Abstract

PURPOSE: To keep a floating swimmer within a prescribed swimming range even when the floating swimmer reaches the upper limit or lower limit in a height direction without being able to use vertical movement well by detecting the state in a swimming state detection means and adjusting a rising air flow speed based on the result. CONSTITUTION: By blowers 2 and 3, a rising air flow for floating a human body against gravity is formed inside a wind tunnel 1 in a vertical cylindrical shape. Then, in the swimming state detection means 10 and 11, it is detected that the floating swimmer reaches the position of a set upper limit H set in the height direction in a space for swimming and the floating swimmer reaches the position of a set lower limit L. Further, in an air flow speed control means 12, in order to keep the floating swimmer who reaches the position of the set upper and lower limits H and L within the prescribed swimming range, based on the detected result of the means 10 and 11, the rising air flow speed inside the wind tunnel 1 is automatically lowered at the time of detecting that the floating swimmer reaches the position of the upper limit H and the rising air flow speed inside the wind tunnel is automatically accelerated at the time of detecting that a person reaches the position of the lower limit L.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a game device.

[Conventional technology]

2. Description of the Related Art Skydiving training devices are conventionally known in which a high-speed updraft is created in a vertical cylindrical wind tunnel by a blowing device to lift a human body against gravity, and the trainee is made to levitate within the wind tunnel.

[Problem that the invention seeks to solve]

However, in this skydiving training device, the surfacing swimmer (trainer) moves up and down ('f1 swimming height adjustment) by changing the pressure area of the body against the updraft by stretching or contracting the body and limbs. However, for the average person without training, it is extremely difficult to move up and down by changing the pressure-receiving area of the body in this way, leading to the risk of losing balance and falling or being blown away. There is a risk of an accident due to sudden jumps, and although this skydiving training device offers a thrill, it cannot be used as a recreational device that the general public can easily enjoy due to safety reasons. .

Therefore, as a safety measure, it is conceivable to install safety nets at the top and bottom of the swimming space in the wind tunnel, but as mentioned above, ordinary people who are unable to go up and down will immediately place safety nets in either the top or bottom. It is difficult to maintain a levitation swimming state even though the purpose is to entertain levitation swimming, so it is not suitable for general public. It is still insufficient as a game device.

The purpose of the present invention is to provide a way for ordinary people to fully experience the feeling of aerial swimming by adding reasonable additional means to conventional training equipment.
Moreover, it is possible to provide a game device that can be enjoyed safely.

[Means for solving problems]

Features of the play device according to the present invention include a vertical cylindrical wind tunnel whose internal space is used as a swimming space, and a blower device that forms in the wind tunnel an upward air current that causes the human body to float against gravity. that the floating swimmer has reached a set upper limit position set in the height direction in the swimming space with respect to the device body;
and a swimming state detection means for detecting that the levitation swimmer has reached a set lower limit position, and a swimming state detection means for detecting that the levitation swimmer has reached the set upper and lower limit positions, so as to keep the levitation swimmer within a predetermined swimming range. Based on the detection results, when it is detected that the levitating swimmer has reached the upper limit position, the updraft velocity in the wind tunnel is automatically reduced, and when it is detected that the levitation swimmer has reached the lower limit position, the wind tunnel The reason is that an airflow speed control means for automatically increasing the rising airflow speed within the airflow system is added, and its functions and effects are as follows.

[For production]

In other words, even if a floating player fails to ascend and descend properly and reaches the upper or lower limit set in the height direction, the swimming state detection means detects such a state and adjusts the airflow velocity based on the detection result. By automatically increasing or decreasing the updraft velocity as described above by the control means, the floating swimmer is automatically kept within a predetermined swimming range.

〔Effect of the invention〕

Therefore, even if a levitated swimmer loses his/her balance and falls, or is blown away and suddenly rises, he or she will not deviate from the predetermined swimming range, and accidents caused by such falls or sudden rises will be prevented.

Furthermore, since the levitation swimmer is automatically kept within a predetermined swimming range, the levitation swimmer can continue to maintain the levitation swimming state.

As a result of the above, even ordinary people without training can continue to enjoy the feeling of floating in the air within a designated swimming range and fully and safely, making a completely new type of entertainment device called aerial swimming available to the general public. It has now become widely available.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

A straight cylindrical wind tunnel (1) is installed in a vertical position, and this wind tunnel (1)
The discharge port of the air supply chamber (2) is connected to the lower end of the air supply chamber (2), and an axial flow fan (3) is installed at the air intake port (2a) of the air supply chamber (2).
3), by supplying air from the air supply chamber (2) into the wind tunnel (1), a high-speed upward air current is formed in the wind tunnel (1) that causes the human body to float against gravity.

In other words, the interior space of the wind tunnel (1) is used as a swimming space, and the players inside the wind tunnel (1) are floated up by high-speed updrafts.
This is a game device that allows the floating player to enjoy the feeling of floating in the air.

In the wind tunnel (1), the players are levitating and swimming in the surrounding seats (
4) It is made of transparent material so that it can be seen from above.

At the upper part of the wind tunnel (1), a part of the hopper (5) is connected, the diameter of which is larger on the exhaust port (5a) side at the upper end.

Safety nets (6) and (7) are installed at the lower end of the wind tunnel (1) and at the upper end of the hopper part (5) (5a), and the safety net (6) at the lower end of the wind tunnel is It also serves as a rectifier for rectifying the rising air current in the wind tunnel (1) as well as the landing floor for the player.

The air supply chamber (2) is a noise reduction chamber,
A sound absorbing material (8) is attached to the chamber wall, and a guide vane (9) is attached to the part where the wind direction is changed.

In the swimming space inside the wind tunnel (1), the upper limit (H) is the border position between the wind tunnel (1) and part of the hopper (5), and the position is several meters higher than the lower safety net (6). Lower limit (L
), and for that range setting, the upper limit (
) an infrared type upper limit sensor (10) that detects that the lower limit (L) has been reached, and an infrared type lower limit sensor (11) that detects that the lower limit (L) has been reached.
), and the upper and lower limit sensors (10),
Based on the detection results of (li), the upper limit (
When it is detected that the updraft speed has reached the current speed, the updraft speed is decreased by the set width from the current speed, and the lower limit (L
) is detected, the fan (
3) A controller (12) is provided to automatically adjust the air blowing capacity.

In other words, the levitation swimmer adjusts the pressure area of his body against the updraft by stretching or contracting his body and limbs, and also by operating the mobile remote controller (described later) in the wind tunnel (1). Although it is possible to go up and down (swimming height adjustment) by oneself, floating swimmers within the set swimming range (X) are likely to reach the upper limit (H) or lower limit (L) and deviate from the set swimming range (X). When this occurs, the controller (12) adjusts the airflow speed as described above based on the detection results of the upper and lower limit sensors (10) and (11) to automatically move the floating swimmer closer to the center of the set swimming range (X). By doing so, the floating swimmer can safely and continuously fully enjoy the floating state in the set swimming range (X).

Note that the fan blowing capacity adjustment for adjusting the airflow speed by the controller (12) is specifically performed by adjusting the rotation speed of the fan (3) by inverter control.

In addition, the controller (12) has the above-mentioned upper and lower limit sensor (
10) In addition to the airflow velocity control for preventing deviation from the range based on the detection results in (11), the following controls (a) to (d) are also performed.

(b) Remote controller carried by the player (13
), the blowing capacity of the fan (3) is adjusted so that the speed of the rising air corresponds to the speed specified by the player.

In other words, with this control, levitation swimmers can hold the tongue controller in a fixed position without having to perform delicate and difficult operations such as adjusting the pressure-receiving area of the body by extending or contracting the body or limbs. (13) allows you to freely move up and down (swimming height adjustment).

The remote controller (13) is equipped with an ascent start switch and a landing switch, in addition to the height adjuster for adjusting the airflow velocity as described above in the ascent swimming state, and when the ascent start switch is turned on, Based on the transmitted command, the controller (12) starts the operation of the fan (3) and adjusts the air blowing capacity so as to gradually increase the ascending air velocity. The player starts floating and slowly rises to within the set swimming range (X).

Also, when a player in a floating state turns on the landing switch, the controller (12) slowly reduces the updraft speed from the current speed based on the transmitted command, and finally stops the fan (3). The air blowing capacity is adjusted so that the floating swimmer slowly descends and lands on the lower safety net (6).

In addition, when a floating swimmer descending by turning on the landing switch passes the lower limit (L) of the set swimming range (X), the airflow speed is adjusted to prevent deviation from the range based on the detection result of the lower limit sensor (11). Although a control priority relationship is set so that the automatic increase in airflow velocity is not executed, the upper and lower limit sensor (10) responds to transmission commands from the remote controller (13) other than the landing operation.

The airflow velocity adjustment control for preventing deviation from the range based on the detection result of (11) is executed with priority.

In the figure, (14) is a receiver that receives command signals from the remote controller (13).

(b) Swimmer position (swimming height) within the set swimming range (X)
Based on the information from the group of swimming height sensors (15) that detect the swimming height, the air blowing capacity of the fan (3) is controlled so as to detect the ascending and descending speed of the floating swimmer and limit the detected speed to a specified safe speed. Add automatic correction to.

In other words, depending on this control, when a floating swimmer ascends or descends due to a change in the pressure receiving area against the updraft (regardless of whether it is a conscious adjustment or an unconscious change), the
Airflow speed (fan blowing capacity) to limit lifting speed
In addition to automatically adjusting the airflow velocity, the airflow velocity is also controlled when the floating swimmer is raised or lowered by adjusting the airflow velocity, so that the speed of elevation due to the airflow velocity adjustment is limited. The rate of change (adjusted rate of change in fan blowing capacity) is limited.

Each swimming height sensor (15) has the same configuration as the upper and lower limit sensors (10) and (11) described above,
These are infrared sensors that detect the presence or absence of floating swimmers at the installation height, and are arranged in large numbers at equal pitches in the height direction within the set swimming range (X).

(c) The airflow velocity (
Automatically adjusts fan ventilation capacity.

In other words, through this control, the levitation swimming state is changed in addition to the lifting and lowering by the levitation swimmer's own operation, thereby increasing the fun of the levitation device.

Of course, the upper and lower limit sensors (10)
, Range deviation prevention control based on the detection result of (11),
Elevation speed limit control based on information from the swimming height sensor group (15) and landing control based on commands from the remote controller (13) are given priority over this automatic swimming height change control.

In the figure (16), in this swimming height automatic change control,
This is an automatic command device that gives an airflow speed change command to the controller (12) based on a programmed airflow speed change pattern.

(d) Adjust the airflow velocity in response to commands from an operator who monitors and manages the operation of this amusement device.

In other words, if the player cannot operate the remote controller (13) or if a dangerous situation occurs, the operator will give priority to the control panel (17) outside the wind tunnel (1). This allows for easy driving operation.

Note that the operator gives various instructions to the player through wireless headphones worn by the player.

[Another example]

(1) As a swimming state detecting means for detecting whether the floating swimmer has reached the upper limit or the lower limit, an ultrasonic sensor may be used instead of the infrared upper limit sensor or lower limit sensor as in the above embodiment. , various types can be applied,
Further, sensors for detecting the distance in the height direction from the levitation swimmer are provided at the upper and lower ends of the wind tunnel, and based on the distance detection, it is determined that the levitation swimmer has reached the upper and lower limits. Also good.

(It) Automatically adjusts the updraft velocity when the levitation swimmer reaches the upper limit, based on the detection result of the swimming state detection means, so that the levitation swimmer who has reached the upper or lower limit stays within a predetermined swimming range. In order to automatically increase the updraft speed when it reaches the lower limit, instead of adjusting the updraft speed by adjusting the fan's air blowing capacity by controlling the rotation speed or vane angle, etc. It may also be implemented by controlling the opening degree of the damper for adjusting the air volume.

(III) The amount of decrease in the updraft velocity when the number of levitation swimmers reaches the upper limit, and the increase in the updraft velocity when the number of levitation swimmers reaches the lower limit, respectively. It is sufficient to appropriately set a value that can be kept within a predetermined swimming range.

Alternatively, instead of simply decreasing or increasing the updraft speed, when the floating swimmer reaches the upper or lower limit, the updraft speed is reduced or increased for the duration of the setting, and then the updraft speed is returned to the original speed value. It may be possible to return the airflow to the side only to a certain extent.Furthermore, instead of setting the extent of decrease and increase in updraft speed as absolute values, it may be set as a ratio to the speed at which the decrease and increase are performed. You may also do so.

(■) As mentioned above, the specific control structure for automatically decreasing and automatically increasing the updraft velocity based on the detection result of the swimming state detection means can adopt various configurations, and these control structures are collectively referred to as airflow. It is called speed control means.

(V) The first set swimming range as shown in the above embodiment.
and a second range that includes it,
With respect to each of the first set swimming range and the second set swimming range, the airflow speed is adjusted to prevent deviation from the range by the airflow speed control means based on the detection result of the swimming state detection means. It may also be possible to ensure safety.

(Vl) Various improvements can be made to the specific shape and structure of the wind tunnel and blower, the type of fan that makes up the blower, and the detailed structure of the safety net and the entrance and exit structure for the wind tunnel. Alternatively, a heating configuration for supplying hot air may be added.

(■) Although the game device according to the present invention is mainly intended for play by untrained people, it can also be applied to training skydivers, and is particularly suitable for training beginners.
