As shown in FIG. 6, the skydiving simulator 500 of Patent Document 1 is provided with an annular wind tunnel 510 that has a substantially square ring shape in a cross-sectional view.
The annular wind tunnel 510 includes a first vertical wind tunnel 512 extending in the vertical direction, a pair of second vertical wind tunnels 513 and 513 disposed in parallel to the first vertical wind tunnel 512, and the first vertical wind tunnel 512 and the second vertical wind tunnel 512. The vertical wind tunnels 513 and 513 are respectively composed of a first horizontal wind tunnel 514 connected at the upper part thereof and a second horizontal wind tunnel 515 connected at the lower part thereof.

  Blowers 520 and 520 for sending the air AR toward the second vertical wind tunnels 513 and 513 are arranged in the upper first horizontal wind tunnel 514 in the annular wind tunnel 510. In the annular wind tunnel 510, a circulation path 511 through which air sent from the blowers 520 and 520 flows is formed.

  A floating space 516 in which the player M floats is provided in the middle of the first vertical wind tunnel 512 in the longitudinal direction. In the floating space 516, the air AR sent from the blowers 520 and 520 moves from the lower side (floor surface 516a side) to the upper side (ceiling 516b side). The person M is suspended.

In this type of skydiving simulator 500, an opening 516c through which the player M enters and leaves the floating space 516 is opened through the first vertical wind tunnel 512 in the thickness direction.
Therefore, the flow of the air AR moving from the floor surface 516a side to the ceiling 516b side in the floating space 516 is affected by the opening 516c. As a result, the player feels that the player who is floating in the floating space 516 feels the air flow. There was a sense of discomfort.

  Therefore, it is required not to give an uncomfortable feeling to a player who is playing with a skydiving simulator.

Of the edges surrounding the opening in the vertical wind tunnel, the downstream edge along the circumferential direction of the vertical wind tunnel on the downstream side in the air flow direction in the floating space is the downstream edge of the vertical wind tunnel. It is curved in such a direction that the opening diameter between the upstream side edge portion becomes narrower toward the front end side, and the front end portion of the downstream side edge portion is positioned outside the vertical wind tunnel. .

According to the present invention, of the air that moves in the floating space from below to above, a part of the air that passes through the upstream edge of the opening is caused by delamination that occurs at the upstream edge. The turbulent flow generated at the upstream edge moves toward the downstream edge.
The downstream edge of the opening is curved in such a direction that the opening diameter between the upstream edge and the downstream edge becomes narrower toward the distal end of the downstream edge, and the distal edge of the downstream edge When the part is positioned outside the vertical wind tunnel, most of the turbulent flow generated at the upstream edge can be moved along the curved part of the downstream edge and guided to the downstream side of the floating space. .
Thereby, since the diffusion of the turbulent flow generated at the upstream edge portion into the floating space can be suitably prevented, it is possible to reduce the uncomfortable feeling of the player who is playing with the skydiving simulator.

It is a figure explaining the frame member surrounding the circumference of the opening concerning an embodiment. It is a schematic sectional drawing explaining the skydiving simulator of a prior art example.

Hereinafter, the skydiving simulator 1 according to the embodiment will be described.
FIG. 1 is a schematic cross-sectional view illustrating the configuration of the skydiving simulator 1.

  As shown in FIG. 1, in the skydiving simulator 1, a first vertical wind tunnel 12 extending linearly in the vertical direction, and a pair of second vertical wind tunnels 13 a and 13 b provided in parallel to the first vertical wind tunnel 12, Are provided, and a first horizontal wind tunnel 14a connecting the first vertical wind tunnel 12 and the second vertical wind tunnels 13a, 13b at the top and a second horizontal wind tunnel 14b connecting the bottoms together. Is provided.

  In the skydiving simulator 1, an annular wind tunnel 10 having a substantially quadrangular ring shape is formed by a first vertical wind tunnel 12, second vertical wind tunnels 13a and 13b, a first horizontal wind tunnel 14a, and a second horizontal wind tunnel 14b. Is formed. The annular wind tunnel 10 is formed with a circulation path 11 through which air AR described later flows.

  A floating space 20 in which the player M floats is provided at an intermediate position in the longitudinal direction (vertical direction) of the first vertical wind tunnel 12.

  The floating space 20 is a space surrounded by a cylindrical peripheral wall 21, and a mesh member (safety net) is stretched over the floor surface 201 below the floating space 20.

The floating space 20 is provided so as to extend linearly up to the upper side of the first vertical wind tunnel 12, and a diameter-enlarged portion 203 whose channel cross section expands upward is formed in the upper portion 202 of the floating space 20. Has been.
Therefore, the air AR moving upward in the floating space 20 is designed to have a lower wind speed when passing through the enlarged diameter portion 203. The radial cross-sectional area of the enlarged diameter portion 203 in the vicinity of the advancing direction changing members 44 and 45 described later is such that the player AR floating in the floating space 20 does not collide with the advancing direction changing members 44 and 45. It is set to a size that can reduce the wind speed.

The second vertical wind tunnels 13a and 13b are respectively provided in parallel to the first vertical wind tunnel 12, and the second vertical wind tunnels 13a and 13b are provided at the same distance across the first vertical wind tunnel 12. It has been.
In the middle of the longitudinal direction of the second vertical wind tunnels 13a, 13b, blowers 30a, 30b for sending out the air AR direct the respective discharge ports 31a, 31b to the lower portions of the second vertical wind tunnels 13a, 13b. It is provided in the state.
The blowers 30a and 30b use axial fans in which the suction ports 32a and 32b and the discharge ports 31a and 31b are provided on the same central axis.

  With the above configuration, the air AR sent from the blowers 30 a and 30 b moves along the circulation path 11 formed in the annular wind tunnel 10 and is sent to the floating space 20 provided in the first vertical wind tunnel 12.

Here, the length in which the air AR flows from the blower 30a to the floating space 20 in the circulation path 11 and the length in which the air AR flows from the blower 30b to the floating space 20 are set to be equal.
Therefore, the air volume difference between the air AR sent from the blower 30a and the air AR sent from the blower 30b (the enlarged diameter portion 48 provided in the first vertical wind tunnel 12 to be described later) does not increase. The turbulent flow generated in the part is suppressed.

[Direction changing member]
As shown in FIG. 1, the annular wind tunnel 10 is provided with a plurality of traveling direction changing members 40 to 47 for smoothly changing the moving direction of the air AR along the circulation path 11.

The traveling direction changing members 41 and 43 are provided at the connecting portion between the lower part of the second vertical wind tunnels 13a and 13b and the second horizontal wind tunnel 14b, and the traveling direction changing members 46 and 47 are the second horizontal wind tunnels. 14 b and a lower portion of the first vertical wind tunnel 12 are provided.
Further, the traveling direction changing members 40, 42 are provided at the connection portion between the upper portions of the second vertical wind tunnels 13a, 13b and the first horizontal wind tunnel 14a. It is provided at a connection portion between the horizontal wind tunnel 14 a and the upper portion of the first vertical wind tunnel 12.

The traveling direction changing members 40 and 41 described above are arranged so as to cross the flow path cross section of the air AR of the second vertical wind tunnel 13a, and the traveling direction changing members 42 and 43 are formed of the air AR of the second vertical wind tunnel 13b. It arrange | positions so that a flow-path cross section may be crossed.
The traveling direction changing members 44 and 45 are arranged so as to cross the flow path cross section of the air AR of the first horizontal wind tunnel 14a, and the traveling direction changing members 46 and 47 are disposed of the air AR of the second horizontal wind tunnel 14b. It arrange | positions so that a flow-path cross section may be crossed.

  Here, since the basic shapes and configurations of the traveling direction changing members 40 to 47 are substantially the same, in the following description, the connection between the lower portion of the second vertical wind tunnel 13a and the second horizontal wind tunnel 14b. The advancing direction changing member 41 provided in the portion will be described, and the other advancing direction changing members 40 and 42 to 47 will be appropriately described as necessary.

2A and 2B are diagrams for explaining the traveling direction changing member 41, wherein FIG. 2A is a schematic perspective view of the traveling direction changing member 41, and FIG. 2B is an enlarged sectional view of the region A in FIG. is there.
As shown to (a) of FIG. 2, in the advancing direction change member 41, the several blade member 41a is arrange | positioned at equal intervals in the thickness direction in the position where it is mutually parallel.

  As shown in FIG. 2B, each of the blade members 41a has a curved shape in which the center portion 41a3 in the width direction of the base portion 41a1 of the blade member 41a is offset from the line segment connecting both sides in the width direction. Yes.

  Thereby, the air AR that is sent from the blower 30a and moves downward in the second vertical wind tunnel 13a has a plurality of blade members 41a arranged so as to cross the flow path cross section of the second vertical wind tunnel 13a. The traveling direction is changed along the curved shape of the base portion 41a1, and the inside of the second horizontal wind tunnel 14b moves toward the first vertical wind tunnel 12 (see the flow path A1 in FIG. 1 and the arrow in FIG. 2B). .

The central part 41a3 of the base part 41a1 of the blade member 41a is a thick part formed thicker than both sides 41a4 and 41a4 in the width direction of the blade member 41a, and the thick part is in the longitudinal direction of the blade member 41a. A hole 41a2 is formed.
The hole 41a2 is a flow path through which the cooling fluid flows. The cooling fluid is passed through the flow path to cool the entire blade member 41a.

In the embodiment, the air AR sent from the blowers 30 a and 30 b circulates in the annular wind tunnel 10 along the circulation path 11, and between the circulating air AR and the inner wall surface of the annular wind tunnel 10. Friction occurs.
Therefore, the air AR is gradually warmed by frictional heat with the inner wall surface of the annular wind tunnel 10 while circulating in the annular wind tunnel 10. And if the temperature of the air in the annular wind tunnel 10 becomes too high, the game of the player M in the floating space 20 becomes difficult.

If comprised as mentioned above, while the air AR changes the advancing direction along the base 41a1 of curved shape, heat exchange is performed between the air AR and the cooled base 41a1, and the temperature of the air AR becomes idle. The temperature can be lowered to a suitable temperature.
Note that a coolant such as Freon gas or LLC (Long Life Coolant) is used as the coolant.

[rectifier]
Next, the rectifier 481 disposed in the enlarged diameter portion 48 in the first vertical wind tunnel 12 will be described.
3A and 3B are diagrams for explaining the rectifier 481. FIG. 3A is a schematic perspective view showing a part of the rectifier 481, and FIG. 3B is a schematic view of the cylindrical member 482 constituting the rectifier 481. It is a schematic perspective view.

  As shown in FIGS. 3A and 3B, in the rectifier 481, a plurality of cylindrical members 482 having substantially hexagonal openings in a cross-sectional view are arranged with the side surfaces 482b in close contact with each other without gaps. Has been. Since the rectifier 481 has a so-called honeycomb structure, it has a very strong structure against compressive stress in the longitudinal direction (axial direction).

The rectifier 481 is disposed across the flow path cross section of the first vertical wind tunnel 12 in a direction in which the openings 482a of the plurality of cylindrical members 482 are aligned with the flow direction of the air AR (see FIG. 1).
Among the air AR that moves from the lower side to the upper side of the first vertical wind tunnel 12, the turbulent air is adjusted in the moving direction while passing through the cylindrical member 482 of the rectifier 481.

  Here, a player who is playing with this type of skydiving simulator may feel a sense (discomfort or discomfort) different from that of skydiving performed by descending from an aircraft. The inventor of the present application has examined the cause and found that the player feels uncomfortable and uncomfortable when the air flow received by the player includes turbulent flow.

  As described above, in the embodiment, the rectifier 481 is provided below the floating space 20, and the turbulent air AR is rectified by the rectifier 481 and then sent to the floating space 20. If it does in this way, the air AR without the turbulent flow which rectified will hit the player M, and the discomfort and discomfort of the player M in the floating space 20 can be reduced.

[Reduced diameter section]
As shown in FIG. 1, between the floating space 20 and the rectifier 481 in the first vertical wind tunnel 12, the rectifier 481 side is directed to the floating space 20 side (from the downstream side to the upstream side in the air flow direction). Accordingly, a reduced diameter portion 49 (confuser) is provided in which the flow path cross section of the first vertical wind tunnel 12 becomes narrower. Therefore, the reduced diameter portion 49 is provided above the rectifier 481 described above.

  In the embodiment, the floating space 20 is provided immediately after the reduced diameter portion 49 in the direction in which the air AR is sent out (the direction of the arrow in FIG. 1). When the air AR passes through the reduced diameter portion 49, the wind speed is increased. Then, the air AR with the increased wind speed is sent to the floating space 20 provided immediately after the reduced diameter portion 49, whereby the wind speed of the air AR that lifts the player M upward in the floating space 20 increases. .

  In the floating space 20, the player M is stably floated by balancing the force that lifts the player M upward due to the flow of the air AR (wind speed) and the force that causes the player M to drop due to the weight of the player M. It is like that.

[Standby space]
Next, the standby space 50 provided adjacent to the outside of the floating space 20 will be described.
4A and 4B are diagrams illustrating the standby space 50 and the decompression space 57. FIG. 4A is a schematic perspective view of the periphery of the standby space 50, the decompression space 57, and the floating space 20, and FIG. It is a schematic plan view of the periphery of the standby space 50, the decompression space 57, and the floating space 20 seen, and (c) is a cross-sectional view of the peripheral wall 21 around the LED device 211 taken along the plane A in (a).
5A and 5B are diagrams illustrating the frame portion 23 surrounding the periphery of the opening 22, and FIG. 5A is a front view around the opening 22 viewed from the floating space 20 side, and FIG. ) Is a cross-sectional view taken along the line AA in FIG. 5C, and FIG.

  As shown in FIGS. 4A and 4B, a standby space 50 surrounding a part of the floating space 20 is provided outside the floating space 20.

  The standby space 50 is a space partitioned by a peripheral wall 21 that surrounds the floating space 20 when viewed from above the first vertical wind tunnel 12 and an outer wall 52 that is provided at a position away from the peripheral wall 21 by a predetermined distance. is there.

  The peripheral wall 21 surrounding the floating space 20 is provided with an opening 22 that penetrates the peripheral wall 21 in the thickness direction. The standby space 50 and the floating space 20 communicate with each other through the opening 22 so that the player M can enter and leave the floating space 20 through the opening 22.

  In the front view as viewed from the floating space 20 side, the opening 22 has a rectangular shape with the vertical direction as the longitudinal direction, and is open equally to the left and right with respect to the diameter line X of the cylindrical peripheral wall 21. (See (b) of FIG. 4 and (a) of FIG. 5).

Here, the applicant of the present application, when the opening 22 opening in the floating space 20 is formed, the flow passage cross-sectional area of the air flowing through the floating space 20 changes in the opening 22 portion. It has been found that air turbulence occurs due to air separation at the edge of 22.
Therefore, in the embodiment, the shape of the frame portion 23 surrounding the opening 22 is devised in order to reduce the influence of turbulent flow generated in the opening 22.

  Specifically, the upper frame portion 231 along the upper edge of the opening portion 22 and the side frame portions 233 and 233 that extend downward from both sides in the width direction of the upper frame portion 231 on the lower frame portion 232 side, respectively. The frame portion 23 is formed by being curved toward the outside of the floating space 20 (the waiting space 50 side).

Here, the turbulent flow generated in the lower frame portion 232 will be described.
As shown in FIG. 5B, a part of the air AR that crosses the lower frame portion 232 of the opening 22 out of the air AR that moves in the floating space 20 from the lower side to the upper side is the lower frame portion 232. Is diffused toward the outside of the opening 22 (the side of the standby space 50) when passing through, the turbulent flow due to air separation occurs at the tip 232a of the lower frame portion 232.
Then, the generated turbulent flow moves toward the upper frame portion 231 along the air moving direction.
Here, when the upper frame portion 231 is not curved and formed as shown in FIG. 5C, the turbulent flow that has collided with the tip 231A of the upper frame portion 231 is separated from the floating space 20 side. Each diffuses to the space 50 side. And the turbulent flow diffused to the floating space 20 side affects the floating feeling of the player who is floating in the floating space 20 and brings a sense of incongruity to the player. In addition, the turbulent flow diffused toward the standby space 50 gives minute vibrations to the air in the standby space 50, thereby bringing a sense of incongruity to the player who is waiting in the standby space 50.

  Here, in the embodiment, as shown in FIG. 5B, the opening diameter D1 between the upper frame portion 231 and the lower frame portion 232 becomes narrower toward the tip 231a side of the upper frame portion 231. The tip 231a is positioned in the standby space 50 outside the peripheral wall 21, and a portion facing the lower frame portion 232 is a curved surface 231b.

Therefore, when the turbulent flow generated in the lower frame portion 232 and moved toward the upper frame portion 231 reaches the curved surface 231b, the curved surface 231b is curved toward the floating space 20, and therefore the lower frame portion 232 is bent. Therefore, it moves to the floating space 20 side instead of the tip 231a side parallel to the surface.
As a result, almost all of the turbulent flow that has reached the upper frame portion 231 moves upward in the floating space 20 along the curved surface 231b.
Therefore, the turbulent flow that has reached the upper frame portion 231 moves upward along the peripheral wall 21 in the floating space 20 without diffusing into the floating space 20 or the standby space 50.

In the embodiment, the radius of curvature R of the curved surface 231b is set to a radius of curvature that prevents the turbulent flow that moves along the curved surface 231b from separating from the curved surface 231b.
In addition, the air that collides with the lower frame portion 232 and becomes turbulent flow moves toward the standby space 50 toward the upper frame portion 231, so that the turbulent flow in the radial direction until the upper frame portion 231 is reached. The width H1 from the inner wall surface 21a of the peripheral wall 21 of the curved surface 231b to the tip 231a is set so as to be larger than the movement amount H2.

Therefore, most of the air that collides with the lower frame portion 232 and becomes turbulent flows reaches the curved surface 231b of the upper frame portion 231 and then moves above the inner wall surface 21a of the peripheral wall 21 along the curved surface 231b.
The movement of the air AR, which has collided with the lower frame portion 232 and becomes turbulent, to the standby space 50 side is prevented, and the discomfort and discomfort of the player waiting in the standby space 50 can be reduced.

  Further, as shown in FIG. 4B, the pair of side frame portions 233 and 233 provided on both sides in the width direction of the opening portion 22 are also on the side that becomes the other side toward the distal ends 233a and 233a on the opening side. The front end 233a and 233a are curved in a direction in which the opening diameter D2 between the frame and the frame portion becomes narrower, and the front ends 233a and 233a are positioned in the standby space 50 outside the peripheral wall 21, and are opposed to the other side frame portion. The portions are curved portions 233b and 233b.

  Therefore, when the air AR moving upward from below in the floating space 20 collides with the curved portions 233b and 233b of the side frame portions 233 and 233, the air AR smoothly flows along the surfaces of the curved portions 233b and 233b. Since it flows, generation | occurrence | production of a turbulent flow can be prevented suitably.

  Further, the upper frame portion 231 and the side frame portion 233 in the frame portion 23 where the player M enters and exits are curved with the respective leading ends 231a and 233a positioned on the standby space 50 side ((b in FIG. 5). The curved surface 231b in FIG. 4B and the curved portion 233b in FIG. 4B) Even if the player M collides with the curved surface during the game, the impact of the collision is alleviated and the player M is safe. Secured.

As shown in FIG. 4A, the standby space 50 is provided in a limited range on the lower side of the floating space 20 with respect to the floor surface 201 of the floating space 20, and the peripheral wall surrounding the floating space 20 21 and the ceiling portion 56 of the standby space 50 are each made of a transparent member (for example, laminated glass or acrylic resin).
Therefore, a player who waits for the next game order in the standby space 50 can easily see the state of the player M floating in the floating space 20 through the peripheral wall 21 and the ceiling portion 56 formed of a transparent member.
In the embodiment, the ceiling portion 56 of the standby space 50 is also a floor portion of the second floor portion of the skydiving simulator 1, and the visitor stands on the ceiling portion 56 of the standby space 50. Yes. Therefore, the visitor can visually recognize the state of the player M floating in the floating space 20 from above through the ceiling portion 56 formed of a transparent member.

As shown in FIGS. 4A and 4C, a plurality of lighting devices (LED devices 211) are provided on the peripheral wall 21 surrounding the floating space 20 over the entire circumference of the peripheral wall 21. Yes. The plurality of LED devices 211 are provided within the thickness of the peripheral wall 21 with the light emitting surface 211 a facing the floating space 20.
Note that the LED device 211 does not penetrate the peripheral wall 21 to the floating space 20 side, and the peripheral wall 21 is left by a predetermined thickness H3 between the LED device 211 and the floating space 20 (FIG. 4). (See (c)).

  Here, if the LED device 211 is provided so as to protrude from the inner wall surface 21a of the peripheral wall 21 into the floating space 20, the flow of the air AR that moves in the vicinity of the inner wall surface 21a of the peripheral wall 21 from below to the LED Blocked by device 211. On the other hand, when the LED device 211 is provided on the outer wall surface 21b of the peripheral wall 21, the light emitted from the light emitting surface 211a of the LED device 211 is diffusely reflected within the thickness of the peripheral wall 21 formed of a transparent member. 211 cannot properly illuminate the floating space 20.

  In the embodiment, the LED device 211 is provided within the thickness of the peripheral wall 21, and the peripheral wall 21 having a predetermined thickness H3 is left between the light emitting surface 211a of the LED device 211 and the floating space 20. . Therefore, the LED device 211 does not protrude into the floating space 20, and the LED device 211 does not hinder the flow of the air AR that moves in the vicinity of the inner wall surface 21a.

  Further, the thickness H3 of the peripheral wall 21 at the position where the LED device 211 is provided is thinner than the thickness H4 of the other peripheral walls 21 (H3 <H4). Therefore, the light emitted from the light emitting surface 211a of the LED device 211 can easily pass through the peripheral wall 21 having the thickness H3 and appropriately illuminate the floating space 20.

[Decompression space]
Next, the decompression space 57 provided adjacent to the standby space 50 will be described.
As shown in FIG. 1, the diameter of the floating space 20 as viewed from above is set to be the smallest in the first vertical wind tunnel 12. Therefore, in the floating space 20, the air velocity of the air AR moving from below to above in the floating space 20 becomes the fastest, and the air pressure in the floating space 20 and the standby space 50 communicating with the floating space 20 is the first vertical. It becomes lower than the atmospheric pressure (atmospheric pressure) outside the wind tunnel 12. Therefore, when the player M suddenly comes out of the first vertical wind tunnel 12 (under atmospheric pressure environment) from the floating space 20 or the standby space 50, the change in atmospheric pressure inside and outside the standby space 50 becomes large. As a result, you may feel uncomfortable.

Therefore, as shown in FIGS. 4A and 4B, in the skydiving simulator 1, the atmospheric pressure inside and outside the standby space 50 when the player M enters and leaves the standby space 50 (floating space 20). In order to make this change smooth, a decompression space 57 is provided between the standby space 50 and the outside of the first vertical wind tunnel 12.
The decompression space 57 is hermetically partitioned by the outer wall 52 and the inner wall 53 of the standby space 50.

  The inner wall 53 is a wall that partitions the decompression space 57 and the standby space 50. The inner wall 33 is provided with a pressure-resistant door 54 that connects / disconnects the decompression space 57 and the standby space 50. The outer wall 52 is a wall that partitions the decompression space 57 and the space outside the first vertical wind tunnel 12. The outer wall 52 communicates / not communicates the decompression space 57 and the space outside the first vertical wind tunnel 12. A pressure-resistant door 55 is provided for communication.

  Therefore, the decompression space 57 is airtightly isolated from the standby space 50 and the space outside the first vertical wind tunnel 12 by the pressure resistant doors 54 and 55, and when both the pressure resistant doors 54 and 55 are closed. The atmospheric pressure in the decompression space 57 is kept constant.

In the skydiving simulator 1, the pressure-resistant doors 54 and 55 are controlled not to open at the same time so that the air in the standby space 50 does not leak to the outside of the first vertical wind tunnel 12 through the decompression space 57. ing.
For example, when a player who has finished playing first comes out of the first vertical wind tunnel 12 from the standby space 50, the player can use the other pressure door while the one pressure door 55 is closed. 54 is opened to enter the decompression space 57. Then, after closing the other pressure-resistant door 54, the pressure in the decompression space 57 is gradually increased to the pressure outside the first vertical wind tunnel 12 (atmospheric pressure). Thereafter, with the other pressure-resistant door 54 closed, the player M opens one pressure-resistant door 55 and comes out of the first vertical wind tunnel 12.
Therefore, the player M gets used to the outside of the first vertical wind tunnel 12 after being accustomed to the atmospheric pressure difference between the standby space 50 (floating space 20) and the atmospheric pressure. Can reduce the sense of discomfort.

As described above, in the skydiving simulator 1, one pressure-resistant door 55 is always closed while the other pressure-resistant door 54 is opened.
Therefore, when a player who has finished playing first goes out of the first vertical wind tunnel 12 from the standby space 50, the standby space 50 and the outside of the first vertical wind tunnel 12 do not communicate directly with each other. The air in the space 50 does not leak outside the first vertical wind tunnel 12.
Therefore, the player who waits for the next game can play the next game without being affected by the exit from the standby space 50 of the player who has finished playing first.

  A plurality (two in the embodiment) of pressure regulating valves 571 are arranged on the outer wall 52 and the inner wall 53 that partition the decompression space 57, and the air pressure in the decompression space 57 becomes a predetermined value or more. The pressure regulating valve 571 is operated to reduce the pressure in the decompression space 57 to a set value. This prevents the decompression space 57 from being pressurized too much.

Then, when a player who waits for the next game enters the standby space 50 from the outside of the first vertical wind tunnel 12, the player opens one pressure door 55 with the other pressure door 54 closed. Open and enter decompression space 57. Then, after closing one pressure-resistant door 55, the pressure in the decompression space 57 is gradually reduced from atmospheric pressure to substantially the same pressure as the pressure in the floating space 20. Thereafter, in a state where one pressure door 55 is closed, the player M opens the other pressure door 54 and enters the standby space 50.
Therefore, since the player M gets used to the atmospheric pressure difference between the standby space 50 and the outside of the first vertical wind tunnel 12 and then enters the standby space 50, the player M caused by a sudden change in atmospheric pressure. The feeling of discomfort can be reduced.

As described above, in the skydiving simulator 1, while the one pressure door 55 is open, the other pressure door 54 is always closed.
Therefore, the standby space 50 and the outside of the first vertical wind tunnel 12 do not directly communicate with each other, so that the air in the standby space 50 does not leak out of the first vertical wind tunnel 12.
Therefore, the player who has played the game first can continue playing without being influenced by the player entering the standby space 50 waiting for the next game.

[Cooling ventilation equipment]
The cooling ventilation device 60 is heated by frictional heat with the inner wall surface of the annular wind tunnel 10 while circulating the annular wind tunnel 10 while switching the air AR flowing through the annular wind tunnel 10 and fresh air outside the annular wind tunnel 10. This is a device for cooling the air AR.

  As shown in FIG. 1, the cooling ventilator 60 is provided on the upper wall 14a1 of the first horizontal wind tunnel 14a. The cooling ventilator 60 is configured to be able to open and close a part of the upper wall 14a1, and discharges the old air AR flowing in the annular wind tunnel 10 to the atmosphere (see arrow A in FIG. 1), and at the same time fresh from the atmosphere. Air can be taken into the annular wind tunnel 10 (see arrow B in FIG. 1).

As described above, the cooling ventilator 60 releases the air AR flowing in the annular wind tunnel 10 to the atmosphere and takes in fresh air from the atmosphere into the annular wind tunnel 10, thereby warming up while circulating in the annular wind tunnel 10. A function of cooling the temperature of the air AR.
In addition, ventilation in the annular wind tunnel 10 by the cooling ventilator 60 is performed not only while the game is being performed by the player M but also when the game is not being performed. In that case, since it is not necessary for the blowers 30a and 30b to send the air speed AR for the player M to float, the blowers 30a and 30b can be ventilated at a low rotation speed. The noise of the blower can be reduced.

[Operation of Skydiving Simulator]
Next, operation | movement of the sky diving simulator 1 is demonstrated according to the movement of the air AR sent out from the air blower 30. FIG.

  As shown in FIG. 1, first, in the skydiving simulator 1, the air AR sent from the blowers 30 a and 30 b of the second vertical wind tunnels 13 a and 13 b is moved along the circulation path 11 formed in the annular wind tunnel 10. It is designed to circulate.

  When the engines (or motors) of the blowers 30a and 30b are driven, the fans 30a1 and 30b1 of the blowers 30a and 30b rotate around the rotation axis. The air AR sucked from 32b is sent out from the other discharge ports 31a and 31b at a pressure higher than that of the suction.

  The air AR sent from the blowers 30a and 30b moves downward in the second vertical wind tunnels 13a and 13b. These air ARs have their moving directions changed by travel direction changing members 41 and 43 installed so as to cross the flow path cross section of the air AR below the second vertical wind tunnels 13a and 13b. The direction changes by about 90 °), and moves in the second horizontal wind tunnel 14b toward the first vertical wind tunnel 12 (see flow paths A1 and A2 in FIG. 1).

  Next, each air AR moving from the second vertical wind tunnel 13a side and the 13b side into the second horizontal wind tunnel 14b toward the first vertical wind tunnel 12 side is converted into the air AR in the second horizontal wind tunnel 14b. The traveling direction is changed by the traveling direction changing members 46 and 47 provided so as to cross the cross section of the flow path, and merges and moves upward in the first vertical wind tunnel 12.

  The air AR that moves upward in the first vertical wind tunnel 12 passes through a rectifier 481 that is provided so as to cross the cross-section of the flow path in the enlarged diameter portion 48 after the wind speed is reduced in the enlarged diameter portion 48. Is rectified.

The air AR is rectified by the rectifier 481 and then sent to the reduced diameter portion 49 (confuser). The air AR sent to the reduced diameter portion 49 is moved upward in the floating space 20 from the lower side after the wind speed is increased while passing through the reduced diameter portion 49.
Therefore, the player M in the floating space 20 can float in the floating space 20 due to the wind pressure of the air AR moving from below to above.

Since the enlarged diameter portion 203 is provided on the upper portion 202 side of the floating space 20, the wind speed of the air AR becomes slower as the air AR moves upward of the floating space 20.
Therefore, if the player M ascends to the upper part 202 of the floating space 20, the air AR does not become a wind speed enough to cause the player M to collide with the traveling direction changing members 44 and 45. Therefore, the traveling direction of the player M A collision with the changing members 44 and 45 can be prevented.

  Then, the air AR that moves upward in the floating space 20 beyond the enlarged diameter portion 203 is disposed so as to cross the cross section of the air AR at the upper part of the first vertical wind tunnel 12. 44, 45 in a direction to move in the first horizontal wind tunnel 14a toward the second vertical wind tunnel 13a and in a direction to move in the first horizontal wind tunnel 14a toward the second vertical wind tunnel 13b. Divided.

Then, the air AR moving in the first horizontal wind tunnel 14a toward the second vertical wind tunnel 13a is moved in the direction in which the second vertical wind tunnel 13a is moved downward by the traveling direction changing member 40. After the moving direction is changed, the air is sucked from the suction port 32a of the blower 30a provided in the second vertical wind tunnel 13a.
Further, the air AR moving in the first horizontal wind tunnel 14a toward the second vertical wind tunnel 13b is moved in the direction in which the second vertical wind tunnel 13b is moved downward by the traveling direction changing member 42. After the moving direction is changed, the air is sucked from the suction port 32b of the blower 30b provided in the second vertical wind tunnel 13b.

  As described above, each air AR sent from the blowers 30 a and 30 b moves along the circulation path 11 in the annular wind tunnel 10.

  As described above, in the embodiment, the floating space 20 is set at an intermediate position in the longitudinal direction of the cylindrical vertical wind tunnel (first vertical wind tunnel 12), and the floating space 20 moves upward from below. In the skydiving simulator that floats the player M in the floating space 20 by the flow of the air AR, the player M can enter and leave the floating space 20 at a position corresponding to the floating space 20 of the first vertical wind tunnel 12. Of the first vertical wind tunnel 12 that surrounds the opening 22 (frame portion 23) on the downstream side in the flow direction of the air AR in the floating space 20. The downstream edge portion (upper frame portion 231) along the circumferential direction of the vertical wind tunnel 12 has an opening diameter between the downstream lower frame portion 232 and the upstream edge 231a of the downstream upper frame portion 231. D1 is narrow Is curved in a direction, the front end 231a of the downstream side of the upper frame portion 231, and a structure that is located outside of the first vertical wind tunnel 12.

  Here, when the upper frame portion 231 on the downstream side of the frame portion 23 is not curved, the air AR that collides with the lower frame portion 232 and becomes a turbulent flow collides with the tip 231a of the upper frame portion 231. Thus, it diffuses into the floating space 20 and the standby space 50. Then, the turbulent flow diffused in the floating space 20 gives a sense of incongruity to the player in the floating space 20, and the turbulent flow diffused in the standby space 50 gives minute vibrations to the air in the standby space 50. It gives a sense of incongruity to the players who are waiting inside.

Constructed as described above, the upper frame portion 231 on the downstream side of the opening portion 22 is curved in such a direction that the opening diameter between the upper frame portion 231 and the lower frame portion 232 becomes narrower toward the tip 231a side of the upper frame portion 231. Therefore, most of the turbulent flow generated in the lower frame part 232 can be moved along the curved surface 231 b of the upper frame part 231 and guided to the downstream side of the floating space 20.
Thereby, since the spreading | diffusion in the floating space 20 of the turbulent flow which generate | occur | produced in the upper frame part 231 of the opening part 22 can be prevented suitably, the discomfort which the player M who is playing with the sky diving simulator 1 has can be reduced. .

  In addition, a reduced diameter portion 49 whose flow path cross-sectional area becomes narrower toward the floating space 20 is provided below the floating space 20 in the first vertical wind tunnel 12. A rectifier 481 configured by arranging cylindrical members 482 in parallel is provided, and in each of the rectifiers 481, each of the cylindrical members 482 opens an opening 482a of the cylindrical member 482 in the flow direction of the air AR in the first vertical wind tunnel. It was set as the structure provided in the direction along.

  With this configuration, the air after the traveling direction is adjusted by the rectifier 481 is sent to the floating space 20, so that the player feels uncomfortable as compared to the case where turbulent air is sent to the floating space 20. And can reduce discomfort.

  Further, the opening 482a of the cylindrical member 482 has a hexagonal shape in a cross-sectional view, and the rectifier 481 has a configuration in which each of the plurality of cylindrical members 482 is disposed in close contact with each other without gaps. did.

  When the hexagonal tubular member 482 is employed, the tubular members 482 can be disposed in close contact with each other without gaps, and thus the air resistance of the rectifier 481 can be reduced. Therefore, more air can be rectified efficiently.

  Further, the first vertical wind tunnel 12 in which the floating space 20 is set, the second vertical wind tunnels 13a and 13b parallel to the first vertical wind tunnel 12, the first vertical wind tunnel 12 and the second vertical wind tunnel 13a, 13b, a lower horizontal wind tunnel (second horizontal wind tunnel 14b) for guiding the air sent from the blowers 30a and 30b to the first vertical wind tunnel 12, and the first vertical wind tunnel 12 and the second vertical wind tunnel 12. An upper horizontal wind tunnel (first horizontal wind tunnel 14a) that is connected to the upper part of the vertical wind tunnels 13a and 13b and guides the air flowing through the first vertical wind tunnel 12 to the second vertical wind tunnels 13a and 13b. An air circulation path 11 is formed, and moves in the second horizontal wind tunnel 14b toward the first vertical wind tunnel 12 at least at a connecting portion between the first vertical wind tunnel 12 and the second horizontal wind tunnel 14b. The traveling direction of the air to be moved is changed to the first vertical wind tunnel 12 Traveling direction changing member 47 for changing the direction of movement toward the floating space 20 has a configuration provided.

  If comprised in this way, the advancing direction of the air which moves in the 2nd horizontal wind tunnel 14b toward the 1st vertical wind tunnel 12 is efficient in the direction which moves in the 1st vertical wind tunnel 12 toward the floating space 20. Can change well.

  In the traveling direction changing members 46 and 47, a plurality of plate-like base materials (blade members 41a) are provided at intervals in the thickness direction of the blade member 41a, and each of the blade members 41a includes a blade member. The center part of the width direction of 41a was made into the structure which comprised the curved shape offset from the line segment which ties the both sides of the said width direction.

  If comprised in this way, air will move smoothly along the blade member 41a formed in the curved shape, and the advancing direction of air will be changed efficiently.

  Further, the central portion of the blade member 41a is a thick portion formed thicker than both sides in the width direction of the blade member 41a. The thick portion has a cooling fluid (in the longitudinal direction of the blade member 41a). The flow path (hole 41a2) of coolant (coolant or the like) is formed.

  When the coolant flows through the hole 41a2 of the blade member 41a, the entire blade member 41a is cooled. Then, while the air heated by the frictional heat with the inner wall surface of the horizontal wind tunnel or the vertical wind tunnel can change the traveling direction along the blade member 41a, heat exchange is performed between the air and the cooled blade member 41a. This is done to ensure that the air temperature is cooled to a temperature suitable for play.

  In addition, a plurality of lighting devices (LED devices) are provided within the thickness of the first vertical wind tunnel 12 (the peripheral wall 21 surrounding the floating space 20) corresponding to the floating space 20.

  If comprised in this way, since the some LED apparatus 211 is provided in the thickness of the surrounding wall 21 surrounding the floating space 20, while the inside of the floating space 20 can be reliably illuminated with the LED apparatus 211, the thickness of the surrounding wall 21 is sufficient. The reflection of light inside can be suppressed.
