Description

Field of technology

The present invention is a practice golf club for reproducing, checking, and controlling the impact zone of a golf swing.

Even if you practice golf, you don't always have to hit a lot of balls.
It will improve only if you understand and experience the importance of the impact zone as a process to let your body remember the ideal swing.
And an assistant dry har that can easily correct the swing and assist

Conventionally, as a practice tool of this type, a simple practice club described in Patent Document 1 is known. This practice club has different light emitting sources on the head, and some can confirm the trajectory by opening and closing the head.

Then, depending on the trajectory of the illuminant, the purpose of hitting with the core of the club head, straight flying ball, draw, fade, etc. is described.

Japanese Unexamined Patent Publication No. 10-5381

According to the prior art according to the above-mentioned Patent Document 1, it is a very natural body that the club face opens and closes on the swing trajectory, and expressing the ball muscle at one point on the trajectory is slightly uncomfortable and has a problem. There is.

Therefore, it is an object of the present invention to solve the above-mentioned problems in the prior art and to newly install a more accurate opening / closing degree FIG. 1 (8) regarding the opening / closing of the head and provide it as an assistant club.

In order to solve this problem, it is an object of the present (Patent Document 1) to provide a new assistant club as a means of solving the problem by improving the accuracy of the square impact.

In order to reproduce the impact, the heads Fig. 1 (3) and (7) are equipped with different color illuminants, and the sensor inside the head is driven from the battery in the grip end during the swing process, as shown in Fig. 1 (3). The light emitter of (7) is turned on, and the direction of the flying ball can be confirmed by the positions of the two colors (Fig. 2, Fig. 3, and Fig. 4) at the light emitting sources of FIGS. 1 (3) and (7) immediately before the impact. ..
In addition, we have a newly developed sensor inside the head, which emits light only during the swing process, and we were able to save a lot of power consumption.
Since it has two LEDs with a diameter of 5 mm and 3.3 V, it was dazzling when viewed directly in a stationary state (at the time of addressing), and it felt pressure and was solved by having a sensor.

Opening / closing angle adjustment function Newly equipped with Fig. 1 (8) Shaft flex Shaft kick point (bending position) Ball position, etc. Alignment of opening / closing angle Fig. 1 (8) is indispensable according to individual differences. A swing check practice club featuring the ability to align the opening and closing angles of 1 (9) to (10).

In the present invention, in order to make the square impact easier to understand, the structure of the club was clarified and the main points of the impact were shown.
(1) The grip position of the address is an inverted triangle (Fig. 8 (33)), and it is generally held in the center.
(2) Since the position of the impact grip moves about 10 cm in the target direction in FIG. 8 (34) from the time of addressing, the face angle also opens a little.
▲ 3 ▼ In the downswing, the weight of the head and the center of gravity of the head Fig. 1 (12) are located on the opposite side of the target direction, and the shaft is bowed (twisted to 35 to open the face. ▲ 4 ▼ Immediately before impact When the shaft twisted in a bow shape returns to the target direction due to the reaction of the center of gravity in FIG. 1 (12), it becomes an inverted bow shape in FIG. 9 (36), the phenomenon of twisting back occurs, and the face angle also changes to a closing motion. Immediately before the contact, it can be confirmed by image analysis of the high-speed camera that the face is open at about 9 degrees in FIGS. 10 and 11.
According to the description written by the researchers, it is said that the ball touches and moves with impact, and the ball moves in close contact for 0.5 milliseconds and 2 to 3 cm.
(6) Since the movement of the object has inertia, the phenomenon of twisting back works smoothly from just before the contact time, so the direction of the face when the ball separates after the close contact movement becomes the maximum point. For that purpose, support for shaft rotation is indispensable.

It can be measured with a measuring instrument, but a moment of 1/2500 second cannot be detected by humans. In order to make the swing check easier only by visually observing the complicated moment, we clarified it by imitating the actual product with reference to 11 (1) to (6) above, and designed the reproduction of the impact for practice. There were various conditions regarding the opening of the face angle of 9 degrees just before the impact.
There is an error in the direction of the face, that is, the opening / closing angle due to individual differences such as head speed, shaft flex, shaft kick point, etc., and the present invention has an opening / closing adjustment function to satisfy the opening / closing of the face angle to individual conditions. The point is that the opening and closing degree at speed (40 m / sec) and the ball separation position at about 5 degrees can be clarified at a scary angle.

There are other systems that analyze the swing and check it on the monitor, but few can be seen directly by oneself. If there is a space for swinging, you can easily practice repeatedly if you can see it anywhere, and you can improve your swing skills.

It is seen by professionals and some athletes that the ball can be touched and moved for a long time while keeping the face surface square with respect to the target direction.
Originally, golf clubs have a structure that makes it easy for sliced balls (rotating clockwise) to come out. We will provide a specially devised assistant golf club that will be a shortcut for improvement only if you can understand such a principle.

Form for carrying out the device

The assistant club of the first embodiment of the present invention will be described with reference to FIG.
As shown in Fig. 1, the assistant club is composed of parts with the same specifications as the head, shaft, and grip for playing golf, so there is no discomfort in the swing, and you can feel the uniqueness of the club in particular. What you get is very big.

The battery case (20) shown in FIG. 1 contains two AAA batteries and is compactly housed in the shaft. LED lamp with 2 AAA batteries and 3V power supply 3.3V 20m ampere Figure (2) and (3) Normal battery life can be used for about 300 hours continuously by using two sensors (Fig. 6) ), It emits light at the center of the swing, the battery loss is greatly reduced, and it is easy on the eyes and the power consumption is also greatly saved.

(8) shown in FIG. 1 has a function of adjusting the degree of opening / closing, and the ball flies depending on the position where the LED lamp of (3) and the LED lamp of (7) different colors cross in the swing. The biggest feature is that it is designed so that the direction of the ball is the decisive factor.
