Abstract:
A ball racket having a racket head formed by a tension frame with stringing defining a stringing plane and a handle element connected to the tension frame by a core which is formed by a handle shaft and a handle, whereby the tension frame comprises two parts in at least part of the racket head, the two parts being a tension frame profile adjacent to the stringing and a supporting frame profile that is located in an outside in relation to the stringing, on which strings forming the stringing are held and which is pre-tensioned relative to the tension frame profile for the purpose of tensioning the strings, wherein the tension frame profile is a hollow profile closed on its total perimeter, the supporting profile has two wing like profile sections extending away from a middle line of the supporting profile and the stringing plane in opposite directions, the supporting profile has, along the middle line: a plurality of eyelets, or bare holes for the strings of the stringing; at least one damping or a tension element in a space formed between the supporting profile and the tension frame profile and acting between the profiles, each supporting profile sections forming a free end, and resting with the free tightly against an outer surface of the closed perimeter of the tension frame profile and thereby closing the space to the outside, wherein the at least one damping and/or tension element is a lumen filled with a liquid, gas or vapor.
