A racket for a racket sport has a frame having a handle and an annular frame head carried on the handle and formed with throughgoing stringing holes each having an outer end and an inner end. Liners define rigid edges around the outer edges of at least selected ones of the holes and strings pass through the holes in the frame, those strings passing through the selected ones of the holes being bent around and in contact with the rigid edges thereof. Respective pliable washers received in the selected ones of the holes offset from the respective ridged edges thereof each have an inner periphery elastically hugging the string traversing the respective hole for damping vibration in the head and an outer periphery fixed relative to the frame head.

Tennis racket with vibration-damping stringing

A strung racket having a racket head in the form of a frame strung with stringing including longitudinal strings passing between a crown and a bottom of the frame and transverse strings extending transversely to the longitudinal strings between sides of the frame, the strings passing through holes in the frame. A device for damping vibration of the stringing generated by impact of the stringing with a ball, is provided and includes at least one pliable membrance fixedly received in at least one of the holes of the bottom of the frame and having an orifice tranversed by the respective string, the edge of the pliable membrane hugging the string traversing the frame hole.

A tennis racket has an elongated handle defining a longitudinal main axis and having an outer end and an annular frame fixed to the outer handle end and bisected by the axis. The frame has an arcuate crown concave toward the handle and an arcuate throat concave toward the handle and of substantially the same transverse size and curvature as the crown. The crown and throat are formed with respective longitudinally aligned sets of longitudinally throughgoing and transversely spaced holes. In addition the frame has a pair of sides substantially symmetrically flanking the axis and longitudinally bridging the crown and throat. These sides are formed with respective transversely aligned sets of transversely throughgoing and longitudinally spaced holes. The crown and sides together define an oval outer periphery. The side holes open outward at their outer ends into respective outwardly open grooves in the sides of the frame. Main strings extending longitudinally between respective holes of the crown and throat substantially parallel to the axis and cross strings extending transversely generally perpendicular to the axis between respective holes of the sides together define a central spot of predetermined longitudinal length and transverse width. The depth of the groove and of the inner side edge is such that the transverse lengths of the cross strings traversing the spot are all substantially identical between the respective outer and inner hole ends.
