Description

[0001] Screen device with a roll-up device and method for assembling and disassembling a screen device with a roll-up device

[0002] Technical domain

[0003]

[0001] The technical domain relates to screen devices for roll-up screens. Such roll-up screens comprise a screen that can be rolled up and down on a screen roller, which, for example, comprises or consists of a cloth, mesh, fabric, ... which on both sides comprises a thickening that cooperates with the screen device for guiding and tensioning the screen during rolling up and down. Furthermore, the technical domain also relates to methods for assembling and disassembling the screen device.

[0004] State of the art

[0005]

[0002] An embodiment of such a screen device is known, for example, from BE1019862. Such a screen device comprises two-piece screen guides, the parts of which are detachably connected to each other by means of a screw connection and a hook-in connection. This is, for example, advantageous for assembling and / or disassembling the screen.

[0006]

[0003] The disadvantage of such a screen device is that the load exerted by the screen, for example by wind loads, or when an object or a person hits the screen, are mainly absorbed by the screw connection. This gives rise to the following disadvantages. A high-strength screw connection should be used. Great care must be taken when applying the screw connection. After installation, the screw connection is subjected to varying conditions in terms of temperature, load, etc., which can have a negative effect on the quality of the screw connection or contribute to the partial loosening of the screw connection.

[0007]

[0004] Furthermore, in the embodiment of BE1019862, the forces generated at the front of the screen and the forces at the rear of the screen act on a different part of the two-part screen guides. This has the disadvantage that the two parts must be attached to each other with great precision and that the tolerances of both parts of the screen guides must be kept very limited.

[0008]

[0005] Furthermore, there is little flexibility when installing the two-piece screen guides in relation to the plane of, for example, the window, door, etc. where they are installed. Once the first part of the screen guide has been installed, the orientation of the second part is fixed. Great care must therefore be taken to ensure that the first part of the screen guides of the screen device is positioned correctly in relation to the plane of the window, door, etc. where they are to be installed.

[0009]

[0006] Additionally, it is advantageous if the screen device allows the screen to be removed from the screen device in the direction of the screen guides. This is particularly advantageous when, for example, the roll-up device for the screen is installed in such a way that this is the only direction in which the rolled-up screen can be removed, such as when the roll-up device is mounted in acavity or behind another permanent structure of the building near an opening for a door, window, etc.

[0010]

[0007] Furthermore, the roll-up device is also exposed to these forces acting on the screen and there is a need for a roll-up device of which the roll-up shaft for the screen can be assembled and disassembled in a simple and efficient manner, and which can withstand such loads in a robust and reliable manner.

[0011]

[0008] There is therefore a need for a screen device that overcomes the aforementioned disadvantages and at the same time offers greater flexibility, is easier to assemble and disassemble, can withstand a greater load, and / or can withstand a load more reliably.

[0039] - attaching the roll-up device to a building so that the roll-up shaft can only be removed from the roll-up device via the side guides.

[0040]

[0022] According to a following aspect, a screen device is provided for a screen which can be rolled up and down in a longitudinal direction and which has a corresponding thickening along two sides which are opposite in a transverse direction, the screen device comprising two elongated side guides arranged to guide and hold the screen at the corresponding thickening of the two opposite sides of the screen, each of the two side guides comprising:

[0047] - in the assembled state, in a direction perpendicular to the plane of the screen, the first coupling and the second coupling are on the same side relative to the locking device.

[0048]

[0023] This creates a screen device with a minimum number of components, offering the flexibility of removing the removable profile even when the screen profile has been installed in alocation where only the side of the screen profile facing the screen is accessible. In addition, the couplings further facilitate the assembling and disassembling, as a transverse movement of the removable profile relative to the mounting profile is sufficient to move between an assembled state and a removable state of the removable profile. Furthermore, the specific location of the couplings ensures that they are positioned close to and on either side of the plane of the screen, allowing them to withstand greater loads and withstand loads more reliably. In addition, the locking device and the locking element are also at least partially shielded from the greatest load exerted on the side guide by the screen.

[0049]

[0024] According to an embodiment, a screen device is provided, wherein:

[0050] - the first coupling comprises:

[0051] - a first coupling member attached to the removable profile; and

[0067] - a second coupling member comprising or consisting of a projection extending in a direction towards the plane of the screen from a first leg of the mounting profile, wherein, in the assembled state, the first coupling member rests against the second coupling member and is located between the second coupling member and the bottom of the mounting profile; - the second coupling comprises:

[0068] - the first coupling member comprising or consisting of a hook-shaped element that is attached to the U-shaped portion of the removable profile and that contains an end that points in a direction towards the plane of the screen; and

[0069] - a second coupling member comprising or consisting of a hook-shaped element that is attached to the bottom of the mounting profile and that contains an end that points in a direction away from the plane of the screen, wherein, in the assembled state, the protrusion of the first coupling member rests against the protrusion of the second coupling member and is located between the second coupling member and the bottom of the mounting profile.

[0070]

[0027] This allows the connections to be realized using simple and reliable elements.

[0071]

[0028] According to an embodiment, a screen device is provided, wherein:

[0072] - the mounting profile comprises a U-shaped portion , wherein the U-shaped portion comprises:

[0073] - a bottom perpendicular to the plane of the screen;

[0074] - two parallel legs extending from the bottom along and on either side of the plane of the screen.

[0075]

[0029] This offers the advantage that the mounting profile can easily be attached to a building in different orientations.

[0076]

[0030] According to an embodiment, a screen device is provided, wherein the removable profile is configured to be selectively attached to the mounting profile in two different orientations.

[0077]

[0031] This creates a highly flexible screen design, in which a minimum number of profiles can be used to create a variety of desired screen profile configurations. This also ensures efficient and robust installation, particularly when, for example, the mounting profile has been installed in a hard-to-reach location or in a way that does not allow removal without damage, such as when the mounting profile is at least partially embedded in the plaster. Regardless of the orientation of the mounting profile, the removable profile can be installed in the desired orientation under such circumstances.

[0078]

[0032] According to an embodiment, a screen device is provided, wherein:

[0079] - the first coupling in a first orientation of the removable profile comprises:- a first coupling member attached to the removable profile; and

[0088] - the second coupling in the second orientation of the removable profile comprises:

[0089] - a first coupling member attached to the removable profile; and

[0090] - a third coupling member attached to the mounting profile,

[0091] wherein the first coupling member and the third coupling member are configured to move between the assembled state and the removable state by means of the relative movement perpendicular to the plane of the screen.

[0092]

[0033] This makes it easy to selectively attach the removable profile.

[0093]

[0034] According to one embodiment, a hinge assembly is provided, whereby: relative to a plane centered between both legs of the mounting profile, the distance between the second coupling member and the third coupling member of the first coupling and / or the distance between the second coupling member and the third coupling member of the second coupling:

[0094] - are equal or nearly equal;

[0095] - contain a percentage difference of 10% or less;

[0096] - contain a percentage difference of 5% or less.

[0097]

[0035] This allows the coupling members of the mounting profile for the selective mounting of the removable profile to be easily realized, which also makes it easy for an installer to carry out the mounting in both orientations, as the symmetrically arranged coupling members allow for a similar mounting in both orientations.

[0036] According to an embodiment, a screen device is provided, wherein:

[0098] - the screen device further comprises a roll-up device for rolling up the screen on a roll-up shaft, the roll-up device being removably attached at the top of the two side guides by means of assembling elements;

[0099] - the roll-up device comprises, at least at the level of the two side guides, a removable locking element configured to prevent the roll-up shaft from being removed from the roll-up device; and - the locking element is configured in such a way that it can only be removed when the removable profile of the corresponding side guide has been removed.

[0100]

[0037] In this way, the roll-up shaft and, optionally, a screen rolled up on it can be efficiently and easily installed in the roll-up device after the side guides have already been installed under the roll-up device, without the risk that, in the attached state of the side guides, in which the removable profile has also been installed, the roll-up shaft could unintentionally become detached from the roll-up device.

[0101]

[0038] According to an embodiment, a screen device is provided, wherein the roll-up device is attached to a building in such a way that the roll-up shaft can only be removed from the roll-up device via the side guides.

[0102]

[0039] This is particularly advantageous when it is desirable, for example, to install the roll-up device in a cavity in a wall, or in or behind a permanent structure of a building, such as a plaster layer, wherein only the underside of the roll-up device is still accessible for installing and / or removing the roll-up shaft for the screen.

[0103]

[0104] - by means of a mutual movement perpendicular to the plane of the screen, moving the removable profile and the mounting profile between an assembled state and a removable position.

[0105]

[0041] This allows for efficient, robust and simple assembling and disassembling of the screen device, even when the mounting profile is permanently attached to a building or structure or is located in a place that is difficult to remove.

[0106]

[0042] According to an embodiment, a method is provided, wherein the method comprises the following step:

[0107] - in the assembled state, the removable insertion of a locking element in the locking device to prevent mutual movement perpendicular to the plane of the screen.

[0108]

[0043] This ensures that the locking element and the locking element are optimally shielded by the couplings from loads on the side guides generated by the screen.

[0044] According to an embodiment, a method is provided, wherein the method comprises the following step:

[0109] - the selective attaching of the removable profile to the mounting profile in one of two different orientations.

[0110]

[0045] This allows for efficient and robust assembling of the side guide, wherein the desired orientation of the removable profile can be achieved after attaching the mounting profile.

[0111]

[0046] According to an embodiment, a method is provided, wherein the method comprises the following steps:

[0112] - attaching the removable profile in a first orientation by:

[0113] - forming the first coupling with the first coupling member and the second coupling member of the first coupling; and

[0114] - forming the second coupling with the first coupling member and the second coupling member of the second coupling;

[0115] - attaching the removable profile in a second orientation by:

[0116] - forming the first coupling with the first coupling member and the third coupling member of the first coupling; and

[0117] - forming the second coupling with the first coupling member and the third coupling member of the second coupling.

[0118]

[0047] This allows the removable profile to be easily and efficiently installed in the desired orientation.

[0122]

[0050] This method ensures efficient assembling and disassembling of the roll-up shaft reducing the risk of the roll-up shaft becoming detached when the removable profile in the assembled state is attached to the mounting profile of the side guide.

[0123]

[0051] According to an embodiment, a method is provided, wherein the method comprises the following steps:

[0124] - attaching the roll-up device to a building so that the roll-up shaft can only be removed from the roll-up device via the side guides.

[0125]

[0052] The method is particularly advantageous in such circumstances where the roll-up shaft can only be attached to or removed from the roll-up device in this manner.

[0053] It is understood that the above-mentioned embodiments relate to optional and / or preferred embodiments and that a variety of further variants and combinations are possible without departing from the scope of protection as determined by the claims.

[0139] Detailed description

[0140]

[0055] Figure 1 schematically shows a perspective view of an embodiment of a screen device 10. An embodiment of a screen 20 appropriate for use in a screen device 10 of Figure 1 isshown schematically in Figure 2. In the state shown in Figure 1, the screen 20 is in a rolled-up position in the roll-up device 100. As is known to a skilled person, such a screen 20 can be rolled up and down along a longitudinal direction L as indicated in Figure 1. Figure 2 shows a view along this longitudinal direction L of the embodiment of the screen 20.

[0141]

[0056] As can be seen in Figure 2, the embodiment of the screen 20 comprises a corresponding thickening 26, 28 along two sides 22, 24 which are opposite in a transverse direction D. It is clear that the transverse direction D is transverse to the longitudinal direction L, and that the transverse direction D 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 embodiments are possible for the illustrated thickening 26, 28 on each of the opposite sides 22, 24, also referred to as lateral sides, of the screen 20. The thickening may, for example, comprise or consist of half of a zipper or other suitable thickening attached to or on the screen along the sides 22, 24. It is also clear that this thickening 26, 28 extends along the longitudinal direction L along the respective sides 22, 24 in the unrolled state of the screen 20. In addition, according to certain embodiments, the thickening may extend over the entire length of the screen 20, but alternative embodiments are possible in which the thickening is only provided on a part of the length of the screen 20 and / or is provided on the screen according to a specific pattern, for example a repetitive pattern along the longitudinal direction.

[0142]

[0057] The embodiment of the screen device 10 comprises two elongated side guides 200, only one of which is shown in Figure 1 for reasons of clarity, arranged to guide and hold the screen 20 at the corresponding thickening 26, 28 of the two opposite sides 22, 24 of the screen 20. In other words, as known to the skilled person, a side guide 200 is provided on each side 22, 24 of the screen 20. In other words, these side guides 200 are arranged along the transverse direction D on either side of the screen 20. The side guides 200 are elongated elements, also known as profiles, which extend in an elongated manner along the longitudinal direction L.

[0143]

[0058] The embodiment of the side guides 200 as shown in Figure 1 is explained in more detail with reference to 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 can be seen 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 L and the transverse direction D.

[0144]

[0059] Figures 3 to 5 show various steps of a method for assembling the embodiment of the side guide 200. Here, Figure 5 shows the assembled state of the embodiment of the side guide 200, and Figures 3 and 4 show two steps for mounting or assembling this side guide 200. It is clear that an embodiment of a method for disassembling the embodiment of the side guide 200 is also proposed when, starting from the assembled state in Figure 5, via the state in Figure 4, thedisassembled state of Figure 3 is reached. As shown in Figure 3, the side guide 200 comprises an embodiment of a screen profile 300. Such a screen profile 300 is configured to guide the thickening 26 during rolling up and down along the longitudinal direction L. As further shown, such a screen profile 300 is also configured to surround the thickening 26 of the screen 20 in order to hold the thickening 26 in the screen profile 300. As is apparent and is known to a skilled person, this can be achieved, for example, by an embodiment in which the screen profile 300 accommodates the thickening 26 in 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 is further apparent, the embodiment of the screen profile 300 may comprise a base 320 on which the slot 310 is arranged, as well as elastic elements 330 arranged between the base 320 and a removable profile 400, for example to keep the screen 20 under tension. Such elastic elements may comprise or consist of one or more suitable springs, or one or more elements of a suitable elastic or resilient material such as rubber, etc.

[0145]

[0060] It is clear that the screen profile 300 is an elongated profile that extends along the longitudinal direction L. When the screen 20 is rolled up and down, the bottom of the screen 20 thus typically moves from the top of this screen profile 300 downwards or back up to this top side. Thereby, the thickening 26 of the screen 20 slides through the screen profile 300. It is further clear that this takes place on either side of the screen 20 along the transverse direction D, in other words at the screen profiles 300 of both side guides 200 located on either side of the screen 20. In other words, by means of the screen profiles 300, the screen 20 is guided between the side profiles 200 along the longitudinal direction L and held along the transverse direction D.

[0146]

[0061] It is clear that many variant embodiments are possible than the embodiment of the screen profile 300 as shown in Figure 3. For example, variations are possible with regard to the shape and dimensions of the slot 310 and the base 320 and embodiments are possible in which, instead of and / or in addition to elastic elements 330, for example, tension elements are present such as for example mechanical, magnetic, etc. tension elements which can suitably bring and / or keep the screen 20 under tension. The screen profile 300 can be made from a suitable metal or plastic, preferably a material with a low coefficient of friction.

[0147]

[0062] Furthermore, the embodiment of the screen guide 200 shown in Figure 3 comprises a one-part removable profile 400 and a one-part mounting profile 500. This removable profile 400 is, as shown, configured to surround the screen profile 300 to retain the screen profile within the removable profile 400. The one-part mounting profile 500 is, as shown, configured for removably mounting the removable profile 400. It is further clear that the removable profile 400 and the mounting profile 500 are also elongated profiles that extend along the longitudinal direction L. Preferably, these profiles are extruded profiles from a suitable metal such as aluminium, but it isclear that alternative embodiments are possible in which the profiles are made from any suitable metal or plastic.

[0148]

[0063] As shown in Figure 3 through Figure 5, the removable profile 400 and the mounting profile 500 include and form a first coupling 600 and a second coupling 700. Figure 5 shows this first coupling 600 and second coupling 700 in an attached state. As shown in Figure 5, in this attached state, the first coupling 600 and the second coupling 700 are located on either side of the plane V of the screen 20. As is further apparent, the first coupling 600 and the second coupling 700 are further configured to move between an assembled state as shown in Figure 5 and a removable state as shown in Figure 4 by means of a mutual movement perpendicular to the plane V of the screen 20. In other words, a movement along the width direction B, in the shown orientation of Figure 5 to the left, of the removable profile 400 relative to the mounting profile 500 moves the first coupling 600 and the second coupling 700 from the assembled state shown in Figure 5 to the removable state shown in Figure 4. It is clear that in the assembled state shown in Figure 5, the removable profile 400 is removably attached to the mounting profile 500. It is also further clear that in the removable state shown in Figure 4, the removable profile 400 can be removed from the mounting profile 500, in particular by means of a movement along or approximately along the transverse direction D, so as to achieve the removed state shown in Figure 3. Conversely, it is also clear that the removable profile 400 can be inserted in the mounting profile 500, in particular by means of a movement along or approximately along the transverse direction D, so as to achieve, from the removed state shown in Figure 3, the removable state shown in Figure 4. Subsequently, for example, from the removable state of Figure 4, the assembled 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.

[0149]

[0064] As further shown in Figure 5, the removable profile 400 and the mounting profile 500 comprise and form a locking device 800. In this locking device 800, as shown in Figure 5, in the assembled state, a locking element 900 can be removably arranged. It is clear that this locking element 900 which is arranged in the locking device 800 prevents, in the assembled state, mutual movement perpendicular to the plane V of the screen 20, or in other words along the width direction B

[0150]

[0065] According to the embodiment shown, the locking element 900 is designed as a bolt 900. However, it is clear that alternative embodiments are possible, such as a screw, a pin, a snap-fit element, a clamping element, etc., which can be removably secured in the locking element 800 in the assembled state.

[0151]

[0066] According to the embodiment shown, the locking device 800 comprises a first locking member 810 and a locking retaining member 820. It is clear that the removable profile 400comprises the first locking member 810 and that the mounting profile 500 comprises the second locking member 820. The embodiment of the first locking member 810 comprises, as shown, a portion of the removable profile 400 having a surface configured to removably secure the locking element 900. In the exemplary embodiment shown, these are profiled surfaces on which the thread of the bout 900 can engage. However, it is clear that alternative embodiments are possible where alternative surfaces are possible for cooperation with alternative locking elements.

[0152]

[0067] As shown in Figure 3, in the removed state, the locking element 900 can already be arranged into the first locking part 810. According to the exemplary embodiment shown, this means that the bolt 900 is partially screwed into the first locking part 810. This is also the case in the removable position of Figure 4. As shown in Figure 4, the second locking member 820 is preferably configured such that in this removable state, the bolt 900 is prevented from extending so far out from the removable part 400 that movement along the width direction B to the assembled position in Figure 5 would be prevented. As is apparent, in this removable state of Figure 4, the second locking member 820 functions as a stop for the bolt 900, preventing any further movement of the distal end of the bolt 900 in the direction of the mounting profile 500. This allows for a displacement along the width direction B between the removable state in Figure 4 and the assembled state in Figure 5 to remain possible. As shown in Figure 5, the first locking member 810 and the second locking member 820 are aligned with each other such that the bolt 900 can be further screwed into the second locking member 820.

[0153]

[0068] As shown in Figure 6, an embodiment of the screen device 10 may comprise a plurality of such locking elements 900 disposed at various locations along the side guide 200 to secure the couplings 700, 800 of the side guide 200 in the assembled position. As shown in Figure 6, three such locking elements 900 are provided. However, it is understood that alternative embodiments are possible utilizing any other suitable number of locking elements 900 per side guide 200, such as one, two, three, four, five, or any other suitable plurality of locking elements 900.

[0154]

[0069] As shown in Figure 5, it is also clear that, according to the embodiment shown, in the assembled state, along a direction perpendicular to the plane V of the screen 20, or in other words along the width direction B, the first coupling 600 and the second coupling 700 are located on the same side with respect to the locking device 800. Or in other words, the locking device 800 is not located between the first coupling 600 and the second coupling 700 according to 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 under the influence of tension or load on the screen 20, or in other words forces, along, or largely along, the direction of the plane V of the screen 20. In this way, the locking element 900 in the locking device 800 does not haveto, or hardly has to, absorb forces in this direction, and only or mainly provides a locking function to prevent displacement along the width direction B of the removable profile 400 relative to the mounting profile 500.

[0155]

[0070] This offers the advantage that the insertion of the locking element 900 into the locking device 800 in the assembled state is less critical. Even if this connection were to degrade in the long term, or if the insertion of the locking element 900 were not carried out consistently enough when assembling, there will still be a secure connection between the removable profile 400 and the mounting profile 500 by means of the couplings 600, 700, which can reliably absorb the loads generated by the screen 20, the largest component of which extends along the plane V of the screen 20. In addition, the locking device 800 and the locking element 900 are at least partially shielded by the nearest coupling 700 from forces generated by the screen 20 acting on the side guide 200, since this coupling 700 is located between the locking device and the plane V of the screen 20 along the width direction B.

[0156]

[0071] The embodiment shown in Figures 1 to 5 shows a removable profile 400 comprising a U-shaped portion. It is thereby clear that this U-shaped second surrounds the screen profile 300. Or in other words, that the screen 20 can penetrate on the lateral side 22, 24 through the opening between the legs of the U-shaped portion into the removable profile 400. As is apparent, the U-shaped portion comprises a bottom 410 perpendicular to the plane V of the screen 20. Furthermore, the U-shaped portion also comprises 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 embodiment shown, the two legs 412, 414 are parallel or nearly parallel, as well as parallel or nearly parallel to the plane V of the screen 20. Additionally, the embodiment of the U-shaped portion also comprises two spans 416, 418 facing each other. As is apparent, these spans 416, 418 are provided at the corresponding ends of the two legs 412, 414. From there, these facing spans 416, 418 partially span the opening between the two legs 412, 414. According to the exemplary embodiment shown, as shown for example in Figure 3, these spans 416, 418 thus ensure a locking of the screen profile 300, so that the screen profile is held in the U-shaped portion of the removable profile 400 when a force with a component along the transverse direction D is exerted on it by the screen 20. As is apparent, the spans 416, 418 comprises at their ends parts which extend along the transverse direction D. These preferred parts help surround the screen profile 300, provide a stop for the maximum deflection of the screen profile 300, and also provide a suitable guide surface for a bottom slat extending transversely between both side guides 200 and, as is known to the skilled person, mounted at the bottom of the screen 20 to guide the bottom of the screen 20. However, it is understood that alternative embodiments are possible, wherein the spans 416, 418 have any other suitable shape other than that shown in the figures.

[0072] The embodiment shown in Figures 1 to 5 shows an embodiment of the mounting profile 500 comprising a U-shaped portion. The U-shaped portion of the mounting profile 500 comprises a bottom 510 perpendicular to the plane V of the screen 20. The U-shaped portion further comprises two parallel legs 512, 514 extending from the bottom 510 along and on either side of the plane V of the screen 20. It is thereby clear that the bottom 510 and the legs 512, 514 form a mounting surface on their outwardly facing side for attaching the mounting profile to a structure of a building, such as a wall or any suitable mounting surface or structure. According to the embodiment shown, it is clear that, in the cross-section as shown in Figure 3 to Figure 5, the bottom 510 extends along or nearly along the width direction B and the two legs 512, 514 extend along or nearly along the transverse direction D.

[0157]

[0073] As further shown, the embodiment of the first coupling 600 comprises a first coupling member 610 and a second coupling member 620. The second coupling 700 also comprises a first coupling member 710 and a second coupling member 720.

[0158]

[0074] The first coupling member 610 of the first coupling 600 comprises, as shown in the cross-section of Figures 3 to 5, a protrusion extending in a direction away from the plane V of the screen 20 from the first leg 412 of the U-shaped portion 410 of the removable profile 400. The second coupling member 620 comprises, as shown in the cross-section of Figures 3 to 5, a protrusion extending in a direction towards the plane V of the screen 20 from the first leg 512 of the mounting profile 500. It is clear, as shown in Figure 5, that in the assembled state, the first coupling member 610 rests against the second coupling member 620 and is located between the second coupling member 620 and the bottom 510 of the mounting profile 500. It is clear that in this manner, the first coupling 600 is, in the assembled state, in a coupled state, in which the first coupling 600 prevents displacement of the removable profile 400 in the direction of the transverse direction D away from the bottom 510 of the mounting profile 200 at the level of the first coupling 600.

[0159]

[0075] The first coupling member 710 of the second coupling 700, as shown in the crosssection of Figures 3 to 5, comprises a hook-shaped element which is arranged at the U-shaped portion 410 of the removable profile 400. This hook-shaped element, as is apparent, has an end which is oriented in a direction towards the plane V of the screen 20. The second coupling member 720, as shown in the cross-section of Figures 3 to 5, comprises a hook-shaped element which is arranged at the bottom 510 of the mounting profile 500. This hook-shaped element, as is shown, has an end which is oriented in a direction away from the plane V of the screen 20. As shown in Figure 5, in the assembled state, the protrusion of the first coupling member 710 thereby rests against the protrusion of the second coupling member 720 and the protrusion of the first coupling member 710 is located between the second coupling member 720 and the bottom 510 of themounting profile 500. Here too, it is thus clear that in this manner, the second coupling 700 is, in the assembled state, in a coupled state, in which the second coupling 700 prevents displacement of the removable profile 400 in the direction of the transverse direction D away from the bottom 10 of the mounting profile 200 at the level of the second coupling 700.

[0160]

[0076] It is thus clear that in the assembled state in Figure 5, the first coupling 600 and the second coupling 700 are in a coupled state and prevent movement of the removable profile 400 relative to the mounting profile 500 along the transverse direction D 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 can be moved between the assembled state and the removable state shown in Figure 4 by a displacement along the width direction B. In the state shown in Figures 4 and 5, from the assembled 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 in the direction away from the leg 512 of the mounting profile 500 to which the second coupling member 620 of the first coupling 600 is attached. It is clear that by a reverse displacement of the removable profile 400 relative to the mounting profile 500 from the removable state in Figure 4, the assembled state of Figure 5 can be achieved. It is further clear that in the removable state of the side guide 200, the first coupling 600 and the second coupling 700 are in a disengaged state, thereby allowing transverse displacement of the removable profile 400 relative to the mounting profile 500 so as to remove or attach the removable profile 400 from or onto the mounting profile as described above.

[0161]

[0077] As already described above, the removable profile 400 and the mounting profile 500 further form a locking device 800 in which, in the assembled state, a locking element 900 can be removably fitted to prevent mutual movement perpendicular to the plane V of the screen 20. In other words, the locking device 800 and the locking element 900 ensure, in the assembled state, that a movement along the width direction B of the removable profile 400 relative to the mounting profile 500 is prevented, whereby the first coupling 600 and the second coupling 700 are locked in the coupled state by the locking element 900 when it is inserted into both the first locking member 810 and the second locking member 820, or in other words when the first locking member 810 connects to the second locking member 820. It is thereby clear that the first locking member 810, according to the exemplary embodiment shown, is arranged next to or along the second leg 414 on the outside of the U-shaped portion of the removable profile 400. As is further apparent, the second locking member 820, according to the embodiment shown, is arranged at the bottom 510 of the U-shaped portion of the mounting profile 500. In addition, as shown in Figure 5, the position of the first locking member 810 and the second locking member 820 are configured to align with each other along the width direction B in the assembled position as shown in the cross-section of Figure5 for inserting the locking element 900 into both locking members 810, 820. It is clear that here too, alternative embodiments are possible, other than the embodiment shown in the figures.

[0162]

[0078] It is, however, clear that numerous alternative embodiments are possible for the first coupling 600 and the second coupling 700 other than the embodiment shown in Figures 3 to 5. According to such embodiments, for example, the first coupling 600 comprises a first coupling member 610 that is attached to the removable profile 400 and a second coupling member 620 that is attached to the mounting profile 500. Hereby, the first coupling member 610 and the second coupling member 620 are configured to move between the assembled state and the removable state by means of the relative movement perpendicular to the plane V of the screen 20. According to such embodiments, the second coupling 700 comprises, for example, a first coupling member 710 that is attached on the removable profile 400 and a second coupling member 720 that is attached on the mounting profile 500. This first coupling member 710 and the second coupling member 720 are thereby also configured to move between the assembled state and the removable state by means of the relative movement perpendicular to the plane V of the screen 20.

[0163]

[0079] As is apparent, the shown embodiment of the side guide 200 further preferably comprises a third coupling member 630 for the first coupling 600 and a third coupling member 730 for the second coupling 700 which are attached to the mounting profile 500. As will be described in more detail below, this allows the removable profile 400 to be selectively attached to the mounting profile 500 in two different orientations. A first orientation is illustrated in Figure 3 to Figure 6. The second orientation is shown in similar views in Figure 7 to Figure 10. In the exemplary embodiment shown, the second coupling member 620 and the third coupling member 630 of the first coupling 600 are, as can be seen, arranged symmetrically or nearly symmetrically with respect to a plane S centrally between both legs 512, 514 of the mounting profile 500. It is thereby 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. In the embodiment shown, the second coupling member 720 and the third coupling member 730 of the second coupling 700 are arranged symmetrically or nearly symmetrically with respect to this central plane S of the mounting profile 500. In other words, according to the embodiment shown, relative to the plane S centrally between both legs 512, 514 of the mounting profile 500, the distance between the second coupling member 620 and the third coupling member 630 of the first coupling 600 is equal or substantially equal, and the distance between the second coupling member 720 and the third coupling member 730 of the second coupling 700 is equal or substantially equal. In other words, the second coupling member 620 and the third coupling member 630 of the first coupling 600 are equidistant or approximately equidistant from this plane S, as well as the secondcoupling member 720 and the third coupling member 730 of the second coupling 700 are equidistant from this plane S.

[0164] It is clear that alternative embodiments are possible, in which, relative to a plane S centrally between both legs 512, 514 of the mounting profile 500, the distance between the second coupling member 620 and the third coupling member 630 of the first coupling 600 and / or the distance between the second coupling member 720 and the third coupling member 730 of the second coupling 700 comprise, for example, a percentage difference of 10% or less, preferably comprise a percentage difference of 5% or less.

[0165]

[0080] Figures 7 to 10 show similar views to Figures 3 to 6, respectively, with only the orientation of the removable profile 400 relative to the mounting profile 500 adjusted. As is apparent, the removable profile 400 has been rotated 180° about an axis parallel to the transverse direction D, relative to the orientation shown in Figures 3 to 6. It is further clear that similar elements have been designated with similar references and exhibit similar structural and functional characteristics as described above. For the embodiment shown, 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. It is clear, however, that this is merely an example, and that in any suitable way any two such different orientations may be called either the first or the second orientation.

[0166]

[0081] In the first orientation, as described above, the first coupling 600 of the removable profile 400 comprises the first coupling member 610 that is attached to the removable profile 400 and the second coupling member 620 that is attached to the mounting profile 500. In other words, in this orientation, the first coupling 600 of the removable profile 400 is formed by these coupling members 610, 620. As described with reference to Figure 3 to Figure 5, the first coupling member 610 and the second coupling member 620 of the first coupling 600 are thereby configured to move between the assembled state and the removable state by means of the relative movement perpendicular to the plane V of the screen 20.

[0167]

[0082] As shown in Figure 7 to Figure 9, in the second orientation, the first coupling 600 of the removable profile 400 comprises the first coupling member 610 that is attached to the removable profile 400 and the third coupling member 630 that is attached to the mounting profile 500. In other words, in this orientation, the first coupling 600 of the removable profile 400 is formed by this same coupling member 610 of the removable profile 400 as in the first orientation, but with a different coupling member 630 of the mounting profile 500 in the second orientation. As shown in Figure 8 and Figure 9, the first coupling member 610 and the second coupling member 620 of this first coupling are also configured to move between the assembled state of Figure 9 and the removable state of Figure 8 by means of the relative movement perpendicular to the plane V of the screen 20. It is clear that thereby, in the second orientation, the direction of movement isreversed compared to the first orientation. In other words, in the illustrated orientation of Figure 8 and Figure 9, a leftward movement of the removable profile 400 relative to the mounting profile 500 moves from the removable state to the assembled state, and a rightward movement moves the reverse movement. This contrasts with a rightward movement of the removable profile 400 relative to the mounting profile 500 for moving from the removable state to the assembled state, and a leftward movement for the reverse movement in the first orientation of Figure 5 and Figure 6.

[0168]

[0083] Similar to what is described above for the first coupling 600, the second coupling 700 also has the possibility to be utilized 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 comprises the first coupling member 710 that is attached to the removable profile 400 and the second coupling member 720 that is attached to the mounting profile 500. Hereby, as described above, the first coupling member 710 and the second coupling member 720 are configured to move between the assembled state and the removable state by means of the relative movement perpendicular to the plane V of the screen 20 as is shown in Figure 4 and Figure 5.

[0169]

[0084] In the second orientation of the removable profile 400, the second coupling 700 also comprises the first coupling member 710 that is attached to the removable profile 400, but unlike in the first orientation, the second coupling 700 comprises a third coupling member 730 that is attached to the mounting profile 500. As is apparent, the first coupling member 710 and the third coupling member 730 are thereby configured to move between the assembled state and the removable state by means of the relative movement perpendicular to the plane V of the screen 20. Similar to what is described above with respect 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 when moving between the removable state in Figure 8 and the assembled state in Figure 9.

[0170]

[0085] Additionally, it is clear that the locking device 800 and the locking element 900, according to the exemplary embodiment shown, are arranged so that they extend on or nearly on or along the plane of symmetry S in the cross-section as shown in Figure 3 to Figure 10. However, it is clear that alternative embodiments are possible in which the locking device 800 and the locking element 900 are arranged in other suitable locations and / or in which, in a manner similar to that described above, use is made of a third coupling member which is arranged symmetrically or substantially symmetrically with respect to central plane S with the second locking member 820 to enable locking in the two orientations of the removable profile 400.

[0171]

[0086] It is however clear that numerous other embodiments are possible, in which the removable profile 400 is configured to be selectively attached to the mounting profile 500 in two different orientations. As illustrated in Figure 6 and Figure 10, for example, such flexibility is advantageous in order to realize a side guide 200 using the same profiles, whereby the plane V ofthe screen 20 can be arranged at two different distances from, for example, the window. This also enhances efficiency when assembling as well as robustness, since, after assembling the mounting profile, the removable profile can always be arranged on the mounting profile in the desired orientation.

[0172]

[0087] It is further clear that the removable profile 400 preferably comprises a cover surface 420 on either side of the U-shaped portion, which forms the visible part of the removable profile 400 and which preferably extends transversely to the plane V of the screen 20 up to the ends of the legs 512, 514 of the mounting profile 500. As shown, suitable openings are preferably provided in this cover surface 420 for assembling the locking elements 900.

[0173]

[0088] However, it is clear that alternative embodiments are possible for the side guide as shown in Figure 1 to Figure 10. For example, it is possible that instead of a side guide 200 with a U-shaped mounting profile 500, an embodiment similar to that shown in Figures 11 to 13 is used. Similar elements are indicated with similar references and comprise similar structural and functional characteristics as described above. Figure 11 through Figure 13 show similar states as shown in Figure 3 to Figure 5, in other words, a removed state, a removable state, and an assembled state. However, this embodiment differs from the embodiment described above in that the mounting profile 500, in addition to the bottom 510 perpendicular to the plane V of the screen 20, comprises only one leg 512 which extends from the bottom 510 along the plane V of the screen 20. In other words, the mounting profile 500 comprises an L-shaped cross-section rather than a U-shaped cross-section. Such a profile offers the advantage that it can be made more compact along the width direction B. However, the flexibility to assemble the removable profile 400 on the mounting profile 500 in two different orientations is not present here. However, it is possible to also use the removable profile 400 of this embodiment with the mounting profile 500 of the embodiment from Figure 1 to Figure 10, as shown, for example, in Figure 14. Such an embodiment is advantageous, for example, when it is desired to arrange 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 in this space for a mosquito screen or insect screen that cannot be rolled up or down, in addition to, for example, a blackout screen 20 that can be rolled up and down in the removable profile 400 as described above. It is clear that many alternative embodiments are possible. It is further clear that also in the embodiment of Figure 14, the removable profile 400 can be arranged in two different orientations on the U-shaped mounting profile 500. In this way, maximum flexibility for manufacturing and assembling side guides 200 can be achieved with a minimum of different profiles 400, 500. It is clear that, in both embodiments, the same or similar embodiment of a screen profile 300 can be used.

[0089] As is further apparent in, for example, Figure 1, Figure 6 and Figure 10, the embodiment of the screen device 10 further also comprises a roll-up device 100 for rolling up the screen 20 on a roll-up shaft 110. As can be seen, the roll-up device 100 is thereby mounted at the top of two side guides 200, also known as a vertical installation. The schematically shown roll-up device 100 is similar in design to the roll-up device 100 known from EP3372773, which is hereby incorporated by reference. Similar to that described in EP3372773, the roll-up device 100 comprises an interior space in which the roll-up shaft 110 is removably mountable by means of assembling elements 120 which are arranged at the end faces, also known as distal ends, of the roll-up shaft 110 and can be mounted to a mounting body of the interior space of the housing of the roll-up device 100 by means of a vertical movement.

[0174]

[0090] These steps for an embodiment of a method for assembling or disassembling the screen device 10 are illustrated with reference to Figure 15 to Figure 22. While this method is advantageous in combination with the embodiments of the side guides described above, it is clear that, in another aspect, the illustrated screen device and associated method of assembling and disassembling utilizing the described roll-up device 100 and the removable lock elements 130 is also advantageous when used in combination with alternative embodiments of a screen device utilizing side guides 200 having a removable profile 400 which is removably mounted to a mounting profile 500.

[0175]

[0091] Figure 15 shows how a roll-up shaft 110 with a screen rolled up onto it and with the assembling elements 120 at its ends can be inserted into the mounting profiles 500 of the side guides 200 in order to be moved upwards towards the roll-up device 100. It is clear that alternative embodiments are possible where the screen is not or not fully rolled onto the roll-up shaft 110. Figure 16 then shows the step in which the roll-up shaft 110 has been assembled in the roll-up device 100 by means of the assembling elements 120, after which an embodiment of a lock element 130 as shown can be fitted at the height of the two side guides 200. Figure 17 shows the step in which one end 134 of the lock element 130 is inserted into a slot in the housing of the roll-up device 110. As shown in the cross-section perpendicular to the longitudinal axis of the roll-up shaft 110 of Figure 27, in the embodiment shown, the end 134 is thereby arranged in a corresponding slot 104 of the housing of the roll-up device 100. It is thereby clear that preferably the cross-section of the end 134 and the corresponding slot have a corresponding contour, preferably an arc-shaped or curved contour as shown, which facilitates tilting of the lock element 130 when assembling or disassembling. Figure 18 shows the step in which the other side 136 of the lock element 130 is snapped onto the housing of the roll-up device 100. It is clear, as can be seen for example in Figure 27, that, in the assembled position, this side 136 engages positively against corresponding projections 106 of the housing of the roll-up device 100. However, it is clear that many alternativeembodiments are possible other than the embodiment shown in Figure 27, in which a dimensionally stable removable connection can be realized. Preferably, the connection is a snap-fit connection.

[0176]

[0092] In Figure 19, the embodiment of this method for assembling the screen device 10 is continued by providing a cover plate 140 for the bottom of the housing of the roll-up device 110. As shown in Figure 20, in accordance with the embodiment, one end 148 of the cover plate 140 is first inserted into a slot 108 of the housing of the roll-up device 100, as also shown in more detail in Figure 27. Next, in Figure 21, the cover plate 140 is snapped onto the lock element 130 by inserting the projection 142 of the cover plate 140 into the slot 132 of the lock element 130 to form a dimensionally stable removable snap-fit connection. It is further appreciated that, as shown in Figure 27, in this state, the cover plate 140 prevents the lock element 130 from being removed. In this way, the cover plate 140 secures the lock elements 130. In other words, after assembling the cover plate 140 according to this embodiment, the lock elements 130 can no longer be released. This is only possible again after removing cover plate 140.

[0177]

[0093] Finally, in a next step, the removable profile 140 of the side guide 200 is arranged onto the mounting profile 500 as shown in Figure 22, it being clear that, in this state, the lock element 130, as well as the cover plate 140, can no longer be removed according to this embodiment.

[0178]

[0094] It is clear that the above-mentioned embodiment of the method for assembling a screen device 10 also describes an embodiment of a method for disassembling the screen device 10 in which the preceding steps are performed in the reverse order.

[0179]

[0095] It is clear that alternative embodiments are possible in which the roll-up device 100 comprises, at least at the level of the two side guides 200, two corresponding removable lock elements 130 which are configured to prevent the roll-up shaft 110 from being removed from the roll-up device 100. It is thereby clear that the lock 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 has been removed.

[0180]

[0096] Figure 23 shows a fragmentary cross-sectional view of an embodiment of the rollup shaft 110 with a screen rolled up there upon similar to that shown in Figures 15 to 22. As can be seen, an assembling element 120 is arranged at the end of the roll-up shaft 110, which is locked by the lock element 130 to the underside of which the cover plate 140 is arranged. As can be seen, the lock element 130 comprises upward projections 131 for realizing the locking which prevent movement of the assembling element 120 in the transverse direction D for removing the roll-up shaft 110 from the roll-up device 100. In the embodiment shown, two upward projections 131 are provided on the lock element 130, however, it is understood that any suitable number, such as one or more, is possible according to alternative embodiments. Figure 24, Figure 25 and Figure 26further show this embodiment of the lock element 130 in a side view, a top view and a perspective view. The snap-fit connection 132 for the removable assembling of the cover plate 140 is thereby also visible. However, it is clear that numerous variant embodiments are possible in which the lock element 130 is configured such that it can only be removed when the removable profile 400 of the corresponding side guide 200 has been removed and which can preferably be removably attached to the roll-up device 100 without additional assembling means. Preferably, the locking elements are configured to be removably attached to the housing of the roll-up device 100 by means of a snap-fit connection. Preferably, the cover plate is also configured to be removably attached to the lock elements 130 by means of a snap-fit connection.

[0181]

[0097] According to the exemplary embodiment shown in Figure 23 and Figure 27, the embodiment of the locking elements further comprises a contact surface 138 for the cover plate. This allows the cover platel40, in the attached state, to rest against this contact surface 138 of the lock elements 130 for positioning the cover plate 140.

[0182] It is further clear from Figure 23 that the embodiment of the cover plate 140 can also only be removed when the removable profile 400 of the corresponding side guide 200 has been removed. Furthermore, the cover plate 140 prevents the roll-up shaft 110 from being removed from the rollup device 100 when the cover plate 140 is in place. This creates a double locking of the roll-up shaft 110 according to this embodiment, once by the lock elements 130 and a second time by the coverplate 140.

[0183]

[0098] It is also apparent that, according to the embodiment shown, the lock elements 130 comprise two contact surfaces 102 for corresponding contact surfaces of a bottom slat 150 arranged at the bottom of the screen 20. Thus, the locking elements can prevent the bottom slat 150 from unintentionally entering the housing of the roll-up device 100 when the screen 20 is fully rolled up. This also aids in positioning and centering the bottom slat 150 which is arranged on the bottom of the screen 20 in the rolled-up position of the screen as shown in Figure 27. It is clear that numerous alternative embodiments are possible in which the lock elements 130 comprise at least one contact surface for a bottom slat 150 arranged at the bottom of the screen 20.

[0184]

[0099] It is further clear that the illustrated embodiment of the roll-up device 100 includes two such lock elements 130, one at each end of the roll-up shaft 110.

[0185]

[0100] The above-mentioned embodiments are particularly advantageous when the roll-up device 100 is attached to a building in such a way that the roll-up shaft 110 can only be removed from the roll-up device 100 via the side guides 200. This is, for example, the case in the embodiment shown in Figure 6 and Figure 10, in which the roll-up device 100 is arranged, for example, in a cavity of a wall near a window. However, it is clear that alternative embodiments arepossible, in which this is also advantageous, such as when the roll-up device and / or the side guides are at least partially incorporated into the plaster of a wall, etc.

[0186]

[0101] As further shown in Figure 6 and Figure 10, feet 160 are provided at the bottom of the side guides 200 of the embodiment of the screen device 10, which support the mutual alignment of both side guides 200. As can be seen, in this embodiment, a combination is provided of a foot 162 with a slope as shown in the side and top views of Figure 30 and Figure 31, and a foot 164 without a slope as shown in the side and top views 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, etc. Such a modular foot comprising two different parts 162, 164 is advantageous as it allows the side guide 200 to be efficiently assembled on a surface that may or may not have a slope. However, it is clear that alternative embodiments are possible using any suitable foot to achieve a good connection with the ground surface. In this respect it is advantageous that the screen device 10 comprises a foot 160 consisting of a selection of one or more feet 162, 164 which can be mounted together from the following combination: a sloping foot 162; and / or a foot without a slope 164.
