Description

  The present invention relates to a boarding bridge used for getting passengers, occupants, and the like on and off an aircraft from a terminal building.

  Conventionally, boarding bridges are often used in airports and the like. The boarding bridge is connected, for example, to a terminal building at the airport and to an aircraft that stops at the apron. With the boarding bridge being bridged between the terminal building and the aircraft, passengers can get on and off the aircraft from the terminal building via the boarding bridge.

  The boarding bridge is a telescopic walkway, a cab provided at the tip of the walkway, and connected to the entrance of the aircraft, and a rotunda provided at the rear end of the walkway and connected to the terminal building. And The cab is configured to be rotatable around a vertical axis so that the direction can be changed in accordance with the entrance of the aircraft. The front part of the cab is opened forward to be connected to the entrance of the aircraft. On the other hand, the side of the cab needs to be covered with some member. However, since the cab rotates as described above, simply providing a wall on the side of the cab causes the wall to turn with the rotation of the cab, and a part of the passage between the walking passage body and the cab is reduced. There is a risk that the wall will be blocked by the wall. Therefore, conventionally, a slat curtain that can be wound is provided on the left and right sides of the cab. Patent Literatures 1 and 2 disclose a boarding bridge provided with such a slat curtain. When the cab rotates clockwise, the right slat curtain is wound on the right winding drum, and the left slat curtain is unreeled from the left winding drum. On the other hand, when the cab rotates counterclockwise, the left slat curtain is wound on the left winding drum, and the right slat curtain is unreeled from the right winding drum.
