Description

Screen baseball game system having vertical pitching machine}

The present invention relates to a screen baseball game system using a pitching machine. More specifically, it allows the game to be played by throwing the ball in the direction where the batter is standing and hitting the ball, but the speed and pitch type of the ball can be varied in various ways during pitching. A screen baseball using a pitching machine that allows you to enjoy the game by supplying and pitching balls manually or automatically, but when automatic, pitching is provided sequentially or randomly, with pitch types and velocity selected in various forms. It's about the game system.

Recently, as the baseball population has increased, the so-called screen baseball system has emerged, which overcomes the limitations of playing actual baseball in a large baseball stadium and allows you to play baseball virtually while feeling the realism of the baseball game even in a small indoor space.

Typically, a screen baseball system installs a screen that can display a virtual baseball field and a batting box where users can place bets in an indoor space of a predetermined size, and a pitching machine installed behind the screen pitches the ball toward the batting box. A user preparing to hit a ball at bat hits a ball pitched from a pitching machine, and at this time, the sensing device senses the movement of the pitched ball and the ball hit by the user and determines whether the ball is a strike or not based on the sensing results. It determines whether it is recognized or not and implements a simulation image of the trajectory of the ball hit on the screen.

The screen baseball system as described above is a method in which a hole is drilled on a screen on which a baseball simulation image is projected, and a pitching machine installed on the back of the screen pitches the ball to the batter's box through the hole formed on the screen.

You may consider applying this screen baseball system for professional batting practice to analyze actual baseball players' batting posture and batted balls, but in the case of the conventional screen baseball system, it is impossible to bat on a ball fixed to a specific position, so batting posture There is a problem that confirmation and correction are difficult.

In addition, in the case of the conventional screen baseball system, since the sensing of the movement of the hit ball is not accurate, it is impossible to accurately predict the distance, direction, altitude, trajectory, etc. of the hit ball, which makes professional hit analysis difficult.

Therefore, as previously disclosed in Republic of Korea Patent Publication No. 10-1999203, a screen baseball practice system and its management using an automated batting practice device configured to facilitate the batter's batting practice by automatically placing the ball on the tee. A system is provided.

However, in the screen baseball practice system as described above, there were limitations in the cameras configured to only photograph the horizontal and vertical trajectories of the ball and to photograph and analyze the posture of the batter hitting the ball.

In addition, the automated batting practice device provided in the screen baseball practice system is installed separately from the floor, so it takes up a lot of narrow indoor space, and there was a problem that it became an obstacle when the batter moved from the hitting position to another position. .

In addition, in the pitching machine of the automated batting practice device provided in the screen baseball practice system as described above, the rotation speed of the pitching wheels cannot be adjusted, so pitching is always performed at a constant speed, and it is impossible to vary the pitching control. Therefore, because the pitch type is always constant, pitching practice is bound to be monotonous, and even if it is possible to change the velocity and type of the ball, it has to be performed manually by pressing the corresponding button at the time of pitching each time to change them, which is cumbersome in use. .

First, it should be noted that among the drawings, identical components or parts are indicated by identical reference numerals. Additionally, in describing the present invention, detailed descriptions of related well-known functions or configurations will be omitted in order to make the gist of the present invention unambiguous.

In an indoor screen baseball game hall, the posture of the batter hitting the ball can be filmed and corrected, and the ball is fired vertically from the floor to the top to hit the ball. The pitching machine is buried in the floor, making space efficient. As shown in FIGS. 1 to 10, the screen baseball game system using a pitching machine according to an embodiment of the present invention that can be utilized includes a pitching machine 10, a ball feeder 20, a ball collector 30, It consists of a first camera 40, a second camera 50, a control unit 60, an image transmitter 70, a screen 80, and a remote control 90.

The pitching machine 10 launches the ball in a vertical direction to a position where it can be hit so that the batter can hit it, and is installed buried in the lower part of the floor.

At this time, the height at which the ball is launched is determined by the rotational speed of the tossing machine 11, which will be explained below, and the rotational speed of the tossing machine 11 is adjusted by the control unit 60 so that the ball is launched at various heights corresponding to the height of the batter. ) is controlled through.

As described above, the ball launched in the vertical direction through the pitching machine 10 falls in a parabola from the highest rising point, and because it draws a parabola in the vertical direction, the time it remains in the air becomes somewhat longer.

Therefore, the batsman can catch the ball while it is in the air and hit it as an RBI, thereby improving the ease of hitting and improving the enjoyment of the baseball game.

In addition, it is possible for the batter to hit the ball with an upper swing method, which involves swinging upwards from the bottom when the ball rises or falls, making hitting more fun.

The pitching machine 10 as described above makes it possible to shoot the ball upward through various implementations.

First, looking at an example of the pitching machine 10, as shown in FIGS. 2 to 4, the toss machine 11, the rotation speed controller 12, the ball toss guide piece 13, and the ball upward guide plate 14 ) is composed of.

The toss machine 11 rotates through the rotation speed controller 12 controlled by the control unit 60 to move the ball along the movement path 11-1 and causes the ball to shoot upward through its rotational force.

The rotational force of the toss machine 11 is generated at the speed input to the control unit 60 corresponding to the height at which it is launched upward, that is, the area from the knee to the chest, which is the strike zone in baseball.

The rotation speed controller 12 is controlled through the control unit 60 or the remote controller 90 to control the rotation speed of the toaster 11.

The ball toss guide piece 13 is mounted at a predetermined interval on one side of the rotation direction of the toss machine 11 and serves to guide the balls to be launched through the discharge port 15 by the rotational force of the toss machine 11. do.

In addition, the bolt guide piece 13 is installed to be movable left and right through an adjustment screw 13-1 and is appropriately adjusted in response to the movement of the ball along the movement path 11-1.

The ball upward guide plate 14 is installed in the strike zone of the batting box and has a discharge port 15 through which the ball fired upward through the toss machine 11 passes through and is discharged into the hitting area.

In addition, the ball upward guide plate 14 is provided with a safety sensor 14-1 that controls the system not to operate when looking into the discharge port 15 to check for malfunction of ball discharge, thereby preventing unexpected accidents. It was possible to prevent it in advance.

Looking at another example of the pitching machine 10, as shown in FIG. 5, the toss machine 11, the rotation speed controller 12, the toss guide member 16, the vertical movement guide member 17, and the ball upward It consists of a guide plate (14) and a ball delivery member (18).

The toss machine 11, the rotation speed controller 12, and the ball upward guide plate 14 have been described in detail through the above example of the implementation of the pitching machine 10, and detailed descriptions thereof are omitted here. I decided to do it.

The toss maker 11 rotates through the control unit 60 to rotate and move the ball, and the rotation speed controller 12 is controlled through the control unit 60 to control the rotation speed of the toss maker 11. The ball upward guide plate 14 is provided with a discharge port 15 and is installed in the strike zone of the batting box so that the ball fired upward through the toss machine 11 penetrates and is discharged into the hitting area. It plays a role.

The toss guide member 16 is mounted at the end and has a concave shape that prevents the ball from escaping, and is provided with a holding member 16-1 that allows the ball to enter the concave portion and be seated and supported. It is mounted on the machine (11) to guide the movement of the ball and to shoot it upward through the discharge port (15).

In addition, the toss guide member 16 rotates by the rotation of the toss machine 11 to enable the holding member 16-1 to catch the ball in the ball delivery member 18.

The vertical movement guide member 17 is controlled to move up and down through the control unit 60, and serves to guide the ball moved through the toss guide member 16 to rise vertically through the discharge port 15.

That is, the upward movement guide member 17 is provided with a moving piece 17-1, and the moving piece 17-1 moves downward at the same time as the tossing machine 11 rotates to move the toss guide member 16. By blocking the rotation path of the ball, it temporarily prevents rotation, causing the ball to bounce upward toward the discharge port (15).

In other words, as the toss machine 11 rotates, the toss guide member 16 also rotates and the ball in the holding member 16-1 also rotates, and the downwardly moved moving piece 17-1 performs the toss. When the guide member 16 blocks the rotation path and prevents rotation at the same time, the ball escapes the holding member 16-1 and is launched to the discharge port 15 due to the rotational inertia force, using the principle of upward movement.

The ball delivery member 18 receives balls from the ball supplier 20, temporarily supports them, and then provides the balls to the holding member 16-1.

That is, the ball transmission member 18 allows the holding member 16-1 of the toss guide member 16, which has been rotating after supporting the ball, to momentarily catch the ball, and at the same time, the holding member 16-1 1) Move to the right so as not to interfere with the rotation.
