发明名称 Reinforcing member for a badminton racquet
摘要 A reinforcing member for a badminton racquet wherein the racquet extends along a longitudinal axis and includes a frame having a tubular hoop portion supporting a string bed and a tubular handle portion. The reinforcing member includes a generally T-shaped body having first and second sections. The first section has an outer surface that defines a first cross-sectional area measured about a longitudinal plane positioned generally perpendicular to the string bed. The second section longitudinally and outwardly extends from the first section. The second section has an outer surface that defines a second cross-sectional area measured about a transverse plane. The first cross-sectional area is at least 50 percent greater than the second cross-sectional area. The first and second sections are configured for placement within the hoop and handle portions of the frame, respectively.
