PERSONAL MOBILITY DEVICE

摘要

A personal mobility device includes a frame including first, second, third, and fourth frame members. The first and second frame members are connected, such as by a pivot joint. The third and fourth frame members are connected to collapse in the same plane as the first and second frame members. The first and third, and second and fourth, frame members are also connected via hinges. This allows the device to fold ("collapse") and unfold ("expand") substantially simultaneously in two substantially orthogonal planes. A tension wire assembly is provided that biases the frame into a collapsed configuration; a locking mechanism is provided that holds the frame in an expanded configuration.
