  • the link 4 is rotated to be separated from the switch 8 and the switch 8 is operated.
  • a detection signal of the switch 8 is sent to the control device, and the control of the control device reverses the door panel 1 from the closing operation to the opening operation.
  • the switch 8 may be of a type that operates in contact with the link 4 when the safety shoe 2 is pressed.

Therefore, the force 52 for pushing the safety shoe 2 may be extremely small.
  • the counterweight 42 increases the moment of force acting on the link 4 in the direction in which the safety shoe 2 is pushed. As a result, the force 52 for pushing the safety shoe 2 can be reduced.
  • FIG. 4 is an enlarged view showing what kind of force and moment of force are applied to the link 4 and the safety shoe 2 when the door panel 1 performs an operation of closing the entrance.
  • the counterweight 42 increases the moment of the force acting on the link 4 in the direction in which the safety shoe 2 protrudes. This can prevent the safety shoe 2 from being pushed in and causing a malfunction.
  • the counter weight 42 causes the link 4 to increase the moment of force acting on the link 4 in the direction in which the safety shoe 2 is pushed when the safety shoe 2 is pushed. Therefore, even if foreign matter such as a loose string is caught in the door of the elevator, foreign matter can be detected even if the safety shoe 2 is pushed in with a small force.
