ABSTRACT:
This invention provides a racket that allows for the adjustability of balance within the structure of the racket. The racket's adjustment mechanism and its function are easy to use and optimize any player's game. The adjustment mechanism resides in the handle in a manner that does not substantially (or in any way) alter the aerodynamic profile of the racket or affect its usability by providing unwanted external structures. Rather a movable mass/weight is contained within a hollow space of the handle and can be moved upwardly and downwardly along the handle using a guide mechanism and fixing or locking structure that can be illustratively activated by rotating a knob at the lower end of the racket handle (or by another low-profile external trigger). This can comprise a shaft with a thread or key that engages a corresponding thread or key slot on the mass/weight. The knob can include an indexing mechanism that facilitates rotatable restraint and/or alignment of the knob when not in use.
