JPH1189988A - Golf swing practice apparatus - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a golf swing practice apparatus which allows learning the correct timing of the impact of a golf swing while listening to sounds. SOLUTION: A plate spring 2 is secured to a base 1 at one end and has a weight 4 mounted at the other end, and a receiving plate 5 for issuing sounds when the weight 4 strikes it is mounted on the base 1. This device is mounted on the shaft 6 of a golf club to practice swinging the golf club.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION A golf swing trainer used by a golfer to learn the timing of a golf swing more quickly by expressing the "bend" of the shaft of a golf club more prominently than a normal golf club.

[0002]

2. Description of the Related Art There are many devices for checking the trajectory and the like of a golf swing, but there is no golf practice device that can easily confirm the bending of a shaft of a golf club.

[0003]

Since the head of a heavy golf club is accelerated in the course of a downswing, the shaft is opposite to the swing direction, and energy is stored in the shaft. It is a prerequisite for a swing to return to bending and transmit energy to the golf ball at the time of impact. Many golfers do not effectively use the energy stored in the shaft, often reducing the flight distance of the golf ball and deteriorating the directionality. The present invention has been made to eliminate these disadvantages.

[0004]

The embodiments of the present invention will be described below. As shown in FIG. 1, the natural frequency is the same as that of a normal golf club, but the “bend” is large, and one end of a leaf spring (2) is fixed to the base (1). A weight (4) is attached to the other end of the leaf spring (2). To emit a sound when the weight (4) hits the base (1),
A receiving plate (5) is attached. This device is mounted on the tip of a golf club shaft (6) or a dedicated rod,
By performing a swing, weight (4) at the time of impact
He heard that he hit the receiving plate (5) and made a sound, and could confirm the bending of the shaft (6) of the golf club in association with the movement of the weight (4). The present invention is a golf swing training device having the above configuration.

[0005]

The present apparatus is mounted on a golf club shaft (6) or a dedicated rod. A swing is performed to confirm that the weight (4) hits the receiving plate (5) and emits a resonance sound when the head returns at the position of the impact.

[0006]

Embodiments of the present invention will be described below. In FIG. 1, (a) one end of a leaf spring (2) is fixed to a base (1), and a weight (4) is attached to the other end. (B) The base (1) is provided with a receiving plate (5) for emitting a sound when the weight (4) hits. (C) The leaf spring (2) is set so as to be soft in the swing direction and hard in the direction perpendicular to the swing. (D) A golf club shaft (6) is provided on the base (1).
And a mounting portion (3) that can be mounted on the device. The present invention has the above-described structure, and when this is used, the present device is attached to the shaft (6) close to the head of the golf club, behind the swing direction. The attached golf club performs a swing, so that the weight (4) hits the receiving plate (5) at impact when a correct swing is performed, but hits the receiving plate (5) when the swing is not normal. The sound is delayed or advanced, and sounds at times other than impact.

FIG. 2 shows a modification of the leaf spring (2),
A coil spring (7) in which a flexible flat plate (8) is set inside so as not to bend in the direction perpendicular to the swing.

FIG. 3 shows that a resonance tool (9) having the same weight as the weight (4) is used to increase the resonance sound when it hits the receiving plate (5).

[0009]

According to the present invention, when a golf club to which the present apparatus is attached swings and a normal swing is performed, the weight (4) hits the receiving plate (5) at the time of impact.
Emits a sound. You can practice swing while feeling the sound at impact.
