1. A golf club head comprising:
- a club head body comprising a front portion, a rear portion, a ball-striking face, a heel, a toe, a crown, and a sole;
a recess extending along a length of the sole, the recess having a first end defining a first weight mounting portion and an opposing second end defining a second weight mounting portion;
an adjustable weighted member coupled to the recess, the weighted member having at least a first outermost end and an out-of-plane axis;
a fastener coupling the weighted member to the recess and enabling the weighted member to rotate about a longitudinal axis of the fastener corresponding to the out-of-plane axis of the weighted member, thereby allowing the weighted member to transition between a first position and a second position relative to the recess while remaining coupled to the recess;
wherein, when in the first position, at least the first outermost end of the weighted member is positioned within the first weight mounting portion and is oriented in a first direction with respect to the recess, and, when in the second position, at least the first outermost end of the weighted member is positioned within the second weight mounting portion and is oriented in a second direction with respect to the recess and opposite the first direction.

Abstract
The invention generally relates to golf clubs with adjustable mass properties. In certain aspects, the invention provides methods and mechanisms for adjusting a club head center of gravity and/or moment of inertia by way of an adjustable weight assembly positionable along the sole of the club head body. When in a first position, the weight assembly provides a lower center of gravity so as to increase launch angle and reduce spin rate, resulting in greater overall distance of ball flight. When in a second position, the weight assembly provides a greater mass moment of inertia, which effectively enlarges the sweet spot and produces a more forgiving club for off-center hits.

16. A method for adjusting the mass properties of a golf club head, the method comprising:
-
providing a golf club head comprising; a club head body comprising a front portion, a rear portion, a ball-striking face, a heel, a toe, a crown, and a sole; a recess extending along a length of the sole, the recess having a first end defining a first weight mounting portion and an opposing second end defining a second weight mounting portion; an adjustable weighted member coupled to the recess, the weighted member having at least a first outermost end and an out-of-plane axis; and a fastener coupling the weighted member to the recess and enabling the weighted member to rotate about a longitudinal axis of the fastener corresponding to the out-of-plane axis of the weighted member, thereby allowing the weighted member to transition between a first position and a second position relative to the recess while remaining coupled to the recess; and adjusting at least one of center of gravity and mass moment of inertia of the golf club head by moving the weighted member between the first position and the second position; wherein, when in the first position, at least the first outermost end of the weighted member is positioned within the first weight mounting portion and is oriented in a first direction with respect to the recess, and, when in the second position, at least the first outermost end of the weighted member is positioned within the second weight mounting portion and is oriented in a second direction with respect to the recess and opposite the first direction. - View Dependent Claims (17, 18, 19, 20)
