Description

Multi-function yo-yo

Technical field

What the present invention relates to is a kind of yo-yo.

Background technology

Traditional yo-yo has two flying discs of closely being separated by, and the columniform symmetry axis of two flying discs is aimed at mutually.And two flying discs link together by the thin wheel shaft along the setting of the cylinder axis of symmetry.In traditional yo-yo, wheel shaft is attached on the flying disc, and not rotatable.Yo-yo comprises the rope on the wheel shaft.Basic yo-yo motor performance is: untie when the rope on wheel shaft, yo-yo is flown away from from the operator; Scroll up when rope is wrapped in wheel shaft, yo-yo will be got back to the operator place.The basic operation of the yo-yo campaign that another is traditional is for making its stagnation, that is, yo-yo is not regained rope immediately in the end rotation of the rope of untiing.Traditional yo-yo is stagnated needs some skills, and generally can only continue several seconds.

Free-axle yo-yo has with respect to the rotatable wheel shaft of flying disc.The operator can make free-axle yo-yo stagnate considerable time, and than making the easier dead state that reaches of fixedly wheel shaft yo-yo.Yet with fixing wheel shaft yo-yo ratio, free-axle yo-yo is not easy to make it to regain along rope after stagnation.

The patent No. of authorizing Michael S Kai Fulei June 1 nineteen eighty-two is 4,332,102 United States Patent (USP), has introduced a kind of yo-yo, and it has the spring-loaded clutch device that centrifugal force activates.When yo-yo during with the rotation of enough speed, centrifugal force outwards moves the clutch part 16 and 18 that is placed on the main body, breaks away from and the contacting of the central axle 20 of wheel shaft, so yo-yo is with regard to as the free-axle yo-yo general motion.Therefore, when with enough big strength " throwing " yo-yo, just be easy to it is stayed cool.Yet, when the rotary speed of yo-yo slows down or translational acceleration when changing sharp, clutch part 16 and 18 by spring 22 and 24 biasings catching central axle 20, just yo-yo this moment as fixing wheel shaft yo-yo general motion.Therefore, stagnate and just to be terminated, and yo-yo be easy to by draw rope or wait for up to the rotating speed of yo-yo slowly when enough, regain along rope.Thereby the advantage that centrifugal-clutch yo-yo has is to be easy to stagnate as free-axle yo-yo, and is easy to regain along rope as fixing wheel shaft yo-yo.
