Abstract

Abstract A string system for rapidly stringing game racket frames ultilizing an improved string suspension system consisting of a plurality of openly accessible string support elements coacting with and spaced around the inner circumference of the racket frame and a prewoven net consisting of a plurality of interwoven longitudinal and latitudinal runs of strings, wherein the longitudinal and latitudinal strings, respectively, upon completing a run of predetermined length, each form a loop and begin another run of predetermined length in the opposite but predominantly parallel direction to and spaced apart from the preceeding run. This is continued with both the longitudinal and latitudinal strings, alternately interweaving the longitudinal and latitudinal strings until a woven net of predetermined size and shape is achieved with respect to the game racket frame to be strung. The loops of the prewoven net are attached to and supported by corresponding openly accessible string support elements of the string suspension system thereby combining the stringing and tensioning operations.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 189 words
A game racket and string system therefor comprising a racket frame having an unstrung open head portion, a handle portion and an intermediate throat portion, said head portion having string support means spaced about the inner periphery of said head portion for receiving said string system, said string system having substantially parallel runs of interwoven strings at right angles to each other, adjacent pairs of similarly oriented strings forming loops around the outer periphery of said string system with four terminal loops each formed by one run of string secured to itself, each of said loops and terminal loops respectively corresponding in spacing to the spacing of said string support means, the planar dimensions of the outer periphery of said string system in its normal, unstrung nontensioned condition being less by a predetermined amount than the planar dimension defined by the interior periphery of said string support means, whereby the respective loops of said string system are adapted to be directly stretched onto their respective string support means and result in a strung racket of a desired tension as determined by said predetermined lesser dimension of said string system.
Claim 2
Dependent Claim 189 words
A game racket and string system therefor comprising a racket frame having an unstrung open head portion, a handle portion and an intermediate throat portion, said head portion having string support means spaced about the inner periphery of said head portion for receiving said string system, said string system having substantially parallel runs of interwoven strings at right angles to each other, adjacent pairs of similarly oriented strings forming loops around the outer periphery of said string system with four terminal loops each formed by one run of string secured to itself, each of said loops and terminal loops respectively corresponding in spacing to the spacing of said string support means, the planar dimensions of the outer periphery of said string system in its normal, unstrung nontensioned condition being less by a predetermined amount than the planar dimension defined by the interior periphery of said string support means, whereby the respective loops of said string system are adapted to be directly stretched onto their respective string support means and result in a strung racket of a desired tension as determined by said predetermined lesser dimension of said string system.
