Kind Code:
A1
Abstract:
The present invention relates to a safety device for protecting a human hand from getting jammed by, when the hand is jammed in a gap between an elevator door and a door frame, controlling the opening and closing of a door while reducing the impact. The device comprises: a stationary frame (20) having a U-shaped cross section and installed over the entire length of a stepped portion of a door frame (10) of an elevator door between the door frame (10) of the elevator door and an elevator hall door (D); a plate-shaped rotating frame (30) rotatably installed at one end of the stationary frame (20); an actuating pin (40) which is mounted on the stationary frame (20) so as to support the back face of the rotating frame (30), is supported by a spiral spring (S), is pushed into the stationary frame (20) by the rotation of the rotating frame (30), and projects outside the stationary frame (20) by the elastic force of the spiral spring (S); a switch (50) installed inside the stationary frame (20) so as to operate when the actuating pin (40) is pushed into the stationary frame (20) by the rotation of the rotating frame (30); and a controller (C), connected to the switch (50), for stopping the operation of the elevator hall door (D) or controlling the opening/closing speed of the elevator hall door (D) when the switch (50) operates.
