SAFETY DEVICE FOR REVOLVING DOOR

PROBLEM TO BE SOLVED: To provide protection for the safety of a person which prevents fatal damage to a human body by making a movable wall surface lessen the impact on the human body when the person is caught within a revolving door, and by forcefully stopping a rotating body by starting up a shutdown device while a stopper is activated by a sensor's reliable detection of collision. SOLUTION: A movable inner wall 4 is mounted on the rotating body 2, and a movable wall surface 7 is mounted on an arc-shaped side wall 6 of the rotating body 2. Then the impact is lessened when the human body H is caught at a doorway 1. The movable inner wall 4 and the movable wall surface 7 are pushed by the pressure. When the movable inner wall 4 and the movable wall surface 7 come off each of the predetermined positions, the sensors 5, 9 reliably detect its motion, and the stopper in synchronization with a drive of the automatic revolving door is activated. Then at the same time, the shutdown device 10 mounted on the circumference of the rotating body 2 is started up, thus the rotating body 2 of the revolving door is forcefully stopped in a fixed position.
