A prefabricated tuned top and a launcher for launching the tuned top, manufactured in a small size with five components of a knob, a rim, beads, a body and a spinning spindle. The tuned top can be readily assembled by sequentially inserting and then tightening the components. The tuned top implements a changeable spinning form based on induction of a change in difference between the centripetal force and centrifugal force, generated during spinning, since the center of gravity can be eccentrically disposed freely according to the user's selection. The tuned top is prevented from being reversely loosened so it can be safely, semi-permanently, and easily enjoyable at any location. The tuned top enables accurate and stable mounting when a launcher is used, such that the top is not easily separated therefrom but is quickly launched without a launch failure, thereby providing accurate launching without the loss of spinning power.

A first locking mechanism is configured to block rotating the first and second holders by locking an operation component or by locking the first and second holders when the cap is not mounted on one of the first and second holders, and is configured to unlock rotating the first and second holders by being engaged with the cap when the cap is mounted on one of the first and second holders and when the cap is arranged to face upwardly towards a upper side. A second locking mechanism is configured to block rotating the first and second holders by locking the operation component or by locking the first and second holders when the cap is mounted on one of the first and second holders and when the cap is arranged to face downwardly to a lower side opposite to the upper side.

A spinning top toy for spinning on a surface includes a shaft part and a body. The shaft part includes a shaft part body and a ground contact part being integrally formed with the shaft part body. The shaft part extends in an axial direction. The body is configured on the shaft part. The ground contact part includes a wheel-shaped body being slidably configured on the shaft part body. The wheel-shaped body is configured to be moved to a first position, and is configured to be moved to a second position. The second position is closer to the surface than the second position in the axial direction. The wheel-shaped body is configured to be in contact with the surface when at the second position.

The string launched flexible rolling wheel or Sling Wheel is used for recreational play. The Sling Wheel is a flexible, 5 to 10-inch diameter disc/wheel that has a deep slot in which to wind a length of string with a knot or a device with which to grip or otherwise attach to the finger(s) or hand. The end of the string without the knot or handle is wound in the slot a number of turns. After the string is wound, the Sling Wheel is tossed in an underhand or overhand motion while keeping the string knot firmly grasped. The Sling Wheel spins away from the participant with a forward spin that gives it directional control and significant velocity. The string remains with the person launching the toy.

The spinning top launching device includes a rotary drive mechanism being configured to be rotated by the operation member and configured to apply rotary force to the spinning top, a rotation speed detection mechanism including a centrifugal clutch mechanism being configured to be rotated by the operation member, and an operation body being engaged with an output side of the centrifugal clutch mechanism to be moved in a first direction from a predetermined position. The operation body includes an indication part configured to indicate the rotation speed.

A gyroscope includes a frame that surrounds a wheel and a weight that is connected to the wheel. A pair of wheel axles extend from the wheel and connect the wheel to the frame so that the wheel may rotate with respect to the frame. The frame also includes end pivot frames that provide a mounting point for end pivots to be removably attached to the frame. A zip cord may interact with a starting gear on one of the wheel axles to cause rotation of the wheel with respect to the frame.

A toy ring-launcher apparatus for wearing on a human finger as an item of play jewelry that's comprised of means for starting to rotate and then subsequently releasing other toy apparatuses or objects exhibiting gyroscopic tendencies, such as gyroscopic tops, flying propellers, or rolling wheels so they rotate very fast around a central axis and move independently of the toy ring-launcher apparatus on a flat surface, in the air, or on a toy racing track, respectively. Methods are also included for using the provided toy ring-launcher apparatus to have fun and enjoyment.
