[0001] Lever arm for a 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 articulately connecting a movable furniture part to a furniture body, comprising a lever element designed for articulated connection to a movable furniture part and having at least one locking recess.

[0004] 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.

[0005] For example, DE 10 2016 100 606 B3 discloses a lid adjuster with a base element and an adjusting arm that is pivotably attached to the base element about a pivot axis between a closed and an open position. The adjusting arm has a base element and a lever. The base element is subjected to force over part of the adjusting arm's pivot travel between the closed and open positions to move it into the open position. The lever can be fixed in at least one locking position relative to the base element by means of a detent mechanism, and the lever is pivotably connected to the base element.

[0006] The present invention is based on the objective of providing a lever arm which, with a simple and compact design, enables safe assembly and / or disassembly.

[0007] The problem is solved by a furniture fitting for articulatedly connecting a movable furniture part to a furniture carcass, comprising a lever element designed for articulated connection to a movable furniture part. The lever arm has a bearing plate rotatably connected to a base element of a furniture fitting and rotatably connected to the lever element about a pivot axis. According to the invention, a locking element is adjustably arranged on the bearing plate between a locking position that non-rotatably couples the bearing plate to the lever element and a release position that decouples the lever element from the bearing plate.

[0008] The rotating bearing plate relative to the lever element allows for simple and reliable securing of the lever element against unwanted rotation. If the lever element is not decoupled from the bearing plate, there is a risk that a furniture component connected to the lever arm, such as a lid, could spring open. The locking mechanism allows the lever element to be easily and quickly decoupled from the bearing plate during installation, thus reducing the risk of injury resulting from unwanted rotation of the lever element during assembly. It also enables quick and easy coupling of the bearing plate to the lever element after installation. Furthermore, the design, incorporating the bearing plate and the lever element, allows for a compact construction.

[0009] The lever element can be designed in one or more parts. Preferably, the lever element can be configured at a first end facing away from the bearing plate for articulated connection to a movable furniture part. An articulated connection between two elements means that these elements are connected to each other at one or more joints, allowing for any desired movement relative to each other, for example, rotationally and / or linearly.

[0010] The bearing plate can, for example, have a circular cross-section in a direction perpendicular to the axis of rotation. The bearing plate can be rotatably connected to the lever element such that a positive fit is formed between the bearing plate and the lever element in the radial and / or axial direction to the axis of rotation. For mounting the lever arm to a furniture fitting, the bearing plate can be rotatably connected to the base element of the furniture fitting. For example, the bearing plate can be detachably connected to the base element via a pivot bolt. The locking element is adjustably, and in particular pivotably, arranged on the bearing plate between the locking position and the release position. In the locking position, the locking element is connected to the lever element by frictional or positive locking, for example via a detent recess arranged on the lever element, such that the bearing plate is rotationally fixed to the lever element.In this context, "rotationally fixed" means that the bearing plate, together with the lever element, can rotate about the axis of rotation. In the locked position, the bearing plate cannot rotate relative to the lever element about the axis of rotation. The rotational movement of the bearing plate can be transmitted to the lever element in the locked position. Preferably, in the locked position, the locking element can form a positive fit with the detent recess in the circumferential direction of the bearing plate's axis of rotation.

[0011] In the release position, the locking element is no longer positively or force-fit connected to the lever element, thus decoupling the bearing plate from the lever element. "Decoupled" in this context means that the bearing plate and the lever element can rotate independently of each other about the axis of rotation. In the release position, the bearing plate can rotate relative to the lever element about the axis of rotation. The rotational movement of the bearing plate cannot be transmitted to the lever element in the release position. To mount the lever arm to a furniture fitting and / or a furniture fitting to a piece of furniture, the locking element is moved to the release position to prevent unwanted rotation of the lever element. After mounting, the locking element is moved from the release position to the locked position to couple the bearing plate to the lever element for use.The adjustment of the locking mechanism can be done manually by a user, for example a technician.

[0012] According to one possible embodiment, the bearing plate can be rotatably mounted in a receptacle arranged on the lever element. The receptacle can be located at one end of the lever element. Preferably, the receptacle can be located at a second end of the lever element, spaced apart from the first end.

[0013] The receptacle preferably has a cross-section adapted to the cross-section of the bearing plate, particularly one arranged perpendicular to the axis of rotation. In this context, "adapted" means that the cross-section of the receptacle is larger than the cross-section of the bearing plate such that the bearing plate is rotatably mounted in the receptacle. The receptacle is, for example, a free area of ​​the lever element used to mount the bearing plate.

[0014] The lever element can be flat at least at its second end, meaning that the lever element can have a longitudinal and lateral extent at least at its second end that corresponds to a multiple of the lever element's thickness. Particularly preferably, the lever element can have an annular end section that forms the contact surface. The annular end section is arranged at the second end of the lever element and is particularly formed integrally with the lever element. The annular end section can be designed such that it at least partially, particularly halfway, preferably three-quarters, and most preferably completely, encloses the bearing plate in the circumferential direction relative to the axis of rotation. The annular end section has a contact surface and an outer surface arranged at a distance from the contact surface.The contact surface can have an inner surface extending between the outer surface and the contact surface.

[0015] The detent recess can be arranged on the annular end section and / or the receptacle such that the locking element engages radially with the axis of rotation in the detent recess when in the locked position. The detent recess can, for example, be located on the inner surface of the receptacle. The locking element can preferably be pivoted about a pivot axis between the release position and the locked position. The receptacle allows the bearing plate to be mounted simply and reliably on the lever element. Furthermore, by forming the receptacle with an annular end section of the lever element, the bearing plate can be compactly accommodated within the lever element.

[0016] In a possible further development, the locking element can be adjustable between the locking position and the release position by means of an actuating element arranged on the bearing plate. The actuating element can, for example, be arranged on the bearing plate and / or on the lever element. Preferably, the actuating element can be designed such that the locking element is mechanically adjusted between the positions. The actuating element can have at least one actuating section for a user. For example, the actuating section can be designed as a recess for a screwdriver. Alternatively or additionally, the actuating section can be designed as a tab on the actuating section that can be folded about a hinge axis. The hinge axis can, for example, be arranged transversely, and in particular perpendicularly, to the axis of rotation of the bearing plate.

[0017] It is also conceivable that the actuating element has two actuating sections, with the first actuating section designed as a recess for a screwdriver and the second actuating section as a hinged tab. The locking element can, in principle, be adjusted directly between the release and locking positions. However, the actuating element provides the user with different options for adjusting the locking element, thus enabling flexible adjustment under varying spatial conditions. Depending on the available space, a user can, for example, use the first and / or the second actuating section to adjust the locking element.

[0018] According to one possible embodiment, the actuating element and / or the locking body can be designed such that the locking body is fixed in the locked position and / or the release position by the actuating element. The actuating element can be designed such that any adjustment, in particular pivoting, of the locking body from the locked position to the release position or vice versa is blocked.

[0019] Preferably, the actuating element can be rotatably mounted on the bearing plate about an axis of rotation, which is particularly located at a distance from the pivot axis. The axis of rotation of the actuating element can be parallel or, alternatively, transverse, particularly perpendicular to, the pivot axis of the locking element. Preferably, the actuating element can be rotatably mounted between a first operating position and a second operating position. In the first operating position, the actuating element locks the locking element in the locked position. Similarly, in the second operating position, the actuating element locks the locking element in the release position. By locking the locking element in the locked and / or release position, unwanted adjustment of the locking element can be prevented, thus eliminating the need for an additional locking element.This allows the risk of accidents caused by the lever arm to be further reduced in a simple way.

[0020] The actuating element can be designed such that adjusting the actuating element between its operating positions causes the locking element to move between the release position and the locking position. According to one possible embodiment, the actuating element can have a driver that interacts with at least one actuating surface on the locking element when the actuating element is adjusted. The driver can, for example, be integrally formed with the actuating element or detachably connected to it. The bearing plate and / or the actuating element can be designed such that the actuating element is guided on the bearing plate during adjustment, particularly rotation about the axis of rotation.

[0021] For example, the bearing plate can have a concave guide surface and the actuating element a convex sliding surface complementary to the concave guide surface. Furthermore, the driver can be designed as a projection extending radially from the sliding surface to the axis of rotation. The actuating element can be rotatably guided in a transverse direction, particularly perpendicular to the axis of rotation, between the bearing plate and the locking element.

[0022] Preferably, the actuating element can be mounted on the bearing plate such that rotating the driver with the actuating element about the axis of rotation relative to the actuating surface moves the locking element between the release position and the locking position. For example, the driver can be designed as a tab of the actuating element projecting towards the locking element. Preferably, the locking element can be arranged such that rotating the driver about the axis of rotation relative to the actuating surface or an actuating edge moves the locking element from the locking position to the release position, in particular pivoting it.

[0023] With at least two actuation surfaces, these can be arranged at a distance from each other on the locking element. Preferably, the locking element can have at least one guide for the driver, with the actuation surfaces preferably being arranged on the guide. The actuation surfaces can be arranged on the locking element, in particular on the guide, such that moving the driver between the two actuation surfaces along the guide moves the locking element between the release position and the locked position. The locking element can have a first actuation surface associated with the locked position and the first operating position, and a second actuation surface associated with the release position and the second operating position.The guide can be bent or curved in such a way that the actuator of the actuating element moves the locking body in a first pivoting direction when adjusting towards the first actuating surface and in a second pivoting direction when adjusting towards the second actuating surface. The advantageous design of the locking body and / or the actuating element allows for a particularly compact construction for the lever arm and, furthermore, enables simple and reliable adjustment and locking of the locking body.

[0024] In a possible further development, the locking element can be pre-tensioned towards the locking position, in particular by spring tension. A spring element can be provided on the locking element and / or on the actuating element. For example, the spring element can be designed as a torsion spring. Preferably, the spring element can be arranged on the locking element or the actuating element such that the locking element is spring-tensioned towards the locking position and / or the actuating element is spring-tensioned towards the first operating position. This allows the locking element to be automatically adjusted from the release position to the locking position for particularly simple and quick coupling of the bearing plate with the lever arm.

[0025] As previously explained, the lever element can have at least one detent recess into which the locking element engages in its locked position. In a further development, the lever element can have two detent recesses, and two locking elements, each corresponding to one of the detent recesses, can be adjustably arranged on the bearing plate between the locked and released positions. The detent recesses can be spaced apart from each other in the circumferential direction relative to the axis of rotation, and in particular, can be adjacent to each other. Alternatively, the two locking elements can also be arranged in a correspondingly larger detent recess. The actuating element can have two drivers for the locking elements, spaced apart from each other in the direction of the axis of rotation.

[0026] The spring element can be arranged such that both locking elements are biased towards the locking position. Preferably, the spring element can be arranged between the locking elements. In the locking position, the two locking elements are engaged with their detent recesses. Preferably, the locking elements can be identical, and particularly preferably, they can be arranged in a mirror-image configuration with respect to a radial axis of rotation. The actuating element can be arranged such that both locking elements are adjustable between the locking and release positions by means of the actuating element, in particular the actuator of the actuating element. The two locking elements enable a simple and compact design for the spring bias.

[0027] In one possible embodiment, the lever element, the bearing plate, the locking element, and / or the actuating element can be arranged flush with each other, at least in sections. Flush with the surface means that the lever element, the bearing plate, the locking element, and / or the actuating element are arranged at least in sections in a main plane. The main plane can be arranged transversely, and in particular perpendicularly, to the axis of rotation, the pivot axis, and / or the axis of rotation. Preferably, the annular end section of the lever element, the bearing plate, the locking element, and the actuating element can be arranged flush with the surface. Particularly preferable is the arrangement of the locking element and the bearing plate flush with the contact surface and the outer surface of the annular end section. The flush arrangement enables a particularly compact design for the lever arm.In a possible further development, the lever element can have several detents arranged circumferentially around the axis of rotation, and the bearing plate can have several detents, each corresponding to a detents, wherein the detents are adjustable between a detent position and a release position. The detents can preferably be different from, or alternatively identical to, the detent recess. Preferably, the detents can be smaller than the detent recesses. The detents can be designed to be complementary to the detents. The detents can be arranged on the inner surface of the receptacle, just like the detent recess. For example, at least three detents and three detents can be provided.

[0028] In the detent position, the detent elements are each engaged with a detent mark, so that the bearing plate is connected to the lever element via the detent elements in addition to the locking element, preventing rotation. In the release position, the detent elements are disengaged from the detent marks, so that the bearing plate can rotate about the axis of rotation relative to the lever element when the locking element is in the release position.

[0029] The locking elements can preferably be adjustable between the locking position and the release position when the locking element is in the release position. Particularly preferably, the bearing plate and / or the lever element can be designed such that the locking elements can be adjusted radially to the axis of rotation between the locking position and the release position by adjusting the bearing plate and / or the lever arm. Preferably, the bearing plate can be designed to be smaller than the receptacle such that the bearing plate is adjustable within the receptacle. The locking element, when in the locked position, can block the adjustment of the bearing plate within the receptacle. The additional locking elements, which are also released by the locking element to allow adjustment to the release position, further reduce the risk of accidents during the assembly of the lever arm.By adjusting the locking elements using the bearing plate, a further actuating element can be dispensed with.

[0030] In one possible embodiment, the bearing plate can be arranged along the axis of rotation between a base plate and a cover plate. The bearing plate, the locking element, and / or the actuating element can each be rotatably mounted on the base plate. For example, the base plate can have bearing bolts projecting along the axis of rotation for this purpose. The actuating element can alternatively or additionally be mounted on the cover plate. Preferably, the cover plate can have an end stop for the actuators of the actuating element. The cover plate can also provide information for an installer. For example, the cover plate can provide information on how to operate the actuating element. The base plate can be arranged on the bearing plate on the side of the contact surface of the annular end section, and the cover plate can be arranged on the bearing plate on the side of the outer surface of the annular end section.One or more fasteners, such as screws, may be provided to connect the bearing plate to the base plate and / or the cover plate. The base plate and cover plate allow for easy positioning of the lever arm on a furniture fitting, protect the bearing plate, and provide a way for the installer to quickly and easily display information, such as operating instructions or warnings, within the installation area. The ability to display warnings further reduces the risk of accidents.

[0031] The invention further relates to a furniture fitting, in particular a flap fitting, with a lever arm as described above, which is pivotably attached to the base element about an adjusting axis between an open position and a closed position, and a force storage device for applying force to the lever arm when it is moved from the closed position to the open position. The force storage device can, for example, be designed as a spring element. The lever arm is connected to the force storage device via the bearing plate. By making the bearing plate decoupleable from the lever element and rotatable relative to the lever element in the release position of the locking element and, optionally, in the release position of the detent elements, the force transmission or torque transmission to the lever element can be blocked.This prevents sudden and unexpected swiveling of the lever arm during the installation of the furniture fitting, for example, due to the energy storage device. After the furniture fitting has been installed on a piece of furniture, the installer can connect the lever element to the bearing plate, thereby transferring the torque from the energy storage device to the lever element.

[0032] Furthermore, the invention relates to a piece of furniture comprising a movable furniture part and a furniture fitting articulated to the furniture part. The furniture fitting, in particular 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 a furniture body of the furniture. A furniture body can be understood as a solid part constituting the actual form of the furniture, in particular without inserts such as doors or drawers.

[0033] The piece of furniture could be, for example, a wall cabinet for the kitchen. The furniture component could be, for example, a flap, in particular a bi-fold 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. By attaching the base element to a piece of furniture, the base element is fixed in place and has no degrees of freedom. The movable furniture component can be designed to close an interior compartment of the furniture in the closed position. In the open position, the lever arm is arranged such that the movable furniture component opens the interior compartment.

[0050] Figure 17 shows a side view of the lever arm of Figures 8 to 16 with a bearing plate rotated relative to a lever element.

[0051] Figure 1 shows a lever arm 1 according to the invention with a lever element 2 and a bearing plate 3 rotatably connected to the lever element 2 about a pivot axis D.

[0052] The lever element 2 is designed at a first end 4 facing away from the bearing plate 3 for articulated connection with a movable furniture part 33 and has an annular end section 6 at a second end 5 (see Fig. 2). The bearing plate 3 is rotatably mounted in a receptacle 7, formed by the annular end section 6 and arranged on the lever element 2 as shown in Figures 3 to 5. The annular end section 6 completely encloses the receptacle 7 circumferentially with respect to the axis of rotation D of the bearing plate 3. Furthermore, the annular end section 6 has a contact surface 8 and an outer surface 9 arranged at a distance from the contact surface 8. The receptacle 7 has an inner surface 10 extending between the outer surface 9 and the contact surface 8 (see Figure 2). The lever element 2 has a detent recess 11, which here, for example, is arranged on the inner surface 10 of the receptacle 7.The bearing plate 3 has a circular cross-section 12 in a direction perpendicular to the axis of rotation D. The lever arm 1 has a locking element 13 adjustably arranged on the bearing plate 3 between a locking position, as shown in Figures 2 and 3, and a release position, as shown in Figures 4 and 5. The locking element 13 is pivotable about a pivot axis S2 between the release position and the locking position and engages radially with respect to the axis of rotation D in the detent recess 11.

[0053] The locking element 13 is adjustable between the locking position and the release position by an actuating element 14 arranged on the bearing plate 3. The actuating element 14 has at least one, here for example two, actuating sections 15, 16. A first actuating section is designed as a recess 15 for a screwdriver and a second actuating section is designed as a hinged tab 16.

[0054] The actuating element 14 and the locking body 13 are designed such that the locking body 13 is fixed in the locking position and in the release position by the actuating element 14. To adjust the locking body 13, the actuating element 14 is rotatably mounted on the bearing plate 3 about a rotation axis R arranged at a distance from and parallel to the pivot axis S2 between a first operating position, as shown in Figures 2 and 3, and a second operating position, as shown in Figures 4 and 5.

[0055] The actuating element 14 is designed such that adjusting the actuating element 14 between the operating positions causes the locking body 13 to be adjusted between the release position and the locking position. For this purpose, the actuating element 14 has a driver 17 adjustable on the locking body 13 and two actuating surfaces 18, 19 for the driver 17.

[0056] The driver 17 is, for example, formed integrally with the actuating element 14, but can also be detachably connected to the actuating element 14. To guide the actuating element 14 during rotation about the axis of rotation R, the bearing plate 3 and the locking element 13 each have a concave guide surface 20, and the actuating element 14 has a convex sliding surface 21 complementary to the concave guide surfaces 20. Here, the driver 17 is designed, for example, as a projection extending radially from the sliding surface 21 towards the axis of rotation R.

[0057] The actuating surfaces 18, 19 are arranged at a distance from each other on a guide 22 of the locking body 13. A first actuating surface 18 is assigned to the locking position and the first operating position, and a second actuating surface 19 is assigned to the release position and the second operating position. The guide 22 is bent or curved such that the driver 17 of the actuating element 14 moves the locking body 13 in a first pivoting direction SR1 when moving towards the first actuating surface 18, and in a second pivoting direction SR2 when moving towards the second actuating surface 19 (see Figure 4).

[0058] In addition to the detent recess 11, the lever element 2 has several detent marks 23 arranged circumferentially around the axis of rotation D. The bearing plate 3 has several detent elements 24, each corresponding to a detent mark 23, which are adjustable between a detent position, as shown in Figures 2 to 4, and a release position, as shown in Figure 5. The detent elements 24 are each complementary to the detent marks 23. The detent marks 23, like the detent recess 11, are arranged on the inner surface 10 of the receptacle 7. The bearing plate 3 is designed such that the detent elements 24 can be adjusted radially relative to the axis of rotation D between the detent position and the release position by adjusting the bearing plate 3 in the receptacle 7 of the lever element 2. For this purpose, the bearing plate 3 is designed to be smaller than the receptacle 7, allowing it to be adjusted within the receptacle 7.

[0059] The annular end section 6 of the lever element 2, the bearing plate 3, the locking element 13, and the actuating element 14 are arranged flush with one another. This means that these components are arranged in a main plane H, which can be arranged, in particular, perpendicular to the axis of rotation D, the pivot axis S 13, and the axis of rotation R (see Figure 2). Furthermore, the locking element 13 and the bearing plate 3 are arranged flush with the contact surface 8 and the outer surface 9 of the annular end section 6. The bearing plate 3 is arranged in the direction along the axis of rotation D between a base plate 25 and a cover plate 26. The bearing plate 3, the locking element 13, and / or the actuating element 14 are each rotatably mounted on the base plate 25. For example, the base plate 25 has bearing pins 27 projecting in the direction along the axis of rotation D for the locking element 13 and the actuating element 14.The base plate 25 is positioned on the bearing plate 3 with respect to contact surface 8, and the cover plate 26 is positioned with respect to outer surface 9. One or more fasteners 28, such as screws or the like, are provided to connect the bearing plate 3 to the base plate 25 and / or the cover plate 26.

[0060] In the locked position, the locking element 13 and the detent elements 24 are each engaged with the detent recess 11 and the detent marks 23, so that the bearing plate 3 is rotationally fixed to the lever element 2. The locking element 13 is held in the locked position by the driver 17 of the actuating element 14, which is located on the first actuating surface 18 in the first operating position. To adjust the locking element 13 between the locked and released positions, a user can rotate the actuating element 14 from the first operating position to the second operating position at one of the actuating sections 15, 16. By rotating the actuating element 14 about the axis of rotation R, the driver 17 is moved along the guide 22 towards the second actuating surface 19, and the locking element 13 is moved in the second pivot direction SR2 from the locked position to the released position.The locking elements 24 are moved from the locking position to the release position by a radial displacement of the bearing plate 3 in the receptacle 7. In the release position, the bearing plate 3 is rotatable relative to the lever element 2 about the axis of rotation D. The locking element 13 is fixed in the release position by the driver 17 of the actuating element 14, which is arranged on the second actuating surface 19 in the second operating position.

[0061] For mounting the lever arm 1 on a furniture fitting 29, as shown in Figure 6, the bearing plate 3 is rotatably connected to a base element 30 of the furniture fitting 29. For example, the bearing plate 3 is detachably connected to the base element 30 via a pivot pin 31. The lever arm 1 is pivotably mounted on the base element 30 about an adjusting axis S1 between an open position and a closed position. The furniture fitting 29 further includes a force storage device (not shown) for applying force to the lever arm 1 when moving it from the closed position to the open position. The lever arm 1 is connected to the force storage device via the bearing plate 3.

[0062] Figure 7 shows a piece of furniture 32 with the furniture fitting 29 shown in Figure 6, here for example a flap fitting, with a movable furniture part 33, for example a flap in the open position. The piece of furniture 32 comprises a side panel 34 and a top panel 35, which together with a bottom panel 36, a back panel 37 and another side panel (not shown) define an interior space 38 of the piece of furniture 32. The interior space 38 of the piece of furniture 32 is accessible via an opening 39. The opening 39 is closed by the flap 33, which is pivotally connected to the top panel 35 of the piece of furniture 32 at one end by a hinge (not shown). In this case, the flap 33 comprises a lower flap element 40 and an upper flap element 41, which are connected to each other by another hinge (not shown). A fitting element 42 is fixedly connected to the flap 33.The fitting element 42 serves as a connecting element between the flap 33 and the furniture fitting 29. The base element 30 can be connected to the side wall 34 via fastening elements not shown.

[0063] To mount the lever arm 1 to the furniture fitting 29 and / or the furniture fitting 29 with the lever arm 1 to the furniture 32, the locking element 13 and the detent elements 24 are moved to the release position to prevent unwanted rotation of the lever element 2. After mounting, the locking element 13 is moved from the release position to the locked position, and the detent elements 24 are moved from the release position to the detent position to couple the bearing plate 3 to the lever element 2 for use. The adjustment of the locking element 13 and the detent elements 24 can be carried out manually by a user, as described above.

[0064] Figures 8 to 17 show a second embodiment of the lever arm 1 shown in Figures 1 to 7. The same reference numerals are used for identical components or elements. The lever arm 1 shown in Figures 8 to 17 differs from the lever arm 1 shown in Figures 1 to 7 by a different design of the bearing plate 3, the locking element 13, and the actuating element 14. Two identically shaped locking elements 13 are arranged on the bearing plate 3 in a mirror-image configuration with respect to a symmetry axis SA. For example, two detent recesses 11 are arranged on the inner surface 10, spaced apart from each other in the circumferential direction with respect to the axis of rotation D. Each of the two locking elements 13 is assigned to one of the detent recesses 11.

[0065] A spring element 43 is arranged between the locking elements 13 to bias the two locking elements 13 towards the locking position shown in Figures 8 to 11. The actuating element 14 is adjustable about the axis of rotation R, which is arranged perpendicular to the axis of rotation D, between the first operating position shown in Figures 8 to 10 and the second operating position shown in Figures 12 to 14. Two drivers 17, each in the form of a tab, are arranged on the actuating element 14.

[0066] Each of the locking elements 13 has an actuating surface 19. The actuating element 14 is mounted on the bearing plate 3 and the cover plate 26 such that rotating the driver 17 with the actuating element 14 about the axis of rotation R against the actuating surface 19 moves the locking elements 13 from the locked position to the release position, as shown in Figures 15 to 17.

[0067] To adjust the locking elements 13 between the locked and unlocked positions, a user can rotate the actuating element 14 from the first operating position to the second operating position. By rotating the actuating element 14 about the axis of rotation R, the driver 17 is moved against the actuating surfaces 19 of the locking elements 13, thereby moving the locking elements 13 from the locked position to the unlocked position. The detent elements 24 are moved by a radial displacement of the bearing plate 3 in the receptacle 7 from the detent position, as shown in Figure 16, to the unlocked position, as shown in Figure 17. In the unlocked position and the unlocked position, the bearing plate 3 is rotatable relative to the lever element 2 about the axis of rotation D. In the unlocked position, the locking elements 13 are biased by the spring element 45 in the direction of the locked position.All features described in connection with individual embodiments of the invention can be provided in different combinations for the lever arm 1, the furniture fitting 29 and the furniture 32 in order to realize their advantageous effects, even if these have been described for different embodiments.
