Abstract

The stringing system for a tennis racquet involves the strings resting against the outer wall of the hollow frame. The outlet holes (1) for the strings (2) on the inside of the frame (3) are large enough for the strings not to touch the inside of the frame, even when force is exerted. The small holes (4) contain bushes (5) through which the strings pass. The bushes may be flexible to allow a gentle curve on the strings, which pass to the outside through one hole and in through the adjacent hole in the frame. USE/ADVANTAGE - The tennis racquet has a freely oscillating ball impact surface which is increased by roughly 25% without being heavier or possessing less resistance to twisting.

Description

Die Erfindung betrifft eine Saitenaufhängungskonstruktion zur Vergrößerung der freischwingenden Bespannungsfläche eines Ballspielschlägers.The invention relates to a string suspension construction for Enlargement of the free-swinging covering area Ball game racket.

Ballspielschlägerrahmen haben die Funktion eine Saite, die ein Geflecht bildet, das den Kontakt und die Kraftübertragung zum Spielball übernimmt, aufzunehmen.Ball game racket frames have a function String that forms a braid, that the contact and the Power transmission to the game ball takes over.

Die nutzbare Spielfläche ist proportional zur Saitengeflechtgröße, jedoch erheblich kleiner als diese. Da heutige Schlägerkonstruktionen Saitenbohrungen aufweisen, die entweder zu zentralen Punkten innerhalb der Bespannungsflä­ che weisen, oder rechtwinklig zur Tangente der Rahmenaußen­ seite ausgerichtet sind, liegen die Saiten auf der Rahmenin­ nenseite an. Diese Konstruktion begründet sich in der massi­ ven Holzrahmenbauweise, da Bohrungen in Geflechtrichtung die Saite beim Vibrieren touchieren und negative Geräusche erzeu­ gen. Die wirksame Länge der Saite reicht bei heutigen Kon­ struktionen von Rahmeninnenseite zur Rahmeninnenseite. Um einen Schläger mit größerer nutzbarer Spielfläche zu erhalten mußte der Rahmen vergrößert werden. Es entstanden die soge­ nannten Midsize- und Oversizerahmen.The usable playing area is proportional to String braid size, but significantly smaller than this. There today's racket designs have string holes that either to central points within the covering area che point, or perpendicular to the tangent of the frame outer the strings are on the frame side. This construction is based on the massi ven wooden frame construction, as holes in the braid direction the Touch the string when vibrating and generate negative noises The effective length of the string is sufficient for today's con structures from the inside of the frame to the inside of the frame. Around to get a racket with a larger usable playing area the frame had to be enlarged. The so-called called midsize and oversize frames.

Der Erfindung liegt die Aufgabe zugrunde, die nutzbare Spielfläche innerhalb des Schlägerrahmens so groß wie möglich zu gestalten.The invention has for its object the usable Play area within the racket frame as large as possible to design.

Diese Aufgabe wird in einem hohlen Rahmenprofil da­ durch gelöst, daß die Saitendurchlässe auf der Rahmenaußen­ seite kleiner als auf der Rahmenaußenseite sind und in Sai­ tenflucht angeordnet sind. Die Saiten liegen bei dieser Kon­ struktion auch unter Last nur auf der Rahmenaußenseite an.This task is there in a hollow frame profile solved by that the string passages on the frame outside side are smaller than on the outside of the frame and in Sai  tenflucht are arranged. The strings are with this Kon structure only under load on the outside of the frame.

Die mit der Erfindung erzielten Vorteile bestehen ins­ besondere darin, daß in einem Rahmen eine ca. 25% größere, freischwingende Bespannungsfläche befestigt werden kann. So­ mit den Spielvorteil eines größeren Rahmens bietet, ohne des­ sen Nachteile, entweder höheres Gewicht oder geringere Verwindungssteifheit akzeptieren zu müssen.The advantages achieved by the invention are special in that in a frame an approx. 25% larger, free-swinging covering surface can be attached. Like this with the game advantage of a larger frame, without the Disadvantages, either higher weight or lower Having to accept torsional stiffness.

Die Erfindung einer Saitenaufhängungskonstruktion dient zur Vergrößerung der freischwingenden Bespannungsfläche eines Ballspielschlägers, dadurch gekennzeichnet, daß die Saiten nur an der Außenwand des Hohlrahmens anliegen, da die Austrittsöffnungen auf der Innenseite des Rahmens so groß di­ mensioniert sind, daß die Saiten auch unter Last die Innen­ seite des Rahmens nicht berühren.The invention of a string suspension construction serves to enlarge the free-swinging covering surface of a ball game racket, characterized in that the strings only rest on the outer wall of the hollow frame, since the outlet openings on the inside of the frame are dimensioned so large that the strings also load the inner side do not touch the frame.
