ABSTRACT:
A tennis racket having a frame with the cross section thereof constituted by a plurality of different shapes, including at least triangles and ellipses. The frame is constituted by three sections, of which the first is connected to the shaft of the racket via a base section and has an elliptical cross section so as to provide a more rigid percussion region and thus better control over tennis balls, the second is next to the tip of the frame and has a triangular cross section which is capable of supporting greater top and lateral forces resulting from contact with external objects, and the third is disposed between the first and second and has an intermediate shape that changes gradually from the ellipse of the elliptical section to the triangle of the triangular section so as to provide a connection and continuity between the two.
