Description

[Technical Field]

[0001] The present invention relates to an access device, and more particularly to an access device for a cockpit of a simulator. [Background technology]

[0002] As an example of a conventional simulator, for example, a driving simulator described in Patent Document 1 uses a servo cylinder to change the posture of a simulated vehicle body relative to the floor. By combining this change in posture of the simulated vehicle body (cockpit) relative to the floor with an image projected onto a screen by a projector, it is possible to simulate the situation in which a driver inside the simulated vehicle body is driving a car.

[0003] In this simulator, passengers enter and exit the cockpit via a boarding / exiting device such as a bridge that is arranged so as to avoid actuators such as servo cylinders that are provided on the floor. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 4493575 Summary of the Invention [Problem to be solved by the invention]

[0005] It is preferable that a driving simulator be compatible with both right-hand drive and left-hand drive cockpits. In this case, if the entrance / exit device is provided for a right-hand drive cockpit, it will be difficult for a left-hand drive driver to get in and out of the cockpit. For example, the driver will have to move through a relatively narrow cockpit to reach the seat with the left-hand drive. To address this issue, it is conceivable to use two entrance / exit devices, but this would result in problems such as increased costs.

[0006] Therefore, an object of the present invention is to provide a single boarding / alighting device that can be used for the different boarding / alighting entrances on the left and right sides of the cockpit of a simulator, and that allows boarding and alighting from either entrance. [Means for solving the problem]

[0007] In order to solve the above problem, a boarding and alighting device for boarding and alighting from a mobile simulator having a cockpit with boarding and alighting doors is provided, which is characterized by comprising: a bridge for boarding and alighting; a platform to which the bridge is movably attached; and a movement mechanism for moving the bridge relative to the platform and positioning the bridge in correspondence with one or the other of the boarding and alighting doors of the cockpit.

[0008] In addition, the bridge of the boarding / exiting device may further include an extension / contraction mechanism.

[0009] The boarding / alighting device may have two boarding / alighting doors, one on the left and one on the right side of the cockpit.

[0010] In addition, in the above-mentioned getting-on / off device, the movement mechanism may include a trapezoidal screw for left-right movement.

[0011] In addition, in the above-mentioned boarding / exiting device, the movement mechanism may include a left / right movement motor and a left / right movement trapezoidal screw.

[0012] In addition, the boarding and alighting device may be configured so that passengers can board and alight from the left and right doors of the cockpit by switching the safety fences at the tip of the bridge and near the tip.

[0013] In addition, the boarding / exiting device may be such that the bridge includes a plurality of bridges, and the telescopic mechanism is a mechanism in which the plurality of bridges are stored in a nested structure with each other and extend and deploy relative to each other when in use.

[0014] In addition, in the above-mentioned boarding and disembarking device, the telescopic mechanism may further include a ball screw and a linear guide.

[0015] In addition, the telescopic mechanism of the boarding / alighting device may be a pop-up bridge.

[0016] In addition, the telescopic mechanism of the boarding / alighting device may be a rotating bridge.

[0017] In addition, the bridge structure of the boarding / exiting device may be a truss structure. [Effects of the Invention]

[0018] According to the present invention, a single boarding / alighting device can be used to accommodate the different boarding / alighting doors on the left and right sides of the simulator cockpit, allowing passengers to board and alight from either door. [Brief explanation of the drawings]

[0020] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0021] FIG. 1 is a perspective view showing the configuration of a driving simulator 100 according to one embodiment of the present invention.

[0022] As shown in FIG. 1, the driving simulator 100 is configured to include a cockpit 110, an actuator system 120 that operates the cockpit, a screen 130 that displays the scenery seen from the cockpit in response to the operation of the cockpit, a boarding bridge 140 that is an access point for the cockpit 110, a platform 150 that is provided with the access point and on which the driver gets on and off, and a recessed pit 160 (see FIG. 3(b)) on which the actuator system 120 is disposed and that has a bottom surface (floor surface) that is lower than the platform 150. The platform 150 includes a base 180 for fixing the boarding bridge 140. The base 180 includes a left-right movement mechanism 190 that is a movement mechanism for moving the boarding bridge 140 to the left and right of the base 180. That is, in this embodiment, two cockpits, one for a right-hand drive vehicle and one for a left-hand drive vehicle, are used as the cockpit 110, and are interchangeable as needed (FIG. 1 shows the right-hand drive vehicle). At this time, the left-right movement mechanism 190, as will be described in detail later, moves the boarding bridge 140 to the left or right of the base 180 depending on whether the cockpit 110 has a right-hand drive or a left-hand drive, to align it with the entrance and exit of the cockpit 110. Note that although this embodiment relates to a simulator for an automobile as the driving simulator 100, it is not limited thereto. For example, it will be clear from the following description that the driving simulator 100 can also be a simulator for a moving body such as a railroad car or an airplane. Also, in this embodiment, the driving simulator 100 is described as having a pit 160, but this is not limited thereto. For example, the pit 160 may not be provided, and only the platform may be raised to a high position above the floor to match the position of the cockpit.

[0023] The cockpit 110 (FIG. 1 shows a right-hand drive vehicle) is a boarding area where a driver boards to simulate driving, and is equipped with components for driving that mimic an actual automobile, such as a steering wheel, a seat, an instrument panel, side mirrors, a right door 115, and a left door 116. The cockpit 110 also has multiple entrances and exits. In this embodiment, the cockpit 110 has a right entrance 110a and a left entrance 110b corresponding to the right door 115 and the left door 116, respectively. A boarding bridge (boarding and exiting device) 140, through which the driver gets on and off the cockpit 110, is provided on the platform 150. As will be described in detail later, when the driver gets on and off the boarding bridge 140, the boarding bridge 140 extends as a whole, with its tip positioned corresponding to the right entrance 110a of the cockpit 110 (FIG. 1 shows this state). In this state, a pair of support legs 172 provided on the underside of the tip of the boarding bridge 140 extend into a pit 160 in which the actuator system 120 is provided and contact the floor of the pit. As a result, the tip of the boarding bridge 140 is supported by the support legs 172. When a simulation is not being performed, the boarding bridge 140 is retracted as a whole as the support legs 172 are retracted, and is positioned above the platform 150 (see FIG. 4A(a)). That is, when using the driving simulator 100, the boarding bridge 140 is first extended so that its tip corresponds to the position corresponding to the right boarding / alighting door 110a of the cockpit 110. Next, the driver opens the entrance door 142 on the front side of the boarding bridge 140 on the platform 150, gets on the boarding bridge, walks along the safety fence 146 to the boarding / alighting opening 141a, and enters the cockpit 110 through this opening. After using the driving simulator 100, the driver transfers from the cockpit 110 to the boarding bridge 140 through the boarding opening 141a at the tip of the boarding bridge 140, in the reverse order of the above, and moves to the platform 150 through the entrance door 142 on the platform 150 side of the boarding bridge 140. Thereafter, the boarding bridge 140 is contracted and put into a stored state.

[0024] 2(a) and 2(b) are schematic plan views showing the different cockpit stopping positions when the cockpit 110 has a right-hand drive and when it has a left-hand drive, and the positional relationship between the boarding bridge 140 and the cockpit 110. These cockpit stopping positions are positions where the driver gets on and off during the simulation.

[0025] 2(a), when the cockpit 110 has a right-hand drive, the cockpit 110 stops at a stopping position that is on the right side of the center line L1 in a plan view of the base 180. At this time, the boarding bridge 140 is positioned on the right side of the base 180 so as to correspond to the stopping position of the cockpit 110 with a right-hand drive.

[0026] 2(b), when the cockpit 110 is a left-hand drive aircraft, the cockpit 110 stops at a stopping position on the left side of the center line L1 in a plan view of the base 180. At this time, the boarding bridge 140 is positioned on the left side of the base 180 so as to correspond to the stopping position of the cockpit 110 with a left-hand drive.

[0027] In this embodiment, the cockpit 110 stops at different positions depending on whether the steering wheel is right-hand or left-hand. Therefore, in order to accommodate the different stopping positions of the cockpit 110 with a single boarding bridge 140, as described above, the base 180 is provided with a left-right movement mechanism 190, which will be described later.

[0028] 3(a) and 3(b) are an enlarged plan view and an enlarged side view, respectively, showing the positional relationship between the boarding bridge 140 corresponding to the right boarding / alighting door 110a shown in FIG. 1 and the cockpit 110. FIG.

[0029] As shown in FIG. 3( a), the boarding bridge 140 is extended from the platform 150 until its tip reaches a position adjacent to the cockpit 110. At this time, the boarding bridge 140 extends toward the cockpit 110, which is stopped at a predetermined stopping position, but does not come into contact with the cockpit 110. Then, the right door 115 of the cockpit 110 opens toward the boarding and disembarking opening 141a at the tip of the boarding bridge 140, ensuring a path for the driver to board and disembark from the boarding bridge 140 to the cockpit 110. Furthermore, because the boarding bridge 140 does not come into contact with the cockpit 110, the weight of the boarding bridge 140 and the impact caused by extension and contraction are not applied to the cockpit 110, and there is no effect on the cockpit 110, the actuator system 120 (described later), etc. In the case of a boarding bridge 140 that is compatible with a left-hand drive vehicle, the left door 116 of the cockpit 110 opens toward the boarding opening 141b at the tip of the boarding bridge 140.

[0030] 3(b), when the boarding bridge 140 is extended, the bottom of the boarding bridge 140 and the bottom of the cockpit 110 are configured to be at the same height. In this way, even if the height from the floor on which the actuator system 120 of the cockpit 110 is provided to the cockpit 110 is relatively high, by using the boarding bridge 140 of this embodiment, the boarding bridge 140 can be easily installed and removed from the cockpit 110. Furthermore, since the driver can get on and off the cockpit 110 by walking on the boarding bridge 140, the driver can move in the same way as in an actual vehicle where the driver walks on the ground to get on, and a high sense of immersion can be achieved.

[0031] 1 and 3(b), the actuator system 120 includes three actuators 121a, 121b, and 121c that are evenly spaced apart at three locations along the circumferential direction so as to surround the periphery of the cockpit 110. These three actuators can partially contract in their respective axial directions and are connected to an oscillating base 111, which is fixed to a cockpit support base provided on the bottom side of the cockpit 110, via a hexapod 124. The hexapod 124 is fixed to a base plate 126. This allows the actuator system 120 to drive the actuators 121a, 121b, and 121c using a driving source such as hydraulic pressure, thereby moving the cockpit 110 in two axial directions, X and Y. The hexapod 124 also allows the cockpit 110 to move with six degrees of freedom, i.e., in the three axial directions, X, Y, and Z, and in rotational directions around each of these axes. The operation of the cockpit by these actuators 121a, 121b, 121c and hexapod 124 is controlled by a host computer (not shown).

[0032] Screen 130 is installed above pit 160, surrounding cockpit 110, and images are projected onto it by a projector (not shown) suspended from the ceiling. Screen 130 is located at a predetermined height above the floor of the pit to avoid the drive sources and hydraulic pipes of actuators 121a, 121b, and 121c, which are installed on the floor of pit 160.

[0033] When the projector receives image signals from a computer (not shown), it projects simulated images, which are images of the scenery that would be seen from inside the vehicle if the vehicle were to travel on a simulated road in accordance with each image signal, onto the screen 130. The driver obtains information about the road, signs, traffic lights, other vehicles, pedestrians, etc. while looking at the simulated images projected onto the screen 130, and performs driving operations in accordance with that information.

[0034] Here, drive mechanisms such as the three actuators 121a, 121b, and 121c and the hexapod 124 are provided, and particularly when the actuator of the hexapod 124 has a relatively long stroke, the height of the cockpit 110 provided above the hexapod 124 becomes relatively high. Therefore, in this embodiment, the drive mechanisms are provided in a pit that is a recessed portion relative to the platform 150. Furthermore, since a pit is provided, passengers get on and off the cockpit 110 using a boarding bridge 140, and the boarding bridge 140 provided on the platform is configured to extend and retract relative to the cockpit 110.

[0035] The platform 150 is a platform for the driver to enter the room where the driving simulator 100 is installed and to board onto the top of the boarding bridge 140. The platform 150 is made of, for example, concrete and has a horizontal floor surface on top. The platform 150 also has the above-mentioned pit 160 in the center.

[0036] The boarding bridge 140 is attached to and fixed to the platform 150 via a base 180. The base 180 is fixed by being embedded into the platform 150 when the concrete that makes up the platform 150 is laid. The base 180 is also supported on the floor of the pit 160 by fixing legs 181.

[0037] The base 180 is equipped with a left-right movement mechanism 190, which moves the boarding bridge 140 so that it corresponds to the right boarding / alighting entrance 110a and the left boarding / alighting entrance 110b, which differ depending on whether the cockpit 110 is right-hand drive or left-hand drive, as will be described in detail later.

[0038] 4A(a), (b), and 4B(c) are diagrams illustrating the boarding bridge 140 corresponding to the right boarding / alighting entrance 110a according to this embodiment. Note that the boarding bridge 140 corresponding to the left boarding / alighting entrance 110b has a different configuration of the tip and boarding / alighting opening from the boarding bridge 140 corresponding to the right boarding / alighting entrance 110a, and is also positioned differently on the base 180, as will be described in detail later.

[0039] FIG. 4A(a) is a perspective view showing a retracted state of the boarding bridge 140 corresponding to the right boarding / alighting entrance 110a according to an embodiment of the present invention. In this embodiment, the boarding bridge 140 includes a bridge 143, which is a structure of a series of rectangular frames that also serve as a safety fence 146. The bridge 143 includes multiple bridges, including a first bridge 143a that is fixed to the platform 150, a second bridge 143b that is the middle portion, and a third bridge 143c that is the tip portion. The bridges also include an extension / contraction mechanism that allows the first bridge 143a, the second bridge 143b, and the third bridge 143c to extend and unfold relative to each other and, conversely, to contract and retract relative to each other when in use. The first bridge 143a of the boarding bridge 140 is fixed to a base 180, which is a fixed base for fixing the boarding bridge 140 to the platform 150. When the boarding bridge 140 is in the stored state, the first bridge 143a, the second bridge 143b, and the third bridge 143c are nested within one another and contracted by the telescoping mechanism, and are stored together on the base 180. The bridge 143 may have, for example, a truss structure. If the bridge 143 has a truss structure, the rigidity of the bridge 143 can be sufficiently ensured during telescoping and after extension and deployment, and telescoping of the bridge 143 and the support legs 172, which will be described later, will not be hindered. In this embodiment, the bridge 143 is composed of multiple bridges, i.e., three bridges, but this is not limited to this and the bridge 143 may be composed of, for example, two bridges, four bridges, or five or more bridges.

[0040] 4A(b) is a perspective view showing a state in the middle of deployment when the boarding bridge 140 corresponding to the right boarding / alighting entrance 110a according to the embodiment of the present invention is in use. From the stored state described above, the first telescoping motor 148a, which is a drive device for driving the telescoping mechanism, is used to rotate the first telescoping ball screw 148b, which is a telescoping mechanism, so that the third bridge 143c extends and deploys toward the cockpit 110 relative to the first bridge 143a along the first telescoping linear guide 148c, which is a telescoping mechanism. At the same time, the second telescoping motor 149a is used to rotate the second telescoping ball screw 149b, so that the second bridge 143b extends and deploys toward the cockpit 110 relative to the first bridge 143a along the second telescoping linear guide 149c. As described above, the telescoping mechanism is configured using a ball screw, which allows for a faster extension / retraction speed than when other screws are used. As mentioned above, the boarding bridge 140 has a nested structure in which the first bridge 143a, the second bridge 143b, and the third bridge 143c move and expand relative to one another. This allows the boarding bridge 140 to expand only in the direction of the cockpit 110, preventing collisions with the cockpit 110, the screen 130, and other peripheral equipment. Because of this nested structure, the number of parts is smaller and simpler than when the bridge expands and contracts using a bellows or pantograph system, and furthermore, safety fences can be easily attached.

[0041] 4B(c) is a perspective view showing the fully deployed boarding bridge 140 corresponding to the right boarding / alighting entrance 110a in an embodiment of the present invention. The second bridge 143b and the third bridge 143c are fully deployed in the extension direction relative to the first bridge 143a. In this state, as will be described below, the support legs 172 of the tension jack 170 extend from the storage section 171 toward the floor surface of the pit 160 to support the tip of the boarding bridge 140.

[0042] When the driving simulator 100 is in use, the boarding bridge 140 is retracted and stored toward the platform 150 in the reverse order to the procedure in which the boarding bridge 140 extends and unfolds toward the cockpit 110. The boarding bridge 140 corresponding to the left boarding / alighting entrance 110b also extends and retracts in the same order as described above.

[0043] In this embodiment, the boarding bridges 140 are stored in a nested structure, but this is not limiting. A boarding bridge having a bridge with a length equal to the distance from the platform 150 to the cockpit 110 may be a lift-up bridge that is lifted up and positioned above the platform 150 to become stationary. Alternatively, instead of being lifted up, the boarding bridge may be a rotating bridge that rotates toward the platform 150 so that its tip traces an arc in a plan view and becomes stationary. Alternatively, a bridge with an integrated structure may be configured to move directly to the vicinity of the cockpit 110 and then return directly to the platform 150.

[0044] In this way, the boarding bridge 140 is stored in a nested structure and deployed in the extension direction. Furthermore, the boarding bridge 140 has the support legs 172 as described above at its tip. This allows the boarding bridge 140 to extend to the cockpit 110 without being obstructed by the actuators 121a, 121b, 121c or hydraulic pipes that run along the floor of the pit 160. Therefore, the boarding bridge 140 can be attached to and detached from the cockpit 110 regardless of the condition of the floor on which the driving simulator is installed.

[0045] Furthermore, as described above, if the boarding bridge is stored by a flip-up or rotating mechanism, it is not necessary to make the bridge portion of the boarding bridge a nested structure, and the boarding bridge can be extended to the cockpit 110 with a simple mechanism. The same effect can also be obtained when the integrated bridge itself moves directly to the vicinity of the cockpit 110 and returns directly to the platform 150.

[0046] <Tension jack> 5(a) and 5(b) are enlarged perspective views showing details of the tension jack 170 of the boarding bridge 140 according to the embodiment of the present invention.

[0047] FIG. 5(a) is an enlarged perspective view showing a state in which the support leg 172 of the tension jack 170, which is an extendable support device for the boarding bridge 140, is stored in the storage section 171. As described above, the support leg 172 remains stored in the storage section 171 until the boarding bridge 140 is fully deployed. The support leg 172 has a leg section 172a formed by a ball screw. A jack motor 173 is attached to a drive shaft 174 for extending and retracting the support leg 172 via a gear (not shown). As a result, when the jack motor 173 is not rotating, the frictional force between the leg section 172a and the storage section 171 and the frictional force between the gear of the jack motor 173 and the drive shaft 174 allows the support leg 172 to remain stationary relative to the storage section 171. Note that the jack motor 173 may be kept energized, and the holding torque of the jack motor 173 may be used to maintain the stationary state.

[0048] FIG. 5(b) is an enlarged perspective view showing the state in which the support leg 172 extends and reaches the floor of the pit 160 from the storage section 171. When the boarding bridge 140 is deployed, the jack motor 173 rotates from the stationary state described above, and driving force is transmitted through the gear, drive shaft 174, and leg 172a. As a result, the support leg 172, which is a ball screw, extends from the storage section 171 to the floor of the pit. The support leg 172 has a foot 172b, and when the foot 172b touches the floor of the pit, the jack motor 173 stops rotating. Due to the meshing friction between the leg 172a, which is a ball screw, and the storage section 171, which has a female thread corresponding to the ball screw, the support leg 172 remains stationary relative to the storage section 171. Thus, the boarding bridge 140 is supported by the support leg 172. As a result, the free end of the boarding bridge 140, which is a cantilever beam, is supported and fixed at its tip, preventing the boarding bridge 140 from bending or twisting, and allowing the driver to safely approach the cockpit 110 using the boarding bridge 140 and board safely. Furthermore, since the leg 172a is made of a ball screw, the leg 172a can quickly respond to the rotation of the jack motor 173 and quickly extend and retract. As described above, the jack motor 173 may be kept energized, and the holding torque of the jack motor 173 may be used to hold the extended support leg 172.

[0049] As described above, in this embodiment, the tension jack 170 is used, which has support legs 172 that are ball screws, but the support legs are not limited to this. For example, trapezoidal screws or worm gears can also be used. The support device may also have foldable support legs that are folded when stored. The tension jack 170 may also be a hydraulic jack. Even when such a support device is used, the support legs can be quickly extended and retracted.

[0050] <Boarding bridge left / right movement mechanism> Fig. 6(a) is a schematic plan view showing the right boarding / alighting entrance 110a of the cockpit 110 according to an embodiment of the present invention, i.e., a boarding bridge at a position corresponding to the right handle, Fig. 6(b) is an enlarged perspective view showing the tip of the boarding bridge shown in Fig. 6(a), and Fig. 6(c) is an enlarged perspective view showing a mechanism for moving the boarding bridge left and right, showing the state before the boarding bridge has moved to the left. Note that "left" and "right" here refer to the left and right sides, respectively, of the center line L1 of the base 180 in Figs. 2(a) and 2(b).

[0051] 6(a), when the cockpit 110 has a right-hand drive, the boarding opening 141a of the boarding bridge 140 opens to the left side in a plan view of the third bridge 143c. This allows the driver to get in and out of the cockpit 110 using the boarding opening 141a and the right boarding / alighting door 110a that opens on the right side of the cockpit 110.

[0052] The boarding bridge 140 is equipped at its tip with a tension jack displacement plate 144. This tension jack displacement plate 144 allows the tension jack 170 to rotate within a plane including the tension jack displacement plate 144, and the support legs 172 of the tension jack 170 can touch the floor of the pit 160 while avoiding actuators, hydraulic pipes, and the like that crawl on the floor of the pit 160.

[0053] 6(b), when the cockpit 110 is a right-hand drive vehicle, the right side of the tip safety fence 146a is lower than the left side when viewed from the front in order to avoid the right side mirror of the cockpit 110. In addition, the opening closing safety fence 146b is fitted to the right side of the third bridge 143c, and the boarding / alighting opening 141a is open on the left side of the third bridge 143c.

[0054] As shown in Figure 6(c), the boarding bridge 140 is provided with a boarding bridge left-right movement mechanism 190 on the entrance door 142 side. The left-right movement mechanism 190 is composed of a left-right movement handle 191 for moving the boarding bridge 140, a left-right movement trapezoidal screw 192 for sending the boarding bridge 140 to either the left or right, and a left-right movement linear guide 193 that serves as a guide when the boarding bridge 140 moves left and right on the platform 150. A more detailed configuration will be explained in the following section, with reference to Figures 7(a) and (b).

[0055] When the boarding bridge 140 is handed over to the cockpit 110 for a right-hand drive aircraft, the boarding bridge 140 is positioned on the right side on the base 180.

[0056] Here, when the cockpit 110 is converted to one compatible with left-hand drive and passengers board or disembark from the cockpit 110 through the left boarding / alighting door 110b on the left side of the cockpit 110, the boarding bridge 140 is moved to the left side of the base 180 using the left / right movement mechanism 190.

[0057] Fig. 7(a) is an enlarged perspective view showing the detailed configuration of the left-right movement mechanism 190 according to the embodiment of the present invention, showing the state after the boarding bridge 140 has moved to the left. Fig. 7(b) is an enlarged cross-sectional view showing the details of the mechanism of the left-right movement mechanism 190 according to the embodiment of the present invention.

[0058] As shown in FIG. 7( a), left-right movement mechanism 190 includes a manual clamp 194 between left-right movement handle 191 and left-right movement ball screw 192 that is tightened to fix rotation shaft 195 after the bridge has been moved, rotation shaft 195 that transmits the rotation of left-right movement handle 191 to miter gear 196 below, and miter gear 196 that converts the rotation of left-right movement handle 191 into a perpendicular direction and converts it into rotation of left-right movement trapezoidal screw 192.

[0059] 7(b), the trapezoidal screw 192 for left-right movement includes a left stopper 197a, a right stopper 197b, and a nut 198 for positioning by bringing the nut 198 of the trapezoidal screw 192 for left-right movement into contact with a connecting part 199 of the boarding bridge 140. The trapezoidal screw 192 for left-right movement is engaged with the boarding bridge 140 via the connecting part 199. Thus, the left-right movement mechanism 190 includes, in addition to the above-described configuration, a manual clamp 194, a rotating shaft 195, a miter gear 196, a left stopper 197a, a right stopper 197b, a nut 198, and a connecting part 199.

[0060] The left-right movement handle 191 is rotated, for example, manually counterclockwise, thereby rotating the rotary shaft 195, and the miter gear 196 converts this rotation into a rotation in the perpendicular direction, causing the left-right movement trapezoidal screw 192 to rotate, and the boarding bridge 140, which is engaged with the trapezoidal screw 192 by the connecting part 199, moves to the left side of the base 180 along the left-right movement linear guide 193. At this time, the connecting part 199 hits the left stopper 197a, and the boarding bridge 140 stops. After the movement of the boarding bridge 140 has stopped, the manual clamp 194 is tightened to fix the rotary shaft 195. This prevents the boarding bridge 140 from moving left or right.

[0061] Note that by manually rotating the left-right movement handle 191, the boarding bridge 140 can be moved to the left of the base 180, thereby achieving left-right movement of the platform 150 with a simple configuration. In addition, the use of a trapezoidal screw allows for lower costs compared to using a ball screw. Furthermore, compared to using a triangular screw, the frictional force is lower and the feed pitch is smaller, so the left-right movement handle 191 can be turned manually with less force. However, the rotation of the left-right movement handle 191 is not limited to manual operation; the boarding bridge 140 can also be automatically and quickly moved to the left or right of the base 180 by rotating the left-right movement trapezoidal screw 192 with a left-right movement motor.

[0062] Furthermore, the tip safety fence 146a of the boarding bridge 140 is temporarily removed, turned over, and then reattached to the tip of the boarding bridge 140 so that it can accommodate the left boarding / alighting opening 110b (see FIG. 8(b)). Furthermore, the opening closing safety fence 146b is removed and attached so as to block the boarding / alighting opening 141a (see FIG. 8(b)). In this way, simply by switching the tip safety fence 146a and the opening closing safety fence 146b of the boarding bridge 140, the opening of the boarding bridge 140 can accommodate the right boarding / alighting opening 110a and the left boarding / alighting opening 110b of the cockpit 110, respectively.

[0063] Figure 8(a) is a schematic plan view showing the boarding bridge 140 at the left boarding / alighting entrance 110b of the cockpit 110 according to an embodiment of the present invention, i.e., at a position corresponding to the left handle, Figure 8(b) is an enlarged oblique view showing the tip of the boarding bridge 140 shown in Figure 8(a), and Figure 8(c) is an enlarged oblique view showing the left-right movement mechanism 190 for moving the boarding bridge 140, which is located on the left side of the base 180, to the right.

[0064] 8(a), when the cockpit 110 has a left-hand drive, the boarding opening 141b of the boarding bridge 140 opens to the right of the third bridge 143c, opposite to the boarding opening 141a described above. This allows the driver to get in and out of the cockpit 110 using the boarding opening 141b and the left boarding / alighting door 110b that opens on the left side of the cockpit 110.

[0065] 8(b), when the cockpit 110 is a left-hand drive type, the left side of the tip safety fence 146a is lower than the right side when viewed from the front in order to avoid the side mirror on the left side of the cockpit 110. In addition, the opening closing safety fence 146b is fitted to the left side of the third bridge 143c, and the boarding / alighting opening 141b is open on the right side of the third bridge 143c.

[0066] As shown in FIG. 8(c), the boarding bridge 140 is provided with a boarding bridge left-right movement mechanism 190 on the entrance door 142 side, as described above.

[0067] When the boarding bridge 140 is handed over to the left-hand cockpit 110, as described above, the boarding bridge 140 is moved to the left side on the base 180.

[0068] Here, when the cockpit 110 is converted to a right-hand drive and passengers board or disembark from the cockpit 110 through the right boarding / alighting door 110a that opens on the right side of the cockpit 110, the boarding bridge 140 is moved to the right side of the base 180 using the left / right movement mechanism 190, in the opposite manner to that described above.

[0069] Movement of the boarding bridge 140 to the right is achieved by rotating the left-right movement handle 191 clockwise, in the opposite direction to the above, so that the left-right movement trapezoidal screw 192 sends the boarding bridge 140 to the right of the base 180. At this time, the boarding bridge 140 moves to the right of the base 180 along the left-right movement linear guide 193.

[0070] Also, the tip safety fence 146a of the boarding bridge 140 is temporarily removed, turned over, and then reattached to the boarding bridge 140 so that it can accommodate the right boarding / alighting opening 110a (see FIG. 5(b)). Also, the opening closing safety fence 146b near the tip of the boarding bridge 140 is removed and attached so as to close the boarding / alighting opening 141b (see FIG. 5(b)).

[0071] In this way, the left-right movement mechanism 190 can move one boarding bridge 140 to be positioned on the right or left side of the base 180. This allows it to accommodate different right boarding / alighting entrances 110a and left boarding / alighting entrances 110b depending on whether the cockpit 110 has a right-hand drive or a left-hand drive, and one boarding bridge 140 can be used for boarding and alighting from the different right boarding / alighting entrances 110a and left boarding / alighting entrances 110b.

[0072] <Other embodiments> 9(a) and 9(b) are schematic plan views of a boarding bridge 240 according to another embodiment of the present invention, as viewed from above. In this embodiment, the cockpit 110 stops so that its center is on an extension of the center line L2 of the base 280 in a plan view, and the stopping position is the same whether the cockpit 110 corresponds to a right-hand drive or a left-hand drive vehicle.

[0073] FIG. 9( a ) shows a boarding bridge 240 of another embodiment of the present invention located on the right side of the cockpit 110 , corresponding to a right-hand drive cockpit 110 .

[0074] FIG. 9(b) shows another embodiment of the invention in which a boarding bridge 240 is located on the left side of the cockpit 110, corresponding to a left-hand drive cockpit 110.

[0075] The components having names corresponding to those of the boarding bridge 140 described above have the same functions, and therefore detailed explanations thereof will be omitted.

[0076] As shown in Figures 9(a) and 9(b), the base 280 to which the boarding bridge 240 is fixed has a wider left-right width in a plan view than the base 180 described above. As a result, the boarding bridge 240 located on the right side of the cockpit 110, corresponding to the right-hand drive cockpit 110 shown in Figure 9(a), can be moved to the left across the entire width of the base 280 using the left-right movement mechanism 290 as described above. Note that "left" and "right" here refer to the left and right sides, respectively, of the center line L2 of the base 280 in Figures 9(a) and 9(b).

[0077] In addition, corresponding to the left-hand drive cockpit 110 shown in Figure 9(b), the boarding bridge 240 located on the left side of the cockpit 110 can be similarly moved to the right across the full width of the base 280 using the left-right movement mechanism 290.

[0078] In this case, for a cockpit 110 that has the same stopping position when it is compatible with right-hand and left-hand steering wheels, a single boarding bridge 240 can be used for both the right boarding / alighting entrance 110a and the left boarding / alighting entrance 110b.

[0079] In the above description, the cockpit 110 has access doors on both the left and right sides, and the cockpit 110 is interchangeable to accommodate right-hand and left-hand drive vehicles, but this is not limiting. For example, the cockpit may have access doors on only one side, either the right or left (in which case they are interchangeable), or a single cockpit may have handles on both the left and right sides and access doors on the corresponding left and right sides.

[0080] With the above configuration, it is possible to provide a boarding / exiting device that can use a single boarding bridge to accommodate the different boarding / exiting entrances on the left and right sides of the cockpit of the driving simulator, allowing passengers to board and exit from either entrance.
