A golf club head having a nonmetallic crown bonded to a frame in close proximity to the face.

A golf club head includes a body having a face plate having a strike surface and an opposing interior surface, a rear end, and a sole connecting the faceplate with the rear end. The face plate, the rear end, and the sole partially define a cavity. An insert is positioned within the cavity, the insert presenting an insert surface facing the interior surface of the face plate and spaced therefrom.

Embodiments of golf clubs head sets with varying characteristics are disclosed herein. Other examples and related methods are also generally described herein.

A golf club head includes a golf club head body, a striking face, and an inner wall supporting the striking face. A ledge extends from a body into the interior of the golf club head body, and the inner wall is disposed within a gap between the striking face and the ledge. A rear surface of the inner wall is supported by a portion of the golf club head body, and a rear surface of the striking face is in contact with a portion of the inner wall. The inner wall may be inserted into the golf club head through an opening defined in the toe portion of the golf club head or the rear portion of the golf club head.

Disclosed herein are various embodiments of a golf club head having improved mass distribution characteristics. The golf club head includes a body and a face positioned at a forward portion of the body. The golf club head also includes one or more mass elements positioned at predetermined locations about the head. The mass elements assist in achieving a desired relationship between the moment of inertia about a center of gravity x-axis and the moment of inertia about a center of gravity z-axis.

Embodiments of golf clubs head sets with varying characteristics are disclosed herein. Other examples and related methods are also generally described herein.

A golf club head according to the disclosure is a cavity-back iron type golf club head that includes a face portion, a cavity portion provided behind the face portion, and a protrusion provided on a lower part of a rear face of the face portion. The protrusion includes a first recess extending from an upper surface of the protrusion toward a sole, a second recess positioned closer to a toe than the first recess is and extending from the upper surface of the protrusion toward the sole, and a thick portion provided between the first and second recesses in a toe-heel direction. The first and second recesses each has a substantially trapezoidal shape in a cross-sectional view taken along a plane that is parallel to a front face of the face portion and passes through a deepest part of each of the first and second recesses.

A golf club head includes a main body having a topline and an opposing sole. The main body includes a striking face extending between the topline and sole, and a rear face in opposed relation to the striking face. A sole body is proximate the rear face and extends at least partially along the sole. A peripheral flange extends at least partially about the rear face and is of a flange height, H.sub.F, relative to the rear face. A truss protrudes from the rear face and includes a at least a first truss arm which is of a first truss arm height, H.sub.T1, relative to the rear face, wherein the difference between H.sub.F and H.sub.T1 is less than about 0.25 mm.

A golf club head having a golf club head body and an inner wall structure. The club head body includes a back portion, a striking face, a sole, and a topline. The inner wall structure is at least partially in contact with a rear surface of the striking face. The inner wall structure also has a fixed end and an unfixed end. The golf club head is also configured such that the portion of the inner wall structure in contact with the rear surface of the striking face may slide against one another. The golf club head may also include a sole channel, and the fixed end of the inner wall structure may be attached to either a front edge or back edge of the sole channel.

A method for manufacturing a golf club head including a golf club head body, a striking face, and an inner wall supporting the striking face. A ledge extends from a body into the interior of the golf club head body, and the inner wall is disposed within a gap between the striking face and the ledge. A rear surface of the inner wall is supported by a portion of the golf club head body, and a rear surface of the striking face is in contact with a portion of the inner wall. The inner wall may be inserted into the golf club head through an opening defined in the toe portion of the golf club head or the rear portion of the golf club head.
