The present invention relates to an elevator door assembly of an elevator system, and more particularly to an elevator door assembly having a deformation preventing structure for preventing deformation of the door panel and the operator frame of the elevator door assembly.

The landing door assembly is attached to the wall forming the hoistway, and includes an operator panel having a hanger rail, one or more landing doors supported by the operator frame via a hanger plate movably supported on the hanger rail, and the landing below the operator frame. A pair of jam poles formed at both sides of the entrance hole, and a seal formed at the lower side of the entrance opening and receiving the lower end of the entrance door to guide the movement thereof.

The operator frame is made of a thin plate of the main body, and the boarding door is usually composed of a door panel formed by plate processing of a plate-shaped material. Such plate and plate processing parts have the advantage of being able to cover a large area while reducing the parts consumption, but has the disadvantage of being easily deformed by external forces such as impact.

When deformation occurs in the door panel due to external impact, etc., it should be avoided that the gap between the door panel and the jam pole is excessively extended beyond a predetermined size gap (typically 5 mm) held between the door panel and the jam pole. Large gaps between the door panels and jam poles can pose great risks for passengers on board, especially children. In addition, if the deformation is severe and the door panel is separated from the seal member, the door panel may fall into the hoistway.

On the other hand, in the case of an operator frame which is usually supported by anchors on both the left and right sides, deflection deformation tends to occur downward due to the weight of the door panel and the like.

In order to prevent deformation of the sheet and the parts by the processing of the sheet, a generally known method is to use a reinforcement to increase the rigidity of the part.
