Description

Support for fixing a tube supporting a screen, mounting subassembly and closing and/or solar protection installation comprising such a support and associated mounting method.

The present invention relates to a support for fixing a tube supporting a closing screen or sun protection in a half-lintel and a mounting sub-assembly comprising two such fixing supports. The invention also relates to a closing or solar protection installation comprising a screen. The invention finally relates to a method for mounting such a mounting sub-assembly in a half-lintel.

It is known to install a closing or solar protection screen, such as a roller shutter, above a door or a window, the roller shutter comprising a winding tube and an apron rolled up on this tube, housed in an assembly space provided for this purpose in the masonry above the window. The apron passes through a lower slot in the half-lintel and unfolds in front of the window to hide it

For clarity, a lintel refers to a masonry unit delimiting the upper edge of an opening, such as a door or a window. In the field of construction in general and roller shutters in particular, when the lintel includes a roller shutter mounting volume open only downwards, it is called tunnel mounting. When the mounting volume is open downwards and towards the interior of the building, it is called a semi-lintel.

For reasons of comfort, particularly thermal, windows and roller shutters must have a sealed structure, which limits air infiltration.

It is known to use roller shutter systems pre-mounted in the half-lintels, these systems offering high sealing. However, to adapt to the various sizes of openings made in a wall, to provide windows or French windows, it is necessary, for each opening, to provide a pre-assembled system of the corresponding size. This multiplies the number of pre-assembled system references to be provided, which is costly. These pre-assembled systems are also difficult to open, especially in the case of maintenance operations, and to reseal once the maintenance is complete.

In addition, a half-lintel can be obtained in various ways, in particular during the construction of the building: by the use of prefabricated elements, in terracotta or concrete, or else, in the case of a concrete wall poured on site, by placing a counter-form within the wall formwork. Depending on these various construction methods, the geometry of the half-lintels may have significant dimensional deviations, due to manufacturing tolerances, in particular when the lintel is limited at the top by an element of the structural work of the building, such as a beam or a slab. The sealing between the roller shutter system and the half-lintel must be implemented on a case-by-case basis, which is time-consuming.

It is to these problems that the invention more particularly intends to remedy, by proposing a system for fixing a rolling shutter in a half-lintel, this system being easy to mount and to seal with various sizes of half-lintel, even when the half-lintel has an imperfect geometry.

To this end, the invention relates to a support for fixing at least one tube supporting a closing screen or solar protection in a half-lintel formed in a wall. The fixing support comprises a flange, which is formed in a plate defining a first plane and which comprises at least one orifice for receiving a bearing of the tube centered on a longitudinal axis which is orthogonal to the first plane. The fixing support further comprises a lower end piece, which is configured to be fixed to the wall, while the flange being fixed to the lower end piece using first reversible fixing members. According to the invention, the mounting bracket further comprises an upper end piece. The upper end piece is guided in translation with respect to the lower end piece along a deployment axis, orthogonal to the longitudinal axis, between a closed position, in which a size of the fixing support, measured parallel to the deployment axis , has a first value, and an open position, in which the space has a second value, greater than the first value.

Thanks to the invention, the roller shutter tube fixing support can be mounted in a sealed manner in the half-lintel by taking up the manufacturing clearances of the half-lintel. While the lower end piece is fixed in a side wall of the wall, the upper end piece is placed in the deployed position in contact with the beam before being fixed to the side wall. Sealing between the support and the masonry is easy to achieve, even after dismantling for a maintenance operation.

According to advantageous but not obligatory aspects of the invention, such a fixing support can also incorporate one or more of the following characteristics taken according to any technically admissible combination:

• the lower end piece has a sliding surface, while the upper end piece has a sliding wall of a shape complementary to the sliding surface, the sliding surface and wall being configured to ensure the guiding in translation of the upper end piece by relative to the lower nozzle parallel to the deployment axis.
• the sliding surface and the sliding wall are in contact with each other in a continuous contact contour, while the contact between the sliding surface and the sliding wall is sealed.
• the fixing support comprises sealing members, which provide sealing between the lower end piece and the upper end piece.
• the flange comprises guide notches, which are made in the flange along an adjustment axis orthogonal to the deployment axis, while the lower end piece comprises guide reliefs, which cooperate with the guide notches and guide in translation of the flange with respect to the lower end piece parallel to the adjustment axis.

The invention also relates to an assembly sub-assembly:

• the mounting sub-assembly comprises two mounting brackets as described previously, at least one tube which defines two ends each comprising a bearing, each bearing being received in one of the flange receiving orifices of one of the mounting brackets respective fixing, a lower profile, which connects the lower ends of the two mounting brackets together, defining a lower part of the mounting sub-assembly, an upper profile, which connects the upper ends of the two mounting brackets together, defining a upper part of the mounting sub-assembly, while the mounting sub-assembly is configured to pass from a closed configuration, in which the two upper end caps are in the closed position, to an extended configuration, in which at least one of the end caps upper is in the deployed position.
• the upper and lower sections each have an L-shape with a double branch which defines a reception volume (V100, V108) with a U-section, the reception volumes of the lower and upper sections being arranged opposite one of the other and together defining a volume for receiving a panel, the panel being able to slide in a sealed manner within the reception volumes of the upper and lower sections.

The invention further relates to a closing and/or solar protection installation, which comprises a mounting sub-assembly as described above, a wall in which an opening is formed and a half-lintel surmounting the opening, the half-lintel extending horizontally along a main axis and defining a parallelepipedal assembly volume, which is delimited in its upper part by a beam having a lower face, in its lower part by an upper upright of a carpentry frame and , on the sides, by the side walls of the wall, the upper portion of the carpentry, the side walls of the wall and the beam delimiting an access hatch of the half-lintel, while the lower part of the mounting sub-assembly is resting on the upper upright of the carpentry, the lower end pieces being fixed to the side walls of the wall, while the upper part is in the deployed configuration, the upper profile resting on the underside of the beam and the upper end pieces being fixed on the side walls of the wall, and that the panel is housed together in the reception volumes of the upper and lower profiles, closing the access door of the half-lintel in a sealed manner.

The invention finally relates to a method for mounting a mounting sub-assembly as described above:

• the method comprises the steps of:

To. insert the mounting sub-assembly into the mounting volume of the half lintel;

b. wedge the lower part of the assembly sub-assembly against the upper upright of the carpentry;

vs. fixing each of the lower half-end pieces in a respective side wall;

d. deploy the upper part of the sub-assembly by bringing the upper section into contact with the lower face of the beam;

e. fix each of the upper end caps in the side walls of the wall.

• the assembly process includes at least one preliminary step from among:

• a step consisting in adjusting, for each fixing support, the relative position of the flange with respect to the lower end piece by a translation parallel to the adjustment axis of the guide notches and then immobilizing the flange with respect to the end piece lower using fasteners and
• a step consisting of adjusting, for each fixing support, the relative position of the wedge with respect to the flange by a translation parallel to the deployment axis and then of immobilizing the wedge with respect to the flange using fasteners .

This method induces the same advantages as those mentioned above regarding the roller shutter mounting bracket of the invention.

The invention will be better understood, and other advantages thereof will appear more clearly in the light of the following description, of an embodiment of a roller shutter fixing support, of a sub- assembly comprising such a support, of a roller shutter installation comprising such a sub-assembly and of an assembly method in accordance with its principle, given solely by way of example and made with reference to the appended drawings, in which:

FIG. 1 is an exploded perspective view of a closure and solar protection installation according to the invention, comprising two tube fixing supports according to the invention;

Figure 2 is a partial section along plane II of Figure 1;

Figure 5 is a section similar to Figure 4, illustrating a second step of the mounting method;

FIG. 6 is a section similar to FIG. 4, illustrating a third step of the mounting method, and

Figure 7 is a section similar to Figure 4, illustrating a fourth step of the mounting method.

FIG. 1 represents an installation 2 for closure and solar protection in accordance with the invention. In the example of figure 1, installation 2 is a roller shutter installation. Figure 1 is an exploded perspective of installation 2, in which all the elements are oriented in the same position that they have when installation 2 is in a configuration mounted on a wall 4.

Installation 2 is fixed to wall 4 above an opening 6 made in this wall. The wall 4 and the opening 6 are not represented in figure 1, but are both visible in figures 3 to 7, the wall 4 also being visible in figure 2. The installation 2 is symmetrical with respect to a plane of symmetry P2 vertical and orthogonal to the wall 4.

In the example, wall 4 is vertical, while opening 6 is rectangular. For convenience, the "up" and "down" directions for the interpretation of the terms "up", "down", "upper" and "lower" are the directions taken with respect to the configuration of the installation. 2, mounted on the wall 6 vertical.

The terms “interior” and “exterior” are taken with reference to the volume delimited by the wall 4. In FIGS. 3 to 7, the interior is located on the left of the drawing while the exterior is located on the right of the drawing. .

The terms "internal sides" and "external sides", for the elements located on either side of the plane P2, designate the sides of these elements oriented respectively towards the plane of symmetry P2, and opposite the plane of symmetry P2.

The installation 2 comprises a top tube 8 and a bottom tube 10. The two top and bottom tubes 8 and 10 each have a cylindrical structure centered on a respective longitudinal axis A8 and A10 and are arranged horizontally in the configuration of FIG. 1. In the example, the top and bottom tubes 8 and 10 are pivoting, and the longitudinal axes A8 and A10 are winding axes because the tubes 8 and 10 are apron winding tubes.

In the example, the screens supported by the top and bottom tubes 8 and 10 are, depending on the case, a closing screen formed of rigid blades or an obscuring screen, such as a sun protection fabric or a fabric for protection against insects, these examples not being limiting. Each of the tubes 8 and 10 comprises three portions assembled longitudinally to each other, in which are housed respective members for controlling the rotation of the tubes 8 and 10 such as electric motors. Advantageously, the tubes 8 and 10 are made of metal.

In a variant not shown, the top and bottom tubes 8 and 10 can be controlled in rotation by manual means, such as winches.

Each of the tubes 8 and 10 has two ends opposite to each other, these ends each being pivotally mounted on a bearing 12. In the example, the bearings 12 are four in number in total and each have the shape of a a plate arranged in a vertical plane, with an internal side oriented towards the tube and an opposite external side having studs 14.

The installation 2 further comprises two flanges 16. The flanges 16 are arranged facing each other, symmetrically on either side of the plane P2, and each consist of a metal plate. Advantageously, the flanges 16 have an identical structure to each other.

For each of the flanges 16, an internal face 18 is defined as being the face of the flange 16 oriented towards the other flange 16, and an external face 20, opposite the internal face 18. Each flange 16 also has a lower edge 22, a lateral flange 24, orifices 26 and guide notches 28. The lower edge 22 and the guide notches 28 have directions parallel to each other and the lateral flange 24 is orthogonal to the notches 28. In the configuration of FIG. 1, the bottom edge 22 and guide notches 28 are horizontal and side flange 24 is vertical.

The orifices 26 pass right through each flange 16 and are orifices for receiving the pins 14 of the bearings 12. In the mounted configuration of the installation 2, the pins 14 are housed in the orifices 26 for receiving, the bearings 12 being fixed to the flanges 16. The top and bottom tubes 8 and 10 are thus mounted between, and pivoting on, the flanges 16 around the respective axes A8 and A10, and the axes A8 and A10 are orthogonal to the flanges 16.

The installation 2 further comprises two lower end pieces 30 and two upper end pieces 32. The lower and upper end pieces 30 and 32 are each two in number and are arranged symmetrically with respect to the plane of symmetry P2. Lower 30, respectively upper 32 end pieces, arranged facing each other with respect to the plane P2 thus have a structure symmetrical to each other.

Each of the lower end pieces 30 cooperates with the upper end piece 32 located on the same side of the plane P2. The sub-assembly formed by a flange 16, a lower end piece 30 and an upper end piece 32 located on the same side of the plane P2 defines a fixing support 34.

In other words, the installation 2 comprises two mounting brackets 34 having a structure symmetrical to each other and located opposite one another, symmetrically on either side of the plane of symmetry P2.

Each lower end piece 30 has a first wall 36, which is, in the configuration of FIG. 1, located in a vertical plane parallel to the wall 4, a second wall 38, which is located in a vertical plane orthogonal to the first wall, and a third wall 40, which is connected to the second wall and parallel to the first wall. The intersection edges of the walls 36, 38 and 40 parallel and define a deployment axis A30. In Figure 1, axis A30 is vertical.

The first wall 30 has a rectangular shape, arranged parallel to the axis A30 in its length. The first wall 30 also has two oblong holes 42, the largest dimension of which is parallel to the axis A30 and aligned along the axis A30. The oblong holes 42 are configured to cooperate with fasteners, such as screws, not shown.

The second wall 38 has a rectangular shape, is arranged parallel to the axis A30 along its length, and is linked to the first wall 36 by one side of the rectangle, while the opposite side is linked to the third wall 40 by one side. opposite of this rectangle. The third wall 40 has a rectangular shape, arranged parallel to the axis A30 in its length, and is oriented with respect to the second wall 38, opposite the first wall 36. In a plane orthogonal to the axis A30 , the walls 36, 38 and 40 have a baffle-shaped profile with right angles.

Each lower end piece 30 further comprises a first housing 44 and a second housing 46. The first housing 44 has a cylindrical shape of circular section centered on an axis orthogonal to the first wall 36 and orthogonal to the axis A30. The first housing 44 is configured to receive a stop 50, which here is a cylindrical flat head screw. The second housing 46 has a parallelepipedal shape, is arranged at the junction between the first wall 36 and the second wall 38, and defines a reception volume 48. The reception volume 48 is configured to house a housing 52, which is in the example an electronic control device for one of the motors of the top tube 8 or of the bottom tube 10. The installation 2 thus comprises two boxes 52, capable of controlling the rotational movements of the top 8 and bottom 10 tubes.

The lower end piece 30 also has a sliding surface 54, which is provided on portions of the first, second and third walls 36, 38 and 40. The sliding surface 54 thus has, in a plane orthogonal to the axis A30, a chicane-shaped profile with right angles.

The upper end piece 32 comprises an adjustment wall 56, which has a rectangular shape, is located in a plane parallel to the first wall 36 and comprises an oblong hole 58, the largest dimension of which is parallel to the axis A30.

The oblong hole 58 is configured to cooperate with a fixing member, not shown, such as a screw, so as to fix the upper end piece 32 on the wall 4.

The upper end piece 32 further comprises a body 60 which has the shape of a dihedral, with two by two orthogonal faces.

Each upper end piece 32 has a sliding wall 62. This sliding wall 62 has a profile complementary to that of the sliding surface 54 of the adjacent lower end piece 30, capable of guiding the upper end piece 32 in translation with respect to the lower nozzle 30 in a direction parallel to the deployment axis A30.

In Figures 5 and 6, the mounting bracket 34 is shown in a configuration where the overlap of the sliding surface 54 by the sliding wall 62 is maximum. The mounting bracket 34 is then in a so-called “closed” position.

A size H34 of a mounting bracket 34 is defined as being a measurement, parallel to the deployment axis A30, between two most distant points belonging to the lower end piece 30 and the upper end piece 32, as long as the surface 54 cooperates in a leaktight manner with wall 62. When the mounting bracket is in the closed position, the size H34 has a first value which is minimum. When the overlap of the surface 54 with the wall 62 is not maximum, the fixing support 34 is in a so-called "open" position, in which the size H34 has a second value, greater than the first value of the H34 footprint. It is understood that the size H34 can take any intermediate value, between the minimum value of the open position, and a maximum value.

Advantageously, the lower end piece 30 and the upper end piece 32 are in contact with each other, via the surface 54 and the wall 62 respectively, following a continuous contact contour. Advantageously, the contact between the sliding surface 54 and the sliding wall 62 is tight, that is to say that the air cannot pass between the surface 54 and the wall 62, when the surface 54 is in contact. contact with the wall 62.

Advantageously, sealing members, such as lip seals capable of ensuring the sealing of two surfaces sliding relative to each other, can be provided, at the interface between the sliding surface 54 and the sliding wall 62, to improve the seal between the upper end piece 32 and the lower end piece 30. These sealing members are not shown.

In the example, the lower and upper ends 30 and 32 are made of a synthetic polymer material. They are made, for example, by plastic injection. In a variant not shown, the sealing members can be integrated into the lower and upper ends 30 and 32 during manufacture, in particular by so-called “bi-material” injection.

Each of the upper end pieces 32 further comprises a first housing 45, which has a shape similar to the first housings 44 of the lower end pieces 30. Each first housing 45 has a cylindrical shape of circular section centered on an axis orthogonal to the wall of the fit 56 and orthogonal to axis A30. Each first housing 45 is configured to cooperate with a stop 51, which here is a cylindrical flat head screw similar to the stop 50.

In FIGS. 2 to 7, the fixing support 34 is shown assembled, the flange 16 bearing on the surface against the second wall 38 of the lower end piece 30. On the internal side, that is to say on the side facing the plane P2, the second wall 38 of each fixing support 34 has guide reliefs 64. The guide reliefs 64 project from each of the lower end pieces 30, and define guides parallel to each other and located in an orthogonal plane to the A30 deployment axis.

The guide reliefs 64 are designed to cooperate with the notches 28 of the flanges 16, that is to say to guide the flange 16 in translation relative to the lower end piece 30, in a direction parallel to the guide notches 28.

The relative position of the flange 16 with respect to the lower end piece 30 can thus be adjusted by a translation in direction parallel to the guide notches 28, the flange 16 then being immobilized with respect to the lower end piece 30 using screws 66, which are an example of fasteners. In a variant not shown, the screws 66 are replaced by pins or by clips.

Thus, the position of the top and bottom tubes 8 and 10 relative to the lower end piece 30 can be adjusted, to adapt, during assembly, the position of the tubes 8 and 10 to various sizes of apron and/or to various sizes of half lintel.

Each fixing support 34 further comprises a shim 68. Each of the shims 68 comprises a base 70, which is linked to two fixing walls 72. The base 70 defines a flat bearing surface, which is horizontal in the configuration of figures 1, 3, and 5 to 7.

The fixing walls 72 have the shape of parallelepipedic legs, elongated and arranged, in their length, orthogonal to the base 70. The fixing walls 72 are designed to be fixed to the flanges 16 by means of screws 74, which are an example of fasteners. In a variant not shown, the screws 74 are replaced by pins or by clips.

The spacing between the base 70 and the lower edge 22 of the flange 16, measured parallel to the axis of deployment A30, can be adjusted by the operator, depending in particular on the geometry of the half-lintel in which the support of fastener 34 is mounted. The shims 68 are thus adjustable shims and are sometimes called “soffit tabs”. More generally, it is understood that the wedge 68 makes it possible, during assembly, to adjust the position of the flange 16 relative to the half-lintel, in a direction parallel to the axis of deployment A30, to adapt to the various types of closing and/or solar protection screens, as well as the various half-lintel geometries, knowing that the deployment axis A30 is vertical when the system 2 is mounted in the half-lintel, as shown in FIGS. 1 at 3 and 5 at 7.

The installation of Figure 2 further comprises two slides 76 and two sockets 78. The two slides 76 each have the shape of sections which are arranged vertically along their length, on either side of the opening 6. The slides 76 are arranged symmetrically to one another on either side of the plane of symmetry P2 and define between them a guide plane P76. The guide plane P76 is parallel to the wall 4. The sockets 78, visible in FIGS. 1 and 3, are each fixed to an upper end of a respective slide 76, each of the sockets 78 having walls with a lower part aligned with the P76 guide plane and a flared upper part.

Installation 2 also includes a T1 apron and two 80 locks.

The apron T1 comprises slats 82, of rectangular shape horizontally along their length, the slats 82 being hinged together, that is to say movable in rotation relative to each other along a horizontal axis of rotation in the configuration of FIG. 1. The apron T1 defines, at a lower end, a lower slat 84, and at an opposite end, a upper slat 86.

The lock 80 comprises a front link 88, an intermediate link 90 and a rear link 92. The three links 88, 90 and 92 are hinged together along two horizontal axes in the configuration of Figure 1. More specifically, the rear link 92 is articulated with the intermediate link at one end, while at the other end the rear link 92 is connected to the upper blade 86 of the apron T1. The front link 88 is, for its part, linked in rotation to the intermediate link 90 and fixed to one of the top or bottom tubes 8 or 10. In the example of FIG. 1, the apron T1 is shown deployed in front of the opening 6 and is entirely located in a plane parallel to the guide plane P76. It is understood that the apron T1 is jointly guided by the slides 76 and by the tulips 78, the apron T being wound around the top or bottom tube 8 or 10 to which it is attached, when an operator controls the rotation of said top or bottom tube 8 or 10.

In FIG. 3, the silhouettes of the apron T1 and of another apron T2 are represented by hatched circles, which show the size of the aprons T1 and T2 when they are entirely wound around the lower and upper tubes 10 and 8 respectively , the portions of the aprons T1 and T2 passing through the sockets 78 or through the wings 76 not being shown.

In the example, the apron T2, which takes up much less space than the apron T1, is a protective canvas, such as sun protection or a mosquito net.

It is understood that depending on the nature of the aprons T1 and T2, the space required within the half-lintel varies and that, consequently, the positioning of the top and bottom tubes 8 and 10 within the half-lintel must be adjusted during assembly. As described above, the position of the flange 16 relative to the lower end piece 30 can be adjusted in various ways. It is of course possible to use a flange 16 of a geometry different from that of the examples, provided that the flange 16 cooperates with the lower and upper ends 30 and 32, as well as with the other elements of the fixing support 34 , such as the wedge 68 or the bearings 12. It is thus possible to use the fixing support 34 with various geometries of half-lintels and various configurations, in particular when the aprons T1 and T2 are of various natures, by simply changing the flange 16 and without changing the other elements of the mounting bracket 34. In this sense, the mounting bracket 34 is modular.

Installation 2 further comprises an upper profile 94 and a lower profile 96. The upper 94 and lower profile 96 each have an L-shaped section with a double branch and are arranged horizontally along their length. The single branch of the L of the upper profile 94 has a bearing face 98, while the double branch of the L defines a reception volume V100 with a U-section, which is located in a vertical plane and is open downwards in the configuration of Figure 1. The upper section 94 has two ends which cooperate with a respective upper end piece 32. In other words, the upper section 94 connects the two upper ends 32 of the installation 2 to each other.

Similarly, the lower profile 96 has two ends, which cooperate with a respective lower end piece 30. In other words, the lower profile 96 connects the two lower end pieces 30 of the installation 2 to each other. The single branch of the L of the lower profile 96 has a support face 106, while the double branch of the L defines a reception volume V108 with a U-section, the volume V108 being located in a vertical plane and is open at the top in the configuration of figure 1.

The V100 and V108 reception volumes are arranged facing each other, symmetrically on either side of a plane orthogonal to the A30 deployment axis.

In the example, the upper and lower sections 94 and 96 are each formed of two angles at right angles cooperating with each other. In a variant not shown, one and/or the other of the upper and lower sections 94 and 96 can be formed in one piece.

Installation 2 further comprises a panel 110. The panel 110 is a rectangular plate, made of an insulating and waterproof material. In Figure 1, the panel 110 is shown transparent by dashed lines to facilitate reading. In FIGS. 3 to 7, the panel 110 is housed jointly in the reception volumes V100 and V108. In other words, the reception volumes V100 and V108 together define a reception volume of the panel 110.

Advantageously, the panel 110 is mobile within the reception volumes V100 and V108, that is to say that the lower 96 and upper 94 profiles can each slide relative to the panel 110, in translation in a direction parallel to the A30 deployment axis.

Advantageously, the panel 110 is able to slide in a sealed manner within the reception volumes V100 and V108, whatever the relative position of the panel 110 within the reception volumes V100 and V108. By "tight" is meant here that the air infiltration between the panel 110 and the walls of the reception volumes V100 and V108 are minimal, even zero.

Advantageously, when the panel 110 is housed in the reception volumes V100 and V108, the panel 110 is also in leaktight support on the third walls 40 of each of the lower end pieces 30. Together, the panel 110 is in leaktight support on the bodies 60 of the top end caps 32.

The sub-assembly comprising the two lower end pieces 30, the two upper end pieces 32, the upper and lower sections 94 and 96 defines a trapezium-shaped frame, which is sealed off by the panel 110.

In Figures 2 and 3, the installation 2 is shown in assembled configuration and mounted within a half-lintel 102, which is described below. The half-lintel 102 and shown in Figures 2 to 7.

The opening 6, formed in the wall 4, is partially closed off in its upper part by a partition 112. The partition 112 is a brick or concrete masonry element, which here comprises cells, has a parallelepiped shape arranged horizontally in its length and flush with wall 4 on the exterior side of the building. In the example, the partition 112 and the wall 4 are covered, on the outside, with a finishing layer 114. The finishing layer 114 comprises for example one or more layers of a mineral or organic coating.

The opening 6 is limited upwards by a beam 116. The beam 116 has a lower face 118, which is located in a horizontal plane and is oriented towards the opening 6. Alternatively, the lower face 118 can be part of another masonry unit such as a slab. The partition 112 is supported on the lower face 118 of the beam 116 by a high end, while the partition 112 is linked, at its lower end, to an insulating plate 120. The insulating plate 120 here has a honeycomb structure and is located in a horizontal plane and orthogonal to the partition 112. The lower face 118 of the beam 116, the partition 112 and the insulating plate 120 together delimit an assembly volume V122, in which are housed several elements of the installation 2, among which the two fixing supports 34, the upper 94 and lower 96 profiles, the upper and lower tubes 8 and 10 connected to the fixing support 34 via the bearings 12, as well as, when rolled up, the aprons T1 and T2, optionally fixed to the bottom or top tubes 10 or 8, using locks 80. The list of these elements is not exhaustive.

Set back from the partition 112 towards the inside of the building, the installation 2 comprises a joinery 124, which is for example the joinery 124 of a window. The carpentry 124 generally has a rectangular shape and is located in a vertical plane set back from the partition 112 relative to the outside of the wall 4. A carpentry of the carpentry 124 type generally comprises a fixed part, called "frame", which is fixed to the wall, and a movable part, called "leaf", movable in rotation relative to the frame. In the example of Figures 3 to 7, the joinery 124 is partially shown, only an upper upright 126 of the frame of the joinery 124 being shown in section.

A first portion of the opening 6 is thus partially closed off by the carpentry 124, while a complementary portion of the first portion of the opening 6, delimited by the upper upright 126 of the carpentry, by the side walls 138 of the wall 4 and by the beam 116, defines an access door 140 of the half-lintel 102.

The joinery 124 partially closes the opening 6. Advantageously, the lower section 96 cooperates with the upper upright 126 of the joinery 124 in a sealed manner. As a variant not shown, other complementary sealing means can be used, such as a self-adhesive membrane, a strip of compressed foam or mastic.

Similarly, the upper profile 94 cooperates with the lower face 118 of the beam 116 in a sealed manner, this sealing being able to be supplemented by other complementary sealing means as mentioned above.

In the configuration of FIG. 3, the opening 6 is sealed off by the carpentry 124 on the one hand and, between the upper upright 126 and the beam 116, by a continuous contour formed by the lower section 96 resting on the upper upright 126, the panel 110 cooperating in its lower part with the reception volume V108 of the lower profile 96 and, in its upper part, with the reception volume V100 of the upper profile 94, the support face 98 of the profile upper 94 cooperating with the lower face 118 of the beam 116.

The stops 50, cooperating with the cylindrical housings 44 provided on the lower and upper ends 30 and 32, cooperate together with a trim panel 128. The trim panel 128 is made for example of a plasterboard, has a shape rectangular and makes it possible to hide installation 2 on the interior side of the building. Advantageously, the trim panel 128 cooperates reversibly with the stops 50, that is to say the trim panel 128 is removable. In the example, the stops 50 are screws which have a cylindrical head made of ferromagnetic material, while the covering panel 128 comprises magnets, not shown, which hold the covering panel 128 in position with respect to the stops 50 reversibly.

In the example of the figures, the installation 2 comprises two mounting brackets 34, connected by the upper 94 and lower 96 sections, while two top and bottom tubes 8 and 10 are pivotally mounted on the flanges 16, these elements defining together a roller shutter mounting sub-assembly 130. In a variant not shown, only the bottom tube 10 is mounted on the flanges 16, in which case the assembly sub-assembly 130 comprises only a single tube supporting a closing or solar protection screen.

Among the elements that make up the mounting sub-assembly 130, the two lower end pieces 30 connected to each other by the lower profile 96 define a lower part 132 of the mounting sub-assembly 130. Similarly, the two upper end pieces 32, connected between them by the upper section 94 together define an upper part 134 of the mounting sub-assembly 130.

The upper part 134 of the mounting sub-assembly 130 is guided in translation relative to the lower part 132 of the mounting sub-assembly 130, parallel to the deployment axis A30, thanks to the upper 32 and lower 30 end pieces located at the ends lower 96 and upper 94 profiles.

We now describe a roller shutter mounting method using the mounting sub-assembly 130 as described above.

FIG. 4 illustrates a first step in the method of mounting the roller shutter, consisting in inserting the mounting sub-assembly 130 into the mounting volume V122. The assembly sub-assembly 130 then has a minimal bulk, that is to say that the upper ends 32 of the two fixing brackets 34 are in the closed configuration, in which the bulk H34 is minimal.

The upper upright 126 of the carpentry 124 includes a rim 136. The rim 136 projects from the upper upright 126 and extends vertically in the direction of the beam 116 located opposite.

The mounting sub-assembly 130 is presented with the flanges 16 oriented towards the partition 112, that is to say towards the front of the mounting volume V122, while the upper and lower sections 94 and 96 are oriented to the opposite the partition 112. The mounting sub-assembly 130 is inserted into the mounting volume V122 following a movement which includes a component of horizontal translation directed towards the partition 112, this component being represented by the arrow F1 in FIG. , and a component of rotation about a horizontal axis substantially coinciding with the rim 136, represented by the arrow F2 in FIG. 4. In the example of the figures, the wedges 68 fixed to the flanges 16 are the furthest point, parallel to the deployment axis A30, of the upper section 94. The rotational movement, represented by the arrow F2, allows the flange 136 to pass during the insertion movement. Of course, the insertion movement can be changed depending on the geometry of the mounting subassembly 130 and the geometry of the rim 136.

In FIG. 5, the mounting subassembly 130 is in an intermediate position of the insertion movement, in which the deployment axis A30 is vertical, the upper channel 94 being in contact with the beam 116. The movement of insertion into the mounting volume V122 continues with a horizontal translation directed towards the partition 112, as represented by the arrow F3 in FIG. 5. The movement of the mounting sub-assembly 130 along the arrow F3 continues until that the lower end pieces 30 come into contact with the inner sides of the side walls 138 of the wall 4, in a configuration similar to that of FIG. 2. The insertion of the mounting sub-assembly 130 into the mounting volume V122 is then completed.

In a following step, illustrated by FIG. 6, the assembly subassembly 130 is wedged against the carpentry 124, following a vertical translational movement directed downwards represented by the arrow F4 in FIG. 6. This translational movement is continues until the lower part 132 comes into contact with the upper upright 126 of the carpentry 124. More specifically, the bearing surface 106 of the lower profile 96 is then in contact with an upper face of the upper upright 126 of the carpentry 124. Together, the wedges 68 rest on the insulating plate 120.

It is understood that, depending on the geometry of the assembly volume V122, in particular depending on the position of the insulating plate 120, the relative position of the wedges 68 with respect to the respective flanges 16 is adjusted by an operator prior to step d insertion of assembly subassembly 130 into assembly volume V122.

Similarly, in another step prior to the step of inserting the mounting subassembly 130 into the mounting volume V122, the relative position of the flanges 16 with respect to the lower end pieces 30 can be adjusted according to the geometry the assembly volume V122, the geometry of the flanges 16, as well as the nature of the aprons T1 and T2 intended to be wound on the top and bottom tubes 8 and 10, by a translation parallel to the axis of the guide notches 28 , followed by immobilization of the flanges 16 to the respective lower end piece 30 using the screws 66.

Once the lower part 132 is wedged on the carpentry 124, the lower part 132 is fixed to the wall 4. More specifically, the two lower end pieces 30 are fixed to the side walls 138 of the wall 4 by fixing means, such as screws not shown, cooperating with the oblong holes 42.

In a next step, illustrated by FIG. 7, the upper part 134 of the assembly sub-assembly 130 is deployed, following a translation movement parallel to the axis of deployment A30 illustrated by the arrow F5 in FIG. 7, until until the upper part 134 comes into contact with the beam 116. During this deployment, the upper ends 32 are guided in translation parallel to the axis A30 by the cooperation of the sliding surfaces 54 and the sliding walls 62.

More precisely, the support face 98 of the upper profile 94 is moved until it comes into contact with the lower face 118 of the beam 116.

In a next step, the upper part 134 is fixed to the wall 4. More specifically, the upper end pieces 32 are fixed in the side walls 138 of the wall 4, by means of fixing members, such as screws not shown, cooperating with the oblong holes 58.

At the end of this assembly step, the top and bottom tubes 8 and 10 are positioned within the assembly volume V122 thanks to the flanges 16 fixed to the lower and upper end pieces 30 and 32, which are themselves fixed to the wall 4 .

It follows from the foregoing that the assembly subassembly 130 can be mounted in half-lintels having geometries different from those of the half-lintel 102 shown in the figures and that it makes it possible, in particular, to compensate for geometric defects masonry.

Advantageously, the two mounting brackets 34 of the mounting sub-assembly 130 can be deployed at different degrees from each other, that is to say that the size H34 of one of the two mounting brackets fixing 34 may be different from the overall dimensions H34 of the other of the two fixing supports 34 at the end of assembly. Thus, if the beam 116 has defects of horizontality, the upper ends 32 of the two mounting brackets 34 of the assembly sub-assembly 130 can be deployed to different degrees from each other, that is to say to say that the upper profile 94, resting on the lower face 118 of the beam 116, is not horizontal in order to compensate for the defects of horizontality of the beam 116.

Once the mounting sub-assembly 130 has been positioned and immobilized in the mounting volume V122 as described above, the trim panel 128 is put in place between the upper upright 126 and the beam 116, the trim panel 128 being resting on the stops 50.

The installation 2 shown in the figures is a roller shutter installation, comprising tubes 8 and 10 pivotally mounted with respect to the flanges 16, the aprons T1 and T2 being respectively a blackout apron and a protective canvas.

In a variant not shown, the winding tube 10 is replaced by a tube fixed to the flanges 16 and which extends along a longitudinal axis comparable to the longitudinal axis A10, while the apron T1 is replaced by an apron with adjustable blades , also called adjustable sunshade or BSO. The BSO is linked to the tube by cords. One or more electric motors drive one or more reels of these cords, so as to control the vertical or orientation movements of the BSO.

The embodiments and variants mentioned above can be combined with each other to generate new embodiments of the invention.
