TENNIS RACKET Russian patent published in 2011 - IPC A63B49/00 

FIELD: medicine, sport.

SUBSTANCE: invention relates to devices for playing tennis. Tennis racket differs by construction of net, whose string surface is made with cells in form of equilateral triangles, in whose apexes three strings interlace. Technical result of the invention is achieved by the following: successive transition of strings from point of interlacement in three to adjacent point is achieved with change of string position, and position of strings in two intersections, located over a single, is similar, either extreme, or middle. Claimed are two versions of net, ensuring maximal interlacing of three rows of strings with each other.

EFFECT: constructive peculiarity creates symmetry of string bend in net profile, therefore shape of cells after string tension remains undistorted in plan, that is, equilateral, and net ensures the most precise ball parryingl.
