Abstract

When the golfer makes the most important part of the golf swing, i.e., from the back swing to the down swing, most of the movements of swing check points after the top naturally become good by performing an ideal body turn of lower body lead. It is intended to permit such an ideal body turn to be mastered, eliminate a commonly termed hand shooting from the top, increase the head speed without irrational force to increase the distance, improve the shot control and produce high level swing form. To realize these intents, a golf swing training device 10 was constructed with detecting means 12 for detecting the contact of the golfer'"'"'s shoulder with the chin or close contact of the former to the latter at the time of the back swing, and notifying means 20 for providing a detection signal to the golfer 18 via a controller 16, and transmitting means 22 and 24 for transmitting to the waist or knee. Further, second detecting means are provided, if necessary.

Claims

1. A golf swing training device, comprising:

detecting means for detecting that one of the shoulders of a golfer is in contact with or closest to the chin when the golfer has gotten into the back swing from the address position,

notifying means for notifying the contact or closest approach detected by said detecting means to the golfer via a controller by a sound or speech,

transmitting means for transmitting signals selected from the group consisting of electric currents, mechanical vibrations and sound waves indicating the contact or closest approach detected by said detecting means to the golfer'"'"'s knee and/or waist on the side of the pivoting foot after weight shift.

3. A golf swing training device according to claim 1 or 2, which further comprises second detecting means for detecting that the golfer'"'"'s other shoulder is in contact with or closest to the chin when the golfer has gotten into the follow-through after the down swing, and notifying means for notifying the contact or closest approach detected by said detecting means to the golfer via a controller.

5. The golf swing training device according to claim 1 or 4, further comprising second momentum detecting means mounted on a golfer'"'"'s arm or the golf club for detecting the momentum at the time of the back swing or the momentum from the down swing to the follow-through, behavior detecting means mounted on the golfer'"'"'s knee and/or waist on the side of the pivoting foot after weight shift for detecting a movement of the knee and/or waist, and judging means for judging a timing according to the detection signals of said second momentum detecting means and behavior detecting means.

6. The golf swing training device according to claim 1, further comprising detecting means mounted on at least either one of the golfer'"'"'s hand and upper body and the golf club for detecting the movement of the mounting spot while a swing is made at least from the address position through the back swing to the top, and notifying means for notifying a change in the movement detected by the detecting means to the golfer.

7. The golf swing training device according to claim 1, further comprising detecting means mounted on at least either one of the golfer'"'"'s hand and upper body and the golf club for detecting the movement of the mounting spot, storage means for continuously or intermittently storing the movement detected by said detecting means, and display means for reproducing and displaying the movement stored in said storage means.

8. The golf swing training means according to one of claims 6 and 7, wherein the movement of the hand, arm or golf club detected by said detecting means is at least either one of the speed, acceleration, momentum and centrifugal force.

2. A golf swing training device, comprising:

momentum detecting means mounted on a golfer'"'"'s arm or the golf club or at least either one of the contact portions of the golfer'"'"'s hand or fingers and the golf club for detecting a change in the momentum slightly before the top at the time of the back swing,

notifying means for notifying a change in the momentum detected by said momentum detecting means to the golfer via a controller by a sound or speech, and

transmitting means for transmitting signals selected from the group consisting of electric currents, mechanical vibrations and sound waves indicating a change in the momentum detected by said detecting means to the golfer'"'"'s knee or waist on the side of the pivoting foot after weight shift.

4. A golf swing training device, comprising:

detecting means for detecting that one of golfer'"'"'s shoulders is in contact with or closest to the chin when the golfer has gotten into the back swing from the address position,

a controller which receives signals from said detecting means, and

transmitting means for transmitting signals selected from the group consisting of electric currents, mechanical vibrations and sound waves indicating the contact or closest approach detected by said detecting means to the golfer'"'"'s knee and/or waist on the side of the pivoting foot after weight shift via said controller.

9. A golf swing training device, comprising:

momentum detecting means mounted on one of a golfer'"'"'s arm and a golf club, and either one of the contact portions of the golfer'"'"'s hand or fingers and the golf club for detecting a change in the momentum before the golfer reaches the top at the time of the back swing, and

transmitting means for transmitting signals selected from the group consisting of electric currents, mechanical vibrations and sound waves indicating a change in the momentum detected by said momentum detecting means to the golfer'"'"'s knee and/or waist on the side of the pivoting foot after weight shift.

10. A golf swing training device, comprising:

pressure detecting means provided on at least either one of contact portions of the golfer'"'"'s thumb and the golf club grip in contact with the thumb for detecting the pressure between the thumb and the contact portion, and

transmitting means for transmitting signals selected from the group consisting of electric currents, mechanical vibrations and sound waves indicating the pressure, when detected by said pressure detecting means, to the golfer'"'"'s knee and/or waste on the side of the pivoting foot after weight shift.
