Abstract

A putter head of a golf putter is disclosed. The putter head of the present invention is a solid monolith made of magnesium or a magnesium alloy and comprises a face including a striking surface, a back opposite the face, a neck for connecting to a shaft at a position spaced from the center of the putter head toward the heel, and two or more insertion holes formed in the back and symmetrically distributed with respect to the center of the putter head, wherein a weight is interchangeably inserted into each insertion hole, and the putter head has a weight less than or equal to half the total weight of the putter head with the weight inserted, and the angle of gravity of the putter head may have a heel hang angle due to the weight difference between the weight inserted in the insertion hole toward the heel direction and the weight inserted in the insertion hole toward the toe direction with respect to the neck. Such a putter head can provide a very flexible weight distribution design, a free angle of gravity design accordingly, and a large moment of inertia.

Description

PUTTER HEAD MADE OF MAGNESIUM ALLOY The present invention relates to a putter head made of a magnesium alloy material, and specifically, to a putter head that can provide improved putter performance by enabling a wide range of weight variation and free weight distribution design by manufacturing a lightweight putter head from a magnesium alloy material. Magnesium alloys are lightweight metals with low density among available structural materials, and are gaining attention for their excellent properties such as high specific strength, machinability, and vibration absorption. Recently, the use of these magnesium alloys is gradually increasing as they replace aluminum alloys in response to the demand for lighter transportation equipment to improve fuel efficiency. Additionally, their application is increasing in products such as mobile phones and laptops due to the demand for lightweight, compact, and excellent electromagnetic shielding properties. The putter head strikes the golf ball through the golfer's swing motion. Ideally, if the golf ball were struck precisely at the center of mass or center of gravity (COM) of the putter head, the ball would travel in a direction consistent with the putter head's direction of motion; however, since this is a human movement, this is not the case in reality. Therefore, the moment of inertia (MOI) of the putter head is important in that it reduces deviations in the ball's trajectory caused by errors in the point of impact. The greater the moment of inertia, the larger the effective striking area becomes. Various designs have been disclosed to increase the moment of inertia of putter heads. Mallet-type putter heads increase forgiveness for mishits by distributing mass through a design that extends backward. However, mallet putters have low design appeal, and the weight dragging backward makes it difficult to transfer impact power, resulting in shorter distance control. On the other hand, blade putters have the disadvantage of being difficult to control due to their narrow design. Therefore, there is a market demand for putter heads capable of providing golf putters with superior performance, such as moment of inertia.
