    • 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. Alternatively, tendons can bias the frame into an expanded configuration.
    • 个人移动设备包括包括第一,第二,第三和第四框架构件的框架。 第一和第二框架构件例如通过枢转接头连接。 第三和第四框架构件在与第一和第二框架构件相同的平面中连接成塌缩。 第一和第三和第二和第四框架构件也通过铰链连接。 这允许装置在两个基本上正交的平面上基本上同时折叠(“崩溃”)并展开(“展开”)。 提供了将框架偏压成折叠构造的张力线组件; 提供了一种将框架保持在扩展构型中的锁定机构。 或者,腱可以将框架偏置成扩展构型。
