Document Type and Number:
Japanese Patent JP7211823
Kind Code:
B2
Abstract:
To connect neighboring door bodies while preventing thrust load from applying to a door body due to generation of a standing angular difference between neighboring door bodies.SOLUTION: A roof gate 1 comprises: a plurality of door bodies 10 provided side by side in a width direction and standing by rotating around a rotating axis 11 at a base end side by buoyance to stand from a fallen state; and a connection portion 40 connecting the neighboring door bodies 10 with each other. In the connection portion 40, one end is connected to one door body 10 side of ones adjacent to each other, and the other end includes a rope-like member 50 connected to the other door body 10 side. When the rope-like member 50 is tensioned by standing angular difference between the neighboring door bodies 10, an angle between an extending direction of the rope-like member 50 and a width direction of the door body 10 is a right angle.SELECTED DRAWING: Figure 10
