  • the present invention relates to a ball game-related training system. More specifically, the present invention relates to a ball game-related training system to supply or shoot the ball to allow the player to practice a variety of ball games practices, including kicking or shooting the ball on the play field, hitting the ball falling onto the play field by a hand for a spike type attack, and receiving and shooting the ball over the air by a hand.
  • Patent Document 1 Japanese Patent Application Laid-Open No. H9-276463 (published on October 28, 1997 ) tilted as "Ball shooting apparatus” (hereinafter referred to as Patent Document 1) and U.S. Patent No. 8,371,964 B2 (issued on February 12, 2013 ) tilted as "Volleyball spiking training device" (hereinafter referred to as "Patent Document 2”) are disclosed.
  • Patent Document 1 a ball is inserted between two pitching rollers rotated by two motors, and the ball is fired by the rotational force of the pitching rollers. Therefore, there is a problem that the shooting angle is not constant when using repeatedly the apparatus. Further, there is an inconvenience that many balls fired must be manually collected and put in a ball container. In addition, the ball shooting apparatus described in Patent Document 1 is not suitable for practicing various ball games since the ball is shot in a straight line at a relatively high position from the apparatus.
  • the foot volleyball is a ball game that originated from Korea.
  • a net is set up between the two teams' courts, and the team uses their head and feet to pass the ball to the opponent's team.
  • the ball is inserted between the two pitching rollers, and the ball is fired forward by the pitching rollers. Therefore, there is a problem that the ball hits the net directly.
  • this apparatus is very expensive and is not suitable for general sports activities. This problem applies equally to a volleyball game having the similar game rules to the foot volleyball.
  • the ball shooting apparatus disclosed in Patent Document 1 only the horizontal direction in which the ball is blown and the angle of inclination of the shot ball may be adjusted.
  • this shooting apparatus is not suitable for basketballs where that the players grab and toss the aerial ball falling vertically from above the play field to the floor, volleyballs where the players hit the aerial ball falling vertically from above the play field to the floor using the hand, and the foot volleyballs where the players hit the aerial ball falling vertically from above the play field to the floor using a foot.
  • the volleyball spike training system as disclosed in the patent document 2 comprises a ball holder and an optional net.
  • the training holder comprises a wheeled chassis supporting a vertical stanchion projecting upwardly that supports a hopper and a ball feeding apparatus.
  • the stanchion includes a crank system for vertically adjusting telescoped stanchion segments.
  • Balls dropping from the hopper travel by gravity down an inclined ramp at the top of the frame towards a discharge throat. Balls travelling down the ramp are indexed by a Z-shaped lever that serially separates them.
  • a pair of downwardly projecting hands, one fixed and one pivoted, receive dropping balls and temporarily hold them for shooting. The pivoting hand controls the indexing lever to jam successive balls when the device is loaded.
  • the present disclosure has been made in order to solve the above problems.
  • the present disclosure is aimed to providing a ball shooting apparatus that automatically fires the training ball toward a pre-standardized play field for various ball games such as soccer, futsal, foot volleyball, volleyball, basketball, etc., and a ball collection apparatus which automatically collects the training ball fired into the play field and automatically supplies the collected training ball to the ball shooting apparatus, so that the ball game may be practiced more easily with minimum cost and time.
  • Another object of the present invention is to provide a ball game-related training system configured to detect the movement of a player on the play field and fire a ball towards a position associated with the sensed movement to allow the player to practice the ball receive operation, or to dropping the ball from above the play field onto a bottom to allow the player to practice the ball spike attack.
  • Still another object of the present invention is to provide a ball game-related training system including a ball shooting apparatus capable of shooting the training ball in various directions using a hydraulic actuator cylinder, and a ball collection device that automatically collects the ball launched into the play field at the corner or at the middle region of the end line or at the end line on the play field and automatically supplies the ball to the ball shooting apparatus.
  • Still another object of the present invention is to provide a ball game-related training system including a ball supply apparatus that falls down the ball downward from above the play field onto the bottom, to allow the player to hit the ball by a hand or foot or handing it over the net to the opposing court.
  • Still another object of the present invention is to provide a ball game-related training system including a ball shooting apparatus for detecting a player's movement on the play field and firing the ball at regular intervals in the motion detection direction, or for launching a ball based on detection of a player's predetermined movement type.
  • Still another object of the present invention is to provide a ball game-related training system including a ball shooting apparatus to shoot the ball by striking the ball that is seated in the distal end of an elongate hollow shooting tube via the action of a hydraulic actuator cylinder operated at high pressure by a hydraulic accumulator.
  • Still another object of the present invention is to provide a ball game-related training system including a score counter to assign and display a scored based on a ball passing-through sub-region in a rectangular region defined by the rectangular goalpost installed on the football play field or the futsal play field, thereby maximizing the exercise effect and inducing exercise interest.
  • Still another object of the present invention is to provide a ball game-related training system to fire a ball toward the player on the play field so that the player may smoothly practice the receive operation of the fired ball.
  • the play field or court may refer to a soccer field, a basketball court, a volleyball court, and a foot volleyball court.
  • a ball game-related training system comprising: a play field defined by a half line, both opposing end lines, and both opposing side lines, wherein the play field is configured to be downwardly inclined from the half line to each end line, wherein the play field has a ball guide groove line defined therein along each end line, wherein the ball guide groove line is configured to be downwardly inclined from one end to the other end thereof, a ball shooting apparatus configured to shoot a ball toward a target position on the play field, wherein the ball shooting apparatus is disposed on a corner of the paly field, wherein the ball shooting apparatus has a ball container receiving a ball from above; a ball supply apparatus disposed at a higher position of a net disposed on the half line of the play field, wherein the ball supply apparatus has an upper ball receiving opening to receive a ball from above, and the ball supply apparatus has a lower rotatable ball discharge tube, and the ball supply apparatus is configured to fall down the received ball on the play field via the ball discharge tube
  • a ball game-related training system comprising: a play field defined by a half line, both opposing end lines, and both opposing side lines, wherein the play field is configured to be downwardly inclined from the half line to each end line, wherein the play field has a ball guide groove line defined therein along each end line, wherein the ball guide groove line is configured to be downwardly inclined from one end to the other end thereof; a ball shooting apparatus configured to shoot a ball toward a target position on the play field, wherein the ball shooting apparatus is disposed on a corner of the paly field, wherein the ball shooting apparatus has a ball container receiving a ball from above; a ball collection apparatus disposed on the other end of the ball guide groove line, wherein the ball collection apparatus includes a vertical hollow ball guide elongate cylinder, and the ball is collected from the groove line and moves upwardly in and along the vertical hollow ball guide elongate cylinder using a collection motor, and the ball collection apparatus has an upper rotatable ball discharge tube,
