In general, golf clubs are divided into wood, iron, and putter, each of which is divided into various types depending on the distance or angle to be hit.

Among the above golf clubs, the putter is mainly used on the green, and is used for hitting the golf ball and finally putting the golf ball into the hole cup.

The golf putter comprises a putter head for hitting the golf ball and a shaft and grip for connecting to the putter head.

The putter head is formed of a material or body having the same structure as the body and a striking part constituting the striking face. Usually, the body of the putter head is made of aluminum, stainless steel, carbon steel, brass, bronze, titanium, Bronze, titanium, tungsten alloy, copper, polymer and the like.

The outer shape of the putter head is formed by an upper surface, a bottom surface, a front hitting surface, a back surface, a toe, and a heel around the body.

The outline is basically divided into a blade putter, a center shaft putter and a mallet putter.

The blade putter has a lot of weight in the toe direction, and the swing path has an in to in swing path.

In the center shaft putter, the shaft is located at the center of the head, and the swing orbit has a straight track.

The mallet putter has a hammer shape and its weight is evenly distributed throughout the head so that the golf ball can be moved in a consistent direction even if the strike is applied anywhere on the batting surface.

In addition, in the case of a striking face striking a golf ball in a putter head, a loft angle is formed, and a golf ball may be hit or rolled according to the loft angle and the shape formed on the striking face.

5 is a perspective view schematically showing a putter head for golf and a putter for golf according to an embodiment of the present invention. The golf putter according to the present embodiment includes a golf putter head 20, 30, a shaft 70 coupled to a golf putter head, and a grip. Hereinafter, the golf putter head will be described in detail, since the shaft 70 and the grip are the same as or similar to those in the conventional art.

The golf putter head includes an upper head 20 and a lower head 30. The upper head 20 includes an upper face 21 having a convex curved surface. The lower head 30 is located below the upper head 20 and includes a lower face 31 having a convex curved surface. Here, the upper face 21 and the lower face 31 are disposed on the front face of the upper head 20 and the lower head 30, respectively, as a face striking the golf ball 100.

For example, at least one of the upper head 20 and the lower head 30 may be a circular rod.

More specifically, the upper face 21 is a convex curved surface, and may be a circular arc or a portion of an ellipse perpendicular to the extension of the tow and the heel. The lower face 31 may also be a convex curved surface, a circular arc on the cross section perpendicular to the extension line passing through the toe and the heel, or a part of the ellipse. The front face of the upper head 20 is the upper face 21 of the curved face and the front face of the lower head 30 is the lower face 31 of the curved face.

At this time, the upper head 20 and the lower head 30 may be arranged side by side. For example, as shown in FIG. 5, the upper head 20 and the lower head 30 are arranged vertically side by side, and are laid down so as to extend laterally. The center of the upper head 20 and the center of the lower head 30 can be placed in a plane substantially perpendicular to the paper surface 200 or in the acting direction of gravity.

As shown, the upper head 20 and the lower head 30 are each shown to be a circular seal, but are not limited thereto.

6 is a side view schematically showing a side surface of a golf putter head and a golf putter including the golf putter head.

The radius of curvature of the upper face 21 may be less than the radius of curvature of the lower face 31 as shown. Accordingly, the lower face 31 may protrude from the upper face 21 in the traveling direction of the golf ball 100. The effect of this is described in Fig.

Or the curvature radius of the upper face 21 may be equal to the curvature radius of the lower face 31 as shown.

On the other hand, the upper head 20 and the lower head 30 may be manufactured and then joined together by fitting, welding, or the like, or may be joined together by other known methods.

Although the upper head 20 and the lower head 30 may be integrally manufactured, the upper head 20 and the lower head 30 may be separately manufactured and combined. The lower surface 22 of the upper head 20 may be flat and the upper end of the lower head 30 may be flattened to easily connect the upper head 20 and the lower head 30. [ Therefore, the flat lower surface 22 of the upper head 20 and the flat upper surface of the lower head 30 are brought into contact with each other, thereby enabling more accurate and firm coupling.

Referring to FIG. 7, a golf putter head and a golf putter including the golf putter can cut a part of the lower head 30.

Specifically, the lower head 30 can be cut out of the toe portion and the heel portion adjacent to the ground surface 200 at the address. In other words, the lower head 30 can be cut out of the lower side portion 32. At this time, the toe portion and the heel portion of the lower head 30 can be cut into a plane, and can be cut and processed into a gentle and convex curved surface.

Therefore, the golf putter is naturally laid on the green when putting, providing a stable address to the golfer, and providing comfort and psychological stability.

8 is a view schematically showing the operation of a golf putter head and a golf putter including it according to the above-described embodiments.

When the size of the golf ball 100 and the golf putter head are compared, the diameter of the golf ball 100 is 42 mm, and the height of the face surface of the putter is generally lower than the height of the golf ball 100. Then, when the golf ball 100 is puttered with a putter, the face surface of the putter is struck at the center of the golf ball 100. As the putter passes the point of hitting the golf ball 100, .

In consideration of these points, the height of the apex most protruding forward of the upper face 21 of the upper head 20 of the golf putter according to the present invention is preferably set equal to or higher than the height of the center of the golf ball. The height of the vertex protruding forward of the lower face 21 of the lower head 30 of the golf putter of the present invention is set to be lower than the height of the center of the golf ball.

Here, the height is measured based on the golf ball 100 and the ground 200 on which the golf putter head is placed.

In the striking operation, when a vertex protruding forward of the upper face 21 of the upper head 20 at the time of putting first hits an upper end adjacent to the center portion or the central portion of the golf ball 100, ) To roll forward. At this time, a vertex protruding forward of the upper face 21 of the upper head 20 and a vertex protruding forward of the lower face 31 of the lower head 30 may strike the golf ball 100 at the same time.

In another embodiment, the vertex protruding forward of the upper face 21 of the upper head 20 may strike the adjacent lower end of the center of the golf ball 100. [

The lower head 30 hits the golf ball 100 later than the upper head 20 or the upper head 20. In particular, the lower head 30 abuts against the centerline lower portion of the golf ball 100. At this time, the lower head 30 acts to move forward while rolling the golf ball 100 by the upward movement while striking the golf ball 100.

That is, the lower head 30 hits the golf ball 100 by raising the lower portion of the center line so as to smoothly and accurately impart the rotational force to the golf ball 100.

Therefore, when putting into the golf putter according to the present invention, the upper head 20 primarily advances forward while rolling the golf ball 100 while striking the golf ball 100, Increases the rolling and forward motion of the golf ball 100 while striking the golf ball 100 again.

As described above, by using the golf putter according to the present invention, the straightness of the golf ball 100 during putting can be remarkably improved.

The golf putter head and the golf putter including the golf putter head according to the present embodiment are substantially the same as or similar to the golf putter head and the golf putter including the golf putter head according to the above embodiment except for the parts to be described later.

Therefore, redundant description will be omitted below, and the changed portions will be mainly described. The same is true for the other embodiments.

According to the present embodiment, the center of gravity of the putter head for golf can be located in the lower head 30. For example, the lower head 30 may be made of a material that is heavier than the upper head 20, or may be made bulky even if the materials are the same.

Or the inside of the upper head 20 may be manufactured to be empty, or the center of gravity may be placed on the lower head 30 by attaching a heavy metal such as lead to the lower head 30. [

As another example, as shown, the golf putter may further include a rear head 40 disposed in parallel with the lower head 30 at a lower portion of the upper head. That is, the golf putter may include two round bars at the bottom. In this case, the radius of curvature of the upper face may be greater than or equal to the radius of curvature of the lower face. At this time, the lower head 30 and the rear head 40 may be horizontally disposed on the ground surface 200 at the address.

The lower head 30 and the rear head 40 may be smaller in diameter than the upper head 20. However, the present invention is not limited thereto, and in some cases, the diameter of each head can be variously changed.

Further, the lower head 30 may protrude forward from the upper head 20. That is, the center of the lower head 30 may be located apart from the center of the upper head 20 in the traveling direction of the golf ball 100.

The sum of the weights of the lower head 30 and the rear head 40 may be heavier than the upper head 20. [ In other words, the center of gravity may be located in or between the bottom head 30 and the rear head 40.

More specifically, the center of gravity of the combination of the center of gravity of the lower head 30 and the center of gravity of the rear head 40 is located on the line perpendicular to the ground 200 and the center of gravity of the upper head 20, can do.

In other words, the overall shape of the golf putter head is made up of three circular rods as shown. And are placed side by side in two circular rods of about the same size, with one circular rod having a larger diameter disposed thereon.

At this time, the lower head 20, the rear head 40, and the upper head 20 may be combined or integrally formed by welding, adhesive, or the like.

Of course, the shape of the golf putter head is not limited thereto, and various modifications are possible so that the center of gravity is positioned below the center of gravity of the upper head.

Therefore, stable putting is possible because the center of gravity is located in the lower head 30. [

Referring to FIG. 10 (b), the lower head 30 may be in the form of a mallet putter head. Specifically, the lower head 30 may have a flat bar shape having a lower face 31 on its front surface.

In particular, the bottom surface of the lower head 30 may be a flat surface or a gently curved surface. In addition, the rear surface of the lower head 30 may be curved like a front surface. Of course, the shape of the lower head 30 is not limited thereto.

At this time, the weight of the lower face 31 is greater than the weight of the upper face 21, and the center of gravity of the golf putter head is located in the lower face 31.

Therefore, the lower surface of the lower head 30 is formed as a flat surface or a gentle curved surface, so that it can be easily manufactured. In addition, since the center of gravity is located in the lower head 30, the golfer can put more stably.

Referring to FIG. 10 (c), the lower head 30 may further include an extension 50 extending to the opposite side of the lower face 31. Wherein the extension 50 extends from the lower surface of the lower head 30. In particular, the upper surface of the extension 50 may be recessed or angled as shown.

That is, as shown in the drawing, the extension portion 50 may have a shape gradually decreasing rearward. At this time, the tip 51 of the extended portion 50 can be bent upward to easily lift the golf ball 100 from the green.

Accordingly, not only the golfer can easily hold the golf ball 100, but also stable putting is possible from the shape of the lower head 30.
