Abstract: A racket for ball games may include a frame which is formed by a frame profile or a hollow profile and has a racket head and a handle portion connected thereto preferably via a heart region. Two indentations that are symmetrical relative to the longitudinal axis of the racket may be provided in the heart region of the frame. A vibrating device may be arranged in each of the two indentations. The vibrating means of the racket may preferably be effective for vibrations having at least two vibration modes or degrees of freedom. Additionally or alternatively, a racket for ball games may include a frame which forms a head region for receiving strings and a handle portion for holding the racket. The frame may include one respective inwardly-facing C-profile in at least two segments of the head region.

Abstract: The present disclosure relates to a string for a ball game racket including at least two parallel filaments, wherein only portions of the filaments are interconnected. Moreover, the disclosure relates to method of producing such a string. A first method includes the steps of providing at least two string filaments, bringing the string filaments together into a parallel configuration and combining portions of the string filaments. An alternative production method includes the steps of providing a string and slitting portions of the string so as to produce at least two parallel filaments of the string, only portions of which are interconnected.

Abstract: The racket (2) for ball games of the present invention comprises a frame which is formed by a frame profile or a hollow profile and has a racket head and a handle portion connected thereto preferably via a heart region. Two indentations (12) that are symmetrical relative to the longitudinal axis of the racket are provided in the heart region of the frame. A vibrating device (20) is arranged in each of the two indentations. The vibrating means of the racket of the present invention are preferably effective for vibrations having at least two vibration modes or degrees of freedom. The invention further relates to a racket for ball games comprising a frame which forms a head region for receiving strings and a handle portion for holding the racket, wherein the frame comprises one respective inwardly-facing C-profile in at least two segments of the head region.
