Abstract
The present invention relates to an improved racket for ball games, in particular a tennis racket, squash racket, badminton racket, racquet ball racket or paddle tennis racket, comprising a frame consisting of a racket head and a handle portion connected thereto and being formed of a frame profile, wherein the racket head defines a stringing plane. The frame profile comprises at least one opening extending through the frame profile essentially perpendicular with respect to the stringing plane of the racket. Preferably, at least two openings of this kind are provided essentially symmetrical with respect to the longitudinal axis of the racket at about two o'clock to four o'clock and/or eight o'clock to ten o'clock on the racket head. Particularly preferably, the openings are at about three o'clock and/or nine o'clock. The racket of the present invention thus exhibits particularly advantageous ball control characteristics.
