Abstract
A billiard ball aiming training supply comprises a body. A notch is formed in one side, comprising a plane portion and a recessed surface portion, of the body. The plane portion is perpendicular to a plane providing the body bottom, intersected with the body bottom in lower edges and intersected with the upper surface in upper edges. The upper edges are parallel to the lower edges. Distances between the upper edges and the lower edges are equal to semidiameter of a billiard ball. On the side providing the notch, the plane portion is intersected with the recessed surface portion in two longitudinal edges. Length of the longitudinal edges is equal to the semidiameter of the billiard ball. Distance between the longitudinal edges is equal to diameter of the billiard ball, and in this way, height of an opening of the notch is equal to the semidiameter of the billiard ball and width of the opening is equal to the diameter of the billiard ball.
Description
Technical field
The present invention relates to a kind of billiard training articles for use, particularly a kind of billiard ball are aiminged drill articles for use.
Background technology
When billiard ball are aiminged drill, trainer, because custom is different, can determine goal point in a different manner, and what have looks for goal point at the contour horizontal plane that is suspended in desktop of the same centre of sphere, the definite goal point on the table having, so also will grasp corresponding two straight lines in order to reach training effect.These two straight lines are respectively through the centre of sphere, to point to the straight line of sack, another is through object ball contact point (hereinafter referred to as " drop point ") on the table, and point to the straight line of sack, these two straight lines are parallel to each other, above two kinds of method effects are the same, the so-called point of scoring is on same vertical line, but there is defect separately, under battle conditions, if can be by two goal points, grasp simultaneously, namely grasp the line segment perpendicular to desktop at that goal point place, effect will be more stable, there is at present human hair to understand some trainers, by thin bar, some important lines are pointed out, but because the thickness of thin bar can not be ignored, affected the precision of training.
Summary of the invention
The invention provides a kind of training articles for use, can help trainer grasp respectively by the centre of sphere and drop point simultaneously and point to two straight lines of sack, and grasp the line segment perpendicular to desktop at the some place of scoring.
In order to realize above-mentioned technical purpose, the present invention takes following technical scheme:
It comprises main body, one side of main body has breach, the side at described breach place comprises planar section and concave part, planar section is perpendicular to the plane at bottom part body place, planar section intersects at lower edgeline with the bottom of main body, with upper surface, intersect at upper crest line, described lower edgeline and upper crest line are parallel to each other, and described lower edgeline and upper crest line spacing equal the radius of billiard ball.
Described breach place lateral plane part and concave part intersect at perpendicular crest line, the length of described perpendicular crest line equals billiard ball radius, article two, the spacing of perpendicular crest line equals the diameter of billiard ball, that is to say that the height at gap opened place equals the radius of billiard ball, and opening part width equals the diameter of billiard ball.
The length of described lower edgeline and upper crest line is more than or equal to the radius of billiard ball, planar section in side, breach place, has vertical mark, and described vertical mark is parallel to perpendicular crest line, described vertical mark is perpendicular to lower edgeline and upper crest line, and the distance of described vertical mark and perpendicular crest line equals the radius of billiard ball.
Between described vertical mark and perpendicular crest line, by oblique mark, connect, described oblique mark is the equal angle at 45 ° of same lower edgeline, upper crest line, perpendicular crest line, vertical mark respectively.
Described breach just in time holds 1/4 of billiard ball, and in billiard ball are stuck in breach, and while touching on breach concave surface certain point, the straight line at upper crest line place is just in time through the centre of sphere of billiard ball.
Beneficial effect 1. of the present invention can help trainer to grasp to be suspended in the goal point of desktop simultaneously, and the point of the goal on desktop, thereby overcomes the error in judgement causing due to reasons such as faults.
2. can help trainer grasp by the centre of sphere simultaneously and point to the straight line of sack and pass through the straight line that mother bulb drop point points to sack.
3. because the present invention has adopted solid block material, carry out the prompting of lines with the thin silk fabric line at edge, lines are more directly meticulousr, and effect is more accurate.

Fig. 2 is the structural representation of the embodiment of the present invention 1.
Fig. 3 is the structural representation of the embodiment of the present invention 2.
Fig. 4 is that the embodiment of the present invention 2 surrounds an object ball jointly by two main bodys (1), forms the schematic perspective view of a complete circle.
Fig. 5 is that the embodiment of the present invention 2 surrounds an object ball jointly by two main bodys (1), forms the floor map of a complete circle.
Fig. 6 is the floor map of the embodiment of the present invention 3.
Fig. 7 is the schematic perspective view of the embodiment of the present invention 3.
In embodiment embodiment 1 the present embodiment, main body is (1) highly for R(R is billiard ball radius), cross section is semicircular ring, outer radius is 2R, inside radius is R, that is to say breach (2) the cross section of concave surface be semicircle camber line, the length of lower edgeline (3) and upper crest line (4) equals the radius R of billiard ball just, vertical line mark is (6) just at the (2) edge of side, place of breach, so vertical mark (6) is also a crest line just.Training step 1. selected target sacks, are placed on specified point position by object ball.By main body of the present invention (1) around and be close to object ball, make object ball be fixed on breach (2) in, and by crest line (3) with the crest line sack that (4) aims at the mark.(4) and lower edgeline (3) alignment pocket 3. observe and remember following how much rules: (6) vertical mark is goal point,, (7) oblique mark points to summit and the correct point of impingement of two balls of ball to upper crest line.4. (1) main body one is opened gently, do not driven object ball.Utilize the memory of previous step and the rule of grasping, determine striking point on the ball batting.Embodiment 2 in this example, main body (1) is highly for R(R is billiard ball radius), cross section is semicircular ring, outer radius is that 2R inside radius is R, as different from Example 1, on main body (1) upper surface semicircular ring axis, make axis mark, on lateral surface arc surface, also with vertical line, vertically make mark, during training, two main bodys (1) surround object ball, a complete annulus of common formation, it is mutually vertical that its effect is equal to two adjacent crest lines (4), point to the centre of sphere simultaneously, and on exterior arc surface, there is vertical mark everywhere, indicate goal point.
In concrete training step reference example 1. embodiment 3 the present embodiment, main body (1) is highly R, the length of lower edgeline (3) and upper crest line (4) is greater than the radius of billiard ball, the concave surface of breach (2) consists of jointly four planes perpendicular to bottom, the cross section that is to say the concave surface of breach (2) consists of four straightways, the semicircle tangential that these four straightways are R with radius.
Concrete training step reference example 1.
