  • a shaft 110 having a circular cylinder shape is made of a material such as steel and carbon, and a certain range of the shaft 110 on an upper end functions as a grip 111 and is covered with a material which can be easily held such as rubber.
  • the head 130 having a rectangular parallelepiped-like shape is primarily made of a metal such as soft iron or alloy stainless, and a front surface of the head 130 becomes a ball-hitting surface 131 .

  • the angle can be fixed at that angle.
  • a lie angle can be adjusted by rotating the head 130 around a straight line passing through the bolt holes 113 and the bolt holes 123 which are perpendicular to the ball-hitting surface 131 and fixing the head 130 .
  • a lie angle adjusting mechanism for adjusting the lie angle is formed with the convex portion 112 , the bolt hole 113 , the bolt 121 , the concave portion 122 , and the bolt hole 123 , by rotating the head 130 around a second rotational axis which is perpendicular to the ball-hitting surface and fixing the head 130 .
  • the player can adjust the lie angle to a suitable angle corresponding to the putting style in a state where the bolt 121 is loosened and then fix the lie angle to that angle by tightening the bolt 121 .
  • a rotational shaft 124 which is parallel to the ball-hitting surface is provided in a projecting manner on a surface, of the fitting member 120 , below the concave portion 122 , and the other rotational shaft 124 is also similarly provided in a projecting manner on an opposite side on the same circumference over the main body of the fitting member.
  • These rotational shafts 124 are assembled into shaft holes 133 to be described later.
  • a hole 132 penetrating from an upper surface of the head to the bottom surface of the head is formed in the center portion of the head 130 .
  • a center of the hole 132 matches the center of the head 130 , and the length of the hole 132 in a Z axis direction (stance direction) which is horizontal and perpendicular to the X axis is slightly longer than a diameter of the fitting member 120 and a length in the X axis direction of approximately 3 ⁇ 4 of the head 130 .
  • Shaft holes 133 which are parallel to the Z axis are formed in each side wall which is parallel to the X axis forming the hole 132 , in communication with the hole 132 .
  • the shaft holes 133 are arranged in a same straight line parallel to the Z axis, and the straight line is placed to pass through the center of mass of the head 130 .
  • the shaft hole 133 has a width and a length for storing the rotational shafts 124 .
  • a guide channel for guiding the rotational shaft 124 to the shaft hole 133 is formed from the bottom surface of the head 130 to the shaft hole 133 .
  • the rotational shaft 124 is moved from the bottom surface of the head 130 along the guide channel to the shaft hole 133 .
  • the uppermost portion of the rotational shaft 124 and the uppermost portion of the shaft hole 133 contact each other, and the weight of the head 130 is supported by the uppermost portion of the rotational shaft 124 .
  • the head 130 becomes pivotable around the rotational shaft 124 which is parallel to the ball-hitting surface 131 and which passes through the center of mass of the head 130 .
  • the head 130 pivots by the weight of the head during the swing so that the angle of the ball-hitting surface with respect to the horizontal plane is maintained.
  • a rotational axis which is parallel to the ball-hitting surface 131 and which passes through the center of mass of the head 130 is formed by the straight line connecting the rotational shafts 124 .
  • a head pivoting mechanism which allows the head 130 to be pivoted by the weight of the head 130 around the rotational axis during swinging of the putter club 100 is formed by the rotational shaft 124 and the shaft hole 133 .
  • the angle of the shaft 110 with respect to the horizontal plane is inclined toward a negative side of the X-axis.
  • the head 130 is pivoted by its own weight, and the angle of the ball-hitting surface 131 with respect to the horizontal plane is maintained.
  • the head 130 is relatively pivoted with respect to the shaft 110 in a counterclockwise direction, and during the swing, the head 130 is relatively pivoted with respect to the shaft 110 in the clockwise direction, so that the angle of the ball-hitting surface with respect to the horizontal plane is maintained. In this manner, the orientation of the head 130 is maintained from the address to the completion of the swing.
  • the center of mass of the head does not exist on an extension line of the grip axis, and is shifted to the positive direction of the X-axis, that is, the swing direction.
  • the constituting elements below the rotational shaft including the head are rotationally moved relatively to the shaft toward the negative direction of the X-axis, that is, in a direction opposite to the swing, in a pendulum-like manner.
  • the center of mass of the head moves in a direction opposite to the swing, and, in the stage of the follow-through, the center of mass of the head is shifted in the negative direction of the X-axis compared to the extension line of the grip axis, that is, a direction opposite to the swing.
  • the player would feel the weight of the head in front of the grip during the back-swing, feel as if the grip overtakes the head during the swing, and feel the weight of the head behind the grip in the follow-through. In other words, the player would experience significant difficulty of hitting because of the change of the relative positional relationship between the grip and the center of mass of the head.
  • the rotational shafts 124 are aligned on one straight line which is parallel to the ball-hitting surface 131 and which is horizontal, and the straight line passes through the center of mass of the head 130 .
  • the putter club 100 is designed so that the head 130 is pivoted around the straight line as the rotational axis of the head 130 . Therefore, as shown in FIG. 3 , the relative positional relationship between the grip and the center of mass of the head does not change from the back swing through the impact to the follow-through, and it is easier to hit the ball compared to the putter club as shown in FIG. 4 .
  • the putter club 100 of the present embodiment it is possible to prevent fluctuation of the center of mass of the head 130 to the swing direction or a direction opposite to the swing direction during the swing, and to stabilize the swing.
  • the best position of the rotational shaft is at the center of mass of the head, and a putter club with the rotational shaft closer to the grip as described in Patent Literature 1 results in difficulty in hitting, and, thus, is not suited.
  • the center of mass of the head 130 is positioned on the extension line of the grip axis as shown in FIG. 3 .
  • the present invention is not limited to such a configuration, and the center of mass of the head 130 does not need to be positioned on the extension line of the grip axis, and may be slightly shifted from the extension line. In this case also, because the rotational axis of the head 130 passes through the center of mass of the head 130 , the position of the center of mass with respect to the shaft 110 is fixed.
  • the shaft 110 extends from the upper surface of the head 130 in an upward direction as shown in FIG. 1 .
  • the present invention is not limited to such a configuration, and the shaft 110 may be connected to the rotational shaft 124 passing through the center of mass of the head 130 , and is bent toward the upper direction after being extended from the side surface of the head 130 , as shown in FIG. 5 .
