Description

Shaft angle adjuster of golf putter

The present invention is a technique for adjusting the shaft angle of the golf putter and maintain the current state even when the adjusted angle is impacted by the putting.

In particular, the present invention relates to a technology that enables precise adjustment of the angle at the time of adjusting the angle of the shaft, as well as preventing the sliding phenomenon from the impact of the putting at the adjusted angle.

The golf putter is composed of a putter head that strikes the golf ball directly when putting and a handle rod extending upward from the putter head to grip the user.

Here, since the angle between the putter head and the handle rod is different depending on the user's hitting habits and physical conditions, adjusting the angle between the putter head and the handle rod to the user is common in golf putters.

Meanwhile, the angle at which the handle rod is inclined between the front of the user and the rear of the user with respect to the putter head while the user grips the handle rod is called a 'lie angle'.

In addition, the angle of the inclination of the handle rod between the left and the right of the putter head while the user of the right hand grips the handle rod is called a 'loft angle'.

Therefore, adjusting the angle of the handle rod with respect to the putter head depends on how much the lie angle and the loft angle of the handle rod are ultimately determined.

Conventionally, at least one connection member is provided at a portion connecting the putter head and the handle rod, and the coupling member is coupled between the head and the head portion or between the connection members in a threaded manner. That is, the 'lie angle' or 'loft angle' is adjusted according to the engagement position of the threads.

Here, since the angle (approximately 2 degrees) of the handle rod according to a pitch movement of the thread is specified, in order to precisely adjust the angle of the handle rod, the thread must be made small and tight.
