Abstract
A racket includes a frame portion and a string which is threaded through the frame portion to be interlaced so as to form a first set of parallel string paths, a second set of parallel string paths, and a third set of parallel string paths. The string is threaded through the frame portion via the first, second and third sets of parallel string paths so that the string forms an approximately planar racket face. The first, second and third sets of parallel string paths intersect each other by an angle of approximately 120 degrees.
Claims5
A racket comprising:
- a frame portion;
- and
- a string which is threaded through said frame portion to be interlaced so as to form a first set of parallel string paths, a second set of parallel string paths, and a third set of parallel string paths;
- wherein said string is threaded through said frame portion via said first, second and third sets of parallel string paths so that said string forms an approximately planar racket face;
- and
- wherein said first, second and third sets of parallel string paths intersect each other by an angle of approximately 120 degrees.
A racket having a frame portion through which a string is threaded to form an approximately planar racket face;
- wherein said string is threaded through said frame portion to be interlaced triaxially in a hexagonal shape.
