In accordance with the principals of the present invention, a desk or executive curio is provided. A rotor assembly includes a rotor and a shaft. A housing assembly defines inner pivoted supports that allow rotation of the rotor about an inner pivotal axis. The housing assembly further defines outer pivoted supports that allow rotation of the housing about an outer pivotal axis perpendicular to the inner pivotal axis of the rotor assembly. Bearings allow the rotor assembly and the housing assembly to be held in an axis perpendicular to a rotor axis. The rotor assembly and the housing assembly are removably connectable to a base along the inner pivotal axis, the base having an offset center of gravity and defining a curved outer surface.

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 top toy includes a body and a shaft part being detachably attached to the body. The body includes a trunk main body, a first tip, and a second tip. The trunk main body includes an arc shaped hole with first and second ends. First and second insertion pieces of the first and second tips respectively are inserted in the arc shaped hole at the first and second ends respectively. The trunk main body includes a moving part being manually operated between first and second positions. In the second direction, a space, the resistance element, the first coupling member are aligned in order when the first tip is employed. In the first direction, the space, the second coupling member, and the resistance element are aligned in order when the second tip is employed. The body and the shaft part are to be detached at the space.

A top toy includes a body including a first coupling element, and a shaft part being detachably attached to the body and including a second coupling element and a projection. The first and second coupling elements abut each. The body and the shaft part are detachable when the body is rotated relative to the shaft part. The body includes a rotating blade being configured on an outer circumference part thereof to be rotated. The rotating blade includes a shaft extending parallel to the axial direction and is configure to advance and retreat with respect to the arc shaped slit. The rotating blade includes a sliding part at an inner edge which is formed in a bow shape. The rotating blade is configured to be rotated around the shaft by the sliding part being slidably in contact with the projection.

An upper part includes an upward facing surface and a rod-shaped shaft being vertically movable. A lower part includes a downward facing surface and a tubular shaft in which the rod-shaped shaft is inserted. The upper part is relatively rotatable against the lower part and being detachably attached to the lower part. A lower tip is configured to protrude from a lower end of the tubular shaft when the upper part is attached to the lower part and when the lower tip is in no contact with a floor. The lower tip is accommodated in the tubular shaft when the upper part is attached to the lower part and when the lower tip is in contact with the floor. A second engaging part is configured to restrict a relative rotation between the upper part and the lower part when the lower tip is in no contact with the floor.

A mechanical spinning robot toy includes a top section and a bottom exposed outer gear section. The top section resembles a robot possibly including a head portion and a body portion which may be integral. Any of a variety of arm-like appendages extends outward from the body. The spinning drive mechanism is within the top section. The bottom section has teeth or cogs capable of meshing with another gear or a rack on any of a variety of accessories to move the robot along a track or to animate the accessories. A lower weighted convex surface portion in the bottom biases the robot upright and facilitates spinning of the robot upright. The top and bottom sections are frictionally fit together to rotate or spin together and to spin separately with respect to each when either the top or bottom sections are not allowed to spin.
