A shot state confirmation unit consisting of a sound generator that applies force; a shot state confirmation Lamp point that turns on or off the first or second lamp of a certain section for a certain period of time And a lamp maintaining means;

[0009]   The shot-sensing device is preferably located underneath the mat at the location of the golf ball. Front and back, that is, the front of the golf ball that does not become down blow, and down blow It consists of switches provided at the rear of the golf ball and its components. Is fixed on the upper surface of the switch plate, which is fixed on the base under the mat. Lower contact plate, which is located opposite the upper contact plate at an appropriate distance. Upper contact plate, which is placed and has multiple switch terminals facing the lower contact plate And the upper contact plate has a certain distance from the lower contact plate and moves up and down while moving up and down. And an elastic member that supports so as to perform an etching operation.

[0010]   Such a shot sensing device causes the club head to move when the practitioner makes a shot. The upper contact plate due to the mat being pushed when the surface of the mat is overwhelmed Compresses the elastic member and descends to come into contact with the lower contact plate, When the contact of the switch is turned on, the shot state is sensed and a control signal is output.

[0011]   At this time, the golf practitioner has to say "Good shot" or "No shot". Down blow by sound from a sound generator such as "No good" You can recognize the success or failure of. Also, whether there is a head-up mistake ， It can be recognized while checking the lighting of the lamp.

[0021]   The first selection switch 11a and the second selection switch 11b are connected to the first lamp 15 and the second selection switch 11b. Power switch for selectively operating the lamp 15a and the sound generator 13 Therefore, the first selection switch 11a includes a first relay 14, a second relay 14a, and It is connected to the first lamp 15 and the second lamp 15a. Then, the second selection switch 1 1b is connected to the sound generator 13.

[0022]   The shot sensing device 12 includes a first sensing switch 12a and a second sensing switch 12b. Composed of and.

[0023]   The OUT terminal OUT1 of the first sensing switch 12a is an enable terminal for the sound generator 13. It is connected to the bull terminal EN1 and the first relay 14. And the second sensing switch 1 The output terminal OUT2 of 2b is connected to the enable terminal EN2 of the sound generator 13 and the second terminal OUT2. It is connected to the relay 14a.

[0024]   Further, the shot sensing device 12 is connected to the first and second selection switches 11a and 11b. Can also be connected, and configured to operate separately by applying a separate drive power supply You can also

[0025]   The mechanical structure of the first sensing switch 12a and the second sensing switch 12b is shown in FIG. It is formed between the base 100 and the artificial grass mat 120 as shown in FIG. It is composed of a switch formed by each contact. The first sensing switch 12a is , Provided in front of the position of the golf ball 300 placed on the artificial grass mat 120, The second sensing switch 12b is provided behind the position of the golf ball 300.

[0026]   That is, the first sensing switch 12a is provided in the down blow section, The sensing switch 12b is provided in a section where down blow does not occur.

[0027]   In such a shot sensing device 12, the club head hits the golf ball 300. When hit, the first sensing switch 12a is turned on, and the first sensing switch 12a is turned on. A control signal for notifying the success of the down blow is output from the out terminal OUT1. one On the other hand, when the second sensing switch 12b is turned on, the second sensing switch 12b goes out. From the terminal OUT2, a control signal for notifying the down blow failure is output.

[0028]   The sound generator 13 is connected to the shot sensing device 12, and the shot sensing device 1 An electric signal output from 2, that is, a control signal indicating successful down blow, Distinguish from the control signal that signals a down blow failure. And each set Output the sound.

[0029]   The first relay 14 is an out end of the shot sensing device 12 when the down blow is successful. It is excited by the signal output from the child OUT1 and contacts the first relay switch 16 Then, the first lamp 15 is turned on. On the other hand, the second relay 14a is down blown. At the time of failure, depending on the signal output from the OUT terminal OUT2 of the shot sensing device 12, The second relay switch 16a is contacted to turn on the second lamp 15a. Let

[0030]   Therefore, the first lamp 15 lights up when the down blow is successful, and the second lamp 15a Lights up when down blow fails.

[0031]   The operation of the circuit configured in this way is as follows. First, the practitioner turns on the main switch 10. Set to N and practice down blow practice only, or do down blow practice and head First selection switch 11a and second selection switch 11b is selected and selected, or both are simultaneously selected.

[0032]   Such a selection may be performed by driving only the first and second lamps 15 and 15a, or by producing an acoustic sound. It drives only the raw device 13 or emits sound with the first and second lamps 15 and 15a. Whether to drive the raw device 13 at the same time is selected. And the first and second selection switches 11a and 11b are operated individually.

[0033]   Therefore, when the first selection switch 11a is set to ON, the first and second relays 14, 14a are in the ready state, and the first and second lamps 15, 15a are controlled by the control signal. Lights up. On the other hand, when the second selection switch 11b is set to ON, the sound generator 13 is ready.

[0034]   The driving state of the golf practice device of the present embodiment described above varies depending on the choice of the practitioner. It If the practitioner only needs head-up practice, the first selection switch 1 If 1a is set to ON and only down blow practice is required, the second selection Itch 11b is set to ON, and down blow practice and head up practice are the same. If necessary, turn on the first and second selection switches 11a and 11b at the same time. Set.

[0035]   Next, in order to do the down blow practice and the head up practice at the same time, About driving the second lamps 15 and 15a and the sound generator 13 at the same time explain.

[0036]   With the first and second selection switches 11a and 11b set to ON at the same time, When the learner swings in the club, the club head 200 moves toward the club as shown in FIG. Contact the contact 120. At this time, if the trainee makes the correct swing, The club head 200 and the mat 120 contact each other at a position slightly ahead of the traveling direction of the le 300. When touched, the first sensing switch 12a operates. The first sensing switch 12a operates And the output terminal OUT1 of the first sensing switch 12a is the enable of the sound generator 13. Since it is connected to the terminal EN1 and the first relay 14, the sound generator 13 and And the first lamp 15 is lit by the first relay 14 and at the same time the sound generator 13 A sound that signals the success of the downblow, eg "Good shot" Is output. It is hoped that the lighting time of the first lamp 15 will last for about 2 to 3 seconds. More preferably, it depends on the instantaneous signal generated from the output terminal OUT1 of the shot sensing device 12. After the first relay 14 drives the first relay switch 16 for 2 to 3 seconds, Pump 15 goes out.

[0037]   That is, if the practitioner succeeds in down-blowing with the correct shot, The lighting of the pump 15 informs whether or not the down blow is possible, and at the same time, the sound generator 13 The sound signals the success of the downblow.

[0038]   The first lamp 15 is separated from the second lamp 15a to notify the success of down blow. Therefore, it is desirable to emit, for example, green.

[0039]   On the contrary, if the practitioner cannot swing correctly, the club head 200 will not If the mat 120 is first contacted before the second contact switch 12 b operates. When the second sensing switch 12b operates, the second sensing switch 12b The output terminal OUT2 of the sound generator 13 is connected to the enable terminal EN2 of the sound generator 13 and the second relay. Since it is connected to 14a, the sound generator 13 and the second relay 14a The second lamp 15a lights up. At the same time, the sound generation device 13 is, for example, It outputs a voice saying "Good" to notify the failure of down blow. Second lamp 1 5a can be easily separated from the first lamp 15 to notify the failure of down blow. For example, it is desirable to emit red light.

[0040]   The blinking time of the second lamp 15a is maintained for 2 to 3 seconds like the first lamp 15. As described above, the second relay 14a drives the second relay switch 16a for a certain period of time. It In other words, if the practitioner fails to blow down with a miss shot, The lamp 15a lights up to indicate the presence or absence of a head-up mistake, and at the same time, the sound generator The sound from the unit 13 informs the failure of down blow.

[0041]   The practitioner looks at the first lamp 15 or the second lamp 15a for a certain period of time while watching Be careful not to put up, so practice the correct posture be able to. Therefore, in the vicinity of the reference position of the golf ball, the first ramp 15 and It is desirable to position the second lamp 15a so that the practitioner can Visually confirm that the second lamp 15a goes out 2-3 seconds after it goes on. Practice to prevent head-up.

[0042]   Therefore, the practitioner turns on the first lamp 15 or the second lamp 15a, and By confirming the sound from the sound generator 13, You can practice while being aware.

[0043]   The above-described embodiment is performed by a person having ordinary knowledge in the technical field of the present invention. Includes parts that can be easily changed. Next, regarding the parts that can be changed in this way, Explain.

Also, the operating time can be set by the command word set in the microcomputer. it can.

[0052]   Specifically, PIC16C84 has one built-in 8-bit timer / counter. ing. Explaining the function as a timer, the internal clock is used for a certain period of time. It operates to generate an interrupt after an error. Switch 131 The input clock signal is used to measure the exact time by the operation of the counter, and the internal clock is used. When the set time has elapsed, an immediate interrupt is generated and operation stops .
