Title:
RACKET HAVING VERY LARGE STRING HOLES
Document Type and Number:
WIPO Patent Application WO/1994/026361
Kind Code:
A1
Abstract:
A racket wherein string holes are made large enough for a finger to pass therethrough in order to obviate a necessity of using grommets while increasing the strength of a frame thereof by making the side surface of the holes a continuous surface, easily setting strings, and increase the ball striking performance by expanding a range in which strings can move in the vicinity of the frame. In the configuration of the present invention, adjacent string holes in a conventional racket are integrated into a large string hole and string holes are not conventional opposed ones but are those which alternately confront each other by offsetting string holes at opposed positions by one string mesh size. Consequently, the number of string holes is reduced to about a half of that of the conventional racket. In addition, the holes are constituted by a continuous surface by a frame constituent member.
