This boarding bridge has a telescopic tunnel with a hollow part where passengers can move, a rotunda connected to the airport terminal building entrance and exit, and a forward and reverse rotation at the entrance and exit (door) of the aircraft. It is composed of a cab that is freely connected, and a drive comb comprising a pair of struts that are rotatably provided on both sides of the tunnel aircraft and are provided with traveling tires below. This boarding bridge forms a bridge with a certain height from the apron of the airport and is also called a boarding bridge.

  On the other hand, in recent years, LCC terminals and local airports have been installed on aprons (places where aircraft are parked) when getting on and off the aircraft in order to reduce user comfort, security, and cost. Attention has been focused on utilizing a so-called apron roof, which is a mobile structure.

  FIG. 1 schematically shows the apron roof disposed on the aircraft side, FIG. 2 shows the apron roof accommodated, and FIG. 3 schematically shows the apron roof structure (see Patent Document 1, etc.). In the example shown in FIG. 3, the apron roof structure includes an omnidirectional unit (fixed) or a telescopic unit A on the building (airport terminal) side, a plurality of telescopic units B that can be stretched according to the moving distance, and a tip roof portion. Further, the roof extends to cover the aircraft entrance / exit and the staircase portion, and a tip unit C is attached to the side of the tip unit C.

And the adjacent expansion-contraction unit B is pin-coupled, respectively.

  By installing an apron roof with such a structure, passengers can move between airport terminal buildings and aircraft without being affected by the weather (rain and strong sunlight). Anti-collision and security measures are expected.

  By the way, the apron roof is unfolded in a straight line or with a curve or the like that matches the aircraft stop position, and must be housed in the same track as when unfolded. However, because the apron roof is extended and retracted using an electric tow truck, it is difficult to store the apron roof on the same track as when the handle is operated, and the extension unit is deformed as shown in FIG. was there.

  FIG. 6A shows a state in which the apron roof is deployed in a straight line, and shows a state in which the apron roof is deployed normally. FIG. 6B shows a case in which the apron roof is also deployed in a straight line. In this state, the directions of the respective expansion and contraction units are disjoint and show a state in which distortion occurs. The state in which this distortion occurs is called a jackknife state, and if the electric towing vehicle continues to be operated in a state in which the distortion has occurred during deployment, the apron roof may be damaged. As a cause of the orientation of each expansion / contraction unit being different, the direction of the wheels attached to the expansion / contraction unit is not uniform.

  FIG. 7A shows a state where the apron roof is developed in a curved shape, and shows a state where the apron roof is normally developed. FIG. 7B shows a state where the apron roof is developed in a curved shape. Then, the directions of the respective expansion and contraction units are separated, and a state where distortion occurs and a jack knife state are shown.

  The jackknife condition can also occur when storing the deployed apron roof. FIG. 8A shows a state in which the apron roof is normally stored, and FIG. 8B shows a state in which a jack knife state has occurred.

  When such a deformation of the expansion / contraction unit, that is, a jack knife state occurs, as shown in FIG. 9A, a failure or the like in which the scissor bar is detached from the slide rail is caused. FIG. 9B shows a state in which the slide rail is slid with the scissor bar in a normal state. If the scissor bar is removed from the slide rail as shown in FIG. 9 (a), the apron roof of the next flight cannot be used, and when using the spot, it is necessary to arrange a bus or to guide the passengers with several guards. . In addition, labor and time are required to repair the apron roof.
