Racket stringing

A racket having an improved stringing network, said racket comprising:

• a frame enclosing an annular opening and having a handle extending longitudinally from a bottom end thereof;
• a first plurality of generally aligned main string crossings traversing the frame opening in a generally longitudinal direction from the top of the frame to the bottom of the frame;
• a second plurality of generally aligned generally lateral string crossings traversing the frame opening from one side of the frame to the opposite side of the frame and weaving through the first plurality of string crossings;
• said first plurality of generally aligned main string crossings consisting of successively adjacent string crossings in which the three outermost string crossings on each side have relatively large spacing from each other and the remaining, central, string crossings have substantially smaller spacing from each other, the outermost string crossings on each side having relatively large spacing from the frame side to thereby have only relatively long main strings and decrease coupling of the stringing network to the frame;
• a predetermined plurality of the second plurality of lateral string crossings being relatively long plural strand string crossings traversing across the central region of the frame opening to stiffen the central region and to thereby greatly reinforce the widely spaced outer mains with relatively long plural strand string crossings.

• a first plurality of generally aligned string crossings traversing the frame opening from a first section of the frame to an opposite second section of the frame;
• a second plurality of generally aligned string crossings traversing the frame opening from a third section of the frame to an opposite fourth section of the frame, said second plurality of string crossings making large angles near 90.degree. with the first plurality of the string crossings and weaving through the first plurality of string crossings;
• said second plurality of string crossings including first, second and third successive adjacent string crossings, said first and third string crossings being generally aligned straight single strand string crossings having respectively opposite weave senses through the first plurality of string crossings, said second string crossing being a plural strand string crossing comprising a pair of adjacent strings 2a and 2b, respectively, having opposite weave sense to each other and entering and leaving the frame opening together through common frame apertures, string 2a being positioned between the first string crossing and string 2b, and string 2b being positioned between string 2a and the third string crossing.
