Description

GOLF PUTTER

TECHNICAL FIELD

The present invention relates to a golf putter, and particularly, to a golf putter by which a golfer can strike a ball straight to a target during putting by adhering a guiding member which has similar shape with that of the golf ball on a cavity of a putter head or on rear upper surface of the putter head.

BACKGROUND ART Generally, a putting address in a golf game comprises elements such as a stance, position of a golf ball, grip, distance from the ball, and weight distribution, and an exact stroke can be made through a long experiences in considering of above elements. Actions needed for the exact stroke are as follows. Movement of shoulder can be natural and smooth when a width of the stance in address state is about a width of two putter heads, and weight should be evenly distributed to both soles of feet. However, the weight should be loaded more on heel portions than on toe portions, and it should not be too far or too close from the ball.

An overlapping grip which is a method that a golfer grasps his/her right hand with his/her left second finger is usually used. If a golfer stands his/her wrists too much, the golfer cannot strike the ball regularly and the golfer is likely to strike the behind ground, and his/her pace becomes unstable because of a space at hill portion of the head.

In addition, for a proper putting stroke, a golfer should maintain a pentagonal statute which is formed with both shoulders, both elbows, and grip in address state and swing naturally by rotating the shoulder of the golfer on an axis of his/her spinal column and head as. And a tempo of the putting stroke should be made smoothly, like as, one step is for peak point of back stroke and next step is for impact and follow-through.

In addition, it is desirable for a proper pace that a center line of the head is placed at the center of the ball. The putting stroke should be made so that the ball is moved on putting line by pushing straight the putter as making the putter head, both hands, and both arms a single body, whereby the ball moves to the intended position.

In order to make accurate putting stroke on the green, the golfer should consider above elements, and should experience for a long time in consideration of structural and mechanical relations between the ball and the golfer. It is not easy to make an accurate putting stroke, and one of the important elements which make the putting stoke be difficult is a structural problem, that is, the conventional putter is formed so as not to decide the direction of the ball easily.

Figure 1 is a view showing a stroke by the conventional putter. As shown therein, the conventional golf putter includes a guiding line 120 on central part of a neck face portion 112 on a putter head 110 which is attached to lower end part of a shaft 100, and the golfer strikes a ball 30 along with a visual putting line L (ball to target line) while looking the guiding line 120 on the head.

However, the guiding line 120 for guiding the putting trace is formed shortly on the neck face portion 112 on the conventional putter, and therefore it is difficult to strike the ball as corresponding the putting trace to the putting line L. Accordingly, the stroke is not made in the state that a head face 111 and the ball 30 do not make an accurate square, and thereby a slice or a hook happens.

That is, it is difficult to make an accurate putting stroke with the conventional putter because that the guiding line for aiming the stroke direction of the ball is shortly formed on a small area of the neck face portion even if the golfer exercises for a long time.

TECHNICAL GIST OF THE PRESENT INVENTION

Therefore, an object of the present invention is to provide a golf putter by which the trace of the putting stroke can be corresponded to the putting line in a straight line, and a stroke angle can be easily controlled. Another object of the present invention is to provide a golf putter by which the golfer is able to have better feeling when he/she strikes a golf ball by an effect that a guiding ball adhered on rear side of the putter face directly hits the golf ball.

In order to achieve the objects of the present invention there is provided a golf putter comprising: a putter head including a putter face and a cavity which is extended, as a single body, on rear surface of the putter face; and a guiding member of spherical shape, which is formed on upper surface of the cavity on the head, including a guiding line for guiding the putting trace of the golf ball formed on upper surface.

MODE FOR CARRYING OUT THE PREFERRED EMBODIMENTS The present invention will now be described with reference to accompanying drawings.

There may be many reasons for the difficulties of sending a golf ball to an intended position, one of the reasons is that muscles of a human body are accustomed to pulling rather than pushing. When a person strikes a ball with a certain object, he/she, without repeated exercises, may strike the ball out-to-in. It is considered that solving the out-to-in strike is important when swinging with an iron or a driver, as well as putting.

Famous pro golfers address as locating the putter on front side of the ball. This is for preventing the muscles of left side from pulling to the left side by releasing triceps on right arm, deltoid of right shoulder, and latissimus dorsi flap of right side.

However, the above posture may be changed because of changes in viewing angle, and knee angle, and muscle memory during the address. Therefore, it is difficult to maintain consistent posture.

A ball is attached to rear side of the putter and therefore the golfer feels that the ball strikes the golf ball when putting the golf ball according to the present invention, and therefore a putter face is not pulled in and the putter face is maintained as facing a hole cup for a long time.

According to the present invention, a putting trace can be shown easily by maintaining a center of gravity of the putter on rear side of the putter. Also, a sweet spot which is located on center part of the putter head can be enlarged, and the putter face can direct the hole cup for a long time during the putting by enabling the golfer to feel that the ball on rear side of the putter strikes the golf ball. In addition, the ball on the rear side of the putter makes the addressing be comfortable and easy. The golfer also can get much effects to other swings using an iron or a driver only by exercising putting with the putter of the present invention in a small area. Hereinafter, an embodiment of the present invention will be described with reference to Figures as follows.

Figure 2 is a plan view showing a structure of the putter according to the present invention, and Figure 3 is a perspective view showing the putter of Figure 2 from another angle. As shown therein, the golf putter according to the present invention comprises a guiding member 200 which is attached to a cavity 113 of a head 110, that is, on rear upper surface of a head face 111 , and a guiding line 210 for guiding the putting trace formed on upper side surface of the guiding member 200. An usual golf ball can be used as the guiding member 200, or a spherical matter of similar shape with that of the golf ball and a polyhedron having polygonal section can be used. In addition, it is desirable that the guiding member has same weight as that of the golf ball, however it may have different weight according to weight of the golfer or the shape of the putter. Meanwhile, metal, jade, glass (crystal), plastic, and other jewelry can be used as the material of the guiding member 200, and it is desirable that material of high intensity is used as the guiding member in consideration of impact of the striking.

The guiding member 200 can be attached to the cavity 113 of the putter head 110 in various ways. In case of the metal, it can be attached by soldering the cavity 113. And if a material which can not be soldered is used, a protruded portion may be formed on the cavity 113 and a recesses portion may formed on the guiding member 200, and thereby the protruded portion and the recessed portion 220 are fitted with each other. Figure 4 is showing a coupling state of the guiding member 200 and the putter, the recessed portion 220 formed inside the guiding member 200 is fitted to the protruded portion 221 formed on center of the cavity 113, whereby the guiding member 200 and the putter are coupled. In that case, screw threads may be formed on the protruded portion 221 and on the recessed portion 220 in order to strongly couple the cavity 113 and the guiding member 200.

" '!

In case that the golf ball or similar material is used as the guiding member 200, the guiding line 210 on the upper face of the neck face portion 112 is extended in a straight line on the upper surface of the guiding member 200, and therefore the putting can be made in the state that the putter face and the putting line L make a right angle. Accordingly, the golfer strikes the ball as if he/she hits a ball with another ball in a billiard game, whereby the golfer can easily aim the putting angle.

It is desirable that the guiding line 120 is formed on the neck face portion 112 of the head 110 as in the conventional art, however, it may not be formed if necessary.

In addition, it is desirable that the guiding member 200 of the present invention is located on center of the putter cavity 113, and the height of the guiding member 200 is corresponded to the height of the golf ball which is stricken, even though the height may be changed according to size and shape of the golf putter. Figure 5 shows an example of coupling the guiding member of spherical shape to the putter. As shown therein, a bottom surface of the guiding member 200 is exposed on an lower surface 114 of the cavity 113 so as to have same height as that of the golf ball. Therefore, the golf ball which is stricken and the guiding member 200 have same height as that of each other by corresponding the height of the guiding member to the height of the golf ball lied on the ground, and the center of gravity is corresponded to the center of the ball and the golfer can easily put the golf ball. The height of the guiding member for corresponding to the height of the golf ball may be changed according to the size and the shape of the putter. If a part of the guiding member 200 which is attached to the putter is exposed out of the lower surface 114 of the cavity 113, and guiding member 200 may be contacted to the ground. Therefore, it is desirable that the lower part of the guiding member 200 is not exposed below the lower surface 114 of the cavity 113.

Figure 6 shows that the addressing using the putter according to the present invention in which as a guiding member a ball is used. The golfer 10 judges variables such as a lie of the ball 30 and affects of wind, and after that strikes the ball 30 along with the visual putting line L formed by the ball 30 and the hole cup 20, and the putting trace formed by the guiding line 210 of the guiding member 201 in a straight line or as controlling the angle. At that time, the golfer 10 strikes the ball as if he/she strikes the ball 30 with the guiding member 201. Also, the guiding line 210 is extended on the guiding member 201 , and therefore the putting trace of the putter can be corresponded to the putting line L. Also, the golfer 10 can easily control the striking angle, and accordingly, the golfer 10 is able to send the ball 30 to the hole cup 20 accurately.
