Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates in particular to a sensor array for a golf practice device.

In golf, it is important to keep the pole as close as possible to the target point, so it is necessary to practice so that the flight distance and direction of the ball are always constant. This was based on the advice 9 of the practitioner or the practitioner's own subjective opinion, which was extremely frustrating.

In particular, the launch direction of the pole is related to the angle of deviation of the club face at the moment of impact, and being objectively aware of this has a great effect on improving the correct swing.

This invention has been made in view of the above points, and includes arranging a first and second sensor at a predetermined interval in the direction of the swing trajectory of a golf club on one side of the swing trajectory of the golf club divided by the trajectory center line. By arranging a third sensor on the other side, the present invention aims to provide a golf practice device that can calculate and display the flight distance of the ball and the deviation angle of the club face.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is a club head of a golf club, 11 is a face surface of this club head, 2 is a base consisting of a grass-like golf mat 3 and a pace mat 5 on which a tee 4 is set up at a predetermined position; 62.63 is located near the hitting entrance side of the tee 4 provided on the center line R on the ideal swing trajectory of the pacemat 5, and within the swing trajectory on the proximal side of the center line R. Spacing - (e.g. 30fi
) and at a predetermined interval 11 (for example, 501) in the direction of the orbit, the first and second magnetic sensors 63 are opposite to the first magnetic sensor 62 with respect to the center line R. A third magnetic cell is disposed at a predetermined distance from the center line R within the orbit. Moreover, these first, second, and third magnetic sensors 62, 63, and 61 have permanent magnets 72 and 73, respectively.
・71 and a coil 8 wound a predetermined number of times around these permanent magnets.
It consists of 2, 83, and 81. Reference numeral 9 denotes a display device 15 having a processing unit 14 that processes the detection signals of the moving club head 1 generated from these sensors to calculate the flight distance of the ball 13 and the deviation angle of the club head face surface.
1 is a display section that displays the above calculation results, and 12 is a club selection key.

Next, the processing section 14 will be explained based on FIG.
17 is a time difference measurement unit that detects the time tl required for the club head 1 to move through the distance 11 between the second magnetic sensor 63 and the first magnetic sensor 62, and 17 is a calculation unit for calculating, for example, 11÷t1 based on this time tl. a club head speed calculation unit 18 that calculates the swing speed of the club head 1 by
The player stores club data set in advance for each club, selects desired club data using the club selection key 12, and calculates the flight distance of the ball by calculating the club data and the above-mentioned head speed. This is the flight distance calculation section. 19 is a first magnetic sensor 62 and a third magnetic sensor 62;
Detection time difference t2 of the club head 1 with the magnetic sensor 61 of
Based on this time difference υ, the time difference measurement unit 20 calculates the angle α as shown in FIG.
With the above configuration, when a predetermined swing is made, the movement state of the golf club head 1 is detected by the sensors 61, 62, and 63. In response to the detection signal, the time difference measurement units 16 and 19 detect the time difference between the sensors, and calculate the time difference through the club head speed calculation unit 17, the ball flight distance calculation unit 18, and the face deviation angle calculation unit 20, respectively. The flight distance of the ball and the face deviation angle are displayed on the display section 15.

Note that the present invention is not limited to magnetic sensors, and any sensor that can detect the passing state of the club head may be used, and a more detailed display can be achieved by providing four or more sensors.

Therefore, according to the present invention, the first and second sensors are arranged at a predetermined interval in the direction of the swing trajectory of the golf club on one side divided by the center line, and the third sensor is arranged on the other side. By arranging the ball flight distance,
It is possible to provide a golf practice device that can quickly calculate and display the deviation angle of a club face as accurate objective information.
