Abstract

An iron the golf club head with an improved anchor-back hosel construction having an upper shaft socket section and a lower section, wherein the lower section of the hosel, in various shapes, emanates from the back of the club head, adjacent the rear of the club face and the heel portion. The hosel extends beyond and away from the heel portion having an upper shaft socket section angularly disposed to be offset, set in-line with, or behind the leading edge of the club face. A longitudinal axis through the upper shaft socket section, if extended, is offset from and non-intersecting with any portion of the club head body.

and a hosel permanently and non-rotatably fixed to said club head body, said hosel having an upper shaft-socket section for connection to a golf club shaft, said upper shaft-socket section being generally cylindrical in shape and extending upwardly at an angle relative to said longitudinal axis of the golf club head body, and a lower section connected to said upper section and formed at an angle with said upper shaft-socket section, said lower section originating from the rear surface of said club head body and extending in the same general direction as said club head longitudinal axis;

said upper shaft-socket section of said hosel having a hosel longitudinal axis therethrough, an extension of which is offset from and located in a toe to heel direction outside of the outer periphery of said club head body;

said lower section of said hosel being elongated in a heel to toe direction, extending within the outer periphery of the club head body, and being connected to and overlaying at least a portion of said rear surface.

2. The golf club head of claim 1 wherein the forwardmost portion of said hosel is behind, in a front face to rear surface direction, the leading edge of said club face.

3. The golf club head of claim 1 wherein the forwardmost portion of said hosel is ahead, in a front face to rear surface direction, of the leading edge of said club face.

4. The golf club head of claim 1 wherein the forwardmost portion of said hosel is in line, in a front face to rear surface direction, with the leading edge of said club face.

5. The golf club head of claim 1 wherein the entire upper shaft-socket section of said hosel is offset from and located in a toe and heel direction beyond the outer periphery of said club head body.

6. The golf club head of claim 5 wherein said lower portion includes a recess on a frontmost portion thereof, said recess being located between said ball striking face adjacent said heel and said upper shaft-socket section of said hosel.

7. The golf club head of claim 1 wherein said upper section and said lower section of said hosel combine to form a generally L-shaped hosel.

8. The golf club head of claim 1 wherein said lower section of said hosel extends along said longitudinal axis of said golf club head body.

9. The golf club head of claim 1-wherein said lower section of said hosel has a height in a top to bottom direction of at least 3/8 inch.

10. The golf club head of claim 1 wherein said lower section of said hosel extends outwardly from the rear surface of the club head by at least 1/8 inch.

11. The golf club head of claim 1 further comprising a weight member which is connected to and extends from the lower section of the hosel, said weight member extending in a heel to toe direction to at least the center of gravity of the club head body and projecting rearwardly from the rear surface of the club face.

12. The golf club head of claim 11 wherein said weight member is symmetrically positioned about the longitudinal axis of the club head.

13. The golf club head of claim 11 wherein said weight member extends the entire length of said cavity in a heel to toe direction.

14. The golf club head of claim 11 wherein said weight member is T-shaped, including a first element formed in a heel to toe direction and a second element perpendicular thereto proximate said center of gravity in a direction between upper and lower surfaces of said club head.

15. The golf club head of claim 11 wherein said weight member is a Y-shaped projection extending in a heel to toe direction on the rear surface of said club head.

16. The golf club head of claim 11 wherein said weight member is a loop extending around an inner periphery of a cavity formed on said rear club face.

17. The golf club head of claim 11 wherein said weight member is a loop extending partway into a cavity formed on said rear surface club face.

18. The golf club head of claim 11 wherein said weight member includes a first longitudinal weight element extending in a heel to toe direction along the longitudinal axis of the club head and second weight element located approximately opposite the center of gravity of said club head.

19. The golf club head of claim 1, wherein the lower shaft-socket section extends beyond the heel in a toe to heel direction.

20. An iron type golf club head for hitting a golf ball comprising:

a golf club head body having a heel, a toe, a bottom sole, a planar, lofted ball striking face having a loft greater than 12 degrees, the ball striking face intersecting with a forwardmost progression of said bottom sole to define a leading edge of the ball striking face of said golf club, a club head longitudinal axis through said club head body in a heel to toe direction, a rear surface, and an outer periphery of said club head defined by an most outward exterior, front surfaces of said heel, toe and ball striking face;

and a hosel permanently and non-rotatably fixed to said club head body, said hosel having an upper shaft-socket section for connection to a golf club shaft, said upper shaft-socket section being generally cylindrical in shape and extending upwardly at an angle relative to said longitudinal axis of the golf club head body and a lower section connected to said upper section and formed at an angle with said upper shaft-socket section, said lower section originating from the rear surface of said club head body and extending in the same general direction as said club head longitudinal axis;

said upper shaft-socket section of said hosel having a hosel longitudinal axis therethrough, an extension of which is offset from and located in a toe to heel direction outside of the outer periphery of said club head body;

said lower section of said hosel being elongated in a heel to toe direction, extending within the outer periphery of the club head body, and being connected to and overlaying at least a portion of said rear surface;

the forwardmost portion of said hosel being behind, in a front face to rear direction, the leading edge of said club face.

21. The golf club head of claim 20 wherein the entire upper shaft -socket section of said hosel is offset from and located in a toe to heel direction beyond the outer periphery of said club head body.

22. The golf club head of claim 21 wherein said lower portion includes a recess on a frontmost portion thereof, said recess being located between said ball striking face adjacent said heel and said upper shaft-socket section of said hosel.
