Abstract
A string tensioning system is provided for ball rackets, in particular for tennis rackets and squash rackets. The string tensioning system, formed by a string tensioning member (1), is insertable between the substantially parallel disposed strings (2 to 7) of a ball racket (19) such that these substantially parallel disposed strings are lifted up and down, respectively, relative to their original common plane and relative to each neighboring string of a parallel direction. Thereby the strings are retensioned and the original stringing hardness is recovered.
Claims1
A method for tensioning a stringed ball racket, comprising the steps of
- at a handle end of said head of said stringed ball racket, inserting an elongated string tensioning member between several substantially parallel disposed strings such that the elongated tensioning member is alternatingly disposed above a longitudinal side of a first one of the several substantially parallel disposed strings and below the longitudinal side of a second one of the several substantially parallel disposed strings, and wherein the elongated string tensioning member includes a middle borehole;
- inserting a pin of a tool into the borehole of the elongated string tensioning member;
- and
- flipping the elongated string tensioning member with the aid of said tool by an angle of 90.degree. around a center axis of the elongated string tensioning member.
