Title:
ELEVATOR LANDING DOOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/125372
Kind Code:
A1
Abstract:
The present invention provides an elevator landing door device that includes a landing door that does not readily thermally deform and that can ensure sufficient fire-resistance performance with a low-cost structure. In this elevator landing door device, an overlapping joint of landing doors (1L, 1R) is configured from door covers (2L, 2R), and the overlapping joint door covers (2L, 2R) have a closed cross-sectional shape. As a result, the overlapping joint structure is unlikely to collapse due to thermal deformation and the door is unlikely to deform in a snaking shape in the door longitudinal direction.
