Description

  The present invention relates to a boarding bridge used for passengers getting on and off an aircraft or a ship.

  The boarding bridge is, for example, a tunnel-like passage that connects an airport terminal building and an aircraft, and allows passengers to get on and off directly between the terminal building and the aircraft. The boarding bridge includes a plurality of passage bodies fitted in a telescopic manner, and these passage bodies expand and contract by moving relative to each other in the longitudinal direction. This makes it possible to cope with various intervals that occur between the terminal building and the aircraft.

  Since the passage body is fitted in a telescopic manner, a step is generated in the adjacent portion of the adjacent passage body in the conventional boarding bridge. In Patent Document 1 below, a technique is disclosed in which the passage portion of the outer passage body moves between a predetermined passage position and an outer passage position below the predetermined passage position in order to eliminate the step difference of the passage. ing. Accordingly, the length of the entire passage body in the longitudinal direction can be changed, and the passage portion of the outer passage body is set to the same height as the passage portion of the inner passage body, so that the step of the passage is eliminated.

Japanese Patent No. 4700643 Japanese Patent No. 5073109

Further, in Patent Document 2, as in Patent Document 1, the passage portion of the outer passage body moves between a predetermined passage position and a passage outside position below the predetermined passage position, thereby adjacent to each other. A technique for eliminating a step difference in a passage in an adjacent portion of a matching passage body is disclosed.
On the other hand, in Patent Document 2, the support rod is urged in a direction extending from the plate-like floor member by an urging spring and can be contracted in the reverse direction. It expands and contracts with respect to the wall surface of the guide rail fixed to each of the first tunnel) and the outer tunnel (second tunnel). As a result, each plate-like floor member has a complicated structure.

  Moreover, in patent document 2, a support rod is extended from the edge side of the plate-shaped floor member which comprises a movable channel | path, and a support rod moves along the guide rail provided in the inner side tunnel. That is, with the movement of the outer tunnel, the support rod provided on each plate-like floor member slides on the guide rail. Therefore, it is necessary to reduce the friction between the support rod and the guide rail, and in operation, the support rod must be provided with a rotatable roller.

  Furthermore, in Patent Document 2, the plate-like floor member is supported on the slide rail by the support rod at the central portion of the short side of the plate-like floor member, but the plate-like floor member is around the axis of the support rod. Since it rotates, it is unstable and it is difficult for the passersby in the boarding bridge to walk.

  The present invention has been made in view of such circumstances, and has a simple structure and can stably move a passage portion between a predetermined passage position and a lower outside passage position. The purpose is to provide a bridge.

In order to solve the above problems, the boarding bridge of the present invention employs the following means.
That is, the boarding bridge according to the present invention is a boarding bridge in which a plurality of cylindrical passage bodies are fitted in a nesting manner and move relative to each other in the longitudinal direction to expand and contract. A passage portion that is provided in one first passage body and moves between a passage position set at a predetermined height position and an outer passage position located below the passage position; and A plurality of the first passage bodies are provided along the longitudinal direction of the first passage body so as to be installed at the passage position, can support the width direction end of the passage portion, and are movable in the width direction of the passage portion. And a protrusion that moves the support to the outside in the width direction of the passage. The protrusion is separated from the support of the support by the protrusion and the position outside the passage. Between the adjoining said And a transition rails fixed to the second passage of the other of the body.

According to this configuration, the support portion is provided along the longitudinal direction of the first passage body, and the width direction end of the passage portion is disposed so that the passage portion is installed at the passage position set at the predetermined height position. Support the part. The support portion is movable in the width direction of the passage portion, and the protrusion of the transition rail moves the support portion to the outside in the width direction of the passage portion. And a passage part remove | deviates from a support of a support part by a support part moving to the width direction outer side of a channel | path part.
In addition, when the support portion moves to the outer side in the width direction of the passage portion, the passage portion rising along the transition rail is moved from the transition rail to the support portion, or the passage portion placed on the support portion is moved. A space is formed in which the passage portion can be lowered along the transition rail by moving from the support portion to the transition rail.
As a result, when the first passage body relatively moves in the longitudinal direction with respect to the second passage body, the protrusions of the transition rail fixed to the second passage body sequentially support the support portions provided on the first passage body. Move to the outside in the width direction of the passage. Therefore, by moving the passage portion from the position outside the passage to the passage position, the area in which the passage portion can pass in the first passage body becomes longer, and conversely, the passage portion moves from the passage position to the position outside the passage. The passable area of the passage portion in the first passage body is shortened.

  Further, the boarding bridge according to the present invention is a boarding bridge in which a plurality of cylindrical passage bodies are fitted in a nested manner, and move relative to each other in the longitudinal direction to expand and contract. A passage portion that is provided in one first passage body and moves between a passage position set at a predetermined height position and an outer passage position located below the passage position; and A plurality of support portions provided along the longitudinal direction of the first passage body so as to be installed at the passage position, and supporting a width direction end portion of the passage portion; It is placed on a lower surface of one passage body or a member fixed to the first passage body and is installed at a position outside the passage.

According to this configuration, the support portion is provided along the longitudinal direction of the first passage body, and the width direction end of the passage portion is disposed so that the passage portion is installed at the passage position set at the predetermined height position. Support the part. When the passage portion moves from the position outside the passage to the passage position, the area of the first passage body through which the passage portion can pass becomes longer, and conversely, the passage portion moves from the passage position to the position outside the passage. The passage area of the passage portion in the passage body is shortened.
The passage portion installed at the position outside the passage is placed on a lower surface of the first passage body or a member fixed to the first passage body. Accordingly, since the passage portion at the position outside the passage does not come into contact with the second passage body, even if the first passage body and the second passage body move relative to each other when the boarding bridge is expanded or contracted, the passage at the position outside the passage The part does not slide in the longitudinal direction in relation to the second passage body.

  Further, the boarding bridge according to the present invention is a boarding bridge in which a plurality of cylindrical passage bodies are fitted in a nested manner, and move relative to each other in the longitudinal direction to expand and contract. A passage portion that is provided in one first passage body and moves between a passage position set at a predetermined height position and an outer passage position located below the passage position; and A plurality of support portions provided along the longitudinal direction of the first passage body so as to be installed at the passage position, and supporting end portions in the width direction of the passage portion; A plate-like member divided into a plurality of directions, and a first protruding portion that is formed so as to protrude from the plate-like member and supported by the support portion other than an intermediate portion on one side of the plate-like member.

According to this configuration, the support portion is provided along the longitudinal direction of the first passage body, and the width direction end of the passage portion is disposed so that the passage portion is installed at the passage position set at the predetermined height position. Support the part. When the passage portion moves from the position outside the passage to the passage position, the area of the first passage body through which the passage portion can pass becomes longer, and conversely, the passage portion moves from the passage position to the position outside the passage. The passage area of the passage portion in the passage body is shortened.
The passage portion can be bent because the plate-like members divided into a plurality of portions in the longitudinal direction are connected. Moreover, the 1st protrusion part for supporting a channel | path part to a support part is protruded and formed from the plate-shaped member, and is provided except for the intermediate part of one side of a plate-shaped member. Therefore, since the plate-like member of the passage portion is supported by other than the middle portion of one side (for example, the end portion or the vicinity of the end portion), the plate-like member is prevented from rotating around the axis of the first protruding portion by walking. it can. As a result, since the plate-shaped member is stabilized, it is easy for a pedestrian to walk on the passage.

  The said invention WHEREIN: You may further have the 2nd protrusion part which protrudes from the said plate-shaped member in the intermediate part of the one side of the said plate-shaped member, and is supported by the said support part.

  According to this structure, the 2nd protrusion part for supporting a channel | path part to a support part protrudes from a plate-shaped member in the intermediate part of one side of a plate-shaped member, and is formed. Further, the plate-like member of the passage portion is supported by the first projecting portion at the end portion or in the vicinity of the end portion other than the intermediate portion on one side. Therefore, even when the second protruding portion is provided at an intermediate portion of one side of the plate-like member, the plate-like member can be prevented from rotating around the axis of the protruding portion by walking.

  Further, the boarding bridge according to the present invention is a boarding bridge in which a plurality of cylindrical passage bodies are fitted in a nested manner, and move relative to each other in the longitudinal direction to expand and contract. A passage portion that is provided in one first passage body and moves between a passage position set at a predetermined height position and an outer passage position located below the passage position; and A plurality of support portions provided along the longitudinal direction of the first passage body so as to be installed at the passage position, and supporting one end in the width direction of the passage portion, and one end fixed to the first passage body And a tension portion whose other end is fixed to the end portion in the longitudinal direction of the passage portion.

According to this configuration, the support portion is provided along the longitudinal direction of the first passage body, and the width direction end of the passage portion is disposed so that the passage portion is installed at the passage position set at the predetermined height position. Support the part. When the passage portion moves from the position outside the passage to the passage position, the area of the first passage body through which the passage portion can pass becomes longer, and conversely, the passage portion moves from the passage position to the position outside the passage. The passage area of the passage portion in the passage body is shortened.
One end of the tension portion is fixed to the first passage body, the other end is fixed to the end portion in the longitudinal direction of the passage portion, and the passage portion is pulled so that tension is applied to the passage portion. Since the tension portion has one end fixed to the first passage body, even when the passage portion moves between the passage position and the outside passage position, the connection point between the tension portion and the first passage body and the passage portion The distance between the connection points with the longitudinal ends is substantially constant. Therefore, the tension portion can have a simple structure as compared with the case where one end of the tension portion is fixed to the second passage body.

  According to the present invention, the passage portion can be stably moved between a predetermined passage position and a lower outside passage position with a simple structure.

Embodiments according to the present invention will be described below with reference to the drawings.
[First Embodiment]
Hereinafter, the boarding bridge 1 which concerns on 1st Embodiment of this invention is demonstrated using FIGS.
The boarding bridge 1 forms a passenger passage between the airport terminal building and the aircraft 10 to connect the terminal building and the aircraft 10 so that passengers can get on and off directly.
The boarding bridge 1 includes a rotander 2 fixed to a fixed bridge 11 leading to a terminal building, and a proximal end tunnel 3 (passage body, first passage) connected to the rotander 2 so as to be rotatable in a horizontal direction and a vertical direction. A two-passage body) and a distal-end tunnel 4 (passage body, first passage body) which is telescopically fitted and moved outside the proximal-end tunnel 3 on the distal-end side (aircraft 10 side) of the proximal-end tunnel 3 The head 5 is fixed to the tip of the tip tunnel 4.

  A fixed leg 6 is fixed to the ground below the rotander 2. A movable leg 7 is provided on the distal end side in the longitudinal direction of the distal end tunnel 4. The boarding bridge 1 is supported by a fixed leg 6 and a movable leg 7.

  The proximal end tunnel 3 and the distal end tunnel 4 each have a hollow long rectangular column shape. In the proximal tunnel 3 and the distal tunnel 4, for example, steel structural beams 8 (see FIGS. 3 and 4) are arranged on each side of the quadrangular column, and the structural beams 8 are connected to both side surfaces and upper and lower surfaces. An iron plate panel 9 (see FIGS. 3 and 4) is attached and formed into a cylindrical shape. The panel 9 may have a wall made of a material such as aluminum, synthetic resin, or transparent material (synthetic resin, glass, etc.) on the outer surface of the steel structure.

  The cross-sectional area of the hollow portion of the front end tunnel 4 is larger than the cross-sectional area of the base end tunnel 3. The distal end tunnel 4 moves along the outer peripheral surface of the proximal end tunnel 3. A wheel portion 39 is provided on the lower surface of the proximal end tunnel 3, and the distal end portion of the proximal end tunnel 3 is supported by the distal end tunnel 4 via the wheel portion 39. The wheel portion 39 moves on the structural beam 8 of the tip tunnel 4. The tip tunnel 4 is moved in the longitudinal direction N when the movable leg 7 is driven and moved, and the length of the entire boarding bridge 1 is expanded and contracted. Since the boarding bridge 1 expands and contracts in this way, it can cope with various intervals generated between the rotander 2 fixed to the terminal building and the aircraft 10 depending on the parking position of the aircraft 10.

  The head 5 is connected to the entrance of the aircraft 10 at the tip side. Inside the head 5 is provided an operation unit (not shown) for driving and operating the movable leg 7 of the boarding bridge 1.

Inside the boarding bridge 1, a passage through which passengers pass is constituted by fixed passages 12 and 13, an open / close passage portion 17, a passable area 15, and a fixed passage 16 from the rotander 2 toward the head 5. The upper surfaces of the fixed passages 12 and 13, the open / close passage portion 17, the passable area 15, and the fixed passage 16 are at a substantially constant height position (passage height H ₁ ). Thereby, the level | step difference which arises inside the boarding bridge 1 can be suppressed few.
The fixed passage 12 is provided inside the rotander 2, and the fixed passage 13 is provided inside the proximal end tunnel 3 over substantially the entire length thereof.

A movable passage portion 14 (passage portion) is provided inside the front end tunnel 4. The movable passage portion 14 is positioned at the passage height H ₁ on the distal end side of the distal end tunnel 4 and is fixed to the rear end of the fixed passage 16 of the head 5. The movable passage portion 14 is positioned at a passage outer height H ₂ lower than the passage height H ₁ on the rear end side of the tip tunnel 4 and is fixed to the tip tunnel 4 via the tension portion 36 and the anchor portion 35. The Here, the passage height H ₁ and the passage outer height H ₂ are heights from the lower surface of the front end tunnel 4 to the upper surface of the movable passage portion 14.

  As shown in FIGS. 10 and 11, the anchor portion 35 is a beam-like member, for example, and both ends are fixed to the structural beam 8 of the tip tunnel 4. The tension part 36 includes a tension spring 37 and an adjustment part 38, for example. The tension portion 36 has one end fixed to the anchor portion 35 and the other end fixed to the longitudinal end portion of the movable passage portion 14. The tension spring 37 pulls the movable passage portion 14 so that tension is applied to the movable passage portion 14. Since the tension spring 37 has elasticity, a change in force applied to the tension portion 36 can be reduced as compared with the case where the tension spring 37 is not used. The adjustment unit 38 adjusts the distance between the anchor unit 35 and the movable passage unit 14 so that an appropriate tension is applied to the movable passage unit 14. The adjustment part 38 is a turnbuckle, for example.

Tension unit 36, since one end of which is fixed to the distal end tunnel 4 via the anchor portion 35, even when the movable passage portion 14 moves between the passage height H ₁ and the outer-conduit height H _2, tension The distance between the connection point of the part 36 with the tip tunnel 4 (connection point with the anchor part 35) and the connection point of the longitudinal end part of the movable passage part 14 is substantially constant. Therefore, the tension part 36 can have a simple structure as compared with the case where one end of the tension part 36 is fixed to the proximal end tunnel 3.

Movable passage 14 located in the passage height H ₁ is a passable area 15 passenger traffic. As the distal tunnel 4 moves, the movable passage portion 14 moves to the passage height H ₁ in the vicinity of the distal end side of the proximal end tunnel 3 or to the passage outer height H ₂ . Thereby, the length of the passable area 15 expands and contracts.

The fixed passage 16 is provided inside the head 5. The distal end of the movable passage portion 14 of the distal end tunnel 4 is fixed to the rear end of the fixed passage 16 of the head 5.
The open / close passage portion 17 is provided at the distal end of the proximal end tunnel 3, that is, at the distal end tunnel 4 side. The opening / closing passage portion 17 swings up and down about an axis extending in the width direction of the passage of the boarding bridge 1 by a driving device (not shown), and the tip end side can contact the movable passage portion 14. . The open / close passage portion 17 connects the fixed passage 13 of the proximal end tunnel 3 to the accessible area 15 of the distal end tunnel 47 and forms a continuous passage inside the boarding bridge 1.

Next, the movable passage portion 14 will be described with reference to FIGS.
The movable passage portion 14 includes a step 18 having a plate-like portion and a support portion 22 such as a slide plate 23 that supports the step 18.
One step 18 is a member that is long in the width direction of the passage and short in the depth direction, and the movable passage portion 14 is configured by connecting a plurality of steps 18. The adjacent step 18 is connected so as to be relatively rotatable at the connecting portion, so that the movable passage portion 14 can be bent. As a result, the movable passage portion 14 can move between a passage height H ₁ set at a predetermined height position and a passage outside height H ₂ positioned below the passage height H ₁ .

  Step 18 has a projecting portion 19 formed extending from Step 18 at the end in the width direction of the movable passage portion 14. Step 18 is supported on the slide plate 23 or on the transition rail 30 by the protrusion 19.

The support portion 22 includes a slide plate 23, a bracket 24, a coil spring 25, and the like.
As shown in FIGS. 6 and 7, one slide plate 23 has a length in the longitudinal direction corresponding to a plurality of sheets in step 18, and is placed on different brackets 24 at both ends. Yes.
The brackets 24 are provided at equal intervals along the longitudinal direction of the distal end tunnel 4.
The coil spring 25 is a compression spring, and is installed between the slide plate 23 and the inner wall surface of the panel 9 of the front end tunnel 4. The coil springs 25 are installed one by one near the end of the slide plate 23, for example. One slide plate 23 may be provided with a single leaf spring instead of the two coil springs 25.

  The slide plate 23 is movable in the width direction of the movable passage portion 14 on the bracket 24. When the slide plate 23 is pressed by the protrusion 32 formed on the transition rail 30, the slide plate 23 moves toward the outer side of the movable passage portion 14 and is biased by the coil spring 25, so that the slide plate 23 moves toward the movable passage portion 14. Moving.

  The slide plate 23 includes a flat plate 27 on which the protruding portion 19 is placed, a rising plate 28 provided in a direction perpendicular to the flat plate 27, and the like. The rising plate 28 is in contact with the protrusion 32 provided on the transition rail 30.

  A connecting portion 33 is provided at the end of the rising plate 28. The connecting portion 33 is composed of two plate-like members formed so as to sandwich the rising plate 28 of the adjacent slide plate 23 from both sides. Accordingly, since the plurality of slide plates 23 are connected via the connecting portion 33, when one slide plate 23 is moved by the protruding portion 32, the other slide plates 23 can be moved together.

The transition rail 30 includes a rail portion 31 on which the projecting portion 19 of step 18 slides, and a projection portion 32 that presses the rising plate 28 of the slide plate 23.
The transition rail 30 is fixed to the proximal end tunnel 3. Rail portion 31 of the transition rail 30 has an inclined surface connecting between the passage height H ₁ and the outer-conduit height H ₂ of the movable passage 14. The protrusion 32 is formed at substantially the same height as the position where the slide plate 23 is installed.

  When the proximal tunnel 3 moves relative to the distal tunnel 4, the contact position between the protrusion 32 and the slide plate 23 changes. When the slide plate 23 is moved to the outside of the movable passage portion 14 by the protrusion 32, the distance between the slide plate 23 and the step 18 is widened. Further, when the slide plate 23 is moved toward the movable passage portion 14 by the urging force of the coil spring 25, the distance between the slide plate 23 and the step 18 is narrowed.

  Therefore, when the contact position between the protrusion 32 and the slide plate 23 changes, the protruding portion 19 of the step 18 moves onto the slide plate 23 at one end 31 a of the rail portion 31, or the rail portion 31 of the transition rail 30. Or move up. Further, at the other end 31 b of the slide plate 23, the protruding portion 19 of the step 18 moves onto the transition rail 30 or moves to the fixed rail 34 (see FIGS. 2 and 8) of the distal end tunnel 4. Furthermore, when the transition rail 30 relatively moves in the longitudinal direction of the boarding bridge 1, the step 18 located on the transition rail 30 moves in the vertical direction along the inclined surface.

Fixed rail 34 is installed in the tip tunnel 4 at a position where the movable passage 14 is a passage outside the height H _2. Step 18 is mounted on the fixed rail 34, the step 18 is located in the passage outside the height H _2. The step 18 is not placed on the proximal tunnel 3 but on the fixed rail 34 installed in the distal tunnel 4. Accordingly, since the step 18 at the passage outer height H ₂ does not come into contact with the proximal tunnel 3, even if the distal tunnel 4 and the proximal tunnel 3 move relative to each other when the boarding bridge 1 is expanded and contracted, the passage outer height Step 18 at the height H ₂ does not slide in the longitudinal direction in relation to the proximal tunnel 3. Note that the step 18 may be placed directly on the lower surface of the front end tunnel 4 without providing the fixed rail 34 in the front end tunnel 4. Also in this case, the step 18 does not slide in the longitudinal direction in relation to the proximal tunnel 3.
In addition, the present invention is not limited to the above-described example, and sliding in the longitudinal direction of step 18 occurs. However, step 18 may be placed not on the distal end tunnel 4 but on the proximal end tunnel 3.

  At both ends in the longitudinal direction of the slide plate 23, there are support plates 29 protruding outward. The support plate 29 is sandwiched between the fixing portion 26 on the bracket 24. The fixing part 26 is fixed to the bracket 24. Thereby, when a load is applied to the step 18, the fixing portion 26 supports the support plate 29, so that the step 18 can be prevented from falling with the slide plate 23. Note that a gap is provided between the fixed portion 26 and the bracket 24 so that the support plate 29 can slide, and the slide plate 23 can slide on the bracket 24.

Next, the protrusion part 19 provided in step 18 is demonstrated.
As shown in FIGS. 6 and 7, the protruding portion 19 includes, for example, a roller 19 </ b> A. The protrusion 19 supports the weight of the step 18 and the load applied to the step 18.
The position where the roller 19 </ b> A is provided is a connecting portion between adjacent steps 18, and the central axis of the roller 19 </ b> A coincides with the rotation axis of the two steps 18. As described above, since the projecting portion 19 that supports the load is provided at the connecting portion 18A of the two steps 18, the plate-like step 18 is supported at the end portion, so that the step 18 is rotated around the central axis of the roller by walking. Can be prevented from rotating. Therefore, since step 18 is stabilized, it is easy for a pedestrian to walk on the passage.

  In the present embodiment, the central axis that supports the roller 19 </ b> A is connected to the adjacent step 18, and is also used as the pin 19 </ b> B that becomes the rotation axis of the step 18. Unlike the support rod of Patent Document 2, the protrusion 19 of this embodiment does not have a telescopic function. Since the support rod of patent document 2 exhibits an expansion-contraction function, it is difficult to provide in the connection pin to which a load is added. On the other hand, in the present embodiment, even if the roller 19A is attached to the pin 19B that connects the steps 18 to each other, the protrusion 19 does not need to be expanded and contracted, so that no problem occurs.

Hereinafter, modified examples of the protruding portion 19 will be described.
As shown in FIGS. 12 to 15, the position where the roller 19 </ b> A and the pin 19 </ b> B of the protruding portion 19 are provided may be in the vicinity of the connecting portion 18 </ b> A instead of the connecting portion 18 </ b> A of the adjacent step 18. At this time, as shown in FIGS. 12 and 14, the roller 19 </ b> A may be provided at two locations with respect to one side of one step 18, or as shown in FIGS. 14 and 15. 19A may be provided at one place with respect to one side of one step 18. In any case, since the protrusion 19 is provided in the vicinity of the connecting portion 18A, the rotation of the step 18 can be suppressed and stabilized, so that a pedestrian can easily walk on the passage.

  Furthermore, as shown in FIGS. 16 and 17, the protrusion 19 according to another modification is provided with a roller 19A at the center of the short side portion of the step 18 and plate-like portions 19C on both sides of the roller 19A. ing. In this case, the protrusion 19 including the roller 19 </ b> A and the plate-like portion 19 </ b> C is positioned on the transition rail 30 and the slide plate 23 to support the step 18. Thereby, even if the step 18 rotates around the central axis of the roller 19 </ b> A, the plate-shaped portion 19 </ b> C abuts against the slide plate 23, thereby suppressing the range where the step 18 is inclined. Then, by forming the ground contact surface of the roller 19A and the lower surface of Step 18 so as to be within the same surface or substantially the same surface, the rotation of Step 18 can be further suppressed.

  The roller 19A of the protrusion 19 described above can smoothly move the step 18 on the transition rail 30. On the other hand, when the friction coefficient can be reduced depending on the shape and material of the step 18 and the transition rail 30, as shown in FIGS. In this case, the plate-like portion 19 </ b> C is positioned on the transition rail 30 or the slide plate 23 and supports the step 18. In this configuration, since there is no roller in the first place, the step 18 does not rotate but stabilizes.

Next, the operation of the boarding bridge 1 according to this embodiment described above will be described.
The boarding bridge 1 stands by in a state in which the distal end tunnel 4 is largely fitted with the proximal end tunnel 3 as shown by a two-dot chain line in FIG.
When the aircraft 10 arrives at a predetermined position, the movable leg 7 is operated, and the tip tunnel 4 moves toward the aircraft 10. That is, the entire boarding bridge 1 is extended.

When the tip tunnel 4 moves toward the aircraft 10, the step 18 placed at the passage outside height H ₂ moves from the other end portion 30 b of the transition rail 30 to the rail portion 31 of the transition rail 30, and the transition rail 30. The upper step 18 rises to the passage height H ₁ along the slope of the rail portion 31 of the transition rail 30. At the passage height H ₁ , the slide plate 23 that is in contact with the protrusion 32 moves outward in the width direction of the passage by the protrusion 32, and the slide plate 23 that is not in contact with the protrusion 32 is also interlocked by the connecting portion 33. Move. Thereby, since the space | interval of the slide plate 23 and step 18 spreads, the space which the protrusion part 19 of step 18 can raise along the transition rail 30 arises.

When the tip tunnel 4 moves toward the aircraft 10, the protruding portion 19 of the step 18 placed on the transition rail 30 at the passage height H ₁ is moved from the one end 31 a of the transition rail 30 to the slide plate 23. Move up. Thereby, since the rear end side of the steps 18 of the movable passage 14 is sequentially moved to the passageway height H _1, the length in the longitudinal direction N of the passable region 15, a distance distal tunnel 4 is moved longer Become.
At this time, the opening / closing passage portion 17 is retracted upward by the drive device so that the opening / closing passage portion 17 is not damaged by rubbing the step 18 in which the opening / closing passage portion 17 moves.

When the head 5 is connected to the aircraft 10, the open / close passage portion 17 is lowered to make the passable area 15 and the fixed passage 13 continuous.
Since the movable passage portion 14 is pulled with an appropriate tension by the tension portion 36, the tension in the longitudinal direction N also acts on the step 18 located in the passable area 15 to form a stable passage.

  When the passage of the passerby is completed, the head 5 is detached from the aircraft 10 and the tip tunnel 4 is moved to the rotander 2 side. At this time, the open / close passage portion 17 is retracted in the same manner as described above.

When the tip tunnel 4 moves toward the rotander 2, the protrusion 19 of the step 18 placed on the slide plate 23 moves from the slide plate 23 to one end 31 a of the transition rail 30. At the passage height H ₁ , the slide plate 23 that is in contact with the protrusion 32 moves outward in the width direction of the passage by the protrusion 32, and the slide plate 23 that is not in contact with the protrusion 32 is also interlocked by the connecting portion 33. Move. Thereby, since the space | interval of the slide plate 23 and step 18 spreads, the space which the protrusion part 19 of step 18 can descend | fall along the transition rail 30 arises.

When the tip tunnel 4 moves toward the rotander 2, the step 18 on the transition rail 30 descends along the slope of the rail portion 31 of the transition rail 30. The protrusion 19 of the step 18 placed on the transition rail 30 at the passage outer height H ₂ moves from the other end 31 b of the transition rail 30 onto the fixed rail 34. Thus, since the distal end side of the steps 18 of the movable passage 14 is sequentially moved to the outer-conduit height H _2, the length in the longitudinal direction N of the passable region 15, a distance distal tunnel 4 has moved a short Become.

[Second Embodiment]
Next, a boarding bridge according to a second embodiment of the present invention will be described with reference to FIGS.
In the first embodiment described above, the length of one slide plate 23 in the longitudinal direction has a length corresponding to a plurality of sheets in step 18, but as described in the present embodiment, the present invention One slide plate 53 may be provided for each protrusion 19 provided in step 18. In the present embodiment, the description of the same components as those in the first embodiment is omitted.

  The movable passage portion 14 includes a plurality of steps 18 and a support portion 52 such as a slide plate 53 that supports the step 18.

The support portion 52 according to the present embodiment includes a slide plate 53, a bracket 54, a coil spring 55, and the like.
The slide plate 53 is placed on the bracket 54. The brackets 54 are provided at equal intervals along the longitudinal direction of the distal end tunnel 4.
The coil spring 55 is a compression spring, and is installed between the slide plate 53 and the inner wall surface of the panel 9 of the front end tunnel 4. For example, one coil spring 55 is installed at the center of the slide plate 53. A plate spring may be provided instead of the coil spring 55.

  The slide plate 53 is movable on the bracket 54 in the width direction of the movable passage portion 14. When the slide plate 53 is pressed by the projection 62 formed on the transition rail 60, the slide plate 53 moves toward the outside of the movable passage portion 14 and is biased by the coil spring 55, so that the slide plate 53 moves toward the movable passage portion 14. Moving.

  The slide plate 53 includes a flat plate 57 on which the protruding portion 19 is placed, a rising plate 58 provided in a direction perpendicular to the flat plate 57, and the like. The rising plate 58 is in contact with the protrusion 62 provided on the transition rail 60.

The transition rail 60 includes a rail portion 61 on which the protruding portion 19 in step 18 slides, and a protrusion 62 that presses the rising plate 58 of the slide plate 53.
The transition rail 60 is fixed to the proximal end tunnel 3. The transition rail 60 has an inclined surface that connects between the passage height H1 where the movable passage portion 14 is installed and the passage outer height H2. The protrusion 62 is formed at substantially the same height as the position where the slide plate 53 is installed.

  As the proximal end tunnel 3 moves relative to the distal end tunnel 4, the contact position between the protrusion 62 and the slide plate 53 changes. When the slide plate 53 is moved to the outside of the movable passage portion 14 by the protrusion 62, the distance between the slide plate 53 and the step 18 is widened. Further, when the slide plate 53 is moved toward the movable passage portion 14 by the urging force of the coil spring 55, the distance between the slide plate 53 and the step 18 is narrowed.

  Therefore, when the contact position between the protrusion 62 and the slide plate 53 changes, the protrusion 19 of the step 18 moves onto the slide plate 53 at one end 61 a of the rail 61, or the rail 61 of the transition rail 60. Or move up. Further, at the other end portion 61 b of the slide plate 53, the projecting portion 19 of the step 18 moves onto the transition rail 60 or moves to the fixed rail 34 (see FIGS. 20 and 24) of the distal end tunnel 4. Furthermore, when the transition rail 60 relatively moves in the longitudinal direction of the boarding bridge 1, the step 18 located on the transition rail 60 moves in the vertical direction along the inclined surface.

  In the present embodiment, since one slide plate 53 is provided for one projecting portion 19, unlike the first embodiment, a connecting portion for interlocking a plurality of slide plates 53 is not necessary.

  The slide plate 53 has a support plate 59 protruding outward. The support plate 59 is sandwiched between the fixing portion 56 on the bracket 54. The fixing portion 56 is fixed to the bracket 54. Thereby, when a load is applied to Step 18, the fixing portion 56 supports the support plate 59, so that the Step 18 can be prevented from falling with the slide plate 53. Note that a gap is provided between the fixed portion 56 and the bracket 54 so that the support plate 59 can slide, and the slide plate 53 can slide on the bracket 54.

Next, the operation of the boarding bridge according to the present embodiment described above will be described.
When the tip tunnel 4 moves toward the aircraft 10, the step 18 placed at the passage outside height H ₂ moves from the other end portion 60 b of the transition rail 60 to the rail portion 61 of the transition rail 60. The upper step 18 rises to the passage height H ₁ along the slope of the rail portion 61 of the transition rail 60. At the passage height H ₁ , the slide plate 53 that has come into contact with the protrusion 62 moves outward in the width direction of the passage by the protrusion 62. Thereby, since the space | interval of the slide plate 53 and step 18 spreads, the space which the protrusion part 19 of step 18 can raise along the transition rail 60 arises.

When the tip tunnel 4 moves toward the aircraft 10, the protruding portion 19 of the step 18 placed on the transition rail 60 at the passage height H ₁ moves from the one end 61 a of the transition rail 60 to the slide plate 53. Move up. Thereby, since the rear end side of the steps 18 of the movable passage 14 is sequentially moved to the passageway height H _1, the length in the longitudinal direction N of the passable region 15, a distance distal tunnel 4 is moved longer Become.
At this time, the opening / closing passage portion 17 is retracted upward by the drive device so that the opening / closing passage portion 17 is not damaged by rubbing the step 18 in which the opening / closing passage portion 17 moves.

On the other hand, when the front end tunnel 4 moves toward the rotander 2, the projecting portion 19 of the step 18 placed on the slide plate 53 moves from the slide plate 53 to one end portion 61 a of the transition rail 60. At the passage height H ₁ , the slide plate 53 that has come into contact with the protrusion 62 moves outward in the width direction of the passage by the protrusion 62. Thereby, since the space | interval of the slide plate 53 and step 18 spreads, the space which the protrusion part 19 of step 18 can descend | fall along the transition rail 60 arises.

When the tip tunnel 4 moves toward the rotander 2, the step 18 on the transition rail 60 descends along the slope of the rail portion 61 of the transition rail 60. The protrusion 19 of step 18 placed on the transition rail 60 at the passage outer height H ₂ moves from the other end 61 b of the transition rail 60 onto the fixed rail 34. Thus, since the distal end side of the steps 18 of the movable passage 14 is sequentially moved to the outer-conduit height H _2, the length in the longitudinal direction N of the passable region 15, a distance distal tunnel 4 has moved a short Become.

The present invention is not limited to the above-described boarding bridges of the first and second embodiments. For example, the present invention may be applied to a boarding bridge in which an intermediate tunnel is provided between the proximal tunnel 3 and the distal tunnel 4. it can.
In this case, the intermediate tunnel is also provided with a movable passage portion 14 having substantially the same structure as the movable passage portion 14 in the first embodiment. One end of the movable passage portion 14 of the intermediate tunnel is fixed at a position close to the other end portion of the front end tunnel 4. The other end of the movable passage portion 14 of the tip tunnel 4 is lowered from the vicinity of the tip portion of the intermediate tunnel to the position outside the passage. A plurality of intermediate tunnels may be provided.

  Moreover, in the said embodiment, although the channel | path of the movable channel | path part 14 is comprised by the step 18 divided | segmented into the longitudinal direction, this invention is not limited to this example. For example, a wide belt member may be used instead of step 18. The belt member is provided with a reinforcing material inside to enhance the strength. The belt member is supported on the support portion 22, the transition rail 30, and the fixed rail 34 by a protruding portion such as a roller disposed at a predetermined interval along the longitudinal direction N.
