ABSTRACT:
The present invention relates to an improved yo-yo wherein a clutching device is disposed between the shaft and the disks such that the spinning stroke can be prolonged. The yo-yo includes first and second disks that are fixedly connected together by means of a shaft. A bushing is rotationally enveloped onto the shaft and is rotationally disposed within one of the disks. One of the disks is provided with a clutching device that is engaged with the bushing that is rotationally disposed therein by means of a resilient force. Wherein when those disks are spun, the centrifugal force generated thereof will overcome the resilient force such that the bushing will be released by the clutching device and the first and second disks and the shaft will spin independently to the bushing. When the spinning of the first and second disks and the shaft slows down, the clutching device engages the bushing again such that the bushing will spin with the first and second disks and the shaft jointly. By this arrangement, when the yo-yo is thrown downward and outward, the yo-yo will spin along the string. When the yo-yo reaches to the end of the string and by the function of the clutching device, the yo-yo will spin at the end of the string for a prolonged interval. When the spinning slows down, with the function of the clutching device, the yo-yo will spin upward along the string. By this arrangement, the player may conduct a plurality of acrobatic actions with the prolonged spinning interval.
