In a ball sport racquet, for example, a tennis racquet, made up of a main or racquet head frame, a throat with a throat bridge and side bridges diverging to the throat bridge and extending into a shaft, and strings fastened on the main frame and on the throat bridge, the throat bridge can move restrictedly relative to the main frame at least in one axis direction perpendicular to the plane of the strings and/or can rotate on the racquet frame on an axis extending in the direction of a longitudinal axis of the racquet.

Ball sport racquet especially tennis racquet

A ball game racket, especially a tennis racket, has a racket head formed by a tension frame with stringing, and a handle unit formed by a handle shaft or a racket neck joining the tension frame for example via a heart piece. Between a frame profile and the support profile a hose or cushion-type element is filled with an attenuating or damping liquid.
