Document Type and Number:
Japanese Patent JP6856487
Kind Code:
B2
Abstract:
To sufficiently suppress displacement (flexure) generated by a lifting force in a door body in a falling-down state.SOLUTION: A lifting gate 1 comprises: a door body 10 rotating and standing by buoyance of infiltrating water; an auxiliary driving portion 20 constantly applying a lifting force for supporting a standing operation of the door body 10 to both end portions in a width direction of the door body 10 in a falling-down state; two rod members 31a, 31b generating a bending moment acting against a bending moment generated by application of the lifting force by applying an axial force in the width direction to the door body 10 in the door body 10 in the falling-down state; and a turn buckle 33 capable of changing magnitude of the axial force.SELECTED DRAWING: Figure 5
