Patent ID: 7192330

Claim:
A yo-yo comprising: first and second side members secured together in a spaced-apart relation by an axle structure; a tether secured to a portion of said axle structure; and wherein said first side member includes a body portion that has an inwardly-facing surface that faces toward said tether and an outwardly-facing surface that faces away from said tether, wherein said first side member also includes a shuttle and an adjustment nut, wherein said shuttle includes a tether-facing portion having a tether engagement surface capable of engaging said tether, wherein said shuttle is movably secured to said body portion by said adjustment nut, wherein said adjustment nut is rotatably fixed on said body portion, wherein said adjustment nut is rotatably engaged to said shuttle in a manner whereby when said shuttle is in a first position, rotation of said nut in a first direction pushes on, and thereby moves, said shuttle to a second position in which the shuttle's tether engagement surface is located closer to said tether, and wherein if said shuttle is in said second position and said nut is rotated in a second, opposite direction, said nut pulls on, and thereby moves, said shuttle in a manner whereby the shuttle's tether engagement surface moves away from said tether.
