Abstract:
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; anda 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.
