Title:
DOOR DEVICE FOR ELEVATOR
Document Type and Number:
WIPO Patent Application WO/2019/058413
Kind Code:
A1
Abstract:
This door device for an elevator is provided to a lower section of a single swing door. A door slip-out prevention member that comes in under a doorstop-side frame against which the door abuts is provided to a door shoe fitted into a threshold groove of a threshold. An accommodation section for accommodating the door slip-out prevention member when the door has closed a doorway is provided below the doorstop-side frame. Because the door slip-out prevention member comes into the accommodation section under the doorstop-side frame when the door has closed the doorway, door slip-out, where the door shoe separates from the threshold groove, is prevented since, even if an external force is applied in a direction perpendicular to the direction of opening and closing of the door and the door bends, which might cause the door shoe to move upward, the door slip-out prevention member abuts against under the doorstop-side frame, which is above the accommodation section, thus restricting upward movement of the door shoe.
