ABSTRACT:
A conventional sports racket is disclosed as having interwoven string systems in its string network whose midplane coincides with the midplane of the frame of the racket, wherein strings of one system which are approximately parallel among themselves are meshing with strings of other systems in large oblique angles at respective string joints where one string in one string system crosses over a string of another system under axial tension force. The invention includes at least having one string fixer, installed in a string joint, having interlocking legs arranged to exert compressive force to the strings from either side of the string network towards the midplane, or other ring typed device based on the same principle, which reduces sliding between the contacting strings from the impact of the ball on the string network of the racket. Also, is a string fixer which does not contact the ball when it hits the joint.
