First Claim
1. An iron-type golf club head 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, wherein a rear cavity is defined on the rear side of the face member;
a rear member connected to the rear side of the face member, the rear member having a heel edge and a toe edge, wherein the rear member is at least partially received within the rear cavity;
a resilient material positioned between the rear member and the face member; and
an engagement member rigidly engaging the face member and the rear member at a point between the heel edge and the toe edge of the rear member, wherein the engagement member has a rigidity greater than that of the resilient material and forms a sole area of rigid engagement between the face member and the rear member,wherein the resilient material is positioned between the engagement member and the heel edge of the rear member and between the engagement member and the toe edge of the rear member, andwherein the engagement member, a center of gravity of the face member, and a center of gravity of the rear member are all positioned in lateral alignment.

Abstract
Golf club heads include a face member with a face having a striking surface and a rear side opposite the striking surface, where a rear cavity is defined on the rear side of the face member, and a rear member is connected to the rear side of the face member, such that the rear member is at least partially received within the rear cavity. A resilient material is positioned between the rear member and the face member, and the head also includes an engagement member rigidly engaging the face member and the rear member at a point between the heel edge and the toe edge of the rear member. The engagement member has a rigidity greater than that of the resilient material and may form a sole area of rigid engagement between the face member and the rear member.

12. An iron-type golf club head 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 perimeter weighting member extending around at least a portion of a periphery of the face member, wherein a rear cavity is defined on the rear side of the face member, such that the perimeter weighting member defines at least a portion of a periphery of the rear cavity; a rear member connected to the rear side of the face member, the rear member having a heel edge and a toe edge, wherein the rear member is at least partially received within the rear cavity; a resilient material positioned between a front side of the rear member and the rear side of the face member; and an engagement member rigidly engaging the face member and the rear member at a point located within the rear cavity and between the heel edge and the toe edge of the rear member, wherein the engagement member has a rigidity greater than that of the resilient material and forms a sole area of rigid engagement between the face member and the rear member, wherein a gap is defined in the resilient material to permit the engagement member to rigidly engage the face member and the rear member, wherein the engagement member is positioned in lateral alignment with at least one of a center of gravity of the face member and a center of gravity of the rear member, and wherein the engagement member has a modulus that is at least 10×
greater than a modulus of the resilient material. - View Dependent Claims (13, 14, 15)
