Description

  The present invention relates to a golf putter head.

  Various improvements have been made to putter head structures used in golf, and various structures have been proposed.

  The performance required for a golf putter is that the control of the direction of travel of the ball and the feeling of travel distance of the ball can be easily obtained.

  In order to obtain such performance, the structure shown in FIGS. 1A and 1B is used as a general putter head structure.

  1A and 1B respectively show a front view and a side view of the putter head viewed from the golf ball 3 side.

  The main body 1 of the putter head has a front face surface (see FIGS. 1B and 1C) that comes into contact with the golf ball 3 when the ball is launched (putting).

  A shaft 2 having a predetermined length is connected to the main body portion 1 of the putter head, and a grip portion is provided on the upper tip side of the shaft 2 (not shown).

  In FIG. 1A, the body part 1 of the putter head is defined by a toe 1A on the side opposite to the position where the golfer stands and a heel 1B on the golfer side, a lateral width W extending from the toe 1A to the heel 1B, and a top 1D. It has a height H behind the sole 1E.

  Further, it has a predetermined thickness on the side opposite to the front face surface 1C.

  And the main-body part 1 of a putter head is shape | molded with metal materials, such as a brass, iron, and stainless steel.

  With respect to such a putter head, improvement has so far been promoted mainly from the viewpoint of the accuracy of the rolling direction and movement distance of a golf ball. That is, various proposals have been made regarding the shape, angle, front face surface shape, etc. of the sole to enable a smooth back swing during the putting operation and to give a favorable rotation to the smooth golf ball at the time of impact. (For example, Patent Documents 1 and 2).

  Here, as described above, until now, the improvement has been made exclusively from the viewpoint of the accuracy of the rolling direction and the moving distance of the golf ball, but even the improved putter head has the characteristics of the putter head. If the putting is not performed, the accuracy of the rolling direction and the moving distance cannot be obtained.

  On the other hand, it is not easy for an amateur golfer to acquire the characteristics of such a putter head and always perform a putting operation suitable for the characteristics. That is, even if favorable putting is performed, even if the putting result is not preferable, it is recognized how such a putting result is obtained in relation to the characteristics of the putter head, or It is not easy to learn.

  As a result, there is a problem that the putting operation is not stable, and the contribution of the score increase by putting is reduced.

  Accordingly, an object of the present invention is to provide a golf putter head that can increase the concentration of a golfer during a putting operation and can more clearly understand the relationship between the putting result and the putting operation.

The golf putter head according to the present invention that achieves the above object is

  Embodiments of the present invention will be described below with reference to the drawings. The embodiments are for understanding the present invention, and the scope of protection of the present invention is not limited to the embodiments.

  2A is a front view of a putter head according to an embodiment of the present invention as viewed from the golf ball side, and FIG. 2B is a side view of the putter head according to the embodiment of the present invention corresponding to FIG. 2A.

  2A and 2B, the putter head is composed of a main body part 11, a weight balance part 10 provided on the upper side thereof, and a link part 12 connecting them.

  The main body 11 and the weight balance 10 are connected by spot welding 13 or the like depending on the material of the head used.

  One end of the shaft 2 having an appropriate length is connected to the upper surface side of the weight balance portion 10 to form a golf putter.

As a feature of the present invention, the front face surface of the main body 11 that contacts the golf ball 3 is equal to or smaller than the area corresponding to the diameter of the cross section of the central portion of the golf ball. It is the area to do. Therefore, preferably, it has an area of the front face surface of 15cm ² ~0.7cm ^2.

  The following table summarizes the approximate specifications of commercially available golf putters for comparison with the present invention.

  In the above table, the head dimension is obtained by width * height * adjustment coefficient, and the adjustment coefficient is a coefficient value considering that the toe and the heel part are rounded.

The average value of the front face area of a general putter head obtained from the above table is 25.8 cm ² .

On the other hand, the present invention substantially corresponds to the size of the center diameter of the pachinko ball from the size of the center diameter of the golf ball when the average diameter size of the center portion of the golf ball is 4 cm. range of the area 15cm ² ~0.7cm ^2, the front face area of the main body portion 11.

The area of the main body 11 in the present invention is characterized in that it is set smaller than the average front face area of 25.8 cm ² of the head of the general putter shown in the above table.

  As described above, by setting the front face area of the main body 11 of the putter head to be small, the golfer is required to increase the concentration by the launch direction and launch speed of the goal when putting.

  Thereby, the golfer can grasp the relationship between the putting result and the putting operation performed by the golfer more clearly, and it is easy to lead to improvement of the putting operation.

  Here, in the embodiment shown in FIGS. 2A and 2B, the main body 11 has a substantially bullet-like shape. However, the present invention is not limited to such a shape.

  3A and 3B are views showing the form of a putter head according to another embodiment. In this embodiment, the main body portion 11 is formed integrally with the link portion 12 in the embodiment shown in FIGS. 2A and 2B.

  That is, the main body portion 11 is configured to use a member having a thickness larger than that of the first embodiment and to be connected to the weight balance portion 10 on the back surface side with respect to the front face surface.

  Further, in the present invention, in the above embodiment, the shape of the front face surface of the main body 11 is shown as having a circular shape, but the shape is not limited to such a shape. That is, an arbitrary polygonal shape can be used as long as the above requirement for having a small front face area is satisfied.

  Here, as a golf putter, it is desirable that the putter head has a corresponding weight in order to absorb a smooth swing flow at the time of backswing and an impact at the time of impact.

  Therefore, the average putter head weight is required to be 290 g from the above table.

  As described above, the putter head of the present invention has a front face area smaller than that of the conventional putter head, and therefore the size of the main body 11 is inevitably small and its weight is also small.

  In such a case, the main body 11 alone cannot absorb the smooth swing flow during the back swing and the impact during the impact as a golf putter.

  For this purpose, the present invention has a weight balance portion 10 at the upper portion of the main body portion 11. Based on the weight of the main body 11, the weight of the weight balance 10 is selected and set so as to be an average putter head weight, for example, about 290 g.

  Further, the shape of the weight balance 10 having such a selected and set weight is devised so as to have a corresponding weight.

  For example, when the main body 11 is made of brass, it is preferably formed using stainless steel having a larger specific gravity.

  FIG. 4A, FIG. 4B, and FIG. 5 are figures which show the form of the putter head produced by forming the weight balance 10 in the shape of a dragonfly as a specific shape as an example.

  FIG. 4A is a perspective view of a putter head according to an embodiment of the present invention as viewed from the golf ball side. 4B is a perspective view of the example putter head corresponding to FIG. 4A as viewed from the side opposite to the golf ball. FIG. 5 is a side view of the embodiment corresponding to FIG. 4A.

  As shown in FIG. 4A, a weight balance portion 10 having an end surface that is recessed from the front face surface is provided on the upper portion of the main body portion 11 having a circular front face surface, as shown in FIGS. 4A, 4B, and 4C. ing.

  In the embodiment shown in FIGS. 4A, 4B, and 5, the planar form of the weight balance 10 is imitated as a register mark, but the present invention is not limited to such form.

  For example, a flat pattern imitating a flying object such as a butterfly, a bird or an airplane with its wings spread may be used. The planar pattern can be easily cut out from, for example, a stainless plate using a laser processing machine.

  Thus, by using various patterns for the weight balance unit 10, it is possible to provide a golf putter that suits the golfer's preference.

  As described above, the present invention can be easily made of any material such as brass, iron, and stainless steel with the main body portion and the weight balance portion as main components, and thus can be widely provided to many amateur golfers. Therefore, the present invention greatly contributes to the industry.
