Abstract

Golf club heads which include an iron type golf club head body including a ball striking face, a rear surface opposite the ball striking face (e.g., including a perimeter weighting member) and an indicator which indicates the location of the center of gravity of the golf club head body. Golf clubs including these club heads and methods of making such golf club and golf club heads also are provided.

Claims (25)

1. A golf club head comprising:

an iron type golf club head body including a ball striking face and a rear surface opposite the ball striking face;

a perimeter weighting member extending rearward from the ball striking face and along at least a portion of a circumferential area of the golf club head body;

a first bridge member that extends in a first direction across a cavity in a rear portion of the golf club head body; and

a second bridge member that extends in a second direction that is different from the first direction across the cavity in the golf club head body;

wherein the first bridge member and the second bridge member cross each other; and

wherein the first bridge member and the second bridge member do not contact each other.

2. A golf club head according to claim 1 , wherein the first bridge member and the second bridge member are spaced from the rear surface opposite the ball striking face.

3. A golf club head according to claim 1 , wherein the first bridge member extends from a crown of the golf club head body to a sole of the golf club head body and the second bridge member extends generally in a heel to toe direction of the golf club head body.

4. A golf club head according to claim 1 , wherein the first bridge member is suspended from the perimeter weighting member and is positioned in the cavity off of and away from the rear surface opposite the ball striking face.

5. A golf club head according to claim 1 , wherein the first bridge member and the second bridge member both include a material that is heavier than a material of the perimeter weighting member.

6. A golf club head according to claim 1 , wherein at least one end of the first bridge member is attached to the perimeter weighting member.

7. A golf club head according to claim 6 , wherein at least one end of the second bridge member is attached to the perimeter weighting member.

8. A golf club head according to claim 1 , wherein both the first bridge member and the second bridge member have two opposed ends attached to the perimeter weighting member.

9. A golf club head comprising:

an iron type golf club head body including a ball striking face, a rear surface opposite the ball striking face, and a cavity in a rear portion of the golf club head body, such that the rear surface is located within the cavity;

a perimeter weighting member extending rearward from the ball striking face and along at least a portion of a circumferential area of the golf club head body;

a first bridge member that extends over the cavity from the perimeter weighting member; and

a second bridge member that extends over the cavity from the perimeter weighting member,

wherein the first bridge member and the second bridge member cross each other over the cavity.

10. A golf club head according to claim 9 , wherein the first bridge member extends across the cavity in a first direction, and the second bridge member extends across the cavity in a second direction different from the first direction.

11. A golf club head according to claim 9 , wherein the first bridge member and the second bridge member do not contact each other.

12. A golf club head according to claim 9 , wherein the first bridge member extends from a crown of the golf club head body to a sole of the golf club head body and the second bridge member extends generally in a heel to toe direction of the golf club head body.

13. A golf club head according to claim 9 , wherein the first bridge member and the second bridge member both include a material that is heavier than the material of the perimeter weighting member.

14. A golf club head according to claim 9 , wherein the first bridge member and the second bridge member each have two opposed ends attached to the perimeter weighting member and a center portion extending over the cavity.
