  • Publication number: 20140011615
    Abstract: A stringing means is made integrally with, or an independent device secured on, the throat of a badminton racket. The badminton racket includes a hoop-shaped head with a longitudinal axis, a shaft and a throat connecting the shaft to the head along the longitudinal axis thereof. The head of the racket defines a stringed hitting surface with a sweet zone. The stringing means comprises at least two guiding holes and a guiding channel. Each of the guiding holes is spaced apart in a predetermined distance and includes an opened outer end to be as a string inlet and an inner end connected with the guiding channel. When a badminton racket is equipped with such a stringing means, portions of the string chords for forming the sweet zone of the stringed hitting surface can thread through the means and extend in parallel with the longitudinal axis of the head.
