Abstract

Golf club heads include a golf club head body, a ball striking face, and a shaft engaging member configured to engage a golf club shaft with the golf club head body. Additionally, the shaft engaging member may be configured to engage the golf club head body and the shaft below a center of gravity of the golf club head, and/or the shaft engaging member may have rotational locking structure that can be locked in a plurality of positions. Further, the golf club head may include a face member and a rear member, where the rear member is configured to transfer energy and/or momentum to the face member, particularly on off-center hits.

Dependent claims

A golf club head comprising:

an iron-type golf club head body having connecting structure, the golf club head body comprising:
a face member including a face having a striking surface configured for striking a ball and a rear side opposite the striking surface of the face, the face member having a heel edge and a toe edge;
a rear member joined to the rear side of the face member, the rear member having a heel edge and a toe edge;
and
a first connection member connecting the rear side of the face member to the rear member at a connection point located toward a center of the face from the heel edge and the toe edge of the face member and located toward a center of the rear member from the heel edge and the toe edge of the rear member,
wherein the face member is spaced from the rear member between the first connection member and the heel edge of the face member and between the first connection member and the toe edge of the face member, and wherein the connection point comprises a joint that permits the rear member to transfer momentum to the face member upon an impact of the ball on the striking surface;
and
a shaft engaging member engaged with the connecting structure of the golf club head body, wherein the shaft engaging member is configured to be engaged with a golf club shaft to connect the shaft to the golf club head body,
wherein the connecting structure comprises a passage extending into the golf club head body from a heel side of the golf club head body, wherein the face member and the rear member combine to define the passage, and wherein the shaft engaging member is received in the passage to engage the connecting structure.

A golf club head comprising:

an iron-type golf club head body comprising:
a face member including a face having a striking surface configured for striking a ball and a rear side opposite the striking surface of the face, the face member having a heel edge and a toe edge, and wherein the face member has a first engaging surface;
a rear member joined to the rear side of the face member, the rear member having a heel edge and a toe edge, wherein the rear member has a second engaging surface;
a first connection member connecting the rear side of the face member to the rear member at a connection point located toward a center of the face from the heel edge and the toe edge of the face member and located toward a center of the rear member from the heel edge and the toe edge of the rear member, wherein the face member is spaced from the rear member between the first connection member and the heel edge of the face member and between the first connection member and the toe edge of the face member, and wherein the first connection member comprises a pin on the rear side of the face member that is received in a receiver on the rear member to form a joint that permits the rear member to transfer momentum to the face member upon an impact of the ball on the striking surface;
and
a resilient member separating the rear member from the rear side of the face member, wherein the resilient member engages the rear member and the rear side of the face member and is configured to transfer momentum between the face member and the rear member;
wherein the first engaging surface and the second engaging surface combine to define a passage extending into the golf club head body and forming at least a portion of a connecting structure of the golf club head body;
and
