Description

[Technical Field]

[0001] The present invention relates to an assembly consisting of a container, in particular a drawer, comprising two side walls, a container back wall, and a guide device for moving the container relative to a fixed furniture part, in particular a furniture cabinet, wherein the guide device and / or the container has arranged thereon at least one current interface in a moving connection with the container for supplying energy to at least one current sink. The invention further relates to side walls for the container for such an assembly, in particular mounting strips for the side walls, as well as a container back wall for the container for such an assembly. The invention further relates to furniture and to a method for assembling such an assembly.

[0002] In the furniture field, there is a long-standing need to supply electric current in a suitable manner to drawers or shelves and their drive units. Technical obstacles to overcome in this regard include, inter alia, the problem of a reliable electric current connection in furniture parts that are movable between a closed and an open position, as well as the situation where metal components may endanger the user of the container or damage the container if water penetrates into the container. Storage batteries that can be temporarily charged by induction in the closed position of the container have proven insufficient for the current-technical requirements of furniture.

[0003] Such an assembly is already known from document WO 2022 / 051786, in which an outlet integrated into the rear wall of the container can be supplied with current from a guide device via an outlet connector and a chain bushing.

[0004] The prior art has the disadvantage that assembling the receptacle to the guide device is difficult due to the inaccessibility of the chain bushing when the receptacle is placed in the guide device or in the furniture cabinet, because the receptacle's rear wall conceals the chain bushing and the drawer connector must also be connected in a time-consuming manner with little space for the installer. Similarly, removing the receptacle from the guide device is difficult because there is a risk of irreparably damaging the drawer connector connected to the receptacle's rear wall or the chain bushing connected to the guide device. On the one hand, the assembly and removal process steps are complicated, and on the other hand, numerous manual operations are required to achieve the necessary conductive connection of the socket.

[0005] Furthermore, due to the outlet projecting into the storage space of the container, the power supply for driving the container cannot be used via the guide device and the container's power supply to the outlet itself is limited. Furthermore, the chain bushings are rigidly pre-assembled to the guide device, which, among other things, undesirably increases the required transport volume and increases the risk of damage to the components during transport.

[0006] The technical problem addressed by the present invention is therefore to provide an improved assembly, side wall, rear wall of the container and an improved method compared to the prior art, in which the drawbacks of the prior art are at least partially eliminated and which are particularly advantageous for a comfortable assembly of the container to the guide device and for a multifaceted transmission of current from a current source arranged on a fixed furniture part to the container and / or the guide device.

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

[0008] Therefore, according to the invention, at least one current interface is arranged in the use position of the assembly behind the rear wall and / or the side wall of the container, preferably behind the end face of one of the two side walls of the container, the at least one current interface is arranged on the guide device such that, when the container is assembled or disassembled from the guide device, the container can be conductively coupled or decoupled to the at least one current interface automatically upon alignment of the at least one current interface; and / or It is specified that the at least one current interface has at least one magnet or magnetic contact that can conductively connect the at least one current sink to a current source of a fixed furniture part.

[0009] This makes it possible for the first time to significantly facilitate the assembly of the assembly, in particular of the container and the electric motor of the drive unit, since the installer of the assembly can comfortably place the container on the guide device and move it in the direction of the current interface so that the conductive connection between the current source and the current sink arranged on the container is automatically formed. Preferably, the joining direction of the container is along the guide device and parallel to (oriented opposite to) the coupling direction of the at least one current interface. Likewise, the container can be removed from the guide device through a one-time manual operation, and the conductive connection via the at least one current interface is then automatically released—without the need for intervention by the furniture user.

[0010] Furthermore, the positive property is obtained that an efficient and user-friendly connection of the vessel and / or guiding device to the power grid at the site can be ensured, in which case the current from a current source (generally the power grid) can be transmitted or distributed to various current sinks - for example, a current sink arranged on the vessel, an electric motor of a drive unit, a locking device or a guiding device for the vessel - individually and multilaterally or modularly via at least one current interface.

[0011] For example, a magnetically assisted click connection made via a cable drag chain with a fixed furniture part or a current line guided through the guide device can be connected to a current interface of the guide device by magnetic contact on the rear side of the container, in which case the current can be distributed to a current interface which can optionally be equipped with an electric motor or a locking device (as a current sink of the guide device) and / or to a current interface which can be automatically coupled to the container. Within the container, the current can further be transported to a current sink of the container via a current interface in a side wall or in the rear wall of the container.

[0012] For example, the coupling device of the guide device can be provided with three current interfaces, in which case an electric motor can be arranged on one current interface, a connection to a current source is made via a second current interface, and current is supplied to a current sink of the container via a third current interface. Preferably, at least two current interfaces have different relative orientations to the guide device, for example, one current interface can be oriented upward in the use position of the assembly and another current interface can be oriented perpendicular to it for connection of the container. Advantageously, the conductive connection of the electric motor can be made independently of the conductive connection of the container and / or the connection to the current source (or vice versa).

[0013] Receptacle should be broadly construed to include other movable furniture parts such as shelves or footboards.

[0014] As explained at the beginning, patent protection is also sought for side walls for containers for such assemblies, in particular mounting strips for side walls, which side walls preferably have at least one side wall current interface on their side wall end faces or on their mounting strip end faces, which corresponds to at least one current interface for electrically conductively connecting the side wall to the assembly.

[0015] As explained at the beginning, patent protection is also sought for a container back wall for a container for such an assembly, which container back wall preferably has at least one container back wall current interface at its end face that corresponds to at least one side wall current interface for electrically conductively connecting the container back wall to the assembly.

[0016] The side walls and / or the rear wall of the container distribute current to any location on the container in a visually attractive and efficient manner, especially after the container is assembled, without the need to lay separate current lines inside or outside the container. For example, the side walls can contact and / or already have current lines pre-attached to the front of the container.

[0017] As mentioned at the outset, patent protection is also sought for furniture comprising at least one such assembly, in particular comprising at least one such side wall and / or such a container back wall.

[0018] As mentioned at the outset, patent protection is provided for a method for assembling such an assembly, comprising the following method steps: - providing a side wall, preferably such a side wall, a rear wall of the container, preferably such a rear wall of the container, and a guide device, - a method comprising the step of arranging at least one current interface for supplying at least one current sink on the guide device or on the container in such a way that when the container is moved, the at least one current interface is moved with it and that the at least one current interface is arranged behind the rear wall and / or side wall of the container in the use position of the assembly.

[0019] This allows for particularly efficient mounting of furniture, for example, when an electric motor is inserted or coupled via a magnet to a drive unit for the container arranged on the guide device, and the container is arranged on the guide device to ensure kinematic interaction with the drive unit, and for this purpose separation or connection of current lines is not necessarily required.

[0020] Advantageous embodiments of the invention are defined in the dependent claims.

[0021] It is preferably specified that at least two current interfaces are provided, preferably in the coupling device, and / or that in the use position of the assembly at least one current interface is oriented vertically upwards and at least one current interface is oriented perpendicular thereto, preferably at least three current interfaces are provided.

[0022] This allows one current connection to the current source to be used, on the one hand, for supplying energy to the moving technology of the guide device, e.g., an electric motor, and, on the other hand, for supplying energy to the current sink of the container.

[0023] Preferably, it is specified that at least one current interface is electrically conductively connected to at least one of the two side walls, preferably to a mounting strip of the side wall, and preferably at least one current line is guided through at least one of the two side walls to the front side of the container and / or to at least one current sink, and / or it is specified that a direct current connection between the two side walls occurs particularly preferably via the rear wall of the container.

[0024] This results in particularly good power transfer to the vessel's current sink.

[0025] Preferably, it is specified that the at least one current interface comprises at least one magnet or magnetic contact for removably conductively coupling the at least one current sink to a current source preferably located on a fixed furniture part.

[0026] Therefore, at least one magnet or magnetic contact can have the dual function of position fixing as a coupling part and conductive connection as a connecting part.

[0027] Advantageously, it is specified that the at least one current interface is conductively connected to a current source arranged on a fixed furniture part, preferably via at least one current line and / or cable drag chain, over the entire withdrawal distance of the container along the guiding device.

[0028] The separation from the current source can be carried out in a user-friendly manner via the current interface, in particular via magnetic contacts, or simultaneously or in conjunction with the removal of the mobile technology or container.

[0029] It is preferably specified that the at least one current interface is arranged in a coupling device for an electric motor or a locking device, to which at least one current line and / or cable drag chain, if present, is preferably electrically conductively connected, particularly preferably via at least one magnet or magnetic contact.

[0030] The coupling device can be used for modular coupling and / or position fixing of various mobile technologies in addition to the current sink of the vessel.

[0031] Preferably, the guide device is specified to include two cabinet rails, two drawer rails slidably supported relative to the two cabinet rails, a synchronization rod and / or at least one rack or toothed belt preferably driven by an electric motor of at least one drive unit.

[0032] The synchronizing rod and the rack or toothed belt may generally be assigned to a drive unit.

[0033] It is advantageously specified that the at least one current sink is arranged, preferably directly, on at least one of the two side walls and / or on the rear wall of the vessel and / or is conductively connected, preferably indirectly, to at least one of the two side walls and / or on the rear wall of the vessel via at least one current line.

[0034] The vessel itself may provide current distribution to the current sinks, possibly via current distribution in the coupling device.

[0035] Particularly preferably, it is specified that the rear wall and / or the side wall of the container is arranged on the container, thereby forming an electrically conductive connection between at least one current interface of the coupling device, which is preferably arranged on the guide device, and the rear wall and / or the side wall of the container, preferably from the side wall to the rear wall of the container, and preferably, it is specified that the electrically conductive connection between the at least one current interface and the rear wall of the container is formed by coupling the side wall and / or by pivoting the side wall, particularly preferably the mounting strip, onto the container.

[0036] It is also generally possible to perform a kinematic reversal in conjunction with changing the current interface from the side wall to the vessel back wall.

[0037] Preferably, an electric motor is provided, which is connected to the container in a motion-transmitting manner and is arranged on the container and / or the guide device so as to be removably connectable or connected to a drive unit for the container via a coupling device.

[0038] The electric motor may be modularly arranged on the container as an add-on for the container, indirectly and removably via a coupling device, in which case the current for supplying the electric motor with energy can be diversified and / or the electric motor can be conveniently replaced or retrofitted in existing guide devices / drive units. Removable coupling may be understood as tool-free coupling / discoupling when coupling to the container. Additionally, it is also conceivable to non-removably couple the electric motor to the drive unit.

[0039] For example, the coupling device can be provided with technology as a current sink separate from the electric motor—alternatively or additionally to the electric motor. For example, instead of the electric motor, a locking device can be connected to the container, or a portion of the current flowing through the coupling device from another current sink—e.g., a locking device—can be utilized. Current sinks other than the electric motor can generally be supplied with current that does not flow through the coupling device. Generally, the coupling device can be utilized solely for coupling the electric motor to the drive unit or the container—without directly carrying current.

[0040] This has the positive property that the container can be quickly and simply connected or suspended on the guide system without the need to form a direct current connection to the container, for example the container can be provided with a mounting strip which transfers the current into and / or onto the container, preferably the mounting strip being electrically conductively connected to the coupling device.

[0041] According to an advantageous configuration of the invention, it is specified that the electric motor is arranged in the rear wall of the container and / or behind the rear wall of the container, preferably hidden by the rear wall in the use position of the assembly, and / or that a force can be transmitted by the electric motor via at least one drive unit to the drawer rail of the guide device arranged on the container for relative movement of the drawer rail with respect to the cabinet rail of the guide device.

[0042] The electric motor can be coupled to the container via a drive unit, for example adjacent to the container's rear wall, and can transmit power via a synchronization rod drive to a rack connected to a cabinet rail (fixed to a fixed furniture part), so that - in particular via the container rail - the drawer rail on which the container is arranged is moved relative to the cabinet rail. The container generally does not have to be connected directly or without an intermediate connection to the electric motor or the at least one drive unit, in which case it is preferable to optimally utilize the installation size in order to ideally increase the storage space for the container in a given fixed furniture part.

[0043] When the electric motor is operatively connected to the container and is hidden by the rear wall of the container, the storage space of the container and the space remaining behind the container are not visually impaired by the presence of the electric motor, resulting in a particularly aesthetically appealing piece of furniture.

[0044] The rear wall of the container may generally be provided by a screen which defines the storage space of the container on the rear side, whereby the rear wall of the container does not necessarily have to be the rear wall adjacent to the fixed furniture part.

[0045] Preferably, at least one drive unit stores a physical model of the container and / or the guide device, or calculates such a physical model in an open-loop and / or closed-loop control system. Particularly preferably, at least one drive unit includes at least one sensor system for detecting the speed and / or position of the container along the withdrawal distance. For example, reliable detection of the container's position relative to a fixed furniture part can be achieved by, preferably unambiguously calculating the relative rotation angle of at least two gears and / or rotary potentiometers as sensors. The use of a laser-based distance sensor system is also conceivable.

[0046] In the prior art, synchronizing rods are typically used for stabilization or to prevent tipping or unilateral loading. Preferably, the synchronizing rods are directly driven by an electric motor or are used for direct drive via at least one drive device, which is driven by an electric motor.

[0047] Magnets or magnetic contacts can ensure a fixed positioning of the electric motor in the coupling device of at least one drive unit. Furthermore, the magnets or magnetic contacts can serve a dual function to transmit current to the electric motor or another current sink, so that the coupling device acts, on the one hand, as a fixation for the electric motor and, on the other hand, as a supplier of energy (to the electric motor or an additional current sink).

[0048] An advantageous aspect of the invention is that via the coupling device, preferably via at least one magnet or magnetic contact which may be provided, current can be supplied to the electric motor and / or power can be supplied to at least one current sink which is separate from the electric motor and which is preferably arranged in the container.

[0049] The coupling device can thus have a dual function, in which case it can utilize this dual function or just a power supply for another current sink. The magnetic contacts can form a click connection.

[0050] The cable drag chain ensures that sufficient current line sections are provided for power supply at all positions along the pull-out distance, reducing current line wear. The cable drag chain can be conductively connected to the coupling device by click connections and / or magnetic contacts.

[0051] The current source may typically be located on a fixed piece of furniture or may be located on a cabinet rail or rack.

[0052] In general, the current sink can alternatively or additionally be arranged on the guide device, in which case, for example, lighting means arranged on the drive unit illuminate a further container arranged below the container in the use position of the assembly when this further container is moved from the closed position. The detection of movement can be carried out by a distance measuring device, and it is particularly preferred to use the power supply of the electric motor for the sensor system and / or the lighting means.

[0053] Decoupling of the container from the guide device can preferably be achieved without disconnecting the current connections. Decoupling of the electric motor can preferably be achieved by disconnecting the coupling to the coupling device (without disconnecting the current lines). Decoupling of the guide device can preferably be achieved by disconnecting a similarly shaped coupling to the magnetic connection of the coupling device or a plug-in connection to the current source.

[0054] According to a preferred embodiment of the present invention, at least one current sink comprises: an electric motor for at least one drive unit, and / or - lighting devices, preferably lamps and / or LED strips and / or LED surfaces, and / or - Camera, and / or -Outlet, and / or a charger, preferably wireless, preferably inductive, and / or -locking devices and / or lids for containers, and / or - base steps and / or shelves, and / or sensors and / or data transmission modules, preferably arranged in the side walls of the container; and / or -Temperature control and / or sterilization equipment for containers It exists in the form of

[0055] Sockets and chargers may be understood in the context of the present invention as current sinks even when, for example, no electronic terminal equipment is connected to said socket or charger.

[0056] The camera can, for example, check the condition of the food product - especially in evacuated and / or temperature-controlled and / or sterilized containers - or remotely recognize the contents of the container. The current sink can, for example, be present in the form of a platform or a lid for the container, which can be locked against movement relative to the container or guide device by means of an electric current, or which can be closed substantially airtight.

[0057] By means of a lighting device - in particular integrated into the bottom wall or arranged above the bottom wall - the storage space of the container can be illuminated, for example areas separated by separating means can be individually illuminated.

[0058] The positioning of the at least one current sink is generally arbitrary, with the at least one current sink being particularly preferably arranged directly on the container. The power supply can be conducted, for example, via a guide device, preferably a cabinet rail, and / or by a cable drag chain, or can be distributed from the coupling device. A separate current source, for example, an accumulator or battery, for each current sink is generally not required, and the voltage of the power grid normal in each area, preferably 230 V, can be used.

[0059] Further possible fields of application for the power supply are, for example, container locks for guide devices or the containers themselves, base steps, freshness-keeping lids, etc.

[0060] Preferably, the power supply is conducted via the side wall of the container. For example, the side wall may have a mounting strip for the side wall of the container, which conducts the current from the rear wall of the container to the front side of the container. In this case, the mounting strip may itself include at least one current sink, such as at least one lighting device, and may also have, for example, at least one sensor and / or at least one data transmission module for communicating with electronic means, thereby forming, for example, a product management system. The mounting strip may be electrically conductively connected to the electric motor and / or the coupling device via a click connection and / or magnetic contacts. The mounting strip may be connected to the rear wall of the container via a click connection and / or magnetic contacts.

[0061] A locking device, which can be attached to the coupling device as an alternative or complement to the electric motor, can prevent unauthorized persons from accessing stored items present in the storage space. A locking device as a pad can prevent the movement of a container or prevent access to the storage space. A locking device as a restraining device can be used to fix the position of a shelf in an open position relative to a fixed furniture part. The locking device may generally be used as an anti-vibration device and / or earthquake safety device.

[0062] Via a data interface, for example a data transmission module, information about the movement course of the container or about the contents of the container, or data about the electric motor or the locking device, can be retrieved.

[0063] A current connection between the cabinet rails (or rack or drawer rails) can eliminate current sources connected to both sides of the guide device, in which case energy can be sent directly from one side of the guide device to another side of the guide device.

[0064] By means of the coupling device, both the removal and the installation of the container can be carried out in just one process step. Separate connection of the current cable to the container or the electric motor is not required.

[0067] FIG. 1a shows a piece of furniture comprising an assembly consisting of a container 1 in the form of a drawer and a fixed furniture part - formed as a furniture cabinet.

[0068] The container 1 can be driven by the drive unit 2 from the closed position 38, the open position 39 or a position between the closed position 38 and the open position 39, either completely or only partially towards the open position 39 or towards the closed position 38.

[0069] In FIG. 1 b it can be seen that the container 1 is drivable by an electric motor 4 of a drive unit 2 .

[0070] The electric motor 4 is arranged behind the rear wall 6 of the container 1 and is hidden by the rear wall 6 in the use position 7 of the assembly, in which case the electric motor 4 may be slightly spaced from the rear wall 6. A force can be transmitted from the electric motor 4 via the drive unit 2 to the drawer rail 8 of the guide device 9 arranged on the container 1 for the relative movement of the drawer rail 8 with respect to the cabinet rail 10 of the guide device 9.

[0071] The assembly comprises a drive unit 2 for at least partially automated movement of the container 1 relative to a fixed furniture part 3, an electric motor 4 of the drive unit 2 capable of supplying 230V, and an open-loop and / or closed-loop control device 5 for controlling the electric motor 4.

[0072] The electric motor 4 and the drive unit 2 are arranged on the container 1 via a guide device 9 so that the electric motor 4 is movably connected to the container 1, and the drive unit 2 includes a coupling device 14 for the electric motor 4, via which the electric motor 4 can be detachably coupled to the drive unit 2. The electric motor 4 can be slipped or placed on the drive unit 2 for fixed positioning and is connected via magnetic contacts 15 to a power supply via the drive unit 2.

[0073] The coupling device 14 has magnets in magnetic contacts 15 for fastening the electric motor 4 to the drive unit 2, which magnetic contacts 15 may alternatively or additionally be provided on the electric motor 4.

[0074] A current sink 16 in the form of a lighting device 20 as a lamp is arranged on the front surface 24 of the vessel 1, which is supplied with power via a mounting strip 40 arranged on the upper surface 33 of the side wall 25 of the vessel 1. The power for the lighting device 20 is supplied from the power grid and conducted via a guiding device 9.

[0075] The drive unit 2 is connected to the container 1 so as to be able to transmit force continuously over the entire pull-out distance 11 of the container 1, in which case force can be applied to the container 1 by the drive unit 2 over the entire pull-out distance 11 of the container 1 via the electric motor 4 of the drive unit 2.

[0076] Three exemplary positions for a current sink 16 in the form of a camera 21 are shown diagrammatically on the container 1. The container 1 may have separating means for dividing the storage space or a separate separating means may be arranged on the container 1, in which case the current sink 16 may be arranged on the separating means, which current sink is conductively connected via a current line 17 to the side wall 25 or to the coupling device 14.

[0077] The housing of the electric motor 4 includes a data interface 35, which can transfer digital data sets to a terminal device (e.g., a smartphone) by wireless signal transmission or by wire. The housing of the electric motor 4 includes a memory unit 36 ​​and a calculation unit 37. The memory unit 36, the calculation unit 37 or the data interface 35 can generally be arranged at any position on the drive unit 2, or for example on the side wall 25.

[0078] A current sink 16 in the form of a sensor 45 and a current sink 16 in the form of a data transmission module 46 are arranged on the side wall 25 of the container 1. Another current sink 16 may be provided, for example, as a closable lid for the container, as a base step, or as a shelf. For example, a current sink 16 in the form of a temperature regulator can cool or heat the storage space of the container, and in this case, the current sink 16 as a sterilization device can protect the storage space from contamination or provide a pure atmosphere for the storage space. For example, the temperature regulator (typically each current sink 16) can partially or individually manage the storage space—for example, depending on an open-loop and / or closed-loop control device and / or via a decoupling means.

[0079] A data transmission module 46 and a current sink 16 in the form of a sensor are disposed directly on the side walls 25. A current sink 16 in the form of a camera 21 is conductively connected to the current source indirectly via the rear vessel wall 6. A current sink 16 in the form of a lamp 20 is conductively connected indirectly via a current line 17 to one of the side walls 25 and the rear vessel wall 6.

[0080] 2a shows the area between the mounting strip 40 (possibly spaced from the upper surface 33 of the side wall 25 - mountable or slip-on) and the lighting device 20, with the current wire 17 being guided from the mounting strip 40 of the side wall 25 to a current sink 16 as a lamp on the front surface 24 of the container 24. Typically, the current connection to the lamp can be made outside the front surface 24, with the height of the lamp being adjustable along the front surface 24 relative to the bottom wall 26. The bottom wall 26 defines a cover wall 27 for another container to be placed below the container 1, which cover wall 27 may generally be formed by the fixed furniture part 3.

[0081] Figure 2b shows the vessel 1 including the drive unit 2 with the electric motor 4, with an enlarged detailed partial view of the coupling area of ​​the electric motor 4 to the drive unit 2 and the transmission area of ​​the current coming from the current source. The current transmission can take place via the guide device 9 or via the vessel 1 (side wall 25 or vessel back wall 6).

[0082] 2c, 2d and 2e show the coupling device 14 with the electric motor 4, the coupling device 14 with a locking device 32 alternatively coupled to the electric motor 4, and the coupling device 14 prior to coupling with the desired movement technology for the container. In general, the locking device 32 may be provided in combination with the electric motor 4 or at another location in the assembly. If manual operation of the container 1 is desired, for example, the locking device 32 may be coupled (currently conducting) to the coupling device alternatively to the electric motor 4.

[0083] The coupling device 14 and the current interface 41 are suitable for modularly coupling or conductively connecting a changeable motion technology or current sink 16 to the vessel 1 .

[0084] 2c, it can be seen that the electric motor 4 partially surrounds the side wall 25 in the region of the mounting strip 40 and is connected to the coupling device by magnetic contacts 15 and is electrically conductively connected to the mounting strip 40 of the side wall 25 by magnetic contacts 15. The mounting strip 40 is electrically conductively connected to the rear container wall 6 by magnetic contacts 15, although this is not necessary and current transmission to the side wall 25 can also be omitted. The electrically conductive connection may generally be located away from the magnetic connection.

[0085] In FIG. 2d it can be seen that the current wire 17 is guided from the fixed furniture part 3 via the coupling device 14 for the electric motor 4 or locking device 32 to the locking device 32 (or to the electric motor 4 arranged in the coupling device 14) or via the mounting strip 40 via the side wall 25 of the container 1 to the front surface 24 of the container 1.

[0086] In the use position 7 of the container 1, the current is conducted on the upper surface 33 of the side wall 25 and at least partially on the inside of the side wall 25, with a current connection formed as a plug-in connection being present between the mounting strip 40 of the side wall 25 and the container rear wall 6. When the mounting strip 40 is pivoted towards the storage space of the container, a current connection is established to the second side wall 25 (second mounting strip 40) via the container rear wall 6. The connection process for the current wire 17 is generally optional.

[0087] A locking device 32 of the drive unit 2 is provided for locking the movement of the container 1 relative to the fixed furniture part 3 .

[0088] As shown in Fig. 2e, the coupling device 14 has magnetic contacts 15 through which the electric motor 4 can be arranged on the drive unit 2 and supplied with current. The magnetic contacts 15 or magnets may alternatively or additionally be arranged on the locking device 32 or on the electric motor 4.

[0089] As shown in Figure 2f, the inner current wire 17 of the cable drag chain 18 for providing power guidance sections during movement of the vessel 1 is connected to the side wall 25 and is located below the bottom wall 26.

[0090] The assembly including the two side walls 25 of the container 1, the container rear wall 6 and the guide device 9 is designed in such a way that the guide device 9 provided in the coupling device 14 is provided with one current interface 41 (e.g. for the electric motor 4 or the locking device 32) and the container 1 is provided with four current interfaces 41 for both side walls 25 and for the conductive connections of the container rear wall 6 arranged between the side walls 25. In general, the number of current interfaces 41 for the container 1 is arbitrary, and for example, only the current from the current interface 41 arranged in the coupling device 14 may be transmitted to one of the side walls 25. It is also conceivable to omit the current interface 41 of the coupling device 14 and transmit the current directly to the side walls 25 or the container rear wall 6.

[0091] A current interface 41 is provided for supplying energy to the current sink 16 and is operatively connected to the vessel 1, the current interface 41 being arranged behind the vessel rear wall 6 in the use position 7 of the assembly. Both current interfaces 41 belonging to the side walls 25 are arranged behind the respective side walls 25 at the end sides, and the current interface 41 of the vessel rear wall 6 is arranged adjacent to the side walls 25.

[0092] The current interface 41 is positioned on the guide device 9 such that when the container 1 is assembled or removed from the guide device 9, the alignment of the current interface 41 automatically conductively couples the container 1 to the current interface 41.

[0093] The current interface 41 comprises a magnetic contact 15 by means of which the current sink 16 can be conductively connected to a current source of the fixed furniture part 3 .

[0094] 2g shows a current sink 16 in the form of a socket 22 arranged in the rear wall 6 of the container, which socket protrudes through the rear wall 6. The current for the socket 22 can generally be received from a current source from the coupling point 14, via the side wall 25 or the rear wall 6 of the container, or - possibly guided via a current wire 17 arranged in the guide device 9. From the socket 22, a current wire 17 can generally be led out for transmitting the current to another current sink 16.

[0095] A wireless charger 23 in the form of an inductive charger is shown diagrammatically in Figure 3. However, this area may also be used to illuminate an area of ​​the container 1 via a current sink 16 in the form of, for example, an LED, an LED strip or an LED surface.

[0096] Figure 4a shows the guide device 9 together with the side wall 25 and the rear wall 6 of the container connected to the guide device, in which an enlarged detail fragment shows one of the two racks 13, which may be formed, for example, as a toothed belt.

[0097] In this embodiment, it is specified that two racks 13, arranged parallel and stationary to the cabinet rails 10, connected via a synchronizing rod 12, are provided for synchronizing the movement of the container 1 relative to the fixed furniture part 3 and for lateral stabilization.

[0098] The synchronization rod 12 is driven directly by the electric motor 4 of the drive unit 2, which allows the container 1 to move along the two racks 13. The electric motor 4 (not shown for reasons of clarity) of the drive unit 2 is arranged indirectly on the cabinet rail 10 via one of the racks 13.

[0099] FIG. 4 b shows an enlarged area of ​​the coupling device 14 , whereby when the electric motor 4 is coupled to the drive unit 2 , a power connection to the power system is automatically made via magnetic contacts 15 .

[0100] The current interface 41 of the coupling device 14 is electrically conductively connected to the current interface 41 for the side wall 25, so that current can be transmitted to the lamp 20 via the side wall 25. For this purpose, the mounting strip 40 of the side wall 25 is provided, but this is not necessary. The side wall 25 has, on one side wall end face 42 (here, the mounting strip end face), a side wall current interface 44 that corresponds to the current interface 41 for electrically conductively connecting the side wall 25 to the assembly.

[0101] In general, current can be conducted to the vessel rear wall 6 directly from a current source or indirectly via a current interface 41 of the coupling device 14. In the illustrated embodiment, the current interface 41 of the mounting strip 40 (of the side wall 25) is conductively connected to the current interface 41 of the vessel rear wall 6. For this purpose, the vessel rear wall 6 has vessel rear wall current interfaces on both vessel rear wall end faces 45 that correspond to the side wall current interfaces for conductively connecting the vessel rear wall 6 to the assembly.

[0102] The current wires 17 for the current sink 16 run through the side walls 25 to the front 24 of the vessel 1 and to the current sink 16 located in the vessel. In this embodiment, a direct power connection between the side walls 25 is made via the vessel back wall 6.

[0103] All current interfaces 41 include magnetic contacts 15 for releasably conductively coupling the current sink 16, although this is not necessary. Generally, the current source is located on a fixed furniture part 3.

[0104] The current interface 41 is conductively connected to a current source via a current line 17 or a cable drag chain 18 over the entire drawing distance 11 of the container 1 along the guiding device 9 .

[0105] The current interface 41 of the coupling device 14 is provided for fixing the electric motor 4 or the locking device 32 in position via a magnetic coupling. The coupling device 14 has an additional current interface 41 for electrically conductively connecting to the side wall 25.

[0106] A current line 17 or a cable drag chain 18 is electrically conductively connected to the coupling device 14 via magnetic contacts 15 so that an electric current can be transmitted into the container 1 via the coupling device 14 .

[0107] FIG. 4c differs from FIGS. 4a and 4b only by the extent of the enlarged detail portion.

[0108] The synchronizing rod 12 is in direct contact with the coupling device 14 via the housing and interacts with the electric motor 4 so as to transmit force directly.

[0109] Since the cable drag chain 18 is oriented with its wide side parallel to the synchronizing rod 12 along its longitudinal extension, the assembly is made particularly compact in the vertical direction and the thickness of the cable drag chain 18 can be guided below the synchronizing rod 12, reducing the risk of collision with the synchronizing rod 12.

[0110] The cable drag chain 18 is arranged via magnetic contacts 15 at a current interface 41 of the coupling device 14, whereby the current is transmitted to the current interface 41 for the electric motor (or locking device 32) and to the current interface 41 for the current sinks 16 of the vessel 1 (inside the coupling device 14). The coupling device 14 acts as a current distributor, distributing the current supplied from the current source via the cable drag chain 18 to the different current sinks 16, whereby the vessel 1 generally also acts as a current distributor via another current interface 41.

[0111] In Figure 4d the guide device 9 is shown in the direction of view towards the rear of the container, and in an enlarged detail it can be seen that the coupling device 14 is operatively connected to the container 1 and can be automatically conductively coupled to the current source of the fixed furniture part 3 via the current wires 17 in the cable drag chain 18 when the cable drag chain 18 is conductively connected to the current source of the fixed furniture part 3. It is not necessary for the current source to be directly accessible in order to couple the electric motor 4 or to assemble the container 1.

[0112] The container 1 is removable from or attachable to the fixed furniture part 3 by decoupling or coupling via a coupling device 14 .

[0113] Current lines 17, cable drag chains 18 are connected to and guided on racks 13 along cabinet rails 10. Current sources arranged on fixed furniture parts 3 can be guided generally along cabinet rails 10.

[0114] The coupling device 14 has a current interface 41 for the cable drag chain 18, a current interface for the electric motor 4 (or locking device 32) as well as a current interface 41 for automatic current coupling when the container 1 is assembled.

[0115] In the use position 7 of the assembly, one current interface 41 is oriented vertically upwards and one current interface 41 is oriented perpendicular thereto.

[0116] The side wall 25 has a side wall current interface for coupling to the coupling device 14 for current supply via a current source, and a current interface 41 for coupling to the vessel back wall 6 via the vessel back wall current interface of the vessel back wall 6.

[0117] 4e shows an enlarged view of the cable drag chain 18 including the current conductor 17; typically only one cable drag chain 18 needs to be provided and energy can be supplied to the opposite side of the guiding device 9 via another current conductor 17 as a direct connection. A direct power connection may typically be provided via the synchronizing rod 12.

[0118] 4f shows that the cable drag chain 18 can be detached from the guiding device 9 and is conductively connected to the coupling device 14 to transfer energy to the electric motor 4 from a conductive connection with a current source guided through the guiding device 9. The current source may be stationarily arranged on the fixed furniture part 3. The current source may be formed as a socket or as a plug connection and may also be a magnetic contact 15.

[0119] The coupling device 14 has further magnetic contacts 15 that can transfer power from a current source to the side wall 25, particularly when the mounting strip 40 is coupled thereto. Alternatively or additionally, the side wall 25 can be connected to the magnetic contacts 15 of the electric motor 4.

[0120] FIG. 4 g shows the components that serve for the motion transmission, in order to transform and transmit the force generated by the electric motor 4 via the rack 13 to the drawer rails 8 .

[0121] The synchronizing rod 12 includes two gears 34 that mesh with each of the two racks 13, one of which may be provided for connection to the electric motor 4. However, the structural arrangement of the driven part from the electric motor 4 to the synchronizing rod 12 is generally arbitrary, and may be achieved, for example, via a belt. A gear 34 that meshes with the electric motor 4 is also possible for transmitting power to the synchronizing rod 12. It is also conceivable that the electric motor 4 transmits power to the rack 13 directly or without an intermediary.

[0122] 4h shows that by means of the coupling device 14, current can be supplied to the electric motor 4—via the two magnetic contacts 15—and to the side wall 25 for a current sink 16 (preferably arranged in the vessel 1) separate from the electric motor 4. If the current is transmitted to the side wall 25 (or to the vessel rear wall 6) via the electric motor 4, the magnetic contacts 15 to be assigned to the side wall 25 can be omitted.

[0123] The guide device 9 includes two cabinet rails 10, two drawer rails 8 that can slide relative to the cabinet rails 10, a synchronization rod 12 that is driven by the electric motor 4 of the drive unit 2, and two racks 13, in which case the synchronization rod 12 and the two racks 13 may be assigned to the drive unit 2.

[0124] Figure 4i shows the guide device 9, in this case in an enlarged detailed fragmentary view showing an adapter for the side wall 25 of the container 1 for the power supply. The outlet 22 has been moved away from its position on the guide device 9 for reasons of clarity of the drawing, and the meshing gear 34 is shown on the side of the guide device 9 facing the electric motor 4.

[0125] In the upper right corner of the drawing, the coupling device 14 for the electric motor 4 is shown, and in the upper left corner of the drawing, the connection device for the mounting strip 40 for transmitting power to the side wall 25 and the rear wall 6 of the container is shown.

[0126] Starting from a current source arranged on the fixed furniture part 3, a current line 17 arranged on the container 1 and a current sink 16 arranged on the container 1 are provided, in which case the current line 17 is guided and extends via a cabinet rail 10 arranged on the fixed furniture part 3, and the current line 17 may be connected to the fixed furniture part 3 and extend directly between two cabinet rails 10 or between racks 13.

[0127] An exemplary method for assembling the assembly can be described as follows: a container 1 and a drive unit 2 are provided, with the electric motor 4 being removably arranged via a magnetic connection by slipping it over a coupling device 14 of the container 1, so that the electric motor 4 is movably coupled to the container 1 during relative movement between the container 1 and a fixed furniture part 3. A further current sink 16 of the container can be constantly supplied with current over the extraction distance 11 from a current source arranged on the fixed furniture part.

[0128] The container 1 can be suspended from the fixed furniture part 3 via the guide device 9 in a single assembly step and can be automatically connected to the current source of the fixed furniture part 3. In this case, the container 1 is simultaneously separated from the current source of the fixed furniture part 3 and from the guide device 9 in a single removal process step.

[0129] Another exemplary method for assembling the assembly can be carried out as follows: prepare the side wall 25, the container back wall 6 and the guide device 9, and place the current interface 41 for supplying the current sink 16 on the guide device 9 or on the container such that when the container 1 is moved, the current interface 41 moves with it and the current interface 41 is positioned behind the container back wall 6 or the side wall 25 in the use position 7 of the assembly.

[0130] By coupling the container rear wall 6 or the side wall 25 in the container 1, a conductive connection can be formed between the current interface 41 and the container rear wall 6 or the side wall 25, for example from the side wall 25 to the container rear wall 6. For example, the conductive connection between the current interface 41 and the container rear wall 6 can be formed by coupling the side wall 25, in which case the side wall 25 or the mounting strip 40 of the side wall 25 is pivoted in the container 1. Similarly, the container rear wall 6 can be coupled by pivoting in order to form a conductive connection in the assembly or in the container.
