ABSTRACT:
HEAD FOR GOLF CLUB IRONS
ABSTRACT:
ADVANCED TOP PLANE FOR STANDARD IRON

A head for a golf club iron is disclosed that provides a top planar surface for triaxial alignment of a planar striking surface substantially perpendicular to the intended path of the ball, so that the loft angle of the planar striking surface with respect tot the ball a matches a preselected loft angle, and so that the lie of the club from toe to heel is balance. The top planar surface and the planar striking surface of the club face define an angle between them equal to the preselected loft angle for the planar striking surface to define a sighting edge that is rearwardly extended from the trailing top edge of the club face for alignment of the club face perpendicular to the intended path of the ball. The top planar surface is of substantially uniform width from toe to heel and the loft and lie of the club are adjusted by holding the top planar surface horizontal.

A head for a golf club iron is disclosed that provides a top planar surface which is substantially uniform width from toe to heel and shall support an indicia perpendicular to the longitudinal axis and parallel to the intended target line of the ball. The indicia and the planar striking surface of the club face define an angle between them equal to the preselected loft angle for the planar striking surface plus 90°, and such a relationship holds true for each club of the set. When the club is in the correct address position, such a relationship shall provide the golfer with dual axial alignment to insure the planar striking surface is perpendicular to the intended target line of the ball and the loft angle of the planar striking surface, with respect to the ball, matches the preselected loft angle. The golfer will use the indicia as a sighting aid when addressing the ball, so the club head may be adjusted to ensure correct direction and loft.
