Description

Field of the Invention

[0001] The present invention relates to a method for moving a movable furniture part, in particular a drawer, relative to a fixed furniture part, in particular a furniture body, along a guiding device, in particular a drawer pull-out guiding device, by means of a computing unit and at least one electric drive device that can be supplied with, in particular, 230 V voltage, the electric drive device being configured to move the movable furniture part relative to the fixed furniture part at least partially automatically via an electric motor. Furthermore, the present invention relates to a microcontroller for carrying out the method, an electric drive device for moving a movable furniture part relative to a fixed furniture part at least partially automatically via an electric motor with the aid of at least one such microcontroller, an arrangement system composed of such an electric drive device and a fixed furniture part, and a computer program product. Background Art

[0002] A method for moving a movable furniture part is known from document EP 1 323 364 A1, in which a drawer is moved by means of a drive unit controlled by a triggering device. The triggering device includes, for this purpose, two manually actuable touch switches, such as drag switches, arranged on the drawer for achieving three different switching states. The triggering device can be activated based on the relative position of the furniture part components or by tapping on the furniture part components to generate switching pulses.

[0003] A method for moving a movable furniture part is also known from document EP 1 323 363 A1, in which the drive unit is controlled by a regulating device and a force measuring device to automatically support in both directions the movement desired by the drawer user. As a supplement, a position measuring device can be provided, which generates position signals by means of which the instantaneous actual position, actual speed, and actual acceleration as a function of the measured position can be calculated. It is also possible to determine target values such that, under different loads of the drawer, substantially the same force consumption can be generated.

[0004] A method for moving a movable furniture part is also known from document EP 2 642 899 A1, in which different triggering sensitivities can be generated via two sensors when a force is applied to the drawer.

[0005] The disadvantage of the prior art is that the existing control units for moving movable furniture parts - especially due to limited computing and storage capabilities - can only perform basic control of the movement process of the movable furniture parts. Especially in the case of alternating forces and / or when the movable furniture part has a load or a change in the guiding device, this can lead to undesirable and inharmonious movement trajectories, in which the speed of the movable furniture part may be too fast or too slow, and being too fast or too slow may cause the movable furniture part to not be able to move to the desired end position or cause damage. Summary of the Invention

[0006] Therefore, the objective technical task of the present invention is to provide a method improved relative to the prior art, an electric drive device, an arrangement system, and a computer program product, which at least partially overcome the deficiencies in the prior art and are particularly characterized by stronger functionality.

[0007] This task is solved by the features of claim 1.

[0008] Therefore, according to the present invention, the following method steps are carried out in chronological order:

[0009] - A microcontroller including a calculation unit and a storage unit in data connection or capable of establishing a data connection with the calculation unit determines a model of the movable furniture part according to at least one static data set stored in the storage unit;

[0010] - Manually move the movable furniture part from the open position or from a position between the open position and the closed position and / or vice versa;

[0011] - The microcontroller calculates a predicted movement trajectory of the movable furniture part along the guiding device according to at least one dynamic data set.

[0012] Thereby, the movement of the movable furniture part can be assisted in being recognized, wherein, for example, the movable furniture part can be driven in the closing direction or the opening direction such that the movable furniture part moves to the end position (closed position or open position) substantially noiselessly and / or without a huge force acting on the structural components. Generally, partial driving or full driving - especially over the entire path - to the end position is possible.

[0013] The movable furniture part can be forced by at least one electric drive device according to the predicted movement trajectory. The static data set can be related to the movable furniture part itself (excluding the basic movement data of the movable furniture part, such as speed), and the dynamic data set can be related to the manual movement of the movable furniture part (such as the actually existing speed of the movable furniture part), such that the microcontroller can calculate the predicted movement trajectory of the movable furniture part according to the manual movement of the movable furniture part.

[0014] As mentioned at the beginning, a microcontroller for performing such a method is also claimed, the microcontroller comprising a computing unit and a storage unit which is or can be established in a data connection with the computing unit, wherein the computing unit is configured to determine a model of a movable furniture part based on at least one static data set stored in the storage unit and / or to calculate a predicted movement trajectory of the movable furniture part along a guiding device based on a dynamic data set stored in the storage unit.

[0015] As mentioned at the beginning, an electric drive device for at least partially automatically moving a movable furniture part relative to a fixed furniture part via an electric motor is also claimed, the electric drive device having at least one of the above-mentioned microcontrollers.

[0016] As mentioned at the beginning, an arrangement system is also claimed, the arrangement system consisting of the above-mentioned electric drive device and a fixed furniture part, in particular a furniture body, wherein the fixed furniture part comprises two furniture panels which are vertically and parallel to each other in the use position of the arrangement system, wherein exactly one electric drive device is preferably fixedly arranged on one of the two furniture panels indirectly via a main guide rail of the guiding device, wherein at least one further triggering sensor - for activating the electric motor to achieve a closed position of the movable furniture part arranged on the fixed furniture part - is fixedly arranged on the second furniture panel, preferably on the main guide rail arranged on the second furniture panel, wherein it is preferably provided that: the at least one further triggering sensor comprises a damping device and / or a buffer, and / or is connected to the electric drive device in a data connection or can be established in a data connection via a radio connection and / or a cable connection.

[0017] Furthermore, the arrangement system may also comprise an electric drive device without a corresponding microcontroller.

[0018] As mentioned at the beginning, a computer program product is also claimed, the computer program product comprising instructions which, when executed by a computing unit, cause the computing unit to perform such a method from a storage unit which is in a data connection with the computing unit or can be established in a data connection.

Detailed implementation

[0033] Figure 1a Shows a piece of furniture with a movable furniture part 2 in the form of a drawer, which can be moved relative to a fixed furniture part 1 in the form of a furniture body via a guiding device 3 in the form of a drawer pull-out guiding device by means of an electric drive device 6.

[0034] The movable furniture part 2 can be divided into a first movable furniture part 41 and additional movable furniture parts 42, where these additional movable furniture parts 42 are arranged below the movable furniture part 41 in the use position 14 of the arrangement system.

[0035] However, the furniture is not limited to drawers and can generally include other containers. For example, the furniture can be a furniture body with a baffle, a cabinet with folding doors and / or sliding doors, or similar forms.

[0036] Figure 1b Shows the furniture with the movable furniture part 2 removed, and the arrangement system of the furniture includes a fixed furniture part 1, a movable furniture part 2 movable relative to the fixed furniture part 1, and two guiding devices 3 for guiding the movable furniture part 2 relative to the fixed furniture part 1.

[0037] The arrangement system includes an electric drive device 6 for at least partially automatically moving the movable furniture part 2 relative to the fixed furniture part 1, and this electric drive device includes a motor 7 with a supply voltage of 230 V. The energy supply of the motor 7 is generally arbitrary and can also operate with different voltages. Generally speaking, especially due to the characteristics of the local or regional power grid, a lower voltage can also provide sufficient energy for the motor 7.

[0038] The guiding devices 3 each include a main guide rail 4 arranged on the fixed furniture part 1 and a slide rail 5 arranged on the movable furniture part 2. Generally speaking, an intermediate rail can be at least partially arranged between the main guide rail 4 and the slide rail 5, however this is usually - especially for fully pulling out the movable furniture part 2 by the front-side arrangement of the electric drive device 6 and the connection with the rack 9 - unnecessary.

[0039] In the detail view, the connection of the electric drive device 6 to the main guide rail 4 and the connection of the rack 9 to the slide rail 5 are shown enlarged, wherein the slide rail 5 includes a first interface 34 (or a plurality of first interfaces 34 if necessary), which is suitable for fixing the ejection device 11 and the pulling-in device 8 to the slide rail 5.

[0040] The pulling-in device 8 is provided at the first interface 34, which is usually unnecessary. Alternatively or additionally, an ejection device 11, especially a mechanical or electric one, can be arranged at the first interface 34. Preferably, the ejection device 11 includes a Tip-On-Funktion, via which the ejection process can be triggered by an overpressure action.

[0041] The main guide rail 4 includes a second interface 35 (or a plurality of second interfaces 35 if necessary), which is suitable for fixing a driving member 36 for the ejection device 11 or the pulling-in device 8 to the main guide rail 4. The second interface 35 is (invisibly in the view) located on the lower side of the main guide rail 4 (see Figure 6 ).

[0042] The electric drive device 6 is arranged at the second interface 35, and the rack 9 for transmitting power from the electric drive device 6 to the slide rail 5 is arranged at the first interface 34.

[0043] The connection of the electric drive device 6 is achieved via a snap connection 71 and via a pivoting process for hooking (see Figure 6 ). During the insertion process of the pulling-in device 8 or the slide rail 5 by translation, the connection of the rack 9 is completed via the snap connection 71. For example, the snap connection 71 can have a snap-in bar or a locking projection 81 (on the rack 9, the pulling-in device 8 or the slide rail 5), wherein alternatively or additionally, a hook 75 can also be used. In this embodiment, the rack 9 is connected to the pulling-in device 8, which can have an ejection device 11 if necessary, or the ejection device 11 can be connected to the pulling-in device if necessary (similarly, alternative devices for the pulling-in device 8 can also be considered). Similarly, it is also possible to directly connect the rack 9 to the slide rail 5. It is also possible to indirectly connect the electric drive device 8 (for example via a driving member 36 for the pulling-in device 8), with a direct connection being preferred.

[0044] The width of the rack 9 is designed such that it also includes equivalent means for transmitting power between the electric drive device 6 and the slide rail 5, such as a belt (optionally with teeth 18), a chain or the like.

[0045] The electric drive device 6 is arranged substantially completely below the movable furniture part 2 on the main guide rail 4 in the use position 14 of the arrangement system, where, if necessary, the front part 23 of the furniture part (for example, in order to access the trigger sensor 59) can extend vertically in the direction 15 below the top surface of the electric drive device 6 or below the electric drive device 6. The bottom plate of the movable furniture part 2 is arranged completely above the electric drive device during the movement of the movable furniture part. In use, the movable furniture part 2 moves past the electric drive device 6.

[0046] The electric drive device 6 is fixedly arranged on the main guide rail 4 and is always connected to the rack 9 for transmitting motion along the entire path 13 of the movable furniture part 2 along the guiding device 3.

[0047] The movable furniture part 2 includes a front part 23 of the furniture part, wherein the electric drive device 6 on the main guide rail 4 is arranged in the area of the free end 24 of the main guide rail 4 facing the front part 23 of the furniture part in the use position 14 of the arrangement system.

[0048] The electric drive device 6 is arranged flush with the slide rail 5 or the rack 9 in the closed position. The pull-out loss caused by fastening the main guide rail and / or by using a specific type of trigger sensor can be compensated for by the rack 9.

[0049] The electric drive device 6 is arranged substantially flush with the free end 24 of the main guide rail 4 in the closed position and the open position 30.

[0050] The fixed furniture part 1 includes two furniture boards 64 that are vertically oriented and parallel to each other in the use position 14, wherein exactly one electric drive device 6 is fixedly arranged indirectly via the main guide rail 4 on one of the two furniture boards 64. However, generally speaking, additional electric drive devices 6 or additional racks 9 can also be arranged on the opposite furniture boards 64, but this is not mandatory.

[0051] The movable furniture part 2 includes a front part 23 of the furniture part in the use position 14 of the arrangement system, wherein the electric drive device 6 on the main guide rail 4 is arranged in the area of the free end 24 of the main guide rail 4 facing the front part 23 of the furniture part (substantially flush with the free end 24 or the slide rail 5 in the closed position or the rack 9 in the closed position).

[0052] Figure 2 The connection of the electric drive device 6 to the main guide rail 4 is shown without the surrounding furniture parts 1, 2, wherein the slide rail 5 is fully extended on the path 13, which is the pull-out path of the movable furniture part 2.

[0053] In the enlarged detail view, the connection of the rack 9 to the slide rail 5 or the pulling-in device 8 is visible, wherein the ejecting device 11 is shown in dashed lines and can alternatively or additionally be arranged at the first interface 34. It is also conceivable to provide a locking device 69 at the first interface 34 to inhibit the movement of the movable furniture part 2. The damping device 12 is integrated in the pulling-in device 8 and can also exist as a separate structural part.

[0054] Figure 3 The guiding device 3 with an electric drive device 6 is shown, which is used to automatically move the movable furniture part 2 or the slide rail 5 by means of a motor 7 (which can supply a voltage of 230 V).

[0055] The pulling-in device 8 for the movable furniture part 2 and the rack 9 in operative connection with the electric drive device 6 are assembled, wherein the pulling-in device 8 is arranged directly on the slide rail 5 and the rack 9 is arranged indirectly via the pulling-in device 8 at the first interface 34 of the slide rail 5. Generally, the rack 9 can alternatively or additionally come into direct contact with the slide rail 5.

[0056] The rack carrier 9 is detachably arranged on the support device 10 and the support device 10 is detachably arranged on the pulling-in device 8.

[0057] The detachable connection of the support device 10 in this context means a non-violent connection that is preferably tool-free to release.

[0058] The support device 10 is arranged in the horizontal direction 16 between the rack 9 and the pulling-in device 8, and generally, it can also be arranged on the rack 9 facing downwards in the vertical direction 15.

[0059] The support device 10 or the pulling-in device 8 can include a mechanical or electric ejecting device 11, wherein the pulling-in device 8 includes a damping device 12 to inhibit the movement of the movable furniture part 2 in the area of the closed position.

[0060] The fixed electric drive device 6 is always in connection with the rack 9 along the entire path 13 of the guiding device 3 to transmit motion, wherein the electric drive device 6 includes a gear 17 that meshes with the rack 9 and is connected to the motor 7.

[0061] The rack 9 is laterally arranged between the electric drive device 6 and the slide rail 5 along the entire path 13.

[0062] In this embodiment, exactly one electric drive device 6 is arranged on one of the two main guide rails 4 of the guiding device 3 and exactly one rack 9 is arranged on one of the two slide rails 5 of the guiding device 3. Generally, two electric drive devices 6 can also be used on these two main guide rails 4.

[0063] The power supply for the electric drive 6 or any additional current-consuming devices (Stromsenke) that may be present - such as Figure 6 the lighting device 31 in

[0064] is effected via the main guide rails 4, where alternatively or additionally, power supply can be via the rack 9. The power supply can be guided between the two main guide rails 4 of the two provided guiding devices 3, for example to supply another triggering sensor 65. Similarly, each main guide rail 4 (or the rack 9) can also be powered individually.

[0065] The teeth 18 of the rack 9 are oriented in the horizontal direction 16 in the direction away from the slide rail 5 in the usage position of the arrangement system, where generally speaking, they can also be oriented downwards in the vertical direction 15.

[0066] The rack 9 is preferably designed to be flexible so that reliable, smooth and continuous motion transmission can be ensured through elastic deformation.

[0067] Due to the separable connection - especially the double separable connection - an overload protection clutch can be formed via the relevant structural components, so the overload protection clutch 68 of the electric drive unit 6 can be omitted. For example, in the case of an increased load on the rack 2 (such as during shaking or when applying inappropriate forces to the movable furniture part), the tolerance generated in the interaction between the gear 17 and the rack 9 under load can prevent complete decoupling between the electric drive 6 and the rack 9 - without losing the function of the overload protection clutch. Thus, the position of the slide rail 5 relative to the main guide rail 4 can still be clearly determined via the relative position between the rack 9 and the gear 17. Decoupling from the electric motor 7 is not required and can be achieved, for example, via an overrunning clutch 29. The necessary reference run can be prevented, where the support device 10 acts as a coupling device.

[0068] Figure 4 An enlarged detail view of the guiding device 3 together with the slide rail 5 in the area of the coupling device on the back of the furniture part for the movable furniture part 2 is shown.

[0069] The slide rail 5 includes a support device 21 for the rack 9, wherein the support device 21 is arranged on the slide rail 5 and the rack 9, and during the relative movement of the slide rail 5 and the main guide rail 4, the rack 9 and the support device 21 can pass through the bracket 22 of the electric drive device 6 for connecting the electric drive device 6 to the main guide rail 4.

[0070] Figure 5 The guiding device 3 is shown, in which the coupling between the gear 17 of the electric drive device 6 in operative connection with the motor 7 and the teeth 18 of the rack 9 is marked in enlarged detail view.

[0071] The motor 7 (or the electric drive device 6) includes a gear 17 meshing with the rack 9 in the coupling of the transmission stage 55 of the electric drive device 6.

[0072] The gear 17 is oriented in the horizontal direction 16 in the direction pointing to the slide rail 5 in the use position 14 of the arrangement system, and it is also feasible that the gear 17 of the electric drive device 6 is oriented upward in the vertical direction 15.

[0073] The rack 9 is arranged between the electric drive device 6 and the slide rail 5. The guiding device 3 is in the closed position, whereby the movable furniture part 2 arranged on the slide rail 5 will be in the end position.

[0074] In order to improve the power transmission degree of the energy transmitted to the movable furniture part via the electric drive device 6 in terms of time point and / or intensity, the microcontroller 37 controls the electric drive device, and this microcontroller functions as a control and / or regulation device 44 and acts as a computing unit.

[0075] An exemplary method based on a computing unit for moving the movable furniture part 2 relative to the fixed furniture part 1 along the guiding device 3 via the electric drive device 6, which is used to move the movable furniture part 2 relative to the fixed furniture part 1 at least partially automatically via the motor 17, can be realized in the following way: The microcontroller 37 includes a computing unit and a storage unit maintaining a data connection with this computing unit. The microcontroller determines a model of the movable furniture part 2 according to at least one static data set stored in the storage unit, manually moves the movable furniture part 2 from a partial or fully open position 30 and the closed position in the direction of the closed position or vice versa, and the microcontroller 37 calculates a predicted movement trajectory of the movable furniture part 2 along the guiding device 3 according to at least one dynamic data set.

[0076] The static data set can include, for example, the mass of the movable furniture part 2, the frictional force of the movable furniture part 2 on the guiding device 3, the dimensions of the movable furniture part 2, the load of the movable furniture part 2, the dimensions of the guiding device 3, the path 13 along the guiding device 3, tolerance limits, and so on.

[0077] Path 13 generally depends on the pulling-out displacement of the movable furniture part 2 or the longitudinal extension of the rack 9. On this path, the drive is carried out at least partly via the electric drive device 6 by means of the automatic control device. The drive can be carried out on path 13; preferably, the drive is carried out on a partial area of path 13.

[0078] The dynamic data set can include, for example, an absolute distance covered by the movable furniture part 2 relative to the fixed furniture part 1, the speed of the movable furniture part 2, the load of the movable furniture part 2, the acceleration curve of the movable furniture part 2 (usually determined by the speed measuring device 52), the acceleration travel of the movable furniture part 2, the kinetic energy of the movable furniture part 2, and the like.

[0079] The static data set and the dynamic data set can be determined during a reference run of the movable furniture part 2 or via multiple reference runs - if necessary, in the case of a load change of the movable furniture part 2. As an alternative or in addition, the static data set can be stored in the storage unit without a reference run, and the static data set and the dynamic data set are compared with the data sets stored in the storage unit or corrected according to the stored data sets.

[0080] In this embodiment, the following aspects are specified, but do not necessarily have to be implemented:

[0081] The microcontroller 37 decides, based on the predicted movement trajectory, whether the electric drive device 6 should exert a force on the movable furniture 2 or whether the movable furniture part 2 should be manually moved in the idling area. The electric motor 7 includes an idling clutch 29, via which the force transmission from the electric motor 7 to the movable furniture part 2 is disconnected in the idling area.

[0082] The microcontroller 37 calculates, based on the at least one static data set and the at least one dynamic data set, whether the movable furniture part 2 reaches the closed position without the application of force by the electric drive device 6, wherein the speed at which the movable furniture part 2 enters the closed position is determined according to the damping power of the damping device 12 arranged on the movable furniture part 2 or the fixed furniture part 1.

[0083] The microcontroller 37 determines the speed profile of the drive of the movable furniture part 2 by the electric drive device 6 based on the predicted movement trajectory, wherein the electric drive device 6 exerts a force on the movable furniture part 2 according to the speed profile. The speed profile is generated based on the at least one static data set or the at least one dynamic data set, wherein the movable furniture part 2 is supplied with energy when the speed of the movable furniture part 2 is lower than the speed profile, and is braked by the electric drive device 6 when the speed of the movable furniture part 2 is higher than the speed profile, and power is started to be transmitted to the movable furniture part 2 when a predefined speed threshold or a predefined position threshold is reached.

[0084] The microcontroller 37 is equipped with a learning algorithm in the form of artificial intelligence, including a neural network with machine learning or deep learning, wherein the historical predicted movement trajectories are analyzed and compared with each other by means of the learning algorithm. The history of the predicted movement trajectories is used for the movement trajectories to be predicted in the future, the future speed profiles or the future decisions on applying forces to the movable furniture part 2 according to the respective static data sets or dynamic data sets.

[0085] The movement process of the movable furniture part 2 along the guide device 3 is used as training data for artificial intelligence. It has proven to be extremely advantageous to train the learning algorithm using different guide devices 3 and different forces applied or loads on the movable furniture part 2. The movement processes of the specifically existing guide device and the specific movable furniture part 2 can be added to the training data for learning, especially for continuous learning.

[0086] The electric drive device 6 remains fixed on the main guide rail 4 during the movement of the movable furniture part 2 and is always connected to the rack 9 arranged on the slide rail 5.

[0087] The movable furniture part 2 can be driven by the electric drive device 6, starting from the open position 30 or a position between the open position 30 and the closed position via the slide rail 5, through the entire path 13 up to the closed position and the open position 30 or only through a partial area of the path 13, wherein the force applied by the electric drive device 6 in the direction from the closed position to the open position is initiated by an overpressure action of the movable furniture part 2 or via only an electronic trigger sensor 59. In the idling area, the movable furniture part 2 can be manually moved within the non-driven area of the path 13 such that the motor 7 does not exert a force on the movable furniture part 2.

[0088] It has proven to be very advantageous that the driven area of the path 13 is between 50 mm and 150 mm in the direction of the open position 30, especially starting from the closed position, and between 5 mm and 20 mm in the direction of the closed position, especially starting from the fully open position 30.

[0089] The movement of the movable furniture part 2 in the direction of the closed position or the open position 30 can be inhibited, braked or prevented via an electric drive device 6, wherein the movable furniture part 2 is subjected to a force exerted by a pulling-in device 8 in the direction of the closed position within the region of the closed position. However, the pulling-in device 8 is not absolutely necessary, and the pulling-in device 8 can be replaced, for example, by the electric drive device 6.

[0090] An algorithm or computer program product comprising instructions for performing the method can be stored in the microcontroller 37 or the control and / or regulation device 44, can be transmitted on a data carrier signal or can be stored on a data carrier - in particular a non-volatile one.

[0091] The computing unit of the microcontroller 37 or the control and / or regulation device 44 is configured for this purpose to determine a model of the movable furniture part 2 based on the at least one static data set stored in the storage unit and to calculate a predicted movement trajectory of the movable furniture part 2 along the guide device 3 based on at least one - if necessary stored in the storage unit - dynamic data set. The electric drive device 6 comprises a computing unit.

[0092] The storage unit has a sufficient storage capacity to provide the information required for the model. The computing unit has sufficient computing power to calculate the model with the accuracy required in the furniture industry with respect to the speed profile to be transmitted to the movable furniture part 2. The storage capacity and computing power can be matched according to the required model accuracy or the accuracy of the output parameters - such as the speed profile - generated by the model.

[0093] The speed profile preferably includes the amplitude of the acceleration, the acceleration displacement, the path 13 or a partial region of the path 13 on which the movable furniture part 2 is to be accelerated or driven, the maximum speed and similar parameters. As input parameters, for example, the load of the movable furniture part 2 currently present or the pulse transmission (discrete or continuous) of the operator of the movable furniture part 2 can be used as dynamic parameters.

[0094] By means of the method and in particular the microcontroller 37 or the control and / or regulation device 44, the movement of the movable furniture part 2 can be assisted in its recognition, wherein the movable furniture part 2 can be driven, for example, in the closing direction or the opening direction such that the movable furniture part 2 moves to the end position (closed position or open position 30) substantially noiselessly and / or without exerting great dynamic forces on the structural parts. In general, partial or full drive - in particular over the entire path 13 - to the end position is possible.

[0095] Due to the enhanced functionality of the method compared to the prior art, especially in the case of alternately applying force and / or loading or guiding the movable furniture part 2 with a variable guiding device 3, unexpected and inharmonious movement trajectories can be prevented. Therefore, the speed of the movable furniture part 2 can be prevented from being too fast or too slow, which may cause the movable furniture part 2 to fail to move to the desired end position or result in damage.

[0096] The microcontroller 37 can be understood as a control and / or regulation device 44, or includes a control and / or regulation device as a computing unit.

[0097] Figure 6 It is shown that the electric drive device 6 includes a plurality of lighting devices 31 fixed relative to the fixed furniture part 1. Usually, only one lighting device 31 can also be provided. The lighting device 31 is arranged on the electric drive device 6.

[0098] The lighting device 31 is in the form of a lamp 38 designed as an LED lamp and is partially integrated into the housing 47 of the electric drive device 6 within the electric drive device 6.

[0099] Another lighting device 31 exists in the form of a strip lighting device 40 designed as an LED strip and is directly arranged on the electric drive device 6. As shown by the dashed line, another lighting device 31 can also exist in the form of, for example, a planar lighting device 39 provided as an LED surface here. For example, another lighting device 31 can also be indirectly arranged on the electric drive device 6, such as by connecting to the power supply line 32 of the electric drive device 6 (not shown in the figure for clarity).

[0100] The lighting device 31 is oriented on the lower side of the electric drive device 6 such that another movable furniture part 42 can be illuminated by the lighting device 31, where the lighting device 31 is arranged on the electric drive device 6 of the first movable furniture part 41. Generally, alternatively or additionally, the lighting device 31 can be arranged on the electric drive device 6 of the first movable furniture part 41 or the power supply line 32 of the electric drive device 6 such that the first movable furniture part 41 can be illuminated by the lighting device 31.

[0101] Just as in Figure 9 and Figure 10As described in detail, a displacement measuring device 33 is provided, which can be used as an alternative or supplement to the schematically shown motion sensor 43 to detect the relative position of the movable furniture part 2 relative to the fixed furniture part 1, such as the fully or partially open position 30. According to the determined relative position, the lighting device 31 can be activated by the control and / or regulation device 44 or the microcontroller 37. The displacement measuring device 33 and the motion sensor 43 are arranged on the electric drive device 6 and are coupled to the power supply line 32 of the electric drive device 6 and the lighting device 31. Generally, as an alternative or supplement to the displacement measuring device 33 or the motion sensor 43, a distance sensor 50 (see Figure 1b ) can be used to determine the relative position to trigger the lighting device 31. The number of lighting devices 31 is usually arbitrary.

[0102] The lighting device 31 is arranged between the two main body guide rails 4 of the guiding device 3, wherein the strip-shaped lighting device 40 is arranged laterally between the main body guide rails 4 and extends linearly completely between the two main body guide rails 4.

[0103] There is a direct power connection between the two main body guide rails 4, which can be used for the lighting of the movable furniture part 2, wherein the power connection or power supply is guided through one of the two main body guide rails 4 or the rack 9. The electric drive device 6 is fixedly arranged on one of the two main body guide rails 4, and the rack 9 is arranged on the slide rail 5 of the guiding device 3 for continuously transmitting the movement of the gear 17 of the electric drive device 6 to the slide rail 5. The electric drive device 6 and the power supply line 32 for the electric drive device 6 and for the lighting device 31 are fixedly arranged on the guiding device 3 - on the main body guide rail 4.

[0104] The movable furniture part 2 can be forced via the electric drive device 6 by the control and / or regulation device 44 or the microcontroller 37, so that the connection to the main body guide rail 4 has a dual function. The electric drive device 6 is designed to move the movable furniture part 2 at least partially relative to the fixed furniture part 1, wherein the electric drive device 6 includes the lighting device 31 arranged on the electric drive device 6 or the power supply line 32 of the electric drive device 6.

[0105] A method for illuminating a movable furniture part 2 (and, if necessary, another movable furniture part 42) can be explained as follows: Via an electric drive device 6, the movable furniture part 2 is caused to move at least partially automatically relative to a fixed furniture part 1 along a guiding device 3, and a lighting device 31 arranged on the electric drive device 6 or on a power supply line 32 of the electric drive device 6 is activated so that the movable furniture part 2 is illuminated by the lighting device 31, wherein the movable furniture part 2 is moved while the lighting device 31 remains stationary. Specifically, according to the movement of a first movable furniture part 41, another movable furniture part 42 is illuminated by the lighting device 31, wherein the lighting device 31 remains stationary on the electric drive device 6 of the first movable furniture part 41. For this purpose, the relative position of the other movable furniture part 42 can be detected, and according to the determined relative position, the lighting device 31 is activated via a control and / or regulation device 44 or a microcontroller. For example, an algorithm or a computer program product can be stored in the control and / or regulation device 44 or the microcontroller 37, and the algorithm or the computer program product includes instructions which, when executed by a computing unit, cause the computing unit to execute the method by a storage unit in data connection with the computing unit.

[0106] Preferably, light is emitted in the visible wavelength range, and for example, it can be arranged such that the wavelength range and / or intensity of the lighting device 31 can be changed and / or adjusted - if necessary, via the electric drive device 6 or a receiving unit of the electric drive device 6 for configuring the electric drive device 6.

[0107] Generally speaking, alternatively or additionally, light in the infrared range can also be emitted by means of the lighting device 31 for heating, or light in the UV wavelength range - especially the UVC wavelength range - can be emitted for sterilization or disinfection. Thereby, unwanted microorganisms on stored items or surfaces can be removed, or the internal space of the movable furniture part 2 can be adjusted to a desired temperature so that, for example, daily necessities can be irradiated with an adjustable wavelength range of variable intensity - especially in combination with a vacuum drawer and adjustable if necessary. For this purpose, it is particularly suitable to position the fixed electric drive device 6 above the storage space. It can also be considered to set a locking device according to the activation of the lighting device 31.

[0108] In principle, the power supply method of introducing current into the movable furniture part 2 is expensive and complex because the movement of the movable furniture part 2 must be taken into account. However, illuminating the movable furniture part 2 has the advantage that stored items in the movable furniture part 2 - especially in the absence of light conditions or at night - can be clearly identified. Especially when the electric drive device 6 is fixedly arranged on the main body guide rail 4, introducing current via the main body guide rail 4 can also play a dual role, and the energy supplied to the lighting device 31 can be utilized in a particularly advantageous manner.

[0109] Figure 7a shows an electric drive device 6 having an electric motor 7 that can be powered by 230 V, wherein the electric drive device 6 includes a plate-shaped bracket 22 for arrangement on the main guide rail 4 of the guide device 3, wherein the bracket 22 includes an inclined surface 72 that is designed such that the electric drive device 6 can be installed on the main guide rail 4 arranged on the fixed furniture part 1 in the assembled state (in conjunction with Figure 1b , see Figure 6 ) via a pivoting process.

[0110] The electric drive device 6 has a longitudinal direction 27, and the inclined surface 72 of the bracket 22 is oriented at an acute angle between 5° and 30° with respect to the longitudinal direction 27.

[0111] The inclined surface 72 for arrangement on the main guide rail 4 is arranged on the free end 73 of the bracket 22 that projects laterally from the electric drive device 6 and is arranged spaced apart spatially from the electric drive device 6 and the electric motor 7.

[0112] The electric drive device 6 includes two coupling devices 74 on the bracket 22 for connection to the second interface 35 of the main guide rail 4, wherein generally one coupling device 74 is sufficient. One coupling device 74 is in the form of a hook 75 punched out and bent from a metal plate, and another hook 76 is provided on the bracket 22 as a mating support for connecting the electric drive device 6 to the main guide rail 4. For example, a driving part 36 for the pulling-in device 8 or the ejecting device 11 (if necessary, with a push-and-eject function) can be arranged on the other hook 76. The other hook 76 can be used as the second interface 35.

[0113] Another coupling device 74 (similar to the two coupling devices 74 as the hook / other hook 75, 76) exists as a snap connection 71. The other coupling device 74 is designed as a locking projection 81. The electric drive device 6 can be inserted into the main guide rail 4 via the locking projection 81 and the bracket 22 in a translational manner and can be fixed to the main guide rail 4 in a positionally reliable manner via the two hooks during a pivoting process, wherein generally a positionally reliable fixation can already be achieved via the locking projection 81.

[0114] The locking projection 81 can elastically sink into a corresponding recess for fixation during the assembly process - due to laterally additionally provided grooves in the material. An extension can be seen between the hooks 75, 76, which serves as a rotation axis for the rotational movement after translational contact. Usually, fixation can also be achieved, for example, in the sense of a snap connection, by a snap-in strip via a pure translational movement.

[0115] The coupling device 72 in the form of a hook 75 overlaps with the opening 77 of the bracket 22. The opening 77 has a dual function here that is associated with the manufacturing process of the bracket 22, because the opening 77 can be used as a clamping device (for example, for handling or coating) during production. Alternatively or additionally, the opening 77 can generally also be arranged on the body guide 4, where the dual function regarding connection and manufacturing method can also be utilized. The hook 75 passes through the opening 77 of the bracket 22 (or the body guide 4). The electric drive device 6 can generally be arranged on the body guide 4 indirectly via the bracket 22. The bracket 22 can be of a multi-component design. The hook 75 or the locking projection 81 can generally be arranged on the body guide 4 as a kinematic counterstructure. The multi-piece structure of the opening 77 or the bracket 22 is generally not necessary. The opening 77 is preferably located within the body guide 4, and the hook 75 is inserted into this opening, where the opening 77 determines the position of the body guide 4 in the production equipment for the body guide. Another kinematic technique can be associated with the hook 74.

[0116] An exemplary method for retrofitting the electric drive device 6 onto the guiding device 3 in a state where the guiding device 3 is already assembled can be described as follows: Provide the electric drive device 6 for at least partially automatically moving the movable furniture part 2, and install the guiding device 3 on the fixed furniture part 1 (see Figure 1a ), for guiding the movable furniture part 2 relative to the fixed furniture part 1, where if necessary, remove the ejecting device 11, the pulling-in device 8, the driving part 36 for the ejecting device 11, or the driving part 36 for the pulling-in device 8 from the guiding device 3. Then, arrange the electric drive device 6 substantially completely (if necessary, with the front part 23 of the furniture part protruding downward) below the movable furniture part 2 to be moved at the second interface 35 of the body guide 4, and arrange the rack 9 at the first interface 34 of the slide rail 5 for transmitting the power of the electric drive device 6 to the slide rail 5.

[0117] The first interface 34 of the slide rail 5 can generally be given via the pulling-in device 8.

[0118] At the second interface 35, a locking device 69 (schematically shown in dashed lines) for preventing the movable furniture part 2 from moving relative to the fixed furniture part 1 and the driving part 36 for the ejecting device 11 can be arranged. The driving part 36 for the pulling-in device 8 provided in this embodiment is shown in dashed lines at the second interface.

[0119] During the installation of the electric drive device 6 onto the main guide rail 4, the inclined surface 72 reduces the risk of collision with the fixed furniture part 1 or the main guide rail 4, where the electric drive device 6 can be connected as an additional device to an existing guiding device 3. A rack 9 (or equivalent) can likewise be subsequently coupled to the slide rail 9 in order to transfer the movement of the electric drive device 6 to the movable furniture part 2. Thus, the interfaces 34, 35 in combination with the structural parts to be arranged on the interfaces have multiple functions - on the one hand to ensure that the user can easily carry out the retrofitting, and on the other hand to associate a large number of motion technologies that can be flexibly replaced and varied. Thereby, it is possible to avoid providing multiple interfaces for a large number of motion technologies, where each motion technology is connected as an additional device in an easily installable manner. No additional structural space needs to be provided for the installation of the electric drive device 6. In addition, it is beneficial for power supply to the movable furniture part 2 and for fully transferring the motion to the movable furniture 2.

[0120] Related hereto is a second aspect (associated via the synergistic effect of technical effects), which relates to the comfortable and (especially in the sense of the available storage space) resource-saving installation of the electric drive device 6, where - especially via the connection to the main guide rail 4 and / or through an appropriate transmission design and / or the selection of the electric motor 7 - the electric drive device 6 with a compact or narrow design can be installed below the movable furniture part 2. Thus, the depth of the fixed furniture part 1 can be optimally utilized, and a movable power supply is not required.

[0121] Figure 7b Distinguished from Figure 7a is only that the electric drive device 6 is shown in a perspective view.

[0122] The electric motor 7 is arranged inside the housing 47, and in the use position 14 of the arrangement system, the thickness 67 of this housing in the vertical direction 15 is less than 100 mm. A thickness 67 of less than 80 mm can be achieved. The thickness 67 is preferably less than 60 mm (and a thickness of less than 40 mm can also be considered), so that in traditional furniture, the front part 23 of the furniture part extends below the bottom surface of the electric drive device 6.

[0123] Figure 8a It is shown that the electric motor 7 of the electric drive device 6 is in the form of a brushless outer rotor motor 66, where generally a brushed outer rotor motor 66, a disc rotor motor or a rod motor can also be provided. The outer rotor motor and the disc rotor motor have a particularly flat structural type and are therefore preferred.

[0124] The electric motor 7 is connected to a plurality of transmission stages 55 with gears 17 for driving the movable furniture part 2. Via the configuration of the transmission stages 55, the thickness 67 can be further reduced, and other dimensions can also be designed to be compact.

[0125] Figure 8bDistinguished from Figure 8a it is only that the structural components of the electric drive device 6 that are in operative connection with the electric machine 7 are observed from a changed perspective.

[0126] The electric drive device 6 includes a data interface 63 for the wired transmission of at least one digitized data set stored in a storage unit, where the data interface 63 can generally be designed as an alternative or supplement to the radio signal transmission of the digitized data set.

[0127] The electric drive device 6 includes a triggering sensor 59 for activating the electric machine 7 for the closed position of the movable furniture part 2, where the electric drive device 6 includes a housing 47 that has been disassembled in the view, and the triggering sensor 59 is arranged on the housing 47 for contacting the movable furniture part 2 in the use position 14 of the electric drive device 6.

[0128] The triggering sensor 59 includes a tappet 60 and a microswitch 61, and the triggering sensor can be triggered tactilely and electronically via the microswitch 61. As an alternative or supplement, a specially electronically actuated triggering sensor 59 can be provided.

[0129] Figure 9 A displacement measuring device 33 for this arrangement system is shown, where the displacement measuring sensor 33 is designed to determine the position of the movable furniture part 2 relative to the fixed furniture part 1, and the position can be determined unambiguously in the form of the absolute displacement traveled by the movable furniture part 2 relative to the fixed furniture part 1 by the displacement measuring device 33.

[0130] The electric drive device 6 includes an electric machine 7 with a supply voltage of 230 V, which is used to move the movable furniture part 2 relative to the fixed furniture part 1 at least partially automatically, where the displacement measuring device 33 is arranged on the electric drive device 6 or forms an integral part of the drive device 6 in cooperation with the electric machine 7 and is integrated in the housing 47 of the electric drive device 6. However, it is not necessary to be arranged inside the housing 47.

[0131] The movable furniture part 2 can move translationally relative to the fixed furniture part 1 along a guide device 3 on a path 13 between a closed position and an open position 30, and can be driven by the electric drive device 6 over the entire path 13. The displacement measuring device 33 is provided to determine the position of the movable furniture part 2 relative to the fixed furniture part 1, where the relative position can be determined unambiguously via the displacement measuring device 33.

[0132] The displacement measuring device 33 includes a potentiometer 49 in the form of a rotary potentiometer for determining the position, and it has proven to be particularly advantageous to provide a Hall sensor (a magnet combined with a Hall electronic assembly) in the basic electronic assembly. Alternatively or additionally, a distance sensor 50, such as a distance measuring laser, can be provided. The distance sensor 50 can also generally be positioned spatially spaced apart from the electric drive device 6. The displacement measuring device 33 is arranged on the electric drive device 6.

[0133] The absolute displacement is determined starting from a predefined reference position, where the reference position is in the form of the relative position between the movable furniture part 2 and the fixed furniture part 1, which is given as a stop 51 for identifying the end position of the movable furniture part 2 in this embodiment, or the reference position of the electric drive device 6, which is given as the initial position of the gear 17 connected to the electric motor 7 in this embodiment.

[0134] A potentiometer 49 arranged on the electric motor 7 or a speed measuring device 52 integrated in the control and / or regulation device 44 or the microcontroller 35 is provided. The speed measuring device 52 is used to determine the speed of the movable furniture part 2 relative to the fixed furniture part 1, and the movable furniture part 2 can be driven by the electric drive device 6 with a speed profile matching the determined speed of the movable furniture part 2 and / or the determined absolute displacement.

[0135] The control and / or regulation device 44 or the microcontroller 37 can be used to activate the electric motor 7 in the case of a predefined speed determined by the speed measuring device 52 or a predefined absolute displacement determined by the at least one displacement measuring device 33.

[0136] The position in the form of the absolute displacement traveled and the speed are stored at least temporarily in the storage unit as dynamic data sets for model simulation by the calculation unit of the microcontroller 37 or the control and / or regulation unit 44.

[0137] The displacement measuring device 33 includes a first position sensor 53 designed as a sensing wheel and another position sensor 54 also designed as a sensing wheel, and the absolute displacement can be clearly determined via the relative rotational positions of the respective position sensors 53, 54.

[0138] The first position sensor 53 and another position sensor 54 are in the form of a transmission stage 55 of the electric drive device 6, where the transmission stage 55 is not necessary for the drive transmission ratio from the electric motor 7 to the slide rail 5; other transmission stages 55 are used for this purpose. The range of the transmission ratio available for the displacement measuring device 33 is between 1.01:1 and 1.2:1 and can be transmitted via the first sensing wheel. The transmission ratio in the range between 1.2:1 and 2.3:1 can be transmitted between the first sensing wheel and another sensing wheel, and the transmission ratio in the range between 1.5:1 and 2:1 can be transmitted via the first sensing wheel and another sensing wheel.

[0139] The sensing wheels used as the position sensors 53, 54 are designed as gears 17, but these gears are not necessary for the electric drive device 6 to be embedded in the rack 9. The diameter 56 of the first sensing wheel is different from the diameter 56 of the second sensing wheel, and the absolute displacement not exceeding 1200 mm can be clearly determined by the displacement measuring device 33.

[0140] Starting from the reference position, the absolute displacement of the movable furniture part 2 is determined via the sum or difference of the rotation angles of the two position sensors 53, 54, so that the distance between the movable furniture part 2 and the fixed furniture part 1 can be clearly calculated.

[0141] The displacement measuring device 33 includes a magnetic support 57 passing through the housing 47 of the electric drive device 6 and a plastic part 58. The plastic part 58 has a dual function and can be used as the circuit board of the microcontroller 37.

[0142] The displacement measuring device 33 includes a tactile trigger sensor 59 in the form of a tappet 60 and a microswitch 61. Usually, other trigger sensors 59 that do not require mechanical triggering can also be provided, so that the front gap between the movable furniture part 2 and the fixed furniture part 1 is avoided in the closed position for overvoltage action for electronic triggering, and thus beautiful-looking furniture can be made. For example, pure electronic triggering can be achieved by contacting the movable furniture part 2, where, for example, the pressing or wiping of the front part 23 of the furniture part by the user of the movable furniture part 2 is detected.

[0143] The displacement measuring device 33 and the electric drive device 6 are fixedly arranged together on the main body guide rail 4, where the electric drive energy is transmitted by the movement to the rack 9 arranged on the slide rail 5 so as to be able to transmit the acting force in the entire path 13 or in a partial area of the path 13 starting from any point along the path 13.

[0144] The displacement measuring device 33 is arranged completely indirectly under the movable furniture part 2 in the use position 14 of the arrangement system on the main guide rail 4 via the electric drive device 6. If necessary, the furniture part front 23 of the movable furniture part 2 can extend under the electric drive device 6 or the displacement measuring device 33 in order to, for example, reach the trigger sensor 59. However, at least the bottom of the movable furniture part 2 is arranged above the electric drive device 6.

[0145] Both of the two gears 17 for determining position or speed have microchips. The other gear 17 transfers the energy of the electric motor 7 to the rack 9.

[0146] The electric drive device 6 is arranged on the guide device 3 and is at least non - contacting with the movable furniture part 2 when beside the closed position of the movable furniture part 2.

[0147] Reference Figure 10 An exemplary method of moving the movable furniture part 2 at least partially along a path 13 of the movable furniture part 2 between the closed position and the partial or fully open position 30 of the movable furniture part 2 relative to the furniture part 1 via the electric drive device 6 and the displacement measuring device 33 will be explained: The position of the movable furniture part 2 relative to the fixed furniture part 1 is clearly determined via the displacement measuring device 33 as the absolute displacement traveled by the movable furniture part 2 relative to the fixed furniture part 1, and the movable furniture part 2 is translated between the closed position and the open position 30 along the guide device 3 in a partial area of the path 13 via the electric drive device 6 according to the absolute path determined by the displacement measuring device 33. Through the continuous coupling between the rack 9 and the electric drive device 6, the slide rail 5 can usually be driven over the entire path 13, but this is not absolutely necessary.

[0148] In this method, the absolute displacement, which is the distance between the movable furniture part 2 (usually the slide rail 5) and the fixed furniture part 1 (usually the main guide rail 4), can be clearly determined starting from a predefined reference position via the relative positions of the position sensors 53, 54 and the sum or difference of the rotation angles of the sensors 53, 54 starting from the reference position.

[0149] The movable furniture part 2 can be driven via the control and / or regulation device 44 or the microcontroller 37 with a speed profile adapted to the determined speed or the determined absolute displacement, wherein the electric drive device 6 is activated in the case of a predefined speed or a predefined absolute displacement. For example, an algorithm or a computer program product can be stored, which includes instructions that, when executed by a computing unit, cause the computing unit to execute the method by a storage unit in data connection with the computing unit.

[0150] By means of the displacement measuring device 33 and in particular by means of this clearly determinable relative position between the fixed furniture part 1 or the body guide 4 and the movable furniture part 2 or the slide 5, it is ensured that even after a power failure or other problems, the position of the movable furniture part 2 along the guide device 3 on the path 13 can be clearly determined. Without a reference run, the absolute displacement covered can be clearly calculated, whereby normal operation can be ensured, in particular ensuring a drive matched to the position in a particularly failure-proof manner.

[0151] Furthermore, it can be correctly recognized via the determined position whether the electric drive device 6 should act on the movable furniture part 2 in the direction of the closed position or the open position 30. For example, it can be determined according to the said position and if necessary via the speed whether the operator of the movable furniture part 2 intends to move the movable furniture part 2 in the idling range or wishes to drive the movable furniture part in the closing direction or the opening direction. Furthermore, the speed curve transmitted to the movable furniture part 2 can be matched such that a separate speed can be transmitted for any position along the guide device. The said position can provide additional information as to whether the movable furniture part 2 can move freely (if necessary, bidirectionally) in the idling range or should be driven by the electric drive device (in the closing direction or the opening direction), and to what extent the force application is achieved, or at what speed curve the movable furniture part 2 should be moved.

[0152] Figure 11 and Figure 12 shows the structural components of the electric drive device 6, where in Figure 11 in the enlarged detail view, the protective body 78 integrated in the housing 47 can be seen, which protects the transmission - in particular the transmission stage 55 - from wear by the belt (the drive belt 79).

[0153] Figure 12 The belt drive connected to the electric motor 7 is shown enlarged, where two belt tensioners 80 are provided, which transmit a favorable tension for driving the electric drive device 6. Generally speaking, it is also possible to provide only one belt tensioner 80 or multiple belt tensioners 80, and it has proven particularly advantageous to arrange two belt tensioners 80 on opposite sides of the drive belt 79.

[0154] Figure 13a shows the transmission stage 55 of the electric motor 7, where the electric motor 7 is coupled to the idling clutch 29.

[0155] The electric motor 7 can generally include an overload protection clutch 68, which is only shown schematically in dashed lines because it is not an absolutely necessary separate structural component.

[0156] Figure 13b and Figure 13aThe difference lies only in the viewing direction.

[0157] Figure 14a and 14b shows an overrunning clutch 29 as a structural component including two gears 17, which can act as a transmission stage 55. The overrunning clutch 29 is generally not self-locking.

[0158] The technical details of such an overrunning clutch 29 - especially a helical spring overrunning clutch - can be learned from EP 2 086 372 B2.

[0159] Since the overrunning clutch 29 is integrated into the electric drive device 6, the overrunning clutch 29 can be fixedly positioned on the main guide rail 4.

[0160] Specifically, the electric drive device 6 includes an overrunning clutch 29, via which the movable furniture part 2 can be decoupled from the drive via the motor 7 along the path 13 in the closing direction and the opening direction - for example, according to the speed of the movable furniture part 2 or the position of the movable furniture part 2. By means of the overrunning clutch 29, the movable furniture part 2 can be moved in the overrunning area between the open position 30 and the closed position - for example, according to the force applied to the movable furniture part 2 - in a manner decoupled from the drive by the electric drive device 6, or can be driven by the electric drive device 6 on the path 13 (usually in a partial area of the path 13).

[0161] Generally, an overload protection clutch 68 can also be provided, which - for example, according to the speed of the movable furniture part 2 or the position of the movable furniture part 2 - realizes the decoupling between the motor 7 and the rack 9; due to the double separable connection of the rack 9 (the separable connection between the support device 10 and the rack 9 and the pulling-in device 8) acting as an overload protection clutch 68 when the gear 17 of the electric drive device 6 is engaged, the integrated overload protection clutch 68 can be omitted. Generally, it may be sufficient that only the rack 9 is detachably arranged on the support device 10 or only the support device 10 is detachably arranged on the pulling-in device 8.

[0162] Figure 15 shows the electric drive device 6 arranged on one side of the guiding device 3, wherein another trigger sensor 65 (schematically shown in dashed lines) for activating the motor 7 for the closed position of the movable furniture part 2 arranged on the fixed furniture part 1 (activated in the closed position or via the closed position, and if necessary, activated in the over-pushed position) is fixedly arranged on the second furniture panel 64 via the main guide rail 4 arranged on the second furniture panel 64.

[0163] The further triggering sensor 65 preferably includes a damping device 12 or a buffer. The further triggering sensor 65 can be in a data connection with the electric drive device 6 via a radio connection or a cable connection. Due to this further triggering sensor 65, there is no need to process the front part 23 of the furniture part. The further triggering sensor 65 preferably interacts with the triggering sensor 59.

[0164] The arrangement system includes a stabilizing device 70 for laterally stabilizing the movable furniture part 2 along the guide device 3. Usually, sufficient lateral stability can be generated by the movable furniture part 2 itself. It is conceivable to connect the stabilizing device 70 to the second interface 35 (see Figure 7a ).

[0165] Two additional racks 19 are arranged on the guide device 3, and these two additional racks are arranged on two body guide rails 4. Among them, a synchronizing rod 20 is arranged between the two additional racks 19 for laterally stabilizing the two additional racks 19. The teeth 18 of these additional racks 19 are oriented upwards in the vertical direction 15 and are orthogonal to the orientation of the teeth of the rack 9, although this is not mandatory.

[0166] The synchronizing rod 20 together with the two additional racks 19 can be provided as a separate configuration as an additional device, and at least one of the three structural components can be connected to the second interface 35, the rack 9, the body guide rail 4 or the electric drive device 6.

[0167] There is a direct power connection (schematically shown as a dotted line) between the two body guide rails 4. The power supply line 32 for the motor 7 can be guided by the body guide rail 4 or the rack 9 to supply power to the ejecting device 11, for example.

[0168] As schematically shown on the left side of the view, the rack 9 can include a coupling device 25 by means of which the rack 9 can be extended via a rack extension 26, and then the rack 9 consists of at least two rack segments 28 in the longitudinal direction 27. Thus, a rack 9 with an adjustable length can be provided so that the size of the rack 9 can be adjusted respectively according to the size of the guide device 3 or the pulling-out distance along the path 13. It is also usually conceivable to design the rack 9 to be telescopic.

[0169] Figure 16 A graph is shown with the sensor angle (in degrees) plotted on the ordinate and the absolute displacement along the path 13 (in mm) plotted on the abscissa. With the help of two position sensors 53, 54, the position of the slide rail 5 or the movable furniture part 2 along the path 13 can be clearly identified by the relative rotational position.

[0170] In the diagram, a sensor angle intersection corresponding to a pull-out length of approximately 245 mm is marked with a square, where the intersection 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 is 36°, thereby clearly defining the position. Another sensor angle intersection corresponding to a pull-out length of approximately 165 mm is marked with a circle, where the intersection corresponds to two complete rotations of the first position sensor 53 and five complete rotations of the second position sensor 54. The difference in the rotation angles is 144°, thus clearly defining the position.

[0171] In the present embodiment, based on the fact that up to six rotations are required to clearly determine the position, the signal tolerance of the first position sensor 53 is equal to 60°. Similarly, based on up to 10 rotations, the signal tolerance of the second position sensor 54 is equal to 36°. Combined, the tolerance of the first position sensor 53 can be reduced to + / -30° and the tolerance of the second position sensor 54 can be reduced to + / -18°, and this tolerance is sufficient to accurately determine the absolute displacement via these two position sensors 53, 54. If the transmission ratio is given, optionally in the case where path 13 is longer, redundancy may occur at the intersection for determining the absolute displacement, and this undesirable situation can be eliminated via the data recorded in the storage unit or a different transmission ratio. The use of an auxiliary sensor system can also be considered.
