A golf club head includes a forward section and a body section. The forward section has a strike face, a frame that surrounds the strike face, and a flange extending from the frame. The body section is formed from a molded polymeric material, and includes a forward edge that defines a receiving portion adapted to receive the flange. When assembled, the flange extends within the receiving portion and the body section is adhered to opposing sides of the flange.

A golf club head with plate-like, heel and toe side internal stiffeners is disclosed herein. Each stiffener has a planar portion extending approximately parallel with a portion of the striking face, and is entirely disposed within an interior cavity of the golf club head. The heel side stiffener is connected to top, sole, and heel walls of the club head, with a toe-side edge unconnected to any other portion of the head, and the toe side stiffener is connected to the top, sole, and toe walls of the club head, with a heel-side edge unconnected to any other portion of the head. The toe and heel side edges may have large concavities that distribute mass away from the geometric face center and toward the heel and toe sides of the golf club head.

A golf club head includes a metallic front body coupled with a rear body to define a substantially hollow structure. The metallic front body includes a strike face and a surrounding frame that extends rearward from a perimeter of the strike face. The rear body includes a crown member and a sole member coupled to the crown member. The sole member comprises a structural layer formed from a filled thermoplastic material and a fiber reinforced composite resilient layer bonded to an external surface of the structural layer. The structural layer includes a plurality of apertures extending through a thickness of the structural layer, and the resilient layer extends across each of the plurality of apertures. The structural layer and the resilient layer each include a common thermoplastic resin component, and are directly bonded to each other without an intermediate adhesive.

A head for a ball striking device includes a bracing member connected to an upper sole surface located on the sole of the body opposite the bottom sole surface. The bracing member includes a first end connected to a first point on the upper sole surface, a second end connected to a second point on the upper sole surface spaced from the first point, and a bridge portion extending between the first and second ends. The bridge portion extends upward from the upper sole surface and is spaced from the upper sole surface. The bridge portion may be formed by one or more trusses, and may define a generally triangular shape in one embodiment. The first and second ends may be connected to the upper sole surface using a variety of techniques, e.g., welding or other integral joining technique, integral forming, adhesive or other bonding material, or other technique.

Golf club heads with ribs are described herein. A golf club head comprises a first rib protruding from an interior surface of the club head, and a second rib protruding from the interior surface of the club head. The first rib comprises a first axis and the second rib comprises a second axis; wherein the first and second rib axes intersect each other forward the front end of the club head body. The club head further comprises a first side rib protruding from the interior surface of the heel end, and a second side rib protruding from the interior surface of the toe end. The first side rib and the second side rib generally extend in a front end to rear end direction, and can be linear or curvilinear. The ribs provide structural support and sound control for the club head.

A golf club head with a channel sized to receive one or more adjustable weights and an external support structure that bridges, and thereby supports, the channel without unduly interfering with weight adjustment is disclosed herein. The support structure, which includes one or more stiffening members on the exterior of the golf club head, improves the sound quality of the golf club head, and is particularly useful to attenuate the lower frequency mode shapes associated with slider channel geometry in golf club heads.

A golf club head comprising a body, an elevated weight bar, and at least one stiffening member is disclosed herein. The elevated weight bar is disposed within a hollow cavity portion of the body and bridges at least a portion of a bottom section of the body, and the at least one stiffening member is also disposed within the hollow cavity portion, extending from a top line section to bottom section of the body and passing through the elevated weight bar without making contact with the elevated weight bar. The elevated weight bar, which is preferably composed of a higher density material than that of the body, may be formed separately from the rest of the body and then affixed to the body by welding or a mechanical fastener.

Golf club heads with ribs are described herein. Other embodiments and related methods are also disclosed herein.

A golf club head with a hollow therein comprises a face portion and a main body portion including a crown portion and a sole portion extending rearward from the face portion. The main body portion is provided with at least one slit penetrating through the main body portion. The slit has a width in the toe-heel direction and a length in the front-rear direction which is larger than the width. The surrounding area of the slit is at least partially provided with a thick portion.

A golf club head including a weight mount disposed on the sole, a weight member configured to reside in the weight mount, a compressible member residing between the weight member and the weight mount, wherein the weight member comprises a longitudinal axis about which the weight member is configured to rotate, the weight member comprising projections extending radially outwards from the longitudinal axis, wherein the weight mount comprises circumferential ramps, wherein rotation of the weight member about the longitudinal axis forces the projections along the circumferential ramps, wherein the weight member goes from an unlocked position to a locked position in less than one full turn of the weight member relative to the weight mount, wherein rotation of the weight member compresses the compressible member, wherein the circumferential ramps comprise detents, wherein the projections are configured to reside in the detents when the weight member is in the locked position.
