Abstract

PROBLEM TO BE SOLVED: To provide a handrail inlet device for a passenger conveyor controlled surely as an emergency time when fingers of infants are caught between a handrail and a handrail inlet of a rail base part. SOLUTION: When fingers are inserted into an inlet part 9 of a movable cylindrical body 15 during an operation, the fingers are caught between a handrail 5 and an edge part of the inlet part 9, a contact 22 is pressed by the caught fingers by advancing of the handrail 5 and the contact 22 is displaced downward. By displacement of the contact 22, an operating rod 18 is rotated and a friction piece 21 is pressed on the handrail 5. By an advancing operation of the handrail 5, the movable cylindrical body 15 is retreated and displaced to the inside of a base part 2 by friction of the friction piece 21 and the handrail 5. By the displacement, a detecting device 14 is operated and an emergency time control is performed for a passenger conveyor. Because retreating and displacing of the movable cylindrical body 15 is not sure, a failure generated by continuing an operating in a state that the fingers are caught is prevented and the caught fingers are made easy to be extracted.
