Beschreibung :Description :

Bei Tennisschlägern der üblichen Bauart zeigt sich der tJbelstand, daß die Bespannung nach einer gewissen Benutzungsdauer durch Längenausdehnung der Sehnen die Vorspannung verliert. Ein Nachspannen durch den Benutzer ist bisher nicht möglich,die Bespannung muß kostenaufwendig erneuert werden. Der Neuerung liegt die Aufgabe zugrunde, die Lebensdauer der Bespannung zu verlängern,sowie die Vorspannung der dehnen individiAell auf die Bedürfnisse des Benutzers und die Plat »Verhältnis se einzustellen.The problem with tennis rackets of the usual design is that the strings lose their pre-tension after a certain period of use due to the lengthening of the strings. Re-tensioning by the user is not yet possible, the strings have to be replaced at great expense. The innovation is based on the task of extending the life of the strings and adjusting the pre-tension of the strings individually to the needs of the user and the pitch ratio.

Die Neuerung bestellt darin,die Sehnen mittels einer ...pannvorrichtungjdie sich am oberen Ende des GriffStückes befindet,nachzuspannen. The innovation is to re-tension the strings using a tensioning device that is located at the top of the handle.

) tiber Rollen,die am Umfang des Schlägers angebracht sind,werden die Sehnen gezogen bzw.umgelenkt.) The strings are pulled or redirected via rollers that are attached to the circumference of the racket.

Die Spannvorrichtung besteht aus einem Rollenhalter mit Gewindestift und Spannmutter.The clamping device consists of a roller holder with threaded pin and clamping nut.

Die Spannmutter sitzt in einem Widerlager.The clamping nut sits in an abutment.

Durch drehen, der Spannmutter wird der Rollenhalter mittels Gewindestift in Richtung der Spannmutter gezogen,wodurch die Spannung der Sehnen erhöht wird.By turning the tensioning nut, the roller holder is pulled towards the tensioning nut using a threaded pin, which increases the tension of the tendons.

Auf der Zeichnung ist die Neuerung dargestellt,und zwar stellt Abb. 1 den Schläger im Schnitt mit Bespannung,Spannvorrichtung, Widerlager und die am Umfang angebrachten Rollen dar, Abb. 2 den Schläger im Schnitt um 90° gedreht ohne Bespannung, mit Spannvorrichtung,Widerlager und einer Rolle, In der Abb. 1 und 2 bezeichnet 1 den Rollenhalter mit zwei Rollen, 2 den Gewindestift, 3 das Widerlager, 4 die Spannmutter,5 die Rollen am Umfang des Schlägers, 6 die Rollenlagerung, Sämtliche Rollen haben am Umfang eine Rille zwecks besserer i-tihrung der Sehne,
bpannvorrichtung besteht aus Teil 1 - 4 und 6 .The innovation is shown in the drawing, namely Fig. 1 shows the racket in section with stringing, tensioning device, abutment and the rollers attached to the circumference, Fig. 2 shows the racket in section rotated by 90° without stringing, with tensioning device, abutment and one roller, In Fig. 1 and 2, 1 designates the roller holder with two rollers, 2 the threaded pin, 3 the abutment, 4 the tension nut, 5 the rollers on the circumference of the racket, 6 the roller bearing, All rollers have a groove on the circumference for better guidance of the string,
The tensioning device consists of parts 1 - 4 and 6.
