OCCULTATION CURTAIN FOR ROLLING SHUTTER EQUIPPED WITH A HIGH RIGID STOP.

FR 3 058 444 - A1 (57) The object of the invention relates to a blackout curtain (1) for a rolling shutter, comprising in particular a final blade (2f) equipped with a high stop defining the open position full curtain. The curtain comprises, as a high stop, a finishing blade (6) which covers the final blade by presenting at least one lateral blocking extension (8), this finishing blade being provided over at least part of its length, d 'A hook (16) engaged in support on both sides in a housing (17) of the final blade of the curtain.

The present invention relates to the technical field of rolling shutters with slats intended to ensure the concealment of a bay in the general sense.

Conventionally, a rolling shutter comprises a series of blades or horizontal slats hinged together to form a blackout curtain. This curtain has on one side, an end blade intended to be connected to a drive drum, and on the opposite side, a final blade intended to come into abutment up to a low stop in the position of complete concealment of the curtain. Conventionally, this curtain is guided in slides, in vertical sliding down to a low stop to occupy a full concealment position and in vertical sliding up to occupy a partial or full opening position in which the blades are wrapped around of the drum.

To define the fully open position of the curtain, the final blade of this curtain is equipped with a so-called high stop intended to come into contact with the chassis of the roller shutter. In practice, the mounting of this stop on the final blade proves to be difficult to carry out in order to present a rigid connection which withstands the repeated efforts of locking in winding while not weakening the rigidity of the final blade on which is mounted. this stop.

The present invention aims to remedy the drawbacks of the prior art by proposing a new blackout curtain for rolling shutters, the high stop of which has high mechanical strength while not affecting the rigidity of the final blade on which the high stop. is fixed.

Another object of the invention is to provide a blackout curtain that can be easily fitted in the first or second fitment, with a high stop.

To achieve such objectives, the blackout curtain for rolling shutters, comprises a series of superimposed blades hinged together, and having on one side, an end blade intended to be connected to a drive drum, and opposite side, a final blade fitted with a high stop defining the fully open position of the curtain. According to the invention, the device comprises, as a top stop, a finishing blade which covers the final blade by presenting at least one lateral blocking extension, this finishing blade being provided over at least part of its length, d 'A hook engaged in support in a housing of the final blade of the curtain, the finishing blade being assembled to the final blade by fixing members.

The blackout curtain according to the invention also comprises in combination one and / or the other of the following additional characteristics:

- The final blade has at its external edge, a C-shaped profile defining the housing for receiving the hook;

- The final blade has at its external edge, a core from which rise two wings extending by returns oriented towards each other to define a passage opening for the hook;

- The finishing blade comprises a sole provided opposite its bearing face, with a hook comprising a leg rising from the sole and ending in a curved part;

- the curved part of the hook is engaged in support between the core and a return of the final blade;

- the sole of the finishing blade is fitted on the side of the bearing face with a seal;

- The fasteners are mounted to partially pass through the seal;

- The finishing blade has two cheeks rising from the sole to extend on either side of the final blade, the cheeks extending at right angles by lateral blocking extensions;

- the lateral blocking extensions have different widths.

Another object of the invention is to provide a rolling shutter comprising a blackout curtain according to the invention, guided in sliding in vertical slides and driven by a drive drum, in vertical sliding down to a stop. low to occupy a position of complete concealment and in ascending vertical sliding to occupy an open position characterized in that the curtain is provided with a finishing blade extending with play, between the vertical slides.

Various other characteristics will emerge from the description given below with reference to the appended drawings which show, by way of nonlimiting examples, embodiments of the subject of the invention.

Figure 3 is an exploded perspective view showing the mounting of a high stop according to the invention on the final blade of a blackout curtain.

Figures 4 to 7 are sectional elevation views showing the different stages of mounting the upper stop according to the invention on a final blade.

As shown in Figs. 1 to 3, the object of the invention relates to a blackout curtain î for a rolling shutter V comprising a series of horizontal blades 2 hinged together to form the blackout curtain ί of which only the final blade 2f has been shown completely on the drawings. This blackout curtain 1 is guided on both sides, sliding in vertical slides 4. This blackout curtain 1 has, opposite its final blade 2f, an end blade driven by a drum d training not shown but known per se. This drum drives the curtain 1 in vertical sliding down to a bottom stop to occupy a complete concealment position and in vertical sliding up to occupy an open position. This drum is rotated using a manual or motorized control to ensure the upward and downward sliding of the blackout curtain 1.

The drum and the slides 4 are not described more precisely because they are well known to those skilled in the art.

In a known manner, the final blade 2f has an external face 2e and an internal face 2i which are parallel to each other and connected by an external edge 2c extending opposite to the internal edge from which this final blade is articulated to the neighboring blade 2. This final blade 2f is equipped with a high stop 6 having at least one part extending laterally or projecting from at least one face 2i, 2e of the blade so as to be able to cooperate with the chassis of the roller shutter and in particular with the shutter underside of the box containing the winding drum, when the curtain occupies its fully open position.

In accordance with the invention, the curtain 1 comprises, as a top stop, a finishing blade 6 coming to cover the final blade 2f and having at least one lateral blocking extension and in the example illustrated, two lateral blocking extensions 8. Each lateral blocking extension 8 is intended to come into abutment against the frame of the rolling shutter and more precisely against the shutter underside of the box containing the winding drum, when the curtain occupies its fully open position. Thus, when the curtain 1 slides vertically upwards, the latter is blocked in its fully open position, by the abutment of the lateral blocking extension or extensions 8 with the chassis of the roller shutter.

As shown more precisely in FIGS. 1 and 3, the finishing blade 6 is fitted onto the final blade 2f from its external edge 2c. The finishing blade 6 comprises a C-shaped profile having a sole 10 having externally, a bearing face 11 intended to come into contact with the bottom stop defining the position of complete concealment. From the sole 10 rise substantially perpendicularly, two cheeks 13 delimiting between them a housing 14 for the insertion of the final blade 2f. In the mounted position, the cheeks 13 extend on either side of the final blade, over part for example of the height of this final blade.

Of course, the finishing blade 6 has a length less than the final blade 2f to allow the curtain to slide between the slides

4. As shown more precisely in FIG. 2, the finishing blade 6 has a length less than the distance separating the two slides 4 in order to leave a clearance between each end of the finishing blade 6 and the neighboring slide 4.

According to a preferred embodiment characteristic, at least one cheek and in the example illustrated, each cheek 13 is extended at right angles by a lateral extension 8 oriented towards the outside of the finishing blade, that is to say outside the housing 14. Advantageously, the lateral blocking extensions 8 have different widths taken between the end edge of these extensions and the adjacent cheek 13. This asymmetrical shape of the finishing blade 6 allows a reversible mounting suitable for ensuring in position d 'full opening of the curtain, closing the space of the window for passage of the curtain 1 defined at the underside of the shutter of the box containing the winding drum.

According to an advantageous characteristic of embodiment, each lateral extension 8 projects internally beyond the cheeks 13, at the level of the housing 14, by a return 8 _t coming to bear on the external 2nd and internal faces 2i of the final blade 2f. The distance between the interior returns 8i of the cheeks is adapted to ensure a tightening of the final blade 2f fitted into the housing 14 of the finishing blade 6.

This finishing blade 6 is provided over at least part of its length, with a hook 16 engaged in support on either side in a housing 17 of the final blade 2f of the curtain. As shown more precisely in FIGS. 3 and 4, the sole 10 of the finishing blade 6 is provided with the hook 16 rising from the internal face 18 situated opposite its bearing face 11. More specifically, the hook 16 has a leg 16a rising at right angles from the internal face 18 of the sole and ending in a curved part 16b extending substantially perpendicular to the leg 16a. According to an advantageous characteristic of embodiment, the hook 16 is produced over the entire length of the finishing blade 6.

The hook 16 is intended to cooperate with the final blade 2f. To this end, the final blade 2f has at its external edge 2c, a C-shaped profile defining the housing 17 for receiving the hook, opening towards the outside of the final blade 2f. The final blade 2f has at its external edge 2c, a core 21 connecting the internal 2i and external 2e faces of the final blade and from which rise in the extension of these faces, two wings 22 extending to the 'square by returns 23 internally oriented towards each other to define therebetween an opening 24 passage for the hook.

Thus, the distance between the free edges of the returns 23 is slightly greater than the width of the curved part 16b of the hook to allow the insertion of this curved part between one of its returns and the core 21 of the final blade 2f (Fig. 6). Thus, the curved part 16b of the hook is engaged in support between the core 21 and a return 23 of the final blade. According to an advantageous characteristic of embodiment, the thickness of the curved part 16b of the hook is equal to the play near, at the distance between the core 21 and a return 23. The curved part 16b of the hook is thus wedged in support by hand and else, in the final slide 2f.

According to an advantageous characteristic of embodiment, the C-shaped profile of the final blade 2f extends along its entire length. A flat support appears between the final blade 2f and the finishing blade 6 ensuring good recovery of the forces exerted on the lateral blocking extensions 8.

Furthermore, the finishing blade 6 is assembled to the final blade 2f by fixing members 28 such as for example fixing screws fixed from the bearing face 11 of the finishing blade 6 to pass through the sole 10 of the finishing blade 6 so as to be anchored in the core 21 of the final blade 2f (Fig. 7).

According to an advantageous alternative embodiment, the finishing blade 6 comprises, on the side of the bearing face 11, a seal 29 partially engaged inside a groove 30 arranged in the bearing face

11. As is clear from FIG. 7, it should be noted that the fixing members 28 partially pass through this seal 29 to find themselves partly hidden.

The mounting of a finishing blade 6 on a final blade 2f of a curtain is relatively simple to carry out since it suffices to fit the finishing blade 6 at the lower end of the curtain so that the hook 16 comes to anchor the final blade 2f by the engagement of the curved part 6b between the core 21 and a return 23 of the final blade 2f. The final assembly between the finishing blade 6 and the final blade 2f is ensured by screwing the fixing screws 28 distributed along the finishing blade 6.

The invention is not limited to the examples described and shown since various modifications can be made without departing from its scope.
