US Patent 9132322 Tennis racket

A tennis racket including a shaft that has a handle and a head attached thereto having a diamond-shaped frame. A length dimension of the frame is longer than a width thereof and is parallel to the shaft. A string groove is continuously disposed around the frame. A plurality of string holes is disposed within the string groove. A single length of string is continuously disposed through the string holes to string the tennis racket. A pair of tie off members is centrally disposed within the string groove on one side of the frame proximal a first corner of the frame. A central portion of the string centrally disposed within the frame forms a sweet spot which is larger than the sweet spots of other tennis rackets due to the diamond shape of the frame thereby propelling the tennis ball with more power and a more accurate aim.
