Abstract: A golf club head includes a club head body and a weight member that is secured to the body in a weight mount. The weight member is constructed to utilize lateral forces to couple to the head body to minimize the structure required to retain the weight member. The weight member includes a spring feature that is movably coupled to a weight body so that it is movable between a first configuration and a second configuration. In the second configuration a portion of the spring feature extends outward from a side wall of the weight body. The weight mount includes an undercut and the spring feature extends into the undercut and is partially flexed by the abutment of the spring feature and a perimeter wall of weight mount when the weight member is disposed in the weight mount.

A second rib may also be included in the golf club head and the symmetric portion of the striking face is defined by contact with the topline, the sole portion, the first rib, and the second rib. A flex support structure may also be incorporated into the golf club head. The flex support structures may have multiple profiles that contact the rear surface of the striking face at differing deflection depths.

Abstract: A golf club incorporating an interchangeable shaft system includes a shaft, a shaft sleeve, a club head. The shaft sleeve is coupled to an end of the shaft and is received in a hosel included in the club head. The shaft sleeve is removably coupled to the club head. Hosel and shaft sleeve alignment features provide discrete orientations between the shaft and club head.

Abstract: 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.

Abstract: The present invention is direct to a set of golf clubs comprising long irons, mid-irons and short irons. The invention contemplates the use of titanium or steel for the main body portion and significant tungsten weight members coupled to at least the toe via a mechanical fastener inserted through the face.

Abstract: A set of iron type golf club heads comprising a plurality of iron type golf club heads, the plurality of iron type golf club heads comprising a long iron, a mid iron, and a short iron; wherein each of the plurality of iron type golf club heads comprise a striking face, and wherein each of the plurality of iron type golf club heads comprise a plurality of grooves formed in the striking face extending generally from a heel side of the striking face towards a toe side of the striking face; wherein the plurality of grooves of each of the plurality of iron type golf club heads comprise an edge radius, wherein the edge radius of the plurality of grooves of the long iron is greater than the edge radius of the plurality of grooves of the short iron.

Abstract: The present invention is directed to a set of golf clubs comprising long irons, mid irons and short irons. The irons have a progressive horizontal CG location. Preferably, the long and mid irons have a face stabilizing bar and back panel and the CG is located between about 1 mm and 3 mm towards the hosel and the CG in the short irons is located between about 3 mm and 4 mm toward the hosel. Further the long and mid irons irons can have a plurality of apertures in the face stabilizing bar and/or the back wall.

Abstract: The present invention is direct to a set of golf clubs comprising long irons, mid-irons and short irons. The long irons have a first center of gravity positioned horizontally from the face center toward the hosel by a first distance. The mid-irons have a second center of gravity positioned horizontally from the face center toward the hosel by a second distance. The short irons have a third center of gravity positioned horizontally from the face center toward the hosel by a third distance that is greater than the first and second distances.

Abstract: A co-forged iron type golf club is disclosed. More specifically, the present invention discloses a co-forged iron type golf club with the body portion made out of a first material and at least one weight adjustment portion monolithically encased within the body portion of the co-forged iron type golf club head without the need for secondary attachment or machining operations. The present invention creates of an iron type golf club head from a pre-form billet that already contains two or more materials before the actual forging process resulting in a multi-material golf club head that doesn't require any post manufacturing operations such as machining, welding, swaging, gluing, and the like.

Abstract: A golf club that utilizes multiple materials to achieve improved performance is disclosed herein. More specifically, the present invention relates to a method of forming golf club that utilizes different materials to construct different portions of the iron type golf club head allowing weight to be removed from portions of the golf club head that doesn't require such weighting. The current invention utilizes a lightweight material to form a blade portion of the golf club head while utilizing a standard steel material to form the hosel portion of the golf club head to allow the malleability characteristics of a golf club head to be maintained. The weight saved from the lightweight material used to create the blade portion can then be used to create a sole insert that is made out of a dense and heavy material to improve the CG and MOI characteristics of the golf club head to dramatically improve the performance of the golf club head.
