Description

[Technical field]

[0001] The invention relates to an electric motor-driven furniture drive comprising at least one electric motor, at least one interface, preferably detachably connectable between the electric motor-driven furniture drive and a mechanical actuator, and at least one identification device for automatically identifying the configuration of the mechanical actuator. The invention further relates to a furniture drive system for movable furniture parts, in particular for furniture flaps in the form of furniture flap-type, fold-up flaps, swivel-up flaps or lift-up flaps, comprising such an electric motor-driven furniture drive and a mechanical actuator. The invention further relates to furniture comprising such a furniture drive system and to a method for operating the furniture drive system.

[0002] Furniture drive systems with adjustable arm devices have been used for decades to move furniture flaps that are rotatable or pivotable around a horizontal axis or slidable along a vertical plane. Examples of such furniture fittings can be taken from WO 2012 / 155165 and WO 2011 / 020130.

[0003] Furthermore, furniture drive systems are known which have two separate components, namely a mechanical actuator (including an energy accumulator) and an electric motor-driven furniture drive, examples of which can be taken from EP 3 443 191 A1 and AU 519 935 A1.

[0004] What is important about such furniture drive systems is that the same system can be used in the same way for movable furniture parts of different sizes and weights. For this purpose, individual parameters (e.g. forces) of the drive (including energy storage and, if necessary, damping devices) and / or the electric motor can be set via a setting device.

[0005] In conventional furniture drive systems, the action obtained from the drive may not be adapted to the movable furniture part being driven, which may often result in damage to the movable furniture part or even in accidents with the person operating the movable furniture part.

[0006] In order to prevent erroneous input of operating parameters, an electric motor-driven furniture flap drive is known from EP 2315897, which has a discrimination device for automatically discriminating the furniture flap type of the furniture flap drive from the possible furniture flap types: fold-up flap, swivel-up flap and lift-up flap. The discrimination device is connected to a distance measuring device, by means of which the distance that the adjusting arm can travel between its two end positions can be determined, and by means of which the flap type is discerned depending on the measurement result of the distance measuring device.

[0007] The disadvantage of this prior art is that for identification, the entire furniture flap drive must be assembled and the movement of the adjustment arm must already have taken place, so that if the components or parts do not fit together, undesired movements that are damaging or dangerous for the user can occur already during the inspection or identification movement.

[0008] The object of the present invention is therefore to avoid these problems, and in particular to make the identification of configurations easier.

[0009] This problem is solved by an electric motor-driven furniture drive having the features of claim 1.

[0010] Thus, according to the invention, at least one identification device is arranged in at least one area at at least one interface of the electric motor-driven furniture drive, so that the configuration of the mechanical actuator can be identified when the electric motor-driven furniture drive is coupled to the mechanical actuator, such that the coupling is already sufficient for a successful identification, without the need to perform any movement of the furniture drive components.

[0011] Preferred embodiments of the invention are set out in the dependent claims and throughout the description.

[0012] According to a preferred embodiment, a control device is provided that can control the electric motor. The control device is preferably designed to be integrated into the housing of the electric motor-driven furniture drive. For example, the control device can have a printed circuit board, a microprocessor arranged thereon, and further circuit elements, if necessary.

[0013] Further preferably, the controller, preferably the memory device, is arranged to store a number of data sets for different configurations of the mechanical actuator.

[0014] The identification device can use various sensors, by means of which the parameters of the mechanical actuator can be detected, for example for tactile identification pressure-sensitive mats, contact springs, microprobes, magnetic proximity sensors, magnetic angle sensors or capacitive angle sensors.

[0015] Particularly preferably, the identification device is capable of matching the parameters detected by the sensor with the data set, the actual configuration of the mechanical actuator is capable of being identified, and a control signal can be output to the electric motor via the control device depending on the actual configuration of the mechanical actuator identified via the identification device.

[0016] These control signals can then be used to enable output of operating parameters appropriate for the configuration upon actuation, i.e. the electric motor can be driven and controlled to match the mechanical actuator.

[0017] The interface should be configured such that a secure but releasable coupling between the electric motor-driven furniture drive and the mechanical actuator is easily possible. Particularly preferably, the interface is configured to have a substantially flat coupling plate (preferably oriented along a vertical plane in the mounted state) and coupling elements arranged on the coupling plate for releasably coupling the electric motor-driven furniture drive with a coupling counterpart formed on the mechanical actuator.

[0018] For a specific embodiment of the identification device, there is the option to perform the identification of the configuration via an RFID or wireless module.

[0019] Particularly preferably, the identification device is configured to have at least one mechanical probe element pivotally supported on the at least one interface.

[0020] With at least one pivotable probe element, a large number of different configurations and / or parameters (e.g., in interaction with a corresponding probe element counterpart such as a probe surface) can be coded with a compact and small number of component components (e.g., via a pivotable slider that translates or represents a number of specific configurations and / or parameters by associated (e.g., equally spaced) areas of the pivotable probe element and / or probe element counterpart).

[0021] However, for a simpler and less cumbersome embodiment, the identification device has at least one mechanical probe element which abuts against at least one probe element-counterpart of the mechanical actuator, which represents a parameter of the mechanical actuator (when the coupling between the electric motor driven furniture drive and the mechanical actuator is obtained via an interface).

[0022] In order to enable reliable and meaningful identification via this mechanical probe element, it is preferably configured that at least one mechanical probe element is movably, preferably rotatably or slidably, supported on at least one interface.

[0023] According to a first variant embodiment, the probe element is configured such that the pivotally supported probe element is pivotable about a pivot axis (preferably oriented perpendicular to the vertical plane) and the pivotally supported probe element has a probe face facing away from the interface and inclined relative to the pivot axis, preferably at an angle of between 30° and 60°.

[0024] Preferably, the tilted probe surface is further configured to have a probe line on the probe surface extending from the pivot axis that is closest to the interface, and a probe line on the probe surface extending from the pivot axis that is furthest from the interface.

[0025] Furthermore, the probe line closest to the interface and the probe line farthest from the interface are configured to be spaced apart from each other by 180° with the rotation axis as the origin.

[0026] Between these two probe lines is a surface that is substantially elliptical when viewed from above, which is slidable along the probe element counterpart.

[0027] In order to ensure reliable identification even in the case of incorrect assembly of the furniture drive and the actuator, it is particularly preferred that the probe line furthest from the interface is also configured to form a probe projection which can enter the probe element counterpart.

[0028] Patent protection is also claimed for a furniture drive system for movable furniture parts, in particular for furniture flaps in the form of furniture flap-type, fold-up flaps or swivel-up flaps or lift-up flaps, comprising an electric motor-driven furniture drive and a mechanical actuator according to the invention.

[0029] The mechanical actuator of the furniture drive system preferably has the following main components: a support for assembling the furniture drive system to the furniture cabinet; - an adjustable arm device movably, preferably pivotably, supported on a support and which can be coupled to a movable furniture part, the electric motor The adjustment arm device is coupled or coupleable to the adjustment arm device, and the adjustment arm device is at least partially movable via an electric motor, and the mechanical actuator further comprises: - It has a force accumulator, preferably in the form of a spring assembly, which acts on the support on the one hand and, preferably indirectly, on the adjustment arm arrangement on the other hand.

[0030] It is further preferred that the electric motor-driven furniture drive is implemented as a modular unit formed separately from the mechanical actuator and which can be coupled or is coupled via an interface.

[0031] In order to enable the movement transmission between the structural units, the electric motor-driven furniture drive is preferably configured to have a driver that can be driven by at least one electric motor in order to transmit the torque of the electric motor to the adjustment arm device of the mechanical actuator.

[0032] Regarding the configuration of the mechanical actuators, there are various characteristics that are important for the operation. Two particularly important characteristics are the furniture flap type and the power factor of the energy store. For example, if there are three different configurations of each, then a total of nine different combinations are obtained.

[0033] Accordingly, the configuration of the mechanical actuators can preferably be configured to be selected from the group of actuators for fold-up flaps of the furniture flap type, actuators for pivot-up flaps of the furniture flap type and actuators for lift-up flaps of the furniture flap type. Additionally (or alternatively), the configuration of the mechanical actuators can be configured to be selected from the group of mechanical actuators that are substantially identical in structure and preferably differ from each other only in the power factor of the energy accumulator.

[0034] With regard to the power factor, it can be mentioned, for example, that there are power accumulators with large power, power accumulators with average power, and power accumulators with small power.

[0035] Furniture flap types include the following: For example, there are furniture flaps known as upper flaps, where the flap is fixed to the underside of the cabinet cover by means of a hinge.

[0036] Furthermore, there is a flap consisting of two parts, a first partial flap is connected to the furniture cabinet by a pivot joint and a second partial flap is connected to the first partial flap by a pivot joint, when the flap is moved to the open position, the first partial flap is pivoted upwards and away from the furniture cabinet and the second partial flap is likewise pivoted upwards and towards the furniture cabinet, so that the flap is folded in the open position (upward folding flap).

[0037] In a pivot-up flap, the flap is pivoted rearward over the furniture cabinet.

[0038] If the flap performs a movement approximately parallel to the front surface of the furniture cabinet, preferably during its entire opening or closing process, it is called an upwardly lifting flap.

[0039] These terminologies are to be maintained within the scope of the present invention, and it should be understood that the enumeration of different furniture flap types (and therefore power factors and other identifiable actuator parameters, as appropriate) is not exhaustive.

[0040] Preferably, the force accumulator is configured to compensate for the gravity of the adjustable arm device and the furniture part connectable thereto and / or to move the adjustable arm device in the direction of a fully closed position and / or to move the adjustable arm device in the direction of a fully open position, so that the movable furniture part can be opened up to a certain angular position in which the movable furniture part remains balanced by the adjustable arm device and the force accumulator.

[0041] In addition to the force accumulator, the mechanical actuator can be configured to have a damping device by means of which the closing and / or opening movement of the adjustment arm arrangement can be damped, thereby allowing smooth closing and opening and in particular a gentle reaching of the respective end positions.

[0042] Typically and preferably, the adjustable arm arrangement is configured to be movable between a first maximum position corresponding to a closed position between the moveable furniture part and the furniture cabinet, and a second maximum position corresponding to a maximum open position of the moveable furniture part relative to the furniture cabinet.

[0043] Basically, the damping device can damp the entire travel path of the adjustable arm arrangement, but it is preferably provided that damping is provided via the damping device in the travel section of the movable furniture part which is located before the closed position and the maximum opening position.

[0044] In particular, the (respectively) forwardly located moving section may be configured to correspond to a swivel angle range of the adjustable arm device (and thus of the indirectly movable furniture part) of 2° to 25°, preferably 5° to 15°.

[0045] For the purpose of the movement transmission and movement conversion in the electric motor-driven furniture drive, a transmission can be provided between the electric motor and the driver.

[0046] The transmission is preferably configured to include at least two transmission stages, a freewheel clutch and / or an overload clutch.

[0047] Also in the area of ​​mechanical actuators, movement transmission and movement transformation are advantageous, and preferably a transmission mechanism is provided, which can transmit the force of the force accumulator to the adjustment arm device.

[0048] In order to enable the adjustment arm device to be moved to close and to open, the transmission mechanism preferably has a control cam and a pressure roller biased by a force accumulator, the pressure roller being configured to be able to run along the control cam when the at least one adjustment arm is moved.

[0049] Preferably, the adjustment arm arrangement is further configured to have a movably supported actuator part for transmitting a force from the force accumulator to the adjustment arm.

[0050] In order to couple or connect a mechanical actuator with an electric motor-driven furniture drive, the actuator part is preferably configured to have a transmission opening in which a follower that can be driven by the electric motor engages or is engageable.

[0051] Patent protection is also claimed for a piece of furniture comprising a furniture cabinet and at least one furniture part movable, in particular around a horizontal axis, in particular in the form of an upward folding flap, an upward lifting flap or an upward pivoting flap, and a furniture drive system according to the invention.

[0052] The above-mentioned problem is also solved by a method according to claim 19. Thus, in a furniture drive system, the invention comprises the steps of coupling an electric motor-driven furniture drive and a mechanical actuator via at least one interface, and automatically identifying the configuration of the mechanical actuator via an identification device when coupling the electric motor-driven furniture drive and the mechanical actuator via at least one interface.

[0053] For the above mentioned identification, the following steps are preferably provided: - detecting a parameter of a mechanical actuator via a sensor of an identification device; - matching the parameters detected by the sensor with stored data sets for different configurations of the mechanical actuator; - identifying an actual configuration of the mechanical actuator based on the stored data set; - outputting a control signal to the electric motor depending on the actual configuration of the mechanical actuator identified via the identification device.

[0054] In part, the invention can be further described as follows: The overall problem is type identification in a furniture drive system comprising a mechanical actuator and an electric motor-driven furniture drive. The furniture flap type is identified already during assembly (i.e. coupling) of the electric motor-driven furniture drive to the mechanical actuator. It is also identified which furniture flap type (i.e. fold-up flap, swivel-up flap or lift-up flap) and which energy storage and power factor there are. Each furniture flap type, power factor and combination corresponds to one configuration.

[0055] The identification of the configuration affects many operating parameters of the furniture drive system, namely: -Opening angle -Operation profile -Forward angle calculation -Reference Run -Identification of whether components are correctly assembled - Energy storage unit error identification - Statistical evaluation (e.g. in the event of a claim) - Support for assembly workers, Affects.

[0056] According to a preferred variant, the probe element is configured such that the slidably supported probe element has at least two separate probe pins protruding from the interface (preferably perpendicular to the vertical plane). If two probe pins are provided, this allows four different configurations to be detected in binary values. With three probe pins, eight different configurations can be detected correspondingly.

[0057] Preferably, the slidably supported probe element, preferably a probe pin, can be brought into contact with a conductor path, which is configured to include at least one, preferably two, and / or radially shaped conductor path contours for determining a parameter of the mechanical actuator.

[0058] In this context, radial is to be understood as meaning that web-like conductor track contour segments project laterally from the conductor track contour. Particularly preferably, the webs of the conductor track contour are arranged side by side in some regions.

[0059] Preferably, the slidably supported probe element, preferably a probe pin, is configured to include a first spring, preferably located within the probe pin in at least a portion of the area, and / or a second spring, preferably located outside the probe pin, for determining a parameter of the mechanical actuator.

[0060] The first spring can support the restoring action of the probe element via the second spring and, in a dual-function sense, can form an electrical contact connection with the conductor track.

[0061] Preferably, the first spring is galvanically isolated from the probe pin and / or is configured such that it can make contact with a conductor track, preferably with at least two conductor track contours.

[0062] In the case of a galvanic separation between the first spring and the probe pin, the probe pin can be made, for example, from plastic or a metallic material can be provided for the probe pin. By means of the first spring, an electrical contact can be created between two spatially separate regions of the two conductor track contours, so that an identification of a parameter of the mechanical actuator can be determined.

[0063] The first spring serves the multiple functions of restoring force increase, electrical connection to the conductor track and possible formation of the probe pin in the form of plastic.

[0064] Preferably, the mechanical actuator is determinable via a combination of at least one parameter determined via the identification device and the opening angle of the mechanical actuator, which can preferably be determined by a reference run of the furniture drive system.

[0065] This extends the functionality of the identification device through the additional information of the opening angle of the mechanical actuator.

[0066] Preferably, the slidably supported probe element is configured to have at least one probe pin protruding from the interface (preferably perpendicular to the vertical plane), and preferably the slidably supported probe element is configured to be positionable on an optionally provided conductor path and / or to be positioned on a mechanical actuator for contact connection of a predetermined area of ​​an optionally provided conductor path.

[0067] By contact connection of a probe element or probe pin at a predetermined position along the conductor path, the parameters of the mechanical actuator can be determined, and the conductor path (e.g. with a probe pin arranged on the mechanical actuator) may be arranged in a conductor path area specific to the mechanical actuator.

[0070] FIG. 1 shows a piece of furniture 100 comprising a furniture cabinet 3, in which a furniture drive system 1 (furniture fitting) for moving a movably supported furniture part 2 is fixed to a side wall 3a of the furniture cabinet 3.

[0071] In the illustrated embodiment, the movable furniture part 2 has two furniture flaps 2a, 2b, a first furniture flap 2a is pivotally connected to the furniture cabinet 3 via at least two hinges 9a about a horizontally extending pivot axis and a second furniture flap 2b is pivotally connected to the first furniture flap 2a via at least two hinges 9b about a horizontally extending pivot axis.

[0072] The furniture drive system 1 comprises a support 4 to be fixed to a furniture cabinet 3, preferably to a side wall 3a of the furniture cabinet 3, and at least one adjustment arm 52 pivotable relative to the support 4, which adjustment arm 52 is connected to a movable furniture part 2, preferably to a second furniture flap 2b.

[0073] As can be seen, the furniture 100 in Fig. 1 is positioned at a distance relative to the ceiling 10. In Fig. 1, the adjustment arm 52 has taken up a relatively large swivel angle, which corresponds to the maximum open position OS of the movable furniture part 2.

[0074] FIG. 2a shows a side view of a mechanical actuator 1.1 of a furniture drive system 1, which has a support 4 to be fixed to a furniture cabinet 3 and at least one adjusting arm 52 supported on the support 4 so as to be pivotable about a rotation axis X.

[0075] In the embodiment shown, the adjustable arm extension 11 is removably arranged on the adjustable arm 52, the adjustable arm extension 11 having two adjustable arm parts 11a, 11b which are slidable relative to one another. Preferably, the adjustable arm parts 11a, 11b are slidable telescopically relative to one another, and the first adjustable arm part 11a and the adjustable arm 52 are configured to be removably connectable. The second adjustable arm part 11b has a fastening device 12 which is removably connectable to a fitting part to be fixed to the movable furniture part 2 and which is preferably lockable and unlockable without tools.

[0076] For applying a force to the adjusting arm 52 of the adjusting arm arrangement 5, a force accumulator 6 is provided, which may for example comprise at least one coil spring, preferably at least one compression spring. Alternatively, the force accumulator 6 may comprise another force accumulator, for example a fluid force accumulator in the form of a gas compression spring.

[0077] The adjustment arm device 5 has a transmission mechanism 51 for transmitting the force of the force accumulator 6 to the at least one adjustment arm 52. Preferably, the transmission mechanism 51 has a control cam 53 and a pressure roller 54 biased by the force accumulator 6, and is configured such that the pressure roller 54 can run along the control cam 53 when the at least one adjustment arm 52 moves.

[0078] The control cam 53 may be arranged or formed in the adjustment arm 52 according to a preferred embodiment. Naturally, it is also possible to arrange the control cam 53 at another point in the transmission mechanism 51 of the adjustment arm arrangement 5.

[0079] In the case shown in Fig. 2b, the adjusting arm 52 is formed in one piece with an actuator part 58 for transmitting the force from the force accumulator 6 to the adjusting arm 52. The control cam 53 is formed in this actuator part 58. Furthermore, a transmission opening 59 is formed in this actuator part 58, in which a driver 31 which can be driven by an electric motor 30 engages or can engage.

[0080] The force of the force accumulator 6 acting on the at least one adjustment arm 52 can be set by means of the force accumulator setting unit 14. It is preferably configured as follows: the force accumulator-setting unit 14 has at least one pivotally supported setting wheel 14a, and the force of the force accumulator 6 acting on the at least one adjusting arm 52 can be set by pivoting the setting wheel 14a, and / or the energy accumulator and setting unit 14 has at least one threaded spindle 16 along which the application point 15 of the energy accumulator 6 is movable during operation of the energy accumulator and setting unit 14, and / or The support 4 has an end face with at least one opening 17a, through which at least one adjusting arm 52 projects in the open position, and a setting gear 14a of the energy accumulator-setting unit 14 can be operated laterally to the end face and through the opening 17a.

[0081] In Fig. 2b, the area circled in Fig. 2a is shown in an enlarged view. The transmission mechanism 51 has an intermediate lever 19, which is supported on the support 4 so as to be pivotable about a pivot axis 19a. A threaded spindle 16 is supported on the intermediate lever 19. By rotating the setting gear 14a of the energy accumulator-setting unit 14 with a tool, the threaded spindle 16 can be rotated, whereby the action point 15 of the energy accumulator 6 is moved along the threaded spindle 16. In this way, the relative distance between the action point 15 and the pivot axis 19a of the intermediate lever 19, and thus the torque of the energy accumulator 6 acting on the adjustment arm 52, can be increased and decreased.

[0082] The mechanical actuator 1.1 further comprises at least one damping device 7 for damping the movement of at least one adjustment arm 52 of the adjustment arm arrangement 5. This damping device 7 together with the force accumulator 6 forms a drive A by means of which a force can be exerted on the adjustment arm arrangement 5.

[0083] Preferably, for the damping device 7, this is - configured as a fluid damper; and / or -has at least one piston-cylinder unit; and / or - can be actuated by at least one adjustment arm 52 during the closing movement; and / or At least one adjustment arm 52 is configured so that it can be biased from the same side during both the opening movement O and the closing movement S.

[0084] In Fig. 3a the mechanical actuator 1.1 is shown in a perspective view, in which the force of the force accumulator 6 can be transmitted to at least one adjusting arm 52 by means of a transmission mechanism 51 of the adjusting arm arrangement 5. The force accumulator and setting unit 14 can, for example, comprise a rotatable setting gear 14a, in which the application point 15 of the force accumulator 6 can be set along the threaded spindle 16 by means of the rotation of the setting gear 14a and thus by means of a torque acting on the adjusting arm 52.

[0085] The mechanical actuator 1.1 may furthermore comprise an assembly lock 20 for the unassembled adjusting arm 52, i.e. for an adjusting arm 52 to which a movable furniture part 2 has not yet been assembled, which makes it possible to limit the opening speed of the unassembled adjusting arm 52 and which prevents unintentional opening or sudden jumping out of the unassembled adjusting arm 52 due to the force of the force accumulator 6. It is preferably configured such that the assembly lock 20 comprises at least one centrifugal clutch 20a.

[0086] 3b shows another (slightly offset) perspective view of the mechanical actuator 1.1. In this view, the entire damping device 7 is clearly visible. This damping device 7 comprises a damper housing 71 and a damper piston 72.

[0087] Via an attenuator setting unit 8, the attenuation device 7 is positionable relative to the support 4. The attenuator setting unit 8 has a setting means 8a (in the form of a switch) and a setting pin 8x. The setting pin 8x is fixedly connected to the support 4.

[0088] In FIG. 3 b the setting means 8 a has been tilted to the right, whereby the damping device 7 is in its maximum right position relative to the support 4 .

[0089] It can be seen in Fig. 3b that a first damping transmission element 5a is formed on the adjustment arm 52. This first damping transmission element 5a is made in the form of a protrusion pointing towards the damping device 7. In the position shown in Fig. 3b, the stop 55 is (still) spaced apart from a stop counter-element 74 formed on the damper housing 71.

[0090] A stop element 56 (in the form of a roller) is arranged on the adjusting arm device 5. This stop element 56 is (still) spaced apart from the second damping transmission element 5b, which is pivotably supported on the support 4 via an axle pin 57.

[0091] 4a to 7b show vertical longitudinal cross-sections of the mechanical actuator 1.1 in different positions, one after the other.

[0092] In Figure 4a and Figure 4b the adjustable arm device 5 is in the same open position. This corresponds to an approximately half-open movable furniture part 2. The opening angle of the adjustable arm 52 is somewhere in the range of 55° to 80°.

[0093] However, Figures 4a and 4b differ in that the damping device 7 is in a different position. In Figure 4b the damping device 7 is in its maximum position to the right. As can be seen from the associated enlarged view according to Figure 5b, the setting means 8a has been pivoted to the right about the setting pin 8x. This results in a relatively wide region of the setting means 8a being located between the damper housing 71 and the setting pin 8x.

[0094] In contrast to this, in Fig. 4a and in the associated Fig. 5a the setting means 8a of the attenuator setting unit 8 has been rotated by 90° to the left, so that a relatively narrow area of ​​the setting means 8a is located between the attenuator housing 71 and the setting axle pin 8x. The damping device 7 is in its maximum position to the left.

[0095] 4a to 5b the damping device 7 is unloaded and thus in a relaxed and extended position. The second pressure transmission element 5b abuts against the damper piston 72.

[0096] Comparing FIGS. 5 a and 5 b it can be seen that in addition to the translational sliding movement relative to the support 4 the damper housing 71 also undergoes a (slight) pivoting movement relative to the support 4 .

[0097] In Figures 6a and 6b (starting from the previous Figures 4a to 5b) an opening movement O of the adjusting arm device 5 is performed. The adjusting arm 52 is thereby pivoted upwards. This opening movement O is performed until the stopper 55 of the first damper transmission element 5a comes into contact with the stopper corresponding member 74. In this position, the damping start position D, respectively, is reached.

[0098] Since the damping device 7 is in different maximum positions in Figures 6a and 6b, the adjustment arm 52 assumes different angular positions at the respectively shown damping start position D. In particular, in Figure 6a an opening angle of approximately 108° is shown, whereas in Figure 6b an opening angle of 100° is shown.

[0099] As the opening movement O continues from the respective damping start position D, the damper piston 72 is pushed into the damper housing 71 via the stopper corresponding member 74, thereby causing the damping device 7 to exert its action. As soon as the damper piston 72 is fully inserted, the maximum opening position OS is reached (not shown).

[0100] Thereby, a travel section of the movable furniture part 2 which is located before the maximum opening position OS is damped, whereby the damping start position D is set differently via the damper and setting unit 8. Thereby, different opening angles for the start of the damping travel can be set.

[0101] The same principle applies to the closing move S.

[0102] In Figures 7a and 7b (starting from Figures 4a to 5b) a closing movement S of the adjusting arm arrangement 5 is taking place, whereby the adjusting arm 52 is pivoted downwards. This closing movement S is taken place until the stop element 56 comes into contact with the second damping transmission element 5b due to the pivoting movement of the adjusting arm 52 about the pivot axis X. In this position the damping start position D, respectively, is reached.

[0103] Since the damping device 7 is in different maximum positions in Figures 7a and 7b, the adjustment arm 52 assumes different angular positions at the respectively shown damping start position D. In particular, in Figure 7a an opening angle of approximately 22° is shown, whereas in Figure 7b an opening angle of just 33° is shown.

[0104] If the closing movement S is continued from this respective damping start position D, the second damping transmission element 5b pivots counterclockwise about the pivot pin 57 via the stop element 56, so that the damping transmission element 5b presses the damper piston 72 via the stop 55 and forces it into the damper housing 71, whereby the damping device 7 also exerts its effect. As soon as the damper piston 72 has fully advanced, the closed position SS is reached (not shown).

[0105] 8 shows the entire furniture 100 in a perspective view, where the power supply unit 21 can be seen, via which the electric motor-driven furniture drive 1.2 (not visible here) can be supplied with energy.

[0106] Fig. 8 further shows detection devices 22 on both sides of the furniture cabinet 3 for detecting an overpressure movement and / or for triggering 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 devices 22, which results in an opening movement O of the furniture drive system 1 being initiated via the control device 44 and the electric motor-driven furniture drive 1.2. With the movable furniture part 2 as open in Fig. 8, the user can directly press on one of the detection devices 22, which results in an opening movement S of the furniture drive system 1 being initiated via the control device 44 and the electric motor-driven furniture drive 1.2.

[0107] 9 shows in a perspective view only the furniture cabinet 3 with the furniture drive systems 1 arranged on both sides of the furniture cabinet 3. The protective front 23 of the electric motor-driven furniture drive 1.2 is clearly visible.

[0108] In Fig. 10, a furniture drive system 1 with a mechanical actuator 1.1 and an electric motor-driven furniture drive 1.2 is shown in a perspective view. The two units 1.1 and 1.2 are laterally removably connected to each other via their respective housings. Via a support 4, the entire furniture drive system 1 can be fixed to a furniture cabinet 3. The electric motor-driven furniture drive 1.2 has a protective front plate 23.

[0109] 11 also shows the furniture drive system 1 in a perspective view, but without the protective front panel 23, which allows an unobstructed view of the cover 24 which together form the housing of the electric motor-driven furniture drive 1.2. On the cover 24 of the furniture drive system 1, a visual indicator signal H can be displayed.

[0110] In Fig. 12, the electric motor-driven furniture drive 1.2 and the mechanical actuator 1.1 are shown separated. The housing of the mechanical actuator 1.1 is formed with a (curved) engagement opening 25, via which the actuator part 58 of the adjustment arm device 5 can be engaged.

[0111] Correspondingly, in FIG. 13, which shows the furniture drive system 1 from a different perspective, the follower 31 can be seen protruding from the (curved) outlet opening 26 in the housing of the electric motor-driven furniture drive 1.2.

[0112] This face of the electric motor-driven furniture drive 1.2 facing the mechanical actuator 1.1 forms an interface 90, via which the two drives 1.1 and 1.2 can be removably coupled to one another. From this interface 90, which is oriented along a vertical plane, a part of the identification device 91 (in particular a mechanical probe element 96) protrudes in the direction of the mechanical actuator 1.1.

[0113] As can be seen in FIG. 13, the interface 90 includes a coupling plate 93 and a number of coupling elements 94 (which together form a housing).

[0114] 12, there can be seen mating members 95 which correspond to the mating elements 94. These mating members 95 are formed in or on the housing of the mechanical actuator 1.1. The mating elements 94 are releasably matable to the mating members 95 by a snap-fit, slip-on, clip-fit ​​or the like.

[0115] In FIG. 14, only the housing of the electric motor-driven furniture drive 1.2 is shown together with the cover 24.

[0116] In Fig. 15, the electric motor-driven furniture drive 1.2 is shown on the side facing the mechanical actuator 1.1. The follower 31 is configured as a pin in the illustrated embodiment, which is supported in a limited sliding manner in a guide contour (outlet opening 26) formed in the housing. The follower 31 protrudes from the housing on the side facing the mechanical actuator 1.1.

[0117] In FIG. 15 the coupling plate 93 and coupling elements 94 as well as the mechanical probe elements 96 of the identification device 91 are again particularly visible.

[0118] In FIG. 16 the electric motor-driven actuator 1.2 of the furniture drive system 1 is shown in a perspective detailed view, with the part of the cover 24 facing the mechanical actuator 1.1 omitted.

[0119] The electric motor-driven furniture drive 1.2 comprises an electric motor 30 for electric motor-driven support of the movement of a movable furniture part 2 which can be fastened to an adjustment arm 52. Furthermore, the electric motor-driven furniture drive 1.2 comprises a follower 31 which can be (indirectly) driven by the electric motor 30, by means of which the torque of the electric motor 30 is transmitted to the mechanical actuator 1.1 or to the adjustment arm 52 and, if necessary, to the furniture part 2 which is connected to the adjustment arm 52.

[0120] The mechanical actuator 1.1 and the electric motor-driven furniture drive 1.2 are removably connectable to each other, so that the electric motor-driven furniture drive 1.2 can be easily connected to or disconnected from the mechanical actuator 1.1.

[0121] The components of the electric motor-driven furniture drive 1.2 can be arranged in a housing which, as shown, comprises a cover 24. The housing abuts the mechanical actuator 1.1 at least in certain areas and, in the example shown, separates the latter from the components of the electric motor-driven furniture drive 1.2.

[0122] Instead of a housing, for example, a mounting plate can also be used which does not surround the component units of the electric motor-driven furniture drive 1.2 but rather defines and supports them only on one side.

[0123] Between the electric motor 30 and the driving body 31, a transmission 32 is provided for converting the torque of the electric motor 30 into a rotational movement of the driving body 31 around a rotation axis 33. The transmission 32 has a plurality of transmission stages (a worm 40 and gears 34, 35, 36, 37, 38 and 39). The transmission stages 34 to 40 are engaged with each other through meshing. The transmission 32 further includes a freewheel clutch 41 incorporated in the gear 36 and an overload clutch 42 incorporated in the gear 39.

[0124] The electric motor-driven furniture drive 1.2 also has a dedicated damping device 43 for damping the movement of the follower 31 around the pivot axis 33.

[0125] Returning to FIG. 1, the following will be explained in more detail.

[0126] The electric motor-driven furniture drive 1.2 comprises an identification device 91 which itself comprises a sensor 92 and a mechanical probe element 96 which is arranged in the region of the interface 90 with the mechanical actuator 1.1 which itself comprises a probe element counterpart 97 which corresponds to the mechanical probe element 96 (shown diagrammatically).

[0127] When coupling the electric motor-driven furniture drive 1.2 with the mechanical actuator 1.1, a configuration K of the mechanical actuator 1.1 can be identified. In particular, the mechanical probe element 96 is contact-connected to a probe element counterpart 97 during coupling. The probe element counterpart 97 represents a parameter P of the mechanical actuator 1.1. Due to the contact connection, the mechanical probe element 96 is displaced, whereby the position of the probe element 96 can be detected by the sensor 92.

[0128] The parameters P of the mechanical actuator 1.1 detected by the sensor 92 are transmitted to the control device 44. The control device 44 stores a data set F which contains several configurations K of the mechanical actuator 1.1 (as illustrated in FIG. 1). In particular, eight different configurations K are obtained, which consist of three furniture flap types HF, HS and HL and three power factors L of the energy accumulator 6.

[0129] The identification device 91 then performs a check of the parameters P detected by the sensor 92 with the data set F via the control device 44 to determine the actual configuration K of the mechanical actuator 1.1. akt is identified.

[0130] Then, again via the control device 44, the actual configuration K of the mechanical actuator 1.1, identified via the identification device 91, is akt A control signal I can be output to the electric motor 30 depending on

[0131] Figure 17 shows the details of the identification device 91. In particular, it can be seen in Figure 17 a probe element 96 that is pivotally supported on the housing (preferably on a coupling plate 93 of the interface 90, not shown here) that is pivotable about a pivot axis T (preferably oriented perpendicular to the vertical plane) and that has a probe face B facing the mechanical actuator 1.1 and inclined relative to the pivot axis.

[0132] 17, the tilted probe surface B has a probe line B1 located on the probe surface B that extends radially from the pivot axis T and is closest to the interface, and a probe line B2 located on the probe surface B that extends radially from the pivot axis T and is furthest from the interface. The probe line B2 that is furthest from the interface also forms a probe protrusion N that can enter the probe element counterpart 97.

[0133] In the variant according to Fig. 17, the rotatable mechanical probe is coupled via two gears (not shown here) to the sensor 92. Other movement transmission variants are also possible.

[0134] 18 shows a cross-section of the electric motor-driven furniture drive 1.2 in the region of the electric motor 30 and of the mechanical probe element 96, where the probe plane B and the probe projection N are clearly visible. The mechanical probe element 96 is spring-supported along a pivot axis T. The pivotal movement or the pivotal position of this mechanical probe element 96 can be detected via the sensor 92.

[0135] The perspective view according to FIG. 19 makes the inclined probe surface B and the shape of the mechanical probe element 96 with the probe projection N particularly visible.

[0136] In Fig. 20 (unlike Fig. 19) the housing of the electric motor-driven furniture drive 1.2 is also shown. A mechanical probe element 96 protrudes from this housing through an opening in the coupling plate 93.

[0137] 21 shows a perspective view of a housing part 89 of the mechanical actuator 1.1 facing the interface 90. In this housing part 89, a probe element counterpart 97 is formed.

[0138] FIG. 22 shows the probe element counterpart 97 in detail, and the probe element counterpart 97 is configured as an embossed portion formed on the housing thin plate.

[0139] Figure 23 shows the probe element counterpart 97 before coupling and the mechanical probe element 96 facing but still spaced apart. In Figure 24 there is still a small distance between them, whereas in Figure 25 the two parts 96, 97 are coupled and the probe element 96 has pivoted about a pivot axis T according to the shape of the probe element counterpart 97. The coupling element 94 and the coupling counterpart 95 are likewise coupled to each other.

[0140] FIG. 26 shows housing portion 89 in plan view with embossed probe element counterpart 97.

[0141] In figure 27 a detail of figure 26 is shown. The probe element counterpart 97 has a recess into which the probe projection N can enter during coupling. The probe element counterpart 97 has a projection 99 which projects into the recess and by means of which the parameter P of the mechanical actuator 1.1 is defined or represented. That is to say, already during the production of the housing part 89 of the mechanical actuator 1.1, the probe element counterpart 97 is produced or embossed for subsequent identification during coupling with the electric motor-driven furniture drive 1.2.

[0142] 28 and 29, the protrusions 99 are offset. Thus, the probe element counterpart 97 represents a different parameter P.

[0143] Further, the type identification can be explained based on Fig. 30. Starting from the starting position (vertically facing up), a dead zone of 10° is located on either side of this starting line. Then, (analogous to a clock) there are 12 regions (=340°) each with about 28.3°. Each of these regions corresponds to a parameter P from which the configuration K itself can be identified. That is, depending on how the protrusions 99 are embossed, the configuration K can be identified via the identification device 91.

[0144] In other words, the mechanical probe element 96 is oriented in an embossment in the housing sheet (probe element counterpart 97). The bending of the probe element 96 is detected and evaluated by the electronics of the control unit 44.

[0145] 31-42 show another embodiment having alternative embodiments of mechanical probe elements 96 and probe element counterparts 97. FIG.

[0146] In Fig. 31 a furniture drive system is shown in a perspective view, which includes a mechanical actuator 1.1 and an electric motor-driven furniture drive 1.2. A protective front plate 23 is additionally shown. In the housing part 89 of the mechanical actuator 1.1, a probe element counter member 97 in the form of three openings is formed.

[0147] FIG. 32 is identical to FIG. 31 with the area of ​​the probe element counterpart 97 circled.

[0148] This circled area is shown enlarged in figure 33. It can thus be seen that in this case the two openings on the right side of the probe element counterpart 97 are open, whereas the one on the left is blocked, i.e. these three openings form a kind of code representing the parameter P of the mechanical actuator 1.1.

[0149] In Fig. 34 the furniture drive system 1 is shown from another perspective, which allows a partially unobstructed view of the interface 90 of the electric motor-driven furniture drive 1.2. The mechanical probe element 96 is already visible in the circled area.

[0150] The circled area is shown enlarged in Figure 35. It can be seen that the mechanical probe element 96 has three slidably supported probe pins 98 which protrude through the binding plate 93.

[0151] In Fig. 36, the housing part 89 of the mechanical actuator 1.1 is shown in a perspective view, the rest being hidden. Only the electric motor-driven furniture drive 1.2, in particular the mechanical probe element 96, is shown in the circled area, the remaining components of the electric motor-driven furniture drive 1.2 being hidden for better visibility.

[0152] Figure 37 shows an enlarged view of the circled area of ​​Figure 36. Each individual probe pin 98 is surrounded by a compression spring 88 and is preloaded via the respective compression spring 88 towards the housing part 89.

[0153] FIG. 38 again shows housing portion 89 from another perspective, along with mechanical probe element 96.

[0154] 39, it can be seen that the left opening of the probe element counterpart 97 is blocked, thereby retaining the probe pin 98 of the mechanical probe element 96. In contrast, the two probe pins 98 on the right side enter the two open openings of the probe element counterpart 97.

[0155] These different positions of the probe pin 98 are detectable by the sensor 92 .

[0156] In FIG. 40, a housing portion 89 with the probe pin cut in half is shown in a perspective view.

[0157] The circled area in Figure 40 is shown enlarged in Figure 41. It can be seen that the two probe pins 98 on the right go into the openings in the probe element counterpart 97, while the probe pin 98 on the left remains in a protrusion 99 that blocks the opening.

[0158] FIG. 42 shows a top view of the three probe pins 98, where it can be clearly seen that two of the probe pins 98 pass through the housing part 89 in the area of ​​the openings of the probe element counterpart 97.

[0159] Overall, the variants shown in Figures 31 to 42 with three probe pins 98 result in nine possible variants of the parameter P of the mechanical actuator 1.1 (depending on how many and which openings of the probe element / counterpart 97 are blocked).

[0160] If the mechanical probe element 96 has, for example, only two slidably supported probe pins 98 (not shown), then only a maximum of four parameters P and configurations K identifiable therefrom can be identified and distinguished.

[0161] Similarly, with four slidably supported probe pins 98 (not shown), 16 different configurations K are obtained, and so on.

[0162] 43a shows an embodiment of another structure of mechanical probe elements 96 including probe pins 98. The slidably supported probe elements 96 (of which there can generally be any number) can be brought into contact with conductor tracks 103 (shown in an enlarged detailed partial view below the mechanical actuator 1.1), which include two radially shaped conductor track contours 104 for determining a parameter P of the mechanical actuator 1.1.

[0163] In FIG. 43b it can be seen that the slidably supported probe element 96 (including the probe pin 98) includes a first spring 101 arranged within the probe pin 98 in some areas and a second spring 102 arranged outside the probe pin 98 in some areas to determine a parameter P of the mechanical actuator 1.1.

[0164] The first spring 101 is galvanically separated from the probe pin 98 in the form of plastic or metal and can be brought into contact with two conductor track contours 104 of a conductor track 103 .

[0165] In Fig. 44a, an electric motor-driven furniture drive 1.2 is shown connected to a mechanical actuator 1.1, which can be determined via a combination of a parameter P determined via the identification device 91 (as is generally possible in all embodiments) and an opening angle of the mechanical actuator 1.1, which opening angle can be determined by a reference run of the furniture drive system 1 (e.g. by a maximum tilt angle or by a specific angle between two end positions of the mechanical actuator 1.1). To identify this mechanical actuator 1.1, a probe element-counterpart 97 acts as a counter-receiver, whereby a first spring 101 comes into contact with a conductor track 103 (two conductor track contours 104).

[0166] In general, the slidably supported probe element 96 can have exactly one or several separate probe pins 98 protruding from the interface 90 at right angles to the vertical plane, the slidably supported probe element 96 being positionable on the conductor track 103 and, if necessary, on the mechanical actuator 1.1 for contact connection of a predetermined area of ​​the conductor track 103 (preferably, the mechanical probe element 96 is arranged in the housing part 89). This allows the identification of the mechanical actuator 1.1 via the predetermined positioning of the probe pins 98 with a small number of mechanical probe elements 96.

[0167] In Fig. 44b, in order to distinguish this mechanical actuator 1.1, the probe element counterpart 97 does not function as a counterpart receiver, whereby the first spring 101 is spaced apart and thus not in contact with the conductor track 103. Constructional details of the slidably supported mechanical probe element 96 (such as e.g. the protrusions 99) (see Fig. 41) can be used alternatively or additionally in this embodiment of the mechanical probe element 96.

[0168] Finally, two further variants (not shown) are mentioned:

[0169] It can be arranged that via the identification device 91 only the configuration K for the power factor L can be identified. For the identification of the furniture flap types HF, HS and HL a distance measuring device can be provided (for example as described in EP 2 315 891 B1) by means of which the distance that the adjusting arm can travel between its two end positions can be determined and depending on the measurement result of this distance measuring device the furniture flap type can be identified. There is therefore a mixed variant embodiment between the identification according to the invention during coupling and the identification of the configuration by the adjustment arm movement.

[0170] Up to this point, the mechanical probe element 96 has always been described as a protruding component. However, it is also perfectly possible for the mechanical probe element 96 to be formed as a recess and for the probe element counter-part 97 to be formed as a corresponding counter-part, with the same basic principle being applied for the identification in the mechanical inversion.
