Abstract

Embodiments of golf clubs head sets with varying characteristics are disclosed herein. Other examples and related methods are also generally described herein.

First claim

The invention claimed is:

1. A club head set comprising:
a first club head comprising:
a first body portion having a first toe portion, a first heel portion, a first top rail portion and a first sole portion;
a first loft angle;
a first front face;
a first backside comprising a first toe region having a first lower toe section; and
a first weight at the first lower toe section of the first toe region and comprising:
a first depth extending generally in a first backside-to-front face direction;
a first width extending generally in a first heel-to-toe direction; and
a first length extending generally in a first top rail-to-sole direction; and

a second club head comprising:
a second body portion having a second toe portion, a second heel portion, a second top rail portion and a second sole portion;
a second loft angle;
a second front face; and
a second backside comprising a second toe region having a second lower toe section; and
a second weight at the second lower toe section of the second toe region and comprising:
a second depth extending generally in a second backside-to-front face direction;
a second width extending generally in a second heel-to-toe direction; and
a second length extending generally in a second top rail-to-sole direction;

wherein:
the first loft angle is greater than the second loft angle;
the first club head comprises a short iron club head;
the second club head comprises a long iron club head; and
a dimensional relationship with respect to the first and second weights comprises:
the first depth of the first weight greater than the second depth of the second weight; and
at least one of:
the second width of the second weight greater than the first width of the first weight; or
the second length of the second weight greater than the first length of the first weight.

2. The club head set of claim 1 , wherein:
with respect to a toeside view of the first golf clubhead, the first depth is substantially orthogonal to a shaft axis of the first club head; and
with respect to a toeside view of the second golf clubhead, the second depth is substantially orthogonal to a shaft axis of the second club head.

3. The club head set of claim 2 , wherein:
the first width and the first length are substantially orthogonal to the first depth; and
the second width and the second length are substantially orthogonal to the second depth.

4. The club head set of claim 1 , wherein:
the first weight comprises a weight material;
the second weight comprises the weight material; and
a mass of the first weight and a mass of the second weight are substantially equal to each other.

5. The club head set of claim 1 , wherein:
a volume of the first weight and a volume of the second weight are substantially equal to each other.

6. The club head set of claim 1 , wherein:
a second shortest distance between the second front face and the second weight is greater than a first shortest distance between the first front face and the first weight.

7. The club head set of claim 1 , wherein:
a second shortest distance between the second front face and a center of gravity of the second weight is greater than a first shortest distance between the first front face and a center of gravity of the first weight.

8. The club head set of claim 1 , wherein:
the first club head further comprises a first hosel;
the second club head further comprises a second hosel;
a mass of the first weight counterbalances a mass of the first hosel; and
a mass of the second weight counterbalances a mass of the second hosel.

9. The club head set of claim 1 , wherein:
the first weight is visible at the first lower toe section of the first toe region; and
the second weight is visible at the second lower toe section of the second toe region.

10. The club head set of claim 1 , wherein:
the first club head further comprises a first perimeter weight at a periphery of the first backside;
the first perimeter weight comprises a first cavity at the first lower toe section of the first toe region;
the first weight is located at the first cavity;
the second club head further comprises a second perimeter weight at a periphery of the second backside;
the second perimeter weight comprises a second cavity at the second lower toe section of the second toe region; and
the second weight is located at the second cavity.

11. The club head set of claim 10 , wherein:
the first weight of the first club head is incompatible with the second cavity of the second club head; and
the second weight of the second club head is incompatible with the first cavity of the first club head.

12. The club head set of claim 1 , wherein:
a mass of the first weight and a mass of the second weight are substantially equal to each other; and
the mass of each of the first and second weights comprises approximately 5 grams to approximately 50 grams.

13. The club head set of claim 1 , wherein:
the second club head comprises one of:
a 2-iron head, a 3-iron head, a 4-iron head, or a 5-iron head;

the first club head comprises one of:
a 9-iron head, or a wedge head;

when the second club head comprises the 2-iron head, the 2-iron head comprises:
the second loft angle having a 2-iron loft angle of approximately 18 degrees to approximately 20 degrees; and
a 2-iron distance between the second front face and the second weight of approximately 1.27 mm to approximately 28.1 mm;

when the second club head comprises the 3-iron head, the 3-iron head comprises:
the second loft angle having a 3-iron loft angle of approximately 20 degrees to approximately 23 degrees; and
a 3-iron distance between the second front face and the second weight of approximately 1.22 mm to approximately 27.9 mm;

when the second club head comprises the 4-iron head, the 4-iron head comprises:
the second loft angle having a 4-iron loft angle of approximately 21 degrees to approximately 25 degrees; and
a 4-iron distance between the second front face and the second weight of approximately 1.17 mm to approximately 27.9 mm;

when the second club head comprises the 5-iron head, the 5-iron head comprises:
the second loft angle having a 5-iron loft angle of approximately 23 degrees to approximately 28 degrees; and
a 5-iron distance between the second front face and the second weight of approximately 1.12 mm to approximately 27.4 mm;

when the first club head comprises the 9-iron head, the 9-iron head comprises:
