WIPO Patent Application WO/2012/176297
Kind Code:
A1
Abstract:
An elevator landing door device, wherein a door-side door-pocket-blocking section is provided to the end of a landing door body on the door pocket side thereof. On each vertical frame of a three-sided frame of a landing, there is provided a vertical-frame-blocking section, the door-side door-pocket-blocking section coming into contact with the vertical-frame-blocking section when the landing door body is fully closed. A door pocket airtight member made from an elastic body is provided to the door-side door-pocket-blocking section and/or the vertical-frame-blocking section. The surface of contact between the door-side door-pocket-blocking section and the vertical-frame-blocking section is inclined, relative to the direction in which the landing door body opens and closes, in a direction in which the door-side door-pocket-blocking section is caused to elastically deform by a force that is caused to act on the landing door body by the difference in air pressure between the landing and a hoistway.
