Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a golf practice device that electrically processes various data during the swing of a golf club and can display the data on a display section.

In general, when practicing golf, whether practicing swinging or actually hitting the ball, it is easy to understand how the head of the golf club is catching the ball, as well as the direction in which the ball will fly and the distance it will travel. There is a drawback that it cannot be done. Therefore.

So far, we have been processing all kinds of data from Hitoshi Motoyama all at once when swinging a golf club.

A new golf 41 that can also display the data on a display device! -#Ili! was proposed. However, in such a golf practice device, the detection means detects data on normal swing conditions and displays the data on the display means, and it is possible to detect whether the club head is on the ball or not. Even in the event of a so-called duff, where the club is hit into the grass before impact, if the club head can be swung as it is, the detection means will be activated and the data at that time will be displayed. However, such data cannot be said to be accurate and lacks reliability since the detection means is subjected to shocks etc. before the impact. , the original +IA rudder as a training device cannot be demonstrated.

The present invention has been made in view of the above points, and when the swing does not pass through the proper trajectory, the present invention gives priority to the display of each data by displaying erroneous data. The purpose of this is to provide a nine-golf practice II device that does not display the following information.

An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is a grass-like mat and 2 is a turtle.

Reference numeral 2b designates a pair of magnetic sensors embedded inside the mat near the tee and perpendicular to the swing trajectory of the golf club, and the tee keys are provided equidistantly from each other. 3&, 3b are a pair of magnetic sensors buried within the mat 1 at a predetermined distance in the direction of the swing trajectory of the club and on the artificial side of the magnetic sensors 2&lTo, and both of these magnetic sensors 2.3 are It consists of a permanent magnet and a coil. 4 is an interface circuit that increases the output from these magnetic sensors 2.3 and performs data processing; 5 is an arithmetic processing circuit that operates on the data processed by this interface circuit; b is an arithmetic processing circuit that operates in the swing direction of the club; Magnetic sensors lined up 2&
, 311 and is embedded in the mat 1. This sensor generates an output when the mat 1 is impacted by a club head.

This double detection sensor 6 is connected to an arithmetic processing circuit 5 via an amplification circuit T. Reference numeral 8 denotes a display device that displays each data during the swing calculated by the arithmetic processing circuit 5, and this display device has a display section as shown in FIG. 2. 9. Selectively display the head speed and ball flight by switching a switch. Portion 10 that displays the face angle If with respect to the ball. Head trajectory t-displaying portion 11;
The part of the face showing the impact point of the ball12.
Part 13 showing the ball's launch direction ft. A portion 14 displays the deviation distance of the ball □ in the popping direction.

In the above configuration, when the ball 15 (this ball does not need to be present) that is trapped on the tee is hit, a change in magnetic flux occurs in the magnetic sensor 2.3 due to the sole surface of the club head, and this change in magnetic flux is detected as a signal. The information is sent from the interface circuit 4 to the arithmetic processing circuit 135 and displayed on the display device 8 as various information during the swing. In this case, since the pair of magnetic sensors 1tzb near the tee are located at a position where they can detect the sole surface at the time of ball impact, the conversion process is performed from the ball impact point on the face, the inclination of the club head at the time of impact, and the inclination of this club head. The flight direction of the ball can be calculated by using this method, and the swing speed of the club head can be detected from a pair of magnetic sensors 2 and 3 located in the swing direction, and this data can be processed to calculate the flight distance of the ball. At this time, if we consider the case where the club head H passes through the proper trajectory as shown in Figure 5a, the club head ■ will pass through the bib without hitting the mat 1, or the club head will pass through the bib without hitting the mat 1, or after the ball 1st impact. After hitting the mat 1, the magnetic sensor 2.3 generates a predetermined number 15 due to the passage of the club head H, and then the da7 detection sensor 6 detects a predetermined number 11! In this case, each of the above-mentioned data will be displayed on the display device. On the other hand, as shown in Figure 3,
In the case of
, the da7i detection sensor 6 generates a signal fi- at the same time as the signal generated by the magnetic sensor (FIG. 4b). The signal is sent to the arithmetic processing circuit 5, which determines that the swing is a double swing, and displays g (
Error) is displayed, and no other display is performed at all.

As described above, the present invention comprises a means for detecting the state mt of a golf club during a swing, and a means for processing a detection signal from the detecting means and displaying each data t during the swing. 9 displays each data only when the swing passes through the proper trajectory, and when the swing does not pass, an error display takes priority over each data display, so only valid data is displayed on the 9 display device. It is extremely useful as a training device of this kind.
