Description

Putter with loft angle adjustment function

The present invention relates to a putter capable of adjusting a loft angle, and in particular, is constituted by a simple structure, and a head loft angle of a putter can be adjusted to an angle desired by a user, and a function of sand wedge, pitching wedge, The present invention relates to a putter capable of reducing the number of golf clubs to be brought to the golf course while reducing the economic cost,

Generally, a golf club is basically a full set of 14 clubs including woods 1, 3, 4, 5, irons 3, 4, 5, 6, 7, 8, 9, pitching wedges, sand wedges, . Half sets of clubs are mainly wood 1, 3, irons 3, 5, 7, 9, sand wedges, and putters.

When playing golf, the distance varies depending on the distance and condition of the hole, but tee shot and putting should be done basically.

Tee shot is important, but putting is the most important thing in ranking.

In order to perform the putting, the golfer grasps the state of the green and matches the hole with the golf ball and the putter.

During the putting, the putter is putted by varying the angle between the putter and the ground according to the state of the green, that is, the season and humidity, the weather, the grass condition, and the golfer adjusts the angle of the putter by adjusting the putting posture.

However, as described above, there is a problem that the golfer is unable to put in the correct posture by arbitrarily adjusting the angle, that is, by bending one leg or bowing the upper body.

Also, there are golfers who use a lot of putters having different angles without adjusting the posture as described above. In this case, there is a problem that purchase cost is increased by purchasing each equipment according to the state of green, and the state of green changes from time to time It is very difficult to purchase a putter according to the state of the above green

On the other hand, there is also a loft angle at the face of the putter. If there is no loft at all, when the impact is applied, the ball rubs against the painted surface and the speed drops and the ball flares. On the other hand, if it is too much, the ball will float away and become bound and the directionality will deteriorate.

Thus, it is desirable to maintain an appropriate loft for the ball to roll smoothly.

The lie angle of the putter is adjusted according to the change of the swing weight of the putter. The lie angle of the putter is changed according to the shaft length of the putter, the grip position, the swing mode, etc., The front or rear of the putter should be adjusted so that it falls equally on the ground or touches the ground.

As a prior art for adjusting the loft angle of a putter, as disclosed in Korean Patent Laid-Open Publication No. 10-2010-0000355 entitled " Putter having an angle adjusting function of a head "(published on Jan. 1, 2010) A front and rear angle adjuster for adjusting the angle of the putter and a left and right angle adjuster for adjusting the angle of the head left and right so as to adjust the head angle of the putter according to the state of the green when putting Thereby enabling stable putting.

In this case, there is a function that an angle adjusting bolt which is fastened to the angle adjusting bolt fastening hole is fastened to the angle adjusting rod so that the loft angle of the head is adjusted according to the rotation of the angle adjusting bolt. It is complicated and there is a possibility that the threaded portion is easily broken by the hitting force hitting the golf ball.

As another prior art related to putter, there has been proposed a method of putting an arm on a putter as described in Korean Utility Model Registration No. 20-0319966, "Loft and Lie Angle Adjustment Device for Golf Putter" (registered on July 23, 2003) And an upper joint capable of adjusting a lie angle of an adjusting screw is formed by inserting a support shaft of a grip member formed with teeth into a shaft hole formed in an upper end of the arm, and a support shaft having teeth at a lower end of the arm is formed, A shaft is attached to a putter through an arm formed with an upper joint and a lower joint, a lie angle of a shaft is adjusted by an upper joint, and a loft of a putter is adjusted by a lower joint .

However, the existing putter has merely a function of adjusting the angle of the head, and the means for realizing it is complicated, and it is also difficult to precisely adjust the angle.

Korean Patent Laid-Open Publication No. 10-2010-0000355 "Putter having an angle adjusting function of head" (Published date: 2010.01.06) Korean Registered Utility Model Registration No. 20-0319966 "Loft and Lie Angle Adjustment Device for Golf Putter" (Registered on July 2, 2003)
