DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gull for a vent.

[0002]

2. Description of the Related Art In a ventilation hole provided in a building such as a building or a house, a damper-like material called a gull is usually attached to a ventilation hole opening in a wall surface.

[0006] As shown in FIGS. 6 to 8, a conventional rattle is formed by pressing or extruding a tubular vent insertion portion 1, a vane portion 2, and a hood portion 3 from a plate material such as aluminum. These are superposed by interposing a wire mesh 5 between the flange portion 4 and the vane portion 2 of the ventilation hole insertion portion 1 and integrated by rivets 6, spot welding or the like.

[0004] Reference numeral 7 denotes a stopper fitting which is attached to the outer peripheral portion of the vent insertion portion 1 at several places (three to four places) in the circumferential direction.
Is an opening formed in the hood 3.

[0005] According to such a structure, the ventilation hole insertion portion 1 is pushed into the ventilation hole portion of the building until the flange portion 4 comes into contact with the wall surface, and is fixed to the ventilation hole portion with the retaining metal fitting 7, whereby the hood portion 3 is formed. In a state where the vent portion is protected by this, ventilation is performed between the inside and outside of the building through the opening 8 of the hood portion 3, the vane portion 2, the wire mesh 5, and the vent insertion portion 1.

In addition, the vane 2 and the wire mesh 5 prevent insects and the like from entering the interior of the building.

[0007]

[0007] However, the above-mentioned conventional louver for vents has the following problems.

More specifically, a tubular vent insertion portion 1 and a vane portion 2 are formed from a plate material such as aluminum by pressing or extrusion.
And the hood portion 3 are formed, but in this case, the processing cost by press or extrusion is high, and it is difficult to consolidate parts due to restrictions. In addition, strength and dimensional accuracy cannot be so high.

Further, since the flange portion 4, the wire netting 5, the vane portion 2, and the hood portion 3 of the ventilation hole insertion portion 1 are overlapped and integrated by rivets 6, spot welding, or the like.
It takes time and effort to assemble.

Further, since the vane portion 2 has a shape which does not resist the invasion of air or the like from the outside,
When the wind is strong, the wind or the like may enter the inside vigorously to generate noise such as an inflow sound or a reverberation sound.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a ventilation louver which is inexpensive and capable of preventing generation of noise due to air flow.

[0012]

SUMMARY OF THE INVENTION The present invention includes an inlet vent portion 13 insertable tubular vent insertion portion 14 into the vent hole 12 formed in the wall 11 of the building 10, the vent
A contact lockable flange portion 15 to the wall 11 of the building 10 is disposed to the front end outer periphery of the mouth insertion portion 14, the vent
Arranged so as to close the side of the mouth insertion portion 14 where the flange portion 15 is formed
15A, and a lid protruding forward from the lid 15A.
Vent hole 1 that communicates with the outside of the vent insertion portion 14
A casting gallery body 18 integrally formed with a large number of ventilation cylinders 17 each having a 6 is provided, and a casting hood portion 24 capable of surrounding the ventilation cylinder 17 is attached to the gallery body 18. It is related to the dust for ventilation.

According to the above means, the following effects can be obtained.

The ventilation hole insertion portion 14 is pushed into the ventilation hole portion 13 of the building 10 until the flange portion 15 abuts on the wall surface 11, and the ventilation hole portion 13 is protected by the hood portion 24. Ventilation is performed between the inside and outside of the building 10 through the ventilation hole 22 of the hood opening 21, the ventilation tube 17 of the flange portion 15, and the ventilation hole insertion portion 14.

The double ventilation holes 22 and 16 prevent insects and the like from entering the interior of the building 10.

In the present invention, the casting loudspeaker body 18 integrally having the ventilation port insertion portion 14, the flange portion 15, and the ventilation tube 17 and the casting hood portion 24 having the ventilation holes 22 form the casting louver. The configuration makes it possible to consolidate parts and reduce costs as compared with a case where a plate material such as aluminum is pressed or extruded. Moreover, since it is a cast, it has high strength and durability, has good dimensional accuracy, and is easy to assemble.

Further, the ventilation cylinder 17 is provided with a resistance to the intrusion of air or the like from the outside to weaken the flow velocity,
Since the air or the like is caused to flow from the inside, the wind or the like does not enter the inside vigorously in a strong wind, so that noise such as an inflow sound and a reverberation sound can be prevented.

Also, in the event of a fire or the like, the ventilation tube 17 prevents the flame from entering the interior.

[0019]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 5 show an embodiment of the present invention.
