US Patent 9642767 Personal mobility device

A personal mobility device includes a pair of rear legs and a pair of front legs pivotably connected to the rear legs via a pair of hubs. A handle, having a loop shape and including a grip portion, is slidably mounted within the pair of hubs so that the height of the grip can be adjusted. The hubs lock the front and rear legs in both an open (unfolded) and closed (folded) configuration. By sliding the handle downward through the hubs, the legs are unlocked from the open position and allowed to pivot until locked in the closed configuration. Conversely, by sliding the handle upward through the hubs, the legs are unlocked from the closed position and allowed to pivot until locked in the open configuration.
