Description

  The present invention relates to a putter head for golf (hereinafter sometimes simply referred to as “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 of rolling a golf ball (hereinafter sometimes simply referred to as “ball”). It is to realize a putter that can. Some of them have improved the connection structure between the head and the shaft. For example, the following structure has been devised.

Japanese Patent Laid-Open No. 9-38247 JP 2002-224252 A

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

  Patent Document 2 discloses a golf putter in which the tip end of a shaft is bent and connected to the center of gravity of the head from the opposite face surface of the head.

  In the case of the golf putter of Patent Document 1, since the hosel is configured to be 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 inclined in the circumferential direction of the shaft, and the ball may roll in a direction contrary to the user's will.

  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 linear portion of the shaft connected to the anti-face surface side, but when the user hits the ball Since the golf putter must be shaken so that the center of the ball coincides with the extension while assuming the extension of the linear portion of the shaft in the horizontal direction, like the golf putter of Patent Document 1, There is still a possibility that the direction perpendicular 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 circumstances described above, the present invention makes it easy to match the direction of a line perpendicular to the face surface and passing through the center of gravity of the head and the center of the ball at the time of hitting, and to accurately control the direction of rolling the ball. It is an object to provide a head and a putter having the head.

The present invention comprises a head having a face surface for hitting a golf ball having an upper side and a bottom side;
A first hosel part 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;
Connected to the first hosel part, extending in the same direction as a line perpendicular to the face surface and passing through the center of gravity, extending from the bottom side to a position higher than the diameter of the golf ball. A second hosel part having an extension part;
A putter head comprising a socket portion connected to the extension portion and having an extension line of an axial center intersecting with a position on the line at the same distance as the radius of the golf ball from the face surface. ,
Or
The problem has been solved by a putter in which a shaft is attached to the socket portion of the putter head.

  According to the present invention, first, the first hosel part is attached to the head on the opposite side of the face surface and through the center of gravity of the head, so when the putter including the head is shaken Contrary to the user's will, the face surface is difficult to tilt in the circumferential direction of the shaft. Also, a second hosel part having an extending part that is orthogonal to the face surface, extends in the same direction as a line passing through the center of gravity of the head, and extends from the bottom surface to a position higher than the diameter of the golf ball. Since the second hosel part can overlap the ball until the ball hits the face surface, the user can set the direction in which the second hosel part extends until the moment the ball is hit on the face surface. Can be grasped as the direction of rolling. Further, the socket portion to which the shaft is connected is connected to the extension portion of the second hosel portion, and the axial center line of the socket portion is perpendicular to the face surface and passes through the center of gravity of the head from the face surface to the golf ball. Since it intersects with a point spaced at the same distance as the radius, the ball is overlapped with the second hosel part, and the ball is overlapped on the extension line of the shaft. The center position can be easily adjusted. Therefore, it is possible to provide a head and a putter that can easily match the position of the center of the ball and the center of gravity of the head at the time of hitting and can accurately control the direction of rolling the ball.

  In addition, it is preferable that the center of gravity of the head is located at the same interval as the radius of the golf ball from the bottom of the head because the vertical position of the center of gravity of the head and the center of the ball is easily aligned when hit. It is.

  Further, if the socket portion is inclined with respect to the second hosel portion, the user assumes two lines having different angles: the extending direction of the second hosel portion and the extension line of the axial center of the socket portion. Therefore, the center of gravity of the head and the center of the ball can be more easily aligned.

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

The longitudinal cross-sectional view of the putter provided with the putter head of 2nd embodiment of this invention. The perspective view of the putter provided with the putter head of 3rd embodiment of this invention. The rear view of the putter provided with the putter head of the fourth embodiment of the present invention.

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

  FIG. 1 shows a putter 10 having a 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 illustration is omitted, 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 the 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. The head 12 shown in the figure is of a pin type and has weights 13 at both ends. However, 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 that connects 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. The connecting member 27 is configured. The first hosel portion 22 extends from the bottom 18 toward the top 16, and more specifically, the first hosel 22 extends in the vertical direction when the bottom 18 is grounded. Installed on the opposite side. The first hosel portion 22 is configured to pass through the center of gravity G of the head 12 as shown in FIGS. With this configuration, it is possible to prevent the face surface 14 from being inclined in the circumferential direction of the shaft 32 against the user's will when the putter 10 is shaken. The first hosel portion 22 is configured such that the center of the first hosel portion 22 is located on a vertical plane of a line Y that is perpendicular to the face surface 14 and passes through the center of gravity G of the head 12 (a plane that matches the line 2-2 in FIG. 1). Thus, the inclination of the face surface 14 with respect to the circumferential direction of the shaft 32 can be prevented.

  The second hosel portion 24 is attached to the upper end of the first hosel portion 22 and extends in the same direction as a line Y that is orthogonal to the face surface 14 and passes through the center of gravity G of the head 12 as shown in FIG. If 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. The second hosel portion 24 is on the face surface 14 side, that is, on the opposite side of the face surface 14 to the side on which the first hosel portion 22 exists, and the diameter of the golf ball B from the base 18 (golf ball standard) According to the drawing, it corresponds to 2r.) The extension portion 25 is provided at a higher position. Thus, the user of the putter 10 can overlap the second hosel part 24 with the ball B until the ball B hits the face surface 14. The direction in which the two hosel parts 24 extend can be grasped as the direction in which the ball B rolls. As shown in the figure, the first hosel portion 22 has a protruding portion 23 protruding from the upper side 16 of the head 14, and the second hosel portion 24 extends from the bottom side 18 of the protruding portion 23 to the diameter of the golf ball B. If the configuration is such that the second hosel portion 24 and the ball B are connected to each other at a higher position, the 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 part 24 can also be painted with a paint that is easily visible.

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

  As shown in the drawing, 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 18 of the head 12. According to this configuration, when the ball B is hit with the putter 10, the center of gravity G of the head 12 and the vertical position of the center of the ball B can be easily aligned, so that the force from the putter 10 can be easily transmitted to the ball B.

  As shown in FIG. 1, the socket part 26 can be configured to be inclined with respect to the second hosel part 24. With this configuration, the user can assume two lines having different angles, ie, the extending direction of the second hosel part 24 and the extension line X of the axial center of the socket part 26. Therefore, the center of gravity G of the head 12 and the ball B It is possible to make it easier to align the center position. In addition, although the inclination direction of the socket part 26 is arbitrary, as shown in the drawing, when the user inclines to the side with respect to the extending direction of the second hosel part 24, the user can see his / her own line of sight and the shaft 32 and It is easy to match the axial center of the socket part 26.

  3 and 4 show putters 10a and 10b according to 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, description of overlapping parts is omitted. In the putter 10 a shown in FIG. 3, the first hosel portion 22 is connected to the head 12 a 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. Yes. Although the detailed illustration is omitted, since the third hosel part 28 is fixed to the opposite side of the face surface 14 with a screw, the mounting angle of the third hosel part 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 10 b shown in FIG. 4, the first hosel portion 22 is rotatably fitted to the third hosel portion 28 a and tightened with a screw 29 to fix the position of the first hosel portion 22. Even in the configuration, the user can arbitrarily determine the optimum angle of the shaft 32. Moreover, the socket part 26 may be directly attached to the second hosel part 24 as shown in the drawing, or may be located at the tip of the second hosel part 24 in the extending direction.

  Further, it is also possible to adopt a configuration in which the first hosel portion 22 is inclined and attached to the head 12 as a putter 10c shown in FIG. In short, it is sufficient that the first hosel portion 22 passes through the center of gravity G of the head 12.

  As described above, according to the present invention, at the time of striking, the direction of a line that passes through the center of gravity of the head perpendicular to the face surface and the center of the ball can be easily matched, and the direction in which the ball rolls can be accurately controlled. And you can provide a putter with this.
