Description

[0001] Gear nut

[0002] The invention relates to a gear nut for the gear of a fitting arrangement of a window, a door or the like, in particular a lift-and-slide element, such as a lift-and-slide door or a lift-and-slide window.

[0003] Such gears for a lift-and-slide element are known, for example, from DE 10 2019 109 639 A1 or DE 10 2019 109 642 A1, where the gear nut of these gears is referred to as the input shaft. However, fitting assemblies for windows or doors whose sashes are opened by turning can also have similar gears that include a corresponding gear nut.

[0004] The gear nut is generally used to transmit manual actuation of an actuating element coupled to the gear nut, such as a handle, to an adjusting element of the respective fitting assembly, via which the fitting assembly can be adjusted between different states—for example, a locked or unlocked sash, or a raised or lowered sash. Typically, a rotational movement of the actuating element is converted into a translational movement of the adjusting element. The adjusting element can, for example, be a drive rod of the fitting assembly.

[0005] Since the forces applied by manual operation are transferred to the fitting assembly via the gear nut, it must be particularly robust. Conventional gear nuts are therefore solid. It is particularly common to manufacture the gear nut as a cast part. This allows for a high degree of strength of the gear nut. However, its production is comparatively material- and energy-intensive.

[0006] It is an object of the invention to provide a gear nut for the gear of a fitting arrangement of a window, a door or the like, in particular a lift-and-slide door or a lift-and-slide window, which can be manufactured comparatively easily and in a resource-saving manner and at the same time has reliable stability.

[0007] The object is achieved by a gear nut with the features of claim 1 and by a gear with the features of claim 15. Advantageous embodiments emerge from the subclaims, the present description and the figures.

[0008] The gear nut according to the invention is designed to be used in a gear of a fitting arrangement of a window, a door or the like, in particular a fitting arrangement of a lift-and-slide element, such as a lift-and-slide door or a lift-and-slide window.

[0009] According to the invention, the gear nut comprises a receptacle for an actuating element, which extends along a central axis of the gear nut, and a coupling section which is eccentric with respect to the central axis for the drive-effective coupling of the gear nut to an actuating element of the fitting arrangement.

[0010] The aforementioned receptacle preferably extends from the outside into the gear nut. In particular, the receptacle can extend through the gear nut. The receptacle then corresponds to a passage through the gear nut along the central axis.

[0011] The central axis can run centrally through the receptacle. In particular, a cross-section of the receptacle perpendicular to the central axis can be rotationally symmetrical with respect to the central axis. In this case, the receptacle does not necessarily have to have the cross-section over its entire extension along the central axis. The cross-section of the receptacle can be defined by the largest cross-section that an element can have continuously when fully inserted into the receptacle along the central axis or pushed through the receptacle. Preferably, the cross-section of the receptacle has 4-fold rotational symmetry with respect to the central axis. In particular, the cross-section can be at least substantially square.

[0012] The receptacle can be designed for the actuating element in such a way that the actuating element or at least a coupling section of the actuating element can be inserted into the receptacle, particularly along the central axis. Said actuating element can be, for example, a handle. The coupling section of the actuating element can be designed, for example, as a square rod. The receptacle can therefore be designed as a square receptacle.

[0013] The coupling section of the gear nut serves to drive-effectively couple the gear nut to an actuating element of the fitting assembly, so that an adjustment, in particular rotation, of the gear nut (by means of the actuating element) leads to an adjustment, in particular displacement, of the actuating element. Thus, a drive movement is transmitted from the gear nut to the actuating element. The coupling section of the gear nut does not necessarily have to be directly coupled to the actuating element; rather, the drive movement can also be transmitted via one or more components provided between the coupling section and the actuating element.

[0014] The adjusting element can, in particular, be a drive rod of the fitting arrangement. However, the adjusting element can also be formed by another adjustable mechanical element of the fitting arrangement. The respective position of the adjusting element can be decisive for the respective state of a sash of the window or door or the respective state of the lift-and-slide element. For example, the position of the adjusting element can define whether the sash is locked or unlocked or whether the lift-and-slide element is raised or lowered. For this purpose, the adjusting element can in turn transmit the drive movement, which it receives from the gear nut, to one or more locking elements, such as locking pins, or to one or more lifting elements, such as carriages.

[0015] According to the invention, the gear nut is designed in several parts and comprises a first nut plate, a second nut plate, and at least one spacer arranged between the two nut plates. In particular, the gear nut is designed in several parts precisely in that it comprises the first nut plate, the second nut plate, and the at least one spacer. The nut plates and the spacer are designed separately from one another, i.e. as separate components, in particular manufactured separately from one another. This does not, however, preclude the possibility that they can be arranged in direct contact with one another and / or (permanently) firmly connected to one another after their manufacture.

[0016] Unlike usual, the gear nut is not designed as a single, solid element, but rather consists of the aforementioned nut plates and the spacer arranged between them. It may also include additional elements. The spacer can be arranged between the two nut plates, particularly with respect to the central axis.

[0017] The multi-part design of the gear nut allows for the use of different materials for different parts of the gear nut. In particular, it may be sufficient for the stability of the gear nut if the two nut plates are made of a particularly strong material, while the spacer may have a lower strength. This allows for greater flexibility in the selection of the respective materials. Furthermore, the space between the nut plates does not necessarily need to be completely filled, thus saving material. Overall, the gear nut according to the invention can therefore be manufactured in a more resource-efficient manner than conventional gear nuts.

[0018] The first nut plate and the second nut plate can each be at least substantially flat. The nut plates can be largely plate-shaped overall. In particular, the nut plates can each extend along a respective plane with an at least substantially constant thickness (preferably exclusively except for the hub sections described below), wherein the two planes are preferably parallel to one another.

[0019] Furthermore, the first nut plate and the second nut plate can each be aligned perpendicular to the central axis. The planes along which the two nut plates extend are thus aligned perpendicular to the central axis.

[0020] Furthermore, the first nut plate and the second nut plate are preferably arranged spaced apart from one another along the central axis. In particular, the first nut plate and the second nut plate are not in direct contact with one another. However, the first nut plate and the second nut plate are preferably each in direct contact with the spacer. The space between the first nut plate and the second nut plate can function as a spacer precisely because it is arranged between the two nut plates and is in direct contact with both nut plates.

[0021] The first nut plate and the second nut plate can have the same outer contour (relative to a cross-section perpendicular to the central axis). With respect to this outer contour, the first nut plate and the second nut plate can also be arranged in alignment with one another along the central axis.

[0022] Furthermore, it is preferred that the first nut plate and the second nut plate are mirror-symmetrical to one another. In particular, the first nut plate and the second nut plate can also be arranged mirror-symmetrically to one another, namely preferably with respect to a mirror plane perpendicular to the central axis.

[0023] Furthermore, it is advantageous if the spacer is designed to be mirror-symmetrical. The spacer preferably has a mirror symmetry with respect to a mirror plane perpendicular to the central axis, in particular to the aforementioned mirror plane, with respect to which the first nut plate and the second nut plate can be arranged mirror-symmetrically to one another. Furthermore, the spacer can have a further mirror symmetry with respect to a mirror plane parallel to the central axis, in particular a mirror plane in which the central axis lies. Such symmetries facilitate the assembly of the gear nut, since the spacer can be arranged in several different orientations between the two nut plates.

[0024] Preferably, the gear nut is designed to be mirror-symmetrical overall, in particular with respect to a mirror plane perpendicular to the central axis, with respect to which the two nut plates can also be arranged mirror-symmetrically to one another and / or the spacer can be designed mirror-symmetrically.

[0025] According to an advantageous embodiment, the first nut plate and the second nut plate each comprise a metal sheet as the material. The metal sheet can, in particular, be a steel sheet, which allows for high strength of the nut plates. In particular, the first nut plate and the second nut plate can each consist entirely of a metal sheet, preferably a steel sheet. The use of a metal sheet as the material enables comparatively cost-effective production of the nut plates.

[0026] In particular, the first nut plate and the second nut plate can each be formed as a stamped part. In other words, the first nut plate and the second nut plate can each be produced by stamping. This simplifies the production of the nut plates and, in particular, also enables extensive automation of production. However, this does not preclude the possibility that the two nut plates may be additionally processed in other ways during their production, in particular by forming.

[0027] According to a further advantageous embodiment, the first nut plate and the second nut plate each have a through-opening, and the said receptacle for the actuating element is formed by the two through-openings. The through-openings preferably each have a cross-section that is rotationally symmetrical to the central axis (perpendicular to the central axis), which preferably has a 4-fold rotational symmetry. In particular, the two through-openings can have the same cross-section. The cross-section of the receptacle can be defined by the cross-section of the two through-openings. The receptacle for the actuating element does not necessarily have to be formed exclusively by the two through-openings. In principle, other elements can also be involved in the formation of the receptacle; however, they are not absolutely necessary.

[0028] Preferably, the two through holes are aligned along the central axis. A gap may be provided between them, since the receptacle in the area between the two nut plates does not necessarily need to be radially limited relative to the central axis.

[0029] According to an advantageous development, the through-openings each have an at least substantially circular inner contour in cross-section, which has regularly distributed notches, wherein the notches preferably represent the only exceptions to the otherwise circular shape of the respective through-opening. Due to the notches, the through-openings can each be designed to accommodate a polygonal rod, the side edges of which engage in a respective one of the notches, thus achieving a positive fit with respect to rotation about the central axis.

[0030] The number of notches can correspond to the number of the aforementioned rotational symmetry and can be four in particular. Each of the notches can have two side surfaces (aligned perpendicular to the central axis) that meet at an angle, wherein this angle is preferably 60° in the case of three notches, preferably 90° in the case of four notches, preferably 108° in the case of five notches, and preferably 120° in the case of six notches. The transition between the two side surfaces can also be rounded. According to a further advantageous embodiment, the first nut plate and the second nut plate each have a hub section that protrudes parallel to the central axis and has a circular outer contour in cross-section (perpendicular to the central axis), wherein the hub section preferably also has a circular inner contour in cross-section.At least with regard to their external shape, the hub sections each have a cylindrical shape, the cylinder axis of which coincides with the central axis. In particular, the hub sections can each be designed to be rotationally symmetrical with respect to the central axis.

[0031] The hub portion of the first nut plate and the hub portion of the second nut plate can protrude in particular in opposite directions, namely preferably pointing away from each other. This, together with the circular outer contour, allows the hub portions to serve as a rotatable support for the gear nut in a gear housing.

[0032] Furthermore, it is preferred that the hub sections each form a collar surrounding the aforementioned through-opening of the respective nut plate. This circumferential collar can, in particular, be directly adjacent to the respective through-opening. Such a collar surrounding a through-opening can be formed comparatively easily by collar drawing; in principle, formation by extrusion or other forming, preferably cold forming, is also conceivable.

[0033] According to a further advantageous embodiment, the spacer has at least two coupling extensions that protrude in opposite directions parallel to the central axis, one of which engages in a recess formed in the first nut plate, and the other of which engages in a recess formed in the second nut plate. Preferably, the spacer has four or more coupling extensions that protrude in pairs in opposite directions parallel to the central axis, with one coupling extension of each pair engaging in a recess formed in the first nut plate, and the other coupling extension of each pair engaging in a recess formed in the second nut plate.

[0034] The coupling extensions and their engagement in the aforementioned recesses of the nut plates serve to fix the spacer between the two nut plates and, in particular, to prevent rotation. This ensures that the spacer is reliably positioned in a defined alignment between the two nut plates.

[0035] According to a further advantageous embodiment, the spacer is made of plastic. For example, the spacer can be formed as an injection-molded part. This enables simple and cost-effective production of the spacer.

[0036] According to a further advantageous embodiment, the spacer is arranged such that it projects radially inward into the receptacle with respect to the central axis. The spacer can project into the receptacle in particular insofar as the cross-section of the receptacle, which is defined in particular by the (preferably identical) cross-sections of the through-openings of the two nut plates, is at least slightly reduced, i.e., narrowed, in the region between the two nut plates by the spacer. When looking into the receptacle along the central axis, the part of the spacer projecting into the receptacle is therefore visible.

[0037] The fact that the spacer projects into the receptacle can advantageously result in the actuating element (or its coupling section) inserted into the receptacle being forced radially inwards with respect to the central axis. This is because if the actuating element expediently has a cross-section that is essentially complementary to the cross-section of the receptacle, it must push the spacer radially outwards when inserted into the receptacle, so that the spacer presses against the actuating element in the opposite direction, i.e. radially inwards, due to its at least slight inherent elasticity. The actuating element is consequently clamped in the receptacle and is thus secured in the receptacle by a force fit. The clamping effect not only prevents play between the actuating element and the gear nut, but also annoying cracking noises that can otherwise occur when the actuating element is actuated.

[0038] The spacer preferably protrudes into the receptacle from at least two directions, in particular directions perpendicular to each other. In particular, the spacer can have one or more, preferably at least two, contact surfaces that protrude into the receptacle from a respective direction and are oriented perpendicular to the respective direction. When the actuating element is inserted into the receptacle, the spacer can then press flatly against the actuating element with these contact surfaces, so that, due to the flat contact, a reliable force connection is achieved even under torques about the central axis.

[0039] The coupling section, via which the gear nut can be drivingly coupled to the adjusting element of the fitting arrangement, can in principle be formed, for example, by a toothing formed on the gear nut. If the adjusting element is designed as a drive rod, the toothing can engage directly with a corresponding, in particular ladder-shaped, coupling section of the drive rod in order to displace the drive rod along its longitudinal extent when the gear nut is rotated. However, the coupling section can also be designed in various other ways. According to an advantageous embodiment, the coupling section is formed by a bolt that is aligned parallel to the central axis and connects the two nut plates to one another. The bolt can in particular be rotationally symmetrical to a bolt axis along which it extends, wherein this bolt axis is aligned parallel to the central axis.Furthermore, it can be provided that the two nut plates are firmly connected to one another via the bolt, in particular exclusively via the bolt, ie are secured against detachment from one another at least along the central axis.

[0040] The bolt can extend along said bolt axis from a first end portion to a second end portion and engage with the first end portion in a bore formed on the first nut plate and engage with the second end portion in a bore formed on the second nut plate.

[0041] According to an advantageous development, the bolt can be connected to the two nut plates by a riveted joint. For this purpose, the mentioned end sections can be riveted into the mentioned bore of the respective nut plate. For this purpose, it may be expedient for the bore to have a chamfer on the side facing away from the other nut plate.

[0042] Between the two said end sections, the bolt can have a middle section which has a larger diameter than the two end sections. As a result, the bolt can have an annular shoulder at each of the two transitions between a respective one of the end sections and the middle section. Preferably, the diameter of the middle section is larger than the diameter of the said bores in the two nut plates, so that the bolt with the two annular shoulders strikes a respective one of the two nut plates when it engages with a respective end section in the bore of the respective nut plate. In this respect, the bolt can function as a spacer. In particular, the bolt can basically form the said spacer.Preferably, however, it is provided in addition to the spacer mentioned, which it can support with regard to the function of keeping the two nut plates spaced apart from each other at a certain distance.

[0043] According to a further advantageous embodiment, a coupling lever is pivotably mounted on the coupling section of the gear nut about a pivot axis parallel to the central axis. In particular, the coupling lever can be pivotally connected to the coupling section of the gear nut. If the coupling section is formed by the aforementioned bolt, the pivot axis can, in particular, coincide with the aforementioned bolt axis of the bolt.

[0044] Preferably, the coupling lever extends at least substantially along a radial direction relative to the pivot axis and thus perpendicular to the central axis. The coupling lever can extend from a proximal end, where it is connected to the coupling section, to a distal end, where it is configured for coupling to the actuating element of the fitting assembly.

[0045] For the pivotable mounting of the coupling lever, the bolt can extend through a through-hole formed at the proximal end of the coupling lever. To further support the pivotability, a bearing sleeve can also be provided, which encloses the bolt and is arranged between the bolt and the through-hole.

[0046] According to an advantageous development, the coupling lever comprises a first lever plate and a second lever plate, wherein the two lever plates abut one another flatly at the proximal end of the coupling lever and are spaced apart from one another at the distal end. Similar to the nut plates, the lever plates can each be at least substantially flat, comprise a metal sheet, preferably a steel sheet, as their material, in particular consist of this material, and be designed as a stamped part or stamped-bent part.

[0047] The lever plates can each have a proximal section, along which they lie flat against one another, and a distal section, along which they are spaced apart from one another parallel to one another, wherein a step is formed between the proximal section and the distal section, by means of which step the proximal section and the distal section are offset parallel to one another. The step can, for example, be formed by two mutually opposite bends. The step does not necessarily have to be aligned vertically (parallel to the central axis), but can also run obliquely. The step preferably encloses an obtuse angle (in particular the same angle) with both the proximal section and the distal section.

[0048] At the distal end, the two lever plates (similar to the nut plates when the coupling section is designed as a bolt) can be connected to one another via a further bolt aligned parallel to the central axis. This further bolt can engage with end sections of its longitudinal extension along a bolt axis parallel to the central axis into a respective bore formed on a respective one of the two lever plates. A middle section of the further bolt between the two end sections can have a diameter that is larger than the diameter of the two end sections and also larger than the diameter of the bores in the lever plates. As a result, the further bolt has two annular shoulders with which it can bear against a respective one of the lever plates when its end sections engage in the bores in the lever plates.In this respect, the additional bolt can act as a spacer between the distal sections of the two lever plates. At the same time, the additional bolt can serve to couple the actuating element of the fitting assembly. In particular, the coupling lever can be coupled to the actuating element of the fitting assembly via the additional bolt.

[0049] The gear mechanism according to the invention for a fitting arrangement of a window, a door, or the like, in particular a lift-and-slide element, such as a lift-and-slide door or a lift-and-slide window, comprises a gear mechanism housing and a gear nut according to the invention, which can be designed in particular in one of the ways described above and is mounted in the gear mechanism housing so as to be rotatable about the central axis. For this purpose, the gear nut can be received, in particular with the aforementioned hub sections, in corresponding hub receptacles formed in the gear mechanism housing.

[0050] The invention is further explained below purely by way of example with reference to the figures.

[0051] Fig. 1 shows an embodiment of a gear nut according to the invention in a perspective view.

[0052] Fig. 2 shows the embodiment shown in Fig. 1 in a front view.

[0053] Fig. 3 shows the embodiment shown in Fig. 1 in an exploded view.

[0054] In each of the figures, the same embodiment of a gear nut 11 according to the invention is shown from a different viewing angle (Figs. 1 and 2) or as an exploded view (Fig. 3). The gear nut 11 is a gear nut 11 for a gear of a fitting arrangement of a window, a door or the like, in particular a lift-and-slide element, such as a lift-and-slide door or a lift-and-slide window. The gear nut 11 has a receptacle 13 for an actuating element (not shown), which can in particular be designed as a handle. In the embodiment shown, the receptacle 13 is designed to receive a coupling section of the actuating element, which is designed as a square rod. For this purpose, the receptacle 13 is designed as a square receptacle and extends along a central axis Z through the gear nut 11.

[0055] In addition, the gear nut 11 itself has a coupling section 15, which in the illustrated embodiment is designed as a bolt and serves to drive-effectively couple the gear nut 11 to an actuating element (not shown) of the respective fitting arrangement. The coupling section 15 is arranged eccentrically with respect to the aforementioned central axis Z.

[0056] The gear nut 11 comprises a first nut plate 17 and a second nut plate 19, each of which is at least substantially flat, aligned perpendicular to the central axis Z, and spaced apart from one another along the central axis Z. The two nut plates 17, 19 are each formed from a steel sheet by stamping. The two nut plates 17, 19 are formed and arranged mirror-symmetrically to one another with respect to a mirror plane perpendicular to the central axis Z. The gear nut 11 is also mirror-symmetrically formed with respect to the same mirror plane.

[0057] The two nut plates 17, 19 each have a through-opening 21 formed by punching. The through-opening 21 of the first nut plate 17 and the through-opening 21 of the second nut plate 19 are aligned with one another along the central axis Z, so that the aforementioned receptacle 13 is formed by the two through-openings 21. The through-openings 21 each have an at least substantially circular inner contour in cross-section, which, however, has four regularly distributed notches 23. This allows a square rod to extend through the two through-openings 21 of the two nut plates 17, 19 and overall through the gear nut 11, engaging with its longitudinal edges in the aforementioned notches 23.In this way, a reliable positive connection with respect to a torque about the central axis Z is achieved between the coupling section of the actuating element, which is designed as a square bar, and the gear nut 11, so that the gear nut 11 and the actuating element are coupled thereto for common rotation.

[0058] The first nut plate 17 and the second nut plate 19 each have a hub section 25 which has a circular outer contour in cross-section and forms a collar surrounding the through-opening 21 of the respective nut plate 17 or 19. The hub section 25 protrudes parallel to the central axis Z from the rest of the respective nut plate 17 or 19. In particular, the hub section 25 can be the only part of the respective nut plate 17 or 19 that protrudes from the otherwise flat, planar shape of the respective nut plate 17 or 19. The hub section 25 of the first nut plate 17 and the hub section 25 of the second nut plate 19 protrude in opposite directions, namely away from each other. In this way, the hub sections 25 can serve to rotatably mount the gear nut 11 in a gear housing (not shown) of a gear of the fitting arrangement.

[0059] The two nut plates 17, 19 are connected to one another via the aforementioned coupling section 15, which is designed as a bolt. For this purpose, the first nut plate 17 and the second nut plate 19 each have a bore 27 into which the bolt 15 engages with a respective end portion of its longitudinal extension and to which the bolt 15 is riveted to the respective nut plate 17 or 19 (in the figures, however, the bolt 15 is still shown unriveted). As a result, the first nut plate 17 and the second nut plate 19 are permanently connected to one another.

[0060] The gear nut 11 further comprises a spacer 29, which is formed as an injection-molded part made of a plastic material. The spacer 29 is arranged along the central axis Z between the two nut plates 17, 19 and is in direct contact with both the first nut plate 17 and the second nut plate 19, thus keeping the two nut plates 17, 19 at a defined distance from each other.

[0061] The spacer 29 comprises four coupling extensions 31 that protrude in opposite directions parallel to the central axis Z. Two of which each engage in a recess 33 formed in the first nut plate 17, and the other two each engage in a recess 33 formed in the second nut plate 19. The recesses 33 extend through the respective nut plate 17 or 19, so that they can also be formed in a simple manner by punching. By the engagement of the coupling extensions 31 in the recesses 33, the spacer 29 is secured in a defined position and alignment between the two nut plates 17, 19.

[0062] The spacer 29 is arranged such that, with respect to the central axis Z, it projects radially inward into the receptacle 13 with two contact surfaces 35 aligned perpendicular to one another, each in a direction perpendicular to the respective contact surface 35 (see in particular Fig. 2). As a result, the coupling section of the actuating element must push the contact surfaces 35 radially outward when it is inserted into the receptacle 13. The contact surfaces 35 therefore act on the coupling section inserted into the receptacle 13 radially inward, with the contact surfaces 35 advantageously resting flatly against side surfaces of the coupling section of the actuating element (designed as a square bar). This secures the coupling section of the actuating element in a force-fitting manner in the receptacle 13 and also avoids play between the actuating element and the receptacle 13, which can lead to undesirable cracking noises.

[0063] Furthermore, a coupling lever 37 is pivotably mounted on the coupling section 15 of the gear nut 11 about a pivot axis S parallel to the central axis Z. In the coupling section 15 designed as a bolt, the pivot axis S coincides with the bolt axis, along which the bolt 15 extends and to which it is rotationally symmetrical. The coupling lever 37 extends from a proximal end 39, at which it is connected to the coupling section 15, to a distal end 41, at which it is designed for coupling to the actuating element of the fitting arrangement.

[0064] The coupling lever 37 comprises a first lever plate 43 and a second lever plate 45, which are formed as stamped parts similar to the nut plates 17, 19. The lever plates 43, 45 are mirror-symmetrical to one another and each have a proximal section 47 and a distal section 49, between which a step 51 is formed. The proximal section 47 extends from the proximal end 39 to the step 51, while the distal section 49 extends from the distal end 41 to the step 51. Along their respective proximal section 47, the first lever plate 43 and the second lever plate 45 lie flat against one another, whereas the distal sections 49 are offset parallel to one another due to the steps 51 and are thus spaced apart from one another.

[0065] At the proximal end 39 of the coupling lever 37, the lever plates 43, 45 each have a bore 53, which together form a continuous bore through the coupling lever 37 and through which the coupling section 15, designed as a bolt, extends, whereby the coupling lever 37 is pivotally mounted on the coupling section 15 about the pivot axis S. Between these bores 53 and the bolt 15, a sleeve 55 is arranged, which encloses the bolt 15 (see Fig. 3) and further improves the pivotability.

[0066] The lever plates 43, 45 also each have a bore 53 at the distal end 41 of the coupling lever 37. A further bolt 57 extends through each of these bores 53 with the two end sections of its longitudinal extension and thereby connects the two lever plates 43, 45 to one another at the distal end 41. The further bolt 57 is aligned parallel to the central axis Z. The coupling lever 37 can be drive-effectively coupled to the aforementioned adjusting element of the fitting arrangement, in particular via the further bolt 57. In this way, an adjustment of the gear nut 11, namely a rotation of the gear nut 11 about the central axis Z, can be transmitted via the eccentric bolt 15 to the coupling lever 37 and via the further bolt 57 to the adjusting element of the fitting arrangement.

[0067] The inventive design of the gear nut 11 with two nut plates 17, 19 and the spacer 29 instead of a solid body enables a comparatively simple and cost-effective production of the gear nut 11, without the gear nut 11 having insufficient stability as a result.
