STRUCTURE OF PRESENCE CONFIRMATION LOCK
Document Type and Number:
Japanese Patent JP2014141806
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a structure of a presence confirmation lock in which positions of a thumb-turn cover and a ring-shaped detection member which are simultaneously rotated and relatively rotated, respectively, can be held so as to prevent them from being unexpectedly rotated.SOLUTION: A structure of a presence confirmation lock comprises: a lock device in which a locking/unlocking operation is performed by rotating one operation member and an existing thumb-turn 39 which is another operation member, provided on front and rear sides of an opening/closing body; a thumb-turn cover 45 accommodating the another operation member in an idling gap 51 allowing a large rotating operation range larger than a rotating operation range of the one operation member; a ring-shaped detection member 57 which is mounted to the thumb-turn cover 45 in the same rotation center axial line so as to be rotated simultaneously with or relatively to the thumb-turn cover 45 for detecting locking of the lock device from an angle position in a circumferential direction; and a leaf string 71 as an elastic contact member elastically contacting a cover outer circumferential surface 61 of the thumb-turn cover 45 and a ring outer circumferential surface 63 of the ring-shaped detection member 57.
