ABSTRACT:
A racket with a rugged frame adapted to be used in various games such as tennis, badminton, racket ball, squash tennis and etc. The racket includes a handle, a frame, and power reinforcing portions and flexible portions formed along a part of the frame or the entire frame in an alternating manner, each of the power reinforcing portions being constituted by a protruded frame portion having a relatively large side thickness while each of the flexible portions being constituted by a depressed frame portion having a relatively small side thickness, thereby capable of eliminating an insufficient power of the conventional classic type construction and an insufficient flexibility of the conventional wide body type construction, and attenuating a vibration generated when a ball strikes against the racket, thereby reducing an impact while providing a good ball striking feeling. In particular, the racket can control the flexibility and power appropriately depending on the feature of a user by adjusting the difference in thickness between the power reinforcing portion and the flexible portion both constituting the rugged frame construction and the number of protrusions and depressions respectively constituting the power reinforcing portions and the flexible portions.
