To provide a lift-up type shelter door enabling easy movement between an aboveground and underground shelter with simple equipment.SOLUTION: A lift-up type shelter door 1 comprises a door body 10 that opens and closes an opening 110 provided in a ceiling 101 of a shelter 100, a lift platform 20 that is connected to the door body 10 via a support 12 in a state in which a predetermined distance from the door body 10 can be maintained, a pantograph-type link mechanism 30 that has one end slidably connected to the lift platform 20 and the other end slidably connected to a floor 102 of the shelter 100, a displacement restraint rail 50 that extends along a lifting direction D1, a pivot shaft 60 that pivots and supports the intermediate intersection where the link members that are constituent members of the link mechanism 30 intersect at their intermediate portions and is slidably connected to the displacement restraint rail 50, and a drive mechanism 40 that drives the link mechanism 30. When the drive mechanism 40 is operated to drive the link mechanism 30, the pivot shaft 60, the lift platform 20, and the door body 10 are displaced synchronously along the lifting direction D1.SELECTED DRAWING: Figure 1

    【課題】簡単な設備で容易に地上と地下シェルター間を往来できるリフトアップ式シェルター扉を提供する。【解決手段】リフトアップ式シェルター扉1は、シェルター100の天井101に設けられる開口部110を開閉する扉本体10と、支柱12を介して扉本体10と所定間隔を維持できる状態で扉本体10に接続する昇降台20と、一端が昇降台20に、他端がシェルター100の床102にスライド可能に接続するパンタグラフ式のリンク機構30と、昇降方向D1に沿って延びる変位拘束レール50と、リンク機構30の構成部材となるリンク部材同士が中間部で交差する中間交差部を軸支するとともに変位拘束レール50にスライド可能に接続する軸支軸60と、リンク機構30を駆動する駆動機構40を備えている。駆動機構40を動作してリンク機構30を駆動させたとき、軸支軸60、昇降台20、および扉本体10は同期して、昇降方向D1に沿って変位する。【選択図】 図1
