Abstract

A golf ball used for swing practice is provided to help a golf practitioner see a lamp light generated as the club head strikes a golf ball, and to prevent a head-up phenomenon at improved efficiency. A golf ball(10) comprises a rubber-made outer core(12) coated with a cover(11) having numerous dimples formed thereon. A spherical inner core(13) is located at the inside center of the outer core, and a battery(21) and a shock sensor(22) connected via an electrical circuit are mounted on a substrate(20) inserted into the inner core. LED lamps(23) connected to the substrate via wiring are protruded outwardly from the inner core and kept inside the outer core. Preferably, the outer core and the cover are made out of transparent materials, such that the LED lamps illuminate in response to a signal from the shock sensor as a club head strikes the golf ball.

The present invention relates to a golf ball for swing practice, and more particularly, a lamp that is lit by an impact sensor is installed inside the golf ball so that the head of the lamp can be seen when the club head hits the golf ball. The invention relates to an invention that can effectively prevent the head up (turning up) while being heard.

In general, it is very important for a golf game to maintain the correct swing posture that leads to back swing, impact, and follow through. Therefore, the swing practice of golf always maintains the correct swing position so that the correct hit It is important to make it happen.

Among them, the most important part of the golf swing practice is that the club head must see the ball to the end when it hits the golf ball, so that the correct blow can be made to send the ball farther, and to settle the ball on the fairway or the green correctly.

However, most practitioners have a head-up phenomenon, in which the head turns up with the body's rotation before hitting the ball when impacting the ball if there is no strong force on the shoulders or a smooth swing. This occurred and could not hit the ball correctly.

Moreover, novice practitioners could not pinpoint whether they were headed up after hitting the ball, or whether they were headed up before hitting the ball. It became.

The present invention has been made in view of the above problems, the object of which is that the lamp is illuminated by the impact sensor inside the golf ball to see the light of the lamp generated when the club head hit the golf ball It is to provide a swing practice golf ball that can effectively prevent the head-up phenomenon to be rotated while the head is lifted.

A feature of the present invention for achieving the above object, the cover 11 is covered on the outside of the core 12 of the rubber material, the cover 11 in the golf ball 10 formed a myriad of dimples (11a) In addition, a spherical nucleus 13 is positioned at an inner center of the core 12, and a battery 21 and an impact sensor 22 are disposed on an electric circuit in a substrate 20 inserted into the core 13. The LED lamps 23 connected to the substrate 20 and the electric wires are protruded to the outside of the core 13 to be positioned inside the core 12, and the core 12 and the cover 11 are made of a transparent material. When the club head 30 hits the golf ball 10 is formed by the swinging golf ball, characterized in that the LED lamp 23 is turned on by the signal of the impact sensor 22 can be achieved. It is.

Hereinafter, with reference to the accompanying drawings, preferred embodiments for achieving the above object in detail as follows.

1 to 4, the golf ball 10 according to the present invention is covered with a cover 11 on the outside of the rubber core 12, the cover 11 is a myriad of dimples (11a) It has a formed configuration.

In some cases, there are other kinds of golf balls with intermediate coating layers formed between the core 12 and the cover 11. Of course, the structure of the golf ball 10 described above is known in the art.

However, in the present invention, the most important feature is that the LED lamp 23 is built in the golf ball 10 so that the club head 30 hits the golf ball 10 to the signal of the impact sensor 22. The LED lamp 23 is to be turned on by.

That is, a spherical nucleus 13 is located at the inner center of the core 12, and a PCB substrate 20 is inserted into the core 13.

The battery 20 and the impact sensor 22 are connected to the substrate 20 by an electrical circuit, and the LED lamps 23 connected to the substrate 20 by wires protrude out of the core 13 to form a core ( 12) is located inside.

The core 12 and the cover 11 are formed of a transparent material so as to see through the core 13 therein.

Therefore, when the club head 30 hits the golf ball 10 due to the impact, the LED lamp 23 is turned on by the signal of the impact sensor 22 and through the core 12 and the cover 11 of the transparent material. It is configured to be emitted, the LED lamp 23 is configured to be turned off again after being lit for a few seconds by the timer circuit configured in the substrate 20 circuit.

According to the present invention having the above-described configuration, the LED lamp 23 is turned on by the signal of the impact sensor 22 when the club head 30 hits the golf ball 10 due to the impact while practicing the swing of golf. When the user hits the golf ball 10, if the user can see the light of the LED lamp 23 shining on the golf ball 10, the head is turned smoothly in a state where the head up phenomenon is prevented. This is done, if the light of the LED lamp 23 can not see the head up (head up) phenomenon is generated because the user can check the light of the LED lamp 23 can perform a precise and smooth swing practice There is such an advantage.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described embodiments without departing from the spirit of the present invention as claimed in the claims. Various modifications can be made by those skilled in the art, and such modifications are intended to fall within the scope of the appended claims.

According to the present invention as described above, the LED lamp 23 is turned on by the signal of the impact sensor 22 when the club head 30 hits the golf ball 10 when the user practice the swing of golf When the user hits the golf ball 10, the head up phenomenon that the head is turned first by the presence or absence of whether the light of the LED lamp 23 shining on the golf ball 10 can be checked. This will be able to accurately check the problems, such as the occurrence of the user can check the light of the LED lamp (23) to have an advantage, such as accurate and smooth swing practice, can maximize the external competitiveness of the golf ball for swing practice. It is.
