Description

[0001] Furniture with cable drive device

[0002] The invention relates to a piece of furniture, comprising a furniture body, at least one door arrangement, comprising a revolving door, folding door and / or folding sliding door, preferably pivotable about an axis that is vertical in the position of use of the furniture, for at least partially covering the furniture body, preferably an interior space of the furniture body defined by the furniture body, in a closed position of the at least one door arrangement and at least one cable drive device. Furthermore, the invention relates to a method for moving a door arrangement of a piece of furniture by means of at least one cable drive device, which is coupled by at least one cable to the door arrangement comprising a revolving door, folding door and / or folding sliding door.

[0003] Such a piece of furniture is already known from the document DE 20 2020 107 104 Ul, in which a rope of a mechanical rope drive device is arranged via balls on a support of a door arrangement in order to support the extension of a support from a receiving shaft.

[0004] A disadvantage of the current technology is that the cable can only impart a translational movement and only in one direction relative to the receiving shaft. All other movement trajectories of the door assembly must be performed manually. Furthermore, a manual application of force is required to move the door assembly.

[0005] The objective technical object of the present invention is therefore to provide a piece of furniture which is improved compared to the prior art, as well as a method in which the disadvantages of the prior art are at least partially eliminated, and which are characterized in particular by an efficient and / or cost-effective drive of the door arrangement, which in particular enables a comfortable movement of the door arrangement with a small number of components and / or low forces to be transmitted to the door arrangement and / or covers movements other than a translational movement of the door arrangement within the receiving shaft.

[0006] This problem is solved by the features of claim 1.

[0007] It is therefore provided according to the invention that the at least one cable drive device comprises at least one electric drive device and at least one cable which can be acted upon by the at least one drive device, wherein the at least one cable is arranged or can be arranged on the at least one door arrangement in such a way that the at least one door arrangement can be moved, preferably

[0008] - starting from the closed position or a partial open position towards an open position, preferably up to the open position, and / or

[0009] - starting from the open position or the partial open position towards the closed position, preferably up to the closed position.

[0010] This makes it possible for a door arrangement to be moved in a user-friendly, fully automatic manner between the closed position and the open position and / or a retracted position next to or in the furniture body and the open position after activation of the at least one cable drive device. In general, it is conceivable that the at least one cable drive device merely reduces the manual effort required to open or close the door arrangement as a support mechanism, or that the at least one door arrangement is only moved in certain areas between the closed position and the open position or the retracted position (generally in a receiving shaft), with a fully automatic and complete movement of the door arrangement by the particularly efficient drive means of the at least one cable in conjunction with the at least one electric drive device being preferred.Manually moving the revolving door, folding door or folding sliding door is no longer necessary to open and close the door assembly.

[0011] The specific connection of the cable to the at least one door assembly is not essential in this regard and can vary for different door assembly types. For example, it has proven advantageous if the at least one cable engages a carriage in a folding-sliding door and interacts with a coupling mechanism in a revolving door. In order to avoid requiring a large number of components and to keep the force acting on the at least one door assembly at a low level, the at least one cable drive device has proven to be an optimal means.

[0012] The specific coupling of the cable to the at least one door assembly can be provided, for example, depending on customer requirements, whereby a particularly favorable power transmission and, resulting in a particularly harmonious movement trajectory and a long service life can be generated by connecting the at least one cable to the carriage. However, if the requirement is for a particularly simple and / or efficient assembly process, the at least one cable can be connected to a support of the door assembly via a coupling gear.What is essential, however, is only that at least one cable of a cable drive device is provided, which interacts with the at least one door arrangement in such a way that the door arrangement is moved by means of electrical energy, preferably in order to enable a movement between the closed position and the open position in addition to a purely translational movement within the receiving shaft separate from the furniture body.

[0013] Another positive feature is that the power transmission can take place continuously without any jerky movements and with particularly low noise levels.

[0014] Tension transmission means such as bands, Bowden cables, belts, chains or the like are encompassed by the term rope in the context of the invention.

[0015] The mechanical transmission of the force from the at least one cable drive device to the at least one door arrangement can be initiated mechatronically.

[0016] Preferably, the opening movement from the closed position and the retraction movement of the at least one door arrangement into a receiving shaft are carried out by means of the at least one cable drive device, and the extension movement and the closing movement are carried out exclusively by means of a mechanical movement mechanism, which is particularly preferably tensioned by the at least one cable drive device. Particularly preferably, the mechanical movement mechanism comprises an ejection device arranged in the receiving shaft and / or a spring device acting between two door leaves and / or arranged (in the open position) for spreading the door leaves, preferably comprising a damping device.

[0017] Particularly preferably, a movement of the at least one door arrangement from a parking position present in the receiving shaft in the direction of the closed position is initiated by a movement of the at least one door arrangement into an over-pressing position located behind the parking position - following a temporary rest of the at least one door arrangement in the parking position - by the at least one cable drive device, wherein preferably an ejection device is tensioned by the movement into the over-pressing position.

[0018] Particularly preferably, the piece of furniture is designed to conceal further pieces of furniture, wherein it is preferably provided that the piece of furniture has a supporting structure for the at least one door arrangement that is independent of the piece of furniture to be covered.

[0019] The closed position can be defined, in the position of use of the furniture, by a coplanar or parallel position of the door assembly to a front of the furniture body. The open position can be defined, in the position of use of the furniture, by a fully folded position of the folding door or folding-sliding door or by a fully unfolded position of the revolving door, in which, in particular, a transfer of the at least one door assembly into the receiving shaft is possible. The transition from the closed position to the open position can be referred to as unfolding or unfolding the at least one door assembly.

[0020] As stated at the outset, protection is also sought for a method for moving a door arrangement of a piece of furniture by at least one cable drive device, which is coupled by at least one cable to the door arrangement comprising a revolving door, folding door and / or folding sliding door, wherein the following method steps are carried out:

[0021] - the door arrangement is moved from a closed position or a partially open position towards an open position, preferably up to the open position, and / or

[0022] - starting from the open position or the partially open position towards the closed position, preferably up to the closed position, and / or - starting from the open position or a partially retracted position towards a retracted position, preferably up to the retracted position, and / or

[0023] - starting from the retracted position or the partially retracted position in the direction of the open position, preferably up to the open position, via which at least one cable drive device is moved by at least one electric drive device of the at least one cable drive device.

[0024] In general, the movement of the door arrangement can be effected entirely by the force imparted via the at least one cable drive device or can be assisted only in addition to a manual application of force to the door arrangement for moving the door arrangement by the at least one electric drive device.

[0025] For example, a piece of furniture with a folding door can be unfolded from the closed position via the at least one cable drive device by the cable engaging a carriage coupled to the folding door, preferably a pivot lever of the carriage temporarily in contact with the folding door, and - initiated by an overpressure movement on the folding door - the drive device is activated in order to move the carriage relative to the furniture body for unfolding. A dead center position of the folding door in the closed position can generally be overcome, for example, by an ejection device or the pivot lever arranged on the folding door in certain areas during the folding process.

[0026] Closing the door assembly—for example, with a revolving or folding door—can be achieved, for example, via an interposed coupling mechanism. Generally, the coupling mechanism can be driven by the cable strand when the door assembly is opened, whereby the door assembly can be closed via an energy storage device. Alternatively or additionally, it is possible to realize the closing process of the door assembly using an energy storage device of a hinge—particularly between door leaves or connected to a support.

[0027] In general, the coupling gear can have its own electric drive device, although this is not absolutely necessary - for example in interaction with at least one toothed rack for moving the at least one door arrangement relative to a receiving shaft of the furniture and / or in interaction with a worm drive of the coupling gear.

[0028] To prevent the door assembly support from undesirably retracting prematurely into a lateral receiving shaft of the furniture, the support can be locked in an extended position by a locking device or by applying sufficient force in the opening direction. In general, in the case of a folding door or folding-sliding door, accidental opening between the open and retracted positions can be prevented by a locking device. The transition from a locked or sufficiently pre-tensioned position of the door assembly can be used to activate the drive device.

[0029] For example, a transition of the support in the direction of the receiving shaft in the presence of a partial closed position can be secured in a form-fitting manner (for example by blocking a movement of a carriage along a guide rail, in particular in the case of a folding door) and / or in a force-fitting manner (for example by requiring a force acting above a threshold value via the at least one cable along the receiving shaft, in particular in the case of a revolving door).

[0030] Advantageous embodiments of the invention are defined in the dependent claims. With a parallel arrangement of the at least one door assembly relative to the receiving shaft, the retraction movement of the carrier can be enabled.

[0031] According to an advantageous embodiment of the invention, it is provided that the revolving door, folding door and / or folding sliding door is arranged, preferably via a hinge strip, on a support and / or at least one carriage of the at least one door arrangement, wherein it is preferably provided that the at least one carriage is translationally movable along a first guide rail between the open position and the closed position and / or the support is translationally movable along a second guide rail, preferably arranged orthogonally to the first guide rail, between the open position and a retracted position laterally next to the furniture body.

[0032] The at least one carriage can act in a dual function, with the movement of the at least one door assembly along the second guide rail only being released upon reaching an end position along a first guide rail, in order to ensure proper retraction of the at least one door assembly into the receiving shaft. The insertion movement into the receiving shaft can also be blocked when using a revolving door, with, for example, the transition into the receiving shaft being blocked until the rotation is complete.Alternatively or additionally, a force-controlled locking of the insertion movement can be provided, in which the at least one door arrangement is pretensioned from the receiving shaft toward the open position, and only when the at least one door arrangement is in the parallel position to the receiving shaft does the cable force of the cable drive device overcome this pretensioning force to move into the receiving shaft. The force-controlled locking is preferably effected by a reduction gear.

[0033] Advantageously, it is provided that the piece of furniture has a receiving shaft laterally next to the furniture body for at least partially receiving the at least one door arrangement in a retracted position, wherein it is preferably provided that the receiving shaft comprises at least one ejection device for ejecting the at least one door arrangement in the direction of the open position, wherein an ejection force accumulator of the at least one ejection device can be loaded by the movement of the at least one door arrangement in the direction of the retracted position mediated by the at least one cable drive device.

[0034] The automatic loading process of the ejector eliminates the need to manually supply energy to an ejection mechanism.

[0035] It has proven advantageous that the at least one drive device is arranged stationary, preferably in a rear region of the receiving shaft, within the receiving shaft and / or is coupled in terms of movement to the at least one door arrangement, preferably to a support which may be present.

[0036] Particularly preferably, the at least one drive device is connected to the support, which can facilitate assembly of the at least one drive device. The at least one drive device (and any coupling gear present) can, however, also be connected, for example, to the first guide rail and / or to the furniture body and / or to a front end of the receiving shaft. For example, the at least one drive device can be used as an add-on for retrofitting existing movement technologies of the furniture, wherein an interface for the at least one drive device can be arranged, for example, on the support and / or in a receiving shaft.

[0037] If the at least one drive device is arranged on the support, a retraction movement of the at least one door arrangement can be brought about, for example, by connecting the at least one cable to a rear region of the receiving shaft or by deflecting the cable on a deflection roller at the rear region of the receiving shaft.

[0038] According to an advantageous embodiment of the invention, it is provided that the at least one door arrangement via the at least one cable drive device

[0039] - starting from an open position or a partially retracted position towards a retracted position, preferably up to the retracted position, and / or

[0040] - is movable from the retracted position or the partially retracted position towards the open position, preferably up to the open position.

[0041] This makes it possible for the same cable drive device to take over the movement both across the front of the furniture body and along the receiving shaft, so that the number of drive concepts can be reduced.

[0042] An advantageous variant of the invention consists in that at least one deflection device for the at least one cable is arranged on the furniture body, preferably on a guide rail that may be present, and / or in a receiving shaft that may be present.

[0043] By means of the at least one deflection device - in particular at least one deflection roller - the at least one drive device can be concealed by a carrier and stowed at the rear in the receiving shaft and / or arranged at a suitable position on the furniture body and yet still generate a force transmission to a free end of the at least one door arrangement, in order in particular to carry out an entire path of the at least one door arrangement with electrical or stored mechanical energy apart from a manual actuation or a jerky ejection movement.

[0044] Preferably, the at least one cable is guided through the at least one deflection device in a loop (without a free end) so that, depending on the direction of rotation, a closing movement or an opening movement of the at least one door arrangement can be mediated via the at least one drive device - preferably via at least one coupling gear.

[0045] It is particularly preferred that the at least one cable is arranged on the at least one carriage and / or the at least one carriage comprises at least one pivoting lever, wherein the at least one pivoting lever is pivotably arranged on the at least one carriage and can be brought into contact with the at least one door arrangement.

[0046] A dead center position in the closed position can be bridged by the at least one pivoting lever. Overcoming the dead center position - for example via an ejection device or by manual actuation - is not necessary due to the interaction between the at least one pivoting lever and the at least one door arrangement. In one embodiment of the invention it is provided that the at least one cable is arranged on the at least one pivoting lever, wherein it is preferably provided that a pivoting movement of the at least one pivoting lever is limited by the at least one carriage, preferably a stop arranged on the at least one carriage and / or in the range between 5 ° and 15 ° door arrangement opening angle.

[0047] By limiting the pivoting path, the cable drive device is prevented from running idle in conjunction with the movement of at least one door assembly. The stop can be provided, for example, by a pin.

[0048] According to a preferred embodiment of the invention, it is provided that the at least one drive device can be activated by a switch, preferably arranged on the furniture body or on the at least one door arrangement, preferably by an overpressure movement of the at least one door arrangement in the closed position and / or by contacting or capacitively.

[0049] By means of the at least one switch, an opening or closing request by the operator of the piece of furniture can be automatically forwarded to the at least one drive device. The switch can be activated by contact with the at least one door arrangement and / or by actuation via an operator of the piece of furniture, wherein the switch can be arranged, for example, on a furniture side wall and / or a horizontally oriented furniture panel and / or on a remote control. Alternatively or additionally, it is possible to initiate a movement of the at least one door arrangement in the direction of the closed position or open position by detecting a change in length (for example due to a movement of the at least one door arrangement from a closed position into an overpressure position lying behind the closed position) of a section of cable projecting from the at least one cable drive device.

[0050] Furthermore, it is preferably provided that the at least one door arrangement is completely foldable and / or foldable or hinged and / or hinged between the closed position and the open position by the at least one cable drive device and / or the at least one door arrangement comprises a folding door or folding sliding door, wherein the folding door or folding sliding door comprises a hinge, wherein the hinge connects door leaves of the folding door or folding sliding door to one another and

[0051] - which is arranged in the closed position or an overpressure position on the at least one cable in such a way that a pre-tension can be imparted to the at least one cable, and / or

[0052] - which comprises a hinge force accumulator for supporting a movement of the at least one door arrangement in the direction of the closed position, wherein the hinge force accumulator can be loaded by the movement of the at least one door arrangement in the direction of the open position mediated by the at least one cable drive device.

[0053] An unfolding or unfolding process can be supported by pre-tensioning at least one rope.

[0054] Due to the automatic charging process of the hinge energy storage device, it is not necessary for a closing mechanism of at least one door arrangement to be manually supplied with energy during the opening movement.

[0055] In a further embodiment, it can be provided that the at least one cable is arranged on at least one coupling gear of the at least one cable drive device, which coupling gear is spatially separate from the at least one drive device.

[0056] In the context of the present invention, the technical term "coupling gear" can be defined as a component connecting the at least one cable drive device to the at least one door assembly, which component converts a pulling movement of the at least one cable into a pivoting or rotational movement of the at least one door assembly. Gears and / or a transmission are generally not mandatory.

[0057] The at least one coupling gear can comprise a pivot arm for imparting the pivoting movement of the at least one coupling gear to the at least one door arrangement, which arm engages, for example, on a support hinge (for connecting a door leaf to the support) and / or, preferably directly, on the revolving door, folding door and / or folding sliding door.

[0058] The at least one coupling gear can be considered as part of the at least one cable drive device and / or as part of the at least one door arrangement.

[0059] However, the at least one cable drive device does not have to be connected to the coupling mechanism. For example, the coupling mechanism can have its own, preferably electric, drive unit.

[0060] The at least one coupling mechanism can function as a link between the at least one cable drive device and the at least one door assembly, wherein the at least one coupling mechanism can be driven alternatively or additionally via a rack in conjunction with a gearwheel. For example, the rack or the gearwheel can be provided for a bidirectional movement of the at least one door assembly within the receiving shaft, wherein the at least one cable drive device ensures a folding or folding process of the at least one door assembly.

[0061] According to an advantageous embodiment of the invention, it is provided that the at least one cable drive device is arranged by the at least one coupling gear, preferably via a profile rail arranged on the at least one door arrangement, on the at least one door arrangement and / or the support, preferably the hinge strip, and / or at least one support hinge.

[0062] Forces can be transmitted from the at least one coupling gear in a bidirectional direction via a profile rail, so that the at least one door arrangement can be moved both in the direction of the closed position and the open position via a pulling effect mediated by the at least one cable.

[0063] Particularly preferably, the at least one coupling gear is arranged on the carrier in a movement-coupled manner with the carrier.

[0064] The at least one coupling mechanism can generally also be arranged on the furniture body, preferably on the first guide rail. Preferably, the at least one coupling mechanism is arranged at least predominantly on the support.

[0065] It is preferably provided that the at least one cable drive device comprises at least one pulley for reducing a force acting from the at least one cable on the at least one door arrangement.

[0066] By means of the at least one pulley block, the force transmitted by the at least one cable drive device can be reduced by increasing the cable length used for force transmission for the movement of the at least one door arrangement. Particularly preferably, the force is at least halved and / or limited to a maximum of 50 N by the at least one pulley block.

[0067] It is preferably provided that the door arrangement is driven by the at least one cable drive device

[0068] - starting from the open position or a partially retracted position towards a retracted position, preferably up to the retracted position, and / or

[0069] - is moved from the retracted position or the partially retracted position towards the open position, preferably up to the open position.

[0070] It is particularly preferably provided that, starting from the door arrangement in the closed position, at least one pivot lever of at least one carriage is pivoted by the at least one cable and the at least one carriage remains stationary on a first guide rail, wherein the at least one pivot lever is then moved translationally along the first guide rail by the at least one cable in a movement-coupled manner with the at least one carriage.

[0071] By temporarily stopping the at least one carriage, the risk of jamming of the at least one door arrangement and the force required to move the at least one door arrangement is reduced.

[0072] Preferably, the at least one pivot lever transmits force from the at least one carriage to a hinge of the at least one door arrangement, preferably arranged in the edge region of a door leaf, preferably orthogonally to a door leaf plane in the closed position.

[0073] Particularly preferably, the at least one pivoting lever comprises a force accumulator for returning the pivoting lever to an initial position, wherein the force accumulator acts against the tensile force of the at least one cable.

[0074] According to a preferred embodiment, it is provided that the at least one cable engages at least one coupling gear, wherein a movement is imparted to the door arrangement by the at least one coupling gear via a force application by the at least one cable drive device.

[0087] Fig. 1a shows a piece of furniture 1, comprising a furniture body 2, a door arrangement 3 with a folding sliding door 11 for covering the furniture body 2 or other furniture located therein in a closed position 4 of the door arrangement 3 and a cable drive device 5, which in the illustration is concealed by a receiving shaft 17 arranged laterally next to the furniture body 2 and a cover of a first guide rail 14. Alternatively or in addition to the folding sliding door 11, a revolving door 10 or a folding door can be provided.

[0088] Fig. 1b differs from Fig. 1a only in that the door assembly 3 was moved from the closed position 4 into an open position 9 by a translational movement of a carriage 22 along the first guide rail 14. In the case of a folding door, coupling to a carriage 22 is generally not required.

[0089] Fig. 1c differs from Fig. 1b only in that the door assembly 3 was moved from the open position 9 into a retracted position 16 in the receiving shaft 17 by a translational movement. The door assembly 3 is movable between the open position 9 and a retracted position 16 within the receiving shaft 17 by the cable drive device 5.

[0090] The arrangement comprises a mechanical drive device in the form of an ejection device 18 for ejecting the door assembly 3 from the receiving shaft 17 and a hinge energy accumulator 30 for spreading the folding sliding door 11, wherein the door assembly 3 is movable by the mechanical drive device between the closed position 4 and the open position 9 and between the open position 9 and the retracted position 16. If a revolving door 10 is provided, a hinge energy accumulator 30 is generally not required.

[0091] The electrical drive device 6 and the mechanical drive device are arranged in the retracted position 16 between two planes spanned by the receiving shaft 17 and oriented parallel to a side wall of the furniture body 2. The ejection device 18 and electrical drive device 6 are arranged within the receiving shaft 17. The door arrangement 3 can be moved from the closed position 4 by the electrical drive device 6 between the closed position 4 and the retracted position 16. The door arrangement 3 can be moved from the retracted position 16 by the mechanical drive device between the retracted position 16 and the closed position 4.

[0092] The door assembly 3 is movable between the retracted position 16 and the open position 9 by the ejection device 18. Between the open position 9 and the closed position 4, the door assembly 3 is movable by the hinge force accumulator 30.

[0093] Fig. 2 shows components of the furniture 1 which, according to this embodiment, are used to move the door assembly 3. In this exemplary embodiment, the cable drive device 5 comprises an electric drive device 6 and a cable 7 which can be acted upon by the drive device 6, wherein the cable 7 is arranged on the carriage 22 of the door assembly 3 in such a way that the door assembly 3 can be moved via the cable drive device 5, starting from the closed position 4 or a partially open position 8 in the direction of the open position 9 up to the open position 9.

[0094] The drive device 6 is arranged in a stationary manner in a rear region of the receiving shaft 17 within the receiving shaft 17. The drive device 6 is arranged on a rear wall of the receiving shaft 17 and the longitudinal extent of the drive device 6 is oriented in the vertical direction. The cable extends from the drive device 6 to the carriage 22, which is arranged on the first guide rail 14 so that it can move between the open position 9 and the closed position 4. Alternatively or additionally, the drive device 6 - for example the cable drive device 5 or another movement mechanism - can be provided with a movement-coupled connection to a carrier 13 for mounting the door arrangement 3 on a guide device, as can be seen, for example, from the embodiments according to Fig. 10c and Fig. 10d.

[0095] A support 13 of the door arrangement 3, which is hidden in the illustration for reasons of clarity, is translationally movable along a second guide rail 15 arranged orthogonally to the first guide rail 14 between the open position 9 and the retracted position 16 laterally next to the furniture body 2.

[0096] The furniture 1 comprises the receiving shaft 17, which is defined laterally next to the furniture body 2 by two vertically aligned furniture panels, for receiving the at least one door arrangement 3 in a retracted position 16.

[0097] Within the receiving shaft 17, an ejection device 18 is provided for ejecting the door arrangement 3 in the direction of the open position 9, wherein an ejection force accumulator 19 of the ejection device 18 can be loaded by the movement of the door arrangement 3 in the direction of the retracted position 16 mediated by the cable drive device 5.

[0098] Fig. 3a shows the connection of the carriage 22 for the movement of the door arrangement 3 parallel to a front of the furniture 1 in an enlarged view, wherein it can be seen that the cable 7 is arranged on the carriage 22.

[0099] The carriage 22 comprises a pivot lever 23, wherein the pivot lever 23 is pivotally arranged on the carriage 22 and can be brought into contact with the door arrangement 3 in order to

[0100] To initiate or at least support the folding or spreading process of the door assembly 3. The pivot lever 23 is preferably provided, but is generally not absolutely necessary and can be replaced, for example, by an ejection device for bridging a dead center position of the door assembly 3 in the closed position, wherein the cable 7, for example, engages the base body of the carriage 22 and the ejection device is activated via a radio switch or by means of an overpressure movement.

[0101] The cable 7 is arranged on the pivot lever 23. A pivoting movement of the pivot lever 23 is limited by the carriage 22 by a stop 24 arranged on the carriage 22.

[0102] Fig. 3b shows a switch 26 for activating the cable drive device 5 to start the movement of the door assembly 3. The switch 26 can be connected to the drive device 6 by a cable or by transmitting a radio signal. The switch 26 is preferably arranged on a front of the furniture body 2 so as to be actuated via the door assembly 3, although manual actuation of the switch 26 at another position on the furniture 2 is also conceivable.

[0103] The switch 26 can generally be actuated in any way. For example, the switch 26 can be actuated by contact, by an overpressure movement of the door assembly 3, capacitively or inductively, etc. The switch 26 can be actuated, for example, by a hinge 27 which is actively or passively involved in transferring the door assembly 3 into the closed position 4, although this is not absolutely necessary. The switch 26 can, for example, be arranged on or in a horizontal furniture panel, such as a furniture top panel.

[0104] The hinge 27 - preferably made of metal and arranged on two door leaves - comprises the contacting means for the switch 26 shown in the illustration, wherein the contacting means is preferably made of plastic and is provided for securing the position of the door arrangement 3 in the closed position 4 with a coplanar alignment of the door leaves.

[0105] Fig. 3c shows the deflection of the cable 7 around a vertical edge of the furniture body 2, wherein a deflection device 21 for the cable 7 is arranged on the furniture body 2—connected to the first guide rail 14. The cable is deflected essentially by 90° via a deflection pulley.

[0106] Fig . 4a bis Fig .6b visualize a preferred movement of the door assembly 3 in the form of the folding sliding door 11 by the cable drive device 5, wherein an exemplary method for moving the door assembly 3 of the furniture 1 by the cable drive device 5 with the cable 7 coupled to the door assembly 3 can be exemplified as follows: The door assembly 3 is moved via the cable drive device 5 starting from the closed position 4 or the partially open position 8 in the direction of the open position 9 up to the open position 9 and starting from the open position 9 or the partially retracted position in the direction of the retracted position 16 up to the retracted position 16 or starting from the retracted position 16 or the partially retracted position in the direction of the open position 9 up to the open position 9 and starting from the open position 9 or the partially open position 8 in the direction of the closed position 4 moved to the closed position 4 .

[0107] The cable drive device 5 can cover the entire travel of the door assembly 3, although this is generally not necessary and, for example, only an opening process of the folding sliding door 11 or an opening process 10 of a revolving door can be provided. In Fig. 4a, the folding sliding door 11 is in the closed position 4 and can be fully unfolded and retracted into the receiving shaft 17 during the movement process by the cable drive device 5.

[0108] The folding sliding door 11 comprises, on the one hand, hinges 27 which connect the door leaves 28 of the folding sliding door 11 to one another in an articulated manner by a symmetrical arrangement on the door leaves 28 and which, in the closed position 4 or an overpressure position, are arranged on the cable 7 in such a way that a pretension can be imparted to the cable 7.

[0109] On the other hand, the folding sliding door 11 comprises a further hinge 27, which is also arranged on both door leaves 28 and can support or carry out the movement of the folding sliding door 11 into the closed position 4.

[0110] The further hinge 27 comprises a hinge force accumulator 30 for supporting the movement of the door arrangement 3 in the direction of the closed position 4, wherein the hinge force accumulator 30 can be loaded by the movement of the door arrangement 3 in the direction of the open position 9 mediated via the cable drive device 5.

[0111] The hinges 27 or the further hinge 27 can be used to actuate the switch 26 in the overpressure position.

[0112] Starting from the door arrangement 3 in the closed position 4 in Fig. 4a and Fig. 4b, in this embodiment the pivot lever 23 of the carriage 22 is pivoted by the cable 7 according to Fig. 5a and Fig. 5b and the carriage 22 initially remains stationary on the first guide rail 14, wherein the pivot lever 23 partially opens the folding sliding door 11 and then separates it from the folding sliding door 11 according to Fig. 6a and Fig. 6b, wherein the pivot lever 23 is moved translationally in the direction of the open position 9 by the cable 7 with the carriage 22 moving along the first guide rail 14.

[0113] In Fig . 6b the pivot lever 23 already rests against the stop 24 for limiting the pivoting movement and has been released from the door assembly 3 at a door assembly opening angle 25 of approximately 6 ° ( 15 ° is preferred ) .

[0114] Fig. 7a and Fig. 7b show a piece of furniture 1 in which a revolving door 10 is connected to the door assembly 3. The revolving door 10 is in the closed position 4.

[0115] The cable 7 of the cable drive device 5 engages a coupling gear 31, wherein the coupling gear 31 imparts a movement to the door arrangement 3 in the direction of the open position 9 or vice versa via a force application by the cable drive device 5.

[0116] In this embodiment, the cable drive device 5 can be in the rear region of the receiving shaft 17 or coupled in movement to the door arrangement 3, for example the support 13.

[0117] Preferably, the electric drive device 6 is mounted on the carrier 13.

[0118] By transmitting the force of the cable pull of the cable drive device 5 to the coupling gear 31, the door assembly can be moved—mediated by the coupling gear 31—starting from the open position 9 or the partially open position 8 in the direction of the closed position 4 up to the closed position 4. The number of cable drive devices 5 is generally arbitrary. For example, one cable drive device 5 can be provided for moving the door assembly 3 in the closing direction and another cable drive device 5 for moving the door assembly 3 in the opening direction, wherein one of the two directions of movement can be assumed alternatively or additionally, for example by an energy accumulator.

Generally, the coupling mechanism 31 can also impart rotation of the door assembly 3 to the hinge strip 12, which acts as a link between the support 13 and the door assembly 3. For example, the coupling mechanism 31 can transfer the force of the cable drive device 5 to the door assembly 3 by transmitting force to a support hinge 33.

[0122] The coupling mechanism 31 of this embodiment comprises a profile rail 32, via which the coupling mechanism 31 is arranged on the door assembly 3 for transmitting a tensile and / or compressive force to the door assembly 3. Generally, the coupling mechanism 31—acting as an intermediate link between the door assembly 3 and the cable drive device 5—can act directly on the support hinge 33.

[0123] The cable 7 is arranged on the coupling gear 31, which is spatially separated from the drive device 6.
