WATER IMMERSION PREVENTIVE DEVICE FOR VENTILATION HOLE
PROBLEM TO BE SOLVED: To provide a water immersion preventive device for a ventilation hole that can be adapted for a large-sized formation of the ventilation hole by enabling a plurality of cap members to be opened or closed under a well-balanced state through one driving source.SOLUTION: A frame member 21 is installed within a longitudinal ventilation port 12, a driving unit fixing member 22 is fixed at the central part of the frame member 21 and suspended down and then a lifting drive unit 23 is supported by the driving unit fixing member 22. A link fixing member 24 is driven to lift by the lifting drive unit 23 and several links 25 are connected symmetrically through a shaft to the link fixing member 24 while holding the link fixing member 24. Each of several cap members 28 is pivotally supported on the central part of the frame member 21 and each of these cap members 28 is opened or closed by the several links 25.
【課題】１つの駆動源で複数の蓋部材をバランスよく開閉できるようにすることで、換気口の大型化に対応できる換気口の浸水防止装置を提供する。【解決手段】縦方向の換気口12内に枠部材21を設置し、この枠部材21の中央部に駆動部取付部材22を取り付けて垂下させ、この駆動部取付部材22により昇降駆動ユニット23を支持する。昇降駆動ユニット23によりリンク取付部材24を昇降駆動するようにし、このリンク取付部材24にこのリンク取付部材24を挟んで対称状に複数のリンク25を軸連結する。上記枠部材21の中央部上に複数の蓋部材28をそれぞれ軸支し、これらの蓋部材28を複数のリンク25によりそれぞれ開閉する。【選択図】図１
