Title:
DOOR LOCK DEVICE FOR DOOR-EQUIPPED PARTITION
Document Type and Number:
Japanese Patent JP3243205
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To facilitate the control of a partition by automating a door lock device provided on a movable panel and to enhance the locking function of the automated door lock device.
SOLUTION: The locking and unlocking of a door 9 by the lock member 15 of a movable panel 3 are automatically effected by an electric motor 16. While the movable panel 3 is moving, the door 9 is not opened inadvertently as it is locked by the lock member 15 of the movable panel 3 even if a lock member 19 in the door 9 is unlocked. When the door 9 is open, the lock member 15 of the movable panel 3 does not shift from an unlocked state to a locked state. Even if the door 9 abuts to the lock member 15 which is locked without locking the door 9, the lock member 15 is damped by a compression coil spring to move, thus achieving a normal locked state.
