Description

  The present invention relates to a golf putter head capable of changing the shape of the putter head, and more particularly to a golf putter head capable of changing the function of the putter head in accordance with the shape of the putter head.

  The head of the golf club is designed so that force can be more reliably transmitted to the golf ball when the golf ball is hit with the hitting surface. For example, in the putter used on the green, the golf ball rolling distance is determined by adjusting the delicate force of the player, and the golf ball rolling direction is determined by the angle of the hitting surface at the time of collision. In order to ensure transmission, physical characteristics such as the weight of the head, the position of the center of gravity, the rigidity of the hitting surface, and the hardness are important factors.

  By the way, the player sets the shape of the grip and the length of the shaft in accordance with his / her body shape and play style, and then selects the optimum one from various heads to create the optimum golf club. . In addition, golf clubs of various shapes have been proposed according to the trend, for example, there are putters with various designs and putter heads having a center of gravity position according to the design. It can be selected according to.

  On the other hand, golf is a sport with a great psychological influence, and it is difficult to give the same score with the same putter depending on the condition of the day of play. Therefore, the player usually has a plurality of golf clubs having different positions of the center of gravity, and selects the optimum putter according to the condition of the day of play and the green situation, and wants to play.

  However, since the putter itself is very expensive, it is economically difficult to have a plurality of putters and there is a problem that a storage space is required. Also, in a store that sells golf clubs, in order to meet the demands of various players, many types of golf clubs must be kept in stock at the store. For this reason, there is a problem that enormous costs are required for inventory management.

From such a problem, there is a putter that allows a player to easily select an optimal center of gravity position with one golf putter (Patent Document 1).
The golf putter described in Patent Document 1 includes a club head including a club face portion and a head body extending rearward from the center of the rear surface of the club face portion. A sliding groove extending in the front-rear direction is formed on the upper surface of the head body, and a sliding body having a neck body is slidably supported in the sliding groove, and the sliding body is supported by the head body and the sliding body. Fixing means for changing the position of the center of gravity of the club head back and forth by fixing at an arbitrary sliding position of the main body is provided.
With such a configuration, the player himself / herself can selectively move the center of gravity of the club head back and forth in accordance with the condition of the green grass on the golf course.

JP 2006-198385 A

  However, the above putter has the advantage that the center of gravity of the club head can be selectively moved back and forth with a single putter, but the shape of the putter head itself cannot be changed. Since the player places importance on the shape of the putter head in addition to the center of gravity of the putter head when selecting the putter, the player tends to have a plurality of putters or frequently replace them with various shapes. For these reasons, even a putter that can selectively move the center of gravity position back and forth cannot change the shape, and eventually becomes a target to be replaced.

  However, as described above, a golf club is expensive, and it is difficult to easily have a plurality of golf clubs. Further, even if the golf club can be replaced, there is a problem that it takes time and effort because it is necessary to set the shape of the grip and the length of the shaft every time the golf club is replaced.

  The present invention has been made in view of such problems, and an object thereof is to provide a golf putter in which the shape of the putter head can be easily changed and the function of the putter can be changed.

  In order to achieve the above object, a golf putter head according to the present invention includes a striking face portion that forms a striking surface, a back portion having a plurality of shapes or depths of gravity provided on the back surface of the striking surface of the striking face portion, The back portion is configured to be replaceable and fixable with respect to the hitting face portion.

  The golf putter head according to the present invention is characterized in that the back portion is formed with weight members at the rear at both end portions.

  Furthermore, the golf putter head according to the present invention is characterized in that a weight member is formed from the center to the back of the back portion.

  According to the present invention, since the player can easily attach weight members having various positions of the center of gravity, the weight member can be changed to a weight member having a position of the center of gravity that matches the player's preference and the condition of the day of play.
