Die Erfindung bezieht sich auf Saitenschutzteilchen für eine Tennisschlägerbespannung, weiche an den Oberkreuzungsstellen der Saiten und zwischen den Saiten angeordnet sind, und welche die Saiten aufnehmende Rillen aufweisen. .The invention relates to string protection particles for a tennis racket covering, soft to the Crossing points of the strings and between the strings are arranged, and which the strings receiving Have grooves. .

Die bekannten verflochtenen Schlägerbespannungen haben nur eine begrenzte Haltbarkeit, was besonders bei teuren Darmsaiten sehr kostspielig isL Die Lebensdauer der Saiten soll durch Saitenschutzteilchen merklich vergrößert werden.The well-known intertwined racket strings have only a limited shelf life, which is special very expensive with expensive gut strings isL The service life of the strings should be noticeable due to string protection particles be enlarged.

Es ist bereits bekannt (CH-PS 5 70 176), Saitenschutzteilchen der eingangs genannten Art in Form von Kreuzteilchen mit Rillen zur Aufnahme der sich kreuzenden Saiten zwischen die Saiten zu klemmen. Da jedoch der Aufdruck der Saiten aufeinander an den Überkreuzungen bedingt durch die Verflechtung und durch den Aafdruck des Balles sehr groß ist, wird durch die genannten Teilchen der Abriea und somit die Zerstörung der Saiten nur unbefriedigend verringert, auch wenn dort schon der zur Herstellung der Teilchen verwendete Kunststoff reibungsarm und selbstschmierend sein soll. Die Saiten zerstören sich nicht mehr durch Reibung aufeinander sondern durch Reibung an den Saitenschutzteilchen.It is already known (CH-PS 5 70 176), string protection particles of the type mentioned at the outset in the form of cross-shaped particles with grooves to accommodate the intersecting ones To clamp the strings between the strings. However, there is the imprint of the strings on top of each other at the crossovers due to the interweaving and the pressure of the ball is very large, is due to the called particles of the Abriea and thus the destruction of the strings only unsatisfactorily decreased, too if the plastic used to manufacture the particles is low-friction and self-lubricating should be. The strings are no longer destroyed by rubbing against each other but by rubbing against the String protection particles.

Die der Erfindung zugrunde liegende Aufgabe besteht daher darin, Saitenschutzteilchen der eingangs genannten Art zu schaffen, welche den Saitenverschleiß durch Reibung aneinander oder durch Reibung an den Saitenschutzteilchen wirkungsvoll verringert.The object on which the invention is based is therefore to provide string protection particles of the type mentioned at the beginning Art to create, which the string wear by friction against each other or by friction against the Effectively reduced string protection particles.

Diese Aufgabe wird dadurch gelöst, daß der Boden der Rillen mindestens eine Vertiefung zur Aufnahme eines Schmiermittels aufweist.This object is achieved in that the bottom of the grooves has at least one recess for receiving it of a lubricant.

Wenn die Rillenbreite dem Saitendurchmesser angepaßt ist, so dichtet die Saite (2,3) die Vertiefung (5) ab, ähnlich einem Kolben im Zylinder. Dadurch reicht das Schmiermittel in der Vertiefung (5) lange Zeit, um die Saite (2, 3) zu schmieren und den frühzeitigen Verschleiß der Saite durch Abrieb zu verhindern. Damit die Saitenschutzteilchen (1) nicht zu sehr auftragen, ist es günstig, zwei Vertiefungen (5) zwischen Rillenboden (4) und Schenkel der Rille (X, 3') auszubilden (vgl. dazu die Zeichnung).When the groove width is adapted to the string diameter, the string (2, 3) seals the recess (5), similar to a piston in the cylinder. As a result, the lubricant in the recess (5) lasts for a long time to lubricate the string (2, 3) and to prevent the string from premature wear due to abrasion. So that the string protection particles (1) do not apply too much, it is advantageous to form two depressions (5) between the groove bottom (4) and the leg of the groove (X, 3 ') (cf. the drawing).
