Metallrahmen für TennisschlägerMetal frame for tennis rackets
Es ist bekannt, dass Ballschläger mit Metallrahmen Vorteile inbezug auf leichtes Gewicht und Verformungswiderstand aufweisen und dass lediglich ihr verhältnismässig hoher Gestehungspreis bisher ihre HändeIsfähigkeit einschränkte.It is known that rackets with metal frames have advantages in terms of light weight and resistance to deformation and that only their relatively high cost price has so far been their ability to handle restricted.
Um diesen Nachteil zu beheben, richtet sich die Erfindung auf einen Metallrahmen für Ballschläger, der in Grossserien besonders wirtschaftlich hergestellt werden kann In order to remedy this disadvantage, the invention is directed to a metal frame for rackets, which can be produced particularly economically in large series

und dessen Verwendungsmerkmale denen der bekannten Metallrahmen vollkommen vergleichbar sind.and its features of use are completely comparable to those of the known metal frames.
Der Rahmen nach der Erfindung ist dadurch gekennzeichnet, dass er aus zwei auf das übliche Profil gebogenen Metallrohrteilen besteht, von denen mindestens eines auf seiner Seitenwand Eindrücke oder Vertiefungen aufweist, die, sobald die erwähnten Metallrohrteile zusammengesetzt sind, zwischen diesen freie Räume für den Durchtritt und das Festhalten von Quer- und Längsverspannungen des Seilwerks begrenzen.The frame according to the invention is characterized in that that it consists of two metal tube parts bent to the usual profile exists, at least one of which has indentations or depressions on its side wall, which, as soon as the mentioned metal pipe parts are assembled, free spaces for the passage and between them limit the retention of transverse and longitudinal tension in the rope system.
Nach einem bevorzugten Ausführungs-Beispiel der vorstehenden Anordnung beginnt man mit dem Verbiegen der beiden Rohrteile auf das übliche Profil, worauf sie beide einem Stanzvorgang unterzogen werden, um Eindrücke oder Vertiefungen auf ihren einander gegenüberstehenden Wänden einzuprägen. Schliesslich werden sie durch Löten oder Schweissen zusammengesetzt, wobei dafür Sorge zu tragen ist, dass die Vertiefungen der beiden Teile übereinander zu liegen kommen.According to a preferred embodiment of the above arrangement, one begins with the bending of the both pipe parts to the usual profile, whereupon they are both subjected to a punching process to produce impressions or emboss depressions on their opposing walls. Finally they are made by soldering or welding, taking care that the depressions of the two parts come to lie on top of each other.
Die beigefügte Zeichnung veranschaulicht beispielshalber zwecks besseren Verständnisses die Erfindung und zwar zeigtThe accompanying drawing illustrates by way of example for the purpose of a better understanding of the invention, namely shows

Fig.7 und 8 Ansichten entsprechend Fig.4 und 6, jedoch zu einer abgewandelten Ausführungsform der Erfindung. 7 and 8 are views corresponding to FIGS. 4 and 6, however to a modified embodiment of the invention.
Wie eingangs angegeben, beginnt man zur Herstellung eines Metallrahmens für Tennis- oder dgl. Schläger mit dem Zuschneiden eines Metallrohrstückes auf bestimmte Längen, sodass zwei geradlinige Teile anfallen. Diese werden sodann einem Verformungsvorgang unterzogen, damit sie die übliche Biegung nach Fig.l und einen Teil 1 mit im wesentlichen ■ rundem Profil zur Aufnahme der üblichen Verspannungen, sowie zwei geradlinige Verlängerungen 2 aufweisen, die zueinander parallel zwecks Bildung des Handgriffes gerichtet sind.As stated at the outset, you begin to produce a metal frame for tennis rackets or the like. With the cutting a piece of metal pipe to certain lengths, so that two straight parts are produced. These are then subjected to a deformation process to make them the usual Bend according to Fig.l and a part 1 with an essentially ■ round profile to accommodate the usual tension, as well as two straight extensions 2, which are directed parallel to one another for the purpose of forming the handle are.
Der Teil 1 jedes der beiden so erhaltenen Bestandteile wird sodann einem Stanzvorgang zur Ausführung der Eindrücke 3 (Fig.3 und 5) auf der Seitenwand des Teiles in geeignetem Abstand voneinander unterzogen, wobei dieseThe part 1 of each of the two components thus obtained is then a punching process to carry out the Impressions 3 (Fig.3 and 5) on the side wall of the part subjected to a suitable distance from each other, these
309886/0444309886/0444
Abstände regelmässig, je nach, der für den zu schaffenden Rahmen vorgesehenen Bespannung, sein können.Intervals regularly, depending on the one to be created Frame provided covering, can be.
Nach, dem Stanzen werden die beiden Bestandteile übereinander angeordnet, sodass die Vertiefungen 3 einander gegenüber zu stehen kommen. Es genügt dann, diese Bestandteile, beispielsweise durch, eine Lot- oder Schweissnaht 4 (Fig.4 und 6) zusammenzusetzen. Wie jetzt erkennbar ist, bilden die einander gegenüberstehenden Vertiefungen (Eindrücke) 3 öffnungen 5 für den Durchtritt der Quer- und Längsbespannimgen.After the punching, the two components are on top of each other arranged so that the depressions 3 come to face each other. It is then sufficient to have these components, for example, by assembling a solder or weld seam 4 (FIGS. 4 and 6). As can be seen now is, form the opposing depressions (impressions) 3 openings 5 for the passage the cross and lengthways covering.
Wie in Fig. 7 und 8 wiedergegeben ist, können sich die in .den einen und anderen der beiden Rohrteile gearbeiteten Vertiefungen auf erhebliche Länge erstrecken, sodass sie längliche öffnungen 5' für den Durchtritt mehrerer BespannungsstrSnge bilden, die dann durch Lochungen 6a eines Distanzstückes oder einer Platte aus Kunststoff 6 festgehalten werden, das bzw. die am Äussenprofil des eigentlichen Rahmens angebracht ist,As shown in FIGS. 7 and 8, the in .worked one and the other of the two pipe parts Depressions extend over a considerable length, so that they have elongated openings 5 'for the passage of several strings form, which then through holes 6a of a spacer or a plate made of plastic 6 that is attached to the outer profile of the actual frame,
Es ergibt, sich, dass die in den beiden den Rahmen bildenden Rohrteilan vorgesehenen Eindrücke 3 unterschiedliche Tiefen aufweisen können; in bestimmten Fällen brav :iit nur einer der beiden Bestandteile die Eindrücke aufzuweisen, während die Wand des anderen glatt bleibenIt turns out that those in the two form the framework Pipe part at the provided impressions 3 different May have depths; in certain cases good: only one of the two components is the impressions while the wall of the other remains smooth
