Abstract

The utility model relates to an exercising appliance for hitting billiards into pockets on a pocket type billiard table. The exercising appliance uses a new and simple method which is obtained by calculation mainly based on the method of ranging aim that combines the traditional method of aiming thickness. The utility model is composed of an angle scale, an angle-measuring pointer and a ranging ruler, and can measure the impact point between a main ball and a target ball, the degrees and the aiming points of various deflected balls, and the data (in millimeter) of the measured aim distance. With the utility model, billiard fans and sportsmen can quickly and skillfully master the basic rule of hitting the billiards into the pockets, so that the aiming accuracy is increased.

Description

Billiards aiming practised unit

Originally take aim at and survey exercising machine and belong to a kind of billiard ball and bat into bag exercise of basic training Training Practicing.The key skills of pocket billiards motion is to aim true, and scores and how just can win victory.The multiple drift angle ball that cue ball and object ball form, current all is that overlapping thickness degree by two balls addresses.This method gropes to accumulate experience and need lean on than long time exercise owing to there is not definite quantitative aiming foundation, be difficult to make billiard movement fan and sportsman to grasp the aiming rule fast because of wasting time and energy.

The purpose of the utility model exercising machine is to provide a kind of pocket billiards motion training directly perceived and exercising tool, this apparatus advances a bag angle, separates relative theories such as trend and course according to object ball, the range finding method of sight of coming out with new derivation, the survey mode of taking aim at the numeral demonstration, make billiards lovers and sportsman can expertly grasp basic works and basic law that bag is gone in batting rapidly, be beneficial to improve and take aim at the survey accuracy rate.

Pocket billiards is taken aim at the structure of surveying exercising machine:

It is by angle scale, and angle measurement pointer and range finding scale are formed.In rectangular chassis (5) top 90 ° of triangle open mouths are arranged, it is the positioning port (1) of object ball, on the longitudinal axis of chassis, be that semicircle is drawn in the center of circle with (O), the semicircle radius is identical with the billiard ball radius, about delineating 0～90 ° angle scale (2), on the point of the center of circle of angle scale (O), angle measurement pointer (3) is housed, on the pointer of (O) point that by (O) point is a billiard ball diameter apart, range finding scale (4) (scale unit is millimeter) is housed.

The card longitudinal central axis line and the left and right sides of angle scale in said structure, also mark is drawn three piano wire 0-6,7-8 and 9-10.With the perpendicular horizontal direction of angle scale longitudinal central axis, mark is drawn three range finding scale alignment target line 7-9,11-12 and 8-10.The radius of angle scale is identical with the billiard ball radius of taking aim at survey.

Accompanying drawing of the present utility model has:

Fig. 1 is that pocket billiards is taken aim at the plane of surveying exercising machine.

Fig. 2, Fig. 3 and Fig. 4 take aim to survey device user mode contrast figure.

Wherein Fig. 2 is the survey situation of taking aim at of hitting 20 ° of drift angle balls.Fig. 3 is the survey situation of taking aim at of hitting 40 ° of drift angle balls.Fig. 4 is the principle schematic that bag is gone in batting.

In conjunction with the accompanying drawings using method of the present utility model is described as follows:

Use this to take aim at when surveying device, to take aim at the angle measurement pointer of survey device and 0 degree alignment on the angle scale earlier, then take aim at the angle measurement pointer of surveying device aim at the mark ball the center (O ") and sack center (13); just (13), (O "), (O) in line, will take aim at survey device chassis (5) at 3 puts well and ajusts (see figure 4).Can determine that at first it is (14) a little that bump between cue ball and object ball is gone into hitting of bag, aiming point is (O) point, and then measures drift angle angle (α) and take aim at range finding from (X).

Take aim at survey device put in place after, stir the angle measurement pointer and make needle point point to cue ball center (O ₁), in the recess of pointer afterbody, just can on angle scale, demonstrate angle (α) degree of drift angle simultaneously.Then check the numerical value of the sighting range (X) on the range finding scale again.

When the drift angle of bag is in 30 degree if bat, should check (0-6) line of central authorities and the shown numerical value of coincide point of the scale of finding range.If (7-8) of both sides or (9-10) the shown numerical value of coincide point of two piano wires and range finding scale when spending greater than 30, then will be checked in the batting drift angle, promptly be the aiming numerical value (X) millimeter of the survey of asking.

Illustrate again according to the above-mentioned survey device basic operation using method of taking aim at:

1, beats straight shot

To take aim at earlier and survey device opening (1), be stuck under the object ball, with (O) point on (0 ') point on the range finding scale and the angle scale and sack (13) point, cue ball center (O ₁) put in line, just can beat straight shot (seeing the left figure of Fig. 4).

2, train off corner-kick

To take aim at equally earlier and survey device opening (1), be stuck under the object ball, make the object ball center (O ") and angle scale center (O); alignment pocket center (13); stir angle measurement pointer (3) then; after pointing to the cue ball center, the pointer aft recess is presented at 20 degree positions on angle scale, the angle that this drift angle ball is described is 20 degree.The range finding scale is put at horizontal level, scale on the scale and piano wire (0-6) heavily are contained in 20 millimeters places again, and promptly sighting range is 20 millimeters (see figure 2)s.Promptly (O ") (15) point at 20 millimeters places left addresses and just can go into bag by the object ball center.

Play 40 degree drift angle balls and also use the quadrat method (see figure 3).The ball of other various angles just can be taken aim at the data of measuring various needs by that analogy.

3, take aim at the piano wire of surveying on the device

Take aim at and survey own centre line (0-6), left piano wire (7-8) and right piano wire (9-10) on the device.The usage of these three lines is: center line and range finding scale (4) are joined and are contained, and are used to measure the angle of 30 degree with interior various drift angles ball.Left and right piano wire cooperates with the range finding scale, is used to measure the angle greater than the various drift angles of 30 degree ball.

When for example playing the inclined to one side ball of 40 degree, angle measurement pointer aft recess refers to that when 40 spend the range finding scale then overlaps at 8 millimeters places with left side (7-8) piano wire, and 8 millimeters places address outside the object ball edge, just can be driven into the ball bag to the 40 drift angle balls of spending angles.
