Abstract

A yo-yo includes a pair of body halves connected to a hub assembly about an axis of rotation. Each body half includes an outer ring positioned between an outside plate and an inside plate, where the inside plate on each body half is positioned to face the hub assembly. The outer ring has an annular projection extending inwardly along an interior surface, and has a lip defined along one edge of the outer ring. The outside plate and inside plate includes grooves that when assembled inside the outer ring form an annular opening about the annular projection. The outside plate also includes a notch defined along one edge of the outside plate and positioned to receive the lip of the outer ring when the outside plate is positioned within the outer ring. The inside plate further has a recess positioned on a surface that faces the hub assembly. The recess has a shape substantially identical to a hub shape defined by a portion of the hub assembly such that when assembled, the portion of the hub assembly is positioned within the recess. The yo-yo being capable of being disassembled such that the outer ring, inside plate, outside plate and hub assembly may be interchangeable with different outer rings with various weights than the original outer ring, as well as replace the inside plate, outside plate and hub assembly.
