Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-pressure training facility that can provide the same environment as high-altitude training even on flat ground and in urban areas.

[0002]

2. Description of the Related Art In the recent sports world, which is required to have higher physical abilities, training under low pressure and low oxygen environment (so-called high altitude training) requires oxygen supply capability to each cell in the body. It has attracted attention because it can be used in conditions that are high and especially competitive on level ground where endurance is required. In particular, in the long-distance terrestrial field, attention has been paid to the above reasons, and high-altitude training, which is training under low pressure and low oxygen, has been largely adopted.

[0003] However, the adaptation reaction to the human environment varies from person to person. In addition, even in the same person, the adaptation reaction changes depending on the health condition, psychological condition, and the like at that time. In other words, the adaptive response to low pressure and low oxygen environment in high altitude training may bring not only positive factors but also negative factors such as low temperature, low humidity, and high solar radiation to competitiveness.

[0004] Further, the places where high-altitude training is performed are generally so-called remote areas, and may be almost isolated. There are not a few psychological changes in humans caused by such changes in the social environment. In view of costs such as travel expenses and stay expenses, high-altitude training is currently a training method limited to top-class elite players.

Moreover, it is said that the effect of high-altitude training can be maintained for only about 10 days to two weeks when descending on a flat ground. Is in a difficult situation. From the above circumstances, artificial high-altitude training is performed by creating a decompressed state so that the same effect can be expected without going to the site (high altitude), and training at high altitude using low-pressure training facilities Proposals that maintain the effects over a long period of time and enable the player to enter the competition in an ideal state are disclosed in, for example, Japanese Patent Application Laid-Open Nos. 4-313277 and 8-112373, and belong to the public domain.

However, conventionally known facilities are shown in FIGS.
As exemplified in FIG. 2, the equipment is small enough that at most several people can fly or jump.

[0007]

As described above, sports training at high altitudes is said to increase the ability of the body to adapt and take in oxygen into the body, which is effective in improving endurance and the like. Although high-altitude training is conducted mainly for long-distance events in competitions, it is difficult for ordinary athletes to reach in terms of cost of moving and staying places and safety measures.

Therefore, a conventionally known low-pressure training facility has been created. However, the conventional facility creates a low-pressure training room having a strength capable of withstanding a pressure of about 5 to 7 t / m ² generated on the outer wall due to a difference between an external pressure and an internal pressure. Therefore, it was not possible to make a large enough to actually run around, and it was not useful for conducting comprehensive training such as long distance athletics. Furthermore, the content was not sufficient in terms of safety against fire and the like and strength enough to withstand negative force due to reduced pressure.

Accordingly, an object of the present invention is to provide a low pressure, low oxygen state space for a large number of persons by joining various movable cylindrical tubular units and tubular curved unit units and joining them. A training course that is large enough to be used, and large and long enough to be used for a variety of sports training needs and is sufficient for ordinary living areas such as flatlands and urban areas. The purpose of the present invention is to provide a low-pressure training facility that can be installed in accordance with high-altitude training.

[0010]

According to the first aspect of the present invention, there is provided a low-pressure training facility in which a cylindrical tubular unit having good airtightness is joined to form a tunnel-like training course having a sufficiently long distance. Yes, a low-pressure or low-oxygen environment near a high altitude is created by combining a low-pressure and low-oxygen environment control system with the training course.

According to a second aspect of the present invention, there is provided a low-pressure training facility, wherein the cylindrical tubular unit forming the training course according to the first aspect is supported on the ground by supporting legs. In combination, a training course having a three-dimensional shape that is free in up, down, left, and right directions is created. The low-pressure training facility according to the third aspect of the present invention is provided with a training course according to any one of the first and second aspects, wherein a disaster prevention and safety system against fires in the course, poor physical condition of the user, and other accidents are provided. It is characterized by having been done.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the illustrated embodiments and examples of the present invention will be described. The basic configuration of the present invention is, as exemplified in the drawings, various combinations of a cylindrical tubular unit 2 (FIG. 4) and a tubular curved unit 3 having a circular cross section (FIGS. 6 and 7). ), A training course 4 (FIG. 1,
3) and a building D having a machine room 6 provided with a low-pressure control system and a low-oxygen environment control system, a management room 11 for watching equipment and users, a locker room 8, a lobby 9, and the like (FIG. 1).

FIGS. 1 and 3 are views from above of a low-pressure training facility 1 in which a training course 4 including moderate ups and downs on a flat ground has been created. In this training course 4, the cylindrical tubular units 2 illustrated in FIG. 4 are connected in series as shown in FIG. 5, or combined with the tubular curved unit 3 having a circular cross section as shown in FIG. The training course 4 resembling a track in a stadium or a cross-country course as shown in FIG. 1 or FIG. 3, ie, a tunnel-like shape that changes up and down or includes curves to the right and left. The training course 4 is created, and the low-pressure training facility 1 is configured.

The inclination angle of the tube-shaped bending unit 3 is set to 15
When the angle is set to ゜, as shown in FIG. 7, the gradient in the up-down direction can be freely changed depending on the number of the tube-shaped curved portion units 3, so that an ascending or descending course with an inclination angle of 15 ° can be created. In addition, as shown in FIG. 6A, when four pieces are combined, a corner that bends 60 degrees horizontally can be formed, and when one piece is used, a curve that bends 15 degrees horizontally can be formed as shown in FIG. 6B, thereby creating various training courses. be able to. In addition, when the tube-shaped curved unit 3 is used, the upper and lower parts can be used.
It is also easy to create a training course with a three-dimensional curved slope on the left and right.

A cylindrical tubular unit 2 constituting a training course 4 of the low-pressure training facility 1
Is manufactured with a cross section (circular) diameter of about 5 m and an axial length of about 30 m as an example. As a manufacturing means, as shown in FIG. 4, a plurality of curved surface plate members 2a equivalent to a plurality of divided cylindrical shapes are combined in a circular shape, and a sealing material 2b is used at each joint between the curved surface plate members 2a. A method in which the bolts 2c and the nuts 2d are strongly tightened for joining is preferably employed. As a method of supporting each tubular unit 2, a support leg 7 is installed and supported on the ground. By changing the height of each support leg 7 by expanding and contracting it as shown in FIGS. 2 and 7, a training course 4 of a pseudo cross-country with up and down can be easily formed.

FIG. 5 shows a method of connecting a series of tubular units 2 and a curved tube unit 3 in the axial direction.
As shown in, the sealing material 2e is sandwiched between the joints,
A method in which the inside is decompressed and the concave and convex surfaces of each other are adsorbed and inserted is suitably performed. As shown in FIG. 2B, a cross section of the training course 4 is provided with a duct space S below the road surface 5, and ducts and wires necessary for the training course 4 are stored and arranged therein. If the tube material above the runway surface 5 is made of a transparent material such as glass or an acrylic resin plate, it is convenient for the user to train while enjoying the surrounding scenery.

By controlling the low-pressure, low-oxygen environment control system in the machine room 6, the atmospheric pressure and other environments in the training course 4 can be freely changed according to the intensity and progress of exercise. Depending on the degree of low pressure (or low oxygen), a front room 10 is provided between the building D and the course as a means for avoiding giving a sudden change in the environment to the human body. By gradually getting used to the physical condition by the front room 10 and entering the training course 4 and training,
Exercise equipment in a form that considers further safety can be provided. The method of using the anterior room 10 is to gradually change the air pressure over time with a dial, to shift from the atmospheric pressure of the outside air to the low pressure in the course, and to enter the training course 4 when the body is used. Conversely, when going out of the training course 4, the front room 10 is first set to the same pressure as the inside of the training course 4, and after entering the front room 10 from the training course 4, the dial is gradually used to increase the pressure. It changes and moves from the low pressure in the training course to the pressure of the outside air, and goes out when the body is used. By the presence of such an anterior room 10, it is possible to enter and exit the training course 4 without changing the air pressure in the training course 4 by pointing.

In the management room 11, the health status of the runner (user) M can be monitored by the monitoring TV camera 14 (FIG. 9) provided in the training course 4. Further, it is also possible to use the speaker 15 to call out and send an instruction. A record display panel 19 for automatically displaying the real-time record of the runner (user) M may be provided to help update the record of the runner (user) M (see FIG. 9).

In the management room 11, the sprinkler 12, the smoke detector 13, the monitoring TV, and the like are prepared in case of a fire or an accident inside the training course 4 in consideration of safety in the training course 4. A camera 14, an emergency speaker 15, an oxygen mask 16 connected to an oxygen cylinder 22, an exit direction sign 18 and an emergency electric vehicle 17 are provided (see FIG. 9). For example, if a fire occurs in training course 4,
The smoke is detected by the smoke detector 13 and the surveillance TV camera 14, and evacuation is guided from the management room 11 by an emergency broadcast using the speaker 15. In order to avoid panic, an exit direction sign 18 is provided to indicate which direction is closer to the exit. When the occurrence of a fire is confirmed, the fire extinguishing water pumped up from the fire extinguishing water tank 24 by the sprinkler pump 23 is discharged by the activated sprinkler 12 to extinguish the fire. If the runner (user) M becomes sick or has another accident, the oxygen is replenished using the nearest oxygen mask 16 for recovery. In a further emergency, the emergency electric vehicle 17 is dispatched and rescued.

Next, the air conditioning in the facility will be described. In order to control the inside of the training course 4 to a low pressure and low oxygen environment, a filter 26 for purifying outside air and a hot water coil 27 for adjusting humidity are provided in front of the ventilation fan 25. Further, in order to control the inside of the training course 4 to a low oxygen environment, by mixing it with the outside air together with the outside air containing nitrogen from the nitrogen generator 28, the proportion of oxygen contained in the air is reduced to create a low oxygen environment. . Further, in order to control the inside of the training course 4 to a low pressure environment, the pressure difference in the training course 4 is reduced by changing the output difference between the ventilation fan 25 and the exhaust fan 21 (increase the proportion of exhaust), and the target air pressure is set. , The outputs of the ventilation fan 25 and the exhaust fan 21 are made the same to create a constant low-pressure environment.

The outside air inlet 30 and the nitrogen generator 2
In front of the exhaust gas 8 and the exhaust fan 21, the switching valve 29 prevents gas (outside air, nitrogen or inside air) from flowing back. Since the facility has a tunnel structure with a large scale, as shown in FIG.
1 is provided to allow the inside air to flow and assist ventilation. By creating such a flow of air, the training course 4 has a relatively stable low-pressure or low-oxygen environment throughout the year under constant conditions. Therefore, the temperature and humidity control should be performed only for heating and humidification in winter. I do.

Finally, repair will be described. The conventional low-pressure training facility has a configuration in which the components are integrated into the entire space, so that if one location is damaged, the damage will extend to the entirety. However, the low-pressure training facility 1 of the present invention
Is configured as a combination of the tubular unit 2 and the tubular curved unit 3 as described above, and each unit is configured by the curved plate member 2a, the sealing material 2c, the bolt 2b, and the nut 2d. If one part is damaged, the repair is performed by replacing only the damaged unit or member, which is very advantageous in terms of cost. Also, when assembling and disassembling, it can be easily performed as compared with the conventional low-pressure training facility, and the cost is low.

[0023]

According to the low-pressure training facility of the present invention, the same training as high-altitude training can be performed at a low cost as needed even in a normal flat ground living area near an urban area or the like. In addition, since training is performed in a normal living area on a flat ground, it can be used in combination with other facilities (normal training facilities, accommodation facilities, and the like), and more effective training can be expected.

Furthermore, training in an ideal environment becomes possible by eliminating the adverse effects (low temperature, low humidity, low steam, high solar radiation, psychological loneliness, etc.) accompanying high altitude training. Also, the biggest drawback of conventional low-pressure training rooms is that large facilities that can actually run are practically impossible, or even if theoretically possible, it is difficult to realize in terms of cost. What was,
ADVANTAGE OF THE INVENTION According to this invention, there is a decisive big difference in that a practice similar to an actual competition can be performed without using a pseudo running device such as a running machine, and a greater training effect can be obtained. In addition, as a result of the facility being installed on a large scale, it is possible to compete with training partners.

From the shape of the cylindrical tubular unit,
Mechanically advantageous strength is also considered in that the force applied to the outer wall can be evenly received on the entire outer wall,
It is also excellent in safety.
