Description

  The present invention relates to a boarding bridge. In particular, the present invention relates to air passenger boarding bridges.

  An air passenger boarding bridge is known as a facility used for passengers getting on and off between an airport terminal building and an aircraft.

  The air passenger boarding bridge includes a tunnel part that forms a walking path for passengers between the boarding gate of the terminal building and the boarding gate of the aircraft. As a result, passengers can get on and off directly between the terminal building and the aircraft.

  By the way, recently, the number of glass-fitted air passenger boarding bridges has increased, and the vitrification of the walls of air passenger boarding bridges has provided passengers with daylighting and a sense of openness. Enjoy it.

  In addition, proposal of vitrification of the wall part of such an air passenger boarding bridge has already been performed (for example, refer patent documents 1 and 2).

  The tunnel portion of the air passenger boarding bridge usually has a plurality of nested tunnels, and the pair of adjacent tunnels slide relative to each other along the walking path while maintaining the mutual lap state. Thereby, a tunnel part is comprised so that expansion-contraction is possible in the longitudinal direction.

  For this reason, there is always a wrap portion between adjacent inner and outer tunnels in the expansion and contraction of the tunnel portion. In this wrap portion, a gap is inevitably generated between the walls of the tunnel, and access to such a gap is not easy, and various inconveniences may occur.

  For example, when installing the above-mentioned glass-lined passenger boarding bridge at airports in cold regions, in order to prevent snow from entering the tunnel from the gap generated in the lap part, the entire outer tunnel is covered with glass. It is preferable to apply. However, with such a glass-walled structure on the entire surface of the tunnel, it becomes difficult to clean the glass at the lap portion. Then, the aesthetics of the air passenger boarding bridge may be impaired due to dirt on the glass of the lap portion.

  Further, even in a standard steel plate tunnel, for example, foreign matter may enter the gap, and in this case, inconvenience occurs in extracting the foreign matter.

  As described above, in the conventional boarding bridge, it is considered that there is still room for improvement since the maintenance of the lap portion is insufficiently established.

  This invention is made | formed in view of such a situation, and it aims at providing the boarding bridge which can improve the maintainability of the lap | wrap part of a nested frame body conventionally.

In order to solve the above problems, the present invention includes a passage member that forms a passage between the terminal and the entrance of the moving body,
The passage member has a pair of nested frame bodies, and the frame members can be expanded and contracted by sliding relative to each other along the longitudinal direction of the passage member while maintaining the lap state between the frames. Provided is a boarding bridge that is configured and has a structure in which at least one wall portion of the pair of frame bodies has an opening structure for a gap formed in a lap portion of the frame bodies when the passage member is fully extended. To do.

  Thereby, the maintainability of the lap | wrap part of a nested frame body can be improved compared with the past.

  Moreover, in the boarding bridge of this invention, you may form the said open structure in the wall part of the inner frame of the said pair of frame.

  Moreover, in the boarding bridge of this invention, a part of said wall part may consist of transparent members, and the said open structure may be formed in the said transparent member.

  In the boarding bridge of the present invention, the frame may be a rectangular parallelepiped. And the rotation fulcrum part for the opening / closing member as the said open structure may be formed in the side wall part of the said rectangular parallelepiped standing perpendicularly | vertically to the floor frame of the said rectangular parallelepiped.

  As described above, in the boarding bridge of the present invention, the maintainability of the lap portion can be improved by using an opening / closing member (for example, opening / closing glass). Therefore, it is convenient for cleaning glass (transparent member) at the lap portion, which is difficult with the conventional passage member.

  In the boarding bridge of the present invention, the frame may be a rectangular parallelepiped. And the fixing | fixed part for attachment / detachment members as the said open structure may be formed in the side wall part of the said rectangular parallelepiped standing perpendicularly | vertically to the floor frame of the said rectangular parallelepiped.

  As described above, in the boarding bridge of the present invention, the detachable member (for example, detachable glass) and other components (for example, a handrail for passengers) disposed in the vicinity of the detachable glass are easily separated from the passage member. it can. Therefore, the boarding bridge according to the present invention is convenient in the assembly work at the site of the boarding bridge.
