Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a Continuation (CON) of U.S. patent application Ser. No. 17/863,328, filed Jul. 12, 2022, the disclosure of which is incorporated by reference in its entirety. FIELD OF THE INVENTION The Present Invention Relates Generally to a Golf Club Head, and More Specifically, to a Golf Club Head Having an Adjustable Weight Assembly BACKGROUND OF THE INVENTION It is no surprise that over time golf clubs have evolved and improved. However, golf club improvements are limited by the rules of golf. Golf club bodies are subjected to volumetric limitations and golf club faces are subjected to “speed limits” based on characteristic time (CT) and coefficient of restitution (COR). Golf clubs are even subjected to limitations on “forgiveness” in terms of various moments of inertias (MOIs) measured about the center of gravity (CG) of the golf club head. While the limitations on golf club seem substantial, there are still areas that are ripe for the picking. One such area is CG adjustability. By shaving mass from various areas of a golf club head, mass may be discretionarily concentrated in positions that afford the greatest performance benefits. Adjusting the CG location within a golf club head can result in the modification of all sorts of different aspects of the golf club. For example, adjusting the location and amount of discretionary weight within the golf club head can have a marked impact on launch angle, MOI, ball speed, spin, swing weight and the like. Therefore, what is needed is an adjustable weight assembly that allows for discretionary mass to be adjusted in a simple and secure manner.
