Description

  The present invention relates to a cab of an aircraft boarding bridge that is installed at an airport for passengers to board a passenger aircraft and is joined to an entrance of an aircraft, and more particularly to a cab having a movable floor structure and an aircraft using the same Regarding boarding bridge.

  An aircraft, such as a passenger aircraft, is provided with an entrance for introducing passengers, passengers, or workers (hereinafter referred to as passengers) into the cabin on its side, and is opened or closed by a passenger door. An aircraft boarding bridge (hereinafter referred to as “PBB: Passenger Boarding Bridge”) is arranged from the boarding gate in the airport building where passengers and the like are boarded to the entrance of the aircraft. The PBB is composed of a telescopic tunnel, a cab, and a rotander. The tunnel expands and contracts in response to boarding passengers and related work. One end of the tunnel is connected to the rotander, and the cab is connected to the other end. The rotunda is attached to the airport building or to a fixed bridge that is part of a building protruding from the airport building and connects the airport building and the tunnel. The cab connects the tunnel and the entrance / exit. The tunnel can swing around the center of the rotunda. In the present specification, the cab side of the tunnel is referred to as “front end” and the rotander side is referred to as “rear end”. As for the cab, the entrance / exit side is called the “front end” and the tunnel side is called the “rear end”.

  The cab is connected to the front end side of the tunnel, and performs fine adjustment of the position for rotating or moving up and down to join the entrance. When a PBB is used to board or get off (hereinafter referred to as boarding or the like) in an aircraft such as a passenger, the aircraft is parked near the PBB. The PBB approaches the aircraft greatly by the rotating operation by the rotander and the tunnel extending toward the entrance door of the aircraft. When the cab approaches the doorway of the aircraft, the tunnel stops extending, and is finely adjusted by the cab and joined to the aircraft doorway. The PBB is fixed when it almost matches the entrance / exit door of the aircraft, and the entrance / exit door is opened to allow passengers to board. Passengers and the like can use the PBB to safely board the aircraft regardless of the weather.

  Previously, the types of aircraft were limited, and the operation was mainly by large and medium-sized aircraft, and small aircraft complemented this. Therefore, in conventional airports, PBBs have been arranged as a central means for boarding dedicated to large and medium-sized aircraft. In recent years, however, small aircraft called economical so-called regional aircraft have become a worldwide trend as aircraft connecting metropolitan airports and regional airports or between regional airports. In regional aircraft, stairs for boarding or the like called air steer are attached to the inside (the inside of the aircraft at the time of closing) of the passenger door that opens or closes the entrance. For this reason, no trap or PBB is required for boarding a regional aircraft.

  Even in a regional aircraft, there is a demand to use a PBB that can be safely boarded in an aircraft. However, when trying to use a conventional large / medium-sized PBB as a regional machine, when opening the passenger door, the air steer and its handrail interfere with the cab floor, or the floor area and bellows become the size of the aircraft. There are problems such as incompatibility.

  For this reason, in the invention of the PBB for regional machines disclosed in Patent Document 1 and Patent Document 2, a recess recessed in the rear end direction is provided on the floor on the front end side of the cab, and the front and rear, right and left are movable within the recess. A slide-type delivery table is provided.

  However, when a PBB dedicated to a regional machine is introduced, the boarding gate of the PBB can be used only for the regional machine, and the dedicated spot is fixed. This is very disadvantageous for Japanese airports with limited land area. In addition, in order to remove the conventional PBB for large and medium-sized machines and introduce a new PBB exclusively for regional machines, there are disadvantages in terms of cost, such as new introduction of PBB and renovation of airport buildings. Therefore, if the PBB for conventional large and medium-sized aircraft can be used for regional aircraft, and all types of large-sized, medium-sized, and regional aircraft can be boarded with a single cab, the current airport There is no need to renovate the building and it can be installed directly, which is advantageous.

  A state in which the present invention is applied to a regional machine will be described with reference to FIGS. FIG. 1 is a view of an aircraft machine 51 as viewed from above when the PBB 1 in the present invention is joined to a regional aircraft 51. FIG. 2 is a view of the aircraft 51 of FIG. 1 as viewed from the front (arrow A). The PBB 1 in the present invention also includes a telescopic tunnel 2 and a cab 3 as in the prior art. The cab 3 is connected to the front end side of the tunnel. The tunnel 2 is positioned almost horizontally in the case of a large aircraft size, but when applied to a regional aircraft size, the tunnel 2 is inclined forward in accordance with the height of the entrance / exit of the aircraft 51 as shown in FIG. . The cab 3 is rotatably joined to the tunnel 2. A bellows 4 that extends upward is attached to the cab head that is the leading end side of the cab 3, and is joined to the aircraft 51 without damaging the outer wall of the aircraft 51, and serves as a rain guard for passengers and the like. The entrance / exit door 52 of the aircraft 51 rotates around its lower side and is opened, and in the fully opened state, the inner surface faces upward and the air steer 52 appears. From the cab 3, the raised floor 21 extends toward the uppermost stage of the air steer 52, thereby realizing barrier-free without a step with the floor surface in the aircraft 51.

  A cab 3 to which the present invention is applied and a PBB 1 to which the cab 3 is attached will be described with reference to FIGS. FIG. 3 is a view of the inside of the cab 3 to which the present invention is applied as viewed from above. In this specification, the opening width direction of the distal end side opening 3a means the direction X in FIG. The cab 3 has a front end side opening 3a which is the entrance / exit side of the aircraft 51 and a rear end side opening 3b which is the side of the expanding and contracting tunnel 2, and the rear end side opening 3b communicates with the tunnel 2 as a passage. To be joined. In the center of the cab 3, a circular main floor 10 is arranged. The wall portion of the cab 3 is configured by a large number of strip-shaped connecting members that can be wound around the main floor 10 by the winding device 11. The main floor 10 can be rotated around its central portion 10a in accordance with the direction of the front end side opening 3a of the cab 3 of the aircraft 51, and the wall portion 11 is wound and stored or extends accordingly.

  The front end side opening 3a of the cab 3 is defined by a front end floor 13 for a medium-sized machine as a first floor and a front end floor 17 for a regional machine as a second floor so as to be adjacent to the opening width direction of the front end opening 3a. The The medium machine front end floor 13 has a first width (L1), and the regional machine front end floor 17 has a second width (L2).

  The front end floor 13 for a medium-sized aircraft serving as the first floor is a floor for a medium-sized aircraft boarding space for boarding a medium-sized aircraft from the main floor 10 when the cab 3 is joined to the aircraft. When the cab 3 is joined to an aircraft, a cushion material such as rubber is attached to the front end floor 13 for a medium-sized aircraft on the side facing the aircraft. Both ends are defined in the opening direction of the front end side opening 3a of the cab 3 so that the width of the front end floor 13 for the medium size machine becomes a dimension L1 (first width) matched to the entrance / exit of the medium size machine. One end of the front end floor 13 for the medium-sized machine in the opening direction of the front end side opening 3 a is defined by the cab wall 14, and the other front end floor 13 for the middle-sized machine is defined by the end surface 13 a of the front end floor 13 for the middle-sized machine. Is done. Therefore, the width between the wall 14 and the end surface 13a of the front end floor 13 for a medium-sized machine is a boarding space for a medium-sized machine having a dimension L1 that matches the entrance / exit of the medium-sized machine. For example, the first width (L1) is 2400 millimeters for recent B737, DC-9, MD80, and A321 models. As will be described later, the auxiliary floor 16 is rotatably disposed on the lower side (back side) of the medium-sized machine front end floor 13 and defines a boarding space for a large machine in the unfolded state.

  In the opening width direction of the cab 3, the end surface 13 a of the front end floor 13 for the medium-sized machine is located in a direction substantially perpendicular to the front end face of the front-end floor 13 for the medium-sized machine in the front end opening 3 a. Extend. A second floor having a second width (L2) adjacent to the medium machine front end floor 13 on the side opposite to the medium machine front end floor 13 via the end surface 13a of the medium machine front end floor 13a. A leading end floor 17 for a barrel machine is arranged. The regional machine front end floor 17 is a floor of a regional machine boarding space for boarding the regional machine from the main floor 10. Since the width required for boarding the regional aircraft is narrower than that of the medium-sized aircraft, the first width (L1) is wider than the second width (L2). A partition 15 is arranged in the vicinity of the end surface 13a of the front end floor 13 for the medium-sized machine to isolate the boarding space for the medium-sized machine (dimension L1) from the boarding space for the regional machine (dimension L2). The passengers and the like are prevented from dropping from the front end floor 13 for the medium-sized aircraft when boarding the passengers or the like. The main floor 10 is partitioned, for example, by 18 or the like from the medium-sized machine front end floor 13 side. The main floor 10 is partitioned by a door 19 or the like from the regional machine end floor 17 side. For example, the support floor 9 is disposed on the main floor 10, and one end side of the shutter 18 is held, and if one end of the door 19 is pivotably joined by a hinge, an opening / closing structure can be formed. In the present embodiment, the partition 15, the column 9, and the door 19 are arranged so as to be substantially aligned along the end surface 13 a of the medium machine front floor 13, so that the boarding space for the medium machine (dimension L 1). And the boarding space for the regional machine (dimension L2) can be completely isolated. Further, the distal end of the regional machine front end floor 17 is disposed at a position retracted from the front end of the middle machine front end floor 13 in the direction of the rear end side opening 3b. When the front end floor 17 of the regional machine is made shorter in the direction of the rear end of the cab 3 than the front end of the front end floor 13 for the medium-sized machine, the boarding / exiting of the regional machine can be performed even when the entrance / exit door 52 rotates and opens. The door 52 does not interfere with the front end floor 17 for the regional machine.

[Regional boarding space]
With reference to FIG. 4 and FIG. 5, the boarding space for regional machines will be described. FIG. 4 is a view showing the vicinity of the end surface 13 a of the front end floor 13 for the medium-sized machine of the cab 3 from the front end side opening 3 a side of the cab 3. FIG. 5 is a view showing a side surface on the tip side. A storage space 19 is provided below the front end floor 17 for the regional machine, and a slide floor 20 is stored therein. The storage space 19 is a hollow space formed from the front end side opening 3a of the cab 3 toward the rear end side opening 3b, and is wide open in the opening direction of the front end side opening 3a. Thereby, the slide floor 20 can be extended so as to protrude toward the front end side of the cab 3 of the front end floor 17 for the regional machine, and is also movable in the opening width direction of the front end side opening 3a.

  A flip-up floor 21 is rotatably connected by a hinge 22 to the end of the slide floor 20 on the tip side opening 3 a side of the cab 3. A flip-up floor 21 can be rotated upward around the hinge 22 with respect to the slide floor 20. The slide floor 20 and the flip-up floor 21 constitute the stretchable floor 7, and the stretchable floor 7 can be extended so as to protrude in the direction of the front end side opening 3a of the cab 3, and the direction of the rear end side opening 3b. It can be shrunk. The stretchable floor 7 is also movable in the opening width direction of the front end side opening 3a. It is preferable that the width of the raised floor 21 substantially matches the step width of the air steer 52 of the regional machine. A handrail 21 a and a handrail 21 b are attached to the flip-up floor 21.

  A slide guide rail 24 is arranged on the regional machine front end floor 17 so as to extend along the width direction of the regional machine front end floor 17 (opening width direction of the opening 3a). For example, the slide guide rail 24 is arranged along the storage space 19 that is wide open at the end of the front end floor 17 for the regional machine above the storage space 19. A sliding member 26 that is elongated in the opening width direction of the regional machine front end floor 17 is attached to the slide guide rail 24. The sliding member 26 is attached so as to be slidable along the slide guide rail 24 in the width direction of the regional machine front end floor 17.

  A slope floor 23 is attached to the sliding member 26 by a hinge 26c. It is attached so that it can move along the opening width direction of the front end side opening 3a and can be flipped up from the stretchable floor 7. That is, the slope floor 23 is fixed so as to be rotatable around the hinge 26c so that the direction in which the slide guide rail 24 extends is the central axis. Usually, the slope floor 23 is attached so that the tip of the slope floor 23 is placed on the surface of the flip-up floor 21 of the stretchable floor 7. A means for driving the slope floor 23 is not attached, and the slope floor 23 rotates around the hinge 26 c by the movement of the flip-up floor 21. The flip-up floor 21 rotates, for example, by the expansion and contraction of the actuator rod of the actuator 21c disposed below the front end floor 17 for the regional machine. The flip-up floor 21 rises by the extension of the actuator rod of the actuator 21c and is positioned horizontally by the contraction.

  In the unfolded state where the tip of the slope floor 23 is placed in contact with the surface of the flip-up floor 21, the slope floor 23 has no step between the surface of the top floor 17 for the regional machine and the surface of the jump-up floor 21. A slope is formed from the machine tip floor 17 to the surface of the flip-up floor 21. In the retracted state of the stretchable floor 7, the flipped floor 21 is turned up according to the bending of the stretchable floor 7 so that the flipped floor 21 on the tip side of the stretchable floor 7 rotates upward around the hinge 22. 21 pushes up the slope floor 23. For example, the flip-up floor 21 rotates upward around the hinge 22 to about 60 degrees with respect to the slide floor 20. The slope floor 23 stops with its tip in contact with the flip-up floor 21.

  An engaging member is disposed on the back surface of the slope floor 23, and an engaging groove is disposed on the surface of the slide floor 20. The slope floor 23 is slid in a state where the tip of the slope floor 23 is placed on the surface of the raised floor 21. Engages with the floor 20. By this engagement, even if the stretchable floor 7 (the slide floor 20 and the flip-up floor 21) expands and contracts in the direction of the front end side opening 3a or the rear end side opening 3b, the slope floor 23 does not move, and the stretchable floor 7 When moving in the opening width direction of the front end side opening 3a, the slope floor moves together with the stretchable floor 7.

  Here, the engaging member and the engaging groove will be described. FIG. 6 is a view showing a cross section 6-6 of FIG. That is, for example, a roller 25 as an engaging member is fitted to the back surface of the slope floor 23. The roller 25 has a structure in which one end of the roller 25c is fixed to the back surface of the slope floor 23 and the rotating cylinder 25c is passed through the roller 25, and the rotating cylinder 25c is supported by a flange 25b disposed at the other end of the shaft 25a. Yes. On the upper surface of the slide floor 20, a guide groove 20 a that is an engagement groove is formed so as to extend along the expansion and contraction direction of the slide floor 20. The rotating cylinder 25c of the roller 25 can be contacted so as to roll into the guide groove 20a. When the slope floor 23 is deployed until it is placed on the surface of the flip-up floor 21, the roller 25 is inserted into the guide groove 20a. The roller 25 inserted into the guide groove 20a is movable along the guide groove 20a. In particular, since the roller 25 is slidable in the guide groove 20a, the slide floor 20 can be freely expanded and contracted from the storage space 19 without moving the slope floor 23 even when the slope floor 23 is expanded. .

  Further, in the state where the slope floor 23 is placed on the flip-up floor 21, the roller 25 as the engaging member is inserted into the guide groove 20a, so that the slide floor 20 is opened to the opening width of the front end side opening 3a. When moving in the direction, the sliding member 26 moves along the slide guide rail 22 in the width direction of the front end floor 17 for the regional machine, so that the slope floor 23 is moved together with the slide floor 20 and the raised floor 21 to the regional machine. It moves in the width direction of the front end floor 17 for use.

  In addition, the engagement member represented by the roller 25 should just be arrange | positioned at the expansion-contraction floor 7, and you may arrange | position not the slide floor 20 but the flip-up floor 21. FIG. The guide groove 20 a and the engaging member may be reversed, and the guide groove 20 a may be disposed on the slope floor 23 and the engaging member may be disposed on the slide floor 20 or the flip-up floor 21.

  Further, the engaging member may be not only the roller 25 but also a simple pin or a wheel structure that rotates about the axis of rotation perpendicular to the axis 25 a fixed to the back surface of the slope floor 23.

  Two gate post members 26 a and 26 b extending in a direction perpendicular to the front end floor 17 for the regional machine are disposed in the upper part near both ends of the sliding member 26. Between the gate pillar members 26a and 26b is a passage for passengers when boarding the regional machine 51 or the like. The distance between the gate pillar members 26 a and 26 b is wider than the width of the slope floor 23.

  On the front end floor 17 for the regional machine in the vicinity of the front end side opening 3a, support columns 27a and 27b are arranged on both sides of the front end side opening 3a in the opening width direction. Winding devices 29a and 29b for vinyl fabrics 28a and 28b as partition members are attached to the columns 27a and 27b, respectively. The vinyl fabrics 28a and 28b wound by the winding devices 29a and 29b are coupled to the gate post members 26a and 26b, respectively. Even if the sliding member 26 moves in the width direction of the front end floor 17 for the regional machine or the gate column members 26a and 26b move, the winding amount of the vinyl fabrics 28a and 28b is adjusted appropriately, and the gate column member 26a. , 26b is covered with vinyl fabrics 28a, 28b, and the passage of passengers or the like can be automatically adjusted only between the gate pillar members 26a, 26b. Further, a chain connecting the gate column members 26a, 26b and the columns 27a, 27b is attached to the position on the tip side of the cab 3 relative to the vinyl fabrics 28a, 28b so that passengers and the like do not fall.

  A retractable operation panel 30 is attached to the wall portion of the regional machine boarding space. At the time of operation, the retractable operation panel 30 rotates and expands to a position of a substantially horizontal one-dot chain line 30a.

[Boarding space for large and medium aircraft]
The front side of the front end floor 13 for medium-sized aircraft functions as a boarding passage. On the back side, which is the lower side of the front end floor 13 for the medium-sized machine, an auxiliary floor 31 disposed so as to be rotatable around the rotation axis in the direction along the end portion 13a of the front-end floor 13 for the medium-sized machine Has been placed. In the unfolded state, the auxiliary floor 31 rotates around its rotation axis, the end 13a of the intermediate floor 13 and the end of the auxiliary floor 31 are close to each other, and the front side of the intermediate floor 13 is located on the front side. And the auxiliary floor 31 form a surface having the same height. As a result, when the auxiliary floor 31 is deployed, the auxiliary floor 31 is positioned close to the medium-sized machine front floor 13, and thereby the third that is the sum of the width of the medium-sized machine front floor 13 and the width of the auxiliary floor 31. It is possible to form a leading end floor for a large machine having a width (L3).

  The auxiliary floor 31 will be described with reference to FIGS. 7 and 8. FIG. 7 is a view showing a cross section 7-7 of FIG. FIG. 8 is a view of the replenishment floor 31 as viewed from above the cab 3. An arm 32 protrudes from the end surface of the auxiliary floor 31. One end of the arm 32 is fitted with a shaft 33 arranged so as to be centered on a rotation shaft extending substantially perpendicular to the front end surface of the front end side opening 3a of the front end floor 13 for a medium-sized machine. The auxiliary floor 31 can be rotated around the rotation axis. A protrusion 13b and a protrusion 31a are disposed on the back surface of the front floor 13 for the medium-sized machine and the one surface of the auxiliary floor 31, respectively. A cylinder side end 34a of the actuator 34 is rotatably coupled to the protrusion 13b, and an actuator rod end 34b of the actuator 34 is rotatably coupled to the protrusion 31a. The cylinder side end 34a and the end 34b of the actuator rod 34c may be attached in reverse. The auxiliary floor 31 is rotated around the rotation axis by the arm 32 by the expansion and contraction of the actuator rod 34 c of the actuator 34. With the actuator rod 34c of the actuator 34 being most contracted, the auxiliary floor 31 is stored below the front end floor 13 for the medium-sized machine. As the actuator rod 34c of the actuator 34 extends, the auxiliary floor 31 is pushed up from the lower side of the medium machine front end floor 13 toward the end portion 13a of the medium machine front end floor 13 while changing its direction. The auxiliary floor 31 is set in an unfolded state at the same height as the surface of the medium machine front end floor 13 next to the end portion 13 a of the medium machine front end floor 13. At the stage of the unfolded state, the support plate 35 projects from the lower side of the end portion 13 a of the medium machine front end floor 13 toward the lower side of the auxiliary floor 31 to support the lower surface of the auxiliary floor 31.

  In the above example, the example in which the rotation of the auxiliary floor 31 is triggered by the expansion and contraction of the actuator rod of the actuator 34 has been described. However, the present invention is not limited to this method. For example, a gear (not shown) and a motor (not shown) may be combined. One of the gear and the motor may be attached to the front end floor 13 for the medium-sized machine, and the other may be attached to the auxiliary floor 31, and the rotation of the auxiliary floor 31 may be triggered by rotating the gear by driving the motor.

  In addition, the partition 15 arranged on the end surface 13a of the front end floor 13 for the medium-sized machine is configured to be divided into a first partition 15a on the front end side opening 3a side and a second partition 15b. The first partition 15a and the second partition 15b are rotatably coupled to the first partition 15a by a hinge 15c so that the second partition 15b changes its angle. The 2nd partition 15b and the support | pillar 9 are couple | bonded with the support | pillar 9 with the hinge 15d so that the angle of the 2nd partition 15b may change. When the auxiliary floor 31 is unfolded next to the end portion 13a of the medium-sized machine front end floor 13, the second partition 15b is moved along the end portion 31b of the auxiliary floor 31 by the hinge 15d. Translate to rotate around column 9 until positioned. As the partition 15 moves, the boarding space is changed to a large machine boarding space.

  The partition 15 is at any one of the first position where the partition 15 is located along the end surface 13a of the intermediate floor 13 and the second position where the partition 15 is located along the end surface 31b of the auxiliary floor 31. In order to fix so that it may not move, the fixing pin 44 which can be raised / lowered is arrange | positioned at the side surface of the 1st partition 15a. Holes are respectively arranged in the front end floor 13 for the medium-sized machine at the position of the fixing pin 44 corresponding to the first position and the auxiliary floor 31 at the position of the fixing pin 44 corresponding to the second position. The fixing pin 44 is dropped into the holes at the first position and the second position, and the partition 15a is fixed at each position. An iron blind plate 37 is placed in the hole on the side where the partition 15 is not located. FIG. 9 is a diagram showing, as an example, the hole 31a in the cross section 9-9 in FIG. 8 at the second position. The same applies to the first position. The blind plate 37 is, for example, a rectangular iron plate. The medium-sized machine front end floor 13 and the auxiliary floor 31 have escape portions that are thick enough to accommodate the blind plate iron 37. The blind plate 37 is removed by a magnetic force by a removal tool 38 with a dedicated magnet 38a attached thereto and pulled up from the escape portion.

  The tip on the tip side opening 3a side of the partition 15 at the first position is located in front of the tip side opening 3a in the second position. Even when the auxiliary floor 31 is in the unfolded state, the interior of the cab 3 is isolated from the outside by the partition 15 as far as the tip of the partition 15 at the tip side opening 3a side at the second position is allowed in the front of the tip side opening 3a. Accordingly, when the cab 3 is brought close to the aircraft, the tip of the partition 15 at the first position on the tip side opening 3a side may interfere with the outer surface of the aircraft. FIG. 10 is a diagram showing the mechanism of the partition 15 and the partition plates 41a and 41b. The inside of the first partition 15a is hollow, and the slide part 40 is inserted therein. A moving bar 43 is arranged on the side surface of the slide part 40 and protrudes from the side surface of the first partition 15a. By the moving bar 43, the slide part 40 is movable in the direction of the arrow in FIG. 10 between the front end side and the rear end side inside the first partition 15a. When in the first position, the slide portion 40 is disposed on the rear end side of the first partition 15a, and when in the second position, the slide portion 40 is disposed on the front end side of the first partition 15a and locked at each position. Is possible. When the partition 15 is in the second position, the tip of the partition 15 is retracted more than when the partition 15 is in the first position. However, when the partition 15 is in the second position, the slide portion 40 is moved to the tip side of the first partition 15a. Thus, even if the tip of the partition 15 is retracted, the slide portion 40 extends from the inside of the first partition 15a as much as the retracted length, thereby complementing the length of the retracted portion.

  Partition plates 41a and 41b are supported to be swingable around the pivots 39a and 39b at corners (corners that do not face each other) above or below the tip side of the slide part 40, respectively. When an external force is applied to the partition plates 41a and 41b, the partition plates 41a and 41b can be pushed into the first partition 15a.

  The partition plates 41a and 41b are urged so as to extend from the first partition 15a to the distal end side of the first partition 15a on the distal end side opening 3a side. In other words, the opposing corners of the partition plates 41 a and 41 b inserted into the partition 15 are urged so as to be coupled and attracted by the spring 42. Thereby, when external force is not applied to the partition plates 41a and 41b, for example, when the partition 15 is in the second position, the partition plates 41a and 41b extend from the partition 15 to the distal end side on the distal end side opening 3a side of the partition 15. . On the other hand, when the partition 15 is in the first position and the cab 3 is in contact with the aircraft 51 and the wall surface of the aircraft 51 interferes with the partition plates 41a and 41b, the partition wall 41a, An external force is applied to 41 b, and the partition plates 41 a and 41 b are pushed into the partition 15. The partition walls 41a and 41b are retracted so that the aircraft wall is not damaged. On the other hand, when the cab 3 is retracted from the aircraft, the partition plates 41a and 41b are returned to their original positions by the urging force.

  Subsequently, the use of the cab 3 in this embodiment will be described with reference to FIGS. 3, 11, and 12. 11 shows the cab 3 when boarding a medium-sized machine, FIG. 3 shows the cab 3 when boarding a regional machine, etc., and FIG. 12 is when boarding a large machine, etc. The cab 3 is shown.

  First, when boarding a medium-sized machine or the like, a boarding space for medium-sized machines (dimension L1) in the cab 3 is used as shown by an arrow in FIG. The partition 15 is in the first position, and passengers or the like board the vehicle using the front end floor 13 for medium-sized aircraft. The boarding space for the regional machine (dimension L2) is not used, the slope floor 23 is flipped up, the slide floor 20 is stored in the storage space 19, and the flip-up floor 21 is flipped up. The door 19 to the boarding space for the regional aircraft is closed, and passengers enter the boarding space for the medium-sized aircraft with the shutter 18 raised.

  When boarding a regional aircraft, etc., as shown by the arrows in FIG. 3, the passengers etc. travel through the regional aircraft boarding space (dimension L2). The partition 15 is in the first position, and the passengers use the regional machine tip floor 17 to board and the like. The boarding space for medium-sized aircraft (dimension L1) is not used. The raised floor 21 in the stored state is developed in the horizontal direction, and the slide floor 20 is pulled out from the storage space 19. The slope floor 23 is developed so as to be placed on the flip-up floor. Passengers and the like enter the boarding space for the regional machine through the door 19 to the boarding space for the regional machine. The retractable operation panel 30 is in the unfolded state 31a, and the retractable operation panel 30 performs the deployment and storage of the slope floor 23 and the operation of the cab 3. The shutters 18 in the boarding space for the medium-sized aircraft and the boarding space for the large aircraft are closed.

  When boarding a large machine, etc., as shown by the arrow in FIG. 12, the passengers, etc. go through the boarding space for large machines having a large machine front floor of dimension L3 (third width). Do. The third width L3 is defined as the sum of the width of the intermediate floor tip 17 and the width of the auxiliary floor 31 when the auxiliary floor 31 comes close to the intermediate floor tip 17 in the expanded state of the auxiliary floor 31. Width. Since the boarding space for the regional machine (dimension L2) is not used, the telescopic floor 7 (the flip-up floor 21 and the slide floor 20) moves together with the slope floor 23 in the opening width direction of the front end side opening 3a of the cab 3. The auxiliary floor 31 is set in an unfolded state in the space between the medium-sized machine front-end floor 13 and the stretchable floor 7 vacated by the movement of the stretchable floor 7. The partition 15 moves to the second position. Passengers and the like board the vehicle using the front floor 13 for the medium-sized aircraft and the auxiliary floor 31 in the deployed state. The door 19 to the regional boarding space is closed, and passengers enter the boarding space for the large aircraft with the shutter 18 raised.

  Further, in the cab 3 corresponding to all kinds of large-sized / medium-sized machines and regional machines, as shown in FIG. 2, when the bellows 4 is connected to the aircraft 51, the large-sized / medium-sized machines, The expansion of the bellows 4 to match the regional machine is required. The extension of the cab 3 for conventional large and medium-sized machines does not reach the regional machine. It is necessary to match each of large, medium and regional machines.

  FIG. 13 shows a bellows structure that can be adapted to each of a large machine, a medium machine, and a regional machine. In this structure, the second bellows 55 is further joined to the tip end side of the first bellows 4 directly attached to the cab 3. The second bellows 55 is supported by the second bellows support structure 55a so as to be extendable and contractible. A guide rail 56 extending along the direction in which the bellows 4 extends is disposed on the side of the first bellows 4. The second bellows 55 support structure 55a extends to the tip side of the cab 3 with respect to the first bellows 4 along the guide rail 56 regardless of the expansion and contraction of the second bellows 55. For example, the support structure of the second bellows 55 is moved by the extension of the actuator rod 55c of the actuator 55b disposed below the first bellows 4. The second bellows support structure 55 a has a link structure 57 inside the second bellows 55 from the position where the second bellows support structure 55 a is produced on the most distal end side according to the guide rail 56. One end of the link structure 57 is pivotally attached to the support structure of the second bellows 55 as a fulcrum. On the other hand, the other end side of the link structure 57 is attached to the opening frame at the tip of the second bellows 55 as an action point. As a result, the link structure 57 is inclined at the other end side of the link structure 57 around the one end side, and the second bellows 55 extends relative to the second bellows support structure 55a. For example, when the link structure 56 is tilted from the position where the first bellows 4 is fully extended, the second bellows 55 is moved relative to the second bellows support structure 55a so that the amount of extension on the upper side of the second bellows 55 becomes particularly large. Stretch. One end of the link structure 57 as a fulcrum is preferably disposed approximately from the middle to the lower side of the second bellows 55 in the cab height direction. Thereby, the length of a fulcrum and an action point can be lengthened, and the extension amount of the 2nd bellows 55 can be enlarged. Conversely, if one end of the link structure 57 as a fulcrum is positioned above the second bellows 55 in the height direction, the length of the fulcrum and the action point is shortened, and the extension amount of the second bellows 55 can be reduced. . As described above, the ratio of the upper extension amount and the lower extension amount of the second bellows 55 can be adjusted by changing the position height of the fulcrum of the link structure 57.
