Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a method for raising and lowering a ball-proof body provided along a fence for partitioning a competition field and a spectator seat of a ball game field that performs various ball games (such as rugby and football) mainly for baseball, and the same The present invention relates to a lifting device.

Technical background

In recent years, in baseball-based ball games that are installed outdoors and indoors, fences that divide the competition field and spectator seats are designed so that the audience can experience the realism of ball games as much as possible. The ball-proof net installed in a fixed state on the top is removed. In particular, the fence in proximity to the infield field (about 1m) is formed lower than the fence in the outfield field (about 7m), so that you can get a feeling of being able to participate in ball games from the same viewpoint as a ball player. To prevent this, ball-proof nets are being removed at many ballparks.

In ball games, especially baseball, the ball often jumps over the fence into the spectator's seat. In this case, the ball that jumps over the infield field over the proximity fence is overwhelming compared to the ball that jumps over the fence in the outfield field. Many.

Furthermore, as part of the service, since the audience seats are open to the audience from practice before the game, the ball often jumps into the audience seats.

In the case of a baseball game, there are a large number of elementary school children and young children in the audience seats, and there is a tendency for children to gather in order to see the players more closely, especially near the fence.

Problems to be solved by the invention

However, the fence that excludes the above-mentioned conventional ball-proof nets may directly hit the children when the ball jumps directly into the spectator seat, and there is a danger. The child should always watch the game under the guardian. In addition, there is a problem that it is impossible to fully experience the realism of the game.

In addition, when a person with a physical disability is invited to watch a game, or when children such as elementary school students are invited to watch a game, there is a method of placing a staff member to eliminate the danger from a direct jumping ball. However, there is a drawback in that it is not always possible to sufficiently eliminate the danger, and it is expensive to arrange the staff.

Accordingly, an object of the present invention is to provide a method and an apparatus for raising and lowering a ball-proof body in a ball game field that can provide a sense of realism and can take a ball-proof measure in preparation for all cases.

Means for solving the problem

In order to achieve the above object, the present invention provides a ball-proof body that can be raised and lowered along a fence for partitioning a playing field and a spectator seat in a ball game field, and the ball-proof body is located below the upper end of the fence when stored. It is located in, and it is provided so that only a predetermined distance may be raised / lowered from the upper end part of a fence at the time of suspension installation.

In the ball-proof body provided along the fence for partitioning the competition field and the spectator seat in the ball game field, the ball-proof body is configured to be movable up and down via a winch wire along the support, and when the ball-proof body is stored. It is configured to be positioned below the upper end of the fence.

Action and effect

The operation and effect of the present invention will be described. When a game is started in a baseball field, mainly the baseball field, the upper end of the ball-proof body is usually stored below the upper end of the fence along the fence that separates the ball field and the spectator seat. Use it so that the audience can fully enjoy the presence.

However, if there are many people with physical disabilities or small children coming to the audience, depending on the height of only a part of the fence or the surrounding fence, for example, depending on the height of the child The ball-proof body is set up from the fence to prevent the ball from directly hitting the children so that the game can be enjoyed safely.

Also, if you want the spectators to watch the pre-game exercises, the ball-proof body is raised (for example, the height that protects the entire spectator seat) so that more balls can jump over the fence and enter the spectator seat. ) Eliminating the danger of a ball that jumps directly and moves up, players can practice with peace of mind, and spectators can watch the practice safely.

In this way, safety is ensured by raising and lowering the ball-proof body and adjusting the height of the ball-proof body according to the situation (contents of use, age of the audience, etc.) and the actual purpose, which is the original purpose. You can experience the feeling.

Moreover, since the raising / lowering method of a ball-proof body can also be adjusted freely, it can respond | correspond freely according to each ball game field.

Embodiment

An embodiment of the ball-ball raising / lowering method and apparatus thereof according to the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic explanatory perspective view showing a lifting device for a ball-proof body in one embodiment of the present invention, FIG. 2 is a schematic side view showing a state in which the lifting device for the ball-proof body is lifted, and FIG. FIG. 4 is a schematic explanatory perspective view showing another embodiment of the method for raising and lowering the ball-proof body, FIG. 4 shows another embodiment of the method for raising and lowering the ball-proof body, (A) is a schematic explanatory plan view, and (B) is a schematic front view. It is.

First, the ball-proof body lifting apparatus 1 according to the present invention includes a game field 2 of a ball game field that is mainly used for outdoor and indoor baseballs (others are considered to be a circu, rugby, American football, etc., and are actually used). It is provided inside the fence 4 that partitions the spectator seat side 3. The installation location is not limited to the inside of the fence 4 and can be provided integrally with the fence 4.

The basic structure of the ball-proof body lifting / lowering device 1 includes a support 5 provided on the fence 4 (the support 5 can be fixed or liftable), and a winch wire 6 that is driven vertically along the support 5. The endless winch 7 provided on the winch wire 6 and the ball-proof net as the ball-proof body 8 provided between the columns 5 are configured. The endless winch 7 and the ball-proof net 8 as the driven ball-proof body 8 may be manually operated or automatically operated according to the length of the ball-proof net, and are previously lifted and lowered via a control panel (not shown). It is also possible to set the height of the supporting column 5 and the range in which the ball-proof body 8 that moves up and down is suspended.

The ball-proof body lifting apparatus 1 of the present invention has the above-described configuration. Next, the use of the ball-proof body lifting apparatus 1 will be described.

First, the ball-proof body lifting / lowering device 1 is installed on the fence 4 with the ball-proof body 8 stored therein.

In this state, since the upper end of the ball-proof body 8 is positioned below the fence 4, the spectator can experience the realism of the game without the ball-proof body 8 blocking the field of view.

However, when the ball-proof body 8 is required, the ball-proof body 8 is installed at the required place (the fence 4 portion).

In order to install the ball-proof body 8, first, the endless winch 7 is actuated in accordance with instructions from the control panel and the winch wire 6 is driven to rotate along the column 5, whereby the ball-proof body 8 is moved along the column 5 to a predetermined height.
