Abstract

A ball striking device, such as an iron-type golf club head, includes a face having a ball striking surface and a body connected to the face. The body has a sole surface extending rearward from a leading edge of the face, and a toe surface extending rearward from a toe edge of the face. The sole surface configured to confront the playing surface. The iron-type club head may have an elongated channel extending from a heel side in the sole member to an end point within the toe surface. The elongated channel is recessed from the sole surface and toe surfaces and is spaced from the leading and toe edges of the face. The iron-type club head may also have a plurality of weighting elements that are adjustable by the user.

First claim

What is claimed is:

1. An iron-type golf club head, comprising:
a face comprising a substantially flat ball striking surface with a plurality of grooves,
a rear surface opposite the ball striking surface,
a body comprising a hosel, a heel side, a toe side, a toe surface, a top surface, and a sole surface, and
an elongated channel located in the sole surface being spaced backward from a leading edge, the elongated channel being recessed from the sole surface,
wherein the elongated channel has a depth of recession from the sole surface and has a length defined between a first end located on the heel side of the sole surface and extending toward the toe side to a second end,
wherein the elongated channel has a forward wall, a rear wall, and an upper wall,
wherein the upper wall has a curved shape,
wherein a plurality of weighting elements are positioned on the sole surface and the toe surface, and
wherein the plurality of weighting elements are separate from and positioned rearward of the elongated channel.

2. The iron-type golf club head of claim 1 , wherein the second end of the elongated channel is located on the toe surface, and wherein the second end of the elongated channel is located within a range of 40 percent to 70 percent of a maximum club head height.

3. The iron-type golf club head of claim 1 , wherein the elongated channel is generally parallel to the leading edge of the face.

4. The iron-type golf club head of claim 1 , wherein the iron-type golf club head contains a hollow interior.

5. The iron-type golf club head of claim 1 , wherein at least one of the plurality of weighting elements is oriented along an axis substantially perpendicular to the sole surface.

6. The iron-type golf club head of claim 1 , wherein at least one of the plurality of weighting elements is oriented along an axis substantially perpendicular to the toe surface.

7. The iron-type golf club head of claim 1 , wherein the plurality of weighting elements comprises at least one weighting element positioned on the toe surface, at least one weighting element positioned near a center of the sole surface, and at least one weighting element positioned near the heel side of the sole surface.

8. The iron-type golf club head of claim 1 , wherein the plurality of weighting elements comprises a first weighting element made of a first material and a second weighting element made of a second material.

9. An iron-type golf club head of claim 1 , wherein the iron-type golf club head has an overall sole thickness within a range between 13 mm and 31 mm.

10. An iron-type golf club head, comprising:
a face comprising a substantially flat ball striking surface with a plurality of grooves,
a body comprising a hosel, a heel side, a toe side, a toe surface, a top surface, and a sole surface, and
an elongated channel located in the sole surface and the toe surface and being spaced backward from a leading edge, the elongated channel being recessed from the sole surface and the toe surface,
wherein the elongated channel has a depth of recession from the sole surface and the toe surface, and a length defined between a first end located in the heel side and a second end located on the toe surface,
wherein the elongated channel has a forward wall, a rear wall, and an upper wall,
wherein the upper wall has a curved shape,
wherein a plurality of weighting elements are positioned on the sole surface and the toe surface with at least one of the plurality of weighting elements oriented along an axis substantially perpendicular to the sole surface,
wherein the iron-type golf club contains a hollow interior, and
wherein the plurality of weighting elements are separate from and positioned rearward of the elongated channel.

11. The iron-type golf club head of claim 10 , wherein the iron-type golf club head has an overall sole thickness within a range between 13 mm and 31 mm.

12. The iron-type golf club head of claim 10 , wherein at least one of the plurality of weighting elements is oriented along an axis substantially perpendicular to the toe surface.

13. The iron-type golf club head of claim 10 , wherein the plurality of weighting elements comprises a first weighting element made of a first material and a second weighting element made of a second material.

14. The iron-type golf club head of claim 13 , wherein the plurality of weighting elements further comprises a third weighting element wherein the first weighting element, the second weighting element, and the third weighting element are cylindrically shaped and have the same volume.

15. An iron-type golf club head, comprising:
a face comprising a substantially flat ball striking surface with a plurality of grooves,
a body comprising a hosel, a heel side, a toe side, a toe surface, a top surface, and a sole surface,
a rear body member enclosing a hollow interior,
an elongated channel located in the sole surface and the toe surface and being spaced backward from a leading edge, the elongated channel being recessed from the sole surface and the toe surface,
a first weighting element,
a second weighting element, and
a third weighting element,
wherein the elongated channel has a depth of recession from the sole surface and the toe surface and a length defined between a first end located in the heel side and a second end located on the toe surface,
wherein the elongated channel has a forward wall, a rear wall, and an upper wall,
wherein the upper wall has a curved shape,
wherein the first weighting element, the second weighting element, and the third weighting element are removable,
wherein the iron-type golf club head has an overall sole thickness within a range between 13 mm and 31 mm, and
wherein the plurality of weighting elements are separate from and positioned rearward of the elongated channel.

16. The iron-type golf club head of claim 15 , wherein the first weighting element has a first axis oriented substantially perpendicular to the toe surface, the second weighting element has a second axis oriented substantially perpendicular to the sole surface, and the third weighting element has a third axis oriented substantially perpendicular to the sole surface.

17. The iron-type golf club head of claim 15 , wherein the first weighting element is made of a first material and the second weighting element is made of a second material, and wherein the first material is different than the second material.

18. The iron-type golf club head of claim 15 , wherein the second end of the elongated channel is located within a range of 40 percent to 70 percent of a maximum club head height.
