In the figures is illustrated an independent or autonomous ventilation device 1 for an opening 2 arranged through a vertical wall 3 of a building, which has one side facing outward EXT and one side facing inward INT of a room in the building.

As illustrated in particular in FIG. 3, on the interior side INT, the wall 3 is equipped with an opening 4, for example a window, capable of closing / opening the opening 2 of the building and opening towards the inside, opening 2 presenting a table outside window 4.

As illustrated in particular in FIGS. 1 and 2, the wall 3 is also equipped with a shutter system 5 which comprises an apron 6, capable of obscuring the opening 2 of the building, formed of a plurality of longitudinal horizontal slats 7 connected together by articulations and comprises an upper winding / unwinding means 8 mounted in a box 9 arranged above the opening 2 of the building, in the wall 3.

The shutter system 5 comprises a winding / unwinding means 8 comprising a longitudinal horizontal axis 10 to which is fixed an upper end of the deck 6. The rotation of the axis 10 can be controlled either manually, for example by a crank or a strap, either by an electric motor.

When the axis 10 is rotated in one direction or the other, the deck 6 can be rolled up or unwound so that a deployed vertical portion 6a of the deck 6, extending downwards inside the opening 2 of the building and outside relative to the opening 4, can go up or down, the deck 6 passing through a lower slot 11 of the trunk 9.

To guide the upward and downward movements of the deployed portion 6a of the deck 6, the flap system 5 comprises opposite vertical slides 12 and 13 fixed against opposite vertical sides 14 and 15 of the table of the opening 2 of the building. The vertical slides 12 and 13 are formed by profiles of U-shaped sections, opposite, between the opposite wings of which the ends of the horizontal blades 7 are engaged and can slide.

The ventilation device 1 is mounted and maintained in the lower part of the opening 2 of the building, outside with respect to the opening 4, above a lower flange 16 of the table of the opening 2 of the building and between the opposite sides 14 and 15 of the opening 2 of the building.

The ventilation device 1 comprises a longitudinal box 17 which extends above the lower edge 16 of the opening 2 of the building and below the deployed part 6a of the deck 6 of the shutter system 5.

The longitudinal box 17 comprises a peripheral longitudinal wall 18, which delimits an interior space of substantially square or rectangular section, and transverse end walls 19 and 20 which are located at short distances from the opposite sides 14 and 15 of the opening 2 of the building and the vertical slides 12 and 13.

The peripheral longitudinal wall 18 of the box 17 comprises a horizontal lower wall 21, a vertical internal wall 22 on the internal side INT, a vertical external wall 23 on the external side EXT and a horizontal upper wall 24.

For example, as illustrated in particular in FIGS. 3, 4 and 5, the longitudinal box 17 is formed by two parts, a first part 17a of which comprises the horizontal bottom wall 21, the vertical interior wall 22 and the transverse end walls 19 and 20 and a second part 17b of which comprises the vertical outer wall 23 and the horizontal upper wall 24, these parts being coupled by conjugation of shapes and by fixing screws (not shown). Advantageously, the vertical outer wall 23 and the horizontal upper wall 24 form a rounded shape between them.

The longitudinal box 17 is equipped with support legs 25 suitable for or arranged to bear support above the lower edge 16 of the opening 2 of the building. The support feet 25 are adjustable vertically with respect to the longitudinal box 17. The support feet 25 are mounted on the horizontal lower wall 21 of the longitudinal box 17.

For example, as illustrated in particular in FIGS. 5 and 7, each support leg 25 comprises a nut 26 fixed on the bottom wall 21 of the longitudinal box 17, advantageously against its inner face, and a vertical threaded rod 27 which is engaged through the nut 26 and which passes through this lower wall 21. The lower end of the vertical threaded rod 27 is provided with a support head 28 bearing on the lower rim 16 of the opening 2 of the building .

Advantageously, one can provide four support feet 25 spaced two by two transversely and longitudinally and respectively close to the transverse walls 19 and 20 of the longitudinal box 17.

By vertically adjusting the threaded rods 27 relative to the nuts 26, the vertical position of the longitudinal box 17 is adjusted relative to the lower edge 16 of the opening 2 of the building and its horizontality.

The longitudinal box 17 is equipped with fixing means 29 suitable for or arranged to cooperate with the opposite vertical sides 19 and 20 of the opening 2 of the building and / or with members mounted on these opposite sides 14 and 15, for example the vertical slides 12 and 13.

The fixing means 29 are coupled to the ends of the longitudinal box 17.

The fixing means 29 are adjustable longitudinally and / or transversely relative to the longitudinal box 17.

The fixing means 29 are suitable for or arranged to act by wedging longitudinally and / or transversely with respect to the longitudinal box 17 so as to cooperate by pressing with the opposite vertical sides 19 and 20 of the opening and / or with mounted members on the opposite sides 14 and 15 of the opening 2 of the building, for example the vertical slides 12 and 13.

Advantageously, the fixing means 25 are mounted on the transverse end walls 14 and 15 of the longitudinal box 17.

For example, as illustrated in particular in FIGS. 6 and 7, the fixing means 29 respectively comprise intermediate members constituted by vertical portions of opposing intermediate positioning profiles 30 of U-shaped section, which are arranged longitudinally at the outside of the transverse end walls 19 and 20 of the longitudinal box 17 and respectively straddling one of the opposite wings of the vertical slides 12 and 13.

The fixing means 29 comprise longitudinal pressure screws 31 which pass freely through holes 32 arranged through transverse end walls 14 and 15 and which are engaged in threaded holes 33 arranged through connecting branches 33, connecting their opposite wings, profiles 30.

By screwing the screws 31, from the inner sides of the transverse end walls 14 and 15, the ends of the pressure screws 31 come to bear, longitudinally to the box 17, on the edges of the corresponding opposite wings of the vertical slides 12 and 13 and the profiles 30 are pressed against the outer faces of the transverse end walls 14 and 15, thereby exerting opposite longitudinal forces for wedging the longitudinal box 17 between the slides 12 and 13.

Advantageously, the length of the sections 30 is substantially equal to the height of the longitudinal box 17 and the fastening means respectively comprise two pressure screws 31 spaced apart vertically, which pass through two holes 32 arranged through the transverse end walls 14 and 15 and spaced vertically.

Advantageously, the holes 32 arranged through the transverse end walls 14 and 15 are oblong transversely to the longitudinal box 17 so as to allow the longitudinal box 17 to be adjusted horizontally, that is to say perpendicular to the opening 2 of the building or vertical slides 12 and 13.

The pressure screws 31 are provided with locking locknuts 34 capable of coming to bear against the internal faces of the transverse end walls 14 and 15 of the longitudinal box 17.

To set up the longitudinal box 17, one can proceed as follows.

The parts 17a and 17b of the longitudinal box 17 are separated.

The support feet 25 are mounted on the part 17a.

The fixing means 29 are removed.

The profiles 30 are installed on the vertical slides 12 and 13.

The part 17a of the longitudinal box 17 is slid between the profiles 30.

The pressure screws 31 are put in place through the transverse end walls 14 and 15 of the longitudinal box 17 and through the profiles 30.

The desired vertical position of the longitudinal box 17 is adjusted relative to the lower edge 16 of the opening 2 by operating the support feet 25.

The desired horizontal position of the longitudinal box 17 is adjusted in the opening 2 of the building and between the vertical slides 12 and 13, by moving the part 17a of the longitudinal box 17 relative to the vertical slides 12 and 13 and to the profiles 30 and making slide the rods of the support screws 31 along the oblong holes 32 of the transverse end walls 19 and 20 of the part 17a of the longitudinal box 17.

Then, by the sides inside the box 17 of the end walls 19 and 20, the support screws 31 are maneuvered so as to exert opposite support forces as has been described above so as to obtain the support of the box longitudinal 17, so that the longitudinal box is fixed by wedging between the vertical slides 12 and

13.

Then, the locknuts 34 are maneuvered so as to block the support screws 31. Finally, the part 17b of the longitudinal box 17 is put in place on the part 17a of the latter as it has just been put in place. place, so as to close the longitudinal box 17.

The longitudinal box 17 being installed, the horizontal lower edge of the deployed vertical portion 6a of the deck 6 of the shutter system 5 can, in the low position, be brought into abutment above the upper wall 24 of the longitudinal box 17, so to conceal opening 2 of the building.

It follows from the above that the longitudinal box 17 can be put in place and removed without specific intervention on the wall 3 or the vertical slides 12 and 13.

The fixing means 29 of the longitudinal box 17 may nevertheless have alternative embodiments.

The profiles 30 could be mounted completely astride the vertical slides 12 and 13 or completely between the wings of the vertical slides 12 and 13 and the support screws 31 could, in these cases, come to bear against the bottoms, between their wings opposite, vertical slides 12 and 13.

Fastening means 29 of the longitudinal box 17 could be adapted to or arranged to exert respectively, transversely to the longitudinal box 17, transverse clamping forces by opposite transverse supports on the opposite wings of the vertical slides 12 and 13, from the outside or from the inside of the vertical slides 12 and 13, by means of screws, eccentrics or corners.

Fixing means 29 could be adapted to or arranged to exert respectively, longitudinally to the longitudinal box 17, longitudinal efforts of wedging by opposite longitudinal supports on the opposite sides 14 and 15 of the opening 2 of the building, on one side and / or the other of the vertical slides 12 and 13.

It is also conceivable that fixing means 29 of the longitudinal box 17 are fixed on the vertical slides 12 and 13 and / or on the opposite sides 14 and 15 and / or on the lower edge 16 of the opening 2 of the building, by through penetrating organs such as screws.

As illustrated in FIGS. 1 and 4, the ventilation device comprises, mounted inside the longitudinal box 17, a ventilation unit 35 which comprises a rotary ventilation member 36 provided with fins 37 and an electric motor 38 d drive of this ventilation member 36.

The horizontal box 17 has an exterior opening 39 oriented towards the exterior side EXT and an interior opening 40 oriented towards the interior side INT,

The rotary ventilation member 37, driven by the electric motor 38 in a suitable direction of rotation, is capable of generating a flow of air entering the horizontal box 17 through its external opening 39 and leaving the horizontal box 17 through its opening interior 40.

Thus, when the deployed vertical portion 6a of the deck 6 of the shutter system 5 is, in the low position, in abutment above the longitudinal box 17, so as to obscure the opening 2 of the building, and the opening 4 is open, the ventilation unit 35 is capable of generating a flow of air coming from the outside EXT and penetrating inside INT, under the effect of the ventilation member 36, through the longitudinal box 17 via the external opening 39 which constitutes an air inlet opening and the internal opening 40 which constitutes an air outlet opening, the incoming air flow passing between the lower wall 21 of the longitudinal box 17 and the lower rim 16 of opening 2.

As a result, such an internal movement of air can be particularly useful for cooling occupants inside INT, for example a bedroom, during hot summer periods and at night, when the temperature at outside is lower than the temperature felt inside and when the occupants want the deck 6 to be in the lowered position of obscuring the opening 2 of the building. In addition, it is possible to create inside INT an air circulation entering under the effect of the ventilation unit 35 through the longitudinal box 17 and leaving via the lower slot 11 of the trunk 9 and by convection.

Optionally, the ventilation unit 35 includes an intermediate support and air guide casing 41 mounted inside the longitudinal box 17 and inside which the rotary ventilation member 36 is located. The electric motor 38 can be located inside or outside the housing 36.

The openings 39 and 40 of the longitudinal box 17 give access to the interior of the housing 36 and the housing 41 provides air guidance between the air inlet opening 39 and the air outlet opening 40 .

For example, the axis of rotation of the rotary ventilation member 37 and the fins 37 extends longitudinally to the longitudinal box 17.

The openings 39 and 40 of the longitudinal box 17 can be continuous or discontinuous and can be formed by grids.

Advantageously, the air inlet opening 39 is arranged locally through the bottom wall 21 of the longitudinal box 17. The bottom wall 21 of the longitudinal box 17 is spaced from the edge 16 of the opening 2 of the building to leave an air passage. The air inlet opening 39 is protected against rainwater which thus cannot penetrate inside the longitudinal box 17.

Advantageously, the air outlet opening 40 is arranged locally through the inner vertical wall 22 of the longitudinal box 17 and is oriented directly towards the interior INT.

Advantageously, the previously described adjustment of the longitudinal box 17 is such that the internal vertical wall 22 of the longitudinal box 17 is located as close as possible or in contact with the external side of the horizontal internal branch 4a of the frame of the leaf 4 or with a inner shoulder of the wall projecting from the rim 16 and that the air outlet opening 40 is located at least largely higher than the horizontal inner branch of the frame of the opening 4.

With a view to supplying electrical energy to the electric motor 38, it may be provided that an electric wire (not shown) 5 passes through the bottom wall 21 of the longitudinal box 17 and comes from the bottom edge 16 of the opening 2 of the building .

Since the ventilation unit 35 is reversible, an air flow could be created between the interior opening 40 and the exterior opening 39, so as to extract air from the interior space INT towards 10 l EXT.
