Description

The present invention relates to a putter head for golf (hereinafter, may be simply referred to as a "head") and a putter having a shaft attached to the head.

Various types of golf putters have been developed so far, and the main development policy is to accurately control the direction in which the golf ball (hereinafter, also referred to simply as "ball") is rolled. It is to realize a putter that can be played. Some of them have an improved connection structure between the head and the shaft, and for example, the ones shown below have been devised.

Japanese Unexamined Patent Publication No. 9-38247 Japanese Unexamined Patent Publication No. 2002-224252

In Patent Document 1, a hosel is attached to the end of the head, and the center of the socket portion provided at the end of the hosel into which the shaft is inserted is a surface of a golf ball rather than a face surface on which the ball is hit. A golf putter that protrudes by a distance of 1/2 of the diameter is disclosed.

Patent Document 2 discloses a golf putter connected to the position of the center of gravity of the head by bending the tip of the shaft from the opposite face surface of the head.

In the case of the golf putter of Patent Document 1, since the hosel is attached to one end of the head, when hitting the ball, the direction orthogonal to the face surface passing through the center of gravity of the head may deviate from the center of the ball. Alternatively, the face surface may be tilted in the circumferential direction of the shaft, and the ball may roll in a direction contrary to the intention of the user.

In the case of the golf putter of Patent Document 2, it is said that the target can be caught on the extension of the horizontal straight portion of the shaft connected to the opposite face surface side, but when the user hits the ball, the target is caught. Since the golf putter must be swung so that the center of the ball coincides on the extension while assuming the extension of the horizontal straight portion of the shaft, the head is similar to the golf putter of Patent Document 1. There is still the possibility that the direction orthogonal to the face surface passing through the center of gravity of the ball will deviate from the center of the ball.

Therefore, in view of the above-mentioned circumstances, the present invention makes it easy to match the direction of the line passing through the center of gravity of the head with the center of the ball, which is orthogonal to the face surface at the time of hitting, and can accurately control the direction in which the ball is rolled. The purpose is to provide a head and a putter equipped with the head.

The present invention comprises a head having an upper side and a bottom side and having a face surface for hitting a golf ball.
A first hosel portion attached to the opposite side of the face surface of the head so as to pass through the center of gravity of the head and extending from the bottom side toward the upper side.
It is connected to the first hosel portion, extends in the same direction as the line orthogonal to the face surface and passing through the center of gravity, and extends from the bottom to a position higher than the diameter of the golf ball on the face surface side. The second hosel part with an extension part and
A putter head connected to the extension portion and having a socket portion where an extension line of the axis intersects with a position on the line at a distance equal to the radius of the golf ball from the face surface. ,
Or,
The above-mentioned problem is solved by a putter in which a shaft is attached to a socket portion of the putter head.

According to the present invention, first, since the first hosel portion is attached to the head on the opposite side of the face surface so as to pass through the center of gravity of the head, when the putter equipped with the head is shaken. Contrary to the user's will, the face surface is unlikely to tilt in the circumferential direction of the shaft. Further, a second hosel portion having an extending portion orthogonal to the face surface, extending in the same direction as the line passing through the center of gravity of the head, and extending from the bottom to a position higher than the diameter of the golf ball on the face surface side. Since the second hosel part can be overlapped with the ball until the ball hits the face surface, the user can use the ball in the direction in which the second hosel part extends until the moment when the ball is hit on the face surface. Can be grasped as the rolling direction. Further, the socket portion to which the shaft is connected is connected to the extending portion of the second hosel portion, and the axis line thereof is orthogonal to the face surface and passes through the center of gravity of the head. Since it intersects with a point at the same distance as the radius, by overlapping the ball with the second hosel part and overlapping the ball on the extension line of the shaft, the center of gravity of the head and the ball can be directed in the direction in which the ball is desired to be rolled. The position of the center can be easily adjusted. Therefore, the head and putter can easily match the positions of the center of the ball and the center of gravity of the head at the time of hitting, and can accurately control the rolling direction of the ball.

Further, if the center of gravity of the head is located at the same distance as the radius of the golf ball from the bottom of the head, it is preferable because the center of gravity of the head and the center of the ball can be easily aligned in the vertical direction at the time of hitting. Is.

Further, if the socket portion is configured to be inclined with respect to the second hosel portion, the user assumes two lines having different angles, that is, the extension direction of the second hosel portion and the extension line of the center of gravity of the socket portion. Therefore, it is possible to make it easier to align the position of the center of gravity of the head with the center of the ball.

Further, the first hosel portion is connected to the head via a third hosel portion that is orthogonal to the face surface and extends in the same direction as the line passing through the center of gravity of the head, and the mounting angle of the third hosel portion to the head is variable. If there is a configuration in which the mounting angle of the second hosel portion with respect to the third hosel portion is variable, the user can arbitrarily determine the direction of the socket portion, that is, the optimum angle of the shaft.

Examples of the present invention will be described with reference to FIGS. 1 to 5. However, the present invention is not limited to this embodiment.

FIG. 1 shows a putter 10 having the putter head 12 of the present invention. The putter 10 is mainly composed of a head 12, a hosel 20, and a shaft 32. Although not shown, a grip is attached to the shaft 32. The head 12 includes a face surface 14 (see FIG. 2) having an upper side 16 and a bottom side 18 for hitting a golf ball B. The dimensions from the top side 16 to the bottom side 18 and the shape of the face surface 14 are arbitrarily determined. Further, although the head 12 shown in the figure is a pin type and has weights 13 at both ends, the present invention can be applied to other types of heads such as a caching type and a blade type.

In the case of the putter 10, the hosel 20 connecting the head 12 and the shaft 32 is interposed between the first hosel portion 22, the second hosel portion 24, the socket portion 26, and the second hosel portion 24 and the socket portion 26. It is composed of a connecting member 27. The first hosel portion 22 extends from the face surface 14 (see FIG. 2) of the head 12 so as to extend from the bottom 18 toward the top 16, and more specifically, vertically when the bottom 18 is grounded. It is installed on the opposite side. Further, as shown in FIGS. 1 and 2, the first hosel portion 22 is configured to pass through the center of gravity G of the head 12. With this configuration, it is possible to prevent the face surface 14 from tilting in the circumferential direction of the shaft 32 against the will of the user when the putter 10 is shaken. It should be noted that the center of the first hosel portion 22 is configured to be located on the vertical plane of the line Y (the plane corresponding to the 2-2 line in FIG. 1) which is orthogonal to the face surface 14 and passes through the center of gravity G of the head 12. Therefore, it is possible to further prevent the shaft 32 of the face surface 14 from being tilted in the circumferential direction.

The second hosel portion 24 is attached to the upper end of the first hosel portion 22, and as shown in FIG. 2, is orthogonal to the face surface 14 and extends in the same direction as the line Y passing through the center of gravity G of the head 12. When the face surface 14 is provided with a slight inclination (loft), the line Y may be determined assuming the face surface 14 perpendicular to the installation surface. Further, the second hosel portion 24 is on the face surface 14 side, that is, on the side opposite to the side where the first hosel portion 22 exists with respect to the face surface 14, and is the diameter of the golf ball B from the bottom 18 (golf ball standard). However, in the figure, it is provided with an extension portion 25 extending to a position higher than 2r.) As a result, the user of the putter 10 can overlap the second hosel portion 24 with the ball B until the ball B hits the face surface 14, so that the second hosel portion 24 can be overlapped with the ball B until the moment when the ball B is hit by the face surface 14. (2) The direction in which the hosel portion 24 extends can be grasped as the direction in which the ball B rolls. Further, as shown in the figure, the first hosel portion 22 includes a protruding portion 23 protruding from the upper side 16 of the head 14, and the second hosel portion 24 has a diameter of the golf ball B from the bottom 18 of the protruding portion 23. If the structure is connected so as to be horizontal at a higher position, interference between the second hosel portion 24 and the ball B can be reliably prevented. On the other hand, the upper surface of the second hosel portion 24 can be painted with an easily visible paint.

In the socket portion 26, the extension line X of the axis of the socket portion 26 is orthogonal to the face surface 14 and passes through the center of gravity G of the head 12, and the same distance as the radius r of the ball B is provided from the face surface 14 on the line Y. It is connected to the extending portion 25 of the second hosel portion 24 via the connecting member 27 so as to intersect with the point C (see also FIG. 1). Further, since the axis of the socket portion 26 and the axis of the shaft 32 are configured to coincide with each other, the second hosel portion 24 and the ball B are overlapped with each other, and the ball B is overlapped on the extension line of the shaft 32. , The position of the center of gravity G of the head 12 and the position of the center of the ball B (the same position as C) can be easily aligned with the direction in which the ball B is desired to be rolled.

As shown in the figure, the center of gravity G of the head 12 is preferably located at the same distance as the radius r of the golf ball B from the bottom surface 18 of the head 12. According to this configuration, when the ball B is hit by the putter 10, the center of gravity G of the head 12 and the center of the ball B can be easily aligned in the vertical direction, so that the force from the putter 10 can be easily transmitted to the ball B.

As shown in FIG. 1, the socket portion 26 can be configured to be inclined with respect to the second hosel portion 24. With this configuration, the user can assume two lines having different angles, that is, the extension direction of the second hosel portion 24 and the extension line X of the axis of the socket portion 26, so that the center of gravity G of the head 12 and the ball B can be assumed. It is possible to make it easier to align the position of the center of. The tilting direction of the socket portion 26 is arbitrary, but as shown in the figure, when the second hosel portion 24 is tilted laterally with respect to the stretching direction, the user can see his / her own line of sight, the shaft 32, and the shaft 32. It is easy to align with the axis of the socket portion 26.

3 and 4 show putters 10a and 10b of another embodiment of the present invention. Since the basic configuration of the putters 10a and 10b is the same as that of the putter 10, the description of the overlapping portion will be omitted. In the putter 10a shown in FIG. 3, the first hosel portion 22 is connected to the head 12a via a third hosel portion 28 that is orthogonal to the face surface 14 and extends in the same direction as the line Y passing through the center of gravity G of the head 12. There is. Further, although detailed illustration is omitted, since the third hosel portion 28 is fixed to the opposite side of the face surface 14 with screws, the mounting angle of the third hosel portion 28 with respect to the head 12a is variable. According to this configuration, the user can arbitrarily determine the direction of the socket portion 26, that is, the optimum angle of the shaft 32.

Further, as in the putter 10b shown in FIG. 4, the position of the first hosel portion 22 is fixed by rotatably fitting the first hosel portion 22 to the third hosel portion 28a and tightening with the screw 29. As a configuration, the user can arbitrarily determine the optimum angle of the shaft 32. Further, as shown in the figure, the socket portion 26 may be directly attached to the second hosel portion 24, or may be located ahead of the second hosel portion 24 in the extending direction.

Further, as in the putter 10c shown in FIG. 5, the first hosel portion 22 may be tilted and attached to the head 12. In short, the first hosel portion 22 may pass through the center of gravity G of the head 12.

As described above, according to the present invention, at the time of hitting, it is easy to match the direction of the line orthogonal to the face surface and passing through the center of gravity of the head with the center of the ball, and the head capable of accurately controlling the direction in which the ball is rolled. And can provide a putter with this.
