Abstract

A ball striking device has a face with a striking surface and a body extending rearwardly from the outer periphery of the face. A channel crosses a centerline of the sole, and includes a trough defined between front and rear edges and extending in a heel-toe direction. The device further has internal interconnection structure for connection of a shaft to the head. A bore or access opening is provided to access the interconnecting structure. The rear edge of the first portion of the channel in its entirety is positioned more proximate to the face than to a rear of the golf club head. The access opening and the front edge of the channel at the centerline of the sole are spaced from the outer periphery of the face by equal distances, and a part of the channel passes between the access opening and the rear of the golf club head.

First claim

What is claimed is:

1. A golf club head comprising:
a face having a striking surface configured for striking a ball, the face having an outer periphery;
a body connected to the face and extending rearwardly from the outer periphery of the face, wherein the face and the body define an interior cavity, the body having a sole configured to face a playing surface, a crown opposite the sole, a heel, and a toe;
an internal interconnection structure adapted for connection of a shaft to the heel of the body in an adjustable configuration;
an access opening extending through the sole and providing access to the internal interconnection structure; and
an inwardly recessed channel extending across at least a portion of the sole of the body, wherein the channel comprises an inwardly recessed trough and has a heel portion proximate to the heel and proximate to the face and a toe portion proximate to the toe and proximate to the face, a first portion of the channel being defined between a front edge and a rear edge extending between the heel portion and the toe portion in a heel-toe direction and including the heel portion and the toe portion, wherein the rear edge of the first portion of the channel in its entirety is positioned more proximate to the face than to a rear of the golf club head,
wherein the channel crosses a centerline of the sole, wherein the access opening and the front edge of the channel at the centerline of the sole are spaced from the outer periphery of the face by equal distances, and wherein a part of the channel passes between the access opening and the rear of the golf club head along a virtual vertical plane passing through the access opening and parallel to a virtual vertical plane oriented perpendicular to a center of the striking surface.

2. The golf club head of claim 1 , wherein the golf club head has at least one weight member located on the sole.

3. The golf club head of claim 2 , wherein the at least one weight member is releasable by having a threaded connection.

4. The golf club head of claim 1 , wherein the channel further has a center portion between the heel portion and the toe portion, and wherein a width of the channel defined between the front and rear edges is greater proximate the center portion as compared to at least one of the heel portion and the toe portion.

5. The golf club head of claim 1 , wherein the channel further has a center portion between the heel portion, and the toe portion, and wherein at least one of the front and rear edges of the channel is spaced further from the outer periphery of the face at the center portion compared to the heel portion and the toe portion.

6. The golf club head of claim 1 , wherein the access opening intersects the channel.

7. A golf club head comprising:
a face having a striking surface configured for striking a ball, the face having an outer periphery;
a body connected to the face and extending rearwardly from the outer periphery of the face, wherein the face and the body define an interior cavity, the body having a sole configured to face a playing surface, a heel, and a toe, with the sole having a centerline extending in a front-to-rear direction;
an internal interconnection structure adapted for connection of a shaft to the heel of the body;
an access opening extending through the sole and providing access to the internal interconnection structure;
an inwardly recessed channel extending across at least a portion of the sole of the body, such that the channel crosses the centerline of the sole, wherein the channel comprises an inwardly recessed trough and has a heel portion proximate to the heel and proximate to the face and a toe portion proximate to the toe and proximate to the face, a first portion of the channel being defined between a front edge and a rear edge extending between the heel portion and the toe portion transverse to the centerline and including the heel portion and the toe portion of the sole, wherein the rear edge of the first portion of the channel in its entirety is positioned more proximate to the face than to a rear of the golf club head, wherein the access opening and the front edge of the channel at the centerline of the sole are spaced from the outer periphery of the face by equal distances, and wherein a part of the channel passes between the access opening and the rear of the golf club head along a virtual vertical plane passing through the access opening and parallel to a virtual vertical plane oriented perpendicular to a center of the striking surface; and
a weight member located on the sole and positioned rearwardly from the rear edge of the channel.

8. The golf club head of claim 7 , wherein the weight member is releasable by having a threaded connection.

9. The golf club head of claim 7 , wherein the channel further has a center portion between the heel portion, and the toe portion, and wherein a width of the channel defined between the front and rear edges is greater proximate the center portion as compared to at least one of the heel portion and the toe portion.

10. The golf club head of claim 7 , wherein the channel further has a center portion between the heel portion, and the toe portion, and wherein at least one of the front and rear edges of the channel is spaced further from the outer periphery of the face at the center portion compared to the heel portion and the toe portion.

11. The golf club head of claim 7 , wherein the access opening intersects the channel.

12. A golf club head comprising:
a face having a striking surface configured for striking a ball, the face having an outer periphery;
a body connected to the face and extending rearwardly from the outer periphery of the face, wherein the face and the body define an interior cavity, the body having a sole configured to face a playing surface, a heel, and a toe, with the sole having a centerline extending in a front-to-rear direction;
an internal interconnection structure adapted for connection of a shaft to the heel of the body;
an access opening extending through the sole and providing access to the internal interconnection structure; and
an inwardly recessed channel extending across at least a portion of the sole of the body, such that the channel crosses the centerline of the sole, wherein the channel comprises an inwardly recessed trough and has a heel portion proximate to the heel and proximate to the face and a toe portion proximate to the toe and proximate to the face, a first portion of the channel being defined between a front edge and a rear edge extending between the heel portion and the toe portion transverse to the centerline and including the heel portion and the toe portion of the sole, wherein the rear edge of the first portion of the channel in its entirety is positioned more proximate to the face than to a rear of the golf club head, wherein the access opening and the front edge of the channel at the centerline of the sole are spaced from the outer periphery of the face by equal distances, and wherein the channel protrudes into the interior cavity, and wherein a part of the channel passes between the access opening and the rear of the golf club head along a virtual vertical plane passing through the access opening and parallel to a virtual vertical plane oriented perpendicular to a center of the striking surface.

13. The golf club head of claim 12 , wherein the golf club head has at least one weight member located on the sole.

14. The golf club head of claim 13 , wherein the at least one weight member is releasable by having a threaded connection.

15. The golf club head of claim 13 , wherein
the at least one weight memb
