Golf club weight attachment mechanisms and related methods

摘要

A golf club head including a head body selected from a group of golf club heads consisting of a fairway-wood type head, a driver-type head, and a hybrid-type head, the head body bounding an interior cavity and comprising a body opening. A shell portion is configured to couple to the body opening. The shell portion includes a first shell side, a second shell side opposite the first shell side, and a capsule defined between the first and second shell sides. The shell portion also includes first and second shell sheet capsule sections that define the capsule and contain a weight member. A density of the weight member is greater than a density of the shell portion.

first and second shell sides opposite each other; anda capsule defined between the first and second shell sides and containing the weight member;a density of the weight member is greater than a density of the shell portion and a density of the head body;the first shell side, the capsule, and the weight member, are internal to the interior cavity;when encapsulated, the weight member is configured to remain substantially within the capsule of the shell portion;the shell portion comprises at least a portion of a sole of the golf club head, and is located closer to a front portion of the head body than a rear portion of the head body;the weight member comprises:
a weight mass;a weight thickness of:
less than approximately 6.4 mm if the golf club head comprises the fairway-wood-type head;less than approximately 5.5 mm if the golf club head comprises the driver-type head; orless than approximately 8.5 mm if the golf club head comprises the hybrid-type head;a weight volume of:
less than approximately 15 cc if the golf club head comprises the fairway-wood-type head;less than approximately 12 cc if the golf club head comprises the driver-type head; orless than approximately 20 cc if the golf club head comprises the hybrid-type head;a specific gravity of approximately 18 to 20; andat least one of:
a tungsten material;a nickel material;a cadmium material;a copper material; ora metal-infused plastic material;the shell portion comprises at least one of:
a steel material; ora titanium material;the weight member adjusts a center of gravity of the golf club head:
at least 0.38 mm towards the sole if the golf club head comprises the fairway-wood-type head;at least 0.25 mm towards the sole if the golf club head comprises the driver-type head; orat least 0.4 mm towards the sole if the golf club head comprises the hybrid-type head;the weight mass is:
at least approximately 9.5% of a mass of the golf club head if the golf club head comprises the fairway-wood-type head;at least approximately 3% of the mass of the golf club head if the golf club head comprises the driver-type head; orat least approximately 12% of the mass of the golf club head if the golf club head comprises the hybrid-type head;andthe weight volume is:
at most approximately 14% of a volume of the golf club head if the golf club head comprises the fairway-wood-type head;at most approximately 5% of the volume of the golf club head if the golf club head comprises the driver-type head; orat most approximately 30% of the volume of the golf club head if the golf club head comprises the hybrid-type head.
