  • Figure 20B shows an ON state of the switch 90.
  • the accommodation rotation plate 84 is placed above the accommodation rotation axis plate 86, and thus the switch 90 of the safety device is OFF.
  • the accommodation rotation plate 84 is placed on the switch 90 of the safety device.
  • the switch 90 is always ON in the state where the handrail 510 is accommodated.
  • the left and right handrails 520, 530 can be accommodated at the same time by applying the force in the arrow 2 or 4 direction to the accommodation rod 80 or 82.
  • Rotating the accommodation rotation plate 84 in the arrow 3 direction allows the forces in the directions of the arrows 2, 1, and the arrows 4, 5 to be applied, and thus allows the left and right handrails to be accommodated at the same time.
  • the switch 90 of the safety device can be automatically turned on by any of the accommodation methods.
  • the left and right handrails 520, 530 can be installed at a time by applying a force in the direction opposite the above described direction to any of the left and right handrails 520, 530, the accommodation rods 80, 82, and the accommodation rotation plate 84.

  • a relatively high handrail can be provided on top of the elevator cage, and accommodated even in a small space, while preventing interference between the side handrails during accommodation, or interference with the device on top of a cage.
  • the aspect including the automatic accommodation means makes it possible that one of the side handrails is accommodated or installed to allow the other of the side handrails to be accommodated or installed. This reduces time for installing and accommodating the handrail during inspection or other operations of the elevator, and thus reduces overall operation time.
  • the aspect that allows the safety device to be automatically operated or stopped reduces time for operating or stopping the safety device. This also reduces the overall operation time during the inspection or other operations of the elevator.
