ABSTRACT:
A frame is disclosed for use as a sports racket, the frame being closed to surround and support a string network comprising longitudinal and cross strings to define a ball hitting region. The midplane of the frame or that plane which extends through the center thereof whereby one closed side of the frame is symmetrical with the other closed side is in coincidence with the plane of the string network as is typical with sports rackets. The frame structure is formed by an outer wall and an inner wall spaced inwardly from the outer wall toward the string network, with both walls being perpendicular to the midplane of the frame. A multiplicity of plate-like panels arranged perpendicular to the midplane of the frame are connected to and between the walls to provide a unified frame structure. The panels are spaced from each other and the walls to define open spaces which extend through the frame from one side thereof to the other and without obstruction therein. The width of the walls may be of different dimensions and the angular orientation of the panels relative to the walls may assume different values.
