Abstract: Elevator landing door structure, comprising a door sill (1, 5) fixed to the lower edge of a landing door opening, an overhead supporter (2, 9) and at least one door panel (3) movably mounted on the overhead supporter. Furthermore, the door structure comprises vertical frames (4, 6) fixed to the door sill (1, 5) on either side of the door opening, the overhead supporter being attached to said vertical frames. The vertical frames (4, 6) are fastened by their upper parts via junctures that are rigid in the horizontal plane but capable of yielding in the vertical direction.
