Description

Technical Field

[0001] This invention relates to a furniture drive mechanism for moving furniture components movably supported relative to a furniture body, particularly furniture doors capable of pivoting about a horizontal axis relative to the furniture body. The furniture drive mechanism includes:

[0002] - A housing that can be installed on or within the furniture body.

[0003] - An actuator arm assembly for moving the movable furniture component, wherein the actuator arm assembly has at least one actuator arm movably supported relative to a housing, on which the movable furniture component can be secured, and the actuator arm assembly is movable at least between a first relative position corresponding to a closed position of the movable furniture component and a second relative position corresponding to a fully open position of the movable furniture component.

[0004] - A releasable locking device, wherein the actuator arm assembly has at least two actuator arms that are pivotable relative to each other, and the pivoting movement of the actuator arm assembly can be locked from a second relative position toward a first relative position by the at least one locking device, the releasable locking device having at least one locking element that is movably, preferably pivotally supported, the locking element being movably supported between a locked position and at least one released position, in which the movement of the actuator arm assembly between the first and second relative positions can be released.

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

[0006] WO 2011 / 011800 A2 discloses an adjusting drive mechanism for moving a furniture door, having a pivotally supported actuator arm. The adjusting drive mechanism includes a spring device for applying force to the actuator arm and a locking device, by which the locking device can releasably lock the actuator arm relative to the housing of the adjusting drive mechanism in a pivot position. This locking device prevents dangerous displacement of the actuator arm towards the open position due to the force of the spring device. The locking device is configured such that the locking of the actuator arm is only released after the movable furniture component is properly connected to the actuator arm. In the locked position, the actuator arm is restricted in both directions of movement, optionally with a slight clearance, which may make it difficult to install the movable furniture component onto the actuator arm. Summary of the Invention

[0007] Therefore, the objective of this invention is to provide a furniture drive device of the type described at the beginning, while avoiding the disadvantages discussed above.

[0008] According to the present invention, this is solved by a furniture drive device.

[0009] In other words, according to the present invention, the at least one locking element of the locking device is supported on one of the at least two actuators and has a stop portion that can rest against the matching stop portion of the other actuator of the at least two actuators in the locked position of the at least one locking element and in a locked angle position of the actuator assembly relative to the housing. The actuator assembly is free to move between the second relative position and the locked angle position, and pivoting movement of the actuator assembly beyond the locked angle position from the second relative position toward the first relative position is prevented.

[0010] In other words, in the case of the present invention, the actuator arm assembly is provided to be freely supported between a second relative position (which corresponds to the fully open position of the movable furniture component) and a locking angle position (in which further movement of the actuator arm assembly toward the first relative position, i.e., toward the fully closed position of the furniture component, is prevented by a locking device).

[0011] This approach improves the flexibility of installing movable furniture components because the actuator arm assembly can be variably positioned by the user between a second relative position and a locking angle position, and thus can be brought into a comfortable position for mounting the movable furniture component onto the actuator arm assembly. Consequently, multiple positions of the actuator arm assembly are available to the user, in which the movable furniture component can be connected to the actuator arm.

[0012] According to one embodiment, the at least one locking element of the locking device is preferably pre-tightened towards the release position by a force-accumulating device. In this way, the locking element can be immediately moved to the release position by the force of the force-accumulating device, provided that no force is applied to the locking element.

[0013] According to another embodiment, the releasable locking device may have at least two locking elements that are movably, preferably pivotally supported, the locking elements being movably supported relative to each other between a locked position and at least one released position, wherein pivoting movement of the actuator assembly beyond the locking angle position from a second relative position toward a first relative position is prevented in the locked position of the locking elements and in the locked angle position of the actuator assembly relative to the housing.

[0014] According to another embodiment, the at least two locking elements of the locking device may be abutted against each other in the locked position and / or spaced apart from each other in the released position.

[0015] According to another embodiment, at least one operating device is provided, which is releasably connected to or can be connected to the at least one actuator arm, and the actuator arm assembly can be moved from a first relative position to a second relative position by means of the operating device. Preferably, the at least one locking element or each locking element of the locking device can be moved from a locked position to a released position due to the installation of the operating device or an accessory element that can be connected to a movable furniture part.

[0016] In other words, an operating device, in the form of an opening auxiliary device, can be connected to or detachably connected to the at least one actuator arm, by means of which the at least one actuator arm—in the state of being connected to the operating device—can move from a closed position to an open position, in the closed position where the at least one actuator arm is disposed inside the housing, and in the open position where the at least one actuator arm is disposed outside the housing.

[0017] Therefore, the entire actuator arm assembly of the furniture drive unit can be in a compact first relative position in the delivery state, in which the actuator arm assembly is inside the housing. After the furniture drive unit is installed on the furniture body in its compact delivery state, the user can remove the at least one actuator arm from the housing by means of a control device, in which the user applies manual force (preferably a manual pulling motion) to the control device connected to the actuator arm.

[0018] The operating mechanism is particularly advantageous if the housing of the furniture drive unit is completely housed within the furniture panel of the main body of the furniture in the installed state. Without an operating mechanism, the user might have to attempt to pry at least one actuator arm out of the housing, for example, using a screwdriver. This process can be extremely dangerous, especially if a spring mechanism is provided to apply force to the actuator arm assembly. The actuator arm could then be uncontrollably deflected in the open position due to the force of the spring mechanism, posing a significant risk of personal injury or damage to property. Furthermore, prying the actuator arm out of the housing carries the risk of damage to the actuator arm assembly due to improper tool positioning, particularly scratching.

[0019] According to one embodiment, the at least one operating device can be provided with at least one recess for receiving a tool, preferably a screwdriver. Therefore, the tool, preferably a screwdriver, can be introduced into the recess provided in the operating device, wherein the actuator arm connected to the operating device can be controllably moved from its closed position inside the housing to its open position outside the housing by means of a lever arm extended by the screwdriver. This is particularly advantageous if the actuator arm assembly of the furniture drive device—as mentioned above—is force-loaded by a spring mechanism. In this way, the controllable opening movement of the adjusting assembly is possible by applying a reaction force using the tool.

[0020] According to one embodiment, it can be specified that

[0021] - The actuator assembly is loaded via a spring mechanism in a direction toward a first relative position within a first pivot angle region and in a direction toward a second relative position within a second pivot angle region, and / or

[0022] - The spring device has at least one helical spring, preferably at least one compression spring.

[0023] The furniture according to the invention comprises a furniture body, furniture components movably supported relative to the furniture body, in particular a furniture door capable of pivoting relative to the furniture body about a horizontal axis, and a furniture drive device of the type for moving the movably supported furniture components. According to one embodiment, the housing of the furniture drive device is substantially entirely housed within the furniture panel of the furniture body. Attached Figure Description

[0024] Further details and advantages of the present invention will be described with reference to the following drawings. The drawings are as follows:

[0025] Figure 1a , Figure 1b Furniture with movable furniture parts is shown in perspective and exploded view;

[0029] Figure 5a , Figure 5b A perspective view of the furniture drive mechanism and an enlarged detail view thereof are shown.

[0030] Figure 6a , Figure 6b The control device connected to the actuator arm is shown in side and cross-sectional views;

[0031] Figures 7a to 7d The diagram shows the actuator arm assembly in two different relative positions, along with enlarged details of it. Detailed Implementation

[0032] Figure 1a The diagram shows a perspective view of furniture 1, which has a furniture body 2, furniture components 3 movably supported relative to the furniture body 2, and at least one furniture drive mechanism 4 for moving the movable furniture components 3. Furniture 1 has furniture panels 6 in the form of side walls, an upper bottom 7, and a lower bottom 8. The movable furniture components 3 may, for example, be configured as furniture doors 3a capable of pivoting about a horizontal axis relative to the furniture body 2.

[0033] In the illustrated embodiment, the housing 9 of the furniture drive device 4 is at least partially, preferably substantially completely, built into the sidewall of the furniture panel 6, wherein the movable furniture component 3 is movably supported between a closed position covering the furniture body 2 and an open position raised relative to the furniture body 2.

[0034] Of course, it is also feasible to embed the furniture drive unit 4 in a horizontally extending furniture panel, such as in the upper bottom 7, the lower bottom 8 and / or in the shelf 13 disposed between the upper bottom 7 and the lower bottom 8. Figures 2a to 2d In this case, the movable furniture component 3 is pivotally supported relative to the furniture body 2 about an axis extending vertically in the installation position.

[0035] The furniture drive device 4 has an actuator arm assembly 5 for moving the movable furniture part 3 and at least one spring device 10 for applying force to the actuator arm assembly 5. Figure 1b ).

[0036] Figure 1b The furniture 1 is shown in an exploded view, wherein two, preferably identical, furniture drive mechanisms 4 are provided for moving the movable furniture component 3. Each furniture drive mechanism 4 has a housing 9 to be fixed to the furniture body 2. According to one embodiment, the housing 9 of the furniture drive mechanism 4 is at least partially, preferably substantially completely, accommodated within a recess 11 in the sidewall of the furniture panel 6 in the installed state. In the assembled state, the housing 9 can be finished substantially flush with the end face 6a of the furniture panel 6.

[0037] The notch 11 is configured as a blind hole, for example, in which the housing 9 can slide into the bag-shaped notch 11 of the furniture panel 6 when installed from the front (i.e., from the narrow end side 6a of the furniture panel 6). In the assembled state, the furniture drive device 4 is housed within a predetermined wall thickness of the furniture panel 6.

[0038] At least one spring device 10 is provided in or on the housing 9 for applying force to the actuator arm assembly 5. A cover 12 is provided on the front end region of the housing 9, wherein at least one actuator arm 5a, 5b, 5c, 5d (movably supported by the actuator arm assembly 5) Figure 2d It can be guided through cover 12 in a relative position.

[0039] Figures 2a to 2d The illustration shows a piece of furniture 1 with a main body 2, wherein the housing 9 of the furniture drive unit 4 is substantially entirely housed within the furniture panel 6. In addition to the upper bottom 7 and lower bottom 8, the furniture 1 may also have an additional shelf 13. Here, the actuator arm assembly 5 for moving the movable furniture parts 3 is entirely housed within the housing 9 of the furniture drive unit 4, thus giving the furniture drive unit 4 an extremely compact construction in its delivery state. This reduces the packaging size of the furniture drive unit 4 and protects the actuator arm assembly 5 from damage.

[0040] To enable the actuator arm assembly 5 to move out of the housing 9 of the furniture drive unit 4, an operating device 14 is provided. This operating device 14 can be implemented as a component separate from the actuator arm assembly 5, and it can be connected to at least one actuator arm 5a of the actuator arm assembly 5. Figure 2c , Figure 2d It can be loosely connected.

[0041] The housing 9 of the furniture drive unit 4 has a front opening 17 through which at least one actuating arm 5a can be guided. According to one embodiment, the front opening 17 of the housing 9 can be substantially completely covered by the actuating device 14. This reduces the entry of dirt and dust into the interior of the housing 9.

[0042] The operating device 14 has a recess 15 for receiving a tool 16, preferably a screwdriver 16a. By inserting the screwdriver 16a into the recess 15 and then raising the screwdriver 16a, the operating device 14 (together with the at least one actuating arm 5a) can be moved out of the housing 9 of the furniture drive device 4. Figure 2b , Figure 2c ).

[0043] The actuator assembly 5 is movably supported at least between a first relative position and a second relative position, wherein in the first relative position the at least one actuator arm 5a is disposed inside the housing 9, and in the second relative position the at least one actuator arm 5a is disposed outside the housing 9.

[0044] Typically, the actuator arm assembly 5 is loaded by the spring device 10 in a direction toward a first relative position within a first pivot angle region and in a direction toward a second relative position within a second pivot angle region. This means that the spring device 10 applies a closing force to the at least one actuator arm 5a within a closing region not far from the fully closed position. Therefore, from Figure 2a To start, the force of the spring device 10 must first be overcome to apply manual force so that the actuator arm assembly 5 moves from the first relative position (closed position) toward the second relative position (open position).

[0045] Figure 2c The furniture 1 is shown with the actuator arm assembly 5 in a further opened position. From this relative position, an opening force is applied to the actuator arm assembly 5 by the spring device 10. Thus, the user can prevent the at least one actuator arm 5a from deviating uncontrollably by applying manual force with a screwdriver 16a inserted into the recess 15 to counteract the force of the spring device 10.

[0046] exist Figure 2d In this case, the actuator arm assembly 5 of the furniture drive device 4 is in a fully open state. At this time, the operating device 14 can be separated from the actuator arm 5a and reused, for example.

[0047] Figures 3a to 3d The control device 14 is shown in different views. Figure 3a A perspective view of the control device 14 is shown. Figure 3b The control device 14 is shown in a front view. Figure 3c The control device 14 is shown along the edge of the... Figure 3b The cross-sectional view of plane AA drawn in the middle and Figure 3d A perspective view showing a screwdriver 16a inserted into a recess 15.

[0057] Furthermore, a locking device 24 is provided, by means of which the at least one operating device 14, or alternatively, an accessory element that can be connected to the movable furniture part 3, can be releasably connected to the at least one actuating arm 5a, preferably the at least one locking device 24.

[0058] - Including at least one locking element 26 that is elastic or spring-loaded. Figure 4b ) and at least one recess 24b for receiving a locking element 26, wherein the locking element 26 is disposed on the at least one actuating arm 5a and the recess 24b is disposed on the actuating device 14 or an accessory element, or vice versa, and / or

[0060] - Including at least one locking element 26 that is elastic or spring-loaded. Figure 4b ) and at least one retaining pin 28 spaced apart from the locking element 26 Figure 4b ).

[0061] The accessory element is not explicitly shown in the figures. However, as is known per se, the accessory element is configured to be secured to the movable furniture part 3 and is generally configured to be releasably connected to, and in particular, locked without tools, with the at least one actuating arm 5a of the actuating arm assembly 5.

[0062] Figure 4a The diagram shows the actuator arm 5a, pivotally supported around the hinge axis 25, of the actuator arm assembly 5 in a state connected to the control device 14. The control device 14 can be releasably locked to the actuator arm 5a via the locking device 24.

[0063] Figure 4b Showing according to Figure 4a A cross-sectional view of the components, in which the locking device 24 is shown in detail. To install the operating device 14, the retaining pin 28 of the actuating arm 5a is first inserted into the groove 24a of the operating device 14. The operating device 14 is pivoted in the engaged state and then releasably locked by the movably supported locking element 26. The locking element 26, located on the actuating arm 5a, is pre-tensioned towards the locked position by a storage device 27, such as a leaf spring. In the locked state, the locking element 26 of the actuating arm 5a is engaged in the recess 24b of the operating device 14.

[0064] The at least one actuating arm 5a has at least one mounting member 39 on which the movable furniture component 3 can be fixed, and at least one adjusting device 38a, 38b, 38c by means of which the position of the at least one mounting member 39 relative to the at least one actuating arm 5a can be adjusted. In the illustrated embodiment, the at least one actuating arm 5a includes three adjusting devices 38a, 38b, 38c having three rotatably supported operating elements. By means of the adjusting devices 38a, 38b, 38c, the position of the furniture component 3 relative to the actuating arm 4a can be adjusted in three dimensions relative to the actuating arm 5a in the assembled state of the furniture component 3.

[0065] The position of the operating device 14 (or, alternatively, the position of the accessory element to be fixed on the movable furniture part 3) can be adjusted in the lateral direction relative to the actuating arm 5a via the first adjusting device 38a. The tilt of the mounting member 39 relative to the actuating arm 5a can be adjusted via the second adjusting device 38b. The height of the mounting member 39 relative to the actuating arm 5a can be adjusted via the third adjusting device 38c.

[0066] Figure 5a The furniture drive mechanism 4 is shown in perspective. The housing 9 of the furniture drive mechanism 4 has generally flat and parallel-spaced housing walls 9a and 9b. Between the two housing walls 9a and 9b, the actuator arm assembly 5 is fully accommodated within the housing 9 in its first relative position. A spring device 10 for applying force to the actuator arm assembly 5 can also be seen. The spring device 10 can, for example, include a spring assembly having multiple parallel helical springs, preferably compression springs.

[0067] At least one recess 29 is provided on the housing 9, the recess being configured to receive the locking element 23 of the operating device 14. Figure 3a This prevents undesirable opening movements of the actuator arm assembly 5. This is particularly advantageous if the spring device does not apply a closing force to the at least one actuator arm 5a within the closing region, but instead applies a torque acting in the opening direction to the at least one actuator arm 5a within the closing region.

[0068] According to a preferred embodiment, the operating device 14 has at least two mutually separate locking elements 23. The first locking element of the operating device 14 can be received in a first recess 29 of the first housing wall 9a. The second locking element 23 of the operating device 14 can be received in a second recess 29 of the second housing wall 9b. In this way, the operating device 14 can be locked non-tiltingly relative to the housing 9.

[0069] Figure 5b Shown in a magnified view Figure 5a The area circled in the center. The locking element 23 can be at least partially constructed as a cylinder and is received in a circular recess 29 of the housing 9. The lock between the locking element 23 and the recess 29 can be released by a manual pulling motion of the operating element 14, thereby allowing the locking element 23 to move out of the recess 29 against its elastic force. The at least one locking element 23 is movably supported relative to the plane formed by the housing walls 9a, 9b in a substantially vertically extending direction.

[0070] In addition, Figure 5bAs can be seen, a cover 12 is provided on the housing 9 of the furniture drive device 4, the cover having at least one flange 12a that projects laterally and has a generally annular structure. This flange 12a forms a reliably positioned end face 6a of the furniture panel 6. Figure 1b The flange 12a is a depth stop for the housing 9 of the furniture drive device 4, which is located on the furniture drive device 4, so that the housing 9 is in a depth position defined relative to the furniture board 6 in the assembled state. Furthermore, the flange 12a can cover the area between the housing 9 and the recess 11 in the assembled state of the furniture drive device 4. Figure 1b The gap between the inner walls of the ).

[0071] Figure 6a A portion of the actuator arm assembly 5 is shown, wherein at least one actuator arm 5a is hingedly connected to actuator arm 5b via hinge shaft 30 and hingedly connected to actuator arm 5c via another hinge shaft 25.

[0072] The furniture drive device 4 has a releasable locking device 31, wherein the pivoting movement of the actuator arm assembly 5 can be locked from a second relative position toward a first relative position by the at least one locking device 31.

[0073] The releasable locking device 31 includes at least two locking elements 31a and 31b that are movably supported, preferably pivotally supported about rotation axes 32a and 32b, respectively, the locking elements being movably supported relative to each other between a locked position and at least one released position. In the locked position of the locking elements 31a and 31b, movement of the actuator arm assembly 5 between a first relative position and a second relative position can be locked. In the released position of the locking elements 31a and 31b, movement of the actuator arm assembly 5 between the first relative position and the second relative position can be released. The at least two locking elements 31a and 31b of the locking device 31 are abutted against each other in the locked position and / or spaced apart from each other in the released position. At least one locking element 31a and 31b, preferably two locking elements 31a and 31b, can be configured as a double-arm lever with two lever ends.

[0074] The at least one actuating arm 5a has at least one mounting member 39 on which the movable furniture part 3 can be fixed, and has at least one adjusting device 38a, 38b by means of which the position of the at least one mounting member 39 relative to the at least one actuating arm 5a can be adjusted, wherein at least one locking element 31a of the locking device 31 is movably, preferably pivotally supported on the at least one mounting member 39.

[0075] In the attached diagram Figure 6a , 6bIn this configuration, locking elements 31a and 31b are in the released position, allowing movement of the actuator arm assembly 5 between the first and second relative positions. The released position exists because the actuating device 14 is connected to the at least one actuator arm 5a as intended. This is identifiable because the retaining pin 28 of the actuator arm 5a is engaged in the groove 24a of the actuating device 14.

[0076] The first locking element 31a is pivotally supported about the first rotation axis 32a, wherein the first locking element 31a is pre-tightened counterclockwise about the first rotation axis 32a by means of the (not visible here) power storage device 33 and thus abuts against the operating device 14 by means of the force of the power storage device 33.

[0077] The second locking element 31b is pivotally supported about the second rotation axis 32b, wherein the second locking element 31b is pre-tightened in a clockwise direction about the rotation axis 32b due to the power storage device 33 shown, and thus abuts against the support element 35 of the actuator arm 5a due to the force of the power storage device 33.

[0078] With the operating device 14 and the at least one actuator 5a connected as specified, the two locking elements 31a and 31b are spaced apart, thereby releasing movement of the actuator assembly 5 between a first relative position and a second relative position. In the released position, the locking elements 31a and 31b are spaced apart in all relative positions of the actuator assembly 5, which allows for movement between the first and second relative positions. Figure 6a , Figure 6b This can be learned from the text.

[0079] on the contrary, Figure 7a The diagram shows a separated state between the operating device 14 and the at least one actuating arm 5a, whereby the releasable locking device 31 is in a locked position. In the locked position, movement of the actuating arm assembly 5 between a first relative position and a second relative position can be locked or at least restricted. The separated state between the operating device 14 and the actuating arm 5a can be identified if the retaining pin 28 of the actuating arm 5a is no longer engaged in the groove 24a of the operating device 14.

[0080] In the example shown Figure 7a In this configuration, the actuator arm assembly 5 is in a fully open state relative to the housing 9 of the furniture drive device 4. The maximum open position of the actuator arm assembly 5 relative to the housing 9 can be adjusted using an adjustment device known in the prior art. In this way, the flexibility of mounting movable furniture parts 3 onto the at least one actuator arm 5a is improved, because the actuator arm assembly 5 can be moved to a position comfortable for the user due to the variable adjustment of the maximum open position.

[0081] The releasable locking device 31 is configured to prevent the spring device 10 from tensioning due to the movement of the actuator arm assembly 5 from the second relative position (open position) to the first relative position (closed position) as long as the movable furniture part 3 is not connected to the actuator arm 5a. As long as the movable furniture part 3 is not connected to the actuator arm 5a, no counterweight will act on the spring device 10. Therefore, it is possible that the actuator arm 5a and the unconnected furniture part 3 may uncontrollably shift towards the open position. That is, the releasable locking device 31 can lock the movement of the actuator arm assembly 5 from the open position towards the closed position and thus prevent the spring device 10 from tensioning.

[0082] As from Figure 7a As such, since there is no operating device 14, the first locking element 31a is pivoted clockwise about the first rotation axis 32a by the force of the (not shown) power storage device 33. Here, the longer lever arm of the first locking element 31a collidees with the second locking element 31b, thereby causing the second locking element 31b to pivot counterclockwise about the second rotation axis 32b.

[0083] The power storage device 33 used to load the first locking element 31a is constructed more robustly than the power storage device 33 used to load the second locking element 31b, so that the first locking element 31a enables the second locking element 31b to reliably move around the second rotation axis 32b.

[0084] Figure 7b Shown in a magnified view Figure 7a The area circled in the middle. It can be seen that the second locking element 31b has a stop 36, which can collide with the mating stop 37 of the actuator arm 5c.

[0085] Figure 7c This illustrates a further pivoting movement of the actuator arm assembly 5, during which the stop 36 of the second locking element 31b collidees with the mating stop 37 of the actuator arm 5c, thus preventing further pivoting movement of the actuator arm assembly 5 toward the first relative position (closed position). In other words, in the locked position of the locking device 31, the actuator arm assembly 5 can only be moved from its initial position... Figure 7a The position shown in the figure moves to the position in Figure 7c In the position shown, the spring device 10 is prevented from being further tensioned for safety reasons.

[0086] When the operating device 14 or the movable furniture component 3 is mounted on the actuator arm 5a, the releasable locking device 31 is automatically switched back to the released state. Figure 7aBy mounting the operating device 14 or the movable furniture part 3 onto the actuating arm 5a, the first locking element 31a is moved clockwise again around the first rotation axis 32a. This causes the longer lever arm of the first locking element 31a to be spaced apart from the second locking element 31b again. Consequently, the second locking element 31b tilts counterclockwise due to the force of the accumulating device, and the stop 36 is spaced apart from the mating stop 37. In this way, the locking position can be released again. Preferred embodiment:

[0087] - At least one of the at least two locking elements 31a and 31b of the locking device 31 is pre-tightened by the energy storage device 33. Preferably, two of the at least two locking elements 31a and 31b of the locking device 31 are pre-tightened. Particularly preferably, the at least two locking elements 31a and 31b of the locking device 31 are pre-tightened by the energy storage device 33 in different directions of movement and / or each energy storage device 33 has a different spring force. Preferably, at least one energy storage device 33, preferably two energy storage devices 33, has a torsion spring, and / or

[0088] - The at least two locking elements 31a, 31b of the locking device 31 are disposed on the same actuator 5a of the at least two actuator arms 5a, 5b, 5c of the actuator arm assembly 5, and / or

[0089] - One of the at least two locking elements 31a, 31b of the locking device 31 has a support profile 34 in which the support element 35 of the actuating arm 5a can be supported, and / or

[0090] - One of the at least two locking elements 31a, 31b of the locking device 31 is supported on one of the at least two actuator arms 5a, 5b, 5c and has a stop portion 36, which can rest against a mating stop portion 37 on the other actuator arm acting on the at least two actuator arms 5a, 5b, 5c in the locked position, and / or

[0091] - One of the at least two locking elements 31a, 31b of the locking device 31 can be moved from the locked position to the released position due to the installation of the operating device 14 or an accessory element that can be connected to the movable furniture part 3.
