The present invention relates to an iron-type golf club head having a lightweight hosel and a high, toe-ward located center of gravity. The golf club head preferably includes a hollow body with a hosel and an interior mold line that extends into the hosel and is separated from a shaft bore by a solid barrier that does not include any through-holes. An upper portion of the body may include a pocket to hold a high-density weight, and the hosel wall may include multiple through-bores to further lighten the hosel. The golf club head may also include one or more internal ribs extending from the hollow interior of the body into the interior of the hosel.

Iron-type golf club head with lightweight hosel

The present invention relates to a hosel for connecting a shaft to a club head. In one aspect of the invention, the hosel comprises a body having an undercut, wherein the undercut has a maximum cross section which tapers to a minimum cross section and increases to the maximum cross section immediately adjacent the club head. The hosel further comprises a flange section below the hosel and hosel bore above the undercut, the hosel bore section having a length of at least one inch. In another aspect of the invention, the hosel tapers in diameter from a maximum to a minimum width, and has a maximized interior mold line (IML) to improve bendability and weight savings.

Hosel construction

A golf club () having a club head () with a face component (), an aft body (), and a sound modifying sole and crown design is disclosed herein. The face component, which may be composed of a metal material, () has a striking area portion () and a return portion (). The aft-body (), which may be composed of a non-metal material such as composite or thermoplastic material, is composed of a crown portion () and a sole portion (). The sound modifying design, which may include deep pockets or pillars extending from the sole portion () to the crown portion (), alters the sound of the golf club head () when it impacts a golf ball.

A golf club iron having a head center of gravity that is low and forward enough to provide a better swing, good striking and swinging feel, and improved ball flight is disclosed. The iron has a recess in a leading edge region and a high density insert disposed within the recess to achieve the desired center of gravity location.

A variable length shaft assembly comprising at least one upper shaft portion, a lower shaft portion and a threaded fastener, wherein the threaded fastener removably connects the upper shaft portion to the lower shaft portion, is disclosed herein. The variable length shaft assembly may further comprise at least two upper shaft portions having different lengths so a golfer can adjust the total length of the shaft by removing one upper shaft portion and replacing it with another upper shaft portion having a different length. Methods of adjusting the length of a golf club shaft without damaging any portion of the shaft and variable length shaft kits are also disclosed herein.

A golf club () having a club head () with a face component (), an aft body (), and a sound modifying sole and crown design is disclosed herein. The face component, which may be composed of a metal material, () has a striking area portion () and a return portion (). The aft-body (), which may be composed of a non-metal material such as composite or thermoplastic material, is composed of a crown portion () and a sole portion (). The sound modifying design, which may include deep pockets or pillars extending from the sole portion () to the crown portion (), alters the sound of the golf dub head () when it impacts a golf ball.

A golf club head () with a face component (), an aft body (), and an aerodynamic hosel () is disclosed herein. The hosel () has one or more joints () around which pieces or segments of the hosel () may be rotated or pivoted to modify the way in which a shaft is oriented with respect to the club head () when the hosel () is rigidly affixed to the club head (). The present invention may be used to modify the loft, lie, and/or face angle parameters of the golf club head.

Golf club head with improved aerodynamic characteristics

A driver type golf club head comprising a body having a face, a crown and a sole, wherein the highest point of the crown surface is located within a crown apex zone, and the club head has a depth, the depth being at least twice the length as a height of the club head, wherein the depth is at least 4.600 inches.

A golf club comprising an adjustable fitting member semi-permanently attached rearwardly on a sole is disclosed herein. The fitting member can be rotated to adjust the measured and perceived face angle of the golf club head at address without changing the relative relationship of the club with respect to the shaft, which would alter the lie and loft of the golf club head.
