Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel golf practice device that is capable of electrically processing and displaying data during the swing of a golf club. And intermittent practice is essential.

The best way to practice rationally is to use a special practice device, but in that case, it is important to check not only the state of the swing of the golf club, but also the amount of weight distribution on both feet during the swing. It is clear that if the movement of body weight could be determined, it would be extremely effective in shaping the form.

The present invention has been made in view of the above, and is a golf practice that makes it easy to learn the correct 7 ohms by detecting the amount of weight distribution applied to both feet during a swing and displaying this distribution amount. The purpose is to provide equipment.

The present invention will be described below with reference to an illustrated embodiment. 1 is a main body in which an arithmetic circuit and a display section are housed; 2 is a display section; The amount is displayed as a ratio.This figure shows an example in which the weight is equally distributed on both feet. Reference numeral 3 denotes a golf mat, and 4 a sensor installed near the position of the golf mat where the ball 5 is set, which detects the passing state of the golf club. 6 is a mat on which the practitioner stands, and two treads 7 and 8 are placed on the top surface at a predetermined distance so that they can move up and down, and a weight sensor is attached to the back of the treads. There is. FIG. 2 shows a specific example in which a coaxial optical fiber is used as the sensor 4 for detecting the passage of a club. A light source 10 such as a lamp is disposed at the end of the outer part 9, and a phototransistor 12 is disposed at the end of the inner part 11, facing each other. Therefore, when a club passes over the cut surface of the light 7 eyeper, the light reflected from the sole surface of the club is received by the phototransistor 12, passes through the amplifier 13, and then passes through the output terminal 14.
generate a pulse.

Next, the present invention will be explained in detail using the block diagram shown in FIG. detects each and converts them into electrical signals. This signal is transmitted to amplifier 1
Analog switch after being expanded in 5.16 17.18
A pulse signal generated when the club passes through the sensor 4 is input to the MuD conversion circuit 19 and 20 and converted into a numerical value. After this value is added by an adder circuit 21, each value is added by a divider circuit 22.2 using this value as a divisor.
3 is calculated as the out-of-question rate and is displayed separately on the left and right sides of the 9 display section 2.

As described above, according to the present invention, the amount of weight distributed between both feet when swinging a golf club is detected, and this amount of distribution is displayed with light, so it is easy to change the state of weight transfer during swing. It can be used to effectively correct 7 ohms.
