Set of golf clubs
View Patent ↗At least three clubs of a set of golf clubs may have an average volume between about 75 cm 3 and about 90 cm 3 . The transverse dimensions of the at least three clubs may progressively decrease from a highest volume club to a lowest volume club. At least one club of a set may include a constraining member in a cavity. A linear distance between a sweet spot and a center of gravity may progressively decrease from a lower lofted club to a higher lofted club within a set. At least one golf club of a set may include a face plate portion, and at least two golf clubs of the set may include a cup face portion. At least two clubs of a set may include a progressively increasing hosel length from a lowest lofted club to a highest lofted club. The strike face of at least one club of a set may include a bulge and a roll. A first club of a set may have a face thickness that is less than a face thickness of a second club of the set.

each club of the set including a club head comprising:
a shell;
a face member comprising a striking surface;
a loft of at least 20°; and
a transverse dimension at a vertical height between about 2 mm and about 10 mm above the ground plane;
at least three club heads of the set having different volumes, the at least three club heads having an average volume between about 75 cm 3 and about 90 cm 3 , the transverse dimensions of the at least three club heads progressively decreasing from the highest-volume club heads to the lowest-volume club head.
2. The set of claim 1 , wherein at least one club head comprises at least two articulation points.
3. The set of claim 1 , wherein the shell of each of at least three club heads comprises a concavity, and the striking surface of each of at least two club heads comprises a bulge and a roll.
4. The set of claim 1 , wherein:
each of at least two club heads comprises a cavity at least in part bounded by the shell and the face member;
the shell of each of the at least two club head comprises a cup face coupled to the shell at a second peripheral edge, and
at least one club head comprises a constraining member in the cavity.
5. The set of claim 1 , wherein:
the face member of at least one club head comprises a strike plate coupled to the shell at a first peripheral edge, and
the face member of each of at least two club heads comprises a cup face coupled to the shell at a second peripheral edge.
6. The set of claim 1 , wherein:
the face member of at least one first club head has a loft between 20° and 47° and comprises a first face thickness, and
the face member of at least one second club head has a loft between 20° and 47° and comprises a second face thickness, the second face thickness being greater than the first face thickness.
7. The set of claim 1 , wherein:
at least three club heads of the set have different lofts, each of the at least three club heads further comprising a hosel having a hosel length, the hosel lengths of the at least three club heads progressively increasing from the lowest-lofted club head to the highest lofted club head.
8. The set of claim 1 , wherein at least one club head comprises a first resonant frequency of vibration between about 3000 Hz and about 7000 Hz.
9. The set of claim 1 , wherein the at least one club head comprises a loft that is greater than 30°.
10. The set of claim 1 , wherein:
at least three club heads of the set have different lofts, each of the at least three club heads further comprising a hosel having a hosel length, the hosel lengths of the at least three club heads progressively increasing from the lowest-lofted club head to the highest-lofted club head, and
the striking surface of at least one club head comprises a bulge and a roll.
