Description

  The present invention relates to a golf putter head that is one of the components of a golf club.

  There are no putters that you must enter with a putter, and there are no putters that you never enter. However, there are good and bad putters due to individual differences. It depends on the person's physical strength, motor nerves or putting form. If the product concept of the putter matches the person, then the putter is “a good putter” for that person. The market is therefore flooded with countless types of putters. Under these circumstances, the inventors of the present invention have made it possible to select a putter grip and adjust the length in order to cover differences in height, weight, and putting style in a pendulum type putter. We have developed a putter that can adjust the weight, which incorporates the weight of the head into the design, and a putter practice machine that is suitable for use with this putter. Of these, the present invention relates to weight adjustment of a putter head.

  That is, for example, in the known putter 71 shown in FIG. 7, one relatively large weight 73 having a substantially U-shaped plane is attached to the back side of the head 72 (see Patent Document 1).

  However, in such a configuration, the user can only use a two-way selection method of whether or not the weight 73 is attached to the head 72, and thus the weight of the head 72 is finely adjusted to suit his / her preference. Since it is not possible to do so, a reversal phenomenon has occurred in which the user makes a putting form in accordance with the putter.

  In addition, it is also natural to determine your own putting form while trying out various weight heads, and it is extremely convenient if this can be done with one head or one putter.

Japanese Patent Laying-Open No. 2001-62013 (FIG. 1)

  In view of the above, an object of the present invention is to provide a putter head in which a user can adjust the weight of the head and thus can use one head as an optimum weight. In addition, an object is to provide a putter head having a function that allows a user to pick up a golf ball on the ground via the putter.

  In order to achieve the above object, a golf putter head according to a first aspect of the present invention is a head used in a golf putter, wherein a weight adjusting weight is attached to the head.
