Description

[0001] The invention relates to a closing device for the lateral edging of a usable area of a balcony or terrace that can be covered with a floor covering, wherein the closing device comprises an end profile with an anchoring leg that can be placed on the usable area and with a drainage channel that is designed or can be fixed to the end profile in such a way that water flowing over the usable area can be collected in the drainage channel and drained away, wherein the drainage channel and the closing profile are connected to one another via at least one rod-shaped fastening element, and wherein a fastening element seat and a receiving section are designed on the drainage channel and on the end profile in such a way that the fastening element that is positively fixed in the fastening element seat and positively fixed in the receiving section effects a height-adjustable fixing of the drainage channel to the end profile.

[0002] Numerous different finishing devices are known from practice for edging the sides of a floor covering laid on a terrace or balcony. Such edging not only reliably secures the edge of the floor covering, or individual floor covering elements arranged at the edge of the usable area, but often also provides an aesthetically pleasing covering for the end face of the floor covering along a perimeter edge.

[0003] Many such finishing devices have a finishing profile that can be arranged along a side edge of the usable area. The finishing profile can be used to secure and glue a film or drainage mat, which is often waterproof, along the side edge. In many cases, a finishing profile is also suitable for edging the floor covering lying on the usable area laterally. Most finishing profiles known from practice have an anchoring leg that can be placed on the usable area and can, for example, be glued to the usable area or anchored to the usable area together with the floor covering arranged on it. A downwardly projecting stop leg, which is formed on the finishing profile, can be used to provide a lateral stop for the finishing profile at the side edge of the usable area.In addition, an upstand can protrude upwards and often vertically from an end of the anchoring leg, which usually projects beyond the side edge of the usable area, at least partially covering a side edge of a floor covering element resting on the anchoring leg, thereby forming a form-fitting lateral border for the edge of the floor covering. The upstand also forms an often flat lateral cover for one end of the floor covering resting on the usable area and the anchoring leg. A side edge of the usable area of a balcony or terrace covered with the floor covering can be covered with a downwardly projecting covering leg, which is designed either as a separate covering leg in addition to an upwardly projecting upstand or as a downwardly projecting section of an upstand that projects both upwards and downwards.Such a finishing profile is shown and described, for example, in DE 296 06 490 U1.

[0004] A downwardly projecting cover leg can also have a bevel or recess directed away from the usable area to direct water flowing down the side of the cover leg away from a side edge of the usable area of a balcony or terrace covered with the flooring. For example, EP 0 882 856 A2 describes such a water-draining end profile.

[0005] There are also practical situations where floor coverings can be laid in areas where large amounts of precipitation can fall onto the floor covering and must be drained away laterally via the side edging of the floor covering. Particularly on balconies, it is important to prevent large amounts of precipitation from flowing uncontrollably over the edge of the balcony and either trickling down an adjacent wall surface below or dripping from the lower edge of the balcony. For this purpose, it is known to provide a drainage channel below the floor covering on an end profile that laterally borders the floor covering. This channel can collect and drain away the water flowing off the upper side of the floor covering.In some end profiles, such a drainage channel is formed in one piece and usually projects vertically downwards from the anchoring leg which is arranged horizontally and rests on the usable surface.

[0006] In contrast, many of the closure systems known in practice have a drainage channel manufactured separately and can be connected to the closure profile on-site if necessary. For example, DE 10 2013 102 587 A1 or EP 0 828 037 show and describe closure systems in which a downwardly projecting leg of the closure profile has hooks or fastening elements for attaching or securing a separately manufactured drainage channel.

[0007] To ensure reliable drainage of the wastewater collected by the drainage channel, it is often necessary for the drainage channel to have a gradient toward a downward-facing water outlet. Such a gradient is often difficult and requires considerable effort to achieve with drainage channels that can be hooked into a fastening leg of a finishing profile. Such an installation situation is described, for example, in DE 10 2013 102 587 A1. It is therefore also known from practice that a downward-projecting fastening leg of a finishing profile has a flat guide surface to which the drainage channel can be placed and secured.When the end fitting is installed as intended, the drainage channel and the guide surface have vertically aligned slots and corresponding recesses, allowing the drainage channel to be moved along the slots and screwed to the guide surface with a lateral slope. In DE 195 35 187 A1, the drainage channel is also guided and movable via slots. Attaching a drainage channel to such an end profile is comparatively complex and requires considerable installation effort, particularly for specifying the desired lateral slope.

[0008] In addition, with this type of drainage channel attachment, the elongated holes and the clamps or screws used for fastening are usually visible. To ensure an aesthetically pleasing overall appearance of the drainage channel, a separate covering must be provided for the attachment areas or the entire guide surface.

[0009] For example, from DE 199 15 347 C1 or US 1 564 032, closure devices are known in which the drainage channel and the closure profile are connected to one another via at least one rod-shaped fastening element. In the closure device according to DE 199 15 347 C1, the rod-shaped fastening element is arranged transversely to a displacement direction of the drainage channel and serves to fix the drainage channel in a previously predetermined and adjusted position of the drainage channel relative to the closure profile to which the drainage channel is attached. In the closure device shown in US 1 564 032, a threaded rod is fixed in a roof structure and arranged such that it serves as a rod-shaped fastening element for the drainage channel, which can be displaced along the threaded rod. The threaded rod represents a visually striking and complex fastening of the drainage channel to the closure profile.

[0010] It is therefore considered an object of the present invention to design such a closure device in such a way that the drainage channel can be easily attached to the closure profile and aligned to achieve the desired gradient. Furthermore, an optional, aesthetically pleasing lateral edging of the usable area should be easily enabled.

[0011] This object is achieved according to the invention in that the end profile has a guide leg which protrudes from the anchoring leg and is aligned parallel to the orientation of the fastening screw connecting the end profile to the drainage channel, against which the drainage channel rests and is guided.

[0012] The rod-shaped fastening element can, for example, be a rod with a corrugated or otherwise profiled outer surface, wherein the corrugated or profiled outer surface can engage in a form-fitting manner with an inner surface of the receiving section that is adapted thereto. For height adjustment, the receiving section can, for example, surround the outer surface in various positions along the axial direction and be fixed in a locking manner. The form-fitting engagement of the three-dimensionally structured outer surface with the surrounding receiving section can advantageously be designed such that an axial displacement of the receiving section along the axial direction of the rod-shaped fastening element is possible manually and without special tools, but the drainage channel is sufficiently firmly fixed to the end profile at the desired height or at the desired distance from the anchoring leg.

[0013] A side wall of the guide leg forms a contact surface for the drainage channel, allowing the drainage channel to rest against the guide leg, regardless of the distance from the anchoring leg specified on site in each individual case, and also regardless of an individually specified gradient, and thus be reliably secured to the end profile. The flat design of the guide leg's contact surface enables simple and continuous height adjustment of the drainage channel relative to the end profile, independent of the design of the edge area of the subsurface on which the end profile rests. Furthermore, the guide leg can form an aesthetically pleasing facing for a transition area between the end profile and the drainage channel.

[0014] In order to be able to arrange the drainage channel as close as possible to a side edge of a balcony or terrace, it is optionally provided that the screw thread section is arranged on the drainage channel in such a way that a fastening screw extending through the screw thread section protrudes into an interior of the drainage channel. In this case, the drainage channel expediently has a sufficiently large depth, measured from a bottom of the drainage channel to an upper edge of a side wall of the drainage channel, so that the fastening screw can penetrate essentially completely into the interior of the drainage channel and a maximum height adjustment of the drainage channel relative to the end profile is possible.

[0015] With a view to a particularly aesthetically pleasing design of the closing device, it is optionally provided that the rod-shaped fastening element is arranged in a gap between the guide leg and a side wall of the drainage channel. The rod-shaped fastening element can thus protrude into the interior of the drainage channel invisibly from the outside. When installed, only one end of the closing profile, a downwardly projecting guide leg, and the drainage channel attached to the closing profile are visible from the closing device, while all provided fastening elements and the respective fastening element seats and receiving sections required for attaching the drainage channel to the closing profile can be completely concealed by the guide leg and therefore invisible to the observer.Furthermore, the guide leg does not hinder the insertion of the rod-shaped fastening element, which is aligned parallel to the guide leg and whose fastening element seat is not covered by the guide leg.

[0016] It is also advantageous to provide for the guide leg to extend into the interior of the drainage channel. The rod-shaped fastening element can then be arranged in a narrow gap between the guide leg and a side wall of the drainage channel facing the usable area. Even with such a configuration, the guide leg can conceal the rod-shaped fastening element, thereby creating a visually appealing overall impression.

[0017] To facilitate the most reliable installation of the drainage channel on the end profile, one embodiment of the inventive concept provides for a stop for the drainage channel guided on the guide leg to be formed at an end of the guide leg protruding from the anchoring leg. The drainage channel can therefore only be arranged in a height-adjustable manner within a range defined by the guide leg, with this range being defined at one end by a stop of the drainage channel on the anchoring leg of the end profile and being limited at the end of the guide leg protruding from the anchoring leg by the stop formed there.In this way, it can be avoided that during assembly or during a height adjustment process, too great a distance between the drainage channel and the anchoring leg of the end profile can be accidentally specified and the drainage channel could become detached from the end profile and fall down due to further displacement of the receiving section along the rod-shaped fastening element.

[0018] According to a particularly advantageous embodiment of the inventive concept, the rod-shaped fastening element is a fastening screw, and the receiving section has a screw thread section adapted to the fastening screw. The drainage channel and the end profile are connected to one another via at least one fastening screw, wherein a screw seat and a screw thread section are formed on the drainage channel and on the end profile such that the fastening screw, secured in the screw seat and screwed into the screw thread section, ensures a height-adjustable attachment of the drainage channel to the end profile.The fastening screw is expediently aligned perpendicular and in any case not parallel to the anchoring leg, so that by turning the fastening screw fixed in the screw seat, the screw thread section engaging with the fastening screw changes its distance from the anchoring leg and thus the distance between the drainage channel and the anchoring leg can be changed accordingly. The drainage channel is expediently attached to the end profile with two fastening screws, with the two fastening screws being spaced apart along the end profile. Particularly in the case of long drainage channels, the drainage channel can also be attached to the end profile with more than two fastening screws. For each fastening screw, the distance between the screw seat and the screw thread section that can be moved along the fastening screw can then be individually specified.By specifying this distance differently for the two fastening screws, a different distance between the drainage channel and the anchoring leg of the end profile can be set for two areas arranged at a distance from each other and thus a gradient of the drainage channel can be specified.

[0019] It is conceivable that a drainage channel along a larger balcony or terrace could be composed of several rigid drainage channel segments. Each individual drainage channel segment is then conveniently secured to the end profile with two fasteners or fastening screws, allowing each drainage channel segment to be individually height-adjusted to the end profile and to have an individually preset gradient.

[0020] For the height-adjustable fixing of the drainage channel to the end profile, it is only necessary that the receiving section can be displaced along a longitudinal axis of a rod-shaped fastening element or along an alignment of the fastening screw relative to the fastening element seat or screw seat.In principle, it is possible to either arrange the fastening element seat on the end profile and to provide the drainage channel with a receiving section and to be able to displace it relative to the end profile via the fastening element fixed in the fastening element seat of the end profile, or to form the fastening element seat on the drainage channel and to form the receiving section on the end profile, so that by displacing the fastening element relative to the receiving section along the longitudinal axis of the fastening element, the fastening element fixed in the fastening element seat on the drainage channel can be displaced together with the drainage channel relative to the end profile.

[0021] With conventional adjustment options, in which the drainage channel and the end profile are secured to one another using clamping screws or clamp fastenings that pass through elongated holes, a complex manual alignment of the drainage channel relative to the end profile is necessary before a clamping fixation. In contrast, with the inventive connection of the drainage channel to the end profile, the fastening elements arranged according to the invention allow a simple height adjustment of the drainage channel already connected to the end profile by either displacing the rod-shaped fastening element relative to the receiving section or turning the fastening screw in the screw thread section. Manual alignment and holding the drainage channel in the desired orientation is not required.This can significantly reduce the installation effort on site and make it easier to reliably specify the desired gradient of the drainage channel.

[0022] According to an advantageous embodiment of the inventive concept, the drainage channel has a screw thread section in an upper edge region and a recess for receiving the fastening screw is formed in the anchoring leg of the end profile, so that the fastening screw extends through the recess in the end profile into the screw thread section of the drainage channel and the fastening screw is accessible and can be turned from a side of the end profile opposite the drainage channel. With such an arrangement of the fastening screw, it is easily accessible from an upper side of the end profile. The drainage channel can be easily attached to the end profile and then aligned or provided with the desired gradient by suitable and individual turning of the individual fastening screws.The desired flooring can then be installed on top of the end profile. The fastening screw can be concealed by a flooring element on top to create a particularly aesthetically pleasing overall impression of the end profile, with no visible fastening screws.

[0023] To facilitate reliable positioning of the end profile along the side edge of the usable area, the end profile can optionally have a stop leg that protrudes from the anchoring leg at an angle to the latter, forming a lateral stop for a peripheral edge of a subfloor. Furthermore, the end profile can also optionally have an upstand at one end of the anchoring leg, which protrudes at an angle from the anchoring leg and can be used to at least partially surround the end face of a floor covering element resting on the anchoring leg.

[0024] With a view to the most advantageous drainage properties possible, according to an advantageous embodiment of the inventive concept, it is provided that passage openings are formed in the anchoring leg adjacent to the upstand, through which openings water or moisture can reach the drainage channel arranged underneath. The anchoring leg can optionally have a gradient sloping down towards the upstand in a section adjacent to the upwardly projecting upstand, in which the passage openings are arranged. This creates a slightly lower drainage channel between a region of the anchoring leg resting on the usable surface of the balcony or terrace, on the one hand, and the upstand, on the other hand, in which drainage channel rainwater hitting the usable surface from above or moisture escaping from the floor covering can collect and flow through the passage openings into the drainage channel.However, the passage openings can also be formed exclusively or additionally in the upstand, or can extend into the upstand.

[0025] According to an optional embodiment, it may be expedient for the passage openings to be arranged adjacent to the guide leg in the anchoring leg, allowing water passing through the passage openings to flow down the side of the guide leg and into the drainage channel. This prevents water passing through the passage openings from initially collecting at the lower edge of a passage opening and then having to drip down. By arranging the passage openings adjacent to the guide leg, the water passing through can flow down the side of the guide leg, thereby promoting reliable drainage and preventing otherwise forced dripping.In this way, especially in the case of large quantities of water that hit the usable area, for example due to precipitation, and which must be drained away, or in the case of strong winds, the drops forming at the openings can drip down uncontrollably and may not be able to be collected by the drainage channel.

[0026] Furthermore, according to an advantageous embodiment of the inventive concept, it is possible for a receiving opening of the drainage channel to be covered with a water-permeable cover. The drainage channel can be designed, for example, as a folded or continuously curved U-profile. A receiving opening of the drainage channel delimited by leg ends of the profile can be covered by a perforated sheet or a plug-on attachment, wherein the attachment has a frame and a water-permeable cover element arranged in the frame. The frame can be clipped or plugged onto one leg end or onto both leg ends. It is also conceivable for one leg end of the U-profile-shaped drainage channel to be folded and bent over in such a way that the folded section partially or essentially completely covers the receiving opening of the drainage channel.This bent area can have water-permeable recesses, holes or slots, which can be conveniently introduced into the subsequently bent section of the leg end before a deformation process.

[0027] The following are examples of the inventive concept that are illustrated in the drawing. It shows: Figure 1 a sectional view of a finishing profile arranged along the edge of a balcony with a drainage channel attached to it, Figure 2 a comparable sectional view of a differently designed closure device, Figure 3 another sectional view of a differently designed closure device, Figure 4a side view of an edge of a balcony with a closing device arranged thereon, wherein two drainage channel sections are arranged next to each other on a continuous closing profile and form a continuous drainage channel with a gradient relative to a surface of the usable area of the balcony, Figure 5 a sectional view of another, again differently designed, closure device, Figure 6 a sectional view of a receiving section with a screw thread section and part of a fastening screw, and Figure 7 a sectional view of a receiving section with a part of a rod-shaped fastening element with a wave-shaped profiled outer surface.

[0028] In the Figures 1 to 5Various embodiments of a closing device 1 according to the invention for laterally enclosing a usable area 2 of a balcony or terrace are shown schematically by way of example. The closing device 1 has a closing profile 3 with an anchoring leg 4 which, when the closing profile 3 is arranged as intended, rests horizontally on an edge region of a subsurface 5 of the usable area 2 and extends from an edge 6 of the subsurface 5 into the usable area 2. The anchoring leg 4 serves to anchor the closing profile 3 to the edge region of the subsurface 5. A floor covering composed of individual floor covering elements 7 is laid on the usable area 2. The floor covering elements 7 also rest on the anchoring leg 4 resting on the subsurface 5 in the edge region and cover it.

[0029] The end profile 3 has a vertically upwardly projecting upstand 8 at an end of the anchoring leg 4 that extends beyond the edge area of the substrate 5. The upstand 8 is expediently dimensioned such that the upstand 8 covers a front surface 9 of the adjacent floor covering elements 7. The upstand 8 forms a form-fitting boundary and enclosure for the floor covering elements 7 and thus for the floor covering 6 laid on the substrate 5 of the usable area 2.

[0030] In an area 10 adjacent to the upstand 8, the anchoring leg 4 has a downward slope towards the upstand 8. This strip-shaped area 10 extending along the upstand 8 forms a channel that is deeper than the anchoring leg 4. This channel can also be formed by a groove-shaped depression. In this area 10, a number of passage openings 11 are arranged spaced apart from one another along the upstand 8. Rainwater striking a surface of the floor covering and flowing down over the end face 9, as well as any moisture droplets accumulating beneath the floor covering elements 7 and emerging laterally at the end face 9, are initially collected in the channel and can then flow downward through the passage openings 11. This promotes drainage and dehumidification of the floor covering on the usable area 2.

[0031] The Figure 1 The end profile 3 shown has, at a distance from the edge 6 of the substrate 5, a guide leg 12 extending downwards from the horizontally running anchoring leg 4. A screw seat 14 is formed between a stop leg 13 projecting downwards from the anchoring leg 4, which rests against the edge 6 of the substrate 5, and the guide leg 12. A fastening screw 15 is rotatably mounted in this screw seat 14. A drainage channel 16 is fixed to the fastening screw 15, which is attached to the end profile 3 below the anchoring leg 4 and thus also below the floor covering and the passage openings 11. The drainage channel 16 ensures a controlled lateral drainage of the water flowing or dripping downwards through the passage openings 11.

[0032] The drainage channel 16 has a substantially U-shaped collecting profile with a drainage channel base 17 and two side legs 18, 19 arranged opposite one another and projecting upwards from the drainage channel base 17, which form two side walls of the drainage channel 16. On the side of the drainage channel 16 facing the substrate 5, a screw-threaded section 20 is attached or formed on the side leg 19. The fastening screw 15 is screwed into the screw-threaded section 20 and engages with the screw-threaded section 20. By turning the fastening screw 15, the fastening screw 15 mounted in the screw seat 14 does not move along the axial direction predetermined by its axis of rotation.However, when the fastening screw 15 is turned, the screw thread section 20 of the drainage channel 16, which is mounted on the end profile 3 in a rotationally fixed manner by two or more fastening screws 15 arranged at a distance from one another, is displaced in the axial direction, so that the distance of the drainage channel 16 from the horizontally extending anchoring leg 4 changes accordingly. In this way, by turning the fastening screw 15, the distance of the drainage channel 16 relative to the floor covering and the cover leg 8 can be adjusted and specified within a range predetermined by a usable thread length of the fastening screw 15.

[0033] The screw thread section 20 arranged on the drainage channel 16 has a flat guide surface 21 which, when the drainage channel 16 is mounted as intended, rests against a contact surface 22 of the guide leg 12 facing the screw thread section 20. The guide leg 12 thus forms a positive guide for the screw thread section 20, which can be displaced in the axial direction along the fastening screw 15, and thus also for the drainage channel 16. The guide leg 12 has a laterally projecting stop 23 at its lower end protruding from the anchoring leg 4, which prevents axial displacement of the screw thread section 20 and thus of the drainage channel 16 beyond the area limited by this stop 23.

[0034] The guide leg 12 projects into an interior space 24 of the drainage channel 16. The fastening screw 15 is arranged in a narrow area between the guide leg 12 and the side leg 19 facing the substrate 5 and is concealed by the guide leg 12 from an outside observer.

[0035] An end region 25 of the side leg 18 facing away from the subsurface 5 of the balcony or terrace is beveled such that the end region 25 forms a water-permeable cover 26 that largely covers the interior 24 of the drainage channel 16. Numerous openings 27 are formed in this cover 26, through which the water dripping through the passage openings 11 can penetrate into the interior 24 of the drainage channel 16 and be drained therein. Undesirable contamination of the drainage channel 16 by larger dirt particles or, for example, by leaves falling onto the drainage channel 16 can be prevented with the water-permeable cover 26.

[0036] In the Figure 2In the illustrated embodiment of a closure device 1 according to the invention, the downwardly projecting guide leg 12 simultaneously forms a lateral stop for the edge 6 of the substrate 5, which is why no additional stop leg 13 is formed projecting from the anchoring leg 4. The screw seat 14 is formed on the guide leg 12 at its end projecting from the anchoring leg 4. The fastening screw 15 is fixed to the screw seat 14 by a lock nut 27 fastened to the fastening screw 15 in a rotationally fixed manner and is non-displaceable in the axial direction but rotatable. On the side leg 19 facing the substrate 5, the screw thread section 20 is arranged on an outer side facing the balcony or terrace.By turning the fastening screw 15, which is accessible from below, the engaged screw thread section 20 and thus the drainage channel 16 can be adjusted relative to the end profile 3 in height or in distance from the anchoring leg 4. In this embodiment, too, the flat contact surface 22 of the guide leg 12 forms a positive guide for the guide surface 21 of the screw thread section 20.

[0037] In the Figure 3In the illustrated embodiment, the fastening screw 15, which can be inserted into a screw seat 14, has a slot 29 at an opposite screw end 28, so that the fastening screw 15 can be turned with a suitable tool introduced from below, which tool is brought into engagement with the slot 29. The side leg 19 facing the substrate 5 lies flat against the flat contact surface 22 of the guide leg 12, so that the drainage channel 16 is positively guided on the contact surface 22 of the guide leg 12 during a height adjustment. A cover 26 is clamped onto a leg end 30 of the side leg 18 facing away from the substrate 5. The cover 26 has a water-permeable net 32 tensioned in a circumferential frame 31 of the cover, with which undesirable contamination of the interior 24 of the drainage channel 16 can be prevented.

[0038] In Figure 41 shows a side view of a closing device 1 according to the invention, which is arranged along an edge 6 of a subfloor 5 of a usable area 2 of a balcony or terrace, said edge 6 being concealed by the closing device 1 in this view. From this side, in the assembled state of the closing device 1, only the upwardly projecting upstand 8, the downwardly projecting guide leg 12 and the drainage channel 16 fixed to the closing profile 3, or the side leg 18 of the drainage channel 16 facing the viewer, are visible. The fastening screws 15, shown in dashed lines for clarity, are arranged on a rear side of the guide leg 12 facing away from the viewer and are concealed by the guide leg 12.The drainage channel 16 is composed, merely by way of example, of two drainage channel segments 33 which merge into one another and has, along the edge 6, a section which is shown in the illustration according to . Figure 4 slope sloping to the right.

[0039] In the Figure 5 In the exemplary embodiment shown, the end profile 3 does not have an upwardly projecting edge. On such an end profile 3, floor covering edge elements 34 with a downwardly curved edge region can be laid along a side edge of the usable area. Such an end profile 3 is usually used to bond and thereby fix a film-like seal 35 arranged between the substrate 5 and the floor covering elements 7 and 34 to an upper side of the anchoring leg 4 or even underneath it.

[0040] The downwardly projecting stop leg 13 is arranged directly next to the fastening screw 15 and forms a lateral forced guide for the fastening screw 15, whereby the stability of the closing device 1 is further increased and improved during assembly.

[0041] The drainage channel 16 has two inwardly directed protrusions 36 on opposite inner side regions of the side legs 18, 19 at a distance from the leg end 30 of the side leg 18 facing away from the substrate 5. These protrusions 36 form a support for a strip-shaped, water-permeable cover 26, which can optionally be inserted into the drainage channel 16.

[0042] In Figure 6By way of example, a lower end 37 of a self-tapping fastening screw 15 and a receiving section 20 adapted thereto with wave-shaped inner surfaces 38 are shown. The self-tapping fastening screw 15 can penetrate a connecting area 39 while being screwed into the receiving section 20.

[0043] In Figure 7For illustration purposes, a rod-shaped fastening element 40 with a corrugated outer surface 41 is shown as an example of a fastening element 40 that is not a fastening screw. The receiving section 42 adapted thereto also has corrugated inner surfaces 43. The rod-shaped fastening element 40 can be secured in various positions along the longitudinal direction of the rod-shaped fastening element 40 in the receiving section 42, wherein the corrugated outer surface 41 engages in a form-fitting manner with the corrugated inner surfaces 43 of the receiving section 42. The receiving section 42 has a deformability such that the rod-shaped fastening element 40 can be displaced in the receiving section 42 along the longitudinal direction, but is reliably secured and fixed in the desired position.
