Description

Electromotive furniture drive

The present invention relates to an electromotive furniture drive with at least one electric motor, at least one interface via which the electromotive furniture drive can be connected, preferably detachably, to a mechanical actuator, and at least one identification device for automatically identifying a configuration of the mechanical actuator. In addition, the invention relates to a furniture drive system for a movable furniture part, in particular for a furniture flap in the form of a furniture flap type fold-up flap, swing-up flap or lift-up flap, with such an electromotive furniture drive and a mechanical actuator. Furthermore, the invention relates to a piece of furniture with such a furniture drive system and a method for operating the furniture drive system.

Furniture drive systems with actuator arm devices have been used for many decades to move furniture flaps that can be rotated or pivoted about a horizontal axis or that are displaceable along a vertical plane. Examples of such furniture fittings can be found in WO 2012/155165 A2 and WO 2011/020130 A1.

In addition, furniture drive systems are known in which these systems have two structural units that are separate from one another, namely a mechanical actuating drive (including an energy store) and an electromotive furniture drive. Examples of this can be found in EP 3443 191 B1 and AT 519935 A1.

With such furniture drive systems, it is important that the same systems can be used in the same way for furniture parts of different sizes and weights that can be moved. For this purpose, individual parameters (e.g. force) can be set using the setting devices. the drive device (comprising the force accumulator and optionally a damping device) and/or the electric motor.

With previous furniture drive systems, it can happen that the effect emanating from the drive device does not match the driven movable furniture part. In some cases, this can lead to damage to the movable furniture part or even to accidents involving a person operating the movable furniture part.

In order to prevent incorrect input of operating parameters, an electromotive furniture flap drive is known from EP 2315 897 B1, which has an identification device for automatically identifying the furniture flap type of the furniture flap drive from the possible furniture flap types of fold-up flap, swing-up flap and lift-up flap. This identification device is connected to a path measuring device, by means of which the path that can be covered by the actuating arm between its two end positions can be determined, with the identification device identifying the flap type as a function of the measurement result of the path measuring device.

The disadvantage of this prior art is that the entire furniture flap drive has to be assembled for the identification and the actuating arm has to be moved. It can therefore happen that in the case of non-matching units or components, damage or undesired movements that are dangerous for a user can already occur during the testing or identification movement.

The object of the present invention is therefore to avoid these problems. In particular, the identification of the configuration should be simplified. This is solved by an electromotive furniture drive with the features of claim 1.

Accordingly, the invention provides that the at least one identification device is arranged at least in regions on the at least one interface of the electromotive furniture drive, so that the configuration of the mechanical actuator can be identified when the electromotive furniture drive is connected to the mechanical actuator. Thus, just connecting is enough to carry out the identification successfully. The furniture drive components do not have to move.

Preferred embodiments of the present invention are set forth in the dependent claims and throughout the specification.

According to a preferred exemplary embodiment, a control device is provided with which the electric motor can be controlled. Provision is preferably made for this control device to be integrated into a housing of the electromotive furniture drive. For example, this control device can have a printed circuit board and a microprocessor arranged thereon, as well as optionally further switching elements.

Furthermore, it is preferably provided that several data sets for different configurations of the mechanical actuator are stored in the control device, preferably in a memory.

Various sensors can be used for the identification device, via which a parameter of the mechanical Actuator can be detected. For example, safety mats, contact springs, micro-keys, magnetic proximity sensors, magnetic angle sensors or capacitive angle sensors can be used for tactile detection.

Provision is particularly preferably made for the identification device to be able to compare the parameter recorded by the sensor with the data sets and to identify the current configuration of the mechanical actuator, with control signals being sent via the control device depending on the current configuration of the mechanical actuator identified via the identification device to the Electric motor can be issued.

These control signals can then be used to be able to output operating parameters that match the configuration during operation. The electric motor can therefore be controlled to match the mechanical actuator.

The interface should be designed in such a way that a secure but nevertheless detachable connection between the electromotive furniture drive and the mechanical actuator is possible in a simple manner. Provision is particularly preferably made for the interface to have a substantially planar connecting plate—preferably aligned along a vertical plane in the installed state—and connecting elements arranged on the connecting plate for detachably connecting the electromotive furniture drive to mating connecting pieces formed on the mechanical actuator.

For the specific configuration of the identification device, there is the possibility that the configuration is detected via RFID modules or radio modules. Provision is particularly preferably made for the identification device to have at least one mechanical feeler element which is rotatably mounted on the at least one interface.

With at least one rotatable probe element - for example in interaction with a corresponding probe element counterpart such as a scanning surface - a large number of different configurations and/or parameters can be set compactly and with a small number of structural components (e.g. via a rotary slide, which has a large number of specific configurations and/or parameters translated or represented by these associated—particularly equidistantly arranged—areas of the rotatable probe element and/or the probe element counterpart).

For a simpler and less complex configuration, however, it is provided that the identification device has at least one mechanical probe element which—when there is a connection via the interface between the electromotive furniture drive and the mechanical actuator—on at least one probe element representing a parameter of the mechanical actuator. counterpart of the mechanical actuator.

In order to enable reliable and meaningful identification via this mechanical feeler element, it is preferably provided that the at least one mechanical feeler element is movably, preferably rotatably or displaceably mounted on the at least one interface.

According to a first variant, it is provided for the probe element that the rotatably mounted probe element can be rotated about an axis of rotation—preferably aligned at right angles to the vertical plane is, wherein the rotatably mounted probe element has a remote from the interface, relative to the axis of rotation, preferably at an angle between 30 ° and 60 °, inclined scanning surface.

Furthermore, it is preferably provided that the inclined scanning surface has a scanning line lying on the scanning surface, leading away from the axis of rotation, closest to the interface and a scanning line lying on the scanning surface, leading away from the axis of rotation and furthest from the interface.

In addition, it is provided that the scanning line closest to the interface and the scanning line furthest from the interface are spaced apart from one another by 180°, starting from the axis of rotation.

Between these two scanning lines there is a surface which is essentially oval in a plan view and which can slide along the scanning element counterpart.

For reliable identification even when the furniture drive and the actuator are assembled imprecisely, it is particularly preferred that the scanning line furthest from the interface also forms a scanning nose that can be moved into the scanning element counterpart.

Protection is also sought for a furniture drive system for a movable furniture part, in particular for a furniture flap in the form of a furniture flap type fold-up flap, swing-up flap or lift-up flap, with an electromotive furniture drive according to the invention and a mechanical actuator.

The mechanical actuator of the furniture drive system preferably has the following essential components:

- a carrier for mounting the furniture drive system on a furniture body, - A movable, preferably rotatable, mounted actuating arm device on the carrier, which can be connected to the movable furniture part, wherein the electric motor is connected to the

The actuating arm device is connected or can be connected and via which the actuating arm device can be moved at least in sections, and

at least one energy accumulator, preferably in the form of a spring assembly, acting on the one hand on the carrier and on the other hand, preferably indirectly, on the actuating arm device.

Furthermore, it is preferably provided that the electromotive furniture drive is designed as a structural unit which is designed separately from the mechanical actuator and which can be or are connected to one another via the interface.

In order to enable movement transmission between the structural units, it is preferably provided that the electromotive furniture drive has a driver, which can be driven by the at least one electric motor, for transmitting a torque of the electric motor to the actuating arm device of the mechanical actuating drive.

With regard to the configuration of the mechanical actuator, there are several characteristics that are essential for its operation. Two particularly important properties are the type of furniture flap and the power factor of the energy store. For example, if there are three different configurations each, there are a total of nine different combinations.

Accordingly, it can preferably be provided that the configuration of the mechanical actuator is selected from the group actuator for the furniture flap type fold-up flap, actuator for the furniture flap type flip-up flap and actuator in front of the furniture flap type high-lift flap. In addition (or alternatively) it can be provided that the configuration of the mechanical actuator is selected from a group of mechanical actuators which are essentially structurally identical and differ from one another, preferably only by a power factor of the energy accumulator.

With regard to the power factor, it can be stated that, for example, there are energy accumulators with a high force, with a medium force and with a low force.

The following is listed for the types of furniture flaps:

For example, there are furniture flaps that have become known as lift-up flaps, in which the flap is attached to the underside of the cabinet lid by means of hinges.

There are also two-part flaps, with a first partial flap being pivotally connected to the furniture body and a second partial flap being pivotally connected to the first partial flap. When moving the flap into the open position, the first partial flap is pivoted upwards away from the furniture body, with the second partial flap also being pivoted upwards towards the furniture body, so that the flap is folded together in the open position (fold-up flap).

In the case of swing-up flaps, the flap is pivoted backwards over the furniture body.

If the flap preferably performs a movement essentially parallel to the front side of the furniture body during its entire opening or closing path, this is referred to as a lift-up flap. This terminology should also be retained within the scope of the present invention, with the enumeration of the different types of furniture flaps (and also the performance factors and possibly other identifiable actuator parameters) not being understood to be exhaustive.

It is preferably provided that the force accumulator is designed to compensate for a weight of the actuating arm device and the furniture part that can be connected to the actuating arm device and/or to move the actuating arm device in the direction of a fully closed position and/or to move the actuating arm device in the direction of a fully open position to move. The movable furniture part can thus be opened up to a certain angular position, in which the movable furniture part then remains in a state tared by the actuating arm device and the force accumulator.

In addition to the force accumulator, it can be provided that the mechanical actuating drive has a damping device with which a closing movement and/or an opening movement of the actuating arm device can be damped. This enables smooth closing and opening and, above all, gentle reaching of the respective end position.

In general, it is preferably provided that the actuating arm device can be moved between a first maximum position, which corresponds to the closed position between the movable furniture part and the furniture body, and a second maximum position, which corresponds to the maximum open position of the movable furniture part relative to the furniture body.

In principle, it is possible for the damping device to dampen the entire movement path of the actuating arm device. However, it is preferably provided that the damping is carried out via the damping device takes place in a movement section of the movable furniture part upstream of the closed position and the maximum open position.

Specifically, it can be provided that the (respectively) upstream movement section corresponds to a pivoting angle range of the actuating arm device (and thus indirectly of the movable furniture part) of between 2° and 25°, preferably between 5° and 15°.

A transmission can be provided between the electric motor and the driver for movement transmission and conversion within the electromotive furniture drive.

It is preferably provided for this gear that it comprises at least two gear stages, an overrunning clutch and/or an overload clutch.

Transmission and conversion of movement is also advantageous in the area of the mechanical actuating drive, a transmission mechanism preferably being provided with which the force of the energy store can be transmitted to the actuating arm device.

In order to enable a tightening and opening movement of the actuating arm device, it is preferably provided that the transmission mechanism has a control cam and a pressure roller loaded by the force accumulator, the pressure roller being movable along the control curve when the at least one actuating arm moves.

Furthermore, it is preferably provided that the actuating arm device has a movably mounted actuating part for the transmission of a force from the force accumulator to the actuating arm. In order to connect or link the mechanical actuating drive to the electromotive furniture drive, it is preferably provided that the actuating part has a transmission opening into which the driver, which can be driven by the electric motor, engages or can engage.

Protection is also sought for a piece of furniture with a furniture body, at least one furniture part that can be moved, in particular about a horizontal axis, in particular in the form of a fold-up flap, lift-up flap or pivot-up flap, and a furniture drive system according to the invention.

The above object is also achieved by a method according to claim 19. Accordingly, in a furniture drive system, the invention provides for connecting the electromotive furniture drive to the mechanical actuator via the at least one interface and automatically identifying a configuration of the mechanical actuator via the identification device when connecting the electromotive furniture drive to the mechanical actuator via the at least one interface.

The following steps are preferably provided for said identification:

- detecting a parameter of the mechanical actuator via a sensor of the identification device,

- Comparison of the parameters recorded by the sensor with stored data sets for different configurations of the mechanical actuator,

- Identification of the current configuration of the mechanical actuator using the stored data sets and

- Outputting a control signal to the electric motor in

Dependence on the identification device identified, current configuration of the mechanical actuator.

In partially different words, the present invention can also be described as follows:

Overall, it is a matter of identifying a type in a furniture drive system comprising a mechanical actuating drive and an electromotive furniture drive. The furniture flap type is already recognized when the electromotive furniture drive is installed (i.e. when it is connected) to the mechanical actuator. It is recognized both what type of furniture flap - i.e. fold-up, swing-up or lift-up flap - and what the energy storage power factor is. Each furniture flap type-power factor combination corresponds to a configuration.

The detection of the configuration has an impact on many operating parameters of the furniture drive system:

- opening angle

- Motion Profile

- Front angle calculation

- Reference run

- Detection of whether the structural units are assembled correctly

- Force storage error detection

- Statistical analysis (e.g. in the event of a complaint)

- Assistance for the fitter

According to a preferred variant, it is provided for the feeler element that the displaceably mounted feeler element has at least two separate feeler pins protruding from the interface—preferably at right angles to the vertical plane. If there are two styluses, four different configurations can be detected in binary. At three There are eight different detectable configurations corresponding to the stylus.

It is preferably provided that the displaceably mounted probe element, preferably a probe pin, can be brought into contact with a conductor track, the conductor track comprising at least one, preferably two and/or star-shaped conductor track contours for determining a parameter of the mechanical actuator.

Star-shaped is to be interpreted in this context in such a way that web-like conductor track contour segments project transversely from the conductor track contour. The webs of the conductor track contours are particularly preferably arranged next to one another in certain areas.

It is preferably provided that the displaceably mounted probe element, preferably a tracer pin, comprises a first spring, preferably arranged at least in regions within the tracer pin, for determining a parameter of the mechanical actuator and/or a second spring, preferably arranged on the outside of the tracer pin.

A restoring effect of the probe element can be supported by the first spring via the second spring and, in the sense of a dual function, can produce electrical contact with the conductor track.

Provision is preferably made for the first spring to be electrically isolated from the stylus and/or to be able to be brought into contact with the conductor track, preferably with at least two conductor track contours.

If there is a galvanic isolation between the first spring and the stylus, the stylus can be off, for example Be plastic, with metallic materials can be provided for the stylus. The first spring can be used to generate an electrical contact between two spatially separate areas of the two conductor track contours, as a result of which an identification of parameters of the mechanical actuator can be determined.

The first spring allows a multiple function of increasing the restoring force, the electrical connection to the conductor track and the possible design of the tracer pin in the form of plastic to be used.

It is preferably provided that the mechanical actuator can be determined via a combination of at least one parameter determined via the identification device and an opening angle of the mechanical actuator, which can preferably be determined by a reference run of the furniture drive system.

As a result, the functionality of the identification device is expanded via the additional information on an opening angle of the mechanical actuator.

Provision is preferably made for the displaceably mounted probe element to have at least one tracer pin protruding from the interface—preferably at right angles to the vertical plane. It is preferably provided that the displaceably mounted probe element can be arranged on a conductor track that may be present and/or on the mechanical actuator for contacting a defined area of the conductor track that may be present is arranged.

Contacting the probe element or the probe pin at a defined position along the interconnect can be a parameter of the mechanical actuating drive can be determined, the conductor track--for example when the scanning pin is arranged on the mechanical actuating drive--can be arranged on a region of the conductor track that is specific to the mechanical actuating drive.

1 shows a piece of furniture 100 with a furniture body 3, a furniture drive system 1 (furniture fitting) for moving a movably mounted furniture part 2 being fastened to a side wall 3a of the furniture body 3.

In the exemplary embodiment shown, the movable furniture part 2 has two furniture flaps 2a, 2b, with a first furniture flap 2a being pivotable about a horizontal axis of rotation with the furniture body 3 via at least two hinges 9a and the second furniture flap 2b being pivotable about a horizontal axis of rotation via at least two hinges 9b is pivotally connected to the first furniture flap 2a.

The furniture drive system 1 has a carrier 4 to be fastened to the furniture carcass 3, preferably to the side wall 3a of the furniture carcass 3, and at least one actuating arm 52 which can be pivoted relative to the carrier 4 and which is connected to the movable furniture part 2, preferably to the second furniture flap 2b .

It can be seen that the piece of furniture 100 in FIG. 1 is arranged at a distance from the ceiling 10 of the room. In FIG. 1, the actuating arm 52 assumes a relatively large pivoting angle, which corresponds to the maximum open position OS of the movable furniture part 2.

2a shows the mechanical actuator 1.1 of the furniture drive system 1 in a side view, the mechanical actuator 1.1 having a carrier 4 to be fastened to the furniture body 3 and at least one actuating arm 52, which is pivotably mounted on the carrier 4 about an axis of rotation X. In the exemplary embodiment shown, an actuating arm extension 11 is detachably arranged on the actuating arm 52, the actuating arm extension 11 having two actuating arm parts 11a, 11b which can be displaced relative to one another. Provision is preferably made for the actuating arm parts 11a, 11b to be telescopically displaceable relative to one another, with the first actuating arm part 11a being detachably connectable to the actuating arm 52. The second actuating arm part 11b has a fastening device 12, which can be releasably connected to a fitting part to be fastened to the movable furniture part 2, preferably locked and unlocked without tools.

For the application of force to the actuating arm 52 of the actuating arm device 5, a force accumulator 6 is provided which, for example, can have at least one helical spring, preferably at least one compression spring. Alternatively, the energy accumulator 6 can also have other energy accumulators, such as a fluid accumulator in the form of a gas pressure spring.

The actuating arm device 5 has a transmission mechanism 51 for transmitting a force from the force accumulator 6 to the at least one actuating arm 52 . Provision is preferably made for the transmission mechanism 51 to have a cam 53 and a pressure roller 54 loaded by the energy store 6, with the pressure roller 54 being movable along the cam 53 when the at least one actuating arm 52 moves.

According to a preferred exemplary embodiment, the cam 53 can be arranged or formed on the actuating arm 52 . It is of course also possible to arrange the control cam 53 at a different point in the transmission mechanism 51 of the actuating arm device 5 . In the case shown in FIG. 2 b , the actuating arm 52 is in one piece with an actuating part 55 for transmitting a force from the energy accumulator 6 to the actuating arm 52 . The cam 53 is formed on this adjusting part 55 . In addition, the transmission opening 59 is formed in this actuating part 58, in which the driver 31, which can be driven by the electric motor 30, engages or can engage

A force of the force accumulator 6 on the at least one actuating arm 52 can be adjusted by means of an energy accumulator adjustment unit 14 . It is preferably provided that

- The force accumulator adjustment unit 14 has at least one rotatably mounted adjustment wheel 14a, wherein a force of the energy accumulator 6 acting on the at least one adjustment arm 52 can be adjusted on the adjustment arm 52 by rotating the adjustment wheel 14a, and/or

- The force accumulator setting unit 14 at least one

Has threaded spindle 16, along which a point of application 15 of the force accumulator 6 is movable upon actuation of the force accumulator setting unit 14 and/or

- The carrier 4 has an end face with at least one opening 17a, through which the at least one actuating arm 52 protrudes in an open position, with a dial 14a of the

Force accumulator adjustment unit 14 can be actuated from a direction transverse to the end face through the opening 17a.

FIG. 2b shows the circled area in FIG. 2a in an enlarged view. The transmission mechanism 51 has an intermediate lever 19 which is mounted on the carrier 4 so that it can pivot about an axis of rotation 19a. The threaded spindle 16 is mounted on the intermediate lever 19. By rotating the adjustment wheel 14a of the force accumulator adjustment unit 14 using a tool, the threaded spindle 16 can be rotated, whereby the

Point of attack 15 of the force accumulator 6 along the threaded spindle 16 moves. In this way, the relative distance between the point of application 15 and the axis of rotation 19a of the intermediate lever 19 and thus the torque of the force accumulator 6 acting on the actuating arm 52 can be increased or decreased.

The mechanical actuating drive 1.1 also includes at least one damping device 7 for damping a movement of the at least one actuating arm 52 of the actuating arm device 5. This damping device 7 together with the force accumulator 6 forms the drive device A, with which a force can be exerted on the actuating arm device 5.

It is preferably provided for the damping device 7 that it

- Is designed as a fluid damper and / or

- Has at least one piston-cylinder unit and/or

- Can be acted upon by the at least one actuating arm 52 during a closing movement and/or

- Can be acted upon from the same side both during an opening movement 0 and during a closing movement S of the at least one actuating arm 52 .

3a shows the mechanical actuating drive 1.1 in a perspective view, with a force of the force accumulator 6 being able to be transmitted to the at least one actuating arm 52 by the transmission mechanism 51 of the actuating arm device 5. FIG. The force accumulator adjustment unit 14 can, for example, comprise a rotatable adjustment wheel 14a, the point of application 15 of the force accumulator 6 being adjustable along the threaded spindle 16 by rotating the adjustment wheel 14a and thus the torque acting on the adjustment arm 52.

The mechanical actuator 1.1 can also have an assembly lock 20 for the empty actuating arm 52, on which no movable furniture part 2 has been mounted, to limit a Have opening speed of the empty actuator arm 52, wherein the assembly lock 20 prevents unintentional opening or deflection of the empty actuator arm 52 by a force of the force accumulator 6. It is preferably provided that the assembly lock 20 comprises at least one centrifugal clutch 20a.

3b shows a further (slightly offset) perspective view of the mechanical actuator 1.1. The entire damping device 7 can be clearly seen in this illustration. This damping device 7 has the damper housing 71 and the damper piston 72 .

The damping device 7 can be adjusted relative to the carrier 4 via the damper adjustment unit 8 . The damper adjustment unit 8 has the adjustment means 8a (in the form of a switch) and the adjustment pivot 8x. The adjusting axle pin 8x is firmly connected to the carrier 4.

In FIG. 3b, the adjustment means 8a is pivoted to the right, as a result of which the damping device 7 is in a right-hand maximum position relative to the carrier 4.

It can be seen in FIG. 3b that a first damping transmission element 5a is formed on the actuating arm 52 . This first damping transmission element 5a is designed in the form of an extension which faces the damping device 7 . In the position shown in Fig. 3b, the stop 55 is (still) at a distance from the counterpart stop 74 formed on the damper housing 71.

A stop element 56 (in the form of a roller) is arranged on the actuating arm device 5 . This stop element 56 is (still) at a distance from the second damping transmission element 5b, which is pivotably mounted on the carrier 4 via the axle pin 57. 4a to 7b each show a vertical longitudinal section through the mechanical actuator 1.1. in different positions.

In FIGS. 4a and 4b the actuating 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 actuating arm 52 is somewhere in the range between 55° and 80°.

However, FIGS. 4a and 4b differ in that the damping device 7 is in different positions. In Fig. 4b, the damping device 7 is in its right maximum position. As can be seen in the associated enlarged representation according to FIG. 5b, the adjustment means 8a is rotated to the right about the adjustment pivot pin 8x. As a result, there is a relatively wide area of the adjustment means 8a between the damper housing 71 and the adjustment pivot 8x.

In contrast, in FIG. 4a and in the associated FIG. 5a, the adjustment means 8a of the damper adjustment unit 8 is rotated 90° to the left. As a result, there is a relatively narrow area of the adjustment means 8a between the damper housing 71 and the adjustment pivot pin 8x. The damping device 7 is in its left maximum position.

In all positions according to FIGS. 4a to 5b, the damping device 7 is unloaded and thus relaxed and in the fully extended position. The second pressure transmission element 5b is in contact with the damping piston 72 .

In a comparison between Fig. 5a and 5b it can be seen that the damper housing 71 in addition to a translatory Shifting movement relative to the carrier 4 has also carried out a (slight) pivoting movement relative to the carrier 4 .

Starting from the previous FIGS. 4a to 5b, an opening movement 0 of the actuating arm device 5 was carried out in FIGS. 6a and 6b. As a result, the actuating arm 52 has been pivoted upwards. This opening movement 0 was carried out until the stop 55 of the first damping transmission element 5a made contact with the stop counterpart 74 . In this position, the damping start position D is reached.

Since the damping devices 7 are in different maximum positions in FIGS. 6a and 6b, the actuating arm 52 assumes a different angular position at the damping start position D given in each case. Specifically, an opening angle of approximately 108° is given in FIG. 6a, while an opening angle of 100° is given in FIG. 6b.

If the opening movement 0 is continued from this respective damping start position D, the damper piston 72 is pushed into the damper housing 71 via the stop counterpart 74, as a result of which the damping device 7 unfolds its effect. As soon as the damper piston 72 is fully retracted, the maximum open position OS is reached (not shown).

The movement section of the movable furniture part 2 upstream of the maximum opening position OS is thus damped, with the damping start position D being set differently via the damper setting unit 8 . This allows different opening angles to be set for the start of the damping movement.

The same principle also applies to the closing movement S. Starting from FIGS. 4a to 5b, a closing movement S of the actuating arm device 5 was carried out in FIGS. 7a and 7b. As a result, the actuating arm 52 has been pivoted downwards. This closing movement S was carried out until the stop element 56 made contact with the second damping transmission element 5b as a result of the rotary movement of the actuating arm 52 about the axis of rotation X. In this position, the damping start position D is reached.

Since the damping devices 7 are in different maximum positions in FIGS. 7a and 7b, the actuating arm 52 assumes a different angular position at the damping start position D given in each case. Specifically, in FIG. 7a there is an opening angle of approximately 22°, while in FIG. 7b there is an opening angle of just under 33°.

If the closing movement S is continued from this respective damping start position D, the second damping transmission element 5b is rotated counterclockwise about the pivot pin 57 via the stop element 56, as a result of which the damping transmission element 5b presses on the damper piston 72 via the stop 58 and pushes it into the damper housing 71 , Which in turn causes the damping device 7 to exert its effect. As soon as the damper piston 72 is fully retracted, the closed position SS is reached (not shown).

8 shows the entire piece of furniture 100 in a perspective view. The power supply unit 21 can be seen in this view, via which an electromotive furniture drive 1.2 (not visible here) can be supplied with energy.

In FIG. 8 there is also a detection device 22 on both sides of the furniture carcass 3 for detecting an overpressing movement and/or to trigger a closing movement S. If the movable furniture part 2 is in the closed position SS and a user presses on the movable furniture part 2, this is detected by the detection device 22, whereupon the control device 44 and the electromotive furniture drive 1.2 initiate an opening movement 0 of the furniture drive system 1 is initiated. When the movable furniture part 2 is open, as in FIG. 8, a user can press directly on one of the detection devices 22, whereupon a closing movement S of the furniture drive system 1 is initiated via the control device 44 and the electromotive furniture drive 1.2.

In FIG. 9 only the furniture carcass 3 together with the furniture drive systems 1 arranged on both sides of the furniture carcass 3 is shown in a perspective view. The protective screen 23 of the electromotive furniture drive 1.2 is clearly visible.

10 shows a perspective view of the furniture drive system 1, which has the mechanical actuator 1.1 and the electromotive furniture drive 1.2. These two units 1.1 and 1.2 are detachably connected to one another laterally via their respective housings. The entire furniture drive system 1 can be fastened to a furniture body 3 via the carrier 4 . The electromotive furniture drive 1.2 has the protective cover 23.

11 again shows the furniture drive system 1 in perspective, but with the protective screen 23 being omitted, as a result of which the view of the cover 24 that forms the housing of the electromotive furniture drive 1.2 is clear. A visual information signal H can be displayed on this cover 24 of the furniture drive system 1 .

In Fig. 12, the electromotive furniture drive 1.2 and the mechanical actuator 1.1 are shown separately. In the housing of Mechanical actuator 1.1 is a (curved) engagement opening 25 is formed, through which an intervention in the actuating part 58 of the actuating arm device 5 is possible.

Matching this, FIG. 13, which shows a different perspective of the furniture drive system 1, shows the driver 31 protruding from a (bent) exit opening 26 in the housing of the electromotive furniture drive 1.2.

This side of the electromotive furniture drive 1.2, which faces the mechanical actuator 1.1, forms the interface 90, via which the two drives 1.1 and 1.2 can be detachably connected to one another. From this interface 90, which is aligned along a vertical plane, part of the identification device 91—specifically the mechanical feeler element 96—protrudes in the direction of the mechanical actuating drive 1.1.

As can be seen in Fig. 13, the interface 90 comprises the connecting plate 93 (which also forms the housing) and a number of connecting elements 94.

The connecting counterparts 95 corresponding to the connecting elements 94 can be seen in FIG. 12 . These connecting counterparts 95 are formed in or on the housing of the mechanical actuator 1.1. The connecting elements 94 can be releasably connected to the connecting counterparts 95 by snapping, sliding, clipping, or the like.

In Fig. 14 only the housing of the electromotive furniture drive 1.2 including cover 24 is shown.

15 shows the electromotive furniture drive 1.2 with a view of the side facing the mechanical actuator 1.1. The driver 31 is in the illustrated embodiment as a pin formed, which is mounted limited in a guide contour (outlet opening 26) which is formed in the housing. The driver 31 protrudes beyond the housing on the side facing the mechanical actuator 1.1.

In FIG. 15 the connecting plate 93 and the connecting elements 94 as well as the mechanical feeler element 96 of the identification device 91 can again be seen particularly well.

16 shows the electromotive actuator 1.2 of the furniture drive system 1 in a perspective detail view, with the part of the cover 24 pointing in the direction of the mechanical actuator 1.2 being omitted.

The electromotive furniture drive 1.2 includes an electric motor 30 for electromotive support of the movement of the movable furniture part 2, which can be attached to the actuating arm 52. Furthermore, the electromotive furniture drive 1.2 comprises a driver 31 that can be (indirectly) driven by the electric motor 30 for transmitting a torque of the electric motor 30 to the mechanical actuator 1.2 or to the actuating arm 52 and a furniture part 2 that may be connected thereto.

The mechanical actuator 1.1 and the electromotive furniture drive 1.2 can be detachably connected to one another. As a result, the electromotive furniture drive 1.2 can be easily connected to or disconnected from the mechanical actuator 1.1.

The components of the electromotive furniture drive 1.2 can be arranged in a housing that encompasses the cover 24, as shown. The housing is at least partially on the mechanical actuator 1.2 and separates in the illustrated Exemplary embodiment the mechanical actuator 1.1 of the assembly of the electromotive furniture drive 1.2.

Instead of a housing, a mounting plate can also be used, for example, which does not enclose the structural unit of the electromotive furniture drive 1.2, but only delimits and supports it on one side.

A gear 32 is provided between the electric motor 30 and the driver 31 and converts a torque of the electric motor 30 into a pivoting movement of the driver 31 about an axis of rotation 33 . The gear 32 includes several gear stages (worm 40 and gears 34, 35, 36, 37, 38 and 39). The gear stages 34 to 40 each mesh with one another via gearing. Furthermore, the transmission 32 includes an overrunning clutch 41 which is integrated into the gear 36 and an overload clutch 42 which is integrated into the gear 39 .

The electromotive furniture drive 1.2 also has its own damping device 43 for damping the movement of the driver 31 about the axis of rotation 33.

Returning to FIG. 1, the following is described in more detail.

The electromotive furniture drive 1.2 has an identification device 91. This in turn has a sensor 92 and a mechanical feeler element 96, which is arranged in the area of the interface 90 with the mechanical actuator 1.1. The mechanical actuating drive 1.1 in turn has a feeler element counterpart 97 that corresponds to the mechanical feeler element 96 (schematically indicated).

When connecting the electromotive furniture drive 1.2 to the mechanical actuator 1.1, the configuration K des mechanical actuator 1.1 identifiable. Specifically, the mechanical probe element 96 contacts the probe element counterpart 97 when connecting. This probe element counterpart 97 represents a parameter P of the mechanical actuating drive 1.1. The contact moves the mechanical feeler element 96 , the position of the feeler element 96 being able to be detected by the sensor 92 .

The parameter P of the mechanical actuator 1.1 detected by the sensor 92 is transmitted to the control device 44. A data record F is stored in the control device 44 . This data set F contains—as shown by way of example in FIG. 1—several configurations K of the mechanical actuator 1.1. Specifically, there are eight different configurations K, which are made up of the three furniture flap types HF, HS and HL and the three performance factors L of the energy store 6.

The identification device 91 then uses the control device 44 to compare the parameter P detected by the sensor 92 with the data sets F, and the current configuration K _act of the mechanical actuator 1.1 is identified.

Control signals I can then be output to the electric motor 30 via the control device 44 depending on the current configuration K _at of the mechanical actuator 1.1 identified via the identification device 91.

Details of the identification device 91 are shown in FIG. Specifically, FIG. 17 shows the pushbutton element 96 rotatably mounted on the housing (preferably on the connecting plate 93 of the interface 90, not shown here). This probe element 96 is about a - preferably aligned at right angles to the vertical plane - axis of rotation T is rotatable, the rotatably mounted probe element 96 a mechanical Actuator 1.1 facing, relative to the axis of rotation inclined scanning surface B has.

It can be clearly seen in Fig. 17 that the inclined scanning surface B has a scanning line Bl lying on the scanning surface B, radially away from the axis of rotation T, closest to the interface and a scanning line B2 lying on the scanning surface B, radially away from the axis of rotation T and furthest from the interface having. The scanning line B2 furthest from the interface also forms a scanning nose N that can be moved into the scanning element counterpart 97 .

In the embodiment variant according to FIG. 17, the rotatable mechanical feeler is connected to a sensor 92 (not shown here) via two gear wheels. Other movement transmission variants are also possible.

18 shows a section through the electromotive furniture drive 1.2 in the area of the electric motor 30 and through the mechanical scanning element 96, with the scanning surface B and the scanning nose N also being clearly visible. The mechanical feeler element 96 is resiliently mounted along the axis of rotation T. The rotational movement or rotational position of this mechanical scanning element 96 can be detected via the sensor 92 .

The perspective representation according to FIG. 19 shows the inclined scanning surface B together with the scanning nose N and the shape of the mechanical scanning element 96 particularly well.

In contrast to FIG. 19, FIG. 20 also shows the housing of the electromotive furniture drive 1.2. The mechanical pushbutton element 96 protrudes through this housing through an opening in the connecting plate 93 . 21 shows a perspective view of the housing part 89 of the mechanical actuator 1.1 facing the interface 90. The probe element counterpart 97 is formed in this housing part 89 .

In Fig. 22, this probe element counterpart 97 is shown in detail, it being designed as an embossing formed in the housing sheet metal.

Fig. 23 shows the probe element counterpart 97 and the opposite, still spaced mechanical probe element 96 before connecting. In FIG. 24 there is still a slight spacing, while in FIG. 25 the two parts 96 and 97 have connected, the feeler element 96 having rotated about the axis of rotation T depending on the shape of the feeler element counterpart 97 . The connecting elements 94 and the connecting counterparts 95 are also connected to each other.

Fig. 26 shows the housing part 89 in a plan view together with the embossed counter-piece of the pushbutton element 97.

A detail from FIG. 26 is shown in FIG. The probe element counterpart 97 has a recess into which the probe nose N can penetrate when connecting. The probe element counterpart 97 has a projection 99 which projects into the recess and which defines or represents the parameter P of the mechanical actuating drive 1.1. This means that during the production of the housing part 89 of the mechanical actuator 1.1, this pushbutton element counterpart 97 is produced or embossed for later identification when connecting to the electromotive furniture drive 1.2.

In Figs. 28 and 29, the projection 99 is offset. This probe element counterpart 97 thus represents a different parameter P. The type recognition can also be explained with reference to FIG. Starting from a home position (vertically up), there is a 10° dead zone on either side of that home line. Then there are - similar to a clock - twelve areas, each with about 28.3° (=340°). Each of these areas corresponds to a parameter P, from which a configuration K can in turn be identified. Depending on how the projection 99 is embossed, the configuration K can be recognized via the identification device 91 .

In other words, the mechanical probe element 96 is aligned with the embossing in the housing sheet (counterpart of the probe element 97). The rotation of the feeler element 96 is detected and evaluated by the electronics of the control device 44 .

31 to 42 show a further embodiment with an alternative embodiment of the mechanical feeler element 96 and the feeler element counterpart 97 .

In Fig. 31 is a perspective view of a furniture drive system comprising a mechanical actuator 1.1 and an electromotive furniture drive 1.2. The protective screen 23 is also shown. The probe element counterpart 97 is designed in the form of three recesses on the housing part 89 of the mechanical actuator 1.1.

Fig. 32 is identical to Fig. 31 with the area of the mating tactile element 97 circled.

In Fig. 33, this circled area is shown enlarged. It can thus be seen that in this case the two right-hand recesses of the probe element counterpart 97 are empty, while the left-hand recess is filled. The three recesses thus form a Art code reflecting the parameter P of the mechanical actuator 1.1.

34 shows the furniture drive system 1 from a different perspective, so that the view of the interface 90 of the electromotive furniture drive 1.2 is also partially clear. The mechanical feeler element 96 can already be seen in the circled area.

35 shows this circled area enlarged. It can be seen that this mechanical tracer element 96 has three displaceably mounted tracer pins 98 which protrude through the connecting plate 93 .

36 shows the housing part 89 of the mechanical actuator 1.1 in perspective; the rest is hidden. Of the electromotive furniture drive 1.2, only the mechanical pushbutton element 96 is shown in the circled area, the remaining components of the electromotive furniture drive 1.2 are hidden for better illustration.

FIG. 37 shows the circled area of FIG. 36 enlarged. The individual tracer pins 98 are each surrounded by a compression spring 88 and are prestressed in the direction of the housing part 89 by this respective compression spring 88 .

38 again shows the housing part 89 together with the mechanical scanning element 96 from a different perspective.

In the enlarged representation according to FIG. 39 it can be seen that the left-hand recess of the contact element counterpart 97 is filled, so that the tracer pin 98 of the mechanical contact element 96 is present. On the other hand, the two right-hand feeler pins 98 project into the two open recesses of the feeler element counterpart 97 . These different positions of the tracer pins 98 can be detected by a sensor 92 .

In FIG. 40, the housing part 89 is shown in perspective with the scanner pins half cut open.

The circled area of FIG. 40 is enlarged in FIG. It can be seen that the two right-hand tracer pins 98 penetrate into the recesses of the tracer element counterpart 98, while the left tracer pin 98 rests against the projection 99 filling the recess.

42 shows a plan view of the three tracer pins 98, it being clearly evident that two tracer pins 98 penetrate the housing part 89 in the region of the recesses of the tracer element counterpart 97.

Overall, in this embodiment variant shown in FIGS. 31 to 42 with three feeler pins 98—depending on how many and which recesses of the feeler element counterpart 97 are filled—there are nine possible variants for parameter P of the mechanical actuator 1.1.

If the mechanical feeler element 96 has, for example, only two displaceably mounted feeler pins 98 (not shown), only a maximum of four parameters P and configurations K identifiable therefrom can be determined and differentiated.

Equally, with four displaceably mounted tracer pins 98 (not shown), there are sixteen different configurations K, etc. 43a shows a further structural configuration of the mechanical scanning element 96 comprising a scanning pin 98. The displaceably mounted scanning element 96 (the number is generally arbitrary) can be brought into contact with a conductor track 103 (illustrated in the enlarged detail below the mechanical actuator 1.1), wherein the conductor track 103 comprises two star-shaped conductor track contours 104 for determining a parameter P of the mechanical actuator 1.1.

In Fig. 43b it can be seen that the displaceably mounted tracer element 96 - comprising the tracer pin 98 - has a first spring 101 arranged in certain areas inside the tracer pin 98 for determining a parameter P of the mechanical actuator 1.1 and a second spring 102 arranged in certain areas on the outside of the tracer pin 98 includes.

The first spring 101 is electrically isolated from the scanning pin 98 in the form of plastic or metal and can be brought into contact with the two conductor track contours 104 of the conductor track 103 .

44a shows the electromotive furniture drive 1.2 in connection with the mechanical actuator 1.1. The mechanical actuator 1.1 can be determined (generally possible in all exemplary embodiments) via a combination of a parameter P determined via the identification device 91 and an opening angle of the mechanical actuator 1.1, with the opening angle (e.g. by a maximum angle of inclination or a specific angle between two End positions of the mechanical actuator 1.1 can be determined by a reference run of the furniture drive system 1. To identify this mechanical actuator 1.1, the probe element counterpart 97 acts as an abutment, so that the first spring 101 contacts the conductor track 103—both conductor track contours 104. In general, the displaceably mounted probe element 96 can be exactly one or a large number of separate ones from the interface

90 have tracer pin(s) 98 protruding at right angles to the vertical plane, the displaceably mounted tracer element 96 being able to be arranged on the conductor track 103 and optionally arranged on the mechanical actuating drive 1.1 for contacting a defined area of the conductor track 103 (the mechanical tracer element 96 on the housing part is preferred 89 arranged). As a result, the mechanical actuating drive 1.1 can be identified by means of a defined positioning of the tracer pin 98 with a reduced number of mechanical tracer elements 96.

44b shows that no probe element counterpart 97 acts as an abutment to identify this mechanical actuating drive 1.1, so that the first spring 101 is situated without contact with the conductor track 103 due to a spacing. Structural details of the displaceably mounted mechanical scanning element 96 (cf. FIG. 41)--such as the projection 99--can be used as an alternative or in addition to this embodiment of the mechanical scanning element 96.

Finally, the two following variants (not shown) should also be mentioned.

It can be provided that via the identification device

91 only the configuration K is identifiable with regard to the power factor L. For the identification of the furniture flap types HF, HS and HL - for example as described in EP 2315 891 B1 - a path measuring device can be provided, by means of which the path that can be covered by the actuating arm between its two end positions can be determined, with the furniture flap type depending on the measurement result of this path measuring device is identifiable. There is thus a mixed variant between the one according to the invention identification when connecting and the identification of a configuration by the actuator arm movement.

So far, the mechanical feeler element 96 has always been described as a protruding component. However, it is entirely possible for this mechanical probe element 96 to be in the form of a depression and for the probe element counterpart 97 to be a corresponding counterpart, with the same basic principles applying to identification in this mechanical reversal.
