    摘要： A wheeled transport device, such as luggage, 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 at one end and wheels at the other end. The wheels are independently connected to the device by respective suspensions 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.

    摘要翻译： 轮式运输装置，例如行李箱，垃圾桶，花园推车或其他手推车，其被构造成由行人使用者在倾斜位置手动转动，在一端包括可折叠手柄，另一端包括轮子。 车轮通过相应的悬架独立地连接到装置上，这些悬挂装置响应于在相对于车轮运动的方向上被表面施加到它们各自的轮子上的力而被选择以充分改变悬架几何形状以临时改变姿态，例如脚趾 ，弧形或脚轮，以抵抗装置响应于所施加的力而推翻的倾向。
