| 1999 | Invention patented by Shin-Ya Yang on August 10th, 1999. Abstract: An ascending/descending mechanism in which a face gear is rotated to drive two symmetrically arranged cylindrical gears, whereby two eccentric shafts fitted with the cylindrical gears are rotated in reverse directions. Two driven slide blocks are fitted with the short shafts of the eccentric shafts. The top ends of the driven slide blocks are fitted with two columns which are fitted in fitting holes of retaining blocks. When the cylindrical gears are reversely rotated, the short shafts of the eccentric shafts are slided within the slide slots of the driven slide blocks, whereby the columns are reciprocally moved up and down. Accordingly, the dolls or decorative articles at the top ends of the columns are alternately ascended or descended. The power source for driving the face gear can be a music bell or a motor, so that when the dolls or decorative articles at the top ends of the columns are alternately ascended or descended, a music or other audio/video effect is cooperatively created. |
