The conventional hitting practice tool described above has the following problems.
<1> A certain type of device is complicated and expensive, such as determining the trajectory of the hitting unit with a light beam and a sensor, and is not in a range that can be purchased and used by a general golfer.
<2> Other types of devices must use a dedicated club for practice, and require a golfer to purchase a club with such a special structure, which is uneconomical.
<3> When a dedicated club for practice is used, even if it is possible to get an ideal feel of hitting in practice, the same golf club will be used. It is difficult to hit with a sense.

The hitting practice tool of the present invention that has solved the problems of the conventional apparatus as described above is a hitting practice tool that is attached to a hitting member such as a golf putter or a grand golf club, and is a hitting member such as a golf putter. A hitting practice tool to be attached to a hitting body comprising a substantially hemispherical hitting body and a mounting part that can be attached to and removed from a hitting member such as a putter. When a contact detection unit is provided at the farthest end from the sensor, a display unit that converts the signal detected by the detection unit into sound, light, etc., is displayed, and the contact detection unit detects contact with the golf ball. In addition, it is a feature of a hitting practice tool configured to convert a contact signal with a ball into sound, light or the like and display it.

Since the hitting practice tool of the present invention is as described above, the following effects can be obtained.
<1> By using a practice tool with a simple structure, an accurate batting form can be obtained.
<2> When a hit is made with an accurate form, the result can be informed by sound or light, so that the practitioner does not get bored and can practice repeatedly while maintaining interest.
<3> Unlike a complicated and expensive device, a general golfer can easily purchase and use it.
<4> Since a dedicated club is not required for practice, the golfer can practice using his / her club and is economical.
<5> If you can practice with your own club and get a sense of the ideal shot, you can play using the club at the golf course, so remember to hit the same ideal sense. Can do.

Hereinafter, the hitting practice tool of the present invention will be described using golf putters as examples with reference to the drawings.

<1> Overall configuration.
The hitting practice tool of the present invention is a hitting practice tool that is attached to the hitting member A such as a golf putter or a golf club that is held on the ground.
Therefore, any golfer who has a normal putter or club can practice using his / her putter, and there is no need to purchase a special putter.

<2> Hitting ball 1.
The practice tool of the present invention includes a hit ball 1 and a fixed portion 2.
The hitting body 1 is a block body formed in a substantially hemispherical shape, the surface of which is a “spherical surface”, and accommodates a contact detection unit to be described later.
Since the hitting body 1 has a spherical surface, there is only one ideal hitting point that contacts the bolt 24 when hitting.
That is, this one point is the endmost part farthest from the striking member A when the hit ball is attached to the striking member A.

<3> A contact detection unit.
In the curved surface of the hitting body, a contact detection portion is provided at the end most farthest from the hitting member side.
The endmost portion is a so-called sweet spot, which is the most protruding point when the substantially hemispherical hitting portion is viewed from above when attached to the hitting member.
A contact signal between the contact detection unit and the ball is converted into voice, light, etc. and transmitted.

For example, a device having a movable part and opening / closing a contact with mechanical energy to transmit a signal can be used as the contact detection part attached to the substantially hemispherical impacting body.
For example, known switches such as commercially available micro switches and limit switches belong to this range.

As the contact detection unit, for example, a proximity switch that transmits a signal without contact to an object can be used.
For example, an infrared sensor that transmits infrared rays and receives and detects the reflected waves can be employed.
The infrared sensor can employ either a type that uses the character as an infrared heat ray or a type that uses the character as an infrared electromagnetic wave.
Or if the process corresponding to a golf ball is given, proximity switches, such as a high frequency transmission type, a capacitance type, and a magnetic type, can be adopted.
Alternatively, a microwave sensor that transmits microwaves and receives microwaves reflected or attenuated from the ball may be employed.
Alternatively, an ultrasonic sensor that receives long sound waves reflected from the ball with an ultrasonic microphone can be employed.

For example, a pressure sensor that emits a signal from an increase in some resistance values and a decrease in some resistance values by contact with a golf ball can be used as the contact detection unit.
A diffusion-type semiconductor pressure sensor or the like can detect contact at a very limited position because the diameter of the diaphragm, which is a pressure-sensitive portion, is as small as a needle hole (0.8 mm).
Alternatively, a load cell that detects strain generated in proportion to the weight when a load is applied to the strain generating body may be employed.
Alternatively, a switch using a pressurized conductive rubber whose resistance value is rapidly changed from an insulated state to a conductive state by pressurization can be employed.
If a sensor that can detect the difference in the strength of contact with the golf ball is employed as in this example, the transmission can be transmitted in proportion to the impact pressure.

<4> Display unit.
The signal detected by the detection unit is converted into sound, light, etc. by various converters.
The converted signal is displayed on the display unit as sound and light.
A device is known in which a power source is input by opening and closing a switch, a sounding device and a light emitting device are activated, and the result is displayed.
By transmitting sound and light, the user can know that the golf ball has hit the contact detection unit, that is, the sweet spot of the hit ball.

<5> Fixed part 2.
In order to attach the hit ball 1 to the hitting member A such as a putter, the fixing portion 2 is required.
For this purpose, for example, a fixing portion 2 having a U-shaped cross section is employed.
The fixing portion 2 has a cross-sectional "U" shape by a vertical wall plate 21, an upper shelf plate 22 projecting in an orthogonal direction from the upper portion thereof, and a lower shelf plate 23 projecting in an orthogonal direction from its lower end. Form.
The upper shelf board 22 and the lower shelf board 23 project from the wall board 21 in the same direction.
And the space | interval of both shelf boards is comprised by the space | interval wider than the space | interval of the striking surface of the striking member A. FIG.
For example, when the striking member A is a golf putter, the interval between the upper shelf plate 22 and the lower shelf plate 23 is configured to be wider than the interval between the hitting surfaces of the average putter.
A nut hole is opened from the upper shelf plate 22 in the vertical direction, and a bolt 24 is inserted into the nut hole.

<6> Attachment to the striking member A.
In order to attach the hitting body 1 to the striking member A, the striking surface of the striking member A is positioned between the upper shelf plate 22 and the lower shelf plate 23, and bolts 24 are inserted into the nut holes from above and screwed.
Then, since the lower shelf board 23 exists below, the striking surface of the striking member A is firmly tightened from above and below, so that the hit ball 1 can be attached securely.
On the contrary, if the bolt 24 is loosened, it can be easily removed.

<7> Direction indicating rod 3.
A rod-shaped direction indicating rod 3 can be provided in a projecting manner at a position different from the hit ball 1 described above.
For example, the fixture is projected on the vertical end surface of the upper shelf board 22 in the direction opposite to the hit ball 1 and in the direction orthogonal to the wall board 21.
Then, when the fixing portion 2 is accurately attached to the striking member A such as a putter, the direction indicating rod 3 instructs the direction in which the striking member A should be moved.

<8> A mounting method.
Next, as an example of the usage method, an example in which the hitting practice tool of the present invention is used for a golf putter will be described.
First, the striking surface of the putter head is positioned between the upper shelf plate 22 and the lower shelf plate 23 of the fixture, and the bolts 24 are tightened with the wall plate 21 in direct contact with the striking surface.
In this case, it is not necessary to attach at any position of the head, but a fixed attachment position is determined.
That is, the head has a sweet spot where the head force is most efficiently transmitted to the ball when hit.
Therefore, when the practice tool of the present invention is attached to the head, it is arranged and attached so that the apex of the hit ball 1 is located at a position corresponding to the sweet spot of the head.

<9> Strike practice method.
The practice tool of the present invention is attached to the striking surface of the striking member A, for example, a favorite golf putter according to the above-described arrangement. Then hit the golf ball repeatedly.
Since the apex of the hitting body 1 of the practice tool matches the sweet spot as described above, the apex of the hitting body 1 hits the ball if the direction in which the putter is shaken exactly matches the direction to be hit. It hits the apex on the other side.
Then, the ball travels accurately on the hitting line.
In this case, if the practice is repeated with the consciousness of matching the direction of movement of the putter with the direction indicated by the direction indicating rod 3, the technique and intuition of the swing can be quickly acquired.

<10> Display by sound or light.
In the hit ball of the present invention, the curved surface is provided with a contact detection portion at the end most distant from the hitting member side.
And the display part which converts and displays the signal detected by the detection part into sound, light, etc. is provided.
Therefore, when the golf ball hits one point at the extreme end of the curved surface, the contact detection unit detects contact with the golf ball, and converts the contact signal with the ball into sound, light, etc. and displays it.
Therefore, the hitter can know the state by, for example, a light hitting sound or flash when hitting at an accurate position.

<11> When the striking direction and position are shifted.
If the apex of the hit ball 1 and the apex on the ball hitter side do not coincide with each other, the ball travels in a direction away from the hit line.
It is a matter of course that even if the device of the present invention is not used, the hitting line of the ball is shifted due to the putter being inclined or being unable to hit at an accurate position. (Left side of FIG. 5)
However, in particular, the hit ball 1 of the present invention has a spherical surface.
For this reason, a slight misalignment has a great influence and rolls in a direction completely different from the line to be hit. (Right side of Fig. 5)
When the hitter practiced with only the putter as in the past, the shift of the hitting line and the error of the hitting point are expressed only as slight differences.
For that reason, I cannot fully confirm my habit.
However, in the apparatus of the present invention, as described above, the slight deviation is enlarged and expressed greatly, and by seeing the state, it is clearly understood that the sweet spot does not accurately hit the top of the ball hitter side. It is possible that cheating does not work.
In this way, by repeating practice without deception, it is possible to acquire a technique, intuition, and an accurate form for applying the sweet spot to the top of the ball hitting body.
When actually playing at a golf course, if you remove the practice tool of the present invention and use it, you can hit it with the same putter that you used for practice, so you can restore the practice technique as it is. .
If the change in weight when the exercise tool is removed is a problem, the same weight can be attached to the putter.
In addition, although the example used as a hitting member A for a golf putter was described above, it can be attached to a hitting member A such as a gate ball, and in that case, the same effect can be obtained.
