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.

a second bracing member connected to the interior surface of the head on the upper sole portion, the second bracing member comprising a plurality of second trusses connected to a plurality of second connection points spaced from each other on the interior surface, with each second truss extending inwardly into the interior cavity from the second connection point thereof, such that the plurality of second trusses form a second bridge portion extending inwardly into the interior cavity and being spaced from the interior surface, wherein the first bracing member and the second bracing member are separate from each other; and

wherein all of the plurality of second trusses are in the form of legs extending downward and outward from a second juncture;

wherein the first bracing member and the second bracing member are spaced away from the strike face;

wherein the first plurality of connection points and the second plurality of connection points are discrete points.

2. The golf club head of claim 1, further comprising a third bracing member, and a fourth bracing member, both of which are positioned on the lower crown surface, separate from one another and the first bracing member.

3. The golf club head of claim 2, wherein the first, third, and fourth bracing members are symmetrically aligned with respect to the body.

4. The golf club head of claim 2, wherein the first, third, and fourth bracing members are aligned in a row extending in a front-to-rear direction on the club head.

5. The golf club head of claim 2, wherein the third bracing member comprising a plurality of third trusses connected to a plurality of third connection points spaced from each other on the interior surface, with each third truss extending inwardly into the interior cavity from the third connection point thereof, such that the plurality of third trusses form a third bridge portion extending inwardly into the interior cavity and being spaced from the interior surface.

6. The golf club head of claim 2, wherein the fourth bracing member comprising a plurality of fourth trusses connected to a plurality of fourth connection points spaced from each other on the interior surface, with each fourth truss extending inwardly into the interior cavity from the fourth connection point thereof, such that the plurality of fourth trusses form a fourth bridge portion extending inwardly into the interior cavity and being spaced from the interior surface.

7. The golf club head of claim 2, further comprising a fifth bracing member, and a sixth bracing member, both of which are positioned on the upper sole surface, separate from one another and the second bracing member.

8. The golf club head of claim 7, wherein the second, fifth, and sixth bracing members are symmetrically aligned with respect to the body.

9. The golf club head of claim 7, wherein the second, fifth, and sixth bracing members are aligned in a row extending in a front-to-rear direction on the club head.

10. The golf club head of claim 7, wherein the fifth bracing member comprising a plurality of fifth trusses connected to a plurality of fifth connection points spaced from each other on the interior surface, with each fifth truss extending inwardly into the interior cavity from the fifth connection point thereof, such that the plurality of fifth trusses form a fifth bridge portion extending inwardly into the interior cavity and being spaced from the interior surface.

11. The golf club head of claim 7, wherein the sixth bracing member comprising a plurality of sixth trusses connected to a plurality of sixth connection points spaced from each other on the interior surface, with each sixth truss extending inwardly into the interior cavity from the sixth connection point thereof, such that the plurality of sixth trusses form a sixth bridge portion extending inwardly into the interior cavity and being spaced from the interior surface.

12. The golf club head of claim 11, wherein the plurality of sixth trusses define a generally triangular shape with the interior surface.

13. 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 body joined to the face around peripheral edges of the face and extending rearwardly from the face, such that the body and the face combine to define an interior cavity surrounded by an interior surface of the head, the body having a crown and a sole, with the crown having an upper crown surface forming at least a portion of a top of the head and a lower crown surface opposite the upper crown surface and the sole having a bottom sole surface configured to confront a playing surface and an upper sole surface opposite the bottom sole surface; and

a bracing member connected to the interior surface of the head, the bracing member comprising at least a first truss having a first end connected to the lower crown surface and spaced near the face and a second truss having a second end connected to the lower crown surface proximate the top edge, with the first truss extending inwardly into the interior cavity from the first end and the second truss extending inwardly into the interior cavity from the second end, such that the plurality of first and second trusses at least partially form a bridge portion extending inwardly into the interior cavity and being spaced from the interior surface; and
