Technical Field

[0001] This invention relates to a furniture drive system for movable furniture components, comprising: a carrier for mounting the furniture drive system on a furniture body; an adjusting arm device movably, preferably rotatably, supported on the carrier, the adjusting arm device being connectable to the movable furniture component; an electric motor connected to or capable of connecting to the adjusting arm device, and capable of at least partially moving the adjusting arm device; at least one drive device separate from the electric motor, by which force can be applied to the adjusting arm device; an adjusting device, by which the force applied to the adjusting arm device by the at least one drive device can be adjusted; and a control device, by which the electric motor can be controlled. Furthermore, this invention relates to furniture having such a furniture drive system. Furthermore, this invention also relates to a method for operating such a furniture drive system. Background Technology

[0002] For decades, furniture drive systems with adjustable arm mechanisms have been used to move furniture covers that can rotate or pivot about a horizontal axis or move along a vertical plane. Examples of such furniture fittings are given in WO 2012 / 155165 A2 and WO 2011 / 020130 A1.

[0003] Furthermore, furniture drive systems are known in which two separate structural units exist: a mechanical adjustment unit (including a drive mechanism) and an electric drive unit. Examples of these are given by EP 3 443 191 B1 and AT 519 935A1.

[0004] Importantly, in such furniture drive systems, the same system can be used in the same way with movable furniture parts of different sizes and weights. This is achieved by adjusting the various parameters (e.g., force) of the drive unit and / or electric motor via an adjustment mechanism. In existing furniture drive systems, a mismatch may occur between the effect produced by the drive unit and the driven movable furniture part. This can, in some cases, lead to damage to the movable furniture part or even accidents involving the person operating it.

[0005] Other furniture drive systems are known from documents AT 12191 U and EP 2 949 852 A1. Summary of the Invention

[0006] Therefore, the objective of this invention is to provide an improved furniture drive system and an improved method compared to the prior art. In particular, it should facilitate adjustment and prevent errors during adjustment.

[0007] This is addressed by a furniture drive system. Therefore, according to the present invention, a furniture drive system for movable furniture components is provided, the furniture drive system having:

[0008] - A carrier for mounting the furniture drive system on the furniture body.

[0009] - An adjustable arm device movably supported on the carrier, the adjustable arm device being connectable to movable furniture components.

[0010] - An electric motor, connected to the adjusting arm device, which enables at least partial movement of the adjusting arm device.

[0011] - At least one drive unit separate from the electric motor, which enables force to be applied to the adjusting arm device.

[0012] - An adjustment device, which allows adjustment of the force that can be applied to the adjustment arm device by the at least one drive device, and

[0013] - A control device that enables control of the electric motor.

[0014] The control device has a determining device for determining a force that can be applied or has been applied to the adjusting arm device by the at least one drive device, and the at least one drive device has a damping device that can dampen the closing and / or opening movements of the adjusting arm device, wherein the determining device is configured to perform damper detection of the damping device.

[0015] Therefore, the assembler (or operator) no longer relies on themselves and must make the correct adjustments to the drive mechanism; instead, the furniture drive system itself assists the assembler (or operator) by detecting the forces acting on the adjustment arm device and thus on the movable furniture parts in the installed state. This allows for easy identification of whether the adjustments of the installed furniture drive system are matched to the furniture parts to be moved.

[0016] Preferred embodiments of the present invention are described throughout the specification.

[0017] The drive unit may have multiple components or parts that apply force to the adjusting arm device.

[0018] Preferably, the at least one drive device has a force storage unit, preferably in the form of a spring assembly, which acts on the carrier on one hand and, preferably indirectly, on the adjusting arm device on the other. Particularly preferably, the spring assembly has two separate pressure springs.

[0019] Preferably, the force storage device is configured to compensate for the weight of the adjusting arm device and the weight of the furniture components that can be connected to the adjusting arm device, and / or to move the adjusting arm device toward a fully closed position, and / or to move the adjusting arm device toward a fully open position. Therefore, the movable furniture components can be opened up to a certain angular position, in which the movable furniture components are then held in a balanced state by the adjusting arm device and the force storage device.

[0020] In addition to the force storage device, it is specified that the at least one drive device has a damping device that can dampen the closing and / or opening movements of the adjusting arm device. Therefore, smooth closing and opening can be achieved, and in particular, smooth arrival at the corresponding final position can be achieved.

[0021] Typically, it is preferred that the adjusting arm device be movable between a first maximum position and a second maximum position, the first maximum position corresponding to a closed position between the movable furniture component and the furniture body, and the second maximum position corresponding to the maximum open position of the movable furniture component relative to the furniture body.

[0022] In principle, it is possible for the damping device to dampen the entire movement path of the damping adjustment arm device. However, it is preferred that the damping is achieved by the damping device in the movement segment of the movable furniture part in the front closed position and the maximum open position.

[0023] Specifically, it can be specified that the (corresponding) forward movement section corresponds to the pivot angle range of the adjusting arm device (and thus indirectly the movable furniture component) between 2° and 25°, preferably between 5° and 15°.

[0024] As already described, the drive unit has two components, and the determining device can be used for both components: on the one hand, it can perform force storage detection on the force storage device, and on the other hand, it can perform damper detection on the damping device. It is possible that only one of these two detections is performed by the determining device. Preferably, the detection is performed by the determining device. When performing both detections, it is advantageous to perform the force storage detection first and then the damper detection.

[0025] For two specific and preferred determinations or detections, the following partially consistent preferred embodiments are provided.

[0026] Regarding the preferred specification of the force storage device, the determining device has a sensor for measuring the current consumption of the electric motor. Specifically, a resistance sensor can be used. The energy balance of the electric motor can also be detected.

[0027] Furthermore, it is preferably specified that, with the aid of the control device, the current consumption value of the electric motor measured by the sensor can be compared with a comparison value or comparison value change curve preferably determined and / or stored during reference driving, wherein a deviation signal can be output when the measured current consumption deviates from the comparison value or the comparison value change curve, preferably exceeding a determined threshold.

[0028] The comparison value could also be, for example, energy balance. The threshold could be percentage data; for example, a maximum deviation of 5% could be stored as the threshold.

[0029] The deviation signal can be output acoustically. Preferably, the control device can display a visual indicator signal on the furniture drive system, preferably on the cover, based on the output deviation signal. For example, a red LED can be illuminated as an indicator signal in a corresponding display panel.

[0030] Not only is the output deviation signal important, but the resulting effect is also important: specifically, it can be specified that when the output deviation signal is output, the force storage adjustment unit of the adjustment device can adjust the force acting on the adjustment arm device by the force storage.

[0031] For example, it can be specified that the force storage adjustment unit includes a rotatable adjustment wheel, wherein the force storage along the threaded spindle can be adjusted by the rotation of the adjustment wheel and thus the torque acting on the adjustment arm is adjustable.

[0032] Regarding the preferred specification of the damping device, the determining device has an angle sensor for measuring the angular position of the adjusting arm device.

[0033] Furthermore, it is preferred that, by means of the control device, the speed of the adjusting arm device can be determined by the values ​​measured from the angle sensor at different time points in the movement segment directly placed in the closed position and / or the open position.

[0034] According to a preferred embodiment, the control device enables the speed determined by the angle sensor to be compared with a preferred stored and / or a comparison value or comparison value change curve determined during reference driving. A deviation signal is output when the measured speed deviates from the comparison value or the comparison value change curve, preferably exceeding a predetermined threshold.

[0035] To prevent the force storage of the drive unit from affecting speed determination, it is preferably stipulated that, in this determination, the electric motor is preferably decoupled from the adjusting arm device by means of a freewheel clutch or is decoupled from it.

[0036] In damper testing, it is also preferred that the control device be able to display a visual indication signal on the furniture drive system, preferably on the cover, based on the output deviation signal.

[0037] Not only is the output deviation signal important, but the resulting outcome is also important: specifically, it can be specified that when the output deviation signal is output, the damping force and damping start position can be adjusted by the damper adjustment unit of the adjustment device, which are related to the angular position of the adjustment arm device relative to the carrier and / or the damping stroke.

[0038] For example, it can be specified that the relative position between the damper housing and the carrier can be adjusted between two positions by using the damper adjustment unit, preferably by switching a tool-free, switch-like adjustment device.

[0039] Typically, it is preferred that the adjusting arm device and the at least one drive device are part of a mechanical adjusting unit, and the electric motor is part of an electric drive unit, which is implemented as a structural unit separately constructed from the mechanical adjusting unit and has a drive member capable of being driven by the at least one electric motor for transmitting the torque of the electric motor to the adjusting arm device of the mechanical adjusting unit.

[0040] For motion transmission and motion switching, it can be specified that the electric drive unit has a transmission device between the electric motor and the drive component.

[0041] The transmission device is preferably specified to include at least two transmission stages, a freewheel clutch, and / or an overload clutch.

[0042] In the area of ​​the mechanical adjustment unit, motion transmission and motion switching are also advantageous, wherein, preferably, a transmission mechanism is provided, by which the force stored in the force storage device can be transmitted to the adjustment arm device.

[0043] In order to enable the locking and unlocking movements of the adjusting arm device, it is preferably specified that the transmission mechanism has a control cam and a pressure roller loaded by the force storage device, wherein the pressure roller is movable along the control cam when the at least one adjusting arm moves.

[0044] Furthermore, it is preferably specified that the adjusting arm device has a movablely supported adjusting component for transmitting force from the force storage device to the adjusting arm.

[0045] In order to connect or link the mechanical adjustment unit with the electric drive unit, it is preferably specified that the adjustment component has a transmission opening, into which a drive member that can be driven by the electric motor is inserted or can be inserted.

[0046] It also claims protection for a type of furniture having a main body, at least one furniture component that is movable, particularly about a horizontal axis, and a furniture drive system according to the invention, wherein the furniture component is in the form of an upwardly folding cover, an upwardly lifting cover, or an upwardly pivoting cover.

[0047] The aforementioned task is also solved by a method. Therefore, in the furniture drive system of the present invention, the following steps are provided: determining, by means of a determining device of a control device, a force that can be applied or has been applied to the adjusting arm device by the at least one drive device, wherein the determining device performs damper detection of the damping device.

[0048] The following steps are preferably specified for the detection of the above-mentioned force storage device:

[0049] - The current consumption of the electric motor is measured using sensors.

[0050] - Compare the measured current consumption with a comparison value or comparison value change curve preferably determined and / or stored during reference driving, and

[0051] - Output a deviation signal if the measured current consumption deviates from the comparison value or the curve showing the change of the comparison value, preferably exceeding a defined threshold.

[0052] In addition, it is preferable to set the following steps: when the output deviation signal is output, the force acting on the adjusting arm device by the force storage unit of the adjusting device is adjusted or set by the force storage unit of the adjusting device.

[0053] For the damper test described above (preferably to be performed after the force storage test), the following steps are preferably set up:

[0054] - Based on values ​​measured by an angle sensor at different time points, the speed of the adjusting arm device is determined within the movement segment directly preceding the closed position and / or the open position.

[0055] - The speed determined by the angle sensor is compared with a preferably stored comparison value or a comparison value change curve determined during reference driving, and

[0056] - Output a deviation signal if the measured speed deviates from the comparison value or the curve of change of the comparison value, preferably exceeding a determined threshold.

[0057] Finally, preferably, the following steps are also provided: when outputting a deviation signal, the damping force and damping start position are adjusted or set by the damper adjustment unit of the adjustment device, which are related to the angular position of the adjustment arm device relative to the carrier and / or the damping stroke of the damping device of the drive device.

[0058] In other words, the present invention can also be described as follows:

[0059] Force storage detection is performed via a reference travel in the form of opening and closing movements. Motor current is measured by a corresponding resistance sensor within a defined angular range, which is approximately midway between the closed and fully open positions (preferably between 20° and 90° between the final positions). If the values ​​at the open and closed positions are within a certain (balanced) range (threshold), the force storage regulation is correct and no deviation signal is output. Possible deviations are displayed on a monitor on the cover.

[0060] Damper testing is also performed via at least one reference drive. For this purpose, after the force accumulator test has successfully concluded to eliminate following errors, the angular position is detected by a magnetic angle sensor and compared with a reference time in the end regions of the opening and / or closing movements (where the force accumulator is decoupled from the adjusting arm to avoid working against the damper). If a deviation from the target value exists here, the damper must be adjusted to be stronger or weaker. This is also displayed accordingly on a display on the cover.

[0061] As a third variation, the determining device can also be used to check for rebound motion during (forced) closure or opening. For this purpose, the angular position of the oscillation is detected during the rebound motion and compared accordingly with a comparison value. When a rebound error signal is issued, the corresponding adjustment can also be changed. Attached Figure Description

[0080] Figure 1 The illustration shows a furniture 100 having a furniture body 3, wherein a furniture drive system 1 (furniture accessory) is fixedly attached to the side wall 3a of the furniture body 3 for moving a furniture component 2 that is movably supported.

[0081] In the illustrated embodiment, the movable furniture component 2 has two furniture covers 2a and 2b, wherein the first furniture cover 2a is pivotally connected to the furniture body 3 via at least two hinges 9a about a horizontally extending axis of rotation, and the second furniture cover 2b is pivotally connected to the first furniture cover 2a via at least two hinges 9b about a horizontally extending axis of rotation.

[0082] The furniture drive system 1 has a carrier 4 to be fastened to the furniture body 3, preferably to the side wall 3a of the furniture body 3, and at least one adjusting arm 52 pivotable relative to the carrier 4, the adjusting arm being connected to a movable furniture component 2, preferably to a second furniture cover 2b.

[0083] As you can see, Figure 1 The furniture 100 is arranged separately from the room ceiling 10. Figure 1 In the middle, the adjusting arm 52 has a relatively large pivot angle, which corresponds to the maximum open position OS of the movable furniture part 2.

[0084] Figure 2a A side view shows the mechanical adjustment unit 1.1 of the furniture drive system 1, wherein the mechanical adjustment unit 1.1 has a carrier 4 to be fastened to the furniture body 3 and at least one adjustment arm 52, the at least one adjustment arm being pivotally supported on the carrier 4 about a rotation axis X.

[0085] In the illustrated embodiment, an adjusting arm extension 11 is detachably arranged on an adjusting arm 52, wherein the adjusting arm extension 11 has two adjusting arm members 11a and 11b that are movable relative to each other. Preferably, the adjusting arm members 11a and 11b are telescopically movable relative to each other, wherein the first adjusting arm member 11a is detachably connected to the adjusting arm 52. The second adjusting arm member 11b has a fastening device 12, which is detachably connected to an accessory member to be fastened to a movable furniture part 2, preferably lockable and unlockable without tools.

[0086] To adjust the force loading of the adjusting arm 52 of the adjusting arm device 5, a force reservoir 6 is provided. This force reservoir may have at least one helical spring, preferably at least one compression spring. Alternatively, the force reservoir 6 may also have other force reservoirs, such as a fluid reservoir in the form of a pneumatic spring.

[0087] The adjusting arm device 5 has a transmission mechanism 51 for transmitting the force from the force storage 6 to the at least one adjusting arm 52. Preferably, the transmission mechanism 51 has a control cam 53 and a pressure roller 54 loaded by the force storage 6, wherein the pressure roller 54 is movable along the control cam 53 when the at least one adjusting arm 52 moves.

[0088] According to a preferred embodiment, the control cam 53 may be arranged or constructed on the adjusting arm 52. Alternatively, the control cam 53 may be arranged on other parts of the transmission mechanism 51 of the adjusting arm device 5.

[0089] exist Figure 2b In the case presented, the adjusting arm 52 and the adjusting member 55 are integrated for transmitting force from the force storage 6 to the adjusting arm 52. The control cam 53 is constructed on the adjusting member 55. Furthermore, a transmission opening 59 is constructed in the adjusting member 58, into which the drive member 31, which is driven by the electric motor 30, is engaged or can be engaged.

[0090] The force in the force storage 6 on at least one adjusting arm 52 can be adjusted via the force storage adjustment unit 14. Preferably,

[0091] - The force storage adjustment unit 14 has at least one rotatably supported adjustment wheel 14a, wherein the force exerted by the force storage 6 on at least one adjustment arm 52 can be adjusted by rotation of the adjustment wheel 14a, and / or

[0092] - The force storage adjustment unit 14 has at least one threaded spindle 16, and when the force storage adjustment unit 14 is operated, the actuating part 15 of the force storage 6 can move along the threaded spindle, and / or

[0093] - The carrier 4 has an end side with at least one opening 17a, through which at least one adjusting arm 52 protrudes in the open position, wherein the adjusting wheel 14a of the force storage adjusting unit 14 can be manipulated through the opening 17a from a direction transverse to the end side.

[0094] Figure 2b Shown in magnified view Figure 2a The area circled in the center. The transmission mechanism 51 has an intermediate rod 19, which is pivotally supported on the carrier 4 about a rotation axis 19a. A threaded spindle 16 is supported on the intermediate rod 19. The threaded spindle 16 is rotatable by rotating the adjusting wheel 14a of the force storage adjusting unit 14 with the aid of a tool, thereby moving the actuating part 15 of the force storage 6 along the threaded spindle 16. In this way, the relative distance between the actuating part 15 and the rotation axis 19a of the intermediate rod 19, and therefore the torque exerted by the force storage 6 on the adjusting arm 52, can be increased and decreased.

[0095] The mechanical adjustment unit 1.1 further includes at least one damping device 7 for damping the movement of at least one adjusting arm 52 of the damping adjustment arm assembly 5. The damping device 7, together with the force storage device 6, forms a drive device A by means of which force can be applied to the adjusting arm assembly 5.

[0096] Preferably, for the damping device 7, the damping device is specified as follows:

[0097] - Constructed as a fluid damper, and / or

[0098] - Having at least one piston-cylinder unit, and / or

[0099] - During the closing motion, it can be loaded via the at least one adjusting arm 52, and / or

[0100] - It is possible to load from the same side not only during the opening movement O of the at least one adjusting arm 52 but also during the closing movement S.

[0101] Figure 3a The mechanical adjustment unit 1.1 is shown in perspective, wherein the force of the force storage unit 6 can be transmitted to at least one adjustment arm 52 via the transmission mechanism 51 of the adjustment arm device 5. The force storage adjustment unit 14 may include, for example, a rotatable adjustment wheel 14a, wherein the actuating portion 15 of the force storage unit 6 along the threaded spindle 16 can be adjusted by the rotation of the adjustment wheel 14a, and thus the torque acting on the adjustment arm 52 is adjustable.

[0102] Furthermore, the mechanical adjustment unit 1.1 may have a mounting safety element 20 for an empty adjustment arm 52 (on which no movable furniture component 2 is yet installed) to limit the opening speed of the empty adjustment arm 52, wherein the mounting safety element 20 prevents the empty adjustment arm 52 from being unintentionally opened or moved due to the force of the force storage device 6. Preferably, the mounting safety element 20 includes at least one centrifugal clutch 20a.

[0103] Figure 3b The mechanical adjustment unit 1.1 is shown in a different (slightly offset) perspective view. The entire damping device 7 can be clearly seen in this figure. The damping device 7 has a damper housing 71 and a damper piston 72.

[0104] The damping device 7 can be adjusted relative to the carrier 4 via the damper adjustment unit 8. The damper adjustment unit 8 has an adjustment device 8a (in the form of a switch) and an adjustment pin 8x. The adjustment pin 8x is fixedly connected to the carrier 4.

[0105] exist Figure 3b In the middle, the adjusting device 8a pivots to the right, thereby placing the damping device 7 in the maximum position on the right relative to the carrier 4.

[0106] exist Figure 3b As can be seen, a first damping transmission element 5a is constructed on the adjusting arm 52. This first damping transmission element 5a is constructed in the form of a protrusion, which faces the damping device 7. Figure 3bIn the position presented, the stop 55 is spaced apart from the stop fitting 74 (still) constructed on the damper housing 71.

[0107] A stop element 56 (in the form of a roller) is arranged on the adjusting arm device 5. The stop element 56 is also spaced apart from the second damping transmission element 5b, which is pivotally supported on the carrier 4 by a pivot pin 57.

[0108] Figures 4a to 7b Vertical longitudinal sections passing through the mechanical adjustment unit 1.1 at different locations are shown.

[0109] exist Figure 4a and 4b In the middle, the adjusting arm device 5 is located in the same open position. This corresponds to the movable furniture part 2 being approximately half-open. The opening angle of the adjusting arm 52 is all within the range of 55° to 80°.

[0110] However Figure 4a and Figure 4b The difference lies in the location of the damping device 7. Figure 4b In the middle, the damping device 7 is located in its maximum position on the right. As in... Figure 5b As can be seen in the enlarged view, the adjusting device 8a rotates to the right about the adjusting pin 8x. Therefore, the relatively wide area of ​​the adjusting device 8a is located between the damper housing 71 and the adjusting pin 8x.

[0111] On the contrary, Figure 4a and its belonging Figure 5a In this configuration, the adjusting device 8a of the damper adjusting unit 8 rotates 90° to the left. Therefore, the relatively narrow area of ​​the adjusting device 8a lies between the damper housing 71 and the adjusting shaft pin 8x. The damping device 7 is located in its maximum position on the left.

[0112] According to Figures 4a to 5b In all positions, the damping device 7 is unloaded and therefore relaxed and in the fully disengaged position. The second pressure transmission element 5b rests against the damping piston 72.

[0113] exist Figure 5a and 5b The comparison shows that the damper housing 71 performs a (slight) pivoting motion relative to the carrier 4, in addition to the translational displacement motion relative to the carrier 4.

[0114] exist Figure 6a and 6b In the middle, from the previous Figures 4a to 5bThe mechanism initiates the opening movement O of the adjusting arm device 5. This causes the adjusting arm 52 to pivot upwards. The opening movement O is executed until the stop 55 of the first damping transmission element 5a contacts the stop engagement 74. In this position, the damping start position D is reached.

[0115] Because the damping device 7 is in Figure 6a and 6b Since the damping starts at different maximum positions, the adjusting arm 52 occupies different angular positions in the given damping start position D. Specifically, in Figure 6a The opening angle is given as approximately 108°, while... Figure 6b The opening angle is given as 100°.

[0116] If the opening movement O continues from the corresponding damping start position D, the damper piston 72 is pushed into the damper housing 71 by the stop engagement 74, thereby enabling the damping device 7 to function. Once the damper piston 72 is fully engaged, the maximum opening position OS (not shown) is reached.

[0117] Therefore, the movement section of the movable furniture component 2, positioned at its maximum open position OS, is damped, wherein the damping start position D is adjusted differently by the damper adjustment unit 8. This allows for adjustment to different opening angles to initiate the damped movement.

[0118] The same principle also applies to closed motion S.

[0119] exist Figure 7a and 7b From Figures 4a to 5b The adjusting arm 52 initiates a closed movement S, thereby pivoting downwards. This closed movement S continues until the stop element 56 contacts the second damping transmission element 5b due to the rotational movement of the adjusting arm 52 around the rotation axis X. The damping initiation position D is reached at this position.

[0120] Because the damping device 7 is in Figure 7a and 7b Since the damping starts at different maximum positions, the adjusting arm 52 occupies different angular positions in the given damping start position D. Specifically, in Figure 7a The opening angle is given as approximately 22°, while... Figure 7b The opening angle is given as almost 33°.

[0121] As the closing motion S continues from the corresponding damping start position D, the second damping transmission element 5b rotates counterclockwise around the shaft pin 57 via the stop element 56. This causes the damping transmission element 5b to press against the damper piston 72 via the stop 58, pushing the damper piston into the damper housing 71, thus enabling the damping device 7 to function again. Once the damper piston 72 is fully engaged, the closed position SS (not shown) is reached.

[0122] exist Figure 8 The entire furniture 100 is shown in a perspective view. In this view, the power supply unit 21 can be seen, through which energy can be supplied to the electric drive unit 1.2 (not visible here).

[0123] In addition, Figure 8 In this system, detection devices 22 are provided on both sides of the main body 3 of the furniture. These detection devices are used to detect overpressure movements and / or to trigger a closing movement S. When the movable furniture part 2 is in the closed position SS and the user presses on the movable furniture part 2, this is detected by the detection device 22, which then triggers the opening movement O of the furniture drive system 1 via the control device 44 and the electric drive unit 1.2. Figure 8 In the movable furniture component 2 that is opened, the user can directly press on one of the detection devices 22, which then triggers the closing movement S of the furniture drive system 1 via the control device 44 and the electric drive unit 1.2.
