Title: SAFETY DEVICE FOR PREVENTING FINGERS FROM BEING JAMMED IN ELEVATOR
Abstract:
The present invention relates to a safety device for preventing fingers from being jammed in a space between a door and a door frame by installing optical sensors on cage doors of an elevator. Light emitting sensors and light receiving sensors are installed in a one-to-one corresponding manner on only the cage door-side, thereby eliminating the inefficiency of installing optical sensors on all floors of a building.
