    • A wheeled transport device, such as luggage (8), a trash can, a garden cart or other hand cart configured to be manually wheeled in an inclined position by a pedestrian user, includes a collapsible handle (21) at one end and wheels at the other end (10). The wheels are independently connected to the device by respective suspensions (12) that exhibit a compliance, in response to forces applied to their respective wheels by the surface in a direction opposing wheel motion, selected to sufficiently alter suspension geometry to temporarily change an attitude, such as toe, camber or caster, of their respective wheels to counter a tendency of the device to overturn in response to the applied forces.
    • 诸如行李箱(8)的轮式运输装置,构造成由行人使用者以倾斜位置手动转动的垃圾桶,花园推车或其他手推车包括一端的可折叠手柄(21) 另一端(10)。 车轮通过相应的悬架(12)独立地连接到装置,悬架(12)响应于在相对于车轮运动的方向上由表面施加到它们各自的轮的力而被选择以充分改变悬架几何形状以临时改变姿态, 例如它们各自的车轮的脚趾,弯度或脚轮,以抵抗装置响应于所施加的力而翻转的倾向。
