  • Patent number: 5400534
    Abstract: A decoration includes a hollow base assembly, a bulb, a sound generating unit, a motor, a mounting ring fixed on the base assembly, several superposed intermediate rotary rings disposed between the mounting ring and the base, and an upper rotary ring disposed on and above the mounting ring. Any adjacent two of the upper rotary ring, the mounting ring, the intermediate rotary rings and the base have a bearing mechanism which includes several circumferentially spaced-apart ball positioning units, and several balls respectively positioned within the ball positioning units. The balls are confined in the ball positioning units so as to facilitate relative rotation between any adjacent two of the upper rotary ring, the mounting ring, the intermediate rotary rings and the base. When the motor is powered, the upper rotary ring and the intermediate rotary rings rotate relative to the base assembly and the mounting ring.
