ABSTRACT:
A mechanism for adjusting string tension of stringed rackets allows for increasing the tension of the racket strings without having to release the racket strings, without destabilizing the racket and without costly or troublesome aids. The tensioning mechanism includes an abutment piece and a tensioning piece. Strings of the racket pass through both pieces. The tensioning piece is lockable in varying positions to increase string tension. When the racket is strung, the mechanism can be arranged in a position of least tension. In that case, if the string tension declines, the tightening mechanism can be adjusted to a position of the next highest racket tension. Alternatively, the mechanism can be initially set to a medium tension setting and subsequently adjusted as appropriate.
