Abstract

The present invention relates to a golf training apparatus for cocking and release correction, characterized by a structure configured to, in order to improve flight distance and enhance accuracy during golf, according to the theory of synthesis of forces that "two forces are biggest when they are applied in the same direction", induce a club swing (cocking and release) following an arm swing to be guided along a rotation orbit of extension of the arm swing by a club swing guide and delay the release, without casting and as much as the user desires, by an angle adjustment by a release time controller.

Description

Golf training device for cocking and release correction

The present invention relates to a training device that creates cocking and release to improve distance and improve accuracy in golf.

Cocking and release are club swing techniques that rotate the wrist around the arm following the arm swing around the shoulder. Cocking is a technique of bending the wrist upward when reaching the top of the back swing, and release is a downward swing technique. This is a technology that accelerates the rotational speed of the club head by quickly releasing the cocking at the time of hitting in the down swing. This is a very important core skill in golf.

'When two forces act in the same direction, the sum of the forces is greatest.' According to the theory of force synthesis, the greatest centrifugal force is generated when the club swing following the arm swing is created in a rotating orbit of the arm swing extension. Therefore, in a club swing that rotates around the wrist, the club shaft must be cocked in a rotation path toward the front center of the arm and released in a rotation path in the opposite direction. Additionally, the grip must be held so that the club swings (cocking and releasing) with this rotational trajectory.

Most golfers bend their wrists to the left and right and cast by throwing the club head forward early in the downswing. These prevent the club swing (cocking and release) from being produced in the rotational trajectory of the arm swing extension (23) and late hitting. In addition, as force is applied to the wrist to maintain a club swing trajectory that deviates from the rotation trajectory of the arm swing extension, wrist rotation is not smooth, and the rotation speed of the club head cannot be sufficiently accelerated.

Conventional release training devices have a structure that controls casting using a force acting in the opposite direction of the release, but golfers with poor motor skills have a risk of casting stronger to overcome this force in the opposite direction, and the release is delayed as much as desired. No.

In order to solve the above problems, the present invention,

The club swing (cocking and release) is guided by the rotational trajectory of the arm swing extension that rotates around the shoulder, and during the downswing, cocking is maintained from the top of the back swing and release is achieved at the desired arm swing angle. It was structured.

The present invention has the effect of improving distance and increasing accuracy and completely preventing casting by repeatedly training late hitting, which involves cocking and releasing with a rotating orbit that creates the greatest centrifugal force and delaying release as much as desired. If the grip is incorrect, club swing is not possible, so this has the effect of correcting the grip.

Regarding the above solution, the present invention,

The main body (1) shown in Figure 1, the rotating shaft bolt (2), the club swing guide (3/club swing guid), the release time controller (4/release time controller), the lifting rod (5/lifting rod), and the adjustment bolt (6) /adjust bolt), nut (7/nut), tightening belt (8/tightening belt) and consists of 8 parts, and the main body (1) includes a rotary gear (11/rotary gear) and a solenoid (1s/) as shown in Figure 2. solenoid, brake gear holder (15/break gear holder), brake lever (16/break lever), and battery (17) are installed, and the rotation shaft bolt connector (31) and guide shown in Figure 3 are installed in the club swing guide (3). (32/guid) and shaft holder (33/shaft holder) are installed, and the release time adjuster (4) includes a sliding switch (41/sliding switch) and an electrode plate (42/electrode) shown in FIG. 4 (or sensor ( sensor)] is installed.

In order to make the club swing (cocking and release) into the rotational trajectory of the arm swing extension (64 in Figure 6), the main body (1) is attached to a tightening belt on the front center line of the lower arm (62 in Figure 6) as shown in Figures 1 and 7. It is worn as (8), and one side of the club swing guide (3) is connected to the rotation gear (11 in Figure 2) of the main body (1) with a rotation shaft bolt (2), and the other side is a linear bushing that surrounds the club shaft. ) shaped shaft holder (33) is connected to the golf club so that the club swing guide (3) moves up and down the club shaft according to the club swing (cocking and release) and the main body (1) rotation gear (11 in Figure 2) Rotates and according to the rotation of the rotation gear, the club swing (cocking) is induced to the rotation trajectory (64 in Fig. 6) of the arm swing extension toward the front center line of the arm (62 in Fig. 6) during the backswing, and the same rotation is performed during the downswing. The structure is designed to induce club swing (release) in the opposite direction of the trajectory.

In order to delay the release as much as desired without casting, the main body rotation gear (11 in Figure 2), which is linked to the club swing by the club swing guide (3), rotates as shown in Figure 2 so that the rotation is rotated during the backswing and the rotation is braked during the downswing. The teeth of the gear 11 and the braking gear 12 are made into the shape shown in FIG. 5, and the plunger of the solenoid (1s/solenoid) is made into the braking gear 12 so that it engages with the rotating gear 11. As the nut 7 is moved by the adjustment bolt 6 shown in FIG. 1, the lifter 5 connected to the nut 7 raises and lowers the angle of the release time adjuster 4, thereby adjusting the angle of the release time adjuster 4. When the arm swing angle is adjusted below the horizontal at the desired release point, the sliding switch (41/sliding switch in Figure 4) moves while passing the arm swing angle at the desired release point during downswing, as shown in Figure 7, and the electrode plate (Figure 4) While passing through 42/electrode (or sensor), the power is connected and the braking gear is pulled by the operation of the solenoid (1s in Figure 2), and the brake gear holder (15 in Figure 2) maintains this state so that the solenoid It was designed so that when it is released with an operating sound, the rotating gear rotates. If there is casting before the solenoid operates, the solenoid, which has a weak pulling force, cannot pull the braking gear, making release impossible. This is a structure that completely prevents casting.

The pulled braking gear is structured so that when the braking lever (16 in FIG. 2) is pushed after completing address, it is engaged with the rotating gear by the spring of the solenoid (13 in FIG. 2).
