A yo-yo includes an adjustable clutch mechanism having a pair of arms having flyweights mounted thereto and pivotally mounted within a cavity in one of the yo-yo halves. The arms include gear teeth that mesh with gear teeth on a movable member such that pivoting of the arms causes linear actuation of the movable member. The movable member includes engagement teeth that engage a spool. An adjuster mechanism includes a threaded bolt and a limiter threaded onto the bolt. The limiter is positioned by rotating the bolt. The position of the limiter determines the range of motion of the movable member.

A yo-yo including a pair of yo-yo body halves each formed as a composite having an inner hub, a central preferably dish-shaped main body portion defining an inward facing surface and an annular-shaped peripheral body portion. An axle is threadably engaged at each end thereof into a hub thread formed into each hub along an axis of rotation of the yo-yo. Each hub also includes a shoulder positioned radially adjacent the hub thread which, when the axle is fully tightened in frictional engagement into each hub thread by tightening rotation between the body halves, bear against one another to define a minimum gap between the inward facing surfaces of the body halves. A miniature bearing is also provided having an inner ring tightly frictionally engaged over each shoulder, each end of the bearing extending into an annular recess formed into each inward facing surface adjacent to the hub to maintain a tether in wrapped engagement around an outer ring of the bearing. The outer ring is freely rotatable with respect to the body halves and the axle, the axle rotating with the body halves when the yo-yo is spinning. The axle, when the body halves are forcibly rotated in an axle disengaging direction one to another, causes a corresponding increase in the width of the gap. Each inner facing surface is preferably arcuately shaped whereby the gap very gradually increases in width in a direction radially outwardly from the outer ring.

A yo-yo comprising right and left bodies surrounded by thick, radially anchored, soft rubber outer cushions has a string gap having a contour that includes an innermost gap which is narrower than other regions of the string gap. The string gap may have a narrowed neck region located between the innermost gap and the outer diameter of the yo-yo. The yo-yo may include an axle which is permitted to rotate within the left body of the yo-yo but retained by a locknut seated in the right body of the yo-yo.

A device for holding and controlling a string-retained article, such as a yo-yo, wherein the device comprises an annular ring of rigid material with a smooth annular channel formed in an outer surface of the ring. The annular channel is defined by an annular base ring and first and second annular ridges. A loop of a string can be retained in the channel so that the ring will be interposed between a body part of a user and the loop of the string to prevent constriction of the loop about the body part of the user. The ring can be used in practicing a method for holding and controlling a string-retained article comprising the steps of providing a string, the ring, and a string-retained article such as a yo-yo; coupling a first end of the string to the string-retained article, forming a second end of the string into a loop; disposing the loop of the string in the channel of the ring; and inserting a body part of a user through the aperture in the ring. Where the string-retained article is a yo-yo, one could further wrap the string around an axle of the yo-yo until the yo-yo is disposed adjacent to the ring, cast the yo-yo from the body part of the user to cause the string to unwrap and the yo-yo to gain angular momentum, and then induce the yo-yo to return to a position adjacent to the ring.

The invention is a yo-yo that employs an active starburst tether engagement system located in one or both of the yo-yo's side members. The system makes use of a starburst-shaped array of movable engagement ribs that face the tether and are located near the yo-yo's axle structure. Each rib is independently movable and is located at the end of a flexible finger that enables the rib to be moved by the tether in a direction substantially parallel to the yo-yo's axis of rotation.

A yo-yo includes a first yo-yo half defining a first starburst, a second yo-yo half defining a second starburst, and an axle fixedly mounted between said yo-yo halves. The yo-yo also includes a roller bearing fixedly attached to the axle, and a spool fixedly attached to the roller bearing, the spool having a circumferential outer rim with a groove therein. A bearing pocket defines an annular radial gap between each yo-yo half and the outer rim, the gap sufficiently small that a string cannot wedge in the gap.

A yo-yo includes a yo-yo body having first and second halves joined together with an axle. A string is interconnected at one end to the axle and at the opposite end to a solid body. Tricks may be executed using the yo-yo, including selectively releasing the solid body, supporting the yo-yo by the string at a point on the string between the solid body and the yo-yo body, and throwing the yo-yo body and solid body in the air and catching the solid body.

A device for attachment of a yo-yo type toy to a finger is provided which has a durable eyelet reinforced leather strap of sufficient length to wrap at least half way around the finger when attached to a string of the yo-yo. The string is connected to the device when a reduced size slipknot is created and passed through the eyelets before closing therefore enclosing the eyelets in the adjustable loop of the slip knot. When the finger is inserted outside of the loop of the slip knot between the outside top of the slip knot and the device and the slip knot is constricted, the eyelets are pulled together causing the invention to constrict around the finger providing a stable attachment to the finger.

A yo-yo structure utilizing a pair of disks connected by a spindle. The disks form a groove to confine a line connected to the spindle. A cover of soft flexible material fits over at least one of the disks. A shield is fixed in the vicinity of the groove between the disks to prevent portions of the cover from entering the groove when the yo-yo is operating.

A yo-yo includes a pair of rotary elements spaced from each other and each having a cavity, a bearing portion formed on each of the pair of rotary elements at a center thereof, and an axle detachably received in the bearing portion so as to be rotatable together with the pair of rotary elements. The axle has an engaging portion formed at each of opposite ends thereof. The axle is loosely inserted into a generally cylindrical spool interposed between the pair of rotary elements. A locking device having a pair of locking parts is mounted in the cavity, and the pair of locking parts have respective holding portions for detachably holding the engaging portion therebetween.
