Document Type and Number:
Japanese Patent JP7209737
Kind Code:
B2
Abstract:
Provided is an elevator landing-side door device with which it is possible to suppress the formation of a gap between the lower end surface of a landing-side door and a sill and suppress the entry of flame and smoke to the hoistway side. A door shoe bracket 11 having a length dimension that is equivalent to the overall width of a door panel in the horizontal direction and having a designated strength is attached to the lower end of the door panel 9 on the side thereof facing the hoistway, the door panel 9 being disposed so as to face a sill 13 including a guide groove 18. The lower end side of the door shoe bracket 11 extends so as to be located inside the guide groove of the sill. Since the long door shoe bracket 11 having the designated strength is provided, deformation on the lower-end side of the door panel 9 is suppressed and no gap is formed, and thus it is possible to suppress the entry of flame and smoke into the hoistway. Furthermore, since the lower-end side of the door shoe bracket 11 is located inside the guide groove 18 of the sill, it is possible to suppress the entry of flame and smoke into the hoistway from between the sill 13 and the door panel 9.
