Abstract:
A vibration mechanism for a motion toy, comprising:a hollow, cylindrical frame including a seat on a top surface adjacent an edge thereof; a pair of upright cylindrical rollers pivotably mounted in the seat, each of the rollers including a gear so that a rotation of one roller is capable of causing the other roller to rotate in an opposite direction and a plurality of equally spaced apart longitudinal first ribs on an inner wall thereof, the first ribs being tapered from bottom to top, and one of the rollers further including a drive link extended horizontally from a circumference thereof; drive means disposed in the frame, the drive means including a shaft extended upward above the frame, a horizontal rod having one end coupled to an upper end of the shaft, and a transmission rod having one end pivotably coupled to the other end of the horizontal rod and the other end pivotably coupled to an open end of the drive link; and a decorative member formed of a flexible bundle of plastic optical fibers and disposed in each of the rollers, each of the decorative members being mounted in a plastic mounting cylinder by applying low heat of joining, the mounting cylinders being adapted to snugly fit in the rollers so that the decorative members are fastened in the rollers by tightly urging the first ribs of the roller against the mounting cylinders when the decorative members are mounted in the rollers; wherein in response to a rotation of the drive means, the transmission rod rotates as the horizontal rod rotates, the drive link vibrates, one of the rollers rotates as the other roller rotates, and the decorative members vibrate in the rollers vibrate rhythmically.
