Title:
STAIRWAY ELEVATOR
Document Type and Number:
Japanese Patent JPH0733362
Kind Code:
A
Abstract:
PURPOSE: To simplify the fitting work of a car to a tractor installed on a stairway and prevent the connection between the car and the tractor from being simply removed.
CONSTITUTION: A lever member 173 fitted to a car side is turned down, and a clamp member 171 is coupled with a shaft member 42 on a tractor 20 side. The lower end section of a lock lever 43 is kept in contact with a stopper section in this coupled state, and the optical path of a photo-sensor 137 is blocked. Even if the clamp member 171 tends to be rotated counterclockwise for some cause, the rotation is prohibited by the lock lever 43. When the lock lever 43 is rotated, the photo-sensor 137 outputs a signal, and a prescribed action for safety is taken.
