BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf practice machine.

0002

2. Description of the Related Art Recently, various golf practice machines have been devised. They range from large-scale ones that use video cameras to simple ones that involve attaching a string to a golf ball and hitting it.

[0003] The goal to be learned by practicing golf is to accurately apply the golf club head to the golf ball. In other words, the motion of a hit golf ball is determined by the short period of time that the golf club head and the golf ball are in contact with each other. Therefore, if it is possible to observe the moment when the golf club head hits the golf ball every time, it is expected that it will be useful for improving one's golf skills.

However, in currently devised golf practice machines, the speed and direction of movement of the golf club head,
In many cases, the passing position can be confirmed. By photographing the vicinity of a golf ball using a high-speed camera and playing it back, you can see how the golf club head is moving in relation to the golf ball. However, it is clear that such a system would be very expensive.

[0005]

[Problem to be Solved by the Invention] In other words, with inexpensive golf practice machines, it is not possible to directly see the state of the golf club head and the golf ball at the moment of contact, which is the part that golf beginners want to know the most.

[0006]

SUMMARY OF THE INVENTION The present invention includes one or more sensors for confirming the passage of a golf club head and the output of the sensor so that the moment when the golf club head hits a golf ball can be observed every time. A processing circuit and
The present invention provides an afterimage type golf practice machine characterized by comprising a strobe that emits light by the output of the circuit.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram of an embodiment of the present invention, in which 1 and 2 are sensors that confirm the passage of a golf club head or golf club shaft, 3 is a circuit that processes the output of the sensor, 4 is a strobe that emits light by the output of the circuit, 5 is a golf ball, and 6 is a golf club head. In order to make the explanation easier to understand, FIG. 1 shows the parts necessary for constructing the present invention, as well as a golf ball 5 and a golf club head 6. As shown in FIG.

FIG. 1 illustrates the moment when a golf club is swung and a golf ball 5 and a golf club head 6 hit each other.

Sensor 1 and sensor 2 are sensors that confirm the passage of a golf club head or a golf club shaft. Circuit 3 receives the outputs of sensor 1 and sensor 2, and
Estimate the club head speed based on the time difference between the outputs,
This circuit determines the timing to cause the strobe 4 to emit light at the moment when the golf club head 6 hits the golf ball 5, and outputs a signal for emitting light.

When the golf ball 5 and the golf club head 6 are in the state shown in FIG. 1, when the strobe 4 emits light for a short time, an afterimage of the golf ball 5 and the golf club head 6 can be seen.

FIG. 2 is a block diagram of another embodiment of the present invention, in which 7 is a sensor for confirming the passage of a golf club head;
8 is a circuit for processing the output of the sensor, 8a is an adjustment knob connected to the circuit, 9 is a strobe that emits light based on the output of the circuit 8, and the golf ball 5 and golf club head 6 are the same as those shown in FIG. In order to make the explanation easier to understand, FIG. 2 illustrates the parts necessary for constructing the present invention, the golf ball 5, and the golf club head 6.

FIG. 2 illustrates the moment when the golf club is swung and the golf ball 5 hits the golf club head 6.

The sensor 7 is a sensor that confirms the passage of the golf club head. The circuit 8 receives the output of the sensor 7,
This is a circuit that outputs a signal that delays and causes the strobe 9 to emit light. The adjustment knob 8a is used to adjust the degree of the delay.

If the adjustment knob 8a is adjusted in accordance with the swing speed of the golf club and the timing of the strobe light 9 is adjusted, when the golf ball 5 and the golf club head 6 are in the position shown in FIG. can be made to emit light.

When the golf ball 5 and the golf club head 6 are in the state shown in FIG. 2, when the strobe light 9 emits light for a short time, an afterimage of the golf ball 5 and the golf club head 6 can be seen.

[0016]

As explained above, the afterimage type golf practice machine of the present invention is very useful for improving golf skills because it allows the player to observe the moment when the golf club head hits the golf ball every time.

If the strobe 4 is made to emit light intermittently, the direction of movement of the golf club head 6 can also be seen.
