Description

[0001] Furniture with electrical and mechanical drive devices

[0002] The invention relates to a piece of furniture comprising

[0003] - a furniture body,

[0004] - 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,

[0005] - a receiving shaft arranged laterally of the furniture body, in which the at least one door arrangement can be moved at least partially into a retracted position,

[0006] - at least one electric drive device for applying force to the at least one door arrangement and

[0007] - at least one mechanical drive device, preferably an ejection device for ejecting the at least one door arrangement from the receiving shaft and / or hinge force accumulator for spreading open the folding door and / or folding sliding door.

[0008] Furthermore, the invention relates to a method for moving a door arrangement of such a piece of furniture.

[0009] A piece of furniture 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 is already known from the document DE 20 2020 107 104 Ul.

[0010] 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.

[0011] The objective technical object of the present invention is therefore to provide a piece of furniture which is improved over 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 a particularly comfortable movement tra ctory of the at least one door arrangement.

[0012] This problem is solved by the features of claim 1.

[0013] It is therefore provided according to the invention that the at least one door arrangement

[0014] - starting from a closed position by the at least one electric drive device at least partially between the closed position and the retracted position and

[0015] - starting from the retracted position, it is movable at least in regions between the retracted position and the closed position by the at least one mechanical drive device.

[0016] This makes it possible for the at least one door arrangement to be automatically movable, at least in some areas, bidirectionally between the closed position and the retracted position, without the operator having to apply manual force to the at least one door arrangement in order to move the at least one door arrangement.

[0017] Another positive feature is that the combination of electrical and mechanical drive devices allows for the advantageous use of an interaction between the two drive mechanisms. For example, the at least one electrical drive device can load the at least one mechanical drive device during a movement of the at least one door assembly (e.g., tension a power accumulator of the mechanical drive device), thus ensuring particularly user-friendly operation of the furniture.

[0018] As stated at the outset, protection is also sought for a method for moving a door arrangement of such a piece of furniture, wherein the at least one door arrangement

[0019] - by the at least one electric drive device, starting from the closed position, by the at least one electric drive device at least partially in the direction of the retracted position and

[0020] - by means of the at least one mechanical drive device, starting from the retracted position, the at least one mechanical drive device moves at least partially in the direction of the closed position.

[0021] The receiving shaft can, for example, be provided by an external space to the side of the furniture body or by an internal space within the furniture body.

[0022] Advantageous embodiments of the invention are defined in the dependent claims.

[0023] It is preferably provided that the piece of furniture has at least one cable drive device, wherein the at least one cable drive device comprises the at least one drive device and at least one cable which can be acted upon by force 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 via the at least one cable drive device.

[0024] This makes it possible for the at least one door arrangement to be movable in a user-friendly manner, after activation of the at least one cable drive device, fully automatically between the closed position and the open position and / or a retracted position next to or in the furniture body and the open position.

[0025] It is preferably 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.

[0026] 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 a parallel position to the receiving shaft does the force of the (electric) drive device overcome this pretensioning force to move it into the receiving shaft. The force-controlled locking is preferably achieved by a gear reduction.

[0027] 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 electric drive device.

[0028] The automatic loading process of the ejector eliminates the need to manually supply energy to an ejection mechanism.

[0029] It is preferably provided 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 movement-coupled to the at least one door arrangement, preferably to a support that may be present.

[0030] 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.

[0031] 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 a 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, wherein movements without a cable are also possible, for example by means of a coupling gear or a rack.

[0032] It is preferably provided that the at least one door arrangement via the at least one electric drive device

[0033] - starting from an open position or a partially retracted position towards a retracted position, preferably up to the retracted position, and / or

[0034] - is movable from the retracted position or the partially retracted position towards the open position, preferably up to the open position.

[0035] This makes it possible for the same 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.

[0036] It is preferably provided that at least one deflection device for the at least one cable is arranged on the furniture body, preferably on a guide rail which may be present, and / or in the

[0037] Receiving shaft is arranged. By means of the at least one deflection device - in particular at least one deflection roller - the at least one drive device can be stowed away concealed by a support at the rear in the receiving shaft and / or arranged at a suitable position on the furniture body and still generate a force transmission to a free end of the at least one door arrangement, in order in particular to cover an entire path of the at least one door arrangement with electrical or stored mechanical energy away from manual actuation or a jerky ejection movement.

[0038] 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.

[0039] It is preferably provided 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.

[0040] The at least one pivot lever can bridge a dead center position in the closed position. 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 pivot lever and the at least one door arrangement.

[0041] It is preferably 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.

[0042] 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.

[0043] It is preferably 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.

[0044] The at least one switch allows an opening or closing request from the furniture operator to 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 by an operator of the furniture. The switch can be arranged, for example, on a furniture side panel and / or a horizontally oriented furniture panel and / or on a remote control.

[0045] It is preferably provided that the at least one door arrangement can be folded and / or folded closed or opened and / or closed completely between the closed position and the open position by the at least one electrical drive device and / or the at least one door arrangement comprises a folding door and / or folding sliding door, wherein the folding door and / 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 which comprises a hinge energy accumulator for supporting a movement of the at least one door arrangement in the direction of the closed position, wherein the hinge energy 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 electrical drive device.

[0046] 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.

[0047] It is preferably provided that the at least one electric drive device is arranged on at least one coupling gear that is spatially separate from the at least one electric drive device.

[0048] In the context of the present invention, the technical term "coupling gear" can be defined as a component that connects the at least one electrical or mechanical drive device to the at least one door assembly, which component converts drive energy into a pivoting or rotational movement of the at least one door assembly. Gears and / or a transmission are generally not mandatory.

[0049] The at least one coupling mechanism can comprise a pivot arm for transmitting the pivoting movement of the at least one coupling mechanism to the at least one door assembly, which pivot arm engages, for example, a support hinge (for connecting a door leaf to the support) and / or, preferably directly, the revolving door, folding door, and / or folding sliding door. The at least one coupling mechanism can be considered part of the at least one drive device and / or part of the at least one door assembly.

[0050] However, the at least one 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.

[0051] The at least one coupling mechanism can function as a link between the at least one (preferably electric) 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 gearwheel can be provided for bidirectional movement of the at least one door assembly within the receiving shaft, wherein the at least one mechanical or electric drive device ensures a folding or folding process of the at least one door assembly.

[0052] It is preferably provided that the at least one electric 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.

[0053] Forces can be transmitted bidirectionally from the at least one coupling mechanism via a profile rail, so that the at least one door assembly can be moved both toward the closed position and toward the open position via a tensile force. Particularly preferably, the at least one coupling mechanism is arranged on the support in a movement-coupled manner with the support.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] In the retracted position 16, the electric drive device 6 and the mechanical drive device are arranged 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 the electric drive device 6 are arranged within the receiving shaft 17.

[0074] The door assembly 3 is movable from the closed position 4 by the electrical drive device 6 between the closed position 4 and the retracted position 16. The door assembly 3 is movable from the retracted position 16 by the mechanical drive device between the retracted position 16 and the closed position 4.

[0075] 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.

[0076] Fig. 2 shows components of the furniture 1 which, according to this embodiment, are used to move the door arrangement 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, the cable 7 being arranged on the carriage 22 of the door arrangement 3 in such a way that the door arrangement 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. The drive device 6 is arranged stationarily 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 as to be movable 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 support 13 for mounting the door assembly 3 on a guide device, as is evident, for example, from the embodiments according to Fig. 10c and Fig. 10d.

[0077] 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.

[0078] 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.

[0079] Within the receiving shaft 17, an ejection device 18 is provided for ejecting the door assembly 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 assembly 3 in the direction of the retracted position 16 mediated by the cable drive device 5. Fig. 3a shows the connection of the carriage 22 for the movement of the door assembly 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.

[0080] 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 initiate or at least assist an unfolding or spreading process of the door arrangement 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 arrangement 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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 .

[0087] The cable drive device 5 can cover the entire path of the door arrangement 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] The hinges 27 or the further hinge 27 can be used to actuate the switch 26 in the overpressure position. 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.

[0093] 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 ) .

[0094] 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.

[0095] 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.

[0096] 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.

[0097] Preferably, the electric drive device 6 is mounted on the support 13. 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—from the open position 9 or the partially open position 8 toward the closed position 4 up to the closed position 4.

[0098] 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.

[0099] Fig. 8a and Fig. 8b show an enlarged view of the coupling gear 31 connected to the cable 7 of the cable drive device 5.

[0100] The coupling mechanism 31 is arranged on the support 13 and is connected to the door assembly 3 (not shown in the illustrations). 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.

[0101] 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.

[0102] The cable 7 is arranged on the coupling gear 31, which is spatially separated from the drive device 6.

[0103] Fig. 10a to Fig. 10f show exemplary embodiments with a folding sliding door 11, wherein the folding sliding door 11 in the embodiments in Fig. 10b to Fig. 10f can be replaced by a revolving door 10 (without coupling to the carriage 22) or a folding door (without coupling to the carriage 22). The revolving door 10, the folding door or the folding sliding door 11 is connected to the support 13 via one end.

[0104] Fig. 10a shows parts of the furniture 1, wherein the drive device 6 of the cable drive device 5 is arranged at the rear in the receiving shaft 17 and the cable 7 is connected to the carriage 22 of the folding sliding door 11 of the door arrangement 3.

[0105] Starting from a closed position 4 or the partially open position 8 shown at the top left, the folding sliding door 11 is continuously unfolded by the cable drive device 5 toward the open position 9 shown at the bottom left (corresponding to the folding of the door leaves 18 of the door assembly 3).
