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.
Claims
exact text as granted — not AI-modified1 . A ball sport or ball game racquet, in particular tennis racquet, 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 . A 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 . A 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 . A 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 . A ball sport racquet according to claim 1 , wherein a connection between the bearing element and the at least one string section extending away from said bearing element is offset radially from the pivot axis of the bearing element.
6 . A ball sport racquet according to claim 1 , wherein a pivot axis of the at least one bearing element is in the plane of the racquet stringing.
7 . A 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 . A 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 comprising a gliding and/or non-wearing material.
9 . A ball sport racquet according to claim 1 , wherein the racquet frame is a closed hollow frame.
10 . A 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, or with a coating made of PTFE.
11 . A ball sport racquet according to claim 1 , wherein the at least one bearing element is made of plastic, selected from a polyamide or POM.
12 . A ball sport racquet claim 1 , wherein at least two opposing bearing elements are provided on the racquet head frame in an axis direction that is perpendicular to the longitudinal axis (L) of the ball sport racquet.
13 . A ball sport racquet according to claim 12 , wherein 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 (L).
14 . A ball sport racquet according to claim 1 , wherein at least two bearing elements are provided on the racquet head frame on each side of the longitudinal racquet axis (L).
15 . A ball sport racquet according to claim 1 , wherein at least two string sections extend away from the at least one bearing element.Cited by (0)
