Abstract: A racket frame of extruded aluminum with a common cross-section along its entire length. The frame has free ends with frame portions adjacent to the free ends shaped parallel with each other to constitute a handle. The frame is shaped in a curved configuration remote from the handle with a central opening therewithin to form a head. The opening has a central axis. The frame is shaped with a transition zone between the head and the handle. The cross-section of the frame is of an exterior closed configuration with a major axis parallel with the central axis and a minor axis perpendicular to the major axis. The cross-section of the frame has two interior ribs spaced from each other to divide the cross-sectional configuration into three linear openings with the ribs being angled equally and oppositely with respect to each other.

Abstract: A tennis racket comprising a head formed as a closed loop at the upper end, a handle for being gripped by a player at the lower end and coupling beams therebetween, the head being formed with varied inertial cross-sectional configurations around its periphery with a nearly circular cross-sectional configuration at the upper edge of the head and the lower edge of the head and with an oval wide-beam cross-sectional configurations at the sides of the head between the 2 and 5 o'clock positions and the 7 and 10 o'clock positions for generating a stiffness that is about 70% of the other sections which have nearly circular cross-sectional configuration and strings in a plane secured in the head.
