Golf club head with improved weight distributions
First Claim
1. A metal golf club head having a toe, a heel, a body extending between said toe and said heel, said body having a front striking face and a rear, a cavity-back in the rear of the body surrounded by a top rim, a bottom rim, a heel rim, and a toe rim, a hosel extending upwardly from said heel for receiving a golf club shaft, and a hollow toe rim cavity in the toe rim, said toe rim cavity positioned above the bottom rim and containing an insert of material which has a lower density than the metal.

Abstract
A golf club head having improved weight distributions to enhance important moments of inertia of the club head. A hollowed out toe rim cavity is provided in the toe portion of the periphery of the club head which is filled with a lightweight compressible material. The toe rim cavity and insert combination relocates the center of gravity of the club toward the heel, making the club easier to close at impact. The toe rim cavity and insert also redistribute mass on the toe portion of the club, increasing the moment of inertia about the horizontal axis of the club head. The insert also attenuates the vibrations generated at impact between the club head and a golf ball.

18. A metal golf club head having
a toe, a heel, a body extending between said toe and said heel, said body having a front striking face, a lower leading edge, and a rear, and including a center of gravity, a cavity-back in the rear of the body surrounded by a top rim, a bottom rim, a heel rim, and a toe rim, a hosel extending upwardly from said heel for receiving a golf club shaft, a weight member projecting outwardly from an angular segment of the periphery of said hosel, wherein said angular segment is less than 360° - ,
a hollow toe rim cavity in the toe rim, said toe rim cavity positioned above the bottom rim and further positioned such that a horizontal line containing the center of gravity and generally parallel to the lower leading edge passes through said cavity, said toe rim cavity tapering in thickness such that its thickness in a plane generally parallel to the striking face of the club decreases upwardly along the toe rim, said toe rim cavity further tapering in thickness such that its thickness in a plane generally perpendicular to the striking face of the club decreases upwardly along the toe rim, and an insert of material which has a lower density than the metal contained within said cavity. - View Dependent Claims (19, 20, 21, 22)
