[0001] Furniture fitting for articulated connection of a movable furniture part to a furniture body

[0002] Description

[0003] The invention relates to a furniture fitting for articulatedly connecting a movable furniture part to a furniture body, comprising

[0004] - a lever arm which is adjustable and pivotably attached to a base element for moving the furniture part around an axis between an open position and a closed position and

[0005] - a damper arranged on the base element with a first damping element and a second damping element, which are adjustable in a damped manner relative to each other in order to dampen an opening movement and a closing movement of the lever arm.

[0006] Furniture fittings of the type mentioned above are used, for example, to attach movable furniture parts, in particular flaps, folding flaps, doors or the like, to a furniture body in an adjustable manner between a closed position and an open position.

[0007] WO 2022 / 082238 A1, for example, discloses a drive device for a movable furniture component, comprising a support that can be attached to a movable furniture body, an actuating arm device movably mounted on the support and connectable to the movable furniture component, and a power storage device with which the actuating arm device can be actuated with force. The drive device further includes a damping device with which the closing and opening movements of the actuating arm device can be dampened. The damping device can be actuated from the same side of the actuating arm device during both the opening and closing movements. The invention is based on the objective of providing a furniture fitting that, in a compact design, enables simple and flexible damping when adjusting the lever arm.

[0008] The problem is solved by a furniture fitting for articulatedly connecting a movable furniture part to a furniture body, comprising a lever arm which is pivotably attached to a base element for moving the furniture part about an axis of adjustment between an open position and a closed position. According to the invention, the furniture fitting has a damper arranged on the base element with a first damping element and a second damping element which are adjustable relative to each other in a damped manner in order to dampen an opening movement and a closing movement of the lever arm.According to the invention, the lever arm is articulated to the damper in such a way that the first damping element is subjected to force in a first damping direction during the opening movement of the lever arm from a first intermediate position of the lever arm until the open position is reached, and that the second damping element is subjected to force in a second damping direction opposite to the first damping direction during the closing movement of the lever arm from a second intermediate position until the closed position is reached.

[0009] Applying pressure to the respective damping elements to dampen the lever arm during both the opening and closing movements allows for a simple and compact design for the furniture fitting. Unlike applying pressure to the same damping element during both opening and closing movements, this eliminates the need for a complex lever arrangement with numerous interacting elements. This prevents the susceptibility to errors and resulting functional impairments associated with a large number of interacting elements. The damping elements can be easily and flexibly adjusted in the respective damping direction during either the opening or closing movement by coupling the damper to the lever arm.By applying force to the damping elements only from the first or second intermediate position, it can be ensured that the damper does not dampen the lever arm over the entire opening or closing movement. A furniture fitting, particularly a flap fitting, can be understood as a device with which the movable furniture part, for example, a flap, folding flap, door, or the like, can be articulated to the furniture body. A furniture body can be understood as a solid part that constitutes the actual form of the furniture, particularly without inserts such as doors or drawers. For example, the furniture fitting can be connected to a wall element of the furniture, such as a side panel of the furniture body, via the base element.

[0010] A hinged connection between two elements means that these elements are connected to each other at one or more joints in a way that allows them to move arbitrarily, for example, rotationally and / or linearly relative to each other.

[0011] The lever arm can be made of one or more parts. It pivots around its axis between the closed and open positions. In the closed position, the movable furniture component can be designed to close an interior compartment of the furniture body. In the open position, the lever arm is arranged so that the movable furniture component opens the interior compartment.

[0012] During the opening movement, the lever arm pivots around the axis from the closed position to the open position. Similarly, during the closing movement, the lever arm is moved around the axis from the open position to the closed position. Intermediate positions are defined as angular positions of the lever arm between the closed and open positions.

[0013] The damper is articulated to the lever arm in such a way that one of the damping elements is subjected to force during either the opening or closing movement. The damping elements are adjustable relative to each other. During the opening movement of the lever arm, the first damping element is subjected to force in the first damping direction from a first intermediate position of the lever arm until the open position is reached. During the closing movement of the lever arm, the second damping element is subjected to force in the second damping direction from a second intermediate position of the lever arm until the closed position is reached. The two damping directions are opposite, so that the damping elements are adjusted in the respective damping direction towards the other damping element.

[0014] The damper can be articulated to the lever arm in such a way that the opening movement of the lever arm is transmitted to the first damping element, applying force to it in the first damping direction, and that the closing movement of the lever arm is transmitted to the second damping element, applying force to it in the second damping direction. In this context, "applying force" means that the damping elements are set in motion in the respective damping direction. For example, during the opening movement of the lever arm in the first damping direction, the first damping element can be moved towards the second damping element.

[0015] The damper is designed such that the movement of the lever arm during both the opening and closing movements is dampened by the adjustment of the damping elements relative to each other. Preferably, the damper can be designed as a fluid damper, for example, an oil damper, but also as a gas damper, or as a ring spring damper. Preferably, the damper can have a damping medium, for example, a spring element or a fluid, arranged between the damping elements. Hydraulic oil, for example, can be used as the damping medium for the oil damper. Furthermore, the damper can have a damper housing to receive the damping medium.

[0016] The furniture fitting can include a force storage device for applying force to the lever arm in the direction of the open position. The force storage device is designed such that the lever arm is subjected to force to reach the open position. For example, the force storage device can include a spring element, in particular a flat spring.

[0017] In a possible further development, the damper can be arranged on the base element such that, during the closing movement of the lever arm, the first damping element is fixed in the second damping direction from the second intermediate position of the lever arm until the closed position is reached, and that the second damping element is fixed in the first damping direction during the opening movement of the lever arm from the first intermediate position until the open position is reached. During damping in the first damping direction until the open position is reached, i.e., during opening damping, the second damping element of the damper can be fixed relative to the base element, while the first damping element of the damper can be movable.During damping in the second damping direction until the closed position is reached, i.e., during closing damping, the first damping element of the damper can be stationary relative to the base element, while the second damping element can be movable. By fixing one of the damping elements to the base element or supporting it against the other damping element when it is adjusted in the respective damping direction, the opening and closing movement of the lever arm can be enabled in a particularly simple and reliable manner using only this single damper.

[0018] In a possible further development, the damper can be arranged on a damping unit with two spaced-apart stop surfaces and a driver adjustable between the stop surfaces, the driver being coupled at least indirectly to the lever arm. The stop surfaces can be arranged such that the driver can pivot about a pivot axis along a path of movement between the stop surfaces or rotate about a rotation axis between the stop surfaces. The stop surfaces can be, for example, flat or curved. Furthermore, the stop surfaces can be curved such that they merge into one another, i.e., that the stop surfaces form a clearance fit for receiving the driver.

[0019] The driver is designed and / or arranged on the damping unit such that the opening or closing movement of the lever arm is transmitted to the damper, thereby moving the damping elements in the first or second damping direction, respectively. During the movement of the lever arm, the driver comes into contact with one of the stop surfaces to transmit the movement of the lever arm to the damping unit. Preferably, the driver can be arranged on the damping unit such that a circumferential surface of the driver can be brought into contact with the stop surfaces.

[0020] The damping unit is designed such that the movement from the driver is transmitted via the stop surfaces to the damper and, in particular, to the damping elements themselves. The damping unit, with its driver interacting with the stop surfaces, enables a simple transmission of the lever arm's movement to the damper for adjusting the damping elements in the respective damping direction.

[0021] According to one possible embodiment, the stop surfaces can be arranged at such a distance from one another that the driver is adjustable between a first stop position, which defines the first intermediate position of the lever arm, and a second stop position, which defines the second intermediate position of the lever arm. The first stop position is assigned to a first stop surface, and the second stop surface is assigned to a second stop surface. The initial contact of the driver with the respective stop surfaces when assuming the stop positions defines the respective intermediate position of the lever arm. When the lever arm is moved between the respective intermediate position and the closed or open position, the driver remains in the respective stop position. In each stop position, the driver can be adjusted along the corresponding stop surface by moving the support body.

[0022] The drive element is adjustable between the stop positions relative to the support body. In each stop position, the drive element transmits the movement of the lever arm to the damper via contact with the stop surfaces. In a free range between the stop positions, the drive element is free to move, so the movement of the lever arm is not transmitted to the damper. The damper can be inactive between the intermediate positions. Alternatively, the intermediate positions can also be defined by the damper's mounting, in particular the mounting of the damping elements on the damping unit.

[0023] Because the actuator can pivot between the two stop positions on the stop surfaces, it is possible to easily and reliably adjust the lever arm between the intermediate positions without damping. This means the lifting arm is only damped after the actuator is in contact with the stop surfaces in one of the stop positions, allowing the movable furniture part to be quickly moved from the closed to the open position or vice versa, while still being dampened by the damper at the end of the closing or opening movement.

[0024] In one possible embodiment, the contact surfaces can be formed on a support body of the damping unit, wherein the support body is adjustably mounted on the base element along a longitudinal axis of the damper to actuate the damping elements. The support body can have two support elements arranged at a distance from each other, with the damper being arranged between the support elements. The support elements can preferably be arranged transversely, and in particular perpendicularly, to the longitudinal axis of the damper at a distance from each other. The support elements can each be identical. The support body can have at least one spacer element arranged between the support elements. Several spacer elements arranged at a distance from each other can also be provided.

[0025] At least one guide can be provided for mounting the support body on the base element. The guide can have a first bearing section arranged on the support body, which interacts with a second bearing section arranged on the base element. For example, the first bearing section can be formed as an elongated hole and the second bearing section as a guide element adjustable along the elongated hole, for example, as a projection extending from the base element. Alternatively, it is conceivable that the second bearing section can be formed as an elongated hole and the first bearing section as a guide element. Preferably, two or more guides can be provided.

[0026] In the stop positions, the actuator transmits the movement of the lever arm to the support body, thereby adjusting the support body along the longitudinal axis of the damper and applying force to the first or second damping element in the first or second damping direction until the open or closed position is reached. The support body thus allows for the damper to be actuated on both sides at the two damping elements in the first damping direction and the opposite second damping direction.

[0027] In one possible embodiment, the damping elements of the damper can each be adjustable on the base element along the damper's longitudinal axis between two end stops. The base element can have an opening for linear adjustment of the damping elements along the damper's longitudinal axis. The end stops can be formed at the ends of the openings, for example, by bendable tabs. When one of the damping elements is adjusted, the other damping element is supported against the end stop in the respective damping direction, so that the damping elements are adjustable relative to each other.

[0028] The support body can be adjustable along the longitudinal axis of the damper beyond the end stops of the damping elements. The damper can be adjustably mounted on the support body in a bearing opening. The support elements can each have a bearing opening, with the damper positioned between the support elements and projecting into each bearing opening. The damping elements can be subjected to force by drive surfaces spaced apart along the longitudinal axis of the damper.

[0029] The intermediate positions of the lever arm can be determined alternatively or additionally by the design of the stop surfaces, or by the design of the bearing opening. For example, the drive surfaces can be spaced apart in such a way that the support body is initially adjusted without applying force to the damping elements.

[0030] By making the damping elements between the end stops adjustable, it is easy to adjust the damping elements relative to each other during the opening or closing movement of the lifting arm.

[0031] According to a possible embodiment, the follower can be arranged on a lever, the lever being adjustably pivotably attached to the base element and connected to the lever arm. The lever can preferably be flat, meaning that its height and width are multiples of its thickness. Preferably, the lever can be connected to the lever arm in such a way that the opening and closing movements are transmitted to the lever and the follower arranged on the lever, respectively. The lever can preferably be positioned between the support elements of the support body. For example, the lever can be connected to the lever arm via another lever.

[0032] Following further development, the furniture fitting can incorporate a damping adjustment unit for adjusting the damping effect acting on the lever arm. This damping adjustment unit can be designed so that the damping effect of the damper can be adjusted, for example, in terms of damping force, at a damping start position relative to the position of the drive element relative to the stop surfaces, and / or with respect to a damping path, such as along the longitudinal axis of the damper. Using this damping adjustment unit, the furniture fitting can be easily and flexibly adapted to different furniture components, for example, those of different sizes or weights.

[0033] According to a possible further development, the damping adjustment unit can have a guide contour and an adjustment unit connected to the driver, arranged at a distance from the guide contour, for moving the driver along the guide contour. The guide contour and / or the driver can be designed such that the driver is adjustable along the guide contour. For example, the guide contour can be formed as a recess, i.e., a free area, of the lever. The driver can preferably be designed as a pin element and have a cylindrical shape. The driver can be designed such that it penetrates the guide contour.

[0034] The adjusting unit is designed and / or arranged on the lever such that the driver can be moved along the guide contour by actuating the adjusting unit. Furthermore, the adjusting unit is connected to the driver such that actuating or adjusting the adjusting unit moves the driver along the guide contour. Preferably, the adjusting unit can be connected to the driver via at least one coupling element. The coupling element can be arranged at one end on the driver and at the other end on the adjusting unit. For example, the coupling element can be connected to the driver and / or the adjusting unit by force-fit and / or positive-fit. The coupling element can preferably be flat, particularly like the lever.

[0035] In one possible embodiment, the adjusting unit can comprise a threaded spindle rotatably mounted about a longitudinal axis and a threaded nut connected to the drive lug and arranged on the threaded spindle. The threaded spindle can be rotatably mounted about the longitudinal axis in at least one bearing element on the lever. In this context, the longitudinal axis refers to the longitudinal axis of the threaded spindle. Preferably, the threaded spindle can be mounted in two bearing elements. The bearing elements are, for example, arranged in the region of the ends of the threaded spindle. For example, a plain bearing, a receptacle for rotatably mounting one end of the threaded spindle, and / or a rolling bearing can be provided as bearing elements for one or both ends of the threaded spindle.

[0036] The threaded spindle can preferably be arranged in a direction transverse to the longitudinal axis at a distance from the guide contour. To achieve a compact and, in particular, flat design of the furniture fitting, the lever can have a spindle receptacle, i.e., preferably a free area of ​​the lever, for arranging the threaded spindle.

[0037] The threaded nut can preferably be arranged behind the at least one bearing element on the threaded spindle, viewed from a first end of the threaded spindle. Preferably, the threaded nut can be adjustably arranged on the threaded spindle between the two bearing elements along its longitudinal axis. Preferably, the threaded nut can be connected to the coupling element in such a way that the threaded nut is secured against rotation about the longitudinal axis of the threaded spindle, and rotation of the threaded spindle about its longitudinal axis causes a linear adjustment of the threaded nut along its longitudinal axis. The threaded spindle and the threaded nut enable a particularly simple and compact design of the adjustment unit, and the connection of the threaded nut to the driver via the coupling element allows for simple and reliable adjustment of the driver relative to the stop surfaces.

[0038] The coupling element can be designed such that adjusting the threaded nut along the threaded spindle causes the driver to move along the guide contour. Preferably, the coupling element can be rotatably coupled to the driver and / or the threaded nut. For example, a clearance fit between the coupling element and the driver and / or the threaded nut can be provided for this purpose.

[0039] The damping adjustment unit can have two coupling elements arranged at a distance from each other on the lever. The coupling elements are preferably arranged at a distance from each other along a longitudinal axis of the driver. Particularly preferably, the coupling elements are arranged on opposite sides of the lever. Furthermore, the coupling elements can be identical and arranged congruently with each other.

[0040] According to one possible embodiment, the stop surfaces can be formed by a window-like recess such that adjusting the driver along the guide contour causes the driver to be adjusted relative to the first and / or the second stop surface of the recess in order to adjust the damping effect of the damper during the opening movement and / or during the closing movement of the lever arm.

[0041] The window-like recess is a free area of ​​the supporting body, particularly the supporting elements, in which the drive element can pivot. In this context, "window-like" means that the recess is bounded by the two stop surfaces and two boundary surfaces connecting these stop surfaces.

[0042] The driver can be adjusted along the guide contour and the window-like recess between a maximum and a minimum position. In either the maximum or minimum position, the driver can be positioned against a boundary surface and adjusted along this surface. The two stop surfaces can each be designed such that adjusting the driver between the maximum and minimum positions results in an adjustment of the driver relative to the respective stop surface.

[0043] It is also conceivable that one of the stop surfaces is designed such that adjusting the driver along the guide contour does not result in any adjustment of the driver relative to the stop surface. The design of the recess and the stop surfaces can determine whether the damping effect is adjustable in the first damping direction and / or in the second damping direction. Furthermore, at least two drivers can be provided. One of the two drivers can be fixed to the first lever to allow adjustment of only the opening damping or only the closing damping via the damping adjustment unit.

[0044] To adjust the damping effect of the damper on the lever arm during the opening or closing movement, a user can operate and / or adjust the adjustment unit, thereby moving the driver along the guide contour to change its position relative to the first and / or second stop surface. This sets the damping start positions for the closing and / or opening movement, as defined by the stop positions, and alternatively or additionally, the damping travel of the damper.

[0045] In a possible further development, the furniture fitting can include an adjusting unit for rotating the threaded spindle about its longitudinal axis. The adjusting unit can be designed such that actuating and / or adjusting, in particular rotating, the adjusting unit causes the threaded spindle to rotate about its longitudinal axis. The adjusting unit is preferably connected to the threaded spindle. Particularly preferably, the adjusting unit can have two engaging adjusting elements, wherein a first adjusting element is connected to an end section of the threaded spindle or is formed integrally with the threaded spindle, and a second adjusting element is rotatably mounted on the lever. The adjusting elements can form a gear drive for transmitting a rotary motion from the adjusting unit to the threaded spindle.

[0046] The two actuating elements can be designed and / or arranged such that the rotational movement of the second actuating element is redirected to the first actuating element and the associated threaded spindle. The second actuating element can be rotatably mounted on the lever about an axis of rotation arranged perpendicular to the longitudinal axis of the damper and / or parallel to the longitudinal axis of the driver. The axis of rotation of the second actuating element can be arranged transversely, in particular perpendicularly, to the longitudinal axis of the threaded spindle.

[0047] The first adjusting element can be arranged on a first end section of the threaded spindle located at the first end. Preferably, the first adjusting element can be arranged on the threaded spindle such that all bearing elements for rotatably supporting the threaded spindle in the direction of its longitudinal axis are located on one side of the first adjusting element. Particularly preferably, the first adjusting element can be arranged on an end face of the threaded spindle. Furthermore, the first adjusting element can be connected to the threaded spindle, for example, by a force-fit or positive-locking connection. The first adjusting element can preferably be designed as a gear.

[0048] The second actuating element can be arranged on the lever such that it can be operated from one of the support elements of the support body. Preferably, the second actuating element can be formed as a toothed disc. For example, the gear drive can be designed as a bevel gear drive, wherein, in particular, the first actuating element can be a pinion and the second actuating element a ring gear.

[0049] Rotating the second actuating element, and thus operating the adjustment unit, can preferably be done manually, for example by a user such as a technician. Preferably, the second actuating element can have an actuating section. For example, the actuating section can be designed such that a screwdriver can be positioned on the actuating section to rotate the second actuating element. In particular, the actuating section can be formed as a recess or slot. The base element can have a through-opening located in the area of ​​the actuating section, particularly one that is congruent with the actuating section, to allow easy access to the actuating section.

[0050] The actuator simplifies the operation of the adjustment unit. Furthermore, the actuators, in conjunction with the redirection of the rotary motion, contribute to an even more compact design of the furniture fitting and easier access to the actuator.

[0051] In a possible further development, the furniture fitting can have several recesses arranged at intervals along an indication axis on the base element to indicate the set damping effect. The recesses can be arranged at uniform intervals in the direction of the indication axis. The indication axis can preferably be located on a first surface of the base element that is parallel to the lever, in particular to the side surfaces of the lever.

[0052] The recesses can be formed as openings penetrating the base element. Particularly preferably, the recesses are formed such that the position of the threaded nut on the threaded spindle is identifiable. In addition to the recesses, information regarding the damping coefficient can be affixed, printed, and / or embossed onto the base element.

[0053] Particularly preferably, the lever can be pivotably attached to the base element such that the longitudinal axis of the threaded spindle is parallel to, and especially coincident with, the indicator axis of the recesses in the open position. It is also conceivable that the guide contour is arranged in the open position such that the position of the driver can be read from the recesses on the guide contour. The recesses and the advantageous arrangement of the first lever enable quick and easy detection of the position of the threaded nut. Furthermore, the accuracy of the damping effect setting can be improved by reading the set damping start position.

[0054] The invention further relates to a piece of furniture comprising a movable furniture part and a furniture fitting articulated to the furniture part. The furniture can, for example, be a wall cabinet for the kitchen. The movable furniture part can, for example, be a flap, in particular a folding flap with a lower and an upper flap element. The furniture fitting, in particular the flap fitting, can be connected to the base element on a wall element of the furniture, for example, a side panel.

[0066] Figure 11 shows a side view of a piece of furniture with a movable furniture part and the furniture fitting from Figures 1 to 8.

[0067] Figures 1 to 8 show a furniture fitting 1 with a lever arm 2, which is pivotably mounted on a base element 3 about an adjusting axis S2 between an open position, as shown in Figures 2 and 6, and a closed position, as shown in Figures 4 and 8. For clarity, the furniture fitting 1 is shown without a side panel that would enclose it. The furniture fitting 1 has a damping unit 4 with a damper 5 arranged on the base element 3, which has a first damping element 6 and a second damping element 7. The two damping elements 6 and 7 are adjustable with damping relative to each other in order to dampen the opening and closing movements of the lever arm 2.

[0068] The damping unit 4 further comprises a support body 8 and a window-like recess 9 with two spaced-apart stop surfaces 10, 11. A driver 12 of the damping unit 4 is arranged on a first lever 13, which is adjustably pivotably attached to the base element 3 and connected to the lever arm 2 via a second lever 14. The window-like recess 9 is a free area of ​​the support body 8 in which the driver 12 can pivot.

[0069] The support body 8 is adjustably mounted on the base element 3 in a direction along a longitudinal axis L5 of the damper 5 to actuate the damping elements 6, 7. For this purpose, at least one guide 16, or in this case, for example, two guides 16, are provided. The guides 16 each have a first bearing section 17 arranged on the support body 8, which interacts with a second bearing section 18 arranged on the base element 3. For example, the first bearing section 17 is formed as an elongated hole and the second bearing section 18 as a guide element adjustable along the elongated hole.

[0070] The damping elements 6, 7 of the damper 5 are each adjustable on the base element 3 along the longitudinal axis L5 of the damper 5 between a first end stop 41 and a second end stop 42. The base element 3 has an opening 19 for linear adjustment of the damping elements 6, 7 along the longitudinal axis L5 of the damper 5. The end stops 41, 42 are formed, for example, at the ends of the opening 19 by bendable tabs 20.

[0071] The damper 5 is adjustably mounted on the support body 8 in a bearing opening 21. The damping elements 6, 7 can each be acted upon by drive surfaces 22 arranged at intervals along the longitudinal axis L5 of the damper 5. Furthermore, the furniture fitting 1 has a damping adjustment unit 23 for adjusting the damping effect acting on the lever arm 2. The damping adjustment unit 23 has a guide contour 24 and an adjustment unit 25, arranged at a distance from the guide contour 24 and connected to the drive 12, for moving the drive 12 along the guide contour 24. The drive 12 is, for example, designed as a pin element.

[0072] The adjusting unit 25 has a threaded spindle 26 rotatably mounted on the first lever 13 about a longitudinal axis L26 and a threaded nut 27 arranged on the threaded spindle 26. The threaded spindle 26 is mounted on the first lever 13 in two bearing elements 28, 29. A first bearing element 28, in the form of a rolling bearing or sliding bearing, is arranged at a first end section 30 of the threaded spindle 26. A second bearing element 29, in the form of a receptacle, is arranged at a second end section 31 of the threaded spindle 26. For mounting the threaded spindle 26, the first lever 13 has a spindle receptacle 32, i.e., a free area extending between a first side surface 33 and a second side surface 34 of the first lever 13.

[0073] The threaded nut 27 is adjustably arranged on the threaded spindle 26 between the two bearing elements 28, 29 along the longitudinal axis L26. The adjusting unit 25 is connected to the driver 12 via a coupling element 35. The threaded nut 27 is connected to the coupling element 35 in such a way that the threaded nut 27 is secured against rotation about the longitudinal axis L26 of the threaded spindle 26, and rotation of the threaded spindle 26 about the longitudinal axis L26 causes a linear adjustment of the threaded nut 27 along the longitudinal axis L26.

[0074] The driver 12 is adjustable along the guide contour 24 and the window-like recess 9 between a minimum position, as shown in Figures 1 to 4, and a maximum position, as shown in Figures 5 to 8. In either the maximum or minimum position, the driver 12 can be positioned against one of the limiting surfaces 15 and be adjustable along this surface. The two stop surfaces 10, 11 can each be configured such that adjusting the driver 12 between the maximum and minimum positions results in an adjustment of the driver 12 relative to the respective stop surface 10, 11.

[0075] Furthermore, the damping adjustment unit 23 has an actuating unit 36 ​​arranged on the first lever 13 for rotating the threaded spindle 26 about the longitudinal axis L26. The actuating unit 36 ​​has two engaging actuating elements 37, 38. A first actuating element 37 is connected to the first end section 30 of the threaded spindle 26, and a second actuating element 38 is rotatably mounted on the first lever 13.

[0076] The actuating elements 37, 38 of the actuating unit 36 ​​form a gear drive for transmitting a rotary movement from the actuating unit 36 ​​to the threaded spindle 26. The first actuating element 37 is rotatable about the longitudinal axis L26 of the threaded spindle 26 and the second actuating element 38 is rotatably mounted on the first lever 13 about a rotational axis D38 arranged perpendicular to the longitudinal axis L26 of the threaded spindle 26.

[0077] The first adjusting element 37 is arranged on an end face 39 of the threaded spindle 26 and is connected to the threaded spindle 26 via a force-fit and / or positive-locking connection or is formed integrally with, or as a component of, the threaded spindle 26. The first adjusting element 37 is, for example, formed as a gear.

[0078] The second actuating element 38 is arranged on the first lever 13 such that it can be operated from the base element 3. Furthermore, the second actuating element 38 has an actuating section (not shown) in the form of a recess for a screwdriver. The second actuating element 38 is, for example, formed as a toothed disc.

[0079] Several recesses 40 are arranged at intervals along an indication axis A40 on the base element 3 (see Figure 11). The recesses 40 are arranged at equal intervals in the direction of the indication axis A40. The indication axis A40 is located in the first surfaces 41 of the base element 3, and the recesses 40 are formed as openings penetrating the base element 3. The first lever 13 is rotatably attached to the base element 3 such that the longitudinal axis L26 of the threaded spindle 26 is parallel and coincident with the indication axis A40 in the open position.

[0080] In addition to the recesses 40, information on the damping level, which is not shown, may be arranged.

[0081] The lever arm 2 is articulated to the damper 5 such that, during the opening movement of the lever arm 2, the first damping element 6 is subjected to force in a first damping direction DR1 from a first intermediate position of the lever arm 2, as shown in Figures 1 and 5, until the open position is reached, and that, during the closing movement of the lever arm 2, the second damping element 7 is subjected to force in a second damping direction DR2, opposite to the first damping direction DR1, from a second intermediate position, as shown in Figures 3 and 7, until the closed position is reached. The two damping directions DR1 and DR2 are opposite, so that the damping elements 6 and 7 are adjustable in their respective damping directions DR1 and DR2, respectively, towards the other damping element 6 and 7.During damping in the first damping direction DR1 until the open position is reached, i.e., during opening damping, the second damping element 7 of the damper 5 is stationary relative to the base element 3, and the first damping element 6 of the damper 5 is movable. During damping in the second damping direction DR2 until the closed position is reached, i.e., during closing damping, the first damping element 6 of the damper 5 is stationary relative to the base element 3, and the second damping element 7 of the damper 5 is movable.

[0082] The driver 12 is adjustable in the window-like recess 9 between a first stop position, as shown in Figures 1 and 5, which defines the first intermediate position of the lever arm 2, and a second stop position, as shown in Figures 3 and 7, which defines the second intermediate position of the lever arm 2. Here, for example, it can be pivoted. The first stop position is associated with a first stop surface 10, and the second stop position is associated with a second stop surface 11. In each stop position, the driver 12 transmits the opening or closing movement of the lever arm 2 to the support body 8. This causes the support body 8 to be linearly adjusted along the longitudinal axis L5 of the damper 5, and the first or second damping element 6, 7 is subjected to force in the first or second damping direction DR1, DR2 by the driver surfaces 22 until the open or closed position is reached.In a free area of ​​the window-like recess 9 between the stop positions, the driver 12 is freely movable, so that the movement of the lever arm 2 is not transferred to the support body 8 and the damper 5 is inactive.

[0083] To adjust the damping effect of the damper 5 on the lever arm 2 during the opening or closing movement, a user, for example a technician, can rotate the second adjusting element 38 around the axis of rotation D38 using a screwdriver (see Figure 9). This rotates the first adjusting element 37 and the threaded spindle 26 connected to the first adjusting element 37 around the longitudinal axis L26 of the threaded spindle 26. The rotation of the threaded spindle 26 causes a linear adjustment of the threaded nut 27 along the longitudinal axis L26, which in turn moves the driver 12 along the guide contour 24 via the coupling element 35. By changing the position of the driver 12 relative to the first and / or the second stop surface 10, 11, the damping start positions for the closing and / or opening movement and / or the damping path, as defined by the stop positions, are set.The user can read the set damping force from the recesses 40.

[0084] Figure 10 shows a second embodiment of the furniture fitting 1 shown in Figures 1 to 8. The same reference numerals are used for identical components or elements. The furniture fitting 1 shown in Figure 10 differs from the furniture fitting 1 shown in Figures 1 to 8 in the design of the support body 8.

The support elements 43 are arranged at a distance from each other perpendicular to the longitudinal axis L5 of the damper 5. The support elements 43 can each be identical. The support body 8 has at least one spacer element 44 arranged between the support elements 43. Here, for example, several spacer elements 44 are provided at a distance from each other. The support elements 43 each have a window-like recess 9 and a bearing opening 21.The first lever 13 is arranged between the support elements 43. The damping adjustment unit 23 has two coupling elements 35 arranged at a distance from each other on the first lever 13 along a longitudinal axis L12 of the driver 12. The coupling elements 35 are each arranged on the opposite side surfaces 33, 34 of the first lever 13.

[0085] Figure 11 shows a piece of furniture 45 with the furniture fitting 1 shown in Figures 1 to 4, here, for example, a flap fitting, with a flap 46 in the open position. The piece of furniture 45 comprises a side panel 47 and a top panel 48, which, together with a bottom panel 49, a back panel 50, and another side panel (not shown), define an interior space 51 of the piece of furniture 45. The interior space 51 of the piece of furniture 45 is accessible via an opening 52. The opening 52 is closed by the flap 46, which is pivotally connected at one end to the top panel 48 of the piece of furniture 45 by a hinge (not shown). In this case, the flap 46 comprises a lower flap element 54 and an upper flap element 55, which are connected to each other by another hinge (not shown). A fitting element 53 is rigidly connected to the flap 46. The fitting element 53 serves as a connecting element between the flap 46 and the furniture fitting 1 .The base element 3 can be connected to the side wall 47 via fastening elements not shown.

[0086] All features described in connection with individual embodiments of the invention can be provided in different combinations for the furniture fitting 1 and the furniture 45 in order to achieve their advantageous effects, even if these have been described for different embodiments. For example, the furniture 45 has a furniture fitting 1 as shown in Figure 9.
