Abstract (en)
[origin: EP1418150A1] An elevator landing door has a reinforcement member (2) provided on a back of a door panel (1) for enhancing rigidity. The elevator landing door has an adhesive (3) for bonding the door panel (1) and the reinforcement member (2) together and a thermally-expanding agent (4) interposed between the door panel (1) and the reinforcement member (2). Upon exposure to intense heat stemming from occurrence of fire or the like, the thermally-expanding agent (4) inflates, thereby separating the door panel (1) from the reinforcement member (2). Hence, there can be prevented deformation of the door panel (1), which would otherwise be caused by a difference between the door panel (1) and the reinforcement member (2) in terms of coefficient of thermal expansion. As a result, the entrance of the elevator can be sealed by the door panel (1) without fail, thereby preventing intrusion of smoke and flame into a car compartment or a hoistway. <IMAGE>
