Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a putter used when putting on the green of a golf course.

[0002]

[Prior art]

 In recent years, golf has become more and more popular, and along with this, golf clubs have been improved in shape, structure, and material from woods, irons to putters. In particular, in putters that putt toward the cup on the green of the golf course, the shape of the putter head is diverse, and the bending shape of the shaft at the joint with the putter head is also changed to suit the user's preference. I am ready to respond.

By the way, the putter shaft is generally made of steel, and other graphite and carbon fiber are becoming popular. In any case, the shape of the putter shaft is a circular pipe, and the tip portion of the circular pipe is A putter head of different shape and structure is replaceably attached, and a grip is provided at the base end.

In order to perform more accurate putting, the face surface of the putter head is held at a right angle with respect to the putting line that connects the ball and the cup, take back, and then return to the impact position completely for putting. There is a need.

[0005]

[Problems to be solved by the device]

 However, since the conventional putter shaft is a circular pipe, it is difficult to hold the face surface of the putter head at a right angle with respect to the putt line, and the putter head may shake even at a short distance from the takeback to the impact. is there.

That is, since the conventional putter shaft is a circular pipe, the target (putt line) is caught at a point, and it is extremely difficult to take back in parallel to the putt line, return to the impact position, and swing. As a result, the probability that a putt will enter is low.

The present invention has been made in view of the above circumstances, and its purpose is to be able to catch the target (put line) on the surface during putting, and to putter head from take back to impact. The goal is to provide a putter that swings parallel to the putt line, can hit the ball accurately, and has a high probability of putting a putt.

[0008]

[Means and Actions for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is a putter having a putter head at the tip end of a putter shaft and a grip at the base end, wherein the putter shaft is formed into a square pole and the face of the putter head is formed. The shaft side surface parallel to the plane is defined as a reference plane, and the shaft side surface perpendicular to the reference plane is perpendicular to the face surface of the putter head.

When the putter shaft is formed in a quadrangular prism, and the shaft side surface parallel to the face surface of the putter head is used as a reference surface, the shaft side surface perpendicular to the reference surface is perpendicular to the face surface of the putter head. By swinging this surface in parallel with the putt line, the putter head can put the ball on the putt line.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall view and a cross-sectional view of a putter. Reference numeral 1 is a putter shaft. A putter head 2 is provided at the tip of the putter shaft 1 and a grip 3 is provided at the base end of the putter shaft 1. .

As shown in FIG. 2, the putter shaft 1 is made of, for example, carbon fiber, and the shaft main body 4 has a square cross section and is formed into a hollow quadrangular prism. Further, the shaft main body 4 is formed so as to gradually become thinner from the base end side toward the tip end side.

Further, the base end portion of the putter shaft 1 is formed into a cylindrical portion 5 on which the grip 3 is mounted, and the boundary portion between the cylindrical portion 5 and the quadrangular prism shaft main portion 4 has a sharp cross-sectional area. The arcuate surface 6 is formed to reduce the change.

As shown in FIG. 3, a quadrangular hole 7 is provided at the tip of the shaft main body 4, and the base end of the shaft portion 8 of the putter head 2 is inserted into the quadrangular hole 7. It is fixed by the adhesive. The shaft portion 8 of the putter head 2 is also formed in a quadrangular prism like the shaft main body portion 4, and the first shaft side surface 9a of the shaft main body portion 4 including the shaft portion 8 is the face surface 2a of the putter head 2. The second shaft side surface 9b which is parallel and is perpendicular to the first shaft side surface 9a is formed at a right angle to the face surface 2a.

Therefore, as shown in FIG. 4, at the time of putting, the spot 10 of the putter head 2 is aligned with the center of the ball 11 and the second shaft side surface 9 b is aligned parallel to the put line 12. The face surface 2 a of the putter head 2 can be held at a right angle to the pad line 12.

Therefore, by putting back the putter head 2 along the put line 12, returning it to the impact position as it is, and hitting the ball 11, the ball 11 can be rolled along the put line 12, The putter head 2 does not shake from the takeback to the impact, and the ball 11 can be hit accurately by swinging in parallel with the put line 12.

Here, it is important to note that the shaft main portion 4 of the putter shaft 1 and the shaft portion 8 of the putter head 2 are formed in a square pole, and the first shaft side surface 9a, that is, the reference surface, is the putter head 2. The second shaft side surface 9b that is parallel to the face surface 2a and is perpendicular to the first shaft side surface 9a (reference surface) is formed at a right angle to the face surface 2a.

Therefore, by arranging the second shaft side surface 9b in parallel with the putt line 12 (square), the face surface 2a of the putter head 2 is inevitably perpendicular to the putt line 12, and from the stance to the address. It is smooth and can be putted in a series of flows. As a result, the probability that a putt will enter is further increased, which has the effect of increasing the score.

Further, since the putter shaft 1 is made of carbon fiber, the weight of the shaft can be reduced and the moment of inertia of the putter head 2 can be increased. Putting is possible.

Although the shaft portion 8 of the putter head 2 is provided at one end of the putter head 2 in the above-described embodiment, the shape and structure of the putter head 2 are limited to the embodiment. Further, the shaft portion 8 of the putter head 2 may be biased to the face surface 2a side or the back portion side of the putter head 2, and can be replaced appropriately according to the preference of the user.

The putter shaft 1 is not limited to carbon fiber, and may be steel or graphite. The shaft main body 4 is formed in a square pole, and the second shaft side surface 9 b is set parallel to the put line 12. Thus, the face surface 2a of the putter head 2 is inevitably perpendicular to the putt line 12.

[0021]

[Effect of device]

 As described above, according to the present invention, the putter shaft is formed in the shape of a quadrangular prism, the shaft side surface parallel to the face surface of the putter head is used as the reference surface, and the shaft side surface perpendicular to the reference surface is used as the putter head. The feature is that it is perpendicular to the face surface. Thus, by aligning the shaft side surface, which is perpendicular to the shaft side surface parallel to the face surface of the putter head, with the put line in parallel, the face surface of the putter head can be held at a right angle to the put line.

Therefore, by putting back the putter head along the put line, returning it to the impact position as it is, and hitting the ball, the ball can be rolled along the put line, and the putter head can be moved from the take back to the impact. You can hit the ball accurately by swinging parallel to the put line without shaking.

Moreover, by arranging the shaft side surface parallel to the putt line, the face surface of the putter head is inevitably perpendicular to the putt line, and the stance to the address are smooth, and in a series of flows. You can putt. As a result, the probability of putting a pad is further increased, which has the effect of increasing the score.
