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.
Claims28
A yo-yo comprising:
- first and second side portions secured together in a spaced-apart relation by an axle structure;
- a tether secured to a portion of said axle structure;
- a hub that forms a portion of said first side portion and includes a tether-facing surface;
- and
- a disk located adjacent said hub and secured to said hub, wherein said disk has a tether engagement member that forms an integral portion of said disk and extends through an aperture in said hub, wherein said member has an end portion that can be contacted by a portion of said tether located between said side portions, and wherein a portion of said disk at least partially forms a rim of the first side portion;
- a user actuable member operatively connected to said disk and enables said tether engagement member to be adjustably positionable relative to the tether by causing the disk to be compressed which moves the tether engagement member closer to said tether.

A yo-yo comprising:
- first and second side portions secured together in a spaced-apart relation by an axle structure, and wherein each of said side portions is an assemblage of parts;
- a tether secured to a portion of said axle structure;
- first and second hubs, wherein said first hub forms a portion of said first side portion and said second hub forms a portion of said second side portion, and wherein each of said hubs has a tether-facing surface;
- first and second replaceable disks;
- wherein said first replaceable disk is non-rotatably secured to said first hub, at least partially forms a rim portion of the first side portion, and has a tether engagement member that extends through an aperture in said first hub whereby an end of said tether engagement member can be contacted by a portion of said tether located between said side portions and is sized whereby it can slide completely through said aperture;
- a user actuable member operatively connected to said first disk and enables said tether engagement member to be adjustably positionable relative to the tether by causing the disk to be compressed which moves the tether engagement member closer to said tether and
- wherein said second replaceable disk is non-rotatably secured to said second hub, at least partially forms a rim portion of the second side portion, and has a tether engagement member that extends through an aperture in said second hub whereby said tether engagement member can be contacted by a portion of said tether located between said side portions.

- a tether secured to a portion of said axle structure;
- a hub that forms a portion of said first side portion and includes a tether-facing surface;
- a disk secured to said hub and having a fixedly-attached portion that forms a tether engagement member that extends through an aperture in said hub, and wherein said member has an end portion that can be contacted by a portion of said tether located between said side portions;
- and
- a securement member operatively engaged to said hub and that functions to secure said disk to said hub and that enables said tether engagement member to be adjustably positionable relative to the tether by causing the disk to be compressed which moves the tether engagement member closer to said tether.
