DETAILED DESCRIPTION OF THE INVENTION

(11) FIG. 1a shows a furniture drive 1 for moving a furniture part 3 that is movably mounted relative to a furniture carcass 2, comprising a housing 4 which can be arranged on a furniture panel 5 of the furniture carcass 2, an actuating arm 6 that is movably mounted relative to the housing 4 and an energy storage device 7 with which a force can be exerted on the actuating arm 6.

(12) The furniture drive 1 has a setting device 8 for setting the force that can be exerted on the actuating arm 6 by the energy storage device 7, wherein a display device 9 is provided with which a force setting that can be set by the setting device 8 can be displayed.

(13) 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 also has a housing side 32 oriented transversely to the contact surface 31, and the display device 9 is arranged relative to the housing side 32 that the display device 9 can be read when looking in the direction of the housing side 32.

(14) FIG. 1b shows a partial area of the furniture drive according to FIG. 1a that is represented enlarged. Here, it can be seen that the display device 9 is formed separate from the setting device 8, the energy storage device 7, and the actuating arm 6. The display device 9 is mounted rotatably on the setting device 8 and contacts the energy storage device 7 by way of an adjustment device 17.

(15) The actuating arm 6 comprises two toothed wheels 12 for moving the actuating arm 6 from a first relative position to a second relative position separate from the first relative position. A movement of the actuating arm 6 is made possible between an open position of the movable furniture part 3 and a closed position, and vice versa. A first toothed wheel 12 contacts the setting device 8 directly by way of a control curve 16 in the form of an indentation in a transfer member 15 of the setting device 8. The transfer member 15 can generally also comprise a control curve 16, which makes a transmission of force to the movable furniture part 3 possible, which transmission is changed via a change in the relative position.

(16) The transfer member 15 of the setting device 8 contacts the energy storage device 7, and the energy storage device 7 can be moved in a translatory manner by the adjustment device 17 along an application line 18 of the transfer member 15 of the setting device 8. The translatory movement can generally be overlaid by a pivoting movement. Through a movement of the adjustment device 17 along the application line 18, a force transmission torque on the actuating arm 6 is changed, as the application point of the energy storage device 7 is displaced relative to the actuating arm 6.

(17) The adjustment device 17 can be moved in a translatory manner by way of the setting device 8, and the furniture drive 1 is present in a first force setting and the energy storage device 7 acts on the transfer member 15 at the top in the representation. This corresponds to a low force setting.

(18) FIG. 2a shows the furniture drive 1 in a changed force setting with an increased transmission of force of the energy storage device 7 to the actuating arm 6 relative to FIG. 1a. In this case, the energy storage device 7 acts on the transfer member 15 at the bottom in the representation and transmits force to the actuating arm 6 via the force setting device 8.

(19) Arranged on the housing 4 is a damping device 19, which is arranged on the actuating arm 6 and indirectly on the setting device 8 during a damping movement. However, the damping device 19 can generally also be arranged on the energy storage device 7.

(20) The display device 9 is rotatably mounted on the housing 4 by way of the further housing side 27 (not represented for reasons of clarity) and on the setting device 8. The display device 9 can generally also be arranged on the energy storage device 7.

(21) The display device 9 is formed completely from metal.

(22) The setting device 8 is arranged by the adjustment device 17 on the energy storage device 7 and by way of the transfer member 15 on the actuating arm 6.

(23) FIG. 2b differs from FIG. 2a only to the extent that an enlarged section of the furniture drive 1 is represented.

(24) If the display device 9 moves during a movement of the actuating arm 6for example, in the case of a changed opening angle of the movable furniture part 3it is possible that the display device 9 is moved relative to the housing 4, with the result that a force setting made by the setting device 8 is displayed in a varying manner on the display device 9. This does not pose a problem, however, as a user of the furniture drive only has to read the force setting of the furniture drive 1 in a specific position of the actuating arm 6 to be able to deduce the force setting. Consequently, a display on the display device 9 may by no means depend exclusively on the force setting of the setting device 8. However, the display device 9 provides information about the present force setting.

(25) In practice, it is particularly relevant how the force setting of two corresponding furniture drives 1 was undertaken relative to one another. It is accordingly sufficient to compare the force setting via the display devices 9 of the two furniture drives 1 with one another in a desired position of the actuating arms 6. In the case of different information through the display devices 9, the force setting of one of the two furniture drives 1 can be adapted by the setting device 8 by adjusting the application point of the energy storage device 7 on the related actuating arm 6, with the result that in the same position of the actuating arms 6, an identical force setting can be read through the display devices 9.

(26) FIG. 3 shows the furniture drive 1 when looking in the direction of 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 opening 29 is generally of any desired shape. The display device 9 can generally protrude through the opening 29 or be located inside the housing 4 and visible via the opening 29; the display device 9 is particularly preferably arranged in the opening 29.

(27) The display device 9, which is separate from the housing 4, comprises a scale 21. The scale 21 is moved relative to the housing 4 when the force that can be exerted on the actuating arm 6 by the energy storage device 7 is set by the setting device 8. The scale 21 is designed convexly curved. The scale 21 is independent of the housing 4, but a scale 21 arranged on the housing side 32 is also conceivable, by which a relative position of the display device 9for example, by a marking on the display device 9relative to this scale 21, a force setting can be read from an underside of the housing 4.

(28) The housing 4 comprises two markings 22, which are arranged on the housing side 32 and with which a force setting that can be made by the setting device 8 can be read by a relative position of the display device 9 via the scale 21 to the marking 22.

(29) FIG. 4 shows the furniture drive 1, wherein the scale 21 is moved by comparison with the markings 22, relative to the position in FIG. 3. Compared with FIG. 3, the force setting has been changed by the setting device 8 by displacement of the energy storage device 7 via the adjustment device 17 along the application line 18 of the transfer member 15. The changed application point of the energy storage device 7 on the actuating arm 6 causes a deviating force transmission torque, whereby the force setting is increased (despite an increase in the pretensioning of the energy storage device 7).

(30) Due to the movement of the adjustment device 17, the display device 9 was rotated and the scale 21 moved relative to the markings 22. A change of the application point of the energy storage device 7 is coupled kinematically to the movement of the display device 9.

(31) The scale 21 has intervals, wherein arranged within the respective intervals is a numerical figure for interpreting the present interval on the scale 21. Other representations of the present force setting are generally also conceivable, however, wherein the scale 21 is not restricted to the display of the force setting that is shown.

(32) The marking 22 in FIGS. 3 and 4 is in the form of an engraved line. However, other markings such as stuck-on arrows or pointers, for example, via which a force setting can be read through the display device 9, are also generally possible.

(33) FIG. 5a shows the constructional design of some components that are used according to the preferred embodiment of the furniture drive 1 for changing and displaying the force setting.

(34) The setting device 8 comprises a rolling element, which contacts the actuating arm 6 during a movement of the movable piece of furniture and is mounted rotatably on the setting device 8.

(35) FIG. 5b shows the display device 9 depicted in enlarged form, wherein the display device 9 comprises a curved plate-shaped extension 20 in the form of a sheet metal part for transmitting the force setting of the setting device 8 to the display device 9.

(36) The plate-shaped extension 20 is moved by a movement of the energy storage device 7 preferably by way of the adjustment device 17 in a rotating manner relative to the setting device 8, whereby the scale 21 is moved relative to the opening 29.

(37) A restoring element 30 with one free end is connected in a materially-bonded manner to the display device 9, wherein the restoring element 30 pushes the display device 9 in the direction of a starting position unless the display device 9 is pushed by the setting device 8 in an opposite direction. For example, the display device 9 is moved from the starting position into a force setting position, wherein due to the restoring element 30 the display device 9 returns again to the starting position as soon as the force setting position has been cancelled.

(38) The restoring element 30 is formed resiliently and arranged opposite the plate-shaped extension 20. The scale 21 is arranged in parallel laterally adjacent to the restoring element 30 on a rib-shaped extension, wherein the scale 21 and the restoring element 30 are connected to an articulated region of the display device 9 by way of a connecting element arranged between the restoring element 30 and the scale 21 and the plate-shaped extension 20.

(39) FIG. 6a shows the component parts represented in FIG. 5a in an assembled state.

(40) FIG. 6b shows the assembled component parts of the furniture drive 1 according to FIG. 6a when looking in the direction of 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 deduced.

(41) 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.

(42) The scale 21 and the plate-shaped extension 20 are formed spatially separate from one another.

(43) FIG. 7b shows that, due to a change of the force setting by the setting device 8, a changed relative position of the display device 9 exists. If the adjustment device 17 is displaced once more into the force setting position identified by 3, the plate-shaped extension 20 (cf. FIG. 7a) is moved by the restoring element 30 likewise into this relative position of the display device 9 by the restoring element 30 being supported on the setting device 8. The restoring element 30 can generally also be supported on another component part, however.

(44) FIG. 8 shows a piece of furniture 25 with a furniture carcass 2 and a furniture part 3 movably mounted relative to the furniture carcass 2 in the form of a furniture flap, which is pivotable about a horizontal axis relative to the furniture carcass 2 in a usage position of the piece of furniture 25.

(45) The piece of furniture 25 has a furniture drive 1, wherein the furniture carcass 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 fastened to the movably mounted actuating arm 6 of the furniture drive 1, wherein the furniture part 3 is movable by the furniture drive 1 relative to the furniture carcass 2.

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

(47) FIG. 9 shows the piece of furniture 25, wherein the setting device 8 can be actuated in a usage position 26 of the furniture drive 1, in which the housing 4 is arranged on the furniture panel 5 of the furniture carcass 2, from a front side 13 via a front side opening 14 in the housing 4. The front side 13 is arranged transversely at a right angle to the contact surface 31 and the housing side 32.

(48) The setting device 8 comprises an adjustment device 23 in the form of a tool receiver 24 that can be actuated from the front side, wherein the setting of the force that can be exerted on the actuating arm 6 by the energy storage device 7 can be set by way of the adjustment device 23.
