Description

State of the art

[0001] In the furniture and interior design industry, for example in kitchen applications, electronic or electric drive systems such as electromechanical pull-out systems are common. For instance, furniture components can be moved electrically, for example by an electric motor, relative to a stationary piece of furniture or interior design.

[0002] Such systems are comparatively complex in terms of function and structure, which does not always meet the requirements of practice from a technical or economic point of view.

[0003] The following are cited as state of the art: AT 526 678 B1, DE 11 2009 001 940 T5 and US 2022 / 0 265 046 A1. Purpose and advantages of the invention

[0004] The object of the present invention is to provide an alternative option for electric drive systems in the furniture and furnishings industry. In particular, an alternative drive system is to be provided, for example, for drawer systems. The drive system should be particularly easy to use and, for example, adaptable with minimal effort to existing guide systems for movable furniture and / or furnishing components.

[0005] This problem is solved by the subject matter of independent claim 1.

[0006] Further developments of the invention are shown in the additional claims.

[0007] The invention relates to a device for driving the movement of a furniture component in a furniture assembly, wherein the furniture component is mounted on a furniture carcass, the mounted state of the furniture component is configured via a guide arrangement so that the furniture component can be moved reversibly relative to the furniture carcass along a direction of movement of the furniture component by means of the guide arrangement, wherein the device is designed for an arrangement on the furniture and has a rotatable shaft with opposing end regions, wherein a contact element is provided at one end region of the shaft, so that when the shaft is rotated the contact element rotates together with the shaft, and wherein the device has a running section, wherein the contact element and the running section are in mutual contact, and wherein when the shaft is rotated the contact element performs a relative movement to the running section.wherein the device has an electric drive unit for driving the movement of the mounted furniture part in the direction of movement of the furniture part in the arranged state of the device on the furniture.

[0008] For example, the electric drive unit includes an electric motor. For example, the electric motor includes a linear actuator.

[0009] For example, there is exactly one contact element at exactly one end of the shaft. For example, there are exactly two contact elements. For example, there is exactly one contact element at each of the two end regions of the shaft.

[0010] For example, the relative motion includes a rotational motion of the contact element and superimposes a translational motion of the rotating contact element relative to the stationary running section.

[0011] The core of the invention lies in the fact that the drive unit has an output side which acts directly or indirectly on a point on the shaft, wherein this point on the shaft is spaced apart from the contact element, so that in a drive mode of the drive unit the shaft can be set into rotational motion, with the contact element rotating together with the shaft to move the furniture component. For example, existing guide arrangements of a furniture component, such as a guide unit for guiding the furniture component without a motor drive or with purely manual drive, can be equipped with an electric drive unit. For example, the furniture component is a drawer.

[0012] For example, the output side acts directly or indirectly on a point on the outside of the shaft. For example, this point on the outside of the shaft is spaced apart from the contact element. For example, the outside of the shaft can be understood as an outer surface of the shaft, or an outer surface such as an outer surface of the shaft. For example, the outside of the shaft is an outer surface of a profiled body of the shaft, such as a cylindrical profiled body of the shaft, e.g., the cylindrical outer surface of a cylindrical shaft. For example, the point on the outside of the shaft is an outer surface of a profiled body, such as the outer surface of a polygonal profiled body of the shaft.

[0013] For example, the driving contact of the output side occurs directly with the point on the outside of the shaft, such as the outer surface, for example through frictional contact of a friction wheel on the output side. Alternatively, the driving contact of the output side can occur indirectly with the point on the outside of the shaft, such as the outer surface, for example through meshing contact of a gear on the output side with a toothed ring mounted on the outside of the shaft at the relevant point.

[0014] The point on the shaft where the output side of the drive unit exerts its driving force is selectable. For example, the point on the shaft where the output side of the drive unit exerts its driving force is located in an end region of the shaft relative to the longitudinal axis, for example, in an outer third of the shaft's length. Alternatively, the point on the shaft where the output side of the drive unit exerts its driving force is located in a central region of the shaft relative to the longitudinal axis. Finally, the point on the shaft where the output side of the drive unit exerts its driving force is located in any region of the shaft relative to the longitudinal axis.

[0015] For example, the component forming the output side, e.g., comprising a motor drive shaft, with a transmission section on the drive shaft or as part of the drive shaft, acts directly on the outer surface of the shaft. This results in contact between the transmission section and the outer surface of the shaft. For example, the output side serves to transmit torque to the shaft.

[0016] For example, the output side includes a drive shaft such as a motor shaft, a motor shaft section, and / or a component coupled to a motor shaft of the drive unit. The term "output side" refers to a side of the drive unit that exerts a driving force on a subsequent side, originating from the drive unit.

[0017] Alternatively, an element, such as a gear element, can be interposed between the motor-shaft transmission section and the outer surface of the shaft, with the output side acting as an indirect driver. Instead of exactly one interposed element, exactly two or more than two interposed elements are also possible.

[0018] For example, the guide assembly of the furniture component includes a synchronization device with a synchronization shaft for synchronizing two identical units of the guide device present on the furniture component. For example, the shaft of the device and the synchronization shaft are one and the same component.

[0019] The shaft of the device is, for example, a single piece, such as a continuous round or cylindrical profile section, for instance an aluminum rod or tube, or another aluminum profile. Alternatively, the shaft is formed from several elements, each representing a portion of the shaft length, which are connected or assembled.

[0020] For example, the contact element is spaced away from the point on the outside of the shaft via which the transmission section is driven, e.g. longitudinally offset.

[0021] For example, the contact element is fixed to the shaft. For instance, the contact element is set into rotation by the driving force applied to the outer surface of the shaft, causing a relative movement of the movable furniture element to the furniture body. The contact element engages in the running section.

[0022] For example, the shaft is made of a metal material, such as a light-alloy material. For example, the shaft comprises an elongated base body, such as an elongated metal profile. For example, the shaft comprises an aluminum rod, such as an aluminum cylindrical profile.

[0023] For example, the device includes a control unit for operating the device. For example, the control unit includes software and a data storage device. For example, the control unit is designed to work together with a sensor device of the device. The sensor device serves, for example, to acquire sensor values ​​from the device. For example, the control unit controls the drive unit. For example, the control unit controls a parameter of the drive unit, such as the direction of rotation of the drive unit and thus of the output side, and thus the direction of rotation of the shaft and thus the direction of movement of the furniture component.

[0024] For example, the control unit monitors the rotational speed of the output side and thus the speed of the driven movement of the furniture component or the drive mechanism. For example, the control unit monitors the acceleration and / or deceleration values ​​of the output side. For example, a fully electronic device for driving the movement of the furniture component can be set up using the control unit and the sensor system. For example, the control unit can be used to implement a controllable movement sequence of the furniture component in an opening direction and / or a closing direction relative to the furniture body. For example, the control unit can be used to define additional functions of the device, such as collision protection for the furniture component and / or blockage detection.

[0025] For example, a first contact element is present at one end of the shaft, and a second contact element is present at another end of the shaft, such that when the shaft rotates, both contact elements rotate together with the shaft. The device has a first running section and a second running section, wherein the first contact element and the first running section are in contact with each other, and wherein the second contact element and the second running section are in contact with each other. When the shaft rotates, the first contact element moves relative to the first running section, and the second contact element moves relative to the second running section. For example, the two running sections are separate components. For example, the two running sections are spaced apart from each other by a clearance, e.g.,For example, the two running sections can be mounted to corresponding sections of the furniture carcass for use, such as on the inside of opposite side walls of the furniture carcass. The mounted furniture part is located between them. For example, the two running sections could be identical in design.

[0026] For example, a contact element may be integrally formed with the shaft or separately attachable to the shaft. For example, the first contact element and / or the second contact element may be rotationally fixed to the shaft. For example, there may be exactly one contact element at each of the two opposite ends of the shaft. For example, the two contact elements may be identical. For example, a contact element may be permanently or detachably attached to the shaft, e.g., to an elongated section of the shaft.

[0027] For example, a contact element is designed as an integral part of the shaft, e.g. formed in one piece with the shaft body of the shaft.

[0028] According to the invention, the output side of the drive unit comprises a transmission element which comes into contact with a contact section of the shaft, wherein the contact section on the shaft is formed in a longitudinal region of the shaft between the two opposing end regions. For example, the contact section on the shaft is present in a first third of the total length of the shaft.

[0029] For example, the transmission element is designed as a gear. For example, the transmission element is designed as a friction wheel.

[0030] According to the invention, the contact section on the shaft is formed in a longitudinal region of the shaft between the two opposing end-contact elements. For example, the contact section comprises an outer section of the shaft over a comparatively short axial extent. For example, the contact section is designed as an annular tooth profile that is fully enclosed around the shaft. If the transmission element is a pinion or gear, the tooth profile is matched to the gear profile of the gear for a suitable meshing of the shaft-side tooth profile and the gear profile. Then, in drive mode, i.e., with the drive unit electrically powered and switched on, the driven gear profile meshes with the tooth profile of the shaft, causing the shaft to rotate.

[0031] For example, the contact section is integrally formed on the shaft or attached to the shaft.

[0032] For example, a first axial segment of the shaft extends between the contact section and a first contact element. Similarly, a second axial segment of the shaft extends between the contact section and a first contact element. For example, the first segment is a multiple of the second axial segment. For example, the shorter axial segment is between 1 and 5 centimeters long. The shaft extends, for example, across the entire width of the furniture component, such as the entire width of a drawer. For example, the shaft is mounted to rotate slightly offset from the outer side of a drawer's back panel. The shaft's longitudinal axis, which is horizontally oriented in its operating state, runs parallel to a lateral direction of the furniture component, such as the longitudinal axis of a drawer's back panel.

[0033] For example, the axial length of the contact section on the shaft corresponds to a dimension of the transmission element in the direction of the axial length of the shaft. This ensures effective contact between the transmission element and the contact section. For example, the transmission element is the last gear pinion of a gear assembly between the drive unit and the shaft. The gear assembly is configured to control the rotational speed of the transmission element.

[0034] For example, exactly one transmission element or exactly one gear is provided, which meshes with a tooth or external tooth contour of the contact section of the shaft. Alternatively, it is conceivable that, for example, exactly two gears on the output side mesh with two spaced-apart contact sections of the shaft, like two tooth contours on the shaft.

[0035] For example, the transmission element is an additional element of the device that is part of a gear assembly. Alternatively, it is possible that the transmission element, or its function, is formed by a final gear element, e.g., a gear pinion, of the gear assembly.

[0036] For example, the contact section of the shaft is located in an end region of the shaft. For example, the end region of the shaft extends from a longitudinal end of the shaft to a point on the shaft that is a distance from the longitudinal end, where the distance of the point is between 5% and 20% of the total length of the shaft.

[0037] For example, the contact section includes a component section of the shaft itself located on the outside of the shaft. It is also possible that another element is permanently attached to the outside of the shaft, forming the contact section, for example, an annular pinion that is fitted onto the shaft and fixed to it.

[0038] In principle, the shaft can alternatively be designed over a significant portion or the entire length of the shaft, corresponding to the contact section. The torque transmission to the shaft can then be set up at any point freely selectable from several possible points along the shaft's length.

[0039] For example, a gear arrangement is provided for reducing and / or increasing the speed of a drive shaft of the electric drive unit. For instance, the gear arrangement provides a speed increase or decrease between the speed of the drive shaft and the transmission element. This allows the shaft speed, and therefore the speed of movement of the furniture component, to be preset.

[0040] For example, the transmission assembly is relatively small. For example, the transmission assembly is designed as a gear transmission. For example, the transmission assembly is designed as a compact transmission assembly.

[0041] For example, the gear assembly is a component of a drive assembly that includes the drive unit. Alternatively, the gear assembly is a separate unit downstream of the drive unit, e.g., between the drive unit and the contact section.

[0042] For example, mounting means are provided which are designed for attaching the shaft to a motion rail of the guide arrangement. According to the invention, mounting means are provided which are designed for attaching the electric drive unit to a motion rail of the guide arrangement. For example, the mounting means include screw, plug, and / or snap-fit ​​elements. This allows, for example, the drive unit and / or the shaft to be arranged on the motion rail and thus on the furniture component.

[0043] The device is attached, for example, exclusively to one drawer slide on opposite drawer guides of a drawer, if the furniture component is a drawer. Attachment to the furniture component itself is not possible. This allows the furniture component to be easily removed from the guide assembly, while the motion guidance device with shaft and drive unit remains attached to the guide assembly.

[0044] For example, an energy storage device such as a battery or accumulator is present on the furniture part to supply the electric drive unit.

[0045] For example, mounting devices are provided that are designed for attaching the shaft to an outer surface of the furniture component. This makes an alternative mounting option possible.

[0046] For example, the shaft and / or the electric drive unit is attached to the back wall of a drawer.

[0047] For example, the running section of the device is designed as a rack. For example, exactly two separate running sections are provided, e.g., exactly two separate racks.

[0048] For example, the running section of the device is designed as a separate component from the rest of the device. The running section can be attached to the furniture, for example, to a side panel of the furniture carcass. For example, a first running section and a second running section each comprise a toothed rack profile. For example, exactly two running sections, each with a rack, can be attached to opposite side panels of the furniture carcass. The running sections or racks of the device can be detachably attached, for example, with screws. For example, in the assembled operating state of the running sections, the toothed rack profile is horizontally oriented. A corresponding contact element on the shaft engages with the rack, rotating about a horizontal axis. The axis of rotation of the contact element corresponds, for example, to the central longitudinal axis of the shaft.For example, the longitudinal axis of the shaft is horizontally aligned and perpendicular to the longitudinal axis of the running section or perpendicular to the longitudinal axis of the rack. For example, the longitudinal axis of the rack is aligned parallel to the direction of movement of the furniture component as provided by the guide arrangement of the furniture component.

[0049] For example, the respective tooth profile of the running section or rack is vertically oriented downwards on the furniture. For example, the corresponding contact elements are located vertically below the tooth profile and mesh with it.

[0050] For example, the device is designed as a side stabilization arrangement for the furniture.

[0051] For example, a known side stabilization arrangement for furniture is designed such that, in the case of comparatively wide furniture parts or drawers, lateral tilting of the drawer is prevented. A tendency to tilt occurs, for example, when a pulling force is applied to the front, off-center or in lateral sections, to open the drawer, or a pushing force is applied to close the drawer. For example, gears or friction rollers are rotationally fixed to a torsion shaft and mesh with racks or run on a rolling surface. For example, the shaft of the device fulfills the function of the torsion shaft of the side stabilization arrangement. For example, a known side stabilization arrangement can be upgraded to the proposed device. For example, a known side stabilization arrangement can be retrofitted, e.g.,Additionally, a drive unit with a transmission element and a contact section on the shaft or torsion shaft are required. For example, all other components of the side stabilization assembly remain unchanged without modification.

[0052] The invention relates to a piece of furniture comprising a furniture body and a furniture component, wherein the furniture component is mounted to the furniture body via a guide arrangement, such that the furniture component can be moved reversibly relative to the furniture body along a direction of movement of the furniture component by means of the guide arrangement. A device according to one of the previously described embodiments is provided. For example, a side stabilization arrangement is provided on the furniture, with, for example, two gears that are rotationally fixed to the shaft or torsion shaft at their ends and that mesh with racks on opposite side walls of the furniture body. For example, in addition to the function of the side stabilization arrangement, a drive unit is provided to electrically drive the shaft, e.g., in both directions of rotation. The side stabilization also allows the furniture component to be electrically driven, like a drawer.This allows the drawer to be moved electrically in the opening and / or closing direction relative to the furniture body.

[0053] For example, the furniture could be kitchen furniture and / or kitchen fittings or kitchen appliances, e.g., with a drawer or the like. The guide assembly includes, for example, a rail guide designed as a full or partial extension, comprising a fixed rail and a moving rail in the case of a partial extension, and additionally a center rail in the case of a full extension.

[0054] This allows for a high level of user comfort without manually moving the drawer. Character description

[0055] Further features and advantages of the invention are explained with reference to schematically illustrated embodiments. Specifically, the following are shown: Fig. 1. A side view of a piece of furniture with a furniture part in a closed position and with a movement drive, omitting a first carcass side wall and with an associated guide arrangement. Fig. 2 the order according to Fig. 1 with the furniture part in an open position, Fig. 3 a perspective partial view of the furniture according to Fig. 2 without a first cabinet side panel, Fig. 4 den in Fig. 3. Area A is shown in an enlarged view. Fig. 5 the furniture part according to Fig. 1, Fig. 2 to Fig. 3 with guide arrangement present on both sides and pushed together, and a motion drive in a perspective rear view, Fig. 6 an enlarged section from Fig. 5 without the furniture part, wherein individual sections of the guide arrangement and the device for the movement drive are omitted and Fig. 7 a perspective front view of the section according to Fig. 6.

[0056] Fig. Figure 1 schematically shows a piece of furniture 1 with a cabinet 2 and a drawer section 3, for example, a drawer, where the drawer section 3 is mounted to the cabinet 2 via a guide assembly 4. The guide assembly 4 comprises two units with a first full extension 5 and a second full extension 6. The full extensions 5 and 6 are mounted on both sides of the drawer section 3 between the drawer section 3 and a respective side panel 7 of the cabinet 2. The guide assembly 4 serves to reversibly move the drawer section 3 along a first direction of movement S1, i.e., in an opening direction relative to the cabinet 2, and along a second direction of movement S2, i.e., in a closing direction. The cabinet 2, which is shown in the figures without a top panel but with upper strips 10 and 11, additionally has two opposing side panels 7, a back panel 8, and a bottom panel 9.

[0057] The furniture part 3 comprises a front 12, two side frames 13, 14 with railings 15, 16 arranged above them, a back panel 17 and a base 18.

[0058] The furniture 1 also includes a device 19 for driving the movement of the furniture part 3 in a mounted state of the furniture part 3 on the furniture body 2.

[0059] The device 19 for the movement drive of the furniture part 3 is designed for an arrangement on which the furniture 1 is mounted and has a rotatable shaft 20 with opposing end regions 20a, 20b.

[0060] A contact element 21 is present at the end region 20a of the shaft 20 and a contact element 22 is present at the end region 20b.

[0061] In the case of a rotation d1 or d2 (see below) Fig. 7) The contact elements 21, 22 rotate together with the shaft 20 about the longitudinal axis of the shaft 20, which defines a rotation axis D of the shaft 20.

[0062] The device 19 has a running section 23, wherein the contact element 21 and the running section 23 are in mutual contact. The device 19 has a running section 24, wherein the contact element 22 and the running section 24 are in mutual contact. The contact of the contact element 21 against the running section 23 and the contact element 22 against the running section 24 generates a drive torque for the linear movement of the furniture part 3 in direction S1 or S2, depending on the direction of rotation of the shaft 20. The running sections 23 and 24 are fixed in position to an inner side of an associated cabinet side panel 7.

[0063] When the furniture part 3 moves in the direction of S1 or S2, which is accompanied by a rotation of the shaft 20, the two contact elements 21 and 22 located at the ends of the shaft 20 rotate. The contact elements 21 and 22 are, for example, designed as gears with a circumferential tooth profile that is matched to a tooth profile 23a or 24a of the respective running section 23 or 24. For example, the running sections 23 and 24 are designed as a rack. When the furniture part 3 moves in the direction of S1 or S2 relative to the furniture body 2, the contact element 21 performs a relative movement to the running section 23 and meshes with its tooth profile 23a.

[0064] Accordingly, when the furniture part 3 moves in the direction of S1 or S2 relative to the furniture body 2, the contact element 22 performs a relative movement to the running section 24 and meshes with its tooth profile 24a.

[0065] The arrangement on the furniture 1 comprising the shaft 20 rotatably mounted on the furniture part 3 with the contact elements 21, 22 and with the two running sections 23 and 24, which are fixed in position inside the body side walls 7, form a side stabilization arrangement 25.

[0066] The device 19 is accordingly designed as a side stabilization arrangement 25.

[0067] The device 19 has an electric drive unit 26 for controlled, e.g., controlled, driven rotation of the shaft 20 in the directions of rotation d1 and / or d2, or in both possible directions of rotation d1, d2. The drive unit 26 has a drive shaft 26a, which is hidden in the figures and is shown in Fig. 6 is only indicated schematically or with dashed lines.

[0068] For example, the drive unit 26 is designed as an electromechanical drive unit 26. For example, the drive unit 26 includes an electric motor. For example, the drive unit 26 is designed as an electric motor. This enables a simple and retrofittable motion drive of the furniture part 3 mounted on the furniture body 2 in the direction of movement S1 and / or S2 of the furniture part 3 in the arranged state of the device 19 on the furniture 1.

[0069] The driven movement of the shaft 20 and the meshing action of the contact elements 21, 22 on the running sections 23 and 24 provide, in addition to synchronizing the operation and / or movement of the furniture part 3 relative to the furniture body 2, a drive for the furniture part 3 in the directions of movement S1 and / or S2. This enables automated driven movement of the furniture part 3, which translates into a high level of user comfort for the user of the furniture 1.

[0070] The drive unit 26 has an output side 27 with a transmission element 28. The transmission element 28, such as a pinion, is in Fig. 6 concealed by a gearbox housing part. A schematic outline of the transmission element 28 is shown in Fig. 6 is only indicated by dashed lines. For example, the output side 27 includes a drive shaft 26a that is only indicated, such as a motor shaft section of the drive unit 26 (see. Fig. 6) For example, the drive shaft 26a of the drive unit 26 is connected to the transmission element 28 via a gear arrangement 29, e.g., via a gear coupling. When the drive unit 26 is running, the transmission element 28 rotates, for example, controlled by a control unit 31 of the device 19. Alternatively, the transmission element 28 may be formed by a final gear element, e.g., a gear pinion, of the gear arrangement 29.

[0071] The driven rotating transmission element 28 acts in a driving manner on a contact section 30 on the shaft 20. The contact section 30 is located on the shaft 20 in a longitudinal region L (see figure). Fig. 5, Fig. 6) of the shaft 20 between the two opposing end regions 20a and 20b. For example, the contact section 30 is designed as a tooth profile section that is completely enclosed by the shaft 20. For example, when the drive unit 26 is running, the rotating transmission element 28 meshes with the contact section 30, which is designed, for example, as a tooth profile.

[0072] For example, mounting means 32 are provided which are designed for attaching the shaft 20 to a motion rail 33 of the guide arrangement 4. According to the invention, mounting means 32 are provided which are designed for attaching the electric drive unit 26 to a motion rail 33 of the guide arrangement 4. According to the invention, the mounting means 32 have a downwardly open cap 34 which encompasses a rear end region of the motion rail 33. The cap 34 is, for example, detachably or permanently connected to the motion rail 33.

[0073] In addition to or optionally with the mounting means 32, mounting means 35 are provided, which are designed for mounting the shaft 20 and / or the electric drive unit 26 on an outside of the furniture part 3. For example, a flange 36 with a through-bolt opening 37 is provided for mounting the device 19 on the rear wall 17 (see figure). Fig. 5).
