ABSTRACT:
Adjustable balance weighting systems (10 and 110) are provided for adjusting the weighting and balance of golf clubs of either the "iron" or the "wood" types. An eccentric weighting means is mounted on or in the club head (14 or 74) so as to be rotatable and provide 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), an eccentrically weighted disk (32) is mounted in a substantially vertical orientation on the rear face (24) of the club head (14). In the case of a wood-type club head (74), a similar disk (82) is mounted in a horizontal orientation in a recess (80 or 89) in a top or bottom surface (78 or 87) of the club head (74). When adjustment is needed, a screw (68 or 86) is conveniently loosened so that the 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. In an alternative embodiment for wood club heads (112), eccentric weighting is provided by a rotatable sole plate (130) with an attached weight (156) eccentrically located thereon. In a further enhancement to the adjustable balance weighting system, there is also provided, in the case of wood clubs, an oversized club head (112) of a substantially ellipsoidal shape. The redistribution of weight afforded gives greater controllability and allows a more effective use of the already increased sweetspot provided by an oversized club head.
