Ball play racket, especially tennis racket

Abstract

The invention relates to a ball sport racquet, in particular tennis racquet, with a racquet frame, which is manufactured as one piece with a racquet head frame supporting the racquet strings and with a racquet neck or racquet shaft, wherein the racquet stringing is formed by crisscrossing strings or string sections forming a string bed and held on the racquet frame head.

1 . A ball sport or ball game racquet with one racquet frame, which is manufactured as one piece with a racquet head frame supporting the racquet stringing and with a racquet neck or racquet shaft, wherein the racquet stringing is formed by crisscrossing strings or string sections forming a string bed and held on the racquet frame head, wherein at least part of the strings or string sections forming the racquet stringing are held on at least one bearing element, which is provided so that it can pivot on the racquet frame head on an axis tangential to the course of the racquet frame head.  
   
   
       2 . The ball sport racquet according to  claim 1 , wherein the at least one bearing element encloses the racquet head frame on its outer surface with one eyelet-shaped section.  
   
   
       3 . The ball sport racquet according to  claim 1 , wherein the racquet head frame in the area of the at least one bearing element features a cylindrically curved outer geometry on the pivot axis of the respective bearing element at least on its outer side facing away from the racquet stringing on sub-sections connecting to said outer side or transition sections to the inner side of the racquet head frame facing the racquet stringing.  
   
   
       4 . The ball sport racquet according to  claim 3 , wherein the at least one bearing element forms a bearing surface that is adapted to the outer geometry of the racquet head frame.  
   
   
       5 . The ball sport racquet according to  claim 1 , wherein the connection between the bearing element and the at least one string section extending away from said bearing element is offset radially from a pivot axis of the bearing element.  
   
   
       6 . The ball sport racquet according to  claim 5 , wherein the pivot axis of the at least one bearing element is in the plane of the racquet stringing.  
   
   
       7 . The ball sport racquet according to  claim 1 , wherein the at least one bearing element is manufactured with two sections, namely of one outer section and one inner section, and that both elements form at least one opening enclosing the racquet head frame when assembled.  
   
   
       8 . The ball sport racquet according to  claim 1 , wherein the racquet head frame, at least in the area of the at least one bearing element, features an outer surface consisting of a gliding and/or non-wearing material.  
   
   
       9 . The ball sport racquet  claim 1 , wherein the racquet frame is a closed hollow frame.  
   
   
       10 . The ball sport racquet according to  claim 1 , wherein the racquet head frame, at least in the area of the at least one bearing element, is provided with a gliding and/or non-wearing coating, a coating made of polytetrafluoroethylene.  
   
   
       11 . The ball sport racquet according to  claim 1 , wherein the at least one bearing element is made of plastic, polyamide, or POM.  
   
   
       12 . The ball sport racquet according to  claim 1 , further comprising at least two opposing bearing elements, which are provided on the racquet head frame in an axis direction that is perpendicular to the longitudinal axis of the ball sport racquet.  
   
   
       13 . The ball sport racquet according to  claim 12 , wherein the at least two pairs of opposing bearing elements are provided on the racquet head frame in an axis direction that is perpendicular to the longitudinal axis.  
   
   
       14 . The ball sport racquet according to  claim 12 , wherein the at least two bearing elements are provided on the racquet head frame on each side of the longitudinal racquet axis.  
   
   
       15 . The ball sport racquet according to  claim 1 , wherein at least two string sections extend away from the at least one bearing element.
