Description

  The present invention relates to a boarding bridge used for passenger movement between a terminal building and an aircraft or a ship (passenger ship).

  For example, a boarding bridge is known as equipment used for passengers getting on and off between an airport terminal building and an aircraft. When the boarding bridge is connected to the boarding / alighting part of the aircraft, a passage to the aircraft is formed using the boarding bridge. As a result, passengers can get on and off directly between the terminal building and the aircraft.

  By the way, the lower end of the door of the boarding / alighting part of the aircraft is located below the floor part of the boarding / alighting part of the aircraft, so if the step between the flooring of the boarding / alighting part and the boarding bridge is eliminated, this door It will be difficult to open and close the door by hitting the boarding bridge.

  For this reason, it is necessary to make the position of the boarding bridge lower than the position of the floor part of the boarding / alighting part, for example, about several hundreds of mm. However, in this case, the level difference between the floor portion of the boarding / alighting portion and the passage of the boarding bridge may be an obstacle to passengers getting on / off. For example, it is not easy for a passenger in a wheelchair to board an aircraft from a terminal due to the presence of such a step.

  In view of this, a structure has been proposed in which a movable floor is provided at the tip of the cab of the boarding bridge and the movable floor can be raised and lowered (see Patent Document 1).

  In the boarding bridge of Patent Document 1, the tip of the boarding bridge can be connected to the aircraft in a state where the movable floor of the boarding bridge is positioned below the floor of the boarding / alighting part. Thereby, the door of the boarding / alighting part of an aircraft can be opened and closed. Then, after the door is completely opened, the movable floor of the boarding bridge is lifted up to almost the same height as the floor of the boarding / exiting section. Then, since the level | step difference between the floor part of a boarding / alighting part and the movable floor of a boarding bridge is lose | eliminated, the passenger (for example, the passenger who got on the wheelchair) can get off to an movable floor easily from an aircraft. Next, the movable floor of the boarding bridge is lowered to almost the same height as the cab floor. Then, since the level | step difference between the floor part of a cab and a movable floor is lose | eliminated, the passenger can move easily toward the terminal of the passage of a boarding bridge.

JP 2004-155257 A

  However, in the boarding bridge of Patent Document 1, for example, it is necessary to move up and down the movable floor every time a passenger on a wheelchair gets on and off the aircraft, so that the passenger can get on and off smoothly. Therefore, the technique described in Patent Literature 1 still has room for improvement in terms of smooth passenger boarding / exiting.

  Further, when the movable floor is lifted, there is a step between the cab floors on both sides of the movable floor, so that passengers who are in a wheelchair may feel uneasy about whether or not the wheelchair will be removed.

  The present invention has been made in view of such circumstances, and provides a boarding bridge that can reduce anxiety felt by passengers, for example, passengers in wheelchairs, and can smoothly get on and off a moving body. Objective.

  In order to achieve the above object, a boarding bridge according to an aspect of the present invention is provided in a plane of a walking path and the walking path in plan view, and is used for connection to a boarding / alighting part of a moving body. When the passage rises, maintain a state in which there is no substantial step between the other end separated from the one end which is the connection side with the boarding / exiting portion and the walking passage. Ascending the one end side, the elevating passage configured to form a passage including an inclined path between the one end and the other end and having no stepped step, and the elevating path rises. And a protective member that protrudes upward along the side portion of the elevating passage.

  According to this configuration, the other end portion is maintained in a state in which there is no substantial step between the walking passage and the one end portion side is raised, thereby including the ramp between the one end portion and the other end portion and having a stepped shape. And an elevating passage configured to form a passage having no step. Thereby, it is possible to eliminate the step of the connecting portion between the lifting passage and the moving portion of the moving body, and, for example, it is not necessary to move up and down the lifting passage every time a passenger on a wheelchair gets on and off the aircraft, Passengers can get on and off the moving body smoothly.

  Moreover, when the raising / lowering passage raises, the protection member which protrudes upwards along the side part of the raising / lowering passage is provided. Thereby, for example, it is possible to reduce anxiety that the wheelchair may be removed from the lift passage for passengers in the wheelchair.

  Further, the protection member is advanced upward from the passage surface of the lifting passage when the lifting passage is raised, and is the same as or below the passage surface of the lifting passage when the lifting passage is lowered. You may be comprised so that it may evacuate to.

  Further, when the elevating passage is raised, the protective member is advanced upward from the passage surface of the elevating passage, and when the elevating passage is lowered, the protective member is the same as the passage surface of the elevating passage or A first connecting mechanism for connecting the protection member and the lifting / lowering passage for advancing / retreating the protection member according to the lifting / lowering of the lifting / lowering passage may be further provided so as to retreat downward.

  According to this configuration, since the protective member operates in conjunction with the lifting / lowering operation of the lifting / lowering passage by the first coupling mechanism, a dedicated driving device for operating the protective member is not necessary.

  In addition, there is a gap for disposing the protection member between a side portion of the lift passage and the walking passage, and the protection member is retracted to be the same as or below the passage surface of the lift passage. A lid for closing the upper end of the gap may be further provided.

  According to this configuration, dust or the like can be prevented from entering the gap by the lid.

  When the elevating passage starts to rise, the lid is opened to open the upper end of the gap, the elevating passage is lowered, and the protection member is retracted to the same level as or lower than the passage surface of the elevating passage. A second connecting mechanism for connecting the lid and the lifting / lowering passage for opening / closing the lid according to the lifting / lowering of the lifting / lowering passage may be further provided so as to close the lid.

  According to this configuration, since the lid is operated in conjunction with the lifting / lowering operation of the lifting / lowering passage by the second coupling mechanism, a dedicated driving device for opening / closing the lid is not necessary.

  The elevating passage includes an elevating deck having the one end connected to the boarding / alighting portion of the moving body, an elevating mechanism for elevating the elevating deck, and a fixed end portion thereof rotatably attached to the elevating deck. The free end portion is the other end portion, and is configured to be movable in the direction of human movement along the main surface of the walking passage. The free end portion is the main portion of the walking passage as the elevating deck moves. It has a driven slope which moves along a plane and forms the ramp between the elevating deck and the walking passage, and the protection member may be disposed on both sides of the elevating passage.

  According to this configuration, since the height of the lifting deck can be adjusted by a simple lifting movement of the lifting deck, the floor of the lifting deck can be maintained substantially horizontal without being inclined. For this reason, there exists an advantage that it is easy to position with the raising / lowering deck and the floor part of a boarding / alighting part.

  The elevating deck includes a slide mechanism that slides in a person's passage direction, and the elevating deck is moved to the same height as the floor portion of the boarding / alighting unit by the elevating mechanism, and the boarding / alighting portion is You may be comprised so that it may contact | abut.

  According to this configuration, even when a slight gap is generated between the lifting deck and the boarding / exiting part (outer wall) of the moving body, the sliding mechanism can slide to the position where the lifting deck contacts the boarding / unloading part. Such a gap can also be eliminated.

  The walking passage has an inclined floor that adjusts an inclination in the width direction of the elevating deck and the driven slope, and an inclination mechanism that can incline the inclined floor in the width direction, and the inclined floor is viewed in plan view. In this case, the elevating deck and the driven slope may be attached in the plane of the inclined floor.

  According to this structure, when the edge of the floor of a raising / lowering deck and the edge of the floor part of the boarding / alighting part of a moving body are not parallel, both can be paralleled using an inclined floor. For example, even when the drive column of the boarding bridge is being moved, the connecting operation of the lifting deck to the boarding / alighting part can be performed efficiently by performing parallel adjustment between the lifting deck and the boarding / alighting part using the inclined floor.

  The present invention has the above-described configuration, has the effect that it can provide a boarding bridge that can reduce anxiety felt by passengers, for example, passengers in wheelchairs, and can smoothly get on and off a moving body. Play.

(Embodiment)
FIG. 1 is a layout diagram illustrating an example of a boarding bridge system including a boarding bridge according to an embodiment of the present invention.

  As shown in FIG. 1, an air passenger boarding bridge system 1 includes an air passenger boarding bridge 20 (hereinafter abbreviated as “boarding bridge 20”) connected to an entrance of an airport terminal building 10. In the aircraft 11, by using such a boarding bridge 20, there are cases where passengers get on and off efficiently.

  FIG. 2 is a diagram showing an overall configuration of the boarding bridge according to the embodiment of the present invention. In the present embodiment, for example, as shown in FIG. 2, for convenience, the aircraft 11 side of the boarding bridge 20 is “front” and the terminal building 10 side of the boarding bridge 20 is “rear”. Further, the width direction 300 of the boarding bridge 20 is defined as “left” and “right” of the boarding bridge 20. Moreover, in the following description, there are cases in which the “passing direction 200” of the passerby (passenger) of the boarding bridge 20 in the front-rear direction 200 may be referred to.

  As shown in FIG. 2, the boarding bridge 20 is disposed at the rotander (rear circular chamber) 24 connected to the entrance 10 </ b> A of the terminal building 10, the tunnel portion 25 connected to the rotander 24, and the front end of the tunnel portion 25. A cab (front circular chamber) 26 and an auxiliary staircase 23 disposed on the side wall of the tunnel portion 25 in the vicinity of the cab 26.

  The rotander 24 is arranged so that the tunnel portion 25 can swing around a shaft 24A (hereinafter referred to as “vertical axis”) in the vertical direction (perpendicular to the plane of FIG. 2). Arranged for rotation at the end. As a result, the rotander 24 can serve as a seam between the terminal building 10 and the tunnel portion 25.

  The cab 26 is rotatably arranged at the front end portion of the tunnel portion 25 so that the front end portion of the cab 26 can swing to the left and right by the cab 26 itself turning around the vertical axis 26A.

  In this cab 26, an operation panel 30 (see FIG. 3) is installed, and an operator operates various devices (for example, drive columns) of the boarding bridge 20 using a joystick (not shown) of the operation panel 30. it can.

  The auxiliary staircase 23 is installed on the side of the tunnel portion 25 so as to communicate the inside of the tunnel portion 25 with the ground (apron). The auxiliary staircase 23 is used for an operator to enter and exit the cab 26, for example.

  The tunnel portion 25 corresponds to a box-shaped passage member that forms a passenger passage between the terminal building 10 and the boarding / alighting portion 11 </ b> A of the aircraft 11. As shown in FIG. 2, the tunnel portion 25 includes a pair of (adjacent) first and second tunnels 25A and 25B that overlap in a nested manner, and a pair of (adjacent) second and second that overlap in a nested manner. Three tunnels 25B and 25C are provided. In other words, the first tunnel 25A, the second tunnel 25B, and the third tunnel 25C are respectively the same box (cuboid) and have different cross-sectional sizes, and are configured to be incorporated into a telescope in order. Yes.

  The above tunnel portion 25 includes a known slide structure (not shown), whereby the tunnel portion 25 maintains the lap state between the first, second and third tunnels 25A, 25B and 25C. By being relatively slid along the longitudinal direction (front-rear direction), it can be expanded and contracted.

  Further, the drive column 27 is connected so as to sandwich the third tunnel 25C. Therefore, when the drive wheel at the lower end of the drive column travels on the apron, the power of the forward / backward extending / contracting motion (sliding motion) and the swing motion (turning motion) around the vertical axis 24A is transmitted to the tunnel portion 25. Further, such a drive column is configured to be extendable in the vertical direction. Then, the tunnel portion 25 and the cab 26 can swing in the vertical direction with the rotander 24 as the base end by the expansion and contraction motion of the drive column.

  Next, the configuration of the cab 26 of the boarding bridge 20 of the present embodiment will be described in detail with reference to the drawings.

  FIG. 3 is a diagram schematically illustrating a configuration example of a cab used in the boarding bridge according to the embodiment of the present invention.

  As shown in FIG. 3, the cab 26 and the passage of the tunnel portion 25 form a walking passage 31 in which a passenger can move between the terminal building 10 and the aircraft 11 along the passing direction 200.

  The walking passage 31 includes a fixed passage 32 that is integral with the passage of the tunnel portion 25, and an adjustment passage 33 that is used for connection adjustment with the boarding / alighting portion 11 </ b> A of the aircraft 11.

  As described above, the vertical shaft 26A is provided substantially at the center in the width direction 300 of the fixed passage 32, whereby the front end portion of the cab 26 is moved to the left and right as the fixed passage 32 turns around the vertical shaft 26A. Swing exercise.

  The adjustment passage 33 includes a width direction inclined floor 34 (hereinafter abbreviated as “inclined floor 34”), a connection floor 39, an elevating deck 35, and a driven slope 36.

  As shown in FIG. 3, a substantially rectangular opening 34A having a long side in the passage direction 200 is provided in a portion on the right side of the inclined floor 34, and when the inclined floor 34 is viewed from above, the rectangular ascending / descending position is increased. The deck 35 and the driven slope 36 are arranged in the plane of the inclined floor 34 (that is, in the plane of the walking passage 31) so as to cover substantially the entire area of the opening 34A.

  In the boarding bridge 20 of the present embodiment, since various structures can access the back surface of the lifting deck 35 from below through the opening 34A, the lifting driving force and the sliding driving force to the lifting deck 35 are lifted and lowered. Although it can be easily given to the deck 35, details thereof will be described later.

  The elevating passage 21 includes the elevating deck 35 having the bumper 51 and the driven slope 36. A detailed view of the elevating passage 21 and the vicinity thereof is shown in FIG. As shown in FIG. 10, guard plates 101 </ b> A and 101 </ b> B serving as protective members configured to be able to advance above the passage surface of the elevating passage 21 are accommodated on both sides of the elevating passage 21. Guard covers 131A and 131B for covering the entrance / exit are provided. In FIG. 3, the guard plates 101A and 101B, the guard covers 131A and 131B, etc. are omitted and simplified.

  In this embodiment, when the elevating deck 35 of the elevating passage 21 starts to rise, first, the guard covers 131A and 131B are opened (see FIG. 13B), and the upper portions of the guard plates 101A and 101B are from the passage surface of the elevating passage 21. It is configured to advance (protrude) upward (see FIG. 12). Further, when the elevating deck 35 is lowered from the raised state, the guard plates 101A and 101B are lowered immediately before the lowering is finished, the guard covers 131A and 131B are closed, and the original state before the elevating deck 35 is raised ( It is configured so as to return to FIG. Details of the guard plates 101A and 101B and the guard covers 131A and 131B will be described later with reference to FIGS.

<Structure and tilting mechanism of tilted floor 34>
First, the structure of the inclined floor 34 and the inclination mechanism of the inclined floor 34 will be described in detail.

  As shown in FIG. 3, the substantially right triangular connection floor 39 is connected to the fixed passage 32 via the first connection hinge 37 and is also connected to the inclined floor 34 via the second connection hinge 38. For this reason, the inclined floor 34 is also connected (connected) to the fixed passage 32 using the connecting floor 39.

  The second connecting hinge 38 extends linearly from the vicinity of the spherical plain bearing 42 (rod end 42; details will be described later) to the right end of the cab 26 in the direction (width direction 300) substantially orthogonal to the passing direction 200. The first connecting hinge 37 extends linearly from the vicinity of the rod end 42 to the right end of the cab 26 in a direction that forms a predetermined acute angle θ with respect to the traveling direction 200. That is, the region sandwiched between the first connection hinge 37 and the second connection hinge 38 is the connection floor 39.

  Further, as shown in FIG. 3, the screw shaft of the first electric cylinder 43 (screw cylinder) is fixed to the right end portion of the inclined floor 34. Thereby, the right end of the inclined floor 34 can be moved up and down by the stroke of the screw shaft of the first electric cylinder 43 extending and contracting in the vertical direction.

  FIG. 4 is a diagram illustrating a configuration example of the adjustment passage and its peripheral structure as viewed in the YY line in FIG. 3. FIG. 5 is a view showing a configuration example of the spherical plain bearing (rod end) 42 of FIG.

  As shown in FIG. 4, the inclined floor 34 includes a bumper 40 made of synthetic rubber, and the bumper 40 is attached over the entire width direction 300 of the front end portion of the inclined floor 34. That is, the bumper 40 extends in a direction parallel to the second connecting hinge 38.

  As described above, the bumper 40 has a function of reducing the impact when the boarding bridge 20 contacts the aircraft 11 and maintaining the distance between the front end portion of the adjustment passage 33 and the boarding / alighting portion 11A of the aircraft 11.

  Further, as shown in FIG. 4, a support roller 41 (cam follower 41) is attached to the housing 40A of the bumper 40, and a roller holder 41A for pressing the head of the cam follower 41 from above and below is fixed to the fixed passage 32 via a connecting member (not shown). It is connected to. Thereby, the inclined floor 34 can slide parallel to the main surface of the inclined floor 34 with respect to the fixed passage 32 using the cam follower 41.

  On the other hand, as shown in FIG. 5, the housing of the rod end 42 is fixed to the frame 32A of the fixed passage 32, and the rod 42B passing through the ball 42A of the rod end 42 is connected to the inclined floor 34 via a plate material (not shown). Has been. As a result, the rod 42B can face various angles by the spherical slip of the ball 42A, so that the inclined floor 34 can swing freely with respect to the fixed passage 32 using the rod end 42.

  With the above configuration, when the right end portion of the inclined floor 34 moves up and down by the driving force of the first electric cylinder 43, the front end portion of the inclined floor 34 swings around the first connection hinge 37 and the second connection It swings around the hinge 38 as well. As a result, the inclined floor 34 can be inclined in the width direction 300. That is, the inclined floor 34 can perform a seesaw motion around a virtual straight line 400 connecting the cam follower 41 and the rod end 42.

  At this time, the linear line 400 is translated by the sliding motion of the cam follower 41 in the surface of the inclined floor 34 and the free swinging motion of the rod end 42, and the connecting floor 39 is also swung up and down. Therefore, in the boarding bridge 20 of the present embodiment, the seesaw motion of the inclined floor 34 can be performed smoothly.

  As described above, the edge of the inclined floor 34 (that is, the edge of the floor of the lifting deck 35 described later) and the edge of the floor portion 11B (see FIGS. 8 and 9) of the boarding / alighting portion 11A of the aircraft 11 are parallel to each other. If not, the inclined floor 34 can be used to achieve parallelism between the two. For example, the height of the boarding / alighting portion 11 </ b> A of the aircraft 11 varies depending on the size of the aircraft 11. In order to cope with such a change in height, the tunnel portion 25 may be inclined with different vertical heights in the front and rear. In this state, when the fixed passage 32 turns around the vertical axis 26A, the adjustment passage 33 simultaneously swings to the left and right, so that the floor edge of the lifting deck 35 and the edge of the floor portion 11B of the boarding / alighting portion 11A of the aircraft 11 And may not be parallel. In such a case, the seesaw motion of the inclined floor 34 functions effectively.

  Next, an example of the raising / lowering deck 35, the driven slope 36, and its peripheral structure will be described.

  FIG. 6 is a diagram illustrating a configuration example of the adjustment passage and its peripheral structure as viewed in the direction of the line XX in FIG. 3. FIG. 7 is a diagram illustrating a configuration example of the peripheral structure of the adjustment passage as viewed in the direction of the line ZZ in FIG. 6.

  As shown in FIGS. 6 and 7, in the adjustment passage 33 of the boarding bridge 20 of this embodiment, in the vicinity of the opening 34 </ b> A of the inclined floor 34, the lifting mechanism that can lift and lower the lifting deck 35 and the swing that swings the driven slope 36 are swung. A moving mechanism and a slide mechanism capable of sliding in the traveling direction 200 are incorporated.

<Elevating mechanism of lifting deck 35>
Hereinafter, the lifting mechanism of the lifting deck 35 (the lifting mechanism of the lifting passage 21) will be described in detail.

  As shown in FIG. 6, the raising / lowering mechanism of the raising / lowering deck 35 has a second electric cylinder 70 (screw cylinder) and a substantially C-shape (to be precise, a shape close to a semicircle having two bent portions) in plan view. Bracket plate 60.

  The tip of the screw shaft 70 </ b> A of the second electric cylinder 70 is connected to one end of the bracket plate 60 via the first rotation fulcrum 61. The main body 70B of the second electric cylinder 70 is connected to the support bracket 71 via a fourth rotation fulcrum 72, and the support bracket 71 uses appropriate fixing means (such as a support member and a bolt; not shown). It is fixed to the inclined floor 34. Further, a pair of frames 73A and 73B are connected to the bent portion 60A of the bracket plate 60 via the second rotation fulcrum 62 (see also FIG. 7). The frames 73A and 73B are connected to appropriate fixing means (supporting member). And a bolt or the like (not shown). Further, a pair of first and second connecting members 64A and 64B are connected to the other end of the bracket plate 60 via a third rotation fulcrum 63, and the first connecting member 64A is a pin 64C that is passed through a long hole. Is connected to the second connecting member 64B in a swingable manner.

  As shown in FIG. 6 (see also FIG. 7), the elevating mechanism of the elevating deck 35 includes a pair of first and second linear guides 68A including a support frame 65, a table 66, and a rail 67 extending in the vertical direction. 68B and a connecting frame 69 extending in the left-right direction. Here, the support frame 65 is configured in a substantially rectangular annular shape including a pair of first and second frames 65A and 65B extending in the left-right direction and a pair of third and fourth frames 65C and 65D extending in the up-down direction. However, it is not limited to this. For example, the support frame 65 may be formed in a cross beam shape.

  The second connecting member 64B is fixed to a substantially central portion in the left-right direction of the second frame 65B of the support frame 65 using an appropriate fixing means (for example, a bolt). The rails 67 of the first and second linear guides 68A and 68B are fixed to the third and fourth frames 65C and 65D of the support frame 65 using appropriate fixing means (for example, bolts), respectively. ing. Further, the tables 66 of the first and second linear guides 68A and 68B are fixed at appropriate positions on the left and right of the connecting frame 69 using appropriate fixing means (such as a support member and bolts). The connecting frame 69 is fixed to the inclined floor 34 by using appropriate fixing means (such as a support member and a bolt; not shown).

  The elevating deck 35 is supported by the first frame 65A of the support frame 65 via a slide mechanism (details will be described later). Details of the support structure of the elevating deck 35 will be described later.

  With the above configuration, when the stroke of the screw shaft 70 </ b> A of the second electric cylinder 70 extends, the first rotation fulcrum 61 at one end of the substantially C-shaped bracket plate 60 is driven by the driving force of the second electric cylinder 70. It is pushed forward and obliquely downward (see dotted line arrow 500 in FIG. 6). Then, the entire bracket plate 60 rotates around the second rotation fulcrum 62 of the bent portion of the bracket plate 60 (see the dotted arrow 501 in FIG. 6), and thereby the third rotation of the other end of the bracket plate 60. The fulcrum 63 moves upward (see the dotted arrow 502 in FIG. 6).

  As the entire bracket plate 60 rotates, the third rotation fulcrum 63 moves slightly forward. Such forward movement of the third rotation fulcrum 63 is the first connection centered on the pin 64C. This is performed by swinging the member 64A (see FIG. 8).

  As described above, when the third rotation fulcrum 63 of the bracket plate 60 moves upward, the entire support frame 65 also slides upward via the first and second linear guides 68A and 68B, so that the lifting deck 35 can be lifted. (See the two-dot chain arrow 503 in FIG. 6).

  In addition, after raising the raising / lowering deck 35, the support frame 65 and the raising / lowering deck 35 can be lowered | hung by shortening the stroke of the screw shaft 70A of the 2nd electric cylinder 70, but the movement of each part of the raising / lowering mechanism in this case is It can be easily understood by taking the above description into consideration. Therefore, the description of the movement of the lifting mechanism when the lifting deck 35 is lowered is omitted here.

  Thus, in the boarding bridge 20 of this embodiment, the raising / lowering deck 35 is comprised so that it may raise / lower appropriately using the raising / lowering mechanism of the raising / lowering deck 35. FIG.

<Oscillation mechanism of driven slope 36>
Next, the swing mechanism of the driven slope 36 will be described in detail.

  As shown in FIGS. 3 and 6, the front end portion (fixed end portion) of the plate-like driven slope 36 swings to the rear end portion of the lifting deck 35 via the third connection hinge portion 50 (connection swing shaft). It is connected freely. Here, the 3rd connection hinge part 50 is extended in the linear form to the both ends of the raising / lowering deck 35 (following slope 36) in the direction which cross | intersects (in this case, substantially orthogonal) in the passage direction 200.

  Further, the driven slope 36 can swing relative to the lifting deck 35 around the third connecting hinge 50, and the rear end (free end) of the driven slope 36 is, for example, As shown in the partial view 6A of FIG. 6, the driven slope 36 may be placed on the inclined floor 34 in a free state by the action of gravity (self-weight).

  As described above, when the elevating deck 35 is lifted (see the two-dot chain line arrow 503 in FIG. 6), the third connecting hinge portion 50 is also lifted, whereby the angle formed by the main surface of the elevating deck 35 and the main surface of the driven slope 36 is increased. The inclination angle φ of the driven slope 36 corresponding to is continuously increased. At the same time, as shown in the partial view 6A of FIG. 6, the rear end portion of the driven slope 36 moves forward while sliding on the inclined floor 34 (see a two-dot chain line arrow 504 in the partial view 6A).

  Conversely, when the elevating deck 35 is lowered after the elevating deck 35 is lifted, the third connecting hinge portion 50 is also lowered, whereby the inclination angle φ of the driven slope 36 is continuously reduced. At the same time, the rear end of the driven slope 36 moves backward while sliding on the inclined floor 34.

  In this manner, in the boarding bridge 20 of the present embodiment, the inclination angle φ of the driven slope 36 changes as the lifting deck 35 moves up and down (in other words, the driven slope 36 swings relative to the lifting deck 35). ), The rear end portion of the driven slope 36 is configured to move in the front-rear direction. Thereby, the driven slope 36 forms an inclined path between the elevating deck 35 and the inclined floor 34 (walking passage 31).

  In the above description, the case where the rear end portion of the driven slope 36 is placed on the inclined floor 34 in a free state is described as an example of the support structure of the rear portion of the driven slope 36. However, the present invention is not limited thereto. . For example, in the case of FIGS. 11A and 11B described later, another example is used as a support structure for the rear portion of the driven slope 36. In any case, the driven slope 36 is configured such that the rear end portion thereof is movable in the front-rear direction (passing direction 200) along the main surface of the inclined floor 34.

<Sliding mechanism of lifting deck 35>
Next, the slide mechanism of the lifting deck 35 will be described in detail.

  As shown in FIGS. 6 and 7, the slide mechanism of the elevating deck 35 is supported by a third linear guide 83 including a table 80, a rail 81 extending in the front-rear direction, and the table 80 of the third linear guide 83. A pair of first and second urging mechanisms 86A and 86B.

  A notch 80A (see FIG. 7) for preventing contact interference with the bracket plate 60 is provided at the rear end of the center of the table 80.

  The rail 81 of the third linear guide 83 is fixed to the first frame 65A of the support frame 65 using appropriate fixing means (support member, bolts, etc .; not shown).

  Each of the first and second urging mechanisms 86A and 86B includes a cylindrical spring shaft 85 extending in the front-rear direction, a spring 84 (elastic body) fitted around the spring shaft 85, and the spring 84. And a pair of stopper members 87 and 88 that contact the ends.

  Both ends of the spring shaft 85 are threaded, and appropriate fixing means (nuts or the like) are screwed to the both ends to restrict the movement of the stopper members 87 and 88 in the front-rear direction.

  The stopper member 88 on the rear end side of the spring 84 is fixed to the table 80 of the third linear guide 83 using appropriate fixing means (bolts or the like). On the other hand, the stopper member 87 at the front end portion of the spring 84 is fixed to the back surface of the elevating deck 35 using appropriate fixing means (such as a support member and a bolt).

  That is, the elevating deck 35 is mounted on the table 80 via the first and second urging mechanisms 86A and 86B. Thereby, the raising / lowering deck 35 (and the driven slope 36 connected with the raising / lowering deck 35) is comprised so that it can slide to the same direction by the slide movement of the table 80 to the front-back direction. The urging action of the first and second urging mechanisms 86A and 86B will be described later.

  The slide mechanism of the lifting deck 35 includes a drive mechanism that can apply a slide drive force in the front-rear direction to the table 80.

  Specifically, as shown in FIG. 7, the drive mechanism includes a rack and pinion including a motor 89A, a pinion gear (not shown) coupled to the rotation shaft of the motor 89A, and a rack 89B fixed to the table 80. A mechanism.

  Using such a rack and pinion mechanism, the rotational force of the motor 89A is converted into a linear motion force in the front-rear direction of the table 80. As a result, a slide driving force in the front-rear direction is applied to the table 80.

  As shown in FIG. 7, the slide mechanism of the elevating deck 35 includes a pair of fourth and fifth linear guides 92A and 92B each including a table 90 and a rail 91 extending in the front-rear direction.

  The fourth linear guide 92A is disposed in the vicinity of the third frame 65C of the support frame 65, and the rail 91 of the fourth linear guide 92A is attached to the third frame 65C by using an appropriate fixing means (such as a frame). It is fixed. The fifth linear guide 92B is disposed in the vicinity of the fourth frame 65D of the support frame 65, and the rail 91 of the fifth linear guide 92B uses the appropriate fixing means (such as a frame) to form the fourth frame. It is fixed at 65D. Further, the elevating deck 35 is supported by the tables 90 of the fourth and fifth linear guides 92A and 92B.

  With the above configuration, the sliding motion in the front-rear direction of the lifting deck 35 is stably performed while appropriately supporting the lifting deck 35.

  Thus, in the boarding bridge 20 of the present embodiment, the elevating deck 35 can slide in the front-rear direction using the slide mechanism of the elevating deck 35, and the elevating deck 35 is attached to the support frame 65 via the slide mechanism. It is configured so that it can be supported.

<Example of connection operation of boarding bridge 20 to boarding / alighting part 11A of aircraft 11>
Next, an example of the connection operation of the boarding bridge 20 of this embodiment to the boarding / alighting part 11A of the aircraft 11 will be described.

  FIGS. 8 and 9 are diagrams used for explaining an example of the operation of connecting the boarding bridge to the boarding / exiting portion of the aircraft according to the embodiment of the present invention. FIG. 8 illustrates a state in which the elevating deck 35 is being connected to the boarding / exiting part 11A of the aircraft 11, and FIG. 9 illustrates a state when the elevating deck 35 is completely connected to the boarding / exiting part 11A of the aircraft 11. Yes.

  The connecting operation of the boarding bridge 20 to the boarding / alighting part 11A of the aircraft 11 according to the present embodiment is performed as follows.

  First, the cab 26 (fixed passage 32) is turned around the vertical axis 26A. Then, the adjustment passage 33 simultaneously swings left and right.

  Next, the drive column is moved to bring the boarding bridge 20 closer to the aircraft 11 so that the bumper 40 of the boarding bridge 20 contacts the aircraft 11. At this time, when the edge of the floor of the elevating deck 35 and the edge of the floor 11B of the boarding / alighting part 11A of the aircraft 11 are not parallel to each other, the two can be made parallel using the inclined floor 34. .

  At this stage, the elevator deck 35 of the boarding bridge 20 is located below the floor of the boarding / alighting part 11A, so that the door of the boarding / alighting part 11A of the aircraft 11 can be opened.

  After the door of the boarding / alighting part 11A of the aircraft 11 is opened, as shown in FIGS. 8 and 9, the elevating deck 35 is brought to the same height as the floor part 11B of the boarding / alighting part 11A of the aircraft 11 by the elevating mechanism of the elevating deck 35. While moving (raising), the bumper 51 made of synthetic rubber is applied to the floor portion 11B of the boarding / alighting portion 11A of the aircraft 11 by the slide mechanism of the elevating deck 35.

  As shown in FIG. 3, the lifting deck 35 includes a bumper 51, and the bumper 51 is attached over the entire width direction 300 of the front end portion of the lifting deck 35. For this reason, it is possible to mitigate an impact when the lifting deck 35 contacts the boarding / alighting portion 11 </ b> A of the aircraft 11 using the bumper 51. At this time, as the elevating deck 35 moves up and down, the inclination angle φ of the driven slope 36 automatically changes, and the rear end portion of the driven slope 36 moves on the inclined floor 34. Further, as the elevating deck 35 moves in the front-rear direction, the rear end portion of the driven slope 36 moves on the inclined floor 34.

  Next, the structure near the elevating passage 21 will be described in detail with reference to the drawings. FIG. 10 is a plan view showing details of the elevating passage 21 and its peripheral part.

  On both the left and right sides of the lifting / lowering passage 21, plate-like guard plates (protective members) 101A and 101B configured to be able to advance above the passage surface of the lifting / lowering passage 21 are housed. Guard covers 131A and 131B are provided for covering the lid. As soon as the elevating deck 35 starts to rise, the guard covers 131A and 131B are opened upward, and the guard plates 101A and 101B are raised from the opened state. Further, when the elevating deck 35 is lowered from the raised state, the guard plates 101A and 101B are lowered immediately before the lowering is finished, and the guard covers 131A and 131B are closed to return to the original state.

  The two left and right guard plates 101A, 101B and the respective driving mechanisms have a symmetrical structure, and the two right and left guard covers 131A, 131B and the respective driving mechanisms have a laterally symmetrical structure. The guard plate 101A and the guard cover 131A will be described, and the description of the other guard plate 101B and the guard cover 131B will be omitted.

<Guard plate lifting mechanism>
Next, the lifting mechanism (first coupling mechanism) for the guard plate will be described in detail.

  FIG. 11A is a diagram showing a configuration example of the lifting mechanism for the guard plate 101A as viewed in the direction of the line AA in FIG. 10, and FIG. 11B is a diagram showing the CC in FIG. It is a figure which shows one structural example of the raising / lowering mechanism of 101 A of guard plates which looked at the line.

  The support plate 102 is fixed to the side plate 36A of the driven slope 36 using appropriate fixing means (bolts or the like; not shown). On the support plate 102, the rails 105, 108 of the linear guides 106, 109 are fixed to the front portion and the rear portion thereof so as to be parallel to each other and to extend in a direction perpendicular to the main surface of the driven slope 36. The two tables 103 and 104 of the linear guide 106 and the table 107 of the linear guide 109 are fixed at appropriate positions on the guard plate 101A, respectively. Thus, the guard plate 101A is attached to be slidable in the vertical direction with respect to the main surface of the driven slope 36. In addition, an action portion 110 having a groove formed in the front-rear direction is fixed at an appropriate position at a substantially central portion of the guard plate 101A.

  Further, a T-shaped member 111 in which the second member 111B is fixed to the first member 111A is connected to the support plate 102 via a fifth rotation fulcrum 113. That is, the T-shaped member 111 is attached to the support plate 102 so as to be rotatable about the fifth rotation fulcrum 113. One end portion of the first member 111A of the T-shaped member 111 is slidably attached to a groove formed in the front-rear direction of the action portion 110 via the cam follower 112. A roller 114 is attached to the other end of the first member 111A.

  In addition, a restriction plate 118 that contacts the roller 114 when the guard plate 101A is in the housed state is fixed to the connection frame 69 using appropriate fixing means (such as a support member and a bolt).

  Further, one end of the urging means 117 is connected to the tip of the second member 111B of the T-shaped member 111 via the sixth rotation fulcrum 115, and the other end of the urging means 117 is connected via the seventh rotation fulcrum 116. Are connected to predetermined positions of the support plate 102. That is, one end of the urging means 117 is pivotally attached to the tip of the second member 111B, and the other end of the urging means 117 is pivotally attached to a predetermined portion of the support plate 102. The urging means 117 is urged in a direction in which the urging means 117 extends, and is constituted by a gas spring, for example. Here, the urging means 117 applies a force to the T-shaped member 111 to rotate counterclockwise in FIG. 11A around the fifth rotation fulcrum 113. In the state shown in (a), the restriction plate 118 prevents the T-shaped member 111 from rotating.

  As described above, when the elevating deck 35 starts to rise, and accordingly the front of the driven slope 36 starts to rise, the support plate 102 fixed to the driven slope 36 also starts to rise. Then, the T-shaped member 111 starts to turn counterclockwise in FIG. 11A around the fifth rotation fulcrum 113 while pressing the roller 114 against the regulating plate 118 by the urging means 117, and the T-shaped member The cam follower 112 at the rear end of 111 moves (rotates) upward, whereby the action part 110 connected to the cam follower 112 moves upward. At this time, the guard plate 101A to which the action part 110 is fixed moves upward while being guided by the linear guides 106 and 109, and the upper part of the guard plate 101A becomes higher (projects) than the main surface of the driven slope 36. .

  FIG. 12 is a diagram illustrating an example of a state when the guard plate 101A protrudes most.

  When the elevating deck 35 is raised, the front of the driven slope 36 is raised accordingly, and the driven slope 36 is inclined as shown in FIG. 12, for example.

  As described above, when the T-shaped member 111 rotates counterclockwise around the fifth rotation fulcrum 113 and the action part 110 moves upward and contacts the support plate 102 as shown in FIG. The rotation of the T-shaped member 111 is stopped. At this time, the upper portion of the guard plate 101A protrudes upward from the main surface of the driven slope 36 (completely protruded state). Further, when the elevating deck 35 is raised, the roller 114 is separated from the restricting plate 118 while the fully protruding state is maintained, and the front of the driven slope 36 is further lifted. The state at this time is shown in FIG.

  A support member 36B for supporting the rear portion of the driven slope 36 is attached to the lower surfaces of the left and right sides of the rear portion of the driven slope 36, and a roller 36C running on the rail 34B is rotatable at the rear end of the support member 36B. Is attached. The rail 34 </ b> B is disposed below the inclined floor 34 so as to extend in the front-rear direction in parallel with the main surface of the inclined floor 34. The rail 34B is fixed to the inclined floor 34 using appropriate fixing means (a support member, a bolt, etc .; not shown). That is, the front end of the driven slope 36 is rotatably attached to the lifting deck 35, and the rear portion of the driven slope 36 is supported by the roller 36C so as to be movable in the front-rear direction on the rail 34B. Thus, the driven slope 36 is configured such that the rear end portion 36e is movable in the front-rear direction (passing direction 200) along the main surface of the inclined floor 34.

  Here, in FIG. 11A, when a straight line that passes through the trailing edge of the driven slope 36 and is perpendicular to the main surface of the inclined floor 34 is considered, the center of the roller 36C is located slightly rearward of the straight line. It is configured to do. With this configuration, when the elevating deck 35 is raised and the driven slope 36 is inclined, the trailing edge of the driven slope 36 is not pressed against the inclined floor 34, and the trailing edge of the driven slope 36 is A very small gap is formed between the inclined floor 34 and the inclined floor 34. This gap is configured to be extremely small so that there is no substantial step between the rear end edge of the driven slope 36 and the inclined floor 34.

  As a result, when the lifting deck 35 moves up and down and moves in the front-rear direction after being lifted, the rear end portion 36e of the driven slope 36 has a very small gap between the main surface of the inclined floor 34 and the main surface. To move forward and backward. Therefore, as shown in the partial view 6A of FIG. 6, it is possible to prevent the main surface of the inclined floor 34 from being damaged as compared with the case where the rear end portion of the driven slope 36 moves while sliding on the inclined floor 34.

  When the elevating deck 35 moves forward from the state of FIG. 12, the guard plate 101 </ b> A moves forward together with the driven slope 36 while maintaining the inclined state as shown in FIG. 12.

  Further, when returning from the state of FIG. 12 to the state of FIG. 11A, the elevating deck 35 is lowered. At this time, the inclination angle of the guard plate 101A gradually decreases along with the driven slope 36 while the elevating deck 35 is lowered. Then, after the roller 114 attached to the T-shaped member 111 comes into contact with the regulating plate 118, the T-shaped member 111 rotates clockwise by the descending of the driven slope 36, whereby the guard plate 101A is driven. It descends with respect to the slope 36. At the end of the lowering of the lifting deck 35, the state shown in FIG.

  The lifting mechanism for the right guard plate 101B has the same configuration, and the left and right guard plates 101A and 101B are configured to perform the same operation at the same time.

  Here, the guard plates 101A and 101B are configured to operate in conjunction with the lifting operation of the lifting passage 21 (the operation of the driven slope 36), but the guard plates 101A and 101B are operated independently. A drive device dedicated to the guard plate may be separately provided. However, according to the above-described configuration, the drive device dedicated to the guard plate can be omitted.

<Guard cover opening and closing mechanism>
Next, the opening / closing mechanism (second coupling mechanism) of the guard cover (lid) will be described in detail.

  As shown in FIG. 10, the guard cover 131 </ b> A is configured by a hinge that extends long along the left side portion of the elevating passage 21. Similarly, the guard cover 131 </ b> B is a hinge that extends long along the right side portion of the elevating passage 21. It consists of

  FIGS. 13A and 13B are diagrams showing a configuration example of the opening and closing mechanism of the guard cover 131A as viewed in the direction of the line BB in FIG. 10, and FIG. 13A shows a state in which the guard cover 131A is closed. FIG. 13B shows a state in which the guard cover 131A is opened. FIG. 14A is a diagram showing a configuration example of the opening / closing mechanism of the guard cover 131A as viewed in the direction of the line DD in FIG. 13A, and FIG. 14B is a diagram showing the configuration of FIG. It is a figure which shows the example of 1 structure of the opening / closing mechanism of the guard cover 131A seen from the EE line. In FIG. 14A, the roller 137 is not shown.

  A mounting plate 139 is fixed to the housing 40 </ b> A of the bumper 40 provided on the inclined floor 34 with two bolts 142.

  One blade of the two blades of the hinge constituting the guard cover 131A is fixed to the inclined floor 34 by a bolt or the like, and a small rectangular parallelepiped connecting member 132 is fixed to the back surface of the other blade by a bolt or the like. The back surface of the connecting member 132 and the connecting member 134 are connected by a spring hinge 133. The spring hinge 133 is a hinge that incorporates a spring for biasing the guard cover 131A in the opening direction.

  As shown in FIG. 14A, the connecting member 134 has a first surface portion 134a and a second surface portion 134b that are orthogonal to each other, and a spring hinge 133 is attached to the upper portion of the first surface portion 134a. Further, a spring attachment portion 134d is fixed to the upper portion of the second surface portion 134b, and the upper end of the spring 135 is attached thereto. A small elongated hole 134c is provided at the lower portion of the second surface portion 134b, and a spring attachment portion 136a fixed to one end of the L-shaped member 136 is inserted through the elongated hole 134c. The lower end of the spring 135 is inserted into the spring attachment portion 136a. It is attached.

  The corner portion 138 of the L-shaped member 136 is rotatably attached to the attachment plate 139. In addition, one end of the spring 140 is attached to a spring attachment portion 136 b fixed to the other end of the L-shaped member 136. The other end of the spring 140 is attached to a spring attachment portion 139 a fixed to the attachment plate 139.

  In addition, a roller 137 is rotatably attached to the L-shaped member 136 at a predetermined position between the spring attachment portion 136a and the corner portion 138. When the guard cover 131A is closed, the roller 137 is pressed against the bumper 51 of the elevating deck 35 from above as shown in FIG. Further, as shown in FIG. 13B, when the L-shaped member 136 is rotated and the guard cover 131A is opened, the stopper member 141 that prevents further rotation of the L-shaped member 136 is the mounting plate. 139.

  For example, as shown in FIG. 13A, when the elevating deck 35 is in the stowed state (the most lowered state), the roller 137 is pressed from above by the bumper 51 of the elevating deck 35 as described above. When 35 starts to rise, the bumper 51 also rises, so that the L-shaped member 136 is rotated about the corner portion 138 in the direction in which the roller 137 is raised by the pulling force of the spring 140. Then, the connecting member 134 and the spring hinge 133 attached thereto are pushed up, and the guard cover 131A is opened by the biasing force of the spring hinge 133 as shown in FIG. Furthermore, even if the raising / lowering deck 35 rises, the guard cover 131A is maintained in the open state of FIG.

  When the lifting deck 35 is lowered from the raised state, the bumper 51 of the lifting deck 35 is in contact with the roller 137 when the lifting deck 35 is lowered to the position shown in FIG. Further, when the lifting deck 35 is lowered, the L-shaped member 136 is rotated in the direction in which the roller 137 is lowered, whereby the connecting member 134 and the spring hinge 133 are lowered. It becomes a state.

  The opening / closing mechanism of the right guard cover 131B has the same configuration, and the left and right guard covers 131A and 131B are configured to simultaneously perform the same operation.

  That is, when the elevating deck 35 begins to rise from the stored state, the left and right guard covers 131A and 131B begin to open, and the front of the driven slope 36 begins to lift, so the left and right guard plates 101A and 101B also begin to rise. At this time, the left and right guard covers 131A and 131B are configured to open quickly so that the left and right guard covers 131A and 131B do not contact the left and right guard plates 101A and 101B.

  Further, when the elevating deck 35 is lowered from the raised state, the left and right guard plates 101A, 101B begin to close immediately after the elevating deck 35 is lowered after the left and right guard plates 101A, 101B begin to be stored. At this time, the left and right guard covers 131A and 131B are configured to close slowly so that the left and right guard covers 131A and 131B do not contact the left and right guard plates 101A and 101B.

  As described above, the boarding bridge 20 of the present embodiment includes the walking passage 31 and the up-and-down passage 21 that is provided in the plane of the walking passage 31 in a plan view and that can be used for connection with the boarding / alighting portion 11A of the aircraft 11. I have. And when this raising / lowering channel | path 21 goes up, the rear-end part (other than one end part) which is different from the front-end part (one end part, for example, front-end part of the raising / lowering deck 35) connected with the boarding / alighting part 11A For example, the rear end portion 36e) of the driven slope 36 is maintained in a state where there is no substantial step between the walking passage 31 (inclined floor 34) and the front end portion (lifting deck 35) side rises. Between the front end portion and the rear end portion, the front portion (front end portion side) includes a slope that is higher than the rear portion (rear end portion side) and is configured to form a passage without a stepped step. ing.

  Here, as one example, the elevating passage 21 has an elevating deck 35 used for connection with the boarding / alighting portion 11A of the aircraft 11, an elevating mechanism for elevating the elevating deck 35, and a fixed end portion of which is connected to the third connecting hinge 50. And a free slope (rear end 36e) having a driven slope 36 that is configured to be movable along the main surface of the inclined floor 34 in the passage direction 200. As the elevating deck 35 moves, the driven slope 36 rotates around the axis of the third connecting hinge 50, and the rear end 36e moves in the passage direction 200 along the main surface of the inclined floor 34. A driven slope 36 forms a continuous ramp between the elevating deck 35 and the walking passage 31 (inclined floor 34).

  With the above configuration, since there is no step between the floor portion 11B of the boarding / alighting portion 11A and the lifting / lowering passage 21 (for example, the lifting / lowering deck 35) of the boarding bridge, a continuous passage can be formed between them.

  Therefore, in the boarding bridge 20 of the present embodiment, a step with the boarding / alighting part 11A of the aircraft 11 can be eliminated, and for example, every time a passenger in a wheelchair gets on and off the aircraft 11, the elevator passage 21 (elevating deck) Since it is not necessary to go up and down 35), the passenger can get on and off the aircraft 11 smoothly.

  In particular, in the boarding bridge 20 of the present embodiment, the height of the lifting deck 35 can be adjusted by a simple lifting movement of the lifting deck 35, so that the floor of the lifting deck 35 is maintained substantially horizontal without being inclined. can do. For this reason, there exists an advantage that alignment with the raising / lowering deck 35 and the floor part 11B of the boarding / alighting part 11A is easy.

  However, the elevating passage 21 is not limited to the configuration including the elevating deck 35 and the driven slope 36. For example, when the elevating passage 21 rises, the other end separated from one end (front end) connected to the getting-on / off portion 11A. By maintaining the state where the part (rear end part) is not substantially stepped with the walking passage 31 (inclined floor 34) and the one end part rises, an inclined path is formed between the one end part and the other end part. It may be configured to.

  Moreover, in the boarding bridge 20 of this embodiment, the raising / lowering deck 35 is provided with the slide mechanism which slides in a person's passage direction. And the raising / lowering deck 35 moves to the same height as the floor part 11B of the boarding / alighting part 11A by the raising / lowering mechanism, and contacts the boarding / alighting part 11A by the slide mechanism.

  With the above configuration, even if a slight gap is generated between the lifting deck 35 and the boarding / alighting part 11A of the aircraft 11, the sliding mechanism can slide to the position where the lifting deck 35 contacts the boarding / alighting part 11A. Such a gap can also be eliminated.

  Further, the boarding bridge 20 of the present embodiment has a plate-like shape as a protective member that protrudes upward from the passage surface of the lifting / lowering passage 21 along the left and right sides of the lifting / lowering passage 21 when the lifting / lowering passage 21 rises. Guard plates 101A and 101B are provided.

  With the above configuration, for example, it is possible to reduce anxiety that a wheelchair may be removed from the lift passage 21 for a passenger in a wheelchair.

  Further, since the guard plates 101A and 101B are configured to operate in conjunction with the lifting / lowering operation of the lifting / lowering passage 21 (the tilting operation of the driven slope 36 accompanying the lifting / lowering operation of the lifting / lowering deck 35), the guard plates 101A and 101B are configured. A dedicated drive device for operating the camera is unnecessary.

  In addition, since guard covers 131A and 131B are provided to cover the upper ends of the gaps between the side portions on both sides of the elevating passage 21 serving as the entrances and exits of the guard plates 101A and 101B and the inclined floor 34, dust or the like is put into the gaps. Intrusion can be prevented. In addition, since the guard covers 131A and 131B are also configured to operate in conjunction with the lifting operation of the lifting passage 21 (the lifting operation of the lifting deck 35), a dedicated drive device for operating the guard covers 131A and 131B is provided. It is unnecessary.

  Further, in the boarding bridge 20 of the present embodiment, the walking passage 31 includes an inclined floor 34 that adjusts the inclination in the width direction of the elevating deck 35 and the driven slope 36, an inclination mechanism that can incline the inclined floor 34 in the width direction 300, and When the inclined floor 34 is viewed in plan, the elevating deck 35 and the driven slope 36 are attached in the plane of the inclined floor 34.

  By the above, when the edge of the floor of the raising / lowering deck 35 and the edge of the floor part 11B of the boarding / alighting part 11A of the aircraft 11 are not parallel, the two can be paralleled by using the inclined floor 34. . In particular, in the boarding bridge 20 of the present embodiment, the parallel adjustment between the elevating deck 35 and the getting-on / off part 11A by the inclined floor 34 can be performed even while the drive column of the boarding bridge 20 is being moved. Can be connected efficiently.

  Further, in the boarding bridge 20 of the present embodiment, the first and second urging mechanisms 86A and 86B of the slide mechanism are used to further lift and lower from the position where the bumper 51 of the lifting deck 35 abuts the boarding / alighting portion 11A. When the table 80 is slid so as to press the deck 35 against the boarding / alighting portion 11A, an urging force of the elevating deck 35 (bumper 51) to the aircraft 11 is generated. That is, when the table 80 is slid so as to press the elevating deck 35 against the loading / unloading portion 11A from the contact position, the stopper member 88 resists the reaction force of the spring 84 as shown in FIGS. Move forward along axis 85. Then, the spring 84 is compressed by the stopper members 87 and 88, and the urging force of the elevating deck 35 (bumper 51) to the aircraft 11 is generated based on the reaction force of the spring 84 generated thereby.

  With the above configuration, in the boarding bridge 20 of the present embodiment, when the clearance between the elevator deck 35 (bumper 51) and the boarding / alighting part 11A (outer wall) of the aircraft 11 varies due to the ups and downs of the aircraft 11 as passengers get on and off. Even so, by the action of the first and second urging mechanisms 86A, 86B of the slide mechanism, the elevating deck 35 (bumper 51) can be moved in the front-rear direction in accordance with the ups and downs of the aircraft 11, Generation | occurrence | production of the said clearance gap can be prevented appropriately.

  From the foregoing description, many modifications and other embodiments of the present invention are obvious to one skilled in the art. Accordingly, the foregoing description is to be construed as illustrative only and is provided for the purpose of teaching those skilled in the art the preferred mode of carrying out the invention. The details of the structure and / or function may be substantially changed without departing from the spirit of the invention.

  INDUSTRIAL APPLICABILITY The present invention is useful as a boarding bridge that can reduce anxiety felt by passengers, for example, passengers in wheelchairs, and can smoothly get on and off a moving body.
