  10) When boarding the passenger aircraft 10, the general passenger goes up from the stairway device 22 to the floor member 21F of the boarding passage 21, and boardes the passenger aircraft 10 from the connection deck 52 through the boarding port 10E. The wheelchair user moves to the floor member 21F of the boarding passage 21 by the lifter 23 and boards the passenger aircraft 10 from the connection deck 52 through the boarding port 10E.

The detaching procedure of the boarding / exiting device may be performed in the reverse procedure to the above after the shut-off valve 69 is shut off by the lever to bring the hoisting cylinder 63 into the driving state.
(Effect of hood connection device)
According to the configuration of the hood connecting device 31, both ends of one wire rope 41 are connected to the left and right fixed ends 41 a on the free end side of the hood frame 34, and the middle portion of the wire rope 41 is moved by the retracting cylinder 44. The movable pulley 43c, which is movably latched, is advanced to feed out the wire rope 41, the bellows member 33 is unfolded, the hood frame 34 is tilted forward to expand the bellows member 33, and the hood frame 34 is moved to the boarding entrance 10E. It is made to contact the upper body 10F. At this time, since the wire rope 41 is movably hooked by the movable pulley 43C at the intermediate portion, the wire rope 41 is moved to the left and right sides so that the connecting end 41a is movable in the front-rear direction. It is possible to follow the inclination in the front-rear direction on both sides, and there is no gap between the body 10F and the hood frame 34. Therefore, even if the entrance / exit passage 21 is inclined with respect to an axis perpendicular to the opening surface of the boarding opening 10E with a simple structure, the hood frame 34 can be uniformly contacted with the airframe 10F, and boarding with the boarding entrance 10E during stormy weather. It is possible to reliably prevent wind and rain from blowing at the connecting portion with the passage 21.

  In addition, since the slide roof 32 that can move forward by its own weight is provided between the constituent member of the boarding passage 21 and the bellows member 33 via the forward inclined rail 36 and the thrust bearing 37, the wire rope 41 is fed out by the retracting cylinder 44. Thus, the slide roof 32 can be advanced. As a result, an exit / exit device dedicated to the slide roof 32 is not required, and a long exit / exit stroke of the hood frame 34 can be secured. Therefore, a sufficient stopping distance from the passenger aircraft 10 to the vehicle body can be ensured, and the connection work can be performed safely. Furthermore, the slide roof 32 that can be advanced by its own weight can be easily installed in the boarding passage 21 by the forwardly inclined rail 36 and the thrust bearing 37.

  Furthermore, in the hood retracting device 35, the wire rope 41 can be smoothly drawn out and retracted via the guide pulley group 42 and the driving pulley group 43, and the slide roof 32 can be smoothly withdrawn and retracted by the wire rope 41. The bellows member 33 can be expanded and contracted, and the hood frame 34 can be tilted forward and erected.

  Further, the movable adjustment pulley 42C and the fixed adjustment pulley 42D stretch the wire rope 41 between the upper and lower forward inclined rails 36 in parallel with the forward inclined rail 36, and push and pull the wire rope 41 in parallel with the forward inclined rail 36. Thus, the slide roof 32 can be moved forward and backward stably and smoothly.

(Effects of deck hoisting device)
According to the configuration of the deck hoisting device 61, the connection deck 52 is detected by the limit switch 65 in the preparation posture (c) while the connection deck 52 is lying down from the storage posture (a) to the use posture (b). By operating the shut-off valve 69 based on the detection signal to connect the expansion chamber 63r and the contraction chamber 63f of the undulation cylinder 63, the undulation cylinder 63 can be expanded and contracted, and the connection deck 52 is brought into a free state where it can be lowered. The connection deck 52 is lowered by its own weight and the tip end is landed on the floor of the boarding entrance 10E. Therefore, even if the height of the floor portion of the boarding entrance 10E is changed, the front end portion of the connection deck 52 can be reliably landed on the floor portion of the boarding entrance 10E. Even in the use posture (A), since the hoisting cylinder 63 is kept in the free state when the shut-off valve 69 is at the II position, the boarding port 10E according to the displacement of the fuselage 10F due to passenger boarding and unloading passengers and loading / unloading of cargo. Even if the floor part of the boarding port is displaced up and down, the connection deck 52 can be displaced up and down following the floor part of the boarding port 10E, and a gap is generated between the floor part of the boarding port 10E and the connection deck 52. There is no such thing.

  Further, the shutoff valve (free operation valve) is operated by the detection signal of the limit switch 65 to connect the pressure oil supply / discharge pipes 68A and 68B to each other by the bi-pipe 71, and the surplus oil supply / discharge pipe 75 connects to the piston rod. By sucking and discharging the excess oil in the volume to the oil tank 76, the hoisting cylinder 63 can be held in a telescopic manner, and the connection deck can be brought into a free state that can be raised and lowered. Further, the lowering speed and the following speed of the connection deck 52 in the free state can be adjusted by the variable throttle valve 73 interposed in the inlet-by pipes 70a and 70b, and the connection deck 52 is lowered at an arbitrary speed and passed over. Can do.

(Effect of deck shift device)
According to the above configuration, the connection deck 52 in the retracted posture (A) stood by the deck hoisting device 61 is laid down and before the preparation posture (C), the front end of the connection deck 52 is connected to the boarding entrance 10E or the opening / closing door 10G. The intermediate adjustment posture (d) approaching the door rail 10S with the door is temporarily stopped, the deck shift cylinder 87 of the deck shift device 81 is actuated to shift the connection deck 52 in the width direction, and the tip of the hand rail with the door The position can be adjusted so as not to touch 10S or the like. Therefore, even when the position at which the vehicle body 11 stops with respect to the boarding port 10E is shifted and the connection deck 52 of the boarding passage 21 and the boarding port 10E are shifted in the width direction, the deck shift device 81 causes the connection deck 52 to be moved. By shifting, the tip end portion of the connection deck 52 can be accurately passed over the floor portion of the boarding opening 10E, and the connection deck 52 does not come into contact with the handrail 10S with a door.

  Further, since the movable handrail mechanism 84 having the movable floor handrails 89R and 89L is provided on the floor member 21F in the front part of the boarding passage 21, the movable floor handrail is corresponding to the connection deck 52 shifted in the width direction. 89R and 89L can be swung and the front free ends thereof can be adjusted to positions closest to the deck handrails 55R and 55L and fixed by the handrail attachment / detachment tool 90. Thereby, even if the connection deck 52 is shifted in the width direction, it is possible to safely get on and off without causing a large gap between the deck handrails 55R and 55L and the movable floor handrails 89R and 89L.
