Furniture drive for moving a furniture part that is movable relative to a furniture body

Description

[0001] The present invention relates to a furniture drive for moving a furniture part that is mounted to be movable relative to a furniture body, comprising: an adjusting device with at least one rotatably mounted adjusting element, a transmission mechanism for transmitting a force from the adjusting element, at least one overload protection device which, when the adjusting element is rotated with a torque below a predetermined limit torque, couples the adjusting element to the transmission mechanism and, when the adjusting element is rotated with a torque above the limit torque, decouples the adjusting element from the transmission mechanism, preferably so that no torque transmission takes place between the adjusting element and the transmission mechanism.

[0002] Furthermore, the invention relates to a piece of furniture comprising a furniture body, a furniture part which is mounted to be movable relative to the furniture body and a furniture drive of the type to be described.

[0003] WO 2022 / 099334 A1 discloses a furniture drive with an actuator arm assembly for moving a movable furniture part and with an adjusting device for setting the force on the actuator arm assembly. The adjusting device includes a rotatable adjusting element, wherein the force of the spring device on the actuator arm assembly can be adjusted by rotating the adjusting element. The furniture drive further includes an overload protection device that decouples the adjusting element from a transmission mechanism if the adjusting element is rotated with a torque exceeding a predetermined limit torque. This overload protection is particularly useful when the adjusting element is driven by a rotary tool such as a high-torque cordless screwdriver.The overload protection system comprises a rotatable shaft with a first toothed section, which is pressed against a corresponding second toothed section of the adjusting element by the force of a spring element in an axial direction along the shaft. A disadvantage of this design is that the two toothed sections are relatively complex to manufacture. For the overload protection system to function reliably over a long period, the toothed sections should be made of a metal that requires milling and hardening. Furthermore, the two interacting toothed sections allow only tight tolerances and therefore must be manufactured with high precision. This, of course, leads to increased costs in the mass production of the furniture drives.

[0004] Furniture drives with overload protection are also disclosed in EP 3 708 753 A1 and in WO 2020 / 232483 A1.

[0005] In WO 2020 / 232485 A1, a furniture drive for moving a movable furniture flap is disclosed, wherein the housing of the furniture drive can be integrated into a furniture panel of the furniture body.

[0006] The object of the present invention is to provide a furniture drive of the type mentioned at the outset, avoiding the disadvantages discussed above.

[0007] This is achieved according to the invention by the features of claim 1. Further advantageous embodiments of the present invention are defined in the dependent claims.

[0008] According to the invention, the overload protection system comprises a first component with a longitudinal direction and at least a second component which, at a torque above the limiting torque, is movable at least in one direction transverse to the longitudinal direction of the first component relative to the first component.

[0009] In other words, the overload protection device has at least two components that can move relative to each other, which are coupled together in a first operating position and a torque transmission is established between these components.

[0010] When the adjusting element is rotated with a torque exceeding the limit torque, the second component can be moved transversely to the longitudinal direction of the first component (i.e., in a radial direction) into a second operating position in which the two components are decoupled from each other in such a way that no torque transmission occurs. This has the advantage that the two components of the overload protection do not have to be pressed together axially by the spring element. Instead, in the event of an overload, the second component is deflected radially relative to the longitudinal axis of the first component.

[0011] The first component and the second component can be designed as separate components or as a single piece. Preferably, the first component and the second component can be connected to each other via at least one film hinge.

[0012] According to one embodiment, it can be provided that at least one holding element is provided which holds the first component and the second component in a coupled position relative to each other at a torque that is below the limiting torque.

[0013] According to a further embodiment, it can be provided that the at least one retaining element comprises at least one spring element which exerts a force on the second component in the direction of the first component.

[0014] The furniture drive can be used to drive movable furniture parts, especially doors, flaps or drawers, or to drive other movable elements, such as windows.

[0015] Further details and advantages of the present invention are explained with reference to the following description of the figures. Figs. 1a, 1b show a piece of furniture with a movable part in a perspective view and in an exploded view; Figs. 2a, 2b show two different perspective views of a furniture drive; Figs. 3a, 3b show the furniture drive in a closed position and in an open position; Figs. 4a, 4b show an adjustment device with an overload protection in two different views; Figs. 5a-5d show the overload protection in a coupled position in different views; Figs. 6a-6c show the overload protection in a decoupling position in two different views as well as the overload protection in an exploded view.

[0016] Fig. 1a Figure 1 shows a perspective view of a piece of furniture 1, which comprises a furniture body 2, a furniture part 3 mounted to move relative to the furniture body 2, and at least one furniture drive 4 for moving the movable furniture part 3. The furniture 1 has furniture panels 6 in the form of side walls, a top panel 7, and a bottom panel 8. In the illustrated embodiment, the furniture part 3 is designed as a furniture flap 3a that can be lifted relative to the furniture body 2.

[0017] In the illustrated embodiment, the furniture drive 4 is at least partially, preferably substantially completely, integrated into a furniture panel 6 of the furniture carcass 2. Of course, the furniture drive 4 can also be arranged outside the wall thickness of the furniture panel 6.

[0018] The movable furniture part 3 is mounted so as to be movable between a closed position covering the furniture body 2 and an open position raised relative to the furniture body 2.

[0019] Of course, it is also possible to integrate the furniture drive 4 into a horizontally extending furniture panel, for example in the top panel 7, the bottom panel 8 and / or in a shelf arranged between the top panel 7 and the bottom panel 8. In such a case, the movable furniture part 3 is pivotably mounted relative to the furniture body 2 about an axis that runs vertically in the mounting position.

[0020] The furniture drive 4 has an actuating arm arrangement 5 for moving the movable furniture part 3 and at least one spring device 10 ( Fig. 1b ) for applying force to the actuating arm arrangement 5.

[0021] Fig. 1b Figure 1 shows an exploded view of the furniture 1, in which two, preferably identical, furniture drives 4 are provided for moving the movable furniture part 3. Each furniture drive 4 has a housing 9 to be attached to the furniture body 2.

[0022] According to one embodiment, the housing 9 can be provided that, in an assembled state, it is received at least partially, preferably substantially completely, within a recess 11 of the side walls designed as furniture panels 6. In an assembled state, the housing 9 can be substantially flush with an end face 6a of the furniture panel 6.

[0023] The recess 11 is designed, for example, as a blind hole, whereby the housing 9 can be inserted into the pocket-shaped recess 11 of the furniture panel 6 during assembly from the front (i.e. starting from the narrow end face 6a of the furniture panel 6).

[0024] A cover 12 is provided at the front end of the housing 9, wherein at least one movable actuating arm 5a, 5b, 5c, 5d, 5e ( Fig. 2a ) the actuating arm arrangement 5 can be guided through the cover 12 in a relative position.

[0025] Fig. 2a Figure 1 shows the furniture drive 4 in a perspective view, wherein the housing 9 has at least one flat housing wall 9a that can be attached to the furniture body 2. A pivotable bearing element 14 is provided on the housing wall 9a, which is pivotably mounted about a pivot axis 13 fixed to the housing 9. The spring device 10 can thus be supported at a first end region on the fixed pivot axis 13. The spring device 10 can comprise at least one coil spring, preferably at least one compression spring, or alternatively a gas spring.

[0026] The furniture drive 4 has a transmission mechanism 35, which can be used, for example, to transmit a force from the spring device 10 to the positioning arm arrangement 5.

[0027] In the illustrated embodiment, a second end region of the spring device 10 acts on a pressure piece 20, which is pivotally connected via an adjustable point of attack 18 to an intermediate lever 16 which is pivotable about a, preferably stationary, pivot axis 15.

[0028] An adjusting device 19 allows the force exerted by the spring device 10 on the actuating arm assembly 5 to be adjusted. The adjusting device 19 comprises an adjusting element 19a rotatable about a pivot axis R, wherein the position of the point of application 18 of the spring device 10 relative to the actuating arm assembly 5, preferably along a threaded section 17, can be adjusted by rotating the adjusting element 19a about the pivot axis R.

[0029] The threaded section 17 has a longitudinal direction L. The angle between the longitudinal direction L of the threaded section 17 and the axis of rotation R of the adjusting element 19a can be changed when the adjusting arm assembly 5 is moved. A rotary movement of the adjusting element 19a can be transmitted to the threaded section 17 by means of an angularly movable coupling device 25, so that the threaded section 17 is set into a rotational movement and thereby the point of application 18 is moved along the threaded section 17.

[0030] The angularly movable coupling device 25 can comprise at least one elastic element, preferably a bellows, a rubber molded element, a coil spring coupling, and / or at least one transmission, preferably a bevel gear transmission, and / or a joint, preferably a universal joint or cardan joint. The angularly movable coupling device 25 allows for a particularly compact arrangement because the components of the furniture drive 4 can be nested within one another.

[0031] Preferably, the adjusting element 19a of the adjusting device 19 is arranged in a front area of ​​the housing 9 when the furniture drive 4 is mounted, facing the movable furniture part 3. This allows the adjusting element 19a to be conveniently operated from the front using a tool.

[0032] In the illustrated embodiment, at least one shaft 28, driven by the adjusting element 19a, is provided for driving the threaded section 17, wherein the at least one shaft 28 is slidably mounted in or along a guide 30, preferably an elongated hole, relative to the housing 9. In this way, compensating movements of components of the furniture drive 4, which are caused by the angularly movable coupling device 25, can be at least partially compensated.

[0033] The shaft 28 is arranged in or on a bearing device 29, wherein the guide 30 is arranged on the bearing device 29 and a pin 32, which is fixedly mounted on the housing 9, engages in the guide 30 of the bearing device 29. During a compensating movement, the bearing device 29 is movable relative to the fixed pin 32.

[0034] The adjusting arm arrangement 5 comprises at least one adjusting arm 5a, 5b, 5c, 5d, 5e, preferably several adjusting arms 5a, 5b, 5c, 5d, 5e, for moving the movable furniture part 3. A fitting 21 is to be attached to the movable furniture part 3, wherein the fitting 21 has at least one or more fastening points 22 and can be detachably locked to an adjusting arm 5e of the adjusting arm arrangement 5. Fig. 2a The locked state between the adjusting arm 5e and the fitting part 21 is shown.

[0035] A cover 12 is provided at the front end of the housing wall 9a, which has at least one laterally projecting flange 12a. In the illustrated embodiment, the flange 12a is essentially ring-shaped and forms a depth stop for the housing 9 that can be placed against an end face 6a of the furniture panel 6.

[0036] Fig. 2b shows the furniture drive 4 according to Fig. 2a , wherein the housing 9 is closed by a second housing wall 9b. The first housing wall 9a and the second housing wall 9b are each flat and designed to rest against a furniture carcass 2 and together form a substantially cuboid housing 9. The housing walls 9a, 9b are spaced parallel to each other, with a front opening 23 formed between the housing walls 9a, 9b.

[0037] The cover 12 is arranged in the area of ​​this opening 23 and allows a tool to pass through for actuating the adjusting device 19.

[0038] Fig. 3a Figure 1 shows the furniture drive 4 with the housing 9 in a side view. The threaded section 17 is arranged on an intermediate lever 16, which is pivotally mounted about a pivot axis 15 fixed to the housing 9. In the figure shown, the spring device 10 exerts a minimal torque on the adjusting arm assembly 5 because the point of application 18 of the spring device 10 is located in an area adjacent to the pivot axis 15 of the intermediate lever 16. An imaginary line connecting the pivot axis 15 of the intermediate lever 16 and the point of application 18 of the spring device 10 forms a relatively short lever arm, resulting in a minimal torque acting on the adjusting arm assembly 5.

[0039] The axis of rotation R of the adjusting element 19a of the adjusting device 19 and the longitudinal direction L of the threaded section 17 form an angle with each other, which can be changed when the adjusting arm assembly 5 is moved. One advantage of this design is evident from the Fig. 3a This can be clearly seen because, in the closed position of the furniture drive 4 shown, the adjusting arms 5a-5e of the adjusting arm arrangement 5 together with the spring device 10 and the adjusting device 19 assume a very compact position relative to each other due to the angularly movable arrangement of the axis of rotation R and the longitudinal direction L.

[0040] The adjusting element 19a and the rotatable threaded section 17 are thus mounted so that they can move angularly relative to each other when the adjusting arm assembly 5 is moved, allowing the adjusting device 19 for setting the force of the spring device 10 and the adjusting arm assembly 5 to assume different positions relative to each other. This allows the components of the furniture drive 4 to be nested within each other and consequently arranged closer together. In this way, the furniture drive 4 can be built more compactly, the adjustment range of the spring device 10 on the threaded section 17 can be increased, and higher performance ranges of the furniture drive 4 can be covered.

[0041] The housing 9 can be essentially rectangular, preferably with a ratio of the length L1 of the housing 9 to its height H1 greater than 1:0.7, preferably greater than 1:0.5. Such dimensions allow for a reduced height H1 of the housing 9. This also allows for a reduced height of the recess 11 ( Fig. 1b ) the furniture panels 6 are dimensioned to a small extent, whereby the manufacturing effort of the recess 11 and a weakening of the furniture panel 6 are minimal.

[0042] Fig. 3b shows the furniture drive 4 according to Fig. 3a with a minimum force setting of the spring device 10, wherein the adjusting arm arrangement 5 with the adjusting arms 5a-5e is in an open position. It can be seen that the angle which the axis of rotation R of the adjusting element 9 and the longitudinal direction L of the threaded section 17 enclose with respect to each other, in relation to the in Fig. 3a The shown closed position has been reduced.

[0043] The actuating arm arrangement 5 comprises a first actuating arm 5a pivotable about a first pivot axis 26 and at least one second actuating arm 5b pivotably mounted about a second pivot axis 27. The first pivot axis 26 and the second pivot axis 27 are spaced apart from each other in a longitudinal direction L2 of the housing 9, with the second pivot axis 27 being located in a front region of the housing 9 relative to the first pivot axis 26.

[0044] The intermediate lever 16 is directly connected to the second (front) adjusting arm 5b via a thrust lever 24, which is preferably arc-shaped. The first adjusting arm 5a is therefore not directly connected to the thrust lever 24 via a pivot axis, but is instead guided slidably within the thrust lever 24. This is evident from Fig. 2a clearly visible. In this way, an improved and direct force transmission from the spring device 10 to the adjusting arm assembly 5 is enabled.

[0045] Fig. 4a Figure 19 shows the adjusting device 19 with the rotatable adjusting element 19a and an overload protection device 33. The overload protection device 33 is designed such that when the adjusting element 19a is rotated with a torque below a predetermined limit torque, the adjusting element 19a couples with the transmission mechanism 35. When the adjusting element 19a is rotated with a torque above the limit torque, the adjusting element 19a can be disengaged from the transmission mechanism 35 by the overload protection device 33.

[0046] The adjusting element 19a can be driven by a rotary tool 36, for example a cordless screwdriver. The rotary motion of the adjusting element 19a can be transmitted to the shaft 28, whereby the threaded section 17 can be set into a rotary motion via the angularly movable coupling device 25. In this way, the point of application 18 of the spring device 10 can be moved along the threaded section 17. In the illustrated embodiment, the threaded section 17 is mounted on the intermediate lever 16, which is pivotable about the pivot axis 15.

[0047] Fig. 4b shows the view according to Fig. 4a , whereby one housing part is not shown, thus revealing the overload protection 33 in more detail. The overload protection 33 comprises a first component 37a with a longitudinal direction L3 and a second component 37b, which are movable relative to each other between a coupled position and a decoupling position.

[0048] When the adjusting element 19a is rotated with a torque that is below a predetermined limit torque, the adjusting element 19a is coupled to the transmission mechanism 35.

[0049] When the adjusting element 19a is rotated above the limit torque, the adjusting element 19a can be decoupled from the transmission mechanism 35 by allowing the second component 37b to be moved at least in one direction X transverse to the longitudinal direction L3 of the first component 37a relative to the first component 37a.

[0050] According to possible embodiments, it can be provided that the first component 37a and / or the second component 37b are at least partially essentially cylindrical, and / or together form an essentially cylindrical shape, and / or are made of plastic, and / or are manufactured using an injection molding process.

[0051] The two components 37a, 37b can be designed as separate components 37a, 37b. According to an alternative embodiment, the two components 37a, 37b can be connected to each other via at least one film hinge 39.

[0052] In the illustrated embodiment, at least one retaining element 38 is provided which holds the first component 37a and the second component 37b in a coupled position relative to each other at a torque that is below the limit torque.

[0053] The at least one retaining element 38 can comprise at least one spring element 38a, which exerts a force on the second component 37b in the direction of the first component 37a, preferably wherein the spring element 38a is at least partially ring-shaped, and / or is designed as an O-ring, and / or is at least partially hollow-cylindrical, and / or has a width between 0.1 mm and 3.0 mm, preferably a width of 2.0 mm, and / or has a wall thickness between 0.1 mm and 2.0 mm, preferably a wall thickness of 1.0 mm, and / or has an outer diameter of less than 8.0 mm, preferably less than 7.5 mm, particularly preferably less than or equal to 7.0 mm, and / or is made of plastic, preferably POM and / or TPU, and / or is manufactured by an injection molding process, and / or is at least partially stretchable in a radial direction, preferably elastically.

[0054] In the illustrated embodiment, the first component 37a of the overload protection device 33 is formed in one piece together with the shaft 28. However, the component 37a and the shaft 28 can also be designed as separate components.

[0055] The adjusting element 19a of the adjusting device 19 can be integrally formed with at least one component 37a, 37b, preferably with both components 37a, 37b. Therefore, a separate adjusting element 19a can be omitted. Of course, a separate adjusting element 19a can also be provided.

[0056] According to one embodiment, it can be provided that the retaining element 38 is displaceably mounted at least section by section in the longitudinal direction L3 of the first component 37a relative to the first component 37a and / or second component 37b, preferably wherein the limiting torque is adjustable by a displacement of the retaining element 38.

[0057] According to one embodiment, the limiting torque can be between 0.5 Nm and 4.0 Nm, preferably between 0.8 Nm and 1.2 Nm.

[0058] Fig. 5a-5d The overload protection device 33 is shown in different views.

[0059] Fig. 5a Figure 1 shows a perspective view of the two components 37a, 37b of the overload protection device 33, with the rotary tool 36 inserted into the two components 37a, 37b. By rotating the rotary tool 36, at least one of the two components 37a, 37b can be driven.

[0060] The first component 37a can be manufactured as a single piece together with the shaft 28. Alternatively, it is also possible that the first component 37a and the shaft 28 are designed as separate elements.

[0061] The first component 37a can have at least one toothing 41 by which a rotational movement of the first component 37a can be transmitted to other components of the transmission mechanism 35 of the furniture drive 4.

[0062] The first component 37a and the second component 37b can be designed as separate components 37a, 37b. Alternatively, it is possible that the two components 37a, 37b are formed together as a single piece.

[0063] For example, it may be provided that the first component 37a and the second component 37b are connected to each other via at least one film hinge 39.

[0064] The retaining element 38 allows the two components 37a, 37b to be held in a coupled position relative to each other at a torque that is below the limit torque, in which a torque can be transmitted to the shaft 28.

[0065] The adjusting element 19a of the adjusting device 19 can have at least one actuating contour 40, preferably wherein the actuating contour 40 at least partially has a six-round profile, and / or has a diameter of less than or equal to 3.86 mm, and / or is arranged only on the first component 37a, and / or is arranged at least partially on the first component 37a and at least partially on the second component 37b, and / or is arranged on an end face of the adjusting element.

[0066] Fig. 5b shows the embodiment of the overload protection device 33 according to Fig. 5a in a cross-section. The rotary tool 36 inserted into the two components 37a and 37b is visible, whereby only the first component 37a has an actuation contour 40 for the rotary tool 36. The second component 37b, on the other hand, has a circular inner contour 42. Thus, rotation of the rotary tool 36 is only transmitted to the first component 37a. In this way, a lower torque can be transmitted, so that the limit torque of the overload protection 33 can be reduced for various applications.

[0067] Fig. 5c Figure 1 shows an embodiment of an overload protection device 33, wherein the retaining element 38 is in a rear end position relative to the two components 37a, 37b.

[0068] The retaining element 38 can be displaced relative to the first component 37a and / or second component 37b by means of at least one actuating device 43. In this way, the limit torque of the overload protection device 33 can be adjusted.

[0069] According to possible embodiments, it can be provided that the at least one actuating device 43 can be actuated from a direction parallel and / or transverse to the longitudinal direction L3 of the first component 37a, and / or the furniture drive 4 has a housing 9, wherein the overload protection 33 is arranged in the housing 9 and the retaining element 38 can be actuated from an outside of the housing 9 via the actuating device 43.

[0070] Preferably, the retaining element 38 can be provided that, in the case of a furniture drive 4 arranged on or in the furniture panel 6, it is directly accessible for manual operation from the end face of the furniture panel 6 via the actuating device 43.

[0071] The actuating device 43 can, for example, have a sliding and / or rotatable actuating element for adjusting the position of the retaining element 38. The actuating element of the actuating device 43 can, for example, be arranged on the housing 9 of the furniture drive 4, preferably on the front end face of the housing 9.

[0072] Fig. 5d shows the embodiment of the overload protection device 33 according to Fig. 5c , wherein the retaining element 38, preferably in the form of the spring element 38a, is located in a forward end position relative to the two components 37a, 37b. In the position according to Fig. 5d is in direct comparison with the Fig. 5c A higher torque can be transmitted.

[0073] Fig. 6a Figure 1 shows a perspective view of the overload protection device 33 in a decoupling position, where the transmission of torque is interrupted. The rotary tool 36, inserted into the two components 37a and 37b, can be seen; here it is rotated with a torque above a predetermined limit torque.

[0074] In this case, the rotary tool 36 slips off the actuating contour 40 of the first component 37a, whereby the projections of the rotary tool 36 are no longer engaged with the corresponding recesses of the actuating contour 40. After a holding force specified by the holding element 38 is triggered, the second component 37b is lifted by the first component 37a in direction X, thereby interrupting the transmission of a torque.

[0075] The first component 37a and the second component 37b are arranged relative to each other in a coupled position when the torque is below the limit torque and in a decoupling position when the torque is above the limit torque, wherein the two components 37a, 37b are further apart from each other in a direction X transverse to the longitudinal direction L3 of the first component 37a in the decoupling position than in the coupled position.

[0076] Fig. 6b The overload protection 33 shows according to Fig. 6a in a cross-section. It can be seen that when a permissible limit torque is exceeded, the second component 37b is moved in a direction X perpendicular to the longitudinal direction L3 of the first component 37a by the difference ΔX, forming a gap, and the turning tool 36 is no longer in engagement with the actuating contour 40 of the first component 37a.

[0077] Fig. 6cThe overload protection device 33 is shown in an exploded view. The first component 37a can have at least one recess 44 in which the second component 37b can be arranged, at least partially. However, the arrangement of a film hinge 39 for the articulated connection of the two components 37a and 37b can generally be omitted.

[0078] At least one stop element 45 can be arranged on the first component 37a and / or on the second component 37b, which limits a movement of the retaining element 38 in the longitudinal direction L3 of the first component 37a.
