Description

Method for mounting a roller blind, in particular an insect screen, and roller blind of this type

Technical Field

The invention relates to a method for mounting a roller blind, in particular in the form of an insect screen or the like, for shielding a building aperture in an inclined wall, in particular a roof window area, the roller blind comprising a top housing, a bottom element, a first side rail and a second side rail, a mounting bracket and a shielding body, the top housing comprising: a rear surface adapted to abut the inclined wall in an installed state of the roll screen; a front surface adapted to face away from the inclined wall in the mounted state of the roll screen; and an upper surface adapted to connect the rear surface and the front surface, the mounting bracket comprising: a first leg adapted to bear against the sloped wall; a second leg extending at an angle to the first leg; and a third leg extending from the second leg either in the same direction as the first leg to form a generally U-shaped configuration or in a direction opposite the first leg to form a stylized inverted S configuration. The invention also relates to such a roller blind.

Background

When installing a roller blind of the above-mentioned type on an inclined wall, it is necessary to simultaneously hold the roller blind towards the inclined wall at the building aperture and fix the roller blind to the inclined wall. Thus, the process of holding the roller blind towards the inclined wall at the building aperture and fixing the roller blind to the inclined wall is often cumbersome and implies risks such as dropping of tools or fastening elements or even the roller blind and incorrect positioning of the roller blind on the inclined wall.

Especially in the case of roller blinds in the form of insect screens, proper positioning is important to ensure that the roller blind effectively seals a building aperture, for example, to avoid insects, e.g. mosquitoes, from entering through a small gap or opening left accidentally.

In the prior art, various devices have been proposed in an attempt to alleviate the above-mentioned problems. For example, it is known to provide a mounting bracket having a female portion and a screw lock and to provide a compensating male portion on the top housing of a roller blind. As another example, EP 1816513 A1 shows a clip for a detachable component.

However, the prior art roller blinds have the disadvantage of being excessively cumbersome and time consuming to install. Furthermore, the prior art methods pose a significant risk of misadjustment of the roller blind with respect to the building aperture it is intended to cover, for example, particularly when the adjustment is not possible once the male and female portions are engaged.

It is therefore desirable to propose an improved method of the type mentioned by way of introduction, by means of which the above drawbacks are more fully alleviated.

Disclosure of Invention

It is therefore an object of the present invention to provide an improved method of installing a roller blind for covering a building aperture in an inclined wall, such as a roof window area, by which the installation process is simplified and by which the roller blind can be adjusted relative to the inclined wall even after the roller blind has been brought into abutment with the inclined wall.

In a first aspect of the invention, the above and other objects are achieved by means of a method of the type mentioned by way of introduction, and comprising the steps of:

a) Assembling a rectangular frame comprising a top housing, a bottom member, and first and second side rails such that the top housing and bottom member extend substantially parallel to each other, and such that the first and second side rails extend substantially parallel to each other and connect the top housing and bottom member,

b) The mounting bracket is mounted on the inclined wall of the building adjacent the top inclined wall of the building aperture,

c) Engaging the top housing of the rectangular frame with the mounting bracket such that the rectangular frame is carried by the mounting bracket and allows the rectangular frame to hang freely, extending generally vertically from the mounting bracket, and

d) The rectangular frame is brought into abutment with the inclined wall along the entire periphery of the building aperture.

In this way, an improved method of installing a roller blind for shielding a building aperture in an inclined wall, such as a roof window area, is provided. This method simplifies the installation process, in particular by means of step a) described above, because the rectangular frame can be assembled, for example on the floor, before any components are mounted on the inclined wall.

Furthermore, by installing the mounting bracket in a separate step, step b), the installer may focus only on the mounting bracket during this installation step, and then engage only the assembled rectangular frame with the mounting bracket. Since the rectangular frame is allowed to hang freely on the mounting bracket, the installer can loosen the rectangular frame and access tools etc. in preparation for the subsequent step d). In particular, thanks to steps b) and c), the roller shutter can be adjusted with respect to the inclined wall even after it has been brought into abutment with the inclined wall, since the rectangular frame is fixed to the inclined wall only after step d).

In principle, the mounting bracket may have any suitable configuration that allows the assembled rectangular frame to be temporarily carried in its free hanging position after step c). The possibility of choosing the desired configuration like a U-shape or a stylized inverted S-shape provides flexibility and at the same time ensures a firm temporary engagement between the top housing and the mounting bracket in the free hanging position.

In a presently preferred embodiment, the step of abutting the rectangular frame against the inclined wall is performed by rotating the rectangular frame about an axis defined by the mounting bracket. Alternatively or additionally, the step of abutting the rectangular frame against the inclined wall may be performed by subjecting the rectangular frame to a rotational movement, such as to abut the bottom element against the inclined wall. Thus, a particularly simple installation method is provided.

In another embodiment, the method comprises the further steps of: the rectangular frame is fixed to the inclined wall by means of fastening elements. Depending on the type of material in the inclined wall, many variants of fastening elements, such as screws, are available and the fastening operation can be performed relatively easily to provide a reliable fastening.

In another presently preferred embodiment, the base member includes an opening adapted to receive the fastening member, and the method includes the further steps of: the rectangular frame is fixed to the inclined wall by temporarily fixing the bottom element to the inclined wall in a first, intermediate position by means of fastening elements, and then in a second, final position. Making an opening in the bottom element facilitates the mounting process.

In a further development of this embodiment, the opening is an elongated opening, and the method comprises the further step of: the lateral position of the bottom element and the top housing is adjusted by fixing the rectangular frame to the inclined wall by temporarily fixing the bottom element to the inclined wall by means of fastening elements in a first, intermediate position, and the position of the bottom element and the top housing relative to the inclined wall in a second, final position. Providing an elongated opening further facilitates the installation process. Thus, a method is provided by which a firm and correct mounting of the roller blind on the inclined wall is provided such that no gaps or openings are accidentally left. In particular, by providing an elongated hole in the bottom element, the lateral position of the bottom element can be adjusted before fixing the position of the bottom element relative to the inclined wall. Thereby, even in the case of building apertures having a cross section deviating from a perfect rectangle, which is the case in practice, a correct positioning of the roller blind is ensured.

In an embodiment, at least one of the side elements comprises an opening adapted to receive another fastening element, and the step of fixing the rectangular frame to the inclined wall comprises fixing the side element to the inclined wall by means of the other fastening element. Thereby, a more secure mounting of the roller blind on the inclined wall is provided. Advantageously, the step of engaging the top housing of the rectangular frame with the mounting bracket comprises the step of engaging a rear surface of the top housing with at least the third leg of the mounting bracket. The engagement may alternatively be at the upper surface of the top housing; however, this will make it more difficult to conceal the parts needed to achieve the joint.

In a presently preferred further development of this embodiment, a rail is provided on the rear surface of the top housing and extends adjacent the upper surface of the top housing in the longitudinal direction of the rear surface of the top housing, and the second and third legs of the mounting bracket and the rail of the top housing are adapted to be in locking engagement with each other. This provides a further simplified and secure process of mounting the roller shutter on the inclined wall, as this thereby avoids an unintentional disengagement of the roller shutter and the mounting bracket during the mounting process. Thus, in the step of engaging the assembled rectangular frame with the mounting bracket, the frame is held at an angle away from the inclined inner wall, except vertically, and once engagement has been established and the rectangular frame is allowed to hang freely, the frame cannot be retracted without rotating the frame.

In a further development of this embodiment, the second leg and the third leg extend at an angle β relative to each other, the angle β being between 90 degrees and 110 degrees, in particular approximately 100 degrees. This provides a particularly simple locking of the top housing to the mounting bracket during mounting and also provides a rational and efficient mounting procedure.

In an embodiment, the second leg comprises a first width measured as the shortest extension of the second leg between the first leg and the second leg, and the third leg comprises a second width measured as the extension of the third leg from the second leg to the opposite free edge, the track comprising: a first metric measured as the shortest distance between the lower edge and the upper edge of the rail; a second measure measured as the shortest distance of the lower edge of the rail to the inner surface of the upper surface of the top housing facing the interior of the top housing; and a third measure measured as a distance between an upper edge of the rail and a transition between a lower edge of the rail and the rear surface of the top housing, the first measure, the second measure, the first width, and the second width being generally sized relative to one another such that the top housing and the mounting bracket can be released from one another when the rear surface of the top housing and the first leg of the mounting bracket are disposed at a first angle relative to one another, and such that the top housing and the mounting bracket lock with one another when the rear surface of the top housing and the first leg of the mounting bracket are disposed at a second angle relative to one another, and the first angle is greater than the second angle. Hereby, a track with a particularly simple structure is provided which enables to obtain a favourable locking engagement with each other and thus a top housing and eventually a roller blind.

In an embodiment, the first angle is greater than 35 degrees and the second angle is less than 15 degrees. Such values of the first angle and the second angle have proven to be particularly useful in connection with the tilting of the usual tilting walls.

In an embodiment, the first width is greater than the first metric and less than the second metric.

In an embodiment, the second width is greater than the third measure. Thereby, not only an advantageous locking engagement is provided in a particularly simple manner structurally but also in view of ensuring that said engagement is obtained during the mounting process.

In principle, the mounting bracket may be formed in any suitable manner that allows the assembled frame to be carried by the mounting bracket after the step of engaging. In a presently preferred embodiment, the third leg of the mounting bracket is provided with a free edge opposite the second leg configured to engage a portion of the top housing, the free edge preferably conforming in shape to the shape of the portion of the top housing, more preferably having a rounded shape to interact with the rounded portion of the top housing.

In a development of this presently preferred embodiment, the top housing comprises a delimiting part adapted to delimit the opening of the track, the mounting bracket comprises a hook-shaped part arranged at a free edge of the second leg opposite the third leg, and the hook-shaped part is adapted to engage with the delimiting part. Thereby, an even simpler and safer locking engagement is provided to at the same time further ensure that accidental disengagement of the roller blind and the mounting bracket during the mounting process is avoided. In such an embodiment, in which the free edge of the third leg of the mounting bracket and the relevant portion of the top housing are adapted to each other, in particular in case both of them have a rounded shape, a rotational movement of bringing the assembled rectangular frame hanging vertically from the mounting bracket to an inclined position substantially parallel to the inner wall is facilitated.

In an embodiment, the side rails include extension elements, and the assembling step includes assembling the rectangular frame with the top housing, the bottom element, the first side rail and the second side rail, and the extension elements such that the top housing and the bottom element extend substantially parallel to each other, and such that the first side rail and the second side rail extend substantially parallel to each other with the extension elements and connect the top housing and the bottom element. Such an extension element provides a simple and effective way of adapting the dimensions of the rectangular frame to the dimensions of a building aperture or roof window in the field.

In a second aspect of the invention, the above and other advantages are also obtained by means of a roller blind, in particular in the form of an insect screen or the like, for shielding a building aperture in an inclined wall, in particular a roof window area, the roller blind comprising a top housing, a bottom element, a first side rail and a second side rail, a mounting bracket and a curtain, wherein the top housing, the bottom element and the first side rail and the second side rail are configured to be assembled into a rectangular frame such that the top housing and the bottom element extend substantially parallel to each other and such that the first side rail and the second side rail extend substantially parallel to each other and connect the top housing and the bottom housing. The mounting bracket includes: a first leg configured to abut the sloped wall; a second leg extending parallel to the first leg; and a third leg extending perpendicular to and connecting the first and second legs, the top housing comprising: a rear surface configured to abut the inclined wall in an installed state of the roll screen; a front surface configured to face away from the inclined wall in an installed state of the roll screen; an upper surface configured to connect the rear surface and the front surface; and a rail disposed on the rear surface and extending in a longitudinal direction of the rear surface adjacent the upper surface, and the second and third legs of the mounting bracket and the rail of the top housing are configured to lockingly engage one another.

Other presently preferred embodiments and other advantages will be apparent from the following detailed description and the accompanying drawings.

Features described in relation to one of the aspects may also be incorporated into the other aspects, and the advantages of the features apply to all of the aspects into which they are incorporated.

Detailed Description

In the following detailed description, preferred embodiments of the present invention will be described. However, it is to be understood that features of different embodiments can be interchanged between implementations and combined in different ways unless specifically indicated otherwise. It may also be noted that, for clarity, the dimensions of some of the components illustrated in the figures may differ from the corresponding dimensions in an actual implementation.

It is noted that terms such as "upper", "lower", "left hand", "right hand", "outer", "inner" are relative and refer to the perspective in question.

Referring initially to fig. 1, there is shown a first embodiment of a screening arrangement in the form of a roller blind 1 mounted at a building aperture 3 in an inclined wall 35.

The roll screen 1 may be in the form of an insect screen or the like. The roller blind 1 may be used for shielding window areas or inclined walls in building apertures 3, in particular inclined walls. The building aperture 3 is delimited by inclined walls 31 and 32, an upper inclined wall 33 and a lower inclined wall 34, and the roll screen 1 is mounted on the inside of the building aperture 3 on the inclined wall 35. The periphery is defined by the surface portions of the inclined walls 35, i.e. the periphery extends in a plane substantially perpendicular to the inclined walls 31, 32, the upper inclined wall 33 and the lower inclined wall 34.

The roller blind 1 may also be mounted directly on the sash 21 of a roof window 2, which roof window 2 is mounted on a building aperture 3. The sash 21 comprises a side element 22, a top element 23 and a bottom element 24, and the roll-up screen 1 is mounted on the inside of the sash 21, the inside of the sash 21 facing the interior of the building where the roof window 2 is mounted.

The roll screen 1 includes a supply state and a use state. Referring also to fig. 2, the roller blind 1 further comprises a top housing 4, a bottom element 5, and a first side rail 6 and a second side rail 7. In the assembled state, as shown in fig. 1, the top housing 4, the bottom element 5 and the first and second side rails 6, 7 form a rectangular frame, wherein the top housing 4 and the bottom element 5 extend substantially parallel to each other in a first longitudinal direction defining a width direction in the use state, and wherein the first and second side rails 6, 7 extend substantially parallel to each other in a second longitudinal direction defining a height direction in the use state. The first longitudinal direction is substantially perpendicular to the second longitudinal direction. Thus, the first side rail 6 and the second side rail 7 are connected with the top housing 4 and the bottom element 5. The rectangular frame thus formed defines the aperture 100. Further, the roll screen 1 may include a connecting element or insert 40 configured to connect the top housing to the side rail and a corner connecting element or insert 60 configured to connect the bottom element to the side rail.

The roller blind 1 may further comprise an extension element 8 for the first side rail 6 and an extension element 9 for the second side rail 7. The extension elements 8, 9 may extend the side rails 6, 7, for example to fit the size of the roller blind 1 with the building aperture 3 or the roof window 2 during installation. The roller blind 1 may also comprise other connecting elements or inserts, similar to the connecting element 40, configured for connecting the side rail and the extension element.

The top housing 4, the bottom element 5, the side rails 6, 7 and the extension elements 8, 9, if provided, are intended to be arranged along the edges of the building aperture 3 or along the edges of the sash 21 of the roof window 2. At the bottom of each rail of the side rails 6, 7, a breakable locking means for engagement with the holder means may be provided.

The roller blind 1 further comprises a shielding body in the form of a lightweight flexible curtain 10 which can be made of a wire mesh 15. The curtain made of the screen 15 is the following insect screen: the insect screen is adapted to cover the aperture of the window to prevent insects, leaves, debris, birds, etc. from entering the building while allowing fresh air to flow into the building. The curtain made of the wire mesh 15 may be a wire mesh, glass fibers in a net shape and similar synthetic fibers, or a plastic mesh made of polypropylene, polyethylene, nylon, PVC or PTFE or similar materials. Preferably, the curtain made of the wire mesh 15 is a PVC coated insect screen made of glass fibers. In order to facilitate handling of the roller blind in the storage state, the curtain made of the wire mesh 15 is preferably made flexible so that it can be rolled up for easy handling during storage in the season or in the supply state of the roller blind 1. The side edges of the curtain 10 are guided in tracks (not shown in detail) in the side rails 6, 7 and in the presence of the extension elements 8, 9 in tracks in the extension elements 8, 9. Thus, the curtain 10 made of the wire mesh 15 completely covers the aperture 100 of the rectangular frame in the use state.

The roller blind 1 further comprises a spring-biased roller bar 12 (see fig. 4) arranged in the top housing 4. The top housing 4 and the roll bar 12 will be mounted at the upper edge of the building aperture 3 or roof window 2.

A bottom bar 13 is arranged at the bottom edge 11 of the flexible curtain 10. The flexible curtain 10 is designed to be wound from a shade position to a non-shade position and unwound from a non-shade position to a shade position by winding the flexible curtain 10 onto the roller bar 12 or unwinding the flexible curtain 10 onto the roller bar 12, respectively. The bottom bar 13 comprises at its opposite ends guide members slidable in the guide rails of the side rails 6, 7. The bottom bar 13 comprises a handle portion 14 intended to be gripped by a user when operating the roll screen 1. Although not described in detail herein, the handle portion 14 is provided in the form of a longitudinal recess in the bottom bar 13 to allow a user to put in a finger to operate the shielding device 1.

Referring also to fig. 3, the bottom element 5 further comprises openings 18 for receiving fastening elements 19, such as screws, for fixing the bottom element 5 to the inclined wall 35. The bottom element 5 is temporarily fixed to the inclined wall 35 in a first, intermediate position. After the lateral adjustment of the bottom element 5 and the top housing 4 such that the rectangular shape is maintained, the bottom element 5 and thus the top housing are fixed in the second, final position. The opening 18 is the following elongated opening: the elongated opening allows for adjustment of the lateral position of the assembled rectangular frame before the fastening element 19 is fully fastened and thus the position of the bottom element 5 and other components relative to the inclined wall 35 is fixed. Alternatively, the opening 18 may be a rounded opening.

Furthermore, at least one of the side elements 6 and 7 may in a similar way comprise an opening for receiving another fastening element to secure the side element 6, 7 to the inclined wall 35. In addition, the extension elements 8, 9 may also comprise such openings, if provided.

Referring now to fig. 4, top housing 4 includes a rear surface 41, a front surface 42, and an upper surface 43. The rear surface 41 abuts against the inclined wall 35 in the mounted state of the roll screen 1. The front surface 42 faces away from the inclined wall 35 in the mounted state of the roll screen 1. Upper surface 43 connects rear surface 41 and front surface 42. The top housing 4 defines an interior 49 that accommodates the roll bar 12. The flexible curtain 10 is located at one end portion connected to the rolling rod 12 and wound on the rolling rod 12 such that a majority of the flexible curtain 10 is also contained in the top housing 4 in the non-blocking position. Fig. 4 is a simplified diagram, not showing the connection of the flexible curtain 10 to the bottom bar 13. The opening 48 allows the flexible curtain 10 to be inserted into the interior 49 of the top housing 4.

In the illustrated embodiment, top housing 4 further includes a track 44 disposed in rear surface 41 of top housing 4 in a position adjacent, near, or near upper surface 43 of top housing 4. The track 44 is adapted to receive a portion of the mounting bracket 16 as will be described further below. The rail 44 extends in the longitudinal direction of the top housing 4 between opposite longitudinal ends 47a and 47b (fig. 2) of the top housing 4. The track 44 may extend all or part way between the opposite longitudinal ends 47a and 47b of the top housing 4, preferably centrally between the opposite longitudinal ends 47a and 47b of the top housing 4.

Referring also to fig. 5, the track 44 includes: a first metric d1, the first metric d1 measured as the shortest distance between the lower edge 441 and the upper edge 443 of the track 44; a second measure d2, the second measure d2 being measured as the shortest distance of the lower edge 441 of the rail 44 to the inner surface 444 of the upper surface 43 of the top housing 4; and a third measure d3, the third measure d3 being measured as the distance between the upper edge 443 of the rail 44 and the transition 442 or edge between the lower edge 441 of the rail 44 and the rear surface 41 of the top housing 4. The gap between the lower edge 441 and the upper edge 443 of the rail 44 forms an outwardly facing opening 445 of the rail 44. The top housing 4 may also include a bounding portion 45 bounding an opening 445 of the track 44. In addition, elements 446, such as inclined wall elements or seals, may be provided in order to delimit the track 44 towards the remaining interior 49 of the top housing 4. Furthermore, optional elements 46, such as foam edging or foam pillows, may be provided for supporting the top housing 4 against the inclined wall 35.

The roll screen 1 further comprises a mounting bracket 16. The mounting bracket 16 includes: a first leg 161, the first leg 161 being adapted to abut the inclined wall 35; a second leg 162, the second leg 162 extending perpendicular to the first leg 161; and a third leg 163 extending from the second leg 162 opposite the first leg 161 and away from the first leg 161. The mounting bracket 16 may also include a hook portion 164 disposed at a free edge 165 of the third leg 163 opposite the second leg 162. The hook portion 164 is adapted to engage with the defined portion 45 of the top housing 4. The first leg 161 may include an aperture 166 for the fastening element 17.

Generally, the second and third legs 162, 163 of the mounting bracket 16 and the track 44 of the top housing 4 are adapted to engage one another. More particularly, the mounting bracket 16 is adapted for locking engagement with the track 44.

As can be seen in fig. 4, the second leg 162 includes a first width W1, which first width W1 is measured as the shortest extension of the second leg 162 between the first leg 161 and the third leg 163. The third leg 163 includes a second width W2, which second width W2 is measured as the extension of the third leg 163 from the second leg 162 to the opposite free edge 165 of the third leg 163. The free edge 165 opposite the second leg 162 may in principle be configured to engage any portion of the top housing 4. To ensure a satisfactory engagement, the shape of the free edge 165 is preferably adapted to the shape of the relevant portion of the top housing 4. As shown, the free edge 165 has a rounded shape, defined herein as the diameter D164 of the hook portion 164, to interact with the rounded portion of the top housing 4.

The second leg 162 and the third leg 163 extend at an angle β relative to each other. The angle β is between 90 and 110 degrees, in particular approximately 100 degrees.

The first metric D1, the second metric D2, the first width W1, and the second width W2 are generally sized relative to one another such that the top housing 4 and the mounting bracket 16 may be released from one another when the rear surface 41 of the top housing 4 and the first leg 161 of the mounting bracket 16 are disposed at a first angle θ1 (fig. 6) relative to one another, and such that the top housing 4 and the mounting bracket 16 are locked to one another when the rear surface 41 of the top housing 4 and the first leg 161 of the mounting bracket 16 are disposed at a second angle θ2 (fig. 7) relative to one another. Typically, the first angle θ1 is greater than the second angle θ2. In the illustrated embodiment, the first angle θ1 is typically 35 degrees or greater and the second angle θ2 is 15 degrees or less.

Typically, the first width W1 is greater than the first measure d1 and less than the second measure d2. In addition, the second width W2 is greater than the third metric d3.

Referring now to fig. 6 to 10, a method for mounting the roll screen according to the present invention on the building aperture 3 will be described. The same method can be used in case the roller blind 1 is instead mounted directly on the sash 21 of the window 2.

In a first step, a rectangular frame (see fig. 1 and 2) comprising the top case 4, the bottom member 5, and the first and second side rails 6, 7 is mounted such that the top case 4 and the bottom member 5 extend substantially parallel to each other, and such that the first and second side rails 6, 7 extend substantially parallel to each other and connect the top case 4 with the bottom member 5. If an extension element 8, 9 is provided, the rectangular frame is assembled to further comprise the extension element 8, 9 such that the extension element 8, 9 is arranged to extend the side rail 6, 7 and parallel to the side rail 6, 7.

The rectangular frame may also be described such that in a first step the top shell 4, the bottom element 5 and the first and second side rails 6, 7 are assembled into a rectangular frame such that the top shell 4 and the bottom element 5 extend substantially parallel to each other in a first longitudinal direction defining the width direction and such that the first and second side rails 6, 7 extend substantially parallel to each other in a second longitudinal direction defining the height direction, wherein the first longitudinal direction is substantially perpendicular to the second longitudinal direction.

In a second step (fig. 6), the mounting bracket 16 is mounted on the inclined wall 35 of the building adjacent to the top inclined wall 33 (fig. 1) of the building aperture 3. This may be achieved by inserting a fastening element 17, such as a screw, through the hole 166 (fig. 4) into the first leg 161 (fig. 4) of the mounting bracket 16.

In a third step (fig. 7), the rectangular frame is engaged with the mounting bracket 16 such that the rectangular frame extends vertically from the mounting bracket 16.

To achieve this, the rectangular frame is first held at a first angle θ1 (fig. 6) to the first leg 161 of the mounting bracket 16. The third leg 163 and the hook-shaped element 164, if provided, are then inserted through the opening 445 into the track 44 of the top housing 4. The rectangular frame is then extended at a second angle θ2 (fig. 7) to the first leg 161 of the mounting bracket 16, such as also extending vertically from the mounting bracket 16. The top housing 4 and thus the rectangular frame and the mounting bracket 16 are now locked to each other. In other words, the assembled rectangular frame is engaged with the mounting bracket by holding the frame at an angle away from the sloped inner wall in addition to being vertical. Once engagement has been established and the rectangular frame is allowed to hang freely, the frame cannot be retracted without rotating the frame. If disengagement is desired, the rectangular frame is rotated back to its inserted position and lifted out of engagement with the mounting bracket.

In a fourth step (fig. 8), the rectangular frame abuts the inclined wall 35 along the entire periphery of the building aperture 3. The term "along the entire periphery" in combination with the inclined wall 35 refers to a surface that is substantially parallel to the general plane of the inclined wall 35 and the general plane of the shutter body in its shutter position, i.e., the general plane of the flexible curtain 10.

The fourth step may be performed by rotating the rectangular frame about an axis defined by the mounting bracket 16, and in particular by the second leg 162 (fig. 4) of the mounting bracket 16 and/or by abutting the bottom element 5 with the inclined wall 35 by means of a rotational movement of the rectangular frame.

The rectangular frame can then be fixed to the inclined wall 35 by means of fastening elements 19 passing through holes 18 in the bottom element 5. Similarly, fastening elements may optionally also be used to secure the side rails 6, 7 and/or the extension elements 8, 9 to the inclined wall 35. Typically, such fastening elements comprise screws adapted for the inner wall material.

In addition, when the opening 18 provided in the bottom element 5 is an elongated opening, a further step of adjusting the lateral position of the frame element may be performed before the bottom element is finally fixed in place on the inclined wall 35.

Finally, turning to fig. 9 and 10, the top housing 4 of the roll screen 1 is shown in its mounted state on the inclined wall 35. Other parts of the roll screen 1 are not shown for ease of reading.

In the position of the top housing 4 shown in fig. 9, the free edge 165 of the third leg of the mounting bracket 16 is positioned at a distance from the delimited portion 45 of the top housing 4, whereas in the position shown in fig. 10 the free edge 165 abuts the delimited portion 45. Instead, this means that the entire top housing 4 is farther from the inner wall 35 in the position of fig. 10 than in fig. 9. Thus, unevenness of the surface of the inner wall along the periphery of the building aperture can be counteracted, as the position of the top housing 4 relative to the mounting bracket 16 can be adjusted in this way.
