Abstract:
1. A cane comprising: at least one substantially vertical member; at least one handle; a base; four wheels; and four rigid support structures; wherein said base is comprised of four wheel bases; wherein said at least one handle is attached to a top end of said at least one substantially vertical member; wherein a lower end of said at least one vertical member is attached to a top surface of said base; wherein each of said four wheels is attached to one of said four wheel bases; wherein each of said four rigid support structures is attached to said base distally to each of said four wheels; wherein said four wheels extend from a bottom surface of said base and wherein said four wheels extend further away from said base than said four rigid support structures, such that said cane rolls along a ground surface being traversed by a user without said four rigid support structures contacting said ground surface; wherein said four rigid support structures are fail-safe brakes; wherein each of said at least one four wheels is retractably connected to one of said four wheel bases, such that when a force is applied downwards on said at least one substantially vertical member, said four wheels retract into said four wheel bases such that said four rigid support structures contact said ground surface; wherein said base is substantially rectangular and has four corners; wherein said four wheel bases are positioned substantially at said four corners of said base; and wherein said four rigid supporting structures are positioned substantially at said four corners of said base and extend distally beyond said four wheels such that when said cane is tilted away from said substantially vertical position in any direction one or more of said four rigid supporting structures will come into contact with said ground surface.
