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] Conventionally, as an example of a simulator, for example, a driving simulator described in Patent Document 1 changes the attitude of a simulated vehicle body relative to a floor surface by a servo cylinder. By combining this change in the attitude of the simulated vehicle body (cockpit) relative to the floor surface with an image projected by a projector on a screen, it is possible to simulate the situation in which a driver inside the simulated vehicle body is driving an automobile.

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

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

[0005] Incidentally, it is preferable that a driving simulator can be used with both right-hand drive and left-hand drive cockpits. In this case, if the entrance of the boarding / alighting device is set to correspond to the cockpit of the right-hand drive, it will be difficult for a driver to get in and out of the cockpit of the left-hand drive. For example, the driver needs to move through the relatively narrow cockpit to get to the seat of the left-hand drive. To solve this problem, it is possible to use two boarding / alighting devices, but this will lead to problems such as increased costs.

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

[0007] In order to solve the above problems, 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 moving mechanism for moving the bridge relative to the platform and positioning the bridge in correspondence with one or the other boarding and alighting doors of the cockpit.

[0008] In addition, in the boarding / alighting device, the bridge may further include an extension mechanism.

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

[0010] In addition, in the above-mentioned boarding and disembarking device, the movement mechanism may include a trapezoidal screw for left and right movement.

[0011] In addition, in the 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 either the left or 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 and disembarking 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 and extend and deploy relative to each other when in use.

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

[0015] In addition, the boarding / alighting device may be configured so that the extension mechanism is a lift-up bridge.

[0016] In addition, the boarding / alighting device may be configured so that the telescopic mechanism is a rotating bridge.

[0017] In addition, the boarding / alighting device may be configured so that the bridge has a truss structure. Effect of the Invention

[0018] According to the present invention, a single boarding and alighting device can be used to accommodate the different boarding and alighting entrances on the left and right sides of the simulator cockpit, making it possible for passengers to board and alight from either entrance.

[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 an embodiment of the present invention.

[0022] As shown in FIG. 1, the driving simulator 100 includes a cockpit 110, an actuator system 120 for operating the cockpit, a screen 130 for displaying the view seen from the cockpit in response to the operation of the cockpit, a boarding bridge 140 as an access device for the cockpit 110, a platform 150 on which the access device is provided and on which the driver gets on and off, and a concave pit 160 (see FIG. 3(b)) on which the actuator system 120 is arranged and which has a bottom surface (floor surface) 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, which is a movement mechanism for moving the boarding bridge 140 to the left and right of the base 180. That is, in this embodiment, the cockpit 110 is used as two types, one for a right-hand drive vehicle and one for a left-hand drive vehicle, which are interchangeable as necessary (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 is for a right-hand drive or a left-hand drive, to correspond to the entrance and exit of the cockpit 110. Note that, although the present embodiment relates to a simulator of an automobile as the driving simulator 100, it is not limited thereto. For example, it is clear from the following description that the driving simulator 100 may be a simulator of a moving body such as a railroad car or an aircraft. Also, in the present embodiment, the case where the driving simulator 100 has the pit 160 is described, but it is not limited thereto. For example, the pit 160 may not be provided, and only the platform may be raised to a high position from the floor surface in accordance with the position of the cockpit.

[0023] The cockpit 110 (FIG. 1 shows a right-hand drive version) is a boarding section where a driver boards and simulates driving, and is provided with a configuration for driving that imitates 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 a plurality of boarding / alighting doors, and in this embodiment, a right boarding / alighting door 110a and a left boarding / alighting door 110b corresponding to the right door 115 and the left door 116, respectively. A boarding bridge (boarding / alighting device) 140 for the driver to board and alight from the cockpit 110 is provided on a platform 150, and as will be described in detail later, when the driver boards and alights, the boarding bridge 140 extends as a whole, and its tip portion is in a position corresponding to the right boarding / alighting door 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 extends into a pit 160 in which the actuator system 120 is provided, and touches the floor surface 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 performed, the boarding bridge 140 is contracted as a whole with the support legs 172 contracted, and is positioned on the platform 150 (see FIG. 4A(a)). That is, when using the driving simulator 100, first, the boarding bridge 140 is extended so that its tip corresponds to a 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, travels along the safety fence 146 to the boarding / alighting opening 141a, and gets on the cockpit 110 through this opening. After using the driving simulator 100, the driver moves from the cockpit 110 to the boarding bridge 140 through the boarding and disembarking opening 141a at the tip of the boarding bridge 140, in the reverse order to the above, and moves to the platform 150 through the entrance door 142 on the platform 150 side of the boarding bridge 140. After that, the boarding bridge 140 is contracted and stored.

[0024] 2(a) and 2(b) are schematic plan views showing 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. The cockpit stopping positions are positions where the driver gets on and off during the simulation.

[0025] 2(a), when the cockpit 110 is a right-hand drive aircraft, the cockpit 110 stops at a stopping position 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 in a left-hand drive aircraft.

[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, and the tip of the boarding bridge 140 reaches a position adjacent to the cockpit 110. At this time, the boarding bridge 140 extends to the cockpit 110 stopped at a predetermined stop position, but does not contact 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, thereby ensuring a boarding and disembarking path for the driver from the boarding bridge 140 to the cockpit 110. In addition, since the boarding bridge 140 does not contact the cockpit 110, the weight of the boarding bridge 140 and the impact when it is extended or contracted are not applied to the cockpit 110, and there is no effect on the cockpit 110 and the actuator system 120 described later. In addition, in the case of a boarding bridge 140 that is compatible with a left-hand steering wheel, the left door 116 of the cockpit 110 opens toward the boarding and disembarking 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 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, the boarding bridge 140 of this embodiment can be used to easily install and remove the boarding bridge 140 relative to the cockpit 110. In addition, 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 can obtain a high sense of immersion.

[0031] 1 and 3(b), the actuator system 120 includes three actuators 121a, 121b, and 121c that are arranged at three positions along the circumferential direction at equal intervals so as to surround the periphery of the cockpit 110. These three actuators can be partially contracted in their respective axial directions, and are connected to a swing base 111 fixed to a cockpit support provided on the bottom side of the cockpit 110 via a hexapod 124. The hexapod 124 is fixed to a base plate 126. As a result, the actuator system 120 can drive the actuators 121a, 121b, and 121c by a driving source such as hydraulic pressure, and can move the cockpit 110 in two axial directions, X and Y. The hexapod 124 can also move the cockpit 110 with six degrees of freedom in 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 so as to surround 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 from the floor of the pit in order to avoid the drive sources and hydraulic pipes of actuators 121a, 121b, and 121c installed on the floor of pit 160.

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

[0034] Here, drive mechanisms for the three actuators 121a, 121b, 121c, the hexapod 124, etc. 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 above-mentioned drive mechanisms are provided in a pit that is a recessed portion relative to the platform 150. In addition, since a pit is provided, boarding and disembarking to and from the cockpit 110 is performed 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 in which the driving simulator 100 is installed and to board onto the upper part of the boarding bridge 140. The platform 150 is made of, for example, concrete and has a horizontal floor surface on the upper part. The platform 150 also has the above-mentioned pit 160 in the center.

[0036] The boarding bridge 140 is attached and fixed to the platform 150 via a base 180. The base 180 is fixed by being embedded into the platform 150 when laying the concrete that constitutes the platform 150. The base 180 is also supported on the floor surface 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 or left-hand drive, as will be described in detail later.

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

[0039] FIG. 4A(a) is a perspective view showing a stored state of the boarding bridge 140 corresponding to the right boarding / alighting door 110a according to an embodiment of the present invention. In this embodiment, the boarding bridge 140 includes a bridge 143 having a structure in which rectangular frames that also serve as a safety fence 146 are connected. The bridge 143 includes a plurality of bridges, and is composed of a first bridge 143a that is a fixed part to the platform 150, a second bridge 143b that is an intermediate part, and a third bridge 143c that is a tip part. The bridge includes an extension 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 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 that is a fixed base for fixing 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 and contracted to be stored together on the base 180 by the telescopic mechanism. The bridge 143 may be, for example, a truss structure. If the bridge 143 has a truss structure, the rigidity of the bridge 143 can be sufficiently ensured during telescopic expansion and contraction and after the extended deployment, and the telescopic expansion of the bridge 143 and the telescopic expansion of the support legs 172 described later are not hindered. In this embodiment, the bridge 143 is composed of three bridges, which are multiple bridges, but is not limited to this, and may be composed of, for example, two bridges, four bridges, or five or more bridges.

[0040] FIG. 4A(b) is a perspective view showing a state in the middle of deployment during use of the boarding bridge 140 corresponding to the right boarding / alighting door 110a according to the embodiment of the present invention. From the above-mentioned stored state, the third bridge 143c is extended and deployed toward the cockpit 110 relative to the first bridge 143a along the first linear guide 148c for extension and extension, by rotating the first ball screw 148b for extension and extension, which is a telescopic mechanism, using the first motor 148a for extension and extension, which is a drive device for driving the telescopic mechanism. At the same time, the second motor 149a for extension and extension is used to rotate the second ball screw 149b for extension and extension, which is a telescopic mechanism, by which the second bridge 143b is extended and deployed toward the cockpit 110 relative to the first bridge 143a along the second linear guide 149c for extension and extension. In this way, since the telescopic mechanism is configured by a ball screw, the telescopic mechanism can increase the speed of extension and extension compared to the case of using other screws. As described 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 toward the cockpit 110, preventing collision with the cockpit 110, the screen 130, and other peripheral equipment. Because of this nested structure, the number of parts is smaller and the system is simpler than when the bridge is of the bellows type or pantograph type, and furthermore, the installation of a safety fence is easier.

[0041] 4B(c) is a perspective view showing the state where the boarding bridge 140 corresponding to the right boarding / alighting door 110a in the embodiment of the present invention is fully deployed when in use. 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 described below, in order to support the tip of the boarding bridge 140, the support legs 172 extend from the storage section 171 of the tension jack 170 toward the floor surface inside the pit 160.

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

[0043] In this embodiment, the boarding bridges 140 are stored in a nested structure, but are not limited to this. 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 to a position above the platform 150 and becomes stationary. Alternatively, instead of being lifted up, a rotating bridge may be used in which the tip of the bridge rotates toward the platform 150 so as to draw an arcuate trajectory in a plan view and becomes stationary. Alternatively, a bridge having an integral structure may move directly to the vicinity of the cockpit 110 and 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 the tip. This allows the boarding bridge 140 to extend to the cockpit 110 without being hindered by the actuators 121a, 121b, 121c and hydraulic pipes that crawl on the floor surface 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 surface on which the driving simulator is installed.

[0045] Furthermore, as described above, if the boarding bridge is stored by a flip-up or rotating system, it is not necessary to make the bridge part of the boarding bridge into 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 an 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 of the boarding bridge 140, is stored in the storage section 171. As described above, the support leg 172 maintains a state in which it is stored in the storage section 171 until the boarding bridge 140 is fully deployed. The support leg 172 has a leg portion 172a made of 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 support leg 172 can be kept stationary relative to the storage section 171 due to the frictional force between the leg portion 172a and the storage section 171 and the frictional force between the gear of the jack motor 173 and the drive shaft 174. 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 a state in which the support leg 172 extends and reaches the floor surface in 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 the driving force is transmitted through the gear, the drive shaft 174, and the leg 172a. As a result, the support leg 172, which is a ball screw, extends from the storage section 171 to the floor surface in the pit. The support leg 172 has a foot 172b, and when the foot 172b touches the floor surface in the pit, the jack motor 173 stops rotating. The support leg 172 remains stationary relative to the storage section 171 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. 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, and the boarding bridge 140 does not bend or twist, allowing the driver to safely approach the cockpit 110 using the boarding bridge 140 and to safely board. 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 expand and contract. 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 having the support legs 172 which are ball screws is used, but the support legs are not limited to this. For example, a trapezoidal screw or a worm gear 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 the 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 moves to the left. Note that here, "left" and "right" refer to the left and right sides, respectively, of the center line L1 of the base 180 in Figs. 2(a) and (b).

[0051] 6(a), when the cockpit 110 is a right-hand drive vehicle, 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 on and off the cockpit 110 using the boarding opening 141a and the right boarding / alighting door 110a that opens to 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 to 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 type, 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. Also, the opening closing safety fence 146b is fitted to the right side of the third bridge 143c, and the getting on and off opening 141a is open on the left side of the third bridge 143c.

[0054] As shown in Fig. 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 described in the following section with reference to Figs. 7(a) and (b).

[0055] When the boarding bridge 140 is delivered to the cockpit 110 for a right-hand drive aircraft, the boarding bridge 140 is located 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 and disembark from the cockpit 110 through the left boarding / alighting door 110b opened 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 a detailed configuration of the left-right movement mechanism 190 according to the embodiment of the present invention, and shows a 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, which is tightened after the bridge is moved to fix rotating shaft 195, rotating shaft 195 which transmits the rotation of left / right movement handle 191 to miter gear 196 at the bottom, and miter gear 196 which 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 the trapezoidal screw 192 for left-right movement by abutting a nut 198 of the trapezoidal screw 192 for left-right movement 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-mentioned 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, counterclockwise by hand, which rotates the rotation shaft 195, and the miter gear 196 converts the rotation into a right-angle rotation, which rotates the left-right movement trapezoidal screw 192, and the boarding bridge 140 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 stops, the manual clamp 194 is tightened to fix the rotation shaft 195. This makes it possible to prevent the boarding bridge 140 from moving left and right.

[0061] Since the boarding bridge 140 can be moved to the left of the base 180 by manually rotating the left-right movement handle 191, the left-right movement of the platform 150 can be realized with a simple configuration. In addition, since a trapezoidal screw is used, costs can be reduced compared to when a ball screw is used. Furthermore, since the frictional force is low and the feed pitch is small compared to when a triangular screw is used, the left-right movement handle 191 can be turned manually with a small force. However, the rotation of the left-right movement handle 191 is not limited to manual operation, and the boarding bridge 140 can 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] Also, the tip safety fence 146a of the boarding bridge 140 is once 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)). Also, the opening closing safety fence 146b is removed and then 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 respectively accommodate the right boarding / alighting opening 110a and the left boarding / alighting opening 110b of the cockpit 110.

[0063] Figure 8(a) is a schematic plan view showing the left boarding / alighting entrance 110b of the cockpit 110 according to an embodiment of the present invention, i.e., the boarding bridge 140 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 is 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 on and off the cockpit 110 using the boarding opening 141b and the left boarding / alighting door 110b opened 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 left side mirror of the cockpit 110. Also, the opening closing safety fence 146b is fitted to the left side of the third bridge 143c, and the boarding and alighting opening 141b is opened on the right side of the third bridge 143c.

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

[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 and disembark from the cockpit 110 through the right boarding and alighting door 110a opened 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 manner to the above, so that the left / right movement trapezoidal screw 192 sends the boarding bridge 140 to the right side of the base 180. At this time, the boarding bridge 140 moves to the right side 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 once removed so as to be compatible with the right boarding / alighting opening 110a, and then reattached to the boarding bridge 140 after being turned over (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 located on the right or left side of the base 180. This allows the cockpit 110 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. 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 steering wheel or a left-hand steering wheel.

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

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

[0075] Components having names corresponding to those of the boarding bridge 140 described above have the same functions, so detailed explanations will be omitted.

[0076] As shown in Fig. 9(a) and Fig. 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 above-mentioned base 180. Then, the boarding bridge 240 located on the right side of the cockpit 110 corresponding to the right-hand cockpit 110 shown in Fig. 9(a) can be moved to the left side to the full width of the base 280 by using the left-right movement mechanism 290 as described above. Note that here, "left" and "right" refer to the left and right sides, respectively, of the center line L2 of the base 280 in Fig. 9(a) and (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 similarly be moved to the right across the full width of the base 280 using the left-right movement mechanism 290.

[0078] In this way, 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 the right boarding / alighting entrance 110a and the left boarding / alighting entrance 110b.

[0079] In the above description, the cockpit 110 has entrances on both the left and right sides, and the cockpit 110 is interchangeable to accommodate right-hand and left-hand drive steering wheels, but this is not limited to this. For example, the cockpit may have entrances 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 entrances on the corresponding left and right sides.

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