Description

[0001] The invention relates to a fastening arrangement between a holder and a cable support component, in particular between two components of a cable support system. Furthermore, the invention relates to a holder for such a fastening arrangement with a connection adapter molded thereto.

[0002] Such fastening assemblies are used, for example, when installing or assembling components of a cable support system to fasten two cable support components together. In such a case, the holder for such a fastening assembly is, for example, a headpiece or head plate, to which a suspended support is attached as a cable support component. The head plate or headpiece is fixed to the underside of a ceiling. A suspended support is attached to this support, to which other cable support components are or will be attached, such as brackets for supporting a cable tray or cable duct.

[0003] EP 0 712 191 A1 discloses a fastening arrangement in which a first profile piece is attached to the ceiling. A second profile piece is connected to this profile piece. This second profile piece is designed as a hollow chamber profile and dimensioned such that a suspended support can be inserted into its cavity. The suspended support piece is connected to the second profile piece by means of screw connectors.

[0004] Another fastening arrangement is known from WO 2021 / 254921 A2. This fastening arrangement has a head plate with a receptacle enclosed by two side walls for inserting a hanging pole. The hanging pole, inserted into the receptacle, is attached to the head plate using screw fasteners.

[0005] Such a fastening arrangement with a head piece and a hanging post is known, for example, from EP 4 131 682 A1. In this fastening arrangement, the head piece is a stamped and bent part with a U-shaped cross-section, the opposing side cheeks of which enclose a post receptacle for inserting the upper section of a hanging post. Retaining tabs project inward from the side cheeks at a vertical distance corresponding to the spacing of the hole pattern of a hanging post. By exploiting the possibility of elastic adjustment of the side cheeks, the post receptacle can be widened by pushing in the end cut of the hanging post, so that the retaining tabs each engage in an opening in the hole pattern. The hanging post is then suspended from the retaining tabs of the head piece.Additional guide tabs, which protrude inwards from the side walls, serve to guide the end section of a hanging pole to be inserted, so that the inwardly protruding retaining tabs are aligned with the hole pattern of the hanging pole in the direction of insertion of the hanging pole.

[0006] Another fastening arrangement of this type is known from EP 1 589 626 A1. The head piece of this previously known fastening arrangement is also a stamped and bent part, which, in contrast to the fastening device known from EP 4 131 682 A1, provides a circumferentially closed receptacle for the suspended support. In this fastening arrangement, inwardly flared retaining tabs are located only on one side wall. A similar design to that disclosed in EP 1 589 626 A1 is also described in EP 0 732 788 A1. In this previously known fastening arrangement, too, an outwardly angled section is provided on the top of each side wall of the suspended support for fastening the suspended support to the ceiling.

[0007] EP 1 471 616 A1 discloses a suspended support constructed as an at least largely closed profile, manufactured as a stamped and bent part. Two opposing side walls carry outwardly bent fastening tabs on the top side with fastener openings for connecting the suspended support to a ceiling.

[0008] With this fastening arrangement, the hanging post hangs from the inwardly flared retaining tabs of the head piece. The respective post receptacle of the head piece thus forms a negative structure to accommodate the upper end of the hanging post. The front end of the hanging post, which is inserted into the head piece, is spaced from the underside of the head piece's fastening plate. Even if such a fastening arrangement is sufficient for many load cases, it does not always meet the higher load-bearing demands placed on such a fastening arrangement. A problem with the subject matter of EP 1 589 626 A1 is that the fastening arrangement between the head piece and the hanging post cannot be released, at least not without first loosening the holder on the ceiling side, in order to then engage the head piece's receptacle from above in order to press the retaining tabs out of the openings. This is sometimes desired.

[0009] Another fastening arrangement of the above type is known from WO 2018 / 109420 A1. In this fastening arrangement, an additional locking element is inserted into the head piece, which has a U-shaped cross-section. This locking element can be moved relative to the side cheeks of the head piece at a certain inclination to the insertion direction of a hanging post. When a hanging post is inserted between the side cheeks, the locking element, which has flared retaining tabs on its side facing the hanging post, is moved slightly laterally away from the hanging post so that the retaining tabs can be moved past the outside of the end section of the hanging post. If the end section of the hanging post is pushed sufficiently far into the post receptacle of the head piece and the retaining tabs are aligned with the openings of the perforated catch of the hanging post, the locking element engages in these openings.The greater the weight on the suspended support, the more secure the locking mechanism between the locking element and thus the headpiece and the suspended support. However, when the suspended support is unloaded, it may be inadvertently shifted toward the headpiece during the installation of additional cable support components to the suspended support, or even independently of this, resulting in the suspension support's intended locking mechanism to the headpiece being removed or at least impaired.

[0010] Based on the prior art described above, the object of the invention is therefore to propose a fastening arrangement as mentioned at the outset, with which the disadvantages mentioned above with regard to the prior art assessed are overcome.

[0011] This object is achieved according to the invention by a fastening arrangement with a holder with a connected, protruding connection adapter designed as a positive structure and with a cable support component profiled at least in one connection section to form an adapter receptacle designed as a negative structure and engaged with the connection adapter, wherein the adapter receptacle is enclosed by a front wall having at least one opening as a locking latch, two side walls formed thereon and a support abutment formed on at least one side wall and opposite the front wall, and wherein the connection adapter has as a profile a front wall, two side walls and at least one support element opposite the front wall, supported on the support abutment of the adapter receptacle and has a locking member,which passes through the front wall of the connection adapter and engages with a latch into the latch catch of the adapter receptacle, which latch member is adjustable against the restoring force of at least one spring element to engage its latch with the latch catch of the adapter receptacle.

[0012] This fastening arrangement is, as far as known, the first implementation of a concept in which the holder comprises a connection adapter designed as a positive structure. Accordingly, the cable support component to be connected to the holder has a connection section formed by a corresponding profile with an adapter receptacle, which engages with the holder-side connection adapter to create the fastening arrangement. An advantage of such a design of the fastening arrangement is that, for locking the connection adapter to the cable support component, the connection adapter can have a locking element whose lock engages or passes through a corresponding opening in the connection section of the cable support component, serving as a locking latch, and is nevertheless accessible from the outside. The latch can thus be easily pushed out of the locking latch, thus releasing the fastening arrangement.The connection adapter of this fastening arrangement therefore has such a locking element, which can be adjusted in the radial direction against the restoring force of at least one spring element. The provision of an independent locking element with a bolt engaging in a latch of the cable support component connected to the connection adapter or to be connected to it has the advantage that this can be designed accordingly with regard to the load to be absorbed, regardless of the material selection and the material dimensions of the hanging post and also of the other components of the connection adapter or the holder. Such a locking element can, for example, be a bolt, the diameter of which corresponds to a multiple of the material thickness of the connection adapter, which is typically designed as a stamped and bent part. A typical material thickness for the connection adapter designed as a profile piece is between 2 and 3 mm. The diameter of the bolt orIn contrast, the diameter of its locking element can be 12 mm or more. Typically, the diameter of the locking element's locking bar corresponds to the clear width of the holes in the hole pattern of the connection section of a cable support component that is to be connected to the connection adapter. Accordingly, even when using only a single locking element, the loads that can be absorbed by the connection adapter connected to the holder are high. The provision of the connection adapter as a positive structure is used in this fastening arrangement to design it with several walls, typically as a polygonal profile, that enclose an adapter chamber. This not only improves rigidity, particularly with regard to torsional stresses acting on it, but also creates a chamber into which the locking element can be adjusted and in which the spring element(s) acting on the locking element are arranged.The connection adapter comprises a front wall, two side walls molded onto the sides, and a back opposite the front wall. In an embodiment intended for higher loads, the back connects the two side walls on their side opposite the front wall. However, it is also possible to design the back as a back part that is bent on at least one side wall on the side opposite the front wall. If two such back parts are provided, i.e., a bent back part is molded onto each side, the back parts do not need to touch each other at their joints.

[0013] The provision of a connection adapter designed as a positive structure further has the advantage that the back opposite the latch with respect to the longitudinal axis of the connection adapter can be supported as a support element on an inner wall or an inner wall part of the adapter receptacle of the connection section of the cable support component. This is implemented accordingly in a preferred embodiment. This support takes place on an inner wall section, specifically one that lies opposite the front wall and thus the latch. If the latch of the locking member engages in the latch catch of the connection section of the cable support component or passes through it, which is the case in a preferred embodiment, the cable support component is suspended on one side from the connection adapter.The resulting tilting moment is absorbed by the support arrangement described above and transferred to the support abutment opposite the front wall of the connection adapter, thus providing a particularly secure, durable, and highly resilient connection. This results from the fact that the weight force introduced into the connection adapter is transmitted not only via the locking element but also via its support element, thus cleverly providing two-sided suspension for the cable support component.

[0014] By providing at least one spring element acting on the locking member, against which the locking member is adjustable, the restoring force can be adjusted to meet the requirements, regardless of the material properties of the connection adapter. In particular, the provision of a spring element allows the application of an elastic restoring force over a greater range of movement of the locking member, as does the provision of one or more spring elements, which can also provide higher forces acting on the locking member. This is useful for providing a secure fastening arrangement, especially when used in a vibration-prone environment.

[0015] The connection section of the cable support component to be connected to the connection adapter is designed as a negative structure complementary to the connection adapter. This negative structure is provided by a front wall, two side walls formed laterally thereon, and a support abutment located opposite at least one side wall of the front wall. In this respect, the adapter receptacle can be designed with a C-shaped cross-section, wherein in a preferred embodiment the side walls additionally have a folded back directed towards the front wall. Likewise, it is possible for the connection section of the cable support component to be a closed profile. In many cases, the profiling of the cable support component will not be limited to the connection section. Rather, this profiling will extend over the entire length of the cable support component.The required cable support component piece can then be easily cut from a longer piece. In such a case, it is useful if the cable support component has markings, such as embossing or color markings, at which a cable support component piece can be cut from a longer cable support component to provide a sufficient length of the connection section.

[0016] Another advantage of such a mounting arrangement is that the end face of the cable support component to be connected to the holder can ultimately be brought up to the actual holder, for example, a head plate. This allows the cable support component connected to the holder to also be supported on the holder via its end face contacting the holder.

[0017] With this fastening arrangement, the cable support component can be mounted on the holder with its connection adapter, depending on the design, by translationally sliding the connection section of the cable support component onto the connection adapter. During this sliding, the locking element is pushed far enough into the adapter chamber that the inside of the front wall of the connection section of the cable support component can be guided past the front side of the lock, and when aligned with an opening in the front wall of the connection section, the lock springs into this. With this fastening arrangement, it is also possible to engage the cable support component with its connection section with the connection adapter by pivoting it in. By utilizing the leverage resulting from the length of the cable support component, even particularly high restoring forces acting on the locking element can be overcome.If the connecting section is designed as a non-closed profile, this leverage can also be used to press the connecting section of the cable support component onto a connecting adapter manufactured with a certain oversize. Such a connection is not only permanent, but above all, play-free. The latter also applies if the connecting section of the cable support component is designed as a closed profile, but the connecting adapter is not completely closed.

[0018] The locking member is preferably connected to the connection adapter via the at least one spring element. In this case, for example, the end face of the locking member opposite the lock is joined to the spring element. This has the advantage that a separate positive connection of the locking member to the connection adapter by appropriate contouring is then not necessary. The locking member can, for example, be a bolt with a cylindrical outer surface. This bolt can, but does not need to, have a head by which outward adjustment of the locking member is limited. In the latter case, the end face of the locking member is connected to the spring element, so that the amount of adjustment of the locking member in this regard is limited by the spring element itself.According to a preferred embodiment, a compression spring, in particular a two-leg compression spring, is provided as the spring element, which acts on the locking member in its central section, or in which central section the locking member is connected to the compression spring. The legs of such a compression spring serve not only to provide the required spring force, but also to hold the compression spring to the front wall of the connection adapter. According to one embodiment, the end sections, which are angled relative to the other leg sections, each pass through a leg opening made in the front wall of the connection adapter. These are preferably located adjacent to the opening through which the locking member passes.The design of such a compression spring as a flat band spring is particularly practical, also because the end sections of the compression spring's legs that penetrate the leg opening have only a small material thickness and therefore do not necessarily have to be recessed in the outer side of the front wall. Another advantage of using at least one spring element acting on the locking member is that, due to the spring force, the snapping of the locking member into an opening in the connecting section of the cable support component to be connected is noticeable by a clearly audible "click" sound. This provides the installer with concrete acoustic feedback that the fastening arrangement has been created as intended.

[0019] To improve the support of the cable support component connected to the connection adapter, absorbing the tilting moment and transmitting it to the connection adapter, the at least one support element of the connection adapter is located at a greater distance from the holder than the outer surface of the latch facing the holder, which engages the latch catch of the cable support component connected to the connection adapter. Thus, the outer surface of the latch member and the at least one support element are located at different positions with respect to the longitudinal extension of the connection adapter.

[0020] According to one embodiment, the connection adapter has a rectangular cross-sectional geometry. This geometry is adapted, at least in terms of its dimensions, to the internal geometry of the connection section of a cable support component to be connected to it.

[0021] The at least one support element, which, as already mentioned above, can be the end faces of the side walls facing away from the front wall, a back part formed onto a side wall, or a back connecting the side walls, has clamping structures provided on at least one of the mutually facing sides between the support element and the corresponding inner side of the connection section to improve force introduction, which clamping structures are engaged with one another in the support arrangement. This can each be a groove, with the longitudinal axes of the positive and negative structures running transversely to the longitudinal extent of the connection adapter. This measure ensures that there is a connection between the connection adapter and the cable support component connected to it on the support abutment opposite the front wall, also in the direction of force loading, with a hanging connection of the fastening arrangement on both sides.

[0022] In order to be able to engage a cable support component to be connected to the holder or the connection adapter by pivoting it into the connection adapter, a preferred embodiment provides that the side walls of the connection adapter have a smaller width in the alignment of the locking member than in the position in which the at least one support element is arranged. This allows space to slide the connection section of the cable support component to be connected over the at least one support element. Typically, the front wall and side wall ends located diagonally thereto are also notched. Such a design of the fastening arrangement is also advantageous when the at least one support element and / or the support abutment carry clamping structures, since these can then hardly be adjusted relative to one another in the direction of the longitudinal extent of the connection adapter.

[0023] The connection adapter is typically welded to the other components of the holder, for example a head plate, or formed together with it as a stamped and bent part.

[0024] The holder is typically also a cable support component, such as a head plate or headpiece to be attached to the underside of a ceiling, or a suspended pole. The cable support component to be connected to it is a suspended pole if the holder is designed as a head plate, or, in the case of a suspended pole, a bracket.

[0025] The outer surface of the locking member's latch, on its side facing the holder, is typically complementary to the contour of the latch catch of the connecting section of the cable support component to be connected or already connected to the holder. In many cases, such cable support components have a predefined hole pattern, for example, in the form of elongated holes whose long axis points in the direction of the cable support component's longitudinal extension. In such a case, the contour contacting the outer surface of the locking member is rounded, which is why in such a case the outer surface of the locking member is complementarily rounded, at least on its side facing the holder. Of course, other hole pattern geometries are also possible.For example, if a suspended support is intended to support higher loads as a cable support component, the apex can be designed to be non-curved in one section to reduce the notch effect on the rounded hole edge area. With such a design, the outer surface of the control element facing the holder then has a complementary outer geometry.

[0026] The latch of the locking member preferably extends through the latch catch of the connecting section of the cable support component. This means that in the fastening arrangement, a portion of the latch protrudes from the latch catch. Due to the external arrangement of the connecting section, this protruding portion is visible. According to one embodiment, this is used to color-code the portion of the latch protruding from the latch catch, in order to clearly indicate visually that the locking member has sufficiently penetrated the latch catch as intended. Thus, with such a design of the fastening arrangement, an installer receives two forms of feedback – an acoustic one, as mentioned above, and a visual one when the fastening arrangement has been created as intended.

[0027] The end face of the bolt engaging into the latch or preferably passing through it can be designed with a tool engagement contour, for example a central recess, in order to be able to attach a tool, for example a screwdriver, to press in the locking member and thus to release the fastening arrangement.

[0028] The end face of the bolt that engages with or passes through the locking latch typically has at least one adjusting bevel. This is located on the side of the end face facing away from the other components of the holder and is typically designed as a chamfer on the end opposite the holder, between the end face and the outer surface. During assembly, the cable support component to be connected is brought up to this, whereby the locking member is pressed into the connection adapter against the force of the at least one spring element, so that no separate actuation of the locking member is required to adjust the locking member for mounting the cable support component. A chamfer can also be provided as an adjusting bevel on the opposite outer surface facing the holder; this is typically much smaller than the adjusting bevel mentioned above. This serves to facilitate the release of the fastening arrangement.

[0029] Although the fastening arrangement with its connection adapter is described above with only one locking element, such a system can also comprise several locking elements, for example, two. According to one exemplary embodiment, these are arranged one above the other, so that each locking element, with its locking element, engages through a locking latch of the cable support component to be connected.

[0030] Additionally, the connection adapter can be equipped with additional locking lugs on both of its side walls, each of which engages with an opening in the hole pattern of the side walls of the connecting section of the cable support component. With such a configuration, it is preferred for the connecting section to be open on the side of its support abutment, so that the expansion elasticity of the side walls of the connecting section of the cable support component can be utilized for the insertion of such locking lugs.

[0031] The invention is described below using an exemplary embodiment with reference to the accompanying figures. They show: Fig. 1: A perspective view of a fastening arrangement according to the invention, comprising a holder and a cable support component in the manner of an exploded view, Fig. 2: a perspective view of the holder of the fastening arrangement of the Fig. 1 from a first perspective, Fig. 3: a perspective view of the holder of the fastening arrangement of the Fig. 1 from a different perspective, Fig. 4a-4d: a sequence of figures to illustrate the assembly movement for connecting the cable support component to the holder to create the fastening arrangement of the Fig. 1, Fig. 5: a front view of the mounting arrangement of the Fig. 1, Fig. 6: an enlarged sectional view through the upper end of the fastening arrangement of the Fig. 5 along the line A - A and Fig. 7: a cross-section through the fastening arrangement of the Fig. 5 along the section line B - B.

[0032] A fastening arrangement 1 comprises a holder 2 and a hanging post 3 as a cable support component connected to the holder 2. The holder 2 of the illustrated embodiment has a head plate 4 with which the holder 2 can be fastened to the underside of a ceiling. For this purpose, the head plate 4 has corresponding fastening openings for the passage of a fastener each. A connection adapter 5 is connected to the head plate 4, wherein the connection of the connection adapter 5 to the head plate 4 is provided in the illustrated embodiment by a joint (welded connection). The connection adapter 5 protrudes from the underside of the head plate 4 and forms a positive structure with respect to the plane of the head plate 4. Part of the connection adapter 5 is a locking member 6, which is fastened to a two-legged compression spring 7 designed as a strip spring.The compression spring 7 has a central section 8, which in the illustrated embodiment is slightly wider than the legs 9, 9.1 formed thereon. The end sections 10, 10.1 of the legs 9, 9.1 are beveled outwards, pointing away from each other. The remaining part of the connection adapter 5 in the illustrated embodiment is a machined square profile piece A with rounded edges. This profile piece A has a front wall 11, two side walls 12, 12.1 connected to it, and in the illustrated embodiment, a back 13 connecting the two side walls 12, 12.1 on their side opposite the front wall 11. An opening 14 for the locking member 6 to pass through is made in the front wall 11.At a distance from the opening 14, two leg openings 15, 15.1 are introduced into the front wall 11, opposite each other in the direction of the longitudinal extension of the connection adapter 5 with respect to the opening 14. The leg openings 15, 15.1 serve to connect the compression spring 7 with the locking member 6 to the front wall 11. The front wall 11, the side walls 12, 12.1 and the back 13 enclose an adapter chamber 16 in which the remaining sections of the compression spring 7 and a part of the locking member 6 are located.

[0033] The locking member 6 of the illustrated embodiment is designed as a bolt with a cylindrical outer surface. It is also entirely possible to design the locking member with a slight taper toward its free end face, for example, 1° to 2°.

[0034] The suspended support 3 serving as the cable support component in the illustrated embodiment is a C-shaped profile with folded back sections. Thus, the suspended support 3 comprises a front wall 17, two side walls 18, 18.1 formed thereon, and two support abutments formed by the C-shaped profile with folded back sections through the folded back end faces 19, 19.1. A hole pattern is incorporated into the front wall 17 and the side walls 18, 18.1. The openings 20 in the front wall 17 of the suspended support 3 are designed as elongated holes, with the ends pointing in the longitudinal direction of the suspended support 3 being curved. The openings in the two side walls 18, 18.1 have the same geometry. The openings 20 made in the front wall 17 serve as a locking latch for receiving the front section of the locking member 6 serving as a bolt.A marking 21, which in the illustrated embodiment is provided by a shallow embossing, is provided between two adjacent openings 20 in the direction of the longitudinal extension of the hanging post 3. The markings 21 serve the purpose of precisely cutting the hanging post to length for the fastening arrangement 1 so that the end face of the connecting section 26 rests against the underside of the head plate 4. The marking shown in . Fig. The uppermost section of the hanging post 3, which can be seen in Figure 1, serves as a connection section for connecting the hanging post 3 to the holder 2. An adapter receptacle 22 is enclosed by the front wall 17, the side walls 18, 18.1 formed thereon and the remaining profiling of the hanging post 3. This represents a negative structure with respect to the connection adapter 5. Both structures 5, 22 are dimensionally coordinated with one another so that they can be engaged with one another.

[0035] Fig. Figure 2 shows a perspective view of the holder 2 in its use position with the compression spring 7 mounted on the front wall 11 of the profile piece A and supporting the locking member 6. The end sections 10, 10.1 extend through the leg openings 15, 15.1 and rest against the outer side of the front wall 11. The locking member 6 protrudes from the opening 14 with its section serving as a latch 23. The latch member 6 can be translationally adjusted into the adapter chamber 16 against the restoring force of the compression spring 7. The end face of the locking member facing away from the compression spring 7 - the free end of the latch 23 - is structured by a lower adjustment bevel 24 further away from the head plate 4 and an upper adjustment bevel 25 closer to the head plate 4. The adjusting bevels 24, 25 run transversely to the longitudinal extent of the connection adapter 5 with respect to their planar extension. The adjusting bevel 24 is longer than the adjusting bevel 25.Both adjusting bevels 24, 25 serve the purpose of pressing the locking member 6 into the front wall 11 with the connecting section of the hanging post 3 as a cable support component on the holder 2 during assembly or disassembly of the hanging post 3 as a cable support component so far that the unperforated end section of the connecting section 26 can be guided over the bolt 23 of the locking member 6 so that it can spring into the uppermost opening 20 as a locking latch of the front wall 17 of the connecting section 26 of the hanging post 3 during further assembly.

[0036] In the illustrated embodiment, the connection adapter 5 is designed so that the hanging rod 3 with its connection section 26 (see Fig. 1) can be engaged with the connection adapter 5 by performing a pivoting movement. For this purpose, the side walls 12, 12.1 of the connection adapter 5 are designed with a smaller width in the alignment of the locking member 6 than in the area of ​​the back 13. In the illustrated embodiment, the end of the side walls 12, 12.1 pointing away from the front wall 11 is inclined, with a width that decreases towards the head plate 4. This inclined end of the side walls 12, 12.1 is identified in the figures by the reference numeral 27. Diagonally opposite the inclined end 27, the front wall 11 is also notched with the same inclination, whereby this notch extends into the side walls 12, 12.1.

[0037] The spine 13 is grooved 28 (see Fig. 3), whereby the longitudinal axis of the grooving runs transversely to the longitudinal axis of the connection adapter 5.

[0038] This grooving 28 serves as a clamping structure that acts against the end faces 19, 19.1 of the back edge of the connecting section 26 of the suspended support 3. The end faces 19, 19.1 of the suspended support 3 are, as can be seen from Fig. 1, also designed with clamping structures.

[0039] With respect to the longitudinal extension of the connection adapter 5, the locking member 6 with its locking bar 23 is located at a position closer to the head plate 4 than the back 13 with its groove 28. This offset is shown in the Fig. 2 and Fig. 3 can be clearly seen.

[0040] In the illustrated embodiment, the circumferential dimension of the connection adapter 5 has a slight oversize compared to the inner width of the connection section 26 of the hanging rod 3. The oversize amounts to a few tenths of a millimeter.

[0041] The suspended support 3 is mounted as a cable support component on the holder 2 by performing a push-on and pivoting movement. This is shown in the sequence of figures 4a to 4d. In a first assembly step, the connecting section 26 of the cable support component 3 is pushed onto the lower section of the connecting adapter 5 of the holder 2, whereby the inside of the front wall 17 of the suspended support 3 is guided past the notch of the front wall 11 of the connecting adapter 5. This position between the suspended support 3 and the holder 2 is shown in Fig. 4a. Subsequently, while simultaneously pushing the suspension rod 3 further onto the connection adapter 5, a pivoting movement of the suspension rod 3 is carried out. This is indicated by an arrow in Fig. 4b. The sliding movement is limited by contact between the connecting section 26 of the hanging post 3 and its front edge of the back edge on the underside of the head plate 4 (see Fig. 4b). As the pivoting continues, the inner side of the front wall 17 of the connecting section 26 contacts the end face of the latch 23, so that by continuing the pivoting movement, the latch member 6 is pressed into the adapter chamber 16 of the connecting adapter 5. If the latch 23 is aligned with the uppermost opening 20 of the front wall 17 of the suspended post 3, the latch springs into this opening 20 as a latch latch, thus providing the fastening arrangement.

[0042] Due to the length of the hanging rod 3, a high actuating force can be exerted on the locking member 6 by the pivoting movement, as well as the force required to widen the connecting section 26 of the hanging rod 3, so that the connecting adapter 5, which is manufactured with a certain excess compared to the inner width of the connecting section 26, can be inserted into the receiving section 26 as a positive structure.

[0043] This ensures a play-free fit between the connection adapter 5 and the connection section 26 of the hanging rod 3.

[0044] Fig. 4d shows the fastening arrangement 1, wherein in nature the bolt 23 passes through the uppermost opening 20 of the front wall 17 and protrudes with a significantly longer section over the outside of the front wall 17 (see also Fig. 6). The free end face of the connecting section 26 contacts the underside of the head plate 4 in the fastening arrangement 1.

[0045] In the sequence of figures 4a to 4d, the hanging rod 3 is shown transparently in order to be able to show the successive engagement of its connecting section 26 with the connecting adapter 5.

[0046] The radius of the outer surface of the locking member 6 facing the head plate 4 is adapted, at least in its locking section 23, to the radius of the corresponding end of the opening 20 of the hanging post 3 (see also Fig. 5).

[0047] The longitudinal representation of the Fig. 6 of the fastening arrangement 1 shows the connection of the connecting section 26 of the hanging rod 3 to the holder 2. The front wall 7 of the hanging rod 3 hangs on the section of the locking member 6 forming the bolt 23. Due to the Fig. 6 recognizable height offset between the locking member 6 or its locking member 23 and the back 13, the latter is pressed with its grooving 28 against the end faces 19, 19.1 of the back edge, which are also equipped with clamping structures, so that a load introduction is coupled into the connection adapter 5 both via the front wall 17 and via the back edges and thus via the front wall 11 and the back 13.

[0048] The play-free fitting of the connection adapter 5 into the adapter receptacle 22 of the connection section 26 of the hanging rod 3 is shown in the cross-sectional view of the Fig. 7.
