Abstract

A set of ball striking devices, such as a set golf clubs, having distinct groupings of characteristics between clubs within the set of clubs such as club length, club head weight, club head lie angle, and club head offset. The set of golf clubs can include iron-type clubs, hybrid-type clubs, and wood-type clubs.

First claim

1 . A set of golf clubs comprising:
a plurality of iron-type golf clubs, each iron-type golf club comprising: an iron-type golf club head having a striking face configured for striking a ball and a body extending rearwardly from the striking face, the body having a top surface, a sole, a heel, and a toe, and a hosel including a hosel axis, wherein each of the iron-type golf club heads is a cavity back club head; and a shaft configured to engage with the iron-type golf club head, wherein each iron-type golf club head has a lie angle, a loft angle, an offset and a club head weight, wherein each iron-type golf club has a club length, wherein the plurality of iron-type golf clubs comprises at least five iron-type golf clubs; wherein the club length of each iron-type golf club is one of a first club length, a second club length, or a third club length; wherein the first club length is greater than the second club length, wherein the second club length is greater than the third club length, and further wherein at least two iron-type golf clubs have the same club length as the first club length and at least two iron-type golf clubs have the same club length as the second club length; and wherein a difference between the second club length and the third club length is two inches.

2 . A set of golf clubs of claim 1 , wherein the lie angle of each iron-type golf club head is one of a first lie angle, a second lie angle, a third lie angle, or a fourth lie angle;
wherein the first lie angle is lower than the second lie angle, the second lie angle is lower than the third lie angle, and the third lie angle is lower than the fourth lie angle.

3 . A set of golf clubs of claim 1 , wherein the club head weight of each of the iron-type golf club heads is one of a first club head weight, a second club head weight, or a third club head weight, and further wherein the first club head weight is lower than the second club head weight, and wherein the second club head weight is lower than the third club head weight.

4 . A set of golf clubs of claim 1 , wherein the loft angle of each iron-type golf club head is in a range between 24 degrees and 60 degrees.

5 . A set of golf clubs of claim 4 , wherein the plurality of iron-type clubs comprises;
a first iron-type club having a loft angle in a range of 30 degrees to 34 degrees; a second iron-type club having a loft angle in a range of 38 degrees to 42 degrees; a third iron-type club having a loft angle in a range of 43 degrees to 47 degrees; a fourth iron-type club having a loft angle in a range of 48 degrees to 52 degrees; a fifth iron-type club having a loft angle in a range of 44 degrees to 48 degrees; and a sixth iron-type club having a loft angle in a range of 54 degrees to 58 degrees.

6 . A set of golf clubs of claim 5 , wherein the club length of at least two iron-type golf clubs is the third club length.

7 . A set of golf clubs of claim 1 , wherein the plurality of iron-type golf clubs comprises at least 7 iron-type golf clubs.

8 . A set of golf clubs of claim 1 , wherein the plurality of iron-type golf clubs comprises at least 8 iron-type golf clubs.

9 . A set of golf clubs of claim 1 , wherein the first club length is in a range between 36.5 inches and 37.5 inches.

10 . A set of golf clubs of claim 1 , wherein the second club length is in a range between 34.5 inches and 35.5 inches and the third club length is in a range between 32.5 inches and 33.5 inches.

11 . A set of golf clubs of claim 1 , wherein the offset of the iron-type club heads with the lowest loft angle is less than the offset of the iron-type club head with the highest loft angle.

12 . A set of golf clubs of claim 1 , wherein each iron-type golf club head has a center of gravity that has a substantially similar height when measured in a direction perpendicular to the ground plane, when the club head is oriented in its reference position.

13 . A set of golf clubs comprising:
at least one hybrid-type golf club comprising: a hybrid-type golf club head having a striking face configured for striking a ball and a body extending rearwardly from the striking face enclosing a hollow portion, the body having a crown, a sole, a heel, and a toe, and a hosel including a hosel axis, wherein the hybrid-type golf club head has a first head breadth dimension defined from a forwardmost edge to a rearmost edge within a range of 51 mm to 73 mm and a CFY dimension between 6 mm and 15 mm defined as a distance in a front-to-back direction from a center of the hosel to a center of the striking face; a shaft configured to engage with the hybrid-type golf club head; wherein the at least one hybrid-type club has a first club length; wherein the at least one hybrid-type golf club head has a first lie angle, and a first club head weight; and a plurality of iron-type golf clubs, each iron-type golf club comprising:
an iron-type golf club head having a striking face configured for striking a ball and a body extending rearwardly from the striking face, the body having a top surface, a sole, a heel, and a toe, and a hosel including a hosel axis;
wherein the plurality of iron-type golf clubs comprises at least five iron-type golf clubs, wherein the iron-type golf club heads is a cavity back club head;
a shaft configured to engage with the iron-type golf club head; wherein each golf club head has a lie angle, a loft angle and a club head weight;
wherein each of the iron-type golf clubs has a club length;
wherein the club length of each of the iron-type golf club is one of a second club length, a third club length, or a fourth club length; wherein the first club length is greater than the second club length, and wherein the second club length is greater than the third club length; and the third club length is greater than the fourth club length; and
wherein the club length of at least two iron-type golf clubs are the second club length and the club length of at least two iron-type golf clubs are the third club length.

14 . A set of golf clubs of claim 13 , wherein the lie angle of each iron-type golf club head is one of a second lie angle, a third lie angle, a fourth lie angle, or a fifth lie angle.

15 . A set of golf clubs of claim 13 , wherein the club head weight of each of the iron-type golf club heads is one of a second club head weight, a third club head weight, or a fourth club head weight.

16 . A set of golf clubs of claim 13 , wherein the loft angle of each iron-type golf club head is in a range between 24 degrees and 60 degrees.

17 . The set of claim 13 , wherein the plurality of iron-type clubs comprises;
a first iron-type club having a loft angle in a range of 30 degrees to 34 degrees; a second iron-type club having a loft angle in a range of 38 degrees to 42 degrees; a third iron-type club having a loft angle in a range of 43 degrees to 47 degrees; a fourth iron-type club having a loft angle in a range of 48 degrees to 52 degrees; a fifth iron-type club having a loft angle in a range of 44 degrees to 48 degrees; and a sixth iron-type club having a loft angle in a range of 54 degrees to 58 degrees.

18 . (canceled)
