Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a ventilation system having soundproof properties and installed in a glass door or wall, and consisting of two boxes arranged on either side of said glass door or wall. Such devices ventilate the room while soundproofing the room against external noise.

BACKGROUND OF THE INVENTION The problem of ventilation of rooms with openings such as doorways, windows, etc. while achieving soundproofing has been solved in various ways in the past. In particular, soundproof ventilation systems are known which can be provided both in wall materials and on the glass surfaces of room openings.

Soundproof ventilation systems are also known which consist of one or two boxes made of molded bodies and which are attached to the wall material so as to cover both sides of ventilation holes provided in said wall. This device (e.g. French patent no. 561706)
In this case, from a soundproofing point of view, sound-absorbing material is provided on the one hand in the box and on the other hand on the platform provided for this purpose. In this device, therefore, the air circulation is forced into a non-straight path. In this known device, which has to comply with standards and specifications regarding sound insulation and ventilation, fluid and acoustic physics techniques are used.

Problems to be Solved by the Invention Conventional ventilation devices have had inconveniences for both users and manufacturers. If two different boxes are placed on the outside and inside of the wall, manufacturing costs increase because more equipment is required for manufacturing. In addition, the box must be waterproof against the outside, but must not interfere with the operation of openings, shutters, gratings, and other protective devices.

For the user, i.e. the builder or the intermediary of the renovation work, it is necessary to carry out machining work to provide a platform for receiving the attachment of the above-mentioned device, which increases the labor costs.

The present invention provides a soundproof ventilation system that is comprised of two boxes installed on both sides of the glass door or wall, and achieves good soundproofing while reducing manufacturing and installation costs.

Means for Solving the Problems The soundproof ventilation device according to the invention comprises two boxes having the same elongated shape and consisting of ventilation holes in horizontal walls, arranged symmetrically and horizontally with respect to a central horizontal axis; Each of the two boxes is removably fixed and is disposed in place of the glass door or wall, has substantially the same mechanical characteristics as the glass door or wall, and has two circulation holes arranged along a horizontal plane. an intervening stand made of a washable thin film material such as soundproofing foam, which surrounds the intermediate gap between the two circulation holes of the intervening stand, and surrounds the intermediate gap between the two circulation holes of the interposition stand, and the ventilation hole and the circulation hole together with the soundproofing material in each box. It is characterized by comprising a sleeve that forms a flow path connecting the flow path so that the flow path consists only of smooth and uneven wall surfaces.

Since the two boxes are identical, manufacturing costs are significantly reduced. Furthermore, the ventilation channels have good acoustic properties, so that the soundproofing properties are very satisfactory. The device of the invention can be used for both repair and new installations. In the case of repairs, it is possible to cut out parts of the wall and use a stand, but it is also possible to attach the box directly to the wall without additional preparations. In the case of a new installation, only an intervening stand is required. in fact,
The builder will leave enough space on the wall to accommodate the stand or install glass. This allows for standardization of manufacturing while protecting the box and sleeve, which remain in the original packaging until assembly.

Advantageously, the soundproofing material in the sleeve and box is formed such that the flow path has curved walls and has no irregularities. As a result, ventilation does not generate noise. Also, the possibility of pressure build-up within the flow path is prevented.

Also according to the invention, the sleeve is made of a precleanable foamed membrane. Therefore, the ventilation system can be cleaned, and the flow path after cleaning restores its soundproofing performance.

The interposition stand may be at least partially provided with a panel. Particularly when the device of the present invention is attached to a glass door, panels are used in place of the grooves where the mounts cannot be accommodated within the grooves.

In one embodiment of the invention, each box consists of a horizontal profile with a closing wall at each end. The soundproofing material of the box consists of two identical trumpet-shaped members symmetrical about a central horizontal axis. The free faces of the thorn-shaped member are opposite and have openings in the sides opposite the ventilation holes. In this embodiment, the manufacture and installation of the ventilation device of the invention is simplified.

Embodiment As can be seen in particular from FIG.
It consists of two identical boxes: and outer box 2. These 2
The two boxes are provided with ventilation holes 4 and 5 in substantially horizontal wall portions 6 and 7, respectively. The two boxes 1 and 2 are located 180 degrees oppositely to each other about the horizontal axis 8, with the ventilation holes in the inner wall 6 opening upward and the ventilation holes in the outer wall 7 opening downward.

Each of the two boxes 1 and 2 has a wall or a glass door 3
established in It is fixed on an interposition stand 9 installed in the opening. When attaching the ventilation system of the present invention to a glass door, cut out the upper (or lower) part of the glass door into a strip shape, fit the interposed stand 9 into the cut opening, and insert the interposed stand 9 into the groove of the window. Advantageously, it is fixed by. Preferably, a panel 25 (FIGS. 4 and 5) is attached to the surface of the mounting base 9 to strengthen the fixation to the glass door, and the panel is engaged in the groove of the window. The method is also advantageous if the mounting base 9 does not engage directly in the groove of the window. Therefore, the wall or glass door on which the ventilation system of the invention is installed is replaced by an interposed stand. Advantageously, this support is constructed of a material that has the same mechanical properties as the wall or glass door, so as not to reduce the overall mechanical strength of the wall or glass door.

At least one of the ventilation holes 4 or 5 is provided with a filtration device, such as a grid 11 placed on the outside or inside of the box 2. When placed externally, this filtration device prevents the ingress of all types of particles, and when placed internally, it traps fine particles to keep the office clean.

According to the invention, a sleeve 12 is provided which is made of a material that has an acoustically insulating effect. This sleeve is shaped to constitute a flow path connecting the two ventilation holes 4 and 5 together with the soundproofing material in each box. For this reason, the interposition stand 9 has two circulation holes 13 along the horizontal plane at each end of the interposition stand 9.
and 14 are provided. As particularly shown in FIG.
and 14. Preferably, the sleeve 12 has a flow path 1 connecting the ventilation hole and the circulation hole.
6 is shaped to have a smooth surface and no irregularities or corners so that pressure does not increase within the flow path.

Preferably, the soundproofing material used to construct sleeve 12 is a washable foam membrane. This allows the sleeve to be cleaned if necessary. In fact, the soundproofing performance of such foams does not change upon washing.

FIG. 3 is an exploded perspective view of one embodiment of the invention. The box consists of a molded body 17 closed at each end by a closing wall 18. The ventilation hole has an elongated shape and is arranged in the center of the molded body 17.

On the left side of FIG. 3, half of the sleeve is shown exploded. On both sides of the interposer 9, the sound-absorbing material of the channel consists of a tangular member 19 whose bottom 21 is arranged next to the bottom of the shaped body 17. Said thorn-shaped member 1
The free surface 22 of 9 faces toward the interposition base 9 and comes into contact with it when the device is assembled. Part 19
consists of an opening 23 arranged opposite the ventilation hole 4. In the present invention, it is necessary to provide a plate 24 at the bottom of the molded body 17 so as to be interposed between the bottom and the tapered member 19.

As in the box, a member 19 arranged externally and provided within the molded body shown on the right side of FIG.
Although it is not visible in Figure 3, the opening 23 is the ventilation hole 5.
It is arranged with a 180° reversal so that it is placed opposite to.

The ventilation system of the present invention is preferably disassembled, and the boxes 1 and 2 are preferably fixed to the interposition stand 9 in a removable manner. This fixation is possible by interlocking the box with the interposition stand. Alternatively, the box may be fixed by hooking the edge of the box to the intervening stand and fixing the opposing second edge with, for example, screws. Furthermore, the box may be fixed directly to the intervening member by screwing, in which case passage holes are provided at each end of the box for the screws to pass through.

Preferably, the box has good sealing properties at the joints when fixed to the intervening member.

Since the ventilator of the present invention simply consists of two boxes of the same shape, two members of the sleeve of the same shape, and an intervening stand, the manufacturing cost of the ventilator is significantly reduced according to the present invention. The device can be easily disassembled and maintained, especially by cleaning the sleeve.
When dividing, the intervening member remains on the wall or the glass door, and for disassembly all that is required is to remove the box and pull it out from the sleeve member, making the dividing work very easy.

As can be seen in FIG. 1, the inner ventilation hole 4 and the outer ventilation hole 5 are arranged alternately, so that the outer ventilation hole 5 is located in the lower wall of the outer box 2. To prevent moisture from entering and entering the interior of the box through the outer ventilation holes 5, the longitudinal ridges 20 near the ventilation holes protrude from the surface of the box, as shown in FIG. In addition, the internal ventilation holes face upwards, so the cold air that passes through the device is not sent directly to the people in the room. This can occur in ventilation systems where the ventilation holes are arranged vertically.

Advantageously, as shown in particular in FIG. 3, the interposer 9 extends beyond the periphery of the contact surface with the box.
This clearance makes it possible to position the interposer in the groove provided for receiving the glass door or, if necessary, for receiving such a panel. Panels fixed to the base of the structure ensure a tight, tight contact between the base and the glass door or wall. There is also a variant of a stand which has an integral panel on one of the edges suitable for receiving the edge of a glass door as a sealing means.

According to the invention, a flow restrictor, also known as a self-regulating air vent, may also be provided inside the outer box 2 (flow rate of approximately 100 m ³ /h). In that case, the advantage is that the flow rates in the room, which are mechanically ventilated as required, are balanced.

When the device of the present invention is newly installed, it is newly assembled and used, and when it is used to replace an existing device, it can be replaced with the previous device depending on the condition of the stand.

If you do not want to process the wall or window frame, especially if the material is an aluminum molded body or a hollow material that does not interfere with the whole, the ventilation device of the present invention can be installed, for example, in place of the upper part of a glass door. do it. This simplifies the installation work to the utmost.

According to the invention, the ventilation hole presents the interior of a smooth tube and meets standards and specifications for sound insulation.

The use of foam on the membrane surface allows the device to be cleaned, thereby extending its lifespan.
