Description

[0001] The invention relates to a panel arrangement for cladding walls with the features of the preamble of claim 1. Furthermore, the invention relates to a method for connecting the panel area to the wall area with the features of claim 12, and to a fastening device with the features of claim 14.

[0002] Stone slabs are typically used as facade cladding for building facades. These are mounted to the exterior wall of a building using fastening systems. Wall anchors, which are glued into the exterior wall, are usually employed for this purpose. If the wall anchors are damaged due to incorrect installation or environmental factors, the corresponding slabs must be additionally secured. For this, a hole is drilled in the slab, a threaded rod is inserted through the hole and fixed in the exterior wall. Finally, a screw is attached to the front of the slab.

[0003] Utility model DE 299 22 513 U1 discloses a fastening element for spacer fastening of a facade panel to a masonry wall, wherein the fastening element is beam-shaped with a larger longitudinal dimension than transverse dimension and has a nut thread on one side, the axis of which passes through the fastening element approximately perpendicular to a longitudinal direction of the fastening element, and on the other side a tension element with which it is pivotably connected.While this system allows the beam-like fastening element to be inserted from the outside of a facade panel through a hole in it, this is only possible because the fixing element, with its longitudinal axis perpendicular to the plane of the facade panel, is not a single piece with a rear fixing section for anchoring in the masonry and a front fixing section that at least partially penetrates the facade panel. Instead, it is a two-part system: a bolt-shaped wall anchor with an internal thread on one side, and a screw that penetrates the facade panel for screwing into the internal thread of the bolt-shaped wall anchor on the other. The screw can only be inserted into the internal thread of the bolt-shaped wall anchor after the beam-like fastening element has been pushed through an opening in the facade panel and aligned.However, it presents considerable difficulties to subsequently screw a screw through the nut thread of the beam-shaped wall anchor and then precisely align it with the internal thread of a bolt-shaped wall anchor located behind it, which is completely hidden in this state, and screw it into that anchor. Since this two-part construction of the fixing device is thus entirely impractical, it is virtually never used in practice. With the predominantly used, one-piece fixing devices, however, a damaged facade panel cannot be replaced using the system known from DE 299 22 513 U1, because the one-piece fixing device then protrudes into the panel opening and makes it impossible to insert the previously known fastening element.

[0004] German patent DE 29 06 794 A1 describes a hollow injection anchor whose shaft can be partially inserted into a borehole in a building and fixed in the borehole by a hardenable filling compound that can be injected into the borehole through a cavity in the anchor shaft. A wall cladding element can be attached to a section of the anchor shaft that protrudes freely from the borehole. In the area of ​​such a wall cladding element, the anchor shaft is surrounded by a sleeve that allows limited movement of the component relative to the anchor shaft. Alternatively, the cavity of the anchor shaft can be penetrated by an axis extending transversely to the longitudinal axis of the shaft, on which a support element is mounted that can pivot out behind the wall cladding element.However, once the dowel shaft is cemented in place, there is no longer any way to change the position of this pivoting support element relative to the building structure in order to subsequently adjust a wall cladding element. Rather, this support element is permanently connected to the dowel shaft and can only be fixed and adjusted together with it.

[0005] German patent application DE 24 18 205 A1 describes a device for fastening facade cladding to a wall, comprising an anchor element and a threaded bolt. The inner end of the threaded bolt, when installed, is aligned with the anchor element, while its outer end features a screw head stop. This device allows for adjustments to be made from the outside, even during the installation of the wall cladding, without requiring access to the area behind the cladding.

[0006] The invention is based on the objective of proposing a fastening device for a panel arrangement that enables support of a panel accessible from one side at its rear. In particular, it should also be possible to replace a damaged facade panel without having to remove the fixing element from the wall area, wherein a rear support element should be adjustable to the thickness of the respective facade panel despite the fixing element being retained during the replacement of the facade panel.

[0007] This problem is solved by a plate arrangement having the features of claim 1, as well as by a method having the features of claim 12 and a fastening device having the features of claim 14.

[0008] Preferred or advantageous embodiments of the invention will become apparent from the dependent claims, the following description and / or the accompanying figures.

[0009] According to the invention, a panel arrangement for cladding walls, comprising a wall area and a panel area, is proposed. The panel arrangement consists in particular of at least one panel, preferably of several hundred panels; more preferably, the panel arrangement forms a complete building facade. The wall area is in particular a building wall, preferably an exterior wall or an interior wall; more preferably, the interior wall is an interior wall and / or a ceiling and / or a floor.

Specifically, the distance is at least 3 cm, preferably more than 10 cm, particularly preferably more than 20 cm, and especially more than 30 cm. Alternatively or optionally, the distance is particularly less than 50 cm, preferably less than 25 cm, particularly preferably less than 15 cm, and especially less than 5 cm.

[0011] Furthermore, the fastening device includes a fixing element. The fixing element is, in particular, designed as a threaded rod, a stud bolt, or a drive-in anchor.

[0012] Preferably, the fixing element is made of a corrosion-resistant material, e.g., stainless steel, or comprises a corrosion-resistant alloy, e.g., a zinc alloy. The fixing element defines a principal axis; preferably, the fixing element defines the principal axis with its central axis or axis of symmetry.

[0013] The fixing device comprises a first fixing section and a second fixing section, the first fixing section being connected to the wall area. For this purpose, the wall area is provided, for example, with a borehole, so that the first fixing section can then be inserted into the borehole. In particular, the first fixing section is connected directly via positive locking or by means of a material-bonded compound, such as...

[0014] The material is connected to the wall area using synthetic resin mortar, bonding mortar, or bonding adhesive, or by means of a dowel, such as a cavity anchor or heavy-duty anchor. For example, the first fixing element is a metric thread, a wood screw thread, a dowel thread, or an expansion sleeve.

[0015] The second fixing section extends at least partially through the plate opening. In particular, an axial end or a partial section of the second fixing section extends completely or partially through the plate opening. Preferably, the central axis of the plate opening and the principal axis of the fixing means form a common axis, so that the fixing means, in particular the second fixing section, extends centrally through the plate opening. The second fixing section is particularly preferably arranged coaxially and / or concentrically to the plate opening. The second fixing section has, in particular, a diameter or thickness that is smaller than the diameter or width of the plate opening.

[0016] In particular, the difference is more than 0.5 cm, preferably more than 1.5 cm, particularly preferably more than 3 cm, and specifically more than 5 cm. In particular, the difference is less than 10 cm, preferably less than 6 cm, particularly preferably less than 4 cm, and specifically less than 1 cm.

[0017] The invention proposes that the fastening device includes a tilting element, which can be arranged on the fixing section. In particular, the tilting element is a separate component in its uninstalled state and, in its installed state, forms the fastening device or part thereof together with the fixing means. For this purpose, the fixing means is connected to the wall area, particularly in a first step, and the tilting element is arranged on the fixing means, preferably the second fixing section, in a further step. The tilting element is, for example, a sheet metal part, preferably made of a corrosion-resistant material such as aluminum or a corrosion-resistant alloy. Alternatively, the tilting element is made of plastic or a composite material.

[0018] The tilting element has a support surface for bracing against the plate area. Specifically, the support surface, viewed from a top view, is a top surface or a partial top surface of the tilting element. The support surface defines a support plane. In particular, the support surface is a planar surface, where all points on the surface are coplanar and thus define the plane. Alternatively or optionally, the support surface may have a profile, e.g., teeth, or a coating, e.g., a rubber coating.

[0019] In an insertion position, the tilting element forms a first angle (alpha 1) with its support plane and the main axis, or is arranged parallel to the main axis. In particular, in the insertion position, the tilting element is inserted into the plate opening parallel to the main axis or tilted slightly so that the first angle is formed, and then tilted in the direction of the main axis or further tilted in the direction of the main axis.

[0020] In its end position, the tilting element forms a second angle (alpha 2) with its support plane and the main axis, or is arranged perpendicular to the main axis. In the end position, the tilting element is preferably in a mounted position. The transition from the insertion position to the end position is preferably achieved by tilting the tilting element, with the first angle preferably increasing continuously during the transition until the end position and / or the second angle is reached. In particular, the tilting element is displaced axially along the main axis towards the wall area and / or towards the panel area during the transition, so that the angle of the tilting element with respect to the main axis preferably changes during the transition depending on the axial position of the tilting element.

[0021] In its end position, the support surface of the tilting element supports the tilting element at least partially against the plate area. In particular, the support surface supports the tilting element against the plate area at at least one point, preferably at least two points. More preferably, the plate area defines a second plane such that, in the end position, the support plane of the tilting element is parallel to the second plane. In particular, the support surface forms a positive-locking and / or force-locking connection with the plate area in the end position. The support surface contacts the plate area indirectly, for example via a shim such as a washer or rubber mat, or directly. Alternatively, the support surface consists of a first and a second support surface, wherein the first and second support surfaces are arranged opposite each other, preferably spaced apart.

[0022] The first angle is smaller than the second angle. In particular, the first angle is greater than 5°, preferably greater than 20°, particularly preferably greater than 40°, and specifically greater than 60°. In particular, the first angle is less than 70°, preferably less than 50°, particularly preferably less than 30°, and specifically less than 15°. The second angle is greater than 45°, preferably greater than 65°, particularly preferably greater than 85°, and specifically greater than 90°. In particular, the second angle is less than 100°, preferably less than 90°, particularly preferably less than 75°, and specifically less than 55°.

[0023] Particularly preferably, the second angle is exactly 90°. The difference between the first angle and the second angle is preferably greater than 30°, particularly greater than 45°, and especially greater than 60°.

[0024] The tilting element according to the invention provides additional support to the panel area at its rear, thus reducing any oscillation of the panel towards the wall area. A further advantage is that the panel area is adjustable axially to the main axis. This allows the distance between the panel area and the wall area to be varied by adjusting the tilting element axially to the main axis. By adjusting the panel area, for example when replacing a damaged panel or during initial installation, the panel area can be aligned with adjacent panel areas axially to the main axis, thus ensuring a uniform distance from the wall.A particular advantage of the tilting element according to the invention is that the tilting element can be retrofitted to an already mounted plate, which is only accessible from one side and thus the plate can be supported at its rear.

[0025] To accommodate the second fixing section, the tilting element has an insertion opening. This insertion opening is designed to guide the tilting element axially along the main axis of the second fixing section. The insertion opening extends further along a longitudinal axis of the tilting element than along its transverse axis, allowing the tilting element to be moved from the insertion position to the end position. In particular, the insertion opening has an elongated, rectangular, or oval shape. For example, the axial extent of the insertion opening along the longitudinal axis and / or along the transverse axis is no more than 95%, particularly no more than 80%, and preferably no more than 65% of the axial extent of the tilting element along the longitudinal axis and / or along the transverse axis.Preferably, the axial extent of the insertion opening along the transverse axis is only slightly larger than the diameter of the second fixing section, so that the tilting element can be easily displaced on the second fixing section. In particular, the difference between the diameter of the second fixing section and the axial extent of the insertion opening along the transverse axis is more than 0.1 mm, preferably more than 1 mm, and particularly preferably more than 10 mm. In particular, the difference is less than 20 mm, preferably less than 5 mm, and particularly preferably less than 1 mm, specifically less than 0.1 mm. Preferably, the insertion opening is arranged concentrically to the tilting element. Alternatively, the insertion opening is arranged eccentrically to the tilting element.

[0026] In a preferred embodiment of the invention, the fastening device comprises a fastening element, wherein the fastening element can be arranged between the wall area and the tilting element. The fastening element is preferably a nut, e.g., a hexagonal nut or a square nut. Particularly preferred is a self-locking nut. Specifically, the fastening element is made of a corrosion-resistant material, e.g., stainless steel, or a corrosion-resistant alloy, e.g., a zinc alloy. In particular, the fastening element is arranged coaxially and / or concentrically with respect to the fixing element.

[0027] The tilting element has a mounting surface so that it is axially supported by the fastener. In particular, the mounting surface, viewed from below, is a bottom surface or a partial bottom surface of the tilting element. Specifically, the mounting surface, preferably in an end position, contacts the fastener indirectly, for example via a shim or clamping element, e.g., a washer, or directly. Alternatively, the mounting surface consists of a first and a second mounting surface.

[0028] In a further preferred embodiment, the fastening element has an internal thread, and the first and / or the second fixing section has an external thread. The internal and external threads are, in particular, metric threads. Preferably, the internal thread engages with the external thread, and the fastening element is particularly preferably movable in the axial direction by rotation about the main axis. In particular, in a second step, after the fixing element has been set, the fastening element is screwed onto the fixing element. In particular, by rotating the fastening element in the direction of rotation, preferably clockwise, the fastening element is positioned axially along the main axis towards the wall area. In a third step, the tilting element is tilted, in particular towards the fastening element, so that the tilting element assumes a mounting position.The mounting position is preferably the positioning of the tilting element on the fixing section, with the tilting element forming the second angle with the main axis and the support surface of the tilting element not in contact with the plate area. In a fourth step, the fastening device is moved axially along the main axis towards the plate area, preferably by rotation in the direction of rotation, to clamp the tilting element against the plate area. Particularly preferably, the tilting element is moved from the mounting position to the final position by rotation in the direction of rotation.

[0029] In a constructive implementation, the tilting element defines a longitudinal axis and a transverse axis, with the tilting element extending further along the longitudinal axis than along the transverse axis. In particular, the tilting element has an elongated, rectangular, or oval shape. Preferably, the axial ends along the longitudinal axis are rounded, angular, and / or acute-angled in the top and / or bottom view. Particularly preferably, the tilting element, especially when viewed from the front and / or rear, has an insertion section at its axial ends along the longitudinal axis. For example, the insertion section is designed as a radius or a chamfer.

[0030] In a preferred design embodiment, the tilting element has a contact section. In particular, the contact section extends parallel to or lies on the transverse axis. Preferably, the contact section is a web formed by a clamping element or is materially bonded to the tilting element, or it is a wall section of the tilting element. Particularly preferably, the contact section has a recess, e.g., a groove, a notch, or a radius. Specifically, the recess forms a contour partner with the second fixing section in the insertion position and / or in the assembly position and / or in the end position.

[0031] The support section supports the tilting element in the assembly position and / or the end position on the second fixing section. In particular, the support section limits the tilting element axially along its longitudinal axis. Preferably, the support section is arranged on the longitudinal axis of the tilting element such that the geometric center of the tilting element lies on the main axis in the end position and / or the assembly position.

[0032] In an alternative embodiment, the tilting element comprises a spirally wound metal strip as its base body. The base body has, in particular, at least one turn, such that the metal strip forms a closed ring. More specifically, the base body has at least one second turn; preferably, the base body has more than three turns; and most preferably, the base body has exactly three turns. In particular, the metal strip, by its winding shape, defines the contour of the tilting element and / or the insertion opening.

[0033] In a further alternative embodiment, a section of the metal strip is bent at least once. This section is, in particular, an axial end of the metal strip or an intermediate section of the metal strip. The section is bent, in particular, by more than 15°, preferably by more than 30°, particularly preferably by more than 45°, and specifically by more than 85°. In particular, the section is bent by less than 100°, preferably by less than 75°, particularly preferably by less than 50°, and specifically by less than 25°. It is particularly preferred that the section is bent by exactly 90°. In particular, the section is bent twice, and preferably by three times.

[0034] The subsection forms the mounting section and / or a web section. The web section extends, in particular, parallel to the mounting section or to the transverse axis of the tilting element. In particular, the subsection, preferably the mounting section and / or the web section, extends over at least half the width of the tilting element, and most preferably over the entire width of the insertion opening.

[0035] In a further preferred embodiment, the tilting element has an off-center center of gravity, such that the tilting element is supported by the support section during rotation in the direction of rotation with respect to the main axis. For example, the off-center center of gravity lies on the longitudinal axis. In particular, the off-center center of gravity is an off-center geometric center of gravity or an off-center center of mass. For example, the off-center center of gravity is formed by attaching an additional weight, e.g., a lead weight, to an axial end of the tilting element and / or by the off-center arrangement of the support section. In particular, the support section is arranged off-center with respect to the longitudinal axis. The rotation of the tilting element in the direction of rotation with respect to the main axis is in particular more than 90°, preferably more than 120°, and most preferably more than 160°.

[0036] The off-center center of gravity positions the tilting element in a stable or metastable position. In particular, in an initial position, the contact section is radially further from the main axis than in the final position and / or the mounting position. Rotation of the tilting element in the direction of rotation preferably results in a displacement of the tilting element within the insertion opening. Specifically, during a rotation greater than 90° and less than 270°, the off-center center of gravity positions the tilting element in a stable or metastable position. Most preferably, during rotation within the aforementioned range, the tilting element assumes a vertical position due to the off-center center of gravity, with the contact section resting radially on the fixing section.

[0037] In another alternative embodiment, the plate arrangement includes a tool device for clamping the tilting element to the plate area via the fastener. In particular, the tool device sets the fastener in a rotational movement, so that the fastener, and thus the tilting element, is moved from the mounting position to the final position.

[0038] The tool device has a receiving section, which is designed to receive the screw and / or the tilting element and / or the web section. The tool device is particularly designed as a type of socket wrench, with the receiving section preferably having at least one contact surface, which is particularly preferably positively and / or frictionally engaged with an outer surface of the fastener and / or the mounting section. In particular, the tool device has a further receiving section, which is designed to receive the second fixing section. For example, the further receiving section is designed as a tube, so that the tool device can be slid onto the second fixing section and is thus centered.

[0039] The tilting element is fixed by the receiving section and / or the fastening means during a rotational movement of the tool fixture in the radial and / or axial and / or circumferential direction. In particular, the receiving section of the tool fixture is designed such that it can be inserted into the insertion opening, preferably with a precise fit or with minimal clearance. The tool fixture or the receiving section is thus restricted in the circumferential direction relative to the main axis by the insertion opening, so that the tool fixture carries the tilting element along in the circumferential direction. Alternatively or optionally, the receiving section may additionally encompass the tilting element on its outer surface.

[0040] In particular, the receiving section has at least one, preferably two, wing sections, wherein the wing sections are particularly preferably arranged parallel and spaced apart from each other. In particular, the wing sections encompass the fastening means and / or the tilting element on at least one side. Preferably, the wing sections encompass both the fastening means and the wing section. Thus, the tilting element is particularly preferably limited radially in the direction of the main axis by the second fixing section in the mounting position and / or the end position, and limited radially away from the main axis by the wing section. The tilting element is particularly limited axially in the direction of the wall area by the fastening means and axially in the direction of the panel area by the receiving section, in particular by the wing section, in the mounting position and / or the end position.

[0041] In a further preferred embodiment, the fastening device comprises a first and a second transmission element for transferring a weight force from the plate area to the fixing section. The transmission elements are preferably formed as a single sheet metal part. The first transmission element has a first guide opening and the second transmission element has a second guide opening, the guide openings being designed to receive the fixing section. The guide openings are formed, in particular, by a cutting process, for example, drilling, milling, or punching. At least one guide opening is formed by an elongated hole, so that the transmission elements are displaceable relative to each other.In particular, the guide opening of the first and / or the second guide opening is a bore, so that the first and / or the second transmission element can preferably be slid axially onto the second fixing section without play or with a small amount of play; particularly preferably the first and / or the second guide opening is the elongated hole, so that the first and / or the second transmission element can be displaced in the axial and radial direction on the main axis.

[0042] The first and second transmission elements each have a profile on at least one of their surfaces, such that when the two transmission elements are clamped axially to the main axis, they are connected to each other by force-fit, positive-fit, and / or friction-fit via the profile. In particular, the profile is a toothed joint, preferably formed by webs, teeth, or grooves. The transmission elements are arranged in the area of ​​the opening, preferably with at least one of the two transmission elements contacting the plate area. The clamping of the two transmission elements is achieved by a further fastening means, such that the transmission elements are clamped axially in the direction of the tilting element, thus preventing and / or stopping any relative displacement of the two transmission elements relative to each other.

[0043] Alternatively or optionally, the plate opening has a recess, the recess extending fully or partially in the axial direction, particularly parallel to the main axis. Preferably, the recess is a groove, e.g., a keyway or a notch. In particular, the second transmission element, with its side contacting the plate area, preferably the recess, forms a positive-locking connection with the recess. Alternatively or optionally, the second transmission element has a lug, the lug forming a positive-locking connection with the recess. For example, the lug has a round, angular, oval, or acute-angled shape. Particularly preferably, the second transmission element is fixed by the recess in the direction of rotation relative to the main axis, thus preventing rotation of the second transmission element in the direction of rotation.

[0044] Another object of the invention is a method for fixing a panel in front of a wall and a method for connecting a panel area to a wall area as described above or according to one of the preceding claims.

[0045] Another object of the invention is a fastening device for connecting a panel area with a wall area, preferably for forming a panel arrangement as previously described or according to one of the preceding claims.

[0047] Corresponding or identical parts are each provided with the same reference symbols in the figures.

[0048] The Fig. Figure 1 shows a longitudinal section along a principal axis H of a plate arrangement 1 with a fastening device 5. The plate arrangement 1 has a wall area 2, e.g., the exterior wall of a building, and a plate area 3, e.g., a natural stone slab, wherein the plate area 3 is connected and / or connectable to the wall area 2 via the fastening device 5. The plate area 3 has a plate opening 4, e.g., a circular opening. The plate opening 4 extends completely through the plate area 3 axially along the principal axis H.

[0049] The fastening device 5 comprises a fixing element 6, the central axis of which defines the principal axis H. The fixing element 6 has a first fixing section 6a and a second fixing section 6b. The first fixing section 6a is connected to the wall region 2, and the second fixing section 6b is connected to the plate region 3. For example, the fixing element 6 is a threaded rod, with the first fixing section 6a being fixed, e.g., in a bore, in the wall region 2, e.g., by gluing. The second fixing section 6b extends through the plate opening 4 and has an end piece 13 and an expansion element 14 at one axial end. The end piece 13 supports the plate region 3 axially along the principal axis H. The expansion element 14 is arranged between the plate region 3 and the end piece 13 and serves to compensate for thermal expansion of the plate region 3.For example, end piece 13 is a point holder and expansion element 14 is a rubber insert.

[0050] Furthermore, the fastening device 5 has a tilting element 7, which is arranged on the second fixing section 6b. The tilting element 7 has a support surface 8 and a mounting surface 9. In an end position of the tilting element 7, the support surface 8 axially supports the panel area 3 along the principal axis H in the direction of the wall area 2. The tilting element 7 defines a longitudinal axis L, which, in the end position, forms a second angle α2 with the principal axis H. For example, the second angle α2 is a right angle.

[0051] The fastening device 5 has a fastening element 10, the fastening element 10 being arranged coaxially on the second fixing section 6b. The fastening element 10 can be positioned axially along the main axis H on the second fixing section 6b. In its end position, the tilting element 7 is supported axially in the direction of the wall area 2 by the fastening element 10, with the tilting element 7 bearing against the fastening element 10 with its fixing surface 9 in the end position.

[0052] Furthermore, the fastening device 5 comprises a first and a second transmission element 15a, b. The first and second transmission elements 15a, b can be arranged on the second fixing section 6b and are axially displaceable along the main axis H. The first transmission element 15a is fixed in the radial direction to the main axis H. The second transmission element 15b is displaceable in the radial direction to the main axis H. The plate section 3 has a recess 30, wherein the recess 30 is, for example, a groove. The recess 30 extends, in particular within the plate opening 4, parallel to the main axis H over the entire length of the plate opening 4. The second transmission element 15b contacts the plate section 3 in the region of the recess 30, so that a weight force of the plate section 3 is transmitted via the second transmission element 15b to the first transmission element 15a, to the fixing means 6, and subsequently to the wall section 2.The second transmission element 15b is fixed by the recess 30 in the direction of rotation to the main axis H, so that a rotation of the second transmission element 15b in the direction of rotation to the main axis H is prevented.

[0053] The fastening device 5 has at least one further fastening element 11 and / or a shim 12. The further fastening element 11 and / or the shim 12 can be arranged, for example, for further fixing to the wall area 2 and / or to the tilting element 7 and / or to the first transmission element 15a and / or to the second transmission element 15b.

[0054] The Fig. Figure 2 shows a longitudinal section along the main axis H of the plate arrangement 1 with the fixing means 6 and the tilting element 7 in various positions. In the first position I, the tilting element 7 is in an insertion position. The longitudinal axis L is parallel to the main axis H, so that the tilting element 6 can be inserted into the plate opening 4. During the insertion process, the tilting element 7 is displaced axially along the main axis H and simultaneously tilted in the direction of the main axis H, so that in a second position II, the tilting element 7 forms a first angle α1 with the main axis H with its longitudinal axis L. Furthermore, the tilting element 7 has at least one insertion section 29 at at least one axial end with respect to the longitudinal axis L.The introduction section 29 extends from the top of the tilting element 7 towards the bottom of the tilting element 7, in particular the introduction section 29 extends from the support surface 8 towards the support surface 9. For example, the introduction section 29, particularly in a front view, is designed as a radius and / or a chamfer and / or a chamfer.

[0055] In a third position III, the tilting element 7 forms the second angle alpha 2 with the principal axis H, with the tilting element being in an assembly position or in an end position. The first angle alpha 1 is smaller than the second angle alpha 2 throughout the entire insertion process. For example, the first angle alpha 1 is between 0° and 70° during the insertion process, and the second angle alpha 2 in the end position and / or assembly position is at least and / or exactly 90°.

[0056] Fig. Figure 3 shows the tilting element 7 in a disassembled state, the tilting element 7 defining a transverse axis Q and a longitudinal axis L. The tilting element 7 is oval-shaped, extending further along the longitudinal axis L than along the transverse axis Q. The tilting element 7 has a base body 20 and an insertion opening 16 for receiving the fixing means 6. The base body 20 is formed by a metal strip 21, which is wound spirally. The insertion opening 16 is formed by the metal strip 21, and depending on the number and / or winding type, the insertion opening 16 and / or the base body 20 can be shaped as desired. The tilting element 7 has a web section 18. The web section 18 is formed by an axial end of the metal strip 21, which is angled. For example, the metal strip 21 is angled at 90°.The web section 18 rests with its open end against the base body 20, so that the web section 18 stabilizes the base body 20.

[0057] Furthermore, the tilting element 7 has a clamping element 19. The clamping element 19 is attached to the base body 20, for example, after the metal strip 21 has been wound, so that at least one axial end is fixed and unwinding of the metal strip 21 is prevented. The clamping element 19 forms the mounting surface 9 with its underside. Alternatively, the tilting element 7, in particular the base body 20, forms the mounting surface 9 with its underside. The clamping element 19 forms a contact section 17, wherein the contact section 17 supports the tilting element 7 radially in the direction of the main axis H on the fixing element 6. For example, the contact section 17 has a recess which forms a contour partner with the fixing element 6, in particular with the second fixing section 6b.Alternatively or optionally, the system section 17 is bent on its underside towards the top of the tilting element 7, in particular the system section 17 runs in a bridge-like manner from one side of the base body 20 into the insertion opening 16 to an opposite side of the base body 20.

[0058] According to the Fig. Figure 4a shows the tilting element 7 in an initial position. In the Fig. Figure 4a shows a front view of the tilting element 7 with the fixing means 6, where the mounting section 17 is arranged off-center. The longitudinal axis L and the transverse axis Q form a center point M at their common intersection. The center point M is, for example, the geometric center, e.g., of the outer contour, of the tilting element 7. In the initial position, the center point M is spaced apart from the principal axis H. The principal axis H forms a pivot point, whereby the tilting element 7 can be rotated about the principal axis H or the pivot point. The base body 20 of the tilting element 7 has a first base body section 20a and a second base body section 20b. The first base body section 20a and the second base body section 20b are separated by the mounting section 17. An off-center center of gravity lies within the first base body section 20a.In the initial position, the tilting element 7 rests partially with an axial end on the fixing means 6 in relation to the longitudinal axis L of the first base body section 20a radially to the main axis H.

[0059] Fig. Figure 4b shows the tilting element 7 in a rotational position. To move the tilting element 7 from its initial position to its assembly position and / or final position, it is rotated in a direction D around the main axis H. Beyond a certain angle of rotation, the center point M shifts towards the main axis H due to gravity and / or the off-center center of gravity. The tilting element 7 shifts within the first base section 20a in the direction of the system section 17.

[0060] During the Fig. In the illustration shown in Figure 4c, the tilting element 7 is in its end position or assembly position. For example, the tilting element 7 is rotated 180° around its main axis of rotation relative to its initial position. Due to the arrangement of its off-center center of gravity in the first base body section 20a, the tilting element 7 is in a stable and / or metastable position in its assembly and / or end position. In its end or assembly position, the tilting element 7 rests on the fixing means 6, such that the tilting element 7 is radially limited in the direction of the main axis H by the support section 17. For example, the support section 17 is arranged such that the center point M of the tilting element 7 lies on the main axis H.

[0061] Fig. Figure 5 shows a tool device 22 for transferring the tilting element 7 from the assembly position to the end position. The tool device has a receiving section 23. The receiving section 23 is designed to receive the fastening element 10 and / or the mounting section 17. The mounting section 23 has at least one wing section 25, wherein the wing section 25 has at least one contact surface 26. Furthermore, the tool device 22 has a further receiving section 24, e.g., the further receiving section 24 is tubular. The further receiving section 24 can be slid onto the second fixing section 6b.

[0062] Fig. Figure 6 shows the transfer of the tilting element 7 from the mounting position to the final position using the tool device 22. The illustration shows the final position of the tilting element 7 and indicates the mounting position. To transfer it from the mounting position to the final position, the tool device 22 is pushed onto the second fixing section 6b until the wing section 25 engages the fastener 10 on both sides and / or the contact section 17 makes contact with the wing section 25. By rotating the tool device 22 in the direction of rotation about the main axis H, the fastener 10, and thus the tilting element 7, is moved axially along the main axis H. The tool device 22 is rotated in the direction of rotation until the tilting element 7, with its 8, makes contact with the plate area 3 or is supported by the plate area 3.

[0063] Fig. Figure 7 shows a cross-sectional view through the wing section 25 of the tilting element 7 with the fastening element 10 and the fixing section 6 in the end position or the mounting position. The tilting element 7 rests with its contact section 17 on the fixing element 6, so that the tilting element 7 is limited radially to the main axis H. The wing section 25 is arranged within the insertion opening 16 and extends over the entire width of the insertion opening 16, so that the tilting element 7 is limited in the direction of rotation with respect to the main axis H. The contact surface 26 of the wing section 25 surrounds the fastening element 10 on both sides, so that the fastening element 10 is carried along when the tool device 22 is rotated in the direction of rotation with respect to the main axis H.The contact surface 26 of the wing section 25 limits the mounting section 17 in the radial direction to the main axis of rotation H, so that the tilting element 7 is limited radially away from the main axis of rotation H. As in . Fig. As shown in Figure 6, the tilting element 7 is axially restricted in the direction of the wall area 2 by the fastening means 10 and / or axially restricted in the direction of the plate area 3 by the tool device 22, in particular by the receiving section 23, preferably by the wing section 25, and most preferably by the contact surface 26. Thus, the tilting element 7 is completely fixed when being moved from the mounting position to the end position or from the end position to the mounting position.

[0064] Fig. Figure 8a shows the first transmission element 15a, wherein the first transmission element 15a has a first guide opening 27a for receiving the fixing means 6, in particular the second fixing section 6b. For example, the first transmission element 15a has a square, circular, oval, oblong, or rectangular shape. The first guide opening 27a is a bore, e.g., the bore has a diameter dimensioned such that the second fixing section 6b can be received with minimal play. For example, the guide opening 27a has an internal thread so that the first transmission element 15a can be screwed onto the second fixing section 6b.

[0065] Fig. Figure 8b shows the second transmission element 15b, wherein the second transmission element 15b has a second guide opening 27b for receiving the fixing means 6, in particular the second fixing section 6b. For example, the second transmission element 15a has a rectangular, oval, or elongated shape. The second transmission element 15b is in an installed state, as shown in Fig. As already described in section 1, the second guide opening 27b is attached to the plate area 3, so that a weight force of the plate area 3 can be transferred to the first transmission element 15a and thus to the fixing element 6. The second guide opening 27b is an elongated hole; for example, the elongated hole has a width dimensioned such that the second fixing section 6b can be received with minimal play. The second transmission element 15b is radially displaceable through the second guide opening 27b relative to the main axis H. Due to the radial displacement of the second transmission element 15b, the second transmission element 15b is displaceable relative to the first transmission element 15a.

[0066] According to the Fig. 8a and Fig.8b The first and second transmission elements 6a, b have a profile 28. The profile 28 is formed by a recess in at least one surface of the first and second transmission elements 6a, b. For example, the profile 28 is formed by webs and / or grooves and / or teeth and / or notches. When the two transmission elements 6a, b are installed, the profile 28 of the first transmission element 6a engages with the profile 28 of the second transmission element 6b, thus preventing relative displacement of the two transmission elements 6a, b. For example, the two transmission elements 6a, b are clamped together by at least one further shim 12 and / or at least one further fastener 11. Reference symbol list 1.
