Correlated set of golf club heads
View Patent ↗A correlated set of golf club heads is provided. The set of golf clubs has a first club head that, when oriented in a reference position, includes: a first loft angle, a first heel portion, a first toe portion opposite the first heel portion, a first top portion, and a first sole portion that comprises a first sole rail having a first setback length. The set of golf clubs also has a second club head that, when oriented in the reference position, includes: a second loft angle greater than the first loft angle, a second heel portion, a second toe portion opposite the second heel portion, a second top portion, and a second sole portion that comprises a second sole rail having a second setback length that is different from the first setback length.
1. A correlated set of golf club heads comprising:
a first non-wedge, iron-type club head that, when oriented in a reference position, includes:
a first loft angle;
a first heel portion;
a first toe portion opposite the first heel portion;
a first top portion; and
a first sole portion comprising a first bottom surface, a first rearward surface, and a first sole rail having a first maximum thickness proximate the first bottom surface; and
a second non-wedge, iron-type club head that, when oriented in the reference position, includes:
a second loft angle greater than the first loft angle;
a second heel portion;
a second toe portion opposite the second heel portion;
a second top portion; and
a second sole portion comprising a second bottom surface, a second rearward surface, and a second sole rail having a second maximum thickness proximate the second bottom surface such that:
the second maximum thickness is less than the first maximum thickness;
a first absolute difference between the first maximum thickness and the second maximum thickness is no less than about 0.5 mm; and
a second absolute difference between the first loft and the second loft is no greater than 12 degrees.
2. The correlated set of claim 1 , wherein at least one of: (a) the first maximum thickness is no less than about 0.50 mm; and (b) the second maximum thickness is no less than about 0.50 mm.
3. The correlated set of claim 1 , wherein at least one of: (a) the first sole rail is associated with the first bottom surface and the first rearward surface of the first sole portion; and (b) the second sole rail is associated with the second bottom surface and the second rearward surface of the second sole portion.
4. The correlated set of claim 1 , wherein at least one of: (a) a first thickness of the first sole rail forwardly tapers; and (b) a second thickness of the second sole rail forwardly tapers.
5. The correlated set of claim 1 , wherein at least one of the first club head and the second club head comprise at least two discrete sole rails.
6. The correlated set of claim 1 , wherein at least one of the first sole rail and the second sole rail further comprise a central groove generally extending in the forward to rearward direction.
7. The correlated set of claim 1 , wherein each of the first club head and the second club head comprise an iron-type club head.
8. The correlated set of claim 1 , wherein the first club head further comprises a first setback length and the second club head further comprises a second setback length such that at least one of the first setback length and the second setback length is no less than about 5 mm.
9. The correlated set of claim 8 , wherein at least one of the first setback length and the second setback length is no less than about 8 mm.
