Finger twirled toy with balancing mass
摘要:
A toy adapted to be twirled on the finger of a user. The toy has a manipulating ring adapted to encircle the finger of the user of the toy, a connector extending from the manipulating ring for a selected distance, a substantially ring-shaped pedestal holder connected to the connector at a point remote from the primary manipulating ring, and a substantially spherical pedestal attached to the pedestal holder at a point substantially facing the manipulating ring. A balancing mass is adapted to balance on the pedestal, and a retaining loop is fastened to the balancing mass and looped through the pedestal holder, whereby the balancing mass is prevented from falling free from the toy when it is not balanced on the pedestal. A user places the balancing mass on the pedestal and twirls the toy without disturbing the balancing mass, which is held in place by centrifugal force.
