Description

The present invention relates to a practice tool for learning and improving a baseball throwing form.

Until now, there was no practice tool to correct or correct such a throwing form. The practice tool of the present invention makes it easy to check the position of the elbow that is important for pitching, so that the correct elbow position can be obtained even if the player himself (even a child) feels it and the instructor is not there. The main feature is that you can understand where it is right and correct it yourself. Patent Document 1 is a pitching practice tool effective for strengthening muscular strength, but is not necessarily suitable for correcting and correcting the pitching form.

In baseball pitcher's pitching practice, it is often pointed out that the elbow is lowered, but the player who is throwing himself understands what kind of state it is going down and what it is like going up I'm not there. The present invention provides a training tool that can immediately understand and understand the difference (whether the elbow is lowered) even if the player is a child even if the player does not know such a state.

The present invention has a baseball ball and a guide member fixed to the ball, and the guide member has a length in contact with the back of the head at the top position of the pitching operation that grips the ball. A pitching form correction practice tool may be provided, and a display unit may be provided on the ball to indicate the position of a finger to be gripped.

The present invention grasps the ball, for example, straight (ball type) and places the arm at the top position of the pitching operation, and confirms that the elbow is on the correct elbow position and the shoulder extension line at this time. By pressing the tip of the member against the back of the head and moving to the pitching movement, the player understands where the correct elbow position is, and learns by experiencing and experiencing the pitch form to correct and correct it. Things can be done easily.

Place your finger correctly on the ball's printed display and check if the elbow is in the correct position at the top of the place where the ball is thrown and base the state where the tip of the guide member is pressed against the back of the head View from above.

The throwing form correction training tool of the present invention will be described with reference to FIGS.
In the throwing form correction practice tool shown in FIG. 1, a guide member 2 is fixed to a baseball ball 1. The ball 1 and the guide member 2 may be fixed separately, or may be formed by integrally molding with resin. Reference numeral 10 denotes a display unit indicating the position of a finger gripped on the ball. The length L of the guide member 2 is preferably about 50 cm. In the pitching motion shown in FIG. 3, the length L is determined by grasping the ball 1 with the index finger and middle finger of the hand 3 along the ball display unit 10 and the top position (the elbow 4 is on the shoulder 5) in the pitching motion. The guide member 2 can be pressed against the occipital region 6. Usually, this length L should be about 50 cm. In baseball pitching, wearing this top position is essential for pitchers in particular because mechanical and elbow and shoulder failures are unlikely to occur. Thus, the player can confirm the correct position of the elbow 4, that is, the top position, by experiencing the state in which the player presses the guide member 2 against the back of the head 6 during the pitching operation. As shown in FIG. 2, the guide member 2 should be positioned below the angle theta instead of perpendicular to the finger position, as shown in FIG. 2, so that it can be used according to the size of the body. Thus, it can be surely pressed against the back of the head.

  As shown in FIGS. 3, 4, and 5, when the pitcher presses the guide member 3 against the back of the head 6 until just before the release point, the pitching operation is completed with the position of the elbow from the top position being correct. Can be realized.
