| 20090258568 | Multi-function yo-yo - A multi-function yo-yo switchable between operation as a traditional yo-yo, a free-spin yo-yo, and a centrifugal-clutch yo-yo. Within one or both of the fly disks is one or more rotational-speed governors, and about the axle is a cylindrical axle sleeve which is rotatable about the axle. Each governor is spring-biased to an inwards position the governor contacts the axle sleeve, forcing the axle sleeve to rotate with the fly disks and axle. However, when the yo-yo spins sufficiently rapidly, the governors are thrown by centrifugal force to a radially-outwards position so as not to be in contact with the axle sleeve so that the axle sleeve may rotate independently of the fly disks. A function control switch locks the governors in the inwards position or the outwards position or allows the position to be controlled by centrifugal force. | 10-15-2009 |
| 20100022159 | YO-YO HAVING A STRING-FORMED RESPONSE SYSTEM - The invention is an improved yo-yo that has two side units and a string-formed response system incorporated into each side unit. In its most basic form, the response system employs a string that is threaded through spaced-apart apertures in a side unit to form at least one tether engagement pad. The pad may be contacted by the yo-yo's tether in order to cause a return of the yo-yo to a user's hand. | 01-28-2010 |
| 20100112894 | Expanding and contracting yo-yo - The expanding and contracting yo-yo is a spool formed by a pair of disks connected by a narrow diameter pin having a string wound around the pin. At least one, and preferably both, of the disks has a plurality of overlapping wings (also referred to as air foils or leaves) pivotally attached to the periphery of the outer face of the disk. The wings are capable of expanding outward to unfold like the petals of a flower and contracting to form a dome on the outer face, similar to a closed flower bud. The yo-yo has a flexible, resilient loop attached to the inner face of the wings to bias the wings to the closed dome configuration. When the yo-yo is dropped and pulled back in, centrifugal force, centripetal force, alternate lift and drag of air flow, and resilient bias cause the wings to alternately pivot and unfold outward, followed by pivoting inward to reform the dome shape. | 05-06-2010 |
| 20100317254 | YO-YO HAVING A PUSH-BUTTON LOCKING MECHANISM - The invention is a yo-yo that includes a user-actuable locking mechanism. The locking mechanism makes use of a laterally translatable assembly having a push button at each end and a center rotatable spool to which the yo-yo's tether is attached. Using the locking mechanism, a user can set the yo-yo so that the spool is either free to rotate, or must rotate with the yo-yo's sides. The yo-yo is also adapted for use with a spring-powered winder. | 12-16-2010 |

By replacing one set of replaceable rim pieces with another, a user can quickly and easily change the yo-yo's shape, look and/or functionality. To remove a rim piece, one first removes a lock ring that is secured to the rim piece and blocks a number of openings that lead to grooves in a center-located hub. Next, one employs a twisting movement of the rim piece to cause a number of tabs attached to the rim piece to slide in the hub's grooves until the tabs are aligned with the openings. The rim piece can then be disengaged from the yo-yo. | 12-16-2010 |
| 20110009029 | YO-YO HAVING QUICKLY-ADJUSTABLE RESPONSIVENESS - The invention is a yo-yo that includes movable shuttles that a user can quickly reposition between predetermined set points in order to adjust the yo-yo's responsiveness. Repositioning of the shuttles is accomplished via a cam surface connected to a rotatable dial. Preferably, the yo-yo also includes readily visible indicia associated with the shuttle's positioning apparatus so that a user can easily set and/or ascertain the yo-yo's responsiveness setting. | 01-13-2011 |
| 20110212665 | MOTORIZED YO-YO HAVING IMPROVED EFFICIENCY - The invention is a yo-yo that that has at least one side that incorporates components that create a powered rotation system. The system is connected to either a circuit board or a weighted board that is similarly rotatable and is located in the yo-yo's other side and/or employs a circuit board that is non-symmetric about its rotational axis and/or uses the powered rotation system to only push on a side portion's body member. | 09-01-2011 |

| 20120244781 | EXPANDING AND CONTRACTING YO-YO - The expanding and contracting yo-yo is a spool formed by a pair of disks connected by a narrow diameter pin having a string wound around the pin. At least one, and preferably both, of the disks has a plurality of overlapping wings (also referred to as air foils or leaves) pivotally attached to the periphery of the outer face of the disk. A biasing member causes the wings to remain in a closed dome configuration until the disks begin to spin. When the yo-yo is dropped and pulled back in, centrifugal force, centripetal force, alternate lift and drag of air flow, and resilient bias cause the wings to alternately pivot and unfold outward, followed by pivoting inward to a dome shape. In an alternative embodiment, the wings may be formed with a resilient living hinge that permits the wings to expand and contract against the body of the yo-yo. | 09-27-2012 |
