Description

Billiards training and correctional device using raser beam

The present invention relates to a device for practicing and correcting billiards that allows accurate billiard shots, and in particular, by making a hit with a laser beam on the water polo to perform an accurate shot, efficient billiard practice and hitting correction by various other batting methods. It relates to a billiards practice and correction device using a laser beam that can be used.

In general, even if you have a good preliminary stroke in billiards, it often goes wrong the moment you hit the shot. This is because force is applied to the shoulder, arm, or wrist movement, or accurate shot movement does not occur. In this case, since the cue cannot go out in a straight line, it is not possible to hit an accurate RBI, and eventually it cannot lead to a score. In order to overcome this, the body needs to get used to making an accurate shot when the shoulder, arm, or wrist is operated, and a device capable of practicing or correcting for this is required.

As a background technology of the present invention, as Korean Patent Registration No. 10-0919752, 'a billiard stroke practice aid' is proposed. It includes a body portion comprising a smooth surface of the body portion formed of a rectangular smooth surface; One or more horizontal target parts that are scored through the seating position of the cue-to-tip seated on the upper surface by forming the same smooth surface as the body part smooth surface at a predetermined position of the body part, or formed perpendicular to the body part smooth surface, the front surface A target unit comprising at least one of one or more vertical target units capable of checking a score through the striking position of the cue base tip being hit on; The left or right horizontal position of the cue table tip is confirmed at the front of the body part or the upper end of the vertical target part, and the front and rear horizontal movement distance of the cue table tip is confirmed on the left or right side of the body part, or at the upper end of the vertical target part A scale part to check the vertical position of the cue table tip; and one or two or more guide lines formed in the longitudinal direction of the rectangle at the center of the body portion to guide the linear movement of the cue table.

However, in the background art, the target part is printed on a billiard table, cloth, paper, etc., then the stroke shot is made and the result is immediately recognized to correct the stroke posture. It is difficult to correct posture because you are not guided directly by it, and it is difficult to learn or correct basic postures such as pushing and pulling with a billiard ball (water polo).

As another technology that is the background of the present invention, a 'portable billiard stroke practice machine' is proposed as Korean Patent Registration No. 10-1779838. This provides the advantage of being able to practice anytime and anywhere by partially dividing the cue table to make it portable, but there is no means to guide the stroke shot or achieve posture correction, so the billiard stroke can be corrected. none.
