Description

TECHNICAL FIELD The present invention relates to stadiums for basketball, volleyball, futsal, and the like, and more specifically, technology related to stadiums capable of selectively carrying out various sports.

Basketball, volleyball, badminton and the like are usually played in facilities such as sports arenas and gymnasiums (hereinafter referred to as "indoor sports facilities"). This facility for indoor games is rarely used as a dedicated facility for only playing a specific game (for example, only basketball), and is generally used for playing a wide variety of games.

Of course, each competition has different rules, different competition spaces, and different competition lines. For example, in basketball, in addition to the center line, side lines, and end lines, there are also center circles, free-throw lines, and 3-point lines. Volleyball also has a center line, side lines, end lines, and an attack line. Similarly, futsal, badminton, handball and indoor tennis will all have their own lines.

Since the lines on the court differ depending on the competition, the lines of the previous competition are removed or camouflaged each time the competition type is changed, and new lines are added for the next competition (hereinafter referred to as " "Court change work".) was necessary. In addition, there is a risk that the floor surface will be damaged when changing courts, and because it takes time and effort, there is the problem that different types of competition cannot be held in a short period of time (for example, on the same day). Therefore, there has been a strong demand for a technique that enables more efficient court change work when changing the type of sport. Therefore, techniques have been proposed so far that can omit the work of changing courts. For example, Patent Document 1 proposes a multi-purpose sports facility in which various competition courts are provided in advance in one area. there is

Japanese Patent Application Laid-Open No. 2006-142010

The multi-purpose sports facility disclosed in Patent Document 1 has a track and field track, a 5-a-side football court, a volleyball court, a basketball court, and the like arranged in the same facility. A line corresponding to each competition is attached in advance. Therefore, this multi-purpose sports facility can host multiple types of sports without having to change courts. However, the area occupied by a variety of courts naturally increases, and in other words, a vast amount of land is required to construct the courts. not. In addition, because the facility is so vast, the target competition court is located far away from the spectator seats, which can be pointed out as a problem that it is extremely difficult for the spectators to watch the game.

The object of the present invention is to solve the problems of the prior art, that is, it does not require a large land area unlike the multi-purpose sports facility of Patent Document 1, and the court change work (removal and new installation of lines) is not required. To provide a stadium that can be changed to a different type of competition court without any changes.

The present invention has been developed with a focus on providing a storage space for storing individual competition courts, and making it possible to move the individual competition courts between the competition area and the storage space. This is an invention based on an idea that has never existed before.

The stadium of the present invention has a competition area in which competitions are held, and is provided with a base base, elevating rails, a competition board hangar, and individual competition boards. Of these, the base base is arranged in the competition area, and the elevating rail is arranged in the competition area and can move up and down. In addition, the competition board hangar is a storage space adjacent to the competition area, and the individual competition boards are placed on fixed rails in the competition board hangar and can slide on the fixed rails in a substantially horizontal direction (including horizontal). It is a thing. In addition, on the upper surface of the individual competition board, an individual competition court with competition lines is provided. When the elevating rails are raised to the height of the fixed rails, the elevating rails are connected to the fixed rails, whereby the individual competition board slides on the elevating rails toward the competition area.

The playing field of the present invention can also have a plurality of individual playing boards. In this case, a plurality of stages of fixed rails are arranged vertically in the game board hangar, and individual game boards having individual game courts of different types are placed on the fixed rails. Then, by raising the elevating rail to the height of the fixed rail on which the desired individual game board is placed, the desired individual game board slides toward the game area.

In the stadium of the present invention, the game board hangar may consist of a right board hangar and a left board hangar. Note that the right competition board hangar is adjacent to one side of the competition area, and the left competition board storage is adjacent to the other side of the competition area. In this case, the individual board also consists of a right individual board and a left individual board. The right individual board is placed on the fixed rail of the right board hangar, while the left individual board It is placed on the fixed rail of the board hangar. Then, the right individual game board and the left individual game board slide on the elevating rail so as to approach each other.

The stadium of the invention of the present application may further include a base plate lifting device for lifting and lowering the base plate.

The stadium of the present invention can also be provided with a court for individual competitions on the upper surface of the base base.

The stadium of the present invention can also be provided with a lower chord material on the individual competition board. In addition, this lower chord member is provided on the lower surface of the individual competition board in a substantially vertical direction (including vertical direction) of the elevating rail.

The stadium of the present invention has the following effects.
(1) A wide variety of competitions can be held at one competition facility.
(2) Since it is possible to change to a competition court of a different type without performing court change work (remove and install lines), it is possible to prepare for the next competition in a short period of time.
(3) Since it can be built in the same area as the conventional one, that is, it does not require a large land area as in Patent Document 1, construction costs will not rise and it will be difficult to watch the game from the spectator seats. be able to.

An example of an embodiment of the stadium of the present invention will be described based on the drawings.

FIG. 1 is a plan view schematically showing a stadium 100 of the invention of the present application, and FIG. 2 is a sectional view schematically showing the stadium 100 of the invention of the present application. As shown in FIG. 1, the stadium 100 of the present invention has a competition area GA formed in the center, and audience stands ST are installed around the competition area GA. A competition board hangar 200 is formed inside the stand ST. Also, as shown in FIG. 2, the stadium 100 includes elevating rails 300 and a base board 400 arranged in the competition area GA, and an individual board 600 stored in the board hangar 200. Further, the base board 400 It is also possible to have a base bottom plate lifting device 500 arranged below.

The individual competition board 600 has an individual competition court with a predetermined competition line attached to its upper surface, that is, it is a floor exclusively used for that competition. For example, an individual game board provided with a basketball court is of course used exclusively for basketball, and an individual game board provided with a futsal court is of course used exclusively for futsal. The individual competition board 600 is configured to slide substantially horizontally (including horizontally) on the elevating rails 300, and the competition can be carried out by moving to the competition area GA. For the sake of convenience, the direction in which the individual competition board 600 slides will be referred to as the "main axis direction", and the direction orthogonal to the main axis direction will be referred to as the "perpendicular direction to the main axis".

If two or more individual game boards 600 are stored in the game board hangar 200 and different types of individual game courts are provided, it is possible to carry out a plurality of types of games, which is preferable. In this case, as shown in FIG. 2, it is preferable to store the individual competition boards 600 in two or more stages (four stages in the figure) in the competition board storage 200 . The individual game boards 600 stored in multiple stages can be put in and taken out individually like the drawers of a chest of drawers. Of course, the configuration is not limited to the multi-stage arrangement, and the competition board hangar 200 can be configured to store one type of individual competition board 600 (that is, in one stage).

In FIGS. 1 and 2, a left game board hangar 200L is formed on one side (left side in the figure) adjacent to the game area GA, and a right game board hangar 200R is formed on the other side (right side in the figure) adjacent to the game area GA. formed. The left individual game board 600L is stored in the left game board storage 200L, and the right individual game board 600R is stored in the right game board storage 200R. That is, the game board hangar 200 is composed of the left game board hangar 200L and the right game board hangar 200R, and the individual game board 600 consists of the left individual game board 600L and the right individual game board 600R. In this case, the left individual competition board 600L and the right individual competition board 600R are slid to approach each other and use the individual competition court formed in the competition area GA. The stadium 100 according to the present invention is not limited to the examples shown in FIGS. 1 and 2, and the competition board hangar 200 may be formed only on one side adjacent to the competition area GA. In this case, the game board hangar 200 stores the individual game board 600 in its entirety (that is, not divided into left and right), and this individual game board 600 slides to the game area GA.

Hereinafter, each main element constituting the stadium 100 of the present invention will be described in detail. For the sake of convenience, an example in which the game board hangar 200 is composed of a left game board hangar 200L and a right game board hangar 200R and each of the game board hangars 200 stores four stages of individual game boards 600 will be described. .

(Competition board hangar and fixed rail)
FIG. 3 is a partial sectional view schematically showing the game board storage 200, showing only the left game board storage 200L for the sake of convenience. As shown in this figure, the competition board hangar 200 is a hollow storage space formed inside the audience stand ST. 610 is installed. The fixed rails 610 are substantially horizontal (including horizontal) and are arranged in the direction of the main axis. It is better to arrange them in the above columns. Alternatively, a plate-shaped fixed rail 610 may be arranged. However, since the individual competition board 600 slides on the fixed rail 610 toward the center (that is, toward the competition area GA), the upper surface of the fixed rail 610 (the contact surface with the individual competition board 600) has a small coefficient of friction ( Slippery) materials or rollers (for example, rollers) may be used.

(Individual competition board)
The individual competition board 600 is plate-shaped, and has an individual competition court on its upper surface as described above. FIG. 4 is a plan view showing an example of an individual game board 600 provided with an individual game court. (a) is an individual game board 600a for handball provided with a handball court, and (b) is a futsal game board. (c) is a volleyball individual competition board 600c provided with a volleyball court, (d) is a basketball individual competition board 600d provided with a basketball court, ( e) is an omni-court individual game board 600e provided with an artificial turf tennis court, and (f) is a clay tennis individual game board 600f provided with a clay tennis court. If a plurality of individual competition boards 600 as shown in FIG. 4 are prepared, a wide variety of competitions can be held. Also, like the omni-court individual competition board 600e and the clay tennis individual competition board 600f, even if the competition courts are the same, by changing the material (grass and clay, etc.), it is possible to increase the selection of competition events. can also The competition courts shown in FIG. 4 are merely examples, and the individual competition board 600 can naturally be provided with all kinds of competition courts such as table tennis and badminton.

5A and 5B are diagrams schematically showing the individual competition board 600, in which (a) is a cross-sectional view of a part cut in the direction of the main axis, and (b) is a cross-sectional view of half of it cut in the direction perpendicular to the main axis. . As shown in this figure, the individual game board 600 has a thin floor board material 620, and the upper surface of this floor board material 620 is provided with an individual game court. Since an individual competition court usually requires a relatively large area, it is preferable to form the entire surface by connecting a plurality of floor board materials 620 as shown in FIG. 5(a). Further, since the floor plate member 620 is thin, it is likely to be bent. Further, for reinforcement, a lower chord member 650 extending in the direction perpendicular to the main shaft can be stretched under the floor plate member 620 (for example, under the support beam 630). Since the individual game board 600 slides while the support base 640 is placed on the fixed rail 610 or the elevating rail 300, at least the lower surface of the support base 640 (the contact surface with the elevating rail 300, etc.) has a friction coefficient of It is recommended to use materials with low (slippery) slipperiness (e.g., rigid style foam, etc.).

(lifting rail)
The elevating rail 300 is used to slide the individual game board 600 to the game area GA, and is configured to be vertically movable (that is, elevate). In raising and lowering the elevating rail 300, a winch or the like arranged above, a jack or the like arranged below, or various conventional techniques can be used. Similarly to the fixed rails 610, the elevating rails 300 are preferably arranged in two rows so as to be aligned in the direction perpendicular to the main axis in order to support the individual competition board 600. FIG. Furthermore, since the individual competition board 600 slides on the elevating rail 300, the upper surface of the elevating rail 300 (the contact surface with the individual competition board 600) uses a material with a small coefficient of friction (easily slippery) like the fixed rail 610. do it.

Here, a procedure for sliding the individual game board 600 using the elevating rails 300 will be described with reference to FIGS. 6 and 7. FIG. 6 and 7 are step diagrams for explaining the sliding movement of the individual game board 600 using the elevating rails 300. FIG. 6 is a sectional view and FIG. 7 is a plan view. First, as shown in FIG. 6A, the elevating rail 300 is raised. Then, as shown in FIG. 6(b), the lift is stopped at the height of the fixed rail 610 on which the intended individual competition board 600 is placed. Here, futsal is to be played, so the elevating rail 300 rises to the individual competition board 600e for the omni court (equipped with an artificial turf tennis court) located on the second stage from the top and stops there. At this time, it is preferable to adjust the stopping height of the lifting rail 300 so that the height of the top surface of the lifting rail 300 and the height of the top surface of the fixed rail 610 substantially match (or match).

When the elevating rail 300 stops at a predetermined height and the upper surface of the elevating rail 300 and the upper surface of the fixed rail 610 are connected, as shown in FIGS. 600e is slid in the central direction (that is, toward the competition area GA). More specifically, the omni-court individual competition board 600 e slides so as to be gradually transferred from the fixed rail 610 to the elevating rail 300 . In order to slide the individual competition board 600, various conventional techniques such as roller chains, jacks, and winches can be used.

As shown in FIG. 7A, when the omni-court individual competition boards 600e are slid toward each other on the left and right elevating rails, they come into contact with each other near the center. As a result, a futsal court is formed in the competition area GA as shown in FIG. 7(b).

(Foundation base and base base lifting device)
As shown in FIG. 8, the base base 400 is a plate-like floor member arranged in the competition area GA, and can support the individual competition board 600 from below. The base base 400 can also be used for individual competitions, in which case an individual competition court is provided on the upper surface. It should be noted that the base base 400 is desirably a floor member that is relatively harder than the individual game board 600, and therefore a basketball court that is played on a hard floor surface is preferably provided on the upper surface of the base base 400.

The base base 400 shown in FIG. 8(a) is located below the audience stand ST, so spectators watch the individual competitions held on the individual competition base 600 (or the base base 400) placed on the base base 400. hard to do Therefore, it is preferable to provide a base plate elevating device 500 for raising and lowering the base plate 400 . As shown in FIG. 8, the base plate elevating device 500 is arranged below the base plate 400, and is capable of lifting and lowering the base plate 400 by means of, for example, a jack. As shown in FIG. 8(b), the spectator can use the individual competition board 600 (or the base board 400) by raising the base board 400 to a predetermined height (the highest position in the figure) using the base board lifting device 500. It will be easier to watch the individual competitions held at

(Example of use)
Next, a usage example of the stadium 100 of the present invention will be described with reference to FIGS. 9 and 10. FIG. FIG. 9 is a cross-sectional step diagram showing the procedure for pulling out the left and right individual competition boards 600 from the state in which the elevating rails 300 are placed on the level of the base base 400, and FIG. FIG. 10 is a step diagram showing, in sectional views, a procedure from a state in which the two are in contact with each other near the center to a state in which an individual competition can be performed.

In FIG. 9(a), the elevating rail 300 is arranged at the level of the foundation base plate 400. In FIG. Therefore, as shown in FIG. 9B, the elevating rail 300 is raised to the height of the fixed rail 610 on which the target individual competition board 600 is placed. When the upper surface of the lifting rail 300 and the upper surface of the fixed rail 610 are connected, as shown in FIG. to the center (to the left in the figure).

In FIG. 10(d), the right end of the left individual game board 600L and the left end of the right individual game board 600R abut within the game area GA and stop sliding. However, since the individual competition board 600 in this state is supported only by the elevating rails 300, it is rather unstable to compete on its upper surface. Therefore, as shown in FIG. 10( e ), it is preferable to raise the basic bottom board 400 by the basic bottom board lifting device 500 and firmly support the individual competition board 600 with the raised basic bottom board 400 . Alternatively, as shown in FIG. 10(f), the individual competition board 600 can be lowered by the elevating rails 300, and the individual competition board 600 that has been lowered can be firmly supported by the base base board 400.

When the competition ends, the left individual competition board 600L is stored in the left competition board storage 200L and the right individual competition board 600R is stored in the right competition board storage 200R by performing the reverse procedure described above.

The stadium of the present invention can be effectively used in facilities for various sports such as basketball, volleyball, badminton, futsal, and indoor tennis.
