Abstract

A screen device (10) is described for a retractable screen (20). The screen device (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 removable profile (400) and the mounting profile (500) form a first coupling (600) and a second coupling (700) which are configured to move between a mounted state and a removable state by means of mutual movement perpendicular to the plane (V) of the screen (20). The removable profile (400) and the mounting profile (500) further form a locking mechanism (800) in which a locking element (900) can be installed. In the secured state, the first coupling (600) and the second coupling (700) are on the same side of the locking mechanism (800).

Description

2 great care must therefore be taken to correctly install the first part of the screen guides of the screen installation in relation to the plane of the window, the door, etc. in which they are installed.

[006] Additionally, it is advantageous when the screen installation allows the screen to be removed from the screen installation in the direction of the screen guides. This is particularly advantageous when, for example, the roller device for the screen 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 roller device is mounted in a cavity or behind another permanent structure of the building near an opening for a door, a window, etc.

[007] There is therefore a need for a screen device that can cope with the aforementioned disadvantages10 and at the same time offers greater flexibility, is easier to disassemble and disassemble, can cope with a greater load, and / or can cope with a load in a more reliable manner. Summary15

[008] According to a first aspect of the invention, provision is made for a screen device fora longitudinally retractable screen containing a corresponding thickening along two sides opposite in a transverse direction, the screen device containing the two elongated side guides fitted to guide the screen and 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 retraction in the longitudinal direction; and -enclosing the thickening to hold the thickening within the screen profile; -a one-piece removable profile configured for enclosing the screen profile to hold the screen profile within the removable profile; and -a one-piece fastening profile configured for the removable fastening of the removable profile, CHARACTERIZED BY THE FACT THAT -the removable profile and the fastening profile a first coupling and a second coupling forming which, in a fixed state, are located on either side of the plane of the screen, BE2025 / 5030 3and which are configured to move between a fixed state and a removable state by means of mutual movement perpendicular to the plane of the screen; -the removable profile and the fixing profile form a locking mechanism, in which, in the fixed state, a locking element can be removablely installed to prevent mutual movement perpendicular to the plane of the screen; and -in the fixed state, in a direction perpendicular to the plane of the screen, the first coupling and the second coupling are located on the same side with respect to the locking mechanism.

[009] In this way, a screen system is realized with a minimum number of parts, which offers the flexibility of removing the removable profile even when the screen profile has been 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 profilerelative to the fixing profile, it is sufficient to move between a fixed state and a removable state of the removable profile. Moreover, the specific location of the couplings ensures that they are positioned close to and on both sides of the screen surface15, enabling them to withstand a greater load and cope with a load in a more reliable manner. Furthermore, the safeguards and the safeguard element are thus at least partially shielded from the greatest load exerted on the side guide by the screen.

[010] According to a design, a screen device is provided, whereby:20 -the first coupling contains: -a first coupling part attached to the removable profile; and -a second coupling part attached to the mounting profile, whereby the first coupling part and the second coupling part are configured to move between the mounted states 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 perpendicular to the plane of the screen between the mounted state and the removable state by means of mutual movement. BE2025 / 5030 4

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

[012] In accordance with a design, a screen device is provided, whereby: -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;5 -two legs extending from the bottom along and on either side of the plane of the screen; and -two mutually oriented spans partially spanning from the corresponding end of the two legs and the opening between the two legs; -the fastening profile contains:10 -a bottom perpendicular to the plane of the screen; and -at least one leg extending from the bottom along the plane of the screen;- the first coupling contains: - a first coupling part that contains or consists of a projection that protrudes in a direction away from the plane of the screen from a first leg of the U-shaped part of the 15 removable profile; and - a second coupling part that contains or consists of a projection that protrudes in a direction towards the plane of the screen from a first leg of the mounting profile, in which the in the attached state, the first coupling part leans against the second coupling part and is located between the second coupling part and the bottom of the mounting profile;20 - 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 oriented in a direction towards the plane of the screen; and -a second coupling part that contains or consists of a hook-shaped element on the bottom 25 of the mounting profile is attached and that contains an end that is directed away from the plane of the screen in a direction, whereby in the mounted state the projection ofthe first coupling part leans against the projection of the second coupling part and is located between the second coupling part and the base of the mounting profile.

[013] This allows the couplings to be realized with simple and reliable elements.30

[014] According to a design form, a screen device is provided in which: - the mounting profile contains a U-shaped part, where the U-shaped part contains: BE2025 / 5030 5 - a base perpendicular to the plane of the screen; - two parallel legs extending from the base along and on both sides of the plane of the screen.

[015] This offers the advantage that the mounting profile can easily be attached to a building in different orientations.5

[016] According to a design, a screen system is provided in which the removable profile is configured to be selectively attached to the mounting profile in two different orientations.

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

[018] According to a design, a screen device is provided in which: -the first coupling in a first orientation of the removable profile contains: -a first coupling part attached to the removable profile; and -a second coupling part attached to the mounting profile, whereby the first coupling parts and the second coupling part are configured to move by means of mutual movement perpendicular to the plane of the screen between the attached states andto move removable state; and -the first coupling in a second orientation of the removable profile contains: -a first coupling part attached to the removable profile; and 25 -a third coupling part attached to the mounting profile, whereby the first coupling part and the second coupling part are configured to move perpendicular to the plane of the screen between the attached state and the removable state by means of mutual movement; and -the second coupling in the first orientation of the removable profile contains: 30 -a first coupling part attached to the removable profile; and -a second coupling part attached to the mounting profile, BE2025 / 5030 6 whereby the first coupling part and the second coupling part are configured to move perpendicular to the plane of the screen between the attached state and the removable state by means of mutual movement; and -the second coupling in the second orientation of the removable profile contains: -a first coupling part of the removable profile has been applied; and 5-a third coupling part is attached to the mounting profile, whereby the first coupling part and the third coupling part are configured to move perpendicular to the plane of the screen between the attached state and the removable state by means of mutual movement.

[019] In this way, the selective attachment of the removable profile can be realized in a simple manner.

[020] According to a design, a screen device is provided in which, with respect to a plane centrally located between both legs of the mounting 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:15 - are equal or nearly equal; - contain a percentage difference of 10% or less; - contain a percentage difference of 5% or less.

[021] This allows the coupling parts of the mounting profile for selectively attaching the removable profile to be realized in a simple manner, which also makes it easy for an installer20makes it easy to carry out the fastening in both orientations since the symmetrically arranged coupling parts allow for similar fastening in both orientations.

[022] According to a design, a screen device is provided in which: -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 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 has been removed. BE2025 / 5030 7

[023] In this way the rollers and optionally a rolled-up screen can be installed in the roller device in an efficient and simple manner after the side guides have already beeninstalled under the roller device, without creating the risk that in the fixed state of the side guides, where the removable profile was also installed, the roller shaft could come loose from the roller device in an undesirable manner.5

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

[025] 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 accessible for installing and / or removing the roller shaft for the screen.

[026] According to a second aspect, a method is provided for assembling or disassembling a screen device according to the first aspect, whereby the method contains the following step:15 -by means of a mutual movement perpendicular to the plane of the screen the between ain the fixed state and a removable state, movement of the removable profile and the fixing profile.

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

[028] According to a design, 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.

[029] This ensures that the locking element and the locking mechanism are optimally shielded by the couplings and preloads on the side guides generated by the screen.

[030] According to an execution form, a method is provided, whereby the method further contains the following step: -the selective application of the removable profile to the fastening profile in one of two 30 different orientations. BE2025 / 5030 8

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

[032] According to an execution form, a method is provided, whereby the method contains the following steps:5 -applying the removable profile in a first orientation by: -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;10 -applying the removable profile in a second orientation by: -forming the first coupling with the first coupling part and the third coupling part of the first coupling; and -forming the second coupling with the first coupling part and the third coupling part of the second coupling;15

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

[034] According to an execution form, a method is provided which contains the following steps:

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

[036] 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 attached to the fastening profile of the side guide in the fixed state.

[037] According to an execution form, a method is provided whereby the method contains the following steps: -attaching the winding device to a building so that the winding shafts can only be removed from the winding device via the side guides.30

[038] The method is particularly advantageous in similar circumstances where the winding shafts can only be attached or removed from the winding device in this manner. BE2025 / 5030 9

[039] 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 against 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 within the screen profile; -a one-piece removable profile configured for surrounding the screen profile to hold the screen profile in the removable profile; and -a one-piece mounting profile configured for the removable mounting of the removable profile, CHARACTERIZED BY THE FACT THAT -the screen device is furthermore a winding device for winding up the screen onto a winding shaftcontains, whereby the winding device is removablely mounted at the top of the two side guides by means of fastening elements; -the winding device contains a removable locking element at least at the height of the two side guides that is configured to prevent the winding shaft from being removed from the winding device when installed; and -the locking element is configured so that it can only be removed when the removable profile of the corresponding side guide is removed.

[040] In this way, a screen system is realized in which the winding shaft can be installed in the winding device efficiently and reliably. Moreover, the locking element that cannot be removed in the fixed state of the side guide ensures that the screen system 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.

[041] According to an execution form, a screen arrangement is provided, whereby thelocking elements are configured to be removablely attached to the housing of the 30 winding device by means of a click connection. BE2025 / 5030 10

In particular, designs of an aspect are possible that contain one or more characteristics, as well as variants and / or combinations of similar characteristics of one or more designs of another aspect.

Detailed description20

[054] Figure 1 shows a schematic and perspective view of a 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 device100.25 As is known to a professional, such a screen20 can be rolled up and down in a longitudinal direction L as indicated in Figure 1. Figure 2 shows a view in this longitudinal direction L of the design of the screen20.

[055] As visible in Figure 2, the design of the screen20 along two sides opposite in a transverse direction D2,24 contained a corresponding thickening26,28.30 It is clear that the transverse direction D is transverse to the longitudinal direction L, and that the transverse directionalong the longitudinal direction L form the plane V of the screen, or in other words the plane V in which BE2025 / 5030 13 the screen20 is in the unrolled state. It is clear that variant designs are possible for the shown thickening26,28 on each of the opposite sides22,24, also known as lateral sides, of the screen20. The thickening can, for example, contain or consist of half of a zipper or other suitable thickening applied to or on the screen along the sides22,24. It is further clear that this thickening26,28 extends along the respective 22,24 in the unrolled state of the screen 20 in accordance with the longitudinal direction L. Depending on the design, the thickening can extend over the entire length. of the screen20, however, alternative forms of execution are possible whereby the thickening is applied only to a part of the length of the screen20 and / or according to a specific pattern, for example a repetitive pattern along the longitudinal direction applied to the screen.10

[056] 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 professional, 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 in an elongated manner along the longitudinal direction.

[057] The design of the side guides 200 as shown in Figure 1 is explained in more detail using Figures 3 to 5, which show a cross-section of the side guide 200, in other words along 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 planeVfromthescreen20,orinotherwordstransversetothelongitudinaldirectionLandtransversedirectionD.

[058] Figures 3 to 5 show different steps of a method for assembling the side guide 200 version. Figure 5 shows the assembled state of the side guide 200 version, and Figures 3 and 4 show two steps for disassembling or assembling 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 configured to guide the thickening during rolling up and down according to BE2025 / 5030 14 longitudinal direction L. As further visible, such a screen profile 300 is also configured to surround the thickening 26 of the screen 20 around the thickening 26 in the screen profile300to keep. 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 in the slot cannot leave through the opening in the slot 310. As further visible, the design of the screen profile 300 may contain a base 320 to which the slot 310 is attached, as well as elastic elements 330 which are placed between the base 320 and a removable profile 400, for example to keep the screen 20 under tension. Such elastic elements may contain or consist of one or more suitable springs, or one or more 10 elements of a suitable elastic or resilient material such as, for example, rubber,….

[059] It is clear that the screen profile300 is an elongated profile that extends along the longitudinal direction L. When unrolling and rolling up the screen20, the bottom of the screen20 therefore typically moves downwards or backwards from the top of this screen profile300.upwards to this top side. In doing so, the thickening26 of the screen20 slides through the 15 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 direction Len and held along the transverse direction D.20

[060] It is clear that a number of variant design forms are possible, other than the design form of the screen profile300 as shown in Figure 3. For instance, variations are possible regarding the shapes and dimensions of the slot310 and the base320 and design forms are possible whereby in instead of and / or additionally elastic elements330 for example tensioning elements are present such as, for example, mechanical, magnetic, … tensioning elements which can appropriately bring and / or keep the screen25 20 under tension. The screen profile300 can be manufactured froma suitable metal or plastic, preferably with a material with a low coefficient of friction.

[061] 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 configured, as visible, to surround the screen profile 300 in order to hold the screen profile 30 in the removable profile 400. The one-piece fixing profile 500 is configured, as visible, for the removable fixing of the removable profile 400. BE2025 / 5030 15 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 it is clear that alternative designs are possible where the profiles are manufactured from any suitable metal or plastic.5

[062] As shown in Figure 3 to Figure 5, the removable profile 400 and themounting profile 500, 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 5, 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 the left, of the removable profile 400 relative to the mounting profile 500, the first coupling 600 and the second coupling 700 of the fixed state shown in Figure 15 move. 5 to the removable state shown in Figure 4. It is clear that in the confirmed state shown in Figure 5 the removable profile 400 is removablely attached to thefastening profile 500. It is furthermore clear that in the removable state shown in Figure 4, the removable profile 400 can be removed from the fastening profile 500, 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 profile 400 can be inserted into the fastening profile 500, 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. Subsequently, for example, from the removable state of Figure 4, the fixed state shown in Figure 5 can be reached by a movement along the width direction B, in the orientation shown in Figure 5 to the right.

[063] As further visible in Figure 5, the removable profile 400 and the fastening profile 500 contain and form a locking mechanism 800. In this locking mechanism 800, as shown in Figure 5, in the 30confirmed condition a retaining element 900 can be installed removablely. It is clear that this retaining element 900 installed in the confirmed condition BE2025 / 5030 16 prevents mutual movement across the plane V of the screen20, or in other words along the width direction B.

[064] According to the design shown, the retaining element 900 is designed as a bolt 900. However, it is clear that alternative designs are possible, such as a screw, a pin, a snap element, a clamp element, etc., which can be installed removablely in the retaining condition.

[065] According to the design shown, the safeguard 800 contains a first safeguard part 810 and a second safeguard part 820. It is clear that the removable profile 400 contains the first safeguard part 810 and that the fastening profile 500 contains the second safeguard part 820. The design of the first safeguard part 810 contains, as shown, a part of the 10 removable profile 400 with a surface that is configured around the safeguard element 900removable to be attached. For the execution example shown, these are profiled surfaces on which the thread of the 900 bolt can engage. However, it is clear that alternative execution forms are possible where alternative surfaces are possible for cooperation with alternative locking elements.15

[066] As visible in Figure 3, in the removed state, the 900 locking element can already be installed in the first locking part 810. According to the execution example shown, this means that the 900 bolt is partially screwed into the first locking part 810. In the removable position of Figure 4, this is also the case. As shown in Figure 4, the second locking part 820 is preferably configured so that in this removable state, the 900 bolt is prevented from reaching as far out of the removable part 400 as the displacement according to the width direction B towards the confirmed deposition in Figure 5 would be prevented. As is visible, in this removable condition of Figure 4, the second safeguarding part 820 functions asa stop for the bolt 900, so that further movement of the outer end of the bolt 900 in the direction of the mounting profile 500 is prevented. This allows a movement in 25 the width direction B between the removable condition in Figure 4 and the fixed condition in Figure 5 remains possible. As shown in Figure 5, the first securing part is 810 and the second securing part 820 are aligned with each other in such a way that the bolt 900 can be screwed further into the second securing part 820.

[067] As shown in Figure 6, an embodiment of the screen device 10 can have several 30 such securing elements 900 arranged at various locations along the side guide 200 to secure the couplings 700, 800 of the side guide 200 in the attached condition. BE2025 / 5030 17 As visible in Figure 6, three such securing elements900 are applied. However, it is clear that alternative forms of execution 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 safeguarding elements900.

[068] As shown in Figure 5, it is also clear that according to the configuration shown 5, 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 10 exerted by the removable profile 400 on the mounting profile 500 under the influence of tension or load on the screen 20, or in other words forces, in, or largely in, the direction of the plane V of the screen 20. The safeguarding element 900 in safeguarding 800 must in this way not or virtually not be responsible for absorbing forces in this direction, and provides only or primarily a safeguarding function to 15to prevent a displacement along the width direction B of the removable profile 400 relative to the fixing profile 500.

[069] This offers the advantage that inserting the locking element900 into the locking element800 in the fixed state 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 performed sufficiently consistently, there will still be a secure connection between the removable profile400 and the fixing profile500 by means of the couplings600,700, which can reliably absorb the loads generated by the screen20, the largest component of which extends along the planeV of the screen20. Moreover, the locking element800 and the locking element900 are at least partially shielded by the nearest coupling700 from forces25 generated by the screen20 acting on the side guide200, since this coupling700 between the safeguards the plane V of the screen20 is located according to the width direction B.

[070] 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 penetrate the legs of the U-shaped part into the removable profile 400 through the opening between 30. As can be seen, the U-shaped part contains a bottom 410 perpendicular to the plane V of the screen 20. Furthermore, the U- BE2025 / 5030 18 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 nearly parallel to the plane V of the screen20. Additionally, the design of the U-shaped part also contains two mutually oriented spans416,418. As can be seen, these spans416,418 are placed at the corresponding end of the two legs412,414. From there, these mutually oriented spans span416,418partial the opening between the two legs 412, 414. According to the execution example shown, as for example shown in Figure 3, these spans 416, 418 ensure in this way that the screen profile 300 is secured in the U-10 shaped part of the removable profile 400 when a force is exerted on it through the screen 20 with a component following the transverse direction D. As visible, the spans 416, 418 contain parts at their ends that extend along the transverse direction D. These load-bearing parts help surround the screen profile 300, form a stop for the maximum deflection of the screen profile 300, and also form a suitable guiding surface for a bottom bar that extends along the transverse direction between the two. side guides200 and as known to the professional are fitted at the bottom of the screen20 to guide the underside of the screen20. However, it is clear that alternative designs are possible, whereby the spans416,418 have any other suitable shape, whichdeviates from the shape shown in the figures.20

[071] 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 two parallel legs 512, 514 extending 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 25 512, 514 on their outward-facing side form a fastening surface for attaching the fastening profile to a building structure, such as a wall or any 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 base 510extends according to or nearly according to the width directionBeneathbothlegs512,514extend30 according to or nearly according to the transverse directionD. BE2025 / 5030 19

[072] As can be seen, 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.

[073] The first coupling part610 of the first coupling600 contains, as shown in the cross-section from Figure 3 to Figure 5, a projection that extends in one direction away from the plane V of the screen20 from the first leg412 of the U-shaped part410 of the removable profile400. 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 screen20 from the first leg512 of the mounting profile500. It is clear, as shown in Figure 5, that in the mounted state, the first coupling part610 leans against the second coupling part10 620 and is located between the second coupling part620 and the base510 of the mounting profile500. It is clear that in this way the first coupling600 is in the mounted state ina coupled state is in which the first coupling600 prevents a displacement of the removable profile400 in the direction of the transverse direction D away from the bottom510 of the mounting profile200 at the height of the first coupling600.15

[074] The first coupling part710 of the second coupling700 contains, as shown in the cross-section of 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 a direction towards the plane V of the screen20. The second coupling part720 contains, as shown in the cross-section of Figure 3 to Figure 5, a hook-shaped element20 attached to the bottom510 of the mounting profile500. This hook-shaped element contains, as shown, an end directed in a direction away from the plane V of the screen20. As shown in Figure 5, in the attached state the projection of the first coupling part 710 leans against the projection of the second coupling part 720 and the projection ofthe first coupling part 710 is positioned between the second coupling part 720 and the base 510 of the 25 fixing profile 500. Here too it is therefore clear that in this manner the second coupling 700 is in a coupled state in the fixed state, whereby the second coupling 700 prevents a displacement of the removable profile 400 in the direction of the transverse direction D away from the base 510 of the fixing profile 200 at the height of the second coupling 700.

[075] It is thus clear that in the confirmed state in Figure 5, the first coupling600 and the second coupling700 are in a coupled state and prevent a movement of the removable profile 400 with respect to the fixing profile 500 along the transverse direction D as a result of a BE2025 / 5030 20 force exerted by the screen20. As described above, it is also clear that the first coupling600 and the second coupling700 between the confirmed 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, can, from theThe confirmed state in Figure 5 and the removable state in Figure 4 can be achieved by means of a displacement of the removable profile 400 along the width direction 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 by means of a reverse displacement of the removable profile 400 relative to the fixing profile 500 from the removable state in Figure 4, the confirmed state of Figure 5 can be achieved. It is further clear 10 that in the removable state of the side guide 200 the first coupling 600 and the second coupling 700 are in a disconnected state, whereby a displacement of the removable profile 400 relative to the fixing profile 500 along the transverse direction becomes possible in order to remove the removable profile 400 from or attach it to the fixing profile as described above. 15

[076] As described above, the removable profile400 and thefastening profile 500 furthermore a locking element 800, in which, in the fastened state, a locking element 900 can be removablely installed to prevent mutual movement perpendicular to the plane V of the screen 20. In other words, the locking element 800 and the locking element 900 ensure, in the fastened state, that movement along the width direction 20 B of the removable profile 400 relative to the fastening profile 500 is prevented, whereby the first coupling 600 and the second coupling 700 are secured in the coupled state by the locking element 900 when it is inserted into either the first locking part 810 and the second locking part 820, or in other words when the first locking part 810 connects with the second locking part 820. It is clear in this regard that the first locking part 810 according to the 25 The example of execution shown is installed next to, or along, the second leg414 on the outside of the U-shaped part of the removable profile400. As can be seen further on, the second retaining part820 is attached to the bottom510 of the U-shaped according to the shown execution form.part of the fastening profile 500. 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 30 B in the fixed position as shown in the cross-section of Figure 5 BE2025 / 5030 21 for inserting 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.

[077] However, it is clear that a number of alternative designs are possible for the first coupling 600 and the second coupling 700, other than the designs shown in Figure 3 to Figure 5. According to such designs, for example, the first coupling 600 contains a first 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 perpendicular to theto move plane V of screen 20 between the fixed states and the removable state. According to such design forms, the second coupling 700 contains, for example, a first coupling part 710 attached to the removable profile 400 and a second coupling part 720 attached to the fixing profile 500. This first coupling part 710 and the second coupling part 720 are also configured to move perpendicular to the plane V of screen 20 between the fixed states and the removable state by means of mutual movement.

[078] As visible, the design of the side guide 200 shown below contains a preferred third coupling part 630 for the first coupling 600 and a third coupling part 730 for the second coupling 700 which are attached to the fastening profile 500. As will be described in detail below, this allows the removable profile 400 to be attached to the fastening profile 500 selectively, in two different orientations. A first orientation isillustrated in Figures 3 to 6. The second orientation is shown in similar 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 positioned symmetrically or nearly symmetrically with respect to a plane S centrally located 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 extends in the middle or nearly in the middle between 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 700 are also positioned symmetrically or nearly symmetrically with respect to this central plane S of the mounting profile 500. In other words, according to the shown design with respect to the plane Scentral between both legs 512, 514 of the mounting profile 500, the distance of 30 isthe second coupling part620 and the third coupling part630 of the first coupling600 are equal or nearly equal, and the distance of the second coupling part720 and the third coupling part730 of the BE2025 / 5030 22 second coupling700 is equal or nearly equal. In other words, the second coupling part620 and the third coupling part630 of the first coupling600 are located equally far or nearly equally far from this plane S, as well as that the second coupling part720 and the third coupling part730 of the second coupling700 are located equally far from this plane S. It is clear that alternative designs are possible in which the distance between the two legs of the fastening profile, for example, contains a percentage difference of 10% or less with respect to a plane S5 centrally between both legs and 512, 514 of the fastening profile 500 and the distance of the second coupling part 620 and the third coupling part 630 from the first coupling 600 and / or the distance of the second coupling part 720 and the third coupling part 730 from the second coupling 700, preferably contain a percentage difference of 5% or less.10

[079] Figures 7 to 10 show similar views to Figures 3 to 6 respectively,where only the orientation of the removable profile 400 relative to the fixing profile 500 was adjusted. As visible, the removable profile 400 was rotated 180° relative to the orientation shown in Figures 3 to 6, along 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 shown execution form, 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 such different orientations may be called the first or the second. In the first orientation, as described above, the first coupling of the removable profile contains the first coupling part attached to the removable profile 400 and the second coupling part attached to the fastening profile 500.In other words, in this orientation the first coupling600 of the removable profile400 is formed by these coupling parts610,620. As described with respect to Figure 3 to Figure 525, the first coupling part610 and the second coupling part620 of the first coupling600 are configured to move between the confirmed states and the removable state by means of mutual movement perpendicular to the plane V of the screen20.

[081] As visible in Figures 7 to 9, in the second orientation the first coupling 600 of the removable profile 400 contains the first coupling part 610 that is attached to the removable profile 400 and the third coupling part 630 that is attached to the mounting profile 500. In other words, in this orientation the first coupling 600 of the removable profile 400 BE2025 / 5030 23 is formed by this same coupling part 610 of the removable profile 400 as in the first orientation, but with a different coupling part 630 of the mounting profile 500 in the second orientation. As shown in Figures 8 and 9, the first coupling part 610 and theThe second coupling part of the very first coupling can also be configured by means of mutual movement perpendicular to the plane V of the screen between the fixed state of Figure 5 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 fixing profile 500 for moving the removable state to the fixed state, and a movement to the right for the reverse movement. This is in contrast to a movement to the right of the removable profile 400 relative to the fixing profile 500 for moving 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.

[082] Similar to the first coupling described above, 600 also contain the 15second coupling700the possibility to be used in a second orientation of the removable profile400 relative to the mounting profile500. In the first orientation of the removable profile, the second coupling700contains the first coupling part710 which is attached to the removable profile400 and the second coupling part720 which is attached to the mounting profile500. In addition, as described above, the first20 coupling part710 and the second coupling part720 are configured to move between the attached state and the removable state by means of mutual movement perpendicular to the plane V of the screen20, as shown in Figure 4 and Figure 5.

[083] In the second orientation of the removable profile400, the second coupling700 also contains the first coupling part710 attached to the removable profile400, but25 unlike in the first orientation, the second coupling700 contains the third coupling part730 attached to the mounting profile500. As can be seen, the first coupling part710 is included.the third coupling part730 be configured to move perpendicular to the plane V of the screen20 between the fixed states and the removable state by means of mutual movement. Similar to what is described above with regard to the first coupling600, 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 fixed state in Figure 9.

[084] Additionally, it is clear that the safeguard 800 and the safeguard element 900 are installed according to the execution example shown 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 10.5 However, it is clear that alternative execution forms are possible in which the safeguard 800 and the safeguard element 900 are installed at other suitable locations and / or in which use is made of a third coupling part in a similar manner as described aboveis mounted symmetrically or nearly symmetrically with respect to the central fin S with the second locking part 820 to enable locking in the two orientations of the removable profile 40010.

[085] It is clear, however, that many other designs are possible, in which the removable profile 400 is configured to be mounted, selectively, in two different orientations to the mounting profile 500. As explained in, for example, Figure 6 and Figure 10, such flexibility is advantageous for realizing with the same profiles and a side guide 20015 the plane of the screen 20 can be mounted 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 mounted in the desired orientation on the mounting profile.

[086] Furthermore, it is clear that the removable profile400 on both sides of the U-shaped part20preferably 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 900.25

[087] 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 side guide200 with a U-shaped fastening profile500, a design similar to that shown in Figure 11 to Figure 13 is used. Similar elements were indicated with similar references and contain a similar structure and functional30 characteristics as described above. Figures 11 to 13 show similar states as shown in Figures 3 to 5, in other words a removed state, a BE2025 / 5030 25removable conditions and a fixed condition. This version differed from the version described above in the fact that the fixing profile 500 next to the bottom 510 perpendicular to the plane V of the screen 20 contains only one leg 512 that extends from the bottom 510 along the plane V of the screen 20. In other words, the fixing profile 500 contains an L-shaped cross-section instead of a U-shaped cross-section. Such a profile 5 offers the advantage that it can be executed more compactly along the width direction B. However, the flexibility to apply the removable profile400 in two different orientations to the fixing profile500 is not present here. It is, however, possible to use the removable profile400 of this design with the fixing profile500 of the design shown in Figure 1 to Figure 10, as shown in Figure 14, for example. Such a design is advantageous, for instance, when minimal space is desired between the removable profile400 and the leg of the U-shaped structure.to attach another element to the 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 screen20 that is rollable up and down in the removable profile400 as described above. It is clear that a number of alternative configurations are possible. It is further clear that, in the configuration shown in Figure 14, the removable profile400 can also be mounted in two different orientations on the U-shaped mounting profile500. In this way, maximum flexibility for the manufacture and assembly of side guides200 can be realized with a minimum of different profiles20 400, 500. It is clear that in both configurations, the same or a similar configuration of a screen profile300 can be used.

[088] As further visible in, for example, Figure 1, Figure 6 and Figure 10, the design of the screen device 10 also contained a winding device 100 for winding upthe screen20on a winding shaft110. As visible, the winding device100 is mounted at the top of two25 side guides200, also known as a vertical installation. The schematically shown winding device100 is executed similarly to the winding device100 known from EP3372773, which is included here by reference. Similar to what is 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 mounted on the head sides, also known as the outer ends, of the 30 winding shaft110 and can be attached to a fastening body of the inner space of the housing of the winding device100 via a vertical movement. BE2025 / 5030 26

[089] These steps for a specific implementation method for assembling or disassembling the screen device10 are illustrated using Figure 15 to Figure 22. Although this method is advantageous in combination with the implementation forms of the side guides as described above, it is clear that according to another aspect the shownscreen device and the associated method for mounting and dismounting which makes use of the described rolling device100 and removable locking elements130 is also advantageous when used in combination with alternative designs of a screen device in which side guides200 are used with a removable profile400 that is removablely mounted to a fastening profile500.

[090] Figure 15 shows how a roller shaft 110 with a screen rolled up onto it and with the fastening elements 120 at its 10 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 in which the screen is not or not fully rolled onto the roller shaft 110. Next, Figure 16 shows the step in which the roller shaft 110 was secured in the roller device 100 by means of the fastening elements 120, after which, at the height of the 15 two side guides 200, a design of a locking element 130 as shown can beapplied. Figure 17 shows the step where one end 134 of the locking element 130 is inserted into a slot of 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, according to the shown design, the end 134 is inserted into a corresponding slot 104 of the housing of the winding device 20. It is clear that the cross-section of the end 134 and the corresponding slot preferably show a corresponding outline, preferably an arc-shaped or curved outline as shown, 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 25 It is clear, as for example visible in Figure 27, that in the confirmed position this side 136 clicked firmly into place against the corresponding protrusions 106 of the housing of the winding device 100. However, it is clear that a number of alternative designs are possible other than theexecution shown in Figure 27, whereby a rigid removable connection can be realized. Preferably, the connection is a snap connection.30

[091] In Figure 19, the execution form of this method for mounting the screen device10 is continued by providing a cover plate140 for the BE2025 / 5030 27 underside of the housing of the winding device110. As visible in Figure 20, according to the execution, first stone end148 of the cover plate140 is placed in a slot108 of the housing of the winding device100 as also shown in more detail in Figure 27. Next, in Figure 21, the cover plate140 is snapped onto the locking element130 by inserting the projection142 of the cover plate140 into the slot132 of the locking element130 so that a rigid5 a 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 this way.after installing the cover plate140 according to this design, the locking elements 130 can no longer be unclipped. This is only possible again after removing the cover plate140.10

[092] Finally, in a subsequent step, the removable profile140 of the side guide200 is attached to the fastening profile500 as shown in Figure22, where it is clear that in this state the locking element130, as well as the cover plate140, can no longer be removed according to this design.

[093] It is clear that the above design of the method for mounting a screen device10 also describes a design of a method for dismantling the screen device10 in which the preceding steps are performed in reverse order.

[094] It is clear that alternative embodiments are possible where the winding device 100 contains at least star height of the two side guides 200 two corresponding removable20 retaining elements 130 configured to prevent the winding shaft 110 from coming out of thethe winding device 100 can be removed. It is clear that the retaining elements 130 are configured in such a way that they can only be removed when the removable profile 400 of the corresponding side guide 200 is removed.

[095] Figure 23 shows a fragment of a cross-section through a design of the 25 winding shaft 110 with a screen rolled up onto it similar to that shown in Figure 15 to Figure 22. As can be seen, a fastening element 120 is fitted at the end of the winding 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 a movement of the fastening element 120 in the transverse direction D for 30 the removal of the winding shaft 110 from the winding device 100. In the configuration shown, two upward protrusions 131 are fitted to the locking element 130, BE2025 / 5030 28 it is however clear any suitable number, such as one or more, is possible according to alternativeversions. Figure 24, Figure 25 and Figure 26 further show this version of the locking element 130 in a side view, a top view and a perspective view. The click connection 132 for the removable attachment of the cover plate 140 is also visible. However, it is clear that a number of variant versions are possible in which the 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 removablely to the housing of the winding device 100 by means of a click connection. Preferably, the cover plate 140 is also configured to be attached removablely to the locking elements 130 by means of a click connection.

[096] According to the execution example shown in Figure 23 and Figure 27, containedThe design of the locking elements further provides a stop surface138 for the cover plate. This allows the cover plate140 to be leaned against this stop surface138 of the 15 locking elements130 for positioning the cover plate140 in the fixed state. It is further clear from Figure 23 that the design of the cover plate140 can also only be removed when the removable profile400 has been removed from the corresponding side guide200. Furthermore, the cover plate140 prevents the winding shaft110 from being removed from the winding device100 when the cover plate140 is installed. Thus, a double locking20 of the winding shaft110 is created according to this design, once by the locking elements130 and a second time by the cover plate140.

[097] Furthermore, it is also visible that according to the design shown, the retaining elements 130 contain two stop surfaces102 for corresponding stop surfaces of a bottom rail150 fitted at the bottom of the screen20. In this way, the retaining elements can prevent the bottom rail25150 would intrude into the housing of the winding device100 in an undesirable manner when the screen20 is fully rolled up. This also helps in positioning and centering the bottom bar 150 which is 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. BE2025 / 5030 29

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

[099] The above configurations are particularly advantageous when the winding device 100 is mounted in such a way that the winding shaft 110 can only be removed from the winding device 100 via the side guides 200. This is, for example, the case with configuration 5 as shown in Figure 6 and Figure 10, where the winding device 100 is, for example,installed in a cavity of a wall near a window. However, it is clear that alternative designs are possible, which is also advantageous, such as when the roller devices / or the side guides are at least partially incorporated into the plastering of a wall,….10

[100] As further shown in Figure 6 and Figure 10, support feet 160 have been installed on the underside of the side guides 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 has been installed 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 162 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 modulara foot containing two different parts162,164 is advantageous since it allows the side guide200 to be installed efficiently on a surface that may or may not have a slope. It is, however, clear that alternative designs are possible in which any suitable foot is used to achieve a good connection with the ground surface. In this respect, it is advantageous that the screen device10 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 slope164.25
