Abstract

A screen system (10) is described for a retractable screen (20). The screen system (10) contains two elongated side guides (200) containing a screen profile (300), a one-piece removable profile (400) and a one-piece mounting profile (500). The screen system also contains a retracting device (100) which is removablely mounted at the top of the two side guides (200) by means of fastening elements (120). At the level of the two side guides (200) a removable locking element (130) is fitted which can only be removed when the removable profile (400) has been removed from the corresponding side guide (200).

Description

2 Once the first part of the screen guide is installed, the orientation of the second part is fixed. Therefore, great care must be taken to correctly install the first part of the screen guides of the screen system in relation to the plane of the window, the door, etc., where they are installed.

[006] Additionally, it is advantageous when the screen system allows the screen to be removed from the system in the direction of the screen guides. This is particularly advantageous when, for example, the screen winding device is installed in such a way that this is the only direction that allows the rolled-up screen to be removed, such as when the winding device is mounted in a cavity or behind another permanent structure of the building near an opening for a door, a window, etc.

[007] Furthermore, the winding device is also exposed to these forces acting on the screen, so there is a need for a winding device whose screen winding shaft can be mounted and dismounted in a simple and efficient manner, and where suchloads can be withstood in a robust and reliable manner.

[008] There is therefore a need for a screen configuration that can withstand the aforementioned disadvantages15 and at the same time offers greater flexibility, is easier to disassemble and disassemble, can withstand a greater load, and / or can withstand a load in a more reliable manner. Summary20

[009] According to the first phase, provision is made for a screen device for a screen that can be rolled up and down in a longitudinal direction, which contains a corresponding thickening along two sides opposite in the transverse direction, the screen device containing the two elongated side guides fitted to guide the screen and hold it to the corresponding thickening of the two opposite sides of the screen, where each of the two side guides contains: -a screen profile configured for -guiding the thickening during rolling up and down in the longitudinal direction; and -enclosing the thickening to hold the thickening in the screen profile;30-a one-piece removable profile configured for surrounding the screen profile to keep the screen profile within the removable profile; and BE2025 / 5031 3 -a one-piece mounting profile configured for the removable mounting of the removable profile, CHARACTERIZED BY THE FACT THAT -the screen device further contains a winding device for winding the screen onto a winding shaft, whereby the winding device is removablely mounted at the top of the two side guides by means of fastening elements; -the winding device contains at least at the height of the two side guides a removable locking element configured to prevent the winding shaft from being removed from the winding device when applied; and -the locking element is configured so that it can only be removed when the removable profile of the corresponding side guide is removed.

[010] In this way, a screen configuration is realized whereby the winding shaft can be installed efficiently and reliably in the winding device. Furthermore, the safeguarding element ensuresthat cannot be removed in the secured state of the side guide before the screen device can withstand a greater load and can withstand a load in a more reliable manner with a reduced risk that the winding shaft would come out of the winding device unintentionally.

[011] According to a design, a screen device is provided in which the locking elements are configured to be removablely attached to the housing of the winding device by means of a click connection.

[012] According to a design, a screen device is provided in which the locking elements contain one or more upward protrusions to achieve the locking, which prevent movement of the fastening element in the transverse direction for the removal of the winding shaft from the winding device.

[013] According to a design, a screen device is provided, whereby the 25 winding device contains a cover plate for the underside of the housing of the winding device which is configured to be removablely attached to the securing elements of thescreen device.

[014] According to a design, a screen device is provided in which: -the cover plate is configured to be removablely attached to the locking elements by means of a click connection; and / or BE2025 / 5031 4 -the cover plate in the attached state rests against a stop surface of the locking elements for positioning the cover plate.

[015] According to a design, a screen device is provided in which the cover plate is configured so that: -the cover plates can only be removed when the removable profile of the corresponding side guide has been removed; and / or -it is prevented that the winding shafts and / or the locking elements can be removed from the winding device when the cover plate is installed.

[016] According to a design form, a screen device is provided in which the locking elements contain at least one stop surface for a bottom bar fitted at the bottom of the screen.

[017] According to a design form, a screen device is provided in which theThe winding device is attached to the winding device in such a way that the winding shaft is only removable from the winding device via the side guides.

[018] According to a design form, a screen device is provided, whereby the screen device contains a foot consisting of a selection of one or more connectable feet from the following combination: - an inclined foot; and / or - a foot without incline.

[019] According to a second aspect, a method is provided for mounting or dismounting a screen device according to the first aspect, whereby the method contains the following steps: - the removable mounting of the winding device at the top of the two side guides by means of the fastening elements; and - the application or removal of the locking element when the removable profile of the corresponding side guide has been removed.

[020] According to an execution form, a method is provided, whereby the method contains the following step: -attaching or removing the cover plate to the retaining elements when the removable profile of the corresponding side guide has been removed. 30

[021] According to an execution form, a method is provided, whereby the method contains the following steps: BE2025 / 5031 5 - attaching the winding device to a building so that the winding shaft is only removable from the winding device via the side guides.

[022] In accordance with the following aspect, provision is made for a screen device that can be rolled up and down in a longitudinal direction, containing a corresponding thickening along two sides opposite in the transverse direction, the screen device containing the two elongated side guides fitted to guide the screen and to hold it to the corresponding thickening of the two opposite sides of the screen, where each of the two side guides contains: -a screen profile configured for -guiding the thickening during rolling up and down in the longitudinal direction; and -enclosing the thickening to keep the thickening in the screen profile; -a one-piece removable profile configured for enclosing the screen profile to keep the screen profile in the removable profile; and-a single-piece mounting profile configured for the removable mounting of the removable profile, characterized BY THE FACT THAT: -the removable profile and the mounting profile form a first coupling and a second coupling which, in a mounted state, are located on either side of the screen plane, and which are configured to move between a mounted state and a removable state by means of mutual movement perpendicular to the screen plane; -the removable profile and the mounting profile form a locking mechanism, in which, in the mounted state, a locking element can be removablely installed to prevent mutual movement perpendicular to the screen plane; and -in the mounted state, in a direction perpendicular to the screen plane, the first coupling and the second coupling are located on the same side with respect to the locking mechanism.

[023] In this way, a screen configuration is realized with a minimum number of parts, which offers the flexibility of removing the removable profile even when itscreen profile was installed at a location where only the screen-facing side of the screen profile is accessible. In addition, the couplings further facilitate assembly and disassembly, since the transverse movement of the removable profile relative to the fixing profile is sufficient to move between a fixed state and a BE2025 / 5031 6 removable state of the removable profile. Moreover, the specific location of the couplings ensures that they are installed close to and on both sides of the screen surface, allowing them to withstand a greater load and cope with a load in a more reliable manner. Furthermore, the retaining element is at least partially shielded from the greatest load exerted on the side guide by the screen.

[024] According to an execution form, a screen arrangement is provided, whereby: -the first link contains: -a first link section of the removable profile is attached; and-a second coupling part is attached to the mounting profile, whereby the first coupling part and the second coupling part are configured to move between the fixed state and the removable state by means of mutual movement perpendicular to the plane of the screen; and -the second coupling contains: -a first coupling part is attached to the removable profile; and -a second coupling part is attached to the mounting profile, whereby the first coupling part and the second coupling part are configured to move between the fixed state and the removable state by means of mutual movement perpendicular to the plane of the screen.

[025] In this way the coupling can be realized simply and reliably.20

[026] According to a design, a screen arrangement is provided in which: -the removable profile contains a U-shaped part for surrounding the screen profile where the U-shaped part contains: -a bottom perpendicular to the plane of the screen; -two legs extending from the bottom along and on either side of the plane25 of the screen; and-two mutually oriented spans that partially span from the corresponding end of the two legs and the opening between the two legs; -the fastening profile contains: -a base perpendicular to the plane of the screen; and30 -at least one leg extending from the base along the plane of the screen; -the first coupling contains: BE2025 / 5031 7 -a first coupling part which contains or consists of a projection that extends in one direction away from the plane of the screen from a first leg of the U-shaped part of the removable profile; and -a second coupling part which contains or consists of a projection that extends in one direction towards the plane of the screen from a first leg of the fastening profile, whereby in the fixed state the first coupling part leans against the second coupling part and is located between the second coupling part and the base of the fastening profile; -the second coupling contains: -the first coupling part that contains or consists of a hook-shaped element that is attached to the U-shaped part of the removable profile and that contains an end that is in a direction 10is directed towards the plane of the screen; and -a second coupling part which contains or consists of a hook-shaped element which is attached to the bottom of the mounting profile and which contains an end which is directed away from the plane of the screen, whereby in the mounted state the projection of the first coupling part leans against the projection of the second coupling part and is located between the second coupling part and the bottom of the mounting profile.

[027] This allows the couplings to be realized with simple and reliable elements.

[028] According to a design form, a screen arrangement is provided in which: -the mounting profile contains a U-shaped part, where the U-shaped part contains: -a bottom perpendicular to the plane of the screen;20 -two parallel legs extending from the bottom along and on either side of the plane of the screen.

[029] This offers the advantage that the mounting profile can easily be attached to a building in different orientations.

[030] According to a design, a screen device is provided, whereby the25removable profile is configured to be applied to the mounting profile in two different orientations.

[031] In this way, a screen installation with great flexibility is realized, whereby different desired configurations of the screen profile can be realized with a minimum of profiles. This also ensures that efficient and robust mounting is possible, in particular when, for example, a mounting profile has been installed in a hard-to-reach location or in a way that does not allow removal without damage, such as, for example, at least partially embedding it in the plastering of the mounting profile. Regardless of the orientation of the mounting profile, under similar conditions the removable profile can be installed in the desired orientation.

[032] According to an execution form, a screen device is provided, whereby: -the first link in a first orientation of the removable profile contains:5 -a first link section of the removable profile is attached; and-a second coupling part is attached to the mounting profile, whereby the first coupling part and the second coupling part are configured to move between the attached state and the removable state by means of mutual movement perpendicular to the plane of the screen; and10 -the first coupling in a second orientation of the removable profile contains: -a first coupling part is attached to the removable profile; and -a third coupling part is attached to the mounting profile, whereby the first coupling part and the second coupling part are configured to move between the attached state and the15 removable state by means of mutual movement perpendicular to the plane of the screen; and -the second coupling in the first orientation of the removable profile contains: -a first coupling part is attached to the removable profile; and -a second coupling part is attached to the mounting profile, whereby the first coupling part and the second coupling part are configured to by means20by means of mutual movement perpendicular to the plane of the screen between the fixed state and the removable state; and -the second coupling in the second orientation of the removable profile contains: -a first coupling part attached to the removable profile; and -a third coupling part attached to the fixing profile,25 whereby the first coupling part and the third coupling part are configured to move perpendicular to the plane of the screen between the fixed state and the removable state.

[033] In this way, the selective installation of the removable profile can be easily realized.30

[034] According to a design, a screen device is provided in which, BE2025 / 5031 9 with respect to a plane centrally located between both legs of the fastening profile, the distance of the second coupling part and the third coupling part of the first couplings and / or the distance of the second coupling part and the third coupling part of the second coupling: - are equal or nearly equal; - contain a percentage difference of 10% or less;5-contain a percentage difference of 5% or less.

[035] This allows the coupling parts of the mounting profile for the selective fastening of the removable profile to be realized in a simple manner, which also makes it easy for an installer to carry out the fastening in both orientations since the symmetrically arranged coupling parts allow for similar fastening in both orientations.10

[036] According to a design form, a screen device is provided in which: -the screen device further contains a winding device for winding the screen onto a winding shaft, where the winding device is removablely mounted at the top of the two side guides by means of fastening elements; -the winding device contains, at least at the height of the two side guides, a removable locking element15 that is configured to prevent the winding shaft from being removed from the winding device; and -the locking element is configured so that it can only be removed when the removable profile of the corresponding side guide is removed.

[037] In this way, the roller shaft and optionally a screen rolled up onto it can be installed in an efficient and simple manner in the roller device after the side guides have already been installed under the roller device, without creating the risk that, in the fixed state of the side guides, where the removable profile has also been installed, the roller shaft can come loose from the roller device in an undesirable manner.

[038] According to a design, a screen device is provided in which the roller device is installed and built in such a way that the roller shaft is only removable from the roller device via the side guides.

[039] This is particularly advantageous when it is desired to install, for example, the roller device in a wall cavity, or in or behind a permanent structure of a building, such as a plaster layer, where only the underside of the roller device is accessible30 for installing and / or removing the roller shaft for the screen. BE2025 / 5031 10

[040] According to a subsequent aspect, a method is provided for mounting ordismantling a screen device in accordance with the previous aspect, whereby the method contains the following step: -moving the removable profile and the fastening profile between a fixed state and a removable state by means of mutual movement across the plane of the screen.

[041] This allows for efficient, robust and simple assembly and disassembly of the screen device, even when the fastening profile is permanently or in a difficult-to-remove location on a building or structure.

[042] According to an execution form, a method is provided whereby the method further contains the following step: -in the fixed state, the removable installation of a locking element in the locking mechanism to prevent mutual movement across the plane of the screen.

[043] This ensures that the securing elements are optimally shielded by the couplings and preloads on the side guides generated by the screen.15

[044] According to an implementation form, a method is provided, whereby the method further contains the following step:-selectively attaching the removable profile to the mounting profile in one of two different orientations.

[045] In this way, an efficient and robust mounting of the side guide can be achieved20 whereby the desired orientation of the removable profile can be achieved after attaching the mounting profile.

[046] According to an execution form, a method is provided, whereby the method contains the following steps: -attaching the removable profile in a first orientation by:25 -forming the first coupling with the first coupling part and the second coupling part of the first coupling; and -forming the second coupling with the first coupling part and the second coupling part of the second coupling; - arranging the removable profile in a second orientation by: 30 - forming the first coupling with the first coupling part and the third coupling part of the first coupling; and BE2025 / 5031 11 - forming the second coupling with the first coupling part and the third coupling part of the second coupling;

[047] This allows the removable profile to be installed efficiently and reliably in the desired orientation in a simple manner.

[048] According to a design, a method is provided in which the method contains the following 5 steps:

[049] -the removable installation of the winding device at the top of the two side guides by means of the fastening elements; -the installation or removal of the locking element when the removable profile has been removed from the corresponding side guide.10

[050] This method ensures efficient mounting and dismounting of the winding shaft without the risk of the winding shaft coming loose when the removable profile is mounted in the fixed state on the fastening profile of the side guide.

[051] According to an execution form, a method is provided, whereby the method contains the following steps:15 -attaching the winding device to a building so that the winding shaft is only removable from the winding device via the side guides.

[052] The method is particularly advantageous in similar circumstances where the winding shaft is onlythis method can be attached to or removed from the rolling device.

[053] It is clear that the forms of execution described above constitute optional and / or preferred forms of execution and that many other variants and combinations are possible without deviating from the scope of protection as defined in the claim. In particular, forms of execution of an aspect are possible which contain one or more characteristics, as well as variants and / or combinations of similar characteristics of one or more forms of execution of another aspect.25 Brief Figure description

Detailed description25

[055] Figure 1 shows a schematic and perspective view of the design of a screen device10. A design of a screen20 suitable for use in a screen device10 of Figure 1 is schematically shown in Figure 2. In the state shown in Figure 1, the screen20 is in a rolled-up state in the rolling device100.30 As known to a professional, such a screen20 can be rolled up and down in accordance with a BE2025 / 5031 13 longitudinal direction L as indicated in Figure 1. Figure 2 shows a view in this longitudinal direction L of the design of the screen20.

[056] As visible in Figure 2, the design of the screen20 contains along two,according to a transverse direction D opposite sides 22,24 corresponding thickening 26,28. It is clear that the transverse direction D is transverse to the longitudinal direction L, and that the transverse direction 5 and the longitudinal direction L form the plane V of the screen, or in other words, the plane V in which the screen 20 is in the unrolled state. It is clear that variant forms of execution are possible for the shown thickening 26,28 on each of the opposite sides 22,24, also known as lateral sides, of the screen 20. The thickening can, for example, contain or consist of half of a zipper or other suitable thickening applied to or on the screen 10 along the sides 22,24. It is further clear that this thickening 26,28 extends along the respective 22,24 in the unrolled state of the screen in accordance with the longitudinal direction L. 20. In this regard, according to certain designs, the thickening may extend over the entire length of the screen20; however, alternative designs are possible where the thickening is onlyapplied to a part of the length of the screen and / or according to a specific pattern, 15 for example a repetitive pattern along the longitudinal direction is applied to the screen.

[057] The design of the screen device10 contains two elongated side guides200, of which only 1 is shown in Figure 1 for clarity. installed to guide the screen20 and to keep it at the corresponding thickening26,28 of the two opposite sides22,24 of the screen20. In other words, as known to the 20 craftsman, a side guide200 is installed on each side22,24 of the screen20. In other words, along the transverse direction. On both sides of the screen20 these side guides 200 are installed. The side guides 200 are elongated elements, also known as profiles, which extend elongated along the longitudinal direction.

[058] The design of the side guides200 as shown in Figure 1 is explained in more detail using Figures 3 to 5, which show a cross-section of theside guide 200, in other words following a plane perpendicular to the longitudinal direction L. As visible in Figure 1, the side guide 200 also extends along a width direction B, perpendicular to the plane V of the screen 20, or in other words perpendicular to the longitudinal direction transverse direction D.

[059] Figures 3 to 5 show different steps of a method for assembling the 30 version of the side guide 200. Figure 5 shows the assembled state of the side guide 200 version, and Figures 3 and 4 show two steps for the disassembly BE2025 / 5031 14 or assembly of this side guide 200. It is clear that a version of a method for disassembling the side guide 200 version is also represented when, starting from the assembled state in Figure 5 via the state in Figure 4, the disassembled state in Figure 3 is reached. As visible in Figure 3, the side guide 200 contains a version of a screen profile 300. Such a screen profile 300 is 5 configured to guide the thickening 26 during rolling up and down according to thelongitudinal direction L. As further visible, such a screen profile 300 is also configured to surround the thickening 26 of the screen 20 in order to keep the thickening 26 within the screen profile 300. As visible and as known to a professional, this can be realized, for example, by a design in which the screen profile 300 incorporates the thickening 26 into an elongated slot 310 with an opening for the screen 20 that is smaller than the thickening 26, so that the thickening 26 cannot leave the slot through the opening in the slot 310. As further visible, the design of the screen profile 300 can contain a base 320 to which the slot 310 is attached, as well as elastic elements 330 that are placed between the base 320 and a removable profile 400, for example to keep the screen 20 under tension. Such 15 elastic elements may contain or consist of one or more suitable springs, or one or more elements of different elastic or resilient material such as, for example, rubber,….

[060] It is clear that the screen profile 300 is an elongated profile that extendsalong the longitudinal direction L. When unrolling and rolling up the screen20, the bottom of the screen20 therefore typically moves downwards or back up to this top side from the top of this screen profile300. In doing so, the thickening26 of the screen20 slides through the screen profile300. It is further clear that this takes place on both sides of the screen20 along the transverse direction D, in other words at the screen profiles300 of both side guides 200 located on both sides of the screen20. In other words, by means of the screen profiles300, the screen20 is guided between the side profiles200 along the longitudinal direction25 and held along the transverse direction D.

[061] It is clear that many variant designs are possible, other than the design of the screen profile300 as shown in Figure 3. For example, variations are possible regarding the shapes and dimensions of the slot310 and the base320, and designs are possible in which, instead of and / or in addition to elastic elements330, for example, tension elements are present30such as, for example, mechanical, magnetic, ... tensioning elements that can appropriately bring and / or keep the screen BE2025 / 5031 15 20 under tension. The screen profile 300 can be manufactured from a suitable metal or plastic, preferably with a material with a low coefficient of friction.

[062] Furthermore, the design of the screen guide 200 shown in Figure 3 contains a one-piece removable profile 400 and a one-piece fixing profile 500. This removable profile 400 is, as visible, configured for surrounding the screen profile 300 in order to hold the screen profile in the removable profile 400. The one-piece fixing profile 500 is, as visible, configured for the removable fixing of the removable profile 400. It is furthermore clear that the removable profile 400 and the fastening profile 500 are also elongated profiles that extend along the longitudinal direction L. Preferably, these profiles are extruded profiles made of a suitable metal such as, for example, aluminium, however the 10It is clear that alternative designs are possible whereby the profiles are manufactured from any suitable metal or plastic.

[063] As visible in Figures 3 to 5, the removable profile 400 and the mounting profile 500 form a first coupling 600 and a second coupling 700. Figure 5 shows this first coupling 600 and second coupling 700 in a fixed state. As visible in Figure 15, in this fixed state, the first coupling 600 and the second coupling 700 are located on either side of the plane V of the screen 20. As further visible, the first coupling 600 and the second coupling 700 are further configured to move by means of a mutual movement perpendicular to the plane V of the screen 20 between a fixed state as shown in Figure 5 and a removable state as shown in Figure 4. In other words, a movement along the width direction B, in the orientation shown in Figure 5 to left, of the removable profile400 relative to the fixing profile500, the movesfirst coupling600 and second coupling700 from the confirmed state shown in Figure 5 to the removable state shown in Figure 4. It is clear that in the confirmed state shown in Figure 5, the removable profile400 is removablely attached to the 25 fixing profile500. It is furthermore also clear that in the removable state shown in Figure 4, the removable profile400 can be removed from the fixing profile500, in particular by means of a movement along or nearly along the transverse direction D, in order to reach the removed state shown in Figure 3. Conversely, it is also clear that the removable profile400 can be inserted into the fixing profile500, in particular by means of a movement along or nearly along the transverse direction D, in order to reach the removable state shown in Figure 4 from the removed state shown in Figure 3 to the removable state shown in Figure 4 BE2025 / 5031 16 reach. Subsequently, for example, from the removable state of Figure 4, thethe confirmed state shown in Figure 5 can be achieved by a movement along the width direction B, in the orientation shown in Figure 5 to the right.

[064] As further visible in Figure 5, the removable profile 400 and the fixing profile 500 contain and form a locking element 800. In this locking element 800, as shown in Figure 5, a removable locking element 900 can be installed in the confirmed state. It is clear that this locking element 900 installed in the locking element 800 prevents mutual movement in the confirmed state perpendicular to the plane V of the screen 20, or in other words along the width direction B.

[065] According to the design shown, the locking element 900 is designed as a bolt 10 900. However, it is clear that alternative designs are possible, such as a screw, a pin, a snap-on element, a clamping element, etc., which can be attached in a removable manner in the locking element 800 in the attached state.

[066] According to the design shown, the locking element 800 contains a first locking part 810and a second locking part 820. It is clear that the removable profile 400 contains the first locking part 810 and that the fastening profile 500 contains the second locking part 820. The design of the first locking part 810 contains, as shown, a part of the removable profile 400 with a surface configured to attach the removable locking element 900. For the shown design example, these are profiled surfaces onto which the thread of the bolt 900 can engage. However, it is clear that 20 alternative design forms are possible, whereby alternative surfaces are possible for use with alternative locking elements.

[067] As shown in Figure 3, in the removed state, the locking element 900 can already be installed in the first locking part 810. According to the execution example shown, this means that the bolt 900 is partially screwed into the first locking part 810. At the 25 removable position of Figure 4, this is also the case. As shown in Figure 4, it issecond locking part 820 preferably configured such that in this removable state, the bolt 900 is prevented from reaching far enough out of the removable part 400 to prevent displacement along the width direction B towards the fixed position in Figure 5. As visible, in this removable state of Figure 4, the second locking part 820 functions as a stop for the bolt 900, so that further displacement of the outer end of the bolt 900 in the direction of the fixing profile 500 is prevented. This allows displacement along the width direction B between the removable state in Figure 4 and the fixed state in Figure 5 to remain possible. As shown in Figure 5, the first locking part 810 and the second locking part 820 aligned with each other so that the bolt 900 can be screwed further into the second locking part 820.

[068] As shown in Figure 6, one version of the screen device 10 may have several such locking elements 900 which are at different places along the side guide 200installed to secure the couplings700,800of the side guide200 in the secured state. As visible in Figure 6, three such securing elements900 are installed. However, it is clear that alternative designs are possible whereby any other suitable number of securing elements900 is used per side guide200, such as, for example, one, two, three, four, five, or any other suitable multiple of securing elements900.

[069] As shown in Figure 5, it is also clear that according to the shown design, in the mounted state, in a direction perpendicular to the plane V of the screen 20, or in other words in the width direction B, the first coupling 600 and the second coupling 700 are located on the same side with respect to the retaining 800. Or in other words, the retaining 800 is not located between the first coupling 600 and the second coupling 700 in the width direction B. This is advantageous since the couplings 600, 700 absorb, or largely absorb, the forces exerted by the removable profile 400 on the mounting profile.500 are exerted under the influence of tension or load on the screen20, or in other words forces, according to, or largely according to, the direction of the plane V of the screen20. In this way, the 20 securing element 900 in the securing 800 must not or virtually not be responsible for absorbing forces in this direction, and provides only or primarily a securing function to prevent displacement along the width direction B of the removable profile 400 relative to the fixing profile 500.

[070] This offers the advantage that inserting the locking element900 into the locking element800 in the 25 confirmed condition is less critical. Even if this connection were to degrade in the long term, or if the insertion of the locking element900 during assembly is not carried out sufficiently consistently, there will still be a secure connection by means of the couplings 600, 700 between the removable profile 400 and the fixing profile 500 which the loads generated by the screen 20, the largest component of which extends along the plane V of the screen 20, at 30can absorb in a reliable manner. Moreover, the safeguard 800 and the safeguard element 900 are at least partially shielded by the nearest coupling 700 from forces BE2025 / 5031 18 generated by the screen 20 acting on the side guide 200, since this coupling 700 is located between the safeguards and the plane V of the screen 20 in the width direction B.

[071] The design shown in Figure 1 to Figure 5 shows a removable profile 400 containing a U-shaped part. It is clear that this U-shaped part surrounds the screen profile 300. Or in other words, that the screen 20 on the lateral side 22, 24 can enter the removable profile 400 through the opening between 5 the legs of the U-shaped part. As can be seen, the U-shaped part contains a bottom 410 perpendicular to the plane V of the screen 20. Furthermore, the U-shaped part also contains two legs 412, 414 extending from the bottom 410 along and on either side of the plane V of the screen 20. As can be seen in the design shown, the two legs 412, 414 are parallel or nearly parallel, as well as parallel or 10nearly parallel to the plane V of the screen20. Additionally, the design of the U-shaped section also contains two mutually oriented spans416,418. As can be seen, these spans416,418 are positioned at the corresponding end of the two legs412,414. From there, these mutually oriented spans416,418 partially span the opening between the two legs412,414. According to the design example shown15, as shown for example in Figure 3, these spans416, 418 in this way ensure the securing of the screen profile300, so that the screen profile is held in the U-shaped section of the removable profile400 when a force is applied to it through the screen20 with a component following the transverse direction D. As can be seen containing the spans416,418 with parts at their ends that extend along the transverse direction D20. These preferred load-bearing parts assist in surrounding the screen profile300, form a stop for the maximum deflection of the screen profile300, and also form a suitableguiding surface for a bottom batten extending along the transverse direction between both side guides200 and, as known to the professional, is fitted at the bottom of the screen20 to guide the underside of the screen20. However, it is clear that alternative designs25 are possible, whereby the spans416,418 have any other suitable shape, which deviates from the shape shown in the figures.

[072] The design shown in Figure 1 to Figure 5 shows a design of the fastening profile 500 containing a U-shaped part. The U-shaped part of the fastening profile 500 contains a base 510 perpendicular to the plane V of the screen 20. The U-shaped part further contains 30 two parallel legs 512, 514 which extend from the base 510 along and on either side of the plane V of the screen 20. It is clear that the base 510 and the legs BE2025 / 5031 19 512, 514 on their outward-facing side form a fastening surface for attaching the fastening profile to a building structure, such as for example a wall orany suitable fastening surface or structure. According to the design shown, it is clear that, in the cross-section as shown in Figure 3 to Figure 5, the bottom 510 extends according to or nearly according to the width direction and both legs 512, 514 extend according to or nearly according to the transverse direction D.

[073] As can be seen further, the design of the first coupling 600 contains a first coupling part 610 and a second coupling part 620. The second coupling 700 also contains a first coupling part 710 and a second coupling part 720.

[074] The first coupling part610 of the first coupling 600 contains, as shown in the 10 cross-section from Figure 3 to Figure 5, a projection that extends in one direction away from the plane V of the screen 20 from the first leg 412 of the U-shaped part 410 of the removable profile 400.The second coupling part620 contains, as shown in the cross-section from Figure 3 to Figure 5, a projection that extends in one direction towards the plane V of the screen 20 from thefirst leg512 of the fastening profile500. It is clear, as shown in Figure 5, that in the fixed state, the first coupling part610 leans against the second coupling part 620 and is situated between the second coupling part620 and the base510 of the fastening profile500. It is clear that in this way the first coupling600 is in a coupled state in the fixed state, whereby the first coupling600 prevents a displacement of the removable profile400 in the direction of the transverse direction D away from the base510 of the 20 fastening profile200 at the height of the first coupling600.

[075] The first coupling part710 of the second coupling700 contains, as shown in the cross-section from Figure 3 to Figure 5, a hook-shaped element attached to the U-shaped part410 of the removable profile400. This hook-shaped element contains, as visible, an end directed in one direction toward the plane V of the screen20.The second coupling part72025 contains, as shown in the cross-section from Figure 3 to Figure 5, a hook-shaped elementthat is attached to the base510 of the mounting profile500. This hook-shaped element contains, as shown, an end that is directed in a direction away from the plane V of the screen20. As shown in Figure 5, in the mounted state, the projection of the first coupling part710 rests against the projection of the second coupling part720 and the projection of the first coupling part710 is located between the second coupling part720 and the base510 of the mounting profile500. Here too, it is therefore clear that in this way the second coupling700 is in a coupled state in the mounted state, whereby the second coupling700 prevents a displacement of the removable profile400 in the direction of the transverse direction D away from the base510 of the mounting profile200 at the height of the second coupling700.

[076] It is therefore clear that in the confirmed state in Figure 5, the first coupling600 and the second coupling700 are coupled states and a movement of the removable profile5400 relative to the fixing profile 500 along the transverse direction D prevent as a result of a force exerted by the screen 20. As described above, it is also clear that the first coupling 600 and the second coupling 700 between the fixed states and the removable state shown in Figure 4 can be moved by a displacement along the width direction B. In the state shown in Figure 4 and Figure 5, from the 10 fixed state in Figure 5, the removable state in Figure 4 can be reached by means of a displacement of the removable profile 400 along the width direction B away from the leg 512 of the fixing profile 500 to which the second coupling part 620 of the first coupling 600 is attached. It is clear that following a reverse displacement of the removable profile 400 relative to the fixing profile 500 from the removable 15 state in Figure 4, the confirmed state of Figure 5 can be achieved. It is furthermore clear that in the removable state of the side guide 200 the first coupling 600 and the secondcoupling700be in a disengaged state, whereby a displacement of the removable profile400 relative to the fixing profile500 along the transverse direction becomes possible in order to remove the removable profile400 from or attach it to the 20 fixing profile as described above.

[077] As described above, the removable profile400 and the fixing profile500 further form a safeguard800, in which, in the fixed state, a locking element900 can be removablely installed to prevent mutual movement perpendicular to the planeVofthescreen20. In other words, the safeguard800 and the 25 locking element900 ensure, in the fixed state, that movement along the width direction Bof the removable profile400 relative to the fixing profile500 is prevented, whereby the first coupling600 and the second coupling700 in the coupled state are secured by the locking element900 when it is inserted into either the first locking part810 and the second locking part820, or in other words when the first locking part810 with the 30connects second locking part 820. It is clear that the first locking part 810 is installed next to, or along, the second leg 414 on the BE2025 / 5031 21 outside of the U-shaped part of the removable profile 400, in accordance with the shown execution example. As is further visible, the second locking part 820 is attached to the base 510 of the U-shaped part of the fastening profile 500, in accordance with the shown execution form. As shown in Figure 5, the positioning of the first locking part 810 and the second locking part 820 is configured so that they align with each other along the width direction B in the fixed position as shown in the cross-section of Figure 55 for the insertion of the locking element 900 into both locking parts 810, 820. It is clear that alternative execution forms are possible here as well, other than the execution form shown in the figures.

[078] However, it is clear that a number of alternative forms of execution are possible for the first coupling600 and the second coupling700, than the form of execution shown in Figure 3 toFigure 5. According to such design forms, for example, the first coupling 600 contains a first 10 coupling part 610 attached to the removable profile 400 and a second coupling part 620 attached to the mounting profile 500. In this case, the first coupling part 610 and the second coupling part 620 are configured to move between the mounted states and the removable state by means of mutual movement perpendicular to the plane V of the screen 20. The second coupling 700 contains, according to such design forms, for example, a first 15 coupling part 710 attached to the removable profile 400 and a second coupling part 720 attached to the mounting profile 500. This first coupling part 710 and the second coupling part 720 are also configured to move between the mounted state and the removable state by means of mutual movement perpendicular to the plane V of the screen 20.

[079] As can be seen, the design form of the side guide 200 further contains 20 preference a third coupling part 630 for the first coupling 600 and a third coupling part 730 forthe second coupling 700 which are attached to the mounting profile 500. As will be described in detail below, this allows the removable profile 400 to be attached to the mounting profile 500 selectively, in two different orientations. A first orientation is illustrated in Figure 3 to Figure 6. The second orientation is shown in similar 25 views from Figure 7 to Figure 10. In the example shown, as visible, the second coupling part 620 and the third coupling part 630 of the first coupling 600 are mounted symmetrically or nearly symmetrically with respect to a plane S centrally between both legs 512, 514 of the mounting profile 500. It is clear that the plane S is parallel to the plane V of the screen 20 and that it is located in the middle or nearly in the middle between 30 extends both legs 512, 514 of the mounting profile. According to the shown design, the second coupling part 720 and the third coupling part 730 of the second coupling are also BE2025 / 5031 22applied symmetrically or nearly symmetrically with respect to this central plane S of the fastening profile 500. In other words, according to the shown design with respect to the plane S central between both legs 512, 514 of the fastening profile 500, the distance of the second coupling part 620 and the third coupling part 630 of the first coupling 600 is equal or nearly equal, and the distance of the second coupling part 720 and the third coupling part 730 of the second coupling 700 is equal or nearly equal. In other words, the second coupling part 620 and the third coupling part 630 of the first coupling 600 are located equally far or nearly equally far from this plane S, as well as the second coupling part 720 and the third coupling part 730 of the second coupling 700 are located equally far from this plane S. It is clear that alternative execution forms are possible whereby bits with respect to a plane S10 centrally between both legs 512, 514 of the fastening profile 500 the distance of the second coupling part 620 and the third coupling part 630 of the first coupling 600 and / or the distance of thesecond coupling part 720 and the third coupling part 730 of the second coupling 700, for example, contain a percentage difference of 10% or less, preferably contain a percentage difference of 5% or less.15

[080] Figure 7 to Figure 10 show similar views to Figure 3 to Figure 6 respectively, where only the orientation of the removable profile 400 with respect to the fixing profile 500 was adjusted. As can be seen, the removable profile 400 was rotated 180° with respect to the orientation shown in Figure 3 to 6, from an axis parallel to the transverse direction D. It is clear that similar elements were indicated with similar references and exhibit similar structural and functional characteristics as described above. For the displayed form of execution, reference will be made to the first orientation with respect to Figure 3 to Figure 6 and the second orientation with respect to Figure 7 to Figure 10. However, it is clear that this is merely an example and that in any suitable manner two suchdifferent orientations as desired, the first or the second can be called.25

[081] In the first orientation, as described above, the first coupling600of the removable profile400contains the first coupling part610attached to the removable profile400 and the second coupling part620attached to the mounting profile500. In other words, in this orientation the first coupling600of the removable profile400 is formed by these coupling parts610,620. As described with respect to Figure 3 to Figure 530, the first coupling part610 and the second coupling part620 of the first coupling600 BE2025 / 5031 23 are configured to move perpendicular to the planeVofthescreen20 between the mounted state and the removable state by means of mutual movement.

[082] As shown in Figures 7 to 9, in the second orientation the first coupling 600 of the removable profile 400 contains the first coupling part 610 attached to the removable profile 400 and the third coupling part 630 attached to the mounting profile 500. With 5In other words, in this orientation the first coupling of the removable profile is formed by the same coupling part of the removable profile as in the first orientation, but with a different coupling part of the mounting profile in the second orientation. As shown in Figure 8 and Figure 9, the first coupling part and the second coupling part of the very first coupling are also configured by moving the mutual movement perpendicular to the plane of the screen between the mounted state of Figure 9 and the removable state of Figure 8. It is clear that in the second orientation the direction of movement is reversed compared to the first orientation. In other words, in the orientation shown in Figure 8 and Figure 9, a movement to the left of the removable profile 400 relative to the mounting profile 500 is required to move the removable state. towards the confirmed state, and a movement to the right for the reverse movement. This in contrast to a movement to the right of the removable profile400 relative to themounting profile 500 for moving from the removable state to the fixed state, and a movement to the left for the reverse movement in the first orientation of Figure 5 and Figure 6.20

[083] Similar to what is described above for the first coupling 600, the second coupling 700 also contains the possibility to be used in a second orientation of the removable profile 400 relative to the mounting profile 500. In the first orientation of the removable profile, the second coupling 700 contains the first coupling part 710 attached to the removable profile 400 and the second coupling part 720 attached to the mounting profile 500. In addition, as described above, the first coupling part 710 and the second coupling part 720 are configured to move between the fixed states and the removable states by means of mutual movement perpendicular to the plane V of the screen 20 by means of mutual movement state to move as shown in Figure 4 and Figure 5.

[084] In the second orientation of the removable profile 400, the second coupling contains 70030Likewise, the first coupling part 710 is attached to the removable profile 400, but unlike in the first orientation, the second coupling 700 contains the third coupling part 730 attached to BE2025 / 5031 24 the mounting profile 500. As can be seen, the first coupling part 710 and the third coupling part 730 are configured to move perpendicular to the plane V of the screen 20 between the attached state and the removable state by means of mutual movement. Similar to what is described above with regard to the first coupling 600, here too the direction of movement in the second orientation is opposite to the direction of movement in the first orientation during a movement between the removable state in Figure 8 and the attached state in Figure 9.

[085] Additionally, it is clear that the safeguard 800 and the safeguard element 900 are applied according to the shown execution example in such a way that they extend to, nearly to, or along the plane of symmetry in the cross-section as shown in Figure 3 to Figure 10.10However, it is clear that alternative forms of execution are possible whereby the securing element 800 and the securing element 900 are installed at other suitable locations and / or whereby use is made, in a similar manner as described above, of a third coupling part that is installed symmetrically or nearly symmetrically with respect to the central fin S with the second securing part 820 to enable securing in the two orientations of the removable profile 40015.

[086] However, it is clear that many other configurations are possible, in which the removable profile400 is configured to be attached to the mounting profile500 in two different orientations. As explained in Figure 6 and Figure 10, for example, such flexibility is advantageous for realizing a side guide200 using the same profiles, the plane of the screen20 of which can be positioned at two different distances from, for example, the window. This also promotes the efficiency of disassembly as well as the robustness.since, after mounting the mounting profile, the removable profile can always be positioned on the mounting profile in the desired orientation.

[087] Furthermore, it is clear that the removable profile400 on both sides of the U-shaped part25 preferably contains a cover surface420 that forms the visible part of the removable profile400 and that preferably extends transversely to the planeV of the screen20 to the ends of the legs512,514 of the fastening profile500. As shown, suitable openings are preferably made in this cover surface420 for attaching the locking elements 900.30

[088] However, it is clear that alternative designs are possible for the side guide as shown in Figure 1 to Figure 10. For example, it is possible that instead of a BE2025 / 5031 25 side guide200 with a U-shaped fastening profile500, a design similar to shown in Figure 11 to Figure 13 is used. Similar elements were indicated with similar references and contain similar structures functionalcharacteristics as described above. Figures 11 to 13 show similar states to those shown in Figures 3 to 5, in other words a removed state, a removable state and a fixed state. This version differs from the form of execution described above in the fact that the fixing profile contains only one leg next to the bottom transverse to the plane V of the screen, which extends from the bottom along the plane V of the screen. In other words, the fixing profile contains an L-shaped cross-section instead of a U-shaped cross-section. Such a profile offers the advantage that it can be executed more compactly along the width direction B. However, the flexibility to mount the removable profile 400 in two different orientations on the fixing profile 500 is not present here. It is nevertheless possible to use the removable profile 400 of this design with the fixing profile 500 of the design shown in Figure 1 to Figure 10, such as, for example, 15shown in Figure 14. Such a design is advantageous, for example, when it is desired to attach another element in the space between the removable profile 400 and the leg 514 of the U-shaped profile. For example, it is possible to install a frame or profile for a horor insect screen in this space that is, for instance, not rollable up and down, alongside, for example, a blackout screen 20 that is rollable up and down in the removable profile 400 as described above. It is clear that numerous alternative designs are possible. It is further clear that in the design shown in Figure 14, the removable profile 400 can also be mounted on the U-shaped mounting profile 500 in two different orientations. In this way, maximum flexibility for the manufacture and assembly of side guides 200 can be realized with a minimum of different profiles 25. 400,500.It is clear that in both versions the same or similar version of a screen profile300 can be used.

[089] As can be seen in, for example, Figure 1, Figure 6 and Figure 10, the design of the screen device10 also contains a winding device100 for winding the screen20 onto a winding shaft110. As can be seen, the winding device100 is mounted at the top of two side guides200, also known as a vertical installation. The schematically shown winding device100 is designed similarly to the winding device100 known from EP3372773 BE2025 / 5031 26 which is included here by means of reference. Similar to as described in EP3372773, the winding device100 contains an inner space in which the winding shaft110 can be removed and installed by means of fastening elements120 which are attached to the head sides, also known as the outer ends, of the the winding shaft 110 can be attached to a fastening body in the interior of the housing of the winding device 100 via a vertical movement. 5

[090] These steps are a form of a method for mounting or dismounting.The screen device is illustrated using Figures 15 to 22. Although this method is advantageous in combination with the side guide design forms as described above, it is clear that, according to another aspect, the screen device shown and the associated mounting and dismounting method, which makes use of the described roll-up device and removable locking elements, is also advantageous when used in combination with alternative design forms of a screen device in which side guides are used with a removable profile that is removablely mounted to a mounting profile.

[091] Figure 15 shows how a roller shaft 110 with a screen rolled up onto it and the fastening elements 120 at its 15 ends can be inserted into the fastening profiles 500 of the side guides 200 in order to be brought upwards to the roller device 100. It is clear that alternative designs are possible where the screen is not or not fully on the roller shaft110 is rolled. Next, Figure 16 shows the step where the winding shaft 110 was secured in the winding device 100 by means of the fastening elements 120, after which a design of a locking element 130, as shown, can be fitted at the height of the 20 two side guides 200. Figure 17 shows the step where one end 134 of the locking element 130 is inserted into a slot in the housing of the winding device 110. As shown in the cross-section perpendicular to the longitudinal axis of the winding shaft 110 in Figure 27, the end 134 is fitted into a corresponding slot 104 of the housing of the 25 winding device 100 according to the design shown. It is clear that preferably the cross-section of the end 134 and the corresponding slot show a corresponding outline, preferably as shown an arc-shaped, or curved outline, which facilitates tilting the locking element 130 during assembly or disassembly. Figure 18 shows the step where the other side 136 of the locking element 130 is clicked onto the housing of the winding device 100. It is 30It is clear, as for example visible in Figure 27, that in the confirmed position this side 136 clicks firmly into place onto the corresponding protrusions 106 of the housing of the winding device BE2025 / 5031 27 100. However, it is clear that a number of alternative designs are possible other than the design shown in Figure 27, whereby a rigid removable connection can be realized. Preferably, the connection is a click connection.

[092] In Figure 19, the execution of this method for mounting the screen device 10 is continued by providing a cover plate 140 for the 5 underside of the housing of the winding device 110. As shown in Figure 20, according to the execution, the first end 148 of the cover plate 140 is placed in a slot 108 of the housing of the winding device 100 as also shown in more detail in Figure 27. Next, in Figure 21, the cover plate 140 is clicked onto the locking element 130 by inserting the projection 142 of the cover plate 140 into the slot 132 of the locking element 130 so that a shape-retaining 10a removable click connection is created. It is further clear that, as visible in Figure 27, in this state, the cover plate 140 prevents the locking element 130 from being removed. In other words, the cover plate 140 secures the locking elements 130. In other words, after installing the cover plate 140 in this configuration, the locking elements 130 can no longer be unclipped. This is only possible again after removing the cover plate 140.15

[093] Finally, in a subsequent step, the removable profile 140 of the side guide 200 is attached to the fastening profile 500 as shown in Figure 22, where it is clear that in this state the locking element 130, as well as the cover plate 140, can no longer be removed in this configuration.

[094] It is clear that the above form of execution of the method for assembling a screen device10 also describes a form of execution of a method for disassembling the screen device10 in which the preceding steps are performed in reverse order.

[095] It is clear that alternative designs are possible in which the winding device 100 contains at least two corresponding removable locking elements 25 at the height of the two side guides 200 that are configured to prevent the winding shaft 110 from being removed from the winding device 100. It is clear that the locking elements 130 are configured so that they can only be removed when the removable profile 400 has been removed from the corresponding side guide 200.

[096] Figure 23 shows a fragment of a cross-section through a design of the winding shaft 110 with a screen rolled up onto it similar to those shown in Figure 15 to Figure 22. As can be seen, a fastening element 120 is fitted at the end of roller shaft 110, which is secured by the locking element 130 to which the cover plate 140 is attached on the underside. As can be seen, the locking element 130 contains upward protrusions 131 to achieve the locking, which prevent movement of the fastening element 120 in the transverse direction D.to prevent the removal of the winding shaft 110 from the winding device 100. In the depicted version, two upward projections 131 are fitted to the locking element 130, 5 it is however clear what suitable number, such as one or more, is possible according to alternative designs. Figure 24, Figure 25 and Figure 26 further show this design of the locking element 130 in a side view, a top view and a perspective view. In addition, the click connection 132 for the removable installation of the cover plate 140 is also visible. However, it is clear that a number of variant designs are possible in which the 10 locking element 130 is configured so that it can only be removed when the removable profile 400 is removed from the corresponding side guide 200 and which can preferably be attached to the winding device 100 in a removable manner without additional fasteners. Preferably, the locking elements 130 are configured to be attached in a removable manner to the housing of the winding device 100 by means of a click connection. 15Preferably, the cover plate 140 is also configured to be removablely attached to the locking elements 130 by means of a click connection.

[097] According to the execution example shown in Figure 23 and Figure 27, the execution of the locking elements further contains a stop surface 138 for the cover plate. This allows the cover plate 140 to be leaned against this stop surface 138 of the 20 locking elements 130 for positioning the cover plate 140 in the attached state. It is furthermore clear from Figure 23 that the design of the cover plate 140 can also only be removed when the removable profile 400 has been removed from the corresponding side guide 200. Furthermore, the cover plate 140 prevents the winding shaft 110 from being removed from the winding device 100 when the cover plate 140 is in place. Thus, a double locking 25 of the winding shaft 110 is created according to this design, once by the locking elements 130 and a second time by the cover plate 140.

[098] Furthermore, it is also visible that according to the design shown, the locking elements130two stop surfaces102 contain for corresponding stop surfaces of a bottom bar150 fitted at the bottom of the screen20. In this way, the locking elements can prevent the bottom bar30 150 from penetrating the housing of the rolling device100 in an undesirable manner when the screen20 is fully rolled up. This also helps in positioning and centering the bottom bar BE2025 / 5031 29 150 fitted at the bottom of the screen20 in the rolled-up state of the screen as shown in Figure 27. It is clear that a number of alternative designs are possible in which the locking elements130 contain at least one stop surface for a bottom bar150 fitted at the bottom of the screen20.

[099] It is furthermore clear that the design of the winding device100 shown contains two such locking elements130, one at each end of the winding shaft110.

[100] The above designs are particularly advantageous when the winding device100 is mounted in such a way that the winding shaft110 is only removable fromthe roller device 100 via the side guides 200. This is the case, for example, with the execution form as shown in Figure 6 and Figure 10, where the roller device 100 is, for example, installed in a cavity of a wall near a window. However, it is clear that alternative execution forms are possible, where this is also advantageous, such as when the roller devices and / or the side guides are at least partially embedded in the plastering of a wall,….

[101] As further shown in Figure 6 and Figure 10, support feet 160 are fitted to the underside of the side guides 15 200 of the design of the screen device 10, which support the mutual alignment of both side guides 200. As can be seen in this design, a combination is fitted of a foot 162 with a slope as shown in the side view and top view of Figure 30 and Figure 31, and a foot 164 without a slope as shown in the side view and top view of Figure 28 and Figure 29. The slope of the foot 20162 preferably corresponds to the slope of the surface on which the side guide is mounted, such as, for example, the slope of a window sill,…. Such a modular foot containing two different parts162,164 is advantageous since it allows the side guide200 to be mounted efficiently on a surface that does or does not contain a slope. However, it is clear that alternative designs are possible in which any suitable25 foot is used to achieve a good connection with the ground surface. In this regard, it is advantageous that the screen installation10 contains a foot160 consisting of a selection of one or more connectable feet162,164 from the following combination: a sloping foot 162; and / or a foot without a slope164.

[102] It is clear that this invention is not limited to specific forms of execution or combinations as described herein, since such forms of execution and combinations thereof can naturally vary. Let it also be clear that the terminology used herein BE2025 / 5031 30not intended as restrictive. The scope of protection is determined by the attached claims.

[103] As used herein encompassing singular forms “a”, “the”, “it” both the singular and the plural forms when context is clearly different.

[104] The terms “contain”, “contains” as used hereinafter, are synonymous with “inclusive”,5 “include” or “comprehensive”, “comprehensive” and are inclusive or do not open or exclude additional, unnamed members, elements or method steps. The terms “comprehensive”, “comprehensive” are inclusive of the term “contain”, “contains” and / or vice versa.

[105] The enumeration of numerical values ​​based on a numerical range includes all values ​​and fractions in these ranges, as well as the cited endpoints.10

[106] The term “approximately”, “essentially”, “mainly”, “virtually” or “approximately”, as used when referring to a measurable value such as a parameter, a quantity, a duration, an angle, a direction, and so on, is intended to enclose variation of + / -10% or less, preferably + / -5% or less, preferably + / -1% or less, and even morepreference + / - 0.1% or less, of and from the specified value, insofar as the variations of 15 apply to function in the invention described herein. It is clear that the value to which the term “approximately”, “essentially”, “primarily” or “by approximation” refers in itself, was also disclosed.

[107] In this, various aspects, forms of execution and / or characteristics are described and / or further defined. Each aspect, form of execution and / or characteristic can be combined with another aspect or aspects, and / or form of execution or forms of execution, and / or characteristic or characteristics unless the contrary is clearly indicated. In particular, a characteristic designated as the “preferred” or “advantageous” can be combined with other characteristics or properties that are mentioned as “preferred” and / or “advantageous”. Reference in this description to “one form of execution” or “a form of execution” means that a certain function, structure or characteristic described in connection with the form of execution applies inat least one form of execution of the present invention. When the phrases "in one form of execution" or "one form of execution" are mentioned in different places in this specification, they do not necessarily refer to the same form of execution, although this is not excluded. Furthermore, the described aspects, forms of execution, features, structures or characteristics may be combined in any suitable manner, as is clear to an expert in the subject matter on the basis of this description. The forms of execution described and claimed in the claims BE2025 / 5031 31 may be used in any combination. The description above refers to the accompanying drawings which form part thereof, and which illustrate specific forms of execution by way of example.
