Abstract

The present invention is direct to a set of golf clubs comprising long irons, mid-irons and short irons. The invention contemplates the use of titanium or steel for the main body portion and significant tungsten weight members coupled to at least the toe via a mechanical fastener.

Claims

1. A set of golf clubs comprising at least a first club head having a loft between about 15 and 25 degrees, a second club head having a loft of between about 26 and 35 degrees, and a third club head having a loft of about 36 degrees or greater, wherein:

the first, second and third club heads each comprise a heel, a toe, a topline, a sole, a hosel and a front face having a face center, each club head having a club head mass that is different than the previous club head by at least 5 grams, and wherein at least one of the club heads includes a weight member formed of tungsten and coupled to the toe that comprises 15%-25% of the club head mass.

2. The set of golf clubs of claim 1, wherein the weight member is coupled to the golf club to form a portion of the back surface, the toe surface and the sole surface.

3. The set of golf clubs of claim 2, wherein the weight member is coupled to the club head via a mechanical fastener.

4. The set of golf clubs of claim 3, wherein the club includes an indentation that forms a wall surrounding a portion of the weight member.

5. The set of golf clubs of claim 4, wherein the wall forms an angle between about 10 degrees and 60 degrees such that the weight member is press fit against the wall when the mechanical fastener is tightened.

6. The set of golf clubs of claim 5, wherein the club includes a bottom surface and an adhesive tape is juxtaposed the bottom surface and the weight member.

7. The set of golf clubs of claim 2, wherein the mechanical fastener is inserted through a face side of the club and extends through an aperture in the club.

8. The set of golf clubs of claim 2, wherein the club and the weight member form a paint fill edge that surrounds the weight member perimeter.

9. A set of golf clubs comprising at least a first club head having a loft between about 15 and 25 degrees, a second club head having a loft of between about 26 and 35 degrees, and a third club head having a loft of about 36 degrees or greater, wherein:

the first, second and third club heads each comprise a solid volume, a heel, a toe, a topline, a sole, a hosel and a front face having a face center, wherein at least one of the club heads has an overall club head mass and is comprised of a steel body member and a steel face insert that together comprise less than 75 percent of the overall club head mass and is further comprised of at least a toe weight member formed of tungsten, wherein the weight member comprises between 15% and 25% of the club head mass and is coupled to the body member by a mechanical fastener such that weight member forms a portion of a sole surface, a toe surface and a back surface.

10. The set of golf clubs of claim 9, wherein the first and second club heads each comprise a steel body member and a steel face insert and toe weight member is coupled to the body member by the mechanical fastener which is inserted through a face side of the body and extends through an aperture in the body to couple with the weight member.

11. A set of golf clubs comprising at least a first golf club, a second golf club, and a third golf club, wherein:

the first, second and third golf clubs are each comprising a heel, a toe, an upper surface, a lower surface, a hosel and a front face having a face center, and

the first golf club further comprising a first loft angle (LA₁) of between 15 and 25 degrees and a first blade length, a first hosel length and a first scoreline width,

the second golf club comprising a second loft angle (LA₂) of between 26 and 35 degrees and a second blade length, a second hosel length and a second scoreline width, and

the third golf club comprising a third loft angle (LA₃) of 36 degrees or greater and a third blade length, a third hosel length and a third scoreline width, wherein the first golf club has a first tungsten toe member, the second golf club has a second tungsten toe member with greater mass than the first tungsten toe member and the third golf club has a third tungsten toe member with greater mass than the second tungsten toe member.

12. The set of golf clubs of claim 11, wherein the each of the tungsten toe members are coupled to the clubs via a mechanical fastener such that the weight member forms a portion of a sole surface, a toe surface and a back surface.
