An adjustable hosel assembly allows for adjustment of shaft angle and the distance between the shaft and the club head. The adjustable hosel assembly comprises a hosel portion, a cam piece, a bolt, and a golf club head having a convex or concave surface, wherein the hosel portion can move along the surface of the cam piece, and the cam piece can move along the surface of the club head, to adjust the orientation of a shaft placed within the hosel with respect to the club head, and wherein the bolt secures the cam piece and the hosel to the golf club head.

Adjustable golf club hosel assembly

A golf club head having a body, a hosel, and a bolt that connects the hosel to the body such that the hosel can rotate around the bolt is disclosed herein. In one embodiment, a worm gear engages gear teeth located at an interface of the hosel and the body, and turning the worm gear causes the hosel to rotate around the bolt. In another embodiment, a circular wedge is disposed between the hosel and the body, and rotating the circular wedge around the bolt changes the orientation of the hosel with respect to the body.

Golf club head with articulated hosel

A golf club head composed of a face component and an aft body composed of a long fiber material. The aft body is composed of a compression molded material. The compression molded aft-body is composed of two pieces which are bonded to a metal face component.

Golf club head with a compression-molded, thin-walled aft-body

A multiple-material golf club and a method for forming said golf club is disclosed herein. The multiple-material golf club preferably is a driver that has a metal face cup and a thin-walled, compression molded, composite aft body with precise IML and OML geometry. The molding composite used to form the compression molded aft body preferably comprises a plurality of randomly oriented carbon fiber bundles and a thermoset matrix material.

The present invention relates to a method for manufacturing a golf club head. The method comprises using a bladder with an open face and a flange clamped over the open face during pressurization and molding. In a preferred embodiment, the bladder is composed of a material with a higher rigidity than latex.

Method for manufacturing a golf club head

The present invention relates to a fairway wood type golf club head having a striking plate, a crown and a sole. The sole comprises a flat high strength region and dual regions with a low-friction, high release coating.

Reduced turf drag golf club head

A method for forming a golf club head having a volume of approximately 460 cubic centimeters, the method comprising the steps of casting a face component, attaching a bonding flange, stamping a metal sheet of titanium alloy to form a sole component, welding the sole component to the face component to create a golf club head subassembly having a weld line of approximately six inches and polishing the weld line.

Multiple material golf club head and a method for forming a golf club head

A method for creating a face of a golf club head with a preferred surface texture is disclosed herein. The method includes etching a non-scoreline portion of a face using a photosensitive coating that is activated with light to etch the face. The scorelines are protected from the etching process to maintain the well-defined geometries of the face.

Method and golf club

A club shaft that can be installed in a club head permanently or can be installed in clubs with interchangeable shaft features is disclosed herein. The invention is a measurement device that enables the capturing of the speed and motion of the swing. The invention uses two antennas, one transmitting and one receiving. The power of the radar wave is low. The wavelength will be on the order of a millimeter.

Device to measure the motion of a golf club through measurement of the shaft using wave radar

A golf club including a club head and an interchangeable shaft is disclosed herein. A connection assembly () comprises a sleeve insert (), a hosel sleeve (), a hosel tube (), a ring mechanism () and a guide ring ().

Connection assembly for a golf club

An iron-type golf club head having a coated stepped sole is disclosed herein. The coated stepped sole is stepped such that the sole surface furthest from the face is raised away from the turf to minimize the turf contact through a golfer's swing particularly for the longer, less lofted irons. The surface friction is reduced by applying a thin dense chromium coating thorough electroplating to the stepped sole.

Iron-type golf club head with chamfered leading edge

A club shaft that can be installed in a club head permanently or can be installed in clubs with interchangeable shaft features is disclosed herein. The invention is a measurement system that enables the capturing of the speed and motion of the golfer's swing. The invention uses magnetic material positioned on a face of a golf club head and an array of magnetic sensors.

Device to measure the motion of a golf club

A club shaft that can be installed in a club head permanently or can be installed in clubs with interchangeable shaft features is disclosed herein. The invention is a measurement system that enables the capturing of the speed and motion of the golfer's swing. The invention uses infrared reflectors positioned on a golf club and an array of infrared sensors.

The present invention discloses an iron-type golf club head in which the sole portion has a main surface and a stepped surface. Further, the sole portion comprises a chromium coating. The invention creates a unique combination of head shape and surface friction coefficients that minimize the bad effects of turf impact.
