GOLF CLUB FOR SHOWING SWING CONDITION
A golf club for showing swing condition has a shaft and a head connecting to the shaft, and the head having a striking face. The golf club has a visible illuminant that is mounted on the head and exposed outside the head with an upward angle. A battery is for providing electrical power to the light. A centrifugal switch that is actuated by centrifugal force is mounted on the head opposite the striking face for controlling a circuit between the battery and the illuminant. Thereby the illuminant will light by a predetermined-strength centrifugal force during swinging the golf club for investigating the body harmony and strength-exerting condition of golfer.
1. Field of the Invention
The present invention relates to a golf club for showing swing condition, and particularly to a golf club with an illuminate lighting by a predetermined-strength centrifugal force during swinging the golf club for being an education tool.
2. Description of the Prior Art
Golf is a game of ever increasing popularity, and it requires a player to precisely and accurately control both the point at which the club face strikes the ball, and the path of travel of the club, before, during and after contact with the ball. Such control is important in all aspects of the game, but is particularly important when it comes to putting.
A number of aiming devices have been developed to aid golfers in controlling and directing their strokes; but the art has not acknowledged the need for, or provided any, device for tracking the motion of a golf club.
While there are many aiming devices known in the prior art, such devices suffer from a number of shortcomings. First of all, these devices do not provide any means by which a point on a moving club may be tracked. Furthermore, some prior art devices require laser light device, that must avoid to hurt eyes and exists a hidden dangerous.
There is presently, and there has been a consistent problem regarding the golf club of prior art.
SUMMARY OF THE INVENTIONThe main object of the present invention is to provide a golf club for showing swing condition, particular to a golf club can show the force-exerting condition of the golfer during swinging for observing by coach as an education tool.
In order to achieve the above object, the present invention provides a golf club for showing swing condition having a shaft and a head connecting to the shaft, and the head having a striking face. The golf club has a visible illuminant that is mounted in the head and exposed outside the head with an upward angle; a battery is for providing electrical power to the light; and a centrifugal switch that is actuated by centrifugal force and mounted on the head opposite the striking face for controlling a circuit between the battery and the illuminant thereby the illuminant will illuminate by a predetermined-strength centrifugal force during swinging the golf club for investigating the body harmony and strength-exerting condition of golfer.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to
The golf club 1 has an illuminant 4 that is mounted in the head 3 and exposed outside the head 3 with an upward angle, a proper amount of battery 5 that is for providing electrical power to the illuminant 4, and a centrifugal switch 6 actuated by centrifugal force for controlling the illuminant 4 on or off. The centrifugal switch 6 is fixed on a surface opposite the striking face 32 of the golf club 1 for controlling a circuit between the battery 5 and the illuminant 4.
The illuminant 4 must be a visible illuminant, and it can be a LED (Light Emitting Diode) or a light bulb. LED is cheaper and brighter, and also has various colors for selecting. The direction of the illuminant 4 is substantially parallel to the shaft 2 for observing the swing condition of the golfer. The illuminant 4 will light by a predetermined-strength centrifugal force during swinging the golf club.
In this embodiment of the present invention, the centrifugal switch 6 comprises an elastic control pole 61 and a fixed pole 62 that is fixed on the head 3. The control pole 61 moves along a direction of centrifugal force during swinging the golf club 1 to contact with the fixed pole 62. In which, the control pole 61 has a first fixed portion 63 that is fixed on the head 3, an elastic portion 65 that is extending upwardly from the first fixed portion 63, and a movable first contact portion 67 that is connecting with the elastic portion 65. The fixed pole 62 has a second fixed portion 64 that is fixed on the head 3 and a second contact portion 66 that is connecting with the second fixed portion 64 and positioned on a moving path of the first contact portion 67.
A positive contact of the illuminant 4 is connecting with a positive electrode of the battery 5, and a negative contact of the illuminant 4 is connecting with the control pole 61 of the centrifugal switch 6. The fixed pole 62 of the centrifugal switch 6 is connecting to a negative electrode (not labeled) of the battery 5. The battery 5 is fixed in a plastic seat.
The illuminant 4, the battery 5 and the centrifugal switch 6 could be fixed on the head 3 by adhesive 36, for example by silicon, and fixed on the back 34 of the head 3. The battery 5 is not limited to be mounted on the head 3. The battery 5 can also be mounted on the shaft 2 for avoiding from loosening via impact of string.

The detachable cover 7 also can be mounted on the bottom shell 70 by screwing on screw hole 71 thereof, and the cover 7 also comprises a light hole 72 for exposing the illuminant 4 outside, a detachable battery cover 74 that is mounted on the cover 7 for replacing the battery 5.

In another word, if the illuminant 4 lighting means the golf club 1 reaching a predetermine velocity and resulting a predetermine force strength. Normally, the illuminant 4 should light at the V3 section, and the illuminant 4 should not light at upper section because the centrifugal force is weaker.

To sum up the advantages and functions of the present invention are as followed:
1. The golf club for showing swing condition can use as a golf education tool. The centrifugal switch can show the body harmony and strength-exerting condition of golfer during swinging process.
2. The golf club also can show the swing path for forecasting the ball falling point. When the swing path is curved inwardly, or lineally, or outwardly, that will cause ball flying differently.
3. The golf club for showing swing condition can cooperate with video-recording and provide the coach an analysis means.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrate only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
