Practice Safe Golf Club {A SAFETY GOLF CLUB FOR PRACTICE}

The present invention relates to a safe golf club for practice, and more particularly to a safe golf club for practice that can be used safely for infants and young children.

In general, golf (Golf) is one of the sports widely enjoyed in the world, including the United States, the interest in golf sports is gradually increasing in Korea.

In addition, demand for golf equipment such as golf clubs is increasing.

Conventional golf clubs are composed of shafts, grips and heads, and most of these golf clubs are made for adults, which is not only expensive for infants and children to use for recreation or practice, but also its material. Due to its nature, there is a safety problem.

In consideration of the above, a plastic golf club for infants and children has recently been introduced.

However, plastic golf clubs are not only easily damaged because they are simply made as toys, but also have a problem that children and children get tired easily, and lack of realism in their materials, etc. There is a limit.

On the other hand, Korean Laid-Open Patent Publication No. 2004-0083189 discloses a club head of aluminum; One side is coupled to the club head, the other is disclosed as a toy golf club made of a shaft packed with a handle.

Toy golf clubs having the structure as described above has the advantage that children can play golf as a sport with a sense of reality, but because the club head made of hard aluminum material is still safe for use by infants and children who are not careful. Of course, there is a problem, and there is a disadvantage that the manufacturing cost is very high to use for the supply.

And since the structure of the handle is formed in the same way as the adult golf club, it is difficult for the infant or child who does not have a basic knowledge of golf to acquire a gripping position.

The object of the present invention is to provide a safety golf club for practice that can secure the safety and economics as well as learn the gripping action naturally.

Practice safety golf club according to the present invention, the shaft (shaft); A grip coupled to one end of the shaft and gradually expanding in diameter toward the tip; It is provided at the other end of the shaft, and includes a rubber head having a coupling portion coupled to the shaft and a body portion integrally formed from the coupling portion, the coupling portion on the outer peripheral surface of the shaft There is a technical feature to being tightly coupled.

It is preferable that any one of an outer circumferential surface of the shaft and an inner circumferential surface of the coupling portion is formed with a ring-shaped separation preventing projection, and the other is formed with a separation prevention groove corresponding to the separation preventing projection.

Of course, it is preferable that the coupling part has an elongated insertion hole formed in close contact with the outer circumferential surface of the shaft, and an inner space is formed in the body part.

Preferably, a plurality of finger guide grooves are formed on an outer surface of the grip to guide the position of the finger accurately during the gripping operation.

According to the present invention, the head of the golf club is made of a rubber material to ensure the maximum safety even if careless behavior or sudden situation of the infant or child occurs, the impact is transmitted to the grip even when hitting the floor during the swing operation Can be alleviated.

In addition, there is an advantage that the inner space is formed in the body portion of the head can further enhance the safety.

In addition, various types of heads can be selectively replaced and used through the coupling part, and the coupling and detachment to the shaft can be easily performed without a separate coupling means due to the material properties of the coupling part.

Meanwhile, the gripping operation may be naturally acquired through the finger guide groove formed in the grip.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in Figures 1 to 4, the practice safety golf club 10 according to the present invention comprises a shaft (shaft) 20; A grip 30 coupled to one end of the shaft 20; It is configured to include a rubber head (40) provided at the other end of the shaft (20).

The shaft 20 has a long pipe structure and is made of graphite material.

Graphite material can provide a sense of reality, and the weight is not only light, but also has the advantage of reducing the impact is suitable as a material of the shaft 20 used for infants or children.

The grip 30 is preferably made of a material having a relatively good grip, such as rubber, and has a structure that gradually increases in diameter toward the tip to effectively prevent the golf club 10 from being missed during the swing operation. It is desirable to have.

As the material of the grip 30, it is possible to selectively apply various kinds of known materials having excellent grip feeling.

In addition, a plurality of finger guide grooves 32 in which a finger is stably seated during a gripping operation are formed in a specific shape on an outer surface of the grip 30. That is, a plurality of finger guide grooves 32 are formed on the outer surface of the grip 30 so as to easily and accurately guide the position of a finger during a gripping operation as shown in FIG. 5.

Accordingly, accurate gripping operation can be easily and naturally acquired without additional calibration.

The head 40 is preferably made of a soft natural rubber material in consideration of safety and risk.

Head 40 is a coupling portion 42 forcibly inserted into the shaft 20; It consists of a body portion 44 extending integrally from the coupling portion 42.

The coupling part 42 is able to be in close contact with the outer circumferential surface of the shaft 20 completely due to its material property, so that the coupling part 42 can be easily coupled / detached to the shaft 20 without a separate coupling means, and the coupling state thereof is better. It can keep solid and stable. The coupling portion 42 is formed with a long insertion hole 43 is inserted in close contact with the outer peripheral surface of the shaft 20, the inner diameter of the insertion hole 43 should be formed smaller than the outer diameter of the shaft 20, of course. .

As such, the head 40 can be easily separated from the shaft 20 through the coupling part 42, so that partial replacement is possible when the head 40 or the shaft 20 is damaged, thereby improving maintenance. In addition, there is an advantage that can be used by replacing the various types of head 40.

Body portion 44 preferably has a structure in which the inner space 45 is formed to increase the safety.

Figure 6 is a cross-sectional view showing another embodiment of the shaft and head coupling structure of the practice safety golf club according to the present invention.

As shown in the figure, the separation prevention protrusion 21 is formed on the outer peripheral surface of the shaft 20, the separation prevention groove corresponding to the separation prevention protrusion 21 on the inner peripheral surface of the coupling portion 42 of the head 40. (41) is formed.

Accordingly, the plurality of separation preventing grooves 41 formed on the inner circumferential surface of the engaging portion 42 of the head 40 by forcibly inserting the engaging portion 42 of the head 40 onto the outer circumferential surface of the shaft 20 are formed in the shaft. The plurality of separation preventing protrusions 21 formed on the outer circumferential surface of the 20 may be elastically coupled to maintain a more firm and stable coupling state of the head 40 and the shaft 20.

The anti-separation protrusion 21 is formed in a ring shape along the outer circumferential surface of the shaft 20, and the anti-separation groove 41 is also ring-shaped along the inner circumferential surface of the coupling part 42 of the head 40 so as to correspond to the anti-separation protrusion 21. Is formed.

On the other hand, the departure prevention protrusion 21 and the departure prevention groove 41 may be formed on at least one of the outer peripheral surface of the shaft 20 and the inner peripheral surface of the coupling portion 42 of the head 40, the number and arrangement The head 40 can be appropriately changed as necessary within the range capable of firmly maintaining the engaged state.
