Description

The present invention relates to a practice aid for correctly learning the basics of starting a club head during takeback in a club swing.

As an auxiliary tool for this kind of club swing practice, Japanese Utility Model Publication No. 61-148368 published utility model “Golf Swing Straightener” (Patent Document 1) is known.

Japanese Utility Model Publication No. 61-148368

Patent Document 1 (Japanese Utility Model Publication No. 61-148368 published utility model) “Golf Swing Straightener” is a club starting orbital assisting tool for takeback swing, bent in the shape of an arc at the tip of an arm that rotates around a support shaft A thin stick (assuming a club head trajectory) is attached, and the back swing is induced by indicating the direction of the club head trajectory during takeback during a shot in golf. That is, the takeback swing is visually induced by a thin bar bent like an arc at the tip of the arm. Therefore, there is a problem that the backswing trajectory to be guided is constant, so that it is not possible to cope with a change in club type or a player with different height.

An object of the present invention is to provide a golf swing start orbit practice assisting tool that can cope with a change in club type and a difference in height of a user.

  The present invention relates to a swing including an arm rotation bearing supported by a support, a golf club shaft guiding arm fixed to the arm rotation bearing device, and a rotation spring for urging the arm rotation bearing device with a rotational force. Providing start-up orbit practice aids.

The present invention accurately assists an initial trajectory for learning the basics of starting a club head when performing a golf swing practice including swing and trial hits by the motion trajectory and speed of a club shaft guiding arm. It is easy to do repeated practice, and you can learn the initial trajectory of the club without any help.
Also, players with different heights, such as wood and iron, can adjust the height and angle of the club shaft guiding arm (starting auxiliary arm) freely, and anyone can learn the ideal swing starting trajectory.

The swing starting orbit training device for golf practice of the present invention is supported by a ground fixing stand 1 composed of a plurality of grounding bodies 10, a support 2 standing upright from the center of the ground fixing stand 1, and the support 2.

Thus, the inclination angle of the shaft 3a of the arm rotation bearing device 3 can be changed freely.

7 and 8, the guide range of the shaft M by the distal end working portion 4a of the club shaft guide arm 4 is set between the rear stop position B and the address position A as shown in FIG. The interval is the induction angle β. C is the start manual position.

Specific examples of FIGS. 7 and 8 will be described in detail below with reference to FIGS.

First, the embodiment shown in FIGS. 10 to 14 will be described.
A support column 2 is erected in the center of a ground fixing stand 1 composed of a plurality of grounding bodies 10, and a support block 8 is provided above the support column 2 via a swing mechanism 7. The strut 2 is equipped with an expansion / contraction mechanism 6.
The support block 8 is equipped with an arm rotation bearing device 3 that supports the shaft 3a to which the club shaft guiding arm 4 is fixed.

A rotation spring 5 for biasing the rotational force to the shaft of the arm rotation bearing device 3 is provided. Referring to FIG. 14, the rotation spring 5 is provided with a lock mechanism 9 and a spring force (speed) adjusting screw 5a.

10 to 14, 12 is a fixing screw for fixing the support column 2 to the ground fixing stand 1, and 13 is a height adjusting lever for expansion / contraction fixing of the expansion / contraction mechanism 6.

The supporting arm rotation bearing device 3 fixes the angle plate 14 having the angle display line 14 a and is equipped with a clamp 15 on the end surface of the shaft 3 a, and the clamp 15 sets the club shaft guiding arm 4 at a fixed position. Fix it freely. Reference numeral 15a denotes a fixing position adjusting screw.

A peripheral surface protector 16 made of a material that is easy to contact with the club shaft is provided at the tip of the club shaft guiding arm.

Next, a second embodiment of the present invention will be described with reference to FIGS.
The second embodiment is the same as the first embodiment shown in FIGS. 10 to 14 except that the rotary spring 5 that biases the rotational force on the shaft of the arm rotary bearing device 3 is equipped with a spring force filling motor 17. A computer control device 18 for the spring force filling motor 17 is provided at the lower part of the support column 2 and other appropriate places.

In the first embodiment of the present invention, the rotating spring 5 can be operated with no power supply for manual operation. In the second embodiment of the present invention, the spring force filling motor is used. 17 and the computer control device 18 can automatically move the club shaft guiding arm 4 to the start position C.

Further, in the third embodiment of the present invention, the shaft of the arm rotary bearing device 3 is equipped with a bidirectional rotary electric motor 26 for applying a rotational force instead of the spring force filling motor 17, thereby providing a computer. Based on a setting command for microcomputer control by the control device 18, the fixed position, rotation start timing, club start start speed, rotation speed, etc. of the club shaft guiding arm 4 can be freely set.

The shape and structure of the ground fixing stand 1 can be changed as appropriate. In the second embodiment, the ground fixing stand 1 is composed of a pair of left and right ground plates 1P and 1P and a connecting plate 1Q.

Further, the ground fixing stand 1 may be omitted, and the support 2 may be directly driven into the ground and fixed, or may be fixed to or removable from the facility equipment of the golf course.

Next, the use procedure of the present invention will be described.
The club shaft guiding arm 4 is stopped by the action of the rotating spring 5 at the rear stop position B which does not interfere with the practice swing.
Before performing the practice swing, the club shaft guiding arm 4 is forcibly rotated and moved to the start position C by some human power, and the brake is temporarily stopped at that position.

Next, after the golf club M is set to the address position P, the club shaft guiding arm 4 temporarily stopped is rotated to return to the rear stop position B by the rotating spring 5 released from the braking action. By the movement, the club shaft M is pushed out in the starting direction from the address position A to the takeback and swing top positions.

By utilizing this function for practice swings, it is possible to acquire the initial trajectory of the golf swing to the swing top position without help from anyone by repeatedly performing the ideal takeback starting method and the trajectory / speed. .

Referring to FIG. 23, the guiding range of shaft M by tip action portion 4a of club shaft guiding arm 4 is guided between the rear stop position B and address position A in the same manner as in FIG. The angle β. C is the start manual position.

In the above embodiment, the golf swing start orbit assisting tool related to correct takeback for golf swing practice has been described. However, the present invention operates the club shaft guiding arm in the direction opposite to the stop position B from the start position. By adopting such a configuration, it can also be applied to practice of swing swing in general swing swing (after hitting the ball).
