It is composed with and.

In the present embodiment, the opening O is formed by penetrating the wall W inward and outward by notching the wall W in a horizontally long and substantially rectangular shape as shown in FIG. The opening O is exemplified by a rectangular frame 21 mounted on a door frame 20 surrounding a door opening DO in which a door (not shown) is arranged. Thereby, the opening O is connected to the door opening DO.
Of the door D, as shown in FIG.
This is preferable in that the sense of unity with the ventilation gallery 1 can be enhanced and the appearance can be improved. However, as shown in FIG. 5, the door D and the ventilation gallery 1 can be arranged apart from each other.

As shown in FIGS. 1 and 2, the inner cylindrical portion 2 is made of steel in this embodiment and is formed of a rectangular frame along the inner peripheral surface of the opening O. Weared and fixed. Further, in this example, the inner cylindrical portion 2 is a pair of vertical frame members 2a, 2a.

The upper frame member 2b is provided with a locking piece 5 which can be engaged with the upper part of the one or the other ventilation grill 3 or 4. The locking piece 5 includes a hanging piece 5a that hangs downward, and a bent portion 5b that is bent at a lower end of the hanging piece 5a away from the center plane of the wall thickness and diagonally upward. . In this example, the locking piece 5 is formed of a metal member separate from the upper frame member 2b and is fixed to the upper frame member 2b with a screw or the like, but the upper frame member 2b
The locking piece 5 may be integrally formed.

A mounting piece 6 is provided on the lower frame member 2c. In this embodiment, the mounting piece 6 is configured to extend obliquely upward at a small height in a direction approaching the center plane of the wall thickness. In the present embodiment, the mounting piece 6 is attached to the lower frame material 2.
The lower frame member 2c is formed integrally with the lower frame member 2c by bending both side edges of the lower frame member 2c.
It may be fixed to c.

The ventilation grill 3 (or ventilation grill 4)
As shown in FIGS. 1 and 3, in this example, a rectangular frame portion 7 is provided.
And a grill main body 9 attached to the frame portion 7.

The frame portion 7 is made of, for example, a resin molded product having a decorative finish, and serves to cut off the opening O of the wall W to improve the appearance. The grill body 9
Is a grille frame 9a formed in a substantially rectangular shape, and a plurality of grille blades 9b whose both ends are locked to a vertical member of the grille frame 9a.
It is comprised including.

The grill frame 9a is integrally fixed to the back surface of the frame portion 9a by screws 10. The grill frame 9a has a downwardly projecting protruding piece 11 which can be hooked on and held by the bent portion 5b of the locking piece 5 provided on the inner cylinder portion 2, and a mounting piece 6 provided on the inner cylinder portion 2. A contact piece 12 that is attached to face each other is formed. When attaching such ventilation grills 3 and 4 to the inner cylindrical portion 2, first, the grill main body 9 is fixed to the frame portion 7 using screws 10, and the projections 11 of the grill frame 9 a are bent. 5b. Thereby, the ventilation grills 3, 4
Can be temporarily fixed to the inner cylinder portion 2. Thereafter, the ventilation grills 3 and 4 and the inner cylindrical portion 2 can be easily integrated from the space between the lowermost grill blade 9b and the grill frame 9a using a fixing tool 15 such as a screw or a nail.

In this embodiment, both the other ventilation grilles 3 and 4 have the grill blades 9b inclined so as to descend toward the center of the wall thickness. The ventilation gallery 1 of this example is arranged at a relatively high place on a door. Therefore, by providing the grill blade 9b with such an inclination, the other side of the wall can be hidden from one side through the ventilation gallery 1 to help protect privacy and the like. It is desirable that the angle on the acute angle side of the grill blade 9b with the horizontal plane is, for example, about 20 to 40 °.

Further, the ventilation gallery 1 of the present embodiment is provided with a guide member 13 for guiding the air flowing from one ventilation grill 3 to the other ventilation grill 4 while turning the air flowing in from the one ventilation grill 3 in the inner cylindrical portion 2. I have. In the present embodiment, the guide 13 is
A first guide plate 13A which rises obliquely from the inner surface of the lower frame member 2c of the inner cylinder portion 2 and guides air flowing in from one ventilation grill 3 upward, and an upper frame member of the inner cylinder portion 2 2b, falling obliquely from the inner surface and the first guide plate 13A
And a second guide plate 13 </ b> B that can guide the air guided by the above to the other ventilation grill 4. Another feature is that a sound absorbing material 14 is disposed on the air guide surface A of the first and second guide plates 13A and 13B.

Such a guide 13 blows out the air flowing from one ventilation grill 3 from the other ventilation grill 4 and allows the air to flow in and out of the wall W to perform natural ventilation indoors. Breathability can be improved. Further, the ventilation gallery 1 can blow out the air flowing from one ventilation grill 3 instead of directly blowing it out from the other ventilation grill 4 by changing the direction of the air flow using a guide. At this time, the passing air can be made to contact the sound absorbing material 14 in a wider range, and the sound (air vibration) transmitted together with the air inside the ventilation gallery 1 can be efficiently absorbed. Leakage, entry of sound, and the like can be effectively prevented. Further, in the present embodiment, the ventilation gallery 1 is provided at a high position such as on a door. As a result, it is possible to prevent the ventilation wind from blowing directly to the feet or the like, thereby improving the usability.

The second guide plate 13B has a lower end E1.
Is disposed in the vicinity of the grill blade 9b of the one ventilation grill 3. For this reason, in one ventilation grill 3,
The ventilation space is reduced to a region below the lower end E1 of the second guide 13B. The height of the first guide plate 13A is desirably set to a height that can guide substantially all of the air flowing from the ventilation space along the grill blade 9b. Thereby, the air that flows in efficiently can be received and a sound absorbing effect can be exhibited.

The angle of the first guide plate 13A on the acute angle side with the horizontal plane is desirably, for example, 40 to 70 °, and is approximately 60 ° in this example. The angle of the second guide plate 13B on the acute angle side with the horizontal plane is, for example, 5-8.
Preferably, the angle is 0 °, and in this example, it is approximately 73 ° larger than the first guide plate 13A. In addition, between the upper end of the first guide plate 13A and the second guide plate 13B,
They are separated in the height direction. As a result, sound can be absorbed without excessively decreasing the ventilation volume.

As the sound absorbing material 14, any material can be used as long as sound energy can be converted into heat energy and consumed when passing or colliding, such as cotton, woven fabric, nonwoven fabric, foam, and porous material. Various materials such as glass wool and felt can be used. In the present embodiment, each of the guide plates 1 is formed by molding acrylic cotton into a sheet.
3A and 13B illustrate examples attached to the air guide surface A. Further, in the present embodiment, an example in which the sound absorbing material 14 is arranged over the entire area of the air guide surface A of the guide 13 is described.
Without being limited to such an aspect, it is also possible to partially dispose.

Although the ventilation gallery of this embodiment turns air up and down, for example, a guide that can turn air left and right can be used instead. In addition, as shown in FIG. 6, when a house is provided with a forced fan 30 that can introduce, for example, outside air (underfloor air) into a house, the indoor ventilation efficiency can be further improved.

[0025]

As described above, according to the first aspect of the present invention, a guide is provided for guiding the air flowing from one ventilation grill to the other ventilation grill while turning the air, and the guide for the guide is provided. Sound absorbing material is arranged on the air guide surface. This allows the air to touch the sound absorbing material over a wider area without lowering the ventilation volume, effectively absorbing the sound inside the ventilation gallery, effectively preventing sound leakage, sound entry, etc. Can be prevented.

As described in the second aspect of the present invention, the ventilation gusset is particularly useful for protecting privacy when the opening is provided at a high position such as an opening above a door provided on a wall. In addition, as a result of being able to provide ventilation at high altitudes, it is possible to prevent ventilation wind from blowing directly to the feet, etc., and to enhance usability.
