Description

  The present invention relates to a boarding bridge, and more particularly to a boarding bridge suitable for an aircraft having a door that pivots or slides in a vertical direction.

  Conventionally, boarding bridges are often used as aircraft lifting devices. The boarding bridge is a tunnel-like walking passage that connects an airport terminal building and an aircraft. The boarding bridge enables passengers to get on and off directly between the terminal building and the aircraft (see, for example, Patent Document 1).

  The boarding bridge disclosed in Patent Document 1 includes a rotor connected to a terminal building, a telescopic tunnel portion connected to the rotor, and a cab provided at the tip of the tunnel portion.

  As shown in FIG. 24, when passengers get on and off, the cab 201 is located between the entrance 203 of the aircraft 202 and the tunnel portion. Therefore, the cab 201 includes a floor 206 that connects the entrance / exit 203 and the tunnel portion.

When passengers get on and off, the cab 201 is mounted in the vicinity of the door 205 of the aircraft 202. When the cab 201 is mounted on the aircraft 202, the closure 204 provided at the tip of the cab 201 is deployed to cover the upper side and the side of the door 205. This prevents rain and wind from entering the entrance 203 when the door 205 is opened. Thereafter, the door 205 is opened and the entrance 203 is opened. Passengers get on and off through the entrance 203.
Japanese Patent Laid-Open No. 2002-37196

  However, as described below, the conventional boarding bridge cannot be mounted on an aircraft depending on the type of door of the aircraft.

  That is, the aircraft 202 targeted by the conventional boarding bridge has a door 205 that slides in the horizontal direction as shown in FIG. 24 or a door that rotates in the horizontal direction with the vertical axis as a fulcrum.

  However, for example, in a so-called small aircraft, there is an aircraft including a door that rotates in the vertical direction with a lower end portion as a fulcrum. An aircraft with a door that slides downward is also conceivable. However, in an aircraft having this type of door, even if an attempt is made to open the door after the cab is mounted, the door interferes with the cab floor and cannot be opened.

  As described above, the conventional boarding bridge cannot be mounted on an aircraft provided with a door that pivots in the vertical direction with the lower end portion as a fulcrum or a door that slides downward.

  The present invention has been made in view of such a point, and an object thereof is to provide a boarding that can be mounted on an aircraft provided with a door that pivots in the vertical direction or a door that slides in the downward direction with the lower end as a fulcrum. To provide a bridge.

  A boarding bridge according to the present invention is a boarding bridge having a cab to be mounted on an aircraft, and the cab is a concave part in which a part on a tip side is recessed on a root side, and a vertical part with a lower end part as a fulcrum. A floor formed with a recessed part for door escape that allows passage of an aircraft door that rotates in a direction or an aircraft door that slides downward, a storage state that does not block the recessed part, and a part or all of the recessed part is blocked A state change is possible between the deployed state and a transfer platform that forms a passage that connects the floor and the aircraft in the deployed state.

  According to the boarding bridge, since the recess for door escape is formed on the floor of the cab, even after the cab is mounted on the aircraft, the aircraft door can be rotated vertically or slid downward. There is no risk that the door will interfere with the cab floor. Therefore, the door can be opened. In addition, after the door of the aircraft is opened, the passage can be formed between the cab floor and the aircraft by changing the state of the transfer stand from the stowed state to the expanded state. Thereby, passengers can get on and off the aircraft through the transfer platform.

  The transfer table may be a slide type transfer table that can move forward and backward in the front-rear direction from the concave portion of the floor.

  According to the boarding bridge, it is possible to realize a transfer stand that can be easily changed between the storage state and the unfolded state. Moreover, the length of the passage connecting the cab floor and the aircraft can be easily adjusted by adjusting the slide amount before and after the transfer platform.

  The transfer stand may be a flip-up type transfer stand whose root side is supported so as to be rotatable about the front horizontal axis.

  Also in the boarding bridge, it is possible to realize a transfer stand that can be easily changed between the stored state and the deployed state. In addition, unlike the slide type pedestal, there is no need to slide the pedestal to the base of the floor, so the length of the cab floor in the front-rear direction can be kept relatively short, and the cab can be downsized. it can.

  It is preferable that the boarding bridge includes a left-right moving mechanism that moves the transfer platform in the left-right direction.

  According to the boarding bridge, the horizontal position of the transfer board can be finely adjusted without moving the cab itself by moving the transfer board in the left-right direction by the left-right movement mechanism. That is, the right and left positions of the transfer platform can be accurately aligned with the entrance of the aircraft without moving the cab itself.

  The boarding bridge preferably includes a turning mechanism for turning the transfer platform around a vertical axis.

  According to the boarding bridge, the direction of the transfer stand can be finely adjusted without turning the cab itself by turning the transfer stand by the turning mechanism. That is, the direction of the transfer platform can be accurately adjusted with respect to the entrance of the aircraft without turning the cab itself.

  It is preferable that the boarding bridge includes a handrail that is stored together with the transfer table in the storage state and is expanded together with the transfer table in the expanded state. The handrail may be manually deployed or automatically deployed.

  According to the boarding bridge, the handrail is developed together with the transfer platform in the deployed state. Therefore, pedestrians walking on the transfer platform can get on and off safely and smoothly using the handrail.

  The boarding bridge includes a guard member that forms a side wall that is stowed from the both sides of the transfer stand by being stowed together with the transfer stand in the stowed state, and being deployed together with the transfer stand in the unfolded state. Is preferred. The guard member may be manually deployed or automatically deployed.

  According to the above boarding bridge, when the transfer stand is in the unfolded state, the guard member is unfolded to form side walls on both sides of the transfer stand. Therefore, pedestrians and the like (including wheelchairs and the like) can pass more safely on the transfer platform.

  The boarding bridge has a gap formed between a side portion of the transfer stand in the unfolded state and the floor, and is unfolded so as to cover the gap when the transfer stand is in the unfolded state. It is preferable to provide an auxiliary table. In addition, an auxiliary | assistant stand may be expand | deployed manually and may be expand | deployed automatically.

  The boarding bridge can also be mounted on an aircraft having a door that slides or pivots laterally. However, when mounted on such an aircraft, if there is a gap between the side of the platform and the cab floor when the platform is deployed, it will look good for pedestrians walking on the platform. Is not good. Further, when a wheelchair or the like passes on the transfer platform, the wheel may be caught in the gap. However, according to the boarding bridge, when the transfer table is in the expanded state, the gap can be covered by expanding the auxiliary table. Therefore, appearance can be improved. In addition, wheelchairs and the like can pass through the transfer platform smoothly.

  The boarding bridge moves between the operation panel and a normal position which is a side position of the concave portion on the front end side of the floor and a retracted position behind the normal position to guide the movement of the operation panel. And a guide mechanism.

  A person who operates the boarding bridge installs the cab while visually confirming the position of the door of the aircraft while being positioned at the front end side of the cab floor. Therefore, from the viewpoint of facilitating the operation of the boarding bridge, it is preferable that the operation panel is disposed on the front end side of the cab. However, when the boarding bridge is mounted on an aircraft having a door that slides or rotates in the lateral direction, the door that has been slid or rotated may interfere with the operation panel. However, according to the boarding bridge, the interference between the door and the operation panel can be prevented by moving the operation panel to the retracted position. Therefore, the boarding bridge is preferably used not only for an aircraft having a door that pivots in the vertical direction with the lower end as a fulcrum, but also for an aircraft having a door that slides or pivots in the lateral direction. Can do.

  The boarding bridge includes a cab turning mechanism for turning the cab, and the cab turning mechanism is based on a first turning speed that is a turning speed when the cab approaches the aircraft, and the first turning speed. It is preferable that the cab is turned at a speed of at least two steps of a second turning speed that is a turning speed when the position of the transfer platform is adjusted to the position of the door of the aircraft.

  Thus, when the cab is brought closer to the aircraft, the cab can be turned at the first turning speed that is a relatively high turning speed, and the cab can be brought closer to the aircraft more quickly. On the other hand, after the cab is brought close to the aircraft, the cab can be turned at the second turning speed, which is a relatively low turning speed, so that the position or orientation of the transfer platform can be easily adjusted to the aircraft door. Become.

  As described above, according to the present invention, it is possible to provide a boarding bridge that can be mounted on an aircraft provided with a door that pivots in the vertical direction with the lower end portion as a fulcrum or a door that slides downward.

<First Embodiment>
As shown in FIG. 1, the boarding bridge 1 according to the embodiment includes a rotor (base circular chamber) 4 connected to an airport terminal building 2, a tunnel part 5 connected to the rotor 4, and a tip of the tunnel part 5. And a cab (tip circular chamber) 6 provided at the front.

  The rotor 4 is supported by a support base 7 so as to be rotatable about a vertical axis. The tunnel unit 5 includes a first tunnel 5a and a second tunnel 5b. The second tunnel 5b is assembled to be slidable with respect to the first tunnel 5a. As the second tunnel 5b slides relative to the first tunnel 5a, the entire tunnel portion 5 expands and contracts. The second tunnel 5b is provided with a drive column 8 as a support leg. Drive wheels 9 are provided at the lower end of the drive column 8.

  FIG. 2 is a perspective view schematically showing the main part of the cab 6. The cab 6 is formed in a substantially box shape whose front side is open, and includes a floor 11, a side wall 12, and a ceiling 13. The cab 6 is configured to be rotatable about a vertical axis 16 by a turning mechanism 15 disposed below the floor 11. Closures 17 are provided at the front end portions of the left and right side walls 12 and the front end portion of the ceiling 13.

  In the following description, the open side of the cab 6 is referred to as the front end side or the front side, and the tunnel portion 5 side of the cab 6 is referred to as the root side or the rear side. Further, the right side and the left side refer to the right side and the left side when the tip side is viewed from the base side of the cab 6, respectively.

  At the center in the left-right direction on the front end side of the floor 11, a recess 18 that is recessed toward the base side is formed. As described above, a part of the front end side of the floor 11 is recessed toward the base side, so that a door escape space 18 a is formed at the center of the floor 11. In addition, since the concave portion 18 is formed, the left and right side portions of the concave portion 18 are protruding portions 19L and 19R that protrude to the tip side. A bumper 20 is attached to the tips of the protruding portions 19L and 19R.

  When passengers get on and off, the door 30 is bridged in the door escape space 18 a from the recess 18 of the floor 11 to the entrance 102 of the aircraft 100. FIG. 3 is a diagram schematically showing the transfer table 30 and each device that drives the transfer table 30. As shown in FIG. 3, the cab 6 includes a forward / backward movement mechanism 40 that slides the transfer table 30 back and forth, a left / right movement mechanism 50 that slides the transfer table 30 left and right, and a turning mechanism that changes the orientation of the transfer table 30. 60.

  As shown in FIG. 2, an operation panel 21 is disposed on the left side of the recess 18 in the floor 11. That is, the operation panel 21 is arranged on the front end side and the left side of the floor 11. The operation panel 21 is a device operated by an operator. Through the operation panel 21, the driving wheel 9, the turning mechanism 15 of the cab 6, the forward / backward moving mechanism 40 of the transfer table 30, the left / right moving mechanism 50, and the turning mechanism are provided. 60 etc. are operated.

  The turning mechanism 15 of the cab 6 includes a drive source such as a motor, and can turn the cab 6 at different turning speeds. In addition, the specific structure of the apparatus which makes turning speed variable is not limited at all. For example, an inverter or the like can be suitably used as such a device.

  4A and 4B are diagrams for explaining the forward / backward moving mechanism 40 of the transfer table 30. FIG. 4A is a side view of the transfer table 30, and FIG. As shown in FIG. 4, a rack 41 extending in the front-rear direction is provided on the back side of the transfer table 30. A pinion 42 that meshes with the rack 41 and a motor 43 that drives the pinion 42 are disposed below the transfer table 30. Rollers 44 that run in the front-rear direction are attached to the left and right sides of the transfer platform 30. In the present embodiment, two pairs of left and right rollers 44 are provided at an interval in the front-rear direction, and a total of four rollers 44 are provided. However, the number of rollers 44 is not particularly limited. As shown in FIG. 3, the transfer stand 30 is inserted into a support case 45 extending in the front-rear direction, and the roller 44 is supported on a bottom plate 45 a (see FIG. 5A) of the support case 45. When the motor 43 rotates, the driving force of the motor 43 is transmitted to the transfer table 30 via the rack 41 and the pinion 42, and the transfer table 30 moves in the front-rear direction. Thus, the motor 43 constitutes a drive source that moves the transfer table 30 in the front-rear direction.

  5A and 5B are diagrams for explaining the left-right moving mechanism 50. FIG. 5A is a side view of the transfer table 30, and FIG. 5B is a plan view of the transfer table 30. FIG. As shown in FIG. 5, rollers 51 that run in the left-right direction are provided at the front end and the rear end of the support case 45. In the present embodiment, two pairs of front and rear rollers 51 are provided with a space left and right, and a total of four rollers 51 are arranged. However, the number of rollers 51 is not particularly limited. On the front side and the rear side of the support case 45, left and right rails 52 are arranged, respectively. Each roller 51 is disposed on a rail 52. As shown in FIG. 5B, the power cylinder 53 is connected to the right side of the support case 45. When the power cylinder 53 pushes the support case 45 leftward or pulls it rightward, the roller 51 attached to the support case 45 travels on the rail 52 and the support case 45 slides leftward and rightward. As a result, the transfer table 30 inserted into the support case 45 also slides in the left-right direction. Thus, the power cylinder 53 constitutes a drive source that moves the transfer table 30 in the left-right direction.

  6A and 6B are diagrams for explaining the turning mechanism 60. FIG. 6A is a side view schematically showing the structure of the turning mechanism 60, and FIG. 6B is a plan view thereof. As shown in FIG. 6, a rotating shaft 62 extending vertically downward is fixed to the lower end of the support case 45, and the rotating shaft 62 is supported by a bearing 61 so as to be rotatable about the vertical axis. Further, three rollers 63 arranged in the left-right direction are arranged in front of the rotation shaft 62. Each roller 63 is supported by a roller guide 64 so as to be rotatable about a horizontal axis extending in the front-rear direction. The support case 45 is supported by these rollers 63. As shown in FIG. 6B, a power cylinder 65 is connected to the right side of the support case 45. When the power cylinder 65 pushes the support case 45 to the left or pulls it to the right, the support case 45 rolls on the roller 63 and turns around the axis of the rotation shaft 62. Thus, the power cylinder 65 constitutes a drive source for turning the transfer platform 30. Note that the three rollers 63 may be arranged on a circumference around the rotation shaft 62, but in the present embodiment, they are arranged linearly in the left-right direction. This is because, in this embodiment, the amount of turning (turning angle) by the turning mechanism 60 is very small, and even such a linear arrangement has no practical problem.

  As shown in FIG. 3, the transfer stand 30 is provided with a folding handrail 70 that can be stored and unfolded. Next, the handrail 70 will be described with reference to FIGS. 7 and 8. As shown in FIG. 8, the handrail 70 is provided on both the left and right sides of the transfer stand 30. As shown in FIG. 7, each handrail 70 extends in the front-rear direction. Each handrail 70 is supported by the first arm 75 and the second arm 76. The 1st arm 75 and the 2nd arm 76 are connected via the pin 73 in each middle part. The upper end portion 75 a of the first arm 75 supports the handrail 70 and is slidable in the front-rear direction with respect to the handrail 70. The lower end 75b of the first arm 75 is rotatably supported by the mounting seat 31a of the support plate 30a. An upper end portion 76 a of the second arm 76 is rotatably connected to the handrail 70 and supports the handrail 70. The lower end portion 76b of the second arm 76 is slidable in the front-rear direction on the support plate 30a and is supported by the support plate 30a.

  As shown in FIG. 8A, safety plates 71 are attached to the left and right sides of the transfer table 30 via hinges 72. By means of this hinge 72, the safety plate 71 is rotatable about a horizontal axis extending in the front-rear direction. The safety plate 71 takes a horizontal posture when in the housed state (see FIG. 8A) and takes a vertical posture when in the unfolded state (see FIG. 8B). The pivotable angle of the hinge 72 is 90 degrees, and the safety plate 71 is not tilted inward from a vertically upright state. In the unfolded state, the safety plate 71 forms side walls 71 a that rise from both side portions of the transfer table 30, and guards both sides of the transfer table 30. The safety plate 71 is stored when the transfer table 30 is in the stored state, and is expanded when the transfer table 30 is in the expanded state.

  As shown in FIGS. 9 and 10, an auxiliary plate 80 that slides to the left and right is housed inside the protrusions 19 </ b> L and 19 </ b> R of the floor 11. Supporting pieces 81 that support the tip of the auxiliary plate 80 are provided on the left and right side surfaces of the transfer table 30. In addition, the support piece 81 may be integral with the transfer stand 30, and may be a separate body. The member that supports the auxiliary plate 80 is not limited to the support piece 81 extending in the front-rear direction, and may be a rod-like body that is intermittently disposed in the front-rear direction. Alternatively, a groove may be formed on the side surface of the transfer board 30 and the tip of the auxiliary plate 80 may be inserted into the groove. In the present embodiment, the auxiliary plate 80 is put in and out by an operator. That is, the auxiliary plate 80 is a manual type. However, the auxiliary plate 80 may be automatically deployed and stored.

  In the present embodiment, the operation panel 21 is movable back and forth. Specifically, as shown in FIG. 13, the operation panel 21 is movable between a normal position located on the front end side of the floor 11 and a retracted position located behind the normal position. As shown in FIGS. 11 and 12, a rail 85 extending in the front-rear direction is provided on the left side wall 12 of the cab 6. Two rails 85 are provided vertically. In addition, a rail 86 extending in the front-rear direction is also provided on the left protrusion 19L of the floor 11. Two rails 86 are provided on the left and right. A roller 87 that engages with the rail 85 is attached to the left side surface of the operation panel 21. A roller 88 that engages with the rail 86 is attached to the lower end surface of the operation panel 21. Thereby, the operation panel 21 is slidable between the normal position and the retracted position by the roller 87 being guided by the rail 85 and the roller 88 being guided by the rail 86. In the present embodiment, the operation panel 21 is manually moved. However, the operation panel 21 can be automatically moved by providing a drive mechanism.

  The boarding bridge 1 can be used for both an aircraft having a door that pivots or slides in the vertical direction and an aircraft that has a door that slides or pivots in the horizontal direction. First, a method of mounting the boarding bridge 1 on an aircraft provided with a door that rotates in the vertical direction will be described.

  First, as shown in FIG. 14, when the operator operates the operation panel 21, the cab 6 is moved from the terminal building 2 side to the aircraft 100 side, and the cab 6 is brought close to the door 101 of the aircraft 100. At this time, the operator turns the cab 6 at a predetermined first turning speed.

  After the cab 6 moves to the vicinity of the door 101 of the aircraft 100, the turning speed of the cab 6 is reduced from the first turning speed to the second turning speed (<first turning speed), and the cab 6 is turned slowly. Then, the position or orientation of the cab 6 is finely adjusted until it faces the door 101 directly in front.

  Thereafter, the cab 6 is brought close to the aircraft 100 until the bumper 20 at the tip of the cab 6 approaches the aircraft 100. Next, the closure 17 of the cab 3 is developed so as to cover the door 101. Next, the door 101 of the aircraft 100 is opened (see FIG. 15). At this time, the recess 11 is formed in the floor 11 of the cab 3, and the door escape space 18 a is formed in the floor 11, so that there is no interference between the door 101 and the floor 11.

  Next, the left / right position of the transfer platform 30 is adjusted to the entrance / exit 102 of the aircraft 100 by the left / right moving mechanism 50 (see FIG. 3), and the orientation of the transfer platform 30 is adjusted to the entrance / exit 102 of the aircraft 100 by the turning mechanism 60. That is, fine adjustment of the position and orientation of the transfer platform 30 in the left-right direction is performed. Thereafter, the motor 43 of the back-and-forth movement mechanism 40 is driven, and the transfer table 30 is advanced until the front end of the transfer table 30 is positioned slightly in front of the entrance 102 of the aircraft 100. Further, the height position of the cab 6 is finely adjusted so that the upper surface of the transfer platform 30 and the floor surface of the entrance 102 are at the same height.

  The door 101 of the aircraft 100 according to the present embodiment has a trap 103 formed on the back side. Reference numeral 104 denotes a handrail for the trap 103. The transfer platform 30 passes between the left and right handrails 104 and advances toward the entrance 102. When the transfer platform 30 reaches the entrance 102, the advance of the transfer platform 30 is stopped. Thereby, the transfer stand 30 is bridged between the aircraft 100 and the floor 11 (see FIG. 16).

  Next, the left and right safety plates 71 are opened inward, and the left and right handrails 70 are pulled upward (see FIG. 8B). As a result, the first arm 75 and the second arm 76 stand up. Then, the first arm 75 or the second arm 76 is locked so that the handrail 70 does not fall down. At this time, the safety plate 71 is prevented from tilting inward by the hinge 72, and is prevented from tilting outward by the arms 75 and 76. Therefore, the safety plate 71 is held in an upright state.

  As described above, a walking path in which both sides of the foot are guarded by the safety plate 71 and the handrail 70 is disposed between the floor 11 and the entrance 102 of the aircraft 100 can be formed. Therefore, passengers can get on and off smoothly through the walking passage.

  In addition, after boarding / exiting a passenger etc. is complete | finished, the operation | movement reverse to the above-mentioned is performed. That is, after the handrail 70 is stored, the transfer table 30 is retracted, and the transfer table 30 is stored on the floor 11. Then, the door 101 of the aircraft 100 is closed. Thereafter, the closure 17 is stored and the cab 3 is detached from the aircraft 100.

  The above is the mounting method of the boarding bridge 1 to the aircraft 100 having the door 101 that rotates in the vertical direction with the lower end as a fulcrum. In addition, although description is abbreviate | omitted, this boarding bridge 1 can be similarly mounted | worn with respect to the aircraft which has a door which slides below.

  Next, a method of mounting the boarding bridge 1 on the aircraft 100 (see FIG. 13) having the door 101a that slides or rotates in the lateral direction will be described.

  First, the operator operates the operation panel 21 to approach the door 101a of the aircraft 100 while turning the cab 6 at the first turning speed. Then, the position or orientation of the cab 6 is adjusted until it faces the door 101a of the aircraft 100. Note that it is not necessary to bridge the transfer platform 30 for the aircraft 100 having the door 101a that slides or pivots in the lateral direction, so the turning speed of the cab 6 is changed from the first turning speed to the second turning speed. It is not always necessary to slow down. However, the turning speed of the cab 6 may be changed from the first turning speed to the second turning speed after the cab 6 is brought close to the aircraft 100 in order to easily finely adjust the position or orientation of the cab 6. Of course.

  Thereafter, the cab 6 is brought close to the aircraft 100 until the bumper 20 at the tip of the cab 6 approaches the aircraft 100. Next, the closure 17 of the cab 6 is deployed so as to cover the door 101 a of the aircraft 100.

  Next, the motor 43 of the back-and-forth movement mechanism 40 is driven, and the transfer stand 30 is moved until the front end of the transfer stand 30 reaches a position equal to or slightly behind the front end of the floor 11 (left and right protrusions 19L and 19R). Advance 30.

  However, in this state, a gap 82 is generated between the transfer platform 30 and the protruding portions 19L and 19R of the floor 11 (see FIGS. 9B and 10B). Then, next, the auxiliary plate 80 is developed, and the gap 82 is covered with the auxiliary plate 80. Thereby, a floor without a gap is formed by the entire floor 11, the auxiliary plate 80, and the transfer platform 30.

  Thereafter, the door 101a of the aircraft 100 is slid or rotated laterally. However, the door 101a may interfere with the operation panel 21 at this time. In such a case, the operation panel 21 is retracted from the normal position to the retracted position in advance before opening the door 101a (see FIG. 13). Thereby, the door 101a can be opened sufficiently.

  Thus, passengers can get on and off the aircraft 100 through the cab 6.

  In addition, after boarding / exiting a passenger etc. is complete | finished, the operation | movement reverse to the above-mentioned is performed. That is, the door 101a of the aircraft 100 is closed, and the operation panel 21 is advanced from the retracted position to the normal position as necessary. Further, the auxiliary plate 80 is accommodated. Further, the transfer stand 30 is retracted to accommodate it. Thereafter, the closure 17 is stored and the cab 3 is detached from the aircraft 100.

  According to the boarding bridge 1 according to the present embodiment, since the door escape recess 18 is formed in the floor 11 of the cab 6, after the cab 6 is mounted on the aircraft 100, the door 101 of the aircraft 100 is moved vertically. There is no possibility that the door 101 interferes with the floor 11 of the cab 6 even if it is rotated or slid downward. In addition, after opening the door 101 of the aircraft 100, the passage 30 can be formed between the floor 11 of the cab 6 and the aircraft 100 by moving the transfer stand 30 from the housed state to the deployed state. . As a result, passengers can get on and off the aircraft 100 through the transfer platform 30.

  In the present embodiment, the transfer table 30 is a slide type transfer table 30 that can be moved forward and backward from the recess 18 of the floor 11. As a result, it is possible to realize a transfer stand that can be easily changed between the storage state and the unfolded state. Further, by adjusting the slide amount before and after the transfer platform 30, the length of the passage connecting the floor 11 of the cab 6 and the aircraft 100 can be easily adjusted.

  The boarding bridge 1 includes a left-right moving mechanism 50 that moves the transfer platform 30 in the left-right direction. Thereby, the left-right position of the transfer stand 30 can be finely adjusted without moving the cab 6 itself. That is, the right and left positions of the transfer platform 30 can be accurately aligned with the entrance 102 of the aircraft 100 without moving the cab 6 itself.

  Further, the boarding bridge 1 includes a turning mechanism 60 that turns the transfer platform 30 around the vertical axis. Thereby, the direction of the transfer stand 30 can be finely adjusted without turning the cab 6 itself. That is, the direction of the transfer platform 30 can be accurately aligned with the entrance 102 of the aircraft 100 without turning the cab 6 itself.

  The boarding bridge 1 includes a handrail 70 that is stored together with the transfer table 30 when the transfer table 30 is in the stored state, and that is expanded together with the transfer table 30 when the transfer table 30 is in the expanded state (see FIG. 7). Thereby, the pedestrian etc. who walk on the delivery stand 30 can get on and off safely and smoothly using the handrail 70.

  Further, the boarding bridge 1 is stored together with the transfer table 30 when the transfer table 30 is in the storage state, and is expanded with the transfer table 30 when the transfer table 30 is in the expanded state, whereby side walls 71a rising from both side portions of the transfer table 30. Is provided (see FIG. 8). Therefore, a pedestrian or the like (including a wheelchair or the like) can pass on the transfer platform 30 more safely.

  The boarding bridge 1 includes an auxiliary plate 80 that is deployed so as to cover the gap 82 between the side of the delivery platform 30 and the floor 11 when the delivery platform 30 is in the deployed state (see FIGS. 9 and 9). 10). Therefore, when mounted on an aircraft having a door that slides or pivots in the lateral direction, the gap 82 can be covered, so that the appearance can be improved. Moreover, since there is no fear of wheel removal, a wheelchair etc. can be passed smoothly.

  The boarding bridge 1 includes a movement guide mechanism (rails 85 and 86) for guiding the movement of the operation panel 21 between a normal position and a retracted position. Therefore, when mounted on the aircraft 100 having the door 101a that slides or rotates in the lateral direction, interference between the door 101a and the operation panel 21 when the door 101a is opened can be avoided.

  The boarding bridge 1 can turn the cab 6 at two speeds (first turning speed and second turning speed). Therefore, when the cab 6 is brought close to the aircraft 100, the cab 6 can be turned at the first turning speed, which is a relatively high turning speed, and the cab 6 can be quickly approached. On the other hand, after the cab 6 is brought close to the aircraft 100, the cab 6 can be turned at the second turning speed that is a relatively low turning speed, so that the position or orientation of the transfer platform 30 is set to the door 101 of the aircraft 100. It becomes easy to match.

  In the boarding bridge 1, the vertical position of the cab 6 is controlled so that the transfer platform 30 is in a horizontal state. The drive column 8 (see FIG. 1) is provided with a vertical movement mechanism (not shown), and the cab 6 is raised or lowered by this vertical movement mechanism. Specifically, even if the weight of the aircraft 100 changes as passengers get on and off and the height of the entrance 102 changes, an auto-leveler (not shown) provided near the protrusion 19L or 19R The vertical movement mechanism of the drive column 8 is controlled so that the cab 6 follows as the aircraft 100 moves up and down. As a result, the transfer stand 30 is controlled to be in a horizontal state.

<Second Embodiment>
1st Embodiment was the slide-type delivery stand 30 with which a delivery stand slides back and forth. However, the transfer stand according to the present invention is bridged between the storage state stored in the cab 6 so as not to obstruct the opening and closing of the door 101 of the aircraft 100, and the floor 11 of the cab 6 and the entrance 102 of the aircraft 100. What is necessary is just to be movable between expansion | deployment states, and is not necessarily limited to what slides back and forth. The second embodiment is different from the first embodiment in the moving method of the transfer platform.

  As shown in FIG. 17, the transfer platform according to the second embodiment is a so-called flip-up transfer platform 30b. Specifically, the base side of the transfer platform 30b is supported so as to be rotatable about a horizontal axis in the door escape space 18a. In other words, the base side of the transfer platform 30b is supported so as to be rotatable about the horizontal axis on the rear side of the front end of the floor 11 (the front ends of the protruding portions 19L and 19R).

  As shown in FIG. 18, a hinge pin 35 that constitutes a part of the hinge mechanism is attached to the base side of the transfer stand 30b. An encoder 36 that detects the rotation angle of the hinge pin 35 is attached to the hinge pin 35. The encoder 36 detects the inclination angle of the transfer platform 30b from the horizontal plane.

  An arm 38 is provided at the lower end on the base side of the transfer table 30b. A power cylinder 91 is disposed below the floor 11 as a drive mechanism for rotating the transfer platform 30b. When the arm 92 of the power cylinder 91 extends forward, the arm 38 is pushed forward, and the transfer stand 30b is pivoted about the hinge pin 35 and is flipped up (stored state). On the other hand, when the arm 92 of the power cylinder 91 is contracted, the transfer platform 30b is rotated downward by its own weight and becomes a horizontal state (deployed state).

  When the transfer table 30b is installed, the direction of the transfer table 30b is adjusted to the entrance 102 of the aircraft 100. Thereafter, the motor of the back-and-forth movement mechanism 40 is driven to place the transfer platform 30 b on the floor of the entrance 102 of the aircraft 100.

  Also in this embodiment, the vertical position of the cab 6 is controlled so that the transfer platform 30b follows the change in the height position of the entrance 102 according to the weight change of the aircraft 100. Specifically, the drive column 8 (see FIG. 1) is provided with a vertical movement mechanism (not shown). When the drive column 8 extends upward, the cab 6 rises and the drive column 8 moves downward. When contracted, the cab 6 descends. In the present embodiment, the vertical movement mechanism of the drive column 8 is controlled so that the angle detected by the encoder 36 is a predetermined angle (the angle at which the transfer platform 30 is in a horizontal state), and the cab 6 is raised or lowered. Is called.

  Since other configurations are the same as those of the first embodiment, description thereof will be omitted.

  Also in this embodiment, substantially the same effect as in the first embodiment can be obtained. In addition, according to the present embodiment, the length of the cab 6 in the front-rear direction can be shortened.

  That is, as shown in FIG. 19, when the front / rear slide type transfer table 30 is used as in the first embodiment, the amount of movement of the transfer table 30 is increased. 35a is located considerably behind. Therefore, in order to store the transfer stand 30, the length of the cab 6 in the front-rear direction is increased. On the other hand, according to this embodiment, since the transfer stand 30b is a flip-up type, the amount of movement before and after the transfer stand 30b is small. That is, the transfer platform 30b only moves slightly back and forth for fine adjustment of the front and back position. Accordingly, the position of the rear end 35b of the transfer table 30b in the housed state is located on the front side compared to the position of the rear end 35a of the transfer table 30 of the first embodiment. Therefore, according to this embodiment, since the transfer stand 30b can be accommodated even if the length of the cab 6 is short, the length of the cab 6 can be shortened. Therefore, according to this embodiment, the cab 6 can be downsized.

  In addition, according to the present embodiment, even if the weight of the aircraft 100 changes with the passenger getting on and off, and the height of the entrance 102 changes, the hinge mechanism of the transfer stand 30b can be freely changed if it is a subtle change. Follow. On the other hand, if there is a change beyond a certain angle, the encoder 36 detects the inclination angle and the height of the cab 6 is controlled. Therefore, it is possible to always get on and off smoothly.

<Other embodiments>
The present invention is not limited to the above embodiment, and can be implemented in various other forms.

  As shown in FIG. 8, in the said embodiment, the safety board 71 was a rotational type. However, the safety plate 71 is not limited to a rotating one. As shown in FIGS. 20 and 21, the safety plate 71 may slide up and down. In this embodiment, as shown in FIG. 21B, the rear side of the safety plate 71 is connected to the first arm 75 via a pin 77. A slide hole 79 extending in the front-rear direction is formed on the front side of the safety plate 71. A pin 78 extending in the left-right direction is formed on the second arm 76. The pin 78 is inserted into the slide hole 79 of the safety plate 71 and can slide back and forth within the slide hole 79.

  When the handrail 70 is lifted, the first arm 75 and the second arm 76 rise. Since the second arm 76 and the safety plate 71 are connected via a pin 77, and the first arm 75 and the safety plate 71 are engaged via a pin 78, the first arm 75 and the second arm 76 are When standing up, the safety plate 71 is pulled upward by the first arm 75 and the second arm 76. As a result, the safety plate 71 shifts from the housed state (see FIGS. 20A and 21A) to the unfolded state (see FIGS. 20B and 21B). Note that after the handrail 70 is deployed, the first arm 75 and the second arm 76 are locked by the stopper 69. This prevents the handrail 70 from falling downward.

  As shown in FIG. 9, in the said embodiment, the auxiliary | assistant board 80 was a slide type. However, as shown in FIGS. 22 and 23, the auxiliary plate 80 may be pivotable. In this embodiment, the auxiliary plate 80 is attached to the protruding portions 19L and 19R of the floor 11 via a hinge 83.

  At the time of storage, the left auxiliary plate 80 is supported by the operation panel 21 via the chain 85a, and the right auxiliary plate 80 is supported by the protruding portion 19R of the floor 11 via the chain 85a. Thereby, the auxiliary | assistant board 80 does not fall down at the time of accommodation. On the other hand, at the time of deployment, each auxiliary plate 80 is removed from the chain 85a and tilted inward. Thereby, the gap 82 between the floor 11 and the transfer table 30 can be closed by the auxiliary plate 80.

  In the embodiment, the recess 18 of the floor 11 is formed at the center in the left-right direction of the floor 11. However, the position of the recess 18 may not be the center in the left-right direction of the floor 11 of the cab 6, and may be on the right side or the left side. Further, in the embodiment, the protruding portions 19L and 19R are formed on the left and right sides of the concave portion 18 of the floor 11. However, the recess 18 may be located at the left end or the right end of the floor 11 and the protrusion may be formed only on the right side or the left side of the recess 18.
