FURNITURE DRIVE FOR MOVING A FURNITURE PART MOVABLE RELATIVE TO A FURNITURE CARCASE

Description

[0001] The invention relates to a furniture drive for moving a furniture part that is movably mounted relative to a furniture body, in particular a furniture flap that is pivotable 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 movably mounted relative to the housing and to which the movable furniture part can be attached, 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 which is mounted to be movable relative to the furniture body, in particular at least one furniture flap which, in the operating position of the furniture, can be pivoted about a horizontal axis relative to the furniture body.

[0002] Such a furniture drive is already known from German patent application 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 by means of an application point 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] Further furniture drives are known from the documents US 2019 / 178916 A1, CN 210 768 305 U, DE 21 2017 000 269 U1 and WO 2016 / 077851 A1.

[0004] A disadvantage of the current state of the art is that contaminants can enter the furniture drive through the opening of the additional housing side, thereby posing a risk of impaired functionality and / or a reduced service life of the furniture drive. Furthermore, the aesthetic appearance of the furniture drive is diminished, and with a completely closed additional housing side, reading the force setting is only possible via a complex disassembly and subsequent reassembly of the additional housing side, without any reference to the scale.Furthermore, with tall furniture and / or furniture where furniture drives are located very low or are difficult to access, reading the force setting is difficult, in particular because differing viewing directions of users of different sizes - due to varying eye heights - generate considerable parallax effects when reading the force setting, which makes it impossible to achieve a sufficiently precise reading of the force setting.

[0005] The objective technical object of the present invention is therefore to provide a furniture drive that 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 improved appearance compared to the prior art and the possibility of more precise reading of the force setting.

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

[0007] According to the invention, 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 through at least one opening of this at least one housing side when looking at this at least one housing side, and wherein the at least one housing side is arranged on an underside of the housing as the lower wall of the housing of the furniture drive in a service position in which the furniture drive is arranged on the furniture panel, wherein the at least one display device is designed separately from the at least one adjustment device, and the at least one adjustment device can be actuated from an end face.

[0008] This makes it possible for at least one additional housing side, which, for example, is oriented parallel to the mounting surface, to be completely closed, thus preventing the ingress of contaminants into the furniture drive. If at least one housing side is located on the underside of the furniture drive in a working position where the furniture drive is positioned on the furniture panel, it can be particularly effectively prevented from dust and contaminants reducing the functionality and / or service life of the furniture drive.

[0009] In addition, there is the positive feature that the force setting can be read independently of the explicit design of at least one other side of the housing, whereby even with at least one other side of the housing completely closed, the force setting can be conveniently read by looking at at least one side of the housing.

[0010] Parallax effects can also be reduced particularly effectively.

[0011] As stated at the outset, protection is also sought for a piece of furniture with a furniture body and at least one furniture part that is movable relative to the furniture body, in particular at least one furniture flap that can be pivoted about a horizontal axis relative to the furniture body in the furniture's operating position, wherein the 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 attached or attachable to the at least one actuating arm of the at least one furniture drive, wherein the at least one furniture part is movable relative to the furniture body by the at least one furniture drive.

[0012] To identify the current force setting of the at least one furniture drive, it is only necessary that at least one side of the housing be accessible, allowing a user to obtain information about 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 enclosed to improve its aesthetic appearance, with the at least one display device being readable through at least one side of the housing and the force setting being adjustable via the front panel.

[0013] Advantageous embodiments of the invention are defined in the dependent claims.

[0014] If the force setting is manipulated via the front face by 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 by a screwdriver through the front face opening, with the at least one indicator device showing the changed force setting on the at least one side of the housing, which is particularly preferably inclined at a substantially 90 degrees to the front face. 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 by which at least one further housing side can be covered at least partially on one side of the furniture drive.

[0015] The at least one further housing side is neither required for force adjustment via the at least one adjustment device nor for reading the force setting 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 side of the housing can generally include, for example, bends and / or webs which, in addition to the side of the furniture drive, conceal further sides of the furniture drive, and / or be formed separately from or by the housing.

[0017] The at least one display device is spatially separate from the at least one adjustment device.

[0018] This allows at least one display device to be made of a different material, for example to reduce the weight of the furniture drive, and / or to be serviced in a particularly advantageous way when the at least one power storage device is changed.

[0019] Particularly preferably, the at least one display device is designed separately from the at least one energy 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 metallurgically bonded to the at least one adjustment device, the at least one energy storage device, the at least one actuating arm, and / or the transmission means.

[0020] According to an advantageous embodiment of the invention, the at least one adjusting arm comprises at least one gear for moving the at least one adjusting arm from a first relative position to 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. The at least one gear can generally include a transmission ratio with which a force transmission from the at least one energy storage device to the at least one adjusting arm can be generated in a manner particularly favorable for energy-efficient movement of the movable furniture part.

[0021] The at least one gear can transmit a linear motion and / or a pivoting motion – initiated by the at least one energy storage device – into a rotational motion of the at least one actuating arm. In general, however, the at least one actuating arm can also perform linear motion sequences.

[0022] Advantageously, it is provided that the at least one adjusting device has at least one transmission means, wherein the at least one energy storage device can be arranged on the at least one transmission means and / or the at least one transmission means can be arranged, preferably via a control cam of the at least one transmission means, on the at least one actuating arm.

[0023] 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, thereby changing the force arm acting on the at least one actuating arm and generating an increased or decreased force for moving the movable furniture part. Furthermore, the at least one force storage device can, due to the changed point of application, already be in a partially unloaded state or have an increased preload, so that the force transmission to the at least one actuating arm can be adapted according to the requirements of the movable furniture part.

[0024] A control cam can be used to manipulate force transmission to the at least one actuating arm in a particularly advantageous way during movement of the at least one actuating arm. The control cam preferably has at least two areas with different geometries, such as curvature or slope, in order to influence the force distribution particularly advantageously. In general, however, the control cam can also be in the form of a protrusion, such that the at least one actuating arm is moved by the at least one adjusting device in a defined manner and / or is positioned relative to the at least one adjusting device in a defined manner during movement of the at least one actuating arm.

[0025] It has proven advantageous that the at least one power storage device, preferably via an adjusting device, is movable along a line of action of the at least one adjusting device, preferably at least one transmission means if present, to change a force transmission torque on the at least one adjusting arm, wherein the at least one adjusting device is movable via the at least one adjusting device, preferably translationally.

[0026] The adjusting device particularly preferably acts as a coupling element between the at least one adjusting device and the at least one power storage device, wherein a relative position between the at least one power 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 power storage device relative to the at least one adjusting arm.

[0027] According to an advantageous embodiment of the invention, it is provided that at least one damper device is arranged on the housing, which can be arranged or is arranged on the at least one adjusting device, the at least one energy storage device and / or the at least one adjusting arm.

[0028] The at least one damping device enables a smooth movement of the at least one actuating arm, preventing abrupt movements that could damage components of the furniture drive.

[0029] It has proven advantageous that the at least one display device can be arranged at least partially on the at least one energy storage device and / or the at least one adjustment device, preferably being made entirely of metal.

[0030] The at least one display device can contact the at least one power storage device, for example indirectly via the adjustment device. In general, it is also conceivable that the at least one display device is arranged, preferably indirectly, on the at least one power storage device or the at least one adjustment device, whereby a change in the force setting is transmitted to the at least one display device.

[0031] An advantageous variant consists in the fact that the at least one display device is rotatably mounted on the housing and / or the at least one adjustment device.

[0032] This allows a change in force setting to be translated into a rotational movement of the at least one display device. For example, the at least one display device can have a circumferentially curved scale which is rotated or pivoted relative to a component of the furniture drive, so that the force setting can be read from the relative position of the scale to the component.

[0033] The at least one display device is arranged at least partially, preferably completely, inside the housing.

[0034] 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. In one embodiment of the invention, the at least one display device comprises at least one, preferably curved, plate-shaped extension, preferably in the form of a metallic sheet metal part, for translating a force adjustment of the at least one adjustment device to the at least one display device.

[0035] A translation of the force setting onto a readable scale can be achieved particularly favorably by means of a curvature of the at least one plate-shaped extension through 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.

[0036] According to a preferred embodiment of the invention, 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 energy storage device, preferably via at least one adjustment device that may be present and / or by rotation.

[0037] 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 by the at least one adjusting device when the force exerted by the at least one energy storage device on the at least one actuating arm is adjusted, wherein it is preferably provided that the at least one scale is, particularly preferably, convexly curved.

[0038] In the prior art, a scale is arranged on the housing, whereby the scale must be very long to be able to display a wide range of force settings. A reduction of visible parts for determining the force setting is offered by a scale arranged on the at least one display device, wherein preferably only that portion 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 portion of the at least one scale is readable.

[0039] Furthermore, it is preferably provided that the at least one scale and the at least one plate-shaped extension are spatially separated from each other.

[0040] According to an advantageous embodiment of the invention, the housing comprises at least one marking with which a force setting made by means of the at least one adjusting device can be read from the relative position of the at least one display device, preferably at least one scale if present, to the at least one marking.

[0041] The at least one marking and / or the at least one scale can be, for example, embossed, punched, drilled, glued, painted, engraved or the like.

[0042] 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, which is particularly preferably operable from the front, wherein the adjustment of the force exerted by the at least one energy storage device on the at least one adjusting arm can be set via the adjusting device.

[0043] The adjustment device allows the force setting to be adapted to the desired force setting in a user-friendly manner - for example, by actuating the tool holder with a screwdriver.

[0044] Further details and advantages of the present invention are explained in more detail below with reference to the description of the figures and the exemplary embodiments shown in the drawings. These show: Fig. 1a-1 shows a furniture drive according to a preferred embodiment with an adjusting device arranged between an adjusting arm and a power 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.

[0045] Fig. 1a Figure 1 shows a furniture drive 1 for moving a furniture part 3 which is mounted to move 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 to move relative to the housing 4 and a force storage device 7 with which a force can be exerted on the actuating arm 6.

[0046] The furniture drive 1 has an adjusting device 8 for adjusting the force that can be exerted by the power storage device 7 on the actuating arm 6, wherein a display device 9 is provided with which a force setting made by means of the adjusting device 8 can be displayed.

[0047] 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 such that the display device 9 is readable when looking at the at least one housing side 32.

[0048] Fig. 1b shows a section of the furniture drive according to Fig. 1a The enlarged view shows that the display device 9 is designed separately from the adjustment device 8, the energy storage device 7, and the actuating arm 6. The display device 9 is rotatably mounted on the adjustment device 8 and contacts the energy storage device 7 via an adjustment mechanism 17.

[0049] The adjusting arm 6 comprises two gears 12 for moving the adjusting arm 6 from a first relative position to a second relative position separate from the first relative position, thereby enabling movement of the adjusting arm 6 between an open position of the movable furniture part 3 and a closed position, and vice versa. One gear 12 contacts the adjusting device 8 directly via a control cam 16 in the form of a projection of a transmission element 15 of the adjusting device 8. The transmission element 15 can generally also include a control cam 16, which enables a change in the force transmission to the movable furniture part 3 via a change in the relative position.

[0050] The transmission means 15 of the adjusting device 8 contacts the energy storage device 7, the energy storage device 7 being translationally movable via the adjusting device 17 along a line of action 18 of the transmission means 15 of the adjusting device 8. The translational movement can generally be superimposed with a pivoting movement. By moving the adjusting device 17 along the line of action 18, a force transmission torque on the adjusting arm 6 is changed, since the point of application of the energy storage device 7 is displaced relative to the adjusting arm 6.

[0051] The adjusting device 17 is translationally movable via the adjusting device 8, wherein the furniture drive 1 is in a first force setting and the force storage device 7 engages the transmission means 15 in the illustration above. This corresponds to a low force setting.

[0052] Fig. 2a shows the furniture drive 1 in a modified force setting with a relative to Fig. 1a increased force transmission of the power storage device 7 to the adjusting arm 6, wherein the power storage device 7 in the illustration below engages the transmission means 15 and transmits force to the adjusting arm 6 via the force adjusting device 8.

[0053] A damping device 19 is arranged on the housing 4, which, during a damping movement, is located on the actuating arm 6 and indirectly on the adjusting device 8. In general, however, the damping device 19 can also be arranged on the energy storage device 7.

[0054] The display device 9 is rotatably mounted on the housing 4 via the (not shown for clarity) further housing side 27 and on the adjustment device 8. In general, the display device 9 can also be arranged on the energy storage device 7.

[0055] The display device 9 is made entirely of metal.

[0056] The adjusting device 8 is arranged on the power storage device 7 via the adjusting device 17 and on the adjusting arm 6 via the transmission means 15.

[0057] Fig. 2b differs from Fig. 2a merely in that an enlarged section of the furniture drive 1 is shown.

[0058] If the display device 9 moves during a movement of the adjusting arm 6 – for example, when the opening angle of the movable furniture part 3 changes – it is possible that the display device 9 will move relative to the housing 4, so that a force setting made via the adjusting device 8 will be displayed differently 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 at a specific position of the adjusting arm 6 to be able to deduce the force setting. Therefore, a reading on the display device 9 does not necessarily depend solely on the force setting of the adjusting device 8; however, it does provide information about the current force setting.

[0059] In practice, it is of particular relevance how the force setting of two corresponding furniture drives 1 was carried out relative to each other. Accordingly, it is sufficient to compare the force setting of the two furniture drives 1 via the display devices 9 in any position of the adjusting arms 6, whereby if the display devices 9 show different information, the force setting of one of the two furniture drives 1 can be adjusted via the adjusting device 8 by adjusting the point of application of the force storage device 7 on the corresponding adjusting arm 6, so that an identical force setting can be read via the display devices 9 when the adjusting arms 6 are in the same position.

[0060] Fig. 3 Figure 1 shows the furniture drive 1 with a view towards the housing side 32, wherein the display device 9 is arranged inside 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 inside the housing 4 and be visible through the opening 29; it is particularly preferred that the display device 9 is arranged in the opening 29.

[0061] The display device 9, separate from the housing 4, comprises a scale 21. When the force exerted by the energy storage device 7 on the adjusting arm 6 is set, the scale 21 is moved relative to the housing 4 by the adjusting device 8. The scale 21 is convexly curved. The scale 21 is independent of the housing 4; however, a scale 21 arranged on the housing side 32 is also conceivable. In this case, a force setting can be read from the underside of the housing 4 via the relative position of the display device 9—for example, by a marking on the display device 9—relative to this scale 21.

[0062] The housing 4 includes two markings 22, which are arranged on the housing side 32 and with which a force setting made by means of the adjusting device 8 can be read by a relative position of the display device 9 via the scale 21 to the marking 22.

[0063] Fig. 4 shows the furniture drive 1, where the scale 21 is relative to the markings 22 in relation to the position in Fig. 3 is moving. Opposite Fig. 3 The force setting was changed via the adjusting device 8 by moving the force storage device 7 along the line of application 18 of the transmission means 15 via the adjusting device 17. The changed point of application of the force storage device 7 on the adjusting arm 6 results in a different force transmission torque, which increases the force setting (despite an increase in the preload of the force storage device 7).

[0064] The movement of the adjusting 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 energy storage device 7 is kinematically coupled to the movement of the display device 9.

[0065] Scale 21 has intervals, with each interval containing a numerical value for interpreting the current interval. However, other representations of the force setting are generally conceivable, and scale 21 is not limited to the force setting shown.

[0066] The marking 22 is in the form of an engraved line; however, other markings such as affixed arrows or pointers are generally possible, by which a force setting can be read via the display device 9.

[0067] Fig. 5a Figure 1 shows the constructive design of some components which, according to the preferred embodiment of the furniture drive 1, are used to change and display the force setting.

[0068] The adjusting device 8 comprises a rolling element which contacts the adjusting arm 6 when the movable furniture is moved and is rotatably mounted on the adjusting device 8.

[0069] Fig. 5b Figure 1 shows the display device 9 enlarged, 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 adjusting device 8 to the display device 9.

[0070] The plate-shaped extension 20 is moved by a movement of the power storage device 7 preferably via the adjusting device 17 in a rotating manner relative to the adjusting device 8, whereby the scale 21 is moved relative to the opening 29.

[0071] A return element 30 with a free end is materially connected to the display device 9, the return element 30 pushing the display device 9 towards a home position, unless the display device 9 is pushed in the opposite direction by the adjustment device 8. For example, the display device 9 is moved from the home position to a force adjustment position, and the return element 30 returns the display device 9 to the home position again as soon as the force adjustment position is released.

[0072] The return element 30 is spring-loaded and arranged opposite the plate-shaped extension 20. The scale 21 is arranged parallel to the side of the return element 30 on a web-shaped extension, the scale 21 and the return element 30 being connected to a hinge area of ​​the display device 9 via a connecting element arranged between the return element 30, the scale 21 and the plate-shaped extension 20.

[0073] Fig. 6a shows the in Fig. 5a The depicted component parts are shown in an assembled state.

[0074] Fig. 6b shows the assembled component parts of the furniture drive 1 according to Fig. 6a with a view towards the housing side 32. The scale 21 arranged on the display device 9 can be read through the opening 29, which allows conclusions to be drawn about the force setting.

[0075] Fig. 7a shows the component parts of the furniture drive 1 with a changed position of the display device 9 relative to the markings 22 of the housing 4.

[0076] The scale 21 and the plate-shaped extension 20 are spatially separated from each other.

[0077] In Fig. 7b It is evident that a change in the force setting via the adjusting device 8 results in a changed relative position of the display device 9. If the adjusting device 17 is again moved to the force setting position identified as "3", the plate-shaped extension 20 (cf. Fig. 7a The return element 30 also moves the indicator device 9 into this relative position by bearing against the adjusting device 8. In general, however, the return element 30 can also bear against another component.

[0078] Fig. 8 shows a piece of furniture 25 with a furniture body 2 and a furniture part 3 which is mounted to be movable relative to the furniture body 2 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.

[0079] The furniture 25 has a furniture drive 1, wherein the furniture body 2 has 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 attached to the movable 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.

[0080] The housing 4 comprises a further housing side 27, which is arranged parallel to the mounting surface 31. A 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 mounting surface 31.

[0081] Fig. 9 Figure 25 shows the furniture, wherein the adjusting device 8, in a service 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 right angles to the contact surface 31 and the housing side 32.

[0082] The adjusting device 8 comprises an adjusting device 23 in the form of a tool holder 24 that can be actuated from the front, wherein the force exerted by the power storage device 7 on the adjusting arm 6 can be adjusted via the adjusting device 23. Reference symbol list:
