- the rack 9 (or equivalents) can also be subsequently coupled to the drawer rail 9 to transmit movement from the electric drive device 6 to the movable furniture part 2.
- the interfaces 34, 35 in connection with the components to be arranged thereon therefore comprise a multifunction - on the one hand to ensure user-friendly retrofitting and on the other hand to connect a large number of flexibly exchangeable and varying movement technologies. Multiple interfaces for a large number of movement technologies can thus be avoided, whereby individual movement technologies can be connected as an add-on in an assembly-friendly manner. Additional installation space for the arrangement of the electric drive device 6 does not have to be provided, whereby the energy supply for the movable furniture part 2 and a sufficient transmission of movement to the movable furniture part 2 are also facilitated.
- Fig. 7b differs from Fig. 7a only in that the electric drive device 6 is shown in a perspective view.
- the electric motor 7 is arranged within a housing 47 with a thickness 67 in the vertical direction 15 in the use position 14 of the arrangement of less than 100 mm. It is possible to achieve thicknesses 67 of less than 80 mm.
- the thickness 67 is preferably less than 60 mm (and less than 40 mm is also conceivable), so that in conventional furniture a furniture part front 23 protrudes below the underside of the electric drive device 6.
- Fig. 8a shows that the electric motor 7 of the electric drive device 6 is in the form of a brushless external rotor motor 66, although in general brushed external rotor motors 66, disc rotor motors or rod motors can also be provided. External rotor motors and disc rotor motors have a particularly flat design and are therefore preferred.
- the electric drive device 6 comprises a data interface 63 for the wired transmission of at least one digital data set stored in a storage unit, wherein the data interface 63 can generally be designed as an alternative or in addition to the radio signal-transmitting transmission of the digital data set.
- the electric drive device 6 comprises an electric motor 7 that can be supplied with 230 V for at least partially automated movement of the movable furniture part 2 relative to the fixed furniture part 1, wherein the distance measuring device 33 is arranged on the electric drive device 6 or represents an integral part of the drive device 6 in interaction with the electric motor 7 and is integrated in the housing 47 of the electric drive device 6.
- the distance measuring device 33 is arranged on the electric drive device 6 or represents an integral part of the drive device 6 in interaction with the electric motor 7 and is integrated in the housing 47 of the electric drive device 6.
- an arrangement within the housing 47 is not absolutely necessary.
- the position in the form of the absolute distance traveled is stored as a dynamic data set and the speed as a dynamic data set for simulating the model via the computing unit of the microcontroller 37 or the control and/or regulation unit 44, at least temporarily in the storage unit.
- the position measuring device 33 comprises a first position sensor 53 in the form of a sensor wheel designed as a gear 17 and a further position sensor 54 in the form of a further sensor wheel designed as a gear 17, wherein the absolute path can be clearly determined via a relative rotational position of the position sensors 53, 54.
- the first position sensor 53 and the further position sensor 54 are in the form of gear stages 55 of the electric drive device 6, whereby these gear stages 55 are not required for a transmission of the drive from the electric motor 7 to the drawer rail 5; further gear stages 55 are used for this.
- a transmission ratio in the range between 1.01:1 and 1.2:1 that can be used for the position measuring device 33 can be mediated via the first sensor wheel.
- a transmission ratio in the range between 1.2:1 and 2.3:1 can be mediated between the first sensor wheel and the further sensor wheel, and a transmission ratio in the range between 1.5:1 and 2:1 can be mediated via the first sensor wheel and the further sensor wheel.
- the absolute path of the movable furniture part 2 is determined starting from a reference position via a sum or a difference of rotation angles of the two position sensors 53, 54, so that a distancing between the movable furniture part 2 and the fixed furniture part 1 can be clearly calculated.
- the position measuring device 33 comprises a magnetic bearing 57 over the housing 47 of the electric drive device 6 and a plastic part 58.
- the plastic part 58 acts as a double function as a circuit board for a microcontroller 37.
- an exemplary method for moving the movable furniture part 2 relative to the furniture part 1 at least in some areas along the path 13 of the movable furniture part 2 between a closed position and a partial or complete open position 30 of the movable furniture part 2 by means of the electric drive device 6 and a path measuring device 33 is explained: Via the path measuring device 33, a position of the movable furniture part 2 relative to the fixed furniture part 1 is clearly determined as the absolute path traveled by the movable furniture part 2 relative to the fixed furniture part 1, and the movable furniture part 2 is moved translationally by the electric drive device 6 between the closed position and the open position 30 along the guide device 3 over a partial area of the path 13 depending on the absolute path determined by the path measuring device 33.
- a drive of the drawer rail 5 over the entire path 13 is generally possible due to the constant coupling between the rack 9 and the electric drive device 6, but is not absolutely necessary.
- the movable furniture part 2 can be driven with a speed profile adapted to the determined speed or the determined absolute path via a control and/or regulating device 44 or a microcontroller 37, wherein the electric drive device 6 is activated at a predefined speed or at a predefined absolute path.
- a control and/or regulating device 44 or a microcontroller 37 wherein the electric drive device 6 is activated at a predefined speed or at a predefined absolute path.

- the arrangement comprises a stabilization device 70 for laterally stabilizing the movable furniture part 2 along the guide device 3.
- a stabilization device 70 for laterally stabilizing the movable furniture part 2 along the guide device 3.
- sufficient lateral stabilization can be generated via the movable furniture part 2 itself. It is conceivable to connect the stabilization device 70 to the second interface 35 (see Fig. 7a).
- the synchronization rod 20 with the two further racks 19 can be provided as a separate configuration as an add-on, wherein at least one of the three component parts can be connected to the second interface 35, the rack 9, the body rail 4 or the electric drive device 6.
- an intersection point of the sensor angles corresponding to an extension length of approximately 245 mm is marked with a square, whereby this intersection point corresponds to three complete rotations of the first position sensor 53 and five complete rotations of the second position sensor 54.
- the difference in the rotation angles corresponds to 36°, so that the position is clearly defined.
- Another intersection point of the sensor angles corresponding to an absolute travel of approximately 165 mm is marked with a circle, whereby this intersection point corresponds to two complete revolutions of the first position sensor 53 and five complete revolutions of the second position sensor 54.
- the difference in the rotation angles corresponds to 144°, so that the position is clearly defined.
- a signal tolerance of the first position sensor 53 based on a maximum number of six rotations for a clear position determination is equal to 60°.
- a signal tolerance for the second position sensor 54 based on a maximum of 10 revolutions is equal to 36°.
- a tolerance can be reduced to +/- 30° for the first position sensor 53 and +/- 18° for the second position sensor 54, which is sufficiently exact for a precise determination of the absolute path via both position sensors 53, 54.
- a redundancy of intersection points for determining the absolute path can occur over long distances 13, whereby this undesirable situation can be eliminated by an entry in a memory unit or a varying translation. It is also conceivable to use additional sensors.
