As a result, a floor seal member made of a viscoelastic plate material is provided which is displaced to a waterproof position for preventing the inflow of water from the landing to the hoistway by raising the threshold side.

As a result, rainwater or the like at the landing flows down from the sill, accumulates in the water receiving container and accumulates, and the increase in the amount of water in the water receiving container causes the dam plate to be displaced to the waterproof position via the response mechanism. The displaced weir plate raises the sill side of the floor sealing material, thereby preventing water from flowing from the landing to the hoistway. Therefore, rainwater, etc. flows from the landing to the hoistway, floods the pits and impairs the functions of the equipment in the pits, making the elevator inoperable for a long time to recover from flood damage, For this reason, there is an effect of preventing the occurrence of a problem that a large amount of cost is required.

Further, as described above, the present invention is provided with the detection switch which operates when the waterproof position of any of the weir plate and the floor surface sealing material is changed in accordance with the inflow of water from the landing floor to the hoistway. Things.

As a result, rainwater or the like at the landing flows down from the sill, accumulates in the water receiving container and accumulates, and the weir plate is displaced to the waterproof position via the response mechanism due to the increase in the amount of water in the water receiving container. And the inflow of water from the landing to the hoistway can be prevented by the displaced weir plate. Therefore, rainwater, etc. flows from the landing to the hoistway, floods the pits and impairs the functions of the equipment in the pits, making the elevator inoperable for a long time to recover from flood damage, For this reason, there is an effect of preventing the occurrence of a problem that a large amount of cost is required. In addition, the operation of the detection switch at the time of displacement of the waterproof position of any one of the weir plate and the floor surface sealing material has an effect of enabling abnormal control such as stopping the operation of the elevator.

Further, as described above, the present invention is provided on the side edge of the entrance / exit frame of the hall and is always disposed at the retired position in an upright posture, and is disposed on the floor side of the hall via the operation of the response mechanism. A weir plate is provided which is displaced to a horizontal position in contact with and displaced to a waterproof position for preventing water from flowing from the floor to the hoistway.

As a result, rainwater or the like at the landing flows down from the sill, accumulates in the water receiving container and accumulates, and the waterproof plate is brought into contact with the floor side of the landing from an upright posture via a response mechanism due to an increase in the amount of water in the water receiving container. Displace to position. And the inflow of water from the landing to the hoistway can be prevented by the displaced weir plate. Therefore, rainwater, etc. flows from the landing to the hoistway, floods the pits and impairs the functions of the equipment in the pits, making the elevator inoperable for a long time to recover from flood damage, For this reason, there is an effect of preventing the occurrence of a problem that a large amount of cost is required.

Further, as described above, the present invention is provided at the side edge of the entrance / exit frame of the landing and is normally contracted and arranged at the retreat position, and is inflated through the operation of the response mechanism. And a dam plate which is displaced to a waterproof position in contact with the floor side of the landing to prevent water from flowing from the floor to the hoistway.

As a result, rainwater or the like at the landing flows down from the sill, accumulates in the water receiving container, and accumulates. The increased amount of water in the water receiving container causes the dam plate to expand from the contracted retreat position via the responsive mechanism, thereby increasing the landing. Displaced to a waterproof position where it touches the floor side and prevents water from flowing from the floor to the hoistway. And the inflow of water from the landing to the hoistway can be prevented by the displaced weir plate. Therefore, rainwater, etc. flows from the landing to the hoistway, floods the pits and impairs the functions of the equipment in the pits, making the elevator inoperable for a long time to recover from flood damage, For this reason, there is an effect of preventing the occurrence of a problem that a large amount of cost is required.

Further, as described above, the present invention is provided in the recess near the entrance of the landing floor and is always arranged at the retreated position in which it falls down, and is driven by the drive mechanism via the operation of the response mechanism to stand up. A weir plate that is displaced to a waterproof position that prevents water from flowing from the landing floor to the hoistway, and air that is provided on both side edges and a lower edge portion of the weir plate when standing and constantly contracts and expands when standing up And a bag.

As a result, rainwater or the like at the landing flows down from the sill, accumulates in the water receiving container and accumulates, and is driven by the driving mechanism via the response mechanism by the increase in the amount of water in the water receiving container, whereby the weir plate rises and rises. It is displaced to a waterproof position to prevent water from flowing from the floor to the hoistway. And the inflow of water from the landing to the hoistway can be prevented by the displaced weir plate and the inflated airbag. Therefore, rainwater, etc. flows from the landing to the hoistway, floods the pits and impairs the functions of the equipment in the pits, making the elevator inoperable for a long time to recover from flood damage, For this reason, there is an effect of preventing the occurrence of a problem that a large amount of cost is required.
