Title:
OPENING/CLOSING DRIVING MECHANISM OF SMOKE-SHIELDING SLIDING DOOR DEVICE
Document Type and Number:
Japanese Patent JP3968655
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an opening/closing driving mechanism of a smoke-shielding sliding door device which enables the opening of only one sliding door without the synchronization of right and left smoke-shielding sliding doors brought into a closed state in the case of fire, and prevents the relocking of a release unit and a holding member for keeping the sliding door in an opened state, in this case.
SOLUTION: A wire member 27 is connected to the holding member 41 which can be engaged with/disengaged from the release unit 44. An upper transfer part 38 of the wire member 27 is provided with a locking member 40 corresponding to one sliding door 4, and a lower transfer part 39 is provided with a locking member 40 corresponding to the other sliding door 5. Both the sliding doors 4 and 5 can be relatively moved with respect to the corresponding locking members 40, and abut on each other by virtue of an urging force in a closing direction. Since one sliding door 4 is relatively moved with respect to the locking member 40 without the go-around of the wire member 27 when brought into the opened state from the closed state, the other sliding door 5 and the holding member 41 are not brought into moving states from closed states.
