Description

Technical Field

[0001] This invention relates to a furniture drive device for movably supporting furniture components relative to a furniture body, the furniture drive device comprising:

[0002] At least one base for fixing to and / or within the furniture body,

[0003] At least one adjustable arm for fixing to a movable furniture component.

[0004] At least one locking device for locking the at least one adjusting arm onto the at least one base, wherein the at least one locking device includes at least one locking element movable between a locked position and a disengaged position, in which the at least one adjusting arm is locked to the at least one base, and in the disengaged position, the at least one adjusting arm is detachable from the at least one base.

[0005] At least one preferably tool-operable operating device, through which the at least one locking element can be moved from a locked position to a dismounted position.

[0006] Furthermore, the present invention relates to a type of furniture having a furniture body, furniture components movably supported relative to the furniture body, and at least one furniture drive device of the type to be described. Background Technology

[0007] For example, WO2006 / 053352A1 shows a furniture drive device having a base and an adjusting arm removably fixed to the base. The separate construction of the base and the adjusting arm has a particular advantage: the structural dimensions of the furniture drive device are divided into two structural components, and different types of bases with different types of adjusting arms can be combined with each other.

[0008] A known drawback of the structure is that, when the lock between the base and the adjusting arm is released, there is a danger that the user may be caught off guard by the sudden release of the weight of the furniture component connected to the adjusting arm, and the adjusting arm can no longer be held in place by the furniture component fixed to it. This could lead to the sudden fall and damage of the furniture component, injury to the assembler, and damage to the object. Summary of the Invention

[0009] 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, wherein, in particular, user safety should be improved.

[0010] According to the present invention, the furniture drive device has at least one releasable safety device that prevents the at least one locking element from moving from the locked position to the dismounted position when the drive device is operated.

[0011] In other words, a releasable locking device is provided, which prevents the locking from disengaging even when the operating mechanism is manipulated, for example, with the aid of a tool to move the locking element to the disengaged position. Therefore, at least one additional action by the user is required to achieve successful separation between the base and the adjusting arm.

[0012] The additional action could be, for example, an additional relative movement of the adjusting arm relative to the base, particularly a lifting movement. The locking element can only be moved to the disengaged position by the additional relative movement of the adjusting arm initiated by the user (preferably in the opening direction).

[0013] According to one embodiment, the releasable locking device may include at least one abutment profile that is abutting against the at least one locking element under the influence of gravity acting on the at least one adjusting arm and optionally abutting against the at least one locking element by the gravity of the furniture component to be secured to the at least one adjusting arm.

[0014] According to possible embodiments, it can be specified that:

[0015] The at least one contact contour can be lifted off the at least one locking element by the movement of the at least one adjusting arm, overcoming gravity, and / or

[0016] The at least one contact profile includes at least one recess, and the at least one locking element can be arranged at least partially in the recess, and / or

[0017] The at least one adjusting arm has a first end and a second end, the movable furniture component can be fixed on the first end, and the at least one abutment contour is arranged on the second end. Attached Figure Description

[0028] Figure 1a The furniture 1 is shown, which has a furniture body 2 and furniture parts 3 that are movably supported in the form of a furniture flap 3a that can be raised relative to the furniture body 2. The movable furniture parts 3 may be constructed as a single piece or alternatively may also include two or more movable furniture parts 3.

[0029] A furniture drive device 4 for moving movable furniture parts 3 is fixed on each of the opposite side walls of the furniture body 2. Each furniture drive device 4 has at least one rotatably supported adjusting arm 5, wherein the rotational movement of the two adjusting arms 5 can be synchronized with each other by a rotatable synchronous shaft 6.

[0030] Figure 1b Showing according to Figure 1a Furniture 1, wherein furniture component 3 is removed. The two furniture drive devices 4 can be constructed identically, such that the description herein applies to both furniture drive devices 4.

[0031] The furniture drive unit 4 has a base 9, preferably substantially square, to be fixed to the furniture body 2, on which the lever 5a of the adjusting arm 5 is pivotally supported about the rotation axis 7a.

[0032] The synchronizing shaft 6 is rotatably supported around another rotating shaft 7c, wherein the rotating shaft 7a of the lever 5a and the other rotating shaft 7c of the synchronizing shaft 6 are laterally offset from each other, and preferably spaced parallel to each other.

[0033] The staggered arrangement between the rotation axis 7a of lever 5a and the other rotation axis 7c of synchronous axis 6 has the following particular advantage: synchronous axis 6 can be arranged at a higher position in the furniture body 2, that is, it can be arranged close to the bottom 2a of the furniture body 2, and thus provides increased storage space in the furniture body 2.

[0034] Furthermore, it can be specified that, compared to the case where the arrangement is coaxial between the rotation axis 7a and the other rotation axis 7c, the other rotation axis 7c can be arranged deeper in the depth direction of the furniture body 2 when the furniture drive device 4 is installed.

[0035] The adjusting arm 5 may have a fitting 8 that can be detachably connected to a fitting body (not shown) to be fixed to the furniture component 3. The fitting 8 can be hinged to the lever 5a of the adjusting arm 5 and can be configured such that the fitting 8 can be connected to the fitting body to be fixed to the furniture component 3 without tools.

[0036] Figure 2a A furniture drive device 4 is shown for moving movable furniture parts 3, wherein the adjusting arm 5 and the base 9 are separate from each other.

[0037] The base 9 of the furniture drive device 4 has two parallel and spaced-apart shell walls 9a and 9b, each shell wall having a flat, abutting surface for abutting against the furniture body 2. In this way, the base 9 of the furniture drive device 4 can be mounted on a first side wall of the furniture body 2 or alternatively on a second side wall of the furniture body 2 opposite to the first side wall.

[0038] An end-side opening 9c is formed between the two housing walls 9a and 9b of the furniture drive device 4, through which the adjusting arm 5 protrudes at least partially in its maximum open position.

[0039] The adjusting arm 5 is rotatably supported on the base 9 about at least one rotation axis 7a in the installed state.

[0040] In the illustrated embodiment, the adjusting arm 5 includes a plurality of levers 5a, 5b, 5c that are hinged to each other, wherein at least two of the levers 5a and 5b of the adjusting arm 5 are detachably connected to the base 9 of the furniture drive device 4.

[0041] The adjusting arm 5 can move between a closed position and a maximum open position, wherein the adjusting arm 5 is at least partially arranged within the base 9 of the furniture drive device 4 in the closed position.

[0042] The levers 5a, 5b, and 5c of the adjusting arm 5 can form a four-rotation-point geometry, wherein one of the four rotation points of the four rotation-point geometry corresponds to the at least one first rotation axis 7a of the adjusting arm 5.

[0043] In the illustrated embodiment, the adjusting arm 5 is rotatably supported on the base 9 about at least one second rotation axis 7b, wherein,

[0044] —The base 9 of the furniture drive device 4 has an end opening 9c, through which the adjusting arm 5 passes at least partially in its maximum open position, wherein the second rotating shaft 7b has a smaller normal distance to the end opening 9c than the first rotating shaft 7a, and / or

[0045] —The base 9 of the furniture drive device 4 has an upper side 34, which faces the upper bottom 2a of the furniture body 2 when the furniture drive device 4 is fixed to the furniture body 2. Figure 1a , Figure 1b ), wherein the second rotation axis 7b has a smaller normal distance to the upper side 34 than the second rotation axis 7b.

[0046] According to one embodiment, the second rotation axis 7b corresponds to the rotation point of the four-rotation point geometry of the levers 5a, 5b, and 5c of the adjusting arm 5.

[0047] In addition, it can be stipulated that:

[0048] —At least two of the levers 5a and 5b of the adjusting arm 5 are arranged nested together in at least one rotational position of the adjusting arm 5, preferably in each rotational position, such that the two levers 5a and 5b are constructed substantially without gaps between them in a top side view, and / or

[0049] —At least one lever 5a, 5c is constructed in a U-shape in cross-section, and another lever 5b is at least partially arranged or positioned between the vertical plates of the U-shape.

[0050] A fixing interface 35 is constructed on the third lever 5c, through which the movable furniture part 3 can preferably be detachably fixed to the adjusting arm 5, wherein the first lever 5a and the second lever 5b are hingedly connected to the third lever 5c. The third lever 5c is constructed in a bent manner, wherein the two parts 36a and 36b of the bent third lever 5c form an angle of approximately 90° relative to each other.

[0051] Figure 2b Another perspective view shows the furniture drive unit 4, in which the housing wall 9a is concealed.

[0052] The furniture drive mechanism 4 has at least one accumulator 12 preferably supported on the base 9, which preferably has at least one spring element 12a through which force can be applied to the adjusting arm 5. In this way, the weight of the furniture front 3, which can be fixed to the adjusting arm 5, can be compensated.

[0053] exist Figure 2b The accumulator 12 is shown only schematically, and in addition to mechanical spring elements (especially helical springs), the accumulator 12 may also include, for example, pneumatic springs. As an alternative to or supplement to the accumulator 12, an electric drive device for driving the adjusting arm 5 may also be provided.

[0054] According to one embodiment, a transmission mechanism 17 is provided, which can transmit force that can be stored in at least one accumulator 12 to the adjusting arm 5. Preferably, the transmission mechanism 17...

[0055] —Including at least one intermediate lever 13 pivotable about a rotation axis 13a, preferably, the at least one accumulator 12 is connected to the at least one intermediate lever 13 via a preferably adjustable actuating part 14, and / or

[0056] —Including 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 adjustment arm 5 moves. Preferably, the at least one pressure member 15 is arranged or may be arranged on at least one intermediate lever 13 of the transmission mechanism 17 and the at least one adjustment profile 16 is arranged or may be arranged on the adjustment arm 5, or vice versa.

[0057] In the illustrated embodiment, the adjusting arm 5 can be detachably connected to the base 9 of the furniture drive device 4 via two separate locking devices 37, 38. At least one of the two locking devices 37, 38 may have at least one hanging or pushable fixing part 37a, 38a on the base 9 and / or at least one spring 25 ( Figure 5a ) The locking element 37b is loaded.

[0058] The preferred hook-shaped first fixing part 37a of the lever 5b can be suspended on the base 9, for example, on a bolt arranged on the second rotating shaft 7b, wherein the lever 5b can be loosely locked by a spring-loaded locking element 37b.

[0059] The second fixing member 38a of the other locking device 38 can be releasably locked with the movable adjusting member 22, preferably rotatable about the first rotation axis 7a. Preferably, the adjusting profile 16 is constructed on the movable adjusting member 22.

[0060] Figure 3a The assembly of the adjusting arm 5 on the base 9 in the first step is shown, wherein the fixing part 37a of the locking device 37 of the adjusting arm 5 is suspended on a bolt arranged at the second rotating shaft 7b.

[0061] The locking element 37b can be seen, which is linearly movably supported, for example, along at least one guide and preloaded by a spring 25 toward the locked position. The spring 25 can be, for example, a mechanical spring element or a non-elastic component. The locking element 37b has a ramp, through which it can be pushed out against the force of the spring 25 when engaging with the hinge shaft 7b.

[0062] Figure 3b A locking element 37b is shown, which is locked to the rotating shaft 7b. From Figure 3a Upon starting, locking element 37b moves against the force of spring 25 via its inclined plane and is then placed in the locked position with rotation shaft 7b by the force of the relaxed spring 25. Lever 5b is now pivotally connected to rotation shaft 7b.

[0063] Figures 4a to 4c The assembly of adjusting arm 5 onto base 9 is shown in a further step. From according to Figure 3b Starting from the position, levers 5a and 5b pivot about the rotation axis 7b relative to the base 9. Figure 4a The fixing part 38a of the locking device 38 can be supported on the guide element 39 arranged on the adjusting part 22, wherein the laterally extending locking element 38b of the lever 5a can be introduced into the gap 27a of the adjusting part 22.

[0064] exist Figure 4b As can be seen, the movable locking element 38c moves along the guide portion 30 by overcoming the force of the spring 25 (not shown here) through the fixing part 38a of the lever 5a.

[0065] exist Figure 4cAs can be seen, the locking element 38c can enter the locking cavity of the fixing member 38a through the contour formed by the fixing member 38a and by the force of the loaded spring 25, thereby the lever 5a can be loosely locked to the base 9.

[0066] Figure 5a The furniture drive unit 4 is shown in perspective, wherein the adjusting arm 5 is connected to the base 9 of the furniture drive unit 4 via at least one locking device 38.

[0067] The at least one locking device 38 has a locking element 38c that is movable between a locked position and a dismounted position. In the locked position, the at least one adjusting arm 5 is locked to the at least one base 9, and in the dismounted position, the at least one adjusting arm 5 is detachable from the at least one base 9.

[0068] The furniture drive unit 4 may have a force adjustment device 18, through which the force of the accumulator 12 on the at least one adjusting arm 5 is adjustable. Preferably, the force adjustment device 18...

[0069] —Having at least one rotatably supported adjusting wheel 18a, wherein the force of the accumulator 12 acting on the at least one adjusting arm 5 can be adjusted by the rotation of the adjusting wheel 18a, and / or

[0070] —Having at least one lead screw 18b ( Figure 3a , Figure 3b When the force adjustment device 18 is operated, the actuating part 14 of the accumulator 12 can move along the lead screw, and / or

[0071] —The substrate 9 has an end side with at least one end side opening 9c ( Figure 2a The at least one adjusting arm 5 protrudes through the end-side opening in the open position, wherein the adjusting wheel 18a of the force adjusting device 18 can be manipulated through the end-side opening 9c from a direction transverse to the end side.

[0072] Figure 5b As shown, the furniture drive unit 4 further includes at least one operating device 11, preferably operable with the aid of a tool 10, through which the at least one locking element 38c can be moved from a locked position to a disassembled position. In the disassembled position, the adjusting arm 5 can be detached from the base 9.

[0073] The operating device 11 may have an opening 11a for introducing the tool 10, wherein the locking element 38c can be moved to the disassembly position by force applied to the locking element 38c overcoming elastic action.

[0074] Therefore, two different possibilities arise for the user when introducing tool 10. On the one hand, the rotatable adjusting wheel 18a of the force adjustment device 18 can be manipulated; on the other hand, the locking between the adjusting arm 5 and the base 9 can be released via the operating device 11. Thus, if the user does not unintentionally manipulate the operating device 11 instead of the force adjustment device 18, the locking between the base 9 and the adjusting arm 5 may also unintentionally release. As a result, the adjusting arm 5, along with the movable furniture part 3, falls.

[0075] Figure 6a The furniture drive mechanism 4 is shown in a side view, wherein the user attempts to insert tool 10 into the opening 11a of the operating device 11. Figure 5a , Figure 5b The locking element 38c of the locking device 38 is used to overcome the force of the spring 25. Figure 6b ).

[0076] Figure 6b Shown in magnified view according to Figure 6a The area of ​​the locking element 38c. It can be seen that the fixed part 38a of the adjusting arm 5 is accommodated between the stationary guide element 39 (preferably in the form of a cylindrical bolt) and the movable guide element 38c of the locking device 38.

[0077] In addition to the locking device 38, the furniture drive device 4 also has a releasable safety device 19 that prevents the at least one locking element 38c from moving from the locked position to the dismounted position when the operating device 11 is operated.

[0078] The releasable locking device 19 may include at least one abutment profile 19a, which is able to abut against the at least one locking element 38c under the influence of gravity acting on the at least one adjusting arm 5 and, if necessary, abut against the at least one locking element 38c by the gravity of the furniture component 3 to be fixed to the at least one adjusting arm 5.

[0079] According to one embodiment, it can be specified that:

[0080] —The at least one contact profile 19a can be lifted off the at least one locking element 38c by the movement of the at least one adjusting arm 5, overcoming gravity, and / or

[0081] —The at least one contact contour 19a includes at least one cavity 19c, and the at least one locking element 38c can be arranged at least partially in the cavity, and / or

[0082] —The at least one adjusting arm 5 has a first end and a second end, the movable furniture part 3 can be fixed on the first end, and the at least one abutment profile 19a is arranged on the second end.

[0083] In the illustrated embodiment, the guide portion 30 for movably supporting the locking element 38c, together with the fixing member 38a of the adjusting arm 5, forms a common abutment profile 19a for the locking element 38c.

[0084] Therefore, if an attempt is made to push the locking element 38c out of the locked position by applying force with the aid of tool 10, movement of the locking element 38c in the direction of the disassembly position is prevented. The locking element 38c is locked between the cavity 19c and the fixing part 38a of the adjusting arm 5 and cannot continue to move along the guide 30 to the disassembly position. Therefore, the locking between the base 9 and the adjusting arm 5 is maintained even though the operating device 11 is operated by the releasable locking device 19.

[0085] Figure 7a The furniture drive mechanism 4 is shown in a side view. To release the lock, the adjusting arm 5 must first be moved in the opening direction OR (i.e., in the direction of the drawn arrow).

[0086] Figure 7b Shown in magnified view according to Figure 7a The locking element 38c is located in the area of ​​the adjusting arm 5. By moving the adjusting arm 5 in the opening direction OR, the fixing part 38a of the adjusting arm 5 tilts counterclockwise around the guide element 39, thereby releasing the locking element 38c from the recess 19c abutting the contour 19a. It is now possible for the locking element 38c to move along the guide portion 30 to the disassembly position, allowing the adjusting arm 5 to be disassembled from the base 9 of the furniture drive unit 4.

[0087] According to possible embodiments, the guide section 30 may be specified.

[0088] —At least partially constituted as an elongated aperture, and / or

[0089] —Arranged on the base 9, preferably on the rotatable adjustment component 22 of the base 9, and / or

[0090] —Including at least one cavity 19c, wherein the at least one locking element 38c can be arranged at least partially in the cavity.

[0091] In another embodiment, the control device 11 may be specified.

[0092] —It can be manipulated in the open position of the at least one adjusting arm 5, and / or

[0093] —Arranged on the end side of the furniture drive unit 4 facing the user in the installation position of the furniture drive unit 4, and / or

[0094] —Having at least one opening 11a for introducing the tool 10, wherein the at least one locking element 38c can be manipulated by means of the tool 10 introduced through the opening 11a.

[0095] In another embodiment, it may be specified that:

[0096] —The at least one locking device 38 has at least one fixing member 38a arranged on the adjusting arm 5, the fixing member being suspendable and / or pushable into the base 9 of the furniture drive device 4, and / or

[0097] —The at least one locking device 38 has at least one fixing member 38a arranged on the adjusting arm 5, the fixing member being received between the locking element 38c and the guide element 39 of the furniture drive device 4 in the locked position of the adjusting arm 5, and / or

[0098] —The at least one locking device 38 has at least one spring 25 by which the at least one locking element 38c can be pressed toward the locking position, and / or

[0099] —The at least one locking element 38c of the at least one locking device 38 is configured as a bolt, preferably a cylindrical bolt.

[0100] Figure 8a A side view of the furniture drive unit 4 is shown, which has a slightly modified safety device 19.

[0101] Figure 8b Showing according to Figure 8a The area of ​​the locking element 38c, wherein the cavity 19c, in order to partially receive the locking element 38c, is not arranged on the guide portion 30 as in the above embodiment, but is arranged on the adjusting arm 5. However, the operating principle of the safety device 19 is essentially the same.

[0102] In the locked state of the adjusting arm 5, the locking element 38c is received between the fixing member 38a and the guide portion 30 of the adjusting arm 5. Because the locking element 38c is locked between the cavity 19c of the fixing member 38a and the guide portion 30, the movement of the locking element 38c into the disassembly position is prevented.

[0103] Figure 9a Showing according to Figure 8a , Figure 8b In one embodiment of the furniture drive device 4, the lock between the base 9 and the adjusting arm 5 can only be released by additionally lifting the adjusting arm 5 in the opening direction OR.

[0104] Figure 9b Showing according to Figure 9a The area of ​​the locking element 38c. By lifting the adjusting arm 5 in the opening direction OR, the fixing part 38a is tilted counterclockwise around the guide element 39, preferably in the form of a cylindrical bolt.

[0105] By tilting the fixing member 38a around the axis formed by the guide element 39, the path for locking element 38c to the disassembly position along the guide 30 is released. Now, locking element 38c can move to the disassembly position by overcoming the force of spring 25 by the force applied by tool 10, so that adjusting arm 5 can be disassembled from base 9.

[0106] Therefore, the adjusting arm 5 can only be detached from the base 9 when the first movable furniture part 3 moves further in the opening direction OR while in the open state and then the operating device 9 is operated to release the lock. This is a significant safety aspect, as the user must firmly grip the adjusting arm 5 and / or the furniture part 3 connected to the adjusting arm, thereby preventing the movable furniture part 3 from falling.
