Golf club and golf club head structures

1. A golf club head comprising:

a body including a ball striking surface, a crown, a sole, one or more sidewalls, a rear, a toe portion, and a heel portion;

the body further comprising a first leg extending away from the ball striking face towards the rear of the golf club head and a second leg extending away from the ball striking face towards the rear of the golf club head to define a v-shaped void;

wherein the first leg comprises a first side and the second leg comprises a second side:

wherein the first side and the second side are in a generally confronting relation, forming sides of the v-shaped void:

wherein the first side and the second side each provide a generally flat surface:

wherein:

the first leg and the second leg reside below the crown of the golf club head;

the first leg of the body defines a first passageway to receive a first weight;

the second leg of the body defines a second passageway to receive a second weight; and

the first leg and the second leg converge towards one another to meet at an interface area;

wherein the first side and the second side converge toward the interface area;

wherein the first passageway of the first leg defines a track that allows the first weight to be moveable along the track:

wherein the second passageway of the second leg defines a track that allows the second weight to be moveable along the track:

wherein each of the first weight and the second weight have a first position near the interface area, and each of the first weight and the second weight are configured to slide outward from their respective first positions toward rear corners of the golf club head; and

wherein the movement of one weight causes a corresponding movement of the other weight.

2. The golf club head of claim 1 , wherein the first weight and the second weight have the same weighting characteristics.

3. The golf club head of claim 1 , wherein the first weight and the second weight have different weighting characteristics.

4. The golf club head of claim 1 , wherein the v-shaped void extends substantially through the golf club head in a crown-to-sole direction.

5. The golf club head of claim 1 , wherein the v-shaped void opens towards the rear of the golf club head.

6. The golf club head of claim 1 , wherein the v-shaped void extends from a rear edge of the golf club head, inward, towards a central region of the golf club head and towards the ball striking surface.

7. The golf club head of claim 1 , wherein the v-shaped void is visible when the golf club head is viewed from the sole, but the v-shaped void is not visible when viewed from the crown of the golf club head.

8. The golf club head of claim 1 , wherein the golf club head is a driver-type club head.

9. A golf club head comprising:

a body comprising a ball striking surface, a cover defining a crown portion, a sole, one or more sidewalls, a rear, a toe portion, and a heel portion;

the body further comprising a first leg extending away from the ball striking face and a second leg extending away from the ball striking face to define a v-shaped void;

wherein the first leg comprises a first side and the second leg comprises a second side;

wherein the first side and the second side are in a generally confronting relation, forming sides of the v-shaped void;

wherein the first side and the second side each provide a generally flat surface; and

wherein:

the first leg and the second leg reside below the cover of the golf club head;

a portion of the first leg of the body defines a first passageway to receive a first weight;

a portion of the second leg of the body defines a second passageway to receive a second weight; and

the first leg and the second leg converge towards one another to meet at an interface area;

wherein the first side and the second side converge toward the interface area;

wherein the first passageway of the first leg defines a track that allows the first weight to be moveable along the track:

wherein the second passageway of the second leg defines a track that allows the second weight to be moveable along the track:

wherein each of the first weight and the second weight have a first position near the interface area, and each of the first weight and the second weight are configured to slide outward from their respective first positions toward rear corners of the golf club head; and

wherein the movement of one weight causes a corresponding movement of the other weight.

10. The golf club head of claim 9 , wherein the first weight and the second weight have the same weighting characteristics.

11. The golf club head of claim 9 , wherein the first weight and the second weight have different weighting characteristics.

12. The golf club head of claim 9 , wherein the v-shaped void extends substantially through the golf club head in a top-to-bottom direction.

13. The golf club head of claim 9 , wherein the v-shaped void opens towards the rear of the golf club head.

14. The golf club head of claim 9 , wherein the v-shaped void extends from a rear edge of the golf club head, inward, towards a central region of the golf club head and towards the ball striking surface.

15. The golf club head of claim 9 , wherein the v-shaped void is visible when the golf club head is viewed from the sole, but the v-shaped void is not visible when viewed from the crown portion of the golf club head.

16. The golf club head of claim 9 , wherein the golf club head is a driver-type club head.
