Abstract

Golf club heads (e.g., drivers, fairway woods, wood-type hybrid clubs, or the like) according to at least some example aspects of this invention include a striking face and a rear portion opposite the striking face, the rear portion defining an opening to an interior cavity. A rear body member configured to be inserted into the opening is engaged with the rear portion of the club head. The rear body member may include multiple rear body parts that may be removable and/or interchangeable to permit flexibility in controlling the weight distribution of the golf club head.

Claims

1. A golf club head comprising:

a club head body made from one or more parts, the club head body including a heel portion, a toe portion, a top portion, a sole portion, and a striking face, wherein the club head body defines an interior cavity and further defines an opening to the interior cavity, wherein the opening is located in a rear portion of the club head body away from the striking face and is defined by an upper surface adjacent the top portion and a lower surface adjacent the sole portion;

a support beam extending across the opening from the upper surface to the lower surface in a substantially vertical orientation, wherein the support beam is centrally located within the opening; and

a rear body member removably engageable with the club head body, configured to extend beyond a perimeter of the club head body, and configured to at least partially cover the opening to the interior cavity of the club head body,

wherein the rear body member forms a portion of the sole portion of the golf club head and the rear body member includes at least one receptacle configured to receive a weight member, wherein the weight member is removably engageable with the rear body member.

2. The golf club head of claim 1, wherein the support beam is used to at least partially secure the rear body member to the club head body.

3. The golf club head of claim 1, wherein the club head body is made of a titanium alloy.

4. The golf club head of claim 1, wherein the rear body is made of a polymeric material.

5. The golf club head of claim 1, wherein the club head body and rear body member have corresponding surfaces to at least partially secure the rear body member to the club head body.

6. The golf club head of claim 1, wherein the support beam and the rear body member comprise a means of being secured and released from each other selected from the group consisting of:

mechanical connectors, friction fits, clamps, clasps, cam structures, retaining members with groove or opening structures, and spring loaded mechanisms.

7. The golf club head of claim 1, wherein:

the club head further comprises at least one fastening member;

the support beam comprises at least one aperture for receiving the at least one fastening member;

the rear body member comprises at least one mounting hole for receiving the at least one fastening member; and

the at least one fastening member is removably engageable with the support beam and the rear body member.

8. A golf club head comprising:

a club head body made from one or more parts, the club head body including a heel portion, a toe portion, a top portion, a sole portion, and a striking face, wherein the club head body defines an interior cavity and further defines an opening to the interior cavity, wherein the opening is located in a rear portion of the club head body away from the striking face and is defined by an upper surface adjacent the top portion and a lower surface adjacent the sole portion; and

a rear body member engageable with the club head body and is configured to at least partially cover the opening to the interior cavity in the club head body, the rear body member including at least one receptacle configured to receive a weight member, wherein the weight member is removably engageable with the rear body member,

wherein the club head body includes a plurality of support beams, and wherein the plurality of support beams extend across the opening from the upper surface to the lower surface of the opening.

9. The golf club head of claim 8, wherein plurality of support beams are used to at least partially secure the rear body member to the club head body.

10. The golf club head of claim 8, wherein the club head body is made of a titanium alloy.

11. The golf club head of claim 8, wherein the rear body is made of a polymeric material.

12. The golf club head of claim 8, wherein the club head body and rear body member have corresponding surfaces to at least partially secure the rear body member to the club head body.

13. A golf club head comprising:

a club head body made from one or more parts, including a heel portion, a toe portion, a top portion, a sole portion, and a striking face, wherein the club head body defines an interior cavity and further defines an opening to the interior cavity,

wherein the opening is located in a rear portion of the club head body away from the striking face and is defined by an upper surface adjacent the top portion and a lower surface adjacent the sole portion,

wherein the club head body includes a support beam, and wherein the support beam is located at a central area of the opening to the interior cavity of the club head body and extends across the opening from the upper surface to the lower surface in a substantially vertical orientation; and

a rear body member forming a portion of the sole portion of the golf club head and made from a polymeric material including at least one receptacle configured to receive a removable weight member,

wherein the rear body member is removably engageable with the club head body and is configured to at least partially cover the opening to the interior cavity in the club head body, and wherein the club head body and the rear body member have corresponding surfaces to at least partially secure the rear body member to the club head body and at least one surface of the support beam comprises at least one of the corresponding surfaces.

14. The golf club head of claim 13, wherein the club head body is made of a titanium alloy.

15. The golf club head of claim 13, wherein the rear body member is formed from an injection molding process.

16. The golf club head of claim 13, wherein the support beam and the rear body member comprise a means of being secured and released from each other selected from the group consisting of:

mechanical connectors, friction fits, clamps, clasps, cam structures, retaining members with groove or opening structures, and spring loaded mechanisms.

17. The golf club head of claim 13, wherein:

the club head further comprises at least one fastening member;

the support beam comprises at least one aperture for receiving the at least one fastening member;

the rear body member comprises at least one mounting hole for receiving the at least one fastening member; and

the at least one fastening member is removably engageable with the support beam and the rear body member.
