Adjustable balance weighting system for golf clubs
First Claim
1. In a golf club adapted to be utilized with a full swing, an iron or wood type golf club head having a front striking surface, a top surface and a rear surface, comprising:
- eccentric weighting means for adjusting the balance and weight of the golf club, said eccentric weighting means including at least one eccentric weight, the at least one eccentric weight being of a non-dynamic character so as not to impart additional force to a golf ball when struck by said club head; and
mounting means for rotatably mounting said eccentric weighting means upon at least one of said top and rear surfaces.

Abstract
An adjustable balance weighting system (10) is provided for adjusting the weighting and balance of a golf club of either the "iron" or the "wood" type in order to encourage the golf club to be in tune with the golfer'"'"'s swing and/or to correct any deficiencies that may exist therein. An eccentrically weighted balancing disk (32 or 82) is mounted on or in the club head (14 or 74) so as to be rotatable about a first Allen screw (60 or 84) and provides a mechanism by which the center of mass, and therefore the sweet spot, of the club head (14 or 74) may be varied. In the case of an iron-type club head (14), the balancing disk (32) is mounted in a substantially vertical orientation in a cavity (30) on a cavity back wall surface (40) at the rear face (24) of the club head (14). In the case of a wood-type club head (74), the balancing disk (82) is mounted in a horizontal orientation in a recess (80) in the top surface (78) of the club head (74). When adjustment is needed, a second Allen screw (68 or 86) is conveniently loosened so that the balancing disk (32 or 82) may pivot and be turned to a desired orientation, thereby causing more weight to be transferred to either the toe or heel of the club head (14 or 74), as necessary, to correct a "slice" or a "hook," respectively. Provision is also made for the use of the adjustable balance weighting system (10) in the context of the "fitting" of golf clubs so that a permanent adjustment is made.

10. In a golf club adapted to be utilized with a full swing, a method of adjusting the weight and balance of the associated club head, the club head being of iron or wood type having a front striking surface, a top surface, a rear surface, a toe and a heel, comprising the steps of:
-
providing at least one eccentrically balanced weight having a heavier portion and a lighter portion, said eccentrically balanced weight being of a non-dynamic character so as not to impart additional force to a golf ball when struck by said club head; adjustably mounting said eccentrically balanced weight in rotatable fashion upon at least one of said top and rear surfaces; and rotatably orientating said eccentrically balanced weight such that the heavier portion is moved closer to said toe to correct a golfer'"'"'s slice, and rotatably orientating said eccentrically balanced weight such that the heavier portion is moved closer to said heel to correct a golfer'"'"'s hook. - View Dependent Claims (11, 12, 13)
