Stringing device for sports racket

Abstract

A stringing device for a sports racket includes a base and a cleat. The base has a pair of opposing side ends, an upper surface and a bottom surface. The base further has a guiding groove with an open end and a string engaging surface. The cleat extends downward from the bottom surface of the base and has a guiding channel with an inlet and an outlet. The inner diameter of the guiding channel is larger than the outer diameter of the racket string. The string engaging surface of the guiding groove has a suspending portion corresponding to the inlet of the guiding channel for guiding a racket string entering/exiting from the open end of the guiding groove to thread through the guiding channel from the inlet or outlet thereof without touching the inner wall of the guiding channel.

         8 . The device according to  claim 7 , wherein each of said suspending portions is a projecting area. 
     
     
         9 . The device according to  claim 8 , wherein each of said suspending portions has a curved bearing surface. 
     
     
         10 . The device according to  claim 8 , wherein the diameter of said inlet is smaller than that of said outlet. 
     
     
         11 . The device according to  claim 7 , wherein said cleat extends at least partially through a string hole of a sports racket. 
     
     
         12 . A sports racket, comprising a head frame defining an opening, a plurality of string holes formed in said head frame toward said opening and at least a string device of  claim 7 , said string device being disposed on said head frame in such a way that said cleat thereof is at least partially and tightly inserted into one of said string holes. 
     
     
         13 . A stringing device for sports racket, comprising:
 an elongated base having opposing longitudinal ends, a longitudinal upper surface and a longitudinal bottom surface opposed from said upper surface, each of said surfaces extending between said opposing longitudinal ends;   a pair of cleats respectively disposed at each of said opposing longitudinal ends of said base and extending downward from said bottom surface of said base, each of said cleats having a guiding channel through which a racket string threads, said guiding channel having an inlet near one of said opposing longitudinal ends of said base, an outlet opposed from said inlet, and an inner diameter being larger than the outer diameter of a racket string threading therethrough;   said base further having a guiding groove running longitudinally along said upper surface thereof, said guiding groove having opposing longitudinal open ends and a string engaging surface disposed between said open ends for engaging and receiving a string which is looped thereover; and   said string engaging surface of said guiding groove having a pair of suspending portions, each of said suspending portions disposed near each of said open ends and corresponding to said inlet of said guiding channel of each of said cleats for guiding a racket string to thread through said guiding channel without touching the inner wall thereof.
