Abstract

A golf club (40) having a club head (42) with a face component (60), an aft body (61), and a sound modifying sole and crown design is disclosed herein. The face component, which may be composed of a metal material, (60) has a striking area portion (72) and a return portion (74). The aft-body (61), which may be composed of a non-metal material such as composite or thermoplastic material, is composed of a crown portion (62) and a sole portion (64). The sound modifying design, which may include deep pockets or pillars extending from the sole portion (64) to the crown portion (62), alters the sound of the golf club head (42) when it impacts a golf ball.

Claims

wherein the rear section comprises a sole side, a crown side, a heel side, and a toe side;

wherein the crown and the sole each have a periphery and are connected to one another at their peripheries;

wherein the crown and sole are connected to one another at one or more locations spaced inward from their respective peripheries to form at least one deep pocket; and

wherein an interior surface of the crown is visible through the at least one deep pocket.

2. The golf club head of claim 1, wherein the crown is composed of a composite material.

3. The golf club head of claim 1, wherein the sole is composed of a composite material.

4. The golf club head of claim 1, wherein the face portion is composed of a titanium material.

5. The golf club head of claim 1, further comprising a ribbon disposed between and connected to the crown and the sole at their respective peripheries.

14. A golf club head comprising

a face component;

a composite crown comprising interior and exterior surfaces; and

a composite sole comprising at least one deep pocket;

wherein the at least one deep pocket comprises interior and exterior surfaces; and

wherein a portion of the interior surface of the at least one deep pocket contacts a portion of the interior surface of the composite crown.
