BACK PRESSURE COPING MECHANISM OF LOCK DEVICE

摘要

PROBLEM TO BE SOLVED: To smoothly unlock and lock without large load to a solenoid when back pressure is applied to a door or the like.;SOLUTION: This back pressure coping mechanism of a lock device includes: a lock member 3 engaged with a striker 3; a stopper part 4 engaged with the lock member; a link part 5 rotated in a body with the stopper part; a solenoid 7 for driving the link part; a first switch 31 for detecting the movement of the lock member 3; and a second switch 37 for detecting the movement of the stopper part 4, wherein when the striker and the lock member engage with each other, the first switch is operated, and when the lock member and the stopper part engage with each other, the second switch is operated. When unlock operation is performed by the solenoid, the first switch 31 is operated, in the case where the first switch 31 is operated and the second switch 37 is operated, abnormality is informed. When the lock operation is performed by the solenoid, the first switch 31 is operated, and the second switch 37 is not operated, abnormality is informed.;COPYRIGHT: (C)2009,JPO&INPIT
