The present invention relates to a solar shading device.

modular louvres

  orientable used in particular on the facade or inside a building.

  It is known in the prior art, in particular in French patents FR 1 493 494, FR 1 530 512, FR 2 735 519, sunshades made of orientable blades mounted parallel on a frame and whose orientation is modifiable by through a manual or electric device. In particular, patent FR 1 530 512 teaches sunshade blades

  made up of a monobloc profile comprising a pivot axis.

  The disadvantage of this type of sunshade is that their appearance is uniform. It is not possible to form a blade, the two faces of which are made of different materials. In addition, when any part of a blade is

  damaged, it is necessary to replace the blade completely.

  The present invention therefore relates to a louvre sunshade

  15 modular to overcome the drawbacks of the prior art.

  This object is achieved by the fact that the modular blade sunshade comprises a structure comprising parallel beams between which is mounted at least one blade and is characterized in that each blade comprises on the one hand, at least one pair of flanges pivotally mounted between two beams and on the other hand, a plurality of profiles, these profiles being mounted

  on each pair of flanges by means of securing means.

  According to another particularity, each blade comprises at least two end profiles and at least one connection profile mounted between the profiles

end to form the blade.

  According to another particularity, at least one connection profile consists of a determined material different from the material constituting the other profiles of

the blade.

  According to another particularity, each connection profile comprises positioning means intended to ensure an adequate positioning of

  each connection profile when they are joined to the pair of flanges.

  According to another particular feature, each connection profile comprises

reinforcement means.

  According to another particular feature, the reinforcing means consist of at least one strip integral with the connection profile and perpendicular to the longitudinal plane of the blade. According to another particularity, the means for securing the plurality of profiles and a pair of flanges comprise a plurality of holes made in each flange and intended for the passage of screws or rods which collaborate with means of fixing each profile for the

io join with the flanges.

  According to another feature, the material constituting at least one profile

  bond is selected from wood, or aluminum.

  According to another particular feature, the dimensions of the end profiles are chosen to allow the assembly of width link profile

different.

  Other features and advantages of the present invention

  will appear more clearly on reading the description below made in

  reference to the accompanying drawings in which: - Figure 1 shows a top view of the sun screen according to

the invention.

  - Figures 2A and 2B respectively represent a top view

and a front view of a flange.

  - Figure 3 shows a cross-sectional view of two profiles

  of constitution of a blade before the final assembly of the blade.

  - Figures 4A to 4C show a cross-sectional view of

  several alternative embodiments of a blade according to the invention.

  To better understand the technical characteristics of the invention,

  the present description is made for a modular louvre sunshade

  comprising two end profiles and two connection profiles. However, it is within the reach of the skilled person to imagine a different configuration without departing from the concept of the invention. Likewise, the general shape chosen for the blades corresponds to the shape usually chosen for a solar shading blade, but other shapes can be adopted. These particular choices of configuration and shape are given for illustrative purposes only and do not constitute

not a limitation of the invention.

  Figure 1 shows a top view of the sunshade according to the invention. The sunshade according to the invention comprises blades (1) mounted

  on a structure (4) by means of a pair of pivoting flanges (3).

  To do this, each flange (3) comprises an axis (31) coincident with the pivot axis of the blade (1). This axis (31) is mounted to rotate freely in a sleeve (41) integral with a spar (40) of the structure (4). The angle between the axis (31) of each flange and the longitudinal axis of the structure is substantially equal to 90. Advantageously, the structure (4) can be arranged horizontally or vertically with respect to the ground. Figure 1 shows only one blade. However, the sunshade may include several blades (1) as shown in Figure 1 and arranged parallel to each other, between two beams (40) of the structure (4). The distance

  between two longitudinal members (40) of the structure is chosen by the user.

  Simultaneous actuation of the blades (1) disposed between two side members (40), is ensured by an operating member (not shown) consisting for example of at least one rod, or a cable secured to one end d '' at least one flange (3) of each blade (3). In known manner, the operating member can be actuated manually or electrically. According to the invention, each blade (1) comprises a plurality of profiles (10, 20) mounted between two flanges (3). Advantageously, each blade (1) comprises at least two end profiles (20) and at least one connecting profile (10) located between the

end profiles (20).

  FIGS. 2A and 2B respectively represent a front view and a top view of a flange. The general shape of the body section (30) of a flange (3) is substantially a flattened ellipse. However, others

  flat shapes are possible depending on the wishes of the user.

  The axis (31) allowing the blade to pivot consists of a first

  cylindrical projection disposed in the center of the section of the flange body (30).

  The body (30) also includes a plurality of holes (34) for

  ensure the mounting of screws or rods for fixing each profile on the flange (3).

  As described above, the blades can be actuated by means of an operating member. This operating member is made integral with one end of the flange by means of a second projection (32)

  comprising for example a hole (33).

  FIG. 3 represents a cross-sectional view of the two constituent profiles of a hollow blade before the final assembly of the blade. In o10 the example of a blade described below, a blade consists of two end profiles (20) and two connecting profiles (10). The general shape of the profiles (10, 20) is that of a V-shaped section whose angle is rounded. This shape is such that once mounted between two flanges the cross section of the blade has the same shape as the flange. In our embodiment, this shape is a flattened ellipse. Thus, the cross section of the end profiles (20) corresponds to the shape of the ends of the ellipse and the cross section of the connecting profiles (10) to the shape of the sides of the ellipse. Each profile (20)

  end also includes means (21) for fixing on a flange.

  These fixing means (21) consist, for example, of gutters (21) whose axis of symmetry is parallel to the longitudinal axis and, for example, the same length as the end profile (20). These gutters (21) are integral with the support (23) perpendicular to the longitudinal plane of the end profile (20). These supports (23) also constitute reinforcements of the end profile (20). Advantageously, the length of the gutters (21) corresponds to the

  length required for fixing the end profile (20) on the flange (3).

  When mounting each end profile (20) on a flange (fig. 2, 3), the gutters (21) are intended to receive, for example, screws (not shown) which have previously passed through the holes (34 , fig. 2B) of the flange. The end profile (20) also comprises means (22) for mounting with the connecting profiles (10). These mounting means, for example, consist of housing (22) in the shape of a U in which comes to fit, during their assembly one of the ends (11) of a profile (10) of connection. These housings (22) are arranged in pairs so that each free end of the end profile (20) is merged with a branch of a U forming a housing (22) and to constitute a housing for each connection profile of each face. The connecting profiles (10) comprise means (12) for fixing to a flange. These fixing means (12) are, for example, similar to the means (21) for fixing the end profiles (20), and consist of gutters (12) integral with the support. Advantageously, each profile (10) of the connection comprises means (13, 14) for positioning. When the connection profiles (10) are assembled on the end profiles (20), the first means (13, 14) for positioning a first connection profile will fit into the second means (13, 14) for positioning a second connection profile to ensure the correct assembly of the connection profiles (20). To do this, the means (13, 14) for positioning a connection profile (10) comprise at least one strip (13, 14) integral with the connection profile (10) and perpendicular to the longitudinal axis of the blade (1) whose end is of determined shape. This shape is determined so that the shape of the end of each strip (13) of a first profile (10) connecting a face of the blade is complementary to the shape of the end of each strip

  (14) of the second profile (10) connecting the opposite face of the blade.

  Advantageously, these positioning means (13, 14) are integral with the supports of the gutters (12) for fixing and disposed at a distance from the inner profile face corresponding to the half thickness of the blade (1) at this

place.

  Figures 4A to 4C show a cross-sectional view of several alternative embodiments of a blade according to the invention. The modularity of the blades (1) of the sunshade according to the invention makes it possible to assemble blades (1) whose material, color and / or texture of the sides, of the profiles (10) of connection, can be different from the material, and / or color and / or texture of the end profiles (10). Similarly, the material, and / or the color and / or the texture of a first side of the blade (1) may be different from the second side. Figure 4A shows a cross-sectional view of an alternative embodiment or the material chosen for all of the profiles (10, 20) constituting the blade (1) is identical and is preferably aluminum. However, the color and / or texture of the different profiles (10, 20) is not necessarily uniform. In this variant, the fixing means (12) are separated from the positioning means (13, 14). In addition, reinforcing means (15) make it possible to stiffen the blade (1), for example at its center, and to increase its resistance to creep. These reinforcing means (15) consist, for example, of a strip (15) integral with the profile (10) of connection and perpendicular to the longitudinal plane of the blade (1). The end of the strip (15) is, for example, in the form of a hook so that when the connection profiles (10) are assembled, each strip (15) of the connection profiles (10) is

  i5 secured, by hooking to form a reinforcement.

  FIG. 4B represents a variant in which the material chosen to constitute one of the connecting profiles (100), es, for example, wood. Given the mechanical properties of this material, some adaptations are

  carried out to allow the assembly of the wooden connecting profile (100).

  In particular, the particular choice of wood eliminates the means (12) for fixing on the flanges of this profile (100). Indeed, the joining of this profile (100) of wooden connection with the flanges is carried out simply by screwing the fixing screws directly into the wood. The means (15) for reinforcing the aluminum connection profile (10) engages in a groove (115) formed in the wooden connection profile (100) in order to ensure the

blade reinforcement (1).

  FIG. 4C represents an alternative embodiment for which the material chosen to constitute the connecting profiles (100) is, for example, wood. For the reasons mentioned above, the means for fixing the connection profiles (100) are eliminated. In addition, the positioning means and the reinforcement means are also eliminated. Unlike the aluminum connection profile (fig. 4A, 10) (or other metal or similar alloy), which is substantially in the form of a metal sheet, the wooden connection profiles (100) are as a bar, which gives these profiles

  (100) an intrinsic rigidity which it is not necessary to reinforce.

  The profiles (100) also include notches (101) which allow the reception of the ends of the U-shaped housings (22),

end profiles (20).

  It is understood that the modular louvre sunshade allows to consider new configurations for building layout. Indeed, the main function of a solar shading is to reflect the outside light. The reflecting surfaces must therefore be made of a material and a color suitable for fulfilling this function. However, the materials and colors, adapted to fulfill this function, are not very aesthetic. Indeed, it is generally aluminum painted with light colors. Some sunshades, favoring aesthetics, are made of varnished wood. However, prolonged exposure of a varnished wooden surface necessarily results in deterioration of the varnish which must therefore be maintained periodically. The sunshade according to the invention makes it possible to advantageously combine the efficiency of the reflective surfaces of painted aluminum and the aesthetics of wood. Indeed, it suffices for this that the connection profile intended to reflect light is, for example, painted aluminum and that the connection profile directed towards the interior of the building

  either, for example, wood or any other decorative material.

  In addition, as regards the manufacture of the profiles of the blades, a judicious choice of dimensions for an end profile advantageously allows its assembly with connection profiles of different width, it being understood that for a determined blade the connection profiles have the same dimensions. The manufacturing costs are therefore lower since, for different blade widths, the end profiles are identical. Finally, when a blade is damaged, it is sufficient to replace the damaged blade profile (s), which

  considerably reduces the maintenance costs of the sunshade according to the invention.

  It is clear that other modifications within the reach of those skilled in the art fall within the scope of the invention.
