Stringing arrangement and ball sports racket having an arrangement of this type

Abstract

A stringing arrangement for a ball sports racket having a frame which surrounds a string array and in which the strings of a racket string-fitting are supported and guided by string guides formed on the frame, the string guides being formed asymmetrically in such a way that a free length of the string respectively guided on the string guide is, perpendicular to the striking direction and to a string-fitting plane of the racket, greater on one side of the string-fitting plane than on the other side of the string-fitting plane so that a tension and/or elasticity criterion of the stringing arrangement is different for each of the two sides of the string-fitting plane.

What is claimed is: 
     
         1 . A stringing arrangement for a ball sports racket comprising:
 a string array;   a frame that substantially surrounds the string array; and   string guides formed on the frame, the string guides supporting and guiding strings of a racket string-fitting,   wherein the string guides are formed asymmetrically such that a free length of the string respectively guided on the string guide is substantially perpendicular to a striking direction and to a string-fitting plane of the racket and is greater on a first side of the string-fitting plane than on a second side of the string-fitting plane so that a tension and/or elasticity criterion of the stringing arrangement is different for each of the first and second sides of the string-fitting plane.   
     
     
         2 . The stringing arrangement according to  claim 1 , wherein the string guides are designed in the form of openings as string channels which pass through the frame from an inside to an outside so that the channels have an asymmetrical widening at their opening facing the string array. 
     
     
         3 . The stringing arrangement according to  claim 2 , wherein the opening facing the string array is widened in the shape of a funnel parallel to the striking direction. 
     
     
         4 . The stringing arrangement according to  claim 2 , wherein the opening facing the string array is widened in a slot-like manner parallel to the striking direction. 
     
     
         5 . The stringing arrangement according to  claim 2 , wherein the opening facing the string array is widened in steps parallel to the striking direction. 
     
     
         6 . The stringing arrangement according to  claim 2 , wherein the opening facing the string array is curved in a convex manner such that it is curved at a transition to the frame and fits tightly to the played string. 
     
     
         7 . The stringing arrangement according to  claim 1 , wherein the asymmetrical string guide is created by a frame profile which is thickened on one side of the string-fitting plane. 
     
     
         8 . The stringing arrangement according to  claim 1 , wherein the asymmetrical string guide is created by stiffening the strings on one side. 
     
     
         9 . The stringing arrangement according to  claim 1 , wherein the asymmetrical string guide is created by a plurality of sleeve-like inserts fitted into the frame, the inserts being designed in such a way that the strings can move more freely on one side of the string-fitting plane compared to the other side of the string-fitting plane. 
     
     
         10 . The stringing arrangement according to  claim 9 , wherein the plurality of inserts are contiguous, connected in one piece, and abuts a frame side. 
     
     
         11 . A handle for a ball sports racket having a stringing arrangement according to  claim 1 , wherein the handle is provided with a haptically detectable attachment indicating an orientation of the string-fitting plane. 
     
     
         12 . A frame for a ball sports racket having a stringing arrangement according to  claim 1 , wherein the frame indicates an orientation of the string-fitting plane by a different coloring of the two playing sides.
