[origin: US4949968A] PCT No. PCT/DE87/00418 Sec. 371 Date May 17, 1988 Sec. 102(e) Date May 17, 1988 PCT Filed Sep. 16, 1987 PCT Pub. No. WO88/01889 PCT Pub. Date Mar. 24, 1988.A racket for ball games, in particular tennis, comprises a stringing system in the form of individual strings. The individual strings are each held in the racket frame by means of rivet sleeves, with the rivet heads bearing against the outer edges of the holes in the racket frame. In the event of a string breaking, there is no reaction on the adjoining strings, and only the broken string has to be changed. The individual strings which are provided for the first stringing or for replacement stringing have a fixedly disposed rivet sleeve at one end. In addition there is a loose rivet sleeve which is intended for being pushed on and connected after the string has been inserted into oppositely disposed holes. In addition described is a stringing device of simple design, by means of which individual strings can be easily replaced even by technically unskilled persons.
