Description

The invention relates to a fastening system for a shading system for shading a building opening, having the features of the preamble of claim 1.

The shading system is typically used to shade glazed building openings, such as windows or doors, as areas to be shaded. Such shading systems are designed for subsequent assembly. They have a fastening system with the help of which a hanging, in particular a pleated fabric folded several times, is fastened to the building opening for shading. The fastening system typically has a lower and an upper operating profile, between which the hanging is arranged. The two operating profiles can be moved along tensioning cords and positioned at any position along the tensioning cords. The tensioning cords are each attached to a holder at the top and at the bottom of the building opening, in particular on a frame. The holder is firmly fixed so that the tension cords are stretched between two upper holders and two lower holders. The tensioning cords are threaded through the curtain and are each guided into the respective operating profile and leave this, for example, at the front via a so-called slide in the direction of the respective holder. The curtain is often interchangeable.

The two operating profiles are freely adjustable along the tension cords. In their end position, the operating profiles are as close as possible to the frame, so that an undesirable light gap between the operating profile and the frame is avoided. In order to fix this end position of the operating profiles, it is, for example, from EP 1 526 246 A2 or that EP 3 330 475 A2 known to fix the operating profile by means of magnetic force on the holder. According to the EP 1 526 246 A2 the holder has a magnetic plate which exerts a magnetic holding force on the operating profile. According to the EP 3 330 475 A2 a magnetic element is integrated into the slide used in the operating profile.

Proceeding from this, the invention is based on the object of specifying a fastening system for a shading system in which reliable magnetic mounting of an operating profile on a holder is made possible.

The object is achieved according to the invention by a fastening system for a shading system for shading a building opening, such as a window or a door, with the features of claim 1. The fastening system has at least one operating profile, preferably exactly two operating profiles, namely an upper one and a lower operating profile. A respective operating profile extends along a longitudinal direction—horizontally when installed. In the installed state, the respective operating profile can be displaced in a vertical direction along tensioning cords and also has a first magnetic element. Furthermore, a slide is provided, which can be pushed into the front side of the operating profile and via which the tensioning cords are led out of the front side of the operating profile. The operating profile has such a slide on each of its end faces. Furthermore, at least one holder is provided, which is designed for mounting on a frame element of the window or the door and which is mounted on such a frame element in the mounted state. The holder has a second magnetic element.

The slider has a receptacle for at least part of the holder. The holder is at least partially and in a preferred first variant completely accommodated in this when the operating profile is in an end position, ie when the operating profile is directly adjacent to the frame element, ie in its uppermost or lowermost position. For this purpose, the slide and the operating profile are each open in the direction of the holder and thus in or counter to the vertical direction. The holder is typically designed in two parts for mounting on the frame element and has a mounting plate which is fastened to the frame element, for example by means of a screw or also by means of gluing. A so-called clamping shoe is fixed on this mounting plate, for example by sliding it on in a form-fitting manner or by snapping it on. The tensioning cord is attached to the tensioning shoe itself. Furthermore, differently designed holding elements can be provided which can be attached to the frame element and which have the mounting plate. The clamping shoe can then be fixed to this.

The two magnetic elements are also positioned in such a way that they are opposite one another when installed and when the operating profile is in the end position, so that the operating profile is held magnetically in the end position. The first magnetic element is also attached to the operating profile, independently of the slide. For this purpose, a magnet holder is provided in particular, via which the first magnet element is attached to the operating profile.

The first magnet element, optionally held in the magnet holder, is therefore designed as an independent structural unit which is attached to the operating profile independently of the slide. The attachment of the slider is therefore decoupled from a structural unit with the first magnetic element. Both the slide and the structural unit having the first magnetic element are each fastened to the operating profile and are firmly fixed in all three spatial directions.

This separate attachment has the advantage, among other things, that the assembly of the first magnet element takes place independently of the slide and, in particular, can be attached to the operating profile in advance and is also attached. As a result, simplified pre-assembly is achieved. There is also the possibility of using identical first magnet elements for different operating profiles that differ, for example, with regard to their profile cross section, specifically with different variants for the slide that is adapted to the respective profile cross section. The structural unit with the first magnetic element is therefore provided, for example, as a uniform standard component for different operating profiles, as a result of which the variety of parts is reduced. The same advantage can be achieved by choosing the slider as a standard component for different profile cross-sections and designing the magnet holder differently

According to a first preferred variant, the slide extends in the assembled state with a partial area and in particular with a part of the receptacle over the first magnetic element. It is therefore in the mounted state, when it is pushed laterally into the operating profile in the longitudinal direction, pushed over this first magnetic element. In this variant, the receptacle formed by the slide forms, in particular, an overall receptacle for (completely) receiving the holder. The receptacle has at least two or at least (preferably precisely) three side walls which form a kind of (in particular U-shaped) frame which delimits the holder in the assembled state. Due to the fact that the slide is pushed over the first magnetic element in the assembled state, a specific relative position of the two magnetic elements is ensured in the end position at the same time. Since the slide receives the holder with its receptacle, it is ensured that the two magnetic elements are arranged opposite one another in the end position.

According to a second advantageous variant, the slide is not pushed over the first magnetic element, and therefore does not extend over the first magnetic element in the mounted position in the longitudinal direction of the profile. In this variant, the mount forms only a partial mount, i.e. when assembled, the holder protrudes in the longitudinal direction of the profile over the mount of the slide. In particular, the portion of the holder that has the second magnetic element protrudes beyond the slide and its receptacle. In this embodiment variant, the receptacle preferably has only two opposite side walls.

In this second variant, the slide preferably abuts directly or alternatively, leaving a tolerance gap, on the first magnet element or on the magnet holder and thus on the structural unit which has or forms the first magnet element.

In the second variant, this structural unit, in particular the magnet holder, preferably forms a partial receptacle for the holder, which together with the receptacle for the slide forms an overall receptacle. The partial recording is therefore a continuation of the recording of the slider. It preferably also has side walls, in particular two longitudinal walls and a transverse wall connecting them, which, in the installed state, accommodate a section of the holder, specifically a section of the holder in which the second magnetic element is arranged. In particular, the side walls are flush with the side walls of the receptacle of the slide.

If the term magnetic element is used here, then this is generally understood to mean an element which is suitable for a magnetic holder. Typically, one of the two magnetic elements is designed as a permanent magnet and the other as a (magnetizable) metallic element. In principle, both magnetic elements can also be designed as permanent magnets with different polarity.

In the present case, the longitudinal direction corresponds to a slide direction of the slide, along which it is pushed into the operating profile from the front side of the latter. The vertical direction is present - based on a mounted position - defined such that it is directed from the operating profile in the direction of the holder. The longitudinal direction and the vertical direction are oriented perpendicular to one another. Furthermore, the operating profile extends in a transverse direction, which is oriented perpendicularly to the longitudinal direction and perpendicularly to the vertical direction. The three directions span a Cartesian coordinate system.

The slide generally serves to guide and deflect the tensioning cords into and out of the operating profile. The tension cords are typically deflected by 90° on the slide when exiting the operating profile.

The slider generally has a bottom. In a preferred embodiment, this has an opening in an inner partial area of the slide, with which it covers the first magnetic element in the assembled state. The opening is designed in such a way that the first magnetic element is not covered by the material of the slide. The first magnetic element is in particular freely accessible from the receptacle for the holder. The opening is generally in the form of an aperture or recess. This opening ensures that the two magnetic elements can be positioned as close as possible to one another, so that the greatest possible magnetic holding force is exerted. In general, the slider is typically a plastic component, in particular an injection-molded component.

In an expedient embodiment, the slide is designed to be stepped in the longitudinal direction, with the inner partial area at the front in the longitudinal direction and a rear, outer partial area that extends counter to the longitudinal direction to the front end of the operating profile. Viewed in the vertical direction, the outer partial area has a greater height than the inner partial area. The slider therefore has a step or shoulder overall, with only the front, inner partial area extending beyond the first magnetic element. Viewed in the longitudinal direction, the structural unit having the first magnet element therefore extends overall only over the inner partial area of the slide. In the outer partial area with the greater height, the slide is therefore made more solid, which leads to improved stability overall. The step or shoulder is positioned in such a way that the outer partial area extends to the first magnetic element in the assembled end position. In one possible embodiment, the step forms a stop to limit the position of the slide, so that the step in the installed state is in contact with the structural unit or also directly with the first magnetic element. However, the two components—namely the slide on the one hand and the magnetic element or the structural unit—are preferably not in contact with one another due to their independent attachment to the operating profile.

The receptacle for the holder defined by the slide preferably extends over both partial areas, so that together they form the receptacle for the holder.

Furthermore, it is preferably provided that the bottom of the slide in the outer partial area is aligned with the first magnetic element, that is to say is arranged at the same height as the first magnetic element when viewed in the vertical direction. Arranged at the same height is understood to mean both the exactly aligned arrangement and a tolerance deviation therefrom, for example in the range of ±1 mm-2 mm. This measure in turn ensures that the two magnet elements are positioned as close as possible to one another in the end position in the assembled state.

An end cap is typically fastened to the outside of the slide, which forms a type of screen. The front side of the operating profile is at least partially covered by this. It overhangs a profile edge so that the end cap cannot be pushed into the operating profile. By being attached to the slide, the end cap forms a stop which defines and limits the position of the slide in the longitudinal direction. The end cap therefore rests on the face of the operating profile. Furthermore, the above-mentioned step is preferably designed in such a way that there is a tolerance gap between it and the first magnetic element or the structural unit with the first magnetic element.

With regard to the best possible magnetic holding force, the two magnet elements are designed and arranged overall in such a way that they rest against one another in the end position. This means in particular that they are in direct contact with one another and no (air) gap remains between them.

In order in particular to ensure such a gap-free arrangement of the two magnet elements in the end position, at least one of the two magnet elements, preferably the second magnet element, is movably guided in the vertical direction so that it can perform an adjustment movement. The result of this is that the two magnetic elements in the end position can move towards one another in or counter to the vertical direction and thus rest against one another.

The at least one magnet element is preferably held in a form-fitting manner in a magnet holder in the vertical direction. The magnet element is preferably latched to the magnet holder. The magnetic element is in particular movably guided. The magnet holder preferably allows the adjustment movement. For this purpose, either the magnet holder itself is movably held and the magnet element is in particular arranged fixedly in the magnet holder, or alternatively the magnet element is movably held within the magnet holder.

Preferably, the second magnetic element protrudes in the direction of the operating profile and thus counter to the vertical direction over the holder, at least this applies in the end position, ie when the magnetic force is acting. In this case, the second magnetic element projects beyond an upper side of the holder by preferably 0.1 mm to 2 mm and in particular by at least 0.3 mm to 0.8 mm. According to a first off According to another variant, the second magnet element protrudes at least after the adjustment movement has been carried out, if a magnetic force acts between the two magnet elements and thus causes the adjustment movement, as it were. The second magnetic element is therefore pulled somewhat out of the holder by the magnetic force. According to a second variant, the overhang is fixed, for example by the second magnetic element being firmly fixed in the holder, for example being cast.

In a preferred embodiment, the slide has opposite lateral edges, each of which has at least one and preferably two guide webs. A respective guide web engages in the mounted position in a respective guide groove of the operating profile. In a preferred embodiment, the variant is provided with two or more guide webs on each of the edge sides. Improved guidance is achieved as a result. The several, preferably two, guide webs preferably engage in different guide grooves, and are therefore arranged at different height levels, i.e. they are arranged offset from one another in the vertical direction. The two guide webs are preferably arranged offset in the longitudinal direction. One of the guide webs is preferably arranged in the front, inner partial area and another of the guide webs on the rear, outer partial area. The arrangement of the guide web on the inner sub-area, in particular, ensures reliable and safe guidance of this sub-area, with which the first magnetic element is covered. In this way, for example, a bending of the filigree inner partial area is specifically avoided.

According to a first embodiment variant, the first magnetic element is preferably accommodated in a magnetic holder which is fastened to the operating profile. The magnet holder and the first magnet element therefore form a two-part unit that is attached to the operating profile. The first magnet element is therefore attached to the operating profile indirectly via this magnet holder. For this purpose, the first magnet element is fixed to the magnet holder, for example the magnet holder is an (injection) cast part and the first magnet element is at least partially encapsulated by the material of the magnet holder. As an alternative to this, the first magnet element is held in the magnet holder in a positive or non-positive manner.

A screw attachment or an adhesive attachment, for example, is provided for attaching the magnet holder to the operating profile. In a preferred embodiment, the magnet holder is held in a form-fitting manner on the operating profile. The operating profile regularly has a profile base, in particular an intermediate base, in which a recess, especially a punched hole, is preferably made, in which the magnet holder engages with a fastening lug in a form-fitting manner and in particular in a latching manner. This fastening lug is designed as an elastic lug so that it can snap into the recess. The operating profile preferably has further such recesses through which the tensioning cords are guided.

Like the slide, the magnet holder preferably has edge sides each with at least one guide web or guide lugs, so that the magnet holder can be pushed into a respective corresponding guide groove of the operating profile. When the recess is reached, the fastening lug automatically snaps into this recess. The fastening lug ensures positive locking in and against the longitudinal direction. In the vertical direction, it is secured via the guide bars.

In a preferred embodiment, the magnet holder is held in the mounted position within the operating profile in such a way that a free space is formed between the aforementioned profile base and the first magnet element/partial area of the magnet holder, through which the tensioning cords are passed in the mounted state. The magnet holder has an underside that is spaced from the bottom of the profile. At the same time, the fastening lug is arranged at the bottom in the direction of the profile base in such a way that when the magnet holder is pushed into the operating profile it slides along the profile base before it snaps into the recess in the profile base. The tensioning cords are therefore guided between the underside of the magnet holder and the profile base and from there into the rear, outer portion of the slide, where, for example, guide grooves for the tensioning cords are formed. The fastening lug is preferably formed in an inner partial area of the magnet holder viewed in the longitudinal direction and the first magnet element is arranged in an outer partial area. The tensioning cords are guided in particular above the fastening lug and below the first magnetic element.

As already mentioned above, the first magnet element is held in a form-fitting manner in the magnet holder in a preferred embodiment. In particular, it can be slid into the magnet holder in the longitudinal direction. For this purpose, the magnet holder has a corresponding receptacle with grooves on the edge, with the aid of which the first magnet element is guided. The first magnet element and/or the magnet holder preferably has (lateral) latching contours, so that a latching connection is formed between the magnet element and magnet holder. Special lateral latching lugs are formed on the magnet element, each of which engages in a corresponding bulge within the magnet holder.

According to a second variant, the first magnetic element is part of a one-piece, monolithic structural unit and is fastened with it almost directly to the operating profile, ie without an additional component such as the magnetic holder described. For this purpose, the monolithic structural unit is designed in particular as a (sheet metal) bent part. The monolithic structural unit has a base plate and a fastening lug bent downwards from the base plate in the direction of the profile bottom for engagement in the recess. Furthermore, the bending part has at least one tab that is bent up at the side and has a bulge at the edge, which forms a guide bar for engaging in a respective guide groove of the operating profile. Furthermore, the bending part has a lug which is bent over from the base plate, in particular by 180°, and which forms the first magnet element. This is formed by a plate-shaped portion of the bent part.

Similar to the magnet holder, the first magnet element and the fastening lug are arranged at two different levels and the first magnet element is arranged at a distance from the profile base, so that the free space for guiding the tensioning cords described above in connection with the magnet holder is formed.

In the figures, parts that have the same function are provided with the same reference numbers.

According to 1 a window 20 has a shading system 22 that includes a fastening system with a hanging 24 . The curtain 24 is designed as a pleated fabric. The hanging 24 is clamped between two operating profiles 26 . The operating profiles 26 can be moved along tension cords 28 and positioned at any position. The tensioning cords 28 are fastened to a respective frame element 32 of the window 20 by means of holders 30 . A total of four holders 30 are fixed in the four corners of the frame of the window 20 . From each holder 30, the tensioning cords 28 run vertically along the frame, are inserted into the operating profile 26 at the front, run in this in the transverse direction and emerge from a bottom of the operating profile, are threaded vertically through the curtain 24 before they are passed through a Enter the bottom of the opposite operating profile 26. In this they are again guided laterally to the end face, come out of this and are guided to the opposite holder 30 . The position shown in the figure shows an intermediate position, in which the two operating profiles 26 are spaced apart from the frame and thus from the holders 30 .

In a respective end position of a respective operating profile 26, this is pulled towards the frame, typically so far that the Operating profile 26 with an open, frame-oriented profile side covers the holder 30 and rests directly on the frame in order to ensure gap-free shading. The respective holder 30 is therefore accommodated in the operating profile 26 in such an end position.

One or both of the operating profiles 26 are preferably held in this end position on the holders 30 by magnetic force, as will be explained in more detail in connection with the following figures.

The operating profile 26 generally extends, starting from its front end, in a longitudinal direction L. It also extends in a vertical direction V, which is defined perpendicularly to the longitudinal direction L and in the direction of the holder 30 . Finally, the operating profile 26 extends in a transverse direction which, together with the longitudinal direction L and the vertical direction V, spans a Cartesian coordinate system.

How based on 2A , 2 B can be seen, at a respective front end of a respective operating profile 26 in the installed end position is a magnet holder 34 with a first magnet element 36, in particular a simple metal plate, a slide 38 with a front end cap 40, and the holder 30 with a second magnet element 42 arranged. The holder 30 includes a mounting plate 44 which is fastened to the frame element 32, for example by means of a screw. Furthermore, the holder 30 in the exemplary embodiment has a cap, typically made of plastic, which is also referred to as a clamping shoe 46 . This can be slid onto the mounting plate 44 from the side and secured with it in a form-fitting manner. The second magnet element 42 is accommodated in the clamping shoe 46 .

The slider 38 has a receptacle 48 in which the holder 30 is received in the end position. All characters except for 8th show a first variant of the slide 38, in which the receptacle 48 extends over the first magnetic element 26 in the assembled state and in this respect forms an overall receptacle for the holder 30. The receptacle 48 is open towards the end face and towards the frame element 32 . The end cap 40 is fastened to the slide 38 on the end face, for example latched or pushed on in a form-fitting manner. The end cap 40 rests against the front edge of the operating profile 26 and, in particular, defines a longitudinal stop when the slide 38 is pushed in.

The tension cords 28 are guided within the operating profile 26 along a profile base 50, which is designed as an intermediate base. They are guided in a free space which is formed between an underside of the magnet holder 34 and the slide 38 and the profile base 50 . The tension cords 28 are led out at the front and are deflected by 90° on the front end side of the slide 38 and guided into the holder 30, where one end of the tension cords 28 is fixed in a suitable manner. At the front end of the slide 38 a guide groove for the tensioning cords is in particular formed. This is preferably covered by the end cap 40 so that the tensioning cords 28 are guided between the end cap 40 and the end face of the slide 38 .

As in particular from the 2 B it can be seen that the two magnet elements 36,42 lie directly against one another. This ensures a high magnetic holding power.

The slide 38 generally has a base 52 which has an opening 54 in a front partial area which covers the first magnetic element 36 so that this is thus more or less freely accessible.

As in particular from the 3 and the 4C As can be seen, the slider generally has a front, inner portion 56 and a rear, outer portion 58 . The inner portion 56 has the opening 54 . Both sections 56, 58 together form the receptacle 48 in which the holder 30 is received. The two partial areas 56 , 58 together form a receiving area formed by U-shaped boundary walls, which is limited downwards only in the outer partial area 58 by the base 52 . In the area of this floor 52 and thus in the outer sub-area 58, the slide has a greater height in the vertical direction V, ie the floor 52 is in particular made with a greater material thickness, so that a step is formed in the transition area between the two sub-areas 56,58.

In the assembled position, the first magnetic element 36 is preferably aligned with an upper side of the base 52, which is oriented towards the holder 30. The first magnetic element 36 therefore forms a kind of continuation of the base 52 in the region of the opening 54.

The slider 38 covers the magnet holder 34 only with its inner portion 56. The step formed in the transition to the outer portion 58 preferably has a gap thereto.

The magnet holder 34 as well as the slider 38 and the clamping shoe 46 are preferably injection molded parts made of plastic.

How special from the 4A , 4B can be seen, the first magnet element 36 is held in a form-fitting manner and in particular in a latching manner on the magnet holder 34 . For this purpose, it has at least opposite peripheral grooves into which the first magnetic element 36 can be pushed in the longitudinal direction L. This has latching lugs 59 on the edge, with which it engages in corresponding latching receptacles in the grooves of the magnet holder 34 and is thus held on it in a form-fitting manner.

In the area of the first magnet element 36, the magnet holder 34 has an underside which, in the assembled position, is at a distance from the profile base 50 and defines the free space there for the tensioning cords 28 to pass through. In the longitudinal direction L following this (outer) partial area in which the first magnet element 36 is held, a fastening lug 60 is formed in an inner partial area of the magnet holder 34 , which is preferably formed on a lateral edge web of the magnet holder 34 . For this purpose, an approximately L-shaped inwardly bent tab is formed on this edge web, which is preferably only continued on one side in the longitudinal direction L from the outer partial area, on which the fastening lug 60 is formed protruding downwards towards the profile base 50 . The fastening lug 60 is held elastic overall. It extends counter to the vertical direction V and, in the installed state, engages in a recess 62 in the profile base 50 . The tensioning cords 28 are guided above this L-shaped angled bracket. This is therefore at a lower level than the first magnet element 36 and the underside of the magnet holder 34 formed in this outer partial area.

The magnet holder 34 also has guide webs 68A on its edge sides, with which it is pushed into corresponding guide grooves 66 of the respective operating profile 26 .

In the exemplary embodiment, the magnet holder 34 has an open end face on the back, so that the first magnet element 36 is exposed on this open end face. During assembly, the magnet holder 34 is pushed into the operating profile 26 in the longitudinal direction L. As soon as the fastening lug 60 reaches the recess 62, it snaps in and secures the magnet holder 34 on the operating profile 26 in and counter to the longitudinal direction L. Securing in the vertical direction V takes place via the guide webs 68A.

Like in particular 4C it can be seen that the slide 38 has two guide webs 68B attached to its two edge sides, which are arranged offset to one another both in the longitudinal direction L and in the vertical direction V. They engage in different guide grooves 66 . The front guide webs 68B are formed on the inner partial area 56 and guide it reliably.

As an alternative to the latching attachment of the magnet holder 34, it can also be attached via a screw attachment, as is shown in FIG 5 is shown.

As an alternative to the indirect attachment of the first magnet element 36 via an additional component formed by the magnet holder 34, the first magnet element 36 is part of a monolithic bent part 70, as is shown in FIGS 6A , 6B is shown. This has a base plate 72, from which an elastic fastening lug 60 is bent downwards, which in turn engages in a latching manner in the recess 62 described. A bent-up tab 74 is formed at the edge, which has a bulge at the edge, which forms a guide web 68B. With this, the bending part 70 engages in a corresponding guide groove, in particular in a latching manner 66 . Finally, the bending part 70 has a tab bent by 180°, which forms the first magnet element 36 .

In both design variants, that is to say with a magnet holder 34 or with the bending part 70, the first magnet element 36 is part of a structural unit which is fastened to the operating profile 26 in all three spatial directions.

The first magnetic element 36 is preferably formed by a simple metal element, specifically a simple metal plate, which is preferably only magnetizable, but not a permanent magnet. Conversely, in a preferred embodiment, the second magnetic element 42 is designed as a permanent magnet. In principle, the reverse configuration is also possible. As a further alternative, the first and second magnetic elements can be designed as permanent magnets, which attract one another.

Based on 7A , 7B the attachment of the second magnetic element 42 to the clamping shoe 46 is shown. The second magnetic element 42 is attached in an end region of the clamping shoe 46 viewed in the longitudinal direction L and penetrates a floor so that it is freely accessible from the outside. It is preferably held in a form-fitting manner and in particular via a snap-in connection. In particular, it is kept movable, as indicated by the arrow in 7B is shown. It is therefore held in a type of guide so that it can perform a compensatory or adjustment movement in or counter to the vertical direction V. This ensures in particular that in the end position, as in the 2A , 2 B is shown, the second magnetic element 42 is quasi pulled out by the magnetic holding force, so that on the one hand it protrudes over the clamping shoe 46 and on the other hand comes into direct contact with the first magnetic element 36 . The sliding bearing that is present in this respect allows, for example, a movement in the range between 0.1 mm and 2 mm and in particular in the range between 0.3 mm and 0.8 mm.

As an alternative to this movable fixing, the second magnetic element 42 can also be immovably fixed. For example, it is cast in the material of the clamping shoe 46 . In the same way, the first magnet element 36 can also be cast in the material of the magnet holder 34 . This means that the respective magnet element 36, 42 is at least partially encapsulated in the plastic melt when the magnet holder 34 or the clamping shoe 46 is produced.

The clamping shoe 46 generally also forms a magnet holder since it holds the second magnet element 42 . The tension cord 46 can therefore also be referred to as a second magnet holder, and the magnet holder 34 as the first magnet holder.

8th 12 shows a second variant of the slide 38. In this case, the receptacle 48 forms only part of an overall receptacle for the holder 30. In this embodiment variant, the slide 38 does not extend over the first magnet element 36 in the longitudinal direction L. The slide 38 ends at the magnet holder 34 and abuts directly against it, for example butt-jointly. Alternatively, a tolerance gap is formed.

The magnet holder 34 preferably also forms a partial receptacle 76 which, together with the receptacle 48, forms the overall receptacle for the holder 30. Compared to the example in the 3 The configuration shown, therefore, the magnet holder 34 also has side walls on its upper side, namely two longitudinal walls and one transverse wall. Otherwise, the magnet holder 34 corresponds to the configuration according to FIG 3 .

The slider 38 is compared to 3 modified only in such a way that the front portion of the slide 38 with the opening 54 in the longitudinal direction L is omitted. The rest of the end cap 40 oriented portion of the slider 38 according to 3 corresponds to the slider 38 as shown in 8th is shown. A (central) channel for the tensioning cords 28 is therefore formed on one end face in the bottom area, and the end cap 40 is also fastened to this end face in the assembled state. Compared to that 3 are therefore the side wall areas that the portion of the receptacle 48 in the 3 form, which border the bottom opening 54, now formed on the magnet holder 34.

The invention is not limited to the exemplary embodiments described above. On the contrary, other variants of the invention can also be derived from this by a person skilled in the art without departing from the subject matter of the invention. In particular, all of the individual features described in connection with the exemplary embodiment can also be combined with one another in other ways without departing from the subject matter of the invention.
