Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball hitting training machine, and more particularly to a ball hitting training machine such as a gate ball or a golf ball.

[0002]

2. Description of the Related Art Conventional ball hitting practice machines detect the head speed of a golf club and the state of swing of the golf club as described in, for example, Japanese Patent Application Laid-Open No. 57-31881, and the ball is actually hit. The flight distance and direction of the ball are calculated assuming that the ball has hit. FIG. 6 shows an example of a conventional putter training machine. The detector 23 detects the detected member 22 attached to the tip of the striking surface 21 of the putter 20, and the detector 23 detects the detected member 22 even if the actual ball 24 is hit or there is no ball. The moving distance of the ball 24 is calculated based on the moving speed of the striking surface of the putter 20, and the distance is displayed on the display unit 25.

Since the above-mentioned training machine is intended for easy practice at home or the like, it has not been possible to confirm the hit state by using an actual ball.

[0004]

In such a conventional practice machine, since the result of the ball actually hitting the head or the like of the club is not detected, even if the ball does not hit the optimum position of the club, it cannot be detected. In order to display the result as if it was just met, there were many cases where the swing condition with the practice plane was far from the actual striking state, and it was not a true practice plane.

The present invention solves the above problems, and an object of the present invention is to provide a ball hitting practice machine for detecting an actual hit result.

[0006]

In order to achieve the above-mentioned object, the present invention comprises a detector for detecting the momentum of a ball, a ball return mechanism for returning the ball in the hit direction,
A distance setting unit that sets a distance from the hitting position of the ball, a calculation unit that calculates the movement amount of the ball based on information from the detection unit and information from the distance setting unit, and the calculation unit. And a display unit for displaying the calculation result of.

Further, the ball returning mechanism portion for returning the ball in the hit direction and the damper mechanism for the ball returning mechanism portion are provided.

[0008]

According to the present invention, since the momentum of the ball actually hit is measured by the above-mentioned structure, it is possible to practice while confirming the shot feeling, and it is also possible to practice in a short distance which requires a long distance.

Further, since the hit ball has a mechanism for automatically returning to the hitting direction, the practitioner does not have to go to pick up the ball.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. Specifically, this is an external view of the gateball training machine 1.

FIG. 2 is a sectional view of the gateball practice machine 1. A detection piece 3 for detecting the momentum of the gate ball 2, a spring 4 for urging the detection piece 3 in the direction of the gate ball 2, a rotary plate 5 integrally attached to the detection piece 3, and a magnetic wheel attached to the rotary plate 5. 6, a magnetic detection element 7 (these are detection units), a distance setting switch 8 (distance setting unit) for setting the distance from the hit position of the gate ball, a display unit 9, a calculation unit 10, a substrate 11 to which these are attached, and a gate ball 2. It is a slope 12 (ball returning mechanism) for returning in the direction of being hit, a battery 13 for driving an electric circuit, and a handle 14 in the shape of a gate. Figure 3
Shows a state in which the gateball 2 is actually hit with the stick 15. At this time, when the distance between the gateball 2 and the gateball practice machine 1 is 16, the distance 16 is set by the distance setting switch 8. The distance setting switch 8 can set an arbitrary distance according to the distance 16. The gate ball 2 rolls in the direction of the arrow 17 and enters the inside of the gate ball practice machine 1, hits the detection piece 3 and pushes up the detection piece 3 in the direction of the arrow 2a. The detection piece 3 rotates about the movable center 3a and moves in the direction of the arrow 3b. Detection piece 3
Is urged by the spring 4, but rotates in the direction of the arrow 3b in proportion to the momentum of the gate ball 2 and moves to a position balanced with the kinetic energy of the gate ball 2.
This state is shown in FIG. The rotation angle θ17 displaces the rotating plate 5 which rotates together with the rotation angle θ17 by the same angle θ. As a result, the magnet wheel 6 is displaced by the same angle θ. The magnet wheel 6 has its magnetic poles polarized at a minute angle (not shown in particular), and when the magnetic detection element 7 detects the number of polarizations corresponding to the changed angle, it is sent to the arithmetic unit 10 as a pulse. At this time, since the distance 16 is set by the distance setting switch 8, the calculation unit 10 converts this value and displays the distance corresponding to the momentum of the gate ball 2 on the display unit 9. That is, if the distance between the hitting position of the gate ball 2 and the gate ball practice machine 1 is 2 m, it is 2 m.
When the gateball 2 is hit with a strength that exceeds the limit, it is detected how much more the gateball 2 will roll from the position of the gateball practice machine 1, which is 3.3 m.
In that case, 5.3 m is displayed on the display unit 9.
In FIG. 2, a damper 3a is attached to the detection piece 3 via a mounting hole 3b by a screw 3c and a damper spring 3d (these are damper mechanism portions), and is urged by the damper spring 3d. The gate ball 2 is pushed back along the slope 12 by the force of the displaced spring 4 when the transmission of the kinetic energy of the gate ball 2 is completed by pushing up the detection piece 3. FIG. 5 shows the state. The detection piece 3 is pushed back by the spring 4 and hits the stopper 12a to stop. At this time, the damper 3a is stopped by the stopper 12a.
By the impact of hitting the arrow 18 against the damper spring 3d
Move in the direction of. As a result, the shock is absorbed, and the detection piece 3 is again hit by the shock hitting the stopper 12a, and again the arrow 3f
It will not move in the direction of (Fig. 2). Since the movement of the detection piece 3 is directly connected to the movement of the rotating plate 5 and the magnet wheel 6 attached to it, the magnet wheel 6 does not move by this, so the magnetic detection element 7 pulses as an extra signal. Since it does not count, the detection operation is performed extremely accurately. 1 in FIG.
Reference numeral 9 is a mode selection switch for selecting the type and state of the ground surface where the game of gateball is performed. That is, how the ball 2 rolls when the gate ball 2 is hit by the stick 15 with a certain force greatly changes depending on the type and state of the ground surface. For example, it is possible that the ground will roll only 10m on a rough ground, but the ground will roll only 7m on a rough ground, or only 5m when the ground is wet after rain. When practicing batting, the practitioner has the mode selection switch 19
The kind and condition of the ground to be practiced are set in advance and practiced. The mode selection switch 19 functions to change the display distance according to the mode when the arithmetic unit 10 converts the distance of the signal sent from the magnetic detection element 7.

In the above-described embodiment, for example, the detection portion is detected using magnetism, but this is not limited to magnetism, and it can be implemented by using light or a switch. A damper mechanism and the like can be implemented with various structures. Further, the display unit may not only display the distance but also inform the distance by voice or the like. Further, although the present embodiment shows a practice machine for a gate ball, a golf ball can be practiced with a completely similar structure as a putter hitting practice machine.

[0014]

According to the ball striking practice machine configured as described above, the actual momentum of the ball striking in the gate ball striking practice and the golf putting striking practice is detected, and moreover, the direction of striking is detected. Because the ball is automatically returned to you, you do not have to go to pick up the ball one by one, and you can easily practice long distances in a short distance indoors. Further, by providing a damper mechanism in the detection portion, it is possible to detect the distance with high accuracy even when the ball is impacted. Furthermore, by providing a mode selection switch that allows you to select the type and state of the ground plane, you can practice under various conditions, so you can simplify and greatly improve the effect of practice.

Since it is difficult for an elderly person to practice accurately, especially with regard to a gateball or the like, the present practice machine enables a great improvement in the technique in a short period of time.
