Abstract

A head for a ball striking device includes a bracing member connected to an upper sole surface located on the sole of the body opposite the bottom sole surface. The bracing member includes a first end connected to a first point on the upper sole surface, a second end connected to a second point on the upper sole surface spaced from the first point, and a bridge portion extending between the first and second ends. The bridge portion extends upward from the upper sole surface and is spaced from the upper sole surface. The bridge portion may be formed by one or more trusses, and may define a generally triangular shape in one embodiment. The first and second ends may be connected to the upper sole surface using a variety of techniques, e.g., welding or other integral joining technique, integral forming, adhesive or other bonding material, or other technique. The location of the bracing member may be determined using a modal analysis to determine a maximum displacement region.

First claim

What is claimed is:

1 . A golf club head comprising:
a face having an outer surface configured for striking a ball and a rear surface opposite the outer surface; a front, a rear, a toe, and a heel; a body joined to the face around peripheral edges of the face and extending rearwardly from the face, the body including a club head crown portion and a club head sole portion, wherein the body defines an interior cavity surrounded by an interior surface; and a bracing member positioned within the interior cavity and including a spine member spaced from a portion of the interior surface, a first leg having a first end contacting the interior surface and a second end connected to the spine member, a second leg having a first end spaced from the first end of the first leg and contacting the interior surface, and a second end connected to the spine member, a third leg having a first end spaced from the first end of the first leg and from the first end of the second leg and contacting the interior surface, and a second end connected to the spine member, and a fourth leg having a first end spaced from the first end of the first leg and from the first end of the second leg and from the first end of the third leg and contacting the interior surface, and a second end connected to the spine member, wherein the spine extends from the toe towards the heel of the golf club head.

2 . The golf club head of claim 1 , wherein the first ends of each of the first, second, third, and fourth legs contact the interior surface adjacent the sole portion;
wherein the bracing member connects the first, second, third and fourth legs.

3 . The golf club head of claim 1 , wherein the spine member includes a first end and a second end and an elongated body extending therebetween.

4 . The golf club head of claim 3 , further including a fifth leg having a first end contacting the interior surface and a second end connected to the first end of the spine member.

5 . The golf club head of claim 4 , further including a sixth leg having a first end contacting the interior surface and a second end connected to the second end of the spine member.

6 . The golf club head of claim 1 , wherein the first ends of the first and second legs are positioned to one side of the spine member and the first ends of the third and fourth legs are positioned to another side of the spine member.

7 . The golf club head of claim 1 , wherein the first ends of each of the first, second, third, and fourth legs contact the interior surface adjacent the crown portion.

8 . The golf club head of claim 1 , wherein the spine member, the first leg, the second leg, the third leg, and the fourth leg are all integrally formed as one piece.

9 . The golf club head of claim 8 , wherein the bracing member is constructed of a polymer.

10 . The golf club head of claim 1 , wherein the spine member, the first leg, the second leg, the third leg, and/or the fourth leg is constructed from titanium.

11 . The golf club head of claim 1 , wherein the spine member includes a first end and a second end and an elongated linear body extending therebetween.

12 . The golf club head of claim 11 , wherein the second end of the first leg and the second end of the third leg are located the same distance from the first end of the spine member.

13 . The golf club head of claim 12 , wherein the first leg and the third leg form a triangular shape and wherein the second leg and the fourth leg form a triangular shape.

14 . The golf club head of claim 1 , wherein the spine member includes a first end and a second end and a curvilinear body extending therebetween.

15 . The golf club head of claim 1 , wherein the spine member includes a first end and a second end and a body comprising a first segment and a second segment,
wherein the first segment is angled relative to the second segment.

16 . The golf club head of claim 1 , wherein the first leg and the third leg have a combined designed mass greater than a combined designed mass of the second leg and the fourth leg.

17 . The golf club head of claim 1 , wherein the interior surface is an interior surface of the club head sole portion;
wherein the bracing member comprises a length extending across at least 50% of a largest width of the club head sole portion.

18 . The golf club head of claim 1 , wherein the bracing member comprises a weight ranging from 1 gram to 6 grams.

19 . The golf club head of claim 1 , wherein the spine comprises a cross-sectional shape with a spine height that is at least two times a spine width.

20 . The golf club head of claim 1 , wherein the spine is spaced from the interior surface; wherein the spine is spaced from the interior surface a distance in a range of 1 mm to 4 mm.
