Description

[0001] The invention relates to a furniture drive for moving a furniture part that is mounted so as to be movable relative to a furniture body, in particular a furniture flap that can be pivoted about a horizontal axis relative to the furniture body, comprising a housing that can be arranged on a furniture panel of the furniture body, at least one actuating arm that is mounted so as to be movable relative to the housing and to which the movable furniture part can be fastened, at least one force storage device with which a force can be exerted on the at least one actuating arm, at least one adjusting device for adjusting the force that can be exerted by the at least one force storage device on the at least one actuating arm, and at least one display device with which a force setting that can be made by means of the at least one adjusting device can be displayed.Furthermore, the invention relates to a piece of furniture comprising a furniture body and at least one furniture part mounted so as to be movable relative to the furniture body, in particular at least one furniture flap which can be pivoted about a horizontal axis relative to the furniture body in the position of use of the furniture.

[0002] Such a furniture drive is already known from DE 20 2010 005 934 U1, in which a force setting of an actuating arm can be read via an opening in a further housing side oriented parallel to a contact surface. The force setting can be manipulated via an adjustment device, whereby the force setting can be read via a point of application of a force storage device on an intermediate lever, visible through the further housing side, via a relative position to a scale located on the further housing side.

[0003] A disadvantage of the current technology is that contaminants can enter the furniture drive through the opening in the additional housing side, which poses the risk of impaired functionality and / or a reduced service life of the furniture drive. Furthermore, the aesthetic appearance of the furniture drive is diminished. With a completely closed additional housing side, reading the force setting is only possible through the complex disassembly and subsequent reassembly of the additional housing side, which, however, does not provide a reference to the scale.Furthermore, reading the force setting is difficult in the case of tall furniture and / or furniture on which furniture drives are arranged very low or are difficult to access, whereby significant parallax effects are generated when reading the force setting, particularly due to different viewing directions of users of different sizes - caused by varying eye heights - which means that a sufficiently precise reading of the force setting cannot be achieved.

[0004] The objective technical problem of the present invention is therefore to provide a furniture drive which is improved compared to the prior art, in which the disadvantages of the prior art are at least partially eliminated, and which is characterized in particular by a user-friendly display device in order to be able to use the furniture drive more flexibly on furniture, for example, with an improved appearance compared to the prior art and the possibility of a more precise reading of the force setting.

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

[0006] It is therefore provided according to the invention that the housing has a contact surface with which the furniture drive can be brought into contact with the furniture panel and the housing has at least one housing side oriented transversely to the contact surface, wherein the at least one display device is arranged relative to this at least one housing side in such a way that the at least one display device can be read when looking towards this at least one housing side.

[0007] This makes it possible for at least one additional housing side, which is oriented parallel to the contact surface, for example, to be completely closed, thus preventing the ingress of dirt into the furniture drive. If the at least one housing side is located on an underside of the furniture drive in a use position in which the furniture drive is arranged on the furniture panel, this can be particularly effectively prevented from reducing the functionality and / or service life of the furniture drive by dust and dirt.

[0008] Another positive feature is that the force setting can be read independently of the explicit design of the at least one other housing side. Even when at least one other housing side is fully closed, the force setting can be conveniently read by looking at the at least one housing side. Parallax effects can also be reduced to a particularly advantageous extent.

[0009] As stated at the outset, protection is also sought for a piece of furniture having a furniture body and at least one furniture part mounted so as to be movable relative to the furniture body, in particular at least one furniture flap which, in the position of use of the furniture, can be pivoted about a horizontal axis relative to the furniture body, wherein the piece of furniture has at least one such furniture drive, wherein the furniture body has at least one, in particular vertically arranged, furniture panel and the housing of the at least one furniture drive is arranged on the furniture panel, and wherein the at least one furniture part is fastened or can be fastened to the at least one actuating arm of the at least one furniture drive, wherein the at least one furniture part can be moved relative to the furniture body by the at least one furniture drive.

[0010] To identify the current force setting of the at least one furniture drive, it is only necessary that at least one housing side is accessible, whereby a user can generate information on the current setting of the force exerted by the at least one force storage device on 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 partially covered to enhance its aesthetic appearance, whereby the at least one display device can be read through the at least one housing side and / or the force setting can be adjusted, for example, via a front side.

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

[0012] It is particularly preferably provided that the at least one adjusting device - preferably in a position of use of the furniture drive in which the housing is arranged on the furniture panel of the furniture body - can be actuated from an end face, preferably via an end face opening of the housing, wherein the end face is preferably arranged transversely to the contact surface and the housing side.

[0013] If the force setting is manipulated via the front side using the at least one adjustment device, the force setting can be generated particularly conveniently. For example, the at least one adjustment device can be actuated with a screwdriver through the front side opening, with the at least one display device displaying the changed force setting on the at least one housing side, which is particularly preferably inclined at substantially 90 degrees to the front side.

[0014] Furthermore, it is particularly preferably provided that the housing comprises at least one further housing side, wherein the at least one further housing side is arranged parallel to the at least one contact surface and one side of the furniture drive can be covered at least in part by the at least one further housing side.

[0015] The at least one further housing side is required neither for the force adjustment via the at least one adjustment device nor for reading the force adjustment via the at least one display device, wherein disassembly of the at least one further housing side may only be required for maintenance purposes and / or the at least one further housing side may be opaque and / or closed.

[0016] The at least one further housing side can generally comprise, for example, folds and / or webs with which, in addition to the side of the furniture drive, further sides of the furniture drive are concealed, and / or can be formed separately from the housing or by the housing.

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

[0018] As a result, the at least one display device can be made of a different material, for example to reduce the weight of the furniture drive, and / or can be maintained in a particularly advantageous manner when the at least one force storage device is changed.

[0019] Particularly preferably, the at least one display device is configured 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. In general, however, the at least one display device can also be integrally connected to the at least one adjustment device, the at least one force storage device, the at least one actuating arm, and / or any transmission means.

[0020] According to an advantageous embodiment of the invention, it is provided that the at least one actuating arm comprises at least one gear for moving the at least one actuating arm from a first relative position into a second relative position separate from the first relative position, wherein it is preferably provided that the at least one gear contacts the at least one adjusting device directly or indirectly.

[0021] The at least one gearwheel can generally comprise a transmission ratio with which a force transmission of the at least one force storage device to the at least one actuating arm can be generated in a particularly favorable manner for a force-saving movement of the movable furniture part.

[0022] The at least one gearwheel can convert a linear movement and / or a pivoting movement—initiated by the at least one force storage device—into a rotational movement of the at least one actuating arm. However, the at least one actuating arm can generally also comprise linear motion sequences.

[0023] Advantageously, it is provided that the at least one adjusting device has at least one transmission means, wherein the at least one force storage device can be arranged on the at least one transmission means and / or the at least one transmission means can be arranged on the at least one actuating arm, preferably via a control cam of the at least one transmission means.

[0024] The at least one transmission means allows a point of application of the at least one force storage device on the at least one actuating arm to be shifted, whereby a modified force arm acts from the at least one force storage device on the at least one actuating arm and an increased or reduced force for moving the movable furniture part can be generated. Furthermore, the at least one force storage device can already be in a partially unloaded state or have an increased preload due to the modified point of application, so that force transmission to the at least one actuating arm can be adapted depending on the requirements of the movable furniture part.

[0025] A control cam can be used to particularly favorably manipulate a force transmission to the at least one actuating arm during a movement of the at least one actuating arm, wherein the control cam particularly preferably has at least two regions of different geometry, such as curvature or gradient, in order to be able to particularly advantageously influence a force effect curve. In general, however, the control cam can also be in the form of a bulge, so that the at least one actuating arm is moved in a defined manner by the at least one adjustment device and / or is positioned in a defined manner relative to the at least one adjustment device during a movement of the at least one actuating arm.

[0026] It has proven advantageous that the at least one force storage device can be moved, preferably via an adjusting device, along an engagement line of the at least one adjusting device, preferably of at least one transmission means that may be present, in order to change a force transmission torque on the at least one actuating arm, wherein the at least one adjusting device can be moved, preferably translationally, via the at least one adjusting device.

[0027] The adjusting device particularly preferably acts as a coupling element between the at least one adjusting device and the at least one force storage device, wherein a relative position between the at least one force storage device and the at least one adjusting device can be adjusted via the at least one adjusting device in order, for example, 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 provided that at least one damping device is arranged on the housing, which damping device can be arranged or is arranged on the at least one adjusting device, the at least one force storage device and / or the at least one actuating arm.

[0029] The at least one damper device can achieve a harmonious movement of the at least one actuating arm, whereby abrupt movements which can damage components of the furniture drive are prevented.

[0030] It has proven advantageous that the at least one display device can be arranged at least in regions on the at least one force storage device and / or the at least one adjustment device, wherein 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 contact the at least one force storage device, for example, indirectly via the adjustment device. In general, it is also conceivable for the at least one display device to be arranged, preferably indirectly, on the at least one force storage device or the at least one adjustment device, wherein a change in the force setting is transmitted to the at least one display device.

[0032] An advantageous variant consists in that the at least one display device is rotatably mounted on the housing and / or the at least one adjustment device.

[0033] This makes it possible to translate a change in the force setting 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 circumference, which can be rotated or pivoted relative to a component of the furniture drive, whereby the force setting can be read from the relative position of the scale to the component.

[0034] It is particularly preferred that the at least one display device is arranged at least partially, preferably completely, within the housing, wherein it is preferably provided that the at least one display device can be read through at least one opening of the housing.

[0035] This allows the kinematics of the display device to remain hidden within the housing and only the information required for force adjustment is accessible to a user of the furniture drive.

[0036] In one embodiment of the invention, it is provided that the at least one display device comprises at least one, particularly preferably curved, plate-shaped extension, preferably in the form of a metallic sheet metal part, for translating a force setting of the at least one setting device to the at least one display device.

[0037] By means of a curvature of the at least one plate-shaped extension, a translation of the force setting onto a scale to be read can be achieved particularly favorably by an interaction of the at least one force storage device and / or the at least one adjustment device and the at least one plate-shaped extension upon contact during a movement - initiated by the at least one adjustment device.

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

[0039] It has proven advantageous that the at least one display device comprises at least one scale, wherein the at least one scale is movable relative to the housing when the force that can be exerted by the at least one force storage device on the at least one actuating arm is adjusted by the at least one adjusting device, wherein it is preferably provided that the at least one scale is curved, particularly preferably convex.

[0040] In the prior art, a scale is arranged on the housing, whereby the scale must be very long in order to be able to display wide ranges of a force setting. A reduction in the number of visible parts for determining the force setting is offered by the solution with a scale arranged on the at least one display device, wherein preferably only that area of ​​the at least one scale is visible which is necessary for determining the force that can be exerted by the at least one force storage device on the at least one actuating arm. This can be ensured, for example, by at least one opening in the side of the housing through which only the relevant partial area of ​​the at least one scale can be read.

[0041] Furthermore, it is preferably provided that the at least one scale and the at least one plate-shaped extension are spatially separated from one another.

[0042] According to an advantageous embodiment of the invention, it is provided that the housing comprises at least one marking with which a force adjustment that can be carried out by means of the at least one adjustment device can be read by a relative position of the at least one display device, preferably at least one scale that may be present, to the at least one marking

[0043] The at least one marking and / or the at least one scale can be embossed, punched, drilled, glued, painted, engraved or the like, for example.

[0044] In a further embodiment, it can be provided that the at least one adjusting device comprises an adjusting device, preferably in the form of a tool holder, particularly preferably one that can be actuated from the front, wherein the setting of the force that can be exerted by the at least one force storage device on the at least one actuating arm can be adjusted via the adjusting device.

[0045] The adjustment device allows the force setting to be adjusted to the desired force setting in a user-friendly manner - for example by operating the tool holder with a screwdriver.

[0046] Further details and advantages of the present invention are explained in more detail below with reference to the exemplary embodiments shown in the drawings. Fig. 1a-1b shows a furniture drive according to a preferred embodiment with an adjustment device arranged between an actuating arm and a force storage device as well as a display device in a first force setting, wherein a side surface of the housing is removed for illustration in a perspective view and an enlarged detail section of the perspective view, Fig. 2a-2b shows the furniture drive according to the embodiment according to Fig. 1a in a second force setting in a perspective view and an enlarged detail of the perspective view, Fig. 3 the furniture drive according to the embodiment according to Fig. 2a in a further perspective view with an enlarged detail of a bottom side of the housing, Fig. 4 the furniture drive according to the embodiment according to Fig.1a in a further perspective view with an enlarged detail of the underside of the housing, Fig. 5a-5b an exploded view of components of the adjustment device, the display device and the housing and an enlarged view of the display device in a perspective view, Fig. 6a-6b the adjustment device, the display device and part of the housing of the furniture drive according to Fig. 1a in a side view and a view from below with an enlarged detail of the display device, Fig. 7a-7b the adjustment device, the display device and part of the housing of the furniture drive according to Fig. 2a in a side view and a view from below with an enlarged detail of the display device, Fig. 8 a piece of furniture according to a preferred embodiment with a furniture drive according to the embodiment according to Fig. 1a in a perspective view, Fig. 9 the furniture according to the embodiment according to Fig. 8 in another perspective view.

[0047] Fig. 1a shows a furniture drive 1 for moving a furniture part 3 which is mounted movably relative to a furniture body 2, comprising a housing 4 which can be arranged on a furniture panel 5 of the furniture body 2, an actuating arm 6 which is mounted movably relative to the housing 4 and a force storage device 7 with which a force can be exerted on the actuating arm 6.

[0048] The furniture drive 1 has an adjusting device 8 for adjusting the force that can be exerted by the force storage device 7 on the actuating arm 6, wherein a display device 9 is provided with which a force setting that can be carried out by means of the adjusting device 8 can be displayed.

[0049] The housing 4 of the furniture drive 1 has a contact surface 31 with which the furniture drive 1 can be brought into contact with the furniture panel 5. The housing 4 has a housing side 32 oriented transversely to the contact surface 31, wherein the display device 9 is arranged relative to this at least one housing side 32 in such a way that the display device 9 can be read when viewing the at least one housing side 32.

[0050] Fig. 1b shows a section of the furniture drive according to Fig. 1a shown enlarged, wherein it can be seen that the display device 9 is designed separately from the adjustment device 8, the force storage device 7, and the actuating arm 6. The display device 9 is rotatably mounted on the adjustment device 8 and contacts the force storage device 7 via an adjusting device 17.

[0051] The adjusting arm 6 comprises two gears 12 for moving the adjusting arm 6 from a first relative position into a second relative position separate from the first relative position, whereby a movement of the adjusting arm 6 between an open position of the movable furniture part 3 into a closed position and vice versa is possible. A gear 12 contacts the adjusting device 8 directly via a control cam 16 in the form of a bulge of a transmission means 15 of the adjusting device 8. The transmission means 15 can generally also comprise a control cam 16, which enables a modified force transmission to the movable furniture part 3 via a change in the relative position.

[0052] The transmission means 15 of the adjustment device 8 contacts the force storage device 7, wherein the force storage device 7 is translationally movable via the adjustment device 17 along an engagement line 18 of the transmission means 15 of the adjustment device 8. The translational movement can generally be superimposed with a pivoting movement. By moving the adjustment device 17 along the engagement line 18, a force transmission torque to the actuating arm 6 is changed, since the engagement point of the force storage device 7 is displaced relative to the actuating arm 6.

[0053] The adjustment device 17 is translationally movable via the adjustment mechanism 8, with the furniture drive 1 being in a first force setting and the force storage device 7 engaging the transmission means 15 at the top of the illustration. This corresponds to a low force setting.

[0054] Fig. 2a shows the furniture drive 1 in a modified force setting with a relative to Fig. 1a increased force transmission of the force storage device 7 to the actuating arm 6, wherein the force storage device 7 acts on the transmission means 15 at the bottom of the illustration and transmits force to the actuating arm 6 via the force adjustment device 8.

[0055] A damper device 19 is arranged on the housing 4, which, during a damping movement, is arranged on the actuating arm 6 and indirectly on the adjustment device 8. In general, however, the damper device 19 can also be arranged on the force storage device 7.

[0056] The display device 9 is rotatably mounted on the housing 4 via the further housing side 27 (not shown for reasons of clarity) and on the adjustment device 8. In general, the display device 9 can also be arranged on the force storage device 7.

[0057] The display device 9 is made entirely of metal.

[0058] The adjusting device 8 is arranged on the force storage device 7 via the adjusting device 17 and on the actuating arm 6 via the transmission means 15.

[0059] Fig. 2b differs from Fig. 2a only in the sense that an enlarged section of the furniture drive 1 is shown.

[0060] If the display device 9 moves during a movement of the actuating arm 6 - for example, when the opening angle of the movable furniture part 3 changes - it is possible that the display device 9 is moved relative to the housing 4, so that a force setting made via the adjusting device 8 is displayed in a varying manner on the display device 9. However, this does not pose a problem, since a user of the furniture drive only needs to read the force setting of the furniture drive 1 for a specific position of the actuating arm 6 in order to be able to deduce the force setting. Consequently, a display on the display device 9 may not depend exclusively on the force setting of the adjusting device 8; however, it does provide information about the existing force setting.

[0061] In practice, it is of particular relevance how the force setting of two corresponding furniture drives 1 was carried out relative to one another. Accordingly, it is sufficient to compare the force setting via the display devices 9 of the two furniture drives 1 in any position of the actuating arms 6. If the information provided by the display devices 9 differs, the force setting of one of the two furniture drives 1 can be adjusted via the adjustment device 8 by adjusting the point of application of the force storage device 7 on the associated actuating arm 6, so that an identical force setting can be read off the display devices 9 for the same position of the actuating arms 6.

[0062] Fig. 3 shows the furniture drive 1 viewed from the housing side 32, wherein the display device 9 is arranged within the housing 4 and can be read through an opening 29 in the housing 4. The shape of the opening 29 is generally arbitrary. In general, the display device 9 can protrude through the opening 29 or be located within the housing 4 and be visible through the opening 29; particularly preferably, the display device 9 is arranged in the opening 29.

[0063] The display device 9, which is separate from the housing 4, comprises a scale 21, wherein the scale 21 is moved relative to the housing 4 by the adjustment device 8 when the force exerted by the force storage device 7 on the actuating arm 6 is adjusted. The scale 21 has a convex curve. The scale 21 is independent of the housing 4, but a scale 21 arranged on the housing side 32 is also conceivable, wherein a force setting can be read from an underside of the housing 4 via a relative position of the display device 9—for example, by a marking on the display device 9—relative to this scale 21.

[0064] The housing 4 comprises two markings 22 which are arranged on the housing side 32 and with which a force adjustment which can be carried out by means of the adjustment device 8 can be read by a relative position of the display device 9 via the scale 21 to the marking 22.

[0065] Fig. 4 shows the furniture drive 1, with the scale 21 opposite the markings 22 relative to the position in Fig. 3 is moving. Opposite Fig. 3 The force setting was changed via the adjustment device 8 by moving the force storage device 7 along the line of action 18 of the transmission means 15 via the adjustment device 17. The changed point of action of the force storage device 7 on the actuating arm 6 results in a different force transmission torque, whereby the force setting is increased (despite an increase in the preload of the force storage device 7).

[0066] The movement of the adjustment device 17 rotated the display device 9 and moved the scale 21 relative to the markings 22. A change in the point of application of the force storage device 7 is kinematically coupled to the movement of the display device 9.

[0067] The scale 21 has intervals, with a numerical number for interpreting the current interval being arranged on the scale 21 within each interval. In general, however, other representations of the current force setting are also conceivable, whereby the scale 21 is not limited to the force setting display shown.

[0068] The marking 22 is in the form of an engraved line; however, other markings such as glued-on arrows or pointers are generally possible, via which a force setting can be read by the display device 9.

[0069] Fig. 5a shows the structural design of some components which, according to the preferred embodiment of the furniture drive 1, are used to change and display the force setting.

[0070] The adjustment device 8 comprises a rolling element which contacts the adjusting arm 6 during a movement of the movable furniture and is rotatably mounted on the adjustment device 8.

[0071] Fig. 5b shows the display device 9 in an enlarged view, wherein the display device 9 comprises a curved plate-shaped extension 20 in the form of a metallic sheet metal part for translating the force setting of the setting device 8 to the display device 9.

[0072] The plate-shaped extension 20 is moved by a movement of the force storage device 7, preferably via the adjusting device 17, in a rotating manner relative to the setting device 8, whereby the scale 21 is moved relative to the opening 29.

[0073] A return element 30 with a free end is integrally connected to the indicator device 9, wherein the return element 30 urges the indicator device 9 toward an initial position unless the indicator device 9 is urged in an opposite direction by the adjustment device 8. For example, the indicator device 9 is moved from the initial position to a force adjustment position, wherein the return element 30 causes the indicator device 9 to return to the initial position as soon as the force adjustment position has been canceled.

[0074] The reset element 30 is resilient and arranged opposite the plate-shaped extension 20. The scale 21 is arranged parallel to the side of the reset element 30 on a web-shaped extension, wherein the scale 21 and the reset element 30 are connected to a hinge region of the display device 9 via a connecting element arranged between the reset element 30 and the scale 21 and the plate-shaped extension 20.

[0075] Fig. 6a shows the Fig. 5a shown components in an assembled state.

[0076] Fig. 6b shows the assembled components of the furniture drive 1 according to Fig. 6a looking towards the housing side 32. The scale 21 arranged on the display device 9 can be read through the opening 29, whereby the force setting can be determined.

[0077] Fig. 7a shows the components of the furniture drive 1 with a changed position of the display device 9 relative to the markings 22 of the housing 4.

[0078] The scale 21 and the plate-shaped extension 20 are spatially separated from each other.

[0079] In Fig. 7b It can be seen that a change in the force setting via the adjustment device 8 results in a changed relative position of the display device 9. If the adjustment device 17 is moved again to the force setting position identified with "3", the plate-shaped extension 20 (cf. Fig. 7a ) is also moved into this relative position of the display device 9 by the reset element 30, in that the reset element 30 is supported on the adjustment device 8. In general, however, the reset element 30 can also be supported on another component.

[0080] Fig. 8 shows a piece of furniture 25 with a furniture body 2 and a furniture part 3 which is mounted so as to be movable relative to the furniture body 2 and which is in the form of a furniture flap which can be pivoted about a horizontal axis relative to the furniture body 2 in the position of use of the furniture 25.

[0081] The piece of furniture 25 comprises a furniture drive 1, wherein the furniture body 2 comprises a vertically arranged furniture panel 5 and the housing 4 of the furniture drive 1 is arranged on the furniture panel 5. The furniture part 3 is fastened to the movably mounted actuating arm 6 of the furniture drive 1, wherein the furniture part 3 is movable relative to the furniture body 2 by the furniture drive 1.

[0082] The housing 4 comprises a further housing side 27, which is arranged parallel to the contact surface 31. One side 28 of the furniture drive 1 can be completely covered by the further housing side 27. The housing side 32 is arranged between the further housing side 27 and the contact surface 31.

[0083] Fig. 9 shows the furniture 25, wherein the adjustment device 8, in a use position 26 of the furniture drive 1, in which the housing 4 is arranged on the furniture panel 5 of the furniture body 2, can be actuated from an end face 13 via an end face opening 14 of the housing 4. The end face 13 is arranged transversely at a right angle to the contact surface 31 and the housing side 32.

[0084] The adjusting device 8 comprises an adjusting device 23 in the form of a tool holder 24 which can be actuated from the front, wherein the setting of the force which can be exerted by the force storage device 7 on the actuating arm 6 can be adjusted via the adjusting device 23.
