Description

[Detailed description of the invention] This Komei Fi can be done indoors with Col 7 [# pottery.

When practicing golf in a narrow venue such as indoors,
I want to know the exact direction and flight distance of a golf ball hit with Jin, and there are various golf practice tools devised to accurately calculate this. It has been changed to "H". However, these conventional methods are generally
;r(j There is a problem with the detection method of the direction and speed of the ball, so 1
The difference is huge, and I still haven't had a satisfying golf experience. For example, in a conventional golf training machine, optical sensors and magnetic sensors are used to detect the direction and speed of the club head on the left and right sides when it hits a golf ball that has hit the 0-ball point to detect the distance. There is a method that uses the detection method to perform guessing. However, with this method, when there is just contact with the face of the club head or the golf ball, Vi? iM? 1l
The flight direction and distance of the golf ball being played are relatively 1.
As you can see, if you don't just meet, you will end up with a pretty big 1st place, and if you hit the MM edge, the direction of the fly ball or the stone carving will be @ Zheng even if you hit the ball in the air, and the golf practice K will actually be a minus point. Ta.

The present invention was made in view of this problem, and it calculates the initial speed and direction of the golf ball when it is actually hit with a club head to prevent it from flying far. To provide a golf practice device that detects a fly ball, estimates and calculates it, and beats it.

The present invention detects the direction of the golf ball flying out from the ladle point by detecting the direction in which a string attached to the golf ball extends, and because it detects this direction, it can be used in a wide range of fields such as angle detection units. It is characterized by the use of a joystick. In addition, the flying ball speed of the golf ball I flying from the rlf* point of the present invention is detected by measuring the time 1 when the golf ball leaves the r1 ball point and the string ends in a straight line. It is characterized by the use of a sensor that detects the presence or absence of a golf ball at the hitting point and a sensor that detects the point in time when the string reaches its end due to the time detection method. In this way, by directly detecting the speed and direction of the golf ball itself when it hits the ball, even if the club head does not hit the ball just right, the flight direction of the golf ball and the direction of the golf ball can be accurately determined.
Measurement calculation is performed.

The +lt composition of this example is shown below in detail along with the example of j. A long set of balls (1) with one end of K (b) fixed, (4
) is the joystick installed on the mat (21 -&i>, (51F'i) is a robe equipped with a built-in circuit board.) At the tip of the bat string (8) from the golf ball I and 111. A cylindrical sleeve (6) is fixed, and this sleeve (6)
) is removably fitted coaxially into the arm (7) of the joystick (4). Further, near the tip K of the string (3), one end of an elastic strip i81 such as a spring is fixed, and the other end of this elastic strip (8) is fixed to a part of the mat (21).

The golf ball (1) is placed in the position of the golf ball (2) and is placed in the upper position (outside position) and hangs to the left of the drawing. A golf ball sensor (9) at the ball-hitting position is installed, and the arm 171K of the joystick (41) is attached with a co-sensor i0 for detecting the presence or absence of three 1+61.The first sensor t9

- The 1st oscillation angle (inclination angle and This is an angle detection unit that detects the direction (direction) using electrical output, and this is made up of a single moving permanent magnet with axial magnetization inside the spherical member cap, and two magnetoelectric magnets built into the support member seat. A child, for example, a magnetoresistive cable uqOη
It consists of The permanent magnet 45051 is arranged in the same manner as the arm (7), and each magnetoresistance effect element Oη is a forest-like member t.
Each Kankan 1fu is placed on two orthogonal planes in the construction direction and the Y direction that are equidistant from 12.1 and are 1-spaced from each other. Each of these resistors exerts a magnetoresistance effect on the insulating substrate as shown in FIG. 2, for example! &
Two orthogonal MR stripes consisting of thin magnetic pieces (09 Ilne he theory) were created, and a bias voltage vo was marked at both ends of each MR stripe σG + 7U 2AI

However, k is the constitution of the material, and θ forms the angle pi of jQ with the MR stripe 44! - This is the incident angle of the magnetic flux H as seen from the direction P. Therefore, one magnetoresistive cable IlQη is arranged in two directions, X and Y, and the magnetic field of the permanent magnet U+, which is integrated with the arm (7), is applied to it to generate the respective outputs. V
When calculating Y, the swing angle of A, - (7) (I#4 oblique angle and direction) is decomposed into 1η angle components and detected. For example, if the inclination angle of the arm (7) is ψ and the rotation angle is ω, the output of each #1 magnetoresistive element Oη will explain the rotation and distance detection friction from the relationship of equation 1. .

Place the 11t cloak (2) on the upper hitting position and attach the mla+ sleeve +61 to the tip of the arm (7) of the joystick (4).

The time signal is inputted to the arithmetic circuit (Ill) as a time signal via the conversion circuit (c).In addition, the sensor (9) in this @2 figure detects the golf ball (1). It is only in the cylindrical cord when the body is 2-nd (lα
The sleeve f81 is designed so that it is in the open state ThK6 only when it is inserted into the arm (7) to the normal position.

With the string in the shape of the clam shown in Figure 2, which has been hit seven times in the above manner, the golf ball il+ is strongly hit with a golf flag head in the direction of the arrow in the body diagram. Then, the golf ball Ill is hidden from the ball hitting position on Yt (2), and the instant clam/sensor (9)

For example, from the initial velocity V of the golf ball (11) and the flight angle (the arm (7 tilt angle ψ) of the above-mentioned white stick (4)), the initial velocity vyo and If the initial velocity skin component vxo in the horizontal direction with the ground is taken into account, and the earth's gravitational force is g and 2V @V, the flight distance S is determined by 8-part and-' shell-.

Also, the direction of the ball (direction) is determined by the rotation angle θ of the arm (7) of the Nil stick (41).

Also, when the golf ball il+ flies to the length of the pair (3), the sleeve (6) comes out from the arm (7), and after that the elastic strip (8) stretches a little and pulls the string (3). This is to prevent the golf ball from flying too far. When the seven exercises are completed, the sleeve (6) is placed over the arm 171 again, the golf ball is returned to the t]# position, and the first round is performed.

Note that the zero-launch boat is not limited to the above-mentioned embodiment, and various modifications can be made to the river boat. For example, it is possible to prevent the sleeve i81 from falling off the arm +71, thereby saving the effort of putting the sleeve (6) over the arm 17)K every seven exercises, or

It is also possible to detect a missed Kronk Pa I response with a kakunter, etc.@As explained above, misfire-1 is actually a method of detecting the fly ball speed and direction of a golf ball. Since the direction of the ball and the flight distance t are calculated and displayed, accuracy is increased and a highly reliable golf practice device can be provided. In addition, since the direction of the ball is detected instantly, it is possible to detect a wide range of directions.
