Sports rackets having all strings dampened for vibration

In a sports racket having a frame formed by a top portion, two opposed lateral portions connecting the top portion to a throat, a shank portion leading from the throat to a handle, and having a string network with longitudinal strings and cross strings defining a string network with its plane coinciding with the plane of the frame, the strings being arranged to enter and leave the frame, the improvement wherein

• the cross-section of the major portion of the frame is generally T-shaped, the frame including a central member having a plane of symmetry coinciding with the plane of the string network and defined by side walls, one on either side of said plane of symmetry, and a vertical member extending outwardly and symmetrically away from the plane of the string network, and
• including damping strips fastened on the surfaces of said side walls of said central member along major portions of the frame, said strips being in contact with the strings entering in and exiting from the frame at least when the strings are in vibration in the direction perpendicular to the plane of the string network, due to the impact of a ball against the racket.
