Field of the Invention

[0001] The present invention relates to an arrangement structure, which includes: a stationary furniture component, in particular a furniture body; a movable furniture component relative to the stationary furniture component, in particular a drawer; and a guiding device, in particular a drawer pull-out guiding device, for guiding the movable furniture component relative to the stationary furniture component, wherein the movable furniture component can move along the guiding device relative to the stationary furniture component on a path, preferably translationally, and wherein at least one electric drive device for causing the movable furniture component to move at least partially automatically relative to the stationary furniture component is provided, and the electric drive device includes at least one motor. In addition, the present invention also relates to a displacement measuring device for such an arrangement structure, an electric drive device for such an arrangement structure, and a method for moving a movable furniture component. The present invention also relates to a computer program product. Background Art

[0002] An arrangement structure including a movable furniture component is known from document EP 1 323 364 A1, in which the drawer is moved by a drive unit controlled by a triggering device. For this purpose, the triggering device includes two push-button switches, such as drag switches, which are arranged on the drawer and can be manually operated, for realizing three different switching states. The triggering device can be activated according to the relative position of the furniture component members or by tapping the furniture component members in order to generate switching pulses.

[0003] An arrangement structure including a movable furniture component is also known from document EP 1 323 363 A1, in which the drive unit is controlled by an adjusting device and a force measuring device in order to automatically support the movement desired by the user of the drawer in both directions. Supplementally, a position measuring device may be present, which generates position signals, and by means of which the instantaneous actual position, actual speed and actual acceleration as a function of the measured position can be calculated. The target value can also be determined, so that substantially the same force consumption can be generated in the case of a changing load of the drawer.

[0004] An arrangement structure including a movable furniture component is also known from document EP 2 642 899 A1, in which different triggering sensitivities can be generated by two sensors when a force is applied to the drawer.

[0005] The disadvantage in the prior art is that in the case of a power failure or other faults, a reference run of the movable furniture component needs to be performed in order to be able to determine the position of the movable furniture, so that appropriate driving can be performed in the direction of the open position or the closed position. Summary of the Invention

[0006] Therefore, the objective technical task of the present invention is to provide an improved arrangement structure compared to the prior art, as well as a displacement measuring device, a drive device, a method, and a computer program product, in which at least some of the deficiencies of the prior art are eliminated, and which is characterized in particular by an especially interference-resistant operation.

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

[0008] Therefore, according to the present invention, it is provided that there is at least one displacement measuring device for determining the position of a movable furniture part relative to a stationary furniture part, wherein the at least one displacement measuring device for ascertaining the position of the movable furniture part along the guide means can ascertain, preferably clearly ascertain, the position of the absolute displacement passed by the movable furniture part relative to the stationary furniture part for the at least one electric drive device.

[0009] Therefore, only through the displacement measuring device and in particular through the clearly determinable relative position between the stationary furniture part or the main guide rail and the movable furniture part or the drawer guide rail, can it be clearly ascertained what position the movable furniture part is in along the path of the guide means even after a power failure or other faults occur.

[0010] The at least one displacement measuring device can be arranged to detect the absolute displacement passed over the entire path, preferably between the fully closed position and the fully open position and / or at least the movement displacement of the movable furniture part along this path caused by the at least one electric drive device.

[0011] Preferably, the at least one electric drive device is activated based on the detection of the absolute displacement passed by the movable furniture part by the at least one displacement measuring device. Particularly preferably, the at least one displacement measuring device is (mechanically if necessary) coupled to the at least one electric drive device.

[0012] In the absence of a reference run, the absolute displacement passed can be clearly calculated, thereby ensuring proper operation and in particular ensuring a drive coordinated with the position. In addition, proper identification can be ensured by the determined position as to whether a force should be applied to the movable furniture part in the direction of the closed position or the open position by the electric drive device. For example, it can be confirmed based on the position and, if necessary, the ascertained speed whether the user of the movable furniture part intends to move the movable furniture part within the free-running area or wishes to drive it in the closing or opening direction.

[0013] Furthermore, it is possible to adapt the speed characteristic curve transmitted to the movable furniture part, so that it is possible to individually achieve an individual speed for any position along the guide device. The position can provide additional information, that is, whether the movable furniture part can move freely (optionally bidirectionally) in the no-load area or should be driven by an electric drive device (in the closing or opening direction), and to what extent force is applied, or at what speed characteristic curve the movable furniture part should move.

[0014] As mentioned at the beginning of the text, a displacement measuring device for such an arrangement is also claimed, wherein the displacement measuring device is configured to determine the position of the movable furniture part relative to the stationary furniture part, and wherein the position in the form of the absolute displacement traveled by the movable furniture part relative to the stationary furniture part can be ascertained, preferably clearly ascertained, by the displacement measuring device.

[0015] As mentioned at the beginning of the text, an electric drive device for such an arrangement is also claimed, wherein the electric drive device includes at least one electric motor for moving the movable furniture part relative to the stationary furniture part at least partially automatically, and wherein at least one such displacement measuring device is provided on the electric drive device.

[0016] As mentioned at the beginning of the text, a method for moving a movable furniture part relative to a stationary furniture part at least partially along a path between a closed position and an open position of the movable furniture part by at least one electric drive device and at least one displacement measuring device is also claimed. The movable furniture part is in particular a drawer, the stationary furniture part is in particular a furniture body, the displacement measuring device is in particular such a displacement measuring device, and the electric drive device is in particular such an electric drive device. In this case, the following method steps are carried out, in particular in chronological order:

[0017] Determine, preferably clearly determine, the position of the movable furniture part relative to the stationary furniture part in the form of the absolute displacement traveled by the movable furniture part relative to the stationary furniture part by means of the at least one displacement measuring device.

[0018] The movable furniture part is moved, preferably translationally, between the closed position and the open position along the guide device, preferably a drawer pull-out guide device, at least in a partial area of the path, according to the absolute path ascertained by the at least one displacement measuring device, by means of the at least one electric drive device.

[0019] As mentioned at the beginning of the text, a computer program product is also claimed, which computer program product comprises instructions, and the instructions, when executed by an arithmetic unit, cause the arithmetic unit to perform such a method from a storage unit that is in a data connection with or can establish a data connection with the arithmetic unit, for example in such a way that an electric drive device is controlled for execution.

[0034] 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 stationary furniture part 1 in the form of a furniture body via a guiding device 3 in the form of a drawer pulling guiding device by an electric drive device 6.

[0035] The movable furniture part 2 can be divided into a first movable furniture part 41 and another movable furniture part 42, wherein the other movable furniture part 42 is arranged below the first movable furniture part 41 in the use position 14 of the arrangement.

[0036] However, the furniture is not limited to drawers and generally also encompasses other containers. For example, the furniture can exist as a furniture body with a baffle, a cabinet with folding doors and / or sliding doors, or the like.

[0037] Figure 1b ​​​A furniture piece with a hidden movable furniture part 2 is shown in the following arrangement structure, which includes a fixed furniture part 1, a movable furniture part 2 that is 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.

[0038] The arrangement structure includes an electric drive device 6 for moving the movable furniture part 2 relative to the fixed furniture part 1 at least partially automatically. The electric drive device includes a motor 7 powered by 230 V. The energy supply for the motor 7 is generally arbitrary and different voltages can also be used. Generally speaking, especially due to regional or local grid characteristics, the voltage may also be lower in order to supply sufficient energy to the motor 7.

[0039] The guiding devices 3 each include a main guide rail 4 provided on the fixed furniture part 1 and a drawer guide rail 5 provided on the movable furniture part 2. Generally, a structural intermediate rail can be at least partially provided between the main guide rail 4 and the drawer guide rail 5, but this is usually - especially also for the full pull-out of the movable furniture part 2 through the previous arrangement structure of the electric drive device 6 and the connection with the rack 9 - not necessary.

[0040] In the detailed view, the connection of the electric drive device 6 to the main guide rail 4 and the connection of the rack 9 to the drawer guide rail 5 are shown enlarged. The drawer guide rail 5 includes a first interface 34 (optionally multiple first interfaces 34), which is suitable for fixing the ejection device 11 and the pulling-in device 8 to the drawer guide rail 5.

[0041] The pulling-in device 8 is provided on the first interface 34 and is usually not necessary. Alternatively or additionally, an ejection device 11 - especially mechanical or electrical - can be provided on the first interface 34. Preferably, the ejection device 11 includes a touch-opening function, by which the ejection process can be triggered through an overpressure movement.

[0042] The main guide rail 4 includes a second interface 35 (optionally multiple second interfaces 35), which is suitable for fixing the driving member 36 for the ejection device 11 or the pulling-in device 8 to the main guide rail 4. The second interface 35 (invisibly in the view) is located on the bottom surface of the main guide rail 4 (see Figure 6 )

[0043] The electric drive device 6 is provided on the second interface 35 and the rack 9 for transmitting force from the electric drive device 6 to the drawer guide rail 5 is provided on the first interface 34.

[0044] The connection of the electric drive device 6 is achieved through a snap connector 71 and through a pivoting process for hooking (see Figure 6). The rack 9 is connected by a snap - on connection 71 during its translational insertion into the pulling device 8 or the drawer guide 5. For example, the snap - on connection 71 may have a snap - in rod or a locking projection 81 (on the rack 9, the pulling device 8 or the drawer guide 5), where, typically alternatively or additionally, it can also be a hook 75. In the embodiment, the rack 9 is connected to the pulling device 8, which may optionally have an ejecting device 11 or may optionally connect the ejecting device 11 to it (alternatives to the pulling device 8 are also conceivable). Similarly, it is also possible for the rack 9 to be directly connected to the drawer guide 5. An indirect connection to the electric drive device 8 (e.g., via a driving member 36 for the pulling device 8) is also possible, where a direct connection is preferred.

[0045] The rack 9 is designed wide enough such that there is a belt (optionally with teeth 18), a rope or the like for force transmission between the electric drive device 6 and the drawer guide 5.

[0046] The electric drive device 6 is arranged on the main guide rail 4 substantially completely below the movable furniture part 2 in the use position 14 of the arrangement structure, where, optionally, the front part 23 of the furniture part (e.g., in order to access the trigger sensor 59) can extend in the vertical 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 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.

[0047] The electric drive device 6 is fixedly mounted on the main guide rail 4 and is always connected to the rack 9 for motion transmission along the entire path 13 of the movable furniture part 2 along the guiding device 3.

[0048] The movable furniture part 2 includes a front part 23 of the furniture part, where 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 structure.

[0049] The electric drive device 6 is arranged flush with the drawer guide 5 or the rack 9 in the closed position. The rack 9 can be used to compensate for the pulling loss (determined by the fastening of the main guide rail and / or by the use of a specific type of trigger sensor).

[0050] The electric drive device 6 is arranged substantially flush with the free end 24 of the main guide rail 4 not only in the closed position but also in the open position 30.

[0051] The stationary furniture part 1 includes two furniture panels 64 that are vertical and oriented parallel to each other in the use position 14, wherein exactly one electric drive device 6 is fixedly mounted on one of the two furniture panels 64 indirectly via the main guide rail 4. Generally speaking, however, additional electric drive devices 6 or additional racks 9 can also be provided on the opposite furniture panel 64, but this is not mandatory.

[0052] The movable furniture part 2 includes a furniture part front 23 in the layout use position 14, wherein the electric drive device 6 on the main guide rail 4 is arranged in the region of the free end 24 of the main guide rail 4 facing the furniture part front 23 (substantially flush with this free end 24 or with the drawer guide 5 in the closed position or with the rack 9 in the closed position).

[0053] Figure 2 The connection of the electric drive device 6 and the main guide rail 4 is shown without the surrounding furniture parts 1, 2, wherein the drawer guide 5 is fully withdrawn on the path 13, and this path serves as the pulling-out path for the movable furniture part 2.

[0054] In the enlarged detail view, the connection of the rack 9 to the drawer guide 5 or the pulling-in device 8 is visible, wherein the ejecting device 11 is shown in dashed lines and is alternatively or additionally provided on the first interface 34. It is also conceivable to provide a locking device 69 on 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 the damping device 12 can also exist as a separate structural component.

[0055] Figure 3 The guide device 3 with the electric drive device 6 is shown for automatically moving the movable furniture part 2 or the drawer guide 5 by means of a motor 7 (which can be powered by 230 V).

[0056] The pulling-in device 8 for the movable furniture part 2 and the rack 9 in operative connection with the electric drive device 6 have been assembled, wherein the pulling-in device 8 is directly arranged on the drawer guide 5 and the rack 9 is indirectly arranged on the first interface 34 of the drawer guide 5 via the pulling-in device 8. Generally, the rack 9 directly contacts the drawer guide 5 alternatively or additionally.

[0057] The rack 9 is detachably arranged on the support device 10 and the support device 10 is detachably arranged on the pulling-in device 8.

[0058] In this context, the detachable connection of the support device 10 refers to a non-violent connection that can preferably be released without tools.

[0059] The support device 10 is arranged horizontally between the rack 9 and the pulling-in device 8 in the horizontal direction 16, where, generally speaking, a rack 9 pointing downward in the vertical direction 15 may also be provided.

[0060] The support device 10 or the pulling-in device 8 may include a mechanical or electrical ejecting device 11, where the pulling-in device 8 includes a damping device 12 for damping the movement of the movable furniture part 2 in the region of the closed position.

[0061] The stationary electric drive device 6 is always connected to the rack 9 along the entire path 13 of the guide device 3 to transmit motion, where the electric drive device 6 includes a gear 17 that meshes with the rack 9 and is connected to the electric motor 7.

[0062] The rack 9 is laterally arranged between the electric drive device 6 and the drawer guide 5 along the entire path 13.

[0063] In this embodiment, exactly one electric drive device 6 is arranged on one of the two main body guides 4 of the guide device 3 and exactly one rack 9 is arranged on one of the two drawer guides 5 of the guide device 3, where, generally speaking, two electric drive devices 6 may also be used on the two main body guides 4.

[0064] The power supply of the electric drive device 6 or, if necessary, an additional current sink (such as Figure 6 the lighting device 31 in

[0065] is realized through the main body guide 4, where, alternatively or additionally, the power supply may be through the rack 9. The power supply can be guided between the two main body guides 4 of the two guide devices 3 provided, in order to supply energy to, for example, another trigger sensor 65. Similarly, each main body guide 4 (or rack 9) can also be powered separately.

[0066] The rack 9 is coupled to the gear 17 of the electric drive device 6. Herein, the rack 9 (either through connection with the support device 10 or by the connection of the support device 10) is bendable (similarly pivotable is also considered) relative to the drawer guide 5 in the horizontal direction 16 and is thus supported with restricted lateral mobility. For example, in the case of the rack 9 with a vertical tooth part 18, it can also be supported in the vertical direction 15 (away from the gear 17) with restricted mobility in the vertical direction 15. Thereby, reliable coupling with the elastic drive device 6 can be achieved. In addition, the assembly effort is reduced due to the reduced tendency of distortion, and the noise generation is reduced due to elastic or flexible deformation. For example, the rack 9 can be pre-tensioned in the direction of the gear 17 by a spring or by its inherent elasticity to ensure form-locking with the electric drive device 6 during operation.

[0067] Particularly preferably, the rack 9 is configured to be flexible to ensure reliable, coordinated, and continuous motion transmission through elastic deformation.

[0068] Due to the detachable connection - especially the double detachable connection - an overload protection clutch can be formed by the participating structural components, whereby the overload protection clutch 68 of the electric drive device 6 can be omitted. For example, in the case of an increase in the load on the rack 9 (such as shaking or applying inappropriate forces to the movable furniture part 2), the tolerance determined thereby in the interaction between the gear 17 and the rack 9 under load can prevent: complete decoupling between the electric drive device 6 and the rack 9 - without losing the utility of the overload protection clutch. Thus, the position of the drawer guide 5 relative to the main guide 4 can still be clearly determined by the relative position between the rack 9 and the gear 17. Decoupling from the motor 7 is not necessary and can be achieved, for example, by an idling clutch 29. The required reference run can be prohibited, where the support device 10 acts as a coupling device.

[0069] Figure 4 An enlarged detail view of the guide device 3 together with the drawer guide 5 in the area of the coupling device on the back of the furniture part for the movable furniture part 2 is shown.

[0070] The drawer guide 5 includes a support device 21 for the rack 9, wherein the support device 21 is provided on the drawer guide 5 and the rack 9. During the relative movement between the drawer guide 5 and the main guide 4, the rack 9 and the support device 21 can pass over the bracket 22 of the electric drive device 6 for connecting the electric drive device 6 to the main guide 4.

[0071] Figure 5 The guide device 3 is shown, wherein the coupling between the gear 17 of the electric drive device 6 in operative connection with the motor 7 and the tooth part 18 of the rack 9 is shown in enlarged detail.

[0072] The electric motor 7 (or the electric drive device 6) includes a gear 17 in the gear stage 55 coupling of the electric drive device 6, which gear meshes with a rack 9.

[0073] The gear 17 is oriented in the horizontal direction 16 in the use position 14 of the arrangement structure in the direction pointing to the drawer guide 5, wherein it is also possible that the gear 17 of the electric drive device 6 is oriented upward in the vertical direction 15.

[0074] The rack 9 is arranged between the electric drive device 6 and the drawer guide 5. The guiding device 3 is in the closed position, wherein the movable furniture part 2 arranged on the drawer guide 5 will be in the end position.

[0075] In order to improve the force transmission degree of the energy transmitted to the movable furniture part by the electric drive device 6 in terms of time and / or intensity, the electric drive device is controlled by a microcontroller 37, which acts as a control and / or regulation device 44 and serves as an arithmetic unit.

[0076] An exemplary method based on an arithmetic unit for moving a movable furniture part 2 relative to a stationary furniture part 1 along a guiding device 3 by means of an electric drive device 6 (for at least partially automatically moving the movable furniture part 2 relative to the stationary furniture part 1 by means of a motor 17) can be implemented as follows: The microcontroller 37 includes an arithmetic unit and a storage unit in a data connection with this arithmetic unit. The microcontroller ascertains a model of the movable furniture part 2 based on 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 based on at least one dynamic data set.

[0077] The static data set can, for example, include the mass of the movable furniture part 2, the friction 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, etc.

[0078] The path 13 usually depends on the pulling-out path of the movable furniture part 2 or the longitudinal extension length of the rack, on which path the electric drive device 6 is at least partially driven by automatic control. Driving can be carried out on the path 13; preferably, driving is carried out on a partial area of the path 13.

[0079] The dynamic data set can for example include the absolute displacement traveled by the movable furniture part 2 relative to the stationary furniture part 1, the speed of the movable furniture part 2, the load in the movable furniture part 2, the acceleration characteristic curve of the movable furniture part 2 (usually ascertained by the speed measuring device 52), the acceleration section of the movable furniture part 2, the kinetic energy of the movable furniture part 2, and so on.

[0080] The static data set and the dynamic data set can be determined during a reference run of the movable furniture part 2 or by means of multiple reference runs - if necessary, in the case of a load change of the movable furniture part 2. Alternatively or additionally, the static data set can be stored in the storage unit without a reference run, and the static data set or the dynamic data set can be compared with the data set stored in the storage unit or corrected based on the stored data set.

[0081] In the present embodiment, the following aspects are specified, but it is not mandatory to implement them:

[0082] The microcontroller 37 makes a decision based on the predicted movement trajectory as to whether the electric drive device 6 should exert a force on the movable furniture 2 or whether the movable furniture part 2 should be made movable manually in the no-load area. The electric motor 7 includes a no-load clutch 29, by means of which the force transmission from the electric motor 7 to the movable furniture part 2 is disengaged in the no-load area.

[0083] 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 ascertained based on the damping power of the damping device 12 provided on the movable furniture part 2 or the stationary furniture part 1.

[0084] The microcontroller 37 defines the speed characteristic curve of the drive of the movable furniture part 2 effected 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 in accordance with the speed characteristic curve. The speed characteristic curve is created 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 power when the speed of the movable furniture part 2 is lower than the speed characteristic curve, and is braked by the electric drive device 6 when the speed of the movable furniture part 2 is higher than the speed characteristic curve, and the force transmission to the movable furniture part 2 is initiated when a predefined speed threshold or a predefined position threshold is reached.

[0085] The microcontroller 37 stores a learning algorithm in the form of artificial intelligence, including a neural network with machine learning or deep learning. The historical predicted motion trajectories are analyzed and compared with each other using the learning algorithm. Based on each static or dynamic data set, the history of the predicted motion trajectories is considered for the future motion trajectory to be predicted, the future speed characteristic curve, or the decision to apply a force to the movable furniture part 2 in the future.

[0086] The motion sequence of the movable furniture part 2 along the guide device 3 is used as training data for artificial intelligence. It has proven to be particularly advantageous to train the learning algorithm using different guide devices 3 and varying force applications or loads on the movable furniture part 2. The motion sequences of the specifically existing guide device and the specific movable furniture part 2 can be added, especially continuously, to the training data for learning purposes.

[0087] The electric drive device 6 remains stationary on the main guide rail 4 during the movement of the movable furniture part 2 and is continuously connected to the rack 9 provided on the drawer guide rail 5.

[0088] The movable furniture part 2 can be driven by the electric drive device 6, from the open position 30 or from a position between the open position 30 and the closed position, along the entire path 13 up to the closed position and the open position 30, or only through a partial area of the path 13. The force application is initiated by the electric drive device 6 in the direction from the closed position to the open position through the overpressure movement of the movable furniture part 2 or by simply electronically triggering the sensor 59. In the no-load area, in the non-driven partial area of the path 13, the movable furniture part 2 can be moved manually, so that the motor 7 does not apply a force to the movable furniture part 2.

[0089] It has proven to be very advantageous that the drive 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.

[0090] The movement of the movable furniture part 2 in the direction of the closed position or the open position 30 can be damped, braked, or stopped by the electric drive device 6. The movable furniture part 2 is forced in the direction of the closed position by the pulling-in device 8 in the area of the closed position. However, the pulling-in device 8 is not absolutely necessary. For example, the pulling-in device 8 can be replaced by the electric drive device 6.

[0091] An algorithm or computer program product including instructions for performing the method can be stored in the microcontroller 37 or the control and / or regulation device 44, transmitted on a data carrier signal, or stored on a data carrier, in particular a non-volatile one.

[0092] The arithmetic unit of the microcontroller 37 or the control and / or regulation device 44 is configured to ascertain 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 the at least one dynamic data set, which may be stored in the storage unit if necessary. The electric drive device 6 includes an arithmetic unit.

[0093] The storage unit has sufficient storage capacity to provide the information required by the model. The arithmetic unit has sufficient computing power to calculate the model with the accuracy required for applications 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 adapted according to the required model accuracy or the accuracy of the output parameters generated by the model, such as the speed profile.

[0094] The speed profile preferably includes the amplitude of the acceleration, the displacement of the acceleration, the path 13 or a partial region of the path 13 on which the movable furniture part 2 should be accelerated or driven, the maximum speed, and the like. As input parameters, for example, the currently present load of the movable furniture part 2 or the pulse transmission (discrete or continuous) of the operator of the movable furniture part 2 can be used as dynamic parameters.

[0095] By this method and in particular by the microcontroller 37 or the control and / or regulation device 44, the movement of the movable furniture part 2 can be assisted in recognition, wherein, for example, the movable furniture part 2 can be driven in the closing direction or the opening direction such that the movable furniture part 2 moves to the end position (closing position or opening position 30) essentially noiselessly and / or without a large force effect on the structural parts. Generally, partial or full drive, especially over the entire path 13, to the end position is possible.

[0096] Compared with the prior art, the functionality of this method can be enhanced. In particular, in the case of alternating application of forces and / or loading of the movable furniture part 2 or changing guide device 3, unwanted and inharmonious movement trajectories can be prevented, and thus the speed of the movable furniture part 2 can be prevented from being inappropriately high or low, which may cause the movable furniture part 2 to be unable to move to the desired end position or cause damage.

[0097] The microcontroller 37 can be understood as the control and / or regulation device 44, or includes the control and / or regulation device as an arithmetic unit.

[0098] Figure 6 It is shown that the electric drive device 6 includes a plurality of lighting devices 31 fixed relative to the stationary furniture part 1, where usually only one lighting device 31 may also be provided. The lighting device 31 is provided on the electric drive device 6.

[0099] The lighting device 31 exists in the form of a lamp 38, which is configured as an LED lamp, and is integrated in the electric drive device 6, and partially integrated in the housing 47 of the electric drive device 6.

[0100] Another lighting device 31 exists in the form of a strip-shaped lighting device 40, which is configured as an LED strip, and is directly provided on the electric drive device 6. As shown by the dashed line, another lighting device 31 may also exist in the form of, for example, a planar lighting device 39, which is configured as an LED surface light source here. For example, another lighting device 31 may also be indirectly provided on the electric drive device 6, for example, through the connection of the power cord 32 and the power cord 32 of the electric drive device 6 (not shown in the figure for clarity).

[0101] The lighting device 31 is oriented on the bottom surface of the electric drive device 6 such that the other movable furniture part 42 can be illuminated by the lighting device 31, where the lighting device 31 is provided on the electric drive device 6 of the first movable furniture part 41. However, generally speaking, 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 cord 32 of the electric drive device 6 such that the first movable furniture part 41 can be illuminated by the lighting device 31.

[0102] As detailed in Figure 9 and Figure 10 , a displacement measuring device 33 is provided, which can be used as an alternative or supplement to the motion sensor 43 shown in the schematic diagram to detect the relative position of the movable furniture part 2 relative to the stationary 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 adjustment device 44 or the microcontroller 37. The displacement measuring device 33 and the motion sensor 43 are provided on the electric drive device 6 and are coupled to the power cord 32 of the electric drive device 6 and the lighting device 31. Usually, 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.

[0103] The lighting device 31 is arranged between the two body guide rails 4 of the guide device 3, wherein the strip-shaped lighting device 40 is arranged laterally between the body guide rails 4 and extends linearly completely between the two body guide rails 4.

[0104] There is a direct power connection between the two body guide rails 4, which can be used for lighting the movable furniture part 2, wherein the power connection or power supply is guided through at least one of the two body guide rails 4 or the rack 9. The electric drive device 6 is fixedly arranged on one of the two body guide rails 4, and the rack 9 is arranged on the drawer guide rail 5 of the guide device 3 for continuously transmitting the movement of the gear 17 of the electric drive device 6 to the drawer guide 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 guide device 3 - on the body guide rail 4.

[0105] The control and / or adjustment device 44 or the microcontroller 37 can be used to apply a force to the movable furniture part 2 through the electric drive device 6, so that the connection to the body guide rail 4 determines a dual function. The electric drive device 6 is used to move the movable furniture part 2 at least partially relative to the stationary furniture part 1, wherein the electric drive device 6 includes a lighting device 31 arranged on the electric drive device 6 or the power supply line 32 of the electric drive device 6.

[0106] An exemplary method for lighting the movable furniture part 2 (optionally another movable furniture part 42) can be explained as follows: The movable furniture part 2 is moved at least partially automatically relative to the stationary furniture part 1 along the guide device 3 by the electric drive device 6, and the lighting device 31 arranged on the electric drive device 6 or the 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 the 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 another movable furniture part 42 can be detected, and according to the determined relative position, the lighting device 31 is activated through the control and / or adjustment device 44 or the microcontroller. For example, an algorithm or a computer program product can be stored in the control and / or adjustment device 44 or the microcontroller 37, and the algorithm or the computer program product includes instructions, and when the instructions are executed by the arithmetic unit, the arithmetic unit is prompted to execute this method from the storage unit in a data connection with the arithmetic unit.

[0107] Preferably, light is emitted in the visible wavelength range, where, for example, it can be stipulated that the wavelength range and / or intensity of the lighting device 31 can be changed and / or adjusted - if necessary, by means of the electrical drive device 6 or the receiving unit of the electrical drive device 6 for configuring the structural electrical drive device 6.

[0108] Generally speaking, alternatively or additionally, the lighting device 31 can also emit light in the infrared range for heating or in the UV wavelength range - especially in the UVC wavelength range - for sterilization or disinfection. Thereby, unwanted microorganisms on the stored items or surfaces can be removed, or the internal temperature of the movable furniture part 2 can be adjusted to the desired temperature so that food can be irradiated with variable intensity or adjustable wavelength range - especially in combination with a vacuum drawer and adjustable if necessary. For this purpose, it is particularly suitable to mount the stationary electrical drive device 6 above the cell. A locking device for activating the lighting device 31 can also be considered.

[0109] In principle, the power supply method for introducing electricity into the movable furniture part 2 is both 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 the stored items in the movable furniture part 2 - especially in the absence of light or at night - can be clearly identified. Especially when the electrical drive device 6 is fixedly arranged on the main guide rail 4, introducing electricity through the main guide rail 4 can also serve a dual purpose, making particularly good use of the power supply to the lighting device 31.

[0110] Figure 7a An electrical drive device 6 with a motor 7 powered by 230V is shown, where the electrical drive device 6 includes a plate-shaped bracket 22 for being arranged on the main guide rail 4 of the guiding device 3, and the bracket 22 includes an inclined surface 72, which is configured such that the electrical drive device 6 can be assembled in the assembled state (in combination Figure 1b , see Figure 6 ) on the main guide rail 4 arranged on the stationary furniture part 1 by means of a pivoting operation.

[0111] The electrical drive device 6 has a longitudinal direction 27, and the inclined surface 72 of the bracket 22 forms an acute angle between 5° and 30° with respect to the longitudinal direction 27.

[0112] The inclined surface 72 for being arranged on the main guide rail 4 is arranged at the free end 73 of the bracket 22 protruding laterally from the electrical drive device 6 and is spatially spaced apart from the electrical drive device 6 and the motor 7.

[0113] The electric drive device 6 on the bracket 22 includes two coupling devices 74 for connection to the second interface 35 of the main guide rail 4. Generally speaking, one coupling device 74 is sufficient. One coupling device 74 is in the form of a hook 75 punched and bent from a metal plate. 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 member 36 for the pulling-in device 8 or the ejecting device 11 (optionally with a touch-opening function) can be provided on the other hook 76. This other hook 76 can be used as the second interface 35.

[0114] The other coupling device 74 is a snap connection 71 (similar to the two coupling devices 74 in the form of hooks / another hook 75, 76). This other coupling device 74 is configured as a locking projection 81. The electric drive device 6 can be translationally plugged onto the main guide rail 4 through the locking projection 81 and the bracket 22, and can be reliably fixed on the main guide rail 4 by the two hooks during the screwing-in process. Generally speaking, reliable fixation of the position can be achieved through the locking projection 81.

[0115] During the assembly process, the locking projection 81 can elastically sink into the corresponding notch for fixation - determined by a groove additionally provided on the side in the material. An extension can be seen between the hooks 75, 76, which serves as the axis of rotation for the rotational movement after translational contact. Generally, fixation can also be achieved, for example, by a snap-in rod through a pure translational movement in the sense of a snap connection.

[0116] 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 related to 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 provided on the main guide rail 4, so that the dual function regarding connection and manufacturing method can also be utilized here. The hook 75 passes through the opening 77 of the bracket 22 (or the main guide rail 4). The electric drive device 6 can generally be indirectly arranged on the main guide rail 4 through 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 main guide rail 4 as a kinematic reversal. The multi-piece structure of the opening 77 or the bracket 22 is generally not necessary. The opening 77 is preferably located in the main guide rail 4, and the hook 75 accesses this opening, where the opening 77 defines the position of the main guide rail 4 in the production equipment of the main guide rail. Other kinematic techniques can be associated with the hook 74.

[0117] An exemplary method for retrofitting an electric drive device 6 onto a guide device 3 in a state where the guide device 3 is already assembled can be described as follows: There is an electric drive device 6 for at least partially automating the movement of a movable furniture part 2, and the guide device 3 is installed on a stationary furniture part 1 (see Figure 1a ), for guiding the movable furniture part 2 relative to the stationary furniture part 1, wherein, if necessary, the ejector device 11, the pulling-in device 8, the driving member 36 for the ejector device 11 or the driving member 36 for the pulling-in device 8 is removed from the guide device 3. Then, the electric drive device 6 is arranged substantially completely (if necessary, with the front part 23 of the furniture part protruding downward) below the movable furniture part 2 to be moved on the second interface 35 of the main guide rail 4, and the rack 9 is arranged on the first interface 34 of the drawer guide rail 5 for transmitting the force of the electric drive device 6 to the drawer guide rail 5.

[0118] The first interface 34 of the drawer guide rail 5 can usually be provided by the pulling-in device 8.

[0119] A locking device 69 (schematically shown in dashed lines) for preventing the movable furniture part 2 from moving relative to the stationary furniture part 1 and a driving member 36 for the ejector device 11 can be arranged at the second interface 35. The driving member 36 of the pulling-in device 8 provided in this embodiment is shown in dashed lines at the second interface.

[0120] 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 stationary furniture part 1 or the main guide rail 4, wherein the electric drive device 6 can be connected as an additional device to an existing guide device 3. The rack 9 (or an equivalent) can also be subsequently coupled to the drawer guide rail 9 in order to transmit the movement of the electric drive device 6 to the movable furniture part 2. Therefore, the interfaces 34, 35 and the structural components arranged at the interfaces 34, 35 have multiple functions - on the one hand, to ensure that the user can easily perform the retrofitting, and on the other hand, to associate a large number of flexibly replaceable and variable movement technologies. This can avoid setting multiple interfaces for a large number of movement technologies, thereby connecting individual movement technologies as additional devices, which is convenient for installation. There is no need to provide additional structural space for installing the electric drive device 6, which is thus beneficial to the supply capacity of the movable furniture part 2 and facilitates the transmission of movement to the movable furniture 2.

[0121] Related hereto is a second aspect (associated by a synergistic effect of technical effects), which relates to a comfortable and (in particular in terms of the available storage space) resource-saving installation of the electric drive device 6, wherein - in particular by connection to the main guide 4 and / or by an appropriate drive design and / or selection of the electric motor 7 - the compact or narrow-designed electric drive device 6 can be installed under the movable furniture part 2. Thereby, the depth of the stationary furniture part 1 can be optimally utilized, and a movable power supply is not required.

[0122] Figure 7b Distinguished from Figure 7a is only that the electric drive device 6 is shown in a perspective view.

[0123] The electric motor 7 is arranged inside the housing 47, and in the use position 14 of the arrangement structure, the thickness 67 of the 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 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.

[0124] Figure 8a The electric motor 7 of the electric drive device 6 is shown in the form of a brushless outer rotor motor 66, wherein a brushed outer rotor motor 66, a disc rotor motor or a rod motor can generally also be provided. The designs of the outer rotor motor and the disc rotor motor are particularly flat and are therefore preferred.

[0125] The electric motor 7 is connected to a plurality of gear stages 55 with gears 17 for driving the movable furniture part 2. By arranging the gear stages 55, the thickness 67 can be further reduced, and other dimensions can also become more compact.

[0126] Figure 8b Distinguished from Figure 8a is only that the structural components of the electric drive device 6 in operative connection with the electric motor 7 are observed from a changed perspective.

[0127] The electric drive device 6 includes a data interface 63 for wired transmission of at least one digital data set stored in a storage unit, wherein the data interface 63 can generally alternatively or additionally be configured for radio signal transmission of the digital data set.

[0128] The electric drive device 6 includes a trigger sensor 59 for activating the electric motor 7 when the movable furniture part 2 is in the closed position, wherein the electric drive device 6 includes a housing 47 that has been disassembled in the view, and the trigger sensor 59 is arranged on the housing 47 for contacting the movable furniture part 2 in the use position of the electric drive device 6.

[0129] The triggering sensor 59 includes a plunger 60 and a microswitch 61 and can be triggered both haptically and electronically by the microswitch 61. Alternatively or additionally, a triggering sensor 59 that can only be activated electronically may be provided.

[0130] Figure 9 A displacement measuring device 33 for the arrangement is shown, wherein the displacement measuring sensor 33 is used to determine the position of the movable furniture part 2 relative to the stationary furniture part 1, and the displacement measuring device 33 can clearly ascertain the position in the form of the absolute displacement traveled by the movable furniture part 2 relative to the stationary furniture part 1.

[0131] The electric drive device 6 includes an electric motor that can be powered by 230V. The electric motor is used to move the movable furniture part 2 relative to the stationary furniture part 1 at least partially automatically. The displacement measuring device 33 is provided on the electric drive device 6 or cooperates with the electric motor 7, forms an integral part of the drive device 6 and is integrated in the housing 47 of the electric drive device 6. However, it is not necessarily required to be arranged inside the housing 47.

[0132] On the path 13 between the closed position and the open position 30, the movable furniture part 2 can move translationally relative to the stationary furniture part 1 along the guiding device 3 and can be driven by the electric drive device 6 throughout the path 13. A displacement measuring device 33 is provided to determine the position of the movable furniture part 2 relative to the stationary furniture part 1, wherein the relative position can be clearly ascertained by the displacement measuring device 33.

[0133] The displacement measuring device 33 includes a potentiometer 49 in the form of a rotary potentiometer for determining the position. It has been proven particularly advantageous to provide a Hall sensor (a magnet combined with a Hall electronic component) in the basic electronic assembly. Alternatively or additionally, a distance sensor 50 - for example, a rangefinder laser - may be provided. The distance sensor 50 can generally be positioned to be spatially separated from the electric drive device 6. The displacement measuring device 33 is provided on the electric drive device 6.

[0134] 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 stationary furniture part 1 - 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 - given as the initial position of the gear 17 in the connection with the electric motor 7 in this embodiment.

[0135] There is a speed measuring device 52 in the form of a potentiometer 49 provided on the electric motor 7 or integrated in the control and / or regulating device 44 or the microcontroller 35. The speed measuring device 52 is used to determine the speed of the movable furniture part 2 relative to the stationary furniture part 1, wherein the movable furniture part 2 can be driven by the electric drive device 6 with a speed characteristic curve adapted to the ascertained speed of the movable furniture part 2 and / or the ascertained absolute displacement.

[0136] The electric motor 7 can be activated by the control and / or regulating device 44 or the microcontroller 37 in the case of a predefined speed ascertained by the speed measuring device 52 or a predefined absolute displacement ascertained by the at least one displacement measuring device 33.

[0137] The position in the form of the absolute displacement traveled is saved at least temporarily as a dynamic data set and the speed as a dynamic data set in the storage unit for model simulation by the microcontroller 37 or the control and / or regulating unit 44.

[0138] The displacement measuring device 33 includes a first position sensor 53, which is designed as a sensing wheel in the form of a gear 17, and another position sensor 54, which is designed as another sensing wheel in the form of a gear 17, wherein the absolute displacement can be determined unambiguously by the relative rotational positions of the position sensors 53, 54.

[0139] The first position sensor 53 and the other position sensor 54 are in the form of a gear stage 55 of the electric drive device 6, wherein the gear stage 55 is not necessary for the drive transmission ratio from the electric motor 7 to the drawer guide 5; for this purpose, other gear stages 55 are used. The transmission ratio range usable for the displacement measuring device 33 is between 1.01:1 and 1.2:1 and can be achieved by the first sensing wheel. A transmission ratio between 1.2:1 and 2.3:1 can be achieved between the first sensing wheel and the other sensing wheel, and a transmission ratio between 1.5:1 and 2:1 can be achieved by the first sensing wheel and the other sensing wheel.

[0140] The sensing wheels used as the position sensors 53, 54 are designed as gears 17, but the gears are not necessary for the electric drive device 6 to engage in the rack 9. The diameter 56 of the first sensing wheel is different from the diameter 56 of the second sensing wheel, wherein the absolute displacement up to 1200 mm can be determined unambiguously by the displacement measuring device 33.

[0141] Starting from the reference position, the absolute displacement of the movable furniture part 2 is determined by the sum or difference of the rotational angles of the two position sensors 53, 54, so that the distance between the movable furniture part 2 and the stationary furniture part 1 can be calculated unambiguously.

[0142] The displacement measuring device 33 includes a magnetic bearing 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 a circuit board for the microcontroller 37.

[0143] The displacement measuring device 33 includes a tactile trigger sensor 59 in the form of a plunger 60 and a microswitch 61. Other trigger sensors 59 that do not require mechanical triggering can usually also be provided, so that in the closed position for the overvoltage movement of the electronic trigger, the front gap between the movable furniture part 2 and the fixed furniture part 1 is avoided, and thus furniture with a particularly delicate appearance can be produced. For example, by contacting the movable furniture part 2, pure electronic triggering can be achieved, 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.

[0144] The displacement measuring device 33 and the electric drive device 6 are fixedly arranged together on the main guide rail 4, wherein the electric drive energy is transmitted to the rack 9 arranged on the drawer guide rail 5 so as to be able to cause the transmission of force over the entire path 13 or from any point along the path 13 within a certain partial area of the path 13.

[0145] The displacement measuring device 33 is completely arranged indirectly below the movable furniture part 2 in the use position 14 of the arrangement structure on the main guide rail 4 through the electric drive device 6. If necessary, the front part 23 of the furniture part of the movable furniture part 2 can extend below the electric drive device 6 or the displacement measuring device 33, for example, to contact the trigger sensor 59. However, at least the bottom plate of the movable furniture part 2 is arranged above the electric drive device 6.

[0146] Both of the two gears 17 for determining the position or speed have microchips. The other gear 17 transmits the energy of the motor 7 to the rack 9.

[0147] The electric drive device 6 is arranged on the guiding device 3 without contact with the movable furniture part 2 at least when it is beside the closed position of the movable furniture part 2.

[0148] Reference Figure 10An exemplary method for moving a movable furniture part 2 at least partially along a path 13 of the movable furniture part 2 between a closed position and a partial or fully open position 30 of the movable furniture part 2 relative to a furniture part 1 by means of an electric drive device 6 and a displacement measuring device 33 will be explained: The position of the movable furniture part 2 relative to the stationary furniture part 1 is clearly determined by the displacement measuring device 33 as the absolute displacement traveled by the movable furniture part 2 relative to the stationary 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 certain partial area of the path 13 by means of the electric drive device 6 according to the absolute path ascertained by the displacement measuring device 33. By means of a continuous coupling between the rack 9 and the electric drive device 6, the drawer guide 5 can generally be driven over the entire path 13, but this is not necessarily required.

[0149] In this method, the absolute displacement, which is the distance between the movable furniture part 2 (usually the drawer guide 5) and the stationary furniture part 1 (usually the main guide 4), can be clearly ascertained from the relative positions of the position sensors 53, 54 starting from a predefined reference position and from the sum or difference of the rotational angles of the sensors 53, 54 starting from the reference position.

[0150] The control and / or regulation device 44 or the microcontroller 37 can be adapted to drive the movable furniture part 2 according to the ascertained speed or the speed characteristic curve of the ascertained 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 algorithm or computer program product includes instructions that, when executed by an arithmetic unit, cause the arithmetic unit to execute this method from a storage unit in data connection with the arithmetic unit.

[0151] By means of the displacement measuring device 33 and in particular by means of this clearly determinable relative position between the stationary furniture part 1 or the main guide 4 and the movable furniture part 2 or the drawer guide 5, it is ensured that the position of the movable furniture part 2 along the guide device 3 on the path 13 can be clearly ascertained even after a power failure or other problems. Without a reference run, the absolute displacement traveled can be clearly calculated, thus ensuring normal operation, in particular ensuring a position-coordinated drive in a particularly fault-free manner and method.

[0152] Furthermore, based on the determined position, it can be correctly identified whether the electric drive device 6 should apply a force to the movable furniture part 2 in the direction of the closed position or the open position 30. For example, it can be determined based on the position and, if necessary, the speed whether the user of the movable furniture part 2 intends to move the movable furniture part 2 in the no-load area or desires to drive the movable furniture part 2 in the closing or opening direction. Furthermore, the speed characteristic curve transmitted to the movable furniture part 2 can be adapted, so that an individual speed can be transmitted for any position along the guide device. The position can provide additional information on whether the movable furniture part 2 can move freely in the no-load area (which can be two-way if necessary) or whether it should be driven by the electric drive device (in the closing or opening direction), and to what extent the force application is to be achieved, or at what speed characteristic curve the movable furniture part 2 should move.

[0153] Figure 11 and Figure 12 shows structural components of the electric drive device 6, wherein, in Figure 11 the protective body 78 integrated in the housing 47 can be seen in the enlarged detail view, and this protective body protects the transmission - in particular the gear stage 55 - from wear by the belt (the drive belt 79).

[0154] Figure 12 The belt drive connected to the electric motor 7 is shown enlarged, and two belt tensioners 80 are provided, and these belt tensioners transmit a favorable tension for driving the electric drive device 6. Generally speaking, only one belt tensioner 80 or multiple belt tensioners 80 can also be provided, and it has been proven particularly advantageous to provide two belt tensioners 80 on the opposite sides of the drive belt 79.

[0155] Figure 13a shows the gear stage 55 of the electric motor 7, wherein the electric motor 7 and the no-load clutch 29 are coupled.

[0156] The electric motor 7 can generally include an overload protection clutch 68, and this overload clutch is only schematically shown in dashed lines because it is not a mandatory separate structural component.

[0157] Figure 13b and Figure 13a only differ in the viewing direction.

[0158] Figure 14a and Figure 14b shows the no-load clutch 29 which includes two gears 17 as structural components, and these two gears can act as the gear stage 55. The no-load clutch 29 is generally not self-locking.

[0159] Technical details regarding such an idling clutch 29 - in particular a helical spring idling clutch - are known from EP 2 086 372 B2.

[0160] Since the idling clutch 29 is integrated into the electric drive device 6, the idling clutch 29 can be positioned stationary on the main guide rail 4.

[0161] Specifically, the electric drive device 6 includes an idling clutch 29 by means of which the movable furniture part 2 can be decoupled from the drive of the electric motor 7 along a path 13 in the closing direction and the opening direction - for example depending on the speed of the movable furniture part 2 or the position of the movable furniture part 2. By means of the idling clutch 29, the movable furniture part 2 can move in the no-load area between the open position 30 and the closed position - for example depending on the force applied to the movable furniture part 2 - decoupled from the drive of the electric drive device 6, or be driven by the electric drive device 6 on the path 13 (usually a partial area of the path 13).

[0162] Generally, an overload protection clutch 68 can likewise be provided, which - for example depending on the speed of the movable furniture part 2 or the position of the movable furniture part 2 - effects decoupling between the electric motor 7 and the rack 9; due to the double detachable connection of the rack 9 (detachable connection between the support device 10 and the rack 9 and between the pulling-in device 8), when the gear 17 of the electric drive device 6 engages, it acts as an overload protection clutch 68, and an integrated overload protection clutch 68 can be dispensed with. Generally, it may already be sufficient if 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.

[0163] Figure 15 An electric drive device 6 is shown arranged on one side of the guide device 3, wherein another trigger sensor 65 (schematically shown in dashed lines) for activating the electric motor 7 in order to bring the movable furniture part 2 arranged on the stationary furniture part 1 into the closed position (activated at or by the closed position, optionally activated over-travel position) is fixedly arranged on the second furniture panel 64 by means of the main guide rail 4 arranged on the second furniture panel 64.

[0164] Another trigger sensor 65 preferably includes a damping device 12 or a buffer. This another trigger 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 another trigger sensor 65, it is not necessary to process the front part 23 of the furniture part. This another trigger sensor 65 preferably acts in conjunction with the trigger sensor 59.

[0165] The arrangement includes a stabilizer device 70 for laterally stabilizing the movable furniture part 2 along the guide device 3. Usually, the movable furniture part 2 itself can generate sufficient lateral stability. It is contemplated to connect the stabilizer device 70 to the second interface 35 (see Figure 7a ).

[0166] Two additional racks 19 are arranged on the guide device 3, and the two additional racks 19 are provided on the main body guide 4. Among them, a synchronizing rod 20 is arranged between the two additional racks 19 for laterally stabilizing the two additional racks 19. The tooth portions 18 of the additional racks 19 are oriented upward in the vertical direction 15 and are orthogonal to the orientation of the teeth of the rack 9, which is not mandatory.

[0167] The synchronizing rod 20 together with the two additional racks 19 can be arranged separately 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 main body guide 4 or the electric drive device 6.

[0168] There is a direct power connection (shown in dashed lines) between the two main body guides 4. The power supply line 32 for the motor 7 can be guided by the main body guide 4 or the rack 9 to supply power to the ejecting device 11, for example.

[0169] As schematically shown on the left side of the view, the rack 9 can include a coupling device 25 through which the rack 9 can be extended by a rack extension 26. 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 according to the size of the guide device 3 or the pulling-out distance along the path 13, respectively. It is also usually contemplated to design the rack 9 to be telescopic.

[0170] Figure 16 A graph showing the sensor angle (in degrees) plotted on the ordinate and the absolute displacement (in mm) along the path 13 plotted on the abscissa is shown. Through the two position sensors 53, 54, the position of the drawer guide 5 or the movable furniture part 2 on the path 13 can be clearly identified by the relative rotational position.

[0171] In the graph, an intersection point of the sensor angle corresponding to a pulling-out length of about 245 mm is marked with a square, where 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 between the rotation angles is 36°, which clearly defines the position. Another intersection point of the sensor angle corresponding to a pulling-out length of about 165 mm is marked with a circle, where this intersection point corresponds to two complete rotations of the first position sensor 53 and five complete rotations of the second position sensor 54. The difference between the rotation angles is 144°, thus clearly defining the position.

[0172] In this embodiment, based on the fact that it takes at most six rotations to definitely determine the position, the signal tolerance of the first position sensor 53 is equal to 60°. Similarly, based on at most 10 rotations, the signal tolerance of the second position sensor 54 is equal to 36°. Combined, the tolerances can be reduced to + / -30° and + / -18° respectively for the first position sensor 53 and the second position sensor 54, and this tolerance is sufficient to accurately determine the absolute displacement through the two position sensors 53, 54. If the transmission ratio is given, intersections for finding the absolute displacement may be redundant in the case of a longer path 13, and this undesirable situation can be eliminated by entries in the storage unit or a changing transmission ratio. The use of additional sensors can also be considered.
