发明名称 Tennis racket and stringing method
摘要 A tennis racket head is strung with string sections between frame support points formed into zig-zag segments which have multiple junction points with other string sections to hold the strings in the zig-zag pattern. In a preferred embodiment, the segments are arranged in parallel tiers, and weave over and under intermediate strings between junctions. An apparatus and method for stringing the racket is included. A simple tension adjustment can be added to the racket, which adjusts the tension over the entire playing surface.
