WATERPROOF PLATE DEVICE

To provide a waterproof plate device allowing a receiving part 2 to be opened through erection of a waterproof plate 3 to be automatically covered in the case of erecting the waterproof plate 3 received in the receiving part 2 in a floor surface part to prevent water intrusion in order to prevent water intrusion from an entrance opening to an indoor due to inner water flooding upon an emergency situation such as heavy rain.SOLUTION: A waterproof plate device is configured to connect a lid body 7 formed in a nest joint shape to a waterproof plate 3 with wire 9 so as to cover a receiving part 2 to be opened through movement of the lid body together with its extension interlocking with erection and oscillation to a waterproof attitude from a storage attitude after the waterproof plate 3 receives energized force of a dumper member 5.SELECTED DRAWING: Figure 4 【課題】大雨等の非常事態により内水氾濫等になって水が出入り口部から室内に浸入するのを防止するため、床面部の収納部２に収納していた防水板３を起立させて防水する場合に、防水板３が起立したことにより開口する収納部２を自動的に覆蓋するようにする。【解決手段】入子継手状に構成される蓋体７を防水板３にワイヤ９を介して連結し、防水板３がダンパ部材５の付勢力を受けて収納姿勢から防水姿勢に起立揺動することに連動して蓋体が伸長しながら移動することにより開口した収納部２を覆蓋するようにする。【選択図】図４
