Mobility device having walking wheel assembly for moving an object across non-planar areas

A mobility device for moving an object across a surface, said mobility device comprising:

• a walking wheel assembly having at least a first wheel, a second wheel, an offset camshaft interconnecting said first wheel and said second wheel and an axle bolt sized and configured to extend through said offset camshaft and each of said first wheel and said second wheel so as to clamp said first wheel, said offset camshaft and said second wheel together, each of said first wheel and said second wheel made out of materials selected to move said mobility device across the surface, said offset camshaft having a first lobe associated with said first wheel and a second lobe associated with said second wheel, said offset camshaft structured and arranged with said first lobe in a non-linear relationship with said second lobe so as to define one of said first wheel and said second wheel as a leading wheel and the other of said first wheel and said second wheel as a trailing wheel, said offset camshaft further structured and arranged to pivot one of said first wheel and said second wheel upward or downward relative to the other of said first wheel and said second wheel when one of said first wheel and said second wheel contacts a non-planar area on the surface;
• and
• an attachment means for attaching said walking wheel assembly to said object so as to moveably support the object on the surface and across or over the non-planar area.
