Abstract

A golf club head is disclosed that includes a weight integral to a bridge member extending across a cavity back golf club head. The weight modifies a position of a center of gravity of the golf club head. The weight is independently movable in multiple directions to further vary the center of gravity of a golf club head.

Claims (35)

1. A set of iron golf clubs, the set of iron golf clubs comprising:

a plurality of increasing numbered iron golf clubs, the plurality of increasing numbered iron clubs each having a shaft and a golf club head, the golf club head positioned on an end of the shaft, the golf club head of each iron golf club comprising:

a striking face that provides a contact area for engaging a golf ball;

a rear cavity opposite the striking face;

a bridge member extending across the rear cavity;

a rail extending through a front surface and a back surface of the bridge member; and

a weight movably attached to the rail, the weight attached to the bridge member to vary a position of a center of gravity of the golf club head with respect to the striking face.

2. The set of iron golf clubs of claim 1 , wherein the weight comprises a weight chip.

3. The set of iron golf clubs of claim 1 , wherein is movable in three dimensions with respect to the striking face to vary a position of a center of gravity of the golf club head with respect to the striking face.

4. The set of iron golf clubs of claim 1 , wherein the weight is rotated and fixed in different positions to further vary the position of a center of gravity of the golf club head with respect to the face.

5. The golf club head of claim 1 , wherein the weight is interchangeable with one of a plurality of alternate weights.

6. The golf club head of claim 5 , wherein at least one of the alternate weights has a different mass than the weight.

7. The set of iron golf clubs of claim 1 , wherein the set of iron golf clubs is selected from the group consisting of a two iron, a three iron, a four iron, a five iron, a six iron, a seven iron, an eight iron, a nine iron, and a pitching wedge.

8. A set of iron golf clubs, the set of iron golf clubs comprising:

a plurality of increasing numbered iron golf clubs, the plurality of increasing numbered iron clubs each having a shaft and a golf club head, the golf club head positioned on an end of the shaft, the golf club head of each iron golf club comprising:

a striking face that provides a contact area for engaging a golf ball;

a rear cavity opposite the striking face;

a bridge member extending across the rear cavity; and

a weight positioning assembly integral to the bridge member, the weight positioning assembly including:

a rail, the rail extending from a front surface through to a back surface, and

a weight movably connected to the rail, the weight being movable along the rail to vary a position of a center of gravity of the golf club head in a first direction with respect to the striking face.

9. The set of iron golf clubs of claim 8 , wherein the weight comprises a weight chip.

10. The set of iron golf clubs of claim 8 , wherein the weight is interchangeable with one of a plurality of alternate weights.

11. The set of iron golf clubs of claim 10 , wherein at least one of the alternate weights has a different mass than the weight.

13. A set of iron golf clubs, the set of iron golf clubs comprising:

a plurality of increasing numbered iron golf clubs, the plurality of increasing numbered iron clubs each having a shaft and a golf club head, the golf club head positioned on an end of the shaft, the golf club head of each iron golf club comprising:

a heel;

a toe;

a body extending between the toe and the heel, the body comprising:

a striking face, the striking face having a contact area for engaging a golf ball;

a rear cavity, the rear cavity opposite the striking face;

a bridge member extending across the rear cavity, the bridge member having a front surface and a back surface;

a rail formed in the bridge member, the rail extending from the front surface through to the back surface; and

a weight, the weight shaped to engage and slide along the rail to vary the position of the center of gravity of the golf club head with respect to the striking face.
