Description

Reflector device adapted to be fixed in a horizontal position at a building opening

The present invention relates to the field of reflectors intended to be installed in the environment of an opening, such as a window or door window, to improve the natural lighting of the interior of a dwelling.

The wish to optimize the natural lighting of the interior of a building, a house or an apartment, by returning to this interior the natural light coming from the sun has been known for a very long time.

The inventor has himself proposed different types of vertical reflectors described in documents FR-A-2936584 and FR-A-2963663.

It is now an object of the present invention to provide a new reflector concept for recovering solar natural lighting and to break with previously proposed solutions.

Another objective of the invention is to propose means of limited cost to optimize the development of the concept.

Another breakthrough element of the invention is to break with the vertical arrangement so far proposed for solar light reflectors. In this context, an objective of the invention is to propose solutions that make it possible to overcome the constraints associated with the very great diversity of geometry and dimensions of existing openings in buildings.

Finally, an additional element of rupture with respect to the state of the art is a step no longer aimed as in the state of the art to recover the direct radiation from the sun to return it to the interior of a building , which in practice limits the use of such systems on the upper floors in urban buildings, but to recover the clarity of the day, that is to say the indirect radiation. The invention thus allows a generalization to any type of building, including the low floors of urban buildings, see again what can be called skylights in a Haussmann style architecture or equivalent.

In the description which follows and in the appended figures, the identical means taken up in the various embodiments will be accompanied by identical references.

The different embodiments of reflector devices illustrated in the appended figures comprise, as indicated previously: a plate 100 forming a reflector,

a support box 200 that can be standard for all the embodiments,

means 300 serving to support the caisson 200 on an element related to the shell of a building, and

- Means 400 integrated into the box 200 and adapted to allow an angular adjustment of the inclination of the box 200 about a horizontal axis 0-0 which coincides with a major axis of the plate 100 forming a reflector, relative to the support means 300, to allow to optimize the capture and the return to the interior of the building of the light of the day.

As will be indicated later, according to some embodiments of the invention, the means 300 for supporting the box 200 and the tilt adjustment means 400 may be formed on a common element.

The plate 100 forming a reflector can be the subject of many embodiments.

It is preferably a multilayer aluminum plate. The reflector plate 100 is preferably designed thin to be lightweight and thus allow implantation on many elements of large building works. The corollary of the lightness of the support plate 100 is its low mechanical strength. In the context of the invention, as will be described below, the mechanical strength of the assembly, in particular the resistance to the risk of deflection, is provided by the structure of the associated box 200.

The reflector plate 100 is thus preferably formed of a rectangular contour plate comprising two longitudinal edges 102, 104 parallel to each other and two transverse edges 106, 108 parallel to each other and orthogonal to the lateral edges 102, 104. The angles 101, 103, 105, 107 of the plate 100 are preferably rounded.

By way of non-limiting example, support plates 100 may be provided whose length L1 (distance between the transverse edges 106 and 108) is adapted to the width of the openings, for example 60 cm, 80 cm, 100 cm, 120 cm or more and one width L2 (distance between the longitudinal edges 102 and 104) of the order of 25cm.

The support box 200 can also be the subject of many embodiments.

It is preferably made of metal, for example aluminum.

Preferably the box 200 has a constant cross section over its entire length. It can be formed by extrusion of a profile. However according to the invention the box 200 is preferably made by folding an initially plane sheet around different edges 201, 203, 205, 207 parallel in them.

The casing 200 typically has a general cross-sectional shape in open U-shape, extended on its blanks by two coplanar lateral planar flanges 220, 230.

The U-shaped body 210 of the box 200 comprises a plane bottom 212 parallel to the flanges 220, 230 and two wings or walls 214, 216 transverse to the bottom 212 and flanges 220, 230 and ensuring the connection respectively between one of the edges 212 bottom and one of the flanges 220, 230.

According to the preferred embodiment shown in the accompanying figures, the wing or wall 214 which is connected to the bottom 212 by the fold line 205 and the flange 230 by the fold line 207 extends perpendicularly to the bottom 212 and to this end. flange 230.

By against the wall or wing 216 is inclined of the order of 135 degrees to the bottom 210.

The wall 216 extends outwardly away from the bottom 212. The wall 216 is connected to the bottom 212 by the fold line 203 and the flange 220 by the fold line 201.

Those skilled in the art will understand that the two wings 214, 216 which extend transversely to the support plane defined by the flanges 220, 230 serve as a stiffener to the box 200 and to the entire device according to the present invention and allow to support the reflector plate 100 in the flat state, without arrow, along its entire length.

The length L3 of the box 200 considered parallel to the fold lines 201, 203, 205 and 207 is less than the length L1 of the reflector plate 100. The length L3 of the box 200 is typically between one third and two thirds, or even four fifth, of the length L1 of the reflector plate 100.

The width L4 of the box 200 taken between the two extreme free edges of the flanges 220, 230 is less than the width L2 of the support plate 100. The plate 100 forming a reflector is advantageously fixed on the box 200 by gluing on the flanges 220, 230.

We will now describe the means 300 forming a support of the box 200 on an element related to the shell of the building, as shown in Figure 1.

According to this first embodiment shown in Figure 1, the support means 300 are formed of at least two separate structures of calipers 310 to be clamped on a horizontal bar B of a building railing.

Each stirrup 310 essentially comprises two blades

320, 330 intended to be respectively placed on either side of the bar B in diametrically opposite position and tightened on the bar B by means of threaded means 340, 345 ensuring when tightening the approximation of the blades 320, 330.

The blades 320, 330 may be curved of complementary geometry to the outer surface of the bar B. According to the embodiment shown in Figure 1 the blades 320, 330 are straight blades to adapt to any railing geometry .

The blade 320 has according to the variant illustrated in Figure 1 an L-shaped geometry formed of two wings 322, 324 orthogonal. The shortest wing 324, vertical in use, has both an aesthetic dressing function to partially conceal the clamping means 340, 345 and also a safety function and positioning aid, providing a lateral abutment means 300 relative to the bar railing B during the establishment of the device.

Clamping means 340, 345 may be the subject of numerous variants. They are preferably formed of bolts, studs or threaded rods engaged with one of the blades 320, 330, passing through the other blade 330, 320 and cooperating moreover with complementary bolts (referenced 341 and 346 on the variant of FIG. FIG. 2) making it possible, in a manner known per se, to clamp the two strips 320, 330 on the bar B. The flange 322 of the blade 320, horizontal in use, preferably has a length greater than the second blade 330 and has at its end a through hole 321 for receiving the fixing means 400 angular adjustment.

According to the embodiment shown in FIG. 1, the angular adjustment means 400 are formed essentially of a tube 410, for example an aluminum tube with a diameter of 20 mm, extending along the length L1 of the plate 100 and the length L3 of the box 200, that is to say parallel to the longitudinal edges 102, 104 and fold lines 201, 203, 205 and 207.

The tube 410 preferably has its two ends 402, 404 flattened and provided with through orifices 403, 405. The orifices 403, 405 are intended to be placed opposite the orifices 321 of the two stirrups 310 in order to fix the tube 410 on the stirrups 310 by means of threaded means or any equivalent means illustrated under reference 420 in FIG.

The tube 410 is intended to be placed inside the box 200, in a position contiguous to the wall 214. To allow the connection between the tube 410 and the stirrups 310, the box 200 is provided with two cutouts 250 extending in part in the base of the wall 214 and in the bottom 212 transversely to the fold line 205. The ends of the blades 322 provided with the orifice 321 are engaged inside the cutouts 250.

Of course the distance separating the two cutouts 250 must be adapted to the length of the tube 410 retained according to the specific implantation conditions and the stirrups 310 must be clamped on the bar B of the guardrail at a distance corresponding to the distance between these two cutouts 250.

The angular adjustment of the reflector plate 100 and the box 200 around the horizontal axis 0-0 is ensured by operating a relative immobilization in selected position of the tube 410 on the box 200. To do this the tube 410 is pinched between the wall 214 and two plates 430, 440 biased toward the wall 214 by threaded means or equivalent 432, 442. To install the device illustrated in Figure 1 on a bar B balustrade is preferably carried out as follows (the device being delivered preassembled, that is to say the tube 410 placed in the box 200 between the wall 214 and the pads 430 and 440 and fixed by its ends on the blades 320 stirrups engaged in the blanks 250 of the box 200, the reflector plate 100 of selected dimensions being fixed by gluing on the flanges 220 and 230 of the box):

. firstly, the two stirrups 310 are tightened on the bar B,

. then the box 200 is oriented angularly around the axis 0-0 and immobilized in position by clamping the means 432 and 442.

FIG. 2 shows an alternative embodiment of the stirrups 310 according to which the blade 320 is equipped with two transverse U-shaped profiles 326, 328, vertical in use, housing the threaded rods 340, 345 in order to improve the aesthetic system and slidably receiving the ends of the blade 330 as shown in Figure 2.

FIG. 2 also shows two strips 350, 352 of protective material, for example of elastomer, such as EPDM or equivalent, intended to be placed on the facing surfaces of the blades 320, 330 on either side of the bar B guardrail to protect it during tightening.

The installation of the device illustrated in FIG. 2 is identical to that shown in FIG.

The variant embodiment shown in FIG. 3 will now be described.

This figure 3 shows a plate 100 forming a reflector and a box 200 as described above with reference to FIG.

According to this second embodiment, the tube 410 serving as an angular adjustment means to the device around the axis 0-0 is also involved in the production of the means 300 supports of the box 200 on the element related to the structural work of the building. This is the frame or embrasure of an opening.

More precisely according to the embodiment shown in FIG. 3, the support means 300 of the casing 200 on the element connected to the shell of the building, in this case the recess of an opening, are elements of the telescopic type capable of extension along the OO axis.

Numerous embodiments of telescopic means can be envisaged within the scope of the invention.

According to the representation given in FIG. 3, the telescopic means are formed of two elements capable of extension or controlled shrinkage along the axis 0-0: the tube 410 and a threaded rod 360 engaged in the tube 410 and of which the penetrating extension in the tube 410 is controlled by an assembly formed of a nut 362 and a washer 364, engaged on the rod 360 and resting on the end of the tube 410. The tightening of the nut 362 on the stem 360 increases the extension of the rod 360 located inside the tube 410 and thus reduces the extension of the assembly 300 between its two ends. Conversely, the loosening of the nut 362 urges the threaded rod 360 towards the outside of the tube 410 and thus tends to extend the length of the element 300 along the axis 0-0 and thereby to ensure the clamping of the means 300 / 400 between two opposite faces of the embrasure of an opening.

As can be seen in FIG. 3, preferably the tube 410 and the threaded rod 360 constituting the telescopic means are provided at their ends with respective bearing flanges 370.

These flanges 370 extend in mean planes perpendicular to the axis 0-0 of the tube 410 and are intended to rest against the opposite faces of the embrace of the opening. The flanges 370 may be the subject of many embodiments.

Preferably they have an indented shape at an edge intended to rest against the frame of the openings or the shell. In this case the flanges 370 have a general shape of A defining at its base two feet 372, 374 intended to rest against the frame of the opening or the shell. The presence of two separate feet 372, 374 and not a solid edge or large face resting against the frame allows both to facilitate the movement of the telescopic support system opposite the opening frame and to facilitate the positioning of that regardless of the geometry of the frame.

The flanges 370 are supported on the lateral uprights of the frame of the window at the feet 372 and 374. This allows a guide in translation of the device. This movement makes it possible to adjust the height of the panel forming reflector 100. This makes it possible to place it at the foot of the glazing light of the opening whatever the configuration of the threshold and the window sill. This has the advantage of optimizing the operation of the reflector systematically.

If necessary, the outer face of the flanges 370 may be covered with an elastomer element intended to prevent any degradation of the faces of the embrasure during the extension of the means 300.

To install the device illustrated in FIG. 3 in an opening embrasure, the procedure is preferably as follows (the device being delivered pre-assembled, that is to say the tube 410 placed in the box 200 between the wall 214 and the platelets 430 and 440 and the reflector plate 100 of selected dimensions being fixed by gluing on the flanges 220 and 230 of the box):

. initially, the telescopic tube 410/360 is lengthened by force, the two flanges 370 resting on opposite sides of the recess and the feet 372 and 374 of these flanges resting against the chosen bearing zones of the opening frame ,

The embodiment described above with reference to Figure 3 requires no drilling in the shell to ensure the attachment of the device. However, it will be noted the presence in FIG. 3 of a piercing 376 passing through each flange 370 according to its thickness. This piercing or orifice 376 allows optional, if the user wishes, a secured fastening screw on the shell, for example for an application on the ground floor of a building to avoid the risk of theft.

FIG. 4 shows an alternative embodiment in which the means 300 forming a support of the box 200 on an element connected to the shell of a building and the means 400 integrated into the box to allow an angular adjustment of the inclination of the box around a horizontal axis 0-0 are formed of a lug 450 fixed to the outer face of the wall 214 of the box by any appropriate means, for example by threaded means or equivalent 452, and capable of angular orientation around an axis AA orthogonal to the longitudinal axis OO. The length L5 of the tab 450 situated between the articulation axis A-A and its free end is greater than the height of the wall 214 situated between the articulation axis A-A and the external surface of the bottom 212.

Those skilled in the art will understand that in the retracted position of the tab 450 against the flange 230, the box rests on the shell by the bottom 212. However, when the tab 250 is pivoted in the direction of a perpendicular position at the bottom 212, the box 200 rests on the shellwork by the free end of the tab 430. Thus the variable and progressive angular inclination of the tab 430 about the axis AA makes it possible to ensure an adjustment of the inclination angular of the box 200 by pivoting about a horizontal axis which corresponds to the folding edge 203 (or defined by support pads 460) resting on the shell. If necessary the box can rest against the shell by the outer surface of the wall 216.

The tab 250 thus forms an adjustable orientation support leg which makes it possible to adjust the inclination of the box around the axis O-O.

In practice it can be provided several tabs 430 distributed over the length of the box 200 to improve the stability of the assembly.

FIG. 4 shows skates 460, for example made of elastomer, such as EPDM, capable of being fixed on the outer surface of the wall 216 to improve the stability of the assembly and to avoid to deteriorate the shell, or can be used as axis of articulation when adjusting inclination.

To install the device illustrated in Figure 4 is preferably carried out as follows (the device being delivered preassembled, that is to say the reflector plate 100 of selected dimensions being fixed by gluing on the flanges 220 and 230 of the box and the leg 450 pre-positioned on the wall 214):

. the casing 200 is supported on its support of the shell, typically on an internal window support,

. then the box 200 is oriented angularly around the axis 0-0 corresponding to the fold line 203 by pivoting the tab 450 and immobilized in position by clamping the means 452.

A variant of Figure 4 is sketched in Figure 8. This variant comprises a tab 450 attached to a tube 410 adjustable angularly about the axis 0-0 in the previously described manner. The tab 450 emerges outside the box 200 and serves as a support to adjust its inclination.

FIG. 5 shows a variant embodiment according to which the tube 410 is adapted to be fixed at the level of the cutouts 250 on L-shaped tabs 380. More specifically, the tube 410 is fixed on a first flange 382 of the tabs 380. second wing 384 of the L-shaped lugs 380 is provided with means 385, perforation or light for example, allowing appropriate attachment to a structural element as seen in FIG.

To install the device illustrated in Figure 5 is preferably carried out as follows (the device being delivered preassembled, that is to say the tube 410 placed in the box 200 between the wall 214 and the plates 430 and 440 and fixed by its ends on the wings 382 of the tabs 380 engaged in the blanks 250 of the box 200, the reflector plate 100 of selected dimensions being fixed by gluing on the flanges 220 and 230 of the box):

. firstly, the two legs 384 are fixed by any appropriate means on a structural element, . then the box 200 is oriented angularly around the axis 0-0 and immobilized in position by clamping the means 432 and 442.

FIGS. 6 and 7 show another variant of embodiment according to which the box 200 is adapted to be fixed on a bar B of railing by two clamps 390 of clamping.

The box 200 may be identical to that described above. However, as illustrated in FIGS. 6 and 7, the bottom 212 of the box 200 is preferably provided with a dihedral form 213, longitudinal and concave outwards, intended to overlap the bar B in order to improve the stability and the positioning of the box 200 on the bar B. The dihedron 213 is formed of two planes made by folding. Alternatively it may be a cylindrical cap of revolution.

The angular adjustment of the casing 200 about a horizontal axis 0- 0 coinciding substantially with the axis of the bar B is defined by one or more elastic member (s) 392 forming a loop whose two ends 394, 396 are fixed on the casing 200 on either side of the bar B. The element 392 thus has two strands 395, 397 whose common portion 398 opposite the ends 394, 396 surrounds a secondary element BS guard rail underlying the principal bar B.

By adjusting the relative length of the two strands 395, 397 by displacement of the connecting element 398 around the tube BS, the inclination of the box 200 is adjusted and the reflector.

To install the device illustrated in FIGS. 6 and 7 on a balustrade bar B, the procedure is preferably as follows (the device being delivered pre-assembled, that is to say the reflector plate 100 of selected dimensions being fixed by gluing on the flanges 220 and 230 of the box 200, the clamps 390 being prepositioned on the box 200 and the adjusting element 392 being fixed by a first of its two ends on the box 200):

. firstly, the box 200 is placed on the bar B,

. then the box 200 is oriented angularly about the axis 0-0 and immobilized in position by adjusting the length of the two strands 395 and 397 and fixing the second end of the element 392 on the box 200.

FIG. 8 shows the implantation of several reflector devices according to the present invention, respectively corresponding to the embodiments illustrated in FIGS. 1 or 2 on a guardrail bar B, FIG. 3 outside in an embrasure. opening, Figure 4 on a support or inner shelf window and Figure 5 on a vertical field of the internal support. FIG. 8 also shows the possibility of juxtaposing several reflector devices of the various types mentioned above if it is desired to optimize the recovery of daylight.

Of course, the present invention is not limited to the embodiments that have just been described, but extends to any variant within its spirit.

For example, it is possible to pre-machine various blanks 250 and / or different pre-drills in the different elements to allow easy adaptation to the actual dimensions of the installation site.

The outer surface of the reflector plate 100 may also be subject to any suitable treatment, for example a diffusing coating.

The present invention provides a consumer solution, so easily accessible and easy to implement by the user.

Almost all the embodiments proposed in the context of the invention can be installed without special tools or at least with simple tools without drilling. Thus the installation of the device is not destructive of the shell.

The devices according to the invention are easily adjustable and removable.

They are functional all the time, at all times and at all times of the day. And they adapt to any type of window and / or railing or railing.

The horizontal arrangement still supported on a component related to the shell provides total security. The combination of the box 200 and the plate 100 makes it possible to have a coherent and robust element that is perfectly flat, despite the fact that the reflector plate 100 is made economically.

The system according to the present invention is modular in that different elements, for example the plate 100, the box 200 and the tube 410 are common to several embodiments.

Those skilled in the art will appreciate that the solutions proposed in the context of the present invention, in particular that represented in FIG. 3 which comprises telescopic support means, make it possible to overcome the fact that the threshold of a window can hide the reflector and obscure its effect when it is attached to the window sill. As mentioned in the preamble this situation, particularly problematic because of the multiplicity of cases and the variability of the dimensions of the frame, the threshold and the window sill, is perfectly solved by the means according to the invention.

Embodiments according to the present invention shown in the accompanying FIGS. 9 to 13 will now be described to illustrate the possibility, in the context of the present invention, of forming the support box 200 by the combination of a support plate 260 and spacers, such as glue strips.

FIG. 9 represents a plan view of a support plate 260 according to an alternative embodiment of the present invention forming a box 200 in combination with sizing strips ensuring the fixing of the support plate 260 on the rear face of FIG. a plate 100 forming a reflector, or in combination with any equivalent spacer. The inventors have indeed determined that sizing strips with a minimum thickness of one millimeter are sufficient to constitute a box configuration capable of providing the required rigidity. Typically the aforementioned sizing strips can be positioned longitudinally in the vicinity of the two lateral edges 262, 264 of the support plate 260, between the support plate 260 and the plate 100 forming a reflector, for example under the zones referenced C in FIG. 9.

By analogy with the embodiments previously described with reference to FIGS. 1 to 8, the support plate 260 corresponds to the bottom 212 and the sizing strips C correspond to the wings or walls 214, 216 transverse to the bottom 212 thanks to their thickness. . The faces of the gluing strips C in contact with the reflector plate 100 correspond to the coplanar flanges 220 and 230.

According to the embodiment shown in Figure 9 the support plate 260 is formed of a rectangular contour plate comprising two longitudinal edges 262, 264 parallel to each other and two transverse edges 266, 268 parallel to each other and orthogonal to the side edges 262, 264. The angles 261, 263, 265, 267 of the plate 260 are rounded.

The plate 260 is preferably made of metal, for example aluminum.

The length of the plate 260 considered parallel to the longitudinal edges 262, 264 is less than the length L1 of the reflector plate 100. The width of the plate 260 taken between the two longitudinal edges 262, 264 is smaller than the width L2 of the support plate 100.

As can be seen in FIGS. 9, 10 and 13, the plate 260 also has a plurality of tabs 270, 272, 274, 276 and 280, 282, 284 and 286, precutable foldable on demand depending on the support configuration. sought.

The tabs 270, 272, 274, 276 and 280, 282, 284 and 286 may for example be pre-cut by laser cutting.

The plate 260 thus has a first pair of tabs 270, 272 disposed respectively on the two longitudinal ends of the plate 260, close to a first longitudinal edge 262. The tabs 270, 272 are individualized in lights 271, 273. They are connected to the mass of the plate 260 by lines of weakness which define transverse hinge lines, perpendicular to the edges 262 and 264. In the original rest position, the tabs 270, 272 extend in the thickness of the plate 260 as illustrated in FIG. 272 can, however, be bent at the 90 ° request of the mid-plane of the plate 260 as seen in FIG. 10 to serve as a support for any suitable support means 300, for example means 300 for securing to a Balcony railing as shown in Figure 10.

According to the embodiment shown in Figures 9, 10 and 13 the plate 260 further comprises a second pair of tabs 274, 276 also disposed respectively on the two longitudinal ends of the plate 260, but near the second longitudinal edge 264. The tabs 274, 276 are individualized in lights 275, 277. They are connected to the mass of the plate 260 by lines of weakness which define transverse lines of articulation, perpendicular to the edges 262 and 264. In the rest position of Origin, the tabs 274, 276 extend in the thickness of the plate 260 as shown in Figure 9. The tabs 274 and 276 can, however, be folded at the 90 ° request of the middle plane of the plate 260 as one see it in Figure 10 to serve as a support for any appropriate support means 300, for example means 300 for securing the mounting on a cross 480 for wall mounting.

According to the embodiment shown in Figures 9, 10 and 13 the plate 260 also comprises two other pairs of legs 280 and 282, respectively 284 and 286, disposed between the legs 274 and 276 near the edge 264. The legs 280 , 282, 284 and 286 are individualized in lights 281, 283. They are connected to the mass of plate 260 by lines of weakness which define longitudinal lines of articulation, parallel to edges 262 and 264. The lines articulation of the legs 280 and 284 are aligned with each other and respectively the hinge lines of the legs 282 and 286 are also aligned with each other, while being offset from the lines articulation of the tabs 280 and 284 a distance typically equal to the thickness or diameter of a support member to be placed between the tabs 280 and 282, and respectively 284 and 286. In the original rest position , the tabs 280, 282, 284 and 286 extend in the thickness of the plate 260 as illustrated in FIG. 9. The tabs 280, 282, 284 and 286 may, however, be folded at 90.degree. of the plate 260 as seen in Figure 13 to form two clevises or stirrups serving as support for any suitable support means, for example an extendable bar 470, back window, placed between the two pairs of legs 280 and 282, respectively 284 and 286.

Preferably each of the tabs 270, 272, 274, 276 and 280, 282, 284 and 286, pre-cut and foldable comprises a through hole for the passage of a fastening means, for example a threaded element.

Fig. 10 shows the use of a support plate 260 shown in Fig. 9 glued to a reflector plate 100 for attachment to a balcony railing B. More precisely according to FIG. 10, the tabs 270 and 272 are fixed on a U-shaped crosspiece 480 itself fixed on calipers 310 equivalent to those shown in the preceding figures.

Figures 11 and 12 show the feasibility of the transom 480 and brackets 310 from single blades 480, 312, 313 initially planar and bent in situ manually on demand depending on the particular implantation conditions.

The transom 480 and the stirrups 310 may be subject to numerous variants. Those shown in Figures 10 to 12 will therefore not be described in more detail later.

Likewise, the extendible bar 470 shown in FIG. 13 can be the subject of numerous variants and will therefore not be described in more detail below.

The attached figure shows the possibility, in the context of the present invention, of producing the support means of the plate 100. reflector forming a base, such as a base which itself supports a plate 260 of the aforementioned type. Here again the concrete realization of this base can be the subject of many embodiments and will therefore not be described in more detail later.

The embodiments according to the present invention shown in the appended FIGS. 14 to 29 will now be described to illustrate the possibility, in the context of the present invention, of producing the support box 200 in discontinuous form, for example in the form of two support blades. 290 folded supporting areas remote from the plate 100 which forms reflector.

The inventors have indeed also determined that such an embodiment of a discontinuous box formed from two blades 190 folded and each fixed at two separate points on a common face of the reflector plate 100 allows on the one hand in a transverse direction to form a triangulation, by the geometry of each folded blade 190, and secondly a stiffening in the longitudinal direction resulting from the attachment of the two blades on a workpiece, and therefore a box configuration 200 adapted to provide the required rigidity for the reflector plate 100.

Preferably, as can be seen in the comparative examination of FIGS. 16 and 17, as well as in FIGS. 14, 15, 17 and 25 to 29, each blade 290, initially flat, is folded around 3 folding lines 292, 294 and 296 parallel to each other and transverse to the direction of elongation of the blades 290 to form two end fins 291 and 297 interconnected by two intermediate wings 293 and 295.

The two end fins 291 and 297 serve to support and fix the reflector plate 100. They are coplanar after folding. They are preferably provided with sizing strips for fixing the folded blades 390 by gluing on the rear face of the reflector plate 290 as seen in FIGS. 14, 15, 21 to 24 and 29. The intermediate fins 293 and 295 form a triangulation. They are preferably of different lengths. They can be used to fix the set according to the configuration adopted directly or indirectly on an element related to the shell of the building.

There is shown in Figure 14 an application in indoor wall mounting. In this case preferably the blades 390 are fixed on the shell by the fins 293 of shorter length, generally transverse to the mean plane of the reflecting plate 100.

More precisely still according to the embodiment shown in Figure 14 in this case the fin 293 cooperates with a support block 2900 itself intended to be fixed on the shell.

Such a support block 2900 can be the subject of many embodiments. It will not be described in detail later.

According to the embodiment illustrated in FIGS. 14 and 18 to 20, such a support block 2900 is made in a cage by folding an initially plane blade around four folding lines parallel to each other 2902, 2904, 2906 and 2908 delimiting 5 platelets 2901, 2903, 2905, 2907 and 2909. After folding the two end plates 2901 and 2909 are coplanar and parallel to the middle plate 2905, while the two intermediate plates 2903 and 2907 are perpendicular to the aforementioned plates 2901, 2909 and 2905. The block then constitutes a cage of square or rectangular cross-section in which the middle plate 2905 is intended to rest against the shell and to be fixed thereto by any appropriate means, for example by threaded means, the pads Intermediates 2903 and 2907 serve as a spacer and the coplanar plates 2901 and 2909 hold the fin 293. For this purpose, for example, said fin 293 may be provided with two parallel slots 2931 and 2932 in which the plates 2901 and 2909 are engaged before being folded on the inside of the fin 293.

The middle plate 2905 may be provided with suitable through-holes 2950, 2951, 2952 for cooperation with any suitable fastening means, for example threaded fastening means on a larger scale. for example cooperating for example with a central oblong slot 2951 for wall mounting (see FIG. 21), and / or suction cup type fixing means 2954 cooperating, for example preferably with two lateral orifices 2950 and 2952 (see FIG. 22). Where appropriate the outer face of the middle plate 2905 may also be provided with an adhesive for attachment to a suitable support.

FIG. 15 shows a roof window mounting application in which the blades 390 are fixed by means of the long fins 295, generally parallel to the mean plane of the reflecting plate 100, while being inclined by relative to this average plane, on suitable support blocks 2940 globally equivalent to the aforementioned blocks 2930.

These support blocks 2940 can be the subject of many embodiments and will not be described in detail later.

As indicated above, FIGS. 21, 22 and 23 show three alternative implantation variants of the means illustrated in FIGS. 14 to 20, respectively in wall fixing (FIG. 21 by means of threaded means engaged in the oblong slots 2951 of the middle plate 2905. attached to the shell), attachment by suction cup (Figure 22 through suction cups 2954 held in the orifices 2950 and 2952) and fixing on a shelf (Figure 23 the fin 295 resting on the upper face of the tablet).

FIG. 24, similar to FIG. 21, illustrates the possibility of angular adjustment of the reflector plate 100 by controlling the folding of the support blades 290. More precisely, FIG. 24 shows the possibility of adjusting the inclination of the reflector plate 100 by controlling the relative inclination of the fins 291, 295 and 297 relative to the support fin 293 and thereby the distance separating the two glued end fins 291 and 297 which remain coplanar to support the reflector plate 100.

Figures 25 to 29 show an alternative embodiment of the support blocks 2900 in wall application. Here again these support blocks 2900 can be the subject of many embodiments and will therefore not be described in detail later.

It will be observed that according to the embodiments illustrated in FIGS. 14, 15 and 17, the fin 291 is folded towards the inside of the blade 290, whereas the fin 297 is folded towards the outside of the blade 290. ci, while according to the embodiments illustrated in Figures 21 to 29 the two wings 291 and 297 are folded outwardly. Alternatively the two fins 291 and 297 could be folded inward or the fin 291 folded outwardly while the fin 297 would be bent inwards.

Those skilled in the art will understand that the realization of the support means of the reflective plate 100 by manual folding to bring out the support functions in situ on demand and according to the precise conditions of implantation from tabs pre-positioned by laser cutting in the mass of a plate 260 or support blade 290 allows an initial reduced volume plan conditioning, and a simple assembly without special tools within the reach of any speaker.
