ABSTRACT:
A sports racket having a top portion, two lateral portions connecting the top portion to a throat, a shank portion, a handle, and a string network of longitudinal and cross strings defining a string network, is disclosed as having a frame structure with a T-shaped cross-section of a central member and a vertical member, the former having a plane of symmetry coinciding with the plane of the string network. The central member is arranged so that the strings wrap around the same as the strings enter and exit the frame. The improvement includes damping strips fastened to upper and lower surfaces of the central member positioned on either side of the plane of the string network to be engageable with the strings as they enter and leave the frame during vibration thereof.
