Description

  The present invention relates to a golf club head capable of adjusting the position of a center of gravity according to a user's heel by changing a fixed position of a weight.

  Conventionally, if a golf club head having a relatively high center of gravity is used, the launch angle and the flight trajectory of the hit golf ball are adversely affected. Thus, many club heads have an integral weight that is cast into the head in place to lower the center of gravity of the club head.

  However, a person who plays golf often has a certain kind of heel on a swing, and a certain person has a feature that the ball is sliced or a certain person hooks the ball. Although such a hitting ball can be used to a golf club suitable for the person at all times, it is difficult to find the tool that suits him from the standard products, and a new If you buy a golf club, you must get used to it again. In this way, it is necessary to be able to adjust the position of the center of gravity in addition to lowering the center of gravity of the club head.

  By the way, some conventional golf club heads have a lowered center of gravity, but such ones have a fixed weight with a weight inside the golf club head body, so that the center of gravity is further increased. Adjustment is not possible, manufacturing is difficult, and the center of gravity can be lowered.

  Therefore, in view of such a situation, the present invention can adjust the position of the center of gravity of the golf club head by taking a weight balance according to the user's technique, physical strength, swinging habit, etc. The primary object is to provide a golf club head.

  A second object of the present invention is to provide a golf club head that further lowers the center of gravity.

  In order to achieve the above object, the present invention is designed so that the striking surface for striking the ball and the striking surface from the left and right sides of the striking surface are connected to each other on the basis of the posture immediately before the moment of hitting the ball. A golf club head having a rear side surface extending to the rear side surface, wherein the weight is adjustable on the rear side surface so that weights are movably attached to the left and right sides of the striking surface. Provide the head.

  Note that an arc-shaped guide load is formed on the rear side surface from the two locations, both ends of which are close to the left and right sides of the striking surface, leaving a gap between the rear side surface and extending between the two locations. The weight provides a golf club head with an adjustable center of gravity that is movably and lockably attached to the guide load.

  Since the weight of the golf club head having the above-described structure is attached so that the weight is movable along the rear side toward the left and right sides of the striking surface, the center of gravity can be easily adjusted from the outside by the movement of the weight. Even simple.

  In addition, the arc-shaped guide load holding the weight protrudes backward from the rear side surface of the golf club head, so that the position of the weight can be moved slightly rearward to further lower the center of gravity. it can.
