KAISERLICHES A IMPERIAL A
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft die Herstellung von Schlägern oder Schlagnetzen für Tennis und ähnliche Ballspiele.The present invention relates to the manufacture of rackets or rackets for tennis and similar ball games.
Bei derartigen Schlägern oder Schlagnetzen wird der aus Holz gebogene Rahmen mit dem
zwischen seine Schenkel eingeführten Mittelstück oder Keil in der Regel durch Leim oder
dergl. verbunden und diese Verbindung außerdem durch Schrauben verstärkt, oder es werden,
um das Losewerden und Verschieben des Keiles in Querrichtung zu verhüten, beide Teile ineinander gefugt. Gegenüber beiden
Verbindungsarten aber werden gemäß vorliegender Erfindung wesentliche Vorteile erzielt.
Nach derselben sind die Anlage- oder Berührungsflächen beider Teile, des Mittelkeiles
und des Rahmens, mit Nuten versehen, in die eine die Verbindung der beiden Schlä'gerteile
bewirkende Doppelfeder eingreift.
In der Zeichnung ist:In such rackets or batting nets, the bent wooden frame is usually connected to the middle piece or wedge inserted between its legs by glue or the like. This connection is also reinforced by screws, or it is made to loosen and move the wedge in the transverse direction to prevent both parts joined together. Compared to both types of connection, however, essential advantages are achieved according to the present invention. According to the same, the contact or contact surfaces of both parts, the central wedge and the frame, are provided with grooves in which a double spring engages the connection of the two racket parts.
In the drawing is:
Fig. ι die Ansicht eines gemäß der Erfindung zusammengefugten unbespannten Schlägers,Fig. Ι the view of an unstrung racket joined together according to the invention,
Fig. 2 ein Schnitt nach der Linie 1-2 der Fig. ι undFig. 2 is a section along the line 1-2 of Fig. Ι and
Fig. 3 ein Schnitt nach der Linie 3-4 von Fig. i.Fig. 3 is a section along the line 3-4 of Fig. I.
Der das Netz aufnehmende Rahmen a des Schlägers ist in der üblichen Weise aus Holz gebogen und umschließt mit seinen Schenkeln das Mittelstück oder den Keil b. In die Anlage- oder Berührungsflächen beider Teile, des Rahmens α sowohl als auch des Keiles b, sind Nuten eingeschnitten, derart, daß zwischen beide Teile zwei in beide Nuten eingreifende Doppelfedern d eingelegt werden können, die eine feste Verbindung zwischen den Schlägerteilen herstellen und insbesondere den Mittelkeil gegen Querverschiebung sichern. The frame a of the racket that receives the net is bent from wood in the usual way and encloses the center piece or the wedge b with its legs. In the contact or contact surfaces of both parts, the frame α as well as the wedge b, grooves are cut so that two double springs d engaging in both grooves can be inserted between the two parts, which establish a firm connection between the racket parts and in particular Secure the central wedge against lateral displacement.
Diese Art der Verbindung ermöglicht, den Rahmen auch aus weniger gutem und geradfaserigem Material leichter und mit verminderter Gefahr eines Bruches oder Springens zu biegen und vereinfacht überdies die Herstellung des Schlägers.This type of connection allows the frame to be made from less good and straight grain To bend material more easily and with less risk of breakage or cracking and also simplifies the manufacture of the racket.
