Description

Technical Field

[0001] This invention relates to a furniture drive device for moving movable furniture components, comprising: - Brackets used to secure the furniture to the body. - At least one actuating arm rotatable about at least one first rotation axis, the actuating arm being used to move a movablely supported furniture component relative to the support. - An interface for securing a synchronous shaft, wherein the rotational movement of the at least one actuator arm can be synchronized with the rotational movement of at least one actuator arm of at least one other furniture drive device. - The interface has at least one component that can rotate about a second rotation axis, wherein the second rotation axis is laterally offset relative to the first rotation axis of the actuator arm.

[0002] Furthermore, the present invention relates to an arrangement structure comprising two furniture drive devices of the type to be described, wherein a first furniture drive device is fastened to a first side wall of a furniture body, and a second furniture drive device is fastened to a second side wall of the furniture body opposite to the first side wall, wherein the rotational movement of at least one actuating arm of the first furniture drive device is synchronized with the rotational movement of at least one actuating arm of the second furniture drive device via the synchronization shaft. Background Technology

[0003] WO 2006 / 113953 A1 illustrates a furniture body comprising two furniture drive mechanisms fastened to opposite side walls of the furniture body. Each furniture drive mechanism has a rotatable portion movably coupled to an actuating arm for moving a furniture cover. A synchronizing rod synchronizes the rotational movements of the rotatable portions of the furniture drive mechanisms, allowing the furniture cover to be raised and lowered evenly and without tilting by the two furniture drive mechanisms. The synchronizing rod can also be connected to the rotatable portions when the two furniture drive mechanisms are pre-assembled on the furniture body. A disadvantage of this structure is that the synchronizing rod, in the assembled state, can obstruct the storage of items into and out of the furniture body. Furthermore, the synchronizing rod, being adjacent to the end of the furniture body in the assembled state, can also be visually distracting.

[0004] CN 106639718 A discloses a furniture panel including a cover plate, which is driven relative to the furniture body by two furniture drive devices mounted on the furniture body. Each furniture drive device has a pivotable actuator arm for moving the furniture cover plate. To synchronize the pivoting movements of the two actuator arms, synchronizing rods are provided, which in the assembled state are respectively connected to rotatable synchronizing elements of the furniture drive devices. The rotation axes of the synchronizing rods are laterally offset relative to the rotation axes of the actuator arms. A disadvantage of this structure is that the synchronizing rods in the assembled state significantly hinder the storage of items into or out of the furniture body. Summary of the Invention

[0005] The objective of this invention is to provide a furniture drive device of the type mentioned at the beginning, while avoiding the disadvantages discussed above.

[0006] This is solved according to the present invention by a furniture drive device.

[0007] According to the present invention, the bracket has at least one upper side surface, which faces the top of the furniture body when the furniture drive device is assembled on the furniture body. Compared with the second rotation axis, the first rotation axis has a larger vertical distance from the at least one upper side surface.

[0008] In other words, the first rotation axis of the actuator and the second rotation axis of the rotatable component to be connected to the synchronization axis are set off from each other.

[0009] This approach yields several structural advantages. The rotatable component can be positioned as high as possible within the furniture body while the furniture drive is mounted on the furniture body, and the synchronous shaft coupled to the rotatable component hardly hinders the storage and retrieval of stored items.

[0010] Here, the bracket may be configured such that it has at least one end side, and at least one actuating arm protrudes at least partially from the at least one end side in a position relative to the open position of the movable furniture component, wherein the first rotation axis has a smaller vertical distance from the at least one end side compared to the second rotation axis.

[0011] Furthermore, the rotatable component can be positioned as deep as possible along the depth of the furniture body when the furniture drive device is mounted on the furniture body, and the synchronization shaft coupled to the rotatable component—also due to the shadow cast by the furniture body—is almost invisible visually.

[0012] In one embodiment, at least one coupling device may be provided, through which the rotational movement of the at least one actuator arm can be coupled with the rotational movement of the at least one component of the interface. The coupling device may, for example, have teeth that interact and / or at least one cable drive.

[0013] The at least one coupling device may have at least one tooth, wherein the at least one tooth has at least one tooth sector. Attached Figure Description

[0014] Further details and advantages of the invention will become apparent from the following description of the accompanying drawings.

[0015] Figure 1a , 1b The illustration shows furniture including movable furniture parts and two furniture drive mechanisms for moving the furniture parts, as well as furniture with the furniture parts removed; Figures 2a-2c The synchronous shaft is shown mounted on a rotatable component of a furniture drive unit; Figure 3a , 3b The synchronization shaft is shown in the exploded view and in the assembled state; Figure 4a , 4b Showing a side view of the furniture drive mechanism and a magnified detailed view thereof; Figure 5a , 5b A perspective view of the rotatable components of the interface and an exploded view of the teeth interacting with each other are shown. Figure 6a , 6b The image shows the actuator arm to be connected to the support in both the disengaged and connected states. Detailed Implementation

[0016] Figure 1a The illustration shows a piece of furniture 1 comprising a furniture body 2 and movable furniture parts 3 in the form of a furniture cover 3a that can be raised relative to the furniture body 2. A furniture drive device 4 for moving the movable furniture parts 3 is fastened to each of the opposite side walls of the furniture body 2. Each furniture drive device 4 has a rotatably supported actuator arm 5, wherein the rotational movements of the two actuator arms 5 of the furniture drive device 4 can be synchronized with each other via a synchronizing shaft 6.

[0017] Figure 1b The procedure for removing furniture part 3 is shown. Figure 1a Furniture 1. The two furniture drive mechanisms 4 can be constructed identically, so the explanations listed here are valid for the two furniture drive mechanisms 4 respectively.

[0018] The furniture drive unit 4 has a bracket 9, preferably substantially rectangular hexagonal in shape, to be fastened to the furniture body 2. At least one rod 5a of the actuating arm 5 is pivotally supported on the bracket about a first rotation axis 7a. A synchronizing shaft 6 is rotatably supported about a second rotation axis 7b, wherein the first rotation axis 7a of the rod 5a and the second rotation axis 7b of the synchronizing shaft 6 are laterally offset from each other, and preferably spaced parallel to each other.

[0019] The staggered arrangement between the first rotation axis 7a of the lever 5a of the actuator 5 and the second rotation axis 7b of the synchronizing axis 6 has a particular advantage, namely, the synchronizing axis 6 can be set, for example, at a high position in the furniture body 2, that is, near the top 2a of the furniture body 2.

[0020] Furthermore, compared to the coaxial arrangement between the first rotating shaft 7a and the second rotating shaft 7b known in the prior art, the second rotating shaft 7b can be positioned deeper in the direction of the depth of the furniture body 2 in the assembled state of the furniture drive device 4.

[0021] The lever 5a of the actuator arm 5 has a fitting 8, which can be detachably connected to a fitting body (not shown) to be fastened to the furniture component 3. The fitting 8 can be hinged to the lever 5a of the actuator arm 5 and can be configured such that the fitting 8 can be connected to the fitting body to be fastened to the furniture component 3 without tools.

[0022] Figures 2a-2c The assembly of the synchronous shaft 6 on the furniture drive unit 4 is shown. The actuator arm 5 may have multiple mutually hinged rods 5a, 5b, preferably: - At least two of the rods 5a and 5b of the actuator arm 5 are nested together in at least one rotational position of the actuator arm 5, preferably in each rotational position, such that the two rods 5a and 5b are constructed substantially without gaps between them in a top view viewed from the side, and / or - At least one rod 5b is U-shaped in cross-section and another rod 5a is at least partially provided or may be provided between the vertical segments of the U-shape, and / or - The actuator 5 is constructed symmetrically about an imaginary central plane, and / or - At least one, preferably at least two, of the rods 5a and 5b of the actuator arm 5 can be detachably connected to the bracket 9 of the furniture drive device 4.

[0023] In the illustrated embodiment, the first rod 5a is pivotally supported about a first rotation axis 7a and the other rod 5b is pivotally supported about another rotation axis 10.

[0024] The bracket 9 has at least one upper side surface 31, which faces the top 2a of the furniture body 2 when the furniture drive device 4 is assembled on the furniture body 4, wherein the first rotation axis 7a has a larger vertical distance from the at least one upper side surface 31 compared to the second rotation axis 7b. Figure 1b ).

[0025] The furniture drive device 4 includes an interface 21 for securing a synchronization shaft 6, through which the rotational movement of the at least one actuator arm 5 can be synchronized with the rotational movement of at least one actuator arm 5 of at least one other furniture drive device 4.

[0026] The interface 21 includes a member 11 rotatably supported about a second rotation axis 7b, the member being detachably connected to the synchronization shaft 6. It can be seen that the first rotation axis 7a of the rod 5a and the second rotation axis 7b of the member 11 are spaced parallel to each other.

[0027] The component 11, rotatable about the second rotation axis 7b, has a receiving device 11a for receiving the synchronization shaft 6. Preferably, the receiving device 11a has a non-circular cross-section for receiving the synchronization shaft 6. Particularly preferably, the synchronization shaft 6 is connectable to the receiving device 11a only in a single rotational position within a 360° rotational angular range.

[0028] The synchronous shaft 6 has a journal 6a, the outer contour of which substantially corresponds to the inner contour of the receiving device 11a. In this way, a form-locking connection for transmitting torque between the rotatable component 11 and the synchronous shaft 6 can be established.

[0029] from Figure 2a Starting from this point, the journal 6a of the synchronous shaft 6 is inserted into the receiving device 11a of the rotatable component 11. Figure 2b The cover portion 6b, which is movable along the longitudinal axis (L), is then pushed into the receiving device 11a, wherein the journal 6a is covered. Figure 2c ).

[0030] The first furniture drive device 4 is fastened to the first side wall of the furniture body 2, and the second furniture drive device 4 is fastened to the second side wall of the furniture body 2 opposite to the first side wall.

[0031] In the assembled state, the synchronous shaft 6 is non-rotatably connected to the two rotatable support components 11 of the furniture drive device 4, wherein the rotational movement of the at least one actuating arm 5 of the first furniture drive device 4 and the rotational movement of the at least one actuating arm 5 of the second furniture drive device 4 can be synchronized through the synchronous shaft 6.

[0032] Figure 3aAn exploded view of the synchronization shaft 6 is shown. The synchronization shaft 6 includes an intermediate shaft member 6g, which may have a non-rotationally symmetric cross-section.

[0033] The connector 6f is connectable to the first end region of the shaft 6g, wherein the connector 6f is configured to receive the spring element 6d. The journal 6a is formed on the loadable portion 6c via the spring element 6d, wherein the journal 6a is pressed against the rotatable member 11 by the spring element 6d in the assembled state of the synchronous shaft 6.

[0034] The portion 6c is prevented from disengaging from the connector 6f by the limiting element 6e. At least the journal 6a can be covered by the preferably sleeve-shaped cover portion 6b.

[0035] Preferably, the spring element 6d is absent in the second end region of the synchronous shaft 6. Here, the connector 6h has a form-locking connection for the non-rotatable connection between the synchronous shaft 6 and the rotatable component 11 of the opposing furniture drive device 4, and a movable cover 6i.

[0036] Figure 3b Synchronous shaft 6 is shown in its assembled state.

[0037] Figure 4a A side view of the furniture drive device 4 is shown. The furniture drive device 4 has at least one accumulator 12, preferably supported on a bracket 9, which preferably includes at least one spring element 12a, through which the actuator arm 5 (not shown here) can be force-loaded to compensate for the weight of the furniture component 3 to be fastened to the actuator arm 5.

[0038] The force that can be stored in the accumulator 12 can be transmitted to the actuator 5 via the transmission mechanism 17. Preferably, the transmission mechanism 17 includes...

[0039] - At least one intermediate rod 13 pivotable about a rotation axis 13a, preferably the at least one accumulator 12 is connected to the at least one intermediate rod 13 via a preferably adjustable actuating part 14, and / or

[0040] - At least one pressure member 15, preferably a rotatable pressure roller, and at least one adjustment profile 16, wherein the at least one pressure member 15 is movably supported on the adjustment profile when the actuator arm 5 moves, preferably the at least one pressure member 15 is disposed or may be disposed on at least one intermediate rod 13 of the transmission mechanism 17 and the at least one adjustment profile 16 is disposed or may be disposed on the actuator arm 5, or vice versa.

[0041] The interface 21 has a component 11 rotatable about the rotation axis 7b, the component being provided with a receiving device 11a for detachably receiving the synchronization shaft 6.

[0042] The furniture drive device 4 has at least one coupling device 18 through which the rotational movement of the at least one actuator arm 5 can be coupled with the rotational movement of the at least one component 11 of the interface 21. It can be seen that the rotation axis 7a of the actuator arm 5 and the rotation axis 7b of the rotatable component 11 are staggered from each other.

[0043] According to one embodiment, the at least one coupling device 18 may be configured to have a non-circular transmission mechanism.

[0044] The coupling device 18 may have at least one tooth 19, 20, preferably the at least one tooth 19, 20 having at least one tooth sector 19a, 20a ( Figure 5a , Figure 5b ).

[0045] Figure 4b Shown in Figure 4a An enlarged view of the circled area shows, in which the coupling device 18 for coupling between the actuator arm 5 and the rotatable member 11 is shown in more detail.

[0046] Figure 5a An interface 21 is shown for detachably securing the synchronous shaft 6.

[0047] According to one embodiment, the at least one tooth 19, 20 may have at least two tooth sectors 19a, 20a, wherein...

[0048] - One of the two gear sectors, 19a, is connected to or can be connected to the at least one actuator arm 5, and the other gear sector, 20a, is connected to or can be connected to the interface 21, and / or

[0049] - At least two gear sectors 19a, 20a are arranged in layers abutting each other along the direction of the first or second rotation axis 7a, 7b.

[0050] The at least two toothed sectors 19a, 20a are arranged in layers abutting each other along the direction of the first or second rotation axis 7a, 7b in the figure shown, wherein one of the at least two toothed sectors 19a, 20a is made of a first material, and the other toothed sector 19a, 20a is made of a second material, the second material having a lower hardness than the first material, preferably the first material is steel and / or the second material is plastic.

[0051] According to a preferred embodiment of the present invention, at least two toothed sectors 20a, 20b are arranged in a layered manner abutting each other along the direction of the first or second rotation axis 7a, 7b, wherein one toothed sector of the at least two toothed sectors 20a, 20b extends radially beyond the other toothed sector 20a about the first or second rotation axis 7a, 7b.

[0052] In other words, in Figure 5a In this configuration, at least one intermediate toothed sector 20a, preferably made of elastic plastic, is received between two outer toothed sectors 20a, preferably made of steel, wherein the intermediate toothed sector 20a extends radially beyond the two outer toothed sectors 20a. This reduces the gap between the teeth 19, 20 of the coupling device 18 and significantly improves synchronization between the two rotatable components 11 of the furniture drive device 4.

[0053] Figure 5b An exploded view of the teeth 19 and 20 that interact with each other is shown.

[0054] The teeth 20 are disposed on the rotation axis 7b of the rotatable component 11 and have a plurality of toothed sectors 20a that abut against each other. The toothed sectors 20a are substantially disc-shaped and supported on the rotation axis 7b of the component 11 by spacers 22.

[0055] The other tooth 19 is disposed on the first rotating shaft 7a of the actuator arm 5.

[0056] In one embodiment, the at least one tooth 19 may have at least one toothed sector 19a, wherein at least one preload element 23 is provided, by which the at least one toothed sector 19a can be pressed radially about the first or second rotation axis 7a, 7b, preferably.

[0057] - The at least one preload element 23 may be elastically telescopically constructed or constructed as a mechanical spring element, and / or

[0058] - The at least one preload element 23 is constructed substantially in a ring shape, and / or

[0059] - The at least one preload element 23 is supported on the first or second rotating shaft 7a, 7b, and / or

[0060] - At least one guide device 26 is provided, wherein the at least one toothed sector 19a is movably, preferably linearly, supported along the guide device 26.

[0061] In other words, in Figure 5bIn this configuration, at least one or more intermediate toothed sectors 19a are received between two outer toothed sectors 19a, wherein the intermediate toothed sector 19a is radially outwardly pressed by a preload element 23, such that the intermediate toothed sector 19a extends slightly beyond the two outer toothed sectors 19a in the radial direction. This reduces the gap between the teeth 19, 20 of the coupling device 18 and improves synchronization between the two rotatable components 11 of the two furniture drive devices 4.

[0062] At least one tooth 19a of the outer toothed sector may have a guide 26 for movably supporting the intermediate toothed sector 19a.

[0063] For example, it can be configured such that at least one intermediate toothed sector 19a, 20a extends beyond the two outer toothed sectors 19a, 20a by a distance between 0.01mm and 0.1mm, preferably between 0.03mm and 0.07mm.

[0064] At least one tooth 19, 20 may have a connecting device 27 for detachably connecting the rods 5a, 5b of the actuator 5. The connecting device 27 may, for example, have at least one gap 27a for partially receiving the rods 5a, 5b of the actuator 5.

[0065] By means of the unlocking element 24 pre-tensioned by the spring 25, one of the levers 5a, 5b of the actuator arm 5 can be unlocked from the state of connection with the bracket 9, preferably from the state of connection with the teeth 19, 20. In this way, the actuator arm 5 can be separated from the bracket 9. By actuating the unlocking element 24 with a force opposite to that of the spring 25, the locking between the actuator arm 5 and the teeth 19, 20 can be released.

[0066] Figure 6a The actuator arm 5 is shown as a rod 5a to be connected to the support 9. The toothed portion 19, preferably the tooth sector 19a, has at least one preferably funnel-shaped gap 27a for partially receiving the rod 5a. It can be seen that the contour of the gap 27a is at least partially adapted to the contour of the rod 5a, wherein the rod 5a is form-locked into the gap 27a in the connected state.

[0067] The rod 5a is suspended from a first locking element disposed on a first rotating shaft 7a via a first notch 28a. When the rod 5a is pushed into the gap 27a, the second locking element 29 moves along the guide rail 30 by a force acting in opposition to the spring 25, in conjunction with the rod 5a. A locking element 29a, such as a pin protruding laterally from the rod 5a, is provided on the rod 5a, wherein the locking element 29a is engaged in another gap 29b in the connected state of the rod 5a. The locking of the rod 5a is established by the locking element 29, which can be locked into the second notch 28b of the rod 5a by the force of the spring 25. Figure 6b ).

[0068] A special anti-overturning connection between the rod 5a and the bracket 9 can be established by three-point locking (notch 28a on the rotating shaft 7a, locking element 29a in the gap 27b, and locking element 29 in the notch 28b).

[0069] The gap 27a of the toothed portion 19 can form an inlet funnel for introducing the rod 5a of the actuator arm 5, thereby allowing the rod 5a to be centered along the direction of the rotation axis 7a during assembly.

[0070] In order to release the lock between the rod 5a and the bracket 9, the unlocking element 24 moves against the force of the spring 25 until the second locking element 29 can be unlocked with the second notch 28b of the rod 5a.
