Description

Technical Field

[0001] The invention relates to a furniture drive for moving a furniture component which is movably supported relative to a furniture body, comprising:

[0002] - a setting device having at least one rotatably mounted setting element;

[0003] - a transmission mechanism for transmitting the force of the setting element;

[0004] - At least one overload protection device, which couples the setting element to the transmission mechanism when the setting element rotates with a torque lower than a predetermined limit torque, and decouples the setting element from the transmission mechanism when the setting element rotates with a torque higher than the limit torque, preferably so that no torque transfer occurs between the setting element and the transmission mechanism.

[0005] The invention further relates to a piece of furniture having a furniture carcass, a furniture part which is mounted displaceably relative to the furniture carcass and a furniture drive of the type which will be described in the following. Background Art

[0006] A furniture drive is disclosed in AT 524391A1, which has an actuator arm device for moving a movable furniture part and a setting device for setting the force applied to the actuator arm device. The setting device includes a rotatable setting element, wherein the force applied by a spring device to the actuator arm device can be set by rotating the setting element. The furniture drive also includes an overload protection device, which decouples the setting element from the transmission mechanism when the setting element rotates with a torque higher than a predetermined limit torque. This overload protection device is particularly useful when the setting element is driven by a rotating tool in the form of an electric screwdriver with high torque. The overload protection device includes a rotatable shaft with a first tooth portion, which is pressed against a corresponding second tooth portion of the setting element in the axial direction of the shaft by the force of a spring element. The disadvantage is that these two tooth portions are relatively complicated to produce. For the long-term function of the overload protection device, these tooth portions should be made of a metal that must be milled and hardened. In addition, the two interacting tooth portions only allow small tolerances and must therefore be manufactured very accurately. This naturally also leads to an increase in the costs of mass production of furniture drives.

[0007] Furniture drives with overload protection are also disclosed in EP 3 708 753 A1 and WO 2020 / 232483 A1.

[0008] WO 2020 / 232485 A1 discloses a furniture drive for moving a movably supported furniture flap, wherein the housing of the furniture drive can be integrated into a furniture panel of the furniture body. Summary of the invention

[0009] The object of the present invention is to provide a furniture drive of the above-mentioned type which avoids the above-discussed disadvantages.

[0010] According to the invention, this object is achieved by the features of claim 1. Further advantageous embodiments of the invention are defined in the dependent claims.

[0011] According to the invention, the overload protection device has a first component with a longitudinal direction and at least one second component which is movable relative to the first component at a torque above the limit torque at least in a direction transverse to the longitudinal direction of the first component.

[0012] In other words, the overload protection device has at least two components which are movable relative to one another, which are coupled to one another in a first operating position and between which a torque transmission is established.

[0013] When the setting element is rotated with a torque higher than the limit torque, the second component can be moved transversely to the longitudinal direction of the first component (i.e. in the radial direction) to a second operating position, in which the two components are decoupled from each other so that no torque transmission occurs. This has the advantage that the two components of the overload protection device do not need to be pressed against each other in the axial direction by a spring element. Instead, the second component is deflected in the radial direction relative to the longitudinal axis of the first component in the case of overload.

[0014] It can be provided that the first component and the second component are configured as independent components, or are configured together in one piece. Preferably, it can be provided that the first component and the second component are connected to each other via at least one film hinge.

[0015] According to one embodiment, it can be provided that at least one retaining element is provided which retains the first component and the second component in a coupled position relative to one another at a torque below a limit torque.

[0016] According to a further embodiment, it can be provided that 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.

[0017] The furniture drive can be used to drive movable furniture parts, in particular doors, flaps or drawers, or also to drive other movable elements, for example windows. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1a A perspective view of a piece of furniture 1 is shown, which has a furniture carcass 2, a furniture part 3 which is mounted displaceably relative to the furniture carcass 2, and at least one furniture drive 4 for moving the movable furniture part 3. The piece of furniture 1 has a furniture panel 6 in the form of side walls, an upper base 7 and a lower base 8. In the exemplary embodiment shown, the furniture part 3 is designed as a furniture flap 3a which can be lifted relative to the furniture carcass 2.

[0026] In the embodiment shown, the furniture drive 4 is at least partially, preferably substantially completely, integrated in the furniture plate 6 of the furniture carcass 2. Of course, the furniture drive 4 can also be arranged outside the wall thickness of the furniture plate 6.

[0027] The movable furniture part 3 is mounted so that it can be moved between a closed position, in which it covers the furniture carcass 2 , and an open position, in which it is raised relative to the furniture carcass 2 .

[0028] Naturally, it is also possible to integrate the furniture drive 4 in a horizontally extending furniture panel, i.e. for example in the upper base plate 7, the lower base plate 8 and / or a shelf arranged between the upper base plate 7 and the lower base plate 8. In this case, the movable furniture part 3 is pivotably mounted relative to the furniture carcass 2 about an axis extending vertically in the assembly position.

[0029] The furniture drive 4 has an actuator arm 5 for moving the movable furniture part 3 and at least one spring device 10 ( Figure 1b ) is used to apply force to the actuator arm device 5.

[0030] Figure 1b An exploded view of a piece of furniture 1 is shown, in which two furniture drives 4 are provided for moving a movable furniture part 3 , which are preferably designed identically. The furniture drives 4 each have a housing 9 to be fastened to the furniture carcass 2 .

[0031] According to one embodiment, it can be provided that the housing 9 in the assembled state is at least partially, preferably substantially completely, accommodated in a recess 11 designed as a side wall of the furniture panel 6. In the assembled state, the housing 9 can be substantially flush with the end face 6a of the furniture panel 6.

[0032] For example, the recess 11 is designed as a blind hole, wherein during assembly the housing 9 can be inserted from the front, ie starting from the narrow end face 6 a of the furniture panel 6 , into the pocket-shaped recess 11 of the furniture panel 6 .

[0033] A cover 12 is provided at the front end region of the housing 9, in which at least one movably supported actuating arm 5a, 5b, 5c, 5d, 5e ( Figure 2a ) can be guided through the cover 12 in a relative position.

[0034] Figure 2a A perspective view of a furniture drive 4 is shown, wherein the housing 9 has at least one housing wall 9a which is of planar design and can be attached to the furniture carcass 2. A pivotable bearing component 14 is arranged on the housing wall 9a, which is pivotably supported about a fixed joint axis 13 on the housing 9. The spring device 10 can thus be supported at a first end region on the fixed joint axis 13. The spring device 10 can include at least one helical spring, preferably at least one compression spring, or alternatively a gas spring.

[0035] The furniture drive 4 has a transmission mechanism 35 which can be provided, for example, for transmitting the force from the spring device 10 to the actuating arm means 5 .

[0036] In the exemplary embodiment shown, the second end region of the spring device 10 acts on a pressure piece 20 which is connected in an articulated manner via an adjustable point of action 18 to an intermediate lever 16 which is pivotable about a preferably stationary articulation axis 15 .

[0037] The force exerted by the spring device 10 on the actuating arm means 5 can be set by means of the setting device 19. The setting device 19 comprises a setting element 19a rotatable about an axis of rotation R, wherein the position of the point of action 18 of the spring device 10 relative to the actuating arm means 5, preferably along the threaded section 17, can be set by rotating the setting element 19a about the axis of rotation R.

[0038] The threaded section 17 has a longitudinal direction L. The angle enclosed between the longitudinal direction L of the threaded section 17 and the rotation axis R of the setting element 19a is variable when the actuating arm 5 is moved. By means of the angularly movable coupling device 25, the rotational movement of the setting element 19a can be transmitted to the threaded section 17, so that the threaded section 17 is set into rotational movement and the point of action 18 is thus displaced along the threaded section 17.

[0039] The angularly movable coupling 25 can have: at least one elastic element, preferably a bellows; a rubber profile element; a helical spring coupling; and / or at least one gear transmission, preferably a bevel gear transmission; and / or a joint, preferably a cross joint or a universal joint. The angularly movable coupling 25 allows a particularly compact arrangement to be achieved, since the components of the furniture drive 4 can be nested in one another.

[0040] It is preferably provided that the setting element 19a of the setting device 19 is arranged facing the movable furniture part 3 and in the front area of ​​the housing 9 in the assembled state of the furniture drive 4. In this way, the setting element 19a can be easily actuated from the front by means of a tool.

[0041] In the embodiment shown, at least one shaft 28 is provided which can be driven by the setting element 19a for driving the threaded section 17, wherein the at least one shaft 28 is mounted slidably in a guide 30 or along the guide, preferably an oblong hole, relative to the housing 9. In this way, compensating movements of components of the furniture drive 4 caused by the angularly movable coupling device 25 can be at least partially compensated.

[0042] The shaft 28 is arranged in or on a bearing 29, wherein a guide 30 is arranged on the bearing 29 and a pin 32 fixedly supported on the housing 9 engages in the guide 30 of the bearing 29. In a compensating movement, the bearing 29 can be moved relative to the fixed pin 32.

[0043] The actuator arm device 5 comprises at least one actuator arm 5a, 5b, 5c, 5d, 5e, preferably a plurality of actuator arms 5a, 5b, 5c, 5d, 5e, for moving the movable furniture component 3. A hardware accessory 21 needs to be fixed at the movable furniture component 3, wherein the hardware accessory 21 has at least one or more fixing points 22 and can be locked with the actuator arm 5e of the actuator arm device 5 in a detachable manner. Figure 2a , the locking state between the actuating arm 5 e and the hardware fitting 21 is shown.

[0044] A cover 12 is provided at the front end of the housing wall 9a, which has at least one flange 12a protruding laterally. In the embodiment shown, the flange 12a is configured to be substantially annular and to form a depth stop for the housing 9 to fit the end face 6a of the furniture panel 6.

[0045] Figure 2b Shown according to Figure 2a The furniture drive 4, wherein the housing 9 is closed by the second housing wall 9b. The first housing wall 9a and the second housing wall 9b are each configured to be flat and fit the furniture body 2, and together form a substantially rectangular housing 9. The housing walls 9a, 9b are spaced apart from each other in parallel, wherein a front opening 23 is formed between the housing walls 9a, 9b.

[0046] The cover 12 is arranged in the region of this opening 23 and allows a tool to pass through in order to actuate the setting device 19 .

[0047] Figure 3a A side view of a furniture drive 4 with a housing 9 is shown. The threaded section 17 is arranged on an intermediate lever 16, which is pivotably mounted about an articulation axis 15 arranged in a fixed position on the housing 9. In the illustrated figure, the spring device 10 exerts a minimal torque on the actuating arm device 5, since the point of action 18 of the spring device 10 is located in the region adjacent to the articulation axis 15 of the intermediate lever 16. The imaginary connecting line between the articulation axis 15 of the intermediate lever 16 and the point of action 18 of the spring device 10 forms a relatively short lever arm, so that a minimal torque is exerted on the actuating arm device 5.

[0048] The rotation axis R of the setting element 19a of the setting device 19 and the longitudinal direction L of the threaded section 17 enclose an angle with each other, which angle is variable when the actuating arm device 5 moves. The advantages of this design structure are Figure 3a It can be clearly seen that in the closed position of the furniture drive 4 shown, due to the angularly movable arrangement of the rotation axis R and the longitudinal direction L, the actuating arms 5a-5e of the actuating arm device 5 together with the spring device 10 and the setting device 19 only occupy a very compact position relative to each other.

[0049] Thus, the setting element 19a and the rotatable threaded section 17 are supported angularly displaceably relative to each other when the actuating arm device 5 moves, so that the setting device 19 and the actuating arm device 5 for setting the force of the spring device 10 can assume different positions relative to each other. The components of the furniture drive 4 are thus nestable and can be arranged more closely to each other. In this way, the furniture drive 4 can be constructed more compactly, the setting path of the spring device 10 at the threaded section 17 can be increased, and a higher power range of the furniture drive 4 can be covered.

[0050] The housing 9 can be designed to be substantially rectangular, wherein preferably the ratio of the length L1 of the housing 9 to the height H1 of the housing 9 is greater than 1 to 0.7, preferably greater than 1 to 0.5. This dimensioning can achieve a reduced height H1 of the housing 9. Figure 1b ) can also be designed to be small in height, wherein the manufacturing costs of the recess 11 and the weakening of the strength of the furniture panel 6 are low.

[0051] Figure 3b Shown according to Figure 3a Furniture drive 4, wherein the force of the spring device 10 is set to a minimum, wherein the actuating arm device 5 with the actuating arms 5a-5e is in the open position. It can be seen that the angle enclosed by the rotation axis R of the setting element 9 and the longitudinal direction L of the threaded section 17 is relative to Figure 3a The closed position shown in is smaller.

[0052] The actuator arm device 5 has a first actuator arm 5a pivotable around a first hinge axis 26, and at least one second actuator arm 5b pivotable around a second hinge axis 27. The first hinge axis 26 and the second hinge axis 27 are spaced apart from each other in the longitudinal direction L2 of the housing 9, wherein the second hinge axis 27 is arranged in a front area of ​​the housing 9 relative to the first hinge axis 26.

[0053] The intermediate lever 16 is directly connected to the second (front) actuating arm 5b via a push rod 24 which is preferably configured in an arc shape. Therefore, the first actuating arm 5a is not directly connected to the push rod 24 via an articulated axis, but is slidably guided inside the push rod 24. This is Figure 2a In this way, an improved and direct force transmission of the spring device 10 to the actuating arm device 5 is possible.

[0054] Figure 4a The setting device 19 is shown to have a rotatable setting element 19a and an overload protection device 33. The overload protection device 33 is configured so that when the setting element 19a rotates at a torque lower than a predetermined limit torque, the setting element 19a is coupled to the transmission mechanism 35. When the setting element 19a rotates at a torque higher than the limit torque, the setting element 19a can be decoupled from the transmission mechanism 35 through the overload protection device 33.

[0055] The setting element 19a can be driven by a rotating tool 36, such as an electric screwdriver. The rotational movement of the setting element 19a can be transmitted to the shaft 28, wherein the threaded section 17 can be put into rotational movement via the angularly movable coupling device 25. In this way, the point of action 18 of the spring device 10 can be moved along the threaded section 17. The threaded section 17 is supported on the intermediate lever 16 that can be pivoted about the articulation axis 15 in the embodiment shown.

[0056] Figure 4b Shown according to Figure 4a , wherein the housing components are not shown, so that the overload protection device 33 is more prominent. The overload protection device 33 comprises a first component 37a and a second component 37b having a longitudinal direction L3, which are movable relative to each other between a coupled position and a decoupled position.

[0057] When the setting element 19 a rotates at a torque lower than a predetermined limit torque, the setting element 19 a is coupled to the transmission mechanism 35 .

[0058] When the setting element 19a rotates above the limit torque, the setting element 19a can be decoupled from the transmission mechanism 35 by making the second component 37b movable relative to the first component 37a at least in the direction X transverse to the longitudinal direction L3 of the first component 37a.

[0059] According to a possible embodiment, it can be configured that the first component 37a and / or the second component 37b

[0060] - is configured to be substantially cylindrical at least in certain sections, and / or

[0061] - are jointly configured to be substantially cylindrical in shape, and / or

[0062] - made of plastic, and / or

[0063] -Made in injection molding process.

[0064] The two components 37a, 37b can be designed as mutually independent 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.

[0065] In the embodiment shown, at least one retaining element 38 is provided which, at a torque below the limit torque, holds the first component 37a and the second component 37b in the coupled position relative to one another.

[0066] The at least one retaining element 38 may include 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

[0067] - is configured to be annular at least in certain sections, and / or

[0068] - is configured as an O-ring, and / or

[0069] - is configured to be hollow cylindrical at least in certain sections, and / or

[0074] - manufactured in an injection molding process, and / or

[0075] - at least in certain sections, stretchable in radial direction, preferably elastically stretchable.

[0076] In the exemplary embodiment shown, the first component 37a of the overload protection device 33 is designed integrally with the shaft 28. However, the component 37a and the shaft 28 can also be designed as separate components from one another.

[0077] The setting element 19a of the setting device 19 can be implemented as a single piece with at least one component 37a, 37b, preferably with both components 37a, 37b. Therefore, it is possible to dispense with arranging the setting element 19a separately from the components 37a, 37b. Naturally, however, a setting element 19a separate from the components 37a, 37b can also be provided.

[0078] According to one embodiment, it can be provided that at least some sections of the retaining element 38 are slidably supported relative to the first component 37a and / or the second component 37b in the longitudinal direction L3 of the first component 37a, preferably wherein the limit torque is settable by sliding the retaining element 38.

[0079] According to one embodiment, it can be provided that the limit torque is between 0.5 Nm and 4.0 Nm, preferably between 0.8 Nm and 1.2 Nm.

[0080] Figures 5a to 5d Different views of the overload protection device 33 are shown.

[0081] Figure 5a A perspective view of two components 37a, 37b of an overload protection device 33 is shown, into which the rotating tool 36 has been inserted. By rotating the rotating tool 36, at least one of the two components 37a, 37b can be driven.

[0082] The first component 37a can be designed in one piece with the shaft 28. Alternatively, it is also possible that the first component 37a and the shaft 28 can be designed as separate elements from each other.

[0083] The first component 37 a can have at least one toothing 41 , via which a rotational movement of the first component 37 a can be transmitted to further components of the transmission mechanism 35 of the furniture drive 4 .

[0084] The first component 37a and the second component 37b can be configured as components 37a, 37b that are independent of each other. Alternatively, it is possible that the two components 37a, 37b are configured together in one piece.

[0085] For example, it can be provided that the first component 37 a and the second component 37 b are connected to one another via at least one film hinge 39 .

[0086] By means of the retaining element 38 , the two components 37 a , 37 b can be held relative to one another in a coupled position at a torque below a limit torque, in which the torque can be transmitted to the shaft 28 .

[0087] The setting element 19a of the setting device 19 can have at least one actuation contour 40, wherein the actuation contour 40 is preferably

[0088] - having a hexacircular profile at least in certain sections, and / or

[0089] - has a diameter less than or equal to 3.86 mm, and / or

[0090] - arranged only at the first component 37a, and / or

[0091] - at least partially arranged at the first component 37a and at least partially arranged at the second component 37b, and / or

[0092] - arranged on an end face of the setting element.

[0093] Figure 5b Shown according to Figure 5a A cross section of an embodiment of an overload protection device 33 of FIG. A rotating tool 36 inserted into two parts 37a, 37b can be seen, wherein only the first part 37a has an actuating contour 40 for the rotating tool 36. The second part 37b, on the other hand, has a perfectly circular inner contour 42. Therefore, the rotation of the rotating tool 36 is only transmitted to the first part 37a. In this way, a smaller torque can be transmitted, so that the limit torque of the overload protection device 33 can be reduced for different applications.

[0094] Figure 5cAn embodiment of the overload protection device 33 is shown in which the retaining element 38 is in a rearward position relative to the two components 37a and 37b.

[0095] The holding element 38 can be slidable relative to the first component 37a and / or the second component 37b by means of at least one actuating device 43. In this way, the limit torque 33 of the overload protection device can be set.

[0096] According to a possible embodiment, it can be set as:

[0097] at least one manipulator 43 is manipulatable in a direction parallel to and / or transverse to the longitudinal direction L3 of the first component 37a, and / or

[0098] The furniture drive 4 has a housing 9 , wherein the overload protection device 33 is arranged in the housing 9 and the holding element 38 is actuatable from outside the housing 9 via an actuation device 43 .

[0099] It can preferably be provided that, when the furniture drive 4 is arranged on or in the furniture panel 6 , the holding element 38 is directly accessible via the actuating device 43 from the end face of the furniture panel 6 for manual actuation.

[0100] The actuating device 43 can, for example, have a slidable and / or rotatable actuating element for setting the position of the holding 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 face of the housing 9.

[0101] Figure 5d Shown according to Figure 5c Embodiment of the overload protection device 33, in which the retaining element 38, preferably in the form of a spring element 38a, is in a front position relative to the two parts 37a, 37b. Figure 5d location, and Figure 5c In direct comparison, higher torque can be transmitted.

[0102] Figure 6a A perspective view of the overload protection device 33 is shown in the decoupled position, in which the transmission of torque is interrupted. A rotating tool 36 inserted into the two components 37a, 37b can be seen, which is rotated here with a torque above a predetermined limit torque.

[0103] In this case, the rotating tool 36 slides off the actuating contour 40 of the first component 37a, wherein the protruding portion of the rotating tool 36 no longer engages with the corresponding recessed portion of the actuating contour 40. After triggering the retaining force predetermined by the retaining element 38, the second component 37b is lifted from the first component 37a in the direction X, so that the transmission of torque can be interrupted.

[0104] The first component 37a and the second component 37b are arranged relative to each other in a coupled position at a torque below the limit torque, and in an uncoupled position at a torque above the limit torque, wherein the two components 37a, 37b are spaced further apart from each other in a direction X transverse to the longitudinal direction L3 of the first component 37a in the uncoupled position than in the coupled position.

[0105] Figure 6b Shown according to Figure 6a 33. It can be seen that, in the case of gap formation, when the permissible limit torque is exceeded, the second component 37b has moved a difference ΔX relative to the first component 37a in the direction X transverse to the longitudinal direction L3 of the first component 37a, and the rotating tool 36 no longer engages with the actuating contour 40 of the first component 37a.

[0106] Figure 6c An exploded view of the overload protection device 33 is shown. The first component 37a can have at least one recess 44, in which the second component 37b can be arranged at least in certain sections. However, in principle, the film hinge 39 for articulating the two components 37a, 37b can be omitted.

[0107] At least one stop element 45 may be arranged on the first component 37 a and / or the second component 37 b , which stops the movement of the retaining element 38 in the longitudinal direction L3 of the first component 37 a .
