Title:
DOOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/109833
Kind Code:
A1
Abstract:
A door device (40) has engagement members (104, 106) for operating a lock mechanism (101) of a landing door (100a) and has a pair of engagement vanes (22, 27) opening and closing each other, clamping the engagement members (104, 106) in their closed state to hold the lock mechanism (101) in a deactivated state. The engagement vanes (22, 27) are held closed by cam mechanisms (29, 30) and a holding mechanism (33). Even when the landing door (100a) moves in a door closing direction to release the engagement members (104, 106) from the holding maintained by contact between the members and the cam mechanisms (29, 30), the engagement vanes (22, 27) are held closed by the holding mechanism (33). Reaction force occurring when the landing door (100a) reaches and stops at a door stop position moves both engagement vanes (22, 27) in a door opening direction, and by which the lock mechanism (101) is activated.
