Abstract
A personal transportation device having first and second elongated foot support member that are arranged substantially in parallel and approximate to some extent the experience of skiing. The lateral distance of the foot support members may be adjusted. Biased-direction caster wheels may be provided that permit propulsion from side to side movement as well as kicking off and other propulsion techniques. Tiltable steering assemblies are disclosed that may impart a tilting of a front wheel to achieve turning. Various embodiments are disclosed.
Claims20
A personal transportation device, comprising:
- a first elongated foot support member;
- a first front caster wheel assembly and a first rear caster wheel assembly that are coupled to the first foot support member, the first front caster wheel assemble including a first biased-direction caster wheel;
- a second elongated foot support member;
- a second front caster wheel assembly and a second rear caster wheel assembly that are coupled to the second foot support member, the second front caster wheel assembly including a second biased-direction caster wheel;
- a linkage assembly coupled to the first and second foot support members and configured to maintain the foot support members in a substantially parallel arrangement with one another;
- and
- a first ascending steering member;
- wherein the first caster wheel and the first ascending steering member are coupled to one another and configured such that, in use, lateral movement of the first ascending member causes a turning of the first caster wheel.
