Description
BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a golf club in which at least one through hole is formed in a hitting surface of a golf club head and a mesh portion is formed using like wire therein. The golf club is light in weight and is short in flying distance of a ball to thereby enjoy golf even in a small area such as in the building or a mini golf course.

2. Description of Related Art

In general, golf is a sport which inserts a ball in a hole by hitting a ball with a golf club on a vastly open land such as a golf course. The golf is recently on a trend to be popularized as one of popular sports.

The golf club hitting a golf ball includes a driver having a long flying distance, an iron to send a golf ball from a fairway to a green, and a putter to insert a ball in a hole from a green. A golfer chooses a golf club to hit a golf ball according to a use purpose, for example, in consideration of a flying distance adjustment or a putting accuracy.

A configuration of a conventional golf club will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic view of a conventional golf club, and FIG. 2 is an enlarged view of a principal part of FIG. 1. The conventional golf club includes a grip 1, a head 3 for hitting a golf ball, and a shaft 2 for coupling the grip 1 and the head 3. The head 3 includes a hitting surface 4 for hitting a golf ball and a body portion 5 for surrounding and supporting the hitting surface 4. The hitting surface 4 and the body portion 5 are made of a weight metal to increase a flying distance of a golf ball because there is a golf game on a vastly open land such as a golf course usually.

However, the conventional golf club is not suitable for the old and the weak and the child because it is very heavy. Further, because the conventional has a long flying distance, a golf game is almost impossible to enjoy in a small area such as in the building or a mini golf course. Therefore, there is a need for a golf club which can solve these problems.

SUMMARY OF THE INVENTION

To overcome the problems described above, preferred embodiments of the present invention provide a soft golf club in which at least one through hole horizontally penetrating a hitting surface of a golf club head is arranged and a mesh portion is formed using a wire in the through hole, so that the golf club is light in weight and is short in flying distance of a ball to thereby enjoy golf even in a small area such as in the building or a mini golf course.

In order to achieve the above object, the preferred embodiments of the present invention provide a soft golf club including a head having a hitting surface to hit a golf ball and a shaft supporting the head. The head includes a through hole horizontally penetrating the hitting surface, a through hole frame defining the through hole, and a mesh portion formed in the through hole in a net form by wires woven with the through hole frame. Or, the head includes a plurality of through holes horizontally penetrating the hitting surface, and a lattice portion defining the plurality of the through holes and formed integrally.

Preferably, the head is made of one of metal, polymer and composite material, and the wire is made of one of metal, non-ferrous metal, alloy, elastic fiber, and synthetic fabrics.

BRIEF DESCRIPTION OF THE DRAWINGS

For a more complete understanding of the present invention and the advantages thereof, reference is now made to the following descriptions taken in conjunction with the accompanying drawings, in which like reference numerals denote like parts, and in which:

FIG. 1 is a schematic view of a conventional golf club;

FIG. 2 is an enlarged view of a principal part of FIG. 1;

FIG. 3 is an enlarged view illustrating a cross section of a golf club head according to a first embodiment of the present invention; and

FIG. 4 is an enlarged view illustrating a cross section of a golf club head according to a second embodiment of the present invention.

DETAILED DESCRIPTION OF PREFFERED EMBODIMENTS

Reference will now be made in detail to preferred embodiments of the present invention, example of which is illustrated in the accompanying drawings.

FIG. 3 is an enlarged view illustrating a cross section of a head of a soft golf club according to a first embodiment of the present invention.

A head 3 is made of one of metal, polymer and composite material. The head 3 includes a through hole 4 formed by horizontally penetrating a hitting surface thereof, a through hole frame 5 defining the through hole 4, and a mesh portion (reference numeral not shown) formed in net form using a wire W in the through hole frame 5.

In more detail, a plurality of wires W penetrates predetermined portion of the through hole frame 5 to be arranged to cross each other, so that the mesh portion is formed throughout a front surface of the through hole 4.

The mesh portion has a configuration that the wires are arranged in the same form as silk fabrics that a weft and a wrap are arranged to cross each other up and down and right and left, so that a drag force required when hitting a golf ball is improved, thereby preventing a damage of the wires W.

As a result, a total weight of the golf club is reduced due to the through hole 4, and a load transferred from the golf club head 3 to an arm or a shoulder of a human body when a golfer swings the golf club is also reduced. That is, the inventive golf club is suitable for everyone regardless of ages and sexes.

Further, the mesh portion (reference numeral not shown) absorbs a repulsive force of a golf ball due to a reduced-contact area to a golf ball and an elastic force of the wire W, thereby bringing a buffer action.

As a result, since an impulse transferred to a golf ball when hitting a golf ball is reduced due to a reduced weight of the golf club head 3 and a repulsive force is partially absorbed by a buffer action of the mesh portion, a flying distance of a gold ball is reduced.

Preferably, a material of the wire W is selected from one of metal, non-ferrous metal, alloy, elastic fiber, and synthetic resin in consideration of a desired flying distance. Further, a tension is adjusted to achieve a desired flying distance when the wires W are woven with the through hole frame 5.

FIG. 4 is an enlarged view illustrating a cross section of a golf club head according to a second embodiment of the present invention.

A plurality of through holes 4 are initially formed in a golf club head 3 when the golf club head 3 is manufactured. A mesh-shaped lattice portion 6 is formed integrally. As a result, a total weight of the golf club head 3 is significantly reduced, and a flying distance of a golf ball can be adjusted to an appropriate level by a material and a structure of the golf club head 3.

As described above, the inventive golf club achieves a light weight and a short flying distance by a through hole horizontally penetrating a hitting surface of the golf club head and by weaving the wires in a mesh form. As a result, everyone can enjoy golf without taking trouble regardless of ages and sexes even in a relatively small area such as a mini golf course. Also, there is an effect to prevent an injury of like a wrist and an arm joint resulting from an excessive weight of the golf club when hitting a golf ball.

While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention.
