US 2003/0195056 A1 · Correlated set of golf club irons

Abstract

In one aspect, a correlated set of individually numbered golf club iron heads progresses from a high numbered head to a low numbered head. Individual heads have a front striking face, a rear face, a sole, a toe, a heel and a hosel. The front striking faces of heads within the set individually have a total planar area defining a progressively decreasing loft angle in going from the high numbered head to the low numbered head. For at least two chosen pairs of heads within the set, the striking face total planar area of individual heads within each chosen pair increases in size in going from the higher numbered head to the lower numbered head in the pair. In another aspect, a correlated set of individually numbered golf club iron heads comprises at least a 3-iron head, a 4-iron head and a 5-iron head. The hosel is provided relative to the sole to provide a different and increasing lie angle in sequentially progressing from the 3-iron head to the 5-iron head. The heads within the set define a 3-iron and 4-iron pair of heads and a 4-iron and 5-iron pair of heads. The sum of the differences between the lie angles in the 3-iron/4-iron pair and between the lie angles in the 4-iron/5-iron pair are less than or equal to about 1.0°.

the front striking faces of clubs within the set individually having a total planar area defining a progressively decreasing loft angle in going from the high numbered club to the low numbered club;
for at least two chosen pairs of clubs within the set, the striking face total planar area of individual clubs within each chosen pair increasing in size in going from the higher numbered club to the lower numbered club in the pair.

A correlated set of individually numbered golf clubs comprising at least a 3-iron club, a 4-iron club and a 5-iron club, individual clubs having a front striking face, a rear face, a sole, a toe, a heel and a hosel;

the hosel being provided relative to the sole to provide a different and increasing lie angle in sequentially progressing from the 3-iron club to the 5-iron club, the clubs within the set defining a 3-iron and 4-iron pair of clubs and a 4-iron and 5-iron pair of clubs;
and
the sum of the differences between the lie angles in the 3-iron/4-iron pair and between the lie angles in the 4-iron/5-iron pair being less than or equal to about 1.0°.
