furniture drive device according to a slightly modified embodiment is shown, wherein the pivoting component is in two different positions. Detailed Implementation

[0071] Figures 1a-1c The furniture 1 shown has a furniture body 2, and a furniture drive device 4 is fixed on the side wall 2a of the furniture body 2 for moving furniture parts 3 that are movably supported.

[0072] In the illustrated embodiment, the movable furniture component 3 has two furniture flaps 3a and 3b, wherein the first furniture flap 3a is pivotally connected to the furniture body 2 via at least two hinges 7a about a horizontally extending rotation axis, and the second furniture flap 3b is pivotally connected to the first furniture flap 3a via at least two hinges 7b about a horizontally extending rotation axis.

[0073] The furniture drive device 4 has a support member 5 to be fixed to the furniture body 2, preferably on the side wall 2a of the furniture body 2, and at least one adjusting arm 6 that can pivot relative to the support member 5, the adjusting arm being connected to a movable furniture component 3, preferably to a second furniture flap 3b.

[0074] It can be seen that, Figures 1a-1c The furniture 1 occupies a different height relative to the room ceiling 8. Figure 1a In the middle, furniture 1 is at its lowest position relative to the room ceiling 8. Figure 1b In the middle position, and in Figure 1c It occupies the highest position in the middle. Therefore, in Figure 1a The middle adjusting arm 5 occupies the largest pivot angle relative to the load-bearing member 5. Figure 1b It occupies the middle pivot angle, and in Figure 1c It occupies the smallest pivot angle.

[0075] To prevent the movable furniture parts 3 from colliding with the room ceiling 8, the furniture drive mechanism 4 has an adjustment device 9, which will also be described later. Figure 3b The maximum opening position of the adjusting arm 6 can be adjusted and limited by this adjusting device. In this way, the maximum opening position of the adjusting arm 6 can be adapted to... Figures 1a-1c The installation is shown in the image.

[0076] Figure 2a The furniture drive device 4 is shown in a side view. The furniture drive device 4 has a support member 5 to be fixed to the furniture body 2 and at least one adjusting arm 6, which is pivotally supported on the support member 5 about a rotation axis 6a.

[0077] In the illustrated embodiment, the adjusting arm extension 11 is detachably disposed on the adjusting arm 6, and the adjusting arm extension 11 has two adjusting arm components 11a and 11b that are movable relative to each other. Preferably, the adjusting arm components 11a and 11b are telescopically movable relative to each other, wherein the first adjusting arm component 11a is detachably connected to the adjusting arm 6. The second adjusting arm component 11b has a fixing device 12, which is detachably connected to an accessory to be fixed to the movable furniture component 3, and preferably can be locked and unlocked without tools.

[0078] To apply force to the adjusting arm 6, a spring device 10 is provided, which may have at least one helical spring, preferably at least one compression spring. Alternatively, the spring device 10 may also have other accumulators, such as a fluid accumulator in the form of a pneumatic spring.

[0079] The furniture drive device 4 has a transmission mechanism 13 for transmitting the force of the spring device 10 to the at least one adjusting arm 6. Preferably, the transmission mechanism 13 has a control curve 13a and a pressure roller 13b loaded by the spring device 10, the pressure roller 13b being movable along the control curve 13a when the at least one adjusting arm 6 moves.

[0080] According to a preferred embodiment, the control curve 13a can be set or constructed on the adjusting arm 6. Of course, the control curve 13a can also be set on other parts of the transmission mechanism 13.

[0081] The force exerted by the spring device 10 on the at least one adjusting arm 6 can be adjusted by the force adjusting device 14, preferably the force adjusting device 14:

[0082] - An adjusting wheel 14a having at least one rotatably supported, the force exerted by the spring device 10 on the at least one adjusting arm 6 can be adjusted by the rotation of the adjusting wheel 14a, and / or

[0083] -Having at least one lead screw 16, the actuating part 15 of the spring device 10 can move along the lead screw when the force adjusting device 14 is operated, and / or

[0084] - The support member 5 has an end face 17 with at least one opening 17a. Figure 3bThe at least one adjusting arm 6 extends through the opening 17a in the open position, wherein the adjusting wheel 14a of the force adjusting device 14 is accessible from a direction transverse to the end face 17 (X, Figure 3b It is operated through the opening 17a.

[0085] Figure 2b Shown in enlarged view Figure 2a The area circled in the center. The transmission mechanism 13 has an intermediate lever 19, which is pivotally supported on the carrier 5 about a rotation axis 19a. A lead screw 16 is supported on the intermediate lever 19. The lead screw 16 can be rotated by means of the adjusting wheel 14a of the tool turning power adjusting device 14, thereby moving the actuating part 15 of the spring device 10 along the lead screw 16. In this way, the relative distance between the actuating part 15 and the rotation axis 19a of the intermediate lever 19, and therefore the torque exerted by the spring device 10 on the adjusting arm 6, can be increased or decreased.

[0086] The furniture drive unit 4 further includes at least one damping device 18 for damping the movement of the at least one adjusting arm 6, preferably the damping device 18:

[0087] - Constructed as a fluid damper, and / or

[0088] -Having at least one piston-cylinder unit, and / or

[0089] - During the closing motion, loading can be achieved via at least one adjusting arm 6, and / or

[0090] - Loading can be applied from the same side not only during the opening movement of the at least one adjusting arm 6 but also during the closing movement.

[0091] Figure 3a The furniture drive unit 4 is shown in perspective, wherein the force of the spring device 10 is transmitted to the at least one adjusting arm 6 via the transmission mechanism 13. The force adjustment device 14 may include, for example, a rotatable adjusting wheel 14a, wherein the actuating part 15 of the spring device 10 and thus the torque acting on the adjusting arm 6 can be adjusted along the lead screw 16 by rotating the adjusting wheel 14a.

[0092] The furniture drive unit 4 may also have a mounting safety device 20 for the empty adjusting arm 6 (on which no movable furniture part 3 is yet mounted) to limit the opening speed of the empty adjusting arm 6, wherein the mounting safety device 20 prevents the empty adjusting arm 6 from being accidentally opened or removed by the force of the spring device 10. Preferably, the mounting safety device 20 includes at least one centrifugal clutch 20a.

[0093] Figure 3b Shown in magnified view Figure 3aThe area framed in the middle shows in detail the adjusting device 9 used to adjust the position of the at least one adjusting arm 6 to its maximum open position.

[0094] The adjusting device 9 has at least one pivoting member 21 that is movable relative to the at least one adjusting arm 6 to at least two pivoting positions, wherein when the at least one adjusting arm 6 is in the maximum open position, the at least one pivoting member 21 spacees the at least one adjusting arm 6 from at least one stop 22 provided on the support member 5 by different distances in the at least two pivoting positions.

[0095] Preferably, the at least one pivoting component 21:

[0096] - A pivotable rotating shaft 21a is provided about at least one rotating shaft 6a parallel to the at least one adjusting arm 6, and / or

[0097] - Pivotibly supported on at least one adjusting arm 6, and / or

[0098] - Having at least two or more cavities 26a, 26b, 26c, 26d, 26e for partially receiving the stop 22, and / or

[0099] - A tooth portion 21b having at least one preferably non-circular tooth portion.

[0100] The different cavities 26a, 26b, 26c, 26d, and 26e of the pivot component 21 are therefore configured to partially accommodate the stop 22 and to limit the maximum open position of the adjusting arm 6 at a predetermined location.

[0101] The adjusting device 9 further includes an operating component 24, which is kinetically coupled to the at least one pivoting component 21, preferably the at least one operating component 24.

[0102] - Pivotibly supported on at least one adjusting arm 6, and / or

[0103] - Connected to the at least one pivoting member 21 via at least one tooth 24a, 21b in a kinetic coupling, and / or

[0104] - Can be approached directly and indirectly for manual operation, and / or

[0105] -Having at least one operating profile 24b disposed on the circumferential side, particularly preferably provided that the operating profile 24b is at least partially accessible for manual operation via an opening 25 disposed or constructed on the adjusting arm 6, and / or

[0106] -At least one preferred stamping graduation 29 ( Figure 5b ,5d ), used to read the position of the maximum open position of the at least one adjusting arm 6, and / or

[0107] - Having at least one locking element 24d, preferably resiliently constructed or constructed as a spring tongue, by which the operating member 24 can be releasably locked in at least two different positions, and / or

[0108] - A tooth portion 24a having at least one tooth portion preferably configured as a non-circular tooth portion.

[0109] The transmission ratio of the relative motion between the operating component 24 and the pivoting component 21 can be changed by the size and geometry of the teeth 24a and 21b that work together, for example, so that the pivoting component 21 can pivot around the rotation axis 21a by a relatively small operating component 24 without requiring a large amount of manual force.

[0110] The carrier 5 has an end face 17 with at least one opening 17a through which the at least one adjusting arm 6 extends in the open position, wherein the operating component 24 can be operated from a direction transverse to the end face 17 through the opening 17a.

[0111] Preferably, the at least one stop 22:

[0112] - Statically mounted on the at least one support member 5, and / or

[0113] - A pin constructed in a generally cylindrical shape, and / or

[0114] - Having a longitudinal axis extending parallel to the at least one rotation axis 6a of the at least one adjusting arm 6, and / or

[0115] - A stabilizing element constructed for stabilizing two shell walls 5a that extend parallel to each other in order to stabilize the bearing member 5.

[0116] The adjusting arm 6 or the adjusting arm protrusion 6b has at least two spaced-apart recesses 23 for partially accommodating the adjusting arm extension 11. Figure 2a The locking element on (and not shown here).

[0117] In order to mount the adjusting arm extension 11 onto the adjusting arm 6, the following steps can be specified, for example:

[0118] -The adjusting arm extension 11 is hooked into the first recess 23 by the first locking element.

[0119] - In the engaged state, the adjustment arm extension 11 pivots about an axis, preferably wherein the axis extends substantially horizontally when the furniture drive device 4 is mounted on the furniture body 2.

[0120] - The adjusting arm extension 11 and the adjusting arm 6 are separably locked by the force of the second locking element (which is loaded by the accumulator), wherein the second locking element is embedded in the second recess 23 in the connection state between the adjusting arm extension 11 and the adjusting arm 6.

[0121] Figures 4a-4c An adjustment device 9 is shown for adjusting the position of the adjustment arm 6 at its maximum open position, wherein the adjustment arm 6 is located in different maximum open positions.

[0122] exist Figure 4a In this configuration, a fixed stop 22 is located in the cavity 26e of the pivot member 21, thereby positioning the adjusting arm 6 relative to the carrier member 5 at its maximum pivot angle. It can be seen that the adjusting arm 6 or the adjusting arm protrusion 6b has a stop element 27, wherein, during the opening movement of the adjusting arm 6, the damping device 18, preferably a piston-cylinder unit, can be loaded by the stop element 27. In this way, the final opening movement of the adjusting arm 6 can be braked until it reaches the fully open position.

[0123] Figure 4b The intermediate adjustment of the maximum pivot angle of the adjusting arm 6 is shown, wherein the stop 22 is accommodated in the cavity 26d of the pivoting member 21.

[0124] at last, Figure 4c The minimum adjustment of the pivot angle of the adjusting arm 6 is shown, wherein the fixed stop 22 is accommodated in the cavity 26a of the pivoting member 21.

[0125] Figure 5a The adjusting arm 6 is shown in its minimum maximum open position. The adjusting arm 6 is rotatably supported about a rotation axis 6a and has a control curve 13a eccentric relative to the rotation axis 6a. A pressure roller 19 is loaded by a spring device 10. Figure 3a You can scroll on this control curve.

[0126] The adjusting arm 6 is connected to or detachably connected to the adjusting arm protrusion 6b, and the adjusting arm protrusion 6b can be detachably locked to the adjusting arm extension 11 via the notch 23. Figure 2a ).

[0127] Two or more holes 28 are constructed on the adjusting arm 6, and the locking element 24d of the operating component 24 ( Figure 3b The adjustment arm 6 can be releasably locked into these holes 28. In this way, the adjustment arm 6 can be positioned in at least two different maximum open positions predetermined by the holes 28. In the illustrated embodiment, there are five holes 28, through which five different maximum open positions of the adjustment arm 6 can also be adjusted. The number of holes 28 can, of course, vary.

[0128] Figure 5bShown in enlarged diagram Figure 5a The area circled in the center shows the opening 25 on the adjusting arm 6, through which the operating contour 24b of the operating component 24 partially passes. The adjustment of the maximum open position of the adjusting arm 6 can be read by at least one preferably stamped scale 29.

[0129] Figure 5c The adjusting arm 6 is shown in another fully open position. Figure 5d Shown in enlarged diagram Figure 5c The area circled in the middle.

[0130] The adjusting arm 6 can therefore be positioned in two or more maximum open positions via the adjusting device 9. To change the maximum open position, the adjusting arm 6 is moved slightly in the closing direction from the maximum open position, and then the operating member 24 is manually rotated about the rotation axis 24c, preferably to one of the predetermined switching positions 1-5. Then, the adjusting arm 6 is moved in the opening direction again, and the stop member 22 can selectively engage with one of the cavities 26a, 26b, 26c, 26d, 26e of the operating member 24.

[0131] Figure 6a and Figure 6b The furniture drive device 4 is shown according to a slightly modified embodiment, wherein the pivoting component 21 is in two different positions.

[0132] The adjusting arm 6 is pivotally supported on the carrier 5 about a rotation axis 6a, and the maximum open position of the adjusting arm 6 can be limited by the adjusting device 9. The adjusting device 9 includes an operating member 24 rotatable about a rotation axis 24c, the teeth 24a of the operating member 24 engaging with the teeth 21b of the pivoting member 21. The maximum open position of the adjusting arm 6 can be adjusted by manually or with the aid of a tool rotating the operating member 24 to rotate the pivoting member 21 about the rotation axis 21a.

[0133] In the foregoing embodiment, the rotational position of the pivot component 21 is determined by the at least one locking element 24d ( Figure 3b The locking element is selectively accommodated in hole 28. Figure 5a One of them. However, the pivoting component 21 has an undesirable tendency to pivot about the rotation axis 21a, especially when the adjusting arm 6 moves at high speed toward the open position.

[0134] As a replacement or supplement to the at least one locking element 24d, according to Figure 6a , 6b An embodiment may specify that the at least one pivoting member 21 has at least two arcuate abutment contours 30a, 30b, 30c, 30d, 30e, which can abut against the at least one stop member 22.

[0135] The at least two abutting contours 30a, 30b, 30c, 30d, and 30e correspond to arcs of imaginary circles 32a and 32b surrounding the rotation axis 21a of the pivot component 21, respectively, wherein the two imaginary circles 32a and 32b have different radii. The different radii of the two circles 32a and 32b can be directly compared. Figure 6a and Figure 6b It is clearly visible.

[0136] In other words, the contact surfaces between the preferably cylindrical stop 22 and the contact surfaces 30a, 30b, 30c, 30d, and 30e of the pivot component 21 are respectively located on an imaginary connecting line 31, which connects the central axis of the stop 22 and the rotation axis 21a of the pivot component 21.

[0137] In this way, tangential forces are prevented from occurring on the contact contours 30a, 30b, 30c, 30d, and 30e, and therefore no torque is applied to the pivot member 21. The pivot member 21 is thus stably held in a predetermined rotational position on one of the contact surfaces 30a, 30b, 30c, 30d, and 30e.

[0138] In the illustrated embodiment, the pivoting component 21 has five different abutment profiles 30a, 30b, 30c, 30d, and 30e, by which the adjusting arm 6 can be fixed in five different maximum open positions.
