An extending, collapsing and rotating toy moves from a collapsed position (Fig 2) to an extended position by means of a motor 30 operating via gears and a flexible strip 42. The toy comprises a base 10 with a gear plate 40 driven to rotate by a gearbox 30. There is an interior tube set 50 and an exterior tube set 60 disposed above the base. The innermost tube 63 of the exterior tube set is connected to the innermost tube 51 of the interior tube set and the outermost tube 64 of the exterior tube set is mounted on the gear plate. The flexible strip is coiled on a ring slot 41 of the gear plate and is connected to the innermost tube 51 of the interior tube set. A plurality of collars 70 are mounted outside the exterior tube set for hanging decorative articles. A control circuit 12 enables the gearbox to provide clockwise or counter-clockwise rotation and accelerated or decelerated rotation. When a switch 13 located on the base is pushed, a built-in IC program of the control circuit will then control the gearbox to output rotating power for extending/retracting the interior tube set, exterior tube set and the collar set from/to the base. The toy may also play music and have lamps, and it may represent a Christmas tree, a multi-layered cake or the Eiffel Tower. |
