  • Patent number: 4741531
    Abstract: A stringing system for a racket consisting of two elements, a prewoven net of individual strings and a two piece fixing device, acting as a string clamp in the string hole of a racket frame under the string's own tension. A first member of the fixing device is tubular in shape and is designed to extend through the interior of the racket frame hole. Its upper portion extends outward from the frame hole and has a slot which separates it into two half shells. A second member of the fixing device is placed over the frame hole and is located entirely exteriorly of the hole. The exterior surface of the second member is adapted to the profile of the racket frame. During stringing of the racket, the first member is placed inside the second member and into the frame hole. The string is passed through the hole in the first member, such that when the first member slides into the second member, its two half shells are pressed together around the string to hold the string in place when under tension.
