Definitions

• the present invention relates to a rolling curtain, in particular a transparent rolling curtain. More specifically, it relates to a rolling curtain of the type comprising an apron composed of horizontal blades hinged together and which winds on a shaft or upper horizontal drum, the edges of the hinged apron moving in lateral guides or slides.
• Such rolling curtains are generally called to be shaped and arranged to constitute shutters or similar closures, or partition walls, or portions of walls, or complete walls of certain premises.
• Such curtains allow the sight and passage of light from the inside to the outside and / or from the outside to the inside, even when the transparent rolling curtain is in the lowered position.
• This type of transparent rolling curtain can be applied:
• FR-2945313 discloses a transparent security curtain composed of a plurality of flat horizontal transparent blades, refitted together in an articulated manner. Each flat blade is formed of a plurality of modules abutted one after the other. It is further connected, in an articulated manner, to that which is immediately higher or lower through two different complementary junction profiles equipping the adjacent edges of two adjacent blades and interlocked into one another. Finally, a breakable locking tip is positioned at the end of each plate to stabilize the system.
• the iames consist of abutting modules and are assembled together by superimposing their ends, which creates the formation of a large number of opaque areas unattractive and reducing visibility.
• Document FR-2,941,989 describes a roller shutter blade comprising a solid core, consisting of a transparent or translucent material, covered on a part of each of its two faces, with a coating consisting of an opaque material, this coating being placed on the posterior face and on the anterior face of said core, so that an incident light ray can not cross said blade from one side without being stopped by at least one of the two coatings.
• Said blade has a generally curved cross section without any precision being provided on the interest of this provision.
• the rolling shutter blade has a curved outer surface and according to a preferred embodiment, the two surfaces of the core are concave. It is intended to vary the shape of the blade and in particular the shape of the soul according to the amount of light that the skilled person wishes to see transmitted through said blade. This is the unique function devolved to this Form.
• 3ans document FR-2,643,938 describes a transparent safety roller shutter consisting of a plurality of horizontal flat blades hinged together by means of hinges.
• the apron of this roller shutter can be wound on a drum.
• the winding obtained is irregular and requires a very bulky box for housing the rolled curtain.
• the means of joining articulated blades together seriously complicate the replacement of one or more thereof when necessary.

Said heads can be introduced into the receiving grooves of the coupling profiles and are held there with the possibility of pivoting.
• GB-2,120,306 discloses a rolling protection grid formed of a series of transparent blades made in one piece and extending horizontally and metal rods pivotally connected to one another by means of ribs preferably Circulars extending along the upper and lower edges of each blade, which are received within the sleeves formed in the metal of the rods.
• blades made in one piece have a low impact resistance, making the transparent curtain very fragile.
• the method of manufacturing, transporting and mounting such blades, which generally have long lengths (of the order of 2 to 7 meters) is complex and expensive.
• the document EP-0,445,064 describes a safety grid comprising several parallel rows of profiles, between each section there is a plurality of elements made of transparent plastic material, and preferably of polycarbonate, these elements being separated by intermediate reinforcing elements made for example of aluminum.
• the grid comprising a plurality of polycarbonate elements, the reinforcing elements being made of aluminum, they are therefore opaque which alters the transparency of the grid, particularly in the embodiment where the aluminum elements have the same dimensions as the polycarbonate elements.
• the document FR-2,955,885 describes a roller shutter element consisting of an assembly of rows of modules where each module is of generally rectangular shape and whose long sides are parallel to the winding axis of said flap and where the modules of the same row are interconnected by means of a bar or circular section tube passing in hinges which are provided with said long sides.
• two adjacent modules are contiguous at their small sides and one of the short sides of a module is provided with a lip overlapping the short side of the adjacent module.
• the assembled ends with single overlap or by hooking are complex and not very compatible with a transparent curtain since they create extra thicknesses and vertical zones of non transparency preventing a perfect visibility and forming unsightly darkened surfaces and which, moreover, have the disadvantage of not offering a complete hermeticity to the air, the water, the hot and the cold.
• US-6,263,943 discloses a modular roller shutter for the doors and showcases stores, consisting of a plurality of rows of blades. Each blade is bonded by means of loops to a lower blade and an upper blade, allowing limited movement of the blades and loops so that the modular roller shutter can be rolled up and unrolled.
• Each blade may consist of a plurality of lamellae having reinforcements at their ends. In order to connect the adjacent lamellae, each reinforcement is provided with a coupler, the adjacent couplers having complementary forms of coupling allowing the interconnection of two adjacent lamellae.
