Description

[Detailed description of the device] [Industrial applications]

 The present invention relates to a ventilation structure for a building such as a house.

[Prior art]

In the past, ventilation holes were provided on the end wall of a house by means of a flat plate horizontally installed. Further, in recent years, a ventilation gallery disclosed in Japanese Utility Model Laid-Open No. Sho 62-193091 is known. This publicly known Shokai
The technique of Japanese Laid-Open Patent Publication No. 62-193091 is such that a large number of fixed louvers each having a bowl-shaped groove at one end are attached and fixed to a gallery frame at a predetermined interval, and can be rotatably inserted into the groove. A movable louver having a rod is rotatably attached to the fixed louver, and a weight for rotation adjustment is attached to the movable louver to keep the center of rotation at a predetermined position.

[Problems to be solved by the device]

According to the above-mentioned known technique, the fixed louver has a complicated structure with the movable louver, and in particular, a separate weight for adjusting the rotation is attached to the lower and other side part of the movable louver, and when the wind pressure is weakened, the action of the weight is reduced. The movable louver rotates to restore the original state to form a gap, which has a drawback that the entire structure is complicated and the weight is heavy.

[Means for solving the problem]

Between the side plates forming the frame body 2, a plurality of rising plates 5 each having a support shaft 6 are attached at intervals in the vertical direction, and the lower end of the lock plate 4 is pivotally attached to the support shaft 6 to stand upright. The contact plate 3 that comes into contact when the wind pressure 4 rotates due to wind pressure is attached to a position located outside and above the support shaft 6 provided on the rising plate 5, and when the wind pressure is released, the lock plate 4 is moved by its own weight. The present invention provides a ventilation port for a building, characterized in that a stopper 7 that locks in an inclined state at an appropriate interval is attached to a side plate located above the rising plate 5.

[Action]

Since the lock plate is pivotally attached to the lower part of the frame body, on a day of snowstorm or a day of strong wind, the lock plate is brought into contact with the contact plate at the inner upper part by wind pressure to be cut off from the outside. When the strong wind stops, the lock plate falls outward from the contact plate by its own weight, is released, and is locked by the stopper. On weekdays, pleasant ventilation is provided from the opening above the lock plate.

【Example】

FIG. 1 is a side view in which the present invention is implemented and a part of which is omitted. A frame 2 that forms a ventilation port is attached to the bundle column 1 that is the end wall of the house and the outer wall 10. In this embodiment, a three-column set is shown, and the ventilation port has a bottom plate 9 and an upper contact plate 3.
Consists of Bearings 11 are provided on both sides of the lower part, and a support shaft 6 provided under the lock plate 4 is inserted to be rotatable. The contact plate 3 is formed slightly outside the bearing 11, and the weight of the lock plate 4 itself is located outside. Therefore, when the wind pressure is released, the lock plate 4 automatically falls and locks on the stopper 7 due to its weight. The bottom plate 9 is inclined to the outside to some extent, and rainwater runs off by the bottom plate and the outside of the lock plate 4 in the case of wind and rain. Reference numeral 8 is a conventional general glazing plate, and a plurality of them are arranged vertically. If necessary, the design of the exterior is adjusted by using round bars of the lattice.

【effect】

Since it is configured as described above, by using natural wind without using any special equipment, it blocks the outside during wind and rain and snowstorms, and provides sufficient ventilation in daily life, providing a comfortable residence for all four seasons. Have an effect.
