Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pitching training device. More specifically, the present invention relates to an improvement of a device for practicing the pitching of a baseball pitcher in terms of actual operability.

[0002]

2. Description of the Related Art Conventionally, as a pitching training device, for example,
Connected to the pitch receiving net stretched toward the pitcher, a hit plate formed in an area equivalent to the strike zone and fixed to the pitch receiving net, a pressure sensor attached to the hit plate, and a pressure sensor A display unit is known.

In this conventional pitching practice apparatus, when a ball thrown by a pitcher collides with the hitting plate, a pressure sensor detects the impact of the ball collision and "strikes" on the display.
When the ball thrown by the pitcher does not collide with the hitting plate, the pressure sensor does not detect the impact of the ball collision and displays “ball” on the display unit.

[0004]

In the above-mentioned conventional pitching practice device, the strike zone is fixed although the height of the strike zone varies depending on the height of the batter. Therefore, the "strike" and the "ball" that are not related to the assumed batter are uniformly displayed. In addition, "strike" and "ball" depending on the difference between right and left hits of the batter and the strength and weakness of the batter.
Is also affected substantially, and the “strike” and “ball” displayed on the judgment screen and the hitting possibility of the batter do not necessarily match.

Therefore, a simple "strike" by the fixed strike zone of the above-mentioned conventional pitching practice device,
The "ball" judgment display has a problem that it is not possible to practice pitching practice.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a pitching training device capable of practical pitching training.

[0007]

In order to solve the above-mentioned problems, the pitching training apparatus according to the present invention employs the following means.

That is, in claim 1, at least a sensor for detecting the passing position of the pitched ball with respect to the strike zone as "strike" or "ball", and a "strike" or "ball" based on the detection signal of the sensor. The controller includes a controller that calculates information about the batter or the like that is determined and assumed, an input unit that inputs information about the batter or the like assumed by the controller, and a display unit that displays the calculation result of the controller.

According to a second aspect of the present invention, in the pitching practice device according to the first aspect, the sensors are arranged at a constant interval in the ball passing direction.

A second aspect of the present invention is the pitching practice device according to the first aspect, further comprising a strike zone display mechanism for displaying a strike zone visually recognizable by the pitcher.

[0011]

According to the above-mentioned means, by operating the input unit, it is possible to input the information such as the estimated height of the batter, right hit, left hit, etc. to the controller. The controller to which the batter information is input sets an appropriate strike zone corresponding to the assumed batter for the detection signal of the sensor. The "strike" and "ball" are arithmetically determined according to the set strike zone, and the determination result is displayed on the display unit. The pitcher knows the effectiveness of the previous pitch for the batter based on the contents displayed on the display unit, and with reference to this, the pitcher thinks and helps the next pitch. In addition to other information necessary for determining "strike" and "ball", the hit probability of the batter is calculated and displayed on the display unit. When the type and speed of the ball thrown by the sensor are detected, the amount of information of the controller that calculates the hitting possibility of the batter increases.

According to the embodiment, the type and speed of the pitched ball are detected by the sensors spaced apart in the ball passing direction. The display of the strike zone is the target of the pitch.
