Abstract

A stair climbing wheel and vehicles are described. The stair climbing wheel has a rolling wheel and a plurality of deployable protrusions that allow the wheel to climb stairs. The deployable protrusions can be deployed from or retracted into the rolling wheel. In the retracted position, the stair climbing wheel functions as a traditional circular wheel. These stair climbing wheels can be incorporated on a wide variety of vehicles, such as hand trucks, wheelchairs, and personal transports to allow these vehicles to climb stairs.
