发明名称 Yo-yo having radially anchored cushions, and a string gap with a narrower innermost gap
摘要 A yo-yo comprising right and left bodies surrounded by thick, radially anchored, soft rubber outer cushions has a string gap having a contour that includes an innermost gap which is narrower than other regions of the string gap. The string gap may have a narrowed neck region located between the innermost gap and the outer diameter of the yo-yo. The yo-yo may include an axle which is permitted to rotate within the left body of the yo-yo but retained by a locknut seated in the right body of the yo-yo.
