Claim:
1. A gravity-assisted rotational novelty system comprising at least two concentric rotational members having different sizes and rotatable about the same rotational center or shaft, and at least one pair of link members connected between the above concentric rotational members, interference sections being at least disposed on a large-size rotational member and a small-size rotational member in different rotational directions, the link members being restricted within the interference sections, the interference sections of the large-size rotational member serving to provide supporting force for the link members that rotate and descend, while the interference sections of the small-size rotational member serving to provide supporting force for the link members that rotate and ascend, wherein the rotational members include a first rotational ring, a second rotational ring, a third rotational ring and a rotational disc, which are concentric with decreasing sizes, each of the link members being composed of a link bar and a weight body connected with the link bar, the interference sections disposed on the first rotational ring being second interference sections, the interference sections disposed on the second rotational ring being first interference sections, the weight bodies being arranged around the first rotational ring, the link bars being formed with through holes near inner ends of the link bars for pivotally connecting the link bars with the rotational center or shaft, the link bars being further respectively formed with stabilization points for pivotally connecting with first pivot points of the rotational disc, the link bars being restricted within different interference sections of the rotational members; and wherein the rotational mechanism further includes a coupling wheel mounted on the rotational center or shaft, the coupling wheel being coupled with an actuation device and a generator.
