【Example】

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIGS. 1 to 7 show a gate ball training device according to a first embodiment of the present invention. FIG. 1 shows the gate ball training device of the present embodiment mounted on a normal stick head carried by a right-handed trainer. FIG. 2 is a front view in a state of being mounted and struck forward (in the x direction), FIG. 2 is a view along arrow AA in FIG. 1, FIG. 3 is a plan view, and FIG. FIG. 5 is a sectional view taken along line CC of FIG. 1, and FIG. 6 is a perspective view of the first embodiment. The gate ball training device of this embodiment has a rail 7 composed of two rail members, and mounting means 55 at the rear of the rail 7 for mounting the rail 7 to a normal gate ball stick 50. And so on. The rail 7 is composed of two rail components 7a, 7a arranged substantially in parallel from the rear to the front (x direction), and the rail 7 rises from near the bottom of the front end of the head 4 forward. It is curved in the shape of an arc. The radius of the curved line of the rail 7 is formed to be appropriately larger than the radius of the arc-shaped orbit drawn by the bottom of the head 4 when each of the trainees performs a striking operation. The two rail members 7a, 7a are arranged at an interval smaller than the diameter of the ball 1 by an appropriate amount, and the cross section of the rail 7 is such that when the ball 1 is placed on the rail 7, as shown in FIG. In addition, the bottom of the ball 1 is configured to protrude downward from the bottom of the rail 7 by a dimension a. The two rail members 7a, 7a have a flat plate portion 18 integrally formed at the rear portion (-x side) as shown in the drawing, and a stopper seat 19 is provided on the upper surface of the rear end portion of the flat plate portion 18.
Is provided. Ribs 20 are provided upright on both sides of the flat plate portion 18 in the width direction (z direction). A loose hole 21 is formed in each of the two ribs 20, and these loose holes 21 are located on a line in the z direction. The two loose holes 21 are located forward (x side) of the stopper seat 19. The distal end of the rail 7 is formed as a distal end portion 13 integrally connecting the two rail constituting members 7a, 7a. Reference numeral 8 denotes a band for attaching the gate ball training device of the present embodiment to the head 4 of a normal stick. On both sides of the band 8 in the z direction, seats each having a blind hole 22 into which female threads are threaded as shown in the figure are provided. Provided. The two female screws 22 are aligned with the z direction. The lower portion of the band 8 is extended rearwardly (-x side) appropriately long, and a seat 23 is provided on the lower surface of this extended portion. The rail 7 and the band 8 are attached by screwing two stepped screws 24 from both sides through the loose holes 21 into the female screw holes 22 of the band. The stopper seat 19 and the seat 23 are configured so as to be in contact with each other when the tangent of the rail curve near the striking surface is substantially parallel to the ground 2 in a state where the trainer is holding the trainer. Reference numeral 9 denotes a mounting screw for tightening and fixing the band 8 to the head 4, and reference numeral 10 denotes a wing nut that can be screwed into the screw. The rail body 7 attached as described above can rotate around the band 8 in the counterclockwise direction around the stepped screw 24 as shown in FIG. It is prohibited by the contact between the stopper seat 19 and the seat 23. The gate ball training device according to the first embodiment of the present invention is configured as described above. To attach the embodiment to a normal stick, the band 8 is fitted into the front portion of the head 4 and the mounting screw 9 and the butterfly are attached. The hand 8 is fixed to the head 4 by a nut 10. The first embodiment of the present invention can be mounted on the head of a normal stick as described above, and in this state, the trainee can swing the stick 50 and the rail 7 integrally. Hereinafter, a method of performing a hitting practice using the first embodiment will be described as an operation description. First, the striking posture is taken as in the case of a normal gate ball, and the center of the head 4 and the center of the ball 1 are aligned as shown in FIGS. 1, 2 and 3 as described above. In this state, the relationship between the ball 1 and the two rail component members 7a is as shown in FIG.
Is located above the grounded ground 2 by a height b dimension. That is, the bottom of the rail 7 is held above the ground 2 with the center of mind, and the dimension of the height b is smaller than the dimension a shown in FIG. Accordingly, the ball 1 does not contact the rail 7 and remains supported on the ground 2. That is, there are gaps between the ball 1 and the rail member 7a in the Y and Z directions. Next, when the take-back is taken and the head 4 is pulled in the (-) x direction, the bottom of the head 4 moves along the concave arc-shaped trajectory S upward in the vertical plane formed on the rolling line 3. 7
And move backward. However, as described above, the radius of the curvature of the rail 7 is larger than the radius of the circular orbit S of each trainee. From this, as the takeback progresses, the bottom of the rail body 7 comes into contact with the ground 2 and thereafter is pulled backward by the head 4 while rubbing the ground 2 without contacting the ball 1. With this movement, the rail 7 rotates counterclockwise with respect to the band 8 around the stepped screw 24, and when the rotation angle becomes the angle θ2 as shown in FIG. finish. At this end point, the rail 7 comes into contact with the ground 2 at the ground contact point 2 ', and the height of the bottom of the rail 7 from the ground at the stationary ball position is b'. In other words, in this embodiment, when the bottom of the rail body 7 is lifted up by the dimension b from the ground to take back,
After the takeback, the height from the ground at the stationary ball position to the bottom of the rail 7 increases to b '. However, by forming the radius of the rail 7 curve to be the same as the largest radius of the arc-shaped orbit at the bottom of the head 4 that each trainee may have, or the radius slightly larger than that, The dimensions b to b '
In practice, the increase amount can be limited to a very small size, and even if the trainees take back with a unique orbital radius, the trouble that the rail 7 lifts the ball 1 does not occur. Next, the ball is hit by swinging the head 4 forward (in the x direction). In this case, the track member 7 contacts the ball 1 while rubbing the ground 2 while following the reverse process of the takeback. Instead, the head 4 moves forward by being pushed by the head, and rotates clockwise with respect to the head 4 by θ2 to return to the original state of FIG. 1, and at the same time, the head 4 hits the ball 1. At the same time as the impact, the stopper seat 19
And the seat 23 are in contact with each other, so that the rail 7 is prevented from further rotating in the clockwise direction with respect to the head 4. The ball 1 hit by the hitting surface 5 of the head 4 rolls in the x direction on the ground 2 without contacting the rail 7 by a small distance.
The rolling speed of the ball 1 is usually higher than the x-direction component of the speed of the rail 7 which is swung in the x-direction. However, the rail 7 which is prohibited from rotating clockwise with respect to the head continues to ascend in the Y direction along the arc-shaped orbit after being hit. That is, the rail 7 continues to ascend the rail portion located in front of the ball while chasing the ball 1 at a lower speed than the ball. The ball 1 is eventually brought into contact with the rail 7 and rides on the rail 7 so as to be scooped up.
Then, the ball 1 starts rolling on the rail 7 while straddling the two rail constituting members 7a. The ball 1 that has begun rolling on the rail 7 stalls as the head 4 swings out in the X direction. This stall is X
This is due to an increase in the inclination of the rail 7 caused by the swing of the head 4 in the direction. In other words, the ball 1 rolling on the rail 7 rolls toward the tip of the rail 7 at a speed higher than that of the rail 7 in the initial stage of riding, but the rail 7 draws an arc and moves upward in the X direction. Ball 1
Gradually climbs a steeply upward slope and the ball 1
This is because the braking force acts on. Such effective braking for a relatively long time occurs because the rail 7 moves in the same direction as the ball 1. The braking performed while increasing the inclination of the rail body 7 does not hinder the naive striking operation, and acts extremely smoothly. The ball 1 stalled on the rail 7 has a head 4 on the rail.
Rolling down until. In this case, if the head 4 is put on the ground and the ball that returns is waiting, the ball 1 rolls over the rail to a certain point and falls down, and from the middle, puts the bottom of the ball on the ground and leaves the rail, It returns to the front of the head 4 by inertia. The configuration and operation of the gate ball training device according to the first embodiment of the present invention are as described above. The ball hit on the ground 2 is braked on the rail and returned to the ground in front of the head. This eliminates the need for troublesome collecting and positioning of the ball by the head for positioning and the like, so that the trainee can easily practice hitting repeatedly in a narrow place while standing at the same position.
It is preferable to carry out such exercises so that the center line of the orbital curve is in the vertical plane set up on the rolling line 3, whereby the head is taken back along the rolling line and swung out. You can learn the basics of In particular, according to the present embodiment, the misalignment of the head striking surface 5 that occurs during the take-back and swing-out operations appears as a swing at the tip of the rail, so that it can be visually recognized in real time under the eyes. According to the present embodiment, when the ball is hit too hard, the ball 1 runs up to the takeback end point portion 12, but the rail tip 13 functions as a stopper to prevent the ball 1 from jumping out of the rail 7. The gateball training device of the present invention is most easy to use when the arcuate curve of the rail 7 is in the vertical plane on the rolling line 3 while the trainee is holding the trainer. In view of the above, it is desirable to be able to change θ1 in FIG. In this embodiment, θ1 can be adjusted only by loosening the wing nut 10 and rotating the band 8 together with the rail around the cylindrical head 4. After the adjustment, tighten the wing nut 10 firmly. In the first embodiment, the rail 7 is rotatable forward with the screw 24 as an axis, but the present embodiment is characterized in that the band 8 attached to the head 4
Therefore, the rail 7 can be tilted upward (in the x direction) so that it can be easily implemented by various structures other than the first embodiment. FIGS. 8 (a) and 8 (b) are partial front views showing a modification of the first embodiment. In this modification, the two solid rail members 7b, 7b are both divided lines 25 near the head 4. As shown in the figure, the upper part of the divided rail member 7b is adhered and bonded with a leather material 26 having appropriate flexibility. The dividing line 25 has substantially no gap. Even in the configuration as in the present modification, the rail 7 in front of the dividing line 25 can be tiltably connected to the rail and band 8a behind the dividing line 25 so that the front can move up and down. Therefore, the configuration as in the present modified example also has the same operation and effect as the first embodiment. FIG. 8 (b) is a front view showing a state in which the rail body 7 is tilted in the upward direction and the leather material 26 is bent. FIG. 9 is a front view similar to the above, showing a gate ball training tool according to a second embodiment of the present invention. The difference between the present embodiment and the first embodiment is that the first embodiment forbids the clockwise rotation of the rail 7 after hitting the ball 1 by the contact between the stopper seat 19 and the seat 23, In this embodiment, the seat 23 is not provided on the lower surface of the band 8b, and the stopper seat 19 is configured to abut the lower surface of the head 4 of the normal stick 50 so as to prohibit the clockwise rotation of the rail 7 after hitting the ball. All other parts are the same as in the first embodiment. Even in the case of the structure of the present embodiment, when a normal stick head 4 is attached to the band 8b to perform a hitting practice, the stopper seat 19 abuts on the lower surface of the head 4 similarly to the hitting of the ball 1, and Since the clockwise rotation of the rail 7 is prohibited, the same operation and effect as those of the first embodiment can be obtained.
