PURPOSE:To enhance safety by indicating an abnormal condition in case of emergency such as sudden illness and the like in a rest room after a door has been closed with an interior closing switch actuated, letting a lock mechanism be released, and opening the door with an exterior actuation section actuated. CONSTITUTION:When a door 2 is closed with an interior closing switch 4b actuated at an interior actuation section 1. within a rest room 1, a door is locked by a lock mechanism, and concurrently an in-use lamp 3c and a lock lamp 4C are lighted. When a call switch 7 is actuated as an user feels bad, the lock mechanism is released, and the lamps 3c and 4c flicker, a helper and the like thereby actuates an exterior open switch 3a, and open the door 2. Besides, if the user loses consciousness after the door 2 has been closed, after a specified period of time has elapsed, an abnormal detection signal is detected by a timer circuit so as to allow the lock mechanism to be released, and let the lamps 3c and 4c flicker. With this constitution, even in the case of emergency such as sudden illness within the rest room, a patient can be found in an early stage, and relieved. Moreover, the acts of mischief within the rest room can be thereby prevented. |
