The portal-type substrate (not shown) is configured, for example, by connecting the upper ends of a pair of vertical substrates extending in the vertical direction with a horizontal substrate. Tilt means (not shown) is attached to the back surface of the horizontal substrate, and the abutment body 63 can be tilted forward by the tilt means and brought into contact with the body 80. Each of the pair of vertical substrates may be configured by connecting a plurality of plates vertically.

  First and second seal members 64 and 65 are linearly provided on the front surface of the upper portion of the contact body 63. These seal members 64 and 65 are made of rubber having higher bending strength than the contact body cover 71, and can be elastically deformed. For example, as shown in FIG. 3, each of the seal members 64 and 65 includes a flat base portion 64 a and 65 a and a substantially semicircular arc-shaped contact portion integrally provided at the center portion in the width direction of the base portions 64 a and 65 a. 64b and 65b.

  At the airport, the passenger boarding bridge connecting device 6 is brought into contact with the port side of the stopped aircraft. FIG. 4 is a diagram illustrating an example of the first and second sealing members 64 and 65 of the connection device 6 and the entrance / exit 81 of the aircraft and the peripheral portion thereof when the connection device 6 is brought into contact with the port side of the aircraft. It is the figure seen from the passenger boarding bridge side.

  An aircraft body 80 has a rain gutter 83 protruding above a gate 81 provided with a door 82, and the rain gutter 83 is inclined so that the rear side is higher than the front side of the airframe 80. Is provided.

  When connecting the passenger boarding bridge to the aircraft, the front end 61a of the floor 61 of the connection device 6 is brought into contact with the vicinity of the lower edge of the entrance 81 of the aircraft body 80 of the aircraft. Then, the abutting body 63 is tilted forward by the tilting means (not shown) and brought into contact with the body 80. Here, even if the contact body 63 is in contact with the body 80, the contact body 63 does not completely adhere to the body 80, so that rainwater enters a slight gap between the contact body 63 and the body 80.

  When the abutment body 63 abuts against the airframe 80, as shown in FIG. 4, even if the rain gutter 83 intersects with the second seal member 65, the first seal member 64 remains above the gutter 83. If it is in contact, rainwater can be prevented from entering the entrance 81 by the first seal member 64.

  Further, even if the rain gutter 83 intersects with the first seal member 64, if the second seal member 65 is in contact with the lower side of the gutter 83, rainwater is allowed to enter the entrance / exit 81 by the second seal member 65. Can be prevented from entering.

  In an aircraft, not only the height of the entrance / exit 81 differs depending on the model, but also the size of the entrance / exit 81, the distance between the entrance / exit 81 and the gutter 83, the inclination angle and size of the gutter 83, and the like, Both the second sealing members 64 and 65 may cross the rain gutter 83 and come into contact with the airframe 80. An example of this case is shown in FIG. FIG. 6 is a view showing a state of the first seal member 64 and the gutter 83 as seen from the direction of the arrow 100 in FIG. In FIG. 6, the rain gutter 83 has a square cross section. However, the present invention is not limited thereto, and for example, there is a gutter 83 having an L shape in cross section.

  As shown in FIG. 6, gaps S <b> 1 and S <b> 2 are formed at a portion where the first seal member 64 and the gutter 83 intersect. Similarly, gaps S3 and S4 (FIG. 5) are also formed at a portion where the second seal member 65 and the gutter 83 intersect.

  In FIG. 5, rainwater that has entered the gap S <b> 1 at the upper part of the intersection of the first seal member 64 and the rain gutter 83 further passes through the gap S <b> 3 and flows down along the gutter 83 as indicated by the arrow 91. No entry into the entrance 81 below the gutter 83. In addition, the rainwater that has entered the gap S2 at the lower part of the intersection of the first seal member 64 and the rain gutter 83 reaches the second seal member 65 and then reaches the second seal member 65, as indicated by arrows 92 and 93. Since it flows down along the seal member 65, it does not enter the entrance 81.

  On the other hand, when the second seal member is in contact with the airframe 80 in a state inclined in the direction opposite to the above, it is impossible to prevent rainwater from entering the entrance 81. FIG. 7 shows an example in which a seal member 66 inclined in the direction opposite to the second seal member 65 is provided. In this case, the rainwater that has entered the gap S1 at the upper part of the intersection of the first seal member 64 and the rain gutter 83 flows down along the gutter 83 as in the case of FIG. It does not enter the entrance / exit 81. However, after the rainwater that has entered the lower gap S2 at the intersection of the first seal member 64 and the rain gutter 83 reaches the lower seal member 66, as shown by arrows 94, 95, 96, this seal Since it flows along the member 66 and further passes through the gap S4 and flows down to the bottom of the gutter 83, it enters the entrance 81 below the gutter 83.

  In the present embodiment, the second seal member 65 is always attached to the airframe 80 in an inclined state having a downward slope from the front to the rear of the aircraft. Since it is provided, it is possible to reliably prevent rainwater from entering the entrance 81.

  In the present embodiment, the first seal member 64 of the horizontally long portion 63c has a mountain shape, but the present invention is not limited to this. For example, in the horizontally long portion 63c, the first seal member 64 may be provided so as to be inclined in the same direction as the second seal member 65. For example, the first seal member 64 may be provided in parallel with the second seal member 65.

  Further, as in the present embodiment, in the connection device 6 provided in the passenger boarding bridge, the connection device 6 is not necessarily in contact with the airframe 80 in a state where the longitudinal direction 200 of the horizontally long portion 63c of the contact body 63 is in the horizontal direction. Not necessarily. The height of the entrance / exit 81 from the road surface varies depending on the type of aircraft. In the passenger boarding bridge, the tunnel part 4 may incline in order to cause the drive column 7 to expand and contract in the vertical direction to bring the connecting device 6 into contact with the fuselage 80 according to the height of the entrance 81 of the aircraft. . Further, the passenger boarding bridge is configured such that the gradient of the tunnel portion 4 is 1/12 or less from the viewpoint of barrier-free.

However, the tunnel portion 4 has an upward slope in the direction from the rotander 2 to the cab 5, and the cab 5 is moved from the state in which the slope is 1/12 and the connection port 6 a of the connection device 6 is directed forward. When the connection device 6 is brought into contact with the fuselage 80 in the state of being rotated 90 degrees counterclockwise, the longitudinal direction 200 of the laterally long portion 63c is 1/12 at the maximum from the front to the rear of the aircraft. It becomes the direction which has an ascending slope. This state is a state in which the horizontally long portion 63c of the abutting body 63 is in contact with the airframe 80 in an inclined state having a maximum ascending slope from the front to the rear of the aircraft.

  Even in such a case, it is preferable that the second seal member 65 of the horizontally long portion 63c is in an inclined state having a downward slope from the front to the rear of the aircraft and is brought into contact with the airframe 80. That is, even in such a case, as shown in FIG. 1, when viewed from the front, the second seal member 65 is in the longitudinal direction 200 of the horizontally long portion 63c that is in the horizontal direction (in other words, Preferably, it has a slope that rises to the right (with respect to the surface of the floor 61). And it is more preferable that it is provided so that the gradient may become larger than 1/12.

  In the above description, it has been described that the floor 61 of the connecting device 6 is in a fixed state and the surface of the floor 61 is always on the same plane as the surface of the floor 51 of the cab 5, but the floor 61 can be bent or inclined. Even if the front end 61a of the floor 61 is inclined with respect to the surface of the floor 51 of the cab 5 so that the front end 61a of the floor 61 is always in a horizontal state and can be brought into contact with the airframe 80. Good.

  Including such a case, the inclination of the second seal member 65 of the horizontally long portion 63c will be described in detail as follows. That is, the connection port 6a formed with the peripheral edge by the gate-shaped contact body 63 and the front end 61a of the floor 61 is in a state in which it is oriented in the same direction as the direction from the rotander 2 to the cab 5 in a plan view. In the state where the gate-shaped contact body 63 is in an upright posture, the second seal member 65 provided on the front surface of the horizontally long portion 63c of the contact body 63 has a right side with respect to the horizontal plane when viewed from the front. It is provided to have a rising slope. It is more preferable that the gradient is provided to be greater than 1/12.

  And the connection apparatus 6 in this embodiment is provided in the front end of the cab 5 of a passenger boarding bridge. Here, the passenger boarding bridge is connected to the rotander 2 connected to the entrance / exit of the terminal building, and one end is connected to the rotander 2 and can swing up and down with the rotander 2 as a base end, and is telescopically fitted. A telescopic tunnel portion 4 comprising a plurality of tunnels, and a cab 5 provided at the other end of the tunnel portion 4 and having a front end rotatable about a rotation axis Q perpendicular to the surface of the floor 51 of the tunnel. have. The rotation axis Q is perpendicular to the expansion / contraction direction of the tunnel portion 4 (longitudinal direction of the tunnel portion 4).

  In the present embodiment, the connection device 6 provided in the passenger boarding bridge has been described as an example of the aircraft boarding / alighting connection device. However, a configuration in which the same connection device 6 is applied to a roofed lap-top car is also possible. is there. When applied to the trap car, the contact body 63 and the floor 61 are maintained in a state where the surface of the floor 61 of the connecting device 6 is maintained in a horizontal plane and the longitudinal direction 200 of the laterally long portion 63c is maintained in the horizontal direction. Since the front end 61a of the horizontal contact portion 63 is in contact with the airframe 80, the second seal member 65 of the horizontally long portion 63c is inclined upward to the surface (horizontal plane) of the floor 61 when viewed from the front (aircraft side). As long as the slope is 1/12 or less.
