Abstract (en)
A twisted tennis racket frame (10) includes a handle (20), two supporting arms (30) having outside surfaces (32) facing reverse directions, and an annular-shaped head (40) provided on an imaginary plane (50) with large and small arc portions (41, 45). The large arc portion (41) has an external arc surface (43), which composes a continuous curved surface (60) with the outside surfaces (32) of the two supporting arms (30). The continuous curved surface (60) has at least one twisted section (70) having a starting end (71) located at the large arc portion (41) and faces toward a first facing direction (81) that is situated on the imaginary plane (50), and a terminal end (72) connected with the handle (20) and faces toward a second facing direction (82). The included angle between the first and second facing directions (81, 82) is larger than 0 degree and not larger than 180 degrees. As a result, the racket performs well in controlling the ball and enables the user to turn the hitting surface quickly.
