Claim 8:
9. A vehicle with at least one expandable wheel, said expandable wheel comprising:
a rim disc, said rim disc defining a central aperture operable to receive an axle, said rim disc operable to rotate about said axle disposed within said central aperture, said rim disc further defining a plurality of rim disc channels, said rim disc channels having axle ends opposite drive ends;
a plurality of drive member connectors disposed around an outer circumference of said rim disc, said plurality of drive member connectors defining a plurality of drive member pivot apertures, said plurality of drive member pivot apertures operable to receive a plurality of drive member shafts;
said plurality of drive member shafts disposed within said drive member pivot apertures;
a plurality of drive members pivotally connected to said plurality of drive member shafts, said plurality of drive members having connector ends opposite head ends, said plurality of drive members defining sliding member drive pin apertures operable to receive sliding member drive pins of sliding levers;
a sliding lever disc, said sliding lever disc defining a central aperture operable to receive said axle, said sliding lever disc operable to rotate about said axle disposed within said central aperture, said sliding lever disc defining a plurality of sliding lever channels, said sliding lever channels having axle ends opposite drive ends; and
a plurality of sliding levers, said plurality of sliding levers having sliding ends opposite drive member ends, said plurality of sliding levers defining sliding lever channel pins at said sliding ends of said sliding levers, said sliding lever channel pins disposed within said rim disc channels and said sliding lever channels, said plurality of sliding levers each defining a sliding member drive pin at each of said drive member ends of said sliding levers, said sliding drive member pins disposed within said drive pin apertures of said plurality of drive members,
wherein said sliding ends of said plurality of sliding levers are positioned at said drive ends of said rim disc channels and sliding lever channels, and upon receipt of a rotational force applied to said sliding lever disc, said sliding ends of said plurality of sliding levers travel from said drive ends of said rim disc channels and sliding lever channels to said axle ends of said rim disc channels and sliding lever channels to pivot said drive members to move from a contracted position to an expanded position.
