Description

[Technical field]

[0001] The present invention relates to a furniture drive for moving a furniture part supported movably relative to a furniture cabinet, in particular a furniture flap that can be pivoted relative to the furniture cabinet about a horizontal axis, the furniture drive having a casing that can be placed on a furniture plate of the furniture cabinet, at least one actuating arm supported movably relative to the casing, on which a movable furniture part can be attached, at least one force storage device capable of applying a force to the at least one actuating arm, at least one setting device for setting a force that can be applied from the at least one force storage device to the at least one actuating arm, and at least one display device capable of displaying force settings that can be implemented by the at least one setting device.The present invention further relates to a piece of furniture having a furniture cabinet and at least one furniture part supported movably relative to the furniture cabinet, in particular at least one furniture flap that can be pivoted relative to the furniture cabinet about a horizontal axis in a use position of the furniture.

[0002] Such a furniture drive is already known from German Utility Model No. 202010005934, in which the force setting of the actuating arm can be read off via an opening in another housing face of the housing, which is oriented parallel to the abutment face. The force setting can be manipulated via a setting device, the force setting being readable by the point of application of the force storage device at the intermediate lever, which is visible from the other housing face, via its relative position with respect to a scale located on the other housing face. Another furniture drive device is disclosed in U.S. Patent Application Publication No. 2019 / 178. 0 16, Chinese Utility Model No. 210768305, German Utility Model No. 212017000269, as well as WO 2016 / 077851.

[0003] A disadvantage of the prior art is that contaminants can get into the furniture drive through the openings in the other housing surface, which creates the risk of impairing the function and / or reducing the service life of the furniture drive. Furthermore, the aesthetic image of the furniture drive is impaired, and if the other housing surface is completely closed, the force setting can only be read by laboriously dismantling and then reassembling the other housing surface, in which case there is no reference point for the scale. Furthermore, reading the force setting is difficult in the case of tall furniture and / or furniture in which the furniture drive is located very far back or in a place where access is difficult, in particular in this case the deviation of the user's gaze direction of different sizes leads to significant parallax effects when reading the force setting - due to different eye heights - so that a sufficiently accurate reading of the force setting is not possible.

[0004] The technical problem addressed by the present invention is therefore to provide an improved furniture drive device with respect to the prior art, which at least partially overcomes the disadvantages of the prior art and which is distinguished in particular by a display device which is easier to read by the user, in order to enable the furniture drive device to be attached to furniture more flexibly, for example with an improved appearance and the possibility of more accurate reading of the force settings compared to the prior art.

[0005] This problem is solved by the features of claim 1.

[0006] Thus, according to the invention, the casing has an abutment surface, by means of which the furniture drive can be abutted against a furniture board, and the casing further has at least one casing surface oriented transversely to the abutment surface, in which case the at least one display device is arranged relative to the at least one casing surface such that the at least one display device is readable in a line of sight towards the at least one casing surface. At least one of the casing surfaces is arranged on the underside of the casing of the furniture drive in a use position where the furniture drive is arranged on a furniture board. It is expected that this will happen.

[0007] This allows firstly for at least one further housing surface, which is oriented, for example, parallel to the abutment surface, to be formed completely closed and prevents the ingress of contaminants into the furniture drive. If the at least one housing surface is located on the underside of the furniture drive in the use position in which the furniture drive is arranged on a furniture board, then it is possible to particularly effectively prevent dust and contaminants from reducing the functionality and / or the service life of the furniture drive.

[0008] Furthermore, there is the advantageous property that the reading of the force setting is independent of the explicit configuration of the at least one further housing surface, in which case reading of the force setting is easily possible by looking at the at least one housing surface, even if the at least one further housing surface is completely closed. Furthermore, parallax effects can be reduced in a particularly favorable manner.

[0009] As mentioned at the beginning, the patent also claims a piece of furniture having a furniture cabinet and at least one furniture part supported so as to be movable relative to the furniture cabinet, in particular at least one furniture flap which, in the use position of the furniture, can be pivoted relative to the furniture cabinet about a horizontal axis, the furniture having at least one such furniture drive device, the furniture cabinet having at least one furniture board, in particular arranged vertically, a casing of the at least one furniture drive device being arranged on the furniture board, the at least one furniture part being attached or attachable to at least one actuating arm of the at least one furniture drive device, and the at least one furniture part being movable relative to the furniture cabinet by means of the at least one furniture drive device.

[0010] To identify the current force setting of the at least one furniture drive, it is only necessary that at least one casing face is accessible, in which case the user can obtain information about the current setting of the force that can be applied from the at least one force storage device to the at least one actuating arm by looking at the at least one display device. It is also conceivable that the at least one furniture drive is veneered in certain areas in order to improve the aesthetic image, in which case the at least one display device is readable from the at least one casing face and / or the force setting can be adjusted, for example, via an end face.

[0011] Advantageous embodiments of the invention are defined in the dependent claims.

[0012] It is particularly preferred that the at least one setting device is operable from an end face, preferably through an end face opening of the casing - preferably in the use position of the furniture drive device, in which the casing is arranged on a furniture board of the furniture cabinet - and the end face is preferably arranged transversely to the abutment face and the casing face.

[0013] The adjustment of the force setting can be performed particularly conveniently if the actuation of the force setting is performed by means of at least one setting device via the end face, for example the at least one setting device can be actuated by means of a screw driver from an end face opening, in which case the at least one display device displays the changed force setting on at least one housing face which is inclined, particularly preferably by substantially 90°, to the end face.

[0014] Furthermore, it is particularly preferred that the casing has at least one further casing surface which is arranged parallel to the at least one abutment surface, and by means of the at least one further casing surface a surface of the furniture drive can be shielded at least in a certain area.

[0015] This at least one further casing surface is not required for setting the force by means of the at least one setting device or for reading the force setting by means of the at least one display device, removal of the at least one further casing surface is only required for maintenance purposes and / or the at least one further casing surface can be configured opaque and / or closed.

[0016] The at least one further casing surface may generally have, for example, a chamfer and / or a web which shields the further surface of the furniture drive in addition to the surface of the furniture drive and / or may be formed separately from or by the casing.

[0017] Advantageously, according to one embodiment of the invention, it may be provided that the at least one display device is formed, preferably spatially, separate from the at least one setting device.

[0018] This allows the at least one display device to be made from a different material, for example in order to reduce the weight of the furniture drive, and / or to be particularly well maintained when changing the at least one force storage device.

[0019] Particularly preferably, the at least one display device is formed separately from the at least one force storage device, the at least one actuating arm and / or any transmission means, such as an intermediate lever, but generally the at least one display device can be materially connected to the at least one setting device, the at least one force storage device, the at least one actuating arm and / or any transmission means.

[0020] According to an advantageous configuration of the invention, it is provided that the at least one actuating arm has at least one gear for moving the at least one actuating arm from a first relative position to a second relative position distinct from the first relative position, and preferably it is provided that the at least one gear is in indirect or direct contact with the at least one setting device.

[0021] The at least one gear can generally have a gear ratio that allows a particularly good force transmission from the at least one force storage device to the at least one actuating arm in order to move the movable furniture part while reducing the effort.

[0022] By means of the at least one gear wheel, a linear and / or pivoting movement - exerted by the at least one force storage device - can be converted into a rotational movement of the at least one actuating arm. In general, however, the at least one actuating arm may also have a linear movement course.

[0023] Advantageously, it is envisaged that the at least one setting device has at least one transmission means, and that the at least one force storage device is arrangeable on the at least one transmission means and / or that the at least one transmission means is arrangeable on at least one actuating arm, preferably via a control cam of the at least one transmission means.

[0024] By means of the at least one transmission means, the point of application of the at least one force storage device on the at least one actuation arm can be shifted, so that the changed force arm of the at least one force storage device acts on the at least one actuation arm and generates a higher or lower force for moving the movable furniture part. Furthermore, the at least one force storage device can already be partially unloaded or have a higher preload due to the change in the point of application, so that the transmission of the force to the at least one actuation arm can be adapted to the requirements for the movable furniture part.

[0025] Via the control cam, the force transmission to the at least one actuating arm can be particularly preferably influenced during the movement of the at least one actuating arm, the control cam particularly preferably having at least two regions of different geometry, such as curves or inclined surfaces, so that the force application course can be particularly advantageously influenced. In general, however, the control cam can also be in the form of a recess, by means of which the at least one actuating arm is moved in a defined manner by the at least one setting device and / or is positioned relative to the at least one setting device in a defined manner during the movement of the at least one actuating arm.

[0026] It is indicated that it is advantageous that the at least one force storage device is movable along a line of action of the at least one setting device, preferably of at least one transmission means optionally present, preferably by means of an adjustment device, for changing the force transmission moment for the at least one actuating arm, and that the at least one adjustment device is preferably movable translationally via the at least one setting device.

[0027] The adjustment device particularly preferably serves as a connecting element between the at least one setting device and the at least one force storage device, in which case the relative position between the at least one force storage device and the at least one setting device can be adjusted via the at least one setting device, for example in order to shift the point of application of the at least one force storage device relative to the at least one actuating arm.

[0028] According to an advantageous embodiment of the invention, it is envisaged that at least one damping device is arranged in the casing, which can be or is arranged on the at least one setting device, on the at least one force storage device and / or on the at least one actuating arm.

[0029] The at least one damping device allows for a coordinated movement of the at least one actuating arm and prevents sudden movements which may damage components of the furniture drive.

[0030] It is indicated that it is advantageous for the at least one display device to be arranged, at least in a predefined area, on the at least one energy storage device and / or on the at least one setting device, in which case it is preferably provided that the at least one display device is formed, particularly preferably completely, from metal.

[0031] The at least one display device can be in contact with the at least one force storage device, for example indirectly via an adjustment device. In general, it is also conceivable that the at least one display device is arranged, preferably indirectly, on the at least one force storage device or on the at least one setting device, so that changes in the force settings are transmitted to the at least one display device.

[0032] An advantageous embodiment consists in that the at least one display device is rotatably supported on the casing and / or on the at least one setting device.

[0033] Thereby, a change in the force setting can be converted into a rotational movement of the at least one display device. For example, the at least one display device can have a preferably curved scale on its periphery that can be rotated or pivoted relative to a component of the furniture drive, so that the force setting can be read off via the relative position of the scale with respect to the component.

[0034] Particularly preferably, the at least one display device is arranged inside the casing, at least in a certain area, preferably completely, and in this case it is preferably provided that the at least one display device is readable through at least one opening in the casing.

[0035] This allows the kinematic mechanism of the display device to remain hidden within the casing, and only the information necessary for the force setting is accessible to the user of the furniture drive.

[0036] In one embodiment of the invention, it is provided for the at least one display device to have at least one plate-like extension, preferably in the form of a sheet metal part, particularly preferably curved, for converting and showing the force setting of the at least one setting device on the at least one display device.

[0037] Through the curvature of the at least one plate-shaped extension, the conversion of the force setting into the scale to be read can be achieved particularly well due to the interaction of the at least one force storage device and / or the at least one setting device with the at least one plate-shaped extension upon contact during a movement - issued by the at least one setting device.

[0038] According to a preferred embodiment of the invention, it is provided that the at least one plate-like extension is movable relative to the at least one setting device by movement of the at least one force storage device, preferably via at least one adjustment device, which may be present, and / or by rotation.

[0039] It is shown to be advantageous that the at least one display device has at least one scale, which is movable relative to the casing when the force that can be applied from the at least one force storage device to the at least one actuating arm is set by the at least one setting device, and in this case it is preferably provided that the at least one scale is formed curvedly, particularly preferably convexly.

[0040] In the prior art, the scale is arranged on the casing, and in order to be able to indicate a wide range of force settings, the scale must be very long. In this case, a solution with a scale arranged on the at least one display device reduces the visible portion for determining the force settings, preferably making visible only the area of ​​the at least one scale required for determining the force that can be applied from the at least one force storage device to the at least one actuating arm. This can be ensured, for example, by at least one opening in the casing surface, which makes it possible to read only the relevant partial area of ​​the at least one scale.

[0041] It is furthermore preferably provided that the at least one scale and the at least one plate-like extension are formed spatially distinct from one another.

[0042] According to an advantageous configuration of the invention, it is provided that the casing has at least one marking by means of which the force setting which can be carried out by the at least one setting device can be read off by the relative position of the at least one display device, preferably of at least one scale which may be present, in relation to the at least one marking.

[0043] The at least one marking and / or the at least one graduation may be formed, for example, by embossing, punching, perforating, gluing, painting, engraving, or the like.

[0044] In another embodiment, it may be envisaged that the at least one setting device has an adjustment mechanism, preferably in the form of a tool receptacle, which is operable, particularly preferably on the end side, via which the setting of the force that can be applied from the at least one force storage device to the at least one actuating arm can be adjusted.

[0045] The adjustment mechanism allows the force setting to be adapted to a desired force setting in a manner that is simple for the user - for example via manipulating the tool receptacle by means of a screw driver.

[0046] Further details and advantages of the invention are explained in more detail below with reference to the description of the drawings and with reference to the exemplary embodiment shown in the drawings. [Brief description of the drawings]

FIG. [Figure 8] FIG. 1b is a perspective view of a piece of furniture according to a preferred embodiment, which is provided with a furniture drive device according to the embodiment of FIG. 1a; [Figure 9] FIG. 9 is another perspective view of the furniture according to the embodiment of FIG. 8.

[0048] FIG. 1a shows a furniture drive device 1 for moving a furniture part 3 supported so as to be movable relative to a furniture cabinet 2, the furniture drive device having a casing 4 which can be placed on a furniture plate 5 of the furniture cabinet 2, an actuating arm 6 supported so as to be movable relative to the casing 4, and a force storage device 7 capable of applying a force to the actuating arm 6.

[0049] The furniture drive device 1 has a setting device 8 for setting the force that can be applied to the operating arm 6 from the force storage device 7, in which case a display device 9 is provided that can display the force settings that can be implemented by the setting device 8.

[0050] The casing 4 of the furniture drive 1 has an abutment surface 31, with which the furniture drive 1 can abut against a furniture board 5. The casing 4 has a casing surface 32 oriented transversely to the abutment surface 31, with the display device 9 being arranged relative to the at least one casing surface 32 such that the display device 9 is readable in a line of sight towards the at least one casing surface 32.

[0051] Figure 1b shows an enlarged view of a partial region of the furniture drive from Figure 1a, from which it becomes clear that the display device 9 is formed separately from the setting device 8, the force storage device 7 and the actuation arm 6. The display device 9 is pivotally supported on the setting device 8 and is in contact with the force storage device 7 via an adjustment device 17.

[0052] The actuating arm 6 has two gears 12 for moving it from a first relative position to a second relative position different from the first relative position, allowing a movement of the actuating arm 6 from an open position to a closed position of the movable furniture part 3 and vice versa. The gears 12 are in direct contact with the setting device 8 via a control cam 16 in the form of a recess in a transmission means 15 of the setting device 8. The transmission means 15 may also have a control cam 16 allowing a force transmission to the movable furniture part 3 which generally varies with a change in the relative position.

[0053] The transmission means 15 of the setting device 8 is in contact with the force storage device 7, which can be translated via the adjustment device 17 along a line of action 18 of the transmission means 15 of the setting device 8. The translational movement can generally be superimposed with a pivoting movement. Due to the movement of the adjustment device 17 along the line of action 18, the point of action of the force storage device 7 is shifted relative to the actuation arm 6, so that the force transmission moment to the actuation arm 6 is changed.

[0054] The adjustment device 17 can be translated via the setting device 8, in which case the furniture drive 1 is in a first force setting and the force storage device 7 acts on the transmission means 15 above in the figure. This corresponds to a low force setting.

[0055] Figure 2a shows the furniture drive 1 in a changed force setting with a relatively higher force transmission of the force storage device 7 to the actuating arm 6 compared to Figure 1a, where the force storage device 7 acts on the transmission means 15 below in the drawing and transmits force to the actuating arm 6 via the force setting device 8.

[0056] A damping device 19 is arranged in the casing 4, which is arranged during the damping movement on the actuating arm 6 and indirectly on the setting device 8. Generally, however, the damping device 19 can also be arranged on the force storage device 7.

[0057] The display device 9 is supported on the casing 4 via a further casing surface 27 (not shown for reasons of clarity) and is pivotally supported on the setting device 8. Generally, the display device 9 may also be arranged on the force accumulation device 7.

[0058] The display device 9 is made entirely of metal.

[0059] The setting device 8 is arranged on the force storage device 7 via an adjustment device 17 and on the actuating arm 6 via a transmission means 15 .

[0060] FIG. 2b differs from FIG. 2a only in that a part of the furniture drive 1 is shown in an enlarged view.

[0061] If the display device 9 moves during a movement of the actuating arm 6 - for example during a change in the opening angle of the movable furniture part 3 - it is moved relative to the casing 4, so that the force setting effected via the setting device 8 can be shown differently on the display device 9. However, this is not a problem, since a user of the furniture drive can deduce the force setting simply by reading the force setting of the furniture drive 1 in one particular position of the actuating arm 6. The display on the display device 9 can therefore not at all only depend on the force setting of the setting device 8, but gives information about the current force setting.

[0062] In practice, it is particularly important how the force settings of two corresponding furniture drives 1 were made relative to one another. It is therefore sufficient to compare the force settings with one another via the display devices 9 of both furniture drives 1 in any position of the working arm 6, in which case, if the information on the display devices 9 differs, the force setting via the setting device 8 of one of the two furniture drives 1 can be adapted by adjusting the point of application of the force storage device 7 on the associated working arm 6, so that the same force settings can be read off by the display devices 9 in the same position of the working arm 6.

[0063] 3 shows the furniture drive 1 in a viewing direction towards the casing face 32, with the display device 9 arranged inside the casing 4 and readable through an opening 29 in the casing 4. The shape of the opening 29 is generally arbitrary. In general, the display device 9 may protrude from the opening 29 or may be located inside the casing 4 and visible through the opening 29; particularly preferably, the display device 9 is arranged in the opening 29.

[0064] The display device 9, which is separate from the casing 4, has a scale 21, which is moved relative to the casing 4 when the force that can be applied from the force storage device 7 to the actuating arm 6 is set by the setting device 8. The scale 21 is formed convexly curved. The scale 21 is independent of the casing 4; however, a scale 21 arranged on a casing surface 32 is also conceivable, in which case the force setting can be read off from the underside of the casing 4 via the relative position of the display device 9 relative to this scale 21 - for example by means of a marking on the display device 9.

[0065] The casing 4 has two markings 22 arranged on the casing face 32, by means of which the force settings which can be carried out by the setting device 8 can be read off depending on the relative position of the display device 9 via the scale 21 in relation to the markings 22.

[0066] Figure 4 shows the furniture drive 1, in which the scale 21 has been moved relative to the position of Figure 3 with respect to the marking 22. With respect to Figure 3, the force setting, which is effected via the setting device 8, has been changed, as a result of the force storage device 7 being slid along the line of action 18 of the transmission means 15 via the adjustment device 17. Due to the change in the point of action of the force storage device 7 on the actuation arm 6, the force transmission moment changes, so that the force setting becomes higher (despite the increased preload of the force storage device 7).

[0067] By moving the adjustment device 17, the display device 9 rotates and the scale 21 is moved relative to the markings 22. The change in the point of application of the force storage device 7 is kinematically linked to the movement of the display device 9.

[0068] The scale 21 has intervals, inside which a number is respectively arranged, which represents the current interval on the scale 21. However, in general, other indications of the current force setting are also conceivable, in which case the scale 21 is not limited to the illustrated indication of the force setting.

[0069] The marking 22 is provided in the form of an engraved line; however, generally, other markings are also possible, such as, for example, glued-on arrows or pointers, from which the force setting can be read off by means of the display device 9 .

[0070] FIG. 5a shows the structural arrangement of some components used for modifying and displaying force settings according to a preferred embodiment of the furniture drive 1.

[0071] The setting device 8 has a rolling body that comes into contact with the operating arm 6 when the movable furniture piece is moved, and this rolling body is rotatably supported by the setting device 8 .

[0072] FIG. 5b shows an enlarged view of the display device 9, which has a curved plate-like extension 20 in the form of a sheet metal part for converting and showing the force setting by the setting device 8 on the display device 9.

[0073] The plate-like extension 20 is brought into a rotational movement relative to the setting device 8 by movement of the force storage device 7, preferably by means of the adjustment device 17, whereby the scale 21 is moved relative to the opening 29.

[0074] A reset element 30 with a free end is materially connected to the display device 9, which reset element 30 biases the display device 9 in the direction of the starting position, unless the display device 9 is biased in the opposite direction by the setting device 8. For example, the display device 9 is moved from the starting position to a force setting position, in which case the reset element 30 returns the display device 9 to the starting position again as soon as the force setting position is released.

[0075] The reset element 30 is spring-elastic and is arranged on the opposite side of the plate-like extension 20. On the side of the reset element 30, the scale 21 is arranged parallel to the web-like extension, and the scale 21 and the reset element 30 are connected to the joint area of ​​the display device 9 via connecting elements that are arranged between the reset element 30 and the scale 21 and the plate-like extension 20.

[0076] FIG. 6a shows the components shown in FIG. 5a in an assembled state.

[0077] Figure 6b shows the assembled components of the furniture drive 1 according to figure 6a in a viewing direction towards the casing surface 32. The scale 21 arranged on the display device 9 is readable through the opening 29, by means of which the force setting can be deduced.

[0078] FIG. 7 a shows the component of the furniture drive 1 with a changed position of the display device 9 relative to the marking 22 on the casing 4 .

[0079] The scale 21 and the plate-like extension 20 are formed spatially separate from one another.

[0080] In Fig. 7b it is clear that due to the change of the force setting via the setting device 8 there is a changed relative position of the display device 9. When the adjustment device 17 is slid anew to the force setting position marked "3", the plate-like extension 20 (see Fig. 7a) is likewise moved by the reset element 30 to this relative position of the display device 9, due to the reset element 30 being supported on the setting device 8. Generally, however, the reset element 30 may also be supported on a separate component.

[0081] Figure 8 shows a piece of furniture 25 which comprises a furniture cabinet 2 and a furniture part 3 supported for movement relative to the furniture cabinet 2 in the form of a furniture flap which, in the use position of the furniture 25, is pivotable relative to the furniture cabinet 2 about a horizontal axis.

[0082] The furniture 25 comprises a furniture drive 1, in which a furniture cabinet 2 has a vertically arranged furniture board 5, a casing 4 of the furniture drive 1 being arranged on the furniture board 5. A furniture part 3 is attached to a movably supported actuating arm 6 of the furniture drive 1, which furniture part 3 is movable relative to the furniture cabinet 2 by means of the furniture drive 1.

[0083] The casing 4 has a further casing surface 27 which is arranged parallel to the abutment surface 31. A side surface 28 of the furniture drive 1 can be completely shielded by the further casing surface 27. A casing surface 32 is arranged between the further casing surface 27 and the abutment surface 31.
