Problems solved by technology

Although this configuration has made it easier for a golfer to place the center of gravity of the golf club head below the center of gravity of the golf ball, it is still difficult for a golfer to achieve perfect alignment.
This results in improper alignment because the club head becomes “twisted” to an out-of-square position which results in less than the maximum amount of energy being transferred to the golf ball.

Embodiment Construction

[0017]FIG. 1 shows a golf club 10 having an iron-type golf club head 12 connected to one end of a golf club shaft 14 with a grip 16 mounted on an opposing end of golf club shaft 14. Suitable materials for golf club shaft 14 include steel and graphite. Club head 12 has a cavity back 18 in which center of gravity shifting means 20 is disposed.

[0018] Referring now to FIG. 2, an enlarged back view of iron-type golf club head 12 is illustrated. Iron-type golf club head 12 includes a body 24 and a hosel 26, which has a cylindrical bore 28 for receiving one end of golf club shaft 14. The body 24 has a heel end 30 spaced apart from a toe end 32. A sole 34 extends from a lower portion of heel end 30 to a lower portion of toe end 32, and a top rail 36 extends from an upper portion of heel end 30 to an upper portion of toe end 32. Body 24 has a front face (not shown) for impacting a golf ball that extends between heel end 30 and toe end 32 along a frontal portion of body 24. Body 24 also has ...

Abstract

A golf club head and a method for shifting the club head center of gravity. The golf club head includes a body having a front face, a back face, a heel end, a toe end, and a sole extending between lower portions of the heel and the toe ends. The golf club head also has a top rail extending between upper portions of the heel and toe ends and at least one cavity extending from the back surface into the body. Three or four weighting elements are attached to the body to shift the club head center of gravity in accordance with the desired performance of an individual golfer. The weighting elements are formed of a material which has a different density than the material forming the body.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates, in general, to golf equipment and, more particularly, to a golf club head and a method for shifting the club head center of gravity. [0002] An important factor governing the distance and accuracy of a golfer's shot is the amount of energy transferred from the golf club head to a golf ball when it impacts the golf ball. Ideally, the point of impact on the face of the golf club head is below the center of gravity of the golf club head and the point of impact on the golf ball is below the center of gravity of the golf ball. In addition, a theoretical plane containing the impact point on the golf club head, the center of gravity of the golf club head, and the center of gravity of the golf ball should be in alignment with the intended path of travel of the golf ball. When these conditions are met, the golf club head is properly aligned. [0003] To help golfers achieve proper alignment, golf club manufacturers have concentra...
