5 is a perspective view schematically showing a golf putter head and a golf putter including the same according to an embodiment of the present invention. Golf putter according to this embodiment includes a golf putter head 20, 30 to be described later, a shaft 70 and a grip coupled to the golf putter head. Hereinafter, the shaft 70 and the grip are the same as or similar to the conventional one, so the golf putter head will be described in detail below.

Golf putter head according to an embodiment of the present invention includes an upper head 20 and the lower head 30. The upper head 20 includes an upper face 21 made of a convex curved surface. The lower head 30 is positioned below the upper head 20 and includes a lower face 31 formed of a convex curved surface.

Here, the upper face 21 and the lower face 31 are surfaces that strike the golf ball 100, and are disposed in front of the upper head 20 and the lower head 30, respectively. At least one of the upper head 20 and the lower head 30 may be formed of, for example, a circular rod.

In more detail, the upper face 21 is a convex curved surface, and may be an arc shape or a part of an ellipse in cross section perpendicular to the extension line passing through the tow and the heel. In addition, the lower face 31 is a convex curved surface, and may be an arc shape or a part of an ellipse on a cross section perpendicular to the extension line passing through the tow and the heel. Accordingly, the front face of the upper head 20 is the curved upper face 21, and the front face of the lower head 30 is the curved lower face 31.

In this case, 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 side by side up and down, and are laid down to extend left and right. Therefore, the center of the upper head 20 and the center of the lower head 30 may lie in a plane perpendicular to the ground 200 or in the direction of gravity's action. As shown, the upper head 20 and the lower head 30 are each shown as being a circular rod, but is not limited thereto.

6 is a side view schematically showing a side of a golf putter head and a golf putter including the same. In the embodiment of FIG. 6, the radius of curvature of the upper face 21 may be smaller than the radius of curvature of the lower face 31 as shown. Therefore, the lower face 31 may protrude more than the upper face 21 in the advancing direction of the golf ball 100. The effect on this is described in FIG. 8. Alternatively, the radius of curvature of the upper face 21 may be equal to the radius of curvature of the lower face 31, as shown.

Meanwhile, the upper head 20 and the lower head 30 may be manufactured and then joined by fitting, welding, or the like, or may be joined by other known methods. In addition, the upper head 20 and the lower head 30 may be manufactured integrally, but the upper head 20 and the lower head 30 may be separately manufactured and combined. In this case, in order to easily couple the upper head 20 and the lower head 30, the lower surface 22 of the upper head 20 may be flat, and the upper end of the lower head 30 may be flat. Therefore, the flat lower surface 22 of the upper head 20 and the flat upper surface of the lower head 30 may be brought into contact with each other, thereby making it possible to more accurately and firmly combine them.

Referring to FIG. 7, a golf putter head and a golf putter including the same may be cut off a portion of the lower head 30.

In detail, the lower head 30 may have a tow portion and a heel portion that are adjacent to the ground 200 when being addressed. That is, the lower head 30 may be cut both sides 32. At this time, the tow portion and the heel portion of the lower head 30 may be cut to a plane, or may be cut to a gentle and convex curved surface. Therefore, the golf putter is naturally placed on the green when putting, providing a stable address to the golfer, providing comfort and psychological stability.

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

When comparing the size of the golf ball 100 and the golf putter head, the diameter of the golf ball 100 is substantially 42mm, the height of the face surface of the putter is generally lower than the height of the golf ball 100. And, when putting the golf ball 100 with a putter, the face of the putter is hit to the center of the golf ball 100, the putter head is the upward movement while passing the point where the putter hit the golf ball 100 Done. In view of these points, it is preferable that the height of the peak most protruding forward of the upper face 21 of the upper head 20 of the golf putter according to the present invention is set equal to or higher than the height of the center of the golf ball. Then, the height of the apex protruding forward of the lower face 21 of the lower head 30 of the golf putter of the present invention is set 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 putter head for golf is placed.

Next, the hitting operation will be described with reference to FIG. 8.

In general, when putting a golf putter is a golf ball placed under the left eye. When putting in this conventional manner, the apex protruding forward of the upper face 21 of the upper head 20 first strikes the center or upper end adjacent to the center of the golf ball 100 and then ascends. Advance forward while rolling golf ball (100). At this time, the vertex protruding forward of the upper face 21 of the upper head 20 and the vertex protruding forward of the lower face 31 of the lower head 30 may hit the golf ball 100 at the same time.

On the other hand, when putting using a golf putter according to an embodiment of the present invention, according to the position of the golf ball, a new effect can be obtained. For example, when the golf ball is placed under the right eye, the putter protrudes forward of the upper face 21 of the upper head 20 of the putter and the lower face 31 of the lower head 30. Since the vertices protruding toward the front of the golf ball can hit the top and bottom of the center of the golf ball at the same time or continuously, the straightness (rolling) can be improved. In addition, when the golf ball is near the green edge, the chipping function is possible by putting the golf ball on the left foot. That is, since the golf ball is on the left foot side, the lower head 30 of the putter raises the golf ball slightly below the chipping, thereby enabling chipping near the edge.

Further, in other embodiments, a vertex projecting forward of the upper face 21 of the upper head 20 may strike an adjacent lower end of the center of the golf ball 100. The lower head 30 strikes the golf ball 100 simultaneously with the upper head 20 or later than the upper head 20. In particular, the lower head 30 contacts and strikes a portion below the center line of the golf ball 100. At this time, the lower head 30 serves to move forward while rolling the golf ball 100 by the upward movement while hitting the golf ball 100. That is, the lower head 30 hits the golf ball 100 while raising the lower portion of the center line, giving the golf ball 100 a smoother and more accurate rotational force. Therefore, when putting into the golf putter according to the present invention, the upper head 20 is first to move forward while rolling the golf ball 100 while hitting the golf ball 100, the second lower head 30 A) increases the rolling motion and the straight forward movement of the golf ball 100 while hitting the golf ball 100 again. As such, when the golf putter according to the present invention is used, the straightness of the golf ball 100 can be remarkably improved when putting.

Figure 9 is a perspective view schematically showing a golf putter head and a golf putter including the same according to another embodiment of the present invention, Figure 10 (a) is a golf putter head and the same It is a side view of a golf putter.
