Tennis racquet with longitudinal asymmetry - has strips with holes for strings fixed to edge of frame and strips on one side being wider or thicker

摘要

The racquet has a handle (2) which is aligned along the longitudinal axis of the head (7). This divides the head into two parts. Strips (8A, 8B) are fixed in the groove in the frame and have holes through which the strings are threaded. They form a protective cover for the frame. The strips on one side of the frame and wider or thicker than those on the other side, to make the head asymmetric. A short narrow strip (8A) only has holes and wide long strip (8B), extending over the top of the frame, has holes and forms a protective cover. USE - Racket for ball game, such as tennis, with longitudinal asymmetry to improve precision of shots.
