Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a soundproof ventilation fitting suitable for use in doors, sliding doors and the like.

[0002]

2. Description of the Related Art Conventionally, for natural ventilation of a building, it has been known to provide a ventilation opening as shown in FIG. That is, a panel b forming a door, a wall surface, or the like is provided with a gallery b, a mesh plate c therein, and an opening / closing plate d consisting of a pair of slide plates on the inside. The ventilation port v is opened and closed by a vertical (or left-right) sliding operation.

However, it is often experienced that the ventilation port having such a structure has almost no soundproof performance and that the effect is not so great even when the opening / closing plate d is closed. Therefore, technology has been developed in which a soundproof function is added to the ventilation port. For example, Shokai 62
Japanese Patent Laid-Open No. 73092 and Japanese Patent Laid-Open No. 5-302369 disclose a soundproof ventilation device in which a sound absorbing material is attached to the inner surface to impart soundproof performance.

However, in the above-mentioned prior art, it is necessary to lengthen the passage in order to provide sufficient sound absorbing performance,
Since a partition wall is provided inside the device to form a labyrinth or a passage for bending the sound absorbing material to project is provided, there is a problem that the air flow is obstructed and the ventilation effect is impaired. Further, it not only takes a lot of time and labor to attach a specific device to a door, but also a space for the door or a wall surface is required.

[0005]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, and provides sufficient ventilation and soundproofing by simply devising a simple structure for doors and fittings. An object is to provide a soundproof ventilation fitting.

[0006]

The soundproof ventilation fitting according to the first aspect of the present invention is such that a space between the peripheral edges of two plate-like members disposed opposite to each other is closed by a crosspiece to form a hollow inside. A sound absorbing material is provided on the inner surface of the made panel, and ventilation holes are provided at the upper part of one plate and the lower part of the other plate, respectively.

The soundproof ventilation fitting according to a second aspect of the present invention is a panel in which a space between two peripheral edges of two plate-like members arranged opposite to each other is closed by a crosspiece to form a hollow inside. , A sound absorbing material is provided on the inner surface, and ventilation openings are provided along one side edge on one lateral edge of one plate body and on the other lateral edge of the other plate body in the lateral direction. It is what

Generally, there are roughly two types of natural ventilation. One is a ventilation method based on the temperature difference between the inside and outside of the room.It is known that it is effective to provide ventilation openings on one wall and the other wall facing it, and separate the positions of each ventilation opening vertically. ing. In other words, buoyancy is generated in warm air in the room, heavy cold air is sucked in from the lower ventilation port, and light warm air is discharged from the upper ventilation port. The invention according to claim 1 adopts this principle to a fitting.

The other one is a ventilation method using wind power, and it is known that it is effective to provide ventilation ports on the outer wall facing the windward side of the building and the outer wall facing the leeward side facing the outer wall. Has been. In other words, air is circulated by the pressure difference between the inside and the outside of the wall surface. The invention according to claim 2 adopts this principle to a fitting.

The sound absorbing material used in the present invention is not particularly limited, but it exhibits sound absorbing performance due to friction loss with air, such as glass wool, rock wool, felt, and foamed plastic having open cells. Porous material for relatively high frequencies, such as plywood, hardboard, etc.
A plate material for a relatively low sound range that exhibits sound absorbing performance by resonance can be used.

The above-mentioned sound absorbing material is attached to the inner surface of the plate-like body constituting the panel by means of sticking with an adhesive or the like, but it is not always necessary to attach it to the entire surface, and it may be a part thereof. In any case, even if the same sound absorbing material is used, the sound absorbing coefficient tends to be significantly different depending on the usage. Therefore,
Considering the types of fittings, installation locations, types of sound generation, panel structure and materials, and other factors, a combination of multiple types of sound absorbing materials is used. Is preferred.

When a slit-like ventilation hole is provided as in the embodiment described later, it has a resonance absorbing effect with the air inside the cavity of the panel, which is superior to the case where only the sound absorbing material is used. Sound absorption effect may be obtained.

The soundproof and ventilation fittings of the present invention include not only doors and sliding doors that serve as indoor and outdoor partitions, but also all movable partition walls in the room and the like that fall into the category of fittings. It should be noted that it is optional to use a conventionally used technique, for example, the above-mentioned louver or mesh plate, together with the ventilation port in the present invention.

(Operation) In the soundproof ventilation fitting according to the invention as defined in claim 1, two plate-like members are arranged so as to face each other, and a space between the peripheral edges of each plate-like member is closed by a crosspiece so that the inside is hollow. Since a panel having such a structure is used, and ventilation holes are provided in the upper part of one plate and the lower part of the other plate, respectively, a vertical large-capacity ventilation path is formed in the fitting. Further, since the sound absorbing material is provided on the inner surface of the panel, the sound absorbing effect is given to the sound generated inside and outside the fitting without being greatly affected by ventilation. Therefore, when it is mainly used as a ventilation means that utilizes the temperature difference between the inside and the outside, it exhibits a ventilation / sound absorbing effect.

In the soundproof ventilation fitting according to the second aspect of the present invention, two plate-shaped members are arranged so as to face each other, and the inside of each plate-shaped member is closed by a crosspiece to form a cavity. Since the panel is used and the ventilation openings along the side edges are provided at the one lateral edge of one plate and the other lateral edge of the other plate, respectively A large capacity air passage is formed. Also, because a sound absorbing material is provided on the inner surface of this panel,
The air is not significantly affected by the ventilation, and the sound generated inside and outside the fitting is also absorbed. Therefore, when used as a ventilation means mainly utilizing wind power, it exerts a ventilation / sound absorbing effect.
