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.
Claims19
A yo-yo comprising:
- first and second side units secured together in a spaced-apart relation by an axle structure;
- a tether secured to a portion of said axle structure;
- and
- wherein said first side unit comprises a member, a string and a plurality of securement members, wherein said member includes a front surface and a rear surface, wherein said front surface faces said second side unit, wherein said member includes a plurality of apertures through which said securement members extend, wherein said string is secured to said member at multiple spaced-apart locations by the securement members in a manner whereby said string is predominantly located on said front surface and forms a plurality of tether engagement pads located on said front surface and wherein when said yo-yo is sleeping, said pads are capable of facilitating a return of said yo-yo to a user's hand.

A yo-yo comprising:
- first and second side units secured together in a spaced-apart relation by an axle structure;
- a tether secured to a portion of said axle structure;
- and
- wherein said first side unit comprises a first member, a string and a plurality of securement members, wherein said first member includes a front surface and a rear surface, wherein said front surface faces said second side unit, wherein said securement members are operatively connected to said first member, wherein said first member includes a plurality of apertures through which said securement members extend, wherein said securement members engage said string at spaced-apart locations in a manner whereby said string forms a plurality of tether engagement pads located on said front surface and wherein when said yo-yo is sleeping, said pads are capable of facilitating a return of said yo-yo to a user's hand.
1 more element
A yo-yo comprising:
- first and second side units secured together in a spaced-apart relation by an axle structure;
- a tether secured to a portion of said axle structure;
- a first member that forms a portion of said first side unit and includes a front surface that faces the second side unit;
- a second member that forms a portion of the first side unit, and wherein said second member is movable relative to said first member;
- a plurality of string securement members operatively connected to said second member;
- a plurality of apertures in said first member through which a plurality of the string securement members extend;
- and
- a string secured to said front surface of said first member by a plurality of said string securement members, and wherein portions of said string form tether engagement pads that are capable of facilitating a return on command of the yo-yo when said yo-yo is sleeping.
5 more elements
A yo-yo comprising:
- first and second side units;
- an axle structure that secures together said first and second side units in a spaced-apart relation, and wherein a tether can be secured to a portion of said axle structure;
- wherein said first side unit has a surface that faces said second side unit and wherein said surface includes a plurality of spaced-apart apertures;
- a plurality of securement members secured to a portion of said first side unit, and wherein each of said securement members extends through a different one of said apertures;
- and
- an elongated flexible member secured to said first side unit at spaced-apart locations by said securement members, wherein said flexible member forms at least one pad member located on said surface of said first side unit, and wherein when a tether is secured to said axle structure and said yo-yo is sleeping, said tether is capable of engaging said at least one pad member in a manner that will result in said tether winding about said axle structure.
3 more elements
A yo-yo comprising:
- first and second side units;
- an axle structure that secures together said first and second side units in a spaced-apart relation, and wherein a tether can be secured to a portion of said axle structure;
- wherein said first side unit has a first surface that faces said second side unit and a second surface that faces away from said second side unit, and wherein said first side unit also has a member that includes a plurality of apertures;
- and
- a plurality of tether engagement pads located on said first surface and secured to said member, wherein each of said pads is formed by an elongated flexible string that extends through said member and has end portions located adjacent said second surface, and wherein when a tether is secured to said axle structure and said yo-yo is sleeping, said tether is capable of engaging at least one of said tether engagement pads in a manner that will result in said tether winding about said axle structure.
