However, small aircraft other than the planned aircraft may also use PBB that matches the body shape of the mainstream aircraft. At this time, the tip of the cab of the PBB may not be completely joined to the small regional machine. However, if a PBB dedicated to regional aircraft is introduced as a PBB, the boarding gate where the PBB is placed can only be used for regional aircraft, and the dedicated spot will be fixed, and costs such as the introduction of a new PBB and the renovation of the airport building will be required. There is a disadvantage in terms of. Therefore, in order to enable the conventional PBB for large and medium-sized aircraft to be used for regional aircraft, it would be advantageous if an intermediary device between the cab and the aircraft could be provided without the need for renovation of the current airport building.

An aircraft having an aircraft boarding / alighting door that rotates around the lower edge of the boarding / alighting door to open the door opening and a handrail placed on the edge of the stairs arranged on the inner surface of the boarding / alighting door, and a boarding bridge A boarding bridge adapter used between the above, the boarding bridge adapter is a main body portion having a front extending portion and a rear extending portion, and the rear extending portion is the floor surface of the boarding bridge.

The slope plate 3 includes a front extension plate portion 3a and a rear extension plate portion 3b so as to extend without a step from the front extension plate portion 3a in the direction opposite to the front extension plate portion 3a. The front extension plate portion 3a is arranged above the front extension portion 4a of the main body portion 4, and the rear extension plate portion 3b is arranged above the rear extension portion 4b of the main body portion 4. The rear extending portion 4b of the main body portion 4 comes into contact with the floor surface 41 (cab portion floor surface) of the PBB 40. The front extension portion 4a of the main body portion 4 is located on the floor of the door opening 30a of the aircraft 30 from a position lower than the rear extension portion 4b, that is, the floor surface 41 (cab portion floor surface) of the PBB 40 (position at which a step is formed). It extends toward the surface so as to form a slope.

The inclination of the slope plate 3 (the angle formed by the front extension plate portion 3a and the rear extension plate portion 3b) is such that when the tip of the front extension plate portion 3a is installed on the floor surface of the door opening 30a of the aircraft 30. The rear extension plate portion 3b is at an angle at which the floor surface 41 (cab portion floor surface) of the PBB 40 contacts. The front extension plate portion 3a extends from the rear extension plate portion 3b from the floor surface 41 (cab portion floor surface) of the PBB 40 toward the floor surface of the door opening 30a of the aircraft 30 so as to be lowered. The inclination of the slope plate 3 (the angle formed by the front extension plate portion 3a and the rear extension plate portion 3b) is such that when the tip of the front extension plate portion 3a is installed on the floor surface of the door opening 30a of the aircraft 30. The rear extension plate portion 3b is at an angle at which the floor surface 41 (cab portion floor surface) of the PBB 40 contacts.

Wheels 6 are attached to the lower part of the main body 4. The wheels 6 can travel on the floor surface 41 of the PBB 40 toward the aircraft 30, whereby the boarding bridge adapter 1 can be supported by the wheels 6 and move to the installation position of the PBB 40. The wheel 6 is located below the slope plate 3. The wheel 6 can move the boarding bridge adapter 1 back and forth in a state where the front extension plate portion 3a and the rear extension plate portion 3b of the slope plate 3 do not come into contact with the floor. The main body on the side of the rear extension plate portion 3b with respect to the wheel 6 is provided with a slide member 7 to be attached so that the rear extension plate portion 3b has an angle with respect to the extending direction. The slide member 7 is attached so as to extend obliquely from the wheel 6 toward the rear extension plate portion 3b. That is, the slide member 7 is fixed so as to extend diagonally downward in the direction from the PBB 40 to the aircraft 30 with respect to the surface of the rear extension plate portion 3b.

The positional relationship between the wheel 6 and the slide member 7 will be described with reference to FIGS. 5 to 7. FIG. 5 is a diagram showing the vicinity of the wheel 6 in a state where the boarding bridge adapter 1 is moving on the floor surface 41 of the PBB 40 by the wheel 6. FIG. 6 is a diagram showing a state in which the wheel 6 exceeds the floor surface 41 of the PBB 40 and the slide member 7 is in contact with the floor surface 41 of the PBB 40. FIG. 7 is a diagram showing a state in which the slide end 7a of the slide member 7 is in contact with the floor surface 41 of the PBB 40.

As shown in FIG. 5, the wheel 6 travels on the floor surface 41 of the PBB 40 toward the aircraft 30, and then separates from the floor surface 41 of the PBB 40 by contact with the floor surface 41 of the PBB 40. Up to this stage, the boarding bridge adapter 1 is supported by the wheels 6 (FIG. 5). Further, when the wheel 6 advances and the boarding bridge adapter 1 exceeds the floor surface 41 of the PBB 40, the wheel 6 is separated from the floor surface 41 of the PBB 40, and the slide member 7 is separated from the floor surface 41 of the PBB 40 and the upper edge 41a of the end of the floor surface 41 of the PBB 40. The contact point between the slide member 7 and the upper edge 41a of the end slides to the slide end 7a of the slide member 7 (FIG. 6). When the contact point reaches the end of the slide 7a, the rear extension plate portion 3b of the slope plate 3 comes into contact with the floor surface 41 of the PBB 40, and the boarding bridge adapter 1 is supported (FIG. 7).

In the boarding bridge adapter 1, when the rear extending portion 4b of the main body 4 comes into contact with the floor surface 41 of the PBB 40, the tip edge of the front extending portion 4a of the main body 4 is directly in contact with the floor surface of the door opening 30a. , A damper plate 5 is provided to prevent line contact. The damper plate 5 is rotatably attached around the rotation shaft 5a. In the damper plate 5, the tip 5b of the damper plate and the rear end 5c of the damper plate are swung around the rotation shaft 5a, and the damper plate 5 is the door opening 30a of the aircraft 30 regardless of the inclination angle of the boarding bridge adapter 1. It is designed to come into contact with the floor surface of the building. A damper plate 5 is located between the tip 3c of the front extension plate portion 3a of the slope plate 3 and the floor surface of the door opening 30a, and the front extension plate of the slope plate 3 is extended via the damper plate 5. The tip of the portion 3a comes into contact with the floor surface of the door opening 30a of the aircraft 30. Further, even if the damper plate 5 is not arranged and the tip 3c of the forward extending plate portion 3a of the slope plate 3 comes into direct contact with the floor surface of the door opening 30a of the aircraft 30 without passing through the damper plate 5. Good.

When the damper plate 5 is arranged, the boarding bridge adapter 1 is placed on the floor surface 41 of the PBB 40 when the boarding / alighting door 31 of the aircraft 30 is opened outward with the lower edge thereof as the center, as in the regional aircraft. The damper plate 5 has an arbitrary inclination angle when the wheels 6 are moving while being in contact with each other (the state shown in FIG. 3). For example, the damper plate 5 has an inclination angle close to the inclination of the slope plate 3. When the boarding bridge adapter 1 is attached to a predetermined position on the floor surface 41 of the PBB 40, the tip 5b of the damper plate 5 first comes into contact with the floor surface of the door opening 30a of the aircraft 30. When the angle of the boarding bridge adapter 1 is changed to install the boarding bridge adapter 1 in a predetermined position, the tip 5b of the damper plate 5 is pushed, the damper plate 5 is rotated, and the rear end 5c of the damper plate 5 is moved. , Coming down toward the floor of the door opening 30a of the aircraft 30. Then, when the boarding bridge adapter 1 is completely installed at a predetermined position, the entire surface of the damper plate 5 comes into contact with the floor surface of the door opening 30a of the aircraft 30. The tip 3c of the front extension plate 3a of the slope plate 3 comes into contact with the damper plate 5, and the tip 3c of the front extension plate 3a of the slope plate 3 passes through the damper plate 5 to the door opening 30a of the aircraft 30. Contact the floor.

In an aircraft 30 such as a regional aircraft in which the door 31 of the aircraft 30 rotates outward around the lower edge thereof to open the door opening 30a, the door 31 is completely opened. Then, the upper edge of the handrail 33 of the airstair 32 is attached so as to extend diagonally downward from the door opening 30a in the horizontal direction along the diagonally downward direction in which the steps of the airstair 32 are continuous. The handrail 2 of the boarding bridge adapter 1 extends from the PBB 40 toward the aircraft 30 along the longitudinal direction of the main body 4. Here, the boarding bridge adapter 1 is attached to the PBB 40, that is, the rear extending portion 4b of the main body 4 comes into contact with the floor surface 41 of the PBB 40, and the tip of the front extending portion 4a of the main body 4 (damper). When the plate 5 is arranged, the state in which the damper plate 5) is in contact with the floor surface of the door opening 30a of the aircraft 30 is defined as the “mounting state”.

In the mounted state of the boarding bridge adapter 1, the handrail 2 of the boarding bridge adapter 1 is arranged above the air steer 32 of the regional aircraft. That is, when the handrail 2 of the boarding bridge adapter 1 is attached, the lower end 2c of the front edge 2a on the side closest to the aircraft of the handrail 2 of the boarding bridge adapter 1 is air-steered when the boarding / alighting door 31 is completely opened. It is located above the upper edge of the handrail 33 of 32. The handrail 2 of the boarding bridge adapter 1 extends from the lower end 2c of the front edge 2a on the side closest to the aircraft of the handrail 2 of the boarding bridge adapter 1 to the inclination angle (horizontal) of the lower edge of the handrail 2 of the boarding bridge adapter 1. The inclination angle toward the lower side with respect to the direction) is smaller than the inclination angle of the upper edge of the handrail 33 of the airstair 32 (the inclination angle toward the lower side with respect to the horizontal direction). As a result, even in the "mounted state" of the boarding bridge adapter 1, it does not interfere with the handrail 33 of the air steer 32 of the regional aircraft. That is, regardless of the width of the handrail 33 of the airstair 32 of the airframe, the boarding bridge adapter 1 can be attached without removing the handrail 33 of the airstair 32.
