发明名称 String protector for a racket frame
摘要 In construction of an attachment-type string protector for racket frames including a base strap and a number of sleeves aligned on the base strap, the base strap is made of a relatively rigid synthetic resin, and a number of tubular vibration absorbers made of a soft synthetic material are inserted into respective sleeves almost over the entire length of the latter in full surface contact with strings. Full surface contact of the vibration absorbers with the strings over an increased length assures high degree of impact damping at shooting balls.
