Abstract

A dynamic collapsible and revolving toy, comprising an interior sleeve set and an exterior sleeve set that are installed at the center inside a base, said interior sleeve set involves a winding strip and driven by a piece of extension/retraction driving motor, the exterior sleeve set covers the outside of the interior sleeve set, which innermost sleeve is linked to the innermost sleeve of the interior sleeve set, and is able of extending/retracting functions when driven by the extension/retraction driving motor, on the upper rim of each sleeve of the exterior sleeve set are inserted a decorative article suited to the theme of the toy, to the base of the outermost sleeve is linked a gear which is toothed with and driven by a rotation driving motor, when the user turns on the power switch on one side of the base, the extension/retraction driving motor is started to drive a winding strip to push out the interior and exterior sleeve sets from the base, so they are erected right above the base, then the gear on the base of the exterior sleeve set touches and activates a first micro switch located on one side of the sleeve set, thereby activating the rotation driving motor, so on one hand, it controls a reduction gear to drive the exterior sleeve set to rotate slowly, while on the other hand, it drives the control circuit installed inside the base to play melodious music and flash the LED lamps hanging on the decorative article, when the user turns on another operating switch, it will turn off the music and LED, and drive the extension/retraction driving motor to turn in a reverse direction, then the extended interior and exterior sleeve sets will be retracted into the base, until after the gear on the base of the exterior sleeve set touches another second micro switch, it will automatically cut off power and restore to its idle status, so the operation is quite easy and convenient and the movement is fun and smooth, giving much fun and novelty to the theme of the toy.

A dynamic collapsible revolving toy, comprising:

a base;
a take-up box within said base;
a winding shaft disposed within said take-up box;
a winding strip comprised of a flexible, thin material having one end wound on said winding shaft;
an interior sleeve set disposed essentially at a center of said base, said interior sleeve set including a plurality of nesting tube sleeves interlinked together, an innermost one of said nesting tube sleeves being linked to another end of said winding strip;
an exterior sleeve set concentrically disposed around said interior sleeve set so as to cover said interior sleeve set, said exterior sleeve set including a plurality of nesting tube sleeves interlinked together, an innermost one of said nesting tube sleeves of said exterior sleeve set being linked to said innermost one of said nesting tube sleeves of said interior sleeve set, so that said interior sleeve set and said exterior sleeve set are collapsible and extendible together, each one of said nesting tube sleeves of said exterior sleeve set having a rim on a top portion thereof, said rims being adapted to receive a decorative article, each said nesting tube sleeve of said exterior sleeve set further having a protruding block that engages with a protruding block of an adjacent nesting tube sleeve of said exterior sleeve set, so that adjacent ones of said nesting tube sleeves of said exterior sleeve set are interdriven to rotate;
a gear attached to a base of an outermost one of said nesting tube sleeves of said exterior sleeve set, said gear being vertically displaceable to upper and lower vertexes of displacement;
a first driving motor attached to said take-up box and transmitting a driving force to drive said winding shaft and cause said exterior sleeve set and said interior sleeve set to extend and retract via said winding strip;
a second driving motor attached to an inside of said base, said second driving motor transmitting a driving force to drive and rotate said gear, thereby causing said exterior sleeve set to rotate;
a first micro switch activatable when said gear is displaced to the upper vertex of displacement;
a second micro switch activatable when said gear is displaced to the lower vertex of displacement;
and
a control circuit disposed in said base, said control circuit including drive circuits to control the first and second driving motors in dependence on an activation or deactivation of said first and second micro switches.
