  • Patent number: 8814626
    Abstract: 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.

  • Patent number: 7740517
    Abstract: 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.

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.

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.

  • Patent number: 7419417
    Abstract: A yo-yo with an axle having two side-by-side bearings constituting a double bearing that enhances yo-yo performance characteristics by improving balance and reducing unwanted effects such as wobble, tilting, twisting, vibration, and string friction. Each bearing having an outer ring, an inner ring, and an array of balls trapped in tracks between the two rings. The outer rings of the bearings may be beveled to form a groove to enhance stability and centering of a string. Alternatively, the bearings may be covered with a bridge that has a straight outer surface or has an outer surface with a groove that could take several shapes. The bridge may have an internal ridge that acts as a centering mechanism for the bearing and bridge assembly. The inner and outer rings of the bearings may be independent or shared, and the rings of one bearing may overlap the rings of the other bearing. The inner rings of the bearings may be extended outward to provide spacing between bearing parts and yo-yo side walls.

  • Publication number: 20070224910
    Abstract: 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.

  • Patent number: 7175500
    Abstract: A yo-yo is disclosed with a substantially frictionless freely rotatable ball bearing, positioned upon a spindle between two separate halves of rotatable yo-yo members, such ball bearing having a smooth, continuous, outer concave surface. The smooth concave surface constitutes a segment of a circle having a radius of about 0.225 inches, contacting the yo-yo string, and is shallow, continuous and uninterrupted by the presence of a prior art groove formed in the outer surface. This surface configuration tends to urge the string towards the center of the bearing to reduce string friction against inside walls of the yo-yo halves while the string is winding around the bearing, yet allows some lateral movement of the string, enabling efficient performance of string layering maneuvers.

  • Patent number: 7125310
    Abstract: The invention is an improved yo-yo that features unique multi-piece sides. Each side has a removable disk that functions to affect the yo-yo's responsiveness via one or more tether engagement structures that can be contacted by the yo-yo's tether. When the removable disk is made of a resilient material, the disk can be compressed to change the yo-yo's responsiveness. Each removable disk may also form the associated side's rim and thereby functions to substantially define the side's shape. By replacing one set of removable disks with another, a user can quickly and easily change the yo-yo's shape and/or rim material and/or responsiveness.
