<P>PROBLEM TO BE SOLVED: To provide a lock for fittings, capable of incorporating a detector capable of acquiring a state signal of a lock in a long lock box relatively without a margin in the width in the longitudinal direction of an internal space, and surely acquiring the state signal. <P>SOLUTION: The lock for fittings includes: the long lock box provided in a door; a top joint provided inside the lock box and turned in a locking direction and an unlocking direction by operation force of operation means or/and driving force of a driving source; a dead bolt moved forwards and backwards to/from the lock box on the basis of the turning of the top joint; and a detector for detecting the locking/unlocking state of the lock. The detector comprises: a gear body 20 freely rotatably pivoted to the lock box and provided with a stop part 32 on a part of a peripheral end part; a photosensor 21 disposed near the gear body; and a lever type switch piece 23 pivoted at a part near an intermediate part such that the distal end of a long piece part 23a approaches the photosensor to be in a shielding state and separates from it to dissolve the shielding state and the end part of a short piece part 23b is engaged and disengaged in a pressure state with the stop part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
