摘要： The present invention configures a pushcart, in particular a baggage cart such as is used in airports, for ease of maneuverability in negotiating an escalator stairway. The cart is fitted with a front wheel assembly and pivotable rear wheel assemblies, as well as with drop-attenuating mechanisms fitted to each wheel assembly. The rear wheel assemblies each include a reverse-releasable, pivoting-lock mechanism. The drop attenuating mechanisms function when the pivotable wheel assemblies are locked in the pushcart advancing direction, and include damped-swing traction members for establishing adhesive friction in contacting the treads of a sloping escalator stairway. The traction members bear the pushcart through a damped swing if the wheel assemblies are not riding on the treads of the escalator steps. The pushcart user can readily orient the vehicle toward an escalator by slightly backing up the cart, swinging it into the desired orientation, and then, by pushing the cart forward, the rear wheel assemblies automatically lock straight ahead. Thus, the wheel drop attenuators are able to function effectively to smooth the dropping of the pushcart in case the wheels are caught on the edges of the escalator stairway as it slopes.

摘要翻译： 本发明构造了一个手推车，特别是诸如在机场中使用的行李车，以便于在谈判自动扶梯楼梯时的机动性。 推车配备有前轮组件和可枢转的后轮组件，以及装配到每个车轮组件的落下衰减机构。 后轮组件各自包括可反向释放的枢转锁定机构。 当可枢转的轮组件被锁定在手推车行进方向时，下落衰减机构起作用，并且包括用于在倾斜的自动扶梯楼梯的胎面接触中建立粘合摩擦的阻尼摆动牵引构件。 如果车轮组件没有骑在自动扶梯踏板的踏板上，则牵引构件通过阻尼摆动承载推车。 手推车用户可以通过轻轻地将手推车推向自动扶梯，将其摆动到期望的方向，然后通过向前推动推车将后轮组件自动锁定在前方，从而容易地将车辆定向到自动扶梯。 因此，车轮落下衰减器能够有效地起作用，以便在滑轮倾斜时将轮子卡在自动扶梯楼梯边缘的情况下平滑手推车的落下。

摘要： A stairway ascending/descending vehicle which may ascend/descend the steps of the stairs having a height greater than a diameter of wheels and in which vertical vibration is suppressed. The stairway ascending/descending vehicle has main shafts rotatably supported on a front portion and a rear portion of a vehicle body, respectively. Front arm members 4L and 4R are mounted to the front main shafts, and rear arm members 5L and 5R are mounted to the rear main shaft, the front and rear arm members are configured to rotate with respect to the main shafts. Front wheels 6a and 6b are mounted on the front arm members and rear wheels 7a and 7b are to the rear arm members. Torque transmitted from each of the main shafts is transmitted through a first gear 12 connected to the main shafts to second gears 13a and 13b and third gears 14a and 14b to the wheels, the gears 12, 13a, 13b, 14a and 14b all being supported within the arm members, the gears 14a and 14b being connected to the wheels. The gear ratio defined by the gears 12, 13a, 13b, 14a and 14b determine whether the vehicle body 1 climbs a stairway in either a crawling mode or a rotational mode.
