Other characteristics and advantages will emerge from the description of the invention which follows, description given by way of example only, with regard to the appended drawings, among which:

is a perspective view of an anticyclonic protection device illustrating an embodiment of the invention,

is a front view of the anticyclonic protection device visible in Figure 1,

is a section along line III-III of Figure 2,

is a section along line IV-IV of Figure 2,

is a perspective view of a dwelling comprising several openings each equipped with an anticyclonic protection device, and

is a transverse and vertical section of an opening of a building equipped with a cyclone protection device.

According to a configuration visible in Figures 5 and 6, a dwelling comprises several openings 10 each equipped, temporarily, with an anticyclonic protection device 12.

Each opening 10, made in a wall 14, is delimited by an embrasure having an upper face, 10.1, a lower face 10.2 (called a threshold in the case of a door), as well as first and second side faces 10.3, 10.4. Generally, an opening 10 is equipped with a door, a window, a bay window or other comprising at least one opening configured to occupy an open state, in which it communicates the interior and the exterior of the habitation, and a closed state.

Although described applied to a dwelling, the invention is in no way limited to this application and can be used on any type of construction.

According to one embodiment, each anticyclonic protection device 12 comprises a central part 16 having a surface area and a geometry close to those of the opening 10 for which it is intended as well as a frame 18 positioned on at least part of the periphery of the central part 16.

According to one configuration, the central part 16 has a square or rectangular perimeter, like the recess of the opening 10. Of course, the invention is not limited to these geometries.

The frame 18 is in the form of at least one plate comprising a face F18 pressed against the wall 14 in operation. This plate extends over at least three sides of the central part 16. According to one configuration, the frame 18 extends over the entire periphery of the central part 16 (on all four sides).

According to the embodiment illustrated in Figures 1 to 4, the frame 18 is flat. Of course, the invention is not limited to this configuration. More generally, the frame 18 is configured to be pressed against at least part of the exterior surfaces of the construction surrounding the opening 10.

The anticyclonic protection device 12 comprises a temporary connection system 20 to fix it to the construction and keep it pressed against the exterior face of the wall 14.

According to one embodiment, the temporary connection system 20 comprises a multitude of screws being housed in passage holes present in the frame 18 on the periphery of the central part 16 and screwing into dowels present in the wall 14 of the construction , around aperture 10.

Of course, the invention is not limited to this temporary connection system 20 and other solutions are possible. Thus, whatever the temporary connection system 20, it must be easily assembled and disassembled, not have too much impact on the aesthetics of the construction and resist tearing in the event of violent winds.

According to one configuration, the anticyclonic protection device 12 comprises a window 22, having a transparent wall, positioned at the level of the central part 16. By way of indication, the window 22 has an approximately rectangular shape of 32 x 22 cm and its transparent wall is made of polycarbonate with sufficient thickness to resist in the event of impact with an object projected by the wind. This porthole 22 allows you to see the outside and let natural light into the building.

The central part 16 has a domed shape 24, projecting outwards from the construction in operation. This curved shape 24 improves resistance to winds and especially to shocks.

According to one configuration, the central part 16 comprises an upper edge 16.1, a lower edge 16.2 as well as first and second side edges 16.3, 16.4. When the anticyclonic protection device 12 is in place, the upper, lower and side edges 16.1 to 16.4 are positioned approximately in the extension of the upper, lower and side faces 10.1 to 10.4 of the opening 10.

According to this configuration, the domed shape 24 extends between the upper and lower edges 16.1 and 16.2 and has, in vertical section, a curved profile, as illustrated in FIG. 3. In the presence of a porthole 22, the domed shape 24 comprises first and second continuous curvatures on either side of the window 22, the first curvature extending between the upper edge 16.1 and the window 22, the second curvature between the lower edge 16.2 and the window 22.

The central part 16 comprises a first secondary face 26 which extends between the first lateral edge 16.3 and the convex shape 24 as well as a second secondary face 28 which extends between the second lateral edge 16.4 and the convex shape 24. With the exception of the junction zones with the side edges 16.3, 16.4 and the curved shape 24 which can be rounded, the first and second secondary faces 26, 28 are substantially flat.

The first and second secondary faces 26, 28 form with the frame 18 an angle β of between 30 and 90°.

According to a characteristic of the invention, each anticyclonic protection device 12 comprises at least one air vent 30 configured to communicate the interior and the exterior of the construction when the anticyclonic protection device 12 is put in place.

According to one embodiment, for each air vent 30, the central part 16 comprises a through orifice and the air vent 30 comprises a grid surrounded by a peripheral frame, for example circular, connected to the edge of the orifice crossing the central part 16.

Each grid includes a mesh allowing sufficient airflow between the interior and exterior of the construction while preventing wind-blown debris from entering the interior of the construction. As an indication, the mesh of each grid is between 1 and 3 mm.

Each air vent has a section between 5 and 30 cm².

Advantageously, the air vents 30 are positioned on at least one of the first and second inclined side faces 26, 28. The fact of positioning the air vents 30 at the level of the first and second inclined secondary faces 26, 28 makes it possible to limit the risks of the air vents 30 being blocked by flying debris.

According to one arrangement, the anticyclonic protection device 12 comprises four air vents 30, two on each of the first and second secondary faces 26, 28.

According to one embodiment, the anticyclonic protection device 12 is a monolithic part made of composite material with reinforcing fibers. The material chosen must give the anticyclonic protection device 12 a high impact resistance, while limiting its mass to facilitate its installation. By way of example, the anticyclonic protection device 12 is made of composite material or reinforced plastic material.

As an indication, for an opening 10 of the order of 90 x 110 cm, the anticyclonic protection device 12 has a width of 130 cm, a height of the order of 150 cm and a mass of the order of 25 kg .

To be more efficient, each anticyclonic protection device 12 (namely its dimensions, the number and sizing of the air vents 30, the shapes of the domed shape 24, the number of temporary connection systems 20, the sizing of the porthole 22,…) is custom designed according to the dimensions of the opening 10 for which it is intended.

In the event of a hurricane alert, for each opening 10, an anticyclone protection device 12 is positioned at the level of the opening 10 so as to obscure it and fixed to the exterior wall of the construction using the connection systems temporary 20. The inner face of each anticyclonic protection device 12, oriented towards the wall in operation, may include cleats to facilitate its positioning relative to the opening 10. Certain openings of the construction positioned at the rear of the protection devices anticyclonic protection 12 are left in the open state to help balance the pressures between the interior and exterior of the construction.

During the passage of the cyclone, the air vents 30 present on the anticyclonic protection device 12 make it possible to balance the pressures between the interior and the exterior of the construction, to limit the risks of explosion due to a overpressure inside the construction.

The positioning of the air vents 30 on the inclined secondary faces 26, 28 makes it possible to limit the risks of the air vents 30 being blocked by debris carried by the wind.

The curved shape 24 of the central part 16 provides great resistance in the event of impact.

Finally, the presence of the porthole 22 provides natural light in the event of a power cut.
