Structural features for achieving the intended purpose of the present invention is the first detection switch is installed in the down blow from the back of the position where the golf ball is placed while being installed under the mat, and down from the front of the position where the golf ball is placed The main switch comprises a second sensing switch installed at a failure position of the blow, and forming a golf practice device that outputs a control signal from a shot sensing device that detects a contact state between the club head and the mat when hitting the golf ball. ; A selection switch connected to the main switch, the selection switch being a first selection switch and a second selection switch switched by a user; The first and second lamps connected to the first selection switch of the selection switch and turned on by a signal output from the shot sensing device, and the shot state is connected by a signal connected to the second selection switch and output from the shot sensing device. Shot state confirmation unit consisting of a sound generating device for outputting a voice; And a lamp lighting maintenance means for causing the first and second lamps of the shot state checking unit to be turned on for a predetermined time and then turned off.

The shot detection device is formed before and after the position where the golf ball is placed, i.e., behind the golf ball that does not form a down blow and in front of the golf ball that forms a down blow. A lower contact plate fixed to the upper surface of the switch plate fixed to the; An upper contact plate disposed to face an upper portion of the lower contact plate at an appropriate distance and having a plurality of switch terminals facing the lower plate; The upper contact plate is provided with an elastic member supporting the lower contact plate to move up and down at a predetermined distance and to perform a switching operation.

This shot detection device is shot by the contact of the switch is made in contact with the lower contact plate by lowering the upper contact plate while compressing the elastic member by the mat is pressed when the club head is passing over the mat during the shot movement of the exerciser The control signal is output by detecting the state of.

At this time, the golf practitioner can visually recognize whether the down blow is successful by the sound effect output from the sound generator such as "Good shot" and "No good". It can be recognized depending on whether you have seen or not seen the lights.

In the present invention, when the upper surface of the mat is pressed by the club head, the switching of the switch inside the mat is made. According to a state in which the first and second selection switches are selected, a specific sound is generated from the sound generating apparatus. The lamp may be turned on, or the sound and the lamp may be operated at the same time.

That is, when the practitioner swings the golf club and hits the golf ball and reaches the position where it continues to draw a parabolic and down blow, the switch under the mat is contacted to hear a specific sound generated by the acoustic generator as the current flows through the circuit. It is possible to know whether the down blow is successful, and even when the swing is not in the down blow position, the down blow is caused by a specific sound.

In addition, if the blower did not see the light of the lamp or the moment of seeing the light would be short, in contrast, if the watch of the lamp for a long time, the practitioner recognizes that the blow is not. In the above process, when the lamp is turned on by the practitioner's swing, it may be difficult to recognize whether the lamp is blown, so it is necessary to keep the lamp on for about 1 to 2 seconds. After seeing what happened, you will be encouraged to keep watching the lamp until it goes out, thus preventing the blow.

In order to effectively practice the blow above, it is necessary to keep the lamp on for a predetermined time with respect to the input signal for lighting the lamp. The present invention can maintain the state in which the lamp is turned on for a predetermined time. As a holding means, the lamp is turned on for about 2-3 seconds and then turned off for a signal input using a relay, a timer, or a microcomputer.

The objects, features and advantages of the present invention will become more fully understood in the light of the accompanying drawings.

As described above, embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a circuit diagram of one embodiment according to the present invention, and FIG. 2 shows a perspective view of a golf practice device.

As shown in FIG. 1, the circuit forming the golf practice apparatus of the present invention includes a main switch 10, a selection switch 11 including first and second selection switches 11b and 11b, and a shot sensing device 12) operated by the acoustic generator 13, the first and second relays 14 and 14a, the first and second lamps 15 and 15a and the first and second relays 14 and 14a. It consists of the 1st, 2nd relay switch 16 * 16a.

The main switch 10 is supplied with Vcc power, and the output side is branched to the input side of the first selection switch 10a and the second selection switch 10b of the selection switch 10.

The first and second selection switches 11a and 11b are power switches for selectively operating the first and second lamps 15 and 15a and the sound generating device 13. The first and second relays 14 and 14a and the first and second lamps 15 and 15a are connected, and the second selection switch 11b is connected to the sound generator 13.

The shot sensing device 12 is composed of two sensing switches including a first sensing switch 11a and a second sensing switch 11b.

In the first sensing switch 11a, the out terminal OUT1 is connected to the enable terminal EN1 and the first relay 14 of the acoustic generator 13, and the out terminal OUT2 of the second sensing switch 11b. ) Is connected to the enable terminal EN2 and the second relay 14a of the acoustic generator 13.

In addition, the shot detection device 12 may be connected to the first and second selection switches 11a and 11b, but may be configured to operate separately by applying a separate driving power source.

The mechanical configuration of the first sensing switch 11a and the second sensing switch 11b is formed by the respective contact points formed between the base 100 and the artificial turf mat 120 as shown in FIGS. 2 to 4. The first detection switch (11a) is installed in front of the position of the golf ball 300 placed on the artificial turf mat 120, the second detection switch (11b) of the golf ball 300 It is formed on the back.

That is, the first sensing switch 11a is formed in the section which makes the down blow, and the second sensing switch 11b is formed in the section which fails the down blow.

The shot detection device 12 is the first detection switch (11a) is turned on (ON) when the club head hits the golf ball 300 through the out terminal (OUT1) of the first detection switch (11a). A control signal indicating that the down blow is successful is output. When the second sensing switch 11b is turned on, the control signal indicates that the down blow has failed through the out terminal OUT2 of the second sensing switch 11b. Outputs a control signal.

The acoustic generator 13 is connected to the shot detection device 12 to control the electrical signal output from the shot detection device 12, that is, a control signal indicating that the down blow is successful, and a control indicating that the down blow has failed. Outputs the sound set in accordance with the signal.

The first relay 14 is excited by a signal output from the out terminal OUT1 of the shot detection device 12 when the down blow is successful, and contacts the first relay switch 16 to light the first lamp 15. , The second relay 14a is excited by a signal output from the out terminal OUT2 of the shot detection device 12 when the down blow fails, and contacts the second relay switch 16a to turn on the second lamp 15a. Let's do it.

Therefore, the first lamp 15 is turned on when the down blow is successful, and the second lamp 15a is turned on when the down blow has failed.

The operation of the circuit configured as described above, first, the first selection switch 11a and the second depending on whether the user turns on the main switch 10 and performs only down blow exercises, or combines down blow and blow exercises. The selection switch 11b may be selected and selected or all selected.

This selection determines whether to drive only the first and second lamps 15 and 15a, only the acoustic generators 13, or to drive the first and second lamps 15 and 15a and the acoustic generators 13. By selecting whether to drive simultaneously, the first and second selection switches 11a and 11b are operated individually.

Therefore, when the first selection switch 11a is set to on, the first and second relays 14 and 14a are ready, and the first and second lamps 15 and 15a are turned on according to the control signal. In this state, when the second selection switch 11b is set to ON, the sound generator 13 is in a ready state.

In the state where the golf exerciser of the present invention is driven, the first selection switch 11 is set to ON if only the practice of blow is felt according to the exerciser's selection. If the two selector switches 11b are set to ON, and both the down blow and the blow practice are to be performed at the same time, the first and second selector switches 11 · 11b may be all set to ON.

In the following description, the first and second lamps 15 and 15a and the acoustic generator 13 are simultaneously driven in order to simultaneously practice down blow and head up.

When the exerciser swings to the club with the first and second selection switches 11a and 11b all set to on, the club head 200 makes contact with the mat 120 as shown in FIG. 6. At this time, when the exerciser performs a normal swing, the club head 200 and the mat 120 come into contact with each other in the advancing direction of the golf ball 300 to operate the first detection switch 11a. When the first detection switch 11a is operated in this way, the output terminal OUT1 of the first detection switch 11a is connected to the enable terminal EN1 of the sound generator 13 and the first relay 14. The first lamp 15 is turned on by the sound generating device 13 and the first relay 14, and at the same time, the sound generating device 13 indicates that the down blow is successful, for example, "good shot" Good shot) "will be output. It is preferable that the time for which the first lamp 15 blinks lasts for about 2 to 3 seconds, and the instantaneous signal generated at the output terminal OUT1 of the shot sensing device 12 is the first relay 14 being the first relay. After driving the switch 16 for 2 to 3 seconds, the first lamp 15 is turned off.

That is, when the exerciser succeeds in the down blow by performing the shot normally, the first lamp 15 lights up to recognize whether the blow is performed, and at the same time, the down blow is successful by the sound output from the sound generator 13. It will be known that.

The first lamp 15 is preferably distinguished from the second lamp 15a and emits green light to inform that the down blow is successful.

Contrary to the above, the second detection switch 11b operates when the exerciser does not make a normal swing and contacts the mat 120 before the club head 200 contacts the golf ball 300. When the second detection switch 11b operates, the output terminal OUT2 of the second detection switch 11b is connected to the enable terminal EN2 of the sound generator 13 and the second relay 14a. The second lamp 15a is turned on by the generator 13 and the second relay 14a. At the same time, the acoustic generator 13 outputs a voice indicating that the down blow failed, such as "no good". Preferably, the second lamp 15a emits red light to easily distinguish from the first lamp 15 while notifying that the down blow has failed.

The time that the second lamp 15a blinks is driven like the first lamp 15 to drive the second relay switch 16a for a predetermined time in the second relay 14a. That is, when the exerciser fails to perform the down blow due to the failure to perform the shot normally, the second lamp 15a is turned on to recognize whether the blow is performed, and at the same time, it is known that the down blow failed from the acoustic generator 13. It will be possible.

As the practitioner sees that the first and second lamps 15 and 15a are turned on for a certain period of time, the first and second lamps are located closer to the reference position where the golf ball dl is placed because the head up is not allowed to practice. It is preferable that the position 15 · 15a is located, and the exerciser performs exercises to prevent the blow while the first and second lamps 15 · 15a are turned on and then turn off after 2 to 3 seconds.

Therefore, the practitioner can practice while recognizing his own shot state by checking the lighting of the first and second lamps 15 占 a and the voice transmitted from the sound generator 13.

The above embodiment includes parts that can be easily modified by those skilled in the art. The parts which can be changed in this way will be described below.

FIG. 1A illustrates another embodiment in which the operation of the first and second relays 14 and 14a and the first and second lamps 15 and 15a and the switch 16 and 16a of FIG. It is a circuit diagram.

Referring to this figure, the signal generated by the shot sensing device 12 and output to the output terminal OUT1 corresponds to the switch 141, and the first relay 14 and the first relay switch 16 are the timer 130. And a resistor (100㏀, 1㏁) and a capacitor (0.1㎌, 2㎌) connected to the timer 130, the first lamp 15 corresponds to the diode 134.

When a signal generated at the output terminal OUT1 of the shot sensing device 12 by the shot of the exerciser is applied to the input of the switch 131, the voltage becomes 0 V at the second input terminal (Trigger, TG) of the timer 130. As the timer operates, the output terminal of 3 becomes high level and terminal 7 (Discharge, DIS) is opened. The capacitor 133 that has always discharged through the seventh terminal is charged through the resistor 132 1 ㏁.

When the voltage reaches 2/3 of the power supply voltage, the output returns to the low level, and the charge accumulated in the capacitor 133 is discharged through the terminal 7.

The time for which the output remains at a high level is determined by the time that the capacitor 133 is charged through the resistor 132 1 ㏁.

This time can be obtained by simply multiplying the capacitor 133 and the resistor 132. For example, in the circuit, 2 seconds can be calculated by multiplying 2 ㎌ (0.000003 F) and 1 ㏁ (1,000,000).

In order to obtain more accurate time, the resistor 132 is set to a variable resistor to input the operation of the switch 131, and the variable resistor is adjusted to measure the time when the diode 134 is operated to obtain an accurate operating time suitable for the exerciser's situation. Can be set.

In this circuit diagram, the diode 134 is connected to the output terminal 3 of the timer 130 so that the diode 134 may be turned on for 2 seconds by the switch 131 operation. Rather than using a circuit diagram of a formula relay, configuring the relay circuit using a semiconductor chip (CHIP) with a CPU function, for example, PIC16C84 or PIC16F84, can minimize errors and The operating time can be set by the set command.

Specifically, the PIC16C84 has one built-in 8-bit timer / counter, and the function as a timer is to generate an interrupt after a predetermined time has elapsed by using an internal clock. The switch 131 The correct time is measured by the operation of the counter according to the input signal of, and when the set time elapses using the internal clock, an interrupt is generated immediately to stop the operation.

In implementing the present invention, it is important to consider mechanical conditions of the first detection switch 11a and the second detection switch 11b for detecting a shot state. This is because the club head moving at a high speed when the exerciser attempts a shot hits the surface of the artificial turf mat 120 so that the detection switch is broken.
