Stringing means for a badminton racket

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.

         3 . The stringing means of  claim 2 , wherein said guiding channel has a curved bearing surface with opposing longitudinal ends. 
     
     
         4 . The stringing means of  claim 3 , wherein said guiding channel includes a pair of suspending portions, each of said suspending portions is disposed respectively on each of said longitudinal ends of said curved bearing surface. 
     
     
         5 . The stringing means of  claim 4 , wherein each of said suspending portions is a projecting area facing to each of said guiding holes. 
     
     
         6 . A badminton racket comprising a hoop-shaped head with a longitudinal axis, a shaft and a throat connecting the shaft to the head along the longitudinal axis thereof, said head having an inner surface, an outer surfaces and a plurality of string holes disposed between said inner and outer surfaces to be threaded through by a tensioned string to form a stringed hitting surface with a sweet zone; said racket further comprising a stringing means disposed on the throat thereof and constructed in such a way that portions of string chords of the sweet zone of the stringed hitting surface can thread therethrough and extend in parallel with the longitudinal axis of the head. 
     
     
         7 . The badminton racket of  claim 6 , wherein said stringing means is integrally formed with the throat and comprises at least two guiding holes spaced apart in a predetermined distance and a guiding channel, each of said guiding holes includes an opened outer end to be as a string inlet and an inner end connected with said guiding channel. 
     
     
         8 . The badminton racket of  claim 7 , wherein said guiding channel has a curved bearing surface with opposing longitudinal ends. 
     
     
         9 . The badminton racket of  claim 8 , wherein said guiding channel further includes a pair of suspending portions, each of said suspending portions is disposed respectively on each of said longitudinal ends of said curved bearing surface. 
     
     
         10 . The badminton racket of  claim 9 , wherein each of said suspending portions is a projecting area facing to each of said guiding holes. 
     
     
         11 . The badminton racket of  claim 7 , wherein the string holes includes two upper string holes disposed on the upper portion of the head, each of said upper string holes respectively corresponds to one of said guiding holes such that each of said upper string holes and each of said guiding holes to which said upper string hole corresponds are in a common axis. 
     
     
         12 . The stringing means of  claim 1 , wherein said stringing means comprises a block body secured on the throat of the badminton racket. 
     
     
         13 . The stringing means of  claim 12 , further comprising at least two guiding holes and a guiding channel, each of said guiding holes being disposed on said body and spaced apart in a predetermined distance, each of said guiding holes including an opened outer end to be as a string inlet and an inner end, said guiding channel being disposed on said body and connected with said inner end of each of said guiding holes. 
     
     
         14 . The stringing means of  claim 13 , wherein said guiding channel has a curved bearing surface with opposing longitudinal ends. 
     
     
         15 . The stringing means of  claim 14 , wherein said guiding channel further includes a pair of suspending portions, each of said suspending portions is disposed respectively on each of said longitudinal ends of said curved bearing surface. 
     
     
         16 . The stringing means of  claim 14 , wherein each of said suspending portions is a projecting area facing to each of said guiding holes. 
     
     
         17 . The stringing means of  claim 12 , wherein said body includes through holes to be tightly secured on the throat of the badminton racket by screws or the like.
