Abstract

The invention relates to billiard training equipment, in particular to a training billiard table which comprises table top welt pocket openings. The training billiard table is characterized in that positions in front of holes of four corner pockets are respectively marked, the distance L between the center of each mark and each of two adjacent welt is (R2-(H-R)2) 1/2, the R refers to the radius of a billiard ball, the H refers to the height of each welt from a table top, and the L refers to the distance between the contact point of the billiard ball next to the corresponding welt and the table top and the horizontal direction of the welt. The marks near the pocket openings in the table top can be called 'universal target points', and target balls can certainly enter the pockets and cannot be hung by welt corners of the pocket openings as long as the target balls can be accurately hit to the points no matter which position the target balls are placed outside the pocket openings on the table top.

Description

A kind of billiard table of training use

Technical field:

The present invention relates to a kind of billiard training equipment, particularly relate to a kind of billiard table of training use.

Background technology:

In billiard movement, when object ball just to the situation of sack under, namely near the axis of sack time, even distance is slightly far away, score also relatively easy, and when departing from the contrary sack axis, even relatively closer from sack, score also more difficult, once grasp badly, just easily tangled by the turning of Ku Bian and sack.

Summary of the invention:

The invention provides a kind of billiard table, allow trainer know a specific some position, no matter object ball is in sack which position around, is all same impact point position by the unification of target sack, so that player grasps.

In order to realize appeal technical purpose, the present invention takes following technical scheme: it comprises limit, table top storehouse sack, and mark is made respectively in the position that it is characterized in that being positioned at before the hole of four angle bags, and described mark center is to the distance L=(R on limit, adjacent two storehouses ²-(H-R) ²) ^1/2, R is billiard ball radius, and H is the height of limit, storehouse from desktop, and described L is exactly which billiard ball during near limit, storehouse, and the contact point of these billiard ball and desktop, to the distance of limit, storehouse horizontal direction.

Described mark intersects with dot pattern or two straight lines or more than two straight line intersects to draw.

Beneficial effect of the present invention:

The mark of desktop upper bag mouth annex can be called " omnipotent impact point:, no matter object ball that position outside desktop upper bag mouth, as long as can accurately be hit to this point, all must enter bag, can not tangled by limit, the storehouse corner of sack.

Accompanying drawing explanation:

Fig. 1 is schematic diagram of the present invention.

Fig. 2 is calculation of parameter geometrical principle schematic diagram of the present invention.

Embodiment:

Before training, near sack, draw out accurately mark, this mark is substituted to the final goal point of sack as object ball, bat, and keep the spatial relationship of this mark and target sack firmly in mind, to form good aiming custom, in order to increase third dimension, also column marker thing can be placed on to this above mark, effect is by better.

Claims

1. train a billiard table for use, it comprises table top (1) limit, storehouse (2) sack (3), it is characterized in that: mark (4) is made respectively in the position being positioned at before the hole of four angle bags.

2. a kind of billiard table of training use according to claim 1, is characterized in that: the height of setting limit, storehouse destage face is H, and the radius of billiard ball is R, and the center of mark (4) is L=(R from the distance of adjacent limit, two storehouses horizontal direction ²-(H-R) ²) ^1/2.

3. a kind of billiard table of training use according to claim 1, is characterized in that: described mark dot pattern or two straight lines intersect or more than two straight line intersects to draw.
