Problems solved by technology

On the other hand, if the gap above the specified value is not ensured, the door may come into contact with its periphery when opening and closing the door, which may cause abnormal noise or equipment failure.
Therefore, since it is necessary to strictly adjust the size of the gap, when the number of installations or the number of floors is large, there is a problem that the adjustment takes a long time depending on the operator's proficiency.

Abstract

An elevator door device (9) is provided with a door (21) disposed so as to be slidable in the opening and closing direction, and a threshold (25) having a groove (23) for guiding a lower part of the door in the opening and closing direction. The door includes a door panel (27) and a door shoe (29) disposed at the bottom edge of the door panel. The door shoe is provided with at least one support hole part (51) through which pass a load support member for supporting the load of the door and a fixing member for fixing the door shoe to the door panel. The support hole part is configured so that the load support member and the fixing member are disposed at different heights with respect to the door shoe.

Description

technical field [0001] The invention relates to an elevator door device and an elevator door installation method. Background technique [0002] An elevator includes a shaft extending up and down and a car installed so as to be movable in the shaft. At least one car door is provided at the front portion of the car, and the car door is used to open and close the car entrance and exit for passengers to enter and exit. In addition, a landing doorway is provided in a plurality of target floors of a structure having a hoistway so as to be able to face the car doorway. At least one landing door is arranged in each of the landing entrances and exits. [0003] The gaps between these doors and the peripheral parts of the doors are regulated so as to be less than or equal to a predetermined value. On the other hand, if the clearance above the specified value is not ensured, the door may come into contact with its peripheral portion when the door is opened and closed, which may cause...
