Abstract

An improved neck weighting structure for golf club heads includes a neck, a neck weighting and a weight chamber. The neck extends from a shaft mount towards the lower rim of the sole of the golf club head and straddles the lower rim of the sole to reduce the gravitational center of the club head. The neck weighting projects from the neck near the shaft mount to cause the gravitational center to deviate towards the extended line of the head. The weight chamber accommodates weights of various mass for correcting the position of the gravitational center.

Claims

1. A golf club having an improved neck weighting structure comprising a club head with a front side, a sole, a neck, a weight chamber, and a shaft mount,

said front side of said club head including a face of uniform thickness,

said shaft mount is cylindrical and adapted for receiving and positioning a shaft,

said neck of said club head extending from said shaft mount towards a lower rim of said sole of said club head and straddling said sole of said club head and adapted to lower the gravitational center of said club head,

a neck weighting projecting from said neck near said shaft mount, said neck weighting for moving the gravitational center to an extended line of the golf club, and

said weight chamber is disposed at a central position of said neck for accommodating weights of different mass for correcting the gravitational center of said club head when the gravitational center deviates from a predetermined area.

2. An improved neck weighting structure as claimed in claim 1, wherein a joint between said neck and said shaft mount is configured to have a substantially S-shape for holding said neck and said shaft mount at different elevations.
