Description
Das Griffenide der Tennisschläger ist mit dem Rahmeribügel federnd verbunden, damit beim Aufschlagen des Spielballes die Netzsaiten des Rahmenbügels einen besseren Schutz gegen Zerreißen finden.The handle side of the tennis racket is resiliently connected to the frame bar, so when hitting the ball, the net strings of the frame bracket a better one Find protection against tearing.
Der so gemilderte Aufprall des Spielballes wirkt außerdem weniger ermüdend auf den Arm des Spielers.The so reduced impact of the game ball also has a less tiring effect on the Arm of the player.
Bei den bekannten Ballschlagern ist zwarIn the case of the known ball hitters, it is true
ίο dieses federnde Stück mehr oder weniger vorhanden, aber überall noch mangelhaft und unvollkommen ausgebildet.ίο this springy piece more or less present, but still insufficiently and imperfectly developed everywhere.
Der Unterschied der federnden Ausbiegungsbewegung bei den beiden Schlägerarten
tritt besonders hervor, wenn der Spielball nicht die Mitte der Schlagflächen trifft, sondern
am Kopfende, wie es Abb. 3 bei f für einen der 'bisher gebräuchlichen Tennisschläger
veranschaulicht, oder wenn er den unteren Teil bei g trifft. Die Ruhelage zeigen die
punktierten Linien, und die Abstände der beiden Punkte bei f und g von der Ruhelagelinie
weisen einen sehr großen Unterschied auf.
Es ist deshalb ohne weiteres klar, daß auch die Wirkung eine sehr verschiedene sein muß.
Die vorliegende Erfindung beseitigt nun diesen Fehler; sie bietet dabei den Vorzug, daß
die Federung sehr ausgiebig ist, sowie beliebig weich oder hart gemacht werden kann
bei großer Stabilität und Leichtigkeit, die in anderer Art kaum erreichbar erscheint.The difference in the resilient flexing movement of the two types of racket is particularly evident when the ball does not hit the center of the clubface, but at the head end, as illustrated in Fig. 3 at f for one of the tennis rackets commonly used up to now, or when it hits the lower part g hits. The rest position is shown by the dotted lines, and the distances between the two points at f and g from the rest position line show a very large difference.
It is therefore immediately clear that the effect must also be very different. The present invention now eliminates this flaw; it has the advantage that the suspension is very extensive, and can be made soft or hard as desired, with great stability and lightness that hardly appears to be achievable in any other way.
Die Zeichnung stellt beispielsweise einen Ballschläger dar, der aus Metall gefertigt ist, doch ist die Ausführung an keine Materialart gebunden.For example, the drawing shows a racket made of metal, but the execution is not tied to any type of material.
In Abb. ι der Zeichnung soll α der Handgriff sein, b der Rahmenbügel, in weichen die Netzsaiten c verspann* sind; d und ei1 ist die federnde Verbindung für das Griffende, der Gegenstand der Erfindung.In Fig. Ι of the drawing, α should be the handle, b the frame bracket, in which the net strings c are braced; d and ei 1 is the resilient connection for the handle end, the subject of the invention.
Diese federnde Verbindung g besteht aus mindestens zwei mit Abstand voneinandergelagerten Blattfedern, die in Abb. 2 in Seitenansicht dargestellt sind bei d und d1. This resilient connection g consists of at least two leaf springs mounted at a distance from one another, which are shown in side view in Fig. 2 at d and d 1 .
Die punktierten Linien in Abb. 2 stellen den Ausschlag der Parallelf ederung beim Aufprallen des Spielballes dar.The dotted lines in Fig. 2 represent the deflection of the parallel spring deflection on impact of the cue ball.
Der fensterartige Zwischenraum von d bis c?1 kann auch durch beliebig viele weitere Federblätter ausgefüllt sein. Dabei bleibt stets als Hauptbedingung, daß sämtliche Blattfedern an beiden Enden feste Verbindung haben, die keine Verschiebung gestatten, da nur auf diese Art die Parallelfederung in Verbindung mit großer Leichtigkeit und Stabilität erzielt wird.The window-like space from d to c? 1 can also be filled in with any number of other spring leaves. The main condition always remains that all leaf springs have a fixed connection at both ends that do not allow any displacement, since only in this way the parallel suspension is achieved in connection with great lightness and stability.
Es können auch mehrere auf diese Weise gebildete Federgruppen in einer Kette hintereinander oder nebeneinander angeordnet sein.It is also possible for several spring groups formed in this way in a chain one behind the other or be arranged side by side.
