Description

Indoor Screen Baseball Practice System and Its Implementation Method

The present invention relates to a baseball practice system and an implementation method thereof, and more particularly to an indoor screen baseball practice system and its implementation method.

Conventionally, a baseball driving range for baseball batting practice has been used.

However, most baseball practice fields have been used in a manner in which a net is installed outdoors and a user strikes a pitching ball of a pitching machine.

This is a simple baseball practice system for simple fun, far from correcting or supplementing baseball skills.

On the other hand, in the case of golf, it is possible to calibrate his / her ability while correcting his swing posture or calculating the distance through the indoor screen driving range.

In baseball practice, pitching and betting poses and motions are as important as golf, and correcting these poses or motions is essential to improve your skills. In particular, pitching pitches, rules, etc. can be said to be a very complicated and difficult item.

However, the existing baseball practice system in this respect also relies mostly on mechanical methods or for practice without analysis.

Japanese Patent Laid-Open Nos. 1996-0010035 and 2003-0063603 disclose such a conventional baseball practice system.
