ABSTRACT:
The elevator landing door apparatus is provided with a door for opening and closing the doorway at an elevator landing zone, a rail for guiding the rollers of a hanger plate installed in an upright position in the upper part of the door just defined, and a sill for guiding a door shoe set in the lower part of the door laid out in the lower part of the doorway defined above. The elevator landing door apparatus is characterized in that a plate is set up in an upright position on the upper frame of three-side frames in the doorway defined above and a closure plate is set up in the upper part of the door defined above and forms an overlapping construction together with the plate when the door is shut. This closure plate is fitted out with an expansive material which expands by the effect of heat and thereby the clearance between the plate and the closure plate.
