Abstract

The tennis racket device comprises a tennis racket with rotational bodies with eccentric shapes. The rotational bodies are movably mounted on individual strings with an eccentric weight distribution. The rotational bodies are also arranged inside and outside of the hollow tennis frame. The rotational bodies are composed of two different materials, one of which is a heavy metal. It is the difference in the material weight that causes the eccentric weight distribution.

Description

Vorrichtung an Schlägern für Ballspiele zur Erhöhung des Schwung- und Schlagkraft und Minderung des Rückschlagimpulses durch Rotationskörper mit exzentrischer Gewichtsver­ teilung.Device on rackets for ball games to increase the momentum and power Reduction of the kickback impulse by rotating body with eccentric weight division.

Die Erfindung betrifft eine Vorrichtung, nach Anspruch 1 Rotationskörper genannt, welche freischwingend an den einzelnen Saiten angebracht wird. Die exzentrische Gewichtsvertei­ lung an den Rotationskörpern bewirkt beim Auftreffen des Schlagballes auf die Bespan­ nung und der Verzögerung, welche der Schläger dann erfährt, ein Rotieren der Rotations­ körperschwerpunktes in Schlagrichtung. Dabei geben die Rotationskörper einen Teil ihrer kinetischen Energie an die einzelnen Saiten der Bespannung ab und bewirken eine zusätz­ liche Beschleunigung des Schlagballes. Zugleich wird der Rückschlagimpuls gemindert.The invention relates to a device, called according to claim 1, which cantilever is attached to the individual strings. The eccentric weight distribution The effect on the rotating bodies is when the striking ball hits the covering voltage and the delay which the racket then experiences, a rotation of the rotation center of gravity in the direction of impact. The rotating bodies give part of theirs kinetic energy on the individual strings of the covering and cause an additional acceleration of the striking ball. At the same time, the kickback pulse is reduced.

Die Rotationskörper können im Innern des hohlen Schlägerrahmens oder an der Innenseite des ovalen Schlägerrahmens an den Saiten der Bespannung angebracht werden. Die Durchgangslöcher im Schlägerrahmen müssen an der Innenseite als Langlöcher aus­ gebildet sein, um das Schwingen der Saitenbespannung zu ermöglichen.The rotating bodies can be inside the hollow racket frame or on the inside of the oval racket frame on the strings of the covering. The through holes in the racket frame must be elongated on the inside be formed to allow the string stringing to swing.

Die Rotationskörper können aus 2 verschiedenen Werkstoffen gefertigt werden, wobei der schwerere Werkstoff, günstig sind alle Schwermetalle, die exzentrische Gewichtsverteilung bewirkt. Bei exzentrischen Rotationskörpern kann allein durch die Form die exzentrische Gewichtsverteilung bewirkt werden.The rotating body can be made of 2 different materials, the heavier material, cheap are all heavy metals, the eccentric weight distribution causes. In the case of eccentric rotating bodies, the eccentric can be achieved solely through the shape Weight distribution can be effected.

Der Erfindung liegt die Aufgabe zugrunde, höhere Schlagkraft und geringere Rückschla­ gimpulse bei Ballspielen mit Handschlägern zu bewirken. The invention has for its object higher power and less kickback to effect gimpulse in ball games with hand rackets.
