DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilating frame for a building, which is attached to a ventilating wall of a building.

[0002]

2. Description of the Related Art Conventionally, various types of ventilators for attics of buildings have been proposed, and among them, in general, a ventilating hole provided on the side of the wife's side of the building communicates with the inside and outside. In addition, there has been proposed a ventilator including a ventilation port frame having an inclined louver that rises from the outside to the inside, and a cover body that covers the ventilation port frame and is partially open.

[0003]

However, such a ventilator can prevent the intrusion of rainwater or the like in the case of normal rainfall, but can prevent the intrusion of rainwater in the case of strong wind. It was not enough for intrusion.

That is, in the conventional ventilation device, since the louver is formed so as to rise from the outside to the inside, in the case of a rainfall accompanied by a strong wind, the external airflow hitting the louver blows up along the louver. . As a result, there is a problem that rainwater easily passes between the louvers and enters the attic.

Accordingly, the present invention has been made in view of the problems existing in such prior art, and an object of the present invention is to provide a ventilation frame for a building which has excellent ventilation capacity and does not allow rainwater or the like to enter. It is to provide.
