Abstract

PURPOSE: To surely confirm locking, in order to enhance the security by providing such an arrangement that a sensor is not energized, unless locking is made by a crescent, even though double sliding doors are locked. CONSTITUTION: A mating frame 17 for an interior side sliding door incorporates first and second sensors 30, 32, and a mating frame 18 for a crescent body 22, and an exterior side sliding door 14 incorporates magnets (or magnetic materials) 31, 33. A coil 34, which changes its state depending upon whether or not the sensors 30, 32 are energized, is attached to the upper part of the frame 17, and a coil 35 facing the coil 34 which is made sensitive thereto is attached to a side frame member 12 of the stationary frame. Even though the doors are closed, the coil 34 will not be short-circuited, unless the handle 29 is locked, and accordingly no resonance occurs. Thereby it is possible to confirm whether or not locking is made.
