Heel and toe weighted golf club head
First Claim
1. A golf club head comprising:
- a. a main body portion of a parent material of predetermined density having shaft attachment means for the attachment of a shaft thereto;
b. said main body portion having a front striking face, a rear surface, a sole surface, a top surface and toe and heel portions;
c. said heel and toe portions defining peripheral side portions of said main body portion;
d. a plurality of weighting elements having an outer and inner surface with said outer surface located adjacent to and forming a part at least of said peripheral side portions and blended therewith, said inner surface following generally the contour of said outer surface;
e. each of said weighting elements being of a material having a density greater than said parent material;
f. each of said weighting elements having a similar predetermined shape and substantially symmetrically located about a predetermined vertical plane substantially centrally located in said main body portion which defines the intended flight line, said elements being spaced from said flight line;
g. each of said weighting elements located a predetermined distance from said sole surface and extending a predetermined distance rearwardly of said striking face;
said elements having a cross-section wherein the major dimension extends substantially parallel with said flight line andh. said weighting elements provide the club head with a center of gravity located a predetermined distance above said sole surface and a maximized area moment of inertia.

Abstract
A golf club head is formed having weighting material of a density greater than the density of the parent head material positioned at the sides of the club head to increase the inertia effect of the head. The weighting material can be arranged to increase the inertia effect of the head and at the same time shaped to locate the centre of gravity of the head in alignment with the shaft centre line. The invention also contemplates the pre-positioning of the weighting material at a specified distance from the bottom of the club head whereby the swingweight may be changed without either changing the overall weight of the club or the head and/or changing the shaft flex. The invention also provides a design of soleplate to increase the inertia effect when attached to a golf club head.
